Strategy Narrative [Text Block]	The fund invests primarily in common stocks and seeks to invest in companies that appear to offer superior opportunities for growth of capital. The fund normally invests at least 80% of its assets in growth investments. For purposes of this policy, the investment adviser currently defines growth investments as investments in companies that appear to offer superior opportunities for growth of capital. In making this determination, the investment adviser considers companies to offer superior opportunities for growth of capital if they are included in the Russell 3000 Growth Index, MSCI ACWI IMI Growth Index, or S&P Super Composite Growth Index in the current or prior year, if they exhibit the potential for growth based on factors such as historical or projected revenue, free cash flow, or alternative cash flow or valuation metrics for certain industries, or if the investment adviser expects the company to contribute to the fund’s long-term growth of capital based on factors such as whether the company is attractively valued or is positioned to benefit from innovation, economic growth, increasing consumer demand, or a turnaround in business conditions. The fund may invest up to 25% of its assets outside the United States. The fund is nondiversified, which means it may invest a greater portion of its assets in fewer issuers than would otherwise be the case. The investment adviser uses a system of multiple portfolio managers in managing assets. Under this approach, a portfolio is divided into segments managed by individual managers. For more information regarding the investment process of the fund, see the “Management and organization” section of this prospectus. 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 companies 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 Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.
