Additionally, the Board declared a special dividend of $2.50 per share and a quarterly dividend of $0.25, both paid on December 27, 2012, on a post-split basis.
We entered into a revolving credit agreement in April 2011 and updated the agreement in September 2012. The agreement, which expires in April 2016, allows us to borrow up to $150 million for general corporate purposes, including, but not limited to, short-term working capital, share repurchases as authorized by the Board, and support for other activities we enter intoassist them in the normal courseuse of business. In December 2012 we elected to partially fund our acquisition of Medmarc by borrowing $125 million from our existing credit facility on a fully secured basis as this allowed us to continue to hold rather than liquidate certain higher yielding securities. At December 31, 2012, $25 million of the credit facility remains available for use. See Note 10 of the Notes to Consolidated Financial Statements included herein for additional information regarding the revolving credit agreement.risk reduction tools and techniques.
During 2012, we used $57.7 million of available funds to repay long-term debt and terminate a related interest rate swap. We recognized a loss on the debt repayment of $2.2 million.
On November 30, 2010 we acquired 100% of the outstanding shares of APS, a provider of medical professional liability (MPL) insurance for physicians largely in the state of Texas, in a transaction valued at $237 million, including cash paid of $233 million and liabilities assumed of $4 million. See Note 2 of the Notes to Consolidated Financial Statements included herein for additional information regarding the acquisition of APS.
In November 2010 the Board authorized $200 million to be used for the repurchase of our common stock or debt securities, which was in addition to previous authorizations of $100 million in September 2009, $100 million in August 2008

Organization and Segment Information
We operate through multiple insurance organizations with four areas of focus: professional liability insurance, medical technology and life sciences products liability insurance, and beginning January 1, 2014, workers' compensation insurance and international property and casualty insurance and reinsurance.

In 2014 we expect to report our results in four segments: specialty property and casualty, workers' compensation, Lloyd's syndicate and corporate. Our corporate segment includes our investing operations managed at the corporate level, non-premium revenues generated outside of our insurance entities, and corporate expenses.

For our legal professional liability product, we target smaller law practices. Our Medmarc subsidiary, acquired on January 1, 2013, offers products liability insurance for medical technology and life sciences companies. While most of our business is written in the standard market, we also offer professional and products liability insurance on an excess and surplus lines basis. We are licensed to do business in every state. For the years ended December 31, 2013, 2012 and 2011 physician coverages represented 73%, 78% and 80%, respectively, of the consolidated gross premiums written.
We utilize independent agencies and brokers as well as an internal sales force to write our healthcare professional liability (HCPL) business.

We maintain regional underwriting and claims processing centers which permit us to consistently provide a high level of customer service to both small and large accounts.
Underwriting
Our underwriting process is driven by individual risk selection. Our underwriting decisions are focused on achieving pricing adequacy. ForWe maintain internal claims personnel that investigate and monitor the processing of our professional liability business, we assess the qualityclaims, and pricing of the risk, emphasizing loss history, areas of practice and location in making our underwriting decision. For our products liability business, we consider the type of risk, the amount of coverage being sought, the expertise and experience of the applicant, the location of the risk, and the expected volume of product sales in making our underwriting decision. 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.
Our professional liability underwriting concentrates on knowledge of local market conditions and legal environments through market-focused underwriting offices located throughout our business footprint. Our underwriters work closely with our claims departments, consulting with staff about claims histories and patterns of practice in a particular locale as well as monitoring claims activity.

For our MPL business, underwriters are assisted by our medical advisory committees that operate in our key markets. These committees are comprised of physicians, representatives of hospitals and healthcare entities, and other medical professionals, and help us maintain close ties to the medical communities in these markets, provide information on the practice of medicineengage experienced, independent litigation attorneys in each market and provide guidance on critical underwriting issues.
Claims Management
We have professional liabilityvenue to assist with the claims offices strategically located throughout our business footprint so that we can provide specialized and timely attention to claims. If desired by the insured, we offer a strong defense of claims thatprocess as we believe are non-meritorious or claimsthis practice aids us in providing defense that we believe cannot be settled reasonably by good faith negotiations.

We strongly defend these claims as well, with a negotiated settlement being the most frequent means of resolution.
Our internal claims personnel promptly and thoroughly investigate the circumstances surrounding each reported claim against an insured. As this investigation progresses, our claims department develops an estimate of the case reserves for each claim. Thereafter, we monitor development of new information about the claim and adjust the case reserve as loss cost estimates are revised.
Through our investigation, and in consultation with the insured and appropriate experts, we evaluate the merit of theeach claim and determine the appropriate strategy for resolution of the claim, either seeking a reasonable good faith settlement appropriate for the circumstance of the claim or aggressively defending the claim. Our claims personnel carefully manage each case, and obtain medical, legal and/or other expert professionals as needed to assist in the analysis and defense of the claim. As part of the evaluation and preparation process for medicalhealthcare professional liability claims, we meet regularly with medical advisory committees in our key markets to examine claims, attempt to identify potentially troubling practice patterns and make recommendations to our staff.

Medical Technology and Life Sciences Insurance
Our Medical Technology and Life Sciences business, acquired January 1, 2013 through the acquisition of Medmarc, offers products liability insurance for medical technology and life sciences companies that manufacture or distribute products that are almost all regulated by the United States Food and Drug Administration. Products insured include imaging and non-invasive diagnostic medical devices, orthopedic implants, pharmaceuticals, clinical lab instruments, medical instruments, dental products, and animal pharmaceuticals and medical devices. We also provide coverage for clinical trials and contract manufacturers.
In underwriting our products liability business, we consider the type of risk, the amount of coverage being sought, the expertise and experience of the applicant, and the expected volume of product sales in making our underwriting decision. Close to 100% of our products liability business is written through independent brokers with our top ten producers generating approximately $16 million of our 2013 gross premiums written. We do not appoint agents for our products liability business.
Our products liability claims are centrally processed in Chantilly, Virginia. We strongly defend these claims, with a negotiated settlement being the most frequent means of resolution.

conditions, breadth and flexibility of coverage, method of sale, financial stability, ratings assigned by rating agencies and regulatory conditions. Our competitors range from large national insurers whose financial strength and resources may be greater than ours to smaller insurance entities that is aggressive, effectiveconcentrate on a single state and cost-efficient.
We believe our local approach to claims contributes to lower overall loss costs and results in customer loyalty, particularly for our physician insureds. Our claims personnel are experienced claims professionals who possess specializedas a result have an extensive knowledge of the local medicalmarkets.
We are widely recognized in our HCPL markets for our heritage as a policyholder founded company with a long-term focus on the industry and for strong and effective claims management. Historically, we have principally insured physicians in a solo or small group practice, but in recent years we have increased our focus on offering unique, joint or cooperative insurance programs that are attractive to hospitals or other large groups. Often, these large groups and hospitals choose to manage their HCPL risks through alternative insurance mechanisms such as risk retention groups or self-insurance entities, and we offer insurance programs designed to compete with these mechanisms. In recent years there has been a substantial increase in the number of physicians employed full time by hospitals or large group practices, which industry-wide has reduced the number of physicians insured on an individual or small-group basis. Additionally, many believe that healthcare services in the United States will increasingly be provided by professionals other than physicians and outside of hospital settings. We have addressed these issues by refining our existing hospital/physician insurance programs, developing new insurance mechanisms to meet the needs of hospitals and large practice groups, expanding our coverage of healthcare providers other than physician or hospitals, and by enhancing our customer service capabilities, particularly with regard to larger accounts. We believe that our size, reputation for effective claims management, unique customer service focus, multi-state presence, and experience with a broad spectrum of healthcare professionals will provide us with competitive advantages as the HCPL marketplace changes.
We recognize the importance of providing our products at competitive rates. We base our rates on current loss projections, and targeted new business and renewal retention programs where we consider appropriate based on the risks assumed.
Competition in the legal environmentsprofessional liability market is also varied, with coverage offered by both large national property and casualty providers and smaller specialty providers, including mutual companies affiliated with one or more state legal professional association.
Competition in the products liability market is among national property and casualty insurers, some of which are ablesignificantly larger than ProAssurance.
Workers' Compensation Segment
Effective January 1, 2014 ProAssurance acquired Eastern, which offers workers' compensation products in the Mid-Atlantic (primarily in Pennsylvania), Southeast, and Midwest regions of the continental United States. The operating results of Eastern will be included in our consolidated results beginning January 1, 2014.
Our workers' compensation business consists of two major business activities:
Workers' compensation insurance coverages provided to effectively assist our independent attorneysemployers, generally those with defending our claims.1,000 employees or less. Types of policies offered include guaranteed cost policies, policyholder dividend policies, retrospectively-rated policies, deductible policies, and alternative market products.
Investments
The majorityAlternative market workers’ compensation solutions provided to individual companies, groups and associations (referred to hereafter as “cell participants”) whereby policies written are 100% reinsured by related segregated portfolio cells of our subsidiary domiciled in the Cayman Islands. The pool of assets and associated liabilities of each segregated portfolio cell are heldsolely for the benefit of the cell participants, and the pool of assets of one segregated portfolio cell are statutorily protected from the creditors of the others. The underwriting results and investment income of the segregated portfolio cells are shared with the cell participants in accordance with the terms of the cell agreements. We principally receive fee revenue from the cells, and for cells in which we are a cell participant, a percentage of the profit or loss of the cell.
Both groups of workers' compensation products are distributed through a group of appointed independent agents.
We utilize an individual account underwriting strategy for our workers' compensation business that is focused on selecting quality accounts. The goal of our workers’ compensation underwriters is to select a diverse book of business with respect to risk classification, hazard level and geographic location. We target accounts with strong return to work and safety programs in low to middle hazard levels such as clerical office, light manufacturing, healthcare, auto dealers and service industries and maintain a strong risk management unit in order to better serve our customers' needs.
We actively seek to reduce our workers' compensation loss costs by placing an emphasis on early intervention and aggressive disability management, utilizing in-house and third-party specialists for case management, including medical cost management. Strategic vendor relationships have been established to reduce claim costs associated with legal representation and medical costs such as physician and hospital charges, physical therapy services and prescription drugs.

Competition
As with our professional and product liability business, there is substantial competition for our workers' compensation business. Workers’ compensation insurance companies,is subject to significant price competition. In addition to price, competition in the workers’ compensation insurance line of business is based on quality of the products, quality and delivery of service, financial strength, ratings, distribution systems and technical expertise. Competitors include both regional specialized providers and large national insurance entities offering a full spectrum of business liability products.
Lloyd's Syndicate Segment
Late in 2013, we completed the process of becoming a corporate member of Lloyd's of London, an internationally recognized specialist insurance market. We are the majority (58%) capital provider to Syndicate 1729, which began writing business as of January 1, 2014. The remaining capital for Syndicate 1729 is provided by unrelated third parties, including private names and other corporate members. We have committed £47.3 million ($78.3 million*) of capital for the first year of Syndicate 1729 operations and have a total capital commitment through 2019 of up to $200 million. Syndicate 1729 will cover a range of property and casualty insurance and reinsurance lines, and has a maximum underwriting capacity of £75 million ($124.2 million*) for the 2014 underwriting year, of which £43.2 million ($71.5 million*) is our allocated underwriting capacity as a corporate member.
Syndicate 1729 faces significant competition from other Lloyd's syndicates, U.S. insurers operating internationally, and international and domestic insurers offering similar coverages. Competition is based on price, types and quality of product offered, and service quality. Syndicate 1729 is led by an experienced Lloyd's insurance and reinsurance underwriter, which we believe provides a competitive advantage.
*$ amounts estimated using the GBP exchange rate as of December 31, 2013.
Corporate Segment
We manage our investments at the corporate level and we apply a consistent management strategy to the entire portfolio. Accordingly, we report our investment results and net realized investment gains and losses within our corporate segment. Our corporate segment also includes certain revenues and expenses which management does not consider in evaluating the financial results of our other operating segments, interest expense and taxes.
Our overall investment strategy is to focus on maximizing current income from our investment portfolio while maintaining safety, liquidity, duration targets and portfolio diversification. The portfolio is generally managed by professional third party asset managers whose results we monitor and evaluate. The asset managers typically have the authority to make investment decisions within the asset classes they are responsible for managing, subject to our investment policy and oversight, including a requirement that securities in a loss position cannot be sold without specific authorization from us. See Note 4 of the Notes to Consolidated Financial Statements for more information on our investments.
Rating Agencies
Our claims paying ability is regularly evaluated and rated by three major rating agencies, A. M. Best, Fitch and Moody’s. In developing their claims paying ratings, these agencies make an independent evaluation of an insurer’s ability to meet its obligations to policyholders.

While financial strength ratings may be of greater interest to investors than our claims paying ratings, these ratings are not evaluations of our equity securities nor a recommendation to buy, hold or sell our equity securities.
Competition
Within our primary MPL line of business, we compete in a fragmented market comprised of more than one hundred providers, according to 2011 industry data, with the top five writers having a combined market share of approximately 32%. We are the fourth largest MPL writer in the United States. Competitive distinctions vary from state-to-state and within areas of healthcare delivery (e.g., individual physicians vs. hospitals and facilities) and include pricing, size, name recognition, service quality, market commitment, market conditions, breadth and flexibility of coverage, method of sale, financial stability, ratings assigned by rating agencies and regulatory conditions. Our competitors range from large national insurers whose financial strength and resources may be greater than ours to smaller insurance entities that concentrate on a single state and as a result have an extensive knowledge of the local markets.
Our financial stability, local market presence and knowledge, leading position in a number of markets, service quality, experience insuring hospitals and facilities as well as individual providers, size, and geographic scope provide us with competitive advantages. We are widely recognized in our markets for our heritage as a policyholder founded company with a long-term focus on the professional liability insurance industry as well as our demonstrated commitment to the defense of non-meritorious claims and the prompt, reasonable settlement of those claims that involve a breach of the applicable standard of professional care by our insured, and that have caused damages that are covered by our insurance policy.
Historically, we have principally insured solo or small group practitioners, but in recent years we have increased our focus on offering unique, joint or cooperative insurance programs that are attractive to hospitals or other large groups. Often, these large groups and hospitals choose to manage their MPL risks through alternative insurance mechanisms such as risk retention groups or self insurance entities, and we offer insurance programs designed to compete with these mechanisms. In recent years there has been a substantial increase in the number of physicians employed full time by hospitals or large group practices, which has required us to refine our existing hospital/physician insurance programs and develop new insurance mechanisms to serve this emerging market.
Our regional claims and underwriting offices also provide competitive advantages. We utilize our local market knowledge to rigorously underwrite each application for coverage to ensure that we understand and develop adequate prices for the risks we accept. Our local market knowledge also allows us to effectively evaluate claims because we have a detailed understanding of local medical and legal climates. Our locally-based claims and underwriting professionals allow us to cultivate and maintain active relationships with our customers so that we can quickly respond to their needs.
Additionally, we differentiate ProAssurance from our competitors through our “Treated Fairly” corporate culture. “Treated Fairly” is our public pledge that all of our actions will deliver fair treatment, informed by the core values that guide our organization: integrity, respect, doctor involvement in our healthcare insurance activities, collaboration, communication, and enthusiasm.
Economic pressures on our insureds continue to increase and we recognize the importance of providing our products at competitive rates. In general, loss cost trends have mitigated in recent years resulting in corresponding rate reductions. In

addition to reflecting current loss trends in our filed rates, we have responded by offering targeted new business and renewal retention programs in selected markets. These steps improve policyholder retention but decrease our average premiums. We do not aggressively compete on price alone, and we have not compromised our commitment to disciplined underwriting.
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 active insurance subsidiaries and other states in which our insurance subsidiaries do business. Our primary active insurance subsidiaries are domiciled in the United States. Our states of domicile include Alabama, Illinois, Michigan, NevadaPennsylvania, and Vermont. We have reinsurance operations based in the Cayman Islands and, through our Lloyd's Syndicate segment, we have insurance operations based in the United Kingdom.
United States
Our insurance subsidiaries are required to file detailed annual statements with the state insurance regulators in each of the states in which they do business. The laws of the various states establish agencies with broad authority to regulate, among other

11


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. Such regulations may hamper our ability to meet operating or profitability goals, including preventing us from establishing premium rates for some classes of insureds that adequately reflects the level of risk assumed for those classes. 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 companies are also subject to state and federal legislative and regulatory measures and judicial decisions. These could include new or updated definitions of risk exposure and limitations on business practices.
Insurance Regulation Concerning Change or Acquisition of Control
The insurance regulatory codes in each of the domiciliary states of our operating subsidiaries contain 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. Because of these regulatory requirements, any party seeking to acquire control of ProAssurance or any other domestic insurance company, whether directly or indirectly, would usually be required to obtain such approval.approvals.
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 quarterly and 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 Principles (SAP). Insurance regulators periodically examine each insurer’s adherence to SAP, financial condition, and compliance with insurance department rules and regulations.
In late 2010, the National Association of Insurance Commissioners (the NAIC) adopted the Model Insurance and Holding Company System Regulatory Act and Regulation (“Model Law”). The Model Law, as compared to previous NAIC guidance, increases regulatory oversight of and reporting by insurance holding companies, including reporting related to non-insurance entities, and requires reporting of risks affecting the holding company group. Additionally, in 2012 the NAIC adopted the Risk Management and Own Risk and Solvency Assessment Model Act (ORSA), which requires insurers to maintain a framework for identifying, assessing, monitoring, managing and reporting on the “material and relevant risks” associated with the insurer's (or insurance group's) current and future business plans. ORSA will also require insurers to file an internal assessment of solvency with insurance regulators annually beginning in 2015. Although no specific capital adequacy standard is currently articulated in ORSA, it is possible that such standard will be developed over time. The Model Law and ORSA will be binding only if adopted by state legislatures and/or state insurance regulatory authorities and actual regulations adopted by any state may differ from the Model Law. None of the states in which we are domiciled have adopted the Model Law.Law or ORSA.

Regulation of Dividends and Other Payments from Our Operating Subsidiaries
Our operating subsidiaries are subject to various state statutory and regulatory restrictions that limit the amount of dividends or distributions an insurance company may pay to its shareholders, including our insurance holding company, without prior regulatory approval. Generally, dividends may be paid only out of unassigned 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.
State insurance holding company regulations generally require domestic insurers to obtain prior approval of extraordinary dividends. Insurance holding company regulations that govern our principal operating subsidiaries deem a dividend as extraordinary if the combined dividends and distributions to the parent holding company in any twelve-month period exceed prescribed thresholds. Such thresholds are more thanstatutorily prescribed by the greaterstate of domicile and currently are based on either the insurer’s net

income (for Vermont and Michigan, net income not including realized capital gains) for the prior fiscal year (reduced by realized capital gains in certain domiciliary states) or 10%a percentage of itsunassigned surplus at the end of the prior fiscal year.year, depending upon the wording of the statute.
If insurance regulators determine that payment of a dividend or any other payments within a holding company group, (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.
Risk-Based Capital
In order to enhance the regulation of insurer solvency, the NAIC specifies risk-based capital requirements for property and casualty insurance companies. At December 31, 20122013, all of ProAssurance’s insurance subsidiaries substantially exceeded the minimum required risk-based capital levels.
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 of investments. We monitor the practices used by our operating subsidiaries for compliance with applicable state investment regulations and take corrective measures when deficiencies are identified.
Guaranty Funds
Admitted insurance companies are required to be members of guaranty associations which administer state guaranty funds. To fund the payment of claims (up to prescribed limits) against insurance companies that become insolvent, these associations levy assessments 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, although state regulations may permit larger assessments if insolvency losses reach specified levels. 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. In recent years, participation in guaranty funds has not had a material effect on our results of operations.
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.
Changes in Legislation and Regulation
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, notably Florida, Georgia, Illinois, Missouri, Ohio, Texas, and West Virginia, enacted tort reform legislation in the previous decade as a response to a rapid deterioration in loss trends. These reforms are generally thought to have contributed to the improvement in the overall loss trends in those states, although loss trends have also been favorable in states that did not pass any type of tort reform. In states where these reforms are perceived to have improved the MPLlegal climate for liability defendants, we have experienced an increase in competition.

12


The Missouri tort reform statutes were overturned in 2012, the Illinois and Georgia statutes were overturned in 2010, and challenges to tort reform are underway in most states where tort reforms have been enacted. Other state reforms may also be overturned, although we cannot predict with any certainty how appellate courts will rule. We monitor developments on a state-by-state basis and make business decisions accordingly.
Tort reform proposals are considered from time to time at the Federal level. 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.
The Patient Protection and Affordable Care Act of 2010, otherwise known as the Healthcare Reform Act was passed and signed into law in March 2010. Although someSome of the more significant provisions of the Act have alreadynot yet become effective, the most comprehensiveand effects from enacted provisions will become effective beginning in 2013.Wemay gradually increase. We do not expect that the

13


provisions thus far enacted will have a significant direct effect on our business, but specific regulations to implement the law are still being written.
The Healthcare Reform Act is expected to have a significant impact on the practice of medicine in future years and could have unanticipated or indirect effects on our business or alter the risk and cost environments in which we and our insureds operate. These risks include: reduced operating margins that may cause physicians and hospitals to join in larger groupings which are more likely to utilize self-insured solutions for MPLHCPL insurance products; use of electronic medical records may lead to additional medical malpractice litigation or increase the cost of litigation; and patient dissatisfaction may increase due to greater strain on the patient-physician relationship.relationship; there may be an overall increase in healthcare costs which would increase loss costs for claims involving bodily injury; and additional health conditions may be identified as work-related which could increase the number of workers' compensation claims. Conversely, it is anticipated that there will be growth in the number of ancillary healthcare providers that will become customers for MPLHCPL products. We are unable to predict with any certainty the effect that the Healthcare Reform Act or future related legislation will have on our insureds or our business.
The Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act) was passed in July 2010. Although provisions of the Act do not appear to materially affect our business, the Act establishes new regulatory oversight of financial institutions. As detailed regulations are developed to implement the provisions of the Dodd-Frank Act, there may be changes in the regulatory environment that affect the way we conduct our operations or the cost of compliance, or both.
OtherOne of the federal initiatives couldgovernment bodies created by the Dodd-Frank Act was the Federal Insurance Office (FIO) which, in December 2013, released a proposal on insurance modernization and improvement of the system of insurance regulation in the United States. Although the FIO is prohibited from directly regulating the business of insurance, it has authority to represent the United States in international insurance matters and has limited power to preempt certain types of state insurance laws. The recent proposal advocates significantly greater federal involvement in insurance regulation and identifies necessary reforms by the states to preclude further consideration of direct federal regulation. While the proposal does not necessarily imply that the federal government will displace state regulation completely, it does recommend more of a hybrid approach to insurance regulation. We cannot predict whether the proposals will be proposed, including additional patient protection legislation that could ultimately affectadopted or what impact, if any, such proposals or, if enacted, such laws may have on our business. We are unable to predict the likelihoodbusiness, financial condition or results of any particular type of legislation becoming effective or the ramifications to our business.operations.
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.
Terrorism Risk Insurance Act
The Federal Terrorism Risk Insurance Act (TRIA) was initially enacted in 2002 to ensure the availability of insurance coverage for certain acts of terrorism, as defined in the TRIA. The Terrorism Risk Insurance Program Reauthorization Act of 2007 (Reauthorization Act) extended the program through December 31, 2014. The Reauthorization Act revised the definition of “Act of Terrorism” to remove the requirement that the act of terrorism be committed by an individual acting on behalf of any foreign person or foreign interest in order to be certified under the Reauthorization Act. The Reauthorization Act requires a $100 million loss event to trigger coverage. The Federal government will reimburse 85% of an insurer’s losses in excess of the insurer’s deductible, up to the maximum annual Federal liability of $100 billion.
Under the Reauthorization Act, we are required to offer terrorism coverage to our commercial policyholders in our workers' compensation line of business, for which we may, when warranted, charge an additional premium. The policyholders may or may not accept such coverage.
International
Workers' Compensation
Our segregated portfolio cell business is reinsured through our subsidiary, Eastern Re Ltd., SPC (Eastern Re), which is organized and licensed as a Cayman Islands unrestricted Class B insurance company. Eastern Re is subject to regulation by the Cayman Islands Monetary Authority (CIMA). Applicable laws and regulations govern the types of policies that the Company can insure or reinsure, the amount of capital that it must maintain and the way it can be invested, and the payment of dividends without approval by the CIMA. Eastern Re is required to maintain minimum capital of approximately $120,000 and must receive approval from the CIMA before it can pay any dividends.
Lloyd's Syndicate 1729
Syndicate 1729 is regulated in the United Kingdom by the Prudential Regulation Authority and the Financial Conduct Authority. All Lloyd's syndicates must also comply with the bylaws and regulations established by the Council of Lloyd's including submission and approval of an annual business plan and maintenance of stipulated capital levels. Also, the Council of

14


Lloyd's may call or assess a percentage of a member's underwriting capacity (currently a maximum of 3%) as a contribution to Lloyd's Central Fund, which, similar to state guaranty funds in the United States, meets policyholder obligations if a Lloyd's member is otherwise unable to do so.
The European Union's executive body, the European Commission, is implementing new capital adequacy and risk management regulations called Solvency II that would apply to businesses within the European Union. Solvency II is currently required to be implemented on January 1, 2016, and certain interim transition measures are required for 2014 and 2015. We expect to comply with the requirements in accordance with the timetable set out by the Council of Lloyd's.
Enterprise Risk Management
As a large property and casualty insurance provider, we are exposed to many risks. These risks, whether taken intentionally or unintentionally, are a function of the environment within which we operate. Since certain risks can be correlated with other risks, an event or a series of events can impact multiple areas of the Company simultaneously and have a material effect on the Company's results of operations, financial position and/or liquidity. In response to these exposures we have implemented an Enterprise Risk Management (ERM) program. Our ERM program consists of numerous processes and controls that have been designed by our senior management, with oversight by our Board of Directors, and have been implemented across our organization. We utilize ERM to identify potential risks from all aspects of our operations and to evaluate these risks in manner that is both prudent and balanced. Our primary objective is to develop a risk appetite that creates and preserves value for all of our stakeholders.
Employees
At December 31, 2012,January 1, 2014, upon completion of our merger with Eastern, we had 690962 employees, none of whom were 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. Any factor described in this report could by itself, or together with one or more other 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.
Insurance market conditions may alter the effectiveness of our current business strategy and impact our revenues.
The property and casualty insurance business is highly competitive. We compete within a fragmented market comprised of many insurers, ranging from smaller single state mono-line insurers who have an extensive knowledge of local markets to large national propertyinsurers who offer multiple product lines and casualty insurance companies, locally-based specialty companies, self-insuredwhose financial strength and resources may be greater than ours. In many instances, coverage we offer is also available through mutual entities and alternative risk transfer mechanisms (such as captive insurers and risk retention groups) whose activities are directed to limited markets in which they have extensive knowledge. Competitors include insurance companies that have substantially greater financial resources than we do, alternative risk transfer mechanisms used by hospitals purchasing physician practices, as well as mutual insurance companies and similar companies not owned by shareholders whose return on equity objectives may be lower than ours. Also, there are many opportunities for self-insurance and for participation in an alternative risk transfer mechanism, such as captive insurers or risk retention groups.
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, geographic scope, local presence, agent and client relationships, financial strength and the experience of the insurance company in the line of insurance to be written. Increased competitionActions of competitors could adversely affect our ability to attract and retain business at current premium levels, impact our market share and reduce the profits that would otherwise arise from operations.
Because we are a property and casualty insurer, our business may suffer as a result of unforeseen catastrophe losses.
As a property and casualty insurer we are exposed to claims arising out of catastrophes, primarily through our workers' compensation and Syndicate 1729 operations. Catastrophes can be caused by various events, including hurricanes, tsunamis, tornadoes, windstorms, earthquakes, hailstorms, explosions, flooding, severe winter weather and fires and may include man-made events, such as terrorist attacks or a wide-spread financial crisis. The incidence, frequency and severity of catastrophes are inherently unpredictable. While we use historical data and modeling tools to assess our potential exposure to catastrophic losses under various conditions and probability scenarios, such assessments do not necessarily accurately predict future losses or accurately measure our potential exposure. The extent of losses from a catastrophe is a function of both the total amount of insured exposure in the area affected by the event and the severity of the event.
Insurance companies are not permitted to reserve for a catastrophe until it has occurred. Although we purchase reinsurance protection for risks we believe bear a significant level of catastrophe exposure, actual losses resulting from a

15


catastrophic event or events may exceed our reinsurance protection. It is therefore possible that a catastrophic event or multiple catastrophic events could have a material adverse effect on our financial position, results of operations and liquidity.
Our results of operations and financial condition may be affected if actual insured losses differ from our loss reserves.reserves or if actual amounts recoverable under reinsurance agreements differ from our estimated recoverables.
We establish reserves as balance sheet liabilities representing our estimates of amounts needed to payresolve reported and unreported losses and thepay related loss adjustment expense.expenses. Our largest liability is our reserve for loss and loss adjustment expenses. Due to the size of our reserve for loss and loss adjustment expenses, even a small percentage adjustment to our reserve can have a material effect on our results of operations for the period in which the change is made.
The process of estimating loss reserves is complex. 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. Ultimate loss costs, even for claims with similar characteristics, can vary significantly depending upon many factors, including but not limited to, the nature of the claim, including whether or not the claim is an individual or a mass tort claim, and the personal situation of the claimant or the claimant’s family, the outcome of jury trials, the legislative and judicial climate where the insured event occurred, general economic conditions and, for MPL and medical products claims involving bodily injury, the trend of healthcare costs. Consequently, the loss cost estimation process requires actuarial skill and the application of judgment, and such estimates require periodic revision. As part of the reserving process, we review the known facts surrounding reported claims as well as historical claims data and consider the impact of various factors such as:
for reported claims, the nature of the claim and the jurisdiction in which the claim occurred;
trends in paid and incurred loss development;
trends in claim frequency and severity;
emerging economic and social trends;
trend of healthcare costs for MPLclaims involving bodily injury;
inflation and medical products claims;
inflation;levels of employment; and
changes in the regulatory legal and political environment.
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. We evaluate our reserves each period and increase or decrease reserves as necessary based on our estimate of future claims payments. An increase to reserves has a negative effect on our results of operations in the period of increase; a reduction to reserves has a positive effect on our results of operations in the period of reduction.
Our loss reserves also may be affected by court decisions that expand liability of 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. Due to uncertainties inherent in the jury system, any case that is litigated to a jury verdict has the potential to incur a loss that has a material adverse effect on our results of operations.

14


We purchase reinsurance to mitigate the effect of large losses. 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 under our reinsurance programs. We base our estimate of funds recoverable upon our expectation of ultimate losses and the portion of those losses that we estimate to be allocable to reinsurers based upon the terms and conditions of our reinsurance agreements. Given the uncertainty of the ultimate amounts of our losses, our estimates of losses and related amounts recoverable may vary significantly from the eventual outcome. Also, we estimate premiums ceded under reinsurance agreements wherein the premium due to the reinsurer, subject to certain maximums and minimums, is based in part on losses reimbursed or to be reimbursed under the agreement. Due to the size of our reinsurance balances, changes to our estimate of the amount of reinsurance that is due to us could have a material effect on our results of operations in the period for which the change is made.

16


We are exposed to and may face adverse developments involving mass tort products liability claims arising from allegedly defective medical products, including medical devices, biotechnology and diagnostic products, prescription and non-prescription pharmaceuticals, personal care products or animal healthcare products.
Establishing claim and claim adjustment expense reserves for mass tort claims is subject to uncertainties due to many factors, including expanded theories of liability, geographical location and jurisdiction of the lawsuits and the number of manufacturers and/or distributors involved. Moreover, it is difficult to estimate our ultimate liability for such claims due to evolving judicial interpretations of various tort theories of liability and defense theories, such as federal preemption and joint and several liability, as well as the application of insurance coverage to these claimsclaims.
If market conditions cause reinsurance to be more costly or unavailable, we may be required to bear increased risksrisk 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. 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 need to reduce the amount of our underwritten risk.
We cannot guarantee that our reinsurers will pay in a timely fashion or at all, and, as a result, we could experience losses.
We transfer part of our risks to reinsurance companies in exchange for part of the premium we receive in connection with the risk. Although our reinsurance agreements make the reinsurer liable to us to the extent the risk is transferred, our liability to our policyholders remains our responsibility. Reinsurers may periodically dispute our demand for reimbursement from them based upon their interpretation of the terms of our agreements or may fail to pay us for financial or other reasons. If reinsurers refuse or fail to pay us or fail to pay on a timely basis, our financial results and/or cash flows would be adversely affected and could have a material effect on our results of operations in the period in which uncollectible amounts are identified.
At December 31, 20122013 our Receivable from Reinsurersreinsurers on Unpaid Lossesunpaid losses is $191.6247.5 million and our Receivable from Reinsurersreinsurers on Paid Lossespaid losses is $4.53.2 million. As of December 31, 20122013 the estimated net amount due from four of our reinsurers exceeded $10$20 million, on an individual basis, with the largest estimated amount due from an individual reinsurer being $31.2 million.$26.0 million. A table listing significant reinsurers is provided in Item 7. Management's Discussion and Analysis, as a part of the Liquidity section, under the caption "Reinsurance".
Our claims handling could result in a bad faith claim against us.
We have been, from time to time, sued for allegedly acting in bad faith during our handling of a claim. The damages claimed in actions for bad faith may include amounts owed by the insured in excess of the policy limits as well as consequential and punitive damages. Awards above policy limits are possible whenever a case is taken to trial. These actions have the potential to have a material adverse effect on our financial condition and results of operations.
Changes in healthcare policy could have a material effect on our operations.
The Healthcare Reform Act was passed and signed into law in March 2010. While the primary provisions of the Healthcare Reform Act do not appear to directly affect our business, specific regulations to implement the law are still being written.
The Healthcare Reform Act is expected to have a significant impact on the practice of medicine in future years and could have unanticipated or indirect effects on our business or alter the risk and cost environments in which we and our insureds operate. These risks include: reduced operating margins that may cause physicians and hospitals to join in larger groupings which are more likely to utilize self-insured solutions for MPLHCPL insurance products; use of electronic medical records may lead to additional medical malpractice litigation or increase the cost of litigation; and patient dissatisfaction may increase due to

15


greater strain on the patient-physician relationship.relationship; there may be an overall increase in healthcare costs which would increase loss costs for claims involving bodily injury; and additional health conditions may be identified as work-related which could increase the number of workers' compensation claims. Conversely, it is anticipated that there will be growth in the number of ancillary healthcare providers that will become customers for MPLHCPL products. We are unable to predict with any certainty the effect that the Healthcare Reform Act or future related legislation will have on our insureds or our business.

17


Changes due to financial reform legislation could have a material effect on our operations.
The Dodd-Frank Act was passed and signed into law in July 2010. The provisions of the bill do not appear to materially affect our operations; however, the bill establishes new regulatory oversight of financial institutions and regulations to implement the Act remain in the process of development. As detailed regulations are developed to implement the provisions of the bill, there may be changes in the regulatory environment that affect the way we conduct our operations or the cost of regulatory compliance, or both. We are unable to predict with any certainty the effect that the Dodd-Frank Act will have on our business.
One of the federal government bodies created by the Dodd-Frank Act was the Federal Insurance Office (FIO) which, in December 2013, released a proposal on insurance modernization and improvement of the system of insurance regulation in the United States. Although the FIO is prohibited from directly regulating the business of insurance, it has authority to represent the United States in international insurance matters and has limited powered to preempt certain types of state insurance laws. The recent proposal advocates significantly greater federal involvement in insurance regulation and identifies necessary reforms by the states to preclude further consideration of direct federal regulation. While the proposal does not necessarily imply that the federal government will displace state regulation completely, it does recommend more of a hybrid approach to insurance regulation. We cannot predict whether the proposals will be adopted or what impact, if any, such proposals or, if enacted, such laws may have on our business, financial condition or results of operations.
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, notably Florida, Georgia, Illinois, Missouri, Ohio, Texas, and West Virginia, enacted tort reform legislation in the previous decade as a response to a rapid deterioration in loss trends.
Challenges to tort reform are underway in most states where tort reforms have been enacted. The statutes in Missouri were overturned in 2012; those in Georgia and Illinois were overturned in 2010. We cannot predict with any certainty how other state appellate courts will rule on these laws. While the effects of tort reform have been generally beneficial to our business in states where these laws have been enacted, there can be no assurance that such reforms will be ultimately upheld by the courts. Further, if tort reforms are effective, the business of providing professional liability insurance may become more attractive, thereby causing an increase in competition. In addition, the enactment of tort reforms could be accompanied by legislation or regulatory actions that may be detrimental to our business because of expected benefits which may or may not be realized. These expectations could result in regulatory or legislative action limiting the ability of professional liability insurers to maintain rates at adequate levels.
Coverage mandates or other expanded insurance requirements could also be imposed. States may also consider state-sponsored MPL insurance entities that could remove some physiciansour potential insureds from the private insurance market.
We continue to monitor developments on a state-by-state basis, and make business decisions accordingly.

18


Our performance is dependent on the business, economic, regulatory and legislative conditions of states where we have a significant amount of business.
Our top five states, Alabama,, Ohio, Texas,, Ohio, Florida and Michigan,, represented 44%43% of our gross premiums written for the year ended December 31, 20122013. Moreover, on a combined basis, Alabama,, Texas Ohio and OhioTexas accounted for 32%30%, 33%32%, and 28%33% of our gross premiums written for the years ended December 31, 20122013, 20112012 and 20102011, respectively. BecauseAdditionally, although Eastern will not be a part of these concentrations, unfavorableour consolidated results until January 1, 2014, a significant portion of Eastern's total gross premium written for the year ended December 31, 2013 was in the state of Pennsylvania. Unfavorable business, economic or regulatory conditions in any of these states could have a disproportionately greater effect on us than they would if we were less geographically concentrated.
We may be unable to identify future strategic acquisitions or expected benefits from completed and proposed acquisitions may not be achieved or may be delayed longer than expected.
Our corporate strategy anticipates growth through the acquisition of other companies or books of business. However, such expansion is opportunistic and sporadic, and there is no guarantee that we will be able to identify strategic acquisition targets in the future. Additionally, if we are able to identify a strategic target for acquisition, state insurance regulation concerning change or acquisition of control could delay or prevent us from growing through acquisitions. State insurance regulatory codes provide 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. There is no assurance that we will receive such approval from the respective insurance regulator or that such approvals will not be conditioned in a manner that materially and adversely affects the aggregate economic value and business benefits expected to be obtained and cause us to not complete the acquisition.
ThereThe Company performs thorough due diligence before agreeing to a merger or acquisition, however there is no guarantee that anythe procedures we perform will adequately identify all potential weaknesses or liabilities of the target company or potential risks to the consolidated entity.
There is also no guarantee that our recent acquisitions of Medmarc and Eastern, or acquisitions or businesses acquired in the future will be successfully integrated, and the ineffectiveintegrated. Ineffective integration of our businesses and processes may result in substantial costs or delays and adversely affect our ability to compete. The process of integrating an acquired company or business can be complex and costly, and may create unforeseen operating difficulties and expenditures. Potential problems that may arise include, among other reasons, business disruption, loss of

16


customers and employees, the ineffective integration of underwriting, claims handling and actuarial practices, the increase in the inherent uncertainty of reserve estimates for a period of time until stable trends reestablish themselves within the combined organization, diversion of management time and resources to acquisition integration challenges, the cultural challenges associated with integrating employees, increased operating costs, assumption of greater than expected liabilities, or inability to achieve cost savings,savings. Furthermore, claims may be asserted by either the policyholders or shareholders of any acquired entity related to payments or other issues associated with the acquisition and merger into the assumption of greater than expected liabilities.consolidated entity. Such claims may prove costly or difficult to resolve or may have unanticipated consequences.
If we are unable to maintain favorable financial strength ratings, 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 and the financial strength 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 and debt obligations and are not directed toward the protection of equity investors.
Our principal operating subsidiaries hold favorable claims paying ratings with A.M. Best, Fitch and Moody’s. Claims paying 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 or the rating agencies significantly change the rating criteria that are used to determine ratings, we may not maintain our favorable financial strength ratings from the rating agencies. A downgrade or involuntary withdrawal of any such rating could limit or prevent us from writing desirable business.

Our business could be adversely affected by the loss or consolidation of independent agents, agencies, or brokers.brokers or brokerage firms.
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 their services and allegiance. These agents and brokers may choose to direct business to competing insurance companies.
Our success is dependent upon our ability to effectively design and execute our business strategy and to adequately and appropriately serve our customers.
The Company depends upon the skill and work product of our officers and employees in executing our business strategy. While management and the Board of Directors ("the Board" or "our Board") monitor the strategic direction of the Company, strategic changes could be made that are not supportable by our capital base. In addition, our business could potentially be impacted if we are unable to align our strategy with the expectations of our stakeholders. The operations of the Company are also heavily dependent upon the delivery of superior customer service across a broad customer base, by which negative feedback from agents, insureds or internal staff could result in a loss of revenue for the Company.
Our business could be adversely affected by the loss of one or more of our senior executives.
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 regularly reviews succession planning relating to our Chief Executive Officer as well as other senior officers. Mr. Starnes, our Chief Executive Officer and President, has indicated to the Board that he has no immediate plans for retirement.

20


Provisions in our charter documents, Delaware law and state insurance law may impede attempts to replace or remove management or may 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. We currently have no preferred stock outstanding, and no present intention to issue any shares of preferred stock. In addition, our Corporate Governance Principles provide that the Board, subject to its fiduciary duties, will not issue any series of preferred stock for any defense or anti-takeover purpose, for the purpose of implementing any stockholders rights plan, or with features intended to make any acquisition more difficult or costly without obtaining stockholder approval. However, because the rights and preferences of any series of preferred stock may be set by the Board 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 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 ProAssurance would be presumed if any person or entity acquires 10% (5% in Alabama) or more of our outstanding common stock, unless the applicable insurance regulator determines otherwise. These provisions apply even if the offer may be considered beneficial by stockholders.
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, meet other holding company financial obligations, or pay dividends to shareholders. 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 in Item 1 Insuranceunder the caption "Insurance Regulatory Matters.Matters".
Regulatory requirements or changes to regulatory requirements could have a material effect 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.

18


These regulations may impede or impose burdensome conditions on rate changes or other actions that we may desire to take in order to enhance our results of operations. 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.
Also, certain states sponsor MPL insurance entities which affectsaffect the amount and type of MPLliability coverages purchased by healthcare providers in the sponsoring state. Changes to the number of state sponsored entities of this type could result in a large number of healthcare practitionersinsureds changing the amount and type of coverage purchased from private insurance entities such as ProAssurance.
As a result of our acquisition of Eastern, we own a subsidiary domiciled in the Cayman Islands and subject to the laws of the Cayman Islands and regulations promulgated by the CIMA. Failure to comply with these laws, regulations and requirements could result in consequences ranging from a regulatory examination to a regulatory takeover of our Cayman subsidiary, which could potentially impact profitability of the workers' compensation alternative market solutions offered through this subsidiary.
Syndicate 1729 is regulated in the United Kingdom by the Prudential Regulation Authority and the Financial Conduct Authority. All Lloyd's syndicates must also comply with the bylaws and regulations established by the Council of Lloyd's. Failure to comply with bylaws and regulations could affect our ability to underwrite as a Lloyd's Syndicate in the future and therefore affect our profitability. Changes in bylaws and regulations could also affect the profitability of the operations.

The European Union's executive body, the European Commission, is implementing new capital adequacy and risk management regulations called Solvency II that would apply to businesses within the European Union. Solvency II is currently required to be implemented on January 1, 2016, and certain interim transition measures are required for 2014 and 2015. We are unable to predict with any certainty the effect that such regulations will have on the profitability of Lloyd's or Syndicate 1729.
As a member of the Lloyd's market and a capital provider to Lloyd's Syndicate 1729 we are subject to certain risks which could materially and adversely affect us.
As a member of the Lloyd's market we are obligated to contribute to the Lloyd's Central Fund and to pay levies to Lloyd's as well as our ongoing exposure to levies and charges in order to underwrite at Lloyd's. Whenever a member of Lloyd's is unable to pay its policyholder obligations, such obligations may be payable by the Lloyd's Central Fund. If Lloyd's determines that the Central Fund needs to be increased, it has the power to assess premiums levies on current Lloyd's members up to 3% of a member's underwriting capacity in any one year. We do not believe that any assessment is likely in the foreseeable future and have not provided an allowance for such an assessment. However, based on our 2014 estimated underwriting capacity at Lloyd's of £43.2 million ($71.5 million), the December 31, 2013 exchange rate of 1.6557 dollars per GBP and assuming the maximum 3% assessment, we could be assessed up to $2.1 million in 2014.
As a participant in Lloyd's of London, Syndicate 1729 is subject to certain risks and uncertainties, including the following:
its reliance on insurance and reinsurance brokers and distribution channels to distribute and market its products;
its obligation to pay levies to Lloyds;
its obligations to maintain funds to support its underwriting activities; its risk-based capital requirement being assessed periodically by Lloyd's and being subject to variation;
its reliance on ongoing approvals from Lloyd's and various regulators to conduct its business, including a requirement that its Annual Business Plan be approved by Lloyd's before the start of underwriting for each account year;
its financial strength rating is derived from the rating assigned to Lloyd's, although it has limited ability to directly affect the overall Lloyd's rating; and
its reliance on Lloyd's trading licenses in order to underwrite business outside the United Kingdom.
The guaranty fund assessments that we are required to pay to state guaranty associations may increase or our participation in mandatory risk retention pools could be expanded and our 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 insurance companies that have become insolvent. 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 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. In 2013 and 2012, net guaranty fund assessments approximated $0.3totaled less than $0.1 million, while in 2011, refunds/recoupments exceeded assessments by $0.1 and approximately $0.3 million,. respectively. Our practice is to accrue for insurance insolvencies when notified of assessments. We are not able to reasonably estimate assessments or develop a meaningful range of possible assessments prior to notice because the guaranty funds do not provide sufficient information for development of such estimates or ranges.
Certain states have established risk pooling mechanisms that offer insurance coverage to individuals or entities who are otherwise unable to purchase coverage from private insurers. Authorized property and casualty insurers in these states are generally required to share in the underwriting results of these pooled risks, which are typically adverse. Should our mandatory participation in such pools be increased or if the assessments from such pools increased, our results of operations and financial condition would be negatively affected, although that was not the case in 2013, 2012 or 2011.

Our investment results will fluctuate as interest rates change.
Our investment portfolio is primarily comprised of interest-earning assets, marked to market each period. Thus, prevailing economic conditions, particularly changes in market interest rates, may significantly affect our results of operations. Significant movements in interest rates potentially expose us to lower yields or lower asset values. Changes in market interest rate levels generally affect our net income to the extent that reinvestment yields are different than the yields on maturing securities. 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 investments are subject to credit, prepayment risk and other risks.
A significant portion of our total assets ($($3.9 billion or 81%77%) at December 31, 20122013 are financial instruments whose value can be significantly affected by economic and market factors beyond our control including, among others, the unemployment rate, the strength of the domestic housing market, the price of oil, changes in interest rates and spreads, consumer confidence, investor confidence regarding the economic prospects of the entities in which we invest, corrective or remedial actions taken by the entities in which we invest, including mergers, spin-offs and bankruptcy filings, the actions of the U.S. government, and global perceptions regarding the stability of the U.S. economy. Adverse economic and market conditions could cause investment losses or other-than-temporary impairments of our securities, which could affect our financial condition, results of operations, or cash flows.
At December 31, 20122013 approximately 13%10% of our investment portfolio is invested in mortgage and asset-backed securities. We utilize ratings determined by Nationally Recognized Statistical Rating Organizations (NRSROs) (Moody’s, Standard & Poor’s, and Fitch) as an element of our evaluation of the credit worthiness of our securities. The ratings are subject to error by the agencies; therefore, we may be subject to additional credit exposure should the rating be misstated.

At December 31, 2012 all asset-backed securities were carried at fair value.
(2)Guaranteed by Ginnie Mae, Fannie Mae or Freddie Mac
Persistent value declines in the U.S. housing and real estate markets as well as the U.S. economic downturn have resulted in increases in delinquencies and losses with respect to mortgage- and asset-backed securities. The value of our mortgage- and asset-backed securities is subject to the risk that some of these investments may default or become significantly impaired. Such defaults or impairments would result in realized investment losses.
Our asset-backed securities are also subject to prepayment risk. A prepayment is the unscheduled return of principal. When rates decline, the propensity for refinancing may increase and the period of time we hold our asset-backed securities may shorten due to prepayments. Prepayments may cause us to reinvest cash proceeds at lower yields than the retired security. Conversely, as rates increase, and motivations for prepayments lessen, the period of time we hold our asset-backed securities may lengthen, causing us to not reinvest cash flows at the higher available yields.
At December 31, 20122013 the fair value of our state/municipal portfolio was $1.2 billion (amortized cost basis of $1.1 billion). While our state/municipal portfolio had a high credit rating (AA on average) which indicates a strong ability to pay, there is no assurance that there will not be a credit related event which would cause fair values to decline. The economic downturn in preceding years lessened tax receipts and other revenues in many states and their municipalities and the frequency of credit downgrades of these entities has increased.
Our tax credit partnership interests are subject to risks related to the potential forfeiture of the tax credits and all or a portion of the previously claimed tax credits. Loss of the tax credits might occur if the property owner fails to meet the specified requirements of planning, constructing and operating the property or if the property fails to generate the projected tax credits. At December 31, 2013 the carrying value of our tax credit partnership interests was approximately $142.2 million.
U.S. Government debt rating has been downgraded.rating.
In August 2011,U.S Government securities are no longer rated with the highest possible rating by one of the major rating agencies, downgraded the rating of U.S. Government debt. Otherand there is potential for a further downgrade or for additional rating agencies have indicated that they will likelyto also downgrade U.S.U. S. Government debt in 2013 if significant fiscal reform is not implemented.securities. The rating agencies have also indicated that debt instruments of issuers dependent upon federal support and distributions, including state and local municipalities, may also be downgraded, but this has not yet occurred to any widespread extent except with respect to U.S. Agency debt or U.S. Agency guaranteed debt. If ratings downgrades become more widespread,occur, the average credit rating of our investment portfolio will be reduced. Due to the unpredictable nature of this situation, we are unable to provide a reliable estimate regarding the extent to which our portfolio might be affected. As of December 31, 20122013 debt securities represented 88%79% of our total investments and included U.S. Government debt, U.S. Agency debt, and U.S. Agency guaranteed debt having a combined fair value of $598462 million and state and municipal securities having a combined fair value of $1.2 billion.
In a period of market illiquidity and instability, the fair values of our investments are more difficult to assess and our assessments may prove to be greater or less than amounts received in actual transactions.
In accordance with applicable GAAP, we value 96%94% of our investments at fair value and the remaining 4%6% at cost, equity, or cash surrender value. See Notes 1, 3 and 4 of the Notes to Consolidated Financial Statements for additional information.

23


We determine the fair value of our investments using quoted exchange or over-the-counter (OTC) prices, when available. At December 31, 20122013, we valued approximately 7%13% of our investments in this manner. When exchange or OTC quotes are not available, we estimate fair values based on broker dealer quotes and various other valuation methodologies, which may require us to choose among various input assumptions and which requires us to utilize judgment. At December 31, 20122013 approximately 89%81% of our investments were valued in this manner. When markets exhibit muchsignificant volatility, there is more risk that we may

20


utilize a quoted market price, broker dealer quote, valuation technique or input assumption that results in a fair value estimate that is either over or understated as compared to actual amounts received upon disposition or maturity of the security.
Our Board may decide that our financial condition does not allow the continued payment of a quarterly cash dividend, or requires that we reduce the amount of our quarterly cash dividend.
Our Board approved a cash dividend policy in September 2011, most recently paid at $0.250.30 per share.share for the three months ended December 31, 2013. However, any decision to pay future cash dividends is subject to the Board’s final determination after a comprehensive review of the Company’s financial performance, future expectations and other factorsdeemed relevant by the Board.
Our ability to issue additional debt or letters of credit or other types of indebtedness on terms consistent with current debt is subject to market conditions, economic conditions at the time of proposed issuance, and the results of ratings reviews. Also, our current credit agreement requires that our debt to capital ratio be 0.35 to 1.0 or less, and the issuance of debt by one of our insurance subsidiaries requires regulatory approval, both of which may limit or prohibit the issuance of additional debt.
During 2013 we were able to issue $250 million of unsecured Senior Notes Payable due in 2023 at a 5.3% interest rate, and we obtained a secured letter of credit for £41.9 million (approximately $69.3 million at December 31, 2013 at a rate of prime plus 400 basis points. There is no guarantee that additional debt could be issued on similar terms in the future as rates available to us may change due to changes in the economic climate or shifts in the yield curve may occur or an increase in our level of debt may result in rating agencies lowering our debt rating. Also, our insurance subsidiaries must obtain regulatory approval before incurring additional debt. A further restriction is that our credit facility agreement requires that our consolidated debt to capital ratio (0.10 to 1.0 at December 31, 2013) be 0.35 to 1.0 or less.
Resolution of uncertain tax matters and changes in tax laws or taxing authority interpretations of tax laws could result in actual tax benefits or deductions that are different than we have estimated, both with regard to amounts recognized and the timing of recognition. Such differences could affect our results of operations or cash flows.
Our provision for income taxes, our recorded tax liabilities and net deferred tax assets, including any valuation allowances, are recorded based on estimates. These estimates require us to make significant judgments regarding a number of factors, including, among others, the applicability of various federal and state laws, the interpretations given to those tax laws by taxing authorities, courts and ProAssurance, the timing of future income and deductions, and our expected levels and sources of future taxable income. We believe our tax positions are supportable under tax laws and that our estimates are prepared in accordance with GAAP. Additionally, from time to time there are changes to tax laws and interpretations of tax laws which could change our estimates of the amount of tax benefits or deductions expected to be available to us in future periods. In either case, changes to our prior estimates would be reflected in the period changed and could have a material effect on our effective tax rate, financial position, results of operations and cash flow. The reinsurance portion of our workers' compensation business is domiciled in the Cayman Islands. Changes in Cayman Island tax laws could result in the loss of profitability of that business.
We are subject to U.S. federal and various state income taxes. We are periodically under routine examination by various federal, state and local authorities regarding income tax matters and our tax positions could be successfully challenged; the costs of defending our tax positions could be considerable. Our estimate of our potential liability for known uncertain tax positions is reflected in our financial statements and considers the Notice of Proposed Adjustment (NOPA) received in 2012, as discussed in the following paragraph. As of December 31, 20122013 our currentwe had a federal income tax liability wasreceivable of approximately $19.3 million, which included our$27 million. We also had a liability for unrecognized current tax benefits of $4.8 million, and we had net deferred tax liabilitiesassets of approximately $14.6 million.$1.8 million. Unrecognized tax benefits at December 31, 20122013, if recognized, would not affect the effective tax rate but would accelerate the payment of tax.
In December 2012 we received a NOPA related to our federal returnsNotice of Proposed Adjustment (NOPA) from the IRS which disallows a substantial portion of the loss and loss adjustment expense deductions taken for the 2009 and 2010 taxfiscal years which would substantially reduce the deduction allowed for our loss and loss adjustment expenses and would thereby increase taxes dueour current tax liability by approximately $130 million. The proposed adjustment affects onlyIn January 2013 we submitted a comprehensive written protest of the NOPA to the IRS Office of Appeals regarding certain issues within the NOPA, all of which related to the timing of our deduction and any payment acceleration resulting fromdeductions. During the fourth quarter of 2013, we reached a tentative settlement of all contested Federal income tax issues for the related

Other non-contested issues addressed by the NOPA would not increaseare expected to result in a net federal income tax expense for the current or prior periods,refund, exclusive of statutory interest, of approximately $9.6 million. We believe that might be assessed on past-due taxes, if any. Any payments would come outour tentative terms of our cash and investments and could reduce future investment earnings. We disagreesettlement with and are contesting the position taken by the IRS but cannot reliably predictwill be documented and finalized during 2014. In January 2013 we made a $20.6 million protective tax payment to the timing ofIRS in order to reduce potential interest assessments. We expect the final resolution orprotective payment to also be refunded once the ultimate outcome.settlement is finalized.
New or changes in existing accounting standards, practices and/or policies, and alsoas well as subjective assumptions, estimates and judgments by management related to complex accounting matters could significantly affect our financial results.results or our ability to maintain investor confidence and shareholder value.
U.S. generally accepted accounting principles (GAAP) and related accounting pronouncements, implementation guidelines and interpretations with regard to a wide range of matters that are relevant to our business, such as revenue recognition, estimation of losses, determination of fair value, asset impairment (particularly investment securities and goodwill) and tax matters, are highly complex and involve many subjective assumptions, estimates and judgments. Changes in these rules or their interpretation or changes in underlying assumptions, estimates, or judgments could significantly change our reported or expected financial performance or financial condition. See Note 1 of the Notes to Consolidated Financial Statements for the discussion ona description of our significant accounting policies.
ProAssurance is primarily a holding company of insurance subsidiaries which are required to comply with statutory accounting principles (SAP). SAP and its components are subject to review by the NAIC and state insurance departments. The NAIC Accounting Practices and Procedures manualManual provides that a state insurance department may allow insurance companies that are domiciled in that state to depart from SAP by granting them permitted non-SAP accounting practices. This permission may allow forpermit a competitor or competitors to use a more favorable treatment to competitors.accounting policy.
It is uncertain whether or how SAP might be revised or whether any revisions will have a positive or negative effect. It is also uncertain whether any changes to SAP or its components or any permitted non-SAP accounting practices granted to our competitors will negatively affect our financial results or operations. See the Insurance Regulatory Matters section in Item 1 for the full discussion on regulatory matters.
Our interpretation, integration and/or compliance with new or changes to existing pronouncements by GAAP or SAP could materially impact us as a publicly traded company as it relates to investor confidence and shareholder value.
We are subject to numerous NYSE and SEC regulations including insider trading regulations, Regulation FD, and regulations requiring timely and accurate reporting of our operating results as well as certain events and transactions. Non-compliance with these regulations could subject us to enforcement actions by the NYSE or the SEC, and could affect the value of our shares and our ability to raise additional capital.
The Company carefully adheres to NYSE and SEC requirements as the loss of trading privileges on the NYSE or an SEC enforcement action could have a significant financial impact on the Company. Failure to comply with various SEC reporting and record keeping requirements could result in a decline in the value of our stock or a decline in investor confidence which could directly impact our ability to efficiently raise capital. Failure to adhere to NYSE requirements could result in fines, trading restriction or delisting.
The operations of the Company are heavily reliant upon the Company's reputation as an ethical business organization providing needed services to its customers.
The Company's positive reputation is critical to its role as an insurance provider and as a publicly traded company. The Board adopted a Code of Ethics and Conduct and management is heavily focused on the integrity of our employees and third party suppliers, agents or brokers. Illegal, unethical or fraudulent activities perpetrated by an employee or one of our third party agencies or brokers for personal gain could expose the Company to a potential financial loss.

2125


A natural disaster or pandemic event, or closely related series of events, could cause loss of lives or a substantial loss of property or operational ability at one or more of the Company's facilities.
The Company's disaster preparedness encompasses our Business Continuity Plan, Disaster Recovery Plan, Operations Plan, and Pandemic Response Plan. Our disaster preparedness is focused on maintaining the continuity of the Company's data processing and telephone capabilities as well as the use of alternate and temporary facilities in the event of a natural disaster or medical event. The Company's plans are reviewed during the insurance department examinations of the statutory insurance companies. While the Company has plans in place to respond to both short- and long-term disaster scenarios, the loss of certain key operating facilities or data processing capabilities could have a significant impact on Company operations.
The operations of the Company are dependent upon the availability, integrity and security of our internal technology infrastructure and that of certain third parties. Any significant disruption of these infrastructures could result in unauthorized access to Company data or reduce our ability to conduct business effectively, or both.
The Company is dependent upon its technology infrastructure and that of certain third parties to operate and report financial and other Company information accurately and timely. The Company has focused resources on securing and preserving the integrity of our data processing systems and related data. Additionally, the Company evaluates the integrity and security of the technology infrastructure of third parties that process or store data that the Company considers to be significant. However, there is no guarantee that measures taken to date will completely prevent unauthorized access to our technological infrastructure or that of our third party service providers or our data. Should such unauthorized access occur, our normal operations could be disrupted or unauthorized internal or external knowledge or misuse of confidential Company data could occur, all of which could be harmful to the Company from both a financial and reputational perspective.

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 to those statements which accompany this report. A glossary of insurance terms and phrases is available on the investor section of our website. Throughout the discussion, references to “ProAssurance”, “PRA”, “Company”, “we”, “us” and “our” refer to ProAssurance Corporation and its consolidated subsidiaries. The discussion contains certain forward-looking information that involves risks and uncertainties. As discussed under “Forward-Looking Statements”, our actual financial condition and operating results could differ significantly from these forward-looking statements.
ProAssurance Overview
We are an insurance holding company and our operating results are primarily derived from the operations of our insurance subsidiaries, which provide professional liability insurance for healthcare professionals and facilities, professional liability insurance for attorneys, liability insurance for medical technology and life sciences risks, and, effective January 1, 2014, workers' compensation insurance. We are also a 58% capital provider to Syndicate 1729, which began underwriting and reinsuring a range of property and casualty insurance lines effective January 1, 2014.
Critical Accounting Estimates
Our Consolidated Financial Statements are prepared in conformity with U.S. generally accepted accounting principles (GAAP). Preparation of these financial statements requires us to make estimates and assumptions that affect the amounts we report on those statements. We evaluate these estimates and assumptions on an ongoing basis based on current and 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; reported results of operations may be materially affected by changes in these estimates and assumptions.
Management considers the following accounting estimates 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
The largest component of our liabilities is our reserve for losses and loss adjustment expenses (reserve("reserve for losseslosses" or reserve)"reserve"), and the largest component of expense for our operations is incurred losses and loss adjustment expenses (also referred to as “loss and loss adjustment expenses”, “incurred losses”, “losses incurred”, and “losses”). Incurred losses reported in any period reflect our estimate of losses incurred related to the premiums earned in that period as well as any changes to our estimates of the reserve established for losses of prior periods.
As of December 31, 2013 our reserves are almost entirely comprised of long-tail risk exposures. The estimation of professional liabilitylong-tailed insurance losses is inherently difficult and is the subject ofto significant judgment on the part of management. Loss costs, even for claims with similar characteristics, can vary significantly depending upon many factors, including but not limited to: the nature of the claim, andincluding whether or not the claim is an individual or a mass tort claim, the personal situation of the claimant or the claimant's family, the outcome of jury trials, the legislative and judicial climate where the insured event occurred,any potential litigation may occur, general economic conditions and, for MPL claims involving bodily injury, the trend of healthcare costs. Professional liability claims are typically resolved over anLong-tailed insurance is characterized by the extended period of time typically required to resolve claims, 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 significant judgment, and such estimates require periodic revision.
Our reserves are established by management after taking into consideration a variety of factors including premium rates, claims frequency, historical paid and incurred loss development trends, the effect of inflation, general economic trends, the legal and political environment, and the conclusions reached by our internal and consulting actuaries. We update and review the data underlying the estimation of our reserve for losses each reporting period and make adjustments to loss estimation assumptions that we believe best reflect emerging data. Both our internal and consulting actuaries perform an in-depth review of our reserve for losses on at least a semi-annual basis using the loss and exposure data of our insurance subsidiaries. We partition our reserves by accident year, which is the year in which the claim becomes our liability. As claims are incurred (reported) and claim payments are made, they are aggregated by accident year for analysis purposes. We also partition our reserves by reserve type: case reserves and IBNR reserves. Case reserves are established by our claims department based upon the particular circumstances of each reported claim and represent our estimate of the future loss costs (often referred to as expected losses) that will be paid on reported claims. Case reserves are decremented as claim payments are made and are periodically adjusted upward or downward as estimates regarding the amount of future losses are revised; reported loss is the case reserve at any point in time plus the claim payments that have been made to date. IBNR reserves represent our estimate of losses that have been incurred but not reported to us and future developments on losses that have been reported to us.

At a high level our reserving process can be broadly grouped into two areas,areas: the establishment of initial or current accident year reserves and the re-estimation of reserves for prior year's loss reserves. Activityaccident years. A summary of the activity in our net reserve for losses during 20122013, 20112012 and 20102011 is summarizedprovided in the Liquidity and Capital Resources and Financial Condition - Losses section that follows.
Initial Reserve EstimatesEstimates-Current Accident Year
In the current environment, and taking into consideration current claims trends, we believe we are pricing our business today to a 75% loss ratio, however, considerableConsiderable judgment is required in the pricing of our business and in establishing our initial reserves for a givenany current accident year. Due to the lack of available data for bothyear period, as there is limited open andor closed claims data available for the initial

Table of Contents

a current accident year period at the time reserves for that period are estimated. Accordingly, in establishing our initial reserves for an accident year, in general we rely heavily rely on the loss assumptions that arewere used to price business during the accident year, as our pricing reflects our analysis of loss costs that we expect to incur relative to the business being priced. For our HCPL business (89% of our gross written premiums in 2013, 96% in 2012 and 97% in 2011) we set initial reserves at the average loss ratio used in our pricing, plus an additional margin in consideration of the historical loss volatility we and others in the industry have experienced. For our business. Historically,HCPL business our target loss ratio during recent accident years has approximated 75% and at present, we utilizethe margin for loss ratios that are approximatelyvolatility has ranged from 8 to 10 percentage points, above the ratios we believe we have achieved inproducing an overall average initial loss ratio for our pricing for the current accident year.HCPL business of approximately 85%. We believe thisuse of a margin for volatility considers inherent risks associated with our rate development process and the historic volatility of professional liability losses (the industry has experienced accident year loss ratios as high as 163% and as low as 57%53% over the past 30 years) and produces a reasonable best estimate of the reserves required to cover actual ultimate unpaid losses. InA similar practice is followed for our professional legal liability business. Our medical technology and life sciences products liability business is more varied, and policies are individually priced based on the current environmentrisk characteristics of the policy. Therefore, for this equatesbusiness we establish initial reserves using our most recently developed actuarial estimates of losses expected to an initial loss ratiobe incurred based on factors which include: results from prior analysis of approximately 85%similar business, industry indications, observed trends and judgment. The products liability line of business exhibits similar volatility to HCPL, and the actuarial estimate includes a provision for volatility.
Severity is defined as comparedthe average cost of resolving claims and the severity trend is the increase or decrease in severity from period to an average loss ratio of approximately 74% targeted in our pricing.period. Although we remain uncertain regarding the ultimate severity trend as discussed in following paragraphs,to project into the considerationfuture due to the long-tailed nature of our business, we have given consideration to observed lower loss costs in setting our rates. For our HCPL business this practice has resulted in rate reductions in recent years. OnFor example, on average, excluding our podiatry business acquired in 2009, we have gradually reduced the premium rates we charge on our standard physician renewal business (our largest HCPL line) by approximately 16%17% from the beginning of 2006 to 2012December 31, 2013. Loss ratios for the current accident years have thus remained fairly constant because expected loss reductions have been reflected in our rates.
ReestimationRe-estimation of Prior Years' Loss Reserves
Process
The foundation of our reserve re-estimation process is an actuarial analysis that is performed by both our internal and consulting actuaries. The very detailed analysis projects ultimate losses on a line of business, geographic, coverage layer and accident year basis. The procedure is intended to balance the use of the most representative data for each partition, capturing its unique patterns of development and trends. In all there are approximatelyover 140 different partitions of our business for purposes of this analysis. We believe that the use of consulting actuaries provides an independent view of our loss data as well as a broader perspective on industry loss trends.
The analysis performed by the consulting actuaries analyzes each partition of our business in a variety of ways and uses multiple actuarial methodologies in performing these analyses, including:
Bornhuetter-Ferguson (Paid and Reported) Method
Paid Development Method
Reported Development Method
Average Paid Value Method
Average Reported Value Method
Backward Recursive Development Method
The Adjusted Reported and the Adjusted Paid Methods
A brief description of each method follows.
Bornhuetter-Ferguson Method. We use both the Paid and the Reported Bornhuetter-Ferguson methods. The Paid method assigns partial weight to initial expected losses for each accident year (initial expected losses being the first established case

32


and IBNR reserves for a specific accident year) and partial weight to paid to-date losses. The Reported method assigns partial weight to the initial expected losses and partial weight to current expected losses. The weights assigned to the initial expected losses decrease as the accident year matures.
Paid Development and Reported Development Method. These methods use historical, cumulative losses (paid losses for the Paid Development Method, reported losses for the Reported Development Method) by accident year and develop those actual losses to estimated ultimate losses based upon the assumption that each accident year will develop to estimated ultimate cost in a manner that is analogous to prior years, adjusted as deemed appropriate for the expected effects of known changes in the claim payment environment (and case reserving environment for the Reported Development Method), and, to the extent necessary, supplemented by analyses of the development of broader industry data.
Average Paid Value and Average Reported Value Methods. In these methods, average claim cost data (paid claim cost for the Average Paid Value Method and reported claim cost for the Reported Value Method) is developed to an ultimate average cost level by report year based on historical data. Claim counts are similarly developed to an ultimate count level. The average claim cost (after rounding and adjustment, if necessary, to accommodate report year data that is not considered to be predictive) is then multiplied by the ultimate claim counts by report year to derive ultimate loss and ALAE.
Backward Recursive Development Method. This method is an extrapolation of the movements in case reserve adequacy in order to estimate unpaid loss costs. Historical data showing incremental changes to case reserves over progressive time periods is used to derive factors that represent the ratio of case reserve values at successive maturities. Historical claims payment data showing the additional payments in progressive time periods is used to derive factors that represent the portion of a case reserve paid in the following period. Starting from the most mature period, after which all of the case reserve is paid and the case reserve is exhausted, the next prior ultimate development factor for the prior case reserve can be calculated as the case factor times the established ultimate development factor plus the paid factor. For each successive prior maturity, the ultimate

28

Table of Contents

development factor is calculated similarly. The result of multiplying the ultimate development factor times the case reserve is the total indicated unpaid amount.
The Adjusted Reported and the Adjusted Paid Methods. These methodsare based on the premise that the relative change in a given accident year's adjusted reported loss estimates (Adjusted Reported Method) or adjusted paid losses (Adjusted Paid Method) from one evaluation point to the next is similar to changes observed for earlier accident years at the same evaluation points. In the Adjusted Reported Method reported loss estimates are adjusted to reflect a common case reserve adequacy basis. In the Adjusted Paid Method, the historical paid loss experience is adjusted to reflect a common claim settlement rate basis. We principally use these methods to evaluate reserves for our legal liability coverages.
Generally, methods such as the Bornhuetter-Ferguson method are used on more recent accident years where we have less data on which to base our analysis. As time progresses 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. These methods emphasize different aspects of loss reserve estimation and provide a variety of perspectives for our decisions.
Certain of the methodologies utilized to estimate the ultimate losses for each partition of our reserves consider the actual amounts paid. Paid data is particularly influential when a large portion of known claims have been closed, as is the case for older accident years. In selecting a point estimate for each partition, management considers the extent to which trends are emerging consistently for all partitions and known industry trends. Thus, actual, rather than estimated severity trends are given consideration. When actual severity trends are lower than those estimated at the time that reserves were previously established, the recognition of favorable development is indicated. This is particularly true for older accident years where our actuarial methodologies give more weight to actual loss costs (severity).
The various actuarial methods discussed above are applied in a consistent manner from period to period. In addition, we perform statistical reviews of claims data such as claim counts, average settlement costs and severity trends when establishing our reserves.
We utilize the selected point estimates of ultimate losses to develop estimates of ultimate losses recoverable from reinsurers, based on the terms and conditions of our reinsurance agreements. An overall estimate of the amount receivable from reinsurers is determined by combining the individual estimates. Our net reserve estimate is the gross reserve point estimate less the estimated reinsurance recovery.
Use of Judgment
Even though the actuarial process is highly technical, it is also highly judgmental, both as to the selection of the data used in the various actuarial methodologies (e.g., initial expected loss ratios and loss development factors) and in the interpretation of the output of the various methods used. Each actuarial method generally returns a different value and for the more recent accident years the variations among the various methodologies can be significant. For each partition of our reserves, the results of the various methods, along with the supplementary statistical data regarding such factors as closed with and without

33

Table of Contents

indemnity ratios, claim severity trends, the expected duration of such trends, changes in the legal and legislative environment and 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 is based upon the judgment of management taking into consideration the actuarial methods and other environmental factors discussed previously. For each partition of our reserves, we select a point estimate with due regard for the age, characteristics and volatility of the subset of the business, the volume of data available for review and past experience with respect to the accuracy of estimates. The series of selected point estimates is then combined to produce an overall point estimate for ultimate losses.
Given the historicalpotential for unanticipated volatility of the MPL linefor long-tailed lines of business, we are cautious in giving full credibility to emerging trends that, when more fully mature, may lead to the recognition of either favorable or adverse development of our losses. There may be trends, both positive and negative, reflected in the numerical data both within our own information and in the broader MPL marketplace that mitigate or reverse as time progresses and additional data becomes available. This is particularly true for our HCPL business which has historically exhibited significant volatility as previously discussed.
Over the past several years the most influential factor affecting our analysis of reserves and the development recognized has been the changes,change, or lack thereof, in the severity of claims, particularly for our HCPL claims.
Severity is defined as the average cost of resolving claims. The severity trend assumption is a key assumption for both pricing models and actuarial estimation of reserves. The severity trend is an explicit component of our pricing models, whereas in our reserving process the severity trend's impact is implicit. Our estimate of this trend and our expectations about changes in this trend impact a variety of factors, from the selection of expected loss ratios to the ultimate point estimates established by management.
Because of the implicit and wide-ranging nature of severity trend assumptions on the loss reserving process it is not practical to specifically isolate the impact of changing severity trends. However, because severity is an explicit component of our HCPL pricing process we can better isolate the impact that changing severity can have on our loss costs and loss ratios as regards our pricing models.models for this business component. Our current HCPL pricing model assumes a severity trend of 2% to 3% in most states and lines of business. If the severity trend were to be higher by 1 percentage point, the impact would be an increase in our expected loss ratio of 3.2 percentage points. An increase in the severity trend of 3 percentage points would result in a 10.1 percentage point increase in our expected loss ratio. Due to the long tailed nature of MPLour claims and the previously discussed historical volatility of loss costs, selection of a severity trend assumption is a subjective process that is inherently likely to prove inaccurate over time. Given this long-tail and the previously discussed historical volatility of loss costs, we are generally cautious in making changes

29

to the severity assumptions within our pricing model.models. Also of note is that all open claims and accident years are generally impacted by a change in the severity trend, which compounds the effect of such a change.
From 2004 to 2009 both our internal and consulting actuaries have observed an unprecedented reduction in the frequency of HCPL claims (or number of claims per exposure unit) that cannot be attributed to any single factor, which has complicated the selection of an appropriate severity trend for our pricing models.models for these lines. It has also made it more challenging to factor severity into the various actuarial methodologies discussed above. We believe that much of the reduction in claim frequency is the result of a decline in the filing of frivolous lawsuits that have historically been dismissed or otherwise result in no payment of indemnity on the part of our insureds. With fewer frivolous claims being filed we expect that the claims that are filed have the potential for greater average losses, or greater severity. As a result, we cannot be certain as to the impact this decline will ultimately have on the average cost of claims. Based on a weighted average of payments, only 85% are resolved after eight years for a given accident year. Due to this long tail, it can take several years before we are ablecontinue to determine whatbe uncertain of the full impact if any, has resulted fromof the observed decline in frequency and whether there is a related increase in severity.
Loss Development
We recognized net favorable development related to prior accident years of $222.7 million for the year ended December 31, 2013 (including favorable development of $6.9 million related to reserves acquired in the January 1, 2013 Medmarc acquisition), $272.0 million for the year ended December 31, 2012, and $325.9 million for the year ended December 31, 2011, and .
$234.0 million for the year ended December 31, 2010. In support of our concern that the decline in frequency will result in a higher severity trend, we have seensaw our closed-with-indemnity-payment ratio (i.e., the number of claims closed with an indemnity or loss payment as compared to the total number of closed claims) for our claims increase from 7% in 2005 to 14%15% iin n 20132012 (percentages exclude Medmarc claims). While this trend has been in keeping with our expectations, the anticipated increase in severity incorporated into our loss assumptions has not occurred. Rather, we have experienced lower than expected severity which has been the primary driver of the favorable development recognized in recent years.

An extended period of time is required to get a clear estimate of the loss cost for a given accident year. As an example, looking at the 2008 accident year, we had resolved 71.2% of the known claims by the end of 2010, 83.1% of the known claims by the end of 2011, and 90.3% of the known claims by the end of 2012.2012, and 94.6% of the known claims by the end of 2013. These statistics are based on the number of reported claims; since many non-meritorious claims are resolved early, percentages of ultimate loss payments known at the same points in time are considerably lower. A similar pattern can be seen in each open accident year as demonstrated in the table below.
Historically we have resolved more than 85% of our physician and hospital professional liability claims with no indemnity payment and generally these claims are the first to be resolved. As an accident year matures, the number of claims resolved with indemnity payments progressively increases. In a similar fashion, we typically expend more in loss adjustment expenses (legal fees) as claims mature.

Based upon the additional claims closed during 20122013, 20112012 and 20102011, as shown above, and the continuation of better than expected severity trends, management reduced its expected ultimate losses in each of these years resulting in the recognition of corresponding amounts of favorable development in the income statements of those periods. At December 31, 20102012 and 2011 management reserve estimates for the three most recent prior accident years (which have closed claim percentages below 85%) were more heavily influenced by the initial reserves estimates set for these years, while estimatesmoderated to reflect consideration of better than anticipated claims experience observed during the periods. Estimates for older accident years with higher percentages of closed claims were more heavily influenced by the more moderate severity trend observed during the period,periods, particularly with regard to claims closed during the period. At December 31, 2012 and 2011 the continued lack of increase in the severity trend, in spite of the increase in the ratio of claims closed with indemnity, influenced management's judgment both in regard to the older accident years where this trend has more fully played out and in regard to the more recent accident years. The increased favorable development recognized in 2011 as compared to 2010 is largely attributable to the initial effect of giving greater consideration to the moderated severity trend.periods. Management continued to reflect approximately the same level of consideration of the moderated trend in its estimate of the reserve required at December 31, 2012;2013; however, the effect was not as pronounced as that recorded in 2012 as that initially recorded inand 2011.
This can be seen in looking at both the absolute amount of favorable reserve development recognized for the less developed accident years as well as the size of such development when compared to established ultimates for those same accident years at the end of the preceding calendar year. The following table provides this information for years ended December 31, 20122013, 20112012 and 20102011 with respect to the three then most recent prior accident years:

We recognized $6.9 million of development related to the reserves acquired from Medmarc, representing a 2.0% reduction to the ultimates for accident years 2004 to 2012 as of January 1, 2013, the date of acquisition. The development recognized related primarily to product liability reserves established for 2005 to 2010 accident years, and reflects improved claims experience during 2013 as compared that anticipated by the actuarial methodologies used to established ultimates as of January 1, 2013.

Variability of Loss Reserves
As previously noted, the number of data points and variables considered and the subjective process followed in establishing our loss reserve makes it impractical to isolate individual variables and demonstrate their impact on our estimate of loss reserves. However, to provide a better understanding of the potential variability in our reserves, we have modeled implied reserve ranges around our single point net reserve estimates for our 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 our 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.
We have used this modeled statistical distribution to calculate an 80% and 60% confidence interval for the potential outcome of our net reserve for losses. The high and low end points of the distributions are as follows:
 Low End Point Carried Net Reserve High End Point
80% Confidence Level$1.4181.407 billion $1.8631.825 billion $2.3742.300 billion
60% Confidence Level$1.5351.520 billion $1.8631.825 billion $2.1612.105 billion
Any change in our estimate of net ultimate losses for prior years is reflected in net income in the period in which such changes are made. Over the past several years such changes have been to reduce our estimate of net ultimate losses, resulting in a reduction of reported losses for the period and a corresponding increase in income.
Due to the size of our reserve for losses and the large number of claims outstanding at any point in time, even a small percentage adjustment to our total reserve estimate could have a material effect on our results of operations for the period in which the adjustment is made.
Acquired Reserves
The acquisition of Medmarc increased our loss reserves by $201.1 million, which represented the fair value of Medmarc's loss reserves at the time of the acquisition. The estimated fair value was calculated as the present value of the expected underlying net cash flows, including a 5% profit margin and a 5% risk premium. Expected net cash flows were derived from the expected loss payment patterns included in an actuarial analysis of Medmarc reserves performed as of December 31, 2012. Approximately 85% of the reserves assumed in the Medmarc acquisition are products liability reserves and approximately 15% are professional liability reserves.
Reinsurance
We use insurance and reinsurance (collectively, “reinsurance”) to provide capacity to write larger limits of liability, to provide protection against losses in excess of policy limits, and to stabilize underwriting results in years in which higher losses occur. The purchase of reinsurance does not relieve us from the ultimate risk on our policies, but it does provide reimbursement for certain losses we pay.
We make a determination of the amount of insurance risk we choose to retain based upon numerous factors, including our risk tolerance and the capital we have to support it, the price and availability of reinsurance, volume of business, level of experience with a particular set of claims and our analysis of the potential underwriting results. We purchase reinsurance from a number of companies to mitigate concentrations of credit risk. We utilize a reinsurance broker to assist us in the placement of our reinsurance programprograms and in the analysis of the credit quality of our reinsurers. The determination of which reinsurers we choose to do business with is based upon an evaluation of thetheir then-current financial strength, rating and stability of prospective reinsurers.stability.
We evaluate each of our ceded reinsurance contracts at inception to confirm that there is sufficient risk transfer to allow the contract to be accounted for as reinsurance under current accounting guidance. At December 31, 20122013, all ceded contracts were accounted for as risk transferring contracts.
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 under our reinsurance programs. We base our estimate of funds recoverable upon our expectation of ultimate losses and the portion of those losses that we estimate to be allocable to reinsurers based upon the terms and conditions of our reinsurance agreements. Our assessment of the collectability of the recorded amounts receivable from reinsurers considers the payment history of the reinsurer, publicly available financial and rating agency data, our interpretation of the underlying contracts and policies, and responses by reinsurers.

Given the uncertainty inherent in our estimates of losses and related amounts recoverable from reinsurers, these estimates may vary significantly from the ultimate outcome.

Table of Contents

Under the terms of certain of our reinsurance agreements, the amount of premium that we cede to our reinsurers is based in part on the losses we recover under the agreements. Therefore we make an estimate of premiums ceded under these reinsurance agreements subject to certain maximums and minimums. Any adjustments to our estimates of either balanceslosses recoverable under our reinsurance agreements or the premiums owed under our agreements are reflected in then-current operations. Due to the size of our reinsurance balances, an adjustment to these estimates could have a material effect on our results of operations for the period in which the adjustment is made.
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 significant collection difficulties due to the financial condition of any reinsurer as of December 31, 20122013; however, periodically, reinsurers may periodically dispute our demand for reimbursement from them based upon their interpretation of the terms of our agreements. We have established appropriate reserves for any balances that we believe may not be ultimately collected. Should future events lead us to believe that any reinsurer will not meet its obligations to us, adjustments to the amounts recoverable would be reflected in the results of current operations. Such an adjustment has the potential to be material to the results of operations in the period in which it is recorded; however, we would not expect such an adjustment to have a material effect on our capital position or our liquidity.
Investment Valuations
We record the majority of our investments at fair value as shown in the table below. The distribution of our investments based on GAAP fair value hierarchies (levels) was as follows:
Distribution by GAAP Fair Value Hierarchy December 31, 2012Distribution by GAAP Fair Value Hierarchy December 31, 2013

Fair value7% 87% 2% 96%13% 78% 3% 94%

Total Investments      100% 100%
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. All of our fixed maturity and equity security investments are carried at fair value. Our short-term securities are carried at amortized cost, which approximates fair value.
Because of the number of securities we own and the complexity and cost of developing accurate fair values, we utilize multiple independent pricing services to assist us in establishing the fair value of individual securities. The pricing services provide fair values based on exchange traded prices, if available. If an exchange traded price is not available, the pricing services, if possible, provide a fair value that is based on multiple broker/dealer quotes or that has been developed using pricing models. Pricing models vary by asset class and utilize currently available market data for securities comparable to ours to estimate the fair value for our security. The pricing services scrutinize market data for consistency with other relevant market information before including the data in the pricing models. The pricing services disclose the types of pricing models used and the inputs used for each asset class. Determining fair values using these pricing models requires the use of judgment to identify appropriate comparable securities and to choose a valuation methodology that is appropriate for the asset class and available data.
The pricing services provide a single value per instrument quoted. We review the values provided for reasonableness each quarter by comparing market yields generated by the supplied value versus market yields observed in the market place. We also compare yields indicated by the provided values to appropriate benchmark yields and review for values that are unchanged or that reflect an unanticipated variation as compared to prior period values. In addition, we compare provided information for consistency with our other pricing services, known market data and information from our own trades, considering both values and valuation trends. We also review weekly trades versus the prices supplied by the services. If a supplied value appears unreasonable, we discuss the valuation in question with the pricing service and make adjustments if deemed necessary. To date, our review has not resulted in any changes to the values supplied by the pricing services.
The pricing services do not provide a fair value unless an exchange traded price or multiple observable inputs are available. As a result, the pricing services may provide a fair value for a security in some periods but not others, depending upon the level of recent market activity for the security or comparable securities.

Table of Contents

Level 1 Investments
Fair values for our equity and a portion of our short-term securities are determined using exchange traded prices. There is little judgment involved when fair value is determined using an exchange traded price. In accordance with GAAP, for disclosure purposes we classify securities valued using an exchange traded price as Level 1 securities.
Level 2 Investments
Most fixed income securities do not trade daily, and thus exchange traded prices are generally not available for these securities. However, market information (often referred to as observable inputs or market data, including but not limited to, last reported trade, non-binding broker quotes, bids, benchmark yield curves, issuer spreads, two sided markets, benchmark securities, offers and recent data regarding assumed prepayment speeds, cash flow and loan performance data) is available for most of our fixed income securities. We determine fair value for a large portion of our fixed income securities using available market information. In accordance with GAAP, for disclosure purposes we classify securities valued based on multiple market observable inputs as Level 2 securities.
Level 3 Investments
When a pricing service does not provide a value for one of our fixed maturity securities, management estimates fair value using either a single non-binding broker quote or pricing models that utilize market based assumptions which have limited observable inputs. The process involves significant judgment in selecting the appropriate data and modeling techniques to use in the valuation process. For disclosure purposes we classify fixed maturity securities valued using limited observable inputs as Level 3 securities.
We also classify as Level 3 our investment interests that are carried at fair value based on a fund-provided net asset value (NAV) for our interest. All investments valued in this manner are LP or LLC interests that hold debt and equity securities. At December 31, 20122013 interests valued using a fund-provided NAV totaled $33.772.1 million, or 1%2% of total investments, and were classified as part of our Investment in Unconsolidated Subsidiaries.
Investments - Other Valuation Methodologies
Certain of our investments, in accordance with GAAP for the type of investment, are measured using methodologies other than fair value. At December 31, 20122013 these investments had a carrying value of approximately $170.8248.8 million, which represented approximately 4%6% of total investments, as shown in the following table. Additional information about these investments is provided in Notes 23 and 34 of the Notes to Consolidated Financial Statements.

Investment Impairments
We evaluate our investments on at least a quarterly basis for declines in fair value that represent other than temporary impairment (OTTI). In all instances weWe consider an impairment to be an OTTI if we intend to sell the security or if we believe we will be required to sell the security before we fully recover the amortized cost basis of the security. Otherwise, we consider various factors in our evaluation, depending upon the type of security, as discussed below.
For debt securities, we consider whether we expect to fully recover the amortized cost basis of the security, based upon consideration of some or all of the following:
third party research and credit rating reports;
the current credit standing of the issuer, including credit rating downgrades;

3439

Table of Contents

the extent to which the decline in fair value is attributable to credit risk specifically associated with an investmentthe security or its issuer;
our internal assessments and those of our external portfolio managers regarding specific circumstances surrounding an investment,a security, which can cause us to believe the investmentsecurity is more or less likely to recover its value than other investmentssecurities with a similar structure;
for asset-backed securities, the origination date of the underlying loans, the remaining average life, the probability that credit performance of the underlying loans will deteriorate in the future, and our assessment of the quality of the collateral underlying the loan;
failure of the issuer of the security to make scheduled interest or principal payments;
any changes to the rating of the security by a rating agency;
recoveries or additional declines in fair value subsequent to the balance sheet date; and
our intent to sell and whether it is more likely than not we will be required to sell the investmentsecurity before the recovery of its amortized cost basis.
In assessing whether we expect to recover the cost basis of debt securities, particularly asset-backed securities, we must make a number of assumptions regarding the cash flows that we expect to receive from the security in future periods. These judgments are subjective in nature and may subsequently be proved to be inaccurate.
We evaluate our cost method interests in LPs/LLCs for OTTI by considering whether there has been a decline in fair value below the recorded value, which involves assumptions and estimates. We receive a report from each of the LPs/LLCs at least quarterly which provides us a NAV for our interest in the LP/LLC.interest. The NAV is based on the fair values of securities held by the LP/LLC as determined by the LP/LLC manager. We consider the most recent NAV provided, the performance of the LP/LLC relative to the market, the stated objectives of the LP/LLC, the cash flows expected from the LP/LLC and audited financial statements of the entity, if available, in considering whether an OTTI exists.
Our investments in tax credit partnerships are evaluated for OTTI by comparingconsidering both qualitative and quantitative factors which include: whether cash flow projectionsflows currently expected from the investment, primarily tax benefits, equal or exceed the carrying value of the underlying projects generatinginvestment, whether currently expected cash flows are less than those expected at the tax credits to our recorded basis,time the investment was acquired, and by considering our ability and intent to utilizehold the tax credits generated byinvestment until the investments.recovery of its carrying value.
We also evaluate our holdings of FHLB securities for impairment. We consider the current capital status of the FHLB, whether the FHLB is in compliance with regulatory minimum capital requirements, and the FHLB’s most recently reported operating results.

Deferred Policy Acquisition Costs
Policy acquisition costs (primarily commissions, premium taxes and underwriting salaries) which are directly related to the successful acquisition of new and renewal premiums are capitalized as deferred policy acquisition costs and charged to expense as the related premium revenue is recognized. We evaluate the recoverability of our deferred policy acquisition costs each reporting period, and any amounts estimated to be unrecoverable are charged to expense in the current period. As of December 31, 2013 we have not determined that any amounts are unrecoverable. Prior to our adoption of the new Financial Accounting Standards Board (FASB) guidance on January 1, 2012, we capitalized all internal selling agent and underwriter salary and benefit costs, including costs associated with unsuccessful contract efforts. Adoption of the new guidance had no material effect on our results of operations or financial position.
Deferred Taxes
Deferred federal income taxes arise from the recognition of temporary differences between the bases of assets and liabilities determined for financial reporting purposes and the bases determined for income tax purposes. Our temporary differences principally relate to loss reserves, unearned premiums, deferred policy acquisition costs, and unrealized investment gains (losses) and investment impairments.. Deferred tax assets and liabilities are measured using the enacted tax rates expected to be in effect when such benefits are realized. We review our deferred tax assets quarterly for impairment. If we determine that it is more likely than not that some or all of a deferred tax asset will not be realized, a valuation allowance is recorded to reduce the carrying value of the asset. In assessing the need for a valuation allowance, management is required to make certain judgments and assumptions about our future operations based on historical experience and information as of the measurement period regarding reversal of existing temporary differences, carryback capacity, future taxable income (including its capital and operating characteristics) and tax planning strategies. We did not have any significant valuation allowances as of December 31, 2013.

Unrecognized Tax Benefits
We evaluate tax positions taken on tax returns and recognize positions in our financial statements when it is more likely than not that we will sustain the position upon resolution with a taxing authority. If recognized, the benefit is measured as the

35


largest amount of benefit that has a greater than fifty percent probability of being realized. We review uncertain tax positions each period, considering changes in facts and circumstances, such as changes in tax law, interactions with taxing authorities and developments in case law, and make adjustments as we consider necessary. Adjustments to our unrecognized tax benefits may affect our income tax expense, and settlement of uncertain tax positions may require the use of cash. At December 31, 20122013, our currentliability for unrecognized tax liability includedbenefits approximated $4.8 million for unrecognized tax benefits,, and$1.4 million for related accrued interest.interest approximated $1.3 million.
Goodwill
Management evaluates the carrying value of goodwill annually during the fourth quarter. If, at any time during the year, events occur or circumstances change that would more likely than not reduce the fair value below the carrying value, we also evaluate goodwill at that time. We evaluate goodwill as one reporting unit because we operate as a single operating segment and our segment components are economically similar. We estimate the fair value of our reporting unit on the evaluation date based on market capitalization and an expected premium that would be paid to acquire control of our Company (a control premium). We then perform a sensitivity analysis using a range of historical stock prices and control premiums. We concluded as of our last evaluation date, October 1, 20122013, that the fair value of our reporting unit exceeded the carrying value and no adjustment to impair goodwill was necessary.
Goodwill is recognized in conjunction with acquisitions as the excess of the purchase consideration for the acquisition over the fair value of identifiable assets acquired and liabilities assumed. GoodwillThe fair value of identifiable assets and liabilities, and thus goodwill, is subject to redetermination within a measurement period of up to one year following completion of an acquisition. During 2013 goodwill was reduced by $1.9 million primarily related to the after tax effect of the re-determination of the fair value of the reserve for losses associated with a business combination completed in late 2012.
Accounting Changes
We did not adopt any accounting changes during 2013 that had a material effect on our results of operations nor are we aware of any accounting changes not yet adopted as of $3.4 millionDecember 31, 2013 was recognized in 2012 relatedthat would have a material effect on our results of operations or financial position. Note 1 of the Notes to acquisitions completed during the period.Consolidated Financial Statements provides additional detail regarding accounting changes.
ProAssurance Overview
We are an insurance holding company and our operating results are primarily derived from the operations of our insurance subsidiaries, which principally write medical and other professional liability insurance.
Corporate Strategy
Our mission is to be the preferred source of professional liability protection by providing unparalleled claims defense, highly responsive customer service and innovative risk management while maintaining our commitment to long-term financial strength. We are a industry leading specialty insurance company with extensive expertise in medical professional liability, errors and omission coverage for attorneys and, beginning in 2013 with our acquisition of Medmarc, products liability for the medical device and sciences industry. Our customer focus combined with our financial strength, strong reputation and proven ability to manage claims has played a role in our ability to expand our operations while maintaining profitability. We have historically utilized acquisitions of companies and books of business as a means of expanding into new geographic areas and product lines, although we cannot predict the timing of those transactions with any certainty. We emphasize disciplined underwriting and prudent pricing in order to achieve profitability as opposed to emphasizing premium growth and achieving market share gain at any cost. In addition to prudent risk selection and pricing, we seek to control our underwriting results through effective claims management, and have fostered a strong culture of defending non-meritorious claims. We differentiate ProAssurance from many other national writers by tailoring our claims handling to the legal climate of each state.
Through our market-based underwriting and claims office structure, we develop a deep understanding of market conditions, which enables us to respond to changes in the liability climate and adapt our underwriting and claims strategies as needed. Our market-based focus allows us to maintain active relationships with our customers, understand the importance of the professional identity and reputation of our insureds and thus be more responsive to their needs. We use advisory boards and operational committees to help us better understand the challenges facing our insureds and ways in which we can assist them. We believe the extensive experience of medical and legal professionals throughout our organization, especially that of our senior management team, enhances our understanding of the medical/legal environment. We emphasize our pledge that our insureds will be treated fairly in all of our conduct with them and that all of our business actions will be informed by the core values that guide our organization: integrity, respect, doctor involvement in healthcare insurance activities, collaboration, communication and enthusiasm. We believe our strategy allows us to compete on a basis other than price alone.Key Performance Measures
We have sustained our financial stability during difficult market conditions through responsible pricing and loss reserving practices and through conservative investment practices. We are committed to maintaining prudent operating and financial leverage and to conservatively investing our assets. We recognize the importance that our customers and producers place on the financial strength of our principal insurance subsidiaries and we manage our business to protect our financial security.
We consider a number of performance measures, including the following:
The net loss ratio is calculated as net losses incurred divided by net premiums earned and is a component of underwriting profitability.
The underwriting expense ratio is calculated as underwriting, policy acquisition and operating expenses incurred divided by net premiums earned and is a component of underwriting profitability.

36


The combined ratio is the sum of the underwriting expense ratio and the net loss ratio and measures underwriting profitability.
The investment income ratio is calculated as net investment income divided by net premiums earned and measures the contribution investment earnings provides to our overall profitability.
The operating ratio is the combined ratio, less the investment income ratio. This ratio provides the combined effect of investment income and underwriting profitability.
The tax ratio is calculated as total income tax expense divided by income (loss) before income taxes and measures our effective tax rate.
Return on equity (ROE) is calculated as net income for the period divided by the average of beginning and ending shareholders’ equity. This ratio measures our overall after-tax profitability and shows how efficiently invested capital is being used.
Growth in book value. Book value per share is calculated as total shareholders’ equity at the balance sheet date divided by the total number of common shares outstanding. This ratio measures the net worth of the company to shareholders on a per-share basis. Growth in book value per share is an indicator of overall profitability.

41


We particularly focus on our combined ratio and investment returns, both of which directly affect our return on equity (ROE)ROE and growth of our book value. Historically we targeted a long-term average ROE of 12% to 14%. Given the persistent low interest rate environment which prevails in the United States and the soft pricing environment for our products, the realization of this long-term ROE target in the next few years will likely prove difficult.
Our emphasis on rate adequacy, selective underwriting, effective claims management and prudent investments is a key factor in our achievement of our ROE target. We closely monitor premium revenues, losses and loss adjustment costs, and underwriting and policy acquisition expenses. Our overall investment strategy is to focus on maximizing current income from our investment portfolio while maintaining safety, liquidity, duration and portfolio diversification. While we engage in activities that generate other income, such activities, principally insurance agency services, do not constitute a significant use of our resources or a significant source of revenues or profits.
Growth Opportunities and Outlook
We expect our long-term growth to come through controlled expansion of our existing operations and through the acquisition of other specialty insurance companies or books of business. Growth through acquisition is often opportunistic and cannot be predicted.
We operate in very competitive markets and in addition toface strong competition from other insurance companies we are seeingfor all of our insurance products. Healthcare professional liability insurance represents a trendsubstantial portion of our gross premiums written (89% in 2013) and the healthcare market has been trending toward the formation of larger medical practice groups, and the employment of physicians by hospitals. Frequently, given the size of these organizations, they choose toLarge medical groups and facilities frequently manage their medicalhealth care professional liability exposure outside of the traditional insurance marketplace using self-insured mechanisms and other risk sharing arrangements. In response to these trends, we offer products designed to provide greater risk sharing options to hospitals and large physician groups.
We believe our emphasis on fair treatment of our insureds and other important stakeholders through our commitment to “Treated Fairly” has enhanced our market position and differentiated us from other insurers. We will continue to usepractice the values of “Treated Fairly” in all of our activities, and we believe that as we reach more customers with this message we will continue to improve retention and add new insureds.
In 2013, weWe have expanded our lines of business in new directions by acquiring Medmarc, an underwriter of products liability insurance for medical technology and life sciences companies, who also underwriteson January 1, 2013, and Eastern, a bookprovider of legal professional liability insurance.workers' compensation insurance, on January 1, 2014. We have also been a consistent acquirer of other physician insurers, most recently IND in 2012, APS in 2010 and PICA in 2009. Other 2009 acquisitions included an insurer focused on the legal professional liability market and an agency largely focused on the professional liability needs of allied healthcare providers. We continue to see new opportunities from each of the acquisitions and believe each will provide organic growth through expansion in their existing markets and relationships.
Accounting Changes Had Eastern been a part of ProAssurance during 2013, the composition of our gross premiums written, excluding Eastern segregated portfolio cell premiums, would have been as follows: 69% healthcare professional liability, 22% workers' compensation, 5% products liability and 4% legal professional liability. Eastern's segregated portfolio cells business primarily generated earnings from fee revenues, which totaled $7.2 million for 2013.
Eastern is a holding company specializing in workers' compensation insurance products and services, including its segregated portfolio cell business. Eastern profits from the segregated portfolio cell business are principally from service fees. Eastern's consolidated net assets totaled $136.8 million at December 31, 2013.
Late in 2013, we completed the process of becoming a corporate member of Lloyd's of London, an internationally recognized specialist insurance market. We did not adopt any accounting changes during 2012 that had a material effect on our results of operations nor are we aware of any accounting changes not yet adoptedthe majority (58%) capital provider to Syndicate 1729, which began underwriting and reinsuring business as of January 1, 2014. The remaining capital for Syndicate 1729 is provided by unrelated third parties, including private names and other corporate members. We have committed £47.3 million ($78.3 million at December 31, 2012 that would2013) of capital for the first year of Syndicate 1729 operations and have a material effect ontotal capital commitment through 2019 of up to $200 million. Syndicate 1729 will cover a range of property and casualty insurance and reinsurance lines, and has a maximum underwriting capacity of £75 million ($124.2 million at December 31, 2013) for the 2014 underwriting year, of which £43.2 million ($71.5 million at December 31, 2013) is our results of operations or financial position.

Liquidity and Capital Resources and Financial Condition
Overview
ProAssurance Corporation is a holding company and is a legal entity separate and distinct from its subsidiaries. Because the holding company has no other business operations, dividends from its operating subsidiaries represent a significant source of funds for its obligations, including debt service and shareholder dividends. At December 31, 20122013, we held cash and liquid investments of approximately $357.0400.2 million outside our insurance subsidiaries that were available for use without regulatory approval,approval. Our holding company also has $196.2150 million available under a revolving credit agreement, as discussed in this section

42


under the heading "Debt." During 2013, our credit facility.insurance subsidiaries paid dividends of $298 million, including extraordinary dividends of $5 million. Our insurance subsidiaries, in aggregate, are permitted to pay dividends of approximately $309243 million over the course of 20132014 without the prior approval of state insurance regulators. However, theThe 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. During 2012, our insurance subsidiaries paid dividends of approximately $278.5 million, including extraordinary dividends of $25.0 million.
Operating Activities and Related Cash Flows
The principal components of our operating cash flows are the excess of premiums collected and net investment income over losses paid and operating costs, including income taxes. Timing delays exist between the collection of premiums and the payment of losses associated with the premiums. Premiums are generally collected within the twelve-month period after the policy is written, while our claim payments are generally paid over a more extended period of time. Likewise, timing delays exist between the payment of claims and the collection of any associated reinsurance recoveries. Our operating activities provided positive cash flows of approximately $91.338.6 million, $159.491.3 million, and $139.2159.4 million for the years ended December 31, 20122013, 20112012 and 20102011, respectively.

(1)The reduction in premium receipts reflected lower premium volume in 2013 exclusive of acquisitions as well as the effect of the timing of premium receipts on several large policies.
(2)Reinsurance contracts are generally for premiums written in a specific annual period, but, absent a commutation agreement, remain in effect until all claims under the contract have been resolved. Some contracts require annual settlements while others require settlement only after a number of years have elapsed, thus the amounts paid can vary widely from period to period.
(3)The timing of our net loss payments varies from period to period because the process for resolving claims is complex and occurs at an uneven pace depending upon the circumstances of the individual claim.
(4)The net increase in tax payments during 2013 was attributable to:
A $20.6 million protective tax payment made in 2013 related to a dispute with the Internal Revenue Service (IRS), as discussed in further detail in this section under the heading "Taxes."
An $8.3 million decrease in the final tax payments made during 2013 for the prior fiscal year.
A $3.4 million decrease in estimated tax payments during 2013 for current fiscal year.
GAAP requires that excess tax benefits recognized when shares are issued under stock compensation plans be reflected as a reduction to operating cash flows and as an increase to financing cash flows in the period the shares are issued. Such excess tax benefits were $4.9 million lower in 2013 as compared to 2012.
(5)Net cash used by acquisitions reflected the payments of transaction costs, loss payments made by the acquired companies related to prior accident years, and normal expense payments of the acquired companies for which the timing of the payment differs from the recognition of the expense.
(6)Cash paid for expenses related to the start-up of Syndicate 1729, which were principally professional fees.

(1)The reduction in premium receipts reflected lower premium volume in 2012, exclusive of a volume decline related to two-yeartwenty-four month term policies and a volume increase related to tail policies. The premium from two-year term policies is included in gross written premium in the period in which the policy is written, but has little effect on timing of premium receipts since half of the written amount is billed in the second term. Tail policies are typically collected in the period written.
(2)Reinsurance contracts are generally for premiums written in a specific annual period, but, absent a commutation agreement, remain in effect until all claims under the contract have been resolved. Some contracts require annual settlements while others require settlement only after a number of years have elapsed, thus the amounts paid can vary widely from period to period.
(3)
The timing of our net loss payments varies from period to period because the process for resolving claims is complex and occurs at an uneven pace depending upon the circumstances of the individual claim. The increase in loss payments for 2012 primarily reflected a greater number of claims resolved with large indemnity payments, a portion of which was recovered under existing reinsurance agreements. The additional loss payments were not isolated to any one state or to any specific risk groups. Loss payments made during 2012 were included in the data considered by our actuaries and by our Management in determining their best estimate of losses incurred during 2012.

38


(4)We are party to certain contracts that involve claims handling but do not transfer insurance risk. As required by GAAP, receipts and disbursements for these contracts are not considered as receipts of premium or payments of losses, but rather are considered as deposits received or returned. These contracts do not constitute a significant business activity for us.
(5)The decrease in cash received for investments primarily reflected the decrease in net investment income as well as timing differences of interest receipts between periods.
(6)(4)The decrease in cash paid for other expenses was principally attributable to non-recurring payments of APS integration costs, primarily compensation-related, during 2011.
(7)(5)The net increase in tax payments during 2012 was attributable to:
A $7.4$7.4 million increase in the final payments for the prior fiscal year, partially offset by a $4.8$4.8 million decrease in estimated tax payments for the current year.
There were no Federal tax refunds in 2012. In 2011 refunds approximated $17.3 million.
$17.3 million.
GAAP requires that excess tax benefits recognized when shares are issued under stock compensation plans reducebe reflected as a reduction to operating cash flows and an increase to financing cash flows in the period the shares are issued. Such excess tax benefits were $5.3$5.3 million greater in 2012 as compared to 2011.
The above increases to tax related outflows were offset by:
Payments of $5.9$5.9 million made in 2011 for the 2008 and 2007 tax years as a result of federalFederal tax return audits conducted by the Internal Revenue Service. The payments reduced tax liabilities recognized prior to January 1, 2011 and did not increase or decrease 2011 tax expense.

(1)The decline in premium receipts is primarily attributable to reduced premium volume. Exclusive of two-yeartwenty-four month term policies and the business acquired from APS, gross written premiums were lower in 2011.
(2)Reinsurance contracts are generally for premiums written in a specific annual period, but, absent a commutation agreement, remain in effect until all claims under the contract have been resolved. Some contracts require annual settlements while others require settlement only after a number of years have elapsed, thus the amounts paid can vary widely from period to period.
(3)The timing of our net loss payments varies from period to period because the process for resolving claims is complex and occurs at an uneven pace depending upon the circumstances of the individual claim. Net loss payments are also subject to reinsurance recoveries under existing reinsurance agreements.
(4)The increase in tax payments primarily reflects:
An increase in estimated tax payments of $16.1 million during 2011 as compared to 2010.
Payments of $5.9 million made in 2011 for the 2008 and 2007 tax years as a result of Federal tax return audits conducted by the Internal Revenue Service, as previously discussed.Service. The payments reduced tax liabilities recognized prior to January 1, 2011 and did not increase or decrease 2011 tax expense.
The above increases to tax payments were partially offset by greater Federal tax refunds in 2011 of $15.9 million. Principally, refunds from capital loss carry backs were higher in 2011 than in 2010 and a refund associated with the APS 2010 pre-acquisition period was received in 2011.

(1)The decrease in premium receipts reflects the decline in gross written premium, exclusive of the premium decline that is attributable to policies written on a two-year term. Additionally, approximately $3 million of the decrease in premium receipts is due to premium credits granted to PICA policyholders as part of the acquisition.
(2)Reinsurance contracts are generally for premiums written in a specific annual period, but, absent a commutation agreement, remain in effect until all claims under the contract have been resolved. Some contracts require annual settlements while others require settlement only after a number of years have elapsed, thus the amounts paid can vary widely from period to period.
(3)The decrease in losses reflects lower paid losses at our subsidiaries other than PICA of approximately $69 million offset by an increase in PICA losses paid of $18 million. The PICA increase is principally due to an additional three months of PICA activity in 2010. The timing of our loss payments varies from period to period because the process for resolving claims is complex and occurs at an uneven pace depending upon the circumstances of the individual claim. Net loss payments are also subject to reinsurance recoveries under existing reinsurance agreements.
(4)In 2009 we paid a judgment in favor of Columbia Hospital for Women Medical Center, Inc. that was entered against our subsidiary, ProAssurance National Capital Insurance Company (PRA National), prior to our acquisition of PRA National. We established a liability related to the judgment and accrued post trial interest at the time PRA National was acquired in 2005.
(5)The increase in tax payments primarily reflects:
An increase in estimated tax payments for the current year of $17.0 million, which includes payments for pre-acquisition taxes of $3.4 million related to the acquisition of APS.
A decrease in the final payments for the prior fiscal year of $13.0 million.
A $1.6 million increase in the excess tax benefit expected from the issuance of shares under stock compensation arrangements.
An increase in state and other tax payments of $2.3 million.
These increases to tax payments were offset by an increase in Federal tax refunds received in 2010 of $4.2 million.

Losses
The following table, known as the Analysis of Reserve Development, 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. As noted in the table, ProAssurance has completed various acquisitions over the ten year period which have affected original and re-estimated gross and net reserve balances as well as loss payments.
The table includes losses on both a direct and an assumed basis and is net of anticipated 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 reserve for losses 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 reserve for losses; 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 is not appropriate to extrapolate future redundancies or deficiencies based on this table.

40


The following may be helpful in understanding the Analysis of Reserve Development:
The line entitled “Reserve for losses, undiscounted and net of reinsurance recoverables” reflects our reserve for losses and loss adjustment expense, less the receivables from reinsurers, each as reported in our 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 additionalthe remaining net 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 estimated our reserve for losses utilizing the management and actuarial processes discussed in Critical Accounting Estimates. Factors that have contributed to the variation in loss development are primarily related to the extended period of time required to resolve professional liability claims and include the following:
The MPLHCPL legal environment deteriorated in the late 1990’s and severity began to increase at a greater pace than anticipated in our rates and reserve estimates. We addressed the adverse severity trends through increased rates, stricter underwriting and modifications to claims handling procedures. The expectation of increased claim severity was also considered in establishing our initial reserves for subsequent years.
These adverse severity trends later moderated with that moderation becoming more pronounced beginning in 2009. We have been cautious in giving full recognition to indications that the pace of severity increase has slowed, but have given measured recognition of the improving trends in our reserve estimates, as discussed more fully under “Critical Accounting Estimates—Reserve for Losses and Loss Adjustment Expenses (reserve for losses or reserve).” The favorable development has beenwas most pronounced for years 2004 to 2008, sinceas the initial reserves for these accident years were established prior to substantial indication that severity trends were moderating. We give stronger recognition to a lower severity trend as time elapses and the percentage of closed claims increases.
A general decline in claim frequency has also been a contributor to favorable loss development. A significant portion of our policies through 2003 were issued on an occurrence basis, and a smaller portion of our ongoing business results from the issuance of extended reporting endorsements which hashave occurrence-like exposure. As claim frequency declined, the number of reported claims related to these coverages was less than originally expected.

(1) Includes a net reserve reduction of $3.3 million for 2013 due to the re-estimation of reserves acquired in a 2012 business combination.
(2) Includes prior year paid losses of 33.4 million for 2013 attributable to reserves acquired in a business combination completed in 2013.
At December 31, 20122013 our gross reserve for losses included case reserves of approximately $1.1 billion and IBNR reserves of approximately $0.9 billion. Our consolidated gross reserve for losses on a GAAP basis exceeds the combined gross reserves of our insurance subsidiaries on a statutory basis by approximately $0.1 billion, which is principally due to the portion of the GAAP reserve for losses that is 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 who meets certain qualifications.

Reinsurance
We use insurance and reinsurance (collectively, “reinsurance”) to provide capacity to write larger limits of liability, to provide reimbursement for losses incurred under the higher limit coverages we offer, and to provide protection against losses in excess of policy limits, and to stabilize underwriting results in years in which higher losses occur.limits. 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 pay.
We have a number of reinsurance arrangements in place. We generally reinsure professional liability risks under annual treaties (our primary reinsurance arrangements) 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. Historically, the professional liability per claim retention level has varied between 90% and 100% of the first $1 million and between 0% and 5% of claims exceeding those levels depending on the coverage year and the state in

which business was written. Large professional liability risks that are above the limits of our basic reinsurance treaties are reinsured on a facultative basis, whereby the reinsurer agrees to insure a particular risk up to a designated limit. We also have in place a number of fronting and quota share arrangements that apply to certain groups of HCPL policies, generally those associated with a group of affiliated insureds or with a large practice group or facility. Gross and net written premium associated with such arrangements approximated $37.5 million and $20.2 million, respectively, during the year ended December 31, 2013. Medical technology and life sciences products coverages are separately reinsured, generally with 100% retention on the first $1 million of coverage and between 5% and 33% of coverage exceeding those levels, with additional loss participation if specified limits are exceeded. When we complete an acquisition, the acquired company's existing reinsurance agreements continue until the expiration date of the agreement, typically less than a one year period, and reimbursement under the agreements continues until all of the claims covered by the agreements are resolved. The structure of these pre-existing arrangements typically reflects a lower retention level than our primary arrangements.
Our primary reinsurance agreements are negotiated and renewed annually at October 1. There was no significant change in the cost or structure of the agreements renewed on October 1, 2012, other than we increased the upper limit of our coverage from $16 million to $26 million. The pricing structure2013.
We make a determination of the additional coverage is consistent with prior pricing for excess coverage.
Ouramount of insurance risk retention level is dependentwe choose to retain based upon numerous factors, including our risk tolerance and the capital we have to support it, the price and availability of reinsurance, volume of business, level of experience with a particular set of claims and our analysis of the potential underwriting results. We purchase reinsurance from a number of companies to mitigate concentrations of credit risk. We utilize a reinsurance brokersbroker to assist us in the placement of our reinsurance coverageprogram and in the analysis of the credit quality of our reinsurers. We base our reinsurance buying decisions onThe determination of which reinsurers we choose to do business with is based upon an evaluation of thetheir then-current financial strength, rating and stability of prospective reinsurers.stability. 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.
The following table identifies those reinsurers for which our recoverables for both paid and unpaid claims (net of amounts due to the reinsurer) and our prepaid balances are aggregately $10$20 million or more as of December 31, 20122013:

Taxes
In December 2012 we received a Notice of Proposed Adjustment (NOPA) from the IRS which disallows a substantial portion of the loss and loss adjustment expense deductions taken for the 2009 and 2010 fiscal years and would thereby increase our current tax liability by approximately $130 million. In January 2013 we submitted a comprehensive written protest of the NOPA to the IRS Office of Appeals regarding certain issues within the NOPA, all of which related to the timing of deductions. During the fourth quarter of 2013, we reached a tentative settlement of all contested Federal income tax issues for the related tax years which will result in no additional tax liability for us. Other non-contested issues addressed by the NOPA are expected to result in a net federal income tax refund, exclusive of statutory interest, of approximately $9.6 million. We believe that our loss and loss adjustment expense deduction was computed in a manner consistent with tax law, our past practices, and the practicestentative terms of other liability insurers, and we have begun the process of contesting the IRS position. The proposed adjustment represents a temporary timing difference and impacts the timing of deductions, rather than their allowance, and would shift tax from deferred to current tax expense but would not increase total tax expense. Additional tax payments that might be made as a result of the NOPA would come out of our cash and investments and could impact future investment earnings, but, except for interest on past-due taxes, if any, will not change recorded tax expense. We have considered this matter in establishing our liability for uncertain tax matters. We do not know when a final resolution will be reachedsettlement with the IRS or the extent, if any, to which we mightwill be required to accelerate our tax payments or the amount of interest, if any, we might be required to pay.documented and finalized during 2014. In January 2013 we made a $20$20.6 million protective tax payment to the IRS in order to reduce potential interest assessments shouldassessments. We expect the IRS positionprotective payment to also be fully or partially sustained.refunded once the settlement is finalized.

Litigation
We are involved in various legal actions related to insurance policies and claims handling including, but not limited to, claims asserted against us by policyholders. These types of legal actions arise in the ordinary course of business and, in accordance with GAAP for insurance entities, are generally considered as a part of our loss reserving process, which is described in detail under “Critical Accounting Estimates – Reserve for Losses and Loss Adjustment Expenses (reserve for losses or reserve).” We also have other direct actions against the company unrelated to our claims activity which we evaluate and account for as a part of our other liabilities. For these corporate legal actions, we evaluate each case separately and establish what we believe is an appropriate reserve based on GAAP guidance related to contingent liabilities. As of December 31, 2013 there were no significant reserves established for corporate legal actions.

A detailed listing of our investment holdings as of December 31, 20122013 is presented in an Investor Supplement we make available in the Investor Relations section of our website, www.proassurance.com, or directly at www.proassurance.com/investorrelations/supplemental.aspx.
We manage our investments to ensure that we will have sufficient liquidity to meet our obligations, taking into consideration the timing of cash flows from our investments, including interest payments, dividends and principal payments, as well as the expected cash flows to be generated by our operations. In addition to the interest and dividends we will receive, we anticipate that between $40 million and $7060 million of our investments will mature (or be paid down) each quarter of the next year and become available, if needed, to meet our cash flow requirements. The primary outflow of cash at our insurance subsidiaries is related to paid losses and operating costs, including income taxes. The payment of individual claims cannot be predicted with certainty; therefore, we rely upon the history of paid claims in estimating the timing of future claims payments. To the extent that we may have an unanticipated shortfall in cash we may either liquidate securities or borrow funds under existing borrowing arrangements through our credit facility and the FHLB system. In December 2012 we elected to partially fund our acquisition of Medmarc by borrowing $125$125.0 million from our existing credit facility on a fully secured basis as this allowed us to continue to hold rather than liquidate certain higher yielding securities. At December 31, 2012,We repaid the borrowing during September 2013. Currently, $25150 million of the credit facility remainsis available for use. Given the relatively short duration of our investments, we do not foresee a shortfall that would require us to meet operating cash needs through additional borrowings. Additional information regarding the credit facility is detailed in Note 10 of the Notes to Consolidated Financial Statements.
Our investment portfolio continues to be primarily composed of high quality fixed income securities with approximately 93% of our fixed maturities being investment grade securities as determined by national rating agencies. The weighted average effective duration of our fixed maturity securities at December 31, 20122013 was 3.83.9 years; the weighted average effective duration of our fixed maturity securities combined with our short-term securities was 3.73.6 years. Net unrealized gains related to our fixed income securities decreased approximately $131.9 million during 2013. As interest rates have improved, the value of our fixed income securities has declined.
The carrying value of our tax credit partnerships at December 31, 20122013, 20112012 and 20102011 was approximately $87.3142.2 million, $86.887.3 million and $60.286.8 million, respectively. The carryingCarrying value reflectedreflects our total commitments (both funded and unfunded) to the partnerships, less amortization, since our initial investment. These investments are comprised of separate limited partner interests designed to generate investment returns by providing tax benefits to investors in the form of project operating losses and tax credits. The related properties are principally low income housing properties. We fund these investments based on funding schedules maintained by the partnerships. During 20122013, 20112012 and 20102011 we funded approximately $35.763.5 million, $29.235.7 million and $13.629.2 million, respectively. Approximately $20.522.4 million, $49.320.5 million and $46.849.3 million of our total commitments to the tax credit partnerships had not yet been funded as of December 31, 20122013, 20112012 and 20102011, respectively.
During 20122013, 20112012 and 20102011, we increasedthe total carrying value of our investments in LPs/LLCs that are investment fund interests rather than tax credit partnership interests byLPs/LLCs was approximately $119.3 million, $58.8 million and $56.6 million, respectively, all of which has been funded. The 2013 carrying value includes $18.510.5 million related to our portion of an LP's accumulated earnings that were recorded as a result of a change from the cost to equity method. During 2013, $4.7 million2012 and $15.4 million2011, we funded investment LP/LLCs, net of capital returned, in the amount of $37.8 million, $18.5 million, and $4.7 million, respectively. As of December 31, 20122013, we had unfundedtotal active commitments to these LPs/investment fund LP/LLCs of approximately $203.0 million, of which $81.9140.9 million. is unfunded. The remainingunfunded commitments will be paid over a period of approximately 5 years as requested by the fund managers.
European Debt Exposure
We have no direct European sovereign debt exposure. We have indirect exposure through our investments in debt securities and through our reinsurance receivables. Issuers of our debt or equity securities and our reinsurers may hold European sovereign debt or have counterparty exposure to European banks or European corporations or may have a reliance on Eurocurrency denominated business. Should Europe suffer a severe recession or the Euro-zone or Eurocurrency fail, issuers may suffer credit or profitability losses or may experience a credit downgrade by rating agencies.

Our debt securities at December 31, 20122013 included investments of $121.9124.7 million (3% of our total investments) where the issuer is domiciled in Europe or the underlying revenue stream supporting the security is European. Of our European issuers, we believe those in the financial sector are most likely to suffer loss in the event of a European economic crisis.

Our reinsurers typically operate globally and have large investment portfolios which may be linked directly or indirectly to the European economy. As of December 31, 20122013, two of our largest reinsurers were domiciled in Europe; our net receivables with these reinsurers totaled approximately $5345 million. Net amounts due from reinsurers approximated $164.0237.9 million at December 31, 20122013.

Net realized investment gains in 20122013 were approximately $22.939.0 million higher than in 20112012. The improvement was principally attributable to an increase in our average equity trading portfolio but also reflected additional gains from sales of fixed maturity securitiesinvestment and lower impairment losses in 2012.
Other income decreased byimproved stock market yields. Impairments were nominal for 2013 and were $6.51.8 million infor 2012. The decrease is primarily attributable to $4.9 million of other income in 2011 that resulted from the confidential settlement of litigation with a service provider.

We reduced net losses2013 as compared to 2012 by $272.049.3 million and $325.9 million in 2012 and 2011, respectively, as a result of our review of our estimate of net losses incurred for prior accident years.
Underwriting, policy acquisition and operating expenses decreased by $0.8 million or 0.6% in 2012 as compared to 2011, which reflected lower costs associated with the operations we acquired from APS, offset by additional expense due to recently closed merger transactions, higher compensation costs and the effect of adopting new FASB guidance regarding policy acquisition costs.

Premiums Written
Changes in our premium volume are driven by four primary factors: (1) the amount of new business generated both as a result of acquisitions and through our existing books of business, (2) our retention of existing business, (2)(3) the premium charged for business that is renewed, which is affected by rates charged and by the amount and type of coverage an insured chooses to purchase, (3)and (4) the timing of premium written through multi-period policies, and (4)policies.

number of factors. We may lose insureds to competitors or to alternative insurance mechanisms such as risk retention groups or self-insurance entities (often when physicians join hospitals or large group practices) or due to pricing or other issues. We may choose not to renew an insured as a result of our underwriting evaluation. Insureds may also terminate coverage because they have left the practice of medicine for various reasons, principally for retirement but also for personal reasons or due to disability or death.

Our charged rates includeThe pricing of our business includes the effects of filed rates, surcharges and discounts. Despite competitive pressures, weWe continue to base our ratespricing on expected losses, as indicated by our historical loss data and available industry loss data. We are committed to a rate structure that will allow us to fulfill our obligations to our insureds, while generating competitive returns for our shareholders.
NewPhysician policies were our greatest source of premium revenues in both 2013 and 2012. In addition to the effects of retention and renewal pricing discussed above, our 2013 twelve month term physician premium volume reflected the following:
The acquisition of IND contributed approximately $10.5 million of physician premium to 2013.
In addition to premium contributed by IND, we wrote new physician business written in 2012 wasof approximately $918 million in 2013.
We offer twenty-four month term policies to our physician insureds in one selected jurisdiction. The premium associated with both years is included in written premium in the period the policy is written; comparison of gross written premium between successive years reflects volume differences that have no effect on earned premium. Thus, twenty-four month term policies subject to renewal in 2013 were previously written in 2011 rather than in 2012, as is the case for our twelve-month term policies. There was no significant volume change associated with twenty-four month policies during 2013.
Our non-physicianother healthcare providers are primarily dentists, chiropractors and allied health professionals. The 2012decline decline in premium volume for these coverages during 2013was primarily attributable to allied health professionals.the 2012 discontinuation of a program that offered coverage to optometrists.

Ceded premiums for our higher limit coverages are almost fully reinsured2013 and were estimated to be lower for the 2012 accident year than for the 2011 accident year. As a result, our estimate of ceded premium owed under our primary reinsurance agreements for the current accident year was lower in 2012.
Many years may elapse before all losses recoverable under a reinsurance agreement are known. In the intervening periods, amounts owed are estimated. Premiums ceded for the current period includes both our estimate of premiums owed under reinsurance agreements of the current period and changes to our previous estimate of premiums owed under reinsurance agreements of prior periods. In both 2012 and 2011, we reduced our estimates of prior accident year gross losses within our reinsured layers of coverage,compare as well as the related reinsurance recoveries and premiums ceded.follows:
(1)
As discussed previously, the premium that we cede under our reinsurance arrangements is determined, in part, by the losses ceded under these arrangements. Ceded premiums decreased due to lower premiums in 2013, and beginning with the second quarter of 2012, we projected (estimated) lower losses for our ceded coverages and reduced our estimate of the associated ceded premium for the current accident year. The year ended December 31, 2013 reflected those lower projections for the full period in 2013 as compared to two quarters in 2012.
(2)
We have secondary arrangements with certain large healthcare groups that include quota share, fronting and other risk sharing arrangements. Growth in these arrangements increased ceded premium in 2013 as compared to 2012. These arrangements are primarily comprised of the following:
We share the risk of loss for policies written or renewed under the Ascension Health (Ascension) Certitude program with an Ascension affiliate under a quota share agreement. Growtharrangement.
We have entered into fronting arrangements with certain large healthcare groups. Under the arrangements we provide specified underwriting, claims and risk management services but cede a large portion of the risk of the coverages provided back to the group or affiliates of the group. Volume under such arrangements can vary between periods.
During 2013, we entered into quota share arrangements under which we share the risk of loss with captive insurers affiliated with one of our agents.
(3)
Given the length of time that it takes to resolve our claims, many years may elapse before all losses recoverable under a reinsurance agreement are known. As a part of the process of estimating our loss reserves we also make estimates regarding the amounts recoverable under our reinsurance agreements. As previously discussed, the amounts ultimately owed under our reinsurance agreements are subject to the losses ceded under the agreements. In both 2013 and 2012, on a net basis, we reduced our estimate of expected losses and associated recoveries for prior year ceded losses, as well as our estimate of ceded premiums owed to reinsurers. The reductions were substantially less in 2013 than in 2012. The net reduction for 2013 includes an offsetting increase of $1.6 million that was attributable to loss reserves acquired in business combinations. In 2012 we also revised the expected amount receivable under certain older reinsurance agreements for which there were limited remaining open items. Changes to estimates of premiums ceded related to prior accident years are fully earned in the period the change in estimates occur.
Ceded Premiums Ratio
As shown in the program increasedtable below, our ceded premium ratio was significantly affected in both 2013 and 2012 by revisions to our estimate of premiums owed to reinsurers related to coverages provided in prior accident years.

* Effect shown for 2013 is net of an increase to the ratio of approximately 0.3 percentage points attributable to business combinations.
The increase in the ceded premium ratio, current accident year, for 2013 as compared to 20112012. is attributable to the following:
During 2011, we commuted (terminated) certain of our reinsurance agreements with Colisee Re (formerly AXA Reassurance S.A.) in return for approximately $4.3 million in cash. The commutation reduced Ceded Premium, on both a written and an earned basis, by $5.6 million and reduced Reinsurance Recoveries by approximately $4.0 million.
We reinsure most of our MPL coverages under a single reinsurance agreement that is renewed annually (referred to as our primary reinsurance agreement). Professional liability offered to dentists, allied health professionals, certain smaller facilities as well as higher limit MPL coverages were reinsured under separately negotiated contracts until October 1, 2012, but thereafter are covered by our primary reinsurance agreement. Amounts due to reinsurers under these separate contracts are included along with legal professional liability in the preceding table as "Other premiums ceded."

Net premiums earned consist of gross premiums earned less the portion of earned premiums that we cede to our reinsurers for their assumption of a portion of our losses. Because premiums are generally earned pro rata over the entire policy period, fluctuations in premiums earned tend to lag those of premiums written. Generally, our policies carry a term of one year, but as discussed above, we renew certain policies with a two-yeartwenty-four month term, and certain of our medical technology and life sciences products liability policies carry a multi-year term. Tail coverage premiums are generally 100% earned in the period written because the policies insure only incidents that occurred in prior periods and are not cancellable. Additionally, ceded premium changes due to commutations or changes to estimates of premiums owed under reinsurance agreements are fully earned in the period of change.
PremiumsGross premiums earned were lower in 20122013, as compared to reflected additional premiums contributed by acquisitions of approximately 2011$53.9 million, principally due to offset by the pro-rata effect of lower non-tail physician premiums written by our other subsidiaries during the preceding twelve months, partially offset by higherand a decline in tail premiums written and earned inpremium of 2012$8.9 million. Our 2013 gross premiums earned includes approximately $25.1 million in gross premiums earned associated with Medmarc and IND policies written prior to our acquisition of these operations. We expect Medmarc and IND policies written pre-acquisition to contribute gross premiums earned of approximately $3.0 million in 2014 and beyond.

Net Investment Income, Equity in Earnings (Loss) of Unconsolidated Subsidiaries, Net Realized Investment Gains (Losses)
Net Investment Income
Net investment income is primarily derived from the income earned by our fixed maturity securities and also includes income from our short-term and cash equivalent investments, dividend income from equity securities, earnings from other investments and increases in the cash surrender value of business owned life insurance contracts. Investment fees and expenses are deducted from investment income.

Fixed Maturities
As compared to 2011, earningsThe decrease in our income from fixed maturity investments declinedsecurities was primarily due to both lower average yields and average investment balances (exclusive of acquisitions) as compared to 2012. Although we added fixed securities valued at $314 million to our portfolio in 2012. Our2013 as a result of the Medmarc and IND mergers, we reduced the size of our fixed portfolio in 2013 in order to repay debt, pay dividends and invest in other asset classes. On an overall basis our average investment in fixed maturities decreased bysecurities was approximately 3% lower in 20122013. In 2012 a portion of the proceeds from sales and maturities of our fixed maturities were not reinvested but instead were utilized for other corporate purposes which included payment of shareholder dividends, repayment of debt and partial funding of acquisitions. Yields as compared to 2012.
Average yields for our fixed maturity portfolio were generally lower in 20122013. As, as shown in the table below.

Yields on fixed maturity securities matured,acquired in the Medmarc and IND transactions were paid down or sold, in order to maintain the asset quality and duration oflower than our portfolio, most funds reinvested were at lower rates, although we did add certain higher yielding fixed maturities to our portfolioaverage yield in 2012, as a means of improving overall yields.which reduced our 2013 average consolidated tax equivalent yield by approximately 15 basis points. Yields for 20122013 also reflected lower income from Treasury Inflation-Protected Securities of $1.0 million. The remaining decline in yield is primarily attributable to market conditions. Throughout 2012 and to a declining degree in 2013, in order to maintain the quality and duration of our portfolio, we have reinvested maturities, paydowns and proceeds from sales in our fixed income portfolio at yields that were lower than the average yield on our portfolio.
Equities
Income from our equity portfolio $1.0 millionincreased in 2013 as compared to 2012 due to average investment balances that were approximately 59% higher in 2013. Average yields forGiven the challenge in finding compelling returns in the fixed income portfolio as discussed above and the sensitivity of the value of the fixed income portfolio to rising interest rates, we have increased our fixed maturity securities during the years ended December 31, 2012allocation to dividend yielding equities and 2011 were as follows:other non-fixed income investments.

EquitiesShort-term Investments and Other Invested Assets
IncomeThe increased income from our equity portfolio increasedshort-term investments and other invested assets in 2012 as compared to 2011 and primarily reflects higher average investment balances in 2012. A portion of the increased investment is attributable to2013 principally reflected distributions received from an interest in a privatean LP that we account for using the cost method. No distributions were received from this investment LLC, classified as a part of Other investments during 2011, that was converted into publicly traded equity securities during 2012. The in 2012 income decline for Other invested assets was principally attributable to this conversion..

We hold interests in certain LPs that generate earnings from trading portfolios.portfolios, secured debt, and private equity investments. The performanceimproved results for 2013 principally reflect earnings recognized as a result of a change of an LP from the cost method to the equity method as well as higher earnings from a private equity LP. When there is a change from the cost to the equity method, GAAP requires retroactive recording of accumulated earnings since the origination of the LPs isinvestment. As the amounts are not material in the current period or any of the prior periods affected, byprior period financial statements have not been restated. Earnings included our portion of the volatilityLP’s accumulated earnings from the date of equity and credit markets.initial investment, which totaled $10.5 million, $8.4 million of which was related to prior periods.
Our business LLC interest iswas a non-controlling interest in ana startup entity, that began active businesswhich produced operating losses in 2011.2012. We recognize quarterly our allocable portion of the operating results reported by the LLC. The entity was slower to produce positive operating returns than initially anticipated and losses recognized in 2012 have reduced the carrying amount ofdissolved our interest to zero.in the entity during 2013.
Our tax credit investments are designed to generate investment returns by providing tax benefits to fund investors in the form of tax credits and tax-deductible project operating losses. We account for our tax credit investments on the equity method and record amortization of our investment each period based on our allocable portion of the projected operating losses of the underlying properties. Amortization is adjusted periodically as actual operating results of the underlying properties become available. The increase in tax credit partnership amortization during 2013 reflects an overall increase in our investment in these partnerships, the increasing maturity of the underlying projects, and reductions to amortization during 2012 that were attributable to the re-estimation of inception-to-date amortization of certain partnership interests.
The tax credits. Ourbenefits received from our tax credit partnerships, which are not reflected in our investment results above, reduced our tax expenses by approximately $10.0 million during the year ended December 31,in 2013 and 2012, while we recognized $6.4 million as follows:

Non-GAAP Financial Measure – Tax Equivalent Investment Result
We believe that to fully understand our investment returns it is important to consider the current tax benefits associated with certain investments; therefore, weinvestments as the tax benefit received represents a portion of the return provided by our tax-exempt bonds, BOLI, common and preferred stocks, and tax credit partnership investments (our tax-preferred investments). We impute a pro formapro-forma tax-equivalent investment result by adjusting the current tax benefit intoestimating the amount of investmentfully-taxable income a taxable investment would needneeded to produce to fairly compare to an investment with preferential tax treatment.achieve the same after-tax result as is currently provided by our tax-preferred investments. We believe this better reflects the economics ofbehind our decision to invest in certain asset classes that are either taxed at lower rates and/or result in reductions to our current federal income tax expense. Our pro forma tax-equivalent investment result is shown in the table that follows as is a reconciliation of our tax equivalent result to our GAAP net investment result.

For more information, see Note 3 and Note 10 of the Notes to Consolidated Financial Statements.
Other Income
Other Income is comprised primarily of commission and fee income from our agency operations, other fee revenues, rental income and other miscellaneous revenues. The revenue is not a principal source of income and often varies among periods. The decrease in 2012 as compared to 2011 primarily reflected other income of $4.9 million recognized in 2011 related to a confidential settlement of litigation with a service provider and a gain of approximately $0.8 million recognized on the sale of a building in 2011.
Losses and Loss Adjustment Expenses
The determination of calendar year losses involves the actuarial evaluation of incurred losses for the current accident year and the actuarial re-evaluation of incurred losses for prior accident years, including an evaluation of the reserve amounts required for losses in excess of policy limits.
Accident year refers to the accounting period in which the insured event becomes a liability of the insurer. For claims-made policies, which represent over 90% of the Company’s business, the insured event generally becomes a liability when the event is first reported to the insurer. For occurrence policies the insured event becomes a liability when the event takes place. We believe that measuring losses on an accident year basis is the best measure of the underlying profitability of the premiums earned in that period, since it associates policy premiums earned with the estimate of the losses incurred related to those policy premiums.

The 2012 decrease in our current accident year net loss ratio reflects the following:
In 2012 we decreased our loss reserves related to death, disability and retirement (DDR) coverage endorsements provided to our insureds while in 2011 we increased loss reserves for this coverage. The reserve for DDR is actuarially estimated and is affected by changes in the number of insureds expected to benefit from the coverage endorsement.
Net earned premium in both 2012 and 2011 was increased by reductions to amounts owed under reinsurance agreements (see "Net Premiums Earned"). The reductions had a greater effect on the net loss ratio in 2012.
A commutation recorded in 2011 increased the 2011 net loss ratio; no commutation was recorded in 2012.
More of our net earned premium was from tail coverages in 2012. This increases our average net loss ratio because we expect higher losses for tail coverages than for our other professional liability coverages.
(1)Net losses as specified divided by net premiums earned.
(2)Reductions to premiums owed under reinsurance agreements for prior accident years increased net earned premiums (the denominator of the current accident year ratio) in both 2013 and 2012. The net increase to the ratio in 2013 reflects an offset of 0.3 percentage points that is attributable to loss reserves acquired in business combinations. See the discussion under the heading “Ceded Premiums Written” for additional information.
(3)In addition to the effect of ceded premiums associated with prior accident years, the loss ratio for the current period reflects an increase due to higher unallocated loss adjustment expenses in 2013, the effect of which was offset by decreases to the ratio attributable to a lower amount of tail premium in 2013, a greater benefit from current accident year reinsurance in 2013, and lower average loss ratios for the business acquired from Medmarc and IND. The amount of tail premium affects the average ratio because we generally expect higher losses from tail coverages.
We recognized favorable loss development related to prior accident yearspreviously established reserves, on a gross basis, of$248.5 million in 2013 and $321.5 million in 2012. On a net basis, we recognized favorable development of $222.7 million in 2013 and $272.0 million forin 2012. The net basis reflects the year ended December 31, 2012 and $325.9 million for the year ended December 31, 2011.favorable development recognized with respect to our ceded coverage layers. A detailed discussion of factors influencing our recognition of loss development recognized is included in the Critical Accounting Estimates section of Item 7, under the caption “Reserve"Reserve for Losses and Loss Adjustment Expenses." Information provided includes the amount of development recognized by accident year and the factors considered and judgments made to determine the amount of development recognized.
Assumptions used in establishing our reserve are regularly reviewed and updated by management as new data becomes available. Any adjustments necessary are reflected in the 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, as was the case in both 20122013 and 20112012.
Recoveries
We recognized favorable prior accident year loss development of approximately $49.4 million in 2012 and $39.9 million in 2011 related to our reinsured coverage layers (generally, losses exceeding $1 million) and recognized offsetting reductions to loss recoveries of $49.4 million in 2012 and $39.9 million in 2011. Because the reductions exceed other recoveries during each year, recoveries increased rather than decreased net losses for the years ended December 31, 2012 and 2011.
We similarly reduced our estimates of the premium due to reinsurers by $34.3 million and $30.6 million in 2012 and 2011, respectively, because the premium due to reinsurers is based in part on amounts recovered.

We incurred expenses related to the mergers of INDyears ended December 31, 2013 and Medmarc of approximately $1.5 million in 2012. We anticipate additional expenses directly related to our merger with Medmarc of approximately $0.8 million, most of which will be incurred in the first quarter of 2013.
As discussed in Notes 1 and 7 of the Notes to Consolidated Financial Statements, we adopted, on a prospective basis, new FASB guidance related to the deferral of policy acquisition costs. The new guidance affects the timing, but not the amount of acquisition costs ultimately expensed, as the decrease in the expense deferral reduces amortization of policy acquisition costs by the same amount, recognized over the term of the associated successful policies. Our 2012 expenses reflect a net increase of approximately $1.9 million in 2012 due to adoption of the new guidance, as we expensed approximately $4.2 million of policy acquisition costs that under prior guidance would have been deferred to later periods but also recognized amortization expense that was approximately $2.3 million lower than would have been recognized under previous guidance.
Exclusive of the effect of the new FASB guidance, amortization of deferred policy acquisition costs was $0.3 million lower in 2012 than in 2011. While amortization was lower in 2012 consistent with the decline in net premiums earned, amortization in 2011 was reduced by approximately $1.5 million related to the acquisition of APS in November 2010. Due to the application of GAAP purchase accounting rules, no asset for deferred policy acquisition costs was recognized as a part of the purchase price allocation of APS; consequently, amortization of deferred policy acquisition costs in 2011 was reduced.
On a sporadic basis our expenses are reduced by recoveries related to the settlement of litigation. Recoveries in 2012 were approximately $0.5 million lower (and thus expenses on a net basis were higher) than in 2011.
Costs associated with the operations acquired from APS, primarily compensation costs, were approximately $3.7 million lower in 2012 as compared to 2011.
Higher stock compensation and bonus costs in 2012 as compared to 2011 as well as additional costs incurred related to the enhancement of our customer service capabilities increased our 2012 expenses by approximately $5.0 million. We relocated a number of positions in order to create centralized customer service centers. Relocation benefits were provided to affected employees as well as termination benefits for employees unable to relocate. Expenses of $1.6 million related to a deferred compensation agreement with a former senior executive increased our expenses in 2011; there were no comparable expenses in 2012.
Various other operating costs were collectively lower by approximately $3.2 million in 2012.

Amortization of deferred policy acquisition costs reflects a reduction in 2013 attributable to lower premium volume and a reduction attributable to the adoption of new accounting guidance at the beginning of 2012. The effect of lower premium volume was somewhat offset in 2013 by underwriting compensation costs which were higher in 2013 than in 2012.(2.6)

The impact of purchase accounting related to deferred policy acquisition costs reduced the reported expenses by approximately $4.4 million in 2013.
(2)As discussed previously in ProAssurance Overview, we acquired Eastern Insurance Holding, Inc. effective January 1, 2014. We anticipate additional expenses directly related to our merger with Eastern of approximately $3.3 million, of which $1.3 million is expected to be incurred during the first six months of 2014. The remainder consists of retention and severance costs that we expect to incur fairly evenly over the next three years.
(3)Also, as discussed in ProAssurance Overview, we completed the process of becoming a corporate member of Lloyd's of London late in 2013. We do not expect to incur significant expenses in 2014 related to the start-up of Syndicate 1729; additional costs will primarily be incurred by Syndicate 1729.

Agency Expenses
We maintain limited agency operations that both generate premium revenues for our insurance subsidiaries and earn external commission and service fee revenues. Agency operations that are associated with the generation of premium revenues by our insurance subsidiaries are included in insurance operation expenses in the above table. Expenses of agency operations that are directly associated with external commission and service fee revenues are included in agency expenses in the above table. Agency expenses for 2011 included non-recurring expenses associated with the dissolution of certain agency operations.

Interest Expense
Interest expense declinedincreased during 20122013 as compared to 20112012. The increase reflects higher average outstanding debt in 2013 but lower average rates. Our weighted average outstanding debt approximated $119 million for 2013, primarily because we repaidwhile our average outstanding debt duringapproximated $29 million for 2012, as discussed in Liquidity and Capital Resources and Financial Condition. .

Revenues
Net premiums earned increaseddecreased during 20112012 by approximately $46.3$14.8 million or 8.9%, including an increase of approximately $53.0 million attributable to the business acquired from APS. Our results also reflect2.6%. The decrease principally reflects the effects of a competitive market place, and rate reductions that reflect improved loss trends.but also reflected a net decrease of approximately $1.9 million related to ceded premium owed to reinsurers for prior year coverages.
Our 2011 net investment result (which includes both net investment income and earnings from unconsolidated subsidiaries) decreased by $15.8$2.6 million or 10.7%2.0%. Net investment income decreased $5.4during 2012, primarily due to lower yields on our fixed income portfolio and lower average fixed income investment balances. Approximately $0.8 million and earnings from unconsolidated subsidiaries decreased $10.4 million.of the decrease is due to increased amortization of tax credit investments in 2012.
Net realized investment gains in 2012 were approximately $22.9 million higher than in 2011. The improvement was principally attributable to our equity trading portfolio, but also reflected additional gains from sales of fixed maturity securities and lower impairment losses in 2012.
Other income decreased $11.3by $6.5 million in 2011.2012. The decrease is primarily dueattributable to lower gains on securities sales mitigated by lower impairment losses.
Other$4.9 million of other income increased by $5.6 million during 2011. The increase is primarily due to ain 2011 that resulted from the confidential settlement received during the third quarter of 2011 related to litigation with a service provider.
Expenses
Current accident year net losses increaseddecreased by $33.1$36.2 million or 7.3% during 2011, including an increase of approximately $44.5 million7.4% in 2012 as compared to 2011. The decline was principally attributable to a reduction in the business acquired from APS.number of insured risks, but also reflected lower expected losses for our death, disability and retirement coverages, and the effect of a commutation recorded in 2011. We reduced net losses by $272.0 million and $325.9 million in 2012 and 2011, and by $234.0 million in 2010respectively, as a result of our review of our estimate of net losses incurred for prior accident years.
Underwriting, policy acquisition and operating expenses increaseddecreased by $0.8 million or 0.6% in 20112012 as compared to 20102011, which reflected lower costs associated with the operations we acquired from APS, offset by $1.4 million or 1.1%. Theadditional expense due to recently closed merger transactions, higher compensation costs and the effect of adopting new FASB guidance regarding policy acquisition costs.
We recognized losses of APS added expenses of $8.0$2.2 million in 2011. Exclusive2012 related to the repayment of APS, expenses decreased $6.6 million primarily due to lower amortization of deferred policy acquisition costs and a 2010 expense increase from the termination of a captive insurance agreement that did not recur in 2011.2019 Note Payable which was carried at fair value.
Ratios
Our current accident year net loss ratio decreased in 2011 by 13.94.2 percentage points in 2012 due to changes in the mix of insured risks. Our calendar year net loss ratio was 32.7% for 2012 as we experienced ancompared to 28.7% for 2011, with the increase in prior yearreflecting the emergence of a smaller amount of favorable development in 2011 as compared to 2010. Approximately 12.5 percentage points of the decline relates to the increase in prior year favorable development.2012.
Our 2011 underwriting expense ratio decreased 1.6increased 0.6 percentage points in 2012, principally reflecting athe effect of lower ratio associated with the business acquired from APS and an increase in net premiums earned that is related to favorable development of prior year loss reserves.in 2012.

Due to the size of our Shareholders’ Equity (approximately $2.2$2.3 billion at December 31, 2011)2012), the growth rate of our book value per share may slow.

Non-GAAP Financial Measures
Operating income is a non-GAAP financial measure that is widely used to evaluate the performance of insurance entities. Operating income excludes the after-tax effects of net realized investment gains or losses, guaranty fund assessments, debt retirement gain or loss and in 2011, the effectseffect of certain confidential settlements that do not reflect normal operating results. We believe operating income presents a useful view of the performance of our insurance operations, but should be considered in conjunction with net income computed in accordance with GAAP.

Premiums Written
Changes in our premium volume are driven by four primary factors: (1) the amount of new business we generate, including business that comes to PRA as a result of acquisitions, (2) the timing of premium written for business generated by multi-period policies, (3) our retention of existing business, and (4)(2) the premium charged for business that is renewed, which is affected both by rates charged and by the amount and type of coverage an insured chooses to purchase.purchase, (3) the timing of premium written through multi-period policies, and (4) the amount of new business we generate. The professional liability market remains competitive with some competitors choosing to compete primarily on price.

Our retention rate for our standard physician business including business acquired from APS, is 89%was 90% for 2011,2012, as compared to 90%89% for 2010.2011. We calculate our retention rate as retained premium divided by all premium subject to renewal. Retention rates are affected by a number of factors. We may lose insureds to competitors or to alternative insurance mechanisms such as risk retention groups or self-insurance mechanismsentities (often when physicians join hospital-based practice groups)hospitals or large group practices) or due to pricing or other issues. We may choose not to renew an insured as a result of our underwriting evaluation. Insureds may also terminate coverage because they have left the practice of medicine for various reasons, principally for retirement but also for personal reasons or due to disability or other personal reasons.death.
Charged rates for our renewed physician business including business acquired from APS, averaged 1% lowerhigher than the expiring premiums during 2011.2012. Our charged rates include the effects of filed rates, surcharges and discounts. Despite competitive pressures, we continue to base our rates on expected losses, as indicated by our historical loss data and available industry loss data. We are committed to a rate structure that will allow us to fulfill our obligations to our insureds, while generating competitive returns for our shareholders.

Non-continuingOur non-continuing premiums consist of premiums derived from optometry coverages discontinued in early 2012 and certain miscellaneous liability coverages which were discontinued in 2010 but that continued to produce small amounts of written premium in 2011.
Tail Coverage Premiums2011 and 2012.
We offer extended reporting endorsement or “tail” coverage to insureds that are discontinuing their claims-made coverage with us.us, and we also periodically offer “tail” coverage through custom policies. The amount of tail coverage premium written and earned can vary widely from period to period. A large portion of the increase in tail premium in 2012 was attributable to a single custom policy issued to a hospital that terminated its self insurance arrangement.

Ceded premiums represent the amounts owed to our reinsurers for their assumption of a portion of our losses. The ultimate amount owed under certain of our reinsurance agreements is variable and is determined by the loss experience of the business ceded, subject to minimums and maximums. Losses incurred for our higher limit coverages are almost fully reinsured and were estimated to be lower for the 2012 accident year than for the 2011 accident year. As a result, our estimate of ceded premium owed under our primary reinsurance agreements for the current accident year was lower in 2012.
Many years may elapse before all losses recoverable under a reinsurance agreement are known. In the intervening periods, amounts owed are estimated. Premiums ceded for the current period includes both our estimate of premiums owed under reinsurance agreements of the current period and changes to our previous estimate of premiums owed under reinsurance agreements of prior periods. In both 2012 and 2011, we reduced our estimates of prior accident year gross losses within our reinsured layers of coverage, as well as the related reinsurance recoveries and premiums ceded.
We reinsure mostshare the risk of our MPL coveragesloss for policies written or renewed under a single reinsurance agreement that is typically renewed annually in October. There was no significant change in treaty terms between 2011 and 2010, and the 2011 decrease associated with this reinsurance is largely due to lower premium volume relative to reinsured coverages.
In 2011 we entered into a new business relationship with Ascension Health (Ascension). Our agreements Certitude program with an Ascension provide thataffiliate under a substantial portion of the initial policies written underquota share agreement. Growth in the program will be heavily reinsured by an Ascension affiliate. Gross premiums written associated with these policiesincreased ceded premium in 2011 is approximately $7.5 million.
The increase in ceded premiums written that is attributable2012 as compared to the APS acquisition primarily reflects eleven additional months of APS activity in 2011.
During 2011, we commuted (terminated) certain of our reinsurance agreements with Colisee Re (formerly AXA Reassurance S.A.) in return for approximately $4.3 million in cash. The commutation reduced Ceded Premium, on both a written and an earned basis, by $5.6 million and reduced Reinsurance Recoveries by approximately $4.0 million.
We reinsure most of our MPL coverages under a single reinsurance agreement that is renewed annually (referred to as our primary reinsurance agreement). Professional liability offered to dentists, allied health professionals, certain smaller facilities as well as higher limit MPL coverages were reinsured under separately negotiated contracts until October 1, 2012, but thereafter are covered by our primary reinsurance agreement. Amounts due to reinsurers under these separate contracts are included along with legal professional liability in the preceding table as "Other premiums ceded."

Ceded Premiums ceded in both 2011 and 2010 were reduced due to the re-estimation of reinsurance premiums incurred for prior accident years. Ratio
The amount of reinsurance premiums incurred for prior accident years is largely determined based on the losses expected to be recovered under our reinsurance agreements, subject to certain minimums and maximums specific to the reinsurance agreement being adjusted. In both 2011 and 2010, we reduced our estimates of prior accident year gross losses within our reinsured layers of coverage, as well as the related reinsurance recoveries and premiums ceded. The reductions were more pronounced in 2011. Approximately $1.0 millionprincipal components of the 2011 reduction is attributable to APS pre-acquisition reinsurance contracts.
The variationschange in ceded premiums written discussed above affect our ceded premiums ratio (ceded premiums written as a percentage of gross premiums written) as follows:are shown in the following table:

Re-estimation of prior accident year reinsurance premiums (including APS) (6.1%) (2.5%) (3.6)
Ceded premiums ratio, as reported 1.3% 5.2% (3.9)
The ceded premiums written ratio associated with the business acquired from APS is lower than the ratio for our other business. In recent years, largely due to the advantageous legal climate within the state of Texas, only a small percentage of APS paid losses have met reinsurance coverage limits; consequently, APS was able to obtain reinsurance coverage for 2011 and 2010 at favorable rates. The APS reinsurance agreements base the amounts due to reinsurers, in part, on expected losses.

 $(14,751) (2.6%)
Net premiums earned consist of gross premiums earned less the portion of earned premiums that we cede to our reinsurers for their assumption of a portion of our losses. Because premiums are generally earned pro rata over the entire policy period, fluctuations in premiums earned tend to lag those of premiums written. Generally, our policies carry a term of one year, but as discussed above, we renew certain policies with a two-year term. Tail coverage premiums are generally 100% earned in the period written because the policies insure only incidents that occurred in prior periods and are not cancellable. Additionally, ceded premium changes due to commutations or re-estimationchanges to estimates of premiums owed under reinsurance premiums incurred for prior accident yearsagreements are fully earned in the period of change.
NetPremiums earned were lower in 2012, as compared to 2011, principally due to the pro-rata effect of lower non-tail physician premiums written during the preceding twelve months, partially offset by higher tail premiums written and earned (includingin 2012.

Net Investment Income, Equity in Earnings (Loss) of Unconsolidated Subsidiaries, Net Realized Investment Gains (Losses)
Net Investment Income
Net investment income is primarily derived from the income earned by our fixed maturity securities and also includes income from our short-term and cash equivalent investments, dividend income from equity securities, earnings from other investments and increases in the cash surrender value of business owned life insurance contracts. Investment fees and expenses are deducted from investment income.

Fixed Maturities
The decrease in income duringAs compared to 2011, primarily reflects lower yields on our portfolio partially offset by higher average investment balances. During the first six months of 2011, our Treasury Inflation-Protected Securities (TIPS) portfolio outperformed our other fixed maturities, and our 2011 results include higher earnings from our TIPS of approximately $1.5 million. Our TIPS portfolio may not continue to outperformfixed maturity investments declined in 2012.
The overall yield on our portfolio declined in 2011 as we were not able to reinvest proceeds from maturities, pay-downs and sales at rates comparable to expiring rates while maintaining our asset quality and the duration of our portfolio. Additionally, the yields on fixed maturity securities acquired in the APS transaction, after adjustment as required by GAAP purchase accounting rules, approximated market yields on the acquisition date of November 30, 2010 and lowered our average consolidated tax equivalent yield by approximately 9 basis points. Average yields for our available-for-sale fixed maturity securities during 2011 and 2010 are as follows:
  Year Ended December 31
  2011 2010
Average income yield 4.0% 4.3%
Average tax equivalent income yield 4.6% 5.0%
The level of our investment in fixed maturity securities varies depending upon a number of factors, including, among others, our operating cash needs, anticipated shifts in credit markets, the attractiveness of other investment alternatives, and cash needed for acquisitions or other capital purposes. In 2011, as compared to 2010, our Our average investment in fixed maturities increaseddecreased by approximately 4%.3% in 2012. In 2012 a portion of the proceeds from sales and maturities of our fixed maturities were not reinvested but instead were utilized for other corporate purposes which included payment of shareholder dividends, repayment of debt and partial funding of acquisitions. Yields for our fixed maturity portfolio were generally lower in 2012. As securities matured, were paid down or sold, in order to maintain the asset quality and duration of our portfolio, most funds reinvested were at lower rates, although we did add certain higher yielding fixed maturities to our portfolio in 2012 as a means of improving overall yields. Yields for 2012 also reflected lower income from Treasury Inflation-Protected Securities of $1.0 million. Average yields for our fixed maturity securities during the years ended December 31, 2012 and 2011 were as follows:
 Year Ended December 31
 2012 2011
Average income yield3.9% 4.0%
Average tax equivalent income yield4.5% 4.6%
Equities and Other Invested Assets
Income from our equity portfolio increased in 2012 as compared to 2011 and primarily reflects higher average investment balances in 2012. A portion of the increased investment is attributable to an interest in a private investment LLC, classified as a part of Other investments during 2011, that was converted into publicly traded equity securities during 2012. The 2012 income decline for Other invested assets was principally attributable to this conversion.

We began investing in tax credit limited partnerships in 2010. Our tax credit investments are designed to generate investment returns by providing tax benefits to fund investors in the form of project operating losses and tax credits. Our tax credit partnerships reduced our tax expenses by approximately $5.7$10.0 million during 2011,the year ended December 31, 2012, while we recognized $5.6$6.4 million of pre-tax amortization ($3.64.2 million after tax) on these investments as noted in the table above.
Non-GAAP Financial Measure – Tax Equivalent Investment Result
We believe that to fully understand our investment returns it is important to consider the current tax benefits associated with certain investments; therefore, we impute a pro forma tax-equivalent investment result by adjusting the current tax benefit into the amount of investment income a taxable investment would need to produce to fairly compare to an investment with preferential tax treatment. We believe this better reflects the economieseconomics of our decision to invest in certain asset classes that are either taxed at lower rates and/or result in reductions to our current federal income tax expense.

We recognized impairments of $0.1 million and $3.8 million induring the years ended December 31, 2012 and 2011, and $3.4 million in 2010respectively, related to an interest in an LLC classified as a part of Other investments which we accountaccounted for using the cost method. The LLC has notified us of its intentionannounced in 2011 that it planned to convert to a publicpublicly traded investment fund and we have reducedimpaired the carrying valueinvestment to the NAV reported by the fund. The conversion occurred during the second quarter of 2012.
We substantially increased the size of our interest inequity trading portfolio over the LLC toprevious year. Unrealized trading portfolio gains reflect the most recently reported fund NAV.
We recognized credit-related impairments in earnings of $1.6 million in 2011, related to residential mortgage-backed securities. Expected future cash flows were less than our carrying value for these securities; therefore, we reduced the carrying value of our interest in these securities and recognized the loss in our 2011 net income.
Trading portfolio losses during 2011 reflect the overall decline in stock market yields, further impacted by higher average balances in our portfolio and an overall improvement in 2011 as compared to 2010.stock market yields.
FairGains (losses) from changes in the fair value adjustments areof liabilities were entirely attributable to our election of fair value treatment for both the 2019 Note Payable and the related interest rate swap, as discussedboth of which we repaid in NotesJuly 2012. For more information, see Note 3 and Note 10 of the Notes to Consolidated Financial Statements.
Other Income
Other Income is comprised primarily of commission and fee income from our agency operations, other fee revenues, rental income and other miscellaneous revenues. The revenue is not a principal source of income and often varies among periods. DuringThe decrease in 2012 as compared to 2011 we recognizedprimarily reflected other income of $4.9 million recognized in 2011 related to a confidential settlement of litigation with a service provider. The remaining increase is primarily attributable toprovider and a gain of approximately $0.8 million recognized on the sale of a building in 2011.
Losses and Loss Adjustment Expenses
The determination of calendar year losses involves the actuarial evaluation of incurred losses for the current accident year and the actuarial re-evaluation of incurred losses for prior accident years, including an evaluation of the reserve amounts required for losses in excess of policy limits.
Accident year refers to the accounting period in which the insured event becomes a liability of the insurer. For claims-made policies, which represent over 90% of the Company’s business, the insured event generally becomes a liability when the event is first reported to the insurer. For occurrence policies the insured event becomes a liability when the event takes place. We believe that measuring losses on an accident year basis is the best measure of the underlying profitability of the premiums earned in that period, since it associates policy premiums earned with the estimate of the losses incurred related to those policy premiums.

As compared to 2010,The 2012 decrease in our 2011 current accident year net loss ratio reflects a decrease attributablethe following:
In 2012 we decreased our loss reserves related to higher earned premiums resulting from the re-estimation of amounts due to reinsurers (discussed further under the header Premiums), the effect of which was partially offset by a ratio increase attributable to coverages provided to qualified insureds for death, disability and retirement (DDR) coverage endorsements provided to our insureds while in 2011 we increased loss reserves for this coverage. The reserve for DDR is actuarially estimated and is affected by changes in the number of insureds expected to benefit from the coverage endorsement.
Net earned premium in both 2012 and 2011 was increased by reductions to amounts owed under reinsurance agreements (see "Net Premiums Earned"). The reductions had a greater effect on the net loss ratio in 2012.
A commutation recorded in 2011 increased the 2011 net loss ratio; no commutation was recorded in 2012.
More of our net earned premium was from tail coverages in 2012. This increases our average net loss ratio because we expect higher losses for tail coverages than for our other professional liability coverages.
We recognized favorable loss development related to prior accident years of $272.0 million for the year ended December 31, 2012 and $325.9 million for the year ended December 31, 2011 and $234.0 million for the year ended December 31, 2010. Detailed information regarding the2011. A detailed discussion of factors influencing our recognition of loss development recognized is included in the Critical Accounting Estimates section of Item 7, under the caption “Reserve for Losses and Loss Adjustment Expenses”.Expenses.” Information provided includes the amount of development recognized by accident year and the factors considered and judgments made to determine the amount of development recognized.
Assumptions used in establishing our reserve are regularly reviewed and updated by management as new data becomes available. Any adjustments necessary are reflected in the 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, as was the case in both 20112012 and 2010.2011.
Recoveries
We recognized favorable prior accident year loss development of approximately $49.4 million in 2012 and $39.9 million in 2011 and $1.1 million in 2010 related to our reinsured coverage layers (generally, losses exceeding $1 million) and recognized offsetting reductions to loss recoveries of $49.4 million in 2012 and $39.9 million in 2011 and $1.1 million in 2010.2011. Because the reduction exceeds allreductions exceed other recoveries for the period,during each year, recoveries increaseincreased rather than decreasedecreased net losses for the yearyears ended December 31, 2012 and 2011.
We similarly reduced our estimates of the premium due to reinsurers by $34.3 million and $30.6 million in 2012 and $13.4 million in 2011, and 2010, respectively, because the premium due to reinsurers is based in part on amounts recovered.

Insurance Operation Expenses
Insurance operation expenses in 2012 as compared to 2011 primarily reflected the net effect of the following:
We incurred expenses related to the mergers of IND and Medmarc of approximately $1.5 million in 2012.
As discussed in Notes 1 and 7 of the Notes to Consolidated Financial Statements, we adopted, on a prospective basis, new FASB guidance related to the deferral of policy acquisition costs. The new guidance affects the timing, but not the amount of acquisition costs ultimately expensed, as the decrease in the expense deferral reduces amortization of policy acquisition costs by the same amount, recognized over the term of the associated successful policies. Our 2012 expenses reflect a net increase of approximately $1.9 million in 2012 due to adoption of the new guidance, as we expensed approximately $4.2 million of policy acquisition costs that under prior guidance would have been deferred to later periods but also recognized amortization expense that was approximately $2.3 million lower than would have been recognized under previous guidance.
Exclusive of the effect of the APS acquisition, insurance operation expenses decreased by $5.7 million primarily due to the following:
Amortizationnew FASB guidance, amortization of deferred policy acquisition costs decreased by $2.4was $0.3 million lower in 2012 than in 2011. While amortization was lower in 2012 consistent with the decline in net premiums earned, amortization in 2011 primarily due to lower premium volume.
Various other expense itemswas reduced operating expense by approximately $2.0 million. Lower professional fees, principally due to transaction costs incurred in 2010 but not in 2011, and an increase in the amount of administrative costs allocated to loss adjustment expense contributed to the decrease.
Termination of a captive insurance agreement, managed by ProAssurance, increased 2010 underwriting expense by $2.6 million. There was no similar transaction in 2011.
Lower guaranty fund recoupments in 2011 increased expenses by $1.3 million.
Expenses associated with APS include salary and benefit expenses of approximately $1.2 million in 2011 that are related to workforce reductions. APS policy acquisition expenses are approximately $1.5 million lowerrelated to the acquisition of APS in 2011 than would be considered normal dueNovember 2010. Due to the application of GAAP purchase accounting rules, whereby the assetsno asset for deferred policy acquisition costs were notwas recognized as a part of the purchase price allocation of APS. OurAPS; consequently, amortization of deferred policy acquisition costs in 2011 expense also includeswas reduced.
On a $2.2 million reduction that resulted from asporadic basis our expenses are reduced by recoveries related to the settlement of litigation that is unrelatedlitigation. Recoveries in 2012 were approximately $0.5 million lower (and thus expenses on a net basis were higher) than in 2011.
Costs associated with the operations acquired from APS, primarily compensation costs, were approximately $3.7 million lower in 2012 as compared to 2011.
Higher stock compensation and bonus costs in 2012 as compared to 2011 as well as additional costs incurred related to the enhancement of our normal insurance activities.customer service capabilities increased our 2012 expenses by approximately $5.0 million. We relocated a number of positions in order to create centralized customer service centers. Relocation benefits were provided to affected employees as well as termination benefits for employees unable to relocate. Expenses of $1.6 million related to a deferred compensation agreement with a former senior executive increased our expenses in 2011; there were no comparable expenses in 2012.
Various other operating costs were collectively lower by approximately $3.2 million in 2012.

Agency expensesExpenses
We have historically operated several non-insurancemaintain limited agency operations that both generate premium revenues for our insurance subsidiaries principally insurance agencies that have generatedand earn external commission and service fee revenues. Expenses of our agencyAgency operations that are associated with the generation of premium revenues by our insurance subsidiaries are included in insurance operation expenses in the above table. Expenses of our agency operations that are directly associated with external commission and service fee revenues are included in agency expenses in the above table. InAgency expenses for 2011 we discontinued most externalincluded non-recurring expenses associated with the dissolution of certain agency operations. The decline in agency expenses of $0.9 million reflects the discontinuation of these operations partially offset by costs incurred related to workforce reductions.

Taxes
Our effective tax rate for each period is lower than the 35% statutory rate because a considerable portion of our net investment income is tax-exempt. Other factorsFactors affecting our effective tax rate include the following:

(2)During 2010 we reversed a valuation allowance previously established against deferred tax assets that were capital in character. We determined that it was more likely than not that sufficient sources of taxable capital income would be available in future periods to allow us to fully utilize the deferred tax assets.
(3)A partial redemption of our BOLI increased tax expense in 2010 by approximately $1.3 million; there were no BOLI redemptions during 2011.
Although ourOur effective tax rate is consistent betweendecreased in 2012 as compared to 2011, and 2010, currentprimarily due to an increase in the expected tax expense increasedbenefit from tax credits transferred to us by our tax credit partnership investments. We recognized tax benefits of approximately $23.1$10.0 million induring 2012, related to the credits, compared to tax benefits of $5.7 million during 2011. In 2011 we recorded a current liability of $19.5 million (including interest of $0.9 million) for unrecognized tax benefits.

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.
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. Certain of the securities are held in an unrealized loss position; we do not intend to sell and believe we will not be required to sell any of the debt securities held in an unrealized loss position before its anticipated recovery.
The following table summarizes estimated changes in the fair value of our available-for-sale fixed maturity securities for specific hypothetical changes in interest rates by asset class at December 31, 20122013 and December 31, 20112012. There are principally two factors that determine interest rates on a given security: market interest rates and credit spreads. As different asset classes can be affected in different ways by movements in those two factors, we have broken out our portfolio by asset class in the following table.

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 the 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’sOur cash, restricted cash and short-term investment portfolio at December 31, 20122013 was carried on a cost basis which approximates its fair value. ThisOur portfolio lacks significant interest rate sensitivity due to its short duration.
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, 20122013, 93% of our fixed maturity securities were rated investment grade as determined by Nationally Recognized Statistical Rating Organizations (NRSROs), such as A.M. Best, Fitch, Moody’s and Standard & Poor’s. We believe that this concentration in investment grade securities reduces our exposure to credit risk on our fixed income investments to an acceptable level. However, investment grade securities, in spite of their rating, can rapidly deteriorate and result in significant losses. Ratings published by the NRSROs are one of the tools used to evaluate the credit worthiness of our securities. The ratings reflect the subjective opinion of the rating agencies as to the credit worthiness of the securities, and therefore, we may be subject to additional credit exposure should the rating prove to be unreliable.
We held $1.2 billion of municipal bonds at December 31, 2012. We require the bonds that we purchase to meet our credit criteria on a stand-alone basis. As of December 31, 2012, on a stand-alone basis, our municipal bonds had a weighted average rating of AA.
We also have exposure to credit risk related to our receivables from reinsurers. Our receivables from reinsurers (with regard to both paid and unpaid losses) approximated $251 million at December 31, 2013 and $196 million at December 31, 2012 and $252 million at December 31, 2011., with the 2013 increase primarily attributable to acquisitions. We monitor the credit risk associated with our reinsurers using publicly available financial and rating agency data.
Equity Price Risk
At December 31, 20122013 the fair value of our investment in common stocks was $203254 million. These securities are subject to equity price risk, which is defined as the potential for loss in fair value due to a decline in equity prices. The weighted average beta of this group of securities was 0.96. 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 9.6% to $222278 million. Conversely, a 10% decrease in the S&P 500 Index would imply a decrease of 9.6% in the fair value of these securities to $183229 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.

ITEM 9A. CONTROLS AND PROCEDURES.
Disclosure Controls
Under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, the Company has evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the fiscal year ended December 31, 20122013. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that these controls and procedures are effective.
Disclosure controls and procedures are defined in Exchange Act Rule 13a-15(e) and include the Company’s controls and other procedures that are designed to ensure that information, required to be disclosed by the Company in the reports that it files or submits under the Exchange Act, is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
Management’s Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 20122013 based on the framework in Internal Control–Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 20122013 and that there was no change in the Company’s internal controls during the fiscal year then ended that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
On January 1, 2013 we completed the acquisition of Medmarc Mutual Insurance Company, now Medmarc Casualty Insurance Company (Medmarc). Our management excluded Medmarc's systems and processes from the scope of ProAssurance's assessment of internal control over financial reporting as of December 31, 2013 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 September 2004 (and revised on October 6, 2004). We are excluding Medmarc from that scope because we expect substantially all of its significant systems and processes to be converted to those of ProAssurance during 2014. At December 31, 2013 Medmarc represented $413.3 million or 8.0% of total assets, and $46.5 million or 6.3% of total revenues for the year then ended.
Ernst & Young LLP, an independent registered public accounting firm, has audited the effectiveness of our internal controls over financial reporting as of December 31, 20122013 as stated in their report which is included elsewhere herein.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of ProAssurance Corporation
We have audited ProAssurance Corporation and subsidiaries'subsidiaries’ internal control over financial reporting as of December 31, 2012,2013, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) (the COSO criteria). ProAssurance Corporation and subsidiaries'subsidiaries’ management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management'sManagement’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company'sCompany’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, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, 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'scompany’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'scompany’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'scompany’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.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of ProAssurance Corporation
We have audited the accompanying consolidated balance sheets of ProAssurance Corporation and subsidiaries as of December 31, 20122013 and 2011,2012, and the related consolidated statements of changes in capital, income and comprehensive income, changes in capital, and cash flows for each of the three years in the period ended December 31, 2012.2013. 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, 20122013 and 2011,2012, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2012,2013, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedules, when considered in related 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), ProAssurance Corporation'sCorporation’s internal control over financial reporting as of December 31, 2012,2013, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) and our report dated February 19, 201320, 2014 expressed an unqualified opinion thereon.

1. Accounting Policies
Organization and Nature of Business
ProAssurance Corporation (ProAssurance, PRA or PRA)the Company), a Delaware corporation, is an insurance holding company for wholly-ownedwholly owned specialty property and casualty insurance companies that principally provide professional liability insurance for providershealthcare professionals and facilities, professional liability insurance for attorneys, liability insurance for medical technology and life sciences risks and, effective January 1, 2014, workers' compensation insurance. ProAssurance is also the majority capital provider for Syndicate 1729 at Lloyd's of healthcare services,London (Syndicate 1729) which began writing a range of property and to a lesser extent, providers of legal servicescasualty insurance and other professional services.reinsurance lines effective January 1, 2014. During the years ended December 31, 2013, 2012 and 2011 ProAssurance operatesprimarily operated in the United States of America (U.S.) in a single reportable segment.
Principles of Consolidation
The accompanying consolidated financial statements include the accounts of ProAssurance Corporation and its wholly-owned subsidiaries. Investments in entities where ProAssurance holds a greater than minor interest but does not hold a controlling interest are accounted for using the equity method. All significant intercompany accounts and transactions are eliminated in consolidation.
Basis of Presentation
The preparation of financial statements in conformity with U.S. Generally Accepted Accounting Principlesgenerally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and disclosures related to these amounts at the date of the financial statements. Actual results could differ from those estimates.
Stock Split
TheIn 2012, the Board of Directors of ProAssurance Corporation (the Board) declared a two-for-one stock split of ProAssurance common shares which was effected December 27, 2012 in the form of a stock dividend. All share and per share information provided in this report reflects the effect of the split for all periods presented.
Gain on Acquisition
The year-end deferred tax review resulted in a $3.7 million reduction of the Gain on acquisition recorded for our acquisition of Medmarc. Certain deferred tax liabilities relating to unrealized gains on investments held by Medmarc were not established as a part of the assets acquired and liabilities assumed for Medmarc and as a result the value of the net assets acquired in the transaction were overstated. An adjustment was made to the Gain on acquisition in the fourth quarter of 2013 reducing the gain from $36.0 million to $32.3 million. The adjustment was not quantitatively or qualitatively material to the prior or current period presented.
Accounting Policies
The significant accounting policies followed by ProAssurance in making estimates that materially affect financial reporting are summarized in these notes to the consolidated financial statements.
Recognition of Revenues
Insurance premiums are recognized as revenues pro rata over the terms of the policies, which are generallyprincipally one year in duration.

1. Accounting Policies (continued)
Losses and Loss Adjustment Expenses
ProAssurance establishes its reserve for losses and loss adjustment expenses (reserve("reserve for losses)losses" or "reserve") based on estimates of the future amounts necessary to pay claims and expenses 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.
 Management establishes the reserve for losses after taking into consideration a variety of factors including the conclusions reached by internal actuaries, premium rates, claims frequency, historical paid and incurred loss development trends, the effect of inflation, general economic trends, the legal and political environment, and the reports received from consulting actuaries. Internal actuaries perform an in-depth review of the reserve for losses at least semi-annually using the loss and exposure data of ProAssurance subsidiaries. Management engages consulting actuaries to review subsidiary loss and exposure data and provide reports to Management regarding the adequacy of reserves.
Estimating casualty insurance reserves, and particularly liabilitylong-tailed insurance reserves, is a complex process. Claims may be resolved over anLong-tailed insurance is characterized by the extended period of time between collecting the premium for insuring a risk and the ultimate payment of losses. For ProAssurance the period of time required to resolve claims is often five years or more, and claims may be subject to litigation. Estimating losses for liabilitylong-tailed insurance 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, as was the case in 20122013, 20112012 and 20102011.
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, ProAssurance may make significant adjustments to gross losses that have little effect on its net losses.
Reinsurance Receivables
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 reinsurance to provide for greater diversification of business and to allow management to control exposure to potential losses arising from large risks.
Receivable from Reinsurers on Paid Losses is the estimated amount of losses already paid that will be recoverable from reinsurers. Receivable from Reinsurers on Unpaid Losses 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 determined to be uncollectible is written off in the period in which the uncollectible amount is identified.

Investments
Fair Values
Fair values of investment securities are primarily provided by independent pricing services. The pricing services provide an exchange traded price, if available, or provide an estimated price determined using multiple observable inputs, including exchange traded prices for similar assets. Management reviews valuations of securities obtained from the pricing services for accuracy based upon the specifics of the security, including class, maturity, credit rating, durations, collateral, and comparable markets for similar securities. Multiple observable inputs are not available for certain of our investments, including municipal bonds and corporate debt not actively traded, and investments in limited partnerships/limited liability companies (LPs/LLCs). Management values these municipal bonds and corporate debt either using a single non-binding broker quote or pricing models that utilize market based assumptions that have limited observable inputs. Management values investments in LPs/LLCs based on the net asset value of the interest held, as provided by the fund.
Fixed Maturities and Equity Securities
Fixed maturities and equity securities are considered as either available-for-sale or trading securities.
Available-for-sale securities are carried at fair value, determined as described above, and unrealized gains and losses on such available-for-sale securities are included, net of related tax effects, in Shareholders’ Equity as a component of Accumulated Other Comprehensive Income (Loss).
Investment income includes amortization of premium and accretion of discount related to available-for-sale 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.
Trading portfolio securities are carried at fair value, determined as described above, with the holding gains and losses included in realized investment gains and losses in the current period.
Short-term Investments
Short-term investments, which have a maturity at purchase of one year or less, are primarily comprised of investments in U.S. Treasury obligations and commercial paper. All balances are reported at amortized cost, which approximates fair value.
Other Investments
Investments in LPs/LLCs where ProAssurance has virtually no influence over the operating and financial policies of an investee are accounted for using the cost method. Under the cost method, investments are valued at cost, with investment income recognized when received.
Investment in Unconsolidated Subsidiaries
Investments in LPs/LLCs where ProAssurance is deemed to have influence because it holds a greater than a minor interest are accounted for using the equity method. Under the equity method, the recorded basis of the investment is adjusted each period for the investor’s pro rata share of the investee’s income or loss. Investments in unconsolidated subsidiaries include tax credit partnerships accounted for using the equity method, whereby ProAssurance’s proportionate share of income or loss is included in investment income. Tax credits received from the partnerships are recognized in the period received as a reduction to current tax expenses.
Business Owned Life Insurance (BOLI)
ProAssurance owns life insurance contracts on certain 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.
Realized Gains and Losses
Realized investment gains and losses are recognized on the specific identification basis.

1. Accounting Policies (continued)Realized Gains and Losses
Realized investment gains and losses are recognized on the specific identification basis.
Other-than-temporary Impairments
ProAssurance evaluates its available-for-sale investment securities on at least a quarterly basis for the purpose of determining whether declines in fair value below recorded cost basis for the purpose of determining whether these declines represent other-than-temporary declines. The assessment of whether the amortized cost basis of debt securities, particularly asset-backed debt securities, is expected to be recovered requires management to make assumptions regarding various matters affecting cash flows to be received in the future. The choice of assumptions is subjective and requires the use of judgments; actual credit losses experienced in future periods may differ from management’s estimates of those credit losses.
If there is intent to sell the security or if it is more likely than not that the security will be required to be sold before full recovery of its amortized cost basis, ProAssurance considers a decline in fair value to be an other-than-temporary impairment. Otherwise, ProAssurance considers the following factors in determining whether an investment’s decline is other-than-temporary:
For equity securities:
the length of time for which the fair value of the investment has been less than its recorded basis;
the financial condition and near-term prospects of the issuer underlying the investment, taking into consideration the economic prospects of the issuer’s industry and geographical region, to the extent that information is publicly available;
the historical and implied volatility of the fair value of the security;
For debt securities, an evaluation is made as to whether the decline in fair value is due to credit loss, which is defined as the excess of the current amortized cost basis of the security over the present value of expected future cash flows. Methodologies used to estimate the present value of expected cash flows to determine if a decline is due to a credit loss are:
For non-structured fixed maturities (U.S. Treasury securities, obligations of U.S. Government and government agencies and authorities, obligations of states, municipalities and political subdivisions, and corporate debt) the estimate of expected cash flows is determined by projecting a recovery value and a recovery time frame and assessing whether further principal and interest will be received. ProAssurance considers the following in projecting recovery values and recoverrecovery time frames:
third party research and credit rating reports;
the current credit standing of the issuer, including credit rating downgrades, whether before or after the balance sheet date;
internal assessments and the assessments of external portfolio managers regarding specific circumstances surrounding an investment, which indicate the investment is more or less likely to recover its amortized cost than other investments with a similar structure;
failure of the issuer of the security to make scheduled interest or principal payments;
For structured securities (primarily asset-backed securities), ProAssurance estimates the present value of the security’s cash flows using the effective yield of the security at the date of acquisition (or the most recent implied rate used to accrete the security if the implied rate has changed as a result of a previous impairment or changes in expected cash flows). ProAssurance incorporatesconsiders the most recently available six month averages of the levels of delinquencies, defaults, severities, and prepayments in the securitization, for the parameters applied to the assetscollateral (loans) underlying the securitization in determining the net present valueor, if historical data is not available, sector based assumptions, to estimate expected future cash flows of the cash flows.these securities.
Investments in LPs/LLCs are evaluated for impairment by comparing ProAssurance’s carrying value to net asset value (NAV) of ProAssurance’s interest in the fund as reported by the fund manager. Additionally, Management considers the performance of the fund relative to the market, the stated objectives of the fund, and cash flows expected from the fund and fund audit reports, if available.
TaxInvestments in tax credit partnership investmentspartnerships are evaluated for OTTI by comparingconsidering both qualitative and quantitative factors which include: whether cash flow projections of future operating results offlows currently expected from the underlying projects generatinginvestment, primarily tax benefits, equal or exceed the tax credits to the recordedcarrying value of the investment, taking into consideration ProAssurance’swhether currently expected cash flows are less than those expected at the time the investment was acquired, and ProAssurance's ability and intent to utilizehold the tax credits frominvestment until the investments.recovery of its carrying value.
ProAssurance recognizes other than temporary impairments, including impairments of debt securities due to credit loss, in earnings as a part of net realized investment gains (losses). In subsequent periods, any measurement of gain or loss or impairment is based on the revised amortized basis of the security. Declines in fair value, including impairments of debt

1. Accounting Policies (continued)
Asset-backed securities that have been impaired due to credit or are below investment grade quality are accounted for under the effective yield method. Under the effective yield method estimates of cash flows expected over the life of asset-backed securities are then used to recognize income on the investment balance for subsequent accounting periods.
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.
Restricted Cash
Restricted cash represents cash balances which are not available for immediate or general use. At December 31, 2013 ProAssurance's Restricted cash was comprised entirely of a deposit collateralizing a standby letter of credit entered into as a part of our funding at Lloyd's.
Deferred Policy Acquisition Costs
Costs that vary with and are directly related to the successful 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.
Income Taxes/Deferred Taxes
ProAssurance files a consolidated federal income tax return. Tax-related interest and penalties are recognized as components of tax expense. 
ProAssurance evaluates tax positions taken on tax returns and recognizes positions in the financial statements when it is more likely than not that the position will be sustained upon resolution with a taxing authority. If recognized, the benefit is measured as the largest amount of benefit that has a greater than fifty percent probability of being realized. Uncertain tax positions are reviewed each period by considering changes in facts and circumstances, such as changes in tax law, interactions with taxing authorities and developments in case law, and adjustments are made as considered necessary. Adjustments to unrecognized tax benefits may affect income tax expense and the settlement of uncertain tax positions may require the use of cash.
Deferred federal income taxes arise from the recognition of temporary differences between the basis of assets and liabilities determined for financial reporting purposes and the basis determined for income tax purposes. ProAssurance’s temporary differences principally relate to loss reserves, unearned premium, deferred policy acquisition costs, unrealized investment gains (losses), investment impairmentsbasis differentials for investments, compensation accruals, and intangibles. Deferred tax assets and liabilities are measured using the enacted tax rates expected to be in effect when such benefits are realized. ProAssurance reviews its deferred tax assets quarterly for impairment. If management determines that it is more likely than not that some or all of a deferred tax asset will not be realized, a valuation allowance is recorded to reduce the carrying value of the asset. In assessing the need for a valuation allowance, management is required to make certain judgments and assumptions about the future operations of ProAssurance based on historical experience and information as of the measurement period regarding reversal of existing temporary differences, carryback capacity, future taxable income, including its capital and operating characteristics, and tax planning strategies.
Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. Management is not aware of any such changes that would have a material effect on the Company’s results of operations, cash flows or financial position.
Real Estate
Real Estate balances are reported at cost or, for properties acquired in business combinations, estimated fair value on the date of acquisition, less accumulated depreciation. Real estate principally consists of properties primarily in use as corporate offices, but also includes land (carrying value at both December 31, 2012 and 2011 of $2.1 million).offices. Depreciation is computed over the estimated useful lives of the related property using the straight-line method. Excess office capacity is leased or made available for lease; rental income is included in other income and real estate expenses are included in underwriting, policy acquisition and operating expenses.
Real estate accumulated depreciation was approximately $20.2 million and $18.6 million at December 31, 2012 and 2011, respectively. Real estate depreciation expense for the three years ended December 31, 2012, 2011 and 2010 was $1.4 million, $1.7 million and $1.4 million, respectively.

Real estate depreciation expense for the years ended December 31, 2013, 2012 and 2011 was $1.5 million, $1.4 million and $1.7 million, respectively.
Intangible Assets
Intangible assets with definite lives are amortized over the estimated useful life of the asset. Amortizable intangible assets primarily consist of renewal rights and agency relationships and had a carrying value of $50.251.7 million and $46.150.2 million at December 31, 20122013 and 20112012, respectively with the difference being attributable to intangible assets acquired during 2012.respectively. Intangible assets with an indefinite life, primarily state licenses, are not amortized and had a carrying valuevalues of $14.316.8 million and $14.3 million at both December 31, 20122013 and 20112012., respectively. Increases in both amortizable and non-amortizable intangible assets during 2013 were attributable to intangible assets recognized related to 2013 business combinations. Intangible assets are evaluated for impairment on an annual basis.
Accumulated amortization of intangible assets was $11.216.5 million and $6.711.2 million at December 31, 20122013 and 20112012, respectively. Amortization expense for intangible assets for the three years ended December 31, 20122013, 20112012 and 20102011 was $4.55.3 million, $4.74.5 million and $1.34.7 million, respectively. The estimated aggregateAggregate amortization expense for intangible assets, for eachexcluding amortizable intangible assets recorded through our acquisition of the five succeeding years approximatesEastern, is estimated to be $4.7 million for 2013, $4.45.1 million for 2014, $3.03.1 million for 2015, $2.8 million for 2016 and, $2.72.8 million for 2017 and $2.4 million for 2018.
Goodwill
ProAssurance makes at least an annual assessment as to whether the value of its goodwill assets are impaired. Management evaluates the carrying value of goodwill annually on October 1 and before the annual evaluation if events occur or circumstances change that would more likely than not reduce the fair value below the carrying value. Because ProAssurance operates in a single operating segment and all components within the segment are economically similar, ProAssurance is considered a single reporting unit for the purposes of the impairment evaluation. In assessing goodwill, Management estimates the fair value of the reporting unit on the evaluation date based on the Company’s market capitalization and an expected premium that would be paid to acquire control of the Company (a control premium) and performs a sensitivity analysis using a range of historical stock prices and control premiums. Management concluded in 20122013, 20112012 and 20102011 that the fair value of the Company’s reporting unit exceeded the carrying value and no adjustment to impair goodwill was necessary.
Goodwill is recognized in conjunction with acquisitions as the excess of the purchase consideration for the acquisition over the fair value of identifiable assets acquired and liabilities assumed. The fair value of identifiable assets and liabilities, and thus goodwill, is subject to redetermination within a measurement period of up to one year following completion of an acquisition. During 2013 goodwill was reduced by $1.9 million primarily related to the after-tax effect of the re-determination of the fair value of the reserve for losses associated with a business combination completed in late 2012.
Other Assets
At December 31, 2013 and 2012, Other assets was principally comprised of deposits with third-party agents of $205 million and $153.7 million, respectively, related to the completion of pending business combination transactions. See Note 2.
Treasury Stock
Treasury shares are reported at cost, and are reflected on the balance sheets as an unallocated reduction of total equity.
Share-Based Payments
ProAssurance recognizes compensation cost for share-based payments (including stock options, performance share units, restricted share units, and purchase match units) using the modified prospective method whereby the methodology for recognizing compensation expense differs depending upon the grant date of each share-based payment award. Compensation cost for awards granted after January 1, 2006 is recognized based on the grant-date fair value of the award over the relevant service period of the award; for awards that vest in increments (graded vesting), compensation cost is recognized over the relevant service period for each separately vested portion of the award. Compensation cost for awards granted prior to January 1, 2006 but not vested on January 1, 2006 is recognized over the remaining service period related to those awards, using the same calculation methodologies, including grant-date fair values, as was used to prepare pro forma disclosures prior to January 1, 2006. Excess tax benefits (tax deductions realized in excess of the compensation costs recognized for the exercise of the awards, multiplied by the incremental tax rate) are reported as financing cash inflows.

Subsequent Events
In connection with its preparation of the Consolidated Financial Statements, ProAssurance has evaluated events that occurred subsequent to December 31, 20122013, for recognition or disclosure in its financial statements and notes to the financial statements.
Accounting Changes Adopted
Intangibles-Goodwill and Other
Effective for fiscal years beginning after September 15, 2012, the Financial Accounting Standards Board (FASB) revised guidance related to impairment testing of indefinite-lived intangible assets. The new guidance permits an entity to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that an indefinite-lived intangible asset is impaired. Quantitative impairment testing is required only if the assessment of qualitative factors indicates it is more likely than not that impairment exists. ProAssurance adopted the guidance on January 1, 2013. Adoption of this guidance had no material effect on ProAssurance's results of operations or financial position.
Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income
Effective for interim and annual reporting periods beginning after December 15, 2012, the FASB revised guidance related to the disclosure of amounts reclassified out of accumulated other comprehensive income. The most significant provisions of the new guidance require entities to present additional disclosure, either on the face of the income statement or in the notes, regarding significant amounts reclassified, in their entirety, from accumulated other comprehensive income to net income. ProAssurance adopted the guidance on January 1, 2013. Adoption of this guidance had no material effect on ProAssurance’s results of operations or financial position as it impacts disclosures only.
Disclosures About Offsetting Assets and Liabilities
Effective for fiscal years beginning on or after January 1, 2013, the FASB revised guidance related to disclosures about certain assets and liabilities in an entity’s financial statements. The guidance requires disclosures related to the net and gross positions of certain financial instruments and transactions that are either eligible for offset in accordance with existing GAAP guidance or subject to an agreement that requires such offset. The guidance must be applied retrospectively for all prior periods presented. ProAssurance adopted the guidance on January 1, 2013. Adoption of this guidance had no material effect on ProAssurance’s results of operations or financial position as it impacts disclosures only.
Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts
Effective for fiscal years beginning after December 15, 2011, the FASB revised guidance regarding the interpretation of which costs relating to the acquisition of new or renewal insurance contracts qualify for deferral. The guidance permits deferral of qualifying costs only when associated with successful contract acquisitions. Internal selling agent and underwriter salary and benefit costs allocated to unsuccessful contracts, as well as advertising costs, are excluded. The guidance must be applied prospectively,permitted but may be applied retrospectively for all prior periods.did not require retrospective application. ProAssurance prospectively adopted the guidance on January 1, 2012. Adoption of this guidance had no material effect on ProAssurance’s results of operations or financial position.

1. Accounting Policies (continued)
Fair Value Measurements
Effective for interim and annual reporting periods beginning after December 15, 2011, the FASB revised guidance related to fair value measurements and disclosures, all of which are to be applied prospectively. The new guidance increases disclosure requirements regarding valuation methods used to determine fair value measurements categorized as Level 3, as well as the sensitivity to change of those measurements, and requires additional disclosures regarding the consideration given to highest and best use in fair value measurements of nonfinancial assets. The guidance also requires that when fair value measurements of items not carried at fair value are disclosed, the fair value measurements are to be categorized by level of the fair value hierarchy. Additionally, the guidance also clarifies or revises certain fair value measurement principles related to the valuation of financial instruments managed within a portfolio, the valuation of instruments classified as a part of shareholders’ equity, the appropriate application of the highest and best use valuation premise, and the consideration of premium and discounts in a fair value measurement. ProAssurance adopted the guidance on January 1, 2012. Adoption of this guidance had no material effect on ProAssurance’s results of operations or financial position.
Accounting Changes Not Yet Adopted

Effective for fiscal years beginning after SeptemberDecember 15, 2012,2014, the FASB revisedissued guidance relatedwhich permits qualified reporting entities to impairment testinguse a new accounting method, the proportional amortization method, for investments in qualified affordable housing projects. Under the new method the initial cost of indefinite-lived intangible assets. Thean investment is amortized in proportion to the tax benefits received, and investment performance is recognized as a component of income tax expense (benefit) rather than as a component of investment income. ProAssurance is in the process of evaluating the effect that the use of the new guidance permits an entity to assess qualitative factors to determinemethod would have on its results of operations and financial position and whether it meets the existence of events and circumstances indicates that it is more likely than not that an indefinite-lived intangible asset is impaired. Quantitative impairment testing is required only ifqualification requirements for using the assessment of qualitative factors indicates it is more likely than not that impairment exists.new method. ProAssurance plans to adopt the guidance beginning January 1, 2013.2015.
Liabilities-Obligations Resulting from Joint and Several Liability Arrangements
Effective for fiscal years beginning after December 15, 2013, the FASB revised guidance related to obligations resulting from joint and several liability arrangements. The new guidance requires an entity to recognize, measure and disclose obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date, except for obligations already addressed within existing GAAP guidance, with retrospective application required for such arrangements existing at the beginning of the fiscal year of adoption. ProAssurance plans to adopt the guidance beginning January 1, 2014. Adoption of this guidance is expected to have no effect on ProAssurance's results of operations or financial position.

2. AcquisitionsBusiness Combinations
All entities acquired in 20122013 and 20102012 were accounted for in accordance with GAAP relating to business combinations and are considered to be a part of ProAssurance’s sole reporting segment, the professional liability segment.combinations. No entities were acquired in 2011.
During 2012, ProAssurance completed an acquisition of a reciprocal exchange that converted to a stock insurance company upon acquisition. The acquisition was not material to ProAssurance.
On November 30, 2010 ProAssurance acquired 100% of the outstanding shares of American Physicians Service Group, Inc. (APS) as a means of expanding its professional liability business. Total purchase consideration transferred had a fair value of $237 million on the acquisition date and included cash of $233 million and deferred compensation commitments of $4 million. ProAssurance expensed APS transaction costs of approximately $2 million during 2010. The purchase consideration was allocated to the assets acquired and liabilities assumed based on their estimated fair values on the acquisition dates. The excess of the purchase price over the net fair value of the identifiable assets acquired and liabilities assumed was recognized as goodwill. During 2011 goodwill initially recorded related to the purchase of APS was reduced by $1.8 million to $37.3 million related to the completion of the valuation of pre-acquisition tax liabilities.
The following table provides Pro Forma Consolidated Results for the year ended December 31, 2010 as if the APS transaction had occurred on January 1, 2009. ProAssurance Actual Consolidated Results have been adjusted to reflect the following, net of related tax effects:
The inclusion of APS operating results for the period preceding the APS acquisition date in 2010. ProAssurance 2010 Actual Consolidated Results include APS revenues of $6.2 million and earnings of $1.0 million attributable to the period subsequent to November 30, 2010.
The effects of APS workforce reductions as if those workforce reductions had occurred in 2009.
The exclusion of the direct costs of completing the APS transaction.
For periods subsequent to the acquisition date, amortization of policy acquisition costs. ProAssurance Actual Consolidated Results do not include such amortization because, in accordance with GAAP, assets for deferred policy acquisition costs were not recognized as a part of the purchase price allocation of APS.
For periods preceding the acquisition date, amortization of intangible assets and debt security premiums/discounts recorded as a part of the APS purchase price allocation.

On January 1, 2013, ProAssurance completed the acquisition of Medmarc Mutual Insurance Company, now Medmarc Casualty Insurance Company (Medmarc), through a sponsored demutualization. Medmarc is based in Chantilly, Virginia and provides products liability insurance for medical technology and life sciences companies and also provides legal professional liability insurance. ProAssurance acquired Medmarc for cash of $153.7 million, including the funding of future policy credits for eligible members of $7.5 million. Allocation of the Medmarc purchase consideration to the assets acquired and liabilities assumed was not complete as of the date of this report. ProAssurance transferred all of the cash required to complete the transaction ($153.7 million) to a third-party conversion agent for the benefit of Medmarc eligible members on December 27, 2012; the deposit was classified as a part of Other Assets at December 31, 2012. ProAssurance incurred expenses related to the purchase of approximately $2.6 million during the year ended December 31, 2013 and approximately $1.0 million during the year ended December 31, 2012. These expenses were included as a part of operating expenses in the periods incurred.
The purchase consideration for Medmarc was allocated to the assets acquired and liabilities assumed based on their estimated fair values on the acquisition date, as shown in the table below. The purchase consideration was less than the estimated fair value of the net assets acquired resulting in a gain on the acquisition of $32.3 million, which reflects a reduction of $3.7 million recorded in the fourth quarter of 2013, as discussed in Note 1. ProAssurance believes it was able to acquire Medmarc for less than the fair value of its net assets due to Medmarc's declining premium base and its small capital position relative to other insurers in the medical technology and life sciences products liability insurance market.

ProAssurance believes that all contractual cash flows related to acquired receivables will be collected. The fair value of reserves for losses and loss adjustment expenses and related reinsurance recoverables were estimated based on the present value of the expected underlying net cash flows, including a 5% profit margin and a 5% risk premium, and were determined to be materially the same as the recorded cost basis acquired.

The following table provides Pro Forma Consolidated Results for the years ended December 31, 2013 and 2012 as if the Medmarc transaction had occurred on January 1, 2012. Pro Forma Consolidated Results reflect ProAssurance Actual Consolidated Results adjusted by the following, net of related tax effects:
For the year ended December 31, 2012, the ProAssurance 2012 Actual Consolidated Results did not include Medmarc, and have been adjusted to include Medmarc's 2012 operating results. ProAssurance Actual Consolidated Results for the year ended December 31, 2013 included Medmarc operating results (Revenue of $46.5 million and Net Income of $15.7 million).
Certain costs included in ProAssurance Actual Consolidated Results for the year ended December 31, 2013 have been reported in the Pro Forma Consolidated Results as if the costs had been incurred for the year ended December 31, 2012. Such costs include direct transaction costs and certain compensation costs directly related to the integration of Medmarc operations.
Prior to the acquisition date, Medmarc reported on a statutory basis and expensed policy acquisition costs associated with successful contracts as incurred. After the acquisition date, in accordance with GAAP, Medmarc policy acquisition costs associated with successful contracts were capitalized and amortized to expense as the related premium revenues were earned, but no amortization was recognized for Medmarc policies written prior to the acquisition date. The Pro Forma Consolidated Results for both 2013 and 2012 have been adjusted to reflect policy acquisition costs as if Medmarc had followed GAAP guidance for these costs in pre-acquisition periods.
Earnings for the year ended December 31, 2012 were reduced to reflect amortization of intangible assets and debt security premiums and discounts recorded as a part of the Medmarc purchase price allocation.
The non-taxable gain on the acquisition of $32.3 million that was included in ProAssurance Actual Consolidated Results for the year ended December 31, 2013 has been reported in the Pro Forma Consolidated Results as being recognized during the year ended December 31, 2012.

During 2012, ProAssurance also completed an acquisition of a reciprocal exchange that converted to a stock insurance company upon acquisition. The acquisition was not material to ProAssurance.
On January 1, 2014, ProAssurance completed the acquisition of Eastern Insurance Holdings, Inc. (Eastern) (NASDAQ: EIHI) by purchasing 100% of its outstanding common shares for cash of $205 million. Eastern is based in Lancaster, Pennsylvania and specializes in workers' compensation insurance and reinsurance products and services, including a segregated portfolio cell reinsurance business. Allocation of the Eastern purchase consideration to the assets acquired and liabilities assumed was not complete as of the date of this report. ProAssurance transferred all of the cash required to complete the transaction to a third-party agent for the benefit of Eastern eligible shareholders on December 27, 2013; the deposit was classified as a part of Other Assets at December 31, 2013.

3. Fair Value Measurement
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three level hierarchy has been established for valuing assets and liabilities based on how transparent (observable) the inputs are that are used to determine fair value, with the inputs considered most observable categorized as Level 1 and those that are the least observable categorized as Level 3. Hierarchy levels are defined as follows:
 Level 1:quoted (unadjusted) market prices in active markets for identical assets and liabilities. For ProAssurance, Level 1 inputs are generally quotes for debt or equity securities actively traded in exchange or over-the-counter markets.
 Level 2:market data obtained from sources independent of the reporting entity (observable inputs). For ProAssurance, Level 2 inputs generally include quoted prices in markets that are not active, quoted prices for similar assets or liabilities, and results from pricing models that use observable inputs such as interest rates and yield curves that are generally available at commonly quoted intervals.
 Level 3:the reporting entity’s own assumptions about market participant assumptions based on the best information available in the circumstances (non-observable inputs). For ProAssurance, Level 3 inputs are used in situations where little or no Level 1 or 2 inputs are available or are inappropriate given the particular circumstances. Level 3 inputs include results from pricing models for which some or all of the inputs are not observable, discounted cash flow methodologies, single non-binding broker quotes and adjustments to externally quoted prices that are based on management judgment or estimation.
Fair values of assets and liabilities measured at fair value on a recurring basis as of December 31, 20122013 and December 31, 20112012, including financial instruments for which ProAssurance has elected fair value, are shown in the following tables. The tables also indicate the fair value hierarchy of the valuation techniques utilized to determine those fair values. For some assets, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. When this is the case, the asset is categorized based on the level of the most significant input to the fair value measurement. Assessments of the significance of a particular input to the fair value measurement requires judgment and consideration of factors specific to the assets being valued.

The fair values for securities included in the Level 2 category, with the few exceptions described below, have been developed by one of several third party, nationally recognized pricing services, including services that price only certain types of securities. Each service uses complex methodologies to determine values for securities and subject the values they develop to quality control reviews. Management has selected a primary source for each type of security in the portfolio, and reviews the values provided for reasonableness by comparing data to alternate pricing services and to available market and trade data. Values that appear inconsistent are further reviewed for appropriateness. If a value does not appear reasonable, the valuation is discussed with the service that provided the value and would be adjusted, if necessary. No such adjustments were necessary in 20122013 or 2011.

Level 2 Valuations
Below is a summary description of the valuation methodologies primarily used by the pricing services for securities in the Level 2 category, by security type:
U.S. Treasury obligations are valued based on quoted prices for identical assets, or, in markets that are not active, quotes for similar assets, taking into consideration adjustments for variations in contractual cash flows and yields to maturity.
U.S. Government-sponsored enterprise obligations are valued using pricing models that consider current and historical market data, normal trading conventions, credit ratings, and the particular structure and characteristics of the security being valued, such as yield to maturity, redemption options, and contractual cash flows. Adjustments to model inputs or model results are included in the valuation process when necessary to reflect recent events, such as regulatory, government or corporate actions or significant economic, industry or geographic events that would affect the security’s fair value.
State and municipal bonds are valued using a series of matrices that consider credit ratings, the structure of the security, the sector in which the security falls, yields, and contractual cash flows. Valuations are further adjusted, when necessary, to reflect recent events such as significant economic or geographic events or ratings changes that would affect the security’s fair value.

Corporate debt with multiple observable inputs consists primarily of corporate bonds, but also includes a small number of bank loans. The methodology used to value Level 2 corporate bonds is the same as the methodology previously described for U.S. Government-sponsored enterprise obligations. Bank loans are valued by an outside vendor based upon a widely distributed, loan-specific listing of average bid and ask prices published daily by an investment industry group. The publisher of the listing derives the averages from data received from multiple market-makers for bank loans.
Residential and commercial mortgage backed securities. Agency pass-through securities are valued using a matrix, considering the issuer type, coupon rate and longest cash flows outstanding. The matrix is developed daily based on available market information. Agency and non-agency collateralized mortgage obligations are both valued using models that consider the structure of the security, current and historical information regarding prepayment speeds, ratings and ratings updates, and current and historical interest rate and interest rate spread data. EvaluationsValuations of Alt-A mortgages include a review of collateral performance data, which is generally updated monthly.
Other asset-backed securities are valued using models that consider the structure of the security, monthly payment information, current and historical information regarding prepayment speeds, ratings and ratings updates, and current and historical interest rate and interest rate spread data. Spreads and prepayment speeds consider collateral type. EvaluationsValuations of subprime home equity loans use the same evaluationvaluation methodology as previously described for Alt-A mortgages.
Short-term investments included in the Level 2 category are commercial paper and certificates of depositsecurities maturing within one year, carried at cost which approximates the fair value of the security due to the short term to maturity.
 Level 3 Valuations
Below is a summary description of the valuation processes and methodologies used as well as quantitative information regarding securities in the Level 3 category.
Level 3 Valuation Processes
Level 3 securities are priced by the Vice President of Investments for our subsidiaries, who reports to the Chief Financial Officer.
Level 3 valuations are computed quarterly. Prices are evaluated quarterly against prior period prices and the expected change in price.
Exclusive of Investments in unconsolidated subsidiaries, which are valued at NAV,net asset value (NAV), the securities noted in the disclosure are primarily NRSRO rated corporate debt instruments for which comparable market inputs are commonly available for evaluating the securities in question. Valuation of these corporate debt instruments is not overly sensitive to changes in the unobservable inputs used.

Level 3 Valuation Methodologies
State and municipal bonds consists of auction rate municipal bonds valued internally using either published quotes for similar securities or values produced by using a model based on discounted cash flowsflow models using yields currently available on fixed rate securities with a similar term and collateral, adjusted to consider the effect of a floating rate and a premium for illiquidity. At December 31, 20122013 and, 99% of the securities were rated; the average rating was December 31, 2011A all of these bonds were rated A- or better..
Corporate debt with limited observable inputs consists of corporate bonds and, at December 31, 2012, private placement senior notes guaranteed by large regional banks and certain corporate bonds.banks. Valuations are determined using dealer quotes for similar securities or discounted cash flow models using yields currently available for similar securities. Similar securities are defined as securities having like terms and payment features that are of comparable credit quality. Assessments of credit quality are based on NRSRO ratings, if available, or are subjectively determined by management if not available. At December 31, 20122013, the average rating of rated securities was A-.
Other asset-backed securities consists of securitizations of receivables valued using dealer quotes for similar securities or discounted cash flow models using yields currently available for similar securities.
Investment in unconsolidated subsidiaries and Other investments consist of limited partnership (LP) and limited liability company (LLC) interests valued using the net asset value (NAV)NAV provided by the LP/LLC, which approximates the fair value of the interest.

Transfers
There were no transfers between the Level 1 and Level 2 categories during 2012 or. Short-term investments of 2011$7.2 million were transferred from Level 2 to Level 1 as of the end of 2013.
Transfers shown in the preceding Level 3 Tables arewere as of the end of the period and were to or from Level 2, unless otherwise noted.
The transferstransfer in for Investment in unconsolidated subsidiaries reported in the Level 3 Tables for 2013 reflected an interest in an LP previously accounted for using the cost method and thus not carried at fair value. During 2013, the interest began to be accounted for using the equity method which approximates fair value.
Transfers of Other investments reported in the Level 3 Tables for 2012 and 2011related to an interest in an LLC. The interest in the LLC, a cost method investment, was not carried at fair value at December 31, 2010. During 2011, the LLC announced a planned conversion to a public fund. Subsequent to the announcement, ProAssurance, through the recognition of OTTI, carried the LLC interest at fair value, based on the NAV provided by fund management; such valuation is considered to be in the Level 3 category. The LLC converted into a publicly traded investment fund during the second quarter of 2012 and the interest in the LLC was valued using Level 1 inputs at December 31, 2012.
All remaining transfers during 20122013 and 20112012 related to securities held for which there was littlethe level of market activity for identical or nearly identical securities during thevaries from period to period. The securities were valued using multiple observable inputs when those inputs were available; otherwise the securities were valued using limited observable inputs.

Fair Value Option Elections
The2011 ProAssurance held a note payable, the 2019 Note Payable, (the Note) and a related interest rate swap agreement (the Swap) were repaid in July 2012, as discussed in Note 10. Prior to repayment,, both the Note and the Swapof which were measured at fair value on a recurring basis, with changes in the fair value of each liability recorded in net realized investment gains (losses). ProAssurance assumed both liabilities as part of a previous acquisition. The fair value option was elected for the Note and the Swapeach because valuation at fair value better reflected the economics of the related liabilities and eliminated the inconsistency that would have otherwise resulted from carrying the 2019 Note Payable on an amortized cost basis and the Swap at fair value. Both liabilities were repaid in July 2012. The fair values of these liabilities were determined using the present value of the expected underlying cash flows of each instrument, discounted at rates available on the valuation date for similar instruments issued by entities with a similar credit standing to ProAssurance.

The fair value of the BOLI was equal to the cash surrender value associated with the policies on the valuation date.
Investment in unconsolidated subsidiaries consisted of investments in tax credit partnerships, accounted for using the equity method with the carrying value approximating ProAssurance’s initial investment commitment to the partnership less a pro rata portion of partnership operating losses over the period the investment has been held. The estimated fair value of the partnership is based on the net present value of the expected cash flows from the partnership and considers the timing of tax benefits expected to be received, the funding schedule for the partnership, and current rates for investments with similar risk structures and repayment periods.
Other Investmentsinvestments listed in the table above include interests in certain investment fund LPs/LLCs accounted for using the cost method, investments in Federal Home Loan Bank (FHLB) common stock carried at cost, and an annuity investment carried at amortized cost. The estimated fair value of the LP/LLC interests iswas based on the NAVNAVs provided by the LP/LLC managers. The estimated fair value of the FHLB common stock iswas based on the amount ProAssurance would receive if its membership were canceled, as the membership cannot be sold. The fair value of the annuity iswas the present value of the expected future cash flows discounted using a rate available in active markets for similarly structured instruments.
Investment in Unconsolidated Subsidiaries consists of investments in tax credit partnerships and a non-controlling interest in a limited liability company. Fair values of investments in tax credit partnerships are based on the present value of the cash flows expected to be generated by the partnerships discounted at rates for investments with similar risk structures and repayment periods. The fair value of the LLC interest is estimated as the proceeds ProAssurance would receive upon liquidation of the LLC.
The fair value of the BOLI is the cash surrender value associated with the policies on the valuation date.
Other Assetsassets and Other Liabilitiesliabilities primarily consistconsisted of related investment assets and liabilities associated with funded deferred compensation agreements. Other Liabilities also includes certain contractual liabilities related to prior business combinations. Fair values of the funded deferred compensation assets and liabilities arewere based on the NAVs of the underlying securities. Other assets also included a secured note receivable and an unsecured receivable under a revolving credit agreement. Fair value of these receivables was based on the present value of expected cash flows from the receivables, discounted at market rates on the valuation date for receivables with similar credit standings and similar payment structures. At December 31, 2012, Other liabilities also included certain contractual liabilities related to prior business combinations. The fair values of the business combination liabilities arewere based on the present value of the expected future cash flows,outflows, discounted at ProAssurance’s assumed incremental borrowing rate on the valuation date for unsecured liabilities with similar repayment structures.
The fair valuevalues of the long-term debt isand revolving credit agreement were estimated based on the present value of expected underlyingfuture cash flows of the debt,outflows, discounted at rates available on the valuation date for similar debt issued by entities with a similar credit standing to ProAssurance or, if issued by an insurance subsidiary, the subsidiary issuing the debt.

* Unfunded commitments are included in the carrying value of tax credit partnerships, only.
Tax credit partnershipspartnership interests held by ProAssurance generate investment returns by providing tax benefits to fund investors in the form of project operating losses and tax credits. The related properties are principally low income housing projects. ProAssurance's ownership percentage relative to two of the tax credit partnership interests was almost 100%; these interests had a carrying value of $62.4 million at December 31, 2013. ProAssurance's ownership percentage relative to the remaining tax credit partnership interests was less than 20%; these interests had a carrying value of $79.8 million at December 31, 2013. All are accounted for under the equity method as ProAssurance does not have the ability to exert control over the partnerships.
The Secured debt fund is structured to provide interest distributions and capital appreciation primarily through investments in senior secured debt.
The Long equity fund targets long-term total returns through holdings in public international companies.
The Long/Short equity fund LP targetsfunds target absolute returns using a strategystrategies designed to take advantage of event-driven market opportunities. ProAssurance’s interest in one investment LP increased as other investors liquidated their holdings, and ProAssurance therefore determined it appropriate to begin applying the equity method of accounting instead of the previously applied cost method. When there is a change from the cost to the equity method, GAAP requires retroactive recording of accumulated earnings since the origination of the investment. As the amounts are not material in the current period or any of the prior periods affected, prior period financial statements have not been restated. Accordingly, Equity in earnings (loss) of unconsolidated subsidiaries for 2013 included our portion of the LP’s accumulated earnings from the date of initial investment, which totaled $10.5 million, $8.4 million of which was related to prior periods.
The Non-public equity fund LPsfunds hold diversified private equities and are structured to provide capital appreciation.
The Business LLC interest is a convertible preferred interest in a service-related business that began business operations in 2011. The preferred interest can be converted into a non-controlling common interest in May 2015, but conversion is not required. As of December 31, 2012 the carrying value of the interest was zero due to the recognition of losses incurred to-date by the LLC.

The securities were evaluated for impairment as of December 31, 2011.2013

Each quarter, ProAssurance performs a detailed analysis for the purpose of assessing whether any of the securities it holds in an unrealized loss position have suffered an other-than-temporary impairment in value. A detailed discussion of the factors considered in the assessment is included in Note 1.
Fixed maturity securities held in an unrealized loss position at December 31, 20122013, excluding asset-backed securities, have paid all scheduled contractual payments and are expected to continue doing so. Expected future cash flows of asset-backed securities held in an unrealized loss position were estimated as part of the December 31, 20122013 impairment evaluation using the most recently available six-month historical performance data for the collateral (loans) underlying the security or, if historical data was not available, sector based assumptions, and equaled or exceeded the current amortized cost basis of the security.

ProAssurance recognized impairments related to corporate debt securities in 2012 and 2011 because the credit standing of the issuers had deteriorated.
ProAssurance recognized impairments in 2012, and 2011 and 2010 related to an interest in an LLC, accounted for using the cost method, that was classified as a part of Other Investments. In 2011, the LLC announced a plan to convert to a publicly traded investment fund, and OTTI was recognized in subsequent periods in order to carry the interest at the NAV reported by the fund. The conversion occurred in 2012. In 2010, the LLC reported realized losses on the sale of securities, and ProAssurance reduced the carrying value of its interest in the LLC in recognition of its pro rata share of those losses.
ProAssurance recognized impairments in 2010 related to certain high-yield securities that management intended to sell.

5. Reinsurance
ProAssurance has various excess of loss, quota share, and cession reinsurance agreements in place.place, with each agreement relating to the policies written during a specified coverage period, typically one year. Historically, the professional liability per claim retention level has varied between 90% and 100% of the first $1 million and between 0% andup to 5% of claims exceeding those levels depending on the coverage year and the state in which business was written. Also, there are various fronting and quota share arrangements that apply to certain healthcare professional policies, generally those associated with a group of affiliated insureds or an insured with a large number of risk exposures. Gross and net written premium associated with such arrangements approximated $37.5 million and $20.2 million, respectively, during the year ended December 31, 2013. Medical technology and life sciences products coverages are separately reinsured, generally with 100% retention on the first $1 million of coverage and between 5% and 33% of coverage exceeding those levels, with additional loss participation if specified limits are exceeded. ProAssurance also insures some large professional and product 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 was as follows (in thousands):

The receivable from reinsurers on unpaid losses and loss adjustment expenses represents Management’s estimate of amounts that will be recoverable under ProAssurance reinsurance agreements. These estimatesMost Company reinsurance agreements base the amount of premium that is due to the reinsurer in part on losses reimbursed or to be reimbursed under the agreement, and may also reflect maximum and minimum amounts of ceded premium. Ceded premium amounts are estimated based uponon Management’s expectation of ultimate losses and the portion of those losses that are allocable to reinsurers according to the terms of the agreements.agreements, including any minimums or maximums. Given the uncertainty of the ultimate amounts of losses,

Management’s estimates of losses and related amounts recoverable may vary significantly from the eventual outcome. Also, premiums ceded under reinsurance agreements wherein the premium due to the reinsurer, subject to certain maximums and minimums, is based in part on losses reimbursed or to be reimbursed under the agreement, and will thus vary when loss estimates are revised. During the years ended December 31, 2013, 2012 and 2011 ProAssurance reduced premiums ceded by $16.4 million, $34.3 million and $30.6$30.6 million,, respectively, due to changes in Management’s estimates of amounts due to reinsurers related to prior accident year loss recoveries.
Reinsurance contracts do not relieve ProAssurance from its obligations to policyholders and ProAssurance remains liable to its policyholders whether or not reinsurers honor their contractual obligations to ProAssurance. ProAssurance continually monitors its reinsurers to minimize its exposure to significant losses from reinsurer insolvencies.
At December 31, 20122013, $81.692.1 million of the total amounts due from reinsurers of $164.0237.9 million (including receivables related to paid and unpaid losses and LAE and prepaid reinsurance premiums, less reinsurance premiums payable) was due from four reinsurers which had an individual balance which exceeded $1020 million. Each of these reinsurers had an A.M. Best credit rating of A or above.
At December 31, 20122013 and 20112012 ProAssurance had no allowance for credit losses related to its reinsurance receivables. During the years ended December 31, 2013, 2012 and 2011 2011no reinsurance balances were written off for credit reasons.
At December 31, 20122013, all reinsurance recoverables were considered collectible. Reinsurance recoverables totaling approximately $1425 million were collateralized by letters of credit or funds withheld. At December 31, 20122013 no amounts due from individual reinsurers exceeded 5% of shareholders’ equity.
There were no significant reinsurance commutations in 2013 or 2012. During 2011,, ProAssurance commuted (terminated) various outstanding reinsurance agreements for approximately $4.3$4.3 million in cash. The commutations reduced Receivable from Reinsurers on Paid Losses and Receivable from Reinsurers on Unpaid Losses, combined, by approximately $4.0$4.0 million (net of cash received) and reduced Reinsurance Premiums Payable by approximately $5.6 million.$5.6 million.
There were no significant reinsurance commutations in 2012 or 2010.

In evaluating the need for a valuation allowance on deferred tax assets, management determined that assets related to capital losses on investments would be realized through a tax planning strategy of selling investments with built in gains.
A valuation allowance of $0.9 million that was established in 2009 related to deferred tax assets acquired in the PICA acquisition was released in 2010. ProAssurance has begun realizing the benefit of these deferred tax assets, and Management believes that sufficient sources of taxable income will be available in the future to allow realization of the currently remaining deferred tax assets.

6. Income Taxes (continued)
The Internal Revenue Service (IRS) has completed an examination of the Company’s 2005 through 2008 returns (the 2005-2008 exam). The 2005-2008 exam resulted in delaying the deductibility of certain bonus compensation which increased taxes due for the 2007 and 2008 tax years but decreased taxes due for the 2009 tax year by an offsetting amount, the effect of which had previously been recorded as an uncertain tax position. The 2005-2008 exam resulted in no adjustment to tax expense (exclusive of interest accruals) and no penalties or fines. Upon finalization of the 2005-2008 exam, uncertain tax positions totaling $8.3 million were deemed effectively settled and were reversed (along with approximately $0.3 million of related accrued interest) in the first quarter of 2011.
The IRS has preliminarily concluded an examination of the 2009 and 2010 returns and has issued a Notice of Proposed Adjustment (NOPA) for these years which would increase ourProAssurance's current tax liability by approximately $130 million. During 2013 ProAssurance is protestingsubmitted a comprehensive written protest to the IRS position and is unableOffice of Appeals regarding certain issues within the NOPA, all of which related to reliably predict the timing of deductions. ProAssurance and the final resolution orIRS have since reached a tentative settlement on the ultimate outcome. The contested issues affect only the timing of when certain expense items are deductiblewhich will result in no additional tax liability for tax and resolution ofProAssurance. Other non-contested issues addressed by the NOPA would have no effect on our recordedare expected to result in a net Federal income tax expense, exclusiverefund of interest found toapproximately $9.6 million. ProAssurance believes that the tentative settlement with the IRS will be due on past-duefinalized during 2014.
At December 31, 2013, ProAssurance had a receivable for federal income taxes if any.of $27 million, which was carried as a part of Other Assets. ProAssurance had a payable for federal income taxes of $20 million at December 31, 2012, which was carried as a part of Other Liabilities.
Except for the 2006 tax year, the statutes of limitation are closed for all years prior to 2008.2009. The statutestatutes for the 2006, tax year, as well as the 2009 and 2010 tax year, wasyears have been extended until September 30, 2014.
A reconciliation of the beginning and ending amounts of unrecognized tax benefits for 20122013 and 20112012 was as follows:

ProAssurance's provision for uncertain tax positions at both December 31, 2013 and December 31, 2012 and December 31, 2011 relatesrelated entirely to the timing of deductions. Changes to the provision recognized in current taxes during in 2012 and 2011 were offset by the recognition of a like but opposite change to deferred taxes. Unrecognized tax benefits at December 31, 20122013, if recognized, would not affect the effective tax rate but would accelerate the payment of tax. As with any uncertain tax position, there is a possibility that the ultimate deduction recognized could differ from the provision established by ProAssurance. Management does not expect any material changesAs the Company's uncertain tax positions relate to the Company’stiming of deductions, management expects the liability (other than interest accruals)to fully reverse during the next twelve months.
ProAssurance recognizes interest and/or penalties related to income tax matters in income tax expense. InterestNo interest was recognized in the income statement during the year ended December 31, 2013. Interest recognized during the years ended December 31, 2012 and 2011approximated $0.5 million, and $0.8 million and $0.4 million during the years ended December 31, 2012, 2011 and 2010, respectively. The accrued liability for interest approximated $1.41.3 million and $0.91.4 million at December 31, 20122013 and 20112012, respectively.

7. Deferred Policy Acquisition Costs
Policy acquisition costs, most significantly commissions, premium taxes, and underwriting salaries and benefits, that are primarily and directly related to the successful production of new and renewal insurance contracts are capitalized as policy acquisition costs and amortized to expense as the related premium revenues are earned.
As discussed in Note 1, revised FASB guidance effective January 1, 2012 requires thatAmortization of deferred policy acquisition costs related to unsuccessful contracts be expensed immediately. ProAssurance adoptedwas $59.1 million, $57.0 million and $59.6 million for the revised guidance on a prospective basis. Underyears ended December 31, 2013, 2012 and 2011, respectively.

7. Deferred Policy Acquisition Costs (continued)
prior guidance, policy acquisition costs capitalized during the year ended December 31, 2012, would have been $57.8 million as compared to $53.6 million capitalized under the current guidance.
Amortization of deferred policy acquisition costs was $57.0 million, $59.6 million and $58.9 million for the years ended December 31, 2012, 2011 and 2010, respectively.
8. Reserve for Losses and Loss Adjustment Expenses
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 internal actuaries to review the reserve for losses of each insurance subsidiary. ProAssurance also engages consulting actuaries to review ProAssurance claims data and provide observations regarding cost trends, rate adequacy and ultimate loss costs. ProAssurance considers the views of the 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 external actuary's certification as to their respective reserves in accordance with the requirements of the NAIC.
Activity in the reserve for losses and loss adjustment expenses is summarized as follows:

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 precise estimation, ProAssurance increases or decreases the reserve estimates established in prior periods. The favorable development recognized in 20122013 primarily reflects a lower than anticipated claims severity trend for accident years 20042005 through 2009.2011. The favorable development recognized in 20112012 and 20102011 was primarily due to lower than anticipated claims severity trends for accident years 2004 through 20082009 and accident years 20032004 through 20072008, respectively. Actuarial evaluations of both internal and industry actual claims data in 20122013, 20112012 and 20102011 all indicated that claims severity (i.e. the average size of a claim) is increasing more slowly than was anticipated when the reserves for 20032004 through 2009 were initially established.

9. Commitments and Contingencies
ProAssurance is involved in various legal actions related to insurance policies and claims handling including, but not limited to, claims asserted by policyholders. These types of legal actions arise in the Company’s ordinary course of business and, in accordance with GAAP for insurance entities, are considered as a part of the Company’s loss reserving process, which is described in detail under “Accounting Policies – Losses and Loss Adjustment Expenses” in Note 1.
ProAssurance has funding commitments primarily related to non-public investment entities totaling approximately $103.4164.2 million, expected to be paid as follows: $49.6 million in 2014, $60.168.9 million within one year,in 2015 and 2016 combined, $42.526.8 million within one to three years,in 2017 and 2018 combined, and $0.818.9 million within threethereafter.
As a member of Lloyd's and a capital provider to five years.Syndicate 1729 ProAssurance is required to provide capital, referred to as Funds at Lloyd's (FAL), to support Syndicate 1729. In order to meet these FAL requirements, ProAssurance, through a wholly owned subsidiary, provided a standby letter of credit (LOC) of £41.9 million ($69.3 million at December 31, 2013) and cash deposits of $8.7 million. At December 31, 2013 the LOC was fully secured by cash deposits, see Note 1. The LOC, unless earlier released by Lloyd's, expires four years from the date it is terminated or canceled. Any amounts advanced under the LOC will bear interest at prime plus 400 basis points or the highest legal rate for the borrowing. ProAssurance must pay a fee related to the LOC during the period it is outstanding, currently 50 basis points, which is to be re-determined annually based on ProAssurance’s then current credit standing and whether the LOC has been secured, with the maximum fee set at 188 basis points. No amounts have been drawn against the LOC at December 31, 2013.
ProAssurance has also issued an unconditional revolving credit agreement (the Credit Agreement) of up to £10 million ($17 million at December 31, 2013) to the Premium Trust Fund of Syndicate 1729 for the purpose of providing working capital. Advances under the Credit Agreement bear interest at 8.5% annually, and are repayable upon demand after December 31, 2016. As of December 31, 2013, £1.0 million ($1.7 million) had been advanced under the agreement.
ProAssurance is involved in a number of operating leases primarily for office space and office equipment. The following is a schedule of future minimum lease payments for operating leases that had initial or remaining non-cancelable lease terms in excess of one year as of December 31, 20122013.

ProAssurance is required to pay a commitment fee, ranging from 15 to 30 basis points based on ProAssurance’s credit ratings, on the average unused portion of the credit line during the term of the Agreement. The commitment fee can range from 15 to 30 basis points based on ProAssurance’s credit ratings and is set at 20 basis points at December 31, 2012.

The base rate selected may be the then current one, threeone-, three- or six monthsix-month LIBOR rate, with the LIBOR term selected fixing the interest period for which the rate is effective. If LIBOR is not selected, the base rate defaults to the highest of (1) the Prime rate (2) the Federal Funds rate plus 50 basis points or (3) the one month LIBOR rate plus 100 basis points, determined daily.

13. Variable Interest Entities (continued)
ProAssurance has not consolidated these VIE's because it has either very limited or no power to control the activities that most significantly affect the economic performance of these entities and is not the primary beneficiary of any of the entities. ProAssurance’s involvement with each entity is limited to its direct ownership interest in the entity. ProAssurance has no arrangements or agreements of significance with any of the entities to provide other financial support to or on behalf of the

entity. At December 31, 20122013, ProAssurance’s maximum loss exposure relative to these investments was limited to the carrying value of ProAssurance’s investment in the VIE.
14. Earnings Per Share
Diluted weighted average shares is calculated as basic weighted average shares plus the effect, calculated using the treasury stock method, of assuming that dilutive stock options have been exercised and that performance, restricted, and restrictedpurchase share units have vested.
Stock options are not dilutive when the option exercise price exceeds the average price of a common share during the period or when the result from assuming an option is exercised is a net decrease to outstanding shares. All outstanding stock options, wereperformance, restricted, and purchase share units had a dilutive effect for the years ended December 31, 2013, 2012 and 2011. During the year ended December 31, 2010, the average number of options not considered to be dilutive approximated 123,000.2011.
15. Benefit Plans
ProAssurance maintains a defined contribution savings and retirement plan (the ProAssurance Savings Plan) that is intended to provide retirement income to eligible employees. The plan provides for employer contributions to the plan of between 5% and 10% of salary for qualified employees. During 20112013 and 2010,2011, ProAssurance also maintained several similar plans of acquired entities prior to the plans being merged into the ProAssurance Savings Plan. ProAssurance incurred expense related to the savings and retirement plans of $5.19.8 million, $4.35.1 million and $4.44.3 million during the years ended December 31, 20122013, 20112012 and 20102011, respectively.
ProAssurance also maintains a non-qualified deferred compensation plan (the ProAssurance Plan) that allows participating management employees to defer a portion of their current salary. ProAssurance incurred expense related to the ProAssurance Plan of $0.2 million during each of the years ended December 31, 20122013, 20112012 and 20102011. ProAssurance deferred compensation liabilities totaled$13.1 million at December 31, 2013 and $11.1 million at December 31, 2012 and $11.5 million at December 31, 2011. The liabilities included amounts due under the ProAssurance Plan and amounts due under individual agreements with current or former employees, and amounts due under a currently inactive non-qualified plan.employees.
16. Statutory Accounting and Dividend Restrictions
ProAssurance’s insurance subsidiaries are required to file statutory financial statements with state insurance regulatory authorities, prepared based upon statutory accounting practices prescribed or permitted by regulatory authorities. ProAssurance did not use any prescribed or permitted statutory accounting practices that differed from the National Association of Insurance Commissioners' statutory accounting practices at December 31, 2013, 2012 or 2011. Differences between net income prepared in accordance with GAAP 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 recognized under GAAP but are not recognized for statutory purposes.
The NAIC specifies risk-based capital requirements for property and casualty insurance providers. At December 31, 20122013 actual statutory capital and surplus for each of ProAssurance’s insurance subsidiaries was sufficient to satisfysubstantially exceeded the regulatory requirements. Net earnings and capital and surplus of ProAssurance’s insurance subsidiaries on a statutory basis are shown in the following table. The table below includes the statutory earnings of APS for the statutory annual period of the year of acquisition and thereafter (see Note 2). Consolidated net income, on a GAAP basis, includes the earnings of APS only for the periods following acquisition (November 2010). The below table does not include Medmarc,Eastern, as the acquisition occurred on January 1, 20132014 (see Note 18).
