We own and operate a group of specialty insurance and reinsurance companies.For the year ended December 31, 2018, approximately 67.6% of our group-wide gross written premiums originated from the U.S. excess and surplus (“E&S”)lines market. Substantially all of our business is casualty insurance and reinsurance, and for the year ended December 31, 2018, we derived 98.5% of ourgroup-wide gross written premiums from casualty insurance and reinsurance. Our objective is to generate compelling returns on tangible equity, whilelimiting underwriting and investment volatility. We seek to accomplish this by consistently earning profits from insurance and reinsurance underwriting andgenerating meaningful risk-adjusted investment returns, while managing our capital opportunistically. Our group includes three specialty property-casualtyinsurance and reinsurance segments: Excess and Surplus Lines, Specialty Admitted Insurance and Casualty Reinsurance.We write very little property or catastrophe insurance and no property catastrophe reinsurance. For the year ended December 31, 2018, propertyinsurance and reinsurance represented 1.5% of our gross written premiums. When we do write property insurance, we buy reinsurance to significantly mitigateour risk. We have structured our reinsurance arrangements so that our modeled net pre-tax loss from a 1/1000 year probable maximum loss ("PML") event isno more than $10.0 million on a group-wide basis.We report our business in four segments: Excess and Surplus Lines, Specialty Admitted Insurance, Casualty Reinsurance and Corporate and Other.The Excess and Surplus Lines segment sells E&S commercial lines liability and property insurance in every U.S. state and the District of Columbiathrough James River Insurance Company (“James River Insurance”) and its wholly-owned subsidiary, James River Casualty Company (“James RiverCasualty”). James River Insurance and James River Casualty are both non-admitted carriers. Non-admitted carriers writing in the E&S market are not boundby most of the rate and form regulations imposed on standard market companies, allowing them flexibility to change the coverage terms offered and the ratecharged without the time constraints and financial costs associated with the filing of such changes with state regulators. In 2018, the average account in thissegment (excluding commercial auto policies) generated annual gross written premiums of approximately $20,000. The Excess and Surplus Lines segmentdistributes primarily through wholesale insurance brokers. Members of our management team have participated in this market for over three decades and havelong-standing relationships with the wholesale brokers who place E&S lines accounts. The Excess and Surplus Lines segment produced 56.3% of our grosswritten premiums and 74.9% of our net written premiums for the year ended December 31, 2018.The Specialty Admitted Insurance segment has two areas of focus. We write a select book of workers’ compensation coverage for building trades,healthcare employees and light manufacturing, among other light to medium hazard risks in select Southeastern and Eastern U.S. states, as well as frontingbusiness which has become a significant element of our revenues and profits in this segment. Starting in 2017, we have de-emphasized the program business,as we believe fronting offers better risk adjusted return potential. In our fronting business, we retain a small percentage of the risk, generally 10% or less, andseek to earn fee income by allowing other carriers and producers to access our licensure, ratings, and underwriting and claims expertise. In our programbusiness, our historic net retention was more than 10%. The Specialty Admitted Insurance segment accepts applications for insurance from a variety ofsources, including independent retail agents, program administrators and managing general agents (“MGAs”). The Specialty Admitted Insurance segmentproduced 32.1% of our gross written premiums and 7.3% of our net written premiums for the year ended December 31, 2018.The Casualty Reinsurance segment provides proportional and working layer casualty reinsurance to third parties and to our U.S.-based insurancesubsidiaries. Typically, we structure our reinsurance contracts (also known as treaties) as quota share arrangements, with loss mitigating features, such ascommissions that adjust based on underwriting results. We frequently include risk mitigating features in our working layer excess of loss treaties, such as paidreinstatements, which allow the ceding company to capture a greater percentage of the profits should the business prove more profitable than expected, oralternatively, with additional premiums should the business incur higher than expected losses. We believe these structures best align our interests with theinterests of our cedents. On a premium volume basis, treaties with loss mitigation features including sliding scale ceding commissions represented 81.7% ofthe gross premiums written by our Casualty Reinsurance segment during 2018. We typically do not assume large individual risks in our CasualtyReinsurance segment, nor do we write property catastrophe reinsurance. Most of the policies assumed by our Casualty Reinsurance segment have a $1.0million per occurrence limit, and we typically assume only a portion of that exposure. We believe this structure reduces volatility in our underwriting results.We do not assume stand-alone third-party property business at our Casualty Reinsurance segment, but we do have a small amount of assumed business withancillary property exposure. 83.7% of premiums written by our Casualty Reinsurance segment during 2018 were general liability accounts assumed fromE&S carriers. The Casualty Reinsurance segment distributes through4TABLE OF CONTENTSreinsurance brokers and produced 11.6% of our gross written premiums and 17.8% of our net written premiums for the year ended December 31, 2018.The Casualty Reinsurance segment writes business through two entities, JRG Reinsurance Company Ltd ("JRG Re") and Carolina Re Ltd ("CarolinaRe"). Through December 31, 2017, we had intercompany reinsurance agreements under which we ceded 70% of the net written premiums of our U.S.subsidiaries (after taking into account third-party reinsurance) to JRG Re. Effective January 1, 2018, we generally discontinued ceding 70% of our U.S.-written premiums to JRG Re and instead ceded 70% of our U.S.-written premiums to Carolina Re. This business is ceded under proportional, or quota-share,reinsurance treaties that provide for an arm’s length ceding commission. We exclude the effects of intercompany reinsurance agreements from thepresentation of our segment results, consistent with the way we manage the Company. At December 31, 2018, 54.9% of our cash and invested assets wereheld at JRG Re, which benefits from a favorable operating environment, including an absence of corporate income or investment taxes.On December 22, 2017, the United States enacted Public Law No. 115-97, informally titled the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Actsignificantly changed the U.S. Internal Revenue Code of 1986, as amended (the “Code”), including by reducing the U.S. corporate income tax rate from 35%to 21% and imposing a base erosion and anti-abuse tax (“BEAT”). In response to the Tax Act, we made changes to our structure in 2018 to minimize theimpact of BEAT that included the formation of Carolina Re, a Bermuda-domiciled, wholly-owned subsidiary of James River Group, Inc. Carolina Re is aClass 3A reinsurer and made an irrevocable election to be taxed as a U.S. domestic corporation under Section 953(d) of the Code effective January 1, 2018.Carolina Re also entered into a stop loss reinsurance agreement with JRG Re.The Corporate and Other segment consists of the management and treasury activities of our holding companies and interest expense associated with ourdebt.In 2018, our operating subsidiaries wrote $1,166.8 million of gross written premiums, allocated by segment and underlying market as follows:Gross Written Premiums by Segment Gross WrittenPremiumsYear EndedDecember 31, 2018 % of Total (in thousands) Excess and Surplus Lines segment $656,538 56.3%Specialty Admitted Insurance segment 374,346 32.1%Casualty Reinsurance segment 135,889 11.6% $1,166,773 100.0%Gross Written Premiums by Market Non-admitted markets $788,781 67.6%Admitted markets 377,992 32.4% $1,166,773 100.0%The A.M. Best Company (“A.M. Best”) financial strength rating for our group’s regulated insurance subsidiaries is “A” (Excellent). This rating reflectsA.M. Best’s evaluation of our insurance subsidiaries’ financial strength, operating performance and ability to meet obligations to policyholders and is not anevaluation directed towards the protection of investors.The financial strength ratings assigned by A.M. Best have an impact on the willingness of brokers and agents to submit applications for insurance andreinsurance to our regulated subsidiaries and on the risk profiles of the submissions for insurance that our subsidiaries receive. The “A” (Excellent) ratingsassigned to our insurance and reinsurance subsidiaries are consistent with our business plans and we believe allow our subsidiaries to actively pursuerelationships with the agents and brokers identified in their marketing plans.Our HistoryIn 2002, a group of experienced insurance executives with a history of starting and operating profitable specialty insurance operations created JamesRiver Group, Inc. (“James River Group”). James River Group was listed on the NASDAQ Stock Market (symbol: JRVR) in 2005 and consistently producedattractive underwriting results. James River Group had two insurance company subsidiaries, James River Insurance and Stonewood Insurance Company(“Stonewood Insurance”). Both of these subsidiaries as well as James River Group remain subsidiaries of ours.5TABLE OF CONTENTSIn 2007, James River Group’s management team decided to enhance James River Group’s long-term profitability by combining the earnings power ofJames River Group with the efficiency of an affiliated Bermuda domiciled reinsurer. A group of investors led by affiliates of D. E. Shaw & Co., L.P., a globalinvestment and technology firm, acquired James River Group, at which point it ceased trading as a public company. Simultaneously, the investors andmanagement founded and capitalized JRG Re, and we began the process of building our present company.In December 2014, we completed an initial public offering of our common shares (the “IPO”). Affiliates of D. E. Shaw & Co., L.P. and anotherinstitutional investor and its affiliate sold all of the common shares in the IPO. Neither the Company nor any of its management or other shareholders soldshares in the IPO. D.E. Shaw & Co., L.P. sold its shares in our Company in a series of secondary offerings in 2016, 2017 and 2018 and no longer owns any ofour shares.Our Competitive StrengthsWe believe we have the following competitive strengths:Proven and Strong Management Team Whose Financial Interests are Aligned with Shareholders. Our Chief Executive Officer, Robert P. Myron, whohas served in various capacities with our group since 2010, has a history of working in a senior management capacity in the insurance and reinsuranceindustries in both the United States and Bermuda. Mr. Myron has significant experience working in operations, finance and underwriting of several differentinsurance and reinsurance companies over the course of his career. Our Chief Financial Officer, Sarah C. Doran, joined our group in January 2017. She hassignificant experience with capital markets and corporate development related to the insurance and financial services industry. Ms. Doran has a history ofworking in a senior capacity in finance and advisory both within the insurance and reinsurance industry and for various investment banks.The President and Chief Executive Officer of our Excess and Surplus Lines segment, Richard Schmitzer, who has been with our group since July 2009,has a history of working in a senior management capacity in the E&S lines industry. Mr. Schmitzer has significant experience working in underwriting andoperations of several different insurance companies over the course of his career.The President and Chief Executive Officer of our Specialty Admitted Insurance segment, Terry McCafferty, has extensive experience as an insuranceunderwriter, operator and executive, and has deep experience and industry knowledge to continue to build out our business initiatives in the fronting andspecialty admitted risk business.The President and Chief Executive Officer of our Casualty Reinsurance segment, Daniel Heinlein, has significant experience as a broker and underwriterof specialty reinsurance risks, particularly in the small account market where we concentrate.The Non-Executive Chairman of the Company’s Board of Directors (the “Board”), J. Adam Abram, has a history of forming and managing profitablespecialty insurance companies. He was a founder of the Company and a predecessor company, and he remains highly engaged as a key strategic contributor.All members of our executive management and senior management have equity grants that we believe help align their interests with those of our long-term shareholders.Broad Underwriting Expertise. We strive to be innovative in tailoring our products to provide solutions for our distribution partners and insureds, andwe are willing to entertain insuring many types of risk classifications. As a result, we believe we are a “go to” market for a wide variety of risks. We are able tostructure solutions for our insureds and the wholesale brokers with whom we work because of our deep technical expertise and experience in the niches andspecialties we underwrite.Emphasis on Lowering Volatility. We earn our profits by taking underwriting and investment risk. We underwrite many classes of insurance and investin many types of assets. We actively seek to avoid underwriting business or making investments that expose us to an unacceptably high risk of large losses.We believe we have minimal exposure to material property risks and did not have material losses from property risks during 2018.We seek to limit our catastrophic underwriting exposure in all areas, but in particular to property risks and catastrophic events. Our U.S. primarycompanies purchase reinsurance from unaffiliated reinsurers to reduce our net exposure to any one risk or occurrence. In addition, our policy forms andpricing are subject to regular formal analysis to ensure we are insuring the types of risks we intend and that we are being appropriately compensated fortaking on those risks. When we write reinsurance, we seek to avoid catastrophic risks and contractually limit the amount of exposure we have on any one riskor occurrence. We prefer to structure our assumed reinsurance treaties as proportional or quota share reinsurance, which is generally less volatile than excessof loss or catastrophe reinsurance. We believe this structure aligns our interests with those of the ceding company.Meaningful Risk Adjusted Investment Returns. We seek to generate meaningful contributions to company profitability from our investment portfolio.We attempt to follow a diversified strategy that emphasizes the preservation of our invested6TABLE OF CONTENTSassets, provides adequate liquidity for the prompt payment of claims and produces attractive results for our shareholders. Within that context, we seek toimprove risk-adjusted returns in our investment portfolio by allocating a portion of our portfolio to investments where we take measured risks based upondetailed knowledge of certain niche asset classes. Investment grade fixed maturity securities make up the majority of our investment portfolio, and we arecomfortable allocating a portion of our assets to non-traditional investments. Our non-traditional investments have generally not included a meaningfulallocation to listed common equities. We consider non-traditional investments to include investments that are (1) unrated bond or fixed income securities,(2) non-listed equities or (3) investments that generally have less liquidity than rated bond or fixed income securities or listed equities. Non-traditionalinvestments represented 19.9% of our total invested assets at December 31, 2018, consisting of syndicated bank loans (15.6%) and other invested assets(4.3%) that include interests in limited liability companies that invest in renewable energy opportunities, limited partnerships that invest in debt or equitysecurities, notes receivable for renewable energy projects, and a private debt security. While we are willing to make investments in non-traditional types ofinvestments, we seek to avoid asset classes and investments that we do not understand. The weighted average credit rating of our portfolio of fixed maturitysecurities, bank loans and redeemable preferred stocks as of December 31, 2018 was “A”. At December 31, 2018, the average duration of our investmentportfolio was 3.4 years.Talented Underwriters and Operating Leadership. The managers of our 15 underwriting divisions have an average of over 25 years of industryexperience, substantial subject matter expertise and deep technical knowledge. They have been successful and profitable underwriters for us in the specialtycasualty insurance and reinsurance sectors. Our segment presidents all have extensive backgrounds and histories working in management capacities inspecialty casualty insurance and reinsurance.Robust Technology and Data Capture. We seek to ground our underwriting decisions in reliable historical data and technical evaluation of risks. Ourunderwriters utilize intuitive systems and differentiated technologies, many of which are proprietary. We have implemented processes to capture extensivedata on our book of business, before, during and after the underwriting analysis and decision. We use the data we collect to inform and, we believe, improveour judgment about similar risks as we refine our underwriting criteria. We use the data we collect in regular formal review processes for each of our lines ofbusiness and significant reinsurance treaties.Focus on Small and Medium-Sized Casualty Niche and Specialty Business. We believe that small and medium-sized casualty accounts, in niche areaswhere we focus, are consistently among the most attractive subsets of the property-casualty insurance and reinsurance market. We think the uniquecharacteristics of the risks within these markets require each account to be individually underwritten in an efficient manner.Many carriers have chosen either to reject business that requires individual underwriting or have attempted to automate the underwriting of this highlyvariable business. While we use technology to greatly reduce the cost of individually underwriting these accounts in our Excess and Surplus Lines andSpecialty Admitted Insurance segments, we continue to have our underwriters make individual judgments regarding the underwriting and pricing ofaccounts. Our experience leads us to believe this approach is more likely to produce consistent results over time and across markets. In addition, while webelieve that the insurance and reinsurance industry is generally overcapitalized at this time, we are currently achieving attractive, moderately increasing ratesin our Excess and Surplus Lines and Specialty Admitted Insurance segments, which two segments combined represented 88.4% of our gross written premiumsand 82.2% of our net written premiums for the twelve months ended December 31, 2018. We believe that there are compelling opportunities for measured butprofitable growth in many sectors of the insurance markets we target.Active Claims Management. Our U.S.-based primary insurance companies actively manage claims as part of keeping losses and loss adjustmentexpenses low. We attempt to investigate thoroughly and settle promptly all covered claims, which we generally accomplish through direct contact with theinsured and other affected parties. We have historically been able to close approximately 95% of claims within five years, and as of December 31, 2018, ourreserves for claims incurred but not reported (“IBNR”) were 61.5% of our total net loss reserves.Efficient Operating Platform. We have what we believe to be a sector leading expense ratio, as we carefully manage personnel and all other coststhroughout our group while growing our business. For the year ended December 31, 2018, our expense ratio was 23%. Additionally, our Bermuda domicileand operations provide for capital flexibility and an efficient tax structure. At December 31, 2018, 54.9% of our cash and invested assets were held at JRG Re,which benefits from a favorable operating environment, including an absence of corporate income or investment taxes.Our StrategyWe believe our approach to our business will help us achieve our goal of generating compelling returns on tangible equity while limiting volatility inour financial results. This approach involves the following:Generate Consistent Underwriting Profits. We seek to make underwriting profits each and every year. We attempt to find ways to grow in markets thatwe believe to be profitable, but are less concerned about growth than maintaining profitability in7TABLE OF CONTENTSour underwriting activities (without regard to investment income). Accordingly, we are willing to reduce the premiums we write when we cannot achieve thepricing and contract terms we believe are necessary to meet our financial goals.Maintain a Strong Balance Sheet. Balance sheet integrity is key to our long-term success. In order to maintain balance sheet integrity, we seek toestimate the amount of future obligations, especially reserves for losses and loss adjustment expenses, in a consistent and appropriate fashion. FromDecember 31, 2007 through December 31, 2018, we have experienced $106.0 million of cumulative net favorable reserve development.Earn a Meaningful Contribution from Investments. We seek to earn a meaningful contribution to our overall returns from our investment portfolioactivities each year. We attempt to balance the preservation of assets, liquidity needs and mitigation of volatility with returns across our portfolio. We believeour diversified portfolio and ability to source investment opportunities positions us well to generate returns while balancing the importance of maintaining astrong balance sheet.Focus on Specialty Insurance Markets and Fee Income. By focusing on specialty markets in which our underwriters have particular expertise and inwhich we have fewer competitors than in standard markets, we have greater flexibility to price and structure our products in accordance with our underwritingstrategy. We believe underwriting profitability can best be achieved through restricting our risk taking on insurance and reinsurance to niches where, becauseof our expertise, we can distinguish ourselves in the underwriting and pricing process. We also believe that we can achieve attractive returns on capitalthrough the growth of our fronting business, as we carefully manage credit and collateral to generate attractive fee income, while generally utilizing lesscapital than in our highly underwritten businesses.Use Timely and Accurate Data. We design our internal processing and data collection systems to provide our management team with accurate andrelevant information in real-time. We collect premium, commission and claims data, including detailed information regarding policy price, terms, conditionsand the nature of the insured’s business. This data allows us to analyze trends in our business, including results by individual agent or broker, underwriter andclass of business and expand or contract our operations quickly in response to market conditions. We rely on our information technology systems in thisprocess. Additionally, the claims staff also contributes to our underwriting operations through its communication of claims information to our underwriters.Respond Rapidly to Market Opportunities and Challenges. We plan to grow our business to take advantage of opportunities in markets in which webelieve we can use our expertise to generate consistent underwriting profits. We seek to measure rates monthly and react quickly to changes in the rates orterms the market will accept. For the year ended December 31, 2018, our Excess and Surplus Lines segment gross written premiums increased by 23.8% overthe same period in 2017. In this favorable pricing environment, we have taken steps to grow and are increasing gross written premiums across mostunderwriting divisions in this segment. In 2018, our growth was focused in our Commercial Auto, General Casualty, Excess Casualty, Allied Health, Energy,Life Sciences, Small Business, Environmental, and Excess Property divisions within our Excess and Surplus Lines segment. During the same period, we feltrates and terms and conditions were generally less adequate for risks submitted to our Manufacturers & Contractors, Professional Liability, and MedicalProfessionals divisions, and we reduced our writings in those divisions. This very specific evaluation of each risk or class of risks is a hallmark of ourunderwriting.When market conditions have been challenging, or when actual experience has not been as favorable as we anticipated, we have tried to act quickly toevaluate our situation and to make course corrections in order to protect our profits and preserve tangible equity. Our actions have included reducing ourwritings when margins tightened and exiting lines or classes of business when we believed the risk of continuing in a line outweighed the potential rewardsfrom underwriting. We do not hesitate to increase loss estimates when we determine that it is appropriate.Manage Capital Actively. We seek to make “both sides” of our balance sheet generate better than average risk-adjusted returns. We invest and manageour capital with a goal of consistently increasing tangible equity for our shareholders and generating attractive returns on tangible equity. We intend toexpand our premium volume and capital base to take advantage of opportunities to earn an underwriting profit or to reduce our premium volume and capitalbase if attractive underwriting opportunities are not available. We expect to finance our future operations with a combination of debt and equity and do notintend to raise or retain more capital than we believe we can profitably deploy in a reasonable time frame. We may not, however, always be able to raisecapital when needed. We declared dividends to our shareholders of $36.3 million ($1.20 per share) during 2018, $50.7 million ($1.70 per share including a$0.50 per share special dividend) in 2017 and $66.3 million ($2.25 per share including a $1.35 per share special dividend) in 2016. While we have declared aspecial dividend in the past, we continue to find what we believe are attractive opportunities to earn a compelling return on our capital in the businesses thatwe target and therefore did not declare a special dividend in 2018. Our ratings from A.M. Best are very important to us, as are our relationships with ourregulators, and maintaining them in good order is a principal consideration in our decisions regarding capital management.8TABLE OF CONTENTSOur StructureThe chart below displays our corporate structure as of December 31, 2018 as it pertains to our holding and operating subsidiaries.Business SegmentsExcess and Surplus Lines SegmentWe report our U.S.-based E&S lines of business in our Excess and Surplus Lines segment. We underwrite non-admitted business through our subsidiaries,James River Insurance Company and James River Casualty Company, from offices in Richmond, Virginia; Scottsdale, Arizona; and Atlanta, Georgia. JamesRiver Insurance is our largest subsidiary as measured by gross written premiums (56.3% of consolidated gross written premiums for the year endedDecember 31, 2018 came from our Excess and Surplus Lines segment) and has been engaged in E&S insurance for 16 years. James River Insurance has had aconsistent record of underwriting profits since its second year of operation. We added James River Casualty in 2009 to give us the ability to write E&S risksin Ohio.E&S lines insurance focuses on insureds that generally cannot purchase insurance from standard lines insurers typically due to perceived risk related totheir businesses. Our Excess and Surplus Lines segment underwrites property-casualty insurance on an E&S lines basis in all states and the District ofColumbia. Our Excess and Surplus Lines segment distributes its policies through a network of authorized independent wholesale brokers throughout theUnited States. In 2018, our Excess and Surplus Lines segment’s gross written premiums grew by 23.8% over 2017 through the growth of our commercial autodivision (with a focus on transportation network companies), as well as across a number of other divisions. The Excess and Surplus Lines segment producedan average combined ratio of 86.7% from 2010 through 2018.Companies that underwrite on an E&S lines basis operate under a different regulatory structure than standard market carriers. E&S lines carriers aregenerally permitted to craft the terms of the insurance contract to suit the particular risk they are assuming. Also, E&S lines carriers are, for the most part, freeof rate regulation. In contrast, standard market carriers are generally required to use approved insurance forms and to charge rates that have been authorizedby or filed with state insurance departments. However, as E&S carriers, our insurance subsidiaries in the Excess and Surplus Lines segment are not backed byany state’s guarantee fund, and in most states these subsidiaries may only write coverage for an insured after they have been denied coverage by the standardmarket and signed declarations stating that the insured is aware that it will not have access to any state guarantee funds should these subsidiaries be unable tosatisfy their obligations.Our Excess and Surplus Lines segment writes policies for a wide range of businesses and does not write personal lines insurance. Applications forinsurance are presented to us by authorized wholesale brokers who are typically engaged by retail agents after their clients have been rejected by standardmarkets.In late 2017, the Excess and Surplus Lines segment started a binding contract unit (as part of our Small Business underwriting division) where limitedauthority for underwriting is delegated to a select group of agents on a limited number of General Liability classes through a company designed onlineportal.9TABLE OF CONTENTSAll claims for business written by the Excess and Surplus Lines segment are managed by its internal claims department although we use independentadjusters for inspection and payment of certain claims.The chart below identifies the Excess and Surplus Lines segment’s divisions and sets forth the amount of gross written premiums by each division.

Typically, we provide between $1.0 million and $10.0 million per occurrence limits above a $1.0 million attachment point. Of this amount, we retainup to $1.0 million of exposure per occurrence and cede the balance to our reinsurers. We write excess liability coverage above our own primary policies, aswell as policies issued by third parties. When we write above others’ policies, we are selective regarding underlying carriers, focusing on the nature of thebusiness, the financial strength of the carrier, their pricing and their claims handling capabilities. The underwriter who heads this division has 35 years ofindustry experience.General Casualty writes primary liability coverage on businesses exposed to premises liability type claims including real estate, mercantile and retailoperations, apartments and condominiums, daycare facilities, hotels and motels, restaurants, bars, taverns and schools.

The underwriter responsiblefor this unit has 25 years of experience in the business. Approximately 89% of the premiums written by our Allied Health division from inception through2018 have been written on a claims made and reported form. We believe this policy form significantly reduces our long-term exposure in this complicatedclass of business.Excess Property writes property risks providing limits in various layers above the primary coverage layer for a variety of classes, including apartments,condominiums, resorts, shopping centers, offices and general commercial properties. Typical per risk limits offered range from $5.0 million to $30.0 millionon a gross basis, and a maximum of $5.0 million on a net of reinsurance basis.

These brokers procure policies for their clients from us as well as from otherinsurance companies. At December 31, 2018, the segment had authorized 117 broker groups to work with us. The Excess and Surplus Lines segmentgenerally makes broker authorizations by brokerage office and underwriting division. With the exception of one hired and non-owned auto program(combined premiums of approximately $8.0 million for 2018) the Excess and Surplus Lines segment does not grant its brokers underwriting or claimsauthority. In late 2017, we introduced a Binding Contract division where limited authority for underwriting is delegated to a select group of agents for alimited group of General Liability classes through a company designed online portal.Our Excess and Surplus Lines segment selects its brokers based upon management’s review of the experience, knowledge and business plan of eachbroker. While many of our Excess and Surplus Lines segment’s brokers have more than one office, we evaluate each office as if it were a separate entity.Often, our Excess and Surplus Lines segment authorizes some but not all offices owned by a brokerage for specialized lines of business. Brokers must be ableto demonstrate an ability to competently produce both the quality and quantity of business that we seek. Brokers unable to produce consistently profitablebusiness, or who produce unacceptably low volumes of business, may be terminated. Our Excess and Surplus Lines segment’s underwriters regularly visitwith brokers in their offices to discuss the products that we offer and the needs of the brokers. We believe the personal relationships we foster with individualbrokers and our ability to respond to a wide variety of risks placed by these brokers make us an important market for them.Our Excess and Surplus Lines segment’s two largest brokers produced $439.7 million of gross written premiums for the year ended December 31, 2018,representing approximately 67.0% of the Excess and Surplus Lines segment’s gross written premiums for 2018. The two largest brokers produced $358.3million (BB&T Insurance Services represented 30.7% of consolidated gross written premiums) and $81.4 million of gross written premiums for the year endedDecember 31, 2018, respectively. One insured (Rasier LLC and its affiliates) produced $294.3 million of gross written premiums (representing 25.2% of ourconsolidated gross written premiums) and $13.9 million of fee income for the year ended December 31, 2018.In 2018 and 2017, our Excess and Surplus Lines segment paid an average commission to producers of 9.6% and 10.9%, respectively, of gross writtenpremiums.UnderwritingOur Excess and Surplus Lines segment’s staff includes over 165 individuals directly employed in underwriting policies as of December 31, 2018. We arevery selective about the policies we bind. Our Excess and Surplus Lines segment binds approximately 3% of new submissions and one out of every six newquotes. We realize all excess and surplus lines applications12TABLE OF CONTENTShave already been rejected by the standard market. If our underwriters cannot reasonably expect to bind coverage at the combination of premiums andcoverage that meet our standards, they are encouraged to quickly move on to another prospective opportunity. For the year ended December 31, 2018, wereceived approximately 222,000 submissions (new and renewal, excluding commercial auto policies), quoted over 51,000 policies and bound over 15,000policies.When we accept risk in our Excess and Surplus Lines segment, we are careful to establish terms that are suited to the risk and the pricing. As an excessand surplus lines writer, we use our freedom of rate and form to make it possible to take on risks that have already been rejected by admitted carriers who havedetermined they cannot insure these risks on approved forms at filed rates.We attempt to craft policies that offer affordable protection to our insureds by tailoring coverage in ways that make potential losses more predictable andare intended to reduce claims costs. For example, we frequently use a “punitive damages exclusion” and “defense inside the limits” endorsements, intendedto prevent excessive defense costs; “assault and battery” exclusions or sub limits that are less than the full policy limits which allows us to quantify and limitour losses more precisely than in policies without the exclusion; and “classification limitation” and “specified location” endorsements that limit coverage toknown exposures and locations. We have no material exposure to asbestos, lead paint, silica, mold, or nuclear, biological, or chemical terrorism.We design our internal processing and data collection systems to provide our management team with accurate and relevant information in real-time. Wecollect premium, commission and claims data, including detailed information regarding policy price, terms, conditions and the nature of the insured’sbusiness. This data allows us to analyze trends in our business, including results by individual broker, underwriter and class of business and expand orcontract our operations quickly in response to market conditions. We rely on our information technology systems in this process. Additionally, the claimsstaff also contributes to our underwriting operations through its communication of claims information to our underwriters.ClaimsWe believe that effective management of claims settlement and any associated litigation avoids delays and associated additional costs.Our Excess and Surplus Lines segment’s claims department consists of over 330 claims professionals as of December 31, 2018 with significant claimsexperience in the property-casualty industry.Our excess and surplus lines business generally results in claims from premises/operations liability, professional liability, hired and non-owned autoliability, auto physical damage, first party property losses and products liability. We believe the key to effective claims management is timely and thoroughclaims investigation. We seek to complete all investigations and adjust reserves appropriately as soon as is practicable after the receipt of a claim. We seek tomanage the number of claims per adjuster to allow adjusters sufficient time to investigate and resolve claims. Senior management reviews each case above aspecified amount at least quarterly to evaluate whether the key issues in the case are being considered and to monitor case reserve levels. We keep thesettlement authority of front-line adjusters low to ensure the practice of having two or more members of the department participate in the decision as towhether to settle or defend. In addition, cases with unusual damage, liability or policy interpretation issues are subjected to peer reviews. Members of theunderwriting staff participate in this process. Prior to any scheduled mediation or trial involving a claim, claims personnel conduct further peer review tomake sure all issues and exposures have been adequately analyzed.Our claims staff also contributes to our underwriting operations through communication of claims information to our underwriters. The Senior VicePresident and Chief Claims Officer heads our forms committee, which reviews and develops all policy forms and exclusions, and is also a member of theunderwriting review committee.Approximately 95% of all claims received are closed within five years in the Excess and Surplus Lines segment.13TABLE OF CONTENTSThe calendar year net loss ratios for the Excess and Surplus Lines segment for the last ten years were:200962.6%201054.9%201148.5%201252.6%201340.4%201455.2%201554.5%201662.6%201780.2%201878.8%The 2018 and 2017 calendar year loss ratios for the Excess and Surplus Lines segment were impacted by adverse reserve development of $20.7 million and$38.7 million, respectively, in the commercial auto line of business. The adverse development was primarily related to the 2016 contract year with oneinsured.Specialty Admitted Insurance SegmentThe Falls Lake Insurance Companies (“Falls Lake”) comprise our other U.S. insurance segment, Specialty Admitted Insurance. Falls Lake consists ofFalls Lake National Insurance Company (an Ohio domiciled company, licensed in 48 states and the District of Columbia and registered as a surplus linescompany in California), and its subsidiaries Stonewood Insurance Company (a North Carolina domiciled company) and Falls Lake Fire and CasualtyCompany (a California domiciled company). The Specialty Admitted Insurance segment produced 32.1% of consolidated gross written premiums for the yearended December 31, 2018.Our plan is to continue to use our broad licensure and significant management expertise to earn substantial fee income as well as underwriting profits.The Specialty Admitted Insurance segment consists of:•Individual risk workers’ compensation business, underwritten by our staff and generated by appointed agents in North Carolina, Tennessee, Virginia,South Carolina, Georgia, New Jersey, Missouri, Kansas, Pennsylvania, Massachusetts, Rhode Island, Alabama, Connecticut and Mississippi, produce14.8% of 2018 gross written premiums in this segment, (13.9% in 2017, 21.7% in 2016, 39.5% in 2015 and 50.7% in 2014); and•Fronting and program business written through selected MGAs, insurance carriers, and other producers which represented 85.2% of 2018 grosswritten premiums in this segment, (86.1% in 2017, 78.3% in 2016, 60.5% in 2015 and 49.3% in 2014).Traditional Workers’ Compensation BusinessOur individual risk workers’ compensation business, produced through a distribution channel comprised of appointed independent retail agents and alimited number of appointed wholesale brokers, remains a regionally focused effort in select Southeastern and Eastern U.S. states. For the year endedDecember 31, 2018, approximately 49% of our retail produced workers’ compensation direct written premiums were in North Carolina, 16% were in Virginia,13% were in South Carolina, and 11% were in Georgia. Building trades represented approximately 28% of the direct premiums in force in our retail producedworkers’ compensation book in 2018. Other significant industry groups include healthcare employees (16%), goods and services (15%), manufacturing(11%), specialty transportation (11%) and agriculture (6%). We view our retail produced workers’ compensation business as a core competency and seek tomake consistent underwriting profits from it. We recognize the cyclical nature of this line and are prepared to contract the business rapidly when ratesdecline, or the regulatory or economic environment makes it difficult to contain costs.Fronting & Program BusinessIn our fronting business we issue insurance policies for another insurance company which may not have the licensure, product suite or rating to serve itsdesired market, or for a program supported by reinsurance or alternative capital provider(s). We generally retain 10% or less of the underwriting risk in ourfronting business. The issuance of our policy makes us contractually responsible to the insured in the event they experience a covered loss. We enter intothese arrangements selectively with counterparties which have significant experience and market presence in their desired segment of property-casualty,workers compensation or automobile business. Underwriting, claims and financial performance is subject to regular review by our staff, and we holdappropriate collateral to manage counterparty credit risk. We specifically grant limited authority for underwriting and claims administration and employ arigorous review process to ensure the authority is14TABLE OF CONTENTSappropriately used within the terms of our contract, and that collateral held by us is appropriate as determined by our personnel. We charge fees as apercentage of gross written premiums for issuing these policies. We establish fronting opportunities through a variety of sources, including direct carrierrelationships, MGAs and reinsurance brokers.Due to our broad licensure and product filings, we are positioned to support this business on a broad basis throughout the U.S. Because of the limitedcapital allocation required to support it, we believe the fronting business represents an efficient use of capital, and we continued to expand this business in2018. One fronting program (Atlas General Insurance Services) produced $201.7 million of gross written premiums in 2018 representing 17.3% ofconsolidated gross written premiums and 53.9% of the Specialty Admitted Insurance segment's gross written premiums.Our objective over time is to utilize the combination of fee income and underwriting profits from our Specialty Admitted Insurance segment to leverageour capital and enhance returns on tangible equity. Additionally, we expect that this fee income, which was $14.8 million in 2018 and $11.3 million in 2017,will be increasingly material in future periods and provide us with a steady revenue stream.In a program arrangement, we give selected MGAs authority to act on our behalf to produce, underwrite and administer policies that meet our strictunderwriting and pricing guidelines. We enter into these arrangements selectively with agents who have significant experience and market presence inspecialty classes of property-casualty and automobile risks. Underwriting, claims and financial performance is subject to regular review by our staff. We onlywork with MGAs who permit us to actively engage with them through a combination of onsite and offsite resources to facilitate our real-time supervision oftheir work. We specifically grant limited authority for underwriting and claims administration and employ a rigorous review process to ensure the authority isappropriately used.We focus our coverage on casualty risks in our program business, although some property insurance is written. We seek to limit our risk generallythrough reinsurance either on a proportional or excess of loss basis, or sometimes both. For initial claims oversight and administration, we generallyoutsource frequency layer claims management to third-party administrators for the first $50,000 of a claim, and then provide supervisory control above thisamount.Under the terms of these program agreements, we pay fixed commissions with a profit contingency. In addition, we typically build in a “margin” betweenthe commission we earn from our reinsurers and the commissions paid to the MGAs. This spread enhances our net underwriting returns and profitability. Ourprogram business is distributed primarily through MGAs and program managers.Excluding our Atlas program, we have seven active fronting arrangements as of December 31, 2018. During 2018, these arrangements represented 25.6%of the segment’s gross written premium.Casualty Reinsurance SegmentWe report our business of writing reinsurance for third party insurance companies in our Casualty Reinsurance segment (representing 11.6% ofconsolidated gross written premiums for the year ended December 31, 2018). We participate in the reinsurance business through our Bermuda domiciledreinsurance subsidiary, JRG Re, which is a Class 3B reinsurer. JRG Re provides proportional and working layer treaty reinsurance to third parties and,through December 31, 2017, also to our U.S.-based insurance subsidiaries. For purposes of management evaluation, this segment’s underwriting results onlyinclude premiums ceded by, and losses incurred with respect to, business assumed from unaffiliated companies and does not include premiums and lossesceded under the internal reinsurance arrangements. In response to the Tax Act, we made changes to our structure in 2018 that included the formation ofCarolina Re, a Bermuda-domiciled, wholly-owned subsidiary of James River Group, Inc. Carolina Re is a Class 3A reinsurer and made an irrevocable electionto be taxed as a U.S. domestic corporation under Section 953(d) of the Code effective January 1, 2018. We generally discontinued ceding 70% of our U.S.-written premiums to JRG Re and instead ceded 70% of our U.S.-written premiums to Carolina Re as of January 1, 2018. Carolina Re also entered into a stoploss reinsurance agreement with JRG Re.During the year ended December 31, 2018, our Casualty Reinsurance segment had underwriting income of $5.1 million as a stand-alone entity. Weunderwrote $135.9 million in gross written premiums for the year ended December 31, 2018, 97.3% of which consisted of E&S risks. Of those third-partypremiums written by JRG Re, 85.8% was for general liability and 8.4% was for non-medical professional liability, with the balance primarily related to excesscasualty and commercial auto coverages. We typically structure our reinsurance treaties as quota share arrangements with loss and risk mitigating featuresthat align our interest with that of the ceding companies. On a premium volume basis, treaties with loss mitigation features including sliding scale cedingcommissions represented 81.7% of the third-party gross written premiums during 2018 and treaties written as “proportional” arrangements represented 96.9%.We purchase very little retrocessional coverage in this segment. Almost all of the segment’s premiums are for casualty lines of business. The CasualtyReinsurance segment writes virtually no reinsurance designed to respond specifically to natural catastrophes.The Casualty Reinsurance segment’s two largest brokers generated $54.0 million and $42.3 million, respectively, representing 70.9% of the segment’sgross written premiums in the year ended December 31, 2018. The Casualty Reinsurance15TABLE OF CONTENTSsegment’s three largest relationships with unaffiliated ceding companies generated $126.3 million ($83.4 million, $22.1 million, and $20.8 million,respectively) representing 10.8% of consolidated gross written premiums and 92.9% of the Casualty Reinsurance segment's gross written premiums for theyear ended December 31, 2018.Underwriting profits and investment income earned by JRG Re are exempt from U.S. taxation. We do, however, pay a 1% U.S. Federal excise tax onpremiums ceded to JRG Re. At December 31, 2018, JRG Re cash and invested assets made up 54.9% of our total cash and invested assets.Corporate and Other SegmentOur President and Chief Executive Officer, our Chief Financial Officer and other holding company employees are part of the Corporate and Othersegment. This is where we set and direct strategy for the group as a whole as well as high level objectives for each of the three operating segments. We makeall capital management, capital allocation, treasury functions, information technology and group wide risk management decisions in this segment. Ourdecisions at this level also include reinsurance purchasing.Purchase of ReinsuranceWe routinely purchase reinsurance for our Excess and Surplus Lines and Specialty Admitted Insurance segments and, less frequently purchaseretrocessional coverage for our Casualty Reinsurance segment. The purchase of reinsurance reduces volatility by limiting our exposure to large losses andprovides capacity for growth. In a reinsurance transaction, an insurance company transfers, or cedes, all or part of its exposure in return for a portion of thepremium. In a retrocession transaction, a reinsurer transfers, or cedes, all or part of its exposure in return for a portion of the premium. Our companies remainlegally responsible for the entire obligation to policyholders and ceding companies, irrespective of any reinsurance or retrocession coverage we maypurchase. Typically, we pay claims from our own funds and then seek reimbursement from the reinsurer or retrocessionaire, as applicable. There is creditexposure with respect to losses ceded to the extent that any reinsurer or retrocessionaire is unable or unwilling to meet the obligations ceded by us underreinsurance or retrocessional treaties. The ability to collect on reinsurance or retrocessional reinsurance is subject to many factors, including the solvency ofthe counterparty and their interpretation of contract language and other factors. We currently have no disputes with any reinsurer or retrocessionaire, and weare not aware of any credit quality issues with any of our reinsurers or retrocessionaires at December 31, 2018.Purchased Property ReinsuranceOur focus on return on tangible equity leads us to avoid lines of business that we know are exposed to high degrees of volatility. The Excess and SurplusLines segment writes a limited book of excess property risks (approximately $17.0 million direct written premiums in 2018). The risks assumed in this bookare geographically dispersed and significantly reinsured to limit losses. The Excess and Surplus Lines segment may retain up to $5.0 million per risk on ourexcess property book; however, the average retained amount per risk is approximately $2.5 million. In our Specialty Admitted Insurance segment, we focuson casualty business, but we do write a limited amount of property insurance, principally through our fronting and programs business. The focus in ourCasualty Reinsurance segment is also primarily casualty business, but we do have a relatively small amount of assumed business with property exposure.In our Excess and Surplus Lines segment, we purchased a surplus share reinsurance treaty specifically designed to cover property risks. The surplus sharetreaty along with facultative reinsurance helps ensure that our net retained limit per risk will be $5.0 million or less. Additionally, we purchased catastrophereinsurance of $40.0 million in excess of a $5.0 million retention for the group that is intended to cover the 1 in 1,000 year modeled aggregate PML on thesegment’s excess property book. We buy such high limits because we believe the property catastrophe models are less accurate when applied to small booksof business like ours than when applied to larger portfolios. Where the Specialty Admitted Insurance segment incurs incidental property risks in its programbook of business, the segment has purchased coverage for $4.0 million in excess of $1.0 million per occurrence, in addition to the protection provided underthe corporate $40.0 million in excess of $5.0 million catastrophe treaty. This is also intended to cover the 1 in 1,000 year modeled aggregate PML on anyproperty exposures the Specialty Admitted Insurance segment assumes. In our Casualty Reinsurance segment, we believe that our maximum loss from acatastrophic event is approximately $2.0 million and, as a result, we do not currently purchase retrocessional reinsurance coverage for property-catastropherisks. In the aggregate, we believe our pre-tax group-wide PML from a 1 in 1,000 year catastrophic event is approximately $10.0 million, inclusive ofreinstatement premiums payable.16TABLE OF CONTENTSPurchased Casualty ReinsuranceIn our Excess and Surplus Lines segment, there are five divisions where we only write $1.0 million per occurrence limits (Commercial Auto,Manufacturers and Contractors, General Casualty, Small Business and Sports and Entertainment), and therefore, we do not purchase any specific reinsurancefor these policies. In the other divisions, where we issue policies with larger limits, we purchase reinsurance in excess of $1.0 million per occurrence.In our Specialty Admitted Insurance segment, there are two distinct reinsurance strategies. For individual risk workers' compensation, we purchase $29.4million excess of $600,000 per occurrence; and, effective October 1, 2017, we also purchased a 50% quota share coverage of the primary $600,000. For ourfronting and program business, we purchase proportional reinsurance and excess of loss reinsurance to limit our exposure to no more than $500,000 peroccurrence.For both our Excess and Surplus Lines segment and our Specialty Admitted Insurance segment, we purchase a clash and contingency reinsurance treatythat covers all casualty business for $10.0 million in excess of $2.0 million per occurrence. This coverage is intended to respond in a situation where we havemultiple insured losses from the same event.In our Casualty Reinsurance segment, we currently do not purchase any material retrocessional reinsurance. In prior periods, we have purchasedproportional and excess of loss retrocessional coverage for particular situations related to specific treaties, but have only done so on a limited basis.For 2018, our top ten reinsurers represented 79.4% of our total ceded reinsurance recoverables, and all of these reinsurance recoverables were fromreinsurers with an A.M.

All material reinsurance recoverables from these reinsurers are collateralized.​Amounts Recoverable from an Indemnifying PartyThe Company is a party to a set of insurance contracts with an insured group of companies under which the Company pays losses and loss adjustmentexpenses on the contract. The Company has indemnity agreements with this group of insured parties (non-insurance entities) and is contractually entitled toreceive reimbursement for a significant portion of the losses and loss adjustment expenses paid on behalf of the insured parties and other expenses incurredby the Company. The insured parties are required to collateralize all amounts currently due to the Company and to provide additional collateral sufficient tocover the amounts that may be recoverable under the indemnity agreements, including among other things case loss and loss adjustment expense reserves,IBNR loss and loss adjustment expense reserves, extra contractual obligations and excess of policy limits liabilities. This collateral is currently providedthrough a collateral trust arrangement established in favor of the Company by a captive insurance company affiliate of the insured group. At December 31,2018, the cash equivalent collateral held in the17TABLE OF CONTENTScollateral trust arrangement was approximately $1,099.2 million, which exceeds the amount of claims receivable and unpaid reported losses and lossadjustment expenses outstanding. The Company has ongoing exposure to estimated losses and expenses on these contracts growing at a faster pace thangrowth in our collateral balances. In addition, we have credit exposure if our estimates of future losses and loss adjustment expenses and other amountsrecoverable, which are the basis for establishing collateral balances, are lower than actual amounts paid or payable. The amount of our credit exposure in anyof these instances could be material. To mitigate these risks, we closely and frequently monitor our exposure compared to our collateral held, and we requestadditional collateral when our analysis indicates that we have uncollateralized exposure.Reserve PolicyWe seek to establish reserves that will adequately meet our obligations. We have seven credentialed actuaries on staff, and we engage independentactuarial consultants to review our decisions regarding reserves twice a year.We maintain reserves for specific claims incurred and reported, reserves for claims incurred but not reported (“IBNR”) and reserves for uncollectiblereinsurance when appropriate. Our ultimate liability may be greater or less than current reserves. In the insurance industry, there is always the risk thatreserves may prove inadequate. We continually monitor reserves using new information on reported claims and a variety of statistical techniques and adjustour estimates as necessary as experience develops or new information becomes known. Such adjustments (referred to as reserve development) are included incurrent operations. Anticipated inflation is reflected implicitly in the reserving process through analysis of cost trends and the review of historicaldevelopment. We do not discount our reserves for losses and loss adjustment expenses to reflect estimated present value.When setting our reserves, we use a blend of actuarial techniques that are chosen to reflect the nature of the lines of insurance we underwrite. We seek tobe consistent and transparent in establishing our reserves.In many cases, several years may elapse between the occurrence of an insured loss, the reporting of the loss and our eventual payment of the loss. Weestablish loss and loss adjustment expense reserves for the ultimate payment of all losses and loss adjustment expenses incurred. We estimate the reserve forlosses and loss adjustment expenses using individual case-basis valuations of reported claims. We also use statistical analyses to estimate the cost of lossesthat have been incurred but not reported to us. These estimates are based on historical information and on estimates of future trends that may affect thefrequency of claims and changes in the average cost of claims that may arise in the future. We also consider various factors such as:•Loss emergence and insured reporting patterns;​•Underlying policy terms and conditions;​•Business and exposure mix;​•Trends in claim frequency and severity;​•Changes in operations;​•Emerging economic and social trends;​•Inflation;​•Changes in the regulatory and litigation environments; and​•Discussions with third-party actuarial consultants.​The procedures we use to estimate loss reserves assume that past experience, adjusted for the effects of current developments and anticipated trends, is anappropriate basis for predicting future events. It also assumes that adequate historical or other data exists upon which to make these judgments. Theseestimates are by their nature subjective and imprecise, and ultimate losses and loss adjustment expenses may vary from established reserves.Our Reserve Committee consists of our Chief Actuary, Chief Executive Officer, Chief Financial Officer, and Chief Accounting Officer. Additionally, thepresidents and chief actuaries of each of our three insurance segments assist in the evaluation of reserves in their respective segments. The Reserve Committeemeets quarterly to review the actuarial recommendations made by each chief actuary and uses its best judgment to determine the best estimate to be recordedfor the reserve for losses and loss adjustment expenses on our quarterly balance sheet.18TABLE OF CONTENTSThe following table reflects our reserve development by segment during the calendar years 2018 to 2009 individually and in aggregate.Segment Excess andSurplus Lines SpecialtyAdmittedInsuranceCasualtyReinsuranceGrand TotalCalendar Year 2018 $(15,012)(1) $5,560 $(8,220) $(17,672)2017 (20,023)(2) 2,721 (4,170) (21,472)2016 24,079(3) 3,822(4,185)23,7162015 25,424(4) 3,531(12,637)16,3182014 27,283(5) 5,854(5,719)27,4182013 40,734(6) 1,410(4,692)37,4522012 20,122(7) (4,898)(16,617)(8) (1,393)2011 21,034 1,712(2,835)19,9112010 10,922 (381)(857)9,6842009 3,193 1,591(1,067)3,717Cumulative Development $137,756 $20,922$(60,999)$97,679(1)Includes $20.7 million of adverse development in the commercial auto line of business that was primarily related to the 2016 contract year with oneinsured, partially offset by $5.7 million of favorable development from other divisions.​(2)Includes $38.7 million of adverse development in the commercial auto line of business that was primarily related to the 2016 contract year with oneinsured, partially offset by $18.6 million of favorable development from other divisions primarily from the 2014 through 2016 accident years.​(3)Includes $10.0 million of favorable development from the 2015 accident year, $10.7 million from the 2014 accident year and $4.5 million from the 2013accident year.​(4)Includes $17.3 million and $10.5 million of favorable development from the 2014 and 2013 accident year, respectively.​(5)Includes $7.9 million of favorable development from the 2011 accident year, $4.2 million from the 2007 accident year and $5.0 million from the 2009accident year.(6)Includes $11.8 million of favorable development from the 2009 accident year, $7.3 million of favorable development from the 2007 accident year and$5.8 million of favorable development from the 2008 accident year.(7)Includes $8.0 million of favorable development from the 2009 accident year, $4.3 million of favorable development from the 2008 accident year and$4.1 million of favorable development from the 2007 accident year.(8)Includes $9.0 million of adverse development on assumed crop business almost entirely from the 2011 accident year and $7.6 million of adversedevelopment on other assumed business.Among the indicators of reserve strength that we monitor closely are the number of claims outstanding from a given year and the amount of IBNRreserves held on our balance sheet for claims that have been incurred but not yet reported to us. As a general rule, every known claim has a specific casereserve established against it which management believes is adequate to resolve the claim and pay attendant expenses based on information available at thetime.A significant portion of reported claims from prior policy years were closed at December 31, 2018. The table below sets forth the percentage of claimsclosed by policy year for our Excess and Surplus Lines and Specialty Admitted Insurance segments for the policy years indicated.19TABLE OF CONTENTSPercentage of Claims Closed at December 31, 2018Policy Year Excess andSurplus LinesSegment ExcludingCommercialAuto Excess andSurplus LinesSegmentCommercialAutoSpecialtyAdmittedInsuranceSegmentIndividualRisk Workers’CompSpecialtyAdmittedInsuranceSegmentFrontingandPrograms2004 99.9% —99.8%—2005 99.8% —100.0%—2006 99.6% —100.0%—2007 99.3% —100.0%—2008 99.2% —99.8%—2009 99.0% —99.9%—2010 98.4% —99.9%—2011 97.4% —99.7%—2012 95.6% —99.8%—2013 95.0% 99.4%100.0%98.8%2014 89.8% 98.9%99.9%98.2%2015 86.2% 99.7%99.1%95.4%2016 80.6% 97.6% 94.8% 87.8%2017 74.5% 95.1% 77.3% 74.7%Another indicator of reserve strength that we monitor closely is the percentage of our gross and net loss reserves that are comprised of IBNR reserves.

While we are willing to make investments in non-traditional types of investments, we avoid risks that we do notunderstand well, as well as structures or situations we think could cause20TABLE OF CONTENTSsubstantial loss of capital. The vast majority of our investment portfolio is managed by third party, independent investment managers.The majority of our investment portfolio is invested in what we refer to as our Core Portfolio of investment grade fixed income securities. This portfolioprovides predictable income with low risk of principal loss. We seek to augment the return on the Core Portfolio by investing in bank loans, higher yieldingsecurities and private investments. We designed these strategies to improve our investment return and are focused on opportunistic investing in areas wherewe believe our management, directors or employees have expertise or understanding of the risk and return of the investment.Our strategy is designed to earn higher returns than an investment grade fixed income approach alone while maintaining a high average portfolio creditrating and investing in asset classes and allocations that are consistent with the insurance regulatory and rating agency framework within which we operate.We generally focus on securities that provide some current income.As a result of affiliated and third party reinsurance contracts, we have been able to grow our asset base at JRG Reinsurance Company Ltd, which isdomiciled in Bermuda and is not subject to U.S. corporate taxation. At December 31, 2018, 54.9% of our cash and invested assets were held at JRG Re.The prolonged low interest rate environment made it difficult for insurance companies to earn attractive returns on capital because of reducedinvestment income. If sustained, recent increases in interest rates will slowly improve investment income from fixed income investments. Our premiumgrowth has allowed us to build our asset base. Cash and invested assets now represent 3.8 times our tangible equity.A summary of our investment portfolio at December 31, 2018 is as follows: December 31, 2018Portfolio Book Value Market Value Carrying Value Book Yield % of CarryingValue ($ in thousands)Core $1,243,616 $1,226,946 $1,226,946 2.96% 71.0%Bank Loans 299,086 288,740 299,014 6.97% 17.3%Incremental Yield 124,838 127,606 127,606 6.46% 7.4%Private Investments 73,571 NA 4.3%Total 1,727,137 100.0%Less cash and cash equivalents in Core andBank Loans (49,291) Total Invested Assets $1,677,846 We have generally managed our overall portfolio to a duration of 3 to 5 years. At December 31, 2018, the average duration of our investment portfoliowas 3.4 years.Core PortfolioThe Core Portfolio consists of cash and investment grade fixed income securities. Our objective in the Core Portfolio is to earn attractive risk-adjustedreturns with a low risk of loss of principal. We use a third-party manager to manage the Core Portfolio.Bank LoansThe Bank Loan portfolio primarily consists of investments in participations in syndicated bank loans, but may also include a small allocation of bonds.Bank loans in our portfolio are generally senior secured loans with an average credit quality of “B” as of December 31, 2018 and floating interest rates basedon spreads over LIBOR. We believe bank loans are an attractive asset class because (1) floating-rate loans help to reduce our risk of loss in the event of risinginterest rates, (2) the loans are generally senior secured, (3) the asset class has a history of relatively high recovery rates in the event of default, (4) theportfolio provides an attractive yield and (5) the maturities of the loans are relatively short (average of 5 years). We invest in this asset class by owningindividual loan participations that are carried at amortized cost less any loan loss allowance. We have over nine years of experience in investing in this assetclass through a third-party manager.Incremental Yield PortfolioThe Incremental Yield Portfolio consists of investments in low investment grade and below investment grade bonds, preferred stocks, dividend payingcommon equities and exchange traded funds. The average credit quality of the fixed income securities in this portfolio as of December 31, 2018 is BBB. Wegenerally invest in fixed income securities where we believe21TABLE OF CONTENTSthat risk of default is low relative to the potential yield on the securities. We own preferred stocks, generally in the financial services industry. In someinstances, we will purchase common equity securities and exchange traded funds. However, these purchases are generally used as an effective means to getaccess to a high yielding asset class. As of December 31, 2018, only $9.5 million of the Incremental Yield Portfolio is invested in common equities andexchange traded funds.Private Investment PortfolioWe make selective investments in private debt or equity securities in areas where we see significant opportunity or attractive risk and returncharacteristics. We focus on investments where we believe we have an understanding of the risk and opportunity and have the ability to monitor themclosely. At December 31, 2018, we held 11 private investments with a total carrying value of $73.6 million. Our portfolio consists of investments in wind andsolar energy, banking, small cap equities, loans of middle market private equity sponsored companies, equity tranches of collateralized loan obligations(CLOs), and tranches of distressed home loans. We are opportunistic in our private investment strategy and our portfolio may grow or shrink based on theopportunities available to us. Despite being only 4.3% of our portfolio, we believe our Private Investment Portfolio has added meaningful returns to ourtangible equity. Our Private Investment strategy has significant risk and not all investments are successful. As a result, we intentionally keep this portfolio asa small portion of the overall investment portfolio.Our recent total returns on our portfolio are as follows: 2016 2017 2018 Trailing 3 yearsEnded 2018Core 2.34% 3.09% 0.73% 2.05%Bank Loans 14.09% 6.56% 3.82% 8.07%Incremental 9.23% 10.86% 0.42% 6.74%Total 5.18% 4.49% 1.32% 3.65%Total returns are calculated as the realized or unrealized gain or loss of an asset plus interest and dividends paid while the asset is held.We consider a portion of our investment portfolio to be invested in non-traditional investments. We consider non-traditional investments to includeinvestments that are (1) not rated bond or fixed income securities (2) non-listed equities or (3) investments that generally have less liquidity than rated bondor fixed income securities or listed equities. Non-traditional investments held at December 31, 2018 and their respective percentage of our total investedassets at such date consist of syndicated bank loans (15.6%), interests in limited liability companies that invest in renewable energy opportunities (1.8%),limited partnerships that invest in debt or equity securities (1.7%), notes receivable for renewable energy projects (0.5%), and a private debt security (0.3%).We will continue to actively review opportunities to invest in non-traditional assets and may invest in additional non-traditional assets in the future.Our invested assets totaled $1,677.8 million as of December 31, 2018. The weighted average credit rating of our portfolio of fixed maturity securities,bank loans and redeemable preferred stocks as of December 31, 2018 was “A”. We have intentionally maintained a cautious interest rate risk position byhaving an average duration of 3.4 years at December 31, 2018. This compares to an average duration at December 31, 2017 of 3.5 years. Based on the currentduration of 3.4 years, a 1.0% increase in interest rates would result in a pre-tax decline in the market value of our portfolio of approximately $55.1 million.Insurance Cycle Management and GrowthThe insurance and reinsurance business is cyclical in nature, with “hard” and “soft” cycles. Hard markets occur when insurance underwriters limit theirexposure in a line of business or across their entire portfolio. When underwriters exercise restraint, insurance buyers are forced to pay more to induceunderwriters to cover their risks. A hard market can also be created by economic expansions when capital committed to backing insurance policies does notgrow as fast as the demand for insurance. There is generally a correlation between interest rates and the willingness of insurance companies to commit theircapital to writing insurance. When fixed income yields are low, insurance companies need to raise insurance prices to improve underwriting results in order tooffset loss of investment income.We are currently in a growth phase for our U.S. primary operations. In both our Excess and Surplus Lines and Specialty Admitted Insurance segments, weare experiencing growth in premiums driven by stable rates as well as increases in policy count and exposures. The table below shows the changes in grosswritten premiums we have experienced in our operating segments from 2016 through 2018.22TABLE OF CONTENTS 2018 2017 2016Gross Written Premiums $% Change $% Change $ % Change ($ in thousands)Excess and Surplus Lines $656,53823.8 % $530,12042.9% $370,84420.1%Specialty Admitted Insurance 374,34618.3 % 316,43073.7% 182,221100.3%Casualty Reinsurance 135,889(42.3)% 235,35527.7% 184,3336.9%Total $1,166,7737.8 % $1,081,90546.7% $737,39828.9%In years prior to those presented, the business written at our U.S. primary operations has, at times, been subject to “soft” market conditions, reflected bothin price decreases and reduced underlying exposures. The recession in the United States from 2008 to 2010 was a significant driver of these soft marketconditions.Our Excess and Surplus Lines segment is the most sensitive to hard and soft markets. We have, therefore, sought to diversify this business by geography,line of business and revenue stream. From 2006 to 2010, we reduced the gross written premiums in this business from $249.1 million to $116.1 million, or53.4%. While we have been growing this business and achieving increasing or stable rates for several periods through December 31, 2018, there will likely beperiods in the future where our growth moderates, stagnates or turns negative.The Excess and Surplus Lines segment has historically been able to make an underwriting profit regardless of the state of the underwriting cycle. Thissegment's weighted average combined ratio for 2010 through 2018 is 86.7%.Traditionally, admitted insurance lines have been very susceptible to market cycles. We believe this trend is continuing. We seek to isolate ourselvesfrom these trends in our Specialty Admitted Insurance segment by writing lines of business we believe are slightly less competitive, by prudently purchasingreinsurance and by being willing to dramatically reduce our writings when market conditions warrant.A material portion of the profitability we seek to achieve from our fronting business will come from fee income that is generated via policies that areissued by our insurance companies and then mostly or wholly reinsured to third parties. Because we earn substantial fees from underwriting business onwhich we retain little or no insurance risk, this business can be profitable to us even in soft market conditions. We have $319.1 million of gross writtenpremiums for fronting and program business for 2018 ($30.5 million on a net basis), and we expect our fee income will continue to grow in future periods andprovide us with a steady revenue stream that will be relatively insulated from conditions in the admitted insurance market.In the Casualty Reinsurance segment, we have the ability to manage the cycle by growing or shrinking our business according to market conditions andthe corresponding prices and terms being offered for the assumption of specific risks. We have a small team of nine people in Bermuda who underwrite andadminister the business written by JRG Re in Bermuda. Accordingly, our overhead is low and does not necessitate us growing this business from its currentsize.CompetitionWe compete in a variety of markets against a variety of competitors depending on the nature of the risk and coverage being underwritten. Thecompetition for any one account may range from large international firms to smaller regional companies in the domiciles in which we operate. To remaincompetitive, our strategy includes, among other measures: (1) focusing on rate adequacy and underwriting discipline, (2) leveraging our distribution network,(3) controlling expenses, (4) maintaining financial strength and issuer credit ratings and (5) providing quality services to agents and policyholders.Excess and Surplus LinesCompetition within the E&S lines marketplace comes from a wide range of carriers. In addition to mature E&S companies that operate nationwide, thereis competition from carriers formed in recent years. The Excess and Surplus Lines segment may also compete with national and regional carriers from thestandard market willing to underwrite selected accounts on an admitted basis. Competitors in this segment include ACE Westchester Specialty Group,Admiral Insurance Company (W. R. Berkley Corporation), AmRisc Insurance Company (BB&T - Branch Banking & Trust Company), Apollo Syndicate,Arrowhead General Insurance Agency, Inc., Axis Insurance Company (Axis Capital Holdings Limited), Beazley Group (Lloyd’s), Brit Insurance (Lloyd’s),Colony Specialty Insurance Company (Argo Group International Holdings, Ltd.), Evanston Insurance Company (Markel Corporation), First MercuryInsurance Company (Fairfax Financial Holdings, Ltd.), Gemini Insurance Company (W.

Starr & Company), United Specialty Insurance Company, Ventus RiskManagement (utilizing XL Catlin23TABLE OF CONTENTSInsurance Company paper - hedge fund and private investors for capital), and other large national and multi-national insurance carriers.Specialty Admitted InsuranceDue to the diverse nature of the products offered by the Specialty Admitted Insurance segment, competition comes from various sources. The majority ofthe competition for our workers’ compensation business comes from regional companies or regional subsidiaries of national carriers in the domiciles in whichthey operate. National carriers tend to compete for fronting and program accounts along all product lines. Competitors in our workers’ compensation businessinclude Builders Mutual Insurance Company, Accident Fund Insurance Company of America, W. R. Berkley Corporation, American Interstate InsuranceCompany (AMERISAFE, Inc.), and Amtrust Group.

The BMA, in deciding whether to grant registration, has broad discretion to act as it thinks fit in the public interest. TheBMA is required by the Insurance Act to determine whether the applicant is a fit and proper body to be engaged in the insurance business and, in particular,whether it has, or has available to it, adequate knowledge and expertise. The registration of an applicant as an insurer is subject to its complying with theterms of its registration and such other conditions as the BMA may impose at any time.It is not necessary that the insurance company be incorporated in Bermuda. A foreign corporation may obtain a permit under the Companies Act ofBermuda, 1981 (the “Companies Act”) to carry on business in Bermuda and then be registered as an insurer in Bermuda under the Insurance Act.The Insurance Act does not distinguish between insurers and reinsurers; companies are registered (licensed) under the Insurance Act as “insurers”(although in certain circumstances a condition to registration may be imposed to the effect that the company may carry on only reinsurance business). TheInsurance Act uses the defined term “insurance business” to include reinsurance business.The Insurance Act also grants to the BMA powers to supervise, investigate and intervene in the affairs of insurance companies.An Insurance Advisory Committee appointed by the Bermuda Minister of Finance advises the BMA on matters connected with the discharge of theBMA’s functions and subcommittees thereof supervise, investigate and review the law and practice of insurance in Bermuda, including reviews of accountingand administrative procedures.The Insurance Act imposes solvency and liquidity standards on Bermuda insurance companies, as well as auditing and reporting requirements.Certain significant aspects of the Bermuda insurance regulatory framework applicable to Class 3A insurers and/or Class 3B insurers are set forth below.Classification of InsurersThe Insurance Act distinguishes between insurers carrying on long-term business, insurers carrying on general business and insurers carrying on specialpurpose business. There are six classifications of insurers carrying on general business, ranging from Class 1 insurers (pure captives) to Class 4 insurers (largecommercial underwriters). Carolina Re is licensed as a Class 3A insurer and JRG Re is licensed as a Class 3B insurer and each is regulated as such under theInsurance Act.Minimum Paid-Up Share CapitalA Class 3A insurer and a Class 3B insurer are each required to maintain fully paid up share capital of at least $120,000.24TABLE OF CONTENTSPrincipal Representative and Principal OfficeA Class 3A insurer and a Class 3B insurer are each required to maintain a principal office and to appoint and maintain a principal representative inBermuda. For the purposes of the Insurance Act, the principal office of Carolina Re and JRG Re is located at Wellesley House, 2nd Floor, 90 Pitts Bay Road,Pembroke, HM 08, Bermuda. Carolina Re’s and JRG Re’s principal representative is Helen Gillis, the Chief Financial Officer of JRG Re.Without a reason acceptable to the BMA, an insurer may not terminate the appointment of its principal representative, and the principal representativemay not cease to act as such, unless 30 days’ prior notice in writing to the BMA is given of the intention to do so.It is the duty of the principal representative to forthwith notify the BMA where the principal representative reaches the view that there is a likelihood ofthe insurer (for which the principal representative acts) becoming insolvent, or on it coming to the knowledge of the principal representative, or the principalrepresentative has reasonable grounds for believing, that a reportable “event” has occurred. Examples of a reportable “event” include a failure by the insurerto comply substantially with a condition imposed upon it by the BMA relating to a solvency margin or a liquidity or other ratio, a significant loss reasonablylikely to cause the insurer to fail to comply with its enhanced capital requirement (discussed below) and the occurrence of a material change (as such term isdefined under the Insurance Act) in its business operations.Within 14 days of such notification to the BMA, the principal representative must furnish the BMA with a written report setting out all the particulars ofthe case that are available to the principal representative.Where there has been a significant loss which is reasonably likely to cause the insurer to fail to comply with its enhanced capital requirement, theprincipal representative must also furnish the BMA with a capital and solvency return reflecting an enhanced capital requirement prepared using post-lossdata. The principal representative must provide this within 45 days of notifying the BMA regarding the loss.Furthermore, where a notification has been made to the BMA regarding a material change, the principal representative has 30 days from the date of suchnotification to furnish the BMA with unaudited interim statutory financial statements in relation to such period as the BMA may require, together with ageneral business solvency certificate in respect of those statements.Head OfficeA Class 3A insurer and a Class 3B insurer shall each maintain its head office in Bermuda. In determining whether the insurer satisfies this requirement,the BMA shall consider, inter alia, the following factors: (i) where the underwriting, risk management and operational decision making of the insurer occurs;(ii) whether the presence of senior executives who are responsible for, and involved in, the decision making related to the insurance business of the insurer arelocated in Bermuda; and (iii) where meetings of the board of directors of the insurer occur. In making its determination, the BMA may also have regard to (a)the location where management of the insurer meets to effect policy decisions of the insurer; (b) the residence of the officers, insurance managers oremployees of the insurer; and (c) the residence of one or more directors of the insurer in Bermuda. This provision does not apply to an insurer that has apermit to conduct business in Bermuda under the Companies Act or the Non-Resident Insurance Undertakings Act 1967.Loss Reserve SpecialistA Class 3A insurer and a Class 3B insurer are each required to appoint an individual approved by the BMA to be its loss reserve specialist. In order toqualify as an approved loss reserve specialist, the applicant must be an individual qualified to provide an opinion in accordance with the requirements of theInsurance Act and the BMA must be satisfied that the individual is fit and proper to hold such an appointment.A Class 3A insurer and a Class 3B insurer are each required to submit annually an opinion of its approved loss reserve specialist with its capital andsolvency return in respect of its total general business insurance technical provisions (i.e. the aggregate of its net premium provisions, net loss and lossexpense provisions and risk margin, as each is reported in the insurer’s statutory economic balance sheet). The loss reserve specialist’s opinion must state,among other things, whether or not the aggregate amount of technical provisions shown in the statutory economic balance sheet as at the end of the relevantfinancial year (i) meets the requirements of the Insurance Act and (ii) makes reasonable provision for the total technical provisions of the insurer under theterms of its insurance contracts and agreements.Annual Financial StatementsA Class 3A insurer and Class 3B insurer are each required to prepare and submit to the BMA, on an annual basis, audited financial statements whichhave been prepared under generally accepted accounting principles or international financial reporting standards (“GAAP financial statements”) and auditedstatutory financial statements.The Insurance Act prescribes rules for the preparation and substance of statutory financial statements (which include, in statutory form, a balance sheet,an income statement, a statement of capital and surplus and notes thereto). The statutory25TABLE OF CONTENTSfinancial statements include detailed information and analysis regarding premiums, claims, reinsurance and investments of the insurer.The insurer’s annual GAAP financial statements, and the auditor’s report thereon, and the statutory financial statements are required to be filed with theBMA within four months from the end of the relevant financial year (unless specifically extended with the approval of the BMA). The statutory financialstatements do not form a part of the public records maintained by the BMA but the GAAP financial statements are available for public inspection.Declaration of ComplianceAt the time of filing its statutory financial statements, a Class 3A insurer and a Class 3B insurer are each also required to deliver to the BMA a declarationof compliance, in such form and with such content as may be prescribed by the BMA, declaring whether or not the insurer has, with respect to the precedingfinancial year (i) complied with all requirements of the minimum criteria applicable to it, (ii) complied with the minimum margin of solvency as at itsfinancial year end, (iii) complied with the applicable enhanced capital requirements as at its financial year end, (iv) complied with applicable conditions,directions and restrictions imposed on, or approvals granted to, the insurer and (v) complied with the minimum liquidity ratio for general business as at itsfinancial year end. The declaration of compliance is required to be signed by two directors of the insurer, and if the insurer has failed to comply with any ofthe requirements referenced in (i) through (v) above or observe any limitations, restrictions or conditions imposed upon the issuance of its license, ifapplicable, the insurer will be required to provide the BMA with particulars of such failure in writing. A Class 3A insurer and a Class 3B insurer shall beliable to a civil penalty by way of a fine for failure to comply with a duty imposed on it in connection with the delivery of the declaration of compliance.Annual Statutory Financial Return and Annual Capital and Solvency ReturnA Class 3A insurer and a Class 3B insurer are each required to file with the BMA a statutory financial return no later than four months after its financialyear end (unless specifically extended with the approval of the BMA).The statutory financial return of an insurer shall consist of (i) an insurer information sheet, (ii) an auditor’s report, (iii) the statutory financial statementsand (iv) notes to the statutory financial statements.The insurer information sheet shall state, among other matters, (i) whether the general purpose financial statements of the insurer for the relevant yearhave been audited and an unqualified opinion issued, (ii) the minimum margin of solvency applying to the insurer and whether such margin was met,(iii) whether or not the minimum liquidity ratio applying to the insurer for the relevant year was met and (iv) whether or not the insurer has complied withevery condition attached to its certificate of registration. The insurer information sheet shall state if any of the questions identified in items (ii), (iii) or (iv)above is answered in the negative, whether or not the insurer has taken corrective action in any case and, where the insurer has taken such action, describe theaction in an attached statement.The directors are required to certify whether the minimum solvency margin has been met, and the independent approved auditor is required to statewhether in its opinion it was reasonable for the directors to make this certification.Where an insurer’s accounts have been audited for any purpose other than compliance with the Insurance Act, a statement to that effect must be filedwith the statutory financial return.In addition, each year the insurer is required to file with the BMA a capital and solvency return along with its annual statutory financial return. Theprescribed form of capital and solvency return comprises the insurer’s Bermuda Solvency Capital Requirement (“BSCR”) model or an approved internalcapital model in lieu thereof, together with such schedules as prescribed by the Insurance (Prudential Standards) (Class 3A Solvency Requirement) Rules2011 for Class 3A insurers and the Insurance (Prudential Standards) (Class 4 and 3B Solvency Requirement) Rules 2008 for Class 3B insurers, respectively, aseach are amended from time to time.Neither the statutory financial return nor the capital and solvency return is available for public inspection.Quarterly Financial ReturnA Class 3B insurer, not otherwise subject to group supervision, is required to prepare and file quarterly financial returns with the BMA on or before thelast day of the months of May, August and November of each year. The quarterly financial returns consist of (i) quarterly unaudited financial statements foreach financial quarter (which must minimally include a balance sheet and income statement and must also be recent and not reflect a financial position thatexceeds two months), (ii) a list and details of material intra-group transactions that the Class 3B insurer is a party to and the Class 3B insurer’s riskconcentrations that have materialized since the most recent quarterly or annual financial returns, details surrounding all intra-group reinsurance andretrocession arrangements and other intra-group risk transfer insurance business arrangements that have materialized since the most recent quarterly or annualfinancial returns and (iii) details of the ten largest exposures to26TABLE OF CONTENTSunaffiliated counterparties and any other unaffiliated counterparty exposures exceeding 10% of the Class 3B insurer’s statutory capital and surplus.Public DisclosuresPursuant to recent amendments to the Insurance Act, all commercial insurers and insurance groups are required to prepare and file with the BMA, andalso publish on their web site, a financial condition report. The BMA has discretion to approve modifications and exemptions to the public disclosure ruleson application by the insurer if, among other things, the BMA is satisfied that the disclosure of certain information will result in a competitive disadvantageor compromise confidentiality obligations of the insurer.Independent Approved AuditorA Class 3A insurer and a Class 3B insurer must each appoint an independent auditor who will audit and report on the insurer’s GAAP financialstatements and statutory financial statements, each of which are required to be filed annually with the BMA. The auditor must be approved by the BMA asthe independent auditor of the insurer. If the insurer fails to appoint an approved auditor or at any time fails to fill a vacancy for such auditor, the BMA mayappoint an approved auditor for the insurer and shall fix the remuneration to be paid to the approved auditor within 14 days, if not agreed sooner by theinsurer and the auditor.Non-insurance BusinessNo Class 3A insurer or Class 3B insurer may engage in non-insurance business unless that non-insurance business is ancillary to its core business. Non-insurance business means any business other than insurance business and includes carrying on investment business, managing an investment fund asoperator, carrying on business as a fund administrator, carrying on banking business, underwriting debt or securities or otherwise engaging in investmentbanking, engaging in commercial or industrial activities and carrying on the business of management, sales or leasing of real property.Minimum Liquidity RatioThe Insurance Act provides a minimum liquidity ratio for general business insurers. A Class 3A insurer and a Class 3B insurer engaged in generalbusiness is required to maintain the value of its relevant assets at not less than 75% of the amount of its relevant liabilities. Relevant assets include cash andtime deposits, quoted investments, unquoted bonds and debentures, first liens on real estate, investment income due and accrued, accounts and premiumsreceivable, reinsurance balances receivable, funds held by ceding reinsurers and any other assets which the BMA, on application in any particular case madeto it with reasons, accepts in that case.There are certain categories of assets which, unless specifically permitted by the BMA, do not automatically qualify as relevant assets, such as unquotedequity securities, investments in and advances to affiliates and real estate and collateral loans.The relevant liabilities are total general business insurance reserves and total other liabilities less deferred income taxes and letters of credit, guaranteesand other instruments.Minimum Solvency Margin and Enhanced Capital RequirementsThe Insurance Act provides that the value of the statutory assets of an insurer must exceed the value of its statutory liabilities by an amount greater thanits prescribed minimum solvency margin (“MSM”).The MSM that must be maintained by a Class 3A insurer and a Class 3B insurer with respect to its general business is the greater of (i) $1,000,000, (ii)20% of the first $6,000,000 of net premiums written (but if the net premiums written are in excess of $6,000,000, the figure is $1,200,000 plus 15% of netpremiums written in excess of $6,000,000) or (iii) 15% of the aggregate of net loss and loss expense provisions and other insurance reserves or (iv) 25% of theECR (as defined below) as reported at the end of the relevant year.Class 3A insurers and Class 3B insurers are also required to maintain available statutory economic capital and surplus at a level equal to or in excess ofits enhanced capital requirement (“ECR”) which is established by reference to either the BSCR model or an approved internal capital model.The BSCR model is a risk-based capital model which provides a method for determining an insurer’s capital requirements (statutory economic capitaland surplus) by taking into account the risk characteristics of different aspects of the insurer’s business. The BSCR formula establishes capital requirementsfor ten categories of risk: fixed income investment risk, equity investment risk, interest rate/liquidity risk, currency risk, concentration risk, premium risk,reserve risk, credit risk, catastrophe risk and operational risk. For each category, the capital requirement is determined by applying factors to asset, premium,reserve, creditor, probable maximum loss and operation items, with higher factors applied to items with greater underlying risk and lower factors for less riskyitems.27TABLE OF CONTENTSWhile not specifically referred to in the Insurance Act (or required thereunder), the BMA has also established a target capital level (“TCL”) for each Class3A insurer and Class 3B insurer equal to 120% of its ECR. The TCL serves as an early warning tool for the BMA, and failure to maintain statutory capital atleast equal to the TCL will likely result in increased regulatory oversight.Any insurer which at any time fails to meet its MSM requirements must, upon becoming aware of such failure, immediately notify the BMA and, within14 days thereafter, file a written report with the BMA containing particulars of the circumstances that gave rise to the failure and setting out its plan detailingspecific actions to be taken and the expected timeframe in which the insurer intends to rectify the failure.Any insurer which at any time fails to meet its applicable enhanced capital requirement shall, upon becoming aware of that failure or of having reason tobelieve that such a failure has occurred, immediately notify the BMA in writing and within 14 days of such notification file with the BMA a written reportcontaining particulars of the circumstances leading to the failure, and a plan detailing the manner, specific actions to be taken and time within which theinsurer intends to rectify the failure, and within 45 days of becoming aware of that failure or of having reason to believe that such a failure has occurred,furnish the BMA with (i) unaudited statutory economic balance sheets and unaudited interim statutory financial statements prepared in accordance withGAAP covering such period as the BMA may require; (ii) the opinion of a loss reserve specialist in relation to the total general business insurance technicalprovisions as set out in the economic balance sheet, where applicable; (iii) a general business solvency certificate in respect of the financial statements; and(iv) a capital and solvency return reflecting an enhanced capital requirement prepared using post failure data where applicable.Eligible CapitalTo enable the BMA to better assess the quality of an insurer’s capital resources, a Class 3A insurer and a Class 3B insurer are each required to disclose themakeup of its capital in accordance with the recently introduced “3-tiered eligible capital system”. Under this system, all of the insurer’s capital instrumentswill be classified as either basic or ancillary capital which in turn will be classified into one of three tiers based on their “loss absorbency” characteristics.Highest quality capital will be classified Tier 1 Capital, and lesser quality capital will be classified as either Tier 2 Capital or Tier 3 Capital. Under thisregime, up to certain specified percentages of Tier 1, Tier 2 and Tier 3 Capital may be used to support the insurer’s MSM, ECR and TCL.The characteristics of the capital instruments that must be satisfied to qualify as Tier 1, Tier 2 and Tier 3 Capital are set out in the Insurance (EligibleCapital) Rules 2012, and amendments thereto. Under these rules, Tier 1, Tier 2 and Tier 3 Capital may, until January 1, 2026, include capital instruments thatdo not satisfy the requirement that the instrument be non-redeemable or settled only with the issuance of an instrument of equal or higher quality upon abreach, or if it would cause a breach, of the ECR.Where the BMA has previously approved the use of certain instruments for capital purposes, the BMA’s consent will need to be obtained if suchinstruments are to remain eligible for use in satisfying the MSM and the ECR.Code of ConductThe Insurance Code of Conduct (the “Insurance Code”) prescribes the duties, standards, procedures and sound business principles that must be compliedwith by all insurers registered under the Insurance Act. The BMA will assess an insurer’s compliance with the Insurance Code in a proportional mannerrelative to the nature, scale and complexity of its business. Failure to comply with the requirements of the Insurance Code will be taken into account by theBMA in determining whether an insurer is conducting its business in a sound and prudent manner as prescribed by the Insurance Act, may result in the BMAexercising its powers of intervention and investigation (see below) and will be a factor in calculating the operational risk charge under the insurer’s BSCR orapproved internal model.Restrictions on Dividends and DistributionsA Class 3A insurer and a Class 3B insurer are each prohibited from declaring or paying a dividend if it is in breach of its MSM, ECR or minimumliquidity ratio or if the declaration or payment of such dividend would cause such a breach. Where an insurer fails to meet its MSM or minimum liquidityratio on the last day of any financial year, it will be prohibited from declaring or paying any dividends during the next financial year without the approval ofthe BMA.In addition, a Class 3A insurer and a Class 3B insurer is prohibited from declaring or paying in any financial year dividends of more than 25% of its totalstatutory capital and surplus (as shown on its previous financial year’s statutory balance sheet), unless it files (at least seven days before payment of suchdividends) with the BMA an affidavit signed by at least two directors (one of whom must be a Bermuda resident director if any of the insurer’s directors areresident in Bermuda) and the principal representative stating that it will continue to meet its solvency margin and minimum liquidity ratio. Where such anaffidavit is filed, it shall be available for public inspection at the offices of the BMA.28TABLE OF CONTENTSReduction of CapitalNo Class 3A insurer or Class 3B insurer may reduce its total statutory capital by 15% or more, as set out in its previous year’s financial statements, unlessit has received the prior approval of the BMA. Total statutory capital consists of the insurer’s paid in share capital, its contributed surplus (sometimes calledadditional paid in capital) and any other fixed capital designated by the BMA as statutory capital (such as letters of credit).A Class 3A insurer or Class 3B insurer seeking to reduce its respective statutory capital by 15% or more, as set out in its previous year’s financialstatements, is also required to submit an affidavit signed by at least two directors (one of whom must be a Bermuda-resident director if any of the insurer’sdirectors are resident in Bermuda) and the principal representative stating that the proposed reduction will not cause it to fail its relevant margins and suchother information as the BMA may require. Where such an affidavit is filed, it shall be available for public inspection at the offices of the BMA.Policyholder PriorityOn July 30, 2018, the Insurance Amendment (No. 2) Act 2018 amended the Insurance Act to provide for the prior payment of policyholders’ liabilitiesahead of general unsecured creditors in the event of the liquidation or winding up of an insurer. The amendments provide inter alia that, subject to the priorpayment of preferential debts under the Employment Act 2000 and the Companies Act, the insurance debts of an insurer must be paid in priority to all otherunsecured debts of the insurer. Insurance debt is defined as a debt to which an insurer is or may become liable pursuant to an insurance contract, excludingdebts owed to an insurer under an insurance contract where the insurer is the person insured. Insurance contract is defined as any contract of insurance, capitalredemption contract or a contract that has been recorded as insurance business in the financial statements of the insurer pursuant to the Insurance Accounts1981 or the Insurance Account Rules 2016, as applicable. The provisions became effective on January 1, 2019.Fit and Proper ControllerThe BMA maintains supervision over the controllers of all registered insurers in Bermuda.A controller includes (i) the managing director of the registered insurer or its parent company, (ii) the chief executive of the registered insurer or of itsparent company, (iii) a shareholder controller, and (iv) any person in accordance with whose directions or instructions the directors of the registered insurer orof its parent company are accustomed to act.The definition of shareholder controller is set out in the Insurance Act, but generally refers to (i) a person who holds 10% or more of the shares carryingrights to vote at a shareholders’ meeting of the registered insurer or its parent company, (ii) a person who is entitled to exercise 10% or more of the votingpower at any shareholders’ meeting of such registered insurer or its parent company, or (iii) a person who is able to exercise significant influence over themanagement of the registered insurer or its parent company by virtue of its shareholding or its entitlement to exercise, or control the exercise of, the votingpower at any shareholders’ meeting.A shareholder controller that owns 10% or more, but less than 20% of the shares as described above is defined as a 10% shareholder controller. Ashareholder controller that owns 20% or more, but less than 33% of the shares as described above is defined as a 20% shareholder controller. A shareholdercontroller that owns 33% or more but less than 50% of the shares as described above is defined as a 33% shareholder controller. A shareholder controller thatowns 50% or more of the shares as described above is defined as a 50% shareholder controller.As the shares of Carolina Re’s and JRG Re’s parent company are traded on a recognized stock exchange, a person who becomes a 10%, 20%, 33% or50% shareholder controller of the insurer, shall, within 45 days, notify the BMA in writing that he or she has become such a controller. In addition, a personwho is a shareholder controller of Carolina Re or JRG Re must serve on the BMA a notice in writing that he or she has reduced or disposed of his or herholding in the insurer where the proportion of voting rights in the insurer held by him or her will have reached or has fallen below 10%, 20%, 33% or 50% asthe case may be, not later than 45 days after such disposal.Any person who contravenes the Insurance Act by failing to give notice or knowingly becomes a controller of any description before the required 45days has elapsed is guilty of an offence and liable to a fine of $25,000 on summary conviction.The BMA may file a notice of objection to any person who has become a controller of any description where it appears that such person is not or is nolonger, a fit and proper person to be a controller of the registered insurer. Before issuing a notice of objection, the BMA is required to serve upon the personconcerned a preliminary written notice stating the BMA’s intention to issue formal notice of objection. Upon receipt of the preliminary written notice, theperson served may, within 28 days, file written representations with the BMA, which shall be taken into account by the BMA in making their finaldetermination. Any person who continues to be a controller of any description after having received a notice of objection shall be guilty of an29TABLE OF CONTENTSoffense and shall be liable on summary conviction to a fine of $25,000 (and a continuing fine of $500 per day for each day that the offense is continuing) or,if convicted on indictment, to a fine of $100,000 and/or two years in prison.Notification by Registered Person of Change of Controllers and OfficersAll registered insurers are required to give written notice to the BMA of the fact that a person has become, or ceased to be, a controller or officer of theinsurer within 45 days of becoming aware of such fact. An officer in relation to a registered insurer means a director, chief executive or senior executiveperforming duties of underwriting, actuarial, risk management, compliance, internal audit, finance or investment matters.Notification of Material ChangesAll registered insurers are required to give notice to the BMA of their intention to effect a material change within the meaning of the Insurance Act. Forthe purposes of the Insurance Act, the following changes are material: (i) the transfer or acquisition of insurance business being part of a scheme falling underSection 25 of the Insurance Act or Section 99 of the Companies Act, (ii) the amalgamation with or acquisition of another firm, (iii) engaging in unrelatedbusiness that is retail business, (iv) the acquisition of a controlling interest in an undertaking that is engaged in non-insurance business which offers servicesand products to persons who are not affiliates of the insurer, (v) outsourcing all or substantially all of the company’s actuarial, risk management complianceor internal audit functions, (vi) outsourcing all or a material part of an insurer’s underwriting activity, (vii) the transfer other than by way of reinsurance of allor substantially all of a line of business, (viii) expansion into a material new line of business, (ix) the sale of an insurer, and (x) outsourcing of an officer role.No registered insurer shall take any steps to give effect to a material change unless it has first served notice on the BMA that it intends to effect suchmaterial change, and before the end of 30 days, either the BMA has notified such company in writing that it has no objection to such change or that periodhas lapsed without the BMA having issued a notice of objection.Before issuing a notice of objection, the BMA is required to serve upon the person concerned a preliminary written notice stating the BMA’s intention toissue a formal notice of objection. Upon receipt of the preliminary written notice, the person served may, within 28 days, file written representations with theBMA which shall be taken into account by the BMA in making their final determination.Group SupervisionThe BMA may, in respect of an insurance group, determine whether it is appropriate for it to act as its group supervisor. An insurance group is defined asa group of companies that conducts insurance business. The BMA may make such determination where it ascertains that (i) the group is headed by a“specified insurer” (that is to say, it is headed by either a Class 3A, Class 3B or Class 4 general business insurer or a Class C, Class D or Class E long terminsurer or another class of insurer designated by order of the BMA); or (ii) where the insurance group is not headed by a “specified insurer”, where it is headedby a parent company which is incorporated in Bermuda or (iii) where the parent company of the group is not a Bermuda company, in circumstances where theBMA is satisfied that the insurance group is directed and managed from Bermuda or the insurer with the largest balance sheet total is a specified insurer.Where the BMA determines that it should act as the group supervisor, it shall designate a specified insurer that is a member of the insurance group to bethe designated insurer (the “Designated Insurer”) and it shall give to the Designated Insurer and other applicable insurance regulatory authority written noticeof its intention to act as group supervisor. Before the BMA makes a final determination whether or not to act as group supervisor, it shall take into accountany written representations made by the Designated Insurer submitted within such period as is specified in the notice.The BMA may exclude any company that is a member of an insurance group from group supervision on the application of the Designated Insurer, or onits own initiative, provided the BMA is satisfied that (i) the company is situated in a country or territory where there are legal impediments to cooperationand exchange of information, (ii) the financial operations of the company have a negligible impact on insurance group operations or (iii) the inclusion of thecompany would be inappropriate with respect to the objectives of group supervision.The BMA may, on its own initiative or on the application of the relevant Designated Insurer, include within group supervision a company that is amember of the group that is not on the Register of Group Particulars (described below) if it is satisfied the financial operations of the company in questionmay have a material impact on the insurance group’s operations and its inclusion would be appropriate having regard to the objectives of group supervision.Once the BMA has been designated as group supervisor, the Designated Insurer must ensure that the insurance group of which it is a member appoints (i)an individual approved by the BMA who is qualified as a group actuary to provide an opinion on the insurance group’s insurance technical provisions inaccordance with the requirements of Schedule XIV “Group Statutory Economic Balance Sheet” of the Insurance (Prudential Standards) (Insurance GroupSolvency Requirement) Rules 2011 and (ii) an auditor approved by the BMA to audit the financial statements of the group.30TABLE OF CONTENTSPursuant to its powers under the Insurance Act, the BMA will maintain a register of particulars for every insurance group (the “Register of GroupParticulars”) for which it acts as the group supervisor, detailing the names and addresses of (i) the Designated Insurer; (ii) each member company of theinsurance group falling within the scope of group supervision; (iii) the principal representative of the insurance group in Bermuda; (iv) other competentauthorities supervising other member companies of the insurance group; and (v) the insurance group auditors. The Designated Insurer must immediatelynotify the BMA of any changes to the above details entered on the Register of Group Particulars.As group supervisor, the BMA will perform a number of supervisory functions including (i) coordinating the gathering and dissemination of relevant oressential information for going concerns and emergency situations, including the dissemination of information which is of importance for the supervisorytask of other competent authorities; (ii) carrying out supervisory reviews and assessments of the insurance group; (iii) carrying out assessments of theinsurance group’s compliance with the rules on solvency, risk concentration, intra-group transactions and good governance procedures; (iv) planning andcoordinating through regular meetings held at least annually (or by other appropriate means) with other competent authorities, supervisory activities inrespect of the insurance group, both as a going concern and in emergency situations; (v) coordinating enforcement actions that may need to be taken againstthe insurance group or any of its members; and (vi) planning and coordinating meetings of colleges of supervisors in order to facilitate the carrying out of thefunctions described above.The BMA may, for the purposes of group supervision, make rules applying to Designated Insurers which take into account any activities of the insurancegroup of which they are members or of other members of the insurance group. Such rules may make provision for the assessment of the financial situation ofthe insurance group; the solvency position of the insurance group (including the imposition of prudential standards in relation to enhanced capitalrequirements, capital and solvency returns, insurance reserves and eligible capital that must be complied with by the Designated Insurers); the system ofgovernance and risk management of the insurance group; intra-group transactions and risk concentrations; and supervisory reporting and disclosure inrespect of the insurance group.Supervision, Investigation, Intervention and DisclosureThe BMA may, by notice in writing served on a registered person or a designated insurer, require the registered person or designated insurer to providesuch information and/or documentation as the BMA may reasonably require with respect to matters that are likely to be material to the performance of itssupervisory functions under the Insurance Act. In addition, it may require such person’s auditor, underwriter, accountant or any other person with relevantprofessional skill of such registered person or designated insurer to prepare a report on any aspect pertaining thereto. In the case of a report, the person soappointed shall immediately give the BMA written notice of any fact or matter of which he becomes aware or which indicates to him that any conditionattaching to his registration under the Insurance Act is not or has not, or may not be or may not have, been fulfilled and that such matters are likely to bematerial to the performance of its functions under the Insurance Act. If it appears to the BMA to be desirable in the interests of the clients of a registeredperson or relevant insurance group, the BMA may also exercise these powers in relation to subsidiaries, parent companies and other affiliates of the registeredperson or designated insurer.If the BMA deems it necessary to protect the interests of the policyholders or potential policyholders of an insurer or insurance group, it may appointone or more competent persons to investigate and report on the nature, conduct or state of the insurer’s or the insurance group’s business, or any aspectthereof, or the ownership or control of the insurer or insurance group. If the person so appointed thinks it necessary for the purposes of the investigation, suchperson may also investigate the business of any person who is or has been, at any relevant time, a member of the insurance group or of a partnership of whichthe person being investigated is a member. In this regard, it shall be the duty of every person who is or was a controller, officer, employee, agent, banker,auditor, accountant, barrister and attorney or insurance manager to produce to the person appointed such documentation as the appointed person mayreasonably require for purposes of the investigation, and to attend and answer questions relevant to the investigation and to otherwise provide suchassistance as may be necessary in connection therewith.Where the BMA suspects that a person has failed to properly register under the Insurance Act or that a registered person or designated insurer has failedto comply with a requirement of the Insurance Act or that a person is not, or is no longer, a fit and proper person to perform functions in relation to a regulatedactivity, it may, by notice in writing, carry out an investigation into such person (or any other person connected thereto). In connection therewith, the BMAmay require every person who is or was a controller, officer, employee, agent, banker, auditor, accountant, barrister and attorney or insurance manager tomake a report and produce such documents in his care, custody and control and to attend before the BMA to answer questions relevant to the BMA’sinvestigation and to take such actions as the BMA may direct. The BMA may also enter any premises for the purposes of carrying out its investigation andmay petition the court for a warrant if it believes a person has failed to comply with a notice served on him, there are reasonable grounds for suspecting theinformation or documentation produced in response to such notice is incomplete, or that its directions will not be complied with or that any relevantdocuments would be removed, tampered with or destroyed.31TABLE OF CONTENTSIf it appears to the BMA that the business of the registered insurer is being conducted in a way that there is a significant risk of the insurer becominginsolvent or being unable to meet its obligations to policyholders, or that the insurer is in breach of the Insurance Act or any conditions imposed upon itsregistration, or the minimum criteria stipulated in the Insurance Act is not or has not been fulfilled in respect of a registered insurer, or that a person hasbecome a controller without providing the BMA with the appropriate notice or in contravention of a notice of objection, or the registered insurer is in breachof its ECR, or that a designated insurer is in breach of any provision of the Insurance Act or the regulations or rules applicable to it, the BMA may issue suchdirections as it deems desirable for safeguarding the interests of policyholders or potential policyholders of the insurer or the insurance group. The BMA may,among other things, direct an insurer, for itself and in its capacity as designated insurer of the insurance group of which it is a member, (i) not to take on anynew insurance business, (ii) not to vary any insurance contract if the effect would be to increase the insurer’s liabilities, (iii) not to make certain investments,(iv) to realize certain investments, (v) to maintain in or transfer to the custody of a specified bank, certain assets, (vi) not to declare or pay any dividends orother distributions or to restrict the making of such payments, (vii) to limit its premium income, (viii) not to enter into specified transactions with anyspecified person or persons of a specified class, (ix) to provide such written particulars relating to the financial circumstances of the insurer as the BMA thinksfit, (x) as an individual insurer only, and not in its capacity as designated insurer, to obtain the opinion of a loss reserve specialist and submit it to the BMA,and/or (xi) to remove a controller or officer.The BMA has the power to assist other regulatory authorities, including foreign insurance regulatory authorities, with their investigations involvinginsurance and reinsurance companies in Bermuda if it is satisfied that the assistance being requested is in connection with the discharge of regulatoryresponsibilities and that such cooperation is in the public interest. The grounds for disclosure by the BMA to a foreign regulatory authority without consentof the insurer are limited and the Insurance Act provides for sanctions for breach of the statutory duty of confidentiality.Cancellation of Insurer’s RegistrationAn insurer’s registration may be cancelled by the BMA at the request of the insurer or on certain grounds specified in the Insurance Act. Failure by theinsurer to comply with its obligations under the Insurance Act, or if the BMA believes that the insurer has not been carrying on business in accordance withsound insurance principles, would be examples of such grounds.Certain Other Bermuda Law ConsiderationsCorporate Bermuda Law ConsiderationsAlthough James River Group Holdings, Ltd. is incorporated in Bermuda, it is designated as a non-resident for Bermuda exchange control purposes bythe BMA. Pursuant to its non-resident status, James River Group Holdings, Ltd. may engage in transactions in currencies other than the Bermuda dollar, andthere are no restrictions on its ability to transfer funds (other than funds denominated in Bermuda dollars) in and out of Bermuda or to pay dividends to non-residents who are holders of its common shares in currencies other than the Bermuda dollar.In accordance with Bermuda law, share certificates are issued only in the names of companies, partnerships or individuals. In the case of an applicantacting in a special capacity (for example, as an executor or trustee), certificates may, at the request of the applicant, record the capacity in which the applicantis acting. Notwithstanding the recording of any such special capacity, we are not bound to investigate or see to the execution of any such trust. We will takeno notice of any trust applicable to any of our common shares whether or not we have notice of such trust.Each of James River Group Holdings, Ltd., Carolina Re and JRG Re is incorporated in Bermuda as an “exempted company.” Under Bermuda law,exempted companies are companies formed for the purpose of conducting business outside Bermuda from a principal place of business in Bermuda. As aresult, they are exempt from Bermuda laws restricting the percentage of share capital that may be held by non-Bermudians. However, exempted companiesmay not participate in certain business transactions, including: (i) the acquisition or holding of land in Bermuda except that required for their business andheld by way of lease or tenancy for a term not exceeding 50 years or, with the consent of the Minister of Finance granted in his discretion by way of lease ortenancy for a term not exceeding 21 years in order to provide accommodation or recreational facilities for its officers and employees, (ii) the taking ofmortgages on land in Bermuda to secure an amount in excess of B.D.$50,000 without the consent of the Minister of Finance, (iii) the acquisition of anybonds or debentures secured by any land in Bermuda, other than certain types of Bermuda government securities or securities issued by Bermuda publicauthorities, or (iv) the carrying on of business of any kind in Bermuda, except in furtherance of business carried on outside Bermuda or under license grantedby the Minister of Finance . Generally, it is not permitted without a special license granted by the Minister of Finance to insure Bermuda domestic risks orrisks of persons of, in or based in Bermuda. Each of Carolina Re and JRG Re is a licensed insurer in Bermuda, and so it may carry on activities from Bermudathat are related to and in support of its insurance business.Each of James River Group Holdings, Ltd., Carolina Re and JRG Re must comply with the provisions of the Companies Act regulating the payment ofdividends and making distributions from contributed surplus. A company may not declare or pay32TABLE OF CONTENTSa dividend, or make a distribution out of contributed surplus, if there are reasonable grounds for believing that (i) it is, or would after the payment be, unableto pay its liabilities as they become due, or (ii) the realizable value of the assets would thereby be less than its liabilities. In addition, certain provisions of theInsurance Act will limit our ability to pay dividends.Under the Companies Act, where a Bermuda company issues shares at a premium (that is, for a price above the par value), whether for cash or otherwise, asum equal to the aggregate amount or value of the premium on those shares must be transferred to an account called “the share premium account.” Theprovisions of the Companies Act relating to the reduction of the share capital of a company apply as if the share premium account were paid up share capitalof that company, except for certain matters such as: (i) paying up unissued shares to be issued to members as fully paid bonus shares, (ii) writing off thepreliminary expenses of the company or the expenses of, or the commission paid or discount allowed on any issue of shares or debentures of the company, or(iii) providing for the premiums payable on redemption of shares or of any debentures of the company. The paid up share capital may not be reduced if, onthe date the reduction is to be effected, there are reasonable grounds for believing that the company is, or after the reduction would be, unable to pay itsliabilities as they become due. See “- Restrictions on Dividends and Distributions”.Securities may be offered or sold in Bermuda only in compliance with the provisions of the Investment Business Act 2003 and the Exchange Control Act1972 and related regulations of Bermuda which regulate the sale of securities in Bermuda. In addition, the permission of the BMA is required under theprovisions of the Exchange Control Act 1972 and related regulations for all issuances and transfers of shares of Bermuda companies to or from a non-residentof Bermuda for exchange control purposes, other than in cases where the BMA has granted a general permission. The BMA, in its notice to the public datedJune 1, 2005, has granted a general permission for the issue and subsequent transfer of any securities of a Bermuda company from and/or to a non-resident ofBermuda for exchange control purposes for so long as any “equity securities” of the company (which would include our common shares) are listed on an“Appointed Stock Exchange” (which would include the NASDAQ Stock Market). In granting the general permission, the BMA accepts no responsibility forour financial soundness or the correctness of any of the statements made or opinions expressed herein.We have received consent from the BMA to issue, grant, create, sell and transfer freely any of our shares, stock, bonds, notes (other than promissorynotes), debentures, debenture stock, units under a unit trust scheme, shares in an oil royalty, options, warrants, coupons, rights and depository receipts to andamong persons who are either resident or non-resident of Bermuda for exchange control purposes.Bermuda Work Permit ConsiderationsUnder Bermuda law, non-Bermudians (other than spouses of Bermudians and individuals holding permanent resident’s certificates) may not engage inany gainful occupation in Bermuda without the appropriate government standard work permit.Standard work permits can be obtained for a one-, two-, three-, four- or five-year period. Where a standard work permit is being applied for, it is arequirement that the job must be advertised for three days (within an eight-day period) in the local newspaper in addition to the Bermuda Government JobBoard. Should no Bermudian (or spouse of a Bermudian or holder of a permanent resident’s certificate) meet the minimum standards as stipulated in theadvertisements, the employer may then apply for a standard work permit for the non-Bermudian. Employers must complete a Recruitment Disclosure Formand provide information, including the qualifications of all applicants. The Department of Immigration will compare the qualifications and experience of anyBermudian applicants (or spouse of a Bermudian or holder of a permanent resident’s certificate) to that stipulated in the advertisements and to the non-Bermudian to be satisfied that the role could not have been filled by a Bermudian (or spouse of a Bermudian or holder of a permanent resident’s certificate).In addition to the advertising, there are also many other documents that are required prior to the Department of Immigration making its decision.If the position for which the standard work permit is being applied is that of a Chief Executive Officer or other chief officer post, the Minister of HomeAffairs will waive the requirement to advertise the job and on occasion may waive the requirement to advertise for other senior executive positions.If an employer wishes to change an employee’s job title, provided that the job description, duties, remuneration and benefits remain unchanged, theemployer does not need to advertise or obtain the permission of the Minister of Home Affairs to do this, but it must inform the Department of Immigration andpay the necessary fee after the change has occurred.If an employer wishes to promote an employee currently on a work permit from his current job to another within the same business, the permission of theMinister of Home Affairs must first be obtained. The employer will need to provide evidence of internal recruitment efforts and consideration of internalBermudian candidates.A temporary work permit can take up to 10 working days to process and a standard work permit can take up to four weeks to process.33TABLE OF CONTENTSU.S. Insurance RegulationState RegulationOur U.S. insurance subsidiaries are subject to extensive regulation and supervision by their state of domicile, as well as those states in which they dobusiness. The purpose of such regulation and supervision is primarily to provide safeguards for policyholders, rather than to protect the interests ofshareholders. The insurance laws of the various states establish regulatory agencies with broad administrative powers, including the power to grant or revokeoperating licenses and regulate trade practices, investments, premium rates, deposits of securities, the form and content of financial statements and insurancepolicies, dividend limitations, cancellation and non-renewal of policies, accounting practices and the maintenance of specified reserves and capital for theprotection of policyholders.The payment of dividends by our subsidiaries to us is limited by statute. In general, the laws and regulations applicable to our domestic insurancesubsidiaries limit the aggregate amount of dividends or other distributions that they may declare or pay within any 12 month period without advanceregulatory approval. In Ohio, the domiciliary state of James River Insurance and Falls Lake National Insurance Company (formerly Stonewood NationalInsurance Company) (“Falls Lake National”), the limitation is the greater of statutory net income for the preceding calendar year or 10% of the statutorysurplus at the end of the preceding calendar year, provided that such dividends may only be paid out of the earned surplus of each of the companies withoutobtaining regulatory approvals. In North Carolina, the domiciliary state of Stonewood Insurance, this limitation is the greater of statutory net incomeexcluding realized capital gains for the preceding calendar year or 10% of the statutory surplus at the end of the preceding calendar year, provided that suchdividends may only be paid out of unassigned surplus without obtaining regulatory approval. In Virginia, the domiciliary state of James River CasualtyCompany, this limitation is the greater of statutory net income excluding realized capital gains of the preceding calendar year or 10% of the statutory surplusat the end of the preceding calendar year, provided that such dividends may only be paid out of unassigned surplus without obtaining regulatory approval. InCalifornia, the domiciliary state of Falls Lake Fire and Casualty Company, this limitation is the greater of statutory net income for the preceding calendaryear or 10% of the statutory surplus at the end of the preceding calendar year, provided that such dividends may only be paid out of unassigned surpluswithout obtaining regulatory approval. Moreover, as a condition to obtaining its license in California, Falls Lake Fire and Casualty Company provided acommitment to the California Department of Insurance that it would not pay any shareholder dividends for a five-year period commencing January 1, 2016.In addition, insurance regulators have broad powers to prevent reduction of statutory surplus to inadequate levels and could refuse to permit the payment ofdividends calculated under any applicable formula.Premium rate regulation varies greatly among jurisdictions and lines of insurance. In most states in which our subsidiaries write insurance, premium ratesfor the various lines of insurance are subject to either prior approval or limited review upon implementation. States require rates for property-casualtyinsurance that are adequate, not excessive, and not unfairly discriminatory.Our insurance subsidiaries are required to file quarterly and annual reports with the appropriate regulatory agency in its state of domicile and with TheNational Association of Insurance Commissioners (“NAIC”) based on applicable statutory regulations, which differ from U.S. generally accepted accountingprinciples. Their business and accounts are subject to examination by such agencies at any time.Many jurisdictions have laws and regulations that limit an insurer’s ability to withdraw from a particular market. For example, states may limit aninsurer’s ability to cancel or non-renew policies. Furthermore, certain states prohibit an insurer from withdrawing one or more lines of business from the states,except pursuant to a plan approved by the state insurance department. Laws and regulations that limit cancellation and non-renewal and that subject programwithdrawals to prior approval requirements may restrict our ability to exit unprofitable marketplaces in a timely manner.State laws governing insurance holding companies and insurance companies require an insurance holding company and their insurance subsidiaries toregister with the insurance department authority, to file certain reports disclosing information, including but not limited to capital structure, ownership,management, and financial condition. Such holding company laws also impose standards and filing requirements on certain transactions between relatedcompanies, which include, among other requirements, that all transactions be fair and reasonable, that an insurer’s surplus as regards policyholders bereasonable and adequate in relation to its liabilities and that expenses and payments be allocated to the appropriate party in accordance with customaryaccounting practices. These transactions between related companies include transfers of assets, loans, reinsurance agreements, service agreements, certaindividend payments by the insurance companies and certain other material transactions and modifications to such transactions. In 2012, the NAIC adoptedsignificant changes to the insurance holding company act and regulations (the “NAIC Amendments”). The NAIC Amendments, when adopted by the variousstates, are designed to respond to perceived gaps in the regulation of insurance holding company systems in the United States. One of the major changes is arequirement that an insurance holding company system’s ultimate controlling person submit annually to its lead state insurance regulator an “enterprise riskreport” that identifies activities, circumstances or events involving one or more affiliates of an insurer that, if not remedied properly, are likely to have amaterial adverse effect upon the financial condition or34TABLE OF CONTENTSliquidity of the insurer or its insurance holding company system as a whole. Other changes include (i) requiring a controlling person to submit prior notice toits domiciliary insurance regulator of its divestiture of control, (ii) having detailed minimum requirements for cost sharing and management agreementsbetween an insurer and its affiliates and (iii) expanding the types of agreements between an insurer and its affiliates to be filed with its domiciliary insuranceregulator. The NAIC Amendments must be adopted by a state legislature and such state’s insurance regulator in order to be effective in that state. Each ofCalifornia, North Carolina, Ohio, and Virginia, the states in which our U.S. insurance subsidiaries are domiciled, include this enterprise risk report. Inaddition, in 2012, the NAIC adopted the Risk Management and Own Risk and Solvency Assessment Model Act (the “ORSA Model Act”). The ORSA ModelAct, when adopted by the various states, will require an insurance holding company system’s Chief Risk Officer to submit at least annually to its lead stateinsurance regulator an Own Risk and Solvency Assessment Summary Report (“ORSA”). The ORSA is a confidential internal assessment, appropriate to thenature, scale and complexity of an insurer, of the material and relevant risks identified by the insurer associated with an insurer’s current business plan andthe sufficiency of capital resources to support those risks. The ORSA Model Act must be adopted by a state legislature in order to be effective in that state.Each of California, North Carolina, Ohio, and Virginia, the states in which our U.S. insurance subsidiaries are domiciled, adopted and require an ORSA filing.The insurance holding company laws and regulations of the states in which our insurance companies are domiciled also generally require that before aperson can acquire direct or indirect control of an insurer domiciled in the state, and in some cases prior to divesting its control, prior written approval mustbe obtained from the insurer’s domiciliary state insurance regulator. In addition to insurance holding company laws and regulations, under the organizationalpermit issued by the California Department of Insurance to Falls Lake Fire and Casualty Company, Falls Lake Fire and Casualty Company, as a new insurer,was required to enter into an agreement with Falls Lake National restricting the transfer of Falls Lake Fire and Casualty Company’s shares (the “AgreementRestricting Shares”) for a five-year period commencing January 1, 2016. Specifically, under the agreement, the restriction on share transfer is releasedautomatically without further approval or consent by the California Department of Insurance, or any other party, at the following respective times: 5% at theend of the first year of the 5-year restriction period; an additional 5% at the end of the second year; an additional 10% at the end of the third year; anadditional 20% at the end of the fourth year; and the remainder at the end of the fifth year. Therefore, under the organizational permit and the AgreementRestricting Shares, Falls Lake National’s ability to directly or indirectly transfer the shares of Falls Lake Fire and Casualty Company to anyone without theprior written approval of the California Department of Insurance is limited. These laws and the similar conditions applicable to Falls Lake Fire and CasualtyCompany’s shares may discourage potential acquisition proposals and may delay, deter or prevent an investment in or a change of control involving us, orone or more of our regulated subsidiaries, including transactions that our management and some or all of our shareholders might consider desirable. Pursuantto applicable laws and regulations, “control” over an insurer is generally presumed to exist if any person, directly or indirectly, owns, controls, holds thepower to vote or holds proxies representing, 10 percent or more of the voting securities of that insurer. Indirect ownership includes ownership of theCompany’s common shares.Under state insurance guaranty fund laws, insurance companies doing business in a state can be assessed for certain obligations of insolvent insurancecompanies to such insolvent companies’ policyholders and claimants. Maximum assessments allowed in any one year generally vary between one percentand two percent of annual premiums written in that state, but it is possible that caps on such assessments could be raised if there are numerous or largeinsolvencies. In most states, guaranty fund assessments are recoverable either through future policy surcharges or offsets to state premium tax liabilities.The admitted market is subject to more state regulation than the E&S market, particularly with regard to rate and form filing requirements, restrictions onthe ability to exit lines of business, premium tax payments and membership in various state associations, such as guaranty funds. Some states havederegulated their commercial insurance markets. We cannot predict the effect that further deregulation would have on our business, financial condition orresults of operations.The state insurance regulators utilize a risk-based capital model to help assess the capital and surplus adequacy of insurance companies in relation toinvestment and insurance risks and identify insurers that are in, or are perceived as approaching, financial difficulty. This model establishes minimum capitalneeds based on the risks applicable to the operations of the individual insurer. The risk-based capital requirements for property-casualty insurance companiesmeasure three major areas of risk: asset risk, credit risk and underwriting risk. Under risk-based capital requirements, regulatory compliance is determined bythe ratio of a company’s total adjusted capital, as defined by the NAIC, to its company action level risk-based capital. Companies having less statutorysurplus than required by the risk-based capital requirements are subject to varying degrees of regulatory scrutiny and intervention, depending on the severityof the inadequacy. At December 31, 2018, the Company’s U.S.-based insurance subsidiaries had total adjusted statutory capital of $241.7 million, which is inexcess of the minimum risk-based capital requirement.In response to the growing threat of cyber-attacks in the insurance industry, certain jurisdictions have begun to consider new cybersecurity measures,including the adoption of cybersecurity laws and regulations which, among other things, would require insurance companies to establish and maintain acybersecurity program and implement and maintain cybersecurity policies and procedures. On October 24, 2017, the NAIC adopted its Insurance DataSecurity Model Law, intended to serve as35TABLE OF CONTENTSmodel legislation for states to enact in order to govern cybersecurity and data protection practices of insurers, insurance agents, and other licensed entitiesregistered under state insurance laws. The New York Department of Financial Services issued new regulations governing cybersecurity requirements forfinancial services companies, which became effective on March 1, 2017. Ohio’s governor signed Substitute Senate Bill 273 (“SSB 273”) on December 19,2018, which adopted cybersecurity requirements in Ohio that are similar to the NAIC Insurance Data Security Model Law. SSB 273 will become effective inearly 2019. We are currently monitoring whether the other states in which we conduct business adopt the NAIC’s Insurance Data Security Model Law.From time to time, states consider and/or enact laws that may alter or increase state authority to regulate insurance companies and insurance holdingcompanies. States also consider and/or enact laws that impact the competitive environment and marketplace for property-casualty insurance. Changes inlegislation or regulations and actions by regulators, including changes in administrative and enforcement policies, could require operational modificationsfrom time to time. We cannot predict the effect that such changes or actions would have on our business, financial condition or results of operations.Federal RegulationThe U.S. federal government generally has not directly regulated the insurance industry except for certain areas of the market, such as insurance forflood, nuclear and terrorism risks. However, the U.S. federal government has undertaken initiatives or considered legislation in several areas that may impactthe insurance industry, including tort reform, corporate governance and the taxation of reinsurance companies. The Dodd-Frank Wall Street Reform andConsumer Protection Act (the “Dodd-Frank Act”) established the Federal Insurance Office which is authorized to study, monitor and report to Congress onthe insurance industry and to recommend that the Financial Stability Oversight Council (“FSOC”) designate an insurer as an entity posing risks to the U.S.financial stability in the event of the insurer’s material financial distress or failure. In December 2013, the Federal Insurance Office issued a report onalternatives to modernize and improve the system of insurance regulation in the United States, including by increasing national uniformity through either afederal charter or effective action by the states. Additionally, the Dodd-Frank Act streamlined E&S placements, the payment of E&S taxes, the regulation ofcredit for reinsurance, and simplified the process for insurers to become an eligible E&S insurer in the U.S. In addition, legislation has been introduced fromtime to time that, if enacted, could result in the U.S. federal government assuming a more direct role in the regulation of the insurance industry, includingfederal licensing in addition to or in lieu of state licensing and reinsurance for natural catastrophes. Changes to federal legislation and administrative policiesin several areas, including changes in federal taxation, can also significantly impact the insurance industry and us.On January 12, 2015, the Terrorism Risk Insurance Act of 2002 and its successors, the Terrorism Risk Insurance Extension Act of 2005 and the TerrorismRisk Insurance Program Reauthorization Act of 2007 (collectively, the “Terrorism Acts”), were extended until 2020. Under the Terrorism Acts, commercialproperty and casualty insurers, in exchange for making terrorism insurance available, may be entitled to be reimbursed by the federal government for aportion of their aggregate losses. As required by the Terrorism Acts, we offer policyholders in specific lines of commercial insurance the option to electterrorism coverage.In order for a loss to be covered under the Terrorism Acts, the loss must meet the aggregate industry loss minimum and must be the result of an act ofterrorism as certified by the Secretary of the Treasury. Beginning in 2016, insurers participating in the Terrorism Acts are required to provide informationregarding insurance coverage for terrorism losses, including: (i) lines of business with exposure to such losses, (ii) premiums earned on such coverage, (iii)geographical location of exposures, (iv) pricing of such coverage, (v) the take-up rate for such coverage, and (vi) the amount of private reinsurance for acts ofterrorism purchased.Geographic InformationFor each of the years ended December 31, 2018, 2017 and 2016, 100% of our gross written premiums and net earned premiums were generated frompolicies issued to U.S.-based insureds.EmployeesAs of December 31, 2018, we had 750 employees located in the United States and Bermuda. All of our employees are full time. Our employees are notsubject to any collective bargaining agreement and we are not aware of any current efforts to implement such an agreement. We believe we have goodworking relations with our employees.Intellectual PropertyWe hold U.S. federal service mark registration of our corporate logo and several other company trademark registrations with the U.S. Patent andTrademark Office. Such registrations protect our intellectual property from confusingly similar use. We monitor our trademarks and service marks and protectthem from unauthorized use.36TABLE OF CONTENTSWe use licensed and proprietary systems and technologies in our underwriting. The licenses have terms that expire at various times through 2028. Webelieve that we can utilize other available systems and technologies in the event that the licenses are not renewed upon their expiration.Available InformationWe file annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and other information with the SEC. The SECmaintains an Internet web site that contains reports, proxy and information statements and other information regarding issuers, including us, that fileelectronically with the SEC. The address of that site is http://www.sec.gov. Our annual reports on Form 10-K, quarterly reports on Form 10-Q and currentreports on Form 8-K and other information filed by us with the SEC are available, without charge, on our Internet web site, http://www.jrgh.net, as soon asreasonably practicable after they are filed electronically with the SEC.

The information on our web site is not a part of this AnnualReport.37TABLE OF CONTENTSItem 1A.RISK FACTORSYou should carefully consider the following risks, together with the cautionary statement under the caption “Special Note Regarding Forward-LookingStatements” above and the other information included in this Annual Report. The risks described below are not the only ones we face. Additional risks thatare currently unknown to us or that we currently consider immaterial may also impair our business or materially adversely affect our financial condition orresults of operations. If any of the following risks actually occurs, our business, financial condition or results of operation could be materially adverselyaffected.Risks Related to Our Business and IndustryOur actual incurred losses may be greater than our loss and loss adjustment expense reserves, which could have a material adverse effect on our financialcondition and results of operations.Our financial condition and results of operations depend upon our ability to assess accurately the potential losses and loss adjustment expenses underthe terms of the insurance policies or reinsurance contracts we underwrite. Reserves do not represent an exact calculation of liability. Rather, reservesrepresent an estimate of what we expect the ultimate settlement and administration of claims will cost us, and our ultimate liability may be greater or less thancurrent reserves. These estimates are based on our assessment of facts and circumstances then known, as well as estimates of future trends in claim severity,claim frequency, judicial theories of liability and other factors. These variables are affected by both internal and external events that could increase ourexposure to losses, including changes in actuarial projections, claims handling procedures, inflation, climate change, economic and judicial trends, andlegislative changes. We continually monitor reserves using new information on reported claims and a variety of statistical techniques.In the insurance and reinsurance industry, there is always the risk that reserves may prove inadequate, and actual results always differ from our reserveestimates. It is possible for insurance and reinsurance companies to underestimate the cost of claims. Our estimates could prove to be low, and thisunderestimation could have a material adverse effect on our financial strength.Among the uncertainties we encounter in establishing our reserves for losses and related expenses in connection with our insurance businesses are:•When we write “occurrence” policies in our Excess and Surplus Lines segment, we are obligated to pay covered claims, up to the contractuallyagreed amount, for any covered loss that occurs while the policy is in force. Losses can emerge many years after a policy has lapsed. Accordingly,our first notice of a claim or group of claims may arise many years after a policy has lapsed. Approximately 93% of our net casualty loss reserves inthis segment are associated with “occurrence form” policies at December 31, 2018.​•Even when a claim is received (irrespective of whether the policy is a “claims made” or “occurrence” basis form), it may take considerable time tofully appreciate the extent of the covered loss suffered by the insured and, consequently, estimates of loss associated with specific claims canincrease over time.​•New theories of liability are enforced retroactively from time to time by courts. See also “The effect of emerging claim and coverage issues on ourbusiness is uncertain” risk factor herein.​•Volatility in the financial markets, economic events and other external factors may result in an increase in the number of claims and the severity ofthe claims reported. In addition, elevated inflationary conditions could, among other things, cause loss costs to increase.​•If claims became more frequent, even if we had no liability for those claims, the cost of evaluating these potential claims could escalate beyond theamount of the reserves we have established. As we enter new lines of business, or as a result of new theories of claims, we may encounter an increasein claims frequency and greater claims handling costs than we had anticipated.​•We regularly enter new lines of insurance, and as a consequence, we sometimes have to make estimates of future losses for risk classes with which wedo not have a great deal of experience. This lack of experience may contribute to making errors of judgment when establishing reserves.​In addition, reinsurance reserve estimates are typically subject to greater uncertainty than insurance reserve estimates, primarily due to reliance on theoriginal underwriting decisions made by the ceding company. As a result, we are subject to the risk that our ceding companies may not have adequatelyevaluated the risks reinsured by us and the premiums ceded may not adequately compensate us for the risks we assume. Other factors resulting in additionaluncertainty in establishing reinsurance reserves include:38TABLE OF CONTENTS•The increased lapse of time from the occurrence of an event to the reporting of the claim and the ultimate resolution or settlement of the claim.​•The diversity of development patterns among different types of reinsurance treaties.​•The necessary reliance on the ceding company for information regarding claims.​If any of our insurance or reinsurance reserves should prove to be inadequate for the reasons discussed above, or for any other reason, we will be requiredto increase reserves, resulting in a reduction in our net income and shareholders’ equity in the period in which the deficiency is identified. Future lossexperience substantially in excess of established reserves would also have a material adverse effect on future earnings and liquidity and financial rating,which would affect our ability to attract business and could affect our ability to retain or hire qualified personnel.Our risk management is based on estimates and judgments that are subject to significant uncertainties.Our approach to risk management relies on subjective variables that entail significant uncertainties. For example, we rely heavily on estimates ofprobable maximum losses for certain events that are generated by computer-run models. In addition, we rely on historical data and scenarios in managingcredit and interest rate risks in our investment portfolio. These estimates, models, data and scenarios may not produce accurate predictions and consequently,we could incur losses both in the risks we underwrite and to the value of our investment portfolio.Small changes in assumptions, which depend heavily on our judgment and foresight, can have a significant impact on the modeled outputs. Althoughwe believe that these probabilistic measures provide a meaningful indicator of the relative risk of certain events and changes to our business over time, thesemeasures do not predict our actual exposure to, nor guarantee our successful management of, future losses that could have a material adverse effect on ourfinancial condition and results of operations.If we are unable to retain key management and employees or recruit other qualified personnel, we may be materially adversely affected.We believe that our future success depends, in large part, on our ability to retain our experienced management team and key employees. For instance,our specialty insurance operations require the services of a number of highly experienced employees, including underwriters, to source quality business andanalyze and manage our risk exposure. There can be no assurance that we can attract and retain the necessary employees to conduct our business activities ona timely basis or at all. Our competitors may offer more favorable compensation arrangements to our key management or employees to incentivize them toleave our Company. Furthermore, our competitors may make it more difficult for us to hire their personnel by offering excessive compensation arrangementsto certain employees to induce them not to leave their current employment and bringing litigation against employees who do leave (and possibly us as well)to join us. Although we have employment agreements with all of our executive officers, we do not have employment agreements with our senior underwritersor claims personnel. We do not have key person insurance on the lives of any of our key management personnel. Our inability to attract and retain qualifiedpersonnel and the loss of services of key personnel could have a material adverse effect on our financial condition and results of operations.Adverse economic factors, including recession, inflation, periods of high unemployment or lower economic activity could result in the sale of fewer policiesthan expected or an increase in frequency or severity of claims and premium defaults or both, which, in turn, could affect our growth and profitability.Factors such as business revenue, economic conditions, the volatility and strength of the capital markets and inflation can all affect the business andeconomic environment. These same factors affect our ability to generate revenue and profits. In an economic downturn that is characterized by higherunemployment, declining spending and reduced corporate revenues, the demand for insurance products is adversely affected, which directly affects ourpremium levels and profitability. Negative economic factors may also affect our ability to receive the appropriate rate for the risk we insure with ourpolicyholders and may adversely affect the number of policies we can write, including with respect to our opportunities to underwrite profitable business. Inan economic downturn, our customers may have less need for insurance coverage, cancel existing insurance policies, modify their coverage, self-insure theirrisks, or not renew with us. Existing policyholders may exaggerate or even falsify claims to obtain higher claims payments. These outcomes would reduce ourunderwriting profit to the extent these factors are not reflected in the rates we charge.We underwrite a significant portion of our insurance in (i) the Excess and Surplus Lines segment in California, New York, Florida, Texas, and Illinois, (ii)the individual risk workers’ compensation business of the Specialty Admitted Insurance segment in North Carolina, Virginia, South Carolina and Georgia,and (iii) the fronting and program business of the Specialty Admitted Insurance segment in California, Michigan, North Carolina, New York, Pennsylvania,and New Jersey. Any economic downturn in any such state could have a material adverse effect on our financial condition and results of operations.39TABLE OF CONTENTSA decline in our financial strength rating may result in a reduction of new or renewal business.Companies, insurers and reinsurance brokers use ratings from independent ratings agencies as an important means of assessing the financial strength andquality of reinsurers. A.M. Best has assigned a financial strength rating of “A” (Excellent), which is the third highest of 15 ratings that A.M. Best issues, toeach of James River Insurance, James River Casualty, Falls Lake Fire and Casualty, Falls Lake National, Stonewood Insurance and JRG Re. A.M. Best assignsratings that are intended to provide an independent opinion of an insurance or reinsurance company’s ability to meet its obligations to policyholders andsuch ratings are not an evaluation directed to investors. A.M. Best periodically reviews our rating and may revise it downward or revoke it at its solediscretion based primarily on its analysis of our balance sheet strength (including capital adequacy and loss and loss adjustment expense reserve adequacy),operating performance and business profile. Factors that could affect such an analysis include but are not limited to:•if we change our business practices from our organizational business plan in a manner that no longer supports our A.M. Best’s rating;​•if unfavorable financial, regulatory or market trends affect us, including excess market capacity;​•if our losses exceed our loss reserves;​•if we have unresolved issues with government regulators;​•if we are unable to retain our senior management or other key personnel;​•if our investment portfolio incurs significant losses; or​•if A.M. Best alters its capital adequacy assessment methodology in a manner that would adversely affect our rating.​These and other factors could result in a downgrade of our rating. A downgrade of our rating could cause our current and future brokers and agents, retailbrokers and insureds to choose other, more highly-rated competitors. A downgrade of this rating could also increase the cost or reduce the availability ofreinsurance to us, increase collateral required for our assumed reinsurance business, or trigger termination of assumed and/or ceded reinsurance contracts.In addition, in view of the earnings and capital pressures recently experienced by many financial institutions, including insurance companies, it ispossible that rating organizations will heighten the level of scrutiny that they apply to such institutions, will increase the frequency and scope of their creditreviews, will request additional information from the companies that they rate and may increase the capital and other requirements employed in the ratingorganizations’ models for maintenance of certain ratings levels. It is possible that such reviews of us may result in adverse ratings consequences, which couldhave a material adverse effect on our financial condition and results of operations. A downgrade below “A-” or withdrawal of any rating could severely limitor prevent us from writing new and renewal insurance or reinsurance contracts. See also “Management’s Discussion and Analysis of Financial Condition andResults of Operations—Ratings.”We distribute products through a select group of brokers and agents, several of which account for a significant portion of our business, and there can be noassurance that such relationships will continue, or if they do continue, that the relationship will be on favorable terms to us. In addition, reliance onbrokers and agents subjects us to their credit risk.We distribute our products through a select group of brokers and agents. In 2018:•the Excess and Surplus Lines segment conducted business with two brokers that produced an aggregate of $439.7 million in gross written premiums,or 67.0% of that segment’s gross written premiums for the year;•the Specialty Admitted Insurance segment conducted business with one agency that produced $201.7 million in gross written premiums,representing 53.9% of that segment’s gross written premiums for the year; and​•the Casualty Reinsurance segment conducted business with two brokers that generated $96.4 million of gross written premiums, or 70.9% of thatsegment’s gross written premiums for the year.We cannot assure you that the relationship with any of these brokers will continue. Even if the relationships do continue, they may not be on terms thatare profitable for us. The termination of a relationship with one or more significant brokers or agents could result in lower direct written premiums and couldhave a material adverse effect on our results of operations or business prospects.There is a continuing trend toward consolidation among retail and wholesale brokers and agents. As brokers and agents consolidate and competitionamong them declines, they may seek and receive higher commissions. Increases in commission expense could reduce our underwriting profit.40TABLE OF CONTENTSCertain premiums from policyholders, where the business is produced by brokers or agents, are collected directly by the brokers or agents and forwardedto our insurance subsidiaries. In certain jurisdictions, when the insured pays its policy premium to brokers or agents for payment on behalf of our insurancesubsidiaries, the premiums might be considered to have been paid under applicable insurance laws and regulations. Accordingly, the insured would no longerbe liable to us for those amounts, whether or not we have actually received the premiums from that broker or agent. Consequently, we assume a degree ofcredit risk associated with brokers and agents. Where necessary, we review the financial condition of potential new brokers and agents before we agree totransact business with them. Although failures by brokers and agents to remit premiums have not been material to date, there may be instances where brokersand agents collect premiums but do not remit them to us and we may be required under applicable law to provide the coverage set forth in the policy despitethe absence of premiums.Because the possibility of these events depends in large part upon the financial condition and internal operations of our brokers and agents (which inmost cases is not public information), we are not able to quantify the exposure presented by this risk. If we are unable to collect premiums from brokers andagents in the future, underwriting profits may decline and our financial condition and results of operations could be materially adversely affected.We rely on a select group of customers for a significant portion of our business, and the loss of any of these customers, or a material reduction in businesswith any of these customers, would materially adversely affect our rate of growth, results of operations and financial condition.Our two largest customers accounted for approximately $294.3 million (Rasier LLC and its affiliates) and $201.7 million (Atlas General InsuranceServices) of our gross written premium in 2018, representing 25.2% and 17.3% of our gross written premiums in 2018, respectively. No other insuredgenerated 10.0% or more of consolidated gross written premiums for 2018. The loss of any of these customers, or a significant reduction in the amount ofbusiness that we conduct with such customers, could have a material adverse effect on our results of operations.We are subject to credit risk with regard to our reinsurance counterparties, insurance companies with which we have a fronting arrangement and anindemnification arrangement we have with an insured group of companies.Although reinsurance makes the assuming reinsurer liable to us to the extent of the risk ceded, we are not relieved of our primary liability to our insuredsas the direct insurer. At December 31, 2018, reinsurance recoverables on unpaid losses from our three largest reinsurers was $243.6 million in the aggregateand represented 52.1% of the total balance. Additionally, prepaid reinsurance premiums ceded to three reinsurers at December 31, 2018 was $53.7 million inthe aggregate, or 47.8% of the total balance of prepaid reinsurance premiums. At December 31, 2018, all of our material reinsurance recoverable amounts arefrom companies with A.M. Best ratings of “A-” or better or are collateralized by the reinsurer, but we cannot be sure that our reinsurers will pay all reinsuranceclaims on a timely basis or at all. For example, reinsurers may default in their financial obligations to us as the result of insolvency, lack of liquidity,operational failure, fraud, asserted defenses based on agreement wordings or the principle of utmost good faith, asserted deficiencies in the documentation ofagreements or for other reasons. The failure of a reinsurer to pay us does not lessen our contractual obligations to insureds. If a reinsurer fails to pay theexpected portion of a claim or claims, our net losses might increase substantially and materially adversely affect our financial condition. Any disputes withreinsurers regarding coverage under reinsurance contracts could be time-consuming, costly and uncertain of success.Downgrades to the credit ratings of our reinsurance counterparties may result in the reduction of rating agency capital credit provided by thosereinsurance contracts and could, therefore, result in a downgrade of our own credit ratings. In addition, under the reinsurance regulations, in many stateswhere our U.S. insurance subsidiaries are domiciled, certain reinsurers are required to collateralize their obligations to us and to the extent they do not do so,our ability for regulators to recognize this reinsurance will be impaired. We evaluate each reinsurance claim based on the facts of the case, historicalexperience with the reinsurer on similar claims and existing case law and include any amounts deemed uncollectible from the reinsurer in our reserve foruncollectible reinsurance. See also “Business—Purchase of Reinsurance.”Similarly, in our fronting business, which we conduct through our Specialty Admitted Insurance segment, we are primarily liable to the insureds becausewe have issued the policies. While we customarily require a collateral trust arrangement to secure the obligations of the insurance entity for which we arefronting, we do not obtain collateral in every instance and in situations where we do obtain collateral for the obligations of the other insurance entity, it ispossible that the collateral could be insufficient to cover all claims, either as a result of a decline in the value of the collateral, an increase in the obligationbeing collateralized, or a failure of management to monitor the adequacy of the collateral held. In that event, we would be contractually entitled to recoveryfrom the entity for which we are fronting, but it is possible that, for any of a variety of reasons, the other party could default in its obligations. See also“Business — Business Segments—Specialty Admitted Insurance Segment—Fronting & Program Business.”In addition, we are exposed to credit risk relating to a set of insurance contracts with an insured group of companies under which the Company payslosses and loss adjustment expenses on the contracts. The insured group of companies are contractually obligated to reimburse us for a significant portion ofthe losses and loss adjustment expenses paid on behalf of the41TABLE OF CONTENTSinsured parties. This reimbursement obligation is supported by collateral posted for our benefit, which cash equivalent collateral had a balance ofapproximately $1,099.2 million as of December 31, 2018. If the insured group of companies fails to reimburse us, and the collateral posted for our benefit tosupport the insured group of companies' reimbursement obligations is insufficient, our financial condition and results of operations could be materiallyadversely affected. See "Business — Purchase of Reinsurance — Amounts Recoverable from an Indemnifying Party."The failure of any of the loss limitations or exclusions we employ, or changes in other claims or coverage issues, could have a material adverse effect onour financial condition or results of operations.Although we seek to mitigate our loss exposure through a variety of methods, the future is inherently unpredictable. It is difficult to predict the timing,frequency and severity of losses with statistical certainty. It is not possible to completely eliminate our exposure to unforecasted or unpredictable events and,to the extent that losses from such risks occur, our financial condition and results of operations could be materially adversely affected.For instance, various provisions of our policies, such as limitations or exclusions from coverage or choice of forum, which have been negotiated to limitour risks, may not be enforceable in the manner we intend. At the present time, we employ a variety of endorsements to our policies that limit exposure toknown risks.In addition, we design our Excess and Surplus Lines segment’s policy terms to manage our exposure to expanding theories of legal liability like thosewhich have given rise to claims for lead paint, asbestos, mold, construction defects and environmental matters. Many of the policies we issue also includeconditions requiring the prompt reporting of claims to us and entitle us to decline coverage in the event of a violation of that condition. Also, many of ourpolicies limit the period during which a policyholder may bring a claim under the policy, which in many cases is shorter than the statutory period underwhich such claims can be brought against our policyholders. While these exclusions and limitations help us assess and reduce our loss exposure and helpeliminate known exposures to certain risks, it is possible that a court or regulatory authority could nullify or void an exclusion or legislation could beenacted modifying or barring the use of such endorsements and limitations. These types of governmental actions could result in higher than anticipatedlosses and loss adjustment expenses, which could have a material adverse effect on our financial condition or results of operations. In some instances, thesechanges may not become apparent until sometime after we have issued insurance policies that are affected by the changes. As a result, the full extent ofliability under our insurance contracts may not be known for many years after a contract is issued.We have exposure to losses arising from unpredictable natural disasters, terrorist acts, and other catastrophic events. Claims from these events couldreduce our earnings and cause volatility in our results of operations.We have exposure to losses arising from unpredictable natural disasters, terrorist acts, and other catastrophic events. Natural disasters, terrorist acts, andother catastrophes can cause losses in a variety of our property-casualty lines and generally result in an increase in the number of claims filed as well as theamount of compensation sought by claimants.The incidence and severity of catastrophes and terrorist acts are inherently unpredictable. The extent of losses from catastrophes is a function of thefrequency of loss events, the total amount of insured exposure in the area affected by each event and the severity of the events. Claims from catastrophicevents could exceed our amount of reinsurance purchased to protect us from such events, reduce our earnings and cash flows, cause volatility in our results ofoperations and cash flows for any fiscal period or materially impact our financial condition.Changing climate conditions may increase the frequency and severity of catastrophic events and thereby adversely affect our financial condition andresults.Over the past several years, changing weather patterns and climatic conditions, such as global warming, appear to have contributed to theunpredictability, frequency and severity of natural disasters and created additional uncertainty as to future trends and exposures. There is a growing scientificconsensus that global warming and other climate changes are increasing the frequency and severity of catastrophic weather events, such as hurricanes,tornadoes, windstorms, floods and other natural disasters. Such changes make it more difficult for us to predict and model catastrophic events, reducing ourability to accurately price our exposure to such events and mitigate our risks. Any increase in the frequency or severity of natural disasters may adverselyaffect our financial condition and results.We may have exposure to losses from terrorism for which we are required by law to provide coverage regarding such losses.U.S. insurers are required by state and federal law to offer coverage for terrorism in certain commercial lines, including workers’ compensation. Asdiscussed under “Business—Regulation—U.S. Insurance Regulation—Federal Regulation,” the Terrorism Acts require commercial property and casualtyinsurance companies to offer coverage for acts of terrorism, whether foreign or domestic, and established a federal assistance program through the end of 2020to help cover claims related to future terrorism-related losses. The impact of any terrorist act is unpredictable, and the ultimate impact on us would dependupon the nature, extent, location and timing of such an act.42TABLE OF CONTENTSThe effect of emerging claim and coverage issues on our business is uncertain.As industry practices and legal, judicial, social and other environmental conditions change, unexpected and unintended issues related to claims andcoverage may emerge. These issues may materially adversely affect our business by either broadening coverage beyond our underwriting intent or byincreasing the number or size of claims. In some instances, these changes may not become apparent until sometime after we have issued insurance orreinsurance contracts that are affected by the changes. As a result, the full extent of liability under our insurance or reinsurance contracts may not be knownfor many years after a contract is issued.Three examples of unanticipated risks that affected the insurance industry are:•Asbestos liability applied to manufacturers of products and contractors who installed those products;•Apportionment of liability for settlement assigned to subcontractors who may have been involved in mundane tasks (such as installing sheetrock ina home); and​•Court decisions, such as the 1995 Montrose decision in California, that read policy exclusions narrowly so as to expand coverage, thereby requiringinsurers to create and write new exclusions.​Our investment portfolio is subject to significant market and credit risks, which could result in a material adverse impact on our financial condition orresults of operations.Our results of operations depend, in part, on the performance of our investment portfolio. We seek to hold a diversified portfolio of investments that ismanaged by professional investment advisory management firms in accordance with our investment policy and periodically reviewed by our InvestmentCommittee. However, our investments are subject to general economic conditions and market risks as well as risks inherent to particular securities.Our primary market risk exposures are to changes in interest rates and equity prices. See Item 7A, “Quantitative and Qualitative Disclosures AboutMarket Risk.” In recent years, interest rates have been at or near historic lows. A protracted low interest rate environment would continue to place pressure onnet investment income, particularly related to fixed income securities and short-term investments, which, in turn, may materially adversely affect ouroperating results. Future increases in interest rates could cause the values of our fixed income securities portfolios to decline, with the magnitude of thedecline depending on the duration of our portfolio and the amount by which interest rates increase. Some fixed income securities have call or prepaymentoptions, which represent possible reinvestment risk in declining rate environments. Other fixed income securities such as mortgage-backed and asset-backedsecurities carry prepayment risk or, in a rising interest rate environment, may not pre-pay as quickly as expected. In addition, individual securities in ourfixed income securities portfolio are subject to credit risk and default. Downgrades in the credit ratings of fixed maturities can have a significant negativeeffect on the market valuation of such securities.The severe downturn in the public debt and equity markets beginning in 2008 resulted in significant realized and unrealized losses in our investmentportfolio. In the event of another financial crisis, we could incur substantial realized and unrealized investment losses in future periods, which would have amaterial adverse impact on our financial condition, results of operations, debt and financial strength ratings, insurance subsidiaries’ capital liquidity andability to access capital markets.The value of our investment portfolio is subject to the risk that certain investments may default or become impaired due to deterioration in the financialcondition of one or more issuers of the securities held, or due to deterioration in the financial condition of an insurer that guarantees an issuer’s payments ofsuch investments. Such defaults and impairments could reduce our net investment income and result in realized investment losses.We hold investments in actively-traded syndicated bank loans (15.6% of the carrying value of our invested assets as of December 31, 2018). Most ofthese loans are issued to sub-investment grade borrowers. While this class of investment has been profitable for us, a severe downturn in the markets couldmaterially adversely affect the value of these investments, including the possibility that we would suffer substantial losses on this portfolio. As ofDecember 31, 2018, the fair value of our investments in actively traded syndicated bank loans was $250.7 million.As of December 31, 2018, we held equity investments of $29.8 million in non-public limited liability companies that have invested in renewable energyinvestments. These investments were sponsored and are managed by an entity for which two of our directors serve as officers. We invested in the equity ofthese projects because we anticipate earning attractive risk-adjusted returns from these investments. However, our investments in these projects are illiquidand the ultimate results from these investments may be unknown for some time.We also invest in marketable equity securities. These securities are carried on the balance sheet at fair market value and are subject to potential lossesand declines in market value. Our invested assets also include interests in limited partnerships and privately held debt investments totaling $42.5 million atDecember 31, 2018. These investments were designed to provide diversification of risk and enhance the return on the overall portfolio. However, theseinvestments entail substantial risks and43TABLE OF CONTENTSare generally illiquid. Our investment portfolio is subject to increased valuation uncertainties when investment markets are illiquid. The valuation ofinvestments is more subjective when markets are illiquid, thereby increasing the risk that the estimated fair value (i.e., the carrying amount) does not reflectprices at which actual transactions would occur.Risks for all types of securities are managed through application of our investment policy, which establishes investment parameters that include (but arenot limited to) maximum percentages of investment in certain types of securities and minimum levels of credit quality, which we believe are withinguidelines established by the NAIC, BMA and various state insurance departments, as applicable.Although we seek to preserve our capital, we cannot be certain that our investment objectives will be achieved, and results may vary substantially overtime. In addition, although we seek to employ investment strategies that are not correlated with our insurance and reinsurance exposures, losses in ourinvestment portfolio may occur at the same time as underwriting losses and, therefore, exacerbate the adverse effect of the losses on us.We may become subject to additional government or market regulation which may have a material adverse impact on our business.Market disruptions like those experienced during the credit-driven financial market collapse in 2008, as well as the dramatic increase in the capitalallocated to alternative asset management during recent years, have led to increased governmental as well as self-regulatory scrutiny of the insurance industryin general. In addition, certain legislation proposing greater regulation of the industry is periodically considered by governing bodies of some jurisdictionsas well as the U.S. federal government, and the credit-driven equity market collapse may increase the likelihood that some increased regulation of theindustry is mandated.Because we are a Bermuda company, we are subject to changes in Bermuda law and regulation that may have a material adverse impact on ouroperations, including through the imposition of tax liability or increased regulatory supervision. In addition, we will be exposed to any changes in thepolitical environment in Bermuda.Our business could be materially adversely affected by changes in state laws, including those relating to asset and reserve valuation requirements,surplus requirements, limitations on investments and dividends, enterprise risk and risk-based capital requirements and, at the federal level, by laws andregulations that may affect certain aspects of the insurance industry, including proposals for preemptive federal regulation. The U.S. federal governmentgenerally 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 U.S. federal government has undertaken initiatives or considered legislation in several areas that may affect the insurance industry, includingtort reform, corporate governance and the taxation of reinsurance companies. The Dodd-Frank Act also established the Federal Insurance Office, which isauthorized to study, monitor and report to Congress on the insurance industry and to recommend that the FSOC designate an insurer as an entity posing risksto U.S. financial stability in the event of the insurer’s material financial distress or failure. In December 2013, the Federal Insurance Office issued a report onalternatives to modernize and improve the system of insurance regulation in the United States, including increasing national uniformity through either afederal charter or effective action by the states. Any additional regulations established as a result of the Dodd-Frank Act or actions in response to the FederalInsurance Office Report could increase our costs of compliance or lead to disciplinary action. In addition, legislation has been introduced from time to timethat, if enacted, could result in the U.S. federal government assuming a more direct role in the regulation of the insurance industry, including federal licensingin addition to or in lieu of state licensing and reinsurance for natural catastrophes. We are unable to predict whether any legislation will be enacted or anyregulations will be adopted, or the effect that any such developments could have on our business, financial condition or results of operations.The Bermuda insurance and reinsurance regulatory framework has become subject to increased scrutiny in many jurisdictions. The BMA sought“regulatory equivalency” which enables Bermuda’s commercial insurers to transact business with the European Union on a “level playing field”. Inconnection with its initial efforts to achieve equivalency under Solvency II, the BMA implemented and imposed additional requirements on the companies itregulates, such as JRG Re and Carolina Re. On November 26, 2015, via delegated act, the European Commission granted Bermuda’s commercial insurers fullequivalence in all areas of Solvency II for an indefinite period of time. The European Commission’s act was reviewed and approved by the EuropeanParliament and Council. On March 4, 2016, the delegated act was published in the official journal of the European Union. The grant of full equivalence cameinto force on March 24, 2016 and applies from January 1, 2016.Additionally, the regulatory environment surrounding information security and privacy is increasingly demanding. We are subject to numerous U.S.federal and state laws governing the protection of personal and confidential information of our clients and employees. We are subject to the New YorkDepartment of Financial Services’ Cybersecurity Regulations, which came into effect on March 1, 2017. In addition, the NAIC adopted an Insurance DataSecurity Model Law on October 24, 2017, which would require licensed insurance entities to comply with detailed information security requirements. Todate, Ohio and South Carolina have adopted the Insurance Data and Security Model Law. It is not yet known whether, and to what extent, other statelegislatures or insurance regulators where we operate will enact the Insurance Data Security Model Law in whole or44TABLE OF CONTENTSin part, or in a modified form. Such enactments, especially if inconsistent between states or with existing laws and regulations, could raise compliance costsor increase the risk of noncompliance, with the attendant risk of being subject to regulatory enforcement actions and penalties, as well as reputational harm.Any such events could potentially have an adverse impact on our business, financial condition or results of operations.It is impossible to predict what, if any, changes in the regulations applicable to us, the markets in which we operate, trade and invest or thecounterparties with which we do business may be instituted in the future. Any such regulation could have a material adverse impact on our business.We are subject to extensive regulation, which may materially adversely affect our ability to achieve our business objectives. In addition, if we fail tocomply with these regulations, we may be subject to penalties, including fines and suspensions, which may materially adversely affect our financialcondition and results of operations.Our admitted insurance and reinsurance subsidiaries are subject to extensive regulation, primarily by California (the domiciliary state for Falls Lake Fireand Casualty Company), Ohio (the domiciliary state for James River Insurance and Falls Lake National), North Carolina (the domiciliary state for StonewoodInsurance), Virginia (the domiciliary state for James River Casualty), Bermuda (the domicile of JRG Re and Carolina Re), and to a lesser degree, the otherjurisdictions in the United States in which we operate. Most insurance regulations are designed to protect the interests of insurance policyholders, as opposedto the interests of shareholders. These regulations generally are administered by a department of insurance in each state and, in the case of JRG Re andCarolina Re, the BMA in Bermuda, and relate to, among other things, authorizations to write certain lines of business, capital and surplus requirements,reserve requirements, rate and form approvals, investment and underwriting limitations, affiliate transactions, dividend limitations, cancellation and non-renewal of policies, changes in control, solvency, receipt of reinsurance credit, accounting principles and a variety of other financial and non-financialaspects of our business. These laws and regulations are regularly re-examined and any changes in these laws and regulations or new laws or interpretationsthereof may be more restrictive, could make it more expensive to conduct business or otherwise materially adversely affect our financial condition oroperations. State insurance departments and the BMA also conduct periodic examinations of the affairs of insurance companies and reinsurance companiesand require the filing of annual and other reports relating to financial condition, holding company issues and other matters. These regulatory requirementsmay impose timing and expense or other constraints that could materially adversely affect our ability to achieve some or all of our business objectives.In addition, regulatory authorities have broad discretion to deny or revoke licenses for various reasons, including the violation of regulations. Forexample, an insurer’s registration may be cancelled by the BMA on certain grounds specified in the Insurance Act, including failure by the insurer to complywith its obligations under the Insurance Act, or if the BMA believes that the insurer has not been carrying on business in accordance with sound insuranceprinciples. In some instances, where there is uncertainty as to applicability, we follow practices based on our interpretations of regulations or practices that webelieve are generally followed by the industry. These practices may turn out to be different from the interpretations of regulatory authorities. If we do nothave the requisite licenses and approvals or do not comply with applicable regulatory requirements, insurance regulatory authorities could preclude ortemporarily suspend us from carrying on some or all of our activities or otherwise penalize us. This could materially adversely affect our ability to operate ourbusiness.The admitted market is subject to more state regulation than the E&S market, particularly with regard to rate and form filing requirements, restrictions onthe ability to exit lines of business, premium tax payments and membership in various state associations, such as guaranty funds. Some states havederegulated their commercial insurance markets. We cannot predict the effect that further deregulation would have on our business, financial condition orresults of operations.The NAIC has developed a system to test the adequacy of statutory capital of U.S.-based insurers, known as risk-based capital or “RBC,” that many stateshave adopted. This system establishes the minimum amount of risk-based capital necessary for an insurer to support its overall business operations. Itidentifies property-casualty insurers that may be inadequately capitalized by looking at certain inherent risks of each insurer’s assets and liabilities and itsmix of net written premiums. Insurers falling below a calculated threshold may be subject to varying degrees of regulatory action, including supervision,rehabilitation or liquidation. Failure to maintain adequate risk-based capital at the required levels could materially adversely affect the ability of ourinsurance subsidiaries to maintain regulatory authority to conduct their business. See “Business—U.S. Insurance Regulation—State Regulation.”In addition, the various state insurance regulators have increased their focus on risks within an insurer’s holding company system that may poseenterprise risk to the insurer. In 2012, the NAIC adopted the NAIC Amendments. The NAIC Amendments, when adopted by the various states, are designed torespond to perceived gaps in the regulation of insurance holding company systems in the United States. One of the major changes is a requirement that aninsurance holding company system’s ultimate controlling person submit annually to its lead state insurance regulator an “enterprise risk report” thatidentifies activities, circumstances or events involving one or more affiliates of an insurer that, if not remedied properly, are likely to have a material adverseeffect upon the financial condition or liquidity of the insurer or its insurance holding company45TABLE OF CONTENTSsystem as a whole. Other changes include (i) requiring a controlling person to submit prior notice to its domiciliary insurance regulator of a divestiture ofcontrol, (ii) having detailed minimum requirements for cost sharing and management agreements between an insurer and its affiliates and (iii) expanding thetypes of agreements between an insurer and its affiliates to be filed with its domiciliary insurance regulator. The NAIC Amendments must be adopted by astate legislature and such state’s insurance regulator in order to be effective in that state. Each of California, North Carolina, Ohio and Virginia, the states inwhich our U.S. insurance subsidiaries are domiciled, include this enterprise risk report requirement.In 2012, the NAIC also adopted the ORSA Model Act. The ORSA Model Act, when adopted by the various states, will require an insurance holdingcompany system’s Chief Risk Officer to submit annually to its lead state insurance regulator an ORSA. The ORSA is a confidential internal assessmentappropriate to the nature, scale and complexity of an insurer of the material and relevant risks identified by the insurer associated with an insurer’s currentbusiness plan and the sufficiency of capital resources to support those risks. The ORSA Model Act must be adopted by a state legislature in order to beeffective in that state. Each of California, North Carolina, Ohio and Virginia, the states in which our U.S. insurance subsidiaries are domiciled, adopted andrequire an ORSA filing.We cannot predict with certainty the effect any enacted, proposed or future state or federal regulation or NAIC initiative may have on the conduct of ourbusiness. Furthermore, there can be no assurance that the regulatory requirements applicable to our business will not become more stringent in the future orresult in materially higher cost than current requirements. Changes in regulation of our business may materially reduce our profitability, limit our growth orotherwise materially adversely affect our operations.We may be unable to obtain reinsurance coverage at reasonable prices or on terms that provide us adequate protection.We purchase reinsurance in many of our lines of business to help manage our exposure to insurance and reinsurance risks that we underwrite and toreduce volatility in our results. In addition, JRG Re has managed its risk through retrocession arrangements with third-party reinsurers. A retrocession is apractice whereby a reinsurer cedes risk to one or more other reinsurers.The availability and cost of reinsurance are subject to prevailing market conditions, both in terms of price and available capacity, each of which canaffect our business volume and profitability. The availability of reasonably affordable reinsurance is a critical element of our business plan. One importantway we utilize reinsurance is to reduce volatility in claims payments by limiting our exposure to losses from large risks. Another way we use reinsurance is topurchase substantial protection against concentrated losses when we enter new markets. As a result, our ability to manage volatility and avoid significantlosses, expand into new markets or grow by offering insurance to new kinds of enterprises may be limited by the unavailability of reasonably pricedreinsurance. We may not be able to obtain reinsurance on acceptable terms or from entities with satisfactory creditworthiness. In such event, if we areunwilling to accept the terms or credit risk of potential reinsurers, we would have to reduce the level of our underwriting commitments, which would reduceour revenues.Many reinsurance companies have begun to exclude certain coverages from, or alter terms in, the reinsurance contracts we enter into with them. Someexclusions relate to risks that we cannot in turn exclude from the policies we write due to business or regulatory constraints. In addition, reinsurers areimposing terms, such as lower per occurrence and aggregate limits, on direct insurers that do not wholly cover the risks written by these direct insurers. As aresult, we, like other direct insurance companies, write insurance policies which to some extent do not have the benefit of reinsurance protection. These gapsin reinsurance protection expose us to greater risk and greater potential losses. For example, certain reinsurers have excluded coverage for terrorist acts orpriced such coverage at unreasonably high rates. Many direct insurers, including us, have written policies without terrorist act exclusions and in many caseswe cannot exclude terrorist acts because of regulatory constraints. We may, therefore, be exposed to potential losses as a result of terrorist acts. See also“Business—Purchase of Reinsurance.”We, or agents we have appointed, may act based on inaccurate or incomplete information regarding the accounts we underwrite, or such agents mayexceed their authority or commit fraud when binding policies on our behalf.We, and our MGAs and other agents who have the ability to bind our policies, rely on information provided by insureds or their representatives whenunderwriting insurance policies. While we may make inquiries to validate or supplement the information provided, we may make underwriting decisionsbased on incorrect or incomplete information. It is possible that we will misunderstand the nature or extent of the activities or facilities and the correspondingextent of the risks that we insure because of our reliance on inadequate or inaccurate information.In addition, in the Specialty Admitted Insurance segment, MGAs and other agents have the authority to bind policies on our behalf. If any such agentsexceed their authority or engage in fraudulent activities, our financial condition and results of operations could be materially adversely affected.46TABLE OF CONTENTSWe rely on our systems and employees, and those of certain third-party vendors and service providers in conducting our operations, and certain failures,including internal or external fraud, operational errors, systems malfunctions, or cyber-security incidents, could materially adversely affect our operations.We are exposed to many types of operational risk, including the risk of fraud by employees and outsiders, clerical and recordkeeping errors andcomputer or telecommunications systems malfunctions. Our business depends on our ability to process a large number of increasingly complex transactions.If any of our operational, accounting, or other data processing systems fail or have other significant shortcomings, we could be materially adversely affected.Similarly, we depend on our employees and could be materially adversely affected if one or more of our employees causes a significant operationalbreakdown or failure, either as a result of human error, intentional sabotage or fraudulent manipulation of our operations or systems.Third parties with whom we do business, including vendors that provide services or security solutions for our operations, could also be sources ofoperational and information security risk to us, including from breakdowns, failures, or capacity constraints of their own systems or employees. Any of theseoccurrences could diminish our ability to operate our business, or cause financial loss, potential liability to insureds, inability to secure insurance,reputational damage or regulatory intervention, which could materially adversely affect us.We rely on our multiple proprietary operating systems as well as operating systems of third-party providers to issue policies, pay claims, run modelingfunctions and complete various internal processes. We may be subject to disruptions of such operating systems arising from events that are wholly or partiallybeyond our control, which may include, for example, electrical or telecommunications outages, natural or man-made disasters, such as earthquakes,hurricanes, floods or tornados, or events arising from criminal or terrorist acts. Such disruptions may give rise to losses in service to insureds and loss orliability to us. In addition, there is the risk that our controls and procedures as well as our business continuity, disaster recovery and data security systemsprove to be inadequate. The computer systems and network systems we and others use could be vulnerable to unforeseen problems. These problems may arisein both our internally developed systems and the systems of third-party service providers. In addition, our computer systems and network infrastructurepresent security risks and could be susceptible to hacking, computer viruses, data breaches, or ransomware attacks. Any such failure could affect ouroperations and could materially adversely affect our results of operations by requiring us to expend significant resources to correct the defect, as well as byexposing us to litigation or losses not covered by insurance. Although we have business continuity plans and other safeguards in place, our businessoperations may be materially adversely affected by significant and widespread disruption to our physical infrastructure or operating systems and those ofthird-party service providers that support our business.Our operations rely on the secure processing, transmission and storage of confidential information in our computer systems and networks. Ourtechnologies, systems and networks may become the target of cyber-attacks or information security breaches that could result in the unauthorized release,gathering, monitoring, misuse, loss or destruction of our or our insureds’ or reinsured’s confidential, proprietary and other information, or otherwise disruptour or our insureds’, reinsured’s or other third parties’ business operations, which in turn may result in legal claims, regulatory scrutiny and liability,reputational damage, the incurrence of costs to eliminate or mitigate further exposure and the loss of customers. Although to date we have not experiencedany material losses relating to cyber-attacks or other information security breaches, there can be no assurance that we will not suffer such losses in the future.While we make efforts to maintain the security and integrity of our information technology networks and related systems, and we have implemented variousmeasures and an incident response protocol to manage the risk of, or respond to, a security breach or disruption, there can be no assurance that our securityefforts and measures will be effective or that attempted security breaches or disruptions would not be successful or damaging. Our risk and exposure to thesematters remains heightened because of, among other things, the evolving nature of these threats and the outsourcing of some of our business operations. As aresult, cyber-security and the continued development and enhancement of our controls, processes and practices designed to protect our systems, computers,software, data and networks from attack, damage or unauthorized access remain a priority. As cyber-threats continue to evolve, we may be required to expendsignificant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any information securityvulnerabilities.Disruptions or failures in the physical infrastructure or operating systems that support our business and customers, or cyber-attacks or security breachesof the networks, systems or devices that our customers use to access our products and services could result in customer attrition, regulatory fines, penalties orintervention, reputational damage, reimbursement or other compensation costs, and/or additional compliance costs, any of which could materially adverselyaffect our financial condition or results of operations.We may not be able to manage our growth effectively.We intend to grow our business in the future, which could require additional capital, systems development and skilled personnel. We cannot assure youthat we will be able to meet our capital needs, expand and maintain our systems and our internal controls effectively, allocate our human resources optimally,identify and hire qualified employees or incorporate47TABLE OF CONTENTSeffectively the components of any businesses we may acquire in our effort to achieve growth. The failure to manage our growth effectively could have amaterial adverse effect on our business, financial condition and results of operations.If we are unable to underwrite risks accurately and charge competitive yet profitable rates to our policyholders, our business, financial condition andresults of operations will be materially adversely affected.In general, the premiums for our insurance policies are established at the time a policy is issued and, therefore, before all of our underlying costs areknown. Like other insurance companies, we rely on estimates and assumptions in setting our premium rates. Establishing adequate premium rates isnecessary, together with investment income, to generate sufficient revenue to offset losses, loss adjustment expenses and other underwriting costs and to earna profit. If we do not accurately assess the risks that we assume, we may not charge adequate premiums to cover our losses and expenses, which wouldmaterially adversely affect our results of operations and our profitability. Alternatively, we could set our premiums too high, which could reduce ourcompetitiveness and lead to lower revenues.Pricing involves the acquisition and analysis of historical loss data and the projection of future trends, loss costs and expenses, and inflation trends,among other factors, for each of our products in multiple risk tiers and many different markets. In order to accurately price our policies, we:•collect and properly analyze a substantial volume of data from our insureds;​•develop, test and apply appropriate actuarial projections and rating formulas;​•closely monitor and timely recognize changes in trends; and​•project both frequency and severity of our insureds’ losses with reasonable accuracy.​We seek to implement our pricing accurately in accordance with our assumptions. Our ability to undertake these efforts successfully and, as a result,accurately price our policies, is subject to a number of risks and uncertainties, including:•insufficient or unreliable data;​•incorrect or incomplete analysis of available data;​•uncertainties generally inherent in estimates and assumptions;•our failure to implement appropriate actuarial projections and rating formulas or other pricing methodologies;​•regulatory constraints on rate increases;​•our failure to accurately estimate investment yields and the duration of our liability for loss and loss adjustment expenses; and​•unanticipated court decisions, legislation or regulatory action.The insurance and reinsurance business is historically cyclical, and we may experience periods with excess underwriting capacity and unfavorablepremium rates, which could materially adversely affect our business.Historically, insurers and reinsurers have experienced significant fluctuations in operating results due to competition, frequency and severity ofcatastrophic events, levels of capacity, adverse trends in litigation, regulatory constraints, general economic conditions and other factors. We haveexperienced these types of fluctuations during our Company’s short history. The supply of insurance and reinsurance is related to prevailing prices, the levelof insured losses and the level of capital available to the industry that, in turn, may fluctuate in response to changes in rates of return on investments beingearned in the insurance and reinsurance industry. As a result, the insurance and reinsurance business historically has been a cyclical industry characterized byperiods of intense price competition due to excessive underwriting capacity as well as periods when shortages of capacity increased premium levels. Demandfor insurance and reinsurance depends on numerous factors, including the frequency and severity of catastrophic events, levels of capacity, the introductionof new capital providers, general economic conditions and underwriting results of primary insurers. All of these factors fluctuate and may contribute to pricedeclines generally in the insurance and reinsurance industry.We cannot predict with certainty whether market conditions will improve, remain constant or deteriorate. Negative market conditions may impair ourability to underwrite insurance and reinsurance at rates we consider appropriate and commensurate relative to the risk assumed. If we cannot underwriteinsurance or reinsurance at appropriate rates, our ability to transact business will be materially adversely affected. Any of these factors could lead to a materialadverse effect on our business, financial condition and results of operations.48TABLE OF CONTENTSOur reinsurance business is subject to loss settlements made by ceding companies and fronting carriers, which could materially adversely affect ourperformance.Where JRG Re enters into assumed reinsurance contracts with third parties, all loss settlements made by the ceding company will be unconditionallybinding upon us, provided they are within the terms of the underlying policies and within the terms of the relevant contract. While we believe the cedingcompanies will settle such claims in good faith, we are bound to accept the claims settlements agreed to by the ceding companies. Under the underlyingpolicies, each ceding company typically bears the burden of proving that a contractual exclusion applies to a loss, and there may be circumstances where thefacts of a loss are insufficient to support the application of an exclusion. In such circumstances, we assume such losses under the reinsured policies, whichcould materially adversely affect our performance.Our operating results have in the past varied from quarter to quarter and may not be indicative of our long-term prospects.Our operating results are subject to fluctuation and have historically varied from quarter to quarter. We expect our quarterly results to continue tofluctuate in the future due to a number of factors, including the general economic conditions in the markets where we operate, the frequency of occurrence orseverity of catastrophic or other insured events, fluctuating interest rates, claims exceeding our loss reserves, competition in our industry, deviations fromexpected renewal rates of our existing policies and contracts, adverse investment performance and the cost of reinsurance and retrocessional coverage.In particular, we seek to underwrite products and make investments to achieve favorable returns on tangible equity over the long term. In addition, ouropportunistic nature and focus on long-term growth in tangible equity may result in fluctuations in total premiums written from period to period as weconcentrate on underwriting contracts that we believe will generate better long-term, rather than short-term, results. Accordingly, our short-term results ofoperations may not be indicative of our long-term prospects.We could be forced to sell investments to meet our liquidity requirements.We invest the premiums we receive from our insureds and ceding companies until they are needed to pay policyholder claims or until they arerecognized as profits. Consequently, we seek to manage the duration of our investment portfolio based on the duration of our loss and loss adjustmentexpense reserves to ensure sufficient liquidity and avoid having to liquidate securities to fund claims. Risks such as inadequate loss and loss adjustmentreserves or unfavorable trends in litigation could potentially result in the need to sell investments to fund these liabilities. Such sales could result insignificant realized losses depending on the conditions of the general market, interest rates and credit issues with individual securities.Our associates could take excessive risks, which could negatively affect our financial condition and business.As an insurance enterprise, we are in the business of binding certain risks. The associates who conduct our business, including executive officers andother members of management, underwriters, sales managers, investment professionals, product managers, sales agents, and other associates, as well as MGAs,do so in part by making decisions and choices that involve exposing us to risk. These include decisions such as setting underwriting guidelines andstandards, product design and pricing, determining which business opportunities to pursue and other decisions. We endeavor, in the design andimplementation of our compensation programs and practices, to avoid giving our associates incentives to take excessive risks. Associates may, however, takesuch risks regardless of the structure of our compensation programs and practices. Similarly, although we employ controls and procedures designed tomonitor associates’ business decisions and prevent us from taking excessive risks, these controls and procedures may not be effective. If our associates takeexcessive risks, the impact of those risks could have a material adverse effect on our financial condition and business operations.We may require additional capital in the future, which may not be available or available only on unfavorable terms.Our future capital requirements depend on many factors, including our ability to write new and renewal business successfully and to establish premiumrates and reserves at levels sufficient to cover losses. Our ability to underwrite depends largely upon the expected quality of our claims paying process andour perceived financial strength as estimated by potential insureds, brokers, other intermediaries and independent rating agencies. To the extent that ourexisting capital is insufficient to fund our future operating requirements, cover claim losses, or satisfy ratings agencies in order to maintain a satisfactoryrating, we may need to raise additional capital in the future through offerings of debt or equity securities or otherwise to:•fund liquidity needs caused by underwriting or investment losses;​•replace capital lost in the event of significant reinsurance losses or adverse reserve developments;​•satisfy letters of credit or guarantee bond requirements that may be imposed by our clients or by regulators;​•meet rating agency or regulatory capital requirements; or•respond to competitive pressures.​49TABLE OF CONTENTSAny equity or debt financing, if available at all, may be on terms that are unfavorable to us. Further, any additional capital raised through the sale ofequity could dilute shareholders' ownership interest in the Company and would likely cause the value of our shares to decline. Additional capital raisedthrough the issuance of debt would most likely result in creditors having rights, preferences and privileges senior or otherwise superior to those of the holdersof our shares and may limit our flexibility in operating our business and make it more difficult to obtain capital in the future. Disruptions, uncertainty, orvolatility in the capital and credit markets may also limit our access to capital required to operate our business. If we are not able to obtain adequate capital,or obtain it on favorable terms, our business, financial condition and results of operations could be materially adversely affected.If we are unable to keep pace with the technological advancements in the insurance industry, our ability to compete effectively could be impaired.We are committed to developing and maintaining information technology systems that will allow our insurance subsidiaries to compete effectively.There can be no assurance that the development of current technology for future use will not result in our being competitively disadvantaged, especially withthose carriers that have greater resources. If we are unable to keep pace with the advancements being made in technology, our ability to compete with otherinsurance companies who have advanced technological capabilities will be negatively affected. Further, if we are unable to effectively execute and update orreplace our key legacy technology systems as they become obsolete or as emerging technology renders them competitively inefficient, our competitiveposition and our cost structure could be adversely affected.We operate in a highly competitive environment and we may not continue to be able to compete effectively against larger or more well-establishedbusiness rivals.We face competition from other specialty insurance companies, standard insurance companies and underwriting agencies, as well as from diversifiedfinancial services companies that are larger than we are and that have greater financial, marketing and other resources than we do. Some of these competitorsalso have longer experience and more market recognition than we do in certain lines of business. In addition, it may be difficult or prohibitively expensivefor us to implement technology systems and processes that are competitive with the systems and processes of these larger companies.In particular, competition in the insurance and reinsurance industry is based on many factors, including price of coverage, the general reputation andperceived financial strength of the company, relationships with brokers, terms and conditions of products offered, ratings assigned by independent ratingagencies, speed of claims payment and reputation, and the experience and reputation of the members of our underwriting team in the particular lines ofinsurance and reinsurance we seek to underwrite. See “Business—Competition.”A number of new, proposed or potential legislative or industry developments could further increase competition in our industry. These developmentsinclude:•An increase in capital-raising by companies in our lines of business, which could result in new entrants to our markets and an excess of capital in theindustry;​•The deregulation of commercial insurance lines in certain states and the possibility of federal regulatory reform of the insurance industry, whichcould increase competition from standard carriers for our E&S lines of insurance business; and​•Changing practices facilitated by the Internet may lead to greater competition in the insurance business. Among the possible changes are shifts inthe way in which commercial insurance is purchased, which could affect both admitted and E&S lines.​We currently depend largely on the wholesale distribution model for our Excess and Surplus Lines segment’s premiums. If the wholesale distributionmodel were to be significantly altered by changes in the way E&S lines risks are marketed, including, without limitation, through use of the Internet, it couldhave a material adverse effect on our premiums, underwriting results and profits.There is no assurance that we will be able to continue to compete successfully in the insurance or reinsurance markets. Increased competition in thesemarkets could result in a change in the supply and/or demand for insurance or reinsurance, affect our ability to price our products at risk-adequate rates, affectour ability to retain business with existing customers, or underwrite new business on favorable terms. If this increased competition so limits our ability totransact business, our operating results could be materially adversely affected.​50TABLE OF CONTENTSIf actual renewals of our existing contracts do not meet expectations, our premiums written in future years and our future results of operations could bematerially adversely affected.Most of our contracts are written for a one-year term. In our financial forecasting process, we make assumptions about the renewal of our prior year’scontracts. The insurance and reinsurance industries have historically been cyclical businesses with intense competition, often based on price. If actualrenewals do not meet expectations or if we choose not to write a renewal because of pricing conditions, our premiums written in future years and our futureoperations would be materially adversely affected.We may change our underwriting guidelines or our strategy without shareholder approval.Our management has the authority to change our underwriting guidelines or our strategy without notice to our shareholders and without shareholderapproval. As a result, we may make fundamental changes to our operations without shareholder approval, which could result in our pursuing a strategy orimplementing underwriting guidelines that may be materially different from the strategy or underwriting guidelines described in the section titled “Business”or elsewhere in this Annual Report.Litigation and legal proceedings against our subsidiaries could have a material adverse effect on our business, financial condition and/or results ofoperations.As an insurance and reinsurance holding company, our subsidiaries are named as defendants in various legal actions in the ordinary course of business.We believe that the outcome of presently pending matters, individually and in the aggregate, will not have a material adverse effect on our consolidatedfinancial position. However, the outcomes of lawsuits cannot be predicted and, if determined adversely, could require us to pay significant damage amountsor to change aspects of our operations, which could have a material adverse effect on our financial results.Changes in accounting practices and future pronouncements may materially affect our reported financial results.Developments in accounting practices may require us to incur considerable additional expenses to comply, particularly if we are required to prepareinformation relating to prior periods for comparative purposes or to apply the new requirements retroactively. The impact of changes in current accountingpractices and future pronouncements cannot be predicted but may affect the calculation of net income, shareholders’ equity and other relevant financialstatement line items.Further, our U.S. insurance subsidiaries are required to comply with statutory accounting principles (“SAP”). SAP and various components of SAP (suchas actuarial reserving methodology) are subject to constant review by the NAIC and its task forces and committees, as well as state insurance departments, inan effort to address emerging issues and otherwise improve financial reporting. Various proposals are pending before committees and task forces of the NAIC,some of which, if enacted, could have negative effects on insurance industry participants. The NAIC continuously examines existing laws and regulations inthe United States. We cannot predict whether or in what form such reforms will be enacted and, if so, whether the enacted reforms will positively or negativelyaffect us.In addition, the NAIC Accounting Practices and Procedures manual provides that state insurance departments may permit insurance companiesdomiciled in their jurisdiction to depart from SAP by granting them permitted accounting practices. We cannot predict whether or when the insurancedepartments of the states of domicile of our competitors may permit them to utilize advantageous accounting practices that depart from SAP, the use of whichmay not be permitted by the insurance departments of the states of domicile of our U.S. insurance subsidiaries. Further, we cannot assure that future changesto SAP or components of SAP or the grant of permitted accounting practices to our competitors will not have a negative impact on us.Our ability to implement our business strategy could be delayed or adversely affected by Bermuda employment restrictions relating to the ability to obtainand retain work permits for key employees in Bermuda.Under Bermuda law, non-Bermudians (other than spouses of Bermudians and holders of permanent residents’ certificates) may not engage in any gainfuloccupation in Bermuda without a valid government work permit. A work permit may be granted or renewed upon showing that, after proper publicadvertisement, no Bermudian, spouse of a Bermudian or a holder of a permanent resident’s certificate who meets the minimum standards reasonably requiredby the employer has applied for the job. A work permit is issued with an expiry date (up to five years) and no assurances can be given that any work permitwill be issued or, if issued, renewed upon the expiration of the relevant term. If work permits are not obtained or are not renewed for our key employees (otherthan our Chief Executive Officer, who holds Bermudian and United States citizenship and therefore is not required to have a work permit in Bermuda or inany other jurisdiction in which we operate), we would lose their services, which could materially affect our business.51TABLE OF CONTENTSIf California, North Carolina, Ohio, or Virginia significantly increase the assessments our insurance companies are required to pay, our financialcondition and results of operations will suffer.Our insurance companies are subject to assessments in California (the domiciliary state for Falls Lake Fire and Casualty Company), North Carolina (thedomiciliary state for Stonewood Insurance), Ohio (the domiciliary state for James River Insurance and Falls Lake National) and Virginia (the domiciliary statefor James River Casualty), for various purposes, including the provision of funds necessary to fund the operations of the various insurance departments andthe state funds that pay covered claims under certain policies written by impaired, insolvent or failed insurance companies. These assessments are generallyset based on an insurer’s percentage of the total premiums written in the insurer’s state within a particular line of business. As our U.S.-based insurancesubsidiaries grow, our share of any assessments may increase. We cannot predict with certainty the amount of future assessments because they depend onfactors outside our control, such as insolvencies of other insurance companies. Significant assessments could result in higher than expected operatingexpenses and have a material adverse effect on our financial condition or results of operations.Our use of third-party claims administrators in certain lines of business may result in higher losses and loss adjustment expenses.Historically, our Excess and Surplus Lines and Specialty Admitted Insurance segments handled all claims using employed staff. As we have entered newlines of business, we now use third-party claims administrators and contract employees to administer claims subject to the supervision of our employed staff.It is possible that these contract employees and third-party claims administrators may achieve less desirable results on claims than has historically been thecase for our internal staff, which could result in significantly higher losses and loss adjustment expenses in those lines of business.Risks Related to TaxationThe ongoing effect of the 2017 Tax Act may have a significant impact on the Company. The Tax Act, enacted on December 22, 2017, introduced significant changes to the Code. The Tax Act contains provisions that reduce the highestmarginal U.S. corporate tax rate from 35% to 21%, impose a BEAT on income of a U.S. corporation determined without regard to certain otherwise deductiblepayments made to certain foreign affiliates (including premium or other consideration paid or accrued to a related foreign reinsurance company forreinsurance), and accelerates taxable income with respect to certain controlled foreign corporations. These provisions could materially affect us or ourshareholders. The Tax Act also includes provisions that could materially affect our shareholders as a result of provisions that broaden the definition of UnitedStates shareholder for purposes of the controlled foreign corporation (“CFC”) rules and make it more difficult for a foreign insurance company to avoid beingtreated as a PFIC.There is significant uncertainty regarding how these and other provisions of the Tax Act will be interpreted, and guidance may not be forthcoming. Theultimate impact of the Tax Act may differ from the Company’s description below due to changes in interpretations, as well as additional regulatory guidancethat may be issued. Any changes to, clarifications of, or guidance under the Tax Act could add significant expense and have a material adverse effect on ourresults of operations. Given the complexity of the Tax Act you are strongly encouraged to consult your own tax advisor regarding its potential impact on theU.S. federal income tax consequences to you in light of your particular circumstances.Base Erosion and Anti-Abuse Tax. The Tax Act’s BEAT provision imposes a minimum tax on “applicable taxpayers,” which are generally corporationsthat are part of a group with at least $500 million of applicable annual gross receipts and that make certain payments to related foreign persons, includingpayments that are deductible for U.S. tax purposes, payments to purchase depreciable or amortizable property, and reinsurance payments. BEAT subjects the“modified taxable income” of an applicable taxpayer to tax at a rate of 10% in 2019-2025, and 12.5% in 2026 and thereafter. In general, modified taxableincome is calculated by adding back to a taxpayer’s regular taxable income the amount of certain “base erosion tax benefits” with respect to certain paymentsto foreign affiliates, as well as the “base erosion percentage” of any net operating loss deductions. BEAT applies only to the extent it exceeds a taxpayer’sregular corporate income tax liability (determined without regard to certain tax credits).In response to the Tax Act, we made changes to our structure in 2018 to minimize the impact of BEAT that included the formation of Carolina Re, aBermuda-domiciled, wholly owned subsidiary of James River Group, Inc. Carolina Re is a Class 3A reinsurer that made an election to be taxed as a U.S.domestic corporation under Section 953(d) of the Code, effective January 1, 2018. In addition, as of January 1, 2018, we generally discontinued ceding 70%of our U.S.-written premiums to JRG Re and instead ceded 70% of our U.S.-written premiums to Carolina Re. Carolina Re also entered into a stop lossreinsurance agreement with JRG Re. As a result of these changes, we will not be subject to BEAT in 2019 if we have sufficient regular U.S. income taxliability compared to the BEAT liability. The applicability of BEAT depends on a number of factors, and absent regulations and other detailed guidance, it isuncertain whether we will be subject to BEAT in future periods.52TABLE OF CONTENTSU.S. persons who own our shares may be subject to U.S. federal income taxation on our undistributed earnings and may recognize ordinary income upondisposition of shares.If we are considered a PFIC as defined in Section 1297(a) of the Code for U.S. federal income tax purposes, a U.S. person who owns any of our sharescould be subject to adverse tax consequences, including becoming subject to a greater tax liability than might otherwise apply and to tax on amounts inadvance of when tax would otherwise be imposed, in which case your investment could be materially adversely affected. We believe that we are not and havenot been, and currently do not expect to become, a PFIC for U.S. federal income tax purposes. Our belief that we are not and have not been a PFIC is based, inpart, on the fact that the PFIC rules include provisions intended to provide an exception for qualifying insurance companies (“QIC”) actively engaged in theconduct of an insurance business. Generally, a QIC is a company (i) that would be subject to tax under special provisions related to insurance companies ifthe company was a U.S. entity, and (ii) the applicable insurance liabilities of which constitute more than 25% of its total assets as reported on the company’sapplicable financial statement. We believe that we are a QIC, however the scope of this exception is not entirely clear, especially in its application to holdingcompanies indirectly engaged in an insurance business, and there are no administrative pronouncements, judicial decisions or current regulations thatprovide guidance as to the application of the PFIC rules to insurance companies. New regulations or pronouncements interpreting or clarifying these rulesmay be forthcoming. We cannot predict what impact, if any, such guidance would have on an investor that is subject to U.S. federal income taxation. As aresult, we cannot assure you that we, or one of our subsidiaries, will not be deemed a PFIC by the U.S. Internal Revenue Service (the “IRS”). If we, or one ofour subsidiaries, were considered a PFIC, it could have material adverse tax consequences for an investor that is subject to U.S. federal income taxation.A non-U.S. corporation generally will be classified as a CFC if U.S. persons, each of whom owns, directly, indirectly, or constructively, at least 10% ofthe voting power or value of such corporation’s stock (“U.S. 10% Shareholders”), own in the aggregate more than 50% of the voting power or value of thestock of such corporation. The Tax Act eliminated the prohibition on “downward attribution” from non-U.S. persons to U.S. persons under the CFCconstructive ownership rules. As a result, our U.S. subsidiaries are deemed to own all of the stock of our non-U.S. subsidiaries (other than James River GroupHoldings UK Limited (“James River UK”)) for purposes of classifying those non-U.S. subsidiaries as CFCs. The legislative history under the Tax Actindicates that this change to the CFC constructive ownership rules was not intended to cause our non-U.S. subsidiaries to be treated as CFCs with respect to a10% U.S. Shareholder that is not related to our U.S. subsidiary. However, it is not clear whether the IRS or a court would interpret the change made by the TaxAct in a manner consistent with such indicated intent.Under these rules, if a foreign corporation is a CFC, each U.S. 10% Shareholder who owns directly or indirectly shares of the CFC on the last day of theCFC’s taxable year must annually include in its taxable income its pro rata share of the CFC’s “subpart F income,” even if no distributions are made. SubpartF income typically includes “foreign personal holding company income” (such as interest, dividends and other types of passive income), as well as insuranceand reinsurance income (including underwriting and investment income). In general (subject to the special rules applicable to “related person insuranceincome” described below), for purposes of taking into account insurance income, a foreign insurance company will be treated as a CFC if U.S. 10%Shareholders collectively own more than 25% of the voting power or value of the company’s shares at any point during any year. We cannot assure you thatwe are not and will not become a CFC. If you are a U.S. person, we strongly urge you to consult your own tax advisor concerning the CFC rules.Related Person Insurance Income. If (i) our gross income attributable to insurance or reinsurance policies pursuant to which the direct or indirectinsureds are our direct or indirect U.S. shareholders or persons related to such U.S. shareholders equals or exceeds 20% of our gross insurance income in anytaxable year; and (ii) direct or indirect insureds and persons related to such insureds own directly or indirectly 20% or more of the voting power or value ofour shares (together, the “RPII Test”), a U.S. person who owns any of our shares directly or indirectly on the last day of such taxable year would most likely berequired to include its allocable share of our related person insurance income for such taxable year in its income, even if no distributions are made. We do notbelieve that the 20% gross insurance income threshold has been, or will be, met. However, we cannot assure you that this will continue to be the case.Consequently, we cannot assure you that a person who is a direct or indirect U.S. shareholder will not be required to include amounts in its income in respectof related person insurance income in any taxable year.Dispositions of Our Shares. If a U.S. shareholder is treated as disposing of shares in a CFC of which it is a U.S. 10% Shareholder, or of shares in a foreigninsurance corporation that has related person insurance income and in which U.S. persons collectively own 25% or more of the voting power or value of thecompany’s shares, any gain from the disposition will generally be treated as a dividend to the extent of the U.S. shareholder’s portion of the corporation’sundistributed earnings and profits, as the case may be, that were accumulated during the period that the U.S. shareholder owned the shares. In addition, theshareholder will be required to comply with certain reporting requirements, regardless of the amount of shares owned by the direct or indirect U.S.shareholder.53TABLE OF CONTENTSThe Company, JRG Re and James River Group Holdings UK Limited may be subject to U.S. federal income taxation.The Company and JRG Re are each incorporated under the laws of Bermuda and James River UK is incorporated under the laws of England and Wales.Carolina Re is incorporated under the laws of Bermuda, but will be taxed as a U.S. domestic corporation as a result of an election under Section 953(d) of theCode. In general, a corporation organized under the laws of a foreign country or U.S. possession is subject to U.S. federal income tax on its net income only ifit is considered as engaged in a U.S. trade or business. We believe that the activities of each of the Company’s non-U.S. holding companies and JRG Re, ascontemplated, will not cause them to be treated as engaging in a U.S. trade or business and as such, will not be subject to current U.S. federal income taxationon their net income. However, there are no definitive standards provided by the Code, regulations or court decisions as to the specific activities thatconstitute being engaged in the conduct of a trade or business within the United States, and any such determination is essentially factual in nature and mustbe made annually. The IRS could successfully assert that our non-U.S. holding companies or JRG Re (or both) are engaged in a trade or business in the UnitedStates or, under the applicable income tax treaty, are engaged in a trade or business in the United States through a permanent establishment, and thus aresubject to current U.S. federal income taxation. If our non-U.S. holding companies or JRG Re were deemed to be engaged in a trade or business in the UnitedStates (or, under the applicable income tax treaty, were deemed to be so engaged through a permanent establishment), our non-U.S. holding companies orJRG Re, as applicable, would become subject to U.S. federal income tax on income “effectively connected” (or treated as effectively connected) with the U.S.trade or business and would become subject to the “branch profits” tax on earnings and profits that are both effectively connected with the U.S. trade orbusiness and deemed repatriated out of the United States. Any such federal tax liability could materially adversely affect our results of operations.U.S. tax-exempt organizations who own our shares may recognize unrelated business taxable income.A U.S. tax-exempt organization may recognize unrelated business taxable income if a portion of our subpart F insurance income is allocated to it. Ingeneral, subpart F insurance income will be allocated to a tax-exempt organization owning (or treated as owning) our shares if we are a CFC as discussedabove and it is a U.S. 10% Shareholder or we earn related person insurance income and we satisfy the RPII Test. We cannot assure you that U.S. personsholding our shares (directly or indirectly) will not be allocated subpart F insurance income. U.S. tax-exempt organizations should consult their own taxadvisors regarding the risk of recognizing unrelated business taxable income as a result of their ownership of our shares.We may become subject to U.S. withholding and information reporting requirements under the Foreign Account Tax Compliance Act (“FATCA”)provisions.The FATCA provisions of the Code generally impose a 30% withholding tax regime with respect to (i) certain U.S. source income (including interest anddividends) (“withholdable payments”) and (ii) “passthru payments” (generally, withholdable payments and payments that are attributable to withholdablepayments) made by foreign financial institutions (“FFIs”). Under proposed regulations promulgated by the U.S. Department of the Treasury on December 13,2018, on which taxpayers may rely until final regulations are issued, withholdable payments do not include gross proceeds from the sale or other dispositionof property that can produce U.S. source interest or dividends. As a general matter, FATCA was designed to require U.S. persons’ direct and indirectownership of certain non-U.S. accounts and non-U.S. entities to be reported to the IRS. The application of the FATCA withholding rules were phased inbeginning July 1, 2014, with withholding on foreign passthru payments made by FFIs taking effect after the date of publication of final regulations definingthe term foreign passthru payment.The United States has entered into intergovernmental agreements between the United States and Bermuda and between the United States and the UnitedKingdom (the “IGAs”), which potentially modify the FATCA withholding regime described above with respect to us and our common shares. There can be nocertainty as to whether we, Carolina Re or JRG Re will be treated as a FFI under FATCA. We strongly urge you to consult your own tax advisor regarding thepotential impact of FATCA, the IGAs and any non-U.S. legislation implementing FATCA.Changes in U.S. tax laws may be retroactive and could subject us and/or U.S. persons who own our shares to U.S. income taxation.Apart from enactment of the Tax Act, other legislative proposals or administrative or judicial developments could also result in an increase in the amountof U.S. tax payable by us or by an owner of our shares or reduce the attractiveness of our products. Any such developments could materially adversely affectour results of operations.The Tax Act, other tax laws and interpretations thereof, including with respect to whether a company is engaged in a U.S. trade or business, is a CFC, hasrelated party insurance income, is a PFIC, or is subject to BEAT, are subject to change, possibly on a retroactive basis. There are currently only proposedregulations regarding the RPII Test and the application of the PFIC rules to an insurance company. New regulations or pronouncements interpreting orclarifying such rules may be forthcoming from the IRS or the U.S. Department of the Treasury. We are not able to predict if, when or in what form suchguidance will be provided and whether such guidance will have a retroactive effect.54TABLE OF CONTENTSIf reinsurance premiums paid by our U.S. subsidiaries to Carolina Re or JRG Re do not reflect arm’s-length terms, the IRS could seek to recharacterize thepayments in a way that is unfavorable to us.The IRS is permitted to reallocate or recharacterize income, deductions or certain other items, and to make any other adjustment, to reflect the properamount, source or character of the taxable income in respect of payments among related parties to reflect an arm’s-length transaction. We have in placeintercompany loans from our U.S. subsidiaries to our parent company and have intercompany reinsurance agreements among consolidated entities. Webelieve the terms of these transactions are appropriate and reflect arm’s-length terms and are consistent with all applicable rules and regulations. It is possible,however, that the U.S. Department of the Treasury or the IRS may review our intercompany agreements and successfully assert, under Sections 482 or 845 ofthe Code, that they are not on an arm’s-length basis and that as a result, we owe taxes on account of past or future periods.Reduced tax rates for qualified dividend income may not be available in the future.We believe that the dividends paid on our common shares should qualify as “qualified dividend income” as long as the common shares are listed on anational securities exchange and we are not a PFIC. Qualified dividend income received by non-corporate U.S. persons is generally eligible for long-termcapital gain rates. While the Tax Act did not modify these rules, there has been proposed legislation before the U.S. Senate and House of Representatives thatwould exclude shareholders of certain foreign corporations from this advantageous tax treatment. If such legislation were to become law, non-corporate U.S.persons would no longer qualify for the reduced tax rate on the dividends paid by us.Our non-U.K. companies may be subject to U.K. tax that may have a material adverse effect on our operating results.We intend to operate in such a manner so that none of our companies other than our intermediate holding company incorporated in the United Kingdomshould be resident in the U.K. for tax purposes or have a permanent establishment in the U.K. Accordingly, we expect that none of our companies other thanJames River UK should be subject to U.K. taxation. However, since applicable law and regulations do not conclusively define the activities that constituteconducting business in the U.K. through a permanent establishment, the U.K. HM Revenue & Customs might contend successfully that one or more of ourother companies is conducting business in the U.K. through a permanent establishment in the U.K., and therefore such entities could become subject to U.K.taxation.We may become subject to taxes in Bermuda after March 31, 2035, which may have a material adverse effect on our results of operations and yourinvestment.The Bermuda Minister of Finance, under the Exempted Undertakings Tax Protection Act 1966 of Bermuda, as amended, has given us an assurance that ifany legislation is enacted in Bermuda that would impose tax computed on profits or income, or computed on any capital asset, gain or appreciation, or anytax in the nature of estate duty or inheritance tax, then the imposition of any such tax will not be applicable to us or any of our operations, shares, debenturesor other obligations until March 31, 2035, except insofar as such tax applies to persons ordinarily resident in Bermuda or to any taxes payable by us inrespect of real property owned or leased by us in Bermuda. We cannot assure you that we will not be subject to any Bermuda tax after March 31, 2035.55TABLE OF CONTENTSRisks Related to Ownership of Our Common SharesThe price of our common shares may fluctuate significantly and you could lose all or part of your investment.Volatility in the market price of our common shares may prevent you from being able to sell your common shares at or above the price you paid for yourcommon shares. The market price for our common shares could fluctuate significantly for various reasons, including, without limitation:•our operating and financial performance and prospects;​•our quarterly or annual earnings or earnings estimates, or those of other companies in our industry;​•failure to meet external expectations or management guidance;​•the loss of one or more individually large clients, and its impact on our growth rate, profitability and financial condition;​•exposure to capital market risks related to changes in interest rates, realized investment losses, credit spreads, equity prices, foreign exchange ratesand performance of insurance-linked investments;​•our creditworthiness, financial condition, performance and prospects;​•termination of payment of dividends on our common shares, or payment of a reduced amount of dividends;​•actual or anticipated growth rates relative to our competitors;​•perceptions of the investment opportunity associated with our common shares relative to other investment alternatives;​•speculation by the investment community regarding our business;​•future announcements concerning our business or our competitors’ businesses;​•the public’s reaction to our press releases, other public announcements and filings with the SEC;​•changes in accounting standards, policies, guidance, interpretations or principles;​•market and industry perception of our success, or lack thereof, in pursuing our strategy;​•strategic actions by us or our competitors, such as acquisitions, restructurings, significant contracts or joint ventures;​•catastrophes that are perceived by investors as impacting the insurance and reinsurance market in general;​•changes in laws or government regulation, including tax or insurance laws and regulations;​•potential characterization of us as a PFIC;​•general market, economic and political conditions;​•changes in conditions or trends in our industry, geographies or customers;​•arrival and departure of key personnel;​•the number of common shares that are publicly traded;•the offering and issuance of common shares by us, or sales of common shares by our directors or executive officers; and​•adverse resolution of litigation against us.​In addition, stock markets, including the NASDAQ Stock Market (the market on which our common shares are traded), have experienced price andvolume fluctuations that have affected and continue to affect the market prices of equity securities issued by many companies, including companies in ourindustry. In the past, some companies that have had volatile market prices for their securities have been subject to class action or derivative lawsuits. Thefiling of a lawsuit against us, regardless of the outcome, could have a negative effect on our business, as it could result in substantial legal costs and adiversion of management’s attention and resources.56TABLE OF CONTENTSAs a result of the factors described above, shareholders may not be able to resell their common shares at or above their purchase price or may not be ableto resell them at all. These market and industry factors may materially reduce the market price of our common shares, regardless of our operating performance.If securities or industry analysts do not continue to publish research or publish misleading or unfavorable research about our business, our common shareprice and trading volume could decline.The trading market for our common shares depends in part on the research and reports that securities or industry analysts publish about us or ourbusiness. If one or more of these analysts downgrades our shares or publishes misleading or unfavorable research about our business, our share price wouldlikely decline. If one or more of these analysts ceases coverage of our Company or fails to publish reports on us regularly, demand for our shares coulddecrease, which could cause our share price or trading volume to decline.Failure to maintain effective internal controls in accordance with Sarbanes-Oxley could have a material adverse effect on our business and common shareprice.As a public company with SEC reporting obligations, we are required to document and test our internal control procedures to satisfy the requirements ofSection 404(b) of Sarbanes-Oxley, which require annual assessments by management of the effectiveness of our internal control over financial reporting.During the course of our assessment, we may identify deficiencies that we are unable to remediate in a timely manner. Testing and maintaining ourinternal control over financial reporting may also divert management’s attention from other matters that are important to the operation of our business. Wemay not be able to conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with Section 404(b) ofSarbanes-Oxley. If we conclude that our internal control over financial reporting is not effective, we cannot be certain as to the timing of completion of ourevaluation, testing and remediation actions or its effect on our operations. Moreover, any material weaknesses or other deficiencies in our internal controlover financial reporting may impede our ability to file timely and accurate reports with the SEC. Any of the above could cause investors to lose confidence inour reported financial information or our common share listing on the NASDAQ Stock Market to be suspended or terminated, which could have a negativeeffect on the trading price of our common shares.Our bye-laws permit non-employee members of our board of directors and their affiliates to compete with us, which may result in conflicts of interest.Our bye-laws provide that members of our board of directors (other than those who are our officers, managers or employees) and their affiliates do nothave any duty to (i) communicate or present to the Company any investment or business opportunity or prospective transaction or arrangement in which theCompany may have any interest or expectancy or (ii) refrain from engaging, directly or indirectly, in the same business activities or similar business activitiesor lines of business in which we operate. Bryan Martin and David Zwillinger, each a Class I director of the Company, are officers of D. E. Shaw & Co., L.P.and its affiliates (collectively, “D. E. Shaw”). D. E. Shaw is a global investment and technology development firm, which among other things, is in thebusiness of making investments in companies. Our bye-laws will not restrict our non-employee directors, or their affiliates, including D. E. Shaw, fromacquiring and holding interests in businesses that compete directly or indirectly with us. For example, D. E. Shaw is currently engaged in the reinsurancebusiness. Our non-employee directors and their affiliates, including D. E. Shaw, may also pursue acquisition opportunities that may be complementary to ourbusiness and, as a result, those acquisition opportunities may not be available to us. These potential conflicts of interest could have a material adverse effecton our business, financial condition, results of operations or prospects if we are unable to pursue attractive corporate opportunities because they are allocatedby our non-employee directors to themselves or their affiliates instead of being presented to us.We depend upon dividends and distributions from our subsidiaries, and we may be unable to distribute dividends to our shareholders to the extent we donot receive dividends from our subsidiaries.We are a holding company that has no substantial operations of our own and, accordingly, we rely primarily on cash dividends or distributions from ouroperating subsidiaries to pay our operating expenses and any dividends that we may pay to shareholders. The payment of dividends by our insurance andreinsurance subsidiaries is limited under the laws and regulations of its applicable domicile. These regulations stipulate the maximum amount of annualdividends or other distributions available to shareholders without prior approval of the relevant regulatory authorities. As a result of such regulations, we maynot be able to pay our operating expenses as they become due and our payment of future dividends to shareholders may be limited.The payment of dividends by our subsidiaries to us is limited by statute. In general, the laws and regulations applicable to our U.S. insurancesubsidiaries limit the aggregate amount of dividends or other distributions that they may declare or pay within any 12 month period without advanceregulatory approval. In Ohio, the domiciliary state of Falls Lake National and James River Insurance, this limitation is the greater of statutory net income forthe preceding calendar year or 10% of the statutory surplus at the end of the preceding calendar year, provided that such dividends may only be paid out ofearned surplus of each of the companies, without obtaining regulatory approval. In North Carolina, the domiciliary state of Stonewood57TABLE OF CONTENTSInsurance, this limitation is the greater of statutory net income excluding realized capital gains for the preceding calendar year or 10% of the statutory surplusat the end of the preceding calendar year, provided that such dividends may only be paid out of unassigned surplus without obtaining regulatory approval. InVirginia, the domiciliary state of James River Casualty, this limitation is the greater of statutory net income excluding realized capital gains for the precedingcalendar year or 10% of the statutory surplus at the end of the preceding calendar year, provided that such dividends may only be paid out of unassignedsurplus without obtaining regulatory approval. In California, the domiciliary state of Falls Lake Fire and Casualty Company, this limitation is the greater ofstatutory net income for the preceding calendar year or 10% of the statutory surplus at the end of the preceding calendar year, provided that such dividendsmay only be paid out of unassigned surplus without obtaining regulatory approval. Moreover, as a condition to obtaining its license in California, Falls LakeFire and Casualty Company provided a commitment to the California Department of Insurance that it would not pay any shareholder dividends for a five-yearperiod commencing January 1, 2016 without prior written approval. In addition, insurance regulators have broad powers to prevent reduction of statutorysurplus to inadequate levels and could refuse to permit the payment of dividends calculated under any applicable formula. See “Business—Regulation—U.S.Insurance Regulation—State Regulation” for more information. In addition, dividends paid by our U.S. subsidiaries to our U.K. holding company are subjectto a 5% withholding tax by the IRS. Under U.K. domestic law, no withholding tax is applied to dividends paid by U.K. tax resident companies.JRG Re, which is domiciled in Bermuda, is registered as a Class 3B insurer under the Insurance Act. The Insurance Act, the conditions listed in theinsurance license and the applicable approvals issued by the BMA provide that JRG Re is required to maintain a minimum statutory solvency margin of$103.1 million as of December 31, 2018. See “Business—Regulation—Bermuda Insurance Regulation—Minimum Solvency Margin and Enhanced CapitalRequirements” for more information. A Class 3B insurer is prohibited from declaring or paying a dividend if it fails to meet, before or after declaration orpayment of such dividend, its: (i) requirements under the Companies Act, (ii) minimum solvency margin, (iii) enhanced capital requirement or (iv) minimumliquidity ratio. If a Class 3B insurer fails to meet its minimum solvency margin or minimum liquidity ratio on the last day of any financial year, it isprohibited from declaring or paying any dividends during the next financial year without the approval of the BMA. In addition, JRG Re, as a Class 3Binsurer, is prohibited from declaring or paying in any financial year dividends of more than 25% of its total statutory capital and surplus (as shown on itsprevious financial year’s statutory balance sheet) unless it files (at least seven days before payment of such dividends) with the BMA an affidavit signed by atleast 2 directors (one of whom must be a Bermuda resident director if any of the insurer’s directors are resident in Bermuda) and the principal representativestating that it will continue to meet its solvency margin and minimum liquidity ratio. Where such an affidavit is filed, it shall be available for publicinspection at the offices of the BMA. See “Business— Regulation—Bermuda Insurance Regulation—Restrictions on Dividends and Distributions” for moreinformation.The inability of our subsidiaries to pay dividends or make distributions to us, including as a result of regulatory or other restrictions, may prevent usfrom paying our expenses or paying dividends to our shareholders.We cannot assure you that we will declare or pay dividends on our common shares in the future.We have paid dividends to our shareholders in each quarter since the first quarter of 2015, which was the first full quarter after completion of our IPO.The declaration, payment and amount of future dividends is subject to the discretion of our board of directors. Our board of directors may take into account avariety of factors when determining whether to declare any future dividends, including (1) our financial condition, liquidity, results of operations (includingour ability to generate cash flow in excess of expenses and our expected or actual net income), retained earnings and collateral and capital requirements, (2)general business conditions, (3) legal, tax and regulatory limitations, (4) contractual prohibitions and other restrictions, (5) the effect of a dividend ordividends upon our financial strength ratings and (6) any other factors that our board of directors deems relevant. See “Item 5. Market For Registrant’sCommon Equity, Related Stockholder Matters and Issuer Purchases Of Equity Securities - Dividends.” We cannot assure you that we will continue to paydividends in the future, or that the amount of any such dividend will not decline from prior dividends we have paid.Dividends paid by our U.S. subsidiaries to James River UK may not be eligible for benefits under the U.S.-U.K. income tax treaty.Under U.S. federal income tax law, dividends paid by a U.S. corporation to a non-U.S. shareholder are generally subject to a 30% withholding tax, unlessreduced by treaty. The income tax treaty between the United Kingdom and the United States (the “U.K. Treaty”) reduces the rate of withholding tax oncertain dividends to 5%. Were the IRS to contend successfully that James River UK is not eligible for benefits under the U.K. Treaty, any dividends paid byJames River Group, Inc., our U.S. holding company, to James River UK would be subject to the 30% withholding tax. Such a result would substantiallyreduce the amount of dividends that our shareholder may receive.58TABLE OF CONTENTSFuture sales of our common shares, or the possibility of such sales, may cause the trading price of our common shares to decline and could impair ourability to raise capital through subsequent equity offerings.Future sales of substantial amounts of our common shares in the public market, or the perception that these sales could occur, could cause the marketprice of our common shares to decline and impair our ability to raise capital through the sale of additional shares.In the future, we may issue additional common shares or other equity or debt securities convertible into common shares in connection with a financing,acquisition or employee arrangement or otherwise. Any of these issuances could result in substantial dilution to our existing shareholders and could causethe trading price of our common shares to decline.Our bye-laws and provisions of Bermuda law may impede or discourage a change of control transaction, which could deprive our investors of theopportunity to receive a premium for their shares.Our bye-laws and provisions of Bermuda law to which we are subject contain provisions that could discourage, delay or prevent “change of control”transactions or changes in our board of directors and management that certain shareholders may view as beneficial or advantageous. These provisionsinclude, among others:•the total voting power of any U.S. person owning more than 9.5% of our common shares will be reduced to 9.5% of the total voting power of ourcommon shares, excluding shareholders that held more than 9.5% of our common shares on the day of completion of our IPO;​•our board of directors has the authority to issue preferred shares without shareholder approval, which could be used to dilute the ownership of apotential hostile acquirer;•our shareholders may only remove directors for cause;​​•there are advance notice requirements for shareholders with respect to director nominations and actions to be taken at annual meetings; and​​•under Bermuda law, for so long as JRG Re and Carolina Re are registered under the Insurance Act, the BMA may object to a person holding morethan 10%, 20%, 33% or 50% of our common shares if it appears to the BMA that the person is not or is no longer fit and proper to be such a holder(See “— There are regulatory limitations on the ownership and transfer of our common shares.”).The foregoing factors could impede a merger, takeover or other business combination, which could reduce the market value of our shares.We may repurchase your common shares without your consent.Under our bye-laws and subject to Bermuda law, we have the option, but not the obligation, to require a shareholder, other than shareholders holdingmore than 9.5% of our common shares on the day of completion of our IPO, to sell to us at fair market value the minimum number of common shares which isnecessary to avoid or cure any adverse tax consequences or materially adverse legal or regulatory treatment to us, our subsidiaries or our shareholders, if ourboard of directors reasonably determines, in good faith, that failure to exercise this option would result in such adverse consequences or treatment.Bermuda law differs from the laws in effect in the United States and may afford less protection to holders of our shares.We are organized under the laws of Bermuda. As a result, our corporate affairs are governed by the Companies Act, which differs in some materialrespects from laws typically applicable to U.S. corporations and shareholders, including the provisions relating to interested directors, amalgamations,mergers and acquisitions, takeovers, shareholder lawsuits and indemnification of directors. Generally, the duties of directors and officers of a Bermudacompany are owed to the company only. Shareholders of Bermuda companies typically do not have rights to take action against directors or officers of thecompany and may only do so in limited circumstances. Class actions are not available under Bermuda law. The circumstances in which derivative actionsmay be available under Bermuda law are substantially more proscribed and less clear than they would be to shareholders of U.S. corporations. The Bermudacourts, however, would ordinarily be expected to permit a shareholder to commence an action in the name of a company to remedy a wrong to the companywhere the act complained of is alleged to be beyond the corporate power of the company or illegal, or would result in the violation of the company’smemorandum of association or bye-laws. Furthermore, consideration would be given by a Bermuda court to acts that are alleged to constitute a fraud againstminority shareholders or, for instance, where an act requires the approval of a greater percentage of the company’s shareholders than that which actuallyapproved it.When the affairs of a company are being conducted in a manner that is oppressive or prejudicial to the interests of some shareholders, one or moreshareholders may apply to the Supreme Court of Bermuda, which may make such order as it sees fit, including an order regulating the conduct of thecompany’s affairs in the future or ordering the purchase of the shares of any shareholders by other shareholders or by the company. Additionally, under ourbye-laws and as permitted by Bermuda law,59TABLE OF CONTENTSeach shareholder has waived any claim or right of action against our directors or officers for any action taken by directors or officers in the performance oftheir duties, except for actions involving fraud or dishonesty. In addition, the rights of holders of our common shares and the fiduciary responsibilities of ourdirectors under Bermuda law are not as clearly established as under statutes or judicial precedent in existence in jurisdictions in the United States,particularly the State of Delaware. Therefore, holders of our common shares may have more difficulty protecting their interests than would shareholders of acorporation incorporated in a jurisdiction within the United States.There are regulatory limitations on the ownership and transfer of our common shares.Common shares may be offered or sold in Bermuda only in compliance with the provisions of the Investment Business Act 2003 and the ExchangeControl Act 1972 and related regulations of Bermuda, which regulate the sale of securities in Bermuda. In addition, the permission of the BMA is requiredunder the provisions of the Exchange Control Act 1972 and related regulations for all issuances and transfers of shares of Bermuda companies to or from anon-resident of Bermuda for exchange control purposes, other than where the BMA has granted a general permission. The BMA, in its notice to the publicdated June 1, 2005 has granted a general permission for the issue and subsequent transfer of any securities of a Bermuda company from and/or to a non-resident of Bermuda for exchange control purposes for so long as any “equity securities” of such company are listed on an appointed stock exchange, whichincludes the NASDAQ Stock Market. This general permission will apply to our common shares, but would cease to apply if we were to cease to be listed onthe NASDAQ Stock Market.In connection with the IPO, we received consent from the BMA to issue and transfer freely any of our shares, options, warrants, depository receipts, rightsloan notes, debt instruments or other securities to and among persons who are either residents or non-residents of Bermuda for exchange control purposes.The Insurance Act requires that where the shares of the registered insurer, or the shares of its parent company, are traded on a recognized stock exchange,and a person becomes a 10%, 20%, 33% or 50% shareholder controller of the insurer, that person shall, within 45 days, notify the BMA in writing that he hasbecome such a controller. In addition, a person who is a shareholder controller of an insurer whose shares or the shares of its parent company (if any) aretraded on a recognized stock exchange must serve on the BMA a notice in writing that he has reduced or disposed of his holding in the insurer where theproportion of voting rights in the insurer held by him will have reached or has fallen below 10%, 20%, 33% or 50% as the case may be, not later than 45 daysafter such disposal. This requirement will apply to us as long as our shares are listed on the NASDAQ Stock Market or another stock exchange recognized bythe BMA. The BMA may, by written notice, object to a person holding 10%, 20%, 33% or 50% of our common shares if it appears to the BMA that theperson is not fit and proper to be such a holder. The BMA may require the holder to reduce its shareholding in us and may direct, among other things, that thevoting rights attaching to its shares shall not be exercisable. A person that does not comply with such a notice or direction from the BMA will be guilty of anoffense.JRG Re and Carolina Re are also required to notify the BMA in writing in the event any person has become or has ceased to be a controller or an officerof it (an officer includes a director, chief executive or senior executive performing duties of underwriting, actuarial, risk management, compliance, internalaudit, finance or investment matters).​​​​Except in connection with the settlement of trades or transactions entered into through the facilities of the NASDAQ Stock Market, our board of directorsmay generally require any shareholder or any person proposing to acquire our common shares to provide the information required under our bye-laws. If anysuch shareholder or proposed acquiror does not provide such information, or if our board of directors has reason to believe that any certification or otherinformation provided pursuant to any such request is inaccurate or incomplete, our board of directors may decline to register any transfer or to effect anyissuance or purchase of our common shares to which such request is related.In addition, the insurance holding company laws and regulations of the states in which our insurance companies are domiciled generally require that,before a person can acquire direct or indirect control of an insurer domiciled in the state, and in some cases prior to divesting its control, prior writtenapproval must be obtained from the insurer’s domiciliary state insurance regulator. In addition to insurance holding company laws and regulations, under theOrganizational Permit issued by the California Department of Insurance to Falls Lake Fire and Casualty Company, Falls Lake Fire and Casualty Company, asa new insurer, was required to enter into an agreement with Falls Lake National restricting the transfer of Falls Lake Fire and Casualty Company’s shares for afive-year period commencing January 1, 2016. Specifically, under the agreement, the restriction on share transfer is released automatically without furtherapproval or consent by the California Department of Insurance, or any other party, at the following respective times: 5% at the end of the first year of the 5-year restriction period; an additional 5% at the end of the second year; an additional 10% at the end of the third year; an additional 20% at the end of thefourth year; and the remainder at the end of the fifth year. Therefore, under the Organizational Permit and the Agreement Restricting Shares, Falls LakeNational’s ability to directly or indirectly transfer the shares of Falls Lake Fire and Casualty Company to anyone without the prior written approval of theCalifornia Department of Insurance is limited. These laws and the similar conditions applicable to Falls Lake Fire and Casualty Company’s shares maydiscourage potential acquisition proposals and may delay, deter or prevent an investment in or a change of control involving us, or one or more of ourregulated60TABLE OF CONTENTSsubsidiaries, including transactions that our management and some or all of shareholders might consider desirable. Pursuant to applicable laws andregulations, “control” over an insurer is generally presumed to exist if any person, directly or indirectly, owns, controls, holds the power to vote or holdsproxies representing, 10% or more of the voting securities of that reinsurer or insurer. Indirect ownership includes ownership of the Company’s commonshares.Item 1B.UNRESOLVED STAFF COMMENTSNot applicable.Item 2.PROPERTIESWe lease office space in Bermuda, where our principal executive office is located and our casualty reinsurance segment is based.

Prior to that time, there wasno public market for our common shares. As of February 25, 2019, there were approximately 8 holders of record of our common shares.DividendsWe paid dividends of  $0.30 per share in each quarter of 2018 and 2017. We also paid a special dividend of  $0.50 per share in the fourth quarter of2017. We paid dividends of  $0.20 per share in each of the first three quarters of 2016 and, in the fourth quarter, a $0.30 per share dividend plus a specialdividend of $1.35 per share.We are a holding company that has no substantial operations of our own, and we rely primarily on cash dividends or distributions from our subsidiariesto pay our operating expenses and dividends to shareholders. The payment of dividends by our insurance and reinsurance subsidiaries is limited under thelaws and regulations of their respective domicile. These regulations stipulate the maximum amount of annual dividends or other distributions available toshareholders without prior approval of the relevant regulatory authorities. Additionally, dividends from our U.S. subsidiaries to our U.K. intermediate holdingcompany are generally subject to a 5% withholding tax by the IRS. Under U.K. domestic law, no withholding tax is applied to dividends paid by U.K. taxresident companies. As a result of such regulations, or a change in applicable tax law, we may not be able to pay our operating expenses as they become dueand our payment of future dividends to shareholders may be limited. See “Risk Factors — Risks Related to Ownership of Our Common Shares—We dependupon dividends and distributions from our subsidiaries, and we may be unable to distribute dividends to our shareholders to the extent we do not receivedividends from our subsidiaries,” and “—Dividends paid by our U.S. subsidiaries to James River UK may not be eligible for benefits under the U.S.-U.K.income tax treaty.”The declaration, payment and amount of future dividends is subject to the discretion of our board of directors. Our board of directors will giveconsideration to various risks and uncertainties, including those discussed under the headings “Risk Factors” and “Management’s Discussion and Analysis ofFinancial Condition and Results of Operations” and elsewhere in this Annual Report when determining whether to declare and pay dividends, as well as theamount thereof. Our board of directors may take into account a variety of factors when determining whether to declare any future dividends, including (1) ourfinancial condition, liquidity, results of operations (including our ability to generate cash flow in excess of expenses and our expected or actual net income),retained earnings and collateral and capital requirements, (2) general business conditions, (3) legal, tax and regulatory limitations, (4) contractualprohibitions and other restrictions, (5) the effect of a dividend or dividends upon our financial strength ratings and (6) any other factors that our board ofdirectors deems relevant.Performance GraphThe graph below compares the cumulative total shareholder return of our common shares relative to the cumulative total returns of the Russell 2000index and a selected peer group of seven companies that includes Amerisafe Inc., Argo Group International Holdings Ltd, Kinsale Capital Group Inc., MarkelCorp, Navigators Group Inc., RLI Corp and W. R. Berkley Corp. The companies in the peer group are weighted by market capitalization. The calculation ofcumulative total shareholder return assumes an initial investment of $100 and the reinvestment of all dividends, if any, for the period from December 12,2014 (the date of our initial public offering) through December 31, 2018. Such returns are based on historical results and are not intended to suggest futureperformance.62TABLE OF CONTENTS 12/12/2014 12/14 12/15 12/16 12/17 12/18James River Group Holdings, Ltd. 100.00 107.11 166.93 219.56 220.59 207.89Russell 2000 100.00 104.65 100.03 121.34 139.11 123.79Peer Group 100.00 101.78 123.89 139.82 159.20 163.62The performance graph and related information shall not be deemed “soliciting material” or to be “filed” with the SEC for purposes of Section 18 of theSecurities Exchange Act of 1934, as amended, or the Exchange Act, or otherwise subject to the liabilities under that Section, and shall not be deemed to beincorporated by reference into any future filing under the Securities Act of 1933, as amended, or the Exchange Act, except to the extent that we specificallyincorporate it by reference into such filing.63TABLE OF CONTENTSItem 6.SELECTED FINANCIAL DATA​The following tables present selected historical financial information of James River Group Holdings, Ltd. derived from our consolidated balance sheetsas of December 31, 2018, 2017, 2016, 2015 and 2014, and the related consolidated statements of income and comprehensive income, changes inshareholders’ equity and cash flows for each of the five years in the period ended December 31, 2018, which have been audited by Ernst & Young LLP.You should read this selected financial data along with the consolidated financial statements and accompanying notes included elsewhere in thisAnnual Report, as well as the section of this Annual Report titled “Management’s Discussion and Analysis of Financial Condition and Results ofOperations.” Year Ended December 31, 2018 2017 2016 2015 2014 ($ in thousands, except for per share data)Operating Results: Gross written premiums(1) $1,166,773 $1,081,905 $737,398 $572,194 $518,767Ceded written premiums(2) (404,101) (315,279) (179,690) (101,162) (68,684)Net written premiums $762,672 $766,626 $557,708 $471,032 $450,083Net earned premiums $815,398 $741,109 $515,663 $461,205 $396,212Net investment income 61,256 61,119 52,638 44,835 43,005Net realized investment (losses) gains (5,479) (1,989) 7,565 (4,547) (1,336)Other income 14,424 17,386 10,361 3,428 1,122Total revenues 885,599 817,625 586,227 504,921 439,003Losses and loss adjustment expenses 600,276 555,377 325,421 279,016 237,368Other operating expenses 201,035 196,993 170,828 157,803 133,055Other expenses 1,300 539 1,590 730 16,012Interest expense 11,553 8,974 8,448 6,999 6,347Amortization of intangible assets 597 597 597 597 597Total expenses 814,761 762,480 506,884 445,145 393,379Income before income tax expense 70,838 55,145 79,343 59,776 45,624Income tax expense 7,008 11,579 4,872 6,279 939Net income $63,830 $43,566 $74,471 $53,497 $44,685Adjusted net operating income(4) $70,596 $47,385 $71,318 $61,090 $58,424Per share data: Basic earnings per share $2.14 $1.48 $2.56 $1.87 $1.57Diluted earnings per share $2.11 $1.44 $2.49 $1.82 $1.55Dividends declared per share $1.20 $1.70 $2.25 $1.64 $2.45Weighted — average shares outstanding — diluted 30,307,101 30,273,149 29,894,378 29,334,918 28,810,30164TABLE OF CONTENTS At or for the Year Ended December 31, 2018 2017 2016 2015 2014 ($ in thousands, except for per share amounts and ratios)Balance Sheet Data: Cash and invested assets $1,850,303 $1,611,149 $1,442,114 $1,350,697 $1,310,628Reinsurance recoverables 485,715 313,816 185,614 143,086 128,979Goodwill and intangible assets 219,368 220,165 220,762 221,359 221,956Total assets 3,136,776 2,756,695 2,346,533 2,055,497 1,959,292Reserve for losses and loss adjustment expenses 1,661,459 1,292,349 943,865 785,322 716,296Unearned premiums 386,473 418,114 390,563 301,104 277,579Senior debt 118,300 98,300 88,300 88,300 88,300Junior subordinated debt 104,055 104,055 104,055 104,055 104,055Total liabilities 2,427,535 2,061,996 1,653,312 1,374,459 1,271,371Total stockholders’ equity 709,241 694,699 693,221 681,038 687,921GAAP Underwriting Ratios: Loss ratio(5) 73.6% 74.9% 63.1% 60.5% 59.9%Expense ratio(6) 23.0% 24.3% 31.2% 33.5% 33.4%Combined ratio(7) 96.6% 99.2% 94.3% 94.0% 93.3%Other Data: Tangible equity(8) $489,873 $474,534 $472,459 $459,679 $465,965Tangible equity per common share outstanding $16.34 $15.98 $16.15 $15.88 $16.33Debt to total capitalization ratio(9) 23.9% 22.6% 21.7% 22.0% 21.9%Regulatory capital and surplus(10) $681,161 $628,877 $605,298 $601,436 $593,580Net written premiums to surplus ratio(3) 1.1x 1.2x 0.9x 0.8x 0.8x (1)The amount received or to be received for insurance policies written or assumed by us during a specific period of time without reduction for acquisitioncosts, reinsurance costs or other deductions.​(2)The amount of written premiums ceded to (reinsured by) other insurers.​(3)We believe this measure is useful in evaluating our insurance subsidiaries’ operating leverage.

You should read thisdiscussion and analysis together with our audited consolidated financial statements and related notes included elsewhere in this Form 10-K.OverviewJames River Group Holdings, Ltd. is a Bermuda-based holding company. We own and operate a group of specialty insurance and reinsurance companieswith the objective of generating compelling returns on tangible equity while limiting underwriting and investment volatility. We seek to accomplish this byconsistently earning profits from insurance and reinsurance underwriting and generating meaningful risk-adjusted investment returns, while managing ourcapital opportunistically.For the year ended December 31, 2018, approximately 67.6% of our group-wide gross written premiums originated from the U.S. E&S lines marketincluding business assumed by our Casualty Reinsurance segment. We also have a specialty admitted insurance business in the United States. We intend toconcentrate substantially all of our underwriting in casualty insurance and reinsurance, and for the year ended December 31, 2018, we derived 98.5% of ourgroup-wide gross written premiums from casualty insurance and reinsurance. We focus on writing business in specialty markets where our underwriters haveparticular expertise and where we have long-standing distribution relationships; maintaining a strong balance sheet with appropriate reserves; monitoringreinsurance recoverables carefully; managing our investment portfolio actively without taking undue risk; using technology to monitor trends in ourbusiness; responding rapidly to market opportunities and challenges; and actively managing our capital.We report our business in four segments: Excess and Surplus Lines, Specialty Admitted Insurance, Casualty Reinsurance and Corporate and Other.The Excess and Surplus Lines segment offers E&S commercial lines liability and property insurance in every U.S. state and the District of Columbiathrough James River Insurance and its wholly-owned subsidiary, James River Casualty. James River Insurance and James River Casualty are both non-admitted carriers. Non-admitted carriers writing in the E&S market are not bound by most of the rate and form regulations imposed on standard marketcompanies, allowing them flexibility to change the coverage terms offered and the rate charged without the time constraints and financial costs associatedwith the rate and form filing process. In 2018, the average account in this segment (excluding commercial auto policies) generated annual gross writtenpremiums of approximately $20,000. The Excess and Surplus Lines segment distributes primarily through wholesale insurance brokers. Members of ourmanagement team have participated in this market for over three decades and have long-standing relationships with the wholesale agents who place E&Slines accounts. The Excess and Surplus Lines segment produced 56.3% of our gross written premiums and 74.9% of our net written premiums for the yearended December 31, 2018.The Specialty Admitted Insurance segment focuses on niche classes within the standard insurance markets, such as workers’ compensation coverage forbuilding trades, healthcare employees, goods and services, manufacturing, specialty transportation, and agriculture, and on the fronting and programbusiness. In our fronting business, we retain a small percentage of the risk and seek to earn fee income by allowing other carriers and producers to use ourlicensure, ratings, and infrastructure. Given market conditions and availability of reinsurance for program opportunities, we began de-emphasizing programbusiness in 2017. Through Falls Lake National and its subsidiaries, this segment has admitted licenses in 49 states and the District of Columbia anddistributes through a variety of sources, including independent retail agents, program administrators and MGAs. The Specialty Admitted Insurance segmentproduced 32.1% of our gross written premiums and 7.3% of our net written premiums for the year ended December 31, 2018.The Casualty Reinsurance segment provides proportional and working layer casualty reinsurance to third parties and to our U.S.-based insurancesubsidiaries. Typically, we structure our reinsurance contracts (also known as treaties) as quota share arrangements, with loss mitigating features, such ascommissions that adjust based on underwriting results. We frequently include risk mitigating features in our working layer excess of loss treaties, such as paidreinstatements, which allow the ceding company to capture a greater percentage of the profits should the business prove more profitable than expected, oralternatively, with additional premiums should the business incur higher than expected losses. We believe these structures best align our interests with theinterests of our cedents. On a premium volume basis, treaties with loss mitigation features including sliding scale ceding commissions represented 81.7% ofthe gross premiums written by our Casualty Reinsurance segment during 2018. We typically do not assume large individual risks in our CasualtyReinsurance segment, nor do we write property catastrophe reinsurance. Most of the policies assumed by our Casualty Reinsurance segment have a $1.0million per occurrence limit, and we typically assume only a portion of that exposure. We believe this structure reduces volatility in our underwriting results.We do not assume stand-alone third-party property business at our Casualty Reinsurance segment, but we do have a small amount67TABLE OF CONTENTSof assumed business with ancillary property exposure. 83.7% of premiums written by our Casualty Reinsurance segment during 2018 were general liabilityaccounts assumed from E&S carriers. The Casualty Reinsurance segment distributes through reinsurance brokers. The Casualty Reinsurance segmentproduced 11.6% of our gross written premiums and 17.8% of our net written premiums for the year ended December 31, 2018.The Casualty Reinsurance segment writes business through two entities, JRG Re and Carolina Re. Through December 31, 2017, we had intercompanyreinsurance agreements under which we ceded 70% of the net written premiums of our U.S. subsidiaries (after taking into account third-party reinsurance) toJRG Re. Effective January 1, 2018, we generally discontinued ceding 70% of our U.S.-written premiums to JRG Re and instead ceded 70% of our U.S.-writtenpremiums to Carolina Re. This business is ceded under proportional, or quota-share, reinsurance treaties that provide for an arm’s length ceding commission.We exclude the effects of intercompany reinsurance agreements from the presentation of our segment results, consistent with the way we manage theCompany. At December 31, 2018, 54.9% of our cash and invested assets were held at JRG Re, which benefits from a favorable operating environment,including an absence of corporate income or investment taxes.On December 22, 2017, the United States enacted Public Law No. 115-97, informally titled the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Actsignificantly changed the U.S. Internal Revenue Code of 1986, as amended (the “Code”), including by reducing the U.S. corporate income tax rate from 35%to 21% and imposing a base erosion and anti-abuse tax (“BEAT”). In response to the Tax Act, we made changes to our structure in 2018 to minimize theimpact of BEAT that included the formation of Carolina Re, a Bermuda-domiciled, wholly-owned subsidiary of James River Group, Inc. Carolina Re is aClass 3A reinsurer and made an irrevocable election to be taxed as a U.S. domestic corporation under Section 953(d) of the Code effective January 1, 2018.Carolina Re is also the cedent on a stop loss reinsurance treaty with JRG Re.The Corporate and Other segment consists of the management and treasury activities of our holding companies and interest expense associated with ourdebt.The A.M. Best financial strength rating for our group’s regulated insurance subsidiaries is “A” (Excellent). This rating reflects A.M. Best’s opinion of ourinsurance subsidiaries’ financial strength, operating performance and ability to meet obligations to policyholders and is not an evaluation directed towardsthe protection of investors.Critical Accounting Policies and EstimatesWe identified the accounting estimates below as critical to the understanding of our financial position and results of operations. Critical accountingestimates are defined as those estimates that are both important to the portrayal of our financial condition and results of operations and which require us toexercise significant judgment. We use significant judgment concerning future results and developments in applying these critical accounting estimates andin preparing our consolidated financial statements. These judgments and estimates affect the reported amounts of assets, liabilities, revenues and expensesand the disclosure of material contingent assets and liabilities. Actual results may differ materially from the estimates and assumptions used in preparing theconsolidated financial statements. We evaluate our estimates regularly using information that we believe to be relevant. For a detailed discussion of ouraccounting policies, see the Notes to Consolidated Financial Statements included in this Form 10-K.Reserve for Losses and Loss Adjustment ExpensesThe reserve for losses and loss adjustment expenses represents our estimated ultimate cost of all reported and unreported losses and loss adjustmentexpenses incurred and unpaid at the balance sheet date. We do not discount this reserve. We estimate the reserve using individual case-basis valuations ofreported claims and statistical analysis. We believe that the use of judgment is necessary to arrive at a best estimate for the reserve for losses and lossadjustment expenses given the long-tailed nature of the business we write and the limited operating experience of the Casualty Reinsurance segment and ofthe fronting and program business in the Specialty Admitted Insurance segment and the commercial auto business in our Excess and Surplus lines segment. Inapplying this judgment, we frequently establish reserves that differ from our internal actuaries’ estimate. We seek to establish reserves that will ultimatelyprove to be adequate. If we have indications that claims frequency or severity exceeds our initial expectations, we generally increase our reserves for lossesand loss adjustment expenses. Conversely, when claims frequency and severity trends are more favorable than initially anticipated, we generally reduce ourreserves for losses and loss adjustment expenses once we have sufficient data to confirm the validity of the favorable trends.Our Excess and Surplus Lines and Specialty Admitted Insurance segments generally are notified of losses by our insureds or their brokers. Based on theinformation provided, we establish case reserves by estimating the ultimate losses from the claim, including administrative costs associated with the ultimatesettlement of the claim. Our claims department personnel use their knowledge of the specific claim along with internal and external experts, includingunderwriters and legal counsel, to estimate the expected ultimate losses.Our Casualty Reinsurance segment generally establishes case reserves based on reports received from ceding companies or their brokers. For excess ofloss contracts, we are typically notified of insurance losses on specific contracts, and we record68TABLE OF CONTENTScase reserves based on the estimated ultimate losses on each claim. For proportional contracts, we typically receive aggregated claims information and recordcase reserves based on that information.We also use statistical analysis to estimate the cost of losses and loss adjustment expenses that have been incurred but not reported to us. Thoseestimates are based on our historical information, industry information and estimates of future trends that may affect the frequency of claims and changes inthe average cost of claims (severity) that may arise in the future.The Company’s gross reserve for losses and loss adjustment expenses at December 31, 2018 was $1,661.5 million. Of this amount, 62.4% relates toIBNR. The Company’s gross reserve for losses and loss adjustment expenses by segment are summarized as follows: Gross Reserves at December 31, 2018 Case IBNR Total IBNR %of Total ($ in thousands)Excess and Surplus Lines $352,015 $608,548 $960,563 63.4%Specialty Admitted Insurance 161,916 264,399 426,315 62.0%Casualty Reinsurance 110,339 164,242 274,581 59.8%Total $624,270 $1,037,189 $1,661,459 62.4%The Company’s net reserve for losses and loss adjustment expenses at December 31, 2018 was $1,194.1 million.

The ReserveCommittee meets quarterly to review the actuarial recommendations made by each chief actuary and uses its best judgment to determine the best estimate tobe recorded for the reserve for losses and loss adjustment expenses on our balance sheet. The Reserve Committee believes that using judgment to supplementthe actuarial recommendations is necessary to arrive at a best estimate given the nature of the business that we write and the limited operating experience ofthe Casualty Reinsurance segment, the fronting and program business in the Specialty Admitted Insurance segment and the commercial auto underwritingdivision in the Excess and Surplus Lines segment.The process of estimating the reserve for losses and loss adjustment expenses requires a high degree of judgment and is subject to a number of variables.In establishing the quarterly actuarial recommendation for the reserve for losses and loss adjustment expenses, our internal actuaries estimate an initialexpected ultimate loss ratio for each of our product lines by accident year (or for our Casualty Reinsurance segment, on a contract by contract basis). Inputfrom our underwriting and claims departments, including premium pricing assumptions and historical experience, are considered by our internal actuaries inestimating the initial expected loss ratios. Our actuaries generally utilize five actuarial methods in their estimation process for the reserve for losses and lossadjustment expenses. These five methods utilize, to varying degrees, the initial expected loss ratio, detailed statistical analysis of past claims reporting andpayment patterns, claims frequency and severity, paid loss experience, industry loss experience, and changes in market conditions, policy forms, exclusions,and exposures. The five actuarial methods that we use in our reserve estimation process are:Expected Loss MethodThe Expected Loss method multiplies earned premiums by an initial expected loss ratio.69TABLE OF CONTENTSIncurred Loss Development MethodThe Incurred Loss Development method uses historical loss reporting patterns to estimate future loss reporting patterns. In this method, our actuariesapply historical loss reporting patterns to develop incurred loss development factors that are applied to current reported losses to calculate expected ultimatelosses.Paid Loss Development MethodThe Paid Loss Development method is similar to the Incurred Loss Development method, but it uses historical loss payment patterns to estimate futureloss payment patterns. In this method, our actuaries apply historical loss payment patterns to develop paid loss development factors that are applied tocurrent paid losses to calculate expected ultimate losses.Bornhuetter-Ferguson Incurred Loss Development MethodThe Bornhuetter-Ferguson Incurred Loss Development method divides the projection of ultimate losses into the portion that has already been reportedand the portion that has yet to be reported. The portion that has yet to be reported is estimated as the product of premiums earned for the accident year, theinitial expected ultimate loss ratio and an estimate of the percentage of ultimate losses that are unreported at the valuation date.Bornhuetter-Ferguson Paid Loss Development MethodThe Bornhuetter-Ferguson Paid Loss Development method is similar to the Bornhuetter-Ferguson Incurred Loss Development method, except thismethod divides the projection of ultimate losses into the portion that has already been paid and the portion that has yet to be paid. The portion that has yet tobe paid is estimated as the product of premiums earned for the accident year, the initial expected ultimate loss ratio and an estimate of the percentage ofultimate losses that are unpaid at the valuation date.Different reserving methods are appropriate in different situations, and our actuaries use their judgment and experience to determine the weighting of themethods detailed above to use for each accident year and each line of business and, for our Casualty Reinsurance segment, on a contract by contract basis.For example, the current accident year has very little incurred and paid loss development data on which to base reserve projections. As a result, we relyheavily on the Expected Loss Method in estimating reserves for the current accident year. We generally set our initial expected loss ratio for the currentaccident year consistent with our pricing assumptions. We believe that this is a reasonable and appropriate reserving assumption for the current accident yearsince our pricing assumptions are actuarially driven and since we expect to make an acceptable return on the new business that we write. If actual lossemergence is better than our initial expected loss ratio assumptions, we will experience favorable development, and if it is worse than our initial expectedloss ratio assumptions, we will experience adverse development. Conversely, sufficient incurred and paid loss development is available for our oldestaccident years, so more weight is given to the Incurred Loss Development method and the Paid Loss Development method than the Expected Loss method.The Bornhuetter-Ferguson Incurred Loss Development and Paid Loss Development methods blend features of the Expected Loss method and the Incurredand Paid Loss Development methods. The Bornhuetter-Ferguson methods are typically used for the more recent prior accident years.In applying these methods to develop an estimate of the reserve for losses and loss adjustment expenses, our internal actuaries use judgment todetermine three key parameters for each accident year and line of business: the initial expected loss ratios, the incurred and paid loss development factors andthe weighting of the five actuarial methods to be used for each accident year and line of business. For the Excess and Surplus Lines and Specialty AdmittedInsurance segments, the actuary performs a study on each of these parameters annually and makes recommendations for the initial expected loss ratios, theincurred and paid loss development factors and the weighting of the five actuarial methods by accident year and line of business. Members of the ReserveCommittee review and approve the parameter review actuarial recommendations, and these approved parameters are used in the reserve estimation process forthe next four quarters at which time a new parameter study is performed. For the Casualty Reinsurance segment, periodic assessments are made on a contractby contract basis with the goal of keeping the initial expected loss ratios and the incurred and paid loss development factors as constant as possible untilsufficient evidence presents itself to support adjustments. Method weights are generally less rigid for the Casualty Reinsurance segment given theheterogeneous nature of the various contracts, and the potential for significant changes in mix of business within individual treaties.We engage an independent internationally recognized actuarial consulting firm to review our reserves for losses and loss adjustment expenses twiceeach year, once prior to closing the third quarter and once for the closing of the fourth quarter. This independent actuarial consulting firm prepares its ownestimate of our reserve for loss and loss adjustment expenses, and we compare their estimate to the reserve for losses and loss adjustment expenses reviewedand approved by the Reserve Committee in order to gain additional comfort on the adequacy of our reserves.The table below quantifies the impact of extreme reserve deviations from our expected value at December 31, 2018. The total carried net reserve forlosses and loss adjustment expenses is displayed alongside 5th, 50th and 95th percentiles of likely70TABLE OF CONTENTSultimate net reserve outcomes. The estimates of these percentiles are a result of a reserve variability analysis using a simulation approach.Sensitivity 5th Pct. 50th Pct. Carried 95th Pct. (in thousands)Reserve for losses and loss adjustment expenses $1,061,245 $1,191,249 $1,194,088 $1,337,509Changes in reserves (132,843) (2,839) — 143,421The impact of recording the net reserve for losses and loss adjustment expenses at the highest value from the sensitivity analysis above would be toincrease losses and loss adjustment expenses incurred by $143.4 million, reduce after-tax net income by $133.0 million, reduce shareholders’ equity by$133.0 million and reduce shareholders’ tangible equity by $133.0 million, in each case at or for the period ended December 31, 2018.The impact of recording the net reserve for losses and loss adjustment expenses at the lowest value from the sensitivity analysis above would be toreduce losses and loss adjustment expenses incurred by $132.8 million, increase after-tax net income by $123.2 million, increase shareholders’ equity by$123.2 million, and increase tangible equity by $123.2 million, in each case at or for the year ended December 31, 2018. Such changes in the net reserve forlosses and loss adjustment expenses would not have an immediate impact on our liquidity, but would affect cash flow and investment income in futureperiods as the incremental or reduced amount of losses are paid and investment assets adjusted to reflect the level of paid claims.Loss reserve estimates are subject to a high degree of variability due to the inherent uncertainty of ultimate claims settlement values. In recording ourbest estimate of our reserve for losses and loss adjustment expenses, our Reserve Committee typically selects an amount above the actuarial recommendationdue to the inherent variation associated with our reserve estimates and the likelihood that there are unforeseen or under-valued liabilities in the actuarialrecommendations. We believe that the insurance that we write is subject to above-average variation in reserve estimates. The Excess and Surplus Linesmarket is subject to high policyholder turnover and changes in underlying mix of exposures. This turnover and change in underlying mix of exposures cancause actuarial estimates based on prior experience to be less reliable than estimates for more stable, admitted books of business. As a casualty insurer, losseson our policies often take a number of years to develop, making it difficult to estimate the ultimate losses associated with this business. Judicial andregulatory bodies have frequently interpreted insurance contracts in a manner that expands coverage beyond that which was contemplated at the time that thepolicy was issued. In addition, many of our policies are issued on an occurrence basis, and insureds suffering a loss frequently seek coverage beyond thepolicies’ original intent. The difficulty in pinpointing actual ultimate losses and loss adjustment expenses (“LAE”) is illustrated by the fact that atDecember 31, 2018, 61.6% of our net reserve for losses and loss adjustment expenses in the Excess and Surplus Lines segment is for claims that have not beenreported.Our reserves are driven by a number of important assumptions, including litigation and regulatory trends, legislative activity, climate change, social andeconomic patterns and claims inflation assumptions. Our reserve estimates reflect current inflation in legal claims’ settlements and assume we will not besubject to losses from significant new legal liability theories. Our reserve estimates also assume that we will not experience significant losses from mass tortsand that we will not incur losses from future mass torts not known to us today. While it is not possible to predict the impact of changes in the litigationenvironment, if new mass torts or expanded legal theories of liability emerge, our cost of claims may differ substantially from our reserves. Our reserveestimates assume that there will not be significant changes in the regulatory and legislative environment. The impact of potential changes in the regulatory orlegislative environment is difficult to quantify in the absence of specific, significant new regulation or legislation. In the event of significant new regulationor legislation, we will attempt to quantify its impact on our business but no assurance can be given that our attempt to quantify such inputs will be accurateor successful.IBNR reserve estimates are inherently less precise than case reserve estimates. A 5% change in net IBNR reserves at December 31, 2018 would equate toa $36.7 million change in the reserve for losses and loss adjustment expenses at such date, a $32.6 million change in after-tax net income, a 4.6% change inshareholders’ equity and a 6.6% change in tangible equity, in each case at or for the year ended December 31, 2018.Although we believe that our reserve estimates are reasonable, it is possible that our actual loss experience may not conform to our assumptions.Specifically, our actual ultimate loss ratio could differ from our initial expected loss ratio or our actual reporting and payment patterns could differ from ourexpected reporting and payment patterns, which are based on our own data and industry data. Accordingly, the ultimate settlement of losses and the relatedloss adjustment expenses may vary significantly from the estimates included in our financial statements. We regularly review our estimates and adjust themas necessary as experience develops or as new information becomes known to us. Such adjustments are included in current operations.71TABLE OF CONTENTS$17.7 million of adverse development was experienced in 2018 on the reserve for losses and loss adjustment expenses held at December 31, 2017. Thisadverse reserve development included $15.0 million of adverse development in the Excess and Surplus Lines segment, including $20.7 million of adversedevelopment in the commercial auto line of business that was primarily related to the 2016 contract year with one insured. The adverse development forcommercial auto was partially offset by $5.7 million of favorable development in other Excess and Surplus Lines underwriting divisions primarily fromfavorable development in the Excess Property underwriting division related to the 2017 hurricanes. Favorable reserve development in the Specialty AdmittedInsurance segment was $5.6 million and primarily came from accident years 2014 through 2016, as loss emergence on our workers’ compensation businesswritten prior to 2016 continued to develop more favorably than we had anticipated. In addition, $8.2 million of adverse development occurred in theCasualty Reinsurance segment, with a majority of this adverse development coming primarily from accident years at least four years old and in treaties theCompany has since non-renewed.$21.5 million of adverse development was experienced in 2017 on the reserve for losses and loss adjustment expenses held at December 31, 2016. Thisadverse reserve development included $20.0 million of adverse development in the Excess and Surplus Lines segment, including $38.7 million of adversedevelopment in the commercial auto line of business that was primarily related to the 2016 contract year with one insured. The adverse development forcommercial auto was partially offset by favorable development of $18.6 million in other Excess and Surplus Lines underwriting divisions primarily from the2014 through 2016 accident years. This favorable development occurred because our actuarial studies at December 31, 2017 for the Excess and Surplus Linessegment indicated that our loss experience on our casualty business excluding commercial auto continued to be below our initial expected ultimate lossratios. The Company also experienced $2.7 million of favorable development on prior accident years in the Specialty Admitted Insurance segment primarilyfrom accident years 2010 through 2015, as losses on our workers’ compensation business written prior to 2016 continued to develop more favorably than wehad anticipated. The Casualty Reinsurance segment experienced $4.2 million of adverse development on prior accident years primarily from two contractsfrom 2010 through 2013 that had higher than expected reported losses in 2017.A $23.7 million redundancy developed in 2016 on the reserve for losses and loss adjustment expenses held at December 31, 2015. This favorable reservedevelopment included $24.1 million of favorable development in the Excess and Surplus Lines segment. The Excess and Surplus Lines segment favorabledevelopment included $10.0 million of favorable development from the 2015 accident year, $10.7 million of favorable development from the 2014 accidentyear and $4.5 million from the 2013 accident year. This favorable development occurred because our actuarial studies at December 31, 2016 showed that theexperience on our casualty business continued to be below our initial expected ultimate loss ratios driven by favorable calendar year emergence. Favorablereserve development in the Specialty Admitted Insurance segment was $3.8 million, and primarily came from accident years 2010 through 2014, as losses onour workers’ compensation business written prior to 2015 continued to develop more favorably than we had anticipated. The Specialty Admitted Insurancesegment’s favorable development from accident years 2010 – 2014 was partially offset by unfavorable development for the 2015 accident year. In addition,$4.2 million of adverse development occurred in the Casualty Reinsurance segment, with the majority of this adverse development coming from twocontracts from the 2012 and 2013 underwriting years that experienced higher loss development in 2016 than expected.Investment Valuation and ImpairmentWe carry fixed maturity securities classified as “available-for-sale” at fair value, and unrealized gains and losses on such securities, net of any deferredtaxes, are reported as a separate component of accumulated other comprehensive income. Equity securities (except those accounted for under the equitymethod of accounting or those that result in consolidation of the investee) are measured at fair value with changes in fair value recognized in net income.Fixed maturity securities purchased for short-term resale are classified as “trading” and are carried at fair value with unrealized gains and losses included inearnings as a component of investment income. We do not have any securities classified as “held-to-maturity.”We evaluate our available-for-sale fixed maturity securities regularly to determine whether there have been declines in value that are other-than-temporary. Our outside investment managers assist us in this evaluation. When we determine that a security has experienced an other-than-temporaryimpairment, the impairment loss is recognized as a realized investment loss.We consider a number of factors in assessing whether an impairment is other-than-temporary, including (1) the amount and percentage that current fairvalue is below amortized cost, (2) the length of time that the fair value has been below amortized cost and (3) recent corporate developments or other factorsthat may impact an issuer’s near term prospects. In addition, we consider the credit quality ratings for the securities, with a special emphasis on securitiesdowngraded to below investment grade. We also consider our intent to sell available-for-sale fixed maturity securities in an unrealized loss position, and if itis “more likely than not” that we will be required to sell these securities before a recovery in fair value to their amortized cost basis. As a starting point for ourevaluation, we compare the fair value of each available-for-sale security to its amortized cost to identify any securities with a fair value less than amortizedcost.72TABLE OF CONTENTSManagement concluded that none of the fixed maturity securities with an unrealized loss at December 31, 2018, 2017, and 2016 experienced an other-than-temporary impairment. Management does not intend to sell available-for-sale securities in an unrealized loss position, and it is not “more likely thannot” that the Company will be required to sell these securities before a recovery in their value to their amortized cost basis occurs.Effective January 1, 2018, with the adoption of ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement ofFinancial Assets and Financial Liabilities, equity securities (except those accounted for under the equity method of accounting or those that result inconsolidation of the investee) are measured at fair value with changes in fair value recognized in net investment income. Prior to the adoption of ASU 2016-01, changes in the fair value of equity securities were recognized net of taxes as a component of accumulated other comprehensive income.At December 31, 2017, management concluded that one equity security, based on the severity and duration of the impairment, had experienced an other-than-temporary impairment. Accordingly, the Company recorded an impairment loss of $1.5 million in 2017. Management concluded that none of the otherequity securities with an unrealized loss at December 31, 2017 and 2016 experienced an other-than-temporary impairment. Management evaluated the near-term prospects of these other equity securities in relation to the severity and duration of the impairment, and management had the ability and intent to holdthe securities until a recovery of their fair value.Bank loan participations held-for-investment are managed by a specialized outside investment manager and are generally stated at their outstandingunpaid principal balances net of unamortized premiums or discounts and net of any allowance for credit losses.We maintain the allowance for credit losses at a level we believe is adequate to absorb estimated probable credit losses. Our periodic evaluation of theadequacy of the allowance is based on consultations and the advice of our specialized investment manager, known and inherent risks in the portfolio, adversesituations that may affect the borrowers’ ability to repay, the estimated value of any underlying collateral, current economic conditions and other relevantfactors. The Company has recorded an allowance equal to the difference between the fair value and the amortized cost of bank loans that it has determined tobe impaired as a practical expedient for an estimate of probable future cash flows to be collected on those bank loans. As a starting point for our evaluation,we compare the carrying value of each loan to its fair value to identify any loans that had a fair value less than its carrying value.At December 31, 2017 and 2016, the Company held a participation in a loan issued by a company that produces and supplies power to Puerto Ricothrough a power purchase agreement with Puerto Rico Electric Power Authority (“PREPA”), a public corporation and governmental agency of theCommonwealth of Puerto Rico. Management concluded that the loan was impaired and established credit allowances on the loan of $759,000 and $177,000at December 31, 2017 and 2016, respectively. At December 31, 2017, the loan had a carrying value of zero and unpaid principal of $807,000. In the firstquarter of 2018, the full outstanding principal on the loan was repaid and the Company recognized a realized gain of $807,000 on the repayment.Management concluded that none of the loans in the Company's bank loan portfolio were impaired as of December 31, 2018. At December 31, 2017, theaggregate allowance for credit losses was $3.2 million on five impaired loans with a total carrying value of $5.1 million and unpaid principal of $8.4 million.Impairments in the bank loan portfolio at December 31, 2017 largely reflected the impact of declining energy prices on the market values of loans to oil andgas companies in the energy sector at that time.Fair values are measured in accordance with ASC 820, Fair Value Measurements. The guidance establishes a framework for measuring fair value and athree-level hierarchy based upon the quality of inputs used to measure fair value. The three levels of the fair value hierarchy are: (1) Level 1: quoted price(unadjusted) in active markets for identical assets, (2) Level 2: inputs to the valuation methodology include quoted prices for similar assets and liabilities inactive markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the instrument and (3)Level 3: inputs to the valuation methodology are unobservable for the asset or liability.The fair values of fixed maturity securities and equity securities have been determined using fair value prices provided by our investment manager, whoutilizes internationally recognized independent pricing services. The prices provided by the independent pricing services are generally based on observablemarket data in active markets (e.g. broker quotes and prices observed for comparable securities). Values for U.S. Treasury and publicly-traded equitysecurities are generally based on Level 1 inputs which use the market approach valuation technique. The values for all other fixed maturity securities(including state and municipal securities and obligations of U.S. government corporations and agencies) generally incorporate significant Level 2 inputs, andin some cases, Level 3 inputs, using the market approach and income approach valuation techniques.The fair values of cash and cash equivalents and short-term investments approximate their carrying values due to their short-term maturity.In the determination of the fair value for bank loan participations and certain high yield bonds, the Company’s investment manager endeavors to obtaindata from multiple external pricing sources. External pricing sources may include brokers,73TABLE OF CONTENTSdealers, and price data vendors that provide a composite price based on prices from multiple dealers. Such external pricing sources typically providevaluations for normal institutional size trading units of such securities using methods based on market transactions for comparable securities, and variousrelationships between securities, as generally recognized by institutional dealers. For investments in which the investment manager determines that only oneexternal pricing source is appropriate or if only one external price is available, the investment is generally recorded based on such price.Investments for which external sources are not available or are determined by the investment manager not to be representative of fair value are recordedat fair value as determined by the investment manager. In determining the fair value of such investments, the investment manager considers one or more ofthe following factors: type of security held, convertibility or exchangeability of the security, redeemability of the security (including the timing ofredemptions), application of industry accepted valuation models, recent trading activity, liquidity, estimates of liquidation value, purchase cost and pricesreceived for securities with similar terms of the same issuer or similar issuers. At December 31, 2017, there was a bank loan participation with an unpaidprincipal balance of $807,000 and a carrying value of $0 for which external sources were unavailable to determine fair value. There were no bank loanparticipations for which external sources were unavailable to determine fair value at December 31, 2018.We review fair value prices provided by our outside investment managers for reasonableness by comparing the fair values provided by the managers tothose provided by our investment custodian. We also review and monitor changes in unrealized gains and losses. We obtain an understanding of themethods, models, and inputs used by our investment managers and independent pricing services, and controls are in place to validate that prices providedrepresent fair values. Our control process includes, but is not limited to, initial and ongoing evaluation of the methodologies used, a review of specificsecurities and an assessment for proper classification within the fair value hierarchy, and obtaining and reviewing internal control reports for our investmentmanager that obtains fair values from independent pricing services.Assumed Reinsurance PremiumsAssumed reinsurance written premiums include amounts reported by brokers and ceding companies, supplemented by the Company’s own estimates ofpremiums when reports have not been received. Premiums on the Company’s excess of loss and pro rata reinsurance contracts are estimated when the businessis underwritten. For excess of loss contracts, the deposit premium, as defined in the contract, is generally recorded as an estimate of premiums written at theinception date of the treaty. Estimates of premiums written under pro rata contracts are recorded in the period in which the underlying risks are expected tobegin and are based on information provided by the brokers and the ceding companies.Reinsurance premium estimates are reviewed by management periodically. Any adjustment to these estimates is recorded in the period in which itbecomes known. The impact of any premium adjustments on net income is offset by corresponding changes to related policy acquisition costs and losses andloss adjustment expenses. For the years ended December 31, 2018, 2017, and 2016, these adjustments were immaterial.Reinsurance premiums assumed are earned over the terms of the underlying policies or reinsurance contracts. Contracts and policies written on a “lossesoccurring” basis cover claims that may occur during the term of the contract or policy, which is typically 12 months. Accordingly, the premiums are earnedevenly over the term. Contracts which are written on a “risks attaching” basis cover claims which attach to the underlying insurance policies written duringthe terms of such contracts. Premiums earned on such contracts usually extend beyond the original term of the reinsurance contract, typically resulting inrecognition of premiums earned over a 24-month period in proportion to the level of underlying exposure.Certain of the Company’s reinsurance contracts include provisions that adjust premiums or acquisition expenses based upon the experience under thecontracts. Premiums written and earned, as well as related acquisition expenses, are recorded based upon the projected experience under the contracts.Recent Accounting PronouncementsEffective January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606).The guidance applies to all companies that either enter into contracts with customers to transfer goods or services or enter into contracts for the transfer ofnonfinancial assets, unless those contracts are within the scope of other standards, such as insurance contracts. Under this guidance, a company will recognizerevenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled inexchange for those goods or services. Judgments required in adopting this update included identifying performance obligations in the contract, estimatingthe amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. Theadoption of ASU 2014-09 had no impact on reported fee income and there was no cumulative effect of initially applying the update.Effective January 1, 2018, the Company adopted ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement ofFinancial Assets and Financial Liabilities. Among other things, this ASU requires equity investments (except those accounted for under the equity methodof accounting or those that result in consolidation of the74TABLE OF CONTENTSinvestee) to be measured at fair value with changes in fair value recognized in net income. Upon adoption on January 1, 2018, the Company made a $4.7million cumulative-effect adjustment to increase retained earnings and reduce accumulated other comprehensive income. The adoption of ASU 2016-01 didnot materially impact the Company's financial position, cash flows, or total comprehensive income. The Company's results of operations were impacted aschanges in fair value of equity instruments are now presented in net income rather than other comprehensive (loss) income. For the year ended December 31,2018, the respective impact on net income was a reduction of $4.7 million ($0.16 reduction in basic and diluted earnings per share).Effective January 1, 2018, the Company adopted ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification ofCertain Tax Effects from Accumulated Other Comprehensive Income. This update was issued as a result of the enactment of the Tax Act on December 22,2017. The ASU allows for the option to reclassify the stranded tax effects resulting from the implementation of the Tax Act out of accumulated othercomprehensive income and into retained earnings. As the adoption of ASU 2016-01 in 2018 resulted in the reclassification of the entire unrealized balanceon equity securities from accumulated other comprehensive income into retained earnings, only the stranded tax effects on the unrealized balances of fixedincome securities were impacted by the adoption of ASU 2018-02. The reclassification resulted in a $711,000 decrease to the Company's retained earningswith a corresponding increase to accumulated other comprehensive income in the first quarter of 2018.In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). Under current guidance for lessees, leases are only included on the balance sheet ifthey are designated as capital leases. This update will require the recognition of a right-of-use asset and a corresponding lease liability, discounted to thepresent value, for all leases that extend beyond 12 months. This ASU is effective for annual and interim reporting periods beginning after December 15, 2018.In the third quarter of 2018, the FASB issued ASU 2018-10 to clarify certain aspects of the guidance and ASU 2018-11, which provides an optionalalternative transition method to initially apply the new leases standard at the adoption date (collectively, with ASU 2016-02, Topic 842). Topic 842 nowallows for the use of either the modified retrospective adoption method or the alternative transition method. The Company has completed its evaluation andwill adopt the new standard on January 1, 2019 using a modified retrospective transition method, applying the transition provisions at the beginning of theperiod of adoption. The Company will elect the package of practical expedients permitted under the transition guidance within the new standard and will notelect to use hindsight in determining the lease term. The new standard will not be applied to leases with an initial term of 12 months or less. Upon adoption ofthe new standard, the Company will derecognize assets of $22.6 million and liabilities of $30.9 million associated with a lease that was designated as build-to-suit under the previous guidance, and record a cumulative-effect adjustment to retained earnings of $8.3 million. The lease will be classified as anoperating lease under the new standard. The Company will record right-of-use assets of $17.2 million and lease liabilities of $17.8 million at adoption of thenew standard. The new standard will not materially impact the Company's results of operations or cash flows, and will not impact compliance under thecovenants of our current credit agreements.In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on FinancialInstruments. Current GAAP delays the recognition of credit losses until it is probable a loss has been incurred. The update will require financial assetsmeasured at amortized cost, such as bank loan participations held for investment, to be presented at the net amount expected to be collected by means of anallowance for credit losses that runs through net income. Credit losses relating to available-for-sale debt securities will also be recorded through an allowancefor credit losses, with the amount of the allowance limited to the amount by which fair value is below amortized cost. This ASU is effective for annual andinterim reporting periods beginning after December 15, 2019. Upon adoption, this ASU will be applied using the modified-retrospective approach, by whicha cumulative-effect adjustment will be made to retained earnings as of the beginning of the first reporting period presented. The Company has not yetcompleted the analysis of how adopting this ASU will affect the Company’s financial statements.75TABLE OF CONTENTSYear Ended December 31, 2018 Compared to Year Ended December 31, 2017The following table summarizes our results for the years ended December 31, 2018 and 2017:Year Ended December 31, 2018 2017 % Change($ in thousands) Gross written premiums$1,166,773 $1,081,905 7.8 %Net retention(1)65.4% 70.9% Net written premiums$762,672 $766,626 (0.5)%Net earned premiums$815,398 $741,109 10.0 %Losses and loss adjustment expenses(600,276) (555,377) 8.1 %Other operating expenses(187,116) (179,968) 4.0 %Underwriting profit (2), (3)28,006 5,764 385.9 %Net investment income61,256 61,119 0.2 %Net realized and unrealized investment losses(5,479) (1,989) 175.5 %Other income and expense(795) (178) 346.6 %Interest expense(11,553) (8,974) 28.7 %Amortization of intangible assets(597) (597) — %Income before taxes70,838 55,145 28.5 %Income tax expense7,008 11,579 (39.5)%Net income$63,830 $43,566 46.5 %Adjusted net operating income (4)$70,596 $47,385 49.0 %Ratios: Loss ratio73.6% 74.9% Expense ratio23.0% 24.3% Combined ratio96.6% 99.2% (1)Net retention is defined as the ratio of net written premiums to gross written premiums.​(2)Underwriting profit is a non-GAAP measure.

See “Reconciliation of Non-GAAP Measures” for reconciliation to net income and foradditional information.We had an underwriting profit of $28.0 million for the year ended December 31, 2018. This compares to an underwriting profit of $5.8 million for theprior year. On a consolidated basis, the Company recognized $17.7 million and $21.5 million of net adverse reserve development for the years endedDecember 31, 2018 and 2017, respectively.The results for the years ended December 31, 2018 and 2017 included certain non-operating items that are significant to the Company. These items (on apre-tax basis) include:•Net realized and unrealized investment losses of $5.5 million and $2.0 million for the years ended December 31, 2018 and 2017, respectively. See “-Investing Results" for more information on these realized and unrealized investment losses.•Interest expense of $1.6 million and $1.3 million for the years ended December 31, 2018 and 2017, respectively, relating to finance expenses inconnection with a minority interest in a real estate partnership pursuant to which we are deemed an owner for accounting purposes. The debt isnonrecourse to us and was not arranged by us.We define adjusted net operating income as net income excluding certain non-operating expenses such as net realized and unrealized investment gainsand losses on investments, expenses related to due diligence costs for various merger and76TABLE OF CONTENTSacquisition activities, professional service fees related to the filing of registration statements for the offering of securities, severance costs associated withterminated employees, and interest expense and other income and expenses on a leased building that we are deemed to own for accounting purposes. We useadjusted net operating income as an internal performance measure in the management of our operations because we believe it gives our management andother users of our financial information useful insight into our results of operations and our underlying business performance. Adjusted net operating incomeshould not be viewed as a substitute for net income calculated in accordance with GAAP, and our definition of adjusted net operating income may not becomparable to that of other companies.Our income before taxes and net income for the years ended December 31, 2018 and 2017 reconcile to our adjusted net operating income as follows:Year Ended December 31,2018 2017IncomeBeforeTaxes Net Income IncomeBeforeTaxes NetIncome(in thousands)Income as reported$70,838 $63,830 $55,145 $43,566Net realized and unrealized losses on investments5,479 4,374 1,989 1,375Other expenses1,100 941 539 575Impairment of intangible assets200 200 — —Dividend withholding taxes— — — 1,053Interest expense on leased building the Company is deemed to ownfor accounting purposes1,584 1,251 1,256 816Adjusted net operating income$79,201 $70,596 $58,929 $47,385Combined RatiosThe combined ratio is a measure of underwriting performance and represents the relationship of incurred losses, loss adjustment expenses and otheroperating expenses to net earned premiums. Our combined ratio for the year ended December 31, 2018 was 96.6%. A combined ratio of less than 100%indicates an underwriting profit, while a combined ratio greater than 100% reflects an underwriting loss. In 2018, the combined ratio included $17.7 million,or 2.2 percentage points, of net adverse reserve development on prior accident years, including $15.0 million of net adverse reserve development from theExcess and Surplus Lines segment (including $4.9 million, or 0.9 percentage points, of favorable reserve development on the 2017 catastrophe losses fromHurricanes Harvey, Irma, and Maria), $5.6 million of net favorable reserve development from the Specialty Admitted Insurance segment, and $8.2 million ofnet adverse reserve development from the Casualty Reinsurance segment.Our combined ratio for the year ended December 31, 2017 was 99.2%. It included $21.5 million, or 2.9 percentage points, of net adverse reservedevelopment on prior accident years, including $20.0 million of net adverse reserve development from the Excess and Surplus Lines segment, $2.7 million ofnet favorable development from the Specialty Admitted Insurance segment, and $4.2 million of net adverse reserve development from the CasualtyReinsurance segment. The combined ratio for the year ended December 31, 2017 also includes $6.9 million, or 0.9 percentage points, of catastrophe lossesfrom Hurricanes Harvey, Irma, and Maria.All of the Company’s U.S.-domiciled insurance subsidiaries are party to an intercompany pooling agreement that distributes the net underwriting resultsamong the group companies based on their approximate pro-rata level of statutory capital and surplus to the total Company statutory capital and surplus.Additionally, each of the Company’s U.S.-domiciled insurance subsidiaries is a party to a quota share reinsurance agreement that in prior periods ceded 70%of their premiums and losses to JRG Re, and starting January 1, 2018, ceded 70% of their premiums and losses to Carolina Re, an entity domiciled inBermuda that made an irrevocable election to be taxed as a U.S. domestic corporation under Section 953(d) of the Code effective January 1, 2018. JRG Realso provides stop loss reinsurance to Carolina Re. We report all segment information in this ‘‘Management’s Discussion and Analysis of Financial Conditionand Results of Operations’’ prior to the effects of intercompany reinsurance, consistent with the manner in which we evaluate the operating performance ofour reportable segments.Expense RatiosOur expense ratio was 23.0% and 24.3% for the years ended December 31, 2018 and 2017, respectively. The improvement is due to a 19.9% increase inthe net earned premiums of the Excess and Surplus Lines segment including in lines of business which carry relatively low expenses or that have meaningfulceding commissions. Our Excess and Surplus Lines segment has77TABLE OF CONTENTSsignificant scale and produces a lower expense ratio than our other operating segments. The Excess and Surplus Lines segment is our largest segment andmakes up 68.1% of consolidated net earned premiums for the year ended December 31, 2018 (62.5% for the year ended December 31, 2017). Gross feeincome for the Company increased from $28.3 million for the year ended December 31, 2017 to $28.7 million for the year ended December 31, 2018.PremiumsInsurance premiums are earned ratably over the terms of our insurance policies, generally twelve months. Reinsurance premiums assumed are earned overthe terms of the underlying policies or reinsurance contracts. Contracts and policies written on a “losses occurring” basis cover claims that may occur duringthe term of the contract or insurance policy, which is typically twelve months. Reinsurance contracts which are written on a “risks attaching” basis coverclaims which attach to the underlying insurance policies written during the terms of such contracts. Premiums earned on such contracts usually extendbeyond the original term of the reinsurance contract, typically resulting in recognition of premiums earned over a 24-month period in proportion to the levelof underlying exposure.The following table summarizes the change in premium volume by component and business segment:Year Ended December 31, 2018 2017 % Change($ in thousands) Gross written premiums: Excess and Surplus Lines$656,538 $530,120 23.8 %Specialty Admitted Insurance374,346 316,430 18.3 %Casualty Reinsurance135,889 235,355 (42.3)%$1,166,773 $1,081,905 7.8 %Net written premiums: Excess and Surplus Lines$571,098 $469,891 21.5 %Specialty Admitted Insurance55,840 60,957 (8.4)%Casualty Reinsurance135,734 235,778 (42.4)%$762,672 $766,626 (0.5)%Net earned premiums: Excess and Surplus Lines$555,684 $463,521 19.9 %Specialty Admitted Insurance55,146 68,110 (19.0)%Casualty Reinsurance204,568 209,478 (2.3)%$815,398 $741,109 10.0 %Gross written premiums for the Excess and Surplus Lines segment (which represents 56.3% of our consolidated gross written premiums in 2018)increased 23.8% over the prior year.

The reduction in gross written premium in this segment was in line with our expectations and is consistent with our plannedreductions for the Casualty Reinsurance segment as we redeploy our capital to where we believe we can make the highest operating returns on tangibleequity. The Casualty Reinsurance segment generally writes large casualty-focused treaties that are expected to have lower volatility relative to property andcatastrophe treaties. We rarely write stand-alone property reinsurance. When treaties that include property exposure are written, we utilize propertyoccurrence caps, inuring reinsurance protection and low individual risk limits to minimize exposure.Net RetentionThe ratio of net written premiums to gross written premiums is referred to as our net premium retention. Our net premium retention by segment is asfollows:Year Ended December 31,2018 2017Excess and Surplus Lines87.0% 88.6%Specialty Admitted Insurance14.9% 19.3%Casualty Reinsurance99.9% 100.2%Total65.4% 70.9%The net premium retention for the Specialty Admitted Insurance segment decreased from 2017 to 2018 as a result of growth in the segment's frontingbusiness, which generally has much lower net premium retention than our workers’ compensation business. Fronting gross written premium grew 17.2% forthe year ended December 31, 2018 compared to the prior year. The net retention on the segment’s fronting business was 9.6% and 11.9% in the years endedDecember 31, 2018 and79TABLE OF CONTENTS2017, respectively, while the net retention on the workers’ compensation business was 45.9% and 64.8%, respectively. The significant decline in the netretention from the prior year on the workers' compensation business is due to the 50% third-party quota share reinsurance coverage purchased in this businesseffective October 1, 2017.Underwriting ResultsThe following table compares our combined ratios by segment:Year Ended December 31,2018 2017Excess and Surplus Lines92.3% 93.6%Specialty Admitted Insurance87.4% 95.4%Casualty Reinsurance97.5% 100.8%Total96.6% 99.2%Excess and Surplus Lines SegmentResults for the Excess and Surplus Lines segment are as follows:Year Ended December 31, 2018 2017 % Change($ in thousands) Gross written premiums$656,538 $530,120 23.8%Net written premiums$571,098 $469,891 21.5%Net earned premiums$555,684 $463,521 19.9%Losses and loss adjustment expenses(437,904) (371,717) 17.8%Underwriting expenses(74,946) (62,111) 20.7%Underwriting profit(1), (2)$42,834 $29,693 44.3%Ratios: Loss ratio78.8% 80.2% Expense ratio13.5% 13.4% Combined ratio92.3% 93.6% (1)Underwriting Profit is a non-GAAP Measure.

The loss ratio of 80.2% for the year ended December 31, 2017 includes $20.0 million, or 4.3 percentage points, of netadverse development in our loss estimates for prior accident years. The adverse reserve development in this segment in 2017 and 2018 was almost entirelyfrom one large commercial auto account in the 2016 accident year. The loss ratio for the year ended December 31, 2017 also includes $5.2 million of lossesfrom Hurricanes Harvey, Irma, and Maria primarily related to property losses in Florida. The catastrophe losses represent 1.1 percentage points of loss ratioadditions for the year.The expense ratio for this segment was slightly higher at 13.5% for 2018 compared to 13.4% in 2017. Gross fee income contributed to a reduction in theexpense ratio of 2.5 and 3.7 percentage points for the years ended December 31, 2018 and 2017, respectively.Our commercial auto business has a lower expense ratio and higher loss ratio than our other business in the segment. Commercial auto made up 56.7% ofthe segment’s net earned premiums for 2018 compared to 53.3% for 2017.As a result of the items discussed above, the underwriting profit of the Excess and Surplus Lines segment increased 44.3%, from $29.7 million for theyear ended December 31, 2017 to $42.8 million for the year ended December 31, 2018.80TABLE OF CONTENTSSpecialty Admitted Insurance SegmentResults for the Specialty Admitted Insurance segment are as follows:Year Ended December 31, 2018 2017 % Change($ in thousands) Gross written premiums$374,346 $316,430 18.3 %Net written premiums$55,840 $60,957 (8.4)%Net earned premiums$55,146 $68,110 (19.0)%Losses and loss adjustment expenses(32,623) (44,863) (27.3)%Underwriting expenses(15,551) (20,081) (22.6)%Underwriting profit(1), (2)$6,972 $3,166 120.2 %Ratios: Loss ratio59.2% 65.9% Expense ratio28.2% 29.5% Combined ratio87.4% 95.4% (1)Underwriting Profit is a non-GAAP Measure.

The favorable development in both 2018 and 2017 reflects the fact that actual loss emergence of the workers’ compensation book forprior accident years has been better than expected.The expense ratio of the Specialty Admitted Insurance segment was 28.2% for the year ended December 31, 2018 compared to the prior year ratio of29.5%. The expense ratio declined in 2018 for this segment due to gross fee income from the fronting business which increased 31.0% for the year endedDecember 31, 2018 compared to the prior year and to ceding commissions received on the 50% third-party quota share reinsurance coverage purchased onindividual risk workers' compensation business effective October 1, 2017.As a result of the items discussed above, the underwriting profit of the Specialty Admitted Insurance segment increased 120.2%, from $3.2 million forthe year ended December 31, 2017 to $7.0 million for the year ended December 31, 2018.81TABLE OF CONTENTSCasualty Reinsurance SegmentResults for the Casualty Reinsurance segment are as follows:Year Ended December 31, 2018 2017 % Change($ in thousands) Gross written premiums$135,889 $235,355 (42.3)%Net written premiums$135,734 $235,778 (42.4)%Net earned premiums$204,568 $209,478 (2.3)%Losses and loss adjustment expenses(129,749) (138,797) (6.5)%Underwriting expenses(69,716) (72,446) (3.8)%Underwriting profit (loss)(1)$5,103 $(1,765) —Ratios: Loss ratio63.4% 66.3% Expense ratio34.1% 34.5% Combined ratio97.5% 100.8% (1)Underwriting loss is a non-GAAP Measure.

The 2018 adverse reserve development was primarily related to losses from risk profiles and treaty structures that we nolonger underwrite. The loss ratio of 66.3% for the year ended December 31, 2017 includes $4.2 million, or 2.0 percentage points, of net adverse developmentin our loss estimates for prior accident years. The 2017 adverse reserve development was primarily from two contracts from 2010 through 2013 that hadhigher than expected reported losses in 2017.The expense ratio of the Casualty Reinsurance segment was 34.1% for the year ended December 31, 2018 compared to the prior year ratio of 34.5% . Theexpense ratio for the year ended December 31, 2017 was impacted by the correction of a contingent commission accrual and related commission expense,which increased underwriting expenses by $2.0 million in the year ended December 31, 2017.As a result of the items discussed above, the Casualty Reinsurance segment had an underwriting profit of $5.1 million for the year ended December 31,2018 compared to an underwriting loss of $1.8 million for the year ended December 31, 2017.Other Operating ExpensesIn addition to the underwriting, acquisition and insurance expenses of the Excess and Surplus Lines segment, the Specialty Admitted Insurance segmentand the Casualty Reinsurance segment discussed previously, other operating expenses for the Company also includes the expenses of the Corporate andOther segment.Corporate and Other SegmentOther operating expenses for the Corporate and Other segment include personnel costs associated with the Bermuda and U.S. holding companies,professional fees, and various other corporate expenses that are included in our calculation of our expense ratio and our combined ratio. Other operatingexpenses of the Corporate and Other segment represent the expenses of both the Bermuda and U.S. holding companies that were not reimbursed by oursubsidiaries, including costs associated with our internal quota share, rating agencies and strategic initiatives. These costs vary from period-to-period basedon the status of these initiatives.For the years ended December 31, 2018 and 2017, the total operating expenses of the Corporate and Other segment were $26.9 million and $25.3million, representing a 6.2% increase over the prior year. The increases were driven by compensation costs, including stock compensation expenses,associated with increases in headcount and costs associated with the formation and operations of Carolina Re, a new Class 3A reinsurer that has made anirrevocable election to be taxed as a U.S. domestic82TABLE OF CONTENTScorporation under Section 953(d) of the Code effective January 1, 2018.

The decrease in private investments was offset by increased income from our growing fixed income portfolio of bonds and bank loanparticipations which benefited from rising investment yields in 2018.Major categories of the Company’s net investment income are summarized as follows:Year Ended December 31,2018 2017(in thousands)Fixed maturity securities$34,129 $26,833Bank loan participations18,279 17,388Equity securities5,240 5,045Other invested assets5,165 14,079Cash, cash equivalents, and short-term investments2,681 1,708Trading losses(4) (4)Gross investment income65,490 65,049Investment expense(4,234) (3,930)Net investment income$61,256 $61,119The following table summarizes our investment returns:Year Ended December 31,2018 2017Annualized gross investment yield on: Average cash and invested assets3.8% 4.3%Average fixed maturity securities3.7% 3.6%Of our total cash and invested assets of $1,850.3 million at December 31, 2018, $172.5 million represents the cash and cash equivalents portion of theportfolio. The majority of the portfolio, or $1,184.2 million, is comprised of fixed maturity securities that are classified as available-for-sale and carried at fairvalue with unrealized gains and losses on these securities reported, net of applicable taxes, as a separate component of accumulated comprehensive income orloss. Also included in our investments are $261.0 million of bank loan participations, $78.4 million of equity securities, $82.0 million of short-terminvestments, and $72.3 million of other invested assets.The $261.0 million of bank loan participations in our investment portfolio are classified as held-for-investment and reported at amortized cost, net ofany allowance for credit losses. Changes in this credit allowance are included in realized gains or losses. At December 31, 2018, there was no allowance forcredit losses, as none of the loans in the Company's portfolio were considered impaired. These bank loan participations are primarily senior, secured floating-rate debt rated “BB”, “B”, or “CCC” by Standard & Poor’s or an equivalent rating from another nationally recognized statistical rating organization,83TABLE OF CONTENTSand are therefore below investment grade. Bank loans include assignments of and participations in, performing and non-performing senior corporate debtgenerally acquired through primary bank syndications and in secondary markets. They consist of, but are not limited to, term loans, the funded and unfundedportions of revolving credit loans, and similar loans and investments. At December 31, 2018 and 2017, the fair value of these securities was $250.7 millionand $236.5 million, respectively.The Company invests selectively in private debt and equity opportunities. These investments comprise the Company’s other invested assets and areprimarily focused in renewable energy, limited partnerships, and bank holding companies. Equity interests in various renewable energy LLCs generatedinvestment income of $3.0 million and $10.6 million for the years ended December 31, 2018 and 2017, respectively. The LLCs are managed by an entity forwhich two of our directors serve as officers, and the Company’s Non-Executive Chairman has invested in certain of these LLCs. These investments had acarrying value of $29.8 million at December 31, 2018. Investments in loans for renewable energy projects had investment income $1.3 million and $526,000for the years ended December 31, 2018 and 2017, respectively. Two of our directors are officers of the entities that issued the loans. The Company hasinvested in several limited partnerships that invest in concentrated portfolios of publicly-traded small cap equities, loans of middle market private equitysponsored companies, and equity tranches of collateralized loan obligations (CLOs). Income from these partnerships was $566,000 in 2018 compared to $2.6million in 2017. Together, these limited partnerships had a carrying value of $29.3 million at December 31, 2018. Income from the Company’s investmentsin renewable energy LLCs and limited partnerships is recognized under the equity method of accounting. The Company also holds $4.5 million ofsubordinated notes issued by a bank holding company. Interest income from the notes was $343,000 in both years ended December 31, 2018 and 2017. TheCompany’s Non-Executive Chairman was previously the Lead Independent Director of the bank holding company and an investor in the bank holdingcompany.For the year ended December 31, 2018, the Company recognized net realized and unrealized investment losses of $5.5 million, including $6.0 million oflosses for the change in the fair value of equity securities, $554,000 of net realized investment losses on the sale of fixed maturity securities, $2.0 million ofnet realized investment gains on the sale of bank loan securities (including an $807,000 realized gain on the repayment of the loan to the producer andsupplier of power in Puerto Rico described below), and $858,000 of net realized investment losses from an increase in our bank loan credit allowance.For the year ended December 31, 2017, the Company recognized net realized investment losses of $2.0 million. This net loss was made up of an increasein our bank loan credit allowance and an other than temporary impairment on an equity security, offset by net realized gains of $1.3 million from bank loansecurities, $368,000 from equity securities, and $328,000 from fixed maturity securities.In conjunction with its outside investment managers, the Company performs quarterly reviews of all securities within its investment portfolio todetermine whether any impairment has occurred.At December 31, 2017, management concluded that one equity security, based on the severity and duration of the impairment, had experienced an other-than-temporary impairment. Accordingly, the Company recorded an impairment loss of $1.5 million in 2017. Management concluded that none of the otherequity securities with an unrealized loss at December 31, 2017 experienced an other-than-temporary impairment. Management evaluated the near-termprospects of these other equity securities in relation to the severity and duration of the impairment, and management had the ability and intent to hold thesesecurities until a recovery of their fair value.At December 31, 2017, the Company held a participation in a loan issued by a company that produces and supplies power to Puerto Rico through apower purchase agreement with Puerto Rico Electric Power Authority (“PREPA”), a public corporation and governmental agency of the Commonwealth ofPuerto Rico. Management concluded that the loan was impaired at December 31, 2017 and established an allowance for credit losses on the loan of $759,000to reduce the loan's carrying value to zero at December 31, 2017. The unpaid principal on the loan was $807,000 at December 31, 2017.

See “—Liquidity and CapitalResources—Sources and Uses of Funds” for information regarding our senior debt facilities and trust preferred securities.Amortization of IntangiblesThe Company recorded $597,000 of amortization of intangibles for each of the years ended December 31, 2018 and 2017, respectively.Goodwill and ImpairmentWe test goodwill and other intangible assets in each operating segment for impairment at least annually. The fair value of the reporting units isdetermined by weighting the results of a discounted cash flow analysis and a valuation derived from a market-based approach. Intangible assets are valuedusing various methodologies. The projection of future cash flows is dependent upon assumptions on the future levels of income as well as business trends,prospects and market and economic conditions.We perform this assessment to determine whether there has been any impairment in the value of goodwill or intangible assets by comparing its fair valueto the net carrying value of the reporting units. If the carrying value exceeds its estimated fair value, an impairment loss is recognized and the asset is writtendown accordingly.The Company completed its impairment tests and fair value analysis for goodwill and other intangible assets during the fourth quarter of 2018 and 2017.Falls Lake General was merged into Falls Lake National in the fourth quarter of 2018. In86TABLE OF CONTENTSconnection with this merger, Falls Lake General surrendered its licenses to the various state insurance departments and reduced the carrying value of itsintangible asset for "State Licenses" to $0. This caused a $200,000 impairment in 2018. No impairment was present for the year ended December 31, 2017.Income Tax ExpenseOur effective tax rate fluctuates from period to period based on the relative mix of income reported by country and the respective tax rates imposed byeach tax jurisdiction. In 2017, the Company experienced a higher proportion of U.S.-sourced income, resulting in a higher effective tax rate for that year. ForU.S.-sourced income, our U.S. federal income tax expense differs from the amounts computed by applying the federal statutory income tax rate (21% in 2018and 35% in 2017) to income before taxes due primarily to interest income on tax-advantaged state and municipal securities, dividends received income, andexcess tax benefits on share based compensation. For the years ended December 31, 2018 and 2017, our effective tax rate was 9.9% and 21.0%, respectively.Income taxes for 2017 included $1.1 million of U.S. withholding taxes on an intercompany dividend paid from the U.S. holding company to our U.K.intermediate holding company. Income taxes for 2017 also include a $3.5 million tax benefit as the U.S. net deferred tax liability was remeasured at 21%,down from 35% in prior periods, due to the enactment of the Tax Act.87TABLE OF CONTENTSYear Ended December 31, 2017 Compared to Year Ended December 31, 2016The following table summarizes our results for the years ended December 31, 2017 and 2016:Year Ended December 31, 2017 2016 % Change($ in thousands) Gross written premiums$1,081,905 $737,398 46.7 %Net retention(1)70.9% 75.6% Net written premiums$766,626 $557,708 37.5 %Net earned premiums$741,109 $515,663 43.7 %Losses and loss adjustment expenses(555,377) (325,421) 70.7 %Other operating expenses(179,968) (160,762) 11.9 %Underwriting profit(2), (3)5,764 29,480 (80.4)%Net investment income61,119 52,638 16.1 %Net realized investment (losses) gains(1,989) 7,565 —Other income361 295 22.4 %Other expenses(539) (1,590) (66.1)%Interest expense(8,974) (8,448) 6.2 %Amortization of intangible assets(597) (597) —Income before taxes55,145 79,343 (30.5)%Income tax expense(11,579) (4,872) 137.7 %Net income$43,566 $74,471 (41.5)%Adjusted net operating income$47,385 $71,318 (33.6)%Ratios: Loss ratio74.9% 63.1% Expense ratio24.3% 31.2% Combined ratio99.2% 94.3% (1)Net retention is defined as the ratio of net written premiums to gross written premiums.​(2)See “—Reconciliation of Non-GAAP Measures” for further detail.​(3)Underwriting profit includes fee income of $28.3 million and $14.2 million for the years ended December 31, 2017 and 2016, respectively.​We had an underwriting profit of $5.8 million for the year ended December 31, 2017.

The majority of the portfolio, or $1,098.6 million, is comprised of fixed maturity and equity securities that are classified as available-for-sale andcarried at fair value with unrealized gains and losses on these securities reported, net of applicable taxes, as a separate component of accumulatedcomprehensive income or loss. Also included in our investments are $238.2 million of bank loan participations, $70.2 million of other invested assets, $36.8million of short-term investments, and $3.8 million of fixed maturity securities classified as trading and held at the U.S. holding company.

Equity interests in various renewable energy LLCs managed byaffiliates of D. E. Shaw, generated investment income of $10.6 million and $3.5 million for the years ended December 31, 2017 and 2016, respectively. Theseinvestments had a carrying value of $32.1 million at December 31, 2017. Investments in loans for renewable energy projects, primarily with affiliates of D.

This net loss was made up of an increasein our bank loan credit allowance and an other than temporary impairment on an equity security, offset by net realized gains of $1.3 million from bank loansecurities, $368,000 from equity securities, and $328,000 from fixed maturity securities.Management concluded that based on the severity and duration of the impairment associated with an equity security, the security had experienced another-than-temporary impairment. Accordingly, the Company recorded an impairment loss of $1.5 million in 2017. Management concluded that none of theother equity securities with an unrealized loss at December 31, 2017 and 2016 experienced an other-than-temporary impairment. Management has evaluatedthe near-term prospects of these other equity securities in relation to the severity and duration of the impairment, and management has the ability and intentto hold these securities until a recovery of their fair value.At December 31, 2015, the Company held participations in two loans issued by companies that produce and supply power to Puerto Rico through powerpurchase agreements with PREPA, a public corporation and governmental agency of the Commonwealth of Puerto Rico. PREPA’s credit strength and abilityto make timely payments was impacted by the economic conditions in Puerto Rico, thus raising doubt about the companies’ ability to meet the debtobligations held by the Company. In June 2016, one of the loans was repaid in full at its scheduled maturity. Management concluded that the remaining loanwas impaired at December 31, 2016. The loan had a carrying value of $1.7 million, unpaid principal of $2.0 million, and an allowance for credit losses of$177,000 at December 31, 2016. In July 2017, PREPA filed a petition for relief in U.S. District Court under Title III of the Puerto Rico Oversight,Management, and Economic Stability Act. Also in 2017, the devastation caused by Hurricane Maria on the island of Puerto Rico raised additional doubtabout PREPA's ability to make payments to the issuer. The maturity of the remaining loan, originally scheduled for November 2017, was deferred until March2018. Management established an allowance for credit losses of $759,000 to reduce the loan's carrying value to zero at both September 30, 2017 andDecember 31, 2017. The unpaid principal on the loan was $807,000 at December 31, 2017.The Company’s bank loan portfolio includes loans to oil and gas companies in the energy sector.

Management concluded that three of these loans were impaired as of December 31, 2017, and accordingly,an allowance for credit losses of $2.3 million was established on the loans. After recording this impairment, the loans had a carrying value of $4.6 million atDecember 31, 2017 and unpaid principal of $6.9 million. All of the other loans are current at December 31, 2017. At December 31, 2016, one loan wasimpaired with a carrying value of $1.6 million, unpaid principal of $2.2 million and an allowance for credit losses of $545,000.Management also concluded that one non-energy sector loan was impaired at December 31, 2017.

In 2017, particularly, the Company experienced a higher proportion of U.S.-sourced income, increasing the effective tax rate for theyear. For U.S.-sourced income, our U.S. federal income tax expense differs from the amounts computed by applying the federal statutory income tax rate toincome before taxes due primarily to interest income on tax-advantaged state and municipal securities (state and municipal securities represented 13.1% and10.4% of our available-for-sale securities at December 31, 2017 and 2016, respectively), dividends received income, and excess tax benefits on share basedcompensation. For the years ended December 31, 2017 and 2016, our effective tax rate was 21.0% and 6.1%, respectively. Income taxes for 2017 included$1.1 million of U.S. withholding taxes on an intercompany dividend paid from the U.S. holding company to our U.K. intermediate holding company. Incometaxes for 2017 also include a $3.5 million tax benefit as the U.S. net deferred tax liability was remeasured at 21%, down from 35% in prior periods, due to theenactment of the Tax Act.Financial results for 2017 reflect provisional amounts related to the December 2017 enactment of the Tax Act. These provisional estimates are based onthe Company’s initial analysis and current interpretation of the legislation. Given the complexity of the Tax Act, anticipated guidance from the U.S.Department of the Treasury, and the potential for additional guidance from the Securities and Exchange Commission (SEC) or the Financial AccountingStandards Board, these estimates may be adjusted during 2018.Liquidity and Capital ResourcesSources of FundsDividendsWe are organized as a Bermuda holding company with our operations conducted by our wholly-owned subsidiaries. Accordingly, our holding companymay receive cash through loans from banks, issuance of equity and debt securities, corporate service fees or dividends received from our subsidiaries and/orother transactions. Our U.S. holding company may receive cash in a similar manner and also through payments from our subsidiaries pursuant to our U.S.consolidated tax allocation agreement.The payment of dividends by our subsidiaries to us is limited by statute. In general, the laws and regulations applicable to our domestic insurancesubsidiaries limit the aggregate amount of dividends or other distributions that they may declare or pay within any 12-month period without advanceregulatory approval. Generally, the limitations are based on the greater of statutory net income for the preceding year or 10.0% of statutory surplus at the endof the preceding year. In addition, insurance regulators have broad powers to prevent reduction of statutory surplus to inadequate levels and could refuse topermit the payment of dividends calculated under any applicable formula. See Item 1— “U.S. Insurance Regulation—State Regulation” for additionalinformation. The Bermuda Insurance Act of 1978 prohibits an insurer from declaring or paying a dividend if it is in breach of its minimum solvency margin,its enhanced capital requirement, or its minimum liquidity ratio, or if the declaration or payment of such dividend would cause such a breach. An insurer candeclare or pay dividends without prior regulatory approval up to 25% of the total statutory capital and surplus. At December 31, 2018, the maximumcombined amount of dividends that can be paid without prior regulatory approval was approximately $109.8 million. However, this dividend amount issubject to annual enhanced solvency requirement calculations. Additionally, the maximum amount of dividends available to the U.S. holding company fromour U.S. insurance subsidiaries during 2019 without regulatory approval is $24.2 million.At December 31, 2018, our Bermuda holding company had $240,000 of cash and cash equivalent assets. At December 31, 2018, our U.S. holdingcompany had $53.7 million of cash and invested assets, comprised of cash and cash equivalents of $7.3 million, other invested assets of $46.1 million, andshort-term investments of $325,000, which are not subject to regulatory restrictions. Additionally, our U.K. intermediate holding company had no investedassets and cash of less than $10,000 at December 31, 2018.Our net written premiums to surplus ratio (defined as net written premiums to regulatory capital and surplus) is reviewed by management as well as ourrating agency as a component of leverage and efficiency of deployed capital. Our net written premiums to surplus ratio was 1.1x, 1.2x, and 0.9x for the yearsended December 31, 2018, 2017, and 2016, respectively.Credit AgreementsThe Company has a $215.0 million senior revolving credit facility (as amended or amended and restated, the “2013 Facility”). The 2013 Facility iscomprised of the following at December 31, 2018:99TABLE OF CONTENTS•A $102.5 million secured revolving facility utilized by JRG Re to issue letters of credit for the benefit of third-party reinsureds. This portion of ourcredit facility is secured by our investment securities. At December 31, 2018, the Company had $75.5 million of letters of credit issued under thesecured facility.​•A $112.5 million unsecured revolving facility to meet the working capital needs of the Company. All unpaid principal on the revolver is due atmaturity. Interest accrues quarterly and is payable in arrears at 3-month LIBOR plus a margin which is currently 1.5% and is subject to changeaccording to terms in the credit agreement. At December 31, 2018 and 2017, the Company had a drawn balance of $73.3 million outstanding on theunsecured revolver.​The 2013 Facility has been amended from time to time since its inception in 2013. On December 7, 2016, the Company entered into an Amended andRestated Credit Agreement for the 2013 Facility which, among other things, extended the maturity date of the Facility until December 7, 2021 and modifiedother terms including reducing the rate of interest and reducing the number of financial covenants. On June 8, 2017, the Company entered into a FirstAmendment to the amended and restated 2013 Facility, which among other things, modified the financial covenants and increased the amount of additionaldebt the Company may incur under new financings, subject to compliance with certain conditions.The 2013 Facility contains certain financial and other covenants (including risk-based capital, minimum shareholders’ equity levels, maximum ratios oftotal debt outstanding to total capitalization and minimum fixed charge coverage ratios) with which the Company was in compliance at December 31, 2018.On August 2, 2017, the Company, and its wholly-owned subsidiary, JRG Re, together as borrowers, entered into a credit agreement (the "2017 Facility")that provides the Company with a revolving line of credit of up to $100 million, which may be used for loans and letters of credit made or issued, at theborrowers' option, on a secured or unsecured basis. Obligations under the 2017 Facility carry a variable rate of interest subject to terms in the credit agreementand will mature 30 days after notice of termination from the lender. The 2017 Facility contains certain financial and other covenants which we are incompliance with at December 31, 2018. The loans and letters of credit made or issued under the revolving line of credit of the 2017 Facility may be used tofinance the borrowers' general corporate purposes. At December 31, 2018, unsecured loans of $30.0 million and secured letters of credit totaling $7.6 millionwere outstanding on the 2017 Facility.In May 2004, we issued $15.0 million of senior debt due April 29, 2034. The senior debt is not redeemable by the holder or subject to sinking fundrequirements. Interest accrues quarterly and is payable in arrears at a floating rate per annum equal to the 3-month LIBOR plus 3.85%. This senior debt isredeemable at par prior to its stated maturity at our option in whole or in part. The terms of the senior debt contain certain covenants, with which we are incompliance at December 31, 2018, and which, among other things, restrict our ability to assume senior indebtedness secured by our U.S. holding company'scommon stock or its subsidiaries' capital stock or to issue shares of its subsidiaries' capital stock.Interest payable is included in “accrued expenses” in the accompanying consolidated balance sheets.The following table summarizes the nature and terms of the junior subordinated debt and trust preferred securities outstanding at December 31, 2018(including the Company’s repurchase of a portion of these trust preferred securities):James RiverCapitalTrust I James RiverCapitalTrust II James RiverCapitalTrust III James RiverCapitalTrust IV FranklinHoldings II(Bermuda)CapitalTrust I($ in thousands)Issue dateMay 26, 2004 December 15, 2004 June 15, 2006 December 11, 2007 January 10, 2008Principal amount of trust preferred securities$7,000 $15,000 $20,000 $54,000 $30,000Principal amount of junior subordinated debt$7,217 $15,464 $20,619 $55,670 $30,928Carrying amount of junior subordinated debtnet of repurchases$7,217 $15,464 $20,619 $44,827 $15,928Maturity date of junior subordinated debt,unless accelerated earlierMay 24, 2034 December 15, 2034 June 15, 2036 December 15, 2037 March 15, 2038Trust common stock$217 $464 $619 $1,670 $928Interest rate, per annumThree-MonthLIBOR plus4.0% Three-MonthLIBOR plus3.4% Three-MonthLIBOR plus3.0% Three-MonthLIBOR plus3.1% Three-MonthLIBOR plus4.0%All of the junior subordinated debt is currently redeemable at 100.0% of the unpaid principal amount at our option.The junior subordinated debt contains certain covenants with which we are in compliance as of December 31, 2018.100TABLE OF CONTENTSAt December 31, 2018 and December 31, 2017, the ratio of total debt outstanding, including both senior debt and junior subordinated debt, to totalcapitalization (defined as total debt plus total shareholders’ equity) was 23.9% and 22.6%, respectively. Having debt as part of our capital structure allows usto generate a higher return on equity and greater book value per share results than we could by using equity capital alone.Ceded ReinsuranceOur insurance segments enter into reinsurance contracts to limit our exposure to potential losses arising from large risks, to protect against theaggregation of several risks in a common loss occurrence, and to provide additional capacity for growth. Our reinsurance is contracted under excess of lossand quota share reinsurance contracts. In excess of loss reinsurance, the reinsurer agrees to assume all or a portion of the ceding company’s losses in excess ofa specified amount. The premiums payable to the reinsurer are negotiated by the parties based on their assessment of the amount of risk being ceded to thereinsurer because the reinsurer does not share proportionately in the ceding company’s losses. In quota share reinsurance, the reinsurer agrees to assume aspecified percentage of the ceding company’s losses arising out of a defined class of business in exchange for a corresponding percentage of premiums. Forthe years ended December 31, 2018, 2017, and 2016 our net premium retention was 65.4%, 70.9% and 75.6%, respectively.The following is a summary of our Excess and Surplus Lines segment’s ceded reinsurance in place as of December 31, 2018:Line of BusinessCompany RetentionCasualty Primary Specialty Casualty, includingProfessional LiabilityUp to $1.0 million per occurrence, subject to a $1.0 million aggregate deductible.Primary CasualtyUp to $2.0 million per occurrence.(1)Excess CasualtyUp to $1.0 million per occurrence.(2)PropertyUp to $5.0 million per event.(3)(1)Total exposure to any one claim is generally $1.0 million.​(2)For policies with an occurrence limit up to $10.0 million, the excess casualty treaty is set such that our retention is no more than $1.0 million.(3)The property catastrophe reinsurance treaty has a limit of $40.0 million with one reinstatement.​In our Excess and Surplus Lines segment, we write a small book of excess property insurance, but we do not write primary property insurance. In ourExcess and Surplus Lines segment, we have a surplus share reinsurance treaty in effect that was specifically designed to cover property risks. The surplusshare treaty along with facultative reinsurance helps ensure that our net retained limit per risk will be $5.0 million or less.We use catastrophe modeling software to analyze the risk of severe losses from hurricanes and earthquakes on our exposure. We utilize the model in ourrisk selection, pricing, and to manage our overall PML accumulations. A PML is an estimate of the amount we would expect to pay in any one catastropheevent within a given annual probability of occurrence (i.e. a return period or loss exceedance probability). Based upon the modeling of our Excess andSurplus Lines segment, a $45.0 million gross catastrophe loss would exceed our 1 in 1,000 year PML. In the event of a $45.0 million gross propertycatastrophe loss to the Excess and Surplus Lines segment, we estimate our pre-tax cost at approximately $7.1 million, including reinstatement premiums andnet retentions. In addition to this retention, we would retain any losses in excess of our reinsurance coverage limits.Our Specialty Admitted Insurance segment purchases reinsurance for at least 50% of the exposed limits on specialty admitted property-casualtybusiness. The segment enters into reinsurance contracts for the individual risk workers’ compensation business as well as fronting and program business.While the segment focuses on casualty business, incidental property risk is incurred in the fronting and program business. The segment is covered for $44.0million in excess of $1.0 million per occurrence to manage its property exposure to an approximate 1 in 1,000 year PML.101TABLE OF CONTENTSThe following is a summary of our Specialty Admitted Insurance segment’s ceded reinsurance in place as of December 31, 2018:Line of BusinessCoverageCasualty Workers’ CompensationQuota share coverage for 50% of the first $600,000.(1)(2) Excess of loss coverage for $29.4 million in excess of $600,000.(1)(2)Auto ProgramsQuota share coverage for 90% of limits up to $1.5 million liability and $5.0 million physicaldamage per occurrenceGeneral Liability & Professional Liability –ProgramsQuota share coverage for 90% - 100% of limits up to $2.0 million per occurrence.Property Commercial Property within Package - Programs Quota share coverage for 100% of limits up to $25.0 million per occurrence.Catastrophe Coverage Excess of Loss coverage for $44.0 million in excess of $1.0 million(1)Excluding one program which has quota share coverage for 90% of the first $1.0 million per occurrence and excess of loss coverage for $49.0 millionin excess of $1.0 million.​(2)Includes any residual market pools.In our Casualty Reinsurance segment, we also have limited property catastrophe exposure. In the aggregate, we believe our pre-tax group-wide PMLfrom a 1 in 1,000 year property catastrophe event would not exceed $10.0 million, inclusive of reinstatement premiums payable.We also have a clash and contingency reinsurance treaty to cover both the Excess and Surplus Lines and Specialty Admitted Insurance segments in theevent of a claims incident involving more than one of our insureds. The treaty covers $10.0 million in excess of a $2.0 million retention for loss occurrenceswithin the treaty term. This coverage has two reinstatements in the event we exhaust any of the coverage. As of December 31, 2018, our average net retainedlimit per risk is $2.5 million.The Company’s insurance segments remain liable to policyholders if its reinsurers are unable to meet their contractual obligations under applicablereinsurance agreements. We establish allowances for amounts considered uncollectible. At December 31, 2018, there was no allowance for such uncollectiblereinsurance recoverables. To minimize exposure to significant losses from reinsurance insolvencies, the Company evaluates the financial condition of itsreinsurers and monitors concentrations of credit risk. The Company generally seeks to purchase reinsurance from reinsurers with A.M. Best financial strengthratings of “A-” (Excellent) or better. The Company’s reinsurance contracts generally require reinsurers that are not authorized as reinsurers under U.S. stateinsurance regulations or that experience rating downgrades from rating agencies below specified levels to fund their share of the Company’s cededoutstanding losses and loss adjustment expense reserves, typically through the use of irrevocable and unconditional letters of credit. In frontingarrangements, which the Company conducts through its Specialty Admitted Insurance segment, we are subject to credit risk with regard to insurancecompanies who act as reinsurers for us in such arrangements. We customarily require a collateral trust arrangement to secure the obligations of the insuranceentity for whom we are fronting.At December 31, 2018, we had reinsurance recoverables on unpaid losses of $467.4 million and reinsurance recoverables on paid losses of $18.3 million,and all material recoverable amounts were from companies with A.M. Best ratings of “A-” or better or collateral had been posted by the reinsurer for ourbenefit.102TABLE OF CONTENTSThe following table sets forth our most significant reinsurers by amount of reinsurance recoverables and the amount of reinsurance recoverablespertaining to each such reinsurer as well as its A.M.

All material reinsurance recoverable amounts from these reinsurers are collateralized.Amounts Recoverable from an Indemnifying PartyThe Company is a party to a set of insurance contracts with an insured group of companies under which the Company pays losses and loss adjustmentexpenses on the contract. The Company has indemnity agreements with this group of insured parties (non-insurance entities) and is contractually entitled toreceive reimbursement for a significant portion of the losses and loss adjustment expenses paid on behalf of the insured parties and other expenses incurredby the Company. The insured parties are required to collateralize all amounts currently due to the Company and to provide additional collateral sufficient tocover the amounts that may be recoverable under the indemnity agreements, including among other things case loss and loss adjustment expense reserves,IBNR loss and loss adjustment expense reserves, extra contractual obligations and excess of policy limits liabilities. This collateral is currently providedthrough a collateral trust arrangement established in favor of the Company by a captive insurance company affiliate of the insured group. At December 31,2018, the cash equivalent collateral held in the collateral trust arrangement was approximately $1,099.2 million, which exceeds the amount of claimsreceivable and unpaid reported losses and loss adjustment expenses outstanding. The Company has ongoing exposure to estimated losses and expenses onthese contracts growing at a faster pace than growth in our collateral balances. In addition, we have credit exposure if our estimates of future losses and lossadjustment expenses and other amounts recoverable, which are the basis for establishing collateral balances, are lower than actual amounts paid or payable.The amount of our credit exposure in any of these instances could be material. To mitigate these risks, we closely and frequently monitor our exposurecompared to our collateral held, and we request additional collateral when our analysis indicates that we have uncollateralized exposure.Cash FlowsOur sources of operating funds consist primarily of premiums written, investment income, reinsurance recoveries and proceeds from offerings of debt andequity securities and from sales and redemptions of investments. We use the operating cash flows primarily to pay operating expenses, losses and lossadjustment expenses, and income taxes. Cash flow from operations may differ substantially from net income. The potential for a large claim under aninsurance or reinsurance contract means that substantial and unpredictable payments may need to be made within relatively short periods of time. We havegenerated positive cash flow from operations in each of the three years ended December 31, 2018, 2017, and 2016. The following table summarizes our cashflows:103TABLE OF CONTENTSYear Ended December 31,2018 2017 2016(in thousands)Cash and cash equivalents provided by (used in): Operating activities$290,028 $207,816 $154,349Investing activities(266,772) (104,741) (80,764)Financing activities(14,294) (49,364) (70,207)Change in cash and cash equivalents$8,962 $53,711 $3,378Cash provided by operating activities reflects our growth and the fact that we are collecting premiums receivable at a quicker rate than we are paying lossand loss adjustment expenses. The growth in reserves for losses and loss adjustment expenses exceeded the growth in premiums receivable and reinsurancebalances by $226.6 million in 2018, $147.7 million in 2017, and $1.4 million in 2016.Cash used in investing activities reflects our efforts to enhance the yield in our investment portfolio by investing available cash and cash equivalentsinto higher yielding fixed maturity securities and bank loan participations. Cash and cash equivalents comprised 9.3%, 10.1% and 7.6% of total cash andinvested assets at December 31, 2018, 2017 and 2016, respectively.Cash used in financing activities is primarily due to dividends to shareholders of $36.1 million in 2018, $50.8 million in 2017, and $66.0 million in2016. In addition, we drew down $20.0 million and $10.0 million on our 2017 Facility in 2018 and 2017, respectively.RatingsThe A.M. Best financial strength rating for our group’s regulated insurance subsidiaries is “A” (Excellent). This rating reflects A.M. Best’s opinion of ourinsurance subsidiaries’ financial strength, operating performance and ability to meet obligations to policyholders and is not an evaluation directed towardsthe protection of investors. The rating for our operating insurance and reinsurance companies of “A” (Excellent) is the third highest rating of the thirteenratings issued by A.M. Best and is assigned to insurers that have, in A.M. Best’s opinion, an excellent ability to meet their ongoing obligations topolicyholders.The financial strength ratings assigned by A.M. Best have an impact on the ability of our regulated subsidiaries to attract and retain agents and brokersand on the risk profiles of the submissions for insurance that our subsidiaries receive. The “A” (Excellent) ratings assigned to our insurance and reinsurancesubsidiaries are consistent with our business plans and we believe allow our subsidiaries to actively pursue relationships with the agents and brokersidentified in their marketing plans.EquityShare activity in 2017 and 2018 includes issuances from stock option exercises and RSU vesting, increasing the number of common shares outstandingfrom 29,257,566 at December 31, 2016 to 29,696,682 at December 31, 2017 and 29,988,460 at December 31, 2018.Share Based Compensation ExpenseFor the years ended December 31, 2018, 2017, and 2016, the Company recognized $6.2 million, $7.7 million and $5.5 million, respectively, of sharebased compensation expense.

As more fully discussed in“—Critical Accounting Policies—Reserves for Losses and Loss Adjustment Expenses” above, the estimation of losses is based on various complex andsubjective judgments. Actual losses paid may differ, perhaps significantly, from the reserve estimates reflected in our consolidated financial statements.Similarly, the timing of payment of our estimated losses is not fixed and there may be significant changes in actual payment activity. The assumptions usedin estimating the likely payments due by period are based on our historical claims payment experience and industry payment patterns, but due to the inherentuncertainty in the process of estimating the timing of such payments, there is a risk that the amounts paid in any such period can be significantly differentfrom the amounts disclosed above.Financing obligations represent obligations for a build-to-suit lease relating to an investment by the Company for a minority interest in a real estatelimited partnership pursuant to which we were deemed to be an owner for accounting purposes. Upon adoption of ASU 2016-02, Leases (Topic 842) onJanuary 1, 2019, the Company will derecognize the $30.9 million financing obligation associated with the lease designated as build-to-suit under theprevious guidance. The lease will be classified as an operating lease under the new standard. The Company will record a right-of-use asset and lease liabilityfor the lease under the new standard.The amounts in the above table represent our gross estimates of known liabilities as of December 31, 2018 and do not include any allowance for claimsfor future events within the time period specified. Accordingly, it is highly likely that the total amounts paid out in the time periods shown will be greaterthan those indicated in the table.Interest on debt obligations was calculated using the LIBOR rate as of December 31, 2018 with the assumption that interest rates would remain flat overthe remainder of the period that the debt was outstanding.Off-Balance Sheet ArrangementsWe do not have any off-balance sheet arrangements.Reconciliation of Non-GAAP MeasuresReconciliation of Underwriting ProfitWe believe that the disclosure of underwriting profit by individual segment and of the Company as a whole is useful to investors, analysts, ratingagencies and other users of our financial information in evaluating our performance because our objective is to consistently earn underwriting profits. Weevaluate the performance of our segments and allocate resources based primarily on underwriting profit. Our definition of underwriting profit may not becomparable to that of other companies.106TABLE OF CONTENTSThe following table reconciles the underwriting profit by individual segment and for the entire Company to consolidated income before U.S. federalincome taxes for the years ended December 31, 2018, 2017 and 2016.Year Ended December 31,2018 2017 2016(in thousands)Underwriting profit (loss) of the operating segments: Excess and Surplus Lines$42,834 $29,693 $47,235Specialty Admitted Insurance6,972 3,166 2,872Casualty Reinsurance5,103 (1,765) (194)Total underwriting profit of the operating segments54,909 31,094 49,913Other operating expenses of the Corporate and Other segment(26,903) (25,330) (20,433)Underwriting profit(1)28,006 5,764 29,480Net investment income61,256 61,119 52,638Net realized investment (losses) gains(5,479) (1,989) 7,565Other income505 361 295Other expenses(1,300) (539) (1,590)Interest expense(11,553) (8,974) (8,448)Amortization of intangible assets(597) (597) (597)Income before taxes$70,838 $55,145 $79,343(1)Underwriting profit includes gross fee income of $28.7 million, $28.3 million, and $14.2 million for the years ended December 31, 2018, 2017, and2016, respectively.​Reconciliation of Adjusted Net Operating IncomeWe define adjusted net operating income as net income excluding certain non-operating expenses such as net realized and unrealized investment gainsand losses, expenses related to due diligence costs for various merger and acquisition activities, professional service fees related to the filing of registrationstatements for the offering of securities, severance costs associated with terminated employees and interest and other expenses on a leased building that weare deemed to own for accounting purposes. We use adjusted net operating income as an internal performance measure in the management of our operationsbecause we believe it gives our management and other users of our financial information useful insight into our results of operations and our underlyingbusiness performance. Adjusted net operating income should not be viewed as a substitute for net income calculated in accordance with GAAP, and ourdefinition of adjusted net operating income may not be comparable to that of other companies.Our income before taxes and net income for the years ended December 31, 2018, 2017 and 2016 reconcile to our adjusted net operating income asfollows:Year Ended December 31,2018 2017 2016IncomeBeforeTaxes Net Income IncomeBeforeTaxes NetIncome IncomeBeforeTaxes NetIncome(in thousands)Income as reported$70,838 $63,830 $55,145 $43,566 $79,343 $74,471Net realized and unrealized losses(gains) on investments5,479 4,374 1,989 1,375 (7,565) (5,207)Other expenses1,100 941 539 575 1,590 1,136Impairment of intangible assets200 200 — — — —Dividend withholding taxes— — — 1,053 — —Interest expense on leased building theCompany is deemed to own foraccounting purposes1,584 1,251 1,256 816 1,412 918Adjusted net operating income$79,201 $70,596 $58,929 $47,385 $74,780 $71,318107TABLE OF CONTENTSTangible Equity and Tangible Equity per ShareKey financial measures that we use to assess our longer term financial performance include the percentage growth in our tangible equity per share andour return on tangible equity. We believe tangible equity is a good measure to evaluate the strength of our balance sheet and to compare returns relative tothis measure. Tangible equity before dividends increased 10.9% from $474.5 million at December 31, 2017 to $526.1 million at December 31, 2018, largelydue to net income of $63.8 million and $22.2 million of unrealized losses, net of taxes, on available-for-sale fixed maturity securities. Tangible equity afterdividends increased 3.2% from $474.5 million at December 31, 2017 to $489.9 million at December 31, 2018. Tangible equity per common share was $16.34at December 31, 2018, net of $1.20 of dividends per share paid by the Company during 2018. The 2018 adjusted net operating income return on averagetangible equity was 14.8%, which compares to 9.7% for the full year 2017.We define tangible equity as the sum of shareholders’ equity less goodwill and intangible assets (net of amortization). Our definition of tangible equitymay not be comparable to that of other companies, and it should not be viewed as a substitute for shareholders’ equity calculated in accordance with GAAP.The following table reconciles shareholders’ equity to tangible equity as of December 31, 2018, 2017 and 2016 and reconciles tangible equity to predividend tangible equity as of December 31, 2018:As of December 31,2018 20172016Equity Equityper share Equity Equityper shareEquity Equityper share(in thousands, except per share amounts)Shareholders’ equity$709,241 $23.65 $694,699 $23.39 $693,221 $23.69Less: Goodwill181,831 6.06 181,831 6.12 181,831 6.21Intangible assets37,537 1.25 38,334 1.29 38,931 1.33Tangible equity$489,873 $16.34 $474,534 $15.98 $472,459 $16.15Dividends to shareholders forthe year ended December 31,201836,246 1.20 Pre-dividend tangible equity$526,119 $17.54 108TABLE OF CONTENTSItem 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK​Market risk is the risk of economic losses due to adverse changes in the estimated fair value of a financial instrument as the result of changes in equityprices, interest rates, foreign currency exchange rates and commodity prices. Our consolidated balance sheets include assets and liabilities with estimated fairvalues that are subject to market risk. Our primary market risks have been interest rate risk associated with investments in fixed maturities and equity pricerisk associated with investments in equity securities. We do not have material exposure to foreign currency exchange rate risk or commodity risk.Interest Rate RiskOur fixed maturity and preferred stock investments and borrowings are subject to interest rate risk. Increases and decreases in interest rates typicallyresult in decreases and increases, respectively, in the fair value of these financial instruments.The majority of our investable assets come from premiums paid by policyholders. These funds are invested predominantly in high quality corporate,government and municipal bonds with relatively short durations. The investment portfolio has an average duration of approximately 3.4 years atDecember 31, 2018, and fixed maturity securities and preferred stock investments in the portfolio have an average rating by at least one nationallyrecognized rating organization of “AA-”. See Note 2 to the Notes to the Audited Consolidated Financial Statements for disclosure of contractual maturitydates of our fixed maturity portfolio. The changes in the estimated fair value of the fixed maturity portfolio classified as available-for-sale are presented as acomponent of shareholders’ equity in accumulated other comprehensive income, net of taxes.We work to manage the impact of interest rate fluctuations on our fixed maturity and preferred stock portfolio. The effective duration is managed withconsideration given to the estimated duration of our liabilities. We have investment guidelines that set targets for average duration and maturity.Our investment manager employs a model to estimate the effect of interest rate risk on the fair values of our fixed maturity and preferred stock securitiesand our bank loan participations. Our bank loan participations are primarily floating-rate debt, so their fair values are less sensitive to changes in interest ratesthan our fixed maturity and preferred stock securities. The model estimates the impact of interest rate changes on a wide range of factors, including durationand prepayment. Fair values of borrowings are estimated based on the net present value of cash flows, using a representative set of possible future interest ratescenarios. The model requires that numerous assumptions be made about the future. To the extent that any of the assumptions are invalid, incorrect estimatescould result. The usefulness of a single point-in-time model is limited, as it is unable to accurately incorporate the full complexity of market interactions.The following table summarizes our interest rate risk and shows the effect of hypothetical changes in interest rates as of December 31, 2018. The selectedhypothetical changes do not indicate what could be the potential best or worst case scenarios.As of December 31, 2018EstimatedFair Value HypotheticalChange inInterest Rates(bp=basis points) EstimatedFair Value afterHypothetical Changein Interest Rates EstimatedHypothetical PercentageIncrease (Decrease) inFair Value($ in thousands)Total fixed maturity and preferred stock investments$1,244,942 200 bp decrease $1,353,626 8.7 % 100 bp decrease 1,298,848 4.3 % 100 bp increase 1,191,907 (4.3)% 200 bp increase 1,141,612 (8.3)%Bank Loan Participations$250,697 200 bp decrease $254,508 1.5 % 100 bp decrease 251,474 0.3 % 100 bp increase 250,371 (0.1)% 200 bp increase 250,120 (0.2)%Liabilities$235,374 200 bp decrease $237,485 0.9 % 100 bp decrease 236,372 0.4 % 100 bp increase 234,476 (0.4)% 200 bp increase 233,668 (0.7)%109TABLE OF CONTENTSEquity Price RiskA portion of our portfolio is invested in equity securities, which have historically produced higher long-term returns relative to fixed maturities. We ownpreferred stocks, generally in the financial services industry, and common stocks. The changes in the estimated fair value of the equity securities portfolio arerecognized in net income.At December 31, 2018, our equity securities portfolio was concentrated in terms of the number of issuers and industries. Such concentrations can lead tohigher levels of price volatility.The following table summarizes our equity price risk and shows the effect of a hypothetical 35% increase or decrease in the fair value of our equitysecurities portfolio as of December 31, 2018. We believe that this range represents a reasonably likely scenario, as the largest annual increases and decreasesin the S&P 500 Index in the past twenty-five years were 34.1% (1995) and (38.5%) (2008), respectively.

See Index to Financial Statements and Schedules on page F-1.Item 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE​Not applicable.Item 9A.CONTROLS AND PROCEDURES​Evaluation of Disclosure Controls and ProceduresWe maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports we file or submitunder the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that suchinformation is accumulated and communicated to our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer ("CFO"), asappropriate, to allow timely decisions regarding required disclosure. In connection with the preparation of this Annual Report on Form 10-K, ourmanagement carried out an evaluation, under the supervision and with the participation of our CEO and CFO, as of December 31, 2018, of the effectivenessof the design and operation of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) and 15d-15(e) under the Exchange Act.Based upon this evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of December 31, 2018.Management’s Annual Report on Internal Control over Financial ReportingManagement is responsible for establishing and maintaining adequate internal control over financial reporting for the Company, as such term is definedin Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is a process designed to provide reasonable assuranceregarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally acceptedaccounting principles. Internal control over financial reporting includes those policies and procedures that: pertain to the maintenance of records that, inreasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; provide reasonable assurance that transactions are recorded asnecessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expendituresare being made only in accordance with authorizations of our management and directors; and provide reasonable assurance regarding prevention or timelydetection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements. Because of its inherentlimitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to futureperiods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies orprocedures may deteriorate.110TABLE OF CONTENTSManagement has conducted an assessment, including testing, of the effectiveness of our internal control over financial reporting as of December 31,2018. In making its assessment of internal control over financial reporting, management used the criteria in Internal Control — Integrated Framework (2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, the Company’s management has concludedthat, as of December 31, 2018, the Company’s internal control over financial reporting was effective.Ernst & Young LLP, the independent registered public accounting firm that audited the Consolidated Financial Statements of the Company included inthis Annual Report, has audited the effectiveness of internal control over financial reporting as of December 31, 2018.

Ourresponsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firmregistered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and theapplicable rules and regulations of the Securities and Exchange Commission and the PCAOB.We conducted our audit in accordance with the standards of the PCAOB.

We believe that our audit provides a reasonable basis for our opinion.Definition and Limitations of Internal Control Over Financial ReportingA company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financialreporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’sinternal 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 asnecessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of thecompany are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assuranceregarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on thefinancial statements.Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluationof effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree ofcompliance with the policies or procedures may deteriorate./s/ Ernst & Young LLPPittsburgh, PennsylvaniaFebruary 27, 2019F-3TABLE OF CONTENTSJAMES RIVER GROUP HOLDINGS, LTD.

(referred to as “JRG Holdings” or, with its subsidiaries, the “Company”) is an exempted holding company registeredin Bermuda, organized for the purpose of acquiring and managing insurance and reinsurance entities.The Company owns five insurance companies based in the United States (“U.S.”) focused on specialty insurance niches and two Bermuda-basedreinsurance companies as described below:•James River Group Holdings UK Limited (“James River UK”) is an insurance holding company formed in 2015 in the United Kingdom (“U.K.”). TheCompany contributed James River Group, Inc. (“James River Group”), a U.S. insurance holding company, to James River UK in 2015.​•James River Group is a Delaware domiciled insurance holding company formed in 2002, which owns all of the Company’s U.S.-based subsidiaries,either directly or indirectly through one of its wholly-owned U.S. subsidiaries. James River Group oversees the Company’s U.S. insurance operationsand maintains all of the outstanding debt in the U.S.​•James River Insurance Company (“James River Insurance”) is an Ohio domiciled excess and surplus lines insurance company that, with its wholly-owned insurance subsidiary, James River Casualty Company, is authorized to write business in every state and the District of Columbia.​•Falls Lake National Insurance Company (“Falls Lake National”) is an Ohio domiciled insurance company which wholly owns Stonewood InsuranceCompany (“Stonewood Insurance”), a North Carolina domiciled company, and Falls Lake Fire and Casualty Company, a California domiciledcompany. Falls Lake National began writing specialty admitted fronting and program business in late 2013. Falls Lake Fire and Casualty Companybegan operations in 2016.​​•JRG Reinsurance Company, Ltd. (“JRG Re”) was formed in 2007 and commenced operations in 2008. JRG Re, a Bermuda domiciled reinsurer,primarily provides non-catastrophe casualty reinsurance to U.S. third parties and to the Company’s U.S.-based insurance subsidiaries.•Carolina Re Ltd ("Carolina Re") was formed in 2018 and provides reinsurance to the Company's U.S.-based insurance subsidiaries. Carolina Re isalso the cedent on a stop loss reinsurance treaty with JRG Re.​Basis of Presentation and Principles of ConsolidationThe consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), which vary in somerespects from statutory accounting practices (“SAP”) which are prescribed or permitted by the various state insurance departments in the U.S. or by insuranceregulators in Bermuda. The accompanying consolidated financial statements include the accounts and operations of the Company and its subsidiaries.Intercompany transactions and balances have been eliminated.Estimates and AssumptionsPreparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect theamounts reported in the consolidated financial statements and accompanying disclosures. Those estimates are inherently subject to change, and actual resultsmay ultimately differ from those estimates.Fixed Maturity and Equity SecuritiesFixed maturity securities classified as “available-for-sale” are carried at fair value, and unrealized gains and losses on such securities, net of any deferredtaxes, are reported as a separate component of accumulated other comprehensive income. Fixed maturity securities purchased for short-term resale areclassified as “trading” and are carried at fair value with unrealized gains and losses included in earnings as a component of net investment income. TheCompany does not have any securities classified as “held-to-maturity”.Fair value generally represents quoted market value prices for securities traded in the public marketplace or prices analytically determined using bid orclosing prices for securities not traded in the public marketplace.F-9TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016Premiums and discounts on mortgage-backed securities and asset-backed securities are amortized or accrued using the constant yield method whichconsiders anticipated prepayments at the date of purchase. To the extent that the estimated lives of such securities change as a result of changes in estimatedprepayment rates, the adjustments are included in net investment income using the retrospective method.Realized investment gains or losses are determined on a specific identification basis. Interest income is recognized as earned, and dividend income isrecognized on the ex-dividend date.The Company evaluates its available-for-sale fixed maturity securities regularly to determine whether there are declines in value that are other-than-temporary. The Company’s outside investment managers assist the Company in this evaluation. When the Company determines that a security hasexperienced an other-than-temporary impairment, the impairment loss is recognized as a realized investment loss. The factors that the Company considers inevaluating whether such an other-than-temporary impairment has occurred include the amount and percentage that fair value is below amortized cost and thelength of time that fair value has been below amortized cost. In addition, the Company considers the credit quality rating of the security, with a specialemphasis on securities downgraded below investment grade. Management does not intend to sell available-for-sale fixed maturity securities in an unrealizedloss position, and it is not “more likely than not” that the Company will be required to sell these securities before a recovery in fair value to their amortizedcost basis occurs.Effective January 1, 2018, with the adoption of ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement ofFinancial Assets and Financial Liabilities, equity securities (except those accounted for under the equity method of accounting or those that result inconsolidation of the investee) are measured at fair value with changes in fair value recognized in net investment income. Prior to the adoption of ASU 2016-01, changes in the fair value of equity securities were recognized net of taxes as a component of accumulated other comprehensive income.Bank Loan Participations Held-for-Investment and Allowance for Credit LossesBank loan participations held-for-investment are managed by a specialized outside investment manager and are generally stated at their outstandingunpaid principal balances net of unamortized premiums or discounts and net of any allowance for credit losses. Interest income is accrued on the unpaidprincipal balance. Discounts and premiums are amortized to income using the interest method.Generally, the accrual of interest on a bank loan participation is discontinued when the contractual payment of principal or interest has become 90 dayspast due or management has serious doubts about further collectability of principal or interest. A bank loan participation may remain on accrual status if it isin the process of collection and is either guaranteed or well secured. Interest received on nonaccrual loans generally is reported as investment income. Therewere no bank loans on nonaccrual status at December 31, 2018 or 2017.Generally, bank loan participations are restored to accrual status when the obligation is brought current, has performed in accordance with thecontractual terms for a reasonable period of time, and the ultimate collectability of the total contractual principal and interest is no longer in doubt.​The allowance for credit losses is maintained at a level believed adequate by management to absorb estimated probable credit losses. Management’speriodic evaluation of the adequacy of the allowance is based on consultations and advice of the Company’s specialized investment manager, known andinherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, currenteconomic conditions, and other relevant factors. When an observable market price for a loan is available, the Company has recorded an allowance equal tothe difference between the fair value and the amortized cost of bank loans that it has determined to be impaired as a practical expedient for an estimate ofprobable future cash flows to be collected on those bank loans. If an observable market price for a loan is not available, the Company records an allowanceequal to the difference between the present value of expected future cash flows discounted at the loan’s effective interest rate and the amortized cost of theloan. Bank loans are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.Other Invested AssetsOther invested assets at December 31, 2018 and 2017 include the Company’s interests in private debt and equity investments. The investments areprimarily focused in renewable energy, limited partnerships, and bank holding companies. Equity interests in various limited liability companies (“LLCs”)and limited partnerships are accounted for under the equity method, as the Company has determined that the equity method best reflects its economic interestin the underlying equity investment. For certain note agreements, original discounts and commitment fees received are recognized over the terms of the notesunder the effective interest method.F-10TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016Short-Term InvestmentsShort-term investments are carried at cost, which approximates fair value. Short-term investments have maturities greater than three months but less thanone year at the date of purchase.Cash EquivalentsThe Company considers highly liquid investments with maturities of three months or less at the date of purchase to be cash equivalents.Direct Written PremiumsDirect written premiums are earned on a pro rata basis over the terms of the policies, generally 12 months. The portion of premiums written applicable tothe unexpired terms of the policies in force is recorded as unearned premiums. Policies are accounted for on an individual basis, with no aggregation bycounterparty.Assumed Reinsurance PremiumsAssumed reinsurance written premiums include amounts reported by brokers and ceding companies, supplemented by the Company’s own estimates ofpremiums when reports have not been received. Premiums on the Company’s excess of loss and pro rata reinsurance contracts are estimated when the businessis underwritten. For excess of loss contracts, the deposit premium, as defined in the contract, is generally recorded as an estimate of premiums written at theinception date of the treaty. Estimates of premiums written under pro rata contracts are recorded in the period in which the underlying risks are expected tobegin and are based on information provided by the brokers and the ceding companies.Reinsurance premium estimates are reviewed by management periodically. Any adjustment to these estimates is recorded in the period in which itbecomes known.​Reinsurance premiums assumed are earned over the terms of the underlying policies or reinsurance contracts. Contracts and policies written on a “lossesoccurring” basis cover claims that may occur during the term of the contract or policy, which is typically 12 months. Accordingly, the premium is earnedevenly over the term. Contracts which are written on a “risks attaching” basis cover claims which attach to the underlying insurance policies written duringthe terms of such contracts. Premiums earned on such contracts usually extend beyond the original term of the reinsurance contract, typically resulting inrecognition of premiums earned over a 24-month period in proportion to the level of underlying exposure. Contracts are accounted for on an individual basis,with no aggregation by counterparty.Premiums Receivable and Agents’ Balances, NetPremiums receivable and agents’ balances are carried at face value net of any allowance for doubtful accounts. The allowance for doubtful accountsrepresents an estimate of amounts considered uncollectible based on the Company’s assessment of the collectability of receivables that are past due.Receivables greater than 90 days past due were $4.5 million and $2.6 million at December 31, 2018 and 2017, respectively. The allowance for doubtfulaccounts was $3.9 million and $2.8 million at December 31, 2018 and 2017, respectively. Bad debt expense was $1.5 million for the year endedDecember 31, 2018, $1.0 million for the year ended December 31, 2017, and $813,000 for the year ended December 31, 2016. Receivables written off againstthe allowance for doubtful accounts totaled $313,000 for the year ended December 31, 2018, $408,000 for the year ended December 31, 2017, and $1.5million for the year ended December 31, 2016. Account balances are charged off against the allowance after all means of collection have been exhausted andthe potential for recovery is considered remote.Deferred Policy Acquisition CostsCosts which are incrementally or directly related to the successful acquisition of new or renewal insurance business are deferred. These deferred costs areprimarily commissions to agents, ceding commissions paid on reinsurance assumed, premium taxes, and the portion of underwriting fixed compensation andpayroll related fringe benefits directly related to an insurance contract that has been acquired, net of ceding commissions related to reinsurance ceded.Amortization of such policy acquisition costs is charged to expense in proportion to premium earned over the estimated policy life. To the extent thatunearned premiums on existing policies are not adequate to cover projected related costs and expenses, deferred policy acquisition costs are charged toearnings. The Company considers anticipated investment income in determining whether a premium deficiency exists.Reinsurance and Adjustable Features of Insurance and Reinsurance ContractsCertain premiums and losses are ceded to other insurance companies or assumed from other insurance companies under various excess of loss and quota-share reinsurance contracts. The Company enters into ceded reinsurance contracts to limit itsF-11TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016exposure to large losses, to limit exposure on new lines of insurance written by the Company, and to provide additional capacity for growth.Premiums, commissions, and losses and loss adjustment expenses on reinsured business are accounted for on a basis consistent with that used inaccounting for the original policies issued and the terms of the reinsurance contracts. Reinsurance recoverables and prepaid reinsurance premiums arereported as assets. Other amounts payable to insurance companies and reinsurers or receivable from insurance companies and reinsurers are netted where theright of offset exists. The Company receives ceding commissions in connection with certain ceded reinsurance. The ceding commissions are recorded as areduction of other operating expenses.Certain reinsurance contracts of the Casualty Reinsurance segment include provisions that adjust premiums or acquisition expenses based upon the lossexperience under the contracts. Premiums written and earned, as well as related acquisition expenses are recorded based upon the projected loss experienceunder the contracts.The Company’s Specialty Admitted Insurance segment writes insurance under specialty admitted fronting and program arrangements. The fronting andprogram arrangements may contain contractual provisions that adjust acquisition expenses based upon loss experience under the contracts. The specialtyadmitted fronting and program arrangements are significantly reinsured. These reinsurance contracts may also contain provisions that adjust premiums oracquisition expenses based upon the loss experience under the contracts. Premiums written and earned, as well as related acquisition expenses, are recordedbased upon the projected experience under the contracts.Other IncomeOther income is principally comprised of fee income earned on policies for which the Company has no exposure to underwriting risk. Fee income of$13.9 million, $17.0 million, and $10.1 million is included in other income for the years ended December 31, 2018, 2017, and 2016, respectively. Fees areearned on a pro rata basis over the service period of the underlying business. Policies are accounted for on an individual basis, with no aggregation bycounterparty.Income TaxesDeferred tax assets and deferred tax liabilities are provided for the future tax consequences attributable to temporary differences between the financialstatement carrying amounts of assets and liabilities and their respective U.S. tax basis. Deferred tax assets and liabilities are measured using enacted U.S.corporate tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred taxassets are reduced by a valuation allowance only when management believes it is more likely than not that some, or all, of the deferred tax assets will not berealized.GoodwillGoodwill is tested annually for impairment in the fourth quarter of each calendar year, or more frequently if events or changes in circumstances indicatethat the carrying amount of the Company’s reporting units, including goodwill, may exceed their fair values. The Company first assesses qualitative factorsin determining whether it is necessary to perform the quantitative goodwill impairment test. If management determines that it is more likely than not that thefair value of a reporting unit is less than the carrying value based on qualitative factors then they will perform the quantitative goodwill impairment test. Forthe quantitative goodwill impairment testing, the fair value of the reporting units is determined using a combination of a market approach and an incomeapproach which projects the future cash flows produced by the reporting units and discounts those cash flows to their present value. The projection of futurecash flows is necessarily dependent upon assumptions on the future levels of income as well as business trends, prospects, market, and economic conditions.The results of the two approaches are weighted to determine the fair value of each reporting unit. When the fair value is less than the carrying value of the netassets of the reporting unit, including goodwill, an impairment loss is charged to operations. To determine the amount of any goodwill impairment, theimplied fair value of reporting unit goodwill is compared to the carrying amount of that goodwill. The implied fair value of goodwill is determined in thesame manner as the amount of goodwill recognized in a business combination is determined. That is, the fair value of a reporting unit is assigned to all of theassets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination. Theexcess of the fair value of a reporting unit over the amounts assigned to its assets and liabilities is the implied fair value of goodwill.Intangible Assets, NetIntangible assets are initially recognized and measured at fair value. Specifically identified intangible assets with indefinite lives include trademarks andstate insurance licenses and authorities. Other specifically identified intangible assets with livesF-12TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016ranging from 7.0 to 27.5 years represent relationships with brokers. These intangible assets are amortized on a straight-line basis over their estimated usefullives.Intangible assets with indefinite useful lives are reviewed for impairment at least annually. In evaluating whether there has been impairment to theintangible asset, management determines the fair value of the intangible asset and compares the resulting fair value to the carrying value of the intangibleasset. If the carrying value exceeds the fair value, the intangible asset is written down to fair value, and the impairment is reported through earnings. TheCompany evaluates intangible assets with definite lives for impairment when impairment indicators are noted.Impairment of Long-Lived AssetsLong-lived assets with finite lives are tested for impairment whenever recognized events or changes in circumstances indicate the carrying value of theseassets may not be recoverable. If indicators of impairment are present, fair value is calculated using estimated future cash flows expected to be generated fromthe use of those assets. An impairment loss is recognized only if the carrying amount of a long-lived asset or asset group is not recoverable and exceeds its fairvalue. The carrying amount of a long-lived asset or asset group is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result fromthe use and eventual disposition of the asset or asset group. That assessment is based on the carrying amount of the asset or asset group at the date it is testedfor recoverability. An impairment loss is measured as the amount by which the carrying amount of a long-lived asset or asset group exceeds its fair value.Property and Equipment, NetProperty and equipment, which is included in “other assets” in the accompanying consolidated balance sheets, is reported at cost less accumulateddepreciation and is depreciated principally on a straight-line basis over the estimated useful lives of the depreciable assets, generally three to ten years.In the event the Company has been deemed the owner for accounting purposes of construction projects in lease arrangements, the estimated constructioncosts incurred to date are recorded as assets in property and equipment, net and included in “other assets” in the accompanying consolidated balance sheets.Upon occupancy of facilities under lease, the Company assesses whether arrangements qualify for sales recognition under the sale-leaseback accountingguidance. If the Company continues to be the deemed owner for accounting purposes, the cost of the building is depreciated over its estimated useful life.Reserve for Losses and Loss Adjustment ExpensesThe reserve for losses and loss adjustment expenses represents the estimated ultimate cost of all reported and unreported losses and loss adjustmentexpenses incurred and unpaid at the balance sheet date. The Company does not discount this reserve. The process of estimating the reserve for losses and lossadjustment expenses requires a high degree of judgment and is subject to a number of variables. The reserve for losses and loss adjustment expenses isestimated using individual case-basis valuations and statistical analyses. Those estimates are subject to the effects of trends in loss severity and frequency.The Company utilizes various actuarially-accepted reserving methodologies in determining the continuum of expected outcomes for its reserves. Thesemethodologies utilize various inputs, including management’s initial expected loss ratio (the ratio of losses and loss adjustment expenses incurred to netearned premiums), expected reporting patterns and payment patterns for losses and loss adjustment expenses (based on insurance industry data and theCompany’s own experience), and the Company’s actual paid and reported losses and loss adjustment expenses. An internal actuary reviews these results and(after applying appropriate professional judgment and other actuarial techniques that are considered necessary) presents recommendations to the Company’smanagement. Management uses this information and its judgment to make decisions on the final recorded reserve for losses and loss adjustment expenses.Management believes that the use of judgment is necessary to arrive at a best estimate for the reserve for losses and loss adjustment expenses given the long-tailed nature of the business generally written by the Company and the limited operating experience of the Casualty Reinsurance segment, the fronting andprogram business in the Specialty Admitted Insurance segment, and the commercial auto business in the Excess and Surplus Lines segment.Catastrophes of significant magnitude, including hurricanes and earthquakes, involve complex coverage issues. In estimating the reserve for losses andloss adjustment expenses for these catastrophes, management uses case reserve estimates based on information obtained from site inspections by theCompany’s adjustors and the terms of coverage provided in the policies. Management estimates reserves for incurred but not reported claims for thesecatastrophes using judgment based on an assessment of the Company’s property insurance exposures where the catastrophes occur and the Company’sprogress in settling claims.F-13TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016Although management believes that the reserve for losses and loss adjustment expenses is reasonable, it is possible that the Company’s actual incurredlosses and loss adjustment expenses will not develop in a manner consistent with the assumptions inherent in the determination of these reserves.Specifically, the Company’s actual ultimate loss ratio could differ from management’s initial expected loss ratio and/or the Company’s actual reportingpatterns for losses could differ from the expected reporting patterns. Accordingly, the ultimate settlement of losses and the related loss adjustment expensesmay vary significantly from the estimates included in the Company’s consolidated financial statements. These estimates are reviewed continually bymanagement and are adjusted as necessary as experience develops or new information becomes known; such adjustments are included in current operations.Share Based CompensationThe Company expenses the fair value of share equity awards over the vesting period of the award on a straight-line basis. The Black-Scholes-Mertonoption pricing model is used to value the options granted (see Note 11). Forfeitures of share-based awards are recognized as they occur. As the share basedcompensation expense is incurred, a corresponding increase to additional paid-in capital in shareholders’ equity is recognized. Share based compensationexpense is reflected in “other operating expenses” in the accompanying consolidated statements of income and comprehensive income.Financing ObligationsIn a lease arrangement where the Company made a minority investment in a partnership that was involved in the construction of a building, theCompany was deemed the owner for accounting purposes during the construction period. The Company recorded an asset for the amount of the total projectcosts and the related financing obligation is included in “other liabilities” in the accompanying consolidated balance sheets. Once construction wascompleted, the Company determined the arrangement did not qualify for sale-lease back treatment. Accordingly, the Company continues to reduce theobligation over the lease term as payments are made and depreciates the asset over its useful life. The Company does not report rent expense for the portion ofthe rent payment determined to be related to the assets which are owned for accounting purposes. Rather, this portion of the rent payment under the lease isrecognized as a reduction of the financing obligation and as interest expense.Upon adoption of ASU 2016-02, Leases (Topic 842) on January 1, 2019, the Company will derecognize assets of $22.6 million and liabilities of $30.9million associated with the above lease that was designated as build-to-suit under the previous guidance, and record a cumulative-effect adjustment toretained earnings of $8.3 million. The lease will be classified as an operating lease under the new standard. The Company will record a right-of-use asset andlease liability for the lease under the new standard.Variable Interest EntitiesEntities that do not have sufficient equity at risk to allow the entity to finance its activities without additional financial support or in which the equityinvestors, as a group, do not have the characteristic of a controlling financial interest are referred to as variable interest entities (“VIE”). A VIE is consolidatedby the variable interest holder that is determined to have the controlling financial interest (primary beneficiary) as a result of having both the power to directthe activities of a VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses or right to receive benefits from theVIE that could potentially be significant to the VIE. The Company determines whether it is the primary beneficiary of an entity subject to consolidationbased on a qualitative assessment of the VIE’s capital structure, contractual terms, nature of the VIE’s operations and purpose, and the Company’s relativeexposure to the related risks of the VIE on the date it becomes initially involved in the VIE. The Company reassesses its VIE determination with respect to anentity on an ongoing basis.The Company holds interests in VIEs through certain equity method investments included in “other invested assets” in the accompanying consolidatedbalance sheets. The Company has determined that it should not consolidate any of the VIEs as it is not the primary beneficiary in any of the relationships.Although the investments resulted in the Company holding variable interests in the entities, they did not empower the Company to direct the activities thatmost significantly impact the economic performance of the entities. The Company’s investments related to these VIEs totaled $29.8 million and $32.1million as of December 31, 2018 and 2017, respectively, representing the Company’s maximum exposure to loss.Earnings Per ShareBasic earnings per share excludes dilution and is computed by dividing net income by the weighted-average number of common shares outstanding forthe period. Diluted earnings per share reflects the dilution that could occur if securities or other contracts to issue common shares or common shareequivalents were exercised or converted into common shares as calculated using the treasury stock method. When inclusion of common share equivalentsincreases the earnings per share or reduces theF-14TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016loss per share, the effect on earnings is anti-dilutive, and the diluted net earnings or net loss per share is computed excluding these common shareequivalents.The following represents a reconciliation of the numerator and denominator of the basic and diluted earnings per share computations contained in theconsolidated financial statements.Net Income(Numerator) Weighted-AverageCommon Shares(Denominator) EarningsPer Share(in thousands, except per share data)Year ended December 31, 2018 Basic$63,830 29,887,990 $2.14Common share equivalents— 419,111 (0.03)Diluted$63,830 30,307,101 $2.11Year ended December 31, 2017 Basic$43,566 29,461,717 $1.48Common share equivalents— 811,432 (0.04)Diluted$43,566 30,273,149 $1.44Year ended December 31, 2016 Basic$74,471 29,063,075 $2.56Common share equivalents— 831,303 (0.07)Diluted$74,471 29,894,378 $2.49Common share equivalents relate to our outstanding equity awards (stock options and RSUs).For the years ended December 31, 2018 and 2017, common share equivalents of 180,329 shares and 174,380 shares, respectively, are excluded from thecalculations of diluted earnings per share as their effects are anti-dilutive. For the year ended December 31, 2016, all common share equivalents are dilutive.Adopted Accounting StandardsEffective January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606).The guidance applies to all companies that either enter into contracts with customers to transfer goods or services or enter into contracts for the transfer ofnonfinancial assets, unless those contracts are within the scope of other standards, such as insurance contracts. Under this guidance, a company recognizesrevenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled inexchange for those goods or services. Judgments required in adopting this update included identifying performance obligations in the contract, estimatingthe amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. Theadoption of ASU 2014-09 had no impact on reported fee income and there was no cumulative effect of initially applying the update.Effective January 1, 2018, the Company adopted ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement ofFinancial Assets and Financial Liabilities. Among other things, this ASU requires equity investments (except those accounted for under the equity methodof accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Uponadoption on January 1, 2018, the Company made a $4.7 million cumulative-effect adjustment to increase retained earnings and reduce accumulated othercomprehensive income. The adoption of ASU 2016-01 did not materially impact the Company's financial position, cash flows, or total comprehensiveincome. The Company's results of operations were impacted as changes in fair value of equity instruments are now presented in net income rather than othercomprehensive (loss) income. For the year ended December 31, 2018, the respective impact on net income was a reduction of $4.7 million ($0.16 reduction inbasic and diluted earnings per share).Effective January 1, 2018, the Company adopted ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification ofCertain Tax Effects from Accumulated Other Comprehensive Income. This update was issued as a result of the enactment of Public Law No. 115-97,informally titled the Tax Cuts and Jobs Act (the "Tax Act"), on DecemberF-15TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 201622, 2017. The ASU allows for the option to reclassify the stranded tax effects resulting from the implementation of the Tax Act out of accumulated othercomprehensive income and into retained earnings. As the adoption of ASU 2016-01 in 2018 resulted in the reclassification of the entire unrealized balanceon equity securities from accumulated other comprehensive income into retained earnings, only the stranded tax effects on the unrealized balances of fixedincome securities were impacted by the adoption of ASU 2018-02. The reclassification resulted in a $711,000 decrease to the Company's retained earningswith a corresponding increase to accumulated other comprehensive income in the first quarter of 2018.Prospective Accounting StandardsIn February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). Under current guidance for lessees, leases are only included on the balance sheet ifthey are designated as capital leases. This update will require the recognition of a right-of-use asset and a corresponding lease liability, discounted to thepresent value, for all leases that extend beyond 12 months. This ASU is effective for annual and interim reporting periods beginning after December 15, 2018.In the third quarter of 2018, the FASB issued ASU 2018-10 to clarify certain aspects of the guidance and ASU 2018-11, which provides an optionalalternative transition method to initially apply the new leases standard at the adoption date (collectively, with ASU 2016-02, Topic 842). Topic 842 nowallows for the use of either the modified retrospective adoption method or the alternative transition method. The Company has completed its evaluation andwill adopt the new standard on January 1, 2019 using a modified retrospective transition method, applying the transition provisions at the beginning of theperiod of adoption. The Company will elect the package of practical expedients permitted under the transition guidance within the new standard and will notelect to use hindsight in determining the lease term. The new standard will not be applied to leases with an initial term of 12 months or less. Upon adoption ofthe new standard, the Company will derecognize assets of $22.6 million and liabilities of $30.9 million associated with a lease that was designated as build-to-suit under the previous guidance, and record a cumulative-effect adjustment to retained earnings of $8.3 million. The lease will be classified as anoperating lease under the new standard. The Company will record right-of-use assets of $17.2 million and lease liabilities of $17.8 million at adoption of thenew standard. The new standard will not materially impact the Company's results of operations or cash flows, and will not impact compliance under thecovenants of our current credit agreements.In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on FinancialInstruments. Current GAAP delays the recognition of credit losses until it is probable a loss has been incurred. The update will require financial assetsmeasured at amortized cost, such as bank loan participations held for investment, to be presented at the net amount expected to be collected by means of anallowance for credit losses that runs through net income. Credit losses relating to available-for-sale debt securities will also be recorded through an allowancefor credit losses, with the amount of the allowance limited to the amount by which fair value is below amortized cost. This ASU is effective for annual andinterim reporting periods beginning after December 15, 2019. Upon adoption, this ASU will be applied using the modified-retrospective approach, by whicha cumulative-effect adjustment will be made to retained earnings as of the beginning of the first reporting period presented. The Company has not yetcompleted the analysis of how adopting this ASU will affect the Company’s financial statements.F-16TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 20162.InvestmentsThe Company's available-for-sale fixed maturity securities are summarized as follows:Cost orAmortizedCost GrossUnrealizedGains GrossUnrealizedLosses FairValue(in thousands)December 31, 2018 Fixed maturity securities: State and municipal$147,160 $3,422 $(1,287) $149,295Residential mortgage-backed208,869 577 (5,337) 204,109Corporate534,024 1,516 (10,772) 524,768Commercial mortgage and asset-backed199,528 310 (2,813) 197,025U.S. Treasury securities and obligations guaranteed by the U.S.government107,803 235 (845) 107,193Redeemable preferred stock2,025 — (213) 1,812Total fixed maturity securities, available-for-sale$1,199,409 $6,060 $(21,267) $1,184,202December 31, 2017 Fixed maturity securities: State and municipal$139,382 $5,587 $(603) $144,366Residential mortgage-backed160,379 723 (2,441) 158,661Corporate408,857 7,503 (2,639) 413,721Commercial mortgage and asset-backed182,595 714 (698) 182,611Obligations of U.S. government corporations and agencies35,948 — (101) 35,847U.S. Treasury securities and obligations guaranteed by the U.S.government79,476 37 (639) 78,874Redeemable preferred stock2,025 — (7) 2,018Total fixed maturity securities, available-for-sale$1,008,662 $14,564 $(7,128) $1,016,098The amortized cost and fair value of available-for-sale investments in fixed maturity securities at December 31, 2018 are summarized, by contractualmaturity, as follows:AmortizedCost FairValue(in thousands)One year or less$52,312 $52,100After one year through five years406,647 403,126After five years through ten years213,673 209,155After ten years116,355 116,875Residential mortgage-backed208,869 204,109Commercial mortgage and asset-backed199,528 197,025Redeemable preferred stock2,025 1,812Total$1,199,409 $1,184,202Actual maturities may differ for some securities because borrowers have the right to call or prepay obligations with or without penalties.F-17TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016The following table shows the Company’s gross unrealized losses and fair value for available-for-sale securities aggregated by investment category andthe length of time that individual securities have been in a continuous unrealized loss position:Less Than 12 Months 12 Months or More TotalFairValue GrossUnrealizedLosses FairValue GrossUnrealizedLosses FairValue GrossUnrealizedLosses(in thousands)December 31, 2018 Fixed maturity securities: State and municipal$19,733 $(284) $47,018 $(1,003) $66,751 $(1,287)Residential mortgage-backed49,180 (743) 105,778 (4,594) 154,958 (5,337)Corporate243,384 (5,089) 155,902 (5,683) 399,286 (10,772)Commercial mortgage and asset-backed106,423 (1,229) 51,805 (1,584) 158,228 (2,813)U.S. Treasury securities and obligations guaranteedby the U.S. government17,618 (51) 54,201 (794) 71,819 (845)Redeemable preferred stock1,812 (213) — — 1,812 (213)Total fixed maturity securities, available-for-sale$438,150 $(7,609) $414,704 $(13,658) $852,854 $(21,267)December 31, 2017 Fixed maturity securities: State and municipal$40,117 $(318) $10,662 $(285) $50,779 $(603)Residential mortgage-backed50,447 (261) 84,193 (2,180) 134,640 (2,441)Corporate113,464 (846) 66,954 (1,793) 180,418 (2,639)Commercial mortgage and asset-backed53,965 (244) 25,299 (454) 79,264 (698)Obligations of U.S. government corporations andagencies3,024 (1) 32,154 (100) 35,178 (101)U.S. Treasury securities and obligations guaranteedby the U.S. government50,760 (430) 26,707 (209) 77,467 (639)Redeemable preferred stock2,018 (7) — — 2,018 (7)Total fixed maturity securities, available-for-sale$313,795 $(2,107) $245,969 $(5,021) $559,764 $(7,128)The Company held securities of 222 issuers that were in an unrealized loss position at December 31, 2018 with a total fair value of $852.9 million andgross unrealized losses of $21.3 million. None of the fixed maturity securities with unrealized losses has ever missed, or been delinquent on, a scheduledprincipal or interest payment.At December 31, 2018, 100.0% of the Company’s fixed maturity security portfolio was rated “BBB-” or better (“investment grade”) by Standard &Poor’s or received an equivalent rating from another nationally recognized rating agency.Management concluded that none of the fixed maturity securities with an unrealized loss at December 31, 2018, 2017, and 2016 experienced an other-than-temporary impairment. Management does not intend to sell available-for-sale securities in an unrealized loss position, and it is not “more likely thannot” that the Company will be required to sell these securities before a recovery in their value to their amortized cost basis occurs.At December 31, 2017, management concluded that based on the severity and duration of the impairment associated with an equity security, thesecurity, had experienced an other-than-temporary impairment. Accordingly, the Company recorded an impairment loss of $1.5 million in 2017.Management concluded that none of the other equity securities with an unrealized loss at December 31, 2017 and 2016 experienced an other-than-temporaryimpairment.Bank loan participations generally have a credit rating that is below investment grade (i.e. below “BBB-” for Standard & Poor’s) at the date of purchase.These bank loans are primarily senior, secured floating-rate debt rated “BB”, “B”, or “CCC” by Standard & Poor’s or an equivalent rating from anothernationally recognized rating agency. These bank loans includeF-18TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016assignments of, and participations in, performing and non-performing senior corporate debt generally acquired through primary bank syndications and insecondary markets. Bank loans consist of, but are not limited to, term loans, the funded and unfunded portions of revolving credit loans, and other similarloans and investments. Management believed that it was probable at the time that these loans were acquired that the Company would be able to collect allcontractually required payments receivable.At December 31, 2017 and 2016, the Company held a participation in a loan issued by a company that produces and supplies power to Puerto Ricothrough a power purchase agreement with Puerto Rico Electric Power Authority (“PREPA”), a public corporation and governmental agency of theCommonwealth of Puerto Rico. Management concluded that the loan was impaired at December 31, 2016 and established an allowance for credit losses onthe loan of $177,000. After recording this impairment, the loan had a carrying value of $1.7 million at December 31, 2016 and unpaid principal of $2.0million. At December 31, 2017, management concluded that the loan was still impaired and established an allowance for credit losses of $759,000 to reducethe loan's carrying value to zero at December 31, 2017. The unpaid principal on the loan was $807,000 at December 31, 2017. In the first quarter of 2018, thefull outstanding principal on the loan was repaid and the Company recognized a realized gain of $807,000 on the repayment.Management concluded that none of the loans in the Company's bank loan portfolio were impaired as of December 31, 2018. At December 31, 2017, theaggregate allowance for credit losses was $3.2 million on five impaired loans with a total carrying value of $5.1 million and unpaid principal of $8.4 million.At December 31, 2016, the aggregate allowance for credit losses was $943,000 on five impaired loans with a total carrying value of $6.5 million and unpaidprincipal of $7.6 million. At December 31, 2017 and 2016, impairments in the bank loan portfolio largely reflect the impact of declining energy prices on themarket values of loans to oil and gas companies in the energy sector.The average recorded investment in impaired bank loans was $2.6 million, $5.8 million, and $6.4 million during the years ended December 31, 2018,2017, and 2016, respectively, and investment income of $125,000, $300,000, and $297,000 was recognized during the time that the loans were impaired.The Company recorded realized losses of $858,000 and $2.4 million, and realized gains of $415,000, during the years ended December 31, 2018, 2017, and2016, respectively, for changes in the fair value of impaired bank loans.At December 31, 2018, unamortized discounts on bank loan participations were $1.8 million, and unamortized premiums were $17,000. AtDecember 31, 2017, unamortized discounts on bank loan participations were $1.1 million, and unamortized premiums were $3,000.Major categories of the Company’s net investment income are summarized as follows:Year Ended December 31,2018 2017 2016(in thousands)Fixed maturity securities$34,129 $26,833 $25,917Bank loan participations18,279 17,388 14,486Equity securities5,240 5,045 5,617Other invested assets5,165 14,079 9,536Cash, cash equivalents, short-term investments, and other2,681 1,708 824Trading (losses) gains(4) (4) 18Gross investment income65,490 65,049 56,398Investment expense(4,234) (3,930) (3,760)Net investment income$61,256 $61,119 $52,638 Changes in unrealized gains or losses on securities held for trading are recorded as trading gains or losses within net investment income.

The transaction was accounted for under the purchase method of accounting, and goodwill andintangible assets were recognized by the Company as a result of the transaction.All of the Company’s goodwill is an asset of the Excess and Surplus Lines segment. The Company’s annual testing performed in the fourth quarter of2018, 2017 and 2016 indicated that no impairment of goodwill had occurred. The carrying amount of goodwill at December 31, 2018 and 2017 was $181.8million. Accumulated goodwill impairment losses were $99.6 million at December 31, 2018 and 2017. The most recent goodwill impairment losses occurredin 2010.Specifically identifiable intangible assets were acquired in the Merger. During the fourth quarters of 2018, 2017 and 2016, the indefinite-livedintangible assets for trademarks and insurance licenses and authorities were tested for impairment. Intangible assets for broker relationships that have specificlives and are subject to amortization were also reviewed for impairment. In the Specialty Admitted Insurance segment, Falls Lake General Insurance Companywas merged into Falls Lake National in the fourth quarter of 2018. In connection with this merger, Falls Lake General Insurance Company surrendered itslicenses to the various state insurance departments and reduced the carrying value of its intangible asset for "State Licenses" to $0. This caused a $200,000impairment in 2018 in the Specialty Admitted Insurance segment.

Input from the Company’sunderwriting and claims departments, including premium pricing assumptions and historical experience, are considered by the Company’s internal actuariesin estimating the initial expected loss ratios. The Company’s internal actuaries generally utilize five actuarial methods in their estimation process for thereserve for losses and loss adjustment expenses. These five methods utilize, to varying degrees, the initial expected loss ratio, detailed statistical analysis ofpast claims reporting and payment patterns, claims frequency and severity, paid loss experience, industry loss experience, and changes in market conditions,policy forms, exclusions, and exposures.In applying these methods to develop an estimate of the reserve for losses and loss adjustment expenses, our internal actuaries use judgment todetermine three key parameters for each accident year and line of business: the initial expected loss ratios, the incurred and paid loss development factors andthe weighting of the five actuarial methods to be used for each accident year and line of business. For the Excess and Surplus Lines and Specialty AdmittedInsurance segments, the internal actuaries perform a study on each of these parameters annually and make recommendations for the initial expected lossratios, the incurred and paid loss development factors and the weighting of the five actuarial methods by accident year and line of business. Members ofmanagement’s Reserve Committee review and approve the parameter review actuarial recommendations, and these approved parameters are used in thereserve estimation process for the next four quarters at which time a new parameter study is performed. For the Casualty Reinsurance segment, periodicassessments are made on a contract by contract basis with the goal of keeping the initial expected loss ratios and the incurred and paid loss developmentfactors as constant as possible until sufficient evidence presents itself to support adjustments. Method weights are generally less rigid for the CasualtyReinsurance segment given the heterogeneous nature of the various contracts, and the potential for significant changes in mix of business within individualtreaties.Different reserving methods are appropriate in different situations, and the Company’s internal actuaries use their judgment and experience to determinethe weighting of the methods to use for each accident year and each line of business and, for our Casualty Reinsurance segment, on a contract by contractbasis. For example, the current accident year has very little incurred and paid loss development data on which to base reserve projections. As a result, theCompany relies heavily on the initial expected loss ratio in estimating reserves for the current accident year. The Company generally sets the initial expectedloss ratio for the current accident year consistent with the internal actuaries’ pricing assumptions. We believe that this is a reasonable and appropriatereserving assumption for the current accident year since our pricing assumptions are actuarially driven and since the Company expects to make an acceptablereturn on the new business written. If actual loss emergence is better than our initial expected loss ratio assumptions, we will experience favorabledevelopment and if it is worse than our initial expected loss ratio assumptions, we will experience adverse development. Conversely, sufficient incurred andpaid lossF-24TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016development data is available for the oldest accident years, so more weight is given to this development data and less weight is given to the initial expectedloss ratio.The following table provides a reconciliation of the beginning and ending reserve balances for losses and loss adjustment expenses, net of reinsurance,to the gross amounts reported in the consolidated balance sheets:Year Ended December 31,2018 2017 2016(in thousands)Reserve for losses and loss adjustment expenses net of reinsurance recoverables at beginning ofperiod$989,825 $761,128 $653,534Add: Incurred losses and loss adjustment expenses net of reinsurance: Current year582,604 533,905 349,137Prior years17,672 21,472 (23,716)Total incurred losses and loss and adjustment expenses600,276 555,377 325,421Deduct: Loss and loss adjustment expense payments net of reinsurance: Current year86,355 103,205 39,473Prior years309,658 223,475 178,354Total loss and loss adjustment expense payments396,013 326,680 217,827Reserve for losses and loss adjustment expenses net of reinsurance recoverables at end of period1,194,088 989,825 761,128Add: Reinsurance recoverables on unpaid losses and loss adjustment expenses at end of period467,371 302,524 182,737Reserve for losses and loss adjustment expenses gross of reinsurance recoverables on unpaidlosses and loss adjustment expenses at end of period$1,661,459 $1,292,349 $943,865The foregoing reconciliation shows that $17.7 million of adverse development was experienced in 2018 on the reserve for losses and loss adjustmentexpenses held at December 31, 2017. This adverse reserve development included $15.0 million of adverse development in the Excess and Surplus Linessegment, including $20.7 million of adverse development in the commercial auto line of business that was primarily related to the 2016 contract year withone insured. The adverse development for commercial auto was partially offset by $5.7 million of favorable development in other Excess and Surplus Linesunderwriting divisions primarily from favorable development in the Excess Property underwriting division related to the 2017 hurricanes. Favorable reservedevelopment in the Specialty Admitted Insurance segment was $5.6 million and primarily came from accident years 2014 through 2016, as loss emergenceon our workers’ compensation business written prior to 2016 continued to develop more favorably than we had anticipated. In addition, $8.2 million ofadverse development occurred in the Casualty Reinsurance segment, with a majority of this adverse development coming from accident years at least fouryears old and treaties the Company has since non-renewed.The foregoing reconciliation shows that $21.5 million of adverse development was experienced in 2017 on the reserve for losses and loss adjustmentexpenses held at December 31, 2016. This adverse reserve development included $20.0 million of adverse development in the Excess and Surplus Linessegment, including $38.7 million of adverse development in the commercial auto line of business that was primarily related to the 2016 contract year withone insured. The adverse development for commercial auto was partially offset by favorable development of $18.6 million in other Excess and Surplus Linesunderwriting divisions primarily from the 2014 through 2016 accident years. This favorable development occurred because our actuarial studies at December31, 2017 for the Excess and Surplus Lines segment indicated that our loss experience on our casualty business excluding commercial auto continued to bebelow our initial expected ultimate loss ratios. The Company also experienced $2.7 million of favorable development on prior accident years in the SpecialtyAdmitted Insurance segment primarily from accident years 2010 through 2015, as losses on our workers’ compensation business written prior to 2016continued to develop more favorably than we had anticipated. The Casualty Reinsurance segment experienced $4.2 million of adverse development on prioraccident years primarily from two contracts from 2010 through 2013 that had higher than expected reported losses in 2017.The foregoing reconciliation shows that a $23.7 million redundancy developed in 2016 on the reserve for losses and loss adjustment expenses held atDecember 31, 2015.

In the Excess and Surplus Lines insurance segment and for fronting and programs in theSpecialty Admitted Insurance segment, the Company measures claim counts by claim event. The claim counts include all claims reported, even if theCompany does not establish a liability for the claim (i.e. reserve for loss and loss adjustment expenses).The Casualty Reinsurance segment typically assumes written premium under quota share arrangements. The Company typically does not have directaccess to claim frequency information underlying its assumed quota arrangements given the nature of that business. In addition, multiple claims are oftenaggregated by the ceding company before being reported to the Company. We do not use claim frequency information in the Casualty Reinsurance segmentin the determination of loss reserves or for other internal purposes. Based on these considerations, the Company does not believe providing claims frequencyinformation is practicable as it relates to the Casualty Reinsurance segment.The table below provides information on IBNR liabilities and claims frequency for: (1) the Excess and Surplus Lines segment split between commercialauto and all non commercial auto, and (2) the Specialty Admitted Insurance segment split between individual risk workers’ compensation and fronting andprograms:Excess and Surplus Lines — Excluding Commercial AutoAccident Year Incurred Lossesand Loss AdjExpenses IBNR Cumulative # ofReported Claims ($ in thousands)2009 $85,807 $2,188 1,6982010 71,312 2,890 1,3802011 106,536 3,919 1,4652012 101,271 4,339 1,7652013 83,855 10,248 2,2982014 84,074 12,440 2,1062015 102,434 21,215 2,4342016 126,050 44,649 2,7542017 131,897 79,836 2,6302018 167,004 135,018 3,242F-30TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016Excess and Surplus Lines — Commercial AutoAccident Year Incurred Lossesand Loss AdjExpenses IBNR Cumulative # ofReported Claims ($ in thousands)2013 $1,277 $1 542014 19,779 653 7,7612015 36,139 1,761 41,7232016 126,791 9,206 88,7462017 208,743 23,777 132,1912018 255,881 155,760 91,798Specialty Admitted - Individual Risk Workers’ CompensationAccident Year Incurred Lossesand Loss AdjExpenses IBNR Cumulative # ofReported Claims ($ in thousands)2009 $25,660 $— $1,4902010 27,099 699 1,6042011 36,593 1,786 1,8142012 28,186 1,020 1,3232013 10,909 510 5402014 12,704 422 8502015 18,376 2,177 9752016 18,050 5,010 8332017 22,071 6,434 1,0872018 16,432 5,422 1,170 F-31TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016Specialty Admitted — Fronting and ProgramsAccident Year Incurred Lossesand Loss AdjExpenses IBNR Cumulative # ofReported Claims ($ in thousands)2013 $52 $— 222014 3,228 238 8562015 8,974 1,076 1,3552016 14,682 3,203 2,7922017 24,271 10,083 6,5722018 21,758 16,058 5,874Casualty ReinsuranceAccident Year Incurred Lossesand Loss AdjExpenses IBNR ($ in thousands)2009 $27,168 $4312010 62,605 9372011 103,196 1,4272012 143,305 2,3972013 143,124 3,3302014 121,200 5,4502015 109,117 14,5952016 103,544 26,6752017 128,472 52,7852018 121,529 55,052The Company has not provided insurance coverage that could reasonably be expected to produce material levels of asbestos claims activity. In addition,management does not believe that the Company is exposed to environmental liability claims other than those which it has specifically underwritten andpriced as an environmental exposure.7.ReinsuranceThe Company remains liable to policyholders if its reinsurers are unable to meet their contractual obligations under applicable reinsurance agreements.To minimize exposure to significant losses from reinsurance insolvencies, the Company evaluates the financial condition of its reinsurers and monitorsconcentrations of credit risk. The Company’s reinsurance contracts generally require reinsurers that are not authorized as reinsurers under U.S. state insuranceregulations or that experience rating downgrades from rating agencies below specified levels to fund their share of the Company’s ceded outstanding lossesand loss adjustment expense reserves, typically through the use of irrevocable and unconditional letters of credit. In fronting arrangements, which theCompany conducts through its Specialty Admitted Insurance segment, the Company is subject to credit risk with regard to insurance companies who act asreinsurers for the Company in such arrangements. The Company customarily requires a collateral trust arrangement to secure the obligations of the insuranceentity for whom it is fronting.At December 31, 2018, the Company had reinsurance recoverables on unpaid losses of $467.4 million and reinsurance recoverables on paid losses of$18.3 million. All material reinsurance recoverables are from companies with A.M. Best Company ratings of “A-” (Excellent) or better, or are collateralizedwith letters of credit or by a trust agreement.At December 31, 2018, reinsurance recoverables on unpaid losses from the Company’s three largest reinsurers were $151.6 million, $47.9 million, and$44.1 million, representing 52.1% of the total balance.F-32TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016At December 31, 2018, prepaid reinsurance premiums ceded to three reinsurers totaled $30.8 million, $13.4 million, and $9.6 million, representing47.8% of the total balance.Premiums written, premiums earned, and losses and loss adjustment expenses incurred are summarized as follows:Year Ended December 31,2018 2017 2016(in thousands)Written premiums: Direct$1,027,222 $843,719 $549,700Assumed139,551 238,186 187,698Ceded(404,101) (315,279) (179,690)Net$762,672 $766,626 $557,708Earned premiums: Direct$990,221 $842,182 $483,166Assumed208,192 173,472 164,771Ceded(383,015) (274,545) (132,274)Net$815,398 $741,109 $515,663Losses and loss adjustment expenses: Direct$769,490 $626,318 $314,920Assumed131,346 142,818 108,029Ceded(300,560) (213,759) (97,528)Net$600,276 $555,377 $325,4218.Senior Debt​The Company has a $215.0 million senior revolving credit facility (as amended or amended and restated, the "2013 Facility”).

All awards issued under the Plans are issued at the discretion of the Board of Directors. Under the Legacy Plan, employees receivednon-qualified stock options. Options are outstanding under the Legacy Plan; however, no additional awards may be granted.Employees are eligible to receive non-qualified stock options, incentive stock options, share appreciation rights, performance shares, restricted shares,RSUs, and other awards under the 2014 LTIP. The maximum number of shares available for issuance under the 2014 LTIP is 4,171,150, and at December 31,2018, 1,724,865 shares are available for grant.Non-employee directors of the Company are eligible to receive non-qualified stock options, share appreciation rights, performance shares, restrictedshares, RSUs, and other awards under the 2014 Director Plan.

All of the outstandingoptions have an exercise price equal to the fair value of the underlying shares at the date of grant.The intrinsic value of each option is determined based on the difference between the fair value of the underlying share and the exercise price of theunderlying option. The total intrinsic value of options exercised during 2018, 2017 and 2016 was $4.6 million, $20.4 million and $10.2 million,respectively. The aggregate intrinsic value of options outstanding at December 31, 2018, 2017 and 2016 was $9.4 million, $18.5 million and $41.8 million,respectively. The aggregate intrinsic value of options exercisable at December 31, 2018, 2017 and 2016 was $8.5 million, $14.9 million and $28.3 million,respectively. The fair value used for calculating intrinsic values was $36.54, $40.01 and $41.55 at December 31, 2018, 2017 and 2016, respectively.The weighted-average remaining contractual life of the options outstanding and options exercisable at December 31, 2018 is 3.6 years and 3.3 years,respectively. There were no options granted in 2018. The weighted-average fair value of options granted during 2017 and 2016 was $8.21 and $5.55,respectively. The value of the options granted was estimated at the date of grant using the Black-Scholes-Merton option pricing model using the followingassumptions:Year Ended December 31,2017 2016Risk-free interest rate1.97% 1.23%Dividend yield2.85% 2.50%Expected share price volatility27.39% 25.00%Expected life5.0 years 5.0 yearsThe risk-free interest rate assumption is based on the five-year U.S. Treasury rate at the date of the grant. The dividend yield assumption was based upondividends expected to be declared over the life of the options at the date of grant. In 2017, the share price volatility assumption was based upon theCompany's 100-day realized volatility. In years prior to 2017, as a relatively new public company, the share price volatility assumption was based uponhistorical data for property-casualty companies which the Company deemed to be its peers. The expected life is determined using the simplified method,which factors in the average of the midpoint and the contractual term of each tranche in determining a single expected life. The simplified method is used asthe Company does not have sufficient historical exercise data to estimate an expected term.The Black-Scholes-Merton option pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictionsand are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including expected share price volatility.Because the Company’s share options have characteristics significantly different from those of traded options and because changes in the subjective inputassumptions can materially affect the fair value estimate, the existing models do not necessarily provide a reliable single measure of the fair value of suchshare options.F-37TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016RSUsThe following table summarizes RSU activity:Year Ended December 31,2018 2017 2016Shares Weighted-AverageGrant DateFair Value Shares Weighted-AverageGrant DateFair Value Shares Weighted-AverageGrant DateFair ValueUnvested, beginning of year178,882 $37.93 196,800 $24.38 234,922 $21.00Granted227,481 $39.74 137,034 $42.20 60,291 $32.03Vested(83,384) $37.61 (132,764) $24.24 (98,413) $21.00Forfeited(22,837) $40.21 (22,188) $26.06 — $—Unvested, end of year300,142 $39.22 178,882 $37.93 196,800 $24.38The vesting period of RSUs granted to employees range from one to five years and vest ratably over the respective vesting period, with the majorityvesting in three years.

The total fair value of shares vested in 2018, 2017and 2016 was $3.2 million, $5.5 million and $3.8 million, respectively. The holders of RSUs are entitled to dividend equivalents. The dividend equivalentsare settled in cash at the same time that the underlying RSUs vest and are subject to the same risk of forfeiture as the underlying shares. The fair value of theRSUs granted is based on the market price of the underlying shares.Compensation ExpenseShare based compensation expense is recognized on a straight line basis over the vesting period.

Those companies have received an undertaking from the Minister of Finance in Bermuda that, in the event ofany taxes being imposed, the Company will be exempt from taxation in Bermuda until March 2035.Distributions from the Company’s U.S. subsidiaries to its U.K. intermediate holding company, James River UK, are generally subject to a 5% dividendwithholding tax. James River Group paid a $21.1 million dividend to James River UK during 2017 and remitted $1.1 million of dividend withholding taxesto the U.S. tax authorities for the year ending December 31, 2017. No similar distributions occurred in 2018 or 2016.The Company’s U.S. subsidiaries are subject to federal, state and local corporate income taxes, and other taxes applicable to U.S. corporations. Inaddition, Carolina Re is subject to Federal income taxes as a result of its irrevocable election to be taxed as a U.S. domestic corporation under Section 953(d)of the Code. The Company’s U.S.-domiciled subsidiaries and Carolina Re file a consolidated U.S. federal income tax return.The Company’s U.S.-based subsidiaries are generally no longer subject to income tax examination by U.S. income tax authorities for the tax yearsending before January 1, 2015.Financial results for 2017 reflect provisional amounts related to the December 2017 enactment of the Tax Act.F-38TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016The Company did not record any amounts related to the changes in loss reserve discounting required by the Tax Act during 2017. These changesrequired the IRS to publish new discount factors based on loss payment patterns and interest rates determined under the Tax Act. During 2018, factors werepublished that allowed us to adjust our current and deferred tax liabilities based on the provisions of the Tax Act. The Tax Act has specific transitionprovisions associated with reserve discounting. The initial impact of the adjustments in 2018 was an increase to our deferred tax asset for the additionaldiscount as of December 31, 2017 of $8.8 million offset by an increase to our deferred tax liability of $8.8 million representing the 8 year transition provisionrequired by the Tax Act. During 2018, $1.1 million of this transition provision was recognized in our current provision and adjusted out of our deferred taxliability. There were other provisions of the Tax Act for which the Company finalized its estimates during 2018, and the impact of these was immaterial.The expected income tax provision computed from pre-tax income at the weighted-average tax rate has been calculated as the sum of the pre-tax incomein each jurisdiction multiplied by that jurisdiction’s applicable Federal statutory tax rate. Federal statutory tax rates of 0% and 21% have been used in 2018for Bermuda and the U.S., respectively. A Federal statutory rate of 35% has been used for the U.S. in 2017 and 2016. U.S. deferred taxes were remeasured at21% in 2017, down from 35% in 2016. U.S. income before Federal income taxes was $37.5 million, $50.1 million, and $18.3 million for the years endingDecember 31, 2018, 2017, and 2016, respectively. A reconciliation of the difference between the Company’s Federal income tax provision on U.S. incomeand the expected Federal tax provision on U.S. income using the weighted-average tax rate as well as a reconciliation to total tax expense is as follows:Year Ended December 31,2018 2017 2016(in thousands)Federal income tax expense at applicable statutory rates$7,875 $17,541 $6,401Tax-exempt investment income(272) (586) (643)Dividends received deduction(307) (792) (880)Excess tax benefits on share based compensation(567) (2,114) —Effect of tax rate reduction on deferred tax liability220 (3,498) —Other145 (90) (6)Federal income tax expense$7,094 $10,461 $4,872U.S. state income tax (benefit) expense(86) 65 —U.S. dividend withholding tax— 1,053 —Total income tax expense$7,008 $11,579 $4,872F-39TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016The significant components of net deferred tax assets (liabilities) at the corporate income tax rate of 21% for the years ended December 31, 2018 and2017 are summarized as follows:December 31,2018 2017(in thousands)Deferred tax assets: Accrued compensation expenses$2,456 $1,712Reserve for losses and loss adjustment expenses7,482 3,036Unearned premiums5,711 1,709Share based compensation1,352 1,143Allowance for doubtful accounts829 579Deferred policy acquisition costs— 1,509Property and equipment1,909 1,601Invested asset impairments— 791Other1,903 1,564Total deferred tax assets21,642 13,644Deferred tax liabilities: Intangible assets7,461 7,521Net unrealized gains887 2,578Deferred policy acquisition costs3,491 —Equity method investments8,582 8,348Other167 444Total deferred tax liabilities20,588 18,891Net deferred tax assets (liabilities)$1,054 $(5,247)Deferred income taxes have not been accrued with respect to certain undistributed earnings of foreign subsidiaries. If the earnings were to be distributed,as dividends or otherwise, such amounts may be subject to withholding taxation in the jurisdiction of the paying entity. The Company asserts that U.S.unremitted earnings as of December 31, 2018 will be permanently reinvested in the U.S. and, accordingly, no provision for withholding taxes arising inrespect to U.S. unremitted earnings has been made.The Company had no reserve for future tax contingencies or liabilities (“unrecognized tax benefits”) at December 31, 2018 or 2017.The U.S. imposes a 1% excise tax on reinsurance premiums paid to non-U.S. reinsurers with respect to risks located in the U.S. The rates of tax areestablished based on the nature of the risk, unless reduced by an applicable U.S. tax treaty. For the years ended December 31, 2018, 2017, and 2016, theCompany paid $823,000, $3.4 million, and $2.6 million, respectively, of federal excise taxes on its intercompany reinsurance transactions. The Companyalso paid excise taxes of $2.1 million, $2.2 million, and $1.6 million for the years ended December 31, 2018, 2017, and 2016, respectively, on writtenpremiums assumed from third-party insurers with respect to risks located in the U.S. These excise taxes are reflected as “other operating expenses” in theCompany’s consolidated income statements.F-40TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 201613.Other Operating Expenses and Other Expenses​Other operating expenses consist of the following:Year Ended December 31,2018 2017 2016(in thousands)Amortization of policy acquisition costs$111,103 $116,001 $101,624Other underwriting expenses of the insurance segments63,029 55,662 48,771Other operating expenses of the Corporate and Other segment 26,903 25,330 20,433Total$201,035 $196,993 $170,828Other expenses consist of the following:Year Ended December 31,2018 2017 2016(in thousands)Employee severance$1,386 $147 $1,492Income on leased building the Company is deemed to own for accounting purposes (seeNote 21)(623) (248) (196)Legal and professional services related to secondary share offerings337 535 281Other— 105 13Impairment of intangible asset200 — —Total$1,300 $539 $1,59014.Employee Benefits​The Company and its subsidiaries offer savings plans (the “Savings Plans”) which qualify under Section 401(k) of the U.S. Internal Revenue Code.Participants may contribute certain percentages of their pre-tax salary to the Savings Plans subject to statutory limitations.

For theyears ended December 31, 2018, 2017, and 2016, the expense associated with the Savings Plans totaled $2.9 million, $2.5 million, and $1.9 million,respectively.15.Commitments and Contingent Liabilities​The Company is a party to various lawsuits arising in the ordinary course of its operations. The Company believes that the ultimate resolution of thesematters will not materially impact its financial position, cash flows, or results of operations.The Company leases certain office space under operating leases that expire at various times and are subject to renewal options at market rates prevailingat the time of renewal. Rental expense for such leases was $4.6 million, $4.2 million, and $3.7 million for the years ended December 31, 2018, 2017, and2016, respectively.As of December 31, 2018, future minimum payments under non-cancelable operating leases for office space are as follows (in thousands):2019$3,94620203,79020213,50720222,63920232,376Thereafter4,705$20,963F-41TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016Included in the future minimum lease payments is $15.2 million related to the building constructed and owned by a partnership in which the Companyhas a minority investment (see Note 21).The Company’s Specialty Admitted Insurance segment entered into an agreement to lease certain policy management software. The five year leasebegan January 1, 2015. Lease expense for the year ended December 31, 2018 was $440,000 and total remaining payments of $468,000 will be paid in 2019.The Company’s reinsurance subsidiary, JRG Re, entered into three letter of credit facilities with banks as security to third-party reinsureds on reinsuranceassumed by JRG Re. JRG Re has established custodial accounts to secure these letters of credit. Under a $100.0 million facility, $52.6 million of letters ofcredit were issued through December 31, 2018 which were secured by deposits of $65.7 million. Under the 2013 Facility, $75.5 million of letters of creditwere issued through December 31, 2018 which were secured by deposits of $94.0 million. Under the 2017 Facility, $7.6 million of letters of credit wereissued through December 31, 2018 which were secured by deposits of $10.2 million. JRG Re has also established trust accounts to secure its obligations toselected reinsureds. The total amount deposited in the trust accounts for the benefit of third-party reinsureds was $301.5 million at December 31, 2018 (seeNote 2).The Company is a party to a set of insurance contracts with an insured group of companies under which the Company pays losses and loss adjustmentexpenses on the contract. The Company has indemnity agreements with this group of insured parties (non-insurance entities) and is contractually entitled toreceive reimbursement for a significant portion of the losses and loss adjustment expenses paid on behalf of the insured parties and other expenses incurredby the Company. The insured parties are required to collateralize all amounts currently due to the Company and to provide additional collateral sufficient tocover the amounts that may be recoverable under the indemnity agreement, including among other things case loss and loss adjustment expense reserves,IBNR loss and loss adjustment expense reserves, extra contractual obligations and excess of policy limits liabilities. This collateral is currently providedthrough a collateral trust arrangement established in favor of the Company by a captive insurance company affiliate of the insured group. At December 31,2018, the cash equivalent collateral held in the collateral trust arrangement was approximately $1,099.2 million, which exceeds the amount of claimsreceivable and unpaid reported losses and loss adjustment expenses outstanding. The Company has ongoing exposure to estimated losses and expenses onthese contracts growing at a faster pace than growth in our collateral balances. In addition, we have credit exposure if our estimates of future losses and lossadjustment expenses and other amounts recoverable, which are the basis for establishing collateral balances, are lower than actual amounts paid or payable.The amount of our credit exposure in any of these instances could be material. To mitigate these risks, we closely and frequently monitor our exposurecompared to our collateral held, and we request additional collateral when our analysis indicates that we have uncollateralized exposure.16.Other Comprehensive (Loss) IncomeThe following table summarizes the components of other comprehensive (loss) income:Year Ended December 31,2018 2017 2016(in thousands)Unrealized (losses) gains arising during the period, before U.S. income taxes$(23,201) $11,091 $2,790U.S. income taxes483 (2,374) (414)Unrealized (losses) gains arising during the period, net of U.S. income taxes(22,718) 8,717 2,376Less reclassification adjustment: Net realized investment (losses) gains(554) (835) 6,572U.S. income taxes39 333 (2,137)Reclassification adjustment for investment (losses) gains realized in net income(515) (502) 4,435Other comprehensive (loss) income$(22,203) $9,219 $(2,059)In addition to the $554,000 and $835,000 of realized investment losses and $6.6 million of realized investment gains on available-for-sale fixedmaturity securities for the years ended December 31, 2018, 2017, and 2016, the Company recognized $1.1 million of realized investment gains, $1.2 millionof realized investment losses, and $995,000 of realized investment gains in the respective years on its investments in bank loan participations. 2018 alsoincludes net realized losses of $6.0 million for the change in net unrealized gains on equity securities in accordance with the Company's adoption of ASU2016-01 effective January 1, 2018.F-42TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 201617.Segment Information​The Company has four reportable segments, three of which are separately managed business units and the fourth (“Corporate and Other”) includes theCompany’s remaining operations.

If a quoted marketprice is not available, the Company uses prices of similar securities. Values for U.S. Treasury and publicly-traded equity securities are generally based onLevel 1 inputs which use the market approach valuation technique. The values for all other fixed maturity securities (including state and municipal securitiesand obligations of U.S. government corporations and agencies) generally incorporate significant Level 2 inputs, and in some cases, Level 3 inputs, using themarket approach and income approach valuation techniques. There have been no changes in the Company’s use of valuation techniques since December 31,2016.The Company reviews fair value prices provided by its outside investment managers for reasonableness by comparing the fair values provided by themanagers to those provided by its investment custodian. The Company also reviews and monitors changes in unrealized gains and losses. The Company hasnot historically adjusted security prices. The Company obtains an understanding of the methods, models and inputs used by the investment managers andindependent pricing services, and controls are in place to validate that prices provided represent fair values. The Company’s control process includes, but isnot limited to, initial and ongoing evaluation of the methodologies used, a review of specific securities and an assessment for proper classification within thefair value hierarchy, and obtaining and reviewing internal control reports for our investment manager that obtains fair values from independent pricingservices.Assets measured at fair value on a recurring basis as of December 31, 2018 are summarized below: Fair Value Measurements UsingQuoted Pricesin ActiveMarkets forIdentical AssetsLevel 1 SignificantOtherObservableInputsLevel 2SignificantUnobservableInputsLevel 3 Total (in thousands)Fixed maturity securities, available-for-sale: State and municipal$— $149,295 $— $149,295Residential mortgage-backed— 204,109 — 204,109Corporate— 524,768 — 524,768Commercial mortgage and asset-backed— 192,797 4,228 197,025U.S. Treasury securities and obligations guaranteed by the U.S.government106,651 542 — 107,193Redeemable preferred stock— 1,812 — 1,812Total fixed maturity securities, available-for-sale$106,651 $1,073,323 $4,228 $1,184,202Equity securities: Preferred stock$— $60,740 $— $60,740Common stock16,674 757 214 17,645Total equity securities$16,674 $61,497 $214 $78,385Short-term investments$1,250 $80,716 $— $81,966F-46TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016Assets measured at fair value on a recurring basis as of December 31, 2017 are summarized below:Fair Value Measurements UsingQuoted Pricesin ActiveMarkets forIdentical AssetsLevel 1 SignificantOtherObservableInputsLevel 2SignificantUnobservableInputsLevel 3 Total(in thousands) Fixed maturity securities, available-for-sale: State and municipal$— $144,366 $— $144,366Residential mortgage-backed— 158,661 — 158,661Corporate— 413,721 — 413,721Commercial mortgage and asset-backed— 177,931 4,680 182,611Obligations of U.S. government corporations and agencies— 35,847 — 35,847U.S. Treasury securities and obligations guaranteed by the U.S.government78,265 609 — 78,874Redeemable preferred stock— 2,018 — 2,018Total fixed maturity securities, available-for-sale$78,265 $933,153 $4,680 $1,016,098Equity securities: Preferred stock$— $66,281 $— $66,281Common stock15,507 734 — 16,241Total equity securities$15,507 $67,015 $— $82,522Trading securities: Fixed maturity securities$— $3,808 $— $3,808Short-term investments$1,000 $35,804 $— $36,804A reconciliation of the beginning and ending balances of available-for-sale fixed maturity securities and equity securities measured at fair value on arecurring basis using significant unobservable inputs (Level 3) is shown below:Year Ended December 31,2018 2017 2016(in thousands)Beginning balance$4,680 $5,000$5,000Transfers out of Level 3— ——Transfers in to Level 3— ——Purchases214 ——Sales— ——Maturities and calls(452) (320) —Amortization of discount— ——Total gains or losses (realized/unrealized): Included in earnings— ——Included in other comprehensive income— ——Ending balance$4,442 $4,680$5,000The Company held one available-for-sale fixed maturity security at December 31, 2018 and 2017 for which the fair value was determined usingsignificant unobservable inputs (Level 3).

Transfers in to Level 3 occur when the Company is unable to obtain reliable prices for securities from pricing vendors and instead mustuse broker price quotes.There were no transfers between Level 1 and Level 2 during 2018, 2017 or 2016.

At December 31, 2017,bank loan participations held for investment that were determined to be impaired were written down to their fair value of $5.1 million.In the determination of the fair value for bank loan participations and certain high yield bonds, the Company’s investment manager endeavors to obtaindata from multiple external pricing sources. External pricing sources may include brokers, dealers and price data vendors that provide a composite pricebased on prices from multiple dealers. Such external pricing sources typically provide valuations for normal institutional size trading units of such securitiesusing methods based on market transactions for comparable securities, and various relationships between securities, as generally recognized by institutionaldealers. For investments in which the investment manager determines that only one external pricing source is appropriate or if only one external price isavailable, the relevant investment is generally recorded at fair value based on such price.Investments for which external sources are not available or are determined by the investment manager not to be representative of fair value are recordedat fair value as determined by the Company, with input from its investment managers and valuation specialists as considered necessary. In determining thefair value of such investments, the Company considers one or more of the following factors: type of security held, convertibility or exchangeability of thesecurity, redeemability of the security (including the timing of redemptions), application of industry accepted valuation models, recent trading activity,liquidity, estimates of liquidation value, purchase cost, and prices received for securities with similar terms of the same issuer or similar issuers. AtDecember 31, 2018, there were no investments for which external sources were unavailable to determine fair value. At December 31, 2017, there was onebank loan participation with an unpaid principal balance of $807,000 and a carrying value of zero for which external sources were unavailable to determinefair value.F-48TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016The carrying values and fair values of financial instruments are summarized below:December 31,2018 2017CarryingValue FairValue CarryingValue FairValue(in thousands)Assets Fixed maturity securities, available-for-sale$1,184,202$1,184,202 $1,016,098 $1,016,098Equity securities78,38578,385 82,522 82,522Fixed maturity securities, trading—— 3,808 3,808Bank loan participations held-for-investment260,972250,697 238,214 236,532Cash and cash equivalents172,457172,457 163,495 163,495Short-term investments81,96681,966 36,804 36,804Other invested assets – notes receivable13,25018,687 11,778 17,104Liabilities Senior debt118,300118,317 98,300 97,884Junior subordinated debt104,055117,057 104,055 116,569The fair values of fixed maturity securities and equity securities have been determined using quoted market prices for securities traded in the publicmarket or prices using bid or closing prices for securities not traded in the public marketplace.

In addition, state regulators may permit statutory accounting practices that differ from prescribed practices. Statutory accounting practicesprescribed or permitted by regulatory authorities for the Company’s insurance subsidiaries differ from U.S. GAAP. The principal differences between SAP andGAAP as they relate to the financial statements of the Company’s insurance subsidiaries are (a) policy acquisition costs are expensed as incurred under SAP,whereas they are deferred and amortized under GAAP, (b) certain assets are not admitted for purposes of determining surplus under SAP, (c) the classificationand carrying amounts of investments in certain securities are different under SAP and GAAP, and (d) the criteria for providing asset valuation allowances andthe methodologies used to determine the amount thereof are different under SAP and GAAP.F-49TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016Combined net income, statutory capital and surplus and minimum required statutory capital and surplus, as determined in accordance with statutoryaccounting practices, for the U.S. insurance subsidiaries as of December 31, 2018, 2017, and 2016 and for the years then ended are summarized as follows:2018 2017 2016(in thousands)Statutory net income$6,770 $31,881 $13,468Statutory capital and surplus241,668 219,132 184,859Minimum required statutory capital and surplus24,850 25,000 25,000Risk-Based Capital (“RBC”) requirements promulgated by the National Association of Insurance Commissioners require property-casualty insurers tomaintain minimum capitalization levels determined based on formulas incorporating various business risks of the insurance subsidiaries. As of December 31,2018, the insurance subsidiaries’ adjusted capital and surplus exceeds their authorized control level RBC.BermudaThe Company has two Bermuda-based insurance subsidiaries: JRG Re, a Class 3B insurer and Carolina Re, a Class 3A insurer. Under the BermudaInsurance Act 1978 and related regulations, an insurer must maintain minimum statutory capital and surplus at the greater of a minimum solvency margin(“MSM”) and the Enhanced Capital Requirement (“ECR”), which is the higher of the MSM and capital calculated by the Bermuda Solvency CapitalRequirement (“BSCR”) model or an approved internal model. The combined Bermuda insurers minimum statutory solvency margin required atDecember 31, 2018 was approximately $161.3 million (2017: $109.9 million). Actual combined statutory capital and surplus at December 31, 2018 was$439.4 million (2017: $409.2 million). The insurers had combined statutory net income of $86.5 million for 2018, $20.1 million for 2017, and $74.7 millionfor 2016. The ECR for the year ended December 31, 2017 was $275.4 million. The BSCR models for the year ended December 31, 2018 will not be filedwith the Bermuda Monetary Authority until April 30, 2019. The Company believes that the minimum statutory capital and surplus requirements will be met.The insurers must also maintain a minimum liquidity ratio in which the value of its relevant assets is not less than 75.0% of the amount of its relevantliabilities for general business. Relevant assets include cash and cash equivalents, fixed maturities, quoted alternative investments, accrued interest income,premiums receivable, losses recoverable from reinsurers, and funds withheld. The relevant liabilities include total insurance provisions and other liabilitiesless deferred income taxes and letters of credit, guarantees and other instruments. As of December 31, 2018 the minimum liquidity ratio requirements weremet.20.Dividend Restrictions​U.S.The insurance statutes of the U.S.-based insurance subsidiaries’ states of domicile limit the amount of dividends that they may pay annually without firstobtaining regulatory approval. Generally, the limitations are based on the greater of statutory net income for the preceding year or 10.0% of statutory surplusat the end of the preceding year. The maximum amount of dividends available to James River Group from its U.S. insurance subsidiaries during 2019 withoutregulatory approval is $24.2 million. However, U.S. insurance regulators have broad powers to prevent the reduction of statutory surplus to inadequate levelsand could refuse to permit the payment of dividends.Distributions from the Company’s U.S.-based subsidiaries to its U.K. intermediate holding company, James River UK, are generally subject to a 5%dividend withholding tax. The payment of any dividends by the Company’s U.S.-based subsidiaries directly to a Bermuda-based entity is subject to U.S.taxes at a 30.0% tax rate. JRG Holdings has determined that earnings of its U.S. subsidiaries have been and will be indefinitely reinvested in U.S. operations.BermudaThe Bermuda Insurance Act of 1978 prohibits an insurer from declaring or paying a dividend if it is in breach of its minimum solvency margin, itsenhanced capital requirement, or its minimum liquidity ratio, or if the declaration or payment of such dividend would cause such a breach. An insurer candeclare or pay dividends without prior regulatory approval up to 25% of the total statutory capital and surplus. At December 31, 2018, the maximumcombined amount of dividends that can be paid without prior regulatory approval was approximately $109.8 million. However, this dividend amount issubject to annual enhanced solvency requirement calculations.F-50TABLE OF CONTENTS​James River Group Holdings, LTD. and SubsidiariesNotes to Consolidated Financial StatementsYears ended December 2018, 2017, and 2016As of December 31, 2018, JRG Holdings had consolidated retained earnings of $79.8 million, all of which was available for the payment of dividends toshareholders.21.Other Related Party Transactions​The Company leases a commercial office building which houses the Company’s Richmond, Virginia operations under the terms of a non-cancelablelease from an entity with which it is affiliated. As a result of being deemed the owner for accounting purposes, the building is recorded as an asset and therelated financing obligation is recorded as a liability on the accompanying consolidated balance sheets. Since the arrangement did not qualify for sale-leaseback treatment upon completion of the asset’s construction, the Company continues to reduce the obligation over the lease term as payments are made anddepreciates the asset over its useful life. Both the financing obligation and the lease had initial 10-year terms which started in 2007. In 2015, the term of thelease and financing obligation were extended until 2026. The arrangements provide for 2% fixed annual rent increases.Upon adoption of ASU 2016-02, Leases (Topic 842) on January 1, 2019, the Company will derecognize assets of $22.6 million and liabilities of $30.9million associated with the above lease that was designated as build-to-suit under the previous guidance, and record a cumulative-effect adjustment toretained earnings of $8.3 million. The lease will be classified as an operating lease under the new standard. The Company will record a right-of-use asset andlease liability for the lease under the new standard.The Non-Executive Chairman of the Board and former Chief Executive Officer of the Company owns a plane that the Company periodically leases.Total fees paid by the Company for the use of this plane were $123,000, $314,000, and $246,000 for 2018, 2017, and 2016, respectively.Upon the Company’s initial public offering in 2014, the Company entered into a consulting agreement (the “Consulting Agreement”) with one of theCompany's Independent Directors. Under the terms of the Consulting Agreement, the director received $150,000 in 2016 and $37,500 in 2017 for investmentand other business consulting services. The Consulting Agreement was terminated on March 31, 2017.22.Subsequent EventsOn February 20, 2019, the Board of Directors declared a cash dividend of $0.30 per share.

AND SUBSIDIARIESCondensed Financial Information of RegistrantNotes to Condensed Financial Statements1.Accounting PoliciesOrganizationJames River Group Holdings, Ltd. (the “Company”) is an exempted holding company registered in Bermuda, organized for the purpose of acquiring andmanaging insurance and reinsurance entities.Basis of PresentationThe accompanying condensed financial statements have been prepared using the equity method. Under the equity method, the investment inconsolidated subsidiaries is stated at cost plus equity in undistributed earnings of consolidated subsidiaries since the date of acquisition. These condensedfinancial statements should be read in conjunction with the Company’s consolidated financial statements.Estimates and AssumptionsPreparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amountsreported in the financial statements and accompanying disclosures. Those estimates are inherently subject to change, and actual results may ultimately differfrom those estimates.Adopted Accounting StandardsEffective January 1, 2018, the Company adopted ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement ofFinancial Assets and Financial Liabilities. Among other things, this ASU requires equity investments (except those accounted for under the equity methodof accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Uponadoption on January 1, 2018, the Company made a $4.7 million cumulative-effect adjustment to increase retained earnings and reduce accumulated othercomprehensive income. The adoption of ASU 2016-01 did not materially impact the Company's financial position, cash flows, or total comprehensiveincome. The Company's results of operations were impacted as changes in fair value of equity instruments are now presented in net income rather than othercomprehensive (loss) income. For the year ended December 31, 2018, the respective impact on net income was a reduction of $4.7 million.Effective January 1, 2018, the Company adopted ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification ofCertain Tax Effects from Accumulated Other Comprehensive Income. This update was issued as a result of the enactment of Public Law No. 115-97,informally titled the Tax Cuts and Jobs Act (the "Tax Act"), on December 22, 2017. The ASU allows for the option to reclassify the stranded tax effectsresulting from the implementation of the Tax Act out of accumulated other comprehensive income and into retained earnings. As the adoption of ASU 2016-01 in 2018 resulted in the reclassification of the entire unrealized balance on equity securities from accumulated other comprehensive income into retainedearnings, only the stranded tax effects on the unrealized balances of fixed income securities were impacted by the adoption of ASU 2018-02. Thereclassification resulted in a $711,000 decrease to the Company's retained earnings with a corresponding increase to accumulated other comprehensiveincome in the first quarter of 2018.F-57TABLE OF CONTENTSSCHEDULE III​JAMES RIVER GROUP HOLDINGS, LTD.
