Allowance for Credit Losses - Off-Balance Sheet Credit Exposures

The allowance for credit losses on off-balance sheet credit exposures is a liability account, calculated in accordance with ASC 326, representing expected credit losses over the contractual period for which the Company is exposed to credit risk resulting from a contractual obligation to extend credit. No allowance is recognized if the Company has the unconditional right to cancel the obligation. Off-balance sheet credit exposures primarily consist of amounts available under outstanding lines of credit and letters of credit. For the period of exposure, the estimate of expected credit losses considers both the likelihood that funding will occur and the amount expected to be funded over the estimated remaining life of the commitment or other off-balance sheet exposure. The likelihood and expected amount of funding are based on historical utilization rates. The amount of the allowance represents management's best estimate of expected credit losses on commitments expected to be funded over the contractual life of the commitment. The allowance is reported as a component of accrued interest and other liabilities in the Company's consolidated balance sheets. Adjustments to the allowance are reported in the Company's income statement as a component of provision for credit losses - off-balance sheet exposures.

Estimating credit losses on amounts expected to be funded uses the same methodology as described for loans in note 1 - Summary of Significant Accounting Policies, letter (f) Allowance for Credit Losses - Loans as if such commitments were funded.
