If the total comes to less than 90%, you will be required to opt-in to reportin on additional non-core sources to reach the 90% level. The first year assessment of the 90% rule will be made during the period from April 2010 to March 2011 (the frist year of the scheme). This reporting must be must be reported by 31st July 2011.
