The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions based on available information that affect the amounts reported in the financial statements and disclosures provided, including the accompanying notes, and actual results could differ. Material estimates, that are particularly susceptible to change, include the allowance for credit losses for loans, off-balance sheet commitments and available for sale securities; fair value measurements of assets and liabilities; and income taxes. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the Company’s consolidated financial statements in the period they are deemed necessary. While management uses its best judgment, actual results could differ from those estimates.</span>

The Company may provide modifications to borrowers experiencing financial difficulty in the form of principal forgiveness, interest rate reductions, other-than-insignificant payment delays, or term extensions. When principal forgiveness is provided, the amount of forgiveness is charged-off against the allowance for credit losses. In some cases, the Company may provide multiple types of concessions on one loan. The Company will evaluate whether the modification represents a new loan or a continuation of an existing loan. The Company assesses all loan modifications to determine whether they were made to borrowers experiencing financial difficulty.</span>
