"Depends- global annual turnover or Europe?"
Global means "global" - aka whole planet. Which means what appears in their balance sheets they publish for Wall Street, in MS case - where they can't say "our revenues are zero and our profit negative" - because of course shares and executive bonuses will crumble instantly... nor turnover is easily affected by the tricks they can use to pay less taxes - investors want to see increasing revenues, profits, dividends, and share prices - and executives payouts depends on them too.
I believe that's why those who wrote the GDPR chose that value, companies can employ a lot of tricks to hide money, but they have to surface them somewhere eventually....
