Marketable Securities

The Company invests in marketable securities that are classified as available-for-sale and records them at fair value in the Company's unaudited consolidated balance sheets. Marketable securities reported as current assets represent investments that mature within one year from the balance sheet date. Long-term marketable securities represent investments with maturity dates greater than one year from the balance sheet date.

Unrealized gains and losses are excluded from earnings and reported as a separate component of accumulated other comprehensive income until the security is sold or matures. Gains or losses realized from sales of marketable securities are computed based on the specific identification method and recognized as a component of "Other (loss) income, net" in the accompanying unaudited consolidated statements of operations. During the three months ended March 31, 2016, the Company sold marketable securities with a fair value and amortized cost of $3.5 million and recognized gross losses of approximately $17,000 on sale of marketable securities. The Company collected cash proceeds of $3.5 million from the sale of marketable securities and reclassified unrealized net holding losses of approximately $17,000 on the marketable securities from accumulated other comprehensive income into "Other (loss) income, net" in the accompanying unaudited consolidated statements of operations as a result of these transactions. During the six months ended March 31, 2016, the Company sold marketable securities with a fair value of $127.6 million and amortized cost of $127.7 million and recognized gross losses of approximately $158,000 and gross gains of approximately $3,000 on sale of marketable securities. The Company collected cash proceeds of $127.0 million from the sale of marketable securities and reclassified unrealized net holding losses of approximately $155,000 on the marketable securities from accumulated other comprehensive income into "Other (loss) income, net" in the accompanying unaudited consolidated statements of operations as a result of these transactions. There were no sales of marketable securities during the three and six months ended March 31, 2015.

There were no unrealized gains or losses on available for sale securities presented as a component of accumulated other comprehensive income as of March 31, 2016. Unrealized gains on available for sale securities presented as a component of accumulated other comprehensive income were approximately $102,300 at September 30, 2015. Net unrealized holding gains on available for sale securities recorded as a component of other comprehensive income (loss) before the impact of reclassifications were approximately $22,000 and $202,000, respectively, during the six months ended March 31, 2016 and 2015.

The fair values of the marketable securities by contractual maturities at March 31, 2016 are presented below (in thousands):



	Fair Value
Due in one year or less	$	66
Due after one year through five years	3,776
Due after ten years	2,283
Total marketable securities	$	6,125

Expected maturities could differ from contractual maturities because the security issuers may have the right to prepay obligations without prepayment penalties.

The Company reviews the marketable securities for impairment at each reporting period to determine if any of the securities have experienced an other-than-temporary decline in fair value. The Company considers factors, such as the length of time and extent to which the market value has been less than the cost, the financial condition and near-term prospects of the issuer, the Company's intent to sell, or whether it is more likely than not it will be required to sell the investment before recovery of its amortized cost basis. If the Company believes that an other-than-temporary decline in fair value has occurred, it writes down the investment to fair value and recognizes the credit loss in earnings and the non-credit loss in accumulated other comprehensive income. As of March 31, 2016 and September 30, 2015, fair value of the marketable securities in unrealized loss position was $2.0 million and $40.4 million, respectively. These securities were not considered other-than-temporarily impaired and, as such, the Company did not recognize impairment losses during the periods then ended. The unrealized losses are attributable to changes in interest rates which impact the value of the investments.
