Demerger of mmO₂ – capital gains tax calculation
The confirmed official opening prices for BT Group and mmO₂ shares on 19 November 2001 following the demerger were 285.75p and 82.75p, respectively. This means that, of the total (combined) value of 368.50p, 77.544% is attributable to BT Group and 22.456% to mmO₂. Accordingly, for CGT calculations, the base cost of your BT Group shares and mmO₂ shares is calculated by multiplying the acquisition cost of your BT shareholding by 77.544% and 22.456%, respectively.
