The answer, I think17 Mar 2008 10:33
You will get 1 Impellam share for 50.4 CSV shares. The price of the Impellam share depends on the price of Carlisle, since Carlisle shares are being exchanged for Impellam shares on a 1-for-1 basis.
The calculation of 2.15 is based on the price of Carlisle shares being 108p, but this calculation is merely illustrative.
The market makers this morning seem to have misunderstood the situation and have marked the price of Carlisle shares down to 100-108p. However, the price will have to drop a further amount to account for £4m of the assets being given out as the Shellproof dividend, which at the present valuation of Carlisle at 108p would take the price of Carlisle down to around 90p (a drop of 13.5%). As of writing this would value CSV shares at 90p / 50.4 = 1.78.
However, Carlisle is now grossly undervalued at a PE of around 5, so the long term prospects look good whether you buy CSV or you buy CXG.
