We are subject to U.S. federal, state and international income taxes. We are generally no longer subject to federal, state, or international income tax examinations by tax authorities for years before 2018 with a few exceptions. Due to the potential for resolution of state and foreign examinations, and the expiration of various statutes of limitations, it is reasonably possible that our gross unrecognized tax benefit balance may change within the next twelve months by a range of $0 to $6.3 million.
 
Effective Tax Rate
Our effective income tax rate was 23.9% for the three months ended June 30, 2022, compared to 22.1% for the three months ended June 30, 2021. Our effective income tax rate was 25.4% for the six months ended June 30, 2022, compared to 23.2% for the six months ended June 30, 2021. Our effective tax rate was higher for the second quarter and first six months of 2022 as compared to 2021 due to a greater foreign income tax rate differential. The increase in the foreign rate differential was primarily driven by the adjustment to fully impair our investment in Russia.
