Realized and unrealized gains and losses on short-term investments were not material for the three and six months ended October 31, 2015 and 2014. An impairment charge is recorded in the consolidated statements of operations for declines in fair value below the cost of an individual investment that are deemed to be other-than-temporary. The Company assesses whether a decline in value is temporary based on the length of time that the fair market value has been below cost, the severity of the decline, as well as the intent and ability to hold, or plans to sell, the investment. There have been no impairment charges recognized related to short-term investments for the three and six months ended October 31, 2015 and 2014.

Contractual maturities of available-for-sale securities at October 31, 2015, are as follows (in thousands):

	Estimated Fair Value
Due in one year or less	$	43,496
Due in 1-2 years	8,446
Total Investments in debt securities	$	51,942

Actual maturities may differ from contractual maturities because some borrowers have the right to call or prepay obligations with or without call or prepayment penalties. We may sell these securities at any time for use in current operations or for other purposes, such as consideration for acquisitions, even if they have not yet reached maturity. As a result, we classify our investments, including securities with maturities beyond twelve months as current assets in the accompanying condensed consolidated balance sheets.

The Company measures certain assets, including property and equipment, goodwill and intangible assets, at fair value on a non-recurring basis. These assets are recognized at fair value when they are deemed to be impaired. The Company evaluates transfers between levels at the end of the fiscal year and assumes that any identified transfers are deemed to have occurred at the end of the reporting year. There were no transfers between levels in any of the periods presented.
