Performance Narrative [Text Block]	The bar chart and table provide some indication of the risks of investing in the Portfolio by showing changes in the Portfolio's performance from year to year and by showing how the Portfolio's average annual returns for 1, 5, and 10 years compare with those of a broad-based securities market index that reflects the performance of the overall market applicable to the Portfolio.Past performance does not mean that the Portfolio will achieve similar results in the future.The annual returns and average annual returns shown in the chart and table are after deduction of expenses and do not include Contract charges. If Contract charges were included, the returns shown would have been lower than those shown. Consult your Contract prospectus for information about Contract charges.Annual return information in the bar chart is provided only for Class I shares. Because all of the Portfolio’s shares are invested in the same portfolio of securities, annual returns for Class III shares would be lower because Class III shares do not have the same expenses as Class I shares.Note: Effective May 1, 2025, the Portfolio replaced subadvisers and changed its investment strategy. The performance figures for the Portfolio prior to this date reflect the Portfolio’s former investment operations, policies, strategies and subadvisers. Such performance is not representative of the Portfolio’s current investment operations, policies, strategies, and subadvisers that took effect as of this date, and the Portfolio’s performance after this date could be materially different.
