How often do these acquisition loans fail?
Fewer than 20 Medical Laboratories acquisition loans are old enough to measure losses reliably, so no charge-off rate is shown. The benchmark across all SBA acquisition loans in the FY2018 to FY2021 cohort is 3.5% by count. Non-acquisition 7(a) loans (every other stated purpose) approved FY2018 to FY2021 charged off at 6.2%.
"Charged off" is the SBA's final loss action on a defaulted loan after collection efforts. It lags default by a year or more, which is why only older cohorts are measured. It is not the same as a delinquency rate, and loans still outstanding can still fail. See charge-off in the glossary.
