#### 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:

|:---|:---|:---|:---|:---|:---|
|  | **Class A** | **Class I** | **Premier <br>Class** | **Class R6** | **Retirement <br>Class** |
| 1 year | $631 | $25 | $37 | $20 | $46 |
| 3 years | $760 | $88 | $127 | $75 | $155 |
| 5 years | $919 | $177 | $244 | $155 | $294 |
| 10 years | $1380 | $438 | $587 | $388 | $697 |

---

#### Portfolio turnover
The Fund pays transaction costs, such as commissions, as applicable, 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, 2025, the Fund's portfolio turnover rate was 21% 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 of foreign issuers that meet the Fund's ESG criteria. For these purposes, "equity securities" include equity securities of any type, including common stocks; preferred securities; warrants to purchase common stocks and preferred securities; convertible debt securities that are either in the money or immediately convertible into common stocks or preferred securities; common and preferred securities issued by master limited partnerships and real estate investment trusts; depositary receipts; and other securities with equity characteristics. The Fund attempts to achieve the return of the foreign equity markets, as represented by its benchmark index, the MSCI EAFE<sup>®</sup> (Europe, Australasia, Far East) Index (the "MSCI EAFE Index"), while taking into consideration certain ESG criteria, which include criteria relating to carbon intensity and fossil fuel reserves. See "Additional information about the Fund's benchmark index" in the non-summary portion of the Prospectus for more information about the Fund's benchmark. Fund holdings may be denominated in U.S. dollars or non-U.S. dollar currencies. For purposes of the 80% investment

Nuveen International Responsible Equity Fund ■ **Summary Prospectus** &nbsp;&nbsp;&nbsp;&nbsp;3

------

policy, the term "assets" means net assets, plus the amount of any borrowings for investment purposes.

When selecting investments for the Fund, Teachers Advisors, LLC ("Advisors"), the Fund's investment adviser, considers certain ESG criteria. The ESG criteria are generally implemented based on data provided by independent research vendor(s). The evaluation process favors companies with leadership in ESG performance relative to their peers. Typically, environmental assessment categories include climate change, natural resource use, waste management and environmental opportunities. Social evaluation categories include human capital, product safety and social opportunities. Governance assessment categories include corporate governance, business ethics and government and public policy. How well companies adhere to international norms and principles and involvement in major ESG controversies (examples of which may relate to the environment, customers, human rights and community, labor rights and supply chain, and governance) are other considerations.

The ESG evaluation process is conducted on an industry-specific basis and involves the identification of key performance indicators, which are given more or less relative weight compared to the broader range of potential assessment categories. When ESG concerns exist, the evaluation process gives careful consideration to how companies address the risks and opportunities they face in the context of their sector or industry and relative to their peers. The Fund will not generally invest in companies significantly involved in certain business activities, including but not limited to the production of alcohol, tobacco, military weapons, firearms, thermal coal, adult entertainment, arctic oil and gas, oil sands extraction, for-profit prisons and gambling products and services.

In addition to the overall ESG performance evaluation, the Fund favors companies that (1) demonstrate leadership in managing and mitigating their current carbon intensity and (2) do not have evidence of fossil fuel reserves ownership, regardless of industry. The determination of leadership criteria takes into consideration company carbon intensity in relative terms (e.g., tons of carbon emitted per unit of economic output such as sales). Reserves are fossil fuel deposits that have not yet been extracted. Evidence of fossil fuel reserves ownership includes company disclosure and statements regarding ownership.

After the ESG evaluation process is conducted, Advisors then uses quantitative investment techniques to attempt to closely match, to the extent practicable, the overall risk characteristics of the benchmark index. Under these quantitative investment techniques, the Fund uses a risk model to evaluate the stocks in which the Fund may invest and to inform the construction of a broadly diversified group of stocks.

While Advisors generally invests in companies that meet the ESG criteria, it is not required to invest in every company that meets these criteria. In addition, concerns with respect to one ESG assessment category may not automatically eliminate an issuer from being considered an eligible Fund investment. The ESG

4&nbsp;&nbsp;&nbsp;&nbsp; **Summary Prospectus** ■ Nuveen International Responsible Equity Fund

------

criteria the Fund takes into consideration are non-fundamental investment policies and may be changed without the approval of the Fund's shareholders.

The Board of Trustees of the Trust or a designated committee thereof ("Board of Trustees") reviews the ESG criteria used to evaluate securities held by the Fund and the ESG vendor(s) that provide the data that help inform these criteria. Subject to Board review, Advisors has the right to change the ESG vendor(s) at any time and to add to the number of vendors providing the ESG data.

Investing on the basis of ESG criteria is qualitative and subjective by nature. There can be no assurance that every Fund investment will meet ESG criteria, or will do so at all times, or that the ESG criteria or any judgment exercised by Advisors will reflect the beliefs or values of any particular investor.

#### 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:

&nbsp;&nbsp;&nbsp;&nbsp;· **ESG Risk**—The risk that because the Fund's ESG criteria exclude securities of certain issuers for nonfinancial reasons, the Fund may forgo some market opportunities available to funds that do not use these criteria.

&nbsp;&nbsp;&nbsp;&nbsp;· **Low-Carbon Risk**—The risk that because the Fund's investment strategy includes a special emphasis on companies with low current carbon intensity and an absence of fossil fuel reserves ownership, the Fund's portfolio might exclude certain issuers for nonfinancial reasons and the Fund may forgo some market opportunities that otherwise would be available.

&nbsp;&nbsp;&nbsp;&nbsp;· **Market Risk**—The risk that market prices of portfolio investments held by the Fund may fluctuate rapidly or unpredictably due to a variety of factors, including responses to government actions or interventions, or 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. Such conditions may add significantly to the risk of volatility in the net asset value ("NAV") of the Fund's shares and adversely affect the Fund and its investments. From time to time, the Fund may invest a significant portion of its assets in companies in one or more related sectors or industries, which would make the Fund more vulnerable to adverse developments affecting such sectors or industries. The Fund currently invests a significant portion of its assets in companies in the financials and industrials sectors, although this may change over time.

&nbsp;&nbsp;&nbsp;&nbsp;· **Issuer Risk** (often called **Financial Risk**)—The risk that an issuer's earnings prospects, credit rating 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.

&nbsp;&nbsp;&nbsp;&nbsp;· **Foreign Investment Risk**—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory,

Nuveen International Responsible Equity Fund ■ **Summary Prospectus** &nbsp;&nbsp;&nbsp;&nbsp;5

------

currency, market or economic developments as well as armed conflicts 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 have lower 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. The Fund currently invests a significant portion of its assets in companies located in Japan, although this may change over time. Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, less public information, less stringent investor protections and less stringent accounting, corporate governance, financial reporting and disclosure standards. Changes in the value of foreign currencies may make the return on an investment increase or decrease, unrelated to the quality or performance of the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other restrictions by the United States or other governments may also negatively impact the Fund's investments. Economic sanctions and other similar governmental actions or developments could, among other things, effectively restrict or eliminate the Fund's ability to purchase or sell certain foreign securities or groups of foreign securities, and/or thus may make the Fund's investments in such securities less liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other measures that may be imposed could vary broadly in scope, and their impact is impossible to predict.

&nbsp;&nbsp;&nbsp;&nbsp;· **Large-Cap Risk**—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.

&nbsp;&nbsp;&nbsp;&nbsp;· **Mid-Cap Risk**—The risk that the stocks of mid-capitalization companies often experience greater price volatility, lower trading volume and lower overall liquidity than the stocks of larger, more established companies.

&nbsp;&nbsp;&nbsp;&nbsp;· **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 and/or strategies and may not produce the desired results or expected returns.

&nbsp;&nbsp;&nbsp;&nbsp;· **Benchmark 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.

6&nbsp;&nbsp;&nbsp;&nbsp; **Summary Prospectus** ■ Nuveen International Responsible Equity Fund

------

&nbsp;&nbsp;&nbsp;&nbsp;· **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.

&nbsp;&nbsp;&nbsp;&nbsp;· **Quantitative Analysis Risk**—The risk that stocks selected using quantitative modeling and analysis could perform differently from the market as a whole and the risk that such quantitative analysis and modeling may not adequately take into account certain factors, may contain design flaws or inaccurate assumptions and may rely on inaccurate data inputs, which may result in losses to the Fund.

&nbsp;&nbsp;&nbsp;&nbsp;· **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. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates and the imposition of currency controls or other political, economic and tax developments in the U.S. or abroad.

*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 Class R6 of the Fund, before taxes, in each full calendar year for the last ten years. Because the expenses vary across share classes, the performance of Class R6 may vary from the other share classes. Below the bar chart are the best and worst returns of Class R6 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 Class R6, Class I, Premier Class, Retirement Class and Class A over the applicable one-year, five-year, ten-year and since-inception periods ended December 31, 2025, and how those returns compare to those of the Fund's broad-based securities market and benchmark index. After-tax performance is shown only for Class R6 shares, and after-tax returns for the other classes of shares will vary from the after-tax returns presented for Class R6 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 broad-based securities market and benchmark index listed below is unmanaged, and you cannot invest directly in an index. The returns for the broad-based securities market and benchmark index reflect no deduction for fees, expenses or taxes.
