(1)In the event that our securities are sold to or through underwriters, a corresponding prospectus supplement will disclose the applicable sales load.

(2)In the event that we conduct an offering of our securities, a corresponding prospectus supplement will disclose the estimated offering expenses.

(3)The expenses of administering our DRIP are included in operating expenses. The DRIP does not allow shareholders to sell shares through the DRIP. If a shareholder wishes to sell shares they would be required to select a broker of their choice and pay any fees or other costs associated with the sale.

(5)Operating expenses in this table represent the estimated annual operating expenses of CSWC and its consolidated subsidiaries based on annualized operating expenses for the quarter ended June 30, 2024. We do not have an investment adviser and are internally managed by our executive officers under the supervision of the Board. As a result, we do not pay investment advisory fees, but instead we pay the operating costs associated with employing investment management professionals including, without limitation, compensation expenses related to salaries, discretionary bonuses and restricted stock grants.

(6)Interest payments on borrowed funds represents (a) our estimated annual interest payments based on actual interest rate terms under our credit facilities, with available commitments of $485 million under the Company’s senior secured revolving credit facility (the “Corporate Credit Facility”) and available commitments of $200 million under the Company’s special purpose vehicle financing credit facility (the “SPV Credit Facility”), and our anticipated drawdowns from our credit facilities, (b) our actual interest rate terms under the SBA Debentures and our anticipated drawdowns of the SBA Debentures, and (c) our estimated annual interest payments, based on actual interest rate terms, on the 4.50% Notes due 2026 (the “January 2026 Notes”), the 3.375% Notes due 2026 (the “October 2026 Notes”) and the 7.75% Notes due 2028 (the “August 2028 Notes”). As of June 30, 2024, we had $165.0 million outstanding under the Corporate Credit Facility, $64.0 million outstanding under the SPV Credit Facility, $153.0 million outstanding under the SBA Debentures, $140.0 million in aggregate principal of the January 2026 Notes outstanding, $150.0 million in aggregate principal of the October 2026 Notes outstanding and $71.9 million in aggregate principal of the August 2028 Notes outstanding. Any future issuances of debt securities will be made at the discretion of management and the Board of directors after evaluating the investment opportunities and economic situation of the Company and the market as a whole.

(7)Income tax provision/(benefit) relates to the accrual of (a) deferred and current tax provision/(benefit) for U.S. federal income taxes and (b) excise, state and other taxes. Deferred taxes are non-cash in nature and may vary significantly from period to period. We are required to include deferred taxes in calculating our annual expenses even though deferred taxes are not currently payable or receivable. Income tax provision/(benefit) represents the estimated annual income tax provision/(benefit) of CSWC and its consolidated subsidiaries based on annualized income tax provision/(benefit) for the quarter ended June 30, 2024.

Expense Example [Table Text Block]

Example

The following example demonstrates the projected dollar amount of total cumulative expenses that would be incurred over various periods with respect to a hypothetical investment in our common stock. In calculating the following expense amounts, we have assumed we would have no additional leverage and that our annual operating expenses would remain at the levels set forth in the table above. In the event that shares to which this prospectus relates are sold to or through underwriters, a corresponding prospectus supplement will restate this example to reflect the applicable sales load.

You would pay the following expenses on a $1,000 investment, assuming 5.0% annual return	$	138	$	380	$	590	$	997

The example and the expenses in the table above should not be considered a representation of our future expenses, and actual expenses may be greater or less than those shown. While the example assumes, as required by the SEC, a 5.0% annual return, our performance will vary and may result in a return greater or less than 5.0%. In addition, while the example assumes reinvestment of all dividends at NAV, participants in our DRIP will receive a number of shares of our common stock, determined by dividing the total dollar amount of the dividend payable to a participant by the average purchase price of all shares of common stock purchased by the administrator of the DRIP in the event that shares are purchased in the open market to satisfy the share requirements of the DRIP, which may be at, above or below NAV. See “Dividend Reinvestment Plan” for additional information regarding our DRIP.

Purpose of Fee Table , Note [Text Block]

The following table is intended to assist you in understanding the costs and expenses that an investor in an offering will bear directly or indirectly. We caution you that some of the percentages indicated in the table below are estimates and may vary. Except where the context suggests otherwise, whenever this prospectus contains a reference to fees or expenses paid by “you,” “us” or “CSWC,” or that “we” will pay fees or expenses, shareholders will indirectly bear such fees or expenses as investors in us.

Other Transaction Fees, Note [Text Block]

The expenses of administering our DRIP are included in operating expenses. The DRIP does not allow shareholders to sell shares through the DRIP. If a shareholder wishes to sell shares they would be required to select a broker of their choice and pay any fees or other costs associated with the sale.

Other Expenses, Note [Text Block]

Operating expenses in this table represent the estimated annual operating expenses of CSWC and its consolidated subsidiaries based on annualized operating expenses for the quarter ended June 30, 2024. We do not have an investment adviser and are internally managed by our executive officers under the supervision of the Board. As a result, we do not pay investment advisory fees, but instead we pay the operating costs associated with employing investment management professionals including, without limitation, compensation expenses related to salaries, discretionary bonuses and restricted stock grants.

General Description of Registrant [Abstract]

Investment Objectives and Practices [Text Block]

We specialize in providing customized debt and equity financing to LMM companies in a broad range of investment segments located primarily in the United States. Our investment objective is to produce attractive risk-adjusted returns by generating current income from our debt investments and capital appreciation from our equity and equity related investments. Our investment strategy is to partner with business owners, management teams and financial sponsors to provide flexible financing solutions to fund growth, changes of control, or other corporate events. We invest primarily in first lien debt securities, secured by security interests in portfolio company assets. We also may invest in equity interests in our portfolio companies alongside our debt securities.

We focus on investing in companies with histories of generating revenues and positive cash flow, established market positions and proven management teams with strong operating discipline. Our core business is to target senior debt investments and equity investments in LMM companies. Our target companies generally have annual earnings before interest, taxes, depreciation and amortization (“EBITDA”) between $3.0 million and $25.0 million, and our investments generally range in size from $5.0 million to $50.0 million.

We seek to fill the financing gap for LMM companies, which historically have had more limited access to financing from commercial banks and other traditional sources. The underserved nature of the LMM creates the opportunity for us to meet the financing needs of LMM companies while also negotiating favorable transaction terms and equity participation. Our ability to invest across a LMM company’s capital structure, from secured loans to equity securities, allows us to offer portfolio companies a comprehensive suite of financing options. Providing customized financing solutions is important to LMM companies. We generally seek to partner directly with financial sponsors, entrepreneurs, management teams and business owners in making our investments. Our LMM debt investments typically include senior loans with a first lien on the assets of the portfolio company. Our LMM debt investments typically have a term of up to five years from the original investment date. We also often seek to invest in the equity securities of our LMM portfolio companies.

We specialize in providing customized debt and equity financing to lower middle market (“LMM”) companies in a broad range of investment segments located primarily in the United States. Our investment objective is to produce attractive risk-adjusted returns by generating current income from our debt investments and capital appreciation from our equity and equity related investments. Our investment strategy is to partner with business owners, management teams and financial sponsors to provide flexible financing solutions to fund growth, changes of control, or other corporate events. We invest primarily in senior debt securities, secured by security interests in portfolio company assets. We also may invest in equity interests in our portfolio companies alongside our debt securities.

Our target companies generally have annual earnings before interest, taxes, depreciation and amortization between $3.0 million and $25.0 million, and our investments generally range in size from $5.0 million to $50.0 million.

Risk Factors [Table Text Block]

SUPPLEMENTARY RISK FACTORS

Investing in the Notes involves a high degree of risk. Before you invest in the Notes, you should be aware of various significant risks, including those described below. Before you decide whether to make an investment in the Notes, you should carefully consider these risks, together with all of the risks and uncertainties described in the section titled “Risk Factors” in the accompanying prospectus, our most recent Annual Report on Form 10-K and our most recent Quarterly Report on Form 10-Q, as well as in subsequent filings with the SEC, which are incorporated by reference into this prospectus supplement and the accompanying prospectus in their entirety, and other information in this prospectus supplement, the accompanying prospectus, the documents incorporated by reference in this prospectus supplement and the accompanying prospectus, and any free writing prospectus that we may authorize for use in connection with this offering. The risks set forth below are not the only risks we face. If any of the following risks occur, our business, financial condition and results of our operations could be materially adversely affected. In such case, you could lose all or part of your investment. Please also read carefully the section titled “Special Note Regarding Forward-Looking Statements” in this prospectus supplement.

Risks Related to the Notes

The Notes will be unsecured and therefore will be effectively subordinated to any existing and future secured indebtedness, including indebtedness under the Corporate Credit Facility.

The Notes will not be secured by any of our assets or any of the assets of any of our subsidiaries. As a result, the Notes will be effectively subordinated to any existing and future secured indebtedness we or our subsidiaries have outstanding as of the date of this prospectus supplement (including the Corporate Credit Facility) or that we or our subsidiaries may incur in the future (or any indebtedness that is initially unsecured as to which we subsequently grant a security interest) to the extent of the value of the assets securing such indebtedness. In any liquidation, dissolution, bankruptcy or other similar proceeding, the holders of any of our secured indebtedness or secured indebtedness of our subsidiaries may assert rights against the assets pledged to secure that indebtedness in order to receive full payment of their indebtedness before the assets may be used to pay other creditors, including the holders of the Notes. As of September 9, 2026, we had $351.0 million in outstanding indebtedness under the Corporate Credit Facility, which is secured by (1) all of the present and future property and assets of the Company and the guarantors and (2) 100.0% of the equity interests in the Company’s wholly owned subsidiaries (except for the assets held by the SBIC Subsidiaries and SPV).

The Notes will be structurally subordinated to the indebtedness and other liabilities of our subsidiaries, including the SBA Debentures and the SPV Credit Facility.

The Notes will be obligations exclusively of Capital Southwest, and not of any of our subsidiaries. None of our subsidiaries will be a guarantor of the Notes, and the Notes will not be required to be guaranteed by any subsidiary we may acquire or create in the future. Any assets of our subsidiaries will not be directly available to satisfy the claims of our creditors, including holders of the Notes. Except to the extent we are a creditor with recognized claims against our subsidiaries, all claims of creditors of our subsidiaries will have priority over our equity interests in such entities (and therefore the claims of our creditors, including holders of the Notes) with respect to the assets of such entities. Even if we are recognized as a creditor of one or more of our subsidiaries, our claims would still be effectively subordinated to any security interests in the assets of any such subsidiary and to any indebtedness or other liabilities of any such subsidiary senior to our claims. Consequently, the Notes will be structurally subordinated to all indebtedness and other liabilities, including trade payables, of any of our existing or future subsidiaries (including the SBA Debentures and the SPV Credit Facility). As of September 9, 2026, we had $281.0 million in SBA Debentures outstanding, and $151.0 million outstanding indebtedness under the SPV Credit Facility, which is secured by all of SPV’s assets. The SBIC Subsidiaries, SPV and any future subsidiaries of the Company may incur substantial indebtedness in the future, all of which would be structurally senior to the Notes.

The indenture under which the Notes will be issued contains limited protection for holders of the Notes.

The indenture under which the Notes will be issued offers limited protection to holders of the Notes. The terms of the indenture and the Notes will not restrict our or any of our subsidiaries’ ability to engage in, or otherwise be a party to, a variety of corporate transactions, circumstances or events that could have a material adverse impact on your investment in the Notes. In particular, the terms of the indenture and the Notes will not place any restrictions on our or our subsidiaries’ ability to:

•issue securities or otherwise incur additional indebtedness or other obligations, including (1) any indebtedness or other obligations that would be equal in right of payment to the Notes, (2) any indebtedness or other obligations that would be secured and therefore rank effectively senior in right of payment to the Notes to the extent of the value of the assets securing such indebtedness, (3) indebtedness or other obligations of ours that are guaranteed by one or more of our subsidiaries and which therefore is structurally senior to the Notes and (4) securities, indebtedness or other obligations

issued or incurred by our subsidiaries that would be senior to our equity interests in our subsidiaries and therefore rank structurally senior to the Notes with respect to the assets of our subsidiaries, in each case, other than an incurrence of indebtedness or other obligations that would cause a violation of Section 18(a)(1)(A) as modified by Section 61(a)(2) of the 1940 Act or any successor provisions, whether or not we continue to be subject to such provisions of the 1940 Act, but giving effect, in each case, to any exemptive relief granted to us by the SEC. Currently, these provisions generally prohibit us from incurring additional borrowings, including through the issuance of additional debt securities, unless our asset coverage, as defined in the 1940 Act, equals at least 150% after such borrowings;

•pay dividends on, or purchase or redeem or make any payments in respect of, capital stock or other securities ranking junior in right of payment to the Notes, including subordinated indebtedness, except that we have agreed that, for the period of time during which the Notes are outstanding, we will not violate Section 18(a)(1)(B) as modified by (i) Section 61(a)(2) of the 1940 Act or any successor provisions and after giving effect to any exemptive relief granted to us by the SEC and (ii) the following two exceptions: (A) we will be permitted to declare a cash dividend or distribution notwithstanding the prohibition contained in Section 18(a)(1)(B) as modified by Section 61(a)(2) of the 1940 Act or any successor provisions, but only up to such amount as is necessary for us to maintain our status as a RIC under subchapter M of the Code; and (B) this restriction will not be triggered unless and until such time as our asset coverage has not been in compliance with the minimum asset coverage required by Section 18(a)(1)(B) as modified by Section 61(a)(2) of the 1940 Act or any successor provisions (after giving effect to any exemptive relief granted to us by the SEC) for more than six consecutive months. If Section 18(a)(1)(B) as modified by Section 61(a)(2) of the 1940 Act were currently applicable to us in connection with this offering, these provisions would generally prohibit us from declaring any cash dividend or distribution upon any class of our capital stock, or purchasing any such capital stock if our asset coverage, as defined in the 1940 Act, were below 150% at the time of the declaration of the dividend or distribution or the purchase and after deducting the amount of such dividend, distribution or purchase;

•sell assets (other than certain limited restrictions on our ability to consolidate, merge or sell all or substantially all of our assets);

•enter into transactions with affiliates;

•create liens (including liens on the shares of our subsidiaries) or enter into sale and leaseback transactions;

•make investments; or

•create restrictions on the payment of dividends or other amounts to us from our subsidiaries.

Furthermore, the terms of the indenture and the Notes will not protect holders of the Notes in the event that we experience changes (including significant adverse changes) in our financial condition, results of operations or credit ratings, as they will not require that we or our subsidiaries adhere to any financial tests or ratios or specified levels of net worth, revenues, income, cash flow, or liquidity other than as described under “Description of the Notes — Events of Default”.

Our ability to recapitalize, incur additional debt (including additional debt that matures prior to the maturity of the Notes), and take a number of other actions that are not limited by the terms of the Notes may have important consequences for you as a holder of the Notes, including making it more difficult for us to satisfy our obligations with respect to the Notes or negatively affecting the market value of the Notes.

Other debt we issue or incur in the future could contain more protections for its holders than the indenture and the Notes, including additional covenants and events of default. The issuance or incurrence of any such debt with incremental protections could affect the market for, trading levels, and prices of the Notes.

The optional redemption provision may materially adversely affect your return on the Notes.

The Notes are redeemable in whole or in part upon certain conditions at any time or from time to time at our option. We may choose to redeem the Notes at times when prevailing interest rates are lower than the interest rate paid on the Notes. In this circumstance, you may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the Notes being redeemed.

We may not be able to repurchase the Notes upon a Change of Control Repurchase Event.

Upon a Change of Control Repurchase Event, holders of the Notes may require us to repurchase for cash some or all of the Notes at a repurchase price equal to 100% of the aggregate principal amount of the Notes being repurchased, plus accrued and

unpaid interest to, but not including, the repurchase date. We may not be able to repurchase the Notes upon a Change of Control Repurchase Event because we may not have sufficient funds. Before making any such repurchase of Notes, we would also have to comply with certain requirements under the Corporate Credit Facility, to the extent such requirements remain in effect at such time, or otherwise obtain consent from the lenders under the Corporate Credit Facility. The terms of the Corporate Credit Facility and the SPV Credit Facility also provide that certain change of control events will constitute an event of default thereunder entitling the respective lenders to accelerate any indebtedness outstanding under such credit facilities at that time and to terminate such credit facilities. In addition, the occurrence of a Change of Control Repurchase Event enabling the holders of the Notes to require the mandatory purchase of the Notes would likely constitute an event of default under the Corporate Credit Facility, entitling the lenders under the Corporate Credit Facility to accelerate any indebtedness outstanding under the Corporate Credit Facility at that time and to terminate the Corporate Credit Facility. Our or our subsidiaries' future financing arrangements may contain similar restrictions and provisions. Our failure to purchase such tendered Notes upon the occurrence of such Change of Control Repurchase Event would cause an event of default under the indenture governing the Notes and a cross-default under the agreements governing certain of our other indebtedness, including under the agreements governing the Corporate Credit Facility, the indenture governing the 2029 Convertible Notes, the indenture governing the 2030 Notes, and likely under the agreements governing the SPV Credit Facility, which may result in the acceleration of such indebtedness requiring us to repay such indebtedness immediately. If the holders of the Notes or the 2030 Notes exercise their respective right to require us to repurchase any Notes or any 2030 Notes, respectively, upon a Change of Control Repurchase Event (as defined in the relevant indenture), the financial effect of any such repurchase could cause a default under our current and future debt instruments, even if the Change of Control Repurchase Event itself would not cause a default. If a Change of Control Repurchase Event were to occur, we may not have sufficient funds to repay any such accelerated indebtedness. See “Description of the Notes - Offer to Repurchase Upon a Change of Control Repurchase Event” in this prospectus supplement for more information.

There is no active trading market for the Notes. If an active trading market does not develop for the Notes, you may not be able to sell them.

The Notes are a new issue of debt securities for which there currently is no trading market. We do not intend to apply for listing the Notes on any securities exchange or for quotation of the Notes on any automated dealer quotation system. If no active trading market develops, you may not be able to sell the Notes at their fair market value or at all. If the Notes are traded after their initial issuance, they may trade at a discount to their initial offering price depending on prevailing interest rates, the market for similar securities, our credit ratings, our financial condition, performance and prospects, general economic conditions, or other relevant factors. The underwriters are not obligated to make a market in the Notes and any such market-making may be discontinued at any time in the sole discretion of the underwriters without any notice. Accordingly, we cannot assure you that a liquid trading market will develop for the Notes, that you will be able to sell your Notes at a particular time or that the price you receive when you sell will be favorable. To the extent an active trading market does not develop, the liquidity and trading price for the Notes may be adversely affected. Accordingly, you may be required to bear the financial risk of an investment in the Notes for an indefinite period of time.

Our amount of debt outstanding will increase as a result of this offering, and if we default on our obligations to pay our other indebtedness, we may not be able to make payments on the Notes.

Any default under the agreements governing our indebtedness, including a default under the Corporate Credit Facility, the SPV Credit Facility, the indenture governing the 2029 Convertible Notes, the indenture governing the 2030 Notes, or other indebtedness to which we may be a party that is not waived by the required lenders or holders, and the remedies sought by the lenders or the holders of such indebtedness could make us unable to pay principal, premium, if any, and interest on the Notes and substantially decrease the market value of the Notes. If we are unable to generate sufficient cash flow and are otherwise unable to obtain funds necessary to meet required payments of principal, premium, if any, and interest on our indebtedness, or if we otherwise fail to comply with the various covenants, including financial and operating covenants, as applicable, in the instruments governing our indebtedness (including the Corporate Credit Facility, the SPV Credit Facility, the 2029 Convertible Notes, and the 2030 Notes), we could be in default under the terms of the agreements governing such indebtedness, including the Notes. In the event of such default, the holders of such indebtedness could elect to declare all the funds borrowed thereunder to be due and payable, together with accrued and unpaid interest, the lenders under the Corporate Credit Facility, the SPV Credit Facility, or other debt we may incur in the future could elect to terminate their commitment, cease making further loans and institute foreclosure proceedings against our assets, and we could be forced into bankruptcy or liquidation.

Our ability to generate sufficient cash flow in the future is, to some extent, subject to general economic, financial, competitive, legislative and regulatory factors as well as other factors that are beyond our control. We cannot assure you that our business will generate cash flow from operations, or that future borrowings will be available to us under the Corporate Credit Facility, the SPV Credit Facility, or otherwise, in an amount sufficient to enable us to meet our payment obligations under the Notes, the 2029 Convertible Notes, the 2030 Notes, our other debt, and to fund other liquidity needs.

If our operating performance declines and we are not able to generate sufficient cash flow to service our debt obligations, we may, in the future, need to refinance or restructure our debt, including any Notes sold, sell assets, reduce or delay capital investments, seek to raise additional capital or seek to obtain waivers from the lenders under the Corporate Credit Facility, the SPV Credit Facility, the holders of the 2029 Convertible Notes, the holders of the 2030 Notes, or other debt that we may incur in the future to avoid being in default. If we are unable to implement one or more of these alternatives, we may not be able to meet our payment obligations under the Notes and our other debt. If we breach our covenants under the Corporate Credit Facility, the SPV Credit Facility, the 2029 Convertible Notes, the 2030 Notes, or any of our other debt and seek a waiver, we may not be able to obtain a waiver from the required lenders or holders thereof. If this occurs, we would be in default under the Corporate Credit Facility, the SPV Credit Facility, the 2029 Convertible Notes, the 2030 Notes, or other debt, the lenders or holders could exercise rights as described above, and we could be forced into bankruptcy or liquidation. If we are unable to repay debt, lenders having secured obligations could proceed against the collateral securing the debt. Because each of the Corporate Credit Facility, the SPV Credit Facility, and the indentures governing the 2029 Convertible Notes and the 2030 Notes have and the indenture governing the Notes will have, and any future credit facilities will likely have, customary cross-default provisions, if the indebtedness under the Notes, the 2029 Convertible Notes, the 2030 Notes, the Corporate Credit Facility, the SPV Credit Facility, or under any future credit facility is accelerated, we may be unable to repay or finance the amounts due.

A downgrade, suspension or withdrawal of the credit rating assigned by a rating agency to us or the Notes or change in the debt markets could cause the liquidity or market value of the Notes to decline significantly.

Our credit ratings are an assessment by rating agencies of our ability to pay our debts when due. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of the Notes. These credit ratings may not reflect the potential impact of risks relating to the structure or marketing of the Notes. Credit ratings are not a recommendation to buy, sell or hold any security, and may be revised or withdrawn at any time by the issuing organization in its sole discretion. Neither we nor any underwriter undertakes any obligation to maintain our credit ratings or to advise holders of Notes of any changes in our credit ratings. There can be no assurance that our credit ratings will remain for any given period of time or that such credit ratings will not be lowered or withdrawn entirely by the rating agencies if in their judgment future circumstances relating to the basis of the credit ratings, such as adverse changes in the Company, so warrant. The conditions of the financial markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future, which could have an adverse effect on the market prices of the Notes.

As of September 9, 2026, the total amount of indebtedness outstanding under the Corporate Credit Facility was $351.0 million. We intend to use the net proceeds from this offering to repay a portion of the outstanding indebtedness under the Corporate Credit Facility. After giving effect to this offering and such repayments, we expect to have approximately $8.9 million of outstanding indebtedness under the Corporate Credit Facility. This table has not been adjusted to reflect the changes in our outstanding borrowings subsequent to June 30, 2026.

DESCRIPTION OF THE NOTES

The Notes will be issued under a base indenture, dated October 23, 2017, and an eighth supplemental indenture thereto, to be entered into between us and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee. We refer to the base indenture and the eighth supplemental indenture collectively as the “indenture” and to U.S. Bank Trust Company, National Association as the “trustee.”

The Notes will be governed by the indenture, as required by federal law for all bonds and notes of companies that are publicly offered. An indenture is a contract between us and the financial institution acting as trustee on your behalf, and is subject to and governed by the Trust Indenture Act of 1939, as amended. The trustee has two main roles. First, the trustee can enforce your rights against us if we default. There are some limitations on the extent to which the trustee acts on your behalf, described in the second paragraph under “— Events of Default — Remedies if an Event of Default Occurs” below. Second, the trustee performs certain administrative duties for us with respect to the Notes.

This section includes a summary description of the material terms of the Notes and the indenture. Because this section is a summary, however, it does not describe every aspect of the Notes and the indenture. We urge you to read the indenture because it, and not this description, defines your rights as a holder of the Notes. The base indenture has been included as an exhibit to the registration statement of which this prospectus supplement is a part and the eighth supplemental indenture will be filed as an exhibit to a current report on Form 8-K, in each case, as filed or as will be filed with the SEC. See “Available Information” in this prospectus supplement for information on how to obtain a copy of the indenture.

General

The Notes will mature on September 15, 2031. The principal payable at maturity will be 100% of the aggregate principal amount. The interest rate of the Notes is 6.750% per year and will be paid semi-annually in arrears on March 15 and September 15 of each year, beginning March 15, 2027, and the regular record dates for interest payments will be every March 1 and September 1, beginning March 1, 2027.

The initial interest period will be the period from and including September 15, 2026, to, but excluding, the initial interest payment date, and the subsequent interest periods will be the periods from and including an interest payment date to, but excluding, the next interest payment date or the stated maturity date, as the case may be. Interest on the Notes will be computed

on the basis of a 360-day year composed of twelve 30-day months.

If an interest payment date falls on a non-business day, the applicable interest payment will be made on the next business day and no additional interest will accrue as a result of such delayed payment. The term “business day” means, with respect to any Note, each Monday, Tuesday, Wednesday, Thursday, and Friday that is not a day on which banking institutions in The City of New York or the corporate trust office of the trustee are authorized or obligated by law or executive order to close.

We will issue the Notes in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The Notes will not be subject to any sinking fund.

The indenture does not limit the amount of debt (including secured debt) that may be issued by us or our subsidiaries under the indenture or otherwise, but does contain a covenant regarding our asset coverage that would have to be satisfied at the time of our incurrence of additional indebtedness. See “— Other Covenants” and “— Events of Default.” Other than the foregoing and as described under “— Other Covenants” and “— Events of Default” below, the indenture does not contain any financial covenants or restrict us from paying dividends or issuing or repurchasing our other securities. Other than restrictions described under “— Offer to Repurchase Upon a Change of Control Repurchase Event” and “— Merger, Consolidation or Asset Sale” below, the indenture does not contain any covenants or other provisions designed to afford holders of the Notes protection in the event of a highly leveraged transaction involving us or if our credit rating declines as the result of a takeover, recapitalization, highly leveraged transaction or similar restructuring involving us that could adversely affect your investment in the Notes.

We may, without the consent of the holders of the Notes, issue additional notes under the indenture with the same terms (except for the issue date, offering price, and, if applicable, the initial interest payment date) and with the same CUSIP numbers as the Notes offered hereby in an unlimited aggregate principal amount, subject to the terms of the Corporate Credit Facility and the SPV Credit Facility, and any other financing agreements to which we may be party; provided that such additional notes must be treated as part of the same issue as the Notes offered hereby for U.S. federal income tax purposes. In addition, we have the ability to issue indenture securities with terms different from the Notes.

We do not intend to list the Notes on any securities exchange or automated dealer quotation system.

Optional Redemption

Prior to the Par Call Date, we may redeem the Notes at our option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of the principal amount and rounded to three decimal places) equal to the greater of:

•(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 35 basis points less (b) interest accrued to the date of redemption, and

•(2) 100% of the principal amount of the Notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to, but not including, the redemption date.

On or after the Par Call Date, we may redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to, but not including, the redemption date.

For purposes of calculating the redemption price in connection with the redemption of the Notes, on any redemption date, the following terms have the meanings set forth below:

“Par Call Date” means August 15, 2031 (one month prior to the maturity date of the Notes).

“Treasury Rate” means, with respect to any redemption date of the Notes, the yield determined by us in accordance with the following two paragraphs.

The Treasury Rate shall be determined by us after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) — H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities — Treasury constant maturities — Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, we shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields — one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life — and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 or any successor designation or publication is no longer published, we shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, we shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, we shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security

shall be based upon the average of the bid and asked prices (expressed as a percentage of the principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

Our actions and determinations in determining the redemption price of any of the Notes shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of notes to be redeemed (with a copy to the trustee).

In the case of a partial redemption, selection of the Notes for redemption will be made in compliance with the requirements of DTC, or if the Notes are not then held through DTC, or DTC prescribed no method of selection, then selection of the Notes for redemption will be made pro rata, by lot or by such other method as the trustee in its sole discretion deems appropriate and fair. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the holder of the Note upon surrender for cancellation of the original Note. For so long as the notes are held by DTC (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary.

Unless the Company defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the notes or portions thereof called for redemption.

Offer to Repurchase Upon a Change of Control Repurchase Event

If a Change of Control Repurchase Event occurs, unless we have exercised our right to redeem the Notes in full, we will make an offer to each holder of the Notes to repurchase all or any part (in minimum denominations of $2,000 and integral multiples of $1,000 principal amount in excess thereof) of that holder's Notes at a repurchase price in cash equal to 100% of the aggregate principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to, but not including, the date of repurchase. Within 30 days following any Change of Control Repurchase Event or, at our option, prior to any Change of Control, but after the public announcement of the Change of Control, we will mail a notice to each holder (with a copy to the trustee) describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase Notes on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice. We will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Notes, we will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict.

On the Change of Control Repurchase Event payment date, subject to extension if necessary to comply with the provisions of the 1940 Act, we will, to the extent lawful:

(1) accept for payment all Notes or portions of Notes properly tendered pursuant to our offer;

(2) deposit with the paying agent an amount equal to the aggregate purchase price in respect of all Notes or portions of Notes properly tendered; and

(3) deliver or cause to be delivered to the trustee the Notes properly accepted, together with an officers' certificate stating the aggregate principal amount of Notes being purchased by us.

The paying agent will promptly remit to each holder of Notes properly tendered the purchase price for the Notes, and, upon written instruction from Capital Southwest, the trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each holder a new Note equal in principal amount to any unpurchased portion of any Notes surrendered; provided that each new Note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

We will not be required to make an offer to repurchase the Notes upon a Change of Control Repurchase Event if a third party makes an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by us and such third party purchases all Notes properly tendered and not withdrawn under its offer.

The source of funds that will be required to repurchase Notes in the event of a Change of Control Repurchase Event will be our available cash or cash generated from our operations or other potential sources, including funds provided by a purchaser in the Change of Control transaction, borrowings, sales of assets or sales of equity. We cannot assure you that sufficient funds from such sources will be available at the time of any Change of Control Repurchase Event to make required repurchases of Notes tendered. Before making any such repurchase of Notes, we also would have to comply with certain requirements under the Corporate Credit Facility, to the extent such requirements remain in effect at such time, or otherwise obtain consent from the lenders under the Corporate Credit Facility. The terms of the Corporate Credit Facility and the SPV Credit Facility also provide that certain change of control events will constitute an event of default thereunder entitling the respective lenders to accelerate any indebtedness outstanding under such credit facilities at that time and to terminate such credit facilities. In addition, the occurrence of a Change of Control Repurchase Event enabling the holders of the Notes to require the mandatory purchase of the Notes would likely constitute an event of default under the Corporate Credit Facility, entitling the lenders under the Corporate Credit Facility to accelerate any indebtedness outstanding under the Corporate Credit Facility at that time and to terminate the Corporate Credit Facility. Our or our subsidiaries’ future financing arrangements may contain similar restrictions and provisions. Our failure to purchase such tendered Notes upon the occurrence of such Change of Control Repurchase Event would cause an event of default under the indenture governing the Notes and a cross-default under the agreements governing certain of our other indebtedness, including under the agreements governing the Corporate Credit Facility, the indenture governing the 2029 Convertible Notes, the indenture governing the 2030 Notes, and likely under the agreements governing the SPV Credit Facility, which may result in the acceleration of such indebtedness requiring us to repay such indebtedness immediately. If the holders of the Notes or the 2030 Notes exercise their respective right to require us to repurchase any Notes or any 2030 Notes, respectively, upon a Change of Control Repurchase Event (as defined in the relevant indenture), the financial effect of any such repurchase could cause a default under our current and future debt instruments, even if the Change of Control Repurchase Event itself would not cause a default. If a Change of Control Repurchase Event were to occur, we may not have sufficient funds to repay any such accelerated indebtedness.

The definition of “Change of Control” includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of our properties or assets and those of our Controlled Subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise, established definition of the phrase under applicable law. Accordingly, the ability of a holder of Notes to require us to repurchase the Notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of our assets and the assets of our Controlled Subsidiaries taken as a whole to another person or group may be uncertain.

For purposes of the Notes:

“Below Investment Grade Rating Event” means the Notes are downgraded below Investment Grade by both Rating Agencies on any date from the date of the public notice of an arrangement that results in a Change of Control until the end of the 60-day period following public notice of the occurrence of a Change of Control (which period shall be extended so long as the rating of the Notes is under publicly announced consideration for possible downgrade by either of the Rating Agencies); provided that a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Repurchase Event hereunder) if the Rating Agencies do not announce or publicly confirm or inform the trustee in writing at the Company's request (acting at the written direction of the holders of a majority of principal amount of the outstanding Notes) that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Rating Event).

“Change of Control” means the occurrence of any of the following:

(1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation) in one or a series of related transactions, of all or substantially all of the assets of Capital Southwest and its Controlled Subsidiaries taken as a whole to any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act), other than to any Permitted Holders; provided that, for the avoidance of doubt, a pledge of assets pursuant to any secured debt instrument of Capital Southwest or its Controlled Subsidiaries shall not be deemed to be any such sale, lease, transfer, conveyance or disposition;

(2) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) (other than any Permitted Holders) becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the outstanding Voting Stock of Capital Southwest, measured by voting power rather than number of shares; or

(3) the approval by Capital Southwest's stockholders of any plan or proposal relating to the liquidation or dissolution of Capital Southwest.

“Change of Control Repurchase Event” means the occurrence of a Change of Control and a Below Investment Grade Rating Event.

“Controlled Subsidiary” means any subsidiary of Capital Southwest, 50% or more of the outstanding equity interests of which are owned by Capital Southwest and its direct or indirect subsidiaries and of which Capital Southwest possesses, directly or indirectly, the power to direct or cause the direction of the management or policies, whether through the ownership of voting equity interests, by agreement or otherwise.

“Fitch” means Fitch Ratings, Inc., also known as Fitch Ratings, or any successor thereof.

“Investment Grade” means a rating of BBB- or better by Fitch (or its equivalent under any successor rating categories of Fitch) and Baa3 by Moody’s (or its equivalent under any successor rating categories of Moody’s) (or, in any case, if such Rating Agency ceases to rate the Notes for reasons outside of our control, the equivalent investment grade credit rating from any Rating Agency selected by us as a replacement Rating Agency).

“Moody’s” means Moody’s Investors Service, Inc., or any successor thereof.

“Permitted Holders” means (i) us and (ii) one or more of our Controlled Subsidiaries.

“Rating Agency” means:

(1)each of Fitch and Moody’s; and

(2)if any of Fitch or Moody’s ceases to rate the Notes or fails to make a rating of the Notes publicly available for reasons outside of our control, a “nationally recognized statistical rating organization” as defined in Section (3)(a)(62) of the Exchange Act selected by us as a replacement agency for Fitch or Moody’s, or both, as the case may be.

“Voting Stock” as applied to stock of any person, means shares, interests, participations or other equivalents in the equity interest (however designated) in such person having ordinary voting power for the election of a majority of the directors (or the equivalent) of such person, other than shares, interests, participations or other equivalents having such power only by reason of the occurrence of a contingency.

Global Securities

Each Note will be issued in book-entry form and represented by a global security that we deposit with and register in the name of DTC or its nominee. A global security may not be transferred to or registered in the name of anyone other than the depositary or its nominee, unless special termination situations arise. As a result of these arrangements, the depositary, or its nominee, will be the sole registered owner and holder of all the Notes represented by a global security, and investors will be permitted to own only beneficial interests in a global security. For more information about these arrangements, see “— Book-Entry Procedures” below.

Termination of a Global Security

If a global security is terminated for any reason, interests in it will be exchanged for certificates in non-book-entry form (certificated securities). After that exchange, the choice of whether to hold the certificated Notes directly or in street name will be up to the investor. Investors must consult their own banks or brokers to find out how to have their interests in a global security transferred on termination to their own names, so that they will be holders.

Payment and Paying Agents

We will pay interest to the person listed in the trustee’s records as the owner of the Notes at the close of business on a particular day in advance of each due date for interest, even if that person no longer owns the Note on the interest due date. That day, usually about two weeks in advance of the interest due date, is called the “record date.” Because we will pay all the interest for an interest period to the holders on the record date, holders buying and selling the Notes must work out between themselves the appropriate purchase price. The most common manner is to adjust the sales price of the Notes to prorate interest fairly between buyer and seller based on their respective ownership periods within the particular interest period. This prorated interest amount is called “accrued interest.”

Payments on Global Securities

We will make payments on the Notes so long as they are represented by a global security in accordance with the applicable policies of the depositary as in effect from time to time. Under those policies, we will make payments directly to the depositary, or its nominee, and not to any indirect holders who own beneficial interests in the global security. An indirect holder’s right to those payments will be governed by the rules and practices of the depositary and its participants, as described under “— Book-Entry Procedures” below.

Payments on Certificated Securities

In the event the Notes become represented by certificated securities, we will make payments on the Notes as follows. We will pay interest that is due on an interest payment date to the holder of the Notes as shown on the trustee’s records as of the close of business on the regular record date. We will make all payments of principal and premium, if any, by check at the designated office of the trustee in New York, New York and/or at other offices that may be specified in the indenture or a notice to holders against surrender of the Note.

Alternatively, if the holder asks us to do so, we will pay any amount that becomes due on the debt security by wire transfer of immediately available funds to an account at a bank in New York City, on the due date. To request payment by wire, the holder must give the applicable trustee or other paying agent appropriate transfer instructions at least 15 business days before the requested wire payment is due. In the case of any interest payment due on an interest payment date, the instructions must be given by the person who is the holder on the relevant regular record date. Any wire instructions, once properly given, will remain in effect unless and until new instructions are given in the manner described above.

Payment When Offices Are Closed

If any payment is due on the Notes on a day that is not a business day, we will make the payment on the next day that is a business day. Payments made on the next business day in this situation will be treated under the indenture as if they were made on the original due date. Such payment will not result in a default under the Notes or the indenture, and no interest will accrue on the payment amount from the original due date to the next day that is a business day.

Book-entry and other indirect holders should consult their banks or brokers for information on how they will receive payments on the Notes.

Events of Default

You will have rights if an Event of Default occurs in respect of the Notes and the Event of Default is not cured, as described later in this subsection.

The term “Event of Default” in respect of the Notes means any of the following:

•we do not pay the principal of, or any premium on, any Note when due and payable at maturity;

•we do not pay interest on any Note when due and payable, and such default is not cured within 30 days of its due date;

•we remain in breach of any other covenant in respect of the Notes for 60 days after we receive a written notice of default stating we are in breach (the notice must be sent by either the trustee or holders of at least 25% of the principal amount of the outstanding Notes);

•we file for bankruptcy or certain other events of bankruptcy, insolvency or reorganization occur and remain undischarged or unstayed for a period of 60 days;

•on the last business day of each of twenty-four consecutive calendar months, the Notes have an asset coverage of less than 100%, giving effect to any exemptive relief granted to us by the SEC; or

•default by us or any of our significant subsidiaries, as defined in Article 1, Rule 1-02 of Regulation S-X promulgated under the Exchange Act (but excluding any subsidiary which is (a) a non-recourse or limited recourse subsidiary, (b) a bankruptcy remote special purpose vehicle, or (c) is not consolidated with Capital Southwest for purposes of U.S. GAAP), with respect to any mortgage, agreement or other instrument under which there may be outstanding, or by which there may be secured or evidenced, any indebtedness for money borrowed in excess of $50 million in the aggregate of us and/ or any such subsidiary, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable or (ii) constituting a failure to pay the principal or interest of any such debt when due and payable at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise, unless, in either case, such indebtedness is discharged, or such acceleration is rescinded, stayed or annulled, within a period of 30 calendar days after written notice of such failure is given to us by the trustee or to us and the trustee by the holders of at least 25% in aggregate principal amount of the Notes then outstanding.

An Event of Default for the Notes may, but does not necessarily, constitute an Event of Default for any other series of debt securities issued under the same or any other indenture. Within 90 days after the occurrence of any default or Event of Default under the indenture with respect to the Notes and if a responsible officer of the trustee has received written notice or has actual knowledge of such event, the trustee shall transmit notice to the holders of such default known to the trustee, unless such default shall have been cured or waived; provided, however, that, except in the case of a default in the payment of the principal of (or premium, if any, on) or interest, if any, on any Note, the trustee shall be protected in withholding such notice if and so long as the trustee in good faith determines that withholding of such notice is in the interest of the holders of the Notes; and provided further that in the case of any default or breach specified in the third bullet point above with respect to the Notes, no such notice shall be given until at least 60 days after the occurrence thereof.

Remedies if an Event of Default Occurs

If an Event of Default has occurred and is continuing, the trustee or the holders of not less than 25% in principal amount of the Notes may declare the entire principal amount of all the Notes to be due and immediately payable, but this does not entitle any holder of Notes to any redemption payout or redemption premium. If an Event of Default referred to in the third to last bullet point above with respect to us has occurred, the entire principal amount of all of the Notes will automatically become due and immediately payable, without any action on the part of the trustee. This is called a declaration of acceleration of maturity. In certain circumstances, a declaration of acceleration of maturity may be canceled by the holders of a majority in principal amount of the Notes if (1) we have deposited with the trustee all amounts due and owing with respect to the Notes (other than principal or any payment that has become due solely by reason of such acceleration) and certain other amounts, and (2) any other Events of Default have been cured or waived.

Except in cases of default, where the trustee has some special duties, the trustee is not required to take any action under the indenture at the request of any holders unless the holders offer the trustee protection from expenses and liability satisfactory to it (called an “indemnity”). If indemnity satisfactory to the trustee is provided, the holders of a majority in principal amount of the Notes may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. However, the trustee may refuse to follow any direction that conflicts with law or the indenture, that may involve the trustee in personal liability, or if it is not provided with security and/or indemnity reasonably satisfactory to the trustee and may take any other action it deems proper that is not inconsistent with any such direction received from holders. In addition, the trustee will not be required to expend its own funds under any circumstances. No delay or omission in exercising any right or remedy will be treated as a waiver of that right, remedy or Event of Default.

Before you are allowed to bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the Notes, the following must occur:

•you must give the trustee written notice that an Event of Default has occurred and remains uncured;

•the holders of at least 25% in principal amount of all the Notes must make a written request that the trustee take action because of the default and must offer (and, if requested, provide) security and/or indemnity reasonably satisfactory to the trustee against the cost and other liabilities of taking that action;

•the trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity; and

•the holders of a majority in principal amount of the Notes must not have given the trustee a direction inconsistent with the above notice during that 60-day period.

However, you are entitled at any time to bring a lawsuit for the payment of money due on your Notes on or after the due date.

Book-entry and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to declare or cancel an acceleration of maturity.

Each year, we will furnish to the trustee a written statement of certain of our officers certifying that to their knowledge we are in compliance with the indenture and the Notes, or else specifying any default.

Waiver of Default

The holders of a majority in principal amount of the Notes may waive any past defaults other than a default:

•in the payment of principal (or premium, if any) or interest; or

•in respect of a covenant that cannot be modified or amended without the consent of each holder of the Notes.

Merger, Consolidation or Asset Sale

Under the terms of the indenture, we are generally permitted to consolidate or merge with another entity. We are also permitted to sell all or substantially all of our assets to another entity. However, we may not take any of these actions unless all the following conditions are met where:

•we merge out of existence or convey or transfer all or substantially all of our assets, the resulting entity must agree to be legally responsible for our obligations under the Notes;

•the merger or sale of assets must not cause a default on the Notes and we must not already be in default (unless the merger or sale would cure the default). For purposes of this no-default test, a default would include an Event of Default that has occurred and has not been cured, as described under “Events of Default” above. A default for this purpose would also include any event that would be an Event of Default if the requirements for giving us a notice of default or our default having to exist for a specific period of time were disregarded; and

•we must deliver certain certificates and documents to the trustee.

Notwithstanding any of the foregoing and subject to the 1940 Act, any subsidiary of ours may consolidate with, merge into or transfer all or part of its property and assets to other subsidiaries of ours or to us. Additionally, this covenant shall not apply to: (1) our merger or the merger of one of our subsidiaries with an affiliate solely for the purpose of reincorporating in another jurisdiction; (2) any conversion by us or a subsidiary from an entity formed under the laws of one state to any entity formed under the laws of another state; or (3) any combination of (1) and (2) above.

Although there is a limited body of case law interpreting the phrase “substantially all”, there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve “all or substantially all” of the properties or assets of a person. As a result, it may be unclear as to whether the merger, consolidation or sale of assets covenant would apply to a particular transaction as described above absent a decision by a court of competent jurisdiction. Although these types of transactions are permitted under the indenture, certain of the foregoing transactions could constitute a Change of Control that results in a Change of Control Repurchase Event permitting each holder to require us to repurchase the Notes of such holder as described above.

An assumption by any person of obligations under the Notes and the indenture might be deemed for U.S. federal income tax purposes to be an exchange of the Notes for new Notes by the holders thereof, resulting in recognition of gain or loss for such purposes and possibly other adverse tax consequences to the holders. Holders should consult their own tax advisors regarding the tax consequences of such an assumption.

Modification or Waiver

There are three types of changes we can make to the indenture and the Notes issued thereunder.

Changes Requiring Your Approval

First, there are changes that we cannot make to your Notes without your specific approval. The following is a list of those types of changes:

•change the stated maturity of the principal of (or premium, if any, on) or any installment of principal of or interest on the Notes;

•reduce any amounts due on the Notes or reduce the rate of interest on the Notes;

•reduce the amount of principal payable upon acceleration of the maturity of a Note following a default;

•change the place or currency of payment on a Note;

•impair your right to sue for payment;

•reduce the percentage of holders of Notes whose consent is needed to modify or amend the indenture; and

•reduce the percentage of holders of Notes whose consent is needed to waive compliance with certain provisions of the indenture or to waive certain defaults or reduce the percentage of holders of Notes required to satisfy quorum or voting requirements at a meeting of holders of the Notes.

Changes Not Requiring Approval

The second type of change does not require any vote by the holders of the Notes. This type is limited to clarifications and certain other changes that would not adversely affect holders of the Notes in any material respect.

Changes Requiring Majority Approval

Any other change to the indenture and the Notes would require the following approval:

•if the change affects only the Notes, it must be approved by the holders of a majority in principal amount of the Notes; and

•if the change affects more than one series of debt securities issued under the same indenture, it must be approved by the holders of a majority in principal amount of all of the series affected by the change, with all affected series voting together as one class for this purpose.

In each case, the required approval must be given by written consent.

The holders of a majority in principal amount of all of the series of debt securities issued under an indenture, voting together as one class for this purpose, may waive our compliance with some of our covenants in that indenture. However, we cannot obtain a waiver of a payment default or of any of the matters covered by the bullet points included above under “— Changes Requiring Your Approval.”

Further Details Concerning Voting

When taking a vote, we will use the following rules to decide how much principal to attribute to the Notes:

The Notes will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust money for their payment or redemption or if we or any affiliate of ours own any Notes. The Notes will also not be eligible to vote if they have been fully defeased as described later under “— Defeasance — Full Defeasance” below.

We generally will be entitled to set any day as a record date for the purpose of determining the holders of the Notes that are entitled to vote or take other action under the indenture. However, the record date may not be earlier than 30 days before the date of the first solicitation of holders to vote on or take such action and not later than the date such solicitation is completed. If we set a record date for a vote or other action to be taken by holders of the Notes, that vote or action may be taken only by persons who are holders of the Notes on the record date and must be taken within eleven months following the record date.

Book-entry and other indirect holders should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the indenture or the Notes or request a waiver.

Satisfaction and Discharge

The indenture will be discharged and will cease to be of further effect with respect to the Notes when:

•Either

•all the Notes that have been authenticated have been delivered to the trustee for cancellation; or

•all the Notes that have not been delivered to the trustee for cancellation:

•have become due and payable, or

•will become due and payable at their stated maturity within one year, or

•are to be called for redemption,

and we, in the case of the first, second and third sub-bullets above, have irrevocably deposited or caused to be deposited with the trustee as trust funds in trust solely for the benefit of the holders of the Notes, in amounts in the currency payable for the Notes as will be sufficient, to pay and discharge the entire indebtedness (including all principal, premium, if any, and interest) on such Notes delivered to the trustee for cancellation (in the case of Notes that have become due and payable on or prior to the date of such deposit) or to the stated maturity or redemption date, as the case may be;

•we have paid or caused to be paid all other sums payable by us under the indenture with respect to the Notes; and

•we have delivered to the trustee an officers’ certificate and legal opinion, each stating that all conditions precedent provided for in the indenture relating to the satisfaction and discharge of the indenture and the Notes have been complied with.

Defeasance

The following provisions will be applicable to the Notes. “Defeasance” means that, by depositing with a trustee an amount of cash and/or government securities sufficient to pay all principal and interest, if any, on the Notes when due and satisfying any additional conditions noted below, we will be deemed to have been discharged from our obligations under the Notes. In the event of a “covenant defeasance,” upon depositing such funds and satisfying similar conditions discussed below we would be released from certain covenants under the indenture relating to the Notes.

Covenant Defeasance

Under current U.S. federal income tax law and the indenture, we can make the deposit described below and be released from some of the restrictive covenants in the indenture under which the Notes were issued. This is called “covenant defeasance.” In that event, you would lose the protection of those restrictive covenants but would gain the protection of having money and government securities set aside in trust to repay your Notes. In order to achieve covenant defeasance, the following must occur:

•because the Notes are denominated in U.S. dollars, we must deposit in trust for the benefit of all holders of the Notes a combination of cash and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the Notes on their various due dates;

•we must deliver to the trustee a legal opinion of our counsel confirming that, under current U.S. federal income tax law, we may make the above deposit without causing you to be taxed on the Notes any differently than if we did not make the deposit;

•we must deliver to the trustee a legal opinion of our counsel stating that the above deposit does not require registration by us under the 1940 Act, and a legal opinion and officers’ certificate stating that all conditions precedent to covenant defeasance have been complied with;

•defeasance must not result in a breach or violation of, or result in a default under, the indenture or any of our other material agreements or instruments; and

•no default or Event of Default with respect to the Notes shall have occurred and be continuing and no defaults or events of default related to bankruptcy, insolvency or reorganization shall occur during the next 90 days.

If we accomplish covenant defeasance, you can still look to us for repayment of the Notes if there were a shortfall in the trust deposit or the trustee is prevented from making payment. In fact, if one of the remaining Events of Default occurred (such as our bankruptcy) and the Notes became immediately due and payable, there might be a shortfall. Depending on the event causing the default, you may not be able to obtain payment of the shortfall.

Full Defeasance

If there is a change in U.S. federal income tax law, as described below, we can legally release ourselves from all payment and other obligations on the Notes (called “full defeasance”) if we put in place the following other arrangements for you to be repaid:

•since the Notes are denominated in U.S. dollars, we must deposit in trust for the benefit of all holders of the Notes a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the Notes on their various due dates;

•we must deliver to the trustee a legal opinion confirming that there has been a change in current U.S. federal tax law or an Internal Revenue Service (“IRS”) ruling that allows us to make the above deposit without causing you to be taxed on the Notes any differently than if we did not make the deposit;

•defeasance must not result in a breach or violation of, or constitute a default under, the indenture or any of our other material agreements or instruments; and

If we ever did accomplish full defeasance, as described above, you would have to rely solely on the trust deposit for repayment of the Notes. You could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever became bankrupt or insolvent.

Other Covenants

In addition to any other covenants described in this prospectus supplement and the accompanying prospectus, as well as standard covenants relating to payment of principal and interest, maintaining an office where payments may be made or securities can be surrendered for payment, payment of taxes by the Company and related matters, the following covenants apply to the Notes:

•We agree that for the period of time during which the Notes are outstanding, we will not violate Section 18(a)(1)(A) as modified by Section 61(a)(2) of the 1940 Act or any successor provisions, whether or not we continue to be subject to such provisions of the 1940 Act, but giving effect, in either case, to any exemptive relief granted to us by the SEC. Currently, these provisions generally prohibit us from incurring additional borrowings, including through the issuance of additional debt securities, unless our asset coverage, as defined in the 1940 Act, equals at least 150% after such borrowings.

•We agree that, for the period of time during which the Notes are outstanding, we will not violate Section 18(a)(1)(B) as modified by (i) Section 61(a)(2) of the 1940 Act or any successor provisions and after giving effect to any exemptive relief granted to us by the SEC and (ii) the two other exceptions set forth below. These statutory provisions of the 1940 Act are not currently applicable to us and will not be applicable to us as a result of this offering. However, if Section 18(a)(1)(B) as modified by Section 61(a)(2) of the 1940 Act were currently applicable to us in connection with this offering, these provisions would generally prohibit us from declaring any cash dividend or distribution upon any class of our capital stock, or purchasing any such capital stock if our asset coverage, as defined in the 1940 Act,

were below 150% at the time of the declaration of the dividend or distribution or the purchase and after deducting the amount of such dividend, distribution, or purchase. Under the covenant, we will be permitted to declare a cash dividend or distribution notwithstanding the prohibition contained in Section 18(a)(1)(B) as modified by Section 61(a)(2) of the 1940 Act or any successor provisions, but only up to such amount as is necessary for us to maintain our status as a RIC under subchapter M of the Code. Furthermore, the covenant will not be triggered unless and until such time as our asset coverage has not been in compliance with the minimum asset coverage required by Section 18(a)(1)(B) as modified by Section 61(a)(2) of the 1940 Act or any successor provisions (after giving effect to any exemptive relief granted to us by the SEC) for more than six consecutive months.

•If, at any time, we are not subject to the reporting requirements of Sections 13 or 15(d) of the Exchange Act to file any periodic reports with the SEC, we agree to furnish to holders of the Notes and the trustee, for the period of time during which the Notes are outstanding, our audited annual consolidated financial statements, within 90 days of our fiscal year end, and unaudited interim consolidated financial statements, within 45 days of our fiscal quarter end (other than our fourth fiscal quarter). All such financial statements will be prepared, in all material respects, in accordance with applicable U.S. GAAP.

Form, Exchange and Transfer of Certificated Registered Securities

If registered Notes cease to be issued in book-entry form, they will be issued:

•only in fully registered certificated form;

•without interest coupons; and

•unless we indicate otherwise, in denominations of $2,000 and amounts that are multiples of $1,000.

Holders may exchange their certificated securities for Notes of smaller denominations or combined into fewer Notes of larger denominations, as long as the total principal amount is not changed and as long as the denomination is equal to or greater than $2,000.

Holders may exchange or transfer their certificated securities at the designated office of the trustee. We have appointed the trustee to act as our agent for registering Notes in the names of holders transferring Notes. We may appoint another entity to perform these functions or perform them ourselves.

Holders will not be required to pay a service charge to transfer or exchange their certificated securities, but they may be required to pay any tax or other governmental charge associated with the transfer or exchange. The transfer or exchange will be made only if our transfer agent is satisfied with the holder’s proof of legal ownership.

We may appoint additional transfer agents or cancel the appointment of any particular transfer agent. We may also approve a change in the office through which any transfer agent acts.

If any certificated securities of a particular series are redeemable and we redeem less than all the Notes, we and the trustee may block the transfer or exchange of those Notes selected for redemption during the period beginning 15 days before the day we mail the notice of redemption and ending on the day of that mailing, in order to freeze the list of holders to prepare the mailing. We may also refuse to register transfers or exchanges of any certificated Notes selected for redemption, except that we will continue to permit transfers and exchanges of the unredeemed portion of any Note that will be partially redeemed.

If registered Notes are issued in book-entry form, only the depositary will be entitled to transfer and exchange the Notes as described in this subsection, since it will be the sole holder of the Notes.

Resignation of Trustee

The trustee may resign or be removed with respect to the Notes provided that a successor trustee is appointed to act with respect to the Notes. In the event that two or more persons are acting as trustee with respect to different series of indenture securities under the indenture, each of the trustees will be a trustee of a trust separate and apart from the trust administered by any other trustee.

Indenture Provisions - Ranking

The Notes will be our direct unsecured obligations and will rank:

•pari passu with our existing and future unsubordinated unsecured indebtedness, including, without limitation, the 2029 Convertible Notes and the 2030 Notes;

•senior to any of our future indebtedness that expressly provides it is subordinated to the Notes;

•effectively subordinated to all of our existing and future secured indebtedness (including indebtedness that is initially unsecured to which we subsequently grant security), to the extent of the value of the assets securing such indebtedness, including, without limitation, borrowings under the Corporate Credit Facility; and

•structurally subordinated to all existing and future indebtedness and other obligations of any of our subsidiaries, including, without limitation, borrowings under the SPV Credit Facility and the SBA Debentures.

Book-Entry Procedures

The Notes will be represented by global securities that will be deposited and registered in the name of DTC or its nominee. This means that, except in limited circumstances, you will not receive certificates for the Notes. Beneficial interests in the Notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may elect to hold interests in the Notes through either DTC in the United States, or Clearstream Banking, société anonyme (“Clearstream”), or Euroclear Bank S.A./N.V., as operator of the Euroclear System in Europe (“Euroclear”), if they are participants of those systems, or indirectly through organizations that are participants in those systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers' securities accounts in Clearstream’s and Euroclear’s names on the books of their respective depositories, which in turn will hold such interests in customers’ securities accounts in the depositories’ names on the books of DTC.

The Notes will be issued as fully registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. One fully registered certificate will be issued for each issuance of the Notes, in the aggregate principal amount thereof, and will be deposited with DTC. Interests in the Notes will trade in DTC’s Same Day Funds Settlement System, and any permitted secondary market trading activity in such Notes will, therefore, be required by DTC to be settled in immediately available funds. None of the Company, the trustee or the paying agent will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity, corporate and municipal debt issues, and money market instruments from over 100 countries that DTC’s participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”).

DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). DTC has a Standard & Poor’s Ratings Services’ rating of AA+. The DTC Rules applicable to its participants are on file with the SEC. More information about DTC can be found at www.dtcc.com and www.dtc.org.

Purchases of the Notes under the DTC system must be made by or through Direct Participants, which will receive a credit for the Notes on DTC’s records. The ownership interest of each actual purchaser of each security, or the “Beneficial Owner,” is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the Notes are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates

representing their ownership interests in the Notes, except in the event that use of the book-entry system for the Notes is discontinued.

To facilitate subsequent transfers, all Notes deposited by Direct Participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co. or such other name as may be requested by an authorized representative of DTC. The deposit of the Notes with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Notes; DTC’s records reflect only the identity of the Direct Participants to whose accounts the Notes are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Redemption notices shall be sent to DTC. If less than all of the Notes within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.

Redemption proceeds, distributions, and interest payments on the Notes will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct Participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us or the trustee on the payment date in accordance with their respective holdings shown on DTC’s records. Payments by participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such Participant and not of DTC nor its nominee, the trustee, or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds, distributions, and interest payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of us or the trustee, but disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect Participants.

DTC may discontinue providing its services as securities depository with respect to the Notes at any time by giving reasonable notice to us or to the trustee. Under such circumstances, in the event that a successor securities depository is not obtained, certificates are required to be printed and delivered. We may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository). In that event, certificates will be printed and delivered to DTC.

Similar to DTC, Euroclear and Clearstream hold securities for participating organizations. They also facilitate the clearance and settlement of securities transactions between their respective participants through electronic book-entry changes in the accounts of such participants. Euroclear and Clearstream provide various services to their participants, including the safekeeping, administration, clearance, settlement, lending and borrowing of internationally traded securities. Euroclear and Clearstream interface with domestic securities markets. Euroclear and Clearstream participants are financial institutions such as underwriters, securities brokers and dealers, banks, trust companies and certain other organizations. Indirect access to Euroclear and Clearstream is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Euroclear and Clearstream participant, either directly or indirectly.

Distributions with respect to notes held beneficially through Euroclear or Clearstream will be credited to the cash accounts of participants in Euroclear or Clearstream, as the case may be, in accordance with their respective procedures, to the extent received by the common depositary for Euroclear or Clearstream.

The information in this section concerning DTC, Euroclear and Clearstream has been obtained from sources that we believe to be reliable, but neither we nor the trustee or any of the underwriters take any responsibility for the accuracy thereof.

Global Clearance and Settlement Procedures

Interests in the Notes will trade in DTC’s Same Day Funds Settlement System, and any permitted secondary market trading activity in such Notes will, therefore, be required by DTC to be settled in immediately available funds. Secondary market trading between Clearstream participants and Euroclear participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional Eurobonds in immediately available funds. None of the Company, the trustee or the paying agent will have any

DESCRIPTION OF OUR DEBT SECURITIES

We may issue debt securities in one or more series. The specific terms of each series of debt securities will be described in the particular prospectus supplement relating to that series. The prospectus supplement may or may not modify the general terms found in this prospectus and will be filed with the SEC. We urge you to read the applicable prospectus supplement and any free writing prospectus that we may authorize to be provided to you related to the series of debt securities being offered, as well as the complete indentures that contain the terms of the debt securities.

As required by U.S. federal law for all bonds and notes of companies that are publicly offered, the debt securities are governed by a document called an “indenture.” An indenture is a contract between us and a financial institution acting as trustee on your behalf, and is subject to and governed by the Trust Indenture Act of 1939, as amended. The trustee has two main roles. First, the trustee can enforce your rights against us if we default. There are some limitations on the extent to which the trustee acts on your behalf, described in the second paragraph under “Events of Default-Remedies if an Event of Default Occurs.” Second, the trustee performs certain administrative duties for us with respect to the debt securities.

This section includes a description of the material provisions of the indenture. Because this section is a summary, however, it does not describe every aspect of the debt securities and the indenture. We urge you to read the indenture because it, and not this description, defines your rights as a holder of debt securities. A copy of the indenture is attached as an exhibit to the registration statement of which this prospectus is a part. We urge you to read the indenture, including any supplemental indenture applicable to the debt securities, because it, and not this description, defines rights of a holder of debt securities. See “Available Information” for information on how to obtain a copy of the indenture.

The prospectus supplement, which will accompany this prospectus, will describe the particular series of debt securities being offered by including, among other things:

•the designation or title of the series of debt securities;

•the total principal amount of the series of debt securities;

•the percentage of the principal amount at which the series of debt securities will be offered;

•the date or dates on which principal will be payable;

•the rate or rates (which may be either fixed or variable) and/or the method of determining such rate or rates of interest, if any;

•the date or dates from which any interest will accrue, or the method of determining such date or dates, and the date or dates on which any interest will be payable;

•whether any interest may be paid by issuing additional securities of the same series in lieu of cash (and the terms upon which any such interest may be paid by issuing additional securities);

•the terms for redemption, extension or early repayment, if any;

•the currencies in which the series of debt securities are issued and payable;

•whether the amount of payments of principal, premium or interest, if any, on a series of debt securities will be determined with reference to an index, formula or other method (which could be based on one or more currencies, commodities, equity indices or other indices) and how these amounts will be determined;

•the place or places of payment, transfer, conversion and/or exchange of the debt securities;

•the denominations in which the offered debt securities will be issued (if other than $2,000 and integral multiple of $1,000 thereof);

•the provision for any sinking fund;

•any restrictive covenants;

•any events of default;

•whether the series of debt securities are issuable in certificated form;

•any provisions for defeasance, covenant defeasance or discharge;

•any special U.S. federal income tax implications, including, if applicable, U.S. federal income tax considerations relating to original issue discount;

•whether and under what circumstances we will pay additional amounts in respect of any tax, assessment or governmental charge and, if so, whether we will have the option to redeem the debt securities rather than pay the additional amounts (and the terms of this option);

•any provisions for convertibility or exchangeability of the debt securities into or for any other securities;

•whether the debt securities are subject to subordination and the terms of such subordination;

•whether the debt securities are secured and the terms of any security interests;

•the listing, if any, on a securities exchange; and

•any other terms.

The debt securities may be secured or unsecured obligations. Under the provisions of the 1940 Act, we are permitted, as a BDC, to issue debt only in amounts such that our asset coverage, as defined in the 1940 Act, equals at least 150% after each issuance of debt. In accordance with the 1940 Act, on April 25, 2018, the Board unanimously approved the application of the modified asset coverage requirements set forth in Section 61(a)(2) of the 1940 Act. As a result, the minimum asset coverage ratio applicable to the Company was decreased from 200% to 150%, which became effective on April 25, 2019. The Board also approved a resolution that limits the Company’s issuance of senior securities such that the asset coverage ratio, taking into account such issuance, would not be less than 166%, at any time after the effective date. For a discussion of the risks involved with incurring additional leverage, see “Risk Factors” in our annual, quarterly and other reports filed with the SEC from time to time. Unless the prospectus supplement states otherwise, principal (and premium, if any) and interest, if any, will be paid by us in immediately available funds.

General

The indenture provides that any debt securities proposed to be sold under this prospectus and the accompanying prospectus supplement (“offered debt securities”) may be issued under the indenture in one or more series.

For purposes of this prospectus, any reference to the payment of principal of or premium or interest, if any, on debt securities will include additional amounts if required by the terms of the debt securities.

The indenture does not limit the amount of debt securities that may be issued thereunder from time to time. Debt securities issued under the indenture, when a single trustee is acting for all debt securities issued under the indenture, are called the “indenture securities”. The indenture also provides that there may be more than one trustee thereunder, each with respect to one or more different series of indenture securities. See “Resignation of Trustee” below. At a time when two or more trustees are acting under the indenture, each with respect to only certain series, the term “indenture securities” means the one or more series of debt securities with respect to which each respective trustee is acting. In the event that there is more than one trustee under the indenture, the powers and trust obligations of each trustee described in this prospectus will extend only to the one or more series of indenture securities for which it is trustee. If two or more trustees are acting under the indenture, then the indenture securities for which each trustee is acting would be treated as if issued under separate indentures.

Except as described under “ – Merger or Consolidation” below, the indenture does not contain any provisions that give you protection in the event we issue a large amount of debt or we are acquired by another entity.

We refer you to the applicable prospectus supplement for information with respect to any deletions from, modifications of or additions to the Events of Default or our covenants that are described below, including any addition of a covenant or other provision providing event risk protection or similar protection.

We have the ability to issue indenture securities with terms different from those of indenture securities previously issued and, without the consent of the holders thereof, to reopen a previous issue of a series of indenture securities and issue additional indenture securities of that series unless the reopening was restricted when that series was created.

We expect that we will usually issue debt securities in book entry only form represented by global securities and will specify the method of issuance in the applicable prospectus supplement.

Conversion and Exchange

If any debt securities are convertible into or exchangeable for other securities, the prospectus supplement will explain the terms and conditions of the conversion or exchange, including the conversion price or exchange ratio (or the calculation method), the conversion or exchange period (or how the period will be determined), if conversion or exchange will be mandatory or at the option of the holder or us, provisions for adjusting the conversion price or the exchange ratio and provisions affecting conversion or exchange in the event of the redemption of the underlying debt securities. These terms also may include provisions under which the number or amount of other securities to be received by the holders of the debt securities upon conversion or exchange would be calculated according to the market price of the other securities as of a time stated in the prospectus supplement.

Payment

Unless otherwise specified in the prospectus supplement, we will pay interest to the person listed in the trustee’s records as the owner of the debt security at the close of business on a particular day in advance of each due date for interest, even if that person no longer owns the debt security on the interest due date. That day, usually about two weeks in advance of the interest due date, is called the “record date.” Because we will pay all the interest for an interest period to the holders on the record date, holders buying and selling the debt securities must work out between themselves the appropriate purchase price. The most

common manner is to adjust the sales price of the debt securities to prorate interest fairly between buyer and seller based on their respective ownership periods within the particular interest period. This prorated interest amount is called “accrued interest.”

Payments on Global Securities

We will make payments on a global security in accordance with the applicable policies of the depositary as in effect from time to time. Under those policies, we will make payments directly to the depositary, or its nominee, and not to any indirect holders who own beneficial interests in the global security. An indirect holder’s right to those payments will be governed by the rules and practices of the depositary and its participants.

Payment When Offices Are Closed

If any payment is due on a debt security on a day that is not a business day, we will make the payment on the next day that is a business day. Payments made on the next business day in this situation will be treated under the indenture as if they were made on the original due date, except as otherwise indicated in the attached prospectus supplement. Such payment will not result in a default under any debt security or the indenture, and no interest will accrue on the payment amount from the original due date to the next day that is a business day.

Book-entry and other indirect holders should consult their banks or brokers for information on how they will receive payments on their debt securities.

Events of Default

You will have rights if an Event of Default occurs in respect of the debt securities of your series and is not cured, as described later in this subsection.

The term “Event of Default” in respect of the debt securities of your series means any of the following (unless the applicable prospectus supplement or supplemental indenture relating to such debt securities states otherwise):

•we do not pay the principal of, or any premium on, a debt security of the series on its due date;

•we do not pay interest on a debt security of the series within 30 days of its due date;

•we do not deposit any sinking fund payment in respect of debt securities of the series within 2 business days of its due date;

•we remain in breach of a covenant in respect of debt securities of the series for 60 days after we receive a written notice of default stating we are in breach. The notice must be sent by either the trustee or holders of at least 25% of the principal amount of debt securities of the series;

•we file for bankruptcy or certain other events of bankruptcy, insolvency or reorganization occur and, in the case of certain orders or decrees entered against us under any bankruptcy law, such order or decree remains undischarged or unstayed for a period of 60 days;

•any series of debt securities issued under the indenture has an asset coverage, as such term is defined in the 1940 Act, of less than 100 per centum on the last business day of each of twenty-four consecutive calendar months; giving effect to any exemptive relief granted to us by the SEC; or

•any other Event of Default in respect of debt securities of the series described in the prospectus supplement occurs.

An Event of Default for a particular series of debt securities does not necessarily constitute an Event of Default for any other series of debt securities issued under the same or any other indenture. The trustee may withhold notice to the holders of debt securities of any default, except in the payment of principal, premium, interest or sinking or purchase fund installment, if it in good faith considers the withholding of notice to be in the interest of the holders.

Remedies if an Event of Default Occurs

Unless the prospectus supplement specifies otherwise, if an Event of Default has occurred and has not been cured, the trustee or the holders of at least 25% in principal amount of the outstanding debt securities of the affected series may (and the trustee shall at the request of such holders) declare the entire principal amount of all the debt securities of that series to be due and immediately payable, but does not entitle any holder to any redemption payout or redemption premium. This is called a declaration of acceleration of maturity. A declaration of acceleration of maturity may be canceled by the holders of a majority in principal amount of the outstanding debt securities of the affected series if (1) we have deposited with the trustee all amounts

due and owing with respect to the securities (other than principal or payments that have become due solely by reason of such acceleration) and certain other amounts, and (2) all Events of Default have been cured or waived.

Before you are allowed to bypass your trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the debt securities, the following must occur:

•you must give your trustee written notice that an Event of Default with respect to the relevant series of debt securities has occurred and remains uncured;

•the holders of at least 25% in principal amount of all outstanding debt securities of the relevant series must make a written request that the trustee take action because of the default and must offer reasonable indemnity to the trustee against the cost and other liabilities of taking that action;

•the trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity; and

•the holders of a majority in principal amount of the debt securities of that series must not have given the trustee a direction inconsistent with the above notice during that 60-day period.

However, you are entitled at any time to bring a lawsuit for the payment of money due on your debt securities on or after the due date.

Holders of a majority in principal amount of the outstanding debt securities of the affected series may waive any past defaults other than:

•in respect of the payment of principal, any premium or interest; or

•in respect of a covenant that cannot be modified or amended without the consent of each holder.

Each year, we will furnish to each trustee a written statement of certain of our officers certifying that to their knowledge we are in compliance with the indenture and the debt securities or else specifying any default.

Merger or Consolidation

•where we merge out of existence or sell all or substantially all of our assets, the resulting entity must agree to be legally responsible for our obligations under the debt securities;

•the merger or sale of assets must not cause a default on the debt securities and we must not already be in default (unless the merger or sale would cure the default). For purposes of this no-default test, a default would include an Event of Default that has occurred and has not been cured, as described under “Events of Default” above. A default for this purpose would also include any event that would be an Event of Default if the requirements for giving us a notice of default or our default having to exist for a specific period of time were disregarded;

•we must deliver certain certificates and documents to the trustee; and

•we must satisfy any other requirements specified in the prospectus supplement relating to a particular series of debt securities.

Notwithstanding any of the foregoing, any subsidiary of ours may consolidate with, merge into or transfer all or part of its property and assets to other subsidiaries of ours or to us. Additionally, this covenant shall not apply to: (1) our merger or the merger of one of our subsidiaries with an affiliate solely for the purpose of reincorporating in another jurisdiction; (2) any conversion by us or a subsidiary from an entity formed under the laws of one state to any entity formed under the laws of another state; (3) any conversion by us or a subsidiary from a limited liability company, corporation, limited partnership or

similar entity to a limited liability company, corporation, limited partnership or similar entity, whether the converting entity and converted entity are formed under the laws of the same state or a different state; or (4) any combination of (1) through (3) above.

Modification or Waiver

There are three types of changes we can make to the indenture and the debt securities issued thereunder.

Changes Requiring Your Approval

First, there are changes that we cannot make to your debt securities without your specific approval. The following is a list of those types of changes:

•change the stated maturity of the principal of, or interest on, a debt security or the terms of any sinking fund with respect to any security;

•reduce any amounts due on a debt security;

•reduce the amount of principal payable upon acceleration of the maturity of an original issue discount or indexed security following a default or upon the redemption thereof or the amount thereof provable in a bankruptcy proceeding;

•adversely affect any right of repayment at the holder’s option;

•change the place (except as otherwise described in the prospectus or prospectus supplement) or currency of payment on a debt security;

•impair your right to sue for payment;

•adversely affect any right to convert or exchange a debt security in accordance with its terms;

•modify the subordination provisions in the indenture in a manner that is adverse to holders of the outstanding debt securities;

•reduce the percentage of holders of debt securities whose consent is needed to modify or amend the indenture;

•reduce the percentage of holders of debt securities whose consent is needed to waive compliance with certain provisions of the indenture or to waive certain defaults or reduce the percentage of holders of debt securities required to satisfy quorum or voting requirements at a meeting of holders;

•modify any other aspect of the provisions of the indenture dealing with supplemental indentures with the consent of holders, waiver of past defaults, or the waiver of certain covenants; and

•change any obligation we have to pay additional amounts.

Changes Not Requiring Approval

The second type of change does not require any vote by the holders of the debt securities. This type is limited to clarifications, corrections in the indenture to match this “Description of our Debt Securities” or a similar section in any prospectus supplement, establishment of the form or terms of new securities of any series as permitted by the indenture and certain other changes that would not adversely affect holders of the outstanding debt securities in any material respect. We also do not need any approval to make any change that affects only debt securities to be issued under the indenture after the change takes effect.

Changes Requiring Majority Approval

Any other change to the indenture and the debt securities would require the following approval:

•If the change affects only one series of debt securities, it must be approved by the holders of a majority in principal amount of that series.

•If the change affects more than one series of debt securities issued under the same indenture, it must be approved by the holders of a majority in principal amount of all of the series affected by the change, with all affected series voting together as one class for this purpose.

In each case, the required approval must be given by written consent.

The holders of a majority in principal amount of a series of debt securities issued under the indenture, voting together as one class for this purpose, may waive our compliance with some of our covenants applicable to that series of debt securities. However, we cannot obtain a waiver of a payment default or of any of the matters covered by the bullet points included above under “— Changes Requiring Your Approval.”

Further Details Concerning Voting

When taking a vote, we will use the following rules to decide how much principal to attribute to a debt security:

•For original issue discount securities, we will use the principal amount that would be due and payable on the voting date if the maturity of these debt securities were accelerated to that date because of a default.

•For debt securities whose principal amount is not known (for example, because it is based on an index), we will use the principal face amount at original issuance or a special rule for that debt security described in the prospectus supplement.

•For debt securities denominated in one or more foreign currencies, we will use the U.S. dollar equivalent.

Debt securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust money for their payment or redemption or if we, any other obligor, or any affiliate of us or any obligor own such debt securities. Debt securities also will not be eligible to vote if they have been fully defeased as described later under “Defeasance — Full Defeasance.”

We generally will be entitled to set any day as a record date for the purpose of determining the holders of outstanding indenture securities that are entitled to vote or take other action under the indenture. If we set a record date for a vote or other action to be taken by holders of one or more series, that vote or action may be taken only by persons who are holders of outstanding indenture securities of those series on the record date and must be taken within eleven months following the record date.

Book-entry and other indirect holders should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the indenture or the debt securities or request a waiver.

Defeasance

The following provisions will be applicable to each series of debt securities unless we state in the applicable prospectus supplement that the provisions of covenant defeasance and full defeasance will not be applicable to that series.

Covenant Defeasance

Under current U.S. federal tax law and the indenture, we can make the deposit described below and be released from some of the restrictive covenants in the indenture under which the particular series was issued. This is called “covenant defeasance.” In that event, you would lose the protection of those restrictive covenants but would gain the protection of having money and government securities set aside in trust to repay your debt securities. If applicable, you also would be released from the subordination provisions described under “Indenture Provisions-Subordination” below. In order to achieve covenant defeasance, we must do the following:

•we must deposit in trust for the benefit of all holders of a series of debt securities a combination of cash (in such currency in which such securities are then specified as payable at stated maturity) or government obligations applicable to such securities (determined on the basis of the currency in which such securities are then specified as payable at stated maturity) that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates and any mandatory sinking fund payments or analogous payments;

•we must deliver to the trustee a legal opinion of our counsel confirming that, under current U.S. federal income tax law, we may make the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit;

•we must deliver to the trustee a legal opinion of our counsel and officers’ certificate stating that all conditions precedent to covenant defeasance have been complied with;

•defeasance must not result in a breach or violation of, or result in a default under, the indenture or any of our other material agreements or instruments;

•no default or event of default with respect to such debt securities shall have occurred and be continuing and no defaults or events of default related to bankruptcy, insolvency or reorganization shall occur during the next 90 days; and

•satisfy the conditions for covenant defeasance contained in any supplemental indentures.

If we accomplish covenant defeasance, you can still look to us for repayment of the debt securities if there were a shortfall in the trust deposit or the trustee is prevented from making payment. In fact, if one of the remaining Events of Default occurred (such as our bankruptcy) and the debt securities became immediately due and payable, there might be a shortfall. Depending on the event causing the default, you may not be able to obtain payment of the shortfall.

Full Defeasance

If there is a change in U.S. federal tax law or we obtain ruling from the U.S. Internal Revenue Service (the “IRS”), as described in the second bullet below, we can legally release ourselves from all payment and other obligations on the debt securities of a particular series (called “full defeasance”) if we put in place the following other arrangements for you to be repaid:

•we must deliver to the trustee a legal opinion confirming that there has been a change in current U.S. federal tax law or an IRS ruling that allows us to make the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit. Under current U.S. federal tax law, the deposit and our legal release from the debt securities would be treated as though we paid you your share of the cash and notes or bonds at the time the cash and notes or bonds were deposited in trust in exchange for your debt securities and you would recognize gain or loss on the debt securities at the time of the deposit;

•we must deliver to the trustee a legal opinion of our counsel and officers’ certificate stating that all conditions precedent to defeasance have been complied with;

•defeasance must not result in a breach or violation of, or constitute a default under, the indenture or any of our other material agreements or instruments;

•satisfy the conditions for full defeasance contained in any supplemental indentures.

If we ever did accomplish full defeasance, as described above, you would have to rely solely on the trust deposit for repayment of the debt securities. You could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever became bankrupt or insolvent. If applicable, you would also be released from the subordination provisions described later under “Indenture Provisions — Subordination.”

Form, Exchange and Transfer of Certificated Registered Securities

If registered debt securities cease to be issued in book-entry form, they will be issued:

•only in fully registered certificated form,

•without interest coupons, and

•unless we indicate otherwise in the prospectus supplement, in minimum denominations of $2,000 and increased amounts that are multiples of $1,000.

Holders may exchange their certificated securities for debt securities of smaller denominations or combined into fewer debt securities of larger denominations, as long as the total principal amount is not changed and as long as the denomination is greater than the minimum denomination for such securities.

Holders may exchange or transfer their certificated securities at the office of the trustee. We have appointed the trustee to act as our agent for registering debt securities in the names of holders transferring debt securities. We may appoint another entity to perform these functions or perform them ourselves.

If we have designated additional transfer agents for your debt security, they will be named in the prospectus supplement. We may appoint additional transfer agents or cancel the appointment of any particular transfer agent. We also may approve a change in the office through which any transfer agent acts.

If any certificated securities of a particular series are redeemable and we redeem less than all the debt securities of that series, we may block the transfer or exchange of those debt securities during the period beginning 15 days before the day we mail the notice of redemption and ending on the day of that mailing, in order to freeze the list of holders to prepare the mailing. We also

may refuse to register transfers or exchanges of any certificated securities selected for redemption, except that we will continue to permit transfers and exchanges of the unredeemed portion of any debt security that will be partially redeemed.

If a registered debt security is issued in book-entry form, only the depositary will be entitled to transfer and exchange the debt security as described in this subsection, since it will be the sole holder of the debt security.

Resignation of Trustee

Each trustee may resign or be removed with respect to one or more series of indenture securities provided that a successor trustee is appointed to act with respect to these series and has accepted such appointment. In the event that two or more persons are acting as trustee with respect to different series of indenture securities under the indenture, each of the trustees will be a trustee of a trust separate and apart from the trust administered by any other trustee.

Indenture Provisions-Subordination and Senior Indebtedness

Upon any distribution of our assets upon our dissolution, winding up, liquidation or reorganization, the payment of the principal of (and premium, if any) and interest, if any, on any indenture securities denominated as subordinated debt securities is to be subordinated to the extent provided in the indenture in right of payment to the prior payment in full of all Senior Indebtedness (as defined below), but our obligation to you to make payment of the principal of (and premium, if any) and interest, if any, on such subordinated debt securities will not otherwise be affected. In addition, no payment on account of principal (or premium, if any), sinking fund or interest, if any, may be made on such subordinated debt securities at any time unless full payment of all amounts due in respect of the principal (and premium, if any), sinking fund and interest on Senior Indebtedness has been made or duly provided for in money or money’s worth.

In the event that, notwithstanding the foregoing, any payment by us is received by the trustee in respect of subordinated debt securities or by the holders of any of such subordinated debt securities, upon our dissolution, winding up, liquidation or reorganization before all Senior Indebtedness is paid in full, the payment or distribution must be paid over to the holders of the Senior Indebtedness or on their behalf for application to the payment of all the Senior Indebtedness remaining unpaid until all the Senior Indebtedness has been paid in full, after giving effect to any concurrent payment or distribution to the holders of the Senior Indebtedness. Subject to the payment in full of all Senior Indebtedness upon this distribution by us, the holders of such subordinated debt securities will be subrogated to the rights of the holders of the Senior Indebtedness to the extent of payments made to the holders of the Senior Indebtedness out of the distributive share of such subordinated debt securities.

By reason of this subordination, in the event of a distribution of our assets upon our insolvency, certain of our senior creditors may recover more, ratably, than holders of any subordinated debt securities or the holders of any indenture securities that are not Senior Indebtedness. The indenture provides that these subordination provisions will not apply to money and securities held in trust under the defeasance provisions of the indenture.

Senior Indebtedness is defined in the indenture as the principal of (and premium, if any) and unpaid interest on:

•our indebtedness (including indebtedness of others guaranteed by us), whenever created, incurred, assumed or guaranteed, for money borrowed (other than indenture securities issued under the indenture and denominated as subordinated debt securities), unless in the instrument creating or evidencing the same or under which the same is outstanding it is provided that this indebtedness is not senior or prior in right of payment to the subordinated debt securities, and

•renewals, extensions, modifications and refinancings of any of this indebtedness.

If this prospectus is being delivered in connection with the offering of a series of indenture securities denominated as subordinated debt securities, the accompanying prospectus supplement will set forth the approximate amount of our Senior Indebtedness and of our other indebtedness outstanding as of a recent date.

Secured Indebtedness

Certain of our indebtedness, including certain series of indenture securities, may be secured. The prospectus supplement for each series of indenture securities will describe the terms of any security interest for such series and will indicate the approximate amount of our secured indebtedness as of a recent date. In the event of a distribution of our assets upon our insolvency, the holders of unsecured indenture securities may recover less, ratably, than holders of any of our secured indebtedness.

The Trustee under the Indenture

U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association) serves as the trustee under the indenture.

Certain Considerations Relating to Foreign Currencies

Debt securities denominated or payable in foreign currencies may entail significant risks. These risks include the possibility of significant fluctuations in the foreign currency markets, the imposition or modification of foreign exchange controls and potential illiquidity in the secondary market. These risks will vary depending upon the currency or currencies involved and will be more fully described in the applicable prospectus supplement.

Book-Entry Procedures

Unless otherwise specified in the applicable prospectus supplement, the Depository Trust Company, or DTC, will act as securities depositary for the debt securities. The debt securities will be issued as fully registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. One fully-registered certificate will be issued for the debt securities, in the aggregate principal amount of such issue, and will be deposited with DTC.

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity, corporate and municipal debt issues, and money market instruments from over 100 countries that DTC’s participants, or Direct Participants, deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation, or DTCC.

DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly, or Indirect Participants. DTC has Standard & Poor’s Ratings Services’ highest rating: AAA. The DTC Rules applicable to its participants are on file with the SEC. More information about DTC can be found at www.dtcc.com and www.dtc.org.

Purchases of debt securities under the DTC system must be made by or through Direct Participants, which will receive a credit for the debt securities on DTC’s records. The ownership interest of each actual purchaser of each security, or the “Beneficial Owner,” is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the debt securities are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in debt securities, except in the event that use of the book-entry system for the debt securities is discontinued.

To facilitate subsequent transfers, all debt securities deposited by Direct Participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co. or such other name as may be requested by an authorized representative of DTC. The deposit of debt securities with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the debt securities; DTC’s records reflect only the identity of the Direct Participants to whose accounts such debt securities are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Redemption notices shall be sent to DTC. If less than all of the debt securities within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.

Redemption proceeds, distributions, and interest payments on the debt securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct Participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us or the trustee on the payment date in accordance with their respective holdings shown on DTC’s records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such Participant and not of DTC nor its nominee, the trustee, or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds, distributions, and interest payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of us or the trustee, but disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect Participants.

DTC may discontinue providing its services as securities depository with respect to the debt securities at any time by giving reasonable notice to us or to the trustee. Under such circumstances, in the event that a successor securities depository is not obtained, certificates are required to be printed and delivered. We may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository). In that event, certificates will be printed and delivered to DTC.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.
