Commitments and Contingencies Loan Commitments Legally binding 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 commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. In the normal course of business, there are various outstanding commitments to extend credit that are not reflected in the consolidated financial statements. At June 30, 2019 and June 30, 2018 , respectively, loan commitments (excluding $181,477 and $209,726 of undisbursed portions of construction loans) totaled $93,432 and $49,949 of which $34,631 and $19,812 were variable rate commitments and $58,801 and $30,137 were fixed rate commitments. The fixed rate loans had interest rates ranging from 2.69% to 8.59% at June 30, 2019 and 2.10% to 6.15% at June 30, 2018 , and terms ranging from three to 30 years. Pre-approved but unused lines of credit (principally second mortgage home equity loans and overdraft protection loans) totaled $353,663 and $491,649 at June 30, 2019 and 2018 , respectively. These amounts represent the Companys exposure to credit risk, and in the opinion of management have no more than the normal lending risk that the Company commits to its borrowers. The Company has two types of commitments related to loans held for sale: rate lock commitments and forward loan sale commitments. Rate lock commitments are commitments to extend credit to a customer that has an interest rate lock and are considered derivative instruments. The rate lock commitments do not qualify for hedge accounting. In order to mitigate the risk from interest rate fluctuations, we enter into forward loan sale commitments on a best efforts basis, which do not meet the definition of a derivative instrument. The fair value of these commitments was not material at June 30, 2019 or June 30, 2018 . The Company grants construction and permanent loans collateralized primarily by residential and commercial real estate to customers throughout its primary market area. In addition, the Company grants equipment financing throughout the eastern United States and municipal leases to customers throughout North and South Carolina. The Companys loan portfolio can be affected by the general economic conditions within these market areas. Management believes that the Company has no significant concentration of credit in the loan portfolio. Restrictions on Cash The Bank is required by regulation to maintain a varying cash reserve balance with the Federal Reserve System. The daily average calculated cash reserve required as of June 30, 2019 and 2018 was $2,633 , and $2,304 , respectively, which was satisfied by vault cash and balances held at the Federal Reserve Bank. Guarantees Standby letters of credit obligate the Company to meet certain financial obligations of its customers, if, under the contractual terms of the agreement, the customers are unable to do so. The financial standby letters of credit issued by the Company are irrevocable and payment is only guaranteed upon the borrowers failure to perform its obligations to the beneficiary. Total commitments under standby letters of credit as of June 30, 2019 and 2018 were $9,460 and $8,227 , respectively. There was no liability recorded for these letters of credit at June 30, 2019 or June 30, 2018 . Litigation The Company is involved in several litigation matters in the ordinary course of business. These proceedings and the associated legal claims are often contested and the outcome of individual matters is not always predictable. These claims and counter claims typically arise during the course of collection efforts on problem loans or with respect to actions to enforce liens on properties in which the Company holds a security interest. There can be no assurance that loan workouts and other activities will not expose the Company to additional legal actions, including lender liability or environmental claims. Therefore, the Company may be exposed to substantial liabilities, which could adversely affect its results of operations and financial condition. Moreover, the expenses of legal proceedings will adversely affect its results of operations until they are resolved. The Company is not a party to any pending legal proceedings that management believes would have a material adverse effect on the Companys financial condition or results of operations.
