Question: How did Pfizer's total comprehensive income change between the quarters ending June 30, 2024, and July 2, 2023?
Answer: Pfizer’s total comprehensive income for the quarter ending June 30, 2024, was a loss of $17 million, compared to $2,514 million for the quarter ending July 2, 2023. This represents a decline of $2,531 million or 100.68%, indicating a significant downturn in overall income.
Calculation:
Change in comprehensive income = -17 - 2,514 = -2,531 million
Percentage change = (-2,531 / 2,514) * 100 = -100.68%
