Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Accounting and Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. As an investment company, the Fund follows accounting and reporting guidance as set forth in Topic 946 (“Financial Services - Investment Companies”) of the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification, as amended (“ASC”). Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and money market mutual funds with maturities of, or the ability to redeem or liquidate holdings, within 90 days or less. Cash and cash equivalents are held in two bank accounts with two financial institutions, Mitsubishi UFJ Financial Group, Inc. ("MUFG Bank") and U.S. Bank National Association ("US Bank"), and as a result are subject to custodial concentration risk for cash and cash equivalents. Any cash held at US Bank in excess of the Federal Deposit Insurance Corporation (“FDIC”) limit of $250,000 is uninsured by the FDIC, while all cash held at MUFG Bank is uninsured by the FDIC. Money market mutual funds held as cash equivalents are valued at their most recently traded net asset value. Within cash and cash equivalents, as of June 30, 2024, the Fund held 26,621,359 units in the First American Government Obligations Fund Class Z (Ticker Symbol: FGZXX) valued at $1 per unit at a yield of 5.20% and $200,000 in cash, which together represented 9.35% of the net assets of the Fund. Within cash and cash equivalents, as of December 31, 2023, the Fund held 17,030,603 units in the First American Government Obligations Fund Class Z (Ticker Symbol: FGZXX) valued at $1 per unit at a yield of 5.26%, and $200,000 in cash, which together represented 7.58% of the net assets of the Fund. Interest on Loans Interest income on loans is recognized on an accrual basis using the effective interest method including amounts resulting from the accretion of discount on loans from warrants included as additional compensation as part of the loan agreements. Additionally, fees received as part of the transaction are added to the loan discount and accreted over the life of the loan. Realized Gains and Losses from Loans Realized gains or losses on the sale of loans are computed using the difference between the amortized cost and the sales proceeds. Realized losses on loan write-offs are recognized when management determines that a loan is uncollectible. Investment Valuation The Fund accounts for loans for which market quotations are not readily available at fair value as determined in good faith by the Manager, who has been appointed as the Fund's valuation designee, pursuant to Rule 2a-5 under the 1940 Act. Subject to the oversight of the Fund's Board, all valuations are determined under the direction of the Manager, in accordance with the valuation methods described below and Rule 2a-5. As of June 30, 2024 and December 31, 2023, the financial statements included nonmarketable investments of $380.9 million and $403.6 million, respectively, (or 91.5% and 93.8% of total assets, respectively) with the fair values determined by the Manager in the absence of readily determinable market values. Because of the inherent uncertainty of these valuations, estimated fair values of such investments may differ significantly from the fair values that would have been used had a readily available market for the securities existed, and the differences could be material. Below is the information used by the Manager in making these estimates. Loans The Fund defines fair value as the price that would be received to sell an asset or paid to lower a liability in an orderly transaction between market participants at the measurement date. Because there is no readily available market price and no secondary market for substantially all of the debt investments made by the Fund in its borrowing portfolio companies, Management determines fair value based on hypothetical markets, and on several factors related to each borrower, including, but not limited to, the borrower’s payment history, available cash and “burn rate,” revenues, net income or loss, the likelihood that the borrower will be able to secure additional financing in the future, and an evaluation of the general interest rate environment. The amount of any valuation adjustment considers the estimated amount and timing of cash payments of principal and interest from the borrower and/or liquidation analysis and is determined based upon a credit analysis of the borrower and an analysis of the expected recovery from the borrower, including consideration of factors such as the nature and quality of the Fund’s security interests in collateral, the estimated fair value of the Fund’s collateral, the size of the loan, and the estimated time that will elapse before the Fund achieves a recovery. Management has evaluated these factors and has concluded that the effect of deterioration in the quality of the underlying collateral, increase in size of the loan, increase in the estimated time to recovery and increase in the hypothetical market coupon rate would have the effect of lowering the fair value of the current portfolio of loans. Non-Accrual Loans The Fund’s policy is to classify a loan as non-accrual when the portfolio company is delinquent for three consecutive months on its monthly loan payment, or, in the opinion of Management, either ceases or drastically curtails its operations and Management deems that it is unlikely that the loan will return to performing status. When a loan is placed on non-accrual status, all interest previously accrued but not collected is reversed for the quarter in which the loan was placed on non-accrual status. Any uncollected interest related to quarters prior to when the loan was placed on non-accrual status is added to the principal balance, and the aggregate balance of the principal and interest is evaluated in accordance with the policy for valuation of loans in determining Management’s best estimate of fair value. Interest received by the Fund on non-accrual loans will be recognized as interest income if and when the proceeds exceed the book value of the respective loan. If a borrower of a non-accrual loan resumes making regular payments and Management believes that such borrower has regained the ability to service the loan on a sustainable basis, the loan is reclassified back to accrual or performing status. Interest that would have been accrued during the time a loan was classified as non-accrual will be added back to the remaining payment schedule, causing a change in the effective interest rate. As of June 30, 2024 and December 31, 2023, loans with a cost basis of $44.7 million and $19.4 million and a fair value of $14.8 million and $5.8 million, respectively, were classified as non-accrual. Warrants and Equity Securities Warrants and equity securities received in connection with loan transactions are measured at fair value at the time of acquisition. Warrants are valued based on a Black-Scholes option pricing model which considers, among several factors, the underlying stock value, expected term, volatility, and risk-free interest rate. It is anticipated that such securities will be distributed by the Fund to the Company simultaneously with, or shortly following, their acquisition. The underlying asset value is estimated based on available information. Volatility, or the amount of uncertainty or risk about the size of the changes in the warrant price, is based on an index of publicly traded companies grouped by industry and which are similar in nature to the underlying portfolio companies issuing the warrant (“Industry Index”). The volatility assumption for each Industry Index is based on the average volatility for individual public companies within the portfolio company’s industry for a period of time approximating the expected life of the warrants. A hypothetical increase in the volatility of the warrants used in the Black-Scholes option pricing model would have the effect of increasing the fair value of the warrants. The remaining expected lives of warrants are based on historical experience of the average life of the warrants, as warrants are often exercised in the event of acquisitions, mergers, or initial public offerings and terminated due to events such as bankruptcies, restructuring activities, or additional financings. These events cause the expected term to be less than the remaining contractual term of the warrants. As of June 30, 2024 and December 31, 2023, the Fund assumed the average duration of a warrant is four years. The effect of a hypothetical increase in the estimated initial term of the warrants used in the Black-Scholes option pricing model would have the effect of increasing the fair value of the warrants. However, the estimated initial term of the warrants is one factor, of many, used in the valuation of warrants, and by itself does not have a significant impact on the results of operations. The risk-free interest rate is derived from the constant maturity tables issued by the U.S. Treasury Department. The effect of a hypothetical increase in the estimated risk-free rate used in the Black-Scholes option pricing model would have the effect of increasing the fair value of the warrants. Other Assets and Liabilities Other assets include costs incurred in conjunction with borrowings under the Fund's debt facility and are stated at initial cost. These costs are amortized over the estimated life of the facility, which currently matures on October 18, 2026. The amortization of these costs is recorded as interest expense in the Condensed Statements of Operations. The fair values of other assets and accrued liabilities are estimated at their carrying values because of the short-term nature of these assets and liabilities. The carrying value of the borrowings under the debt facility approximates their fair value based on the borrowing rates available to the Fund. Commitment Fees Unearned income and commitment fees on loans are recognized using the effective-interest method over the term of the loan. Commitment fees are carried as liabilities when received for commitments upon which no draws have been made. When the first draw is made, the fee is treated as unearned income and is recognized as described above. If a draw is never made, the forfeited commitment fee less any applicable legal costs becomes recognized as other income after the commitment expires. Derivative Instruments The Fund uses derivative instruments to manage its exposure to changes in interest rates on expected borrowings under its debt facility, as the Fund originates fixed rate loans (see Note 8). Derivative instruments are primarily valued on the basis of quotes obtained from banks, brokers and dealers and adjusted for counterparty risk and the optionality of the interest rate terms. The valuation of the derivative instruments also considers the future expected interest rates on the notional principal balance remaining which is comparable to what a prospective acquirer would pay on the measurement date. Valuation pricing models consider inputs such as forward rates, anticipated interest rate volatility relating to the reference rate, as well as time value and other factors underlying derivative instruments. The Fund is a party to master netting arrangements with Zions Bancorporation, N.A., however, the Fund has elected not to offset assets and liabilities under these arrangements for financial statement presentation purposes. Contracts are recorded at gross fair value in either derivative assets or derivative liability in the Condensed Statements of Assets and Liabilities, depending on whether the fair value of the contract is in favor of the Fund or the counterparty. The changes in fair value are recorded in net change in unrealized gain (loss) from derivative instruments in the Condensed Statements of Operations and the monthly interest received or paid on the contract, if any, is recorded in net realized gain (loss) from derivative instruments in the Condensed Statements of Operations. The interest rate collar instruments are contractually scheduled to terminate on December 31, 2024 and December 31, 2025.
