BlackRock Kelso Capital Corporation

Notes to Consolidated Financial Statements (Unaudited)

1. Organization

BlackRock Kelso Capital Corporation and subsidiaries (the “Company”) was organized as a Delaware corporation on April 13, 2005 and was initially funded on July 25, 2005. The Company has elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940 (the “1940 Act”). In addition, for tax purposes the Company has qualified and has elected to be treated as a regulated investment company (“RIC”) under the Internal Revenue Code of 1986 (the “Code”). The Company’s investment objective is to generate both current income and capital appreciation through debt and equity investments. The Company invests primarily in middle-market companies in the form of senior and junior secured and unsecured debt securities and loans, each of which may include an equity component, and by making direct preferred, common and other equity investments in such companies.

The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

Certain financial information that is normally included in annual financial statements, including certain financial statement footnotes, prepared in accordance with GAAP, is not required for interim reporting purposes and has been condensed or omitted herein. These consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes related thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012, which was filed with the Securities and Exchange Commission (“SEC”) on March 7, 2013.

2. Significant accounting policies

Basis of Presentation

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated financial statements and the reported amounts of income and expenses during the reported period. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ and such differences could be material.

The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries, which were established to hold certain investments of the Company. The Company owns 100% of each subsidiary and, as such, the subsidiaries are consolidated into the Company’s consolidated financial statements. The subsidiaries hold investments which are treated as pass through entities for tax purposes. By investing through these 100% owned subsidiaries, the Company is able to benefit from corporate tax treatment for these entities and thereby create a tax structure that is more advantageous with respect to the RIC status of the Company. Transactions between subsidiaries, to the extent they occur, are eliminated in consolidation.

Expenses are recorded on an accrual basis.

Investments

Security transactions are accounted for on the trade date unless there are substantial conditions to the purchase. Realized gains or losses are measured by the difference between the net proceeds from the repayment or sale and the amortized cost basis of the investment. Unrealized gains or losses primarily reflect the change in investment values, including the reversal of previously recorded unrealized gains or losses when gains or losses are realized. Realized gains or losses on the disposition of investments are calculated using the specific identification method.

Investments for which market quotations are readily available are valued at such market quotations unless they are deemed not to represent fair value. The Company obtains market quotations, when available, from an independent pricing service or one or more broker-dealers or market makers and utilizes the average of the range of bid and ask quotations. Debt and equity securities for which market quotations are not readily available or for which market quotations are deemed not to represent fair value are valued at fair value as determined in good faith by or under the direction of the Company’s Board of Directors.

Because the Company expects that there will not be a readily available market for substantially all of the investments in its portfolio, the Company expects to value substantially all of its portfolio investments at fair value as determined in good faith by or under the direction of the Board of Directors using a consistently applied valuation process in accordance with a documented valuation policy that has been reviewed and approved by the Board of Directors. Due to the inherent uncertainty and subjectivity of determining the fair value of investments that do not have a readily available market value, the fair value of the Company’s investments may differ significantly from the values that would have been used had a readily available market value existed for such investments and may differ materially from the values that the Company may ultimately realize.

In addition, changes in the market environment and other events may have differing impacts on the market quotations used to value some of the Company’s investments than on the fair values of the Company’s investments for which market quotations are not readily available. Market quotations may be deemed not to represent fair value in certain circumstances where BlackRock Kelso Capital Advisors LLC, the Company’s investment advisor (the “Advisor”), believes that facts and circumstances applicable to an issuer, a seller or purchaser or the market for a particular security cause current market quotations to not reflect the fair value of the security. Examples of these events could include cases where a security trades infrequently causing a quoted purchase or sale price to become stale, where there is a “forced” sale by a distressed seller, where market quotations vary substantially among market makers, or where there is a wide bid-ask spread or significant increase in the bid-ask spread.

With respect to the Company’s investments for which market quotations are not readily available or for which market quotations are deemed not to represent fair value, the Board of Directors has approved a multi-step valuation process applied each quarter, as described below:

(i) The quarterly valuation process begins with each portfolio company or investment being initially evaluated and rated by the investment professionals of the Advisor responsible for the portfolio investment;

(ii) The investment professionals provide recent portfolio company financial statements and other reporting materials to independent valuation firms engaged by the Board of Directors, such firms conduct independent appraisals each quarter and their preliminary valuation conclusions are documented and discussed with senior management of the Advisor;

(iii) The audit committee of the Board of Directors reviews the preliminary valuations prepared by the independent valuation firms; and

(iv) The Board of Directors discusses valuations and determines the fair value of each investment in the portfolio in good faith based on the input of the Advisor, the respective independent valuation firms and the audit committee.

Those investments for which market quotations are not readily available or for which market quotations are deemed not to represent fair value are valued utilizing a market approach, an income approach, or both approaches, as appropriate. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities (including a business). The income approach uses valuation techniques to convert future amounts (for example, cash flows or earnings) to a single present amount (discounted). The measurement is based on the value indicated by current market expectations about those future amounts. In following these approaches, the types of factors that the Company may take into account in determining the fair value of its investments include, as relevant and among other factors: available current

market data, including relevant and applicable market trading and transaction comparables, applicable market yields and multiples, security covenants, call protection provisions, information rights, the nature and realizable value of any collateral, the portfolio company’s ability to make payments, (e.g. non-performance risk), its earnings and discounted cash flows, the markets in which the portfolio company does business, comparisons of financial ratios of peer companies that are public, M&A comparables, the Company’s principal market (as the reporting entity) and enterprise values.

Until the end of the second calendar quarter following its acquisition, each unquoted investment in a new portfolio company generally is held at amortized cost, which the Advisor believes approximates fair value under the circumstances. As of that date, an independent valuation firm conducts an initial independent appraisal of the investment.

Accounting Standards Codification (“ASC”) 820-10, Fair Value Measurements and Disclosures (“ASC 820-10”), issued by the Financial Accounting Standards Board (“FASB”), defines fair value, establishes a framework for measuring fair value and requires disclosures about fair value measurements. See note 10 for further details.

Cash and Cash Equivalents

Cash equivalents include short-term liquid overnight investments.

Revenue recognition

Interest income is recorded on an accrual basis and includes amortization of premiums and accretion of discounts. Discounts and premiums to par value on securities purchased are accreted/amortized into interest income over the life of the respective security. Premiums and discounts are determined based on the cash flows expected to be received for a particular investment upon maturity.

Dividend income is recorded on the ex-dividend date and is adjusted to the extent that the Company expects to collect such amounts. For loans and securities with payment-in-kind (“PIK”) income, which represents contractual interest or dividends accrued and added to the principal balance and generally due at maturity, such income is accrued only to the extent that the Advisor believes that the PIK income is likely to be collected. To maintain the Company’s status as a RIC, this non-cash source of income must be paid out to stockholders in the form of dividends, even though the Company has not yet collected the cash.

Fee income, such as structuring fees, origination, closing, commitment and other upfront fees are generally non-recurring and are recognized as revenue when earned. In instances where the Company does not perform significant services in connection with the related investment, fees paid to the Company may be deferred and amortized over the estimated life of the investment. Upon the prepayment of a loan or debt security, any prepayment penalties and unamortized loan origination, structuring, closing, commitment and other upfront fees are recorded as income.

U.S. Federal income taxes

The Company has elected to be treated as a RIC under Subchapter M of the Code and operates in a manner so as to qualify for the tax treatment applicable to RICs.

In order to qualify for favorable tax treatment as a RIC, the Company is required to distribute annually to its stockholders at least 90% of its investment company taxable income, as defined by the Code. To avoid federal excise taxes, we must distribute annually at least 98% of our ordinary income and 98.2% of net capital gains from the current year and any undistributed ordinary income and net capital gains from the preceding years. The Company, at its discretion, may carry forward taxable income in excess of calendar year distributions and pay a 4% excise tax on this income. If the Company chooses to do so, all other things being equal, this would increase expenses and reduce the amount available to be distributed to stockholders. The Company will accrue excise tax on estimated undistributed taxable income as required.

Dividends from net investment income and distributions from net realized capital gains are determined in accordance with U.S. federal income tax regulations, which may differ from those amounts determined in accordance with GAAP. These book/tax differences are either temporary or permanent in nature. To the extent these differences are permanent, they are charged or credited to paid-in-capital or accumulated net realized gain (loss), as appropriate, in the period that the differences arise. Temporary and permanent differences are primarily attributable to differences in the tax treatment of certain loans and the tax characterization of income and non-deductible expenses. These differences are generally determined in conjunction with the preparation of the Company’s annual RIC tax return.

Book and tax basis differences relating to stockholder dividends and distributions and other permanent book and tax differences are reclassified among the Company’s capital accounts. In addition, the character of income and gains to be distributed is determined in accordance with income tax regulations that may differ from GAAP.

The Company may pay distributions in excess of its taxable net investment income. This excess would be a tax-free return of capital in the period and reduce the shareholder’s tax basis in its shares. The cumulative amount is disclosed on the Consolidated Statements of Assets and Liabilities as distributions in excess of taxable net investment income. Cumulative distributions in excess of taxable net investment income are $28,556,684 and $22,291,022 as of March 31, 2013 and December 31, 2012, respectively.

Dividends to Common Stockholders

Dividends and distributions to common stockholders are recorded on the ex-dividend date. The amount to be paid out as a dividend is determined by the Board of Directors. Net realized capital gains, if any, generally are distributed at least annually, although the Company may decide to retain such capital gains for investment.

The Company has adopted a dividend reinvestment plan that provides for reinvestment of distributions on behalf of stockholders, unless a stockholder elects to receive cash. As a result, if the Board of Directors authorizes, and the Company declares, a cash dividend, then stockholders who have not “opted out” of the dividend reinvestment plan will have their cash dividends automatically reinvested in additional shares of Common Stock, rather than receiving the cash dividends.

Foreign Currency

Foreign currency amounts are translated into United States dollars on the following basis:

(i)

market value of investment securities, other assets and liabilities—at the spot exchange rate on the last business day of the period; and

(ii)

purchases and sales of investment securities, income and expenses—at the rates of exchange prevailing on the respective dates of such transactions, income or expenses.

Although net assets and fair values are presented based on the applicable foreign exchange rates described above, the Company does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in fair values of investments held. Such fluctuations are included with the net realized and unrealized gain or loss from investments.

Investments denominated in foreign currencies and foreign currency transactions may involve certain considerations and risks not typically associated with those of domestic origin, including unanticipated movements in the value of the foreign currency relative to the U.S. dollar.

Debt Issuance Costs

Debt issuance costs are amortized over the term of the related debt using the straight line method.

Equity Offering Expenses

The Company records registration expenses related to its shelf registration statement and related SEC filings as prepaid assets. These expenses are charged as a reduction of capital upon utilization, in accordance with ASC 946, Financial Services—Investment Companies.

Non-Accrual Loans

Loans or debt securities are placed on non-accrual status, as a general matter, when principal or interest payments are past due 30 days or more or when there is reasonable doubt that principal or interest will be collected. Accrued interest generally is reversed when a loan or debt security is placed on non-accrual status. Interest payments received on non-accrual loans or debt securities may be recognized as income or applied to principal depending upon management’s judgment. Non-accrual loans and debt securities are restored to accrual status when past due principal and interest is paid and, in management’s judgment, are likely to remain current. The Company may make exceptions to this treatment if the loan has sufficient collateral value and is in the process of collection.

Recently Issued Accounting Pronouncements

In December 2011, the FASB issued ASU 2011-11, Disclosures about Offsetting Assets and Liabilities (“ASU 2011-11”). These disclosure requirements are intended to help investors and other financial statement users to better assess the effect or potential effect of offsetting arrangements on an entity’s financial position. They also improve transparency in the reporting of how companies mitigate credit risk, including disclosure of related collateral pledged or received. In addition, ASU 2011-11 facilitates comparison between those entities that prepare their financial statements on the basis of U.S. GAAP and those entities that prepare their financial statements on the basis of IFRS. ASU 2011-11 requires entities to disclose both gross and net information about both instruments and transactions eligible for offset in the financial position; and to disclose instruments and transactions subject to an agreement similar to a master netting agreement. ASU 2011-11 is effective for fiscal years beginning on or after January 1, 2013, and interim periods within those annual periods. The adoption of ASU 2011-11 did not have a material impact on the Company’s disclosures, which have been reflected in the notes to these consolidated financial statements.

In January 2013, the FASB issued ASU 2013-01, Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities (“ASU 2013-01”). This update clarifies that the scope of ASU 2011-11 applies to derivatives accounted for in accordance with Topic 815. This update is effective for the Company for the year ending December 31, 2013, and did not have a material effect on the Company’s consolidated financial statements.

3. Agreements and related party transactions

Base Management Fee

The Company has entered into an Investment Management Agreement (the “Management Agreement”) with the Advisor, under which the Advisor, subject to the overall supervision of the Company’s Board of Directors, manages the day-to-day operations of, and provides investment advisory services to, the Company. For providing these services, the Advisor receives a base management fee (the “Management Fee”) from the Company quarterly in arrears at an annual rate of 2.0% of the Company’s total assets, including any assets acquired with the proceeds of leverage.

For the three months ended March 31, 2013 and 2012, the Advisor earned $5,349,956 and $5,390,448, respectively, in in base management fees under the Management Agreement.

Incentive Management Fee

The Management Agreement provides that the Advisor or its affiliates may be entitled to an incentive management fee (the “Incentive Fee”) under certain circumstances. The determination of the Incentive Fee, as described in more detail below, will result in the Advisor or its affiliates receiving no Incentive Fee payments if returns to Company stockholders do not meet an 8.0% annualized rate of return during the applicable fee measurement period and will result in the Advisor or its affiliates receiving less than the full amount of the Incentive Fee percentage until returns to stockholders exceed an approximate 13.3% annualized rate of return during such period. Annualized rate of return in this context is computed by reference to the Company’s net asset value and does not take into account changes in the market price of the Company’s common stock.

The Advisor will be entitled to receive the Incentive Fee if the Company’s performance exceeds a “hurdle rate” during different measurement periods: trailing four quarters’ periods (which applies only to the portion of the Incentive Fee based on income) and annual periods (which applies only to the portion of the Incentive Fee based on capital gains). The “trailing four quarters’ periods” for purposes of determining the income portion of the Incentive Fee payable for the three months ended March 31, 2013 and 2012 was determined by reference to the four quarter periods ended on March 31, 2013 and 2012, respectively. The term “annual period” means the period beginning on July 1 of each calendar year and ending on June 30 of the next calendar year.

The hurdle rate for each measurement period is 2.0% multiplied by the Company’s net asset values at the beginning of each calendar quarter during the measurement period, calculated after giving effect to any distributions that occurred during the measurement period. A portion of the Incentive Fee is based on the Company’s income and a portion is based on capital gains. Each portion of the Incentive Fee is described below.

Quarterly Incentive Fee Based on Income. For each trailing four quarters’ period, the Company pays the Advisor an Incentive Fee based on the amount by which (A) aggregate distributions and amounts distributable out of taxable net income (excluding any capital gain and loss) during the period less the amount, if any, by which net unrealized capital depreciation exceeds net realized capital gains during the period exceeds (B) the hurdle rate for the period. The amount of the excess of (A) over (B) described in this paragraph for each period is referred to as the excess income amount.

The portion of the Incentive Fee based on income for each period will equal 50% of the period’s excess income amount, until the cumulative Incentive Fee payments for the period equal 20% of the period’s income amount distributed or distributable to stockholders as described in clause (A) of the preceding paragraph. Thereafter, the portion of the Incentive Fee based on income for the period will equal 20% of the period’s remaining excess income amount.

For the three months ended March 31, 2013 and 2012, the Advisor earned $1,543,384 and $2,213,859 respectively, in Incentive Fees based on income from the Company.

Annual Incentive Fee Based on Capital Gains. The portion of the Incentive Fee based on capital gains is calculated and paid on an annual basis beginning on July 1, 2007, the first day of the calendar quarter in which the Public Market Event occurred and each annual period thereafter, ending on June 30 of the next calendar year. For each annual period, the Company pays the Advisor an Incentive Fee based on the amount by which (A) net realized capital gains, if any, to the extent they exceed gross unrealized capital depreciation, if any, occurring during the period exceeds (B) the amount, if any, by which the period’s hurdle rate exceeds the amount of income used in the determination of the Incentive Fee based on income for the period. The amount of the excess of (A) over (B) described in this paragraph is referred to as the excess gain amount.

The portion of the Incentive Fee based on capital gains for each period will equal 50% of the period’s excess gain amount, until such payments equal 20% of the period’s capital gain amount distributed or distributable to stockholders. Thereafter, the portion of the Incentive Fee based on capital gains for the period equals an amount such that the portion of the Incentive Fee payments to the Advisor based on capital gains for

the period equals 20% of the period’s remaining excess gain amount. The result of this formula is that, if the portion of the Incentive Fee based on income for the period exceeds the period’s hurdle, then the portion of the Incentive Fee based on capital gains will be capped at 20% of the capital gain amount.

In calculating whether the portion of the Incentive Fee based on capital gains is payable with respect to any period, the Company accounts for its assets on a security-by-security basis. In addition, the Company uses the “period-to-period” method pursuant to which the portion of the Incentive Fee based on capital gains for any period is based on realized capital gains for the period reduced by realized capital losses and gross unrealized capital depreciation for the period. Based on current interpretations of Section 205(b)(3) of the Investment Advisers Act of 1940 by the SEC and its staff, the calculation of unrealized depreciation for each portfolio security over a period is based on the fair value of the security at the end of the period compared to the fair value at the beginning of the period. Incentive Fees earned in any of the periods described above are not subject to modification or repayment based upon performance in a subsequent period.

We are required under GAAP to accrue a hypothetical capital gains Incentive Fee based upon net realized capital gains and unrealized capital appreciation and depreciation on investments held at the end of each period. The accrual of this hypothetical capital gains incentive fee assumes all unrealized capital appreciation and depreciation is realized in order to reflect a hypothetical capital gains incentive fee that would be payable at each measurement date. If such amount is positive at the end of the period, then we record a capital gains incentive fee equal to 20% of such amount, less the amount of capital gains related incentive fees already accrued in prior periods. If the resulting amount is negative, the accrual for GAAP in a given period may result in an additional expense. There can be no assurance that such unrealized capital appreciation will be realized in the future. However, it should be noted that a fee so calculated and accrued would not be payable under the Investment Advisers Act of 1940 or the Management Agreement. Amounts actually paid will be consistent with the Advisers Act which specifically excludes consideration of unrealized capital appreciation.

The capital gains fee due the Advisor as calculated under the Management Agreement as described above, for the three months ended March 31, 2013 and 2012 were zero. In accordance with GAAP the hypothetical incentive fee for the three months ended March 31, 2013 and 2012, resulted in a capital gains incentive fee of $3,720,726 and zero, respectively. The total cumulative balance at March 31, 2013 and 2012 was $9,215,461 and zero, respectively.

Advisor Reimbursements

The Management Agreement provides that the Company will reimburse the Advisor for costs and expenses incurred by the Advisor for office space rental, office equipment and utilities allocable to the Advisor under the Management Agreement, as well as any costs and expenses incurred by the Advisor relating to any non-investment advisory, administrative or operating services provided by the Advisor to the Company. For the three months ended March 31, 2013 and 2012, the Company incurred $558,098 and $363,685, respectively, for such investment advisor expenses under the Management Agreement.

From time to time, the Advisor may pay amounts owed by the Company to third party providers of goods or services. The Company will subsequently reimburse the Advisor for such amounts paid on its behalf. Reimbursements to the Advisor for the three months ended March 31, 2013 and 2012 were $1,004,665 and $481,022, respectively.

No person who is an officer, director or employee of the Advisor and who serves as a director of the Company receives any compensation from the Company for such services. Directors who are not affiliated with the Advisor receive compensation for their services and reimbursement of expenses incurred to attend meetings.

Administration

The Company also has entered into an administration agreement with BlackRock Financial Management, Inc. (the “Administrator”) under which the Administrator provides certain administrative services to the

Company. For providing these services, facilities and personnel, the Company reimburses the Administrator for the Company’s allocable portion of overhead and other expenses incurred by the Administrator in performing its obligations under the administration agreement, including rent and the Company’s allocable portion of the cost of certain of the Company’s officers and their respective staffs. For the three months ended March 31, 2013 and 2012, the Company incurred $201,283 and $30,706, respectively, for administrative services expenses payable to the Administrator under the administration agreement.

Advisor Stock Transactions

In 2007, the Company’s Board of Directors authorized the purchase by the Advisor from time to time in the open market of an indeterminate number of shares of the Company’s common stock, in the Advisor’s discretion, subject to compliance with the Company’s and the Advisor’s applicable policies and requirements of law. There were no such purchases during the three months ended March 31, 2013 and 2012.

In March 2011, the Company’s Board of Directors authorized the purchase in a private placement of up to 1,000,000 shares of the Company’s common stock, by the Advisor in its discretion, subject to compliance with the Company’s and the Advisor’s applicable policies and requirements of law. There were no private placement purchases for the three months ended March 31, 2013 and 2012.

At March 31, 2013 and December 31, 2012, the Advisor owned and had the right to vote approximately 54,000 and 94,000 shares, respectively, of the Company’s common stock, representing less than 1.0% of the total shares outstanding. On such dates, under compensation arrangements for its officers and employees the Advisor owned of record but did not have the right to vote an additional 125,000 and 261,000 shares, respectively, of the Company’s common stock. At March 31, 2013 and December 31, 2012, other entities affiliated with the Administrator beneficially owned approximately 5,015,000 and 6,019,000 shares, respectively, of the Company’s common stock, representing approximately 6.8% and 8.2% of the total shares outstanding. An entity affiliated with the Administrator has ownership and financial interests in the Advisor.

4. Earnings per share

The following information sets forth the computation of basic and diluted net increase in net assets from operations per share (earnings per share) for the three months ended March 31, 2013 and 2012.


	Three months ended March 31, 2013		Three months ended March 31, 2012
Earnings per share – basic:
Net increase in net assets resulting from operations	$	29,797,139	$	20,298,244
Weighted average shares outstanding - basic		73,957,696		73,417,624
Earnings per share – basic:	$	0.40	$	0.28
Earnings per share – diluted:
Net increase in net assets resulting from operations, before adjustments	$	29,797,139	$	20,298,244
Adjustments for interest on unsecured convertible senior notes		720,347		—

Market and Credit Risk

In the normal course of business, the Company invests in securities and enters into transactions where risks exist due to fluctuations in the market (market risk) or failure of the issuer of a security to meet all its obligations (issuer credit risk). The value of securities held by the Company may decline in response to certain events, including those directly involving the issuers whose securities are owned by the Company; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency and interest rate and price fluctuations. Similar to issuer credit risk, the Company may be exposed to counterparty credit risk, or the risk that an entity with which the Company has unsettled or open transactions may fail to or be unable to perform on its commitments. The Company manages counterparty risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose the Company to market, issuer and counterparty credit risks, consist principally of investments in portfolio companies. The extent of the Company’s exposure to market, issuer and counterparty credit risks with respect to these financial assets is generally approximated by their value recorded in the consolidated statements of assets and liabilities. The Company is also exposed to credit risk related to maintaining all of its cash at a major financial institution.

The Company has investments in lower rated and comparable quality unrated senior and junior secured, unsecured and subordinated debt securities and loans, which are subject to a greater degree of credit risk than

more highly rated investments. The risk of loss due to default by the issuer is significantly greater for holders of such securities and loans, particularly in cases where the investment is unsecured or subordinated to other creditors of the issuer.

6. Derivatives

Foreign Currency

The Company may enter into forward foreign currency contracts from time to time to facilitate settlement of purchases and sales of investments denominated in foreign currencies or to help mitigate the impact that an adverse change in foreign exchange rates would have on the value of the Company’s investments denominated in foreign currencies. A forward foreign currency contract is a commitment to purchase or sell a foreign currency at a future date (usually the security transaction settlement date) at a negotiated forward rate. These contracts are marked-to-market by recognizing the difference between the contract exchange rate and the current market rate as unrealized appreciation or depreciation. Realized gains or losses are recognized when contracts are settled. The Company’s forward foreign currency contracts generally have terms of approximately three months. The volume of open contracts at the end of each reporting period is reflective of the typical volume of transactions during each calendar quarter. Risks may arise as a result of the potential inability of the counterparties to meet the terms of their contracts. The Company attempts to limit this risk by dealing with only creditworthy counterparties.

At March 31, 2013, details of open forward foreign currency contracts were as follows:


Foreign Currency	Settlement Date		Amount and Transaction		US$ Value at Settlement Date			US$ Value at March 31, 2013			Unrealized Appreciation (Depreciation)
Canadian dollar		April 17, 2013		20,683,000 Sold		$ 20,964,129			$ 20,340,748			$ 623,381
Canadian dollar		April 17, 2013		784 Purchased		(794	)		(771	)		(23	)
Canadian dollar		April 17, 2013		310,777 Purchased		(311,461	)		(305,634	)		(5,827	)

Total						$ 20,651,874			$ 20,034,343			$ 617,531

At December 31, 2012, details of open forward foreign currency contracts were as follows:


Foreign Currency	Settlement Date		Amount and Transaction		US$ Value at Settlement Date			US$ Value at December 31, 2012		Unrealized Appreciation (Depreciation)
Canadian dollar		January 16, 2013		21,880,000 Sold		$ 22,373,103			$ 22,002,621		$ 370,482
Canadian dollar		January 16, 2013		324,397 Purchased		(324,962	)		(326,215)		1,253
Canadian dollar		January 16, 2013		334,652 Purchased		(338,845	)		(336,527)		(2,318	)

Total						$ 21,709,296			$ 21,339,879		$ 369,417

All realized and unrealized gains and losses on forward foreign currency contracts are included in earnings (changes in net assets) and are reported as separate line items within the Company’s consolidated statements of operations. Unrealized gains and losses on forward foreign currency contracts are also reported as separate line items within the Company’s consolidated statements of assets and liabilities.

The Company may enter into other derivative instruments and incur other exposures with other counterparties in the future. The derivative instruments held as of March 31, 2013 and December 31, 2012 reflect the volume of derivative activity throughout the periods presented.

Warrants

The Company holds warrants and options in certain portfolio companies in an effort to achieve additional investment return. In purchasing warrants and options, the Company bears the risk of an unfavorable change in the value of the underlying equity interest. The aggregate fair value of warrants and options as of March 31, 2013 and December 31, 2012 represents 2.6% and 2.4%, respectively, of the Company’s net assets.

7. Debt

On March 13, 2013, the Company entered into an Amended and Restated Senior Secured Revolving Credit Facility (“Credit Facility”) which has an initial aggregate principal amount of up to $350,000,000 and canceled the prior credit facility and the related term loan that were outstanding at December 31, 2012. The Credit Facility has a stated maturity date of March 13, 2017. The interest rate applicable to borrowings thereunder is generally LIBOR plus an applicable margin of 2.50%. The Credit Facility’s commitment may increase in size, under certain circumstances, up to a total of $750,000,000.

On February 19, 2013, the Company closed a private offering of $100,000,000 in aggregate principal amount of 5.50% unsecured convertible senior notes due 2018 (the “Convertible Notes”). The initial purchasers of the Convertible Notes fully exercised their overallotment option and purchased an additional $15,000,000 in aggregate principal amount of the Convertible Notes. The closing of the overallotment option took place on March 4, 2013. With the exercise of the overallotment option, a total of $115,000,000 in aggregate principal amount of the Convertible Notes have been sold. Net proceeds to the Company from the offering, including the exercise of the overallotment option, were approximately $111,300,000. The Convertible Notes were only offered to qualified institutional buyers as defined in the Securities Act of 1933, as amended (the “Securities Act”) pursuant to Rule 144A under the Securities Act.

The Convertible Notes are unsecured and bear interest at a rate of 5.50% per year, payable semi-annually in arrears. In certain circumstances and during certain periods, the Convertible Notes are convertible into cash, shares of BlackRock Kelso Capital’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election, at an initial conversion rate of 86.0585 shares of common stock per $1,000 principal amount of the Convertible Notes, which is equivalent to an initial conversion price of approximately $11.62 per share of the Company’s common stock, subject to defined anti-dilution adjustments. The Company does not have the right to redeem the Convertible Notes prior to maturity. The Convertible Notes mature on February 15, 2018, unless repurchased or converted in accordance with their terms prior to such date.

On January 18, 2011, the Company closed a private placement issuance of $158,000,000 in aggregate principal amount of five-year, senior secured notes with a fixed interest rate of 6.50% and a maturity date of January 18, 2016 and $17,000,000 million in aggregate principal amount of seven-year, senior secured notes with a fixed interest rate of 6.60% and a maturity date of January 18, 2018 (collectively, the “Senior Secured Notes”). The Senior Secured Notes were sold to certain institutional accredited investors pursuant to an exemption from registration under the Securities Act of 1933, as amended. Interest on the Senior Secured Notes is due semi-annually on January 18 and July 18, commencing on July 18, 2011.

At March 31, 2013, the Company had $17,000,000 drawn on the Credit Facility versus $171,850,000 at December 31, 2012. Subject to compliance with applicable covenants and borrowing base limitations, the remaining amount available under the Credit Facility was $333,000,000 at March 31, 2013.

The Company’s average outstanding debt balance during the three months ended March 31, 2013 and 2012 was $329,905,368 and $354,976,923, respectively. The maximum amounts borrowed during the three months ended March 31, 2013 and 2012 were $475,646,005 and $378,900,000, respectively.

The weighted average annual interest cost for the three months ended March 31, 2013 and 2012 was 5.45% and 5.03%, respectively, exclusive of commitment fees and of other prepaid expenses related to establishing the

Credit Facility, the Senior Secured Notes and the Convertible Notes. With respect to any unused portion of the commitments under the Credit Facility, the Company incurs an annual commitment fee of 0.375% on the Credit Facility outstanding at March 31, 2013 and 0.50% on the Credit Facility outstanding at March 31, 2012. Commitment fees incurred for the three months ended March 31, 2013 and 2012 were $306,015 and $252,238, respectively.

At March 31, 2013, the Company was in compliance with all covenants required under the Credit Facility, the Convertible Notes and the Senior Secured Notes.

8. Capital stock

In 2008, the Company’s Board of Directors approved a share repurchase plan under which the Company may repurchase up to 2.5 percent of its outstanding shares of common stock from time to time in open market or privately negotiated transactions. In 2009, the Board of Directors approved an extension and increase to the plan which authorized the Company to repurchase up to an additional 2.5 percent of its outstanding shares of common stock. In May 2012, the repurchase plan was further extended through the earlier of June 30, 2013 or until the approved number of shares has been repurchased. During the three months ended March 31, 2013 and 2012 the Company purchased zero shares of its common stock on the open market. Since inception of the repurchase plan through March 31, 2013, the Company has purchased 1,425,507 shares of its common stock on the open market for $9,476,676, including brokerage commissions. At March 31, 2013, the total number of remaining shares authorized for repurchase was 1,331,143. The Company currently holds the shares it repurchased in treasury.

9. Guarantees and commitments

In the normal course of business, the Company may enter into guarantees on behalf of portfolio companies. Under these arrangements, the Company would be required to make payments to third parties if the portfolio companies were to default on their related payment obligations. The Company has no such guarantees outstanding at March 31, 2013 and 2012.

In the normal course of business, the Company enters into contractual agreements that provide general indemnifications against losses, costs, claims and liabilities arising from the performance of individual obligations under such agreements. The Company has had no prior claims or payments pursuant to such agreements. The Company’s individual maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Company that have not yet occurred. However, based on management’s experience, the Company expects the risk of loss to be remote.

From time to time, the Company may be a party to certain legal proceedings incidental to the normal course of its business, including the enforcement of the Company’s rights under contracts with its portfolio companies. While the Company cannot predict the outcome of these legal proceedings with certainty, it does not expect that these proceedings will have a material effect on its consolidated financial statements.

10. Fair value of financial instruments

Fair Value Measurements and Disclosure

ASC 820-10 defines fair value, establishes a framework for measuring fair value and requires disclosures about fair value measurements. ASC 820-10 defines fair value as the price that the Company would receive upon selling an investment or pay to transfer a liability in an orderly transaction to a market participant in the principal or most advantageous market for the investment. ASC 820-10 emphasizes that valuation techniques maximize the use of observable market inputs and minimize the use of unobservable inputs. Inputs refer broadly to the assumptions that market participants would use in pricing an asset or liability, including assumptions about risk. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing an asset or liability developed based on market data obtained from sources

independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the assumptions market participants would use in pricing an asset or liability developed based on the best information available in the circumstances.

Level 1 – Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.

Level 2 – Valuations based on unadjusted quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

Level 3 – Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The inputs into the determination of fair value may require significant management judgment or estimation.

Transfers between levels, if any, represent the value as of the beginning of the period of any investment where a change in the pricing level occurred from the beginning to the end of the period.

The Company’s valuation policy and fair value disclosures are consistent with ASC 820-10. The Company evaluates the source of inputs, including any markets in which its investments are trading, in determining fair value and categorizes each investment within the fair value hierarchy pursuant to ASC 820-10.

Under the 1940 Act, the Company is required to separately identify non-controlled investments where it owns 5% or more of a portfolio company’s outstanding voting securities as investments in “affiliated” companies. In addition, under the 1940 Act, the Company is required to separately identify investments where it owns more than 25% of a portfolio company’s outstanding voting securities as investments in “controlled” companies. Detailed information with respect to the Company’s non-controlled non-affiliated, non-controlled affiliated and controlled investments is contained in the accompanying consolidated schedules of investments and other consolidated financial statements. The information in the tables below is presented on an aggregate portfolio basis, without segregating the non-controlled non-affiliated, non-controlled affiliated and controlled investment categories.

The carrying values of the Company’s financial instruments approximate fair value. The carrying values of receivables, other assets, accounts payable and accrued expenses approximate fair value due to their short maturities. The fair value of the Company’s Credit Facility, Convertible Notes and Senior Secured Notes is derived by taking the average of the high and low quotes as obtained from a broker. The fair value of the Credit Facility and Senior Secured Notes would be classified as Level 2 with respect to the fair value hierarchy.

The carrying and fair values of the Company’s Credit Facility payable were $17,000,000 and $16,660,000 at March 31, 2013 and $171,850,000 and $168,413,000 at December 31, 2012, respectively. The carrying and fair values of the Company’s Senior Secured Notes were $175,000,000 and $187,280,000 at March 31, 2013 and $175,000,000 and $189,507,410 at December 31, 2012, respectively. The carrying and fair values of the Company’s Convertible Notes were $113,796,005 and $113,227,025 at March 31, 2013. The carrying and fair values of the Company’s total debt outstanding were therefore $305,796,005 and $317,167,025 at March 31, 2013 and $346,850,000 and $357,920,410 at December 31, 2012, respectively.

The following tables summarize the fair values of the Company’s investments, forward foreign currency contracts and cash and cash equivalents based on the inputs used at March 31, 2013 and December 31, 2012 in determining such fair values:

In determining the fair values of the Company’s forward foreign currency contracts at March 31, 2013 and at December 31, 2012, the Company used unadjusted indicative price quotations for similar assets (Level 2).

The valuation techniques used at March 31, 2013 and December 31, 2012 in determining the fair values of the Company’s investments for which significant unobservable inputs were used were the market approach, income approach or both using third party valuation firms or broker quotes for identical or similar assets. The total fair market value using the market or income approach or using third party valuation firms was $1,022,401,297 and $1,061,396,764 as of March 31, 2013 and December 31, 2012, respectively. The remaining balance was determined using broker quotes for identical or similar assets.

The following is a reconciliation for the three months ended March 31, 2013 of investments for which Level 3 inputs were used in determining fair value:

There were no transfers between Levels during the three months ended March 31, 2013 and 2012. All realized and unrealized gains and losses are included in earnings (changes in net assets) and are reported as separate line items within the Company’s consolidated statements of operations.

The significant unobservable inputs used in the market approach of fair value measurement of the Company’s investments are the market multiples of earnings before income tax, depreciation and amortization (“EBITDA”) of the comparable guideline public companies. The independent valuation firms select a population of public companies for each investment with similar operations and attributes of the subject company. Using these guideline public companies’ data, a range of multiples of enterprise value to EBITDA is calculated. The independent valuation firms select percentages from the range of multiples for purposes of determining the subject company’s estimated enterprise value based on said multiple and generally the latest twelve months EBITDA of the subject company (or other meaningful measure). Significant increases or decreases in the multiple will result in an increase or decrease in enterprise value, resulting in an increase or decrease in the fair value estimate of the investment.

The significant unobservable input used in the income approach of fair value measurement of the Company’s investments is the discount rate or market yield used to discount the estimated future cash flows expected to be received from the underlying investment, which include both future principal and interest payments. Significant increases or decreases in the discount rate would result in an decrease or increase in the fair value measurement. Included in the consideration and selection of discount rates are the following factors: risk of default, rating of the investment and comparable company investments, and call provisions.

The ranges of significant unobservable inputs used in the fair value measurement of the Company’s Level 3 investments as of March 31, 2013 were as follows:

EBITDA Multiples:


		Cost	Fair Value	Low High	Weighted Average

Overview

We were incorporated in Delaware on April 13, 2005 and were initially funded on July 25, 2005. Our investment objective is to provide a combination of current income and capital appreciation. We intend to invest primarily in debt and equity securities of private and certain public U.S. middle-market companies.

We are externally managed and have elected to be regulated as a BDC under the 1940 Act. As a BDC, we are required to comply with certain regulatory requirements. For instance, we generally have to invest at least 70% of our total assets in “qualifying assets,” including securities of private or thinly traded public U.S. companies, cash, cash equivalents, U.S. Government securities and high-quality debt investments that mature in one year or less.

Investments

Our level of investment activity can and does vary substantially from period to period depending on many factors, including the amount of debt and equity capital available to middle-market companies, the level of merger and acquisition activity, the general economic environment and the competitive environment for the types of investments we make.

As a BDC, we must not acquire any assets other than “qualifying assets” specified in the 1940 Act unless, at the time the acquisition is made, at least 70% of our total assets are qualifying assets (with certain limited exceptions). Qualifying assets include investments in “eligible portfolio companies.” Under the relevant SEC rules, the term “eligible portfolio company” includes all private companies, companies whose securities are not listed on a national securities exchange, and certain public companies that have listed their securities on a national securities exchange and have a market capitalization of less than $250 million. These rules also permit us to include as qualifying assets certain follow-on investments in companies that were eligible portfolio companies at the time of initial investment but that no longer meet the definition.

Revenues

We generate revenues primarily in the form of interest on the debt we hold, dividends on our equity interests and capital gains on the sale of warrants and other debt or equity interests that we acquire in portfolio companies. Our investments in fixed income instruments generally have an expected maturity of three to ten years, although we have no lower or upper constraint on maturity, and typically bear interest at a fixed or floating rate. Interest on our debt securities is generally payable quarterly or semi-annually. In some cases, our debt instruments and preferred stock investments may defer payments of cash interest or dividends or pay interest or dividends in-kind. Any outstanding principal amount of our debt securities and any accrued but unpaid interest will generally become due at the maturity date. In addition, we may generate revenue in the form of prepayment fees, commitment, origination, capital structuring or due diligence fees, fees for providing significant managerial assistance and consulting fees.

Expenses

Our primary operating expenses include the payment of a base management fee and, depending on our operating results, an incentive management fee, expenses reimbursable under the management agreement, administration fees and the allocable portion of overhead under the administration agreement. The base management fee and incentive management fee compensate the Advisor for work in identifying, evaluating, negotiating, closing and monitoring our investments. Our management agreement with the Advisor provides that we will reimburse the Advisor for costs and expenses incurred by the Advisor for office space rental, office equipment and utilities allocable to the Advisor under the management agreement, as well as any costs and expenses incurred by the Advisor relating to any non-investment advisory, administrative or operating services provided by the Advisor to us. We bear all other costs and expenses of our operations and transactions.

Critical accounting policies

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the

reported amounts of assets, liabilities, revenues and expenses. Changes in the economic environment, financial markets and any other parameters used in determining such estimates could cause actual results to differ.

Management considers the following critical accounting policies important to understanding the consolidated financial statements. In addition to the discussion below, our critical accounting policies are further described in the notes to the consolidated financial statements. See Note 2 to the consolidated financial statements for a description of significant accounting policies and of recently issued accounting pronouncements.

Financial and operating highlights

At March 31, 2013:

Investment Portfolio: $1,023.7 million

Net Assets: $700.4 million

Indebtedness (borrowings under Credit Facility, Convertible Notes and

Senior Secured Notes): $305.8 million

Net Asset Value per share: $9.47

Portfolio Activity for the Three Months Ended March 31, 2013:

Cost of investments during period: $46.0 million

Sales, repayments and other exits during period: $104.2 million

Number of portfolio companies at end of period: 44

Operating Results for the Three Months Ended March 31, 2013:

Net investment income per share: $0.18

Dividends declared per share: $0.26

Earnings per share: $0.40

Net investment income: $13.0 million

Net realized and unrealized gains: $16.8 million

Net increase in net assets from operations: $29.8 million

Net investment income per share, as adjusted¹: $0.22

Earnings per share, as adjusted¹: $0.45

Net investment income, as adjusted¹: $16.1 million

As Adjusted¹: Amounts are adjusted to remove the incentive management fee expense based on Gains, as required by GAAP, and to include only the incremental incentive management fee expense based on Income. The incremental incentive management fee is based on the formula the Company utilizes for each trailing four-fiscal quarter period, with the formula applied to the current quarter’s incremental earnings, and without any reduction for incentive management fees paid during the prior three quarters. Amounts reflect the Company’s ongoing operating results and are the most effective indicator of the Company’s financial performance over time.

Portfolio and investment activity

We invested $46.0 million during the three months ended March 31, 2013.

The weighted average yields on our senior secured loans and other debt securities at fair value were 12.1% and 13.7%, respectively, at March 31, 2013, versus 11.9% and 13.6%, at December 31, 2012. The weighted average yield of the debt and income producing equity securities in our portfolio at their current cost basis was 12.4% at March 31, 2013 and 12.2% at December 31, 2012. The weighted average yields on our senior secured loans and other debt securities at their current cost basis were 11.5% and 13.6%, respectively, at March 31, 2013, versus 11.4% and 13.5%, at December 31, 2012. Yields exclude common equity investments, preferred equity investments with no stated dividend rate, short-term investments, and cash and cash equivalents.

At March 31, 2013, 49.6% of our debt investments bore interest based on floating rates, such as LIBOR, the Federal Funds Rate or the Prime Rate, and 50.4% bore interest at fixed rates. The percentage of our total debt investments that bore floating rate interest based on an interest rate floor was 47.6% at March 31, 2013. At December 31, 2012, 45.0% of our debt investments bore interest based on floating rates, such as LIBOR, the Federal Funds Rate or the Prime Rate, and 54.9% bore interest at fixed rates. The percentage of our total debt investments that bore floating rate interest subject to an interest rate floor was 40.2% at December 31, 2012.

The Advisor employs a grading system for our entire portfolio. The Advisor grades all loans on a scale of 1 to 4. This system is intended to reflect the performance of the borrower’s business, the collateral coverage of the loans and other factors considered relevant. Generally, the Advisor assigns only one loan grade to each portfolio company for all loan investments in that portfolio company; however, the Advisor will assign multiple ratings when appropriate for different investments in one portfolio company. The following is a description of the conditions associated with each investment rating:

Grade 1: Investments in portfolio companies whose performance is substantially within the Advisor’s expectations and whose risk factors are neutral to favorable to those at the time of the original investment.

Grade 2: Investments in portfolio companies whose performance is below the Advisor’s expectations and that require closer monitoring; however, no loss of investment return (interest and/or dividends) or principal is expected.

Grade 3: Investments in portfolio companies whose performance is below the Advisor’s expectations and for which risk has increased materially since origination. Some loss of investment return is expected, but no loss of principal is expected. Companies graded 3 generally will be out of compliance with debt covenants and will be unlikely to make debt repayments on their original schedule.

Grade 4: Investments in portfolio companies whose performance is materially below the Advisor’s expectations where business trends have deteriorated and risk factors have increased substantially since the original investment. Investments graded 4 are those for which some loss of principal is expected.

The Advisor monitors and, when appropriate, changes the investment ratings assigned to each investment in our portfolio. In connection with our valuation process, the Advisor and Board of Directors review these investment ratings on a quarterly basis. Our average investment rating was 1.21 at March 31, 2013 and 1.20 at December 31, 2012. The following is a distribution of the investment ratings of our portfolio companies at March 31, 2013 and December 31, 2012:


	March 31, 2013		December 31, 2012
Grade 1	$	858,620,115	$	890,646,222

Results of operations

Results comparisons for the three months ended March 31, 2013 and 2012.

Investment income

Investment income totaled $31,129,502 and $33,206,665, respectively, for the three months ended March 31, 2013 and 2012, of which $17,304,768 and $22,541,644 were attributable to interest and fees on senior secured loans, $13,779,002 and $10,334,469 to interest and fees earned on other debt securities, $43,435 and $328,030 to dividends from preferred equity securities and $2,297 and $2,522 to interest earned on cash equivalents, respectively. For the three months ended March 31, 2013 and 2012 investment income included fees of $2,762,406 and $3,485,540, respectively. For the three months ended March 31, 2013 fee income included $2,037,683 from fees earned on early repayments of loans as well as amortization of fees and $724,723 of commitment and capital structuring fees. Interest income earned is comprised of cash interest of approximately 93% as well as PIK interest of approximately 7% for the three months ended March 31, 2013. The decrease in investment income for the current period reflects the reduction in the overall size of our portfolio as a result of early repayments.

Expenses

Expenses for the three months ended March 31, 2013 and 2012 were $18,165,424 and $14,182,453, respectively, which consisted of $5,349,956 and $5,390,448 in base management fees, $5,264,110 and $2,213,859 in incentive management fees, $4,758,016 and $4,712,943 in interest expense and fees related to the Credit Facility, Convertible Notes and Senior Secured Notes, $630,197 and $118,854 in professional fees, $558,098 and $363,685 in Advisor expenses, $366,006 and $627,779 in amortization of debt issuance costs, $251,316 and $82,331 in administrative services, $118,000 and $120,766 in director fees, and $869,725 and $551,788 in other expenses, respectively. The increase in expenses for the three months ended March 31, 2013 were due to the increase in incentive fee from gain. Total incentive fees were $5,264,110 which is comprised of incentive fees from income of $1,543,384 and $3,720,726 of hypothetical incentive fee from gain for the three months ended March 31, 2013. The total incentive fees from income and total incentive fees from gains were $2,213,859 and zero for the three months ended March 31, 2012, respectively.

Net investment income

Net investment income was $12,964,078 and $19,024,212 for the three months ended March 31, 2013 and 2012, respectively. The decrease is primarily a result of a decrease in interest and fee income and an increase in expenses for incentive fees.

Net realized gain or loss

Net realized gain of $213,342 for the three months ended March 31, 2013 was mainly the result of net gains on foreign currency transactions. Net realized loss of $317,969 for the three months ended March 31, 2012 was the result of $147,394 in net losses from the expiration of an equity warrant and $170,575 in net loss realized on foreign currency transactions.

Net unrealized appreciation or depreciation

For the three months ended March 31, 2013 and 2012, the change in net unrealized appreciation or depreciation was an increase in net unrealized appreciation of $16,619,719 and a decrease in net unrealized depreciation $1,592,001, respectively. The increase in net unrealized appreciation for the three months ended March 31, 2013 was comprised of an increase in net unrealized appreciation on investments of $16,369,689 and a net unrealized foreign currency translation gain of $250,030. The decrease in net unrealized depreciation for the three months ended March 31, 2012 was comprised of a decrease in net unrealized depreciation on investments of $893,223 and a net unrealized foreign currency translation gain of $698,778.

Net increase in net assets resulting from operations

The net increase in net assets resulting from operations for the three months ended March 31, 2013 and 2012 was $29,797,139 and $20,298,244, respectively. The increase primarily reflects the increase in net unrealized appreciation partially offset by an increase in expenses for the three months ended March 31, 2013.

Supplemental Non-GAAP information

We report our financial results on a GAAP basis; however, management believes that evaluating our ongoing operating results may be enhanced if investors have additional non-GAAP basis financial measures. Management reviews non-GAAP financial measures to assess ongoing operations and, for the reasons described below, considers them to be effective indicators, for both management and investors, of our financial performance over time. Management does not advocate that investors consider such non-GAAP financial measures in isolation from, or as a substitute for, financial information prepared in accordance with GAAP.

We record our liability for Incentive Fees as we become legally obligated to pay them, based on a hypothetical liquidation at the end of each reporting period. Our obligation to pay Incentive Fees with respect to any fiscal quarter is based on a formula that reflects our results over a trailing four-fiscal quarter period ending with the current fiscal quarter. We are legally obligated to pay the amount resulting from the formula less any cash payments of Incentive Fees during the prior three quarters. The formula’s requirement to reduce the Incentive Fees by amounts paid with respect to Incentive Fees in the prior three quarters has caused our Incentive Fees expense to become, generally concentrated in the fourth quarter of each year. Management believes that reflecting Incentive Fees throughout the year, as the related investment income is earned on a quarterly basis, is an effective measure of our profitability and financial performance that facilitates comparison of current results with historical results and with those of our peers. Our “as adjusted” results reflect Incentive Fees based on the formula we utilize for each trailing four-fiscal quarter period, with the formula applied to the current quarter’s incremental earnings and without any reduction for Incentive Fees paid during the prior three quarters. The resulting amount represents an upper limit of each quarter’s incremental Incentive Fees that we may become legally obligated to pay at the end of the year. Prior year amounts are estimated in the same manner. These estimates represent upper limits because, in any calendar year, subsequent quarters’ investment underperformance could reduce the Incentive Fees payable with respect to prior quarters’ operating results. Changes in the economic environment, financial markets and other parameters used in determining such estimates could cause actual results to differ and such differences could be material. See Note 3 to the consolidated financial statements in this Quarterly Report for a more detailed description of the Company’s incentive management fee.

Computations for all periods are derived from our consolidated financial statements as follows:


	Three months ended March 31, 2013		Three months ended March 31, 2012
GAAP Basis:
Net Investment Income	$	12,964,078	$	19,024,212

Net Increase in Net Assets from Operations per share		0.45		0.27

Pre-Incentive Fee¹: Amounts are adjusted to remove all incentive management fees. Such fees are calculated but not necessarily due and payable at this time.

As Adjusted²: Amounts are adjusted to remove the incentive management fee expense based on Gains, as required by GAAP, and to include only the incremental incentive management fee expense based on Income. The incremental incentive management fee is based on the formula the Company utilizes for each trailing four-fiscal quarter period, with the formula applied to the current quarter’s incremental earnings, and without any reduction for incentive management fees paid during the prior three quarters. Amounts reflect the Company’s ongoing operating results and are the most effective indicator of the Company’s financial performance over time.

Financial condition, liquidity and capital resources

During the three months ended March 31, 2013, we generated operating cash flows primarily from loan repayments, interest earned and fees received on senior secured loans and other debt securities, as well as from sales and unsettled purchases of selected portfolio company investments or repayments of principal.

Net cash provided by operating activities during the three months ended March 31, 2013 was $49,607,189. Our primary sources of cash from operating activities during the period consisted of a net increase in net assets from operations of $29,797,139, and net proceeds from repayments (net of purchases of $46,026,548) of $58,186,373 which was partially offset by the net change in unrealized appreciation on investments.

Net cash used in financing activities during the three months ended March 31, 2013 was $57,763,469. Our primary use of cash for financing activities was $39,822,345 in repayments net of borrowings under the Credit Facility and Convertible Notes. An additional use of cash for financing activities was $17,941,124 of dividend distributions.

On March 13, 2013 we entered into an Amended and Restated Senior Secured Revolving Credit Facility (“Credit Facility”) which has an initial aggregate principal amount of up to $350,000,000 and canceled the prior credit facility and the related term loan that were outstanding at December 31, 2012. The Credit Facility has a stated maturity date of March 13, 2017. The interest rate applicable to borrowings thereunder is generally LIBOR plus an applicable margin of 2.50%. The Credit Facility’s commitment may increase in size, under certain circumstances, up to a total of $750,000,000.

On February 19, 2013 the Company closed a private offering of $100,000,000 in aggregate principal amount of 5.50% unsecured convertible senior notes due 2018 (the “Convertible Notes”). The initial purchasers of the Convertible Notes fully exercised their overallotment option and purchased an additional $15,000,000 in aggregate principal amount of the Convertible Notes. The closing of the overallotment option took place on March 4, 2013. With the exercise of the overallotment option, a total of $115,000,000 in aggregate principal amount of the Convertible Notes have been sold. Net proceeds to the Company from the offering, including the exercise of the overallotment option, were approximately $111,300,000. The Convertible Notes were only offered to qualified institutional buyers as defined in the Securities Act of 1933, as amended pursuant to Rule 144A under the Securities Act.

Contractual obligations

A summary of our significant contractual payment obligations for the repayment of outstanding borrowings at March 31, 2013 is as follows:


	Payments Due By Period (dollars in millions)
	Total		Less than 1 year		1-3 years		3-5 years		After 5 years
Credit Facility(1)	$	17.0	$	—	$	—	$	17.0	$	—

(1)	At March 31, 2013, $333.0 million remained unused under our Credit Facility.

Off-balance sheet arrangements

Dividends

Our quarterly dividends, if any, are determined by our Board of Directors. Dividends are declared considering our estimate of annual taxable income available for distribution to stockholders and the amount of taxable income carried over from the prior year for distribution in the current year. We cannot assure stockholders that they will receive any dividends and distributions at all or dividends and distributions at a particular level. The following table lists the quarterly dividend per share from our common stock since March 2011.


Dividend Amount Per Share Outstanding	Record Date	Payment Date
$0.32	March 18, 2011	April 1, 2011
$0.26	June 17, 2011	July 1, 2011
$0.26	September 19, 2011	October 3, 2011
$0.26	December 21, 2011	January 4, 2012
$0.26	March 20, 2012	April 3, 2012
$0.26	June 19, 2012	July 3, 2012

$0.26	March 19, 2013	April 2, 2013
$0.26	June 18, 2013	July 2, 2013

Tax characteristics of all dividends are reported to stockholders on Form 1099 after the end of the calendar year.

We have elected to be taxed as a RIC under Subchapter M of the Code. In order to maintain favorable RIC tax treatment, we must distribute annually to our stockholders at least 90% of our ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, if any, out of the assets legally available for distribution. Under the Regulated Investment Company Modernization Act of 2010, capital losses incurred by the Company after December 31, 2010 will not be subject to expiration. In addition, such losses must be utilized prior to the losses incurred in the years preceding enactment. In order to avoid certain excise taxes imposed on RICs, we must distribute during each calendar year an amount at least equal to the sum of:

•

98% of our ordinary income for the calendar year;

•

98.2% of our capital gains in excess of capital losses for the one-year period ending on October 31st; and

•

any ordinary income and net capital gains for preceding years that were not distributed during such years.

We maintain an “opt out” dividend reinvestment plan for our common stockholders. As a result, except as discussed below, if we declare a dividend, stockholders’ cash dividends will be automatically reinvested in additional shares of our common stock, unless they specifically “opt out” of the dividend reinvestment plan so as to receive cash dividends. With respect to our dividends and distributions paid to stockholders during the three months ended March 31, 2013 and 2012, dividends reinvested pursuant to our dividend reinvestment plan totaled $1,255,294 and $1,734,945, respectively.

Under the terms of an amendment to our dividend reinvestment plan adopted on March 4, 2009, dividends may be paid in newly issued or treasury shares of our common stock at a price equal to 95% of the market price on the dividend payment date. This feature of the plan means that, under certain circumstances, we may issue shares of our common stock at a price below net asset value per share, which could cause our stockholders to experience dilution. We may not be able to achieve operating results that will allow us to make dividends and distributions at a specific level or to increase the amount of these dividends and distributions from time to time. Also, we may be limited in our ability to make dividends and distributions due to the asset coverage test applicable to us as a BDC under the 1940 Act and due to provisions in our existing and future debt arrangements.

If we do not distribute a certain percentage of our income annually, we will suffer adverse tax consequences, including possible loss of favorable RIC tax treatment. In addition, in accordance with U.S. generally accepted accounting principles and tax regulations, we include in income certain amounts that we have not yet received in cash, such as payment-in-kind interest, which represents contractual interest added to the loan balance that becomes due at the end of the loan term, or the accrual of original issue or market discount. Since we may recognize income before or without receiving cash representing such income, we may have difficulty meeting the requirement to distribute at least 90% of our investment company taxable income to obtain tax benefits as a RIC and may be subject to an excise tax. In order to satisfy the annual distribution requirement applicable to RICs, we have the ability to declare a large portion of a dividend in shares of our common stock instead of in cash. As long as a portion of such dividend is paid in cash (which portion can be as low as 10% for our taxable years ending prior to 2012) and certain requirements are met, the entire distribution would be treated as a dividend for U.S. federal income tax purposes.

With respect to dividends paid to stockholders, certain income we receive from origination, structuring, closing, commitment and other upfront fees associated with investments in portfolio companies may cause our taxable income to exceed our GAAP income although the differences are expected to be temporary in nature.

Recent developments

On May 1, 2013, the Company’s Board of Directors declared a dividend of $0.26 per share, payable on July 2, 2013 to stockholders of record at the close of business on June 18, 2013.

Notice is hereby given in accordance with Section 23(c) of the 1940 Act that from time to time the Company may purchase shares of its common stock in the open market at prevailing market prices.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are subject to financial market risks, including changes in interest rates. At March 31, 2013, 49.6% of our debt investments bore interest based on floating rates, such as LIBOR, the Federal Funds Rate or the Prime Rate. The interest rates on such investments generally reset by reference to the current market index after one to six months. At March 31, 2013, the percentage of our total debt investments that bore floating rate interest based on an interest rate floor was 47.6%. Floating rate investments subject to a floor generally reset by reference to the current market index after one to six months only if the index exceeds the floor.

While hedging activities may help to insulate us against adverse changes in interest rates, they also may limit our ability to participate in the benefits of lower interest rates with respect to our portfolio of investments. During the three months ended March 31, 2013 and 2012, we did not engage in any interest rate hedging activity.

Item 4. Controls and Procedures

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15 under the Securities Exchange Act of 1934). Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our current disclosure controls and procedures are effective in timely alerting them to material information relating to us that is required to be disclosed by us in the reports we file or submit under the Securities Exchange Act of 1934.

There have been no changes in our internal control over financial reporting that occurred during our most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we and the Advisor may be a party to certain legal proceedings incidental to the normal course of our business, including the enforcement of our rights under contracts with our portfolio companies. While we cannot predict the outcome of these legal proceedings with certainty, we do not expect that these proceedings will have a material effect on our consolidated financial statements.

Item 1A. Risk Factors

There have been no material changes from the risk factors previously disclosed in our most recent Form 10-K filing.
