[1] (1) The provision (credit) for loan losses excludes any impact for the change in the reserve for unfunded commitments, which represents management's estimate of the amount required to reflect the probable inherent losses on outstanding letters of credit and unused lines of credit. The reserve for unfunded commitments was presented within accrued interest and other liabilities on the consolidated statements of condition. At December 31, 2019, 2018, and 2017, the reserve for unfunded commitments was $21,000, $22,000 and $20,000, respectively.
