Repurchase and Resale Agreements Policy	Securities purchased under agreements to resell ("resale agreements") are carried at the amounts at which the securities will be subsequently resold as specified in the agreements. Resale agreements are utilized to invest excess funds on a short-term basis. At December 31, 2019, the Company had $107,157,000 invested in resale agreements, all of which settled on January 2, 2020 and were subsequently reinvested. The Company maintains control of securities that are purchased under resale agreements in a triparty account. The third-party agent, acting on behalf of the Company, values the collateral on a daily basis (102% is required) and obtains additional collateral, if necessary, to protect the Company in the event of default by the counterparties.
