2Summary Prospectus■TIAA-CREF International Bond Fund

and Other expenses (excluding interest, taxes, brokerage commissions or other transactional expenses, Acquired fund fees and expenses, Trustee expenses and extraordinary expenses) in their entirety. Teachers Advisors, LLC expects these waiver and/or reimbursement arrangements to remain in effect indefinitely, unless changed or terminated 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 fee waivers and/or expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in the table above. 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		Class W
1 year	$	61	$	72	$	77	$	86	$	97	$	0
3 years	$	192	$	224	$	250	$	268	$	418	$	0
5 years	$	335	$	390	$	439	$	466	$	762	$	0
10 years	$	750	$	871	$	985	$	1,037	$	1,733	$	0

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, 2021, the Fund’s portfolio turnover rate was 37% of the average value of its portfolio.

Principal investment strategies

Under normal market conditions, the Fund invests at least 80% of its assets in fixed-income investments of foreign issuers and derivative instruments, including those used to manage currency risk. The Fund primarily invests in a broad range of investment-grade sovereign, quasi-sovereign and corporate fixed-income investments. The Fund may also invest in other fixed-income securities, including those of non-investment-grade quality. The Fund does not rely exclusively on rating agencies when making investment decisions. Instead, the Fund’s investment adviser, Teachers Advisors, LLC (“Advisors”), performs its own credit analysis, paying particular attention to economic trends and other market events. Country and individual issuer allocations are then overweighted or underweighted relative to the Fund’s benchmark index, the Bloomberg Global Aggregate ex-USD Index (Hedged) (the “Index”), when Advisors believes that the

TIAA-CREF International Bond Fund ■Summary Prospectus 3

Fund can take advantage of what appear to be undervalued, overlooked or misunderstood issuers that offer the potential to boost returns above that of the Index. Fund holdings may be denominated in U.S. dollars or non-U.S. dollar currencies, including emerging market currencies. Under normal market conditions, the Fund will seek to hedge to the U.S. dollar approximately 80% of the Fund’s total exposure to investments denominated in currencies other than the U.S. dollar (on a net assets basis). Such hedging is intended to manage the currency risk associated with investment in bonds denominated in currencies other than the U.S. dollar. The Fund may invest in fixed-income securities of any maturity or duration. As of December 31, 2021, the duration of the Index was 8.08 years. “Duration” is a measure of volatility in the price of a bond in response to a change in prevailing interest rates, with a longer duration indicating more volatility. The Fund considers investments of foreign issuers to generally include one or more of the following: (1) companies whose securities are principally traded outside of the United States, (2) companies having their principal business operations outside of the United States, (3) companies organized outside of the United States, and (4) foreign governments and agencies or instrumentalities of foreign governments. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes. Derivative instruments, including those used to manage currency risk, are included as assets of the Fund for the purposes of the Fund’s 80% policy.

The Fund may also engage in relative value trading, a strategy in which the Fund reallocates assets across different countries, currencies, sectors and maturities. While this strategy is designed to enhance the Fund’s returns, it may also increase the Fund’s portfolio turnover rate. In addition, an increase in interest rates as well as other factors contributing to market volatility could lead to increased portfolio turnover.

The Fund may purchase and sell futures, options, swaps and other fixed-income derivative instruments to carry out the Fund’s investment strategies. In particular, the Fund may utilize forward currency contracts and currency-related futures contracts and swap agreements to manage currency risk.

The Fund may also seek exposure to Regulation S fixed-income securities through investment in a Cayman Islands exempted company that is wholly owned and controlled by the Fund (the “Subsidiary”). Regulation S securities are securities of U.S. and non-U.S. issuers that are issued through private placement offerings without registration with the SEC pursuant to Regulation S under the Securities Act of 1933. The Subsidiary is advised by Advisors and has the same investment objective as the Fund. The Subsidiary may invest without limitation in Regulation S securities.

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 Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for the Fund to properly value its investments and that the Fund may not be able to purchase or sell an investment at an attractive price, if at all.

·Fixed-Income Foreign Investment Risk—Investment in fixed-income securities or financial instruments of foreign issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic developments. These developments may impact the ability of a foreign debt issuer to make timely and ultimate payments on its debt obligations to the Fund or impair the Fund’s ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging or developing markets. Foreign investments may also have lower overall liquidity and be more difficult to value than investments in U.S. issuers. To the extent the Fund invests a significant portion of its assets in the securities of companies in a single country or region, it may be more susceptible to adverse economic, market, political or regulatory events or conditions affecting that country or region. Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, less public information and less stringent investor protections and disclosure standards.

·Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets or otherwise economically tied to emerging market countries. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, which would affect the Fund’s ability to evaluate potential portfolio companies. As a result, there could be less information available about issuers in emerging market countries, which could negatively affect Advisors’ ability to evaluate local companies or their potential impact on the Fund’s performance. 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 have lower overall liquidity 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. Moreover, legal remedies for investors in emerging markets may be more limited, and U.S. authorities may have less ability to bring actions against bad actors in emerging market countries. Frontier markets are those emerging markets that are considered to be among the smallest, least

TIAA-CREF International Bond Fund ■Summary Prospectus 5

mature and least liquid, and as a result, the risks of investing in emerging markets are magnified in frontier markets.

·Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments and during periods when prevailing interest rates are low or negative. As of the date of this Prospectus, interest rates in the United States and in certain foreign markets are at low levels, which may increase the Fund’s exposure to risks associated with rising interest rates. In general, changing interest rates could have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.

·Credit Risk (a type of Issuer Risk)—The risk that the issuer of fixed-income investments may not be able or willing, or may be perceived (whether by market participants, rating agencies, pricing services or otherwise) as not able or willing, to meet interest or principal payments when the payments become due.

·Currency Risk—The risk that foreign (non-U.S.) currencies may decline in value relative to the U.S. dollar and adversely affect the value of the Fund’s investments in foreign currencies, securities denominated in foreign currencies or derivative instruments that provide exposure to foreign currencies.

·Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. The Fund may use futures, options, single name or index credit default swaps, or forwards, and the Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

·Currency Management Strategies Risk—Currency management strategies, including the use of forward currency contracts and other derivatives, may substantially change the Fund’s exposure to currencies and currency exchange rates and could result in losses to the Fund if currencies do not perform as Advisors anticipates. The Fund’s ability to use derivative instruments to manage currency exposure may also be altered or constrained by pending SEC regulations, if such regulations are adopted as proposed.

·Counterparty and Third Party Risk—Transactions involving a counterparty to a derivative or other instrument, or to a third party responsible for servicing the instrument, are subject to the credit risk of the counterparty or third party, and to the counterparty’s or third party’s ability to perform in accordance with the terms of the transaction.

·Sovereign Debt Risk—The risk that the issuer of non-U.S. sovereign debt or the governmental authorities that control the repayment of such debt may be unable or unwilling to repay principal or interest when due. This may result

6Summary Prospectus■TIAA-CREF International Bond Fund

from political or social factors, the general economic environment of a country, levels of foreign debt or foreign currency exchange rates, among other possible reasons. To the extent the issuer or controlling governmental authority is unable or unwilling to repay principal or interest when due, the Fund may have limited recourse to compel payment in the event of default.

·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.

·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.

·Downgrade Risk—The risk that securities are subsequently downgraded should Advisors and/or rating agencies believe the issuer’s business outlook or creditworthiness has deteriorated.

·Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments may decline in certain interest rate environments.

·Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in the Fund’s income.

·Regulation S Securities Risk—The risk that Regulation S securities may be less liquid than publicly traded securities. Regulation S securities may not be subject to the disclosure and other investor protection requirements that would be applicable to publicly traded securities. As a result, Regulation S securities may involve a high degree of business and financial risk and may result in losses.

·Risks of Investment in the Fund’s Wholly Owned Subsidiary—The Subsidiary is not registered under the Investment Company Act of 1940 (the “1940 Act”) and is not subject to its investor protections (except as otherwise noted in the Prospectus). As an investor in the Subsidiary, the Fund does not have all of the protections offered to investors by the 1940 Act. However, the Subsidiary is wholly owned and controlled by the Fund and managed by Advisors. Therefore, the Fund’s ownership and control of the Subsidiary make it unlikely that the Subsidiary would take actions contrary to the interests of the Fund or its shareholders.

·Non-Investment-Grade Securities Risk—Issuers of non-investment-grade securities, which are usually called “high-yield” or “junk bonds,” are typically in weaker financial health and such securities can be harder to value and sell and their prices can be more volatile than more highly rated securities. While these securities generally have higher rates of interest, they also involve greater risk of default than do securities of a higher-quality rating.

TIAA-CREF International Bond Fund ■Summary Prospectus 7

·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.

·Portfolio Turnover Risk—Depending on market and other conditions, the Fund may experience high portfolio turnover, which may result in greater transactional expenses, such as brokerage commissions, bid-ask spreads, or dealer mark-ups, and capital gains (which could increase taxes and, consequently, reduce returns).

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, Retail and Class W classes over the applicable one-year, five-year, ten-year and since-inception periods ended December 31, 2021, 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.
