Revenue Recognition [Abstract] |
Revenue Recognition | Revenue Recognition The Company recognizes revenue on sales when products are shipped and the customer takes ownership and assumes risk of loss. Certain customers may be required to prepay prior to shipment in order to maintain payment protection related to certain foreign and domestic sales. These amounts are recorded as unearned revenue and recognized when the products have shipped and the customer takes ownership and assumes risk of loss. The Company has formula arrangements with certain suppliers whereby the charge or credit for raw materials is tied to published finished product commodity prices after deducting a fixed processing fee incorporated into the formula and is recorded as a cost of sale by line of business. The Company recognizes revenue related to grease trap servicing in the month the trap service occurs.
