Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer [Text Block]

REVENUE

The Corporation recognizes revenue when control of a promised good and/or service is transferred to a customer in an amount that reflects the consideration that the Corporation expects to be entitled to in exchange for that good and/or service.

Performance Obligations

The Corporation identifies a performance obligation for each promise in a contract to transfer a distinct good or service to the customer. As part of its assessment, the Corporation considers all goods and/or services promised in the contract, regardless of whether they are explicitly stated or implied by customary business practices. The Corporation’s contracts may contain either a single performance obligation, including the promise to transfer individual goods or services that are not separately distinct within the context of the respective contracts, or multiple performance obligations. For contracts with multiple performance obligations, the Corporation allocates the overall transaction price to each performance obligation using standalone selling prices, where available, or utilizes estimates for each distinct good or service in the contract where standalone prices are not available.

The Corporation’s performance obligations are satisfied either at a point-in-time or on an over-time basis. Revenue recognized on an over-time basis for the three months and nine months ended September 30, 2019 accounted for approximately 47% and 48%, respectively, of total net sales. Revenue recognized on an over-time basis for the three months and nine months ended September 30, 2018 accounted for approximately 49% and 46%, respectively, of total net sales. Typically, over-time revenue recognition is based on the utilization of an input measure used to measure progress, such as costs incurred to date relative to total estimated costs. Revenue recognized at a point-in-time for the three months and nine months ended September 30, 2019 accounted for approximately 53% and 52%, respectively, of total net sales. Revenue recognized at a point-in-time for the three months and nine months ended September 30, 2018 accounted for approximately 51% and 54%, respectively, of total net sales. Revenue for these types of arrangements is recognized at the point in time in which control is transferred to the customer, typically based upon the terms of delivery.

Contract backlog represents the remaining performance obligations that have not yet been recognized as revenue. Backlog includes deferred revenue and amounts that will be invoiced and recognized as revenue in future periods. Total backlog was approximately $2.2 billion as of September 30, 2019, of which the Corporation expects to recognize approximately 92% as net sales over the next 12-36 months. The remainder will be recognized thereafter.

Contract Balances

Timing of revenue recognition and cash collection may result in billed receivables, unbilled receivables (contract assets), and deferred revenue (contract liabilities) on the Condensed Consolidated Balance Sheet. The Corporation’s contract assets primarily relate to its rights to consideration for work completed but not billed as of the reporting date. Contract assets are

transferred to billed receivables when the rights to consideration become unconditional. This is typical in situations where amounts are billed as work progresses in accordance with agreed-upon contractual terms or upon achievement of contractual milestones. The Corporation’s contract liabilities primarily consist of customer advances received prior to revenue being earned. Revenue recognized during the three and nine months ended September 30, 2019 and 2018 included in the contract liabilities balance at the beginning of the year was approximately $26 million and $159 million, respectively, and $30 million and $144 million, respectively. Contract assets and contract liabilities are reported in the "Receivables, net" and "Deferred revenue" lines, respectively, within the Condensed Consolidated Balance Sheet.
