(1)    Due to fluctuation of the Mexican peso against the U.S. dollar. We record income tax expense (benefit) from the transactional effects of foreign currency and inflation because of appreciation (depreciation) of the Mexican peso. In 2021 and 2020, we also recognized gains (losses) in Other Income (Expense), Net, on the Consolidated Statements of Operations from foreign currency derivatives that were partially hedging Sempra Infrastructure’s exposure to movements in the Mexican peso from its controlling interest in IEnova.
(2)    Related to operations in Mexico.
