3. Bonds issued by the State of Israel.
4. Bonds, stocks, or other evidences of indebtedness issued or guaranteed by a corporation organized under the laws of the United States, any state or organized territory of the United States, or the District of Columbia, if:
a. The corporation is listed on any one or more of the recognized national stock exchanges or on the National Market System of the NASDAQ Stock Market and, in the case of bonds only, holds a rating in one of the three highest classifications by a major rating service; and
b. The board of trustees may not invest more than 5 percent of its assets in the common stock or capital stock of any one issuing company, nor may the aggregate investment in any one issuing company exceed 5 percent of the outstanding capital stock of that company or the aggregate of its investments under this subparagraph at cost exceed 50 percent of the assets of the fund.
This paragraph applies to all boards of trustees and participants. However, if a municipality or special fire control district has a duly enacted pension plan pursuant to, and in compliance with, s. 175.351, and the trustees desire to vary the investment procedures, the trustees of such plan must request a variance of the investment procedures as outlined herein only through a municipal ordinance, special act of the Legislature, or resolution by the governing body of the special fire control district; if a special act, or a municipality by ordinance adopted before July 1, 1998, permits a greater than 50-percent equity investment, such municipality is not required to comply with the aggregate equity investment provisions of this paragraph. Notwithstanding any other provision of law, this section may not be construed to take away any preexisting legal authority to make equity investments that exceed the requirements of this paragraph. Notwithstanding any other provision of law, the board of trustees may invest up to 25 percent of plan assets in foreign securities on a market-value basis. The investment cap on foreign securities may not be revised, amended, increased, or repealed except as provided by general law.
