Risks and Uncertainties [Abstract]
Market Concentrations and Risks	Note 22: Market Concentrations and Risks Concentrations of Credit We sell our products to many customers in several markets across multiple geographic areas. The ten largest customers, of which six are distributors, constitute in aggregate approximately 33%, 36%, and 34% of revenues in 2014, 2013, and 2012, respectively. Unconditional Commodity Purchase Obligations At December 31, 2014, we were committed to purchase approximately 1.5 million pounds of copper at an aggregate fixed cost of $4.6 million. At December 31, 2014, this fixed cost was $0.2 million more than the market cost that would be incurred on a spot purchase of the same amount of copper. The aggregate market cost was based on the current market price of copper obtained from the New York Mercantile Exchange. In addition, at December 31, 2014, we were committed to purchase 0.7 million pounds of aluminum at an aggregate fixed cost of $0.8 million. At December 31, 2014, this fixed cost approximated the market cost that would be incurred on a spot purchase of the same amount of aluminum. These commitments will mature in 2015. Labor Approximately 23% of our labor force is covered by collective bargaining agreements at various locations around the world. Approximately 19% of our labor force is covered by collective bargaining agreements that we expect to renegotiate during 2015. Fair Value of Financial Instruments Our financial instruments consist primarily of cash and cash equivalents, trade receivables, trade payables, and debt instruments. The carrying amounts of cash and cash equivalents, trade receivables, and trade payables at December 31, 2014 are considered representative of their respective fair values. The carrying amount of our debt instruments at December 31, 2014 and 2013 was $1,767.9 million and $1,367.0 million, respectively. The fair value of our senior subordinated notes at December 31, 2014 and 2013 was approximately $1,529.4 million and $1,098.6 million, respectively, based on quoted prices of the debt instruments in inactive markets (Level 2 valuation). This amount represents the fair values of our senior subordinated notes with a carrying value of $1,521.5 million and $1,118.3 million as of December 31, 2014 and 2013, respectively. We believe the fair value of our Term Loan approximates book value.
