1	Estimate is for the current fiscal year.
2	“Acquired fund fees and expenses” are the Fund’s proportionate amount of the expenses of any investment companies or pools in which the Fund invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly as a result of the Fund’s investments. 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, LLC, has contractually agreed to reimburse the Fund for any Total annual Fund operating expenses (excluding interest, taxes, brokerage commissions or other transactional expenses, Acquired fund fees and expenses and extraordinary expenses) that exceed: (i) 0.25% of average daily net assets for Institutional Class shares; (ii) 0.40% of average daily net assets for Advisor Class shares; (iii) 0.40% of average daily net assets for Premier Class shares; (iv) 0.50% of average daily net assets for Retirement Class shares; and (v) 0.64% of average daily net assets for Retail Class shares of the Fund. These expense reimbursement arrangements will continue through at least February 28, 2018, 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 expense reimbursement agreement will remain in place through February 28, 2018, 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:

	Institutional Class		Advisor Class		Premier Class		Retirement Class		Retail Class
1 year	$	24	$	33	$	39	$	49	$	63
3 years	$	74	$	103	$	122	$	154	$	199

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. During the fiscal year ended October 31, 2016, the Fund’s portfolio turnover rate was 30% of the average value of its portfolio.

Principal investment strategies

Under normal circumstances, the Fund invests at least 80% of its assets in equity securities that comprise its benchmark index, the MSCI Emerging Markets^®Index (“MSCI EM Index”), or in instruments with economic characteristics similar to all or a portion of the MSCI EM Index. The MSCI EM Index is designed to measure equity market performance in the global emerging markets. The Fund buys most, but not necessarily all, of the stocks in its benchmark index, and will attempt to closely match the overall investment attributes of its benchmark index. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.

The Fund is designed to track various emerging market equity markets as a whole or a segment of these markets. The Fund primarily invests its assets in equity securities its investment adviser, Teachers Advisors, LLC (“Advisors”), has selected to track a designated stock market index.

Because the return of an index is not reduced by investment and other operating expenses, the Fund’s ability to match the returns of the MSCI EM Index is negatively affected by the costs of buying and selling securities as well as the Fund’s fees and other expenses. The use of a particular index by the Fund is not a fundamental policy and may be changed without shareholder approval. The portfolio management team of Advisors will attempt to build a portfolio that generally matches the market weighted investment characteristics of the Fund’s benchmark index.

From time to time, Advisors may determine that the Fund may not invest in securities of issuers that do not meet certain corporate governance criteria. The Fund currently does not invest in certain companies with operations in Sudan.

Principal investment risks

You could lose money over short or long periods by investing in this Fund. An investment in the Fund, due to the nature of the Fund’s portfolio holdings, typically is subject to the following principal investment risks:

·Market Risk—The risk that market prices of portfolio investments held by the Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may

TIAA-CREF Emerging Markets Equity Index Fund ■Summary Prospectus     3

affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.

·Issuer Risk (often called Financial Risk)—The risk that an issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of the issuer’s financial instruments over short or extended periods of time.

·Index Risk—The risk that the Fund’s performance may not correspond to its benchmark index for any period of time and may underperform such index or the overall financial market. Additionally, to the extent that the Fund’s investments vary from the composition of its benchmark index, the Fund’s performance could potentially vary from the index’s performance to a greater extent than if the Fund merely attempted to replicate the index.

·Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.

·Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many emerging market countries.

·Illiquid Investments Risk—The risk that illiquid investments may be difficult to sell for the value at which they are carried, if at all, or at any price within the desired time frame.

Please see the non-summary portion of the Prospectus for more detailed information about the risks described above.

Past performance

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Institutional Class of the Fund, before taxes, in each full calendar year since inception of the Institutional Class. Because the expenses vary across share classes, the performance of the Institutional Class may vary from the other share classes. Below the bar chart are the best and worst returns of the Institutional Class for a calendar quarter during the full calendar-year periods covered by the bar chart. The performance

table following the bar chart shows the Fund’s average annual total returns for the Institutional, Advisor, Premier, Retirement and Retail classes over the applicable one-year, five-year, ten-year and since-inception periods ended December 31, 2016, and how those returns compare to those of the Fund’s benchmark index. After-tax performance is shown only for Institutional Class shares, and after-tax returns for the other classes of shares will vary from the after-tax returns presented for Institutional Class shares.

The returns shown below reflect previous agreements by Advisors to waive or reimburse the Fund for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The benchmark index listed below is unmanaged, and you cannot invest directly in an index. The returns for the benchmark index reflect no deduction for fees, expenses or taxes.
