Expense Example Narrative [Text Block]	This Example is intended to help you compare the cost of investing in 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 (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 separate account 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 [Text Block]	The Fund, which operates as a fund-of-funds, does not pay transaction costs when it buys and sells shares of the Underlying Funds (or “turns over” its portfolio). An Underlying Fund pays transaction costs, such as commissions, when it turns over its portfolio and 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 performance of both the Underlying Fund and the Fund. During the most recent fiscal year, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio.
