New shares of seasoned equity offerings are often issued with a sustainable discount. This discount implies a dilution in the sphere of old shareholders. Now, at least in Germany the old shareholders are commonly compensated for the dilution effect by issuing rights. However, the dilution also affects the owners of equity derivatives.
In a simple model we propose economic reasonable conditions for adjustments of European equity call option contracts after a seasoned equity offering issuing new shares. Therefore, we separate the effect of the equity increase and the effect of altering the leverage and operational risk. In particular, we discuss two suggested methods to adjust the contract terms of call options and analyse the dilution effects for the adjustments proposed by the 'Wiener Borse' and the EUREX.
