On April 2, 2020, the U.S. Small Business Administration (SBA) posted on its website an interim final rule relating to the implementation of Sections 1102 and 1106 of the Coronavirus Aid, Relief, and Economic Security Act (CARES Act or the Act) (published in the Federal Register on April 15, 2020). Section 1102 of the Act temporarily adds a new product, titled the “Paycheck Protection Program,” to the U.S. Small Business Administration’s (SBA’s) 7(a) Loan Program. Subsequently, SBA and the Department of the Treasury (Treasury) issued additional interim final rules implementing the Paycheck Protection Program (PPP). On June 5, 2020, the Paycheck Protection Program Flexibility Act of 2020 (Flexibility Act) was signed into law, amending the CARES Act. This interim final rule revises interim final rules posted on SBA’s and the Department of the Treasury’s websites on May 22, 2020 (published on June 1, 2020, in the Federal Register) and June 22, 2020 (published on June 26, 2020, in the Federal Register), by providing additional guidance concerning the forgiveness and loan review processes for PPP loans of $50,000 or less and, for PPP loans of all sizes, lender responsibilities with respect to the review of borrower documentation of eligible costs for forgiveness in excess of a borrower’s PPP loan amount.
