The Company enters into derivative contracts with high-quality financial institutions and limits the amount of credit exposure to any counterparty. The Company’s foreign currency forward contracts do not contain any credit-risk-related contingent features. In addition, the derivative contracts typically mature in less than six months and the Company continuously evaluates the credit standing of its counterparty financial institutions. The counterparties to these arrangements are large highly rated financial institutions and the Company does not consider non-performance a material risk. The Company believes the counterparties for its outstanding contracts are large, financially sound institutions and thus, the Company does not anticipate nonperformance by these counterparties. </span></div>The Company’s customers are primarily retailers and wholesale distributors who sell or distribute the products to a large group of end-users. The Company regularly performs credit evaluations of the Company’s customers’ financial condition and performance and considers factors such as historical experience, credit quality, age of the accounts receivable balances, geographic or country-specific risks and current economic conditions that may affect customers’ ability to pay. The Company does not require collateral from its customers. Historically, a substantial portion of the Company’s revenue has been derived from a limited number of retailers and wholesale distribution partners.
