15 U.S.C. § 19: Interlocking directorates and officers

engaged in whole or in part in commerce; and by virtue of their business and location of operation, competitors, so that the elimination of competition by agreement between them would constitute a violation of any of the antitrust laws; the competitive sales of either corporation are less than $1,000,000, as adjusted pursuant to paragraph (5) of this subsection; the competitive sales of either corporation are less than 2 per centum of that corporation’s total sales; or the competitive sales of each corporation are less than 4 per centum of that corporation’s total sales. The eligibility of a director or officer under the provisions of paragraph (1) shall be determined by the capital, surplus and undivided profits, exclusive of dividends declared but not paid to stockholders, of each corporation at the end of that corporation’s last completed fiscal year. For purposes of this section, the term “officer” means an officer elected or chosen by the Board of Directors. For each fiscal year commencing after September 30, 1990 , the $10,000,000 and $1,000,000 thresholds in this subsection shall be increased (or decreased) as of October 1 each year by an amount equal to the percentage increase (or decrease) in the gross national product, as determined by the Department of Commerce or its successor, for the year then ended over the level so established for the year ending September 30, 1989 . As soon as practicable, but not later than January 31 of each year, the Federal Trade Commission shall publish the adjusted amounts required by this paragraph. When any person elected or chosen as a director or officer of any corporation subject to the provisions hereof is eligible at the time of his election or selection to act for such corporation in such capacity, his eligibility to act in such capacity shall not be affected by any of the provisions hereof by reason of any change in the capital, surplus and undivided profits, or affairs of such corporation from whatever cause, until the expiration of one year from the date on which the event causing ineligibility occurred.
