Auction Rate Securities

6. AUCTION RATE SECURITIES

At October 31, 2012, the Company held investments in auction rate securities from four different issuers having an original principal amount of $5.0 million each (aggregating $20.0 million). During the second quarter of 2013, one of the auction rate securities was redeemed by the issuer at its par value of $5.0 million. No gain or loss was recognized upon its redemption. These auction rate securities are debt instruments with stated maturities ranging from 2033 to 2050, for which the interest rate is designed to be reset through Dutch auctions approximately every 30 days. Auctions for these securities have not occurred since August 2007.

At April 30, 2013 and October 31, 2012, the estimated fair values of these securities, in total, were approximately $13.0 million and $17.8 million, respectively.

As of April 30, 2013, none of the Company’s auction rate securities were in an unrealized loss position. As of October 31, 2012, two of the Company’s auction rate securities, with an aggregate fair value of $7.8 million, were in a continuous unrealized loss position for less than twelve months and the remaining two auction rate securities, with an aggregate fair value of $10.0 million, were not in an unrealized loss position.

The following table presents the significant assumptions used to determine the fair values of the Company’s auction rate securities at April 30, 2013 and October 31, 2012:

Assumption	April 30, 2013	October 31, 2012
Discount rates	L + 0.44% - L + 3.43%	L + 1.37% - L + 6.86%
Yields	2.15%, L + 2.00%	2.15%, L + 2.00% - L + 3.50%
Average expected lives	4 - 10 years	4 - 10 years

L - One Month LIBOR

The fair values of our auction rate securities are affected most significantly by the changes in the average expected lives of the securities, but are also impacted by the specific discount rate used to adjust the outcomes to their present values. If the average expected lives of the securities increase or decrease, the fair values of the securities will decrease or increase accordingly, in amounts that will vary based on the timing of the projected cash flows and the specific discount rate used to calculate the present value of the expected cash flows.
