The NCUA Board (Board) is amending its regulation governing assessment of an annual operating fee to Federal credit unions (FCUs). First, for purposes of calculating the annual operating fee, the final rule amends the current rule to exclude from total assets any loan an FCU reports under the Small Business Administration's Paycheck Protection Program (PPP) or similar future programs approved for exclusion by the NCUA Board. Second, the final rule deletes from the current regulation references to the Credit Union System Investment Program and the Credit Union Homeowners Affordability Relief Program, both of which no longer exist. Third, the final rule amends the period used for the calculation of an FCU's total assets. Currently, total assets are calculated using the FCU's December 31st Call Report of the preceding year. Under the final rule, total assets will be calculated as the average total assets reported on the FCU's previous four Call Reports available at the time the NCUA Board approves the agency's budget for the upcoming year, adjusted for any excludable programs as determined by the Board. Finally, the final rule makes some minor technical changes.
