    <oef:StrategyPortfolioConcentration contextRef="c1" id="ixv-38">Under normal market conditions,
the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in growth securities (the &#x201c;80% Policy&#x201d;).
Growth securities are common stocks of companies that are expected, over the long term, to have earnings growth that is faster than the
growth of the U.S. economy, or companies that are constituents of the Russell 1000&#xae; Growth Index (the &#x201c;Index&#x201d;).
The Fund invests in common stocks of approximately 20 to 35 companies. The Fund will normally invest in common stocks of companies having
market capitalizations that rank among the top 1,000 U.S. companies. The Fund may invest in U.S. dollar-denominated securities of foreign
companies that trade on U.S. exchanges or in the over-the-counter market (including depositary receipts, such as American Depositary
Receipts (&#x201c;ADRs&#x201d;), which are either sponsored or unsponsored, that evidence ownership in underlying foreign stocks) and in
publicly traded real estate investment trusts (&#x201c;REITs&#x201d;). The Fund is &#x201c;non-diversified&#x201d; and may invest, a greater
percentage of its assets in the securities of a single issuer than a &#x201c;diversified&#x201d; fund. The Fund may also lend its securities.</oef:StrategyPortfolioConcentration>
