THE COMPANY

              This summary highlights some of the information contained elsewhere in this prospectus supplement and the accompanying prospectus. It is not complete and may not contain all of the information that you may want to consider. You should read carefully the more detailed information set forth under "Risk Factors" in the accompanying prospectus and the other information included in this prospectus supplement and the accompanying prospectus. Except where the context suggests otherwise, the terms "we," "us," "our," "the Company" and "Ares Capital" refer to Ares Capital Corporation and its consolidated subsidiaries; "Ares Capital Management" and "our investment adviser" refer to Ares Capital Management LLC; "Ares Operations" refers to Ares Operations LLC; and "Ares" and "Ares Management" refer to Ares Management LLC and its affiliated companies (other than portfolio companies of its affiliated funds).

Ares Capital

              Ares Capital, a Maryland corporation, is a specialty finance company that is a closed-end, non-diversified management investment company. We have elected to be regulated as a business development company, or a "BDC," under the Investment Company Act of 1940, as amended, and the rules and regulations promulgated thereunder or the "Investment Company Act." We were founded on April 16, 2004, were initially funded on June 23, 2004 and completed our initial public offering on October 8, 2004. We are one of the largest BDCs with approximately $7.8 billion of total assets as of September 30, 2013.

              We are externally managed by our investment adviser, Ares Capital Management, a wholly owned subsidiary of Ares Management, a global alternative asset manager and an SEC registered investment adviser with approximately $68 billion of committed capital under management as of September 30, 2013. Our administrator, Ares Operations, a wholly owned subsidiary of Ares Management, provides administrative services necessary for us to operate.

              Our investment objective is to generate both current income and capital appreciation through debt and equity investments. We invest primarily in U.S. middle-market companies, where we believe the supply of primary capital is limited and the investment opportunities are most attractive. However, we may from time to time invest in larger or smaller (in particular, for investments in early stage and/or venture capital-backed) companies. We generally use the term "middle-market" to refer to companies with annual EBITDA between $10 million and $250 million. As used herein, EBITDA represents net income before net interest expense, income tax expense, depreciation and amortization.

              We invest primarily in first lien senior secured loans (including unitranche loans), second lien senior secured loans and mezzanine debt, which in some cases includes an equity component. First and second lien senior secured loans generally are senior debt instruments that rank ahead of subordinated debt of a given portfolio company. Mezzanine debt is subordinated to senior loans and is generally unsecured. Our investments in corporate borrowers generally range between $30 million and $400 million each, investments in project finance/power generation projects generally range between $10 million and $200 million each and investments in early-stage and/or venture capital-backed companies generally range between $1 million and $25 million each. However, the investment sizes may be more or less than these ranges and may vary based on, among other things, our capital availability, the composition of our portfolio and general micro- and macro-economic factors.

              To a lesser extent, we also make preferred and/or common equity investments, which have generally been non-control equity investments of less than $20 million (usually in conjunction with a concurrent debt investment). However, we may increase the size or change the nature of these investments.

              The proportion of these types of investments will change over time given our views on, among other things, the economic and credit environment in which we are operating. In connection with our

investing activities, we may make commitments with respect to indebtedness or securities of a potential portfolio company substantially in excess of our final investment. In such situations, while we may initially agree to fund up to a certain dollar amount of an investment, we may subsequently syndicate a portion of such amount (including, without limitation, to vehicles managed by our portfolio company, Ivy Hill Asset Management, L.P. ("IHAM")), such that we are left with a smaller investment than what was reflected in our original commitment. In addition to originating investments, we may also acquire investments in the secondary market.

              The first and second lien senior secured loans in which we invest generally have stated terms of three to 10 years and the mezzanine debt investments in which we invest generally have stated terms of up to 10 years, but the expected average life of such first and second lien loans and mezzanine debt is generally between three and seven years. However, we may invest in loans and securities with any maturity or duration. The instruments in which we invest typically are not rated by any rating agency, but we believe that if such instruments were rated, they would be below investment grade (rated lower than "Baa3" by Moody's Investors Service, lower than "BBB-" by Fitch Ratings or lower than "BBB-" by Standard & Poor's Ratings Services), which, under the guidelines established by these entities, is an indication of having predominantly speculative characteristics with respect to the issuer's capacity to pay interest and repay principal. Bonds that are rated below investment grade are sometimes referred to as "high yield bonds" or "junk bonds." We may invest without limit in debt or other securities of any rating, as well as debt or other securities that have not been rated by any nationally recognized statistical rating organization.

              We believe that our investment adviser, Ares Capital Management, is able to leverage the current investment platform, resources and existing relationships of Ares with financial sponsors, financial institutions, hedge funds and other investment firms to provide us with attractive investment opportunities. In addition to deal flow, the Ares investment platform assists our investment adviser in analyzing, structuring and monitoring investments. Ares has been in existence for more than 15 years and its senior partners have an average of over 23 years of experience in leveraged finance, private equity, distressed debt, commercial real estate finance, investment banking and capital markets. The Company has access to Ares' investment professionals and administrative professionals, who provide assistance in accounting, finance, legal, compliance, operations, information technology and investor relations. As of September 30, 2013, Ares had 321 investment professionals and 402 administrative professionals.

              Since our initial public offering on October 8, 2004 through September 30, 2013, our realized gains have exceeded our realized losses by approximately $223 million (excluding the one-time gain on the acquisition of Allied Capital Corporation (the "Allied Acquisition") and gains/losses from the extinguishment of debt and other assets). For this same time period, our exited investments have resulted in an aggregate cash flow realized internal rate of return to us of approximately 13% (based on original cash invested, net of syndications, of approximately $7.4 billion and total proceeds from such exited investments of approximately $9.0 billion). Approximately 73% of these exited investments resulted in an aggregate cash flow realized internal rate of return to us of 10% or greater. Internal rate of return is the discount rate that makes the net present value of all cash flows related to a particular investment equal to zero. Internal rate of return is gross of expenses related to investments as these expenses are not allocable to specific investments. Investments are considered to be exited when the original investment objective has been achieved through the receipt of cash and/or non-cash consideration upon the repayment of a debt investment or sale of an investment or through the determination that no further consideration was collectible and, thus, a loss may have been realized. These internal rates of return results are historical results relating to our past performance and are not necessarily indicative of future results, the achievement of which cannot be assured.

              Additionally, since our initial public offering on October 8, 2004 through September 30, 2013, our average annualized net realized gain rate was approximately 1.1% (excluding the one-time gain on

the Allied Acquisition and realized gains/losses from the extinguishment of debt and from other assets). Net realized gain/loss rates are the amount of net realized gains/losses in a particular period divided by the average quarterly investments at amortized cost in the same period.

              We and General Electric Capital Corporation and GE Global Sponsor Finance LLC (collectively, "GE") also co-invest in first lien senior secured loans of middle market companies through an unconsolidated vehicle, the Senior Secured Loan Fund LLC, which operates using the name "Senior Secured Loan Program" (the "SSLP"). As of September 30, 2013, the SSLP had available capital of $9.0 billion of which approximately $7.6 billion in aggregate principal amount was funded. As of September 30, 2013, we had agreed to make available to the SSLP approximately $1.8 billion, of which approximately $1.6 billion was funded. The SSLP is capitalized as transactions are completed and all portfolio decisions and generally all other decisions in respect of the SSLP must be approved by an investment committee of the SSLP consisting of representatives of the Company and GE (with approval from a representative of each required). As of September 30, 2013, our investment in the SSLP was approximately $1.6 billion at fair value (including unrealized appreciation of $25.3 million), which represented approximately 22% of our total portfolio at fair value. See "Recent Developments" for more information on the SSLP.

              While our primary focus is to generate current income and capital appreciation through investments in first and second lien senior secured loans and mezzanine debt and, to a lesser extent, equity securities of eligible portfolio companies, we also may invest up to 30% of our portfolio in non-qualifying assets, as permitted by the Investment Company Act. See "Regulation" in the accompanying prospectus. Specifically, as part of this 30% basket, we may invest in entities that are not considered "eligible portfolio companies" (as defined in the Investment Company Act), including companies located outside of the United States, entities that are operating pursuant to certain exceptions under the Investment Company Act, and publicly traded entities whose public equity market capitalization exceeds the levels provided for under the Investment Company Act.

              In the first quarter of 2011, the staff of the SEC (the "Staff") informally communicated to certain BDCs the Staff's belief that certain entities, which would be classified as an "investment company" under the Investment Company Act but for the exception from the definition of "investment company" set forth in Rule 3a-7 promulgated under the Investment Company Act, could not be treated as "eligible portfolio companies" (as defined in Section 2(a)(46) under the Investment Company Act) (i.e., in a BDC's 70% basket of "qualifying assets"). Subsequently, in August 2011 the SEC issued a concept release (the "Concept Release") which stated that "[a]s a general matter, the Commission presently does not believe that Rule 3a-7 issuers are the type of small, developing and financially troubled businesses in which the U.S. Congress intended BDCs primarily to invest" and requested comment on whether or not a 3a-7 issuer should be considered an "eligible portfolio company." We provided a comment letter in respect of the Concept Release and continue to believe that the language of Section 2(a)(46) of the Investment Company Act permits a BDC to treat as "eligible portfolio companies" entities that rely on the 3a-7 exception. However, given the current uncertainty in this area (including the language in the Concept Release), we have, solely for purposes of calculating the composition of our portfolio pursuant to Section 55(a) of the Investment Company Act, identified such entities, which include the SSLP, as "non-qualifying assets" should the Staff ultimately take an official view that 3a-7 issuers are not "eligible portfolio companies."

              As of September 30, 2013, our portfolio company, IHAM, which became an SEC registered investment adviser effective March 30, 2012, managed 13 vehicles and served as the sub-manager/sub-servicer for three other vehicles (these vehicles managed or sub-managed/sub-serviced by IHAM are collectively referred to as the "IHAM Vehicles"), which are described in more detail under "Business—Investments—Ivy Hill Asset Management, L.P." in the accompanying prospectus. As of September 30, 2013, IHAM had total committed capital under management of approximately $3.1 billion, which included approximately $0.3 billion invested by Ares Capital in IHAM. In connection

with IHAM's registration as a registered investment adviser, on March 30, 2012, we received exemptive relief from the SEC allowing us to, subject to certain conditions, own directly or indirectly up to 100% of IHAM's outstanding equity interests and make additional investments in IHAM once IHAM became a registered investment adviser.

Ares Capital Management

              Ares Capital Management, our investment adviser, is served by an origination, investment and portfolio management team of 80 U.S.-based investment professionals as of September 30, 2013 and led by the senior partners of the Ares Management Private Debt Group: Michael Arougheti, Eric Beckman, Kipp deVeer, Mitchell Goldstein and Michael Smith. Ares Capital Management leverages off of Ares' investment platform and benefits from the significant capital markets, trading and research expertise of Ares' investment professionals. Ares Capital Management's investment committee has eight members, including the senior partners of the Ares Management Private Debt Group, senior partners in the Ares Management Private Equity Group and a senior adviser to the Ares Management Capital Markets Group.

Recent Developments

              In October 2013, we completed a public equity offering (the "October 2013 Offering") pursuant to which we sold to the participating underwriters 12,650,000 shares of common stock at a price of $16.98 per share. Total proceeds from the October 2013 Offering, net of estimated offering expenses payable by us, were approximately $214.2 million. We used the net proceeds of the October 2013 Offering to repay certain outstanding indebtedness under our debt facilities and for general corporate purposes, which included investing in portfolio companies in accordance with our investment objective.

              In October 2013, we increased total commitments of the Revolving Credit Facility (as defined below) from $1,035 million to $1,060 million.

              In November 2013, the SSLP's total available capital was increased from $9.0 billion to $11.0 billion. In connection with this increase, GE agreed to make available to the SSLP up to approximately $8.7 billion and we agreed to make available to the SSLP up to approximately $2.3 billion. Investment of any unfunded amount must be approved by an investment committee of the SSLP consisting of representatives of us and GE (with approval from a representative of each required).

              In November 2013, we declared the following dividends: (i) a fourth quarter 2013 dividend of $0.38 per share payable on December 31, 2013 to stockholders of record as of December 16, 2013, (ii) an additional dividend of $0.05 per share payable on December 31, 2013 to stockholders of record as of December 16, 2013 and (iii) another additional dividend of $0.05 per share payable on March 28, 2014 to stockholders of record as of March 14, 2014. Payment of the additional March 2014 dividend is subject to the satisfaction of certain Maryland law requirements.

              In November 2013, we issued $600 million aggregate principal amount of 4.875% senior notes due 2018 (the "2018 Notes") that will mature on November 30, 2018 unless previously redeemed in accordance with their terms. The 2018 Notes may be redeemed in whole or in part at our option at any time at the redemption prices set forth in the supplemental indenture governing the terms of the 2018 Notes. The 2018 Notes bear interest at a rate of 4.875% per year payable semiannually on May 30 and November 30 of each year, commencing on May 30, 2014. The 2018 Notes are our direct unsecured obligations.

              From October 1, 2013 through November 30, 2013, we made new investment commitments of $363 million, of which $317 million were funded. Of these new commitments, 50% were in first lien

senior secured loans, 28% were in senior subordinated debt, 21% were investments in subordinated certificates of the SSLP to make co-investments with GE in first lien senior secured loans through the SSLP and 1% were in second lien senior secured loans. Of the $363 million of new investment commitments, 72% were floating rate and 28% were fixed rate. The weighted average yield of debt and other income producing securities funded during the period at amortized cost was 10.7%. We may seek to syndicate a portion of these new investment commitments, although there can be no assurance that we will be able to do so.

              From October 1, 2013 through November 30, 2013, we exited $294 million of investment commitments. Of these investment commitments, 52% were first lien senior secured loans, 32% were second lien senior secured loans, 13% were investments in subordinated certificates of the SSLP, 2% were preferred equity securities and 1% were other equity securities. Of the $294 million of exited investment commitments, 94% were floating rate, 3% were fixed rate, 2% were non-interest bearing and 1% were on non-accrual status. The weighted average yield of debt and other income producing securities exited or repaid during the period at amortized cost was 9.4%. On the $294 million of investment commitments exited from October 1, 2013 through November 30, 2013, we recognized total net realized gains of approximately $26 million.

              In addition, as of November 30, 2013, we had an investment backlog and pipeline of approximately $785 million and $470 million, respectively. Investment backlog includes transactions approved by our investment adviser's investment committee and/or for which a formal mandate, letter of intent or signed commitment has been issued, and therefore we believe are likely to close. Investment pipeline includes transactions where due diligence and analysis are in process, but no formal mandate, letter of intent or signed commitment has been issued. The consummation of any of the investments in this backlog and pipeline depends upon, among other things, one or more of the following: satisfactory completion of our due diligence investigation of the prospective portfolio company, our acceptance of the terms and structure of such investment and the execution and delivery of satisfactory transaction documentation. In addition, we may syndicate a portion of these investments and certain of these investments may result in the repayment of existing investments. We cannot assure you that we will make any of these investments or that we will syndicate any portion of these investments.

Our Corporate Information

(1)

The underwriting discounts and commissions with respect to the shares sold in this offering, which is a one-time fee, is the only sales load paid in connection with this offering. Because the underwriters may offer the shares from time to time, for the purpose of calculating sales load, we have assumed the underwriters will sell the shares to the public at a price of $18.29 per share, the official close price of our common stock on The NASDAQ Global Select Market on December 9, 2013.

(2)

Amount reflects estimated offering expenses of approximately $0.6 million based on the 14,300,000 shares offered in this offering (assuming that the underwriters do not exercise their option to purchase additional shares).

(3)

The expenses of the dividend reinvestment plan are included in "Other expenses."

(4)

The "consolidated net assets attributable to common stock" used to calculate the percentages in this table is our average net assets of $4.2 billion for the nine months ended September 30, 2013.

(5)

Our management fee is currently 1.5% of our total assets (other than cash and cash equivalents, which includes assets purchased with borrowed amounts). Our management fee has been estimated by multiplying our average total assets (assuming we maintain no cash or cash equivalents) for the nine months ended September 30, 2013 by 1.5%. The 2.45% reflected on the table is higher than 1.5% because such percentage is calculated on our average net assets (rather than our average total assets) for the same period. See "Management—Investment Advisory and Management Agreement" in the accompanying prospectus.

(6)

This item represents our investment adviser's incentive fees estimated by annualizing our incentive fee related to our pre-incentive fee net investment income for the nine months

ended September 30, 2013 and annualizing our accrual in accordance with U.S. generally accepted accounting principles ("GAAP") of a capital gains incentive fee of $7.1 million for the nine months ended September 30, 2013, even though no capital gains incentive fee was actually payable under the investment advisory and management agreement for the nine months ended September 30, 2013.

GAAP requires that the capital gains incentive fee accrual consider the cumulative aggregate unrealized capital appreciation in the calculation, as a capital gains incentive fee would be payable if such unrealized capital appreciation were realized, even though such unrealized capital appreciation is not permitted to be considered in calculating the fee actually payable under the Investment Company Act or the investment advisory and management agreement. This GAAP accrual is calculated using the aggregate cumulative realized capital gains and losses and aggregate cumulative unrealized capital depreciation included in the calculation of the capital gains incentive fee actually payable under the investment advisory and management agreement (the "Capital Gains Fee") plus the aggregate cumulative unrealized capital appreciation. If such amount is positive at the end of a period, then GAAP requires us to record a capital gains incentive fee equal to 20% of such cumulative amount, less the aggregate amount of actual Capital Gains Fees paid or capital gains incentive fees accrued under GAAP in all prior periods. The resulting accrual for any capital gains incentive fee under GAAP in a given period may result in an additional expense if such cumulative amount is greater than in the prior period or a reversal of previously recorded expense if such cumulative amount is less than in the prior period. If such cumulative amount is negative, then there is no accrual. There can be no assurance that such unrealized capital appreciation will be realized in the future or that the amount accrued for will ultimately be paid.

For purposes of this table, we have assumed that these fees will be payable (in the case of the capital gains incentive fee) and that they will remain constant, although they are based on Ares Capital's performance and will not be paid unless Ares Capital achieves certain goals. We expect to invest or otherwise utilize all of the net proceeds from this offering within three months of the date of this prospectus supplement and may have capital gains and interest income that could result in the payment of an incentive fee to our investment adviser in the first year after completion of this offering. Since our initial public offering through September 30, 2013, the average quarterly incentive fee accrued (including capital gains incentive fees accrued under GAAP even though they may not be payable) has been approximately 0.75% of our weighted average net assets (3.02% on an annualized basis). For more detailed information on the calculation of our incentive fees, please see below. For more detailed information about incentive fees previously incurred by us, please see Note 3 to our consolidated financial statements for the year ended December 31, 2012 and the nine months ended September 30, 2013.

The incentive fee consists of two parts:

The first, payable quarterly in arrears, equals 20% of our pre-incentive fee net investment income (including interest that is accrued but not yet received in cash), subject to a 1.75% quarterly (7.0% annualized) hurdle rate and a "catch-up" provision measured as of the end of each calendar quarter. Under this provision, in any calendar quarter, our investment adviser receives no incentive fee until our net investment income equals the hurdle rate of 1.75% but then receives, as a "catch-up," 100% of our pre-incentive fee net investment income with respect to that portion of such pre-incentive fee net investment income, if any, that exceeds the hurdle rate but is less than 2.1875%. The effect of this provision is that, if pre-incentive fee net investment income exceeds 2.1875% in any

calendar quarter, our investment adviser will receive 20% of our pre-incentive fee net investment income as if a hurdle rate did not apply.

The second part, the Capital Gains Fee, payable annually in arrears, equals 20% of our realized capital gains on a cumulative basis from inception through the end of the year, if any, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any previously paid Capital Gains Fees.

We will defer cash payment of any incentive fee otherwise earned by our investment adviser if, during the most recent four full calendar quarter period ending on or prior to the date such payment is to be made, the sum of (a) our aggregate distributions to our stockholders and (b) our change in net assets (defined as total assets less indebtedness and before taking into account any incentive fees payable during the period) is less than 7.0% of our net assets (defined as total assets less indebtedness) at the beginning of such period.

These calculations will be adjusted for any share issuances or repurchases.

See "Management—Investment Advisory and Management Agreement" in the accompanying prospectus.

"Interest payments on borrowed funds" represents our interest expenses estimated by annualizing our actual interest and credit facility expenses incurred for the nine months ended September 30, 2013. During the nine months ended September 30, 2013, our average outstanding borrowings were $2,455.3 million and cash paid for interest expense was $99.4 million. We had outstanding borrowings of $3,230.8 million (with a carrying value of $3,137.9 million) at September 30, 2013. This item is based on our assumption that our borrowings and interest costs after an offering will remain similar to those prior to such offering. The amount of leverage that we employ at any particular time will depend on, among other things, our board of directors' and our investment adviser's assessment of market and other factors at the time of any proposed borrowing. See "Risk Factors—Risks Relating to Our Business—We borrow money, which magnifies the potential for gain or loss on amounts invested and may increase the risk of investing with us" in the accompanying prospectus.

(8)

Includes our overhead expenses, including payments under our administration agreement, based on our allocable portion of overhead and other expenses incurred by Ares Operations in performing its obligations under the administration agreement, and income taxes. Such expenses are estimated by annualizing "Other expenses" for the nine months ended September 30, 2013. The holders of shares of our common stock (and not the holders of our debt securities or preferred stock, if any) indirectly bear the cost associated with our annual expenses. See "Management—Administration Agreement" in the accompanying prospectus.

(9)

The Company's stockholders indirectly bear the expenses of underlying funds or other investment vehicles that would be investment companies under section 3(a) of the Investment Company Act but for the exceptions to that definition provided for in sections 3(c)(1) and 3(c)(7) of the Investment Company Act ("Acquired Funds") in which the Company invests. This amount includes the estimated annual fees and expenses of Acquired Funds in which the Company is invested as of September 30, 2013. Certain of these Acquired Funds are subject to management fees, which generally range from 1% to 2.5% of total net assets, or incentive fees, which generally range between 15% to 25% of net profits. When applicable, fees and expenses estimates are based on historic fees and expenses for the Acquired Funds. For those Acquired Funds with little or no operating history, fees and expenses are estimates based on expected fees and expenses stated in the

Acquired Funds' offering memorandum, private placement memorandum or other similar communication without giving effect to any performance. Future fees and expenses for these Acquired Funds may be substantially higher or lower because certain fees and expenses are based on the performance of the Acquired Funds, which may fluctuate over time.

(10)

"Total annual expenses" as a percentage of consolidated net assets attributable to common stock are higher than the total annual expenses percentage would be for a company that is not leveraged. We borrow money to leverage and increase our total assets. The SEC requires that the "Total annual expenses" percentage be calculated as a percentage of net assets (defined as total assets less indebtedness and before taking into account any incentive fees payable during the period), rather than the total assets, including assets that have been funded with borrowed monies.

(1)

Assumes that we will not realize any capital gains computed net of all realized capital losses and unrealized capital depreciation.

(2)

Assumes no unrealized capital depreciation and 5% annual return resulting entirely from net realized capital gains (and therefore subject to the capital gains incentive fee). However, cash payment of the capital gains incentive fee would be deferred if, during the most recent four full calendar quarter period ending on or prior to the date the payment set forth in the example is to be made, the sum of (a) our aggregate distributions to our stockholders and (b) our change in net assets (defined as total assets less indebtedness and before taking into account any incentive fees payable during the period) was less than 7.0% of our net assets (defined as total assets less indebtedness) at the beginning of such period (as adjusted for any share issuances or repurchases).

See Note 17 to our consolidated financial statements for the year ended December 31, 2012 for more information on the Allied Acquisition.

(2)

In accordance with Accounting Standards Codification ("ASC") 260-10, the weighted average shares of common stock outstanding used in computing basic and diluted earnings per common share have been adjusted retroactively by a factor of 1.02% to recognize the bonus element associated with rights to acquire shares of common stock that we issued to stockholders of record as of March 24, 2008 in connection with a rights offering.

(3)

Includes commitments to portfolio companies for which funding had yet to occur.

(4)

Weighted average yield of debt and other income producing securities at fair value is computed as (a) the annual stated interest rate or yield earned plus the net annual amortization of original issue discount and market discount earned on accruing debt and income producing securities, divided by (b) total accruing debt and income producing securities at fair value. Weighted average yield of debt and other income producing securities at amortized cost is computed as (a) annual stated interest rate or yield earned plus the net annual amortization of original issue discount and market discount earned on accruing debt and income producing securities, divided by (b) total accruing debt and income producing securities at amortized cost.

(5)

Total return based on market value for the nine months ended September 30, 2013 equaled the decrease of the ending market value at September 30, 2013 of $17.29 per share from the ending market value at December 31, 2012 of $17.50 per share plus the declared dividends of $1.14 per share for the nine months ended September 30, 2013, divided by the market value at December 31, 2012. Total return based on market value for the nine months ended September 30, 2012 equaled the increase of the ending market value at September 30, 2012 of $17.14 per share from the ending market value at December 31, 2011 of $15.45 per share plus the declared dividends of $1.17 per share for the nine months ended September 30, 2012, divided by the market value at December 31, 2011. Total return based on market value for the year ended December 31, 2012 equaled the increase of the ending market value at December 31, 2012 of $17.50 per share from the ending market value at December 31, 2011 of $15.45 per share plus the declared dividends of $1.60 per share for the year ended December 31, 2012. Total return based on market value for the year ended December 31, 2011 equaled the decrease of the ending market value at December 30, 2011 of $15.45 per share from the ending market value at December 31, 2010 of $16.48 per share plus the declared dividends of $1.41 per share for the year ended December 31, 2011.
