(million) (c) What cumulative effect has ITW's choice of LIFO over FIFO had on its pretax income as of year end 2018? OThe cumulative effect is that pretax income has decreased. LIFO matches more "current" inventory costs against current selling prices, thus avoiding the recognition of holding gains. OThe cumulative effect is that pretax income has not changed. LIFO and FIFO are simply two different ways to account for inventories. Both methods lead to the same pretax income. OThe cumulative effect on pretax income is nonexistent. The LIFO and FIFO methods of inventory accounting cause only cash flow effects, and they do not affect pretax income. OThe cumulative effect is that pretax income has increased. LIFO matches more "current" inventory costs against current selling prices, thus avoiding the recognition of holding gains.
