Revenue from Contract with Customer [Abstract]
Revenue recognition, policy	Revenue is recognized when obligations under the terms of a contract with a customer are satisfied, which occurs at a point in time, upon either shipment or delivery to the customer. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods, which includes estimates for variable consideration. Variable consideration includes trade discounts, rebates, volume-based incentives, cooperative advertising and product returns, which are offered within contracts between the Company and its customers, employing the practical expedient for contract costs. Incidental items that are immaterial to the context of the contract are recognized as expense at the transaction date.
Revenue recognition, variable consideration, policy	Variable Consideration Trade discounts and rebates The Company provides customers with discounts and rebates that are explicitly stated in the Company’s contracts and are recorded as a reduction of revenue in the period the product revenue is recognized. The cost of these incentives is estimated using a number of factors, including historical utilization and redemption rates. The Company includes incentives offered in the form of free products in the determination of cost of sales. Volume based incentives Volume-based incentives involve rebates or refunds of cash that are redeemable only if the customer completes a specified number of sales transactions. Under these incentive programs, the Company estimates the anticipated rebate to be paid and allocates a portion of the estimated cost of the rebate to each underlying sales transaction with the customer. Cooperative advertising Under cooperative advertising arrangements, the Company agrees to reimburse the retailer for a portion of the costs incurred by the retailer to advertise and promote certain of the Company’s products. The Company recognizes the cost of cooperative advertising programs in the period in which the advertising and promotional activity takes place. Product returns The Company generally offers customers a limited right of return for a purchased product. The Company estimates the amount of its product sales that may be returned by its customers and records this as a reduction of revenue in the period the related product revenue is recognized. For all variable consideration, where appropriate, the Company estimates the amount using the expected value, which takes into consideration historical experience, current contractual requirements, specific known market events and forecasted customer buying and payment patterns. Overall, these reserves reflect the Company’s best estimates of the amount of consideration to which the customer is entitled based on the terms of the contracts.
