Investments Schedule [Abstract]

Investments

As of September 30, 2014, we held certain investments that are required to be measured for disclosure purposes at fair value on a recurring basis. These investments are considered Level 2 investments and are all considered to be held-to-maturity securities. We consider as current assets those investments which will mature in the next 12 months. The remaining investments are considered non-current assets. The amortized cost and fair value of our investments, and the related gross unrealized gains and losses, were as follows as of September 30, 2014 (in thousands):

			Gross Unrealized
	Cost		Gains		Losses			Fair Value
Short-term Investments:
Corporate bonds	$	18,178	$	36	$	--		$	18,214
Long-term Investments
Corporate bonds	$	10,000	$	--	$	(6	)	$	9,994

At September 30, 2014, the length of time until maturity of these securities ranged from one month to 57 months.
