	Six Months Ended June 30
	2022		2021
Effective tax rate on pretax income	26.9	%	25.1	%

The effective tax rate of 26.9% for the six months ended June 30, 2022 reflects a tax benefit of $27 million on the $230 million Impairment and other related (income)/charges, net associated with PPG’s operations in Russia. Income tax expense for the six months ended June 30, 2021 includes expense of $15 million for discrete items associated with PPG's U.S. and foreign jurisdictions.

Income tax expense for the six months ended June 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 the Income tax expense for the six months ended June 30, 2022.
