(I) the aggregate of the gross compensation which may be paid to employees in the office of such Senator for the fiscal year ending September 30, 1988, as determined under this subsection (but without regard to this subparagraph), exceeds
(II) the aggregate amount of gross compensation which is paid to employees in the office of such Senator for that part of such fiscal year which precedes January 1, 1988, plus
