The table above, which shows the gross unrealized gains and (losses) aggregated by investment category for available-for-sale investments as of December 31, 2014, reflects the inclusion of investments with contractual maturities greater than one year from the date of purchase within short-term investments. Management has the ability, if necessary, to liquidate any of its investments in order to meet the Company’s liquidity needs in the next 12 months. Accordingly, those investments with contractual maturities greater than one year from the date of purchase are classified as short-term on the accompanying balance sheets. Interest income is accrued as earned. Dividend income is recognized as income on the date the stock trades “ex-dividend.” The cost of marketable securities sold is determined by the specific identification method and realized gains or losses are reflected in income and was not material in 2015, 2014 and 2013.
