		Re:		Fifth Street Finance Corp.
				Registration Statement on Form N-2 filed on April 12, 2010
				File No. 333-166012

Dear Mr. Minore:

     On behalf of Fifth Street Finance Corp. (the “Company”), set forth below are the Company’s responses to the comments provided by the staff of the Division of Investment Management (the “Staff”) of the Securities and Exchange Commission (the “SEC”) to the Company in a letter dated May 18, 2010. The Staff’s comments are set forth below in italics and are followed by the Company’s responses. References to the Company’s registration statement on Form N-2 (the “Registration Statement”) contained herein are to the pre-effective amendment No. 1 to the Company’s registration statement on Form N-2 that has been filed with the SEC on the date hereof.

Prospectus

Registration Statement

	1.		If the Company proposes an offering from this registration statement shortly after its effectiveness, it should file, as part of its next pre-effective amendment, the form of prospectus supplement that the Company intends to use with that offering.
			The Company advises the Staff that it will file a form of prospectus supplement as part of the Registration Statement in a pre-effective amendment if the Company proposes an offering from this Registration Statement shortly after its effectiveness. At this time, given the volatility of the stock market and the price of the Company’s shares of common stock, the Company cannot predict when it will propose to conduct an offering from the Registration Statement. As a result,

Mr. Dominic Minore

the Company has not included a form of prospectus supplement as part of the Registration Statement.

Prospectus

	2.		The financial information contained in the prospectus should be updated to the fiscal quarter ended March 31, 2010.
			The Company has updated the disclosure accordingly.

Prospectus Cover Page

	3.		In the sixth paragraph, provide the net asset value per share and the last reported sale price per share of the common stock of the Company as of a recent date.
			The Company advises the Staff that it has provided the net asset value per share of the Company as of March 31, 2010 and the last reported sale price per share of the common stock of the Company as of a recent date. As you are aware, business development companies (“BDCs”) have universally adopted the practice of determining the net asset value of their shares of common stock as of the end of each of their fiscal quarters. This practice reflects the reality of the significant time and expense expended by BDCs in determining the fair value of their investment portfolios, which are primarily composed of securities issued by private companies. As a result, the Company has not determined its net asset value per share since March 31, 2010. In light of the foregoing, the Company is unable to state the net asset value per share of the Company’s common stock as of a date more recent than March 31, 2010.

About this Prospectus

	4.		Expand the last sentence of the second paragraph to clarify that the prospectus and any prospectus supplements will, however, be updated during the offering period to reflect any material changes to the information contained therein.
			The Company has revised the disclosure accordingly. See page ii of the Registration Statement.

Prospectus Summary — Fifth Street Finance Corp.

5.

Disclose what the Company’s asset coverage ratio would be if the maximum amount of SBA guaranteed debt excluded pursuant to any exemptive relief is added back to the calculation of the asset coverage ratio. Also disclose the maximum amount of additional leverage that the Company could incur if the exemptive relief is granted.

The Company advises the Staff that it has not yet received any exemptive relief in connection with its SBA guaranteed debt. The Company has revised the disclosure accordingly. See page 2 of the Registration Statement.

Fees and Expenses

	6.		It appears the phrase “and a corresponding prospectus supplement” should be deleted from the third sentence.
			The Company has revised the disclosure accordingly. See page 10 of the Registration Statement.
	7.		We note the absence of the Acquired Company Fees & Expenses line item from the Company’s fee table. Please confirm to us in your response letter whether the Company will make investments that trigger the need for applicable Acquired Company Fees & Expenses disclosure or whether such expenses amount to less than one basis point and are, therefore, included in “Other expenses.”
			The Company advises the Staff that such expenses total less than one basis point of the Company’s average net assets and, as a result, such amounts are included in “Other Expenses.”
	8.		In your response letter, confirm that the Company’s investment adviser has no ability to recoup any of the base management fee that it either has or will have “permanently waived.”
			The Company confirms to the Staff that its investment adviser has no ability to recoup any of the base management fee that it has “permanently waived.”
	9.		Expand the footnote to the “Interest payments on borrowed funds” line item to highlight the estimates and assumptions underlying the 0.39% figure. In your response letter, confirm that “Interest payments on borrowed funds” is presented on a consolidated basis.
			The Company has revised the disclosure accordingly. See page 11 of the Registration Statement. The Company confirms to the Staff that “Interest payments on borrowed funds” is presented on a consolidated basis.
	10.		In a footnote to the fee table, disclose that the Company does not expect to issue preferred shares during the next twelve months.
			The Company advises the Staff that, in connection with its 2010 Annual Meeting of Stockholders, the Company’s stockholders approved a proposal to remove Fifth Street Finance Corp.’s authority to issue shares of preferred stock. As a result, the Company has no authority under its amended and restated certificate of

			incorporation to issue any preferred shares. See “Description of our Securities” on page 90 of the Registration Statement.
	11.		The first three sentence of footnote (8) should be deleted because they appear not to enhance an investor’s understanding of the “Total annual expenses” presentation.
			The Company has revised the disclosure accordingly. See page 11 of the Registration Statement.

Risk Factors

	12.		Expand the first paragraph to clarify that the risks set forth in this section nonetheless discuss the presently known principal risks of investing in the Company. In this regard, add any additional disclosure needed to complete the discussion of risks required by Item 8.3 of Form N-2.
			The Company has revised the disclosure accordingly. See page 14 of the Registration Statement.

Our wholly-owned SBIC subsidiary, Fifth Street Mezzanine Partners IV L.P. is licensed by the SBA and is subject to SBA regulations

	13.		Highlight what experience, if any, Fifth Street Mezzanine Partners IV, L.P. has managing an SBA licensed entity.

	14.		Delete the mitigating phrase “as is common in the business development company industry” from the risk factor disclosure.
			The Company has revised the disclosure accordingly. See page 18 of the Registration Statement.
	15.		Expand the discussion to indicate the percentage of the Company’s assets that are currently subject to liens or pledges. Also discuss the potential material impact, if any, that such liens or pledges may have on the Company’s operations, policies, strategies and financial flexibility.

Borrowings

	17.		We note that Wells Fargo Securities has acted as lead underwriter for each of the Company’s five offerings from its shelf registration statement since it was declared effective in July 2009. We also note the disclosure on page 48 pertaining to the current borrowing arrangement and related agreements with Wachovia, Wells Fargo Securities, LLC and Wells Fargo Bank, National Association. In your response letter, provide us with your analysis as to the applicability of Investment Company Act sections 57(d)(2) & (e) and, if those provisions are applicable, whether the transaction nevertheless meets the requirements of Investment Company Act section 57(f).
			Section 57(d) of the Investment Company Act of 1940 (the “1940 Act”) generally prohibits certain persons related to a BDC in the manner enumerated in Section 57(e) (“Related Persons”) from participating in certain types of transactions with the BDC, absent approval in the manner set forth in Section 57(f) of the 1940 Act by a majority of the BDC’s directors who have no financial interest in the transaction, plan or arrangement and a majority of the BDC’s directors who are not “interested persons” (as defined in Section 2(a)(19) of the 1940 Act) of the BDC (such approval being referred to herein as the “Independent Director Approval”). Section 57(d)(2) of the 1940 Act prohibits certain purchase transactions between a BDC and a Related Person unless Independent Director Approval has been obtained.
			Among the Related Persons enumerated in Section 57(e) is an “affiliated person”1 of a “principal underwriter” of or for a BDC. Section 2(a)(29) of the 1940 Act defines a “principal underwriter” of or for a BDC as follows:

Mr. Dominic Minore
June  , 2010
Page 6

Any underwriter who, in connection with a primary distribution of securities: (A) is in privity of contract with the issuer or an affiliated person of the issuer; (B) acting alone or in concert with one or more other persons; initiates or directs the formation of an underwriting syndicate; or (C) is allowed a rate of gross commission, spread, or other profit greater than the rate allowed another underwriter participating in the distribution. [Emphasis added.]

As a result, an “affiliated person” of a “principal underwriter” would be precluded from engaging in the purchase transactions set forth in Section 57(d)(2) of the 1940 Act with a BDC absent Independent Director Approval. Thus, if Wells Fargo Securities, LLC were deemed to be the principal underwriter of or for the Company at the time of the Company’s entry into the borrowing arrangement and related transactions with Wachovia Bank, N.A. and Wells Fargo Bank, National Association (i.e., “affiliated persons” of Wells Fargo Securities, LLC), the Company would not have been able to pledge the equity interests in its wholly-owned subsidiary, Fifth Street Funding, LLC (“Fifth Street Funding”), to Wachovia Bank, N.A. and Wells Fargo Bank, National Association in connection therewith (assuming arguendo that a pledge is tantamount to the sale of the equity interests of Fifth Street Funding by the Company and a purchase thereof by Wachovia Bank, N.A. and Wells Fargo Bank, National Association) unless the Company had obtained Independent Director Approval.

Wells Fargo Securities, LLC completed the distribution of the Company’s shares of common stock in connection with a shelf offering on October 22, 2009 and the Company had not entered into a new underwriting agreement with Wells Fargo Securities, LLC in connection with another shelf offering until January 22, 2010. Accordingly, Wells Fargo Securities, LLC was not a “principal underwriter” of the Company at the time of the Company’s entry into the pledge with Wachovia Bank, N.A. and Wells Fargo Bank, National Association on November 16, 2009.²

This result is dictated by the literal language of the “principal underwriter” definition contained in Section 2(a)(29) of the 1940 Act. As set forth above, the description of a person or entity meeting the definition of that term is worded in the present tense, “any underwriter who . . . is in privity of contract with the issuer or . . . initiates or directs . . . or . . . is allowed . . . .” (Emphasis added.)

The plain meaning of the foregoing language leads to the conclusion that a person is a principal underwriter only while the covered activities are being engaged in,

Mr. Dominic Minore
June  , 2010
Page 7

but not once those activities are completed. Indeed, a contrary conclusion would seem to produce the incongruous result that a person or entity who at one time acts as a principal underwriter for a BDC but subsequently has no dealings of any kind with the BDC would be precluded from entering into transactions with the BDC even if those transactions were to take place, for example, twenty years after the underwriting took place. As a result, we do not believe that Sections 57(d)(2) and 57(e) of the 1940 Act apply to the pledge that the Company entered into with Wachovia Bank, N.A. and Wells Fargo Bank, National Association because Wells Fargo Securities, LLC was not a “principal underwriter” of or for the Company at the time thereof.

Although not necessary for the resolution of the issue in light of the foregoing discussion, the Company represents that the pledge that it entered into with Wachovia Bank, N.A. and Wells Fargo Bank, National Association is a standard and customary feature of borrowing arrangements, did not involve any overreaching of the Company by either of them and was made on terms that were commercially reasonable to the Company. We are aware of at least 13 BDCs other than the Company that have entered or intend to enter into pledge agreements in connection with their borrowing arrangements. Moreover, in light of current economic conditions, many banks and other lenders may not be willing to extend credit to BDCs or other entities on an unsecured basis. Thus, because the pledge that the Company entered into with Wachovia Bank, N.A. and Wells Fargo Bank, National Association is a standard and customary feature of borrowing arrangements, did not involve any overreaching of the Company by either of them and was made on terms that were commercially reasonable to the Company, we believe the policy behind the limitations set forth in Section 57 of the 1940 Act (i.e., the prevention of the overreaching of BDCs by their affiliates) is not implicated by the pledge that the Company entered into with Wachovia Bank, N.A. and Wells Fargo Bank, National Association.

In addition, the Company advises the Staff that on May 27, 2010, it entered into a three-year secured syndicated revolving credit facility led by ING Capital LLC. An affiliate of each of Morgan Stanley & Co. Incorporated, UBS Securities LLC and RBC Capital Markets Corporation is a lender party to the ING facility and each of Morgan Stanley & Co. Incorporated, UBS Securities LLC and RBC Capital Markets Corporation may serve as an underwriter for future securities offerings by the Company pursuant to the Registration Statement. The Company represents that the pledge that it entered into as part of the ING facility is a standard and customary feature of borrowing arrangements and did not involve any overreaching of the Company by the entities set forth above or their affiliates and was made on terms that were commercially reasonable to the Company. As discussed above with respect to Wells Fargo, at the time the pledge was entered into, none of the entities set forth above or their affiliates was an underwriter of the Company’s securities or in privity of contract with the Company.
