2	“Acquired Fund Fees and Expenses” are the Fund’s proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because “Acquired Fund Fees and Expenses” are included in the chart above, the Fund’s operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund’s annual report.
3	Under the Fund’s expense reimbursement arrangements, the Fund’s investment adviser, Teachers Advisors, Inc. (“Advisors”), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.49% of average daily net assets for Retail Class shares; (ii) 0.35% of average daily net assets for Retirement Class shares; (iii) 0.25% of average daily net assets for Premier Class shares; and (iv) 0.10% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least December 31, 2012, unless changed with approval of the Board of Trustees.

Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through December 31, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	Retail Class		Retirement Class		Premier Class		Institutional Class
1 Year	$	87	$	73	$	62	$	47
3 Years	$	419	$	377	$	348	$	301

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 fund operating expenses or in the example, affect the Fund’s performance. The Fund has not experienced portfolio turnover as of the date of this Prospectus because the Fund is newly operational.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). The Fund is designed for investors seeking current income with some capital appreciation through a relatively stable asset allocation strategy targeting an income-oriented and conservative risk-return profile. The Fund will generally seek to meet its investment objective by investing: (1) approximately 20% of its assets in equity Underlying Funds and (2) approximately 80% of its assets in fixed-income Underlying Funds. The Fund may deviate from these target allocations by up to 10% depending upon current market conditions and outlook.

The Underlying Fund allocation targets generally represent targets for investments in equity and fixed-income asset classes. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (which may include U.S. equity, international equity, fixed-income and short-term fixed-income) represented by various Underlying Funds. To maintain an appropriate allocation among the Underlying Funds, the portfolio managers monitor the foreign and domestic equity markets, as well as overall financial and economic conditions. The Fund might sometimes be more heavily weighted toward equities or fixed-income than otherwise targeted, if the portfolio managers believe market conditions warrant. For example, the Fund might increase its holdings in fixed-income Underlying Funds in periods when the portfolio managers believe the equity markets will decline. The market sector allocations and Underlying Fund allocations may also be changed over time by the portfolio managers, including the addition and removal of market sectors and Underlying Funds in which the Fund invests in light of the Fund’s desired level of risk and potential return at a particular time as evaluated by the portfolio managers based on a mix of qualitative and quantitative factors. The portfolio managers may also opportunistically purchase other TIAA-CREF Funds or other investment pools or investment products, based on the portfolio managers’ evaluation of the market sectors and/or Underlying Funds without prior notice to shareholders.

As a result of its investments in the Underlying Funds, the Fund’s returns will reflect investments in a mix of domestic and foreign equities of companies of

TIAA-CREF Lifestyle Income Fund ■Summary Prospectus     3

various sizes and a variety of domestic and foreign fixed-income instruments of private and governmental issuers of varying maturities and credit qualities.

As part of the Fund’s ability to invest in unaffiliated investment products or pools noted above, the Fund may invest in exchange-traded funds (“ETFs”) and exchange-traded notes (“ETNs”) to gain exposure to various market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund may use ETFs and ETNs for cash management, hedging or defensive purposes. ETFs and ETNs will be subject to the risks associated with the types of securities or sectors that they track, while ETNs, which are structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, including credit risk.

The Fund’s targetedasset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector as of December 9, 2011, are listed in the chart below. Actual allocations may differ and targeted allocations may change at any time.

Asset Class	Allocation	Market Sector	Allocation	Underlying Funds	Allocation

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund typically is subject to the following principal investment risks:

·Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.

4     Summary Prospectus■TIAA-CREF Lifestyle Income Fund

·Fund of Funds Risk—The Fund is exposed to the risks of the Underlying Funds in which it invests in direct proportion to the amount of assets the Fund allocates to each Underlying Fund. Because the Fund targets its investments in a higher percentage of fixed-income Underlying Funds, Fixed-Income Underlying Fund Risks are expected to predominate.

·Fixed-Income Underlying Funds Risks—The risks of investing in fixed-income Underlying Funds include credit risk, interest rate risk, and market volatility, liquidity and valuation risk, among others.

·Equity Underlying Funds Risks—The risks of investing in equity Underlying Funds include risks specific to their strategies, such as style risk, capitalization risk, and foreign investment risk, among others, as well as risks related to the equity markets in general.

·Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund to underperform its benchmark index or mutual funds with similar investment objectives.

·Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend in part upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.

There can be no assurances that the Fundor an Underlying Fund’s will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.
