At December 31, 2019 and 2018, other borrowings are summarized as follows: The Corporation's subsidiary banks are members of the Federal Home Loan Bank (FHLB) and accordingly are permitted to obtain advances. There are $20.8 million of advances from the FHLB at December 31, 2019, and no advances at December 31, 2018, which accrue interest, payable monthly, at annual rates, primarily fixed, varying from 2.3% to 2.8% in 2019 and 1.6% to 2.4% during the year in 2018. FHLB advances are, generally, due in full at maturity. They are secured by eligible securities totaling $129.3 million at December 31, 2019, and $99.4 million at December 31, 2018, and a blanket pledge on real estate loan collateral. Based on this collateral and the Corporation's holdings of FHLB stock, the Corporation is eligible to borrow up to $212.3 million at year end 2019. Certain advances may be prepaid, without penalty, prior to maturity. The FHLB can adjust the interest rate from fixed to variable on certain advances, but those advances may then be prepaid, without penalty.
