The amount to be borne by a member is a half of the total amount resulting from multiplying each of the member’s “Monthly Standard Salary” and “Standard Bonus” by the respective premium rate. If the amount contains any fraction, it is processed as follows:
When the school deducts the amount to be borne by the member from the member’s salary, if the halved amount has a fraction of 50 sen or less, the fraction is rounded down to 0 and if the fraction is 50 sen or more, it is rounded up to the nearest 1 yen.
