The rental pool only calculates the rental income and does not take into account the operational costs of the park. The pool only distributes the realised rental turnover among owners based on their pool share.
The risk that the operational costs of the park exceed the income allocated to EuroParcs from the rental pool lies entirely with EuroParcs as park manager.
The risk you run as an owner depends on your user model. With Investment Ownership, Holiday Ownership and Premium Ownership, you receive the predetermined returns. This payment is substantive of the rental income realised on your property (and on the park). With the Rental Ownership model, you receive a predetermined percentage of your pool share. Your pool share depends on the rental income in the rental pool.
