Quarterly, commencing September 17, 2012, under the terms of the forward swap, the Company will pay interest at a fixed rate of 7.02% until March 15, 2019. On May 26, 2010, the Company entered into a forward swap with a notional amount of $9,000,000 effective December 15, 2015, which hedges against changes in cash flows following the termination of the fixed rate period.

The swap liability is reported as a component of other liabilities on the consolidated balance sheets. A net valuation gain of $110,000 (net of tax) is included in accumulated other comprehensive income related to the swap agreements at June 30, 2017. A net valuation gain of $256,000 (net of tax) was included in accumulated other comprehensive income related to the swap at December 31, 2016.

We use dollar offset at the hedge's inception and for each reporting period thereafter to assess whether the derivative used in a hedging transaction is expected to be, and has been, effective in offsetting changes in the fair value of the hedged item. Since inception, no portion of the hedged item has been deemed ineffective. For all hedges, we discontinue hedge accounting if it is determined that a derivative is not expected to be, or has ceased to be, effective as a hedge.

The Company’s interest rate swaps include provisions requiring the Company to post collateral when the derivative is in a net liability position.

At December 31, 2016, the Company had securities on deposit with fair market values of $1,466,000 and cash of $231,000 (all of which is posted as collateral).
