Ala. Code § 41-10-504: Bonds of Authority Eligible for Investment of Trust Funds.

Any trust fund, where the investment thereof is permitted or required by law, may be invested in bonds issued by the authority. Unless otherwise directed by the court having jurisdiction thereof or the document which is the source of authority, a trustee, executor, administrator, guardian, or one acting in any other fiduciary capacity may, in addition to any other investment powers conferred by law and with the exercise of reasonable business prudence, invest trust funds in the bonds of the authority.
