Furthermore, management considers the results of the most recent quantitative impairment test completed for a reporting unit and compares the weighted average cost of capital between the current and prior years for each reporting unit. Under the goodwill quantitative impairment test, the evaluation of impairment involves comparing the current fair value of each reporting unit to its carrying value, including goodwill.

Control is transferred upon delivery of the goods to the customer. Shipping and/or handling costs that occur before the customer obtains control of the goods are deemed to be fulfillment activities and are accounted for as fulfillment costs. We assess the goods and services promised in our customers' purchase orders and identify a performance obligation for each promise to transfer a good or service (or bundle of goods or services) that is distinct. We offer various forms of trade promotions and the methodologies for determining these provisions are dependent on local customer pricing and promotional practices, which range from contractually fixed percentage price reductions to provisions based on actual occurrence or performance. Our promotional activities are conducted either through the retail trade or directly with consumers and include activities such as in-store displays and events, feature price discounts, consumer coupons, and loyalty programs. The costs of these activities are recognized at the time the related revenue is recorded, which normally precedes the actual cash expenditure. The recognition of these costs therefore requires management judgment regarding the volume of promotional offers that will be redeemed by either the retail trade or consumer. These estimates are made using various techniques including historical data on performance of similar promotional programs. Differences between estimated expense and actual redemptions are recognized as a change in management estimate in a subsequent period.
