Every policy, every share of stock  
represents a promise.

Our business is a series of promises. And since 1975, 

ProAssurance has delivered on those promises by  

ensuring that our company remains financially strong, 

by managing our business for the long-term, and by 

treating fairly everyone with whom we come in  

contact. For 36 years, we’ve kept our promises. And  

we are managing our business today to keep our 

promises long into the future.

Promises are made to be kept

I believe promises are made to be kept. 

All too often, “I promise” is a simple statement, said without thought or written without intent. 

This is not so at ProAssurance. My colleagues and I believe in the true value of a promise made—
and we do not make any of our promises without duly considering what it takes to keep them.

For our investors, the promise we honor is one to manage ProAssurance in a way that increases 
the value of the investment we share. In 2010, we delivered on that promise and achieved excep-
tional results by virtually every measurement.

We again grew Book Value per Share by a double-digit percentage. We began the year with a 

Book Value per Share of $52.59, and ended 2010 at $60.35, an increase of 15%. As long-time 

For our investors, the promise we 
honor is one to manage ProAssurance 
in a way that increases the value of 
the investment we share. 

investors will know, we focus on Book Value per Share because 
it is an easily computed and easily comparable result that allows 
us to demonstrate to you the ultimate success of our efforts.
We increased the value of the Company by 9% in 2010, 
growing Shareholders’ Equity by $151 million to almost $1.9 

billion. We also achieved a Return on Equity of 13% in 2010.

We enhanced these key measurements through the prudent repurchase of 1.9 million shares  
of our common stock at a cost of $106 million. As part of our ongoing commitment to effectively 
manage our capital, we have purchased six million shares at a cost of $315 million since 2005.

During that five year period, efficient capital management has allowed us to enhance the value 
of ProAssurance for shareholders while growing the Company through six transactions that solidify

TO MY FELLOW SHAREHOLDERS:our present business and lay the foundation for future 
success. At the same time, our demonstrated commitment 
to capital adequacy has led rating agencies to upgrade our 
insurance subsidiaries to levels that clearly highlight the 
financial stability underlying our insurance products.

The financial success that has rewarded our investors 
with a compound annual growth rate of 16% since going 
public in 1991 has allowed us to build a balance sheet that 
permits us to keep our promise of insurance in a manner 
unlike any of our competitors. No company that I am aware 
of provides a product quite like the promise of service and 
security we deliver to our insureds. Certainly every company 
with which we compete provides its insureds with a policy, 
but the services provided through those policies and by the 
company behind the policies are vastly different.

Every day, we leverage the strength of our balance sheet 

to provide our insureds with a range of effective services 
that I believe are unmatched in our industry. I’m confident 
that ProAssurance’s embrace of cutting edge risk manage-
ment programs and content delivery methods is enhancing

Managing for the long term

The only way to survive in our 
specialty insurance market is through 
strict commitment to underwriting 
standards. Over the years, we’ve 
seen countless companies suffer 
the consequences of lax standards 
in pursuit of top-line growth. At 
ProAssurance, we manage for the 
long term to ensure that we have the 
financial strength to keep our promises 
to every insured–no matter when  
they might need us.

patient care and reducing the exposure of our insureds to frivolous litigation. I am equally certain 
that our ability to apply rigorous underwriting standards to the risks we accept allows ProAssurance 
to offer a superior product to the most qualified insureds.

But our ability to defend our insureds from a position of financial strength may be the most 
defining characteristic of ProAssurance. Simply stated, we deliver every day on the promise to give 
our insureds a defense of their claim that is unfettered by constraints unwisely imposed in the name 
of short-term profit. This dedication to the needs of our insureds creates a virtuous circle that furthers 
our continued ability to attract new customers who understand the true value and promise we pro-
vide, while retaining existing customers who understand the true value proposition of ProAssurance. 
In 2010, we retained 90% of our premium base in one of the most competitive market environments 
we’ve seen in the past decade. The fact that our superior product can rarely be sold at a price that 
matches policies offering inferior security and service makes this achievement all the more remarkable.
The value that our insureds perceive in the ProAssurance product and our investors realize in the 
increasing value of their stock is encapsulated in the brand promise of Treated Fairly. In each letter I’ve 
written to you since 2008, I have underscored the value of Treated Fairly, the guiding principle that 
governs every encounter with every constituent, internal and external, at ProAssurance. Treated Fairly 
is the ultimate promise we can make as a company, and it’s one that I, and everyone at ProAssurance, 
will do everything we can to keep.

Inherent in our commitment to both insureds and investors is the promise to adapt quickly and 
effectively to deal with the new realities of medicine and the delivery of healthcare. Few environments 
are evolving as rapidly—and as thoroughly—as the medical/legal environment in which the majority 
of our policyholders practice and, here again, we are able to bring our financial strength, operational 
expertise, and unmatched geographic reach to provide solutions to problems that our competitors 
simply cannot solve.

The demographics of healthcare have undergone a seismic shift in the past generation, and 
the consequences are becoming more evident every day. Fully 50% of the physicians practicing in 
America today are employed or affiliated with hospitals or large, 
multi-specialty groups. This migration to a more predictable 
practice setting is driven by a host of factors: the prevalence of 
physicians who seek more predictable working conditions, the 
enhanced insurance/government reimbursement for procedures 
performed by hospital-employed physicians, and the expense and 

Our ability to defend our insureds 
from a position of financial  
strength may be the most defining 
characteristic of ProAssurance. 

hassle of coping with federally mandated electronic documentation.

Yet despite common goals of these integrated physician/hospital systems, each approaches its 
professional liability risk with a different set of demands and expectations. ProAssurance has insured 
physicians for 35 years and hospitals for 25 years and is uniquely qualified to deliver the specialized 
insurance programs that allow both types of insured—entities and individuals—to address their own

requirements. As changes in healthcare push institutions  
to seek ways to use their scarce financial resources more  
effectively, ProAssurance is ready with effective solutions.
There are, however, and will always be, entrepreneurial 
physicians who crave the independence and challenge of solo 
and small group practice, and for them we are enhancing our 
traditional products to deal with emerging risks few could 
have imagined even five 
years ago. For example, we 
are embarking on a new 
specialty-specific program 

This promise of responsive,  
innovative, and secure insurance is 
a promise we do not make lightly. 

targeting the unique liability demands in the practice of 
obstetrics. We believe this will help us reach new insureds in 
markets where we are already doing business and in attractive 
new markets where our primary writings are currently con-
fined to our podiatric business.

This promise of responsive, innovative, and secure 
insurance is a promise we do not make lightly. The manage-
ment team at ProAssurance is the most experienced in our 
industry, and our past experience has prepared us to keep 
these far-reaching promises. Our level of investment in the 
Company ensures that we will take these promises—to  
investors and insureds alike—seriously.

We have achieved impressive results by maintaining our 
focus and discipline. The promise we make to you is that we 
will continue to apply those principles in what is sure to be an 
exciting future. We believe keeping that promise will allow us 
to continue reporting future results that are as impressive as 
those reported in 2010.

Sincerely,

W. Stancil Starnes
Chief Executive Officer

P R O M I S E S   K E P T 
Treated Fairly

At the core of our business philosophy 
is the promise that we will treat 
all people fairly. By fulfilling this 
promise to everyone we encounter, 
in particular our insureds, we affirm 
that everyone has the right to be 
carefully heard and thoughtfully 
engaged in an open, transparent 
fashion. And we reinforce the values 
already present in our relationships 
with our insureds. To be treated fairly, 
of course, means different things to 
different people, but meeting the 
diverse expectations of everyone we 
encounter ensures that we remain one 
of the leading carriers in our industry.

Corporate Organization and History 

We were incorporated in Delaware as the successor to Medical Assurance, Inc. in connection 

with its merger with Professionals Group, Inc. (Professionals Group) in June 2001. 

Much of our growth has come through mergers and acquisitions; we are the successor to eighteen 

insurance organizations and have further grown our business with four significant renewal rights 
transactions. Key personnel have been retained in our acquisitions, allowing us to maintain market 
knowledge and preserve important institutional knowledge in underwriting, claims, risk management and 
marketing. Our ability to utilize this knowledge has allowed us to grow effectively through acquisitions. 

Recent Developments 

On November 30, 2010 we acquired 100% of the outstanding shares of American Physicians 

Service Group, Inc. (APS), whose primary operating entity is American Physicians Insurance Company 
(API), in a transaction valued at $237 million including cash paid of $233 million and deferred 
compensation commitments of $4 million. APS provides medical professional liability insurance 
primarily in Texas. See Note 2 to the Consolidated Financial Statements included herein for additional 
information regarding the acquisition of APS. 

In November 2010 the Board of Directors of ProAssurance authorized $200 million to be used for 

the repurchase of our common stock or debt securities, which was in addition to previous authorizations 
of $100 million in September 2009, $100 million in August 2008 and $150 million in April 2007. As of 
February 15, 2011 approximately $194.0 million of the total amount authorized by the Board remains 
available for use. 

On April 1, 2009 we acquired 100% of Podiatry Insurance Company of America and subsidiaries 

(PICA), and its wholly-owned subsidiary, PACO Assurance Company, Inc. (PACO), through a cash 
sponsored demutualization valued at $134 million, including future premium credits to qualified insureds 
of $15 million. PICA and PACO together provide professional liability insurance primarily to podiatric 
physicians, chiropractors and other healthcare providers throughout the United States. See Note 2 to the 
Consolidated Financial Statements included herein for additional information regarding the acquisition of 
PICA. 

In December 2008 we repurchased $23.0 million of our outstanding trust preferred securities for 
approximately $18.4 million. We recognized a gain of approximately $4.6 million on the extinguishment 
of debt which is discussed in more detail in Note 10 to the Consolidated Financial Statements included 
herein. The repurchased securities had been issued in April and May, 2004 as a part of a larger transaction 
wherein we issued $45.0 million of trust preferred securities, having a 30-year maturity and callable at par 
beginning in May 2009. The proceeds from the sale of the trust preferred securities were used for general 
corporate purposes, including contributions to the capital of our insurance subsidiaries to support growth 
in our insurance operations.  

In July 2008 we converted all our outstanding Convertible Debentures (aggregate principal of 

$107.6 million), issued in 2003, into approximately 2,572,000 shares of ProAssurance common stock. No 
gain or loss was recorded related to the conversion, which is discussed in more detail in Notes 10 and 11 
to the Consolidated Financial Statements, included herein. 

In December 2007 we redeemed, at face value, for cash, outstanding subordinated debentures of 
$15.5 million that became our obligation in 2005 when we acquired NCRIC Corporation (NCRIC), now 
ProAssurance Professional Liability Group.  

Effective August 1, 2006 we acquired 100% of the outstanding shares of Physicians Insurance 

Company of Wisconsin, Inc., now ProAssurance Wisconsin Insurance Company (PRA Wisconsin), in an 
all stock merger valued at $104 million. PRA Wisconsin provides professional liability insurance 
primarily to healthcare professionals and facilities in Midwestern and Western states.

Effective January 1, 2006 we sold the operating subsidiaries that comprised our personal lines 

operations, MEEMIC Insurance Company and MEEMIC Insurance Services (collectively, the MEEMIC 

7 

 
 
 
 
companies), for $400 million before taxes and transaction expenses. We recognized a gain on the sale in 
the first quarter of 2006 of $109.4 million after consideration of sales expenses and estimated taxes. We 
used the sale proceeds to support the capital requirements of our professional liability insurance 
subsidiaries and other general corporate purposes.  

Products, Services and Marketing  

Our insurance subsidiaries are primarily focused on providing professional liability insurance to 
the healthcare and legal marketplaces. We target the full spectrum of the healthcare professional liability 
market, with physicians as our core customer group. For our legal professional liability product, we target 
smaller law practices. While most of our business is written in the standard market, we also offer 
professional liability insurance on an excess and surplus lines basis. We are licensed to do business in 
every state. 

We utilize independent agents as well as an internal sales force to write our business. For the year 

ended December 31, 2010, we estimate that approximately 64% of our gross premiums written were 
produced through independent insurance agencies. We do not anticipate that inclusion of APS will have a 
meaningful impact on our sales distribution. These local agencies usually have producers who specialize 
in professional liability insurance and should be able to convey the factors that differentiate our 
professional liability insurance products. No single agent or agency accounts for more than 10% of our 
total direct premiums written. 

Our marketing approach is closely tied to our promise of “Treated Fairly” which is our public 

pledge that all of our actions will deliver fair treatment, informed by the core values that guide our 
organization: integrity, respect, doctor involvement in our healthcare insurance activities, collaboration, 
communication, and enthusiasm. We emphasize that we offer: 

financial strength, 

 
  excellent claims and underwriting services, 
  opportunities to participate in accredited risk management education seminars, 
 
 

risk management consultation, loss prevention seminars and other educational programs, 
regular  newsletters  discussing  matters  of  interest  to  healthcare  providers,  including  updates  on 
legislative developments, 
support of legislation that will have a positive effect on healthcare liability issues, and 
involvement in and support for local medical societies and related organizations. 

 
 

These communications and services demonstrate our understanding of the professional liability 

insurance needs of the healthcare industry, promote a commonality of interest among us and our insureds, 
and provide opportunities for targeted interactions with potential insureds. 

Underwriting 

Our underwriting process is driven by individual risk selection. Our underwriting decisions are 
focused on achieving pricing adequacy. We assess the quality and pricing of the risk, emphasizing loss 
history, areas of practice and location in making our underwriting decision. In performing their 
assessment, our underwriters may also consult with internal actuaries regarding loss trends and pricing 
and utilize loss-rating models to assess the projected underwriting results of certain insured risks. 

Our underwriting concentrates on knowledge of local market conditions and legal environments 
through market-focused underwriting offices located in Alabama, Georgia, Indiana, Michigan, Missouri, 
Tennessee, Texas, Wisconsin, and the District of Columbia. Our underwriters work closely with our 
claims departments, consulting with staff about claims histories and patterns of practice in a particular 
locale as well as monitoring claims activity.

For our medical professional liability business underwriters are assisted by our medical advisory 

committees that operate in our key markets. These committees are comprised of physicians, other 

8 

 
 
 
healthcare providers and representatives of hospitals and healthcare entities and help us maintain close 
ties to the medical communities in these markets, provide information on the practice of medicine in each 
market and provide guidance on critical underwriting issues. 

Claims Management 

We have local claims offices located in Alabama, Delaware, Florida, Georgia, Illinois, Indiana, 

Kentucky, Michigan, Missouri, Ohio, Tennessee, Texas, Virginia, Wisconsin, and the District of 
Columbia so that we can provide specialized and timely attention to claims. We offer our insureds a 
strong defense of claims that we believe are non-meritorious or those we believe cannot be settled by 
reasonable, good faith negotiations. Many of these claims are resolved by jury verdict, and we engage 
experienced, independent trial attorneys in each venue to handle the litigation in defense of our 
policyholders. 

Our claims department promptly and thoroughly investigates the circumstances surrounding a 
reported claim against an insured. As this investigation progresses, our claims department develops an 
estimate of the case reserves for each claim. Thereafter, we monitor development of new information 
about the claim and adjust the case reserve as loss cost estimates are revised. 

Through our investigation, and in consultation with the insured and appropriate experts, we 
evaluate the merit of the claim and either seek reasonable good faith settlement or aggressively defend the 
claim. Our claims department carefully manages the case, including selecting independent defense 
attorneys who specialize in professional liability defense and obtaining medical, legal and/or other expert 
professionals to assist in the analysis and defense of the claim. As part of the evaluation and preparation 
process for medical professional liability claims, we meet regularly with medical advisory committees in 
our key markets to examine claims, attempt to identify potentially troubling practice patterns and make 
recommendations to our staff. 

We believe that our claims philosophy contributes to lower overall loss costs and results in 

customer loyalty. Our success in claims management is greatly enhanced by our local presence in many 
of the markets we serve. Our claims offices in those markets are staffed with experienced claims 
professionals who possess specialized knowledge of the local medical and legal environments. We have 
access to attorneys with significant experience in the defense of professional liability claims in those local 
jurisdictions and who are able to defend claims in an aggressive, cost-efficient manner. 

Investments  

The majority of our assets are held in our individual operating insurance companies and we apply 

a consistent management strategy to the entire portfolio. 

Our overall investment strategy is to focus on maximizing current income from our investment 

portfolio while maintaining safety, liquidity, duration targets and portfolio diversification. The portfolio is 
generally managed by professional third party asset managers whose results we monitor and evaluate. The 
asset managers typically have the authority to make investment decisions within the asset class they are 
responsible for managing, subject to our investment policy and oversight, including a requirement that 
securities in a loss position cannot be sold without specific authorization from us. See Note 4 to the 
Consolidated Financial Statements for more information on our investments. 

Rating Agencies  

Our claims-paying ability and financial strength are regularly evaluated and rated by three major 
rating agencies, A. M. Best, Fitch and Moody’s. In developing their claims-paying ratings, these agencies 
make an independent evaluation of an insurer’s ability to meet its obligations to policyholders. While 
these ratings may be of interest to investors, these are not ratings of our securities nor a recommendation 
to buy, hold or sell any of our securities.

Competition 

We compete in a fragmented market with many insurance companies and alternative insurance 
mechanisms such as risk retention groups or self-insuring entities. Competition depends on a number of 
factors including pricing, size, name recognition, service quality, market commitment, market conditions, 
breadth and flexibility of coverage, method of sale, financial stability, ratings assigned by rating agencies 
and regulatory conditions. 

Our financial stability, local market presence and knowledge, leading position in a number of 
markets, service quality, size, and geographic scope provide competitive advantages.  We are widely 
recognized in our markets for our heritage as a policyholder-founded company with a long-term focus on 
the professional liability insurance industry as well as our demonstrated commitment to the defense of 
non-meritorious claims and the prompt, reasonable settlement of those claims that involve a breach of the 
applicable standard of professional care by our insured, causing damages covered by our insurance policy. 

Our operating model of maintaining regional claims and underwriting offices staffed with 
experienced underwriting and claims professionals also provides competitive advantages. We utilize our 
local market knowledge to rigorously underwrite each application for coverage to ensure that we 
understand the risks we accept, and develop an adequate price for that risk. Our local market knowledge 
also allows us to effectively evaluate claims because we have a detailed understanding of local medical 
and legal climates. We maintain active relationships with our customers and emphasize high 
responsiveness to customer needs.  

Additionally, we differentiate ProAssurance from our competitors through our “Treated Fairly” 

brand. “Treated Fairly” is our public pledge that all of our actions will deliver fair treatment, informed by 
the core values that guide our organization: integrity, respect, doctor involvement in our healthcare 
insurance activities, collaboration, communication, and enthusiasm. Our competitors include smaller 
insurance entities that concentrate on a single state and also have an extensive knowledge of the local 
markets. We also compete with several large national insurers whose financial strength and resources may 
be greater than ours. We consider our largest nationwide competitors to be The Medical Protective 
Company (Berkshire Hathaway) and The Doctors Company.

Improvements in loss cost trends have allowed us to reduce rates in many markets and offer 

targeted new business and renewal retention programs in selected markets. These steps improve 
policyholder retention but decrease our average premiums. While we reflect loss cost trends in our 
pricing, we do not aggressively compete on price alone, and we have not compromised our commitment 
to strict underwriting. 

We have lost some insureds due to aggressive, price-based competition which we face in virtually 

all of our markets. This competition comes mostly from established insurers that are willing to write 
coverage at rates that we believe do not meet our long-term profitability goals. We believe many 
competitors are also employing less-stringent underwriting standards than they have in the past and they 
appear to be offering more liberal coverage options. 

We have also seen a trend towards hospitals purchasing physician practices in recent years. We 

have also lost insureds as some physicians and hospitals have entered into alternative risk transfer 
mechanisms such as self insurance and risk sharing pools. Historically, these alternatives have been less 
attractive when prices soften in the traditional insurance markets although many of these alternative 
arrangements have remained in place through previous soft markets. 

If competitors continue to be less disciplined in their pricing, or become more permissive in their 

coverage terms, we could lose business because our ongoing commitment to adequate rates and strong 
underwriting standards affects our willingness to write new business and to renew existing business in the 
face of this price-based competition. 

Insurance Regulatory Matters 

We are subject to regulation under the insurance and insurance holding company statutes of 
various jurisdictions including the domiciliary states of our insurance subsidiaries and other states in 
which our insurance subsidiaries do business. Our insurance subsidiaries are domiciled in Alabama, 
Illinois, Michigan, Texas, Wisconsin, and the District of Columbia. 

Insurance companies are also affected by state and federal legislative and regulatory measures 

and judicial decisions. These could include new or updated definitions of risk exposure and limitations on 
business practices. In addition, individual state insurance departments may prevent premium rates for 
some classes of insureds from adequately reflecting the level of risk assumed by the insurer for those 
classes. 

Our operating subsidiaries are required to file detailed annual reports with the state insurance 

regulators in each of the states in which they do business. The laws of the various states establish agencies 
with broad authority to regulate, among other things, licenses to transact business, premium rates for 
certain types of coverage, trade practices, agent licensing, policy forms, underwriting and claims 
practices, reserve adequacy, transactions with affiliates, and insurer solvency. Many states also regulate 
investment activities on the basis of quality, distribution and other quantitative criteria. States have also 
enacted legislation regulating insurance holding company systems, including acquisitions, the payment of 
dividends, the terms of affiliate transactions, and other related matters. 

Applicable state insurance laws, rather than federal bankruptcy laws, apply to the liquidation or 

reorganization of insurance companies. 

11 

 
 
 
 
 
Insurance Regulation Concerning Change or Acquisition of Control 

The insurance regulatory codes in our operating subsidiaries’ respective domiciliary states each 

contain provisions (subject to certain variations) to the effect that the acquisition of “control” of a 
domestic insurer or of any person that directly or indirectly controls a domestic insurer cannot be 
consummated without the prior approval of the domiciliary insurance regulator. In general, a presumption 
of “control” arises from the direct or indirect ownership, control or possession with the power to vote or 
possession of proxies with respect to 10% (5% in Alabama) or more of the voting securities of a domestic 
insurer or of a person that controls a domestic insurer. Because of these regulatory requirements, any 
party seeking to acquire control of ProAssurance or any other domestic insurance company, whether 
directly or indirectly, would usually be required to file an application for approval of the proposed change 
of control with the relevant insurance regulatory authority. 

In addition, certain state insurance laws contain provisions that require pre-acquisition 

notification to state agencies of a change in control of a non-domestic insurance company admitted in that 
state. While such pre-acquisition notification statutes do not authorize the state agency to disapprove the 
change of control, such statutes do authorize certain remedies, including the issuance of a cease and desist 
order with respect to the non-domestic admitted insurers doing business in the state if certain conditions 
exist, such as undue market concentration. 

Statutory Accounting and Reporting 

Insurance companies are required to file detailed quarterly and annual reports with the state 

insurance regulators in each of the states in which they do business, and their business and accounts are 
subject to examination by such regulators at any time. The financial information in these reports is 
prepared in accordance with Statutory Accounting Principles (SAP). Insurance regulators periodically 
examine each insurer’s financial condition, adherence to SAP, and compliance with insurance department 
rules and regulations. 

In late 2010, the National Association of Insurance Commissioners (the NAIC) adopted the 

Model Insurance and Holding Company System Regulatory Act and Regulation (“Model Law”). The 
Model Law, as compared to currently existing NAIC guidance, increases regulatory oversight of and 
reporting by insurance holding companies, including reporting related to non-insurance entities, and 
requires reporting of risks affecting the holding company group. The Model Law will be binding only if 
adopted by state legislatures and/or state insurance regulatory authorities and actual regulations adopted 
by any state may differ from the Model Law. 

Regulation of Dividends and Other Payments from Our Operating Subsidiaries 

Our operating subsidiaries are subject to various state statutory and regulatory restrictions which 
limit the amount of dividends or distributions an insurance company may pay to its shareholders without 
prior regulatory approval. Generally, dividends may be paid only out of earned surplus. In every case, 
surplus subsequent to the payment of any dividends must be reasonable in relation to an insurance 
company’s outstanding liabilities and must be adequate to meet its financial needs. 

State insurance holding company regulations generally require domestic insurers to obtain prior 

approval of extraordinary dividends. Insurance holding company regulations that govern our principal 
operating subsidiaries except as described below, deem a dividend as extraordinary if the combined 
dividends and distributions to the parent holding company in any 12 month period are more than the 
greater of either the insurer’s net income for the prior fiscal year or 10% of its surplus at the end of the 
prior fiscal year. 

Our ProAssurance National Capital Insurance Company subsidiary is governed by District of 

Columbia insurance regulations, under which a dividend is deemed to be extraordinary if the combined 
dividends and distributions made in any 12 month period exceeds the lesser of net income less capital 
gains or 10% of surplus at the prior calendar year end. 

12 

 
 
 
Our ProAssurance Wisconsin Insurance Company subsidiary is governed by Wisconsin insurance 

regulations, under which a dividend is deemed to be extraordinary if the amount exceeds the lesser of 
10% of a company’s capital and surplus as of December 31 of the preceding year or the greater of 
statutory net income for the preceding calendar year minus realized capital gains for that calendar year, or 
the aggregate of statutory net income for the three previous calendar years minus realized capital gains for 
those calendar years, minus dividends paid or credited and distributions made within the first two of the 
preceding three calendar years. 

Additionally, we have made a written representation to the Texas Department of Insurance that 

we would not pay any dividend from our API subsidiary before June 1, 2011. If insurance regulators 
determine that payment of a dividend or any other payments to an affiliate (such as payments under a tax-
sharing agreement or payments for employee or other services) would, because of the financial condition 
of the paying insurance company or otherwise, be a detriment to such insurance company’s policyholders, 
the regulators may prohibit such payments that would otherwise be permitted.  

Risk-Based Capital 

In order to enhance the regulation of insurer solvency, the National Association of Insurance 

Commissioners specifies risk-based capital requirements for property and casualty insurance companies. 
At December 31, 2010, all of ProAssurance’s insurance subsidiaries exceeded their minimum risk based 
capital levels. 

Investment Regulation 

Our operating subsidiaries are subject to state laws and regulations that require diversification of 
investment portfolios and that limit the amount of investments in certain investment categories. Failure to 
comply with these laws and regulations may cause non-conforming investments to be treated as non-
admitted assets for purposes of measuring statutory surplus and, in some instances, would require 
divestiture of investments. We monitor the practices used by our operating subsidiaries for compliance 
with applicable state investment regulations and take corrective measures when deficiencies are 
identified. 

Guaranty Funds 

Admitted insurance companies are required to be members of guaranty associations which 
administer state guaranty funds. These associations levy assessments to fund the payment of claims 
against insurance companies that fail (up to prescribed limits) on all member insurers in a particular state 
on the basis of the proportionate share of the premiums written by member insurers in the covered lines of 
business in that state. Maximum assessments permitted by law in any one year generally vary between 
1% and 2% of annual premiums written by a member in that state. Some states permit member insurers to 
recover assessments paid through surcharges on policyholders or through full or partial premium tax 
offsets, while other states permit recovery of assessments through the rate filing process.  

Shared Markets 

State insurance regulations may force us to participate in mandatory property and casualty shared 

market mechanisms or pooling arrangements that provide certain insurance coverage to individuals or 
other entities that are otherwise unable to purchase such coverage in the commercial insurance 
marketplace. Our operating subsidiaries’ participation in such shared markets or pooling mechanisms is 
not material to our business at this time.

Changes in Legislation and Regulation 

In recent years, the insurance industry has been subject to increased scrutiny by regulators and 

legislators. The NAIC and a number of state legislatures have considered or adopted legislative proposals 
that alter and, in many cases, increase the authority of state agencies to regulate insurance companies and 
insurance holding company systems. 

Tort reforms generally restrict the ability of a plaintiff to recover damages by, among other 
limitations, eliminating certain claims that may be heard in a court, limiting the amount or types of 
damages, changing statutes of limitation or the period of time to make a claim, and limiting venue or 
court selection. A number of states in which we do business, notably Florida, Georgia, Illinois, Missouri, 
Ohio, Texas, and West Virginia, enacted tort reform legislation in the previous decade as a response to a 
rapid deterioration in loss trends. These reforms are generally thought to have contributed to the 
improvement in the overall loss trends in those states, although loss trends have also been favorable in 
states that did not pass any type of tort reform. In states where these reforms are perceived to have 
improved the medical professional liability climate, we have experienced an increase in competition. 

The Illinois and Georgia tort reform statutes were overturned in 2010 and challenges to tort 

reform are underway in most states where tort reforms have been enacted. The Illinois statute was 
overturned in early 2010. Other state reforms may also be overturned, although we cannot predict with 
any certainty how appellate courts will rule. We continue to monitor developments on a state-by-state 
basis and make business decisions accordingly.  

Tort reform proposals are considered from time-to-time at the Federal level. As in the states, 

passage of a Federal tort reform package would likely be subject to judicial challenge and we cannot be 
certain that it would be upheld by the courts. 

The Patient Protection and Affordable Care Act of 2010, otherwise known as the Healthcare 

Reform Act, was passed and signed into law in March 2010. Although a few provisions of the Act have 
already become effective, the most comprehensive provisions will become effective beginning in 2013. It 
does not appear that the provisions enacted will have a significant direct effect on our business, but 
specific regulations to implement the law are still being written. These regulations could have 
unanticipated or indirect effects on our business or alter the risk and cost environments in which we and 
our insureds operate. Additionally, the Healthcare Reform Act is a complex document that contains 
numerous administrative provisions that deal with non-healthcare matters. Regulations to implement these 
non-healthcare provisions are being developed and may impose additional administrative burdens that 
increase our operating costs. Furthermore, there are ongoing legal challenges and potential legislative 
changes that may be introduced during 2011 that may repeal or substantially alter the Healthcare Reform 
Act. We are unable to predict with any certainty the effect that the Healthcare Reform Act or future 
related legislation will have on our insureds or our business.  

The Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act) was passed 

in July 2010. Although many provisions of the Act do not appear to directly affect our business, the Act 
establishes new regulatory oversight of financial institutions. As detailed regulations are developed to 
implement the provisions of the Act, there may be changes in the regulatory environment that affect the 
way we conduct our operations or the cost of compliance, or both. 

Other federal initiatives could be proposed, including additional patient protection legislation that 

could ultimately affect our business. We are unable to predict the likelihood of any particular type of 
legislation becoming effective or the ramifications to our business. 

Employees  

At December 31, 2010, we had 739 employees, none of whom are represented by a labor union. 

We consider our employee relations to be good.

ITEM 1A.  RISK FACTORS. 

There are a number of factors, many beyond our control, which may cause results to differ 

significantly from our expectations. Some of these factors are described below. Any factor described in 
this report could by itself, or together with one or more other factors, have a negative effect on our 
business, results of operations and/or financial condition. There may be factors not described in this report 
that could also cause results to differ from our expectations. 

Insurance market conditions may alter the effectiveness of our current business strategy and impact our 
revenues. 

The property and casualty insurance business is highly competitive. We compete with large 
national property and casualty insurance companies, locally-based specialty companies, self-insured 
entities and alternative risk transfer mechanisms (such as captive insurers and risk retention groups) 
whose activities are directed to limited markets in which they have extensive knowledge. Competitors 
include companies that have substantially greater financial resources than we do, hospitals purchasing 
physician practices, as well as mutual companies and similar companies not owned by shareholders 
whose return on equity objectives may be lower than ours. 

Competition in the property and casualty insurance business is based on many factors, including 

premiums charged and other terms and conditions of coverage, services provided, financial ratings 
assigned by independent rating agencies, claims services, reputation, geographic scope, local presence, 
agent and client relationships, financial strength and the experience of the insurance company in the line 
of insurance to be written. Increased competition could adversely affect our ability to attract and retain 
business at current premium levels, impact our market share and reduce the profits that would otherwise 
arise from operations. 

Our operating results and financial condition may be affected if actual insured losses differ from our loss 
reserves. 

We establish reserves as balance sheet liabilities representing our estimates of amounts needed to 

pay reported and unreported losses and the related loss adjustment expense. Our largest liability is our 
reserve for loss and loss adjustment expenses. Due to the size of our reserve for loss and loss adjustment 
expenses, even a small percentage adjustment to our reserve can have a material effect on our results of 
operations for the period in which the change is made.  

The process of estimating loss reserves is complex. Significant periods of time often elapse 

between the occurrence of an insured loss, the reporting of the loss by the insured and payment of that 
loss. Ultimate loss costs, even for claims with similar characteristics, can vary significantly depending 
upon many factors, including but not limited to, the nature of the claim and the personal situation of the 
claimant or the claimant's family, the outcome of jury trials, the legislative and judicial climate where the 
insured event occurred, general economic conditions and, for medical professional liability, the trend of 
health care costs. Consequently, the loss cost estimation process requires actuarial skill and the 
application of judgment, and such estimates require periodic revision. As part of the reserving process, we 
review the known facts surrounding reported claims as well as historical claims data and consider the 
impact of various factors such as: 

– 
for reported claims, the nature of the claim and the jurisdiction in which the claim occurred; 
– 
trends in paid and incurred loss development; 
– 
trends in claim frequency and severity; 
–  emerging economic and social trends; 
– 
– 
–  changes in the regulatory legal and political environment. 

trend of health care costs for medical professional liability; 
inflation; and 

15 

 
 
 
This process assumes that past experience, adjusted for the effects of current developments and 

anticipated trends, is an appropriate, but not necessarily accurate, basis for predicting future events. There 
is no precise method for evaluating the impact of any specific factor on the adequacy of reserves, and 
actual results are likely to differ from original estimates. Our loss reserves also may be affected by court 
decisions that expand liability on our policies after they have been issued and priced. In addition, a 
significant jury award, or series of awards, against one or more of our insureds could require us to pay 
large sums of money in excess of our reserved amounts. Due to uncertainties inherent in the jury system, 
each case that is litigated to a jury verdict increases our risk of incurring a loss that has a material adverse 
affect on reserves. To the extent loss reserves prove to be inadequate to meet future claim payments, we 
would incur a charge to earnings in the period the reserves are increased. 

We purchase reinsurance to mitigate the effect of large losses. Our receivable from reinsurers on 

unpaid losses and loss adjustment expenses represents our estimate of the amount of our reserve for losses 
that will be recoverable under our reinsurance programs. We base our estimate of funds recoverable upon 
our expectation of ultimate losses and the portion of those losses that we estimate to be allocable to 
reinsurers based upon the terms of our reinsurance agreements. Given the uncertainty of the ultimate 
amounts of our losses, our estimates of losses and related amounts recoverable may vary significantly 
from the eventual outcome. Also, we estimate premiums ceded under reinsurance agreements wherein the 
premium due to the reinsurer, subject to certain maximums and minimums, is based in part on losses 
reimbursed or to be reimbursed under the agreement. Due to the size of our reinsurance balances, an 
adjustment to these estimates could have a material effect on our results of operations for the period in 
which the adjustment is made. Any adjustments are reflected in then-current operations. 

If market conditions cause reinsurance to be more costly or unavailable, we may be required to bear 
increased risks or reduce the level of our underwriting commitments. 

As part of our overall risk and capacity management strategy, we purchase reinsurance for 
significant amounts of risk underwritten by our insurance company subsidiaries. Market conditions 
beyond our control determine the availability and cost of the reinsurance. We may be unable to maintain 
current reinsurance coverage or to obtain other reinsurance coverage in adequate amounts and at 
favorable rates. If we are unable to renew our expiring coverage or to obtain new reinsurance coverage, 
either our net exposure to risk would increase or, if we are unwilling to bear an increase in net risk 
exposures, we would have to reduce the amount of our underwritten risk. 

We cannot guarantee that our reinsurers will pay in a timely fashion or if at all, and, as a result, we could 
experience losses. 

We transfer part of our risks to reinsurance companies in exchange for part of the premium we 

receive in connection with the risk. Although our reinsurance agreements make the reinsurer liable to us 
to the extent the risk is transferred, the liability to our policyholders remains our responsibility. If 
reinsurers fail to pay us or fail to pay on a timely basis, our financial results and/or cash flows would be 
adversely affected. At December 31, 2010 our Receivable from Reinsurers on Unpaid Losses is $277.4 
million and our Receivable from Reinsurers on Paid Losses is $4.6 million. 

Our claims handling practices could result in a bad faith claim against us. 

We have been, from time-to-time, sued for allegedly acting in bad faith during our handling of 

a claim. The damages in actions for bad faith may include amounts owed by the insured in excess of 
the policy limits as well as consequential and punitive damages. Awards above policy limits are 
possible whenever a case is taken to trial. These actions have the potential to have a material adverse 
effect on our financial condition and results of operations. 

16 

 
 
 
 
 
Changes in healthcare policy could have a material effect on our operations.  

The Patient Protection and Affordable Care Act of 2010, otherwise known as the Healthcare 

Reform Act, was passed and signed into law in March 2010. While the primary provisions of the 
Healthcare Reform Act do not appear to directly affect our business, specific regulations to implement the 
law are still being written. The effect of these regulations could have unanticipated or indirect effects on 
our business or alter the risk and cost environments in which we and our insureds operate. Additionally, 
the Healthcare Reform Act is a complex document that contains numerous administrative provisions that 
deal with non-healthcare matters. Regulations to implement these provisions are being developed and 
may impose additional administrative burdens that will increase our operating costs. Furthermore, there 
are ongoing legal challenges and potential legislative changes that may be introduced during 2011 that 
may repeal or substantially alter the Healthcare Reform Act. We are unable to predict with any certainty 
the effect that the Healthcare Reform Act or future related legislation will have on our insureds or our 
business. 

Changes due to recent financial reform legislation could have a material effect on our operations. 

The Dodd-Frank Act was passed and signed into law in July 2010. The provisions of the bill do 

not appear to directly affect our operations; however, the bill establishes new regulatory oversight of 
financial institutions. As detailed regulations are developed to implement the provisions of the bill, there 
may be changes in the regulatory environment that affect the way we conduct our operations or the cost of 
regulatory compliance, or both. We are unable to predict with any certainty the effect that the Dodd-Frank 
Act or future related legislation will have on our insureds or our business. 

The passage of tort reform or other legislation, and the subsequent review of such laws by the courts 
could have a material impact on our operations. 

Tort reforms generally restrict the ability of a plaintiff to recover damages by, among other 
limitations, eliminating certain claims that may be heard in a court, limiting the amount or types of 
damages, changing statutes of limitation or the period of time to make a claim, and limiting venue or 
court selection. A number of states in which we do business, notably Florida, Georgia, Illinois, Missouri, 
Ohio, Texas, and West Virginia, enacted tort reform legislation in the previous decade as a response to a 
rapid deterioration in loss trends. The statutes in Georgia and Illinois were overturned in 2010. We cannot 
predict with any certainty how other state appellate courts will rule on these laws. While the effects of tort 
reform have been generally beneficial to our business in states where these laws have been enacted, there 
can be no assurance that such reforms will be ultimately upheld by the courts. Further, if tort reforms are 
effective, the business of providing professional liability insurance may become more attractive, thereby 
causing an increase in competition. In addition, the enactment of tort reforms could be accompanied by 
legislation or regulatory actions that may be detrimental to our business because of expected benefits 
which may or may not be realized. These expectations could result in regulatory or legislative action 
limiting the ability of professional liability insurers to maintain rates at adequate levels. Coverage 
mandates or other expanded insurance requirements could also be imposed. States may also consider state 
sponsored malpractice insurance entities that could remove some physicians from the private insurance 
market. 

We continue to monitor developments on a state-by-state basis, and make business decisions 

accordingly. 

17 

 
 
 
 
 
A significant amount of our business is concentrated in certain states so that our performance is 
dependent on the business, economic, regulatory and legislative conditions in those states. 

Our top five states, Alabama, Ohio, Florida, Indiana and Michigan, represented 46% of our 

gross premiums written for the year ended December 31, 2010. Moreover, on a combined basis, 
Alabama and Ohio accounted for 26%, 30%, and 35%, of our gross premiums written for the years 
ended December 31, 2010, 2009 and 2008, respectively. Texas would have represented approximately 
11% of our total gross premiums written in 2010 had we included a full year of APS premium. 
Because of these concentrations, unfavorable business, economic or regulatory conditions in any of 
these states could have a disproportionately greater effect on us than they would if we were less 
geographically concentrated. 

We may be unable to identify future strategic acquisitions or expected benefits from completed and 
proposed acquisitions may not be achieved or may be delayed longer than expected. 

Our corporate strategy anticipates growth through the acquisition of other companies or books 
of business. However, such expansion is opportunistic and there is no guarantee that we will be able to 
identify strategic acquisition targets in the future. Additionally, if we are able to identify a strategic 
target for acquisition, state insurance regulation concerning change or acquisition of control could 
delay or prevent us from growing through acquisitions. Many states' insurance regulatory codes 
provide that the acquisition of "control" of a domestic insurer or of any person that directly or 
indirectly controls a domestic insurer cannot be consummated without the prior approval of the 
domiciliary insurance regulator. There is no assurance that we will receive such approval from the 
respective insurance regulator.  

When we are able to complete an acquisition, such as our recent acquisitions of PICA and 
APS, there is no guarantee that the expected benefits will be achieved as planned. The process of 
integrating an acquired company or business can be complex and costly, and may create unforeseen 
operating difficulties and expenditures. Potential problems that may arise include, among other 
reasons, business disruption, loss of customers and employees, the ineffective integration of 
underwriting, claims handling and actuarial practices, the increase in the inherent uncertainty of 
reserve estimates for a period of time until stable trends reestablish themselves within the combined 
organization, diversion of management time and resources to acquisition integration challenges, the 
cultural challenges associated with integrating employees, increased operating costs or inability to 
achieve cost savings, and the assumption of greater than expected liabilities. There is no guarantee that 
any businesses acquired in the future will be successfully integrated, and the ineffective integration of 
our businesses and processes may result in substantial costs or delays and adversely affect our ability 
to compete. 

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 financial strength (including claims-paying 
ability) of insurers based upon criteria established by the agencies. Periodically the rating agencies 
evaluate us to confirm that we continue to meet the criteria of previously assigned ratings. The financial 
strength ratings assigned by rating agencies to insurance companies represent independent opinions of 
financial strength and ability to meet policyholder obligations and are not directed toward the protection 
of investors. Ratings by rating agencies are not ratings of securities or recommendations to buy, hold or 
sell any security. 

Our principal operating subsidiaries hold favorable financial strength ratings with A.M. Best, 

Fitch and Moody’s. Financial strength ratings are used by agents and customers as an important means of 
assessing the financial strength and quality of insurers. If our financial position deteriorates or the rating 
agencies significantly change the rating criteria that are used to determine ratings, we may not maintain 

18 

 
 
 
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 rating process is dynamic and ratings can change. If you are seeking updated information 

about our ratings, please visit the rating agency websites listed in the table. 

Our business could be adversely affected by the loss of independent agents. 

We depend in part on the services of independent agents in the marketing of our insurance 

products. We face competition from other insurance companies for the services and allegiance of 
independent agents. These agents may choose to direct business to competing insurance companies. 

Our business could be adversely affected by the loss of one or more key employees. 

We are heavily dependent upon our senior management and the loss of services of our senior 

executives could adversely affect our business. Our success has been, and will continue to be, dependent 
on our ability to retain the services of existing key employees and to attract and retain additional qualified 
personnel in the future. The loss of the services of key employees or senior managers, or the inability to 
identify, hire and retain other highly qualified personnel in the future, could adversely affect the quality 
and profitability of our business operations. 

Our board of directors regularly reviews succession planning relating to our Chief Executive 
Officer as well as other senior officers. Mr. Starnes, our Chief Executive Officer, has indicated to the 
board that he has no immediate plans for retirement. 

Provisions in our charter documents, Delaware law and state insurance law may impede attempts to 
replace or remove management or impede a takeover, which could adversely affect the value of our 
common stock. 

Our certificate of incorporation, bylaws and Delaware law contain provisions that may have the 

effect of inhibiting a non-negotiated merger or other business combination. We currently have no 
preferred stock outstanding, and no present intention to issue any shares of preferred stock. In addition, 
our Board of Directors has amended our Corporate Governance Principles to provide that the Board of 
Directors, subject to its fiduciary duties, will not issue any series of preferred stock for any defense or 
anti-takeover purpose, for the purpose of implementing any stockholders rights plan, or with features 
intended to make any acquisition more difficult or costly without obtaining stockholder approval. 
However, because the rights and preferences of any series of preferred stock may be set by the board of 

19 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
directors in its sole discretion, the rights and preferences of any such preferred stock may be superior to 
those of our common stock and thus may adversely affect the rights of the holders of common stock. 

The voting structure of common stock and other provisions of our certificate of incorporation are 
intended to encourage a person interested in acquiring us to negotiate with, and to obtain the approval of, 
the board of directors in connection with a transaction. However, certain of these provisions may 
discourage our future acquisition, including an acquisition in which stockholders might otherwise receive 
a premium for their shares. As a result, stockholders who might desire to participate in such a transaction 
may not have the opportunity to do so. 

In addition, state insurance laws provide that no person or entity may directly or indirectly 

acquire control of an insurance company unless that person or entity has received approval from the 
insurance regulator. An acquisition of control would be presumed if any person or entity acquires 10% 
(5% in Alabama) or more of our outstanding common stock, unless the applicable insurance regulator 
determines otherwise. These provisions apply even if the offer may be considered beneficial by 
stockholders. 

We are a holding company and are dependent on dividends and other payments from our operating 
subsidiaries, which are subject to dividend restrictions. 

We are a holding company whose principal source of funds is cash dividends and other permitted 

payments from operating subsidiaries. If our subsidiaries are unable to make payments to us, or are able 
to pay only limited amounts, we may be unable to make payments on our indebtedness. The payment of 
dividends by these operating subsidiaries is subject to restrictions set forth in the insurance laws and 
regulations of their respective states of domicile, as discussed in Item 1 Insurance Regulatory Matters. 

Regulatory requirements could have a material effect on our operations. 

Our insurance businesses are subject to extensive regulation by state insurance authorities in each 

state in which they operate. Regulation is intended for the benefit of policyholders rather than 
shareholders. In addition to the amount of dividends and other payments that can be made to a holding 
company by insurance subsidiaries, these regulatory authorities have broad administrative and 
supervisory power relating to: 

licensing requirements;  
trade practices;  

– 
– 
–  capital and surplus requirements;  
– 
– 

investment practices; and  
rates charged to insurance customers. 

These regulations may impede or impose burdensome conditions on rate changes or other actions 

that we may want to take to enhance our operating results. In addition, we may incur significant costs in 
the course of complying with regulatory requirements. Most states also regulate insurance holding 
companies like us in a variety of matters such as acquisitions, changes of control and the terms of 
affiliated transactions. 

Future legislative or regulatory changes may also adversely affect our business operations. 

The guaranty fund assessments that we are required to pay to state guaranty associations may increase 
and results of operations and financial condition could suffer as a result. 

Each state in which we operate has separate insurance guaranty fund laws requiring admitted 
property and casualty insurance companies doing business within their respective jurisdictions to be 
members of their guaranty associations. These associations are organized to pay covered claims (as 
defined and limited by the various guaranty association statutes) under insurance policies issued by 
insurance companies that have become insolvent. Most guaranty association laws enable the associations 

20 

 
 
 
to make assessments against member insurers to obtain funds to pay covered claims after a member 
insurer becomes insolvent. These associations levy assessments (up to prescribed limits) on all member 
insurers in a particular state on the basis of the proportionate share of the premiums written by member 
insurers in the covered lines of business in that state. Maximum assessments permitted by law in any one 
year generally vary between 1% and 2% of annual premiums written by a member in that state, although 
one notable exception occurred in Florida in 2006, when the state assessed all property casualty insurers a 
total of 4% of their non-property premiums to offset bankruptcies caused by hurricane claims. Some 
states permit member insurers to recover assessments paid through surcharges on policyholders or 
through full or partial premium tax offsets, while other states permit recovery of assessments through the 
rate filing process. 

In 2010 and 2009, guaranty fund refunds/recoupments exceeded current year assessments by $1.3 

million and $0.5 million, respectively, which reduced total acquisition expenses. Our policy is to accrue 
for the insurance insolvencies when notified of assessments. We are not able to reasonably estimate the 
liabilities of an insolvent insurer or develop a meaningful range of the insolvent insurer’s liabilities 
because the guaranty funds do not provide sufficient information for development of such ranges. 

Our investment results will fluctuate as interest rates change. 

Our investment portfolio is primarily comprised of interest-earning assets. Thus, prevailing 

economic conditions, particularly changes in market interest rates, may significantly affect our operating 
results. Significant movements in interest rates potentially expose us to lower yields or lower asset values. 
Changes in market interest rate levels generally affect our net income to the extent that reinvestment 
yields are different than the yields on maturing securities. Changes in interest rates also can affect the 
value of our interest-earning assets, which are principally comprised of fixed and adjustable-rate 
investment securities. Generally, the values of fixed-rate investment securities fluctuate inversely with 
changes in interest rates. Interest rate fluctuations could adversely affect our stockholders’ equity, income 
and/or cash flows.  

Our investments are subject to credit and prepayment risk.  

A significant portion of our assets ($4.0 billion or 82%) at December 31, 2010 are financial 
instruments whose value can be significantly affected by economic and market factors beyond our control 
including, among others, the unemployment rate, the strength of the domestic housing market, the price of 
oil, changes in interest rates and spreads, consumer confidence, investor confidence regarding the 
economic prospects of the entities in which we invest, corrective or remedial actions taken by the entities 
in which we invest, including mergers, spin-offs and bankruptcy filings, the actions of the U.S. 
government, and global perceptions regarding the stability of the U.S. economy. Adverse economic and 
market conditions could cause investment losses or other-than-temporary impairments of our securities, 
which could affect our financial condition, results of operations, or cash flows. 

Our portfolio holds asset-backed securities which consist of securitizations of underlying loans 
collateralized by homes, autos, credit card receivables, commercial properties, hotels, and multi-family 
housing. In addition to interest rate fluctuations, asset-backed security values are affected by the existence 
of U.S. Government or Government-Sponsored Enterprise guarantees, the value and cash flows of the 
underlying collateral, and the security’s seniority in the securitization’s capital structure. Approximately 
18% ($731.8 million fair value) of our investments are asset-backed securities, 97% of which are 
investment grade (94% AAA, 1% AA, 1% A, 1% BBB) as determined by Nationally Recognized 
Statistical Rating Organizations (NRSROs) (Moody’s, Standard & Poor’s and Fitch). Ratings published 
by the NRSROs are among the tools used to evaluate the credit worthiness of our securities. The ratings 
are subject to error by the agencies; therefore, we may be subject to additional credit exposure should the 
rating be misstated.

We hold investments in non-agency mortgage-backed securities with a fair value of 

approximately $23.8 million ($23.8 million recorded cost basis). We also hold agency mortgage-backed 
securities which are guaranteed by Ginnie Mae, Fannie Mae, or Freddie Mac, having a combined fair 
value of $524.8 million ($503.2 million recorded cost basis).  

We have direct exposure with a fair value of $12.5 million in asset-backed securitizations that we 

classify as subprime. We have no exposure to subprime loans through collateralized debt obligations 
(CDOs). 

Our investment portfolio contains $99.4 million fair value of Commercial Mortgage-Backed 
Securities (CMBS) which are affected by the general health of the economy. As occupancy rates for 
commercial buildings and hotels have declined in recent years, fair values for many CMBS securities 
have declined. While we primarily hold high quality CMBS in our portfolio (average rating is AAA), 
there is no guarantee that fair values will be maintained in the future if delinquencies continue or increase 
or the economy does not maintain stability. 

The economic downturn in preceding years lessened tax receipts and other revenues in many 

states and their municipalities and the frequency of credit downgrades of these entities has increased. At 
December 31, 2010 the fair value of our state/municipal portfolio is $1.24 billion (recorded cost basis of 
$1.20 billion). While our state/municipal portfolio has a high credit rating (AA on average) which 
indicates a strong ability to pay, there is no assurance that there will not be a credit related event in our 
state and municipal bond portfolios which would cause fair values to decline.  

Our asset-backed securities are also subject to prepayment risk. A prepayment is the unscheduled 
return of principal. When rates decline, the propensity for refinancing may increase and the period of time 
we hold our asset-backed securities may shorten due to prepayments. Prepayments may cause us to 
reinvest cash flows at lower yields than currently recognized. Conversely, as rates increase, and 
motivations for refinancing lessen, the period of time we hold our asset-backed securities may lengthen, 
causing us to not reinvest cash flows at then higher available yields. 

In a period of market illiquidity and instability, the fair values of our investments are more difficult to 
assess and our assessments may prove to be greater or less than amounts received in actual transactions. 

In accordance with applicable GAAP, we value 96% of our investments at fair value and the 

remaining 4% at cost, equity, or cash surrender value. See Notes 1, 3 and 4 to the Consolidated Financial 
Statements for additional information. Approximately 5% of investments are traded in active markets and 
we use quoted market prices to value those investments. We estimate fair values for the remaining 91% of 
our investments, based on broker dealer quotes and various other valuation methodologies, which may 
require us to choose among various input assumptions and which requires us to utilize judgment. When 
markets exhibit much volatility, there is more risk that we may utilize a quoted market price, broker 
dealer quote, valuation technique or input assumption that results in a fair value estimate that is either 
over or understated as compared to actual amounts received upon disposition or maturity of the security.

Resolution of uncertain income tax matters and changes in tax laws could adversely affect our results of 
operations or cash flow. 

Our provision for income taxes, our recorded tax liabilities and net deferred tax assets, including 
any valuation allowances, are recorded based on estimates. These estimates require us to make significant 
judgments regarding a number of factors, including, among others, the applicability of various federal and 
state laws, the interpretations given to those tax laws by taxing authorities, courts and ProAssurance, the 
timing of future income and deductions, and our expected levels and source of future taxable income. We 
believe our tax positions are supportable under tax laws and that our estimates are prepared in accordance 
with GAAP. Nevertheless, we are periodically under routine examination by various federal, state and 
local authorities regarding income tax matters and our tax positions could be successfully challenged; the 
costs of defending our tax position could be considerable. Additionally, from time to time there are 
changes to tax laws and interpretations of tax laws which could change our estimates of the amount of tax 
benefits or deductions expected to be available to us in future periods. In either case, changes to our prior 
estimates would be reflected in the period changed and could have a material effect on our effective tax 
rate, financial position, results of operations and cash flow.  

ProAssurance is subject to U. S. federal and various state income taxes, and generally remains 

open to income tax examinations by tax authorities for years beginning with 2006. From time to time, we 
have tax positions being reviewed by the IRS or state taxing authorities. Our expectation regarding the 
resolution of those reviews is reflected in our then-current period financial statements. We are currently 
under audit by the IRS for years 2006 to 2008. We are unaware of any audit findings that would 
significantly change our tax liabilities. As of December 31, 2010 our current tax liability is approximately 
$26.1 million, and we have a net deferred tax asset of approximately $56.9 million. 

New or changes in existing accounting standards, practices and/or policies, and also subjective 
assumptions, estimates and judgments by management related to complex accounting matters could 
significantly affect our financial results. 

U.S. generally accepted accounting principles (GAAP) and related accounting pronouncements, 
implementation guidelines and interpretations with regard to a wide range of matters that are relevant to 
our business, such as revenue recognition, estimation of losses, determination of fair value, asset 
impairment (particularly investment securities and goodwill) and tax matters, are highly complex and 
involve many subjective assumptions, estimates and judgments. Changes in these rules or their 
interpretation or changes in underlying assumptions, estimates, or judgments could significantly change 
our reported or expected financial performance or financial condition. See Note 1 of the Consolidated 
Financial Statements for the discussion on accounting policies. 

ProAssurance is primarily a holding company of insurance subsidiaries which are required to 

comply with statutory accounting principles (SAP). SAP and its components are subject to review by the 
National Association of Insurance Commissioners (NAIC) and state insurance departments. The NAIC 
Accounting Practices and Procedures manual provides that a state insurance department may allow 
insurance companies that are domiciled in that state to depart from SAP by granting them permitted non-
SAP accounting practices. This permission may allow for more favorable treatment to competitors.  

It is uncertain whether or how SAP might be revised or whether any revisions will have a positive 

or negative effect. It is also uncertain whether any changes to SAP or its components or any permitted 
non-SAP accounting practices granted to our competitors will negatively affect our financial results or 
operations. See the Insurance Regulatory Matters section in Item 1 for the full discussion on regulatory 
matters.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
RESULTS OF OPERATIONS. 

The following discussion should be read in conjunction with the Consolidated Financial 
Statements and Notes to those statements which accompany this report. A glossary of insurance terms and 
phrases is available on the investor section of our website. Throughout the discussion, references to 
ProAssurance, “PRA,” “Company,” "we," "us" and "our" refer to ProAssurance Corporation and its 
consolidated subsidiaries. The discussion contains certain forward-looking information that involves risks 
and uncertainties. As discussed under "Forward-Looking Statements," our actual financial condition and 
operating results could differ significantly from these forward-looking statements. 

Critical Accounting Estimates 

Our Consolidated Financial Statements are prepared in conformity with U.S. generally accepted 

accounting principles (GAAP). Preparation of these financial statements requires us to make estimates 
and assumptions that affect the amounts we report on those statements. We evaluate these estimates and 
assumptions on an ongoing basis based on current and historical developments, market conditions, 
industry trends and other information that we believe to be reasonable under the circumstances. There can 
be no assurance that actual results will conform to our estimates and assumptions; reported results of 
operations may be materially affected by changes in these estimates and assumptions. 

Management considers the following accounting estimates to be critical because they involve 

significant judgment by management and the effect of those judgments could result in a material effect on 
our financial statements. 

Reserve for Losses and Loss Adjustment Expenses (reserve for losses or reserve) 

The largest component of our liabilities is our reserve for losses, and the largest component of 

expense for our operations is incurred 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 professional liability losses is inherently difficult. 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 and the personal situation of the claimant or the claimant's family, the outcome 
of jury trials, the legislative and judicial climate where the insured event occurred, general economic 
conditions and, for medical professional liability, the trend of health care costs. Professional liability 
claims are typically resolved over an extended period of time, often five years or more. The combination 
of changing conditions and the extended time required for claim resolution results in a loss cost 
estimation process that requires actuarial skill and the application of judgment, and such estimates require 
periodic revision. Our reserves are established by management after taking into consideration a variety of 
factors including premium rates, claims frequency, historical paid and incurred loss development trends, 
the effect of inflation, general economic trends, the legal and political environment, and the conclusions 
reached by our internal 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.  
Our internal actuaries perform an in-depth review of our reserve for losses on at least a semi-annual basis 
using the loss and exposure data of our insurance subsidiaries. We also engage consulting actuaries to 
review our data semi-annually and provide us with their observations regarding our data and the adequacy 
of our established reserve, believing that the consulting actuaries provide an independent view of our loss 
data as well as a broader perspective on industry loss trends.  

29 

 
 
In establishing our initial reserves for a given accident year we rely significantly on the loss assumptions 

embedded within our pricing. Because of the historically volatile nature of professional liability losses, we 
establish the initial loss estimates at a level which is approximately 8% to 10% above our pricing assumptions. 
This difference recognizes the volatility of the professional liability loss environment and the risk in determining 
pricing parameters. As each accident year matures, we analyze reserves in a variety of ways and use multiple 
actuarial methodologies in performing these analyses, including: 

  Bornhuetter-Ferguson (Paid and Reported) Method 
  Paid Development Method 
  Reported Development Method 
  Average Paid Value Method 
  Average Reported Value Method 
  Backward Recursive Method 

A brief description of each method follows.  

Bornhuetter-Ferguson Method. We use both the Paid and the Reported Bornhuetter-Ferguson methods. 

The Paid method assigns partial weight to initial expected losses for each accident year (initial expected losses 
being the first established case and IBNR reserves for a specific accident year) and partial weight to paid to-date 
losses. The Reported method assigns partial weight to the initial expected losses and partial weight to current 
reported losses. The weights assigned to the initial expected losses decrease as the accident year matures. 

Paid Development and Reported Development Method. These methods use historical, cumulative losses 

(paid losses for the Paid Development Method, reported losses for the Reported Development Method) by 
accident year and develop those actual losses to estimated ultimate losses based upon the assumption that each 
accident year will develop to estimated ultimate cost in a manner that is analogous to prior years, adjusted as 
deemed appropriate for the expected effects of known changes in the claim payment environment (and case 
reserving environment for the Reported Development Method), and, to the extent necessary, supplemented by 
analyses of the development of broader industry data. 

Average Paid Value and Average Reported Value Methods. In these methods, average claim cost data 

(paid claim cost for the Average Paid Value Method and reported claim cost for the Reported Value Method) is 
developed to an ultimate average cost level by report year based on historical data. Claim counts are similarly 
developed to an ultimate count level. The average claim cost (after rounding and adjustment, if necessary, to 
accommodate report year data that is not considered to be predictive) is then multiplied by the ultimate claim 
counts by report year to derive ultimate loss and ALAE. 

Backward Recursive Development Method. This method is an extrapolation on the movements in case 

reserve adequacy in order to estimate unpaid loss costs. Historical data showing incremental changes to case 
reserves over progressive time periods is used to derive factors that represent the ratio of case reserve values at 
successive maturities. Historical claims payment data showing the additional payments in progressive time 
periods is used to derive factors that represent the portion of a case reserve paid in the following period. Starting 
from the most mature period, after which all the case reserve is paid and the case reserve is exhausted, the next 
prior ultimate development factor for the prior case reserve can be calculated as the case factor times the 
established ultimate development factor plus the paid factor. For each successive prior maturity, the ultimate 
development factor is calculated similarly. The result of multiplying the ultimate development factor times the 
case reserve is the total indicated unpaid amount.  

Generally, methods such as the Bornhuetter-Ferguson method are used on more recent accident years 

where we have less data on which to base our analysis. As time progresses and we have an increased amount of 
data for a given accident year, we begin to give more confidence to the development and average methods, as 
these methods typically rely more heavily on our own historical data. Each of these methods treats our 
assumptions differently, and thus provides a different perspective for our reserve review. 

The various actuarial methods discussed above are applied in a consistent manner from period to period. 

In addition, we perform statistical reviews of claims data such as claim counts, average settlement costs and 
severity trends. 

30 

 
 
We segment our reserves by accident year, which is the year in which the claim becomes our liability. 

As claims are incurred (reported) and claim payments are made, they are aggregated by accident year for 
analysis purposes. We also segment our reserves by reserve type: case reserves and IBNR reserves. Case 
reserves are established by our claims department based upon the particular circumstances of each reported 
claim and represent our estimate of the future loss costs (often referred to as expected losses) that will be paid on 
reported claims. Case reserves are decremented as claim payments are made and are periodically adjusted 
upward or downward as estimates regarding the amount of future losses are revised; reported loss is the case 
reserve at any point in time plus the claim payments that have been made to date. IBNR reserves represent our 
estimate of losses that have been incurred but not reported to us and future developments on losses that have 
been reported to us.  

In performing these analyses we partition our business by coverage type, geography, layer of coverage 

and accident year. This procedure is intended to balance the use of the most representative data for each 
partition, capturing its unique patterns of development and trends. For each partition, the results of the various 
methods, along with the supplementary statistical data regarding such factors as the current economic 
environment, are used to develop a point estimate based upon management’s judgment and past experience. The 
process of selecting the point estimate from the set of possible outcomes produced by the various actuarial 
methods is based upon the judgment of management and is not driven by formulaic determination. For each 
partition of our business, we select a point estimate with due regard for the age, characteristics and volatility of 
the partition of the business, the volume of data available for review and past experience with respect to the 
accuracy of estimates. This series of selected point estimates is then combined to produce an overall point 
estimate for ultimate losses. 

We also utilize these selected point estimates of ultimate losses to develop estimates of ultimate losses 

recoverable from reinsurers, based on the terms of our reinsurance agreements. An overall estimate of the 
amount receivable from reinsurers is determined by combining the individual estimates. Our net reserve 
estimate is the sum of the gross reserve point estimate and the estimated reinsurance recovery. 

We have modeled implied reserve ranges around our single point net reserve estimates for our 

professional liability business assuming different confidence levels. The ranges have been developed by 
aggregating the expected volatility of losses across partitions of our business to obtain a consolidated 
distribution of potential reserve outcomes. The aggregation of this data takes into consideration the correlation 
among our geographic and specialty mix of business. The result of the correlation approach to aggregation is 
that the ranges are narrower than the sum of the ranges determined for each partition. 

We have used this modeled statistical distribution to calculate an 80% and 60% confidence interval for 

the potential outcome of our net reserve for losses. The high and low end points of the distributions are as 
follows: 

80% Confidence Level 
60% Confidence Level 

Low End Point 
$1.622 billion 
$1.767 billion 

Carried Net Reserve High End Point 

$2.137 billion 
$2.137 billion 

$2.718 billion 
$2.474 billion 

The claims environment in which we and others in our industry operate is inherently uncertain. The 

development of a statistical distribution models the uncertainty as well as the limited predictive power of past 
loss data. The distributions represent an estimate of the range of possible outcomes and should not be confused 
with a range of best estimates. Given the number of factors considered, it is neither practical nor meaningful to 
isolate a particular assumption or parameter of the process and calculate the impact of changing that single item.

Any change in our estimate of losses is reflected in then-current operations. Due to the size of our 

reserve for losses, even a small percentage adjustment to these estimates could have a material effect on our 
results of operations for the period in which the adjustment is made. 

Reinsurance 

We use insurance and reinsurance (collectively, "reinsurance") to provide capacity to write larger limits 
of liability, to provide protection against losses in excess of policy limits, and to stabilize underwriting results in 
years in which higher losses occur. The purchase of reinsurance does not relieve us from the ultimate risk on our 
policies, but it does provide reimbursement for certain losses we pay. 

We evaluate each of our ceded reinsurance contracts at inception to confirm that there is sufficient risk 

transfer to allow the contract to be accounted for as reinsurance under current accounting guidance. At 
December 31, 2010 all ceded contracts are accounted for as risk transferring contracts. 

Our receivable from reinsurers on unpaid losses and loss adjustment 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 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. Appropriate reserves are established for any balances we believe may not be 
collected. 

Given the uncertainty of the ultimate amounts of our losses, our estimates of losses and related amounts 

recoverable may vary significantly from the eventual outcome. Also, we estimate premiums ceded under 
reinsurance agreements wherein the premium due to the reinsurer, subject to certain maximums and minimums, 
is based in part on losses reimbursed or to be reimbursed under the agreement. Any adjustments 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. 

Our risk retention level is dependent 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 within each state. We purchase 
reinsurance from a number of companies to mitigate concentrations of credit risk. We utilize a reinsurance 
broker to assist us in the analysis of the credit quality of our reinsurers. We base our reinsurance buying 
decisions on an evaluation of the then-current financial strength, rating and stability of prospective reinsurers. 
However, the financial strength of our reinsurers, and their corresponding ability to pay us, may change in the 
future due to circumstances or events we cannot control or anticipate. 

We have not experienced significant collection difficulties due to the financial condition of any 

reinsurer; however, periodically, reinsurers may dispute our claim for reimbursement from them. 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 a substantial portion of our investments at fair value as shown in the table below. The 

distribution of our investments based on GAAP fair value hierarchies is as follows: 

Fair Value 
Cost or cash surrender value 
Total Investments 

Distribution by 
GAAP Fair Value Hierarchy 
Level 2 
90% 

Level 3 
1% 

Level 1 
5% 

December 31, 2010 
Total Investments 
96% 
4% 
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 
securities 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 internally, we utilize independent pricing services to assist us in establishing fair values. The pricing 
services provide fair values based on exchange traded prices, if available. If an exchange traded price is not 
available, the pricing services, if possible, provide a fair value that is based on multiple broker/dealer quotes or 
that has been developed using pricing models. Pricing models vary by asset class and utilize currently available 
market data for securities comparable to ours to estimate the fair value for our security. The pricing services 
scrutinize market data for consistency with other relevant market information before including the data in the 
pricing models. The pricing services disclose the types of pricing models used and the inputs used for each asset 
class. Determining fair values using these pricing models requires the use of judgment to identify appropriate 
comparable securities and to choose a valuation methodology that is appropriate for the asset class and available 
data.  

The pricing services provide a single value per instrument quoted. We review the values provided for 
reasonableness each quarter by comparing market yields generated by the supplied price versus market yields 
observed in the market place. If a supplied value is deemed unreasonable, we discuss the valuation in question 
with the pricing service and will make adjustments if deemed necessary. To date, we have not adjusted any 
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. 

As of December 31, 2010, fair values for our equity and a portion of our short-term securities have been 

determined using an exchange traded price. 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. 

With the exception of certain government bonds, 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. A large portion of our fixed income securities are valued at fair value using 
available market information. In accordance with GAAP, for disclosure purposes we classify any securities that 
have been valued based on multiple market observable inputs as Level 2 securities. 

When a pricing service does not provide a value, 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. In accordance with GAAP, for disclosure purposes we classify 
securities that are valued using limited observable inputs as Level 3 securities.

We hold interests in private investment funds which hold debt and equity securities. We value these 

investments, which at December 31, 2010 total $25.1 million or approximately 1% of total investments, based 
on quarterly net asset values provided to us by fund managers, which approximate fair value. In accordance with 
GAAP, for disclosure purposes we classify interests valued in this manner as Level 3 securities. 

Our investments that are not valued at fair value include: 

 

Interests in private investment funds having a carrying value of $31.2 million at December 
31, 2010; valued at cost. 

  Business owned life insurance policies having a carrying value of $50.5 million at 

 

December 31, 2010, valued at cash surrender value.  
Interests in tax credit partnerships having a carrying value of approximately $60.2 million at 
December 31, 2010; valued under the equity method.  

  Other business interests having a carrying value of $3.4 million at December 31, 2010; 
valued under the equity method based on the latest financial statements of the entity. 

  Federal Home Loan Bank capital stock having a carrying value of $5.2 million at December 

31, 2010; valued at cost. 

Investment Impairments 

We evaluate our investments on at least a quarterly basis for declines in fair value that represent other-
than-temporary impairments (OTTI). In all instances we consider an impairment to be an other-than-temporary 
impairment if we intend to sell the security or if we believe we will be required to sell the security before we 
fully recover the amortized cost basis of the security. Otherwise, we consider various factors in our evaluation, 
depending upon the type of security, as discussed below. 

For equity securities, we consider the following: 

 

 

the length of time for which the fair value of the investment has been less than its recorded 
basis; 
the financial condition and near-term prospects of the issuer underlying the investment, 
taking into consideration the economic prospects of the issuer's industry and geographical 
region, to the extent that information is publicly available;  
the historical and implied volatility of the fair value of the security; and 

 
  our ability and intent to hold the investment for a period of time sufficient to allow for any 

anticipated recovery in fair value. 

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 

 
 
  extent to which the decline in fair value is attributable to credit risk specifically associated 

with an investment or its issuer; 

  our internal assessments and those of our external portfolio managers regarding specific 

 

circumstances surrounding an investment, which can cause us to believe the investment is 
more or less likely to recover its value than other investments 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 ability and intent to hold the investment for a period of time sufficient to allow for any 

anticipated recovery in fair value. 

34 

 
 
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 matters that will affect 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 investments in private investment funds for OTTI by considering whether there has 

been a decline in fair value below the recorded value. We receive reports from the funds at least quarterly which 
provide us a net asset value (NAV) for our interest in the fund. The NAV is based on the fair values of securities 
held by the fund as determined by the fund manager. Determining whether there has been a decline in fair value 
involves assumptions and estimates. We consider the most recent NAV provided, the performance of the fund 
relative to the market, the stated objectives of the fund, and cash flows expected from the fund and audit results 
in considering whether an OTTI exists. 

Our investments in tax credit partnerships are evaluated for OTTI by comparing cash flow projections 

of future operating results of the underlying projects generating the tax credits to our recorded basis, and 
considering our ability to utilize the tax credits from the investments. 

We also evaluate our holdings of Federal Home Loan Bank (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 reported operating results of the current period. 

Deferred Policy Acquisition Costs 

Policy acquisition costs (primarily commissions, premium taxes and underwriting salaries) which are 
directly related to the 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. 

Deferred Taxes 

Deferred federal income taxes arise from the recognition of temporary differences between the basis of 

assets and liabilities determined for financial reporting purposes and the basis determined for income tax 
purposes. Our temporary differences principally relate to loss reserves, unearned premiums, deferred policy 
acquisition costs, unrealized investment gains (losses) and investment impairments. Deferred tax assets and 
liabilities are measured using the enacted tax rates expected to be in effect when such benefits are realized. We 
review our deferred tax assets quarterly for impairment. If we determine that it is more likely than not that some 
or all of a deferred tax asset will not be realized, a valuation allowance is recorded to reduce the carrying value 
of the asset. In assessing the need for a valuation allowance, management is required to make certain judgments 
and assumptions about our future operations based on historical experience and information as of the 
measurement period regarding reversal of existing temporary differences, carryback capacity, future taxable 
income (including its capital and operating characteristics) and tax planning strategies. 

Goodwill 

We make at least an annual assessment as to whether the value of our goodwill asset is impaired. 

Management evaluates the carrying value of goodwill annually during the fourth quarter and before the annual 
evaluation if events occur or circumstances change that would more likely than not reduce the fair value below 
the carrying value. We evaluate goodwill as one reporting unit because we operate in 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 our 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 in 2010, 2009, and 2008 that the fair value of our reporting 
unit exceeded the carrying value and no adjustment to impair goodwill was necessary.

ProAssurance Overview 

We are an insurance holding company and our operating results are primarily derived from the 
operations of our insurance subsidiaries, which principally write medical and other professional liability 
insurance.  

Corporate Strategy 

Our mission is to be the preferred source of professional liability protection by providing unparalleled 

claims defense, highly responsive customer service and innovative risk management while maintaining our 
commitment to long-term financial strength. According to A.M. Best’s analysis of 2009 data, we are the largest 
independently publicly traded medical professional liability specialist insurance writer in the nation. Our 
customer focus combined with our financial strength, strong reputation and proven ability to manage claims, has 
enabled us to expand our operations while maintaining profitability. We have successfully acquired and 
integrated companies and books of business in the past and expect to be able to continue to grow through 
acquisitions, although we cannot predict the pace of those transactions with any certainty. We emphasize 
disciplined underwriting and prudent pricing in order to achieve profitability as opposed to emphasizing 
premium growth and achieving market share gain at any cost. In addition to prudent risk selection and pricing, 
we seek to control our underwriting results through effective claims management, and have fostered a strong 
culture of defending non-meritorious claims. We differentiate ProAssurance from many other national writers 
by tailoring our claims handling to the legal climate of each state. 

Through our market-based underwriting and claims office structure, we develop a deep understanding of 

local market conditions, which enables us to respond to changes in the liability climate and adapt our 
underwriting and claims strategies as needed. Our market-based focus allows us to maintain active relationships 
with our customers, understand the importance of the professional identity and reputation of our insureds and 
thus be more responsive to their needs. We use advisory boards and operational committees to help us better 
understand the challenges facing our insureds and ways in which we can assist them. We employ medical and 
legal professionals throughout our organization, especially on our senior management team, in order to add to 
our understanding of the medical/legal environment. We emphasize our pledge that each insured professional 
will be treated fairly in all of our conduct with them and that all of our business actions will be informed by the 
core values that guide our organization: integrity, respect, doctor involvement in healthcare insurance activities, 
collaboration, communication and enthusiasm. Our strategy allows us to compete on a basis other than price 
alone.  

We have sustained our financial stability during difficult market conditions through responsible pricing 

and loss reserving practices and through conservative investment practices. We are committed to maintaining 
prudent operating and financial leverage and conservatively investing our assets. We recognize the importance 
that our customers and producers place on the financial strength of our principal insurance subsidiaries and we 
manage our business to protect our financial security. 

36 

 
 
 
 
We consider a number of ratios in measuring our performance, including the following: 

  The net loss ratio is calculated as net losses incurred divided by net premiums earned and is an 

indicator of underwriting profitability. 

  The underwriting expense ratio is calculated as underwriting, policy acquisition and operating 

expenses incurred divided by net premiums earned and is an indicator of underwriting profitability. 
  The combined ratio is the sum of the underwriting expense ratio and the net loss ratio and measures 

underwriting profitability. 

  The investment income ratio is calculated as net investment income divided by net premiums earned 

and measures the contribution investment earnings provides to our overall profitability. 

  The operating ratio is the combined ratio, less the investment income ratio. This ratio incorporates 

the effect of investment income and underwriting profitability. 

  Return on equity is calculated as net income for the period divided by the average of beginning and 

ending shareholders’ equity.  This ratio measures our overall after-tax profitability from 
underwriting and investment activity and shows how efficiently invested capital is being used. 

We particularly focus on our combined ratio and investment returns, both of which directly affect our return on 
equity (ROE). We target a long-term average ROE of 12% to 14%. 

Our emphasis on rate adequacy, selective underwriting, effective claims management and prudent 
investments is a key factor in our achievement of our ROE target. We closely monitor premium revenues, losses 
and loss adjustment costs, and underwriting and policy acquisition expenses. Our overall investment strategy is 
to focus on maximizing current income from our investment portfolio while maintaining safety, liquidity, 
duration and portfolio diversification. While we engage in activities that generate other income, such activities, 
principally fee and agency services, do not constitute a significant use of our resources or a significant source of 
revenues or profits. 

37 

 
 
Growth Opportunities and Outlook 

We expect our long-term growth to come through controlled expansion of our existing operations. We 

also look to expand through the acquisition of other specialty insurance companies or books of business; 
however, such expansion is often opportunistic and cannot be predicted.  

We continue to face price-based competition in virtually all of our markets. Some competitors, 
particularly when targeting new markets, offer coverage at rates we believe to be inadequate for the risk being 
accepted. A continuing competitive trend is physicians and hospitals seeking to lower their costs using 
alternative risk transfer approaches such as self insurance and risk sharing pools. In recent years we have also 
seen a trend toward hospitals purchasing physician practices. In response to these trends, we offer products 
designed to provide greater risk sharing options to hospitals and large physician groups. 

As a result of our branding campaign, “Treated Fairly”, recent acquisitions, and improvements in loss 

cost trends that have allowed us to reduce rates in certain markets, we were able to grow our physician count in 
2010 by 10%.  We believe our emphasis on fair treatment of our insureds and other important stakeholders has 
enhanced our market position and differentiated us from other insurers. We will continue to use “Treated Fairly” 
in all of our activities, and we believe that as we reach more customers with this message we will continue to 
improve retention and add new insureds. 

We have been a consistent acquirer of other physician insurers for a number of years, including APS. In 

addition, in 2009 we expanded our insured base in new directions by acquiring a leading insurer of podiatric 
physicians that operates on a national basis, an insurer focused on the legal professional liability market, and an 
agency largely focused on the professional liability needs of allied health care providers. We continue to see 
new opportunities from each of the acquisitions and believe each will provide organic growth through expansion 
in their existing markets and relationships.  

Accounting Changes  

Investment Disclosures; Other-than-temporary Impairments 

Effective for interim and annual reporting periods ending on or after June 15, 2009, the Financial 

Accounting Standards Board revised GAAP to require expanded disclosures related to investments in debt and 
equity securities. Guidance regarding other-than-temporary impairments was also revised. Previous investment 
guidance required that an impairment of a debt security be considered as other-than-temporary unless 
management could assert both the intent and the ability to hold the impaired security until recovery of value. 
The revised impairment guidance specifies that an impairment be considered as other-than-temporary unless an 
entity can assert that it has no intent to sell the security and that it is not more likely than not that the entity will 
be required to sell the security before recovery of its anticipated amortized cost basis.  

The guidance also establishes the concept of credit loss. Credit loss is defined as the difference between 
the present value of the cash flows expected to be collected from a debt security and the amortized cost basis of 
the security. The new guidance states that “…in instances in which a determination is made that a credit 
loss exists but the entity does not intend to sell the debt security and it is not more likely than not that the entity 
will be required to sell the debt security before the anticipated recovery of its remaining amortized cost basis” an 
impairment is to be separated into (a) the amount of the total impairment related to the credit loss and (b) the 
amount of total impairment related to all other factors. The credit loss component of the impairment is to be 
recognized in income of the current period. The non-credit component is to be recognized as a part of other 
comprehensive income (OCI). Transition provisions require a cumulative effect adjustment to reclassify the 
non-credit component of a previously recognized other-than-temporary impairment from retained earnings to 
accumulated other comprehensive income “…if an entity does not intend to sell and it is not more likely than 
not that the entity will be required to sell the security before recovery of its amortized cost basis.” We adopted 
the revised guidance on the date it became effective, which for PRA was April 1, 2009. On the date of adoption 
our debt securities included non-credit impairment losses previously recognized in earnings of approximately 
$5.4 million. In accordance with the transition provisions of the revised guidance, we reclassified these non-
credit losses, net of tax, from retained earnings to accumulated other comprehensive income as of April 1, 2009,

comprehensive income). 

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 it has no other business operations, dividends from its operating subsidiaries represent a 
significant source of funds for its obligations, including debt service. At December 31, 2010, we held cash and 
investments of approximately $152.8 million outside of our insurance subsidiaries that are available for use 
without regulatory approval. Our insurance subsidiaries, in aggregate, are permitted to pay dividends of 
approximately $248 million during 2011 without prior approval. However, the payment of any dividend requires 
prior notice to the insurance regulator in the state of domicile and the regulator may prevent the dividend if, in 
its judgment, payment of the dividend would have an adverse effect on the surplus of the insurance subsidiary. 
In 2010 our insurance subsidiaries paid dividends of $231.0 million, $17.2 million of which was an approved 
extraordinary dividend. 

Acquisitions 

On November 30, 2010, we acquired 100% of the outstanding shares of American Physicians Service 

Group, Inc. (APS), whose primary operating entity is American Physicians Insurance Company (API), in a 
transaction valued at $237 million including cash paid of $233 million and liabilities assumed of $4 million. 
APS provides professional liability insurance primarily to physicians in Texas and reported gross written 
premium of $61 million for the year ended December 31, 2010, $5 million of which is included in ProAssurance 
consolidated premium for 2010.  

On April 1, 2009 we acquired Podiatry Insurance Company of America and subsidiaries (PICA) through 
a cash sponsored demutualization as a means of expanding our professional liability insurance operations. PICA 
provides professional liability insurance primarily to podiatric physicians, chiropractors and other healthcare 
providers throughout the United States. We purchased all of PICA’s outstanding stock created in the 
demutualization for $135 million in cash, of which $15 million was a surplus contribution to be used to provide 
renewal premium credits to eligible policyholders over a three year period beginning in 2010. PACO Assurance 
Company, Inc. (PACO), formerly wholly owned by PICA, is now wholly owned by a ProAssurance holding 
company. For simplicity of presentation, our discussions that follow combine PACO and PICA results for both 
2010 and 2009. The combined results are referred to as PICA. 

In the first quarter of 2009 we acquired 100% of the outstanding shares of Mid-Continent General 

Agency, Inc., now ProAssurance Mid-Continent Underwriters, Inc., (Mid-Continent), and Georgia Lawyers 
Insurance Company (Georgia Lawyers), since merged with our subsidiary ProAssurance Casualty Company, as 
a means of expanding our professional liability business. These acquisitions were not material to ProAssurance 
individually or in the aggregate. 

See Note 2 of the Notes to the Consolidated Financial Statements for detailed information regarding the 

2010 and 2009 acquisitions, including a summarized listing of the assets acquired and liabilities assumed. 

Cash Flows 

The principal components of our operating cash flows are the excess of net investment income and 

premiums collected over losses paid and operating costs, including income taxes. Timing delays exist between 
the collection of premiums and the payment of losses associated with the premiums. Premiums are generally 
collected within the twelve-month period after the policy is written while our claim payments are generally paid 
over a more extended period of time. Likewise, timing delays exist between the payment of claims and the 
collection of any associated reinsurance recoveries. 

39 

 
 
 
 
Our operating activities provided positive cash flows of approximately $139.2 million and $75.4 million 

for the years ended December 31, 2010 and 2009, respectively. Operating cash flows for 2010 and 2009 
compare as follows:

(1)  The decrease in premium receipts reflects the decline in gross written premium, exclusive of the 

premium decline that is attributable to policies written on a two-year term. The two-year term affects 
premiums written but has no effect on the timing of premium receipts. Additionally, approximately $3 
million of the decrease in premium receipts is due to premium credits granted to PICA policyholders as 
part of the acquisition. 

(2)  Reinsurance contracts are generally for premiums written in a specific annual period, but can remain in 
effect until all claims under the contract have been resolved. Some contracts require annual settlements 
while others require settlement only after a number of years have elapsed, thus the amounts paid can 
vary widely from period to period. 

(3)  The decrease in losses reflects lower paid losses at our subsidiaries other than PICA of approximately 
$69 million offset by an increase in PICA losses paid of $18 million. The PICA increase is principally 
due to an additional three months of PICA activity in 2010. The timing of our loss payments varies 
from period to period because the process for resolving claims is complex and occurs at an uneven 
pace depending upon the circumstances of the individual claim. 

(4)  The timing of reinsurance recoveries varies from period to period and can depend upon the terms of the 
applicable reinsurance agreement, the nature of the underlying claim and the timing and amount of 
underlying loss payments. 

(5)  In 2009 we paid a judgment in favor of Columbia Hospital for Women Medical Center, Inc. (CHW) 

(the CHW Judgment) that was entered against our subsidiary, ProAssurance National Capital Insurance 
Company (PRA National), prior to our acquisition of PRA National. We established a liability related 
to the judgment and accrued post trial interest at the time PRA National was acquired in 2005. 

(6)  The increase in tax payments primarily reflects: 

  A final estimated payment for the 2009 tax year (paid in 2010) that was lower than the final 

estimated tax payment for the 2008 tax year (paid in 2009). In 2008 a large portion of taxable 
income for the year was earned in the fourth quarter; in 2009 taxable income was earned more 
ratably throughout the year. 

  Estimated payments for the 2010 tax year that are higher than those paid for the 2009 tax year.  

Our 2009 tax liability was significantly reduced by tax deductions, primarily the CHW Judgment 
and losses on the sale of impaired securities, that did not reduce 2009 GAAP income. Our 2010 
payments also include an estimated federal tax payment of $3.4 million that relates to the APS pre-
acquisition period.

A detailed listing of our investment holdings as of December 31, 2010 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 $100 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 the Federal Home Loan Banking system. However, given the relatively short 
duration of our investments, we do not foresee any such shortfall.  

Our investment portfolio continues to be primarily composed of high quality fixed income 

securities with approximately 97% of our fixed maturities being investment grade securities as 
determined by national rating agencies. The weighted average effective duration of our fixed maturity 
securities at December 31, 2010 is 4.1 years; the weighted average effective duration of our fixed 
maturity securities combined with our short-term securities is 4.0 years.  

We decreased our state and municipal bond holdings by approximately $200 million in 2010 to 

reduce our exposure to municipal bonds, particularly for those rated below AA-. Excluding the impact of 
guarantees by insurers, our state and municipal bond holdings have a weighted average credit rating of 
AA at December 31, 2010. 

We reduced our BOLI investment in 2010 by redeeming approximately $16 million of its cash 

surrender value. This redemption triggered an additional tax liability of approximately $1.3 million, 
which we recognized during 2010. 

We invested $60 million in tax credit limited partnerships during 2010 ($47 million of which is 
committed but unfunded at December 31, 2010). These partnerships are designed to provide returns via 
the transfer of tax operating losses and tax credits to their partners. All of the interests are accounted for 
using the equity method. We plan to increase our investment in tax credit partnerships in 2011 by up to an 
additional $40 million subject to identifying opportunities that meet our investment criteria. 

Losses 

The following table, known as the Analysis of Reserve Development, presents information over 

the preceding ten years regarding the payment of our losses as well as changes to (the development of) 
our estimates of losses during that time period. As noted in the table, ProAssurance has completed various 
acquisitions over the ten year period, which have affected original and re-estimated gross and net reserve 
balances as well as loss payments.  

The table includes losses on both a direct and an assumed basis and is net of reinsurance 

recoverables. The gross liability for losses before reinsurance, as shown on the balance sheet, and the 
reconciliation of that gross liability to amounts net of reinsurance are reflected below the table. We do not 
discount our reserve for losses to present value. Information presented in the table is cumulative and, 
accordingly, each amount includes the effects of all changes in amounts for prior years. The table presents 
the development of our balance sheet reserve for losses; it does not present accident year or policy year 
development data. Conditions and trends that have affected the development of liabilities in the past may 
not necessarily occur in the future. Accordingly, it is not appropriate to extrapolate future redundancies or 
deficiencies based on this table. 

42 

 
 
The following may be helpful in understanding the Analysis of Reserve Development: 

–  The line entitled “Reserve for losses, undiscounted and net of reinsurance recoverables” 
reflects our reserve for losses and loss adjustment expense, less the receivables from 
reinsurers, each as reported in our consolidated financial statements at the end of each 
year (the Balance Sheet Reserves). 

–  The section entitled “Cumulative net paid, as of” reflects the cumulative amounts paid as 
of the end of each succeeding year with respect to the previously recorded Balance Sheet 
Reserves. 

–  The section entitled “Re-estimated net liability as of” reflects the re-estimated amount of 
the liability previously recorded as Balance Sheet Reserves that includes the cumulative 
amounts paid and an estimate of additional liability based upon claims experience as of 
the end of each succeeding year (the Net Re-estimated Liability).  

–  The line entitled "Net cumulative redundancy (deficiency)" reflects the difference 

between the previously recorded Balance Sheet Reserve for each applicable year and the 
Net Re-estimated Liability relating thereto as of the end of the most recent fiscal year.

In each year reflected in the table, we have estimated our reserve for losses utilizing the 
management and actuarial processes discussed in critical accounting estimates. Factors that have 
contributed to the variation in loss development are primarily related to the extended period of time 
required to resolve professional liability claims and include the following: 

–  The medical professional liability legal environment deteriorated in the late 1990’s. 

Beginning in 2000, we recognized adverse trends in claim severity causing increased 
estimates of certain loss liabilities. As time has progressed, the reserves initially 
established for those years have continued to develop unfavorably. We addressed the 
adverse severity trends through increased rates, stricter underwriting and modifications to 
claims handling procedures. The expectation of increased claim severity was also 
considered in establishing our initial reserves for subsequent years. 

–  These adverse severity trends then began to moderate.  As a result, we recognized 
favorable development related to our previously established reserves primarily for 
accident years 2002 through 2008 because we have reduced our estimates of claims 
severity related to those years. Based on recent internal and industry claims data, we 
believe claims severity (i.e., the average size of a claim) is increasing at a rate slower 
than we estimated when our reserves for those years were established.  

  A general decline in claim frequency has also been a contributor to favorable loss 

development.  A significant portion of our policies through 2003 were issued on an 
occurrence basis, and a smaller portion of our ongoing business results in occurrence-like 
exposure due to the issuance of extended reporting endorsements. As claim frequency 
declined, the number of reported claims related to these coverages were less than 
originally expected.

At December 31, 2010 our gross reserve for losses included case reserves of approximately $1.1 
billion and IBNR reserves of approximately $1.3 billion. Our consolidated reserve for losses on a GAAP 
basis exceeds the combined reserves of our insurance subsidiaries on a statutory basis by approximately 
$78.9 million, which is principally due to the portion of the GAAP reserve for losses that is reflected for 
statutory accounting purposes as unearned premiums. These unearned premiums are applicable to 
extended reporting endorsements (“tail” coverage) issued without a premium charge upon death, 
disability, or retirement of an insured.

Reinsurance 

We use reinsurance to provide capacity to write larger limits of liability, to provide protection 
against losses in excess of policy limits, and to stabilize underwriting results in years in which higher 
losses occur. The purchase of reinsurance does not relieve us from the ultimate risk on our policies, but it 
does provide reimbursement from the reinsurer for certain losses paid by us. 

We generally reinsure professional liability risks under annual treaties pursuant to which the 

reinsurer agrees to assume all or a portion of all risks that we insure above our individual risk retention of 
$1 million per claim, up to the maximum individual limit offered (currently $16 million). Historically, the 
professional liability per claim retention level has varied between 90% and 100% of the first $1 million 
and between 0% and 5% of claims exceeding those levels depending on the coverage year and the state in 
which business was written. We also insure some large professional liability risks that are above the limits 
of our basic reinsurance treaties. These risks are reinsured on a facultative basis, whereby the reinsurer 
agrees to insure a particular risk up to a designated limit. 

Our primary reinsurance agreement is negotiated annually at October 1. There was no significant 

change in the cost or structure of the agreements renewed on October 1, 2010. 

Our risk retention level is dependent 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 within 
each state. We purchase reinsurance from a number of companies to mitigate concentrations of credit risk. 
We utilize a reinsurance broker to assist us in the analysis of the credit quality of our reinsurers. We base 
our reinsurance buying decisions on an evaluation of the then-current financial strength, rating and 
stability of prospective reinsurers. However, the financial strength of our reinsurers, and their 
corresponding ability to pay us, may change in the future due to forces or events we cannot control or 
anticipate. 

We have not experienced significant collection difficulties due to the financial condition of any 

reinsurer; however, periodically, reinsurers may dispute our claim for reimbursement from them. 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 significant 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. 

The following table identifies our reinsurers from which our recoverables for both paid and 

unpaid claims (net of amounts due to the reinsurer) and our prepaid balances are $10 million or more as 
of December 31, 2010:

For the purposes of this table, all long-term debt is assumed to be settled at its contractual 

maturity and interest on variable rate long-term debt is calculated using interest rates in effect at 
December 31, 2010. The anticipated payout of loss and loss adjustment expenses is based upon our 
historical payout patterns. Both the timing and amount of these payments may vary from the payments 
indicated. Our operating lease obligations are primarily for the rental of office space and office 
equipment. 

Each of our debt instruments allows for repayment before maturity, at our option, on or after 

certain dates. For more information on our debt see Note 10 to the Consolidated Financial Statements. 

Treasury Stock 

We repurchased approximately 1.9 million common shares having a total cost of $106.3 million 

during the year ended December 31, 2010. Our Board of Directors authorized an additional $200.0 
million in November 2010 for the repurchase of common shares or the retirement of outstanding debt. At 
December 31, 2010 approximately $209.0 million in amounts authorized by the Board remains available 
for use. 

Litigation 

We are involved in various legal actions related to our insurance activities which we consider in 
our evaluation of our reserve for losses. We also have other direct actions against the company which we 
evaluate and account for as a part of our other liabilities. 

In accordance with GAAP for insurance entities, claim-related actions are considered as a part of 
our loss reserving process. We evaluate the likely outcomes from these actions giving consideration to the 
facts and laws applicable to each case, appellate issues, coverage issues, potential recoveries from our 
insurance and reinsurance programs, and settlement discussions as well as our historical claims resolution 
practices. This data is then considered in the overall evaluation of our reserve for losses. 

There are risks, as outlined in our Risk Factors in Part 1, that any of these actions could cost us 

more than our estimates. In particular, we or our insureds may receive adverse verdicts; post-trial motions 
may result in unfavorable rulings; any appeals that may be undertaken may be unsuccessful; we may be 
unsuccessful in our legal efforts to limit the scope of coverage available to insureds; and we may become 
a party to bad faith litigation over the resolution of a claim.  

For non-claim related actions, we evaluate each case separately and establish what we believe is 

an appropriate reserve based on GAAP guidance related to contingent liabilities. 

To the extent that the cost of resolving these actions exceeds our estimates, the legal actions could 

have a material effect on our results of operations in the period in which any such action is resolved.

Overview of Results–Years Ended December 31, 2010 and 2009 

Net income is $231.6 million for the year ended December 31, 2010, as compared to $222.0 million for 

the year ended December 31, 2009. Net income per diluted share is $7.20 and $6.70 for the years ended 
December 31, 2010 and 2009, respectively.  

Results from the years ended December 31, 2010 and 2009 compare as follows: 

Premiums 

Net premiums earned increased during 2010 by approximately $21.6 million or 4.3%. Three additional 

months of PICA earned premium and one month of APS earned premium generated approximately $28.2 
million of additional net earned premium. Net earned premium was increased by an additional $7.2 million 
related to the re-estimation of amounts due to reinsurers related to prior accident years. These increases were 
partially offset by other declines in earned premium principally due to non-renewals and rate reductions. 

Net Investment Income; Net Realized Investment Gains (Losses) 

Our 2010 net investment result (which includes both net investment income and earnings from 

unconsolidated subsidiaries) decreased by $4.8 million or 3.1% primarily due to a decrease in earnings from 
fixed income securities and short term investments. The decrease primarily reflects lower yields in 2010. 

Net realized investment gains increased by $4.6 million during 2010. As compared to 2009, increased 

gains from sales more than offset a $7.9 million increase in impairment losses. 

Expenses 

Net losses decreased by $10.0 million or 4.3% during 2010 due to increased favorable loss development 

of $26.7 million offset by a $16.7 million increase in current accident year losses. The increase in current 
accident year losses is primarily attributable to three additional months of PICA activity in 2010 and one 
additional month of APS activity.  

Underwriting, policy acquisition and operating expenses increased in 2010 by $18.4 million or 15.8%. 

Approximately $10.6 million of the increase is attributable to the acquisitions of PICA and APS and the 
remainder relates to various operating factors. 

Ratios 

Our net loss ratio decreased in 2010 by 3.8 points. Higher favorable development decreased the ratio by 

3.4 points. 

Our underwriting expense ratio increased in 2010 by 2.7 points. The increase is attributable both to the 

acquisitions of PICA and APS and increased policy acquisition and operating costs. 

Our operating ratio increased in 2010 by 1.0 point reflecting a decline in the investment ratio of 
approximately 2.1 points partially offset by the combined 1.1 point decrease in the net loss and expense ratios. 

Return on equity is 13.0% for 2010 and 14.2% for 2009. 

Book Value per Share 

Our book value per share at December 31, 2010 is $60.35 compared to $52.59 at December 31, 2009. 
The change reflects our 2010 income, the increase in accumulated other comprehensive income and a benefit 
from treasury share purchases. Due to the size of our Shareholders’ Equity (approximately $1.9 billion at 
December 31, 2010), the growth rate of our book value per share may slow. The past growth rates of our book 
value per share do not necessarily predict similar future results. 

49 

 
 
 
Non-GAAP Financial Measures 

Operating income is a non-GAAP financial measure that is widely used to evaluate the performance of 

insurance entities. Operating income excludes the after-tax effects of realized gains or losses, guaranty fund 
assessments and debt retirement loss. 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:

that is after the acquisition date. Our 2010 operating results include twelve months of PICA activity and one 
month of APS activity. Our 2009 operating results include nine months of PICA activity but do not include any 
APS results. In many of the supporting tables that follow, the effect of the additional 2010 PICA/APS activity is 
shown separately with the column header “Additional PICA/APS Activity”.

Premiums 

Gross Premiums Written 

Changes in our premium volume are driven by three primary factors: (1) our retention of existing 

business, (2) the amount of new business we are able to generate, including business that comes to PRA as a 
result of acquisitions, and (3) the premium charged for business that is renewed, which is affected both by rates 
charged and by the amount and type of coverage an insured chooses to purchase. The professional liability 
market remains competitive with some competitors choosing to compete primarily on price.

Physician Premiums 

Physician premiums continue to be our primary revenue source and comprise 78% and 80% of our gross 

premiums written in 2010 and 2009, respectively.  

Approximately $22.6 million of the overall decrease in physician premiums is due to changes in our 

renewal patterns. We began offering policy renewals for a two-year term (as opposed to a one-year term) to our 
physician insureds in one selected jurisdiction during late 2008. The premium associated with both policy terms 
is included in written premium in the period the policy is written, which increases gross written premium in the 
year the policy is written but reduces gross written premium in the following year. Approximately $16.1 million 
of the gross written premium decline during 2010 is attributable to the policies written on a two-year term. Also, 
during 2009, in order to more evenly distribute renewals throughout the year, we offered early renewal to a 
number of insureds who otherwise would have had a first quarter 2010 renewal date. Approximately $6.5 
million of the 2010 decrease in physician premiums is attributable to the shift in renewal dates. 

Excluding APS, our retention rate for our physician business for 2010 is 90%, which is unchanged from 
2009. Retention rates are affected by a number of factors. We may choose not to renew an insured as a result of 
our underwriting evaluation. Insureds terminate coverage because they have retired or have otherwise ceased to 
practice medicine. We may also lose insureds to competitors or to self-insurance mechanisms (often when 
physicians join hospital-based practice groups) due to pricing or other issues.  

In the aggregate, charged rates for our physician business renewed in 2010 showed no change. In 2009 

charged rates showed an average 2% decrease. In general, charged rates at our PICA subsidiary increased in 
2010 as compared to 2009, while rates at our other insurance subsidiaries decreased. Our charged rates include 
the effects of filed rates, surcharges and discounts. Despite competitive pressures, we continue to base our rates 
on expected losses, as indicated by our historical loss data and available industry loss data. We are committed to

a rate structure that will allow us to fulfill our obligations to our insureds, while generating competitive returns 
for our shareholders. 

We wrote approximately $16.0 million of new physician business during 2010.  

Non-physician Premiums 

Our non-physician healthcare providers are primarily dentists, chiropractors, optometrists, and allied 

health professionals. The 2010 increase is primarily related to allied health coverages, but also includes 
additional premium of $1.2 million generated by a targeted marketing campaign to optometrists. 

Hospital and facility premiums decreased during 2010. The decline reflects many of the same 

competitive pressures that are affecting our business overall. 

Non-physician “other” premiums are primarily legal professional liability premiums, but also includes 

other types of general liability premiums. The $1.1 million increase in premium volume for 2010 principally 
relates to our legal professional liability premiums. 

Non-continuing in the above table separately identifies premium generated by certain types of 

miscellaneous liability coverages which we no longer provide. We do expect minimal premiums from these 
coverages in future periods. 

Tail Premiums 

We separately report tail premiums because we offer extended reporting endorsement or "tail" policies 
to insureds that are discontinuing their claims-made coverage with us. The amount of tail premium written and 
earned can vary widely from period to period.

Premiums Earned 

Because premiums are generally earned pro rata over the entire policy period, fluctuations in premiums 
earned tend to lag those of premiums written. Generally, our policies carry a term of one year, but as discussed 
above, we renew certain policies with a two-year term. Tail premiums are generally 100% earned in the period 
written because the policies insure only incidents that occurred in prior periods and are not cancellable.  

The acquisition of APS is expected to increase 2011 earned premium by $20.4 million related to APS 

premiums written prior to the acquisition that were unearned at December 31, 2010. The premiums will be 
earned in 2011 on a pro rata basis, and are expected to affect 2011 premiums earned as follows: Q1 - $10.7 
million; Q2 - $6.8 million; Q3 - $2.6 million; Q4 - $0.3 million. 

Premiums Ceded 

Premiums ceded represent the portion of earned premiums that we pay our reinsurers for their 
assumption of a portion of our losses. The premium that we cede to our reinsurers is determined, in part, by the 
loss experience (subject to minimums and maximums) of the business ceded to them. It takes a number of years 
before all losses are known, and in the intervening period, premiums due to the reinsurers are estimated. 

Premiums ceded declined in both 2010 and 2009 ($13.4 million and $6.2 million, respectively) due to 

reductions in the estimated amounts expected to be due to reinsurers related to prior year coverages. These 
reductions had a significant effect on our reinsurance expense ratio as shown in the following table.

Excluding the effect of the changes to prior year estimates, the decrease in the reinsurance expense is 
primarily due to shifts in the mix of our business during 2010 as compared to 2009. In 2010 we discontinued 
offering certain non-physician liability policies (see discussion under Premiums), and reduced our reinsurance 
coverage related to the policies. Also, premiums earned from our legal professional liability business acquired 
from Georgia Lawyers were more heavily reinsured in 2009 than in 2010. Pre-acquisition reinsurance 
agreements were in effect in 2009 but ProAssurance reinsurance agreements with higher retention limits were in 
effect in 2010.

Net Investment Income, Equity in Earnings (Loss) of Unconsolidated Subsidiaries, Net Realized 
Investment Gains (Losses) 

Net Investment Income 

Net investment income is primarily derived from the income earned on our fixed maturity securities and 
also includes dividend income from equity securities, income from our short-term, cash equivalent investments, 
earnings from other investments and increases in the cash surrender value of business owned life insurance 
contracts. Investment fees and expenses are deducted from investment income.

Fixed Maturities. The decrease in income in 2010 reflects lower yields, partially offset by higher 

average investment balances. 

The overall yield on our portfolio declined because we were not able to reinvest proceeds from 
maturities, pay-downs and sales at rates comparable to expiring rates while maintaining our asset quality and the 
duration of our portfolio. Average yields for our available-for-sale fixed maturity securities during 2010 and 
2009 are as follows:

2009

The level of our investment in fixed maturity securities varies depending upon a number of factors, 
including, among others, our operating cash needs, anticipated shifts in credit markets, the attractiveness of 
other investment alternatives, and cash needed for acquisitions or other capital purposes. In 2010 as compared to 
2009, our average investment in fixed maturities increased by approximately 3%.  

Short-term Investments. The decrease in earnings for 2010 reflects a decline in short-term interest rates 

and lower average invested balances.

We hold interests in certain private investment funds that derive earnings from trading portfolios. The 

performance of these funds is affected by the volatility of equity and credit markets. One fund, shown separately 
in the table, was liquidated in July 2010. 

We have acquired an interest in a development stage limited liability company that will, in time, engage 

in active business operations. While we expect this investment to provide a positive return over time, we 
anticipate operating losses during the start up phase, expected to last another twelve months. Our potential for 
loss is limited to the carrying amount of our investment, currently $3.4 million. 

We began investing in tax credit limited partnerships in 2010. Our tax credit investments are designed to 

generate investment returns by providing tax benefits to fund investors in the form of net operating losses and 
tax credits. During 2010 our tax credit partnerships generated a tax benefit of approximately $1.0 million. 

Tax Equivalent Investment Result 

We  believe  that  to  fully  understand  our  investment  returns  it  is  important  to  consider  the  tax  benefits 
associated  with  certain  investments;  therefore,  we  impute  a  tax-equivalent  investment  result  in  order  to  better 
reflect the economies of our decision to invest in certain asset classes that are either taxed at lower rates and/or 
result in reductions to our federal income tax expense.

(1) In accordance with GAAP, all OTTI losses prior to April 1, 2009 were recognized in earnings. 

We have recognized impairments of $9.5 million during 2010 related to certain high-yield asset-backed 
securities. The securities were returned to our direct ownership in 2010 when our interest in a private investment 
fund was liquidated. Based on our intent to sell the securities, we have recognized all declines in fair value 
below our cost basis as other-than-temporary impairments. 

We recognized an impairment of $3.4 million in 2010 related to an interest in a private investment fund 

which we account for on a cost basis. The fund has reported realized losses on the sale of securities, and we 
have reduced the carrying value of our interest in the fund in recognition of our pro rata share of those losses. 

We recognized impairments in earnings of $3.0 million in 2010, including $1.5 million reclassified from 

OCI, related to residential mortgage-backed securities. Expected future cash flows were less than our carrying 
value for these securities; therefore, we reduced the carrying value of our interest in these securities and 
recognized the loss in our 2010 net income. 

Fair value adjustments are attributable to our election of fair value treatment for both the 2019 Note 

Payable and related interest rate swap, as discussed in Notes 3 and 9 of the Notes to the Consolidated Financial 
Statements. 

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 most indicative 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.

* Net losses as specified divided by net premiums earned. 

The increase in current accident year losses for 2010 is primarily attributable to three additional months 

of PICA activity and one month of APS activity. 

During the years ended December 31, 2010 and 2009, we recognized favorable loss development of 
$234.0 million and $207.3 million respectively, on a net basis, related to reserves established in prior years. 

The principal components of development are as follows:

Substantially all of the favorable development recognized during 2010 and 2009 relates to medical 

professional liability claims-made reserves. The favorable development for medical professional claims-made 
policies in both years is based upon observation of actual claims data that indicates that claims severity (i.e., the 
expected average cost of claims) is trending below our initial expectations. Given both the long tailed nature of 
our business and the past volatility of final claim settlement values, we are generally cautious in giving credence 
to the trends that lead to the recognition of favorable net loss development. As we conclude that sufficient 
credible data with respect to these trends exists we take appropriate actions. In the case of the claims severity 
trends, we believe it is appropriate to recognize the impact of these trends in our actuarial evaluation of prior 
period loss estimates while also remaining attentive to the past volatility of claims severity. 

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 has been the case in 2010 and 2009.

In 2009 we incurred $2.5 million in transaction-related costs associated with the purchase of PICA, 

principally for severance costs and investment banking fees. Similarly, we incurred $2.0 million in transaction-
related costs primarily in the third and fourth quarters of 2010 associated with the purchase of APS. 

The increase in policy acquisition expenses reflects the application of GAAP purchase accounting rules 
whereby the capitalized policy acquisition costs for policies written prior to the acquisition date are written off 
rather than being expensed ratably over the term of the associated insurance policy. Application of this guidance 
resulted in lower-than-normal PICA acquisition costs in 2009. Similarly, APS acquisition expenses (for the one 
month included in our 2010 results) for 2010 are lower than what would be considered normal and will increase 
gradually in 2011 as more APS earned premium is generated by policies written after the acquisition date.

Other Expense Increase 

The remaining $9.0 million increase in insurance operation expenses is primarily due to the following: 

  Expense for policy acquisition costs was higher in 2010 primarily because premium earned 

related to allied healthcare, legal and miscellaneous professional liability coverages increased in 
2010. Commission and underwriting expenses associated with these premiums are higher than 
those associated with physician premiums.  

  We recognized $2.6 million in ceding commission expense related to a captive insurance 

arrangement that was terminated in 2010. 

  We allocate our operating costs between insurance operations expense and loss adjustment 

expenses. The amount allocated to loss adjustment expense decreased by $3.5 million in 2010, 
which had the effect of increasing operating expenses.  

  Guaranty fund assessments or recoupments are not controlled by us, but do affect our results. In 
both 2010 and 2009 recoupments exceeded assessments, but the recoupment benefit was $0.8 
million greater in 2010. 

  We terminated and replaced our Employee Stock Ownership Plan during the year, resulting in 
an acceleration of vesting of participants’ accounts. This resulted in a charge of approximately 
$0.8 million during the year. The new plan put in place provides for vesting of benefits over a 
three year period and will result in lower operating expenses, as compared to the prior plan over 
the next three years. 

  We entered into a deferred compensation agreement with one of our senior executives resulting 

in the recognition of a $1.1 million expense during the fourth quarter. 

Agency-related expenses 

We operate several fee-based agencies and provide benefit management services on a limited basis. 
Their business activities generate commission and service fee revenues which are reported as a part of other 
income. We have excluded the direct expenses of these entities from our underwriting expense ratio 
computations because their activities and business operations are not associated with the generation of premium 
revenues. During the latter part of 2010 we discontinued certain agency activities which reduced 2010 expenses 
as compared to 2009.

Interest Expense 

The 2010 decrease in interest expense reflects a decline in average rates on our variable debt of 
approximately 50 basis points against an increase in average outstanding debt principal of approximately $1.4 
million during 2010 as compared to 2009.

Taxes 

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

(1)  We have invested in tax credit partnerships during 2010 (see Capital and Liquidity -Investment 

Exposures and Equity in Earnings (Loss) of Unconsolidated Subsidiaries). In 2010 we have recognized 
an expected tax benefit of approximately $1.0 million related to the credits to be transferred to us by the 
partnerships. 

(2)  During 2010 we reversed a valuation allowance previously established against deferred tax assets that 

were capital in character. We determined that it has become more likely than not that sufficient sources 
of taxable capital income will be available in future periods to allow us to fully utilize the deferred tax 
assets. 

(3)  We recognized additional tax of $1.3 million on the redemption of a portion of our BOLI investment as 
discussed in Capital and Liquidity -Investment Exposures. Increases in the cash surrender value on 
BOLI policies are not taxable unless redeemed. Upon redemption, the difference in the proceeds from 
redemption and premiums previously paid on the policies redeemed become taxable. In this instance, 
the difference approximated $2.9 million.

Although our effective tax rate is consistent between 2010 and 2009, current tax expense increased by 

approximately $35.4 million in 2010. In 2009 we received a current tax benefit from the sale of impaired 
securities that was $15.9 million greater than the benefit received in 2010. Additionally, in 2009 we received a 
benefit of $7.8 million related to the settlement of the CHW Judgment. 

Overview of Results–Years Ended December 31, 2009 and 2008 

Net income totaled $222.0 million for the year ended December 31, 2009 as compared to $177.7 million 

for the year ended December 31, 2008. Net income per diluted share was $6.70 and $5.22 for the years ended 
December 31, 2009 and 2008, respectively. The increase in diluted earnings per share is primarily attributable to 
an increase in net income, but also reflects a decrease in diluted weighted average shares outstanding. 

Results from the years ended December 31, 2009 and 2008, respectively, compare as follows: 

Premiums—Exclusive of PICA 

Net premiums earned declined in 2009 by approximately $32.0 million (7.0%) for the year. The decline 

reflects the effects of a competitive market place and rate reductions resulting from improved loss trends. 

Premiums—PICA 

PICA contributed net premiums earned of $70.3 million during 2009. 

Net Investment Income; Net Realized Investment Gains (Losses)—Consolidated 

Our 2009 net investment results (which include both net investment income and earnings from 
unconsolidated subsidiaries) increased by $2.0 million (1.3%) and reflect improved results from our investments 
in unconsolidated subsidiaries offset by the decline in net investment income primarily due to lower yields on 
short-term securities.  

Net realized gains were $12.8 million in 2009 as compared to net realized losses of $50.9 million for 

2008. The improvement is principally the result of a $39.0 million reduction in impairment losses due to more 
favorable market conditions during 2009. 

Gain/Loss on Extinguishment of Debt—Consolidated 

Our 2009 results reflect a $2.8 million ($1.8 million after tax) loss related to the extinguishment of debt, 

while our 2008 results reflect a $4.6 million ($2.9 million after tax) gain from the extinguishment of debt. 
During 2009 we redeemed at par surplus notes acquired in the PICA acquisition which were valued below par 
on the date of acquisition. For additional information regarding the extinguishment of debt see Note 10 to the 
Consolidated Financial Statements. 

Expenses—Exclusive of PICA 

Current accident year net losses decreased by $22.2 million (5.6%) in 2010, principally due to a decline 

in insured risks. We recognized favorable development in 2009 of $207.3 million (a $22.0 million increase).

62 

 
 
 
 
 
 
 
 
 
 
 
 
Underwriting, policy acquisition and operating expenses increased during 2009 by $1.5 million 

(1.5%) as compared to 2008, primarily due to additional expenses associated with an increase in non-
physician premiums and higher commission costs for physician premiums.  

Interest expense declined by $4.9 million in 2009 because we reduced the outstanding principal 

balance of our long-term debt during the latter half of 2008 by $129 million.

Ratios  

Our net loss ratio exclusive of PICA decreased to 39.2% in 2009 from 46.1% in 2008, primarily 

because favorable prior year loss development had a more pronounced effect on the calendar year net loss 
ratio in 2009 (because 2009 earned premium was less than 2008 earned premium, and because favorable 
loss development was higher in 2009). Our 2009 calendar year net loss ratio when PICA subsidiaries are 
included is 46.4%. 

Our expense ratio exclusive of PICA increased to 23.2% in 2009 from 21.6% in 2008, primarily 

because premiums earned decreased but expenses remained relatively flat. Our 2009 expense ratio is 
22.7% when the PICA subsidiaries are included.  

Our operating ratio exclusive of PICA decreased to 28.5% in 2009 from 33.3% in 2008, reflecting 

the improvement in the net loss ratio, offset by a higher expense ratio and lower investment ratio. Our 
operating ratio including PICA is 38.8% for 2009.  

Return on equity, which is computed only on a consolidated basis, is 14.2% for 2009. 

Non-GAAP Financial Measures 

Operating income is a Non-GAAP financial measure that is widely used to evaluate the 
performance of insurance entities. Operating income excludes the after-tax effects of realized gains or 
losses, guaranty fund assessments and debt retirement gain or loss. 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.

PRA Exclusive of PICA 

Changes in our premium volume are driven by three primary factors: our retention of existing 

business, the amount of new business we are able to generate (including business that comes to PRA as a 
result of acquisitions), and the premium charged for business that is renewed, which is affected both by 
rates charged and by the amount and type of coverage an insured chooses to purchase. The professional 
liability market continues to remain competitive with some competitors choosing to compete primarily on 
price. 

Physician premiums continue to be our primary revenue source and comprise 80% and 83% of 

our gross premiums written in 2009 and 2008, respectively. Our physician retention rate is 89% and 88% 
for the years ended December 31, 2009 and 2008, respectively. Retention rates are affected by a number 
of factors. Insureds may terminate coverage because they are leaving the practice of medicine through 
death, disability or retirement. Also, based on our underwriting evaluation, we may choose not to renew 
an insured. We may lose business to competitors or to self-insurance mechanisms (often when physicians 
join hospital based practice groups) due to pricing or other issues. 

New business increased during 2009. We wrote approximately $22 million of new physician 

business during the year that was not attributable to acquisitions, as compared to $12 million in 2008.  

In the third and fourth quarters of 2008, we began renewing physician policies for a two-year 
term in a selected jurisdiction. Written premium for the entire two-year policy term is recorded in the 
period the policy is renewed, while earned premium is recorded on a pro rata basis over the two-year 
policy term. The gross written premiums attributable to two-year policies for 2009 is $23.0 million as 
compared to $2.7 million written in 2008. Also, in 2009, in order to more evenly distribute renewals 
throughout the year, we offered early renewal to a number of insureds who would otherwise have had a 
first quarter 2010 renewal date. As a result of the shift in renewal dates, in 2010 there will be 
approximately $9 million less in business eligible to be renewed. 

As favorable loss trends have emerged we have lowered our rates where indicated. For our 

physician business, our charged rates on 2009 renewals decreased 4% on average, as compared to an 
average decrease of 6% for 2008. Our charged rates include the effects of filed rates, surcharges and 
discounts. Despite competitive pressures, we remain committed to a rate structure that will allow us to 
fulfill our obligations to our insureds, while generating competitive returns for our stockholders. 

Our non-physician healthcare providers are primarily dentists and allied health professionals. The 

2009 increase in this business is primarily attributable to business contributed by Mid-Continent. Non-
physician “other” premiums are primarily legal professional liability premiums, but also includes other 
types of general liability premiums. The acquisitions of Georgia Lawyers and Mid-Continent contributed 
additional non-physician premiums of approximately $18 million in 2009.  

We separately report tail premiums because we offer extended reporting endorsement or "tail" 

policies to insureds that are discontinuing their claims-made coverage with us, but we do not market such 
coverages separately. The amount of tail premium written and earned can vary widely from period to 
period. 

PICA 

Gross premiums written contributed by PICA consist primarily of coverages provided to 

podiatrists, who are categorized as physician premiums in the above table, and coverages provided to 
chiropractors, who are categorized as non-physician health-care providers in the above table. Our 2009 
retention rate for the core PICA business is approximately 93%.

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, beginning in late 2008 we began to renew some policies with a two-year term. 
Tail premiums are 100% earned in the period written because the policies insure only incidents that 
occurred in prior periods and are not cancellable. 

PRA Exclusive of PICA 

Exclusive of the effect of tail premiums and acquisitions, the decline in premiums earned for the 
year ended December 31, 2009 as compared to 2008 reflects declines in gross premiums written during 
2008 and 2009.  

PICA 

PICA subsidiaries contributed earned premiums of approximately $73 million during 2009; 

approximately $41.6 million of which relates to premiums written prior to the date of acquisition (and 
thus never reported in our written premiums). At December 31, 2009 approximately $1.7 million of 
premium written prior to the acquisition is yet to be earned and will be added to our earned premium on a 
pro rata basis, principally during the first quarter of 2010.

Premiums ceded represent the portion of earned premiums that we pay our reinsurers for their 

assumption of a portion of our losses. The premium that we cede to our reinsurers is determined, in part, 
by the loss experience (subject to minimums and maximums) of the business ceded to them. It takes a 
number of years before all losses are known, and in the intervening period, premiums due to the 
reinsurers are estimated.

The increase in our reinsurance expense ratio for 2009 is due to an increase in premiums ceded, 

along with a decrease in premiums earned, which reflects shifts in the mix of our premiums.  The increase 
in premiums ceded is principally related to legal professional liability premiums, which are generally 
more heavily reinsured than our physician premiums. The decline in premiums earned is principally 
attributable to physician policies with lower coverage limits for which we retain all of the risk of loss; 
consequently, there is no corresponding decrease to premiums ceded. 

The amount of reinsurance premiums incurred for prior accident years is largely determined 

based on the losses expected to be recovered, subject to certain minimums and maximums specific to the 
reinsurance agreement being adjusted. In both 2009 and 2008, we reduced our estimates of prior accident 
year gross losses within our reinsured layers of coverage, as well as the related reinsurance recoveries and 
premiums ceded. However, the reductions were more pronounced in 2009. 

PICA 

The PICA subsidiaries cede only a small portion of the risk on the policies they issue. 

Accordingly, the reinsurance expense ratio for these entities is minimal.

Fixed Maturities. The increase in income in 2009 reflects higher average invested balances, the benefit of 
which was offset almost entirely by lower yields. The increase in average invested balances is principally 
attributable to the PICA acquisition. Yields declined in 2009 as a result of proceeds from maturities and 
sales being reinvested at lower rates. Lower returns from TIPS (Treasury Inflation Protected Securities) 
also reduced yields in 2009. We expect average yields to continue to decrease in 2010, unless market 
rates improve. Average yields for our available-for-sale fixed maturity securities during 2009 and 2008 
are as follows:

Short-term Investments. The decrease in earnings from short-term investments during 2009 reflects a 
decline in market interest rates (an average of 200 basis points for the year) on lower average balances in 
2009 as compared to 2008. In the latter portion of 2008, we increased our short-term holdings because of 
the instability in the longer term market and to also provide funds needed for the PICA acquisition. As 
markets stabilized in 2009, we reduced our short-term holdings.

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 occurrence policies the insured event becomes a liability when the event takes place; for 
claims-made policies, which represent the majority of the Company's business, the insured event 
generally becomes a liability when the event is first reported to the insurer. We believe that measuring 
losses on an accident year basis is the most indicative measure of the underlying profitability of the 
premiums earned in that period since it associates policy premiums earned with the estimate of the losses 
incurred related to those policy premiums. All losses associated with the subsidiaries we acquired from 
PICA are considered current accident year losses because the insured event became a ProAssurance 
liability in 2009. 

The following table summarizes calendar year net losses and net loss ratios for the years ended 

December 31, 2009 and 2008, respectively, by separating losses between the current accident year and all 
prior accident years.

PRA Exclusive of PICA 

The current accident year loss ratio increased 1.3 points when compared to the prior year, 

approximately 60% of this increase is attributable to an increase to our reserve for the death, disability 
and retirement (DDR) provision in our claims-made polices. After a number of coverage years, most of 
our insureds qualify for this extended coverage when the insured retires or should the insured die or 
become disabled during the policy term. Our strong retention rate has resulted in an increase in the 
number of insureds expected to become eligible to receive this extended coverage and we have recorded a 
corresponding increase to the related reserve.

During the years ended December 31, 2009 and 2008, we recognized favorable loss development 

of $207.3 million and $185.3 million, on a net basis, related to reserves established in prior years. 

The principal components of development are as follows: 

Reserve development by accident year, favorable (unfavorable): 

(In millions) 

2008 & 2007 accident years 
2006 & 2005 accident years

  $  185.3 

Substantially all of the development recognized during 2009 and 2008 relates to medical 
professional liability claims-made reserves. The favorable development for medical professional claims 
made policies in both 2009 and 2008 is based upon observation of actual claims data which indicates that 
claims severity (i.e., the expected average cost of claims) is trending below our initial expectations. Given 
both the long tailed nature of our business and the past volatility of final claim settlement values, we are 
generally cautious in giving credence to the trends that lead to the recognition of favorable net loss 
development. As we conclude that sufficient credible data with respect to these trends exists we take 
appropriate actions. In the case of the claims severity trends, we believe it is appropriate to recognize the 
impact of these trends in our actuarial evaluation of prior period loss estimates while also remaining 
attentive to the past volatility of claims severity. 

In establishing the rates for our insurance products we consider loss and loss trends over a multi-

year period. To the extent that we experience improvements in claims frequency and claims severity these 
improvements are considered in our rate making process and reflected in our established rates. We have 
reflected decreased estimates of severity in our rate making process as well as in our loss estimates for 
several years. 

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. 

PICA  

The current accident year loss ratio was adversely affected by an increase to reserves for the DDR 

provision associated with PICA claims-made policies and by unfavorable development of losses 
associated with certain other liability coverages. When the effect of these two items is excluded, PICA 
2009 net loss ratio is approximately 80%. In 2010, we plan to discontinue offering the other liability 
coverage that generated the 2009 unfavorable development.

Insurance Operation Expenses-Exclusive of PICA 

Expenses during 2009 reflect a number of cost variations, but changed little on a net basis. 

Expenses for commissions, brokerage fees, and underwriting and sales salaries and benefits were higher 
in 2009, both because we earned more non-physician premiums which carry higher expenses than 
physician premiums and because more of our physician premium was generated by external 
(commissioned) agents. Also, guaranty fund recoupments are lower in 2009 than in 2008. Partially 
offsetting these higher costs is a $1.5 million reduction in share based compensation costs, due to a 
different type of award made in 2009. Costs were also reduced in 2009 by a $1.8 million benefit related to 
final settlement of the CHW Judgment (actual costs incurred were less than amounts previously 
estimated). 

Other Expense Information 

Agency-related expenses. We operate several insurance agencies and provide benefit management 
services on a limited basis through a separate PICA subsidiary. These activities generate commission and 
service fee revenues, which are reported as a part of other income. The acquisition of Mid-Continent and 
PICA increased these expenses in 2009. We have excluded the direct expenses of these activities from our 
underwriting expense ratio computations because the activities are not associated with the generation of 
premium revenues. 

Guaranty fund assessments. Insurance operation expenses in the table above are reduced by net 
recoupments from guaranty fund assessments of approximately $0.5 million and $1.3 million during 2009 
and 2008, respectively. 

Underwriting Expense Ratio-Exclusive of PICA 

The 1.6 point increase in our underwriting expense ratio is primarily a result of a 7% decline in 

net premiums earned in 2009 as compared to 2008, while expenses remained relatively flat. A non-
recurring expense reduction related to final settlement of the CHW litigation, as discussed above, reduced 
our 2009 expenses; excluding this non-recurring item increases the 2009 ratio to 23.6%. 

Underwriting Expense Ratio-PICA 

PICA 2009 expenses include non-recurring transaction related expenses of approximately $2.5 

million recorded during 2009. Excluding this non-recurring item decreases the PICA expense ratio to

15.9%. Almost 60% of PICA 2009 earned premium relates to policies written prior to the acquisition. In 
accordance with the GAAP guidance for business combinations, we did not recognize any acquisition 
expense for these policies. However, in 2010, almost all of our PICA earned premium will relate to 
policies written after the acquisition. On average, in 2010 we would expect the PICA expense ratio to 
approximate 22%. 

Interest Expense 

Consolidated 

Interest expense decreased in 2009 as compared to 2008 primarily because we reduced 
outstanding debt in the latter half of 2008. We converted all our Convertible Debentures in July of 2008 
(aggregate principal of $107.6 million) and extinguished approximately $23 million of our 2034 Trust 
Preferred Securities/Debentures (TPS/Debentures) in mid-December 2008. Also, rates on our variable 
rate debt decreased by approximately 200 basis points in 2009 as compared to 2008. These reductions in 
interest expense were partially offset by additional interest expense incurred in the latter half of 2009 
related to debt and other liabilities assumed in the PICA acquisition (see Notes 3 and 10). 

Interest expense by debt obligation is provided in the following table:

Taxes 

Consolidated 

Our effective tax rate for each period is significantly lower than the 35% statutory rate because a 
considerable portion of our net investment income is tax-exempt. The effect of tax-exempt income on our 
effective tax rate is shown in the table below: 

Statutory rate

2009 
35.0% 
(5.2%) 
0.5% 
30.3% 

Tax exempt income had a less significant effect on our 2009 effective tax rate primarily because 

2009 taxable income increased at a greater rate than tax-exempt income. Our 2009 taxable income 
reflected impairment losses of $8.0 million, whereas 2008 taxable income reflected impairment losses of 
$47.0 million. Also, we recognized more (a $22.0 million increase) favorable loss development in 2009 
than in 2008 which also increased 2009 taxable income. 

We expect to be able to realize the full benefit of deferred tax assets associated with impairment 
losses because capital gains recognized during the statutory carryback period are sufficient to absorb the

established related to PICA capital loss carry-forwards.

ITEM  7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK. 

We believe that we are principally exposed to three types of market risk related to our investment 

operations. These risks are interest rate risk, credit risk and equity price risk. 

Interest Rate Risk 

Our fixed maturities portfolio is exposed to interest rate risk. Fluctuations in interest rates have a 

direct impact on the market valuation of these securities. As interest rates rise, market values of fixed 
income portfolios fall and vice versa. Certain of the securities are held in an unrealized loss position; we 
do not intend to sell and believe we will not be required to sell any of the debt securities held in an 
unrealized loss position before its anticipated recovery. 

The following table summarizes estimated changes in the fair value of our available-for-sale fixed 
maturity securities for specific hypothetical changes in interest rates by asset class at December 31, 2010. 
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.

Interest Rate Risk (continued) 

Computations of prospective effects of hypothetical interest rate changes are based on numerous 

assumptions, including the maintenance of the existing level and composition of fixed income security 
assets, and should not be relied on as indicative of future results. 

Certain shortcomings are inherent in the method of analysis presented in the computation of the 

fair value of fixed rate instruments. Actual values may differ from those projections presented should 
market conditions vary from assumptions used in the calculation of the fair value of individual securities, 
including non-parallel shifts in the term structure of interest rates and changing individual issuer credit 
spreads. 

ProAssurance's cash and short-term investment portfolio at December 31, 2010 is 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 and due to the 

amounts due from our reinsurers. We control this exposure by emphasizing investment grade credit 
quality in the fixed income securities we purchase and by monitoring the credit standing of our reinsurers. 

As of December 31, 2010, 97% of our fixed maturity securities are rated investment grade as 
determined by Nationally Recognized Statistical Rating Organizations (NRSROs), such as A.M. Best, 
Fitch, Moody's, and Standard & Poor's. We believe that this concentration in investment grade securities 
reduces our exposure to credit risk on our fixed income investments to an acceptable level. However, 
investment grade securities, in spite of their rating, can rapidly deteriorate and result in significant losses. 
Ratings published by the NRSROs are one of the tools used to evaluate the credit worthiness of our 
securities. The ratings reflect the subjective opinion of the rating agencies as to the credit worthiness of 
the securities, and therefore, we may be subject to additional credit exposure should the rating prove to be 
unreliable.  

We hold $1.2 billion of municipal bonds. These bonds may have enhanced credit ratings as a 

result of guarantees by an insurer, but we require the bonds that we purchase to meet our credit criteria on 
a stand-alone basis. As of December 31, 2010, on a stand-alone basis, our municipal bonds have a 
weighted average rating of AA. 

Our receivable from reinsurers on paid and unpaid losses at December 31, 2010 is $282 million. 
A detail listing of individual reinsurance balances of greater than $10 million and the current credit rating 
of that reinsurer is provided in capital and liquidity under the sub-header “Reinsurance.” 

Equity Price Risk 

At December 31, 2010 the fair value of our investment in common stocks was $40.8 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 is 1.00. 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 10% to $44.9 million. Conversely, a 10% 
decrease in the S&P 500 Index would imply a decrease of 10% in the fair value of these securities to 
$36.7 million. The selected hypothetical changes of plus or minus 10% do not reflect what could be 
considered the best or worst case scenarios and are used for illustrative purposes only.

ITEM 9A. CONTROLS AND PROCEDURES. 

Disclosure Controls 

Under the supervision and with the participation of management, including the Chief Executive 

Officer and Chief Financial Officer, the Company has evaluated the effectiveness of the design and 
operation of our disclosure controls and procedures as of the end of the fiscal year ended December 31, 
2010. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded 
that these controls and procedures are effective. 

Disclosure controls and procedures are defined in Exchange Act Rule 13a-15(e) and include the 

Company's controls and other procedures that are designed to ensure that information, required to be 
disclosed by the Company in the reports that it files or submits under the Exchange Act, is accumulated 
and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as 
appropriate, to allow timely decisions regarding required disclosure. 

Management's Report on Internal Control over Financial Reporting 

Our management is responsible for establishing and maintaining adequate internal control over 

financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the 
supervision and with the participation of our management, including our Chief Executive Officer and 
Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over 
financial reporting as of December 31, 2010 based on the framework in Internal Control–Integrated 
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). 
Based on that evaluation, our management concluded that our internal control over financial reporting 
was effective as of December 31, 2010 and that there was no change in the Company's internal controls 
during the fiscal year then ended that has materially affected, or is reasonably likely to materially affect, 
the Company's internal control over financial reporting, other than as described below. 

Our management excluded APS’s systems and processes from the scope of our assessment of 

internal control over financial reporting as of December 31, 2010 in reliance on the guidance set forth in 
Question 3 of a “Frequently Asked Questions” interpretive release issued by the staff of the Securities and 
Exchange Commission’s Office of the Chief Accountant and the Division of Corporation Finance in June 
2004 (and revised on October 6, 2004). We are excluding APS from that scope because we expect 
substantially all of its significant systems and processes to be converted to those of ProAssurance during 
2011. At December 31, 2010 APS represented $324.2 million or 6.6% of total assets, and $6.2 million or 
0.9% of total revenues for the year then ended. 

Ernst & Young LLP, an independent registered public accounting firm, has audited the 
effectiveness of our internal controls over financial reporting as of December 31, 2010 as stated in their 
report which is included elsewhere herein.

The Board of Directors and Stockholders of ProAssurance Corporation  

Report of Independent Registered Public Accounting Firm 

We have audited ProAssurance Corporation and subsidiaries’ internal control over financial reporting as 

of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by the 
Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). ProAssurance 
Corporation and subsidiaries’ management is responsible for maintaining effective internal control over 
financial reporting, and for its assessment of the effectiveness of internal control over financial reporting 
included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our 
responsibility is to express an opinion on the company’s internal control over financial reporting based on our 
audit. 

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight 

Board (United States). Those standards require that we plan and perform the audit to obtain reasonable 
assurance about whether effective internal control over financial reporting was maintained in all material 
respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing 
the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal 
control based on the assessed risk, and performing such other procedures as we considered necessary in the 
circumstances. We believe that our audit provides a reasonable basis for our opinion. 

A company’s internal control over financial reporting is a process designed to provide reasonable 

assurance regarding the reliability of financial reporting and the preparation of financial statements for external 
purposes in accordance with generally accepted accounting principles. A company’s internal control over 
financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in 
reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial 
statements in accordance with generally accepted accounting principles, and that receipts and expenditures of 
the company are being made only in accordance with authorizations of management and directors of the 
company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized 
acquisition, use, or disposition of the company’s assets that could have a material effect on the financial 
statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect 
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that 
controls may become inadequate because of changes in conditions, or that the degree of compliance with the 
policies or procedures may deteriorate. 

As indicated in the accompanying Management’s Report on Internal Control over Financial Reporting, 
management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did 
not include the internal controls of American Physicians Services Group, which is included in the 2010 
consolidated financial statements of ProAssurance Corporation and subsidiaries and constituted 6.7% and 10.4% 
of total and net assets, respectively, as of December 31, 2010, and .9%  and .4% of revenues and net income, 
respectively, for the year then ended. Our audit of internal control over financial reporting of ProAssurance 
Corporation and subsidiaries also did not include an evaluation of the internal control over financial reporting of 
American Physicians Services Group. 

In our opinion, ProAssurance Corporation and subsidiaries maintained, in all material respects, effective 

internal control over financial reporting as of December 31, 2010, based on the COSO criteria. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight 

Board (United States), the consolidated balance sheets as of December 31, 2010 and 2009, and the related 
consolidated statements of changes in capital, income and cash flow for each of the three years in the period 
ended December 31, 2010, of ProAssurance Corporation and subsidiaries and our report dated February 23, 
2011 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm 

To the Board of Directors and Stockholders of ProAssurance Corporation 

We have audited the accompanying consolidated balance sheets of ProAssurance Corporation 

and subsidiaries as of December 31, 2010 and 2009, and the related consolidated statements of changes 
in capital, income and cash flow for each of the three years in the period ended December 31, 2010. Our 
audits also included the financial statement schedules listed in the Index at Item 15(a). These financial 
statements and schedules are the responsibility of the Company's management. Our responsibility is to 
express an opinion on these financial statements and schedules based on our audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting 
Oversight Board (United States). Those standards require that we plan and perform the audit to obtain 
reasonable assurance about whether the financial statements are free of material misstatement. An audit 
includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial 
statements. An audit also includes assessing the accounting principles used and significant estimates made 
by management, as well as evaluating the overall financial statement presentation. We believe that our 
audits provide a reasonable basis for our opinion. 

In our opinion, the financial statements referred to above present fairly, in all material respects, 
the consolidated financial position of ProAssurance Corporation and subsidiaries at December 31, 2010 
and 2009, and the consolidated results of their operations and their cash flow for each of the three years in 
the period ended December 31, 2010, in conformity with U.S. generally accepted accounting principles. 
Also, in our opinion, the related financial statement schedules, when considered in relation to the basic 
financial statements taken as a whole, present fairly in all material respects the information set forth 
therein. 

We also have audited, in accordance with the standards of the Public Company Accounting 

Oversight Board (United States), ProAssurance Corporation’s internal control over financial reporting as 
of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued 
by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated 
February 23, 2011 expressed an unqualified opinion thereon.

ProAssurance Corporation and Subsidiaries 
Notes to Consolidated Financial Statements 
December 31, 2010 

1. Accounting Policies 

Organization and Nature of Business 

ProAssurance Corporation (ProAssurance or PRA), a Delaware corporation, is an insurance 

holding company for wholly-owned specialty property and casualty insurance companies that principally 
provide professional liability insurance for providers of health care services, and to a lesser extent, 
providers of legal services and other professional services. ProAssurance operates in the United States of 
America (U.S.) in a single reportable segment. 

Principles of Consolidation 

The accompanying consolidated financial statements include the accounts of ProAssurance 
Corporation and its wholly-owned subsidiaries. Investments in entities where ProAssurance holds a 
greater than minor interest but does not hold a controlling interest are accounted for using the equity 
method. All significant intercompany accounts and transactions are eliminated in consolidation. 

Basis of Presentation 

The preparation of financial statements in conformity with GAAP requires management to make 

estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and 
expenses, and disclosures related to these amounts at the date of the financial statements. Actual results 
could differ from those estimates.   

Accounting Policies 

The significant accounting policies followed by ProAssurance in making estimates that materially 

affect financial reporting are summarized in these notes to the consolidated financial statements. 

Recognition of Revenues 

Insurance premiums are recognized as revenues pro rata over the terms of the policies, which are 

generally one year in duration. 

At December 31, 2010 ProAssurance has established allowances for credit losses related to 

premium and agency receivables as follows:

Losses and Loss Adjustment Expenses 

ProAssurance establishes its reserve for losses and loss adjustment expenses (reserve for losses) 

based on estimates of the future amounts necessary to pay claims and expenses associated with the 
investigation and settlement of claims. The reserve for losses is determined on the basis of individual 
claims and payments thereon as well as actuarially determined estimates of future losses based on past 
loss experience, available industry data and projections as to future claims frequency, severity, 
inflationary trends, judicial trends, legislative changes and settlement patterns. 

Management establishes the reserve for losses after taking into consideration a variety of factors 
including the conclusions reached by internal actuaries, premium rates, claims frequency, historical paid

and incurred loss development trends, the effect of inflation, general economic trends, the legal and 
political environment, and the reports received from external actuaries. Internal actuaries perform an in-
depth review of the reserve for losses at least semi-annually using the loss and exposure data of 
ProAssurance subsidiaries. Management engages external actuaries to review subsidiary loss and 
exposure data and provide reports to Management regarding the adequacy of reserves. 

Estimating casualty insurance reserves, and particularly liability reserves, is a complex process. 
Claims may be resolved over an extended period of time, often five years or more, and may be subject to 
litigation. Estimating losses for liability claims requires ProAssurance to make and revise judgments and 
assessments regarding multiple uncertainties over an extended period of time. As a result, reserve 
estimates may vary significantly from the eventual outcome. Reserve estimates and the assumptions on 
which these estimates are predicated are regularly reviewed and updated as new information becomes 
available. Any adjustments necessary are reflected in then current operations. Due to the size of 
ProAssurance’s reserve for losses, even a small percentage adjustment to these estimates could have a 
material effect on earnings in the period in which the adjustment is made, as is the case in 2010, 2009 and 
2008. 

The effect of adjustments made to reinsured losses is mitigated by the corresponding adjustment 

that is made to reinsurance recoveries. Thus, in any given year, ProAssurance may make significant 
adjustments to gross losses that have little effect on its net losses. 

Reinsurance Receivables 

ProAssurance enters into reinsurance agreements whereby other insurance entities agree to 
assume a portion of the risk associated with the policies issued by ProAssurance. In return, ProAssurance 
agrees to pay a premium to the reinsurer. ProAssurance purchases reinsurance to provide for greater 
diversification of business and to allow management to control exposure to potential losses arising from 
large risks.  

Receivable from Reinsurers on Paid Losses is the estimated amount of losses already paid that 

will be recoverable from reinsurers. Receivable from Reinsurers on Unpaid Losses is the estimated 
amount of future loss payments that will be recoverable from reinsurers. Reinsurance Recoveries are the 
portion of losses incurred during the period that are estimated to be allocable to reinsurers. Premiums 
ceded are the estimated premiums that will be due to reinsurers with respect to premiums earned and 
losses incurred during the period. 

These estimates are based upon management’s estimates of ultimate losses and the portion of 

those losses that are allocable to reinsurers under the terms of the related reinsurance agreements. Given 
the uncertainty of the ultimate amounts of losses, these estimates may vary significantly from the eventual 
outcome. Management regularly reviews these estimates and any adjustments necessary are reflected in 
the period in which the estimate is changed. Due to the size of the receivable from reinsurers, even a 
small adjustment to the estimates could have a material effect on ProAssurance’s results of operations for 
the period in which the change is made. 

Reinsurance contracts do not relieve ProAssurance from its obligations to policyholders. 

ProAssurance continually monitors its reinsurers to minimize its exposure to significant losses from 
reinsurer insolvencies. Any amount determined to be uncollectible is written off in the period in which the 
uncollectible amount is identified. 

Investments 

Fair Values 

Fair value is determined using an exchange traded price, if available, or market information as 

provided by independent pricing services. Fair values for securities not actively traded are estimated using 
89 

 
 
 
ProAssurance Corporation and Subsidiaries 
Notes to Consolidated Financial Statements 
December 31, 2010 

1. Accounting Policies (continued) 

exchange traded prices for similar assets, when available, or other multiple observable inputs. 
Management reviews valuations of securities obtained from the pricing services for accuracy based upon 
the specifics of the security, including class, maturity, credit rating, durations, collateral, and comparable 
markets for similar securities.

Multiple observable inputs are not available for certain of our investments, including municipal 
bonds and corporate debt not actively traded, a private annuity and interests in private investment funds. 
Management values municipal bonds and corporate debt either using a single non-binding broker quote or 
pricing models that utilize market based assumptions that have limited observable inputs. Annuities are 
valued using a discounted cash flow model. Management values interests in private investment funds 
based on the net asset value of the interest held, as provided by the fund. 

Fixed Maturities and Equity Securities 

Fixed maturities and equity securities are considered as either available-for-sale or trading 

securities. 

Available-for-sale securities are carried at fair value, as described above, and unrealized gains 
and losses on such available-for-sale securities are included, net of related tax effects, in Stockholders’ 
Equity as a component of Accumulated Other Comprehensive Income (Loss). 

Investment income includes amortization of premium and accretion of discount related to debt 
securities acquired at other than par value. Debt securities and mandatorily redeemable preferred stock 
with maturities beyond one year when purchased are classified as fixed maturities.  

Trading portfolio securities are carried at fair value, as described above, with the holding gains 

and losses included in realized investment gains and losses in the current period. 

Short-term Investments 

Short-term investments, which have a maturity at purchase of one year or less, are primarily 
comprised of investments in U.S. Treasury obligations and commercial paper. All balances are reported at 
amortized cost, which approximates fair value. 

Other Investments 

Investments in limited partnerships/liability companies where ProAssurance has virtually no 

influence over the operating and financial policies of an investee are accounted for using the cost method. 
Under the cost method, investments are valued at cost, with investment income recognized when 
received. 

Investment in Unconsolidated Subsidiaries 

Investments in limited partnerships/liability companies where ProAssurance is deemed to have 

influence because it holds a greater than minor interest are accounted for using the equity method. Under 
the equity method, the recorded basis of the investment is adjusted each period for the investor’s pro rata 
share of the investee’s income or loss. Investments in unconsolidated subsidiaries include tax credit 
partnerships accounted for using the equity method, whereby ProAssurance’s proportionate share of 
income or loss is included in investment income. Tax credits received from the partnerships are 
recognized in the period received as a reduction to current tax expenses. 

Business Owned Life Insurance (BOLI) 

ProAssurance owns life insurance contracts on certain management employees. The life insurance 

contracts are carried at their current cash surrender value. Changes in the cash surrender value are 

90 

 
 
 
ProAssurance Corporation and Subsidiaries

1. Accounting Policies (continued) 

included in income in the current period as investment income. Death proceeds from the contracts are 
recorded when the proceeds become payable under the policy terms. 

Realized Gains and Losses 

Realized investment gains and losses are recognized on the specific identification basis.  

Other-than-temporary Impairments 

ProAssurance evaluates its investment securities on at least a quarterly basis for declines in fair 

value below recorded cost basis for the purpose of determining whether these declines represent other-
than-temporary declines. The assessment of whether the amortized cost basis of debt securities, 
particularly asset-backed debt securities, is expected to be recovered requires management to make 
assumptions regarding various matters affecting cash flows to be received in the future. The choice of 
assumptions is subjective and requires the use of judgments; actual credit losses experienced in future 
periods may differ from management’s estimates of those credit losses. 

If there is intent to sell the security or if it is more likely than not that the security will be required 

to be sold before full recovery of its amortized cost basis, ProAssurance considers a decline in fair value 
to be an other-than-temporary impairment. Otherwise, ProAssurance considers the following factors in 
determining whether an investment’s decline is other-than-temporary:  

For equity securities: 

 

 

 

the length of time for which the fair value of the investment has been less than its 
recorded basis; 
the financial condition and near-term prospects of the issuer underlying the 
investment, taking into consideration the economic prospects of the issuer's industry 
and geographical region, to the extent that information is publicly available;  
the historical and implied volatility of the fair value of the security; 

For debt securities, an evaluation is made as to whether the decline in fair value is due to 
credit loss, which is defined as the excess of the current amortized cost basis of the security over 
the present value of expected future cash flows. Methodologies used to estimate the present value 
of expected cash flows to determine if a decline is due to a credit loss are: 

  For non-structured fixed maturities (U.S. Treasury securities, obligations of U.S. 
Government and government agencies and authorities, obligations of states, 
municipalities and political subdivisions, and corporate debt) the estimate of expected 
cash flows is determined by projecting a recovery value and a recovery time frame 
and assessing whether further principal and interest will be received. ProAssurance 
considers the following in projecting recovery values and recover time frames: 
 
 

third party research and credit rating reports; 
the current credit standing of the issuer, including credit rating downgrades, 
whether before or after the balance sheet date; 
internal assessments and the assessments of external portfolio managers regarding 
specific circumstances surrounding an investment, which indicate the investment is 
more or less likely to recover its amortized cost than other investments with a 
similar structure;  
failure of the issuer of the security to make scheduled interest or principal 
payments; 

 

 

  For structured securities (primarily asset-backed securities), ProAssurance estimates 

the present value of the security’s cash flows using the effective yield of the security at 

91 

 
 
 
ProAssurance Corporation and Subsidiaries 
Notes to Consolidated Financial Statements 
December 31, 2010 

1. Accounting Policies (continued) 

the date of acquisition (or the most recent implied rate used to accrete the security if the 
implied rate has changed as a result of a previous impairment or changes in expected 
cash flows). ProAssurance incorporates six month averages of the levels of 
delinquencies, defaults, severities, and prepayments in the securitization, for the 
parameters applied to the assets underlying the securitization in determining the net 
present value of the cash flows.  

Investments in private investment funds are evaluated for impairment by comparing 

ProAssurance’s carrying value to net asset value (NAV) of ProAssurance’s interest in the fund as reported 
by the fund manager. Additionally, Management considers the performance of the fund relative to the 
market, the stated objectives of the fund, and cash flows expected from the fund and fund audit reports, if 
available. 

Tax credit partnership investments are evaluated for OTTI by comparing cash flow projections of 

future operating results of the underlying projects generating the tax credits to the recorded value of the 
investment, taking into consideration ProAssurance’s ability to utilize the tax credits from the 
investments. 

ProAssurance recognizes other than temporary impairments, including impairments of debt 

securities due to credit loss, in earnings as a part of net realized investment gains (losses). In subsequent 
periods, any measurement of gain or loss or impairment is based on the revised amortized basis of the 
security. Declines in fair value, including impairments of debt securities that are not evaluated as being 
due to credit loss, not considered to be other-than-temporary are recognized in other comprehensive 
income. 

Asset-backed securities that have been impaired due to credit or are below investment grade 

quality are accounted for under the effective yield method. Under the effective yield method estimates of 
cash flows expected over the life of asset-backed securities are then used to recognize income on the 
investment balance for subsequent accounting periods. 

Cash and Cash Equivalents 

For purposes of the consolidated balance sheets and statements of cash flow, ProAssurance 

considers all demand deposits and overnight investments to be cash equivalents. 

Deferred Policy Acquisition Costs 

Costs that vary with and are directly related to the production of new and renewal premiums 
(primarily premium taxes, commissions and underwriting salaries) are deferred to the extent they are 
recoverable against unearned premiums and are amortized as related premiums are earned.  

Income Taxes/Deferred Taxes 

ProAssurance files a consolidated federal income tax return. Tax-related interest and penalties are 

recognized as components of tax expense. 

Deferred federal income taxes arise from the recognition of temporary differences between the 

basis of assets and liabilities determined for financial reporting purposes and the basis determined for 
income tax purposes. ProAssurance’s temporary differences principally relate to loss reserves, unearned 
premium, deferred policy acquisition costs, unrealized investment gains (losses), investment impairments 
and intangibles.  Deferred tax assets and liabilities are measured using the enacted tax rates expected to be 
in effect when such benefits are realized. ProAssurance reviews its deferred tax assets quarterly for 
impairment. If management determines that it is more likely than not that some or all of a deferred tax

1. Accounting Policies (continued) 

asset will not be realized, a valuation allowance is recorded to reduce the carrying value of the asset. In 
assessing the need for a valuation allowance, management is required to make certain judgments and 
assumptions about the future operations of ProAssurance based on historical experience and information 
as of the measurement period regarding reversal of existing temporary differences, carryback capacity, 
future taxable income, including its capital and operating characteristics, and tax planning strategies. 

Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the 

future. Management is not aware of any such changes that would have a material effect on the Company’s 
results of operations, cash flows or financial position.  

Real Estate 

Real Estate balances are reported at cost or, for properties acquired in business combinations, 

estimated fair value on the date of acquisition, less accumulated depreciation. Real estate consists of 
properties primarily in use as corporate offices, but also includes land and a building held for sale. 
Properties held for sale have a combined carrying value of approximately $4.2 million. Depreciation is 
computed over the estimated useful lives of the related property using the straight-line method. Excess 
office capacity is leased or made available for lease; rental income is included in other income and real 
estate expenses are included in underwriting, policy acquisition and operating expenses.  

Real estate accumulated depreciation is approximately $17.2 million and $15.9 million at 

December 31, 2010 and 2009, respectively. Real estate depreciation expense for the three years ended 
December 31, 2010, 2009 and 2008 is $1.4 million, $1.2 million and $1.0 million, respectively. 

Amortizable Intangible Assets 

Intangible assets with definite lives are amortized over the estimated useful life of the asset. 

Intangible assets with an indefinite life are not amortized. Intangible assets are evaluated for impairment 
on an annual basis. Accumulated amortization of intangible assets is $11.2 million and $10.9 million at 
December 31, 2010 and 2009. 

Goodwill 

ProAssurance makes at least an annual assessment as to whether the value of its goodwill assets 

are impaired. Management evaluates the carrying value of goodwill annually during the fourth quarter 
and before the annual evaluation if events occur or circumstances change that would more likely than not 
reduce the fair value below the carrying value. Because ProAssurance operates in a single operating 
segment and all components within the segment are economically similar, ProAssurance is considered a 
single reporting unit for the purposes of the impairment evaluation. In assessing goodwill, Management 
estimates the fair value of the reporting unit on the evaluation date based on the Company’s market 
capitalization and an expected premium that would be paid to acquire control of the Company (a control 
premium) and performs a sensitivity analysis using a range of historical stock prices and control 
premiums. Management concluded in 2010, 2009, and 2008 that the fair value of the Company’s 
reporting unit exceeded the carrying value and no adjustment to impair goodwill was necessary. 

Goodwill approximated $161.5 million at December 31, 2010 and $122.3 million at December 

31, 2009. The increase during 2010 is entirely attributable to acquisitions as described in Note 2.

1. Accounting Policies (continued) 

Treasury Stock 

Treasury shares are reported at cost, and are reflected on the balance sheets as an unallocated 

reduction of total equity. 

Share-Based Payments 

ProAssurance recognizes compensation cost for share-based payments (including stock options, 

performance shares and restricted share units) using the modified prospective method whereby the 
methodology for recognizing compensation expense differs depending upon the grant date of each share-
based payment award. Compensation cost for awards granted after January 1, 2006 is recognized based 
on the grant-date fair value of the award over the relevant service period of the award; for awards that 
vest in increments (graded vesting), compensation cost is recognized over the relevant service period for 
each separately vested portion of the award. Compensation cost for awards granted prior to January 1, 
2006 but not vested on January 1, 2006 is recognized over the remaining service period related to those 
awards, using the same calculation methodologies, including grant-date fair values, as was used to 
prepare pro forma disclosures prior to January 1, 2006. Excess tax benefits (tax deductions realized in 
excess of the compensation costs recognized for the exercise of the awards, multiplied by the incremental 
tax rate) are reported as financing cash inflows. 

Subsequent Events 

In connection with its preparation of the Consolidated Financial Statements, ProAssurance has 

evaluated events that occurred subsequent to December 31, 2010, for recognition or disclosure in its 
financial statements and notes to the financial statements. 

Accounting Changes Adopted 

Subsequent Events 

In February 2010 the FASB issued amended guidance on disclosure of subsequent events that 

was effective immediately. The guidance eliminates the requirement for an SEC filer to disclose the date 
through which it has evaluated subsequent events. Adoption had no effect on ProAssurance’s results of 
operations or financial position. 

Fair Value Measurements 

Effective for interim and annual reporting periods beginning after December 15, 2009 or 
December 15, 2010, as specified, the FASB revised GAAP guidance related to fair value measurement to 
require additional disclosures and to clarify certain existing disclosure requirements. The guidance is 
intended to improve the disclosures and increase transparency in financial reporting. ProAssurance 
adopted the revised guidance on January 1, 2010 except for disclosures about purchases, sales, issuances, 
and settlements in the roll forward of activity in Level 3 fair value measurements which are effective for 
interim and annual reporting periods beginning on or after December 15, 2010; adoption had no effect on 
ProAssurance’s results of operations or financial position. 

Own-Share Lending Arrangements in Contemplation of Convertible Debt Issuance 

Effective for interim and annual reporting periods beginning on or after December 15, 2009 for 

outstanding arrangements and effective otherwise for reporting periods beginning on or after June 15, 
2009, the FASB issued guidance related to share-lending arrangements for an entity’s own shares 
executed in contemplation of a convertible debt offering or other financing. ProAssurance adopted the 
guidance on January 1, 2010; adoption had no effect on ProAssurance’s results of operations or financial 
position.

1. Accounting Policies (continued) 

Consolidation of Variable Interest Entities 

Effective at the start of a reporting entity’s first fiscal year beginning after November 15, 2009, 

the FASB revised guidance which changes how a reporting entity determines whether or not to 
consolidate its interest in an entity that is insufficiently capitalized or is not controlled through voting (or 
similar) rights. The determination of whether a reporting entity is required to consolidate another entity is 
now based on, among other things, the other entity’s purpose and design and the reporting entity’s ability 
to direct the activities of the other entity that most significantly impact the other entity’s economic 
performance. The revised guidance also requires the reporting entity to provide additional disclosures 
about its involvement with variable interest entities and any significant changes in risk exposure due to 
that involvement. A reporting entity will be required to disclose how its involvement with a variable 
interest entity affects the reporting entity’s financial statements. ProAssurance adopted the revised 
guidance on January 1, 2010; adoption had no material effect on ProAssurance’s results of operations or 
financial position. 

Transfers and Servicing-Accounting for Transfers of Financial Assets 

Effective at the start of a reporting entity’s first fiscal year beginning after November 15, 2009, 

the FASB revised guidance that requires additional disclosure regarding transfers of financial assets, 
including securitization transactions, where entities have continuing exposure to risks related to the 
transferred financial assets. ProAssurance adopted the revised guidance on January 1, 2010; adoption had 
no effect on ProAssurance’s results of operations or financial position. 

Investments—Disclosure Requirements; Other-than-temporary Impairments 

Effective for interim and annual reporting periods ending on or after June 15, 2009, the FASB 

revised GAAP to require expanded disclosures related to investments in debt and equity securities. 
Guidance regarding other-than-temporary impairments was also revised. Previous investment guidance 
required that an impairment of a debt security be considered as other-than-temporary unless management 
could assert both the intent and the ability to hold the impaired security until recovery of value. The 
revised impairment guidance specifies that an impairment be considered as other-than-temporary unless 
an entity can assert that it has no intent to sell the security and that it is not more likely than not that the 
entity will be required to sell the security before recovery of its anticipated amortized cost basis.  

The guidance establishes the concept of credit loss. Credit loss is defined as the difference 

between the present value of the cash flows expected to be collected from a debt security and the 
amortized cost basis of the security. The new guidance states that “…in instances in which a 
determination is made that a credit loss exists but the entity does not intend to sell the debt security and it 
is not more likely than not that the entity will be required to sell the debt security before the anticipated 
recovery of its remaining amortized cost basis” an impairment is to be separated into (a) the amount of the 
total impairment related to the credit loss and (b) the amount of total impairment related to all other 
factors. The credit loss component of the impairment is to be recognized in income of the current period. 
The non-credit component is to be recognized as a part of other comprehensive income (OCI). Transition 
provisions require a cumulative effect adjustment to reclassify the noncredit component of a previously 
recognized other-than-temporary impairment from retained earnings to accumulated other comprehensive 
income “…if an entity does not intend to sell and it is not more likely than not that the entity will be 
required to sell the security before recovery of its amortized cost basis.” We adopted the revised guidance 
on the date it became effective, which for ProAssurance was April 1, 2009. On the date of adoption our 
debt securities included non-credit impairment losses previously recognized in earnings of approximately 
$5.4 million. In accordance with the transition provisions of the revised guidance, we reclassified these

95 

 
 
 
ProAssurance Corporation and Subsidiaries 
Notes to Consolidated Financial Statements 
December 31, 2010 

1. Accounting Policies (continued) 

non-credit losses, net of tax, from retained earnings to accumulated other comprehensive income as of 
April 1, 2009, the date of adoption (a $3.5 million increase to retained earnings; a $3.5 million decrease to 
accumulated other comprehensive income). 

Business Combinations 

Effective prospectively for business combinations for which the acquisition date is on or after the 
beginning of the first annual reporting period beginning on or after December 15, 2010, the FASB issued 
guidance related to pro forma disclosure information for business combinations. The guidance clarifies 
that the required pro forma revenue and earnings disclosures should be prepared as if the business 
combination had occurred at the beginning of the prior annual reporting period. The guidance also 
expands supplemental pro forma disclosures to include a description of the nature and amount of material, 
nonrecurring pro forma adjustments included in the reported pro forma revenue and earnings. Early 
adoption is permitted and ProAssurance has adopted the guidance as of December 31, 2010 and has 
prepared its pro forma business combination disclosures in accordance with the guidance. 

Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses 

During 2010 the FASB issued new guidance, effective for interim or annual reporting periods 

beginning on or after December 15, 2010, that requires entities to disclose detailed information regarding 
the credit quality of financing receivables, including credit risk exposures and the allowance for credit 
losses. ProAssurance has adopted the guidance effective for the annual reporting period ended December 
31, 2010. 

Accounting Changes Not Yet Adopted 

Intangibles-Goodwill and Other 

Effective for interim and annual reporting periods beginning after December 15, 2010, the FASB 

revised guidance related to goodwill impairment testing. The revised guidance clarifies that when 
evaluating goodwill associated with a reporting unit that has a zero or negative carrying value,  an initial 
determination should be made as to whether it is more likely than not that the goodwill is impaired. When 
impairment is more likely than not, the goodwill is required to be tested for impairment. Adoption of this 
guidance is not expected to have a material effect on our results of operations or financial position.  

Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts 

Effective for fiscal years beginning after December 15, 2011, the FASB revised guidance 
regarding the interpretation of which costs relating to the acquisition of new or renewal insurance 
contracts qualify for deferral. The guidance permits deferral of qualifying costs associated only with 
successful contract acquisitions. The portion of internal selling agent and underwriter salary and benefit 
costs allocated to unsuccessful contracts, as well as advertising costs, are excluded. The guidance should 
be applied prospectively, but may be applied retrospectively for all prior periods. Adoption of this 
guidance is not expected to have a material effect on our results of operations or financial position. 

2. Acquisitions  

All entities acquired in 2010 and 2009 have been accounted for in accordance with GAAP 
relating to business combinations and are considered to be a part of ProAssurance’s sole reporting 
segment, the professional liability segment. No entities were acquired in 2008.

2. Acquisitions (continued)  

On November 30, 2010 ProAssurance acquired 100% of the outstanding shares of American 

Physicians Service Group, Inc. (APS) as a means of expanding its professional liability business. Total 
purchase consideration transferred had a fair value of $237 million on the acquisition date, November 30, 
2010 and included cash of $233 million and deferred compensation commitments of $4 million. 
ProAssurance incurred expenses related to the purchase of approximately $2 million during 2010, 
primarily in the third and fourth quarters. These expenses have been included as a part of operating 
expenses in the periods incurred. 

On April 1, 2009 ProAssurance acquired Podiatry Insurance Company of America and 

subsidiaries (PICA) through a cash sponsored demutualization as a means of expanding its 
professional liability insurance operations. One PICA subsidiary, PACO Assurance Company, Inc. 
(PACO), is now wholly owned by a ProAssurance intermediate holding company rather than by 
PICA. ProAssurance purchased all of PICA’s outstanding stock created in the demutualization for 
$120 million in cash and $15 million in premium credits to eligible policyholders to be redeemed 
over a three year period beginning in 2010. Total purchase consideration transferred had a fair value 
of $133.8 million on the acquisition date, April 1, 2009. ProAssurance incurred expenses related to 
the purchase of approximately $2.5 million during 2009, primarily in the second quarter, and $0.7 
million during 2008, primarily in the fourth quarter. These expenses have been included as a part of 
operating expenses in the periods incurred. 

The purchase consideration for each acquisition was allocated to the assets acquired and 
liabilities assumed based on their estimated fair values on the acquisition dates, as detailed in the 
schedule below. Goodwill of $39.1 million for the APS acquisition and $36.7 million for the PICA 
acquisition was recognized equal to the excess of the purchase price over the net fair value of the 
identifiable assets acquired and liabilities assumed. None of the goodwill is expected to be tax 
deductible.

ProAssurance believes that all contractual cash flows related to acquired receivables will be 

collected. The fair value of net assets acquired includes fair value adjustments to record real estate 
assets at appraised market values. The fair value of long-term debt and a related interest rate swap

based on Management’s assessment of the expected outcomes of pending litigation and a reasonable 
estimate of losses expected to be incurred. 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 profit margin and a risk premium, and were 
determined to be materially the same as the recorded cost basis acquired.

The final purchase price allocation of APS is subject to the completion of the valuation of certain 

assets and liabilities and will be finalized within one year of the transaction date or sooner. Specifically, 
Management’s review of APS reserves for losses and loss adjustment expenses and related reinsurance 
recoverables and deferred tax assets is on-going and is subject to adjustments within the one year 
measurement period. 

The following table discloses the amount of APS revenues and earnings, from the acquisition on 
November 30, 2010, that are included in ProAssurance consolidated results for the year ended December 
31, 2010. The table also includes supplemental pro forma information reflecting the combined results of

Pro forma combined results shown above have been adjusted, net of related tax effects, to reflect 
the following: 1) for APS, workforce reductions as if the reductions had occurred January 1, 2009, 2) the 
exclusion of transaction costs, 3) the reversal of the effect of writing off policy acquisition costs as of the 
acquisition date, 4) the amortization of intangibles recorded as a result of the purchase price allocation 
and 5) the amortization of the investment purchase adjustments. 

During 2009, ProAssurance also completed acquisitions of a general agency and an insurance 

company focused on legal professional liability coverages. Neither acquisition was material, individually 
or in the aggregate. Assets acquired and liabilities assumed were recorded based on estimated fair values

as of the dates of the acquisitions. The excess of the purchase price over the fair values of the identifiable 
net assets acquired was recognized as goodwill totaling $13.4 million for the two acquisitions, 
approximately $12.3 million of which is expected to be tax deductible. Consideration for these 
acquisitions included 100,533 ProAssurance common shares, which were reissued from treasury stock. 
The shares, which had a cost basis of approximately $5.0 million, were valued at $5.2 million, based on 
the market value of ProAssurance common shares on the date of closing.

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/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. 

The following tables present information about ProAssurance's assets and liabilities that are 

measured at fair value on a recurring basis as of December 31, 2010 and December 31, 2009 and indicate 
the fair value hierarchy of the valuation techniques utilized to determine such value. 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. ProAssurance's assessment of the significance of a particular input to the fair value 
measurement requires judgment and considers factors specific to the assets being valued.

(1)  Short-term investments are reported at amortized cost, which approximates fair value. 
(2)  Includes interests in private investment funds that are valued at the net asset value provided by the fund, which approximates fair value. 

Other equity interests for which the carrying value of the interest does not approximate fair value are excluded.

carried at cost are excluded. 

(4)  Includes an annuity valued at fair value. Other investments carried at cost are excluded. 

The fair values for securities included in the Level 2 category, with the few exceptions described 

below, have been developed by third party, nationally recognized pricing services. These services use 
complex methodologies to determine values for securities and subject the values they develop to quality 
control reviews. The services collect and utilize multiple inputs, although not all inputs are used for every 
security type or given the same priority in every evaluation. Inputs used include: benchmark yields, 
reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, and 
offers. The services also consider credit ratings, where appropriate, including ratings updates and 
information available in appropriate market research publications. Management reviews service-provided

values for reasonableness by comparing market yields indicated by the supplied value to yields observed 
in the market place. 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 2010 
or 2009.  

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 and agency obligations, and corporate bonds (exclusive of privately placed 
debt) 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.  

Municipal securities are valued using a series of matrices that consider credit ratings, the 
structure of the security, the sector in which the security falls, yields, and contractual cash flows. 
Valuations are further adjusted, when necessary, to reflect recent events such as significant economic or 
geographic events or ratings changes that would affect the security’s fair value.  

Mortgage backed securities. Agency pass through securities are valued by 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. Evaluations of Alt-A and subprime mortgages include a review of collateral 
performance data, which is generally updated monthly. 

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. 

Privately placed corporate debt is valued by an outside vendor rather than a third party pricing 
service. The valuation is prepared based on a widely available matrix that is produced daily by a leading 
seller of secondary private placements. The matrix considers the market sector, issuer credit ratings and 
the remaining loan term and is developed from market data such as interest rate yield curves, credit 
spreads, quoted market prices for comparable securities and other applicable market data. 

Bank loans are also valued by an outside vendor. The valuation is 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. 

Short term securities, primarily U. S. Treasury securities and commercial paper maturing within 

one year, are carried at cost which approximates the fair value of the security due to the short term to 
maturity.

December 31, 2010 

3.  Fair Value Measurement (continued) 

Below is a summary description of the valuation methodologies used to value securities in the 

Level 3 category by security type.  

Auction rate municipal bonds are valued internally using a model based on discounted cash flows 

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. All are rated A or better. 

Corporate debt instruments are valued internally using dealer quotes for similar securities or 

discounted cash flows 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. Corporate debt instruments include private placement senior notes valued at 
approximately $9.3 million and $12.0 million at December 31, 2010 and 2009, respectively. The notes are 
all rated A+ or better and are unconditionally guaranteed by large regional banks. The remaining Level 3 
corporate securities are not guaranteed or fully collateralized. Approximately $10.4 million and $10.5 
million at December 31, 2010 and 2009, respectively, have an average NRSRO rating of A-. 
Approximately $1.5 million and $1.8 million at December 31, 2010 and 2009, respectively, do not have 
an NRSRO rating. 

Asset-backed securities are valued using multiple inputs including multiple broker dealer quotes. 

Annuities are valued internally using a model based on discounted cash flows using yields 

currently available for similar investments. 

Interests in private investment funds are valued using the net asset value provided by the fund.  

The following table provides additional information regarding investments in private investment 

funds valued using the net asset value provided by the fund at December 31, 2010:

(1)  The fund 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 fund’s annual audit. 

(2)  The fund is structured to provide capital appreciation through diversified investments in 
private equity, including investments in buyout, venture capital, mezzanine, distressed 
debt and other private equity-oriented funds. Redemptions are not allowed, except by 
special permission of the fund. Fund proceeds are to be periodically distributed at the 
discretion of the fund over an anticipated time frame that spans 3 to 5 years. 

(3)  As discussed in Note 4, the fund was liquidated during 2010. Prior to liquidation, the fund 

consisted primarily of high-yield asset-backed securities.

Transfers between Level 3 categories during 2010 include: 

  At December 31, 2009 Other Investments total included asset-backed securities valued at $1 
million that were held in a private investment fund. During 2010 these securities were 
returned to direct ownership and were reclassified as Asset-backed securities (see Note 4 of 
the Notes to the Consolidated Financial Statements). Multiple observable inputs were not 
available for use in valuing the securities at either December 31, 2009 or 2010. 

Transfers from Level 2 to Level 3 during 2010 include: 

  Four corporate bonds having a combined value of $1.9 million. Multiple observable inputs 

were not available for use in valuing the bonds at December 31, 2010. 

Transfers from Level 3 to Level 2 during 2010 include: 

  Four corporate bonds having a combined value of $5.6 million. Multiple observable inputs 

were available for use in valuing the securities at December 31, 2010. Such information was 
not available for valuing the bonds at December 31, 2009. 

  A commercial mortgage-backed security valued at $1 million. Multiple observable inputs 

were available for use in valuing the security at December 31, 2010. 

  Beneficially owned asset-backed securities held in a private investment fund were 100% 

categorized as Level 3 at December 31, 2009 because valuations were determined by the fund 
manager using various methodologies, not all of which were based on multiple observable 
inputs. During 2010 the fund manager provided additional information regarding the 
valuation methodologies followed, and securities, having a combined fair value of $10.7 
million valued using multiple observable inputs were transferred to the Level 2 category.

Transfers from Level 2 into Level 3 during 2009 include: 

  Corporate bonds having a combined value of $5 million that were valued using multiple 

observable inputs at December 31, 2008. During 2009 such information was not available, 
and the bonds were valued using a single broker dealer quote. 

  Municipal bonds totaling $10 million. The bonds were valued using multiple observable 
inputs at December 31, 2008. Such inputs were unavailable in 2009 and the bonds were 
valued using a pricing model. 

 

Interests in private investment funds accounted for under the equity method valued using the 
net asset value provided by fund management. The interests were not included in the fair 
value table at December 31, 2008, but were included effective January 1, 2009 in compliance 
with GAAP guidance issued in 2009 specifying that such valuation constitutes valuation at 
fair value. 

Transfers from Level 3 into Level 2 during 2009 include:  

  A private placement bond valued at $4 million that was a new issue during 2008. There was 
no active market for the security or nearly identical security during the latter portion of 2008. 
Market activity increased in 2009, which provided multiple observable inputs that could be 
used to value the security. 

  Two corporate bonds, having a combined value of $2.2 million. The bonds were valued using 
a pricing model prior to December 31, 2009 due to the unavailability of multiple observable 
inputs. Multiple observable inputs were available at December 31, 2009 for use in valuing the 
bonds. 

  Asset-backed securities having a value of $0.5 million. There was no active market for the 

securities during the latter portion of 2008. Market activity increased in 2009, which provided 
multiple observable inputs that could be used to value the securities. 

  FHLB investments of $5.2 million are valued at cost, and, as such have been excluded from 

the table at December 31, 2009.

Fair Value Option Elections 

The 2019 Note Payable and a related interest rate swap agreement (the Swap) are measured at fair 

value on a recurring basis, with changes in the fair value of each liability recorded in net realized gains 
(losses).  ProAssurance assumed both liabilities as part of the PICA acquisition. The fair value option was 
elected for the 2019 Note Payable because valuation at fair value better reflects the economics of the 
related liabilities and eliminates the inconsistency that would otherwise result from carrying the 2019 
Note Payable on an amortized cost basis and the Swap at fair value.  

The 2019 Note Payable had an outstanding principal balance of $17.4 million at December 31, 

2010 and $17.7 million at December 31, 2009.

4.  Investments (continued) 

Excluding investments in bonds and notes of the U.S. Government, a U.S. Government agency, 

or pre-refunded state and municipal bonds which are 100% backed by U.S. Treasury obligations, no 
investment in any entity or its affiliates exceeded 10% of shareholders’ equity at December 31, 2010. 

At December 31, 2010, ProAssurance has available-for-sale securities with a fair value of $28.7 

million on deposit with various state insurance departments to meet regulatory requirements. 
ProAssurance also has available-for-sale securities with a fair value of $27.2 million that are pledged as 
collateral security for the 2019 Note Payable (see Note 10.) 

Business Owned Life Insurance (BOLI) 

ProAssurance holds BOLI policies on management employees that are carried at the current cash 
surrender value of the policies (original cost $35 million). The primary purpose of the program is to offset 
future employee benefit expenses through earnings on the cash value of the policies. ProAssurance is the 
owner and principal beneficiary of these policies. ProAssurance reduced its BOLI investment in 2010 by 
redeeming approximately $16 million of its cash surrender value. This redemption created taxable income 
triggering an additional tax liability of approximately $1.3 million, which was recognized during 2010. 

Other Investments 

ProAssurance has Other Investments comprised of the following:

FHLB capital stock is not marketable, but may be liquidated by terminating membership in the 

FHLB. The liquidation process can take up to five years. 

At December 31, 2009 ProAssurance, through its ownership of a separate interest in a private 

investment fund, held a direct beneficial interest in certain high yield asset-backed securities. The 
investment fund liquidated in July 2010 and distributed the securities to ProAssurance. The distributed 
securities were classified as available for sale fixed maturities. No gain or loss was recorded related to the 
distribution; however, Management determined at the time of distribution that the securities would be 
sold, and recognized impairment losses of $9.5 million related to the securities in 2010.

Unconsolidated Subsidiaries 

ProAssurance holds investments in unconsolidated subsidiaries, accounted for under the equity 

method. The investments include the following:

4.  Investments (continued) 

Investments in tax credit partnerships are comprised of multiple separate limited partner interests 

designed to generate investment returns by providing tax benefits to fund investors in the form of net 
operating losses and tax credits. The related properties are principally low income housing properties. The 
investment balance reflects the entire commitment to the partnership; commitments of approximately $47 
million have not been funded as of December 31, 2010. 

Other business interest consists of a non-controlling interest in a development stage limited 

liability company. The start-up phase is expected to continue for another twelve months. 

The long/short equity fund targets absolute returns using a strategy designed to take advantage of 

event-driven market opportunities. 

The non-public equity fund holds diversified private equities and is structured to provide capital 

appreciation. 

Investments Held in a Loss Position 

The following tables provide summarized information with respect to investments held in an

Notes to Consolidated Financial Statements 
December 31, 2010 

4.  Investments (continued) 

As of December 31, 2010, there were 510 debt securities (19% of all available-for-sale fixed 
maturity securities held) in an unrealized loss position representing 309 issuers. The single greatest 
unrealized loss position is approximately $0.8 million; the second greatest unrealized loss position is 
approximately $0.6 million. The securities were evaluated for impairment as of December 31, 2010. 

As of December 31, 2009, there were 344 debt securities (14% of all available-for-sale fixed 

maturity securities held) in an unrealized loss position representing 287 issuers.  

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 the Consolidated Financial Statements.  

At December 31, 2010 fixed maturity securities held in an unrealized loss position, 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 were estimated 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. Expected future cash flows from the equity interest 
carried in a loss position were also evaluated and are expected to equal or exceed the carrying value of the 
equity interest.

4.  Investments (continued) 

ProAssurance recognized an impairment loss of $9.5 million in 2010 related to certain high-yield 

securities that Management intended to sell, as previously discussed under the sub-header Other 
Investments. 

ProAssurance recognized an impairment of $3.4 million in 2010 related to an interest in a private 

investment fund, accounted for on a cost basis. The fund has reported realized losses on the sale of 
securities, and ProAssurance has reduced the carrying value of its interest in the fund in recognition of its 
pro rata share of those losses. 

ProAssurance recognized credit-related impairments in earnings of $3.0 million in 2010, 
including $1.5 million reclassified from OCI, related to residential mortgage-backed securities. Expected 
future cash flows were less than ProAssurance’s carrying value for these securities; therefore, 
ProAssurance reduced the carrying value of its interest in these securities and recognized the loss in its 
2010 net income. 

Net gains (losses) related to fixed maturities in the above table are $24.1 million, $4.5 million, and 

($32.0) million during 2010, 2009 and 2008, respectively. 

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 has been recorded

5.  Reinsurance 

ProAssurance has various excess of loss, quota share, and cession reinsurance agreements in 

place. Historically, the professional liability per claim retention level has varied between 90% and 100% 
of the first $1 million and between 0% and 5% of claims exceeding those levels depending on the 
coverage year and the state in which business was written. ProAssurance also insures some large 
professional liability risks that are above the limits of its basic reinsurance treaties. These risks are 
reinsured on a facultative basis, whereby the reinsurer agrees to insure a particular risk up to a designated 
limit.

The receivable from reinsurers on unpaid losses and loss adjustment expenses represents 
Management’s estimate of amounts that will be recoverable under ProAssurance reinsurance agreements. 
These estimates are based upon Management’s expectation of ultimate losses and the portion of those 
losses that are allocable to reinsurers according to the terms of the agreements. Given the uncertainty of 
the ultimate amounts of losses, Management’s estimates of losses and related amounts recoverable may 
vary significantly from the eventual outcome. Also, premiums ceded under reinsurance agreements 
wherein the premium due to the reinsurer, subject to certain maximums and minimums, is based in part 
on losses reimbursed or to be reimbursed under the agreement, and will thus vary when loss estimates are 
revised. During the year ended December 31, 2010 and December 31, 2009 ProAssurance reduced 
premiums ceded by $13.4 million and $6.2 million, respectively, due to changes in Management’s 
estimates of amount due to reinsurers related to prior accident year loss recoveries. 

Reinsurance contracts do not relieve ProAssurance from its obligations to policyholders and 

ProAssurance remains liable to its policyholders whether or not reinsurers honor their contractual 
obligations to ProAssurance. ProAssurance continually monitors its reinsurers to minimize its exposure to 
significant losses from reinsurer insolvencies. 

At December 31, $87.9 million of the total amounts due from reinsurers of $181.4 million 

(including receivables related to paid and unpaid losses and LAE and prepaid reinsurance premiums) is 
due from four reinsurers which have an individual balance which exceeds $10 million. Each of these 
reinsurers has an A.M. Best credit rating of AA or above. 

As of December 31, 2010 ProAssurance has not established an allowance for credit losses related 

to its reinsurance receivables. During the year ended December 31, 2010 no reinsurance balances were 
written off for credit reasons. 

At December 31, 2010, all reinsurance recoverables are considered collectible. Reinsurance 
recoverables totaling approximately $17.0 million are collateralized by letters of credit or funds withheld. 
At December 31, 2010 no amounts due from individual reinsurers exceed 5% of shareholders’ equity. 

There were no significant reinsurance commutations in 2010 or 2009. 

During 2008, ProAssurance commuted (terminated) various outstanding reinsurance 
arrangements for approximately $42.7 million in cash. The commutations reduced Receivable from 
Reinsurers on Paid Losses and Receivable from Reinsurers on Unpaid Losses, combined, by 
approximately $3.9 million (net of cash received) and reduced Reinsurance Premiums Payable by 
approximately $0.1 million.

In evaluating the need for a valuation allowance on deferred tax assets, management determined 

that assets related to capital losses on investments would be realized through a tax planning strategy of 
selling investments with built in gains.  

A valuation allowance of $0.9 million that was established in 2009 related to deferred tax assets 

acquired in the PICA acquisition was released in 2010. Management believes that sufficient sources of 
taxable income are available to realize the benefit of these deferred tax assets. 

At December 31, 2010 ProAssurance has no available net operating loss (NOL) carryforwards or 

Alternative Minimum Tax (AMT) credit carryforwards. ProAssurance has an available capital loss 
carryforward of $1.4 million that is subject to limitation under Internal Revenue Code Section 382. The 
capital loss carryforward will begin to expire in 2012. 

ProAssurance files income tax returns in the U.S. federal jurisdiction and various states. 
ProAssurance federal tax returns for the 2005 through 2008 tax years are currently under examination by 
the Internal Revenue Service. The Company’s Illinois state tax returns for the years 2006 through 2008 
are also under examination by the Illinois Department of Revenue. Management is not aware of any 
findings from these audits that would significantly alter ProAssurance current or deferred tax balances.

Unrecognized tax benefits at December 31, 2010, if recognized, would not affect the effective tax 
rate but would accelerate the payment of tax. ProAssurance’s uncertain tax positions are primarily timing 
differences related to the recognition of gains (losses) on certain marketable securities and the

Interest and penalties accrued or paid approximated $0.4 million during each of the years ended 
December 31, 2010 and 2009. The accrued liability for interest and penalties approximated $0.7 million 
and $0.4 million at December 31, 2010 and 2009, respectively. 

7.  Deferred Policy Acquisition Costs 

Policy acquisition costs, most significantly commissions, premium taxes, and underwriting 
salaries, that are primarily and directly related to the production of new and renewal premiums are 
capitalized as policy acquisition costs and amortized to expense as the related premium revenues are 
earned. 

Amortization of deferred policy acquisition costs is $58.9 million, $49.7 million, and $47.3 

million for the years ended December 31, 2010, 2009, and 2008, respectively.  

8.  Reserve for Losses and Loss Adjustment Expenses 

The reserve for losses is established based on estimates of individual claims and actuarially 

determined estimates of future losses based on ProAssurance’s past loss experience, available industry 
data and projections as to future claims frequency, severity, inflationary trends and settlement patterns. 
Estimating reserves, and particularly liability reserves, is a complex process. Claims may be resolved over 
an extended period of time, often five years or more, and may be subject to litigation. Estimating losses 
for liability claims requires ProAssurance to make and revise judgments and assessments regarding 
multiple uncertainties over an extended period of time. As a result, reserve estimates may vary 
significantly from the eventual outcome. The assumptions used in establishing ProAssurance’s reserves 
are regularly reviewed and updated by management as new data becomes available. Changes to estimates 
of previously established reserves are included in earnings in the period in which the estimate is changed. 

ProAssurance believes that the methods it uses to establish reserves are reasonable and 

appropriate. Each year, ProAssurance uses internal actuaries to review the reserve for losses of each 
insurance subsidiary. ProAssurance also engages external actuaries to review ProAssurance claims data 
and provide observations regarding cost trends, rate adequacy and ultimate loss costs. ProAssurance 
considers the views of the actuaries as well as other factors, such as known, anticipated or estimated 
changes in frequency and severity of claims and loss retention levels and premium rates, in establishing 
the amount of its reserve for losses. The statutory filings of each insurance company with the insurance 
regulators must be accompanied by an external actuary’s certification as to their respective reserves in 
accordance with the requirements of the National Association of Insurance Commissioners (NAIC).

As discussed in Note 1, estimating liability reserves is complex and requires the use of many 
assumptions. As time passes and ultimate losses for prior years are either known or become subject to 
a more precise estimation, ProAssurance increases or decreases the reserve estimates established in 
prior periods. The favorable development recognized in 2010 and 2009 primarily reflects reductions 
in the Company’s estimates of claim severity for the 2003 through 2007 accident years. The favorable 
development recognized in 2008 was primarily due to reductions in estimates of claims severity for 
the 2004, 2005, and 2006 accident years. Actuarial evaluations of both internal and industry actual 
claims data in 2010, 2009 and 2008 all indicated that claims severity (i.e., the average size of a claim) 
is increasing more slowly than was anticipated when the reserves for 2003 through 2007 were initially 
established.

ProAssurance is involved in various legal actions related to insurance policies and claims 

handling including, but not limited to, claims asserted by policyholders. ProAssurance has considered 
such legal actions in establishing its loss and loss adjustment expense reserves. The outcome of any 
individual legal action is not presently determinable for a number of reasons. For example, in the 
event that ProAssurance or its insureds receive adverse verdicts, post-trial motions may result in 
unfavorable rulings; any appeals that may be undertaken may be unsuccessful; ProAssurance may be 
unsuccessful in legal efforts to limit the scope of coverage available to its insureds; and ProAssurance 
may become a party to bad faith litigation over the payment of any judgment above an insured's 
policy limits. ProAssurance's management is of the opinion, based on consultation with legal counsel, 
that the resolution of these actions will not have a material adverse effect on ProAssurance's financial 
position. However, the ultimate cost of resolving these legal actions may differ from the reserves 
established, and the resulting difference could have a material effect on ProAssurance's results of 
operations for the period in which any such action is resolved. 

In 2009 a ProAssurance subsidiary, ProAssurance National Capital Insurance Company (PRA 
National), after an unsuccessful appeal, paid approximately $20.8 million to settle a judgment entered 
against PRA National in 2004 in favor of Columbia Hospital for Women Medical Center, Inc. (the 
CHW Judgment or the Judgment). ProAssurance recognized a liability of $19.5 million related to the 
Judgment in 2005 as a component of the fair value of assets acquired and liabilities assumed in the

acquisition of PRA National and accrued post-trial interest thereafter. The payment was a full 
settlement of the Judgment except with regard to a pending settlement setoff of less than $0.3 million. 

As a result of its acquisition of APS, ProAssurance assumed risk of loss related to some non-

claims related legal actions previously asserted against APS subsidiaries. ProAssurance included a 
liability of $5.6 million related to these actions as a component of the fair value of assets acquired and 
liabilities assumed in the purchase price allocation. The value of the reserve was based on 
Management’s assessment of the expected outcome of the actions and a reasonable estimate of losses 
expected to be incurred. 

ProAssurance has commitments to fund an additional $47 million to tax credit partnerships, 

primarily in 2011 and 2012. 

ProAssurance is involved in a number of operating leases primarily for office space and 

office equipment. The following is a schedule of future minimum lease payments for operating leases 
that had initial or remaining noncancelable lease terms in excess of one year as of December 31, 
2010.

ProAssurance’s outstanding long-term debt consists of the following:  

Trust Preferred Securities due 2034, unsecured. Bears interest at a variable rate of LIBOR plus 
3.85%, adjusted quarterly (4.1% at December 31, 2010). Estimated fair value at December

Trust Preferred Securities due 2034 (TPS) 

The TPS are uncollateralized and do not require maintenance of minimum financial 
covenants. The TPS mature in 2034, but have been redeemable with notice since May 2009. Payment 
of interest may be deferred for up to 20 consecutive quarters; however, stockholder dividends cannot 
be paid during any extended interest payment period or at any time the debentures are in default. 

The TPS were issued in 2004 by a trust (the Trust) formed by ProAssurance for the purpose 

of issuing the TPS and using the proceeds thereof, together with the equity proceeds received from

10.  Long-term Debt (continued) 

ProAssurance in the initial formation of the Trusts, to purchase variable rate subordinated debentures 
(the TPS Debentures) issued by ProAssurance. ProAssurance owns all voting securities of the Trust. 
The Trust uses the interest and principal from the TPS Debentures to meet the obligations of the TPS.  

ProAssurance has guaranteed that amounts paid to the Trust pursuant to its TPS Debentures 

will be remitted to the holders of the TPS. These guarantees, when taken together with the obligations 
of ProAssurance under the TPS Debentures (including obligations to pay related trust costs, fees, 
expenses, debt and obligations of the Trust other than with respect to the TPS), the Indentures 
pursuant to which the TPS debentures were issued, and the related trust agreement provide a full and 
unconditional guarantee of amounts due on the TPS. 

Surplus Notes Due 2034 (the Surplus Notes) 

The Surplus Notes are the unsecured obligations of ProAssurance Wisconsin Insurance 

Company (PRA Wisconsin), a ProAssurance subsidiary, and are subordinated and junior in the right 
of payment to all senior claims and senior indebtedness of PRA Wisconsin. The Surplus Notes, with 
proper notice, may be fully or partially redeemed prior to maturity.  

The Surplus Notes converted from a fixed rate of 7.7% to a variable rate based on LIBOR in 
May 2009. Each payment of interest and principal, including redemption, may be made only with the 
prior approval of the Office of the Commissioner of Insurance of the State of Wisconsin and only to 
the extent PRA Wisconsin has sufficient surplus to make such payment. 

2019 Note Payable and related Interest Rate Swap 

The 2019 Note Payable was assumed in ProAssurance’s acquisition of PICA and is a secured 

obligation of PICA. Principal and interest payable are paid monthly with the principal amortizing 
over the life of the loan. PICA is required to maintain collateral security for the loan in an amount at 
least equal to the outstanding principal balance. In accordance with GAAP, the 2019 Note Payable 
was recorded at its fair value on the PICA acquisition date, April 1, 2009. Additionally, ProAssurance 
elected to account for the 2019 Note Payable at fair value on a recurring basis and, accordingly, no 
accretion of the fair value purchase adjustment is being recorded. 

Future maturities of the 2019 Note Payable as of December 31, 2010 are as follows: 

2011 
$324,600 

2012 
$344,000 

2013 
$370,900 

2014 
$397,400 

2015 
$424,900 

Thereafter 
$15,574,400 

The terms of the 2019 Note Payable specify covenants that must be met by PICA. The 
covenants, which have been met for 2010 and 2009, are of the nature routinely associated with loans 
of this type and include: 

  a requirement that PICA maintain a debt service coverage ratio of 1:1, measured annually. 
The ratio is computed as net income (as defined by GAAP) plus depreciation, interest, 
amortization and income taxes divided by aggregate principal and interest payments on all of 
PICA’s debt. 

  a requirement that PICA maintain an A.M. Best insurance rating of B++ “Good” or better.  

  a restriction on the sale, lease or transfer of a substantial, material portion of PICA’s assets 

without the approval of the bank 
PICA is party to an interest rate swap agreement (the Swap) with the 2019 Note Payable 

issuing bank, the purpose of which is to reduce the market risk from changes in future interest rates 
relative to the 2019 Note Payable. The Swap fixes the interest rate related to the Note Payable at 6.6% 
until

Notes to Consolidated Financial Statements 
December 31, 2010 

10.  Long-term Debt (continued) 
February 1, 2019. The notional amount of the swap corresponds directly to the unamortized portion of 
the debt being hedged each month. Under the swap agreement, PICA agrees to exchange, at monthly 
intervals, the difference between the fixed-rate and the LIBOR variable rate by reference to the 
notional principal amount. The liability associated with the Swap measured at fair value on a 
recurring basis which approximates $3.7 million at December 31, 2010 and $2.9 million at December 
31, 2009. The Swap liability is classified as a part of other liabilities. 

Note Payable due February 2012 (the 2012 Note)  

The 2012 Note was issued by ProAssurance Casualty Company, a subsidiary of 

ProAssurance, in connection with the acquisition of Georgia Lawyers. The 2012 Note may be repaid, 
plus interest, before maturity without penalty or fee.  

Subordination  

As previously discussed, the Surplus Notes, the 2019 Note Payable and the 2012 Note are 

each individually obligations of a single ProAssurance subsidiary. The notes have not been 
guaranteed by ProAssurance or its other subsidiaries, and each note is effectively subordinated to the 
indebtedness and other liabilities, including insurance policy-related liabilities, of ProAssurance and 
its other subsidiaries.  

Credit Facility 

ProAssurance’s PICA subsidiary had a revolving credit facility with a bank in the amount of 

$3.0 million which expired on August 1, 2010, and was not renewed. 

Debt Extinguished 

As a part of the PICA acquisition, ProAssurance assumed liability for PICA’s Surplus Notes 
due May 2033 (the 2033 Surplus Notes) which had an outstanding principal balance of $7.0 million. 
ProAssurance redeemed the 2033 Surplus Notes at par, for cash, in August 2009. Because the 2033 
Surplus Notes were valued at fair value on the date of acquisition but were redeemed at par, 
ProAssurance incurred a pre-tax loss of approximately $2.8 million ($1.8 million, net of tax) related 
to the redemption. 

In December 2008, ProAssurance reacquired TPS having a face value of $23 million for cash 
of approximately $18.4 million and recognized a $4.6 million gain on the extinguishment of the debt.  

ProAssurance completed the conversion of all of its outstanding Convertible Debentures 

(aggregate principal of $107.6 million) in July 2008. Approximately 2,572,000 shares of 
ProAssurance common stock were issued in the transaction (conversion rate was 23.9037 per $1,000 
debenture). Of the common shares issued, approximately 2.12 million were reissued Treasury Shares 
and 450,000 were newly issued shares. No gain or loss was recorded related to the conversion. 

11.  Shareholders’ Equity 

At December 31, 2010 and December 31, 2009, ProAssurance had 100 million shares of 

authorized common stock and 50 million shares of authorized preferred stock. The Board of Directors 
of ProAssurance Corporation (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. 

118 

 
 
 
 
ProAssurance Corporation and Subsidiaries 
Notes to Consolidated Financial Statements 
December 31, 2010 

11.  Shareholders’ Equity (continued) 

At December 31, 2010 approximately 1.6 million of ProAssurance’s authorized common 

shares are reserved by the Board of Directors of ProAssurance for award or issuance under incentive 
compensation plans as described in Note 12. Additionally, at December 31, 2010 approximately 0.9 
million of ProAssurance’s authorized common shares are reserved by the Board of Directors of 
ProAssurance for the issuance of outstanding restricted share and performance share units and for the 
exercise of outstanding stock options. 

In November 2010, the Board increased its prior authorizations for the repurchase of common 

shares or the retirement of outstanding debt by $200 million. As of December 31, 2010, 
authorizations totaling $209.0 million remain available for use. The timing and quantity of purchases 
depends upon market conditions and changes in ProAssurance’s capital requirements and is subject to 
limitations that may be imposed on such purchases by applicable securities laws and regulations, and 
the rules of the New York Stock Exchange. 

ProAssurance used approximately $7.0 million and $18.4 million of the authorization to 

redeem debt during the years ended December 31, 2009 and 2008, respectively (see Note 10).  

ProAssurance repurchased approximately 1.9 million, 1.1 million, and 1.8 million common 

shares, having a total cost of $106.3 million, $52.0 million, and $87.6 million during the years ended 
December 31, 2010, 2009, and 2008, respectively. In July 2008 approximately 2.12 million treasury 
shares and 450,000 newly issued common shares were used to complete the conversion of 
ProAssurance's Convertible Debentures. The conversion of the debt increased Stockholders’ Equity 
by $112.5 million, consisting of the carrying amount of the Convertible Debentures (principal of 
$107.6 million, less the unamortized portion of related loan discounts and costs of $1.8 million) and a 
$6.7 million tax benefit from the reversal of interest-related deferred tax liabilities. No gain or loss 
was recognized on the conversion. 

For all periods presented, other comprehensive income is comprised of unrealized gains and 

losses, including non-credit impairment losses, (net of tax) arising during the period related to 
available-for-sale securities less reclassification adjustments for gains (losses) from available-for-sale 
securities recognized in current period net income. Accumulated other comprehensive income is 
comprised entirely of unrealized gains and losses from available for sale securities, net of tax. 

Reclassification adjustments related to available-for-sale securities for the years ended 

December 31, 2010, 2009 and 2008 are as follows:

impairment of debt securities, ProAssurance reclassified previously recognized non-credit impairment 
losses, net of tax, from retained earnings to accumulated comprehensive income (a $3.5 million 
increase to retained earnings; a $3.5 million decrease to accumulated other comprehensive income).  

12.  Stock Options and Share-Based Payments 

Share-based compensation costs are primarily classified as underwriting, policy acquisition 

and operating expenses.  

Since the beginning of 2009, ProAssurance has provided share-based compensation to 

employees under the ProAssurance Corporation 2008 Equity Incentive Plan. Previously, 
compensation was provided under the ProAssurance Corporation 2004 Equity Incentive Plan (2005 to 
2008) and the ProAssurance Corporation Incentive Compensation Stock Plan (prior to 2005). The

All awards are charged to expense as an increase to equity over the service period (generally

Stock Options 

ProAssurance’s stock options generally vest in five equal installments, the first installment 

occurring six months after the grant date and the other installments occurring annually thereafter. All 
options are granted with an exercise price equal to the market price of ProAssurance’s common 
shares on the date of grant, and an original term of ten years. ProAssurance option agreements permit 
a cashless exercise whereby the exercise price and any required tax withholdings are allowed to be 
satisfied by the retention of shares that would otherwise be deliverable to the option holder. 
ProAssurance issues new shares for options exercised.

There were no cash proceeds from options exercised during the years ended December 31, 

2010, 2009 or 2008. 

No stock options were granted during 2010 or 2009. In 2008 ProAssurance granted 132,500 

options having a weighted average grant date fair value of $16.49 per share, measured using the 
Black-Scholes option pricing model. Assumptions used in the model included a risk-free interest rate 
of 3.1%, expected volatility of 0.23, a dividend yield of 0.0%, and an expected average term of 6 
years. The risk-free interest rate was based on the rates for a U.S. Treasury instrument with a term 
similar to that of the option grant. Volatility was based on the historical volatility of ProAssurance’s 
common shares for the six-year period prior to the grant date. The dividend yield was assumed to be 
zero since ProAssurance has historically not paid dividends. Due to ProAssurance’s limited history of 
employee exercise behavior, the expected average term was estimated as the mid-point between the 
vesting date and the end of the contractual term of the option, as provided for by the U.S. Securities 
and Exchange Commission’s Staff Accounting Bulletin 107. 

Restricted Share Units 

ProAssurance first awarded restricted share units in 2009. In general, restricted share units 

vest at the end of a three year vesting period based upon a continued service requirement. Upon 
vesting, a portion of each award sufficient to satisfy the employee’s required tax withholdings will be 
paid to the employee in cash and the remainder of the award will be paid in shares. 

Activity for restricted share units during 2010 and 2009 is summarized below. Grant date fair 

values are based on the market value of a ProAssurance common share on the date of grant.

Performance share awards have been issued to two groups of employees: PRA executive 
officers and other managers. The awards 100% vest at the end of a three year period if the service 
requirements are met and minimum performance goals are achieved. If minimum performance goals 
are achieved, the payment of awards can vary from 75% to 125% of set targets depending upon the

The aggregate grant date fair value of target performance share units granted in 2010, 2009 

and 2008 totaled $5.1 million, $3.4 million and $4.0 million, respectively. ProAssurance issued 
approximately 52,000 shares to employees in 2010 related to performance share units granted in 
2007. ProAssurance issued approximately 44,000 shares to employees in 2009 related to performance 
share units granted in 2006. The aggregate intrinsic value of vested performance share units paid to 
employees in 2010 and 2009 (including cash tax withholdings) totaled $4.9 million and $3.5 million, 
respectively. The awards were issued at the maximum level (125% of the target) based on 
performance levels achieved. No performance share units were eligible for vesting in 2008. 

Bonus Compensation 

ProAssurance, with the approval of the Compensation Committee of the Board, issued 
common shares to employees as bonus compensation as follows: 2010 – 40,000; 2009 – 37,000; 2008 
– 60,000. The shares issued were valued at fair value on the award date, which is considered to be the 
market price of a ProAssurance common share.  

13.  Variable Interest Entities 

ProAssurance holds passive interests in a number of limited partnerships/limited liability 

companies that are considered to be Variable Interest Entities (VIEs) under GAAP guidance. 
ProAssurance has not consolidated these entities 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 
thus 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 
with any of the entities to provide other financial support to or on behalf of the entity. ProAssurance's 
maximum loss exposure relative to these investments is limited to the carrying value of 
ProAssurance's investment in the entity. 

The entities consist of 1) private investment funds formed for the purpose of achieving 
diversified equity and debt returns, 2) private investment funds formed to provide investment returns 
through the transfer of tax credits (principally federal or state tax credits related to federal low-income 
housing) and 3) a limited liability interest in a development stage business operation. In those 
instances where ProAssurance holds a minor interest in the entity, ProAssurance accounts for its

interest on a cost basis. Cost basis investments are included in Other Investments and have a carrying 
value of $31.2 million and $31.1 million at December 31, 2010 and December 31, 2009, respectively. 
In those instances where ProAssurance holds a greater than minor interest, ProAssurance accounts for 
its interest using the equity method. Equity method investments are included in Investment in 
Unconsolidated Subsidiaries and have a carrying value of $88.8 million at December 31, 2010 and 
$48.5 million at December 31, 2009. 

At December 31, 2009 ProAssurance held a direct and beneficial interest in certain high yield 

asset-backed bonds contributed to an investment fund created for the purpose of managing such 
investments. Under GAAP, this interest was considered to represent an interest in a separate VIE 
(commonly referred to as a silo), of which ProAssurance was the primary beneficiary. ProAssurance 
therefore consolidated its interest in these securities. The securities were included in Other 
Investments at fair value ($10.9 million at December 31, 2009). The fund liquidated in 2010, see Note 
4 of the Notes to the Consolidated Financial Statements for additional information.

Stock options are not dilutive when the option exercise price exceeds the average price of a 

common share during the period or when the result from assuming an option is exercised is a net 
decrease to outstanding shares. During the years ended December 31, 2010, 2009, and 2008, the 
average number of options not considered to be dilutive approximated 58,000 in 2010, 423,000 in 
2009, and 389,000 in 2008.

15.  Benefit Plans 

ProAssurance currently maintains a defined contribution savings and retirement plan that is 

intended to provide retirement income to eligible employees. The plan provides for employer 
contributions to the plan of between 5% and 10% of salary for qualified employees. APS and PICA 
maintained similar plans which were assumed by ProAssurance as a part of the acquisitions of APS 
and PICA. The PICA plan was merged into the ProAssurance plan in 2010 and the APS plan will be 
merged into the ProAssurance plan in 2011. ProAssurance incurred expense related to the savings and 
retirement plans of $6.1 million, $4.5 million and $3.5 million during the years ended December 31, 
2010, 2009 and 2008, respectively.  

ProAssurance also maintains a non-qualified deferred compensation plan (the ProAssurance 

Plan) that allows participating management employees to defer a portion of their current salary. 
ProAssurance incurred expense related to the ProAssurance Plan of $0.2 million, $0.3 million and 
$0.3 million for the years ended December 31, 2010, 2009 and 2008, respectively. 

ProAssurance has deferred compensation liabilities totaling $13.5 million at December 31, 

2010 and $6.6 million at December 31, 2009. The liabilities include amounts due under the 
ProAssurance Plan, amounts due under individual agreements with current employees or former 
employees of acquired entities, and amounts due under a currently inactive non-qualified plan.  

16.  Statutory Accounting and Dividend Restrictions 

ProAssurance's insurance subsidiaries are required to file statutory financial statements with 
state insurance regulatory authorities, prepared based upon statutory accounting practices prescribed 
or permitted by regulatory authorities. Differences between net income prepared in accordance with 
GAAP and statutory net income are principally due to: (a) policy acquisition and certain software and 
equipment costs which are deferred under GAAP but expensed for statutory purposes and (b) certain 
deferred income taxes which are recognized under GAAP but are not recognized for statutory 
purposes.  

The NAIC specifies risk-based capital requirements for property and casualty insurance 

providers. At December 31, 2010 statutory capital for each of ProAssurance’s insurance subsidiaries 
was sufficient to satisfy regulatory requirements. The table includes the statutory earnings of APS and 
PICA for the statutory annual period of the year of acquisition and thereafter (see Note 2). 
Consolidated net income, on a GAAP basis, includes the earnings of APS and PICA only for the 
periods following acquisition (November 2010 and April 2009, respectively).

ProAssurance’s insurance subsidiaries, in aggregate, are permitted to pay dividends of 
approximately $248 million during 2011 without prior approval. However, the payment of any 
dividend requires prior notice to the insurance regulator in the state of domicile and the regulator may 
prevent the dividend if, in its judgment, payment of the dividend would have an adverse effect on the 
surplus of the insurance subsidiary.

ProAssurance Corporation and Subsidiaries 
Schedule II – Condensed Financial Information of Registrant 

Notes to Condensed Financial Statements of Registrant 

1.  Basis of Presentation 

The registrant-only financial statements should be read in conjunction with ProAssurance 

Corporation’s (PRA Parent) consolidated financial statements. At December 31, 2010 and 2009, PRA 
Parent’s investment in subsidiaries is stated at the initial consolidation value plus equity in the 
undistributed earnings of subsidiaries since the date of acquisition. 

2.  Acquisitions/Dispositions 

On November 30, 2010 ProAssurance acquired 100% of the outstanding shares of American 
Physicians Service Group, Inc. (APS) for approximately $237.1 million. The acquisition is described 
in Note 2 to the Consolidated Financial Statements. 

On April 1, 2009 ProAssurance acquired Podiatry Insurance Company of America and 
subsidiaries (PICA) through a cash sponsored demutualization. ProAssurance purchased all of 
PICA’s outstanding stock created in the demutualization for $120 million in cash and $15 million in 
premium credits. The acquisition is described in Note 2 to the Consolidated Financial Statements.  

3.  Long-term Debt 

Outstanding long-term debt, as of December 31, 2010 and December 31, 2009, consisted of 

the following: 

Trust  Preferred  Securities/Trust  Preferred  Subordinated  Debentures  due  2034,  unsecured, 
bearing  interest  at  a  variable  rate  of  LIBOR  plus  3.85%,  adjusted  quarterly  (4.1%  at 
December 31, 2010) (see below) 

  $  22,992 

  $  22,992 

(In thousands) 

2010 

2009 

In 2008, wholly owned subsidiaries of ProAssurance reacquired outstanding Trust Preferred 

Securities having a face value of $23 million, which effectively extinguished the related Trust 
Preferred Debentures issued by PRA Parent. Trust Preferred amounts shown in the above table are 
shown net of the reacquired Trust Preferred Securities held by PRA Parent’s subsidiaries. A gain of 
$4.6 million was recognized on the extinguishment of the debt. 

In 2009, PRA Parent retired $13.4 million of the Trust Preferred Securities held by its 

subsidiaries. 

See Note 10 of the Notes to the Consolidated Financial Statements included herein for a 

detailed description of the terms of the long-term debt. 

4.  Related Party Transactions 

PRA Parent received dividends from its subsidiaries of $232.8 million, $221.5 million and 
$104.8 million during the years ended December 31, 2010, 2009 and 2008. PRA Parent contributed 
capital to its subsidiaries of $10.0 million, $35.0 million and $0.5 million during the years ended 
December 31, 2010, 2009 and 2008. 

5.  Income Taxes 

Under terms of PRA Parent’s tax sharing agreement with its subsidiaries, income tax 

provisions for individual companies are allocated on a separate company basis.

Annual Report Appendix A 

Non-GAAP Financial Measures 

Operating Income is a “Non-GAAP” financial measure that is widely used in our industry to evaluate 
the performance of underwriting operations. Operating Income excludes the after-tax effects of net realized 
gains or losses and guaranty fund assessments or recoupments and debt retirement loss. We believe it 
presents a useful view of the performance of our insurance operations. While we believe disclosure of certain 
Non-GAAP information is appropriate, you should not consider this information without also considering the 
information we present in accordance with GAAP, which includes the effect of net realized gains or losses 
and guaranty fund assessments or recoupments incurred during the periods presented below. The following 
table reconciles Income from Continuing Operations to Operating Income.
