Rate of basic pay
Rate of basic pay means the rate of pay fixed by law or administrative action for the position held by an employee, including any special rate under 5 CFR part 530, subpart C; locality-based comparability payment under 5 CFR part 531, subpart F; or similar payment under other legal authority, but before deductions and exclusive of additional pay of any other kind. For example, a rate of basic pay may not include nonforeign area cost-of-living allowances under 5 U.S.C. 5941, night shift differentials under 5 U.S.C. 5343, or environmental differentials under 5 U.S.C. 5343(c)(4).
