It's a bit complicated. Jassim's bid is for the whole club, and he will absorb the debt. Ratcliffe wants to purchase the Galzer's portion of the share alone, so debt will remain on the books unless he decides to infuse more equity in which will be difficult because of listing requirements in the stock exchange on public float.
That would be my understanding and Sir Jim would be tied into the into the ownership mess.
So if the Glazers wanted to merely fix the roof at Old Trafford they would have the following options
1 that they would independently invest/pay 80% towards the cost, being 80% owners of the club, then get the Class A shareholders to pay the other 20%. Chances of this happening are zero. There's no way the Glazers are going to be putting 80% of their own money never having invested in that way before. Also there is no way the other shareholders are going to be putting 20% because they receive little return and have no control.
2 Glazers independently meet the whole cost. There's no way the Glazers will meet the cost for the reasons given above and also they will be subsidising the Class A shareholders by, in effect, giving them 20%
3 the Glazers/club obtain external finance, say a bank, however they seem to have maxed out the credit facilities unless they offer the bank some greater incentive however these businessmen know that all of the finances are finely balanced and therefore by borrowing more things will deteriorate, financially, even more than they are now.
4. Plough some profits into the repairs, but they haven't had dividends for a couple of years and the siblings are already restless.
4. Their thinking would be - there is no profit in repairing the roof but they may have to due the safety and regulatory reasons otherwise why waste money!
