Fair Value of Financial Instruments

The carrying amounts reported at March 31, 2016 and December 31, 2015 for cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable and accrued liabilities approximate fair value because of the short-term maturity of these instruments and are categorized as Level 1 within the GAAP fair value hierarchy.

The Company has debt with variable and fixed interest rates. The fair value of debt with fixed interest rates was determined using the quoted market prices of debt instruments with similar terms and maturities, which are considered Level 2 inputs. The fair value of debt with variable interest rates was also measured using Level 2 inputs, including good faith estimates of the market value for the particular debt instrument, which represent the amount an independent market participant would provide, based upon market observations and other factors relevant under the circumstances. The carrying value of such debt approximated its estimated fair value at March 31, 2016 and December 31, 2015.

The Company has entered into interest rate swap agreements to manage exposure to fluctuations in interest rates.  Fair value of the interest rate swaps is determined using a pricing model based on published interest rates and other observable market data. The fair value was determined after considering the potential impact of collateralization, adjusted to reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk.  The fair value measurement of interest rate swaps utilizes Level 2 inputs.  At March 31, 2016, the fair value of the interest rate swaps represented a liability of $0.6 million.  Refer to Note 9 for further discussion of the interest rate swap agreements.
