What do you read into that mate?
I'm speculating of course mate:
I believe one of the named investors is a former president of GS - so he was either involved in the financial negotiations of investing in the ground or the investment opportunity was put to him through that route and he's put together a consortium of investors, to look at a possible takeover. Where Kenyon fits into this is anyone's guess - portably as a industry expert representing.
Id be guessing the reasoning is, if they fund the ground anyway - why not own it as opposed to just getting the interest in the investment and bet that it will be worth more 500mill + interest, if they sit on it for a couple of years, buying the club lock stock is an additional expense amongst them, but again an asset they would look to appreciate - though its a basket case, but sweating the stadium could help. Ive also wondered would they look to do something different with the Goodison legacy - its a big piece of land and site they could look to turn into something more profitable then what is planned. I think they are looking at fixed assets - Goodison, New ground and Club itself and seeing dollar signs if they can appreciate with minimal investment. For once we're fixed asset heavy.
A fear would be them separating church and state i.e. separating ownership of the ground from the club - though I've no reason to suspect that.
