The board of university and school lands must be reimbursed from trust proceeds for all reasonable costs and expenses incurred in the management of trust assets and the investment of trust proceeds. Reimbursements to the board must be deposited in the trust fund account from which the expenses were incurred. The net income derived from the assets held in trust must be used for trust purposes. Any assets placed in the trust may be sold, leased, invested, managed, or otherwise disposed of by the board to fulfill the reclamation activities and obligations related to the performance bond. If any of the trust assets include real property, net income from the trust assets must be used in part to pay to the county where the real property is located the same amount that would have been assessed against the real property for real    property taxes if the real property was privately owned. The board may maintain separate accounts in the trust if necessary. The board shall manage all assets in the trust in the same manner that the board manages the board’s other trust assets or as otherwise may be required to satisfy the purposes of this chapter.
