Revenue From Contract With Customer [Abstract]
Description of adoption of new accounting pronouncement	Effective February 4, 2018, we adopted Revenue from Contracts with Customers (ASC Topic 606) as required. We adopted the new standard using the full retrospective method. The standard eliminated the transaction and industry specific revenue recognition guidance under prior U.S. GAAP and replaced it with a principles-based approach for revenue recognition and disclosures. Under the standard, revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services.
Sales recorded as commission	$ 0
Liabilities for performance obligations	$ 337	$ 422	$ 335
