Accounting Policies [Abstract]
Organization	Note 1. Organization NewStar Financial, Inc. (the “Company”) 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 wholly owned investment management subsidiary, NewStar Capital LLC, are registered investment advisers and provide asset management services to institutional investors. The Company manages several private credit funds that co-invest loans originated through its leveraged finance lending platform. Through 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 and high yield bonds. 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. 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 and systems, as well as 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, 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 its risk exposure to single borrowers. From time to time, however, the Company's balance sheet exposure to a single borrower exceeds $35 million. Beginning in January 2016, the Company’s operations were divided into two reportable segments that represent its core businesses, Commercial Lending and Asset Management. The Commercial Lending segment represents our direct lending activities which are focused on providing a range of flexible senior secured debt options to mid-sized companies with annual cash flow (EBITDA) typically between $10 million and $50 million owned by private equity investment funds and managed by established professional alternative asset managers. The Asset Management segment represents our investment advisory activities which are focused on providing opportunities for qualified investors 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 Basis of Presentation These interim condensed consolidated financial statements include the accounts of the Company and its subsidiaries (collectively, “NewStar”) and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). All significant intercompany transactions have been eliminated in consolidation. These interim condensed financial statements include adjustments of a normal and recurring nature considered necessary by management to fairly present NewStar’s financial position, results of operations and cash flows. These interim condensed financial statements may not be indicative of financial results for the full year. The preparation of 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. The estimates most susceptible to change in the near-term are the Company’s estimates of its (i) allowance for credit losses, (ii) recorded amounts of deferred income taxes, (iii) fair value measurements used to record fair value adjustments to certain financial instruments, (iv) valuation of investments, (v) determination of other than temporary impairments and temporary impairments and (vi) impairment of goodwill and identified intangible assets. The interim condensed consolidated financial statements and notes thereto should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. Prior Period Reclassification Prior period amounts are reclassified wherever necessary to confirm with current period presentation.

Business Combinations [Abstract]
Acquisition and Disposition Activities	Note 3. Acquisition and Disposition Activities Acquisition As previously disclosed, 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, in October 2015. The Company now operates FOC Partners as NewStar Capital, a wholly owned subsidiary of the Company. During the first quarter of fiscal 2016, the Company completed its purchase price allocations and deemed the difference to be immaterial between the provisional and final purchase price allocations. As the result of facts and circumstances related to the customer contracts and related customer relationships, the Company reassessed the expected economic useful life of these contracts to be approximately 33 months instead of 12 months as originally estimated. Sale of NewStar Business Credit LLC On March 31, 2016, the Company sold its asset based lending business, NewStar Business Credit LLC (“Business Credit”) to a third party. The Company opted to sell Business Credit because it was faced with challenges from increasing competition with access to lower cost of funding. The sale resulted in a gain of $22.5 million, before transaction related costs of $2.5 million. The net gain is recorded in non-interest income on the accompanying consolidated statement of operations. Assets and Liabilities Held for Sale In September 2016, the Company commenced a process to sell the leasing line of business, NewStar Equipment Finance. As of that date certain assets and liabilities associated with Equipment Finance met the held-for-sale criteria. The potential disposal of Equipment Finance did not represent a strategic shift that will have a major effect on the Company’s operations and financial results and is, therefore, not classified as discontinued operations in accordance with ASU 2014-08, Presentation of Financial Statements (Topic 205) and Property and Equipment (Topic 360). The Company measured the asset and liabilities classified as held-for-sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a long-lived asset or disposal group until the date of sale. The Company will reassess the fair value of the assets and liabilities, less estimated costs to sell at each reporting period and until they are no longer classified as held for sale. T he Company that the approximate fair value less costs to sell exceeded the carrying value of the net assets and no loss was recorded. Equipment Finance is included within our Commercial Lending segment. For the three and nine months ended September 30, 2016, Equipment Finance contributed $0.8 million and $2.1 million, respectively, in pretax earnings. For the three and nine months ended September 30, 2015, Equipment Finance contributed $0.9 million and $2.3 million, respectively, in pretax earnings. The following table reconciles the major classes of assets and liabilities classified as held for sale and recorded at the carrying value, less estimated costs to sell as part of continuing operations in the Condensed Consolidated Balance Sheets.

Loans Held-for-Sale, Loans, Leases and Allowance for Credit Losses As of September 30, 2016 and December 31, 2015, loans held-for-sale consisted of the following: September 30, 2016 December 31, 2015 ($ in thousands) Leveraged Finance $ 435,351 $ 485,874 Gross loans held-for-sale 435,351 485,874 Deferred loan fees, net (5,633 ) (7,089 ) Total loans held-for-sale, net $ 429,718 $ 478,785 Loans classified as held-for-sale consist primarily of loans originated or purchased by the Company that are intended to be sold to third parties (including credit funds managed by the Company). During the three months ended September 30, 2016, the Company foreclosed on the previously held-for-sale impaired real estate loan, simultaneous with the foreclosure, the Company sold a portion of the property for $8.5 million and applied the proceeds to the principal loan balance. The remaining $15.8 million was transferred to Other Real Estate Owned (“OREO”). Loans held-for-sale are carried at the lower of either market value or aggregate cost, net of any deferred origination costs or fees. At September 30, 2016, loans held-for-sale include loans with an aggregate outstanding balance of $433.3 million that were intended to be sold to credit funds managed by the Company. The Company sold loans with an aggregate outstanding balance of $105.0 million for a net loss of $0.04 million to entities other than credit funds managed by the Company during the nine months ended September 30, 2016. The Company sold loans with an outstanding balance of $37.8 million for a net gain of $0.3 million to entities other than credit funds managed by the Company during the nine months ended September 30, 2015. As of September 30, 2016, and December 31, 2015, loans and leases consisted of the following: September 30, 2016 December 31, 2015 ($ in thousands) Leveraged Finance $ 3,263,985 $ 2,627,314 Business Credit — 342,281 Real Estate 17,742 100,732 Equipment Finance (1) — 173,253 Gross loans and leases (2) 3,281,727 3,243,580 Deferred loan fees and discount, net (28,864 ) (51,249 ) Allowance for loan and lease losses (65,865 ) (58,259 ) Total loans and leases, net $ 3,186,998 $ 3,134,072 (1) Equipment Finance has been transferred to assets held-for-sale as of September 30, 2016, see note 3. (2) Includes loans at fair value of $389.3 million and $0, respectively. 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 restructuring (“TDR”). The Company utilizes a number of analytical tools for the purpose of estimating probability of default and loss given default for its specialized lending groups. Management considers results from quantitative models in its Leveraged Finance lending group, which utilize Moody’s KMV RiskCalc credit risk model in combination with a proprietary qualitative model. The Real Estate lending group considers results from a proprietary model that we have developed to capture risk characteristics unique to the lending activities in that line of business. The results from models used by each lending group assist management in determining an appropriate obligor risk rating, which corresponds to a probability of default, as well as a loss given default. In each case, the determined probability of default and the loss given default are used to calculate an expected loss for those lending groups. Prior to classifying Equipment Finance as held-for-sale, management used similar models as its Leveraged Finance group. 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 better than a specified threshold are typically classified as “Pass”, and loans and leases rated worse than that threshold are typically classified as “Criticized”, a characterization that may apply to impaired loans, including TDR. As of September 30, 2016, $134.9 million of the Company’s loans were classified as “Criticized,” all of which were impaired loans, and $3.1 billion were classified as “Pass”. 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”. A TDR that performs in accordance with the terms of its 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. When the Company rates a loan above a certain risk rating threshold and the loan is deemed to be impaired, the Company will establish a specific allowance, if appropriate, and the loan will be analyzed and may be placed on non-accrual. If the asset deteriorates further, the specific allowance may increase, and the asset’s deterioration may ultimately result in a loss and charge-off. 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 and/or partial or full charge off 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 September 30, 2016, the Company had impaired loans with a balance of $156.9 million. Impaired loans with an aggregate outstanding balance of $137.6 million have been restructured and classified as TDRs. At September 30, 2016, additional funding commitments for TDRs totaled $5.1 million. As of September 30, 2016, the aggregate carrying value of equity investments in certain of the Company’s borrowers in connection with troubled debt restructurings totaled $11.0 million. Impaired loans with an aggregate outstanding balance of $87.3 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 payment status has been brought current. During the three and nine months ended September 30, 2016, the Company had a small recovery of $0.05 million and charged off $12.9 million, respectively, of non-accruing loan balances. During the three months ended September 30, 2016, the Company placed no loans on non-accrual status. During the nine months ended September 30, 2016, the Company placed loans with an aggregate outstanding balance of $14.3 million, on non-accrual status. During the three and nine months ended September 30, 2016, the Company recorded $3.2 million and $22.3 million, respectively, of net specific provisions for impaired loans. At September 30, 2016, the Company had a $36.2 million specific allowance for impaired loans with an aggregate outstanding balance of $105.1 million. At September 30, 2016, additional funding commitments for impaired loans totaled $9.1 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, or if the borrower is not in compliance additional funding commitments may be made at the Company’s discretion. As of September 30, 2016, the Company had loans totaling $16.3 million on non-accrual status which was greater than 60 days past due and classified as delinquent by the Company. Included in the $36.2 million specific allowance for impaired loans was $4.4 million related to delinquent loans. As of December 31, 2015, the Company had impaired loans with a balance of $193.2 million. At that date, impaired loans with an aggregate outstanding balance of $183.6 million had 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 troubled debt restructurings totaled $11.4 million. Impaired loans with an aggregate outstanding balance of $111.3 million were also on non-accrual status. 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. 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 $2.8 million related to delinquent loans. A summary of impaired loans is as follows: Investment, Net of Charge-offs Investment, Net of Unamortized Discount/Premium Unpaid Principal ($ in thousands) September 30, 2016 Leveraged Finance $ 149,697 $ 144,930 $ 180,240 Real Estate 7,160 7,160 7,160 Total $ 156,857 $ 152,090 $ 187,400 December 31, 2015 Leveraged Finance $ 157,446 $ 150,692 $ 188,453 Business Credit — — — Real Estate 34,941 34,915 38,286 Equipment Finance 772 709 772 Total $ 193,159 $ 186,316 $ 227,511 Recorded Investment Related Allowance for Credit Losses Recorded Investment, net, with a Related Allowance for Credit Losses Recorded Investment without a Related Allowance for Credit Losses Recorded Investment, net, without a Related Allowance for Credit Losses ($ in thousands) September 30, 2016 Leveraged Finance $ 105,099 $ 100,461 $ 44,598 $ 44,469 Real Estate — — 7,160 7,160 Total $ 105,099 $ 100,461 $ 51,758 $ 51,629 December 31, 2015 Leveraged Finance $ 113,397 $ 106,762 $ 44,049 $ 43,930 Business Credit — — — — Real Estate 7,705 7,705 27,236 27,210 Equipment Finance — — 772 709 Total $ 121,102 $ 114,467 $ 72,057 $ 71,849 During the three months ended September 30, 2016, the Company recorded a small recovery of $0.05 million on loans previously charged-off, and during the nine months ended September 30, 2016, the Company recorded net charge-offs of $14.2 million. During the three months ended September 30, 2015, the Company did not record any charge-offs or recoveries, and during the nine months ended September 30, 2015, the Company recorded net partial charge-offs of $3.9 million. The Company’s policy is to record a specific allowance for an impaired loan to cover the identified impairment of that loan. Based on the Company’s experience any potential charge-off of such loan would occur when any loan loss amount is considered to be confirmed. The Company may record the initial specific allowance related to an impaired loan in the same period as it records a partial charge-off in certain circumstances such as if the terms of a restructured loan are finalized during that period. When a loan is determined to be uncollectible, the specific allowance is charged off, which reduces the gross investment in the loan. While charge-offs of amounts previously reserved have no net impact on the carrying value of net loans and leases, charge-offs lower the level of the allowance for loan and lease losses; and, as a result, reduce the percentage of allowance for loans and leases to total loans and leases, and the percentage of allowance for loan and lease losses to non-performing loans. Below is a summary of the Company’s evaluation of its amortized cost portfolio and allowance for loan and lease losses by impairment methodology: Leveraged Finance Real Estate September 30, 2016 Investment Allowance Investment Allowance ($ in thousands) Collectively evaluated (1) (2) $ 2,725,028 $ 29,614 $ 10,582 $ 91 Individually evaluated (3) 149,697 36,160 7,160 — Total $ 2,874,725 $ 65,774 $ 17,742 $ 91 Leveraged Finance Business Credit Real Estate Equipment Finance December 31, 2015 Investment Allowance Investment Allowance Investment Allowance Investment Allowance ($ in thousands) Collectively evaluated (1) $ 2,469,868 $ 27,874 $ 342,281 $ 1,991 $ 65,791 $ 350 $ 172,481 $ 1,291 Individually evaluated (3) 157,446 26,447 — — 34,941 306 772 — Total $ 2,627,314 $ 54,321 $ 342,281 $ 1,991 $ 100,732 $ 656 $ 173,253 $ 1,291 (1) Represents loans and leases collectively evaluated for impairment in accordance with ASC 450-20, Loss Contingencies, and pursuant to amendments by ASU 2010-20 regarding allowance for unimpaired loans and leases. These loans had a weighted average risk rating of 5.1 at September 30, 2016, based on the Company’s internally developed 12 point scale for the Leveraged Finance and Real Estate loans. These loans and leases had a weighted average risk rating of 5.1 at December 31, 2015, based on the Company’s internally developed 12 point scale for the Leveraged Finance, Real Estate and Equipment Finance loans and leases. Business Credit Loans had a weighted average risk rating of 5.0 at December 31, 2015 based on the Company’s internally developed 10 point scale for Business Credit loans. (2) Excludes $389.3 million Leveraged Finance loans which the Company elected to record at fair value. (3) Represents loans individually evaluated for impairment in accordance with ASU 310-10, Receivables, Below is a summary of the Company’s investment in nonaccrual loans. Recorded Investment in Nonaccrual Loans September 30, 2016 December ($ in thousands) Leveraged Finance $ 87,291 $ 103,563 Business Credit — — Real Estate — 7,705 Equipment Finance — — Total $ 87,291 $ 111,268 Loans being restructured have typically developed adverse performance trends as a result of various factors, the result of which is an inability to comply with the terms of the applicable credit agreement governing the borrowers’ obligations to the Company. 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) development of a financial model with a forecast horizon that matches the term of the proposed restructuring, (ii) meetings with management of the borrower, (iii) engagement of third party consultants and (iv) other internal analyses. Once a restructuring proposal is developed, it is subject to approval by both the Company’s Underwriting and Investment Committee. Loans are only 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. 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 September 30, 2016 and December 31, 2015 is provided below: Group I Group II ($ in thousands) September 30, 2016 $ 137,614 $ 115,491 December 31, 2015 $ 183,573 $ 162,986 Note: A loan may be included in both restructuring groups, but not repeated within each group. For the three months ended September 30, 2016, the Company had no charge-offs, and for the nine months ended September 30, 2016 had $7.5 million, of partial charge-offs related to loans previously classified as TDR. As of September 30, 2016, 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. Below is a summary of the Company’s loans which were newly classified as TDR and existing TDR loans which subsequently defaulted, in each during the periods presented.

An age analysis of the Company’s delinquent receivables is as follows: 60-89 Days Past Due Greater than 90 Days Total Past Due Current Total Loans and Leases Investment > 60 Days & Accruing ($ in thousands) September 30, 2016 Leveraged Finance $ — $ 16,317 $ 16,317 $ 3,247,668 $ 3,263,985 $ — Real Estate — — — 17,742 17,742 — Total $ — $ 16,317 $ 16,317 $ 3,265,410 $ 3,281,727 $ — 60-89 Days Past Due Greater than 90 Days Total Past Due Current Total Loans and Leases Investment in > 60 Days & Accruing ($ in thousands) December 31, 2015 Leveraged Finance $ — $ 27,165 $ 27,165 $ 2,600,149 $ 2,627,314 $ 8,530 Business Credit — — — 342,281 342,281 — Real Estate — — — 100,732 100,732 — Equipment Finance — — — 173,253 173,253 — Total $ — $ 27,165 $ 27,165 $ 3,216,415 $ 3,243,580 $ 8,530 A general allowance is provided for loans and leases that are not impaired. 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 are internally risk-rated based on individual credit criteria, including loan type, loan 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 (prior to the latter’s transfer to held-for-sale), 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 terms and lender protections in determining a loan loss in the event of default. Prior to the sale of Business Credit, the Company utilized a proprietary model to risk rate the asset based loans on a monthly basis. This model captured 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 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 was 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. 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. At December 31, 2015, the Company enhanced its approach for determining the expected exposure at default to more precisely reflect loan and lease exposures. 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 the fourth quarter of 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, use of the peer group does assist management in identifying market trends and serves as an overall reasonableness check on the allowance for credit losses computation.

The methodology for determining the allowance for unfunded commitments is consistent with the methodology for determining the allowance for loan and lease losses. During the nine months ended September 30, 2016, the Company recorded a total provision for credit losses of $24.9 million. The Company increased its allowance for credit losses to $66.4 million as of September 30, 2016 from $58.7 million at December 31, 2015 as a result of an increase in the specific allowance for credit losses primarily related to the deterioration of four credits. In addition, the Company transferred four commercial real estate loans to loans held-for-sale which resulted in an additional $1.1 million of provision expense. The general allowance for credit losses covers probable incurred 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 incl

Investments in Debt Securities, Available-for-Sale Amortized cost of investments in debt securities as of September 30, 2016 and December 31, 2015 was as follows: September 30, 2016 December 31, 2015 ($ in thousands) Investments in debt securities—gross $ 105,020 $ 111,020 Unamortized discount (6,117 ) (6,765 ) Investments in debt securities—amortized cost $ 98,903 $ 104,255 The amortized cost, gross unrealized holding gains, gross unrealized holding losses, and fair value of available-for-sale securities at September 30, 2016 and December 31, 2015 were as follows: Amortized cost Gross unrealized holding gains Gross unrealized holding losses Fair value ($ in thousands) September 30, 2016 Collateralized loan obligations $ 98,903 $ 1 $ (8,090 ) $ 90,814 $ 98,903 $ 1 $ (8,090 ) $ 90,814 Amortized cost Gross unrealized holding gains Gross unrealized holding losses Fair value ($ in thousands) December 31, 2015 Collateralized loan obligations $ 104,255 $ — $ (10,078 ) $ 94,177 $ 104,255 $ — $ (10,078 ) $ 94,177 During the nine month period ended September 30, 2016, the Company did not purchase any debt securities and a $6.0 million investment in debt securities was redeemed at par. During the nine months ended September 30, 2015, the Company purchased $85.0 million of debt securities and $33.0 million investment in securities were redeemed at par. The Company did not sell any debt securities during the nine months ended September 30, 2016 or 2015. The Company did not record any net “Other-Than-Temporary Impairment” charges during the nine months ended September 30, 2016. The following is an analysis of the continuous periods during which the Company has held investment positions which were carried at an unrealized loss as of September 30, 2016 and December 31, 2015: September 30, 2016 Less than 12 Months Greater than or Equal to 12 Months Total ($ in thousands) Number of positions 2 19 21 Fair value $ 8,143 $ 81,434 $ 89,577 Amortized cost 8,461 89,206 97,667 Unrealized loss $ (318 ) $ (7,772 ) $ (8,090 ) 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 ) As a result of the Company’s evaluation of the securities, management concluded that the unrealized losses at September 30, 2016 and December 31, 2015 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 September 30, 2016, 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.” Maturities of debt securities classified as available-for-sale were as follows at September 30, 2016 and December 31, 2015: September 30, 2016 December 31, 2015 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 37,960 32,959 34,017 30,470 Due after ten years through fifteen years 60,943 57,855 70,238 63,707 Total $ 98,903 $ 90,814 $ 104,255 $ 94,177 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.

Debt Disclosure [Abstract]
Borrowings	Note 7. Borrowings Credit Facilities As of September 30, 2016 the Company had two credit facilities through certain of its wholly owned subsidiaries: (i) a $615.0 million credit facility with syndicated lenders agented by Wells Fargo Bank, National Association (“Wells Fargo”) to fund leveraged finance loans, and (ii) a $250.0 million credit facility with Citibank, N.A. (“Citibank”) to fund leveraged finance loans. The Company must comply with various covenants under these facilities. The breach of certain of these covenants could result in a termination event and the exercise of remedies if not cured. At September 30, 2016, the Company was in compliance with all such covenants. These covenants are customary and include, but are not limited to, failure to service debt obligations, failure to meet liquidity covenants and tangible net worth covenants, and failure to remain within prescribed facility portfolio delinquency, charge-off levels, and overcollateralization tests. The Company has a $615.0 million credit facility with syndicated lenders agented by Wells Fargo to fund leveraged finance loans. The credit facility had an outstanding balance of $293.9 million and unamortized deferred financing fees of $6.8 million as of September 30, 2016. In February 2016 and June 2016, the Company upsized this facility, which increased the commitment amount from $475.0 million to $615.0 million. Interest on this facility accrues at a variable rate per annum. The facility matures on August 10, 2020. The facility provides for a revolving reinvestment period which ends on August 10, 2018, with a two-year amortization period. The Company has a $250.0 million credit facility with Citibank to fund leveraged finance loans. The credit facility had an outstanding balance of $208.3 million and unamortized deferred financing fees of $2.6 million as of September 30, 2016. Interest on this facility accrues at a variable rate per annum. The facility matures on May 5, 2020. It provides for a revolving reinvestment period which ends on May 5, 2018, with a two-year amortization period. As a result of the ongoing process to sell its leasing business, NewStar Equipment Finance, the note purchase agreement with Wells Fargo under the terms of which Wells Fargo agreed to provide a $75.0 million credit facility to fund equipment leases and loans was reclassified to liabilities held-for-sale. The credit facility has an outstanding balance of $16.9 million and unamortized deferred financing fees of $0.2 million as of September 30, 2016. On September 15, 2016, the Company repaid the $350.0 million note purchase agreement with Credit Suisse that provided the financing to fund the purchase of broadly syndicated bank loans during the warehouse phase of the Arch Street CLO. The supplemental junior note commitment by NewStar Capital was also repaid in full. The notes were repaid from proceeds of the Arch Street CLO bond issuance. On March 31, 2016, the Company sold its membership interest in NewStar Business Credit LLC (“Business Credit”). In connection with the sale, the Company repaid all outstanding indebtedness of Business Credit, including amounts outstanding under the $175 million credit facility with a syndicate of lenders agented by DZ Bank AG Deutsche Zentral-Genossenschaftbank Frankfurt (“DZ Bank”) with an outstanding balance of $102.0 million and the $165.0 million credit facility with a syndicate of lenders agented by Wells Fargo with an outstanding balance of $135.4 million, each of which was terminated. The Company accelerated and recognized deferred financing fees of $1.1 million and $0.7 million, respectively, related to the warehouse facilities during the first quarter of 2016. Senior notes On April 22, 2015, the Company issued $300.0 million in aggregate principal amount of 7.25% Senior Notes due 2020 (the “2020 Notes”). On November 9, 2015, the Company issued an additional $80.0 million in aggregate principal amount of 2020 Notes. The 2020 Notes issued on November 9, 2015, were issued at a debt discount of $0.8 million which will amortize over the life of the 2020 Notes. The Company used a portion of the net proceeds from the April notes offering to repay in full its corporate credit facility with Fortress Credit Corp. The 2020 Notes mature on May 1, 2020, and bear interest at a rate of 7.25% per annum, which is payable semi-annually on May 1 and November 1 of each year. At any time prior to May 1, 2017, the Company may redeem up to 35% of the aggregate principal amount of the 2020 Notes with the net cash proceeds of certain public equity offerings at a price equal to 107.25% of the aggregate principal amount so redeemed, plus accrued and unpaid interest thereon provided that immediately following the redemption, at least 65% of the 2020 Notes that were originally issued remain outstanding. Additionally, at any time prior to May 1, 2017, the Company may redeem some or all of the 2020 Notes at a price equal to 100% of the aggregate principal amount, plus accrued and unpaid interest thereon and a make-whole premium. On or after May 1, 2017, the Company may redeem the 2020 Notes, in whole or in part, at redemption prices specified in the 2020 Notes plus accrued and unpaid interest thereon. In addition, if the Company undergoes a change of control, the Company will be required to make an offer to purchase each holder’s 2020 Notes at a price equal to 101% of the principal amount of the 2020 Notes, plus accrued and unpaid interest. As of September 30, 2016, unamortized deferred financing fees were $5.9 million. 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 2015, the Company drew an additional $75 million of these Subordinated Notes. The Company drew the remaining $25 million in January 2016. The Subordinated Notes were recorded at par less the initial relative fair value of the warrants issued in connection with the investment in December 2014 and January 2015, which was $55.4 million as of September 30, 2016 and $60.0 million as of December 31, 2015. 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 September 30, 2016, unamortized deferred financing fees were $5.1 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. 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. Term Debt Securitizations 2007-1 CLO. In June 2007, the Company completed a term debt securitization transaction. In conjunction with this transaction the Company established a separate single-purpose bankruptcy-remote subsidiary, NewStar Commercial Loan Trust 2007-1 (the “2007-1 CLO Trust”) and sold and contributed $600.0 million in loans and investments (including unfunded commitments), or portions thereof, to the 2007-1 CLO Trust. The Company remains the servicer of the loans. Simultaneously with the initial sale and contribution, the 2007-1 CLO Trust issued $546.0 million of notes to institutional investors. The Company retained $54.0 million, comprising 100% of the 2007-1 CLO Trust’s trust certificates. At September 30, 2016, the $97.4 million of outstanding drawn notes were collateralized by the specific loans and investments, principal collection account cash and principal payment receivables totaling $151.6 million. The 2007-1 CLO Trust permitted reinvestment of collateral principal repayments for a six-year period which ended in May 2013. During 2012, the Company purchased $0.2 million of the 2007-1 CLO Trust’s Class C notes. During 2010, the Company purchased $5.0 million of the 2007-1 CLO Trust’s Class D notes. During 2009, the Company purchased $1.0 million of the 2007-1 CLO Trust’s Class D notes. During 2009, Moody’s downgraded all of the notes of the 2007-1 CLO Trust. As a result of the downgrade, amortization of the 2007-1 CLO Trust changed from pro rata to sequential, resulting in scheduled principal payments thereafter made in order of the notes’ seniority until all available funds are exhausted for each payment. The Company receives a loan collateral management fee and excess interest spread. The Company also receives payments with respect to the classes of notes it owns in accordance with the transaction documents. The Company expects to receive a principal distribution as owner of the trust certificates when the term debt is retired. If loan collateral in the 2007-1 CLO Trust is in default under the terms of the indenture, the excess interest spread from the 2007-1 CLO Trust would not be distributed until the undistributed cash plus recoveries equals the outstanding balance of the defaulted loan or if the Company elected to remove the defaulted collateral.

On December 18, 2012, the Company completed a term debt securitization transaction. In conjunction with this transaction the Company established a separate single-purpose bankruptcy-remote subsidiary, NewStar Commercial Loan Funding 2012-2 LLC (the “2012-2 CLO”) and sold and contributed $325.9 million in loans and investments (including unfunded commitments), or portions thereof, to the 2012-2 CLO. The Company remains the servicer of the loans. Simultaneously with the initial sale and contribution, the 2012-2 CLO issued $263.3 million of notes to institutional investors. The Company retained $62.6 million, comprising 100% of the 2012-2 CLO’s membership interests, Class E notes, Class F notes, and subordinated notes. On June 12, 2015, the Company sold 100% of the 2012-2 CLO’s Class E Notes totaling $16.3 million to institutional investors. At September 30, 2016, the $260.2 million of outstanding drawn notes were collateralized by the specific loans and investments, principal collection account cash and principal payment receivables totaling $306.5 million. At September 30, 2016, unamortized deferred financing fees were $0.9 million. The 2012-2 CLO permitted reinvestment of collateral principal repayments for a three-year period which ended in January 2016. The Company receives a loan collateral management fee and excess interest spread. The Company also receives payments with respect to the classes of notes it owns in accordance with the transaction documents. The Company expects to receive a principal distribution as owner of the membership interests when the term debt is retired. If loan collateral in the 2012-2 CLO is in default under the terms of the indenture, the excess interest spread from the 2012-2 CLO may not be distributed if the overcollateralization ratio, or other collateral quality tests, are not satisfied.

On September 11, 2013, the Company completed a term debt securitization transaction through its separate single-purpose bankruptcy-remote subsidiary, NewStar Commercial Loan Funding 2013-1 LLC (the “2013-1 CLO”) and sold and contributed $247.6 million in loans and investments (including unfunded commitments), or portions thereof, to the 2013-1 CLO. The Company remains the servicer of the loans. Simultaneously with the initial sale and contribution, the 2013-1 CLO issued $338.6 million of notes to institutional investors. The Company retained $61.4 million, comprising 100% of the 2013-1 CLO’s membership interests, Class F notes, Class G notes, and subordinated notes. At September 30, 2016, the $338.6 million of outstanding drawn notes were collateralized by the specific loans and investments, principal collection account cash and principal payment receivables totaling $400.0 million. At September 30, 2016, unamortized deferred financing fees were $2.8 million.

The Company also receives payments with respect to the classes of notes it owns in accordance with the transaction documents. The Company expects to receive a principal distribution as owner of the membership interests when the term debt is retired.

Earnings Per Share [Abstract]
Earnings Per Share	Note 10. 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 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 income per share for the three and nine months ended September 30, 2016 and 2015 are as follows: Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 (In thousands) Numerator: Net income to common shareholders $ 8,644 $ 5,142 $ 17,894 $ 12,681 Net income allocated to participating securities - basic and diluted 157 57 302 137 Net income allocated to common shareholders - basic and diluted 8,487 5,085 17,592 12,544 Denominator: Denominator for basic earnings per common share 45,812 45,745 46,216 46,139 Denominator for diluted earnings per common share: Denominator for basic earnings per common share 45,812 45,745 46,216 46,139 Potentially dilutive securities - options — 2,494 — 2,566 Potentially dilutive securities – restricted stock — — — — Potentially dilutive securities - warrants — — — — Total weighted average diluted shares 45,812 48,239 46,216 48,705 Earnings per common share Basic $ 0.19 $ 0.11 $ 0.38 $ 0.27 Diluted $ 0.19 $ 0.11 $ 0.38 $ 0.26 Warrants to purchase common stock totaling 12,000,000 were not included in the computation of earnings per share for the three and nine months ended September 30, 2016 and 2015 due to the fact that the effect would be anti-dilutive. Stock options totaling 741,845 were not included in the computation of earnings per share for the three and nine months ended September 30, 2016 due to the fact that the effect would be anti-dilutive.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Variable Interest Entities	Note 11. Variable Interest Entities 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. Consolidated VIEs are disclosed in Note 7. 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 $20.4 million. The Clarendon Fund employs an independent investment professional who is responsible for reviewing and approving investment recommendations made to the Clarendon Fund by the Company. The following table sets forth the information with respect to the unconsolidated VIEs for which the Company holds a variable interest in as of September 30, 2016 and December 31, 2015: September 30, 2016 December 31, 2015 ($ in thousands) Unconsolidated VIE assets $ 408,553 $ 483,581 Unconsolidated VIE liabilities 359,693 362,383 Equity interest included on the Consolidated Balance Sheet 23,734 23,910 Maximum risk of loss (1) 24,152 24,327 (1) In October 2015, NewStar acquired FOC Partners, which now operates as NewStar Capital. At acquisition, NewStar Capital was the investment manager for six collateralized loan obligations and two sponsored funds and provided discretionary services to a series of separately managed accounts. The Company determined that it was not the primary beneficiary of any of acquired CLOs, sponsored funds or separately managed accounts; however, the Company determined that it had a variable interest in the Secured Value sponsored fund as it holds approximately one percent of the interest of the fund.

Commitments And Contingencies Disclosure [Abstract]
Financial Instruments with Off-Balance Sheet Risk	Note 12. 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: September 30, 2016 December 31, 2015 ($ in thousands) Unused lines of credit $ 287,172 $ 601,805 Standby letters of credit 8,754 8,696

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Total Return Swap	Note 13. Total Return Swap The Company was a participant in a Total Return Swap (“TRS”), which matured on March 31, 2016. We acted as the manager of the TRS and selected the specific loans to be subject to the TRS. The TRS did not qualify for hedge accounting treatment as it did not offset the risks of another investment position. The underlying referenced loan portfolio of the TRS was primarily large, liquid, broadly syndicated senior secure floating rate loans with Citibank, N.A. as the counterparty. 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 were not directly owned the Company, in return for an interest-type payment to Citibank. On December 4, 2014, NewStar TRS I LLC, a newly-formed wholly owned subsidiary of the Company, entered into the TRS. 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 December 15, 2014, we entered into an amendment to the TRS that increased the maximum value to $125.0 million, on March 2, 2015, we entered into an amendment 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. Upon maturity of the TRS, the Company purchased $138.9 million of the loans in the referenced portfolio. The majority of these loans were purchased to fund future CLOs of the Company and its wholly owned subsidiary NewStar Capital. The Company recorded these loans at fair value which was determined by using the The Company recorded interest income from the TRS portfolio of $2.2 million, interest expense from the TRS portfolio of $0.8 million, and a realized loss on the TRS of $6.1 million in the consolidated statement of operations for the nine months ended September 30, 2016. At December 31, 2015, the receivable and realized loss on the total return swap on the consolidated balance sheet and consolidated statements of operations consisted of the following: Net Receivable Net Realized Gains/(Losses) ($ 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 — The fair value of the TRS was 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 was reflected in the consolidated statements of operations as loss (gain) on total return swap. As of December 31, 2015, the fair value of the underlying referenced portfolio was $155.6 million. The Company's obligations under the TRS were non-recourse to it, and its exposure was limited to the value of the cash collateral which fluctuated from time to time depending on the market value of the underlying loans. The Company was required to cash collateralize a specified percentage of each loan included under the TRS in accordance with margin requirements. As of September 30, 2016 and December 31, 2015, the Company had cash collateral on deposit with Citibank of $0 and $56.5 million, respectively. The Company paid 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.

Fair Value Disclosures [Abstract]
Fair Value	Note 14. Fair Value ASC 820, Fair Value Measurements • 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. 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. Loans Loans designated to Credit Funds managed by NewStar Capital are recorded at fair value on a recurring basis. The Company has elected to apply the fair value option accounting to these loans which is consistent with the manner in which the Credit Funds are managed. The fair value of these loans are based on third party pricing services. These loans are classified as Level 2. During the nine months ended September 30, 2016, the Company recorded a $3.7 million gain from the change in fair value which was recorded in other miscellaneous income, net. Total return swap The fair value of the total return swap was based on third party pricing services who collect prices through a variety of methods including dealer runs, indicative sheets and online posts. The Company recorded the total return swap with Citibank as Level 2. At September 30, 2016, the Company no longer participated in the TRS. At December 31, 2015, the TRS was included within Other liabilities on the consolidated balance sheet. The TRS had a maximum notional amount of $175.0 million and was carried at an estimated fair value of $(4.4) million, comprised of $1.4 million of interest receivable and an unrealized loss of $5.8 million on the underlying loan portfolio. 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. During the nine months ended September 30, 2016, the Company recorded $4.2 million of specific allowance for credit losses related to “Collateral dependent impaired loans” measured at fair value at September 30, 2016, which was subsequently charged off when the impaired loans were transferred to the held-for-sale portfolio. During 2015, the Company recorded $0.3 million of specific allowance for credit losses related to “Collateral dependent impaired loans” measured at fair value. Loans held-for-sale Loans held-for-sale are carried at the lower of cost or fair value. Loans held-for-sale measured at fair value consist of loans that have had credit downgrades and/or have remained in the loans held-for-sale portfolio for a significant period of time. When fair value is determined to be the carrying value, the fair values of these loans are obtained through a third party pricing service or by using internally developed financial models. Inputs into the model-based valuations can include changes in market indexes, selling prices of similar loans, management’s assumption related to the 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. During the nine months ended September 30, 2016, the Company recorded a $5.3 million loss related to “Loans, held-for-sale” measured at fair value. During 2015, the Company recorded a $2.6 million loss related to “Loans, held-for-sale” measured at fair value. 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.

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 the three and nine months ended September 30, 2016 and 2015.

The methodologies for other financial instruments are discussed below. Cash and cash equivalents, restricted cash and cash collateral on deposit with custodians: The carrying amounts approximate fair value because of the short maturity of these instruments. Assets held-for-sale: The fair value is determined through the evaluation of the expected sale proceeds. 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. Liabilities held-for-sale: The carrying amounts approximate fair value. Other assets/other liabilities : Comprised of non-public investments and, through March 31, 2016, the total return swap. The non-public investments are carried within other assets at $17.2 million and $14.3 million, as of September 30, 2016 and December 31, 2015, respectively. These investments are in the form of equity or warrants and are obtained as part of the loan origination process. The investments are initially recorded at cost and reviewed quarterly. If the fair value is less than cost then the investment is written down to fair value with the necessary adjustment recorded through 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 is adjusted for discounts related to lack of liquidity. The Company classifies equity and warrants as Level 3. The total return swap, which was included in other liabilities as of December 31, 2015, was based on third party pricing services who collect prices through a variety of methods including dealer runs, indicative sheets and online posts. The Company classified the total return swap as Level 2.

Segment Reporting [Abstract]
Segment Reporting	Note 15. Segment Reporting Beginning in 2016, the Company has two reportable segments, Commercial Lending and Asset Management. Segment information is derived from the internal reporting system utilized by management. Revenues and expenses for segments reflect those revenue and expenses which can be specifically identified and have been assigned based on internally developed allocation methods. Results may be restated, when necessary, to reflect changes in organizational structure or allocation methodology. Any changes in allocations that may affect the reported results of any business segment will not affect the consolidated financial position or results of operations of the Company as a whole. Commercial Lending The Commercial Lending segment represents our direct lending activities which are focused on providing a range of flexible senior secured debt options to mid-sized companies with annual cash flow (EBITDA) typically between $10 million and $50 million owned by private equity investment funds and managed by established professional alternative asset managers. Asset Management The Asset Management segment represents our investment advisory activities which are focused on providing opportunities for qualified investors 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. The following tables presents the statement of operations and total assets for the Company’s reportable segments: Three Months Ended September 30, 2016 Commercial Lending Asset Management Consolidated Total Net interest income: $ 24,135 $ 1,123 $ 25,258 Provision for loan losses 3,570 — 3,570 Net interest income after provision 20,565 1,123 21,688 Noninterest income: Management fees — 2,888 2,888 Performance fees — 465 465 Other lending fees 2,871 75 2,946 Gain/(loss) on sale of loans and equipment 83 69 152 Other noninterest income (1) 1,059 3,456 4,515 Total noninterest income: 4,013 6,953 10,966 Non-interest expense 14,833 3,236 18,069 Income before income taxes $ 9,745 $ 4,840 $ 14,585 Income tax expense 5,941 Net income $ 8,644 (1) Includes fair value adjustments on Loans held-for-sale and fair value portfolio.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These interim condensed consolidated financial statements include the accounts of the Company and its subsidiaries (collectively, “NewStar”) and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). All significant intercompany transactions have been eliminated in consolidation. These interim condensed financial statements include adjustments of a normal and recurring nature considered necessary by management to fairly present NewStar’s financial position, results of operations and cash flows. These interim condensed financial statements may not be indicative of financial results for the full year. The preparation of 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. The estimates most susceptible to change in the near-term are the Company’s estimates of its (i) allowance for credit losses, (ii) recorded amounts of deferred income taxes, (iii) fair value measurements used to record fair value adjustments to certain financial instruments, (iv) valuation of investments, (v) determination of other than temporary impairments and temporary impairments and (vi) impairment of goodwill and identified intangible assets. The interim condensed consolidated financial statements and notes thereto should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2015.

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 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 income per share for the three and nine months ended September 30, 2016 and 2015 are as follows: Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 (In thousands) Numerator: Net income to common shareholders $ 8,644 $ 5,142 $ 17,894 $ 12,681 Net income allocated to participating securities - basic and diluted 157 57 302 137 Net income allocated to common shareholders - basic and diluted 8,487 5,085 17,592 12,544 Denominator: Denominator for basic earnings per common share 45,812 45,745 46,216 46,139 Denominator for diluted earnings per common share: Denominator for basic earnings per common share 45,812 45,745 46,216 46,139 Potentially dilutive securities - options — 2,494 — 2,566 Potentially dilutive securities – restricted stock — — — — Potentially dilutive securities - warrants — — — — Total weighted average diluted shares 45,812 48,239 46,216 48,705 Earnings per common share Basic $ 0.19 $ 0.11 $ 0.38 $ 0.27 Diluted $ 0.19 $ 0.11 $ 0.38 $ 0.26
