Market Concentrations and Risks | 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 35%, 33%, and 33% of revenues in 2017, 2016, and 2015, respectively. Unconditional Commodity Purchase Obligations At December 31, 2017, we were committed to purchase approximately 2.3 million pounds of copper at an aggregate fixed cost of $7.0 million. At December 31, 2017, this fixed cost was $0.5 million less 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. Labor Approximately 21% of our labor force is covered by collective bargaining agreements at various locations around the world. Approximately 16% of our labor force is covered by collective bargaining agreements that we expect to renegotiate during 2018. 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, 2017 are considered representative of their respective fair values. The fair value of our senior subordinated notes at December 31, 2017 and 2016 was approximately $1,619.3 million and $1,693.2 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 $1,584.2 million and $1,643.4 million as of December 31, 2017 and 2016, respectively.
