Revenue from Contract with Customer [Abstract] |
Revenue from Contract with Customer [Policy Text Block] | Accounting Policies - Many of the contract types described within Note A of the Notes to Consolidated Financial Statement in our Annual Report contain additional fees or charges payable by customers for nonperformance (e.g., minimum volume commitments or product specifications), which are considered to be variable consideration. These fees and charges are not recorded until it is probable that a significant reversal of the associated revenue will not occur.
