5.	Investments

Investments consist principally of U.S. government and government agency obligations, mortgage-backed securities and corporate and municipal debt securities and are classified as available-for-sale at March 31, 2015 and September 30, 2014. Available-for-sale securities are reported at fair value with unrealized gains and losses, net of tax, excluded from the condensed consolidated statements of income and reported in the condensed consolidated statements of comprehensive income as well as a separate component of stockholders’ equity in the condensed consolidated balance sheets, except for other-than-temporary impairments, which are reported as a charge to current earnings. A loss would be recognized when there is an other-than-temporary impairment in the fair value of any individual security classified as available-for-sale, with the associated net unrealized loss reclassified out of accumulated other comprehensive income with a corresponding adjustment to other income. This adjustment results in a new cost basis for the investment. Interest earned on debt securities, including amortization of premiums and accretion of discounts, is included in other income. Realized gains and losses from the sales of debt securities, which are included in other income, are determined using the specific identification method.

The amortized cost, unrealized holding gains and losses, and fair value of available-for-sale securities as of March 31, 2015 and September 30, 2014 were as follows:

As of September 30, 2014, the Company concluded that the unrealized losses related to the available-for-sale securities shown above were not other-than-temporary as the Company did not have the intent to sell, nor was it more likely than not that the Company would be required to sell, before recovery of their amortized cost. As of March 31, 2015 all available-for-sale debt securities were classified as current assets as the Company plans to liquidate its investment portfolio in the third quarter of fiscal 2015 to support corporate development initiatives. Unrealized losses as of March 31, 2015 were immaterial to the Company’s consolidated financial statements.

The amortized cost and fair value of available-for-sale debt securities, by contractual maturity, at March 31, 2015 were as follows:


*(Dollars in thousands)*	Amortized Cost		Fair Value
Debt securities due within:
One year	$	3,213	$	3,221
