Proceeds from the sales and maturities of available-for-sale securities were $109,357 and $213,930 for the six months ended July 31, 2016 and 2015, respectively. The Company included in “Other income (expense), net,” in the Condensed Consolidated Statements of Income, net realized gains of $9 and $22 for the three and six months ended July 31, 2016, respectively, and net realized gains of $39 and $42 for the three and six months ended July 31, 2015, respectively. Amortization of discounts and premiums, net, resulted in a reduction of “Other income (expense), net” of $567 and $1,161 for the three and six months ended July 31, 2016, and $1,042 and $2,158 for the three and six months ended July 31, 2015, respectively. Mutual funds represent assets held in an irrevocable rabbi trust for the Company’s Non-qualified Deferred Compensation Plan (“NQDC”). These assets are a source of funds to match the funding obligations to participants in the NQDC but are subject to the Company’s general creditors. The Company elected the fair value option for financial assets for the mutual funds held in the rabbi trust resulting in all unrealized gains and losses being recorded in “Other income (expense), net” in the Condensed Consolidated Statements of Income.
