Conversion premium
Calculate conversion value from the number of shares obtainable and their current price. The currency premium is convertible price minus conversion value; a percentage premium commonly divides that excess by conversion value, but state the convention. The premium can reflect debt payments, downside characteristics and option time value, not a guaranteed profit. A bond may be unattractive to convert immediately yet still have value because conversion can occur later. Distinguish current conversion value from the forecast value at maturity used in a simplified valuation.
Worked example
A bond priced at $120 converts into 20 shares currently worth $5 each. Current conversion value is $100, so the currency premium is $20 and the premium relative to conversion value is 20%.
Common mistake
Confusing the premium with an immediate arbitrage gain, or mixing current conversion value with a forecast future share price.
