Federal Home Loan Bank And Short Term Borrowings [Abstract] |
Federal Home Loan Bank and Short-term Borrowings | Note 6. Federal Home Loan Bank and Short-term Borrowings The Bank owned 12,023 shares of common stock of the FHLB at December 31, 2017. The Bank is required to maintain an investment of 0.09% of total assets with a dollar cap of $15 million, adjusted annually, plus 4.25% of total advances, adjusted for advances and repayments. The credit available under this facility is determined at 25% of the Bank’s total assets, or approximately $97.5 million at December 31, 2017. Short-term advances totaled $20,000,000 under this credit arrangement at December 31, 2017. This credit facility is secured by a floating lien on the Bank’s residential mortgage loan portfolio. Average short-term borrowings under this facility approximated $1,468,767 and $137 for 2017 and 2016, respectively. The Federal Home Loan Bank of Atlanta, convertible and adjustable advances total include the following: A $5,000,000 convertible advance issued in 2008, which has a final maturity of July 23, 2018, but is callable quarterly starting July 23, 2009. This advance has a 2.73% interest rate, with interest payable quarterly. The proceeds of the convertible advance were used to fund loans. A $5,000,000 convertible advance issued in 2008, which has a final maturity of August 22, 2018, but is callable quarterly starting August 22, 2011. This advance has a 3.34% interest rate, with interest payable quarterly. The proceeds of the convertible advance were used to fund loans. A $10,000,000, adjustable rate issued in 2017, which has a final maturity of November 1, 2018. This advance had a 1.38% interest rate at December 31, 2017, with interest payable quarterly. The proceeds of the adjustable advance were used to fund loans. The Bank also had available unsecured federal funds lines of credit from two financial institutions for $5.0 million and $6.0 million at December 31, 2017. No balances were outstanding on these lines of credit on December 31, 2017. Derivatives During the fourth quarter of 2017, the Company entered into interest rate swaps to manage interest rate risk. These derivative contract involves the receipt of floating rate interest from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreement, without the exchange of the underlying notional value. These instruments are designated as a cash flow hedges as the receipt of floating rate interest from the counterparty is used to manage interest rate risk associated with forecasted issuances of short-term FHLB advances. The change in the fair value of this hedging instrument is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged transaction affects earnings. For derivative financial instruments accounted for as hedging instruments, we formally designate and document, at inception, the financial instrument as a hedge of a specific underlying exposure, the risk management objective, and the manner in which the effectiveness of the hedge will be assessed. We formally assess both at inception and at each reporting period thereafter, whether the derivative financial instruments used in hedging transactions are effective in offsetting changes in cash flows of the related underlying exposures. Any ineffective portion of the changes in cash flow of the instruments is recognized immediately into earnings. ASC 815-10, Derivatives and Hedging (“ASC 815”) requires companies to recognize all derivative instruments as assets or liabilities at fair value in the consolidated balance sheets. In accordance with ASC 815, we designated our interest rate swaps as cash flow hedges of certain active and forecasted variable rate FHLB advances. Changes in the fair value of the hedging instrument, except any ineffective portion, were recorded in accumulated other comprehensive income (loss) until earnings were impacted by the hedged instrument. No components of our hedging instruments were excluded from the assessment of hedge effectiveness in hedging exposure to variability in cash flows. Classification of the gain or loss in the consolidated statements of income upon release from accumulated other comprehensive income (loss) is the same as that of the underlying exposure. We discontinue the use of hedge accounting prospectively when (1) the derivative instrument is no longer effective in offsetting changes in fair value or cash flows of the underlying hedged item; (2) the derivative instrument expires, is sold, terminated, or exercised; or (3) designating the derivative instrument as a hedge is no longer appropriate. When we discontinue hedge accounting because it is no longer probable that an anticipated transaction will occur in the originally expected period, or within an additional two-month period thereafter, changes to fair value that were recorded in accumulated other comprehensive income (loss) are recognized immediately in earnings. As of December 31, 2017, the Company had three outstanding interest rate swaps designated as a cash flow hedges with an aggregate notional value of $20.0 million. The agreements have five year terms and stipulate that the counterparty will pay the Company interest at three-month LIBOR and the Company will pay fixed rates of interest at 2.105%, 2.235% and 2.246% on the $10.0 million, $5.0 million and $5.0 million notional amounts, respectively. These interest rate swaps of $10.0 million, $5.0 million and $5.0 million mature on October 2022, July 2023, and August 2023, respectively, and hedge three-month FHLB advances that will be renewed every three months at the LIBOR interest rate at that time. The two $5.0 million contracts are forward starting swap that become effective in July 2018 and August 2018. After-tax unrealized gains of $21,000, $7,000 and 7,000 were recognized in accumulated other comprehensive income for the year ended December 31, 2017 and there was no ineffective portion of these hedges. No interest rate swaps designated as cash flow hedges were outstanding during 2016. The Company pays or receives the net interest amount quarterly and includes this amount as part of FHLB advances interest expense on the consolidated income statements. The cash flow hedges were determined to be fully effective during all periods presented. As such, no ineffectiveness has been included in net income.
