CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
This report contains forward-looking statements that involve substantial risks and uncertainties. Such statements involve known and unknown risks, uncertainties and other factors and undue reliance should not be placed thereon. These forward-looking statements are not historical facts, but rather are based on current expectations, estimates and projections about Blackstone Secured Lending Fund (together, with its consolidated subsidiaries, the “Company,” “we” “us” or “our”), our current and prospective portfolio investments, our industry, our beliefs and opinions, and our assumptions. Words such as “anticipates,” “expects,” “intends,” “plans,” “will,” “may,” “continue,” “believes,” “seeks,” “estimates,” “would,” “could,” “should,” “targets,” “projects,” “outlook,” “potential,” “predicts” and variations of these words and similar expressions are intended to identify forward-looking statements. These statements are not guarantees of future performance and are subject to risks, uncertainties and other factors, some of which are beyond our control and difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements, including without limitation:
our future operating results;
our business prospects and the prospects of the companies in which we may invest;
the impact of the investments that we expect to make;
our ability to raise sufficient capital and buy back shares to execute our investment strategy;
general economic, logistical and political trends and other external factors, including the current novel coronavirus (COVID-19) pandemic, related COVID-19 variants, inflation and supply chain and labor market disruptions;
turmoil in Ukraine and Russia and the potential for volatility in energy prices and its impact on the industries in which we invest;
the ability of our portfolio companies to achieve their objectives;
our current and expected financing arrangements and investments;
changes in the general interest rate environment;
the adequacy of our cash resources, financing sources and working capital;
the timing and amount of cash flows, distributions and dividends, if any, from our portfolio companies;
our contractual arrangements and relationships with third parties;
actual and potential conflicts of interest with Blackstone Credit BDC Advisors LLC (the “Adviser”) or any of its affiliates;
the dependence of our future success on the general economy and its effect on the industries in which we may invest;
our use of financial leverage;
our business prospects and the prospects of our portfolio companies, including our and their ability to effectively respond to challenges posed by the COVID-19 pandemic;
the ability of the Adviser to source suitable investments for us and to monitor and administer our investments;
the ability of the Adviser or its affiliates to attract and retain highly talented professionals;
our ability to qualify for and maintain our qualification as a regulated investment company and as a business development company (“BDC”);
the impact on our business of U.S. and international financial reform legislation, rules and regulations;
the effect of changes to tax legislation and our tax position; and
the tax status of the enterprises in which we may invest.
Although we believe that the assumptions on which these forward-looking statements are based are reasonable, any of those assumptions could prove to be inaccurate, and as a result, the forward-looking statements based on those assumptions also could be inaccurate. In light of these and other uncertainties, the inclusion of any projection or forward-looking statement in this report should not be regarded as a representation by us that our plans and objectives will be achieved. These risks and uncertainties include those described or identified in the section entitled “Risk Factors” in Part I, Item 1A of our annual report on Form 10-K for the year ended December 31, 2021 as updated by the Company's periodic filings with the Securities and Exchange Commission. These projections and forward-looking statements apply only as of the date of this report. Moreover, we assume no duty and do not undertake to update the forward-looking statements, except as required by applicable law. Because we are an investment company, the forward-looking statements and projections contained in this report are excluded from the safe harbor protection provided by Section 21E of the U.S. Securities Exchange Act of 1934, as amended (the “1934 Act”).

(1)Unless otherwise indicated, issuers of debt and equity investments held by the Company (which such term “Company” shall include the Company’s consolidated subsidiaries for purposes of this Consolidated Schedule of Investments) are denominated in dollars. All debt investments are income producing unless otherwise indicated. All equity investments are non-income producing unless otherwise noted. Certain portfolio company investments are subject to contractual restrictions on sales. The total par amount is presented for debt investments, while the number of shares or units owned is presented for equity investments. Each of the Company’s investments is pledged as collateral, under one or more of its credit facilities unless otherwise indicated.
(2)Variable rate loans to the portfolio companies bear interest at a rate that is determined by reference to either LIBOR (“L”), Canadian Dollar Offered Rate (“CDOR” or “C”), Sterling Overnight Interbank Average Rate (“SONIA” or “S”), Euro Interbank Offer Rate (“Euribor” or “E”), Secured Overnight Financing Rate (“SOFR”), or an alternate base rate (commonly based on the Federal Funds Rate (“F”) or the U.S. Prime Rate (“P”)), which generally resets periodically. For each loan, the Company has indicated the reference rate used and provided the spread and the interest rate in effect as of September 30, 2022. Variable rate loans typically include an interest reference rate floor feature. As of September 30, 2022, 94.3% of the portfolio at fair value had a base rate floor above zero. For each such loan, the Company has provided the interest rate in effect on the date presented.
(3)The cost represents the original cost adjusted for the amortization of discounts and premiums, as applicable, on debt investments using the effective interest method in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).
(4)These investments were valued using unobservable inputs and are considered Level 3 investments. Fair value was determined in good faith by or under the direction of the Board of Trustees (the “Board”) (see Note 2 and Note 5), pursuant to the Company’s valuation policy.
(5)These debt investments are not pledged as collateral under any of the Company's credit facilities. For other debt investments that are pledged to the Company's credit facilities, a single investment may be divided into parts that are individually pledged as collateral to separate credit facilities.
(6)The investment is not a qualifying asset under Section 55(a) of the Investment Company Act of 1940, as amended (together with the rules and regulations promulgated thereunder, the “1940 Act”). The Company may not acquire any non-qualifying asset unless, at the time of acquisition, qualifying assets represent at least 70% of the Company’s total assets. As of September 30, 2022, non-qualifying assets represented 10.7% of total assets as calculated in accordance with regulatory requirements.
(7)Position or portion thereof is an unfunded loan commitment, and no interest is being earned on the unfunded portion, although the investment may be subject to unused commitment fees. Negative cost and fair value results from unamortized fees, which are capitalized to the investment cost. The unfunded loan commitment may be subject to a commitment termination date that may expire prior to the maturity date stated. See below for more information on the Company’s unfunded commitments:

(1)Unless otherwise indicated, issuers of debt and equity investments held by the Company are denominated in dollars. All debt investments are income producing unless otherwise indicated. All equity investments are non-income producing unless otherwise noted. Certain portfolio company investments are subject to contractual restrictions on sales. The total par amount is presented for debt investments, while the number of shares or units owned is presented for equity investments. Each of the Company’s investments is pledged as collateral, under one or more of its credit facilities unless otherwise indicated
(2)Variable rate loans to the portfolio companies bear interest at a rate that is determined by reference to either L, CDOR or C, SONIA or S, Euribor or E, SOFR, or an alternate base rate (commonly based on the F or the P), which generally resets periodically. For each loan, the Company has indicated the reference rate used and provided the spread and the interest rate in effect as of December 31, 2021. Variable rate loans typically include an interest reference rate floor feature. As of December 31, 2021, 93.9% of the debt portfolio at fair value had an interest rate floor above zero.
(3)The cost represents the original cost adjusted for the amortization of discounts and premiums, as applicable, on debt investments using the effective interest method in accordance with U.S. GAAP.
(4)These investments were valued using unobservable inputs and are considered Level 3 investments. Fair value was determined in good faith by or under the direction of the Board of Trustees (see Note 2 and Note 5), pursuant to the Company’s valuation policy.

Notes to Consolidated Financial Statements

(in thousands, unless otherwise indicated, except per share data, percentages and as otherwise noted)
Note 1. 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 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 (the “1940 Act”).  In addition, the Company elected to be treated for U.S. federal income tax purposes, as a regulated investment company (“RIC”), as defined under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). The Company also intends to continue to comply with the requirements prescribed by the Code in order to maintain tax treatment as a RIC.  
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 is externally managed by Blackstone Credit BDC Advisors LLC (the “Adviser”). 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) 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 reporting segment. 
The Company previously conducted a private offering (the “Private Offering”) of its common shares of beneficial interest (i) to accredited investors, as defined in Regulation D under the Securities Act of 1933, as amended (the “1933 Act”), and (ii) in the case of shares sold outside the United States, to persons that are not “U.S. persons,” as defined in Regulation S under the 1933 Act, in reliance on exemptions from the registration requirements of the 1933 Act. At each closing of the Private Offering, each investor made a capital commitment (“Capital Commitment”) to purchase shares of the beneficial interest of the Company pursuant to a subscription agreement entered into with the Company. Investors were required to fund drawdowns to purchase the Company’s shares up to the amount of their Capital Commitments on an as-needed basis each time the Company delivered a notice to investors.

On October 31, 2018, the Company began its initial period of closing on capital commitments (“Initial Closing Period”) which ended on October 31, 2020. The Company commenced its loan origination and investment activities on November 20, 2018, the date of receipt of the initial drawdown from investors in the Private Offering (the “Initial Drawdown Date”). On September 8, 2021, the Company closed on its final outstanding Capital Commitments.
Effective on December 10, 2020, the Company changed its name from “Blackstone / GSO Secured Lending Fund” to “Blackstone Secured Lending Fund.”
On October 28, 2021, the Company closed its initial public offering (“IPO”). See "Note 8. Net Assets" for further details.
Note 2. Significant Accounting Policies
Basis of Presentation
The consolidated financial statements have been prepared on the accrual basis of accounting in accordance with U.S. 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”). U.S. GAAP for an investment company requires investments to be recorded at fair value.
The interim consolidated financial statements have been prepared in accordance with U.S. 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.
35

Table of Contents
Accordingly, certain disclosures accompanying the annual consolidated financial statements prepared in accordance with U.S. GAAP are omitted.  In the opinion of management, all adjustments, consisting solely of normal recurring accruals 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, 2022.
All intercompany balances and transactions have been eliminated.
Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the 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.

As of September 30, 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. 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.
The Company is required to report its investments for which current market values are not readily available at fair value. The Company values its investments in accordance with ASC 820, Fair Value Measurements (“ASC 820”) and Rule 2a-5 under the 1940 Act, which defines fair value as the value of a portfolio investment for which market quotations are not readily available. 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. ASC 820 prioritizes the use of observable market prices derived from such prices over entity-specific inputs.  Due to the inherent uncertainties of valuation, certain estimated fair values may differ significantly from the values that would have been realized had a readily available market quotation for these investments existed, and these differences could be material. See “– Note 5. Fair Value Measurements.”
Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. 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, and otherwise from at least two principal market makers or primary market dealers.  To assess the continuing appropriateness of pricing sources and methodologies, the Adviser regularly performs price verification procedures and issues challenges, as necessary, to independent pricing services or brokers, and any differences are reviewed in accordance with the valuation procedures. The Adviser does not adjust the prices
36

Table of Contents
unless it has a reason to believe market quotations are not reflective of the fair value of an investment.  Examples of events that would cause market quotations to not reflect fair value could include cases when a security trades infrequently or not at all, causing a quoted purchase or sale price to become stale, or in the event of a “fire sale” by a distressed seller.  All price overrides require approval from the Board.
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.  Securities that are not publicly traded or for which market prices are not readily available are valued at fair value as determined in good faith by the Board, based on, among other things, the input of the Adviser, the Audit Committee of the Board (the “Audit Committee”) and independent valuation firms engaged on the recommendation of the Adviser and at the direction of the Board.  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.
The Company’s Board undertakes a multi-step valuation process each quarter in connection with determining the fair value of the Company’s investments for which reliable market quotations are not readily available, or are available but deemed not reflective of the fair value of an investment, which includes, among other procedures, the following:
The valuation process begins with each investment being preliminarily valued by the Adviser’s valuation team in conjunction with the Adviser’s investment professionals responsible for each portfolio investment;
In addition, independent valuation firms engaged by the Board prepare quarter-end valuations of such investments except de minimis investments, as determined by the Adviser. The independent valuation firms provide a final range of values on such investments to the Board and the Adviser. The independent valuation firms also provide analyses to support their valuation methodology and calculations;
The Adviser’s Valuation Committee reviews each valuation recommendation to confirm they have been calculated in accordance with the valuation policy and compares such valuations to the independent valuation firms’ valuation ranges to ensure the Adviser’s valuations are reasonable;
The Adviser’s Valuation Committee makes valuation recommendations to the Audit Committee;
The Audit Committee reviews the valuation recommendations made by the Adviser's Valuation Committee, including the independent valuation firms' quarterly valuations, and once approved, recommends them for approval by the Board; and
The Board reviews the valuation recommendations of the Audit Committee and determines the fair value of each investment in the portfolio in good faith based on the input of the Audit Committee, the Adviser's Valuation Committee and, where applicable, the independent valuation firms and other external service providers.
Valuation of each of the Company's investments will generally be made as described above as of the end of each fiscal quarter. In cases where the Company determines its net asset value (“NAV”) at times other than a quarter end, the Company updates the value of securities with market quotations to the most recent market quotation. For securities without market quotations, non-quarterly valuations will generally be the most recent quarterly valuation unless the Adviser determines that a significant observable change has occurred since the most recent quarter end with respect to the investment (which determination may be as a result of a material event at a portfolio company, material change in market spreads, secondary market transaction in the securities of an investment or otherwise). If the Adviser determines such a change has occurred with respect to one or more investments, the Adviser will determine whether to update the value for each relevant investment using a range of values from an independent valuation firm, where applicable, in accordance with the Company's valuation policy, pursuant to authority delegated by the Board.
As part of the valuation process, the Board takes into account relevant factors in determining the fair value of the Company's investments for which reliable market quotations are not readily available, many of which are loans, including and in combination, as relevant, of: (i) the estimated enterprise value of a portfolio company, (ii) the nature and realizable value of any collateral, (iii) the portfolio company’s ability to make payments based on its earnings and cash flow, (iv) the markets in which the portfolio company does business, (v) a comparison of the portfolio company’s securities to any similar publicly traded securities, and (vi) overall changes in the interest rate environment and the credit markets that may affect the price at which similar investments may be made in the future. When an external event such as a purchase transaction, public offering or subsequent equity or debt sale occurs, the Board, with the assistance of the Adviser, the Audit Committee and independent valuation firms, considers whether the pricing indicated by the external event corroborates its valuation. See Note 5. Fair Value Measurements.
37

Table of Contents
The Board has and will continue to engage independent valuation firms to provide assistance regarding the determination of the fair value of the Company’s portfolio securities for which market quotations are not readily available or are readily available but deemed not reflective of the fair value of the investment each quarter, and the Board may reasonably rely on that assistance. However, the Board is responsible for the ultimate valuation of the portfolio investments at fair value as determined in good faith pursuant to the Company’s valuation policy and a consistently applied valuation process.
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. As of September 30, 2022 and December 31, 2021, the Company had $40.0 million and $142.9 million, respectively, of receivables for investments sold. As of September 30, 2022 and December 31, 2021, the Company had $18.8 million and $36.2 million, respectively, of payables for investments purchased.
Derivative Instruments
The Company recognizes all derivative instruments as assets or liabilities at fair value in its consolidated financial statements. The Company presents changes in fair value 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 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 and nine months ended September 30, 2022, the Company recorded $1.7 million and
38

Table of Contents
$2.0 million, respectively, in non-recurring interest income (e.g., prepayment premiums, accelerated accretion of upfront loan origination fees and unamortized discounts). For the three and nine months ended September 30, 2021, the Company recorded $16.4 million and $41.0 million, respectively, in non-recurring interest income.
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 interest income.  To maintain the Company’s status as a RIC, this non-cash source of income must be paid out to shareholders in the form of dividends, even though the Company has not yet collected cash. For the three and nine months ended September 30, 2022, the Company recorded PIK income of $10.9 million and $30.4 million, respectively. For the three and nine months ended September 30, 2021, the Company recorded PIK income of $1.0 million and $3.3 million, respectively.
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. For the three and nine months ended September 30, 2022, the Company recorded dividend income of $0.0 million and $5.9 million, respectively. For the three and nine months ended September 30, 2021, the Company recorded dividend income of $0.0 million and $0.0 million, respectively.
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. For the three and nine months ended September 30, 2022, the Company recorded fee income of $2.6 million and $4.0 million, respectively. For the three and nine months ended September 30, 2021 the Company recorded fee income of $0.5 million and $5.3 million, respectively.
Non-Accrual Income
Loans are generally placed on non-accrual status when there is reasonable doubt that 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. During 2021, the Company incurred $1.6 million of offering costs relating to its IPO which were charged as a reduction of paid-in-capital.
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
39

Table of Contents
Company’s 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 and nine months ended September 30, 2022, the Company incurred $0.0 million and $1.4 million, respectively, of U.S. federal excise tax. For the three and nine months ended September 30, 2021, the Company incurred $2.2 million and $1.9 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 U.S. 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. The Company is currently evaluating the impact of the adoption of ASU 2020-04 and 2021-01 on its consolidated financial statements.

Note 3. 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 Net Cumulative 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 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 renewed on May 31, 2022, for a one-year period.
The Adviser has implemented a voluntary 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 Fee
Since the completion of the IPO, the management fee pursuant to the Investment Advisory Agreement has been 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 U.S. 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 three most recently completed calendar quarters during the Waiver Period. Amounts waived by the Adviser are not subject to recoupment by the Adviser.
The management fee was calculated for the quarter ended December 31, 2021 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 the calendar quarter before and after the consummation of the IPO.
For the three and nine months ended September 30, 2022, base management fees were $25.4 million and $76.9 million, respectively, of which $6.3 million and $19.2 million, respectively, were waived. For the three and nine months ended
41

Table of Contents
September 30, 2021, base management fees were $15.4 million and $40.4 million, respectively, of which $0.0 million and $0.0 million, respectively, were waived. As of September 30, 2022 and December 31, 2021, $19.0 million and $17.8 million, respectively, was payable to the Adviser relating to management fees.
Incentive Fees
The incentive fee consists 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 fee:
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 as defined in the Investment Advisory Agreement.  Pre-incentive fee net investment income 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 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.
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.

Since the IPO, the Company has paid 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 (including the quarter in which the IPO is consummated) and the eleven preceding calendar quarters (including the quarters prior to the consummation of the IPO) (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.
42

Table of Contents

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:
Since the completion of the IPO, the second part of the incentive fee, a capital gains incentive fee, has been 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 U.S. 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 U.S. 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 and nine months ended September 30, 2022 the Company accrued income based incentive fees of $26.1 million and $68.3 million, respectively, of which $3.7 million and $9.8 million, respectively, were waived. For the three and

nine months ended September 30, 2021 the Company accrued income based incentive fees of $17.0 million and $45.1 million, respectively, of which $0.0 million and $0.0 million, respectively, were waived. As of September 30, 2022 and December 31, 2021, $22.4 million and $19.8 million, respectively, was payable to the Adviser for income based incentive fees.
For the three and nine months ended September 30, 2022, the Company accrued capital gains incentive fees of $(5.4) million and $(8.6) million, respectively. For the three and nine months ended September 30, 2021, the Company accrued capital gains incentive fees of $2.4 million and $14.6 million, respectively. As of September 30, 2022 and December 31, 2021, the Company had accrued capital gains incentive fees of $8.8 million and $17.4 million, respectively, none of which was payable on such date under the Investment Advisory Agreement.
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, and on May 6, 2020, May 6, 2021 and May 6, 2022 it was renewed and approved by the Board and a majority of the Independent Trustees for one-year periods. Unless 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.
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 and nine months ended September 30, 2022 and 2021.
For the three and nine months ended September 30, 2022, the Company incurred $0.7 million and $1.9 million, respectively, in fees under the Administration Agreement, which were recorded in administrative service expenses in the Company’s Consolidated Statements of Operations. For the three and nine months ended September 30, 2021, the Company incurred $0.5 million and $1.6 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 September 30, 2022 and December 31, 2021, $0.7 million and $1.1 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 was 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. The Adviser may elect to pay certain expenses of the Company on the Company’s behalf (each, an “Expense Payment”), provided that no portion of the payment will be used to pay any interest of the Company. Any Expense Payment that the Adviser has committed to pay must be paid by the Adviser to the Company in any
44

Table of Contents
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.
Following any calendar quarter in which Available Operating Funds (as defined below) exceed the cumulative distributions accrued to the Company’s shareholders based on distributions declared with respect to record dates occurring in such calendar quarter (the amount of such excess being hereinafter referred to as “Excess Operating Funds”), the Company shall 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 have been reimbursed. Any payments required to be made by the Company shall be 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).
No Reimbursement Payment for any calendar quarter shall be made if the annualized rate of regular cash distributions declared by the Company on record dates in the applicable calendar quarter of such Reimbursement Payment is less than the annualized rate of regular cash distributions declared by the Company on record dates in the calendar quarter in which the Expense Payment was committed to which such Reimbursement Payment relates. The Company’s obligation to make a Reimbursement Payment shall automatically become a liability of the Company on the last business day of the applicable calendar quarter.
As of September 30, 2022 and 2021, there were no unreimbursed Expense Payments remaining.

Note 5. Fair Value Measurements
The fair value of a financial instrument is 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.  
The fair value hierarchy under ASC 820 prioritizes the inputs to valuation methodology used to measure fair value. 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.
47

Table of Contents
In addition to using the above inputs in investment valuations, the Company applies the valuation policy approved by its Board that is consistent with ASC 820.  Consistent with the valuation policy, 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.
In the absence of independent, reliable market quotes, an enterprise value analysis is typically 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.  Enterprise value (“EV”) means the entire value of the portfolio company to a market participant, including the sum of the values of debt and equity securities used to capitalize the enterprise at a point in time.  When an investment is valued using an EV analysis, the EV of a portfolio company is first determined and allocated over the portfolio company’s securities in order of their preference relative to one another (i.e., “waterfall” allocation).  
If debt investments are credit-impaired, which occurs when there is insufficient coverage under the EV analysis through the respective investment’s position in the capital structure, the Adviser 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 uses a market interest rate yield analysis (discussed below) to determine fair value.
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, which is more common with control investments.  
Subsequently, for non-control debt investments that are not credit-impaired, and where there is an absence of available market quotations, fair value is determined using a yield analysis. 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.

(1)Weighted averages are calculated based on fair value of investments.
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.

Table of Contents
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. 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.
Financial Instruments Not Carried at Fair 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.
In connection with the listing of the Company’s common shares on the NYSE, the Board decided to eliminate any outstanding fractional common shares (the “Fractional Shares”), as permitted by Delaware law by rounding down the number of Fractional Shares held by each of our shareholders to the nearest whole share and paying each shareholder cash for such Fractional Shares.
Prior to September 8, 2021, the Company entered into additional subscription agreements (the “Subscription Agreements”) with investors providing for the private placement of the Company’s shares. Under the terms of the Subscription Agreements, investors are required to fund drawdowns to purchase the Company’s shares up to the amount of their respective Capital Commitment on an as-needed basis each time the Company delivers a drawdown notice to its investors. As of September 8, 2021, all Capital Commitments in the amount of $3,926.3 million ($80.0 million from affiliates of the Adviser) had been drawn.

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 net asset value per share, the Company will issue shares at the greater of (i) the most recently computed net asset value 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 net asset value per share). For example, if the most recently computed net asset value 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 net asset value 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 net asset value 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.

Share Repurchase Plan

On 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 the Company’s common shares at prices below net asset value 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 put the 10b5-1 Plan in place because it believes that, in the current market conditions, if its common shares are trading below its then-current net asset value per share, it is in the best interest of the Company’s shareholders for the Company to reinvest in its portfolio.

The Company 10b5-1 Plan is intended to allow the Company to repurchase its common shares at times when it otherwise might be prevented from doing so under insider trading laws. The Company 10b5-1 Plan requires Morgan Stanley & Co. LLC, as the Company’s agent, to repurchase common shares on the Company’s behalf when the market price per share is below the most recently reported net asset value per share (including any updates, corrections or adjustments publicly announced by the Company to any previously announced net asset value per share). The most recently reported net asset value per share will also be adjusted on the record date of any special distributions declared. Under the Company 10b5-1 Plan, the agent will increase the volume of purchases made as the price of our common shares declines, subject to volume restrictions. The timing and amount of any share repurchases will depend on the terms and conditions of the Company 10b5-1 Plan, the market price of our common shares and trading volumes, and no assurance can be given that any particular amount of common shares will be repurchased.

The purchase of shares pursuant to the Company 10b5-1 Plan is intended to satisfy the conditions of Rule 10b5-1 and Rule 10b-18 under the Exchange Act, and will otherwise be subject to applicable law, including Regulation M, which may prohibit purchases under certain circumstances.

The Company 10b5-1 Plan commenced on November 26, 2021 and will terminate upon the earliest to occur of (i) 12-months from its commencement (tolled for periods during which the Company 10b5-1 Plan is suspended), (ii) the end of the trading day on which the aggregate purchase price for all shares purchased under the Company 10b5-1 Plan equals approximately $262 million (representing the net proceeds from the IPO) and (iii) the occurrence of certain other events described in the Company 10b5-1 Plan.

The following table summarizes the shares repurchased under the Company 10b5-1 Plan during the nine months ended September 30, 2022 (dollars in thousands except share amounts):

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.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
The information contained in this section should be read in conjunction with “Item 1. Financial Statements.”  This discussion contains forward-looking statements, which relate to future events our future performance or financial condition and involves numerous risks and uncertainties, including, but not limited to, those set forth in “Risk Factors” in Part I, Item 1A of our annual report on Form 10-K for the year ended December 31, 2021 as updated by the Company's periodic filings with the Securities and Exchange Commission.
Overview and Investment Framework
We are a Delaware statutory trust structured as a non-diversified, closed-end management investment company that has elected to be regulated as a BDC under the 1940 Act. In addition, for U.S. federal income tax purposes, we elected to be treated as a RIC under the Code. We are managed by our Adviser. The Administrator will provide the administrative services necessary for us to operate.
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. We do not currently expect to focus on investments in issuers that are distressed or in need of rescue financing.
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.
Key Components of Our Results of Operations
Investments
We focus primarily on loans and securities, including syndicated loans, of private U.S. companies, which includes small and middle market companies. In many market environments, we believe such a focus offers an opportunity for superior risk-adjusted returns.

Our level of investment activity (both the number of investments and the size of each investment) can and will vary substantially from period to period depending on many factors, including the amount of debt and equity capital available to middle market companies, the level of merger and acquisition activity for such companies, the general economic environment, trading prices of loans and other securities and the competitive environment for the types of investments we make.
Revenues
We generate revenues in the form of interest income from the debt securities we hold and dividends. Our debt investments typically have a term of five to eight years and bear interest at floating rates on the basis of a benchmark such as LIBOR, SOFR or SONIA. In some instances, we receive payments on our debt investments based on scheduled amortization of the outstanding balances. In addition, we may receive repayments of some of our debt investments prior to their scheduled maturity date. The frequency or volume of these repayments fluctuates significantly from period to period. Our portfolio activity also reflects the proceeds of sales of securities. In some cases, our investments may provide for deferred interest payments or PIK interest. The principal amount of loans and any accrued but unpaid interest generally become due at the maturity date.
In addition, we generate revenue in the form of commitment, loan origination, structuring or diligence fees, fees for providing managerial assistance to our portfolio companies, and possibly consulting fees.

Expenses
Except as specifically provided below, all investment professionals and staff of the Adviser, when and to the extent engaged in providing investment advisory services to us, and the base compensation, bonus and benefits, and the routine overhead expenses, of such personnel allocable to such services, will be provided and paid for by the Adviser. We bear all other costs and expenses of our operations, administration and transactions, including, but not limited to (a) investment advisory fees, including management fees and incentive fees, to the Adviser, pursuant to the Investment Advisory Agreement; (b) our allocable portion of compensation, 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) our chief compliance officer, chief financial officer and their respective staffs; (ii) investor relations, legal, operations and other non-investment professionals at the Administrator that perform duties for us; and (iii) any internal audit group personnel of Blackstone or any of its affiliates; and (c) all other expenses of our operations, administrations and transactions.
From time to time, the Adviser, the Administrator or their affiliates may pay third-party providers of goods or services on our behalf. We will reimburse the Adviser, Administrator or such affiliates thereof for any such amounts. From time to time, the Adviser or the Administrator may defer or waive fees and/or rights to be reimbursed for expenses. The Administrator has elected to forgo any reimbursement for rent and other occupancy costs for the three and nine months ended September 30, 2022 and 2021. However, the Administrator may seek reimbursement for such costs in future periods. All of the foregoing expenses will ultimately be borne by our shareholders.
Costs and expenses of the Administrator and the Adviser that are eligible for reimbursement by us will be reasonably allocated on the basis of time spent, assets under management, usage rates, proportionate holdings, a combination thereof or other reasonable methods determined by the Administrator in accordance with policies adopted by the Board.
Expense Support and Conditional Reimbursement Agreement
We have entered into an Expense Support Agreement with the Adviser. For additional information see “Item 1. Consolidated Financial Statements—Notes to Consolidated Financial Statements—Note 3. Agreements and Related Party Transactions.”

Average loan-to-value represents the net ratio of loan-to-value for each portfolio company, weighted based on the fair value of total applicable private debt investments. Loan-to-value is calculated as the current total net debt through each respective loan tranche divided by the estimated enterprise value of the portfolio company as of the most recent quarter end.
(4)Weighted average yield for new investment commitments or investments fully sold or paid down, as applicable, on originated loans.
As of September 30, 2022, our portfolio companies had a weighted average annual revenue of $635.0 million and weighted average annual EBITDA of $162.4 million. These calculations include all private debt investments for which fair value is determined by the Board in conjunction with a third-party valuation firm and excludes quoted assets. Amounts are weighted based on fair market value of each respective investment. Amounts were derived from the most recently available portfolio company financial statements, have not been independently estimated by us, and may reflect a normalized or adjusted amount. Accordingly, we make no representation or warranty in respect of this information.

Total investment income increased to $226.8 million for the three months ended September 30, 2022 from $166.9 million for the same period in the prior year primarily driven by increasing interest rates and a stable balance of our investments. The size of our investment portfolio at fair value increased to $9,672.1 million at September 30, 2022 from

$8,223.0 million at September 30, 2021. Additionally, for the three months ended September 30, 2022, we accrued $1.7 million of non-recurring interest income (e.g., prepayment premiums and accelerated accretion of upfront loan origination fees and unamortized discounts) as compared to $16.4 million for the same period in the prior year. For the three months ended September 30, 2022 and 2021, payment-in-kind income represented 4.8% and 0.6% of investment income, respectively. We expect that investment income will vary based on a variety of factors including the pace of our originations and repayments.
Total investment income increased to $599.4 million for the nine months ended September 30, 2022 from $432.7 million for the same period in the prior year primarily driven by a higher weighted average yield on our investments and offset by lower prepayment related income. The size of our investment portfolio at fair value increased to $9,672.1 million at September 30, 2022 from $8,223.0 million at September 30, 2021. Additionally, for the nine months ended September 30, 2022, we accrued $2.0 million of non-recurring interest income (e.g., prepayment premiums and accelerated accretion of upfront loan origination fees and unamortized discounts) as compared to $41.0 million for the same period in the prior year. For the nine months ended September 30, 2022 and 2021, payment-in-kind income represented 5.1% and 0.8% of investment income, respectively. We expect that investment income will vary based on a variety of factors including the pace of our originations and repayments.
As the impact of inflation persists, it could cause operational and/or liquidity issues at our portfolio companies which could restrict their ability to make cash interest payments. Additionally, we may experience full or partial losses on our investments which may ultimately reduce our investment income in future periods. In addition, the rise in interest rates in order to control inflation may correlate to increases or decreases in our net income. Increases in interest rates may adversely affect our existing borrowers.

Interest Expense
Total interest expense (including unused fees and other debt financing expenses), increased to $55.3 million for the three months ended September 30, 2022 from $32.7 million for the same period in the prior year primarily driven by increased borrowings under our credit facilities and rising interest rates. The average principal debt outstanding increased to $5,867.3 million for the three months ended September 30, 2022 from $4,487.3 million for the same period in the prior year, weighted average interest rate increased to 3.67% for the three months ended September 30, 2022 from 2.83% for the same period in the prior year.
Total interest expense (including unused fees and other debt financing expenses), increased to $140.7 million for the nine months ended September 30, 2022 from $81.1 million for the same period in the prior year primarily driven by increased borrowings under our credit facilities, our unsecured bond issuances and rising interest rates. The average principal debt outstanding increased to $5,750.0 million for the nine months ended September 30, 2022 from $3,546.3 million for the same

period in the prior year, partially offset by a decrease in our weighted average interest rate to 3.18% for the nine months ended September 30, 2022 from 2.92% for the same period in the prior year.
Management Fees
Management fees increased to $25.4 million for the three months ended September 30, 2022 from $15.4 million for the same period in the prior year primarily due to an increase in gross assets. The Adviser voluntarily waived management fees following the IPO such that the management fee will remain at 0.75% for a period of two years following the IPO (versus the contractual rate of 1.00%), which resulted in waivers of $6.3 million and $0.0 million for the three months ended September 30, 2022 and 2021, respectively.
Management fees increased to $76.9 million for the nine months ended September 30, 2022 from $40.4 million for the same period in the prior year primarily due to an increase in gross assets. The Adviser voluntarily waived management fees following the IPO such that the management fee will remain at 0.75% for a period of two years following the IPO (versus the contractual rate of 1.00%), which resulted in waivers of $19.2 million and $0.0 million for the nine months ended September 30, 2022 and 2021, respectively.
Our total gross assets increased to $9,925.8 million at September 30, 2022 from $8,821.7 million at September 30, 2021.
Income Based Incentive Fees
Income based incentive fees increased to $26.1 million for the three months ended September 30, 2022 from $17.0 million for the same period in the prior year primarily due to our deployment of capital. The Adviser voluntarily waived incentive fees following the IPO such that the fee will remain at 15.0% for a period of two years following the IPO (versus the contractual rate of 17.5%), which resulted in waivers of $3.7 million and $0.0 million for the three months ended September 30, 2022 and 2021, respectively. Pre-incentive fee net investment income increased to $149.1 million for the three months ended September 30, 2022 from $113.2 million for the same period in the prior year.
Income based incentive fees increased to $68.3 million for the nine months ended September 30, 2022 from $45.1 million for the same period in the prior year primarily due to our deployment of capital. The Adviser voluntarily waived incentive fees following the IPO such that the fee will remain at 15.0% for a period of two years following the IPO (versus the contractual rate of 17.5%), which resulted in waivers of $9.8 million and $0.0 million for the nine months ended September 30, 2022 and 2021, respectively. Pre-incentive fee net investment income increased to $390.0 million for the nine months ended September 30, 2022 from $300.9 million for the same period in the prior year.
Capital Gains Based Incentive Fees
We accrued capital gains incentive fees of $(5.4) million for the three months ended September 30, 2022 compared to $2.4 million for the same period in the prior year, primarily due to net realized and unrealized losses for the three months ended September 30, 2022 as compared to net realized and unrealized gains for the same period in the prior year.
We accrued capital gains incentive fees of $(8.6) million for the nine months ended September 30, 2022 compared to $14.6 million for the same period in the prior year, primarily due to net realized and unrealized losses for the nine months ended September 30, 2022 as compared to net realized and unrealized gains for the same period in the prior year.
The accrual for any capital gains incentive fee under U.S. GAAP in a given period may result in an additional expense if such cumulative amount is greater than in the prior period or a reduction of previously recorded expense if such cumulative amount is less in the prior period. If such cumulative amount is negative, then there is no accrual.
Other Expenses
Professional fees include legal, rating agencies, audit, tax, valuation, technology and other professional fees incurred related to the management of us. Administrative service expenses represent fees paid to the Administrator for our allocable portion of overhead and other expenses incurred by the Administrator in performing its obligations under the administration agreement, including our allocable portion of the cost of certain of our executive officers, their respective staff and other non-investment professionals that perform duties for us. Prior to the IPO, offering costs included costs associated with our private offering. Other general and administrative expenses include insurance, filing, research, our sub-administrator, subscriptions and other costs.

Total other expenses remained flat, amounting to $3.3 million for the three months ended September 30, 2022 and $3.3 million for the same period in the prior year primarily driven by our administrative service expenses.
Total other expenses increased to $9.6 million for the nine months ended September 30, 2022 from $8.4 million for the same period in the prior year primarily driven by an increase in our administrative service expenses which was attributable to growth in the investment portfolio.
The Adviser may elect to make Expense Payments on our behalf, subject to future Reimbursement Payments pursuant to the Expense Support Agreement described above in “—Key Components of Our Results of Operations—Expenses.”
Income Taxes, Including Excise Taxes
We elected to be treated as a RIC under Subchapter M of the Code, and we intend to operate in a manner so as to continue to qualify for the tax treatment applicable to RICs. To qualify for tax treatment as a RIC, we must, among other things, distribute to our shareholders in each taxable year generally at least 90% of the sum of our investment company taxable income, as defined by the Code (without regard to the deduction for dividends paid), and net tax-exempt income for that taxable year. To maintain our tax treatment as a RIC, we, among other things, intend to make the requisite distributions to our shareholders, which generally relieve us from corporate-level U.S. federal income taxes.
Depending on the level of taxable income earned in a tax year, we may carry forward taxable income (including net capital gains, if any) in excess of current year dividend distributions from the current tax year into the next tax year and pay a nondeductible 4% U.S. federal excise tax on such taxable income, as required. To the extent that we determine that our estimated current year annual taxable income will be in excess of estimated current year dividend distributions from such income, we will accrue excise tax on estimated excess taxable income.
For the three and nine months ended September 30, 2022, we incurred $0.0 million and $1.4 million, respectively, of U.S. federal excise tax. For the three and nine months ended September 30, 2021 we incurred $2.2 million and $1.9 million, respectively, of U.S. federal excise tax.
Net Unrealized Gain (Loss)
Net unrealized gain (loss) was comprised of the following (dollar amounts in thousands):

Net unrealized gain (loss)$(70,586)$18,033 $(99,975)$92,028 

For the three months ended September 30, 2022, the net unrealized loss was primarily driven by an decrease in the fair value of our debt investments during the period. The fair value of our debt investments as a percentage of principal decreased by 0.5% as compared to a 0.3% increase in fair value of our debt investments for the same period in prior year driven in part by rising rates and inflation during the three months ended September 30, 2022.

For the nine months ended September 30, 2022, the net unrealized loss was primarily driven by an decrease in the fair value of our debt investments during the period. The fair value of our debt investments as a percentage of principal decreased by 0.2% as compared to a 1.3% increase in fair value of our debt investments for the same period in prior year driven in part by rising rates and inflation during the nine months ended September 30, 2022.

Net realized gain (loss)$34,388 $(1,833)$42,639 $5,308 
For the three and nine months ended September 30, 2022, we generated realized gains of $36.2 million and $44.8 million, respectively, partially offset by realized losses of $5.0 million and $5.7 million respectively, primarily from full or partial sales of our debt investments.
For the three and nine months ended September 30, 2021, we generated realized gains of $7.0 million and $15.5 million, respectively, partially offset by realized losses of $8.8 million and $9.0 million respectively, primarily from full or partial sales of our debt investments.
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 September 30, 2022 and December 31, 2021, we had four revolving credit facilities outstanding and we had five issuances of 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 September 30, 2022 and December 31, 2021, we had an aggregate amount of $5,550.6 million and $5,544.3 million of senior securities outstanding and our asset coverage ratio was 175.1% and 180.2%, 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 September 30, 2022, taken together with our $999.4 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 $84.0 million of Level 2 debt investments as of September 30, 2022, which could provide additional liquidity if necessary. A continued disruption in the financial markets caused by recent macroeconomic or market volatility, COVID-19 or any other negative economic development 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 recently obtained. These factors may limit our ability to make new investments and adversely impact our results of operations.
As of September 30, 2022, we had $131.2 million in cash and cash equivalents. During the nine months ended September 30, 2022, cash provided by operating activities was $505.1 million, primarily as a result of proceeds from sale of investments funding portfolio investments of $955.6 million; partially offset by purchases of investments of $808.8 million. Cash used in financing activities was $476.8 million during the period, which was primarily as a result of dividends paid in cash of $305.8 million and repurchase of shares of $215.6 million.
As of September 30, 2021, we had $259.6 million in cash and cash equivalents. During the nine months ended September 30, 2021, cash used in operating activities was $2,440.0 million, primarily as a result of funding portfolio

investments of $4,438.5 million; partially offset by proceeds from sale of investments of $1945.6 million. Cash provided by financing activities was $2,481.0 million during the period, which was primarily as a result of net borrowings on our credit facilities and our unsecured debt issuances of $1,959.4 million; our proceeds from issuance of common shares of $716.7 million; and partially offset by dividends paid in cash of $189.7 million.
Equity
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.
In connection with the listing of the Company’s common shares on the NYSE, the Board decided to eliminate any outstanding fractional common shares (the “Fractional Shares”), as permitted by Delaware law by rounding down the number of Fractional Shares held by each of our shareholders to the nearest whole share and paying each shareholder cash for such Fractional Shares.

With respect to distributions, we have adopted an “opt out” dividend reinvestment plan for shareholders. As a result, in the event of a declared cash distribution or other distribution, each shareholder that has not “opted out” of the dividend reinvestment plan will have their dividends or distributions automatically reinvested in additional shares rather than receiving cash distributions. Shareholders who receive distributions in the form of shares will be subject to the same U.S. federal, state and local tax consequences as if they received cash distributions. Refer to “Item 1. Consolidated Financial Statements—Notes to Consolidated Financial Statements—Note 8. Net Assets” to the consolidated financial statements for more information on our dividend reinvestment program.

Share Repurchase Plan
On 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 the Company’s common shares at prices below net asset value 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 put the 10b5-1 Plan in place because it believes that, in the current market conditions, if its common shares are trading below its then-current net asset value per share, it is in the best interest of the Company’s shareholders for the Company to reinvest in its portfolio.

Off-Balance Sheet Arrangements
Portfolio Company Commitments
Our investment portfolio contains and is expected to continue to contain debt investments which are in the form of lines of credit or delayed draw commitments, which require us to provide funding when requested by portfolio companies in accordance with underlying loan agreements. As of September 30, 2022 and December 31, 2021, we had unfunded delayed draw term loans and revolvers with an aggregate principal amount of $849.0 million and $1,407.3 million, respectively.
Other Commitments and Contingencies
From time to time, we may become a party to certain legal proceedings incidental to the normal course of its business. At September 30, 2022, management is not aware of any pending or threatened litigation.

Related-Party Transactions
We have entered into a number of business relationships with affiliated or related parties, including the following:
the Investment Advisory Agreement;
the Administration Agreement; and
Expense Support and Conditional Reimbursement Agreement.
In addition to the aforementioned agreements, we, our Adviser and certain of our Adviser’s affiliates have been granted exemptive relief by the SEC to co-invest with other funds managed by our Adviser or its affiliates in a manner consistent with our investment objectives, positions, policies, strategies and restrictions as well as regulatory requirements and other pertinent factors. See “Item 1. Consolidated Financial Statements—Notes to Consolidated Financial Statements—Note 3. Agreements and Related Party Transactions.
Recent Developments
Macroeconomic Environment
The U.S. Federal Reserve’s recent actions to increase interest rates in order to control inflation have created further uncertainty for the economy and for our borrowers. Although our business model is such that rising interest rates will, all else being equal, correlate to increases in our net income, increases in interest rates may adversely affect our existing borrowers. It is difficult to predict the full impact of recent changes and any future changes in interest rates or inflation.
Reference Rate Reform
LIBOR and certain other floating rate benchmark indices to which our floating rate loans and other loan agreements are tied, including, without limitation, the Euro Interbank Offered Rate, or EURIBOR, the Stockholm Interbank Offered Rate, or STIBOR, the Australian Bank Bill Swap Reference Rate, or BBSY, the Canadian Dollar Offered Rate, or CDOR, the Swiss Average Rate Overnight, or SARON, and the Copenhagen Interbank Offering Rate, or CIBOR, or collectively, IBORs, are the subject of recent national, international and regulatory guidance and proposals for reform. As of December 31, 2021, the ICE Benchmark Association, or IBA, ceased publication of all non-USD LIBOR and the one-week and two-month USD LIBOR and, as and previously announced, intends to cease publication of remaining U.S. dollar LIBOR settings immediately after June 30, 2023. Further, on March 15, 2022, the Consolidated Appropriations Act of 2022, which includes the Adjustable Interest Rate (LIBOR) Act, was signed into law in the U.S. This legislation establishes a uniform benchmark replacement process for financial contracts maturing after June 30, 2023 that do not contain clearly defined or practicable fallback provisions. The legislation also creates a safe harbor that shields lenders from litigation if they choose to utilize a replacement rate recommended by the Board of Governors of the Federal Reserve.
The U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, a steering committee composed of large U.S. financial institutions, has identified the Secured Overnight Financing Rate, or SOFR, a new index calculated using short-term repurchase agreements backed by U.S. Treasury securities, as its preferred alternative rate for USD LIBOR. Additionally, market participants have started to transition from GBP LIBOR to the Sterling Overnight Index Average, or SONIA, in line with guidance from the U.K. regulators.

At this time, it is not possible to predict how markets will respond to SOFR, SONIA, or other alternative reference rates as the transition away from USD LIBOR and GBP LIBOR proceeds. Despite the LIBOR transition in other markets, benchmark rate methodologies in Europe, Australia, Canada, Switzerland, and Denmark have been reformed and rates such as EURIBOR, STIBOR, BBSY, CDOR, SARON, and CIBOR may persist as International Organization of Securities Commissions, or IOSCO, compliant reference rates moving forward. However, multi-rate environments may persist in these markets as regulators and working groups have suggested market participants adopt alternative reference rates.
Critical Accounting Estimates
The preparation of the consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Changes in the economic environment, financial markets, and any other parameters used in determining such estimates could cause actual results to differ. Our critical accounting estimates, including those relating to the valuation of our investment portfolio, are described in our Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on February 28, 2022, and elsewhere in our filings with the SEC. There have been no material changes in our critical accounting policies and practices.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.
Valuation Risk
We have invested, and plan to continue to invest, primarily in illiquid debt and equity securities of private companies. Most of our investments will not have a readily available market price, and we value these investments at fair value as determined in good faith by the Board, based on, among other things, the input of the Adviser, our Audit Committee and independent third-party valuation firms engaged at the direction of the Board, and in accordance with our valuation policy. There is no single standard for determining fair value. As a result, determining fair value requires that judgment be applied to the specific facts and circumstances of each portfolio investment while employing a consistently applied valuation process for the types of investments we make. If we were required to liquidate a portfolio investment in a forced or liquidation sale, we may realize amounts that are different from the amounts presented and such differences could be material.
Interest Rate Risk

Interest rate sensitivity refers to the change in earnings that may result from changes in the level of interest rates. We intend to fund portions of our investments with borrowings, and at such time, our net investment income will be affected by the difference between the rate at which we invest and the rate at which we borrow. Accordingly, we cannot assure shareholders that a significant change in market interest rates will not have a material adverse effect on our net investment income. As of the date of this report, the U.S. Federal Reserve raised the federal funds target range to 3.00-3.25% in the third quarter of 2022 and further to 3.75-4.00% in November, 2022.
As of September 30, 2022, 99.9% of our debt investments at fair value were at floating rates. Based on our Consolidated Statements of Assets and Liabilities as of September 30, 2022, the following table shows the annualized impact on net income of hypothetical base rate changes in interest rates (considering base rate floors and ceilings for floating rate instruments assuming no changes in our investment and borrowing structure) (dollar amounts in thousands):

Inflation Risk
In the U.S., rising interest rates and the resulting higher cost of capital has the potential to negatively impact the free cash flow and credit quality of certain borrowers. In addition, rising costs resulting from heightened energy prices and input costs are contributing to margin pressures at certain of our portfolio companies. Such investments would continue to be negatively impacted by a sustained high rate of inflation if they are unable to mitigate margin pressures, especially if concurrent with an increase in their debt service costs. If higher than expected rates of inflation and expected significant interest rate increases in 2022 occur concurrently with a period of economic weakness or a slowdown in growth, portfolio performance in our portfolio companies may be negatively impacted. Although rising interest rates have the potential to negatively impact the financial performance of certain borrowers, the performance of the Company has generally benefited from rising interest rates as a substantial majority of the portfolio is floating rate. In addition, continued market dislocation may create attractive deployment opportunities, as borrowers seek alternative lending sources. Nonetheless, significant market dislocation could limit the liquidity of certain assets traded in the credit markets, and this would impact the Company's ability to sell such assets at attractive prices or in a timely manner.
Inflation persisted at multi-decade highs in many major economies around the world, prompting central banks to pursue monetary policy tightening actions that are likely to continue to create headwinds to economic growth. In the U.S., annual inflation was 8.2% in September, down from 9.1% in June but still well above the Federal Reserve’s long-run target of 2%. In Eurozone economies, inflation increased to a record 9.9% in September, up from 9.1% in August.
