During the third quarter of fiscal year 2014, we sold all of our remaining ARS for $26.2 million and received the proceeds during the quarter. The previously recorded unrealized losses associated with our ARS have been adjusted based on the sale prices and recorded as a realized loss of $2.6 million during fiscal year 2014 within interest income and other in the consolidated statement of operations.

During prior periods in which we held ARS, we evaluated the risks related to the structure, collateral and liquidity of the investment and forecasted the probability of issuer default, auction failure and a successful auction at par or a redemption at par for each future auction period. The weighted average cash flow for each period was then discounted back to present value for each security. Based on this methodology, we determined that the fair value of our ARS investments was $24.8 million at November 30, 2013. The temporary impairment recorded in accumulated other comprehensive loss to reduce the value of our available-for-sale ARS investments was $4.0 million at November 30, 2013. As we determined that these investments lacked short-term liquidity as of November 30, 2013, they were classified as long-term investments on the consolidated balance sheets at November 30, 2013.

During the fourth quarter of fiscal year 2013, the exit bankruptcy plan for an issuer of one of our ARS, which was in default and on whose behalf the underlying bond insurer was making interest payments, was approved by a federal bankruptcy judge in federal court. The exit bankruptcy plan included a settlement provision with the holders of the ARS, which were given the option to receive 80% of the par value of their holdings, but renounce their claim with the bond issuer, or receive 65% of the par value of their holdings and retain their insurance rights. We accepted the 80% settlement offer and as a result we adjusted the fair value of this ARS to the amount of the settlement as of November 30, 2013. The previously recorded unrealized loss associated with this ARS has been recorded as a realized loss in fiscal year 2013 due to the settlement, which we received in December 2013. The realized loss of $0.4 million is recorded in interest income and other on the statement of operations for the fiscal year ended November 30, 2013. As this investment no longer lacked short-term liquidity, it was classified as a short-term investment on our consolidated balance sheet at November 30, 2013.
