Joey,
That's not 100% accurate.
Firstly, capitalization is not tabulated per se. The capitalization is specified in the offering papers for the show. It may be a what's known as a "mini/maxi" that gives some flexibility as to how much may be raised, but it is a finite amount from the start.
What I believe you are referring to is the final production costs which can be anything up to the maximum capitalization. If it's less, the extra money is generally set aside for a reserve. If it's more, the excess will typically need to be made up by priority loans.
As for how to figure out where Spiderman stands, it's pretty impossible to state accurately without specific access to the show's accounting.
Producers do budget for *additional* expenses during previews as part of the capitalization -- rehearsals, workcalls, possible script and/or physical production changes and associated expenses -- but the basic operation of the show in previews is treated as an operating expense.
So in the Spiderman's production budget is an allowance for expenses during previews. If they've been spending an extra $500K per week for tech and adjustments (which seems like a slightly high figure to me) than it's possible they have that money in the budget. Or it's possible they've already spent whatever the maximum their capitalization is legally allowed to be, in which case they would need to cover the "extra" $500K per week with priority loans or they would have to get permission from all of the investors to amend the offering papers and raise the capitalization (which very rarely happens because it dilutes everyone's share and may have already happened once on this show, making a second time even less likely).
However, the operating costs of the show in previews are typically NOT part of the production budget. The show needs to pay for its basic weekly operating costs from the outset. I haven't looked back at the numbers but it seems to me that the show has been breaking even on that front from week to week.
To be clear, our conclusions are the same -- if the show is costing them $1.5M/week in previews and they're making only $1M, that extra $500K per week needs to be accounted for somewhere. But I just wanted to give a bit more detail on the nature of theatrical budgeting/accounting and explain that it's probably only the "extra" $500K per week that needs to be covered in the production budget.
