Actual results could differ from those estimates. The allowance for credit losses, the fair value of financial instruments and the status of contingencies are particularly susceptible to significant change.</span></div>

The Company considers the following arrangements to be guarantees: commitments to extend credit, standby letters of credit and indemnification agreements included within third party contractual arrangements.</span></div><div style="margin-top:5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit that involve varying degrees of credit risk in excess of the amount recognized on the consolidated balance sheets. The Company’s exposure to credit loss in the event of non-performance by the other party to these financial instruments is represented by the contractual amount of the instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the borrower.</span></div><div style="margin-top:5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. Commitments to extend credit do not include mortgage finance arrangements with mortgage loan originators through the mortgage warehouse lending division, which are established as uncommitted “guidance” purchase and sale facilities under which the mortgage originator has no obligation to offer and the Company has no obligation to purchase interests in the mortgage loans subject to the arrangements.</span></div><div style="margin-top:5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.</span></div><div style="margin-top:5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In conjunction with the sale and securitization of loans held for sale and their related servicing rights, the Company may be exposed to liability resulting from recourse, repurchase and make-whole agreements. If it is determined subsequent to the sale of a loan or its related servicing rights that a breach of the representations or warranties made in the applicable sale agreement has occurred, which may include guarantees that prepayments will not occur within a specified and customary time frame, the Company may have an obligation to either (a) repurchase the loan for the unpaid principal balance, accrued interest and related advances, (b) indemnify the purchaser against any loss it suffers or (c) make the purchaser whole for the economic benefits of the loan and its related servicing rights. The repurchase, indemnification and make-whole obligations vary based upon the terms of the applicable agreements, the nature of the asserted breach and the status of the mortgage loan at the time a claim is made. The Company establishes reserves for estimated losses of this nature inherent in the sale of mortgage loans by estimating the </span></div>losses inherent in the population of all loans sold based on trends in claims and actual loss severities experienced. The reserve will include accruals for probable contingent losses in addition to those identified in the pipeline of claims received.
