In addition, the Company assigned to Belrose the Company&amp;#8217;s existing license agreement with Zhejiang Hisun Pharmaceutical Co., Ltd. Under the Belrose APA, the Company also agreed to sell all of its right, title and interest in the Locked Nucleic Acid (LNA) Technology platform and related assets to Belrose at a second closing, provided that prior to July 15, 2013, the Company enters into an agreement with Santaris Pharma A/S (&amp;#8220;Santaris&amp;#8221;) to resolve any contractual obligations that the parties may have under the Company&amp;#8217;s license agreement with Santaris and an agreement with Santaris and Belrose providing for Belrose&amp;#8217;s assumption of such license agreement.&lt;/p&gt;

The Belrose APA also entitles the Company to receive from Belrose additional potential payments, including a share of net revenues that may be received from Hisun related to PEG-SN38 rights in China as well as a share of other potential partnering revenues.

The Company includes realized gain and losses, if any, in the accompanying Condensed Consolidated Statements of Comprehensive Income (Loss), in Interest and Other Income.

When the fair value of an investment is less than its 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. As of March 31, 2013 and December 31, 2012, marketable securities with fair value of $34.1 million and $38.1 million respectively were in an unrealized loss position. However, 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.&lt;/p&gt;

Fair value is determined from available Level 2 vendor quoted prices utilizing observable inputs based on active markets. The Company utilizes a financial institution to provide pricing for securities in the Company&amp;#8217;s portfolio, and reviews documentation from the sources that detailed the pricing techniques and methodologies used by these sources and determines if their policies adequately considered market activity, either based on specific transactions for the particular security type or based on modeling of securities with similar credit quality, duration, yield and structure that were recently transacted. The Company continues to monitor any changes or modifications to their process by reviewing their documentation on internal controls for pricing and market reviews.&lt;/p&gt;</us-gaap:InvestmentsInDebtAndMarketableEquitySecuritiesAndCertainTradingAssetsDisclosureTextBlock>

In March 2013, in an effort to continue to cut ongoing operating expenses, the Company committed to a plan to reduce its workforce from 19 employees to 12 employees. During the first quarter of 2013, the Company incurred restructuring charges of $2.5 million, of which $1.6 million resulted in cash expenditures paid and expensed during the quarter and $0.9 million remained to be paid for one-time employee termination benefits and associated costs.&lt;/p&gt;&lt;p style="text-align: justify; text-indent: 0.5in; 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;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;&lt;p style="text-align: justify; text-indent: 0.5in; margin: 0pt 0px;

<us-gaap:DebtConversionDescription contextRef="Context_3ME_31-Mar-2013">The 4% convertible notes mature on June 1, 2013 unless earlier redeemed repurchased or converted. The 4% convertible notes are senior unsecured obligations and rank equal to all future senior unsecured debt of the Company. As of March 31, 2013, the principal amount of the Company's 4% convertible notes outstanding was $115.8 million. After giving effect to a required adjustment to the conversion price of the Company's 4% convertible notes resulting from the December 2012 special cash dividend, the Company's 4% convertible notes are currently convertible until maturity at the option of the holder into shares of the Company's common stock at a conversion price of $6.76 per share (or a conversion rate of 147.8211 shares per $1,000 principal amount). At March 31, 2013, the potential dilutive effect of conversion of the 4% convertible notes was 17.1 million shares using the conversion price of $6.76 per share. If the closing price of the Company'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 percent of the applicable conversion price on the date of such notice, the Company, at its option, may redeem the 4% convertible notes in whole or in part, at a redemption price in cash equal to 100 percent of the principal amount of the 4% convertible notes to be redeemed, plus accrued and unpaid interest, if any, to the redemption date.</us-gaap:DebtConversionDescription>
