&lt;p style="text-align: justify; text-indent: 0.5in; margin: 0pt 0px; font: 10pt times new roman, times, serif;"&gt;Impairment assessments are made at the individual security level each reporting period. When the fair value of an investment is less than its amortized cost at the balance sheet date, a determination is made as to whether the impairment is other-than-temporary and, if it is other-than-temporary, an impairment loss is recognized in earnings equal to the difference between the investment&amp;#8217;s amortized cost and fair value at such date. The cost of securities is based on the specific-identification method. As of June 30, 2012 and December 31, 2011, some of the Company&amp;#8217;s investments in marketable debt securities were in an unrealized loss position. None of the underlying investments has been in a continuous loss position longer than twelve months, and no other-than-temporary impairment is deemed to have occurred. The Company maintains a current liability for the fair value of the investments in the Executive Deferred Compensation Plan, and any gains or losses ultimately realized related to these holdings are borne by the plan participants.&lt;/p&gt;</us-gaap:InvestmentsInDebtAndMarketableEquitySecuritiesAndCertainTradingAssetsDisclosureTextBlock>

The notes are senior unsecured obligations and rank equal to all future senior unsecured debt of the Company. The notes are convertible at the option of the holders into the Company&amp;#8217;s common stock at a conversion price of $9.55 per share (104.712 shares per $1,000 of principal amount). If the closing price of the Company&amp;#8217;s common stock for at least 20 trading days in the 30-consecutive-trading-day period ending on the date one day prior to the date of a notice of redemption is greater than 140% of the applicable conversion price on the date of such notice, the Company, at its option, may redeem the notes in whole or in part, at a redemption price in cash equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to the redemption date. Upon occurrence of a &amp;#8220;fundamental change,&amp;#8221; as defined in the indenture governing the notes, holders of the notes may require the Company to redeem the notes at a price equal to 100% of the principal amount plus accrued and unpaid interest or, in certain cases, to convert the notes at an increased conversion rate based on the price paid per share of the Company&amp;#8217;s common stock in the transaction constituting the fundamental change.&lt;/p&gt;

This program was suspended during the third quarter of 2011. During the first quarter of 2012, the Company announced its plans to resume repurchasing its outstanding common stock under this program, but no shares were actually repurchased during the first quarter. During the second quarter of 2012, the Company repurchased and retired 788,300 shares at a cost of $5.3 million, or an average cost of approximately $6.77 per share, under this program. Since the inception of this program, the cumulative number of shares repurchased and retired through June 30, 2012 amounted to 12,249,749 shares at a total cost of $126.8 million, or an average cost of approximately $10.36 per share.

Income tax payments of $33,000 and $5,000 were made during the six months ended June 30, 2012 and 2011, respectively.&lt;/p&gt;</us-gaap:CashFlowSupplementalDisclosuresTextBlock>

Prior to the sale, the Company&amp;#8217;s research and development function was engaged in, among other things, studies oriented towards the next-generation formulations of Oncaspar and Adagen, two products that were among those sold as part of the specialty pharmaceuticals business. The in-process research and development related to those two products was included in the sale. The selling price was management&amp;#8217;s best estimate of its stand-alone fair value based on the stage of development and consideration of future milestone payments. During the first quarter of 2011, the Company earned the first $5.0 million milestone payment from the purchaser of the specialty pharmaceutical business resulting from the approval of a supplemental Biologic License Application (sBLA) for the manufacture of Oncaspar.&lt;/p&gt;</enzn:SaleOfInProcessResearchAndDevelopmentDisclosureTextBlock>

&lt;p style="text-align: justify; text-indent: 0.5in; margin: 0pt 0px; font: 10pt times new roman, times, serif;"&gt;Basic loss and earnings per common share is computed by dividing the loss or income available to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Restricted stock units (nonvested shares) are not considered to be outstanding shares until the vesting criteria (service and/or performance) have been satisfied.&lt;/p&gt;
&lt;p style="text-align: justify; margin: 0pt 0px; font: 10pt times new roman, times, serif;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="text-align: justify; text-indent: 0.5in; margin: 0pt 0px; font: 10pt times new roman, times, serif;"&gt;For purposes of calculating diluted earnings per common share, the denominator includes both the weighted-average number of shares of common stock outstanding and the number of common stock equivalents if the inclusion of such common stock equivalents is dilutive. Dilutive common stock equivalents potentially include stock options and nonvested shares using the treasury stock method, shares issuable under the employee stock purchase plan (ESPP) and the number of shares issuable upon conversion of the Company&amp;#8217;s convertible notes payable. In the case of notes payable, the diluted earnings per share calculation is further affected by an add-back of interest expense to the numerator under the assumption that the interest would not have been incurred if the notes payable were converted into common stock.&lt;/p&gt;

&lt;p style="text-align: justify; text-indent: 0.5in; margin: 0pt 0px; font: 10pt times new roman, times, serif;"&gt;The Company has incurred costs from restructuring activities undertaken during 2010 and 2011 as part of the transition from a fully integrated biopharmaceutical company with research, manufacturing, and marketing operations to a biotechnology company focused primarily on research and development. During the second half of 2011, the Company incurred additional restructuring costs as part of a plan to more closely align its resources and capital with on-going research and development activities. Restructuring costs are charged to earnings and accrued as a liability at the time they are considered probable and reasonably estimable. Restructuring costs include employee separation benefits and lease termination costs for facilities that have been vacated.&lt;/p&gt;
