5. Investments

Investments consist principally of corporate debt securities and are classified as available-for-sale as of June 30, 2016. 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 June 30, 2016 were as follows:

	June 30, 2016
(Dollars in thousands)	Amortized Cost		Unrealized Gains		Unrealized Losses			Fair Value
Corporate bonds	$	9,562	$	1	$	(40	)	$	9,523
Total	$	9,562	$	1	$	(40	)	$	9,523

During the year ended September 30, 2015, the Company liquidated its investment portfolio to support corporate initiatives, as a result the ending balance of available-for-sale investments as of September 30, 2015 was zero.
