Income Taxes

The effective tax rates were 7.3 percent and 8.6 percent for the three and nine months ended September 30, 2022, respectively, reflecting the favorable tax impact of the implementation of a provision in the Tax Cuts and Jobs Act (2017 Tax Act) that requires capitalization and amortization of research and development expenses for tax purposes starting in 2022, net investment losses on equity securities, and an intangible asset impairment charge. We expect our effective tax rate to be approximately 13 percent to 14 percent for 2022 if the capitalization and amortization of research and development expenses provision of the 2017 Tax Act is deferred or repealed by the U.S. Congress effective for 2022.

The effective tax rate was 10.9 percent for the three months ended September 30, 2021, reflecting the favorable tax impact of a debt extinguishment loss and of net investment losses on equity securities, partially offset by a net discrete tax detriment. The effective tax rate was 10.7 percent for the nine months ended September 30, 2021, reflecting the favorable tax impact of a net discrete tax benefit, a debt extinguishment loss, and a net inventory impairment charge related to our COVID-19 antibodies.

The U.S. examination of tax years 2016-2018 began in the fourth quarter of 2019 and remains ongoing. The resolution of this audit period will likely extend beyond the next 12 months.
