The Portfolio’s investment goal is total return (including capital appreciation and current income).

Fees and Expenses of the Portfolio

This table describes the fees and expenses that you may pay if you buy and hold shares of the Portfolio. The Portfolio’s annual operating expenses do not reflect the separate account fees charged in the variable annuity or variable life insurance policy (“Variable Contracts”), as defined herein, in which the Portfolio is offered. If the separate account’s 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.

Annual Portfolio Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

	Class 1		Class 2			Class 3
Management Fees		0.60%		0.60	%		0.60	%
Service (12b-1) Fees		None		0.15	%		0.25	%
Other Expenses		0.04%		0.04	%		0.04	%
Total Annual Portfolio Operating Expenses		0.64%		0.79	%		0.89	%

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 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. 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:

	1 Year		3 Years		5 Years		10 Years
Class 1 Shares	$	65	$	205	$	357	$	798
Class 2 Shares		81		252		439		978
Class 3 Shares		91		284		493		1,096

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 68% of the average value of its portfolio.

Principal Investment Strategies of the Portfolio

The Portfolio attempts to achieve its goal by investing in thirty high dividend yielding common stocks selected quarterly from the Dow Jones Industrial Average and the broader market.

The Portfolio employs a “buy and hold” strategy that quarterly selects the following 30 stocks: (1) the 10 highest yielding common stocks in the Dow Jones Industrial Average (“DJIA”) and (2) the 20 other highest yielding stocks of the 400 largest industrial companies in the U.S. markets that have capitalizations of at least $1 billion and have received one of the two highest rankings from an independently published common stock ranking service on the basis of growth and stability of earnings and dividends. The stocks in the Portfolio will not change over the course of each quarter, even if there are adverse developments concerning a particular stock, an industry, the economy or the stock market generally.

The first 10 stocks represent the 10 highest yielding common stocks in the DJIA. This is popularly known as the “Dogs of the Dow” theory and was popularized in the early 1990’s. The strategy seeks to capitalize on relative undervaluation as defined by dividend yield. In an attempt to minimize volatility and maximize performance, the adviser has expanded the strategy by 20 stocks to create the Portfolio.

Due to purchases and redemptions of Portfolio shares during the year and changes in the market value of the stocks held by the Portfolio, it is likely that the weightings of the stocks in the Portfolio will fluctuate throughout the course of the year. This may result in the Portfolio investing more than 25% of its assets in the securities of issuers in the same industry, to the extent such investments are selected according to the Portfolio’s stock selection criteria.

Principal Risks of Investing in the Portfolio

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. As with any mutual fund, there is no guarantee that the Portfolio will be able to achieve its investment goal. If the value of the assets of the Portfolio goes down, you could lose money.

The following is a summary description 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.

Disciplined Strategy Risk. The Portfolio will not deviate from its strategy (except to the extent necessary to comply with federal tax laws or other applicable laws). If the Portfolio is committed to a strategy that is unsuccessful, the Portfolio will not meet its investment goal. Because the Portfolio generally will not use certain techniques available to other mutual funds to reduce stock market exposure (e.g., derivatives), the Portfolio may be more

susceptible to general market declines than other mutual funds.

Sector Risk. Sector risk is the possibility that a certain sector may underperform other sectors or the market as a whole. As a Portfolio allocates more of its portfolio holdings to a particular sector, the Portfolio’s performance will be more susceptible to any economic, business or other developments which generally affect that sector.

Market Risk. The Portfolio’s share price can fall because of weakness in the broad market, a particular industry, or specific holdings. The market as a whole can decline for many reasons, including adverse political or economic developments here or abroad,

changes in investor psychology, or heavy institutional selling. In addition, the subadviser’s assessment of companies 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 (“SAAMCo”) serves as investment adviser that are managed as “fund 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 Risk/Return Bar Chart and Table illustrate the risks of investing in the Portfolio by showing changes in the Portfolio’s performance from calendar year to calendar year and comparing the Portfolio’s average annual returns to those of the S&P 500^® Index. 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.

(Class 1 Shares)

During the 10-year period shown in the bar chart, the highest return for a quarter was 16.29% (quarter ended September 30, 2009) and the lowest return for a quarter was -19.91% (quarter ended December 31, 2008). The year-to-date calendar return as of March 31, 2016 was 7.95%.

Tax Information

The Portfolio will not be subject to federal income tax on the net investment company taxable income or net capital gains distributed to shareholders as ordinary income dividends or capital gain dividends; however, you may be subject to federal income tax (and a federal Medicare tax of 3.8% that applies to net investment income, including taxable annuity payments, if applicable) upon withdrawal from such tax deferred arrangements.

Payments to Broker-Dealers and

Other Financial Intermediaries

The Portfolio is not sold directly to the general public but instead is offered as an underlying investment option for the Variable Contracts. The Portfolio and its related companies may make payments to the sponsoring insurance company (or its affiliates) for distribution and/or other services. These payments create a conflict of interest as they may be a factor that the insurance company considers in including the 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.
