There is created a Mississippi Affordable College Savings Trust Fund as an instrumentality of the state to be administered by the Treasury Department. The MACS Trust Fund shall consist of state appropriations, monies acquired from other governmental or private sources and money remitted in accordance with savings trust agreements and shall receive and hold all payments, contributions and deposits intended for it as well as gifts, bequests, endowments or federal, state or local grants and any other public or private source of funds and all earnings on the fund until disbursed as provided under this section. The amounts on deposit in the trust fund shall not constitute property of the state. Amounts on deposit in the trust fund may not be commingled with state funds, and the state may have no claim to or interest in such funds. Savings trust agreements or any other contract entered into by or on behalf of the trust do not constitute a debt or obligation of the state, and no account owner is entitled to any amounts except for those amounts on deposit in or accrued to their account. The MACS Trust Fund shall continue in existence as long as it holds any funds belonging to an account owner or otherwise has any obligations to any person or entity until its existence is terminated by the Legislature and remaining assets on deposit in the fund are returned to account owners or transferred to the state in accordance with unclaimed property laws.
