The following information may give some indication of the risks of investing in the Fund. The Fund is the successor to the Predecessor International Equity Fund, a mutual fund with identical investment objectives, policies, and restrictions, as a result of the reorganization of the Predecessor International Equity Fund into the Fund on April 24, 2026. The performance provided in the bar chart and table is that of the Predecessor International Equity Fund. The bar chart illustrates how the Predecessor International Equity Fund’s average annual returns have varied from year to year for the past ten calendar years. The table below illustrates how the Predecessor International Equity Fund’s average annual total returns compare with those of a broad measure of market performance, the MSCI ACWI (All Country World Index) ex USA IMI Index. The performance prior to December 12, 2018 reflects the performance results obtained under a different sub-adviser that used different investment strategies. Had the current sub-adviser and investment strategies been in place during that period, the performance results may have been different. The performance information shown here does not reflect fees that are paid by the insurance company separate accounts that invest in the Fund. Inclusion of those fees would reduce the total return figures for all periods. The Predecessor International Equity Fund’s past performance does not necessarily indicate how the Fund will perform in the future.
