C2.602 Computation of gains and losses
For disposals after 5 April 1988, assets which were acquired by their owner on or before 31 March 1982 are deemed to have been disposed of by him on that date and immediately reacquired at their then market value1. Thus, the expenditure allowable to the owner under TCGA 1992, s 38(1)(a) (see C2.202–C2.205) is the market value of the asset at 31 March 1982. 'Market value' is not specially defined for this purpose and therefore takes its normal meaning for capital gains tax purposes2.

However, if the indexation allowance computed by reference to actual expenditure would be greater, the greater amount applies, except where an election has been made to disapply the restrictions on
