The Company recognizes revenue when persuasive evidence of an arrangement exists, product has been delivered or services have been rendered, the price is fixed or determinable and collectability is reasonably assured. Revenue as reflected in the accompanying consolidated statements of operations is net of estimated sales returns and allowances.
The Company's customer sales return policy generally allows customers to return products only if the products can be resold at full value or returned to suppliers for full credit. The Company records an accrual for estimated customer sales returns at the time of sale to the customer. At September 30, 2013 and 2012, the Company's accrual for estimated customer sales returns was $275.8 million and $252.5 million, respectively.
The Company reports the gross dollar amount of bulk deliveries to customer warehouses in revenue and the related costs in cost of goods sold. Bulk delivery transactions are arranged by the Company at the express direction of the customer, and involve either drop shipments from the supplier directly to customers' warehouse sites or cross-dock shipments from the supplier to the Company for immediate shipment to the customers' warehouse sites. The Company is a principal to these transactions because it is the primary obligor and has the ultimate and contractual responsibility for fulfillment and acceptability of the products purchased, and bears full risk of delivery and loss for products, whether the products are drop-shipped or shipped via cross-dock. The Company also bears full credit risk associated with the creditworthiness of any bulk delivery customer. As a result, the Company records bulk deliveries to customer warehouses as gross revenues. Gross profit earned by the Company on bulk deliveries was not material in any year presented.
