Performance Narrative [Text Block]	The following information is intended to help you understand the risks of investing in the Portfolio. The following bar chart shows the changes in the Portfolio's performance from year to year, and the table compares the Portfolio's performance to the performance of a broad-based securities market index and additional indices with investment characteristics similar to those of the Portfolio for the same period. The Portfolio's performance information reflects applicable fee waivers and/or expense limitations in effect during the period presented. Absent such fee waivers/expense limitations, if any, performance would have been lower. The bar chart shows the performance of the Portfolio's Class ADV shares. Performance for other share classes would differ to the extent they have differences in their fees and expenses. The Class R6 shares performance shown for the period prior to their inception date is the performance of Class I shares without adjustment for any differences in expenses between the two classes. If adjusted for such differences, returns would be different.Performance shown in the bar chart and in the Average Annual Total Returns table does not include insurance-related charges imposed under a Variable Contract or expenses related to a Qualified Plan. If these charges or expenses were included, performance would be lower. Thus, you should not compare the Portfolio's performance directly with the performance information of other investment products without taking into account all insurance-related charges and expenses payable under your Variable Contract or Qualified Plan. The Portfolio's past performance is no guarantee of future results.The Portfolio’s performance prior to February 1, 2022 reflects returns achieved pursuant to different principal investment strategies. If the Portfolio’s current strategies had been in place for the prior periods, the performance information shown would have been different.
