This final rule amends the regulations pertaining to the determination of size eligibility based on affiliation by creating distinctive requirements for small business applicants for assistance from the Business Loan, Disaster Loan and Surety Bond Guarantee Program ("SBG"). For purposes of this rule, the Business Loan Programs consist of the 7(a) Loan Program, the Microloan Program, the Intermediary Lending Pilot Program ("ILP"), and the Development Company Loan Program ("504 Loan Program"). Note: the Intermediary Lending Pilot Program was inadvertently left out of the proposed rule. There are currently intermediaries with revolving funds for eligible small businesses, so the program has been included in this final rule. The Disaster Loan Programs consist of Physical Disaster Business Loans, Economic Injury Disaster Loans, Military Reservist Economic Injury Disaster Loans, and Immediate Disaster Assistance Program loans. This rule redefines and establishes separate affiliation guidance applicable only to small business applicants in these Programs.
