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).
