5 CFR § 2635.503 - Extraordinary payments from former employers.
(a) Disqualification requirement. Except as provided in paragraph (c) of this section, an employee shall be disqualified for two years from participating in any particular matter in which a former employer is a party or represents a party if he received an extraordinary payment from that person prior to entering Government service. The two-year period of disqualification begins to run on the date that the extraordinary payment is received.
(b) Definitions. For purposes of this section, the following definitions shall apply:
(1) Extraordinary payment means any item, including cash or an investment interest, with a value in excess of $10,000, which is paid:
(i) On the basis of a determination made after it became known to the former employer that the individual was being considered for or had accepted a Government position; and
(ii) Other than pursuant to the former employer's established compensation, partnership, or benefits program. A compensation, partnership, or benefits program will be deemed an established program if it is contained in bylaws, a contract or other written form, or if there is a history of similar payments made to others not entering into Federal service.
(c) Waiver of disqualification. The disqualification requirement of this section may be waived based on a finding that the amount of the payment was not so substantial as to cause a reasonable person to question the employee's ability to act impartially in a matter in which the former employer is or represents a party. The waiver shall be in writing and may be given only by the head of the agency or, where the recipient of the payment is the head of the agency, by the President or his designee. Waiver authority may be delegated by agency heads to any person who has been delegated authority to issue individual waivers under 18 U.S.C. 208(b) for the employee who is the recipient of the extraordinary payment.
