	Nine Months Ended September 30
	2022		2021
Effective tax rate on pretax income	23.7	%	24.1	%

The effective tax rate of 23.7% for the nine months ended September 30, 2022 reflects a tax benefit of $27 million on the $230 million net charges associated with PPG’s operations in Russia. In the second quarter 2021, PPG recorded a net tax charge of $22 million as a result of new legislation enacted in June 2021 that increased the United Kingdom's corporation tax rate.

Income tax expense for the nine months ended September 30, 2022 and 2021 is based on an estimated annual effective rate, which requires management to make its best estimate of annual pretax income or loss. During the year, PPG management regularly updates forecasted annual pretax results for the various countries in which PPG operates based on changes in factors such as prices, shipments, product mix, raw material inflation and manufacturing operations. To the extent that actual 2022 pretax results for U.S. and foreign income or loss vary from estimates, the actual Income tax expense recognized in 2022 could be different from the forecasted amount used to estimate Income tax expense for the nine months ended September 30, 2022.
