SBA loan basics
How does the SBA define 'affiliation' when checking business size?
Short answer
SBA defines 'affiliation' by various factors, like ownership, management, and contractual relationships, to determine if businesses are linked and should be combined for size standard calculations.
The rule
The SBA's affiliation rules aggregate the employees and revenues of all businesses deemed 'affiliated' to ensure that only truly small businesses receive assistance. Common bases for affiliation include ownership (e.g., a single entity owning 50% or more of another), common management, common identity of interest, and contractual relationships. If affiliated businesses together exceed the size standard, the applicant business is ineligible.
Facts that matter
- Aggregates businesses
- Ownership control
- Common management
- Size standard impact
Example structure
John owns 60% of Business A and 30% of Business B. Sarah owns 70% of Business B. John's ownership in Business B is less than 50%, but he has significant control. If the SBA determines John's businesses are affiliated due to common management or other factors, the employees and revenue of Business A and B would be combined to determine if either qualifies as 'small'.
