A person who has a claim against the estate of a state trust company in liquidation must file proof of claim pursuant to rules adopted by the state banking board. The priority of disposition of assets from the estate of a state trust company must be in accordance with the order of each class as provided by this section. Every claim in each class must be paid in full, or adequate funds must be retained for that payment, before the members of the next class receive any payment. A subclass may not be established within a class, except for a preference or subordination within a class expressly created by contract or other instrument in the articles of association. Assets must be distributed in the following order of priority: administrative expenses; approved claims of secured trust deposits; approved claims of secured creditors; approved claims by beneficiaries insufficient to satisfy all fiduciary claims to commingled fiduciary funds or missing fiduciary property and approved claims of clients of the state trust company; other approved claims of general creditors not falling within a higher priority under this section; approved claims of a type described above that were not filed within the period prescribed; and claims of capital note or debenture holders or holders of similar obligations and proprietary claims of shareholders, participants, or other owners accorded the terms established by issue, class, or series. After completion of the liquidation, any unclaimed property remaining in the hands of the receiver must be considered abandoned property.
