The Company recognizes shipping and handling activities that occur after the customer has obtained control of goods as a fulfillment cost rather than as an additional promised service. Therefore, the Company recognizes revenue and accrues the shipping and handling costs when the control of goods transfers to the customer upon shipment. Advertising costs.
