Fund Summary

Fund/Class:
Fidelity Freedom® Index 2050 Fund/Premier

Investment Objective

The fund seeks high total return until its target retirement date. Thereafter the fund's objective will be to seek high current income and, as a secondary objective, capital appreciation.

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)

Management fee		0.06%
Distribution and/or Service (12b-1) fees		None
Other expenses^(a)		0.00%
Total annual operating expenses		0.06%

(a) Based on estimated amounts for the current fiscal year.

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:

1 year	$6
3 years	$19
5 years	$34
10 years	$77

Portfolio Turnover

The fund will not incur transaction costs, such as commissions, when it buys and sells shares of underlying Fidelity^® funds (or "turns over" its portfolio), but it could incur transaction costs if it were to buy and sell other types of securities directly. If the fund were to buy and sell other types of securities directly, a higher portfolio turnover rate could indicate higher transaction costs and could result in higher taxes when fund shares are held in a taxable account. Such costs, if incurred, would not be reflected in annual operating expenses or in the example and would affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 77% of the average value of its portfolio.

Principal Investment Strategies

Investing primarily in a combination of Fidelity^® domestic equity funds, international equity funds, bond funds, and short-term funds (underlying Fidelity^® funds), each of which (excluding any money market fund) seeks to provide investment results that correspond to the total return of a specific index.

Allocating assets according to an asset allocation strategy shown in the glide path below that adjusts over time until it reaches an allocation similar to that of the Fidelity Freedom^® Index Income Fund, approximately 10 to 19 years after the year 2050. Fidelity Management & Research Company LLC (the Adviser) may modify the fund’s asset allocations from time to time when in the interests of shareholders.

Buying and selling futures contracts (both long and short positions) in an effort to manage cash flows efficiently, remain fully invested, or facilitate asset allocation.

The asset allocation shown in the glide path depicts the allocation to domestic equity funds, international equity funds, bond funds (including investment grade debt, inflation-protected debt, and long-term treasury debt), and short-term funds.

The Adviser, under normal market conditions, will make investments that are consistent with seeking high total return for several years beyond the fund's target retirement date in an effort to achieve the fund's overall investment objective.

Using an asset allocation among underlying Fidelity^® funds and futures as of April 1, 2020, of approximately:

	Domestic Equity Funds	54%
	International Equity Funds	36%
	Investment Grade Bond Funds	7%
	Long-Term Treasury Bond Funds	3%
	Inflation-Protected Bond Funds	0%
	Short-Term Funds	0%

* The Adviser may change these percentages over time. The allocation percentages may not add to 100% due to rounding.

Designed for investors who anticipate retiring in or within a few years of 2050 (target retirement date) at or around age 65.

Principal Investment Risks

Shareholders should consider that no target date fund is intended as a complete retirement program and there is no guarantee that any single fund will provide sufficient retirement income at or through your retirement. The fund's share price fluctuates, which means you could lose money by investing in the fund, including losses near, at or after the target retirement date.

Asset Allocation Risk. The fund is subject to risks resulting from the Adviser's asset allocation decisions. The selection of underlying funds and the allocation of the fund's assets among various asset classes could cause the fund to lose value or its results to lag relevant benchmarks or other funds with similar objectives.

Investing in Other Funds. The fund bears all risks of investment strategies employed by the underlying funds, including the risk that the underlying funds will not meet their investment objectives.

Stock Market Volatility. The Adviser will continue to invest the fund's assets in equity funds in the years following the fund's target retirement date in an effort to achieve the fund's overall investment objective. Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market, including different market sectors, and different types of securities can react differently to these developments.

Interest Rate Changes. Interest rate increases can cause the price of a debt security to decrease.

Foreign Exposure. Foreign markets, particularly emerging markets, can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile. Foreign exchange rates also can be extremely volatile.

Industry Exposure. Market conditions, interest rates, and economic, regulatory, or financial developments could significantly affect a single industry or group of related industries.

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. Changes in the financial condition of an issuer or counterparty (e.g., broker-dealer or other borrower in a securities lending transaction) can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's value or result in delays in recovering securities and/or capital from a counterparty. 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 an underlying index fund and its index may vary somewhat due to factors such as fees and expenses of the underlying fund, transaction costs, sample selection, regulatory restrictions, and timing differences associated with additions to and deletions from the index. Errors in the construction or calculation of the index may occur from time to time and may not be identified and corrected for some period of time, which may have an adverse impact on an underlying fund and its shareholders.

Passive Management Risk. Some of the underlying funds in which the fund invests are managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities, regardless of the current or projected performance of an underlying fund's index or of the actual securities included in the index. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, the performance of these underlying funds could be lower than actively managed funds that may shift their portfolio assets to take advantage of market opportunities or lessen the impact of a market decline or a decline in the value of one or more issuers.

Leverage Risk. Leverage can increase market exposure, magnify investment risks, and cause losses to be realized more quickly.

Securities Lending Risk. Securities lending involves the risk that the borrower may fail to return the securities loaned in a timely manner or at all. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, an underlying fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral.

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. 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 changes in the performance of Institutional Premium Class shares from year to year and compares the performance of Institutional Premium Class shares to the performance of a securities market index and a hypothetical composite of market indexes over various periods of time. The indexes have characteristics relevant to the fund's investment strategies. Index descriptions appear in the "Additional Index Information" section of the prospectus. Past performance (before and after taxes) is not an indication of future performance.

Year-by-Year Returns*

During the periods shown in the chart:	Returns	Quarter ended
Highest Quarter Return	11.94%	March 31, 2019
Lowest Quarter Return	(11.88)%	December 31, 2018
Year-to-Date Return	(19.14)%	March 31, 2020

Premier Class would have substantially similar annual returns to Institutional Premium Class because the classes are invested in the same portfolio of securities. Premier Class's returns would differ from Institutional Premium Class's returns only to the extent that the classes do not have the same expenses.

Average Annual Returns*

After-tax returns are calculated using the historical highest individual federal marginal income tax rates, but do not reflect the impact of state or local taxes. Actual after-tax returns may differ depending on your individual circumstances. The after-tax returns shown are not relevant if you hold your shares in a retirement account or in another tax-deferred arrangement, such as an employee benefit plan (profit sharing, 401(k), or 403(b) plan). Return After Taxes on Distributions and Sale of Fund Shares may be higher than other returns for the same period due to a tax benefit of realizing a capital loss upon the sale of fund shares.

For the periods ended December 31, 2019	Past 1 year	Life of class^(a)
Institutional Premium Class
Return Before Taxes	26.09%	8.64%
Return After Taxes on Distributions	21.81%	7.27%

(a) From June 24, 2015

* The returns shown above are for Institutional Premium Class, a class of shares of the fund that is not offered through this prospectus.
