(a) 
Amounts do not include foreign currency translation adjustments attributable to noncontrolling interests of $11 million loss in 2019, $20 million loss in 2018 and $14 million income in 2017. Amounts in 2019 include after-tax gains of approximately $978 million related to foreign currency translation adjustments attributable to our equity method investment in GSK Consumer Healthcare (see Note 2C), partially offset by the strengthening of the U.S. dollar against the euro and the Australian dollar, and the results of our net investment hedging program.
(b) 
Amounts represent the cumulative effect adjustments as of January 1, 2018 from the adoption of new accounting standards related to (i) financial assets and liabilities and (ii) the reclassification of certain tax effects from AOCI. For additional information, see Notes to Consolidated Financial Statements––Note 1B. Basis of Presentation and Significant Accounting Policies: Adoption of New Accounting Standards in 2018 in our 2018 Financial Report.
