Re: the above document.

To me it looks like Citibank tried issued a principal protected security of 4 years duration with up to eur 30m available in “climate change opportunities” and sold 3.528m. Is this an accurate assessment of this document?

Does it not filling its full subscription show either a lack of faith in green technology companies over the next four years or a huge lack of faith in Citibank?

Or am I reading it totally wrongly??

Read the same notice. Could not understand it. Might be something to do with not selling a fund.

But the question to me is why did this fund not sell? (If that is what the notice is telling us).
