30.—(1) The pensionable pay for the 2008–2009 scheme year in respect of a member's part-time employment is such amount as would, in the opinion of the Department, be the pensionable pay for a comparable whole-time employment under which services of the kinds performed in the part-time employment were performed on the assumption in paragraph (2).
(2) In forming that opinion, the Department must assume that the pensionable pay for the part-time employment is the part-time amount.
(3) In paragraph (2) “the part-time amount” means the amount that would be the pensionable pay for the part-time employment if it were determined in the same way as the pensionable pay for a whole-time employment is determined under regulation 29.
(4) If, apart from this paragraph, the pensionable pay for a scheme year in respect of a member's part-time employment would not be a whole number of pounds, it must be rounded down to the nearest whole pound.
