ITEM 1. BUSINESS.
General / Corporate Overview
We are a holding company for specialty property and casualty insurance companies focused on professional liability insurance. Our executive offices are located at 100 Brookwood Place, Birmingham, Alabama 35209 and our telephone number is (205) 877-4400. Our stock trades on the New York Stock Exchange under the symbol “PRA.” Our website is www.ProAssurance.com.
The Investor Relations section of our website provides many resources for investors seeking to learn more about us. Whenever we file a document or report with the Securities and Exchange Commission (the SEC) on its EDGAR system, we make the document available on our website as soon as reasonably practical. This includes our annual report on Form 10K, our quarterly reports on Form 10Q and our current reports on Form 8K. We show details about stock trading by corporate insiders by providing access to SEC Forms 3, 4 and 5 when they are filed with the SEC. We maintain access to these reports for at least one year after their filing.
In addition to federal filings, we make available copies of the financial statements we file with state regulators, news releases that we issue, and certain investor presentations. We believe these documents provide important additional information about our financial condition.

In addition you will find up-to-date copies of documents detailing our Code of Ethics and Conduct, Corporate Governance Principles and Share Ownership Guidelines for Management and Directors. We also provide copies of the Pre-Approval Policy and Procedures for our Audit Committee and our Policy Regarding Stockholder-Nominated Director Candidates.

Box 590009, Birmingham, Alabama 35259-0009, or by telephone at (205) 877-4400 or (800) 282-6242.
Because the insurance business uses certain terms and phrases that carry special and specific meaning, we urge you to read the Glossary included at the end of Item I prior to reading this report.
General / Business Overview

We maintain 16 local claims and/or underwriting offices to ensure that we have a local presence in the markets we serve. This emphasis on local knowledge allows us to maintain active relationships with our customers and be more responsive to their needs.
We believe this local knowledge allows us to be more effective in evaluating claims because we have a detailed understanding of the medical and legal climates of each market. Our insureds value the attention we give to each claim and our willingness and ability to defend non-meritorious claims is a key factor that differentiates us from our competitors.
We rigorously underwrite each application for coverage to ensure that we understand the risks we accept, and are able to develop an adequate price for that risk. By ensuring that we charge an adequate rate, we seek to maintain the strong financial position that allows us to protect our customers in the long-term.
We believe our financial strength, commitment to a local market presence and personal service have allowed us to establish a leading position in our markets, thus enabling us to effectively compete on a basis other than just price.
General / Financial Overview
For the year ended December 31, 2005, we generated $573.0 million of gross premiums written, $543.2 million of net premiums earned and $645.3 million of total revenues. As of December 31, 2005, we had cash and invested assets of $2.665 billion, total assets of $3.909 billion and stockholders’ equity of $765.0 million.
For the year ended December 31, 2005, our combined ratio was 97.1%. A combined ratio below 100% indicates profitable underwriting prior to the consideration of investment income. However, if investment income is considered, companies writing professional liability insurance may be profitable with combined ratios above 100%. Thus, the combined ratio may not always be indicative of our ultimate results because of the “long-tail” nature of the professional liability business.
In order to measure the effect of investment income, we also measure our results by calculating our operating ratio. We measure our overall results by calculating our Return on Equity.

Corporate Organization and History
We were incorporated in Delaware in June 2001 to serve as the holding company for Medical Assurance, Inc. (Medical Assurance) in connection with its acquisition of Professionals Group, Inc. (Professionals Group). Our core operating subsidiaries are The Medical Assurance Company, Inc., ProNational Insurance Company, NCRIC Insurance Company, Inc., and Red Mountain Casualty Insurance Company, Inc. We also write a limited amount of medical professional liability insurance through Woodbrook Casualty Insurance Company, Inc. (formerly Medical Assurance of West Virginia, Inc.), which we consider to be a non-core operating subsidiary. We are the successor to twelve insurance organizations and much of our growth has come through mergers and acquisitions. In each, we retained key personnel, allowing us to maintain a local presence and preserve important institutional knowledge in claims management and underwriting. We believe that this ability to utilize local knowledge in claims and underwriting is a critical factor in the operation of our companies. Our successful integration of each organization demonstrates our ability to grow effectively through acquisitions.
Our predecessor company, Medical Assurance, was founded by physicians as a mutual company in Alabama and wrote its first policy in 1977. We demutualized and became a public company in 1991. Medical Assurance expanded through internal growth and the acquisition of professional liability insurance companies with strong regional identities in West Virginia, Indiana and Missouri, along with books of business in Ohio and Missouri.
Professionals Group traces its roots to the Brown-McNeeley Fund, which was founded by the State of Michigan in 1975 to provide medical professional liability insurance to physicians. Physicians Insurance Company of Michigan, which ultimately became ProNational, was founded in 1980 to assume the business of the Fund. That company also expanded through internal growth and the acquisition of a book of business in Illinois and the acquisition of professional liability insurers in Florida and Indiana.
Recent Transactions
In 2005 ProAssurance acquired NCRIC Group (NCRIC), a Washington, D.C.-based medical professional liability insurer in a stock-for-stock transaction. The acquisition of NCRIC solidified ProAssurance’s market position in the mid-Atlantic states, and provided additional personnel and local expertise to drive growth in that region. We issued approximately 1.7 million shares valued at $67.1 million for purposes of this transaction. See Note 2 of our Consolidated Financial Statements included herein for more information regarding the transaction with NCRIC.
In 2005 ProAssurance announced the sale of its personal lines subsidiary MEEMIC Insurance Company and MEEMIC Agency (the MEEMIC Companies), which provide automobile, homeowners and associated coverage to educators and their families in Michigan. MEEMIC was sold to Motors Insurance Corporation, a subsidiary of GMAC Insurance Holdings, Inc. (GMAC Insurance), effective on January 1, 2006. GMAC Insurance paid approximately $325 million in cash for the MEEMIC Companies. In addition to receiving cash from GMAC Insurance, we retained approximately $75 million of MEEMIC’s capital. The results of our former personal lines segment are presented as discontinued operations in this report. See Note 3 of our Consolidated Financial Statements included herein for more information regarding the transaction with Motors Insurance Corporation.
In April and May 2004, we received net proceeds of $44.9 million from the issuance of $46.4 million of trust preferred securities. These trust preferred securities have a 30-year maturity and are callable at par in December 2009. The interest rate on these securities adjusts quarterly to the 3-month London Interbank Offered Rate (LIBOR) plus 385 basis points. In our acquisition of NCRIC, we assumed its obligations in connection with $15.0 million of trust preferred securities issued in December 2002. These trust preferred securities have a 30-year maturity and are callable at par in December 2007. The interest rate on these securities adjusts quarterly to the 3-month LIBOR plus 400 basis points. Both sets of trust preferred securities were issued by specially-created business trusts created solely for the sole purpose of issuing the securities.

##### Table of Contents

In early July 2003 we received $104.6 million from the issuance of 3.9% Convertible Debentures, due June 2023, having a face value of $107.6 million. We utilized a substantial portion of the net proceeds from the sale of the Convertible Debentures to repay our outstanding term loan. We are using the balance of the net proceeds from the sale of the Convertible Debentures and the trust preferred securities, for general corporate purposes, including contributions to the capital of our insurance subsidiaries to support the growth in insurance operations. See Note 10 to our Consolidated Financial Statements for more information regarding the Convertible Debentures and the trust preferred securities.
In the fourth quarter of 2002 ProAssurance sold 3,025,000 shares of common stock at a price of $16.55 per share in an underwritten public offering. ProAssurance received net proceeds from the offering in the amount of approximately $46.5 million. ProAssurance used the proceeds from the offering to support the growth of the professional liability insurance business and for general corporate purposes.
Proposed Transaction
On December 8, 2005 ProAssurance Corporation announced that it had signed a definitive agreement that will merge Physicians Insurance Company of Wisconsin, Inc. into a subsidiary of ProAssurance in an all stock transaction. We will issue shares of our common stock having a total value of approximately $100 million. ProAssurance has filed a Registration Statement on Form S-4 to register the shares to be issued in this transaction (SEC File Number 133-131874), which includes detailed information regarding this transaction.
Physicians Insurance Company of Wisconsin, Inc. is a Wisconsin-domiciled stock insurance company; its shares are not registered under the Securities Exchange Act of 1934. The transaction must be approved by Physicians Insurance Company of Wisconsin, Inc. shareholders, and is subject to required regulatory approvals.
Products and Services
We sell professional liability insurance primarily to physicians, dentists, other healthcare providers and healthcare facilities, principally in the mid-Atlantic, Midwest and Southeast. We have a small book of legal professional liability business in the Midwest as well. We are licensed to do business in every state but Connecticut, Maine, New Hampshire, New York and Vermont.
Although we generate a majority of our premiums from individual and small group practices, we also insure major physician groups as well as hospitals. While most of our business is written in the standard market, our subsidiary, Red Mountain Casualty Insurance Company, Inc., offers medical professional liability insurance on an excess and surplus lines basis. We also offer professional office package and workers’ compensation insurance products in connection with our medical professional liability products.
Marketing
We believe our size, financial strength and flexibility of distribution differentiates us from our competitors.
We utilize direct marketing and independent agents to write our business. In Alabama, we rely solely on direct marketing, and in Florida and Missouri, direct marketing accounts for a majority of our business. We use independent agents to market our professional liability insurance products in other markets. For the year ended December 31, 2005, we estimate that approximately 65% of our gross premiums written were produced through independent insurance agencies. These local agencies usually have one to three producers who specialize in professional liability insurance and who we believe are able to convey the factors that differentiate our professional liability insurance product. No single agent or agency accounts for more than 10% of our total direct premiums written.
Our marketing is primarily directed to physicians. We generally do not target large physician groups or facilities because of the difficulty in underwriting the individual risks and because their purchasing decision is more focused on price. Our marketing emphasizes:

##### Table of Contents

| – |  | excellent claims service and the other services and communications we provide to our customers,
| – |  | the sponsorship of risk management education seminars as an accredited provider of continuing medical education,
| – |  | risk management consultation, loss prevention seminars and other educational programs,
| – |  | legislative oversight and active support of proposed legislation we believe will have a positive effect on liability issues affecting the healthcare industry,
| – |  | the dissemination of newsletters and other printed material with information of interest to the healthcare industry, and
| – |  | endorsements by, and attendance at meetings of medical societies and related organizations.

These communications and services have helped us gain exposure among potential insureds and demonstrate our understanding of the insurance needs of the healthcare industry and promote a commonality of interest among us and our insureds.
Underwriting
Our underwriting process is driven by individual risk selection rather than by the size or other attributes of an account. Our pricing decisions are focused on achieving rate adequacy. We assess the quality and pricing of the risk, primarily emphasizing loss history, practice specialty and location in making our underwriting decision. Our underwriters work closely with our local claims departments. This includes consulting with staff about claims histories and patterns of practice in a particular locale as well as monitoring claims activity.
Our underwriting focuses on knowledge of local market conditions and the legal environment. Through our six regional underwriting offices located in Alabama, Florida, Indiana, Missouri, Michigan and Washington, D.C., we have established a local presence within our targeted markets to obtain better information more quickly.
Our underwriters work with our field marketing force to identify business that meets these established underwriting standards and to develop specific strategies to write the desired business. In performing this assessment, our underwriters may also consult with internal actuaries regarding loss trends and pricing and utilize loss-rating models to assess the projected underwriting results of certain insured risks.
These underwriters are also assisted by our local medical advisory committees that we have established in our key states. These committees are comprised of local physicians, dentists and representatives of hospitals and healthcare entities and help us maintain close ties to the medical communities in these states, provide information on the practice of medicine in each state and provide guidance on critical underwriting and claims issues.
Claims Management
We have claims offices in Alabama (2), Delaware, Florida (2), Illinois, Indiana, Kentucky, Michigan, Missouri, Ohio (2), Pennsylvania, Virginia, Washington, D.C., and West Virginia so that we can provide localized and timely attention to claims. Our claims department investigates the circumstances surrounding a medical incident from which a covered claim arises against an insured. As we investigate, our claims department establishes the appropriate case reserves for each claim and monitors the level of each case reserve as circumstances require.
Upon investigation, and in consultation with the insured and appropriate experts, we evaluate the merit of the claim and either seek reasonable settlement or aggressively defend the claim. If the claim is defended, our claims department manages the case, including selecting defense attorneys who specialize in medical liability cases, planning the defense and obtaining medical and/or other professional experts to assist in the analysis and defense of the claim. As part of this evaluation and preparation process we meet regularly with medical advisory committees in our key states to examine claims, attempt to identify potentially troubling practice patterns and make recommendations to our staff.

##### Table of Contents

We aggressively defend claims against our insureds that we believe have no merit or those we believe cannot be reasonably settled. As a result of this policy, many of our claims are litigated, and we engage experienced trial attorneys in each venue to handle the litigation in defense of our policyholders.
Our aggressive claims management approach generally results in increased loss adjustment expenses compared to those of other property and casualty lines or other companies specializing in professional liability insurance. However, we believe that our approach contributes to lower overall loss costs and results in greater customer loyalty. The success of this claims philosophy is based on our ability to develop relationships with attorneys who have significant experience in the defense of professional liability claims and who are able to defend claims in an aggressive, cost-efficient manner.
Investments
Our assets are held mainly in the operating insurance companies, but are overseen by executives in our holding company to ensure that we apply a consistent management strategy to the entire portfolio.
Our overall investment strategy is to focus on maximizing current income from our investment portfolio while maintaining safety, liquidity, duration and portfolio diversification. The portfolio is generally managed by professional third party asset managers whose results are evaluated periodically by management. The asset managers typically have the authority to make investment decisions, subject to investment policies, within the asset class they are responsible for managing. See Note 4 to our Consolidated Financial Statements for more detail on our investments.
Rating Agencies
Our claims-paying ability and financial strength are regularly evaluated and rated by three major rating agencies, A. M. Best, Fitch and Standard & Poor’s. In developing their ratings, these agencies evaluate an insurer’s ability to meet its obligations to policyholders. While these issues may be of concern to shareholders, these are not ratings of securities nor a recommendation to buy, hold or sell any security.
The following table presents the ratings of our group and our active insurance companies as of March 1, 2006:

The rating process is dynamic and ratings can change. If you are seeking updated information about our ratings, please visit the rating agency websites listed in the table.
Competition
Competition depends on several factors including pricing, size, name recognition, service quality, market commitment, breadth and flexibility of coverage, method of sale, financial stability and ratings assigned by A.M. Best, Standard & Poor’s, and Fitch. Many of these factors, such as market conditions, the ratings assigned by rating agencies, and regulatory conditions are beyond our control. However, for those factors within our control, such as service quality, market

commitment, financial strength and stability, we believe we have competitive strengths that make us a viable competitor in those states where we are currently writing insurance.
We compete with many insurance companies and alternative insurance mechanisms such as Risk Retention Groups or self-insuring entities. Many of the competitors concentrate on a single state and have an extensive knowledge of the local markets. We also compete with several large national insurers that may have greater financial strength and resources than we do.
We believe that we have a competitive advantage in the current market due to our size, geographic scope and name recognition, as well as our heritage as a policyholder-founded company with a long-term commitment to the professional liability insurance industry. We have achieved these advantages through our balance sheet strength, claims defense expertise, strong ratings and ability to deliver a high level of service to our insureds and agents. We believe that these competitive strengths make us a viable competitor in the states where we are currently writing insurance.
Beginning in 1999, insurance companies focused on medical professional liability coverage experienced higher claim costs on business written in prior years than they had reserved for initially. In many cases this resulted in significant losses and reduced the capital available to support current and future business. This led many professional liability carriers focused on medical professional liability coverages to withdraw from, or limit new business in, one or more markets.
In 2002 several medical liability insurance companies were forced from the market due to financial difficulties. The St. Paul Companies, then the leading writer of medical professional liability insurance, withdrew from the market. In 2003 Farmers Insurance Company exited medical professional liability insurance and The Reciprocal of America was placed under regulatory supervision. We believe these events have heightened the sensitivity of our target market to financial strength and stability.
From mid-2004 through 2005 several small competitors with limited capital have entered different states within our business footprint. These smaller companies tend to focus on limited pools of risk or geographic areas, but generally try to gain market share through lower premiums or less stringent underwriting. We have lost some of our business to the competitors, but our market position has largely allowed us to attract new customers to offset their departure.
In the latter half of 2005 we did see signs that established companies were beginning to compete primarily on price, or less stringent coverage terms. This has been isolated to more competitive markets where we maintain a strong market position, and we have been able to renew the vast majority of our policies at premium levels we believe will allow us to achieve our Return on Equity targets. However, should competitors become less disciplined in their pricing, or more permissive in their coverage terms, we would expect to lose the business of policyholders who based their buying decisions primarily on price. Our strategy is not to compete on price, but to demonstrate the value in the coverage we provide.
Insurance Regulatory Matters
We are subject to regulation under the insurance and insurance holding company statutes, of various jurisdictions including the domiciliary states of our insurance subsidiaries and other states in which our insurance subsidiaries do business. Our operating insurance subsidiaries are domiciled in Michigan, Alabama and Washington, D.C.
Insurance companies are also affected by a variety of state and federal legislative and regulatory measures and judicial decisions that define and qualify the risks and benefits for which insurance is sought and provided. These include redefinitions of risk exposure in such areas as medical liability, product liability, environmental damage and workers’ compensation. In addition, individual state insurance departments may prevent premium rates for some classes of insureds from reflecting the level of risk assumed by the insurer for those classes. Although there is limited federal regulation of the insurance business, each state has a comprehensive system for regulating insurers operating in that state. In addition, these insurance regulators periodically examine each insurer’s financial condition, adherence to statutory accounting practices, and compliance with insurance department rules and regulations.

##### Table of Contents

Our operating subsidiaries are required to file detailed annual reports with the state insurance regulators in each of the states in which they do business. The laws of the various states establish supervisory agencies with broad authority to regulate, among other things, licenses to transact business, premium rates for certain types of coverage, trade practices, agent licensing, policy forms, underwriting and claims practices, reserve adequacy, transactions with affiliates, and insurer solvency. Many states also regulate investment activities on the basis of quality, distribution and other quantitative criteria. States have also enacted legislation regulating insurance holding company systems, including acquisitions, the payment of dividends, the terms of affiliate transactions, and other related matters.
Applicable state insurance laws, rather than federal bankruptcy laws, apply to the liquidation or reorganization of insurance companies.
Insurance Regulation Concerning Change or Acquisition of Control
The insurance regulatory codes in our operating subsidiaries’ respective domiciliary states each contain similar provisions (subject to certain variations) to the effect that the acquisition of “control” of a domestic insurer or of any person that directly or indirectly controls a domestic insurer cannot be consummated without the prior approval of the domiciliary insurance regulator. In general, a presumption of “control” arises from the direct or indirect ownership, control or possession with the power to vote or possession of proxies with respect to 10% (5% in Alabama) or more of the voting securities of a domestic insurer or of a person that controls a domestic insurer. A person seeking to acquire control, directly or indirectly, of a domestic insurance company or of any person controlling a domestic insurance company must generally file an application for approval of the proposed change of control with the relevant insurance regulatory authority.
In addition, certain state insurance laws contain provisions that require pre-acquisition notification to state agencies of a change in control of a non-domestic insurance company admitted in that state. While such pre-acquisition notification statutes do not authorize the state agency to disapprove the change of control, such statutes do authorize certain remedies, including the issuance of a cease and desist order with respect to the non-domestic admitted insurers doing business in the state if certain conditions exist, such as undue market concentration.
Statutory Accounting and Reporting
Insurance companies are required to file detailed annual reports with the state insurance regulators in each of the states in which they do business, and their business and accounts are subject to examination by such regulators at any time. The financial information in these reports is prepared in accordance with Statutory Accounting Practices (SAP). Insurance regulators periodically examine each insurer’s financial condition, adherence to SAP, and compliance with insurance department rules and regulations.
Regulation of Dividends and Other Payments from Our Operating Subsidiaries
We are a legal entity separate and distinct from our subsidiaries. As a holding company with no other business operations, our primary sources of cash to meet our obligations, including principal and interest payments with respect to indebtedness, are available dividends and other statutorily permitted payments, such as tax allocation payments from our operating subsidiaries.
Our operating subsidiaries are subject to various state statutory and regulatory restrictions, applicable generally to any insurance company in its state of domicile, which limit the amount of dividends or distributions an insurance company may pay to its stockholders without prior regulatory approval. The restrictions are generally based on certain levels or percentages of surplus, investment income and operating income, as determined in accordance with SAP. Generally, dividends may be paid only out of earned surplus. In every case, surplus subsequent to the payment of any dividends must be reasonable in relation to an insurance company’s outstanding liabilities and must be adequate to meet its financial needs.

##### Table of Contents

State insurance holding company acts generally require domestic insurers to obtain prior approval of extraordinary dividends. Under the insurance holding company acts governing our principal operating subsidiaries, a dividend is considered to be extraordinary if the combined dividends and distributions to the parent holding company in any 12 month period are more than the greater of either the insurer’s net income for the prior fiscal year or 10% of its surplus at the end of the prior fiscal year. If insurance regulators determine that payment of a dividend or any other payments to an affiliate (such as payments under a tax-sharing agreement or payments for employee or other services) would, because of the financial condition of the paying insurance company or otherwise, be a detriment to such insurance company’s policyholders, the regulators may prohibit such payments that would otherwise be permitted without prior approval.
Risk-Based Capital
In order to enhance the regulation of insurer solvency, the National Association of Insurance Commissioners (NAIC) specifies risk-based capital (RBC) requirements for property and casualty insurance companies. At December 31, 2005, all of ProAssurance’s insurance subsidiaries exceeded the minimum level and, as a result, no regulatory response or action was required.
Investment Regulation
Our operating subsidiaries are subject to state laws and regulations that require diversification of investment portfolios and that limit the amount of investments in certain investment categories. Failure to comply with these laws and regulations may cause non-conforming investments to be treated as non-admitted assets for purposes of measuring statutory surplus and, in some instances, would require divestiture. We believe that our operating subsidiaries are in compliance with state investment regulations.
Guaranty Funds
Admitted insurance companies are required to be members of guaranty associations which administer state Guaranty Funds. These associations levy assessments (up to prescribed limits) on all member insurers in a particular state on the basis of the proportionate share of the premiums written by member insurers in the covered lines of business in that state. Maximum assessments permitted by law in any one year generally vary between 1% and 2% of annual premiums written by a member in that state. Some states permit member insurers to recover assessments paid through surcharges on policyholders or through full or partial premium tax offsets, while other states permit recovery of assessments through the rate filing process.
Shared Markets
State insurance regulations may force us to participate in mandatory property and casualty shared market mechanisms or pooling arrangements that provide certain insurance coverage to individuals or other entities that are otherwise unable to purchase such coverage in the commercial insurance marketplace. Our operating subsidiaries’ participation in such shared markets or pooling mechanisms is not material to our business at this time.
Legislative and Regulatory Changes
In recent years, the insurance industry has been subject to increased scrutiny by regulators and legislators. The NAIC and a number of state legislatures have considered or adopted legislative proposals that alter and, in many cases, increase the authority of state agencies to regulate insurance companies and insurance holding company systems.
Several of the states in which we operate, notably Florida, Illinois, Missouri, Ohio and West Virginia, have passed Tort Reform, but these laws have yet to materially affect our business. Recent court decisions in West Virginia have struck down the Tort Reforms enacted in 1991 and we believe there will be court challenges in the remaining states in the coming years. History tells us that many of these laws will be invalidated in the appeals process. Because we

12

##### Table of Contents

cannot predict with any certainty how appellate courts will rule on these laws we do not take them into account in our rate-making assumptions, except in Florida where such credit is required by law.
Legislatures in other states in which we operate are currently considering, or being asked to consider Tort Reform, but we cannot predict in which states those efforts will be successful. In certain states, Tort Reform may also place limits on the ability of medical liability insurers to raise or maintain rates at adequate levels. We continue to monitor developments on a state-by-state basis, and make business decisions accordingly.
The professional liability market in Florida is subject to three constitutional amendments that were approved by voters in November 2004. The first amendment places limits on fees plaintiff attorneys may collect in medical liability cases, but lawyers have been successful in evading these restrictions by having plaintiffs waive their constitutional rights to this protection. This practice has been challenged, but initial court rulings seem likely to permit it to continue. Therefore, we do not believe this law will result in fewer malpractice claims being filed.
The second amendment would take away the license of any physician who has three malpractice judgments or adverse findings by a licensing review organization. We believe this could cause physicians to demand settlements in malpractice cases which could generate more lawsuits and drive up costs. The Florida legislature has passed enabling legislation that prohibits retroactive application of this law. Thus only incidents occurring on or after November 4, 2004 are covered, and it’s likely to be at least five years in the future before the effects of this law could be felt.
The third amendment gives the public greater rights to see previously confidential state complaints filed against doctors and institutions, incident reports filed after medical errors, and documents from error reviews done by hospitals. Court challenges to this law are continuing, but if upheld, this could have a detrimental effect on peer review activities
There are also Tort Reform proposals being considered at the Federal level. This legislation has the backing of the Bush administration and passed the House of Representatives again in 2005. The legislation has never been approved in the Senate and while there are more Republicans now serving in the Senate, we do not believe there are enough votes to enact these reforms. As in the states, passage of a federal Tort Reform package would likely be subject to judicial challenge and we cannot be certain that it would be upheld by the courts.
In addition, prior to 2005 several committees of Congress made inquiries and conducted hearings as part of a broad study on the regulation of insurance companies, and legislation has been introduced in several of the past sessions of Congress which, if enacted, could result in the federal government assuming some role in the regulation of the insurance industry. While we do not have any reason to believe this legislation is likely to pass in the coming year, we cannot rule out that possibility.
Although the federal government does not regulate the business of insurance directly, federal initiatives often affect the insurance business. Current and proposed federal measures that may significantly affect the insurance business include changes in medical patient protection laws such as the “Patients Bill of Rights”, Tort Reform and environmental laws.
Employees
At December 31, 2005, we employed 517 persons in our continuing operations. None of our employees are represented by a labor union. We consider our employee relations to be good.
ITEM 1A. RISK FACTORS.
There are a number of factors, many beyond our control, which may cause results to differ significantly from our expectations. Some of these factors are described below under “Risk Factors,” while others having to do with operational, liquidity, interest rate and other variables, are described elsewhere in this report (see, for example, Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, “Liquidity and Capital Resources and Financial Condition” and Part II, Item 7A. Quantitative and Qualitative Disclosures about

13

##### Table of Contents

Market Risk). Any factor described in this report could by itself, or together with one or more factors, have a negative effect on our business, results of operations and/or financial condition. There may be factors not described in this report that could also cause results to differ from our expectations.
Our operating results may be affected if actual insured losses differ from our loss reserves.
Significant periods of time often elapse between the occurrence of an insured loss, the reporting of the loss by the insured and payment of that loss. To recognize liabilities for unpaid losses, we establish reserves as balance sheet liabilities representing estimates of amounts needed to pay reported and unreported losses and the related loss adjustment expense. The process of estimating loss reserves is a difficult and complex exercise involving many variables and subjective judgments. As part of the reserving process, we review historical data and consider the impact of various factors such as:

| – |  | trends in claim frequency and severity;
| – |  | changes in operations;
| – |  | emerging economic and social trends;
| – |  | inflation; and
| – |  | changes in the regulatory and litigation environments.

This process assumes that past experience, adjusted for the effects of current developments and anticipated trends, is an appropriate, but not necessarily accurate, basis for predicting future events. There is no precise method for evaluating the impact of any specific factor on the adequacy of reserves, and actual results are likely to differ from original estimates.
Our loss reserves also may be affected by court decisions that expand liability on our policies after they have been issued and priced. In addition, a significant jury award, or series of awards, against one or more of our insureds could require us to pay large sums of money in excess of our reserved amounts. Our policy to aggressively litigate claims against our insureds may increase the risk that we may be required to make such payments.
To the extent loss reserves prove to be inadequate in the future, we would need to increase our loss reserves and incur a charge to earnings in the period the reserves are increased, which could have a material adverse impact on our financial condition and results of operation and the price of our common stock.
If we are unable to maintain a favorable financial strength rating, it may be more difficult for us to write new business or renew our existing business.
Independent rating agencies assess and rate the claims-paying ability of insurers based upon criteria established by the agencies. Periodically the rating agencies evaluate us to confirm that we continue to meet the criteria of previously assigned ratings. The financial strength ratings assigned by rating agencies to insurance companies represent independent opinions of financial strength and ability to meet policyholder obligations and are not directed toward the protection of investors. Ratings by rating agencies are not ratings of securities or recommendations to buy, hold or sell any security.
Our principal operating subsidiaries hold favorable financial strength ratings with A.M. Best, Standard & Poor’s, Fitch and other rating agencies. Financial strength ratings are used by agents and customers as an important means of assessing the financial strength and quality of insurers. If our financial position deteriorates, we may not maintain our favorable financial strength ratings from the rating agencies. A downgrade or withdrawal of any such rating could limit or prevent us from writing desirable business.

We operate in a highly competitive environment.
The property and casualty insurance business is highly competitive. We compete with large national property and casualty insurance companies, locally-based specialty companies, self-insured entities and alternative risk transfer arrangements (such as captive insurers and risk retention groups) whose activities are directed to limited markets. Competitors include companies that have substantially greater financial resources than we do, as well as mutual companies and similar companies not owned by shareholders whose return on equity objectives may be lower than ours.
Competition in the property and casualty insurance business is based on many factors, including premiums charged and other terms and conditions of coverage, services provided, financial ratings assigned by independent rating agencies, claims services, reputation, perceived financial strength and the experience of the insurance company in the line of insurance to be written. Increased competition could adversely affect our ability to attract and retain business at current premium levels and reduce the profits that would otherwise arise from operations.
Our revenues may fluctuate with insurance market conditions.
We derive a significant portion of our insurance premium revenue from medical malpractice risks. Between 2000 and 2004, premium rates increased significantly which has improved our operating results. We believe competition has increased in the medical malpractice industry with the recent increases in premium rates. Should our competitors become less disciplined in their pricing, or more permissive in their terms, we may lose customers who base their purchasing decisions primarily on price because our policy is to charge adequate premiums on risks that meet our underwriting standards. We cannot predict whether, when or how market conditions will change, or the manner in which, or the extent to which any such changes may adversely impact the results of our operations.
Our revenues may fluctuate with interest rates and investment results.
We generally rely on the positive performance of our investment portfolio to offset insurance losses and to contribute to our profitability. As our investment portfolio is primarily comprised of interest-earning assets, prevailing economic conditions, particularly changes in market interest rates, may significantly affect our operating results. Changes in interest rates also can affect the value of our interest-earning assets, which are principally comprised of fixed and adjustable-rate investment securities. Generally, the values of fixed-rate investment securities fluctuate inversely with changes in interest rates. Interest rate fluctuations could adversely affect our stockholders’ equity, income and/or cash flows. Our total investments at December 31, 2005 were $2.631 billion, of which $2.403 billion was invested in fixed maturities. Unrealized pre-tax net investment losses on investments in fixed maturities were $15.2 million at December 31, 2005.
At December 31, 2005, we held equity investments having a fair value of $10.0 million in an available-for-sale portfolio and held additional equity securities having a fair value of $5.2 million in a trading portfolio. The fair value of these securities fluctuates depending upon company specific and general market conditions. Any decline in the fair value of available-for-sale securities that we determine to be other-than-temporary will reduce our net income. Any changes in the fair values of trading securities, whether gains or losses, will be included in net income in the period changed.
Changes in healthcare could have a material impact on our operations.
We derive substantially all of our medical professional liability insurance premiums from physicians and other individual healthcare providers, physician groups and smaller healthcare facilities. Significant attention has been focused on reforming the healthcare industry at both the federal and state levels which could result in changes to how health care providers insure their medical malpractice risks. A broad range of healthcare reform measures has been suggested, and public discussion of such measures will likely continue in the future. Proposals have included, among others, spending limits, price controls, limiting increases in insurance premiums, limiting

15

##### Table of Contents

the liability of doctors and hospitals for tort claims, imposing liability on institutions rather than physicians, and restructuring the healthcare insurance system. We cannot predict which, if any, reform proposals will be adopted, when they may be adopted or what impact they may have on us. The adoption of certain of these proposals could materially adversely affect our financial condition or results of operations.
In addition to regulatory and legislative efforts, there have been significant market driven changes in the healthcare environment. In recent years, a number of factors related to the emergence of managed care have negatively impacted or threatened to impact the medical practice and economic independence of medical professionals. Medical professionals have found it more difficult to conduct a traditional fee-for-service practice and many have been driven to join or contractually affiliate with larger organizations. Such change and consolidation may result in the elimination of, or a significant decrease in, the role of the physician in the medical malpractice insurance purchasing decision. It could also result in greater emphasis on the role of professional managers, who may seek to purchase insurance on a price competitive basis, and who may favor insurance companies that are larger and more highly rated than we are. In addition, such change and consolidation could reduce our medical malpractice premiums as groups of insurance purchasers generally retain more risk or self insure.
The movement from traditional fee-for-service practice to the managed care environment may also result in an increase in the liability profile of our insureds. The majority of our insured physicians practice in primary care specialties such as internal medicine, family practice, general practice and pediatrics. In the managed care environment, these primary care physicians are being required to take on the role of “gatekeeper” and restrain the use of specialty care by controlling access to specialists and by performing certain procedures that would customarily be performed by specialists in a fee-for-service setting. These practice changes may result in an increase in the claims frequency and severity experienced by primary care physicians and by us as their insurance carrier.
We are a holding company and are dependent on dividends and other payments from our operating subsidiaries, which are subject to dividend restrictions.
We are a holding company whose principal source of funds is cash dividends and other permitted payments from operating subsidiaries. If our subsidiaries are unable to make payments to us, or are able to pay only limited amounts, we may be unable to make payments on our indebtedness. The payment of dividends by these operating subsidiaries is subject to restrictions set forth in the insurance laws and regulations of their respective states of domicile, as discussed under Item 1, “Insurance Regulatory Matters” on page 10.

16

##### Table of Contents

Regulatory requirements could have a material impact on our operations.
Our insurance businesses are subject to extensive regulation by state insurance authorities in each state in which they operate. Regulation is intended for the benefit of policyholders rather than shareholders. In addition to the amount of dividends and other payments that can be made to a holding company by insurance subsidiaries, these regulatory authorities have broad administrative and supervisory power relating to:

| – |  | licensing requirements;
| – |  | trade practices;
| – |  | capital and surplus requirements;
| – |  | investment practices; and
| – |  | rates charged to insurance customers.

These regulations may impede or impose burdensome conditions on rate increases or other actions that we may want to take to enhance our operating results. In addition, we may incur significant costs in the course of complying with regulatory requirements. Most states also regulate insurance holding companies like us in a variety of matters such as acquisitions, changes of control and the terms of affiliated transactions.
Future legislative or regulatory changes may also adversely affect our business operations.
The unpredictability of court decisions could have a material impact on our operations.
The financial position of our insurance subsidiaries may also be affected by court decisions that expand insurance coverage beyond the intention of the insurer at the time it originally issued an insurance policy. In addition, a significant jury award, or series of awards, against one or more of our insureds could require us to pay large sums of money in excess of our reserve amounts.
The passage of tort reform or other legislation, and the subsequent review of such laws by the courts could have a material impact on our operations.
Tort reforms generally restrict the ability of a plaintiff to recover damages by, among other limitations, eliminating certain claims that may be heard in a court, limiting the amount or types of damages, changing statutes of limitation or the period of time to make a claim, and limiting venue or court selection. A number of states in which we do business have enacted, or are considering, tort reform legislation. Proposed federal tort reform legislation has failed to win Congressional approval to date.
While the effects of tort reform would appear to be beneficial to our business generally, there can be no assurance that such reforms will be effective or ultimately upheld by the courts in the various states. Further, if tort reforms are effective, the business of providing professional liability insurance may become more attractive, thereby causing an increase in competition for us.
In addition, there can be no assurance that the benefits of tort reform will not be accompanied by legislation or regulatory actions that may be detrimental to our business. For example, various states have established or are evaluating their intention to establish state sponsored malpractice insurance for their resident physicians that may eliminate targeted physicians from the private insurance market. Furthermore, insurance regulatory authorities may require premium rate limitations and expanded coverage requirements as well as other requirements in anticipation of the expected benefits of tort reform which may or may not be actually realized.
Our geographic concentration ties our performance to the economic, regulatory and demographic conditions of the mid-Atlantic, Midwest and Southeast states.
Our revenues and profitability are subject to prevailing economic, regulatory, demographic and other conditions in the states in which we write insurance. We currently write professional liability insurance in 22 states and the District of Columbia, with approximately 68% of gross premiums written in Alabama, Florida, Indiana, Michigan and Ohio in 2005. Because our business currently is concentrated in a limited number of markets, adverse developments that are

17

##### Table of Contents

limited to a geographic area in which we do business may have a disproportionately greater affect on us than they would have if we did business in markets outside that particular geographic area.
Our business could be adversely affected by the loss of independent agents.
We depend in part on the services of independent agents and brokers in the marketing of our insurance products. We face competition from other insurance companies for the services and allegiance of independent agents and brokers. These agents and brokers may choose to direct business to competing insurance companies or may direct less desirable risks to us.
If market conditions cause reinsurance to be more costly or unavailable, we may be required to bear increased risks or reduce the level of our underwriting commitments.
As part of our overall risk and capacity management strategy, we purchase reinsurance for significant amounts of risk underwritten by our insurance company subsidiaries. Market conditions beyond our control determine the availability and cost of the reinsurance, which may affect the level of our business and profitability. We may be unable to maintain current reinsurance coverage or to obtain other reinsurance coverage in adequate amounts and at favorable rates. If we are unable to renew our expiring coverage or to obtain new reinsurance coverage, either our net exposure to risk would increase or, if we are unwilling to bear an increase in net risk exposures, we would have to reduce the amount of our underwritten risk.
We cannot guarantee that our reinsurers will pay in a timely fashion, if at all, and, as a result, we could experience losses.
We transfer some of our risks to reinsurance companies in exchange for part of the premium we receive in connection with the risk. Although reinsurance makes the reinsurer liable to us to the extent the risk is transferred, it does not relieve us of our liability to our policyholders. If reinsurers fail to pay us or fail to pay on a timely basis, our financial results would be adversely affected. At December 31, 2005, we had reinsurance recoverables on paid and unpaid losses and loss adjustment expenses of approximately $327.7 million.
The guaranty fund assessments that we are required to pay to state guaranty associations may increase and results of operations and financial condition could suffer as a result.
Each state in which we operate has separate insurance guaranty fund laws requiring admitted property and casualty insurance companies doing business within their respective jurisdictions to be members of their guaranty associations. These associations are organized to pay covered claims (as defined and limited by the various guaranty association statutes) under insurance policies issued by insolvent insurance companies. Most guaranty association laws enable the associations to make assessments against member insurers to obtain funds to pay covered claims after a member insurer becomes insolvent. These associations levy assessments (up to prescribed limits) on all member insurers in a particular state on the basis of the proportionate share of the premiums written by member insurers in the covered lines of business in that state. Maximum assessments permitted by law in any one year generally vary between 1% and 2% of annual premiums written by a member in that state. Some states permit member insurers to recover assessments paid through surcharges on policyholders or through full or partial premium tax offsets, while other states permit recovery of assessments through the rate filing process.
Property and casualty guaranty fund assessments incurred by us totaled $226,000 and $396,000 for 2005 and 2004, respectively. Our policy is to accrue the insurance insolvencies when notified of assessments. We are not able to reasonably estimate the liabilities of an insolvent insurer or develop a meaningful range of the insolvent insurer’s liabilities because of inadequate financial data with respect to the estate of the insolvent company as supplied by the guaranty funds.

Our business could be adversely affected by the loss of one or more key employees.
We are heavily dependent upon our senior management and the loss of services of our senior executives could adversely affect our business. Our success has been, and will continue to be, dependent on our ability to retain the services of existing key employees and to attract and retain additional qualified personnel in the future. The loss of the services of key employees or senior managers, or the inability to identify, hire and retain other highly qualified personnel in the future, could adversely affect the quality and profitability of our business operations.
Our board of directors is in the process of considering succession planning relating to our Chief Executive Officer. Dr. Crowe, our current Chairman and Chief Executive Officer, has indicated to the board that he has no immediate plans for retirement.
Provisions in our charter documents, Delaware law and state insurance law may impede attempts to replace or remove management or impede a takeover, which could adversely affect the value of our common stock.
Our certificate of incorporation, bylaws and Delaware law contain provisions that may have the effect of inhibiting a non-negotiated merger or other business combination. Additionally, the board of directors may issue preferred stock, which could be used as an anti-takeover device, without a further vote of our stockholders. We currently have no preferred stock outstanding, and no present intention to issue any shares of preferred stock. However, because the rights and preferences of any series of preferred stock may be set by the board of directors in its sole discretion, the rights and preferences of any such preferred stock may be superior to those of our common stock and thus may adversely affect the rights of the holders of common stock.
The voting structure of common stock and other provisions of our certificate of incorporation are intended to encourage a person interested in acquiring us to negotiate with, and to obtain the approval of, the board of directors in connection with a transaction. However, certain of these provisions may discourage our future acquisition, including an acquisition in which stockholders might otherwise receive a premium for their shares. As a result, stockholders who might desire to participate in such a transaction may not have the opportunity to do so.
In addition, state insurance laws provide that no person or entity may directly or indirectly acquire control of an insurance company unless that person or entity has received approval from the insurance regulator. An acquisition of control of our insurance operating subsidiaries generally would be presumed if any person or entity acquires 10% (5% in Alabama) or more of its outstanding common stock, unless the applicable insurance regulator determines otherwise.
These provisions apply even if the offer may be considered beneficial by stockholders.
If a change in management or a change of control is delayed or prevented, the market price of our common stock could decline.

GLOSSARY OF SELECTED INSURANCE AND RELATED FINANCIAL TERMS
In an effort to help our investors and other interested parties better understand our report, we are providing a Glossary of Selected Insurance Terms. These definitions are taken from recognized industry sources such as A. M. Best and The Insurance Information Institute. This list is intended to be informative and explanatory, but we do not represent that it is a comprehensive glossary.

Accident year |  | The accounting period in which an insured event becomes a liability of the insurer.
Admitted company; admitted basis |  | An insurance company licensed and authorized to do business in a particular state. An admitted company doing business in a state is said to operate on “an admitted basis” and is subject to all state insurance laws and regulations pertaining to its operations. (See: Non-admitted company)
Adverse selection |  | The tendency of those exposed to a higher risk to seek more insurance coverage than those at a lower risk. Insurers react either by charging higher premiums or not insuring at all, as in the case of floods. Adverse selection can be seen as concentrating risk instead of spreading it.
Agent |  | An individual or firm that represents an insurer under a contractual or employment agreement for the purpose of selling insurance. There are two types of agents: independent agents, who represent one or more insurance companies but are not employed by those companies and are paid on commission, and exclusive or captive agents, who by contract are required to represent or favor only one insurance company and are either salaried or work on commission. Insurance companies that use employee or captive agents are called direct writers. Agents are compensated by the insurance company whose products they sell. By definition, with respect to a given insurer, an agent is not a broker (See: Brokers)
Alternative markets |  | Mechanisms used to fund self-insurance. This includes captives, which are insurers owned by one or more non-insurers to provide owners with coverage. Risk-retention groups, formed by members of similar professions or businesses to obtain liability insurance, are also a form of self-insurance.
Assets; admitted; non-admitted |  | Property owned, in this case by an insurance company, including stocks, bonds, and real estate. Because insurance accounting is concerned with solvency and the ability to pay claims, insurance regulators require a conservative valuation of assets, prohibiting insurance companies from listing assets on their balance sheets whose values are uncertain, such as furniture, fixtures, debit balances, and accounts receivable that are more than 90 days past due (these are non-admitted assets). Admitted assets are those assets that can be easily sold in the event of liquidation or borrowed against, and receivables for which payment can be reasonably anticipated.

##### Table of Contents

Broker |  | An intermediary between a customer and an insurance company. Brokers typically search the market for coverage appropriate to their clients and they usually sell commercial, not personal, insurance. Brokers are compensated by the insureds on whose behalf they are working. With respect to a given insurer, a broker is not an agent. (See:
|  | Agent)
Bulk reserves |  | Reserves for losses that have occurred but have not been reported as well as anticipated changes to losses on reported claims. Bulk reserves are the difference between (i) the sum of case reserves and paid losses and (ii) an actuarially determined estimate of the total losses necessary for the ultimate settlement of all reported and incurred but not reported claims, including amounts already paid. (See: Case Reserves)
Capacity |  | For an individual insurer, the maximum amount of premium or risk it can underwrite based on its financial condition. The adequacy of an insurer’s capital relative to its exposure to loss is an important measure of solvency.
Capital |  | Stockholder’s equity (for publicly-traded insurance companies) and policyholders’ surplus (for mutual insurance companies). Capital adequacy is linked to the riskiness of an insurer’s business. (See:
|  | Risk-Based Capital, Surplus, Solvency)
Case reserves |  | Reserves for future losses for reported claims as established by an insurer’s claims department.
Casualty insurance |  | Insurance which is primarily concerned with the losses caused by injuries to third persons (in other words, persons other than the policyholder) and the legal liability imposed on the insured resulting therefrom. (See: Professional liability insurance, Medical professional liability insurance)
Catastrophe |  | Term used for statistical recording purposes to refer to a single incident or a series of closely related incidents causing severe insured property losses totaling more than a given amount.
Catastrophe reinsurance |  | Reinsurance (insurance for insurers) for catastrophic losses.
Cede, cedant; ceding company |  | When a party reinsures its liability with another, it “cedes” business and is referred to as the “cedant” or “ceding company.”
Claims-made policy; coverage |  | A form of insurance that pays claims presented to the insurer during the term of the policy or within a specific term after its expiration. It limits liability insurers’ exposure to unknown future liabilities. Under a claims-made policy, an insured event becomes a liability when the event is first reported to the insurer.
Combined ratio |  | The sum of the underwriting expense ratio and net loss ratio, determined in accordance with either statutory accounting principles (SAP) or GAAP.

23

##### Table of Contents

Commission |  | Fee paid to an agent or insurance salesperson as a percentage of the policy premium. The percentage varies widely depending on coverage, the insurer, and the marketing methods.
Direct premiums written |  | Premiums charged by an insurer for the policies that it underwrites, excluding any premiums that it receives as a reinsurer.
Direct writer(s) |  | Insurance companies that sell directly to the public using exclusive agents or their own employees.
Domestic insurance company |  | Term used by a state to refer to any company incorporated there.
Excess & Surplus Lines; Surplus lines |  | Property/casualty insurance coverage that isn’t generally available from insurers licensed in the state (See: Admitted companies) and must be purchased from a “non-admitted company”. Examples include risks of an unusual nature that require greater flexibility in policy terms and conditions than exist in standard forms or where the highest rates allowed by state regulators are considered inadequate by admitted companies. Laws governing surplus lines vary by state.
Excess coverage; excess limits |  | An insurance policy that provides coverage limits above another policy with similar coverage terms, or above a self-insured amount.
Extended Reporting Endorsement |  | Also known as a “tail policy” or “tail premium.” Tail coverage provides protection for future claims filed after a claims-made policy has lapsed. Typically requires payment of an additional premium, the “tail premium.” “Tail coverage” may also be granted if the insured becomes disabled, dies or permanently retired from the covered occupation (i.e., the practice of medicine in medical liability policies.)
Facultative reinsurance |  | A generic term describing reinsurance where the reinsurer assumes all or a portion of a single risk. Each risk is separately evaluated and each contract is separately negotiated by the reinsurer.
Frequency |  | Number of times a loss occurs per unit of risk or exposure. One of the criteria used in calculating premium rates.
Front, fronting |  | A procedure in which a primary insurer acts as the insurer of record by issuing a policy, but then passes all or virtually all of the risk to a reinsurer in exchange for a commission. Often, the fronting insurer is licensed to do business in a state or country where the risk is located, but the reinsurer is not. The reinsurer in this scenario is often a captive or an independent insurance company that cannot sell insurance directly in a particular country.
Gross premiums written |  | Total premiums for direct insurance written and assumed reinsurance during a given period. The sum of direct and assumed premiums written.

24

##### Table of Contents

Guaranty Fund; assessment(s) |  | The mechanism by which solvent insurers ensure that some of the policyholder and third party claims against insurance companies that fail are paid. Such funds are required in all 50 states, the District of Columbia and Puerto Rico, but the type and amount of claim covered by the fund varies from state to state.
Incurred but not reported (IBNR) |  | Actuarially estimated reserves for estimated losses that have been incurred by insureds and reinsureds but not yet reported to the insurer or reinsurer including unknown future developments on losses which are known to the insurer or reinsurer. Insurance companies regularly adjust reserves for such losses as new information becomes available.
Incurred losses |  | Losses covered by the insurer within a fixed period, whether or not adjusted or paid during the same period, plus changes in the estimated value of losses from prior periods.
Insolvent; insolvency |  | Insurer’s inability to pay debts. Typically the first sign of problems is inability to pass the financial tests regulators administer as a routine procedure. (See: Risk-based capital)
Investment income |  | Income generated by the investment of assets. Insurers have two sources of income, underwriting (premiums less claims and expenses) and investment income.
Liability insurance |  | A line of casualty insurance for amounts a policyholder is legally obligated to pay because of bodily injury or property damage caused to another person. (See: Casualty insurance, Professional liability insurance, Medical professional liability insurance)
Limits |  | Maximum amount of insurance that can be paid for a covered loss.
Long-tail; short-tail |  | The long period of time between collecting the premium for insuring a risk and the ultimate payment of losses. This allows insurance companies to invest the premiums until losses are paid, thus producing a higher level of invested assets and investment income as compared to other lines of property and casualty business. Medical professional liability is considered a long tail line of insurance. Personal lines is primarily considered a short tail line of insurance due to shorter time periods between insuring the risk and the ultimate payment of claims. As a result, there is less time to invest premiums collected, which makes it necessary to achieve an underwriting profit in order to generate a satisfactory return on equity. (See: Medical professional liability, Professional liability)
Loss adjustment expenses (LAE) |  | The expenses of settling claims, including legal and other fees and the portion of general expenses allocated to claim settlement costs.
Loss costs |  | The portion of an insurance rate used to cover claims and the costs of adjusting claims. Insurance

25

##### Table of Contents

|  | companies typically determine their rates by estimating their future loss costs and adding a provision for expenses, profit, and contingencies.
Loss ratio |  | Percentage of each premium dollar an insurer spends on claims.
Loss reserves |  | Liabilities established by insurers and reinsurers to reflect the estimated cost of claims payments and the related expenses that the insurer or reinsurer will ultimately be required to pay in respect of insurance or reinsurance it has written. They represent a liability on the insurer’s balance sheet.
Medical professional liability insurance |  | Insurance against the legal liability of an insured (and against loss, damage or expense incidental to a claim of such liability) arising out of death, injury or disablement of a person as the result of negligent deviation from the standard of care or other misconduct in rendering professional service.
NAIC |  | The National Association of Insurance Commissioners is the organization of insurance regulators from the 50 states, the District of Columbia and the four U.S. territories. The NAIC provides a forum for the development of uniform policy when uniformity is appropriate.
Net loss ratio |  | The net loss ratio measures the ratio of net losses to earned premiums determined in accordance with SAP or GAAP.
Net premium earned |  | The portion of net premium written that is recognized for accounting purposes as income during a particular period. Equal to net premiums written plus the change in net unearned premiums during the period.
Net premiums written |  | Gross premiums written for a given period less premiums ceded to reinsurers during such period.
Non-admitted company; basis |  | Insurers licensed in some states, but not others. States where an insurer is not licensed call that insurer “non-admitted.” Non-admitted companies sell coverage that is unavailable from licensed insurers within a state and are generally exempt from most state laws and regulations related to rates and coverages. Policyholders of such companies generally do not have the same degree of consumer protection and financial recourse as policyholders of admitted companies. Non-admitted companies are said to operate on a “non-admitted” basis.
Occurrence policy; coverage |  | Insurance that pays claims arising out of incidents that occur during the policy term, even if they are filed many years later. Under an occurrence policy the insured event becomes a liability when the event takes place.
Operating ratio |  | The operating ratio is the combined ratio, less the ratio of investment income (exclusive of realized gains and losses) to net earned premiums, if determined in accordance with GAAP. While the combined ratio

26

##### Table of Contents

|  | strictly measures underwriting profitability, the operating ratio incorporates the effect of investment income.
Policy |  | A written contract for insurance between an insurance company and policyholder stating details of coverage.
Premium |  | The price of an insurance policy, typically charged annually or semiannually.
Premiums written |  | The total premiums on all policies written by an insurer during a specified period of time, regardless of what portions have been earned.
Premium tax |  | A state tax on premiums for policies issued in the state, paid by insurers.
Primary Company |  | In a reinsurance transaction, the insurance company that is reinsured.
Professional liability insurance |  | Covers professionals for negligence and errors or omissions that cause injury or economic loss to their clients. (See: Casualty insurance, Liability insurance, Medical professional liability insurance)
Property/casualty insurance |  | Covers damage to or loss of policyholders’ property and legal liability for damages caused to other people or their property.
Rate |  | The cost of insurance for a specific unit of exposure, such as for one physician. Rates are based on historical loss experience for similar risks and may be regulated by state insurance offices.
Rating agencies |  | These agencies assess insurers’ financial strength and viability to meet claims obligations. Some of the factors considered include company earnings, capital adequacy, operating leverage, liquidity, investment performance, reinsurance programs, and management ability, integrity and experience. A high financial rating is not the same as a high consumer satisfaction rating.
Reinsurance |  | Insurance bought by insurance companies. In a reinsurance contract the reinsurer agrees to indemnify another insurance or reinsurance company, the ceding company, against all or a portion of the insurance or reinsurance risks underwritten by the ceding company under one or more policies. Reinsurers may have their own reinsurers, called retrocessionaires. Reinsurers don’t pay policyholder claims. Instead, they reimburse insurers for claims paid.
Reinsured layer; retained layer |  | The retained layer is the cumulative portion of each loss, on a per-claim basis, which is less than an insurer’s reinsurance retention for a given coverage year. Likewise, the reinsured layer is the cumulative portion of each loss that exceeds the reinsurance retention. (See:
|  | Reinsurance, Retention)
Reserves |  | A company’s best estimate of what it will pay, at some point in the future, for claims for which it is currently responsible.

27

##### Table of Contents

Retention |  | The amount or portion of risk that an insurer retains for its own account. Losses in excess of the retention level up to the outer limit, if any, are paid by the reinsurer. In proportional treaties, the retention may be a percentage of the original policy’s limit. In excess of loss business, the retention is a dollar amount of loss, a loss ratio or a percentage.
Return on Equity |  | Net Income (or if applicable, Income from Continuing Operations) divided by the average of beginning and ending stockholders’ equity. This ratio measures a company’s overall after-tax profitability from underwriting and investment activity and shows how efficiently invested capital is being used.
Risk-Based Capital (RBC) |  | A regulatory measure of the amount of capital required for an insurance company, based upon the volume and inherent riskiness of the insurance sold, the composition of its investment portfolio and other financial risk factors. Higher-risk types of insurance, liability as opposed to property business, generally necessitate higher levels of capital. The NAIC’s RBC model law stipulates four levels of regulatory action with the degree of regulatory intervention increasing as the level of surplus falls below a minimum amount as determined under the model law. (See: NAIC)
Risk management |  | Management of the varied risks to which a business firm or association might be subject. It includes analyzing all exposures to gauge the likelihood of loss and choosing options to better manage or minimize loss. These options typically include reducing and eliminating the risk with safety measures, buying insurance, and self-insurance.
Self-insurance |  | The concept of assuming a financial risk oneself, instead of paying an insurance company to take it on. Every policyholder is a self-insurer in terms of paying a deductible and co-payments. Larger policyholders often self-insure frequent or predictable losses to avoid insurance overhead expenses.
Severity |  | The average claim cost, statistically determined by dividing dollars of losses by the number of claims.
Solvent, solvency |  | Insurance companies’ ability to pay the claims of policyholders. Regulations to promote solvency include minimum capital and surplus requirements, statutory accounting conventions, limits to insurance company investment and corporate activities, financial ratio tests, and financial data disclosure.
Statutory Accounting Principles; SAP |  | More conservative standards than under GAAP accounting rules, they are imposed by state laws that emphasize the present solvency of insurance companies. SAP helps ensure that the company will have sufficient funds readily available to meet all anticipated insurance obligations by recognizing liabilities earlier or at a higher value than GAAP and assets later or at a lower value. For example, SAP

##### Table of Contents

|  | requires that selling expenses be recorded immediately rather than amortized over the life of the policy. (See: Generally Accepted Accounting Principles, Admitted assets)
Surplus; statutory surplus |  | The excess of admitted assets over total liabilities (including loss reserves) that protects policyholders in case of unexpectedly high claims. “Statutory Surplus” is determined in accordance with Statutory Accounting Principles.
Tail |  | The period of time that elapses between the occurrence of the loss event and the payment in respect thereof.
Third-party coverage |  | Liability coverage purchased by the policyholder as a protection against possible lawsuits filed by a third party. The insured and the insurer are the first and second parties to the insurance contract.
Treaty reinsurance |  | The reinsurance of a specified type or category of risks defined in a reinsurance agreement (a ''treaty’’) between a primary insurer or other reinsured and a reinsurer. Typically, in treaty reinsurance, the primary insurer or reinsured is obligated to offer and the reinsurer is obligated to accept a specified portion of all such type or category of risks originally written by the primary insurer or reinsured.
Underwriting |  | The insurer’s or reinsurer’s process of reviewing applications submitted for insurance coverage, deciding whether to accept all or part of the coverage requested and determining the applicable premiums.
Underwriting expense ratio |  | The ratio of underwriting, acquisition and other insurance expenses incurred to net premiums earned (for statutory purposes, the ratio of underwriting expenses incurred to net premiums written.)
Underwriting expenses |  | The aggregate of policy acquisition costs, including commissions, and the portion of administrative, general and other expenses attributable to underwriting operations.
Underwriting income; loss |  | The insurer’s profit on the insurance sale after all expenses and losses have been paid, before investment income or income taxes. When premiums aren’t sufficient to cover claims and expenses, the result is an “underwriting loss.”
Underwriting profit |  | The amount by which net earned premiums exceed Underwriting Income; the sum of losses, loss adjustment expenses and underwriting expenses (See: Underwriting Income)
Unearned premium |  | The portion of premium that represents the consideration for the assumption of risk in the future. Such premium is not yet earned since the risk has not yet been assumed. May also be defined as the pro-rata portion of written premiums that would be returned to policyholders if all policies were terminated by the insurer on a given date.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.
The following discussion should be read in conjunction with the Consolidated Financial Statements and Notes thereto accompanying this report. Throughout the discussion, references to ProAssurance, “we,” “us” and “our” refers to ProAssurance Corporation and its subsidiaries. The discussion contains certain forward-looking information that involves risks and uncertainties. As discussed under “Forward-Looking Statements” and “Risk Factors,” our actual financial condition and operating results could differ significantly from these forward-looking statements.
In late 2005 we reached an agreement to sell our personal lines operations. Accordingly, our Consolidated Financial Statements report our personal lines operations, which were formerly reported as a separate operating segment, as a component of discontinued operations in all periods presented.
Critical Accounting Policies
Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). Preparation of these financial statements requires us to make estimates and assumptions in certain circumstances that affect the amounts reported in our consolidated financial statements and related footnotes. We evaluate these estimates and assumptions on an on-going basis based on historical developments, market conditions, industry trends and other information that we believe to be reasonable under the circumstances. There can be no assurance that actual results will conform to our estimates and assumptions, and that reported results of operations will not be materially affected by changes in these estimates and assumptions.
Management considers the following accounting policies to be critical because they involve significant judgment by management and the effect of those judgments could result in a material effect on our financial statements.
Reserve for Losses and Loss Adjustment Expenses (reserve for losses or reserve)
Our reserve for losses represents our estimate of the future amounts necessary to pay claims and expenses associated with the settlement and investigation of claims. These estimates consist of case reserves and bulk reserves. The estimates take into consideration our past loss experience, available industry data and projections as to future claims frequency, severity, inflationary trends and settlement patterns. External actuaries review our reserve for losses each year. We consider the views of the external actuaries as well as other factors, such as known, anticipated or estimated changes in frequency and severity of claims and loss retention levels and premium rates, in establishing the amount of our reserve for losses. Estimating casualty insurance reserves, and particularly liability reserves, is a complex process. These claims are typically resolved over an extended period of time, often five years or more, and estimating loss costs for these claims requires multiple judgments involving many uncertainties. Our reserve estimates may vary significantly from the eventual outcome. The assumptions used in establishing our reserve for losses are regularly reviewed and updated by management as new data becomes available. Any adjustments necessary are reflected in then-current operations. Due to the size of our reserve for losses, even a small percentage adjustment to these estimates could have a material effect on our results of operations for the period in which the adjustment is made.
Reinsurance
Our receivable from reinsurers on unpaid losses and loss adjustment expenses represents our estimate of the amount of our reserve for losses that will be recoverable from our reinsurers. Our estimate is based upon our estimates of the ultimate losses that we expect to incur and the portion of those losses that we expect to be allocable to reinsurers based upon the terms of our reinsurance agreements. We also estimate premiums ceded under reinsurance agreements wherein the premium due to the reinsurer, subject to certain maximums and minimums, is based on losses reimbursed under the agreement. Our estimates of the amounts receivable from and payable to reinsurers are regularly reviewed and updated by management as new data becomes available. Given the uncertainty of the ultimate amounts of our losses, these estimates may vary significantly from the eventual outcome. Any adjustments necessary are reflected in then-current operations. Due to the size of our reinsurance balances, even a small adjustment

34

##### Table of Contents

to these estimates could have a material effect on our results of operations for the period in which the adjustment is made.
We evaluate each of our ceded reinsurance contracts at its inception to determine if there is sufficient risk transfer to allow the contract to be accounted for as reinsurance under current accounting guidance. At December 31, 2005 all ceded contracts are accounted for as risk transferring contracts.
Our assessment of the collectibility of the recorded amounts receivable from reinsurers considers both the payment history of the reinsurer and publicly available financial and rating agency data. At December 31, 2005 we believe all of our recorded reinsurance receivables to be collectible.
Investments
We consider our fixed maturity securities as available-for-sale and our equity securities as either available-for-sale or trading portfolio securities. Both available-for-sale and trading portfolio securities are carried at fair value. Changes in the market value (unrealized gains and losses) of available-for-sale securities, whether positive or negative, are included, net of the related tax effect, in accumulated other comprehensive income, a component of stockholders’ equity, and are excluded from current period net income. Positive and negative changes in the market value of trading portfolio securities are included in current period net income as a component of net realized investment gains (losses).
We evaluate the securities in our available-for-sale investment portfolio on at least a quarterly basis for declines in market value below cost for the purpose of determining whether these declines represent other than temporary declines. Some of the factors we consider in the evaluation of our investments are:

| – |  | the extent to which the market value of the security is less than its cost basis,
| – |  | the length of time for which the market value of the security has been less than its cost basis,
| – |  | the financial condition and near-term prospects of the security’s issuer, taking into consideration the economic prospects of the issuer’s industry and geographical region, to the extent that information is publicly available, and
| – |  | our ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value.

A decline in the fair value of an available-for-sale security below cost that we judge to be other than temporary is realized as a loss in the current period income statement and reduces the cost basis of the security. In subsequent periods, we base any measurement of gain or loss or decline in value upon the adjusted cost basis of the security.
Deferred Policy Acquisition Costs
Policy acquisition costs, primarily commissions, premium taxes and underwriting salaries, vary directly with, and are primarily related to, the acquisition of new and renewal premiums. Such costs are capitalized and charged to expense as the related premium revenue is recognized. We evaluate the recoverability of our deferred policy acquisition costs based on our estimates of the profitability of the underlying business and any amounts estimated to be unrecoverable are charged to expense in the current period.
Goodwill
In accordance with Statement of Financial Accounting Standards No. 142 “Goodwill and Other Intangible Assets” we make an annual assessment as to whether the value of our goodwill assets is impaired. We completed such assessments in 2005 and 2004 and concluded that the value of our goodwill assets related to continuing operations of approximately $29.5 million was not impaired. We use both market-based valuation models and a capital asset pricing model to estimate the fair value. These models require the use of numerous assumptions regarding market perceptions of value as related to our consolidated and reporting unit historical and projected operating results and those of other economically similar entities. Changes to these assumptions could significantly lower our estimates of fair value and result in a

35

##### Table of Contents

determination that goodwill has suffered impairment in value. Any determined impairment would be reflected as an expense in the period identified.
Overview
We are an insurance holding company and our operating results are almost entirely derived from the operations of our insurance subsidiaries. Our core operating subsidiaries are The Medical Assurance Company, Inc., ProNational Insurance Company, NCRIC, Inc. and Red Mountain Casualty Insurance Company, Inc.; all principally write professional liability insurance. We also write a limited amount of medical professional liability insurance through Woodbrook Casualty Insurance, Inc. (formerly Medical Assurance of West Virginia, Inc.).
Corporate Strategy
Our goal is to build upon our position as a leading writer of professional liability insurance and expand principally within the mid-Atlantic, Midwest and Southeast, while maintaining our commitment to disciplined underwriting and aggressive claims management. According to A.M. Best, based on 2004 data, we are the fourth largest active medical liability insurance writer in the nation, and we believe we are the largest medical liability writer in our collective states of operation. We believe that our strong reputation in our regional markets, combined with our financial strength, strong customer service and proven ability to manage claims, should enable us to profitably expand our position in select states. We have successfully acquired and integrated companies and books of business in the past and believe our financial size and strength make us an attractive acquirer. We continually evaluate these opportunities to leverage our core underwriting and claims expertise.
We emphasize disciplined underwriting and do not manage our business to achieve a certain level of premium growth or market share. We apply our local knowledge to individual risk selection and determine the appropriate price based on our assessment of the specific characteristics of each risk. In addition to prudent risk selection, we seek to control our underwriting results through effective claims management. We investigate each claim and have fostered a strong culture of aggressively defending claims that we believe have no merit. We manage claims at the local level, tailoring claims handling to the legal climate of each state, which we believe differentiates us from national writers.
Through our regional underwriting and claims office structure, we are able to gain a strong understanding of local market conditions and efficiently adapt our underwriting and claims strategies to regional conditions. Our regional presence also allows us to maintain active relationships with our customers and be more responsive to their needs. We believe these factors allow us to compete on a basis other than just price. We also believe that our presence in local markets allows us to monitor and understand changes in the liability climate and thus develop better business strategies in a more timely manner than our competitors.
We have sustained our financial stability during difficult market conditions through responsible pricing and loss reserving practices. We are committed to maintaining prudent operating and financial leverage and conservatively investing our assets. We recognize the importance that our customers and producers place on the strong ratings of our principal insurance subsidiaries and we intend to manage our business to protect our financial security.
We measure performance in a number of ways, but particularly focus on our combined ratio and investment returns, both of which directly affect our return on equity (ROE). We target a long-term average ROE of 12% to 14%.
We believe that a focus on rate adequacy, selective underwriting and effective claims management is required if we are to achieve our ROE targets. We closely monitor premium revenues, losses and loss adjustment costs, and acquisition, underwriting and insurance expenses. Our investment portfolio is managed in order to meet the liquidity and profitability needs of each insurance company as well as to maximize after-tax investment returns on a consolidated basis. We engage in activities that generate other income; however, such activities, principally fee generating and agency services, do not constitute a significant source of revenues or profits.

Growth Opportunities and Outlook
We expect our future growth will be supported by controlled expansion in states where we are already writing business and into additional states within, or adjacent to, our existing business footprint. We also look to expand through the acquisition of other companies or books of business; however, such expansion is opportunistic and cannot be predicted.
We believe we are viewed as a market leader because of our financial strength and stability, and our ability to deliver excellent service at the local level. There have been several highly publicized insolvencies in our industry in recent years, and regulators have taken action against former competitors because of financial concerns. Thus, we believe our balance sheet strength and financial stability will continue to be a differentiating factor in the market.
We have seen an increase in competition during the year by both existing professional liability insurers as well as new entrants, primarily in the form of risk retention groups and other risk pooling mechanisms. While most existing competitors appear to be maintaining pricing and underwriting discipline, we are seeing an increase in competition, especially on price. The new entrants are typically more aggressive in seeking new business and are generally more willing to compete on price. As a result of these market forces, profitable growth in the coming year will be challenging. Nevertheless we will continue to price our products at levels that we believe meet our return objectives and we will continue to disregard business that does not.
We achieved average gross price increases of approximately 11%, 19% and 28%, on renewal business (weighted by premium volume) in 2005, 2004 and 2003, respectively. In 2006 we expect professional liability pricing to increase at a slower pace. The price increases implemented over the last several years have brought our pricing to a level that we believe is adequate to meet our return objectives. We plan to maintain this pricing level by using future rate increases to counteract loss cost inflation.
Recent Significant Events
On August 3, 2005 ProAssurance acquired all of the outstanding common stock of NCRIC Corporation (NCRIC) in a stock for stock merger. NCRIC’s primary business is a single property and casualty insurance company that provides medical professional liability insurance in the District of Columbia, Delaware, Maryland, Virginia and West Virginia. The primary purpose for the transaction was to expand marketing opportunities for our professional liability insurance products.
As part of the NCRIC merger, we also acquired ConsiCare, a subsidiary which provides administrative and financial services to physician practices. ConsiCare’s business focus is not consistent with our strategy as a specialty insurance company, and we therefore sold ConsiCare for $1.7 million on December 28, 2005. The operating results of ConsiCare are presented in the accompanying Consolidated Financial Statements as a component of discontinued operations. There was no gain or loss on the sale because our carrying value for ConsiCare approximated the sale price less sale expenses, adjusted for the tax effects of the sale.
The following chart summarizes the NCRIC acquisition:

|  | In millions |
Fair value of 1.7 million ProAssurance common shares issued |  | $ | 67.1 |
Other acquisition costs |  |  | 4.1 |
Aggregate purchase price |  |  | 71.2 |
Fair value of net assets acquired |  |  | 46.2 |
Excess of purchase price over fair value of net assets acquired, recognized as goodwill |  | $ | 25.0 |

On January 4, 2006 we sold our personal lines operations (the MEEMIC companies), effective January 1, 2006. The transaction is worth $400 million to us before transaction expenses. Motors Insurance Corporation (Motors), a subsidiary of GMAC Insurance Holdings, Inc., paid approximately $325 million in cash for MEEMIC Insurance Company and its internal agency, and we retained approximately $75 million of the MEEMIC companies’ pre-sale capital. Sale proceeds will support the capital

##### Table of Contents

requirements of our professional liability insurance subsidiaries and other general corporate purposes. Following the sale, our total assets will decline by $167.8 million ($567.8 million assets sold less proceeds of $400 million) and our liabilities will decline by $337.5 million. Our stockholders’ equity will increase by the gain recognized on the transaction, which we expect to be approximately $110 million after consideration of sale expenses and the tax effects of the sale.
Because these operations have been sold, the assets, liabilities and operating results of the MEEMIC companies are reported as a component of discontinued operations in our accompanying Consolidated Financial Statements for all periods presented. Previously, we reported our personal lines operations and our professional liability operations as separate reportable segments; net investment income of the parent holding company and interest expense on long-term debt (corporate income) were not allocated to either segment. This reporting structure was reflected in prior filings. Our continuing operations now represent a single reportable segment and combine corporate income with the results of the professional liability segment.
Additional information regarding the previously described transactions is provided in Note 2 “Acquisition of NCRIC” and Note 3, “Discontinued Operations” of the Notes to the Consolidated Financial Statements included herein.
On December 8, 2005, we reached a definitive agreement with Physicians Insurance Company of Wisconsin, Inc. (PIC Wisconsin) whereby we agreed to acquire PIC Wisconsin in an all-stock merger transaction having an estimated value of $100 million.
PIC Wisconsin is a Wisconsin-domiciled stock insurance company; its shares are not registered under the Securities Exchange Act of 1934. There is no GAAP financial data available for PIC Wisconsin. Audited December 31, 2004 statutory reports for PIC Wisconsin present cash and invested assets of $247.3 million, loss and loss adjustment expense reserves of $140.8 million, capital and surplus of $89.3 million and 2004 earned premiums of $56.5 million. The transaction is subject to approval by PIC Wisconsin shareholders and required regulatory approvals. We filed a registration statement and a proxy statement/prospectus with the Securities and Exchange Commission (SEC) on February 15, 2006 which is not yet effective. For more information regarding the proposed merger refer to the registration statement, SEC file number 333-131874.
Liquidity and Capital Resources and Financial Condition
The following discussions of changes in our financial condition and operating results exclude amounts that are classified as discontinued operations in our consolidated financial statements, as discussed under the caption “Recent Significant Events” and in Note 3 of our Consolidated Financial Statements.
ProAssurance Corporation is a legal entity separate and distinct from its subsidiaries. Because the parent holding company has no other business operations, dividends from its operating subsidiaries represent a significant source of funds for its obligations, including debt service. The ability of those insurance subsidiaries to pay dividends is subject to limitation by state insurance regulations. See our discussions under “Regulation of Dividends from Our Operating Subsidiaries” in Part I, and in Note 15 of our Notes to the Consolidated Financial Statements for additional information regarding dividend limitations.
Within our operating subsidiaries our primary need for liquidity is to pay losses and operating expenses in the ordinary course of business. Our operating activities provided positive cash flow of $323.6 million for the year ended December 31, 2005, which is comparable to cash provided by operations of $336.3 million for the year ended December 31, 2004. Our December 31, 2005 operating cash flow includes $16.3 million generated by NCRIC operating activities from the August 3 purchase date forward. The primary sources of our operating cash flows are net investment income and the excess of premiums collected over net losses paid and operating costs. Timing delays exist between the collection of premiums and the payment of losses. A general measure of this timing delay is the ratio of paid to incurred losses, which is computed by dividing paid losses for the period by incurred losses. Our paid to incurred loss ratios for the years ended December 31, 2005 and 2004 are 51.6% and 46.5%, respectively.

38

##### Table of Contents

The cash flows of the personal lines segment have historically not been used to support our professional liability operations. It is not expected that the sale of the personal lines segment will have a detrimental effect on the liquidity of our continuing operations.
We believe that rate adequacy is critical to our long-term liquidity. We continually review rates and submit requests for rate increases to state insurance departments as we consider necessary to maintain rate adequacy. We are unable to predict whether we will continue to receive approval for our rate filings. In most jurisdictions we are required to receive approval of these rate increases before we can factor them into the pricing of our products.
We manage our investment portfolio to ensure that it will have sufficient liquidity to meet our obligations, taking into consideration the timing of cash flows from our investments as well as the expected cash flows to be generated by our operations. At our insurance subsidiaries the primary outflow of cash is related to the payment of claims and expenses. The payment of individual claims cannot be predicted with certainty; therefore, we rely upon the history of paid claims in determining the expected future claims payments. To the extent that we have an unanticipated shortfall in cash we may either liquidate securities held in our investment portfolio or borrow funds under previously established borrowing arrangements. However, given the significant cash flows being generated by our operations and the relatively short duration of our investment portfolio we do not foresee any such shortfall.
Cash and invested assets increased $482.6 million over the prior year. The increase is attributable to the aforementioned operating cash flow as well as the addition of NCRIC, which held cash and investments of $237.1 million at December 31, 2005. The fair value of our investment portfolio decreased $43.2 million as a result of the rising rate environment in 2005. We transfer most of the cash generated from operations into our investment portfolio. We held cash and cash equivalents of approximately $34.5 million at December 31, 2005 and $20.7 million at December 31, 2004.
At December 31, 2005 our investment in fixed maturity securities is $2.4 billion, representing 91.4% of our total investments. Substantially all of our fixed maturities are either United States government agency obligations or investment grade securities as determined by national rating agencies. The fixed maturity securities in our investment portfolio have a dollar weighted average rating of “AA” at December 31, 2005. Our investment policy implements an asset allocation that uses length to maturity as one method of managing our long-term rate of return. The weighted average effective duration of our fixed maturity securities at December 31, 2005 is 3.91 years. Changes in market interest rate levels generally affect our net income to the extent that reinvestment yields are different than the original yields on maturing securities. Additionally, changes in market interest rates also affect the fair value of our fixed maturity securities. Bond interest rates have increased since December 31, 2004 and as a result average bond market values have decreased. On a pre-tax basis, net unrealized gains/losses related to our available-for-sale fixed maturity securities decreased from a net unrealized gain of $27.3 million at December 31, 2004 to a net unrealized loss of $15.2 million at December 31, 2005.
At December 31, 2005, available-for-sale and trading portfolio equity investments total $15.2 million, representing approximately 0.6% of our total investments, and approximately 2.0% of our capital. These holdings decreased from $33.6 million at December 31, 2004.
Our investment in short-term securities at December 31, 2005 is $93.1 million as compared to $37.9 million at December 31, 2004. Approximately $17.0 million of this increase is attributable to NCRIC. We have elected to hold more funds in short-term securities during 2005 in order to increase our investment flexibility in a rising rate environment. As our investment managers identify investment opportunities that are consistent with our longer range investment strategy we plan to move funds from short-term securities to longer term fixed maturity securities.
For a more detailed discussion of the effect of changes in interest rates on our investment portfolio see Item 7A, “Quantitative and Qualitative Disclosures about Market Risk.”

Our long-term debt at December 31, 2005 is comprised of the following:

|  | Due |  | Rate |  | 2005 |
|  |  |  |  |  | In thousands |
Convertible Debentures |  | June 2023 |  | 3.90%, fixed |  | $ | 105,381 |

|  |  |  |  |  | $ | 167,240 |

* |  | Assumed in NCRIC transaction

We may redeem the Convertible Debentures on or after July 7, 2008 with notice. Holders may require us to repurchase their debentures on June 30 of 2008, 2013, and 2018. Also, holders may convert their debentures if the market value of our common stock exceeds the product of the conversion price (currently $41.83) multiplied by 120% for 20 of the 30 trading days ending on the last trading day of the immediately preceding quarter. Upon conversion, holders will receive 23.9037 shares of common stock for each $1,000 principal amount of debentures surrendered for conversion. We have the right to deliver, in lieu of common stock, cash or a combination of cash and shares of common stock.
The 2032 and 2034 Subordinated Debentures may be redeemed at our option in December 2007 and April 2009, respectively.
See Note 10 of our Consolidated Financial Statements for additional information regarding our long-term debt.
As a result of the acquisition of NCRIC, we assumed the risk of loss for a judgment entered against NCRIC on February 20, 2004 by a District of Columbia Superior Court in favor of Columbia Hospital for Women Medical Center, Inc. (“CHW”) in the amount of $18.2 million (the “CHW judgment”). By order of September 30, 2005, the trial court denied all post-trial relief sought by NCRIC and NCRIC has appealed the judgment. NCRIC posted a $19.5 million appellate bond and associated letter of credit to secure payment of the CHW judgment plus interest and costs, in the event the judgment is ultimately affirmed and paid. In accordance with SFAS 141, we established a liability of $19.5 million for this judgment and included the liability as a component of the fair value of assets acquired and liabilities assumed in the allocation of the NCRIC purchase price.
Losses
Losses are the largest component of expense for our operations. As discussed in critical accounting policies, net losses in any period reflect our estimate of net losses related to the premiums earned in that period as well as any changes to our estimates of the reserve established for net losses of prior periods.
The estimation of medical professional liability losses is inherently difficult. Injuries may not be discovered until years after an incident, or the claimant may delay pursuing the recovery of damages. Ultimate loss costs, even for similar events, vary significantly depending upon many factors, including but not limited to the nature of the injury and the personal situation of the claimant or the claimants’ family, the judicial climate where the insured event occurred, general economic conditions and the trend of health care costs. Medical liability claims are typically resolved over an extended period of time, often five years or more. The combination of changing conditions and the extended time required for claim resolution results in a loss cost estimation process that requires actuarial skill and the application of judgment, and such estimates require periodic revision.
In establishing our reserve for loss and loss adjustment expenses management considers a variety of factors including historical paid and incurred loss development trends, the effect of inflation on medical care, general economic trends and the legal environment. Given the number of factors considered it is neither practical nor meaningful to isolate a particular assumption or parameter of the process and calculate the impact of changing that single item. We perform an in-depth review of our loss reserve on a semi-annual basis. However, management is continually reviewing and updating the data

40

##### Table of Contents

underlying the estimation of our loss reserve and we make adjustments that we believe the emerging data indicate. Any adjustments necessary are reflected in the then-current operations.
As a result of the variety of factors that must be considered by management there is a significant risk that actual incurred losses will develop differently from these estimates. We use a variety of actuarial methodologies in performing these analyses. Among the methods that we have used are:

| – Paid development method
| – Reported development method
| – Bornhuetter-Ferguson method
| – Average paid value method
| – Average reported value method
| – Backward recursive method

Generally, methods such as the Bornheutter-Ferguson method are used on more recent accident years where we have less data on which to base our analysis. As business seasons and we have an increased amount of data for a given accident year we begin to give more confidence to the development and average methods as these methods typically rely more heavily on our own historical data. Each of these methods treats our assumptions differently, and thus provides a different perspective on the particular business under review.
The various actuarial methods discussed above are applied in a consistent manner from period to period. In addition, we perform statistical reviews of claim data such as claim counts, average settlement costs and severity trends.
In performing these analyses we partition our business by type, coverage type, geography, layer of coverage and accident year. This procedure is intended to balance the use of the most representative data for each partition, capturing its unique patterns of development and trends. For each partition, the results of the various methods, along with the supplementary statistical data regarding such factors as the current economic environment, are used to develop a point estimate based upon management’s judgment and past experience. The process of selecting the point estimate from the set of possible outcomes produced by the various actuarial methods is based upon the judgment of management and is not driven by formulaic determination. For each partition of our business we select a point estimate with due regard for the age, characteristics and volatility of the partition of the business, the volume of data available for review and past experience with respect to the accuracy of estimates for business of a similar type. This series of selected point estimates is then combined to produce an overall point estimate for ultimate losses.
The Company has modeled implied reserve ranges around its single point reserve estimates for its professional liability business assuming different confidence levels. The ranges have been developed by aggregating the expected volatility of losses across partitions of our business to obtain a consolidated distribution of potential reserve outcomes. The aggregation of this data takes into consideration the correlation among the Company’s geographic and specialty mix of business. The result of the correlation approach to aggregation is that the ranges are narrower than the sum of the ranges determined for each partition.
The Company has used this modeled statistical distribution to calculate an 80% and 60% confidence interval for the potential outcome of our reserves. The high and low end points of the ranges are as follows:

|  | Low End Point |  |  | Carried Reserves |  |  | High End Point |
80% Confidence Level |  | $1.383 billion |  | $1.897 billion |  | $2.355 billion
60% Confidence Level |  | $1.505 billion |  | $1.897 billion |  | $2.128 billion

The development of a reserve range models the uncertainty of the claim environment as well as the limited predictive power of past loss data. These uncertainties and limitations are not specific to the Company. The ranges represent an estimate of the range of possible outcomes and should not be confused with a range of best estimates. Any change in our estimate of reserves would be reflected in then-current operations. Due to the size of our reserve for losses, even a small percentage adjustment to

these estimates could have a material effect on our results of operations for the period in which the adjustment is made.
The following table, known as the Loss Reserve Development Table, presents information over the preceding ten years regarding the payment of our losses as well as changes to (the development of) our estimates of losses during that time period. Years prior to 2001 relate only to the reserves of Medical Assurance. In years 2001 and thereafter the table reflects the reserves of ProAssurance, formed in 2001 in order to merge Medical Assurance and Professionals Group. NCRIC reserves are included only in the year 2005 since NCRIC was acquired in that year. The table does not include the loss reserves of personal lines operations, which are reflected in our financial statements as discontinued operations.
The table includes losses on both a direct and an assumed basis and is net of reinsurance recoverables. The gross liability for losses before reinsurance, as shown on the balance sheet, and the reconciliation of that gross liability to amounts net of reinsurance are reflected below the table. We do not discount our reserves to present value. Information presented in the table is cumulative and, accordingly, each amount includes the effects of all changes in amounts for prior years. The table presents the development of our balance sheet reserves; it does not present accident year or policy year development data. Conditions and trends that have affected the development of liabilities in the past may not necessarily occur in the future. Accordingly, it may not be appropriate to extrapolate future redundancies or deficiencies based on this table.
The following may be helpful in understanding the Loss Reserve Development Table:

| – |  | The line entitled “Reserve for losses, undiscounted and net of reinsurance recoverables” reflects the Company’s reserve for losses and loss adjustment expense, less the receivables from reinsurers, each as showing in the Company’s consolidated financial statements at the end of each year (the Balance Sheet Reserves).
| – |  | The section entitled “Cumulative net paid, as of” reflects the cumulative amounts paid as of the end of each succeeding year with respect to the previously recorded Balance Sheet Reserves.
| – |  | The section entitled “Re-estimated net liability as of” reflects the re-estimated amount of the liability previously recorded as Balance Sheet Reserves that includes the cumulative amounts paid and an estimate of additional liability based upon claims experience as of the end of each succeeding year (the Net Re-estimated Liability).
| – |  | The line entitled “Net cumulative redundancy (deficiency)” reflects the difference between the previously recorded Balance Sheet Reserve for each applicable year and the Net Re-estimated Liability relating thereto as of the end of the most recent fiscal year.

In each year reflected in the table, we have utilized the actuarial methodologies discussed previously to estimate reserves. These techniques are applied to the data in a consistent manner and the resulting projections are evaluated by management to establish the estimate of reserves.
Factors that have contributed to the variation in loss development include the following:

| – |  | Our volume of business and the corresponding data in the late 1980’s and early 1990’s, while substantial, was not of a sufficient size to fully support the actuarial projection process without the use of industry-based data. Substantially all of our business was derived from medical professional liability insurance written in Alabama until we began to geographically expand our business in the mid to late 1990s. We utilized a rigorous and disciplined approach to investigating, managing and defending claims. This philosophy generally produced results in Alabama that were better than industry averages in terms of loss payments and the proportion of claims closed without indemnity payment. Ultimately, actual results proved better than the industry data, creating redundancies.
| – |  | Our reserves established in the late 1980’s and early 1990’s were strongly influenced by the dramatically increased frequency and severity that we, and the industry as a whole, experienced during the mid-1980s. Some of these trends moderated, and in some cases, reversed, by the late 1980s or early 1990s. However, the ability to recognize the improved environment was delayed due to the extended time required for claims resolution. When these negative trends moderated, the reserves we established during those periods proved to be redundant.
| – |  | The professional liability legal environment deteriorated once again in the late 1990’s. Beginning in 2000, we recognized adverse trends in claim severity causing increased estimates of certain loss liabilities. As a result, favorable development of prior year loss reserves slowed in 2000 and reversed in 2001 and 2002. We have addressed these trends through increased rates, stricter underwriting and modifications to claims handling procedures.
| – |  | During 2004 and 2005 we recognized favorable development related to our previously established reserves, primarily to reflect reductions in our estimates of claim severity.

At December 31, 2005 our reserve for losses, net of the receivable from reinsurers, is $1.9 billion, an increase of $351.8 million over net reserves at December 31, 2004, which includes NCRIC net reserves acquired in August of $139.7 million. Our receivable from reinsurers at December 31, 2005 is $327.7 million, of which $41.3 million is attributable to NCRIC. Our reserve for losses continues to grow given the generally long-tailed nature of professional liability lines of business. Several years can pass between the initial recognition of a claim and the ultimate settlement of that claim. This, coupled with the growth in the number of policies we issue has resulted in an increase in loss reserve. Activity in the net reserve for losses during 2005, 2004 and 2003 is summarized below:

At December 31, 2005 our gross loss reserves included case reserves of approximately $1.240 billion and IBNR reserves of approximately $984 million. Our insurance subsidiaries had consolidated reserves for losses on a GAAP basis that exceeded those on a statutory basis by approximately $29.6 million, which is principally due to the portion of GAAP reserves that are reflected for statutory accounting purposes as unearned premiums. These unearned premiums are applicable to extended reporting endorsements (“tail” coverage) issued without a premium charge upon death, disability, or retirement of an insured.
Reinsurance
We use reinsurance to provide capacity to write large limits of liability, to reduce losses of a catastrophic nature and to stabilize underwriting results in those years in which such losses occur. The purchase of reinsurance does not relieve us from the ultimate risk on our policies, but it does provide reimbursement from the reinsurer for certain losses paid by us.
We reinsure professional liability risks under treaties pursuant to which the reinsurer agrees to assume all or a portion of all risks that we insure above our individual risk retention of $1 million per claim, up to the maximum individual limit offered (currently $16 million). Historically, per claim retention levels have varied between the first $200,000 and the first $2 million depending on the coverage year and the state in which business was written. Periodically, we provide insurance to policyholders above the maximum limits of our primary reinsurance treaties. In those situations, we reinsure the excess risk above the limits of our reinsurance treaties on a facultative basis, whereby the reinsurer agrees to insure a particular risk up to a designated limit.
Our risk retention level is dependent upon numerous factors including our risk appetite and the capital we have to support it, the price and availability of reinsurance, volume of business, level of

experience and our analysis of the potential underwriting results within each state. Our 2005-2006 reinsurance treaties renewed with minimal change in terms or conditions from the prior year.
The effective transfer of risk is dependent on the credit-worthiness of the reinsurer. We purchase reinsurance from a number of companies to mitigate concentrations of credit risk. Our reinsurance broker assists us in the analysis of the credit quality of our reinsurers. We base our reinsurance buying decisions on an evaluation of the then-current financial strength, rating and stability of prospective reinsurers. However, the financial strength of our reinsurers, and their corresponding ability to pay us, may change in the future due to forces or events we cannot control or anticipate.
We have not experienced any significant difficulties in collecting amounts due from reinsurers due to the financial condition of the reinsurer. Should future events lead us to believe that any reinsurer is unable to meet its obligations to us, adjustments to the amounts recoverable would be reflected in the results of current operations.
At December 31, 2005 our receivable from reinsurers approximated $328 million. The following table identifies our reinsurers from which our recoverables (net of amounts due to the reinsurer) are $10 million or more as of December 31, 2005:

Off Balance Sheet Arrangements/Guarantees
As discussed in Note 10 to our Consolidated Financial Statements, our 2032 and 2034 Debentures are held by, and are the sole assets of, related business trusts. The NCRIC Trust purchased the 2032 Debentures and the PRA Trusts purchased the 2034 Debentures with proceeds from related trust preferred stock (TPS) issued and sold by each trust. The terms and maturities of the 2032 and 2034 Subordinated Debentures mirror those of the related TPS. The NCRIC and PRA Trusts will use the debenture interest and principal payments we pay into each trust to meet their TPS obligations. In accordance with the guidance given in Financial Accounting Standards Board Interpretation No. 46R, “Variable Interest Entities,” (FIN 46R) the NCRIC and PRA Trusts are not included in our consolidated financial statements because we are not the primary beneficiary of either trust.
NCRIC and ProAssurance have issued guarantees that amounts paid to the NCRIC and PRA Trusts related to the 2032 and 2034 Subordinated Debentures will subsequently be remitted to the holders of the related TPS. The amounts guaranteed are not expected to at any time exceed our obligations under the 2032 and 2034 Subordinated Debentures, and we have not recorded any additional liability related to the guarantee.

All long-term debt is assumed to be settled at its contractual maturity. Interest on long-term debt is calculated using interest rates in effect at December 31, 2005 for variable rate debt. For more information see Note 10 to our Consolidated Financial Statements. The anticipated payout of loss and loss adjustment expenses is based upon our historical payout patterns. Both the timing and amount of these payments may vary from the payments indicated. Our operating lease obligations are primarily for the rental of office space, office equipment, and communications lines and equipment.

Effect of Acquisition of NCRIC
We acquired NCRIC on August 3, 2005 and our results for the year ended December 31, 2005 include NCRIC results since the date of acquisition only. In the following tables, in order to facilitate an understanding of the effect of NCRIC, we have segregated results attributable to NCRIC in a separate line item titled “NCRIC”. The designation “PRA, prior” refers to ProAssurance’s results excluding NCRIC. Unless otherwise indicated, our discussions of variances between operating periods are presented exclusive of the amounts attributed to NCRIC operations.
Premiums
Premiums written changed in 2005 as a result of competition, selective underwriting, the reduced need for rate increases and the acquisition of NCRIC. This acquisition is consistent with our stated strategy to grow premiums both organically and through selective acquisitions.

|  | Gross Premiums Written
|  | Year Ended December 31

Continuing operations |  | $ | 572,960 |  |  | $ | 573,592 |  |  | $ | (632 | ) |  |  | (0.1 | %)

Premiums written vary from period to period for a number of reasons. Some of the more common differences result from changes to premium rates, changes in the coverages chosen by our insureds, the volume of new business written during the period, the loss of business to competitors or due to our own underwriting decisions, and the percentage of our policies that renew, which may also affect the level of tail premiums written. Changes in the markets in which we operate, such as the entry or exit of a competitor in a given market and changes in the rate structures of our competitors, also affect written premiums from period to period. The effect of any of these changes also varies by the proportion of policies written or renewed during each period in the various geographical regions and classes of business in which we operate.
Approximately $16.0 million of the 2005 decrease in premiums written, excluding NCRIC, represents a decrease in physician premiums for non-tail coverages, which is our principal insurance product, comprising 84% of our total 2005 written premiums. In 2005, rates on our renewed policies averaged 11% higher than the expiring premiums. However, the beneficial effect of the rate increases and new business was offset by the effect of policies that did not renew. In addition, some insureds chose to take lower limits of coverage, and in some cases we decided to move away from volatile jurisdictions where rates are higher toward stable states where rates may be lower. Our retention rate averaged 85% in 2005, as compared to 83% in 2004, but increased price competition in several states reduced the volume of new business that we were able to write. We remain committed to an adequate rate structure and have forgone business that we believed could not be written at profitable rates.
Tail policies are offered to insureds that are discontinuing their claims-made coverage with us, and the amount of tail premium written in any annual period can and does vary widely. Tail premiums represented approximately 5% of total written premiums in 2005 and approximately 6% of total written premiums in 2004. Tail premiums declined by approximately $7.7 million in 2005 as compared to 2004. While we offer tail coverage to departing insureds as an obligation under our policy provisions, our preference is to sell less rather than more of this coverage since it represents a long-term liability with increased pricing risk.
Hospital premiums, which comprise 7% of our premiums written in 2005 and 2004, declined by approximately $1.9 million as compared to 2004. Such business is highly price sensitive. As in all our lines, we choose not to compete primarily on price because our focus is on maintaining adequate margins on the policies we sell. Thus, our hospital premiums fluctuate based on competitive forces largely beyond our control.

Because premiums are generally earned pro rata over the entire policy period after the policy is written, fluctuations in premiums earned tend to lag those of premiums written. Policies generally carry a term of one year. Professional liability tail policies are 100% earned in the period written because the policies are non-cancelable and insure only incidents that occurred in prior periods.
The increase in 2005 earned premiums reflects on a pro rata basis the changes in written premiums that occurred during both 2005 and late 2004, reduced by lower tail premiums written in 2005 as discussed in the section on premiums written.

Premiums ceded represent the portion of earned premiums that we must ultimately pay to our reinsurers for their assumption of a portion of our losses.
We reduced ceded premiums by $8.9 million in 2004 to reflect changes in our estimates of the amount of reinsurance premiums due for certain prior accident years, based on the provisions of the reinsurance contracts and our estimates of the reinsured losses for those prior accident years. We also reduced ceded premiums in 2004 by approximately $1.6 million due to the commutation of certain reinsurance contracts. After consideration of the effect of these adjustments, there is little change in 2005 ceded premiums as compared to 2004.
Losses and Loss Adjustment Expenses
The estimation of medical professional liability losses is inherently difficult. Injuries may not be discovered until years after an incident, or the claimant may delay pursuing the recovery of damages. Ultimate loss costs, even for similar events, vary significantly depending upon many factors, including but not limited to the nature of the injury and the personal situation of the claimant or the claimant’s family, the judicial climate where the insured event occurred, general economic conditions and the trend of health care costs. Medical liability claims are typically resolved over an extended period of time, often five years or more. The combination of changing conditions and the extended time required for claim resolution results in a loss cost estimation process that requires actuarial skill and the application of judgment, and such estimates require periodic revision.
Calendar year losses may be divided into three components: (i) actuarial evaluation of incurred losses for the current accident year; (ii) actuarial re-evaluation of incurred losses for prior accident years; and (iii) actuarial re-evaluation of the reserve for the death, disability and retirement provision (DDR) in our claims-made policies.
Accident year refers to the accounting period in which the insured event becomes a liability of the insurer. For occurrence policies the insured event becomes a liability when the event takes place; for claims-made policies the insured event becomes a liability when the event is first reported to the insurer. We believe that measuring losses on an accident year basis is the most indicative measure of the underlying profitability of the premiums earned in that period since it associates policy premiums earned with our estimate of the losses incurred related to those policy premiums. Calendar year results include

* Net losses as specified divided by net premiums earned.

Current accident year net loss ratios are lower in 2005 as compared to 2004 due to several factors. We have focused for several years on developing and maintaining adequate rates. As rate adequacy has improved, loss ratios have decreased. Also, our expected loss ratios vary based upon geographic location, coverage type and coverage limits. In 2005 as compared to 2004, changes in the mix of insured risks reduced overall expected loss ratios. During 2005 we recognized favorable development of $23.0 million related to our previously established reserves, primarily to reflect reductions in our estimates of claim severity. The most significant reduction was seen in the 2003 accident year; however, favorable development was also seen in accident years 2002 and prior.
Assumptions used in establishing our reserve are regularly reviewed and updated by management as new data becomes available. Any adjustments necessary are reflected in current operations. Due to the size of our reserve, even a small percentage adjustment to the assumptions can have a material effect on our results of operations for the period in which the change is made.

Gross Losses and Reinsurance Recoveries
The effect of adjustments made to reinsured losses is mitigated by the corresponding adjustment that is made to insurance recoveries. Thus, in any given year, we may make significant adjustments to gross losses that have a less significant effect on our net losses. The following table reflects our losses on both a gross and a net basis.

When discussing losses that are reinsured and losses that are retained, it is common to refer to “layers” of loss. The retained layer is the cumulative portion of each loss, on a per-claim basis, which is less than our reinsurance retention for a given coverage year. Likewise, the reinsured layer is the cumulative portion of each loss that exceeds the reinsurance retention.
Our 2005 actuarial analysis of our reserve indicated that our claims severity had continued to increase as expected in our retained layers, but not to the degree anticipated in our original reserve estimates. This was also true in our reinsured layers, but the variance between our original estimates and the 2005 actuarial estimate was smaller. Accordingly, we reduced our estimates of prior accident year gross losses by $24.6 million and reduced the prior accident year reinsurance recoveries by $1.6 million, for a net adjustment to prior year losses of $23.0 million.
Our 2004 actuarial analysis of our reserve indicated that our claims severity had continued to increase as expected in risk retained by ProAssurance. However, in risks ceded to our reinsurers actual loss experience proved to be lower than we originally anticipated and for which we established our reserve. Accordingly, we reduced our estimates of prior accident year gross losses by approximately $60.4 million and reduced the corresponding reinsurance recoveries by $51.7 million, for a net adjustment to prior year losses of $8.7 million. The decrease to reinsurance recoveries for prior accident years more than offset reinsurance recoveries for current accident years resulting in a non-traditional relationship between gross losses and recoveries for the year ended December 31, 2004.

Net Investment Income and Net Realized Investment Gains (Losses)
Net investment income is primarily derived from the interest income earned by our fixed maturity securities and includes interest income from short-term and cash equivalent investments, dividend income from equity securities, earnings from limited partnerships, increases in the cash surrender value of business owned executive life insurance contracts, and rental income earned by our commercial real estate holdings. Investment fees and expenses and real estate expenses are deducted from investment income.

Continuing operations |  | $ | 97,649 |  |  | $ | 76,346 |  |  | $ | 21,303 |  |  |  | 27.9 | %

The increase in net investment income is principally due to higher average invested funds during 2005. The positive cash flow generated by our insurance operations significantly increased our average invested funds. Rising market interest rates also contributed to the improvement in net investment income. Rates began to increase in mid-2004, allowing new and maturing funds to be invested at higher rates. Our average income yield, on a consolidated basis, excluding NCRIC, was 4.2% for 2005 as compared to 4.0% for 2004. Our average tax equivalent income yield on a consolidated basis, excluding NCRIC, was 4.8% for the year ended December 31, 2005 as compared to 4.4% for the year ended December 31, 2004. We increased the proportion of the portfolio that is invested in tax-exempt securities because of the higher after-tax yields available on these securities; therefore, our average after-tax equivalent income yield improved more than our average income yield.
The components of net realized investment gains (losses) are shown in the following table.

Underwriting, Acquisition and Insurance Expenses
Underwriting, acquisition and insurance expenses are comprised of variable costs, such as commissions and premium taxes that are directly related to premiums earned, and fixed costs that have an indirect relationship to premium volume, such as salaries, benefits, and facility expenses.
Our 2005 underwriting, acquisition and insurance expenses reflect higher compensation and benefit costs offset by a decrease in variable costs due to lower premium volume. The slight upward shift of the expense ratio as compared to 2004 is principally due to the increase in compensation costs.

Guaranty fund assessments were approximately $226,000 for the year ended December 31, 2005 as compared to approximately $396,000 for the year ended December 31, 2004.
Interest Expense
Interest expense increased in 2005 as compared to 2004 primarily because the average amount of debt outstanding was higher in 2005 and because interest rates increased in 2005. In the early part of 2004, our only outstanding debt was our Convertible Debentures. In April and May of 2004 we issued our 2034 Subordinated Debentures of $46.4 million; we added the 2032 Debentures of $15.5 million in August 2005 as a part of the NCRIC transaction. Our Convertible Debentures have a fixed interest rate; our Subordinated Debentures have variable rates.
Taxes
Our effective tax rate for each period is significantly lower than the 35% statutory rate because a considerable portion of our net investment income is tax-exempt. The effect of tax-exempt income on our effective tax rate is shown in the table below:

Recent Accounting Pronouncements and Guidance
On December 16, 2004 the Financial Accounting Standards Board (FASB) issued SFAS 123 (revised 2004), Share-Based Payment, hereafter referred to as SFAS 123(R), which is a revision of SFAS 123, Accounting for Stock-Based Compensation (SFAS 123), which superseded APB 25, Accounting for Stock Issued to Employees and amends SFAS 95, Statement of Cash Flows. The provisions of SFAS 123(R) require all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values. SFAS 123(R) also requires that the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow, rather than as an operating cash flow as required under current literature. We plan to adopt SFAS 123(R) on January 1, 2006, the required effective date, using the “modified prospective” method permitted by the statement and will value future grants of stock options using the Black Scholes valuation method.
Under the “modified prospective” method stock-based compensation is recognized under the requirements of SFAS 123(R) for all share-based payments granted after the effective date of SFAS 123(R) and for the non-vested portion of share-based payments granted prior to the adoption of SFAS 123(R). Under SFAS 123(R) compensation for non-vested share-based payments granted prior to adoption shall continue to be calculated as disclosed under SFAS 123, except that the effect of forfeitures is required to be estimated rather than considered as forfeitures occur.
As permitted by SFAS 123, we currently value employee stock-based payments using APB 25’s intrinsic value method. Accordingly, we generally recognize no compensation cost related to such payments but do provide pro forma disclosure of the effect on net income and earnings per share of applying the fair value provisions of SFAS 123 to such payments granted.
Had our SFAS 123 pro forma disclosures been prepared in accordance with the provisions of SFAS 123(R) the effect would have been different; however, the effect that SFAS 123(R) would have had on prior periods is not readily determinable. SFAS 123(R) provides more extensive guidance than does SFAS 123 with regard to factors that should be considered in valuing share-based payments. Under SFAS 123, we utilized a single set of valuation assumptions for all employees. Under SFAS 123(R), entities are required to “aggregate individual awards into relatively homogeneous groups with respect to exercise and post-vesting employment termination behaviors.” In order to appropriately reflect differing exercise and post-vesting employee termination behaviors, we anticipate aggregating prospective awards into groups consisting of senior executives, likely to exercise shortly after vesting, other senior executives and other employees. Additionally, under SFAS 123(R), fully vested awards granted to directors and awards that vest upon retirement granted to employees who are eligible for retirement will be expensed on the date of grant. Under SFAS 123, we calculated compensation expense (for pro forma disclosure) without consideration of expected forfeitures. Unlike SFAS 123, which permitted companies to reflect forfeitures as they occurred, SFAS 123(R) requires companies to estimate forfeitures in determining the amount of compensation cost to recognize each period. As a result, we will develop estimates of forfeitures during the requisite service periods and revise previous SFAS 123 calculations for known and expected forfeitures related to grants prior to the adoption of SFAS 123(R). Our own history with regard to the expected terms of employee stock awards is not sufficient to allow such assumptions to be developed statistically for most employee groups. Accordingly, for such groups, through December 31, 2007, we will apply the “simplified” method consistent with the guidance of SEC Staff Accounting Bulletin 107, i.e., expected term = (vesting term + original contractual term) / 2). We are in the process of finalizing these assumptions; however, the selection of all assumptions is not complete.
Presently, we estimate that the recognition of compensation cost, net of tax effects, for the non-vested portion of share-based payments granted prior to the adoption of SFAS 123(R) will approximate $1.3 million, net of related tax effects, during fiscal 2006. The further effect of adoption of SFAS 123(R) on future operating results will depend on the levels of share-based payments granted in the future, the groups of employees to whom the awards are granted, the number of awards granted to employees who are eligible for retirement, the terms of any future awards, as well as the final methods and assumptions used to determine the fair value of those share-based payments.
The FASB issued SFAS 154, Accounting Changes and Error Corrections, in May 2005 as a replacement of APB 20, Accounting Changes, and SFAS 3, Reporting Accounting Changes in Interim Financial Statements. SFAS 154 applies to voluntary changes in accounting principle and changes the

requirements for accounting for and reporting of a change in accounting principle and is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. ProAssurance expects to adopt SFAS 154 on its effective date.

Premiums
Written
Premiums exhibited strong growth in 2004; however, the growth was at a slower pace than in 2003 primarily because we implemented smaller rate increases in 2004 as compared to 2003. Our rates are based on our expected losses for the coverages provided; the cumulative effect of the rate increases we obtained in the past several years allowed us to pursue lower rate increases in some states in 2004. On average, renewals during the year ended December 31, 2004 were at rates that are approximately 19% higher than expiring rates. Rate increases on 2003 renewals, on average, were at rates that were 28% higher than expiring rates. New business written in 2004 was largely offset by business that did not renew, including business that we selectively chose not to renew.
Virtually all of the growth that we experienced in 2004 was related to physician coverages. This growth included an increase of approximately $5.0 million related to physician tail policies. Premiums written for this coverage can vary significantly from year to year.
Earned
Premiums are earned pro rata over the entire policy period (generally one year) after the policy is written. Thus the increase in 2004 earned premiums reflects on a pro rata basis the changes in written premiums that occurred during both 2004 and 2003.
Ceded
Premiums ceded represent the portion of earned premiums that we must ultimately pay to our reinsurers for their assumption of a portion of our losses.
In both 2004 and 2003, we reduced our estimates of prior year gross losses. As a result of the features of our reinsurance contracts, we also reduced our estimates of ultimate ceded premiums. The reduction was $8.9 million in 2004 and $5.4 million in 2003. Premiums ceded were also reduced by $1.6 million in 2004 due to the commutation of certain reinsurance contracts. Also, insureds have purchased policies with coverage limits below our reinsurance attachment point. We do not cede these premiums, and as a result, premiums ceded declined.
Losses and Loss Adjustment Expenses
The following table summarizes net losses and net loss ratios for the years ended December 31, 2004 and 2003 by separating losses between the current accident year and all prior accident years. The net loss ratios shown are calculated by dividing the applicable net losses by calendar year net premiums earned.

|  | Net Losses |  |  | Net Loss Ratios* |
|  | Year Ended December 31 |  |  | Year Ended December 31 |
|  |  |  |  |  |  |  |  |  | Increase |  |  |  |  |  |  |  |  |  |  | Increase |

Current accident year |  | $ | 469,151 |  |  | $ | 439,418 |  |  | $ | 29,733 |  |  |  | 90.2 | % |  |  | 95.6 | % |  |  | (5.4 | )

* |  | Net losses as specified divided by net premiums earned.

During 2004, we continued to see an increase in loss severity, which increased loss costs. Current accident year net loss ratios are lower in 2004 than in 2003 primarily because loss costs increased at a slower pace than premium rates. Loss ratios have also improved because we converted our occurrence policies to claims-made coverage. Generally, loss ratios associated with claims-made coverage are initially lower than those associated with occurrence coverage.

##### Table of Contents

We decreased our estimate of prior year net losses by $8.7 million in 2004 and $50,000 in 2003. The 2004 amount represents 0.7% of 2003 net reserves. These adjustments were in response to actuarial evaluations of loss reserves performed during the period. No change was made to our estimates of the reserves required for death, disability and retirement during 2004 or 2003.
Gross Losses and Reinsurance Recoveries
The following table reflects our losses on both a gross and a net basis.

|  | Gross and Net Losses |
|  | Year Ended December 31 |
|  |  |  |  |  |  |  |  |  | Increase |
|  | 2004 |  |  | 2003 |  |  | (Decrease) |
|  | In thousands |
Gross losses |  | $ | 447,521 |  |  | $ | 414,828 |  |  | $ | 32,693 |
Reinsurance recoveries |  | $ | (12,916 | ) |  | $ | (24,540 | ) |  | $ | 11,624 |
Net losses |  | $ | 460,437 |  |  | $ | 439,368 |  |  | $ | 21,069 |

In 2004, as was also the case in 2003, our actuarial analysis of our reserves indicated that our claims severity had continued to increase as expected in our retained layers. However, we did not experience the high level of losses in our reinsured layers that we originally anticipated and for which we established reserves. Accordingly, we reduced our estimates of prior accident year gross losses by approximately $60.4 million during the year ended December 31, 2004 and $74.2 million during the year ended December 31, 2003. These losses were heavily reinsured; therefore, we reduced expected reinsurance recoveries by $51.7 million in 2004 and $74.1 million in 2003. As previously discussed, these changes to prior year estimates reduced net losses by $8.7 million in 2004 and nominally reduced net losses in 2003. In both 2004 and 2003, the decrease to reinsurance recoveries for prior accident years more than offset reinsurance recoveries for current accident years resulting in a non-traditional relationship between gross losses and recoveries.
Assumptions used in establishing our reserves are regularly reviewed and updated by management as new data becomes available. Any adjustments necessary are reflected in current operations. Due to the size of our reserves, even a small percentage adjustment to the assumptions can have a material effect on our results of operations for the period in which the change is made.
Net Investment Income and Net Realized Investment Gains (Losses)
The increase in our net investment income in 2004 as compared to 2003 is due to higher average invested funds in 2004, offset by a slight decline in the yield of our fixed maturity securities. While prevailing market interest rates have remained historically low, changes in the duration and asset mix of the portfolio have helped to stabilize the yield of the portfolio. We increased the weighted average duration of the portfolio from 3.5 years at December 31, 2003 to 3.9 years at December 31, 2004 in order to take advantage of improved yields on certain longer term securities. We have also increased the proportion of the portfolio that is invested in tax-exempt securities because of the higher after-tax yields available on these securities. However, we continued to see some decline in our income yields as older, higher yielding securities matured or were sold. Our average income yield, on a consolidated basis, was 4.0% for the year ended December 31, 2004 as compared to 4.5% for the year ended December 31, 2003. Our average tax equivalent income yield on a consolidated basis was 4.4% for the year ended December 31, 2004 as compared to 4.9% for the year ended December 31, 2003.

Underwriting, Acquisition and Insurance Expenses
Underwriting, acquisition and insurance expenses are comprised of variable costs, such as commissions and premium taxes that are directly related to premiums earned, and fixed costs that have an indirect relationship to premium volume, such as salaries, benefits, and facility costs assessments. Underwriting, acquisition and insurance expenses increased in 2004 principally due to additional commission expense incurred as a result of premium growth. Changes in the mix of premiums by state and coverage type also increased commission expense. We also experienced increases in costs for salaries, benefits and professional fees, most significantly those fees related to Sarbanes-Oxley compliance.
The expense ratio (underwriting, acquisition and insurance expenses divided by net premiums earned) increased slightly in 2004 to 16.2% as compared to 15.9% in 2003. The increase is principally attributable to higher commission costs.
Guaranty fund assessments were approximately $396,000 for the year ended December 31, 2004 as compared to approximately $100,000 for the year ended December 31, 2003.
Interest Expense
Interest expense increased in 2004 as compared to 2003 primarily because the average amount of debt outstanding was higher in 2004 but also because interest was paid at a higher rate in the first half of 2004 as compared to the first half of 2003. In the first half of 2003 our only debt was an outstanding bank term loan. In July 2003 we issued $107.6 million of Convertible Debentures at a fixed rate of 3.9% and repaid a $67.5 million bank term loan which carried a variable rate. We increased our debt again in April and May of 2004, when we issued Subordinated Debentures of $46.5 million.
Taxes
Our effective tax rate for each period is significantly lower than the 35% statutory rate because a considerable portion of our net investment income is from tax-exempt interest and dividends. The effect of tax-exempt income on our effective tax rate is shown in the table below:

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.
We believe that we are principally exposed to three types of market risk related to our investment operations. These risks are interest rate risk, credit risk and equity price risk.
The term market risk refers to the risk of loss arising from adverse changes in market rates and prices, such as interest rates, equity prices and foreign currency exchange rates.
As of December 31, 2005, our fair value investment in fixed maturity securities was $2.403 billion. These securities are subject primarily to interest rate risk and credit risk. We have not and currently do not intend to enter into derivative transactions.
Interest Rate Risk
Our fixed maturities portfolio is exposed to interest rate risk. Fluctuations in interest rates have a direct impact on the market valuation of these securities. As interest rates rise, market values of fixed income portfolios fall and vice versa. We believe we are in a position to keep our fixed income investments until maturity as we do not invest in fixed maturity securities for trading purposes.

At December 31, 2005, the fair value of our investment in preferred stocks was $2.0 million, including net unrealized gains of $25 thousand. Preferred stocks are primarily subject to interest rate risk because they bear a fixed rate of return. The investments in the above table do not include preferred stocks.
Computations of prospective effects of hypothetical interest rate changes are based on numerous assumptions, including the maintenance of the existing level and composition of fixed income security assets, and should not be relied on as indicative of future results.
Certain shortcomings are inherent in the method of analysis presented in the computation of the fair value of fixed rate instruments. Actual values may differ from those projections presented should market conditions vary from assumptions used in the calculation of the fair value of individual securities, including non-parallel shifts in the term structure of interest rates and changing individual issuer credit spreads.
ProAssurance’s cash and short-term investment portfolio at December 31, 2005 was on a cost basis which approximates its fair value. This portfolio lacks significant interest rate sensitivity due to its short duration.

##### Table of Contents

Credit Risk
We have exposure to credit risk primarily as a holder of fixed income securities. We control this exposure by emphasizing investment grade credit quality in the fixed income securities we purchase.
As of December 31, 2005, 98.4% of our fixed income portfolio consisted of securities rated investment grade. We believe that this concentration in investment grade securities reduces our exposure to credit risk on these fixed income investments to an acceptable level. However, in the current environment even investment grade securities can rapidly deteriorate and result in significant losses.
Equity Price Risk
At December 31, 2005 the fair value of our investment in common stocks was $13.2 million. These securities are subject to equity price risk, which is defined as the potential for loss in market value due to a decline in equity prices. The weighted average Beta of this group of securities is 0.95. Beta measures the price sensitivity of an equity security or group of equity securities to a change in the broader equity market, in this case the S&P 500 Index. If the value of the S&P 500 Index increased by 10%, the fair value of these securities would be expected to increase by 9.5% to $14.4 million. Conversely, a 10% decrease in the S&P 500 Index would imply a decrease of 9.5% in the fair value of these securities to $11.9 million. The selected hypothetical changes of plus or minus 10% do not reflect what could be considered the best or worst case scenarios and are used for illustrative purposes only.

fiscal quarter then ended that has materially effected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting, other than as described below.
Our management excluded NCRIC’s systems and processes from the scope of our assessment of internal control over financial reporting as of December 31, 2005 in reliance on the guidance set forth in Question 3 of a “Frequently Asked Questions” interpretive release issued by the staff of the Securities and Exchange Commission’s Office of the Chief Accountant and the Division of Corporation Finance in June 2004 (and revised on October 6, 2004). We are excluding NCRIC from that scope because we expect substantially all of its significant systems and processes to be converted to those ProAssurance during 2006. At December 31, 2005 NCRIC represented $298 million or 8.9% of total assets from continuing operations, and $32.4 million or 5.0% of total revenues for the year then ended.
Management’s assessment of the effectiveness of our internal control over financial reporting as of December 31, 2005 has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which is included elsewhere herein.

Report of Independent Registered Public Accounting Firm on
Internal Control over Financial Reporting
The Board of Directors and Shareholders of ProAssurance Corporation
We have audited management’s assessment, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting, that ProAssurance Corporation and subsidiaries maintained effective internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). ProAssurance Corporation’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the company’s internal control over financial reporting based on our audit.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
As indicated in the accompanying Management’s Annual Report on Internal Control over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of NCRIC Corp. and subsidiaries (NCRIC). NCRIC was acquired August 3, 2005 and has been included in the consolidated financial statements of ProAssurance Corporation since that date. NCRIC constituted approximately 8.9% of total assets from continuing operations as of December 31, 2005 and approximately 5.0% of total revenues for the year then ended. Our audit of internal control over financial reporting of ProAssurance Corporation also did not include an evaluation of the internal control over financing reporting of NCRIC Corp. and subsidiaries.
In our opinion, management’s assessment that ProAssurance Corporation and subsidiaries maintained effective internal control over financial reporting as of December 31, 2005, is fairly stated, in all material respects, based on the COSO criteria. Also, in our opinion, ProAssurance Corporation and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2005, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of ProAssurance Corporation and subsidiaries as of December 31, 2005 and 2004, and the related consolidated statements of income, changes in capital and cash flow for each of the three years in the period ended December 31, 2005, and our report dated February 27, 2006 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm
on Consolidated Financial Statements
To the Board of Directors and Shareholders of
ProAssurance Corporation
We have audited the accompanying consolidated balance sheets of ProAssurance Corporation and subsidiaries as of December 31, 2005 and 2004, and the related consolidated statements of changes in capital, income and cash flow for each of the three years in the period ended December 31, 2005. Our audits also included the financial statement schedules listed in the Index at Item 15(a). These financial statements and schedules are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedules based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of ProAssurance Corporation and subsidiaries at December 31, 2005 and 2004, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2005, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedules, when considered in relation to the basic financial statements taken as a whole, present fairly in all material respects the information set forth therein.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of ProAssurance Corporation’s internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 27, 2006 expressed an unqualified opinion thereon.

Notes to Consolidated Financial Statements

1. Accounting Policies
Organization and Nature of Business
ProAssurance Corporation (ProAssurance), a Delaware corporation, is an insurance holding company for specialty property and casualty insurance companies that principally provides professional liability insurance for providers of health care services, and to a lesser extent, providers of legal services. ProAssurance operates in the United States of America (U.S.), principally in the mid-Atlantic, Midwest and Southeast. After giving consideration to the disposal of the personal lines segment (see below), ProAssurance’s operations are in a single reportable segment, the professional liability segment.
Segment Information / Discontinued Operations
In the first quarter of 2006 ProAssurance sold its Personal Lines Division consisting of its wholly owned subsidiaries, MEEMIC Insurance Company, Inc. and MEEMIC Insurance Services (collectively, the MEEMIC Companies). The MEEMIC Companies are the only active entities of ProAssurance’s personal lines operations, which were formerly considered as a separate reportable industry segment. In accordance with Statement of Financial Accounting Standard (SFAS) No. 144 Accounting for the Impairment or Disposal of Long-lived Assets, ProAssurance’s personal lines operations have been classified in this report as discontinued operations in all periods presented. See Note 3 for further discussion of discontinued operations.
Principles of Consolidation
The accompanying consolidated financial statements include the accounts of ProAssurance Corporation and its subsidiaries. All significant intercompany accounts and transactions between consolidated companies have been eliminated.
Basis of Presentation
The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Reclassifications
The benefit of ceding commission on certain reinsurance contracts has been reclassified in the prior year financial statements to conform to the current year presentation. The reclassification decreased premiums ceded and increased underwriting, acquisition and insurance expenses by $7.3 million for 2004 and $6.7 million for 2003, and had no impact on income from continuing operations in either period.
Critical Accounting Policies
The significant accounting policies followed by ProAssurance that materially affect financial reporting are summarized in these notes to the consolidated financial statements.

Investments
Fixed Maturities and Equity Securities Available for Sale
ProAssurance considers all fixed maturity securities as available-for-sale. Equity securities are considered as either available-for-sale or trading portfolio securities. Available-for-sale securities are carried at fair value, and unrealized gains and losses on such available-for-sale securities are excluded from earnings and included, net of related tax effects, in stockholders’ equity as “Accumulated other comprehensive income (loss)” until realized.
Fair values for fixed maturity and equity securities are based on quoted market prices, where available. For fixed maturity and equity securities not actively traded, fair values are estimated using values obtained from independent pricing services.
Investment income includes amortization of premium and accretion of discount related to debt securities acquired at other than par value. Debt securities and mandatorily redeemable preferred stock with maturities beyond one year when purchased are classified as fixed maturities.
Equity Securities, Trading Portfolio
ProAssurance has designated certain equity security purchases as trading portfolio securities. A trading portfolio is carried at fair value with the holding gains and losses included in realized investment gains and losses in the current period. Fair values are based on quoted market prices.
Real Estate
Real estate properties are classified as investment real estate. All balances are reported at cost, less allowances for depreciation. Depreciation is computed over the estimated useful lives of the related property using the straight-line method. Rental income and expenses are included in net investment income.
Short-term Investments
Short-term investments, which have an original maturity of one year or less, are primarily comprised of investments in U.S. Treasury obligations and commercial paper. All balances are reported at cost, which approximates fair value.
Other Investments
Other investments are primarily comprised of equity interests in non-public investment partnerships/limited liability companies. Interests where ProAssurance has virtually no influence over the operating and financial policies of the entity and for which there is no readily determinable fair value are accounted for using the cost method. Interests where ProAssurance has a greater than minor interest in the entity are accounted for using the equity method.
Business Owned Life Insurance (BOLI)
ProAssurance owns life insurance contracts on certain key management employees. The life insurance contracts are carried at their current cash surrender value. Changes in the cash surrender value are included in income in the current period as investment income. Death proceeds from the contracts are recorded when the proceeds become payable under the policy terms.

Cash and Cash Equivalents
For purposes of the consolidated balance sheets and statements of cash flow, ProAssurance considers all demand deposits and overnight investments to be cash equivalents.
Realized Gains and Losses
Realized gains and losses on sales of investments are recognized on the specific identification basis.
Other-than-temporary Impairments
In accordance with SFAS No. 115, “Accounting for Certain Investments in Debt and Equity Securities,” ProAssurance evaluates its investment securities on at least a quarterly basis for declines in market value below cost for the purpose of determining whether these declines represent other than temporary declines. A decline in the fair value of a security below cost judged to be other than temporary is recognized as a loss in the then current period and reduces the cost basis of the security. In subsequent periods, ProAssurance measures any gain or loss or decline in value against the adjusted cost basis of the security. The following factors are considered in determining whether an investment’s decline is other than temporary:

– |  | the extent to which the market value of the security is less than its cost basis,
– |  | the length of time for which the market value of the security has been less than its cost basis,
– |  | the financial condition and near-term prospects of the security’s issuer, taking into consideration the economic prospects of the issuer’s industry and geographical region, to the extent that information is publicly available, and
– |  | ProAssurance’s ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value.

Reinsurance
ProAssurance enters into reinsurance agreements whereby other insurance entities agree to assume a portion of the risk associated with the policies issued by ProAssurance. In return, ProAssurance agrees to pay a premium to the reinsurer. ProAssurance purchases (cedes) reinsurance to provide for greater diversification of business, allow management to control exposure to potential losses arising from large risks, and provide additional capacity for growth.
Receivable from reinsurers is the estimated amount of future loss payments that will be recoverable from reinsurers. Reinsurance recoveries are the portion of losses incurred during the period that are estimated to be allocable to reinsurers. Premiums ceded are the estimated premiums that will be due to reinsurers with respect to premiums earned and losses incurred during the period.
These estimates are based upon management’s estimates of ultimate losses and the portion of those losses that are allocable to reinsurers under the terms of the related reinsurance agreements. Given the uncertainty of the ultimate amounts of losses, these estimates may vary significantly from the eventual outcome. Management regularly reviews these estimates and any adjustments necessary are reflected in the period in which the estimate is changed. Due to the size of the receivable from reinsurers, even a small adjustment to the estimates could have a material effect on ProAssurance’s results of operations for the period in which the change is made.
Reinsurance contracts do not relieve ProAssurance from its obligations to policyholders. ProAssurance continually monitors its reinsurers to minimize its exposure to significant losses from reinsurer insolvencies. Any amount found to be uncollectible is written off in the period in which the uncollectible amount is identified.

Goodwill
Intangible assets consist primarily of the excess of cost over the fair value of net assets acquired (i.e., goodwill). In accordance with SFAS No. 142, “Goodwill and Other Intangible Assets”, goodwill is not amortized. Goodwill is tested annually for impairment. ProAssurance regularly reviews its goodwill and other intangibles to determine if any adverse conditions exist that could indicate impairment. Conditions that could trigger impairment include, but are not limited to, a significant adverse change in legal factors or business climate that could affect the value of an asset or an adverse action or assessment by a regulator. ProAssurance does not believe that any of its recorded goodwill or intangible assets has suffered impairment. Goodwill is included in the Consolidated Balance Sheets as a component of other assets.
Deferred Policy Acquisition Costs
Costs that vary with and are directly related to the production of new and renewal premiums (primarily premium taxes, commissions and underwriting salaries) are deferred to the extent they are recoverable against unearned premiums and are amortized as related premiums are earned. Deferred Policy Acquisition Costs are included in the Consolidated Balance Sheets as a component of other assets.
Reserve for Losses and Loss Adjustment Expenses (Reserve for Losses)
ProAssurance establishes its reserve for loss and loss adjustment expenses (reserve for losses) based on estimates of the future amounts necessary to pay claims and expenses (losses) associated with the investigation and settlement of claims. The reserve for losses is determined on the basis of individual claims and payments thereon as well as actuarially determined estimates of future losses based on past loss experience, available industry data and projections as to future claims frequency, severity, inflationary trends, judicial trends, legislative changes and settlement patterns.
ProAssurance believes that the methods it uses to establish the reserve for losses are reasonable and appropriate. External actuaries review the reserve for losses of each insurance subsidiary at least semi-annually. ProAssurance considers the views of the external actuaries as well as other factors, such as known, anticipated or estimated changes in frequency and severity of claims, loss retention levels and premium rates in establishing its reserves. Estimating casualty insurance reserves, and particularly liability reserves, is a complex process. Claims may be resolved over an extended period of time, often five years or more, and may be subject to litigation. Estimating losses for liability claims requires ProAssurance to make and revise judgments and assessments regarding multiple uncertainties over an extended period of time. As a result, reserve estimates may vary significantly from the eventual outcome. Reserve estimates and the assumptions on which these estimates are predicated are regularly reviewed and updated as new information becomes available. Any adjustments necessary are reflected in then current operations. Due to the size of ProAssurance’s reserve for losses, even a small percentage adjustment to these estimates could have a material effect on earnings in the period in which the adjustment is made.
The effect of adjustments made to reinsured losses is mitigated by the corresponding adjustment that is made to reinsurance recoveries. Thus, in any given year, the Company may make significant adjustments to gross losses that have little effect on its net losses.
Recognition of Revenues
Insurance premiums are recognized as revenues pro rata over the terms of the policies.

Income Taxes
ProAssurance files a consolidated federal income tax return. Deferred income taxes are provided for temporary differences between financial and income tax reporting relating primarily to unrealized gains on securities, discounting of losses for income tax reporting, and the limitation of the unearned premiums deduction for income tax reporting.

Accounting Changes
On December 16, 2004 the Financial Accounting Standards Board (FASB) issued SFAS 123 (revised 2004), Share-Based Payment, hereafter referred to as SFAS 123(R), which is a revision of SFAS 123, Accounting for Stock-Based Compensation (SFAS 123), which superseded APB 25, Accounting for Stock Issued to Employees (APB 25), and amends SFAS 95, Statement of Cash Flows. The provisions of SFAS 123(R) require all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values. SFAS 123(R) also requires that the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow, rather than as an operating cash flow as required under current literature. ProAssurance plans to adopt SFAS 123(R) on January 1, 2006, the required effective date, using the “modified prospective” method permitted by the statement and will value future grants of stock options using the Black Scholes valuation method.
Under the “modified prospective” method stock-based compensation is recognized under the requirements of SFAS 123(R) for all share-based payments granted after the effective date of SFAS 123(R) and for the non-vested portion of share-based payments granted prior to the adoption of SFAS 123(R). Under SFAS 123(R) compensation for non-vested share-based payments granted prior to adoption shall continue to be calculated as disclosed under SFAS 123, except that the effect of forfeitures is required to be estimated rather than considered as forfeitures occur.
As permitted by SFAS 123, ProAssurance currently values employee stock-based payments using APB 25’s intrinsic value method. Accordingly, ProAssurance generally recognizes no compensation cost related to such payments but does provide pro forma disclosure of the effect on net income and earnings per share of applying the fair value provisions of SFAS 123 to such payments granted.
Had ProAssurance’s SFAS 123 pro forma disclosures been prepared in accordance with the provisions of SFAS 123(R) the effect would have been different; however, the effect that SFAS 123(R) would have had on prior periods is not readily determinable. SFAS 123(R) provides more extensive guidance than does SFAS 123 with regard to factors that should be considered in valuing share-based payments. Under SFAS 123, ProAssurance utilized a single set of valuation assumptions for all employees. Under SFAS 123(R), entities are required to “aggregate individual awards into relatively homogeneous groups with respect to exercise and post-vesting employment termination behaviors.” Accordingly, ProAssurance anticipates aggregating prospective awards into groups consisting of senior executives likely to exercise shortly after vesting, other senior executives and other employees to appropriately reflect differing exercise and post-vesting employee termination behaviors. Additionally, under SFAS 123(R), fully vested awards granted to directors and awards that vest upon retirement granted to employees who are eligible for retirement will be expensed on the date of grant. Under SFAS 123, ProAssurance calculated compensation expense (for pro forma disclosure) without consideration of expected forfeitures. Unlike SFAS 123, which permitted companies to reflect forfeitures as they occurred, SFAS 123(R) requires companies to estimate forfeitures in determining the amount of compensation cost to recognize each period. As a result, ProAssurance will develop estimates of forfeitures during the requisite service periods and revise previous SFAS 123 calculations for known and expected forfeitures related to grants prior to the adoption of SFAS 123(R). ProAssurance’s own history with regard to the expected terms of employee stock awards is not sufficient to allow such assumptions to be developed statistically for most employee groups. Accordingly, through December 31, 2007, ProAssurance will apply the “simplified” method consistent with the guidance of SEC Staff Accounting Bulletin 107, i.e., expected term = (vesting term + original contractual term) / 2) for such groups. ProAssurance is in the process of finalizing these assumptions; however, the selection of all assumptions is not complete.
Presently, ProAssurance estimates that the recognition of compensation cost, net of related tax effects, for the non-vested portion of share-based payments granted prior to the adoption of SFAS 123(R) will approximate $1.3 million during fiscal 2006. The further effect of adoption of SFAS 123(R) on future operating results will depend on the levels of share-based payments granted in the future, the groups of employees to whom the awards are granted, the number of awards granted to employees who are eligible for retirement, the

terms of any future awards, as well as the final methods and assumptions used to determine the fair value of those share-based payments.
The FASB issued SFAS 154, Accounting Changes and Error Corrections, in May 2005 as a replacement of APB 20, Accounting Changes, and SFAS 3, Reporting Accounting Changes in Interim Financial Statements. SFAS 154 applies to voluntary changes in accounting principle and changes the requirements for accounting for and reporting of a change in accounting principle and is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. ProAssurance expects to adopt SFAS 154 on its effective date.

2. Acquisition of NCRIC
ProAssurance acquired 100% of the outstanding shares of NCRIC Corporation (NCRIC) on August 3, 2005 primarily for the purpose of expanding the distribution of its professional liability insurance products. NCRIC, formerly known as NCRIC Group, Inc., is a holding company primarily focused on providing medical professional liability insurance in Delaware, the District of Columbia, Maryland, Virginia, and West Virginia. A summary of the components of the aggregate purchase price and a summary of the fair value of net assets acquired follows (in thousands):

Aggregate Purchase Price: |  |  |  |
Fair value of 1.7 million ProAssurance common shares issued, based on a fair value of $40.54 per share |  | $ | 67,066 |
Fair value of NCRIC options exchanged, estimated using the Black Scholes valuation method |  |  | 192 |
Cash paid for NCRIC options in lieu of exchange |  |  | 775 |
Acquisition costs (primarily fees paid for legal, accounting and financial advisory services) |  |  | 1,910 |
Estimated benefits payable under termination agreements provided to NCRIC employees |  |  | 1,216 |
Aggregate purchase price |  | $ | 71,159 |
Fair Value of Net Assets: |  |  |  |
Fixed maturities available for sale, at fair value |  | $ | 184,945 |
Equity securities available for sale, at fair value |  |  | 27,842 |
Reinsurance recoverable |  |  | 43,486 |
Other assets |  |  | 58,939 |
Reserves for losses and loss adjustment expenses |  |  | (183,158 | )
Other policy liabilities |  |  | (40,906 | )
Long-term debt |  |  | (15,464 | )
Liability for judgment (Note 9) |  |  | (19,500 | )
Other liabilities |  |  | (10,019 | )
Net assets acquired, at fair value |  | $ | 46,165 |

The fair value per ProAssurance share is based on the average ProAssurance common stock price for three days before and after February 28, 2005 (the date the terms of the acquisition were agreed to and publicly announced). The acquisition has been accounted for as a purchase transaction in accordance with SFAS 141 and the purchase price has been allocated to the assets acquired and liabilities assumed based on estimates of their respective fair values at the date of acquisition. Goodwill of $25.0 million was recognized equal to the excess of the purchase price over the fair values of the identifiable net assets acquired. The goodwill is not expected to be tax deductible.
The fair value of NCRIC’s reserve for losses and loss adjustment expenses and related reinsurance recoverables were estimated based on the present value of the expected underlying cash flows of the loss reserves and reinsurance recoverables, and include a risk premium and a profit margin. In determining the fair value estimate, management discounted NCRIC’s historical undiscounted net loss reserves to present value assuming a discount rate of 4.3%, which approximates the ten year treasury rate. The discounting pattern was actuarially developed from NCRIC’s historical loss data. An expected profit margin of 5% was applied to the discounted loss reserves, which is consistent with management’s understanding of the returns anticipated by the reinsurance market (the reinsurance market representing a willing partner in the purchase of loss reserves). Additionally, in consideration of the long-tail nature and the related high degree of uncertainty of such reserves, an estimated risk premium of 5% was applied to the discounted reserves. The above calculations resulted in a fair value which was not materially different

than NCRIC’s historical reserves and therefore did not result in an adjustment to NCRIC’s carried reserve for loss and loss adjustment expense.
ProAssurance’s Consolidated Statement of Income for the year ended December 31, 2005 includes NCRIC activity commencing upon August 3, 2005, the effective date of the acquisition. The unaudited pro forma information below presents combined results of operations as if the acquisition had occurred at the beginning of the respective periods, and includes the effect of adjusting NCRIC’s assets and liabilities to fair value on the date of acquisition. The pro forma results for the year ended December 31, 2005 include non-recurring and transaction related expenses of $4.3 million, related to compensation costs and professional fees, $8.7 million of unfavorable prior year loss development and $19.5 million related to a loss contingency (see also Note 9).
The following unaudited pro forma information is not necessarily indicative of the results of operations of the combined company had the acquisition occurred at the beginning of the periods presented, nor is it necessarily indicative of future results.

On December 28, 2005, ProAssurance sold ConsiCare, a non-insurance subsidiary acquired August 3, 2005 in the NCRIC transaction, for approximately $1.7 million (cash of $0.8 million and note receivable of $0.9 million). No gain or loss was recognized related to the sale because the carrying value for ConsiCare net assets approximated the sales price less sale expenses. In accordance with SFAS 144 “Accounting for the Impairment or Disposal of Long-Lived Assets” (SFAS 144), ConsiCare’s results of operations since acquisition are reported as a component of discontinued operations, as follows:

3. Discontinued Operations (continued)
On November 4, 2005 ProAssurance entered into a definitive agreement to sell its wholly owned subsidiaries, MEEMIC Insurance Company, Inc. and MEEMIC Insurance Services (collectively, the MEEMIC Companies) to Motors Insurance Corporation (Motors), a subsidiary of GMAC Insurance Holdings, Inc., for total consideration of $400 million ($325 million from Motors and $75 million in dividends from the MEEMIC Companies), before transaction expenses. The sale, which was approved by the Michigan Insurance Department, was completed on January 4, 2006, with an effective date of January 1, 2006. ProAssurance expects to recognize a gain on the sale in 2006 of approximately $110 million after consideration of sale expenses and tax effects.
The MEEMIC Companies are the only active entities of ProAssurance’s personal lines operations. In accordance with SFAS 144, the Consolidated Financial statements reflect the assets, liabilities and operating results attributed to ProAssurance’s personal lines operations as discontinued operations.

After an evaluation of each security, Management concluded that these securities have not suffered an other than temporary impairment in value. Of the unrealized losses aggregated in the above table, over 95% are considered to be interest rate related. Each fixed maturity security has paid all scheduled contractual payments. Management believes that each issuer has the capacity to meet the remaining contractual obligations of the security, including payment at maturity, and that ProAssurance has the current ability and intent to hold the security until either the scheduled maturity date or the security recovers in value. In total, there are approximately 1,100 securities in a loss position. Management considers the loss on 7 of those securities to be credit related; the total losses related to these securities total $1.3 million. The single greatest credit-related loss position approximates $750,000; the second greatest credit-related loss position is a loss of approximately $180,000. Management also believes each of the equity securities, given the characteristics of the underlying company, industry, and price volatility of the security, has a reasonable probability of being valued at or above book value in the near term.
The amortized cost and estimated fair value of fixed maturities at December 31, 2005, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. ProAssurance uses the call date as the contractual maturity for prerefunded state and municipal bonds which are 100% backed by U.S. Treasury obligations.

Excluding investments in bonds and notes of the U.S. Government, a U.S. Government agency, or prerefunded state and municipal bonds which are 100% backed by U.S. Treasury obligations, no investment in any person or its affiliates exceeded 10% of stockholders’ equity at December 31, 2005.
At December 31, 2005 ProAssurance had available-for-sale securities with a carrying value of $11.9 million on deposit with various state insurance departments to meet regulatory requirements.
Business Owned Life Insurance
During 2003 ProAssurance purchased BOLI policies on executive employees at a cost of approximately $50 million. The primary purpose of the program is to offset future employee benefit expenses through earnings on the cash value of the policies. ProAssurance is the owner and principal beneficiary of these policies; however, $50,000 of each death benefit is payable to beneficiaries designated by the insured employee.
Real Estate
Real estate consists of two properties currently in use as corporate offices. One property includes 78,000 square feet of office space which is leased or available for lease. Balances are net of accumulated depreciation of approximately $9.9 million and $9.8 million at December 31, 2005 and 2004, respectively. Real estate depreciation expense for the three years ended December 31, 2005, 2004 and 2003 is $1.2 million, $1.1 million and $1.0 million, respectively.

5. Reinsurance
ProAssurance has various quota share, excess of loss, and cession reinsurance agreements. Historically, professional liability per claim retention levels have varied between the first $200,000 and the first $2 million depending on the coverage year and the state in which business was written. ProAssurance also insures some large professional liability risks that are above the limits of its basic reinsurance treaties. These risks are reinsured on a facultative basis, whereby the reinsurer agrees to insure a particular risk up to a designated limit.
The effect of reinsurance on premiums written and earned is as follows:

Reinsurance contracts do not relieve ProAssurance from its obligations to policyholders. A contingent liability exists with respect to reinsurance ceded to the extent that any reinsurer does not meet the obligations assumed under the reinsurance agreements. ProAssurance continually monitors its reinsurers to minimize its exposure to significant losses from reinsurer insolvencies.
At December 31, 2005, all reinsurance recoverables are considered collectible. Reinsurance recoverables totaling approximately $36.4 million are collateralized by letters of credit or funds withheld.
At December 31, 2005 amounts due from individual reinsurers that exceed 5% of stockholders’ equity are as follows:

|  | Amount Due |
|  | From Reinsurer |
Reinsurer |  | In millions |
Hannover Ruckversicherung AG |  | $ | 59.7 |

During 2004, ProAssurance commuted (terminated) its various agreements with one of its reinsurers, Gerling Global Reinsurance Corporation of America. As a result of that commutation, ProAssurance reduced its receivable from reinsurers by approximately $5.5 million (net of $11.9 million cash received) and reduced its reinsurance liabilities by approximately $1.6 million, resulting in a net loss on the commutation of approximately $3.9 million.

6. Income Taxes
Deferred income taxes reflect the net tax effects of temporary differences between the amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of ProAssurance’s deferred tax liabilities and assets are as follows:

|  | 2005 |  |  | 2004 |

Deferred tax assets |  |  |  |  |  |  |  |
Unpaid loss discount |  | $ | 77,049 |  |  | $ | 70,025 |

Net deferred tax assets |  | $ | 103,935 |  |  | $ | 69,630 |

In management’s opinion, it is more likely than not that ProAssurance will realize the benefit of the deferred tax assets, and therefore, no valuation allowance has been established.
ProAssurance, after adjustment for its tax liability for the year ended December 31, 2005, has available net operating loss (NOL) carryforwards of $9.6 million and Alternative Minimum Tax (AMT) credit carryforwards of $634,000. The NOL carryforwards will expire in 2019; the AMT credit carryforwards have no expiration date. The AMT carryforwards can be applied against any future regular tax payable.

7. Deferred Policy Acquisition Costs
Underwriting and insurance costs directly related to the production of new and renewal premiums are considered as acquisition costs and are capitalized and amortized to expense over the period in which the related premiums are earned. Reinsurance ceding commissions due ProAssurance are considered as a reduction of acquisition costs, and therefore reduce the total amount capitalized.
Amortization of deferred acquisition costs amounted to approximately $54.0 million, $52.8 million, and $45.2 million for the years ended December 31, 2005, 2004 and 2003, respectively. Unamortized deferred acquisition costs are included in other assets on the Consolidated Balance Sheets and amounted to approximately $22.3 million and $21.3 million at December 31, 2005 and 2004, respectively.
8. Reserve for Losses and Loss Adjustment Expenses
ProAssurance establishes its reserve for losses based on estimates of the future amounts necessary to pay claims and expenses associated with the investigation and settlement of claims. These estimates consist of case reserves and bulk reserves. Case reserves are estimates of future losses for reported claims and are established by ProAssurance’s claims department. Bulk reserves, which include a provision for losses that have occurred but have not been reported to ProAssurance and reserves for the potential aggregate development of known claims, are the difference between (i) the sum of case reserves and paid losses and (ii) an actuarially determined estimate of the total losses necessary for the ultimate settlement of all reported and incurred but not reported claims, including amounts already paid.
The reserve for losses is established based on estimates of individual claims and actuarially determined estimates of future losses based on ProAssurance’s past loss experience, available industry data and projections as to future claims frequency, severity, inflationary trends and settlement patterns. Estimating reserves, and particularly liability reserves, is a complex process. Claims may be resolved over an extended period of time, often five years or more, and may be subject to litigation. Estimating losses for liability claims requires ProAssurance to make and revise judgments and assessments regarding multiple uncertainties over an extended period of time. As a result, reserve estimates may vary significantly from the eventual outcome. The assumptions used in establishing ProAssurance’s reserves are regularly reviewed and updated by management as new data becomes available. Changes to estimates of previously established reserves are included in earnings in the period in which the estimate is changed.
ProAssurance believes that the methods it uses to establish reserves are reasonable and appropriate. Each year, ProAssurance uses external actuaries to review the reserve for losses of each insurance subsidiary. ProAssurance considers the views of the external actuaries as well as other factors, such as known, anticipated or estimated changes in frequency and severity of claims and loss retention levels and premium rates, in establishing the amount of its reserve for losses. The statutory filings of each insurance company with the insurance regulators must be accompanied by an actuary’s certification as to their respective reserves in accordance with the requirements of the National Association of Insurance Commissioners (NAIC).

8. Reserve for Losses and Loss Adjustment Expenses (continued)
Activity in the reserve for losses and loss adjustment expenses is summarized as follows:

|  | 2005 |  |  | 2004 |  |  | 2003 |
|  | In thousands |
Balance, beginning of year |  | $ | 1,818,636 |  |  | $ | 1,634,749 |  |  | $ | 1,494,875 |

Total paid |  |  | (226,112 | ) |  |  | (213,913 | ) |  |  | (239,851 | )
Net balance, end of year |  |  | 1,896,743 |  |  |  | 1,544,982 |  |  |  | 1,298,458 |
Plus reinsurance recoverables |  |  | 327,693 |  |  |  | 273,654 |  |  |  | 336,291 |
Balance, end of year |  | $ | 2,224,436 |  |  | $ | 1,818,636 |  |  | $ | 1,634,749 |

As discussed in Note 1, estimating liability reserves is complex and requires the use of many assumptions. As time passes and ultimate losses for prior years are either known or become subject to a more definite estimation, ProAssurance increases or decreases the reserve estimates established in prior periods. The favorable development of $23.0 million recognized in 2005 was due to reductions in our estimates of claim severity. The most significant reduction was recognized related to the 2003 accident year, however favorable development was also seen in accident years 2002 and prior. The favorable development recognized in 2004 primarily reflected small improvements in claims severity for accident years 2002 and prior.

9. Commitments and Contingencies
As a result of the acquisition of NCRIC, ProAssurance assumed the risk of loss for a judgment entered against NCRIC on February 20, 2004 by a District of Columbia Superior Court in favor of Columbia Hospital for Women Medical Center, Inc. (“CHW”) in the amount of $18.2 million (the “CHW Judgment”). By order of September 30, 2005, the trial court denied all post-trial relief sought by NCRIC and NCRIC has appealed the judgment. NCRIC posted a $19.5 million appellate bond and associated letter of credit to secure payment of the CHW judgment plus interest and costs, in the event the judgment is ultimately affirmed and paid. In accordance with SFAS 141, ProAssurance established a liability of $19.5 million for this judgment and included the liability as a component of the fair value of assets acquired and liabilities assumed in the allocation of the NCRIC purchase price.
ProAssurance is involved in various other legal actions arising primarily from claims against itself related to insurance policies and claims handling, including but not limited to claims asserted by policyholders. The legal actions arising from these claims have been considered by ProAssurance in establishing its reserves. While the outcome of all legal actions is not presently determinable, ProAssurance’s management is of the opinion, based on consultation with legal counsel, that the resolution of these actions will not have a material adverse effect on ProAssurance’s financial position. However, to the extent that the cost of resolving these actions exceeds the corresponding reserves, the legal actions could have a material effect on ProAssurance’s results of operations for the period in which any such action is resolved.
ProAssurance is involved in a number of operating leases primarily for office space, office equipment, and communication lines. The following is a schedule of future minimum lease payments for operating leases that had initial or remaining noncancelable lease terms in excess of one year as of December 31, 2005.

Operating Leases

2009 |  |  | 409 |
Thereafter |  |  | 256 |
Total minimum lease payments |  | $ | 6,594 |

ProAssurance incurred rent expense of $2.4 million, $1.9 million and $2.0 million in the years ended December 31, 2005, 2004 and 2003, respectively.
On December 8, 2005 ProAssurance and Physicians Insurance Company of Wisconsin, Inc. (“PIC Wisconsin”) reached a definitive agreement whereby ProAssurance has agreed to acquire PIC Wisconsin in an all stock merger transaction, having an estimated value of $100 million. Under terms of the agreement, each share of PIC Wisconsin stock will be converted into shares of ProAssurance stock having a value of $5,000. The exchange ratio is based on the average closing price of a share of ProAssurance stock on the ten trading days preceding the effective date of the merger. This ratio is subject to a 20% range around $49.76, which is the average closing price in the ten days preceding the date of the definitive agreement. Thus, PIC Wisconsin shareholders may receive more than $5,000 for each share of stock if the average closing price of ProAssurance stock is more than $59.71; conversely, PIC Wisconsin shareholders may receive less than $5,000 per share if the average closing price of ProAssurance stock is less than $39.80. The transaction is subject to required regulatory approvals and a vote of PIC Wisconsin stockholders and is expected to close in the latter half of 2006.

|  |  |  |  |  | $ | 167,240 |  |  | $ | 151,480 |

Convertible Debentures Due June 30, 2023 (the Convertible Debentures)
The Convertible Debentures were issued by ProAssurance in July 2003 in a Private Offering transaction, net of an initial purchaser’s discount of $3.0 million. ProAssurance used the net proceeds to pay off its existing term loan having an outstanding principal balance of $67.5 million.
Summarized information regarding the structure and terms of the Convertible Debentures follows:
Issue Price. The Convertible Debentures were issued at 100.0% of their principal amount and each Convertible Debenture has a principal amount at maturity of $1,000.
Maturity Date. June 30, 2023.
Ranking. The Convertible Debentures are unsecured obligations and rank equally in right of payment with all other existing and future unsecured and unsubordinated obligations. The Convertible Debentures are not guaranteed by any of ProAssurance’s subsidiaries and, accordingly, the Convertible Debentures are effectively subordinated to the indebtedness and other liabilities of ProAssurance’s subsidiaries, including insurance policy-related liabilities.
Interest. Interest is payable on June 30 and December 30 of each year, beginning December 30, 2003, at an annual rate of 3.90%. In addition, ProAssurance may be required to pay contingent interest, as set forth below under Contingent Interest.
Contingent Interest. Contingent interest is due to the holders of the Convertible Debentures during any six-month period from June 30 to December 29 and from December 30 to June 29 commencing with the six-month period beginning June 30, 2008, if the average market price of a Convertible Debenture for the five trading days ending on the second trading day immediately preceding the relevant six-month period equals 120% or more of the principal amount of the Convertible Debentures. The amount of contingent interest payable in respect of any six-month period will equal 0.1875% of the average market price of a Convertible Debenture for the five trading day period referred to above.

10. Long-term Debt (continued)
Conversion Rights. At December 31, 2005 the Convertible Debentures are not eligible for conversion; however, holders may convert the Convertible Debentures at any time prior to stated maturity from and after the date of the following events:

| – |  | if the sale price of ProAssurance’s common stock for at least 20 trading days in the 30 trading-day period ending on the last trading day of the immediately preceding fiscal quarter exceeds 120% of the conversion price on that 30th trading day,
| – |  | if ProAssurance calls the Convertible Debentures for redemption, or
| – |  | upon the occurrence of certain corporate transactions.

At December 31, 2005 conversion would be at a rate of 23.9037 of shares of common stock for each $1,000 principal amount of Convertible Debentures; this represents a conversion price of approximately $41.83 per share of common stock. The conversion rate is subject to future adjustment should certain corporate events occur, as defined by the related indenture agreement. Upon conversion, holders will generally not receive any cash payment representing accrued interest or contingent interest, if any. Instead, accrued interest and contingent interest will be deemed paid by the common stock received by the holders on conversion. Convertible Debentures called for redemption may be surrendered for conversion until the close of business two business days prior to the redemption date.
Upon conversion, ProAssurance has the right to deliver, in lieu of common stock, cash or a combination of cash and shares of common stock.
Payment at Maturity. Each holder of $1,000 Convertible Debentures will be entitled to receive $1,000 at maturity, plus accrued interest, including contingent interest, if any.
Sinking Fund. None.
Optional Redemption. ProAssurance may not redeem the Convertible Debentures prior to July 7, 2008. ProAssurance may redeem some or all of the Convertible Debentures for cash on or after July 7, 2008, upon at least 30 days but not more than 60 days notice by mail to holders at par.
Repurchase Right of Holders. Each holder of the Convertible Debentures may require ProAssurance to repurchase all or a portion of the holder’s Convertible Debentures on June 30, 2008, June 30, 2013 and June 30, 2018 at a purchase price equal to the principal amount of the Convertible Debentures plus accrued and unpaid interest, including contingent interest, if any, to the date of repurchase. ProAssurance may choose to pay the purchase price in cash, shares of common stock, or a combination of cash and shares of common stock. If ProAssurance elects to pay all or a portion of the repurchase price in common stock, the shares of common stock will be valued at 97.5% of the average sale price for the 20 trading days immediately preceding and including the third day prior to the repurchase date.

10. Long-term Debt (continued)
Change of Control. Upon a change of control of ProAssurance, holders may require ProAssurance, subject to conditions, to repurchase all or a portion of the Convertible Debentures. Depending upon the date at which the change of control occurs, ProAssurance will pay a purchase price equal to a varying percentage of the applicable principal amount of such Convertible Debentures plus accrued and unpaid interest, including contingent interest and additional amounts, if any. The percentage ranges from 104% for dates before June 29, 2006 to 100% for dates after June 30, 2008.
ProAssurance may choose to pay the repurchase price in cash, shares of common stock, shares of common stock of the surviving corporation or a combination of cash and shares of the applicable common stock. If ProAssurance elects to pay all or a portion of the repurchase price in shares of common stock, the shares of the applicable common stock will be valued at 97.5% of the average sale price of the applicable common stock for 20 trading days commencing after the third trading day following notice of the occurrence of a change of control.
Events of Default. If there is an event of default under the Convertible Debentures, the principal amount of the Convertible Debentures, plus accrued interest, including contingent interest, if any, may be declared immediately due and payable. These amounts automatically become due and payable if an event of default relating to certain events of bankruptcy, insolvency or reorganization occurs.
Registration Rights. On December 15, 2003 ProAssurance filed a shelf registration statement with the SEC with respect to the resale of the Convertible Debentures and for the issuance of approximately 2.6 million shares of common stock issuable upon conversion of the Convertible Debentures pursuant to a registration rights agreement.
The Convertible Debentures do not require ProAssurance to maintain minimum financial covenants.
2034 and 2032 Trust Preferred Subordinated Debentures
In April and May 2004, ProAssurance formed two business trusts, (the PRA Trusts) for the sole purpose of issuing, in private placement transactions, $45.0 million of trust preferred securities (PRA TPS) and using the proceeds thereof, together with the equity proceeds received from ProAssurance in the initial formation of the PRA Trusts, to purchase $46.4 million of variable rate subordinated debentures (the 2034 Subordinated Debentures) issued by ProAssurance. ProAssurance owns all voting securities of the PRA Trusts and the 2034 Subordinated Debentures are the sole assets of the PRA Trusts. The PRA Trusts will meet the obligations of the PRA TPS with the interest and principal paid on the 2034 Subordinated Debentures. ProAssurance received net proceeds from the PRA TPS transactions, after commissions and other costs of issuance, of $44.9 million.
In December 2002, NCRIC formed a business trust (the NCRIC Trust), for the sole purpose of issuing, in private placement transactions, $15.0 million of trust preferred securities (NCRIC TPS) and using the proceeds thereof, together with the equity proceeds received from NCRIC in the initial formation of the NCRIC Trust, to purchase $15.5 million of variable rate subordinated debentures (the 2032 Subordinated Debentures) issued by NCRIC. NCRIC owns all voting securities of the NCRIC Trust and the 2032 Subordinated Debentures are the sole assets of the NCRIC Trust. The NCRIC Trust will meet the obligations of the NCRIC TPS with the interest and principal paid on the 2032 Subordinated Debentures.

10. Long-term Debt (continued)
The 2034 and 2032 Subordinated Debentures have the same maturities and other applicable terms and features as the associated trust preferred securities. The 2034 and 2032 Subordinated Debentures are uncollateralized and bear a floating interest rate adjusted quarterly based upon the three-month LIBOR rate, with a maximum rate for the first five years following issuance of 12.5%. Payment of interest may be deferred for up to 20 consecutive quarters; however, stockholder dividends cannot be paid during any extended interest payment period or at any time the debentures are in default. All have stated maturities of thirty years but may be redeemed at any time following the fifth anniversary of issuance. None of the securities require either PRA or NCRIC to maintain minimum financial covenants.
Guarantees
ProAssurance and NCRIC have guaranteed that amounts paid to the PRA and NCRIC Trusts under the associated subordinated debentures (the 2034 and 2032 Subordinated Debentures, respectively) will be remitted to the holders of the associated trust preferred securities. These guarantees, when taken together with the obligations of ProAssurance and NCRIC under their respective debentures, the Indentures pursuant to which those debentures were issued, and the related trust agreements (including obligations to pay related trust cost, fees, expenses, debt and other obligations for the PRA and NCRIC Trusts other than with respect to the common and trust preferred securities of the PRA and NCRIC Trusts), provides a full and unconditional guarantee of amounts due on the PRA and NCRIC TPS. The amounts guaranteed are not expected to at any time exceed the obligations of the 2034 and 2032 Subordinated Debentures, and no additional liability has been recorded related to the PRA and NCRIC TPS or the guarantees.
Fair Value
At December 31, 2005, the fair value of the Convertible Debentures is approximately 125% of face value of $107.6 million based on available independent market quotes. The fair value of the 2034 and 2032 Subordinated Debentures approximates the face value of the debentures.

11. Stockholders’ Equity
At December 31, 2005 ProAssurance had 100 million shares of authorized common stock and 50 million shares of authorized preferred stock. The Board of Directors has the authorization to determine the provisions for the issuance of shares of the preferred stock, including the number of shares to be issued, the designations, powers, preferences and rights, and the qualifications, limitations or restrictions of such shares. At December 31, 2005, the Board of Directors had not authorized the issuance of any preferred stock nor determined any provisions for the preferred stock.
At December 31, 2005 approximately 2.5 million of ProAssurance’s authorized shares of common stock are reserved by the Board of Directors of ProAssurance for the award or issuance of shares under incentive compensation plans as described in Note 12. Additionally, approximately 1.2 million common shares are reserved for the exercise of outstanding options, also discussed in Note 12. Also, see “Registration Rights” in Note 10 (Long-Term Debt) concerning the 2.6 million shares reserved for issuance relative to the Convertible Debentures.

12. Stock Options
ProAssurance provides performance-based stock compensation to employees under the ProAssurance 2004 Equity Incentive Plan and the ProAssurance Corporation Incentive Compensation Stock Plan (the Plans). The terms and conditions of all grants under the Plans are at the discretion of the compensation committee. Options granted under the Plans since 2002 vest at a rate of 20% annually, beginning six months after the grant date. Options granted prior to 2002 were fully vested at the grant date. The exercise price of each option granted is equal to the market price of the stock on the date of grant, and all have an original term of ten years. At December 31, 2005 there were approximately 1.1 million options outstanding under the Plans.
ProAssurance also has approximately 60,000 outstanding options that were issued in conjunction with merger transactions, 12,000 of which resulted from the NCRIC acquisition.

Net income |  | $ | 3.54 |  |  | $ | 2.37 |  |  | $ | 1.33 |

In accordance with SFAS 128 “Earnings per Share”, the diluted weighted average number of shares outstanding includes an incremental adjustment for the assumed exercise of dilutive stock options. The adjustment is computed quarterly; the annual incremental adjustment is the average of the quarterly adjustments. Stock options are considered dilutive stock options if the assumed conversion of the options, using the treasury stock method as specified by SFAS 128, produces an increased number of shares. Options are not dilutive when the exercise price of the option is near to or below the average share price during the quarter. During years ended December 31, 2005, 2004 and 2003 certain of ProAssurance’s outstanding options were not considered to be dilutive because the strike price of the options was below the average ProAssurance share price during the quarter. The average number of options not considered to be dilutive during the years ended December 31, 2005, 2004, and 2003 is approximately 158,000, 126,000 and 84,000, respectively. The conversion of the convertible debentures was not assumed in the 2003 diluted earnings per share computation since the effect of doing so was anti-dilutive.

14. Benefit Plans
ProAssurance currently maintains several defined contribution employee benefit plans that are intended to provide additional income to eligible employees upon retirement. ProAssurance’s expense under these benefit plans was $2.3 million during the year ended December 31, 2005, which includes approximately $72 thousand relating to NCRIC employee benefit plans since the date of acquisition, and $2.2 million and $2.2 million during the years ended December 31, 2004 and 2003, respectively.
15. Statutory Accounting and Dividend Restrictions
ProAssurance’s insurance subsidiaries are required to file statutory financial statements with state insurance regulatory authorities. GAAP differs from statutory accounting practices prescribed or permitted by regulatory authorities. Differences between financial statement net income and statutory net income are principally due to: (a) policy acquisition and certain software and equipment costs which are deferred under GAAP but expensed for statutory purposes; and (b) certain deferred income taxes which are recorded under GAAP but not for statutory purposes.
The NAIC specifies risk-based capital requirements for property and casualty insurance providers. At December 31, 2005, statutory capital for each insurance subsidiary was sufficient to satisfy regulatory requirements. Net earnings and surplus of ProAssurance’s insurance subsidiaries, on a statutory basis, are shown in the following table. Amounts shown exclude MEEMIC Insurance Company which has been sold (see Note 3), and includes the net earnings and surplus of NCRIC Corporation for the twelve months ended December 31, 2005. Consolidated net income, on a GAAP basis, includes the earnings of NCRIC Corporation only since the date of acquisition.

Net Earnings |  | Surplus
2005 |  | 2004 |  | 2003 |  | 2005 |  | 2004
In millions
$ | 69 |  |  | $ | 49 |  |  | $ | 4 |  |  | $ | 726 |  |  | $ | 544 |

Excluding MEEMIC Insurance Company, ProAssurance’s insurance subsidiaries are permitted to pay dividends of approximately $87 million during the next year to ProAssurance or its directly owned non-insurance subsidiaries without prior approval. However, the payment of any dividend requires prior notice to the insurance regulator in the state of domicile and the regulator may prevent the dividend if, in its judgment, payment of the dividend would have an adverse effect on the surplus of the insurance subsidiary.

16. Variable Interest Entities
ProAssurance holds passive investments in various limited partnerships/limited liability companies that are considered to be VIE’s under FIN 46(R) guidance. ProAssurance is not the primary beneficiary relative to these entities and is not required to consolidate the entities under FIN 46(R). These investments, five in total at December 31, 2005, are included in Other Investments and total $42.1 million at December 31, 2005 and $39.3 million at December 31, 2004. The entities are all non-public investment pools formed for the purpose of achieving diversified equity and debt returns. ProAssurance’s maximum loss exposure relative to these investments is limited to the carrying value of ProAssurance’s investment in the entity. ProAssurance’s investment in one of the entities approximates $7.0 million (a 12.9% interest) and is accounted for using the equity method of accounting; this investment was acquired in 2002. ProAssurance’s investment in each of the four remaining entities represents an interest of less than 10% and ProAssurance uses the cost method of accounting for these investments. All were acquired after January 1, 2001.
ProAssurance also holds all the voting securities issued by certain trusts (the PRA and NCRIC Trusts; the Trusts) as discussed in Note 10 and such trusts are considered to be VIE’s. The Trusts are not consolidated because ProAssurance is not the primary beneficiary of these trusts. The 2032 and 2034 Subordinated Debentures are reported in the accompanying Consolidated Balance Sheet as a component of long-term debt. ProAssurance’s equity investments in the Trusts total $1.9 million and are included in Other Assets.

Quarterly and year-to-date computations of per share amounts are made independently; therefore, the sum of per share amounts for the quarters may not equal per share amounts for the year.

(1) |  | Net premiums earned as shown above reflect the reclassification of ceding commissions on certain reinsurance contracts as discussed in Note 1 to the Consolidated Financial Statements under the caption “Reclassifications”. Previously filed reports did not reflect the reclassification. The effect of the reclassification was to increase these amounts by the following (in millions).

2. Long-term Debt
Outstanding long-term debt, as of December 31, 2005 and December 31, 2004, consisted of the following:

|  | December 31
|  | 2005 |  | 2004
|  | $ In thousands
Convertible Debentures due June 30, 2023 (Convertible Debentures), unsecured and bearing a fixed interest rate of 3.9%, net of unamortized original issuer’s discounts of $2,219 and $2,515 at December 31, 2005 and December 31, 2004, respectively. |  | $ | 105,381 |  |  | $ | 105,085 |
Trust Preferred Subordinated Debentures (Subordinated Debentures), unsecured, and bearing floating interest rate, adjustable quarterly, at three-month LIBOR plus 3.85%. |  |  |  |  |  |  |  |

Due |  | December 31, 2005 Rate |  |  |  |  |  |  |  |
April 29, 2034 |  |  | 8.19 | % |  |  | 13,403 |  |  |  | 13,403 |
May 12, 2034 |  |  | 8.19 | % |  |  | 10,310 |  |  |  | 10,310 |
May 12, 2034 |  |  | 8.19 | % |  |  | 22,682 |  |  |  | 22,682 |
|  |  |  |  |  | $ | 151,776 |  |  | $ | 151,480 |

PRA Holding issued $107.6 million of 3.9% Convertible Debentures in a Private Offering transaction, net of an initial purchaser’s discount of $3.0 million, in July 2003. The Convertible Debentures are due June 30, 2023 but may be repaid or called prior to that date. PRA Holding used the net proceeds of the Convertible Debentures to pay off its existing term loan having an outstanding principal balance of $67.5 million.
In April and May 2004, PRA Holding formed two business trusts (the Trusts), as the holder of all voting securities issued by the Trusts, for the sole purpose of issuing, in private placement transactions, $45.0 million of trust preferred securities (TPS) and using the proceeds thereof, together with the equity proceeds received from ProAssurance in the initial formation of the Trusts, to purchase Subordinated Debentures issued by ProAssurance. The Subordinated Debentures and the TPS have the same maturities and other applicable terms and features. They are uncollateralized and bear a floating interest rate equal to the three-month LIBOR plus 3.85%, adjustable and payable quarterly, with a maximum rate within the first five years of 12.5%.
See Note 10 of the Notes to the consolidated financial statements of ProAssurance and its subsidiaries included herein for a detailed description of the terms of the Convertible Debentures and the Subordinated Debentures.
3. Related Party Transactions
PRA Holding received dividends of $3 million from its subsidiaries in 2005 and $28 million dividends were received in 2004. PRA Holding contributed capital of $5.9 million in 2005 to its subsidiaries. In 2004 PRA Holding contributed $18 million to its subsidiaries.
All of PRA Holding’s treasury shares are owned by its subsidiaries. In the registrant-only financial statements, stockholders’ equity has been reduced by the cost of these treasury shares and PRA Holding’s investment in subsidiaries has been reduced by the cost of the treasury shares owned by the subsidiaries.
4. Income Taxes
Under terms of PRA Holding’s tax sharing agreement with its subsidiaries, income tax provisions for individual companies are allocated on a separate company basis.

EX-10.4(J) 2 g99804exv10w4xjy.txt EX-10.4(J) RELEASE AND SEVERANCE AGREEMENT / DARRYL K. THOMAS Exhibit 10.4(J) RETENTION PLAN RELEASE AND SEVERANCE COMPENSATION AGREEMENT THIS RELEASE AND SEVERANCE COMPENSATION AGREEMENT (the "Agreement") is between ProAssurance Corporation, a Delaware corporation ("ProAssurance"), ProNational Insurance Company, a Michigan insurance company ("ProNational"), Professionals Group, Inc., a Michigan corporation ("Professionals Group") and Darryl K. Thomas, an individual (the "Executive"). ProAssurance, ProNational, and Professionals Group and their respective majority-owned subsidiaries are hereinafter collectively referred to as the "Companies." RECITALS: The Executive is currently rendering valuable services to Professionals Group and/or its wholly-owned subsidiary of ProNational. ProAssurance has acquired, or will acquire, control of Professionals Group and ProNational in a transaction (the "Consolidation") that will result in a "change of control" (the "Change of Control") under the terms and conditions of the 1996 Key Employee Retention Plan of ProNational as assumed by Professionals Group (the "Change of Control Agreement"). The Companies have offered to employ the Executive in an at will employment relationship after the Consolidation and to expand protection to the Executive in the form of severance benefits payable on termination of employment under certain circumstances after the Consolidation on the condition that the Executive releases the Companies from any past or future liability under the Change of Control Agreement. The Executive desires to continue employment with the Companies under such terms and conditions, and with the protection afforded to the Executive by this Agreement. AGREEMENT NOW, THEREFORE, These Premises Considered, and in consideration of the mutual covenants and promises in this Agreement, the sufficiency of which is hereby acknowledged, the parties agree as follows: 1. Term of Agreement. This Agreement is subject to, and conditioned upon, the closing (the "Closing") of the transactions (the "Consolidation") contemplated by the Agreement to Consolidate by and between Medical Assurance, Inc. and Professionals Group, Inc. dated June 22, 2000, as amended November 1, 2000. This Agreement is effective on the date of Closing which is scheduled to occur on June 27, 2001, and shall continue in effect for a period of two years from the date of Closing (the "Initial Term"). Thereafter, this Agreement shall automatically be extended for successive terms of one year (a "Renewal Term"), except this Agreement may be terminated after the first Renewal Term upon delivery of written notice of the termination of this Agreement by any of the Companies at least six months prior to the expiration of any Renewal Term. If the Executive's employment is terminated during the term of the Agreement, the date on which the Executive's employment terminates shall be referred to as the "Date of Termination." 2. Severance Benefits. If during the term of this Agreement the Executive leaves the employment of the Companies for Good Reason, as explained in Section 4 of this Agreement, and the Executive signs the release (the "Release") that is attached to and incorporated in this Agreement, the Executive shall receive the following benefits (the "Severance Benefits"): (a) An amount equal to either of whichever the following is applicable: (i) if the Date of Termination occurs during the Initial Term, two (2) times the Executive's annual base salary; or (ii) if the Date of Termination occurs during a 2 Renewal Term, one (1) times the Executive's annual base salary. The "annual base salary" of the Executive shall be defined as the Executive's base rate of compensation in effect as of the Date of Termination, but in no event less than the Executive's base rate of compensation in effect as of the end of the last calendar quarter preceding the Date of Termination; (b) An amount equal to either of whichever of the following is applicable: (i) if the Date of Termination occurs during the Initial Term, two (2) times the average total annual incentive award(s) or bonus(es); or (ii) if the Date of Termination occurs during a Renewal Term, one (1) times the average total annual incentive award(s) or bonus(es). The "average total annual incentive award(s) or bonus(es)" shall mean the average of the sum of (i) cash awards or bonuses earned with the Companies by the Executive, plus (ii) the value of stock awarded to the Executive by the Companies for each complete fiscal year during the last three years (whether or not deferred) or, if shorter, over the Executive's entire period of employment with the Companies. The value of stock awarded to the Executive shall be calculated based on the value of the stock as of the date the stock was awarded to the Executive as annual incentive compensation. Notwithstanding the foregoing, the Executive's actual total annual incentive awards or bonuses shall be calculated excluding the value of options to purchase stock which may have been awarded to the Executive; (c) Payment of the Executive's monthly COBRA premiums for continued health and dental insurance coverage for the shorter of the following: (i) 18 months if the Date of Termination occurs in the Initial Term; (ii) 12 months if the Date of Termination occurs in the Renewal Term; (iii) until the Executive no longer has coverage 3 under COBRA; or (iv) until the Executive becomes eligible for substantially similar coverage under a subsequent employer's group health plan; and (d) Outplacement services that are customary to Executive's position. The cash severance benefits described in subparagraphs (a) and (b) above shall be paid in equal monthly installments during the period that the covenants set forth in Section 7 shall be in effect commencing upon the Date of Termination; provided that the obligation of the Companies to pay such cash severance benefits to the Executive shall be subject to termination under the provisions of Section 7 hereof in the event the Executive should violate the covenants set forth therein; and provided further that the payment of such cash severance benefits shall be accelerated and payable in lump sum by the Companies upon a breach of this Agreement as a result of the failure of a successor (herein defined) to assume this Agreement as required in Section 10 of this Agreement. The Companies shall withhold from any amounts payable under this Agreement all federal, state, city or other income and employment taxes that shall be required. The Companies shall fund the obligation to pay cash Severance Benefits by depositing in escrow an amount equal to the sum of the amounts payable to the Executive under subparagraphs (a) and (b) hereof (the "Escrow Funds") with SouthTrust Bank (or another financial institution with total assets of more than $1,000,000,000) as escrow agent (the "Escrow Agent"). The Escrow Funds shall be the property of the Companies and shall be held, invested and distributed by Escrow Agent in accordance with the following provisions. At the time of delivery of the Escrow Funds, the Escrow Agent shall acknowledge receipt of the Escrow Funds and agree to be bound by the provisions of this Agreement in a separate written document. The Escrow Agent shall invest the Escrow Funds in a money market account for the benefit of the Companies and 4 shall distribute the earnings not more frequently than monthly. Unless and until the Escrow Agent receives notice from ProAssurance that the Executive has breached this Agreement, the Escrow Agent shall distribute the Escrow Funds to the Executive in the same number of equal monthly installments as the number of whole calendar months in the Restricted Period (as defined in Section 7 hereof). The monthly installments shall be distributed to the Executive on the first day of each calendar month in the Restricted Period together with accrued and undistributed earnings on the Escrow Funds. If the Company delivers written notice to the Escrow Agent and Executive that the cash Severance Benefits payable to Executive are subject to termination under Section 7 of this Agreement, the Escrow Agent shall distribute the balance of the Escrow Funds and accrued and undistributed earnings thereon to ProAssurance unless the Escrow Agent receives a written notice of objection from the Executive within 15 days after delivery of ProAssurance's notice. If Executive provides a timely notice of objection, the Escrow Agent shall hold the Escrow Funds until it receives a written notice of distribution from the arbitrator appointed pursuant to Section 13 hereof or a joint written notice of distribution from the Executive and ProAssurance. The failure of the Executive or the Company to deliver notice to the Escrow Agent as herein provided shall not be a waiver of any of their respective rights under this Agreement. The Executive shall be entitled to the following in addition to and not in limitation of the Severance Benefits: (i) accrued and unpaid base salary as of the Date of Termination; (ii) accrued vacation and sick leave, if any, on Date of Termination in accordance with the then current policy of the Companies with respect to terminated employees generally; and (iii) vested benefits under the Companies' employee benefit plans in which the Executive was a participant on Date of Termination, which vested benefits shall be paid or provided for in accordance with 5 the terms of said employee benefit plans. If the Executive has regular use of a vehicle provided by the Companies for business and personal use on Date of Termination, the Companies shall offer for sale to the Executive the vehicle at a purchase price equal to either of the following: (x) if owned by any of the Companies, the then current book value of the vehicle (cost less accumulated depreciation), or (y) if leased by any of the Companies, the purchase price upon the exercise of the purchase option, if any, under the lease. The Executive shall not be entitled to receive Severance Benefits if employment with the Companies is terminated by reason of death of Executive, retirement of Executive pursuant to the Company's retirement plan as then in effect, the Executive having reached the age of mandatory retirement (if such requirement then exists for bona fide executives); or Disability of Executive (herein defined); or by reason of termination of employment by the Executive without Good Reason (herein defined); or by reason of termination of employment by the Companies with Cause (herein defined). The Executive shall be under no duty or obligation to seek or accept other employment and shall not be required to mitigate the amount of the Severance Benefits provided under the Agreement by seeking employment or otherwise; provided, however, that the Executive shall be required to notify the Companies if the Executive becomes covered by a health or dental care program providing substantially similar coverage, at which time health or dental care continuation coverage provided under this Agreement shall cease. 3. Parachute Payments. Subject to Section 280G of the Internal Revenue Code of 1986, as amended ("Code"), if the board of directors of ProAssurance determines that an excise tax under Section 4999 ("Excise Tax") would be due, the Executive's Severance Benefits under this Agreement shall be limited to the amount necessary to avoid the Excise Tax only if applying 6 such a limit results in a greater net benefit to the Executive than would have resulted had the benefits not been limited and an Excise Tax paid. For purposes of making such computation: (a) Any other payments or benefits received or to be received by the Executive in connection with the Change of Control or the Executive's termination of employment (whether pursuant to the terms of this Agreement or any other plan, arrangement, or agreement with the Companies, or with any person whose actions result in the Change of Control) shall be treated as "parachute payments" within the meaning of Section 280G(b)(2) of the Code, and all "excess parachute payments" within the meaning of Section 280G(b)(1) of the Code shall be treated as subject to the Excise Tax, unless, in the opinion of tax counsel selected by ProAssurance's independent auditors, such other payments or benefits (in whole or in part) do not constitute parachute payments, or such other payments or benefits (in whole or in part) represent reasonable compensation for services actually rendered within the meaning of Section 280G(b)(4) of the Code in excess of the base amount within the meaning of Section 280G(b)(3) of the Code, or such other payments or benefits (in whole or in part) are otherwise not subject to the Excise Tax. In the event an Excise Tax is due, because of payments made under this Agreement, the Executive shall be responsible for paying said Excise Tax. (b) The amount of the Severance Benefits that will be treated as subject to the Excise Tax shall be equal to the lesser of: (i) the total amount of the Severance Benefits; or (ii) the amount of excess parachute payments within the meaning of Section 280G(b)(l) (after applying subparagraph (a) above). (c) The value of any noncash benefits or any deferred payment or benefit shall be determined by ProAssurance's independent auditors in accordance with the principles of Sections 280G(d)(3) and (4) of the Code. 7 (d) The Executive shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation in a calendar year in which the Severance Benefits are to be paid, and state and local income taxes at the highest marginal rate of taxation in the state and locality of the Executive's residence on the Date of Termination, net of the maximum reduction in federal income taxes that could be obtained from deduction of such state and local taxes. In the event the Internal Revenue Service adjusts the computation in subparagraphs (a) through (d) above, so that the Executive did not receive the greatest net benefit, the Companies shall reimburse the Executive for the amount necessary to make the payment of Severance Benefits to the Executive to the extent permitted hereunder, plus a market rate of interest as determined by the Board of Directors of ProAssurance. 4. Good Reason for Termination. In the event that the Executive's employment relationship with the Companies is terminated for any of the reasons described in this Section 4, the Executive shall be entitled to Severance Benefits, subject to and described in Section 2 of this Agreement. "Good Reason" shall constitute any of the following circumstances if they occur without the Executive's express written consent during the term of this Agreement: (a) The Executive no longer holds an executive level position with executive level responsibilities with the Companies consistent with the Executive's training and experience (Executive and Company acknowledge that the initial position and responsibilities of Executive will be as set forth in the terms of employment ("Terms of Employment") attached to, and incorporated in, this Agreement); (b) The Companies require that the Executive's primary location of employment be more than 50 miles from the location of the Executive's primary location of 8 employment on June 27, 2001; provided, however, that it is agreed that the relocation of Executive's principal office to Birmingham, Alabama will not violate this subparagraph and that after the relocation to Birmingham, the fifty (50) mile radius will apply with respect to the Birmingham location; (c) The failure of the Companies to provide the Executive, at a level in 2001 as set forth in the Terms of Employment and thereafter at a level commensurate with the Executive's position, the incentive compensation opportunities and employee benefits that are provided to other executives of comparable rank with the Companies; (d) A breach by the Companies of any provision of this Agreement, including without limitation, the failure of a successor to assume this Agreement as required in Section 10 hereof; (e) The termination of the Executive's employment by the Companies for a reason other than: (i) death; (ii) retirement pursuant to the Companies' retirement plan as then in effect; (iii) Disability as explained in Section 5 of this Agreement; (iv) the Executive has reached the age of mandatory retirement (if such requirement then exists for bona fide executives); (v) for Cause, as explained in Section 7 of this Agreement; (f) A reduction by the Companies in the Executive's base salary as set forth in the Terms of Employment; or (g) The termination or non-renewal of this Agreement by the Companies. The Executive must provide the Companies with written notice no later than 45 calendar days after the Executive knows or should have known that Good Reason has occurred. Following the Executive's Notice, the Companies shall have 45 calendar days to rectify the 9 circumstances causing the Good Reason. If the Company fails to rectify the event(s) causing the Good Reason within the 45 day period after the Executive's Notice, or if any of the Companies delivers to the Executive written notice stating that the circumstances cannot or shall not be rectified, the Executive shall be entitled to assert Good Reason and terminate employment on or before 90 days after the delivery of the Executive's Notice. Should Executive fail to provide the required Notice in a timely manner, Good Reason shall not be deemed to have occurred as a result of that event. The Initial Term or a Renewal Term shall not be deemed to have expired during the Notice period, however, as long as the Executive has provided Notice within the Term. 5. Disability. For purposes of this Agreement, Disability means a serious injury or illness that requires the Executive to be under the regular care of a licensed medical physician and renders the Executive incapable of performing the essential functions of the Executive's position for 12 months as determined by the Board of Directors of the Companies in good faith and upon receipt of and in reliance on competent medical advice from one or more individuals selected by the Board of Directors, who are qualified to give professional medical advice. 6. Cause. If the Executive's employment relationship with the Companies is terminated for Cause by the Companies, as described below in this Section, the Executive shall not be eligible for Severance Benefits and all rights of the Executive and obligations of the Companies under this Agreement shall expire. Cause means: (a) The Executive has been convicted in a federal or state court of a crime classified as a felony; (b) Action or inaction by the Executive (i) that constitutes embezzlement, theft, misappropriation or conversion of assets of the Companies which alone or together with related 10 actions or inactions involve assets of more than a de minimis amount, or that constitutes fraud, gross malfeasance of duty, or conduct grossly inappropriate to Executive's office; and (ii) such action or inaction has adversely affected or is likely to adversely affect the business of the Companies or has resulted or is intended to result in direct or indirect gain or personal enrichment of the Executive to the detriment of the Companies; (c) The Executive has been grossly inattentive to, or in a grossly negligent manner failed to competently perform, Executive's job duties and the failure was not cured within 45 days after written notice from the Companies. Any termination of the Executive's employment by the Companies for Cause shall be communicated by a notice of termination (the "Notice of Termination") to the Executive. The Notice of Termination shall be a written notice indicating the specific termination provision of this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive's employment under this provision. 7. Non-Competition. (a) In the event the Date of Termination occurs during the Initial Term, the Executive (i) will be bound by and subject to any covenant not to compete or noncompetition agreement with the Companies (or any of them) to which the Executive was subject as of the Date of Termination (other than the noncompetition agreement set forth in Section 7(b) hereof), or (ii) in the alternative if the Executive is not subject to a covenant not to compete or noncompetition agreement with the Companies (or any of them) as of the Date of Termination (other than a covenant not to compete or noncompetition agreement contained in an employee handbook or otherwise applicable to employees generally) the Executive will be bound by and subject to the noncompetition agreement set forth in subparagraph 7(b) of this Agreement. Upon 11 the expiration of the Initial Term, any and all covenants not to compete or noncompetition agreements between the Executive and the Companies (or any of them) then in effect shall be superseded by the noncompetition agreement set forth in Section 7(b) hereof and the Executive and the Companies shall not be bound by the provisions of any covenant not to compete or noncompetition agreement other than the provisions of Section 7(b) hereof unless specifically agreed to in a written document executed by the Executive and the Companies (or any of them) after the Closing. (b) In the event that either (i) the Date of Termination occurs during the Initial Term and the provisions of Section 7(a)(ii) hereof are binding on the Executive, or (ii) the Date of Termination occurs during a Renewal Term, the Executive will not during the Restricted Period (herein defined): (i) become employed by a competitor company at any location and directly solicit or sell medical professional liability insurance to any person or entity that was insured by any of the Companies within one year prior to the Date or Termination, or directly provide services related to medical professional liability insurance to any such person or entity; or (ii) receive or earn compensation of any type directly arising out of the purchase of medical professional liability insurance by any person or entity that was insured by the Companies at any time within one year prior to the Date of Termination; or (iii) solicit or induce any other employees of the Companies to leave such employment or accept employment with any other person or entity, or solicit or 12 induce any insurance agent of the Companies to offer, sell or market medical professional liability insurance for a competitor company in the primary market of the Companies. "Competitor company" means an insurance company, insurance agency, business, for profit or not for profit organization (other than the Companies) that provides, or offers to provide medical professional liability insurance to health care providers. "Health care providers" means physicians, dentists, podiatrists, physician assistants, nurse practitioners, other individual health care providers and hospital and other institutional health care providers. "Medical professional liability insurance" means medical malpractice insurance and reinsurance, and equivalent self-insured services such as administration of self-insured trusts, claims management services and risk management services for health care providers. "Medical professional liability insurance" does not include services provided as an employee of a health care provider if such services are rendered solely for the purpose of servicing medical professional liability risk of the employer or that of its employees. "Primary market area" means any state in which the Companies derived more than $5 million in direct written premiums from the sale of medical professional liability insurance to health care providers in the most recent complete fiscal year prior to the Date of Termination. "Restricted Period" means as applicable either (i) if the Date of Termination occurs within the Initial Term, a period of 24 months from such Date 13 of Termination; or (ii) if the Date of Termination occurs within a Renewal Term, a period of 12 months from such Date of Termination. "Employed" includes activities as an owner, proprietor, employee, agent, solicitor, partner, member, manager, principal, shareholder (owning more than 1% of the outstanding stock), consultant, officer, director or independent contractor. "Companies" means any company that is a subsidiary of ProAssurance, now or in the future, and any other company that has succeeded to the business of any of the Companies. If the Executive is deemed to have materially breached the non-competition covenants set forth in Section 7 of this Agreement, the Companies may, in addition to seeking an injunction or any other remedy they may have, withhold or cancel any remaining payments or benefits due to the Executive pursuant to Section 2 of this Agreement. The Companies shall give prior or contemporaneous written notice of such withholding or cancellation of payments in accordance with Section 2 hereof. If the Executive violates any of these restrictions, the Companies shall be further entitled to an immediate preliminary and permanent injunctive relief, without bond, in addition to any other remedy which may be available to the Companies. Both parties agree that the restrictions in this Agreement are fair and reasonable in all respects, including the geographic and temporal restrictions, and that the benefits described in this Agreement, to the extent any separate or special consideration is necessary, are fully sufficient consideration for the Executive's obligations under this Agreement. 8. Confidentiality. Executive will remain obligated under any confidentiality or nondisclosure agreement with the Companies (or any of them) that is currently in effect or to 14 which the Executive may in the future be bound. In the event that the Executive is at any time not the subject of a separate confidentiality or nondisclosure agreement with the Companies (or any of them), Executive expressly agrees that Executive shall not use for the Executive's personal benefit, or disclose, communicate or divulge to, or use for the direct or indirect benefit of any person, firm, association or company any confidential or competitive material or information of the Companies or their subsidiaries, including without limitation, any information regarding insureds or other customers, actual or prospective, and the contents of their files; marketing, underwriting or financial plans or analyses which is not a matter of public record; claims practices or analyses which are not matters of public record; pending or past litigation in which the Companies have been involved and which is not a matter of public record; and all other strategic plans, analyses of operations, computer programs, personnel information and other proprietary information with respect to the Companies which are not matters of public record. Executive shall return to the Companies promptly, and in no event later than the Date of Termination, all items, documents, lists and other materials belonging to the Companies or their subsidiaries, including but not limited to, credit, debit or service cards, all documents, computer tapes, or other business records or information, keys and all other items in the Executive's possession or control. 9. Release of Change of Control Agreement. In consideration of the continued employment of the Executive by the Companies after the Change of Control and the obligation of the Companies to pay the Executive Severance Benefits as herein provided, the Executive hereby waives, releases and forever discharges the Companies and each of their direct or indirect parents, subsidiaries, affiliates and related entities, and all present or former employees, officers, agents, directors or representatives of any of them, from any and all claims, charges, suits, causes 15 of action, demands, expenses and compensation whatsoever, known or unknown, direct or indirect, on account of or growing out of the Executive's Change of Control Agreement, including, without limitation, the payment of severance benefits as provided thereunder. Executive hereby further agrees that he will not institute any suit or action at law, in equity or otherwise against the Companies or any of their direct or indirect parents, subsidiaries, affiliates and related entities, or the present or former employees, officers, agents, directors, or representatives of any of them and their respective successors and assigns, nor will the Executive ever institute, prosecute, or in any way aid in the institutional prosecution of any claim, demand, action or cause of action for damages, costs, expenses, penalties, fines, compensation or equitable relief, for or on account of any damage, loss or injury to either person or property or both, whether developed or undeveloped, resulting or to result, known or unknown, which Executive ever had, now has, or which Executive or his successors and assigns may in the future have against any of said persons in connection with the Change of Control Agreement of the Executive. The Executive acknowledges and agrees that Executive has been advised in writing by this Agreement, and otherwise, to CONSULT WITH AN ATTORNEY before Executive enters into this Agreement. The Executive agrees that the Executive received and read a copy of this Agreement prior to executing the same. 10. Successors of ProAssurance. ProAssurance will require any successor (herein defined) to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Companies would be required to perform this Agreement if no such succession had taken place. Failure of ProAssurance to obtain such agreement prior to the effectiveness of any such succession shall be a breach of this Agreement and shall entitle the 16 Executive to terminate employment for Good Reason and receive Severance Benefits as provided in Section 2 hereof. Reference to the Companies in this Agreement shall include any successor which assumes and agrees to perform this Agreement by operation of law or otherwise. The term "successor" means any Person, as defined by Section 3(a)(9) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") other than a Person in control of the Companies immediately after completion of the Change of Control, that either (i) becomes the Beneficial Owner, as defined by Rule 13d-3 of the General Rules and Regulations under the Exchange Act, directly or indirectly, of the securities of ProAssurance representing more than 50.1% of the combined voting power of the then outstanding securities of ProAssurance; (ii) purchases or otherwise acquires substantially all of the assets of the Companies such that the Companies cease to function on a going forward basis as an insurance holding company system that provides medical professional liability insurance; or (iii) survives a merger, consolidation or reorganization that results in less than 50.1% of the combined voting power of ProAssurance or such surviving entity being owned by stockholders of ProAssurance immediately preceding such merger, consolidation or reorganization. 11. Notice. For purposes of this Agreement, notices and all other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given when delivered by hand or commercial courier or mailed by certified or registered mail, return receipt requested, postage prepaid, addressed to the respective addresses as set forth below or to such other address as one party may have furnished to the other in writing in accordance herewith. 17 Notice to the Executive: Darryl K.

Box 590009 Birmingham, Alabama 35259-0009 Street Address: 100 Brookwood Place Birmingham, Alabama 35209 Attention: Chairman of the Board 12. Claims Procedure. (a) The administrator for purposes of this Agreement shall be ProAssurance ("Administrator"), whose address is 100 Brookwood Place, Birmingham, Alabama 35209; Telephone: (205) 877-4400. The "Named Fiduciary" as defined in Section 402(a)(2) or ERISA, also shall be ProAssurance. ProAssurance shall have the right to designate one or more employees of the Companies as the Administrator and the Named Fiduciary at any time, and to change the address and telephone number of the same. ProAssurance shall give the Executive written notice of any change in the Administrator and Named Fiduciary, or in the address or telephone number of the same. (b) The Administrator shall make all determinations as to the right of any person to receive benefits under the Agreement. Any denial by the Administrator of a claim for benefits by the Executive ("the claimant") shall be stated in writing by the Administrator and delivered or mailed to the claimant within ten (10) days after receipt of the claim, unless special circumstances require an extension of time for processing the claim. If such an extension is 18 required, written notice of the extension shall be furnished to the claimant prior to the termination of the initial 10-day period. In no event shall such extension exceed a period of ten (10) days from the end of the initial period. Any notice of denial shall set forth the specific reasons for the denial, specific reference to pertinent provisions of this Agreement upon which the denial is based, a description of any additional material or information necessary for the claimant to perfect the claim, with an explanation of why such material or information is necessary, and any explanation of claim review procedures, written to the best of the Administrator's ability in a manner that may be understood without legal or actuarial counsel. (c) A claimant whose claim for benefits has been wholly or partially denied by the Administrator may request, within ten (10) days following the receipt of such denial, in a writing addressed to the Administrator, a review of such denial. The claimant shall be entitled to submit such issues or comments in writing or otherwise, as the claimant shall consider relevant to a determination of the claim, and the claimant may include a request for a hearing in person before the Administrator. Prior to submitting the request, the claimant shall be entitled to review such documents as the Administrator shall agree are pertinent to the claim. The claimant may, at all stages of review, be represented by counsel, legal or otherwise, of the claimant's choice. All requests for review shall be promptly resolved. The Administrator's decision with respect to any such review shall be set forth in writing and shall be mailed to the claimant not later than ten (10) days following receipt by the Administrator of the claimant's request unless special circumstances, such as the need to hold a hearing, require an extension of time for processing, in which case the Administrator's decision shall be so mailed not later than twenty (20) days after receipt of such request. 19 13. Arbitration. The parties to this Agreement agree that final and binding arbitration shall be the sole recourse to settle any claim or controversy arising out of or relating to a breach or the interpretation of this Agreement, except as either party may be seeking injunctive relief. Either party may file for arbitration. A claimant seeking relief on a claim for benefits, however, must first follow the procedure in Section 12 hereof and may file for arbitration within sixty (60) days following claimant's receipt of the Administrator's written decision on review under Section 12(c) hereof, or if the Administrator fails to provide any written decision under Section 12 hereof, within 60 days of the date on which such written decision was required to be delivered to the claimant as therein provided. The arbitration shall be held at a mutually agreeable location, and shall be subject to and in accordance with the arbitration rules then in effect of the American Arbitration Association; provided that if the location cannot be agreed upon the arbitration shall be held in either Atlanta, Georgia, or Chicago, Illinois, whichever location is closer to the principal office where the Executive was employed on the Date of Termination. The arbitrator may award any and all remedies allowable by the cause of action subject to the arbitration, but the arbitrator's sole authority shall be to interpret and apply the provisions of this Agreement. In reaching its decision the arbitrator shall have no authority to change or modify any provision of this Agreement or other written agreement between the parties. The arbitrator shall have the power to compel the attendance of witnesses at the hearing. Any court having jurisdiction may enter a judgment based upon such arbitration. All decisions of the arbitrator shall be final and binding on the parties without appeal to any court. Upon execution of this Agreement, the Executive shall be deemed to have waived any right to commence litigation proceedings regarding this Agreement outside of arbitration or injunctive relief without the express consent of ProAssurance. The Companies shall pay all arbitration fees and the 20 arbitrator's compensation. If the Executive prevails in the arbitration proceeding, the Companies shall reimburse to the Executive the reasonable fees and expenses of Executive's personal counsel for his or her professional services rendered to the Executive in connection with the enforcement of this Agreement. 14. Miscellaneous. (a) Except insofar as this provision may be contrary to applicable law, no sale, transfer, alienation, assignment, pledge, collateralization or attachment of any benefits under this Agreement shall be valid or recognized by the Companies. (b) This Agreement is an unfunded deferred compensation arrangement for a member of a select group of the Companies' management and any exemptions under ERISA, as applicable to such arrangement, shall be applicable to this Agreement. Nothing in this Agreement shall require or be deemed to require the Companies or any of them to segregate, earmark or otherwise set aside any funds or other assets to provide for any payments made or required to be made hereunder. (c) Nothing in this Agreement shall be deemed to create an employment agreement between the Executive and the Companies or any of them providing for Executive's employment for any fixed duration, nor shall it be deemed to modify or undercut the Executive's at will employment status with the Companies. (d) Neither the provisions of this Agreement nor the severance benefits provided hereunder shall reduce any amounts otherwise payable, or in any way diminish the Executive's rights as an employee of the Companies, whether existing now or hereafter, under 21 any benefit, incentive, retirement, stock option, stock bonus or stock purchase plan, or any employment agreement or other plan or arrangement. (e) This Agreement sets forth the entire agreement between the parties with respect to the matters set forth herein. This Agreement may not be modified or amended except by written agreement intended as such and signed by all parties. (f) This Agreement shall benefit and be binding upon the parties and their respective directors, officers, employees, representatives, agents, heirs, successors, assigns, devisees, and legal or personal representatives. (g) The Companies, from time to time, shall provide government agencies with such reports concerning this Agreement as may be required by law, and shall provide Executive with such disclosure concerning this Agreement as may be required by law or as the Companies may deem appropriate. (h) Executive and the Companies respectively acknowledge that each of them has read and understand this Agreement, that they have each had adequate time to consider this Agreement and discuss it with each of their attorneys and advisors, that each of them understands the consequences of entering into this Agreement, that each of them is knowingly and voluntarily entering into this Agreement, and that they are each competent to enter into this Agreement. (i) If any provision of this Agreement is determined to be unenforceable, at the discretion of ProAssurance the remainder of this Agreement shall not be affected but each remaining provision shall continue to be valid and effective and shall be modified so that it is enforceable to the fullest extent permitted by law. Moreover, in the event this Agreement is 22 determined to be unenforceable against any of the Companies, it shall continue to be valid and enforceable against the other Companies. (j) This Agreement will be interpreted as a whole according to its fair terms. It will not be construed strictly for or against either party. (k) Except to the extent that federal law controls, this Agreement is to be construed according to Michigan law. IN WITNESS WHEREOF, the parties have duly executed this Agreement as of this 27TH day of JUNE, 2001. EXECUTIVE: /s/ Darryl K. Thomas ---------------------------------------- Darryl K.
