Fund Summary

Fund/Class:
Spartan^® Inflation-Protected Bond Index Fund/Investor, Fidelity Advantage^®

Investment Objective

The fund seeks to provide investment results that correspond to the total return of the inflation-protected sector of the United States Treasury market.

Fee Table

The following table describes the fees and expenses that may be incurred when you buy and hold shares of the fund.

Shareholder fees
(fees paid directly from your investment) None

Annual operating expenses
(expenses that you pay each year as a % of the value of your investment)

	Investor Class	Fidelity Advantage® Class
Management fee	0.05%	0.05%
Distribution and/or Service (12b-1) fees	None	None
Other expenses	0.15%	0.05%
Total annual operating expenses	0.20%	0.10%

This example helps compare the cost of investing in the fund with the cost of investing in other funds.

Let's say, hypothetically, that the annual return for shares of the fund is 5% and that your shareholder fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. For every $10,000 you invested, here's how much you would pay in total expenses if you sell all of your shares at the end of each time period indicated:

	Investor Class	Fidelity Advantage Class
1 year	$ 20	$ 10
3 years	$ 64	$ 32
5 years	$ 113	$ 56
10 years	$ 255	$ 128

Summary Prospectus

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 39% of the average value of its portfolio.

Principal Investment Strategies

• Normally investing at least 80% of assets in inflation-protected debt securities included in the Barclays^® U.S. Treasury Inflation-Protected Securities (TIPS) Index (Series-L).
• Engaging in transactions that have a leveraging effect on the fund, including investments in derivatives - such as swaps (interest rate, total return, and credit default) and futures contracts - and forward-settling securities, to adjust the fund's risk exposure.

Principal Investment Risks

• Interest Rate Changes. Interest rate increases can cause the price of a debt security to decrease.
• Prepayment. The ability of an issuer of a debt security to repay principal prior to a security's maturity can cause greater price volatility if interest rates change.
• Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole. A decline in the credit quality of an issuer or a provider of credit support or a maturity-shortening structure for a security can cause the price of a security to decrease.
• Correlation to Index. The performance of the fund and its index may vary somewhat due to factors such as transaction costs, sample selection, and timing differences associated with additions to and deletions from its index.
• Leverage Risk. Leverage can increase market exposure, magnify investment risks, and cause losses to be realized more quickly.
• Investing for Inflation Protection. Increases in real interest rates can cause the price of inflation-protected debt securities to decrease. Interest payments on inflation-protected debt securities can be unpredictable.

An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Unlike individual debt securities, which typically pay principal at maturity, the value of an investment in the fund will fluctuate. You could lose money by investing in the fund.

Performance

The following information is intended to help you understand the risks of investing in the fund. The information illustrates the performance of the fund's shares over the past year and compares the performance of the fund's shares to the performance of a securities market index over various periods of time. The index description appears in the Additional Index Information section of the prospectus. Past performance (before and after taxes) is not an indication of future performance.
