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. The Fund attempts to achieve the return of the foreign equity markets, as represented by its benchmark index, the MSCI EAFE®(Europe, Australasia, Far East) Index (the “MSCI EAFE Index”), while taking into consideration certain ESG criteria, which include criteria relating to carbon emissions 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 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, nuclear power, thermal coal 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 emissions and (2) do not have evidence of fossil fuel reserves ownership, regardless of industry. The determination of leadership criteria takes into consideration company carbon emissions both in absolute terms (e.g., tons of carbon emitted directly into the atmosphere) and 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 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.
