Short-term borrowings are for terms under or equal to one year and are comprised of securities sold under repurchase agreements, or REPOs, and Federal Home Loan Bank, or FHLB, advances. All REPOs are overnight short-term investments and are not insured by the Federal Deposit Insurance Corporation. Securities pledged as collateral under these REPO financing arrangements cannot be sold or repledged by the secured party and therefore, the REPOs are accounted for as a secured borrowing. Mortgage-backed securities with a total carrying value of $46.7 million at September 30, 2017 and $53.2 million at December 31, 2016 were pledged as collateral for these secured transactions. The pledged securities are held in safekeeping at the Federal Reserve. Due to the overnight short-term nature of REPOs, potential risk due to a decline in the value of the pledged collateral is low. Collateral pledging requirements with REPOs are monitored daily. FHLB advances are for various terms and are secured by a blanket lien on residential mortgages and other real estate secured loans.

Long-term borrowings are for original terms greater than one year and are comprised of FHLB advances, a capital lease and junior subordinated debt securities. Long-term FHLB advances are secured by the same loans as short-term FHLB advances. We had total long-term borrowings outstanding of $9.7 million at a fixed rate and $3.1 million at a variable rate at September 30, 2017, excluding our capital lease of $0.1 million.
