The effective tax rate of 22.5% for the six months ended June 30, 2020 reflects a benefit of $14 million of discrete items associated with PPG's U.S. and foreign jurisdictions. Income tax expense for the first six months of 2020 is based on an estimated annual effective rate, which requires management to make its best estimate of annual pretax income or loss. Income tax expense for the six months ended June 30, 2019 reflects $3 million for discrete items associated with PPG's U.S. and foreign locations and implementation of updated regulations associated with the 2017 Tax Cuts and Jobs Act for Global Intangible Low Taxed Income.
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 2020 pretax results for U.S. and foreign income or loss vary from estimates, the actual Income tax expense recognized in 2020 could be different from the forecasted amount used to estimate the Income tax expense for the six months ended June 30, 2020.
