They would still have to plug the pension deficit, millions, even if the the Final Salary was converted to say Money Purchase but they could then move on with a clean sheet. They can't keep physically keep throwing money at the problem for ever. I had the same done on me recently, one third of my companies expenses was going on supporting the old plan which was converted to a cheap, company contributes 5%, money purchase scheme. The deficit in this case was 12 million and the cost to wind it up was 5 million which was paid within months. The last resort but I expect to see more of it over the coming year.
