I haven’t done my revision on GIPS yet but i would use elimination to GUESS the answer. I also skipped that optional part. There is something about fair value on or after 1 January 2011(The part for provisions of the GIPS standards(an overview) is NOT optional).So i would eliminate the second one which says 1 January 2015. The first choice doesn’t sound right-input data from third parties? Which leaves me with the third choice.
They say its optional then they test it? Its not fair.
