Note

We recognize revenue from our products when the products are shipped to our customers. Repair and maintenance equipment service revenue is recorded when it is performed provided the customer terms are that the customer is to be charged on a time and material basis or on a straight-line basis over the term of the contract when the customer has signed a service contract. Revenue is recognized only where persuasive evidence of an arrangement exists, our price is fixed or estimable and collectability is reasonably assured. We record offsets to revenue for allowances, end-user pricing adjustments, trade spending, coupon redemption costs and returned product. Customers generally do

not

have the right to return product unless it is damaged or defective. We provide an allowance for doubtful receivables after taking into consideration historical experience and other factors. The allowance for doubtful receivables was
