DERIVATIVE INSTRUMENTS

Commodity Derivative Instruments

As of September 30, 2018, the Company had 2.1 million mmBTUs (millions of British Thermal Units) in aggregate notional amount outstanding natural gas swap contracts to manage commodity price exposures. All of these contracts mature by July 31, 2019. The Company elected to designate these derivative instruments as cash flow hedges in accordance with ASC 815-20, "Derivatives – Hedging". No ineffectiveness was recorded on these contracts during the three and nine months ended September 30, 2018 and 2017.

Interest Rate Derivative Instrument

In September 2016, the Company entered into interest rate swap agreements for a combined notional amount of $100.0 million with a term of four years, which hedged the floating LIBOR on a portion of the term loan under the Amended and Restated Credit Agreement to an average fixed rate of 1.323% and LIBOR floor of 0.75%. The Company elected to designate these interest rate swaps as cash flow hedges for accounting purposes.

On March 29, 2018, the Company terminated its interest rate swap agreements that were previously designated as a cash flow hedge and received $3.2 million in cash, the fair value of the swap on the termination date. The unrealized gain at termination remains in accumulated other comprehensive income and will be amortized into interest expense over the life of the original hedged instrument. On the same date, the Company entered into new interest rate swap agreements for a combined notional amount of $100.0 million, which expire on September 30, 2020 and hedge the floating LIBOR on a portion of the term loan under the Amended and Restated Credit Agreement to an average fixed rate of 2.46% and LIBOR floor of 0.75%. The Company elected to designate these interest rate swaps as cash flow hedges for accounting purposes. No ineffectiveness was recorded on these contracts during the three and nine months ended September 30, 2018 and 2017.
