(a)the first date of entitlement has been determined;
(b)it is subsequently determined that the first date of entitlement falls on a different date (the “start date”); and

(b)the amount payable in respect of that first assessment period is to be calculated as follows—

N is the number of days in the period; and
A is the amount calculated in relation to that period as if it were an assessment period of one month; and
(c)regulation 22(1) and (3) apply to the second and subsequent assessment periods as if the day after the end of the first assessment period were the first date of entitlement.]
