In my understanding, it makes sense to execute in-the-money american call options early ahead of the dividend when the extrinsic option value (related to time, volatility, etc.) is smaller than the dividend amount. I wonder, how often is a call option assigned early in the above situation in...

Thank you for your answer! I absolutely love IB (especially after TD Waterhouse)! Just one minor question: I understand you will disable shorting stock CFD if stock becomes unavailable for shorting. Is it correct?
