Fla. Stat. § 660.415
In the absence of an express provision to the contrary, when a governing instrument directs, requires, authorizes, or permits investment in United States Government obligations, a trust company, trust department, trustee, or other fiduciary may invest in such obligations, either directly or in the form of securities of, or other interests in, any open-end or closed-end management-type investment company or investment trust registered under the Investment Company Act of 1940, 15 U.S.C. ss. 80a-1 et seq., or a duly authorized common trust fund. However, the portfolio of such investment company, investment trust, or common trust fund is limited to United States Government obligations and repurchase agreements fully collateralized by such United States Government obligations and any such investment company, investment trust, or common trust fund shall take delivery of such collateral either directly or through an authorized custodian.
