(1)The amount reported within purchases, sales and settlements is the purchase price (for purchases) and the sales/settlement proceeds (for sales and settlements) based upon the actual date purchased or sold/settled. Items purchased and sold/settled in the same period are excluded from the rollforward. The Company had no issuances during the period.
Financial Instruments Carrying Amounts And Estimated Fair Value [Table Text Block] | The following table presents the carrying values and estimated fair values of the Company’s financial instruments, which were not measured at fair value on a recurring basis, as of June 30, 2021 and December 31, 2020 (dollars in millions). For additional information regarding the methods and significant assumptions used by the Company to estimate these fair values, see Note 6 – “Fair Value of Assets and Liabilities” in the Notes to Consolidated Financial Statements included in the Company’s 2020 Annual Report. This table excludes any payables or receivables for collateral under repurchase or reverse repurchase agreements and other transactions. The estimated fair value of the excluded amount approximates carrying value as they equal the amount of cash collateral received/paid.
