The option of the FRSSE SORP is available for reporting periods beginning on or
after 1 January 2015 but is not available for later reporting periods beginning
on or after 1 January 2016. If your reporting period begins on or after 1
January 2016 you must use the FRS 102 SORP because the FRSSE has been withdrawn
for these later reporting periods.
Does your reporting period begin after 1 January 2015 and before 1 January 2016?
