Revenue from Contract with Customer [Abstract]

Revenue Recognition

Revenue RecognitionThe FASB issued Revenue from Contracts with Customers (Topic 606) superseding virtually all existing revenue recognition guidance. We adopted this new standard in the first quarter of 2018 using the modified retrospective approach. We applied the new standard to all contracts that were not completed as of January 1, 2018 and reflected the aggregate effect of all modifications in determining and allocating the transaction price. The cumulative effect of adoption of $8 million did not have a material impact on our consolidated financial statements.

The following table shows revenue disaggregated by operating area and product type, for the years ended December 31, 2019 and 2018:
