8. COMMITMENTS AND CONTINGENCIES Litigation Matters In the ordinary course of its operations, the Company and its subsidiaries are parties to various legal proceedings. Based on the information presently available, and after consultation with legal counsel, management believes that the ultimate outcome in such proceedings, in the aggregate, will not have a material adverse effect on the business, financial condition, or results of operations of the Company. Financial Instruments with Off-Balance Sheet Risk 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 and to reduce its own exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve elements of credit and interest rate risk in excess of the amount recognized on the Companys Consolidated Balance Sheet. The contractual amounts of these instruments reflect the extent of the Companys involvement in particular classes of financial instruments. The Companys exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit and letters of credit written is represented by the contractual amount of these instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Unless noted otherwise, the Company does not require collateral or other security to support off-balance sheet financial instruments with credit risk. The Company considers credit losses related to off-balance sheet commitments by undergoing a similar process in evaluating losses for loans that are carried on the balance sheet. The Company considers historical loss rates, current economic conditions, risk ratings, and past due status among other factors in the consideration of whether credit losses are inherent in the Companys off-balance sheet commitments to extend credit. The Company also records an indemnification reserve that includes balances relating to mortgage loans previously sold based on historical statistics and loss rates. As of June 30, 2019 and December 31, 2018, the Companys reserves for off-balance sheet credit risk and indemnification were $2.8 million and $1.4 million, respectively. Commitments to extend credit are agreements to lend to customers as long as there are no violations of any conditions established in the contracts. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Because many of the commitments may expire without being completely drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Letters of credit are conditional commitments issued by the Company to guarantee the performance of customers to third parties. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers.

(1) Includes unfunded overdraft protection. ? ? ? ? ? ? ? The Company must maintain a reserve against its deposits in accordance with Regulation D of the Federal Reserve Act. For the final weekly reporting period in the period ended June 30, 2019, the aggregate amount of daily average required reserves was approximately $41.2 million and was satisfied by deposits maintained with the Federal Reserve Bank. As of June 30, 2019, the Company had approximately $101.2 million in deposits in other financial institutions, of which $78.9 million served as collateral for cash flow and loan swap derivatives. The Company had approximately $20.0 million in deposits in other financial institutions that were uninsured at June 30, 2019. At least annually, the Companys management evaluates the loss risk of its uninsured deposits in financial counterparties. For asset/liability management purposes, the Company uses interest rate swap agreements to hedge various exposures or to modify the interest rate characteristics of various balance sheet accounts.
