	Note 1. Organization
	NewStar Financial, Inc. (the “Company”), a Delaware corporation, is a specialized commercial finance company focused on meeting the complex financing needs of companies and private investors in the middle market. The Company focuses primarily on the direct origination of loans and equipment leases through teams of credit-trained bankers and marketing officers organized around key industry and market segments. The Company’s marketing and direct origination efforts target private equity sponsors, mid-sized companies, corporate executives, regional banks, real estate investors and a variety of other referral sources and financial intermediaries to source new customer relationships and lending opportunities. The Company’s emphasis on direct origination is an important aspect of its marketing and credit strategy because it provides direct access to customers’ management teams and enhances the Company’s 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, it has significant input into customers’ financial strategies and capital structures. The Company also participates in loans as a member of a lending group. The mix of the Company’s originations may vary from period to period. 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.
	The Company operates as a single segment, and it derives revenues from four specialized lending groups that target market segments in which it believes that it has a competitive advantage:

		•	Leveraged Finance, provides senior, secured cash flow loans and, to a lesser extent, second lien loans, which are primarily used to finance acquisitions of mid-sized companies with annual cash flow (EBITDA) typically between $5 million and $30 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, manages an existing portfolio of first mortgage debt which was sourced primarily to finance acquisitions of commercial real estate properties typically valued between $10 million and $50 million by professional commercial real estate investors; and

		•	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.

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”) and Arlington Fund (defined below), its variable interest entity (“VIE”) for which the Company is deemed to be the primary beneficiary and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). All significant intercompany transactions have been eliminated in consolidation.
	On April 8, 2013, the Company announced that it had 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 Arlington Fund, the Company retains full discretion over Arlington Fund’s investment decisions, subject to usual and customary limitations, and earns management fees as compensation for its services. Consolidation of the financial results of Arlington Fund with the Company’s results of operations and statements of financial position began in April 2013.
	Use of Estimates
	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. Estimates most susceptible to change in the near-term are the Company’s estimates of their allowance for credit losses, impairment of loans and recorded amounts of deferred income taxes.
	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 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. If a decline in the fair value of a security below its amortized cost is judged by management to be other than temporary, the cost basis of the security is written down to fair value and the amount of the write-down is included in operations. 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 Company also recognizes an other than temporary impairment on an investment in debt security in an unrealized loss position if (i) the Company does not expect full recovery of its amortized cost based on the estimate of cash flows expected to be collected, (ii) the Company intends to sell the debt security, or (iii) it is more likely than not that the Company will be required to sell the debt security prior to recovery.
	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. These loans are carried at the lower of aggregate cost, net of any deferred origination costs or fees, or market 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 changes in economic conditions, credit availability, industry 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 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 terms 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 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 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. There have been no material modifications to the allowance for credit losses methodology during 2013. 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 a judgmental amount which is governed by a score card system comprised of ten individually weighted 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. 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. 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.
	Impaired loans at December 31, 2013 were in Real Estate, Leveraged Finance, and Business Credit over a range of industries impacted by the then current economic environment including the following: Buildings and Commercial Real Estate, Broadcast and Entertainment, Nondurable Consumer Products, Energy and Chemical Services, Financial Services, Healthcare, Printing and Publishing, Restaurants, and Industrial and Other Business Services. For impaired Leveraged 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 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. These amounts are amortized using the straight-line method into earnings as interest expense ratably over the contractual term of the facility.

	Property and Equipment
	Property and equipment are carried at cost and are depreciated or amortized on a straight-line basis over the following useful lives:


	Leasehold improvements	Shorter of estimated life or remaining lease term
	Computer equipment and software	3 years
	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, 2013, 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 as fee income.
	Asset Management Income
	NewStar Financial, Inc. earns asset management income for investment management services performed for the NewStar Credit Opportunities Fund, Ltd. 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
	Effective January 1, 2006, the Company adopted ASC 718 (Share-Based Payment), which requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values on the grant date. The Company adopted ASC 718 using the prospective method.
	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 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 Method of Accounting
	As the result of a troubled debt restructuring, the Company may acquire a portion of the equity in the borrower. 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.
	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, 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.
	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.

Loans Held-for-Sale, Loans and Leases, and Allowance for Credit Losses	'

	Note 3. Loans Held-for-Sale, Loans and Leases, and Allowance for Credit Losses
	The Company operates as a single segment, and derives revenues from four specialized lending groups that target market segments in which it believes it has a competitive advantage:

		•		Leveraged Finance, provides senior, secured cash flow loans and, to a lesser extent, second lien 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, manages an existing portfolio of first mortgage debt which was sourced 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 small and 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 NewStar Arlington Fund LLC (“Arlington Fund”), a credit fund managed by the Company formed in April 2013) or impaired loans for which a sale of the loan is expected as a result of a workout strategy. At December 31, 2013 loans held-for-sale were $14.9 million and consisted of leveraged finance loans to three borrowers.
	These loans are carried at the lower of aggregate cost, net of any deferred origination costs or fees, or market value.
	As of December 31, 2013 and 2012, loans held-for-sale consisted of the following:


			December 31,				December 31,
			2013				2012
			($ in thousands)
	Leveraged Finance		$	14,897			$	52,120

	Gross loans			14,897				52,120
	Deferred loan fees, net			(66	)			(518	)

	Total loans, net		$	14,831			$	51,602

	The Company sold loans with an outstanding balance totaling $32.0 million for an aggregate gain of $0.1 million to entities other than the NewStar Credit Opportunities Fund, Ltd. (“NCOF”) or the Arlington Fund during 2013. The Company sold loans with an aggregate outstanding balance of $45.1 million for a gain of $0.3 million to entities other than the NCOF during 2012. The Company sold loans with an aggregate outstanding balance of $31.3 million for a gain of $0.1 million to entities other than the NCOF during 2011.

	As of December 31, 2013 and 2012, loans and leases consisted of the following:


			December 31,
			2013				2012
			($ in thousands)
	Leveraged Finance		$	1,965,130			$	1,422,415

	Total loans and leases, net		$	2,266,677			$	1,720,789

	On December 27, 2013, the NCOF paid off the outstanding notes of its term debt securitizationat par. As of December 31, 2013, we had purchased $217.9 million of the $276.5 million of outstanding loans previously owned by the NCOF.
	As of December 31, 2013 and 2012, Equipment Finance products totaled $38.4 million and $17.3 million, respectively, and are included in the Business Credit balances.
	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, 2013, $190.6 million of the Company’s loans were classified as “Criticized”, including $177.5 million of the Company’s impaired loans, and $2.1 billion were classified as “Pass”. As of December 31, 2012, $267.2 million of the Company’s loans were classified as “Criticized”, including $237.6 million of the Company’s impaired loans, and $1.5 billion were classified as “Pass”. All of the loans held by the Arlington Fund were classified as “Pass” as of December 31, 2013.
	When the Company rates a loan above a certain risk rating threshold, 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, 2013, the Company had impaired loans with an aggregate outstanding balance of $271.0 million. Impaired loans with an aggregate outstanding balance of $240.3 million have been restructured and classified as TDR. As of December 31, 2013, the aggregate carrying value of equity investments in certain of the Company’s borrowers in connection with troubled debt restructurings totaled $6.9 million. Impaired loans with an aggregate outstanding balance of $70.7 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 2013, the Company charged off $15.8 million of outstanding non-accrual loans. During 2013, the Company placed loans with an aggregate outstanding balance of $48.9 million on non-accrual status and took loans with an aggregate outstanding balance of $34.8 million off of non-accrual status. During 2013, the Company recorded $11.2 million of net specific provisions for impaired loans. At December 31, 2013, the Company had a $23.3 million specific allowance for impaired loans with an aggregate outstanding balance of $154.7 million. At December 31, 2013, additional funding commitments for impaired loans totaled $17.6 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, 2013, $5.1 million of loans on non-accrual status were greater than 60 days past due and classified as delinquent by the Company. Included in the $23.3 million specific allowance for impaired loans was $1.2 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. The commercial real estate properties had an aggregate carrying value of $13.5 million as of December 31, 2013 and $13.0 million as of December 31, 2012.
	As of December 31, 2012, the Company had impaired loans with an aggregate outstanding balance of $324.4 million. Impaired loans with an aggregate outstanding balance of $263.7 million have been restructured and classified as TDR. As of December 31, 2012, the aggregate carrying value of equity investments in certain of the Company’s borrowers in connection with troubled debt restructurings totaled $7.7 million. Impaired loans with an aggregate outstanding balance of $72.7 million were also on non-accrual status. During 2012, the Company charged off $19.1 million of outstanding non-accrual loans and recovered $1.6 million of previously charged-off impaired loan outstanding balances. During 2012, the Company took previously identified non-accrual loans with an aggregate outstanding balance of $16.2 million as of December 31, 2011 off non-accrual status and placed loans with an aggregate outstanding balance of $22.7 million as of December 31, 2012 on non-accrual status. During 2012, the Company recorded $16.7 million of net specific provisions for impaired loans. At December 31, 2012, the Company had a $30.2 million specific allowance for impaired loans with an aggregate outstanding balance of $192.1 million. At December 31, 2012, additional funding commitments for impaired loans totaled $33.6 million. As of December 31, 2012, $62.7 million of loans on non-accrual status were greater than 60 days past due and classified as delinquent by the Company. Included in the $30.2 million specific allowance for impaired loans was $6.4 million related to delinquent loans.
	A summary of impaired loans is as follows:

During 2013, 2012 and 2011 the Company recorded net partial charge-offs of $17.8 million, $26.8 million and $38.0 million, respectively. During 2013, 2012 and 2011 the Company recorded recoveries of previously charged-off loans of $0.1 million, $1.6 million and $0.9 million, respectively. The Company’s general policy is to record a specific allowance for an impaired loan when the Company determines that it is doubtful that it will be able to collect all amounts due according to the contractual terms of the loan. Any partial 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, and reduces the gross investment in the loan.
While charge-offs typically have no net impact on the carrying value of net loans, charge-offs lower the level of the allowance for loan losses; and, as a result, reduce the percentage of allowance for loans to total loans, and the percentage of allowance for loan losses to non-performing loans.

Loans being restructured typically develop adverse performance trends as a result of internal or external factors, the result of which is an inability to comply with the terms of the applicable credit agreement governing their 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) 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 upon 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 charge-offs

A summary of the types of concessions that the Company made with respect to TDRs at December 31, 2013 and 2012 is provided below:


($ in thousands)		Group I				Group II
December 31, 2013		$	240,319			$	164,150
December 31, 2012		$	263,670			$	145,328
Note: A loan may be included in both restructuring groups, but not repeatedly within each group.
For 2013 and 2012, the Company had partial charge-offs totaling $8.8 million and $12.6 million, respectively, related to loans previously classified as TDR. As of December 31, 2013, the Company had not removed the TDR classification from any loan previously identified as such.
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 based on the terms of the restructuring. If a charge-off is taken on a restructured loan, interest will typically move to a “cash basis” where it is taken into income only upon receipt or be placed on non-accrual. Loans will typically not be returned to accrual status until at least six months of contractual payments have been made in a timely manner. Additionally, at the time of a restructuring and quarterly thereafter, an impairment analysis is undertaken to determine the level of impairment on the loan.
Below is a summary of the Company’s loans which were classified as TDR.

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 changes in economic conditions, credit availability, industry 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 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 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 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 is providing capital on a transitional basis to the Arlington Fund. At December 31, 2013, the expected loss on Arlington Fund was zero and no allowance was recorded. If the duration of the Company’s investment in Arlington Fund or its assumptions regarding conditions in the capital markets were to change, it may be necessary for the Company to record an allowance for credit losses in the future.
The Company’s acquisition of the pool of loans from NCOF during December 2013 was recorded at fair value. At December 31, 2013, there had been no credit deterioration since the acquisition and as such, no allowance related to these loans was deemed necessary. We will reevaluate the need for a credit allowance on a quarterly basis.
If the Company determines that additional 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.
Additionally, when determining the amount of the general allowance, the Company supplements the base amount with a judgmental amount which is governed by a score card system comprised of ten individually weighted 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. 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. 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.

Included in the allowance for credit losses at December 31, 2013 and 2012 is an allowance for unfunded commitments of $0.5 million and $0.3 million, respectively, which is recorded as a component of other liabilities on the Company’s consolidated balance sheet with changes recorded in the provision for credit losses on the Company’s consolidated statement of operations. The methodology for determining the allowance for unfunded commitments is consistent with the methodology for determining the allowance for loan and lease losses.
During 2013, the Company recorded a total provision for credit losses of $9.7 million. The Company decreased its allowance for credit losses to $41.9 million as of December 31, 2013 from $50.0 million at December 31, 2012. The Company had $17.8 million of net charge-offs of impaired loans with a specific allowance and reduced its general allowance for credit losses by 98 basis points during 2013, offset by new specific provisions for credit losses. 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 troubled debt restructurings, as a percentage of “Loans and leases, net” was 12% as of December 31, 2013 and 19% as of December 31, 2012. The decrease is primarily due to the better credit quality of the acquired NCOF portfolio purchase and the consolidation of the Arlington Fund as a VIE.
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, 2013 in light of the estimated known and inherent risks identified through its analysis.

	The Company did not record any net Other Than Temporary Impairment charges during 2013, 2012 or 2011.

	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, 2013 and 2012:

	Unrealized loss		$	0			$	954			$	954

As a result of the Company’s evaluation of the securities, management concluded that the unrealized losses at December 31, 2013 and 2012 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, 2013, 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 December 31, 2013 and 2012 (maturities of asset-backed securities have been allocated based upon estimated maturities, assuming no change in the current interest rate environment):

Credit Facilities

As of December 31, 2013 the Company had four credit facilities: (i) a $275 million credit facility with Wells Fargo Bank, National Association (“Wells Fargo”) to fund leveraged finance loans, (ii) a $125 million credit facility with DZ Bank AG Deutsche Zentral-Genossenschaftbank Frankfurt (“DZ Bank”) to fund asset-based loans, (iii) a $75 million credit facility with Wells Fargo to fund asset-based loans, and (iv) a $75 million credit facility with Wells Fargo to fund new equipment lease origination. As of December 31, 2013, Arlington Fund had one credit facility, consisting of a $147.0 million of Class A Notes (as defined below) with Wells Fargo and $28.0 million of Class B Notes (as defined below) with the Company. The liability under the Class B Notes is eliminated in consolidation in accordance with GAAP.

The Company has a $275.0 million credit facility with Wells Fargo to fund leverage finance loans with the ability to further increase the commitment amount to $325.0 million, subject to lender approval and other customary conditions. On November 26, 2013, the Company entered into an amendment to this credit facility which among other things increased the commitment amount to $275.0 million from $175.0 million, with the ability to further increase the commitment amount to $325.0 million, and modified the concentration limits. The credit facility had an outstanding balance of $182.5 and unamortized deferred financing fees of $3.3 million as of December 31, 2013. The facility provides for a revolving reinvestment period which ends on November 5, 2015 with a two-year amortization period. The Company must comply with various covenants, the breach of which could result in a termination event if not cured. These covenants include, but are not limited to, failure to service debt obligations, failure to maintain minimum levels of liquidity, and failure to meet tangible net worth covenants and overcollateralization tests. At December 31, 2013, the Company was in compliance with all such covenants. Interest on this facility accrued at a variable rate per annum.

The Company has a $125.0 million credit facility with DZ Bank that had an outstanding balance of $82.2 million and unamortized fees of $0.7 million as of December 31, 2013. Interest on this facility accrues at a variable rate per annum. As part of the agreement, there is a minimum interest charge of $1.9 million per annum. If the facility is not utilized to cover this minimum requirement, then a make-whole fee is assessed to satisfy the minimum requirement. The Company is permitted to use the proceeds of borrowings under the credit facility to fund advances under asset-based loan commitments. The commitment amount under the credit facility matures on June 30, 2015.

The Company has a $75.0 million credit facility with Wells Fargo to fund asset-based loan origination. The credit facility had an outstanding balance of $59.4 million and unamortized deferred financing fees of $0.4 million as of December 31, 2013. Interest on this facility accrues at a variable rate per annum. The credit facility may be increased to an amount up to $150.0 million subject to lender approval and other customary conditions. The credit facility matures on December 7, 2015. The Company must comply with various covenants, the breach of which could result in a termination event if not cured. These covenants include, but are not limited to, failure to service debt obligations, net worth covenants, interest coverage ratios, minimum excess availability and violations of pool default and charged off tests.

The Company has a note purchase agreement with Wells Fargo under the terms of which Wells Fargo agreed to provide a $75.0 million credit facility to fund new equipment lease originations. The credit facility matures on November 16, 2016 subject to early termination or extension. The Company must comply with various covenants, the breach of which could result in a termination event if not cured. These covenants include, but are not limited to, failure to service debt obligations, failure to maintain minimum levels of liquidity, failure to hedge portfolio interest rate risk, failure to meet tangible net worth covenants and violations of pool default and delinquency tests. The credit facility had an outstanding balance of $8.0 million and unamortized deferred financing fees of $0.9 million as of December 31, 2013.

On April 4, 2013, Arlington Fund entered into an agreement establishing $147.0 million of Class A Notes and $28.0 million of Class B Notes to partially fund eligible middle market loan origination. Wells Fargo has committed to fund the Class A Notes as the initial Class A lender and the Company has committed to fund the Class B Notes as the initial Class B lender. Advances under the Class A Notes and the Class B Notes may be drawn, repaid, and drawn again subject to availability under the a borrowing base. The Class A Notes and the Class B Notes provide for a reinvestment period of one year ending on April 4, 2014, unless a one year extension is requested, followed by a three year amortization period. The Class A Notes had an outstanding balance of $120.3 million and unamortized deferred financing fees of $1.0 million as of December 31, 2013. The liability under the Class B Notes is eliminated in consolidation in accordance with GAAP.

Corporate Credit Facility

On January 5, 2010, the Company entered into a note agreement with Fortress Credit Corp., which was subsequently amended on August 31, 2010, January 27, 2012, November 5, 2012, and December 4, 2012. The agreement was amended and restated on May 13, 2013 and further amended on June 3, 2013. The credit facility, as amended, consists of a $200.0 million term note with Fortress Credit Corp. as agent, which consists of the existing outstanding balance of $100.0 million (the “Existing Funding”), an initial funding of $70.0 million (the “Initial Funding”), and two subsequent borrowings, of $5.0 million (the “Delay Draw Term A”) and $25.0 million (the “Delay Draw Term B”). The Existing Funding, the Initial Funding, and the Delay Draw Term A mature on May 11, 2018. The Delay Draw Term B matures on June 3, 2016. The Initial Funding, the Existing Funding and the Delay Draw Term A accrue interest at the London Interbank Offered Rate (LIBOR) plus 4.50% with an interest rate floor of 1.00%. The Delay Draw Term B accrues interest at LIBOR plus 3.375% with an interest rate floor of 1.00%.

The Company is permitted to use the proceeds of borrowings under the credit facility for general corporate purposes including, but not limited to, funding loans, working capital, paying down outstanding debt, acquisitions and repurchasing capital stock and dividend payments up to $37.5 million, The $37.5 million may be adjusted upward by the amount of fiscal year-end net income excluding depreciation and amortization expense.

The term note may be prepaid at any time subject to a prepayment fee of 1.00% which is payable in the case of certain prepayments made prior to May 13, 2014. The term note may be prepaid at par in the event of a change of control. As of December 31, 2013, the term note had an outstanding principal balance of $200.0 million and unamortized deferred financing fees of $5.0 million.

Subordinated debt—Fund membership interest

As of December 31, 2013, the Company had purchased membership interests totaling $5.0 million in Arlington Fund and a third-party investor had purchased membership interests totaling $30.0 million. As a result of consolidating Arlington Fund as a variable interest entity, or VIE, the membership interests representing equity ownership of Arlington Fund are characterized as debt in the Company’s consolidated statement of financial position. The Company applies an imputed interest rate to that debt and records the resulting interest expense in its consolidated statement of operations. The actual return on investments in Arlington Fund’s membership interests may or may not equal the imputed rate applied to the membership interests that are characterized as debt. In the consolidation, the Company eliminates 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.

Term Debt Securitizations

In June 2006 the Company completed a term debt transaction. In conjunction with this transaction the Company established a separate single-purpose bankruptcy remote subsidiary, NewStar Commercial Loan Trust 2006-1 (the “2006 CLO Trust”) and contributed $500 million in loans and investments (including unfunded commitments), or portions thereof, to the 2006 CLO Trust. The Company remains the servicer of the loans. Simultaneously with the initial contributions, the 2006 CLO Trust issued $456.3 million of notes to institutional investors. The Company retained $43.8 million, comprising 100% of the 2006 CLO Trust’s trust certificates. At December 31, 2013, the $164.4 million of outstanding drawn notes were collateralized by the specific loans and investments, principal collection account cash and principal payment receivables totaling $208.2 million. At December 31, 2013, deferred financing fees were $0. The 2006 CLO Trust permitted reinvestment of collateral principal repayments for a five-year period which ended in June 2011. During 2011, the Company repurchased $7.0 million of the 2006 CLO Trust’s Class C notes, $6.0 million of the 2006 CLO Trust’s Class D notes and $2.0 million of the 2006 CLO Trust’s Class E notes. During 2010, the Company repurchased $3.0 million of the 2006 CLO Trust’s Class D notes and $3.0 million of the 2006 CLO Trust’s Class E notes. During 2009, the Company repurchased $6.5 million of the 2006 CLO Trust’s Class D notes and $1.8 million of the 2006 CLO Trust’s Class E notes. During 2008, the Company repurchased $3.3 million of the 2006 CLO Trust’s Class D and $2.5 million of the 2006 CLO Trust’s Class E notes, respectively. During 2009, Moody’s downgraded all of the notes of the 2006 CLO Trust. As a result of the downgrade, amortization of the 2006 CLO Trust changed from pro rata to sequential, resulting in future scheduled principal payments made in order of the notes seniority until all available funds are exhausted for each payment. During 2010, Standard and Poor’s downgraded the Class A-1 notes, the Class A-2 notes, the Class C notes, the Class D notes and the Class E notes of the 2006 CLO Trust. The downgrade did not have any material consequence as the amortization of the 2006 CLO Trust changed from pro rata to sequential after the Moody’s downgrade in 2009. During 2011, Moody’s upgraded its ratings of all of the notes of the 2006 CLO Trust. During the third quarter of 2012, Fitch affirmed its ratings of all of the notes of the 2006 CLO Trust. During the fourth quarter of 2012, Standard and Poor’s upgraded the Class D notes and the Class E notes and affirmed the rating of the Class A-1 notes, the Class A-2 notes, the Class B notes and the Class C notes of the 2006 CLO Trust.

The Company receives a loan collateral management fee and excess interest spread. The Company expects to receive a principal distribution when the term debt is retired. If loan collateral in the 2006 CLO Trust is in default under the terms of the indenture, the excess interest spread from the 2006 CLO Trust could 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. The Company may have defaults in the 2006 CLO Trust in the future. If the Company does not elect to remove any future defaulted loans, it would not expect to receive excess interest spread payments until the undistributed cash plus any recoveries equal the outstanding balances of defaulted loan collateral.

On January 7, 2010, the Company completed a term debt securitization. In conjunction with this transaction the Company established a separate single-purpose bankruptcy-remote subsidiary, NewStar Commercial Loan Trust 2009-1 (the “2009-1 CLO Trust”) and contributed $225 million in loans and investments (including unfunded commitments), or portions thereof, to the 2009-1 CLO Trust at close.

The Company retained all of the Class C and subordinated notes, which totaled approximately $87.9 million, representing 32% of the value of the collateral pool. The 2009-1 CLO Trust was a static pool of loans that did not permit for reinvestment of collateral principal repayments. The 2009-1 CLO Trust was callable without penalty on the distribution date in July 2011 and on each distribution date thereafter. On August 1, 2011, the Company called the 2009-1 CLO Trust and redeemed the notes without penalty and recognized a total of $3.0 million of interest expense due to the accelerated amortization of deferred financing fees and unamortized discount.

	On June 7, 2011, the Company entered into a five-year, $68.0 million financing arrangement with Macquarie Bank Limited backed primarily by a portfolio of commercial mortgage loans previously originated by the Company. The financing was structured as a master repurchase agreement under which the Company sold the portfolio of commercial mortgage loans to Macquarie for an aggregate purchase price of $68.0 million. The Company also agreed to repurchase the commercial mortgage loans from time to time (including a minimum quarterly amount), and agreed to repurchase all of the commercial mortgage loans by June 7, 2016. Upon the repurchase of a commercial mortgage loan, the Company is obligated to repay the principal amount related to such mortgage loan plus accrued interest (at a rate based on LIBOR plus a margin) to the date of repurchase. The Company will continue to service the commercial mortgage loans. On October 2, 2013, the Company entered into an amendment to this financing arrangement which, among other things, extended the date it had agreed to repurchase all of the commercial mortgage loans by one year to June 7, 2017, provided for $25.5 million of additional advances for existing eligible assets owned by the Company, allowed for the advance of up to $15.0 million to fund an additional commercial mortgage loan, and released $41.1 million of principal payments to the Company as unrestricted cash. The facility accrues interest at a variable rate per annum, which was 5.17% as of December 31, 2013. As of December 31, 2013, unamortized deferred financing fees were $1.3 million and the outstanding balance was $68.0 million. During 2013, the Company made principal payments totaling $3.2 million and borrowed $40.5 million. As part of the amended agreement, there is a minimum aggregate interest margin payment of $9.2 million required to be made over the life of the facility. The Company cannot control the rate at which the underlying commercial mortgage loans are repaid. If the facility is not utilized to cover this minimum requirement, then a make-whole fee is required to be made to satisfy the minimum aggregate interest margin payment.

	Stock Options
	Under the Company’s 2006 Incentive Plan, the Company’s compensation committee may grant options to purchase shares of common stock. Stock options may either be incentive stock options (“ISOs”) or non-qualified stock options. ISOs may only be granted to officers and employees. The compensation committee will, with regard to each stock option, determine the number of shares subject to the stock option, the manner and time of exercise, vesting, and the exercise price, which will not be less than 100% of the fair market value of the common stock on the date of the grant. The shares of common stock issuable upon exercise of options or other awards or upon grant of any other award may be either previously authorized but unissued shares or treasury shares.
	On March 18, 2009 the Company completed an option exchange program with its senior management, including the Company’s principal executive officer, principal financial officer and other named executive officers whereby in exchange for a grant of stock options priced at fair market value on March 18, 2009, each executive agreed to surrender to the Company for cancellation the option award granted to him on December 13, 2006 and to abide by the terms of a lock-up agreement. The lock-up agreement requires 50% of the net proceeds from any exercise or partial exercise of the option received as part of the March 2009 option exchange program be held by the Company until the one-year anniversary of the time when the executive ceases to be employed by the Company. During that time, such portion of the proceeds from the option exercise is subject to forfeiture if the senior executive violates the restrictive covenants in his employment agreement with the Company. The option exchange program resulted in the forfeiture of 1,985,262 options to the Company in exchange for 2,725,000 new stock option grants. The options granted vested in three equal installments on each of the first three anniversaries of the March 18, 2009 grant date and have a seven-year life.

Consolidated Variable Interest Entity	'
	Note 12. Consolidated Variable Interest Entity
	On April 8, 2013, the Company announced that it had 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 Arlington Fund, the Company retains full discretion over Arlington Fund’s investment decisions, subject to usual and customary limitations, and earns management fees as compensation for its services. For 2013, the management fee was $0.5 million. The Company is deemed to be the primary beneficiary of Arlington Fund. Consolidation of the financial results of Arlington Fund with the Company’s results of operations and statements of financial position began in April 2013.
	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 has committed to fund the Class A Notes as the initial Class A lender and the Company has committed to fund the Class B Notes as the initial Class B lender. Advances under the Class A Notes and the Class B Notes may be drawn, repaid, and drawn again subject to availability under the a borrowing base. The Class A Notes and the Class B Notes provide for a reinvestment period of one year ending on April 4, 2014, unless a one year extension is requested, followed by a three year amortization period. For 2013 interest expense on the Class B Notes totaled $0.7 million.
	Although the Company consolidates all of the assets and liabilities of Arlington Fund, its maximum exposure to loss is 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 define the Company’s economic relationship with Arlington Fund but are eliminated upon consolidation. The Company manages the assets of Arlington Fund solely for the benefit of its lenders and investors. If the Company were to liquidate, the assets of Arlington Fund would not be available to the Company’s general creditors. Conversely, the investors in the debt of Arlington Fund have no recourse to the Company’s general assets. Therefore, the Company does not consider this debt its obligation.
	As of December 31, 2013, the Company had purchased membership interests totaling $5.0 million in Arlington Fund and a third-party investor had purchased membership interests totaling $30.0 million. As a result of consolidating Arlington Fund as a variable interest entity, or VIE, the membership interests representing equity ownership of Arlington Fund are characterized as debt in the Company’s consolidated statement of financial position. The Company applies an imputed interest rate to that debt and records the resulting interest expense in its consolidated statement of operations. The actual return on investments in Arlington Fund’s membership interests may or may not equal the imputed rate applied to the membership interests that are characterized as debt. In the consolidation, the Company eliminates 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.
	The following tables present the unconsolidated, stand alone balance sheet of Arlington Fund.

Commitments And Contingencies Disclosure [Abstract]	'
Financial Instruments with Off-Balance Sheet Risk	'
	Note 13. 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, standby letters of credit and interest rate mitigation products. The instruments involve, to varying degrees, elements of credit and interest rate 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 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.
	At December 31, 2013, the Company had $326.2 million of unused lines of credit. Of these unused lines of credit, unfunded commitments related to revolving credit facilities were $271.9 million and unfunded commitments related to delayed draw term loans were $49.0 million. $5.3 million of the unused revolving commitments are unavailable to the borrowers, which may be related to the borrowers’ inability to meet covenant obligations or other similar events.
	Revolving credit facilities allow the Company’s borrowers to draw up to a specified amount, subject to customary borrowing conditions. The unfunded revolving commitments of $271.9 million are further categorized as either contingent or unrestricted. Contingent commitments limit a borrower’s ability to access the revolver unless it meets an enumerated borrowing base covenant or other restrictions. At December 31, 2013, the Company categorized $197.7 million of the unfunded commitments related to revolving credit facilities as contingent. Unrestricted commitments represent commitments that are currently accessible, assuming the borrower is in compliance with certain customary loan terms and conditions. At December 31, 2013, the Company had $74.2 million of unfunded unrestricted revolving commitments.
	During the three months ended December 31, 2013, revolver usage averaged approximately 41%, which is in line with the average of 46% over the previous four quarters. Management’s experience indicates that borrowers typically do not seek to exercise their entire available line of credit at any point in time. During the three months ended December 31, 2013, revolving commitments increased $14.6 million.
	Delayed draw credit facilities allow the Company’s borrowers to draw predefined amounts of the approved loan commitment at contractually set times, subject to specific conditions, such as capital expenditures or acquisitions in corporate loans or for tenant improvements in commercial real estate loans. During the three months ended December 31, 2013, delayed draw credit facility commitments decreased $8.6 million.
	Standby letters of credit are conditional commitments issued by us to guarantee the performance by a borrower to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending credit to our borrowers.
	Interest rate risk mitigation products are offered to enable customers to meet their financing and risk management objectives. Derivative financial instruments consist predominantly of interest rate swaps, interest rate caps and floors. The interest rate risks to the Company of these customer derivatives is mitigated by entering into similar derivatives having offsetting terms with other counterparties.
	These interest rate risk mitigation products do not qualify for hedge accounting treatment. These interest rate swaps and caps contracts are recorded at fair value on the Company’s balance sheet in either “Other assets” or “Other liabilities.” Gains and losses on derivatives not designated as cash flow hedges, including any cash payments made or received are reported as gains or losses on derivatives in the consolidated statements of operations. The Company’s outstanding interest rate mitigation products had a fair value of $0 at December 31, 2013 and 2012.

As of December 31, 2013 and 2012, we had net deferred tax assets of $30.2 million and $42.5 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, 2013. 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 and tax rate, 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; and the impact on funding levels) on the Company. Based upon its assessment, management believes that a valuation allowance was not necessary as of December 31, 2013.
At December 31, 2013 and 2012, the Company did not have any significant unrecognized tax benefits and there have been no material changes. The Company does not expect any significant changes within the next 12 months.
The Company files U.S. federal and state income tax returns. As of December 31, 2013, the Company is subject to examination by the Internal Revenue Service and most state tax authorities for tax years after December 31, 2009. A few states remain subject to examination for the year ended December 31, 2009.

Fair Value	'

	Note 15. Fair Value
	ASC 820, Fair Value Measurements (“ASC 820”) establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:

		•		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.
	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
	The Company does not record loans at fair value on a recurring basis. However, from time to time, a loan is considered impaired and an allowance for loan losses may be established. If it is probable that payment of interest and principal on a loan will not be made in accordance with the contractual terms of the loan agreement, then it is considered impaired. Once a loan is identified as individually impaired, management measures the amount of impairment. The fair value of impaired loans is estimated using one of several methods, including collateral value, market value of similar debt, enterprise value, liquidation value and discounted cash flows. Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral equals or exceeds the recorded investments in such loans. Impaired loans where an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. When fair value of the collateral is based on an observable market price or a current appraised value, the Company records the impaired loan as level 3. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, the Company records the impaired loan as level 3.
	Loans held-for-sale
	Loans held-for-sale are not recorded at fair value on a recurring basis and are carried at the lower of cost or market value. Fair values for loans held-for-sale 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 prices are available in an active market, loans held-for-sale are classified as level 1. Level 1 loans include instruments where the fair value is based on a contracted selling price. Loans 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
	The Company does not record other real estate owned at fair value on a recurring basis. The fair value of other real estate owned is estimated using one of several methods, including collateral value, market value of similar properties, liquidation value and discounted cash flows. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price or inputs, the Company records the other real estate owned as level 3.
	Fair value of derivative instruments
	Derivatives are recorded at fair value on a recurring basis. Substantially all derivative instruments held or issued by the Company for risk management or customer-initiated activities are traded in over-the-counter markets where quoted market prices are not readily available. For those derivatives, the Company measures fair value using broker quotes or financial models that use primarily market observable inputs, such as yield curves and option volatilities, and include the value associated with the counterparty credit risk. The Company classifies derivative instruments held or issued for risk management or customer-initiated activities as level 2. Examples of level 2 derivatives are interest rate swaps and interest rate cap contracts.
	The Company also holds a portfolio of warrants for generally non-marketable equity securities, which are carried at $8.0 million as of December 31, 2013 and 2012. These warrants are primarily from non-public companies 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 following table presents recorded amounts of assets and liabilities measured at fair value on a recurring and nonrecurring basis as of December 31, 2013, by caption in the consolidated balance sheet and by ASC 820 valuation hierarchy (as described above).

Changes in level 3 recurring fair value measurements
The table below illustrates the change in balance sheet amounts during 2013 and 2012 (including the change in fair value), for financial instruments measured on a recurring basis and classified by the Company as level 3 in the valuation hierarchy. 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 2013 and 2012.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments:
Cash and cash equivalents and restricted cash: The carrying amounts approximate fair value because of the short maturity of these instruments.
Loans held-for-sale, net: The fair values are based on quoted prices, where available, cost, 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 does not incorporate the exit price concept of fair value and is based on significant unobservable inputs. The amount included in the above table excludes impaired collateral-dependent commercial real estate loans.
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.
Credit facilities: Due to the adjustable rate nature of the borrowings, the fair values of the credit facilities are estimated to be 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: The fair value was determined by applying prevailing term debt market interest rates to the Company’s current term debt structure.
Repurchase agreements: The fair value was determined by applying prevailing repurchase agreement market interest rates to the Company’s current repurchase agreement structure.
Other assets: Comprised of non-public investments which are initially valued at transaction price and subsequently adjusted when evidence is available to support such adjustments when appropriate. The estimated fair value was determined based on the Company’s valuation techniques, including discounting estimated cash flows and model-based valuations.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Consolidation	'
	Consolidation
	The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries (collectively, “NewStar”) and Arlington Fund (defined below), its variable interest entity (“VIE”) for which the Company is deemed to be the primary beneficiary and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). All significant intercompany transactions have been eliminated in consolidation.
	On April 8, 2013, the Company announced that it had 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 Arlington Fund, the Company retains full discretion over Arlington Fund’s investment decisions, subject to usual and customary limitations, and earns management fees as compensation for its services. Consolidation of the financial results of Arlington Fund with the Company’s results of operations and statements of financial position began in April 2013.
Use of Estimates	'
	Use of Estimates
	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. Estimates most susceptible to change in the near-term are the Company’s estimates of their allowance for credit losses, impairment of loans and recorded amounts of deferred income taxes.
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 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. If a decline in the fair value of a security below its amortized cost is judged by management to be other than temporary, the cost basis of the security is written down to fair value and the amount of the write-down is included in operations. 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 Company also recognizes an other than temporary impairment on an investment in debt security in an unrealized loss position if (i) the Company does not expect full recovery of its amortized cost based on the estimate of cash flows expected to be collected, (ii) the Company intends to sell the debt security, or (iii) it is more likely than not that the Company will be required to sell the debt security prior to recovery.
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. These loans are carried at the lower of aggregate cost, net of any deferred origination costs or fees, or market 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 changes in economic conditions, credit availability, industry 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 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 terms 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 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 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. There have been no material modifications to the allowance for credit losses methodology during 2013. 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 a judgmental amount which is governed by a score card system comprised of ten individually weighted 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. 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. 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.
	Impaired loans at December 31, 2013 were in Real Estate, Leveraged Finance, and Business Credit over a range of industries impacted by the then current economic environment including the following: Buildings and Commercial Real Estate, Broadcast and Entertainment, Nondurable Consumer Products, Energy and Chemical Services, Financial Services, Healthcare, Printing and Publishing, Restaurants, and Industrial and Other Business Services. For impaired Leveraged 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 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.
	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 changes in economic conditions, credit availability, industry 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.

Deferred Financing Costs	'
	Deferred Financing Costs
	Deferred financing costs represent fees and other direct incremental costs incurred in connection with borrowings. These amounts are amortized using the straight-line method into earnings as interest expense ratably over the contractual term of the facility.
Property and Equipment	'
	Property and Equipment
	Property and equipment are carried at cost and are depreciated or amortized on a straight-line basis over the following useful lives:


	Leasehold improvements	Shorter of estimated life or remaining lease term
	Computer equipment and software	3 years
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, 2013, 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 as fee income.
Asset Management Income	'
	Asset Management Income
	NewStar Financial, Inc. earns asset management income for investment management services performed for the NewStar Credit Opportunities Fund, Ltd. 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
	Effective January 1, 2006, the Company adopted ASC 718 (Share-Based Payment), which requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values on the grant date. The Company adopted ASC 718 using the prospective method.
	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 on Sale of Loans	'
	Gain 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 Method of Accounting	'
	Equity Method of Accounting
	As the result of a troubled debt restructuring, the Company may acquire a portion of the equity in the borrower. 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.
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, 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.
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. Other than temporary impairment charges are reclassified to earnings at the time of the charge.
