Shall we open a sweepstake on how long Talk Talk survives?
My understanding of this process is that the firm is taken private by borrowing a vast sum of money, which is loaded in to debt for the holding company.
Next all but the central part that is making the most money is sold off or closed to give an apparently really profitable business.
This is then floated again, but the company is saddled with the massive debt from the going-private process, so as soon as the profitability drops off the debt repayment becomes too much and the company goes bust.
