Derivative Instruments

The Company utilizes interest rate swap agreements to fix the LIBOR-based variable portion of the interest rate on its long term debt. Terms of the interest rate swap agreements require the Company to receive a variable interest rate and pay a fixed interest rate. As of March 31, 2016, the Company had interest rate swap agreements in place that hedge a notional value of debt ranging from approximately $251.5 million to approximately $192.7 million and amortize consistent with future debt principal payments. The interest rate swap agreements establish fixed interest rates in a range of 0.74% to 2.68% with various expiration terms extending to June 30, 2020. At inception, the interest rate swaps were and continue to be designated as cash flow hedges.

As of March 31, 2016 and December 31, 2015, the fair value carrying amount of the Company's derivative instruments are recorded as follows:

The following table summarizes the loss recognized in accumulated other comprehensive income or loss ("AOCI") and the amounts reclassified from AOCI into earnings as of March 31, 2016 and December 31, 2015, and for the three months ended March 31, 2016 and 2015:

	Amount of Loss Recognized in AOCI on Derivative (Effective Portion, net of tax)							Amount of Loss Reclassified from AOCI into Earnings
								Three months ended March 31,

Over the next 12 months, the Company expects to reclassify approximately $0.8 million of pre-tax deferred losses from AOCI to interest expense as the related interest payments for the designated interest rate swaps are funded.

The fair value of the Company's derivatives are estimated using an income approach based on valuation techniques to convert future amounts to a single, discounted amount. Estimates of the fair value of the Company's interest rate swaps use observable inputs such as interest rate yield curves. Fair value measurements and the fair value hierarchy level for the Company's assets and liabilities measured at fair value on a recurring basis as of March 31, 2016 and December 31, 2015 are shown below.
