Ind. Code § 36-9-13-22.5
The authority may operate, maintain, and manage all or any part of a government building or system for the benefit of an eligible entity under a management contract entered into for a period of not more than forty (40) years. The management contract may contain any terms agreed to by the authority and the eligible entity, including a covenant of the eligible entity to pay the authority a monthly fee for costs of operation and maintenance of the government building or system pursuant to the annual budget submitted to the governing body by the authority in accordance with the management contract. The annual budget may contain funds for a working balance and funds for a reserve account for nonrecurring general maintenance, improvement, or replacement costs as provided in the management contract. The eligible entity may enter into the contract through adoption of an ordinance, an order, or a resolution of the entity's governing body or, in the case of a city, a resolution of the board that is responsible for the government building or system. No other approvals of the management contract are required. To the extent provision for payment from other available revenues has not been made and subject to the provisions of the management contract for cancellation or termination, the governing body of the eligible entity that executes a management contract shall annually levy a tax sufficient to produce each year the necessary money with which to pay the management fee required by the budget submitted by the authority. These levies may be reviewed by other bodies vested by law with that power to determine that the annual levies are sufficient to raise the amount required to meet the management fee under the contract.
