Why invest in this Fund?

The fund seeks to match the total return of the S&P 500® Index. To pursue its goal, the fund generally is fully invested in stocks included in the S&P 500® Index and in futures whose performance is tied to the index. In addition to investing in futures, the fund may invest in exchange-traded funds (ETFs) whose performance is tied to the index. Typically, these investments may be made when the fund's available cash balances cannot otherwise be efficiently or effectively invested directly (due to, for example, size or timing considerations).

Yield fluctuates and past performance is no guarantee of future results.

The SEC 30-day Yield is calculated by dividing the net investment income per share earned during the period (calculated in accordance with regulatory guidelines) by the maximum offering price per share on the last day of the period.

Unsubsidized yield displays what the fund's 30-Day SEC Yield would have been had no fee waiver or expense reimbursement been in place during the period.

Gross Expenses is the total annual operating expense ratio for the fund, before any fee waivers or expense reimbursements. Net Expenses is the total annual operating expense ratio for the fund, after any applicable fee waivers or expense reimbursements. The Gross Expenses, or Net Expenses (if including fee waivers or expense reimbursements) is the actual fund expense ratio applicable to investors.

Stats & Risks

Main Risks

An investment in the fund is not a bank deposit. It is not insured or guaranteed by the FDIC or any other government agency. It is not a complete investment program. The fund's share price fluctuates, sometimes dramatically, which means you could lose money.

Equity funds are subject generally to market, market sector, market liquidity, issuer, and investment style risks, among other factors, to varying degrees, all of which are more fully described in the fund's prospectus.

ETFs trade like stocks, are subject to investment risk, including possible loss of principal. The risks of investing in ETFs typically reflect the risks associated with the types of instruments in which the ETF invests.

Diversification cannot assure a profit or protect against loss.

The fund uses an indexing strategy. It does not attempt to manage market volatility, use defensive strategies or reduce the effects of any long-term periods of poor stock performance.
