BA's has not doubled 52049er: FT.com "BA’s pre-tax pension liability under accounting rules, for all schemes in deficit,
increased from £2.19bn to £2.29bn in the year to the end of March and the accounting deficit in the main fund, the New Airways Pension Scheme,
rose by £101m to £2.1bn."
Cleverer people than (you? &) I are looking into this as we speak. Do you understand that we are dealing with projections?
Matey, I understand perfectly. Do you?
Also: "Following changes in pension legislation, scheme trustees are responsible for setting the assumptions used in the actuarial valuation process, and Mr Maynard warned Naps members, that the trustees would need to be more cautious than they had been three years ago at the time of the last valuation."
Roger Maynard appears to be your man to ask about what "assumption" changes have occurred.
