Nobody except the resorts and Alterra execs know. I have no secret view or any extra knowledge into it.
The contracts with the partners are all hidden and not public. Even Public companies like VR don't have the contract details public.
So it's all speculation. With global event like this, I would also assume all the contracts are up for a mutual modification anyway to discuss how the deferred money or other changes gets split up. Perhaps some of these negotiations is why there is this delay in additional pass change announcements?
Even in a regular year, they could've structured it both ways, and either way would make sense.
Everybody could share the pie preset regardless of pass skierdays that actually go. Or they could have it a resort gets paid based on skierday; or a blend. There could be different contracts with different partners. The # of partnerships are relatively small so I'd imagine each is customized and negotiated and fought over.
My guess is for the most part, the major selling point of the network is to smooth out the weather and seasonal ups/downs due to Geo; so I'd assume in the majority of these contracts the resorts gets about the same cut of pass-revenue no matter how many passholders show up(but the numbers may leverage a better future contract).
A resort could also get near nothing from the pass sale money, but be expected to make all the money on all the other things the skier spends on during a visit.
These are big corporations, you don't need to give them your money as charity, and I don't believe the pass money really trickle down to the local economy. Just like pro sports team, the big TV money gets split evenly to the teams no matter; the local concessions and local tix sales go to the team (which is still a big business). For the actual local economy, it's just the scraps of the parking, hotels, bars, and staff paychecks. If you want to pump some money in , then I'd suggest to directly buy some stuff from a business in that area, or donate to a local charity; no need for mental gymnastics that your pass money is going to trickle down to help someone.
