Revenue for product sales is recognized when control of the promised products is transferred to our customers, and we expect to be entitled to consideration in exchange for transferring those products. We account for a contract when a customer provides us with a firm purchase order that identifies the products to be provided, the payment terms for those services, and when collectability of the consideration due is probable.</span></div><div style="line-height:120%;padding-top:12px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div>
