Foreign Operations

In conjunction with the Company's acquisition of certain assets of Airshield Corporation on October 16, 2001, the Company established manufacturing operations in Mexico (under the Maquiladora program). The Mexican operation is a captive manufacturing facility of the Company and the functional currency is United States dollars. Essentially all sales of the Mexican operations are made in United States dollars, which totaled $74,667,000 in 2012 and $68,008,000 in 2011. Expenses are incurred in the United States dollar and the Mexican peso. Expenses incurred in pesos include labor, utilities, supplies and materials, and amounted to approximately 20% of sales of the Matamoros facility in 2012 and 23% of sales of the Matamoros facility in 2011. The Company's manufacturing operation in Mexico is subject to various political, economic, and other risks and uncertainties including safety and security concerns inherent to Mexico. Among other risks, the Company's Mexican operations are subject to domestic and international customs and tariffs, changing taxation policies, and governmental regulations.
