The U.S. Small Business Administration (SBA) is issuing this direct final rule to permanently adopt the temporary size standard implemented under the American Recovery and Reinvestment Act that is now in effect through September 30, 2010 for the Surety Bond Guarantee Program. The direct final rule provides that a business concern is small if such concern, combined with its affiliates, does not exceed the size standard for the North American Industry Classification System (NAICS) code that corresponds to the primary industry of the business concern combined with its affiliates.
