Performance Narrative [Text Block] | The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns compare with those of a broad measure of market performance and an additional index over time. Sales loads, if any, are not reflected in the bar chart. If they were, returns would be less than those shown. The Fund has selected the MSCI World Index (Net) to represent a broad measure of market performance. The table also includes the average annual returns of the FTSE Global Core Infrastructure 50/50 Index (Net), which is generally representative of the market sectors or types of investments in which the Fund invests. Index returns reflect no deductions for fees, expenses or taxes, except for foreign withholding taxes where applicable. Performance data for the classes varies based on differences in their fee and expense structures. Performance data is not shown for classes with less than one calendar year of performance. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Please visit newyorklifeinvestments.com/funds for more recent performance information. Effective February 21, 2020, the Voya CBRE Global Infrastructure Fund (the "Predecessor Fund") was reorganized into the Fund. As accounting successor to the Predecessor Fund, the Fund has assumed the Predecessor Fund’s historical performance. Therefore, the performance information shown below includes that of the Predecessor Fund, which had a different fee structure than the Fund. Past performance may have been different if the Fund’s current fee structure had been in place during the period. |
