At June 30, 2010 and December 31, 2009, the Company had 16 securities and 23 securities, respectively, in an unrealized loss position. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost of the investments. The Company does not consider its investments in municipal securities with a current unrealized loss position to be other-than-temporarily impaired at June 30, 2010 because the Company does not intend to sell the investments and it is more likely than not that the Company will not be required to sell the investments before recovery of their amortized cost. However, investments in an unrealized loss position deemed to be temporary at June 30, 2010 that have a contractual maturity of greater than 12 months have been classified as non-current marketable securities under the caption “Marketable securities, net of current portion,” reflecting the Company’s current intent and ability to hold such investments to maturity. The Company’s investments in municipal securities are classified as available-for-sale. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif"> <div align="justify" style="font-size: 10pt;
