The fund normally allocates its assets among multiple investment strategies employed by BNY Mellon Investment Adviser, Inc. (BNYIA) and affiliated and unaffiliated sub-advisers that invest primarily in equity securities issued by mid cap companies. The fund is designed to provide exposure to various mid cap equity portfolio managers and investment strategies and styles. The fund may invest up to 15% of its net assets in the equity securities of foreign issuers. BNYIA determines the investment strategies and sets the target allocations and ranges. The investment strategies and the fund's targets and ranges (expressed as a percentage of the fund's investable assets) for allocating its assets among the investment strategies as of the date of this prospectus were as follows: Investment Strategy Target Range Mid Cap Tax-Sensitive Core Strategy 40% 0% to 50% Mid Cap Value Strategy 15% 0% to 30% Mid Cap Growth Strategy 15% 0% to 30% Boston Partners Mid Cap Value Strategy 15% 0% to 30% Geneva Mid Cap Growth Strategy 15% 0% to 30% The Mid Cap Tax-Sensitive Core Strategy is employed by BNYIA, the Mid Cap Value Strategy and the Mid Cap Growth Strategy are employed by Newton Investment Management North America, LLC (NIMNA), an affiliate of BNYIA, and the Boston Partners Mid Cap Value Strategy and the Geneva Mid Cap Growth Strategy are employed by unaffiliated sub-advisers, namely, Boston Partners Global Investors, Inc. (Boston Partners) and Geneva Capital Management LLC (GCM), respectively. BNYIA has the discretion to change the investment strategies, including whether to implement a strategy employed by BNYIA or a sub-adviser, and the target allocations and ranges when BNYIA deems it appropriate without notice to or approval by shareholders. The portion of the fund's assets allocated to the Mid Cap Tax-Sensitive Core Strategy normally is invested primarily in equity securities of mid cap companies included in the Russell Midcap Index. In selecting securities for the Mid Cap Tax-Sensitive Core Strategy, the portfolio manager uses an optimization program to establish portfolio characteristics and risk factors that the portfolio manager determines are within an acceptable range of the Russell Midcap Index. The Mid Cap Tax-Sensitive Core Strategy does not seek to add value through active security selection, nor does it target index replication. The portfolio manager seeks to actively and opportunistically realize capital gains and/or losses within this strategy as determined to be appropriate to improve the tax-sensitivity of the portfolio's investment performance. The Mid Cap Tax-Sensitive Core Strategy may realize losses to offset gains incurred as a result of more closely aligning the portfolio with the characteristics of the Russell Midcap Index, or to allow more flexibility for offsetting gains incurred through subsequent rebalancing of the portfolio. In addition, the Mid Cap Tax-Sensitive Core Strategy may realize capital losses to offset any realized capital gains of the fund's other investment strategies. NIMNA is the fund's sub-adviser responsible for the portion of the fund's assets allocated to the Mid Cap Value Strategy. The portion of the fund's assets allocated to the Mid Cap Value Strategy normally is invested primarily in equity securities of mid cap value companies. In constructing this portion of the fund's portfolio, NIMNA uses a value approach to identify stocks whose current market prices trade at a large discount to their intrinsic value, determined by the sub-adviser's assessment of fundamentals, valuation and catalyst(s). The value style attempts to benefit from valuation inefficiencies and underappreciated fundamental prospects present in the marketplace. Items such as free cash flow, earning power, controversy assessment, growth prospects and identification of competitive advantages may be used to help assess a stock's intrinsic value. The strategy invests in stocks priced in the market at a discount to their intrinsic value which have a catalyst present to enable higher revaluation.
