| (a) | Investment transactions are accounted for on the trade date;  | 
| (b) | Under procedures established by the board of directors (the “Board”), we value investments, including certain senior secured debt, subordinated debt and other debt securities with maturities greater than  mid-marketpricing as a practical expedient for fair value unless a different point within the range is more representative. If and when market quotations are deemed not to represent fair value, we may utilize independent third-party valuation firms to assist us in determining the fair value of material assets. Accordingly, such investments go through our multi-step valuation process as described below. In each such case, independent valuation firms, that may from time to time be engaged by the Board, consider observable market inputs together with significant unobservable inputs in arriving at their valuation recommendations. Debt investments with maturities of | 
| (1) | our quarterly valuation process begins with each portfolio company or investment being initially valued by the investment professionals of the Investment Adviser responsible for the portfolio investment;  | 
| (2) | preliminary valuation conclusions are then documented and discussed with senior management of the Investment Adviser;  | 
| (3) | independent valuation firms engaged by the Board conduct independent appraisals and review the Investment Adviser’s preliminary valuations and make their own independent assessment for all material assets;  | 
| (4) | the audit committee of the Board reviews the preliminary valuation of the Investment Adviser and that of the independent valuation firm and responds to the valuation recommendation of the independent valuation firm, if any, to reflect any comments; and  | 
| (5) | the Board discusses valuations and determines the fair value of each investment in our portfolio in good faith based on the input of the Investment Adviser, the respective independent valuation firm, if any, and the audit committee.  | 
| (c) | Gains or losses on investments are calculated by using the specific identification method.  | 
| (d) | The Company records dividend income and interest, adjusted for amortization of premium and accretion of discount, on an accrual basis. Loan origination fees, original issue discount, and market discounts are capitalized and we amortize such amounts into income using the effective interest method. Upon the prepayment of a loan, any unamortized loan origination fees are recorded as interest income. We record call premiums received on loans repaid as interest income when we receive such amounts. Capital structuring fees, amendment fees, consent fees, and any other  non-recurringfee income as well as a management fee and other fee income for services rendered, if any, are recorded as other income when earned. | 
| (e) | The Company intends to comply with the applicable provisions of the Code pertaining to regulated investment companies to make distributions of taxable income sufficient to relieve it of substantially all U.S. federal income taxes. The Company, at its discretion, may carry forward taxable income in excess of calendar year distributions and pay a  | 
| (f) | Book and tax basis differences relating to stockholder distributions and other permanent book and tax differences are typically reclassified among the Company’s capital accounts annually. In addition, the character of income and gains to be distributed is determined in accordance with income tax regulations that may differ from GAAP.  | 
| (g) | Distributions to common stockholders are recorded as of the record date. The amount to be paid out as a distribution is determined by the Board. Net realized capital gains, if any, are generally distributed or deemed distributed at least annually.  | 
| (h) | In accordance with Regulation  S-Xand ASC Topic 810— Consolidation | 
| (i) | The accounting records of the Company are maintained in U.S. dollars. Any assets and liabilities denominated in foreign currencies are translated into U.S. dollars based on the rate of exchange of such currencies against U.S. dollars on the date of valuation. The Company will not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations would be included with the net unrealized gain or loss from investments. The Company’s investments in foreign securities, if any, may involve certain risks, including without limitation: foreign exchange restrictions, expropriation, taxation or other political, social or economic risks, all of which could affect the market and/or credit risk of the investment. In addition, changes in the relationship of foreign currencies to the U.S. dollar can significantly affect the value of these investments in terms of U.S. dollars and therefore the earnings of the Company.  | 
| (j) | In accordance with ASC  835-30,the Company reports origination and other expenses related to certain debt issuances as a direct deduction from the carrying amount of the debt liability. Applicable expenses are deferred and amortized using either the effective interest method or the straight-line method over the stated life. The straight-line method may be used on revolving facilities and/or when it approximates the effective yield method. | 
| (k) | The Company may enter into forward exchange contracts in order to hedge against foreign currency risk. These contracts are  marked-to-market | 
| (l) | The Company records expenses related to shelf registration statements and applicable equity offering costs as prepaid assets. These expenses are typically charged as a reduction of capital upon the sale of shares or expensed, in accordance with ASC  946-20-25. | 
| (m) | Investments that are expected to pay regularly scheduled interest in cash are generally placed on  non-accrualstatus when principal or interest cash payments are past due non-accrualinvestments are restored to accrual status if past due principal and interest are paid in cash, and in management’s judgment, are likely to continue timely payment of their remaining principal and interest obligations. Cash interest payments received on such investments may be recognized as income or applied to principal depending on management’s judgment. | 
| (n) | The Company defines cash equivalents as securities that are readily convertible into known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only securities with a maturity of three months or less would qualify, with limited exceptions. The Company believes that certain U.S. Treasury bills, repurchase agreements and other high-quality, short-term debt securities would qualify as cash equivalents.  |

| (1) | Total amount of each class of senior securities outstanding (in thousands) at the end of the period presented.  | 
| (2) | The asset coverage ratio for a class of senior securities representing indebtedness is calculated as our consolidated total assets, less all liabilities and indebtedness not represented by senior securities, divided by all senior securities representing indebtedness. This asset coverage ratio is multiplied by one thousand to determine the Asset Coverage Per Unit. In order to determine the specific Asset Coverage Per Unit for each class of debt, the total Asset Coverage Per Unit is allocated based on the amount outstanding in each class of debt at the end of the period. As of March 31, 2024, asset coverage was 185.4%.  | 
| (3) | The amount to which such class of senior security would be entitled upon the involuntary liquidation of the issuer in preference to any security junior to it.  | 
| (4) | Not applicable except for the 2042 Unsecured Notes which were publicly traded. The Average Market Value Per Unit is calculated by taking the daily average closing price during the period and dividing it by twenty-five dollars per share and multiplying the result by one thousand to determine a unit price per thousand consistent with Asset Coverage Per Unit. The average market value for the fiscal 2016, 2015 and 2014 periods was $100,175, $98,196 and $94,301, respectively.  |
