Tabular disclosure of the change in an accounting estimate, including a change that occurs in an interim period. If a change in accounting estimate affects several future periods (for example, a change in the service life of a depreciable asset) disclose the effect on income from continuing operations, net income (or other appropriate captions of changes in the applicable net assets or performance indicator), and any related per-share amounts of the current period. Disclosure of the effects of a change in an accounting estimate that occurs in the ordinary course of business (such as uncollectible accounts or inventory obsolescence) is not required, unless the effect is material.
