Accounting Changes and Error Corrections [Abstract]
New accounting pronouncements	New accounting pronouncementsIn June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, "Measurement of Credit Losses on Financial Instruments." ASU 2016-13 requires a financial asset (or a group of financial assets) measured at amortized cost to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. Credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses. We adopted ASU 2016-13 on July 1, 2020. The adoption of this guidance, using the modified retrospective method, did not result in a cumulative-effect adjustment to retained earnings and did not have a material impact on the consolidated financial statements or related disclosures.
