Adoption of New Accounting Standards: In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, which requires that an entity measure impairment of certain financial instruments, including trade receivables, based on expected losses rather than incurred losses. We adopted ASU 2016-13 on January 1, 2020. The adoption of this new standard resulted in the recognition of $1 million of incremental bad debt expense in the nine months ended September 30, 2020.
