Fair Value Measurements</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     The Company utilizes a valuation hierarchy for disclosure of the inputs to the valuations used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company’s own assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     At March 31, 2011, $1.8 million of the Company’s marketable securities are valued as level 1 investments. In addition, the Company held $4.9 million of marketable securities in an institutional diversified equity securities mutual fund. These securities are valued as level 2 investments. The marketable securities are shown as a separate line on the consolidated balance sheet. For the three months ended March 31, 2011, gains and losses on the investments noted above were not significant. No transfers between level 1 and level 2 investments occurred during the three months ended March 31, 2011. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Fair value of the institutional equity securities mutual fund was estimated using the net asset value of the Company’s ownership interests in the fund’s capital. The mutual fund seeks to provide long-term growth of capital by investing primarily in equity securities traded on U.S. exchanges and issued by large, established companies across many business sectors. Fair value of the fixed-income securities was estimated using observable market inputs and the securities are primarily corporate debt instruments and U.S. Government securities. There are no restrictions on the Company’s ability to redeem these equity and fixed-income securities investments. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif"> <div align="center" style="font-size: 10pt; margin-top: 0pt"> <b> </b> </div> </div>  <!-- Begin Block Tagged NotefalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringThis item represents the complete disclosure regarding the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments, assets, and liabilities.
