We periodically hold interest rate derivative instruments to mitigate exposure to changes in interest rates, in particular one-month LIBOR, with $562.1 million and $468.5 million of our borrowings at December 31, 2015 and 2014, respectively, at variable rates. As a matter of policy, we do not use derivatives for speculative purposes. We currently have no interest rate swap agreements in place. During 2013 we were a party to one interest rate swap agreement with a notional outstanding amount of $100.0 million with a fixed rate of 2.10%. The swap agreement expired in November 2013. The remaining effective portion of these hedges at the swap expiration date was amortized into earnings over the term of the underlying borrowings.There was no expense or benefit recorded related to derivative instruments for the year ended December 31, 2015. We recorded a ($0.5 million) benefit and $1.5 million expense to net finance costs during the years ended December 31, 2014 and December 31, 2013 respectively.

The Company estimates the fair value of  derivative instruments using a discounted cash flow technique and has used creditworthiness inputs that corroborate observable market data evaluating the Company’s and counterparties’ risk of non-performance. Valuation of the derivative instruments requires certain assumptions for underlying variables and the use of different assumptions would result in a different valuation. Management believes it has applied assumptions consistently during the period. We apply hedge accounting and account for the change in fair value of our cash flow hedges through other comprehensive income for all derivative instruments.

Earnings Effects of Derivative Instruments on the Statements of Income

Our derivatives were designated in a cash flow hedging relationship with the effective portion of the change in fair value of the derivative reported in the cash flow hedges subaccount of accumulated other comprehensive income.

* These amounts are shown net of $1.9 million of interest payments reclassified to the income statement during the year ended December 31, 2013.  No interest payments were reclassified to the income statement in 2015 and 2014.

The effective portion of the change in fair value on a derivative instrument designated as a cash flow hedge is reported as a component of other comprehensive income and is reclassified into earnings in the period during which the transaction being hedged affects earnings or it is probable that the forecasted transaction will not occur. The ineffective portion of the hedges is recorded in earnings in the current period. However, these are highly effective hedges and no significant ineffectiveness occurred in either of the periods presented.

Counterparty Credit Risk

The Company evaluates the creditworthiness of the counterparties under its hedging agreements. The swap counterparty for the interest rate swap in place during the first eleven months of 2013 was a large financial institution in the United States that possessed an investment grade credit rating. Based on this rating, the Company believes that the counterparty was creditworthy and that their continuing performance under the hedging agreement was probable, and did not require the counterparty to provide collateral or other security to the Company.
