They say the terms and expiry should be clearly stated so shareholders have info to vote. Instead, both the terms and the expiry are hidden.

It doesn't say PS can't be retrospective, but everything implies that they are for future performance, which is obvious.

So that's two rules broken, with a possible third (implicit) rule broken.

I'd say the rules were broken in 2014 too when "licencing fees" were expanded by email to mean "any income" from a licenced product, IIRC.
