This final rule implements legislative changes to size eligibility requirements for assistance from Small Business Investment Companies (SBICs) and Certified Development Companies (CDCs), and for the Agriculture industry. The Small Business Investment Improvement Act of 1999, codified in sections 103(5) and 103(12) of the Small Business Investment Act of 1958, as amended, established a method for determining the eligibility of a business that is not required to pay Federal income tax at the corporate level, but that is required to pass income through to its shareholders or partners. The new method treats "pass-through" enterprises the same as firms that pay Federal taxes for the purpose of size standard determinations. The Small Business Reauthorization Act of 2000, codified in section 3(a)(1) of the Small Business Act, increases the size standards used for Agriculture from $500,000 to $750,000 in average annual receipts.
