If a request for standardized remuneration to be revised or decided has been filed, the implementing organization may revise or decide the parties' standardized monthly amounts of remuneration to be the amounts specified in each of the following items for each month of an insured period falling under the subject period in which the person subject to a class I revision has a standardized monthly amount of remuneration:
person subject to a class I revision:the amount arrived at when the revision percentage (meaning the rate calculated as specified by Order of the Ministry of Health, Labour and Welfare, based on the allocation percentage; the same applies hereafter) is deducted from the number 1 and the resulting rate is multiplied by the standardized monthly amount of remuneration (or by the previous standardized monthly amount of remuneration specified in Article 26, paragraph (1), for a month in which the previous standardized monthly amount of remuneration is deemed to be the standardized monthly amount of remuneration pursuant to that paragraph; the same applies in the following item) prior to the revision;
person subject to a class II revision:the amount arrived at when the person's standardized monthly amount of remuneration prior to the revision (or 0 for a month without a standardized monthly amount of remuneration) is added to the amount arrived at when the revision percentage is multiplied by the person subject to a class I revision's standardized monthly amount of remuneration prior to the revision.
If a request for standardized remuneration to be revised or decided has been filed, the implementing organization may revise or decide the parties' standardized amounts of bonuses to be the amounts specified in each of the following items for each month of an insured period falling under the subject period in which the person subject to a class I revision has a standardized amount of bonus:
person subject to a class I revision:the amount arrived at when the revision percentage is deducted from 1 and the resulting rate is multiplied by the standardized amount of the bonus prior to the revision;
person subject to a class II revision:the amount arrived at when the person's standardized amount of bonus prior to the revision (or 0 for a month without a standardized bonus) is added to the amount arrived at when the revision percentage is multiplied by the person subject to a class I revision's standardized amount of bonus prior to the revision.
In a case as referred to in the preceding two paragraphs, a period falling under the subject period that is an insured period for the person subject to a class I revision but not an insured period for the person subject to a class II revision is deemed to be an insured period for the person subject to a class II revision.
The standardized remuneration revised or decided pursuant to the provisions of paragraph (1) and paragraph (2) is effective only prospectively, starting from the day of the relevant request for standardized remuneration to be revised or decided.
