5.  Derivative Instruments

We have periodically held interest rate derivative instruments to mitigate exposure to changes in interest rates, in particular one-month LIBOR, with $508.8 million and $468.5 million of our borrowings at June 30, 2015 and December 31, 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. We recorded a $0.1 million and $0.2 million benefit to net finance costs during the three and six month periods ended June 30, 2014, respectively.

The Company estimates the fair value of derivative instruments using a discounted cash flow technique and uses creditworthiness inputs that can be corroborated by 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. 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.

Our derivatives are 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.

We hold interest rate derivative instruments from time to time to mitigate exposure to changes in interest rates, in particular one-month LIBOR, with $508.8 million of our borrowings at June 30, 2014 at variable rates. The last of our interest rate derivatives terminated on November 25, 2013, at which time the liabilities under derivative instruments decreased to nil.

The change in fair value on a derivative instrument designated as a cash flow hedge is reported as a component of accumulated 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.

As of June 30, 2014, we had $0.2 million in accumulated other comprehensive income related to a previously held derivative instrument designated as a cash flow hedge.  This amount was reclassified into interest expense through December 2014, the remaining term of the associated debt.  For the quarters ended June 30, 2015 and June 30, 2014, interest expense was reduced by zero and $0.1 million respectively, as a result of this reclassification out of accumulated other comprehensive income.

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 had not required the counterparty to provide collateral or other security to the Company.
