When applying retrospective adjustments, current GAAP requires the change to be applied so that it includes

A) only the years disclosed in the currently published financial statements
B) all possible years
C) only the earliest possible date from which it can be applied prospectively
D) retroactive application for up to two years and prospective application for the remainder of the periods

When applying retrospective adjustments, current GAAP requires the change to be applied only to the earliest possible date from which it can be applied prospectively, which is known as the "beginning of the earliest period presented." This means that the adjustment is not applied to all possible years (B) or only the years disclosed in the currently published financial statements (A). Additionally, retroactive application for up to two years and prospective application for the remainder of the periods (D) is not always allowed and depends on specific GAAP requirements.
