Revenue Recognition Revenue is recognized when there is evidence of an arrangement, the price is fixed or determinable, collection from the customer is probable and either an application service has been provided or, in certain arrangements, risk and title to product have been transferred to the customer, and usually occurs when the application occurs or at the time of shipment, respectively. The Companys standard terms of delivery are included in its contracts of sale, order confirmation documents and invoices. Sales are recorded net of provisions for customer discounts and rebate programs. In an effort to maintain a competitive position in the marketplace and to promote sales and customer loyalty, the Company maintains various rebate and customer loyalty programs with our customers. Depending on the program, the customer may elect to receive either a credit against their account or a cash payment. We recognize an accrued provision for estimated rebates and customer loyalty program payouts at the time services are provided. The primary factors we consider when estimating the provision for rebates and customer loyalty programs are the average historical experience of aggregate credits issued, the historical relationship of rebates as a percentage of total gross product sales, and the contract terms and conditions of the various rebate programs in effect at the time services are performed. We also monitor aggregate actual rebates granted and customer loyalty agreements and compare them to the estimated aggregate provision for rebates to assess the reasonableness of the aggregate rebate reserve at each balance sheet date.
