My take on the 200m.
He didn't actually lend the club money as such, he just took on a pre existing debt from a prior lender. Doing so removed a huge potential banana skin for him as so long as that loan existed the very real chance existed they could refuse to extend the repayment date and take control of the club.
Now that threat no longer exists (for him)
By doing so, he has now great leverage on any future deal to buy the club, either as him doing so, or if another party comes in then they have to talk to Friedkin - no one can takeover Everton without paying off the 200m loan Friedkin now holds.
If in 8 months time nobody has bought the club by then Moshiris shares, and the rights to the stadium both pass to Friedkin.
He really does hold a great hand (in a poker way).
