The amount of day laborer contributions collected from a day labor health society pursuant to the provisions of paragraph (1) of the preceding Article is the estimated amount of day laborer contributions for the relevant fiscal year; provided, however, that when the amount of estimated day laborer contributions for the preceding fiscal year exceeds the fixed amount of day laborer contributions in that fiscal year, the amount is the amount obtained by deducting the amount of excess from the amount of estimated day laborer contributions for that year, and when the amount of estimated day laborer contributions for the preceding fiscal year is less than the fixed amount of day laborer contributions in that fiscal year, the amount is the amount obtained by adding that amount of deficit to the amount of estimated day laborer contributions for that year.
