For the Glazers it has.
For the club it has been a huge drain on resources. They have taken 550mil out to pay for their debts they put on the club. I know that no matter who owns the club there has to be a payout(unless you have a sugar Daddy) but it does seem very high.
In the end it seems to be all working out but it doesn't takeaway from the fact that with proper regulation we would never have been in this mess in the first place.
I'm assuming that you're not referring to our on-field performance as a "mess" (5 Prems and two 2nds in the last 7 years together with 3 CL finals, a WCC and sundry cups and shields), so you must be talking about the financial side. Hopefully you understand that mssrs Harris, O'Neill, Green and Drasdo were hell bent on making things look as bad as possible. The "550 mill" figure is an artifact of this. It's easiest to get at the reality by looking at cash flows in and out of the club over the 7 years from 2005 to 2012.
Total revenue: 1,856.144 mill
Player sales: 177.847 mill
Total Cash Inflow: 2,033.991 mill
Staff costs: 878.898 mill
Operating expenses: 384.397 mill
Net fixed assets: 89.561 mill
Player purchases: 294.867 mill
Total Cash Outflow: 1,647.723 mill
Difference: 386.628 mill
The "Difference" figure is essentially the operating surplus generated by the club. If we were still a plc both taxes and dividend would be paid out of that surplus. I estimate that the total of taxes and dividends over the period would have been around 240 mill; Green estimates the figure to be closer to 190 mill. In a spirit of compromise I'll split the difference and assume 215 mill. That leaves 171 miil that we have to account for. 5 mill went to increasing our cash reserve, so we are left with 166 mill that the Glazers are responsible for - not a small amount, but not 550 mill.
There are a couple of further twists to this story. There's an assumption hidden in there that, if we had continued as a plc, we would have generated the same revenues and, in particular, that the same growth in Commercial revenues would have occurred - even Green (andersred) has given up claiming that as likely. If the plc would have generated less revenue, the "cost of the Glazers" goes down from the 166 mill. But that might not be the most important impact.
The plc was wedded to the rule that player costs should be less than 50% of revenue. Without the immediate increase in commercial revenues - the shift to AIG and the increase in other sponsorships - that occurred after the LBO, salary growth would not have been possible within the constraint. In particular, it seems likely that we would only have been able to sign two of Evra, Vidic and Carrick - oops. Of course we'll never know what would have happened, but it's not inconceivable that a significant element of our on-field success was dependent on the growth of commercial revenues, and who knows what SAF would have done if he felt the board was not supporting him. Anyway, it's a good story and, before we get too busy condemning the Glazers, I suspect that a glance at the bigger picture might not be a bad thing. Blood sucking leeches vs. the saviours of our team????????????
