Final answer:
Under U.S. GAAP, the accounting changes that are considered are change in accounting principle, change in reporting period, and change in reporting entity.
Step-by-step explanation:
The three accounting changes that are considered under U.S. GAAP (Generally Accepted Accounting Principles) are:
- Change in accounting principle: This occurs when a company switches from one acceptable accounting method to another. For example, a company may change from the LIFO (Last-In, First-Out) method to the FIFO (First-In, First-Out) method for inventory valuation.
- Change in reporting period: This refers to a change in the timeframe for which financial statements are prepared. For instance, a company may switch from a calendar year-end reporting period to a fiscal year-end reporting period.
- Change in reporting entity: This occurs when there is a change in the business entity that is issuing the financial statements. For example, if a company is acquired by another company and becomes a subsidiary, there would be a change in reporting entity.
It's important to note that a change in accounting estimate is not considered an accounting change under U.S. GAAP. A change in accounting estimate refers to a revision in an estimate used in the preparation of financial statements, such as the useful life of an asset or the allowance for doubtful accounts.
