The fees due in April are those due for the same calendar year, but are normally calculated on the basis of the Islamic bank’s financials for the previous calendar year: i.e. the fee payable in April 2007 (for example), is that due for the calendar year 2007, and is calculated using the audited financial statements for 2006. Where a licensee does not operate its accounts on a calendar-year basis, then the most recent audited financial statements available are used instead.
