Performance. The chart and table below show how The U.S. Equity Portfolio has performed, and how its performance has varied, from year to year. The bar chart shows returns on a before-tax basis and gives some indication of risk by showing changes in the Portfolio’s yearly performance for each of the last ten full calendar years. The table accompanying the bar chart compares the Portfolio’s performance over time on a before and after-tax basis to that of a broad based market index. As of April 17, 2024, the Portfolio changed its investment strategies and certain investment policies. In view of these changes, the Portfolio’s performance record prior to this period might be less pertinent for investors considering whether to purchase shares of the Portfolio. Of course, past performance, before and after taxes, does not indicate how the Portfolio will perform in the future.
