Investments [Abstract] |
Investments | Note 4: Investments Our consolidated balance sheet at July 27, 2013, included $5.6 million of available-for-sale investments and $2.0 million of trading securities in other current assets and $32.3 million of available-for-sale investments in other long-term assets. Available-for-sale investments of $10.8 million and trading securities of $1.1 million were included in other current assets and available-for-sale investments of $29.2 million were included in other long-term assets in our consolidated balance sheet at April 27, 2013. At July 27, 2013, and April 27, 2013, $27.7 million and $29.9 million, respectively, of these investments were to enhance returns on our cash. The remaining investments were designated to fund future obligations of our non-qualified defined benefit retirement plan and our executive deferred compensation plan. All unrealized gains and losses in the tables below relate to available-for-sale investments and were included in accumulated other comprehensive loss within our consolidated statement of changes in equity because none of them were considered other-than-temporary during fiscal 2014 or fiscal 2013. If there were a decline in the fair value of an investment below its cost and the decline was considered other-than-temporary, the amount of decline below cost would be charged against earnings. The following is a summary of investments at July 27, 2013, and April 27, 2013:
