Note 1. Organization
TriplePoint Venture Growth BDC Corp. (the “Company”), a Maryland corporation, was formed on June 28, 2013 and commenced investment operations on March 5, 2014. The Company is structured as an externally-managed, closed-end 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”). The Company has elected to be treated, and intends to qualify annually, as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”).
The Company was formed to expand the venture growth stage business segment of TriplePoint Capital LLC’s (“TPC”) investment platform. TPC is widely recognized as a leading global financing provider devoted to serving venture capital-backed companies with creative, flexible and customized debt financing, equity capital and complementary services throughout their lifespan. The Company’s investment objective is to maximize its total return to stockholders primarily in the form of current income and, to a lesser extent, capital appreciation by lending primarily with warrants to venture growth stage companies focused in technology and other high growth industries backed by TPC’s select group of leading venture capital investors. The Company is externally managed by TriplePoint Advisers LLC (the “Adviser”), which is registered as an investment adviser under the Investment Advisers Act of 1940, as amended, and is a wholly owned subsidiary of TPC. The Adviser is responsible for sourcing, reviewing and structuring investment opportunities, underwriting and performing due diligence on investments and monitoring the investment portfolio on an ongoing basis. The Adviser was organized in August 2013 and, pursuant to an investment advisory agreement entered into between the Company and the Adviser, the Company pays the Adviser a base management fee and an incentive fee for its services. The Company has also entered into an administration agreement with TriplePoint Administrator LLC (the “Administrator”), a wholly owned subsidiary of the Adviser, and reimburses the Administrator for the costs incurred by the Administrator in connection with the services it provides under an administration agreement (the “Administration Agreement”).
The Company has two wholly owned subsidiaries: TPVG Variable Funding Company LLC (the “Financing Subsidiary”), a bankruptcy remote special purpose entity established for utilizing the Company’s revolving credit facility whose creditors have a claim on its assets prior to those assets becoming available to the Financing Subsidiary’s equity holder, and TPVG Investment LLC, an entity established for holding certain of the Company’s investments without negatively impacting the Company’s RIC tax status. These subsidiaries are consolidated in the financial statements of the Company.

Investment Advisory Agreement
In accordance with the Board approved investment advisory agreement (the “Advisory Agreement”), subject to the overall supervision of the Board and in accordance with the 1940 Act, the Adviser manages the day-to-day operations and provides investment advisory services to the Company. Under the terms of the Advisory Agreement, the Adviser:
•determines the composition of the Company’s portfolio, the nature and timing of changes to the Company’s portfolio and the manner of implementing such changes;
•identifies, evaluates and negotiates the structure of investments;
•executes, closes, services and monitors investments;
•determines the securities and other assets purchased, retained or sold;
•performs due diligence on prospective investments; and
•provides the Company with such other investment advisory, research and related services as the Company may, from time to time, reasonably require for the investment of its funds.
As consideration for the investment advisory and management services provided, and pursuant to the Advisory Agreement, the Company has agreed to pay the Adviser a fee consisting of two components—a base management fee and an incentive fee. The cost of both the base management fee and incentive fee is ultimately borne by the Company’s stockholders.
Base Management Fee
The base management fee is calculated at an annual rate of 1.75% of the Company’s average adjusted gross assets, including assets purchased with borrowed funds. For services rendered under the Advisory Agreement, the base management fee is payable quarterly in arrears. The base management fee is calculated based on the average value of the Company’s gross assets at the end of its two most recently completed calendar quarters. Such amount is appropriately adjusted (based on the actual number of days elapsed relative to the total number of days in such calendar quarter) for any share issuances or repurchases during a calendar quarter. Base management fees for any partial month or quarter are appropriately pro-rated.
Incentive Fee
The incentive fee, which provides the Adviser with a share of the income it generates for the Company, consists of two components—net investment income and net capital gains—which are largely independent of each other, and may result in one component being payable in a given period even if the other is not payable.
Under the investment income component, the Company pays the Adviser each quarter 20.0% of the amount by which the Company’s pre-incentive fee net investment income for the quarter exceeds a hurdle rate of 2.0% (8.0% annualized) of the Company’s net assets at the end of the immediately preceding calendar quarter, subject to a “catch-up” provision pursuant to which the Adviser receives all of such income in excess of 2.0% but less than 2.5%, subject to a total return requirement. The effect of the “catch-up” provision is that, subject to the total return provision discussed below, if pre-incentive fee net investment income exceeds 2.5% in any calendar quarter, the Adviser receives 20.0% of the Company’s pre-incentive fee net investment income as if the 2.0% hurdle rate did not apply. Pre-incentive fee net investment income does not include any realized capital gains, realized capital losses or unrealized capital gains or losses. The foregoing incentive fee is subject to a total return requirement, which provides that no incentive fee in respect of the Company’s pre-incentive fee net investment income is payable except to the extent that 20.0% of the cumulative net increase in net assets resulting from operations since the effective date of the Company’s election to be regulated as a BDC exceeds the cumulative incentive fees accrued and/or paid since the effective date of the Company’s election to be regulated as a BDC. In other words, any investment income incentive fee that is payable in a calendar quarter is limited to the lesser of (i) 20.0% of the amount by which the Company’s pre-incentive fee net investment income for such calendar quarter exceeds the 2.0% hurdle, subject to the “catch-up” provision and (ii) (x) 20.0% of the cumulative net increase in net assets resulting from operations since the effective date of the Company’s election to be regulated as a BDC minus (y) the cumulative incentive fees accrued and/or paid since the effective date of the Company’s election to be regulated as a BDC. For the foregoing purpose, the “cumulative net increase in net assets resulting from operations” is the sum of the Company’s pre-incentive fee net investment income, realized gains and losses and unrealized appreciation and depreciation since the effective date of the Company’s election to be regulated as a BDC. The Company elected to be regulated as a BDC under the 1940 Act on March 5, 2014.
Under the capital gains component of the incentive fee, the Company pays the Adviser at the end of each calendar year (or upon termination of the Advisory Agreement) 20.0% of the Company’s aggregate cumulative realized capital gains from inception through the end of that year (or upon termination of the Advisory Agreement), computed net of aggregate cumulative realized capital losses and aggregate cumulative unrealized losses through the end of such year, less the aggregate amount of any previously paid capital gain incentive fees. For the foregoing purpose, the Company’s “aggregate cumulative realized capital gains” does not include any unrealized gains. It should be noted that the Company accrues an incentive fee for accounting purposes taking into account any unrealized gains in accordance with GAAP. The capital gains component of the incentive fee is not subject to any minimum return to stockholders. If such amount is negative, then no capital gains incentive fee is payable for such year. Additionally, if the Advisory Agreement is terminated as of a date that is not a calendar year end, the termination date will be treated as though it were a calendar year end for purposes of calculating and paying the capital gains incentive fee.
The base management fee, income incentive fee and capital gains incentive fee earned by the Adviser are included in the Company’s consolidated financial statements and summarized in the table below. Base management and incentive fees are paid in the quarter following that in which they are earned. The Company had cumulative realized and unrealized losses as of September 30, 2022 and 2021, and, as a result, no capital gains incentive fees were recorded for the three and nine months ended September 30, 2022 and 2021.

Administration Agreement
The Board-approved administration agreement (the “Administration Agreement”) provides that the Administrator is responsible for furnishing the Company with office facilities and equipment and providing the Company with clerical, bookkeeping, recordkeeping services and other administrative services at such facilities. Under the Administration Agreement, the Administrator performs, or oversees, or arranges for, the performance of the Company’s required administrative services, which includes being responsible for the financial and other records which the Company is required to maintain and preparing reports to the Company’s stockholders and reports and other materials filed with the SEC and any other regulatory authority. In addition, the Administrator assists the Company in determining and publishing net asset value (“NAV”), overseeing the preparation and filing of the Company’s tax returns and printing and disseminating reports and other materials to the Company’s stockholders, and generally oversees the payment of the Company’s expenses and the performance of administrative and professional services rendered to the Company by others. Under the Administration Agreement, the Administrator also provides significant managerial assistance on the Company’s behalf to those companies that have accepted the Company’s offer to provide such assistance.
In full consideration of the provision of the services of the Administrator, the Company reimburses the Administrator for the costs and expenses incurred by the Administrator in performing its obligations and providing personnel and facilities under the Administration Agreement. Payments under the Administration Agreement are equal to the Company’s allocable portion (subject to the review of the Board) of the Administrator’s overhead resulting from its obligations under the Administration Agreement, including rent and the allocable portion of the cost of the chief compliance officer and chief financial officer and their respective staffs. In addition, if requested to provide significant managerial assistance to the Company’s portfolio companies, the Administrator is paid an additional amount based on the services provided, which shall not exceed the amount the Company receives from such companies for providing this assistance.
For the three and nine months ended September 30, 2022, expenses paid or payable by the Company to the Administrator under the Administration Agreement were $0.6 million and $1.7 million, respectively.
For the three and nine months ended September 30, 2021, expenses paid or payable by the Company to the Administrator under the Administration Agreement were $0.5 million and $1.5 million, respectively.

Investments, Debt and Equity Securities [Abstract]  
Investments Investments
The Company measures the fair value of its investments in accordance with Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosure, or “ASC Topic 820,” issued by the FASB. ASC Topic 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.
The Valuation Committee of the Board is responsible for assisting the Board in valuing investments for which current market quotations are not readily available. Investments for which market quotations are readily available are valued using market quotations, which are generally obtained from pricing services, broker-dealers or market makers.
The Company values its investments for which market quotations are not readily available at fair value as determined in good faith by the Board, with the assistance of the Adviser and independent valuation agents, in accordance with Rule 2a-5 of the 1940 Act and GAAP, and in accordance with the Company’s valuation methodologies. If more than one valuation method is used to measure fair value, the results are evaluated and weighted, as appropriate, considering the reasonableness of the range indicated by those results. The Adviser considers a range of fair values based upon the valuation techniques utilized and selects a value within that range that most accurately represents fair value based on current market conditions as well as other factors the Adviser’s valuation committee considers relevant. The Board determines fair value of its investments on at least a quarterly basis or at such other times when the Board feels it would be appropriate to do so given the circumstances. A determination of fair value involves subjective judgments and estimates and depends on the facts and circumstances present at each valuation date. Due to the inherent uncertainty of determining fair value of portfolio investments that do not have a readily available market value, fair value of investments may differ significantly from the values that would have been used had a readily available market value existed for such investments, and the differences could be material.
ASC Topic 820 specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. ASC Topic 820 also provides guidance regarding a fair value hierarchy, which prioritizes information used to measure fair value and the effect of fair value measurements on earnings and provides for enhanced disclosures determined by the level of information used in the valuation. In accordance with ASC Topic 820, these inputs are summarized in the three levels listed below.
Level 1—Valuations are based on quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date.
Level 2—Valuations are based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly and model-based valuation techniques for which all significant inputs are observable.
Level 3—Valuations are based on inputs that are unobservable and significant to the overall fair value measurement. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models incorporating significant unobservable inputs, such as discounted cash flow models and other similar valuations techniques. The valuation of Level 3 assets and liabilities generally requires significant management judgment due to the inability to observe inputs to valuation.
In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment’s level within the fair value hierarchy is based on the lowest level of observable input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to the investment.
Under ASC Topic 820, the fair value measurement also assumes that the transaction to sell an asset occurs in the principal market for the asset or, in the absence of a principal market, the most advantageous market for the asset, which may be a hypothetical market, excluding transaction costs. The principal market for any asset is the market with the greatest volume and level of activity for such asset in which the reporting entity would or could sell or transfer the asset. In determining the principal market for an asset or liability under ASC Topic 820, it is assumed that the reporting entity has access to such market as of the measurement date. Market participants are defined as buyers and sellers in the principal or most advantageous market that are independent, knowledgeable and willing and able to transact.
For purposes of Section 2(a)(41) and Rule 2a-5 under the 1940 Act, a market quotation is readily available only when that quotation is a quoted price (unadjusted) in active markets for identical investments that the Company can access at the measurement date, provided that a quotation will not be readily available if it is not reliable. Any portfolio investment that is not priced using a Level 1 input shall be subject to the fair value determination requirements under Rule 2a-5 and subject to the Company’s valuation procedures.
With respect to investments for which market quotations are not readily available, the Board undertakes a multi-step valuation process each quarter, as described below:
•The quarterly valuation process begins with each portfolio company or investment receiving a proposed valuation by the Adviser. The Adviser’s internal valuation committee (the “Adviser Valuation Committee”) is responsible for the valuation process, including making preliminary valuation conclusions and recommendations to the Valuation Committee and Board. The Adviser Valuation Committee does not include any voting members who are portfolio managers or investment professionals.
•The Adviser’s Portfolio Valuation, Monitoring and Analytics (“VMA”) group is responsible for aiding and supporting the Adviser Valuation Committee in the Adviser Valuation Committee’s role of overseeing the valuation process, including for calculating and overseeing the valuation process and valuation conclusions, and including making recommendations with respect to discount rates, liquidity adjustments and other key inputs into the valuation process.
•Proposed valuations are then documented and discussed with the Adviser Valuation Committee and other members of the Adviser’s senior management, including members of the VMA and the Adviser’s Finance, Operations, Legal and Compliance groups.
•At least once annually, the valuation for each portfolio investment is reviewed by an independent third-party valuation firm. However, the Board does not have de minimis investments of less than 1.0% of the Company’s gross assets (up to an aggregate of 10% of the Company’s gross assets) independently reviewed.
•The Adviser and the independent third-party valuation firms, if applicable, then present their proposed valuations to the Valuation Committee and Board, and the Board makes a fair valuation determination for each portfolio investment that is to be fair valued.
Debt Investments
The debt investments identified on the consolidated schedules of investments are loans and equipment leases made to venture growth stage companies focused in technology, life sciences and other high growth industries which are backed by a select group of leading venture capital investors. These investments are considered Level 3 assets under ASC Topic 820 as there is no known or accessible market or market indices for these types of debt instruments and thus the Adviser’s senior management team must estimate the fair value of these investment securities based on models utilizing unobservable inputs.
To estimate the fair value of debt investments, the Company compares the cost basis of each debt investment, including any OID, to the resulting fair value determined using a discounted cash flow model, unless another model is more appropriate based on the circumstances at the measurement date. The discounted cash flow approach entails analyzing the interest rate spreads for recently completed financing transactions which are similar in nature to these debt investments, in order to determine a comparable range of effective market interest rates. The range of interest rate spreads utilized is based on borrowers with similar credit profiles. All remaining expected cash flows of the investment are discounted using the range of interest rates to determine a range of fair values for the debt investment.
The valuation process includes, among other things, evaluating the underlying investment performance of the portfolio company’s current financial condition and ability to raise additional capital, as well as macro-economic events that may impact valuations. These events include, but are not limited to, current market yields and interest rate spreads of similar securities as of the measurement date. Changes in these unobservable inputs could result in significantly different fair value measurements.
Under certain circumstances, an alternative technique may be used to value certain debt investments that better reflect the fair value of the investment, such as the price paid or realized in a recently completed transaction or a binding offer received in an arm’s length transaction, the use of multiple probability weighted cash flow models when the expected future cash flows contain elements of variability or estimates of proceeds that would be received in a liquidation scenario.
Warrant Investments
Warrant fair values are primarily determined using a Black Scholes option pricing model. Privately held warrants and equity-related securities are valued based on an analysis of various factors, including, but not limited to, those listed below. Increases or decreases in any of the unobservable inputs described below could result in a material change in fair value:
•Underlying enterprise value of the issuer based on available information, including any information regarding the most recent financing round of borrower. Valuation techniques to determine enterprise value include market multiple approaches, income approaches or the use of recent rounds of financing and the portfolio company’s capital structure. Valuation techniques are also utilized to allocate the enterprise fair value of a portfolio company to the specific class of common or preferred stock exercisable in the warrant. Such techniques take into account the rights and preferences of the portfolio company’s securities, expected exit scenarios, and volatility associated with such outcomes to allocate the fair value to the specific class of stock held in the portfolio. Such techniques include option pricing models, including back solve techniques, probability weighted expected return models and other techniques determined to be appropriate.
•Volatility, or the amount of uncertainty or risk about the size of the changes in the warrant investment price, is based on comparable publicly traded companies within indices similar in nature to the underlying company issuing the warrant.
•The risk-free interest rates are derived from the U.S. Treasury yield curve. The risk-free interest rates are calculated based on a weighted average of the risk-free interest rates that correspond closest to the expected remaining life of the warrant investment.
•Other adjustments, including a marketability discount on private company warrant investments, are estimated based on the Adviser’s judgment about the general industry environment.
•Historical portfolio experience on cancellations and exercises of warrant investments are utilized as the basis for determining the estimated life of the warrant investment in each financial reporting period. Warrant investments may be exercised in the event of acquisitions, mergers or initial public offerings, and cancelled due to events such as bankruptcies, restructuring activities or additional financings. These events cause the expected remaining life assumption to be shorter than the contractual term of the warrant investment.
Under certain circumstances alternative techniques may be used to value certain warrants that more accurately reflect the warrants' fair values, such as an expected settlement of a warrant in the near term, a model that incorporates a put feature associated with the warrant, or the price paid or realized in a recently completed transaction or binding offer received in an arm’s-length transaction. The fair value may be determined based on the expected proceeds to be received from such settlement or based on the net present value of the expected proceeds from the put option.
Equity Investments
The fair value of an equity investment in a privately held company is initially the amount invested. The Company adjusts the fair value of equity investments in private companies upon the completion of a new third party round of equity financing subsequent to its investment. The Company may adjust the fair value of an equity investment absent a new equity financing event based upon positive or negative changes in a portfolio company’s financial or operational performance. The Company may also reference comparable transactions and/or secondary market transactions of comparable companies to estimate fair value. These valuation methodologies involve a significant degree of judgment.
The fair value of an equity investment in a publicly traded company is based upon the closing public share price on the date of measurement. These assets are recorded at fair value on a recurring basis.
Investment Valuation
The above-described valuation methodologies involve a significant degree of judgment. There is no single standard for determining the estimated fair value of investments that do not have an active observable market. Valuations of privately held investments are inherently uncertain, as they are based on estimates, and their values may fluctuate over time. The determination of fair value may differ materially from the values that would have been used if an active market for these investments existed. In some cases, the fair value of such investments is best expressed as a range of values derived utilizing different methodologies from which a single estimate may then be determined.
Investments measured at fair value on a recurring basis are categorized in the table below based upon the lowest level of significant input to the valuations as of September 30, 2022 and December 31, 2021. The Company transfers investments in and out of Levels 1, 2 and 3 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.

Credit Loss, Financial Instrument
Note 5. Credit Risk
Debt investments may be affected by business, financial market or legal uncertainties. Prices of investments may be volatile, and a variety of factors that are inherently difficult to predict, such as domestic, economic and political developments, may significantly affect the value of these investments. In addition, the value of these investments may fluctuate as the general level of interest rates fluctuates.
In many instances, the portfolio company’s ability to repay the debt investments is dependent on additional funding by its venture capital investors, a future sale or an initial public offering. The value of these investments may be detrimentally affected to the extent a borrower defaults on its obligations, there is insufficient collateral and/or there are extensive legal and other costs incurred in collecting on a defaulted loan.

Credit Facility
In February 2014, the Company, along with its Financing Subsidiary as borrower, entered into a credit agreement with Deutsche Bank AG, New York Branch acting as administrative agent and the other lenders party thereto, which provided the Company with a $150.0 million commitment, subject to borrowing base requirements (as amended and restated from time to time, the “Credit Facility”). As of September 30, 2022, the Company had $350 million in total commitments available under the Credit Facility, which includes an accordion feature that allows the Company to increase the size of the Credit Facility to up to $400 million under certain circumstances. On July 22, 2022, the Credit Facility was amended to, among other things, extend the revolving period from November 30, 2022 to May 31, 2024 and the scheduled maturity date from May 31, 2024 to November 30, 2025 (unless otherwise terminated earlier pursuant to its terms), as well as change the floating rate from LIBOR to SOFR.
Borrowings under the Credit Facility bear interest at the sum of (i) a floating rate based on certain indices, including SOFR and commercial paper rates (subject to a floor of 0.50%), plus (ii) a margin of 2.80% if facility utilization is greater than or equal to 75%, 2.90% if utilization is greater than or equal to 50%, 3.00% if utilization is less than 50% and 4.5% during the amortization period. Borrowings under the Credit Facility are secured only by the assets of the Financing Subsidiary. The Company agreed to pay Deutsche Bank AG a syndication fee and to pay to Deutsche Bank AG a fee to act as administrative agent under the Credit Facility as well as to pay each lender (i) a commitment fee based on each lender’s commitment and (ii) a fee of 0.50% per annum for any unused borrowings under the Credit Facility on a monthly basis. The Credit Facility contains affirmative and restrictive covenants including, but not limited to, an advance rate limitation of 50.0% of the applicable balance of net assets held by the Financing Subsidiary, maintenance of minimum net worth, a ratio of total assets to total indebtedness of not less than the greater of 3:2 and the amount so required under the 1940 Act, a key man clause relating to the Company’s Chief Executive Officer, James P. Labe, and the Company’s President and Chief Investment Officer, Sajal K. Srivastava, and eligibility requirements, including but not limited to geographic and industry concentration limitations and certain loan grade classifications. Furthermore, events of default under the Credit Facility include, among other things, (i) a payment default; (ii) a change of control; (iii) bankruptcy; (iv) a covenant default; and (v) failure by the Company to maintain its qualification as a BDC under the 1940 Act. As of September 30, 2022 and December 31, 2021, the Company was in compliance with all covenants under the Credit Facility.
As of September 30, 2022 and December 31, 2021, the Company had outstanding borrowings under the Credit Facility of $121.0 million and $200.0 million, respectively, excluding deferred credit facility costs of $4.5 million and $2.2 million, respectively, which is included in the Company’s consolidated statements of assets and liabilities. The book value of the Credit Facility approximates fair value due to the relatively short maturity, cash repayments and market interest rates of the instrument. The fair value of the Credit Facility would be categorized as Level 3 of the fair value hierarchy if determined as of the reporting date.
During the three and nine months ended September 30, 2022, the Company had average outstanding borrowings under the Credit Facility of $104.2 million and $76.7 million, respectively, at a weighted average interest rate, inclusive of unused fees, of 6.29% and 5.28%, respectively.
During the three and nine months ended September 30, 2021, the Company had average outstanding borrowings under the Credit Facility of $13.6 million and $27.9 million, respectively, at a weighted average interest rate, inclusive of unused fees, of 4.04% and 3.87%, respectively.
As of September 30, 2022 and December 31, 2021, $387.8 million and $485.5 million, respectively, of the Company’s assets, including restricted cash, were pledged for borrowings under the Credit Facility, leaving $595.8 million and $442.2 million of assets unencumbered, respectively.
2022 Notes
On July 14, 2017, the Company completed a public offering of $65.0 million in aggregate principal amount of its 5.75% notes due 2022 (the “2022 Notes”) and received net proceeds of $62.8 million after the payment of fees and offering costs. On July 24, 2017, as a result of the underwriters’ full exercise of their option to purchase additional 2022 Notes, the Company issued an additional $9.75 million in aggregate principal amount of the 2022 Notes and received net proceeds of $9.5 million after the payment of fees and offering costs. The interest on the 2022 Notes accrued at an annual rate of 5.75%, payable quarterly.
On March 5, 2021, the Company notified the trustee under the indenture governing the 2022 Notes of the Company’s election to redeem, in full, the $74.75 million aggregate principal amount of the 2022 Notes outstanding, and instructed the trustee to provide notice of such redemption to the holders of the 2022 Notes in accordance with the terms of the indenture. On April 5, 2021 (the “Redemption Date”), the Company redeemed the outstanding 2022 Notes in full in accordance with the terms of the governing indenture. As of the Redemption Date, the outstanding 2022 Notes had an aggregate principal amount of $74.75 million and accrued but unpaid interest of approximately $1.0 million. The 2022 Notes were delisted on the NYSE effective as of the Redemption Date. The redemption was accounted for as a debt extinguishment in accordance with ASC 470-50, Modifications and Extinguishments, which resulted in a realized loss of $0.7 million.
2025 Notes
On March 19, 2020, the Company completed a private debt offering of $70.0 million in aggregate principal amount of its 4.50% unsecured notes due March 19, 2025 (the “2025 Notes”) in reliance on Section 4(a)(2) of the Securities Act. The interest on the 2025 Notes is payable semiannually on March 19 and September 19 each year.
The 2025 Notes may be redeemed in whole or in part at any time or from time to time at the Company’s option at par plus accrued interest to the prepayment date and, if applicable, a make-whole premium. In addition, the Company is obligated to offer to prepay the 2025 Notes at par plus accrued and unpaid interest up to, but excluding, the date of prepayment, if certain change in control events occur. The 2025 Notes are general unsecured obligations of the Company that rank pari passu with all outstanding and future unsecured unsubordinated indebtedness issued by the Company; provided, however, in the event that the Company creates, incurs, assumes or permits to exist liens on or with respect to any of its property or assets in connection with future secured indebtedness of more than an aggregate principal amount of $25 million, the 2025 Notes will generally become secured concurrently therewith, equally and ratably with such indebtedness.
The Master Note Purchase Agreement (the “Note Purchase Agreement”) under which the 2025 Notes were issued contains customary terms and conditions for unsecured notes issued in a private placement, including, without limitation, affirmative and negative covenants such as information reporting, maintenance of the Company’s status as a BDC within the meaning of the 1940 Act, a minimum asset coverage ratio of 1.50 to 1.00, a minimum interest coverage ratio of 1.25 to 1.00, and minimum stockholders’ equity of $216,129,000, as adjusted upward by an amount equal to 65% of the net proceeds from the issuance of shares of the Company’s common stock subsequent to December 31, 2019. In addition, in the event that a Below Investment Grade Event (as defined in the Note Purchase Agreement) occurs, the 2025 Notes will bear interest at a fixed rate of 5.50% per year from the date of the occurrence of the Below Investment Grade Event to and until the date on which the Below Investment Grade Event is no longer continuing.
The Note Purchase Agreement also contains customary events of default with customary cure and notice periods, including, without limitation, nonpayment, incorrect representation in any material respect, breach of covenant, cross-default under other indebtedness of the Company or subsidiary guarantors, certain judgments and orders, certain events of bankruptcy, and breach of a key man clause relating to the Company’s Chief Executive Officer, James P. Labe, and the Company’s President and Chief Investment Officer, Sajal K. Srivastava. As of September 30, 2022 and December 31, 2021, the Company was in compliance with all covenants under the 2025 Notes.
The 2025 Notes are recorded at amortized cost in the consolidated statements of assets and liabilities. Amortized cost includes $0.5 million of deferred issuance cost as of September 30, 2022, which is amortized and expensed over the five-year term of the 2025 Notes based on an effective yield method. The book value of the 2025 Notes approximates fair value and would be categorized as Level 3 of the fair value hierarchy if determined as of the reporting date.
2026 Notes
On March 1, 2021, the Company completed a private debt offering of $200.0 million in aggregate principal amount of its 4.50% unsecured notes due March 1, 2026 (the “2026 Notes”) in reliance on Section 4(a)(2) of the Securities Act. The interest on the 2026 Notes is payable semiannually on March 19 and September 19 each year, beginning on September 19, 2021.
The 2026 Notes are governed by the terms of the First Supplement, dated as of March 1, 2021 (the “First Supplement”), to the Note Purchase Agreement. The 2026 Notes may be redeemed in whole or in part at any time or from time to time at the Company’s option at par plus accrued interest to the prepayment date and, if applicable, a make-whole premium. In addition, the Company is obligated to offer to prepay the 2026 Notes at par plus accrued and unpaid interest up to, but excluding, the date of prepayment, if certain change in control events occur. The 2026 Notes are general unsecured obligations of the Company that rank pari passu with all outstanding and future unsecured unsubordinated indebtedness issued by the Company; provided, however, in the event that the Company creates, incurs, assumes or permits to exist liens on or with respect to any of its property or assets in connection with future secured indebtedness of more than an aggregate principal amount of $25 million, the 2026 Notes will generally become secured concurrently therewith, equally and ratably with such indebtedness. In addition, in the event that a Below Investment Grade Event (as defined in the Note Purchase Agreement) occurs, the 2026 Notes will bear interest at a fixed rate of 5.50% per year from the date of the occurrence of the Below Investment Grade Event to and until the date on which the Below Investment Grade Event is no longer continuing. The other terms and conditions applicable to the 2026 Notes under the Note Purchase Agreement, as modified by the First Supplement, including events of default and affirmative and negative covenants, are substantially similar to the terms and conditions applicable to the 2025 Notes. As of September 30, 2022 and December 31, 2021, the Company was in compliance with all covenants under the 2026 Notes.
The 2026 Notes are recorded at amortized cost in the consolidated statements of assets and liabilities. Amortized cost includes $1.5 million of deferred issuance cost as of September 30, 2022, which is amortized and expensed over the five-year term of the 2026 Notes based on an effective yield method. The book value of the 2026 Notes approximates fair value and would be categorized as Level 3 of the fair value hierarchy if determined as of the reporting date.
2027 Notes
On February 28, 2022, the Company completed a private debt offering of $125.0 million in aggregate principal amount of its 5.00% unsecured notes due February 28, 2027 (the “2027 Notes”) in reliance on Section 4(a)(2) of the Securities Act. The interest on the 2027 Notes is payable semiannually on February 28 and August 28 each year, beginning on August 28, 2022.
The 2027 Notes are governed by the terms of the Second Supplement, dated as of February 28, 2022 (the “Second Supplement”), to the Note Purchase Agreement. The 2027 Notes may be redeemed in whole or in part at any time or from time to time at the Company’s option at par plus accrued interest to the prepayment date and, if applicable, a make-whole premium. In addition, the Company is obligated to offer to prepay the 2027 Notes at par plus accrued and unpaid interest up to, but excluding, the date of prepayment, if certain change in control events occur. The 2027 Notes are general unsecured obligations of the Company that rank pari passu with all outstanding and future unsecured unsubordinated indebtedness issued by the Company; provided, however, in the event that the Company creates, incurs, assumes or permits to exist liens on or with respect to any of its property or assets in connection with future secured indebtedness of more than an aggregate principal amount of $25 million, the 2027 Notes will generally become secured concurrently therewith, equally and ratably with such indebtedness. In addition, in the event that a Below Investment Grade Event (as defined in the Note Purchase Agreement) occurs, the 2027 Notes will bear interest at a fixed rate of 6.00% per year from the date of the occurrence of the Below Investment Grade Event to and until the date on which the Below Investment Grade Event is no longer continuing. The other terms and conditions applicable to the 2027 Notes under the Note Purchase Agreement, as modified by the Second Supplement, including events of default and affirmative and negative covenants, are substantially similar to the terms and conditions applicable to the 2025 Notes and the 2026 Notes. As of September 30, 2022, the Company was in compliance with all covenants under the 2027 Notes.
The 2027 Notes are recorded at amortized cost in the consolidated statements of assets and liabilities. Amortized cost includes $1.2 million of deferred issuance cost as of September 30, 2022, which is amortized and expensed over the five-year term of the 2027 Notes based on an effective yield method. The book value of the 2027 Notes approximates fair value and would be categorized as Level 3 of the fair value hierarchy if determined as of the reporting date.

Commitments
As of September 30, 2022 and December 31, 2021, the Company’s unfunded commitments totaled $331.1 million to 37 portfolio companies and $191.7 million to 22 portfolio companies, respectively, of which $128.4 million and $50.3 million, respectively, was dependent upon the portfolio companies reaching certain milestones before the debt commitment becomes available to them.
The Company’s credit agreements contain customary lending provisions that allow it relief from funding obligations for previously made commitments in instances where the underlying company experiences material adverse events that affect the financial condition or business outlook for the company. Since these commitments may expire without being drawn upon, unfunded commitments do not necessarily represent future cash requirements or future earning assets for the Company.
The following table shows the Company’s unfunded commitments by portfolio company as of September 30, 2022 and December 31, 2021:

The table above also shows the fair value of the Company’s unfunded commitment liability totaling $5.3 million and $3.2 million as of September 30, 2022 and December 31, 2021, respectively. The fair value at the inception of the delay draw credit agreements is equal to the fees and warrants received to enter into these agreements, taking into account the remaining terms of the agreements and the relevant counterparty’s credit profile. The unfunded commitment liability reflects the fair value of these future funding commitments and is included in “Other accrued expenses and liabilities” in the Company’s consolidated statements of assets and liabilities.
These liabilities are considered Level 3 liabilities under ASC Topic 820 as there is no known or accessible market or market indices for these types of financial instruments. Both observable and unobservable inputs were used to determine the fair value of positions that the Company has classified within the Level 3 category.

Equity Equity
Since inception through September 30, 2022, the Company has issued 34,999,352 shares of common stock through an initial public offering and a concurrent private placement offering in 2014, a registered follow-on offering in 2015, a private placement offering in 2017, a registered follow-on offering and concurrent private placement offering in 2018, a registered follow-on offering in 2020 and a registered follow-on offering in 2022. The Company received net proceeds from these offerings of $488.3 million, net of the portion of the underwriting sales load and offering costs paid by the Company. Included in the $488.3 million of net proceeds from these offerings is $55.3 million in net proceeds from the Company’s issuance in August 2022 of an aggregate of 4,161,807 shares of common stock in a registered follow-on offering pursuant to an underwriting agreement by and among the Company, the Adviser and the Administrator, on the one hand, and Wells Fargo Securities, LLC and Morgan Stanley & Co. LLC, as representatives of the several underwriters named in the underwriting agreement. 411,807 of the shares issued in August 2022 were issued pursuant to the underwriters’ option to purchase additional shares.
The Company has adopted a dividend reinvestment plan for its stockholders, which is an “opt out” dividend reinvestment plan. Under this plan, if the Company declares a cash distribution to stockholders, the amount of such distribution is automatically reinvested in additional shares of common stock unless a stockholder specifically “opts out” of the dividend reinvestment plan. If a stockholder opts out, that stockholder receives cash distributions.
On September 30, 2022, we entered into a sales agreement (the “Sales Agreement”) with the Adviser, the Administrator and UBS Securities LLC (the “Sales Agent”), providing for the issuance from time to time of up to an aggregate of $50 million in shares of our common stock by means of at-the-market offerings (the “ATM Program”). Subject to the terms of the Sales Agreement, the Sales Agent is not required to sell any specific number or dollar amount of securities but will act as our sales agent using commercially reasonable efforts consistent with the Sales Agent’s normal trading and sales practices, on mutually agreed terms between us and the Sales Agent.
As of September 30, 2022, $50.0 million in shares remained available for sale under the ATM Program.
In October 2017, the Company entered into a securities purchase agreement (the “Securities Purchase Agreement”) with certain accounts managed by Goldman Sachs Asset Management, L.P. (the “GSAM Purchasers”), pursuant to which the Company sold to the GSAM Purchasers an aggregate of 1,594,007 shares of the Company’s common stock in October 2017 in a private offering exempt from registration under Section 4(a)(2) of the Securities Act and Regulation D thereunder (the “October 2017 GSAM Shares”). Subsequently, in August 2018, pursuant to the terms of the Securities Purchase Agreement, the GSAM Purchasers purchased an additional 200,000 shares of the Company’s common stock in a private offering exempt from registration under Section 4(a)(2) of the Securities Act and Regulation D thereunder (the “August 2018 GSAM Shares” and, together with the October 2017 GSAM Shares, the “GSAM Shares”).
Pursuant to the terms of the Securities Purchase Agreement, the Company has granted the GSAM Purchasers certain registration rights and the related right to participate in future equity offerings conducted by the Company. Specifically, the GSAM Purchasers have the right to sell up to one-third of the total number of GSAM Shares then held by them, in the aggregate, in any underwritten offering initiated by the Company. Additionally, the GSAM Purchasers have the right at any time or from time to time to elect, in writing and pursuant to the terms of and restrictions under the Securities Purchase Agreement, to sell the GSAM Shares pursuant to an offering, including an underwritten offering or block trade, under the Company’s currently effective shelf registration statement.
The following tables show information on the proceeds raised along with any related underwriting sales load and associated offering expenses, and the price at which common stock was issued by the Company, during the nine months ended September 30, 2022 and the year ended December 31, 2021:

Note 11. Distributions
The Company has elected to be treated, and intends to comply with the requirements to continue to qualify annually, as a RIC under the Code. In order to maintain its ability to be subject to tax as a RIC, among other things, the Company is required to distribute at least 90% of its net ordinary income and net realized short-term capital gains in excess of its net realized long-term capital losses, if any, to its stockholders. Additionally, to avoid a nondeductible 4% U.S. federal excise tax on certain of the Company’s undistributed income, the Company must distribute during each calendar year an amount at least equal to the sum of: (a) 98% of the Company’s ordinary income (not taking into account any capital gains or losses) for such calendar year; (b) 98.2% of the amount by which the Company’s capital gains exceed the Company’s capital losses (adjusted for certain ordinary losses) for a one-year period ending on October 31 of the calendar year (unless an election is made by the Company to use its taxable year); and (c) certain undistributed amounts from previous years on which the Company paid no U.S. federal income tax.
For the tax years ended December 31, 2021, 2020 and 2019, the Company was subject to a 4% U.S. federal excise tax and the Company may be subject to this tax in future years. In such cases, the Company is liable for the tax only on the amount by which the Company does not meet the foregoing distribution requirement. The character of income and gains that the Company distributes is determined in accordance with income tax regulations that may differ from GAAP. Book and tax basis differences relating to stockholder dividends and distributions and other permanent book and tax differences are reclassified to paid-in capital. The Company incurred a non-deductible U.S. federal excise tax of $337,000 and $478,000 for the years ended December 31, 2021 and 2020.
The following table shows the Company's cash distributions per share that have been authorized by the Board since the Company's initial public offering to September 30, 2022. From March 5, 2014 (commencement of operations) to December 31, 2015, and during the years ended December 31, 2017 and December 31, 2018, distributions represent ordinary income as the Company's earnings exceeded distributions. Approximately $0.24 per share of the distributions during the year ended December 31, 2016 represented a return of capital. During the years ended December 31, 2021, 2020 and 2019, distributions represent ordinary income and long term capital gains.

(2)Represents a special distribution.
It is the Company’s intention to distribute all or substantially all of its taxable income earned over the course of the year. However, the Company may choose not to distribute all of its taxable income for a number of reasons, including retaining excess taxable income for investment purposes and/or to defer the payment of distributions associated with the excess taxable income for future calendar years. During the three and nine months ended September 30, 2022, the Company recorded $0.2 million and $0.5 million, respectively, for an excise tax accrual. No provision for income tax was recorded in the Company's consolidated statements of operations for the three and nine months ended September 30, 2022 and 2021. For the three and nine months ended September 30, 2022, total distributions of $0.36 per share and $1.08 per share, respectively, were declared and paid and represented distributions from ordinary income. For the three and nine months ended September 30, 2021, total distributions of $0.36 per share and $1.08 per share, respectively, were declared and paid and represented distributions from ordinary income. As of September 30, 2022, the Company estimated it had undistributed taxable earnings from net investment income (or “spillover income”) of $18.5 million, or $0.52 per share. Since March 5, 2014 (commencement of operations) to September 30, 2022, total distributions of $12.58 per share have been paid.

Except as noted below, the following annualized percentages were calculated based on actual expenses incurred in the nine months ended September 30, 2022 and net assets as of September 30, 2022, and do not include events occurring subsequent thereto. The table and examples below include all fees and expenses of our consolidated subsidiaries.
Stockholder Transaction Expenses:
Sales load payable by us (as a percentage of offering price)2.00 %(1)
Offering expenses (as a percentage of offering price)0.50 %(2)
Dividend reinvestment plan expenses— %(3)
Total Stockholder Transaction Expenses (as a percentage of offering price)2.50 %
Annual Expenses (as percentage of net assets attributable to common stock):
Base management fee payable under the Investment Advisory Agreement3.45 %(4)
Incentive fee payable under the Investment Advisory Agreement (20% of net investment income and realized capital gains)1.99 %(5)
Interest payments on borrowed funds5.49 %(6)
Other expenses1.44 %(7)
Total annual expenses12.37 %
__________

(1)     The maximum agent commission with respect to the shares of our common stock sold under the ATM Program is 2.00%. In the event that our securities are sold to or through underwriters, a corresponding prospectus or prospectus supplement will disclose the applicable sales load.
(2)    The percentage reflects estimated offering expenses of approximately $250,000 payable by us for the estimated duration of the ATM Program and assumes we sell all $50.0 million of common stock initially available for sale under the ATM Program.
(3) The expenses of the dividend reinvestment plan are included in “Other expenses.” The plan administrator’s fees will be paid by us. We will not charge any brokerage charges or other charges to stockholders who participate in the plan. However, your own broker may impose brokerage charges in connection with your participation in the plan.
(4) Our base management fee, payable quarterly in arrears, is calculated at an annual rate of 1.75% of our average adjusted gross assets, including assets purchased with borrowed amounts and other forms of leverage. See “Business-Management Agreements-Investment Advisory Agreement” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021 for more information.
(5) Assumes that annual incentive fees earned by our Adviser remain consistent with the incentive fees that would have been earned by our Adviser (if not for the cumulative “catch-up” provision explained below) for the nine months ended September 30, 2022 adjusted for any equity issuances. The incentive fee consists of two components, investment income and capital gains, which are largely independent of each other, with the result that one component may be payable even if the other is not payable. Under the investment income component, we pay our Adviser each quarter 20.0% of the amount by which our pre-incentive fee net investment income for the quarter exceeds a hurdle rate of 2.0% (which is 8.0% annualized) of our net assets at the end of the immediately preceding calendar quarter, subject to a “catch-up” provision pursuant to which our Adviser receives all of such income in excess of the 2.0% level but less than 2.5% and subject to a total return requirement. The effect of the “catch-up” provision is that, subject to the total return provision discussed below, if pre-incentive fee net investment income exceeds 2.5% in any calendar quarter, our Adviser receives 20.0% of our pre-incentive fee net investment income as if the 2.0% hurdle rate did not apply. The foregoing incentive fee is subject to a total return requirement, which provides that no incentive fee in respect of our pre-incentive fee net investment income is payable except to the extent that 20.0% of the cumulative net increase in net assets resulting from operations since March 5, 2014 exceeds the cumulative incentive fees accrued and/or paid since March 5, 2014. In other words, any investment income incentive fee that is payable in a calendar quarter will be limited to the lesser of (i) 20.0% of the amount by which our pre-incentive fee net investment income for such calendar quarter exceeds the 2.0% hurdle rate, subject to the “catch-up” provision and (ii) (x) 20.0% of the cumulative net increase in net assets resulting from operations since March 5, 2014 minus (y) the cumulative incentive fees accrued and/or paid since March 5, 2014. For the foregoing purpose, the “cumulative net increase in net assets resulting from operations” is the sum of our pre-incentive fee net investment income, realized gains and losses and unrealized appreciation and depreciation since March 5, 2014. Under the capital gains component of the incentive fee, we pay our Adviser at the end of each calendar year 20.0% of our aggregate cumulative realized capital gains from inception through the end of that year, computed net of our aggregate cumulative realized capital losses and our aggregate cumulative unrealized depreciation through the end of such year, less the aggregate amount of any previously paid capital gain incentive fees. For the foregoing purpose, our “aggregate cumulative realized capital gains” does not include any unrealized appreciation. It should be noted that we accrue an incentive fee for accounting purposes taking into account any unrealized appreciation in accordance with GAAP. The capital gains component of the incentive fee is not subject to any minimum return to stockholders.
(6) “Interest payments on borrowed funds” represent our estimated annual interest payment, fees and credit facility expenses and are based on results of operations for the nine months ended September 30, 2022 (annualized), including with respect to the Credit Facility, the 2025 Notes, the 2026 Notes, and the 2027 Notes. The costs associated with any outstanding indebtedness are indirectly borne by our common stockholders. The amount of leverage we employ at any particular time will depend on, among other things, the Board and our Adviser’s assessment of the market and other factors at the time at any proposed borrowing. We may also issue preferred stock, subject to our compliance with applicable requirements under the 1940 Act.
(7) “Other expenses” (approximately $6.5 million) represent our estimated amounts for the current fiscal year, which are based upon the results of our operations for the nine months ended September 30, 2022, including payments under the Administration Agreement based on our allocable portion of overhead and other expenses incurred by our Administrator.

The effect of the “catch-up” provision is that, subject to the total return provision discussed below, if pre-incentive fee net investment income exceeds 2.5% in any calendar quarter, our Adviser receives 20.0% of our pre-incentive fee net investment income as if the 2.0% hurdle rate did not apply.

General Description of Registrant [Abstract]                          
Risk Factors [Table Text Block]                         Risk Factors
You should carefully consider the risks referenced below and all other information contained in this Quarterly Report on Form 10-Q, including our interim financial statements and the related notes thereto, before making a decision to purchase our securities. Any such risks and uncertainties are not the only ones facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may have a material adverse effect on our business, financial condition and/or operating results, as well as the market price of our securities.
In addition to the other information set forth in this report, you should carefully consider the risk factors previously disclosed in our Annual Report on Form 10‑K for the year ended December 31, 2021 that we filed with the SEC on March 2, 2022, which could materially affect our business, financial condition or operating results.

Inflation has adversely affected and may continue to adversely affect the business, results of operations and financial condition of our portfolio companies.

Certain of our portfolio companies are in industries that have been impacted by inflation. Recent inflationary pressures have increased the costs of labor, energy and raw materials and have adversely affected consumer spending, economic growth and our portfolio companies’ operations. If such portfolio companies are unable to pass any increases in their costs of operations along to their customers, it could adversely affect their operating results and impact their ability to pay interest and principal on our loans, particularly if interest rates rise in response to inflation. In addition, any projected future decreases in our portfolio companies’ operating results due to inflation could adversely impact the fair value of those investments. Any decreases in the fair value of our investments could result in future realized or unrealized losses and therefore reduce our net assets resulting from operations. Additionally, the Federal Reserve has raised, and has indicated its intent to continue raising, certain benchmark interest rates in an effort to combat inflation.
Share Price [Table Text Block]

The accompanying interim consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Articles 6, 10 and 12 of Regulation S-X. Accordingly, certain disclosures required by GAAP for the annual reporting of consolidated financial statements are omitted.
