Fair Value Measurement

Fair value accounting standards describe three levels that may be used to measure fair value:


•	Level 1 - Quoted prices in active markets for identical assets or liabilities.


•	Level 2 - Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.


•	Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The following tables summarize significant assets and liabilities measured at fair value in the condensed consolidated balance sheets on a recurring basis for each of the fair value levels (in thousands):



	Fair Value Measurement at Reporting Date Using

Cash equivalents
Money market funds	$	50,148	$	—	$	—	$	50,148

Total assets	$	113,220	$	—	$	—	$	113,220

A reconciliation of cash equivalents to consolidated cash and cash equivalents is as follows:



(in thousands)	September 30, 2014		December 31, 2013		September 30, 2013
Cash equivalents	$	50,148	$	89,336	$	113,220
Cash	117,026		139,785		99,243
Total cash and cash equivalents	$	167,174	$	229,121	$	212,463

The carrying values and estimated fair values of our financial instruments that are not required to be recorded at fair value in the condensed consolidated balance sheets are as follows:



		September 30, 2014				December 31, 2013				September 30, 2013
(in thousands)	Fair Value Hierarchy	Carrying Value		Fair Value		Carrying Value		Fair Value		Carrying Value		Fair Value
Assets:
Held-to-maturity marketable securities¹	Level 1	$	102,090	$	101,711	$	117,202	$	116,915	$	86,906	$	86,594
Liabilities (including current maturities):
Senior notes payable²	Level 3	$	200,000	$	225,186	$	200,000	$	225,865	$	200,000	$	226,110
Credit Agreement loan²	Level 3	70,000		70,258		70,000		69,601		70,000		70,166

¹Held-to-maturity marketable securities are periodically assessed for other-than-temporary impairment.

²The fair values of the senior notes payable and Credit Agreement (defined in Note 11) loan are based on borrowing rates available to us for long-term loans with similar terms, average maturities, and credit risk.

The carrying values of receivables, other current assets, and accrued expenses and other current liabilities approximate their fair values due to the short-term nature of these instruments. In addition, the fair value of non-recourse debt measured using Level 3 inputs approximates its carrying value due to its relative short-term nature and competitive interest rates. During the three and nine months ended September 30, 2014 and 2013, we did not record any fair value adjustments related to nonfinancial assets and liabilities measured at fair value on a nonrecurring basis.

In March 2014, we entered into an interest rate swap with a notional amount of $100.0 million which matures in June 2018 to convert the interest rate of our 2019 Notes (defined in Note 11) from a fixed rate of 6.11% to a floating rate of 4.15% plus six-month LIBOR. The interest rate swap is reported at fair value using Level 2 inputs, and gains or losses are recorded in other income (expense), net in our condensed consolidated statement of operations and were losses of $0.6 million and gains of $0.3 million during the three and nine months ended September 30, 2014, respectively.

In March 2014, we entered into two diesel commodity swaps covering May to October, 2014 and 2015 which represented roughly 25% of our forecasted purchase for diesel. In May 2014, we entered into two natural gas commodity swaps covering June to October 2014 and May to October 2015 representing roughly 25% of our forecasted purchase of natural gas. The commodity swaps are reported at fair value using Level 2 inputs, and gains or losses are recorded in other income (expense), net in our condensed consolidated statement of operations and were losses of $0.6 million and $0.7 million during the three and nine months ended September 30, 2014, respectively.
