NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
SEPTEMBER 30, 2023
(DOLLAR AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA AND AS OTHERWISE INDICATED)
(UNAUDITED)
NOTE 1. ORGANIZATION
Gladstone Investment Corporation (“Gladstone Investment”) was incorporated under the General Corporation Law of the State of Delaware on February 18, 2005, and completed an initial public offering on June 22, 2005. The terms “the Company,” “we,” “our” and “us” all refer to Gladstone Investment and its consolidated subsidiaries. We are an externally advised, closed-end, non-diversified management investment company that has elected to be treated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (the “1940 Act”), and are applying the guidance of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, “Financial Services-Investment Companies” (“ASC 946”). In addition, we have elected to be treated for U.S. federal income tax purposes as a regulated investment company (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”). We were established for the purpose of investing in debt and equity securities of established private businesses in the United States (“U.S.”). Debt investments primarily take the form of two types of loans: secured first lien loans and secured second lien loans. Equity investments primarily take the form of preferred or common equity (or warrants or options to acquire the foregoing), often in connection with buyouts and other recapitalizations. Our investment objectives are to: (i) achieve and grow current income by investing in debt securities of established businesses that we believe will provide stable earnings and cash flow to pay expenses, make principal and interest payments on our outstanding indebtedness and make distributions to stockholders that grow over time, and (ii) provide our stockholders with long-term capital appreciation in the value of our assets by investing in equity securities of established businesses, generally in combination with the aforementioned debt securities, that we believe can grow over time to permit us to sell our equity investments for capital gains. We intend that our investment portfolio over time will consist of approximately 75.0% in debt investments and 25.0% in equity investments, at cost. As of September 30, 2023, our investment portfolio was comprised of 78.0% in debt investments and 22.0% in equity investments, at cost.
Gladstone Business Investment, LLC (“Business Investment”), a wholly-owned subsidiary of ours, was established on August 11, 2006 for the sole purpose of holding certain investments pledged as collateral under our line of credit. The financial statements of Business Investment are consolidated with those of Gladstone Investment.
We are externally managed by Gladstone Management Corporation (the “Adviser”), an affiliate of ours and a U.S. Securities and Exchange Commission (“SEC”) registered investment adviser, pursuant to an investment advisory and management agreement (the “Advisory Agreement”). Administrative services are provided by Gladstone Administration, LLC (the “Administrator”), an affiliate of ours and the Adviser, pursuant to an administration agreement (the “Administration Agreement”). Refer to Note 4 — Related Party Transactions for more information regarding these arrangements.
NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Unaudited Interim Financial Statements and Basis of Presentation
We prepare our interim financial statements in accordance with accounting principles generally accepted in the U.S. (“GAAP”) for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Articles 6, 10 and 12 of SEC Regulation S-X. Accordingly, we have not included in this quarterly report all of the information and notes required by GAAP for annual financial statements. The accompanying Consolidated Financial Statements include our accounts and those of our wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated. In accordance with Article 6 of Regulation S-X, we do not consolidate portfolio company investments. Under the investment company rules and regulations pursuant to the American Institute of Certified Public Accountants Audit and Accounting Guide for Investment Companies, codified in ASC 946, we are precluded from consolidating any entity other than another investment company, except that ASC 946 provides for the consolidation of a controlled operating company that provides substantially all of its services to the investment company or its consolidated subsidiaries. In our opinion, all adjustments, consisting solely of normal recurring accruals, necessary for the fair statement of financial statements for the interim periods have been included. The results of operations for the three and six months ended September 30, 2023 are not necessarily indicative of results that ultimately may be achieved for the fiscal year ending March 31, 2024 or any future interim period. The interim financial statements and notes thereto should be read in conjunction with the financial
17

Table of Contents
statements and notes thereto included in our annual report on Form 10-K for the fiscal year ended March 31, 2023, as filed with the SEC on May 10, 2023.
Use of Estimates
Preparing financial statements requires management to make estimates and assumptions that affect the amounts reported in our accompanying Consolidated Financial Statements and these Notes to Consolidated Financial Statements. Actual results may differ from those estimates.
Investment Valuation Policy
Accounting Recognition
We record our investments at fair value in accordance with the FASB ASC Topic 820, “Fair Value Measurements and Disclosures” (“ASC 820”) and the 1940 Act. Investment transactions are recorded on the trade date. Realized gains or losses are generally measured by the difference between the net proceeds from the repayment or sale and the cost basis of the investment, without regard to unrealized appreciation or depreciation previously recognized, and include investments charged off during the period, net of recoveries. Unrealized appreciation or depreciation primarily reflects the change in investment fair values, including the reversal of previously recorded unrealized appreciation or depreciation when gains or losses are realized.
Board Responsibility
Our board of directors (the “Board of Directors”) has approved investment valuation policies and procedures pursuant to Rule 2a-5 (the “Policy”) and, in July 2022, designated the Adviser to serve as the Board of Directors’ valuation designee ("Valuation Designee") under the 1940 Act.
In accordance with the 1940 Act, our Board of Directors has the ultimate responsibility for reviewing the good faith fair value determination of our investments for which market quotations are not readily available based on our Policy and for overseeing the Valuation Designee. Such review and oversight includes receiving written fair value determinations and supporting materials provided by the Valuation Designee, in coordination with the Administrator and with the oversight by the Company's chief valuation officer (collectively, the “Valuation Team”). The Valuation Committee of our Board of Directors (comprised entirely of independent directors) meets to review the valuation determinations and supporting materials, discusses the information provided by the Valuation Team, determines whether the Valuation Team has followed the Policy, and reviews other facts and circumstances, including current valuation risks, conflicts of interest, material valuation matters, appropriateness of valuation methodologies, back-testing results, price challenges/overrides, and ongoing monitoring and oversight of pricing services. After the Valuation Committee concludes its meeting, it and the chief valuation officer, representing the Valuation Designee, present the Valuation Committee’s findings on the Valuation Designee's determinations to the entire Board of Directors so that the full Board of Directors may review the Valuation Designee's determined fair values of such investments in accordance with the Policy.
There is no single standard for determining fair value (especially for privately-held businesses), as fair value depends upon the specific facts and circumstances of each individual investment. In determining the fair value of our investments, the Valuation Team, led by the chief valuation officer, uses the Policy, and each quarter the Valuation Committee and Board of Directors review the Policy to determine if changes thereto are advisable and whether the Valuation Team has applied the Policy consistently.
Use of Third-Party Valuation Firms
The Valuation Team engages third-party valuation firms to provide independent assessments of fair value of certain of our investments.
A third-party valuation firm generally provides estimates of fair value on our debt investments. The Valuation Team generally assigns the third-party valuation firm’s estimates of fair value to our debt investments where we do not have the ability to effectuate a sale of the applicable portfolio company. The Valuation Team corroborates this third-party valuation firm’s estimates of fair value using one or more of the valuation techniques discussed below. The Valuation Team’s estimate of value on a specific debt investment may significantly differ from the third-party valuation firm’s. When this occurs, our Valuation Committee and Board of Directors review whether the Valuation Team has followed the Policy and
18

Table of Contents
the Valuation Committee reviews whether the Valuation Designee’s determined fair value is reasonable in light of the Policy and other relevant facts and circumstances.
We may engage other independent valuation firms to provide earnings multiple ranges, as well as other information, and evaluate such information for incorporation into the total enterprise value (“TEV”) of certain of our investments. Generally, at least once per year, we engage an independent valuation firm to value or review the valuation of each of our significant equity investments, which includes providing the information noted above. The Valuation Team evaluates such information for incorporation into our TEV, including review of all inputs provided by the independent valuation firm. The Valuation Team then presents a determination to our Valuation Committee as to the fair value. Our Valuation Committee reviews the determined fair value and whether it is reasonable in light of the Policy and other relevant facts and circumstances.
Valuation Techniques
In accordance with ASC 820, the Valuation Team uses the following techniques when valuing our investment portfolio:
•Total Enterprise Value — In determining the fair value using a TEV, the Valuation Team first calculates the TEV of the portfolio company by incorporating some or all of the following factors: the portfolio company’s ability to make payments and other specific portfolio company attributes; the earnings of the portfolio company (the trailing or projected twelve month revenue or earnings before interest, taxes, depreciation and amortization (“EBITDA”)); EBITDA multiples obtained from our indexing methodology whereby the original transaction EBITDA multiple at the time of our closing is indexed to a general subset of comparable disclosed transactions and EBITDA multiples from recent sales to third parties of similar securities in similar industries; a comparison to publicly traded securities in similar industries; and other pertinent factors. The Valuation Team generally reviews industry statistics and may use outside experts when gathering this information. Once the TEV is determined for a portfolio company, the Valuation Team generally allocates the TEV to the portfolio company’s securities based on the facts and circumstances of the securities, which typically results in the allocation of fair value to securities based on the order of their relative priority in the capital structure. Generally, the Valuation Team uses TEV to value our equity investments and, in the circumstances where we have the ability to effectuate a sale of a portfolio company, our debt investments.
TEV is primarily calculated using EBITDA and EBITDA multiples; however, TEV may also be calculated using revenue and revenue multiples or a discounted cash flow (“DCF”) analysis whereby future expected cash flows of the portfolio company are discounted to determine a net present value using estimated risk-adjusted discount rates, which incorporate adjustments for nonperformance and liquidity risks.
•Yield Analysis — The Valuation Team generally determines the fair value of our debt investments for which we do not have the ability to effectuate a sale of the applicable portfolio company using the yield analysis, which includes a DCF calculation and assumptions that the Valuation Team believes market participants would use, including: estimated remaining life, current market yield, current leverage, and interest rate spreads. This technique develops a modified discount rate that incorporates risk premiums including, among other things, increased probability of default, increased loss upon default, and increased liquidity risk. Generally, the Valuation Team uses the yield analysis to corroborate both estimates of value provided by a third-party valuation firm and market quotes.
•Market Quotes — For our investments for which a limited market exists, we generally base fair value on readily available and reliable market quotations, which are corroborated by the Valuation Team (generally by using the yield analysis described above). In addition, the Valuation Team assesses trading activity for similar investments and evaluates variances in quotations and other market insights to determine if any available quoted prices are reliable. Typically, the Valuation Team uses the lower indicative bid price in the bid-to-ask price range obtained from the respective originating syndication agent’s trading desk on or near the valuation date. The Valuation Team may take further steps to consider additional information to validate that price in accordance with the Policy. For securities that are publicly traded, we generally base fair value on the closing market price of the securities we hold as of the reporting date. For restricted securities that are publicly traded, we generally base fair value on the closing market price of the securities we hold as of the reporting date less a discount for the restriction, which includes consideration of the nature and term to expiration of the restriction and the lack of marketability of the security.
19

Table of Contents
•Investments in Funds — For equity investments in other funds for which we cannot effectuate a sale of the fund, the Valuation Team generally determines the fair value of our invested capital at the net asset value (“NAV”) provided by the fund. Any invested capital that is not yet reflected in the NAV provided by the fund is valued at par value. The Valuation Team may also determine fair value of our investments in other investment funds based on the capital accounts of the underlying entity.
In addition to the valuation techniques listed above, the Valuation Team may also consider other factors when determining the fair value of our investments, including: the nature and realizable value of the collateral, including external parties’ guaranties, any relevant offers or letters of intent to acquire the portfolio company, timing of expected loan repayments, and the markets in which the portfolio company operates.
Fair value measurements of our investments may involve subjective judgments and estimates and, due to the uncertainty inherent in valuing these securities, the determinations of fair value may fluctuate from period to period and may differ materially from the values that could be obtained if a ready market for these securities existed. Our NAV could be materially affected if the determinations regarding the fair value of our investments are materially different from the values that we ultimately realize upon our disposal of such securities. Additionally, changes in the market environment and other events that may occur over the life of the investment may cause the gains or losses ultimately realized on these investments to be different than the valuations currently assigned. Further, such investments are generally subject to legal and other restrictions on resale or otherwise are less liquid than publicly traded securities. If we were required to liquidate a portfolio investment in a forced or liquidation sale, we could realize significantly less than the value at which it is recorded.
Refer to Note 3 — Investments for additional information regarding fair value measurements and our application of ASC 820.
Revenue Recognition
Interest Income Recognition
Interest income, adjusted for amortization of premiums, amendment fees and acquisition costs and the accretion of discounts, is recorded on the accrual basis to the extent that such amounts are expected to be collected. Generally, when a loan becomes 90 days or more past due, or if our qualitative assessment indicates that the debtor is unable to service its debt or other obligations, we will place the loan on non-accrual status and cease recognizing interest income on that loan until the borrower has demonstrated the ability and intent to pay contractual amounts due. However, we remain contractually entitled to this interest. Interest payments received on non-accrual loans may be recognized as income or applied to the cost basis, depending upon management’s judgment. Generally, non-accrual loans are restored to accrual status when past-due principal and interest are paid and, in management’s judgment, are likely to remain current, or, due to a restructuring, the interest income is deemed to be collectible. As of September 30, 2023, our loans to Edge Adhesives Holdings, Inc. ("Edge"), J.R. Hobbs Co. – Atlanta, LLC (“J.R. Hobbs”) and The Mountain Corporation (“The Mountain”) were on non-accrual status, with an aggregate debt cost basis of $66.9 million, or 10.3% of the cost basis of all debt investments in our portfolio, and an aggregate fair value of $31.0 million, or 5.1% of the fair value of all debt investments in our portfolio. As of March 31, 2023, our loans to Edge, J.R. Hobbs, and The Mountain were on non-accrual status, with an aggregate debt cost basis of $66.9 million, or 12.0% of the cost basis of all debt investments in our portfolio, and an aggregate fair value of $31.7 million, or 6.2% of the fair value of all debt investments in our portfolio.
Paid-in-kind (“PIK”) interest, computed at the contractual rate specified in the loan agreement, is added to the principal balance of the loan and recorded as interest income. As of September 30, 2023 and March 31, 2023, we did not have any loans with a PIK interest component.
Success Fee Income Recognition
We record success fees as income when earned, which often occurs upon receipt of cash. Success fees are generally contractually due upon a change of control in a portfolio company, typically resulting from an exit or sale, and are non-recurring.
Dividend Income Recognition

Recent Accounting Pronouncements
In June 2022, the FASB issued Accounting Standards Update 2022-03, “Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions” (“ASU 2022-03”), which clarifies the measurement and presentation of fair value for equity securities subject to contractual restrictions that prohibit the sale of the equity security. ASU 2022-03 is effective for annual reporting periods beginning after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted. Our early adoption of ASU 2022-03 did not have a material impact on our financial position, results of operations or cash flows.
NOTE 3. INVESTMENTS
Fair Value
In accordance with ASC 820, we determine the fair value of our investments to be the price that would be received for an investment in a current sale, which assumes an orderly transaction between willing market participants on the measurement date. This fair value definition focuses on exit price in the principal, or most advantageous, market and prioritizes, within a measurement of fair value, the use of market-based inputs over entity-specific inputs. ASC 820 also establishes the following three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of a financial instrument as of the measurement date.
•Level 1 — inputs to the valuation methodology are quoted prices (unadjusted) for identical financial instruments in active markets;
•Level 2 — inputs to the valuation methodology include quoted prices for similar financial instruments in active or inactive markets, and inputs that are observable for the financial instrument, either directly or indirectly, for substantially the full term of the financial instrument. Level 2 inputs are those in markets for which there are few transactions, the prices are not current, little public information exists, or instances where prices vary substantially over time or among brokered market makers; and
•Level 3 — inputs to the valuation methodology are unobservable and significant to the fair value measurement. Unobservable inputs are those inputs that reflect assumptions that market participants would use when pricing the financial instrument and can include the Valuation Team’s assumptions based upon the best available information.
When a determination is made to classify our investments within Level 3 of the valuation hierarchy, such determination is based upon the significance of the unobservable factors to the overall fair value measurement. However, Level 3 financial instruments typically include, in addition to the unobservable, or Level 3, inputs, observable inputs (or components that are actively quoted and can be validated to external sources). The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement.
As of September 30, 2023 and March 31, 2023, all of our investments were valued using Level 3 inputs within the ASC 820 fair value hierarchy, except for our investment in Funko Acquisition Holdings, LLC (“Funko”), which was valued using Level 2 inputs.

Table of Contents
We transfer investments in and out of Level 1, 2 and 3 of the valuation hierarchy as of the beginning balance sheet date, based on changes in the use of observable and unobservable inputs utilized to perform the valuation for the period. There were no transfers in or out of Level 1, 2 and 3 during the six months ended September 30, 2023 and 2022, respectively.
As of September 30, 2023 and March 31, 2023, our investments, by security type, at fair value were categorized as follows within the ASC 820 fair value hierarchy:

Receivables from Portfolio Companies
Receivables from portfolio companies represent non-recurring costs that we incurred on behalf of portfolio companies. Such receivables, net of any allowance for uncollectible receivables, are included in Other assets, net on our accompanying Consolidated Statements of Assets and Liabilities. We generally maintain an allowance for uncollectible receivables from portfolio companies when the receivable balance becomes 90 days or more past due or if it is determined, based upon management’s judgment, that the portfolio company is unable to pay its obligations. We write off accounts receivable when we have exhausted collection efforts and have deemed the receivables uncollectible. As of September 30, 2023 and March 31, 2023, we had gross receivables from portfolio companies of $2.3 million and $2.2 million, respectively. As of both September 30, 2023 and March 31, 2023, the allowance for uncollectible receivables was $1.5 million and $1.6 million, respectively.
NOTE 4. RELATED PARTY TRANSACTIONS
Transactions with the Adviser
We pay the Adviser certain fees as compensation for its services under the Advisory Agreement, consisting of a base management fee and an incentive fee and a loan servicing fee for the Adviser’s role as servicer pursuant to the Credit Facility, all as described below. On July 11, 2023, our Board of Directors, including a majority of the directors who are not parties to the Advisory Agreement or interested persons of either party, approved the annual renewal of the Advisory Agreement through August 31, 2024.

(A)Average total assets subject to the base management fee is defined in the Advisory Agreement as total assets, including investments made with proceeds of borrowings, less any uninvested cash or cash equivalents resulting from borrowings, valued at the end of the applicable quarters within the respective periods and adjusted appropriately for any share issuances or repurchases during the periods.
(B)Reflected as a line item on our accompanying Consolidated Statements of Operations.
(C)The capital gains-based incentive fees are recorded in accordance with GAAP and do not necessarily reflect amounts contractually due under the terms of the Advisory Agreement.
Base Management Fee
The base management fee is payable quarterly to the Adviser pursuant to our Advisory Agreement and is assessed at an annual rate of 2.0%, computed on the basis of the value of our average gross assets at the end of the two most recently completed quarters (inclusive of the current quarter), which are total assets, including investments made with proceeds of borrowings, less any uninvested cash or cash equivalents resulting from borrowings, valued at the end of the applicable quarters within the respective period and adjusted appropriately for any share issuances or repurchases during the period.
Additionally, pursuant to the requirements of the 1940 Act, the Adviser makes available significant managerial assistance to our portfolio companies. The Adviser may also provide other services to our portfolio companies under certain agreements and may receive fees for services other than managerial assistance. Such services may include: (i) assistance obtaining, sourcing or structuring credit facilities, long term loans or additional equity from unaffiliated third parties; (ii) negotiating important contractual financial relationships; (iii) consulting services regarding restructuring of the portfolio company and financial modeling as it relates to raising additional debt and equity capital from unaffiliated third parties; and (iv) taking a primary role in interviewing, vetting and negotiating employment contracts with candidates in connection with adding and retaining key portfolio company management team members. The Adviser non-contractually, unconditionally, and irrevocably credits 100% of any fees received for such services against the base management fee that we would otherwise be required to pay to the Adviser; however, pursuant to the terms of the Advisory Agreement, a small percentage of certain of such fees was retained by the Adviser in the form of reimbursement, at cost, for tasks completed by personnel of the Adviser, primarily related to the valuation of portfolio companies. For the three months ended September 30, 2023 and 2022, these credits totaled $83 thousand and $70 thousand, respectively. For the six months ended September 30, 2023 and 2022, these credits totaled $158 thousand and $106 thousand, respectively.

Table of Contents
Loan Servicing Fee
The Adviser also services the loans held by our wholly-owned subsidiary, Business Investment (the borrower under the Credit Facility), in return for which the Adviser receives a 2.0% annual fee based on the monthly aggregate outstanding balance of loans pledged under the Credit Facility. Since Business Investment is a consolidated subsidiary of ours, coupled with the fact that the total base management fee paid to the Adviser pursuant to the Advisory Agreement cannot exceed 2.0% of total assets (less any uninvested cash or cash equivalents resulting from borrowings) during any given calendar year, we treat payment of the loan servicing fee pursuant to the Credit Facility as a pre-payment of the base management fee under the Advisory Agreement. Accordingly, these loan servicing fees are 100% non-contractually, unconditionally, and irrevocably credited back to us by the Adviser.
Incentive Fee
The incentive fee payable to the Adviser under our Advisory Agreement consists of two parts: an income-based incentive fee and a capital gains-based incentive fee.
The income-based incentive fee rewards the Adviser if our quarterly net investment income (before giving effect to any incentive fee) exceeds 1.75% of our net assets, which we define as total assets less indebtedness and before taking into account any incentive fees payable or contractually due but not payable during the period, at the end of the immediately preceding calendar quarter, adjusted appropriately for any share issuances or repurchases during the period (the “Hurdle Rate”). The income-based incentive fee with respect to our pre-incentive fee net investment income is payable quarterly to the Adviser and is computed as follows:
•No incentive fee in any calendar quarter in which our pre-incentive fee net investment income does not exceed the Hurdle Rate;
•100.0% of our pre-incentive fee net investment income with respect to that portion of such pre-incentive fee net investment income, if any, that exceeds the Hurdle Rate but is less than 2.1875% of our net assets, adjusted appropriately for any share issuances or repurchases during the period, in any calendar quarter; and
•20.0% of the amount of our pre-incentive fee net investment income, if any, that exceeds 2.1875% of our net assets, adjusted appropriately for any share issuances or repurchases during the period, in any calendar quarter.
The second part of the incentive fee is a capital gains-based incentive fee that is determined and payable in arrears as of the end of each fiscal year (or upon termination of the Advisory Agreement, as of the termination date), and equals 20.0% of our realized capital gains, less any realized capital losses and unrealized depreciation, calculated as of the end of the preceding calendar year. The capital gains-based incentive fee payable to the Adviser is calculated based on (i) cumulative aggregate realized capital gains since our inception, less (ii) cumulative aggregate realized capital losses since our inception, less (iii) the entire portfolio’s aggregate unrealized capital depreciation, if any, as of the date of the calculation. If this number is positive at the applicable calculation date, then the capital gains-based incentive fee for such year equals 20.0% of such amount, less the aggregate amount of any capital gains-based incentive fees paid in respect of our portfolio in all prior years. For calculation purposes, cumulative aggregate realized capital gains, if any, equals the sum of the excess between the net sales price of each investment, when sold, and the original cost of such investment since our inception. Cumulative aggregate realized capital losses equals the sum of the deficit between the net sales price of each investment, when sold, and the original cost of such investment since our inception. The entire portfolio’s aggregate unrealized capital depreciation, if any, equals the sum of the deficit between the fair value of each investment security as of the applicable calculation date and the original cost of such investment security. As of and for the six months ended September 30, 2023, no capital gains-based incentive fees were contractually due to the Adviser. During the year ended March 31, 2023, no capital gains-based incentive fees were contractually due and paid to the Adviser.

Table of Contents
In accordance with GAAP, accrual of the capital gains-based incentive fee is determined as if our investments had been liquidated at their fair values as of the end of the reporting period. Therefore, GAAP requires that the capital gains-based incentive fee accrual consider the aggregate unrealized capital appreciation in the calculation, as a capital gains-based incentive fee would be payable if such unrealized capital appreciation were realized. There can be no assurance that any such unrealized capital appreciation will be realized in the future. Accordingly, a GAAP accrual is calculated at the end of the reporting period based on (i) cumulative aggregate realized capital gains since our inception, plus (ii) the entire portfolio’s aggregate unrealized capital appreciation, if any, less (iii) cumulative aggregate realized capital losses since our inception, less (iv) the entire portfolio’s aggregate unrealized capital depreciation, if any. If such amount is positive at the end of a reporting period, a capital gains-based incentive fee equal to 20.0% of such amount, less the aggregate amount of capital gains-based incentive fees accrued in all prior years, is recorded, regardless of whether such amount is contractually due under the terms of the Advisory Agreement. If such amount is negative, then there is no accrual for such period and prior period accruals are reversed, as appropriate. During the three and six months ended September 30, 2023, we recorded capital gains-based incentive fees of $9.8 million and $9.9 million, respectively. During the three and six months ended September 30, 2022, we recorded a reversal of capital gains-based incentive fees of $1.7 million and $0.7 million, respectively, of previously accrued capital gains-based incentive fees.
Transactions with the Administrator
We reimburse the Administrator pursuant to the Administration Agreement for our allocable portion of the Administrator’s expenses incurred while performing services to us, which are primarily rent and salaries and benefits expenses of the Administrator’s employees, including our chief financial officer and treasurer, chief valuation officer, chief compliance officer, and general counsel and secretary, and their respective staffs. Two of our executive officers, David Gladstone (our chairman and chief executive officer) and Terry Lee Brubaker (our chief operating officer) serve as members of the board of managers and executive officers of the Administrator, which is 100% indirectly owned and controlled by Mr. Gladstone. Another of our officers, Mr. LiCalsi (our general counsel and secretary), serves as the Administrator’s president as well as the executive vice president of administration, general counsel, and secretary for the Adviser.
Our allocable portion of the Administrator’s expenses is generally derived by multiplying the Administrator’s total expenses by the approximate percentage of time during the current quarter the Administrator’s employees performed services for us in relation to their time spent performing services for all companies serviced by the Administrator. On July 11, 2023, our Board of Directors, including a majority of the directors who are not parties to the Administration Agreement or interested persons of either party, approved the annual renewal of the Administration Agreement through August 31, 2024. Administration fees for the three and six months ended September 30, 2023 were $0.3 million and $0.9 million, respectively. Administration fees for the three and six months ended September 30, 2022 were $0.6 million and $0.9 million, respectively.
Transactions with Gladstone Securities, LLC
Gladstone Securities, LLC (“Gladstone Securities”) is a privately held broker dealer registered with the Financial Industry Regulatory Authority and insured by the Securities Investor Protection Corporation. Gladstone Securities is an affiliate of ours, as its parent company is 100% owned and controlled by David Gladstone, our chairman and chief executive officer. Mr. Gladstone also serves on the board of managers of Gladstone Securities.
Other Transactions
From time to time, Gladstone Securities provides services, such as investment banking and due diligence services, to certain of our portfolio companies, for which it receives a fee. Any such fees paid by portfolio companies to Gladstone Securities do not impact the fees we pay to the Adviser or the non-contractual, unconditional, and irrevocable credits against the base management fee. During the six months ended September 30, 2023, the fees received by Gladstone Securities from our portfolio companies totaled $0.3 million. During the three and six months ended September 30, 2022, the fees received by Gladstone Securities from our portfolio companies totaled $1.0 million and $1.3 million, respectively.

NOTE 5. BORROWINGS
Revolving Line of Credit
On April 10, 2023, we, through our wholly-owned subsidiary, Business Investment, entered into Amendment No. 7 to the Credit Facility with KeyBank National Association (“KeyBank”) as administrative agent, lead arranger, managing agent and lender, the Adviser, as servicer, and certain other lenders party thereto. The reference rate was updated from LIBOR to Term SOFR plus an 11 basis point credit spread adjustment.
On March 8, 2021, we, through our wholly-owned subsidiary, Business Investment, entered into Amendment No. 6 to the Credit Facility. The revolving period was extended to February 29, 2024, and if not renewed or extended by such date, all principal and interest will be due and payable on February 28, 2026 (two years after the revolving period end date).
Advances under the Credit Facility generally bear interest at 30-day Term SOFR, subject to a floor of 0.35%, plus 2.85% per annum until February 29, 2024, with the margin then increasing to 3.10% for the period from February 29, 2024 to February 28, 2025, and increasing further to 3.35% thereafter with a SOFR credit spread adjustment of 11 basis points. The Credit Facility has an unused commitment fee on the daily unused commitment amount of 0.50% per annum if the average unused commitment amount for the period is less than or equal to 50% of the total commitment amount, 0.75% per annum if the average unused commitment amount for the period is greater than 50% but less than or equal to 65% of the total commitment amount, and 1.00% per annum if the average unused commitment amount for the period is greater than 65% of the total commitment amount.

(A)Availability is subject to various constraints, characteristics and applicable advance rates based on collateral quality under the Credit Facility, which equated to an adjusted availability of $100.7 million and $144.8 million as of September 30, 2023 and March 31, 2023, respectively.
(B)Excludes the impact of deferred financing costs and includes unused commitment fees.
Among other things, the Credit Facility contains a performance guaranty that requires us to maintain: (i) a minimum net worth of the greater of $210.0 million or $210.0 million plus 50% of all equity and subordinated debt raised, minus 50% of any equity or subordinated debt redeemed or retired after November 16, 2016, which equated to $328.5 million as of September 30, 2023; (ii) asset coverage with respect to senior securities representing indebtedness of at least 150% (or such percentage as may be set forth in Section 18 of the 1940 Act, as modified by Section 61 of the 1940 Act); and (iii) our status as a BDC under the 1940 Act and as a RIC under the Code. As of September 30, 2023, and as defined in the performance guaranty of the Credit Facility, we had a net worth of $805.9 million, asset coverage on our senior securities representing indebtedness of 211.5%, calculated in compliance with the requirements of Sections 18 and 61 of the 1940 Act, and an active status as a BDC and RIC. As of September 30, 2023, we were in compliance with all covenants under the Credit Facility.
Fair Value
We elected to apply the fair value option of ASC Topic 825, “Financial Instruments,” to the Credit Facility, which was consistent with our application of ASC 820 to our investments. Generally, the fair value of the Credit Facility is determined using a yield analysis, which includes a DCF calculation and also takes into account the assumptions the Valuation Team believes market participants would use, including the estimated remaining life, counterparty credit risk, current market yield and interest rate spreads of similar securities as of the measurement date. As of September 30, 2023, the discount rate used to determine the fair value of the Credit Facility was 30-day Term SOFR, with a 0.35% floor, plus 3.25% per annum, plus an unused commitment fee of 0.75%. As of March 31, 2023, the discount rate used to determine the fair value of the Credit Facility was 30-day LIBOR, with a 0.5% floor, plus 2.94% per annum, plus an unused commitment fee of 1.0%. Generally, an increase or decrease in the discount rate used in the DCF calculation may result in a corresponding decrease or increase, respectively, in the fair value of the Credit Facility. As of each of September 30, 2023 and March 31, 2023, the Credit Facility was valued using Level 3 inputs and any changes in its fair value are recorded in Net unrealized appreciation (depreciation) of other on our accompanying Consolidated Statements of Operations.

NOTE 6. REGISTRATION STATEMENT AND COMMON EQUITY OFFERINGS
Registration Statement
On September 3, 2021, we filed a registration statement on Form N-2 (File No. 333-259302), which the SEC declared effective on October 15, 2021. The registration statement permits us to issue, through one or more transactions, up to an aggregate of $300.0 million in securities, consisting of common stock, preferred stock, subscription rights, debt securities, and warrants to purchase common stock, preferred stock, or debt securities, including through concurrent, separate offerings of such securities. As of September 30, 2023, we had the ability to issue up to $215.6 million of the $300.0 million of securities registered under the registration statement.
Common Equity Offering
In August 2022, we entered into equity distribution agreements with Oppenheimer & Co. and Virtu Americas LLC (each a “Sales Agent”), under which we have the ability to issue and sell shares of our common stock, from time to time, through the Sales Agents, having an aggregate offering price of up to $50.0 million in what is commonly referred to as an “at-the-market” program (“Common Stock ATM Program”). In August 2023, we entered into an equity distribution agreement with B. Riley Securities, Inc. and entered into amendments to the agreements with Oppenheimer & Co. Inc. and Virtu Americas LLC in order to add B. Riley Securities, Inc. as a Sales Agent for the Common Stock ATM Program. As of September 30, 2023, we had remaining capacity to sell up to an additional $40.4 million of common stock under the Common Stock ATM program.
During the three and six months ended September 30, 2023, we sold 304,170 shares of our common stock under the Common Stock ATM Program at a weighted-average gross price of $13.55 per share, raising approximately $4.1 million of gross proceeds. The weighted-average net price per share, after deducting commissions and offering costs borne by us, was $13.35 and resulted in total net proceeds of approximately $4.1 million. These sales were above our then current estimated NAV per share.
During the three and six months ended September 30, 2022, we sold 29,640 shares of our common stock under the Common Stock ATM Program at a weighted-average gross price of $15.75 per share, raising approximately $0.5 million of gross proceeds.

NOTE 8. DISTRIBUTIONS TO COMMON STOCKHOLDERS
To qualify to be taxed as a RIC under Subchapter M of the Code, we must generally distribute to our stockholders, for each taxable year, at least 90% of our taxable ordinary income plus the excess of our net short-term capital gains over net long-term capital losses (“Investment Company Taxable Income”). The amount to be paid out as distributions to our stockholders is determined by our Board of Directors and is based upon management’s estimate of Investment Company Taxable Income and net long-term capital gains, as well as amounts to be distributed in accordance with Section 855(a) of the Code. Based on that estimate, our Board of Directors declares monthly distributions, and supplemental distributions, as appropriate, to stockholders each quarter and deemed distributions of long-term capital gains annually as of the end of the fiscal year, as applicable.
The U.S. federal income tax characteristics of cash distributions paid to our common stockholders generally are reported to stockholders on IRS Form 1099 after the end of each calendar year. Estimates of tax characterization made on a quarterly basis may not be representative of the actual tax characterization of cash distributions for the full year. Estimates made on a quarterly basis are updated as of each interim reporting date. If we determined the tax characterization of cash distributions paid to common stockholders during the current calendar year as of September 30, 2023, 72.7% would be from ordinary income and 27.3% would be from capital gains.
We paid the following cash distributions to our common stockholders for the six months ended September 30, 2023 and 2022:

Table of Contents
For the fiscal year ended March 31, 2023, Investment Company Taxable Income exceeded distributions declared and paid, and, in accordance with Section 855(a) of the Code, we elected to treat $21.4 million of the first distributions paid subsequent to fiscal year-end, as having been paid in the prior year. In addition, for the fiscal year ended March 31, 2023 net capital gains exceeded distributions declared and paid, and, in accordance with Section 855(a) of the Code, we elected to treat $10.6 million of the first distributions paid subsequent to fiscal year-end as having been paid in the prior year.
For the three months ended September 30, 2023, we recorded $0.5 million of net adjustments for estimated permanent book-tax differences to reflect tax character, which decreased Capital in excess of par value and increased Overdistributed net investment income on our accompanying Consolidated Statements of Assets and Liabilities. For the three months ended September 30, 2022, we recorded $0.4 million of net adjustments for estimated permanent book-tax differences to reflect tax character, which decreased Capital in excess of par value and increased Overdistributed net investment income and Accumulated net realized gain in excess of distributions on our accompanying Consolidated Statements of Assets and Liabilities.
For the six months ended September 30, 2023, we recorded $0.1 million of net adjustments for estimated permanent book-tax differences to reflect tax character, which increased Capital in excess of par value and Overdistributed net investment income and decreased Accumulated net realized gain in excess of distributions on our accompanying Consolidated Statements of Assets and Liabilities. For the six months ended September 30, 2022, we recorded $1.3 million of net adjustments for estimated permanent book-tax differences to reflect tax character, which decreased Capital in excess of par value and increased Overdistributed net investment income and Accumulated net realized gain in excess of distributions on our accompanying Consolidated Statements of Assets and Liabilities.
We may distribute our net long-term capital gains, if any, in cash or elect to retain some or all of such gains, pay taxes at the U.S. federal corporate-level income tax rate on the amount retained, and designate the retained amount as a “deemed distribution.” If we elect to retain net long-term capital gains and deem them distributed, each U.S. common stockholder will be treated as if they received a distribution of their pro-rata share of the retained net long-term capital gain and the U.S. federal income tax paid. As a result, each U.S. common stockholder will (i) be required to report their pro rata share of the retained gain on their tax return as long-term capital gain, (ii) receive a refundable tax credit for their pro-rata share of federal income tax paid by us on the retained gain, and (iii) increase the tax basis of their shares of common stock by an amount equal to the deemed distribution less the tax credit. For the year ended March 31, 2023, we did not elect to retain long-term capital gains and to treat them as deemed distributions to common stockholders.
NOTE 9. COMMITMENTS AND CONTINGENCIES
Legal Proceedings
We are party to certain legal proceedings incidental to the normal course of our business. We are required to establish reserves for litigation matters where those matters present loss contingencies that are both probable and estimable. When loss contingencies are not both probable and estimable, we do not establish reserves. Based on current knowledge, we do not believe that loss contingencies, if any, arising from pending investigations, litigation or regulatory matters will have a material adverse effect on our financial condition, results of operation or cash flows. Additionally, based on our current knowledge, we do not believe such loss contingencies are both probable and estimable and therefore, as of September 30, 2023 and March 31, 2023, we had no established reserves for such loss contingencies.
Escrow Holdbacks
From time to time, we enter into arrangements relating to exits of certain investments whereby specific amounts of the proceeds are held in escrow to be used to satisfy potential obligations, as stipulated in the sales agreements. We record escrow amounts in Restricted cash and cash equivalents, if received in cash but subject to potential obligations or other contractual restrictions, or as escrow receivables in Other assets, net, if not yet received in cash, on our accompanying Consolidated Statements of Assets and Liabilities. We establish reserves and holdbacks against escrow amounts if we determine that it is probable and estimable that a portion of the escrow amounts will not ultimately be released or received at the end of the escrow period. Reserves and holdbacks against escrow amounts were $31 thousand and $85 thousand as of September 30, 2023 and March 31, 2023, respectively.

Financial Commitments and Obligations
We may have line of credit commitments to certain of our portfolio companies that have not been fully drawn. Since these lines of credit commitments have expiration dates and we expect many will never be fully drawn, the total line of credit commitment amounts do not necessarily represent future cash requirements. We estimate the fair value of the combined unused line of credit commitments as of September 30, 2023 and March 31, 2023 to be insignificant.
The following table summarizes the principal balances of unused line of credit as of September 30, 2023 and March 31, 2023, which are not reflected as liabilities in the accompanying Consolidated Statements of Assets and Liabilities:

Revolving Line of Credit
On October 30, 2023, we, through our wholly-owned subsidiary, Business Investment, entered into Amendment No. 8 to the Credit Facility. Among other things, the revolving period was extended to October 30, 2026, and if not renewed or extended by such date, all principal and interest will be due and payable by October 30, 2028 (two years after the revolving period end date). Advances under the Credit Facility generally bear interest at 30-day Term SOFR, subject to a floor of 0.35%, plus 3.15% per annum until October 30, 2026, with the margin then increasing to 3.40% for the period from October 30, 2026 to October 30, 2027, and increasing further to 3.65% thereafter with a SOFR credit spread adjustment of 10 basis points. The Credit Facility has an unused commitment fee on the daily unused commitment amount of 0.50% per annum if the daily unused commitment amount is less than or equal to 50% of the total commitment amount, 0.75% per annum if the daily unused commitment amount is greater than 50% but less than or equal to 65% of the total commitment amount, and 1.00% per annum if the daily unused commitment amount is greater than 65% of the total commitment amount. The size of the Credit Facility was reduced from $180.0 million to $135.0 million.

OVERVIEW
General
We were incorporated under the General Corporation Law of the State of Delaware on February 18, 2005. On June 22, 2005, we completed our initial public offering and commenced operations. We operate as an externally managed, closed-end, non-diversified management investment company and have elected to be treated as a BDC under the Investment Company Act of 1940, as amended (the “1940 Act”). For U.S. federal income tax purposes, we have elected to be treated as a RIC under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). To continue to qualify as a RIC for U.S. federal income tax purposes and obtain favorable RIC tax treatment, we must meet certain requirements, including certain minimum distribution requirements.
We were established for the purpose of investing in debt and equity securities of established private businesses operating in the United States (“U.S.”). Our investment objectives are to: (i) achieve and grow current income by investing in debt securities of established businesses that we believe will provide stable earnings and cash flow to pay expenses, make principal and interest payments on our outstanding indebtedness, and make distributions to our stockholders that grow over time; and (ii) provide our stockholders with long-term capital appreciation in the value of our assets by investing in equity securities of established businesses, generally in combination with the aforementioned debt securities, that we believe can grow over time to permit us to sell our equity investments for capital gains. To achieve our objectives, our investment strategy is to invest in several categories of debt and equity securities, with individual investments generally totaling up to $75 million, although investment size may vary depending upon our total assets or available capital at the time of investment. We expect that our investment portfolio over time will consist of approximately 75% in debt investments and 25% in equity investments, at cost. As of September 30, 2023, our investment portfolio was comprised of 78.0% in debt investments and 22.0% in equity investments, at cost.
We focus on investing in lower middle market private businesses (which we generally define as companies with annual earnings before interest, taxes, depreciation and amortization (“EBITDA”) of $4 million to $15 million) (“Lower Middle Market”) in the U.S. that meet certain criteria, including: the sustainability of the business’ free cash flow and its ability to grow it over time, adequate assets for loan collateral, experienced management teams with a significant ownership interest in the portfolio company, reasonable capitalization of the portfolio company, including an ample equity contribution or cushion based on prevailing enterprise valuation multiples, and the potential to realize appreciation and gain liquidity in our equity position, if any. We anticipate that liquidity in our equity position will be achieved through a merger or acquisition of the portfolio company, a public offering of the portfolio company’s stock, or, to a lesser extent, by exercising our right to require the portfolio company to repurchase our warrants, though there can be no assurance that we will always have these rights. We invest in portfolio companies that seek funds for management buyouts and/or growth capital to finance acquisitions, recapitalize or, to a lesser extent, refinance their existing debt facilities. We seek to avoid investing in high-risk, early-stage enterprises.
We invest by ourselves or jointly with other funds and/or management of the portfolio company, depending on the opportunity. In July 2012, the SEC granted us an exemptive order (the “Co-Investment Order”) that expanded our ability to co-invest, under certain circumstances, with certain of our affiliates, including Gladstone Capital and any future BDC or closed-end management investment company that is advised (or sub-advised if it controls the fund) by the Adviser, or any combination of the foregoing, subject to the conditions in the Co-Investment Order. We believe the Co-Investment Order has enhanced and will continue to enhance our ability to further our investment objectives and strategies. If we are participating in an investment with one or more co-investors, whether or not an affiliate of ours, our investment is likely to be smaller than if we were investing alone.
We are externally managed by the Adviser, an investment adviser registered with the SEC and an affiliate of ours, pursuant to an investment advisory and management agreement (the “Advisory Agreement”). The Adviser manages our investment activities. We have also entered into an administration agreement with Gladstone Administration, LLC, an affiliate of ours and the Adviser, whereby we pay separately for administrative services.
Our shares of common stock, our 5.00% Notes due 2026 (“5.00% 2026 Notes”), our 4.875% Notes due 2028 ("4.875% 2028 Notes") and our 8.00% Notes due 2028 (“8.00% 2028 Notes”) are traded on the Nasdaq Global Select Market (“Nasdaq”) under the trading symbols “GAIN,” “GAINN,” "GAINZ" and “GAINL,” respectively.

Business
Portfolio Activity
While the business environment remains competitive, we continue to see new investment opportunities consistent with our investment strategy of providing a combination of debt and equity in support of management and independent sponsor-led buyouts of Lower Middle Market companies in the U.S. During the six months ended September 30, 2023, we invested in two new portfolio companies. From our initial public offering in June 2005 through September 30, 2023, we have invested in 58 companies, excluding investments in syndicated loans, for a total of approximately $1.7 billion, before giving effect to principal repayments and divestitures.
The majority of the debt securities in our portfolio have a success fee component, which enhances the yield on our debt investments. Unlike paid-in-kind (“PIK”) income, we generally do not recognize success fees as income until payment has been received. Due to the contingent nature of success fees, there are no guarantees that we will be able to collect any or all of these success fees or know the timing of any such collections. As a result, as of September 30, 2023, we had unrecognized, contractual success fees of $59.8 million, or $1.76 per common share. Consistent with accounting principles generally accepted in the U.S. (“GAAP”), we have not recognized success fee receivables and related income in our accompanying Consolidated Financial Statements until earned.
From inception through September 30, 2023, we completed sales of 29 portfolio companies that we acquired under our buyout strategy (which excludes investments in syndicated loans). In the aggregate, these sales have generated $261.4 million in net realized gains and $40.4 million in other income upon exit, for a total increase to our net assets of $301.9 million. We believe, in aggregate, these transactions were equity-oriented investment successes and exemplify our investment strategy of striving to achieve returns through current income on the debt portion of our investments and capital gains from the equity portion. The 29 liquidity events have offset any realized losses since inception, which were primarily incurred during the 2008-2009 recession in connection with the sale of performing syndicated loans at a realized loss to pay off a former lender. The successful exits, in part, enabled us to increase the monthly distribution run rate by 100.0% from March 2011 through September 30, 2023, and allowed us to declare and pay 20 supplemental distributions to common stockholders from March 2012 through September 30, 2023.
Capital Raising
We have been able to meet our capital needs through extensions of and increases to the Fifth Amended and Restated Credit Agreement dated April 30, 2013, as amended from time to time (the “Credit Facility”), and by accessing the capital markets in the form of public offerings of unsecured notes, as well as common and preferred stock. We have successfully extended the Credit Facility’s revolving period multiple times, most recently to October 2026, and currently have a total commitment amount of $135.0 million (with a potential total commitment of $300.0 million through additional commitments from new or existing lenders). During the six months ended September 30, 2023, we issued our 8.00% 2028 Notes for gross proceeds of $74.8 million and sold 304,170 shares of our common stock under our common stock "at-the-market" program (the "Common Stock ATM Program") for gross proceeds of approximately $4.1 million. During the year ended March 31, 2023, we sold 386,482 shares of our common stock under our Common Stock ATM program for gross proceeds of approximately $5.5 million. Refer to “Liquidity and Capital Resources — Revolving Line of Credit” for further discussion of the Credit Facility and to “Liquidity and Capital Resources — Equity — Common Stock” further discussion of our common stock.
Although we have been able to access the capital markets historically, market conditions may continue to affect the trading price of our common stock and thus our ability to finance new investments through the issuance of common equity. On September 30, 2023, the closing market price of our common stock was $12.74 per share, representing a 9.2% discount to our net asset value (“NAV”) of $14.03 per share as of September 30, 2023. When our common stock trades below NAV, our ability to issue additional equity is constrained by provisions of the 1940 Act, which generally prohibits the issuance and sale of our common stock at an issuance price below the then-current NAV per share without stockholder approval, other than through sales to our then-existing stockholders pursuant to a rights offering.

Regulatory Compliance
Our ability to seek external debt financing, to the extent that it is available under current market conditions, is further subject to the asset coverage limitations of the 1940 Act, which require us to have asset coverage (as defined in Sections 18 and 61 of the 1940 Act), of at least 150% on each of our senior securities representing indebtedness and our senior securities that are stock (such as our previously outstanding series of term preferred stock).
On April 10, 2018, our Board of Directors, including a “required majority” (as such term is defined in Section 57(o) of the 1940 Act) thereof, approved the modified asset coverage requirements set forth in Section 61(a)(2) of the 1940 Act. As a result, our asset coverage requirements for senior securities changed from 200% to 150%, effective as of April 10, 2019, one year after the date of the Board of Directors’ approval.
As of September 30, 2023, our asset coverage ratio on our senior securities representing indebtedness was 211.5%.

Revolving Line of Credit
On October 30, 2023, we, through our wholly-owned subsidiary, Gladstone Business Investment, LLC ("Business Investment"), entered into Amendment No. 8 to the Credit Facility. Among other things, the revolving period was extended to October 30, 2026, and if not renewed or extended by such date, all principal and interest will be due and payable in October 30, 2028 (two years after the revolving period end date). Advances under the Credit Facility generally bear interest at 30-day Term Secured Overinight Financing Rate ("SOFR"), subject to a floor of 0.35%, plus 3.15% per annum until October 30, 2026, with the margin then increasing to 3.40% for the period from October 30, 2026 to October 30, 2027, and increasing further to 3.65% thereafter with a SOFR credit spread adjustment of 10 basis points. The Credit Facility has an unused commitment fee on the daily unused commitment amount of 0.50% per annum if the daily unused commitment amount is less than or equal to 50% of the total commitment amount, 0.75% per annum if the daily unused commitment amount is greater than 50% but less than or equal to 65% of the total commitment amount, and 1.00% per annum if the daily unused commitment amount is greater than 65% of the total commitment amount. The facility size was reduced from $180.0 million to $135.0 million.
LIBOR Transition
As of June 30, 2023, the 30-day London Interbank Offered Rate ("LIBOR") was no longer readily available and each of our debt investments had transitioned from LIBOR as the applicable reference rate to 30-day SOFR. We anticipate originating future variable rate debt instruments using SOFR. We experienced minimal impacts on our operations as a result of the transition to SOFR.
Impact of Inflation
We believe the effects of inflation on our historical results of operations and financial condition have not been significant. During the six months ended September 30, 2023, general inflationary pressures and certain commodity price volatility have impacted certain of our portfolio companies to varying degrees; however, the broad based impact of these pricing changes have largely been mitigated by price adjustments without adverse sales implications, and thus, have not materially impacted our portfolio companies’ ability to service their indebtedness, including our loans. Notwithstanding the results to date, we expect that the cumulative effect of these inflationary pressures may impact the profit margins or sales of certain portfolio companies and their ability to service their debts. We continue to monitor the current inflationary environment to anticipate any impact on our portfolio companies, including their availability to pay interest on our loans. We cannot assure you that our results of operations and financial condition or that of our portfolio companies will not be materially impacted by inflation in the future.

Investment Income
Total investment income decreased $0.5 million, or 2.5%, for the three months ended September 30, 2023, as compared to the prior year period, due to a decrease in dividend and success fee income, partially offset by an increase in interest income.
Interest income from our investments in debt securities increased $6.0 million, or 42.4%, for the three months ended September 30, 2023, as compared to the prior year period. Generally, the level of interest income from investments is directly related to the principal balance of our interest-bearing investment portfolio outstanding during the period, multiplied by the weighted-average yield. The weighted-average principal balance of our interest-bearing investment portfolio during the three months ended September 30, 2023 was $543.8 million, compared to $467.0 million for the prior year period. This increase was primarily due to the $109.6 million of follow-on debt investments in existing portfolio companies, the origination of $85.8 million of new debt investments, and $14.9 million of loans returned to accrual status, partially offset by $9.4 million of pay-offs, restructurings, or write-offs of debt investments, and $9.2 million of loans placed on non-accrual status, after June 30, 2022, and their respective impact on the weighted-average principal balance when considering timing of new investments, pay-offs, restructurings, write-offs, and accrual status changes, as applicable.
The weighted-average yield on our interest-bearing investments, excluding cash and cash equivalents and receipts recorded as dividend and success fee income, was 14.6% for the three months ended September 30, 2023, compared to 12.1% for the prior year period. The weighted-average yield may vary from period to period, based on the current stated interest rate on interest-bearing investments, coupled with any collection of past due interest during the period.
As of September 30, 2023, our loans to Edge Adhesives Holdings, Inc. ("Edge"), J.R. Hobbs Co. – Atlanta, LLC ("J.R. Hobbs") and The Mountain Corporation ("The Mountain") were on non-accrual status, with an aggregate debt cost basis of $66.9 million. As of September 30, 2022, our loans to J.R. Hobbs and The Mountain were also on non-accrual status, with an aggregate debt cost basis of $63.4 million.
Dividend and success fee income for the three months ended September 30, 2023 decreased $6.6 million, or 100.0%, from the prior year period, as there was no dividend or success fee income during the three months ended September 30, 2023. During the three months ended September 30, 2022, dividend and success fee income consisted of $4.8 million of dividend income and $1.7 million of success fee income.
As of September 30, 2023 and March 31, 2023, no single investment represented greater than 10% of the total investment portfolio at fair value.
Expenses
Total expenses, net of any non-contractual, unconditional, and irrevocable credits from the Adviser, increased $12.6 million, or 134.6%, during the three months ended September 30, 2023, as compared to the prior year period, primarily due to an increase in incentive fees, interest expense and base management fee, partially offset by an increase in credits from the Adviser and a decrease in other expenses.
In accordance with GAAP, during the three months ended September 30, 2023, we recorded a $9.8 million capital gains-based incentive fee compared to a $1.7 million reversal of previously accrued capital gains-based incentive fee during the three months ended September 30, 2022. The capital gains-based incentive fee is a result of the net impact of net realized gains and net unrealized appreciation (depreciation) on investments during the respective periods. The income-based incentive fee decreased by $0.7 million, for the three months ended September 30, 2023, as compared to the prior year period, primarily due to a decrease in pre-incentive fee net investment income, partially offset by a decrease in net assets, which drives the hurdle rate. The base management fee, loan servicing fee, incentive fee, and their related non-contractual, unconditional, and irrevocable credits are computed quarterly, as described under “Transactions with the Adviser” in Note 4 — Related Party Transactions in the accompanying Notes to Consolidated Financial Statements and are summarized in the following table:

Interest expense increased $2.2 million, or 58.3%, during the three months ended September 30, 2023, as compared to the prior year period, primarily due to interest expense related to the 8.00% 2028 Notes issued in May 2023, not present in the prior year period, and increased interest rate and borrowings on the Credit Facility. The weighted-average balance outstanding under the Credit Facility during the three months ended September 30, 2023 was $50.4 million, compared to $11.7 million in the prior year period. The effective interest rate on the Credit Facility, excluding the impact of deferred financing costs, during the three months ended September 30, 2023 was 10.9%, as compared to 20.1% in the prior year period. The decrease in the effective interest rate on the Credit Facility was primarily a result of the decrease in the unused fee associated with the undrawn portion of the Credit Facility, partially offset by an increase in interest rates.
Other expenses decreased $0.6 million, or 33.7%, during the three months ended September 30, 2023, as compared to the prior year period, due to a decrease in professional fees and bad debt expense, partially offset by an increase in tax expense.

Net Realized Gain (Loss)
During the three months ended September 30, 2023, we recorded net realized gains on investments of $0.3 million related to a prior period exit. During the three months ended September 30, 2022, we recorded net realized gains on investments of $2.3 million, primarily due to a $2.2 million realized gain from the recapitalization of Horizon Facilities Services, Inc.and realized gains related to prior period exits of certain investments.

Net Unrealized Appreciation (Depreciation)
Net unrealized appreciation of investments of $48.7 million for the three months ended September 30, 2023 was primarily due to increased performance of certain of our portfolio companies and an increase in transaction multiples used to estimate the fair value of certain of our portfolio companies, in addition to increased fair value as a result of expected payoff amounts for certain investments. These increases were partially offset by decreased performance of certain of our other portfolio companies.
Net unrealized depreciation of investments of $10.6 million for the three months ended September 30, 2022 was primarily due to the decreased performance of certain of our portfolio companies and decreased comparable transaction multiples used to estimate the fair value of certain of our portfolio companies. These amounts were partially offset by increased performance of certain of our other portfolio companies, driven partially by the reversal of the impact of COVID-19 on certain of our portfolio companies and the markets in which they operate. In part, the performance of certain of our portfolio companies was driven by the impact COVID-19, and its variants, has had on our portfolio companies and the markets in which they operate, including government restrictions on the portfolio companies’ ability to operate under historical conditions, current and future shutdowns and reopening restrictions, operating challenges, including but not limited to, labor shortages, supply chain delays, increased material costs and demand for their products, and general economic outlook, or the reversal of such impact towards pre-COVID-19 levels.
Across our entire investment portfolio, we recorded net unrealized appreciation of $49.9 million on our equity positions and net unrealized depreciation of $1.2 million on our debt positions, for the three months ended September 30, 2023. As of September 30, 2023, the fair value of our investment portfolio was more than the cost basis by $80.8 million, as compared to June 30, 2023, when the fair value of our investment portfolio was more than the cost basis by $32.1 million, representing net unrealized appreciation of $48.7 million for the three months ended September 30, 2023. Our entire portfolio had a fair value of 109.7% of cost as of September 30, 2023.

Investment Income
Total investment income increased $0.5 million, or 1.2%, for the six months ended September 30, 2023, as compared to the prior year period, due to an increase in interest income, partially offset by a decrease in dividend and success fee income.
Interest income from our investments in debt securities increased $11.7 million, or 43.3%, for the six months ended September 30, 2023, as compared to the prior year period. Generally, the level of interest income from investments is directly related to the principal balance of our interest-bearing investment portfolio outstanding during the period, multiplied by the weighted-average yield.
The weighted-average principal balance of our interest-bearing investment portfolio during the six months ended September 30, 2023 was $519.7 million, compared to $449.1 million for the prior year period. This increase was primarily due to $116.3 million of follow-on debt investments in existing portfolio companies, the origination of $85.8 million of new debt investments, and $14.9 million of loans returned to accrual status, partially offset by $57.4 million of pay-offs, restructurings, or write-offs of debt investments and $9.2 million of loans placed on non-accrual status after March 31, 2022, and their respective impact on the weighted-average principal balance when considering timing of new investments, pay-offs, restructurings, write-offs, and accrual status changes, as applicable.
The weighted-average yield on our interest-bearing investments, excluding cash and cash equivalents and receipts recorded as dividend and success fee income, was 14.6% for the six months ended September 30, 2023, compared to 12.0% for the prior year period. The weighted-average yield may vary from period to period, based on the current stated interest rate on interest-bearing investments, coupled with any collection of past due interest during the period. During the six months ended September 30, 2023 and 2022, we had no collections of past due interest.
As of September 30, 2023, our loans to Edge, J.R. Hobbs and The Mountain were on non-accrual status, with an aggregate debt cost basis of $66.9 million. As of September 30, 2022, our loans to J.R. Hobbs and The Mountain were also on non-accrual status, with an aggregate debt cost basis of $63.4 million.
Dividend and success fee income for the six months ended September 30, 2023 decreased $11.2 million, or 85.5% from the prior year period. During the six months ended September 30, 2023, dividend and success fee income consisted of $1.9 million of dividend income. During the six months ended September 30, 2022, dividend and success fee income consisted primarily of $6.7 million of success fee income and $6.4 million of dividend income.
As of September 30, 2023, and March 31, 2023, no single investment represented greater than 10% of the total investment portfolio at fair value.
Expenses
Total expenses, net of any non-contractual, unconditional, and irrevocable credits from the Adviser, increased $12.6 million, or 59.0%, during the six months ended September 30, 2023, as compared to the prior year period, primarily due to an increase in incentive fees.
In accordance with GAAP, we recorded a $9.9 million capital gains-based incentive fee during the six months ended September 30, 2023, compared to a $0.7 million reversal of previously accrued capital gains-based incentive fee during the six months ended September 30, 2022. The capital gains-based incentive fee was a result of the net impact of net realized gains and net unrealized appreciation (depreciation) on investments during the respective periods. The income-based incentive fee decreased by $0.7 million for the six months ended September 30, 2023, as compared to the prior year period, primarily due to a decrease in pre-incentive fee net investment income, partially offset by a decrease in net assets, which drives the hurdle rate.

Interest expense increased $3.4 million, or 45.0%, during the six months ended September 30, 2023, as compared to the prior year period, primarily due to interest expense related to the 8.00% 2028 Notes issued in May 2023, not present in the prior year period, and increased interest rate and borrowings on the Credit Facility. The weighted-average balance outstanding on the Credit Facility during the six months ended September 30, 2023 was $47.0 million as compared to $5.9 million in the prior year period. The effective interest rate on the Credit Facility, excluding the impact of deferred financing costs, during the six months ended September 30, 2023 was 11.0%, as compared to 35.5% in the prior year period. The decrease in the effective interest rate on the Credit Facility was primarily a result of a decrease in unused commitment fees on the undrawn portion of the Credit Facility, partially offset by an increase in interest rates on the drawn portion of the Credit Facility.
Other expenses decreased $1.1 million, or 34.3%, during the six months ended September 30, 2023, as compared to the prior year period, due to a decrease in professional fees, bad debt expense and tax expense.

Net Realized Gain (Loss)
During the six months ended September 30, 2023, we recorded net realized gains on investments of $1.4 million, primarily due to $1.2 million of realized gains related to certain prior period exits and $0.3 million of realized gain from the recapitalization of Old World. During the six months ended September 30, 2022, we recorded net realized gains on investments of $6.8 million, primarily due to a $4.7 million realized gain from the exit of Bassett Creek, a $2.2 million realized gain from the recapitalization of Horizon and realized gains related to prior period exits of certain investments.
Net Unrealized Appreciation (Depreciation)
Net unrealized appreciation of investments of $47.9 million for the six months ended September 30, 2023 was primarily due to increased performance of certain of our portfolio companies and an increase in transaction multiples used to estimate the fair value of certain of our portfolio companies, in addition to increased fair value as a result of expected payoff amounts for certain investments. These increases were partially offset by decreased performance of certain of our other portfolio companies.
Net unrealized depreciation of investments of $10.4 million for the six months ended September 30, 2022 was primarily due to the reversal of unrealized appreciation of our investment in Bassett Creek upon its exit, partially offset by net unrealized appreciation across our portfolio. The net appreciation was driven primarily by increased performance of certain of our portfolio companies, driven partially by the reversal of the impact of COVID-19 on certain of our portfolio companies and the markets in which they operate. These amounts were partially offset by decreased performance of certain of our other portfolio companies and decreased comparable transaction multiples used to estimate the fair value of certain of our portfolio companies. These amounts were partially offset by increased performance of certain of our other portfolio companies, driven partially by the reversal of the impact of COVID-19 on certain of our portfolio companies and the markets in which they operate. In part, the performance of certain of our portfolio companies was driven by the impact COVID-19, and its variants, has had on our portfolio companies and the markets in which they operate, including government restrictions on the portfolio companies’ ability to operate under historical conditions, current and future shutdowns and reopening restrictions, operating challenges, including but not limited to, labor shortages, supply chain delays, increased material costs and demand for their products, and general economic outlook, or the reversal of such impact towards pre-COVID-19 levels.
Across our entire investment portfolio, we recorded net unrealized appreciation of $45.0 million on our equity positions and appreciation of $2.9 million on our debt positions, for the six months ended September 30, 2023. As of September 30, 2023, the fair value of our investment portfolio was more than the cost basis by $80.8 million, as compared to March 31, 2023, when the fair value of our investment portfolio was more than the cost basis by $32.9 million, representing net unrealized appreciation of $48.0 million for the six months ended September 30, 2023. Our entire portfolio had a fair value of 109.7% of cost as of September 30, 2023.

Financing Activities
Net cash provided by financing activities for the six months ended September 30, 2023 was $95.9 million, which consisted primarily of $74.8 million of gross proceeds from the issuance of our 8.00% 2028 Notes, $44.1 million of net borrowings under the Credit Facility and $4.1 million proceeds from issuance of common stock, net of expenses and shelf offering registration costs, partially offset by $24.3 million in distributions to common stockholders and $2.7 million of deferred financing and offering costs.
Net cash used in financing activities for the six months ended September 30, 2022 was $2.1 million, which consisted primarily of $18.9 million in distributions to common stockholders, partially offset by $16.6 million of net borrowings under the Credit Facility.
Distributions and Dividends to Stockholders
Common Stock Distributions
To qualify to be taxed as a RIC and thus avoid corporate level federal income tax on the income we distribute to our stockholders, we are required, among other requirements, to distribute to our stockholders on an annual basis at least 90% of our taxable ordinary income plus the excess of our net short-term capital gains over net long-term capital losses (“Investment Company Taxable Income”), determined without regard to the dividends paid deduction. Additionally, the Credit Facility generally restricts the amount of distributions to stockholders that we can pay out to be no greater than the sum of certain amounts, including our net investment income, plus net capital gains, plus amounts elected by the Company to be considered as having been paid during the prior fiscal year in accordance with Section 855(a) of the Code. In accordance with these requirements, our Board of Directors declared, and we paid, monthly cash distributions of $0.08 per common share for each of the six months from April through September 2023, and supplemental distributions of $0.12 per common share in June and September 2023. See also “Recent Developments - Distributions and Dividends” for a discussion of cash distributions to common stockholders declared by our Board of Directors in October 2023.
For the fiscal year ended March 31, 2023, Investment Company Taxable Income exceeded distributions declared and paid, and, in accordance with Section 855(a) of the Code, we elected to treat $21.4 million of the first distributions paid subsequent to fiscal year-end as having been paid in the prior year. In addition, for the fiscal year ended March 31, 2023, net capital gains exceeded distributions declared and paid, and, in accordance with Section 855(a) of the Code, we elected to treat $10.6 million of the first distributions paid subsequent to fiscal year-end as having been paid in the prior year. For the year ended March 31, 2023, we recorded $1.6 million of net adjustments for estimated permanent book-tax differences to reflect tax character, which decreased Capital in excess of par value and increased Overdistributed net investment income and Accumulated net realized gain in excess of distributions. For the six months ended September 30, 2023, we recorded $0.1 million of net adjustments for estimated permanent book-tax differences to reflect tax character, which increased Capital in excess of par value and Overdistributed net investment income and decreased Accumulated net realized gain in excess of distributions.
Dividend Reinvestment Plan
Our common stockholders who hold their shares through our transfer agent, Computershare, Inc. (“Computershare”), have the option to participate in a dividend reinvestment plan offered by Computershare, as the plan agent. This is an “opt in” dividend reinvestment plan, meaning that common stockholders may elect to have their cash distributions automatically reinvested in additional shares of our common stock. Common stockholders who do not make such election will receive their distributions in cash. Any distributions reinvested under the plan will be taxable to a common stockholder to the same extent, and with the same character, as if the common stockholder had received the distribution in cash. The common stockholder generally will have an adjusted basis in the additional common shares purchased through the plan equal to the dollar amount that would have been received if the U.S. stockholder had received the dividend or distribution in cash. The additional common shares will have a new holding period commencing on the day following the date on which the shares are credited to the common stockholder’s account. Computershare purchases shares in the open market in connection with the obligations under the plan.

Equity
Registration Statement
On September 3, 2021, we filed a registration statement on Form N-2 (File No. 333-259302), which the SEC declared effective on October 15, 2021. The registration statement permits us to issue, through one or more transactions, up to an aggregate of $300.0 million in securities, consisting of common stock, preferred stock, subscription rights, debt securities, and warrants to purchase common stock, preferred stock, or debt securities, including through concurrent, separate offerings of such securities. As of the date of this report, we have the ability to issue up to $215.6 million of the $300.0 million of securities registered under the registration statement.
Common Stock
In August 2022, we entered into equity distribution agreements with Oppenheimer & Co. and Virtu Americas LLC (each a “Sales Agent”), under which we have the ability to issue and sell shares of our common stock, from time to time, through the Sales Agents, having an aggregate offering price of up to $50.0 million in our Common Stock ATM Program. In August 2023, we entered into an equity distribution agreement with B. Riley Securities, Inc. and entered into amendments to the agreements with Oppenheimer & Co. Inc. and Virtu Americas LLC in order to add B. Riley Securities, Inc. as a Sales Agent for the Common Stock ATM Program. As of September 30, 2023, we had remaining capacity to sell up to an additional $40.4 million of common stock under the Common Stock ATM program.
During the three and six months ended September 30, 2023, we sold 304,170 shares of our common stock under the Common Stock ATM Program at a weighted-average gross price of $13.55 per share, raising approximately $4.1 million of gross proceeds. The weighted-average net price per share, after deducting commissions and offering costs borne by us, was $13.35 and resulted in total net proceeds of approximately $4.1 million. These sales were above our then current estimated NAV per share.
During the three and six months ended September 30, 2022, we sold 29,640 shares of our common stock under the Common Stock ATM Program at a weighted-average gross price of $15.75 per share and raised approximately $0.5 million of gross proceeds. The weighted-average net price per share, after deducting commissions and offering costs borne by us, was $15.59 and resulted in total net proceeds of approximately $0.5 million. These sales were above our then current estimated NAV per share.
We anticipate issuing equity securities to obtain additional capital in the future. However, we cannot determine the timing or terms of any future equity issuances or whether we will be able to issue equity on terms favorable to us, or at all. When our common stock is trading at a price below NAV per share, the 1940 Act places regulatory constraints on our ability to obtain additional capital by issuing common stock. Generally, the 1940 Act provides that we may not issue and sell our common stock at a price below our NAV per common share, other than to our then-existing common stockholders pursuant to a rights offering, without first obtaining approval from our stockholders and our independent directors and meeting other stated requirements. On September 30, 2023, the closing market price of our common stock was $12.74 per share, representing a 9.2% discount to our NAV per share of $14.03 as of September 30, 2023.
Revolving Line of Credit
Previously, on April 10, 2023, we, through our wholly-owned subsidiary, Business Investment, entered into Amendment No. 7 to the Credit Facility with KeyBank National Association (“KeyBank”) as administrative agent, lead arranger, managing agent and lender, the Adviser, as servicer, and certain other lenders party thereto. The reference rate was updated from LIBOR to Term SOFR plus an 11 basis point credit spread adjustment.
Previously, on March 8, 2021, we, through our wholly-owned subsidiary, Business Investment, entered into Amendment No. 6 to the Credit Facility with KeyBank as administrative agent, lead arranger, managing agent and lender, the Adviser, as servicer, and certain other lenders party thereto. The revolving period was extended to February 29, 2024, and if not renewed or extended by such date, all principal and interest will be due and payable on February 28, 2026 (two years after the revolving period end date).

Table of Contents
As of September 30, 2023, advances under the Credit Facility generally bore interest at 30-day SOFR, subject to a floor of 0.35%, plus 2.85% per annum until February 29, 2024, with the margin then increasing to 3.10% for the period from February 29, 2024 to February 28, 2025, and increasing further to 3.35% thereafter with a SOFR credit spread adjustment of 11 basis points. The Credit Facility has an unused commitment fee on the daily unused commitment amount of 0.50% per annum if the average unused commitment amount for the period is less than or equal to 50% of the total commitment amount, 0.75% per annum if the average unused commitment amount for the period is greater than 50% but less than or equal to 65% of the total commitment amount, and 1.00% per annum if the average unused commitment amount for the period is greater than 65% of the total commitment amount. At September 30, 2023, we had $79.3 million borrowings outstanding on the Credit Facility and as of the date of this report, we had $68.8 million outstanding under the Credit Facility.
Interest is payable monthly during the term of the Credit Facility. Available borrowings are subject to various constraints and applicable advance rates, which are generally based on the size, characteristics, and quality of the collateral pledged by Business Investment. The Credit Facility also requires that any interest and principal payments on pledged loans be remitted directly by the borrower into a lockbox account with KeyBank. KeyBank is also the trustee of the account and generally remits the collected funds to us once a month.
Among other things, the Credit Facility contains covenants that require Business Investment to maintain its status as a separate legal entity, prohibit certain significant corporate transactions (such as mergers, consolidations, liquidations or dissolutions) and restrict certain material changes to our credit and collection policies without the lenders’ consent. The Credit Facility also generally seeks to restrict distributions to stockholders to the sum of (i) our net investment income, (ii) net capital gains, and (iii) amounts deemed by the Company to be considered as having been paid during the prior fiscal year in accordance with Section 855(a) of the Code. Loans eligible to be pledged as collateral are subject to certain limitations, including, among other things, restrictions on geographic concentrations, industry concentrations, loan size, payment frequency and status, average life, portfolio company leverage, and lien property. The Credit Facility also requires Business Investment to comply with other financial and operational covenants, which obligate Business Investment to, among other things, maintain certain financial ratios, including asset and interest coverage and a minimum number of obligors required in the borrowing base. Additionally, the Credit Facility contains a performance guaranty that requires the Company to maintain (i) a minimum net worth of the greater of $210.0 million or $210.0 million plus 50% of all equity and subordinated debt raised, minus 50% of any equity or subordinated debt redeemed or retired after November 16, 2016, which equated to $328.5 million as of September 30, 2023, (ii) asset coverage with respect to senior securities representing indebtedness of at least 150% (or such percentage as may be set forth in Section 18 of the 1940 Act, as modified by Section 61 of the 1940 Act), and (iii) our status as a BDC under the 1940 Act and as a RIC under the Code. As of September 30, 2023, and as defined in the performance guaranty of the Credit Facility, we had a net worth of $805.9 million, asset coverage on our senior securities representing indebtedness of 211.5%, calculated in compliance with the requirements of Sections 18 and 61 of the 1940 Act, and an active status as a BDC and RIC. As of September 30, 2023, we had availability, after adjustments for various constraints based on collateral quality, of $100.7 million under the Credit Facility and were in compliance with all covenants under the Credit Facility.

OFF-BALANCE SHEET ARRANGEMENTS
Unlike PIK income, we generally do not recognize success fees as income until payment has been received. Due to the contingent nature of success fees, there are no guarantees that we will be able to collect any or all of these success fees or know the timing of any such collections. As a result, as of September 30, 2023 and March 31, 2023, we had unrecognized, contractual off-balance sheet success fee receivables of $59.8 million and $53.6 million (or approximately $1.76 and $1.60 per common share), respectively, on our debt investments. Consistent with GAAP, we have not recognized success fee receivables and related income in our accompanying Consolidated Financial Statements until earned.
CONTRACTUAL OBLIGATIONS
We have line of credit commitments to certain of our portfolio companies that have not been fully drawn. Since these line of credit commitments have expiration dates and we expect many will never be fully drawn, the total line of credit commitment amounts do not necessarily represent future cash requirements. We estimate the fair value of the combined unused line of credit commitments as of September 30, 2023 to be insignificant.
The following table shows our contractual obligations as of September 30, 2023, at cost:

|  | Payments Due by Period
Contractual Obligations(A) |  | Total |  | Less than 1 Year |  | 1-3 Years |  | 3-5 Years |  | More than 5 Years

Critical Accounting Estimates
The preparation of financial statements and related disclosures in conformity with GAAP requires management to make estimates and assumptions that affect the reported consolidated amounts of assets and liabilities, including disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the period reported. Actual results could differ materially from those estimates under different assumptions or conditions. We have identified our investment valuation policy (which has been approved by our Board of Directors) as our most critical accounting policy, which is described in Note 2 — Summary of Significant Accounting Policies in the accompanying Notes to Consolidated Financial Statements included elsewhere in this Quarterly Report. Additionally, refer to Note 3 — Investments in the accompanying Notes to Consolidated Financial Statements included elsewhere in this Quarterly Report for additional information regarding fair value measurements and our application of Financial Accounting Standards Board Accounting Standards Codification Topic 820, “Fair Value Measurements and Disclosures.” We have also identified our revenue recognition policy as a critical accounting policy, which is described in Note 2 — Summary of Significant Accounting Policies in the accompanying Notes to Consolidated Financial Statements included elsewhere in this Quarterly Report.

Investment Valuation
Credit Monitoring and Risk Rating
The Adviser monitors a wide variety of key credit statistics that provide information regarding our portfolio companies to help us assess credit quality and portfolio performance and, in some instances, are used as inputs in our valuation techniques. Generally, we, through the Adviser, participate in periodic board meetings of our portfolio companies in which we hold board seats and also require them to provide annual audited and monthly unaudited financial statements. Using these statements or comparable information and board discussions, the Adviser calculates and evaluates certain credit statistics.
The Adviser risk rates all of our investments in debt securities. The Adviser does not risk rate equity securities. For loans that have been rated by a SEC-registered Nationally Recognized Statistical Rating Organization (“NRSRO”), the Adviser generally uses the average of two corporate level NRSRO’s risk ratings for such security. For all other debt securities, the Adviser uses a proprietary risk rating system. While the Adviser seeks to mirror the NRSRO systems, we cannot provide any assurance that the Adviser’s risk rating system will provide the same risk rating as an NRSRO for these securities. The Adviser’s risk rating system is used to estimate the probability of default on debt securities and the expected loss, if there is a default. The Adviser’s risk rating system uses a scale of 0 to >10, with >10 being the lowest probability of default. It is the Adviser’s understanding that most debt securities of Lower Middle Market companies do not exceed the grade of BBB on an NRSRO scale, so there would be no debt securities in the Lower Middle Market that would meet the definition of AAA, AA or A. Therefore, the Adviser’s scale begins with the designation >10 as the best risk rating which may be equivalent to a BBB from an NRSRO; however, no assurance can be given that a >10 on the Adviser’s scale is equal to a BBB or Baa2 on an NRSRO scale. The Adviser’s risk rating system covers both qualitative and quantitative aspects of the business and the securities we hold.
The following table reflects risk ratings for all loans in our portfolio as of September 30, 2023 and March 31, 2023:

Rating |  | September 30, 2023 |  | March 31, 2023
Highest |  | 9.0 |  | 9.0
Average |  | 6.5 |  | 6.4
Weighted-average |  | 6.9 |  | 7.3
Lowest |  | 1.0 |  | 1.0

Tax Status
We intend to continue to maintain our qualification as a RIC under Subchapter M of the Code for U.S. federal income tax purposes. As a RIC, we generally are not subject to U.S. federal income tax on the portion of our taxable income and gains distributed to our stockholders. To maintain our qualification as a RIC, we must maintain our status as a BDC and meet certain source-of-income and asset diversification requirements. In addition, to qualify to be taxed as a RIC, we must distribute to stockholders at least 90% of our Investment Company Taxable Income, determined without regard to the dividends paid deduction. Our policy generally is to make distributions to our stockholders in an amount up to 100% of Investment Company Taxable Income. We may retain some or all of our net long-term capital gains, if any, and designate them as deemed distributions, or distribute such gains to stockholders in cash. See “— Liquidity and Capital Resources — Distributions and Dividends to Stockholders.”
In an effort to limit federal excise taxes, we have to distribute to stockholders, during each calendar year, an amount close to the sum of: (1) 98% of our ordinary income for the calendar year, (2) 98.2% of our net capital gains (both long-term and short-term), if any, for the one-year period ending on October 31 of the calendar year, and (3) any income realized, but not distributed, in the preceding period (to the extent that income tax was not imposed on such amounts), less certain reductions, as applicable. Under the RIC Modernization Act, we are permitted to carryforward any capital losses that we may incur for an unlimited period, and such capital loss carryforwards will retain their character as either short-term or long-term capital losses. Our capital loss carryforward balance was $0 as of both September 30, 2023 and March 31, 2023.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Market risk includes risks that arise from changes in interest rates, foreign currency exchange rates, commodity prices, equity prices and other market changes that affect market sensitive instruments. The prices of securities held by us may decline in response to certain events, including those directly involving the companies whose securities are owned by us; conditions affecting the general economy, including public health emergencies; overall market changes; local, regional or global political, social or economic instability; and interest rate fluctuations.
The primary risk we believe we are exposed to is interest rate risk. Because we borrow money to make investments, our net investment income is dependent upon the difference between the rates at which we borrow funds, such as under the Credit Facility (which is variable) and our unsecured notes (which are fixed), and the rates at which we invest those funds. As a result, there can be no assurance that a significant change in market interest rates will not have a material adverse effect on our net investment income. We use a combination of debt and equity capital to finance our investing activities. We may use interest rate risk management techniques to limit our exposure to interest rate fluctuations. Such techniques may include various interest rate hedging activities to the extent permitted by the 1940 Act.
We target to have approximately 90% of the loans in our portfolio at variable rates or variable rates with a floor mechanism, and up to approximately 10% at fixed rates. As of September 30, 2023 and March 31, 2023, all of our variable-rate loans have rates associated with the current 30-day SOFR rate and 30-day LIBOR rate, respectively, and our total debt investment portfolio consisted of the following breakdown based on the principal balance:

Rates: |  | September 30, 2023 |  | March 31, 2023
Variable rates with a floor |  | 100.0 | % |  | 100.0 | %
Fixed rates |  | — |  |  | — | %
Total |  | 100.0 | % |  | 100.0 | %

There have been no material changes in the quantitative and qualitative market risk disclosures during the six months ended September 30, 2023 from those included in our Annual Report.
ITEM 4. CONTROLS AND PROCEDURES.
a)Evaluation of Disclosure Controls and Procedures
As of September 30, 2023 (the end of the period covered by this report), we, including our chief executive officer and chief financial officer, evaluated the effectiveness, design and operation of our disclosure controls and procedures. Based on that evaluation, our management, including the chief executive officer and chief financial officer, concluded that our disclosure controls and procedures were effective at a reasonable assurance level in timely alerting management, including the chief executive officer and chief financial officer, of material information about us required to be included in periodic SEC filings. However, in evaluation of the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
b)Changes in Internal Control over Financial Reporting
There were no changes in internal controls for the three months ended September 30, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS.
From time to time, we may become involved in various investigations, claims and legal proceedings that arise in the ordinary course of our business. Furthermore, third parties may try to seek to impose liability on us in connection with the activities of our portfolio companies. While we do not expect that the resolution of these matters, if they arise, would materially affect our business, financial condition, results of operations or cash flows, resolution will be subject to various uncertainties and could result in the expenditure of significant financial and managerial resources. Further, we are not named as a party to any proceeding that involves a claim for damages that exceeds 10% of our consolidated current assets.
ITEM 1A. RISK FACTORS.
Our business is subject to certain risks and events that, if they occur, could adversely affect our financial condition and results of operations and the trading price of our securities.
