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, 2017, 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:

Expense Example - TIAA-CREF International Opportunities Fund - USD ($)	Institutional Class	Advisor Class	Premier Class	Retirement Class	Retail Class
1 year	$ 64	$ 76	$ 82	$ 91	$ 102
3 years	202	237	255	284	318
5 years	351	411	444	493	552
10 years	$ 786	$ 918	$ 990	$ 1,096	$ 1,225

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, 2015, the Fund’s portfolio turnover rate was 41% of the average value of its portfolio.

Principal investment strategies

The Fund primarily invests in equity securities of issuers in developed and emerging markets located around the world but outside the United States. The Fund anticipates investing in a number of foreign markets, but at a minimum it will invest in at least three countries outside the United States. The Fund’s investment adviser, Teachers Advisors, Inc. (“Advisors”), selects individual stocks, and lets the Fund’s country and regional asset allocations evolve from this stock selection. The Fund may invest in companies of all sizes.

Advisors typically invests in companies that it believes can demonstrate positive and sustainable structural change. In addition, Advisors looks for companies in the early stages of a structural growth opportunity driven by differentiated products and/or services that maintain strong barriers to entry, continue to outgrow peers and demonstrate accelerating top-line growth with margin expansion. Advisors will typically invest in these types of companies when Advisors believes that their stock prices do not fully reflect the stock’s potential value, based on current earnings, assets and long-term growth prospects.

The Fund is actively managed; however, Advisors regularly reviews the Fund’s sector and country exposure against the Fund’s benchmark index, the Morgan Stanley Capital International ACWI (All Country World Index) ex USA^®Index (the “MSCI ACWI ex USA^®Index”), to seek to control risk.

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 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.

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

· 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.

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, Premier, Retirement and Retail Classes over the applicable one-year, five-year, ten-year and since-inception periods ended December 31, 2015, and how those returns compare to those of the Fund’s benchmark index. The Advisor Class does not have a full year of performance and is not included in the table. 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.
