| Investment objectives | ||||||||||||||||||||||||||||||||
The fund has two primary investment objectives. It seeks (1) to provide a level of current income that exceeds the average yield on U.S. stocks generally and (2) to provide a growing stream of income over the years. | ||||||||||||||||||||||||||||||||
| The fund’s secondary objective is to provide growth of capital. | ||||||||||||||||||||||||||||||||
| Fees and expenses of the fund | ||||||||||||||||||||||||||||||||
This table describes the fees and expenses that you may pay if you buy, hold and sell an interest in Class 1A shares of the fund. You may pay other fees, such as insurance contract fees and expenses, which are not reflected in the tables and examples below. If insurance contract fees and expenses were reflected, expenses shown would be higher. | ||||||||||||||||||||||||||||||||
| Annual fund operating expenses (expenses that you pay each year as a percentage of the value of your investment) | ||||||||||||||||||||||||||||||||
| ||||||||||||||||||||||||||||||||
| Example | ||||||||||||||||||||||||||||||||
This example is intended to help you compare the cost of investing in Class 1A shares of the fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the fund 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 fund’s operating expenses remain the same. The example does not reflect insurance contract expenses. If insurance contract expenses were reflected, expenses shown would be higher. The example reflects the fee waiver described above through the expiration date of such waiver and total annual fund operating expenses thereafter. No sales charge (load) or other fees are charged by the fund upon redemption, so you would incur these hypothetical costs whether or not you were to redeem your shares at the end of the given period. | ||||||||||||||||||||||||||||||||
| Although your actual costs may be higher or lower, based on these assumptions your costs would be: | ||||||||||||||||||||||||||||||||

| Portfolio turnover | ||||||||||||||||||||||||||||||||
The fund 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 fund operating expenses or in the example, affect the fund’s investment results. During the most recent fiscal year, the fund’s portfolio turnover rate was 149% of the average value of its portfolio. | ||||||||||||||||||||||||||||||||
| Principal investment strategies | ||||||||||||||||||||||||||||||||
The fund normally invests at least 90% of its assets in income-producing securities (with at least 50% of its assets in common stocks and other equity securities). The fund invests primarily in a broad range of income-producing securities, including common stocks and bonds. In seeking to provide a level of current income that exceeds the average yield on U.S. stocks, the fund generally looks to the average yield on stocks of companies listed on the S&P 500 Index. The fund may also invest significantly in common stocks, bonds and other securities outside the United States. The investment adviser uses a system of multiple portfolio managers in managing the fund’s assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers. The fund relies on the professional judgment of its investment adviser to make decisions about the fund’s portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued securities that, in its opinion, represent good, long-term investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities. | ||||||||||||||||||||||||||||||||

| Investment results | ||||||||||||||||||||||||||||||||
The following bar chart shows how the investment results of the Class 1A shares of the fund have varied from year to year, and the following table shows how the fund’s average annual total returns for various periods compare with a broad measure of securities market results and other applicable measures of market results. This information provides some indication of the risks of investing in the fund. The MSCI All Country World Index reflects the equity market sectors in which the fund invests. Results reflect dividends gross of withholding taxes through December 31, 2000, and dividends net of withholding taxes thereafter. The Bloomberg U.S. Aggregate Index represents the U.S. investment-grade fixed-rate bond market. Past investment results (before and after taxes) are not predictive of future investment results. Figures shown reflect fees and expenses associated with an investment in the fund, but do not reflect insurance contract fees and expenses. If insurance contract fees and expenses were included, results would have been lower.

The following bar chart shows how the investment results of the Class 1 shares of the fund have varied from year to year, and the following table shows how the fund’s average annual total returns for various periods compare with a broad measure of securities market results. | ||||||||||||||||||||||||||||||||
| Calendar year total returns* | ||||||||||||||||||||||||||||||||
| ||||||||||||||||||||||||||||||||
* Lifetime returns are from July 5, 2001, the date the fund began investment operations. Class 1A shares began investment operations on January 6, 2017; therefore, returns for the fund prior to that date assume a hypothetical investment in Class 1 shares, but reflect the .25% annual expense that applies to Class 1A shares and is described in the “Fund expenses” section of the prospectus. Returns for Class 1 shares are comparable to those of Class 1A shares because both classes invest in the same portfolio of securities. | ||||||||||||||||||||||||||||||||
