CGT base cost of Hays shares
Following the demerger, the original base cost of your Hays plc shares for Capital Gains Tax purposes should be allocated between your Hays plc shares and the DX Services plc shares that you received as follows:
Hays plc shares 89.57%
DX Services plc shares 10.43%
For example, suppose you held 100 Hays plc shares for which the base cost is £100. Immediately after the demerger, you held 100 Hays plc shares and 5 DX Services plc shares. The £100 cost should be allocated between these shares as follows:
Hays plc shares 89.57% x £100 = £89.57p, or £0.90p per share
DX Services plc shares 10.43% x £100 = £10.43, or £2.09p per share
If you are in any doubt about the allocation of the base cost between the shares of the two companies, you should consult your tax advisor.
