[1] Per share data are based on shares outstanding and results are rounded.
[2] All of the Corporation’s portfolio assets are pledged as collateral for purposes of securing the Corporation’s senior secured revolving credit facility pursuant to a general security agreement, dated June 27, 2022, between the Corporation, the subsidiaries listed therein, and the Lender (as defined herein).
[3] Non-Control/Non-Affiliate Investments are investments that are neither Control Investments nor Affiliate Investments.
[4] The Date Acquired column indicates the date on which the Corporation first acquired an investment.
[5] These investments are non-income producing. All other investments are income producing. Non-income producing investments have not generated cash payments of interest or dividends including LLC tax-related distributions within the last twelve months or are not expected to do so going forward. If a debt or a preferred equity investment fails to make its most recent payment, then the investment will also be classified as non-income producing.
[6] Each equity percentage estimates the Corporation’s ownership interest in the applicable portfolio investment. The estimated ownership is calculated based on the percent of outstanding voting securities held by the Corporation or the potential percentage of voting securities held by the Corporation upon exercise of warrants or conversion of debentures, or other available data. If applicable, the symbol “<1%” indicates that the Corporation holds an equity interest of less than one percent.
[7] As of December 31, 2023, the total cost of investment securities was approximately $68.4 million. Net unrealized appreciation was approximately $8.8 million, which was comprised of $14.1 million of unrealized appreciation of investment securities and ($5.4) million of unrealized depreciation of investment securities. At December 31, 2023, the aggregate gross unrealized gain for federal income tax purposes was $14.1 million and the aggregate gross unrealized loss for federal income tax purposes was ($4.2) million. The net unrealized gain for federal income tax purposes was $9.9 million based on a tax cost of $68 million.
[8] The Corporation’s investments are carried at fair value in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 820 “Fair Value Measurements and Disclosures,” which defines fair value and establishes guidelines for measuring fair value. At December 31, 2023, ASC 820 designates 91% of the Corporation’s investments as “Level 3” assets. Under the valuation policy of the Corporation, unrestricted publicly traded securities are valued at the closing price for these securities on the last trading day of the reporting period. Restricted securities are subject to restrictions on resale and are valued at fair value as determined in good faith by our external investment advisor Rand Capital Management, LLC (“RCM”) and approved by the Board of Directors. Fair value is considered to be the amount that the Corporation may reasonably expect to receive for portfolio securities when sold on the valuation date. Valuations as of any particular date, however, are not necessarily indicative of amounts which may ultimately be realized as a result of future sales or other dispositions of securities and these favorable or unfavorable differences could be material. Among the factors considered in determining the fair value of restricted securities are the financial condition and operating results, projected operations, and other analytical data relating to the investment. Also considered are the market prices for unrestricted securities of the same class (if applicable) and other matters which may have an impact on the value of the portfolio company (see Note 2. “Investments” to the Consolidated Financial Statements).
[9] At December 31, 2023, restricted securities represented 91% of the fair value of the investment portfolio. Restricted securities are subject to one or more restrictions on resale and are not freely marketable. Type of investment for equity position is in the form of shares unless otherwise noted as units or interests, i.e., preferred shares, common shares.

Net unrealized appreciation was approximately $2.7 million, which was comprised of $10.8 million of unrealized appreciation of investment securities and ($8.1) million of unrealized depreciation of investment securities.

[23] The Corporation’s investments are carried at fair value in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 820 “Fair Value Measurements and Disclosures,” which defines fair value and establishes guidelines for measuring fair value. At December 31, 2024, ASC 820 designates 100% of the Corporation’s investments as “Level 3” assets. Under the valuation policy of the Corporation, unrestricted publicly traded securities are valued at the closing price for these securities on the last trading day of the reporting period. Restricted securities are subject to restrictions on resale and are valued at fair value as determined in good faith by our external investment advisor Rand Capital Management, LLC (“RCM”) and approved by the Board of Directors. Fair value is considered to be the amount that the Corporation may reasonably expect to receive for portfolio securities when sold on the valuation date. Valuations as of any particular date, however, are not necessarily indicative of amounts which may ultimately be realized as a result of future sales or other dispositions of securities and these favorable or unfavorable differences could be material. Among the factors considered in determining the fair value of restricted securities are the financial condition and operating results, projected operations, and other analytical data relating to the investment. Also considered are the market prices for unrestricted securities of the same class (if applicable) and other matters which may have an impact on the value of the portfolio company (see Note 3. “Investments” to the Consolidated Financial Statements).
[24] The Date Acquired column indicates the date on which the Corporation first acquired an investment.

The estimated ownership is calculated based on the percent of outstanding voting securities held by the Corporation or the potential percentage of voting securities held by the Corporation upon exercise of warrants or conversion of debentures, or other available data. If applicable, the symbol “<1%” indicates that the Corporation holds an equity interest of less than one percent.
[26] At December 31, 2024, restricted securities represented 100% of the fair value of the investment portfolio. Restricted securities are subject to one or more restrictions on resale and are not freely marketable. Type of investment for equity position is in the form of shares unless otherwise noted as units or interests, i.e., preferred shares, common shares.
[27] Indicates assets that the Corporation believes do not represent “qualifying assets” under Section 55(a) of the 1940 Act. Qualifying assets must represent at least 70% of the Corporation’s total assets at the time of acquisition of any additional non-qualifying assets. Of the Corporation’s total assets, 5.38% were non-qualifying assets as of December 31, 2023.

Non-income producing investments have not generated cash payments of interest or dividends including LLC tax-related distributions within the last twelve months or are not expected to do so going forward. If a debt or a preferred equity investment fails to make its most recent payment, then the investment will also be classified as non-income producing.
