The Company is operated and managed geographically and has production facilities in the United States, Mexico and China. The Company utilizes reportable segment’s site contribution (site revenues minus operating expenses, excluding unrealized foreign exchange gain (loss) on unsettled forward exchange contracts, corporate allocations and restructuring expenses) to monitor reportable segment performance. Site contribution is utilized by the chief operating decision-maker as the indicator of reportable segment performance, as it reflects costs which our operating site management is directly responsible for. Intersegment adjustments reflect intersegment sales that are generally recorded at prices that approximate arm’s-length transactions. In assessing the performance of the reportable segments, management attributes site revenue to the reportable segment that ships the product to the customer, irrespective of the product’s destination. Information about the reportable segments is as follows:

Sales of the Company’s products are concentrated in certain cases among specific customers in the same industry. The Company is subject to concentrations of credit risk in trade receivables. The Company considers concentrations of credit risk in establishing the allowance for doubtful accounts and believes the recorded allowances are adequate.

 

The Company expects to continue to depend upon a relatively small number of customers for a significant percentage of its revenue. In addition to having a limited number of customers, the Company manufactures a limited number of products for each customer. If the Company loses any of its larger customers or any product line manufactured for of its larger customers, it could experience a significant reduction in revenue. Also, the insolvency of or more of its larger customers or the inability of or more of its larger customers to pay for its orders could decrease revenue. As many costs and operating expenses are relatively fixed, a reduction in net revenue can decrease profit margins and adversely affect the business, financial condition and results of operations.
