With the excepetion of the number of producers and their names (look in your playbill or on IBDB), most of the rest of that information is private, confidential information which producers are under no obligation to report to the general public (and thus, they don't). While the occasional capitalization figure or weekly nut amount manages to slip out via insiders, that info generally isn't published or freely available.
