6. OTHER LONG-TERM ASSETS

Other long-term assets consisted of the following:

	June 30, 2017		September 30, 2016

Auction rate securities (ARS)	$	5,319	$	5,494
Other long-term assets		2,505		2,620
Long-term contract asset		2,350		2,900
Other long-term investments		1,153		1,028
Total	$	11,327	$	12,042

Our ARS investments at June 30, 2017 consisted of two tax exempt municipal debt securities with a total par value of $5,319, both of which have maturities greater than ten years. The fair value of our ARS, determined using level 2 fair value inputs, was $4,877 as of June 30, 2017. We have classified our ARS as held-to-maturity based on our intention and ability to hold the securities until maturity. We believe the gross unrecognized loss of $442 is due to the illiquidity in the ARS market, rather than to credit loss. Although we believe these securities will ultimately be collected in full, we believe that it is not likely that we will be able to monetize the securities in our next business cycle (which for us is generally one year). We will continue to monitor our ARS for impairment indicators, which may require us to record an impairment charge that is deemed other-than-temporary.

In the third quarter of fiscal 2015, we amended a supply contract with an existing supplier. The amended agreement includes a fee of $4,500, which provides us the option to purchase certain raw materials beyond calendar 2016. This fee was recorded as a long-term asset at its present value and is being amortized into cost of goods sold on a straight-line basis through December 31, 2019, the expiration date of the agreement. See Note 10 for more information regarding this contract.

Other long-term assets are comprised of the long-term portion of prepaid unamortized debt costs, related to our Revolving Credit Facility, as well as miscellaneous deposits and prepayments on contracts extending beyond the next 12 months. As discussed in Note 8, we reclassified $435 of prepaid debt costs related to our Term Loan out of other long-term assets as of September 30, 2016, in accordance with the adoption of a new accounting pronouncement. As discussed in Note 3, we recorded a long-term asset and a corresponding long-term liability of $1,153 representing the fair value of our SERP investments as of June 30, 2017.
