Risks and Uncertainties [Abstract]
Concentration Risk Disclosure [Text Block]	Risk Management We are subject to various risks and uncertainties in the ordinary course of business due, in part, to the competitive global nature of the industry in which we operate, changing commodity prices for the materials used in the manufacture of our products and the development of new products. The functional currency of certain foreign operations in Mexico is the Mexican peso. The settlement of accounts receivable and accounts payable for our operations in Mexico requires the transfer of funds denominated in the Mexican peso, the value of which decreased 2 percent in relation to the U.S. dollar in the first quarter of 2016. Foreign exchange gains totaled $0.2 million in the first quarter of 2016 and foreign exchange losses totaled $0.2 million in the first quarter of 2015. All transaction gains and losses are included in other income (expense) in the condensed consolidated statements of operations. As it relates to foreign currency translation gains and losses, however, since 1990, the Mexican peso has experienced periods of relative stability followed by periods of major declines in value. The impact of these changes in value relative to our Mexico operations resulted in a cumulative unrealized translation loss at March 27, 2016 of $90.1 million. Translation gains and losses are included in other comprehensive income in the condensed consolidated statements of comprehensive income (loss). When market conditions warrant, we may also enter into purchase commitments to secure the supply of certain commodities used in the manufacture of our products, such as aluminum, natural gas and other raw materials. At March 27, 2016 we did not have any purchase commitments in place for the delivery of aluminum, natural gas or other raw materials in 2016.

Risk Management

We are subject to various risks and uncertainties in the ordinary course of business due, in part, to the competitive global nature of the industry in which we operate, changing commodity prices for the materials used in the manufacture of our products and the development of new products.

The functional currency of certain foreign operations in Mexico is the Mexican peso. The settlement of accounts receivable and accounts payable for our operations in Mexico requires the transfer of funds denominated in the Mexican peso, the value of which decreased 2 percent in relation to the U.S. dollar in the first quarter of 2016. Foreign exchange gains totaled $0.2 million in the first quarter of 2016 and foreign exchange losses totaled $0.2 million in the first quarter of 2015. All transaction gains and losses are included in other income (expense) in the condensed consolidated statements of operations.

As it relates to foreign currency translation gains and losses, however, since 1990, the Mexican peso has experienced periods of relative stability followed by periods of major declines in value. The impact of these changes in value relative to our Mexico operations resulted in a cumulative unrealized translation loss at March 27, 2016 of $90.1 million. Translation gains and losses are included in other comprehensive income in the condensed consolidated statements of comprehensive income (loss).

When market conditions warrant, we may also enter into purchase commitments to secure the supply of certain commodities used in the manufacture of our products, such as aluminum, natural gas and other raw materials. At March 27, 2016 we did not have any purchase commitments in place for the delivery of aluminum, natural gas or other raw materials in 2016.
