rate (commonly the Federal Funds Rate or the Prime Rate), at the borrowers option. In addition, approximately 70% of such senior secured loans have floors of 0.50% to 1.50%. 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, 2014 of all contracts within the
specified loan facility.

rate (commonly the Federal Funds Rate or the Prime Rate), at the borrowers option. In addition, approximately 71% of such senior secured loans have floors of 1.00% to 1.75%. 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 December 31, 2013 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 is registered as an investment advisor under the Investment Advisers Act of 1940 (the Advisers Act).

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.

2. Significant accounting policies

Unaudited Interim Consolidated Financial Statements

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, 2013, which was filed with the Securities and Exchange Commission
(SEC) on March 6, 2014.

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.

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



21

##### Table of Contents

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



22

##### Table of Contents

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

##### Table of Contents

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.

Distributions 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 distributions and other permanent book and tax differences
are reclassified among the Companys capital accounts as of each year end. 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 $26,857,496 and $19,373,748 as of June 30, 2014 and December 31, 2013, respectively.

Distributions to Common Stockholders

Distributions to common stockholders are recorded on the ex-dividend date. The amount to be paid out as a distribution 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 distribution, 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 distributions.

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

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 was effective for the Company for the year ended
December 31, 2013, and did not have a material effect on the Companys consolidated financial statements.

In June 2013, the FASB
issued ASU No. 2013-08, Financial Services-Investment Companies (Topic 946): Amendments to the Scope, Measurement, and Disclosure Requirements (ASU 2013-08). ASU 2013-08 changes the approach to the assessment of whether a
company is an investment company, clarifies the characteristics of an investment company, provides comprehensive guidance for the investment company assessment and contains certain disclosure requirements. ASU 2013-08 was effective for interim and
annual reporting periods in fiscal years that begin after December 15, 2013. Earlier application is prohibited. This update was effective for the Company for the year ended 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 and six months ended June 30, 2014, the Advisor earned $6,109,949 and $12,270,568, respectively, in Management Fees under
the Management Agreement. For the three and six months ended June 30, 2013, the Advisor earned $5,189,226 and $10,539,182, respectively.

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



25

##### Table of Contents

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 and six months ended June 30, 2014 and 2013 was determined by reference to the four quarter periods ended
on June 30, 2014 and 2013, 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 and six months ended June 30, 2014 the Advisor earned zero and for the three and six months ended June 30, 2013 the
Advisor earned $374,584 and $1,917,968, 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, at June 30, 2014 was $16,152,709, which was previously accrued.

In accordance with GAAP the
hypothetical incentive fee for the three and six months ended June 30, 2014, resulted in a capital gains incentive fee of $2,968,924 and $6,428,789, respectively, and for the three and six months ended June 30, 2013, resulted in a capital
gains incentive fee of $1,695,021 and $5,415,747. The total cumulative balance at June 30, 2014 and 2013 was $32,182,873 and $10,910,482, 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 and six months ended June 30, 2014, the Company incurred $576,468 and $1,109,274, respectively, and for the three and six months ended June 30, 2013, the Company incurred $482,745 and $1,040,843,
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 such purposes during the three and six months ended June 30,
2014 were $422,945 and $1,209,402 respectively. Reimbursements to the Advisor for such purposes during the three and six months ended June 30, 2013 were $638,240 and $1,642,905, 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 and six months ended June 30, 2014, the Company incurred $128,045 and $282,466, respectively, for
administrative services expenses payable to the Administrator under the administration agreement. For the three and six months ended June 30, 2013, the Company incurred $131,432 and $332,715 respectively, in such expenses.

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. Pursuant to this authorization, during the six
months ended June 30, 2014 the Advisor purchased 84,600 shares of the Companys common stock in the open market for $716,146, including brokerage commissions. There were no such purchases during the six months ended June 30, 2013.

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. Pursuant to this authorization, on March 16, 2011, the Company
issued and sold to the Advisor in a private placement 200,000 shares of common stock for $2,000,000 or $10.00 per share, which was the closing price of the Companys common stock price on The NASDAQ Global Select Market on that date. There were
no private placement purchases during the three and six months ended June 30, 2014 and 2013.

At June 30, 2014 and
December 31, 2013, the Advisor owned and had the right to vote approximately 186,000 and 46,000 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 61,000 and 125,000 shares, respectively, of the Companys common stock. At June 30, 2014 and
December 31, 2013, other entities affiliated with the Administrator beneficially owned approximately 3,383,000 and 4,808,000 shares, respectively, of the Companys common stock, representing approximately 4.5% and 6.5% of the total shares
outstanding. An entity affiliated with the Administrator has ownership and financial interests in the Advisor.

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. There were no open forward foreign currency contracts at June 30, 2014 or December 31, 2013.

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, 2014 and December 31, 2013 represents 1.2% and 4.3%, respectively, of the Companys net assets.

The Company may enter into other derivative instruments and incur other exposures with other counterparties in the future. The derivative
instruments held as of June 30, 2014 and December 31, 2013 reflect the volume of derivative activity throughout the periods presented.

7.
Debt

In accordance with the 1940 Act, with certain limited exceptions, the Company is only allowed to borrow amounts such that its
asset coverage, calculated pursuant to the 1940 Act, is at least 200% after such borrowing. As of June 30, 2014, the Companys asset coverage was 316%.

On March 27, 2014, 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 $405,000,000 and canceled the prior credit facility that was outstanding at December 31, 2013. The Credit Facility has a stated maturity date of March 27, 2019. The interest rate
applicable to borrowings thereunder is generally LIBOR plus an applicable margin of 2.25%. The Credit Facilitys commitment may increase in size, under certain circumstances, up to a total of $750,000,000.

On March 27, 2014, the Company entered into an Amended and Restated Senior Secured Term Loan Credit Agreement (the Term Loan)
which has a principal amount of $15,000,000. The Term Loan has a stated maturity date of March 27, 2019. The interest rate applicable to borrowings thereunder is generally LIBOR plus an applicable margin of 3.25%.

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 was 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.

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

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

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 April 2014, the repurchase plan was further extended through the
earlier of June 30, 2015 or until the approved number of shares has been repurchased. During the six months ended June 30, 2014 and 2013 the Company purchased a total of 210,248 and zero shares, respectively of its common stock on the open
market for $1,779,619, including brokerage commissions. Since inception of the repurchase plan through June 30, 2014, the Company has purchased 1,635,755 shares of its common stock on the open market for $11,256,295, including brokerage
commissions. At June 30, 2014, the total number of remaining shares authorized for repurchase was 1,120,895. 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, 2014 and December 31, 2013.

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.

##### Table of Contents

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, the Senior Secured Notes, the Convertible Notes and
the Term Loan 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 outstanding debt as of June 30, 2014 and December 31, 2013 were as follows:

There were no transfers between Levels during the three months ended June 30, 2014 and 2013. 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.

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.



40



---

##### Table of Contents

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 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.

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 reflect the Companys financial performance over
time.

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 1.18 at June 30, 2014 and 1.14 at
December 31, 2013. The following is a distribution of the investment ratings of our portfolio companies at June 30, 2014 and December 31, 2013:

Investment income

Investment income totaled $33,761,759 and $36,136,223, respectively, for the three months ended June 30, 2014 and 2013, of which
$16,182,016 and $22,587,827 were attributable to interest and fees on senior secured loans, $17,010,274 and $12,927,881 to interest and fees earned on other debt securities, $567,751 and, $616,589 to dividends from equity securities and $1,718 and
$3,926 to interest earned on cash equivalents, respectively. The decrease in investment income for the three months ended June 30, 2014 is primarily attributable to a decrease in interest income.

For the three months ended June 30, 2014, fee income included $4,742,649 from fees from prepayment penalties in connection with the early
repayments of loans. Interest income earned is comprised of cash interest of approximately 97% as well as PIK interest of approximately 3%.

Expenses

Expenses for the three months ended June 30, 2014 and 2013 were $17,330,434 and $14,916,369, respectively, which consisted of $6,109,949
and $5,189,226 in base management fees, $5,614,533 and $4,915,024 in interest and credit facility fees, $2,968,924 and $2,069,605 of incentive management fees, $576,468 and $482,745 in investment advisor expenses, $519,071 and $496,542 in

Net realized gain or loss

Net realized gain was $48,996,726 for the three months ended June 30, 2014. Included in net realized gain is a realized gain of
$48,430,920 which was attributable to the sale of ECI Holdco, Inc. Nearly the entire realized gain was reflected in unrealized appreciation in prior periods. For the three months ended June 30, 2013 a net realized loss of $59,000,134 was due
almost entirely to losses relating to the restructuring of our investments in AGY Holding Corp., Bankruptcy Management Solutions, Inc. and Dial Global, Inc. et. al. Nearly the entire realized loss was reflected in unrealized depreciation in prior
periods. This loss was offset by a $605,768 net realized gain on foreign currency transactions.

Net unrealized appreciation or
depreciation

For the three months ended June 30, 2014 and 2013, the change in net unrealized appreciation or depreciation
was a decrease in net unrealized appreciation of $34,561,001 and an increase in net unrealized appreciation of $49,197,909, respectively. The majority of the decrease in net unrealized appreciation for the three months ended June 30, 2014 is
attributable to reversals due to the recognition of realized gains associated with the sale of ECI Holdco, Inc. The majority of the increase in net unrealized appreciation for the three months ended June 30, 2013 is attributable to reversals
due to the restructurings of our investments during the period, offset by a net unrealized foreign currency loss of $635,863.

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.

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 each trailing four-fiscal quarter period, 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 reflect the Companys financial performance over time.

Financial
condition, liquidity and capital resources

During the six months ended June 30, 2014, we generated operating cash flows primarily
from loan repayments, interest earned and fees received on senior secured loans and other debt securities.

Net cash provided by operating
activities during the six months ended June 30, 2014 was $246,481,374. Our primary sources of cash from operating activities during the period consisted of a net increase in net assets from operations of $53,783,659, and net proceeds from repayments
(net of purchases, including PIK of $153,474,723) of $227,038,137 which was partially offset by the change in receivables for investments sold.

Net cash used in financing activities during the three months ended June 30, 2014 was $187,116,926. Our primary use of cash for financing
activities was $148,877,915 in repayments net of borrowings under the Credit Facility. An additional use of cash for financing activities was $36,459,392 of distributions.

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, 2014.

Distributions

Our quarterly
distributions, if any, are determined by our Board of Directors. Distributions 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 distributions at all or distributions at a particular level. The following table lists the quarterly distributions per share from our common stock
since June 2012.

Tax characteristics of all distributions 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 distribution, stockholders cash distributions 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
distributions. With respect to our distributions paid to stockholders during the six months ended June 30, 2014 and 2013, distributions reinvested pursuant to our dividend reinvestment plan totaled $2,260,542 and $1,044,638, respectively.

Under the terms of an amendment to our dividend reinvestment plan adopted on March 4, 2009, distributions 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 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 distributions at a specific level or to increase the amount of these distributions from time to time. Also,
we may be limited in our ability to make 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.

Recent
developments

On July 29, 2014, the Companys Board of Directors declared a distribution of $0.21 per share, payable on
October 3, 2014 to stockholders of record at the close of business on September 19, 2014.

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, 2014, 48% 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, 2014, the percentage of our total debt investments that bore floating rate interest based on an interest rate floor was 45%. 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 six months ended
June 30, 2014 and 2013, 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.
