Fair Value Measurements

12 Months Ended

Dec. 31, 2014

The three-tier value hierarchy the Company utilizes, which prioritizes the inputs used in the valuation methodologies, is:

Level 1—Valuations based on quoted prices for identical assets and liabilities in active markets.

Level 2—Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

Level 3—Valuations based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants.

The fair value of cash, accounts receivable and accounts payable approximate their carrying values. The fair value of cash equivalents are determined using the fair value hierarchy described above. Cash equivalents consisting of money market funds are valued based on quoted prices in active markets and as a result are classified as Level 1.

The Company’s pension plan asset portfolio as of December 31, 2014 and 2013 is primarily invested in fixed income securities, which generally fall within Level 2 of the fair value hierarchy. Fixed income securities in the pension plan asset portfolio are valued based on evaluated prices provided to the trustee by independent pricing services. Such prices may be determined by factors which include, but are not limited to, market quotations, yields, maturities, call features, ratings, institutional size trading in similar groups of securities and developments related to specific securities. Refer to Note 5 for pension fair value disclosures.

Fair Value Measurements of Debt

The fair value of the Company’s Senior Secured Notes as of December 31, 2014 was estimated to be $216,808 compared to a carrying value of $210,000. The fair value for the Senior Secured Notes is determined based on recent trades of the bonds and fall within Level 2 of the fair value hierarchy.

The fair value of the Convertible Notes, as of December 31, 2014 was estimated to be approximately $61,932 compared to a carrying value of $57,500. The fair value for the Convertible Notes, which fall within Level 3 of the fair value hierarchy, is determined based on similar debt instruments that do not contain a conversion feature, as well as other factors related to the callable nature of the notes.

The main inputs and assumptions into the fair value model for the Convertible Notes at December 31, 2014 were as follows:



Company's stock price at the end of the period	$	7.98
Expected volatility	38.3		%
Credit spreads	9.28		%
Risk-free interest rate	1.08		%

As of December 31, 2014, the estimated fair value of the Company's debt outstanding under its revolving credit facility, which falls within Level 3 of the fair value hierarchy, was $51,253 compared to its carrying value of $59,200. The fair value was calculated based on the present value of the outstanding debt using the revolving credit facility interest rate as of December 31, 2014 plus a premium and assuming the current amount of debt outstanding as of December 31, 2014 was outstanding until the maturity of the Company's facility in December 2019. Although borrowings could be materially greater or less than the current amount of borrowings outstanding at the end of the period, it is not practical to estimate the amounts that may be outstanding during the future periods since there is no predetermined borrowing or repayment schedule.

Fair Value Measurements of Commodity Hedges

The Company has a commodity hedging program to mitigate risks associated with certain commodity price fluctuations. At December 31, 2014, the Company had executed forward contracts that extend through 2016. The counterparty to these contracts is not considered a credit risk by the Company. At December 31, 2014 and 2013, the notional value associated with forward contracts was $7,486 and $12,492, respectively. The Company recorded, through cost of materials, realized and unrealized net losses of $288, $2,141 and $430 during the years ended December 31, 2014, 2013 and 2012, respectively, as a result of the decline in the fair value of the contracts. As of December 31, 2014 and 2013, all commodity hedge contracts were in a liability position. Refer to Note 12 - Commitments and Contingent Liabilities for letters of credit outstanding for collateral associated with commodity hedges.

The Company uses information which is representative of readily observable market data when valuing derivative liabilities associated with commodity hedges. The derivative liabilities are classified as Level 2 in the table below.

The liabilities measured at fair value on a recurring basis were as follows:



	Level 1		Level 2		Level 3		Total ^(a)
As of December 31, 2014
Derivative liability for commodity hedges	$	—	$	1,615	$	—	$	1,615
As of December 31, 2013
Derivative liability for commodity hedges	$	—	$	2,871	$	—	$	2,871

^(a)As of December 31, 2014, the short-term portion of the derivative liability for commodity hedges of $1,137 is included in "Accrued and other liabilities" and the long-term portion of $478 is included in "Other non-current liabilities" in the Consolidated Balance Sheet. As of December 31, 2013, the short-term portion of the derivative liability for commodity hedges of $1,516 is included in "Accrued and other liabilities" and the long-term portion of $1,355 is included in "Other non-current liabilities" in the Consolidated Balance Sheet.
