Financial Instruments-Credit Losses
January 1, 2020

Modified Retrospective
The new standard requires the measurement and recognition of expected credit losses using the current expected credit loss model for financial assets held at amortized cost, which includes the Company’s trade accounts receivable, certain financial instruments and contract assets. It replaces the existing incurred loss impairment model with an expected loss methodology. The recorded credit losses are adjusted each period for changes in expected lifetime credit losses. The standard requires a cumulative effect adjustment to the statement of financial position as of the beginning of the first reporting period in which the guidance is effective.
As a result of the adoption, we recorded an increase to our opening retained earnings and "Trade accounts receivable, net" of $1 million each.

Prior period amounts are not adjusted and continue to be reported in accordance with our historical accounting policies.
