The Portfolio seeks to provide total return.

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Portfolio. The table and the example do not include any fees or sales charges imposed by your variable annuity or variable life insurance contract. If they were included, your costs would be higher. Please refer to your variable contract prospectus for information on the separate account fees and expenses associated with your contract.

(1)  The "Other Expenses" for Class III shares are based on estimated amounts.

(2)  Acquired Fund Fees and Expenses are the indirect cost of investing in other investment companies, the costs of which will not be included in the Portfolio's financial statements. The operating expenses in this fee table will not correlate to the expense ratio in the Portfolio's financial highlights because the financial statements include only the direct operating expenses incurred by the Portfolio.

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. You would pay the same expenses if you did not redeem your shares. However, each variable contract and separate account involves fees and expenses that are not included in the Example. If these fees and expenses were included in the Example, your overall expenses would be higher. The Example also assumes that your investment has a 5% return each year and that the Portfolio's operating expenses remain the same (except that the Example reflects any applicable contractual fee waivers/expense reimbursement arrangements for only the first year). Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities or instruments (or "turns over" its portfolio). These costs, which are not reflected in annual portfolio operating expenses or in the Example, affect the Portfolio's performance. A higher portfolio turnover rate may indicate higher transaction costs. During the most recent fiscal year ended December 31, 2025, the Portfolio's portfolio turnover rate was 44% of the average value of its portfolio.

Under normal market conditions, the Portfolio seeks to achieve its investment objective primarily through investing at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in a diversified group of underlying exchange-traded funds ("Underlying ETFs") that are affiliated with the Portfolio's sub-adviser, BlackRock Investment Management, LLC ("BlackRock" or the "Sub-Adviser").

Under normal market conditions, the Sub-Adviser allocates approximately 40% to 80% of the Portfolio's assets to Underlying ETFs that invest primarily in equity securities of both U.S. and non-U.S. issuers and 20% to 60% of the Portfolio's assets to Underlying ETFs that invest primarily in fixed-income securities and/or cash alternatives in both U.S. and non-U.S. markets. The Portfolio incorporates a global tactical asset allocation strategy that, under normal circumstances, seeks to adjust allocations to asset classes that BlackRock deems to be attractive investments over the short to intermediate term. This strategy seeks to enhance the total return and manages portfolio risk at the aggregate level. Modifications in the allocations to the ETFs are based on techniques that may include technical, qualitative, quantitative and momentum analysis of the market. The mix of ETFs will vary with market conditions and BlackRock's assessment of the ETFs' relative attractiveness as investment opportunities. Certain ETFs' investments will focus on investments in securities listed on domestic and foreign equity exchanges with growth and value styles, including, small-, mid- and large-cap issuers, and on investments in domestic and foreign fixed-income instruments including U.S. treasuries, mortgage- and asset-backed securities, corporate loans, distressed securities, inflation-indexed instruments, corporate bonds, sovereign and emerging market debt. An ETF may invest a large percentage of its assets in indices located in a single country, a small number of countries, or a particular geographic region. In addition, the Underlying ETFs may invest in lower quality debt securities. Such securities are sometimes referred to as "junk bonds." An Underlying ETF may integrate environmental, social and governance ("ESG") factors into its investment selection process and/or screen out particular companies and industries based on certain ESG related criteria. An Underlying ETF may also seek to deliver exposure to certain style factors (i.e. quality, value, momentum, size, minimum volatility).

The Portfolio may also invest in securities and derivative contracts, including indexes, swap agreements, futures, options, currency forwards, and U.S. Treasury securities, and cash equivalents including, without limitation, commercial paper, and time deposits, as determined by the Sub-Adviser.

The bar chart and performance table below show the variability of the Portfolio's returns, which is some indication of the risks of investing in the Portfolio. The bar chart shows performance of the Portfolio's Class I shares for each full calendar year since the Portfolio's inception and the table shows how the average annual total returns of the Portfolio's Class I shares compared with the returns of two indexes. The S&P Target Risk^®​ Growth Index serves as the Portfolio's performance index because the Adviser believes it is more representative of the Portfolio's investment strategy. The MSCI All Country World Index ("MSCI ACWI Index") (Net Total Return, USD) serves as the Portfolio's regulatory index and provides a broad measure of market performance. The performance in the bar chart and the table does not include the effect of variable contract charges. If variable contract charges had been included, performance would have been lower. Because all of the Portfolio's shares are invested in the same portfolio of securities, returns for the Portfolio's Class II shares differ only to the extent that the classes do not have the same expenses. You should be aware that the Portfolio's past performance may not be an indication of how the Portfolio will perform in the future.
