Bar Chart and Performance Table [Heading] How has Nomura Global Listed Real Assets Fund performed?
Performance Narrative [Text Block]
The bar chart and table below provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund’s performance from year to year and the table shows how the Fund’s average annual total returns for the 1-, 5-, and 10-year or lifetime periods compare with those of a broad measure of market performance and additional indices with characteristics relevant to the Fund.
Prior to the close of business on August 19, 2019, the Fund invested primarily in securities of companies principally engaged in the real estate industry. Since the close of business on August 19, 2019, the Fund has been repositioned to invest primarily in listed real assets securities (Repositioning). The historical returns prior to that time do not reflect the Repositioning.
The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. The returns reflect any expense caps in effect during these periods. The returns would be lower without the expense caps. You may obtain the Fund’s most recently available month-end performance by calling 800-523-1918 or by visiting our website at nomuraassetmanagement.com/performance.
