Question The adjustments related to changes in the estimated residual value of a long-lived asset should be:

选项：

A.handled prospectively.

B.shown separately on the income statement.

C.handled retrospectively unless impractical to do so.

解释：

1. Correct because in contrast to changes in accounting policies (such as whether to expense the cost of employee stock options), companies sometimes make changes in accounting estimates (such as the useful life of a depreciable asset). Changes in accounting estimates are handled prospectively, with the change affecting the financial statements for the period of change and future periods. No adjustments are made to prior statements, and the adjustment is not shown on the face of the income statement.
