Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Organization Organization
Blackstone Secured Lending Fund (together with its consolidated subsidiaries, the “Company”), is a Delaware statutory trust formed on March 26, 2018, and structured as an externally managed, non-diversified closed-end management investment company. On October 26, 2018, the Company elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (together with the rules and regulations promulgated thereunder, the “1940 Act”). In addition, the Company elected to be treated for U.S. federal income tax purposes, and intends to qualify annually, as a regulated investment company (a “RIC”), under Subchapter M of the Internal Revenue Code of 1986, as amended (together with the rules and regulations promulgated thereunder, the “Code”).

The Company is externally managed by Blackstone Credit BDC Advisors LLC (the “Adviser”) an affiliate of Blackstone Alternative Credit Advisors LP (the “Administrator” and, collectively with its affiliates in the credit-focused business of Blackstone Inc. (“Blackstone”), “Blackstone Credit,” which, for the avoidance of doubt, excludes Harvest Fund Advisors LLC and Blackstone Insurance Solutions). The Administrator provides certain administrative and other services necessary for the Company to operate pursuant to an administration agreement (the “Administration Agreement”).  Blackstone Credit is part of the credit-focused platform of Blackstone and is the primary part of its Credit & Insurance reporting segment.

The Company’s investment objectives are to generate current income and, to a lesser extent, long-term capital appreciation. The Company seeks to achieve its investment objectives primarily through originated loans and other securities, including syndicated loans, of private U.S. companies, typically in the form of first lien senior secured and unitranche loans (including first-out/last-out loans), and to a lesser extent, second lien, third lien, unsecured and subordinated loans and other debt and equity securities.

The Company commenced its loan origination and investment activities on November 20, 2018.
On October 28, 2021, the Company priced its initial public offering (“IPO”) and the Company's shares began trading on the New York Stock Exchange (“NYSE”). See "Note 8. Net Assets" for further details.

Accounting Policies [Abstract]  
Significant Accounting Policies Significant Accounting Policies
Basis of Presentation
The consolidated financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States (“GAAP”).  As an investment company, the Company applies the accounting and reporting guidance in Accounting Standards Codification (“ASC”) Topic 946, Financial Services – Investment Companies (“ASC 946”) issued by the Financial Accounting Standards Board (“FASB”).
The interim consolidated financial statements have been prepared in accordance with GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 6 and Article 10 of Regulation S-X. Accordingly, certain disclosures accompanying the annual consolidated financial statements prepared in accordance with GAAP are omitted.  In the opinion of management, all adjustments considered necessary for the fair presentation of the consolidated financial statements for the interim period presented, have been included. The current period’s results of operations will not necessarily be indicative of results that ultimately may be achieved for the fiscal year ending December 31, 2023.
All intercompany balances and transactions have been eliminated.
Certain prior period information has been reclassified to conform to the current period presentation.
Use of Estimates
The preparation of consolidated financial statements in conformity with 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 consolidated financial statements. Such amounts could differ from those estimates and such differences could be material. Assumptions and estimates regarding the valuation of investments involve a higher degree of
judgment and complexity and these assumptions and estimates may be significant to the consolidated financial statements. Actual results may ultimately differ from those estimates.
Consolidation
As provided under ASC 946, the Company will not consolidate its investment in a company other than an investment company subsidiary or a controlled operating company whose business consists of providing services to the Company.

The Company consolidated the results of the Company’s wholly-owned subsidiaries which are considered to be investment companies. As of March 31, 2023 and December 31, 2022, the Company's consolidated subsidiaries were BGSL Jackson Hole Funding LLC (“Jackson Hole Funding”), BGSL Breckenridge Funding LLC (“Breckenridge Funding”), BGSL Big Sky Funding LLC (“Big Sky Funding”) and BGSL Investments LLC (“BGSL Investments”).
Cash and Cash Equivalents
Cash and cash equivalents consist of demand deposits and highly liquid investments, such as money market funds, with original maturities of three months or less. Cash and cash equivalents are carried at cost, which approximates fair value. The Company deposits its cash and cash equivalents with financial institutions and, at times, may exceed the Federal Deposit Insurance Corporation insured limit.
Investments
Investment transactions are recorded on a trade date basis.
Realized gains or losses are measured by the difference between the net proceeds received (excluding prepayment fees, if any) and the amortized cost basis of the investment using the specific identification method without regard to unrealized gains or losses previously recognized, and include investments charged off during the period, net of recoveries, and is recorded within Net Realized gain (loss) on the Consolidated Statements of Operations.
The net change in unrealized gains or losses primarily reflects the change in investment values, including the reversal of previously recorded unrealized gains or losses with respect to investments realized during the period, and is recorded within Net unrealized appreciation (depreciation) on the Consolidated Statements of Operations.
Valuation of Investments
The Company is required to report its investments, including those for which current market values are not readily available, at fair value.
GAAP for an investment company requires investments to be recorded at fair value. The Company values its investments in accordance with ASC 820, Fair Value Measurements (“ASC 820”), which defines fair value as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the applicable measurement date, and Rule 2a-5 under the 1940 Act.
Fair value is based on observable market prices or parameters or derived from such prices or parameters when such quotations are readily available. In accordance with Rule 2a-5 under the 1940 Act, a market quotation is "readily available" only when it is a quoted price (unadjusted) in active markets for identical instruments that a fund can access at the measurement date, provided that such a quotation is not considered to be readily available if it is not reliable. The Company utilizes mid-market pricing (i.e., mid-point of average bid and ask prices) to value these investments. These market quotations are obtained from independent pricing services, if available; otherwise generally from at least two principal market makers or primary market dealers.
Where prices or inputs are not available or, in the judgment of the Board, not reliable, valuation techniques based on the facts and circumstances of the particular investment will be utilized. These valuation approaches involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the investments or market and the investments’ complexity. In the absence of observable, reliable market prices, the Company values its investments using various valuation methodologies applied on a consistent basis.
An enterprise value (“EV”) analysis is generally performed to determine the value of equity investments, control debt investments and non-control debt investments that are credit-impaired, and to determine if debt investments are credit impaired.
The Adviser will generally utilize approaches including the market approach, the income approach or both approaches, as appropriate, when calculating EV. The primary method for determining EV for non-control investments, and control investments without reliable projections, uses a multiple analysis whereby appropriate multiples are applied to the portfolio company’s earnings before interest, taxes, depreciation and amortization (“EBITDA”) or another key financial metric (e.g., such as revenues, cash flows or net income) (“Performance Multiple”). Performance Multiples are typically determined based upon a review of publicly traded comparable companies and market comparable transactions, if any. The second method for determining EV (and primary method for control investments with reliable projections) uses a discounted cash flow analysis whereby future expected cash flows and the anticipated terminal value of the portfolio company are discounted to determine a present value using estimated discount rates. The income approach is generally used when the Adviser has visibility into the long term projected cash flows of a portfolio company.
If debt investments are credit-impaired, which occurs when there is insufficient coverage under the enterprise value analysis through the respective investment’s position in the capital structure, the Adviser generally uses the enterprise value “waterfall” approach or a recovery method (if a liquidation or restructuring is deemed likely) to determine fair value. For debt investments that are not determined to be credit-impaired, the Adviser generally uses a market interest rate yield analysis to determine fair value. To determine fair value using a yield analysis, the expected cash flows are projected based on the contractual terms of the debt security and discounted back to the measurement date based on a market yield. A market yield is determined based upon an assessment of current and expected market yields for similar investments and risk profiles. The Company considers the current contractual interest rate, the maturity and other terms of the investment relative to risk of the company and the specific investment. A key determinant of risk, among other things, is the leverage through the investment relative to the enterprise value of the portfolio company. As debt investments held by the Company are substantially illiquid with no active transaction market, the Company depends on primary market data, including newly funded transactions, as well as secondary market data with respect to high yield debt instruments and syndicated loans, as inputs in determining the appropriate market yield, as applicable. The fair value of loans with call protection is generally capped at par plus applicable prepayment premium in effect at the measurement date.
ASC 820 prioritizes the use of observable market prices derived from such prices. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The levels used for classifying investments are not necessarily an indication of the risk associated with investing in these securities. The three levels of the fair value hierarchy are as follows:
•Level 1: Inputs to the valuation methodology are quoted prices available in active markets for identical instruments as of the reporting date. The types of financial instruments included in Level 1 include unrestricted securities, including equities and derivatives, listed in active markets.
•Level 2:  Inputs to the valuation methodology are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date. The types of financial instruments in this category include less liquid and restricted securities listed in active markets, securities traded in other than active markets, government and agency securities and certain over-the-counter derivatives where the fair value is based on observable inputs.
•Level 3:  Inputs to the valuation methodology are unobservable and significant to overall fair value measurement. The inputs into the determination of fair value require significant management judgment or estimation. Financial instruments that are included in this category include debt and equity investments in privately held entities, collateralized loan obligations (“CLOs”) and certain over-the-counter derivatives where the fair value is based on unobservable inputs.
In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment’s level within the fair value hierarchy is based on the lowest level of input that is significant to the overall fair value measurement. The Adviser’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment. Transfers between levels, if any, are recognized at the beginning of the quarter in which the transfer occurs.
The Company evaluates the source of the inputs, including any markets in which its investments are trading (or any markets in which securities with similar attributes are trading), in determining fair value. When an investment is valued based on prices provided by reputable dealers or pricing services (that is, broker quotes), the Company subjects those prices to various criteria in making the determination as to whether a particular investment would qualify for treatment as a Level 2 or Level 3 investment.
Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of the Company’s investments may fluctuate from period to period, and these differences could be material. Additionally, the fair value of the Company’s investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that the Company may ultimately realize. Further, such investments are generally subject to legal and other restrictions on resale or otherwise are less liquid than publicly traded securities. If the Company was required to liquidate a portfolio investment in a forced or liquidation sale, it could realize significantly less than the value at which the Company has recorded it. In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the unrealized gains or losses reflected in the valuations currently assigned.  See “Item 2. Management’s Discussion and Analysis of Financial Conditions and Results of Operations—Critical Accounting Estimates.”
Receivables/Payables From Investments Sold/Purchased
Receivables/payables from investments sold/purchased consist of amounts receivable to or payable by the Company for transactions that have not settled at the reporting date.
Derivative Instruments

The Company recognizes all derivative instruments as assets or liabilities at fair value in its consolidated financial statements. Derivative contracts entered into by the Company are not designated in hedge accounting relationships and all changes in fair value are recognized through current period gains or losses.
In the normal course of business, the Company has commitments and risks resulting from its investment transactions, which may include those involving derivative instruments. Derivative instruments are measured in terms of the notional contract amount and derive their value based upon one or more underlying instruments. While the notional amount gives some indication of the Company’s derivative activity, it generally is not exchanged, but is only used as the basis on which interest and other payments are exchanged. Derivative instruments are subject to various risks similar to non-derivative instruments including market, credit, liquidity, and operational risks. The Company manages these risks on an aggregate basis as part of its risk management process.
Forward Purchase Agreement
Forward purchase agreements are recognized at fair value through current period gains or losses on the date on which the contract is entered into and are subsequently re-measured at fair value. All forward purchase agreements are carried as assets when fair value is positive and as liabilities when fair value is negative.  A forward purchase agreement is derecognized when the obligation specified in the contract is discharged, canceled or expired.
Foreign Currency Transactions

Amounts denominated in foreign currencies are translated into U.S. dollars on the following basis: (i) investments and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates effective on the last business day of the period; and (ii) purchases and sales of investments, borrowings and repayments of such borrowings, income, and expenses denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates prevailing on the transaction dates.

The Company includes net changes in fair values on investments held resulting from foreign exchange rate fluctuations in translation of assets and liabilities in foreign currencies on the Consolidated Statements of Operations, if any. Foreign security and currency translations may involve certain considerations and risks not typically associated with investing in U.S. companies and U.S. government securities. These risks include, but are not limited to, currency fluctuations and revaluations and future adverse political, social and economic developments, which could cause investments in foreign markets to be less liquid and prices more volatile than those of comparable U.S. companies or U.S. government securities.

Revenue Recognition
Interest Income
Interest income is recorded on an accrual basis and includes the accretion of discounts and amortizations of premiums.  Discounts from and premiums to par value on debt investments purchased are accreted/amortized into interest income over the life of the respective security using the effective interest method.  The amortized cost of debt investments
represents the original cost, including loan origination fees and upfront fees received that are deemed to be an adjustment to yield, adjusted for the accretion of discounts and amortization of premiums, if any. Upon prepayment of a loan or debt security, any prepayment premiums, unamortized upfront loan origination fees and unamortized discounts are recorded as interest income in the current period. For the three months ended March 31, 2023 and 2022, the Company recorded $0.4 million and $1.0 million, respectively, in non-recurring interest income (e.g., prepayment premiums, accelerated accretion of upfront loan origination fees and unamortized discounts).
PIK Income
The Company has loans in its portfolio that contain payment-in-kind (“PIK”) provisions.  PIK represents interest that is accrued and recorded as interest income at the contractual rates, increases the loan principal on the respective capitalization dates, and is generally due at maturity.  Such income is included in Payment-in-kind interest income in the Consolidated Statements of Operations.  If at any point the Company believes PIK is not expected to be realized, the investment generating PIK will be placed on non-accrual status. When a PIK investment is placed on non-accrual status, the accrued, uncapitalized interest is generally reversed through Payment-in-kind interest income. To satisfy the Company's annual RIC distribution requirements, this non-cash source of income must be included in determining the amounts to be paid out to shareholders in the form of dividends, even though the Company has not yet collected cash.
Dividend Income
Dividend income on preferred equity securities is recorded on the accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly-traded portfolio companies.
Fee Income
The Company may receive various fees in the ordinary course of business such as structuring, consent, waiver, amendment, syndication and other miscellaneous fees as well as fees for managerial assistance rendered by the Company to the portfolio companies. Such fees are recognized as income when earned or the services are rendered.
Non-Accrual Income
Loans are generally placed on non-accrual status when there is reasonable doubt whether principal or interest will be collected in full. Accrued interest is generally reversed when a loan is placed on non-accrual status. Additionally, any original issue discount and market discount are no longer accreted to interest income as of the date the loan is placed on non-accrual status.  Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding collectability. Non-accrual loans are restored to accrual status when past due principal and interest is paid current and, in management’s judgment, are likely to remain current. Management may make exceptions to this treatment and determine to not place a loan on non-accrual status if the loan has sufficient collateral value and is in the process of collection.
Organization Expenses and Offering Expenses
The Company records expenses related to public equity offerings as a reduction of capital upon completion of an offering of registered securities. The costs associated with any renewals of a shelf registration statement will be expensed as incurred.
Deferred Financing Costs and Debt Issuance Costs
Deferred financing and debt issuance costs represent fees and other direct incremental costs incurred in connection with the Company’s borrowings.  These expenses are deferred and amortized into interest expense over the life of the related debt instrument. Deferred financing costs related to revolving credit facilities are presented separately as an asset on the Company’s Consolidated Statements of Assets and Liabilities.  Debt issuance costs related to any issuance of installment debt or notes are presented net against the outstanding debt balance of the related security.
Income Taxes
The Company has elected to be treated as a BDC under the 1940 Act.  The Company also has elected to be treated as a RIC under the Code. So long as the Company maintains its status as a RIC, it generally will not pay corporate-level U.S. federal income taxes on any ordinary income or capital gains that it distributes at least annually to its shareholders as dividends. Rather, any tax liability related to income earned and distributed by the Company would represent obligations of the Company’s investors and would not be reflected in the consolidated financial statements of the Company.
The Company evaluates tax positions taken or expected to be taken in the course of preparing its consolidated financial statements to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are reserved and recorded as a tax benefit or expense in the current year. All penalties and interest associated with income taxes are included in income tax expense. Conclusions regarding tax positions are subject to review and may be adjusted at a later date based on factors including, but not limited to, on-going analyses of tax laws, regulations and interpretations thereof.
To qualify for and maintain qualification as a RIC, the Company must, among other things, meet certain source-of-income and asset diversification requirements. In addition, to qualify for RIC tax treatment, the Company must distribute to its shareholders, for each taxable year, at least 90% of the sum of (i) its “investment company taxable income” for that year (without regard to the deduction for dividends paid), which is generally its ordinary income plus the excess, if any, of its realized net short-term capital gains over its realized net long-term capital losses and (ii) its net tax-exempt income.
In addition, based on the excise tax distribution requirements, the Company is subject to a 4% nondeductible federal excise tax on undistributed income unless the Company distributes in a timely manner in each taxable year an amount at least equal to the sum of (i) 98% of its ordinary income for the calendar year, (ii) 98.2% of capital gain net income (both long-term and short-term) for the one-year period ending October 31 in that calendar year and (iii) any income realized, but not distributed, in prior years. For this purpose, however, any ordinary income or capital gain net income retained by the Company that is subject to corporate income tax is considered to have been distributed.
For the three months ended March 31, 2023 and 2022, the Company incurred $2.6 million and $1.4 million, respectively, of U.S. federal excise tax.
Distributions
To the extent that the Company has taxable income available, the Company intends to make quarterly distributions to its shareholders. Distributions to shareholders are recorded on the record date. All distributions will be paid at the discretion of the Board and will depend on the Company’s earnings, financial condition, maintenance of the Company's tax treatment as a RIC, compliance with applicable BDC regulations and such other factors as the Board may deem relevant from time to time.
Recent Accounting Pronouncements
In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848),” which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts, hedging relationships, and other transactions that reference London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848), which expanded the scope of Topic 848 to include derivative instruments impacted by discounting transition. ASU 2020-04 and ASU 2021-01 are effective for all entities through December 31, 2022. The expedients and exceptions provided by the amendments do not apply to contract modifications and hedging relationships entered into or evaluated after December 31, 2022, except for hedging transactions as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. In December 2022, the FASB issued ASU No. 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which deferred the sunset day of this guidance to December 31, 2024. The Company is currently evaluating the impact on its consolidated financial statements.

Agreements and Related Party Transactions Agreements and Related Party Transactions
Investment Advisory Agreement
On October 1, 2018, the Company entered into the original investment advisory agreement with the Adviser. The Adviser is responsible for originating prospective investments, conducting research and due diligence investigations on potential investments, analyzing investment opportunities, negotiating and structuring the Company’s investments and monitoring its investments and portfolio companies on an ongoing basis.
On October 18, 2021, the Company entered into an amended and restated investment advisory agreement (as amended and restated, the “Investment Advisory Agreement”), pursuant to which the Adviser manages the Company on a day-to-day basis. The Investment Advisory Agreement is substantially the same as the prior investment advisory agreement except, following the IPO, the incentive fee on income became subject to a twelve-quarter lookback quarterly hurdle rate of 1.50% as opposed to a single quarter measurement and became subject to an Incentive Fee Cap (as defined below) based on the Company’s Cumulative Net Return (as defined below). The amendment to the Investment Advisory Agreement does not result in higher fees (on a cumulative basis) payable to the Adviser than the fees that would have otherwise been payable to the Adviser under the original investment advisory agreement.
The Company pays the Adviser a fee for its services under the Investment Advisory Agreement consisting of two components: a management fee and an incentive fee. The cost of both the management fee and the incentive fee is borne by the shareholders. The initial term of the Investment Advisory Agreement was two years from October 1, 2018, and on May 6, 2020 and May 6, 2021, it was renewed and approved by the Board, including a majority of trustees who are not parties to the Investment Advisory Agreement or “interested persons” (as such term is defined in Section 2(a)(19) of the 1940 Act) (the “Independent Trustees”), for a one-year period. On October 18, 2021, the Board approved the amended and restated Investment Advisory Agreement for an initial term ending May 31, 2022. Unless earlier terminated, the Investment Advisory Agreement will renew automatically for successive annual periods, provided that such continuance is specifically approved at least annually by the vote of the Board and by the vote of a majority of the Independent Trustees. The Investment Advisory Agreement was most recently renewed and approved by the Board, including a majority of the Independent Trustees, on May 2, 2023 for a one-year period ending on May 31, 2024.
The Adviser has implemented a waiver effective from the consummation of the IPO to extend the Company’s pre-IPO fee structure for a period of two years. With the waiver in place, instead of having the base management fee and each incentive fee increase to 1.00% and 17.5%, respectively, following the IPO, each such fee will remain at 0.75% and 15.0% for a period of two years following the IPO (the “Waiver Period”). As a result of the fee waiver, the pre-listing management fee and incentive fee rates paid by the Company to the Adviser will not increase during the Waiver Period. Amounts waived by the Adviser are not subject to recoupment by the Adviser.
Base Management Fees
Starting from the completion of the IPO, the management fee pursuant to the Investment Advisory Agreement is payable quarterly in arrears at an annual rate of 1.0% of the average value of the Company’s gross assets at the end of the two most recently completed calendar quarters. For purposes of the Investment Advisory Agreement, gross assets means the Company’s total assets determined on a consolidated basis in accordance with GAAP, excluding undrawn commitments but including assets purchased with borrowed amounts.
Prior to the consummation of the IPO, the management fee was 0.75% of the average value of the Company’s gross assets at the end of the two most recently completed calendar quarters. In order to maintain the same management fee arrangement that the Company had in place prior to the IPO for a period of time following the completion of the IPO, the Adviser voluntarily waived its right to receive the base management fee in excess of 0.75% of the average value of the
Company’s gross assets at the end of the two most recently completed calendar quarters during the Waiver Period. Amounts waived by the Adviser are not subject to recoupment by the Adviser.
For the three months ended March 31, 2023 and 2022, base management fees were $24.7 million and $25.6 million, respectively, of which $6.2 million and $6.4 million, respectively, were waived. As of March 31, 2023 and December 31, 2022, $18.5 million and $18.6 million, respectively, was payable to the Adviser relating to management fees.
Incentive Fees
The incentive fees consist of two components that are determined independently of each other, with the result that one component may be payable even if the other is not. One component is based on income and the other component is based on capital gains, each as described below:
(i) Income based incentive fees:
The first part of the incentive fee, an income based incentive fee, is calculated and payable quarterly in arrears based on the Company’s Pre-Incentive Fee Net Investment Income Returns as defined in the Investment Advisory Agreement.  Pre-Incentive Fee Net Investment Income Returns means, as the context requires, either the dollar value of, or percentage rate of return on the value of the Company’s net assets at the end of the immediately preceding quarter from, interest income, dividend income and any other income (including any other fees (other than fees for providing managerial assistance), such as commitment, origination, structuring, diligence and consulting fees or other fees that the Company receives from portfolio companies) accrued during the calendar quarter, minus the Company’s operating expenses accrued for the quarter (including the management fee, expenses payable under the Administration Agreement, and any interest expense or fees on any credit facilities or outstanding debt and dividends paid on any issued and outstanding preferred shares, but excluding the incentive fee.  Pre-Incentive Fee Net Investment Income Returns includes, in the case of investments with a deferred interest feature (such as original issue discount, debt instruments with PIK interest and zero coupon securities)), accrued income that the Company has not yet received in cash.  Pre-incentive fee net investment income excludes any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. The Company excludes the impact of expense support payments and recoupments from pre-incentive fee net investment income. Shareholders may be charged a fee on an income amount that is higher than the income they may ultimately receive.
Pre-Incentive Fee Net Investment Income Returns, expressed as a rate of return on the value of our net assets at the end of the immediately preceding quarter, is compared to a “hurdle rate” of return of 1.5% per quarter (6.0% annualized).
Pursuant to the Investment Advisory Agreement, the Company is required to pay an income based incentive fee of 15% prior to the consummation of the IPO and 17.5% following the consummation of the IPO, with a 1.5% hurdle and 100% catch-up. However, the Adviser has implemented a voluntary waiver with respect to the income based incentive fee. The Adviser has voluntarily waived its right to receive an income based incentive fee above 15% during the Waiver Period and amounts waived by the Adviser are not subject to recoupment by the Adviser.

The Company pays the Adviser an income based incentive fee based on its aggregate pre-incentive fee net investment income, as adjusted as described above, from the calendar quarter then ending and the eleven preceding calendar quarters (such period, the “Trailing Twelve Quarters”).

The hurdle amount for the income based incentive fee will be determined on a quarterly basis and is equal to 1.5% multiplied by the Company’s NAV at the beginning of each applicable calendar quarter comprising the relevant Trailing Twelve Quarters. The hurdle amount is calculated after making appropriate adjustments for issuances by the Company of common shares, including issuances pursuant to its dividend reinvestment plan and distributions that occurred during the relevant Trailing Twelve Quarters. The income based incentive fee for any partial period will be appropriately prorated.

For the income based incentive fee, the Company will pay the Adviser a quarterly incentive fee based on the amount by which (A) aggregate pre-incentive fee net investment income in respect of the relevant Trailing Twelve Quarters exceeds (B) the hurdle amount for such Trailing Twelve Quarters. The amount of the excess of (A) over (B) described in this paragraph for such Trailing Twelve Quarters is referred to as the “Excess Income Amount”.

The income based incentive fee for each quarter will be determined as follows:

•No income based incentive fee is payable to the Adviser for any calendar quarter for which there is no Excess Income Amount.
•The Adviser will be paid 100% of the pre-incentive fee net investment income in respect of the Trailing Twelve Quarters, if any, that exceeds the hurdle amount for such Trailing Twelve Quarters, but is less than or equal to an amount, which we refer to as the “Catch-up Amount,” determined as the sum of 1.76% (7.06% annualized) prior to the end of the Waiver Period, or 1.82% (7.27% annualized) following the Waiver Period, multiplied by the Company’s NAV at the beginning of each applicable calendar quarter comprising the relevant Trailing Twelve Quarters that is included in the calculation of the incentive fee based on income.

•The Adviser will be paid 15% prior to the end of the Waiver Period, or 17.5% following the Waiver Period, of the pre-incentive fee net investment income in respect of the Trailing Twelve Quarters that exceeds the Catch-up Amount.

The amount of the income based incentive fee that will be paid to the Adviser for a particular quarter will equal the excess of (a) the income based incentive fee so calculated over (b) the aggregate income based incentive fee that was paid in respect of the first eleven calendar quarters included in the relevant Trailing Twelve Quarters subject to the Incentive Fee Cap as described below.

The income based incentive fee that will be paid to the Adviser for a particular quarter is subject to a cap (the “Incentive Fee Cap”). The Incentive Fee Cap for any quarter is an amount equal to (a) 15% prior to the end of the Waiver Period, or 17.5% following the Waiver Period, of the Cumulative Net Return (as defined below) during the relevant Trailing Twelve Quarters minus (b) the aggregate income based incentive fee that was paid in respect of the first eleven calendar quarters (or the portion thereof) included in the relevant Trailing Twelve Quarters.

“Cumulative Net Return” means (x) the pre-incentive fee net investment income in respect of the relevant Trailing Twelve Quarters minus (y) any Net Capital Loss (as defined below), if any, in respect of the relevant Trailing Twelve Quarters. If, in any quarter, the Incentive Fee Cap is zero or a negative value, the Company will pay no income based incentive fee to the Adviser for such quarter. If, in any quarter, the Incentive Fee Cap for such quarter is a positive value but is less than the income based incentive fee that is payable to the Adviser for such quarter (before giving effect to the Incentive Fee Cap) calculated as described above, the Company will pay an income based incentive fee to the Adviser equal to the Incentive Fee Cap for such quarter. If, in any quarter, the Incentive Fee Cap for such quarter is equal to or greater than the income based incentive fee that is payable to the Adviser for such quarter (before giving effect to the Incentive Fee Cap) calculated as described above, the Company will pay an income based incentive fee to the Adviser equal to the incentive fee calculated as described above for such quarter without regard to the Incentive Fee Cap.

“Net Capital Loss” in respect of a particular period means the difference, if positive, between (i) aggregate capital losses, whether realized or unrealized, in such period and (ii) aggregate capital gains, whether realized or unrealized, in such period.

These calculations are prorated for any period of less than three months and adjusted for any share issuances or repurchases during the relevant quarter. As the consummation of the IPO occurred on a date other than the first day of a calendar quarter, the income based incentive fee with respect to the Company’s pre-incentive fee net investment income was calculated for such calendar quarter at a weighted rate calculated based on the fee rates applicable before and after the consummation of the IPO based on the number of days in such calendar quarter before and after the consummation of the IPO. In no event will the amendments to the income based incentive fee include the incentive fee cap and allow the Adviser to receive greater cumulative income based incentive fees under the Investment Advisory Agreement than it would have under the prior investment advisory agreement. Amounts waived by the Adviser are not subject to recoupment by the Adviser.
(ii) Capital gains based incentive fee:
Starting from the completion of the IPO, the second part of the incentive fee, a capital gains incentive fee, is determined and payable in arrears as of the end of each calendar year in an amount equal to 17.5% of realized capital gains, if any, on a cumulative basis from inception through the end of each calendar year, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any previously paid capital gain incentive fees as calculated in accordance with GAAP.
Prior to the IPO, the second part of the incentive fee, a capital gains incentive fee, was determined and payable in arrears as of the end of each calendar year in an amount equal to 15.0% of realized capital gains, if any, on a cumulative basis from inception through the end of each calendar year, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any previously paid capital gain incentive fees as calculated in accordance with GAAP. However, similar to the voluntary waivers referenced above, the Adviser voluntarily waived its right to
receive a capital gains based incentive fee above 15% from the date of consummation of the IPO through the Waiver Period. The Company will accrue, but will not pay, a capital gains incentive fee with respect to unrealized appreciation because a capital gains incentive fee would be owed to the Adviser if the Company were to sell the relevant investment and realize a capital gain. Amounts waived by the Adviser are not subject to recoupment by the Adviser.
For the three months ended March 31, 2023 and 2022 the Company accrued income based incentive fees of $30.4 million and $21.3 million, respectively, of which $4.3 million and $3.0 million, respectively, were waived. As of March 31, 2023 and December 31, 2022, $26.1 million and $24.8 million, respectively, was payable to the Adviser for income based incentive fees.
For the three months ended March 31, 2023 and 2022 , the Company accrued capital gains incentive fees of $(1.6) million and $0.7 million, respectively.
Administration Agreement
On October 1, 2018, the Company entered into an Administration Agreement with the Administrator. Under the terms of the Administration Agreement, the Administrator provides, or oversees the performance of, administrative and compliance services, including, but not limited to, maintaining financial records, overseeing the calculation of NAV, compliance monitoring (including diligence and oversight of the Company’s other service providers), preparing reports to shareholders and reports filed with the United States Securities and Exchange Commission (“SEC”), preparing materials and coordinating meetings of the Company’s Board, managing the payment of expenses and the performance of administrative and professional services rendered by others and providing office space, equipment and office services. The Administrator may also offer to provide, on the Company’s behalf, managerial assistance to the Company’s portfolio companies. The initial term of the agreement was two years from October 1, 2018. Unless earlier terminated, the Administration Agreement will renew automatically for successive annual periods, provided that such continuance is approved at least annually by (i) the vote of the Board or by a majority vote of the outstanding voting securities of the Company and (ii) the vote of a majority of the Independent Trustees. The Administration Agreement was most recently renewed and approved by the Board, including a majority of the Independent Trustees, on May 2, 2023, for a one-year period.
For providing these services, the Company will reimburse the Administrator for its costs, expenses and allocable portion of overhead (including rent, office equipment and utilities) and other expenses incurred by the Administrator in performing its administrative obligations under the Administration Agreement, including but not limited to: (i) the Company’s chief compliance officer, chief financial officer and their respective staffs; (ii) investor relations, legal, information technology, operations and other non-investment professionals at the Administrator that perform duties for the Company; and (iii) any internal audit group personnel of Blackstone or any of its affiliates. The Administrator has elected to forgo any reimbursement for rent and other occupancy costs for the three months ended March 31, 2023 and 2022.
For the three months ended March 31, 2023 and 2022, the Company incurred $0.4 million and $0.8 million, respectively, in expenses under the Administration Agreement, which were recorded in administrative service expenses in the Company’s Consolidated Statements of Operations. As of March 31, 2023 and December 31, 2022, $0.3 million and $1.2 million, respectively, was unpaid and included in Due to affiliates in the Consolidated Statements of Assets and Liabilities.  
Sub-Administration and Custody Agreement
On October 1, 2018, the Administrator entered into a sub-administration agreement (the “Sub-Administration Agreement”) with State Street Bank and Trust Company (the “Sub-Administrator”) under which the Sub-Administrator provides various accounting and administrative services to the Company.  The Sub-Administrator also serves as the Company’s custodian (the “Custodian”).  The initial term of the Sub-Administration Agreement is two years from the effective date and after expiration of the initial term and the Sub-Administration Agreement shall automatically renew for successive one-year periods, unless a written notice of non-renewal is delivered prior to 120 days prior to the expiration of the initial term or renewal term.  
Expense Support and Conditional Reimbursement Agreement
On December 12, 2018, the Company entered into an Expense Support and Conditional Reimbursement Agreement (the “Expense Support Agreement”) with the Adviser pursuant to which the Adviser was able to elect to pay certain expenses of the Company on the Company’s behalf (each, an “Expense Payment”), provided that no portion of the payment was used to pay any interest of the Company. Any Expense Payment that the Adviser committed to pay was to be paid by the Adviser to the Company in any combination of cash or other immediately available funds no later than forty-five days after such commitment was made in writing, and/or offset against amounts due from the Company to the Adviser or its affiliates.
Pursuant to the Expense Support Agreement, following any calendar quarter in which Available Operating Funds (as defined below) exceeded the cumulative distributions accrued to the Company’s shareholders based on distributions declared with respect to record dates occurring in such calendar quarter (the “Excess Operating Funds”), the Company was required to pay such Excess Operating Funds, or a portion thereof, to the Adviser until such time as all Expense Payments made by the Adviser to the Company within three years prior to the last business day of such calendar quarter were reimbursed. Any payments required to be made by the Company are referred to herein as a “Reimbursement Payment”. Available Operating Funds means the sum of (i) the Company’s net investment company taxable income (including net short-term capital gains reduced by net long-term capital losses), (ii) the Company’s net capital gains (including the excess of net long-term capital gains over net short-term capital losses) and (iii) dividends and other distributions paid to the Company on account of investments in portfolio companies (to the extent such amounts listed in clause (iii) are not included under clauses (i) and (ii) above).
The Expense Support Agreement terminated by its own terms on October 28, 2021. The Company’s obligation to make Reimbursement Payments survived the termination of the Expense Support Agreement and may be made for a period of up to three years, in accordance with the terms of the Expense Support Agreement.  The Company’s obligation to make a Reimbursement Payment becomes a liability of the Company on the last business day of the applicable calendar quarter. As of March 31, 2023 and 2022, there are no amounts subject to the Reimbursement Payment obligation. As of March 31, 2023 and 2022, there was no unreimbursed Expense Payments remaining. For the three months ended March 31, 2023 and 2022, the Adviser made no Expense Payments and the Company made no Reimbursement Payments related to Expense Payments by the Adviser.

The significant unobservable input used in the yield analysis is the discount rate based on comparable market yields. The significant unobservable input used for market quotations are broker quoted prices provided by independent pricing services. The significant unobservable input used under the market approach is the performance multiple. Significant increases in discount rates would result in a significantly lower fair value measurement. Significant decreases in quoted prices or performance multiples would result in a significantly lower fair value measurement.

Shares Issued
The Company has the authority to issue an unlimited number of shares at $0.001 per share par value.  
On October 28, 2021, the Company priced its IPO, issuing 9,180,000 of its common shares of beneficial interest at a public offering price of $26.15 per share. Net of underwriting fees, the Company received net cash proceeds, before offering expenses, of $230.6 million. On November 4, 2021, the underwriters exercised their option to purchase an additional 1,377,000 shares of common shares, which resulted in net cash proceeds, before offering expenses, of $33.8 million. The Company’s common shares began trading on the NYSE under the symbol “BXSL” on October 28, 2021.
The Company may from time to time issue shares of our common shares of beneficial interest through "at the market" offerings. We may be party to equity distribution agreements with banks (the “Equity Distribution Agreements”). The Equity Distribution Agreements provide that we may from time to time issue and sell, by means of “at the market” offerings, up to $200 million shares of our common shares of beneficial interest. Subject to the terms and conditions of the Equity Distribution Agreements, sales of common shares of beneficial interest, if any, may be made in transactions that are deemed to be “at the market” offerings as defined in Rule 415(a)(4) under the Securities Act.
There have been no shares issued for the three months ended March 31, 2023 and 2022, other than those issued through the Company's dividend reinvestment program.

Dividend Reinvestment
The Company has adopted a dividend reinvestment plan (“DRIP”), pursuant to which it reinvests all cash dividends declared by the Board on behalf of its shareholders who do not elect to receive their dividends in cash. As a result, if the Board and the Company declares, a cash dividend or other distribution, then the Company’s shareholders who have not opted out of its dividend reinvestment plan will have their cash distributions automatically reinvested in additional shares as described below, rather than receiving the cash dividend or other distribution. Starting from the consummation of the IPO, the number of shares to be issued to a shareholder is determined by dividing the total dollar amount of the cash dividend or distribution payable to a shareholder by the market price per common share at the close of regular trading on the NYSE on the payment date of a distribution, or if no sale is reported for such day, the average of the reported bid and ask prices. However, if the market price per share on the payment date of a cash dividend or distribution exceeds the most recently computed NAV per share, the
Company will issue shares at the greater of (i) the most recently computed NAV per share and (ii) 95% of the current market price per share (or such lesser discount to the current market price per share that still exceeded the most recently computed NAV per share). For example, if the most recently computed NAV per share is $25.00 and the market price on the payment date of a cash dividend is $24.00 per share, the Company will issue shares at $24.00 per share. If the most recently computed NAV per share is $25.00 and the market price on the payment date of a cash dividend is $27.00 per share, the Company will issue shares at $25.65 per share (95% of the current market price). If the most recently computed NAV per share is $25.00 and the market price on the payment date of a cash dividend is $26.00 per share, the Company will issue shares at $25.00 per share.
Shareholders who receive distributions in the form of shares will generally be subject to the same U.S. federal, state and local tax consequences as if they received cash distributions; however, since their cash distributions will be reinvested, those shareholders will not receive cash with which to pay any applicable taxes. The Company intends to use newly issued shares to implement the plan.
Pursuant to our dividend reinvestment plan, the following table summarizes the amounts and shares issued to shareholders who have not opted out of the Company’s DRIP during the three months ended March 31, 2023 (dollars in thousands except share amounts):

Share Repurchase Plan

In October 18, 2021, the Board approved a share repurchase plan (the “Company 10b5-1 Plan”), to acquire up to approximately $262 million (representing the net proceeds from the IPO) in the aggregate of our common shares at prices below our NAV per share over a specified period, in accordance with the guidelines specified in Rule 10b-18 and Rule 10b5-1 of the Exchange Act. The Company 10b5-1 Plan terminated by its own terms in November 2022.

In February 2023, the Board authorized a share repurchase plan, under which we may repurchase up to $250 million in the aggregate of our outstanding common shares in the open market at prices below our NAV per share for a one-year term, in accordance with the guidelines specified in Rule 10b-18 of the Exchange Act (the “Company 10b-18 Plan”, and together with the Company 10b5-1 Plan, the “Share Repurchase Plans”).

For the three months ended March 31, 2023 and 2022, the Company did not repurchase any of its shares under the Share Repurchase Plans.

Shareholder Transfer Restrictions

For shareholders who held common shares prior to the IPO without the consent of the Adviser:

•prior to January 3, 2022, a shareholder was not permitted to transfer (whether by sale, gift, merger, by operation of law or otherwise), exchange, assign, pledge, hypothecate or otherwise dispose of or encumber any common share held by such shareholder prior to the IPO (and any DRIP shares received with respect to such common shares);

•prior to March 1, 2022, a shareholder was not permitted to transfer (whether by sale, gift, merger, by operation of law or otherwise), exchange, assign, pledge, hypothecate or otherwise dispose of or encumber 90% of the common shares held by such shareholder prior to the IPO (and any DRIP shares received with respect to such common shares);
•prior to May 1, 2022, a shareholder was not permitted to transfer (whether by sale, gift, merger, by operation of law or otherwise), exchange, assign, pledge, hypothecate or otherwise dispose of or encumber 75% of the common shares held by such shareholder prior to the IPO (and any DRIP shares received with respect to such common shares); and

•prior to July 1, 2022, a shareholder was not permitted to transfer (whether by sale, gift, merger, by operation of law or otherwise), exchange, assign, pledge, hypothecate or otherwise dispose of or encumber 50% of the common shares held by such shareholder prior to the date of the IPO (and any DRIP shares received with respect to such common shares).

This means that, as a result of these transfer restrictions, without the consent of the Adviser, a shareholder who owned 100 common shares on the date of the IPO could not sell any of such shares until January 3, 2022; prior to March 1, 2022, such shareholder could only sell up to 10 of such shares; prior to May 1, 2022, such shareholder could only sell up to 25 of such shares; prior to July 1, 2022, such shareholder could only sell up to 50 of such shares; and after July 1, 2022, such shareholder could sell all of such shares. Consent by the Adviser to waive any of the foregoing transfer restrictions is subject to the consent of the representatives on behalf of the underwriters in the IPO. In addition, the Company’s trustees have agreed for a period of 180 days after the date of the IPO and the Company’s executive officers who are not trustees have agreed for a period of 180 days after the date of the IPO, not to transfer (whether by sale, gift, merger, by operation of law or otherwise) their common shares without the prior written consent of the representatives on behalf of the underwriters in the IPO, subject to certain exceptions.

Blackstone Secured Lending Fund (together with its consolidated subsidiaries, the “Company”), is a Delaware statutory trust formed on March 26, 2018, and structured as an externally managed, non-diversified closed-end management investment company. On October 26, 2018, the Company elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (together with the rules and regulations promulgated thereunder, the “1940 Act”). In addition, the Company elected to be treated for U.S. federal income tax purposes, and intends to qualify annually, as a regulated investment company (a “RIC”), under Subchapter M of the Internal Revenue Code of 1986, as amended (together with the rules and regulations promulgated thereunder, the “Code”).

The Company is externally managed by Blackstone Credit BDC Advisors LLC (the “Adviser”) an affiliate of Blackstone Alternative Credit Advisors LP (the “Administrator” and, collectively with its affiliates in the credit-focused business of Blackstone Inc. (“Blackstone”), “Blackstone Credit,” which, for the avoidance of doubt, excludes Harvest Fund Advisors LLC and Blackstone Insurance Solutions). The Administrator provides certain administrative and other services necessary for the Company to operate pursuant to an administration agreement (the “Administration Agreement”).  Blackstone Credit is part of the credit-focused platform of Blackstone and is the primary part of its Credit & Insurance reporting segment.

The Company’s investment objectives are to generate current income and, to a lesser extent, long-term capital appreciation. The Company seeks to achieve its investment objectives primarily through originated loans and other securities, including syndicated loans, of private U.S. companies, typically in the form of first lien senior secured and unitranche loans (including first-out/last-out loans), and to a lesser extent, second lien, third lien, unsecured and subordinated loans and other debt and equity securities.
Our investment objectives are to generate current income and, to a lesser extent, long-term capital appreciation.
Under normal market conditions, we generally invest at least 80% of our total assets (net assets plus borrowings for investment purposes) in secured debt investments and our portfolio is composed primarily of first lien senior secured and unitranche loans. To a lesser extent, we have and may continue to also invest in second lien, third lien, unsecured or subordinated loans and other debt and equity securities. In limited instances we may retain the “last out” portion of a first-lien loan. In such cases, the “first out” portion of the first lien loan would receive priority with respect to payment over our “last out” position. In exchange for the higher risk of loss associated with such “last out” portion, we would earn a higher rate of interest than the “first out” position." We do not currently focus on investments in issuers that are distressed or in need of rescue financing.
Financial Condition, Liquidity and Capital Resources
Our liquidity and capital resources are generated primarily from cash flows from interest, dividends and fees earned from our investments and principal repayments, our credit facilities, debt securitization transactions, and other secured and unsecured debt. We may also generate cash flow from operations, future borrowings and future offerings of securities including public and/or private issuances of debt and/or equity securities through both registered offerings and private offerings. The primary uses of our cash and cash equivalents are for (i) originating loans and purchasing senior secured debt investments, (ii) funding the costs of our operations (including fees paid to our Adviser and expense reimbursements paid to our Administrator), (iii) debt service, repayment and other financing costs of our borrowings and (iv) cash distributions to the holders of our shares.
As of both March 31, 2023 and December 31, 2022, we had 4 revolving credit facilities outstanding and we had 5 unsecured bonds outstanding. We may from time to time enter into additional credit facilities, increase the size of our existing credit facilities or issue further debt securities. Any such incurrence or issuance would be subject to prevailing market conditions, our liquidity requirements, contractual and regulatory restrictions and other factors. In accordance with the 1940 Act, with certain limited exceptions, we are only allowed to incur borrowings, issue debt securities or issue preferred stock, if immediately after the borrowing or issuance, the ratio of total assets (less total liabilities other than indebtedness) to total indebtedness plus preferred stock, is at least 150%. As of March 31, 2023 and December 31, 2022, we had an aggregate amount of $5,484.6 million and $5,563.0 million of senior securities outstanding and our asset coverage ratio was 176.4% and 174.8%, respectively. We seek to carefully consider our unfunded commitments for the purpose of planning our ongoing financial leverage. Further, we maintain sufficient borrowing capacity within the 150% asset coverage limitation to cover any outstanding unfunded commitments we are required to fund.
Cash and cash equivalents as of March 31, 2023, taken together with our $1,065.4 million of available capacity under our credit facilities (subject to borrowing base availability) is expected to be sufficient for our investing activities and to conduct our operations in the near term. Additionally, we held $199.7 million of Level 2 debt investments as of March 31, 2023, which could provide additional liquidity if necessary. Although we have historically been able to obtain sufficient borrowing capacity, a deterioration in economic conditions or any other negative economic developments could restrict our
access to financing in the future. We may not be able to find new financing for future investments or liquidity needs and, even if we are able to obtain such financing, such financing may not be on as favorable terms as we have previously obtained. These factors may limit our ability to make new investments and adversely impact our results of operations.As of March 31, 2023, we had $103.0 million in cash and cash equivalents. During the three months ended March 31, 2023, cash provided by operating activities was $155.9 million, primarily as a result of proceeds from sale of investments and principal repayment of $109.1 million partially offset by purchase of investments of $102.3 million. Cash used in financing activities was $186.8 million during the period, which was primarily as a result of net repayments on our credit facilities of $92.7 million and dividends paid in cash of $91.8 million

Item 3. Quantitative and Qualitative Disclosures About Market Risk.
Uncertainty with respect to the economic conditions has introduced significant volatility in the financial markets, and the effect of the volatility could materially impact our market risks. We are subject to financial market risks, including valuation risk, interest rate risk and inflation risk. Our exposure to market risk has not materially changed from what was previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

Accounting Policies [Abstract]  
Basis of Presentation
Basis of Presentation
The consolidated financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States (“GAAP”).  As an investment company, the Company applies the accounting and reporting guidance in Accounting Standards Codification (“ASC”) Topic 946, Financial Services – Investment Companies (“ASC 946”) issued by the Financial Accounting Standards Board (“FASB”).
The interim consolidated financial statements have been prepared in accordance with GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 6 and Article 10 of Regulation S-X. Accordingly, certain disclosures accompanying the annual consolidated financial statements prepared in accordance with GAAP are omitted.  In the opinion of management, all adjustments considered necessary for the fair presentation of the consolidated financial statements for the interim period presented, have been included. The current period’s results of operations will not necessarily be indicative of results that ultimately may be achieved for the fiscal year ending December 31, 2023.
All intercompany balances and transactions have been eliminated.
Certain prior period information has been reclassified to conform to the current period presentation.
Use of Estimates
Use of Estimates
The preparation of consolidated financial statements in conformity with 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 consolidated financial statements. Such amounts could differ from those estimates and such differences could be material. Assumptions and estimates regarding the valuation of investments involve a higher degree of
judgment and complexity and these assumptions and estimates may be significant to the consolidated financial statements. Actual results may ultimately differ from those estimates.
Consolidation
Consolidation
As provided under ASC 946, the Company will not consolidate its investment in a company other than an investment company subsidiary or a controlled operating company whose business consists of providing services to the Company.
The Company consolidated the results of the Company’s wholly-owned subsidiaries which are considered to be investment companies. As of March 31, 2023 and December 31, 2022, the Company's consolidated subsidiaries were BGSL Jackson Hole Funding LLC (“Jackson Hole Funding”), BGSL Breckenridge Funding LLC (“Breckenridge Funding”), BGSL Big Sky Funding LLC (“Big Sky Funding”) and BGSL Investments LLC (“BGSL Investments”)
Cash and Cash Equivalents
Cash and Cash Equivalents
Cash and cash equivalents consist of demand deposits and highly liquid investments, such as money market funds, with original maturities of three months or less. Cash and cash equivalents are carried at cost, which approximates fair value. The Company deposits its cash and cash equivalents with financial institutions and, at times, may exceed the Federal Deposit Insurance Corporation insured limit.
Investments/Receivables/Payables From Investments Sold/Purchased
Investments
Investment transactions are recorded on a trade date basis.
Realized gains or losses are measured by the difference between the net proceeds received (excluding prepayment fees, if any) and the amortized cost basis of the investment using the specific identification method without regard to unrealized gains or losses previously recognized, and include investments charged off during the period, net of recoveries, and is recorded within Net Realized gain (loss) on the Consolidated Statements of Operations.
The net change in unrealized gains or losses primarily reflects the change in investment values, including the reversal of previously recorded unrealized gains or losses with respect to investments realized during the period, and is recorded within Net unrealized appreciation (depreciation) on the Consolidated Statements of Operations.
Valuation of Investments
The Company is required to report its investments, including those for which current market values are not readily available, at fair value.
GAAP for an investment company requires investments to be recorded at fair value. The Company values its investments in accordance with ASC 820, Fair Value Measurements (“ASC 820”), which defines fair value as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the applicable measurement date, and Rule 2a-5 under the 1940 Act.
Fair value is based on observable market prices or parameters or derived from such prices or parameters when such quotations are readily available. In accordance with Rule 2a-5 under the 1940 Act, a market quotation is "readily available" only when it is a quoted price (unadjusted) in active markets for identical instruments that a fund can access at the measurement date, provided that such a quotation is not considered to be readily available if it is not reliable. The Company utilizes mid-market pricing (i.e., mid-point of average bid and ask prices) to value these investments. These market quotations are obtained from independent pricing services, if available; otherwise generally from at least two principal market makers or primary market dealers.
Where prices or inputs are not available or, in the judgment of the Board, not reliable, valuation techniques based on the facts and circumstances of the particular investment will be utilized. These valuation approaches involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the investments or market and the investments’ complexity. In the absence of observable, reliable market prices, the Company values its investments using various valuation methodologies applied on a consistent basis.
An enterprise value (“EV”) analysis is generally performed to determine the value of equity investments, control debt investments and non-control debt investments that are credit-impaired, and to determine if debt investments are credit impaired.
The Adviser will generally utilize approaches including the market approach, the income approach or both approaches, as appropriate, when calculating EV. The primary method for determining EV for non-control investments, and control investments without reliable projections, uses a multiple analysis whereby appropriate multiples are applied to the portfolio company’s earnings before interest, taxes, depreciation and amortization (“EBITDA”) or another key financial metric (e.g., such as revenues, cash flows or net income) (“Performance Multiple”). Performance Multiples are typically determined based upon a review of publicly traded comparable companies and market comparable transactions, if any. The second method for determining EV (and primary method for control investments with reliable projections) uses a discounted cash flow analysis whereby future expected cash flows and the anticipated terminal value of the portfolio company are discounted to determine a present value using estimated discount rates. The income approach is generally used when the Adviser has visibility into the long term projected cash flows of a portfolio company.
If debt investments are credit-impaired, which occurs when there is insufficient coverage under the enterprise value analysis through the respective investment’s position in the capital structure, the Adviser generally uses the enterprise value “waterfall” approach or a recovery method (if a liquidation or restructuring is deemed likely) to determine fair value. For debt investments that are not determined to be credit-impaired, the Adviser generally uses a market interest rate yield analysis to determine fair value. To determine fair value using a yield analysis, the expected cash flows are projected based on the contractual terms of the debt security and discounted back to the measurement date based on a market yield. A market yield is determined based upon an assessment of current and expected market yields for similar investments and risk profiles. The Company considers the current contractual interest rate, the maturity and other terms of the investment relative to risk of the company and the specific investment. A key determinant of risk, among other things, is the leverage through the investment relative to the enterprise value of the portfolio company. As debt investments held by the Company are substantially illiquid with no active transaction market, the Company depends on primary market data, including newly funded transactions, as well as secondary market data with respect to high yield debt instruments and syndicated loans, as inputs in determining the appropriate market yield, as applicable. The fair value of loans with call protection is generally capped at par plus applicable prepayment premium in effect at the measurement date.
ASC 820 prioritizes the use of observable market prices derived from such prices. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The levels used for classifying investments are not necessarily an indication of the risk associated with investing in these securities. The three levels of the fair value hierarchy are as follows:
•Level 1: Inputs to the valuation methodology are quoted prices available in active markets for identical instruments as of the reporting date. The types of financial instruments included in Level 1 include unrestricted securities, including equities and derivatives, listed in active markets.
•Level 2:  Inputs to the valuation methodology are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date. The types of financial instruments in this category include less liquid and restricted securities listed in active markets, securities traded in other than active markets, government and agency securities and certain over-the-counter derivatives where the fair value is based on observable inputs.
•Level 3:  Inputs to the valuation methodology are unobservable and significant to overall fair value measurement. The inputs into the determination of fair value require significant management judgment or estimation. Financial instruments that are included in this category include debt and equity investments in privately held entities, collateralized loan obligations (“CLOs”) and certain over-the-counter derivatives where the fair value is based on unobservable inputs.
In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment’s level within the fair value hierarchy is based on the lowest level of input that is significant to the overall fair value measurement. The Adviser’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment. Transfers between levels, if any, are recognized at the beginning of the quarter in which the transfer occurs.
The Company evaluates the source of the inputs, including any markets in which its investments are trading (or any markets in which securities with similar attributes are trading), in determining fair value. When an investment is valued based on prices provided by reputable dealers or pricing services (that is, broker quotes), the Company subjects those prices to various criteria in making the determination as to whether a particular investment would qualify for treatment as a Level 2 or Level 3 investment.
Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of the Company’s investments may fluctuate from period to period, and these differences could be material. Additionally, the fair value of the Company’s investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that the Company may ultimately realize. Further, such investments are generally subject to legal and other restrictions on resale or otherwise are less liquid than publicly traded securities. If the Company was required to liquidate a portfolio investment in a forced or liquidation sale, it could realize significantly less than the value at which the Company has recorded it. In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the unrealized gains or losses reflected in the valuations currently assigned.  See “Item 2. Management’s Discussion and Analysis of Financial Conditions and Results of Operations—Critical Accounting Estimates.”
Receivables/Payables From Investments Sold/Purchased
Receivables/payables from investments sold/purchased consist of amounts receivable to or payable by the Company for transactions that have not settled at the reporting date.
Derivative Instruments/Forward Purchase Agreement
Derivative Instruments

The Company recognizes all derivative instruments as assets or liabilities at fair value in its consolidated financial statements. Derivative contracts entered into by the Company are not designated in hedge accounting relationships and all changes in fair value are recognized through current period gains or losses.
In the normal course of business, the Company has commitments and risks resulting from its investment transactions, which may include those involving derivative instruments. Derivative instruments are measured in terms of the notional contract amount and derive their value based upon one or more underlying instruments. While the notional amount gives some indication of the Company’s derivative activity, it generally is not exchanged, but is only used as the basis on which interest and other payments are exchanged. Derivative instruments are subject to various risks similar to non-derivative instruments including market, credit, liquidity, and operational risks. The Company manages these risks on an aggregate basis as part of its risk management process.
Forward Purchase Agreement
Forward purchase agreements are recognized at fair value through current period gains or losses on the date on which the contract is entered into and are subsequently re-measured at fair value. All forward purchase agreements are carried as assets when fair value is positive and as liabilities when fair value is negative.  A forward purchase agreement is derecognized when the obligation specified in the contract is discharged, canceled or expired.
Foreign Currency Transactions
Foreign Currency Transactions

Amounts denominated in foreign currencies are translated into U.S. dollars on the following basis: (i) investments and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates effective on the last business day of the period; and (ii) purchases and sales of investments, borrowings and repayments of such borrowings, income, and expenses denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates prevailing on the transaction dates.
The Company includes net changes in fair values on investments held resulting from foreign exchange rate fluctuations in translation of assets and liabilities in foreign currencies on the Consolidated Statements of Operations, if any. Foreign security and currency translations may involve certain considerations and risks not typically associated with investing in U.S. companies and U.S. government securities. These risks include, but are not limited to, currency fluctuations and revaluations and future adverse political, social and economic developments, which could cause investments in foreign markets to be less liquid and prices more volatile than those of comparable U.S. companies or U.S. government securities
Revenue Recognition
Revenue Recognition
Interest Income
Interest income is recorded on an accrual basis and includes the accretion of discounts and amortizations of premiums.  Discounts from and premiums to par value on debt investments purchased are accreted/amortized into interest income over the life of the respective security using the effective interest method.  The amortized cost of debt investments
represents the original cost, including loan origination fees and upfront fees received that are deemed to be an adjustment to yield, adjusted for the accretion of discounts and amortization of premiums, if any. Upon prepayment of a loan or debt security, any prepayment premiums, unamortized upfront loan origination fees and unamortized discounts are recorded as interest income in the current period. For the three months ended March 31, 2023 and 2022, the Company recorded $0.4 million and $1.0 million, respectively, in non-recurring interest income (e.g., prepayment premiums, accelerated accretion of upfront loan origination fees and unamortized discounts).
PIK Income
The Company has loans in its portfolio that contain payment-in-kind (“PIK”) provisions.  PIK represents interest that is accrued and recorded as interest income at the contractual rates, increases the loan principal on the respective capitalization dates, and is generally due at maturity.  Such income is included in Payment-in-kind interest income in the Consolidated Statements of Operations.  If at any point the Company believes PIK is not expected to be realized, the investment generating PIK will be placed on non-accrual status. When a PIK investment is placed on non-accrual status, the accrued, uncapitalized interest is generally reversed through Payment-in-kind interest income. To satisfy the Company's annual RIC distribution requirements, this non-cash source of income must be included in determining the amounts to be paid out to shareholders in the form of dividends, even though the Company has not yet collected cash.
Dividend Income
Dividend income on preferred equity securities is recorded on the accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly-traded portfolio companies.
Fee Income
The Company may receive various fees in the ordinary course of business such as structuring, consent, waiver, amendment, syndication and other miscellaneous fees as well as fees for managerial assistance rendered by the Company to the portfolio companies. Such fees are recognized as income when earned or the services are rendered.
Non-Accrual Income
Loans are generally placed on non-accrual status when there is reasonable doubt whether principal or interest will be collected in full. Accrued interest is generally reversed when a loan is placed on non-accrual status. Additionally, any original issue discount and market discount are no longer accreted to interest income as of the date the loan is placed on non-accrual status.  Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding collectability. Non-accrual loans are restored to accrual status when past due principal and interest is paid current and, in management’s judgment, are likely to remain current. Management may make exceptions to this treatment and determine to not place a loan on non-accrual status if the loan has sufficient collateral value and is in the process of collection.
Organization Expenses and Offering Expenses Organization Expenses and Offering ExpensesThe Company records expenses related to public equity offerings as a reduction of capital upon completion of an offering of registered securities. The costs associated with any renewals of a shelf registration statement will be expensed as incurred

Deferred Financing Costs and Debt Issuance Costs
Deferred financing and debt issuance costs represent fees and other direct incremental costs incurred in connection with the Company’s borrowings.  These expenses are deferred and amortized into interest expense over the life of the related debt instrument. Deferred financing costs related to revolving credit facilities are presented separately as an asset on the Company’s Consolidated Statements of Assets and Liabilities.  Debt issuance costs related to any issuance of installment debt or notes are presented net against the outstanding debt balance of the related security.
Income Taxes
Income Taxes
The Company has elected to be treated as a BDC under the 1940 Act.  The Company also has elected to be treated as a RIC under the Code. So long as the Company maintains its status as a RIC, it generally will not pay corporate-level U.S. federal income taxes on any ordinary income or capital gains that it distributes at least annually to its shareholders as dividends. Rather, any tax liability related to income earned and distributed by the Company would represent obligations of the Company’s investors and would not be reflected in the consolidated financial statements of the Company.
The Company evaluates tax positions taken or expected to be taken in the course of preparing its consolidated financial statements to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are reserved and recorded as a tax benefit or expense in the current year. All penalties and interest associated with income taxes are included in income tax expense. Conclusions regarding tax positions are subject to review and may be adjusted at a later date based on factors including, but not limited to, on-going analyses of tax laws, regulations and interpretations thereof.
To qualify for and maintain qualification as a RIC, the Company must, among other things, meet certain source-of-income and asset diversification requirements. In addition, to qualify for RIC tax treatment, the Company must distribute to its shareholders, for each taxable year, at least 90% of the sum of (i) its “investment company taxable income” for that year (without regard to the deduction for dividends paid), which is generally its ordinary income plus the excess, if any, of its realized net short-term capital gains over its realized net long-term capital losses and (ii) its net tax-exempt income.
In addition, based on the excise tax distribution requirements, the Company is subject to a 4% nondeductible federal excise tax on undistributed income unless the Company distributes in a timely manner in each taxable year an amount at least equal to the sum of (i) 98% of its ordinary income for the calendar year, (ii) 98.2% of capital gain net income (both long-term and short-term) for the one-year period ending October 31 in that calendar year and (iii) any income realized, but not distributed, in prior years. For this purpose, however, any ordinary income or capital gain net income retained by the Company that is subject to corporate income tax is considered to have been distributed.
Distributions
Distributions
To the extent that the Company has taxable income available, the Company intends to make quarterly distributions to its shareholders. Distributions to shareholders are recorded on the record date. All distributions will be paid at the discretion of the Board and will depend on the Company’s earnings, financial condition, maintenance of the Company's tax treatment as a RIC, compliance with applicable BDC regulations and such other factors as the Board may deem relevant from time to time.
Recent Accounting Pronouncements
Recent Accounting Pronouncements
In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848),” which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts, hedging relationships, and other transactions that reference London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848), which expanded the scope of Topic 848 to include derivative instruments impacted by discounting transition. ASU 2020-04 and ASU 2021-01 are effective for all entities through December 31, 2022. The expedients and exceptions provided by the amendments do not apply to contract modifications and hedging relationships entered into or evaluated after December 31, 2022, except for hedging transactions as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. In December 2022, the FASB issued ASU No. 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which deferred the sunset day of this guidance to December 31, 2024. The Company is currently evaluating the impact on its consolidated financial statements.
Fair Value Measurements The significant unobservable input used in the yield analysis is the discount rate based on comparable market yields. The significant unobservable input used for market quotations are broker quoted prices provided by independent pricing services. The significant unobservable input used under the market approach is the performance multiple. Significant increases in discount rates would result in a significantly lower fair value measurement. Significant decreases in quoted prices or performance multiples would result in a significantly lower fair value measurement.

(1)The per share data was derived by using the weighted average shares outstanding during the period.
(2)The per share data for distributions was derived by using the actual shares outstanding at the date of the relevant transactions (refer to Note 8).
(3)Total return is calculated as the change in NAV per share during the period, plus distributions per share (assuming dividends and distributions are reinvested in accordance with the Company's dividend reinvestment plan) divided by the beginning NAV per share. Total return does not include sales load.
(4)Total return based on market value is calculated as the change in market value per share during the respective periods, taking into account distributions, if any, reinvested in accordance with the Company’s dividend reinvestment plan.
(5)Amounts are annualized except for expense support amounts relating to organizational costs and management fee and income based incentive fee waivers by the Adviser (refer to Note 3). For the three months ended March 31, 2023 and 2022, the ratio of total operating expenses to average net assets was 11.94% and 8.23%, respectively, on an annualized basis, excluding the effect of expense support/(recoupment) and management fee and income based incentive fee waivers by the Adviser which represented (0.25)% and (0.84)%, respectively, of average net assets.
