Forward-Looking Statements

Any statements in this Form 10-Q that are not historical facts are specifically identified as forward-looking statements. These statements are based upon our estimates and anticipation of future events and are subject to certain risks and uncertainties that could cause actual results to vary materially from the expected results described in the forward-looking statements. Forward-looking statements are identified by words such as, but not limited to, “anticipate”, “believe”, “estimate”, “expect”, “hope”, “hopeful”, “intend”, “likely”, “may”, “optimistic”, “possible”, “potential”, “preliminary”, “project”, “should”, “will” and other analogous expressions. There are numerous factors that could cause our actual results to differ materially from those in the forward-looking statements. Thus, sentences and phrases that we use to convey our view of future events and trends are expressly designated as forward-looking statements as are sections of this Form 10-Q that are identified as giving our outlook on future business.

Forward-looking statements relating to our business include among other things: statements concerning liquidity and capital requirements, investment valuation and performance, return on equity, financial ratios, net income, premiums, losses and loss reserves, premium rates and retention of current business, competition and market conditions, the expansion of product lines, the development or acquisition of business in new geographical areas, the availability of acceptable reinsurance, actions by regulators and rating agencies, court actions, legislative actions, payment or performance of obligations under indebtedness, payment of dividends, and other matters.

These forward-looking statements are subject to significant risks, assumptions and uncertainties, including, among other things, the following factors that could affect the actual outcome of future events:


•	changes in general economic conditions;


•	our ability to maintain our dividend payments;


•	regulatory, legislative and judicial actions or decisions that could affect our business plans or operations;


•	the enactment or repeal of tort reforms;


•	formation or dissolution of state-sponsored medical professional liability insurance entities that could remove or add sizable groups of physicians from or to the private insurance market;


•	the impact of deflation or inflation;


•	changes in the interest rate environment;


•	changes in U.S. laws or government regulations regarding financial markets or market activity that may affect the U.S. economy and our business;


•	changes in the ability of the U.S. government to meet its obligations that may affect the U.S. economy and our business;


•	performance of financial markets affecting the fair value of our investments or making it difficult to determine the value of our investments;


•	changes in accounting policies and practices that may be adopted by our regulatory agencies, the Financial Accounting Standards Board, the Securities and Exchange Commission or the Public Company Accounting Oversight Board;


•	changes in laws or government regulations affecting the financial services industry, the property and casualty insurance industry or particular insurance lines underwritten by our subsidiaries;


•	the effects of changes in the healthcare delivery system, including but not limited to the Patient Protection and Affordable Care Act;


•	consolidation of healthcare providers and entities that are more likely to self insure and not purchase medical professional liability insurance;


•	uncertainties inherent in the estimate of loss and loss adjustment expense reserves and reinsurance;


•	changes in the availability, cost, quality or collectability of insurance/reinsurance;


•	the results of litigation, including pre- or post-trial motions, trials and/or appeals we undertake;


•	allegation of bad faith which may arise from our handling of any particular claim, including failure to settle;


•	loss of independent agents;


•	changes in our organization, compensation and benefit plans;


•	our ability to retain and recruit senior management;

Table of Contents


•	assessments from guaranty funds;


•	our ability to achieve continued growth through expansion into other states or through acquisitions or business combinations;


•	changes to the ratings assigned by rating agencies to our insurance subsidiaries, individually or as a group;


•	provisions in our charter documents, Delaware law and state insurance law may impede attempts to replace or remove management or may impede a takeover;


•	state insurance restrictions may prohibit assets held by our insurance subsidiaries, including cash and investment securities, from being used for general corporate purposes;


•	taxing authorities can take exception to our tax positions and cause us to incur significant amounts of legal and accounting costs and, if our defense is not successful, additional tax costs, including interest and penalties;


•	insurance market conditions may alter the effectiveness of our current business strategy and impact our revenues; and


•	expected benefits from completed and proposed acquisitions may not be achieved or may be delayed longer than expected due to business disruption; loss of customers, employees and key agents; increased operating costs or inability to achieve cost savings; and assumption of greater than expected liabilities, among other reasons.

Additional risks that could adversely affect the merger of Medmarc Mutual Insurance Company, now Medmarc Casualty Insurance Company (Medmarc), Independent Nevada Doctors Insurance Exchange (IND), merged into ProAssurance Casualty Company effective October 1, 2013, and Eastern Insurance Holdings, Inc. (Eastern) into ProAssurance, include but are not limited to the following:


•	the outcome of any potential claims asserted by either the policyholders or shareholders of any of these acquired entities relating to payments or other issues associated with the acquisition of the entities and subsequent mergers into ProAssurance;


•	the businesses of ProAssurance and Medmarc, ProAssurance and IND or ProAssurance and Eastern may not be integrated successfully, or such integration may take longer to accomplish than expected;


•	cost savings from the transactions may not be fully realized or may take longer to realize than expected;


•	operating costs, customer loss and business disruption following one or all transactions, including adverse effects on relationships with employees, may be greater than expected;


•	there may be restrictions on our ability to achieve continued growth through expansion into other states or through acquisitions or business combinations;


•	governmental approvals of the Eastern merger may not be obtained or adverse regulatory conditions may be imposed in connection with governmental approvals of the merger;


•	the board of directors of Eastern may withdraw its recommendation and support a competing acquisition proposal; and


•	Eastern's shareholders may fail to approve the merger.

Our results may differ materially from those we expect and discuss in any forward-looking statements. The principal risk factors that may cause these differences are described in “Item 1A, Risk Factors” in our Form 10-K and other documents we file with the Securities and Exchange Commission, such as our current reports on Form 8-K, and our regular reports on Form 10-Q.

We caution readers not to place undue reliance on any such forward-looking statements, which are based upon conditions existing only as of the date made, and advise readers that these factors could affect our financial performance and could cause actual results for future periods to differ materially from any opinions or statements expressed with respect to future periods in any current statements. Except as required by law or regulations, we do not undertake and specifically decline any obligation to publicly release the result of any revisions that may be made to any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events.

Notes to Condensed Consolidated Financial Statements (Unaudited)

September 30, 2013

1. Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of ProAssurance Corporation and its consolidated subsidiaries (ProAssurance, PRA or the Company). The financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation, consisting of normal recurring adjustments, have been included. ProAssurance’s results for the three- and nine-month periods ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013. The accompanying Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Notes contained in ProAssurance’s December 31, 2012 report on Form 10-K. In connection with its preparation of the Condensed Consolidated Financial Statements, ProAssurance evaluated events that occurred subsequent to September 30, 2013 for recognition or disclosure in its financial statements and notes to financial statements.

Stock Split

In 2012, the Board of Directors of ProAssurance Corporation (the Board) declared a two-for-one 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.

Accounting Changes Not Yet Adopted

Liabilities-Obligations Resulting from Joint and Several Liability Arrangements

Effective for fiscal years beginning after December 15, 2013, the Financial Accounting Standards Board (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. The new guidance requires retrospective application to all prior periods presented for any such arrangements that exist 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.

Income Taxes-Presentation of Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists

Effective for fiscal years beginning after December 15, 2013, the FASB issued guidance related to the financial statement presentation of unrecognized tax benefits. The new guidance requires an entity to present unrecognized tax benefits as a reduction to a deferred tax asset resulting from a net operating loss carryforward, a similar tax loss, or tax credit carryforward except in circumstances where the relevant taxing authority does not permit offset or does not require offset and the entity does not intend to use the deferred tax asset for offset. The guidance requires prospective application for all unrecognized tax benefits that exist as of the effective date, but may be applied retrospectively. ProAssurance plans to adopt the guidance prospectively beginning January 1, 2014. Adoption of this guidance is expected to have no effect on ProAssurance's results of operations or financial position.

Accounting Changes Adopted

Intangibles-Goodwill and Other

Effective for fiscal years beginning after September 15, 2012, the 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.

All entities acquired in 2013 and 2012 were accounted for in accordance with GAAP relating to business combinations.

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. ProAssurance transferred all of the cash required to complete the transaction 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 $2.3 million during the first nine months of 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.

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.

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 $36.0 million, including $0.5 million recognized during the third quarter of 2013 due to the redetermination of pre-acquisition tax liabilities. 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.

Intangible assets acquired principally consist of non-compete agreements, which are amortizable over their useful life of two years, and insurance licenses, which have an indefinite useful life and are not amortized.

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 three and nine months ended September 30, 2013 and 2012 as if the Medmarc transaction had occurred on January 1, 2012. ProAssurance Actual Consolidated Results have been adjusted by the following, net of related tax effects, to reflect the Pro Forma Consolidated Results below.

•

For the three and nine months ended September 30, 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 three and nine months ended September 30, 2013 included Medmarc operating results (Revenue of $10.4 million and $33.2 million, respectively, and Earnings of $1.9 million and $6.4 million, respectively).


•	Certain costs included in ProAssurance actual results for the three and nine months ended September 30, 2013 have been reported in the Pro Forma Consolidated Results as if the costs had been incurred for the three and nine months ended September 30, 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 three and nine months ended September 30, 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 gain on the acquisition of $0.5 million and $36.0 million that was included in ProAssurance Actual Consolidated Results for the three and nine months ended September 30, 2013, respectively, has been reported in the Pro Forma Consolidated Results as being recognized during the three and nine months ended September 30, 2012.

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 measured at fair value on a recurring basis as of September 30, 2013 and December 31, 2012, 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 have been necessary in 2013 or 2012.

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 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. Valuations 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. Valuations of subprime home equity loans use the same valuation methodology as previously described for Alt-A mortgages.

Short-term investments included in the Level 2 category are commercial paper and certificates of deposit 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 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 discounted cash flow 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 September 30, 2013 and December 31, 2012 all of these bonds were rated A- or better.

Corporate debt with limited observable inputs consists of certain corporate bonds and, at December 31, 2012, private placement senior notes guaranteed by large regional 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 September 30, 2013, 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 consist of limited partnership (LP) and limited liability company (LLC) interests valued using the NAV provided by the LP/LLC, which approximates the fair value of the interest.

Such interests include the following:

(1)	The LP is structured to provide income and capital appreciation primarily through investments in senior secured debt. Redemptions are not allowed. Income and capital are to be periodically distributed at the discretion of the LP over an anticipated time frame that spans from 7 to 9 years.


(2)	The LP holds long equities of public international companies. Redemptions are allowed at the end of any calendar month with a prior notice requirement of 15 days and are paid within 10 days of the end of the calendar month of the redemption request.

(3)

The LP holds both long and short U.S. and North American equities, and targets absolute returns using a strategy designed to take advantage of event-driven market opportunities. Redemptions are allowed with a notice requirement of up to 45 days and are paid within 30 days of the redemption date, unless the redemption request is for 90% or more of the requestor’s capital balance. Redemptions at the 90% and above level will be paid at 90%, with the remainder paid after the LP’s annual audit.

(4)

Comprised of interests in two unrelated LP funds, each structured to provide capital appreciation through diversified investments in private equity, which can include investments in buyout, venture capital, mezzanine debt, distressed debt and other private equity-oriented LPs. One LP allows redemption by special consent; the other does not permit redemption. Income and capital are to be periodically distributed at the discretion of the LP over an anticipated time frame that spans from 4 to 7 years.

Transfers

There were no transfers between the Level 1 and Level 2 categories during the three and nine months ended September 30, 2013 or 2012.

Transfers shown in the preceding Level 3 Tables are as of the end of the period and were to or from Level 2, unless otherwise noted.

The transfers of Other investments reported in the Level 3 Tables for the nine months ended September 30, 2012 related to an interest in an LLC. 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 September 30, 2012.

All remaining transfers during the three and nine months ended September 30, 2013 and September 30, 2012 related to securities held for which the level of market activity for identical or nearly identical securities varies from period to period.

Fair Value Measurements - Level 3 Liabilities

The following tables present information for the three and nine months ended September 30, 2012 regarding liabilities for which ProAssurance had elected fair value treatment.

The 2019 Note Payable (the Note) and a related interest rate swap agreement (the Swap) were measured at fair value on a recurring basis during 2012 and 2011, 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 Swap 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 Note on an amortized cost basis and the Swap at fair value. Both the Note and the Swap 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.

Financial Instruments - Methodologies Other Than Fair Value

The following table provides the estimated fair value of our financial instruments that, in accordance with GAAP for the type of investment, are measured using a methodology other than fair value. All fair values provided fall within the Level 3 fair value category.



	September 30, 2013				December 31, 2012
(In thousands)	Carrying Value		Fair Value		Carrying Value		Fair Value
Financial assets:
BOLI	$	53,922	$	53,922	$	52,414	$	52,414
Investment in unconsolidated subsidiaries	144,934		142,460		87,310		91,528
Other investments	36,459		47,900		31,085		38,656
Other assets	15,396		15,396		11,400		11,385
Financial liabilities:
Revolving credit agreement	$	—	$	—	$	125,000	$	125,000
Other liabilities	12,623		12,570		12,130		12,085

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 and a non-controlling interest in a limited liability company. Fair values of investments in tax credit partnerships were 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 was estimated as the proceeds ProAssurance would receive upon liquidation of the LLC.

Other investments 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 were based on the NAVs provided by the LP/LLC managers. The estimated fair value of the FHLB common stock was based on the amount ProAssurance would receive if its membership were canceled, as the membership cannot be sold. The fair value of the annuity was the present value of the expected future cash flows discounted using a rate available in active markets for similarly structured instruments.

Other assets and Other liabilities primarily consisted of related investment assets and liabilities associated with funded deferred compensation agreements. Other assets also included a secured note receivable. Fair value of the note is based on the present value of the expected cash flows, discounted at market rates on the valuation date for secured notes receivable with similar credit standings and similar payment structures. Other liabilities also included certain contractual liabilities related to prior business combinations. Fair values of the funded deferred compensation assets and liabilities were based on the NAVs of the underlying securities. The fair values of the business combination liabilities were based on the present value of the expected cash flows, discounted at ProAssurance’s assumed incremental borrowing rate on the valuation date for unsecured liabilities with similar repayment structures.

The fair value of the revolving credit agreement was estimated based on the present value of expected future cash outflows under the agreement, discounted at rates available on the valuation date for similar debt issued by entities with a similar credit standing to ProAssurance.

Unconsolidated Subsidiaries

ProAssurance holds investments in unconsolidated subsidiaries, accounted for under the equity method. The investments include the following:



	September 30, 2013				Carrying Value

					$	189,590	$	121,049

* Unfunded commitments are included in the carrying value of tax credit partnerships, only.

Tax credit partnership 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 $63.6 million at September 30, 2013. ProAssurance's ownership percentage relative to the remaining tax credit partnership interests was less than 20%; these interests had a carrying value of $81.3 million at September 30, 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 targets absolute returns using a strategy designed to take advantage of event-driven market opportunities.

The Non-public equity funds hold diversified private equities and are structured to provide capital appreciation.

As of September 30, 2013, there were 872 debt securities (31.1% of all available-for-sale fixed maturity securities held) in an unrealized loss position representing 520 issuers. The single greatest unrealized loss position was approximately $0.5 million; the second greatest unrealized loss position was approximately $0.4 million. The securities were evaluated for impairment as of September 30, 2013.

September 30, 2013

As of December 31, 2012, there were 142 debt securities (5.7% of all available-for-sale fixed maturity securities held) in an unrealized loss position representing 131 issuers. The single greatest unrealized loss position approximated $0.6 million; the second greatest unrealized loss position approximated $0.2 million. The securities were evaluated for impairment as of December 31, 2012.

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 of the Notes to Consolidated Financial Statements included in ProAssurance's December 31, 2012 Form 10-K.

Fixed maturity securities held in an unrealized loss position at September 30, 2013, 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 September 30, 2013 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.

No significant impairment losses were recognized in the 2013 three- and nine-month periods. Significant impairment losses recognized during the 2012 three- and nine-month periods were as follows:


•	ProAssurance recognized impairment losses related to certain residential mortgage-backed securities during the first two quarters of 2012 because carrying values for those securities were greater than the future cash flows expected to be received from the securities.


•	ProAssurance recognized impairments related to corporate debt securities during the first quarter of 2012 because the credit standing of the issuers had deteriorated.

The following table presents a roll forward of cumulative credit losses recorded in earnings related to impaired debt securities for which a portion of the other-than-temporary impairment was recorded in Other Comprehensive Income.

5. Income Taxes

ProAssurance estimates its annual effective tax rate at the end of each quarterly reporting period which is used to record the provision for income taxes in the interim financial statements. The provision for income taxes is different from that which would be obtained by applying the statutory Federal income tax rate to income before taxes primarily because a portion of ProAssurance’s investment income is tax-exempt, because ProAssurance utilizes tax credit benefits transferred from tax credit partnership investments, and in 2013, because ProAssurance recognized a non-taxable gain related to an acquisition.

The IRS has concluded an examination of the 2009 and 2010 returns and has issued a Notice of Proposed Adjustment (NOPA) for these years which would increase our current tax liability by approximately $130 million. ProAssurance has begun the IRS appeals process and is unable to reliably predict the timing of the final resolution or the ultimate outcome. The contested issues affect only the timing of when certain expense items are deductible for tax purposes and resolution of the NOPA would have no effect on our recorded tax expense, exclusive of interest found to be due on past-due taxes, if any.

At September 30, 2013, ProAssurance had a receivable for federal income taxes of $45 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 2009. The statutes for the 2006, 2009 and 2010 tax years have been extended until September 30, 2014.

6. 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.

Amortization of deferred policy acquisition costs was $15.4 million and $43.2 million for the three and nine months ended September 30, 2013, respectively, and $14.0 million and $43.5 million for the three and nine months ended September 30, 2012, respectively.

7. 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 recognized favorable net loss development of $49.4 million and $141.0 million related to previously established reserves for the three and nine months ended September 30, 2013, respectively. The favorable net loss development reflected reductions in the Company's estimates of claims severity. Development recognized for the three and nine months ended September 30, 2013 principally related to the 2005 through 2011 accident years.

For the three and nine months ended September 30, 2012, ProAssurance recognized favorable net loss development of $50.0 million and $157.5 million, respectively, to reflect reductions in estimated claim severity principally for accident years 2004 through 2010.

8. 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 of the Notes to Consolidated Financial Statements in ProAssurance's 2012 Form 10-K.

ProAssurance has commitments primarily related to non-public investment entities totaling approximately $198.3 million, expected to be paid as follows: $18.3 million in 2013, $112.6 million in 2014 and 2015 combined, $35.4 million in 2016 and 2017 combined, and $32.0 million thereafter.

ProAssurance has entered into a definitive agreement with Eastern Insurance Holdings, Inc. (Eastern) (NASDAQ: EIHI) to acquire its outstanding common shares. The all-cash transaction has an estimated value of $205 million. The transaction is expected to close by January 1, 2014 and is subject to customary conditions, including regulatory and Eastern shareholder approval.

9. Long-term Debt

ProAssurance has a revolving credit agreement (the "Agreement"), which expires in 2016 and permits aggregate outstanding borrowings of up to $150 million at any time during the term of the Agreement. The interest rate on a borrowing is set at the time the borrowing is initiated or renewed, and is based on various factors including ProAssurance's credit rating, whether the borrowing is secured or unsecured, and the term of the benchmark interest rate selected (one, three, or six months). Repayment of a borrowing is permitted at the end of the selected interest rate term. ProAssurance had no outstanding borrowings under the Agreement as of September 30, 2013 and $125 million outstanding as of December 31, 2012. We maintained an outstanding balance under the Agreement of $125 million from December 31, 2012 to September 2013.

Covenant Compliance

The Agreement contains customary representations, covenants and events constituting default, and remedies for default. The Agreement also defines financial covenants regarding permitted leverage ratios and minimum net worth. ProAssurance is currently in compliance with all covenants.

Loss on Extinguishment

ProAssurance recognized a $2.2 million loss on extinguishment of debt during the third quarter of 2012 upon repayment of the Note Payable due February 2019, which was carried at fair value.

10. Shareholders’ Equity

At September 30, 2013 and December 31, 2012, ProAssurance had 100 million shares of authorized common stock and 50 million shares of authorized preferred stock. The Board has the authority to determine provisions for the issuance of preferred shares, including the number of shares to be issued, the designations, powers, preferences and rights, and the qualifications, limitations or restrictions of such shares. To date, the Board has not approved the issuance of preferred stock.

ProAssurance declared cash dividends of $0.25 per common share for each of the first three quarters of 2013, totaling $46.4 million, which included the third quarter dividend of $15.5 million that was paid in October 2013. ProAssurance declared cash dividends of $0.125 per common share for each of the first three quarters of 2012, totaling $23.0 million, which included the third quarter dividend of $7.7 million that was paid in October 2012. The liability for unpaid dividends was included in Other liabilities. No dividends were paid in first quarter 2013 because payment of the regular fourth quarter 2012 dividend was accelerated into December 2012.

At September 30, 2013, prior Board authorizations of $127.1 million for the repurchase of common shares or the retirement of outstanding debt remained available for use. ProAssurance repurchased approximately 175,000 shares, having a total cost of $8.0 million, during the nine months ended September 30, 2013 and did not repurchase any common shares during the nine months ended September 30, 2012.

Share-based compensation expense was $2.2 million and $6.9 million for the three and nine months ended September 30, 2013, respectively, and $1.3 million and $6.4 million for the three and nine months ended September 30, 2012, respectively. Related tax benefits were $0.8 million and $2.4 million for the three and nine months ended September 30, 2013, respectively, and $0.5 million and $2.2 million for the three and nine months ended September 30, 2012, respectively.

ProAssurance awarded approximately 39,000 restricted share units and 146,000 base performance share units to employees in February 2013. The fair value of each unit awarded was estimated at $46.97, equal to the market value of a ProAssurance common share on the date of grant. All awards are charged to expense as an increase to equity over the service period (generally the vesting period) associated with the award. Restricted share units and performance share units vest in their entirety at the end of a three-year period following the grant date based on a continuous service requirement and, for performance share units, achievement of a performance objective. Partial vesting is permitted for retirees. A ProAssurance common share is issued for each unit once vesting requirements are met, except that units sufficient to satisfy required tax withholdings are paid in cash. The number of common shares issued for performance share units varies from 75% to 125% of base awards depending upon the degree to which stated performance objectives are achieved. ProAssurance issued approximately 32,000 and 120,000 common shares to employees in February 2013 related to restricted share units and performance share units, respectively, granted in 2010. Shares issued for performance share units were awarded at the maximum level (125%).

ProAssurance issued approximately 41,000 and 19,000 common shares to employees in February 2013 and 2012, respectively, as bonus compensation, as approved by the Compensation Committee of the Board. The shares issued were valued at fair value (the market price of a ProAssurance common share on the date of award).

Other Comprehensive Income (Loss) (OCI)

For all periods presented, OCI was comprised of unrealized gains and losses arising during the period related to available-for-sale securities less reclassification adjustments for gains (losses) from available-for-sale securities, including reclassifications of non-credit impairment losses, recognized in current period net income, net of tax. At September 30, 2013 and December 31, 2012, accumulated other comprehensive income was comprised entirely of unrealized gains and losses from available-for-sale securities, including non-credit impairment losses previously recognized in OCI of $0.5 million and $0.9 million, respectively, net of tax. All tax effects have been computed using a 35% rate.

Amounts reclassified from accumulated other comprehensive income to net income during the three and nine months ended September 30, 2013 and 2012 included the following:



	Three Months Ended September 30						Nine Months Ended September 30
(In thousands)	2013			2012			2013			2012
Reclassifications from accumulated other comprehensive income to net income, available for sale securities:
Realized investment gains (losses)	$	2,403		$	3,675		$	8,638		$	8,348
Non-credit impairment losses reclassified to earnings, due to sale of securities or reclassification as a credit loss	—			—			(347		)	(201		)
Total amounts reclassified, before tax effect	2,403			3,675			8,291			8,147
Tax effect (at 35%)	(841		)	(1,286		)	(2,902		)	(2,851		)
Net reclassification adjustments	$	1,562		$	2,389		$	5,389		$	5,296

11. Variable Interest Entities

ProAssurance holds passive interests in a number of entities that are considered to be Variable Interest Entities (VIEs) under GAAP guidance. ProAssurance's VIE interests principally consist of interests in LPs/LLCs formed for the purpose of achieving diversified equity and debt returns. ProAssurance VIE interests carried as a part of Other Investments totaled $31.5 million at September 30, 2013 and $25.1 million at December 31, 2012. ProAssurance VIE interests carried as a part of Investment in Unconsolidated Subsidiaries totaled $26.5 million at September 30, 2013 and $33.7 million at December 31, 2012.

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 September 30, 2013, ProAssurance’s maximum loss exposure relative to these investments was limited to the carrying value of ProAssurance’s investment in the VIE.

12. 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 and restricted share units have vested. All outstanding stock options, performance share and restricted share units had a dilutive effect for the three- and nine-month periods ended September 30, 2013 and 2012.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

The following discussion should be read in conjunction with the Condensed 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 the heading “Forward-Looking Statements”, our actual financial condition and operating results could differ significantly from these forward-looking statements.

Critical Accounting Estimates

Our Condensed 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 for losses" or "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.

The estimation of long-tailed insurance losses is inherently difficult and is subject to 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, 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 any potential litigation may occur, general economic conditions and, for claims involving bodily harm, the trend of healthcare costs. Long-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 expected 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, supplemented to the extent necessary by relevant industry loss and exposure data.

Table of Contents

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. Actuarial methods used to evaluate Medmarc reserves included the Bornhuetter-Ferguson Method (Paid and Reported) and the Development Method (Paid and Reported) described in Item 2 of ProAssurance's 2012 Form 10K. The Adjusted Reported, Adjusted Paid, and the Expected Loss Methods, described below, were also used to evaluate Medmarc's reserves. We supplemented Medmarc data with relevant industry data where sufficient Medmarc historical data was not available. Approximately 85% of the reserves assumed in the Medmarc acquisition are products liability reserves and approximately 15% are professional liability reserves.

The Adjusted Reported and the Adjusted Paid Methods are 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.

The Expected Loss Method estimates ultimate loss amounts based on an expected ratio of losses per exposure, with the exposure measure often being premium. The expected ratio is then applied to the exposure measure to project ultimate losses for each accident year under evaluation.

Initial Reserve Estimates-Current Accident Year

Considerable judgment is required in both the pricing of our business and in establishing our initial reserves for any current accident year period. The targeted loss ratio in our pricing varies to some extent by jurisdiction, type of coverage and policy limits. For our physician professional liability business, which represents the majority of our premiums, we are, on average, targeting a 75% loss ratio. Due to the lack of available open or closed claims data for the current accident year period, we heavily rely on the loss assumptions used in pricing our business in making our initial estimate of physician professional losses for the current accident year period. For our physician business, we presently and have historically utilized loss ratios that are approximately 8 to 10 percentage points above the ratios we have targeted in our pricing for the current accident year. We believe this appropriately considers inherent risks associated with our physician professional rate development process and the historic volatility of medical professional liability (MPL) losses and produces a reasonable best estimate of the reserves required to cover actual ultimate losses. We follow the same practice in establishing initial loss reserves for our other professional liability lines. In the current environment this equates to an overall average initial loss ratio of approximately 85% for our professional liability business.

Severity is defined as the average cost of resolving claims and the severity trend is the increase, or decrease, in severity from period to period. Although we remain uncertain regarding the ultimate severity trend to project into the future for our MPL business, as discussed in following paragraphs, we have given consideration to observed lower loss costs for this business and reduced rates in recent years. For 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 MPL line) by approximately 17% from the beginning of 2006 to September 30, 2013.

Table of Contents

Consideration of Severity

The severity trend assumption is a key assumption for both pricing models and the 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 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. For our MPL business, which comprised 89% of our gross earned premium in the first nine months of 2013, our current pricing models assume 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 this business of 3.2 percentage points, based on current claim disposition patterns. 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 MPL 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 the long-tail and volatility, we are generally cautious in making changes to the severity assumptions within our pricing model. 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.

For the 2004 to 2009 accident years both our internal and consulting actuaries have observed an unprecedented reduction in the frequency of MPL 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 for this business. It has also made it more challenging to factor severity into the various actuarial methodologies we use to evaluate our reserves. 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, 85% of our MPL claims are resolved after eight years for a given accident year. Due to this long tail, it can take several years before we are able to determine what impact, if any, has resulted from the decline in frequency and whether the expected increase in severity will materialize.

Development of Prior Accident Year Reserves

We re-evaluate our previously established reserves each period based on our most recently available claims data and currently available industry trend information. Changes to previously established reserve estimates are recognized in the current period if management’s best estimate of ultimate losses differs from the estimate previously established. While management considers a variety of variables in determining its best estimate, in general, as claims age, our methodologies for estimating reserves give more weight to actual loss costs which, as a whole, continue to indicate that ultimate loss costs will be lower than our previous estimates. The development recognized in the first nine months of both 2013 and 2012 was primarily attributable to the favorable resolution of MPL claims during the period and an evaluation of established case reserves and paid claims data that indicated that the actual severity associated with the remaining MPL claims will aggregately be lower than we had previously estimated. The Critical Accounting Estimates discussion in our 2012 Form 10K and our discussion of acquired reserves, above, include additional information regarding the methodologies used to evaluate our reserves.

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 pre-tax income.

We recognized net favorable reserve development of $49.4 million and $141.0 million during the three and nine months ended September 30, 2013, respectively.

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.

Table of Contents

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. 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 program 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 their then-current financial strength, rating and 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 September 30, 2013, 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.

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 losses 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 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 September 30, 2013; however, 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. At September 30, 2013 the distribution of our investments based on GAAP fair value hierarchies (levels) was as follows:



	Distribution by GAAP Fair Value Hierarchy			September 30, 2013
	Level 1	Level 2	Level 3	Total Investments
Investments recorded at:
Fair value	9%	83%	2%	94%
Other valuations				6%
Total Investments				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

Table of Contents

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.

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 securities 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 September 30, 2013 interests valued using a fund-provided NAV totaled $44.7 million, or 1% 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 September 30, 2013 these investments had a carrying value of approximately $235.3 million, which represented approximately 6% of total investments, as shown in the following table. Additional information about these investments is provided in Notes 3 and 4 of the Notes to Condensed Consolidated Financial Statements.



(In thousands)	Carrying Value		GAAP Measurement Method

Investment in unconsolidated subsidiaries:
Investments in tax credit partnerships	144,934		Equity

Business owned life insurance	53,922		Cash surrender value

Total investments - Other valuation methodologies	$	235,315

Investment Impairments

We evaluate our investments on at least a quarterly basis for declines in fair value that represent other than temporary impairment (OTTI). We 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, 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;


•	the extent to which the decline in fair value is attributable to credit risk specifically associated with the security or its issuer;


•	our internal assessments and those of our external portfolio managers regarding specific circumstances surrounding a security, which can cause us to believe the security is more or less likely to recover its value than other securities 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 security 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. 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.

Table of Contents

Our investments in tax credit partnerships are evaluated for OTTI by comparing cash flow projections of the underlying projects generating the tax credits to our recorded basis, and by considering our ability to utilize the tax credits generated by the investments.

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 September 30, 2013 we have not determined that any amounts are unrecoverable.

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). 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. As of September 30, 2013, a valuation allowance has not been deemed necessary.

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 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 September 30, 2013, our liability for unrecognized tax benefits approximated $4.8 million, and related accrued 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, 2013, 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. 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 the first quarter of 2013 goodwill was reduced by $1.9 million related to the re-determination of the fair value of assets and liabilities associated with an acquisition completed in 2012, and no additional goodwill was recognized related to acquisitions completed in 2013.

Accounting Changes

We are not aware of any accounting changes not yet adopted as of September 30, 2013 that would have a material effect on our results of operations or financial position. Note 1 of the Notes to Condensed Consolidated Financial Statements provides additional detail regarding accounting changes.

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 September 30, 2013, we held cash and liquid investments of approximately $301.0 million outside our insurance subsidiaries that were available for use without regulatory approval. Our holding company also has $150 million available under a revolving credit agreement, as discussed in this section under the heading "Debt." During the nine months ended September 30, 2013 our insurance subsidiaries paid dividends of $118 million, including extraordinary dividends of $5 million. In addition, our insurance subsidiaries paid ordinary dividends of $180 million in October 2013, and, in aggregate, are permitted to pay additional dividends of approximately $21 million over the remainder of 2013 without the prior approval of state insurance regulators. The payment of any dividend requires prior notice to the insurance regulator in the state of domicile, and the regulator may prevent the dividend if, in its judgment, payment of the dividend would have an adverse effect on the surplus of the insurance subsidiary.

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 claim payments for those policies 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 cash flows of approximately $24.0 million and $61.4 million for the nine months ended September 30, 2013 and 2012, respectively.

Operating cash flows for the nine months ended September 30, 2013 and 2012 compare as follows:



(In millions)	Operating Cash Flow
Cash provided (used) by operating activities for the nine months ended September 30, 2012	$	61
Increase (decrease) in operating cash flows:
Decrease in premium receipts (1)	(28		)
Increase in payments to reinsurers (2)	(6		)
Decrease in losses paid, net of reinsurance recoveries (3)	14
Decrease in deposit contracts (4)	(5		)
Increase in Federal and state income tax payments (5)	(1		)
Net cash provided (used) by acquisitions (6)	(11		)
Cash provided (used) by operating activities for the nine months ended September 30, 2013	$	24


(1)	The reduction in premium receipts reflected lower premium volume written during the preceding twelve months exclusive of acquisitions.


(2)	Approximately $5 million of the increase in reinsurance payments is attributable to a higher volume of premiums ceded under quota share and fronting arrangements as discussed under the heading "Ceded Premiums Written."

(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 decrease in loss payments for the first nine months of 2013 primarily reflected a smaller number of claims resolved with large indemnity payments. We have not seen evidence in our loss data that suggests the decrease in loss payments for the nine-month period represents a change in loss trends and as such have not changed our loss assumptions for the current period.

(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, nor are they accounted for as reinsurance contracts, but rather are considered as deposits received or returned. These contracts do not constitute a significant business activity for us.

Table of Contents


(5)	The increase in net tax payments during 2013, primarily reflects the following:


•	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."


•	A $8.3 million decrease in the final tax payments made during 2013 for the prior fiscal year,


•	A $7.9 million decrease in estimated tax payments during 2013 for the current fiscal year.


(6)	Net cash used by acquisitions reflected the payments of transaction costs, loss payments made by the acquired companies related to prior accident years for which reinsurance recoveries have not yet been received, and normal expense payments of the acquired companies for which the timing of the payment differs from the recognition of the expense.

Operating cash flows for the nine months ended September 30, 2012 and 2011 compare as follows:



(In millions)	Operating Cash Flow
Cash provided by operating activities for the nine months ended September 30, 2011	$	106
Increase (decrease) in operating cash flows:
Decrease in premium receipts (1)	(8		)
Decrease in payments to reinsurers (2)	3
Increase in losses paid, net of reinsurance recoveries (3)	(32		)
Increase in deposit contracts (4)	5
Decrease in cash received for investments (5)	(9		)
Decrease in cash paid for other expenses (6)	10
Increase in Federal and state income tax payments (7)	(9		)

Cash provided by operating activities for the nine months ended September 30, 2012	$	61


(1)	The reduction in premium receipts reflected lower premium volume written during the preceding twelve months exclusive of acquisitions.


(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 the first nine months of 2012 primarily reflected a greater number of claims resolved with large indemnity payments, approximately $9 million of which was not yet recovered at September 30, 2012. The additional loss payments were not isolated to any one state or to any specific risk groups. We have not seen evidence in our loss data that suggests the increase in loss payments for the nine-month period represents a change in loss trends and as such have not changed our loss assumptions for the current period.

(4)


(5)	The decrease in cash received for investments reflected the decrease in net investment income as well as timing differences of interest receipts between periods.


(6)	The decrease in cash paid for other expenses was principally attributable to non-recurring payments of American Physicians Service Group, Inc. (APS) integration costs, primarily compensation-related, during 2011.

Table of Contents


(7)	The net increase in tax payments during 2012 was attributable to:


•	An increase in estimated tax payments for the current year of $1.2 million, and an increase in the final payments for the prior fiscal year of $7.4 million.


•	Federal tax refunds received in 2011 of $7.5 million.


•	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. The payments reduced tax liabilities recognized prior to January 1, 2011 and did not increase or decrease 2011 tax expense.


•	A reduction in state and other tax payments of $1.5 million.

Reinsurance

Taxes

In December 2012 we received a Notice of Proposed Adjustment (NOPA) from the IRS which disallows approximately $372 million of the combined 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. We believe that our loss and loss adjustment expense deduction was computed in a manner consistent with tax law, our past practices, and the practices of other liability insurers, and we have begun the IRS appeals process. 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, unless we are required to pay interest on past-due taxes, there would be no change to 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 reached with the IRS, or the extent, if any, to which we might be required to accelerate our tax payments or the amount of interest, if any, we might be required to pay. In January 2013 we made a $20.6 million protective tax payment to the IRS in order to reduce potential interest assessments.

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.

Table of Contents

A detailed listing of our investment holdings as of September 30, 2013 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 $50 million and $80 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 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. We repaid the borrowing during September 2013. Currently, $150 million of the credit facility is available for use. Given the 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 9 of the Notes to Condensed 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 September 30, 2013 was 3.9 years; the weighted average effective duration of our fixed maturity securities combined with our short-term securities and cash was 3.8 years. Net unrealized gains related to our fixed income securities decreased approximately $115.9 million during the nine months ended September 30, 2013. As interest rates have improved, the value of our fixed income securities has declined.

The carrying value of our equities portfolio increased $47.1 million during the nine months ended September 30, 2013. The fair value of the equity portfolio obtained from the acquisition of Medmarc was approximately $31.0 million. The remaining increase was primarily attributable to market appreciation.

The carrying value of our tax credit partnerships was approximately $144.9 million at September 30, 2013 and $87.3 million at December 31, 2012. Carrying value reflects 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. We funded approximately $58.8 million during the nine months ended September 30, 2013, and $29.5 million during the nine months ended September 30, 2012. Approximately $27.1 million and $20.5 million of our total commitments to the tax credit partnerships had not yet been funded as of September 30, 2013 and December 31, 2012, respectively.

The total carrying value of our investment fund LPs/LLCs was approximately $76.2 million at September 30, 2013 and $58.8 million at December 31, 2012, all of which has been funded. During the nine months ended September 30, 2013 and 2012, we funded investment LPs/LLCs, net of capital returned, in the amount of $8.4 million and $15.5 million, respectively. At September 30, 2013, we had total active commitments to investment fund LPs/LLCs of approximately $223.0 million, of which $171.2 million is unfunded. The unfunded 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 September 30, 2013 included investments of $133.2 million (3% of our total investments) where the issuer is domiciled in Europe or the underlying revenue stream supporting the security is European.

Our reinsurers typically operate globally and two of our largest reinsurers are domiciled in Europe. Many of our reinsurers have large investment portfolios which may be linked directly or indirectly to the European economy.

Acquisitions

On September 23, 2013, we entered into a definitive agreement with Eastern Insurance Holdings, Inc. (NASDAQ: EIHI) (Eastern) whereby ProAssurance will acquire all outstanding shares of Eastern for $24.50 per share. The all-cash transaction, with an aggregate value of approximately $205 million, is expected to close by January 1, 2014. Completion of the transaction is subject to customary conditions, including regulatory and Eastern shareholder approval.

Eastern is a holding company specializing in workers' compensation insurance and reinsurance products and services, including a segregated portfolio cell reinsurance business. Eastern presents financial information in three reportable segments: Workers' Compensation Insurance, Segregated Portfolio Cell Reinsurance, and Corporate/Other. The business of the Segregated Portfolio Cell Reinsurance segment is consolidated in Eastern's financial statements, however, certain of the cells are partially or wholly owned by unaffiliated entities, which reduces Eastern's ultimate premium retention. We have not completed our assessment with regards to Eastern and its impact, if any, on ProAssurance's reportable segments following the completion of the Eastern transaction. Summarized financial information regarding Eastern's operations follows:



(In thousands)	Nine Months Ended September 30, 2013		Year Ended December 31, 2012
Net premiums written, by segment:
Workers' Compensation	$	117,164	$	136,484
Segregated Portfolio Cell Reinsurance	32,234		33,474
Consolidated	$	149,398	$	169,958
Net premiums earned, by segment:
Workers' Compensation	$	105,955	$	127,499
Segregated Portfolio Cell Reinsurance	27,027		32,115
Consolidated	$	132,982	$	159,614
Net assets, consolidated	$	144,142	$	135,855

We acquired IND on November 30, 2012 through a conversion from a reciprocal exchange to a stock insurance company. IND, which had net earned premium for the 2012 calendar year of approximately $9.4 million, primarily provides medical professional liability insurance to physicians. We acquired Medmarc effective January 1, 2013 through a sponsored demutualization. Medmarc is an underwriter of products liability insurance for medical technology and life sciences companies and also underwrites a book of legal professional liability insurance. Medmarc had net earned premium for the 2012 calendar year of $30.0 million, of which $20.9 million related to medical technology and life sciences corporate liability coverages, and $9.1 million related to legal professional liability coverages. A $36.0 million gain was recognized on the acquisition of Medmarc as the estimated fair value of net assets acquired exceeded the purchase consideration given. Note 2 of the Notes to Condensed Consolidated Financial Statements provides additional information regarding acquisitions.

Financing Activities and Related Cash Flows

Treasury Shares

We repurchased approximately 175,000 common shares, having a cost of approximately $8.0 million, during the nine months ended September 30, 2013, all in the third quarter period. We did not repurchase any common shares during the nine months ended September 30, 2012. At September 30, 2013, approximately $127.1 million of Board authorizations for the repayment of debt or repurchase of common shares remained available for use.

Table of Contents

Shareholder Dividends

Our Board of Directors declared quarterly cash dividends of $0.25 per share in each of the first three quarters of 2013 and $0.125 per share in the same respective quarters of 2012. Dividends declared totaled $46.4 million during the first nine months of 2013 and $23.0 million during the first nine months of 2012. Our normal practice is to pay dividends in the month following the quarter in which they were declared. Payment of our fourth quarter 2012 dividend that would normally have been paid in January 2013 was accelerated and paid in December 2012. Consequently, dividends paid during the first nine months of 2013 of $30.8 million reflected payment of only two quarterly dividends, whereas dividends paid during the first nine months of 2012 of $22.9 million reflected payment of three quarterly dividends. Any decision to pay future cash dividends is subject to the Board’s final determination after a comprehensive review of financial performance, future expectations and other factors deemed relevant by the Board.

Debt

We have a revolving credit agreement (the "Agreement") that 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 into in the normal course of business. The Agreement expires in April 2016. As of December 31, 2012, we had an outstanding borrowing under the Agreement of $125 million, which remained outstanding until late September, 2013. During the first nine months of 2012, we repaid all then-outstanding long-term debt totaling $57.7 million, including a note payable that was carried at fair value. We recognized a loss on the repayment of the note payable of $2.2 million.

We are a member of a number of FHLBs. Through membership, we have access to secured cash advances which can be used for liquidity purposes or other operational needs. To date, we have not established a FHLB line of credit or materially utilized our membership.

ProAssurance is currently in compliance with all covenants associated with the revolving credit agreement. Additional information regarding our debt is provided in Note 9 of the Notes to Condensed Consolidated Financial Statements.

Overview of Results–Three and Nine Months Ended September 30, 2013 and 2012

Net Income and Operating Income



	Three Months Ended September 30				Nine Months Ended September 30
(In millions, except per share data)	2013		2012		2013		2012
Net income	$	63.4	$	60.1	$	226.7	$	174.2
Operating income	$	54.8	$	52.9	$	159.7	$	160.6

Net income per diluted share	$	1.02	$	0.97	$	3.65	$	2.82
Operating income per diluted share	$	0.88	$	0.86	$	2.57	$	2.60

Net income and operating income for both the three and nine months ended September 30, 2013 reflect higher earned premium and lower current accident year loss and tax ratios as compared to the same periods in 2012. The net favorable loss development recognized in 2013 was lower than amounts recognized in 2012 by $0.7 million for the comparative three-month periods and $16.6 million for the comparative nine-month periods. For the 2013 nine-month period, the effect of the lower favorable development on Net income was offset by a non-taxable gain on our acquisition of Medmarc of $36.0 million as well as greater amounts of net realized investment gains. Operating income is a non-GAAP financial measure and does not include net realized investment gains or the acquisition gain. A reconciliation of Operating income to Net income follows under the heading "Non-GAAP Financial Measures".

Results for the three and nine months ended September 30, 2013 and 2012 compare as follows:

Revenues

Net premiums earned increased during the 2013 three- and nine-month periods by approximately $6.5 million or 5.1% and $3.5 million or 0.9%, respectively. Our acquisitions of Medmarc and IND contributed $10.6 million and $30.7 million of additional net premiums earned during the 2013 three- and nine-month periods, respectively. In addition, reductions to ceded premium attributable to the favorable emergence of losses ceded to our reinsurers under the variable components of our reinsurance arrangements were approximately $3.7 million and $9.2 million greater for the 2013 three- and nine-month periods, respectively. These increases to net premiums earned were partially offset by premium losses attributable to non-renewals that were greater than premium gains from new business in 2013 and, for the nine-month period of 2013, a reduced amount of premium from tail policies.

Our net investment result (which includes both net investment income and earnings from unconsolidated subsidiaries) decreased $0.5 million or 1.6% and $2.0 million or 2.1% for the 2013 three- and nine-month periods, respectively. Net investment income decreased during the 2013 three- and nine-month periods primarily due to reduced earnings on our fixed income portfolio, partially offset by increased earnings from our equities portfolio and distributions received from a cost method investment LP in 2013. Earnings from unconsolidated subsidiaries decreased $0.5 million during the 2013 three-month period and increased $0.6 million in the 2013 nine-month period. For both the three- and nine-month periods of 2013 earnings from unconsolidated subsidiaries reflects increased amortization from our tax credit partnerships offset by stronger earnings from investment LPs.

Net realized investment gains in 2013 as compared to 2012 were approximately $0.7 million lower for the three-month period and approximately $25.3 million higher for the nine-month period. The increase for the nine-month period was principally attributable to an increase in our average equity trading portfolio investment and improved stock market yields. Impairments in 2013 were nominal for both the three- and the nine-month periods and were $0.1 million and $1.8 million for the 2012 three- and nine-month periods, respectively.

Expenses

The calendar year net loss ratio for the 2013 three-month period was 46.1%, a 1.6 percentage point increase as compared to 2012, and was 47.6% for the 2013 nine-month period, a 3.3 percentage point increase as compared to 2012. Both increases were principally attributable to the increase in earned premiums combined with lower favorable loss development in 2013 compared to 2012 by $0.7 million for the three-month period and $16.6 million for the nine-month period. Our current accident year net loss ratio decreased by 0.8 and 1.1 percentage points for the 2013 three- and nine-month periods, respectively, due to a reduction in ceded premiums related to prior accident years. Excluding this reduction, our current accident year net loss ratio increased by 1.8 and 1.1 percentage points for the 2013 three- and nine-month periods,

respectively, principally driven by higher estimates of unallocated loss adjustment expenses compared with the same periods in 2012.

Our underwriting expense ratio decreased 1.2 percentage points for the 2013 three-month period and increased 0.4 percentage points for the 2013 nine-month period. The expense ratio for both the quarter and year-to-date periods are impacted by a number of factors that potentially distort a run rate expense ratio. In particular, ceded premiums related to prior accident years and the effect of purchase accounting on the reported expenses of acquired companies lowered our ratio in 2013.

Operating Ratio and Return on Equity

Our operating ratio (calculated as our combined ratio, less our investment income ratio) increased by 1.7 and 4.6 percentage points in the 2013 three- and nine-month periods, respectively. The 2013 three-month increase primarily reflected a higher net loss ratio offset by a lower expense ratio, and a lower investment ratio. The 2013 nine-month increase reflected a higher net loss ratio, and a lower investment ratio.

Return on equity was 10.7% and 10.9% in the 2013 three- and nine-month periods, respectively, and 10.4% and 10.3% in the same respective periods of 2012. Our calculation of return on equity for the 2013 three- and nine-month periods excluded the effect of the $0.5 million and $36.0 million gain on acquisition, respectively.

Non-GAAP Financial Measures

Operating income is a non-GAAP financial measure that is widely used to evaluate performance within the insurance sector. In calculating operating income, we have excluded the after-tax effects of net realized investment gains or losses, guaranty fund assessments, loss on extinguishment of debt, gain on acquisition and the effect of 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.

The following table is a reconciliation of Net income to Operating income:

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, (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, and (4) the timing of premium written through multi-period policies. In addition, premium volume may periodically be affected by shifts in the timing of renewals between periods. The healthcare professional liability market remains competitive as a result of physicians joining hospitals or larger group practices and thus no longer purchasing insurance in the standard market. In addition, some competitors have chosen to compete primarily on price; both factors impact our ability to write new business and retain existing business.

Our retention rate for our standard physician business was approximately 89% for both the 2013 three- and nine-month periods, respectively, as compared to 89% and 90% for the same respective periods of 2012. 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 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.

The pricing of our renewed physician business averaged 1% higher than the expiring premiums during the 2013 three-month period and remained relatively flat during the 2013 nine-month period. The pricing of our business includes the effects of filed rates, surcharges and discounts. We continue to base our pricing 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.

Physician policies were our greatest source of premium revenues in both 2013 and in 2012. Excluding the effects of retention and renewal pricing discussed above, our 2013 twelve month term physician premium volume reflected the following:


•	In an effort to more evenly distribute the workload associated with renewals, we shifted policy renewals of $3.3 million from the third quarter of 2013 to the second quarter of 2013.


•	Certain policies with a twelve month term were renewed with a twenty-four month term during 2013. This contributed to the overall decrease by approximately $0.5 million and $2.5 million during the 2013 three- and nine-month periods, respectively. This change affects only the timing of renewals and will have no impact on earned premium.


•	Slightly offsetting the above decreases, IND contributed premiums of approximately $3.1 million and $8.3 million to the three- and nine-month periods, respectively.


•	In addition, we wrote new physician business of approximately $6 million and $13 million in the three- and nine-month periods, respectively.

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. For twenty-four month term policies, expiring premiums available for renewal in 2013 reflect policies written in 2011. When compared to expiring premium, our twenty-four month term premium decreased by $0.4 million for the three months ended September 30, 2013, while it increased by $2.2 million during the nine months ended September 30, 2013 primarily due to the renewal for twenty-four months of certain twelve month policies discussed above.

Our other healthcare providers are primarily dentists, chiropractors and allied health professionals. The increase in premium volume for these coverages during the 2013 three-month period primarily related to premium contributed by acquisitions and an improvement in new business and premium retention. The decline in premium volume for these coverages during the 2013 nine-month period was primarily attributable to the discontinuation of a program that offered coverage to optometrists.

Our healthcare facilities premium, which includes hospitals, surgery centers and other facilities, remained relatively flat in 2013.

Table of Contents

The increase in legal professionals premium for 2013 is principally attributable to our acquisition of Medmarc. Our legal professionals policies are offered throughout the United States, principally through agent and brokerage arrangements.

We offer extended reporting endorsement or “tail” coverage to insureds who discontinue their claims-made coverage with us, and we also periodically offer “tail” coverage through custom policies. The amount of tail coverage premium written can vary widely from period to period. The decrease in tail premium for the nine-month period of 2013 was principally due to a large single custom policy issued in the first quarter of 2012 for which there was no counterpart in 2013.

All medical technology and life sciences products liability premium is attributable to our acquisition of Medmarc. Our medical technology and life sciences products liability (products liability) business is marketed throughout the United States; coverage is offered on a primary basis, within specified limits, to manufacturers and distributors of medical technology and life sciences products.

Ceded premiums represent the amounts owed to our reinsurers for their assumption of a portion of our losses. In general we retain the first $1 million in risk insured by us and cede any coverages in excess of this amount. We pay our reinsurers a ceding premium in exchange for their accepting the risk, the ultimate amount of which is determined by the loss experience of the business ceded, subject to certain minimum and maximum amounts.

Ceded premiums for the three and nine months ended September 30, 2013 and 2012 compare as 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. In the second quarter of 2012, we projected (estimated) lower losses for the ceded coverages which reduced our estimate of the ceded premium for the current accident year. The nine months ended September 30, 2013 reflect those lower projections for the full period as compared to the same period in 2012, which only reflect lower losses in the second and third quarters. Additionally, certain products which were separately reinsured until October 1, 2012 are now included in our primary reinsurance arrangements at a lower cost than under their previous arrangements.


(2)	We share a portion of 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. Growth in the program increased ceded premium in the three and nine months ended September 30, 2013 as compared to the same respective periods of 2012.


(3)	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.


(4)	During the second quarter of 2013, we began a quota share arrangement under which we share the risk of loss with a captive insurer affiliated with one of our agents.

(5)

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 the three- and nine-month periods of 2013 we decreased the expected losses and associated recoveries for prior year ceded losses, and this in turn resulted in a decrease to our estimate of premiums ceded under these treaties. In the nine-month period of 2012 we reduced our estimate of premiums owed under reinsurance agreements for prior years. Decreases to estimates of premiums ceded related to prior accident years are fully earned in the period the change in estimates occur.


(6)	The business written by Medmarc and IND is reinsured under separate reinsurance arrangements.

Ceded Premiums Ratio

As shown in the table 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.



	Three Months Ended September 30						Nine Months Ended September 30
	2013		2012		Change		2013		2012		Change
Ceded premiums ratio, as reported	4.9	%	5.6	%	(0.7	)	7.5	%	7.3	%	0.2

Ratio, current accident year	7.1	%	5.6	%	1.5		10.2	%	8.0	%	2.2

The increase in the ceded premium ratio, current accident year, for the three- and nine-month periods ended September 30, 2013 as compared to the same periods in 2012 is attributable to the following:

Net Premiums Earned

Net premiums earned were as follows:



	Three Months Ended September 30											Nine Months Ended September 30
($ in thousands)	2013			2012			Change					2013			2012			Change
Gross premiums earned	$	144,280		$	137,050		$	7,230		5.3	%	$	428,784		$	423,065		$	5,719		1.4	%
Premiums ceded	(10,682		)	(9,925		)	(757		)	7.6	%	(30,256		)	(28,015		)	(2,241		)	8.0	%
Net premiums earned	$	133,598		$	127,125		$	6,473		5.1	%	$	398,528		$	395,050		$	3,478		0.9	%

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 twenty-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 changes to estimates of premiums owed under reinsurance agreements are fully earned in the period of change.

Gross premiums earned for both the 2013 three- and nine-month periods reflected additional premiums contributed by acquisitions of approximately $13.9 million and $40.3 million, respectively, offset by the pro-rata effect of lower physician premiums written by our other subsidiaries during the preceding twelve months, and a decline in tail premium of $8.0 million for the nine-month period. Our 2013 gross earned premium for the three- and nine-month periods includes approximately $4.2 million and $23.7 million, respectively, in gross earned premium 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 earned premium of approximately $1.4 million in the fourth quarter of 2013, and approximately $3.0 million in 2014 and beyond.

The increase in premiums ceded during the 2013 three- and nine-month periods reflected contributions from our acquisitions of approximately $3.3 million and $9.6 million, respectively. Our Ascension and fronting arrangements also contributed to the increase in premiums ceded for the 2013 three- and nine-month periods. These increases were partially offset by a greater ceded premium reduction related to prior accident years in 2013 as compared to 2012.

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.

Net investment income by investment category was as follows:

Fixed Maturities

The decrease in our income from fixed maturity securities was primarily due to lower average investment balances (exclusive of acquisitions) as compared to 2012. Although we added fixed securities valued at $314 million to our portfolio in 2013 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 securities was approximately 2% lower for both the three- and the nine-month periods of 2013 as compared to the same periods in 2012.

Average yields for our fixed maturity portfolio were generally lower in 2013, as shown in the table below.



	Three Months Ended September 30		Nine Months Ended September 30
	2013	2012	2013	2012
Average income yield	3.7%	3.9%	3.7%	3.9%
Average tax equivalent income yield	4.3%	4.5%	4.3%	4.5%

Yields on fixed maturity securities acquired in the Medmarc and IND transactions were lower than our average yield in 2012, which reduced our 2013 average consolidated tax equivalent yield by approximately 14 and 16 basis points for the three- and nine-month periods, respectively. 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 increased in the 2013 three- and nine-month periods as compared to the same periods in 2012 due to average investment balances that were approximately 53% and 74% higher in 2013, respectively. Given 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 allocation to dividend yielding equities and other non-fixed income investments.

Short-term Investments and Other Invested Assets

The increased income from our short-term investments and other invested assets for the 2013 three- and nine-month periods principally reflects distributions received from an interest in a LP that we account for using the cost method. No distributions were received from this investment in 2012.

Equity in Earnings (Loss) of Unconsolidated Subsidiaries

Equity in earnings (loss) of unconsolidated subsidiaries is derived from our investment interests accounted for under the equity method. Results were as follows:



	Three Months Ended September 30									Nine Months Ended September 30

Equity in earnings (loss) of unconsolidated subsidiaries	$	(305	)	$	211		$	(516	)	$	(3,500	)	$	(4,082	)	$	582

We hold interests in certain LPs that generate earnings from trading portfolios, secured debt, and private equity investments. The improved results for 2013 principally reflect higher earnings from a private equity LP.

Our business LLC interest was a non-controlling interest in a startup entity, which produced operating losses in 2012. We dissolved our interest in the entity during 2013.

Our tax credit investments are designed to generate returns by providing tax benefits 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 becomes 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 the third quarter of 2012 that were attributable to the re-estimation of inception-to-date amortization of certain partnership interests.

The tax benefits received from our tax credit partnerships, which are not reflected in our investment results above, reduced our tax expenses in 2013 and 2012 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 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-forma tax-equivalent result by estimating the amount of fully-taxable income needed to achieve the same after-tax result as is currently provided by our tax-preferred investments. We believe this better reflects the economics behind 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.

All impairments of debt securities recognized during 2013 and 2012 were credit-related.

The impairment recognized as part of Other investments during the nine months ended September 30, 2012 related to an interest in an LLC which we accounted for using the cost method. We impaired the investment to the NAV reported by the fund during the first quarter of 2012 because the fund was in the process of converting to a public fund. The conversion occurred during the second quarter of 2012.

The loss on sales of available-for-sale securities of $5.3 million realized during the third quarter of 2013 was entirely related to sales of fixed maturity securities and included fixed maturity securities held in an unrealized loss position of approximately $3.8 million at June 30, 2013. The decision to sell the securities was made subsequent to the filing of our June 30, 2013 Form 10Q, and was made principally as a result of finalizing the agreement to acquire Eastern. As of the date of filing of our June 30, 2013 Form 10Q, there was no intent to sell these securities nor was it more likely than not that the securities would be required to be sold before recovery of their amortized cost basis. Additionally, the unrealized loss on the securities as of June 30, 2013 was a low percentage of the amortized cost basis of the securities (approximately 3% on average) and the securities had not been identified as having suffered a deterioration in credit quality.

We substantially increased the size of our equity trading portfolio during the first quarter of 2013 and last three quarters of 2012. Unrealized trading portfolio gains in the nine-month period of 2013 reflected both higher average balances and improved stock market valuations in 2013 as compared to 2012.

Gains (losses) from changes in the fair value of liabilities in 2012 were entirely attributable to our 2019 Note Payable and related interest rate swap, both of which we repaid in July 2012.

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.

Table of Contents

The following table summarizes calendar year net loss ratios by separating losses between the current accident year and all prior accident years. Additionally, the table shows our current accident year net loss ratio was significantly affected by revisions to our estimate of premiums owed to reinsurers related to coverages provided in prior accident years. Our current accident year net loss ratios for the three and nine months ended September 30, 2013 and 2012 compare as follows:



	Net Loss Ratios (1)
	Three Months Ended September 30						Nine Months Ended September 30
	2013		2012		Change		2013		2012		Change
Calendar year net loss ratio	46.1	%	44.5	%	1.6		47.6	%	44.3	%	3.3
Prior accident year net loss ratio	(37.0	%)	(39.4	%)	2.4		(35.4	%)	(39.8	%)	4.4
Current accident year net loss ratio, as reported	83.1	%	83.9	%	(0.8	)	83.0	%	84.1	%	(1.1	)
Estimated ratio increase (decrease) attributable to:
Ceded premium reductions, prior accident years (2)	(2.6	)%	—	%	(2.6	)	(2.9	)%	(0.7	)%	(2.2	)
Current accident year net loss ratio, less listed effect	85.7	%	83.9	%	1.8		85.9	%	84.8	%	1.1


(1)	Net losses as specified divided by net premiums earned.


(2)	Net earned premium in the three- and nine-month periods of 2013 and in the nine-month period of 2012 was increased by reductions to premiums owed under reinsurance agreements for prior accident years (see the discussion under the heading "Ceded Premiums Written"). The reductions were greater in 2013 and had a more significant effect on the net loss ratio than in 2012.

The increase in the current accident year net loss ratio, shown above, for the three and nine months ended September 30, 2013 as compared to the same periods in 2012 is attributable to the following:



	Increase (decrease), 2013 versus 2012
	Comparative three-month periods		Comparative nine-month periods
Effect on current accident year net loss ratio from:
Tail coverages (1)	(0.1	)	(0.4	)
Acquisitions (2)	(1.2	)	(0.7	)
Increased unallocated loss adjustment expenses	3.3		3.3
Other	(0.2	)	(1.1	)
Net change in ratio	1.8		1.1


(1)	Our average net loss ratio was increased in the three- and nine-month periods of both 2013 and 2012 due to tail coverages because we expected higher losses for these coverages than for our other professional liability coverages; however, the effect was smaller in 2013 due to less earned premium from tail coverages as compared to 2012.


(2)	Loss ratios associated with the business we acquired from Medmarc and IND, particularly the products liability business, were lower than the average for our other business, which decreased our average current accident year net loss ratio for the three- and nine-month periods of 2013 as compared to the same periods of 2012.

During the three and nine months ended September 30, 2013 we recognized favorable loss development related to previously established reserves, on a gross basis, of $54.6 million and $158.1 million, respectively. On a net basis, we recognized favorable development of $49.4 million and $141.0 million for three and nine months ended September 30, 2013, respectively. The net basis reflects favorable development recognized with respect to our ceded coverage layers. We re-evaluate our previously established reserves each quarter based on our most recently available claims data and currently available industry trend information. As discussed in our Form 10Q for the period ended March 31, 2013, given our increasing confidence in the underlying loss trends we recognized $53.1 million of favorable development in the first quarter of this year. Based upon additional observations coming out of our more detailed review performed during the second quarter of 2013 we recognized a lower level of favorable development for the second quarter of 2013, and increased our reserve estimate for losses in excess of policy limits, for a total net favorable development of $38.5 million. Observations coming out of our third quarter review of claims data indicated no further deterioration in the particular reserve components that were of concern during the

Table of Contents

second quarter of 2013. Furthermore, based on legal developments during the third quarter, we have lowered our estimate for losses in excess of policy limits as of September 30, 2013.

Development recognized for the 2013 three- and nine-month periods principally related to accident years 2005 through 2011. We have not recognized any development in 2013 related to the reserves acquired from Medmarc and IND.

We recognized net favorable loss development of $50.0 million and $157.5 million related to our retained layers of coverage during the three and nine months ended September 30, 2012, respectively, primarily related to accident years 2004 through 2010. A detailed discussion of factors influencing our recognition of loss development recognized is included under "Critical Accounting Estimates - Reserve for Losses and Loss Adjustment Expenses.”

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 2013 and 2012.

Underwriting, Policy Acquisition and Operating Expenses

The table below provides a comparison of the three and nine months ended September 30, 2013 and 2012 underwriting, policy acquisition and operating expenses:

The following table highlights the items affecting expenses in 2013 and 2012.

Higher compensation costs during 2013, principally attributable to incentive compensation	0.8			3.0
Increase in compensation costs allocated to ULAE or capitalized as deferred policy acquisition costs during 2013	(2.3		)	(6.3		)
Amortization of deferred policy acquisition costs reflects a reduction in 2013 attributable to lower premium volume and, for the nine-month period, a reduction attributable to the adoption of new accounting guidance at the beginning of 2012. The effect of lower premium volume was offset in the 2013 three-month period and somewhat offset in the 2013 nine-month period by underwriting compensation costs which were higher in 2013 than in 2012.	—			(2.8		)
Variances attributable to discrete events of 2013 or 2012:
Medmarc and IND transaction-related costs, principally professional fees and one time compensation costs	(0.6		)	1.8
Compensation costs associated with employee relocation and severance, principally related to the enhancement of our customer service capabilities in 2012	—			(0.7		)
Recoveries received in 2012 related to the settlement of litigation	—			0.7
Other variations not individually significant	(0.7		)	(1.2		)
Net change in expenses	$	0.1		$	2.5


*	The impact of purchase accounting related to deferred policy acquisition costs reduced the reported expenses by approximately $0.8 million and $4.2 million for the 2013 three- and nine-month periods, respectively.

Underwriting Expense Ratio (the Expense Ratio)

Our expense ratio was affected in both 2013 and 2012 by ceded premium reductions related to prior accident years, as discussed under the heading "Ceded Premiums Written", and by expenses associated with discrete events (see table above):



	Underwriting Expense Ratio
	Three Months Ended September 30						Nine Months Ended September 30
	2013		2012		Change		2013		2012		Change
Underwriting expense ratio, as reported	25.0	%	26.2	%	(1.2	)	26.5	%	26.1	%	0.4
Estimated ratio increase (decrease) attributable to:
Ceded premium reductions, prior accident years	(0.7	%)	—	%	(0.7	)	(0.7	%)	(0.2	%)	(0.5	)
Expenses associated with discrete events (see table above)	0.3	%	0.8	%	(0.5	)	0.7	%	0.3	%	0.4
Underwriting expense ratio, less listed effects	25.4	%	25.4	%	—		26.5	%	26.0	%	0.5

As compared to 2012, our 2013 underwriting expense ratio was also affected by the following:



	Increase (decrease), 2013 versus 2012
	Comparative three-month periods		Comparative nine-month periods
Estimated ratio increase (decrease) attributable to:
Lower net earned premiums, exclusive of acquisitions	0.8		1.4
Acquisitions, see discussion below	0.3		—
Increased compensation costs	0.6		0.7
Increase in costs allocated to ULAE or capitalized as deferred policy acquisition costs	(1.7	)	(1.5	)
Other	—		(0.1	)
Net increase/(decrease) in ratio	—		0.5

The operating expenses of Medmarc and IND, exclusive of transaction costs, had a minor effect on our 2013 ratio as these entities also increased net premium earned. However, as previously discussed, recorded deferred policy acquisition cost amortization for these entities was lower in 2013 than would be considered normal due to the application of GAAP purchase accounting rules. Normalizing these costs would increase our ratio for the 2013 three- and nine-month periods by approximately 0.6 and 1.0 percentage points, respectively.

Interest Expense

Interest expense declined during the three and nine months ended September 30, 2013 as compared to the same periods in 2012 reflecting higher average outstanding debt in 2013 but a lower average rate. Our weighted average outstanding debt under our revolving credit agreement approximated $123 million for the nine months ended September 30, 2013. No amount was outstanding under the credit agreement in the first nine months of 2012, although fees and amortization were incurred. Our average outstanding debt under all other long term debt instruments (all retired third quarter 2012) approximated $40 million for the nine months ended September 30, 2012.

Interest expense for the three and nine months ended September 30, 2013 and 2012 is provided in the following table:



	Three Months Ended September 30							Nine Months Ended September 30

Taxes

Factors affecting our effective tax rate include the following:



	Three Months Ended September 30				Nine Months Ended September 30
	2013		2012		2013		2012
Statutory rate	35.0	%	35.0	%	35.0	%	35.0	%
Tax-exempt income	(4.1	%)	(3.8	%)	(5.3	%)	(4.9	%)
Tax credits	(5.2	%)	(2.9	%)	(6.9	%)	(3.7	%)
Non-taxable gain on acquisition	(0.5	%)	—	%	(2.9	%)	—	%
Other	1.7	%	(0.2	%)	1.0	%	0.5	%
Effective tax rate	26.9	%	28.1	%	20.9	%	26.9	%

We estimate our annual effective tax rate at the end of each quarterly reporting period, which is used to record the provision for income taxes in our interim financial statements. Our effective tax rates for both the three- and nine-month periods of 2013 and 2012 were different from the statutory Federal income tax rate primarily because a portion of our investment income and the 2013 gain on acquisition are not taxable and because we utilized tax credit benefits transferred from our tax credit partnership investments.

Tax benefits recognized, related to the tax credits, approximated $4.5 million and $13.4 million for the three and nine months ended September 30, 2013, respectively, as compared to $2.5 million and $7.6 million for the 2012 three- and nine-month periods, respectively.

ITEM 3. 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 September 30, 2013 and December 31, 2012. 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.

Table of Contents

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’s cash and short-term investment portfolio at September 30, 2013 was carried on a cost basis which approximates its fair value. This 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 September 30, 2013, 93% of our fixed maturity securities were rated investment grade as determined by Nationally Recognized Statistical Rating Organizations (NRSROs), such as 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 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 $257 million at September 30, 2013 and $196 million at December 31, 2012, 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 September 30, 2013 the fair value of our investment in common stocks was $250 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 0.95. Beta measures the price sensitivity of an equity security or group of equity securities to a change in the broader equity market, in this case the S&P 500 Index. If the value of the S&P 500 Index increased by 10%, the fair value of these securities would be expected to increase by 9.5% to $273 million. Conversely, a 10% decrease in the S&P 500 Index would imply a decrease of 9.5% in the fair value of these securities to $226 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 4. CONTROLS AND PROCEDURES.

The Chief Executive Officer and Chief Financial Officer of the Company participated in management’s evaluation of our disclosure controls and procedures (as defined in SEC Rule 13a-15(e)) as of September 30, 2013. ProAssurance’s disclosure controls and procedures are designed to reasonably assure that information required to be disclosed by us in reports we file or submit under the Exchange Act is accumulated and communicated to our management as appropriate to allow timely decisions regarding disclosure and is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are effective.

Changes in Internal Control over Financial Reporting

There have been no significant changes in our internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, those controls during the quarter. On January 1, 2013 we completed the acquisition of Medmarc Mutual Insurance Company, now Medmarc Casualty Insurance Company (Medmarc). Our management has concluded that it will exclude 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 will not have completed our assessment of Medmarc's systems and processes by that date.

PART II. OTHER INFORMATION

See Note 8 of the Notes to Condensed Consolidated Financial Statements.

ITEM 1A. RISK FACTORS.

With the exception of the risk factor listed below, there are no changes to the “Risk Factors” in Part 1, Item 1A of the 2012 Form 10-K.

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.

The following table presents the claims paying ratings of our core insurance subsidiaries as of October 25, 2013. NR indicates that the subsidiary has not been rated by the listed rating agency.

Four rating agencies evaluate and rate our ability to service current debt and potential debt. These financial strength ratings reflect each agency’s independent evaluation of our ability to meet our obligation to holders of our debt, if any. While these ratings may be of greater interest to investors than our claims paying ratings, these are not ratings of our equity securities nor a recommendation to buy, hold or sell our equity securities.
