Value Dilution
Value dilution describes the reduction in the current price of a stock due to the increase in the number of shares. This generally occurs when shares are issued in exchange for the purchase of a business, and incremental income from the new business must be at least the Return on equity (ROE) of the old business. When the purchase price includes goodwill, this becomes a higher hurdle to clear.
The theoretical diluted price, i.e. the price after an increase in the number of shares, can be calculated as
Theoretical Diluted Price = ((O x OP) +(N x IP)) / (O + N) where
O = original number of shares
OP = Current share price
N = number of new shares to be issued
IP = issue price of new shares
For example if there is a 3-for-10 issue, the current price is $0.50, the issue price $0.32, we have
O = 10, OP = $0.50, N = 3, IP = $0.32 and TDP = ((10x0.50)+(3x0.32))/(10+3) = $0.4585
