I exercised unapproved Share Options and all costs/valuations in my Merrill account are in USD when I need to self-declare in EUR. I haven't sold the shares so haven't received any money but need to enter the costs. Do I use the exchange rate of the day it was exercised and if so where do I source that as I understand it will be slightly different depending on where I look? If I Revenue have a different calculation can that be rectified later and could it cause issues?
Thanks in advance!
