Thanks for the link, Alex001. I didn't know that this fund was still in existence. I had assumed that it was discontinued after the divorce. It is very nice that they are able to work together.
As far as I know, they've been handing out money every year since the divorce - I wasn't sure what would happen to it now that Joachim is married to Marie, but it seems that they have no intention of ending the fund - and good for them! I think it's great that they can still co-operate to the extent of carrying out official functions together.
