Syndicate results can be affected by decisions made by the Council of Lloyd's which the management of Syndicate
1729 and Syndicate 6131 have little ability to control, such as a decision to not approve the business plan of
Syndicate 1729 or Syndicate 6131, or a decision to increase the capital required to continue operations, and by our
obligation to pay levies to Lloyd's;
Lloyd's insurance and reinsurance relationships and distribution channels could be disrupted or Lloyd's trading
licenses could be revoked, making it more difficult for a Lloyd's Syndicate to distribute and market its products;

rating agencies could downgrade their ratings of Lloyd's as a whole; and

Syndicate 1729 and Syndicate 6131 operations are dependent on a small, specialized management team, and the loss
of their services could adversely affect the Syndicate’s business. The inability to identify, hire and retain other highly
qualified personnel in the future could adversely affect the quality and profitability of Syndicate 1729’s or Syndicate
6131's business.

Our Values
Integrity, Leadership, Relationships, Enthusiasm

ProAssurance is a U.S. based specialty property and casualty and workers' compensation insurance carrier. Our specialty 
property and casualty insurance products primarily include professional liability insurance and liability insurance for medical 
technology and life sciences risks. We also provide capital to Syndicate 1729 which writes a range of property and casualty 
insurance and reinsurance lines. In addition, we are a capital provider of an SPA, Syndicate 6131, which focuses on 
contingency and specialty property business.

Our executive offices are located at 100 Brookwood Place, Birmingham, Alabama 35209 and our telephone number is 

(205) 877-4400. Our stock trades on the NYSE under the symbol “PRA.” Our website is www.proassurance.com, and we
maintain a dedicated Investor Relations section on that website (investor.proassurance.com) to provide specialized resources for
investors and others seeking to learn more about us.

As part of our disclosure through the Investor Relations section of our website, we publish our annual report on Form 10-

K, our quarterly reports on Form 10-Q and our current reports on Form 8-K and all other public SEC filings as soon as 
reasonably practicable after the report is electronically filed with, or furnished to, the SEC. These SEC filings can be found on 
our website at investor.proassurance.com/Docs. This section also includes information regarding stock trading by corporate

Our History

We were incorporated in Delaware in 2001 as the successor to Medical Assurance, Inc, in conjunction with its merger 
with Professionals Group, Inc. ProAssurance has a history of growth through acquisitions; the most significant and recent of 
which was the acquisition of Eastern Insurance Holdings, Inc., on January 1, 2014. On February 20, 2020, we entered into a 
definitive agreement to acquire NORCAL, an underwriter of medical professional liability insurance, subject to the 
demutualization of NORCAL Mutual, NORCAL's ultimate controlling party. Upon satisfaction of the various remaining 
regulatory approvals required, we are anticipating to close the transaction in the second quarter of 2021. If consummated, the 
transaction will provide strategic and financial benefits including additional scale and geographic diversification in the 
physician professional liability market.

Our Strategy

We seek to generate an attractive total return for our shareholders while focusing on our culture and people. The basic 

components of our strategy for achieving this objective are as follows:

• Pursue profitable underwriting opportunities. We emphasize profitability, not market share, and strive to achieve a

consistent level of underwriting profit over the various economic and insurance cycles. Key elements of our
approach are adhering to disciplined underwriting principles, including prudent risk selection and appropriate
pricing, as well as adjusting our business mix as necessary to effectively utilize capital and achieve long-term profit
objectives.

• Focus on culture and people. We strive to be the Employer of Choice by attracting, retaining and developing a
diverse group of employees who embody our Mission, Vision and Values. We are committed to fostering an
inclusive workplace in which variety of thought, creativity and innovation fuels employee engagement and
ultimately increases shareholder return. See further discussion on our employees and culture within this section
under the heading "Human Capital Resources."

• Provide specialized healthcare-centric expertise to meet evolving demands in the healthcare marketplace. Through

our focus on healthcare, we provide traditional liability insurance products to healthcare providers. We also
leverage our reach, expertise and financial strength to provide innovative and customized products to meet the risk
management needs of larger healthcare organizations or groups.

• Provide superior workers' compensation products and services. We provide workers' compensation products and
services that focus on increasing an organization's productivity while reducing costs. We do this by providing
innovative programs and solutions that address the specific needs of our customers and return injured workers to
wellness and the dignity of work.

• Provide superior customer service. Our mission statement, "We exist to Protect Others," goes hand-in-hand with

our corporate brand promise, "Treated Fairly." Our employees demonstrate our core values of integrity, leadership,
relationships and enthusiasm every day and are focused on meeting the needs of our customers.

• Focus on operational excellence. Improve our competitive position by focusing on operational excellence and

productivity gains by leveraging technology, streamline operations, workflow improvements and proactive expense
management.

• Effectively manage capital. We carefully monitor use of our capital and consider various options for capital
deployment, such as business expansion by our existing subsidiaries, opportunities that arise for mergers or
acquisitions, share repurchases and payment of dividends.

• Manage claims effectively. Our experienced claims teams have industry and insurance expertise that, with our

extensive local knowledge, allows us to resolve claims in an effective manner, considering the circumstances of
each claim. When practicable, we utilize formalized claims management processes and protocols as a means of
reducing claim costs.

• Emphasize risk management. We actively manage our enterprise risk by maintaining strong internal controls. We
also emphasize the importance of risk management to our insureds and offer them training in the use of risk
reduction tools and techniques.

• Maintain a conservative investment strategy. We believe that we follow a conservative investment strategy

designed to emphasize the preservation of our capital and provide adequate liquidity for the prompt payment of
claims. Our investment portfolio consists primarily of investment-grade, fixed-maturity securities of short-to
medium-term duration.

• Maintain financial stability. We are committed to maintaining financial strength and adequate capital.

Organization and Segment Information

We operate through multiple insurance organizations and report our financial results in five segments, as follows:

•

Specialty P&C - This segment includes our professional liability business and medical technology liability
business. Our professional liability insurance is primarily comprised of medical professional liability products
offered to healthcare providers and institutions. We also offer, to a lesser extent, professional liability insurance to
attorneys and their firms. Medical technology liability insurance is offered to medical technology and life sciences
companies that manufacture or distribute products including entities conducting human clinical trials. We also offer
custom alternative risk solutions including loss portfolio transfers, assumed reinsurance and captive cell programs
for healthcare professional liability insureds. For our alternative market captive cell programs, we cede either all or
a portion of the premium to certain SPCs in our Segregated Portfolio Cell Reinsurance segment.

10

• Workers' Compensation Insurance - This segment includes our workers' compensation insurance business which is
provided generally to employers with 1,000 or fewer employees. Our workers' compensation products include
guaranteed cost policies, policyholder dividend policies, retrospectively-rated policies, deductible policies and
alternative market solutions. Alternative market solutions include program design, fronting, claims administration,
risk management, SPC rental, asset management and SPC management services. Alternative market premiums are
100% ceded to either SPCs in our Segregated Portfolio Cell Reinsurance segment or, to a limited extent, an
unaffiliated captive insurer.

•

Segregated Portfolio Cell Reinsurance - This segment includes the results (underwriting profit or loss, plus
investment results, net of U.S. federal income taxes) of SPCs at Inova Re and Eastern Re, our Cayman Islands SPC
operations. Each SPC is owned, fully or in part, by an agency, group or association and the results of the SPCs are
attributable to the participants of that cell. We participate to a varying degree in the results of selected SPCs and,
for the SPCs in which we participate, our participation interest ranges from a low of 20% to a high of 85%. SPC
results attributable to external cell participants are reflected as an SPC dividend expense (income) in our
Segregated Portfolio Cell Reinsurance segment. The SPCs assume workers' compensation insurance, healthcare
professional liability insurance or a combination of the two from our Workers' Compensation Insurance and
Specialty P&C segments.

• Lloyd's Syndicates - This segment includes the results from our participation in Lloyd's of London Syndicate 1729
and Syndicate 6131. The results of this segment are normally reported on a quarter lag, except when information is
available that is material to the current period. Syndicate 6131 is an SPA that underwrites on a quota share basis
with Syndicate 1729. Syndicate 1729 underwrites risks over a wide range of property and casualty insurance and
reinsurance lines in both the U.S. and international markets while Syndicate 6131 focuses on contingency and
specialty property business, also within the U.S. and international markets.

• Corporate - This segment includes our investment operations, other than those reported in our Segregated Portfolio
Cell Reinsurance and Lloyd's Syndicates segments, interest expense and U.S. income taxes. This segment also
includes non-premium revenues generated outside of our insurance entities and corporate expenses.

(1) Primarily comprised of twelve month term policies, but includes premium related to policies with a twenty-four month term of $8.3 million
in 2020, $26.9 million in 2019 and $27.4 million in 2018. The majority of renewed twenty-four month term policies were re-underwritten
to twelve month term policies as we have ceased offering twenty-four month term policies beginning in the second quarter of 2020.
(2) Premiums in our Segregated Portfolio Cell Reinsurance segment are predominately assumed from either our Workers' Compensation

Insurance or Specialty P&C segments. We eliminate this inter-segment revenue.

(3) Our written premium includes our participation in Syndicates 1729 and 6131, including casualty premium assumed in 2018 by Syndicate
1729 from our Specialty P&C segment through a previous quota share reinsurance agreement. We eliminate this inter-segment revenue.
There was no premium assumed by Syndicate 1729 from our Specialty P&C segment during 2020 or 2019.

Assets are not allocated to segments because investments, other than the investments that are solely allocated to the 
Segregated Portfolio Cell Reinsurance and Lloyd's Syndicates segments, and other assets are not managed at the segment level. 
Additional detailed information regarding premium by individual product type within each of our insurance segments is 
provided in Item 7, Management's Discussion and Analysis, in the Results of Operations section, under the headings "Premiums 
Written."

Our insurance exposures are primarily within the U.S. As a result of our participation in Lloyd's Syndicates 1729 and 

6131, we had net written premium of $22.6 million in 2020, $32.8 million in 2019 and $29.3 million in 2018 associated with 
insurance exposures outside of the U.S. In addition, we had net written premium of $11.1 million and $8.8 million in 2020 and 
2019, respectively, associated with international insurance exposures within our Specialty P&C segment.

11

Specialty Property and Casualty Segment

Our Specialty P&C segment focuses on professional liability insurance and medical technology liability insurance. 
Professional liability insurance is primarily offered to healthcare providers and institutions and, to a lesser extent, to attorneys 
and their firms. Medical technology liability insurance is offered to medical technology and life sciences companies that 
manufacture or distribute products including entities conducting human clinical trials.

Professional Liability Insurance

Our professional liability business is primarily focused on providing professional liability insurance to healthcare 

providers. We target the full spectrum of the HCPL market, covering multiple categories of healthcare professionals, 
institutions (which includes hospitals, surgery centers and miscellaneous medical facilities) and, to a lesser extent, facilities 
specializing in long term residential care. While a majority of our business is written in the Standard market, we also offer 
professional liability insurance on an excess and surplus lines basis through our Specialty line of business; and we offer 
alternative risk and self-insurance products on a customized basis. 

Our custom alternative risk solutions include assumed reinsurance and a loss portfolio transfer program for healthcare 

entities who, most commonly, are exiting a line of business, changing an insurance approach or simply looking for a more 
tailored solution for transferring risk. Our custom alternative risk solutions also include a turnkey captive solution whereby we 
cede all or a portion of the healthcare premium, net of reinsurance, to three SPCs of our wholly owned Cayman Islands 
reinsurance subsidiaries, Inova Re and Eastern Re, which are reported in our Segregated Portfolio Cell Reinsurance segment. 
Each SPC is owned, fully or in part, by an agency, group or association, and we currently have a 25% participation interest in 
the results of one of these three SPCs. See further discussion that follows under the heading "Segregated Portfolio Cell 
Reinsurance Segment." The portion not ceded to the SPCs is retained within our Specialty P&C segment. Total gross premiums 
written in this segment in our alternative market captive cell program were approximately $7.1 million, $7.8 million and $5.8 
million during 2020, 2019 and 2018, respectively.

We utilize independent agencies and brokers as well as an internal sales force to write our HCPL business. For the year 

ended December 31, 2020, approximately 76% of our HCPL gross premiums written were produced through independent 
insurance agencies or brokers. The agencies and brokers we use typically sell through healthcare insurance specialists who are 
able to convey the factors that differentiate our professional liability insurance products. In 2020, our ten largest agents or 
brokers produced approximately 32% of our HCPL premium; individually, no one agency or broker produced more than 7% of 
our HCPL premium.

In marketing our professional liability products we emphasize our financial strength, product flexibility and excellent 

claims, underwriting and risk resource services. We market our insurance products through our direct sales force and through 
our agents as well as direct mailings and advertising in industry-related publications. We also are involved in professional 
societies and related organizations and support legislation that will have a positive effect on healthcare and legal liability issues. 
We maintain regional underwriting offices which permit us to consistently provide a high level of services to customers on a 
local basis.

We maintain claim processing centers where our internal claims personnel investigate and monitor the processing of our 

professional liability claims. We engage experienced, independent litigation attorneys in each venue to assist with the claims 
process as we believe this practice aids us in providing a defense that is aggressive, effective and cost-efficient. We evaluate the 
merit of each claim and determine the appropriate strategy for resolution of the claim, either seeking a reasonable good faith 
settlement appropriate for the circumstances of the claim or aggressively defending the claim. As part of the evaluation and 
preparation process for HCPL 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 also provide professional liability coverage to attorneys and their firms in select areas of practice, which is a part of 
our Small Business Unit. Our legal professional liability coverage is a less significant portion of our business, accounting for 
approximately 3% of our 2020 gross premiums written. This business offers errors and omissions liability insurance policies for 
law firms engaged in the private practice of law. The program generally insures solo practitioners and smaller firms; almost all 
of our insured attorneys are members of a firm employing five or fewer attorneys. The areas of practice of our insured firms 
include plaintiff, real estate, criminal defense and general corporate law. The program does not insure firms practicing in areas 
that are considered high hazard such as securities and intellectual property law. 

Underwriting decisions for our legal professional liability coverage consider the firm’s areas of practice, the experience of 
the attorneys and the management controls and loss mitigation practices of the applicant. Our legal professional liability line of 
business operates in 33 states written through independent brokers. Brokers are appointed and must specialize in legal 
professional liability. The territory of appointed brokers is restricted to a state or a small number of states in order to maintain a 
level of exclusivity. 

12

Medical Technology and Life Sciences Insurance

Our medical technology liability business offers products-completed operations liability as well as errors and omissions 
liability insurance policies, on both a primary and excess basis, for medical technology and life sciences companies. The vast 
majority of these companies and the products they manufacture and/or distribute are regulated by the U.S. Food and Drug 
Administration or similar regulatory authorities in foreign jurisdictions. Products insured cover a broad array of medical devices 
and pharmaceuticals including imaging and non-invasive diagnostic devices, clinical lab instruments, medical instruments and 
surgical supplies, dental products, orthopedic implants, animal pharmaceuticals and medical devices, durable medical 
equipment and prescription and over-the-counter drugs. We also provide coverage for sponsors of clinical trials.

Underwriting analysis for medical technology liability encompasses the product's risk profile, loss history, the amount of 

coverage being sought, level of the insured's retention, expertise and experience of the applicant and the expected volume of 
product sales. Almost all of our medical technology liability business is written through independent brokers. In 2020, our top 
ten largest brokers generated approximately 41% of our medical technology liability gross written premium, with no one broker 
representing more than 9%. We do not appoint agents for our medical technology liability business. We defend our medical 
technology liability claims vigorously, with a negotiated settlement being the most frequent means of resolution.

Workers' Compensation Insurance Segment

Our Workers' Compensation Insurance segment offers workers' compensation products primarily in 19 core states in the 

Mid-Atlantic, Southeast, Midwest, Gulf South and New England regions of the continental U.S. Our workers' compensation 
business consists of two major business activities:

• Traditional workers' compensation insurance coverages provided to employers, generally those with 1,000

employees or less. Types of policies offered include guaranteed cost policies, policyholder dividend policies,
retrospectively-rated policies and deductible policies.

• Alternative market workers' compensation solutions provided to individual companies, groups or associations

whereby the workers' compensation premium written is 100% ceded to either the SPCs at Inova Re or Eastern Re,
which are reported in our Segregated Portfolio Cell Reinsurance segment, or, to a limited extent, a captive insurer
unaffiliated with ProAssurance. Alternative market solutions include program design, fronting, claims
administration, risk management, SPC rental, asset management and SPC management services. Of our total
alternative market premiums written, approximately 96% in 2020 and 97% in 2019 was ceded to the SPCs at Inova
Re and Eastern Re.

All of our workers' compensation products are distributed through a group of appointed independent agents.

We utilize an individual account underwriting strategy for our workers' compensation business that is focused on selecting 

quality accounts. Our goal is to underwrite a diverse book of business with respect to risk classification, hazard level and 
geographic location. We target accounts with strong return to wellness and safety programs in primarily low to middle hazard 
levels such as clerical offices, light manufacturing, healthcare, auto dealers and service industries and maintain a strong risk 
management unit in order to better serve our customers' needs.

We actively seek to reduce our workers' compensation loss costs by placing a concentrated focus on returning injured 

workers to wellness and the dignity of work as quickly as possible. We emphasize early intervention and aggressive disability 
management, utilizing in-house and third-party specialists for case management, including medical cost management. Strategic 
vendor relationships have been established to reduce medical claim costs and include preferred provider, physical therapy, 
prescription drug and catastrophic medical services.

Segregated Portfolio Cell Reinsurance Segment

Our Segregated Portfolio Cell Reinsurance segment includes the results (underwriting profit or loss, plus investment 
results, net of U.S. federal income taxes) of SPCs at Inova Re and Eastern Re, our Cayman Islands SPC operations. Each SPC 
is owned, fully or in part, by an agency, group or association and the results of the SPCs are attributable to the participants of 
that cell. We participate to a varying degree in the results of certain SPCs and, for the SPCs in which we participate, our 
participation interest ranges from a low of 20% to a high of 85% as of December 31, 2020. Each SPC is operated solely for the 
benefit of its cell participants, and the pool of assets of one SPC are statutorily protected from the creditors of any other SPC. 
The results of the SPCs are allocated among the cell participants in accordance with the terms of the cell agreements. SPC 
results attributable to external cell participants are reflected as an SPC dividend expense (income) in our Segregated Portfolio 
Cell Reinsurance segment. In addition, the Segregated Portfolio Cell Reinsurance segment includes the investment results of the 
SPCs as the investments are solely for the benefit of the cell participants. The segment results reflect our share of the results of 
the SPCs in which we participate. The SPCs assume workers' compensation insurance, healthcare professional liability 
insurance or a combination of the two from our Workers' Compensation Insurance and Specialty P&C segments.

13

The underwriting, marketing and distribution of policies written in alternative market programs are the same as that of the 

segment from which the policy was assumed: Workers' Compensation Insurance or Specialty P&C segments.

Lloyd's Syndicates Segment

Our Lloyd's Syndicates segment includes the results from our participation in Syndicates 1729 and 6131. The results of 

this segment are normally reported on a quarter lag, except when information is available that is material to the current period. 
Furthermore, investment results associated with investment assets solely allocated to Lloyd's Syndicate operations and certain 
U.S. paid administrative expenses are reported concurrently as that information is available on an earlier time frame. We have 
investments in and obligations to Syndicate 1729 and Syndicate 6131 consisting of a Syndicate Credit Agreement, FAL 
requirements and our participation in results. The Syndicate Credit Agreement was issued for the purpose of providing working 
capital to Syndicate 1729 with maximum permitted borrowings of £30.0 million. We provide FAL to support underwriting by 
Syndicate 1729 and Syndicate 6131 which is comprised of investment securities and cash and cash equivalents deposited with 
Lloyd's with a total fair value of approximately $106.2 million at December 31, 2020. See further discussion on the Syndicate 
Credit Agreement and our FAL in Note 3 of the Notes to Consolidated Financial Statements. The underwriting capacity of 
Syndicate 1729 and Syndicate 6131 and our respective participation in each for the 2021 underwriting year is discussed in the 
following paragraphs.

Lloyd's Syndicate 1729

We provide capital to Syndicate 1729, which covers a range of property and casualty insurance and reinsurance lines in 

both the U.S. and international markets. The remaining capital for Syndicate 1729 is provided by unrelated third parties, 
including private names and other corporate members. To support and grow our core insurance operations, we decreased our 
participation in the results of Syndicate 1729 for the 2021 underwriting year to 5% from 29%. Syndicate 1729's maximum 
underwriting capacity for the 2021 underwriting year is £185 million (approximately $253 million at December 31, 2020), of 
which £9 million (approximately $13 million at December 31, 2020) is our allocated underwriting capacity.

Lloyd's Syndicate 6131

We provide capital to Syndicate 6131, which focuses on contingency and specialty property business, primarily for risks 
within the U.S. as well as international markets. As an SPA, Syndicate 6131 underwrites on a quota share basis with Syndicate 
1729. Effective July 1, 2020, Syndicate 6131, entered into a six-month quota share reinsurance agreement with an unaffiliated 
insurer. Under this agreement, Syndicate 6131 ceded essentially half of the premium assumed from Syndicate 1729 to the 
unaffiliated insurer; the agreement was non-renewed on January 1, 2021 and we decreased our participation in the results of 
Syndicate 6131 to 50% from 100% for the 2021 underwriting year. Syndicate 6131's maximum underwriting capacity for the 
2021 underwriting year is £20 million (approximately $27 million at December 31, 2020), of which £10 million (approximately 
$14 million at December 31, 2020) is our allocated underwriting capacity.

Our Lloyd's Syndicates segment products are distributed principally through retail brokers and coverholders (i.e., only 

those authorized by our retail brokers to enter into a contract but only in accordance with specified terms), which consist 
primarily of premium written through open-market channels and delegated underwriting authority arrangements. Our Lloyd's 
Syndicates write business in the Lloyd's marketplace and have access to international markets across the world.

Corporate Segment

Our Corporate segment includes our investment operations, other than those reported in our Segregated Portfolio Cell 
Reinsurance and Lloyd's Syndicates segments, interest expense and U.S. income taxes. The segment also includes non-premium 
revenues generated outside of our insurance entities and corporate expenses. We apply a consistent management strategy to the 
entire investment portfolio managed at the corporate level. Accordingly, we report those investment results and net realized 
investment gains and losses within our Corporate segment. Our overall investment strategy is to maximize current income from 
our investment portfolio while maintaining safety, liquidity, duration targets and portfolio diversification. The portfolio is 
generally managed by professional third-party asset managers whose results we monitor and evaluate. The asset managers 
typically have the authority to make investment decisions within the asset classes they are responsible for managing, subject to 
our investment policy and oversight, including a requirement that available-for-sale securities in a loss position cannot be sold 
without specific authorization from us. See Note 3 of the Notes to Consolidated Financial Statements for more information on 
our investments.

Competition

The marketplace for all our lines of business is very competitive. Within the U.S. our competitors are primarily domestic 
insurance companies and range from large national insurers whose financial strength and resources may be greater than ours to 
smaller insurance entities that concentrate on a single state and as a result have an extensive knowledge of the local markets. 
Additionally, there are many providers, domestic and international, of alternative risk management solutions. Syndicate 1729 
and Syndicate 6131, which are based in the U.K., face significant competition from other Lloyd's syndicates as well as other 

14

international and domestic insurance and reinsurance firms operating in the country of the insured. Competitive distinctions 
include pricing, size, name recognition, service quality, market commitment, market conditions, breadth and flexibility of 
coverage, method of sale, financial stability, ratings assigned by rating agencies and regulatory conditions. 

The changing healthcare environment within the U.S. during the past several years is providing both increased 

competitive challenges and opportunities for our largest segment, the Specialty P&C segment. Many physicians now practice as 
employees of larger healthcare entities. Further, healthcare services are increasingly provided by professionals other than 
physicians and outside of a traditional hospital or clinic setting. Such trends are widely expected to continue. Larger healthcare 
entities have customer service and risk management needs that differ from the traditional solo or small physician groups. Larger 
entities are more likely to combine risks such as workers' compensation and professional liability when purchasing insurance 
and are also more likely to manage all or a part of their risk through alternative insurance mechanisms. We have addressed 
these issues by enhancing our existing hospital/physician insurance programs, expanding our coverage of healthcare providers 
other than physician or hospitals, expanding our coverages to include workers' compensation and product liability, and by 
enhancing our customer service capabilities, particularly with regard to the needs of larger accounts. We continue to focus on 
offering unique, joint or cooperative insurance programs that are attractive to larger healthcare entities.

The workers’ compensation industry is highly competitive in the geographic markets in which we operate. New business 
opportunities, renewal pricing and retention continue to be a challenge as a result of intense competition, especially from multi-
line insurers that are willing to underprice their workers’ compensation products to offset other coverages and we expect this 
trend to continue in 2021. We believe our product offerings allow us to provide flexibility in offering workers’ compensation 
solutions to our customers at a competitive price. In addition, we believe that our claims handling and risk management services 
are attractive to our customers and provide us with a competitive advantage even when our pricing is higher than our 
competitors.

For all of our business, we recognize the importance of providing our products at competitive rates, but we do not price 

our products at rates that will not permit us to meet our long-term profit targets over the life of the insurance cycle. We base our 
rates on current loss projections, maintaining a long-term focus even when this approach may reduce our top line growth and 
result in us not meeting profit targets during certain phases of the insurance cycle. We believe that our size, reputation for 
effective claims management, unique customer service focus, multi-state presence and broad spectrum of coverages offered 
provides us with competitive advantages, even as the needs of our insureds change.

Rating Agencies

Our claims paying ability is regularly evaluated and rated by three major rating agencies: A.M. Best, Fitch and Moody’s. 

In developing their claims paying ratings, these agencies make an independent evaluation of an insurer’s ability to meet its 
obligations to policyholders. See "Risk Factors" for a table presenting the claims paying ratings of our principal insurance 
operations.

Our ability to service current debt and potential debt is regularly evaluated and rated by four rating agencies: A.M. Best, 
S&P, Fitch and Moody’s. These financial strength ratings reflect each agency’s independent evaluation of our ability to meet 
our obligation to holders of our debt, if any. While financial strength ratings may be of greater interest to investors than our 
claims paying ratings, these ratings are not evaluations of our equity securities nor a recommendation to buy, hold or sell our 
equity securities.

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 primarily domiciled in the U.S. Our states of domicile include Alabama, Illinois, Michigan, 
Pennsylvania and Vermont. Our foreign jurisdictions include our reinsurance operations based in the Cayman Islands, a 
territory of the U.K., and, through our participation in Lloyd's Syndicates, our insurance and reinsurance operations based in the 
U.K.

United States

Our insurance subsidiaries are required to file detailed annual statements in their states of domicile, with the NAIC and, in 

some cases, 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. Such regulations may hamper our ability to meet operating or profitability 
goals, including preventing us from establishing premium rates for some classes of insureds that adequately reflect the level of 
risk assumed for those classes. Many states also regulate investment activities on the basis of quality, distribution and other 
quantitative criteria. States have also enacted legislation, typically based in whole or in part on NAIC model laws, which 

15

regulates insurance holding company systems, including acquisitions, the payment of dividends, the terms of affiliate 
transactions, enterprise risk and solvency management and other related matters.

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

insurance companies.

Insurance companies are also subject to state and federal legislative and regulatory measures and judicial decisions. These 

could include new or updated definitions of risk exposure and limitations on business practices.

Insurance Regulation Concerning Change or Acquisition of Control

The insurance regulatory codes in each of the domiciliary states of our operating subsidiaries contain provisions (subject 

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

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

Insurance Regulation Concerning Cybersecurity

In March 2017, the New York Cybersecurity Regulation took effect for financial institutions, insurers and other 
companies regulated by the NYDFS. The intent of the regulation is to encourage the protection of consumer information, as 
well as the technology systems of NYDFS regulated entities. We are currently compliant with the regulation according to the 
transition periods as defined in the NYDFS Cybersecurity Regulation.

In October 2017, the NAIC adopted the Insurance Data Security Model Law, which created rules for insurers, agents and 

other licensed entities covering data security and investigation and notification of breach. In May 2018, the European Union 
implemented the GDPR, designed to protect data privacy of individuals within the European Union and the EEA. We are 
compliant with the GDPR due to the global nature of our business, including a small amount of international activity in our 
Specialty P&C segment. In addition, managing agents of Lloyd's syndicates are required to ensure that they meet the 
requirements of the GDPR and any local data protection regulation based on territories in which they operate. Syndicate 1729 
and Syndicate 6131, including their managing agent, are compliant with the GDPR.

Each of the domiciliary states of our insurance subsidiaries, excluding Pennsylvania, has enacted data security or data 

privacy acts. Alabama enacted the Alabama Data Breach Notification Act of 2018 effective June 1, 2018, Illinois enacted the 
Illinois’ Personal Information Protection Act effective January 1, 2020, Vermont enacted the Data Breach Notification law 
effective July 1, 2020 and Michigan enacted the Michigan's Data Security Act effective January 20, 2021. Additionally, 
California's Consumer Privacy Act of 2018 was effective January 1, 2020. These state laws require an information security 
program based on an ongoing risk assessment, overseeing third-party service providers, investigating data breaches and 
notifying regulators of a cybersecurity event. The GDPR and the California Consumer Privacy Act of 2018 grant individuals 
the right to request that a company delete or de-identify their personal information. We expect other states, including our 
domiciliary state of Pennsylvania, to either adopt the NAIC's Insurance Data Security Model Law or enact their own data 
security regulations. Moreover, we expect to see privacy laws similar to the California Consumer Privacy Act of 2018 to be 
enacted in other states, including our states of domicile. We do not expect compliance with the various data security or data 
privacy acts to have a material impact on our financial condition or results of operations, as they closely resemble the NAIC 
Model Law, the NYDFS Cybersecurity Regulations and the California Consumer Privacy Act of 2018.

Statutory Accounting and Reporting

Insurance companies are required to file detailed quarterly and annual reports with state insurance regulators in their state 

of domicile and each of the states in which they do business. 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 SAP. Insurance regulators 
periodically examine each insurer’s adherence to SAP, financial condition and compliance with insurance department rules and 
regulations.

16

Regulation of Dividends and Other Payments from Our Operating Subsidiaries

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

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

dividends. Insurance holding company regulations that govern our principal operating subsidiaries deem a dividend as 
extraordinary if the combined dividends and distributions to the parent holding company in any twelve-month period exceed 
prescribed thresholds. Such thresholds are statutorily prescribed by the state of domicile and currently are based on either net 
income for the prior fiscal year (reduced by realized capital gains in certain domiciliary states) or a percentage of unassigned 
surplus at the end of the prior fiscal year, depending upon the wording of the statute.

If insurance regulators determine that payment of a dividend or any other payments within a holding company group, 

(such as payments under a tax-sharing agreement or payments for employee or other services) would, because of the financial 
condition of the paying insurance company or otherwise, be a detriment to such insurance company’s policyholders, the 
regulators may prohibit such payments that would otherwise be permitted.

Risk-Based Capital and Risk Assessment

In order to enhance the regulation of insurer solvency, each state of domicile in accordance with an NAIC-defined 
formula specifies risk-based capital requirements for property and casualty insurance companies. At December 31, 2020, all of 
ProAssurance’s insurance subsidiaries exceeded the minimum required risk-based capital levels.

In late 2010, the NAIC adopted the Model Holding Co. Law. The Model Holding Co. Law, as compared to previous 
NAIC guidance, increases regulatory oversight of and reporting by insurance holding companies, including reporting related to 
non-insurance entities, and requires reporting of risks affecting the holding company group. Additionally, in 2012 the NAIC 
adopted ORSA, which requires insurers to maintain a framework for identifying, assessing, monitoring, managing and reporting 
on the “material and relevant risks” associated with the insurer's (or insurance group's) current and future business plans. ORSA 
requires larger insurers, generally those with annual written premium volume greater than $1 billion as a group or $500 million 
as an individual insurer, to file an internal assessment of solvency with insurance regulators annually beginning in 2015. 
Although no specific capital adequacy standard is currently articulated in ORSA, it is possible that such standard will be 
developed over time. The Model Holding Co. Law and ORSA will be binding only if adopted by state legislatures and/or state 
insurance regulatory authorities and actual regulations adopted by any state may differ from that adopted by the NAIC. As of 
December 31, 2020, all states have adopted the Model Holding Co. Law and 49 states have adopted ORSA. ProAssurance was 
not required to file an internal assessment of solvency under the ORSA criteria for the years ended December 31, 2020 or 2019.

Also, the NAIC subsequently revised the Model Holding Co. Law to include provisions which allow regulatory 
supervision of the holding company group through supervisory colleges and which require reporting of risk and solvency 
assessments for the group. Certain states in which we operate adopted these revisions early, and we began filing our risk and 
solvency assessment in 2014.

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.

Assessment Funds

Admitted insurance companies are required to be members of guaranty associations which administer state guaranty 

funds. To fund the payment of claims (up to prescribed limits) against insurance companies that become insolvent, these 
associations levy assessments on all member insurers in a particular state on the basis of the proportionate share of the 
premiums written by member insurers in the covered lines of business in that state. Maximum assessments permitted by law in 
any one year generally vary between 1% and 2% of annual premiums written by a member in that state, although state 
regulations may permit larger assessments if insolvency losses reach specified levels. Some states permit member insurers to 
recover assessments paid through surcharges on policyholders or through full or partial premium tax offsets, while other states 
permit recovery of assessments through the rate filing process. In recent years, participation in guaranty funds has not had a 
material effect on our results of operations.

17

Certain states in which we write workers’ compensation insurance have established administrative and/or second injury 
funds that levy assessments against insurers that write business in their state. The assessments are generally based on insurer’s 
proportionate share of premiums or losses in a particular state, and the assessment rate can vary from year to year.

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.

Federal Regulation

The Dodd-Frank Act was enacted in July 2010 and established additional regulatory oversight of financial institutions. To 

date, the Dodd-Frank Act has not materially affected our business. However, development of regulations is not complete, and 
there could yet be changes in the regulatory environment that affect the way we conduct our operations or the cost of 
compliance, or both.

One of the federal government bodies created by the Dodd-Frank Act was the FIO which in December 2013 released a 
proposal on insurance modernization and improvement of the system of insurance regulation in the U.S. Although the FIO is 
prohibited from directly regulating the business of insurance, it has authority to represent the U.S. in international insurance 
matters and has limited power to preempt certain types of state insurance laws. The proposal advocates significantly greater 
federal involvement in insurance regulation and identifies necessary reforms by the states to preclude further consideration of 
direct federal regulation. While the proposal does not necessarily imply that the federal government will displace state 
regulation completely, it does recommend more of a hybrid approach to insurance regulation. In response to the FIO proposal, 
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. We cannot 
predict whether the proposals will be adopted or what impact, if any, subsequently enacted laws might have on our business, 
financial condition or results of operations. 

In June 2012, Congress passed the Biggert-Waters Bill, which provided for a five-year renewal of the NFIP and, among 

other things, authorized the Federal Emergency Management Agency to carry out initiatives to determine the capacity of private 
insurers, reinsurers, and financial markets to assume a greater portion of the flood risk exposure in the U.S. and to assess the 
capacity of the private reinsurance market to assume some of the program’s risk. In August 2017, the President of the U.S. 
signed an executive order revoking the establishment of a federal flood risk management standard. In November 2017, the U.S. 
House of Representatives adopted a bill to reauthorize the NFIP for five years and implement several reforms, including 
provisions designed to spur additional private insurer involvement in covering flood risk, but the U.S. Senate has yet to vote on 
the measure. Due to the 2017 hurricane season, Congress adopted a short-term extension to fund the NFIP which has 
subsequently received multiple short-term extensions and currently expires in September 2021. We cannot predict whether the 
proposals will be adopted or extended or what impact, if any, subsequently enacted laws might have on our business, financial 
condition or results of operations.

U.S. Tax Legislation

On December 22, 2017, the President of the U.S. signed the TCJA into law. The TCJA includes significant changes to the 

U.S. corporate income tax system, including a reduction in the federal corporate rate from 35% to 21% beginning after 
December 31, 2017, changes to loss reserve discounting factors, limitations on the deductibility of interest expense and 
executive compensation, and modifications to the taxation of non-U.S. subsidiaries. See further discussion of the impact of the 
TCJA on our results of operations and financial position provided in Item 7, Management's Discussion and Analysis, in the 
Critical Accounting Estimates section under the heading "Taxes" or Note 5 of the Notes to Consolidated Financial Statements.

In response to COVID-19, the CARES Act was signed into law on March 27, 2020 and contains several provisions for 
corporations and eases certain deduction limitations originally imposed by the TCJA. The CARES Act, among other things, 
includes temporary changes regarding the prior and future utilization of NOLs, temporary changes to the prior and future 
limitations on interest deductions, temporary suspension of certain payment requirements for the employer portion of Social 
Security taxes and the creation of certain refundable employee retention credits. See further discussion of the impact of the 
CARES Act on our results of operations and financial position provided in Item 7, Management's Discussion and Analysis, in 
the Critical Accounting Estimates section under the heading "Taxes" or Note 5 of the Notes to Consolidated Financial 
Statements.

Terrorism Risk Insurance Act

TRIA, initially enacted in 2002 and reauthorized in 2007, 2015 and 2019 ensures the availability of insurance coverage 

for certain acts of terrorism, as defined in the legislation. The 2019 reauthorization extended the program through 2027. TRIA 
currently provides that during 2021 and in any year thereafter a loss event must exceed $200 million to trigger coverage and 
that the federal government will reimburse 80% of an insurer’s losses in excess of the insurer’s deductible, up to the maximum 
annual federal liability of $100 billion. TRIA requires that we offer terrorism coverage to our commercial policyholders in our 
workers' compensation line of business, for which we may, when warranted, charge an additional premium. The policyholders 
may or may not accept such coverage.

COVID-19

In response to COVID-19, the federal government and a number of states have introduced or adopted legislation to 
address issues related to the pandemic. The PREP Act was amended on March 27, 2020 to extend liability immunity for 
activities related to medical countermeasures against COVID-19, except for claims involving "willful misconduct" as defined in 
the PREP Act. Certain states have also established immunities for healthcare providers. Depending on the number of states that 
institute such changes and the terms of the changes, as well as the impact of the amendment to the PREP Act and any related 
legal challenges, we may experience a reduction in claims frequency and severity for our healthcare professional liability book 
of business.

With respect to workers' compensation coverages, some states have enacted legislation changes designed to effectively 
expand coverage by establishing a presumption of compensability for certain types of workers. Other states are considering 
similar measures. Depending on the number of states that institute such changes and the terms of the changes, we may 
experience increases in claims frequency and severity for our workers’ compensation book of business, which could have an 
effect on our financial condition, results of operations and cash flows.

Furthermore, we are closely monitoring the impact of potential legislation or court decisions that could retroactively 
require insurers to extend certain insurance to cover COVID-19 claims, even if the original contract excluded the cover of 
communicable diseases as is typical in certain policies; however, to date, legislative attempts have been unsuccessful. If 
successful, these actions could result in an increase in claim frequency and severity due to an unintended increase in exposure 
for Syndicate 1729 and 6131 which could have an effect on our financial condition, results of operations and cash flows given 
our participation in those Syndicates.

International

Cayman Islands

Our SPC business operates through our subsidiaries, Inova Re and Eastern Re, which are organized and licensed as 

Cayman Islands unrestricted Class B insurance companies. Inova Re and Eastern Re are subject to regulation by the CIMA. 
Applicable laws and regulations govern the types of policies that Inova Re and Eastern Re can insure or reinsure, the amount of 
capital they must maintain and the way it can be invested, and the payment of dividends without approval by the CIMA. Inova 
Re and Eastern Re are required to maintain minimum capital of approximately $200,000 and must receive approval from the 
CIMA before they can pay any dividends.

United Kingdom

Syndicate 1729 and Syndicate 6131 are regulated in the U.K. by the Prudential Regulation Authority and the Financial 
Conduct Authority. All Lloyd's Syndicates must also comply with the bylaws and regulations established by the Council of 
Lloyd's including submission and approval of an annual business plan and maintenance of stipulated capital levels. Also, the 
Council of Lloyd's may call or assess a percentage of a member's underwriting capacity (currently a maximum of 3%) as a 
contribution to Lloyd's Central Fund, which, similar to state guaranty funds in the U.S., meets policyholder obligations if a 
Lloyd's member is otherwise unable to do so.

Effective January 1, 2016, the European Union's executive body, the European Commission, implemented capital 

adequacy and risk management regulations called Solvency II that applies to businesses within the European Union. Both 
Syndicate 1729 and Syndicate 6131 follow the Solvency II compliance guidelines set out by the Council of Lloyd's.

On January 31, 2020, the U.K. withdrew from the European Union, commonly referred to as "Brexit", and entered a 
transition period which lasted until December 31, 2020. Following the transition period, a new trade deal went into effect 
January 1, 2021 between the U.K. and European Union. In November 2018, Lloyd's opened a new European insurance 
company in Brussels in order to maintain access to European Union business. Lloyd's Brussels is Lloyd's first Europe wide 
operation and brings Lloyd's expertise closer to its customers and partners in Europe. As of December 31, 2020, Lloyd's 

19

Brussels has moved all legacy EEA business to Brussels via a Part VII portfolio transfer, which allowed insurers and reinsurers 
to transfer portfolios of insurance business from one legal entity to another.

Human Capital Resources

We are a people business and we are committed to our employees as well as those individuals whom our employees serve. 

We aim to attract, develop, and retain a diverse group of employees who embody our Mission, Vision and Values. 

We are committed to providing a safe and healthy working environment where all employees are treated with dignity and 

respect, allowing them to do their best work. Further, we seek to provide equal opportunities while fostering a diverse and 
inclusive workplace that promotes employee engagement. To ensure our workforce is comprised of a diverse group of highly-
qualified individuals, we are committed to advertising job openings and sourcing candidates through broad-reaching techniques. 
We are committed to a strategy of workforce diversity and inclusion at all levels of the Company, starting with our Board and 
extending through all levels within our organization. Further, we seek to provide a fulfilling work experience through the 
creation of well-documented career paths and opportunities for advancement, robust training and development programs and 
the management of transparent salary administration practices. Our competitive pay and benefit programs are designed to 
reward, support and retain our employees. 

We are committed to facilitating and fostering employee engagement. To support those objectives, we measure employee 
engagement and satisfaction by conducting “Pulse” surveys that gain real-time feedback from our employees on key issues. The 
results are shared with all employees and the data is used to steer our continuous improvement efforts. We regularly monitor 
and evaluate turnover metrics to ensure we are responsive to the evolving, competitive market for top talent. 

In the event of downsizing and lay-offs are necessary, we provide favorable severance packages that include support of re-

employment. During 2020, in response to the external environment and to improve our future competitive position, we 
restructured our Specialty P&C and Workers' Compensation Insurance segments to better serve our policyholders and agency 
partners. As a result, we transformed our workforce through a combination of early retirement, job eliminations, reassignments 
and promotions that spanned our entire organization.

Some examples of key programs and initiatives that are focused on attracting, developing and retaining our diverse 

workforce include:

•

•

Diversity, Equity and Inclusion - To advance our commitment to fostering a diverse, inclusive and equitable
workplace, in 2020 we engaged an external professional services partner to help guide the identification of short and
long-term strategies. One specific strategy is the formation of a Diversity, Equity and Inclusion Council comprised of
employees from across the organization who serve as an ongoing resource to the organization in identifying objectives
and tracking achievements. We continue to enhance our professional development and training programs to further
build knowledge, understanding and skill in support of full cultural competency. We anticipate the development and
training aspects of this initiative to be achieved within the first half of 2021.
Employee and Leadership Development - We invest in training and development programs that support our Mission,
Vision and Values, encourage continuous learning, equip employees for advancement and encourage a long-term
partnership with the Company. We provide career paths for employees to continue to advance their technical skills. To
grow the skills of our current managers and plan for future succession needs, we provide a tiered leadership
development program, Leadership That Works that includes both in-person group and self-led content.

Employee Health and Welfare - We recognize the importance of a comprehensive benefits strategy to support the
unique needs of all employees. We made several key changes in 2020 that address the expanding needs of our
employees as a result of the pandemic. We adopted all guidelines of the CARES Act including the retirement plan
withdrawal and loan provisions. In addition, we implemented the applicable guidelines of the Families First
Coronavirus Response Act. We expanded our virtual health management benefits to include mental well-being and
enhanced our accident and critical illness program. In addition, we implemented a new benefit offering which includes
access to a service provider that offers assistance and expertise in navigating federal and state programs including
social security, disability, unemployment and retirement.

COVID-19 Response - At the onset of the pandemic, we responded by transitioning the majority of our employees to
work remotely. As it was safe to do so, we began to allow employees to voluntarily return to the office and
implemented mandatory employee training, social distancing, handwashing, daily health questionnaires and other
safety measures. We continue to regularly monitor the situation at the highest level of the organization, implementing
changes to strategy as appropriate. Returning to the office will continue to be 100% voluntary for the foreseeable
future.

ProAssurance Corporation and our subsidiaries are equal opportunity employers and we do not discriminate either directly 
or indirectly against employees or prospective employees on the basis of race, color, religion, sex, sexual preference/orientation, 
citizenship, marital status, veteran status, national origin, age or disability, or any other attribute protected by applicable law or 
regulation. At December 31, 2020, we had 827 employees, none of whom were represented by a labor union. We consider our 
employee relations to be good.

Enterprise Risk Management

As a property and casualty insurance provider, we are exposed to many risks stemming from both our insurance 

operations and the environments in which we operate. Since certain risks can be correlated with other risks, an event or a series 
of events can impact multiple areas of the Company simultaneously and have a material effect on the Company's results of 
operations, financial position and/or liquidity. In response to these exposures we have implemented an ERM program. Our 
ERM program consists of numerous processes and controls that have been designed by our senior management with oversight 
by our Board and implemented across our organization. We utilize our ERM program to identify potential risks from all aspects 
of our operations and to evaluate these risks in a manner that is both prudent and balanced. Our primary objective is to develop 
a risk appetite that creates and preserves value for all of our stakeholders.

ITEM 1A. RISK FACTORS.

There are a number of factors, many beyond our control, which may cause results to differ significantly from our 
expectations. Through our ERM program, as previously discussed, we have attempted to identify and understand the nature, 
caliber and sensitivity of material foreseeable risks, mitigate or avoid those risks and determine a course of action necessary to 
address such risks. These risk factors fall under the following four categories: Insurance, Financial, Operational and General. 
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

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 in a fragmented market comprised of 

many insurers, ranging from smaller single state monoline insurers who have an extensive knowledge of local markets to large 
national insurers who offer multiple product lines and whose financial strength and resources may be greater than ours. In many 
instances, coverage we offer is also available through mutual entities whose ROE objectives may be lower than ours. Also, 
there are many opportunities for self-insurance and for participation in an alternative risk transfer mechanism, such as a captive 
insurer or a risk retention group.

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. Actions of competitors could adversely affect our ability to attract 
and retain business at current premium levels, impact our market share and reduce the profits that would otherwise arise from 
operations.

The cyclicality in the property and casualty insurance industry could have a material adverse effect on our ability to improve or 
maintain underwriting profits or to grow or maintain premium volume. 

The insurance and reinsurance markets have historically been cyclical, characterized by extended periods of intense price 

competition and other periods of reduced competition. The professional liability area has been particularly affected by these 
cycles. Underwriting cycles are generally driven by an excess of capacity available and actively pursuing business that is 
deemed profitable. This action drives pricing down. Since the professional liability industry has a long development period, 
prices typically fall too far resulting in poor underwriting results for a period of time. The reaction is then a withdrawal of 
capacity, reduced availability of coverage offerings and price increases. In past cycles, these actions improve profitability over a 
few years inviting new capital into the market again which causes the cycle to repeat. Events other than price can also have a 
material effect on the duration and depth of the underwriting cycles, such as severity spikes, tort reforms, abrupt frequency 
changes or reinsurance availability. Changes in the frequency and severity of losses may affect the cycles of the insurance and 
reinsurance markets significantly. During "soft markets" where price competition is high and underwriting profits are poor, 
growth and retention of business become challenging which may result in reduced premium volume. During the initial stages of 
"hard markets", premium volumes rise for existing business and retention levels fall. As more carriers enter this action phase, 

21

underwriting profits begin to improve, although their achievement may take several years to materialize. As the cycle 
progresses, opportunities may then be presented to grow profitably at the higher premium levels.

The Company's results of operations could be adversely impacted by catastrophes, both natural and man-made, pandemics,
severe weather conditions, climate change or closely related series of events.

Catastrophes can be caused by unpredictable natural events such as hurricanes, windstorms, severe storms, tornadoes, 
floods, hailstorms, severe winter weather, earthquakes, explosions and fire, and by other natural and man-made events, such as 
terrorist attacks, civil and political unrest, as well as pandemics and other similar outbreaks in many parts of the world, 
including the recent outbreak of a coronavirus referred to as COVID-19. Insurance companies are not permitted to reserve for a 
catastrophe until it has occurred. Although we purchase reinsurance protection for risks we believe bear a significant level of 
catastrophe exposure, actual losses resulting from a catastrophic event or events may exceed our reinsurance protection. 
Furthermore, for significant catastrophic exposure, the inability or unwillingness of the reinsurer to make timely payments 
under the terms of the reinsurance agreement could impact our liquidity. These events may have a material adverse effect on 
our workforce and business operations as well as the workforce and operations of our insureds and independent agents. Some of 
the assets in our investment portfolio may be adversely affected by declines in the equity markets, changes in interest rates, 
reduced liquidity and economic activity caused by large-scale catastrophes, pandemics, terrorist attacks or similar events which 
could have a material adverse effect on our financial position, results of operations and liquidity.

 The incidence, frequency and severity of catastrophes are inherently unpredictable. While we use historical data and 
modeling tools to assess our potential exposure to catastrophic losses under various conditions and probability scenarios, such 
assessments do not necessarily accurately predict future losses or accurately measure our potential exposure. The extent of 
losses from a catastrophe is a function of both the total amount of insured exposure in the area affected by the event and the 
severity of the event.

Our loss exposure for a terrorist act meeting the TRIA definition is mitigated by our coverage provided by this program as 

described in Part I under the heading "Insurance Regulatory Matters." Congress has the ability to alter or repeal the provisions 
of TRIA at its discretion, and if altered or repealed, our exposure could increase and result in premium increases for those types 
of coverages. Workers' compensation coverages cannot exclude damages related to an act of terrorism, and if TRIA were 
repealed or the benefits were substantially reduced, this might affect our ability to offer these coverages at a reasonable rate. In 
addition, the program currently expires at the end of 2027, and the failure to extend the program could adversely affect our 
business through increased exposure to a catastrophic level of terrorism losses.

Our results of operations and financial condition may be affected if actual insured losses differ from our loss reserves or if 
actual amounts recoverable under reinsurance agreements differ from our estimated recoverables.

We establish reserves as balance sheet liabilities, representing our estimates of amounts needed to resolve reported and 
unreported losses and pay related loss adjustment expenses. Our largest liability is our reserve for losses and loss adjustment 
expenses. Due to the size of our reserve for losses 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 may elapse between the occurrence of an 
insured loss, the reporting of the loss by the insured and payment of that loss. Ultimate loss costs, even for claims with similar 
characteristics, can vary significantly depending upon many factors including but not limited to the nature of the claim, 
including whether the claim is an individual or a mass tort claim, the personal situation of the claimant or the claimant’s family, 
the outcome of jury trials, the legislative and judicial climate where the insured event occurred, general economic conditions 
and, for claims involving bodily injury, the trend of healthcare costs. Consequently, the loss cost estimation process requires 
actuarial skill and the application of judgment and such estimates require periodic revision. As part of the reserving process, we 
review the known facts surrounding reported claims as well as historical claims data and consider the impact of various factors 
such as:

•
•
•
•
•
•
•

for reported claims, the nature of the claim and the jurisdiction in which the claim occurred;
trends in paid and incurred loss development;
trends in claim frequency and severity;
emerging economic and social trends;
trends in healthcare costs for claims involving bodily injury;
inflation and levels of employment; and
changes in the regulatory, legal and political environment.

This process assumes that past experience, adjusted for the effects of current developments and anticipated trends, is an

appropriate, but not necessarily accurate, basis for predicting future events. There is no precise method for evaluating the 
impact of any specific factor on the adequacy of reserves, and actual results are likely to differ from original estimates. We 
evaluate our reserves each period and increase or decrease reserves as necessary based on our estimate of future claims 

22

payments. An increase to reserves has a negative effect on our results of operations in the period of increase; a reduction to 
reserves has a positive effect on our results of operations in the period of reduction.

Our loss reserves also may be affected by court decisions that expand liability of our policies after they have been issued. 

As previously discussed under the heading "Insurance Regulatory Matters," we are closely monitoring the impact of potential 
legislation or court decisions that could effectively expand workers' compensation coverage by establishing a presumption of 
compensability for certain types of workers which could result in an increase in claim frequency and severity for our workers' 
compensation book of business. As it relates to our exposures through our participation in Syndicate 1729 and Syndicate 6131, 
we are also monitoring the impact of potential legislation or court decisions that could retroactively require insurers to extend 
certain insurance to cover COVID-19 claims, even if the original contract excluded the cover of communicable diseases, which 
could result in an increase in claim frequency and severity for Syndicate 1729 and Syndicate 6131 due to an unintended 
increase in exposure. These attempts to date, however, have been unsuccessful. In addition, extension of statutes of limitations 
in some states could result in assertion of covered claims that otherwise would have been time-barred. We cannot predict the 
occurrence of such claim, the magnitude of any associated liability if such claims occur, or the effect of such claims on our 
financial results. Further, a significant jury award or series of awards against one or more of our insureds could require us to 
pay large sums of money in excess of our reserved amounts. Due to uncertainties inherent in the jury system, any case that is 
litigated to a jury verdict has the potential to incur a loss that has a material adverse effect on our results of operations.

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

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

We use analytical models to assist our decision-making in key areas such as pricing and reserving and may be adversely 
affected if actual results differ materially from the model outputs and related analyses.

We use various modeling techniques and data analytics to analyze and estimate exposures, loss trends and other risks 
associated with our assets and liabilities. This includes both proprietary and third party modeled outputs and related analyses to 
assist us in decision-making (e.g., underwriting, pricing, claims, reserving, reinsurance and catastrophe risk) and to maintain a 
competitive advantage. Since there is no industry standard for assumptions and preparation of insured data for use in these 
models, our modeled losses may not be comparable to estimates made by other companies. The modeled outputs and related 
analyses from both proprietary and third parties are subject to various assumptions, uncertainties, model design errors and the 
inherent limitations of any statistical analysis, including those arising from the use of historical internal and industry data and 
assumptions. Changes in the social, judicial or economic environments in which we operate may make modeled outcomes less 
reliable or produce new, non-modeled risks. In addition, the effectiveness of any model can be degraded by operational risks 
including, but not limited to, the improper use of the model. Consequently, actual results may differ materially from our 
modeled results. If actual losses exceed assumptions that were made when our products were priced or our models fail to 
appropriately estimate the risks we are exposed to, our business, financial condition, results of operations or liquidity may be 
adversely affected. Furthermore, our results may be adversely affected if actual losses exceed assumptions that were made when 
pricing products that also include features such as an option to purchase extended reporting endorsement or "tail" coverage, 
which are offered at rates that are tied to expiring premiums charged. The profitability and financial condition of the Company 
substantially depends on the extent to which our actual experience is consistent with assumptions we use in our models and 
ultimate model outputs.

We are exposed to and may face adverse developments involving mass tort claims arising from coverages provided to our 
insureds.

Establishing reserves for mass tort claims is subject to uncertainties due to many factors, including expanded theories of 

liability, geographical location and jurisdiction of the lawsuits. Moreover, it is difficult to estimate our ultimate liability for such 
claims due to evolving judicial interpretations of various tort theories of liability and defense theories, such as federal 
preemption and joint and several liability, as well as the application of insurance coverage to these claims.

If market conditions cause reinsurance to be more costly or unavailable, we may be required to bear increased risk 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 subsidiaries. Market conditions beyond our control determine the availability and cost of the 

23

reinsurance. We may be unable to maintain current reinsurance coverage or to obtain other reinsurance coverage in adequate 
amounts and at favorable rates. If we are unable to renew our expiring coverage or to obtain new reinsurance coverage, either 
our net exposure to risk would increase or, if we are unwilling to bear an increase in net risk exposures, we would need to 
reduce the amount of our underwritten risk.

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

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

If we are unable to maintain favorable financial strength ratings, it may be more difficult for us to write new business or renew 
our existing business.

Independent rating agencies assess and rate the claims-paying ability and the financial strength of insurers based upon 
criteria established by the agencies. Periodically the rating agencies evaluate us to confirm that we continue to meet the criteria 
of previously assigned ratings. The financial strength ratings assigned by rating agencies to insurance companies represent 
independent opinions of financial strength and ability to meet policyholder and debt obligations and are not directed toward the 
protection of equity investors.

Our principal operating subsidiaries hold favorable claims paying ratings with A.M. Best, Fitch and Moody’s. Claims-

paying ratings are used by agents, brokers and customers as an important means of assessing the financial strength and quality 
of insurers. If our financial position deteriorates or the rating agencies significantly change the rating criteria that are used to 
determine ratings, we may not maintain our favorable financial strength ratings from the rating agencies. A downgrade or 
involuntary withdrawal of any such rating could limit or prevent us from writing desirable business.

The following table presents the claims paying ratings of our core insurance subsidiaries as of February 19, 2021.

In addition to the evaluation of our claims paying ability, four rating agencies (A.M. Best, S&P, Fitch and Moody’s) 

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

Our business could be adversely affected by the loss or consolidation of independent agents, agencies, brokers or brokerage 
firms.

We heavily depend on the services of independent agents and brokers in the marketing of our insurance products. We face 

competition from other insurance companies for their services and allegiance. These agents and brokers may choose to direct 
business to competing insurance companies.

As a member of the Lloyd's market and a capital provider to Lloyd's Syndicate 1729 and Syndicate 6131 we are subject to 
certain risks which could affect us.

As a participant in Lloyd's Syndicates, we are subject to certain risks and uncertainties, including the following:

•
•
•

•
•
•

•

•

reliance on insurance and reinsurance brokers and distribution channels to distribute and market products;
obligation to pay levies to Lloyd's;
obligations to maintain funds to support underwriting activities and risk-based capital requirements that are
assessed periodically by Lloyd's and subject to variation;
ability to maintain liquidity to fund claims payments, when due;
ability to obtain reinsurance and retrocessional coverage to protect against adverse loss activity;
reliance on ongoing approvals from Lloyd's and various regulators to conduct business, including a requirement
that Annual Business Plans be approved by Lloyd's before the start of underwriting for each account year;
financial strength ratings are derived from the rating assigned to Lloyd's, although they have limited ability to
directly affect the overall Lloyd's rating; and
reliance on Lloyd's trading licenses in order to underwrite business outside the U.K.

Financial

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

We transfer part of our risks to reinsurance companies in exchange for part of the premium we receive in connection with 
the risk. Although our reinsurance agreements make the reinsurer liable to us to the extent the risk is transferred, our liability to 
our policyholders remains our responsibility. Reinsurers may periodically dispute our demand for reimbursement from them 
based upon their interpretation of the terms of our agreements or may fail to pay us for financial or other reasons. If reinsurers 
refuse or fail to pay us or fail to pay on a timely basis, our financial results and/or cash flows could be adversely affected and 
could have a material effect on our results of operations in the period in which uncollectible amounts are identified.

 At December 31, 2020 our receivable from reinsurers on unpaid losses and loss adjustment expenses was $385 million, 

our receivable from reinsurers on paid losses and loss adjustment expenses was $14 million and our expected credit losses 
associated with our reinsurance receivables (related to both paid and unpaid losses) were nominal in amount. As of 
December 31, 2020, no reinsurer, on an individual basis, had an estimated net amount due which exceeded $51 million.

The impact of the COVID-19 pandemic and related general economic conditions could have a material adverse effect on our 
results of operations, financial position or liquidity.

The continuing global COVID-19 pandemic has impacted the global economy, financial markets and our results of 
operations. Because of the size and breadth of this pandemic, all of the direct and indirect consequences of COVID-19 are not 
yet known and may not emerge for years. Impacts to our results of operations could be widespread and material, including but 
not limited to, the following:

•

•
•

•
•
•
•

•
•
•
•

continued volatility and further disruption in global financial markets that could materially affect our investment
portfolio valuations and returns;
declining interest rates which could reduce future investment results;
negative impact on premium volume due to reduced demand and decreased insured exposures due to the impact of
COVID-19 on general economic activity, especially for lines of business that are sensitive to rates of economic growth
and those that are impacted by audit premium adjustments;
negative impact on expense ratios due to reduced premium volume;
increases in frequency and/or severity of compensable claims, losses litigation and related expenses;
losses from COVID-19 related claims could be greater than our reserves for those losses;
government mandates and/or legislative changes in response to COVID-19, including, but not limited to: actions
prohibiting an insurance company from canceling insurance policies in accordance with policy terms; requiring an
insurance company to cover losses when its policies specifically excluded coverage or did not provide coverage;
preventing an insurance company from filing for a rate increase; ordering an insurance company to provide premium
refunds; granting premium grace periods and presumed COVID-19 compensability for all or certain occupational
groups;
increased credit risk;
reduced cash flows from premium credits and from our policyholders delaying premium payments;
increased cybersecurity risk as criminals seek new ways to target shifting business models; and
business disruption to independent insurance agents and brokers.

25

We are taking precautions to protect the safety and well-being of our employees while providing uninterrupted service to 
our policyholders and claimants. It is not possible at this time to estimate the impact that COVID-19 could have on our results 
of operations and financial condition, as the impact will depend on future developments, which are highly uncertain and cannot 
be predicted. Further, to the extent the COVID-19 pandemic adversely affects our business and financial results, it may also 
have the effect of heightening many of the other risks described herein.

If our businesses do not perform well, we may be required to recognize an impairment of our goodwill or intangible assets, 
which could have a material adverse effect on our results of operations and financial condition.

We review our definite–lived intangible assets for impairment when events or changes in circumstances indicate that the 
carrying value may not be recoverable from estimated future cash flows. We test goodwill and intangible assets with indefinite 
lives for impairment on an annual basis or upon the occurrence of certain triggering events or substantive changes in 
circumstances that indicate the asset may be impaired. If we determine that such goodwill or intangible assets are impaired, we 
would be required to write down the goodwill or the intangible asset by the amount of the impairment, with a corresponding 
charge to net income (loss). Such write downs could have a material adverse effect on our results of operations or financial 
position.

Our investment results may be impacted by changes in interest rates, U.S. monetary and fiscal policies as well as broader 
economic conditions.

Changes in interest rates and U.S. fiscal, monetary and trade policies as well as broader economic conditions could have a 

material adverse effect on our investment results. Fluctuations in the value of our investment portfolio can occur as a result of 
these changes. Our investment portfolio is primarily comprised of interest-earning assets, marked to fair value each period. 
Thus, prevailing economic conditions, particularly changes in market interest rates, may significantly affect our results of 
operations. Significant movements in interest rates potentially expose us to lower yields or lower asset values. Changes in 
market interest rate levels generally affect our net income (loss) 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.

Our investments are subject to credit, prepayment and other risks.

A significant portion of our total assets ($3.4 billion or 73%) at December 31, 2020 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 impairment of our securities, which could affect our financial condition, results of operations or cash 
flows.

At December 31, 2020 approximately 20% of our investment portfolio was invested in mortgage and asset-backed 
securities. We utilize ratings determined by NRSROs (Moody’s, Standard & Poor’s and Fitch) as an element of our evaluation 
of the creditworthiness 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.

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

At December 31, 2020 the fair value of our state/municipal portfolio was $332.9 million (amortized cost basis of $316.0 
million). While our state/municipal portfolio had a high credit rating (AA on average), which indicates a strong ability to pay, 
there is no assurance that there will not be a credit related event which would cause fair values to decline. An economic 
downturn could lessen tax receipts and other revenues in many states and their municipalities.

Our tax credit partnership interests are subject to risks related to the potential forfeiture of the tax credits and all or a 
portion of the previously claimed tax credits. Loss of all or a portion of the tax credits might occur if the property owner fails to 
meet the specified requirements of planning and constructing or, in the case of the qualified affordable housing project tax 
credits, fails to operate the property as required or below expected capacity. Changes to tax rates may change the expected 
duration of the utilization of tax credits. While this would not impact the amount of tax credits we receive, a change in duration 
could be impactful from an economic perspective due to the time value of money. Additionally, if tax rates were to decrease the 

26

value of losses embedded in our tax credits could decrease due to a lower deduction value, which would reduce the carrying 
value of the partnership interests and could result in an impairment. At December 31, 2020 the carrying value of our tax credit 
partnership interests was approximately $27.7 million.

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.

At December 31, 2020 and in accordance with applicable GAAP, we valued 96% of our investments at fair value and the 
remaining 4% at cost, equity, or cash surrender value. See Notes 1, 2 and 3 of the Notes to Consolidated Financial Statements 
for additional information.

We determine the fair value of our investments using quoted exchange or over-the-counter prices, when available. At 
December 31, 2020, we valued approximately 12% of our investments in this manner. When exchange or over-the-counter 
quotes are not available, we estimate fair values based on broker dealer quotes and various other valuation methodologies, 
which may require us to choose among various input assumptions and utilize judgment. At December 31, 2020, approximately 
77% of our investments were valued in this manner. When markets exhibit significant 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 that would be received upon disposition of the security. At 
December 31, 2020, approximately 7% of our investments are investment funds which measure fund assets at fair value on a 
recurring basis and provide us with a NAV for our interest. As a practical expedient, we consider the NAV provided to 
approximate the fair value of the interest. NAV is provided by the asset managers, and in some cases, estimates are used for 
valuation and are subject to variations depending on those estimates. Our funds valued at NAV have various redemption 
requirements and lock-up provisions (see Note 2 of the Notes to Consolidated Financial Statements for further information).

Our ability to issue additional debt or letters of credit or other types of indebtedness on terms consistent with current debt is 
subject to market conditions, economic conditions at the time of proposed issuance, results of ratings reviews and the inclusion 
in certain bond indices of past and future issues. Also, certain of our current debt agreements and loans include financial 
covenants, and the issuance of debt by one of our insurance subsidiaries requires regulatory approval, both of which may limit 
or prohibit the issuance of additional debt.

Our Revolving Credit Agreement, which expires in November 2024, permits borrowings of up $300 million. The 
agreement requires that our consolidated debt to capital ratio (0.17 to 1.0 at December 31, 2020) be 0.35 to 1.0 or less and that 
we maintain a minimum net worth of $1 billion which represented 65% of consolidated shareholders' equity, excluding AOCI, 
determined as of June 30, 2019.

During 2017, two of our insurance subsidiaries entered into ten-year mortgage loans. These mortgage loans require each 

of the subsidiaries to have a leverage ratio of consolidated funded debt to consolidated total capitalization (principally, SAP 
consolidated net worth plus consolidated funded debt) be 0.35 to 1.0 or less. Furthermore, our insurance subsidiaries must 
obtain regulatory approval before incurring additional debt.

During 2013, we issued $250 million of unsecured Senior Notes Payable due in 2023 at a 5.3% interest rate. There is no 
guarantee that additional debt could be issued on similar terms in the future as rates available to us may change due to changes 
in the economic climate, or shifts in the yield curve may occur, or an increase in our level of debt may result in rating agencies 
lowering our debt rating.

The interest rates on our Mortgage Loans and Revolving Credit Agreement are priced using a spread over LIBOR, which may 
be phased out in the future.

LIBOR is the basic rate of interest used in lending between banks on the London interbank market and is widely used as a 
reference for setting interest rates on loans globally. The terms of certain of our debt agreements include interest rates which are 
calculated based on LIBOR.

On July 27, 2017, the United Kingdom’s Financial Conduct Authority, which regulates LIBOR, announced that it intends 
to phase out LIBOR by the end of 2021. It is unclear if at that time whether or not LIBOR will cease to exist or if new methods 
of calculating LIBOR will be established such that it continues to exist after 2021. On November 30, 2020, the U.S. Federal 
Reserve announced that it intends for all contracts written with LIBOR benchmarks to end on or before June 30, 2023. The U.S. 
Federal Reserve, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. 
financial institutions, announced the replacement of U.S. dollar LIBOR with a new index calculated by short-term repurchase 
agreements, backed by U.S. Treasury securities called the Secured Overnight Financing Rate (“SOFR”). The first publication of 
SOFR was released in April 2018 and was subsequently codified by the FASB in October 2018. The updated codification added 
the overnight index swap rate ("OIS") based on the SOFR to the list of U.S. benchmark interest rates that are eligible to be 
hedged. During 2020, the FASB issued guidance intended to assist stakeholders during the market-wide reference rate transition 
period and is effective for a limited period between March 12, 2020 and December 31, 2022. The guidance provides optional 

27

expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference LIBOR 
or another reference rate that is expected to be discontinued because of reference rate reform.

We have exposure to LIBOR-based financial instruments through our variable rate Mortgage Loans and Revolving Credit 
Agreement; however, these agreements include provisions for an alternative benchmark rate if LIBOR ceases to exist which do 
not materially change our liability exposure. Additionally, we have exposure to LIBOR in our available-for-sale fixed 
maturities portfolio which represented approximately 6% of our total investments, or $191 million, as of December 31, 2020; 
34% of these investments with exposure to LIBOR were issued during 2020 or 2019 and include provisions for an alternative 
benchmark rate. Optional expedients for contract modifications include a prospective adjustment that does not require contract 
remeasurement or reassessment of a previous accounting determination; therefore, the modified contract is accounted for as a 
continuation of the existing contract. At this time, we cannot predict the overall effect of the modification or discontinuation of 
LIBOR or the establishment of alternative benchmark rates.

Resolution of uncertain tax matters and changes in tax laws or taxing authority interpretations of tax laws could result in actual 
tax benefits or deductions that are different than we have estimated, both with regard to amounts recognized and the timing of 
recognition. Such differences could affect our results of operations or cash flows.

Our provision for income taxes, our recorded tax liabilities and net deferred tax assets, including any valuation 

allowances, are recorded based on estimates. These estimates require us to make significant judgments regarding a number of 
factors, including, among others, the applicability of various federal and state laws, the interpretations given to those tax laws 
by taxing authorities, courts and the Company, the timing of future income and deductions, and our expected levels and sources 
of future taxable income. We believe our tax positions are supportable under current tax laws and that our estimates are 
prepared in accordance with GAAP. Additionally, from time to time, due to changes in economic and/or political conditions, 
there are changes in tax laws and interpretations of tax laws which could significantly change our estimates of the amount of tax 
benefits or deductions expected to be available to us in future periods. Specifically, changes in federal tax law as a result of the 
TCJA included a reduction in the U.S. corporate income tax rate, changes to the cost of cross border reinsurance, changes to the 
overall tax base and a limitation on the deductibility of certain executive compensation in future periods. Changes to our prior 
estimates in these cases 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 flows. As the Company has reinsurance operations domiciled in the Cayman 
Islands, changes in the tax laws of the Cayman Islands as well as the change in U.S. federal tax law as a result of the TCJA 
regarding outbound cross border affiliate reinsurance could result in the loss of profitability of that business.

We are subject to U.S. federal and various state income taxes as well as U.K. related taxes. We are periodically under 
examination by federal, state and local authorities regarding income tax matters, and our tax positions could be successfully 
challenged; the costs of defending our tax positions could be considerable. Our estimate of our potential liability for known 
uncertain tax positions is reflected in our financial statements. As of December 31, 2020 we had a net deferred tax asset of 
approximately $57.1 million and a net federal income tax receivable of approximately $18.9 million, which included a liability 
for unrecognized current tax benefits of $5.2 million.

Operational

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

The U.S. federal government generally has not directly regulated the insurance industry except for certain areas of the 
market, such as insurance for flood, nuclear and terrorism risks. However, the federal government has undertaken initiatives or 
considered legislation in several areas that may affect the insurance industry. The Dodd-Frank Act was enacted in July 2010 
and established additional regulatory oversight of financial institutions (see previous discussion under the heading "Insurance 
Regulatory Matters"). Our business could be affected by changes to the U.S. system of insurance regulation including 
legislative or regulatory requirements imposed by or promulgated in connection with the Dodd-Frank Act. 

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 protect the rights of a defendant 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 previously enacted tort reform 
legislation in an effort to reduce escalating loss trends.

Challenges to tort reform have been undertaken in most states where tort reforms have been enacted, and in some states 

the reforms have been fully or partially overturned. Additional challenges to tort reform may be undertaken. We cannot predict 
with any certainty how 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 

28

ultimately upheld by the courts. Furthermore, 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 insurance entities that could remove our potential insureds from the private insurance market.

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

Our performance is dependent on the business, economic, regulatory and legislative conditions of states where we have a 
significant amount of business.

Our top five states, Pennsylvania, Alabama, Indiana, Texas and Michigan, represented 39% of our direct premiums 
written for the year ended December 31, 2020. Moreover, on a combined basis, Pennsylvania, Alabama and Indiana accounted 
for 28% of our direct premiums written for each of the years ended December 31, 2020, 2019 and 2018. 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.

From time to time we may identify opportunities for growth through acquisitions. However, approval of acquisitions may not be 
granted or conditions of approval may adversely alter the expected value and benefits of the acquisition. In addition, expected 
benefits from acquisitions may not be achieved or may be delayed longer than expected.

Growth through the acquisition of other companies or books of business is opportunistic and sporadic. If we are able to 

identify a target for acquisition, state insurance regulation concerning change or acquisition of control could delay or prevent us 
from completing the acquisition. State insurance regulatory codes provide that the acquisition of “control” of a domestic insurer 
or of any person that directly or indirectly controls a domestic insurer cannot be consummated without the prior approval of the 
domiciliary insurance regulator. There is no assurance that we will receive such approval from the respective insurance 
regulator or that such approvals will not be conditioned in a manner that materially and adversely affects the aggregate 
economic value and business benefits expected to be obtained and cause us to not complete the acquisition.

The Company performs thorough due diligence before agreeing to a merger or acquisition; however, there is no guarantee 
that the procedures we perform will adequately identify all potential weaknesses or liabilities of the target company or potential 
risks to the consolidated entity.

There is also no guarantee that businesses acquired in the future will be successfully integrated. Ineffective integration of 
our businesses and processes may result in substantial costs or delays and adversely affect our ability to compete. The process 
of integrating an acquired company or business can be complex and costly and may create unforeseen operating difficulties 
including the ineffective integration of underwriting, risk management, claims handling, finance, information technology and 
actuarial practices and the design and operation of internal controls over financial reporting. Difficulties integrating an acquired 
business may also result in the acquired business performing differently than we expected including the loss of customers or in 
our failure to realize anticipated growth or expense-related efficiencies. We could be adversely affected by the acquisition due 
to unanticipated performance issues and additional expense, unforeseen or adverse changes in liabilities, including liabilities 
arising from events prior to the acquisition or that were unknown to us at the time of the acquisition, transaction-related 
charges, diversion of management time and resources to integration challenges, loss of key employees, regulatory requirements, 
exposure to tax liabilities, exposure to pension liabilities, amortization of expenses related to intangibles, and charges for 
impairment of assets or goodwill.

Furthermore, claims may be asserted by either the policyholders or shareholders of any acquired entity related to 

payments or other issues associated with the acquisition and merger into the consolidated entity. Such claims may prove costly 
or difficult to resolve or may have unanticipated consequences.

There are numerous risks and uncertainties around the Company's planned acquisition of NORCAL.

On February 20, 2020 we entered into a definitive agreement to acquire NORCAL, an underwriter of medical professional 

liability insurance, subject to the demutualization of NORCAL Mutual, NORCAL's ultimate controlling party. See Note 9 of 
the Notes to Consolidated Financial Statements for further information. If consummated, the transaction will provide strategic 
and financial benefits including additional scale and geographic diversification in the physician professional liability market and 
is expected to be accretive to earnings over time; nevertheless, there are numerous risks and uncertainties around the 
transaction. The completion of our planned acquisition of NORCAL is subject to a number of conditions, including required 
regulatory approvals. The failure to satisfy all the required conditions could prevent the acquisition from occurring. In addition, 
regulators could impose additional requirements or obligations as conditions for their approval. We can provide no assurance 
that we will obtain the necessary approvals within the estimated timeframe or at all, or that any such requirements that are 

29

imposed by regulators would not result in the termination of the transaction. Investors’ reactions to a failure to complete the 
acquisition of NORCAL, including possible speculation about alternative uses of capital, may cause volatility in our stock 
price. A failure to complete a proposed transaction of this nature could also result in litigation by ProAssurance stockholders or 
by NORCAL or its policyholders asserting monetary harm due to the failure of the transaction.

In addition, even if we complete the proposed NORCAL acquisition, we may not be able to successfully integrate 

NORCAL into our business and therefore may not be able to achieve expected synergies. Furthermore, the significant 
disruptions on global financial markets as a result of the COVID-19 pandemic could impact the future operating performance of 
NORCAL negatively, as well as negatively impact the fair value of its assets and liabilities. Therefore, our liquidity may be 
adversely impacted should NORCAL's operating performance deteriorate, requiring our holding company to infuse capital into 
NORCAL or preventing the ability to distribute capital from NORCAL to our holding company due to regulatory restrictions or 
other reasons.

In early 2021, we plan to finance a portion of our acquisition of NORCAL. Our ability to arrange additional financing or 

refinancing will depend on, among other factors, our financial position and performance, as well as prevailing market 
conditions and other factors beyond our control. There can be no assurance that we will be able to obtain additional financing or 
refinancing, if needed, on terms acceptable to us or at all. If we are not able to access capital on acceptable terms, we may 
encounter difficulty funding the transaction, our business requirements, including debt repayments when they become due, or 
both. In addition, due to the impacts of the COVID-19 pandemic, we could experience loss of revenue and profits due to 
delayed payments or insolvency of insureds facing liquidity issues as well as lower yields on our investment portfolio. As a 
result, we may be compelled to take additional measures to preserve our cash flow, including the reduction of operating 
expenses or reduction or suspension of dividend payments, at least until the impacts of the COVID-19 pandemic improve. 
Further, the COVID-19 pandemic’s potential disruption to our business operations may require us to access our Revolving 
Credit Agreement which we have anticipated utilizing to partially fund the NORCAL transaction. Thus, we may be required to 
raise additional financing to fund working capital, capital expenditures, acquisitions or other general corporate requirements. 

Increased levels of indebtedness associated with the NORCAL transaction or due to meeting our operational needs could 

make us more vulnerable to general adverse economic, regulatory and industry conditions in a period of uncertainty and 
volatility. This indebtedness could have the effect, among other things, of reducing our flexibility to respond to changing 
business and economic conditions and increasing interest expense. The increased levels of indebtedness following completion 
of the acquisition could also reduce funds available for working capital, capital expenditures, acquisitions and other general 
corporate purposes and may create competitive disadvantages relative to other companies with lower debt levels. If we do not 
achieve the expected benefits and cost savings from the NORCAL acquisition, or if the financial performance of the combined 
company does not meet current expectations, our ability to service our indebtedness may be adversely impacted.

Any of these events could materially adversely affect our business, financial condition, results of operations, cash flows, 

liquidity and stock price.

Our success is dependent upon our ability to adequately and appropriately serve our customers.

The operations of the Company are heavily dependent upon the delivery of superior customer service across a broad 
customer base, by which negative feedback from agents, brokers, insureds or internal staff could result in a loss of revenue for 
the Company.

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

Our certificate of incorporation, bylaws and Delaware law contain provisions that may have the effect of inhibiting a non-
negotiated merger or other business combination. As of December 31, 2020, we currently have no preferred stock outstanding. 
In addition, our Corporate Governance Principles provide that the Board, subject to its fiduciary duties, will not issue any series 
of preferred stock for any defense or anti-takeover purpose, for the purpose of implementing any stockholders rights plan, or 
with features intended to make any acquisition more difficult or costly without obtaining stockholder approval. However, 
because the rights and preferences of any series of preferred stock may be set by the Board in its sole discretion, the rights and 
preferences of any such preferred stock may be superior to those of our common stock and thus may adversely affect the rights 
of the holders of common stock.

The voting structure of common stock and other provisions of our certificate of incorporation are intended to encourage a 

person interested in acquiring us to negotiate with and to obtain the approval of the Board in connection with a transaction. 
However, certain of these provisions may discourage our future acquisition, including an acquisition in which stockholders 
might otherwise receive a premium for their shares. As a result, stockholders who might desire to participate in such a 
transaction may not have the opportunity to do so.

30

In addition, state insurance laws provide that no person or entity may directly or indirectly acquire control of an insurance 

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

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

We are a holding company whose principal source of external revenue is our investment revenues. In addition, cash 
dividends and other permitted payments from operating subsidiaries represent another source of funds. If our subsidiaries are 
unable to make payments to us, or are able to pay only limited amounts, we may be unable to make payments on our 
indebtedness, meet other holding company financial obligations, or pay dividends to shareholders. The payment of dividends by 
these operating subsidiaries is subject to restrictions set forth in the insurance laws and regulations of their respective states of 
domicile, as discussed in Item I under the heading "Insurance Regulatory Matters."

Regulatory requirements or changes to regulatory requirements could have a material effect on our operations.

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

•
•
•
•
•

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

These regulations may impede or impose burdensome conditions on rate changes or other actions that we may desire to
take in order to enhance our results of operations. In addition, we may incur significant costs in the course of complying with 
regulatory requirements. Most states also regulate insurance holding companies like us in a variety of matters such as 
acquisitions, solvency and risk assessment, changes of control and the terms of affiliated transactions.

Also, certain states sponsor insurance entities which affect the amount and type of liability coverages purchased in the 

sponsoring state. Changes to the number of state sponsored entities of this type could result in a large number of insureds 
changing the amount and type of coverage purchased from private insurance entities such as ProAssurance.

We own two subsidiaries domiciled in the Cayman Islands and subject to the laws of the Cayman Islands and regulations 

promulgated by the CIMA. Failure to comply with these laws, regulations and requirements could result in consequences 
ranging from a regulatory examination to a regulatory takeover of our Cayman Islands subsidiaries, which could potentially 
impact profitability of alternative market solutions offered through these subsidiaries.

Syndicate 1729 and Syndicate 6131 are regulated in the U.K. by the Prudential Regulation Authority and the Financial 
Conduct Authority. All Lloyd's Syndicates must also comply with the bylaws and regulations established by the Council of 
Lloyd's. Failure to comply with bylaws and regulations could affect our ability to underwrite as a Lloyd's Syndicate in the 
future and therefore affect our profitability. Changes in bylaws and regulations could also affect the profitability of the 
operations.

Effective January 1, 2016, the European Union's executive body, the European Commission, implemented capital 
adequacy and risk management regulations called Solvency II that apply to businesses within the European Union. Syndicate 
1729 and Syndicate 6131 follow the Solvency II compliance guidelines set out by the Council of Lloyd's. 

The assessments that we are required to pay to state associations may increase or our participation in mandatory risk retention 
pools could be expanded and our results of operations and financial condition could suffer as a result.

Each state in which we operate has separate insurance guaranty fund laws requiring admitted property and casualty 
insurance companies doing business within their respective jurisdictions to be members of their guaranty associations. These 
associations are organized to pay covered claims (as defined and limited by the various guaranty association statutes) under 
insurance policies issued by insurance companies that have become insolvent. Most guaranty association laws enable the 
associations to make assessments against member insurers to obtain funds to pay covered claims after a member insurer 
becomes insolvent. These associations levy assessments (up to prescribed limits) on all member insurers in a particular state on 
the basis of the proportionate share of the premiums written by member insurers in the covered lines of business in that state. 
Maximum assessments generally vary between 1% and 2% of annual premiums written by a member in that state. Some states 

31

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. We had no significant guaranty fund 
recoupments or assessments in 2020, 2019 or 2018. Our practice is to accrue for insurance insolvencies when notified of 
assessments. We are not able to reasonably estimate assessments or develop a meaningful range of possible assessments prior to 
notice because the guaranty funds do not provide sufficient information for development of such estimates or ranges.

Certain states in which we write workers’ compensation insurance have established administrative and/or second injury 

funds that levy assessments against insurers that write business in their state. The assessments are generally based on an 
insurer’s proportionate share of premiums or losses in a particular state, and the assessment rate can vary from year to year.

Risk pooling mechanisms have been established in certain states that offer insurance coverage to individuals or entities 

who are otherwise unable to purchase coverage from private insurers. Authorized property and casualty insurers in these states 
are generally required to share in the underwriting results of these pooled risks, which are typically adverse. Should our 
mandatory participation in such pools be increased or if the assessments from such pools increased, our results of operations 
and financial condition would be negatively affected, although that was not the case in 2020, 2019 or 2018.

Our Board may decide that our financial condition does not allow the continued payment of a quarterly cash dividend, or 
requires that we reduce the amount of our quarterly cash dividend.

Our Board approved a cash dividend policy in September 2011, and we most recently paid a $0.05 per share dividend for 
the three months ended December 31, 2020. However, any decision to pay future cash dividends is subject to the Board’s final 
determination after a comprehensive review of the Company’s financial performance, future expectations and other factors 
deemed relevant by the Board.

The operations of the Company are heavily reliant upon the Company's reputation as an ethical business organization 
providing needed services to its customers.

The Company's positive reputation is critical to its role as an insurance provider and as a publicly traded company. The 
Board adopted a Code of Ethics and Conduct, and management is heavily focused on the integrity of our employees and third-
party suppliers, agents or brokers. Illegal, unethical or fraudulent activities perpetrated by an employee or one of our third-party 
agencies or brokers for personal gain could expose the Company to a potential financial loss.

A natural disaster or pandemic event, or closely related series of events, could cause loss of lives or a substantial loss of 
property or operational ability at one or more of the Company's facilities.

The Company's disaster preparedness encompasses our Business Continuity Plan, Disaster Recovery Plan, Operations 

Plan and Pandemic Response Plan. Our disaster preparedness is focused on maintaining the continuity of the Company's data 
processing and telephone capabilities as well as the use of alternate and temporary facilities in the event of a natural disaster or 
medical event. The Company's plans are reviewed during the insurance department examinations of the statutory insurance 
companies. While the Company has plans in place to respond to both short- and long-term disaster scenarios, the loss of certain 
key operating facilities or data processing capabilities could have a significant impact on Company operations.

The operations of the Company are dependent upon the security, integrity and availability of our internal technology 
infrastructure and that of certain third parties. Any significant disruption of these infrastructures could result in unauthorized 
access to Company data or reduce our ability to conduct business effectively, or both.

The Company is dependent upon its technology infrastructure and that of certain third parties to operate and report 
financial and other Company information accurately and timely. We collect, use, store or transmit an increasingly large amount 
of confidential, proprietary and other information in connection with the operation of our business. Therefore, the Company has 
focused resources on securing and preserving the integrity of our data processing systems and related data. Despite our efforts 
to ensure the integrity of our systems, we are increasingly exposed to the risk that our technology infrastructure could be subject 
to cyber-attacks and unauthorized access, such as physical and electronic break-ins or unauthorized tampering.

The Company also evaluates the integrity and security of the technology infrastructure of third parties that access, process 
or store data that the Company considers to be significant. While we review and assess our third party providers' cybersecurity 
controls, as appropriate, and make changes to our business processes to manage these risks, there is no guarantee that measures 
taken to date will completely prevent possible disruption, damage or destruction by intentional or unintentional acts or events 
such as cyber-attacks, viruses, sabotage, human error, system failure or the occurrence of numerous other human or natural 
events.

Disruption, damage or destruction of any of our systems or data could cause our normal operations to be disrupted, or 
unauthorized internal or external knowledge or misuse of confidential Company data could occur, all of which could be harmful 
to the Company from a financial, legal and reputational perspective. We continually enhance our cyber and information security 
in order to identify and neutralize emerging threats and improve our ability to prevent, detect and respond to attempts to gain 

32

unauthorized access to our data and systems. We regularly add additional security measures to our computer systems and 
network infrastructure to mitigate the possibility of cybersecurity breaches, including firewalls and penetration testing. 
However, it is impossible to defend against every risk being posed by changing technologies. The Company has a formal 
process in place for identifying, handling and disclosing of cybersecurity incidents. In addition, the Company's Board and Audit 
Committee are involved in the oversight of our cybersecurity policies and procedures and are continually updated on material 
cybersecurity risks and cybersecurity issues, if any, faced by executive management. To date, the Company is not aware of any 
material harm or loss relating to cyber-attacks or other security breaches at the Company or its third parties.

General

We are subject to numerous NYSE and SEC regulations including insider trading regulations, Regulation FD and regulations 
requiring timely and accurate reporting of our operating results as well as certain events and transactions. Noncompliance 
with these regulations could subject us to enforcement actions by the NYSE or the SEC, and could affect the value of our shares 
and our ability to raise additional capital.

The Company carefully adheres to NYSE and SEC requirements as the loss of trading privileges on the NYSE or an SEC 

enforcement action could have a significant financial impact on the Company. Failure to comply with various SEC reporting 
and record keeping requirements could result in a decline in the value of our stock or a decline in investor confidence which 
could directly impact our ability to efficiently raise capital. Failure to adhere to NYSE requirements could result in fines, 
trading restrictions or delisting.

In June 2020, a putative class action lawsuit was filed against the Company in the Northern District of Alabama, alleging 

violations of the Securities Exchange Act of 1934 and alleging that the Company made false and misleading statements 
regarding its Specialty Property and Casualty segment. The Company believes the lawsuit is without merit and intends to 
defend it vigorously; however, there can be no assurance regarding the ultimate outcome of the matter.

If we fail to maintain proper and effective internal controls over financial reporting, our operating results and our ability to 
operate our business could be harmed.

We continually enhance our operating procedures and internal controls to effectively support our operations and comply 

with our regulatory and financial reporting requirements. As a result of the inherent limitations in all control systems, no system 
of controls can provide absolute assurance that all control objectives have been or will be met, and that instances of fraud, if 
any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making 
can be faulty and that breakdowns can occur because of an error or mistake. Additionally, controls can be circumvented by the 
unauthorized and wrongful individual acts of some persons or by collusion of two or more persons. The design of any system of 
controls is based in part upon certain assumptions about the likelihood of future events and there can be no assurance that any 
design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become 
inadequate because of changes in conditions or the degree of compliance with policies or procedures may deteriorate. Further, 
the design of a control system must reflect the fact that resource constraints exist. Accordingly, our control system can provide 
only reasonable, not absolute, assurance of achieving the desired control objectives.

Our success is dependent upon our ability to effectively design and execute our business strategy. 

The Company depends upon the skill and work product of our officers and employees in executing our business strategy. 
While management and the Board monitor the strategic direction of the Company, strategic changes could be made that are not 
supportable by our capital base.

Our business could be affected by the loss of one or more of our senior executives or other qualified personnel.

We are heavily dependent upon our senior management, and the loss of services of our senior executives could adversely 
affect our business. Our success has been, and will continue to be, dependent on our ability to retain the services of existing key 
employees and to attract and retain additional qualified personnel in the future. The loss of the services of key employees or 
senior managers, or the inability to identify, hire and retain other highly qualified personnel in the future, could adversely affect 
the quality and profitability of our business operations. Our Board regularly reviews succession planning relating to our Chief 
Executive Officer as well as other senior officers.

Our insurance subsidiaries are involved in various legal actions, a substantial number of which arise from claims made 
under insurance policies. While the outcome of all legal actions is not presently determinable, management and its legal counsel

Note 9 of the Notes to Consolidated Financial Statements included herein.

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

The following discussion generally focuses on the change in financial condition, results of operation and cash flows for 

the year ended December 31, 2020 as compared to the year ended December 31, 2019 and be should be read in conjunction 
with the Consolidated Financial Statements and Notes to those statements which accompany this report. For a full discussion of 
the changes in the financial condition, results of operations and cash flows for the year ended December 31, 2019 as compared 
to the year ended December 31, 2018, please refer to Item 7, "Management's Discussion and Analysis of Financial Condition 
and Results of Operations" section of ProAssurance's December 31, 2019 report on Form 10-K.

Throughout the discussion we use certain terms and abbreviations, which can be found in the Glossary of Terms and 
Acronyms at the beginning of this report. In addition, 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 significant risks, assumptions and uncertainties. As discussed under the heading "Caution Regarding 
Forward-Looking Statements," our actual financial condition and results of operations could differ significantly from these 
forward-looking statements.

ProAssurance Overview

ProAssurance Corporation is a holding company for property and casualty insurance companies. Our wholly owned 
insurance subsidiaries provide professional liability insurance, liability insurance for medical technology and life sciences risks 
and workers' compensation insurance. We also provide capital to Syndicate 1729 and Syndicate 6131 at Lloyd's of London. 

We operate in five segments which are based on our internal management reporting structure for which financial results 

are regularly evaluated by our CODM to determine resource allocation and assess operating performance. Descriptions of 
ProAssurance's five operating and reportable segments are as follows:

•

Specialty P&C - This segment includes our professional liability business and medical technology liability
business. Our professional liability insurance is primarily comprised of medical professional liability products
offered to healthcare providers and institutions. We also offer, to a lesser extent, professional liability insurance to
attorneys and their firms. Medical technology liability insurance is offered to medical technology and life sciences
companies that manufacture or distribute products including entities conducting human clinical trials. We also offer
custom alternative risk solutions including loss portfolio transfers, assumed reinsurance and captive cell programs
for healthcare professional liability insureds. For our alternative market captive cell programs, we cede either all or
a portion of the premium to certain SPCs in our Segregated Portfolio Cell Reinsurance segment.

• Workers' Compensation Insurance - This segment includes our workers' compensation insurance business which is
provided primarily to employers with 1,000 or fewer employees. Our workers' compensation products include
guaranteed cost policies, policyholder dividend policies, retrospectively-rated policies, deductible policies and
alternative market solutions. Alternative market program premiums are 100% ceded to either SPCs in our
Segregated Portfolio Cell Reinsurance segment or, to a limited extent, an unaffiliated captive insurer.

•

Segregated Portfolio Cell Reinsurance - This segment includes the results (underwriting profit or loss, plus
investment results, net of U.S. federal income taxes) of SPCs at Inova Re and Eastern Re, our Cayman Islands SPC
operations. Each SPC is owned, fully or in part, by an agency, group or association, and the results of the SPCs are
attributable to the participants of that cell. We participate to a varying degree in the results of selected SPCs and,
for the SPCs in which we participate, our participation interest ranges from a low of 20% to a high of 85%. SPC
results attributable to external cell participants are reflected as an SPC dividend expense (income) in our
Segregated Portfolio Cell Reinsurance segment. The SPCs assume workers' compensation insurance, healthcare
professional liability insurance or a combination of the two from our Workers' Compensation Insurance and
Specialty P&C segments.

• Lloyd's Syndicates - This segment includes the results from our participation in Lloyd's of London Syndicate 1729
(29% for the 2020 underwriting year) and Syndicate 6131 (100% for the 2020 underwriting year). The results of
this segment are normally reported on a quarter lag, except when information is available that is material to the
current period. Syndicate 1729 underwrites risks over a wide range of property and casualty insurance and
reinsurance lines in both the U.S. and international markets while Syndicate 6131 focuses on contingency and
specialty property business, also within the U.S. and international markets. To support and grow our core insurance
operations, we decreased our participation in the results of Syndicate 1729 for the 2021 underwriting year to 5%
from 29%. Syndicate 6131 is an SPA that underwrites on a quota share basis with Syndicate 1729. Effective July 1,
2020, Syndicate 6131 entered into a six-month quota share reinsurance agreement with an unaffiliated insurer.
Under this agreement, Syndicate 6131 ceded essentially half of the premium assumed from Syndicate 1729 to the

38

unaffiliated insurer; the agreement was non-renewed on January 1, 2021 and we decreased our participation in the 
results of Syndicate 6131 to 50% from 100% for the 2021 underwriting year. Due to the quarter lag, the change in 
our participation in the results of Syndicates 1729 and 6131 will not be reflected in our results until the second 
quarter of 2021.

• Corporate - This segment includes our investment operations, other than those reported in our Segregated Portfolio
Cell Reinsurance and Lloyd's Syndicates segments, interest expense and U.S. income taxes. This segment also
includes non-premium revenues generated outside of our insurance entities and corporate expenses.

Additional information regarding our segments is included in Note 16 of the Notes to Consolidated Financial Statements, 

Part I and in the Segment Results sections that follow.

Growth Opportunities and Outlook

Over the long-term we expect our growth to come primarily through controlled expansion of our existing operations. In 

addition, from time to time, we may identify opportunities for growth through the acquisition of other insurers, service 
providers or books of business. In early 2020, we entered into a definitive agreement to acquire NORCAL, an underwriter of 
medical professional liability insurance, subject to the demutualization of NORCAL Mutual, NORCAL's ultimate controlling 
party. If consummated, the transaction will provide strategic and financial benefits including additional scale and geographic 
diversification in the physician professional liability market. Upon satisfaction of the various remaining regulatory approvals 
required, we are anticipating to close the transaction in the second quarter of 2021.  See further discussion under the heading 
"Acquisitions" in the Liquidity and Capital Resources and Financial Condition section that follows. We continue to see new 
opportunities from each of our acquisitions and believe each will provide organic growth through expansion in their existing 
markets and relationships.

We operate in very competitive markets and face strong competition from other insurance companies for all of our 
insurance products. HCPL insurance represents the largest product line in our gross premiums written (41% in 2020) and the 
healthcare market has been trending toward the formation of larger medical practice groups and the employment of physicians 
by hospitals. Large medical groups and facilities frequently manage their healthcare professional liability exposure outside of 
the traditional first dollar insurance marketplace using self-insured mechanisms and other risk sharing arrangements. In 
response to these trends, we offer products designed to provide greater risk sharing options to hospitals and large physician 
groups. Since the middle of 2019, new senior leadership in our Specialty P&C segment has executed a comprehensive 
underwriting strategy in response to emerging loss trends and changing conditions in the HCPL industry. This includes 
organizational structure enhancements, recruitment of additional talent in specialty underwriting, focus on state strategies to 
achieve greater concentration and predictability, price strengthening and tightening of underwriting criteria, terms and 
conditions. Furthermore, the new senior leadership team for our Specialty P&C segment executed several strategic business 
decisions intended to improve operating performance by bringing together all of the Specialty P&C segment lines of business 
and operations under a unified organizational and management structure.

Our operations at Eastern, a provider of workers' compensation insurance, currently represents the second largest product 
line in our gross premiums written (29% in 2020, including alternative market premiums). The workers’ compensation industry 
is highly competitive in the geographic markets in which we operate and multi-line insurers continue to increase their leverage 
of workers’ compensation business in their product offerings. We believe our workers' compensation product offerings allow us 
to provide flexibility in offering solutions to our customers at a competitive price. In addition, we believe that our claims 
handling and risk management services are attractive to our customers and provide us with a competitive advantage even when 
our pricing is higher than our competitors. 

Beginning in 2014, we started participating in and providing capital to Syndicate 1729 and beginning in 2018, began 

participating in and providing capital to Syndicate 6131. Our participation in Syndicate 1729 for the 2014 through 2020 
underwriting years has ranged from a low of 29% to a high of 62%. Our participation in Syndicate 6131 was 100% for the 2018 
through 2020 underwriting years. Our Lloyd's Syndicates segment represents 10% of our gross premiums written in 2020. For 
the 2021 underwriting year, we have decreased our participation in Syndicate 1729 (to 5% from 29%) and Syndicate 6131 (to 
50% from 100%) in order to support and grow our core insurance operations, as previously discussed.

With the changes in executive leadership beginning in 2019, we have performed a detailed strategic review which led us 

to make significant organizational adjustments to our operating structure which we believe will improve our ability to grow our 
business profitably while strengthening our industry leading products and services. This review included consideration of the 
external environment on our business, agency partners’ operations and valued customer base, with the ultimate goal of 
enhancing our service platform to meet the ever-changing needs of the marketplace. 

COVID-19 continues to present challenges for all in the insurance marketplace. Policyholders, agency partners and 
insurance carriers are conducting business in ways never before considered, and some of these changes may persist even after 
the pandemic subsides. We believe our enhanced operating structure and strategy have positioned us well to face these 
challenges and support our policyholders and agency partners as we navigate the current environment.

39

We believe our emphasis on the fair treatment of our insureds and other important stakeholders through our commitment 
to “Treated Fairly” has enhanced our market position and differentiated us from other insurers. We will continue to practice our 
values of integrity, leadership, relationships and enthusiasm in all of our activities. We will honor these values in the execution 
of “Treated Fairly” to perform our Mission and realize our Vision. We believe that as we reach more customers with this 
message we will continue to improve retention and add new insureds.

Key Performance Measures

We are committed to disciplined underwriting, pricing and loss reserving practices as well as conservative investment 

practices, even during difficult market conditions. We are also committed to maintaining prudent operating and financial 
leverage. We recognize the importance that our customers and producers place on the financial strength of our insurance 
subsidiaries, and we manage our business to protect our financial security.

In evaluating our performance, we consider a number of performance measures, including the following:

•

•

•

•

•

•

•

•

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

We particularly focus on our combined ratio and investment returns, both of which directly affect our ROE and growth in 
our book value. We currently target a dynamic long-term ROE of 700 basis points above the 10-year U.S. Treasury rate, which 
at December 31, 2020 was approximately 7.9%.

Our emphasis on rate adequacy, selective underwriting, effective claims management and prudent investments is a key 
factor in our ability to achieve our long-term ROE target. We closely monitor premium revenues, losses and loss adjustment 
expenses, 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, these activities, such as insurance agency services, do not constitute a 
significant use of our resources or a significant source of revenues or profits.

Critical Accounting Estimates

Our Consolidated Financial Statements are prepared in conformity with 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. We can make 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.

As a result of the COVID-19 pandemic, we are reevaluating certain of these estimates and assumptions which could result 
in material changes to our results of operations including, but not limited to, higher losses and loss adjustment expenses, lower 
premium volume, asset impairment charges, declines in investment valuations, reductions in audit premium estimates, deferred 
tax valuation allowances and increases in the allowance for expected credit losses related to available-for-sale securities, 
premiums receivable and reinsurance receivables. The extent to which the COVID-19 pandemic impacts our business, results of 
operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted. 
These factors include, but are not limited to, the duration, spread, severity, reemergence or mutation of the COVID-19 
pandemic, development and wide-scale distribution of medicines or vaccines that effectively treat the virus, the effects of the 
COVID-19 pandemic on our insureds, the loss environment, the healthcare industry, the labor market and Lloyd's, the actions 
and stimulus measures taken by governments and governmental agencies, and to what extent normal economic and operating 
conditions can resume. Even after the COVID-19 pandemic has subsided, we may experience an impact to our business as a 
result of any economic recession that has occurred or may occur in the future. Please see "Item 1A, Risk Factors" included in 
this report for additional information.

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

management and those judgments could result in a material effect on our financial statements.

Reserve for Losses and Loss Adjustment Expenses

The largest component of our liabilities is our reserve for losses and loss adjustment expenses ("reserve for losses" or 

"reserve"), and the largest component of expense for our operations is incurred losses and loss adjustment expenses (also 
referred to as “losses and loss adjustment expenses,” “incurred losses,” “losses incurred” and “losses”). Incurred losses reported 
in any period reflect our estimate of losses incurred related to the premiums earned in that period as well as any changes to our 
previous estimate of the reserve required for prior periods.

As of December 31, 2020, our reserve is comprised almost entirely of long-tail exposures. The estimation of long-tailed 
losses is inherently difficult and is subject to significant judgment on the part of management. Due to the nature of our claims, 
our loss costs, even for claims with similar characteristics, can vary significantly depending upon many factors, including but 
not limited to the specific characteristics of the claim and the manner in which the claim is resolved. Long-tailed insurance is 
characterized by the extended period of time typically required both to assess the viability of a claim and potential damages, if 
any, and to reach a resolution of the claim. The claims resolution process may extend to more than five years. The combination 
of continually changing conditions and the extended time required for claim resolution results in a loss cost estimation process 
that requires actuarial skill and the application of significant judgment, and such estimates require periodic modification.

Our reserve is established by management after taking into consideration a variety of factors including premium rates, 
historical paid and incurred loss development trends and our evaluation of the current loss environment including frequency, 
severity, the expected effect of inflation, general economic and social trends, and the legal and political environment. We also 
take into consideration the conclusions reached by our internal and consulting actuaries. We update and review the data 
underlying the estimation of our reserve for losses each reporting period and make adjustments to loss estimation assumptions 
that we believe best reflect emerging data. Both our internal and consulting actuaries perform an in-depth review of our reserve 
for losses on at least a semi-annual basis using the loss and exposure data of our insurance subsidiaries.

We partition our reserves by accident year, which is the year in which the claim becomes our liability. For claims-made 

policies, the insured event generally becomes a liability when the event is first reported to us. For occurrence policies, the 
insured event becomes a liability when the event takes place. For retroactive coverages, the insured event becomes a liability at 
inception of the underlying contract. As claims are incurred (reported) and claim payments are made, they are aggregated by 
accident year for analysis purposes. We also partition our reserves by reserve type: case reserves and IBNR reserves. Case 
reserves are established by our claims departments 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 for an individual claim is the case reserve at any point in time plus the claim payments 
that have been made to date. IBNR reserves represent our estimate in the aggregate of future development on losses that have 
been reported to us and our estimate of losses that have been incurred but not reported to us.

41

Our reserving process can be broadly grouped into three areas: the establishment of the reserve for the current accident 

year (the initial reserve), the re-estimation of the reserve for prior accident years (development of prior accident years) and the 
establishment of the initial reserve for risks assumed in business combinations, applicable only in periods in which acquisitions 
occur (the acquired reserve). A summary of the activity in our net reserve for losses during 2020 and 2019 is provided under the 
heading "Losses" in the Liquidity and Capital Resources and Financial Condition section that follows.

Current Accident Year - Initial Reserve

Considerable judgment is required in establishing our initial reserve for any current accident year period, as there is 

limited data available upon which to base our estimate (see further discussion that follows under the heading "Uses of 
Judgment"). Our process for setting an initial reserve considers the unique characteristics of each product, but in general we rely 
heavily on the loss assumptions that were used to price business, as our pricing reflects our analysis of loss costs that we expect 
to incur relative to the insurance product being priced. 

Specialty P&C Segment. Loss costs within this segment are impacted by many factors including but not limited to the 

nature of the claim, including whether or not the claim is an individual or a mass tort claim, the personal situation of the 
claimant or the claimant's family, the outcome of jury trials, the legislative and judicial climate where any potential litigation 
may occur, general economic and social trends and, for claims involving bodily injury, the trend of healthcare costs. Within our 
Specialty P&C segment, for our professional liability business (80% of our consolidated gross reserve for losses and loss 
adjustment expenses as of December 31, 2020; predominately comprised of our HCPL products), we set an initial reserve based 
upon our evaluation of the current loss environment including frequency, severity, economic inflation, social inflation and legal 
trends. 

The current accident year net loss ratio in the Specialty P&C segment has ranged from 87% to 106% in recent years, 

excluding the effect of a single large national healthcare account that generated outsized losses and distorted results for 2019 
and 2020. We recorded a higher than average current accident year net loss ratio in 2019 due to increased reserve estimates 
related to this large national healthcare account that exceeded the assumptions we made when originally underwriting the 
account. During the second quarter of 2020, the policy term associated with this account's claims-made coverage expired. This 
account did not renew on terms offered by us and the insured exercised its contractual option to purchase the extended reporting 
endorsement or "tail" coverage resulting in a net underwriting loss of $45.7 million recognized in the second quarter of 2020 
associated with this policy, which increased our current accident year net loss ratio for the year ended December 31, 2020. 
Excluding the impact of this large national healthcare account, the current accident year net loss ratio was 94.7% for the year 
ended December 31, 2020. This reflects loss severity in the broader medical professional liability industry and a higher loss 
pick in our Specialty line of business. 

During 2020, we have observed a reduction in claims frequency as compared to 2019, some of which is likely associated 

with the COVID-19 pandemic; however, we have remained cautious in recognizing these favorable frequency trends in our 
current accident year reserve due to the long-tailed nature of our HCPL claims as well as the uncertainty surrounding the length 
and severity of the pandemic. During 2020, we established a $10 million reserve related to COVID-19. This reserve represents 
our best estimate of ultimate COVID-19 related losses based on currently available information and reported incidents; no 
adjustment has been made to this reserve since the second quarter of 2020. See further discussion in our Segment Results - 
Specialty Property & Casualty section that follows under the heading "Losses and Loss Adjustment Expenses."

The risks insured in our Medical Technology Liability business (3% of our consolidated gross reserve for losses and loss 

adjustment expenses as of December 31, 2020) are more varied, and policies are individually priced based on the risk 
characteristics of the policy and the account. The insured risks range from startup operations to large multinational entities, and 
the larger entities often have significant deductibles or self-insured retentions. Reserves are established using our most recently 
developed actuarial estimates of losses expected to be incurred based on factors which include results from prior analysis of 
similar business, industry indications, observed trends and judgment. Claims in this line of business primarily involve bodily 
injury to individuals and are affected by factors similar to those of our HCPL line of business. For the Medical Technology 
Liability business, we also establish an initial reserve using a loss ratio approach, including a provision in consideration of 
historical loss volatility that this line of business has exhibited. 

Workers' Compensation Insurance Segment. Many factors affect the ultimate losses incurred for our workers' 

compensation coverages (8% of our consolidated gross reserve for losses and loss adjustment expenses as of December 31, 
2020) including but not limited to the type and severity of the injury, the age, health and occupation of the injured worker, the 
estimated length of disability, medical treatment and related costs, and the jurisdiction and workers' compensation laws of the 
state of the injury occurrence. 

We use various actuarial methodologies in developing our workers’ compensation reserve, combined with a review of the 

payroll exposure base. For the current accident year, given the lack of seasoned information, the different actuarial 
methodologies produce results with significant variability; therefore, more emphasis is placed on supplementing results from 

42

the actuarial methodologies with trends in exposure base, medical expense inflation, general inflation, severity, and claim 
counts, among other things, to select an expected loss ratio.

Similar to our Specialty P&C segment, we have also observed a reduction in claims frequency in our Workers' 

Compensation Insurance segment, some of which is likely associated with the COVID-19 pandemic. During the third quarter of 
2020, we reduced our current accident year net loss ratio in response to the continuation of favorable trends in 2020, including 
lower claims frequency and severity, as our workers' compensation claims are shorter-tailed in nature as compared to our HCPL 
claims; however, we remain cautious in our evaluation of the current accident year reserve due to uncertainty surrounding the 
length and severity of the pandemic, and legislative and regulatory bodies in certain states changing or attempting to broaden 
compensability requirements for COVID-19 claims. If these legislative and regulatory bodies are successful, it could have an 
adverse impact on the frequency and severity related to COVID-19 claims. See previous discussion in Part I under the heading 
"Insurance Regulatory Matters- COVID-19." Furthermore, as it relates to both our Workers' Compensation Insurance and 
Segregated Portfolio Cell Reinsurance segments, the current economic conditions resulting from the COVID-19 pandemic have 
introduced significant risk of a prolonged recession, which could have an adverse impact on our return to wellness efforts and 
the ability of injured workers to return to work, resulting in a potential reduction in favorable claim trends in future periods.

Segregated Portfolio Cell Reinsurance Segment. The factors that affect the ultimate losses incurred for the workers' 
compensation and HCPL coverages assumed by the SPCs at Inova Re and Eastern Re (4% of our consolidated gross reserve for 
losses and loss adjustment expenses as of December 31, 2020) are consistent with that of our Workers’ Compensation 
Insurance and Specialty P&C segments, respectively.

Lloyd's Syndicates Segment. Initial reserves for Syndicate 1729 and Syndicate 6131 are primarily recorded using the loss 
assumptions by risk category incorporated into each Syndicate's business plan submitted to Lloyd's with consideration given to 
loss experience incurred to date (5% of our consolidated gross reserve for losses and loss adjustment expenses as of 
December 31, 2020). The assumptions used in each business plan are consistent with loss results reflected in Lloyd's historical 
data for similar risks. The loss ratios may also fluctuate due to the mix of earned premium from different open underwriting 
years which we participate in to varying degrees, as well as the timing of earned premium adjustments. Such adjustments may 
be the result of premiums for certain policies and assumed reinsurance contracts being reported subsequent to the coverage 
period and may be subject to adjustment based on loss experience. Premium and exposure for some of Syndicate 1729's 
insurance policies and reinsurance contracts are initially estimated and subsequently recorded over an extended period of time 
as reports are received under delegated underwriting authority programs. When reports are received, the premium, exposure and 
corresponding loss estimates are revised accordingly. Changes in loss estimates due to premium or exposure fluctuations are 
incurred in the accident year in which the premium is earned. 

For significant property catastrophe exposures, Syndicate 1729 uses third-party catastrophe models to accumulate a listing 
of potentially affected policies. Each identified policy is given an estimate of loss severity based upon a combination of factors 
including the probable maximum loss of each policy, market share analytics, underwriting judgment, client/broker estimates 
and historical loss trends for similar events. These models are inherently uncertain, reliant upon key assumptions and 
management judgment and are not always a representation of actual events and ensuing potential loss exposure. Determination 
of actual losses may take an extended period of time until claims are reported and resolved, including coverage litigation.

Development of Prior Accident Years

In addition to setting the initial reserve for the current accident year, each period we reassess the amount of reserve 

required for prior accident years.

The foundation of our reserve re-estimation process is an actuarial analysis that is performed by both our internal and 
consulting actuaries. This very detailed analysis projects ultimate losses based on partitions which include line of business, 
geography, coverage layer and accident year. The procedure uses the most representative data for each partition, capturing its 
unique patterns of development and trends. We believe that the use of consulting actuaries provides an independent view of our 
loss data as well as a broader perspective on industry loss trends.

For the Specialty P&C, Workers' Compensation Insurance and Segregated Portfolio Cell Reinsurance segments, the 

analysis performed by the consulting actuaries analyzes each partition of our business in a variety of ways and uses multiple 
actuarial methodologies in performing these analyses, including:

•
•
•
•
•

Bornhuetter-Ferguson (Paid and Reported) Method
Paid Development Method
Reported (Incurred) Development Method
Average Paid Value Method
Average Reported Value Method

A brief description of each method follows.

43

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 expected losses. The weights assigned to the initial expected 
losses decrease as the accident year matures.

Paid Development and Reported (Incurred) Development Methods. These methods use historical, cumulative losses (paid 

losses for the Paid Development Method, reported losses for the Reported (Incurred) 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 (Incurred) 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.

Generally, methods such as the Bornhuetter-Ferguson Method are used on more recent accident years where we have less 

data on which to base our analysis. As time progresses and we have an increased amount of data for a given accident year, we 
begin to give more confidence to the development and average methods, as these methods typically rely more heavily on our 
own historical data. These methods emphasize different aspects of loss reserve estimation and provide a variety of perspectives 
for our decisions.

Certain of the methodologies utilized to estimate the ultimate losses for each partition of our reserves consider the actual 

amounts paid. Paid data is particularly influential when a large portion of known claims have been closed, as is the case for 
older accident years. In selecting a point estimate for each partition, management considers the extent to which trends are 
emerging consistently for all partitions and known industry trends. Thus, actual, rather than estimated severity trends are given 
more consideration. If actual severity trends are lower than those estimated at the time that reserves were previously 
established, the recognition of favorable development is indicated. This is particularly true for older accident years where our 
actuarial methodologies give more weight to actual loss costs (severity).

The various actuarial methods discussed above are applied in a consistent manner from period to period. In addition, we 
perform statistical reviews of claims data such as claim counts, average settlement costs and severity trends when establishing 
our reserves.

We utilize the selected point estimates of ultimate losses to develop estimates of ultimate losses recoverable from 

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

For our Workers’ Compensation Insurance segment and for the workers' compensation exposures in our Segregated 
Portfolio Cell Reinsurance segment, we utilize the Reported (Incurred) Development Method, Paid Development Method and 
Bornhuetter-Ferguson Method, to develop our reserve for each accident year. The actuarial review includes the stratification of 
claims data (lost time claims, medical only claims) using different variations that allow us to identify trends that may not be 
readily identifiable if the data was evaluated only in the aggregate. Reported and paid loss development factors are key 
assumptions in the reserve estimation process and are based on our historical reported and paid loss development patterns. As 
accident years mature, the various actuarial methodologies produce more consistent loss estimates.

For our Lloyd's Syndicates segment we rely on the analysis of actual loss experience on the book of business written by 

Syndicate 1729 to determine loss development by accident year.

Acquired Reserve

The acquisition of Eastern on January 1, 2014 increased our loss reserve by $153.2 million which represented the fair 

value of Eastern's loss reserve at the time of the acquisition. The fair value of the reserve for losses and loss adjustment 
expenses and related reinsurance recoverables was based on an actuarial estimate of the expected future net cash flows, a 
reduction of those cash flows for the time value of money determined utilizing the U.S. Treasury Yield Curve, and a risk 
adjustment to reflect the net present value of profit that an investor would demand in return for the assumption of the associated 
risks. Expected net cash flows were derived from the expected loss payment patterns included in an actuarial analysis of 
Eastern's reserve performed as of December 31, 2013. The fair value of the reserve, including the risk margin discussed above, 
exceeded the undiscounted loss reserve previously established by Eastern by $9.3 million; this fair value adjustment was 

44

amortized over the average expected life of the reserve of 6 years. The fair value adjustment was fully amortized as of 
December 31, 2019.

Use of Judgment

The process of estimating reserves involves a high degree of judgment and is subject to a number of variables. These 

variables can be affected by both views of internal and external events, such as changes in views of economic inflation, legal 
trends and legislative changes, as well as differentiating views of individuals involved in the reserve estimation process, among 
others. We continually refine our estimates in a regular, ongoing process as historical loss experience develops and additional 
claims are reported and settled. Our objective is to consider all significant facts and circumstances known at the time.

Changes in economic conditions and steps taken by the federal government and the Federal Reserve in response to 

COVID-19 could lead to inflation trends that are different from those we anticipated when establishing our reserves, which 
could in turn lead to an increase or decrease in our loss costs and the need to strengthen or reduce reserves. These impacts of 
inflation on loss costs and reserves could be more pronounced for our HCPL line of business as that business generally requires 
a longer period of time to settle claims for a given accident year and, accordingly, is relatively more inflation sensitive.

We use various actuarial methods in the process of setting reserves. Each actuarial method generally returns a different 
value, and for the more recent accident years the variations among the various methodologies can be significant. In order to 
project ultimate losses, we partition our reserves for analysis such as by line of business, geography, coverage layer or accident 
year. For each partition of our reserves, we evaluate the results of the various methods, along with the supplementary statistical 
data regarding such factors as closed with and without indemnity ratios, claim severity trends, the expected duration of such 
trends, changes in the legal and legislative environment and the current economic environment to develop a point estimate 
based upon management's judgment and past experience. The series of selected point estimates is then combined to produce an 
overall point estimate for ultimate losses.

HCPL. Over the past several years the most influential factor affecting the analysis of our HCPL reserves and the related 
development recognized has been an observed increase in claim severity for the broader medical professional liability industry 
as well as higher initial loss expectations on incurred claims. The severity trend is an explicit component of our pricing models 
and directly impacts the reserving process. Our estimate of this trend and our expectations about changes in this trend impact a 
variety of factors, from the selection of expected loss ratios to the ultimate point estimates established by management.

Because of the implicit and wide-ranging nature of severity trend assumptions on the loss reserving process, it is not 
practical to specifically isolate the impact of changing severity trends. However, because severity is an explicit component of 
our HCPL pricing process we can better isolate the impact that changing severity can have on our loss costs and loss ratios in 
regards to our pricing models for this business component. Our current HCPL pricing models assume severity trends in the 
range of 2% to 5% depending on state, territory and specialty. In some portions of our HCPL business we have observed and 
reflected higher severity trends in our estimates of losses and loss adjustment expenses. 

Due to the long-tailed nature of our claims and the previously discussed historical volatility of loss costs, selection of a 

severity trend assumption is a subjective process that is inherently likely to prove inaccurate over time. Given the long tail and 
volatility, we are generally cautious in making changes to the severity assumptions within our pricing models. All open claims 
and accident years are generally impacted by a change in the severity trend, which compounds the effect of such a change.

Although the future degree and impact of the ultimate severity trend remains uncertain due to the long-tailed nature of our 

business, we have given consideration to observed loss costs in setting our rates. For our HCPL business, this practice had 
generally resulted in rate reductions as claim frequency declined and remained at historically low levels. However, from early 
2017 to the current period, the average pricing on renewed business has steadily increased reflective of the rising loss cost 
environment, and we anticipate further renewal pricing increases due to increasing loss severity.

Workers' Compensation. The projection of changes in claim severity trend has not historically been an influential factor 

affecting our analysis of workers' compensation reserves, as claims are typically resolved more quickly than the industry norm. 
As previously mentioned, the determination and calculation of loss development factors, in particular, the selection of tail 
factors which are used to extend the projection of losses beyond historical data, requires considerable judgment.

Loss Development by Line of Business

Professional Liability

Our professional liability line of business includes both our HCPL and Small Business Unit lines, with our HCPL line 
representing the largest component of our reserve. In support of our concern that the decline in frequency will result in a higher 
severity trend for our HCPL claims, we saw our closed-with-indemnity-payment ratio (i.e., the number of claims closed with an 
indemnity or loss payment as compared to the total number of closed claims) for our claims increase from 10% in 2005 to 18% 
in 2020.

The following table presents additional information about the loss development for our professional liability line of 

business, excluding loss development for HCPL coverages assumed by the SPCs at Inova Re and Eastern Re:

During 2020, we have also observed a significant reduction in claims frequency as compared to 2019, some of which is 

likely associated with the COVID-19 pandemic and the disruption of the court systems; however, we have remained cautious in 
recognizing these favorable frequency trends in our current accident year reserve due to the long-tailed nature of HCPL claims 
as well as the uncertainty surrounding the length and severity of the pandemic. Development recognized during 2020 
principally related to accident years 2014 through 2017. Not included in the above table, as previously discussed, is 
$4.4 million of favorable development recognized during 2020 in our Segregated Portfolio Cell Reinsurance segment related to 
the HCPL coverages assumed by the SPCs at Inova Re and Eastern Re. During 2019 the loss experience in our Specialty line of 
business deteriorated further, particularly in regard to the reserves we established for a large national healthcare account, as 
previously discussed. This deterioration is the primary driver of the unfavorable development we recognized in 2019 for 
accident years 2016 through 2018. During the year ended December 31, 2018, reflection of higher severity trends in the 
Specialty line of business also resulted in increases of estimated ultimate losses for open claims for earlier accident years, which 
resulted in a lower amount of favorable development recognized in 2018 as compared to earlier years.

This can also be seen in looking at both the absolute amount of reserve development recognized for the less developed 
accident years as well as the size of such development when compared to established ultimates for those same accident years at 
the end of the preceding calendar year. The following table provides this information for years ended December 31, 2020, 2019 
and 2018 with respect to the three then most recent prior accident years:

Approximately $5.3 million of the $8.6 million total net favorable development recognized in 2020 related to the 2017 
through 2019 accident years. The development for the 2017 through 2019 accident years represents a 13.7% reduction to the 
ultimates established for those reserves at December 31, 2019. Approximately $6.8 million of the $12.8 million total net 
favorable development recognized in 2019 related to the 2014 through 2017 accident years. The development for the 2014 
through 2017 accident years represents a 13.7% reduction to the ultimates established for those reserves at December 31, 2018. 
Approximately $5.7 million of the $13.3 million total net favorable development recognized in 2018 related to the 2013 through 
2016 accident years. The development for the 2013 through 2016 accident years represents a 12.3% reduction to the ultimates 
established for those reserves at December 31, 2017.

In 2020, 2019 and 2018 the development was largely attributable to favorable results from claims closed during the year. 

As time has elapsed we have recognized that actual loss experience has on average been better than estimated. We have been 
cautious in recognizing the improvement, but as claims have matured and claims are closed or have become more certain for the 
remaining open claims, we have revised reserve estimates. We believe the need for a cautious approach is required as outcomes 
are uncertain and results can be significantly affected by outcomes for a small number of cases.

47

Workers' Compensation

Claims in our workers’ compensation line of business have historically closed at a faster rate than in our HCPL or 

Medical Technology Liability lines of business. This faster disposition rate, along with a lower net retention after the 
application of reinsurance, has resulted in less volatility in loss estimates on a net basis. However, a change in the number of 
individually-severe claims can create volatility in a given accident year. The following table presents additional information 
about the loss development for our workers' compensation line of business:

In 2020, we recognized $12.1 million of net favorable development in our Segregated Portfolio Cell Reinsurance segment 

related to workers' compensation business and $7.0 million of net favorable development in our Workers' Compensation 
Insurance segment. In 2019, we recognized $10.1 million of net favorable development in our Segregated Portfolio Cell 
Reinsurance segment, all related to workers' compensation business, and $7.8 million of net favorable development in our 
Workers' Compensation Insurance segment. In 2018, we recognized $9.0 million of net favorable development in our 
Segregated Portfolio Cell Reinsurance segment, all related to workers' compensation business, and $8.0 million of net favorable 
development in our Workers' Compensation Insurance segment. During the years ended December 31, 2019 and 2018, net 
favorable development in our Workers' Compensation Insurance segment included $1.6 million related to the amortization of 
the purchase accounting fair value adjustment. As previously discussed, this fair value adjustment has been fully amortized as 
of December 31, 2019.

Variability of Loss Reserves

As previously noted, the number of data points and variables considered and the subjective process followed in 

establishing our loss reserve makes it impractical to isolate individual variables and demonstrate their impact on our estimate of 
loss reserves. However, to provide a better understanding of the potential variability in our reserves, we have modeled implied 
reserve ranges around our single point net reserve estimates for our various lines of 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 
correlations 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 consolidated 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

Carried Net Reserve

High End Point

$1.540 billion

$2.032 billion

$2.615 billion

$1.668 billion

$2.032 billion

$2.357 billion

Any change in our estimate of net ultimate losses for prior years is reflected in net income (loss) in the period in which 

such changes are made. 

Due to the size of our consolidated reserve for losses and the large number of claims outstanding at any point in time, 
even a small percentage adjustment to our total reserve estimate could have a material effect on our results of operations for the 
period in which the adjustment is made, as was the case in 2020, 2019 and 2018.

48

Reinsurance

We use insurance and reinsurance (collectively, “reinsurance”) to provide capacity to write larger limits of liability, to 
provide reimbursement for losses incurred under the higher limit coverages we offer, to provide protection against losses in 
excess of policy limits and, in the case of risk sharing arrangements, to align our objectives with those of our strategic business 
partners and to provide custom insurance solutions for large customer groups. The purchase of reinsurance does not relieve us 
from the ultimate risk on our policies; however, it does provide reimbursement for certain losses we pay.

We make a determination of the amount of insurance risk we choose to retain based upon numerous factors, including our 
risk tolerance and the capital we have to support it, the price and availability of reinsurance, the volume of business, our level of 
experience with a particular set of exposures and our analysis of the potential underwriting results. We purchase excess of loss 
reinsurance to limit the amount of risk we retain and we do so from a number of companies to mitigate concentrations of credit 
risk. As of December 31, 2020, there is no reinsurer, on an individual basis, for which our recoverables for both paid and 
unpaid claims (net of amounts due to the reinsurer) and our prepaid balances are aggregately $51 million or more. We utilize 
reinsurance brokers to assist us in the placement of these reinsurance programs and in the analysis of the credit quality of our 
reinsurers. The determination of which reinsurers we choose to do business with is based upon an evaluation of their then 
current financial strength, rating, stability and claims payment practices.

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, 2020, all ceded contracts 
were accounted for as risk transferring contracts.

Our receivable from reinsurers on unpaid losses and loss adjustment expenses represents our estimate of the amount of 

our reserve for losses that will be recoverable under our reinsurance programs. We base our estimate of funds recoverable upon 
our expectation of ultimate losses and the portion of those losses that we estimate to be allocable to reinsurers based upon the 
terms and conditions of our reinsurance agreements. Our assessment of the collectability of the recorded amounts receivable 
from reinsurers considers the payment history of the reinsurer, publicly available financial and rating agency data, our 
interpretation of the underlying contracts and policies and responses by reinsurers.

Given the uncertainty inherent in our estimates of losses and related amounts recoverable from reinsurers, these estimates 

may vary significantly from the ultimate outcome.

Under the terms of certain of our reinsurance agreements, the amount of premium that we cede to our reinsurers is based 

in part on the losses we recover under the agreements. Therefore, we make an estimate of premiums ceded under these 
reinsurance agreements subject to certain minimums and maximums. Any adjustments to our estimates of losses recoverable 
under our reinsurance agreements or the premiums owed under our agreements are reflected in 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 reinsurance receivables are exposed to credit losses but to-date have not experienced any significant amount of 

credit losses. To partially mitigate our exposure to credit losses, reinsurance receivables totaling approximately $96.1 million 
were collateralized by letters of credit or funds withheld as of December 31, 2020. We measure expected credit losses on our 
reinsurance receivables on a collective basis when similar risk characteristics exist or on an individual basis if we determine a 
receivable does not share similar risk characteristics. We measure expected credit losses associated with our reinsurance 
receivables (related to both paid and unpaid losses) at the consolidated level as our reinsurance receivables share similar risk 
characteristics including type of financial asset, type of industry and similar historical and expected credit loss patterns. We 
measure expected credit losses over the average contractual term of our reinsurance receivables utilizing a loss rate method. 
Historical internal credit loss experience is the basis for our assessment of expected credit losses; however, we may also 
consider historical credit loss information from external sources. We also consider reasonable and supportable forecasts of 
future economic conditions in our estimate of expected credit losses. Expected credit losses associated with our reinsurance 
receivables (related to both paid and unpaid losses) were nominal in amount as of December 31, 2020. We had no allowance for 
expected credit losses related to our reinsurance receivables at December 31, 2019. No reinsurance balances were written off 
for credit reasons during the years ended December 31, 2020 or 2019. Should our expected credit loss analysis or other facts or 
circumstances lead us to believe that any reinsurer may not meet its obligations to us, adjustments to the allowance for expected 
credit losses or to reinsurance receivables would be reflected in 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. For further information on our allowance for expected credit 
losses related to our receivables from reinsurers see Note 1 of the Notes to Consolidated Financial Statements.

Investment Valuations

We record the majority of our investments at fair value as shown in the table below. At December 31, 2020, the 

distribution of our investments based on GAAP fair value hierarchies (levels) was as follows:

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 investments are carried at 
fair value. The fair value of our short-term securities approximates the cost of the securities due to their short-term nature.

Because of the number of securities we own and the complexity of developing accurate fair values, we utilize multiple 

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

The pricing services provide a single value per instrument quoted. We review the values provided for reasonableness each 
quarter by comparing market yields generated by the supplied value versus market yields observed in the marketplace. We also 
compare yields indicated by the provided values to appropriate benchmark yields and review for values that are unchanged or 
that reflect an unanticipated variation as compared to prior period values. We utilize a primary pricing service for each security 
type and compare provided information for consistency with alternate pricing services, known market data and information 
from our own trades, considering both values and valuation trends. We also review weekly trades versus the prices supplied by 
the services. If a supplied value appears unreasonable, we discuss the valuation in question with the pricing service and make 
adjustments if deemed necessary. Historically our review has not resulted in any material changes to the values supplied by the 
pricing services. The pricing services do not provide a fair value unless an exchange-traded price or multiple observable inputs 
are available. As a result, the pricing services may provide a fair value for a security in some periods but not others, depending 
upon the level of recent market activity for the security or comparable securities.

Level 1 Investments

Fair values for a majority of our equity securities and portions of our short-term and convertible securities are determined 
using exchange-traded prices. There is little judgment involved when fair value is determined using an exchange-traded price. 
In accordance with GAAP, we classify securities valued using an exchange-traded price as Level 1 securities.

Level 2 Investments

Most fixed income securities do not trade daily; thus, exchange-traded prices are generally not available for these 

securities. However, market information (often referred to as observable inputs or market data, including but not limited to, last 
reported trade, non-binding broker quotes, bids, benchmark yield curves, issuer spreads, two-sided markets, benchmark 
securities, offers and recent data regarding assumed prepayment speeds, cash flow and loan performance data) is available for 
most of our fixed income securities. We determine fair value for a large portion of our fixed income securities using available 
market information. In accordance with GAAP, we classify securities valued based on multiple market observable inputs as 
Level 2 securities. 

Level 3 Investments

When a pricing service does not provide a value for one of our fixed maturity securities, management estimates fair value 

using either a single non-binding broker quote or pricing models that utilize market based assumptions which have limited 
observable inputs. The process involves significant judgment in selecting the appropriate data and modeling techniques to use 
in the valuation process. In accordance with GAAP, we classify securities valued using limited observable inputs as Level 3 
securities.

50

Fair Values Not Categorized

We hold interests in certain investment funds, primarily LPs/LLCs, which measure fund assets at fair value on a recurring 

basis and provide us with a NAV for our interest. As a practical expedient, we consider the NAV provided to approximate the 
fair value of the interest. In accordance with GAAP, we do not categorize these investments within the fair value hierarchy.

Nonrecurring Fair Value Measurements

We measure the fair value of certain assets on a nonrecurring basis when events or changes in circumstances indicate that 

the carrying amount of the asset may not be recoverable. These assets include investments carried principally at cost, 
investments in tax credit partnerships, fixed assets, goodwill and other intangible assets. These assets would also include any 
equity method investments that do not provide a NAV. During the third quarter of 2020, we recognized a nonrecurring fair 
value measurement related to the goodwill in our Specialty P&C reporting unit with a carrying value of $161.1 million prior to 
the fair value measurement. This nonrecurring fair value measurement resulted in the goodwill being written down to its 
implied fair value of zero resulting in an impairment of the goodwill of $161.1 million (see following discussion under the 
heading "Goodwill / Intangibles"). The inputs used in the fair value measurement were non-observable and, as such, were 
categorized as a Level 3 valuation. We did not have any other assets or liabilities that were measured at fair value on a 
nonrecurring basis at December 31, 2020 or December 31, 2019.

Investments - Other Valuation Methodologies

Certain of our investments, in accordance with GAAP for the type of investment, are measured using methodologies other 

than fair value. At December 31, 2020, these investments represented approximately 4% of total investments, and are detailed 
in the following table. Additional information about these investments is provided in Notes 2 and 3 of the Notes to 
Consolidated Financial Statements.

Impairments

We evaluate our available-for-sale investment securities, which at December 31, 2020 and December 31, 2019 consisted 

entirely of fixed maturity securities, on at least a quarterly basis for the purpose of determining whether declines in fair value 
below recorded cost basis represent an impairment loss. We consider a credit-related impairment loss to have occurred:

• if there is intent to sell the security;
• if it is more likely than not that the security will be required to be sold before full recovery of its amortized cost

basis; or

• if the entire amortized basis of the security is not expected to be recovered.

The assessment of whether the amortized cost basis of a security is expected to be recovered requires management to 
make assumptions regarding various matters affecting future cash flows. The choice of assumptions is subjective and requires 
the use of judgment. Actual credit losses experienced in future periods may differ from management’s estimates of those credit 
losses. Methodologies used to estimate the present value of expected cash flows are:

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. We consider various factors in projecting recovery values and recovery 
time frames, including the following:

• 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;

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

issuer;

51

• 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;

• 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;
• adverse legal or regulatory events;
• significant deterioration in the market environment that may affect the value of collateral (e.g. decline in real estate

prices);

• significant deterioration in economic conditions; and
• disruption in the business model resulting from changes in technology or new entrants to the industry.

If deemed appropriate and necessary, a discounted cash flow analysis is performed to confirm whether a credit loss exists 

and, if so, the amount of the credit loss. We use the single best estimate approach for available-for-sale debt securities and 
consider all reasonably available data points, including industry analyses, credit ratings, expected defaults and the remaining 
payment terms of the debt security. For fixed rate available-for-sale debt securities, cash flows are discounted at the security's 
effective interest rate implicit in the security at the date of acquisition. If the available-for-sale debt security’s contractual 
interest rate varies based on subsequent changes in an independent factor, such as an index or rate, for example, the prime rate, 
the LIBOR, or the U.S. Treasury bill weekly average, that security’s effective interest rate is calculated based on the factor as it 
changes over the life of the security. If we intend to sell a debt security or believe we will more likely than not be required to 
sell a debt security before the amortized cost basis is recovered, any existing allowance will be written off against the security's 
amortized cost basis, with any remaining difference between the debt security's amortized cost basis and fair value recognized 
as an impairment loss in earnings.

Exclusive of securities where there is an intent to sell or where it is not more likely than not that the security will be 

required to be sold before recovery of its amortized cost basis, impairment for debt securities is separated into a credit 
component and a non-credit component. The credit component of an impairment is the difference between the security’s 
amortized cost basis and the present value of its expected future cash flows, while the non-credit component is the remaining 
difference between the security’s fair value and the present value of expected future cash flows. An allowance for expected 
credit losses will be recorded for the expected credit losses through income and the non-credit component is recognized in OCI. 
The amount of impairment recognized is limited to the excess of the amortized cost over the fair value of the available-for-sale 
debt security.

Deferred Policy Acquisition Costs

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

the successful acquisition of new and renewal premiums are capitalized as DPAC and charged to expense, net of ceding 
commissions earned, as the related premium revenue is recognized. We evaluate the recoverability of our DPAC typically at the 
segment level each reporting period or in a manner that is consistent with the way we manage our business. Any amounts 
estimated to be unrecoverable are charged to expense in the current period.

As part of our evaluation of the recoverability of DPAC, we also evaluate our unearned premiums for premium 
deficiencies. A premium deficiency is recognized if the sum of anticipated losses and loss adjustment expenses, unamortized 
DPAC and maintenance costs, net of anticipated investment income, exceeds the related unearned premium. If a premium 
deficiency is identified, the associated DPAC is written off, and a PDR is recorded for the excess deficiency as a component of 
net losses and loss adjustment expenses in our Consolidated Statement of Income and Comprehensive Income and as a 
component of the reserve for losses on our Consolidated Balance Sheet. For the year ended December 31, 2020 we did not 
determine any DPAC to be unrecoverable. For the year ended December 31, 2019, a nominal amount of DPAC was charged to 
expense as it was determined to be unrecoverable, and a $9.2 million PDR was established in our Specialty P&C segment 
related to a large national healthcare account. The $9.2 million PDR was fully amortized during 2020. See further discussion on 
the PDR in the Segment Results - Specialty Property & Casualty section that follows.

52

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 our loss reserves, unearned and advanced premiums, DPAC, tax credit carryforwards, 
compensation related items, unrealized investment gains (losses) and basis differences on fixed assets, intangible assets and 
operating leases. 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 of the appropriate character (including its capital and 
operating characteristics) and tax planning strategies.

A valuation allowance was established in a prior year against the deferred tax asset related to the NOL carryforwards for 

the U.K. operations. In addition, a valuation allowance was established in 2020 against a portion of the deferred tax asset 
related to the U.S. state NOL carryforwards. Management concluded that it was more likely than not that these deferred tax 
assets will not be realized. We also established a valuation allowance in a prior year against the deferred tax assets of certain 
SPCs at our wholly owned Cayman Islands reinsurance subsidiary, Inova Re. Due to the limited operations of these SPCs, 
management concluded that a valuation allowance was required. As of December 31, 2020, management concluded that a 
valuation allowance was still required against the deferred tax assets related to the NOL carryforwards for the U.K. operations 
and against the deferred tax assets of certain SPCs at Inova Re. See further discussion in Note 5 of the Notes to Consolidated 
Financial Statements.

Tax Cuts and Jobs Act

The TCJA introduced a minimum tax on payments made to related foreign entities referred to as the BEAT. The BEAT is 

imposed by adding back into the U.S. tax base any base erosion payment made by the U.S. taxpayer to a related foreign entity 
and applying a minimum tax rate to this newly calculated modified taxable income. Base erosion payments represent any 
amount paid or accrued by the U.S. taxpayer to a related foreign entity for which a deduction is allowed. Premiums we cede to 
the SPCs at Inova Re, one of our wholly owned Cayman Islands reinsurance subsidiaries, do not fall within the scope of base 
erosion payments as the SPCs at Inova Re have elected to be taxed as U.S. taxpayers. However, premiums that we cede to any 
active SPC at our other wholly owned Cayman Islands reinsurance subsidiary, Eastern Re, fall within the scope of base erosion 
payments and therefore could be significantly impacted by the BEAT. We have evaluated our exposure to the BEAT and have 
concluded that our expected outbound deductible payments to related foreign entities are below the threshold for application of 
the BEAT; therefore, we have not recognized any incremental tax expense for the BEAT provision of the TCJA during the 
years ended December 31, 2020 or December 31, 2019. See further discussion on our Cayman Islands SPC operations in the 
Segment Results - Segregated Portfolio Cell Reinsurance section that follows. See discussion in Note 5 of the Notes to 
Consolidated Financial Statements.

The TCJA also requires a U.S. shareholder of a controlled foreign corporation to include its GILTI in U.S. taxable 
income. The GILTI amount is based on the U.S. shareholder’s aggregate share of the gross income of the controlled foreign 
corporation reduced by certain exceptions and a net deemed tangible income return. The net deemed tangible income return is 
based on the controlled foreign corporation’s basis in the tangible depreciable business property. Cell rental fee income earned 
by Inova Re and Eastern Re fall within the scope of the GILTI provisions of the TCJA. We have evaluated the new GILTI 
provisions of the TCJA, and we have made an accounting policy election to treat the taxes due on the inclusion of GILTI in 
U.S. taxable income as a current period expense when incurred. We recognized a nominal amount of tax expense for the GILTI 
provision of the TCJA during each of the years ended December 31, 2020 and December 31, 2019. See discussion in Note 5 of 
the Notes to Consolidated Financial Statements.

Coronavirus Aid, Relief and Economic Security Act

In response to COVID-19, the CARES Act was signed into law on March 27, 2020 and contains several provisions for 
corporations and eases certain deduction limitations originally imposed by the TCJA. The CARES Act, among other things, 
includes temporary changes regarding the prior and future utilization of NOLs, temporary changes to the prior and future 
limitations on interest deductions, temporary suspension of certain payment requirements for the employer portion of Social 
Security taxes and the creation of certain refundable employee retention credits. We anticipate the temporary changes regarding 
NOL carryback provisions will have a favorable impact on our liquidity (see discussion that follows in the Liquidity and 
Capital Resources and Financial Condition section under the heading "Taxes"). We have evaluated the other provisions of the 
CARES Act and concluded that they will not have a material impact on our financial position or results of operations. See 
discussion in Note 5 of the Notes to Consolidated Financial Statements.

53

Unrecognized Tax Benefits

We evaluate tax positions taken on tax returns and recognize positions in our financial statements when it is more likely 
than not that we will sustain the position upon resolution with a taxing authority. If recognized, the benefit is measured as the 
largest amount of benefit that has a greater than 50% probability of being realized. We review uncertain tax positions each 
quarter, considering changes in facts and circumstances, such as changes in tax law, interactions with taxing authorities and 
developments in case law, and make adjustments as we consider necessary. Adjustments to our unrecognized tax benefits may 
affect our income tax expense, and settlement of uncertain tax positions may require the use of cash. Other than differences 
related to timing, no significant adjustments were considered necessary during 2020 or 2019. At December 31, 2020, our 
liability for unrecognized tax benefits approximated $5.2 million.

Goodwill / Intangibles

Goodwill is tested for impairment annually or more frequently if circumstances indicate an impairment may have 

occurred. The date of our annual goodwill impairment testing is October 1.

Impairment of goodwill is tested at the reporting unit level, which is consistent with our reportable segments identified in 

Note 16 of the Notes to Consolidated Financial Statements.

During the third quarter of 2020, the Company recorded a goodwill impairment charge of $161.1 million, and the facts 

and circumstances that led to this impairment and how the fair value of each reporting unit was estimated, including the 
significant assumptions used and other details are outlined in the following section.

Interim Impairment Assessments

As disclosed in our June 30, 2020 report on Form 10-Q, COVID-19 has caused significant market volatility impacting our 
actual and projected results along with a decline in our stock price; and we performed a quantitative assessment on the Specialty 
P&C and Workers' Compensation Insurance reporting units. As a result of the interim goodwill impairment assessment in the 
second quarter of 2020, management concluded that the fair value of each of the Specialty P&C and Workers' Compensation 
Insurance reporting units were greater than their carrying value as of the testing date; therefore, goodwill was not impaired and 
no further impairment testing was required at that time. 

As the impacts persisted into the third quarter, management performed new quantitative assessments of goodwill on our 

Specialty P&C and Workers' Compensation Insurance reporting units using updated marketplace data. The updated data, which 
was significantly influenced by our continued depressed stock price relative to both our own book value and the comparable 
stock prices of our peers, impacted a number of key variables in our analysis including the determination of a higher discount 
rate and lower valuation multiples. In addition, new guidance given by the Federal Reserve during the period regarding the 
expectation of a prolonged low interest rate environment impacted our analysis. This analysis during the third quarter of 2020 
indicated an impairment of the goodwill associated with our Specialty P&C reporting unit and accordingly we recorded a 
$161.1 million charge to goodwill during the third quarter of 2020.

For each of the interim impairment assessments performed in the second and third quarters of 2020, management 

estimated the fair value of the reporting units using both an income approach and a market approach using marketplace data that 
was current at the time of each respective analysis. The estimate of fair value derived from the income approach was based on 
the present value of expected future cash flows, including terminal value, utilizing a market-based weighted average cost of 
capital determined separately for each reporting unit. The estimate of fair value derived from the market approach was based on 
price to book multiple data. The determination of fair value involved the use of significant estimates and assumptions, including 
revenue growth rates, operating margins, capital requirements, tax rates, terminal growth rates, discount rates, comparable 
public companies and synergistic benefits available to market participants. In addition, management made certain judgments 
and assumptions in allocating shared assets and liabilities to individual reporting units to determine the carrying amount of each 
reporting unit. 

Management also performed impairment tests of certain of our definite and indefinite lived intangible assets for which a 
triggering event was deemed to have occurred. Based upon these impairment tests, no impairment of our definite or indefinite 
lived intangible assets was identified at September 30, 2020.

Annual Impairment Assessment

Subsequent to performing the interim impairment assessments previously discussed, we performed our annual goodwill 

impairment assessment as of October 1, 2020.

When testing goodwill for impairment on our annual test date, we have the option to first assess qualitative factors to 
determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the 
estimated fair value of a reporting unit is less than its carrying amount. If we elect to perform a qualitative assessment and 
determine that an impairment is more likely than not, we are then required to perform a quantitative impairment test; otherwise, 

54

no further analysis is required. We also may elect not to perform the qualitative assessment and, instead, proceed directly to the 
quantitative impairment test.

Performance of the qualitative goodwill impairment assessment requires judgment in identifying and considering the 

significance of relevant key factors, events, and circumstances that affect the fair values of our reporting units. This requires 
consideration and assessment of external factors such as macroeconomic, industry, and market conditions, as well as entity-
specific factors, such as our actual and planned financial performance. We also give consideration to the difference between 
each reporting unit's fair value and carrying value as of the most recent date that a fair value measurement was performed. If the 
results of the qualitative assessment conclude that it is not more likely than not that the fair value of a reporting unit exceeds its 
carrying value, additional quantitative impairment testing is performed. 

The quantitative goodwill impairment test involves comparing the fair value of a reporting unit with its carrying value 
including goodwill. If the fair value of a reporting unit exceeds its carrying value, the reporting unit's goodwill is considered not 
to be impaired. However, if the carrying value of a reporting unit exceeds its fair value, an impairment loss is recorded in an 
amount equal to that excess. Any impairment charge recognized is limited to the amount of the respective reporting unit's 
allocated goodwill.

Determining the fair value of a reporting unit under the quantitative goodwill impairment test requires judgment and often 
involves the use of significant estimates and assumptions, including an assessment of external factors such as macroeconomic, 
industry, and market conditions, as well as entity-specific factors, such as actual and planned financial performance. These 
estimates and assumptions could have a significant impact on whether or not an impairment charge is recognized and the 
magnitude of any such charge. To assist management in the process of determining any potential goodwill impairment, we may 
review and consider appraisals from accredited independent valuation firms. Estimates of fair value are primarily determined 
using discounted cash flows and market comparisons. These approaches involve significant estimates and assumptions, 
including projected future cash flows (including timing), discount rates reflecting the risks inherent in those future cash flows, 
perpetual growth rates, and selection of appropriate market comparable metrics and transactions.

For the most recent goodwill impairment test performed on October 1, 2020, we elected to perform a qualitative goodwill 

impairment test for our Workers' Compensation Insurance and Segregated Portfolio Cell Reinsurance reporting units. These 
reporting units have historically had an excess of fair value over book value and based on current operations are expected to 
continue to do so; therefore, our annual impairment test for these reporting units was performed qualitatively. In applying the 
qualitative approach, management considered macroeconomic factors, industry and market conditions, cost factors that could 
have a negative impact on the reporting units, actual financial performance of the reporting units versus expectations and 
management's future business expectations. As a result of the qualitative assessments, management concluded that it was not 
more likely than not that the fair value of each of our two reporting units that have net goodwill was less than the carrying value 
of each reporting unit as of the testing date; therefore, no further impairment testing was required. No goodwill impairment was 
recorded during the years ended December 31, 2019 or 2018. See Note 6 of the Notes to Consolidated Financial Statements for 
additional information about our goodwill.

Leases

We are involved in a number of leases, primarily for office facilities. We determine if an arrangement is a lease at the 
inception date of the contract and classify all leases as either financing or operating. As of December 31, 2020, all of our leases 
were classified as operating. Operating lease ROU assets and operating lease liabilities are recognized as of the lease 
commencement date based on the present value of the remaining lease payments, discounted over the term of the lease using a 
discount rate determined based on information available as of the commencement date. The ROU asset represents the right to 
use the underlying asset (office space) for the lease term. As the majority of our lessors do not provide an implicit discount rate, 
we use our collateralized incremental borrowing rate in determining the present value of remaining lease payments. For leases 
entered into or reassessed after the adoption of ASU 2016-02 on January 1, 2019, we account for lease and non-lease 
components of a contract as a single lease component. 

We evaluate our operating lease ROU assets for impairment at the asset group level whenever events or changes in 

circumstances indicate that the carrying amount of the asset group may not be recoverable. The carrying amount of an asset 
group, which includes the operating lease ROU asset and the related operating lease liability, is not recoverable if the carrying 
amount exceeds the sum of the undiscounted cash flows expected to result from the use of the asset group over the life of the 
primary asset in the asset group. That assessment is based on the carrying amount of the asset group, including the operating 
lease ROU asset and the related operating lease liability, at the date it is tested for recoverability, and an impairment loss is 
measured and recognized as the amount by which the carrying amount of the asset group exceeds its fair value. Any impairment 
loss is allocated to each asset in the asset group, including the operating ROU asset.

When a lease of an office facility is to be abandoned and will not be subleased, we first evaluate whether or not the 
operating lease ROU asset’s inclusion in an existing asset group continues to be appropriate and if the commitment to abandon 

55

the lease constitutes a change in circumstances requiring the operating lease ROU asset, or the larger asset group, to be tested 
for impairment. If an impairment test is required, it is performed in the same manner as discussed above. Any remaining 
carrying value of the operating lease ROU asset is amortized from the date we commit to a plan to abandon the lease to the 
expected date that we will cease to use the leased property. Leases to be abandoned in which we have the intent or practical 
ability to sublease continue to be accounted for under a held and use model, with no change to the amortization period of the 
operating lease ROU asset, and are evaluated for impairment as a separate asset group at the date the sublease is executed.

Additional information regarding our leases is included in Note 1 and Note 10 of the Notes to Consolidated Financial 

Statements.

Audit Premium

Workers’ compensation premiums are determined based upon the payroll of the insured, respective premium rates and, 

where applicable, an experience-based modification factor. An audit of the policyholders’ records is conducted after policy 
expiration to make a final determination of applicable premiums. Audit premium due from or due to a policyholder as a result 
of an audit is reflected in net premiums written and earned when billed. We track, by policy, the amount of additional premium 
billed in final audit invoices as a percentage of payroll exposure and use this information to estimate the probable additional 
amount of EBUB as of the balance sheet date. We include changes to the EBUB estimate in net premiums written and earned in 
the period recognized. We reduced our EBUB estimate by $1.3 million during the year ended December 31, 2020 which 
primarily reflected a reduction in earned payroll exposure. As a result of the economic impact of COVID-19, we expect future 
reductions in payroll exposure related to in-force policies that could result in a significant decrease in audit premium and our 
EBUB estimate. We will continue to monitor and adjust the estimate, if necessary, based on changes in insured payrolls and 
economic conditions, as experience develops or new information becomes known; however, the length and magnitude of such 
changes depends on future developments, which are highly uncertain and cannot be predicted. 

Lloyd’s Premium Estimates

For certain insurance policies and reinsurance contracts written in our Lloyd’s Syndicates segment, premiums are initially 

recognized based upon estimates of ultimate premium. Estimated ultimate premium consists primarily of premium written 
under delegated underwriting authority arrangements, which consist primarily of binding authorities, and certain assumed 
reinsurance agreements. These estimates of ultimate premium are judgmental and are dependent upon certain assumptions, 
including historical premium trends for similar agreements. As reports are received from programs, ultimate premium estimates 
are revised, if necessary, with changes reflected in current operations.

Accounting Changes

During the second quarter of 2020, we early adopted ASU 2019-12 which is intended to simplify various aspects related 

to accounting for income taxes. The most impactful provision of the new guidance on the Company is the removal of the 
limitation on the tax benefit recognized on pre-tax losses during interim periods in which the year-to-date loss exceeds the 
expected loss for the fiscal year.

We did not have any other change in accounting estimate or policy that had a material effect on our results of operations 
or financial position during 2020. We are not aware of any accounting changes not yet adopted as of December 31, 2020 that

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. As a 

holding company, our principal source of external revenue is our investment revenues. In addition, dividends from our 
operating subsidiaries represent another source of funds for our obligations, including debt service and shareholder dividends. 
We also charge our operating subsidiaries within our Specialty P&C and Workers' Compensation Insurance segments a 
management fee based on the extent to which services are provided to the subsidiary and the amount of gross premium written 
by the subsidiary. At December 31, 2020, we held cash and liquid investments of approximately $260 million outside our 
insurance subsidiaries that were available for use without regulatory approval or other restriction. We also have $250 million in 
permitted borrowings available under our Revolving Credit Agreement as well as the possibility of a $50 million accordion 
feature if successfully subscribed. As of February 19, 2021, no borrowings were outstanding under our Revolving Credit 
Agreement.

During 2020, our operating subsidiaries paid dividends to us of approximately $118 million, which included extraordinary 

dividends of approximately $64 million. In the aggregate, our insurance subsidiaries are permitted to pay dividends of 
approximately $87 million over the course of 2021 without prior approval of state insurance regulators. However, the payment 
of any dividend requires prior notice to the insurance regulator in the state of domicile, and the regulator may reduce or prevent 
the dividend if, in its judgment, payment of the dividend would have an adverse effect on the surplus of the insurance 
subsidiary. We make the decision to pay dividends from an insurance subsidiary based on the capital needs of that subsidiary 
and may pay less than the permitted dividend or may also request permission to pay an additional amount (an extraordinary 
dividend).

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

The decrease in operating cash flows in 2020 as compared to 2019 of $55.8 million was primarily due to an increase in 

paid losses of $89.1 million driven by our Specialty P&C and Segregated Portfolio Cell Reinsurance segments. The increase in 
paid losses in our Specialty P&C segment was primarily due to higher average claim payments which we believe is an 
indication that the higher severity trends that we are experiencing in our HCPL case reserve estimates are emerging in actual 
claim payments. The increase in paid losses in our Segregated Portfolio Cell Reinsurance segment reflected the payment of a 
$10 million claim during the first quarter of 2020 by an SPC at Eastern Re in which we do not participate. The payment related 
to a reserve established by the SPC in 2019 related to an errors and omissions liability policy. Furthermore, the decrease in 
operating cash flows reflected a decrease in net cash received of $7.4 million associated with the cash settlement of the 2017 
calendar year quota share reinsurance agreement between our Specialty P&C segment and Syndicate 1729 due to the reduction 

57

in premiums ceded to Syndicate 1729. The decrease in operating cash flows also reflected one-time expenses of $5.4 million 
primarily related to employee severance and early retirement benefits paid to certain employees in 2020. Additionally, the 
decrease in operating cash flows reflected a decrease in cash received from investment income of $3.5 million primarily due to 
a reduction in dividends received on our equity portfolio resulting from a decrease in our allocation to this asset category. The 
decrease in operating cash flows was somewhat offset by an increase in net premium receipts of $28.1 million and a decrease in 
2020 net tax payments as compared to 2019 of $9.8 million. The increase in net premium receipts was driven by our Specialty 
P&C segment due to $14.3 million of tail premium received from a large national healthcare account during the second quarter 
of 2020 (see further discussion in our Segment Results - Specialty Property & Casualty section that follows). The decrease in 
net tax payments was primarily due to refunds received in 2020. Furthermore, the decrease in operating cash flows was partially 
offset by an increase in net cash received of $6.8 million associated with the cash settlement of a quota share reinsurance 
agreement between our Specialty P&C segment and one of its reinsurers. The remaining variance in operating cash flows in 
2020 as compared to 2019 was comprised of individually insignificant components.

The decrease in operating cash flows in 2019 as compared to 2018 of $29.1 million was primarily due to an increase in 
paid losses of $30.2 million, a decrease in cash received from investment income of $9.8 million and an increase in cash paid 
for operating expenses of $8.1 million. The increase in paid losses was driven by our Specialty P&C and Workers' 
Compensation Insurance segments. The increase in paid losses in our Specialty P&C segment primarily reflected higher 
average claims payments in 2019 as compared to 2018 and the increase in paid losses in our Workers' Compensation Insurance 
segment primarily reflected the timing of loss payments between periods. The decrease in cash received from investment 
income was primarily due to a decline in distributed earnings from our unconsolidated subsidiaries. The increase in cash paid 
for operating expenses was driven by an increase in brokerage expenses in our Lloyd's Syndicates segment from the continuing 
growth of Syndicate 6131 as well as an increase in fees associated with a data analytics services agreement entered into during 
the fourth quarter of 2018 in our Specialty P&C segment. In addition, the decrease in operating cash flows reflected a decrease 
in net cash received of $3.0 million associated with the cash settlement from the commutation of the 2017 and 2016 calendar 
year quota share reinsurance agreements between our Specialty P&C segment and Syndicate 1729 due to the reduction in 
premiums ceded to Syndicate 1729. The decrease in operating cash flows was partially offset by an increase in net premium 
receipts of $19.0 million and a decrease in estimated tax payments of $3.0 million. The increase in net premium receipts was 
primarily due to the growth in written premium in our Lloyd's Syndicates and Specialty P&C segments.

We manage our investing cash flows 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 as discussed in this section under the heading "Investing 
Activities and Related Cash Flows."

Our financing cash flows are primarily composed of dividend payments and borrowings and repayments under our 

Revolving Credit Agreement. See further discussion of our financing activities in this section under the heading "Financing 
Activities and Related Cash Flows."

Operating Activities and Related Cash Flows

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, we have completed various acquisitions over the ten year period which have affected original and re-
estimated gross and net reserve balances as well as loss payments.

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

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

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 Balance Sheets
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 the remaining net
liability based upon claims experience as of the end of each succeeding year (the Net Re-estimated Liability).
The line entitled “Net cumulative redundancy (deficiency)” reflects the difference between the previously recorded
Balance Sheet Reserve for each applicable year and the Net Re-estimated Liability relating thereto as of the end of the
most recent fiscal year.

Table Notes

•

•

•

Reserves for 2010 and thereafter include gross and net reserves acquired in 2010 business combinations of
$88.1 million and $82.2 million, respectively.

Reserves for 2012 and thereafter include gross and net reserves acquired in 2012 business combinations of
$21.8 million and $19.2 million, respectively, which considers reductions of $3.6 million and $3.3 million,
respectively, recorded in 2013 due to the re-estimation of the fair value of the acquired reserves.

Reserves for 2013 include gross and net reserves acquired in 2013 business combinations of $201.1 million and
$126.0 million, respectively.

Reserves for 2014 include gross and net reserves acquired in 2014 business combinations of $153.2 million and
$139.5 million, respectively.

In each year reflected in the table, we have estimated our reserve for losses utilizing the management and actuarial 

processes discussed under the heading "Reserve for Losses and Loss Adjustment Expenses" in the Critical Accounting 
Estimates section. 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 HCPL legal environment deteriorated in the late 1990’s and severity began to increase at a greater pace than
anticipated in our rates and reserve estimates. We addressed the adverse severity trends through increased rates, stricter
underwriting and modifications to claims handling procedures, and reflected this adverse severity trend when we
established our initial reserves for subsequent years.
These adverse severity trends later moderated, with that moderation becoming more pronounced beginning in 2009.
We were cautious in giving full recognition to indications that the pace of severity increase had slowed, however we
gave measured recognition of the improved trend in our reserve estimates. The favorable development was most
pronounced for years 2004 to 2008, as the initial reserves for these accident years were established prior to substantial
indication that severity trends were moderating. We gave stronger recognition to the lower severity trend as time
elapsed and a greater percentage of claims were closed.

A general decline in claims frequency has also been a contributor to favorable loss development. A significant portion
of our policies through 2003 were issued on an occurrence basis, and a smaller portion of our ongoing business results
from the issuance of extended reporting endorsements which have occurrence-like exposure. As claims frequency
declined, the number of reported claims related to these coverages was less than originally expected.

Beginning in 2017, we identified potential higher severity trends in the broader HCPL industry. These trends were also
reflected in increases in estimates of ultimate losses for open HCPL claims for earlier accident years, which resulted in
a lower amount of favorable development recognized in 2018 and 2017 as compared to prior years.

During 2019 the loss experience in our Specialty line of business deteriorated further, particularly in regard to the
reserves we established for a large national healthcare account that has experienced losses far exceeding the
assumptions we made when underwriting the account, beginning in 2016. As a result, we strengthened our Specialty
reserves through the recognition of net unfavorable development on prior accident years and a higher current accident
year net loss ratio in our Specialty P&C segment in 2019 as discussed more fully in our Segment Results - Specialty
Property and Casualty section that follows.

(1) Current  year  net  losses  for  the  year  ended  December  31,  2019  included  incurred  losses  of  $2.1  million  related  to  a  loss
portfolio transfer entered into during 2019 in the Specialty P&C segment. Current year net losses in 2018 included incurred
losses  of  $25.4  million  related  to  a  loss  portfolio  transfer  entered  into  during  the  second  quarter  of  2018  (see  Note  8  of  the
Notes to Consolidated Financial Statements).

(2) Current year net losses for the year ended December 31, 2019 included a PDR of $9.2 million associated with the unearned
premium of a large national healthcare account's claims-made policy in the Specialty P&C segment. Current year net losses for
the year ended December 31, 2020 included the amortization of the aforementioned $9.2 million PDR which offsets the impact
of the losses incurred associated with the premium earned related to the large national healthcare account's claims-made policy.
For additional information regarding the PDR see Note 7 of the Notes to Consolidated Financial Statements.

(3) During  2020,  the  aforementioned  large  national  healthcare  account  did  not  renew  on  terms  offered  by  us  and  exercised  its
contractual option to purchase extended reporting endorsement or "tail" coverage. As a result, we recognized total current year
losses of $60.0 million (assumes a full limit loss) within the Specialty P&C segment for the year ended December 31, 2020
(see Note 8 of the Notes to Consolidated Financial Statements).

At December 31, 2020 our gross reserve for losses included case reserves of approximately $1.4 billion and IBNR 
reserves of approximately $1.0 billion. Our consolidated gross reserve for losses on a GAAP basis exceeds the combined gross 
reserves of our insurance subsidiaries on a statutory basis by approximately $0.2 billion, which is principally due to the portion 
of the GAAP reserve for losses that is reflected for statutory accounting purposes as unearned premiums. These unearned 
premiums are applicable to extended reporting endorsements (“tail” coverage) issued without a premium charge upon death, 
disability or retirement of an insured who meets certain qualifications.

Reinsurance

Within our Specialty P&C segment, we use insurance and reinsurance (collectively, “reinsurance”) to provide capacity to 

write larger limits of liability, to provide reimbursement for losses incurred under the higher limit coverages we offer and to 
provide protection against losses in excess of policy limits. Within our Workers' Compensation Insurance segment, we use 
reinsurance to reduce our net liability on individual risks, to mitigate the effect of significant loss occurrences (including 
catastrophic events), to stabilize underwriting results and to increase underwriting capacity by decreasing leverage. In both our 
Specialty P&C and Workers' Compensation Insurance segments, we use reinsurance in risk sharing arrangements to align our 
objectives with those of our strategic business partners and to provide custom insurance solutions for large customer groups. 
The purchase of reinsurance does not relieve us from the ultimate risk on our policies; however, it does provide reimbursement 
for certain losses we pay. We pay our reinsurers a premium in exchange for reinsurance of the risk. In certain of our excess of 
loss arrangements, the premium due to the reinsurer is determined by the loss experience of the business reinsured, subject to 
certain minimum and maximum amounts. Until all loss amounts are known, we estimate the premium due to the reinsurer. 

62

Changes to the estimate of premium owed under reinsurance agreements related to prior periods are recorded in the period in 
which the change in estimate occurs and can have a significant effect on net premiums earned.

We offer alternative market solutions whereby we cede certain premiums from our Workers' Compensation Insurance and 

Specialty P&C segments to either the SPCs at Inova Re or Eastern Re, our Cayman Islands reinsurance subsidiaries which are 
reported in our Segregated Portfolio Cell Reinsurance segment, or, to a limited extent, an unaffiliated captive insurer for one 
program. For the years ended December 31, 2020 and 2019, we wrote total alternative market premium of approximately $76.6 
million and $90.0 million, respectively. The majority of these policies ($72.8 million and $86.7 million of premium in 2020 and 
2019, respectively) are reinsured to the SPCs at Inova Re or Eastern Re, net of a ceding commission. Each SPC at Inova Re and 
Eastern Re is owned, fully or in part, by an agency, group or association, and the results of the SPCs are due to the participants 
of that cell. We participate to a varying degree in the results of selected SPCs and, for the SPCs in which we participate, our 
participation interest ranges from a low of 20% to a high of 85%. SPC results attributable to external cell participants are 
reflected as an SPC dividend expense (income) in our Segregated Portfolio Cell Reinsurance segment. See further discussion on 
our SPC operations in the Segment Results - Segregated Portfolio Cell Reinsurance section that follows. The alternative market 
workers' compensation policies are ceded from our Workers' Compensation Insurance segment to the SPCs under 100% quota 
share reinsurance agreements. The alternative market healthcare professional liability policies are ceded from our Specialty 
P&C segment to the SPCs under either excess of loss or quota share reinsurance agreements, depending on the structure of the 
individual program. The nominal portion of the risk that is not ceded to an SPC is retained in our Specialty P&C segment and 
may also be reinsured under our standard healthcare professional liability reinsurance program, depending on the policy limits 
provided. The remaining premium written in our alternative market business of $2.8 million and $2.4 million in 2020 and 2019, 
respectively, was 100% ceded to an unaffiliated captive insurer.

Excess of Loss Reinsurance Agreements

We generally reinsure risks under treaties (our excess of loss reinsurance agreements) pursuant to which the reinsurers 

agree to assume all or a portion of all risks that we insure above our individual risk retention levels, up to the maximum 
individual limits offered. Generally, these agreements are negotiated and renewed annually. Our HCPL treaty renews annually 
on October 1 and, for the October 1, 2020 renewal, we increased our retention to $2 million from $1 million and added 
provisions for reinstatement premiums which resulted in a reduction to the gross rate paid under the renewed treaty. 
Historically, our Medical Technology Liability treaty renewed annually on January 1; however, the treaty that renewed on 
January 1, 2020 renewed on a short-term basis and was renewed again for a full year term on October 1, 2020 along with our 
HCPL treaty. Our Medical Technology Liability treaty which renewed on October 1, 2020 renewed at a lower rate than the 
previous agreement, with an increase in retention to $2 million from $1 million. Our Workers' Compensation treaty renews 
annually on May 1. Our traditional workers' compensation treaty renewed May 1, 2020 at a higher rate than the previous 
agreement, with an increase in the AAD to 3.16% from 2.1% of subject earned premium, in excess of the $0.5 million retention 
per loss occurrence; all other material treaty terms were consistent with the expiring agreement. The significant coverages 
provided by our current excess of loss reinsurance agreements are detailed in the following table.

63

Excess of Loss Reinsurance Agreements

Healthcare 
Professional Liability

Medical Technology &
Life Sciences Products

Workers' 
Compensation - Traditional

(1) Effective October 1, 2020, one prepaid limit reinstatement of $21M and a second limit reinstatement
of up to $21M for the second layer, subject to reinstatement premium, which attaches after the first
reinstatement has been completely exhausted. All limit reinstatements thereafter require no additional
premium.

(2) Prior to October 1, 2020, retention has been $1M.
(3) Historically, retention has ranged from 5% to 32.5%.
(4) Historically, retention has ranged from $1M to $2M.
(5) Includes  an  AAD  where  retention  is  3.16%  of  subject  earned  premium  in  annual  losses  otherwise

recoverable in excess of the $500K retention per loss occurrence.

Large HCPL risks that are above the limits of our basic reinsurance treaties are reinsured on a facultative basis, whereby 

the reinsurer agrees to insure a particular risk up to a designated limit. We also have in place a number of risk sharing 
arrangements that apply to the first $2 million of losses for certain large healthcare systems and other insurance entities, as well 
as with certain insurance agencies that produce business for us.

Other Reinsurance Arrangements

For the workers' compensation business ceded to Inova Re and Eastern Re, each SPC has in place its own reinsurance 

arrangements; which are illustrated in the following table. 

Segregated Portfolio Cell Reinsurance

Per Occurrence Coverage

Aggregate Coverage

(1) The attachment point is based on a percentage of written premium within individual

cells (average is 89%) and varies by cell.

Each SPC has participants and the profit or loss of each cell accrues fully to these cell participants. As previously 
discussed, we participate in certain SPCs to a varying degree. Each SPC maintains a loss fund initially equal to the difference 
between premium assumed by the cell and the ceding commission. The external participants of each cell provide collateral to 
us, typically in the form of a letter of credit, that is initially equal to the difference between the loss fund of the SPC (amount of 
funds available to pay losses after deduction of ceding commission) and the aggregate attachment point of the reinsurance. Over 
time, an SPC's retained profits are considered in the determination of the collateral amount required to be provided by the cell's 
external participants. 

Within our Lloyd's Syndicates segment, Syndicate 1729 utilizes reinsurance to provide capacity to write larger limits of 

liability on individual risks, to provide protection against catastrophic loss and to provide protection against losses in excess of 
policy limits. The level of reinsurance that Syndicate 1729 purchases is dependent on a number of factors, including its 
underwriting risk appetite for catastrophic exposure, the specific risks inherent in each line or class of business written and the 
pricing, coverage and terms and conditions available from the reinsurance market. Reinsurance protection by line of business is 
as follows:

• Reinsurance is utilized on a per risk basis for the property insurance and casualty coverages in order to mitigate risk

volatility.

• Catastrophic protection is utilized on both our property insurance and casualty coverages to protect against losses in

excess of policy limits as well as natural catastrophes.

• Both quota share reinsurance and excess of loss reinsurance are utilized to manage the net loss exposure on our

property reinsurance coverages.

• Property umbrella excess of loss reinsurance is utilized for peak catastrophe and frequency of catastrophe

exposures.

65

• External excess of loss reinsurance is utilized by Syndicate 1729 to manage the net loss exposure on the specialty
property and contingency coverages ceded to Syndicate 6131. For the second half of 2020, external quota share
reinsurance was utilized by Syndicate 6131 to manage the net loss exposure on the specialty property and
contingency coverages it assumed from Syndicate 1729 by ceding essentially half of the premium assumed to an
unaffiliated insurer; this agreement was non-renewed on January 1, 2021 (see further discussion in the Segment
Results - Lloyd's Syndicates section that follows).

Syndicate 1729 may still be exposed to losses that exceed the level of reinsurance purchased as well as to reinstatement 

premiums triggered by losses exceeding specified levels. Cash demands on Syndicate 1729 can vary significantly depending on 
the nature and intensity of a loss event. For significant reinsured catastrophe losses, the inability or unwillingness of the 
reinsurer to make timely payments under the terms of the reinsurance agreement could have an adverse effect on Syndicate 
1729's liquidity.

Taxes

We are subject to the tax laws and regulations of the U.S., Cayman Islands and U.K. We file a consolidated U.S. federal 

income tax return that includes the parent company and its U.S. subsidiaries. Our filing obligations include a requirement to 
make quarterly payments of estimated taxes to the IRS using the corporate tax rate effective for the tax year. We did not make 
any quarterly estimated tax payments during the year ended December 31, 2020.

As a result of the CARES Act that was signed into law on March 27, 2020, as previously discussed, we now have the 
ability to carryback NOLs generated in tax years 2018, 2019 and 2020 for up to five years. We have an NOL of approximately 
$45.3 million from the 2020 tax year that will be carried back to the 2015 tax year and is expected to generate a tax refund of 
approximately $15.9 million. Additionally, we had an NOL of approximately $25.6 million from the 2019 tax year which was 
carried back to the 2014 tax year and generated a tax refund of approximately $9.0 million which we received in February 
2021. Furthermore, our effective tax rate for the year ended December 31, 2020 was affected by the tax rate differential on the 
carryback of the 2020 and 2019 NOLs to the 2015 and 2014 tax years, respectively, when the federal statutory tax rate was 35% 
as compared to the current tax rate of 21%. See further discussion on our effective tax rate for the year ended December 31, 
2020 in the Segment Results - Corporate section that follows under the heading "Taxes." We have evaluated the other 
provisions of the CARES Act and concluded that they will not have a material impact on our financial position or results of 
operations. See further discussion in Note 5 of the Notes to Consolidated Financial Statements.

Litigation

We are involved in various legal actions related to insurance policies and claims handling including, but not limited to, 

claims asserted against us by policyholders. These types of legal actions arise in the ordinary course of business and, in 
accordance with GAAP for insurance entities, are generally considered as a part of our loss reserving process, which is 
described in detail in our Critical Accounting Estimates section under the heading "Reserve for Losses and Loss Adjustment 
Expenses." We also have other direct actions against the Company unrelated to our claims activity which we evaluate and 
account for as a part of our other liabilities. For these corporate legal actions, we evaluate each case separately and establish 
what we believe is an appropriate reserve based on GAAP guidance related to contingent liabilities. As of December 31, 2020 
there were no material reserves established for corporate legal actions.

A detailed listing of our investment holdings as of December 31, 2020 is located under the Financial Information heading 

on the Investor Relations page of our website which can be reached directly at www.proassurance.com/investmentholdings or 
through links from the Investor Relations section of our website, investor.proassurance.com.

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. During the year ended December 31, 2020, we received and 
granted requests for premium relief for certain insureds that have been adversely impacted by the recent COVID-19 pandemic 
in the form of either premium credits or premium deferrals. While premium credits and deferrals granted during the year ended 
December 31, 2020 did not have a significant impact on our liquidity, additional premium relief efforts could have an impact on 
our cash flows to be generated from our operations in future quarters and could result in an increase to our allowance for 
expected credit losses related to our premiums receivable. In addition to the interest and dividends we will receive from our 
investments, we anticipate that between $50 million and $110 million of our portfolio will mature (or be paid down) each 
quarter over the next twelve months 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 with consideration to current and anticipated industry trends and macroeconomic conditions, 
including the impacts of COVID-19. To the extent that we may have an unanticipated shortfall in cash, we may either liquidate 
securities or borrow funds under existing borrowing arrangements through our Revolving Credit Agreement and the FHLB 
system. Permitted borrowings under our Revolving Credit Agreement are $250 million with the possibility of an additional $50 
million accordion feature, if successfully subscribed. Given the duration of our investments, we do not foresee a shortfall that 
would require us to meet operating cash needs through additional borrowings. Additional information regarding our Revolving 
Credit Agreement is detailed in Note 11 of the Notes to Consolidated Financial Statements.

At December 31, 2020, our FAL was comprised of fixed maturity securities with a fair value of $95.0 million and cash 

and cash equivalents of $11.2 million deposited with Lloyd's. See further discussion in Note 3 of the Notes to Consolidated 
Financial Statements. During the third quarter of 2020, we received a return of approximately $32.3 million of FAL given the 
reduction in our participation in the results of Syndicate 1729 for the 2020 underwriting year to 29% from 61%. 

Our investment portfolio continues to be primarily composed of high quality fixed income securities with approximately 
94% 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, 2020 was 3.16 years; the weighted average effective duration 
of our fixed maturity securities combined with our short-term securities was 2.78 years.

(1) The  carrying  value  reflects  our  total  commitments  (both  funded  and  unfunded)  to  the  partnerships,  less  any  amortization,  since  our

initial investment. We fund these investments based on funding schedules maintained by the partnerships.

(2) The carrying value reflects our funded commitments less any amortization.

Investment fund LPs/LLCs are by nature less liquid and may involve more risk than other investments. We manage our
risk through diversification of asset class and geographic location. At December 31, 2020, we had investments in 31 separate 
investment funds with a total carrying value of $282.8 million which represented approximately 8% of our total investments. 
Our investment fund LPs/LLCs generate earnings from trading portfolios, secured debt, debt securities, multi-strategy funds 
and private equity investments, and the performance of these LPs/LLCs is affected by the volatility of equity and credit 
markets. For our investments in LPs/LLCs, we record our allocable portion of the partnership operating income or loss as the 
results of the LPs/LLCs become available, typically following the end of a reporting period.

Acquisitions

We have entered into a definitive agreement to acquire NORCAL, an underwriter of medical professional liability 
insurance, subject to the demutualization of NORCAL Mutual, NORCAL's ultimate controlling party. Upon satisfaction of the 
various remaining regulatory approvals required, we are anticipating to close the transaction in the second quarter of 2021. 
Subject to NORCAL’s conversion from a mutual company to a stock company, we have agreed to acquire 100% of the 
converted company stock in exchange for base consideration of $450 million and contingent consideration of up to an 
additional $150 million depending on the development of NORCAL’s ultimate losses over a three-year period following the 
acquisition date. The actual final cost of the transaction could vary due to the ability of NORCAL’s policyholders to elect forms 
of consideration other than stock in the demutualization transaction as provided by California law. Those alternative 
consideration options are tied to an appraised value of NORCAL as determined by the California insurance regulator rather than 
the price per share we have agreed to pay for 100% of NORCAL assuming that all policyholders elect to receive stock. Further, 
the transaction is subject to a number of closing conditions, including a maximum threshold for one of the alternative forms of 
consideration in the demutualization, a minimum threshold for the number of NORCAL shares tendered to us, and various 
required regulatory approvals, as previously mentioned. The Agreement and Plan of Acquisition is included as Exhibit 10.19 of 
this report. We plan to utilize our Revolving Credit Agreement to partially finance the acquisition (see further discussion on our 
Revolving Credit Agreement in this section under the heading "Debt"). The COVID-19 pandemic’s potential disruption to our 
business operations may require us to access our Revolving Credit Agreement for other purposes including working capital, 
capital expenditures or other general corporate requirements. If needed, we may be required to obtain additional financing and 
our ability to arrange such financing or refinancing will depend on, among other factors, our financial position and 
performance, as well as prevailing market conditions and other factors beyond our control. As a result, we may be compelled to 
take additional measures to preserve our cash flow, including the reduction of operating expenses or reduction or suspension of 
dividend payments, at least until the impacts of the COVID-19 pandemic improve. We believe that funds available under the 
Revolving Credit Agreement, along with cash generated from our operations and investment portfolio, will be sufficient to meet 
our liquidity needs.

Each dividend was paid in the month following the quarter in which it was declared. Cash dividends totaling $39 million, 

$93 million and $316 million were paid during the years ended December 31, 2020, 2019 and 2018, respectively. Given our 
current earnings profile, the effects that underlying conditions in the broader insurance marketplace continue to have on our 
results and the uncertainties introduced by the COVID-19 pandemic, our Board made the decision to reduce our quarterly cash 
dividend from $0.31 per share to $0.05 per share, beginning with the dividend that was declared during the second quarter of 
2020. Any decision to pay future cash dividends is subject to the Board’s final determination after a comprehensive review of 
financial performance, future expectations and other factors deemed relevant by the Board.

Debt

At December 31, 2020, our debt included $250 million of outstanding unsecured senior notes. The notes bear interest at 
5.3% annually and are due in 2023 although they may be redeemed in whole or part prior to maturity. There are no financial 
covenants associated with these notes.

We have a Revolving Credit Agreement, which expires in November 2024, that may be used for general corporate 

purposes, including, but not limited to, short-term working capital, share repurchases as authorized by the Board and support for 
other activities, such as the planned acquisition of NORCAL, as previously discussed under the heading "Acquisitions." Our 
Revolving Credit Agreement permits borrowings of up to $250 million as well as the possibility of a $50 million accordion 
feature, if successfully subscribed. At December 31, 2020, there were no outstanding borrowings on our Revolving Credit 
Agreement; we are in compliance with the financial covenants of the Revolving Credit Agreement.

We have Mortgage Loans with one lender in connection with the recapitalization of two office buildings, which mature in 
December 2027. The Mortgage Loans accrue interest at three-month LIBOR plus 1.325% with principal and interest payable on 
a quarterly basis. At December 31, 2020, the outstanding balance of the Mortgage Loans was approximately $36 million; we 
are in compliance with the financial covenant of the Mortgage Loans.

Additional information regarding our debt is provided in Note 11 of the Notes to Consolidated Financial Statements.

We utilize an interest rate cap agreement with a notional amount of $35 million to manage our exposure to increases in 
LIBOR on our Mortgage Loans. Per the interest rate cap agreement, we are entitled to receive cash payments if and when the 
three-month LIBOR exceeds 2.35%. Additional information on our interest rate cap agreement is provided in Note 11 of the 
Notes to Consolidated Financial Statements.

Two of our insurance subsidiaries are members of an FHLB. Through membership, those subsidiaries have access to 

secured cash advances which can be used for liquidity purposes or other operational needs. In order for us to use FHLB 
proceeds, regulatory approvals may be required depending on the nature of the transaction. To date, those subsidiaries have not 
materially utilized their membership for borrowing purposes.

segment (see further discussion under the heading "Expenses" in this section and in our Segment Results - Specialty Property & 
Casualty section that follows). Consolidated net premiums earned for the year ended December 31, 2019 included $2.7 million 
of premium written and fully earned from a loss portfolio transfer entered into during the third quarter of 2019 in our Specialty 
P&C segment (see further discussion in our Segment Results - Specialty Property & Casualty section that follows). Excluding 
the impact of the large national healthcare account's tail policy premium and the 2019 loss portfolio transfer, consolidated net 
premiums earned decreased $66.4 million during 2020 as compared to 2019. All of our operating segments contributed to the 
remaining decrease in consolidated net premiums earned, particularly our Specialty P&C segment due to our re-underwriting 
efforts as we continue to emphasize careful risk selection, rate adequacy and a willingness to walk away from business that does 
not fit our goal of achieving a long-term underwriting profit. For our Workers' Compensation Insurance and Segregated 
Portfolio Cell Reinsurance segments, the decrease in net premiums earned primarily reflected the competitive workers' 
compensation market conditions and, for the Segregated Portfolio Cell Reinsurance segment, the reduction in premium funding 
for a large workers' compensation alternative market program. The decrease in net premiums earned in our Lloyd's Syndicates 
segment was driven by our decreased participation in the results of Syndicate 1729 for the 2020 underwriting year to 29% from 
61%.

The decrease in our consolidated net investment result for the year ended December 31, 2020 as compared to 2019 was 
driven by a decrease in our allocation to equities and lower yields on our short-term investments and corporate debt securities 
given the actions taken by the Federal Reserve to aggressively reduce interest rates in response to COVID-19. Equity in 
earnings (loss) of unconsolidated subsidiaries includes our share of the operating results of interests we hold in certain LPs/
LLCs as well as operating losses associated with our tax credit partnership investments, which are designed to generate returns 
in the form of tax credits and tax-deductible project operating losses. The decrease in our equity in earnings (loss) of 
unconsolidated subsidiaries in 2020 as compared to 2019 was due to lower reported earnings from several LPs/LLCs driven by 

72

the volatility in the global financial markets related to COVID-19, partially offset by lower tax credit partnership operating 
losses.

For the year ended December 31, 2020, we recognized $1.5 million of credit-related impairment losses in earnings and a 

nominal amount of non-credit impairment losses in OCI. The credit-related impairment losses recognized in 2020 primarily 
related to corporate bonds in the energy and consumer sectors. Additionally, 2020 included credit-related impairment losses 
related to four corporate bonds in various sectors, which were sold in 2020. The non-credit impairment losses recognized during 
2020 related to three corporate bonds in the energy and consumer sectors. We recognized credit-related impairment losses in 
earnings of $0.8 million and nominal amount of non-credit impairment losses in OCI during 2019, both of which related to 
three corporate bonds in the energy and consumer sectors. 

We recognized $17.2 million of consolidated other net realized investment gains in 2020, driven by realized gains on the 
sale of our available-for-sale fixed maturities and equity investments which were partially offset by unrealized holding losses 
resulting from decreases in the fair value on our equity portfolio due to the volatility in the global financial markets related to 
COVID-19. Consolidated other net realized investment gains recognized in 2019 reflected both realized gains from the sale of 
equity investments and unrealized holdings gains on our equity portfolio due to the improvement in the market since 
December 31, 2018, which caused our equity securities to increase in value. See further discussion in our Segment Results - 
Corporate section that follows.

The primary drivers of the change in our consolidated current accident year net loss ratio for the year ended December 31,

Our consolidated current accident year net loss ratio in 2020 and 2019 was impacted by a large national healthcare 
account. In 2019, we increased our reserve estimates in our Specialty P&C segment for this account's claims-made policy based 
on our in-depth review of our current accident year reserve which we believed best reflected emerging data at that time. In 
addition, we recognized a PDR of $9.2 million during the fourth quarter of 2019 related to this account which increased current 
accident year net losses. The PDR represented an estimated premium deficiency associated with the unearned premium of this 
account's claims-made policy as of the end of 2019. During 2020, this PDR was amortized back into current accident year net 
losses which offset the impact of the losses incurred in 2020 associated with the earned premium related to this account's 
claims-made policy. During the second quarter of 2020, the policy term associated with this account's claims-made policy 
expired. This account did not renew on terms offered by us and the insured exercised its contractual option to purchase the 
extended reporting endorsement or "tail" coverage resulting in a net underwriting loss of $45.7 million in our Specialty P&C 
segment during the second quarter of 2020. The net impact of this large national healthcare account resulted in a 2.0 percentage 
point increase in our consolidated current accident year net loss ratio in 2020 as compared to 2019. See further discussion on 
the large national healthcare account in our Segment Results - Specialty Property & Casualty section that follows. Also during 
the second quarter of 2020, we established a $10 million reserve in our Specialty P&C segment for COVID-19 which increased 
our current accident year net loss ratio by 1.3 percentage points in 2020 (see further discussion in our Segment Results - 
Specialty Property & Casualty section that follows). In addition, our consolidated current accident year net loss ratio in 2019 
included the impact of an increase to our reserve in our Specialty P&C segment related to DDR coverage endorsements which 
accounted for 0.8 percentage points of the decrease in the 2020 ratio as compared to 2019. Furthermore, our consolidated 
current accident year net loss ratio in 2019 was affected by a $10 million reserve established by an SPC at Eastern Re 
associated with an assumed E&O liability policy which accounted for 1.2 percentage points of the decrease in our consolidated 
current accident year net loss ratio in 2020 as compared to 2019 (see further discussion in our Segment Results - Segregated 
Portfolio Cell Reinsurance section that follows). Excluding the impacts of the previously discussed items, our consolidated 
current accident year net loss ratio decreased 1.8 percentage points in 2020 as compared to 2019. This remaining decrease was 
driven by a lower current accident year net loss ratio in our Specialty P&C segment primarily due to decreases in certain loss 
ratios in 2020 in our Standard Physician, Specialty and Small Business Unit lines as a result of our re-underwriting efforts and 
focus on rate adequacy (see further discussion in our Segment Results - Specialty P&C section that follows).

In both 2020 and 2019, our consolidated calendar year net loss ratio was lower than our consolidated current accident year 

net loss ratio due to the recognition of consolidated net favorable prior year reserve development, as shown in the previous 
table. Consolidated net favorable prior year reserve development recognized in 2019 included $51.5 million of unfavorable 
prior year reserve development in our Specialty P&C segment related to the previously mentioned large national healthcare 
account that has experienced losses far exceeding the assumptions we made when underwriting the account, beginning in 2016. 
Excluding the unfavorable development related to the large national healthcare account in 2019, our consolidated net favorable 
prior year reserve development was $12.9 million lower as compared to 2019 driven by our Specialty P&C segment given our 
concerns around elevated loss severity in the broader medical professional liability industry, including our Specialty line of 
business, and the possibility of delays in reporting and uncertainty surrounding the length and severity of the COVID-19 
pandemic. In both our Specialty P&C and Workers' Compensation Insurance segments, we have observed a reduction in claims 
frequency as compared to 2019, some of which is likely associated with the COVID-19 pandemic. As it relates to our Workers' 
Compensation Insurance segment, legislative and regulatory bodies in certain states have changed or are attempting to change 
compensability requirements and presumptions for certain types of workers related to COVID-19 claims. These endeavors 
could have an adverse impact on the frequency and severity related to COVID-19 claims. Furthermore, as it relates to both our 
Workers' Compensation Insurance and Segregated Portfolio Cell Reinsurance segments, the current economic conditions 
resulting from the COVID-19 pandemic have introduced significant risk of a prolonged recession, which could have an adverse 
impact on our return to wellness efforts and the ability of injured workers to return to work, resulting in a potential reduction in 
favorable claim trends in future periods.

underwriting  expense  ratio  in  2019  included  a  provision  for  U.S.  federal  income  taxes  of  $1.1  million  for  certain
SPCs  at  Inova  Re.  Beginning  in  2020,  this  tax  provision  is  now  presented  as  a  separate  line  on  our  Consolidated

(2) See previous discussion under the heading "Revenues"

Our consolidated underwriting expense ratio in 2020 was impacted by a decline in consolidated net premiums earned 
which outpaced the decline in consolidated DPAC amortization, accounting for 2.0 percentage points of the increase in the 
ratio, driven by lower earned premium in our Specialty P&C and Workers' Compensation Insurance segments. Our consolidated 
underwriting expense ratio also reflected one-time expenses of $5.4 million in 2020 mainly comprised of early retirement 
benefits granted to certain employees and expenses associated with the restructuring of our HCPL field office organization. In 
addition, our consolidated underwriting expense ratio was impacted by an increase in professional fees in our Corporate 
segment associated with our planned acquisition of NORCAL as well as corporate legal expenses. The remaining decrease in 
our consolidated underwriting expense ratio in 2020 of 2.2 percentage points primarily reflected the impact of a decrease in 
various operational expenses resulting from incremental improvements over the past year in our Specialty P&C segment 
including organizational structure enhancements and improved operating efficiencies. In addition, the remaining decrease in our 
consolidated underwriting expense ratio reflected lower operating expenses in our Lloyd's Syndicates segment due to our 
reduced participation in Syndicate 1729, lower consolidated travel-related costs due to COVID-19 and, to a lesser extent, a 
reduction of $1.7 million in employer contributions to the ProAssurance Savings Plan (see further discussion in Note 17 of the 
Notes to Consolidated Financial Statements).

We recognized an income tax benefit in both 2020 and 2019. Our effective tax rates for the years ended December 31, 
2020 and 2019 were different from the statutory federal income tax rate of 21% primarily due to the benefit recognized from 
the tax credits transferred to us from our tax credit partnership investments. In addition, our effective tax rate in 2020 was also 
impacted by the non-deductible portion of the goodwill impairment related to the Specialty P&C reporting unit recognized 
during the third quarter of 2020. See further discussion of the goodwill impairment under the heading "Goodwill / Intangibles" 
in the Critical Accounting Estimates section and Notes 1 and 6 of the Notes to Consolidated Financial Statements and further 
information on other notable items impacting our effective tax rate in the Segment Results - Corporate section that follows 
under the heading "Taxes."

Operating Ratio

Our operating ratio is our combined ratio, less our investment income ratio. This ratio provides the combined effect of 

underwriting profitability and investment income. Our operating ratio for the years ended December 31, 2020 and 2019 was as

 (3.5 pts) 

Our operating ratio for the year ended December 31, 2020 as compared to 2019 decreased approximately 3.5 percentage 
points driven by a lower net loss ratio in our Specialty P&C segment. The decrease in our net loss ratio in our Specialty P&C 
segment was driven by the change in prior year reserve development and, to a lesser extent, an improvement in our current 
accident year net loss ratio primarily the result of our re-underwriting efforts and focus on rate adequacy. See previous 
discussion in this section under the heading "Expenses" and further discussion in our Segment Operating Results - Specialty 
Property & Casualty section that follows under the heading "Losses and Loss Adjustment Expenses." The decrease in our 
operating ratio in 2020 as compared to 2019 was partially offset by a lower investment income ratio primarily due to a decrease 
in our allocation to equities and lower yields on our short-term investments and corporate debt securities given the recent 
actions taken by the Federal Reserve in response to COVID-19.

ROE

ROE is calculated as net income (loss) divided by the average of beginning and ending shareholders’ equity. This ratio 

measures our overall after-tax profitability and shows how efficiently capital is being used. ROE for the years ended 
December 31, 2020 and 2019 was as follows:

Our ROE for the year ended December 31, 2020 primarily reflected a $161.1 million pre-tax goodwill impairment 

recognized related to the Specialty P&C reporting unit during the third quarter of 2020, which decreased our ROE by 
approximately 11.2 percentage points. See further discussion of the goodwill impairment under the heading "Goodwill / 
Intangibles" in the Critical Accounting Estimates section and Notes 1 and 6 of the Notes to Consolidated Financial Statements. 
Additionally, the decrease in our ROE in 2020 as compared to 2019 reflected lower consolidated net realized investment gains 

76

and, to a lesser extent, a decrease in our consolidated net investment income (see previous discussion in this section under the 
heading "Revenues").

Book Value per Share

Book value per share is calculated as total shareholders' equity at the balance sheet date divided by the total number of 

common shares outstanding. This ratio measures the net worth of the Company to shareholders on a per share basis. Our book 
value per share at December 31, 2020 as compared to December 31, 2019 is shown in the following table.

Non-GAAP Financial Measures

Non-GAAP operating income (loss) is a financial measure that is widely used to evaluate performance within the 

insurance sector. In calculating Non-GAAP operating income (loss), we have excluded the effects of the items listed in the 
following table that do not reflect normal results. We believe Non-GAAP operating income (loss) presents a useful view of the 
performance of our insurance operations, however it should be considered in conjunction with net income (loss) computed in 
accordance with GAAP. 

The following table is a reconciliation of net income (loss) to Non-GAAP operating income (loss):

(1) Net realized investment gains (losses) on investments related to SPCs are recognized in our Segregated Portfolio Cell

Reinsurance segment. SPC results, including any realized gain or loss, that are attributable to external cell participants are
reflected in the SPC dividend expense (income). To be consistent with our exclusion of net realized investment gains (losses)
recognized in earnings, we are excluding the portion of net realized investment gains (losses) that is included in the SPC
dividend expense (income) which is attributable to the external cell participants.

(2) The 21% rate is the statutory tax rate associated with the taxable or tax deductible items listed above. The taxes associated

with the net realized investment gains (losses) related to SPCs in our Segregated Portfolio Cell Reinsurance segment are paid
by the individual SPCs and are not included in our consolidated tax provision or net income (loss); therefore, both the net
realized investment gains (losses) from our Segregated Portfolio Cell Reinsurance segment and the adjustment to exclude the
portion of net realized investment gains (losses) included in the SPC dividend expense (income) in the table above are not tax
effected. The portion of the 2020 goodwill impairment loss that is tax deductible was tax affected at the statutory tax rate
(21%). The remaining portion of the 2020 goodwill impairment loss is not tax deductible and therefore had no associated
income tax benefit.

Changes in our premium volume within our Specialty P&C segment are driven by four primary factors: (1) the amount of 

new business written, (2) our retention of existing business, (3) the premium charged for business that is renewed, which is 
affected by rates charged and by the amount and type of coverage an insured chooses to purchase and (4) the timing of premium 
written through multi-period policies. In addition, premium volume may periodically be affected by shifts in the timing of 
renewals between periods. The professional liability market, which accounts for a majority of the revenues in this segment, 
remains challenging as physicians continue joining hospitals or larger group practices and are thus no longer purchasing 
individual or group policies in the standard market. In addition, some competitors have chosen to compete primarily on price; 
both factors may impact our ability to write new business and retain existing business. Furthermore, the insurance and 
reinsurance markets have historically been cyclical, characterized by extended periods of intense price competition and other 
periods of reduced competition. The professional liability area has been particularly affected by these cycles. Underwriting 
cycles are generally driven by an excess of capacity available and actively pursuing business that is deemed profitable. Changes 
in the frequency and severity of losses may affect the cycles of the insurance and reinsurance markets significantly. During 
“soft markets” where price competition is high and underwriting profits are poor, growth and retention of business become 
challenging which may result in reduced premium volumes. 

As a result of COVID-19, we continue to experience downward pressure on our premium volume resulting from new 
business disruptions. We have also experienced reductions in exposure due to insureds moving to part-time as a result of a 
general reduction in non-COVID-19 healthcare consumption and suspension of elective medical procedures. However, the 
length and magnitude of such changes depends on future developments, which are highly uncertain and cannot be predicted. In 
an effort to provide premium relief for insureds adversely impacted by the COVID-19 pandemic and to adjust for changes in 
exposures we granted premium credits totaling $4.1 million during the year ended December 31, 2020.

(1) Standard Physician premium was our greatest source of premium revenues in both 2020 and 2019 and is predominately
comprised of twelve month term policies. The decrease in twelve month term policies in 2020 was driven by retention
losses  and,  to  a  lesser  extent,  premium  credits  granted  as  a  result  of  the  COVID-19  pandemic,  partially  offset  by  an
increase in renewal pricing, conversion of twenty-four month term policies and, to a lesser extent, new business written.
In  addition,  twelve  month  term  policies  in  2020  included  adjustments  related  to  loss  sensitive  policies  which  increased
written and earned premium. Renewal pricing increases in 2020 reflect the rising loss cost environment and new business
written  reflects  the  impact  of  lower  submissions  as  a  result  of  the  COVID-19  pandemic  as  well  as  general  market
conditions. The lower retention for 2020 is largely attributable to our focus on underwriting discipline as we continue to
emphasize careful risk selection, rate adequacy, improved contract terms and a willingness to walk away from business
that does not fit our goal of achieving a long-term underwriting profit. In addition, we have implemented a targeted state
strategy to reassess our underwriting appetite in certain unprofitable states which impacted our retention rate in the current
period.  We  will  continue  to  perform  a  detailed  evaluation  of  venues,  specialties  and  other  areas  to  improve  our
underwriting results. These strategies resulted in our non-renewal of several large policies totaling $8.7 million in 2020.
We anticipate a lower than average level of retention to persist as we continue to reevaluate certain states and books of
business and set our rates to reflect our observations of higher severity trends. Standard Physician premium also includes
twenty-four  month  term  premiums  that  were  offered  to  physician  insureds  in  one  selected  jurisdiction.  The  decrease  in
twenty-four month term premiums in 2020 primarily reflected the normal cycle of renewals (policies subject to renewal in
2020 were previously written in 2018, rather than in 2019). In addition, the decrease in twenty-four month term premiums
also reflected our re-underwriting of the majority of renewed policies to twelve month term policies, as we ceased offering
twenty-four month term policies beginning in the second quarter of 2020.

(2) Custom  Physician  premium  includes  large  complex  physician  groups,  multi-state  physician  groups  and  non-standard
physicians and is written primarily on an excess and surplus lines basis. The decrease in premium in 2020 was driven by
retention  losses  due  to  our  focus  on  underwriting  discipline  as  we  continue  to  emphasize  careful  risk  selection,  rate
adequacy, improved contract terms and a willingness to walk away from business that does not fit our goal of achieving a

80

long-term underwriting profit. Included in these retention losses is a large national healthcare account that did not renew 
on terms offered by us during the second quarter of 2020 which resulted in a $9.0 million decrease in Custom Physician 
premium  and,  as  a  result,  a  decrease  to  our  Specialty  retention  rate  of  4  percentage  points;  this  account  exercised  its 
contractual option to purchase extended reporting endorsement or "tail" coverage (see further discussion in footnote 7 that 
follows).  We  anticipate  retention  rates  to  begin  to  normalize  going  forward  as  we  substantially  completed  our  re-
underwriting efforts as of the end of  2020, except for a few large accounts that were renewed on a two-year term in 2019 
that will be carefully evaluated in 2021. The decrease in Custom Physician premium in 2020 as compared to 2019 also 
reflects  net  timing  differences  of  $1.9  million  related  to  the  prior  year  renewal  of  two  policies,  partially  offset  by  an 
increase  in  renewal  pricing  and,  to  a  lesser  extent,  new  business  written.  Renewal  pricing  increases  in  2020  reflect  the 
rising  loss  cost  environment  and  new  business  written  reflects  the  impact  of  lower  submissions  as  a  result  of  the 
COVID-19 pandemic as well as general market conditions.

(3) Hospitals  and  Facilities  premium  (which  includes  hospitals,  surgery  centers  and  miscellaneous  medical  facilities)
increased  in  2020  as  compared  to  2019  primarily  due  to  an  increase  in  renewal  pricing  and,  to  a  lesser  extent,  new
business written, including the addition of two policies totaling $3.2 million, partially offset by retention losses. Renewal
pricing increases in 2020 reflect rate increases and contract modifications that we believe are appropriate given the current
loss environment and new business written reflects lower submissions as a result of COVID-19 as well as general market
conditions. Retention losses in 2020 were driven by our decision not to renew certain products and the loss of two large
policies totaling $4.3 million. As we have substantially completed our re-underwriting efforts on certain books of business
as of the end of the third quarter of 2020, we anticipate retention rates to begin to normalize going forward.

(4) Senior Care premium includes facilities specializing in long term residential care primarily for the elderly ranging from
independent living through skilled nursing. Our Senior Care premium decreased in 2020 as compared to 2019 primarily
due to retention losses, partially offset by new business written. Retention losses in 2020 were driven by our decision not
to renew certain classes of Senior Care business based on our expectations of poor loss performance, including our non-
renewal of two large policies totaling $7.2 million. As of the end of the third quarter of 2020, we have completed our re-
underwriting efforts on certain books of business and anticipate retention rates to begin to normalize going forward.

(5) We offer custom alternative risk solutions including loss portfolio transfers for healthcare entities who, most commonly,
are exiting a line of business, changing an insurance approach or simply preferring to transfer risk. In the third quarter of
2019, we entered into a loss portfolio transfer with a regional hospital group which resulted in $0.9 million of retroactive
premium written and fully earned in 2019 (see further discussion in footnote 7 that follows).

(6) Our Small Business Unit is primarily comprised of premium associated with podiatrists, legal professionals, dentists and
chiropractors. Our Small Business Unit premium decreased in 2020 as compared to 2019 driven by retention losses and,
to a lesser extent, reductions in exposure of $2.0 million primarily due to our insureds moving to part-time as a result of a
general  reduction  in  non-COVID-19  healthcare  consumption,  partially  offset  by  new  business  written  and,  to  a  lesser
extent, an increase in renewal pricing. The increase in renewal pricing in 2020 was primarily the result of an increase in
the rate charged for certain renewed policies in select states.

(7) We offer extended reporting endorsement or "tail" coverage to insureds who discontinue their claims-made coverage with
us, and we also periodically offer tail coverage through stand-alone policies. Tail coverage premiums are generally 100%
earned  in  the  period  written  because  the  policies  insure  only  incidents  that  occurred  in  prior  periods  and  are  not
cancellable. The amount of tail coverage premium written can vary significantly from period to period. The increase in
2020 as compared to 2019 was due to a large national healthcare account that exercised its contractual option to purchase
tail coverage which resulted in $14.3 million of one-time premium written and fully earned in the second quarter of 2020,
somewhat  offset  by  the  tail  coverage  provided  in  connection  with  the  aforementioned  third  quarter  2019  loss  portfolio
transfer.

(8) Our Medical Technology Liability business is marketed throughout the U.S.; coverage is typically offered on a primary
basis, within specified limits, to manufacturers and distributors of medical technology and life sciences products including
entities conducting human clinical trials. In addition to the previously listed factors that affect our premium volume, our
Medical Technology Liability premium is impacted by the sales volume of insureds. Our Medical Technology Liability
premium remained relatively unchanged in 2020 as compared to 2019 as retention losses and renewal pricing decreases
were  offset  by  new  business  written.  New  business  written  in  2020  reflects  the  addition  of  a  few  COVID-19  related
policies. Retention losses in 2020 are primarily attributable to an increase in competition on terms and pricing. Renewal
pricing  decreases  in  2020  are  primarily  due  to  changes  in  the  sales  volume  of  certain  insureds,  including  changes  in
COVID-19 related exposure on several renewing policies.

(9) This  component  of  gross  premiums  written  includes  all  other  product  lines  within  our  Specialty  P&C  segment.  The

decrease in 2020 was due to the effect of our non-renewal of a $1.5 million specialty contractual liability policy.

81

(10) Certain components of our gross premiums written include alternative market premiums. We currently cede either all or a
portion  of  the  alternative  market  premium,  net  of  reinsurance,  to  three  SPCs  of  our  wholly  owned  Cayman  Islands
reinsurance  subsidiaries,  Inova  Re  and  Eastern  Re,  which  are  reported  in  our  Segregated  Portfolio  Cell  Reinsurance
segment (see further discussion in the Ceded Premiums Written section that follows). The portion not ceded to the SPCs is
retained within our Specialty P&C segment.

The decrease in alternative market gross premiums written in 2020 as compared to 2019 was due to retention losses driven 
by the loss of a $1.4 million Senior Care policy that chose to utilize self-insurance, slightly offset by policy endorsements.

We  are  committed  to  a  rate  structure  that  will  allow  us  to  fulfill  our  obligations  to  our  insureds,  while  generating 
competitive long-term returns for our shareholders. Our pricing continues to be based on expected losses as indicated by our 
historical loss data and available industry loss data. In recent years, this practice has resulted in gradual rate increases and we 
anticipate further rate increases due to indications of increasing loss severity. Additionally, the pricing of our business includes 
the  effects  of  filed  rates,  surcharges  and  discounts.  Renewal  pricing  also  reflects  changes  in  our  exposure  base,  deductibles, 
self-insurance retention limits and other policy terms and conditions.

For our Specialty P&C segment, we calculate retention as annualized renewed premium divided by all annualized 

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

Ceded Premiums Written

Ceded premiums represent the amounts owed to our reinsurers for their assumption of a portion of our losses. For our 

HCPL and Medical Technology Liability excess of loss reinsurance arrangements in effect prior to October 1, 2020, we 
generally retained the first $1 million in risk insured by us and ceded coverages in excess of this amount. Effective October 1, 
2020, we generally retain the first $2 million in risk insured by us and cede coverages in excess of this amount. For our HCPL 
coverages, we will also retain from 0% to 14.5% of the next $24 million of risk for coverages in excess of $2 million. For our 
Medical Technology Liability treaty which also renewed effective October 1, 2020, we also retain 2.5% of the next $8 million 
of risk for coverages in excess of $2 million. These changes in terms for both our HCPL and Medical Technology Liability 
treaties resulted in a reduction to the gross rate paid for the treaty year effective October 1, 2020. We pay our reinsurers a 
ceding premium in exchange for their accepting the risk, and in certain of our excess of loss arrangements, the ultimate amount 
of which is determined by the loss experience of the business ceded, subject to certain minimum and maximum amounts.

(1) We generally reinsure risks under our excess of loss reinsurance arrangements pursuant to which the reinsurers agree
to assume all or a portion of all risks that we insure above our individual risk retention levels, up to the maximum
individual limits offered. Premium due to reinsurers also fluctuates with the volume of written premium subject to
cession  under  the  arrangement.  In  certain  of  our  excess  of  loss  reinsurance  arrangements,  the  premium  due  to  the
reinsurer is determined by the loss experience of that business reinsured, subject to certain minimum and maximum
amounts.  The  decrease  in  ceded  premiums  written  under  our  excess  of  loss  reinsurance  arrangements  in  2020  as
compared to 2019 primarily reflected a decrease in the overall volume of gross premiums written subject to cession
and, to a lesser extent, certain of our reinsurance arrangements reaching maximum limits eligible for cession on treaty
years effective October 1, 2017 and 2018. The decrease in ceded premiums written in 2020 also reflected the reduced
rate  on  the  treaty  year  effective  October  1,  2020,  partially  offset  by  the  effect  of  changes  to  both  minimum  and
maximum limits for the treaty year effective October 1, 2019.

(2) We  have  entered  into  various  shared  risk  arrangements,  including  quota  share,  fronting  and  captive  arrangements,
with certain large healthcare systems and other insurance entities. These arrangements include our Ascension Health
and CAPAssurance programs. While we cede a large portion of the premium written under these arrangements, they
provide  us  an  opportunity  to  grow  net  premium  through  strategic  partnerships.  Effective  October  1,  2020,  our
arrangement with CAPAssurance was mutually dissolved as a result of our pending acquisition with NORCAL and
their  concentration  in  the  state  of  California.  The  decrease  in  ceded  premiums  written  under  our  shared  risk
arrangements  in  2020  as  compared  to  2019  was  primarily  due  to  a  decrease  in  premium  ceded  to  our  Ascension
Health program, our non-renewal of two large policies in certain of our other shared risk arrangements and, to a lesser
extent, the aforementioned dissolution of our arrangement with CAPAssurance.

(3) As previously discussed, as a part of our alternative market solutions, all or a portion of certain healthcare premium
written is ceded to SPCs in our Segregated Portfolio Cell Reinsurance segment under either excess of loss or quota
share  reinsurance  agreements,  depending  on  the  structure  of  the  individual  program.  See  the  Segment  Results  -
Segregated Portfolio Cell Reinsurance section for further discussion on the cession to the SPCs from our Specialty
P&C segment. The decrease in premiums ceded to SPCs during 2020 as compared to 2019 was primarily due to the
loss of one large Senior Care policy (see discussion in footnote 10 under the heading "Gross Premiums Written").

84

(4) Given the length of time that it takes to resolve our claims, many years may elapse before all losses recoverable under
a reinsurance arrangement are known. As a part of the process of estimating our loss reserve we also make estimates
regarding  the  amounts  recoverable  under  our  reinsurance  arrangements.  As  previously  discussed,  the  premiums
ultimately ceded under certain of our excess of loss reinsurance arrangements are subject to the losses ceded under
the arrangements. As part of the review of our reserves during 2020 and 2019, we increased our estimate of expected
losses  and  associated  recoveries  for  prior  year  ceded  losses,  as  well  as  our  estimate  of  ceded  premiums  owed  to
reinsurers;  however,  this  increase  was  lower  in  2020  as  compared  to  2019  due  to  reaching  the  maximum  level  of
premium due under certain prior year excess of loss arrangements. Changes to estimates of premiums ceded related to
prior accident years are fully earned in the period the changes in estimates occur.

Ceded Premiums Ratio

As shown in the table below, our ceded premiums ratio was affected in both 2020 and 2019 by revisions to our estimate of 

premiums owed to reinsurers related to coverages provided in prior accident years.

Net Premiums Earned

Net premiums earned consist of gross premiums earned less the portion of earned premiums that we cede to our reinsurers 

for their assumption of a portion of our losses. Because premiums are generally earned pro rata over the entire policy period, 
fluctuations in premiums earned tend to lag those of premiums written. Generally, our policies carry a term of one year; 
however, prior to the third quarter of 2020, we wrote certain Standard Physician policies with a twenty-four month term, and a 
few of our Medical Technology Liability policies have a multi-year term. Tail coverage premiums are generally 100% earned in 
the period written because the policies insure only incidents that occurred in prior periods and are not cancellable. Retroactive 
coverage premiums are 100% earned at the inception of the contract, as all of the associated underlying loss events occurred in 
the past. Additionally, any ceded premium changes due to changes to estimates of premiums owed under reinsurance 
agreements for prior accident years are fully earned in the period of change.

Net premiums earned were as follows:

 (5.0%)

 (4.3%) 

The decrease in gross premiums earned in 2020 as compared to 2019 was driven by the pro rata effect of a decrease in the 
volume of written premium during the preceding twelve months, predominantly in our Specialty line of business, due to our re-
underwriting efforts. The decrease in gross premiums earned also reflects the effect of a prior year loss portfolio transfer which 
resulted in $2.7 million of one-time premium written and fully earned in 2019 (see previous discussion in footnotes 5 and 7 
under the heading "Gross Premiums Written"). The decrease in gross premiums earned in 2020 was somewhat offset by 
premium adjustments related to loss sensitive policies which increased earned premium by $2.9 million and decreased earned 
premium by $1.6 million in 2019. In addition, the decrease in gross premiums earned was largely offset by $14.3 million of 
one-time premium written and fully earned in the second quarter of 2020 associated with the tail coverage purchased by a large 
national healthcare account (see previous discussion in footnote 7 under the heading "Gross Premiums Written").

The decrease in ceded premiums earned during 2020 as compared to 2019 reflected the effect of adjustments made during 
2020 and 2019 to ceded premiums owed under reinsurance agreements related to prior accident year losses. After removing the 
effect of prior accident year ceded premium adjustments from both years, ceded premiums earned decreased $5.2 million in 
2020 as compared to 2019. The remaining decrease was driven by the pro rata effect of a decrease in premium ceded under our 
shared risk and excess of loss arrangements during the preceding twelve months.

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 ECO/XPL losses.

Accident year refers to the accounting period in which the insured event becomes a liability of the insurer. For claims-
made policies, which represent the majority of the premiums written in our Specialty P&C segment, the insured event generally 
becomes a liability when the event is first reported to us. For occurrence policies, the insured event becomes a liability when the 
event takes place. For retroactive coverages, the insured event becomes a liability at inception of the underlying contract. We 
believe that measuring losses on an accident year basis is the best measure of the underlying profitability of the premiums 
earned in that period, since it associates policy premiums earned with the estimate of the losses incurred related to those policy 
premiums.

The following table summarizes calendar year net loss ratios by separating losses between the current accident year and 

all prior accident years. Additionally, the table shows our current accident year net loss ratios were affected by revisions to our 
estimate of premiums owed to reinsurers related to coverages provided in prior accident years. The net loss ratios for our 
Specialty P&C segment were as follows:

Our current accident year net loss ratio in 2020 and 2019 was impacted by a large national healthcare account. In 
2019,  we  increased  our  reserve  estimates  for  this  account's  claims-made  policy  during  the  fourth  quarter  of  2019 
based on our in-depth review of our current accident year reserve which we believed best reflected emerging data at 
that time. In addition, we recognized a PDR of $9.2 million during the fourth quarter of 2019 related to this account 
which increased current accident year net losses. The PDR represented an estimated premium deficiency associated 
with the unearned premium of this account's claims-made policy as of the end of 2019. During 2020, this PDR was 
amortized back into current accident year net losses which offset the impact of the losses incurred in 2020 associated 
with the earned premium related to this account's claims-made policy. During the second quarter of 2020, the policy 

87

term associated with this account's claims-made policy expired. This account did not renew on terms offered by us 
and the insured exercised its contractual option to purchase the extended reporting endorsement or "tail" coverage 
resulting in a net underwriting loss of $45.7 million in 2020. The net impact of this large national healthcare account 
resulted in a 2.9 percentage point increase in our current accident year net loss ratio in 2020 as compared to 2019. 
Also during the second quarter of 2020, we established a $10 million reserve for COVID-19; no adjustment has been 
made  to  this  reserve  since  the  second  quarter  of  2020.  This  reserve  represents  our  best  estimate  of  ultimate 
COVID-19 related losses based on currently available information and reported incidents, and accounted for a 2.2 
percentage  point  increase  in  our  current  accident  year  net  loss  ratio  in  2020.  As  a  result  of  our  actuarial  analysis 
performed at the end of 2019, we increased our reserves related to DDR coverage endorsements which accounted for 
approximately 1.5 percentage points of the decrease in the current accident year net loss ratio in 2020 as compared 
to  2019;  no  adjustment  was  made  to  these  reserves  in  2020.  After  removing  the  impact  of  the  large  national 
healthcare  account  in  both  2020  and  2019,  the  2020  COVID-19  reserve  and  actuarial  adjustment  to  our  DDR 
reserves in 2019, our current accident year net loss ratio in 2020 improved 4.5 percentage points primarily reflecting 
the impact of decreases in certain loss ratios during 2020 and, to a lesser extent, the effect of changes in premium 
adjustments related to loss sensitive policies (see previous discussion under the heading "Net Premiums Earned"). 
The  decreases  in  loss  ratios  during  2020  were  primarily  in  our  Standard  Physician,  Specialty  and  Small  Business 
Unit lines of business as a result of our re-underwriting efforts and focus on rate adequacy.

We re-evaluate our previously established reserve each quarter based upon the most recently completed actuarial analysis 

supplemented by any new analysis, information or trends that have emerged since the date of that study. We also take into 
account currently available industry trend information. We continue to see elevated loss severity in the broader medical 
professional liability industry and are observing indications of these increased severity trends in our paid loss data.  While we 
have established a reserve for COVID-19 related losses, we have also observed a significant reduction in claims frequency as 
compared to 2019, some of which is likely associated with the COVID-19 pandemic and the disruption of the court systems; 
however, we have remained cautious in recognizing these favorable frequency trends in our current accident year reserve due to 
the possibility of delays in reporting and uncertainty surrounding the length and severity of the pandemic.

We recognized net favorable prior year reserve development of $27.5 million for the year ended December 31, 2020 as 

compared to net unfavorable prior year reserve development of $5.7 million for the year ended December 31, 2019. Favorable 
development recognized during 2020 principally related to accident years 2014 through 2017. Net unfavorable prior year 
reserve development in 2019 included $51.5 million of unfavorable reserve development related to our reserves for the 
previously mentioned large national healthcare account that has experienced losses far exceeding the assumptions we made 
when underwriting the account, beginning in 2016; unfavorable development recognized during 2019 related to accident years 
2016 through 2018. Excluding the unfavorable development related to this account, the Specialty P&C segment recognized 
favorable prior year reserve development totaling $45.8 million in 2019. Prior accident year development recognized for years 
ended December 31, 2020 and 2019 included a reduction in our reserve for potential ECO/XPL claims of $4.0 million and $0.3 
million, respectively. Development recognized in both 2020 and 2019 also included favorable prior year reserve development 
attributable to our medical technology liability line of business of $8.6 million and $13.3 million, respectively.

A detailed discussion of factors influencing our recognition of loss development is included in our Critical Accounting 
Estimates section under the heading "Reserve for Losses and Loss Adjustment Expenses." Assumptions used in establishing our 
reserve are regularly reviewed and updated by management as new data becomes available. Any adjustments necessary are 
reflected in the then current operations. Due to the size of our reserve, even a small percentage adjustment to the assumptions 
can have a material effect on our results of operations for the period in which the change is made, as was the case in both 2020 
and 2019.

Underwriting, Policy Acquisition and Operating Expenses

Our Specialty P&C segment underwriting, policy acquisition and operating expenses for the years ended December 31, 

2020 and 2019 were comprised as follows:

 (9.0%)
 (12.4%) 
 (8.9%) 

DPAC amortization decreased during the year ended December 31, 2020 as compared to 2019 driven by a decrease in 

earned premium, excluding the effect of the premium earned from the tail coverage associated with a large national healthcare 
account from the second quarter of 2020 as there were no deferred acquisition costs associated with the tail premium (see 
discussion under the heading "Gross Premiums Written"). In addition, the decrease in DPAC amortization reflected a decrease 
in brokerage expenses due to our non-renewal of certain products written on an excess and surplus lines basis in our Specialty 
line of business (see discussion under the heading "Gross Premiums Written") as well as a decrease in agent commissions and 
premium taxes due to a lower volume of premium written. Partially offsetting the decrease in DPAC amortization in 2020 was 
an increase in medical costs associated with employee health plans, one-time employee severance charges of $0.6 million and, 
to a lesser extent, a decrease in ceding commission income, which is an offset to expense, from certain of our shared risk 
arrangements.

Management fees are charged pursuant to a management agreement by the Corporate segment to the operating 

subsidiaries within our Specialty P&C segment for services provided based on the extent to which services are provided to the 
subsidiary and the amount of premium written by the subsidiary. While the terms of the management agreement were consistent 
between 2020 and 2019, fluctuations in the amount of premium written by each subsidiary can result in corresponding 
variations in the management fee charged to each subsidiary during a particular period.

Other underwriting and operating expenses decreased during the year ended December 31, 2020 as compared to 2019 
primarily driven by a decrease in various operational expenses resulting from incremental improvements over the past year 
including organizational structure enhancements and improved operating efficiencies. The decrease in operating expenses also 
reflected a reduction in travel-related costs of $3.3 million in 2020 as a result of the COVID-19 pandemic and, to a lesser 
extent, a reduction in employer contributions to the ProAssurance Savings Plan (see further discussion in Note 17 of the Notes 
to Consolidated Financial Statements). Furthermore, the decrease in operating expenses in 2020 as compared to 2019 also 
included a reduction in fees associated with a data analytics services agreement of $0.6 million driven by an amendment to the 
agreement executed during the fourth quarter of 2020 (see further discussion in Note 9 of the Notes to Consolidated Financial 
Statements). The decrease in 2020 was largely offset by one-time expenses of $3.4 million mainly comprised of early 
retirement benefits granted to certain employees in 2020 as well as expenses associated with the restructuring of our HCPL field 
office organization, consisting of employee severance charges and lease exit costs due to a reduction in physical office 
locations. The decrease in operating expenses in 2020 was also somewhat offset by an increase of $0.4 million in accrued paid 
time off due to lower employee utilization of vacation time likely associated with the COVID-19 pandemic.

Underwriting Expense Ratio (the Expense Ratio)

Our expense ratio for the Specialty P&C segment for the year ended December 31, 2020 as compared to 2019 was as

The remaining decrease in our expense ratio during 2020 as compared to 2019 of 1.7 percentage points primarily reflected 
the impact of a decrease in various operational expenses resulting from incremental improvements over the past year including 
organizational structure enhancements and improved operating efficiencies and, to a lesser extent, the reduction in employer 
contributions to the ProAssurance Savings Plan.

Segment Results - Workers' Compensation Insurance

Our Workers' Compensation Insurance segment includes workers' compensation products provided to employers 

generally with 1,000 or fewer employees, as discussed in Note 16 of the Notes to Consolidated Financial Statements. Workers' 
compensation products offered include guaranteed cost policies, policyholder dividend policies, retrospectively-rated policies, 
deductible policies and alternative market programs. Alternative market programs include program design, fronting, claims 
administration, risk management, SPC rental, asset management and SPC management services. Alternative market program 
premiums are 100% ceded to either the SPCs within our Segregated Portfolio Cell Reinsurance segment or, to a limited extent, 
an unaffiliated captive insurer for one program. Our Workers' Compensation Insurance segment results reflected pre-tax 
underwriting profit or loss from these workers' compensation products, exclusive of investment results, which are included in 
our Corporate segment. Segment results included the following:

*The change in retrospectively-related policies included adjustments that decreased premium by $2.5 million and $2.1 million during
the years ended December 31, 2020 and 2019, respectively.

Gross premiums written in our traditional business decreased during the year ended December 31, 2020 as compared to
2019, which primarily reflected renewal rate decreases, retention losses and a reduction in audit premium and new business 
written. The reduction in audit premium included a reduction in our EBUB estimate of $1.3 million in 2020. Renewal rate 
decreases were 4% in 2020, which were unchanged as compared to 2019. Renewal retention for our traditional business was 
84% during 2020 as compared to 79% during 2019. New business written totaled $23.7 million in 2020 as compared to 
$27.0 million in 2019. 

Gross premiums written in our alternative market business decreased during the year ended December 31, 2020 as 
compared to 2019, which primarily reflected renewal rate decreases, retention losses and a decrease in audit premium. In 
addition, the decline in alternative market business in 2020 also reflected the reduction in premium funding for one of our large 
alternative market programs (see further discussion in our Segment Results - Segregated Portfolio Cell Reinsurance section that 
follows). Renewal rate decreases were 4% in 2020 as compared to 5% in 2019. Retention in our alternative market business was 
84% in 2020 which reflected the impact of the aforementioned reduction in premium funding for a large alternative market 
program. A decrease in renewal rate and retention losses were partially offset by new business of $3.7 million in 2020. We 
retained 100% of the 23 workers' compensation alternative market programs up for renewal during the year ended 
December 31, 2020. During the second quarter of 2020, we added one new workers' compensation alternative market program 
at Inova Re with $1.1 million in premiums written during the year ended December 31, 2020.

Our traditional and alternative market premiums written were impacted by reductions in payroll exposure and policy 
cancellations related to the economic impact of COVID-19. Reductions in payroll exposure and policy cancellations related to 
the economic impact of COVID-19 reduced premiums written by approximately $3.6 million for the year ended December 31, 
2020. We expect continued downward pressure in future quarters on our workers' compensation premium resulting from further 
reductions in insured payroll exposure; however, the length and magnitude of such changes depends on future developments, 
which are highly uncertain and cannot be predicted.

Our Workers' Compensation Insurance segment cedes alternative market business under a 100% quota share reinsurance 
agreement, net of a ceding commission, to SPCs in our Segregated Portfolio Cell Reinsurance segment and, to a limited extent, 
to an unaffiliated captive insurer. The decrease in premiums ceded to SPCs during the year ended December 31, 2020 reflects 
the reduction in alternative market gross premiums written as discussed above under the heading "Gross Premiums Written".

Under our external reinsurance agreement for traditional business, we retain the first $0.5 million in risk insured by us and 
cede losses in excess of this amount on each loss occurrence under our primary external reinsurance treaty, subject to an AAD. 
The AAD for the contract year effective May 1, 2019 was $3.9 million of incurred losses in excess of the $0.5 million per 
occurrence retention, or approximately 2.1% of subject earned premium. Effective May 1, 2020, our primary reinsurance layer 
was renewed at a slightly higher rate than the expiring year, with an increase in the AAD to 3.16% of subject earned premium 
for incurred losses in excess of the per occurrence retention. Per our reinsurance agreements, we cede premiums related to our 
traditional business on an earned premium basis. The decrease in premiums ceded to external reinsurers during the year ended 
December 31, 2020 primarily reflected the decrease in traditional earned premium.

Changes in the return premium estimate reflected the loss experience under the reinsurance contract for the years ended 
December 31, 2020 and 2019. The change in estimated return premium for the year ended December 31, 2020 reflected prior 
year loss development on previously reported reinsured claims.

The above table reflects ceded premiums earned as a percent of gross premiums earned. As discussed above, we cede 
premiums related to our traditional business to external reinsurers on an earned premium basis. The ceded premiums ratio in 
2020 primarily reflects the reinsurance rates in effect for the contract period beginning May 1, 2020.

Net Premiums Earned

Net premiums earned consist of gross premiums earned less the portion of earned premiums that we cede to SPCs in our 
Segregated Portfolio Cell Reinsurance segment, external reinsurers and the unaffiliated captive insurer. Because premiums are 
generally earned pro rata over the entire policy period, fluctuations in premiums earned tend to lag those of premiums written. 
Our workers’ compensation policies are twelve month term policies, and premiums are earned on a pro rata basis over the 
policy period. Net premiums earned also include premium adjustments related to the audit of our insureds' payrolls, changes in 
our EBUB estimate and premium adjustments related to retrospectively-rated policies. Payroll audits are conducted subsequent 
to the end of the policy period and any related adjustments are recorded as fully earned in the current period. In addition, we 
record an estimate for EBUB and evaluate the estimate on a quarterly basis.

The decrease in net premiums earned during the year ended December 31, 2020 as compared to 2019 primarily reflected 

the pro rata effect of a reduction in net premiums written during the preceding twelve months and, to a lesser extent, the 
reduction in our EBUB estimate and the impact of retrospectively-rated policy adjustments. We reduced our EBUB estimate by 
$1.3 million during 2020 which primarily reflected a reduction in earned payroll exposure. As a result of the economic impact 
of COVID-19, we expect future reductions in payroll exposure related to in-force policies that could result in a significant 
decrease in audit premium and our EBUB estimate. We will continue to monitor and adjust the estimate, if necessary, based on 
changes in insured payrolls and economic conditions, as experience develops or new information becomes known; however, the 
length and magnitude of such changes depends on future developments, which are highly uncertain and cannot be predicted. 
There was no adjustment to our EBUB estimate during the year ended December 31, 2019. Premium adjustments related to 
retrospectively-rated policies decreased premiums by 2.5 million and $2.1 million during the years ended December 31, 2020 
and 2019, respectively.

Losses and Loss Adjustment Expenses

We estimate our current accident year loss and loss adjustment expenses based on an expected loss ratio. Incurred losses 
and loss adjustment expenses for the current accident year are determined by applying the expected loss ratio to net premiums 
earned for the respective period. The following table summarizes calendar year net loss ratios by separating losses between the 
current accident year and all prior accident years. Calendar year and current accident year net loss ratios by component were as 
follows:

The increase in the current accident year loss ratio for the year ended December 31, 2020 primarily reflected the 
continuation of intense price competition and the resulting renewal rate decreases, partially offset by favorable claim trends, 
including lower claims frequency and severity. As a result of the COVID-19 pandemic, legislative and regulatory bodies in 
certain states have changed or are considering changes to compensability requirements and presumptions for certain types of 
workers related to COVID-19 claims. These endeavors could have an adverse impact on the frequency and severity related to 
COVID-19 claims. Furthermore, the current economic conditions resulting from the COVID-19 pandemic have introduced 
significant risk of a prolonged recession, which could have an adverse impact on our return to wellness efforts and the ability of 
injured workers to return to work, resulting in a potential reduction in favorable claim trends in future periods.

Calendar year incurred losses (excluding IBNR) ceded to our external reinsurers decreased $11.3 million for the year 
ended December 31, 2020 as compared to 2019. Current accident year ceded incurred losses (excluding IBNR) decreased $8.2 
million as compared to 2019. The decrease in ceded incurred losses reflects lower severity-related claim activity during 2020 
and, on a calendar year basis, favorable development on prior year reinsured claims.

We recognized net favorable prior year development related to our previously established reserve of $7.0 million for the 
year ended December 31, 2020 as compared to $7.8 million for 2019. The net favorable prior year reserve development for the 
years ended December 31, 2020 and 2019 reflected overall favorable trends in claim closing patterns. Net favorable 
development for the year ended December 31, 2020 primarily related to the 2014 through 2017 accident years. Net favorable 
development for the year ended December 31, 2019 primarily related to the 2015 and 2016 accident years and included a fair 
value adjustment of $1.6 million related to the amortization of purchase accounting. The fair value adjustment was fully 
amortized as of December 31, 2019.

Underwriting, Policy Acquisition and Operating Expenses

Underwriting, policy acquisition and operating expenses includes the amortization of commissions, premium taxes and 
underwriting salaries, which are capitalized and deferred over the related workers’ compensation policy period, net of ceding 
commissions earned. The capitalization of underwriting salaries can vary as they are subject to the success rate of our contract 
acquisition efforts. These expenses also include a management fee charged by our Corporate segment, which represents 
intercompany charges pursuant to a management agreement, and the amortization of intangible assets, primarily related to the 
acquisition of Eastern by ProAssurance. The management fee is based on the extent to which services are provided to the 
subsidiary and the amount of premium written by the subsidiary.

The decrease in DPAC amortization for the year ended December 31, 2020 as compared to 2019 primarily reflects the 

decrease in net premiums earned. The decrease in other underwriting and operating expenses for the year ended December 31, 
2020 as compared to 2019 primarily reflected a decrease in travel-related costs and a reduction in employer contributions to the 

94

ProAssurance Savings Plan (see Note 17 of the Notes to Consolidated Financial Statements). The decrease in travel-related 
costs in 2020 are directly attributable to COVID-19, as company business travel has been substantially reduced. The decrease in 
other underwriting and operating expenses in 2020 was largely offset by costs related to the implementation of a new policy 
administration and claims system and one-time costs of $0.9 million primarily comprised of employee severance costs 
associated with the restructuring of our workers' compensation business in 2020.

As previously discussed, alternative market premiums written through our Workers' Compensation Insurance segment's 

alternative market business unit are 100% ceded, less a ceding commission, to either the SPCs in our Segregated Portfolio Cell 
Reinsurance segment or, to a limited extent, an unaffiliated captive insurer. The ceding commission consists of an amount for 
fronting fees, cell rental fees, commissions, premium taxes and risk management fees. The fronting fees, commissions, 
premium taxes and risk management fees are recorded as an offset to underwriting, policy acquisition and operating expenses. 
Cell rental fees are recorded as a component of other income and claims administration fees are recorded as ceded ULAE. The 
decrease in SPC ceding commissions earned for the year ended December 31, 2020 as compared to 2019, primarily reflects the 
decrease in alternative market ceded earned premium.

Segment Results - Segregated Portfolio Cell Reinsurance

The Segregated Portfolio Cell Reinsurance segment includes the results (underwriting profit or loss, plus investment 
results, net of U.S. federal income taxes) of SPCs at Inova Re and Eastern Re, our Cayman Islands SPC operations, as discussed 
in Note 16 of the Notes to Consolidated Financial Statements. SPCs are segregated pools of assets and liabilities that provide an 
insurance facility for a defined set of risks. Assets of each SPC are solely for the benefit of that individual cell and each SPC is 
solely responsible for the liabilities of that individual cell. Assets of one SPC are statutorily protected from the creditors of the 
others. Each SPC is owned, fully or in part, by an agency, group or association and the results of the SPCs are attributable to the 
participants of that cell. We participate to a varying degree in the results of selected SPCs and, for the SPCs in which we 
participate, our participation interest ranges from a low of 20% to a high of 85%. SPC results attributable to external cell 
participants are reflected as an SPC dividend (expense) income in our Segregated Portfolio Cell Reinsurance segment. In 
addition, our Segregated Portfolio Cell Reinsurance segment includes the investment results of the SPCs as the investments are 
solely for the benefit of the cell participants and investment results attributable to external cell participants are reflected in the 
SPC dividend (expense) income. As of December 31, 2020, there were 27 (24 active) SPCs. The SPCs assume workers' 
compensation insurance, healthcare professional liability insurance or a combination of the two from our Workers' 
Compensation Insurance and Specialty P&C segments. As of December 31, 2020, there were two SPCs that assumed both 
workers' compensation insurance and healthcare professional liability insurance and one SPC that assumed only healthcare 
professional liability insurance.

Segment results reflects our share of the underwriting and investment results of the SPCs in which we participate, and

(1) In our December 31, 2019 report on Form 10-K, underwriting, policy acquisition and operating expenses in 2019 included a provision for U.S.
federal  income  taxes  of  $1.1  million  for  SPCs  at  Inova  Re  that  have  elected  to  be  taxed  as  U.S.  taxpayers  (see  Footnote  2).  Since  this  tax 
provision  was  included  as  a  component  of  underwriting,  policy  acquisition  and  operating  expenses  in  2019,  it  was  also  included  in  the 
calculation of the underwriting expense ratio, which increased the 2019 ratio by 1.4 percentage points. Beginning in 2020, this tax provision is 
now  presented  as  a  separate  line  on  our  Consolidated  Statements  of  Income  and  Comprehensive  Income  as  SPC  U.S.  federal  income  tax 
expense as these U.S. federal income taxes do not represent underwriting expenses of the SPCs. We have recast prior periods to conform to this
new presentation, including the calculation of the underwriting expense ratio.

Premiums Written

Premiums in our Segregated Portfolio Cell Reinsurance segment are assumed from either our Workers' Compensation 

Insurance or Specialty P&C segments. Premium volume is driven by five primary factors: (1) the amount of new business 
written, (2) retention of the existing book of business, (3) premium rates charged on the renewal book of business and, for 
workers' compensation business, (4) changes in payroll exposure and (5) audit premium.

Gross Premiums Written

$  72,843  $  87,140  $  (14,297) 

 (16.4%) 

Gross premiums written for the years ended December 31, 2020 and 2019 were primarily comprised of workers' 

compensation coverages assumed from our Workers' Compensation Insurance segment. The decrease in gross premiums 
written in 2020 as compared to 2019 primarily reflected the competitive workers’ compensation market conditions and the 
resulting renewal rate decreases of 4%, retention losses and a decrease in audit premium. The decrease in the retention rate 
during 2020 includes the impact of a reduction in premium funding for a large workers' compensation alternative market 
program. We do not participate in this program; therefore, the reduction in premium funding had no effect on the segment 
results for the year ended December 31, 2020. Healthcare professional liability gross premiums written decreased during 2020 
as compared to 2019 due to retention losses driven by the loss of a large Senior Care policy that chose to utilize self-insurance, 
partially offset by new business (see previous discussion under the heading "Gross Premiums Written" in our Segment Results - 
Specialty Property & Casualty section). We retained 100% of the 22 workers' compensation programs and 3 healthcare 
professional liability programs up for renewal during 2020. During the second quarter of 2020, we added one new alternative 
market program at Inova Re with $1.1 million in premiums written during the year ended December 31, 2020.

Our workers’ compensation premiums written were impacted by reductions in payroll exposure and policy cancellations 
related to the economic impact of COVID-19, and we expect continued downward pressure in future quarters on our workers' 
compensation premium resulting from further reductions in insured payroll exposure; however, the length and magnitude of 
such changes depends on future developments, which are highly uncertain and cannot be predicted.

For the workers' compensation business, each SPC has in place its own external reinsurance arrangements. The healthcare 

professional liability business is assumed net of reinsurance from our Specialty P&C segment; therefore, there are no ceded 
premiums related to the healthcare professional liability business reflected in the table above. The risk retention for each loss 
occurrence for the workers' compensation business ranges from $0.3 million to $0.4 million based on the program, with limits 
up to $119.7 million. In addition, each program has aggregate reinsurance coverage between $1.1 million and $2.1 million on a 
program year basis. Per the SPC external reinsurance agreements, premiums are ceded on a written premium basis. The 
decrease in ceded premiums written in 2020, as compared to 2019, primarily reflected the decrease in workers' compensation 
gross premiums written, partially offset by an increase in reinsurance rates for programs with renewal dates on or after May 1, 
2020. External reinsurance rates vary based on the alternative market program.

The above table reflects ceded premiums as a percent of gross premiums written for the workers' compensation business 

only; healthcare professional liability business is assumed net of reinsurance, as discussed above. The ceded premiums ratio 
reflects the weighted average reinsurance rates of all SPC programs. The increase in the ceded premiums ratio for the year 
ended December 31, 2020 primarily reflects an increase in reinsurance rates for programs renewing on or after May 1, 2020 and 
the reduction in premium funding for a large workers' compensation alternative market program (see previous discussion under 
the heading "Gross Premiums Written"). The reinsurance costs associated with this program are fixed, which resulted in an 
increase in the ceded ratio. 

98

Net Premiums Earned

Net premiums earned consist of gross premiums earned less the portion of earned premiums that the SPCs cede to external 

reinsurers. Because premiums are generally earned pro rata over the entire policy period, fluctuations in premiums earned tend 
to lag those of premiums written. Policies ceded to the SPCs are twelve month term policies and premiums are earned on a pro 
rata basis over the policy period. Net premiums earned also include premium adjustments related to the audit of workers' 
compensation insureds' payrolls. Payroll audits are conducted subsequent to the end of the policy period and any related 
adjustments are recorded as fully earned in the current period.

The decrease in net premiums earned during the year ended December 31, 2020 primarily reflected the pro rata effect of a 

reduction in net premiums written during the preceding twelve months, including the reduction in premium funding for the 
large workers' compensation alternative market program (see previous discussion under the heading "Gross Premiums 
Written").

Net Investment Income and Net Realized Investment Gains (Losses)

Net investment income for the years ended December 31, 2020 and 2019 was primarily attributable to interest earned on 

available-for-sale fixed maturity investments, which primarily includes investment-grade corporate debt securities. We 
recognized $3.1 million of net realized investment gains for the year ended December 31, 2020, which primarily reflected an 
increase in the fair value on our equity portfolio due to an improvement in the global financial markets since the first quarter of 
2020, which was depressed due to the onset of COVID-19. We recognized $4.0 million of net realized investment gains for the 
year ended December 31, 2019 driven by changes in the fair value of our equity portfolio.

Losses and Loss Adjustment Expenses

The following table summarizes the calendar year net loss ratios by separating losses between the current accident year 

and all prior accident years. The current accident year net loss ratio reflected the aggregate loss ratio for all programs. Loss 
reserves are estimated for each program on a quarterly basis. Due to the size of some of the programs, quarterly loss results can 
create volatility in the current accident year net loss ratio to fluctuate significantly from period to period. 

For the year ended December 31, 2019, our Segregated Portfolio Cell Reinsurance segment net loss ratios were affected 

by a $10 million reserve that an SPC at Eastern Re established during the second quarter of 2019. This SPC had previously 
assumed an errors and omissions liability policy that provides coverage for losses up to a lifetime maximum of $10 million 
from a captive insurer unaffiliated with ProAssurance. During the second quarter of 2019, a claim was filed under this policy 
that met the lifetime maximum limit and, accordingly, a $10 million reserve was recorded. We do not participate in the SPC 
that assumed this policy; therefore, these losses were attributable to the external cell participants as reflected in the SPC 
dividend expense (income) and had no effect on our Segregated Portfolio Cell Reinsurance segment results for the year ended 
December 31, 2019. Given the significance of this event, we have removed the impact of the policy from each of the ratios 
below (as shown in the columns labeled "Adjusted") in order to assist in the comparability between periods. Calendar year and 
current accident year net loss ratios for the years ended December 31, 2020 and 2019 was as follows:

Excluding the impact of the errors and omissions liability policy, as previously discussed and as shown in the table above, 

the current accident year net loss ratio increased 2.3 percentage points in 2020 as compared to 2019, primarily reflecting the 
continuation of intense price competition and the resulting renewal rate decreases, partially offset by overall favorable claim 
trends in the 2020 accident year. As a result of the COVID-19 pandemic, legislative and regulatory bodies in certain states have 
changed or are considering changes to compensability requirements and presumptions for certain types of workers related to 
COVID-19 claims. These endeavors could have an adverse impact on the frequency and severity related to COVID-19 claims. 
Furthermore, the current economic conditions resulting from the COVID-19 pandemic have introduced significant risk of a 
prolonged recession, which could have an adverse impact on our return to wellness efforts and the ability of injured workers to 
return to work, resulting in a potential reduction in favorable claim trends in future periods.

Calendar year ceded incurred losses (excluding IBNR) decreased $10.2 million for the year ended December 31, 2020 as 

compared to 2019. Current accident year ceded incurred losses (excluding IBNR) decreased $8.9 million for the year ended 
December 31, 2020 as compared to 2019. The decrease in ceded incurred losses reflects lower severity-related claim activity 
during 2020 and, on a calendar year basis, favorable development on prior year reinsured claims. 

 We recognized net favorable prior year reserve development of $16.5 million and $10.1 million for the years ended 
December 31, 2020 and 2019, respectively. The net favorable prior year reserve development for 2020 included $12.1 million 
related to the workers’ compensation business, which primarily reflected overall favorable trends in claim closing patterns in 
the 2014 through 2019 accident years. In addition, net favorable prior year reserve development in 2020 included $4.4 million 
related to the healthcare professional liability business.

DPAC amortization primarily represents ceding commissions, which vary by program and are paid to our Workers' 

Compensation Insurance and Specialty P&C segments for premiums assumed. Ceding commissions include an amount for 
fronting fees, commissions, premium taxes and risk management fees, which are reported as an offset to underwriting, policy 
acquisition and operating expenses within our Workers' Compensation Insurance and Specialty P&C segments. In addition, 
ceding commissions paid to our Workers' Compensation Insurance segment include cell rental fees which are recorded as other 
income within our Workers' Compensation Insurance segment.

Other underwriting and operating expenses primarily include bank fees, professional fees and bad debt expense. The 

decrease in other underwriting and operating expenses for the year ended December 31, 2020 as compared to 2019 primarily 
reflected recoveries of premiums receivables previously written off, which resulted in an adjustment to our allowance for 
expected credit losses.

Underwriting Expense Ratio (the Expense Ratio)

compared to 2019 was driven by the effect of a reduction in net premiums earned, as previously discussed. Additionally, the 
increase in the expense ratio in 2020 reflected the impact of the reduction in premium funding for a large workers' 

100

compensation alternative market program as the ceding commissions associated with this program are fixed and do not vary 
directly with changes in premium (see previous discussion under the heading "Gross Premiums Written").

SPC U.S. Federal Income Tax Expense

The SPCs at Inova Re have made a 953(d) election under the U.S. Internal Revenue Code and are subject to U.S. federal 

income tax. U.S. federal income taxes incurred totaled $1.7 million and $1.1 million for the years ended December 31, 2020 
and 2019, respectively. The increase in the federal income tax provision for the year ended December 31, 2020 as compared to 
2019 reflects an increase in taxable income for the Inova Re SPCs.

Segment Results - Lloyd's Syndicates

Our Lloyd's Syndicates segment includes the results from our participation in certain Syndicates at Lloyd's of London. In 

addition to our participation in Syndicate results, we have investments in and other obligations to our Lloyd's Syndicates 
consisting of a Syndicate Credit Agreement and FAL requirements. For the 2020 underwriting year, our FAL was comprised of 
investment securities and cash and cash equivalents deposited with Lloyd's which at December 31, 2020 had a fair value of 
approximately $106.2 million, as discussed in Note 3 of the Notes to Consolidated Financial Statements. During the third 
quarter of 2020, we received a return of approximately $32.3 million of cash and cash equivalents from our FAL balances given 
the reduction in our participation in the results of Syndicate 1729 for the 2020 underwriting year to 29% from 61%.

We normally report results from our involvement in Lloyd's Syndicates on a quarter lag, except when information is 

available that is material to the current period. Furthermore, the investment results associated with our FAL investments and 
certain U.S. paid administrative expenses are reported concurrently as that information is available on an earlier time frame.

Lloyd's Syndicate 1729. We provide capital to Syndicate 1729, which covers a range of property and casualty insurance 

and reinsurance lines in both the U.S. and international markets. The remaining capital for Syndicate 1729 is provided by 
unrelated third parties, including private names and other corporate members. As previously discussed, we decreased our 
participation in the results of Syndicate 1729 for the 2020 underwriting year to reduce our exposure and the associated earnings 
volatility. Due to the quarter lag, this reduced participation was not reflected in our results until the second quarter of 2020. 
Syndicate 1729 had a maximum underwriting capacity of £135 million (approximately $185 million based on December 31, 
2020 exchange rates) for the 2020 underwriting year, of which £39 million (approximately $53 million based on December 31, 
2020 exchange rates) was our allocated underwriting capacity. To support and grow our core insurance operations, we 
decreased our participation in the results of Syndicate 1729 for the 2021 underwriting year to 5% from 29% which, due to the 
quarter lag, will not be reflected in our results until the second quarter of 2021. Syndicate 1729's maximum underwriting 
capacity for the 2021 underwriting year is £185 million (approximately $253 million based on December 31, 2020 exchange 
rates), of which £9 million (approximately $13 million based on December 31, 2020 exchange rates) is our allocated 
underwriting capacity.

Lloyd's Syndicate 6131. We provide capital to an SPA, Syndicate 6131, which focuses on contingency and specialty 
property business, primarily for risks within the U.S. as well as international markets. For the 2020 underwriting year, we were 
the sole (100%) capital provider to Syndicate 6131 which had a maximum underwriting capacity of £12 million (approximately 
$16 million based on December 31, 2020 exchange rates). As an SPA, Syndicate 6131 underwrites on a quota share basis with 
Syndicate 1729. Effective July 1, 2020, Syndicate 6131 entered into a six-month quota share reinsurance agreement with an 
unaffiliated insurer. Under this agreement, Syndicate 6131 ceded essentially half of the premium assumed from Syndicate 1729 
to the unaffiliated insurer; the agreement was non-renewed on January 1, 2021 and we decreased our participation in the results 
of Syndicate 6131 to 50% from 100% for the 2021 underwriting year. Due to the quarter lag, this reduced participation will not 
be reflected in our results until the second quarter of 2021. Syndicate 6131's maximum underwriting capacity for the 2021 
underwriting year is £20 million (approximately $27 million based on December 31, 2020 exchange rates), of which £10 
million (approximately $14 million based on December 31, 2020 exchange rates) is our allocated underwriting capacity.

In addition to the results of our participation in Lloyd's Syndicates, as discussed above, our Lloyd's Syndicates segment 
also includes 100% of the results of our wholly owned subsidiaries that support our operations at Lloyd's. For the years ended 
December 31, 2020 and 2019, the results of our Lloyd's Syndicates segment were as follows:

Changes in our premium volume within our Lloyd's Syndicates segment are driven by five primary factors: (1) changes in 

our participation in the Syndicates, (2) the amount of new business and the channels in which the business is written, (3) our 
retention of existing business, (4) the premium charged for business that is renewed, which is affected by rates charged and by 
the amount and type of coverage an insured chooses to purchase and (5) the timing of premium written through multi-period 
policies.

Gross Premiums Written

Gross premiums written in 2020 consisted of property insurance coverages (39% of total gross premiums written), 

casualty coverages (30%), catastrophe reinsurance coverages (13%), specialty property coverages (11%), contingency 
coverages (4%) and property reinsurance coverages (3%). The decrease in gross premiums written in 2020 as compared to 2019 
was driven by our decreased participation in the results of Syndicate 1729, partially offset by volume increases on renewal 
business and renewal pricing increases, primarily on property insurance and casualty coverages, as well as new business 
written, also primarily property insurance and casualty coverages. In addition, gross premiums written in 2020 included a 
binder adjustment on a prior year of account, which reduced written and earned premium in the current period. See further 
discussion on these binder adjustments in our Critical Accounting Estimates section under the heading "Lloyd's Premium 
Estimates."

Ceded Premiums Written

Syndicate 1729 utilizes reinsurance to provide the capacity to write larger limits of liability on individual risks, to provide 
protection against catastrophic loss and to provide protection against losses in excess of policy limits. As previously discussed, 
for the second half of 2020 Syndicate 6131 utilized external quota share reinsurance to manage the net loss exposure on the 
specialty property and contingency coverages it assumed from Syndicate 1729 by ceding essentially half of the premium 
assumed to an unaffiliated insurer; this agreement was non-renewed on January 1, 2021. Due to the quarter lag, the effect of this 
reinsurance arrangement was not reflected in our results until the fourth quarter of 2020. Ceded premiums written decreased for 
the year ended December 31, 2020 as compared to 2019 primarily driven by our decreased participation in the results of 
Syndicate 1729 and, to a lesser extent, the effect of a revision to the Syndicates' estimates of premiums due to reinsurers during 
the first quarter of 2019. The decrease in ceded premiums written in 2020 as compared to 2019 was partially offset by the 
impact of premiums ceded under Syndicate 6131's six-month quota share agreement and, to a lesser extent, an increase in 
estimated reinsurance reinstatement premiums of $1.2 million during the fourth quarter of 2020 triggered by certain property 
and catastrophe related losses exceeding specified levels in the reinsurance agreement.

103

Net Premiums Earned

Net premiums earned consist of gross premiums earned less the portion of earned premiums that the Syndicates cede to 

reinsurers for their assumption of a portion of losses. Premiums written through open-market channels are generally earned pro 
rata over the entire policy period, which is predominately twelve months, whereas premiums written through delegated 
underwriting authority arrangements are earned over twenty-four months. Therefore, net premiums earned is affected by shifts 
in the mix of policies written between the open-market and delegated underwriting authority arrangements. Additionally, net 
premiums earned consists of a mix of policies earned from different open underwriting years. As previously discussed, we 
participate to a varying degree in each open underwriting year which may cause fluctuations in premiums earned. Furthermore, 
fluctuations in premiums earned tend to lag those of premiums written. Premiums for certain policies and assumed reinsurance 
contracts are reported subsequent to the coverage period and/or may be subject to adjustment based on loss experience. These 
premium adjustments are earned when reported, which can result in further fluctuation in earned premium.

Gross, ceded and net premiums earned were as follows:

Year Ended December 31

The decrease in gross premiums earned for the year ended December 31, 2020 as compared to 2019 was driven by our 

decreased participation in Syndicate 1729, which was not reflected in our results until the second quarter of 2020 and, to a 
lesser extent, a binder adjustment which reduced both written and earned premium in the current period (see previous 
discussion under the heading "Gross Premiums Written"). The decrease in gross premiums earned in 2020 was partially offset 
by the pro rata effect of higher premiums written at the Syndicates during the preceding twelve months, primarily property 
insurance and casualty coverages.

The increase in ceded premiums earned during 2020 as compared to 2019 was driven by the aforementioned reinstatement 

premiums earned of $1.2 million during the fourth quarter of 2020 and, to a lesser extent, the pro rata effect of an increase in 
written premiums ceded under reinsurance arrangements during the preceding twelve months, partially offset by our decreased 
participation in Syndicate 1729.

Net Losses and Loss Adjustment Expenses

Losses for the year were primarily recorded using the loss assumptions by risk category incorporated into the business 
plans submitted to Lloyd's for Syndicate 1729 and Syndicate 6131 with consideration given to loss experience incurred to date. 
The assumptions used in each business plan were consistent with loss results reflected in Lloyd's historical data for similar 
risks. The loss ratios may fluctuate due to the mix of earned premium and the timing of earned premium adjustments (see 
discussion in this section under the heading "Net Premiums Earned"). Premium and exposure for some of Syndicate 1729's 
insurance policies and reinsurance contracts are initially estimated and subsequently adjusted over an extended period of time as 
underlying premium reports are received from cedants and insureds. When reports are received, the premium, exposure and 
corresponding loss estimates are revised accordingly. Changes in loss estimates due to premium or exposure fluctuations are 
incurred in the accident year in which the premium is earned.

The following table summarizes calendar year net loss ratios by separating losses between the current accident year and 

all prior accident years. Net loss ratios for the period were as follows:

For the year ended December 31, 2020, the current accident year net loss ratio increased 6.0 percentage points as 

compared to 2019. The increase in the current accident year net loss ratio was driven by certain property and catastrophe related 
losses and, to a lesser extent, contingency related losses incurred during 2020.

104

We recognized $0.6 million and $0.4 million of unfavorable prior year development for the years ended December 31, 
2020 and 2019, respectively. The unfavorable prior year development for the year ended December 31, 2020 was driven by 
higher than expected losses and development on certain large claims, primarily catastrophe related losses, which resulted in 
unfavorable development with respect to a previous year of account.

We have exposures to potential COVID-19 claims through our participation in Syndicates 1729 and 6131. During 2020, 

we recognized losses related to COVID-19 of approximately $3.6 million, net of reinsurance, primarily in Syndicate 6131's 
contingency and Syndicate 1729's casualty books of business. We are closely monitoring potential amendments in legislation 
and court decisions that could impact the claims position; however, to date, legislative attempts have been unsuccessful in most 
territories in which the Syndicates write the majority of their business. See previous discussion in Part I under the heading 
"Insurance Regulatory Matters- COVID-19."

Underwriting, Policy Acquisition and Operating Expenses

Underwriting, policy acquisition and operating expenses decreased by $4.6 million for the year ended December 31, 2020 

as compared to 2019 and reflected our decreased participation in Syndicate 1729 and, to a lesser extent, the effect of higher 
operational expenses incurred associated with establishing Syndicate 6131 during 2019.

For the year ended December 31, 2020, the underwriting expense ratio decreased by 4.0 percentage points as compared to 

2019 driven by lower operating expenses due to our reduced participation in Syndicate 1729, partially offset by a decrease in 
net premiums earned, as previously discussed. Operating expenses incurred during 2020 primarily were related to the 2020 
underwriting year for which our participation is 29%, whereas the net premiums earned during the same period also includes 
premium from other open underwriting years in which we participate at a higher degree.

Investments

The change in net investment income in 2020 as compared to 2019 was primarily attributable to interest earned on our 
FAL investments, which primarily includes investment-grade corporate debt securities. During the second quarter of 2020, 
certain corporate debt securities included in our FAL investments were liquidated. During the third quarter of 2020, 
approximately $32.3 million of cash and cash equivalents was returned to ProAssurance, as previously discussed, which will 
continue to impact the segment's net investment income in future periods. Syndicate 1729's fixed maturities portfolio includes 
certain debt securities classified as trading securities. Investment results associated with these fixed maturity trading securities 
are reported on the same quarter lag.

Taxes

The results of this segment are subject to U.K. income tax law.

Short-term Investments and Other Investments

Short-term investments, which have a maturity at purchase of one year or less are carried at fair value, which 

approximates their cost basis, and are primarily composed of investments in U.S. treasury obligations, commercial paper and 
money market funds. Income from our short-term and other investments decreased during 2020 primarily attributable to lower 
yields given the actions taken by the Federal Reserve to aggressively reduce interest rates in response to COVID-19.

We hold interests in certain LPs/LLCs that generate earnings from trading portfolios, secured debt, debt securities, multi-

strategy funds and private equity investments. The performance of the LPs/LLCs is affected by the volatility of equity and 
credit markets. For our investments in LPs/LLCs, we record our allocable portion of the partnership operating income or loss as 
the results of the LPs/LLCs become available, typically following the end of a reporting period. The decrease in our investment 
results from our portfolio of investments in LPs/LLCs during 2020 as compared to 2019 was due to lower reported earnings 
from several LPs/LLCs driven by the volatility in the global financial markets related to COVID-19.

Our tax credit partnership investments are designed to generate returns in the form of tax credits and tax-deductible 

project operating losses and are comprised of qualified affordable housing project tax credit partnerships and a historic tax 
credit partnership. We account for our tax credit partnership investments under the equity method and record our allocable 
portion of the operating losses of the underlying properties based on estimates provided by the partnerships. For our qualified 
affordable housing project tax credit partnerships, we adjust our estimates of our allocable portion of operating losses 
periodically as actual operating results of the underlying properties become available. Our historic tax credit partnership is 
short-term in nature and the remaining operating losses, up to our total current funded commitment, were recognized during the 
second quarter of 2020. The results from our tax credit partnership investments for the year ended December 31, 2020 reflected 
lower partnership operating losses as compared to 2019. In addition, based on operating results received, we increased our 
estimate of operating losses by $4.3 million and $3.0 million for the years ended December 31, 2020 and 2019, respectively. 

The tax benefits received from our tax credit partnerships, which are not reflected in our investment results above, reduced 

our tax expense in 2020 and 2019 as follows:

were deferred and are expected to be utilized in future periods. See further discussion in Note 5 of the Notes to Consolidated 
Financial Statements.

Tax credits provided by the underlying projects of our historic tax credit partnership are typically available in the tax year 
in which the project is put into active service, whereas the tax credits provided by qualified affordable housing project tax credit 
partnerships are provided over approximately a ten year period.

Non-GAAP Financial Measure – Tax Equivalent Investment Result

We believe that to fully understand our investment returns it is important to consider the current tax benefits associated 

with certain investments as the tax benefit received represents a portion of the return provided by our tax-exempt bonds, BOLI, 
common and preferred stocks, and tax credit partnership investments (collectively, our tax-preferred investments). We impute a 
pro forma tax-equivalent result by estimating the amount of fully-taxable income needed to achieve the same after-tax result as 
is currently provided by our tax-preferred investments. We believe this better reflects the economics behind our decision to 
invest in certain asset classes that are either taxed at lower rates and/or result in reductions to our current federal income tax 
expense. Our pro forma tax-equivalent investment result is shown in the table that follows as well as a reconciliation of our 
GAAP net investment result to our tax equivalent result.

For the year ended December 31, 2020, we recognized $1.5 million of credit-related impairment losses in earnings and a 

nominal amount of non-credit impairment losses in OCI. The credit-related impairment losses recognized in 2020 primarily 
related to corporate bonds in the energy and consumer sectors. Additionally, 2020 included credit-related impairment losses 
related to four corporate bonds in various sectors, which were sold during 2020. The non-credit impairment losses recognized 
during 2020 related to three corporate bonds in the energy and consumer sectors. For the year ended December 31, 2019, we 
recognized credit-related impairment losses in earnings of $0.8 million and a nominal amount of non-credit impairment losses 
in OCI, both of which related to three corporate bonds in the energy and consumer sectors.

We recognized $11.6 million of net realized investment gains for the year ended December 31, 2020, driven primarily by 

realized gains on the sale of certain available-for-sale fixed maturities and equity investments, partially offset by unrealized 
holding losses resulting from decreases in the fair value on our equity portfolio due to the volatility in the global financial 
markets related to COVID-19. For the year ended December 31, 2019, we recognized $55.1 million of net realized investment 
gains driven by both realized gains from the sale of equity investments and unrealized holding gains on our equity portfolio due 
to the improvement in the market since December 31, 2018, which caused our equity securities to increase in value. The most 
significant sectors that benefited from the improvement in the market were the financial and energy sectors.

Operating expenses increased during the year ended December 31, 2020 as compared to 2019 primarily due to an increase 
in professional fees and, to a lesser extent, an increase in share-based compensation expenses. The increase in professional fees 
in 2020 was driven by an increase in transaction-related costs associated with our planned acquisition of NORCAL (see Note 9 
of the Notes to Consolidated Financial Statements) and corporate legal expenses. The increase in share-based compensation 
expenses in 2020 as compared to 2019 was primarily attributable to the effect of a decrease in the value of projected awards 
during 2019 based upon the decline of one of the associated performance metrics. In addition, the increase in operating 
expenses in 2020 as compared to 2019 included one-time costs of $0.5 million primarily comprised of employee severance and 
early retirement benefits granted to certain employees in 2020. The increase in operating expenses in 2020 was partially offset 
by a decrease in various other operational expenses, primarily employer contributions to the ProAssurance Savings Plan (see 
Note 17 of the Notes to Consolidated Financial Statements) and, to a lesser extent, travel-related costs as a result of the 
COVID-19 pandemic.

Operating subsidiaries within our Specialty P&C and Workers' Compensation Insurance segments are charged a 
management fee by the Corporate segment for services provided to these subsidiaries. The management fee is based on the 
extent to which services are provided to the subsidiary and the amount of premium written by the subsidiary. Under the 
arrangement, the expenses associated with such services are reported as expenses of the Corporate segment, and the 
management fees charged are reported as an offset to Corporate operating expenses. While the terms of the arrangement were 
consistent between 2019 and 2020, fluctuations in the amount of premium written by each subsidiary can result in 
corresponding variations in the management fee charged to each subsidiary during a particular period.

* During 2019, we received nominal cash payments associated with our interest rate cap which were recorded as a reduction to
interest expense associated with our Mortgage Loans.

Consolidated interest expense decreased during 2020 as compared to 2019 driven by the change in the fair value of our 

interest rate cap and lower interest expense on our Mortgage Loans. The interest rate cap is designated as an economic hedge of 
interest rate risk associated with our variable rate Mortgage Loans. Our Mortgage Loans accrue interest at three-month LIBOR 
plus 1.325%, and the decrease in interest expense during 2020 as compared to 2019 was primarily due to a decrease in the 
average three-month LIBOR. Interest expense on our Revolving Credit Agreement for the years ended December 31, 2020 and 
2019 primarily reflected unused commitment fees as there were no outstanding borrowings during either period. See further 
discussion of our interest rate cap agreement in Note 2 and further discussion of our outstanding debt in Note 11 of the Notes to 
Consolidated Financial Statements.

Taxes

Tax expense allocated to our Corporate segment includes U.S. tax only, which would include U.S. tax expense incurred 

from our corporate membership in Lloyd's of London. The U.K. tax expense incurred by the U.K. based subsidiaries of our 
Lloyd's Syndicates segment is allocated to that segment. The SPCs at Inova Re, one of our Cayman Islands reinsurance 
subsidiaries, have each made a 953(d) election under the U.S. Internal Revenue Code and are subject to U.S. federal income 
tax; therefore, tax expense allocated to our Corporate segment also includes tax expense incurred from any SPC at Inova Re in 
which we have a participation interest of 80% or greater as those SPCs are required to be included in our consolidated tax 
return. Consolidated tax expense (benefit) reflects the tax expense (benefit) of both segments, as shown in the table below:

(1) Includes tax-exempt interest, dividends received deduction and change in cash surrender value of BOLI.
(2) Represents the tax impact of the impairment of non-deductible goodwill in relation to the Specialty P&C reporting unit during
the third quarter of 2020. See further discussion on the impairment charge under the heading "Goodwill / Intangibles" in the
Critical Accounting Estimates section.

Our effective tax rates for 2020 and 2019, as shown in the table above, resulted in an income tax benefit in both years and 
differs from the statutory federal income tax rate of 21% primarily due to the benefit recognized from the tax credits transferred 
to us from our tax credit partnership investments. Tax credits recognized in 2020 were $17.9 million as compared to 
$21.9 million for 2019. While projected tax credits for 2020 are less than 2019, they continue to have a significant impact on 
the effective tax rate for 2020. Additionally, our effective tax rates in both 2020 and 2019 were impacted by provision-to-return 
differences. For 2020, these differences primarily reflected the additional tax rate differential of 14% on the carryback of the 
2019 NOL to the 2014 tax year which was lower than the previously estimated tax benefit. For 2019, these differences 
primarily reflected a lower amount of tax credits recognized for the 2018 tax year than the previously estimated tax benefit. 
Furthermore, our pre-tax loss in 2020 included a $161.1 million goodwill impairment recognized in relation to the Specialty 
P&C reporting unit during the third quarter of 2020. Of the $161.1 million goodwill impairment, $149.6 million was non-
deductible for which no tax benefit was recognized, while the remaining $11.5 million was deductible for which a 21% tax 
benefit was recognized on the related tax amortization. Consequently, the total impact of the goodwill impairment on the 
effective tax rate in 2020 was approximately 14.5%. See further discussion on this goodwill impairment in Notes 1 and 6 of the 
Notes to Consolidated Financial Statements. Our effective tax rate for the year ended December 31, 2020 also includes the 

111

additional tax rate differential of 14% on the carryback of the 2020 and 2019 NOLs to the 2015 and 2014 tax years, 
respectively, as a result of changes made by the CARES Act to the NOL provisions of the tax law.

(1) Standard Physician premium was our greatest source of premium revenues in both 2019 and 2018 and is predominately
comprised of twelve month term policies. The decrease in twelve month term policies in 2019 was driven by retention
losses, partially offset by an increase in renewal pricing and, to a lesser extent, new business written. The lower retention
in 2019 is largely attributable to our focus on underwriting discipline as we continue to emphasize careful risk selection,
rate  adequacy  and  a  willingness  to  walk  away  from  business  that  does  not  fit  our  goal  of  achieving  a  long-term
underwriting profit. We anticipate a lower than average level of retention to persist as we continue to reevaluate certain
books of business and set our rates to reflect our observations of higher severity trends. Renewal pricing increases in 2019
are  reflective  of  our  concern  about  increases  in  loss  severity.  We  also  offer  twenty-four  month  term  policies  to  our
physician insureds in one selected jurisdiction. The increase in twenty-four month term policies in 2019 as compared to
2018 primarily reflected the normal cycle of renewals (policies subject to renewal in 2019 were previously written in 2017
rather than 2018.

(2) Custom  Physician  premium  includes  large  complex  physician  groups,  multi-state  physician  groups  and  non-standard
physicians and is written primarily on an excess and surplus lines basis. The increase in premium in 2019 as compared to
2018 included timing differences of $5.6 million primarily related to the prior year renewal of certain policies. Excluding
the  effect  of  these  timing  differences,  Custom  Physician  premium  increased  $18.7  million  as  compared  to  2018.  The
remaining increase was primarily due new business written, including the addition of a $7.2 million policy, an increase in

113

exposure related to three policies totaling $5.2 million and, to a lesser extent, renewal price increases. Renewal pricing 
increases during 2019 reflect the rising loss cost environment. The increase in premium in 2019 was partially offset by 
retention  losses  which  reflects  our  focus  on  underwriting  discipline  as  we  continue  to  emphasize  careful  risk  selection, 
rate  adequacy  and  a  willingness  to  walk  away  from  business  that  does  not  fit  our  goal  of  achieving  a  long-term 
underwriting profit. We anticipate a lower than average level of retention to persist as we continue to reevaluate certain 
books of business and set our rates to reflect our observations of higher severity trends.

(3) Hospitals  and  Facilities  premium  (which  includes  hospitals,  surgery  centers  and  miscellaneous  medical  facilities)
increased in 2019 as compared to 2018 primarily due new business written and renewal price increases, largely offset by
retention losses. Renewal pricing increases in 2019 reflect rate increases and contract modifications that we believe are
appropriate given the current loss environment. Retention losses in 2019 were driven by our decision not to renew certain
products and, to a lesser extent, the loss of a $1.4 million policy due to price competition as a result of rate increases. As
we continue to reevaluate certain books of business, we anticipate our retention to remain at a lower than historic level.
(4) Senior Care premium includes facilities specializing in long term residential care primarily for the elderly ranging from
independent living through skilled nursing. Our Senior Care premium decreased in 2019 as compared to 2018 primarily
due  to  retention  losses,  partially  offset  by  new  business  written  and,  to  a  lesser  extent,  renewal  pricing  increases.
Retention losses in 2019 were driven by our decision not to renew certain classes of Senior Care business based on our
expectations of poor loss performance and, to a lesser extent, the loss of a $0.3 million policy as a result of rate increases.
Renewal  price  increases  in  2019  reflect  rate  increases  where  we  believe  appropriate  given  the  loss  environment  in  this
space.

(5) We offer custom alternative risk solutions including loss portfolio transfers for healthcare entities that, most commonly,
are exiting a line of business, changing an insurance approach or simply preferring to transfer risk. In the third quarter of
2019, we entered into a loss portfolio transfer with a regional hospital group which resulted in $0.9 million of retroactive
premium written and fully earned in 2019. In the second quarter of 2018, we entered into a loss portfolio transfer with a
large healthcare organization which resulted in $18.7 million of retroactive premium written and fully earned in 2018. See
further discussion in footnote 7 that follows.

(6) Our Small Business Unit is primarily comprised of premium associated with podiatrists, legal professionals, dentists and
chiropractors.  Our  Small  Business  Unit  premium  decreased  in  2019  as  compared  to  2018  driven  by  retention  losses,
partially  offset  by  an  increase  in  renewal  pricing  and,  to  a  lesser  extent,  new  business  written.  The  increase  in  renewal
pricing was primarily the result of an increase in the rate charged for certain renewed policies in select states.

(7) We offer extended reporting endorsement or "tail" coverage to insureds who discontinue their claims-made coverage with
us,  and  we  also  periodically  offer  tail  coverage  through  custom  policies.  Tail  coverage  premiums  are  generally  100%
earned  in  the  period  written  because  the  policies  insure  only  incidents  that  occurred  in  prior  periods  and  are  not
cancellable. The amount of tail coverage premium written can vary significantly from period to period. The decrease in
tail premiums in 2019 was driven by $7.9 million of tail coverage provided in connection with a loss portfolio transfer
entered  into  during  the  second  quarter  of  2018,  partially  offset  by  $1.8  million  of  tail  coverage  provided  in  connection
with a loss portfolio transfer entered into during the third quarter of 2019.

(8) Our  Medical  Technology  Liability  is  marketed  throughout  the  U.S.;  coverage  is  typically  offered  on  a  primary  basis,
within  specified  limits,  to  manufacturers  and  distributors  of  medical  technology  and  life  sciences  products  including
entities conducting human clinical trials. In addition to the previously listed factors that affect our premium volume, our
medical technology liability premium is impacted by the sales volume of insureds. The increase in 2019 was primarily due
to new business written and, to a lesser extent, an increase in renewal pricing, largely offset by retention losses. Renewal
pricing increases primarily reflect increases in the sales volume and exposure of certain insureds. Retention losses in 2019
are primarily attributable to an increase in competition on terms and pricing.

(9) This  component  of  gross  premiums  written  includes  all  other  product  lines  within  our  Specialty  P&C  segment.  The

increase during 2019 was due to a $1.5 million specialty contractual liability policy.

114

(10) Certain components of our gross premiums written include alternative market premiums. We currently cede either all or a
portion  of  the  alternative  market  premium,  net  of  reinsurance,  to  three  SPCs  of  our  wholly  owned  Cayman  Islands
reinsurance  subsidiaries,  Inova  Re  and  Eastern  Re,  which  are  reported  in  our  Segregated  Portfolio  Cell  Reinsurance
segment. The portion not ceded to the SPCs is retained within our Specialty P&C segment.

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

We believe that we are principally exposed to three types of market risk; interest rate risk, credit risk and equity price risk. 
We have limited exposure to foreign currency risk as we issue few insurance contracts denominated in currencies other than the 
U.S. dollar and we have few monetary assets or obligations denominated in foreign currencies.

Interest Rate Risk

Investments

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. Future 
market interest rates are particularly uncertain at this time given the abrupt interest rate cuts made by the Federal Reserve in 
response to the COVID-19 pandemic. 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 debt security held in an unrealized loss position before its anticipated recovery.

The following tables summarize 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, 2020 and December 31, 2019. There are 
principally two factors that determine interest rates on a given security: changes in the level of yield curves and credit spreads. 
As different asset classes can be affected in different ways by movements in those two factors, we have separated our portfolio 
by asset class in the following tables.

Computations of prospective effects of hypothetical interest rate changes are based on numerous assumptions, including 
the maintenance of the existing level and composition of fixed income security assets, and should not be relied on as indicative 
of future results.

Certain shortcomings are inherent in the method of analysis presented in the computation of the fair value of fixed rate 

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

At December 31, 2020, our fixed maturities portfolio includes fixed maturities classified as trading securities which do not 

have a significant amount of exposure to market interest rates or credit spreads.

Our cash and short-term investments at December 31, 2020 were carried at fair value which approximates their cost basis 

due to their short-term nature. Our cash and short-term investments lack significant interest rate sensitivity due to their short 
duration.

Debt

Our Mortgage Loans are exposed to interest rate risk as they accrue interest at three-month LIBOR plus 1.325%. 

However, a 1% change in LIBOR will not materially impact our annualized interest expense. Additionally, we have 
economically hedged the risk of a change in interest rates in excess of 1% on the Mortgage Loans through the purchase of an 
interest rate cap derivative instrument, which effectively caps our annual interest rate on the Mortgage Loans at a maximum of 
3.675% (see Note 2 of the Notes to Consolidated Financial Statements for additional information). The fair value of the interest 
rate cap is not materially impacted by a 1% change in LIBOR; however, the carrying value of the interest rate cap is impacted 
by future expectations for LIBOR as well as estimations of volatility in the future yield curve.

Our Revolving Credit Agreement is exposed to interest rate risk as it is LIBOR based and a 1% change in LIBOR will 
impact annual interest expense only to the extent that there is an outstanding balance. For every $100 million drawn on our 
Revolving Credit Agreement, a 1% change in interest rates will change our annual interest expense by $1 million. Any 
outstanding balances on the Revolving Credit Agreement can be repaid on each maturity date, which has typically ranged from 
one to three months. As of December 31, 2020, no borrowings were outstanding under our Revolving Credit Agreement.

118

Credit Risk

We have exposure to credit risk primarily as a holder of fixed income securities. We control this exposure by emphasizing 

investment grade credit quality in the fixed income securities we purchase.

As of December 31, 2020, 94% of our fixed maturity securities were rated investment grade as determined by NRSROs, 
such as Fitch, Moody’s and Standard & Poor’s. We believe that this concentration in investment grade securities reduces our 
exposure to credit risk on our fixed income investments to an acceptable level. However, investment grade securities, in spite of 
their rating, can rapidly deteriorate and result in significant losses. Ratings published by the NRSROs are one of the tools used 
to evaluate the creditworthiness of our securities. The ratings reflect the subjective opinion of the rating agencies as to the 
creditworthiness of the securities; therefore, we may be subject to additional credit exposure should the ratings prove to be 
unreliable.

We also have exposure to credit risk related to our premiums receivable and receivables from reinsurers; however, to-date 

we have not experienced any significant amount of credit losses. At December 31, 2020, our premiums receivable was 
approximately $201 million, net of an allowance for expected credit losses of approximately $6 million. See Note 1 of the 
Notes to Consolidated Financial Statements for further information on our allowance for expected credit losses related to our 
premiums receivable. Our receivables from reinsurers (with regard to both paid and unpaid losses) approximated $399 million 
at December 31, 2020 and $403 million at December 31, 2019. We monitor the credit risk associated with our reinsurers using 
publicly available financial and rating agency data. We have not historically experienced material credit losses due to the 
financial condition of a reinsurer, and as of December 31, 2020 our expected credit losses associated with our receivables from 
reinsurers were nominal in amount. During the year ended December 31, 2020, we have received and granted requests for 
premium relief for certain insureds that have been adversely impacted by the recent COVID-19 pandemic in the form of either 
premium credits or premium deferrals. These efforts, along with the recent economic disruptions caused by COVID-19, may 
result in future increases in our allowance for expected credit losses associated with our premiums and reinsurance receivables.

Equity Price Risk

At December 31, 2020, the fair value of our equity investments, excluding our equity investments in bond investment 
funds as discussed in the following paragraph, was $38 million. These equity 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. Disruptions in global financial markets related to 
COVID-19 have resulted in volatility in the fair value of our equity securities during 2020. We cannot predict the level of 
market disruption and subsequent declines in fair value that may occur should the COVID-19 pandemic and its related macro-
economic impacts continue for an extended period of time. The weighted average beta of this group of securities was 1.15. 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 11.5% to $42 million. Conversely, a 10% decrease in the S&P 500 Index would imply a decrease of 
11.5% in the fair value of these securities to $34 million. The selected hypothetical changes of plus or minus 10% do not reflect

ITEM 9A. CONTROLS AND PROCEDURES.

Disclosure Controls

Under the supervision and with the participation of management, including the principal executive and principal financial 
officers, 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, 2020. Based on that evaluation, the principal executive and principal financial 
officers 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 principal executive and 
principal financial officers, 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 principal executive and principal financial officers, we conducted an evaluation of the effectiveness 
of our internal control over financial reporting as of December 31, 2020 based on the framework in Internal Control–Integrated 
Framework issued by the COSO (2013 Framework). Based on that evaluation, our management concluded that our internal 
control over financial reporting was effective as of December 31, 2020 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.

Ernst & Young LLP, an independent registered public accounting firm, has audited the effectiveness of our internal 

controls over financial reporting as of December 31, 2020 as stated in their report which is included elsewhere herein.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of ProAssurance Corporation

Opinion on Internal Control Over Financial Reporting 

We have audited ProAssurance Corporation and subsidiaries’ (the Company) internal control over financial reporting as 
of December 31, 2020, based on criteria established in Internal Control— Integrated Framework issued by the Committee 
of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, 
ProAssurance Corporation and subsidiaries (the Company) maintained, in all material respects, effective internal control 
over financial reporting as of December 31, 2020, based on the COSO criteria.  

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (PCAOB), the consolidated balance sheets as of December 31, 2020 and 2019, the related consolidated statements 
of income and comprehensive income, changes in capital and cash flows for each of the three years in the period ended 
December 31, 2020, and the related notes and financial statement schedules listed in the Index at Item 15(c) (collectively 
referred to as the “financial statements”) of the Company and our report dated February 26, 2021, expressed an 
unqualified opinion thereon.  

Basis for Opinion 

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting 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 are a public accounting firm registered with the PCAOB 
and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and 
the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. 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.  

Definition and Limitations of Internal Control Over Financial Reporting 

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.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of ProAssurance Corporation

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of ProAssurance Corporation and subsidiaries (the 
Company) as of December 31, 2020 and 2019, the related consolidated statements of income, comprehensive income, 
changes in capital and cash flows for each of the three years in the period ended December 31, 2020, and the related notes 
and financial statement schedules listed in the Index at Item 15(c) (collectively referred to as the “consolidated financial 
statements”).  In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated 
financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for 
each of the three years in the period ended December 31, 2020, in conformity with U.S. generally accepted accounting 
principles.  

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2020, based on criteria 
established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (2013 framework), and our report dated February 26, 2021, expressed an unqualified opinion 
thereon. 

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an 
opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the 
PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities 
laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.  

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, 
whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of 
the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such 
procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial 
statements. Our audits also included evaluating the accounting principles used and significant estimates made by 
management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide 
a reasonable basis for our opinion. 

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements 
that was communicated or required to be communicated to the audit committee and that: (1) relate to accounts or 
disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex 
judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated 
financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a 
separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. 

125

Description of 
the Matter

How We 
Addressed the 
Matter in Our 
Audit

Valuation of reserve for losses and loss adjustment expenses

At December 31, 2020, the Company’s gross reserve for losses and loss adjustment expenses was $2.4 
billion. As explained in Notes 1 and 8 to the financial statements, the reserve for losses and loss adjustment 
expenses represents the estimated ultimate costs of all reported and unreported losses and loss adjustment 
expenses incurred and unpaid as of the reporting date. The reserve for losses and loss adjustment expenses is 
determined based on individual claims and payments thereon as well as actuarially determined estimates of 
ultimate losses. The Company updates the data underlying the estimation of the reserve for losses each 
reporting period and adjusts loss estimation assumptions that best reflect emerging data. Both internal and 
consulting actuaries perform an in-depth review of the reserve for losses on at least a semi-annual basis 
using the Company’s loss and exposure data. The actuarial process is highly judgmental, both as to the 
selection of the various actuarial methodologies, and the significant assumptions within those 
methodologies, which are based on historical paid and incurred development trends, and in the interpretation 
of the output of the various methods used.
Auditing management’s reserve for losses and loss adjustment expenses required the involvement of our 
actuarial specialists and was complex and highly judgmental due to sensitivity of the significant assumptions 
which have a significant impact on the valuation of the reserve for losses and loss adjustment expenses.

We obtained an understanding, evaluated the design and tested controls that address the risks of material 
misstatement related to the valuation of the reserve for losses and loss adjustment expenses. This included 
testing management’s controls over the review and approval processes that management has in place for the 
methods and significant assumptions used in estimating the reserve.
To test the reserve for losses and loss adjustment expenses, we performed audit procedures that included, 
among others, evaluating, with the assistance of our actuarial specialists, the Company’s selection of 
methods against those used in prior periods and used in the industry for similar types of insurance. We 
evaluated assumptions, based on historical paid and incurred loss development trends, relative to the 
Company’s historical experience and to the extent required compared to industry experience.  We involved 
our actuarial specialists to independently calculate a range of reasonable losses and loss adjustment expense 
reserve estimates and compared this range to the Company’s recorded reserve for losses and loss adjustment 
expense. We also performed a review of the development of prior years’ reserve estimates.

ProAssurance Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2020

1. Accounting Policies

Organization and Nature of Business

ProAssurance Corporation (ProAssurance, PRA or the Company), a Delaware corporation, is an insurance holding 
company primarily for wholly owned specialty property and casualty and workers' compensation insurance entities including an 
entity that provides capital to Syndicate 1729 and Syndicate 6131 at Lloyd's. Risks insured are primarily liability risks located 
within the U.S.

ProAssurance operates in five reportable segments as follows: Specialty P&C, Workers' Compensation Insurance, 
Segregated Portfolio Cell Reinsurance, Lloyd's Syndicates and Corporate. For more information on the Company's segment 
reporting, including the nature of products and services provided and financial information by segment, refer to Note 16.

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. ProAssurance subsidiaries located in the U.K. are normally reported on a quarter lag due to timing 
issues regarding the availability of information, except when information is available that is material to the current period. 
Furthermore, investment results associated with ProAssurance's FAL investments and certain U.S. paid administrative expenses 
are reported concurrently as that information is available on an earlier time frame.

Reclassifications

In ProAssurance's December 31, 2019 and 2018 reports on Form 10-K, underwriting, policy acquisition and operating 

expenses for the years ended December 31, 2019 and 2018 included a provision for U.S. federal income taxes of $1.1 million 
and $0.4 million, respectively, for SPCs at Inova Re reported in the Company's Segregated Portfolio Cell Reinsurance segment 
that elected to be taxed as U.S. taxpayers. Beginning in 2020, this tax provision is now presented as a separate line item on the 
Consolidated Statements of Income and Comprehensive Income as SPC U.S. federal income tax expense. To conform to the 
current year presentation, ProAssurance has recast underwriting, policy acquisition and operating expenses for the years ended 
December 31, 2019 and 2018 on the Consolidated Statements of Income and Comprehensive Income as well as in the financial 
results by segment in Note 16.

Certain other insignificant prior year amounts have been reclassified to conform to the current year presentation.

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.

Accounting Policies

The significant accounting policies followed by ProAssurance in making estimates that materially affect financial 
reporting are summarized in these Notes to Consolidated Financial Statements. The Company evaluates these estimates and 
assumptions on an ongoing basis based on current and historical developments, market conditions, industry trends and other 
information that the Company believes to be reasonable under the circumstances. The Company can make no assurance that 
actual results will conform to its estimates and assumptions; reported results of operations may be materially affected by 
changes in these estimates and assumptions.

As a result of the COVID-19 pandemic, the Company is reevaluating certain of these estimates and assumptions which 

could result in material changes to its results of operations including, but not limited to, higher losses and loss adjustment 
expenses, lower premium volume, asset impairment charges, declines in investment valuations, reductions in audit premium 
estimates, deferred tax valuation allowances and increases in the allowance for expected credit losses related to available-for-
sale securities, premiums receivable and reinsurance receivables. The extent to which the COVID-19 pandemic impacts the 
Company's business, results of operations and financial condition will depend on future developments, which are highly 
uncertain and cannot be predicted. These factors include, but are not limited to, the duration, spread, severity, reemergence or 
mutation of the COVID-19 pandemic, development and wide-scale distribution of medicines or vaccines that effectively treat 

132

ProAssurance Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2020

the virus, the effects of the COVID-19 pandemic on the Company's insureds, the loss environment, the healthcare industry, the 
labor market and Lloyd's, the actions and stimulus measures taken by governments and governmental agencies, and to what 
extent normal economic and operating conditions can resume. Even after the COVID-19 pandemic has subsided, the Company 
may experience an impact to its business as a result of any economic recession that has occurred or may occur in the future.

Recognition of Revenues

Insurance premiums are recognized as revenues pro rata over the terms of the policies, which are principally one year in 

duration. 

Credit Losses

ProAssurance's premiums receivable and reinsurance receivables are exposed to credit losses but to-date have not 
experienced any significant amount of credit losses. ProAssurance measures expected credit losses on its premiums receivables 
and reinsurance receivables on a collective (pool) basis when similar risk characteristics exist, and the Company will reassess 
its pools each reporting period to ensure all receivables within the pool continue to share similar risk characteristics. If the 
Company determines that a receivable does not share risk characteristics with its other receivables within a pool, it will evaluate 
that receivable for expected credit losses on an individual basis. ProAssurance measures expected credit losses associated with 
its premium receivables at the segment level as each segment’s premium receivables share similar risk characteristics including 
term, type of financial asset and similar historical and expected credit loss patterns. ProAssurance measures expected credit 
losses associated with its reinsurance receivables (related to both paid and unpaid losses) at the consolidated level as its 
reinsurance receivables share similar risk characteristics including type of financial asset, type of industry and similar historical 
and expected credit loss patterns.

ProAssurance measures expected credit losses over the contractual term of each pool utilizing a loss rate method. 
Historical internal credit loss experience for each pool is the basis for the Company’s assessment of expected credit losses; 
however, the Company may also consider historical credit loss information from external sources. In addition to historical 
credit loss data, the Company also considers reasonable and supportable forecasts of future economic conditions in its estimate 
of expected credit losses by utilizing industry and macroeconomic factors that it believes most relevant to the collectability of 
each pool. 

ProAssurance's premiums receivable on its Consolidated Balance Sheet as of December 31, 2020 and 2019 is reported net 
of the related allowance for expected credit losses of $6.1 million and $1.6 million, respectively. The following tables present a 
roll forward of the allowance for expected credit losses related to the Company's premiums receivable for the year ended 
December 31, 2020.

ProAssurance's expected credit losses associated with its reinsurance receivables (related to both paid and unpaid losses) 
were nominal in amount as of December 31, 2020. ProAssurance has other financial assets and off-balance-sheet commitments 
that are exposed to credit losses; however, expected credit losses associated with these assets and commitments were nominal in 
amount as of December 31, 2020.

Earned But Unbilled Premiums

Workers’ compensation premiums are determined based upon the payroll of the insured, the applicable premium rates and 

an experience-based modification factor, where applicable. An audit of the policyholders’ records is conducted after policy 
expiration to make a final determination of applicable premiums. Audit premium due from or due to a policyholder as a result 
of an audit is reflected in net premiums written and earned when billed. ProAssurance tracks, by policy, the amount of 
additional premium billed in final audit invoices as a percentage of payroll exposure and uses this information to estimate the 

133

ProAssurance Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2020

probable additional amount of EBUB as of the balance sheet date. Changes to the EBUB estimate are included in net premiums 
written and earned in the period recognized. As of December 31, 2020 and 2019, ProAssurance carried EBUB of $3.0 million 
and $4.3 million, respectively, as a part of premiums receivable. As a result of the economic impact of COVID-19, the 
Company expects future reductions in payroll exposure related to in-force policies that could result in a significant decrease in 
audit premium and our EBUB estimate. ProAssurance will continue to monitor and adjust the estimate, if necessary, based on 
changes in insured payrolls and economic conditions, as experience develops or new information becomes known; however, the 
length and magnitude of such changes depends on future developments, which are highly uncertain and cannot be predicted. 

Losses and Loss Adjustment Expenses

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

 Management establishes the reserve for losses after taking into consideration a variety of factors including premium rates, 

historical paid and incurred loss development trends, and management's evaluation of the current loss environment including 
frequency, severity, the expected effect of inflation, general economic and social trends, and the legal and political 
environment. Management also takes into consideration the conclusions reached by internal and consulting actuaries. 
Management updates and reviews the data underlying the estimation of the reserve for losses each reporting period and makes 
adjustments to loss estimation assumptions that best reflect emerging data. Both internal and consulting actuaries perform an in-
depth review of the reserve for losses on at least a semi-annual basis using the loss and exposure data of ProAssurance's 
subsidiaries. Consulting actuaries provide reports to management regarding the adequacy of reserves.

Estimating casualty insurance reserves, and particularly long-tailed insurance reserves, is a complex process. Long-tailed 
insurance is characterized by the extended period of time typically required both to assess the viability of a claim and potential 
damages, if any, and to reach a resolution of the claim. For a high proportion of the risks insured or reinsured by ProAssurance, 
the period of time required to resolve a claim is often five years or more, and claims may be subject to litigation. Estimating 
losses for these long-tailed 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 current operations. Due to the size of 
ProAssurance’s reserve for losses, even a small percentage adjustment to these estimates could have a material effect on 
earnings in the period in which the adjustment is made, as was the case in 2020, 2019 and 2018.

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 certain policies issued by ProAssurance. In return, ProAssurance agrees to pay a premium to the reinsurer. 
ProAssurance uses reinsurance to provide capacity to write larger limits of liability, to provide reimbursement for losses 
incurred under the higher limit coverages the Company offers, to provide protection against losses in excess of policy limits, 
and, in the case of risk sharing arrangements, to align the Company's objectives with those of its strategic business partners and 
to provide custom insurance solutions for large customer groups.

Receivable from reinsurers on paid losses and LAE is the estimated amount of losses already paid that will be recoverable 
from reinsurers. Receivable from reinsurers on unpaid losses and LAE 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 ultimate 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 

134

ProAssurance Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2020

reinsurers, an adjustment to these estimates could have a material effect on ProAssurance's results of operations for the period 
in which the adjustment is made.

Reinsurance contracts do not relieve ProAssurance from its obligations to policyholders. ProAssurance continually 
monitors its reinsurers to minimize its exposure to significant credit losses from reinsurer insolvencies (see previous discussion 
under the heading "Credit Losses"). Any amount determined to be uncollectible is written off in the period in which the 
uncollectible amount is identified. See Note 4 for further information.

Retroactive Insurance Contracts

In certain instances, ProAssurance’s insurance contracts cover losses both on a prospective basis and retroactive basis, and 

accordingly, ProAssurance bifurcates the prospective and retroactive provisions of these contracts and accounts for each 
component separately, where practicable.

Under the retroactive provisions of a contract, all premiums received and losses assumed are recognized immediately in 

earnings at the inception of the contract as all of the underlying loss events occurred in the past. If the estimated losses assumed 
differ from the premium received related to the retroactive provision of a contract, the resulting difference is deferred and 
recognized over the estimated claim payment period with the periodic amortization reflected in earnings as a component of net 
losses and LAE. Deferred gains are included as a component of the reserve for losses and LAE, and deferred losses are included 
as a component of other assets on the Consolidated Balance Sheet. Subsequent changes to the estimated timing or amount of 
future loss payments in relation to the losses assumed under retroactive provisions also produce changes in deferred balances. 
Changes in such estimates are applied retrospectively, and the resulting changes in deferred balances, together with periodic 
amortization, are included in earnings in the period of change.

Lloyd’s Premium Estimates

For certain insurance policies and reinsurance contracts written in the Lloyd’s Syndicates segment, premiums are initially 

recognized based upon estimates of ultimate premium. Estimated ultimate premium consists primarily of premium written 
under delegated underwriting authority arrangements, which consist primarily of binding authorities, and certain assumed 
reinsurance agreements. These estimates of ultimate premium are judgmental and are dependent upon certain assumptions, 
including historical premium trends for similar agreements. As reports are received from programs, ultimate premium estimates 
are revised, if necessary, with changes reflected in current operations.

Deferred Policy Acquisition Costs; Ceding Commission Income

Costs that vary with and are directly related to the successful production of new and renewal premiums (primarily 
premium taxes, commissions and underwriting salaries) are deferred to the extent they are recoverable against unearned 
premiums and are amortized as related premiums are earned. Unearned ceding commission income is reported as an offset to 
DPAC, and ceding commission earned is reported as an offset to DPAC amortization.

ProAssurance evaluates the recoverability of DPAC typically at the segment level each reporting period, or in a manner 
that is consistent with the way the Company manages its business. Any amounts estimated to be unrecoverable are charged to 
expense in the current period. As part of the evaluation of the recoverability of DPAC, ProAssurance also evaluates unearned 
premium for premium deficiencies. A premium deficiency is recognized if the sum of anticipated losses and loss adjustment 
expenses, unamortized DPAC and maintenance costs, net of anticipated investment income, exceeds the related unearned 
premium. If a premium deficiency is identified, the associated DPAC is written off, and a PDR is recorded for the excess 
deficiency as a component of net losses and loss adjustment expenses in the Consolidated Statement of Income and 
Comprehensive Income and as a component of the reserve for losses on the Consolidated Balance Sheet.

Investments

Recurring Fair Value Measurements

Fair values of investment securities are primarily provided by independent pricing services. The pricing services provide 

an exchange-traded price, if available, or provide an estimated price determined using multiple observable inputs, including 
exchange-traded prices for similar assets. Management reviews valuations of securities obtained from the pricing services for 
accuracy based upon the specifics of the security, including class, maturity, credit rating, durations, collateral and comparable 
markets for similar securities. Multiple observable inputs are not available for certain of the Company's investments, including 
corporate debt not actively traded, certain asset-backed securities and investments in LPs/LLCs. Management values the 

135

ProAssurance Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2020

corporate debt not actively traded and the other asset-backed securities either using dealer quotes for similar securities or 
discounted cash flow models using yields currently available for similar securities. Management values certain investment 
funds, primarily LPs/LLCs, based on the NAV of the interest held, as provided by the fund.

Nonrecurring Fair Value Measurements

Management measures the fair value of certain assets on a nonrecurring basis when events or changes in circumstances 
indicate that the carrying amount of the assets may not be recoverable. These assets include investments carried principally at 
cost, investments in tax credit partnerships, fixed assets, goodwill and other intangible assets. These assets would also include 
any equity method investments that do not provide a NAV.

Fixed Maturities

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

Available-for-sale securities are carried at fair value, determined as described above and in Note 2. Exclusive of 

impairment losses, discussed in a separate section that follows, unrealized holding gains and losses on available-for-sale 
securities are included, net of related tax effects, as a component of OCI in the Consolidated Statement of Income and 
Comprehensive Income during the period of change and as a component AOCI in shareholders' equity on the Consolidated 
Balance Sheet.

Investment income includes amortization of premium and accretion of discount related to available-for-sale debt securities 

acquired at other than par value. Debt securities and mandatorily redeemable preferred stock with maturities beyond one year 
when purchased are classified as fixed maturities.

Trading securities are carried at fair value, determined as described above, with the unrealized holding gains and losses 

included as a component of net realized investment gains (losses) in the Consolidated Statement of Income and Comprehensive 
Income during the period of change.

Equity Investments

Equity investments are carried at fair value, as described above, with the holding gains and losses included as a 
component of net realized investment gains (losses) in the Consolidated Statement of Income and Comprehensive Income 
during the period of change. Equity investments are primarily comprised of stocks, bond funds and investment funds.

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, commercial paper and money market funds. All balances are carried at fair value which 
approximates the cost of the securities due to their short-term nature.

Other Investments

Investments in convertible bond securities are carried at fair value as permitted by the accounting guidance for hybrid 
financial instruments, with changes in fair value recognized in income as a component of net realized investment gains (losses) 
during the period of change. Interest on convertible bond securities is recorded on an accrual basis based on contractual interest 
rates and is included in net investment income.

Investment in Unconsolidated Subsidiaries

Equity investments, primarily investments in LPs/LLCs, where ProAssurance is deemed to have influence because it 
holds a greater than a minor interest are accounted for using the equity method. Under the equity method, the recorded basis of 
the investment is adjusted each period for the investor’s pro rata share of the investee’s income or loss. Investments in 
unconsolidated subsidiaries include tax credit partnerships accounted for using the equity method, whereby ProAssurance’s 
proportionate share of income or loss is included in equity in earnings (loss) of unconsolidated subsidiaries. Tax credits 
received from the partnerships are recognized in the period received in the Consolidated Statement of Income and 
Comprehensive Income as either a reduction to current tax expense or as a component of deferred tax expense if they cannot be 
utilized in the period received.

136

ProAssurance Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2020

Business Owned Life Insurance

ProAssurance owns life insurance contracts on certain management employees. The life insurance contracts are carried at 

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

Realized Gains and Losses

Realized investment gains and losses are recognized on the first-in, first-out basis for GAAP purposes and on the specific 

identification basis for tax purposes.

Impairments

ProAssurance evaluates its available-for-sale investment securities, which at December 31, 2020 and 2019 consisted 

entirely of fixed maturity securities, on at least a quarterly basis for the purpose of determining whether declines in fair value 
below recorded cost basis represent a credit loss. The Company considers a credit loss to have occurred:

• if there is intent to sell the security;
• if it is more likely than not that the security will be required to be sold before full recovery of its amortized cost

basis; or

• if the entire amortized basis of the security is not expected to be recovered.

The assessment of whether the amortized cost basis of a security is expected to be recovered requires the Company to 

make assumptions regarding various matters affecting future cash flows. The choice of assumptions is subjective and requires 
the use of judgment. Actual credit losses experienced in future periods may differ from the Company’s estimates of those credit 
losses. Methodologies used to estimate the present value of expected cash flows are:

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 various factors in projecting recovery values and 
recovery time frames, including the following:

• 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;

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

issuer;

• 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;

• 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 ProAssurance's 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;
• adverse legal or regulatory events;
• significant deterioration in the market environment that may affect the value of collateral (e.g. decline in real estate

prices);

• significant deterioration in economic conditions; and
• disruption in the business model resulting from changes in technology or new entrants to the industry.

If deemed appropriate and necessary, a discounted cash flow analysis is performed to confirm whether a credit loss exists 

and, if so, the amount of the credit loss. ProAssurance uses the single best estimate approach for available-for-sale debt 
securities and considers all reasonably available data points, including industry analyses, credit ratings, expected defaults and 
the remaining payment terms of the debt security. For fixed rate available-for-sale debt securities, cash flows are discounted at 
the security's effective interest rate implicit in the security at the date of acquisition. If the available-for-sale debt security’s 
contractual interest rate varies based on subsequent changes in an independent factor, such as an index or rate, for example, the 
prime rate, the LIBOR, or the U.S. Treasury bill weekly average, that security’s effective interest rate is calculated based on the 
factor as it changes over the life of the security.

If ProAssurance intends to sell a debt security or believes it will more likely than not be required to sell a debt security 
before the amortized cost basis is recovered, any existing allowance will be written off against the security's amortized cost 

137

basis, with any remaining difference between the debt security's amortized cost basis and fair value recognized as an 
impairment loss in earnings.

Exclusive of securities where there is an intent to sell or where it is not more likely than not that the security will be 

required to be sold before recovery of its amortized cost basis, impairment for debt securities is separated into a credit 
component and a non-credit component. The credit component of an impairment is the difference between the security’s 
amortized cost basis and the present value of its expected future cash flows, while the non-credit component is the remaining 
difference between the security’s fair value and the present value of expected future cash flows. An allowance for expected 
credit losses will be recorded for the expected credit losses through income and the non-credit component is recognized in OCI. 
The amount of impairment recognized is limited to the excess of the amortized cost over the fair value of the available-for-sale 
debt security.

Derivatives

ProAssurance records derivative instruments at fair value in the Consolidated Balance Sheets. ProAssurance accounts for 
the changes in fair value of derivatives depending on whether the derivative is designated as a hedging instrument and if so, the 
type of hedging relationship. For derivative instruments not designated as hedging instruments, ProAssurance recognizes the 
change in fair value of the derivative in earnings during the period of change. As of December 31, 2020, ProAssurance has not 
designated any derivative instruments as hedging instruments and does not use derivative instruments for trading purposes.

Foreign Currency

The functional currency of all ProAssurance foreign subsidiaries is the U.S. dollar. In recording foreign currency 
transactions, revenue and expense items are converted to U.S. dollars at the exchange rate prevailing at the transaction date. 
Monetary assets and liabilities originating in currencies other than the U.S. dollar are remeasured to U.S. dollars at the rates of 
exchange in effect as of the balance sheet date. The resulting foreign currency gains or losses are recognized in the 
Consolidated Statements of Income and Comprehensive Income as a component of other income. Monetary assets and 
liabilities include investments, cash and cash equivalents, accrued expenses and other liabilities. In addition, monetary assets 
and liabilities include certain premiums receivable and reserve for losses and LAE as a result of reinsurance transactions 
conducted with foreign cedants denominated in their local functional currencies. 

Cash and Cash Equivalents

For purposes of the Consolidated Balance Sheets and Consolidated Statements of Cash Flows, ProAssurance considers all 

demand deposits and overnight investments to be cash equivalents.

Income Taxes/Deferred Taxes

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

components of tax expense.

ProAssurance evaluates tax positions taken on tax returns and recognizes positions in the financial statements when it is 

more likely than not that the position will be sustained upon resolution with a taxing authority. If recognized, the benefit is 
measured as the largest amount of benefit that has a greater than fifty percent probability of being realized. Uncertain tax 
positions are reviewed each period by considering changes in facts and circumstances, such as changes in tax law, interactions 
with taxing authorities and developments in case law, and adjustments would be made if considered necessary. Adjustments to 
unrecognized tax benefits may affect income tax expense, and the settlement of uncertain tax positions may require the use of 
cash. Other than differences related to timing, no significant adjustments were considered necessary during the years ended 
December 31, 2020 or 2019. 

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 and advanced premiums, DPAC, compensation related items, 
tax credit carryforwards, unrealized investment gains (losses) and basis differentials in fixed assets, intangible assets and 
operating leases and investments. Deferred tax assets and liabilities are measured using the enacted tax rates expected to be in 
effect when such benefits are realized. ProAssurance reviews its deferred tax assets quarterly for impairment. If management 
determines that it is more likely than not that some or all of a deferred tax asset will not be realized, a valuation allowance is 
recorded to reduce the carrying value of the asset. In assessing the need for a valuation allowance, management is required to 
make certain judgments and assumptions about the future operations of ProAssurance based on historical experience and 

138

ProAssurance Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2020

information as of the measurement period regarding reversal of existing temporary differences, carryback capacity, future 
taxable income of the appropriate character, including its capital and operating characteristics, and tax planning strategies.

A valuation allowance has been established against the full value of the deferred tax asset related to the NOL 
carryforwards for the U.K. operations and against a portion of the deferred tax asset related to the U.S. state NOL 
carryforwards. Management concluded that it was more likely than not that these deferred tax assets will not be realized. 
ProAssurance has also established a valuation allowance against the deferred tax assets of certain SPCs at its wholly owned 
Cayman Islands reinsurance subsidiary, Inova Re, as these SPCs are in a cumulative pre-tax loss position, and management 
concluded that a valuation allowance was required based upon the weight of this negative evidence. See further discussion in 
Note 5.

Leases

ProAssurance is involved in a number of leases, primarily for office facilities. The Company determines if an arrangement 

is a lease at the inception date of the contract and classifies all leases as either financing or operating. Operating leases are 
included in operating lease ROU assets and operating lease liabilities on the Consolidated Balance Sheet. The ROU asset 
represents the right to use the underlying asset for the lease term. As of December 31, 2020, ProAssurance has no leases that are 
classified as financing leases.

Operating ROU assets and operating lease liabilities are initially recognized as of the lease commencement date based on 
the present value of the remaining lease payments, discounted over the term of the lease using a discount rate determined based 
on information available as of the commencement date. As the majority of ProAssurance's lessors do not provide an implicit 
discount rate, the Company uses its collateralized incremental borrowing rate in determining the present value of remaining 
lease payments. Due to the adoption of ASU 2016-02, the Company used its collateralized incremental borrowing rate as of 
January 1, 2019 for operating leases that commenced prior to that date. Subsequent to the initial recognition, the operating ROU 
asset and operating lease liability are amortized and accreted, respectively, over the lease term in a manner that results in a 
straight-line operating lease expense. Operating lease expense is included as a component of operating expense on the 
Consolidated Statements of Income and Comprehensive Income for the year ended December 31, 2020 and 2019. Leases with 
an initial term of twelve months or less are considered short-term and are not recorded on the Consolidated Balance Sheet; lease 
expense for these leases is also recognized on a straight-line basis over the lease term. Additionally, for leases entered into or 
reassessed after the adoption of ASU 2016-02 on January 1, 2019, ProAssurance accounts for lease and non-lease components 
of a contract as a single lease component.

Operating lease ROU assets are evaluated for impairment at the asset group level whenever events or changes in 
circumstances indicate that the carrying amount of the asset group may not be recoverable. The carrying amount of an asset 
group, which includes the operating lease ROU asset and the related operating lease liability, is not recoverable if the carrying 
amount exceeds the sum of the undiscounted cash flows expected to result from the use of the asset group over the life of the 
primary asset in the asset group. That assessment is based on the carrying amount of the asset group, including the operating 
lease ROU asset and the related operating lease liability, at the date it is tested for recoverability and an impairment loss is 
measured and recognized as the amount by which the carrying amount of the asset group exceeds its fair value. Any impairment 
loss is allocated to each asset in the asset group, including the operating ROU asset.

When a lease of an office facility is to be abandoned and will not be subleased, the Company first evaluates whether or 
not the operating lease ROU asset’s inclusion in an existing asset group continues to be appropriate and if the commitment to 
abandon the lease constitutes a change in circumstances requiring the operating lease ROU asset, or the larger asset group, to be 
tested for impairment. If an impairment test is required, it is performed in the same manner as discussed above. Any remaining 
carrying value of the operating lease ROU asset is amortized from the date the Company commits to a plan to abandon the lease 
to the expected date that the Company will cease to use the leased property. Leases to be abandoned in which the Company has 
the intent or practical ability to sublease continue to be accounted for under a held and use model, with no change to the 
amortization period of the operating lease ROU asset, and are evaluated for impairment as a separate asset group at the date the 
sublease is executed.

Real Estate

Real Estate balances are reported at cost or, for properties acquired in business combinations, estimated fair value on the 

date of acquisition, less accumulated depreciation. Real estate principally consists of properties in use as corporate offices. 
Depreciation is computed over the estimated useful lives of the related property using the straight-line method. Excess office 
capacity is leased or made available for lease; rental income is included in other income, and real estate expenses are included 
in operating expense.

Real estate accumulated depreciation was approximately $26.5 million and $25.7 million at December 31, 2020 and 2019, 
respectively. Real estate depreciation expense was $0.9 million, $1.0 million and $1.2 million for the years ended December 31, 
2020, 2019 and 2018, respectively.

Goodwill/Intangibles

Intangible Assets

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

primarily consist of policyholder relationships, renewal rights and trade names. Intangible assets with an indefinite life, 
primarily state licenses, are not amortized. Indefinite lived intangible assets are evaluated for impairment on an annual basis or 
upon the occurrence of certain triggering events or substantive changes in circumstances that indicate the intangible asset may 
be impaired. Amortizable intangible assets and other long-lived assets are tested for impairment at the asset group level upon 
the occurrence of certain triggering events or substantive changes in circumstances that indicate the carrying amount of the 
asset group may not be recoverable. An impairment loss is recognized when estimated undiscounted future cash flows expected 
to result from the use of the asset group are less than the carrying amounts of the related asset group. Impairment losses are 
measured as the amount by which the carrying amount of the asset groups exceed their fair values. The Company's asset groups 
generally correspond to the same level at which goodwill is tested for impairment. The following table provides additional 
information regarding ProAssurance's intangible assets.

2025.

Goodwill

Goodwill is tested for impairment annually or more frequently if circumstances indicate an impairment may have 

occurred. The date of the Company's annual goodwill impairment testing is October 1.

Impairment of goodwill is tested at the reporting unit level, which is consistent with the Company's reportable segments 

identified in Note 16 of the Notes to Consolidated Financial Statements.

During the third quarter of 2020, the Company recorded a goodwill impairment charge of $161.1 million, and the facts 

and circumstances that led to this impairment and how the fair value of each reporting unit was estimated, including the 
significant assumptions used and other details are outlined in the following section.

Interim Impairment Assessments

As disclosed in the Company's June 30, 2020 report on Form 10-Q, COVID-19 has caused significant market volatility 

impacting its actual and projected results along with a decline in the Company's stock price; and the Company performed a 
quantitative assessment on the Specialty P&C and Workers' Compensation Insurance reporting units. As a result of the interim 
goodwill impairment assessment in the second quarter of 2020, management concluded that the fair value of each of the 
Specialty P&C and Workers' Compensation Insurance reporting units were greater than their carrying value as of the testing 
date; therefore, goodwill was not impaired and no further impairment testing was required at that time. 

140

ProAssurance Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2020

As the impacts persisted into the third quarter, management performed new quantitative assessments of goodwill on the 

Company's Specialty P&C and Workers' Compensation Insurance reporting units using updated marketplace data. The updated 
data, which was significantly influenced by the Company's continued depressed stock price relative to both the Company's book 
value and the comparable stock prices of its peers, impacted a number of key variables in the Company's analysis including the 
determination of a higher discount rate and lower valuation multiples. In addition, new guidance given by the Federal Reserve 
during the period regarding the expectation of a prolonged low interest rate environment impacted the Company's analysis. This 
analysis during the third quarter of 2020 indicated an impairment of the goodwill associated with the Company's Specialty P&C 
reporting unit and accordingly the Company recorded a $161.1 million charge to goodwill during the third quarter of 2020.

For each of the interim impairment assessments performed in the second and third quarters of 2020, management 

estimated the fair value of the reporting units using both an income approach and a market approach using marketplace data that 
was current at the time of each respective analysis. The estimate of fair value derived from the income approach was based on 
the present value of expected future cash flows, including terminal value, utilizing a market-based weighted average cost of 
capital determined separately for each reporting unit. The estimate of fair value derived from the market approach was based on 
price to book multiple data. The determination of fair value involved the use of significant estimates and assumptions, including 
revenue growth rates, operating margins, capital requirements, tax rates, terminal growth rates, discount rates, comparable 
public companies and synergistic benefits available to market participants. In addition, management made certain judgments 
and assumptions in allocating shared assets and liabilities to individual reporting units to determine the carrying amount of each 
reporting unit. 

Management also performed impairment tests of certain of the Company's definite and indefinite lived intangible assets 

for which a triggering event was deemed to have occurred, as discussed above. Based upon these impairment tests, no 
impairment of ProAssurance's definite or indefinite lived intangible assets was identified at September 30, 2020.

Annual Impairment Assessment

Subsequent to performing the aforementioned interim impairment assessments, the Company performed its annual 

goodwill impairment assessment as of October 1, 2020.

When testing goodwill for impairment on the Company's annual test date, it has the option to first assess qualitative 
factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that 
the estimated fair value of a reporting unit is less than its carrying amount. If the Company elects to perform a qualitative 
assessment and determine that an impairment is more likely than not, the Company is then required to perform a quantitative 
impairment test; otherwise, no further analysis is required. The Company also may elect not to perform the qualitative 
assessment and, instead, proceed directly to the quantitative impairment test.

Performance of the qualitative goodwill impairment assessment requires judgment in identifying and considering the 
significance of relevant key factors, events, and circumstances that affect the fair values of the Company's reporting units. This 
requires consideration and assessment of external factors such as macroeconomic, industry, and market conditions, as well as 
entity-specific factors, such as the Company's actual and planned financial performance. The Company also gives consideration 
to the difference between each reporting unit's fair value and carrying value as of the most recent date that a fair value 
measurement was performed. If the results of the qualitative assessment conclude that it is not more likely than not that the fair 
value of a reporting unit exceeds its carrying value, additional quantitative impairment testing is performed. 

The quantitative goodwill impairment test involves comparing the fair value of a reporting unit with its carrying value 
including goodwill. If the fair value of a reporting unit exceeds its carrying value, the reporting unit's goodwill is considered not 
to be impaired. However, if the carrying value of a reporting unit exceeds its fair value, an impairment loss is recorded in an 
amount equal to that excess. Any impairment charge recognized is limited to the amount of the respective reporting unit's 
allocated goodwill.

Determining the fair value of a reporting unit under the quantitative goodwill impairment test requires judgment and often 
involves the use of significant estimates and assumptions, including an assessment of external factors such as macroeconomic, 
industry, and market conditions, as well as entity-specific factors, such as actual and planned financial performance. These 
estimates and assumptions could have a significant impact on whether or not an impairment charge is recognized and the 
magnitude of any such charge. To assist management in the process of determining any potential goodwill impairment, the 
Company may review and consider appraisals from accredited independent valuation firms. Estimates of fair value are 
primarily determined using discounted cash flows and market comparisons. These approaches involve significant estimates and 
assumptions, including projected future cash flows (including timing), discount rates reflecting the risks inherent in those future 
cash flows, perpetual growth rates, and selection of appropriate market comparable metrics and transactions.

As of the most recent goodwill impairment test performed on October 1, 2020, the Company elected to perform a 

qualitative goodwill impairment test for its Workers' Compensation Insurance and Segregated Portfolio Cell Reinsurance 

141

ProAssurance Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2020

reporting units. These reporting units have historically had an excess of fair value over book value and based on current 
operations are expected to continue to do so; therefore, the Company's annual impairment test for these reporting units was 
performed qualitatively. In applying the qualitative approach, management considered macroeconomic factors, industry and 
market conditions, cost factors that could have a negative impact on the reporting units, actual financial performance of the 
reporting units versus expectations and management's future business expectations. As a result of the qualitative assessments, 
management concluded that it was not more likely than not that the fair value of each of the Company's two reporting units that 
have net goodwill was less than the carrying value of each reporting unit as of the testing date; therefore, no further impairment 
testing was required. No goodwill impairment was recorded during the years ended December 31, 2019 or 2018.

Given the evolving, uncertain nature of the COVID-19 pandemic, the estimates and assumptions used by management in 
these impairment tests have inherent uncertainties, and different assumptions could lead to materially different results including 
impairment charges in the future. Management expects to continue to monitor developments and perform updated analyses as 
necessary. See Note 6 of the Notes to Consolidated Financial Statements for additional information about the Company's 
goodwill.

Other Liabilities

SPC dividends payable represents the undistributed equity contractually payable to the external cell participants of SPCs 

operated by ProAssurance's Cayman Islands subsidiaries, Inova Re and Eastern Re.

Unpaid dividends represent common stock dividends declared by ProAssurance's Board that had not yet been paid. 

Unpaid dividends at December 31, 2019 included a special dividend declared in the fourth quarter of 2018 that was paid in 
January 2020. 

Treasury Shares

Treasury shares are reported at cost and are reflected on the Consolidated Balance Sheets as an unallocated reduction of 

total equity.

Share-Based Payments

Compensation cost for share-based payments is measured based on the grant-date fair value of the award, recognized over 

the period in which the employee is required to provide service in exchange for the award. 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 operating cash inflows.

Subsequent Events

ProAssurance evaluates events that occurred subsequent to December 31, 2020 for recognition or disclosure in its 

Consolidated Financial Statements.

Accounting Changes Adopted

Improvements to Financial Instruments - Credit Losses (ASU 2016-13)

Effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, the FASB 

issued guidance that replaces the incurred loss impairment methodology, which delays recognition of credit losses until a 
probable loss has been incurred, with a methodology that reflects expected credit losses and requires consideration of a broader 
range of reasonable and supportable information to inform credit loss estimates. Included in the scope of this guidance are the 
Company's available-for-sale fixed maturity securities and its financial assets held at amortized cost. Under the new guidance, 
credit losses are required to be recorded through an allowance for expected credit losses account and the income statement will 

142

ProAssurance Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2020

reflect the initial recognition of lifetime expected credit losses for any newly recognized financial assets as well as increases or 
decreases of expected credit losses that have taken place during the period. Credit losses on available-for-sale fixed maturity 
securities are required to be presented as an allowance, rather than as a write-down of the asset, limited to the amount by which 
the fair value is below amortized cost. ProAssurance adopted this guidance beginning January 1, 2020 using a modified 
retrospective application for the portion of the new guidance that relates to its premiums and reinsurance receivables and a 
prospective application for the portion of the new guidance that relates to its available-for-sale fixed maturity securities. 
ProAssurance recorded a cumulative-effect adjustment of $4.1 million, net of related tax impacts, to beginning retained 
earnings as of January 1, 2020 to increase its consolidated allowance for expected credit losses related to its premiums 
receivable. ProAssurance determined that estimated expected credit losses associated with the Company's other financial assets 
held at amortized cost included in the scope of this new guidance was nominal as of January 1, 2020. Adoption of this guidance 
had no material effect on ProAssurance's results of operations, financial position or cash flows.

Simplifying the Test for Goodwill Impairment (ASU 2017-04)

Effective for the fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, the FASB 

issued guidance that simplifies the requirements to test goodwill for impairment for business entities that have goodwill 
reported in their financial statements. The guidance eliminates the second step of the impairment test which measures a 
goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount or the 
reporting unit, with the impairment loss not to exceed the carrying amount of goodwill. This new guidance is expected to 
reduce the complexity and cost of future tests of goodwill for impairment. In addition, the guidance also eliminates the 
requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. ProAssurance 
adopted the guidance beginning January 1, 2020. 

Adoption of this guidance did not have a significant impact on the Company's interim quantitative goodwill impairment 
tests for the Workers' Compensation Insurance or Specialty P&C reporting units performed during the second quarter of 2020 
or on the interim quantitative goodwill impairment tests for the Workers' Compensation Insurance or Segregated Portfolio Cell 
Reinsurance reporting units performed during the third quarter of 2020 as the fair value of each of these reporting units 
exceeded their carrying amounts (see previous discussion of these interim impairment assessments). Adoption of this guidance 
simplified the Company's interim quantitative goodwill impairment test for the Specialty P&C reporting unit during the third 
quarter of 2020 as the Company measured the impairment loss on this reporting unit by the amount that the carrying amount of 
the reporting unit exceeded its fair value, with the impairment charge not to exceed the carrying amount of goodwill. 

Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13)

Effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, the FASB 
issued guidance that eliminates, modifies and adds certain disclosure requirements related to fair value measurements. The new 
guidance eliminates the requirements to disclose the transfers between Level 1 and Level 2 of the fair value hierarchy, the 
policy for the timing of transfers between levels of the fair value hierarchy and the valuation process for Level 3 fair value 
measurements while it modifies existing disclosure requirements related to measurement uncertainty and the requirement to 
disclose the timing of liquidation of an investee's assets for investments in certain entities that calculate NAV. The new 
guidance also adds requirements to disclose changes in unrealized gains and losses included in OCI for recurring Level 3 fair 
value measurements as well as the range and weighted average used to develop significant unobservable inputs for Level 3 fair 
value measurements. An entity is permitted to early adopt any eliminated or modified disclosure requirements and delay 
adoption of the additional disclosure requirements until the guidance is effective. During the third quarter of 2018, 
ProAssurance elected to early adopt the provisions that eliminate and modify certain disclosure requirements within Note 2 on a 
retrospective basis, and adopted the additional disclosure requirements beginning January 1, 2020. Adoption of this guidance 
had no material effect on ProAssurance’s results of operations, financial position or cash flows as it affected disclosures only.

Intangibles - Goodwill and Other-Internal-Use Software (ASU 2018-15)

Effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, the FASB 
amended the new standard regarding accounting for implementation costs in cloud computing arrangements. The amended 
guidance substantially aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a 
service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. 
ProAssurance adopted the guidance beginning January 1, 2020, and adoption had no material effect on ProAssurance’s results 
of operations, financial position or cash flows.

Targeted Improvements to Related Party Guidance for VIEs (ASU 2018-17)

Effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, the FASB 

amended guidance which improves the consistency of the application of the VIE guidance for common control arrangements. 
The amended guidance requires an entity to consider indirect interests held through related parties under common control on a 
143

ProAssurance Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2020

proportional basis rather than as the equivalent of a direct interest in its entirety when determining whether a decision-making 
fee is a variable interest. ProAssurance adopted the guidance beginning January 1, 2020. ProAssurance does not have any 
material indirect interests held through related parties under common control; therefore, adoption had no material effect on 
ProAssurance’s results of operations, financial position or cash flows.

Collaborative Arrangements (ASU 2018-18)

Effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, the FASB 

issued new guidance which clarifies how to assess whether certain transactions between participants in a collaborative 
arrangement should be accounted for under the revenue from contracts with customers accounting standard when the 
counterpart is a customer. In addition, the guidance precludes an entity from presenting consideration from a transaction in a 
collaborative arrangement as revenue from contracts with customers if the counterparty is not a customer for that transaction. 
ProAssurance adopted the guidance beginning January 1, 2020, and adoption had no material effect on ProAssurance’s results 
of operations, financial position or cash flows.

Reference Rate Reform (ASU 2020-04)

The FASB issued guidance intended to assist stakeholders during the market-wide reference rate transition period and is 

effective for a limited period between March 12, 2020 and December 31, 2022. The guidance provides optional expedients and 
exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference LIBOR or another 
reference rate that is expected to be discontinued because of reference rate reform. ProAssurance has exposure to LIBOR-based 
financial instruments through its variable rate Mortgage Loans and Revolving Credit Agreement; however, these agreements 
include provisions for an alternative benchmark rate if LIBOR ceases to exist, which do not materially change the liability 
exposure. Additionally, ProAssurance has exposure to LIBOR in its available-for-sale fixed maturities portfolio which 
represented approximately 6% of total investments, or $191 million as of December 31, 2020; 34% of these investments with 
exposure to LIBOR were issued since 2019 and include provisions for an alternative benchmark rate. Optional expedients for 
contract modifications include a prospective adjustment that does not require contract remeasurement or reassessment of a 
previous accounting determination; therefore, the modified contract is accounted for as a continuation of the existing contract. 
ProAssurance adopted the guidance beginning March 12, 2020, and adoption had no material effect on ProAssurance's results 
of operations, financial position or cash flows.

Simplifying the Accounting for Income Taxes (ASU 2019-12)

Effective for fiscal years beginning after December 15, 2020 and interim periods within those fiscal years, the FASB 

issued new guidance which is intended to simplify various aspects related to accounting for income taxes. In addition, it 
removes certain exceptions to the general principles in the income tax guidance in the codification and also clarifies and amends 
existing guidance to improve consistent application. ProAssurance elected to early adopt this guidance using a prospective 
application during the second quarter of 2020. The most impactful provision of the new guidance on the Company is the 
removal of the limitation on the tax benefit recognized on pre-tax losses during interim periods in which the year-to-date loss 
exceeds the expected loss for the fiscal year.

Accounting Changes Not Yet Adopted

Clarifying the Interactions between Investments - Equity Securities, Investments - Equity Method and Joint Ventures, and 
Derivatives and Hedging (ASU 2020-01)

Effective for fiscal years beginning after December 15, 2020 and interim periods within those fiscal years, the FASB 

amended guidance that clarifies the accounting for the transition into and out of the equity method and measuring certain 
purchased options and forward contracts to acquire investments. ProAssurance plans to adopt the guidance beginning January 1, 
2021, and adoption is not expected to have a material effect on ProAssurance's results of operations, financial position or cash 
flows.

2. 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:

Level 2:

Level 3:

quoted (unadjusted) market prices in active markets for identical assets and liabilities. For ProAssurance, 
Level 1 inputs are generally quotes for securities actively traded in exchange or over-the-counter 
markets.

market data obtained from sources independent of the reporting entity (observable inputs). For 
ProAssurance, Level 2 inputs generally include quoted prices in markets that are not active, quoted 
prices for similar assets or liabilities, and results from pricing models that use observable inputs such as 
interest rates and yield curves that are generally available at commonly quoted intervals.

the reporting entity’s own assumptions about market participant assumptions based on the best 
information available in the circumstances (non-observable inputs). For ProAssurance, Level 3 inputs 
are used in situations where little or no Level 1 or 2 inputs are available or are inappropriate given the 
particular circumstances. Level 3 inputs include results from pricing models for which some or all of the 
inputs are not observable, discounted cash flow methodologies, single non-binding broker quotes and 
adjustments to externally quoted prices that are based on management judgment or estimation.

Fair values of assets measured at fair value on a recurring basis as of December 31, 2020 and December 31, 2019 are 
shown in the following tables. Where applicable, the tables also indicate the fair value hierarchy of the valuation techniques 
utilized to determine those fair values. For some assets, the inputs used to measure fair value may fall into different levels of the 
fair value hierarchy. When this is the case, the asset is categorized based on the level of the most significant input to the fair 
value measurement. Assessments of the significance of a particular input to the fair value measurement require judgment and 
consideration of factors specific to the assets being valued.

Total assets at fair value

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

by one of several third party, nationally recognized pricing services, including services that price only certain types of 
securities. Each service uses complex methodologies to determine values for securities and subject the values they develop to 
quality control reviews. Management selected a primary source for each type of security in the portfolio and reviewed the 
values provided for reasonableness by comparing data to alternate pricing services and to available market and trade data. 
Values that appeared inconsistent were further reviewed for appropriateness. Any value that did not appear reasonable was 
discussed with the service that provided the value and adjusted, if necessary. There were no material changes to the values 
supplied by the pricing services during the years ended December 31, 2020 and 2019.

Level 2 Valuations

Below is a summary description of the valuation methodologies primarily used by the pricing services for securities in the 

Level 2 category, by security type:

U.S. Treasury obligations were valued based on quoted prices for identical assets, or, in markets that are not active, quotes 

for similar assets, taking into consideration adjustments for variations in contractual cash flows and yields to maturity.

U.S. Government-sponsored enterprise obligations were 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 
were included in the valuation process when necessary to reflect recent regulatory, government or corporate actions or 
significant economic, industry or geographic events affecting the security’s fair value.

State and municipal bonds were valued using a series of matrices that considered credit ratings, the structure of the 
security, the sector in which the security falls, yields and contractual cash flows. Valuations were further adjusted, when 
necessary, to reflect the expected effect on fair value of recent significant economic or geographic events or ratings changes.

Corporate debt, multiple observable inputs consisted primarily of corporate bonds, but also included a small number of 

bank loans. The methodology used to value Level 2 corporate bonds was the same as the methodology previously described for 
U.S. Government-sponsored enterprise obligations. Bank loans were valued based on an average of broker quotes for the loans 
in question, if available. If quotes were not available, the loans were valued based on quoted prices for comparable loans or, if 
the loan was newly issued, by comparison to similar seasoned issues. Broker quotes were compared to actual trade prices to 
permit assessment of the reliability of the quotes; unreliable quotes were not considered in quoted averages.

Residential and commercial mortgage-backed securities were valued using a pricing matrix which considers the issuer 

type, coupon rate and longest cash flows outstanding. The matrix used was based on the most recently available market 
information. Agency and non-agency collateralized mortgage obligations were 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.

Other asset-backed securities were 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.

Fixed maturities, trading, are held by the Lloyd's Syndicates segment and include U.S. Treasury obligations, corporate 

debt with multiple observable inputs and other asset-backed securities. These securities were valued using the respective 
valuation methodologies discussed above for each security type.

Short-term investments were securities maturing within one year, carried at fair value which approximated the cost of the 

securities due to their short-term nature.

Other investments consisted primarily of convertible bonds valued using a pricing model that incorporated selected dealer 

quotes as well as current market data regarding equity prices and risk free rates. If dealer quotes were unavailable for the 
security being valued, quotes for securities with similar terms and credit status were used in the pricing model. Dealer quotes 
selected for use were those considered most accurate based on parameters such as underwriter status and historical reliability.

Other assets consisted of an interest rate cap derivative instrument valued using a model which considers the volatilities 

from other instruments with similar maturities, strike prices, durations and forward yield curves. Under the terms of the interest 
rate cap agreement, ProAssurance paid a premium of $2 million for the right to receive cash payments based upon a notional 
amount of $35 million if and when the three-month LIBOR rises above 2.35%. The Company's variable-rate Mortgage Loans 
bear an interest rate of three-month LIBOR plus 1.325%.

Level 3 Valuations

Below is a summary description of the valuation methodologies used as well as quantitative information regarding 

securities in the Level 3 category, by security type:

Level 3 Valuation Methodologies

Corporate debt, limited observable inputs consisted of corporate bonds valued using dealer quotes for similar securities or 
discounted cash flow models using yields currently available for similar securities. Similar securities are defined as securities of 
comparable credit quality that have like terms and payment features. Assessments of credit quality were based on NRSRO 
ratings, if available, or were determined by management if not available. At December 31, 2020, 100% of the securities were

Notes to Consolidated Financial Statements

rated and the average rating was BB+. At December 31, 2019, 66% of the securities were rated and the average rating was 
BBB-.

Residential mortgage-backed and other asset-backed securities consisted of securitizations of receivables valued using 

dealer quotes for similar securities or discounted cash flow models using yields currently available for similar securities. 
Similar securities are defined as securities of comparable credit quality that have like terms and payment features. Assessments 
of credit quality were based on NRSRO ratings, if available, or were subjectively determined by management if not available. 
At December 31, 2020, 51% of the securities were rated and the average rating was AA-. At December 31, 2019, 100% of the 
securities were rated and the average rating was AA.

Other investments consisted of convertible securities for which limited observable inputs were available at December 31, 

2019. The securities were valued internally based on expected cash flows, including the expected final recovery, discounted at a 
yield that considered the lack of liquidity and the financial status of the issuer.

Fair Values Not Categorized

At December 31, 2020 and 2019, certain LPs/LLCs and investment funds measure fund assets at fair value on a recurring 

basis and provide a NAV for ProAssurance's interest. The carrying value of these interests is based on the NAV provided and 
was considered to approximate the fair value of the interests. For investment in unconsolidated subsidiaries, ProAssurance 
recognizes any changes in the NAV of its interests in equity in earnings (loss) of unconsolidated subsidiaries during the period 
of change. In accordance with GAAP, the fair value of these investments was not classified within the fair value hierarchy. The

Below is additional information regarding each of the investments listed in the table above as of December 31, 2020.

(1) This investment fund is focused on the structured mortgage market. The fund primarily invests in U.S. Agency
mortgage-backed securities. Redemptions are allowed at the end of any calendar quarter with a prior notice
requirement of 65 days and are paid within 45 days at the end of the redemption dealing day.

(2) This investment is comprised of interests in two unrelated LP funds that are structured to provide interest

distributions primarily through diversified portfolios of private debt instruments. One LP allows redemption by
special consent, while the other does not permit redemption. Income and capital are to be periodically distributed at
the discretion of the LPs over an anticipated time frame that spans from three to eight years.

(3) This fund is a LP that holds long equities of public international companies and was fully redeemed during the second

quarter of 2020.

(4) This investment holds primarily long and short North American equities and targets absolute returns using strategies

designed to take advantage of market opportunities. Redemptions are permitted; however, redemptions above
specified thresholds (lowest threshold is 90%) may be only partially payable until after a fund audit is completed and
are then payable within 30 days.

(5) This investment is comprised of interests in multiple unrelated LP funds, each structured to provide capital

appreciation through diversified investments in private equity, which can include investments in buyout, venture
capital, debt including senior, second lien and mezzanine, distressed debt, collateralized loan obligations and other
private equity-oriented LPs. Two of the LPs allow redemption by terms set forth in the LP agreements; the others do
not permit redemption. Income and capital are to be periodically distributed at the discretion of the LP over time
frames that are anticipated to span up to ten years.

(6) This fund is a LLC structured to build and manage low volatility, multi-manager portfolios that have little or no
correlation to the broader fixed income and equity security markets. Redemptions are not permitted but offers to
repurchase units of the LLC may be extended periodically. This fund was fully redeemed during the fourth quarter of
2020.

151

ProAssurance Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2020

(7) This investment is comprised of four unrelated LP funds. Two funds seek to obtain superior risk-adjusted absolute

returns through a diversified portfolio of debt securities, including bonds, loans and other asset-backed instruments. A
third fund focuses on private middle market company mezzanine loans, while the remaining fund seeks event driven
opportunities across the corporate credit spectrum. Two funds are allowed redemptions at any quarter-end with a
prior notice requirement of 90 days; one fund permits redemption at any quarter-end with a prior notice requirement
of 180 days and one fund does not allow redemptions. For the fund that does not allow redemptions, income and
capital are to be periodically distributed at the discretion of the LP over time frames that are anticipated to span up to
twelve years.

(8) This fund is a LLC invested across a broad range of commodities and focuses primarily on market neutral, relative
value strategies, seeking to generate absolute returns with low correlation to broad commodity, equity and fixed
income markets. This fund was fully redeemed during the second quarter of 2020.

(9) This investment is comprised of multiple unrelated LPs/LLCs funds. One fund is a LLC focused on investing in
North American consumer products companies, comprised of equity and equity-related securities, as well as debt
instruments. A second fund is focused on aircraft investments, along with components and assets related to aircrafts.
For both funds, redemptions are not permitted. Another fund is a LP focused on North American energy
infrastructure assets that allows redemption with consent of the General Partner. The remaining funds are real estate
focused LPs, one of which allows for redemption with prior notice.

ProAssurance may not sell, transfer or assign its interest in any of the above LPs/LLCs without special consent from the 

LPs/LLCs.

Nonrecurring Fair Value Measurement

During the third quarter of 2020, ProAssurance recognized a nonrecurring fair value measurement related to the goodwill 

in its Specialty P&C reporting unit with a carrying value of $161.1 million prior to the fair value measurement. This 
nonrecurring fair value measurement resulted in the goodwill being written down to its implied fair value of zero resulting in an 
impairment of the goodwill of $161.1 million. The inputs used in the fair value measurement were non-observable and, as such, 
were categorized as a Level 3 valuation. ProAssurance did not have any other assets or liabilities that were measured at fair 
value on a nonrecurring basis at December 31, 2020 or 2019.

* Carrying value excludes unamortized debt issuance costs.

The fair value of the BOLI was equal to the cash surrender value associated with the policies on the valuation date.

Other investments listed in the table above include FHLB common stock carried at cost and an annuity investment carried

at amortized cost. Two of ProAssurance's insurance subsidiaries are members of an FHLB. The estimated fair value of the 
FHLB common stock was based on the amount the subsidiaries would receive if their memberships were canceled, as the 
memberships cannot be sold. The fair value of the annuity represents the present value of the expected future cash flows 
discounted using a rate available in active markets for similarly structured instruments.

Other assets and other liabilities primarily consisted of related investment assets and liabilities associated with funded 

deferred compensation agreements. The fair value of the funded deferred compensation assets was based upon quoted market 
prices, which is categorized as a Level 1 valuation, and had a fair value of $30.6 million and $26.9 million at December 31, 
2020 and 2019, respectively. The deferred compensation liabilities are adjusted to match the fair value of the deferred 
compensation assets. Other assets also included an unsecured note receivable under a separate line of credit agreement. The fair 
value of the note receivable was based on the present value of expected cash flows from the note receivable, discounted at 
market rates on the valuation date for receivables with similar credit standings and similar payment structures.

The fair value of the debt was estimated based on the present value of expected future cash outflows, discounted at rates 

available on the valuation date for similar debt issued by entities with a similar credit standing to ProAssurance.

Excluding obligations of the U.S. Government, U.S. Government-sponsored enterprises and a U.S. Government 

obligations money market fund, no investment in any entity or its affiliates exceeded 10% of shareholders’ equity at 
December 31, 2020.

Cash and securities with a carrying value of $42.3 million at December 31, 2020 were on deposit with various state 

insurance departments to meet regulatory requirements.

As a member of Lloyd's, ProAssurance is required to maintain capital at Lloyd's, referred to as FAL, to support 

underwriting by Syndicate 1729 and Syndicate 6131. At December 31, 2020, ProAssurance's FAL investments were comprised 
of available-for-sale fixed maturities with a fair value of $95.0 million and cash and cash equivalents of $11.2 million on 
deposit with Lloyd's in order to satisfy these FAL requirements. During the third quarter of 2020, ProAssurance received a 
return of approximately $32.3 million of cash and cash equivalents from its FAL balances given the Company's reduced 
participation in the results of Syndicate 1729 for the 2020 underwriting year to 29% from 61%.

As of December 31, 2020, excluding U.S. Government or U.S. Government-sponsored enterprise obligations, there were 

292 debt securities (11.1% of all available-for-sale fixed maturity securities held) in an unrealized loss position representing 
229 issuers. The greatest and second greatest unrealized loss positions among those securities were approximately $0.4 million 
and $0.2 million, respectively. The securities were evaluated for impairment as of December 31, 2020.

As of December 31, 2019, excluding U.S. Government or U.S. Government-sponsored enterprise obligations, there were 

263 debt securities (12.1% of all available-for-sale fixed maturity securities held) in an unrealized loss position representing 
204 issuers. The greatest and second greatest unrealized loss positions among those securities were approximately $0.2 million 
and $0.1 million, respectively. The securities were evaluated for impairment as of December 31, 2019.

Each quarter, ProAssurance performs a detailed analysis for the purpose of assessing whether any of the securities it holds 
in an unrealized loss position has suffered an impairment due to credit or non-credit factors. A detailed discussion of the factors 
considered in the assessment is included in Note 1.

Fixed maturity securities held in an unrealized loss position at December 31, 2020, 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, excluding those issued by GNMA, FNMA and FHLMC, held in an unrealized loss position were estimated as part of

Balance Sheets as of December 31, 2020 and 2019 primarily included stocks, bond funds and investment funds.

Short-term Investments

ProAssurance's short-term investments, which have a maturity at purchase of one year or less, are primarily comprised of 
investments in U.S. treasury obligations, commercial paper and money market funds. Short-term investments are carried at fair 
value which approximates the cost of the securities due to their short-term nature.

BOLI

ProAssurance holds BOLI policies that are carried at the current cash surrender value of the policies (original cost $33 

million). All insured individuals were members of ProAssurance management at the time the policies were acquired. The 
primary purpose of the program is to offset future employee benefit expenses through earnings on the cash value of the policies.

Qualified affordable housing project tax credit partnership interests held by ProAssurance generate investment returns by 

providing tax benefits to fund investors in the form of tax credits and project operating losses. The carrying value of these 
investments reflects ProAssurance's total commitments (both funded and unfunded) to the partnerships, less any amortization. 
ProAssurance's ownership percentage relative to two of the tax credit partnership interests is almost 100%; these interests had a 
carrying value of $9.4 million and $17.2 million at December 31, 2020 and 2019, respectively. ProAssurance's ownership 
percentage relative to the remaining tax credit partnership interests is less than 20%; these interests had a carrying value of 
$18.3 million and $29.2 million at December 31, 2020 and 2019, respectively. Since ProAssurance has the ability to exert 
influence over the partnerships but does not control them, all are accounted for using the equity method. See further discussion 
of the entities in which ProAssurance holds passive interests in Note 14.

ProAssurance's other tax credit partnership is an investment in a historic tax credit partnership that generates investment 

returns by providing benefits to fund investors in the form of tax credits, tax deductible project operating losses and positive 
cash flows. The carrying value of this investment reflects ProAssurance's total funded commitment less any amortization. 
During the second quarter of 2020, this investment was fully amortized up to the total current funded commitment.  
ProAssurance's ownership percentage relative to the historic tax credit partnership is almost 100%. Since ProAssurance has the 
ability to exert influence over the partnership but does not control it, it is accounted for using the equity method. See further 
discussion of the entities in which ProAssurance holds passive interests in Note 14.

ProAssurance holds interests in investment fund LPs/LLCs and other equity method investments and LPs/LLCs which are 

not considered to be investment funds. ProAssurance's ownership percentage relative to four of the LPs/LLCs is greater than 
25%, which is expected to be reduced as the funds mature and other investors participate in the funds; these investments had a 
carrying value of $46.2 million at December 31, 2020 and $41.0 million at December 31, 2019. ProAssurance's ownership 
percentage relative to the remaining investments and LPs/LLCs is less than 25%; these interests had a carrying value of $236.6 
million at December 31, 2020 and $269.3 million at December 31, 2019. ProAssurance does not have the ability to exert control 
over any of these funds.

For the year ended December 31, 2020, ProAssurance recognized $1.5 million of credit-related impairment losses in 
earnings and a nominal amount of non-credit impairment losses in OCI. The credit-related impairment losses recognized in 
2020 primarily related to corporate bonds in the energy and consumer sectors. Additionally, 2020 included credit-related 
impairment losses related to four corporate bonds in various sectors, which were sold during 2020. The non-credit impairment 
losses recognized during 2020 related to three corporate bonds in the energy and consumer sectors. For the year ended 
December 31, 2019, ProAssurance recognized credit-related impairment losses in earnings of $0.8 million and nominal amount 
of non-credit impairment losses in OCI, both of which related to three corporate bonds in the energy and consumer sectors. For

ProAssurance Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2020

the year ended December 31, 2018, ProAssurance recognized credit-related impairment losses in earnings of $0.5 million 
related to debt instruments from two issuers in the energy sector.

ProAssurance recognized $15.7 million of net realized investment gains during 2020, driven primarily by realized gains 
on the sale of available-for-sale fixed maturities and equity investments, partially offset by unrealized holding losses resulting 
from decreases in the fair value on the Company's equity portfolio due to the volatility in the global financial markets related to 
COVID-19. ProAssurance recognized $59.9 million of net realized investment gains during 2019 driven by both realized gains 
from the sale of equity investments and unrealized holding gains on the Company's equity portfolio due to the improvement in 
the market since December 31, 2018, which caused the Company's equity securities to increase in value. The most significant 
sectors that benefited from the improvement in the market were the financial and energy sectors. ProAssurance recognized 
$43.5 million of net realized investment losses during 2018 driven by unrealized holding losses on the Company's equity 
portfolio due to market volatility throughout 2018, which caused the securities to decline in value; the most significant sectors 
impacted were the financial and energy sectors, although all sectors were impacted.

exposure to losses, to provide capacity to write larger limits of liability, to provide reimbursement for losses incurred under the 
higher limit coverages the Company offers and as a mechanism for providing custom insurance solutions. ProAssurance also

The receivable from reinsurers on unpaid losses and LAE represents management’s estimated amount of future loss 

payments that will be recoverable under ProAssurance reinsurance agreements. Certain of the Company's reinsurance 
agreements base the amount of premium that is due to the reinsurer in part on losses reimbursed or to be reimbursed under the 
agreement, and terms may also include minimum and maximum amounts of ceded premium. Ceded premium amounts are 
estimated based on management’s expectation of ultimate losses and the portion of those losses that are allocable to reinsurers 
according to the terms of the agreements, including any minimums or maximums. Given the uncertainty of the ultimate 
amounts of losses, management’s estimates of losses and related amounts recoverable may vary significantly from the eventual 
outcome. Due to changes in management’s estimates of amounts due to reinsurers related to prior accident year loss recoveries, 
ProAssurance increased premiums ceded in its Specialty P&C segment by $0.7 million, $2.8 million and $5.5 million during 
the years ended December 31, 2020, 2019 and 2018, respectively. 

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. ProAssurance continually monitors its 
reinsurers to minimize its exposure to significant losses from reinsurer insolvencies.

At December 31, 2020, the net total amounts due from reinsurers was $395.3 million (receivables related to paid and 
unpaid losses and LAE and prepaid reinsurance premiums, less reinsurance premiums payable). No single reinsurer had an 
individual balance which exceeded $51.0 million.

At December 31, 2020 reinsurance recoverables totaling approximately $96.1 million were collateralized by letters of 
credit or funds withheld. Expected credit losses associated with the Company's reinsurance receivables (related to both paid and 
unpaid losses) were nominal in amount as of December 31, 2020. ProAssurance had no allowance for expected credit losses 
related to our reinsurance receivables at December 31, 2019 or 2018. During the years ended December 31, 2020, 2019 or 
2018, no reinsurance balances were written off for credit reasons. For further information on our allowance for expected credit 
losses related to our receivables from reinsurers see Note 1.

During the fourth quarter of 2020, ProAssurance commuted a quota share reinsurance agreement with one of its reinsurers 

which resulted in a net cash receipt of approximately $6.8 million and reduced its receivable from reinsurers on unpaid losses 
and LAE by approximately $7.0 million. 

During the fourth quarter of 2018 and 2017, ProAssurance commuted the 2017 and 2016 calendar year quota share 
reinsurance arrangements, respectively, between the Specialty P&C segment and Syndicate 1729. Due to the quarter lag, the 
effects of the 2017 and 2016 commutations were reported in both the Specialty P&C and Lloyd's Syndicates segments results 
during the first quarter of 2019 and 2018, respectively, which resulted in a net cash receipt of approximately $3.1 million and 
$6.1 million, respectively. The commutations reduced the receivable from reinsurers on unpaid losses and LAE, combined, by 
approximately $3.8 million and $6.7 million during the years ended December 31, 2019 and 2018, respectively.

As of December 31, 2020, ProAssurance had U.S. state and U.K. income tax NOL carryforwards of approximately 
$52.7 million and $32.9 million, respectively. The U.K. NOL carryforwards do not expire while the state NOL carryforwards 
will begin to expire in 2031. 

ProAssurance had $36.1 million of available tax credit carryforwards generated from the Company's investments in tax 

credit partnerships, of which $18.2 million and $17.9 million may be carried forward until December 31, 2039 and 2040, 
respectively. These tax credits have been deferred and carried forward due to the Company's realized NOL in 2019 and 
expected NOL in 2020.

In 2020 and 2019, management evaluated the realizability of the deferred tax asset related to the U.K. NOL carryforwards 

and concluded that it was more likely than not that the deferred tax asset will not be realized; therefore, a valuation allowance 
was recorded against the full value of the deferred tax asset related to the U.K. NOL carryforwards in both 2020 and 2019 of 
$6.2 million and $4.9 million, respectively. The increase in the valuation allowance related to the U.K. NOL carryforward in 
2020 as compared to 2019 was primarily due to an increase in the U.K. tax rate from 17% to the current tax rate of 19% as well 
as current year activity.

In 2020, management evaluated the realizability of the deferred tax asset related to the U.S. state NOL carryforwards and 

concluded that it was more likely than not that a portion of the deferred tax asset will not be realized; therefore, a valuation 
allowance was recorded against a portion of the deferred tax asset related to the U.S. state NOL carryforwards in 2020 of 
$1.9 million.

Deferred tax assets and liabilities include SPCs the Company participates in at Inova Re, net of a valuation allowance of 
$0.5 million and $0.6 million at December 31, 2020 and 2019, respectively. Due to the limited operations of these SPCs as of 
December 31, 2020 and 2019, management concluded that a valuation allowance was required against the DTAs of certain 
SPCs. The nominal decrease in the valuation allowance related to the SPCs at Inova Re is due to current year activity.

ProAssurance files income tax returns in various states, the U.S. federal jurisdiction and the U.K. ProAssurance had a 
receivable for U.S. federal and U.K. income taxes of $18.9 million at December 31, 2020 and $8.0 million at December 31, 
2019, both carried as a part of other assets.

The statute of limitations is now closed for all tax years prior to 2017.

At December 31, 2020 and 2019, approximately $0.8 million and $1.2 million, respectively, of ProAssurance's uncertain 
tax positions, if recognized, would affect the effective tax rate. As with any uncertain tax position, there is a possibility that the 
ultimate benefit realized could differ from the estimate management has established. Management believes that it is reasonably 
possible that a portion of unrecognized tax benefits at December 31, 2020 may change during the next twelve months. 
However, an estimate of the change cannot be made at this time.

ProAssurance recognizes interest and/or penalties related to income tax matters as a component of income tax expense. 

Interest and penalties recognized in the Consolidated Statements of Income and Comprehensive Income was nominal for each 
of the years ended December 31, 2020, 2019 and 2018. The accrued liability for interest was approximately $0.5 million and 
$0.6 million at December 31, 2020 and 2019, respectively.

The Company's pre-tax loss in 2020 included a $161.1 million goodwill impairment recognized in relation to the Specialty 

P&C reporting unit during the third quarter of 2020. Of the $161.1 million goodwill impairment, $149.6 million was non-
deductible for which no tax benefit was recognized while the remaining $11.5 million was deductible for which a 21% tax 
benefit was recognized on the related tax amortization. See further discussion on this goodwill impairment in Notes 1 and 6. 
The tax rate differential on loss carryback for the year ended December 31, 2020 represents the additional tax rate differential of 
14% on the carryback of the 2020 and 2019 NOLs to the 2015 and 2014 tax years, respectively, as a result of changes made by 
the CARES Act to the NOL provisions of the tax law (see further discussion in this section under the heading "Coronavirus 
Aid, Relief and Economic Security Act"). 

Tax Cuts and Jobs Act

The TCJA introduced a minimum tax on payments made to related foreign entities referred to as the BEAT. The BEAT is 

imposed by adding back into the U.S. tax base any base erosion payment made by the U.S. taxpayer to a related foreign entity 
and applying a minimum tax rate to this newly calculated modified taxable income. Base erosion payments represent any 
amount paid or accrued by the U.S. taxpayer to a related foreign entity for which a deduction is allowed. Premiums the 
Company cedes to the SPCs at Inova Re, one of its other wholly owned Cayman Islands reinsurance subsidiaries, do not fall 
within the scope of base erosion payments as the SPCs at Inova Re have elected to be taxed as U.S. taxpayers. However, 
premiums the Company cedes to any active SPC at its wholly owned Cayman Islands reinsurance subsidiary, Eastern Re, fall 
within the scope of base erosion payments and therefore could be significantly impacted by the BEAT. See further discussion 
on the Company’s Cayman Islands SPC operations in Note 16. Management has evaluated its exposure to the BEAT and has 
concluded that the Company’s expected outbound deductible payments to related foreign entities are below the threshold for 
application of the BEAT; therefore, ProAssurance has not recognized any incremental tax expense for the BEAT provision of 
the TCJA during the years ended December 31, 2020 or 2019.

The TCJA also requires a U.S. shareholder of a controlled foreign corporation to include its GILTI in U.S. taxable 
income. The GILTI amount is based on the U.S. shareholder’s aggregate share of the gross income of the controlled foreign 
corporation reduced by certain exceptions and a net deemed tangible income return. The net deemed tangible income return is 
based on the controlled foreign corporation’s basis in the tangible depreciable business property. Cell rental fee income earned 
by Inova Re and Eastern Re fall within the scope of the GILTI provisions of the TCJA. Management has evaluated the new 
GILTI provisions of the TCJA, and has made an accounting policy election to treat the taxes due on the inclusion of GILTI in 
U.S. taxable income as a current period expense when incurred. ProAssurance recognized a nominal amount of tax expense for 
the GILTI provision of the TCJA during each of the years ended December 31, 2020 and 2019.

Coronavirus Aid, Relief and Economic Security Act

In response to COVID-19, the CARES Act was signed into law on March 27, 2020 and contains several provisions for 
corporations and eases certain deduction limitations originally imposed by the TCJA. The CARES Act, among other things, 
includes temporary changes regarding the prior and future utilization of NOLs, temporary changes to the prior and future 
limitations on interest deductions, temporary suspension of certain payment requirements for the employer portion of Social 
Security taxes and the creation of certain refundable employee retention credits. ProAssurance has an NOL of approximately 
$45.3 million from the 2020 tax year that will be carried back to the 2015 tax year and is expected to generate a tax refund of 
approximately $15.9 million. Additionally, ProAssurance had an NOL of approximately $25.6 million from the 2019 tax year 
which was carried back to the 2014 tax year and generated a tax refund of approximately $9.0 million which we received in 
February 2021. ProAssurance has evaluated the other provisions of the CARES Act and has concluded that they will not have a 
material impact on the Company's financial position or results of operations.

6. Goodwill

Goodwill is recognized in conjunction with business acquisitions as the excess of the purchase consideration for the 

business acquisition over the fair value of identifiable assets acquired and liabilities assumed. The fair value of identifiable 
assets and liabilities, and thus goodwill, is subject to redetermination within a measurement period of up to one year following 
completion of a business acquisition.

Goodwill is tested for impairment annually or more frequently if circumstances indicate an impairment may have 
occurred. The date of the Company's annual goodwill impairment test is October 1. Impairment of goodwill is tested at the 
reporting unit level, which is consistent with the Company's reportable segments identified in Note 16. Of the Company's five 
reporting units, three have goodwill - Specialty P&C, Workers' Compensation Insurance and Segregated Portfolio Cell 
Reinsurance.

As discussed in Note 1, during the third quarter of 2020 the Company recorded a pre-tax impairment charge of $161.1 

million to fully impair the goodwill in the Specialty P&C reporting unit. The Company performed its annual goodwill 
impairment assessment as of October 1, 2020. Management concluded that it was not more likely than not that the fair value of 
each of the Company's two reporting units that have net goodwill was less than the carrying value of each reporting unit as of 
the testing date; therefore, no goodwill impairment was recorded during the fourth quarter of 2020.   

There were no changes in the carrying amount of goodwill or accumulated impairment losses for the year ended 

December 31, 2019. The table below presents the carrying amount of goodwill and accumulated impairment losses by reporting 
unit at December 31, 2020:

7. Deferred Policy Acquisition Costs

Policy acquisition costs that are incremental and directly related to the successful production of new and renewal 
insurance contracts, most significantly agent commissions, premium taxes, and underwriting salaries and benefits, are 
capitalized as policy acquisition costs and amortized to expense, net of ceding commissions earned, as the related premium 
revenues are earned. Amortization of DPAC was $110.6 million, $115.3 million and $104.5 million for the years ended 
December 31, 2020, 2019 and 2018, respectively.

ProAssurance evaluates the recoverability of DPAC typically at the segment level each reporting period, or in a manner 
that is consistent with the way the Company manages its business. Any amounts estimated to be unrecoverable are charged to 
expense in the current period as a component of DPAC amortization in the Consolidated Statement of Income and 
Comprehensive Income.

As part of the evaluation of the recoverability of DPAC, ProAssurance also evaluates its unearned premiums for premium 

deficiencies. A premium deficiency is recognized if the sum of anticipated losses and loss adjustment expenses, unamortized 
DPAC and maintenance costs, net of anticipated investment income, exceeds the related unearned premium. If a premium 
deficiency is identified, the associated DPAC is charged to expense as a component of DPAC amortization in the Consolidated 
Statement of Income and Comprehensive Income, and a PDR is recorded for the excess deficiency as a component of net losses 
and loss adjustment expenses in the Consolidated Statement of Income and Comprehensive Income and as a component of the 
reserve for losses on the Consolidated Balance Sheet. For the years ended December 31, 2020 and 2018, ProAssurance did not 
determine any DPAC to be unrecoverable. For the year ended December 31, 2019, ProAssurance established a $9.2 million 
PDR and a nominal amount of DPAC was charged to expense as it was determined to be unrecoverable. The $9.2 million PDR 
was fully amortized during 2020.

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 the reserve, particularly the reserve appropriate for liability 
exposures, is a complex process. For a high proportion of the risks insured or reinsured by ProAssurance, claims may be 
resolved over an extended period of time, often five years or more, and may be subject to litigation. Estimating losses requires 
ProAssurance to make and revise judgments and assessments regarding multiple uncertainties over an extended period of time. 
As a result, the reserve estimate may vary considerably from the eventual outcome. The assumptions used in establishing 
ProAssurance’s reserve are regularly reviewed and updated by management as new data becomes available. Changes to 
estimates of previously established reserves are included in earnings in the period in which the estimate is changed.

ProAssurance believes that the methods it uses to establish reserves are reasonable and appropriate. Each year, 

ProAssurance uses internal actuaries to review the reserve for losses of each insurance subsidiary. ProAssurance also engages 
consulting actuaries to review ProAssurance claims data and provide observations regarding cost trends, rate adequacy and 
ultimate loss costs. The statutory filings of each insurance company with the insurance regulators must be accompanied by a 
consulting actuary's certification as to their respective reserves. ProAssurance considers the views of the actuaries as well as 
other factors, such as premium rates, historical paid and incurred loss development trends and an evaluation of the current loss 
environment including frequency, severity, the expected effect of inflation, general economic and social trends, and the legal 
and political environment in establishing the amount of its reserve for losses. As of December 31, 2020, the Company expects 
there will be impacts to these factors as well as to the timing of loss emergence and ultimate loss ratios for certain coverages it 
underwrites as a result of COVID-19 and the related economic shutdown; however, the extent to which COVID-19 impacts 
these factors is highly uncertain and cannot be predicted. The industry is experiencing new conditions, including the 
postponement of court cases, changes in settlement trends and a significant reduction in economic activity and insured exposure 
in some classes. ProAssurance's booked reserves as of December 31, 2020 include consideration of these factors, but the 
duration and degree to which these issues persist, along with potential legislative, regulatory or judicial actions, could result in 
significant changes to the Company's reserve estimates in future periods.

ProAssurance partitions its reserve by accident year, which is the year in which the claim becomes its liability. For claims-

made policies, the insured event generally becomes a liability when the event is first reported to the Company. For occurrence 
policies, the insured event becomes a liability when the event takes place. For retroactive coverages, the insured event becomes 
a liability at inception of the underlying contract. As claims are incurred (reported) and claim payments are made, they are 
aggregated by accident year for analysis purposes. ProAssurance also partitions its reserve by reserve type: case reserves and 
IBNR reserves. Case reserves are established by the claims department based upon the particular circumstances of each 
reported claim and represent ProAssurance’s 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 

166

ProAssurance Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2020

downward as estimates regarding the amount of future losses are revised; a reported loss for an individual claim equates to the 
case reserve at any point in time plus the claim payments that have been made to date. IBNR reserves represent an estimate, in 
the aggregate, of future development on losses that have been reported to ProAssurance plus an estimate of losses that have 
been incurred but not reported.

Development of Prior Accident Years

In addition to setting the initial reserve for the current accident year, each period ProAssurance reassesses the amount of 

reserve required for prior accident years. The foundation of ProAssurance’s reserve re-estimation process is an actuarial 
analysis that is performed by both the internal and consulting actuaries. This detailed analysis projects ultimate losses based on 
partitions which include line of business, geography, coverage layer and accident year. The procedure uses the most 
representative data for each partition, capturing its unique patterns of development and trends. ProAssurance believes that the 
use of consulting actuaries provides an independent view of the loss data as well as a broader perspective on industry loss 
trends.

Reserving Methodologies

For the HCPL, Medical Technology Liability and Workers’ Compensation lines of business, the analysis performed by 
the consulting actuaries analyzes each partition of the business in a variety of ways and uses multiple actuarial methodologies in 
performing these analyses, including: Bornhuetter-Ferguson (Paid and Reported) Method, Paid Development Method, Reported 
(Incurred) Development Method, Average Paid Value Method and Average Reported Value Method. Generally, methods such 
as the Bornhuetter-Ferguson Method are used on more recent accident years where there is less data available on which to base 
the analysis. As time progresses and an increased amount of data is available for a given accident year, management gives more 
confidence to the development and average methods, as these methods typically rely more heavily on ProAssurance's own 
historical data. These methods emphasize different aspects of loss reserve estimation and provide a variety of perspectives for 
ProAssurance's decisions.

For the Workers’ Compensation line of business in both the Workers' Compensation Insurance and Segregated Portfolio 

Cell Reinsurance segments, ProAssurance utilizes the Reported (Incurred) Development Method, Paid Loss Development 
Method and Bornhuetter-Ferguson Method, to develop the reserve for each accident year. The actuarial review includes the 
stratification of claims data (lost time claims and medical only claims) using different variations that allow for identification of 
trends that may not be readily identifiable if the data was evaluated only in the aggregate. Reported and paid loss development 
factors are key assumptions in the reserve estimation process and are based on ProAssurance’s historical reported and paid loss 
development patterns. As accident years mature, the various actuarial methodologies produce more consistent loss estimates.

For the Lloyd’s Syndicates segment business, losses are initially estimated using the loss assumptions by risk category 
incorporated into the business plan submitted to Lloyd’s with consideration given to loss experience incurred to date. These 
assumptions were influenced by loss results reflected in Lloyd’s historical data for similar risks. As losses are reported and 
resolved and loss experience becomes more credible from a statistical perspective, actual loss experience is incorporated into 
the estimates.

Certain of the methodologies utilized to estimate the ultimate losses for each partition of the reserve consider the actual 

amounts paid. Paid data is particularly influential when a large portion of known claims have been closed, as is the case for 
older accident years. In selecting a point estimate for each partition, management considers the extent to which trends are 
emerging consistently for all partitions and known industry trends. Thus, actual, rather than estimated severity trends are given 
more consideration. If actual severity trends are lower than those estimated at the time that reserves were previously 
established, the recognition of favorable development is indicated. This is particularly true for older accident years where 
actuarial methodologies give more weight to actual loss costs (severity).

The various actuarial methods discussed above are applied in a consistent manner from period to period. In addition, 
ProAssurance performs statistical reviews of claims data such as claim counts, average settlement costs and severity trends 
when establishing the reserve.

Selected point estimates of ultimate losses are utilized to develop estimates of ultimate losses recoverable from reinsurers, 

based on the terms and conditions of ProAssurance’s reinsurance agreements. An overall estimate of the amount receivable 
from reinsurers is determined by combining the individual estimates. ProAssurance’s net reserve estimate is the gross reserve 
point estimate less the estimated reinsurance recovery.

(1) Current year net losses for the year ended December 31, 2019 included incurred losses of $2.1 million related to a loss portfolio
transfer  entered  into  during  2019  in  the  Specialty  P&C  segment.  Current  year  net  losses  in  2018  included  incurred  losses  of
$25.4  million  related  to  a  loss  portfolio  transfer  entered  into  during  the  second  quarter  of  2018,  also  in  the  Specialty  P&C
segment.

(2) Current  year  net  losses  for  the  year  ended  December  31,  2019  included  a  PDR  of  $9.2  million  associated  with  the  unearned
premium of a large national healthcare account's claims-made policy in the Specialty P&C segment. Current year net losses for
the year ended December 31, 2020 included the amortization of the aforementioned $9.2 million PDR which offsets the impact of
the losses incurred associated with the premium earned related to the large national healthcare account's claims-made policy. For
additional information regarding the PDR see Note 7.

(3) During 2020, the aforementioned large national healthcare account did not renew on terms offered by the Company and exercised
its contractual option to purchase extended reporting endorsement or "tail" coverage. As a result, ProAssurance recognized total
current  year  losses  of  $60.0  million  (assumes  a  full  limit  loss)  within  the  Specialty  P&C  segment  for  the  year  ended
December 31, 2020.

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 net favorable loss development recognized in 2020 primarily 
reflected a lower than anticipated claims severity trend (i.e., the average size of a claim) in the Specialty P&C segment, 
primarily related to the 2014 through 2017 accident years. The net favorable development also reflected overall favorable trends 
in claim closing patterns in the Segregated Portfolio Cell Reinsurance and Workers' Compensation Insurance segments. The net 
favorable loss development recognized in the Segregated Portfolio Cell Reinsurance segment primarily related to the 2014 
through 2019 accident years and the net favorable loss development recognized in the Workers' Compensation Insurance 
segment primarily related to the 2014 through 2017 accident years.

The net favorable loss development recognized for the year ended December 31, 2019 primarily reflected overall 
favorable trends in claim closing patterns in the Workers' Compensation Insurance and Segregated Portfolio Cell Reinsurance 
segments, largely offset by net unfavorable loss development recognized in the Specialty P&C segment. The net favorable loss 
development recognized in the Workers' Compensation Insurance segment primarily related to the 2015 and 2016 accident 
years and the net favorable loss development recognized in the Segregated Portfolio Cell Reinsurance segment primarily related 
to the 2015 through 2018 accident years. The net unfavorable loss development recognized in the Specialty P&C segment 
primarily related to accident years 2016 through 2018. The favorable loss development recognized in 2018 primarily reflected a 
lower than anticipated claims severity trend for accident years 2011 through 2015.

Claims Development

ProAssurance establishes its reserve and manages claims activity by coverage, product or line of business and various 
categories of reserves have similar characteristics. Therefore, ProAssurance has aggregated these reserve categories into several 
reserve groups in the following disclosures and tables that provide a more meaningful view of the amount, timing and 
uncertainty of cash flows arising from the liability. At the same time, these reserve groups present a disaggregated view of the 
major elements of the overall loss reserve liability. The reserve groups include HCPL claims-made reserve, HCPL occurrence 
reserve, Medical Technology Liability claims-made reserve, Workers’ Compensation Insurance reserve, Segregated Portfolio 
Cell Reinsurance - workers' compensation reserve, Syndicate 1729 casualty reserve, Syndicate 1729 property insurance reserve 
and Syndicate 1729 property reinsurance reserve. All other loss reserve categories are deemed to be less homogeneous or 
relatively small on a standalone basis and are included in other short-duration lines in the claims development reconciliation.

The composition of the reserve groups is based on similar characteristics with respect to the risks being insured and the 

reporting and payout pattern of the underlying claims. In most instances the groups follow the coverage categorizations used in 
statutory financial reporting for U.S.-domiciled property-casualty insurance companies. 

HCPL claims are disaggregated into those claims covered by claims-made policies and those claims covered by 

occurrence policies. For claims-made policies, 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, even if unknown at that 
time. Claims-made coverage has a short reporting pattern, with virtually all claims known shortly after the end of the policy 
period. Occurrence coverage claims can have an extended reporting pattern, with the time from the loss event until the filing of 
the claim often measured in years, at which point the claims resolution process begins. Although the resolution process and 
time frame is similar once a claim is reported, combining claims from claims-made and occurrence coverage types would result 
in distortion due to the difference in reporting lag. Medical Technology Liability reserves are grouped separately due to the 
nature of the risk, including the potential for mass torts and multiple claims arising out of the same product or service. The 
small amount of Medical Technology Liability occurrence reserves are included in other short-duration lines. 

Workers' compensation reserves in the Workers' Compensation Insurance and the Segregated Portfolio Cell Reinsurance 
segments are each grouped separately due to the difference in the type of coverage provided and the differences in the claims 
resolution process as compared to other liability insurance. The small amount of HCPL reserves in the Segregated Portfolio 
Cell Reinsurance segment are included in other short-duration lines.

Finally, claims arising from the Company's participation in Syndicate 1729 are segregated into casualty (insurance and 

reinsurance), property insurance and property reinsurance groups. Property insurance claims generally have a shorter reporting 
and resolution time frame as compared to most casualty claims. The reporting and resolution patterns of property reinsurance 
claims differs from that of property insurance claims due to predominant coverage of catastrophic loss events on an aggregate 
basis rather than coverage of individual claims. Casualty reinsurance, on the other hand, generally provides coverage on a per-
claim basis and the reporting and resolution time frame for these claims is not substantially different than those arising from 
casualty insurance written by Syndicate 1729. The small amount of reserves associated with the Company's participation in 
Syndicate 6131 related to contingency and special property business are included in other short-duration lines.

ProAssurance has elected to present reserve history for acquired entities in all periods shown in the tables below, 
including periods prior to acquisition. With the exception of the Workers' Compensation Insurance and Segregated Portfolio 
Cell Reinsurance - workers' compensation lines of business, virtually all other acquired entities are captured within the HCPL 
line of business. 

All information prior to 2020 disclosed in the Incurred Claims and Allocated Claim Adjustment Expenses, Net of 
Reinsurance, Cumulative Paid Claims and Allocated Claim Adjustment Expenses, Net of Reinsurance and Average Annual 
Percentage Payout of Incurred Claims by Age, Net of Reinsurance tables that follow is presented as supplementary information. 
The “Cumulative Number of Reported Claims” in the tables that follow includes the combined number of claims for an accident 
year and excludes projected unreported IBNR claims. A claim is considered reported when ProAssurance becomes aware of 
and accepts it for coverage under the terms of the Company's insurance contracts.

Healthcare Professional Liability Reserve

HCPL loss costs are impacted by many factors, including but not limited to the nature of the claim, including whether or 

not the claim is an individual or a mass tort claim, the personal situation of the claimant or the claimant's family, the outcome of 
jury trials, the legislative and judicial climate where any potential litigation may occur, general economic and social conditions 
and, for claims involving bodily injury, the trend of healthcare costs. ProAssurance sets an initial reserve based upon the 
evaluation of the current loss environment including frequency, severity, the expected effect of inflation, general economic and 
social trends, and the legal and political environment. The initial loss ratio for HCPL business has ranged from 87% to 106% in 
recent years and has recently trended towards the higher end of this range due to increased reserve estimates for a large national 
healthcare account as well as increases in loss severity in the broader HCPL industry, including our Specialty line of business.

Medical Technology Liability Reserve

The risks insured in the Medical Technology Liability line of business are more varied, and policies are individually 
priced based on the risk characteristics of the policy and the account. These policies often have substantial deductibles or self-
insured retentions, and the insured risks range from startup operations to large multinational entities. Premiums are established 
using the most recently developed actuarial estimates of losses expected to be incurred based on factors which include: results 
from prior analysis of similar business, industry indications, observed trends and judgment. Claims in this line of business 
primarily involve bodily injury to individuals and are affected by factors similar to those of the HCPL line of business. For the 
Medical Technology Liability line of business, ProAssurance also establishes an initial reserve using a loss ratio approach, 
including a provision in consideration of historical loss volatility that this line of business has exhibited.

Workers' Compensation Insurance Reserve

Many factors affect the ultimate losses incurred for the workers' compensation coverages in the Workers' Compensation 

Insurance segment including, but not limited to, the type and severity of the injury, the age and occupation of the injured 
worker, the estimated length of disability, medical treatment and related costs, and the jurisdiction and workers' compensation 
laws of the injury occurrence. ProAssurance uses various actuarial methodologies in developing the workers’ compensation 
reserve combined with a review of the exposure base generally based upon payroll of the insured. For the current accident year, 
given the lack of seasoned information, the different actuarial methodologies produce results with considerable variability; 
therefore, more emphasis is placed on supplementing results from the actuarial methodologies with trends in exposure base, 
medical expense inflation, general inflation, severity, and claim counts, among other things, to select an expected loss ratio.

Syndicate 1729 Reserve

ProAssurance estimates initial losses using the loss assumptions by risk category incorporated into the business plan 

submitted to Lloyd’s with consideration given to loss experience incurred to date. These assumptions are influenced by loss 
results in Lloyd's historical data for similar risks. In addition, Lloyd's market data for payment patterns is utilized to develop the 
payout patterns in the tables shown below. As the book of business matures and additional loss information becomes available, 
the actual loss experience of Syndicate 1729's book of business will be utilized to a greater extent. This will occur sooner for 
property coverages than for casualty coverages due to the shorter claim reporting and resolution time described above.

Claim count information for assumed reinsurance coverage written by Syndicate 1729 is not meaningful in many 
instances. Certain reinsurance contracts provide aggregate coverage for loss events involving numerous underlying claims, 
resulting in a single claim count for reinsurance purposes, while other reinsurance contracts provide individual per-claim 
coverage. Still others may provide aggregate stop loss coverage based on the total losses or loss ratio of a class of business. As 
a result, claim count information is not included in the Syndicate 1729 Casualty and Syndicate 1729 Property Reinsurance 
tables shown below.

Syndicate 1729 writes coverage in a variety of jurisdictions and currencies, although the majority of its business is in U.S. 
dollars. For purposes of the tables below, ProAssurance has elected to convert losses from their original currency to U.S. dollars 
using the exchange rate as of the end of the current period. This provides the purest trend information with respect to loss 
development, since the amounts in the table are not affected by exchange rate movements.

9. Commitments and Contingencies

ProAssurance is involved in various legal actions related to insurance policies and claims handling including, but not 

limited to, claims asserted by policyholders. These types of legal actions arise in the Company's ordinary course of business 
and, in accordance with GAAP for insurance entities, are considered as a part of the Company's loss reserving process, which is 
described in detail under the heading "Losses and Loss Adjustment Expenses" in the Accounting Policies section in Note 1. 
ProAssurance also has other direct actions against the Company unrelated to its claims activity which are evaluated and 
accounted for as a part of other liabilities. For these corporate legal actions, the Company evaluates each case separately and 
establishes what it believes is an appropriate reserve based on GAAP guidance related to contingent liabilities. As of 
December 31, 2020 there were no material reserves established for corporate legal actions.

As a member of Lloyd's, ProAssurance has obligations to Syndicate 1729 and Syndicate 6131 including a Syndicate 
Credit Agreement and FAL requirements. The Syndicate Credit Agreement is an unconditional revolving credit agreement to 
the Premium Trust Fund of Syndicate 1729 for the purpose of providing working capital with maximum permitted borrowings 
of £30.0 million (approximately $41.0 million at December 31, 2020). The Syndicate Credit Agreement has a maturity date of 
December 31, 2021 and contains an annual auto-renewal feature which allows for ProAssurance to elect to non-renew if notice 
is given at least 30 days prior to the next auto-renewal date, which is one year prior to the maturity date. Under the Syndicate 
Credit Agreement, advances bear interest at 3.8% annually and may be repaid at any time but are repayable upon demand after 
December 31, 2021, subject to extension through the auto-renewal feature. As of December 31, 2020, there were no outstanding 
borrowings under the Syndicate Credit Agreement. ProAssurance provides FAL to support underwriting by Syndicate 1729 and 
Syndicate 6131 and is comprised of investment securities and cash and cash equivalents deposited with Lloyd's with a total fair 
value of approximately $106.2 million at December 31, 2020 (see Note 3). During 2020, ProAssurance received a return of 
approximately $32.3 million of cash and cash equivalents from its FAL balances given the Company's reduced participation in 
the results of Syndicate 1729 for the 2020 underwriting year to 29% from 61%.

ProAssurance has entered into financial instrument transactions that may present off-balance sheet credit risk or market 
risk. These transactions include a short-term loan commitment and commitments to provide funding to non-public investment 
entities. Under the short-term loan commitment, ProAssurance has agreed to advance funds on a 30 day basis to a counterparty 
provided there is no violation of any condition established in the contract. As of December 31, 2020, ProAssurance had total 
funding commitments related to non-public investment entities as well as the short-term loan commitment of approximately 
$196.7 million which included the amount at risk if the full short-term loan is extended and the counterparties default. 
However, the credit risk associated with the short-term loan commitment is minimal as the counterparties to the contract are 
highly rated commercial institutions and to-date have been performing in accordance with their contractual obligations. Of these 
total funding commitments, $0.7 million is related to qualified affordable housing project tax credit investments and is expected 
to be paid as follows: $0.3 million in 2021, $0.3 million in 2022 and 2023 combined and $0.1 million in 2024 and 2025 
combined. ProAssurance’s expected credit losses associated with this short-term loan commitment were nominal in amount as 
of December 31, 2020.

In October 2018, ProAssurance entered into an agreement with a company for a minimum commitment of two years to 

provide data analytics services for certain product lines within the Company's HCPL book of business. In October 2020, 
ProAssurance executed an amendment to this agreement which extended the commitment an additional one year for an annual 
fee of approximately $2.4 million and additional variable quarterly incentive fees based on service utilization metrics prescribed 
in the contract. In addition, the amended agreement includes an optional three-month extension feature if notice is given at least 
30 days prior to the end of the contract. ProAssurance incurred operating expenses associated with this agreement of $4.3 
million and $4.9 million for the years ended December 31, 2020 and 2019, respectively. As of December 31, 2020, the 
remaining commitment under this agreement was estimated to be approximately $1.8 million, which includes estimated variable 
quarterly incentive fees.

ProAssurance has entered into a definitive agreement to acquire NORCAL, an underwriter of medical professional 

liability insurance, subject to the demutualization of NORCAL Mutual, NORCAL's ultimate controlling party. Upon 
satisfaction of the various remaining regulatory approvals required, both companies are anticipating to close the transaction in 
the second quarter of 2021. Subject to NORCAL’s conversion from a mutual company to a stock company, ProAssurance has 
agreed to acquire 100% of the converted company stock in exchange for base consideration of $450 million and contingent 
consideration of up to an additional $150 million depending on the development of NORCAL’s ultimate losses over a three-
year period following the acquisition date. The actual final cost of the transaction could vary due to the ability of NORCAL’s 
policyholders to elect forms of consideration other than stock in the demutualization transaction as provided by California 
law. Those alternative consideration options are tied to an appraised value of NORCAL as determined by the California 
insurance regulator rather than the price per share ProAssurance has agreed to pay for 100% of NORCAL assuming that all 
policyholders elect to receive stock. Further, the transaction is subject to a number of closing conditions, including a maximum 

179

ProAssurance Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2020

threshold for one of the alternative forms of consideration in the demutualization, a minimum threshold for the number of 
NORCAL shares tendered to ProAssurance, and various required regulatory approvals. The Agreement and Plan of Acquisition 
is included as Exhibit 10.19 of this report.

10. Leases

ProAssurance is involved in a number of operating leases primarily for office facilities. Office facility leases have

remaining lease terms ranging from one year to eleven years; some of which include options to extend the leases for up to 
fifteen years, and some of which include an option to terminate the lease within one year. ProAssurance subleases certain office 
facilities to third parties and classifies these leases as operating leases. 

The following table provides a summary of the components of net lease expense as well as the reporting location in the

The Senior Notes are the unsecured obligations of ProAssurance Corporation, due in full in November 2023, unless 
redeemed sooner, with interest payable semiannually. Redemptions may be made prior to maturity, in whole or part, at the 
greater of par or the sum of the present values of the outstanding principal and remaining interest payments calculated at 0.4% 
above the then current rate for U.S. Treasury Notes with a term comparable to the remaining term of the Senior Notes. There 
are no financial covenants associated with the Senior Notes.

Mortgage Loans

During 2017, two of ProAssurance's subsidiaries each entered into ten-year mortgage loans collectively totaling 

$40.5 million (Mortgage Loans) with one lender in connection with the recapitalization of two office buildings. The Mortgage 
Loans, which mature in December 2027, accrue interest at three-month LIBOR plus 1.325% with principal and interest payable 
on a quarterly basis. To manage the Company's exposure to increases in LIBOR on the Mortgage Loans, ProAssurance entered 
into an interest rate cap agreement with a notional amount of $35 million. Per the interest rate cap agreement, the Company is 
entitled to receive cash payments if and when the three-month LIBOR exceeds 2.35%. Additional information on the 
Company's derivative instruments is provided in Note 2.

The Mortgage Loans contain customary representations, covenants and events constituting default, and remedies for 

default. Additionally, the Mortgage Loans carry the following financial covenant:

(1) Each of the two ProAssurance subsidiaries are not permitted to have a leverage ratio of consolidated funded debt
(principally, obligations for borrowed money, obligations for deferred purchase price of property or services,
obligations evidenced by notes, bonds, debentures, standby and commercial letters of credit and contingent obligations
of the subsidiary) to consolidated total capitalization (principally, SAP consolidated net worth plus consolidated funded
debt of the subsidiary) greater than 0.35, determined at the end of each fiscal quarter.

Revolving Credit Agreement

ProAssurance has a Revolving Credit Agreement with seven participating lenders. The Revolving Credit Agreement, 

which expires November 2024, may be used for general corporate purposes, including, but not limited to, short-term working 
capital, share repurchases as authorized by the Board and support for other activities. ProAssurance's Revolving Credit 
Agreement permits borrowings up to $250 million, and has available a $50 million accordion feature which, if successfully 
subscribed, would expand the permitted borrowings to a maximum of $300 million. The Revolving Credit Agreement permits 
ProAssurance to borrow, repay and reborrow from the lenders during the term of the Revolving Credit Agreement. All 
borrowings are required to be repaid prior to the expiration date of the Revolving Credit Agreement. ProAssurance is required 
to pay a commitment fee, ranging from 0.15% to 0.30% based on ProAssurance’s credit ratings, on the average unused portion 
of the credit line during the term of the Revolving Credit Agreement. Borrowings under the Revolving Credit Agreement may 
be secured or unsecured and accrue interest at a selected base rate, adjusted by a margin, which can vary from 0% to 1.88%, 
based on ProAssurance’s credit ratings and whether the borrowing is secured or unsecured. The base rate selected may either be 
the current one-, three- or six-month LIBOR, with the LIBOR term selected fixing the interest period for which the rate is 
effective. If no selection is made, the base rate defaults to the highest of (1) the Prime rate, (2) the Federal Funds rate plus 0.5% 
or (3) the one-month LIBOR plus 1.0%, determined daily. Rates are reset each successive interest period until the borrowing is 
repaid.

The Revolving Credit Agreement contains customary representations, covenants and events constituting default, and 

remedies for default. Additionally, the Revolving Credit Agreement carries the following financial covenants:

(1) ProAssurance is not permitted to have a leverage ratio of consolidated funded indebtedness (principally, obligations for

12. Shareholders’ Equity

At December 31, 2020 and 2019, ProAssurance had 100 million shares of authorized common stock and 50 million shares

of authorized preferred stock. The Board has the authority to determine provisions for the issuance of preferred shares, 
including the number of shares to be issued, the designations, powers, preferences and rights, and the qualifications, limitations 
or restrictions of such shares.

The following is a summary of changes in common shares issued and outstanding during the years ended December 31,

As of December 31, 2020, approximately 1.6 million of ProAssurance's authorized common shares were reserved by the

Board for award or issuance under the incentive compensation plans described in Note 13 and an additional 0.5 million of 
authorized common shares were reserved for the issuance of currently outstanding restricted share and performance share unit 
awards.

Quarterly dividends were paid in the month following the quarter in which they were declared. Dividends declared during 

2020, 2019 and 2018 totaled $24.8 million, $66.7 million and $94.3 million, respectively.

ProAssurance's ability to pay dividends to its shareholders is limited by its holding company structure, to the extent of the 

net assets held by its insurance subsidiaries, as discussed in Note 18. Otherwise, there are no other regulatory restrictions on 
ProAssurance's retained earnings or net income that materially impact its ability to pay dividends. Based on shareholders' equity 
at December 31, 2020, total equity of $266.6 million was free of debt covenant restrictions regarding the payment of dividends. 
However, any decision to pay future cash dividends is subject to the Board’s final determination after a comprehensive review 
of financial performance, future expectations and other factors deemed relevant by the Board.

As of December 31, 2020, Board authorizations for the repurchase of common shares or the retirement of outstanding 

debt of $109.6 million remained 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 as well as the rules of the NYSE.

Other Comprehensive Income (Loss) and Accumulated Other Comprehensive Income (Loss)

The following tables provide a detailed breakout of the components of AOCI and the amounts reclassified from AOCI to 
net income (loss). The tax effects of all amounts in the tables below, except for an immaterial amount of unrealized gains and 
losses on available-for-sale securities held at the Company's U.K. subsidiary, were computed using the enacted U.S. federal 
corporate tax rate of 21%. For the years ended December 31, 2020 and 2019, OCI included a deferred tax expense of $9.6 
million and $14.2 million, respectively, and a deferred tax benefit of $9.6 million for the year ended December 31, 2018.

13. Share-Based Payments

Share-based compensation costs are primarily classified as a component of operating expense.

During 2020, 2019 and 2018, ProAssurance provided share-based compensation to employees utilizing two types of 

awards: restricted share units and performance share units. During 2019 and 2018, ProAssurance also provided share-based 
compensation to employees utilizing purchase match units. The restricted share and performance share awards were made under 
either the ProAssurance Corporation Amended and Restated 2014 Equity Incentive Plan or the ProAssurance Corporation 2008 
Equity Incentive Plan. The Compensation Committee of the Board is responsible for the administration of both plans.

The following table provides a summary of compensation expense and the total related tax benefit recognized during each 

period as well as estimated compensation cost that will be charged to expense in future periods.

The majority of awards are equity classified awards and are charged to expense as an increase to additional paid-in capital 

over the service period (generally the vesting period) associated with the award. However, a nominal amount of awards are 
liability classified awards and are recorded as a liability as they are structured to be settled in cash. As of December 31, 2020, 
share-based compensation expense related entirely to restricted share units. Restricted share and performance share units vest in 
their entirety generally at the end of a three-year period, except for certain restricted share units granted in 2019 which will vest 
at the end of a five-year period, following the grant date based on a continuous service requirement and, for performance share 
units, achievement of a performance objective. Partial vesting is permitted for retirees. All non-vested purchase match units at 
December 31, 2018 were fully vested in the fourth quarter of 2019; previously, units vested over a three-year period based on a 
service requirement with partial vesting permitted for all participants. For the restricted share and purchase match units, a single 
share of ProAssurance common stock is issued per vested unit. For performance share units, the number of shares of 
ProAssurance common stock issued per vested unit varies based on performance goals achieved. For equity classified awards, 
units sufficient to satisfy required tax withholdings are paid in cash rather than in shares of ProAssurance common stock. 
Liability classified awards, which are nominal in amount, are settled in cash at the end of the vesting period. 

Restricted Share Units

Activity for restricted share units during 2020, 2019 and 2018 is summarized below. Grant date fair values are based on 

the market value of a share of ProAssurance common stock on the date of grant less the estimated net present value of expected 
dividends during the vesting period.

Performance Share Units

Performance share units vest only if minimum performance objectives are met, and the number of units earned varies 

from 50% to 200% of a base award depending upon the degree to which stated performance objectives are achieved. 
Performance share unit activity for 2020, 2019 and 2018 is summarized below. The table reflects the base number of units; 
actual awards that vest depend upon the extent to which performance objectives are achieved. Grant date fair values are based 
on the market value of a share of ProAssurance common stock on the date of grant less the estimated net present value of 
expected dividends during the vesting period.

The aggregate grant date fair value of performance share units (base level) vested and released in 2019 and 2018 totaled 

$2.7 million and $4.5 million, respectively; there were no performance share units vested and released in 2020 as minimum 
performance objectives were not achieved. The aggregate intrinsic value of performance share units (base level) vested and 
released in 2019 and 2018 (including units paid in cash to cover tax withholdings) totaled $2.6 million and $5.0 million, 
respectively. The weighted average level at which the vested units were issued was 95% and 125% during 2019 and 2018, 
respectively, based on performance levels achieved.

Purchase Match Units

The ProAssurance Corporation 2011 Employee Stock Ownership Plan provided a purchase match unit for each share of 
ProAssurance common stock purchased with contributions by eligible plan participants, with participant contributions subject 
to a $5,000 annual limit per participant. During 2017, the ProAssurance Corporation 2011 Employee Stock Ownership Plan was 
discontinued and the existing non-vested purchase match units were fully vested in the fourth quarter of 2019. Purchase match 
unit activity during 2019 and 2018 is summarized below. Grant date fair values are based on the market value of a 
ProAssurance common share on the date of grant less the estimated net present value of expected dividends during the vesting 
period.

14. Variable Interest Entities

ProAssurance holds passive interests in a number of entities that are considered to be VIEs under GAAP guidance.

ProAssurance's VIE interests principally consist of interests in LPs/LLCs formed for the purpose of achieving diversified equity 
and debt returns. ProAssurance's VIE interests, carried as a part of investment in unconsolidated subsidiaries, totaled 
$282.2 million at December 31, 2020 and $309.0 million at December 31, 2019.

ProAssurance does not have power over the activities that most significantly impact the economic performance of these 

VIEs and thus is not the primary beneficiary. 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. Therefore, ProAssurance has not consolidated 
these VIEs. ProAssurance’s involvement with each VIE is limited to its direct ownership interest in the VIE. Except for the 
funding commitments disclosed in Note 9, ProAssurance has no arrangements with any of the VIEs to provide other financial 
support to or on behalf of the VIE. At December 31, 2020, ProAssurance’s maximum loss exposure relative to these 
investments was limited to the carrying value of ProAssurance’s investment in the VIE.

15. Earnings (Loss) Per Share

Diluted weighted average shares is calculated as basic weighted average shares plus the effect, calculated using the
treasury stock method, of assuming that restricted share units, performance share units and purchase match units have vested.

outstanding to its diluted weighted average number of common shares outstanding:

The diluted weighted average number of common shares outstanding for the years ended December 31, 2020 and 2018 

excludes approximately 114,000 and 2,000, respectively, common share equivalents issuable under the Company's stock 
compensation plans, as their effect would be antidilutive. There were no antidilutive common share equivalents for the year 
ended December 31, 2019.

Dilutive common share equivalents are reflected in the earnings (loss) per share calculation while antidilutive common 

share equivalents are not reflected in the earnings (loss) per share calculation. For the year ended December 31, 2020, all 
incremental common share equivalents were not included in the computation of diluted earnings (loss) per share because to do 
so would have been antidilutive.

16. Segment Information

ProAssurance's segments are based on the Company's internal management reporting structure for which financial results

are regularly evaluated by the Company's CODM to determine resource allocation and assess operating performance. The 
Company continually assesses its internal management reporting structure and information evaluated by its CODM to 
determine whether any changes have occurred that would impact its segment reporting structure. The Company operates in five 
segments that are organized around the nature of the products and services provided: Specialty P&C, Workers' Compensation 
Insurance, Segregated Portfolio Cell Reinsurance, Lloyd's Syndicates and Corporate. A description of each of ProAssurance's 
five operating and reportable segments follows.

Specialty P&C includes professional liability insurance and medical technology liability insurance. Professional liability 
insurance is primarily comprised of medical professional liability products offered to healthcare providers and institutions. The 
Company also offers, to a lesser extent, professional liability insurance to attorneys and their firms. Medical technology liability 
insurance is offered to medical technology and life sciences companies that manufacture or distribute products including 
entities conducting human clinical trials. In addition, the Company also offers custom alternative risk solutions including loss 
portfolio transfers, assumed reinsurance and captive cell programs for healthcare professional liability insureds. For the 
alternative market captive cell programs, the Specialty P&C segment cedes either all or a portion of the premium to certain 
SPCs in the Company's Segregated Portfolio Cell Reinsurance segment.

Workers' Compensation Insurance includes workers' compensation insurance products which are provided primarily to 

employers with 1,000 or fewer employees. The segment's products include guaranteed cost policies, policyholder dividend 
policies, retrospectively-rated policies, deductible polices and alternative market solutions. Alternative market program 
premiums include program design, fronting, claims administration, risk management, SPC rental, asset management and SPC 
management services. Alternative market program premiums are 100% ceded to either SPCs in the Company's Segregated 
Portfolio Cell Reinsurance segment or, to a limited extent, to a captive insurer unaffiliated with ProAssurance.

Segregated Portfolio Cell Reinsurance includes the results (underwriting profit or loss, plus investment results, net of U.S. 

federal income taxes) of SPCs at Inova Re and Eastern Re, the Company's Cayman Islands SPC operations. Each SPC is 
owned, fully or in part, by an agency, group or association, and the results of the SPCs are attributable to the participants of that 
cell. ProAssurance participates to a varying degree in the results of selected SPCs. SPC results attributable to external cell 
participants are reflected as SPC dividend expense (income) in the Segregated Portfolio Cell Reinsurance segment and in 
ProAssurance's Consolidated Statements of Income and Comprehensive Income. In addition, the Segregated Portfolio Cell 
Reinsurance segment includes the investment results of the SPCs as the investments are solely for the benefit of the cell 
participants, and investment results attributable to external cell participants are reflected in the SPC dividend expense (income). 
The SPCs assume workers' compensation insurance, healthcare professional liability insurance or a combination of the two 
from the Company's Workers' Compensation Insurance and Specialty P&C segments.

Lloyd's Syndicates includes results from ProAssurance's participation in Lloyd's of London Syndicate 1729 and Syndicate 
6131. The results of this segment are normally reported on a quarter lag, except when information is available that is material to 
the current period. Furthermore, investment results associated with the majority of investment assets solely allocated to Lloyd's 
Syndicate operations and certain U.S. paid administrative expenses are reported concurrently as that information is available on 
an earlier time frame. Syndicate 1729 underwrites risks over a wide range of property and casualty insurance and reinsurance 
lines in both the U.S. and international markets while Syndicate 6131 focuses on contingency and specialty property business, 
also within the U.S. and international markets. For the 2020 underwriting year, ProAssurance decreased its participation in the 
results of Syndicate 1729 to 29% from 61%; however, due to the quarter lag these changes were not reflected in the Company's 
results until the second quarter of 2020. Syndicate 6131 is an SPA that underwrites on a quota share basis with Syndicate 1729. 
Effective July 1, 2020, Syndicate 6131 entered into a six-month quota share reinsurance agreement with an unaffiliated insurer. 
Under this agreement, Syndicate 6131 ceded essentially half of the premium assumed from Syndicate 1729 to the unaffiliated 
insurer; the agreement was non-renewed on January 1, 2021. Due to the quarter lag, the effect of this reinsurance arrangement 
was not reflected in our results until the fourth quarter of 2020.  

Corporate includes ProAssurance's investment operations, other than those reported in the Company's Segregated 

Portfolio Cell Reinsurance and Lloyd's Syndicates segments, interest expense and U.S. income taxes. The segment also includes 
non-premium revenues generated outside of the Company's insurance entities and corporate expenses. 

The accounting policies of the segments are described in Note 1. ProAssurance evaluates the performance of its Specialty 
P&C and Workers' Compensation Insurance segments based on before tax underwriting profit or loss. ProAssurance evaluates 
the performance of its Segregated Portfolio Cell Reinsurance segment based on operating profit or loss, which includes 
investment results of investment assets solely allocated to SPC operations, net of U.S. federal income taxes. Performance of the 
Lloyd's Syndicates segment is evaluated based on operating profit or loss, which includes investment results of investment 

189

ProAssurance Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2020

assets solely allocated to Lloyd's Syndicate operations, net of U.K. income tax expense. Performance of the Corporate segment 
is evaluated based on the contribution made to consolidated after-tax results. ProAssurance accounts for inter-segment 
transactions as if the transactions were to third parties at current market prices. Assets are not allocated to segments because 
investments, other than the investments discussed above that are solely allocated to the Segregated Portfolio Cell Reinsurance 
and Lloyd's Syndicates segments, and other assets are not managed at the segment level. The tabular information that follows 
shows the financial results of the Company's reportable segments reconciled to results reflected in the Consolidated Statements 
of Income and Comprehensive Income. ProAssurance does not consider asset impairments, including goodwill and intangible 
asset impairments, in assessing the financial performance of its operating and reportable segments, and thus are included in the 
reconciliation of segment results to consolidated results.

(3) In  ProAssurance's  December  31,  2019  and  2018  reports  on  Form  10-K,  underwriting,  policy  acquisition  and  operating  expenses  for  the  years  ended
December 31, 2019 and 2018 included a provision for U.S. federal income taxes of $1.1 million and $0.4 million, respectively, for SPCs at Inova Re that 
have  elected  to  be  taxed  as  U.S.  taxpayers  (see  footnote  2).  Beginning  in  2020,  this  tax  provision  is  now  presented  as  a  separate  line  item  on  the 
Consolidated  Statements  of  Income  and  Comprehensive  Income  as  SPC  U.S.  federal  income  tax  expense.  To  conform  to  the  current  year  presentation,
ProAssurance has recast underwriting, policy acquisition and operating expenses for the years ended December 31, 2019 and 2018.

17. Benefit Plans

ProAssurance maintains the ProAssurance Savings Plan that provides a vehicle for eligible employees to build retirement

income. For the first half of 2020 and for the years ended December 31, 2019 and 2018, ProAssurance provided employer 
contributions to the plan of up to 10% of eligible contributions for qualified employees. Given the Company’s current earnings 
profile and the effects that underlying conditions in the broader insurance marketplace continue to have on the Company’s 
results, the maximum employer contribution to the plan was reduced to 5% from 10% of eligible contributions for qualified 
employees effective July 2020. ProAssurance incurred expense related to the ProAssurance Savings Plan of $5.5 million, $7.2 
million and $7.0 million during the years ended December 31, 2020, 2019 and 2018, respectively.

ProAssurance also maintains the ProAssurance Plan that allows eligible management employees to defer a portion of their 

current salary. ProAssurance incurred nominal expense related to the ProAssurance Plan in each of the years ended 
December 31, 2020, 2019 and 2018. ProAssurance deferred compensation liabilities totaled $30.3 million and $26.8 million at 
December 31, 2020 and 2019, respectively. The liabilities included amounts due under the ProAssurance Plan and amounts due 
under individual agreements with current or former employees.

18. Statutory Accounting and Dividend Restrictions

ProAssurance’s domestic U.S. insurance subsidiaries are required to file statutory financial statements with state insurance

regulatory authorities, prepared based upon SAP prescribed or permitted by regulatory authorities. ProAssurance did not use 
any prescribed or permitted SAP that differed from the NAIC's SAP at December 31, 2020, 2019 or 2018. The most significant 
differences between net income (loss) prepared in accordance with GAAP and statutory net income (loss) are generally due to: 
(a) policy acquisition and certain software and equipment costs which are deferred under GAAP but expensed for statutory
purposes, (b) certain deferred income taxes which are recognized under GAAP but are not recognized for statutory purposes, (c)
net unrealized gains or losses which are included in shareholders' equity related to available-for-sale fixed maturity securities
carried at fair value under GAAP but are principally carried at amortized cost for statutory purposes and (d) accounting for
goodwill and intangible assets.

The NAIC specifies risk-based capital requirements for property and casualty insurance providers. At December 31, 2020, 

actual statutory capital and surplus for each of ProAssurance’s insurance subsidiaries exceeded the minimum regulatory 
requirements. Net income (loss) and capital and surplus of ProAssurance’s insurance subsidiaries on a statutory basis are shown 
in the following table.

At December 31, 2020, $1.1 billion of ProAssurance's consolidated net assets were held at its domestic insurance 
subsidiaries, of which approximately $87 million are permitted to be paid as dividends over the course of 2021 without prior 
approval of state insurance regulators. 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 capital and surplus of the insurance subsidiary. In addition, ProAssurance makes the decision to pay 
dividends from an insurance subsidiary based on the capital needs of that subsidiary and may pay less than the permitted 
dividend or may also request permission to pay an additional amount (an extraordinary dividend).

Basis of Presentation

The registrant-only financial statements should be read in conjunction with ProAssurance Corporation’s Consolidated 

Financial Statements and Notes thereto.

At December 31, 2020 and 2019, PRA investment in subsidiaries is stated at the initial consolidation value plus equity in 

the undistributed earnings of subsidiaries since the date of acquisition.

ProAssurance Corporation has a management agreement with several of its insurance subsidiaries whereby ProAssurance 
Corporation charges the subsidiaries a management fee for various management services provided to the subsidiary. Under the 
arrangement, the expenses associated with such services remain as expenses of ProAssurance Corporation and the management 
fee charged is reported as an offset to ProAssurance Corporation expenses.

Portfolio Cell Reinsurance and Lloyd's Syndicates segments, and other assets are not managed at the segment level. See Note 16 of the
Notes to Consolidated Financial Statements for additional information.
(2) In ProAssurance's December 31, 2019 and 2018 reports on Form 10-K, underwriting, policy acquisition and operating expenses for the
years ended December 31, 2019 and 2018 included a provision for U.S. federal income taxes of $1.1 million and $0.4 million,
respectively, for SPCs at Inova Re that have elected to be taxed as U.S. taxpayers. Beginning in 2020, this tax provision is now presented
as a separate line item on the Consolidated Statements of Income and Comprehensive Income as SPC U.S. federal income tax expense.
To conform to the current year presentation, ProAssurance has recast underwriting, policy acquisition and operating expenses for the
years ended December 31, 2019 and 2018.

Non-GAAP Financial Measures

Appendix A

Non-GAAP operating income (loss) is a financial measure that is widely used to evaluate performance within the 
insurance sector. In calculating Non-GAAP operating income (loss), we have excluded the effects of the items listed in 
the following table that do not reflect normal results. We believe Non-GAAP operating income (loss) presents a useful 
view of the performance of our insurance operations, however it should be considered in conjunction with net income 
(loss) computed in accordance with GAAP.

Reconciliation of net income (loss) to Non-GAAP operating income (loss):

(1) Net realized investment gains (losses) on investments related to SPCs are recognized in our Segregated Portfolio Cell Reinsurance segment. SPC 
results, including any realized gain or loss, that are attributable to external cell participants are reflected in the SPC dividend expense (income). 
To be consistent with our exclusion of net realized investment gains (losses) recognized in earnings, we are excluding the portion of net realized 
investment gains (losses) that is included in the SPC dividend expense (income) which is attributable to the external cell participants.

(2) The statutory tax rate for 2018 through 2020 is 21% as compared to 35% for 2017 and 2016, associated with the taxable or tax deductible items 
listed above. The taxes associated with the net realized investment gains (losses) related to SPCs in our Segregated Portfolio Cell Reinsurance 
segment are paid by the individual SPCs and are not included in our consolidated tax provision or net income (loss); therefore, both the net 
realized investment gains (losses) from our Segregated Portfolio Cell Reinsurance segment and the adjustment to exclude the portion of net 
realized investment gains (losses) included in the SPC dividend expense (income) in the table above are not tax effected. The portion of 2020 
goodwill impairment loss that is tax deductible was tax affected at the statutory tax rate (21%). The remaining portion of the 2020 goodwill 
impairment loss is not tax deductible and therefore had no associated income tax benefit. 

(3) Due to tax reform enacted by the TCJA, we remeasured our deferred tax assets and liabilities based on the newly enacted tax rate of 21% and 
recognized a charge of $6.5 million, which is included as a component of income tax expense from continuing operations for the year ended 
December 31, 2017. In addition, we made a reasonable estimate of the effects on our deferred tax asset balances at December 31, 2017 as it 
related to the limitation on the future deductibility on certain executive compensation and recorded a provisional charge to income tax expense of 
$3.5 million for the year ended December 31, 2017. During 2018, we were able to complete our accounting for the impact of the TCJA on our 
December 31, 2017 deferred tax asset balances related to executive compensation; no measurement period adjustment was recorded in 2018 as a 
result.
