An item that would not be accounted for under current GAAP as a change in estimate would be

A) an increase in the expected life of a piece of manufacturing equipment
B) a decrease in the estimated residual value of a delivery van
C) a change from FIFO to LIFO for a small subsidiary
D) an increase in defective items for the best selling video game

A change from FIFO to LIFO for a small subsidiary is considered a change in accounting principle, not a change in estimate. Changes in estimates, such as adjustments to the useful life of equipment, residual values, or estimates of defective items, are accounted for prospectively. However, changes in accounting principles require retrospective application unless it is impractical to determine the cumulative effect of the change.
