Prospectus [Line Items]
Risk [Text Block]	Disciplined Strategy Risk. The Fund will generally not deviate from its strategy, even during adverse market, economic, political, or other conditions (except to the extent necessary to comply with federal tax laws or other applicable laws). If the Fund is committed to a strategy that is unsuccessful, the Fund will not meet its investment goal. Because the Fund generally will not use certain techniques available to other mutual funds to reduce stock market exposure, the Fund may be more susceptible to general market declines than other mutual funds.
Equity Securities Risk [Member]

Risk [Text Block]	Equity Securities Risk. The Fund’s investments in equity securities are 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. The prices of individual stocks may be negatively affected by poor company results or other factors affecting individual prices, as well as industry and/or economic trends and developments affecting industries or the securities market as a whole.
Factor Based Investing Risk [Member]

Risk [Text Block]	Factor-Based Investing Risk. With respect to a strategy that uses a factor-based process, there can be no assurance that the multi-factor selection process employed by the subadviser will enhance performance. Exposure to investment style factors may detract from performance in some market environments, which may continue for prolonged periods.
Large Cap Companies Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Large-Cap Companies Risk. Large-cap companies tend to go in and out of favor based on market and economic conditions and tend to be less volatile than companies with smaller market capitalizations. In exchange for this potentially lower risk, the Fund’s value may not rise as much as the value of funds that emphasize smaller capitalization 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.

Risk [Text Block]	Market Risk. The Fund’s share price can fall because of weakness in the broad market, a particular industry, or specific holdings or due to adverse social, political or economic developments here or abroad, changes in investor psychology, technological disruptions, or heavy institutional selling and other conditions or events (including, for example, military confrontations, war, terrorism, trade wars, disease/virus outbreaks and epidemics). The prices of individual securities may fluctuate, sometimes dramatically, from day to day. The prices of stocks and other equity securities tend to be more volatile than those of fixed-income securities.
Securities Lending Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Securities Lending Risk. Engaging in securities lending could increase the market and credit risk for Fund investments. The Fund may lose money if it does not recover borrowed securities, the value of the collateral falls, or the value of investments made with cash collateral declines. The Fund’s loans will be collateralized by securities issued or guaranteed by the U.S. Government or its agencies and instrumentalities, which subjects the Fund to the credit risk of the U.S. Government or the issuing federal agency or instrumentality. If the value of either the cash collateral or the Fund’s investments of the cash collateral falls below the amount owed to a borrower, the Fund also may incur losses that exceed the amount it earned on lending the security. Securities lending also involves the risks of delay in receiving additional collateral or possible loss of rights in the collateral if the borrower fails. Another risk of securities lending is the risk that the loaned portfolio securities may not be available to the Fund on a timely basis and the Fund may therefore lose the opportunity to sell the securities at a desirable price.
