FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;To meet the financing needs of its customers, the Bank issues financial instruments which represent conditional obligations that are not recognized, wholly or in part, in the consolidated balance sheets.&amp;#160;&amp;#160;These financial instruments include commitments to extend credit under loan facilities and guarantees under standby and other letters of credit.&amp;#160;&amp;#160;Such instruments expose the Bank to varying degrees of credit and interest rate risk in much the same way as funded loans.&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 36pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;Revolving loan commitments are issued primarily to support commercial activities.&amp;#160;&amp;#160;The availability of funds under revolving loan commitments generally depends on whether the borrower continues to meet credit standards established in the underlying contract and has not violated other contractual conditions.&amp;#160;&amp;#160;A number of such commitments are used only partially or, in some cases, not at all before they expire.&amp;#160;&amp;#160;Nonrevolving loan commitments are issued mainly to provide financing for the acquisition and development or construction of real property, both commercial and residential, although not all are expected to lead to permanent financing by the Bank.&amp;#160;&amp;#160;Loan commitments generally have fixed expiration dates and may require payment of a fee.&amp;#160;&amp;#160;Credit card and personal credit lines are generally subject to cancellation if the borrower's credit quality deteriorates, and many lines remain partly or wholly unused.&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block;

During 2009, the Bank began offering interest rate swap agreements to commercial banking customers seeking to manage their interest rate risk.&amp;#160;&amp;#160;For each customer swap agreement, the Bank has entered into an offsetting agreement with an unrelated financial institution.&amp;#160;&amp;#160;These derivative financial instruments are carried at fair value, with changes in fair value recorded in &lt;/font&gt;current period earnings.&amp;#160; The aggregate notional amounts of both customer interest rate swap agreements and the offsetting agreements were each $78.9 million at June 30, 2010 and each $30.4 million at December 31, 2009.&amp;#160;&amp;#160;The fair value of these derivatives and the credit risk exposure to the Bank was immaterial at June 30, 2010 and December 31, 2009.&lt;/div&gt;</NonNumbericText>
