_______ (a)We expect to reclassify an approximate $116 million gain associated with cash flow hedge price risk management activities included in our accumulated other comprehensive loss balance as of June 30, 2020 into earnings during the next twelve months (when the associated forecasted transactions are also expected to impact earnings); however, actual amounts reclassified into earnings could vary materially as a result of changes in market prices. (b)During the three months ended June 30, 2019, we recognized a $12 million gain associated with a write-down of hedged inventory. All other amounts reclassified were the result of the hedged forecasted transactions actually affecting earnings (i.e., when the forecasted sales and purchases actually occurred). (c)Amounts represent our share of an equity investee’s accumulated other comprehensive income (loss).
