倒数第二段原文：
The company carries out a valuation of the group pension scheme every three years. So it was due in 2006. If you look at the next chart, you'll see that scheme is 72% funded compared with 95% at the time of the previous valuation three years ago. This is because we've been getting low returns on some of their investment.  We have therefore increased financial contribution to the scheme. And under current plans, the deficit will be eliminated over a 12 year period.
