&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;As of June 30,
2013 and December 31, 2012 our investments were comprised of liquid
money market funds with no maturity dates. Accordingly, there were
no available-for-sale securities with unrealized gains or
unrealized losses.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN-TOP: 12px; TEXT-INDENT: 8%; MARGIN-BOTTOM: 0px"&gt;
&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Gross realized
gains from the sale or maturity of available-for-sale investments
were zero during each of the three and six month periods ended
June&amp;#xA0;30, 2013 and 2012. The Company did not record any gross
realized losses from the sale or maturity of available-for-sale
investments during the three and six months ended June&amp;#xA0;30,
2013, and 2012.&lt;/font&gt;&lt;/p&gt;
