The estimated fair value of our short-term, long-term, and available-for-sale investments approximates their cost. Interest income is accrued as earned. Dividend income is recognized as income on the date the security trades “ex-dividend.” The cost of marketable securities sold is determined by the specific identification method. Realized gains or losses are reflected in income and were not material in each of the periods presented.
