The performance quoted represents past performance and does not guarantee future results. Current performance may be lower or higher than the performance information shown. The investment return and principal value of an investment in the Portfolio will fluctuate, so that your shares, when redeemed, may be worth more or less than their original cost. See above “Average Annual Total Returns %” for performance information current to the most recent month-end. Returns for the other share classes will vary due to different charges and expenses. Performance assumes reinvestment of distributions and does not account for taxes.

Total investment return at net asset value has been calculated assuming a purchase at net asset value at the beginning of the period and a sale at net asset value at the end of the period; and assumes reinvestment of dividends, capital gain distributions and return of capital distributions/allocations, if any, in accordance with the provisions of the dividend reinvestment plan. Net asset value equals total Fund assets net of Fund expenses such as operating costs and management fees. Total investment return at net asset value is not annualized for periods less than one year.

Benchmark Disclosures

S&P 500 Index

The Standard and Poor's 500 Index is an unmanaged capitalization-weighted index of 500 stocks designed to measure performance of the broad domestic economy through changes in the aggregate market value of 500 stocks representing all major industries. The index does not reflect fees, brokerage commissions, taxes or other expenses of investing. Investors cannot invest directly in an index.

Principal Risks

You could lose money on an investment in the Portfolio. Any of the following risks, among others, could affect Portfolio performance or cause the Portfolio to lose money or to underperform market averages of other funds.

Company

The price of a given company’s stock could decline or underperform for many reasons including, among others, poor management, financial problems, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless.

Derivative Instruments

Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying securities, credit risk with respect to the counterparty, risk of loss due to changes in interest rates and liquidity risk. The use of certain derivatives may also have a leveraging effect which may increase the volatility of the Portfolio and reduce its returns.

Index Strategy

The index selected may underperform the overall market and the Portfolio might fail to track its target index. The correlation between the Portfolio and index performance may be affected by the Portfolio’s expenses and the timing of purchases and redemptions of the Portfolio’s shares. The Portfolio’s actual holdings might not match the Index and the Portfolio’s effective exposure to index securities at any given time may not equal 100%.

Liquidity

If a security is illiquid, the Portfolio might be unable to sell the security at a time when the Portfolio’s manager might wish to sell, and the security could have the effect of decreasing the overall level of the Portfolio’s liquidity. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, which could vary from the amount the Portfolio could realize upon disposition. The Portfolio may make investments that become less liquid in response to market developments or adverse investor perception. The Portfolio could lose money if it cannot sell a security at the time and price that would be most beneficial to the Portfolio.

Market

Stock prices may be volatile and are affected by the real or perceived impacts of such factors as economic conditions and political events. The stock market tends to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods.

Other Investment Companies

The main risk of investing in other investment companies, including exchange-traded funds, is the risk that the value of the securities underlying an investment company might decrease. Because the Portfolio may invest in other investment companies, you will pay a proportionate share of the expenses of that other investment company (including management fees, administration fees, and custodial fees) in addition to the expenses of the Portfolio.

Securities Lending

Securities lending involves two primary risks: “investment risk” and “borrower default risk.” Investment risk is the risk that the Portfolio will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Portfolio will lose money due to the failure of a borrower to return a borrowed security in a timely manner.

An investment in the Portfolio is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.
