A request under the provisions of the preceding paragraph must be made for all persons who are to become covered employees under a retirement allowance mutual aid contract at the same time as the application for the retirement allowance mutual aid contract is made (excluding a covered employee under a retirement allowance mutual aid contract that is the subject of a request under Article 31-2, paragraph (1) or Article 31-3, paragraph (1)).
前項の規定による申出は、退職金共済契約の申込みが行われることにより同時に退職金共済契約の被共済者となるべき全ての者（第三十一条の二第一項又は第三十一条の三第一項の規定による申出に係る退職金共済契約の被共済者を除く。）についてしなければならない。

The past service monthly amount must be specified, in consideration of the trend of monthly premiums and other factors, from among the amounts specified by Order of the Ministry of Health, Labour and Welfare in accordance with the categories prescribed in Article 4, paragraph (3) (which are to be amounts of 5,000 yen (or, for a short-time covered employee, 2,000 yen) or more), within a range not exceeding the monthly premium on the day on which the retirement allowance mutual aid contract for that covered employee takes effect.
