Note 6. Fair Value of Financial Instruments

Fair value of financial and non-financial assets and liabilities is the price that would be received for an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants. The three levels of the fair value hierarchy for assessing the inputs used in fair value measurements are as follows:

·Level 1 – quoted prices in active markets for identical assets and liabilities
·Level 2 – observable inputs other than quoted prices in active markets for identical assets and liabilities
·Level 3 – unobservable inputs in which there is little or no market data available and require the entity to develop its own assumptions

The highest priority is given to quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest priority is given to unobservable inputs (Level 3).

The carrying value of cash and cash equivalents, net accounts receivables, payables, and other short-term monetary assets and liabilities was estimated by management to approximate fair value due to the relatively short period of time to maturity for these instruments.

Our long-term debt credit agreement allows us to select short-term LIBOR pricing options, which we have elected. Therefore, the carrying amounts of our long-term debt approximate its fair value. The fair value estimate of our interest rate swaps represent the net present value of future cash flows based on projections of the three-month LIBOR rate over the life of each swap. It also incorporates credit valuation adjustments to appropriately reflect both our own non-performance risk and the non-performance risk of the respective counterparties. See Note 8 "Financial Derivative Instruments" for further discussion regarding our interest rate swaps.

The fair value and carrying value of our investments, long-term debt, after deducting current maturities, and our interest rate swaps are as follows at June 30, 2013 and December 31, 2012:
