Another lobbying group will be woring for small business interests in Washington. The American Business Conference, modeled after The Business Roundtable, is made up of chief executive officers of mid-sized growth companies (annual revenues between $20 million and $1 billion; minimum compounded annual growth rate of 15% per year over the past five years). The head of the ABC is Arthur Levitt, Jr., who was chairman of the White House Conference on Small Business last year.
