How should the net cumulative effect of a change in accounting principles be reported?

The net cumulative effect of a change in accounting principles should be reported as a restatement of beginning net assets. This approach reflects the inherent intention behind accounting changes, which is to present financial statements that are more accurate and reflective of the entity’s financial position and performance.

When an organization adopts a new accounting principle, it's essential to adjust the previously reported financial statements to show what they would have looked like had the new principle been in place all along. This restatement impacts the beginning net assets for the period in which the change is implemented. By doing so, stakeholders can see the effect of the change clearly and understand how it has affected the organization’s equity and financial condition from the outset of the reporting period.

In contrast, options like reporting it as a program expense/general revenue or a special item would not accurately represent the cumulative effect of the accounting change. These methods do not provide the clarity required around adjustments that fundamentally alter prior financial statements. Moreover, a separate "cumulative effect" adjustment may not meet the reporting standards that require the impact to be reflected directly in the net assets rather than treated as a separate line item.
