Generally, the examiners look at volume ($ and #) to determine which product gets the most weight. In fact, if volume is very very low, a product might be omitted from consideration. However, they are anticipating increased volume of small biz lending due to the PPP loans, but also some problems with the data, particularly due to PPP loans not requiring revenue data. Lack of revenue data will impact the analysis - and not in a good way. So, the agencies put out some Q&As May 27, 2020/updated March 8, 2021.
Of particular relevance is the following from question 7: When evaluating CRA performance, the agencies will take into account the unique circumstances affecting borrowers and banks resulting from the COVID-19 emergency and will not penalize a bank for making a large volume of loans for which gross annual revenue information is not available. The agencies will also take into account a bank’s good faith efforts demonstrably designed to support low- and moderate-income individuals and small businesses and small farms and its efforts to comply with applicable consumer protection laws.
