Our reserve requirements are based on the best information available to us and are reevaluated and adjusted as additional information is received. Our reserves are also based on amounts determined by using percentages applied to certain aged receivable categories. These percentages are determined by a variety of factors including, but <em style="font: inherit;">not</em> limited to, current economic trends, historical payment and bad debt write-off experience.

Our reserve requirements are based on the best information available to us and are reevaluated and adjusted as additional information is received.

These percentages are determined by a variety of factors including, but <em style="font: inherit;">not</em> limited to, current economic trends, historical payment and bad debt write-off experience.

Although we believe there are multiple sources of supply from other contract manufacturers as well as multiple suppliers of component parts required by the contract manufacturers, a disruption of supply of component parts or completed products, even if short term, would have a material negative impact on our revenues.
