Included in the regulation O definition of extension of credit (see
§215.3(a)(6)) is an advance of salary or other compensation of more than 30 days.
So, if you pay directors their fees quarterly, you should always make sure they are being paid in arrears, and not in advance. If you pay a director his first quarter fees on January 2, and he doesn't finish "earning" them until March 31, you've paid at least 2/3 of the fee more than 30 days in advance. That makes it a "free" loan, which is clearly
verboten under Reg. O.
