Accounting Policies [Abstract]
Organization	Note 1. Organization NewStar Financial, Inc. is an internally-managed, commercial finance company with specialized lending platforms focused on meeting the complex financing needs of companies and private investors in the middle market. The Company and its investment management subsidiary, NewStar Capital, are registered investment advisers and provide asset management services to institutional investors. The Company manages several private credit funds that co-invest in loan origination through its leveraged finance lending platform. Through its wholly owned subsidiary, NewStar Capital, the Company also manages a series of funds structured as CLOs that invest primarily in broadly syndicated loans, as well as other sponsored funds and managed accounts that invest across various asset classes, including broadly syndicated loans, high yield bonds and distressed credits. Through its specialized lending platforms, the Company provides a range of senior secured debt financing options to mid-sized companies to fund working capital, growth strategies, acquisitions and recapitalizations, as well as, purchases of equipment and other capital assets. These lending activities require specialized skills and transaction experience, as well as a significant investment in personnel and operating infrastructure. To meet these demands, our loans and leases are originated directly by teams of credit-trained bankers and experienced marketing officers organized around key industry and market segments. These teams represent specialized lending groups that are supported by centralized credit management and operating platforms. This structure enables us to leverage common standards, systems, and industry and professional expertise across multiple businesses. The Company targets its marketing and origination efforts at private equity firms, mid-sized companies, corporate executives, banks, real estate investors and a variety of other referral sources and financial intermediaries to develop new customer relationships and source lending opportunities. The Company's origination network is national in scope and it targets companies with business operations across a broad range of industry sectors. The Company employs highly experienced bankers, marketing officers and credit professionals to identify and structure new lending opportunities and manage customer relationships. The Company believes that the quality of its professionals, the breadth of their relationships and referral networks, and their ability to develop creative solutions for customers position it to be a valued partner and preferred lender for mid-sized companies and private equity funds with middle market investment strategies. The Company's emphasis on direct origination is an important aspect of its marketing and credit strategy. The Company's national network is designed around specialized origination channels intended to generate a large set of potential lending opportunities. That allows the Company to be highly selective in its credit process and to allocate capital to market segments that we believe represent the most attractive opportunities. The Company's direct origination network also generates proprietary lending opportunities with yield characteristics that we believe would not otherwise be available through intermediaries. In addition, direct origination provides the Company with direct access to management teams and enhances its ability to conduct detailed due diligence and credit analysis of prospective borrowers. It also allows the Company to negotiate transaction terms directly with borrowers and, as a result, advise its customers on financial strategies and capital structures, which it believes benefits its credit performance. The Company typically provides financing commitments to companies in amounts that range in size from $10 million to $50 million. The size of financing commitments depends on various factors, including the type of loan, the credit characteristics of the borrower, the economic characteristics of the loan, and the Company's role in the transaction. The Company also selectively arranges larger transactions that it may retain on its balance sheet or syndicate to other lenders, which may include funds that it manages for third party institutional investors. By syndicating loans to other lenders and the Company's managed funds, it is able to provide larger financing commitments to its customers and generate fee income, while limiting our risk exposure to single borrowers. From time to time, however, the Company's balance sheet exposure to a single borrower exceeds $35 million. NewStar offers a set of credit products and services that have many common attributes, but which are highly specialized by lending group and market segment. Although both the Leveraged Finance and Business Credit lending groups structure loans as revolving credit facilities and term loans, the style of lending and approach to credit management is highly specialized. The Equipment Finance group broadens the Company's product offering to include a range of lease financing options. The operational intensity of each product also varies by lending group. Although, the Company operates as a single segment, it derives revenues from its asset management activities and four specialized lending groups that target market segments in which it believes that it has competitive advantages: · Leveraged Finance, provides senior, secured cash flow loans and, to a lesser extent, first out, second lien and unitranche loans, which are primarily used to finance acquisitions of mid-sized companies with annual cash flow (EBITDA) typically between $10 million and $50 million by private equity investment funds managed by established professional alternative asset managers; · Business Credit, provides senior, secured asset-based loans primarily to fund working capital needs of mid-sized companies with sales typically totaling between $25 million and $500 million; · Real Estate, provides first mortgage debt primarily to finance acquisitions of commercial real estate properties typically valued between $10 million and $50 million by professional commercial real estate investors; · Equipment Finance, provides leases, loans and lease lines to finance equipment purchases and other capital expenditures typically for companies with annual sales of at least $25 million; and · Asset Management, provides opportunities for qualified institutions to invest in a range of credit funds managed by the Company that employ credit-oriented strategies focused on middle market loans and liquid, tradeable credit.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Consolidation The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries (collectively, “NewStar”) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). All significant intercompany transactions have been eliminated in consolidation. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Estimates most susceptible to change in the near-term are the Company’s estimates of their allowance for credit losses, impairment of loans, recorded amounts of deferred income taxes, and impairment of goodwill and identifiable intangible assets. Prior Period Reclassifications Certain prior period disclosure amounts have been reclassified to conform to current period presentation. Cash and Cash Equivalents Cash and cash equivalents include all demand deposits held in banks and certain highly liquid instruments with original maturities of 90 days or less. Investments in Debt Securities Management determines the classification of securities at the time of purchase. If management has the intent and the Company has the ability at the time of purchase to hold securities until maturity, they are classified as held-to-maturity. Investment securities held-to-maturity are stated at amortized cost. Securities to be held for indefinite periods of time, but not necessarily to be held-to-maturity or on a long-term basis, are classified as available-for-sale and carried at fair value with unrealized gains or losses reported in other comprehensive income, net of applicable income taxes. The fair value of debt securities are based on quoted market prices, when available, at the reporting date for those or similar investments. When no market is available, the Company estimates fair value using various valuation tools, including cash flow analyses that utilize financial statements, business plans, as well as qualitative factors. The carrying values of all securities are adjusted for amortization of premiums and accretion of discounts over the shorter of the period to call or maturity of the related security using a method that approximates the interest method. Realized gains or losses on the sale of securities, if any, are determined using the amortized cost of the specific securities sold. Management evaluates securities for other-than-temporary impairment (“OTTI") on a periodic basis. Factors considered in determining whether an impairment is OTTI include: (1) the length of time and the extent to which the fair value has been less than amortized cost, (2) projected future cash flows, (3) the financial condition and near-term prospects of the issuers and (4) the intent and ability of the Company to hold the investment for a period of time sufficient to allow for any anticipated recovery in fair value. The Company records an OTTI loss in an amount equal to the entire difference between the fair value and amortized cost if (1) the Company intends to sell an impaired investment security, (2) it is more likely than not that the Company will be required to sell the investment security before its amortized costs or (3) for debt securities, the present value of expected future cash flows is not sufficient to recover the entire amortized cost basis. If an investment security is determined to be OTTI but the Company does not intend to sell the investment security, only the credit portion of the estimated loss is recognized in earnings, with the non-credit portion of the loss recognized in other comprehensive income. Loans Held-for-Sale Loans classified as held-for-sale consist of loans originated by the Company, intended to be sold or syndicated to third parties (including credit funds managed by the Company) or impaired loans for which a sale of the loan is expected as a result of a workout strategy. These loans are carried at the lower of aggregate cost, net of any deferred origination costs or fees, or fair value. Loans Loans are stated at the principal amount outstanding. Interest income is recorded on the accrual basis in accordance with the terms of the respective loan. Loans on which the accrual of interest has been discontinued are designated as nonaccrual loans. The accrual of interest on loans is typically discontinued when principal or interest payments are past due 90 days or when, in the opinion of management, it is probable it will be unable to collect contractual principal and interest in the normal course of business. When loans are placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income. Income on nonaccrual loans is subsequently recognized only to the extent that cash is received and the loan’s principal balance is deemed collectible. Nonrefundable loan fees and related direct costs associated with the origination of loans are deferred and included in loans, net in the consolidated balance sheet. The net deferred fees or costs are recognized as an adjustment to interest income over the contractual life of the loans using a method which approximates the interest method or taken into income when the related loans are paid off or sold. The Company accretes any discount from purchased loans into loan fee income as a yield adjustment over the contractual life of the loan. The amortization of loan fees is discontinued on non-accrual loans. Provision and Allowance for Credit Losses Our general allowance for credit losses covers probable losses in our loan and lease portfolio with respect to loans and leases that are not impaired and for which no specific impairment has been identified. A specific provision for credit losses is recorded with respect to loans for which it is probable that we will be unable to collect all amounts due in accordance with the contractual terms of the loan agreement for which there is impairment recognized. The Company employs a variety of internally developed and third-party modeling and estimation tools for measuring credit risk, which are used in developing an allowance for loan and lease losses on outstanding loans and leases. The Company’s allowance framework addresses economic conditions, capital market liquidity and industry circumstances from both a top-down and bottom-up perspective. The Company considers and evaluates a number of factors, including but not limited to, changes in economic conditions, credit availability, industry, loss emergence period, and multiple obligor concentrations in assessing both probabilities of default and loss severities as part of the general component of the allowance for loan and lease losses. On at least a quarterly basis, loans and leases are internally risk-rated based on individual credit criteria, including loan and lease type, loan and lease structures (including balloon and bullet structures common in the Company’s Leveraged Finance and Real Estate loans), borrower industry, payment capacity, location and quality of collateral if any (including the Company’s Real Estate loans). Borrowers provide the Company with financial information on either a monthly or quarterly basis. Ratings, corresponding assumed default rates and assumed loss severities are dynamically updated to reflect any changes in borrower condition or profile. For Leveraged Finance loans and Equipment Finance products, the data set used to construct probabilities of default in its allowance for loan losses model, Moody’s CRD Private Firm Database, primarily contains middle market loans that share attributes similar to the Company’s loans. The Company also considers the quality of the loan or lease terms and lender protections in determining a loan loss in the event of default. For Business Credit loans, the Company utilizes a proprietary model to risk rate the loans on a monthly basis. This model captures the impact of changes in industry and economic conditions as well as changes in the quality of the borrower’s collateral and financial performance to assign a final risk rating. The Company has also evaluated historical loss trends by risk rating from a comprehensive industry database covering more than twenty-five years of experience of the majority of the asset based lenders operating in the United States. Based upon the monthly risk rating from the model, the reserve is adjusted to reflect the historical average for expected loss from the industry database. For Real Estate loans, the Company employs two mechanisms to capture the impact of industry and economic conditions. First, a loan’s risk rating, and thereby its assumed default likelihood, can be adjusted to account for overall commercial real estate market conditions. Second, to the extent that economic or industry trends adversely affect a substandard rated borrower’s loan-to-value ratio enough to impact its repayment ability, the Company applies a stress multiplier to the loan’s probability of default. The multiplier is designed to account for default characteristics that are difficult to quantify when market conditions cause commercial real estate prices to decline. For consolidated variable interest entities to which the Company is providing transitional capital, we utilize a qualitative analysis which considers the business plans related to the entity, including expected hold periods, the terms of the agreements related to the entity, the Company’s historical credit experience, the credit migration of the entity’s loans in determining expected loss, as well as conditions in the capital markets. The Company provided capital on a transitional basis to the Arlington Fund. The Company deconsolidated the Arlington Fund on June 26, 2014. The Company did not recognize any losses on loans on the date of deconsolidation. The Company periodically reviews its allowance for credit loss methodology to assess any necessary adjustments based upon changing economic and capital market conditions. If the Company determines that changes in its allowance for credit losses methodology are advisable, as a result of changes in the economic environment or otherwise, the revised allowance methodology may result in higher or lower levels of allowance. In 2015, the Company enhanced its approach for determining the expected exposure at default to more precisely reflect loan and lease exposures at December 31, 2015. Given uncertain market conditions, actual losses under the Company’s current or any revised allowance methodology may differ materially from the Company’s estimate. Additionally, when determining the amount of the general allowance, the Company supplements the base amount with an environmental reserve amount which is governed by a score card system comprised of seven risk factors. The risk factors are designed based on those outlined in the Comptrollers of the Currency’s Allowance for Loan and Lease Losses Handbook. In 2015, the scoring system of the environmental reserve risk factors was recalibrated to align with the enhancement made to the approach for determining the exposure at default. The Company also performs a ratio analysis of comparable money center banks, regional banks and finance companies. While the Company does not rely on this peer group comparison to set the level of allowance for credit losses, it does assist management in identifying market trends and serves as an overall reasonableness check on the allowance for credit losses computation. A loan is considered impaired when it is probable that a creditor will be unable to collect all amounts due according to the contractual terms of the loan agreement. Impairment of a loan is based upon (i) the present value of expected future cash flows discounted at the loan’s effective interest rate, (ii) the loan’s observable market price, or (iii) the fair value of the collateral if the loan is collateral dependent, depending on the circumstances and our collection strategy. Impaired loans are identified based on the loan-by-loan risk rating process described above. Impaired loans include all non-accrual loans, loans with partial charge-offs and loans which are Troubled Debt Restructurings (see Note 4). It is the Company’s policy during the reporting period to record a specific provision for credit losses to cover the identified impairment on a loan. Impaired loans at December 31, 2015 were in Leveraged Finance, Equipment Finance and Real Estate over a range of industries impacted by the then current economic environment including the following: Media and Communications, Industrial, Commercial Real Estate, Other Business Services, Consumer/Retail, and Building Materials. For impaired Leveraged Finance and Equipment Finance loans, the Company measured impairment based on expected cash flows utilizing relevant information provided by the borrower and consideration of other market conditions or specific factors impacting recoverability. Such amounts are discounted based on original loan terms. For impaired Real Estate loans, the Company determined that the loans were collateral dependent and measured impairment based on the fair value of the related collateral utilizing recent appraisals from third-party appraisers, as well as internal estimates of collateral market value. Loans deemed to be uncollectible are charged off and the allowance is reduced by the charged off balance of the loan. The provision for credit losses and recoveries on loans previously charged off are added to the allowance. Deferred Financing Costs Deferred financing costs represent fees and other direct incremental costs incurred in connection with borrowings and term debt securitizations. These amounts are amortized using the straight-line method into earnings as interest expense ratably over the contractual term of the facility or the estimated life of the term debt securitization. Valuation of debt and equity linked instruments We account for the subordinated notes and associated warrants issued to Franklin Square as debt and equity-linked instruments. The warrants are freestanding, indexed to the Company's common stock and are classified as equity. They were initially recorded at relative fair value, with no subsequent re-measurement. The allocation of the proceeds from the issuance of debt and warrants to Franklin Square was determined using the relative fair value method. The allocation of proceeds to the warrants created a debt discount to the subordinated debt and will be amortized over the life of the subordinated notes. The subordinated debt is presented net of the debt discount. Property and Equipment Property and equipment are carried at cost and depreciated or amortized on a straight-line basis over the following useful lives: Leasehold improvements Shorter of estimated life or remaining lease term Furniture, fixtures and equipment 3-5 years Goodwill and Identified Intangible Assets Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Goodwill is not subject to amortization but tested for impairment at least annually utilizing a qualitative or quantitative approach or more frequently if events or circumstances occur that indicate that impairment may have occurred. As part of this evaluation, the Company makes a qualitative assessment of whether it is more likely than not that the fair value of an acquired asset is greater than its carrying amount. If the Company qualitatively concludes that it is more likely than not that the fair value of an acquired asset is greater than its carrying amount, no further testing is necessary. If, however, the Company qualitatively concludes that it is more likely than not that the fair value of an acquired asset is less than its carrying value, the Company performs a two-step quantitative impairment test to determine whether the asset is impaired. If impairment is deemed to have occurred, then an impairment loss would be recognized for the amount by which the carrying amount exceeds its fair value. Identified intangible assets are assets resulting from acquisitions that are being amortized over their estimated useful lives. The recoverability of identified intangible assets is evaluated for impairment at least annually. If impairment is deemed to have occurred, then an impairment loss would be recognized for the amount by which the carrying amount exceeds fair value. Earnings Per Share (“EPS”) The Company utilizes the two-class method to calculate earnings per share, which requires that unvested share-based awards be treated as participating securities in the computation of EPS. Under the two-class method, earnings are allocated to common shareholders and participating securities based upon the proportion of each to the total weighted average shares available. Basic earnings per common share is computed by dividing net earnings allocated to common shareholders by the weighted-average number of common shares outstanding. Diluted earnings reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in our earnings. Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability is not adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities. It is not a forced transaction. Market participants are buyers and sellers in the principal market that are independent, knowledgeable, able to transact and willing to transact. ASC 820, Fair Value Measurement Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company classifies all interest and penalties on recognized tax benefits as a part of income tax expense. As of December 31, 2015 and 2014, the Company did not have any significant accrued interest, penalties or uncertain tax positions. Fee Income Recognition Origination fees and costs are deferred and amortized as yield adjustments over the contractual life of the loans and investments. In connection with the prepayment of a loan or other debt product, any remaining unamortized net deferred fees for that loan are accelerated and, depending on the terms of the loan, there may be an additional fee charged based upon the prepayment and recognized in the period of the prepayment. Syndication and structuring fees are recognized in the period the service is completed and funds received as fee income. Asset Management Income NewStar Financial, Inc. earns asset management income for investment management services performed for managed credit funds related funds. NewStar accrues this income when earned, on a monthly basis, and classifies it as asset management income in the consolidated statements of operations. Stock Based Compensation The Company follows ASC 718, Share-Based Payment For awards granted, modified, repurchased or cancelled after January 1, 2006, the Company estimates the fair value of stock-based awards using the Black-Scholes valuation model, which requires the input of subjective assumptions, including expected term and expected price volatility. Changes in these assumptions can materially affect the calculated fair value of stock-based compensation and the related expense to be recognized. Further, for awards that contain performance measures and conditions, the Company makes an assessment, based on management’s judgment, of the probability of these conditions being satisfied, which affects the timing and the amount of expense to be recognized. If the Company’s judgment as to whether these conditions are probable of occurrence are not appropriate, the financial statements could be materially affected. Gain (loss) on sale of loans All loans sold to date have been sold without recourse. When loans are sold, a gain or loss is recognized to the extent that the sales proceeds plus unamortized fees and costs exceed or are less than the carrying value of the loans. Gains and losses are determined using the specific identification method. Equity and Cost Method Investments The Company may acquire a portion of the equity in borrowers. In cases where the Company has the ability to exercise significant influence over the borrower, it accounts for its equity interest under the equity method of accounting. Under the equity method of accounting, the Company recognizes its proportional share of the borrower’s GAAP net income in its results of operations. In cases where the equity of the underlying company has no value, and the borrower incurs losses, the Company will apply its proportional share of the GAAP loss against the principal of the outstanding loan to the borrower. In circumstances where we do not have substantial influence over the company, we account for the equity interest under the cost method of accounting. The equity interest is recorded on our books at its historical cost. The Company evaluates its equity and cost method investments for impairment by assessing whether the fair value of the equity interest has declined below its carrying value for a period we consider other-than-temporary. If it determines that a decline in fair value below our carrying value is other-than-temporary, an impairment is recognized to reduce the carrying value of the investment to its fair value. Derivative Instruments and Hedging Activities The Company accounts for derivatives and hedging activities on the balance sheet in either other assets or other liabilities at their respective fair values. On the date a derivative contract is entered into, the Company designates the derivative as either (1) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge) or as (2) a derivative trading instrument. For all hedging relationships the Company formally documents the hedging relationship and its risk-management objective and strategy for undertaking the hedge, the hedging instrument, the item, the nature of the risk being hedged, how the hedging instrument’s effectiveness in offsetting the hedged risk will be assessed, and a description of the method of measuring ineffectiveness. This process includes linking all derivatives that are designated as hedges to specific assets and liabilities on the balance sheet or to forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. Changes in the fair value of a derivative that is highly effective and that is designated and qualifies as a cash-flow hedge are recorded in other comprehensive income to the extent that the derivative is effective as a hedge, until earnings are affected by the variability in cash flows of the designated hedged item. The ineffective portion of the change in fair value of a derivative instrument that qualifies as a cash-flow hedge is reported in earnings. The Company discontinues hedge accounting prospectively when it is determined that the derivative is no longer effective in offsetting changes in the cash flows of the hedged item, the derivative expires or is sold, terminated, or exercised, the derivative is de-designated as a hedging instrument because it is unlikely that a forecasted transaction will occur, or management determines that designation of the derivative as a hedging instrument is no longer appropriate. In all situations in which hedge accounting is discontinued or was never applied, the Company continues to carry the derivative at its fair value on the balance sheet and recognizes any subsequent changes in its fair value in earnings. When hedge accounting is discontinued because it is probable that a forecasted transaction will not occur by the date (or within the time period) originally specified or within an additional two-month period of time thereafter, the Company recognizes immediately in earnings, gains and losses that were accumulated in other comprehensive income. Gains and losses on derivatives not designated as hedges, including any cash payments made or received, are reported as gain (loss) on derivatives in the accompanying consolidated statements of operations. Total Return Swap The Company is party to a total return swap (“TRS”). A TRS is a contract in which one party agrees to make periodic payments to another party based on the change in the market value of the assets underlying the TRS, in return for periodic payments based on a fixed or variable interest rate. The TRS effectively added leverage to our portfolio by providing investment exposure to underlying loans without owning or taking physical custody, in return for an interest-type payment to Citi. The TRS is recorded at fair value as an asset or liability with changes in fair value recorded as unrealized appreciation or depreciation. Realized gains or losses are recognized at the termination of the contract. Comprehensive Income (Loss), net of tax The Company records the change in fair value of cash flow hedge derivatives and unrealized gains and losses on available-for-sale securities in comprehensive income. Gains and losses on available-for-sale securities are reclassified to net income as the gains and losses are realized upon sale of the securities. Other than temporary impairment charges are reclassified to earnings at the time of the charge.

Acquisitions	Note 3. Acquisitions On October 7, 2015 (the “Acquisition Date”), the Company acquired 100% of the outstanding limited liability company interests of Boston-based Feingold O’Keeffe Capital, LLC (“FOC Partners”), a boutique credit manager. The Company operates FOC Partners as NewStar Capital, a wholly owned subsidiary of the Company. The primary reason for the acquisition was to expand the Company’s existing asset management capabilities. Total consideration paid in the FOC Partners acquisition consisted of $20.8 million in cash. The assets acquired and the liabilities assumed in the acquisition were recorded by the company at their estimated fair values as of the Acquisition Date. The excess of consideration paid over the fair value of identifiable net assets was recorded as goodwill in the consolidated financial statements. The following table presents the goodwill recorded in connection with the acquisition of FOC Partners: At Acquisition ($ in thousands) Total cash consideration paid $ 20,811 Fair value of identifiable net assets acquired 2,927 Goodwill $ 17,884 Goodwill represents the future economic benefits arising from net assets acquired that are not individually identified and separately recognized. The initial accounting is provisional and may be revised upon completion, however any potential changes are believed to be immaterial. Goodwill related to this acquisition will be deductible for income tax purpose. The acquisition date estimated fair values of the assets acquired and the liabilities assumed are summarized as follows: Fair Value ($ in thousands) Assets Acquired Cash and cash equivalents $ 1,628 Identified intangible assets 1,410 Other assets 2,054 Total assets acquired 5,092 Liabilities Assumed: Other liabilities 2,165 Total liabilities assumed 2,165 Identifiable net assets acquired $ 2,927 Fair values of the major categories of assets acquired and liabilities assumed were determined as follows: The fair value of cash and cash equivalents was assumed to approximate the carrying value of these accounts. The fair value of other assets includes accrued management, incentive fees, prepaid expenses, investment in hedge funds which the Company believes approximates carrying value. The fair value of the customer contracts included in identified intangible assets above, was determined using the excess earnings method under the income approach per ASC 820. Management projected net cash flows of each investment / collateral management agreement acquired for our best estimate of the useful life of the respective contracts. These net after-tax cash flows were discounted to present value as of the acquisition date. The customer contracts and related customer relationships was estimated at $1.4 million. The intangible assets are being amortized over its expected economic useful life which we estimated at acquisition to be no longer than 12 months. The fair value of the other liabilities include accrued expenses which the Company believes approximates the carrying value of these accounts. The Company's consolidated results of operations for the year ended December 31, 2015 include the $2.7 million of asset management income and $0.1 million of net income from the results of NewStar Capital from the acquisition date. Expenses related to the transaction amounted to $0.6 million and are included in general and administrative expenses. The following table summarized the unaudited pro forma results of operations as if the Company had acquired FOC Partners on January 1, 2014.

Loans Held-for-Sale, Loans and Leases, and Allowance for Credit Losses	Note 4. Loans Held-for-Sale, Loans and Leases, and Allowance for Credit Losses Although, the Company operates as a single segment, it derives revenues from its asset management activities and four specialized lending groups that target market segments in which it believes it has competitive advantages: · Leveraged Finance, provides senior, secured cash flow loans and, to a lesser extent, first out, second lien and unitranche loans, which are primarily used to finance acquisitions of mid-sized companies by private equity investment funds managed by established professional alternative asset managers; · Business Credit, provides senior, secured asset-based loans primarily to fund working capital needs of mid-sized companies; · Real Estate, provides first mortgage debt primarily to finance acquisitions of commercial real estate properties; and · Equipment Finance, provides leases, loans and lease lines to finance equipment purchases and other capital expenditures. The Company’s loan portfolio consists primarily of loans to medium-sized, privately-owned companies, most of which do not publicly report their financial condition. Compared to larger, publicly traded firms, loans to these types of companies may carry higher inherent risk. The companies that the Company lends to generally have more limited access to capital and higher funding costs, may be in a weaker financial position, may need more capital to expand or compete, and may be unable to obtain financing from public capital markets or from traditional sources, such as commercial banks. Loans classified as held-for-sale may consist of loans originated by the Company and intended to be sold or syndicated to third parties (including credit funds managed by the Company) or impaired loans for which a sale of the loan is expected as a result of a workout strategy. At December 31, 2015 loans held-for-sale consisted of $485.9 million leveraged finance loans. These loans are carried at the lower of aggregate cost, net of any deferred origination costs or fees, or fair value. As of December 31, 2015 and 2014, loans held-for-sale consisted of the following: December 31, 2015 December 31, 2014 ($ in thousands) Leveraged Finance $ 485,874 $ 202,369 Gross loans held-for-sale 485,874 202,369 Deferred loan fees, net (7,089 ) (1,800 ) Total loans, net $ 478,785 $ 200,569 At December 31, 2015, loans held-for-sale include loans with an aggregate outstanding balance of $485.9 million that were intended to be sold to credit funds managed by the Company. As of February 29, 2016, the Company had sold $37.8 million of the loans intended to be sold to credit funds managed by the Company. The Company sold loans with an outstanding balance totaling $105.3 million for an aggregate gain of $0.5 million to entities other than credit funds during 2015. The Company sold loans with an aggregate outstanding balance of $59.0 million for a gain of $0.2 million to entities other than the credit funds during 2014. The Company sold loans with an aggregate outstanding balance of $32.0 million for a gain of $0.01 million to entities other than the NewStar Credit Opportunities Fund (“NCOF”) during 2013. As of December 31, 2015 and 2014, loans and leases consisted of the following: December 31, 2015 2014 ($ in thousands) Leveraged Finance $ 2,627,314 $ 1,881,277 Business Credit 342,281 286,918 Real Estate 100,732 105,394 Equipment Finance 173,253 96,666 Gross loans and leases 3,243,580 2,370,255 Deferred loan fees, net (51,249 ) (21,376 ) Allowance for loan and lease losses (58,259 ) (42,983 ) Total loans and leases, net $ 3,134,072 $ 2,305,896 The Company provides commercial loans, commercial real estate loans, and leases to customers throughout the United States. The Company’s borrowers may be susceptible to economic slowdowns or recessions and, as a result, may have a lower capacity to make scheduled payments of interest or principal on their borrowings during these periods. Adverse economic conditions also may decrease the estimated value of the collateral, particularly real estate, securing some of the Company’s loans. Although the Company has a diversified loan and lease portfolio, certain events may occur, including, but not limited to, adverse economic conditions and adverse events affecting specific clients, industries or markets, that could adversely affect the ability of borrowers to make timely scheduled principal and interest payments on their loans and leases. The Company internally risk rates loans based on individual credit criteria on at least a quarterly basis. Borrowers provide the Company with financial information on either a quarterly or monthly basis. Loan ratings as well as identification of impaired loans are dynamically updated to reflect changes in borrower condition or profile. A loan is considered to be impaired when it is probable that the Company will be unable to collect all amounts due to it according to the contractual terms of the loan agreement. Impaired loans include all non-accrual loans, loans with partial charge-offs and loans which are troubled debt restructurings (“TDR”). The Company utilizes a number of analytical tools for the purpose of estimating probability of default and loss given default for its four specialized lending groups. The quantitative models employed by the Company in its Leveraged Finance and Equipment Finance businesses utilize Moody’s KMV RiskCalc credit risk model in combination with a proprietary qualitative model, which generates a rating that maps to a probability of default estimate. Real Estate utilizes a proprietary model that has been developed to capture risk characteristics unique to the lending activities in that line of business. The model produces an obligor risk rating which corresponds to a probability of default and also produces a loss given default. In each case, the probability of default and the loss given default are used to calculate an expected loss for those lending groups. Due to the nature of its borrowers and the structure of its loans, Business Credit utilizes a proprietary model that produces a rating that corresponds to an expected loss, without calculating a probability of default and loss given default. For variable interest entities for which the Company is providing transitional capital, a qualitative analysis is used to determine expected loss. In each case, the expected loss is the primary component in a formulaic calculation of general reserves attributable to a given loan. Loans and leases which are rated at or below a specified threshold are typically classified as “Pass”, and loans and leases rated above that threshold are typically classified as “Criticized”, a characterization that may apply to impaired loans, including TDR. As of December 31, 2015, $152.1 million of the Company’s loans were classified as “Criticized”, including $143.6 million of the Company’s impaired loans, and $3.1 billion were classified as “Pass”. As of December 31, 2014, $133.2 million of the Company’s loans were classified as “Criticized”, including $121.8 million of the Company’s impaired loans, and $2.2 billion were classified as “Pass”. When the Company determines a loan is deemed to be impaired, the Company will establish a specific allowance, and the loan will be analyzed and may be placed on non-accrual. If the asset deteriorates further, the specific allowance may increase, and ultimately may result in a loss and charge-off. A TDR that performs in accordance with the terms of the restructuring may improve its risk profile over time. While the concessions in terms of pricing or amortization may not have been reversed and further amended to “market” levels, the financial condition of the Borrower may improve over time to the point where the rating improves from the “Criticized” classification that was appropriate immediately prior to, or at, restructuring. As of December 31, 2015, the Company had impaired loans with an aggregate outstanding balance of $193.2 million. Impaired loans with an aggregate outstanding balance of $183.6 million have been restructured and classified as TDR. As of December 31, 2015, the aggregate carrying value of equity investments in certain of the Company’s borrowers in connection with TDRs totaled $11.4 million. Impaired loans with an aggregate outstanding balance of $111.3 million were also on non-accrual status. For impaired loans on non-accrual status, the Company’s policy is to reverse the accrued interest previously recognized as interest income subsequent to the last cash receipt in the current year. The recognition of interest income on the loan only resumes when factors indicating doubtful collection no longer exist and the non-accrual loan has been brought current. During 2015, the Company charged off $4.0 million of outstanding non-accrual loans. During 2015, the Company placed loans with an aggregate outstanding balance of $38.2 million on non-accrual status and returned loans with an aggregate outstanding balance of $0.9 million to performing status. During 2015, the Company recorded $9.5 million of net specific provisions for impaired loans. At December 31, 2015, the Company had a $26.8 million specific allowance for impaired loans with an aggregate outstanding balance of $121.1 million. At December 31, 2015, additional funding commitments for impaired loans totaled $10.9 million. The Company’s obligation to fulfill the additional funding commitments on impaired loans is generally contingent on the borrower’s compliance with the terms of the credit agreement and the borrowing base availability for asset-based loans, or if the borrower is not in compliance additional funding commitments may be made at the Company’s discretion. As of December 31, 2015, loans to three borrowers totaling approximately $18.6 million were on non-accrual status and were greater than 60 days past due and classified as delinquent by the Company. Included in the $26.8 million specific allowance for impaired loans was $2.8 million related to delinquent loans. During 2012, as part of the resolution of two impaired commercial real estate loans, the Company took control of the underlying commercial real estate properties. The Company recorded a partial charge-off of $2.7 million and classified the commercial real estate properties as other real estate owned. During 2014, the Company sold one of the commercial real estate properties for $9.5 million resulting in a gain on sale of $0.01 million. During 2015, the Company sold the remaining commercial real estate property for $3.0 million resulting in a loss on sale of $0.01 million. A loan is considered impaired when it is probable that a creditor will be unable to collect all amounts due according to the contractual terms of the loan agreement. The measurement of impairment of a loan is based upon (i) the present value of expected future cash flows discounted at the loan’s effective interest rate, (ii) the loan’s observable market price, or (iii) the fair value of the collateral if the loan is collateral dependent, depending on the circumstances and our collection strategy. Impaired loans are identified based on the loan-by-loan risk rating process described above. It is the Company’s policy during the reporting period to record a specific provision for credit losses for all loans for which we have serious doubts as to the ability of the borrowers to comply with the present loan repayment terms. As of December 31, 2014, the Company had impaired loans with an aggregate outstanding balance of $217.2 million. Impaired loans with an aggregate outstanding balance of $175.6 million have been restructured and classified as TDR. As of December 31, 2014, the aggregate carrying value of equity investments in certain of the Company’s borrowers in connection with TDRs totaled $16.4 million. Impaired loans with an aggregate outstanding balance of $87.8 million were also on non-accrual status. During 2014, the Company charged off $18.8 million of outstanding non-accrual loans. During 2014, the Company placed loans with an aggregate outstanding balance of $43.5 million on non-accrual status and returned loans with an aggregate outstanding balance of $1.9 million to performing status. During 2014, the Company recorded $22.2 million of net specific provisions for impaired loans. At December 31, 2014, the Company had a $20.7 million specific allowance for impaired loans with an aggregate outstanding balance of $103.2 million. At December 31, 2014, additional funding commitments for impaired loans totaled $10.9 million. As of December 31, 2014, $43.6 million of loans on non-accrual status were greater than 60 days past due and classified as delinquent by the Company. Included in the $20.7 million specific allowance for impaired loans was $8.7 million related to delinquent loans.

During 2015, 2014 and 2013 the Company recorded recoveries of previously charged-off loans of $0.8 million, $0.1 million and $0.1 million, respectively. The Company’s general policy is to record a specific allowance for an impaired loan to cover the identified impairment of that loan. Any potential charge-off of such loan would typically occur in a subsequent period. The Company may record the initial specific allowance related to an impaired loan in the same period as it records a partial charge-off in certain circumstances such as if the terms of a restructured loan are finalized during that period. When a loan is determined to be uncollectible, the specific allowance is charged off, which reduces the gross investment in the loan. While charge-offs typically have no net impact on the carrying value of net loans and leases, charge-offs lower the level of the allowance for loan and lease losses; and, as a result, reduce the percentage of allowance for loans and leases to total loans and leases, and the percentage of allowance for loan and leases losses to non-performing loans.

In order to mitigate default risk and/or liquidation, assuming that liquidation proceeds are not viewed as a more favorable outcome to the Company and other lenders, the Company will enter into negotiations with the borrower and its shareholders on the terms of a restructuring. When restructuring a loan, the Company undertakes an extensive diligence process which typically includes (i) construction of a financial model that runs through the tenor of the restructuring term, (ii) meetings with management of the borrower, (iii) engagement of third party consultants and (iv) internal analysis. Once a restructuring proposal is developed, it is subject to approval by both the Company’s Underwriting Committee and the Company’s Investment Committee. Loans will only be removed from TDR classification after a period of performance following the refinancing of outstanding obligations on terms which are determined to be “market” in all material respects, or upon full payoff of the loan. The Company may modify loans that are not determined to be a TDR. Where a loan is modified or restructured but loan terms are considered market and no concessions were given on the loan terms, including price, principal amortization or obligation, or other restrictive covenants, a loan will not be classified as a TDR. The Company has made the following types of concessions in the context of a TDR: Group I: · extension of principal repayment term · principal holidays · interest rate adjustments Group II: · partial forgiveness · conversion of debt to equity A summary of the types of concessions that the Company made with respect to TDRs at December 31, 2015 and 2014 is provided below: ($ in thousands) Group I Group II December 31, 2015 $ 183,573 $ 162,986 December 31, 2014 $ 175,589 $ 135,748 Note: A loan may be included in both restructuring groups, but not repeatedly within each group. For 2015 and 2014, the Company had charge-offs totaling $4.0 million and $18.7 million, respectively, related to loans previously classified as a TDR. As of December 31, 2015, the Company had not removed the TDR classification from any loan previously identified as such, but had charged-off, sold and received repayments of outstanding TDRs. The Company measures TDRs similarly to how it measures all loans for impairment. The Company performs a discounted cash flow analysis on cash flow dependent loans and we assess the underlying collateral value less reasonable costs of sale for collateral dependent loans. Management analyzes the projected performance of the borrower to determine if it has the ability to service principal and interest payments based on the terms of the restructuring. Loans will typically not be returned to accrual status until at least six months of contractual payments have been made in a timely manner or the borrower shows significant ability to maintain servicing of the restructured debt. Additionally, at the time of a restructuring and quarterly thereafter, an impairment analysis is undertaken to determine the measurement of specific reserve, if any, on each impaired loan.

The Company employs a variety of internally developed and third-party modeling and estimation tools for measuring credit risk, which are used in developing an allowance for loan and lease losses on outstanding loans and leases. The Company’s allowance framework addresses economic conditions, capital market liquidity and industry circumstances from both a top-down and bottom-up perspective. The Company considers and evaluates a number of factors, including but not limited to, changes in economic conditions, credit availability, industry, loss emergence period, and multiple obligor concentrations in assessing both probabilities of default and loss severities as part of the general component of the allowance for loan and lease losses. On at least a quarterly basis, loans and leases are internally risk-rated based on individual credit criteria, including loan and lease type, loan and lease structures (including balloon and bullet structures common in the Company’s Leveraged Finance and Real Estate cash flow loans), borrower industry, payment capacity, location and quality of collateral if any (including the Company’s Real Estate loans). Borrowers provide the Company with financial information on either a monthly or quarterly basis. Ratings, corresponding assumed default rates and assumed loss severities are dynamically updated to reflect any changes in borrower condition and/or profile. For Leveraged Finance loans and Equipment Finance loans and leases, the data set used to construct probabilities of default in its allowance for loan losses model, Moody’s CRD Private Firm Database, primarily contains middle market loans that share attributes similar to the Company’s loans. The Company also considers the quality of the loan or lease terms and lender protections in determining a loan loss in the event of default. For Business Credit loans, the Company utilizes a proprietary model to risk rate the loans on a monthly basis. This model captures the impact of changes in industry and economic conditions as well as changes in the quality of the borrower’s collateral and financial performance to assign a final risk rating. The Company has also evaluated historical net loss trends by risk rating from a comprehensive industry database covering more than twenty-five years of experience of the majority of the asset based lenders operating in the United States. Based upon the monthly risk rating from the model, the reserve is adjusted to reflect the historical average for expected loss from the industry database. For Real Estate loans, the Company employs two mechanisms to capture the impact of industry and economic conditions. First, a loan’s risk rating, and thereby its assumed default likelihood, can be adjusted to account for overall commercial real estate market conditions. Second, to the extent that economic or industry trends adversely affect a substandard rated borrower’s loan-to-value ratio enough to impact its repayment ability, the Company applies a stress multiplier to the loan’s probability of default. The multiplier is designed to account for default characteristics that are difficult to quantify when market conditions cause commercial real estate prices to decline. For consolidated VIEs to which the Company is providing transitional capital, we utilize a qualitative analysis which considers the business plans related to the entity, including expected hold periods, the terms of the agreements related to the entity, the Company’s historical credit experience, the credit migration of the entity’s loans in determining expected loss, as well as conditions in the capital markets. The Company was providing capital on a transitional basis to the Arlington Fund, prior to the completion of its term debt securitization on June 26, 2014. During the transitional hold period, the expected and actual loss on the Arlington Fund was zero and no allowance was recorded. The Company deconsolidated the Arlington Fund on June 26, 2014. The Company did not recognize any losses on loans on the date of deconsolidation. If the Company determines that changes in its allowance for credit losses methodology are advisable, as a result of changes in the economic environment or otherwise, the revised allowance methodology may result in higher or lower levels of allowance. Moreover, given uncertain market conditions, actual losses under the Company’s current or any revised allowance methodology may differ materially from the Company’s estimate.

The methodology for determining the allowance for unfunded commitments is consistent with the methodology for determining the allowance for loan and lease losses. During 2015, the Company recorded a total provision for credit losses of $18.4 million. The Company increased its allowance for credit losses to $58.7 million as of December 31, 2015 from $43.7 million at December 31, 2014. The Company had $3.4 million of net charge-offs and decreased its general allowance for credit losses by three basis points during 2015, and recorded new specific provisions for credit losses of $9.5 million. The general allowance for credit losses covers probable losses in the Company’s loan and lease portfolio with respect to loans and leases for which no specific impairment has been identified. When a loan is classified as impaired, the loan is evaluated for a specific allowance and a specific provision may be recorded, thereby removing it from consideration under the general component of the allowance analysis. Loans that are deemed to be uncollectible are charged off and deducted from the allowance, and recoveries on loans previously charged off are netted against loans charged off. A specific provision for credit losses is recorded with respect to impaired loans for which it is probable that the Company will be unable to collect all amounts due in accordance with the contractual terms of the loan agreement for which there is impairment recognized. The outstanding balance of impaired loans, which include all of the outstanding balances of the Company’s delinquent loans and its TDRs, as a percentage of “Loans and leases, net” was 6% as of December 31, 2015 and 9% as of December 31, 2014. The Company closely monitors the credit quality of its loans and leases which is partly reflected in its credit metrics such as loan delinquencies, non-accruals and charge-offs. Changes in these credit metrics are largely due to changes in economic conditions and seasoning of the loan and lease portfolio. The Company continually evaluates the appropriateness of its allowance for credit losses methodology. Based on the Company’s evaluation process to determine the level of the allowance for loan and lease losses, management believes the allowance to be adequate as of December 31, 2015 in light of the estimated known and inherent risks identified through its analysis.

The Company did not sell any debt securities during 2015, 2014 or 2013. The following is an analysis of the continuous periods during which the Company has held investment positions which were carried at an unrealized loss as of December 31, 2015 and 2014: December 31, 2015 Less than 12 Months Greater than or Equal to 12 Months Total ($ in thousands) Number of positions 20 3 23 Fair value $ 86,245 $ 7,932 $ 94,177 Amortized cost 95,624 8,631 104,255 Unrealized loss $ (9,379 ) $ (699 ) $ (10,078 ) December 31, 2014 Less than 12 Months Greater than or Equal to 12 Months Total ($ in thousands) Number of positions 8 — 8 Fair value $ 38,740 $ — $ 38,740 Amortized cost 38,943 — 38,943 Unrealized loss $ (203 ) $ — $ (203 ) As a result of the Company’s evaluation of the securities, management concluded that the unrealized losses at December 31, 2015 and 2014 were caused by changes in market prices driven by interest rates and credit spreads. The Company’s evaluation of impairment include quotes from third party pricing services, adjustments to prepayment speeds, delinquency, an analysis of expected cash flows, interest rates, market discount rates, other contract terms, and the timing and level of losses on the loans and leases within the underlying trusts. At December 31, 2015, the Company has determined that it is not more likely than not that it will be required to sell the securities before the Company recovers its amortized cost basis in the security. The Company has also determined that there has not been an adverse change in the cash flows expected to be collected. Based upon the Company’s impairment review process, and the Company’s ability and intent to hold these securities until maturity or a recovery of fair value, the decline in the value of these investments is not considered to be Other Than Temporary. The Company did not record any net OTTI during 2015, 2014 or 2013. Maturities of debt securities classified as available-for-sale were as follows at December 31, 2015 and 2014: December 31, 2015 December 31, 2014 Amortized cost Fair value Amortized cost Fair value ($ in thousands) Available-for-sale: Due one year or less $ — $ — $ — $ — Due after one year through five years — — — — Due after five years through ten years 34,017 30,470 46,870 46,881 Due after ten years through fifteen years 70,238 63,707 — — Total $ 104,255 $ 94,177 $ 46,870 $ 46,881 Actual maturities of debt securities may differ from those presented above since certain obligations amortize and provide the issuer of the individual debt securities the right to call or prepay the obligation prior to the scheduled final stated maturity without penalty.

Subordinated notes On December 4, 2014, the Company completed the initial closing of an investment of long-term capital from funds sponsored by Franklin Square Capital Partners ("Franklin Square") and sub-advised by GSO Capital Partners at which the Franklin Square funds purchased $200.0 million of 10-year subordinated notes (the "Subordinated Notes"), which rank junior to the Company's existing and future senior debt. During the twelve months ended December 31, 2015, the Company drew an additional $75 million of these Subordinated Notes. The Company is required to borrow the remaining $25 million by February 2016. The Subordinated Notes were recorded at par less the initial relative fair value of the warrants issued in connection with the investment on December 4, 2014 and January 23, 2015 which was $60.0 million as of December 31, 2015 and $43.2 million as of December 31, 2014. The debt discount will amortize over the life of the notes and will be recorded as non-cash interest expense as the Subordinated Notes accrete to par value. As of December 31, 2015, unamortized deferred financing fees were $5.5 million. The Subordinated Notes bear interest at 8.25% and include a Payment-in-Kind ("PIK Toggle") feature that allows the Company, at its option, to elect to have interest accrued at a rate of 8.75% added to the principal of the Subordinated Notes instead of paying it in cash. The Subordinated Notes have a ten year term and mature on December 4, 2024. They are callable during the first three years with payment of a make-whole premium. The prepayment premium decreases to 103% and 101% after the third and fourth anniversaries of the closing, respectively. They are callable at par after December 4, 2019. The Subordinated Notes require a mandatory payment at the end of each accrual period, beginning on December 5, 2019. The Company is required to make a cash payment of principal plus accrued interest in an amount required to prevent the Subordinated Notes from being treated as an "Applicable High Yield Discount Obligation" within the meaning of Section 163(i)(1) of the Internal Revenue Code of 1986, as amended. Events of default under the Subordinated Notes include failure to pay interest or principal when due subject to applicable grace periods, material uncured breaches of the terms of the Subordinated Notes, and bankruptcy/insolvency events.

Earnings Per Share [Abstract]
Earnings Per Share	Note 13. Earnings Per Share The Company utilizes the two-class method to calculate earnings per share. The two-class method allocates net income to each class of common stock and participating security. Unvested share-based payment awards granted to certain employees and board members entitle holders to the same rights as outstanding and vested common stock. These securities are considered to be participating securities and are included in the allocation for computing earnings per share under this method. Income is allocated to common shareholders and participating securities under the two-class method based upon the proportion of each to the total weighted average shares available. The computations of basic and diluted earnings per share for the periods ended December 31, 2015, 2014 and 2013 are as follows: December 31, 2015 2014 2013 (In thousands) Numerator: Net income to common shareholders $ 16,890 $ 10,594 $ 24,595 Net income allocated to participating securities - basic and diluted 182 72 625 Net income allocated to common shareholders - basic and diluted $ 16,708 $ 10,522 $ 23,970 Denominator: Denominator for basic earnings per common share 45,631 48,267 48,157 Denominator for diluted earnings per common share: Potentially dilutive securities—options 1,904 3,229 3,671 Potentially dilutive securities—restricted stock — — 762 Potentially dilutive securities—warrants — 79 352 Total weighted average diluted shares 47,535 51,575 52,942 Earnings per common share Basic $ 0.37 $ 0.22 $ 0.51 Diluted 0.35 0.21 0.46 Warrants to purchase common stock totaling 12,000,000 were not included in the computation of earnings per share for the year ended December 31, 2015 due to the fact that the results would be anti-dilutive.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Variable Interest Entity	Note 14. Variable Interest Entity On October 1, 2015, the Company adopted ASU 2015-2, Consolidation – Amendments to the Consolidation Analysis The Company sponsors the formation of various entities that are considered to be VIEs. The majority of these VIEs were formed to issue term debt securitizations. The assets of the VIEs are primarily comprised of senior secured loans and the liabilities are primarily comprised of debt. The Company's determination of whether it is the primary beneficiary of the VIE is based in part on an assessment of whether or not the Company is exposed to the majority of the risks and rewards of the entity. In instances where the Company retains a significant portion of the equity and remains the servicer of the loans, it was determined that the Company has the power to direct the activities that most significantly impact the economic performance of these VIEs. Additionally, the Company determined that the potential fees that we could receive directly or indirectly from these VIEs represent rights to returns that could potentially be significant to the VIEs. As a result, the Company was deemed the primary beneficiary and therefore has consolidated these entities. VIEs that have been consolidated are disclosed in Note 9. The following table sets forth the information with respect to the unconsolidated VIEs for which the Company holds a variable interest in as of December 31, 2015 and December 31, 2014: December 31, 2015 December 31, 2014 ($ in thousands) Unconsolidated VIE assets $ 483,581 $ 400,000 Unconsolidated VIE liabilities 362,383 368,750 Equity interest included on the Consolidated Balance Sheet 23,910 — Maximum risk of loss (1) 24,327 1,047 (1) Includes equity investment the Company has made, or is required to make, and any earned but uncollected management and incentive fees. The Company does not record performance and incentive allocations until the respective measurement period has ended. The Company’s involvement with term debt securitizations and sponsored funds that are VIEs and unconsolidated by the Company is generally limited to that of an investment manager and its investment in the unconsolidated VIE. The Company is not the primary beneficiary of these unconsolidated VIEs. The Company’s investment in any unconsolidated VIE generally represent an insignificant equity interest. The Company’s exposure to the risk in these entities is generally limited to any capital contributions it has made or is required to make and any earned but uncollected management fees. Unconsolidated VIEs In January 2015, NewStar closed a new managed credit fund, NewStar Clarendon Fund CLO LLC (the “Clarendon Fund”), a $400.0 million term debt securitization. The Clarendon Fund is the third credit fund established by the Company to co-invest in directly originated middle market commercial loans. To comply with European Union (“EU”) risk retention rules, the Company holds 5% of each class of notes in the securitization (vertical strip), totaling $20.4 million. The Clarendon Fund employs an independent investment professional who is responsible for investment decision making on behalf of the fund. The Company has determined that it is not the primary beneficiary of the Clarendon Fund and will not consolidate the Clarendon Fund’s operating results or statements of financial position; however, has determined that we have a variable interest in the Clarendon Fund as we hold notes of the securitization. In October 2015, NewStar acquired FOC Partners. FOC Partners acts as an investment manager for six collateralized loan obligations and two sponsored funds and provides discretionary services to a series of separately managed accounts. NewStar has determined that it is not the primary beneficiary of any of acquired CLOs, sponsored funds or separately managed accounts; however has determined that we have a variable interest in the Secured Value sponsored fund as we hold approximately one percent of the interest of the fund. Former Unconsolidated VIEs In April 2013, the Company formed a new managed credit fund, NewStar Arlington Fund LLC (“Arlington Fund”) in partnership with an institutional investor to co-invest in middle market commercial loans originated by the Company’s Leveraged Finance group. As the managing member of the Arlington Fund, the Company retained full discretion over Arlington Fund’s investment decisions, subject to usual and customary limitations, and earned management fees as compensation for its services. For 2014 and 2013, the management fee was $0.5 million for each year. On April 4, 2013, Arlington Fund entered into an agreement establishing $147.0 million of Class A variable funding notes (the “Class A Notes”) and $28.0 million of Class B variable funding notes (the “Class B Notes”) to partially fund eligible middle market loan origination for Arlington Fund. Wells Fargo Bank, National Association funded the Class A Notes as the initial Class A lender and the Company funded the Class B Notes as the initial Class B lender. For 2014 and 2013, interest expense on the Class B Notes totaled $0.7 million for each year. For 2014 and 2013, the Fund distributed excess cash to its institutional investor totaling $0.7 million and $0.6 million, respectively. From inception, the Company was deemed to be the primary beneficiary of Arlington Fund and, therefore, consolidated the financial results of Arlington Fund with the Company’s results of operations and statements of financial position since April 2013. On June 26, 2014, the NewStar Arlington Senior Loan Program LLC (the “Arlington Program”) completed a $409.4 million term debt securitization comprised of all of the Arlington Fund’s loans as well as a portion of the Company’s loans classified as held-for-sale. A portion of the proceeds from this term debt securitization were used to repay all advances under the Class A Notes and the Class B Notes. Following repayment, the Class A Notes and the Class B Notes were redeemed. As a result, the amortization of $1.1 million of deferred financing fees was accelerated and recognized during the three months ended June 30, 2014. The Company’s membership interests in Arlington Fund were also redeemed and new membership interests in the Arlington Program were issued to its equity investors. The Company did not recognize a gain or a loss on the redemption of its membership interests in the Arlington Fund. The Company acts as collateral manager for the Arlington Program. As a result of the repayment of the Company’s advances as the Class B lender under the warehouse facility and the redemption of its membership interests in the Arlington Fund, the Company has no ownership or financial interests in the Arlington Fund or its successors except to the extent that it receives management fees as collateral manager of the Arlington Program. Additionally, the Arlington Program employs an independent investment professional who is responsible for investment decision making on behalf of the program. As a result, the Company deconsolidated the Arlington Fund from its statements of financial position beginning on June 26, 2014. The Company determined that it is not the primary beneficiary of the Arlington Program and will not consolidate the Arlington Program’s operating results or statements of financial position as of that date. Although the Company consolidated all of the assets and liabilities of Arlington Fund, during the period from April 4, 2013 through June 26, 2014, its maximum exposure to loss was limited to its investments in membership interests in Arlington Fund, its Class B Note receivable, as well as the management fee receivable from Arlington Fund. These items defined the Company’s economic relationship with Arlington Fund but were eliminated upon consolidation. The Company managed the assets of Arlington Fund solely for the benefit of its lenders and investors. If the Company were to have liquidated, the assets of Arlington Fund would not have been available to the Company's general creditors. Conversely, the investors in the debt of Arlington Fund had no recourse to the Company's general assets. Therefore, the Company did not consider this debt its obligation. During the period from April 4, 2013 through June 26, 2014 when the Company consolidated the Arlington Fund as a VIE, the membership interests representing equity ownership of Arlington Fund were characterized as debt in the Company’s consolidated statement of financial position. The Company applied an imputed interest rate to that debt and recorded the resulting interest expense in its consolidated statement of operations. In the consolidation, the Company eliminated the economic results of its related portion of the membership interests and the applied interest expense from its results of operations and statements of financial position. As a result of the re-evaluation of the Company’s VIEs, the Arlington Program is no longer considered a VIE.

Financial Instruments with Off-Balance Sheet Risk	Note 15. Financial Instruments with Off-Balance Sheet Risk The Company is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its borrowers. These financial instruments include unfunded commitments and standby letters of credit. The instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheet. The contract or notional amounts of those instruments reflect the extent of involvement we have in particular classes of financial instruments. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Unused lines of credit are commitments to lend to a borrower if certain conditions have been met. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Because certain commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each borrower’s creditworthiness on a case-by-case basis. The amount of collateral required is based on factors that include management’s credit evaluation of the borrower and the borrower’s compliance with financial covenants. Due to their fluctuating nature, the Company cannot know with certainty the aggregate amounts that will be required to fund its unfunded commitments. The aggregate amount of these unfunded commitments currently exceeds the Company’s available funds and will likely continue to exceed its available funds in the future. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending credit to our borrowers. Standby letters of credit are conditional commitments issued by us to guarantee the performance by a borrower to a third party. Financial instruments with off-balance sheet risk are summarized as follows: December 31, 2015 2014 ($ in thousands) Unused lines of credit $ 601,805 $ 317,583 Standby letters of credit 8,696 7,911

Total Return Swap	Note 16. Total Return Swap On December 4, 2014, NewStar TRS I LLC, a newly-formed subsidiary of the Company, entered into a total return swap of senior secured floating rate loans with Citibank, N.A. The initial maximum market value (determined at the time such loan becomes subject to the TRS) of the portfolio of loans subject to the TRS was $75.0 million. On March 2, 2015, we entered into an amendment to the TRS that increased the maximum value to $150.0 million, and on July 14, 2015, we entered into an additional amendment to the TRS that increased the maximum value to $175.0 million. The underlying loan portfolio of the TRS is typically large, liquid broadly syndicated loans. We act as the manager of the TRS and select the specific loans to be subject to the TRS. The TRS does not qualify for hedge accounting treatment as it does not offset the risks of another investment position. A total return swap is a contract in which one party agrees to make periodic payments to another party based on the change in the market value of the assets underlying the TRS, in return for periodic payments based on a fixed or variable interest rate. The TRS effectively added leverage to the Company's portfolio by providing economic benefits of the loans subject to the TRS, despite the fact that such loans will not be directly owned the Company, in return for an interest-type payment to Citibank. The Company's obligations under the TRS are non-recourse to it, and its exposure is limited to the value of the cash collateral which may fluctuate from time to time depending on the market value of the underlying loans. The Company is required to cash collateralize a specified percentage of each loan included under the TRS in accordance with margin requirements. As of December 31, 2015 and December 31, 2014, the Company had cash collateral on deposit with Citibank of $56.5 million and $39.0 million, respectively. The Company pays interest to Citibank for each loan at a rate equal to one-month LIBOR plus 1.60% per annum. Upon the termination or repayment of any loan under the TRS Agreement, the Company would deduct the appreciation of such loan's value from any interest owed to Citibank or pay the depreciation amount to Citibank in addition to remaining interest payments. Citibank may terminate the TRS on or after March 4, 2016, and we can terminate the TRS at any time upon providing 10 days notice subject to a termination fee if terminated prior to March 4, 2016. At December 31, 2015, the receivable and realized loss on the total return swap on the consolidated balance sheet and consolidated statements of operations consisted of the following: Net Receivable Net Realized Gains/(Losses) ($ in thousands) Interest income from TRS portfolio $ — $ 8,667 TRS interest expense — 2,652 Realized loss on TRS (5,816 ) (4,822 ) TRS receivable 1,377 — At December 31, 2014, the receivable and realized loss on the total return swap on the consolidated balance sheet and consolidated statements of operations consisted of the following: Net Receivable Net Realized Gains/(Losses) ($ in thousands) Interest income from TRS portfolio $ — $ 209 TRS interest expense — 86 Realized loss on TRS (863 ) (863 ) TRS receivable 123 — The loans underlying the TRS are valued, primarily on the indicative bid prices provided by an independent third-party pricing service. The fair value of the TRS is reflected as an unrealized gain or loss on the total return swap on the consolidated balance sheet, within other assets or liabilities. The change in value of the TRS is reflected in the consolidated statements of operations as net unrealized appreciation (depreciation) on the total return swap within other (loss) income. As of December 31, 2015 and 2014, the fair value of the TRS was $155.6 million and $109.2 million, respectively.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company’s management considered all available evidence, both positive and negative, in determining the realizability of deferred tax assets at December 31, 2015. Management considered carryback availability, the scheduled reversals of deferred tax liabilities, projected future taxable income during the reversal periods, and tax planning strategies in making this assessment. Management also considered our recent history of taxable income, trends in our earnings, positive financial ratios, and the impact of the downturn in the current economic environment (including the impact of credit on allowance and provision for loan losses) on the Company. Based upon its assessment, management believes that a valuation allowance was not necessary as of December 31, 2015. The Company files U.S. federal and various state income tax returns. As of December 31, 2015, the Company is subject to examination by the Internal Revenue Service and most state tax authorities for tax years after December 31, 2011. A few states remain subject to examination for the year ended December 31, 2010.

Fair Value Disclosures [Abstract]
Fair Value	Note 18. Fair Value ASC 820, Fair Value Measurements and disclosures, · Level 1—inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. · 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 financial instrument. · Level 3—inputs to the valuation methodology are unobservable and significant to the fair value measurement. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following is a description of the valuation methodologies used for instruments measured at fair value, including the general classification of such instruments pursuant to the valuation hierarchy. Items Recorded at Fair Value on a Recurring Basis Investments in debt securities, available-for-sale Investments in debt securities available-for-sale are recorded at fair value on a recurring basis. The fair value measurement of investments in debt securities is based on third party pricing services or by using internally developed financial models. For securities in less liquid markets where there is limited activity and little transparency around broker quotes used to value such securities, the Company classifies securities valued using broker quotes as Level 3. If quoted prices are not available, then fair value is estimated by using internally developed financial models. These securities are not actively traded and require a private sale, and the valuation involves application of significant management judgment. Inputs into the model-based valuations can include changes in market indexes, selling prices of similar securities, management’s assumptions related to the credit rating of the security, prepayment assumptions and other factors such as credit loss assumptions and management’s assessment of the current market conditions. Such securities are classified as Level 3, as the valuation models are based on significant inputs that are unobservable in the market. Total return swap The fair value of the total return swap is based on third party pricing services who collect prices through a variety of methods including dealer runs, indicative sheets and online posts. The Company records the total return swap as Level 2. Items Measured at Fair Value on a Nonrecurring Basis Collateral dependent impaired loans Collateral dependent loans that are deemed to be impaired are valued based upon the fair value of the underlying collateral. For collateral dependent loans for which repayment is dependent on the sale of the collateral, management adjusts the fair value for estimated costs to sell. For collateral dependent loans for which repayment is dependent on the operation of the collateral, management may also adjust values to reflect estimated market value declines or apply other discounts to appraised values. Collateral dependent impaired loans are categorized as Level 3. Loans held-for-sale Loans held-for-sale are not recorded at fair value on a recurring basis, they are carried at either the lower of cost or fair value. When fair value is determined to be the carrying value, the values are based on quoted prices, where available, or are determined by discounting estimated cash flows using model-based valuation techniques. Inputs into the model-based valuations can include changes in market indexes, selling prices of similar loans, management’s assumption related to credit rating of the loan, prepayment assumptions and other factors, such as credit loss assumptions. Where quoted market prices are obtained through dealer quotes, broker indicative prices or online posts, loans held-for-sale are classified as Level 2. Loans held-for-sale are classified as Level 3 in instances where valuation models are based on significant inputs that are unobservable in the market. Other real estate owned or repossessed assets The Company does not record other real estate owned or repossessed assets at fair value on a recurring basis. The fair value is estimated using one of several methods, including collateral value, market value of similar properties, liquidation value and discounted cash flows. M anagement may adjust the fair value for estimated costs to sell or adjust values to reflect estimated market value declines or apply other discounts to values. The following table presents recorded amounts of assets and liabilities measured at fair value on a recurring and nonrecurring basis as of December 31, 2015 and placement in the fair value hierarchy (as described above).

When a determination is made to classify a financial instrument as Level 3, the determination is based upon the significance of the unobservable parameters to the overall fair value measurement. However, Level 3 financial instruments typically include, in addition to the unobservable or Level 3 components, observable components (that is, components that are actively quoted and can be validated to external sources); accordingly, the gains and losses in the table below include changes in fair value due in part to observable factors that are part of the valuation methodology. The Company did not transfer any financial instruments in or out of Level 1, 2, or 3 during 2015 and 2014.

Investments in debt securities: The fair values of debt securities are based on quoted market prices, when available, at the reporting date for those or similar investments. When no market data is available, we estimate fair value using various valuation tools including cash flow models that utilize financial statements and business plans, as well as qualitative factors. Loans held-for-sale, net: The fair values are based on quoted prices, where available, or are determined by discounting estimated cash flows using model-based valuation techniques. Inputs into the model-based valuations can include changes in market indexes, selling prices of similar loans, management’s assumption related to credit rating of the loan, prepayment assumptions and other factors, such as credit loss assumptions. Loans and leases, net: The fair value was determined as the present value of expected future cash flows discounted at current market interest rates offered by similar lending institutions for loans with similar terms to companies with comparable credit risk. This method of estimating fair value is based on significant unobservable inputs and should approximate an exit price fair value. The amount included in the above table excludes impaired collateral-dependent commercial real estate loans. Credit facilities: Due to the adjustable rate nature of the borrowings, the fair values of the credit facilities are estimated to approximate their carrying values. Rates currently are comparable to those offered to the Company for similar debt instruments of comparable maturities by the Company’s lenders. Term debt securitizations: The fair value was determined by applying prevailing term debt securitization market interest rates to the Company’s current term debt securitization structure. Repurchase agreements: The fair value was determined by applying prevailing repurchase agreement market interest rates to the Company’s current repurchase agreement structure. Senior notes: The fair value was based on available quoted market prices. Subordinated notes: The fair value was estimated as the present value of expected future cash flows discounted at market interest rates on similar debt instruments, issued by companies with comparable credit ratings. Corporate debt: The fair value was determined as the present value of future cash flows discounted at market interest rates on similar debt instruments. Other assets/other liabilities : Comprised of non-public investments and the total return swap. The non-public investments are carried at $14.3 million and $18.3 million, as of December 31, 2015 and 2014, respectively. These investments are in the form of warrants and are obtained as part of the loan origination process. Warrants which contain a net exercise provision are required to be accounted for as derivatives and recorded at fair value. The fair value of the derivative warrant portfolio is reviewed quarterly and adjustments to the fair value are recorded in current earnings. Fair value is determined using internally developed valuation models. Where sufficient data exists, a market approach method is utilized to estimate the current value of the underlying company. The estimated fair value of the underlying securities for warrants requiring valuation at fair value were adjusted for discounts related to lack of liquidity. The Company classifies warrants accounted for as derivatives as Level 3. The total return swap is based on third party pricing services who collect prices through a variety of methods including dealer runs, indicative sheets and online posts. The Company classifies the total return swap as Level 2.

Credit Facility Amendments On January 26, 2016 and February 11, 2016, we entered into amendments to our credit facility with Wells Fargo Bank, National Association to fund leveraged finance loans. The amendment increased the commitment amount under the credit facility from $475.0 million to $565.0 million. Term Debt Securitization On March 2, 2016, we completed a $348.0 million term debt securitization. The notes offered in the collateralized loan obligation (the “Notes”) were issued by NewStar Commercial Loan Funding 2016-1 LLC, a subsidiary of the Company (“NCLF”), and are backed by a diversified portfolio of commercial loans originated and serviced by the Company. We offered approximately $255.8 million of the asset-backed Notes, representing approximately 74% of the value of the collateral pool. The Company retained the Class D Notes, Class E Notes and all of the equity which totaled approximately $92.2 million, representing approximately 26% of the value of the collateral pool. Excluding the fixed rate A-2 Notes, the blended pricing of the variable rate Notes was LIBOR plus 2.78% at closing. The reinvestment period is expected to end on February 25, 2020 and the Notes are expected to mature on February 25, 2028. Stock Repurchase Program On October 7, 2015, our Board of Directors authorized the repurchase of up to $5.0 million of the Company’s common stock from time to time on the open market or in privately negotiated transactions. As of December 31, 2015, we had repurchased 7,167 shares of our common stock under this program at a weighted average price per share of $8.84. On February 10, 2016, our Board of Directors authorized an increase to this stock repurchase program, of which approximately $4.9 million remained available for repurchase, to authorize the repurchase of up to an aggregate of $30.0 million of the Company’s common stock (inclusive of the amount remaining under the existing program). The timing and amount of any shares purchased under the repurchase program will be determined by our management based on its evaluation of market conditions and other factors. The repurchase program, as amended, will expire on December 31, 2016 unless extended by the Board and may be suspended or discontinued at any time without notice.

Summary of Significant Accoun31

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Consolidation	Consolidation The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries (collectively, “NewStar”) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). All significant intercompany transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Estimates most susceptible to change in the near-term are the Company’s estimates of their allowance for credit losses, impairment of loans, recorded amounts of deferred income taxes, and impairment of goodwill and identifiable intangible assets.
Prior Period Reclassification	Prior Period Reclassifications Certain prior period disclosure amounts have been reclassified to conform to current period presentation.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include all demand deposits held in banks and certain highly liquid instruments with original maturities of 90 days or less.
Investments in Debt Securities	Investments in Debt Securities Management determines the classification of securities at the time of purchase. If management has the intent and the Company has the ability at the time of purchase to hold securities until maturity, they are classified as held-to-maturity. Investment securities held-to-maturity are stated at amortized cost. Securities to be held for indefinite periods of time, but not necessarily to be held-to-maturity or on a long-term basis, are classified as available-for-sale and carried at fair value with unrealized gains or losses reported in other comprehensive income, net of applicable income taxes. The fair value of debt securities are based on quoted market prices, when available, at the reporting date for those or similar investments. When no market is available, the Company estimates fair value using various valuation tools, including cash flow analyses that utilize financial statements, business plans, as well as qualitative factors. The carrying values of all securities are adjusted for amortization of premiums and accretion of discounts over the shorter of the period to call or maturity of the related security using a method that approximates the interest method. Realized gains or losses on the sale of securities, if any, are determined using the amortized cost of the specific securities sold. Management evaluates securities for other-than-temporary impairment (“OTTI") on a periodic basis. Factors considered in determining whether an impairment is OTTI include: (1) the length of time and the extent to which the fair value has been less than amortized cost, (2) projected future cash flows, (3) the financial condition and near-term prospects of the issuers and (4) the intent and ability of the Company to hold the investment for a period of time sufficient to allow for any anticipated recovery in fair value. The Company records an OTTI loss in an amount equal to the entire difference between the fair value and amortized cost if (1) the Company intends to sell an impaired investment security, (2) it is more likely than not that the Company will be required to sell the investment security before its amortized costs or (3) for debt securities, the present value of expected future cash flows is not sufficient to recover the entire amortized cost basis. If an investment security is determined to be OTTI but the Company does not intend to sell the investment security, only the credit portion of the estimated loss is recognized in earnings, with the non-credit portion of the loss recognized in other comprehensive income.
Loans Held-for-Sale	Loans Held-for-Sale Loans classified as held-for-sale consist of loans originated by the Company, intended to be sold or syndicated to third parties (including credit funds managed by the Company) or impaired loans for which a sale of the loan is expected as a result of a workout strategy. These loans are carried at the lower of aggregate cost, net of any deferred origination costs or fees, or fair value.
Loans	Loans Loans are stated at the principal amount outstanding. Interest income is recorded on the accrual basis in accordance with the terms of the respective loan. Loans on which the accrual of interest has been discontinued are designated as nonaccrual loans. The accrual of interest on loans is typically discontinued when principal or interest payments are past due 90 days or when, in the opinion of management, it is probable it will be unable to collect contractual principal and interest in the normal course of business. When loans are placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income. Income on nonaccrual loans is subsequently recognized only to the extent that cash is received and the loan’s principal balance is deemed collectible. Nonrefundable loan fees and related direct costs associated with the origination of loans are deferred and included in loans, net in the consolidated balance sheet. The net deferred fees or costs are recognized as an adjustment to interest income over the contractual life of the loans using a method which approximates the interest method or taken into income when the related loans are paid off or sold. The Company accretes any discount from purchased loans into loan fee income as a yield adjustment over the contractual life of the loan. The amortization of loan fees is discontinued on non-accrual loans.
Provision and Allowance for Credit Losses	Provision and Allowance for Credit Losses Our general allowance for credit losses covers probable losses in our loan and lease portfolio with respect to loans and leases that are not impaired and for which no specific impairment has been identified. A specific provision for credit losses is recorded with respect to loans for which it is probable that we will be unable to collect all amounts due in accordance with the contractual terms of the loan agreement for which there is impairment recognized. The Company employs a variety of internally developed and third-party modeling and estimation tools for measuring credit risk, which are used in developing an allowance for loan and lease losses on outstanding loans and leases. The Company’s allowance framework addresses economic conditions, capital market liquidity and industry circumstances from both a top-down and bottom-up perspective. The Company considers and evaluates a number of factors, including but not limited to, changes in economic conditions, credit availability, industry, loss emergence period, and multiple obligor concentrations in assessing both probabilities of default and loss severities as part of the general component of the allowance for loan and lease losses. On at least a quarterly basis, loans and leases are internally risk-rated based on individual credit criteria, including loan and lease type, loan and lease structures (including balloon and bullet structures common in the Company’s Leveraged Finance and Real Estate loans), borrower industry, payment capacity, location and quality of collateral if any (including the Company’s Real Estate loans). Borrowers provide the Company with financial information on either a monthly or quarterly basis. Ratings, corresponding assumed default rates and assumed loss severities are dynamically updated to reflect any changes in borrower condition or profile. For Leveraged Finance loans and Equipment Finance products, the data set used to construct probabilities of default in its allowance for loan losses model, Moody’s CRD Private Firm Database, primarily contains middle market loans that share attributes similar to the Company’s loans. The Company also considers the quality of the loan or lease terms and lender protections in determining a loan loss in the event of default. For Business Credit loans, the Company utilizes a proprietary model to risk rate the loans on a monthly basis. This model captures the impact of changes in industry and economic conditions as well as changes in the quality of the borrower’s collateral and financial performance to assign a final risk rating. The Company has also evaluated historical loss trends by risk rating from a comprehensive industry database covering more than twenty-five years of experience of the majority of the asset based lenders operating in the United States. Based upon the monthly risk rating from the model, the reserve is adjusted to reflect the historical average for expected loss from the industry database. For Real Estate loans, the Company employs two mechanisms to capture the impact of industry and economic conditions. First, a loan’s risk rating, and thereby its assumed default likelihood, can be adjusted to account for overall commercial real estate market conditions. Second, to the extent that economic or industry trends adversely affect a substandard rated borrower’s loan-to-value ratio enough to impact its repayment ability, the Company applies a stress multiplier to the loan’s probability of default. The multiplier is designed to account for default characteristics that are difficult to quantify when market conditions cause commercial real estate prices to decline. For consolidated variable interest entities to which the Company is providing transitional capital, we utilize a qualitative analysis which considers the business plans related to the entity, including expected hold periods, the terms of the agreements related to the entity, the Company’s historical credit experience, the credit migration of the entity’s loans in determining expected loss, as well as conditions in the capital markets. The Company provided capital on a transitional basis to the Arlington Fund. The Company deconsolidated the Arlington Fund on June 26, 2014. The Company did not recognize any losses on loans on the date of deconsolidation. The Company periodically reviews its allowance for credit loss methodology to assess any necessary adjustments based upon changing economic and capital market conditions. If the Company determines that changes in its allowance for credit losses methodology are advisable, as a result of changes in the economic environment or otherwise, the revised allowance methodology may result in higher or lower levels of allowance. In 2015, the Company enhanced its approach for determining the expected exposure at default to more precisely reflect loan and lease exposures at December 31, 2015. Given uncertain market conditions, actual losses under the Company’s current or any revised allowance methodology may differ materially from the Company’s estimate. Additionally, when determining the amount of the general allowance, the Company supplements the base amount with an environmental reserve amount which is governed by a score card system comprised of seven risk factors. The risk factors are designed based on those outlined in the Comptrollers of the Currency’s Allowance for Loan and Lease Losses Handbook. In 2015, the scoring system of the environmental reserve risk factors was recalibrated to align with the enhancement made to the approach for determining the exposure at default. The Company also performs a ratio analysis of comparable money center banks, regional banks and finance companies. While the Company does not rely on this peer group comparison to set the level of allowance for credit losses, it does assist management in identifying market trends and serves as an overall reasonableness check on the allowance for credit losses computation. A loan is considered impaired when it is probable that a creditor will be unable to collect all amounts due according to the contractual terms of the loan agreement. Impairment of a loan is based upon (i) the present value of expected future cash flows discounted at the loan’s effective interest rate, (ii) the loan’s observable market price, or (iii) the fair value of the collateral if the loan is collateral dependent, depending on the circumstances and our collection strategy. Impaired loans are identified based on the loan-by-loan risk rating process described above. Impaired loans include all non-accrual loans, loans with partial charge-offs and loans which are Troubled Debt Restructurings (see Note 4). It is the Company’s policy during the reporting period to record a specific provision for credit losses to cover the identified impairment on a loan. Impaired loans at December 31, 2015 were in Leveraged Finance, Equipment Finance and Real Estate over a range of industries impacted by the then current economic environment including the following: Media and Communications, Industrial, Commercial Real Estate, Other Business Services, Consumer/Retail, and Building Materials. For impaired Leveraged Finance and Equipment Finance loans, the Company measured impairment based on expected cash flows utilizing relevant information provided by the borrower and consideration of other market conditions or specific factors impacting recoverability. Such amounts are discounted based on original loan terms. For impaired Real Estate loans, the Company determined that the loans were collateral dependent and measured impairment based on the fair value of the related collateral utilizing recent appraisals from third-party appraisers, as well as internal estimates of collateral market value. Loans deemed to be uncollectible are charged off and the allowance is reduced by the charged off balance of the loan. The provision for credit losses and recoveries on loans previously charged off are added to the allowance.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs represent fees and other direct incremental costs incurred in connection with borrowings and term debt securitizations. These amounts are amortized using the straight-line method into earnings as interest expense ratably over the contractual term of the facility or the estimated life of the term debt securitization.
Valuation of Debt and Equity Linked Instruments	Valuation of debt and equity linked instruments We account for the subordinated notes and associated warrants issued to Franklin Square as debt and equity-linked instruments. The warrants are freestanding, indexed to the Company's common stock and are classified as equity. They were initially recorded at relative fair value, with no subsequent re-measurement. The allocation of the proceeds from the issuance of debt and warrants to Franklin Square was determined using the relative fair value method. The allocation of proceeds to the warrants created a debt discount to the subordinated debt and will be amortized over the life of the subordinated notes. The subordinated debt is presented net of the debt discount.
Property and Equipment	Property and Equipment Property and equipment are carried at cost and depreciated or amortized on a straight-line basis over the following useful lives: Leasehold improvements Shorter of estimated life or remaining lease term Furniture, fixtures and equipment 3-5 years
Goodwill and Identified Intangible Assets	Goodwill and Identified Intangible Assets Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Goodwill is not subject to amortization but tested for impairment at least annually utilizing a qualitative or quantitative approach or more frequently if events or circumstances occur that indicate that impairment may have occurred. As part of this evaluation, the Company makes a qualitative assessment of whether it is more likely than not that the fair value of an acquired asset is greater than its carrying amount. If the Company qualitatively concludes that it is more likely than not that the fair value of an acquired asset is greater than its carrying amount, no further testing is necessary. If, however, the Company qualitatively concludes that it is more likely than not that the fair value of an acquired asset is less than its carrying value, the Company performs a two-step quantitative impairment test to determine whether the asset is impaired. If impairment is deemed to have occurred, then an impairment loss would be recognized for the amount by which the carrying amount exceeds its fair value. Identified intangible assets are assets resulting from acquisitions that are being amortized over their estimated useful lives. The recoverability of identified intangible assets is evaluated for impairment at least annually. If impairment is deemed to have occurred, then an impairment loss would be recognized for the amount by which the carrying amount exceeds fair value.
Earnings Per Share (“EPS”)	Earnings Per Share (“EPS”) The Company utilizes the two-class method to calculate earnings per share, which requires that unvested share-based awards be treated as participating securities in the computation of EPS. Under the two-class method, earnings are allocated to common shareholders and participating securities based upon the proportion of each to the total weighted average shares available. Basic earnings per common share is computed by dividing net earnings allocated to common shareholders by the weighted-average number of common shares outstanding. Diluted earnings reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in our earnings.
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability is not adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities. It is not a forced transaction. Market participants are buyers and sellers in the principal market that are independent, knowledgeable, able to transact and willing to transact. ASC 820, Fair Value Measurement
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company classifies all interest and penalties on recognized tax benefits as a part of income tax expense. As of December 31, 2015 and 2014, the Company did not have any significant accrued interest, penalties or uncertain tax positions.
Fee Income Recognition	Fee Income Recognition Origination fees and costs are deferred and amortized as yield adjustments over the contractual life of the loans and investments. In connection with the prepayment of a loan or other debt product, any remaining unamortized net deferred fees for that loan are accelerated and, depending on the terms of the loan, there may be an additional fee charged based upon the prepayment and recognized in the period of the prepayment. Syndication and structuring fees are recognized in the period the service is completed and funds received as fee income.
Asset Management Income	Asset Management Income NewStar Financial, Inc. earns asset management income for investment management services performed for managed credit funds related funds. NewStar accrues this income when earned, on a monthly basis, and classifies it as asset management income in the consolidated statements of operations.
Stock Based Compensation	Stock Based Compensation The Company follows ASC 718, Share-Based Payment For awards granted, modified, repurchased or cancelled after January 1, 2006, the Company estimates the fair value of stock-based awards using the Black-Scholes valuation model, which requires the input of subjective assumptions, including expected term and expected price volatility. Changes in these assumptions can materially affect the calculated fair value of stock-based compensation and the related expense to be recognized. Further, for awards that contain performance measures and conditions, the Company makes an assessment, based on management’s judgment, of the probability of these conditions being satisfied, which affects the timing and the amount of expense to be recognized. If the Company’s judgment as to whether these conditions are probable of occurrence are not appropriate, the financial statements could be materially affected.
Gain (loss) on Sale of Loans	Gain (loss) on sale of loans All loans sold to date have been sold without recourse. When loans are sold, a gain or loss is recognized to the extent that the sales proceeds plus unamortized fees and costs exceed or are less than the carrying value of the loans. Gains and losses are determined using the specific identification method.
Equity and Cost Method Investments	Equity and Cost Method Investments The Company may acquire a portion of the equity in borrowers. In cases where the Company has the ability to exercise significant influence over the borrower, it accounts for its equity interest under the equity method of accounting. Under the equity method of accounting, the Company recognizes its proportional share of the borrower’s GAAP net income in its results of operations. In cases where the equity of the underlying company has no value, and the borrower incurs losses, the Company will apply its proportional share of the GAAP loss against the principal of the outstanding loan to the borrower. In circumstances where we do not have substantial influence over the company, we account for the equity interest under the cost method of accounting. The equity interest is recorded on our books at its historical cost. The Company evaluates its equity and cost method investments for impairment by assessing whether the fair value of the equity interest has declined below its carrying value for a period we consider other-than-temporary. If it determines that a decline in fair value below our carrying value is other-than-temporary, an impairment is recognized to reduce the carrying value of the investment to its fair value.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities The Company accounts for derivatives and hedging activities on the balance sheet in either other assets or other liabilities at their respective fair values. On the date a derivative contract is entered into, the Company designates the derivative as either (1) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge) or as (2) a derivative trading instrument. For all hedging relationships the Company formally documents the hedging relationship and its risk-management objective and strategy for undertaking the hedge, the hedging instrument, the item, the nature of the risk being hedged, how the hedging instrument’s effectiveness in offsetting the hedged risk will be assessed, and a description of the method of measuring ineffectiveness. This process includes linking all derivatives that are designated as hedges to specific assets and liabilities on the balance sheet or to forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. Changes in the fair value of a derivative that is highly effective and that is designated and qualifies as a cash-flow hedge are recorded in other comprehensive income to the extent that the derivative is effective as a hedge, until earnings are affected by the variability in cash flows of the designated hedged item. The ineffective portion of the change in fair value of a derivative instrument that qualifies as a cash-flow hedge is reported in earnings. The Company discontinues hedge accounting prospectively when it is determined that the derivative is no longer effective in offsetting changes in the cash flows of the hedged item, the derivative expires or is sold, terminated, or exercised, the derivative is de-designated as a hedging instrument because it is unlikely that a forecasted transaction will occur, or management determines that designation of the derivative as a hedging instrument is no longer appropriate. In all situations in which hedge accounting is discontinued or was never applied, the Company continues to carry the derivative at its fair value on the balance sheet and recognizes any subsequent changes in its fair value in earnings. When hedge accounting is discontinued because it is probable that a forecasted transaction will not occur by the date (or within the time period) originally specified or within an additional two-month period of time thereafter, the Company recognizes immediately in earnings, gains and losses that were accumulated in other comprehensive income. Gains and losses on derivatives not designated as hedges, including any cash payments made or received, are reported as gain (loss) on derivatives in the accompanying consolidated statements of operations.
Total Return Swap	Total Return Swap The Company is party to a total return swap (“TRS”). A TRS is a contract in which one party agrees to make periodic payments to another party based on the change in the market value of the assets underlying the TRS, in return for periodic payments based on a fixed or variable interest rate. The TRS effectively added leverage to our portfolio by providing investment exposure to underlying loans without owning or taking physical custody, in return for an interest-type payment to Citi. The TRS is recorded at fair value as an asset or liability with changes in fair value recorded as unrealized appreciation or depreciation. Realized gains or losses are recognized at the termination of the contract.
Comprehensive Income (Loss), net of tax	Comprehensive Income (Loss), net of tax The Company records the change in fair value of cash flow hedge derivatives and unrealized gains and losses on available-for-sale securities in comprehensive income. Gains and losses on available-for-sale securities are reclassified to net income as the gains and losses are realized upon sale of the securities.

Earnings Per Share [Abstract]
Computations of Basic and Diluted Income Per Share	The Company utilizes the two-class method to calculate earnings per share. The two-class method allocates net income to each class of common stock and participating security. Unvested share-based payment awards granted to certain employees and board members entitle holders to the same rights as outstanding and vested common stock. These securities are considered to be participating securities and are included in the allocation for computing earnings per share under this method. Income is allocated to common shareholders and participating securities under the two-class method based upon the proportion of each to the total weighted average shares available. The computations of basic and diluted earnings per share for the periods ended December 31, 2015, 2014 and 2013 are as follows: December 31, 2015 2014 2013 (In thousands) Numerator: Net income to common shareholders $ 16,890 $ 10,594 $ 24,595 Net income allocated to participating securities - basic and diluted 182 72 625 Net income allocated to common shareholders - basic and diluted $ 16,708 $ 10,522 $ 23,970 Denominator: Denominator for basic earnings per common share 45,631 48,267 48,157 Denominator for diluted earnings per common share: Potentially dilutive securities—options 1,904 3,229 3,671 Potentially dilutive securities—restricted stock — — 762 Potentially dilutive securities—warrants — 79 352 Total weighted average diluted shares 47,535 51,575 52,942 Earnings per common share Basic $ 0.37 $ 0.22 $ 0.51 Diluted 0.35 0.21 0.46
