Actually, that is the current formula, as the legislation has not been amended. According to the current formula, overtime will not be taken into account. As I said, the legislation is drafted in a strange way. In some cases, it says that the wages of a person paid on a weekly basis will not be reduced, but by definition, that excludes overtime. There are also regulatory provisions on the calculation that apply to people with flexible schedules. Once again, the process is fairly complex. However, the legislation specifically indicates that overtime does not count. It is excluded by definition.
