Conversion premium
From ACT Wiki
The premium over an ordinary share's current market price at which the holder of the convertible security may convert it into ordinary shares.
Example
The current market price of ordinary shares is £2.
The conversion price is £2.50.
The conversion premium is given by:
= (2.50 - 2.00) / 2.00
= 0.50 / 2.00
= 25%.
