This interim final rule implements certain provisions of the American Recovery and Reinvestment Act of 2009 affecting small business investment companies (SBICs). These provisions increase the maximum amount of SBA leverage available to an SBIC, change the calculation of the maximum investment size that an SBIC is permitted to make, and simplify the requirement for an SBIC to devote a portion of its investment activity to smaller enterprises. SBA is publishing this rule as an interim final rule in light of the urgent need to help small businesses sustain and survive during this economic downturn.
