Part 2640 of this chapter interprets and is the implementing regulation for 18 U.S.C. 208. This subpart summarizes the relevant statutory restrictions and some of the regulatory guidance found there. Specifically, this subpart contains two provisions relating to financial interests. One is a recusal requirement and the other is a prohibition on acquiring or continuing to hold specific financial interests. An employee may acquire or hold any financial interest not prohibited by § 2635.403. Notwithstanding that the acquisition or holding of a particular interest is proper, an employee is prohibited in accordance with § 2635.402 from participating in an official capacity in any particular matter in which, to the employee's knowledge, the employee or any person whose interests are imputed to the employee has a financial interest, if the particular matter will have a direct and predictable effect on that interest.
