(1)      The market values for securities are determined as follows: Equity securities traded on a national securities exchange or traded over-the-counter and quoted on the NASDAQ System are valued at last sales prices. Fixed income securities and any other securities for which it is determined that market prices are unavailable or inappropriate are valued at a fair value using a procedure determined in good faith by the Board of Directors which includes the use of a pricing service. Each money market instrument having a maturity of 60 days or less is valued on an amortized cost basis, which approximates market value.
