The NCUA Board (Board) is issuing this interim final rule to make a conforming amendment to its capital adequacy regulation following the enactment of the Coronavirus Aid, Relief, and Economic Security Act (CARES Act). The CARES Act authorizes the Small Business Administration to create a loan guarantee program, the Paycheck Protection Program (PPP), to help certain businesses affected by the COVID-19 pandemic. The CARES Act requires that PPP loans receive a zero percent risk weighting under the NCUA's risk-based capital requirements. To reflect the statutory requirement, the interim final rule amends the NCUA's capital adequacy regulation to provide that covered PPP loans receive a zero percent risk weight. The interim final rule also provides that if the covered loan is pledged as collateral for a non-recourse loan that is provided as part of the Board of Governors of the Federal Reserve System's (FRB) PPP Lending Facility, the covered loan can be excluded from a credit union's calculation of total assets for the purposes of calculating its net worth ratio. The interim final rule also makes a conforming amendment to the definition of commercial loan in the NCUA's member business loans and commercial lending rule. The Board has found good cause to issue the interim final rule without advance notice-and-comment procedures and with an effective date upon publication.
