Income Taxes	(11) Income Taxes Our effective income tax rates were 26.9% and 23.7% during the three-month periods ended September 30, 2019 and 2018, respectively, and 22.2% and 23.3% during the nine-month periods ended September 30, 2019, and 2018, respectively. The increase in the effective tax rate during the three-month period ended September 30, 2019, as compared to the comparable quarter of 2018, was primarily due to $6 million of tax expense related to non-deductible DOJ Reserve offset by $2 million of tax benefit attributable to employee share-based payments during the third quarter of 2019. The net decrease in the effective tax rate during the nine-month period ended September 30, 2019, compared with the same period in 2018, was primarily due to an $11 million tax benefit attributable to employee share-based payments, a $4 million tax benefit related to the effects of a change in state tax law enacted during 2019 offset by $6 million of tax expense due to non-deductible DOJ Reserve during the third quarter of 2019 as compared to $1 million of tax benefit attributable to employee share-based payments during the first nine months of 2018.
