Marketable securities, included in other current and long-term assets, totaling $120.9 million and $14.3 million at November 30, 2012, respectively, and $106.5 million and $13.6 million at May 31, 2012, respectively, are composed of available-for-sale securities and are reported at fair value. In April 2012, we invested $22.7 million in 5.5% convertible bonds issued by Kemrock. The bonds are convertible into ordinary shares or global depositary receipts each representing one ordinary share of Kemrock stock, and may be converted at any time on or after June 4, 2012 and up to the close of business on June 12, 2017. Our investment in Kemrock convertible bonds is an available for sale security, which reflects the offsetting value of the discount on the bond as of the balance sheet date, and is classified in other long-term assets in our Consolidated Balance Sheet.

Marketable securities are composed of available-for-sale securities and are reported at fair value. Realized gains and losses on sales of investments are recognized in net income on the specific identification basis. Changes in the fair values of securities that are considered temporary are recorded as unrealized gains and losses, net of applicable taxes, in accumulated other comprehensive income (loss) within stockholders’ equity. Other-than-temporary declines in market value from original cost are reflected in operating income in the period in which the unrealized losses are deemed other than temporary. In order to determine whether other-than-temporary declines in market value have occurred, the duration of the decline in value and our ability to hold the investment are considered in conjunction with an evaluation of the strength of the underlying collateral and the extent to which the investment’s amortized cost or cost, as appropriate, exceeds its related market value.

Gross gains and losses realized on sales of investments were insignificant for the quarter ended November 30, 2012. Gross gains and losses realized on sales of investments were $1.9 million and $1.9 million, respectively, for the quarter ended November 30, 2011. During the second quarter of fiscal 2013 and 2012, we recognized losses of $0.5 million and $0.3 million, respectively, for securities deemed to have other-than-temporary impairments. These amounts are included in investment expense (income), net in the Consolidated Statements of Income.

Gross gains and losses realized on sales of investments were $5.0 million and $0.4 million, respectively, for the six months ended November 30, 2012. Gross gains and losses realized on sales of investments were $3.8 million and $4.7 million, respectively, for the six months ended November 30, 2011. During the first half of fiscal 2013 and 2012, we recognized losses of $0.6 million and $0.7 million, respectively, for securities deemed to have other-than-temporary impairments.

Summarized below are the securities we held at November 30, 2012 and May 31, 2012 that were in an unrealized loss position and that were included in accumulated other comprehensive income, aggregated by the length of time the investments had been in that position:


	November 30, 2012					May 31, 2012
(In thousands)	Fair Value		Gross Unrealized Losses			Fair Value		Gross Unrealized Losses
Total investments with unrealized losses	$	20,227	$	(743	)	$	43,772	$	(3,078	)
Unrealized losses with a loss position for less than 12 months		19,531		(533	)		42,114		(2,596	)
Unrealized losses with a loss position for more than 12 months		696		(210	)		1,658		(482	)

We have reviewed all of the securities included in the table above and have concluded that we have the ability and intent to hold these investments until their cost can be recovered, based upon the severity and duration of the decline. Therefore, we did not recognize any other-than-temporary impairment losses on these investments. Unrealized losses at November 30, 2012 were generally related to the volatility in valuations over the last several months for a portion of our portfolio of investments in marketable securities. The unrealized losses generally relate to investments whose fair values at November 30, 2012 were less than 15% below their original cost or have been in a loss position for less than six consecutive months. Although we have begun to see recovery in general economic conditions over the past year, if we were to experience continuing or significant unrealized losses within our portfolio of investments in marketable securities in the future, we may recognize additional other-than-temporary impairment losses. Such potential losses could have a material impact on our results of operations in any given reporting period. As such, we continue to closely evaluate the status of our investments and our ability and intent to hold these investments.

The net carrying values of debt securities at November 30, 2012, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.
