UK - CSC UK is to close its £755m (US$1.2bn) defined benefit pension scheme to existing members.
The IT services company said the pension scheme liabilities had a substantial impact on its competitiveness and profitability in the market place.
It also said maintaining the CSC Computer Sciences Ltd Pension Scheme would materially impact the financial viability of its UK business.
CSC spokeswoman Joanne Davis said: "CSC can confirm it is to close its defined benefit pension scheme to existing members in common with many companies around the world."
CSC UK, which employs 7500 staff located across 100 sites in the UK and Ireland, will close the scheme from April 1, 2010. It already runs a defined contribution arrangement for staff.
CSC has followed rivals Fujitsu and IBM in closing its final salary scheme.
In May Fujitsu announced it would be closing its DB scheme to existing members, then in July IBM also said it was to close its DB scheme to future accrual.
A number of pension schemes have been prompted to lock in gains with a move into bonds after the estimated deficit across FTSE 100 DB pension schemes improved by £36bn, over the 12 months ending 30 June last year, JLT Employment Benefits found.
