This is an exception row. It applies only in the situation described in the footnote printed with it. Read the footnote and the official text before using this figure.
Affiliation is not computed. Under 13 CFR 121.103 the receipts and employees of affiliates are generally counted, and affiliation turns on control and judgment. Only the SBA or the contracting officer can determine size.
How to use this figure
- Annual receipts are averaged over the most recent five completed fiscal years under 13 CFR 121.104(c)(1). Read the averaging guide.
- Affiliates' receipts are counted under 13 CFR 121.103. The calculator does not include them. Read the affiliation guide.
- The standard is one input. The solicitation's NAICS code and the SBA's own rules decide size.
