Accounting Policies [Abstract]
Accounting Policies	1. Accounting Policies Organization James River Group Holdings, Ltd. (referred to as “JRG Holdings” or the “Company”) is an exempted holding company registered in 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 a Bermuda-based reinsurance company, as described below: · James River Group, Inc. (“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 operations and maintains all of the outstanding U.S. debt. · 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 Insurance Company (“Stonewood Insurance”), a North Carolina domiciled company, and Falls Lake General Insurance Company, an Ohio domiciled company. Falls Lake National began writing specialty admitted program business in late 2013. · Stonewood Insurance is a workers’ compensation insurance company that writes insurance primarily for the residential construction and light manufacturing industries. Stonewood Insurance writes individual risk workers’ compensation coverage in North Carolina, Virginia, South Carolina, and Tennessee. · JRG Reinsurance Company, Ltd. (“JRG Re”) was formed in 2007 and commenced operations in 2008. JRG Re, a Bermuda domiciled reinsurer, provides reinsurance to U.S. third parties and to the Company’s U.S.-based insurance subsidiaries. Basis of Presentation The accompanying condensed consolidated financial statements and notes have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and do not contain all of the information and footnotes required by U.S. GAAP for complete financial statements. The condensed consolidated financial statements include the results of the Company and its subsidiaries from their respective dates of inception or acquisition, as applicable. Readers are urged to review the Company’s 2014 audited consolidated financial statements for a more complete description of the Company’s business and accounting policies. In the opinion of management, all adjustments necessary for a fair presentation of the condensed consolidated financial statements have been included. Such adjustments consist only of normal recurring items. Interim results are not necessarily indicative of results of operations for the full year. The consolidated balance sheet as of December 31, 2014 was derived from the Company’s audited annual consolidated financial statements. Intercompany transactions and balances have been eliminated. Estimates and Assumptions Preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying disclosures. Those estimates are inherently subject to change, and actual results may ultimately differ from those estimates. Variable Interest Entities Entities that do not have sufficient equity at risk to allow the entity to finance its activities without additional financial support or in which the equity investors, as a group, do not have the characteristic of a controlling financial interest are referred to as variable interest entities (“VIE”). A VIE is consolidated by the variable interest holder that is determined to have the controlling financial interest (primary beneficiary) as a result of having both (1) the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and (2) the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company determines whether it is the primary beneficiary of an entity subject to consolidation based on a qualitative assessment of the VIE’s capital structure, contractual terms, nature of the VIE’s operations and purpose, and the Company’s relative exposure 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 an entity on an ongoing basis. The Company holds interests in VIEs through certain equity method investments in limited liability companies (“LLCs”) included in “other invested assets” in the accompanying condensed consolidated balance 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 that most significantly impact the economic performance of the entities. The Company’s investments related to these VIEs totaled $26.0 million and $25.1 million as of September 30, 2015 and December 31, 2014, respectively, representing the Company’s maximum exposure to loss.

None of the fixed maturity securities with unrealized losses has ever missed, or been delinquent on, a scheduled principal or interest payment. At September 30, 2015, 87.1% of the Company’s fixed maturity security portfolio was rated “A-“ or better by Standard & Poor’s or received an equivalent rating from another nationally recognized rating agency. Fixed maturity securities with ratings below investment grade by Standard & Poor’s or another nationally recognized rating agency at September 30, 2015 had an aggregate fair value of $10.3 million and an aggregate net unrealized loss of $4.7 million. The Company previously held two municipal bonds issued by the Commonwealth of Puerto Rico. Puerto Rico’s weak economic conditions and heavy debt burden heightened the risk of default on the bonds and management concluded that the bonds, which had been downgraded to below investment grade, were other-than-temporarily impaired at June 30, 2014. The Company recognized impairment losses of $1.4 million on these bonds for the year ended December 31, 2014 and $660,000 for the three months ended March 31, 2015. The bonds were sold during the second quarter of 2015 and a net realized gain of $22,000 was recognized on the sales. Management concluded that none of the other fixed maturity securities with an unrealized loss at September 30, 2015 or December 31, 2014 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 than not” that the Company will be required to sell these securities before a recovery in their value to their amortized cost basis occurs. Management also concluded that none of the equity securities with an unrealized loss at September 30, 2015 or December 31, 2014 experienced an other-than-temporary impairment. Management has evaluated the near-term prospects of these equity securities in relation to the severity and duration of the impairment, and management has the ability and intent to hold these securities until such time that they recover their fair value. The Company holds participations in two loans issued by companies that produce and supply power to Puerto Rico through power purchase agreements with Puerto Rico Electric Power Authority (“PREPA”), a public corporation and governmental agency of the Commonwealth of Puerto Rico. PREPA’s credit strength and ability to make timely payments has been impacted by the economic conditions in Puerto Rico, thus raising doubt about the companies’ ability to meet the debt obligations held by the Company. Management concluded that the loans were impaired at December 31, 2014 and established an allowance for credit losses on the loans of $752,000. After recording this impairment, these loans had a carrying value of $7.1 million at December 31, 2014 and unpaid principal of $8.4 million. At September 30, 2015, the allowance for credit losses on these loans was $501,000. The loans had a carrying value of $4.7 million at September 30, 2015 and unpaid principal of $5.6 million. The allowance for credit losses on these loans at September 30, 2014 was $742,000. A number of the Company’s bank loans are to oil and gas companies in the energy sector. The market values of these loans declined significantly in the fourth quarter of 2014 in response to declining energy prices. The declines in market values continued into 2015 and, after discussions with our independent investment manager, management decided to sell certain energy sector loans where there was an increased risk associated with the issuer’s ability to meet all principal and interest obligations as they became due. In total, the Company’s investments in bank loans to oil and gas companies in the energy sector had a carrying value of $21.0 million and an unrealized loss of $5.0 million at September 30, 2015. Management concluded that none of these loans were impaired as of September 30, 2015. There was no allowance for credit losses on these loans at September 30, 2014. Management also concluded that one non-energy sector loan held at September 30, 2015 should be considered impaired and an allowance for credit losses of $29,000 was established on the loan. After recording this impairment, the loan had a carrying value of $695,000 at September 30, 2015 and unpaid principal of $724,000. 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 “B” or “BB” by Standard & Poor’s or an equivalent rating from another nationally recognized rating agency. These bank loans include assignments of, and participations in, performing and non-performing senior corporate debt generally acquired through primary bank syndications and in secondary markets. Bank loans consist of, but are not limited to, term loans, the funded and unfunded portions of revolving credit loans, and other similar loans and investments. Management believed that it was probable at the time that these loans were acquired that the Company would be able to collect all contractually required payments receivable. Generally, the accrual of interest on a bank loan participation is discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collectability of principal or interest. A bank loan participation may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. Generally, bank loan participations are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. Interest received on nonaccrual loans generally is reported as investment income. There were no bank loans on nonaccrual status at September 30, 2015 or December 31, 2014. The allowance for credit losses is maintained at a level believed adequate by management to absorb estimated probable credit losses. Management’s periodic evaluation of the adequacy of the allowance is based on consultations and advice of the Company’s independent investment manager, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, current economic conditions, and other relevant factors. The Company generally records an allowance equal to the 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 of probable future cash flows to be collected on those bank loans. Bank loans are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The average recorded investment in impaired bank loans was $6.3 million and $4.1 million during the nine months ended September 30, 2015 and 2014, respectively. Investment income of $139,000 and $59,000, respectively, was recognized during the time within those periods that the loans were impaired. The Company recorded realized gains of $143,000 and $346,000, respectively, in the three months and nine months ended September 30, 2015 for changes in the fair value of impaired bank loans. In the three months and nine months ended September 30, 2014, the Company recorded realized gains of $221,000 and realized losses of $742,000, respectively, for changes in the fair value of impaired bank loans. Changes in unrealized gains or losses on securities held for trading are recorded as trading gains or losses within net investment income. Net investment income for the three months and nine months ended September 30, 2015 includes $21,000 and $4,000, respectively, of net trading gains of which $1,000 (for both the three and nine month periods) relates to securities held at September 30, 2015. The Company’s realized gains and losses are summarized as follows: Three Months Ended Nine Months Ended 2015 2014 2015 2014 (in thousands) Fixed maturity securities: Gross realized gains $ 130 $ 29 $ 1,417 $ 423 Gross realized losses (72 ) (91 ) (736 ) (1,503 ) 58 (62 ) 681 (1,080 ) Bank loan participations: Gross realized gains 421 736 953 1,714 Gross realized losses (496 ) (3 ) (4,150 ) (981 ) (75 ) 733 (3,197 ) 733 Equity securities: Gross realized gains - - - 88 Gross realized losses - - - (842 ) - - - (754 ) Short-term investments and other: Gross realized gains 4 1,362 52 1,362 Gross realized losses (4 ) - (9 ) (1,939 ) - 1,362 43 (577 ) Total $ (17 ) $ 2,033 $ (2,473 ) $ (1,678 ) Realized investment gains or losses are determined on a specific identification basis. The Company invests selectively in private debt and equity opportunities. These investments, which together comprise the Company’s other invested assets, are primarily focused in renewable energy, limited partnerships, and bank holding companies.

The LLCs are managed by an affiliate of the Company’s largest shareholder and the Company’s Chairman and Chief Executive Officer has invested in certain of these LLCs. The equity method is used to account for the Company’s LLC investments. Income for the LLCs primarily reflects adjustments to the carrying values of investments in renewable energy projects to their determined fair values. The fair value adjustments are included in revenues for the LLCs. Expenses for the LLCs are not significant and are comprised of administrative and interest expenses. The Company received cash distributions from these investments totaling $3.1 million and $3.3 million in the nine months ended September 30, 2015 and 2014, respectively. In March 2014, the Company sold its interest in one of the LLCs for $5.9 million and a $1.9 million realized loss was recognized on the sale. Investment income of $3.6 million was recognized on this investment in the three months ended March 31, 2014. (b) Investments in bridge loans for renewable energy projects. The notes, all with affiliates of the Company’s largest shareholder, generally mature in less than one year and carry primarily variable rates of interest ranging from 7.3% to 15.0%. Original discounts and commitment fees received are recognized over the terms of the notes under the effective interest method. During the nine months ended September 30, 2015, the Company invested a total of $36.3 million in these notes and has received maturities and partial repayments totaling $7.0 million. (c) Investments in limited partnerships that invest in concentrated portfolios of high yield bonds of companies undergoing financial stress, publicly-traded small cap equities, loans of middle market private equity sponsored companies, and equity tranches of collateralized loan obligations (CLOs). Income from the partnerships is recognized under the equity method of accounting. The Company has outstanding commitments to invest another $9.2 million in limited partnerships. (d) Net investment income for the nine months ended September 30, 2014 includes $57,000 related to a previously held equity investment in a bank holding company (“Predecessor Bank Holding Company”). On July 4, 2014, the Predecessor Bank Holding Company merged with and into another bank holding company (the “Surviving Bank Holding Company”). In exchange for its shares of the Predecessor Bank Holding Company, the Company received $354,000 in cash and $6.4 million of common shares in the Surviving Bank Holding Company, and the realized investment gain on the exchange was $1.4 million. The common shares of the Surviving Bank Holding Company are carried as available for-sale equity securities as they are publicly-traded and the Company does not have significant influence over the Surviving Bank Holding Company. The Company also holds $4.5 million of subordinated notes issued by a company that was substantially owned by the Predecessor Bank Holding Company (the “Bank Affiliate”). The $4.5 million of subordinated notes issued by the Bank Affiliate became debt of the Surviving Bank Holding Company. Interest on the notes, which mature on August 12, 2023, is fixed at 7.6% per annum. The Chairman and Chief Executive Officer of the Company previously served as Chairman of the Predecessor Bank Holding Company and the Bank Affiliate. Effective July 4, 2014, the Company’s Chairman and Chief Executive Officer became the Lead Independent Director of the Surviving Bank Holding Company. The Chairman and Chief Executive Officer of the Company is a former investor in the Predecessor Bank Holding Company and is now an investor in the Surviving Bank Holding Company. Additionally, one of the Company’s directors is a former investor in the Predecessor Bank Holding Company and is now an investor in the Surviving Bank Holding Company. In addition, this director was a lender to the Bank Affiliate and is now a lender to the Surviving Bank Holding Company. The Company’s Chief Financial Officer is a former investor in the Predecessor Bank Holding Company and the Surviving Bank Holding Company. (e) For the three months and nine months ended September 30, 2014, respectively, income of $3,000 and $184,000 was recognized on a $3.3 million note agreement with two property development companies. The note, which carried a fixed interest rate of 11.10%, was repaid in full on July 3, 2014. The Bank Holding Company also entered into note agreements with the same property development companies. On December 19, 2014, the Company purchased a $1.0 million certificate of deposit issued by the Surviving Bank Holding Company. The certificate of deposit, which matures on December 19, 2015, is carried as a short-term investment. Interest income of $1,000 and $4,000 was recognized on this investment for the three months and nine months ended September 30, 2015, respectively. Two of the Company’s directors are also directors of First Wind Capital, LLC (“First Wind”), which is an affiliate of the Company’s largest shareholder. At December 31, 2014, the Company held fixed maturity securities with a fair value of $12.6 million issued by First Wind. These securities were called in March 2015, resulting in a realized gain of $845,000. Also at December 31, 2014, the Company held a bank loan participation with a carrying value of $4.6 million from an affiliate of First Wind. The loan was repaid in full in January 2015.

This favorable reserve development included $10.1 million of favorable development in the Excess and Surplus Lines segment primarily from the 2014 and 2013 accident years. This favorable development occurred because our actuarial studies at September 30, 2015 for the Excess and Surplus Lines segment indicated that our loss experience on our casualty business continues to be below our initial expected loss ratios. The Company also experienced $2.0 million of favorable development on prior accident years for the Specialty Admitted Insurance segment. The favorable development in the Excess and Surplus Lines and Specialty Admitted Insurance segments was partially offset by $2.5 million of adverse reserve development in the Casualty Reinsurance segment, primarily related to one reinsurance relationship from the 2012 and 2011 underwriting years that experienced higher loss development in 2015 than expected. The Company experienced $15.4 million of favorable reserve development in the three months ended September 30, 2014 on the reserve for losses and loss adjustment expenses held at December 31, 2013. This reserve development included $12.0 million of favorable development in the Excess and Surplus Lines segment, primarily from the 2011 and 2010 accident years. This favorable development occurred because our actuarial studies at September 30, 2014 for the Excess and Surplus Lines segment indicated that our loss experience on our casualty business continued to be below our initial expected loss ratios. The Company also experienced $2.2 million of favorable development for the Specialty Admitted Insurance segment and $1.2 million of favorable development in the Casualty Reinsurance segment. A $14.6 million reserve redundancy developed in the nine months ended September 30, 2015 on the reserve for losses and loss adjustment expenses held at December 31, 2014.

Deemed ownership of the building also makes up $72,000 and $210,000 of other expenses for the three and nine months ended September 30, 2014. Other expenses for the three months ended September 30, 2014 include $1.8 million of legal, audit and other professional services related to the Company’s initial public offering and $600,000 in employee severance. Similarly, other expenses for the nine months ended September 30, 2014 include $1.9 million of legal, audit and other professional services related to the Company’s initial public offering, $600,000 in employee severance, and $183,000 of due diligence cost for an acquisition which we elected not to pursue.

Fair Value Disclosures [Abstract]
Fair Value Measurements	10. Fair Value Measurements Three levels of inputs are used to measure fair value of financial instruments: (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 in active 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. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. To measure fair value, the Company obtains quoted market prices for its investment securities. If a quoted market price is not available, the Company uses prices of similar securities. Values for U.S. Treasury and publicly-traded equity securities 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, and in some cases, Level 3 inputs, using the market approach and income approach valuation techniques. There have been no changes in the Company’s use of valuation techniques since January 1, 2014. The Company reviews fair value prices provided by its outside investment managers for reasonableness by comparing the fair values provided by the managers to those provided by its investment custodian. The Company also reviews and monitors changes in unrealized gains and losses. The Company has not historically adjusted security prices. The Company obtains an understanding of the methods, models and inputs used by the investment managers and independent pricing services, and controls are in place to validate that prices provided represent fair values. The Company’s control process includes, but is not limited to, initial and ongoing evaluation of the methodologies used, a review of specific securities and an assessment for proper classification within the fair value hierarchy, and obtaining and reviewing internal control reports for our investment manager that obtains fair values from independent pricing services. Assets measured at fair value on a recurring basis as of September 30, 2015 are summarized below: Fair Value Measurements Using Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Level 1 Level 2 Level 3 Total (in thousands) Available-for-sale securities: Fixed maturity securities: State and municipal $ – $ 119,853 $ – $ 119,853 Residential mortgage-backed – 136,712 – 136,712 Corporate – 340,422 - 340,422 Commercial mortgage and asset-backed – 136,292 - 136,292 Obligations of U.S. government corporations and agencies – 95,976 – 95,976 U.S. Treasury securities and obligations guaranteed by the U.S. government 56,534 731 – 57,265 Redeemable preferred stock – 1,960 – 1,960 Total fixed maturity securities 56,534 831,946 - 888,480 Equity securities: Preferred stock – 55,977 – 55,977 Common stock 17,742 734 - 18,476 Total equity securities 17,742 56,711 - 74,453 Total available-for-sale securities $ 74,276 $ 888,657 $ - $ 962,933 Trading securities: Fixed maturity securities $ 1,251 $ – $ – $ 1,251 Short-term investments $ 25,930 $ 24,295 $ – $ 50,225 Assets measured at fair value on a recurring basis as of December 31, 2014 are summarized below: Fair Value Measurements Using Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Level 1 Level 2 Level 3 Total (in thousands) Available-for-sale securities: Fixed maturity securities: State and municipal $ – $ 99,046 $ – $ 99,046 Residential mortgage-backed – 115,249 – 115,249 Corporate – 267,882 – 267,882 Commercial mortgage and asset-backed – 113,341 – 113,341 Obligations of U.S. government corporations and agencies – 101,275 – 101,275 U.S. Treasury securities and obligations guaranteed by the U.S. government 56,891 1,378 – 58,269 Redeemable preferred stock – 1,901 – 1,901 Total fixed maturity securities 56,891 700,072 – 756,963 Equity securities: Preferred stock – 49,601 – 49,601 Common stock 17,570 734 – 18,304 Total equity securities 17,570 50,335 – 67,905 Total available-for-sale securities $ 74,461 $ 750,407 $ – $ 824,868 Trading securities: Fixed maturity securities $ – $ 7,388 $ – $ 7,388 Short-term investments $ 58,507 $ 73,349 $ – $ 131,856 The beginning and ending balances of assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) was $0, and there was no activity (purchases, sales, transfers) involving Level 3 securities for the three months or nine months ended September 30, 2015 and 2014. Transfers out of Level 3 occur when the Company is able to obtain reliable prices from pricing vendors for securities for which the Company was previously unable to obtain reliable prices. Transfers to Level 3 occur when the Company is unable to obtain reliable prices for securities from pricing vendors and instead must use broker price quotes to value the securities. There were no transfers between Level 1 and Level 2 during the three months or nine months ended September 30, 2015 or 2014. The Company recognizes transfers between levels at the beginning of the reporting period. There were no realized gains or losses included in earnings for the three months or nine months ended September 30, 2015 attributable to the change in unrealized gains or losses relating to Level 3 assets valued at fair value on a recurring basis that are still held at September 30, 2015. The Company measures certain bank loan participations at fair value on a nonrecurring basis during the year as part of the Company’s impairment evaluation when loans are determined by management to be impaired. Assets measured at fair value on a nonrecurring basis are summarized below: Fair Value Measurements Using Quoted Prices In Active Markets for Identical Assets Level 1 Significant Other Observable Inputs Level 2 Significant Unobservable Inputs Level 3 Total (in thousands) September 30, 2015 Bank loan participations held-for-investment $ – $ – $ 695 $ 695 There were no assets measured at fair value on a nonrecurring basis at December 31, 2014. Bank loan participations held-for-investment that were determined to be impaired were written down to their fair value of $695,000 at September 30, 2015, and $7.9 million at September 30, 2014. The allowance for credit losses on bank loan participations was $530,000 at September 30, 2015 and $242,000 at December 31, 2014. The change in the allowance for credit losses on bank loan participations is included in net realized investment gains. In the determination of the fair value for bank loan participations and certain high yield bonds, the Company’s investment manager endeavors to obtain data from multiple external pricing sources. External pricing sources may include brokers, dealers and price data vendors that provide a composite price based on prices from multiple dealers. Such external pricing sources typically provide valuations for normal institutional size trading units of such securities using methods based on market transactions for comparable securities, and various relationships between securities, as generally recognized by institutional dealers. For investments in which the investment manager determines that only one external pricing source is appropriate or if only one external price is available, 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 recorded at fair value as determined by the investment manager. In determining the fair value of such investments, the investment manager considers one or more of the following factors: type of security held, convertibility or exchangeability of the security, redeemability of the security (including 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. At September 30, 2015, there were bank loan participations with an unpaid principal balance of $6.3 million and a carrying value of $5.5 million for which external sources were unavailable to determine fair value. At December 31, 2014, there were bank loan participations with an unpaid principal balance of $14.1 million and a carrying value of $12.7 million for which external sources were unavailable to determine fair value.

The fair values of cash and cash equivalents and short-term investments approximate their carrying values due to their short-term maturity. The fair values of other invested assets-notes receivable, senior debt, and junior subordinated debt at September 30, 2015 and December 31, 2014 were determined by calculating the present value of expected future cash flows under the terms of the note agreements or debt agreements, as applicable, discounted at an estimated market rate of interest at September 30, 2015 and December 31, 2014, respectively. For notes receivable maturing within one year, carrying value was used to approximate fair value. The fair values of bank loan participations held-for-investment, senior debt, and junior subordinated debt at September 30, 2015 and December 31, 2014 were determined using inputs to the valuation methodology that are unobservable (Level 3).

All awards issued under the Plans are issued at the discretion of the Board of Directors. Under the Legacy Plan, employees received non-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 share units (“RSUs”), and other awards under the 2014 LTIP. The maximum number of shares available for issuance under the 2014 LTIP is 3,171,150, and at September 30, 2015, 1,843,481 shares are available for grant.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements and notes have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and do not contain all of the information and footnotes required by U.S. GAAP for complete financial statements. The condensed consolidated financial statements include the results of the Company and its subsidiaries from their respective dates of inception or acquisition, as applicable. Readers are urged to review the Company’s 2014 audited consolidated financial statements for a more complete description of the Company’s business and accounting policies. In the opinion of management, all adjustments necessary for a fair presentation of the condensed consolidated financial statements have been included. Such adjustments consist only of normal recurring items. Interim results are not necessarily indicative of results of operations for the full year. The consolidated balance sheet as of December 31, 2014 was derived from the Company’s audited annual consolidated financial statements. Intercompany transactions and balances have been eliminated.
Estimates and Assumptions	Estimates and Assumptions Preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying disclosures. Those estimates are inherently subject to change, and actual results may ultimately differ from those estimates.
Variable Interest Entities	Variable Interest Entities Entities that do not have sufficient equity at risk to allow the entity to finance its activities without additional financial support or in which the equity investors, as a group, do not have the characteristic of a controlling financial interest are referred to as variable interest entities (“VIE”). A VIE is consolidated by the variable interest holder that is determined to have the controlling financial interest (primary beneficiary) as a result of having both (1) the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and (2) the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company determines whether it is the primary beneficiary of an entity subject to consolidation based on a qualitative assessment of the VIE’s capital structure, contractual terms, nature of the VIE’s operations and purpose, and the Company’s relative exposure 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 an entity on an ongoing basis. The Company holds interests in VIEs through certain equity method investments in limited liability companies (“LLCs”) included in “other invested assets” in the accompanying condensed consolidated balance 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 that most significantly impact the economic performance of the entities. The Company’s investments related to these VIEs totaled $26.0 million and $25.1 million as of September 30, 2015 and December 31, 2014, respectively, representing the Company’s maximum exposure to loss.
