The Corporation's subsidiary banks are members of the Federal Home Loan Bank (FHLB) and accordingly are permitted to obtain advances. The advances from the FHLB of $132 thousand at December 31, 2016, and $12.7 million, including $12.5 million at December 31, 2015 contractually due and a purchase premium of $223 thousand, accrue interest, payable monthly, at annual rates, primarily fixed, varying from 0.5% to 6.6% in 2016 and 0.6% to 6.6% in 2015. The advances are due at various dates through August 2017. FHLB advances are, generally, due in full at maturity. They are secured by eligible securities totaling $57.1 million at December 31, 2016, and $70.3 million at December 31, 2015, 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 $169.2 million at year end 2016. 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.
