Revenue from Contract with Customer [Abstract]  
Revenues Revenues
The Company's presentation of revenue by reportable segment most reasonably depicts how the nature, amount, timing and uncertainty of the Company's revenue and cash flows are affected by economic and market-specific factors. The Company recognizes revenues when the requisite performance obligation has been met, that is, when the Company transfers control of its products to customers per the arranged shipping terms, which may be at time of shipment or upon delivery depending on the terms of the underlying contract.
The following represents the Company’s disaggregated revenues:

The process by which the Company recognizes revenues is similar across each of the Company's reportable segments. The Company records estimated reductions in sales for customer rebates and discounts including volume, promotional, cash and other discounts. Rebates and discounts are recorded in Net sales based on management’s best estimate when products are sold. The estimates are based on historical experience for similar programs and products, and contractual obligations. Management reviews these rebates and discounts on an ongoing basis and the related accruals are adjusted, if necessary, as additional information becomes available.
