For purposes of this policy, global securities include: common stock, depositary receipts, real estate securities, master limited partnerships (MLPs) (up to a maximum of 25% of the fund's net assets), preferred stock, rights, warrants, exchange-traded funds (ETFs), and debt securities (up to a maximum of 20% of the fund's net assets).
