(a) Effective January 1, 2020, we adopted, using the modified retrospective adoption approach, an accounting standards update with new guidance relating to credit losses on financial instruments.  Our adoption of this standards update resulted in a cumulative effect adjustment to decrease Retained Earnings by $12 million, with Accounts Receivables decreasing by $15 million and Deferred Income Taxes increasing by $3 million.  Periods prior to 2020 have not been restated for the adoption of this standards update.

(b) Accounts receivable charged off.
