&lt;div style="margin-top: 6pt; font-size: 10pt;" align="left"&gt;At December&amp;nbsp;31, 2009, we held $42.0&amp;nbsp;million at par value in auction rate securities, which are variable rate bonds tied to short-term interest rates that reset through a Dutch auction at predetermined short intervals. Of the total investment, $30.8&amp;nbsp;million, in par value, were included in a settlement agreement with UBS that allowed us to sell, or put, these auction rate securities back to UBS at par value at any time during the period from June&amp;nbsp;30, 2010 through July&amp;nbsp;2, 2012. In 2010, we redeemed these securities at par. Consequently, we reversed the other-than-temporary impairment of $2.3&amp;nbsp;million on the fair value of auction rate securities held at December&amp;nbsp;31, 2009 and the offsetting gain of $2.3&amp;nbsp;million on the fair value of the settlement agreement. These changes are reflected in Other income (expense), net on the Consolidated Statement of Operations for 2010. At December&amp;nbsp;31, 2009, the fair value of the auction rate securities covered under this agreement was $28.5&amp;nbsp;million, a decline of $2.3&amp;nbsp;million from par, but an improvement in the $3.1 million impairment recognized at December&amp;nbsp;31, 2008. We recognized the $0.8&amp;nbsp;million improvement in the 2009 fair market value in Other income (expense), net on the Consolidated Statement of Operations and an offsetting $0.8&amp;nbsp;million decline on the fair value of the assessment of the settlement agreement in Other income (expense), net on the Consolidated Statement of Operations for 2009. &lt;/div&gt;

&lt;div style="margin-top: 6pt; font-size: 10pt;" align="left"&gt;The remaining $11.2&amp;nbsp;million investment in auction rate securities at December&amp;nbsp;31, 2009 was not covered under the settlement agreement with UBS, was classified as available for sale, and was carried at fair value with any unrealized gains and losses recorded in Other Comprehensive Income. In 2010, we sold these securities for $10.7&amp;nbsp;million and recognized the $0.5&amp;nbsp;million loss in Other income (expense), net on the Consolidated Statement of Operations. The fair value of the auction rate securities not covered under the settlement agreement with UBS at December&amp;nbsp;31, 2009 was $11.1 million, a decline of $0.1&amp;nbsp;million from par value. The decline in fair value was assessed as temporary and was recorded as an unrealized loss in Accumulated Other Comprehensive Income (Loss), net of tax of $0.04&amp;nbsp;million. Based on a lack of current market liquidity, we classified these securities as non-current. &lt;/div&gt;&lt;/div&gt; &lt;/div&gt;</NonNumbericText><NonNumericTextHeader>2. Marketable Securities

Other trading assets include assets that are carried on the balance sheet at fair value and held for trading purposes.  A debt security represents a creditor relationship with an enterprise that is in the form of a security. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt.
