During 2019 (its first year of operations) and 2020, Fieri Foods used the FIFO inventory costing method for both financial reporting and tax purposes. At the beginning of 2021, Fieri decided to change to the average method for both financial reporting and tax purposes. Income components before income tax for 2019, 2020, and 2021 were as follows: ($ in millions) 2019 2020 2021 Revenues $ 490 $ 500 $ 530 Cost of goods sold (FIFO) (49 ) (51 ) (57 ) Cost of goods sold (average) (74 ) (78 ) (84 ) Operating expenses (286 ) (294 ) (298 ) Dividends of $30 million were paid each year. Fieris fiscal year ends December 31.
