Fees and Expenses of the Portfolio
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 below do not reflect the separate account fees charged in the variable annuity or variable life insurance policy (“Variable Contracts”) in which the Portfolio is offered. If separate account fees were shown, the Portfolio’s annual operating expenses would be higher. Please see your Variable Contract prospectus for more details on the separate account fees.

Expense Example
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 or hold all of your shares at the end of those periods. 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 incorporates any applicable fee waiver and/or expense limitation arrangements for only the first year). The Example does not reflect charges imposed by the Variable Contract. If the Variable Contract fees were reflected, the expenses would be higher. See the Variable Contract prospectus for information on such charges. Although your actual costs may be higher or lower, based on these assumptions and the net expenses shown in the fee table, your costs would be:

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual portfolio operating expenses or in the Example, affect the Portfolio’s performance.
During the most recent fiscal year, the Portfolio’s portfolio turnover rate was 66% of the average value of its portfolio.
Principal Investment Strategies of the Portfolio
The Portfolio attempts to achieve its goal by investing primarily in common stocks or securities with common stock characteristics of U.S. and foreign issuers that demonstrate the potential for appreciation and engaging in transactions in foreign currencies. Under normal circumstances, at least 80% of the Portfolio’s assets will be invested in equity securities. The Portfolio may invest in equity securities of companies in any market

capitalization range. The Portfolio will invest significantly in foreign securities, which may include securities of issuers located in emerging markets.
In managing the Portfolio, the subadviser adheres to a disciplined process for stock selection and portfolio construction. A proprietary multi-factor model is used to quantitatively rank securities in the Portfolio’s investment universe on the basis of value, quality and growth (momentum) factors. Value is measured by valuation metrics based on earnings and cash flow, while quality is assessed by focusing on operational, management and earnings quality. Momentum is captured by factors such as relative price strength and earnings revisions. Securities held in the Portfolio that have become over-valued and/or whose quality and growth (momentum) signals have deteriorated materially may be sold. Securities that are sold are generally replaced with the most attractive securities, on the basis of the subadviser’s disciplined investment process.
The portfolio construction process controls for sector and industry weights, number of stocks held, and position size. Risk or factor exposures are actively managed through portfolio construction.
The frequency with which the Portfolio buys and sells securities will vary from year to year, depending on market conditions. The Portfolio may use an active trading strategy to achieve its objective.
Principal Risks of Investing in the Portfolio
As with any mutual fund, there can be no assurance that the Portfolio’s investment goal will be met or that the net return on an investment in the Portfolio will exceed what could have been obtained through other investment or savings vehicles. Shares of the Portfolio are not bank deposits and are not guaranteed or insured by any bank, government entity or the Federal Deposit Insurance Corporation. If the value of the assets of the Portfolio goes down, you could lose money.
The following is a summary of the principal risks of investing in the Portfolio.
Equity Securities Risk. The Portfolio invests principally in equity securities and is therefore subject to the risk that stock prices will fall and may underperform other asset classes. Individual stock prices fluctuate from day-to-day and may decline significantly.
Foreign Currency Risk. The value of the Portfolio’s foreign investments may fluctuate due to changes in currency exchange rates. A decline in the value of foreign currencies relative to the U.S. dollar generally can be
expected to depress the value of the Portfolio’s non-U.S. dollar-denominated securities.
Large-Cap Companies Risk. Large-cap companies tend to be less volatile than companies with smaller market capitalizations. In exchange for this potentially lower risk, the Portfolio’s value may not rise as much as the value of portfolios that emphasize smaller companies. Larger, more established companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rate of successful smaller companies, particularly during extended periods of economic expansion.
Small- and Mid-Cap Companies Risk. Companies with smaller market capitalizations (particularly under $1 billion depending on the market) tend to be at early stages of development with limited product lines, operating histories, market access for products, financial resources, access to new capital, or depth in management. It may be difficult to obtain reliable information and financial data about these companies. Consequently, the securities of smaller companies may not be as readily marketable and may be subject to more abrupt or erratic market movements than companies with larger capitalizations. Securities of medium-sized companies are also subject to these risks to a lesser extent.
Foreign Investment Risk. The Portfolio’s investments in the securities of foreign issuers or issuers with significant exposure to foreign markets involve additional risk. Foreign countries in which the Portfolio invests may have markets that are less liquid, less regulated and more volatile than U.S. markets. The value of the Portfolio’s investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable government actions, and political or financial instability and other conditions or events (including, for example, military confrontations, war, terrorism, sanctions, disease/virus, outbreaks and epidemics). Lack of relevant data and reliable public information may also affect the value of these securities. The risks of foreign investments are heightened when investing in issuers in emerging market countries.
Emerging Markets Risk. Risks associated with investments in emerging markets may include: delays in settling portfolio securities transactions; currency and capital controls; greater sensitivity to interest rate changes; pervasive corruption and crime; exchange rate volatility; inflation, deflation or currency devaluation; violent military or political conflicts; confiscations and other government restrictions by the United States or other governments; and government instability. As a

result, investments in emerging market securities tend to be more volatile than investments in developed countries.
Growth Stock Risk. Growth stocks may lack the dividend yield associated with value stocks that can cushion total return in a bear market. Also, growth stocks normally carry a higher price/earnings ratio than many other stocks. Consequently, if earnings expectations are not met, the market price of growth stocks will often decline more than other stocks.
Value Investing Risk. The subadviser’s judgment that a particular security is undervalued in relation to the company’s fundamental economic value may prove incorrect.
Active Trading Risk. The Portfolio may engage in frequent trading of securities to achieve its investment goal. Active trading may result in high portfolio turnover and correspondingly greater brokerage commissions and other transaction costs, which will be borne directly by the Portfolio and could affect its performance. During periods of increased market volatility, active trading may be more pronounced.
Issuer Risk. The value of a security may decline for a number of reasons directly related to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods and services.
Management Risk. The Portfolio is subject to management risk because it is an actively-managed investment portfolio. The Portfolio’s portfolio managers apply investment techniques and risk analyses in making investment decisions, but there can be no guarantee that these decisions or the individual securities selected by the portfolio managers will produce the desired results.
Market Risk. The Portfolio’s share price or the market as a whole can decline for many reasons or be adversely affected by a number of factors, including, without limitation: weakness in the broad market, a particular industry, or specific holdings; adverse political, regulatory or economic developments in the United States or abroad; changes in investor psychology; heavy institutional selling; military confrontations, war, terrorism and other armed conflicts, disease/virus outbreaks and epidemics; recessions; taxation and international tax treaties; currency, interest rate and price fluctuations; and other
conditions or events. In addition, the subadviser’s assessment of securities held in the Portfolio may prove incorrect, resulting in losses or poor performance even in a rising market.
Affiliated Fund Rebalancing Risk. The Portfolio may be an investment option for other mutual funds for which SunAmerica Asset Management, LLC (“SunAmerica”) serves as investment adviser that are managed as “funds of funds.” From time to time, the Portfolio may experience relatively large redemptions or investments due to the rebalancing of a fund of funds. In the event of such redemptions or investments, the Portfolio could be required to sell securities or to invest cash at a time when it is not advantageous to do so.
Performance Information
The following bar chart illustrates the risks of investing in the Portfolio by showing changes in the Portfolio’s performance from calendar year to calendar year and the table compares the Portfolio’s average annual returns to those of the MSCI World Index (net) (a broad-based securities market index), which is relevant to the Portfolio because it has characteristics similar to the Portfolio’s investment strategies. Fees and expenses incurred at the contract level are not reflected in the bar chart or table. If these amounts were reflected, returns would be less than those shown. Of course, past performance is not necessarily an indication of how the Portfolio will perform in the future.

Purchases and Sales of Portfolio Shares
Shares of the Portfolios may only be purchased or redeemed through Variable Contracts offered by the separate accounts of participating life insurance companies and by other portfolios of the Trust and Seasons Series Trust. Shares of a Portfolio may be
purchased and redeemed each day the New York Stock Exchange is open, at the Portfolio’s net asset value determined after receipt of a request in good order.
The Portfolios do not have any initial or subsequent investment minimums. However, your insurance company may impose investment or account minimums. Please consult the prospectus (or other offering document) for your Variable Contract which may contain additional information about purchases and redemptions of Portfolio shares.
Tax Information
The Portfolios will not be subject to U.S. federal income tax so long as they qualify as regulated investment companies and distribute their income and gains each year to their shareholders. However, contractholders may be subject to U.S. federal income tax (and a U.S. federal Medicare tax of 3.8% that applies to net investment income, including taxable annuity payments, if applicable) upon withdrawal from a Variable Contract. Contractholders should consult the prospectus (or other offering document) for the Variable Contract for additional information regarding taxation.
Payments to Broker-Dealers and
Other Financial Intermediaries
The Portfolios are not sold directly to the general public but instead are offered as an underlying investment option for Variable Contracts and to other portfolios of the Trust and Seasons Series Trust. A Portfolio and its related companies may make payments to the sponsoring insurance company (or its affiliates) for distribution and/or other services. These payments may create a conflict of interest as they may be a factor that the insurance company considers in including a Portfolio as an underlying investment option in the Variable Contract. The prospectus (or other offering document) for your Variable Contract may contain additional information about these payments.
