Well done @phlebas192 and @wmb194.  

Indeed, what stars all contributors have been, I’m indebted to all.

Your purchase from 1996 should certainly be increased in line with indexation which will be to your benefit.

No, indexation doesn't apply at all to disposals made after a certain date (which is now many years ago).

Thanks for the correction.

Applying the formulae kindly provided i.e.  (Total cost that I managed to establish * 15.8827107% / by the number of shares held) the outcome suggests, in my situation at least, the cost per share is 97p.

I feel more content running with that.

Edit 15/01/2026. While this value is probably on the on the low side, in the absence, of evidences of further purchases, I shall run with this. 

Thanks for all the input.

Overjoyed …an understatement . Finding this ‘thread’ just as i am about to 'offload' some of my BAE SYSTEMS shares…acquired through the Marconi - British Aerospace merger at the end of 1999. Gifted 50% to my wife, thus enjoying the dividend payments together over the last ten years. With the tax allowance on the dividends now soon to disappear ? Dont need a crystal ball to predict that.

Time has come to sell in small chunks. non CGT liability @ <£3000 . ? Pretty sure thats right.

FYI: I recall joining ‘GEC’ in 1974 and was soon enrolled in the company share save scheme. Max spend of £250 per ‘preference release. Within a few years gaining a healthy portfolio of 4600 shares.

I was fortunate to remain with the business through its many changes , GEC - Marconi -BAe -BAE SYSTEMS. Somehow, i cannot workout, managing to leave in 2010 with an intact portfolio despite the huge loses incurred during the disastrous fiscal prestidigitations of Simpson and Mayo. 12.50p to 0.04p in matter of days.

You had to be there to truly understand the atmosphere .

This thread is going to make interesting reading. Many thanks to all.

Your employment history experience mirrors mine.

Well, the recent surge in BAE's share price has helped compensate for the disastrous failure in the value of Marconi stocks.

The CGT liability is the real sucker punch when it comes to the disposal of the inherited BAE stock.

I'm holding on for now in the hope/belief that the current upward trend in price will continue and help compensate for the CGT hit.
