Capital Gains Tax on National Grid Rights issue

TheTinker

I sold my nil-paid rights in NG last year. Can anyone tell me how I establish the base cost for the rights?
Thanks for any help!

Were the sale proceeds less than 5% of the value of the shares you hold? 

TheTinker

Hoenir: No. Value of sale was about 6.5% of the value of the National Grid shares

If not, “small” - 5% or less:

To calculate the chargeable gain on a part-disposal, deduct from the sale proceeds the part of the original cost of the asset by using the fraction: A /(A+B), Where A is the gross disposal proceeds and B is the value of the part retained.
