Figures to watch out for is the non performing loans and the costs.
Assuming a large part of the non performing loans are written off, KCB will only get about 90billion in extra assets vs customer deposits of 98 biliion.
Income side they are getting nothing.
How fast will they cut costs on the N.B.K side and at what cost is the question.
Share dilution isn't much, about 1% if you consider ordinary shares. How will prefence shares be handled?
