A contributory period is, for the purposes of this subdivision, the number of contributory days comprised in the period during which the employee was a member of the plan in a year or comprised in the period during which days and parts of a day were otherwise credited to him or her with contributions, except the days and parts of a day determined by regulation, out of the number of contributory days in the year concerned, namely, 200 or 260, according to the basis of remuneration. The first contributory period of a new employee who is a member of the plan begins on the first day in respect of which the employee was assessed or exempt from contributions and the last period ends on the last day in respect of which the employee was assessed or exempt from contributions.
