London Interbank Offered Rate (LIBOR) or other base rate (commonly the Federal Funds Rate or the Prime Rate), at the borrowers option. In addition, approximately 63% of such senior secured loans have floors of 1.00% to 3.25%. The borrower
under a senior secured loan generally has the option to select from interest reset periods of one, two, three or six months and may alter that selection at the end of any reset period. The stated interest rate represents the weighted average
interest rate at June 30, 2012 of all contracts within the specified loan facility.

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, 2011, which was filed with the Securities and Exchange Commission (SEC) on March 1, 2012.

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.

##### Table of Contents

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 valued 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 investments in a money market fund.

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.

Structuring service 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 in these situations
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.

##### Table of Contents

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.

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 $22,973,410 and $26,165,703 as of June 30, 2012 and December 31, 2011, 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 May 2011, the FASB
issued ASU 2011-04, Fair Value Measurement: Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs(ASU 2011-04), which amends the existing fair value guidance within ASC 820-10. The
amendments include: (1) application of the concepts of highest and best use and valuation premise only to measuring the fair value of nonfinancial assets (that is, it does not apply to financial assets or any liabilities), (2) an exception
to fair value measurement principles for financial assets and financial liabilities (and derivatives) with offsetting positions in market risks or counterparty credit risk, which allows an entity to measure the fair value of the net risk position,
when several criteria are met, (3) extension of the prohibition of a blockage factor application to all fair value measurements, (4) a model for the fair value measurement of instruments classified within an entitys
shareholders equity which is consistent with the guidance of measuring the fair value for liabilities, (5) additional disclosures for fair value measurements categorized in Level 3 of the fair value hierarchy: (i) quantitative
information about unobservable inputs used, (ii) a description of the valuation processes used by the entity and (iii) a qualitative discussion about the sensitivity of the measurements, (6) disclosure of the level in the fair value
hierarchy of assets and liabilities not recorded at fair value but where fair value is disclosed and (7) disclosure of any transfers between Levels 1 and 2 of the fair value hierarchy, not just significant transfers. The provisions of ASU
2011-04 were effective for the Company on January 1, 2012. Management has adopted the provisions of ASU 2011-04 on January 1, 2012. The adoption of ASU 2011-04 did not have an impact on the measurement of fair value of the Companys
investments, but did impact the Companys disclosures related to fair value, which have been reflected in the notes to these consolidated financial statements.

In December 2011, FASB issued ASU 2011-11, Balance Sheet: 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 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. Management is currently evaluating the implications
of ASU 2011-11 and its impact on financial statement disclosures.

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 and six months ended June 30, 2012,
the Advisor earned $5,522,189 and $10,912,637, respectively, in Management Fees under the Management Agreement. For the three and six months ended June 30, 2011, the Advisor earned $4,958,231 and $9,423,470, respectively, in such fees from the
Company.

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 June 30, 2012 and 2011 was determined by reference to the four quarter periods ended on
June 30, 2012 and 2011, 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.

Annual Incentive Fee Based on Capital Gains. The portion of the Incentive Fee based on capital gains is calculated on an annual basis. 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.

##### Table of Contents

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.

For the three and six months ended June 30, 2012, the Advisor earned zero and
$2,213,859, respectively, in Incentive Fees from the Company. For the three and six months ended June 30, 2011, the Advisor earned no such fees.

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 and six months ended June 30, 2012, the Company incurred $488,961 and $852,646, respectively, for such
investment advisor expenses under the Management Agreement. Reimbursements to the Advisor for such investment advisor expenses for the three and six months ended June 30, 2011 were $435,530 and $861,015, respectively.

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 such purposes during the three and six months ended June 30, 2012 were $981,481 and $1,462,503, respectively. Reimbursements to the
Advisor for such purposes during the three and six months ended June 30, 2011 were $421,803 and $767,323, 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 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 and six months ended June 30, 2012, the Company incurred
$117,478 and $148,184, respectively, for administrative services expenses payable to the Administrator under the administration agreement. For the three and six months ended June 30, 2011, the Company incurred $203,263 and $445,225,
respectively, in such expenses.

and Canada 3.9%, and at December 31, 2011 was United States 96.0% and Canada 4.0%. The geographic composition is determined by the location of the corporate headquarters of the portfolio company.

Market, Credit and Industry 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.

##### Table of Contents

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 June 30, 2012, details of open forward foreign currency contracts were
as follows:

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 June 30, 2012 and December 31, 2011 represents 1.4% and 0.9%,
respectively, of the Companys net assets.

7. Debt

Under the terms of the Companys amended and restated Senior Secured, Multi-Currency Credit Agreement (the Credit Facility), as amended on April 20, 2010, certain lenders agreed to
extend credit to the Company in an aggregate principal amount not to exceed $375,000,000 outstanding, at any one time, consisting of $275,000,000 of revolving loan commitments and $100,000,000 of term loan commitments. The Credit Facility is secured
by substantially all of the assets in the Companys portfolio, including cash and cash equivalents. Subject to certain exceptions, pricing for outstanding borrowings is at LIBOR plus an applicable spread of either 3.00% or 3.25% for revolving
loans, based on a pricing grid using the Companys credit rating, and LIBOR plus 3.00% for term loans. The Credit Facility does not contain a LIBOR floor requirement. At June 30, 2012, the effective LIBOR spread under the Credit Facility
was 2.95%. Term loan commitments under the Credit Facility have been fully drawn and, once repaid, may not be reborrowed. The Credit Facility also includes an accordion feature that allows the Company, under certain circumstances, to
increase the size of the Credit Facility by up to an additional $275,000,000 of revolving loan commitments and $250,000,000 of term loan commitments. The Credit Facility is used to supplement the Companys equity capital to make additional
portfolio investments and for other general corporate purposes.

At June 30, 2012, the Company had $274,900,000 drawn on
the Credit Facility versus $168,000,000 at December 31, 2011. Subject to compliance with applicable covenants and borrowing base limitations, the remaining amount available under the Credit Facility was $100,100,000 at June 30, 2012.

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.

The Companys average outstanding debt balance during the three and six months ended June 30, 2012 was $395,902,747 and $375,555,525, respectively. The maximum amounts borrowed during the three
and six months ended June 30, 2012 were $451,400,000 and $451,400,000, respectively, and during the three and six months ended June 30, 2011 were $278,000,000 and $356,500,000

The weighted average annual interest cost for the three and six months ended June 30, 2012 was 4.89% and 4.96%, respectively, and for
the three and six months ended June 30, 2011 was 5.37% and 5.27%, exclusive of commitment fees and of other prepaid expenses related to establishing the Credit Facility and the Senior Secured Notes. With respect to any unused portion of the
commitments under the Credit Facility, the Company incurs an annual commitment fee of 0.50%. Commitment fees incurred for the three and six months ended June 30, 2012 were $194,761 and $446,999, respectively, and for the three and six months
ended June 30, 2011 were $344,430 and $665,972.

At June 30, 2012, the Company was in compliance with all covenants
required under the Credit Facility 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 and six months ended June 30, 2012, the Company purchased zero shares of its
common stock on the open market. During the six months ended June 30, 2011, the Company purchased a total of 200,000 shares of its common stock on the open market for $2,003,040, including brokerage commissions. There were no such purchases
during the three months ended June 30, 2011. Since inception of the repurchase plan through June 30, 2012, the Company has purchased 1,425,507 shares of its common stock on the open market for $9,476,676, including brokerage commissions.
At June 30, 2012, 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 June 30, 2012 and December 31, 2011, and periods then ended.

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.

##### Table of Contents

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 and Senior Secured

In determining the fair values of the Companys forward foreign currency contracts at June 30,
2012 and at December 31, 2011, the Company used unadjusted indicative price quotations for similar assets (Level 2).

The
valuation techniques used at June 30, 2012 and December 31, 2011 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 $1,165,232,950 and $1,043,181,658 as of June 30, 2012 and
December 31, 2011, respectively. The remaining balance was determined using broker quotes for identical or similar assets.

There were no transfers between levels during the six months ended June 30, 2012 and 2011. 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 ranges of unobservable inputs used in the fair value measurement of the Companys Level 3 investments as of June 30, 2012
were as follows:



|                 |  |  |               | 
|---------------- |  |  | ------------- | 
|EBITDA Multiples |  |  | 2.5x to 11.0x | 
|Market Yields    |  |  | 7.5% to 19.5% | 

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 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.

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



41



---

##### Table of Contents

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 most 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, interest and credit facility fees, 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.

Portfolio and investment activity

During the three months ended
June 30, 2012, we invested approximately $148.2 million across two new and several existing portfolio companies. The investments consisted primarily of senior secured loans secured by first liens ($33.7 million, or 23%), or second liens ($47.4
million, or 32%), senior secured notes ($23.0 million, or 15%) and unsecured or subordinated debt securities and equity securities ($44.1 million, or 30%). Additionally, we received proceeds from sales/repayments and other exits of
approximately $80.5 million during the three months ended June 30, 2012.

At June 30, 2012, our portfolio of
$1,177.0 million (at fair value) consisted of 53 portfolio companies and was invested 55% in senior secured loans, 18% in unsecured or subordinated debt securities, 15% in senior secured notes, 11% in equity investments and 1% in cash and cash
equivalents. At June 30, 2012 our average portfolio company at amortized cost was approximately $21.5 million. Excluding our investments with amortized cost less than $5.0 million, our average portfolio company at amortized cost was $25.0
million at June 30, 2012. Our largest portfolio company investment by value was approximately $52.5 million and our five largest portfolio company investments by value comprised approximately 20% of our portfolio at June 30, 2012. At
December 31, 2011, our portfolio of $1,056.7 million (at fair value) consisted of 54 portfolio companies and was invested 62% in senior secured loans, 16% in unsecured or subordinated debt securities, 11% in senior secured notes, 11% in equity
investments and less than 1% in cash and cash equivalents. At December 31, 2011 our average portfolio company at amortized cost was approximately $20.3 million. Excluding our investments with amortized cost less than $5.0 million, our average
portfolio company at amortized cost was $24.0 million at December 31, 2011. Our largest portfolio company investment by value was approximately $50.0 million and our five largest portfolio company investments by value comprised approximately
21% of our portfolio at December 31, 2011.

The weighted average yield of the debt and income producing equity securities
in our portfolio at fair value was 12.5% at June 30, 2012 and 12.7% at December 31, 2011. The weighted average yields on our senior

##### Table of Contents

secured loans and other debt securities at fair value were 11.8% and 13.7%, respectively, at June 30, 2012, versus 12.2% and 13.5% at December 31, 2011. The weighted average yield of
the debt and income producing equity securities in our portfolio at their current cost basis was 12.4% at June 30, 2012 and 11.9% at December 31, 2011. The weighted average yields on our senior secured loans and other debt securities at
their current cost basis were 11.7% and 13.8%, respectively, at June 30, 2012, versus 12.0% and 11.4% at December 31, 2011. Yields are computed using interest rates and dividend yields as of the balance sheet date and include amortization
of loan origination fees, original issue discount and market premium or discount based on the expected cash flows of the respective portfolio investment. Yields exclude common equity investments, preferred equity investments with no stated dividend
rate, short-term investments and cash and cash equivalents.

At June 30, 2012, 47.8% of our debt investments bore interest
based on floating rates, such as LIBOR, the Federal Funds Rate or the Prime Rate, and 52.2% bore interest at fixed rates. The percentage of our total debt investments that bore floating rate interest based on an interest rate floor was 42.3% at
June 30, 2012. At December 31, 2011, 50.6% of our debt investments bore interest based on floating rates, such as LIBOR, the Federal Funds Rate or the Prime Rate, and 49.4% bore interest at fixed rates. The percentage of our total debt
investments that bore floating rate interest subject to an interest rate floor was 43.8% at December 31, 2011.

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 1.17 at June 30, 2012 versus 1.20 at December 31, 2011. The following is a distribution
of the investment ratings of our portfolio companies at June 30, 2012 and December 31, 2011:

Investment income totaled $35,466,277 and $37,106,568, respectively, for the three months ended June 30, 2012 and 2011, of which $23,035,790 and $13,920,583 were attributable to interest and fees on
senior secured loans, $12,088,750 and $21,676,121 to interest earned on other debt securities, $339,282 and $1,467,744 to dividends from equity securities, $2,455 and $4,620 to interest earned on cash equivalents and zero and $37,500 to other
income, respectively. The decrease in investment income for the three months ended June 30, 2012 is primarily attributable to interest and one-time fees collected from the early repayment of one of our largest portfolio companies during the
three months ended June 30, 2011.

For the three months ended June 30, 2012 fee income included $1,644,240 from fees
earned on early repayments of loans as well as amortization of fees and $2,170,250 of amendment and capital structuring fees. Interest income earned is comprised of cash interest of approximately 96% as well as PIK interest of approximately 4% for
the three months ended June 30, 2012. The decrease in fee income for the three months ended June 30, 2012 is primarily attributable to one-time fees collected from the early repayment of one of our largest portfolio companies during the
three months ended June 30, 2011.

Expenses

Expenses for the three months ended June 30, 2012 and 2011 were $13,083,040 and $11,367,334, respectively, which consisted of
$5,522,189 and $4,958,231 in base management fees, $5,024,200 and $4,052,052 in interest expense and fees related to the Credit Facility, $627,780 and $627,779 in amortization of debt issuance costs, $488,961 and $435,530 in Advisor expenses,
$384,677 and $303,457 in professional fees, $170,203 and $255,819 in administrative services, $112,797 and $104,000 in director fees and $752,233 and $630,466 in other expenses, respectively. The increase in base management fees in the current
period reflects the overall growth and appreciation in value of our portfolio. The increase in interest and credit facility related expenses during the 2012 period is mainly a result of increased borrowing levels, as well as the issuance of $175
million in aggregate principal amount of our senior secured notes during January 2011. Total borrowings were $449,900,000 at June 30, 2012, compared to $275,000,000 at June 30, 2011.

Net investment income

Net investment income was $22,383,237 and $25,739,234 for the three months ended June 30, 2012 and 2011, respectively. The decrease is primarily a result of interest and one-time fees collected from
the early repayment of one of our largest portfolio company investments during the 2011 period, as well as an increase in base management fees and interest and credit facility related expenses during the current period.

Net realized gain or loss

Net realized loss of $75,915,238 for the three months ended June 30, 2012 was the result of $75,506,101 in net losses realized from the disposition of our investments and $409,137 in net loss
realized on foreign currency transactions. Net realized loss of $707,774 for the three months ended June 30, 2011 was the result of $29,587 in net losses realized from the disposition of our investments and $678,187 in net loss realized on
foreign currency transactions. Foreign currency losses mainly represent net losses on forward currency contracts used to mitigate the impact that changes in foreign exchange rates would have on our investments denominated in foreign currencies. Net
realized loss on investments for the three months ended June 30, 2012 resulted primarily from the disposition or restructurings of our investments in Big Dumpster Acquisition, Inc. et al. and WBS Group Holdings, LLC. Nearly the entire net
realized loss on investments represents amounts that had been reflected in unrealized depreciation on investments in prior periods.

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.

Financial condition, liquidity and capital resources

During the six months ended June 30, 2012, we generated operating cash flows primarily from 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 used in operating activities during the six months ended June 30, 2012 was $68,049,857. Our primary sources of cash from operating activities during the period consisted of a net increase in
net assets from operations of $41,280,384, which was more than offset by purchases of investments in portfolio companies (net of sales and repayments) of $100,452,340.

Net cash provided by financing activities during the six months ended June 30, 2012 was $71,753,738. Our primary source of cash for financing activities was $106,900,000 in proceeds from borrowings,
net of repayments under the Credit Facility. An additional use of cash for financing activities was $35,146,262 of dividend distributions.

Our senior secured, multi-currency Credit Facility provides us with $375,000,000 in total
availability, consisting of $275,000,000 of revolving loan commitments and $100,000,000 of term loan commitments. The Credit Facility is secured by substantially all of the assets in the Companys portfolio, including cash and cash equivalents.
The Credit Facility has a stated maturity date of December 6, 2013 and the interest rate applicable to borrowings thereunder is generally LIBOR plus an applicable spread of either 3.00% or 3.25% for revolving loans, based on a pricing grid
depending on the Companys credit rating, and LIBOR plus 3.00% for term loans. The Credit Facility does not contain a LIBOR floor requirement. At June 30, 2012, the effective LIBOR spread under the Credit Facility was 2.95%. Term loan
commitments under the Credit Facility have been fully drawn and, once repaid, may not be reborrowed. The Credit Facility also includes an accordion feature that allows the Company, under certain circumstances, to increase the size of the
Credit Facility by up to an additional $275,000,000 of revolving loan commitments and $250,000,000 of term loan commitments. The Credit Facility is used to supplement the Companys equity capital to make additional portfolio investments and for
other general corporate purposes. At June 30, 2012, we had $274,900,000 drawn and outstanding under the Credit Facility, with $100,100,000 available to us, subject to compliance with customary affirmative and negative covenants, including the
maintenance of a minimum stockholders equity, the maintenance of a ratio of not less than 200% of total assets (less total liabilities other than indebtedness) to total indebtedness, and restrictions on certain payments and issuance of debt.
At June 30, 2012, the Company was in compliance with regulatory coverage requirements with an asset coverage ratio of approximately 255% and was in compliance with all financial covenants under our debt agreements. In addition, borrowings under
the Credit Facility (and the incurrence of certain other permitted debt) are subject to compliance with a borrowing base that applies different advance rates to different types of assets in the Companys portfolio.

In January 2011, the Company closed a private placement issuance of $158,000,000 in aggregate principal amount of 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 Senior Secured Notes with a fixed interest rate of 6.60% and a maturity date of January 18, 2018. Interest
on the Senior Secured Notes is due semi-annually on January 18 and July 18, commencing on July 18, 2011. The proceeds from the issuance of the Senior Secured Notes were used to fund new portfolio investments, reduce outstanding
borrowings under the Credit Facility and for general corporate purposes. The Senior Secured Notes contain customary affirmative and negative covenants substantially similar to those in our Credit Facility. At June 30, 2012, we were in
compliance with all financial and operational covenants required by the Credit Facility and Senior Secured Notes.

At
June 30, 2012, we had $11,483,288 in cash and cash equivalents.

The primary use of existing funds is expected to be
purchases of investments in portfolio companies, cash distributions to our stockholders, repayment of indebtedness and other general corporate purposes.

payment obligations for the repayment of outstanding borrowings at June 30, 2012 is as follows:

Off-balance sheet arrangements

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 June 30, 2012.

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 June 2010.

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

We have elected to be treated 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 six months ended June 30, 2012 and 2011, dividends reinvested pursuant to our dividend reinvestment plan totaled $2,984,740 and $4,543,659, 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 2, 2012, our Registration Statement on
Form N-2 was declared effective by the SEC. Under this Shelf Registration Statement, we can issue up to $1,500,000,000 of our common stock, preferred stock, debt securities, warrants representing rights to purchase shares of our common stock,
preferred stock or debt securities and subscription rights, or units in the public market.

On August 1, 2012, the
Companys Board of Directors declared a dividend of $0.26 per share, payable on October 3, 2012 to stockholders of record at the close of business on September 19, 2012.

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
June 30, 2012, 47.8% 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 June 30, 2012, the percentage of our total debt investments that bore floating rate interest based on an interest rate floor was 42.3%. 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.

To illustrate the potential impact of
changes in interest rates, the Administrator provided the following analysis based on our June 30, 2012 balance sheet and assuming no changes in our investment structure. Net asset value is analyzed using the assumptions that interest rates, as
defined by the LIBOR and U.S. Treasury yield curves, increase or decrease and that the yield curves of the rate shocks will be parallel to each other. Under this analysis, an instantaneous 100 basis point increase in LIBOR and U.S. Treasury yields
would cause a decline of approximately $5,400,000, or $0.07 per share, in the value of our net assets at June 30, 2012 and a corresponding 100 basis point decrease in LIBOR and U.S. Treasury yields would cause an increase of approximately
$5,600,000, or $0.08 per share, in the value of our net assets on that date.

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 and six months ended June 30, 2012 and 2011, we did
not engage in any interest rate hedging activity.
