| Performance Narrative [Text Block] | The accompanying bar chart and table provide some indication of the risks of investing in the Portfolio. Performance results shown in the bar chart and the performance table below include the performance of the Institutional Class of Lazard Emerging Markets Core Equity Portfolio, another investment company advised by the Investment Manager (the “Predecessor Portfolio”). The assets of the Predecessor Portfolio were transferred to the Portfolio in a tax-free reorganization on October 24, 2025. The performance of the Predecessor Portfolio has not been restated to reflect the annual operating expenses of the Portfolio, which are lower than those of the Predecessor Portfolio. Because the Portfolio has different fees and expenses than the Predecessor Portfolio, the Portfolio would also have had different performance results. Additionally, if the Predecessor Portfolio had operated as an ETF, its performance may have differed. The bar chart shows the Portfolio’s year-by-year performance and average annual performance compared to that of a broad measure of market performance over the past 10 calendar years. Updated performance information for the Portfolio is available at www.lazardassetmanagement.com or by calling (800) 823-6300. The Portfolio’s past performance (before and after taxes) is not necessarily an indication of how the Portfolio will perform in the future. |
