 fund’s investment portfolio. When-Issued and Delayed-Delivery Transactions Risk.The Fund may invest in securities on a “when-issued” or “delayed-delivery” basis. When-issued and delayed-delivery transactions may involve an element of risk because no interest accrues on the securities prior to settlement and, because securities are subject to market fluctuations, the value of the securities at time of delivery may be less (or more) than their cost. A separate account of the Fund will be established with its custodian consisting of cash equivalents or liquid securities having a market value at all times at least equal to the amount of any delayed payment commitment.
