As of June 30, 2012, 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. 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 that are being accounted for as held-to-maturity securities, and the related gross unrealized gains and losses, were as follows as of June 30, 2012 ( in thousands):

			Gross Unrealized
	Cost		Gains		Losses		Fair Value
Short-term Investments:
Corporate bonds	$	17,377	$	86	$	-	$	17,463
Long-term Investments
Corporate bonds	$	27,665	$	133	$	210	$	27,588

At June 30, 2012, the length of time until maturity of these securities ranged from two to 34 months.
