The last set of annual accounts showed a pension deficit of about £10M. This is allowed for in the NAV.
The pension funds had £22M invested in equities, and had assumed a return on equities of 7% pa.
However, the return over the last year may have been substantially above that. The FTSE 100 is up about 17% (+ dividends) while the FTSE 250 is up nearer 25% over the year.
Perhaps there will be a reduction in the pension deficit and an exceptional profit of £2M or so this year.
