5 C.F.R. § 2635.601
This subpart contains a recusal requirement that applies to employees when seeking non-Federal employment with persons whose financial interests would be directly and predictably affected by particular matters in which the employees participate personally and substantially. Specifically, it addresses the requirement of 18 U.S.C. 208(a) that an employee not participate personally and substantially in any particular matter that, to the employee's knowledge, will have a direct and predictable effect on the financial interests of a person with whom the employee is negotiating or has any arrangement concerning prospective employment. See § 2635.402 and § 2640.103 of this chapter. Beyond the statutory requirement in 18 U.S.C. 208(a) , this subpart also addresses issues of lack of impartiality that require recusal from particular matters affecting the financial interests of a prospective employer when an employee's actions in seeking employment fall short of actual employment negotiations. In addition, this subpart contains the statutory notification requirements that apply to public filers when they negotiate for or have agreements of future employment or compensation. Specifically, it addresses the requirements of section 17 of the Representative Louise McIntosh Slaughter Stop Trading on Congressional Knowledge Act (STOCK Act), Public Law 112-105, 126 Stat. 303, that a public filer must submit a written statement identifying the entity involved in the negotiations or agreement within three business days after commencement of such negotiations or agreement and must submit a notification of recusal whenever there is a conflict of interest or an appearance of a conflict of interest.
