This is 2007, buddy... No one prints 100 page statements anymore... You just save it to disk as an HTML or WORD file. And, yes, IB make all kinds of "retroactive" adjustments... Like they OFTEN pay dividends late... And then pretend it was done on time by printing a "retroactive" payment date... While interest is lost by the Customer. IB will do anything to drive profit margins from 54% to 55%. A few cents here... and a few cents there... A few more employees axed... It all adds up to millions.
If that's the case, why don't we charge for exercise and assignments? Why do we offer extremely competitive financing rates? Why do we pay interest on stock loan? Why don't we charge for the first outgoing why each month etc etc? Those are just a few examples of costs which we could easily pass on or adjust to increase our profit margin if as you say we would "do anything to drive profit margins [higher]". It sure would be nice if someone actually thought a bit before making a negative statement without any factual knowledge.
Actually you charge for the exercise of the Kospi Futures which is weird because they are cash settled
I should have clarified that I was specifically talking about US stock index options where we eat the cost. We do pass on the KOSPI fees we are charged.
