Under the Fund’s expense reimbursement arrangements, the Fund’s investment adviser, Teachers Advisors Inc., has contractually agreed to reimburse the Fund for any Total Annual Operating Expenses (excluding interest, taxes, brokerage commissions or other transactional expenses, Acquired Fund Fees and Expenses and extraordinary expenses) that exceed 0.55% of the average daily net assets for Advisor Class shares of the Fund. These expense reimbursement arrangements will continue through at least December 3, 2016, 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 December 3, 2016, 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:

	Advisor Class
1 year	$	46
3 years	$	144

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, 2014, the Fund’s portfolio turnover rate was 105% of the average value of its portfolio.

Principal investment strategies

Under normal circumstances, the Fund invests at least 80% of its assets in large-cap equity securities of issuers included in the Fund’s benchmark index, the Russell 1000^®Growth Index, at the time of purchase, but not necessarily at index weightings. For purposes of the 80% investment policy, “large-cap” securities are securities of issuers with a capitalization equal to or greater than the top 80% of issuers by capitalization within the Russell 1000^®Index at the time of purchase. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.

The Fund follows an enhanced index management strategy. The Fund’s investment adviser, Teachers Advisors, Inc. (“Advisors”), actively uses quantitative analysis to attempt to enhance the Fund’s performance relative to the Russell 1000^®Growth Index, while retaining a similar risk profile, instead of passively holding a representative basket of securities designed to match the index. The Russell 1000^®Growth Index is a subset of the Russell 1000^®Index, which represents the performance of the large-cap growth segment of the U.S. equity universe. It includes those Russell 1000^®Index companies with higher price-to-book ratios and higher forecasted growth values.

Enhanced index strategies employ quantitative modeling techniques for both stock selection and portfolio construction. With enhanced indexing, the Fund may use several different investment techniques to seek to build a portfolio of stocks that is structured to resemble and share the risk characteristics of the Fund’s benchmark index, while also seeking to outperform the benchmark index. Enhanced indexing is designed so that the Fund diverges from its benchmark index more than a pure indexing strategy, with the goal of outperforming its benchmark index while effectively managing benchmark relative risks.

Under these quantitative modeling techniques, a number of variables related to individual stocks are evaluated to select a broadly diversified group of stocks that may have the potential to provide a higher total return than that of the benchmark index, the Russell 1000^®Growth Index. The Fund uses a proprietary, quantitative stock scoring model to evaluate and score a broad universe of stocks in which the Fund invests.

Advisors will generally attempt to overweight securities (relative to the benchmark) that score high in the stock selection screening process and to either not hold or underweight securities that score low in the screening process. The Fund may also purchase foreign securities and securities issued in connection with reorganizations or other special situations. The Fund may also purchase and sell swaps and other equity derivatives to carry out the Fund’s investment strategies. The Fund’s strategy is based upon Advisors’ understanding of the interplay of market factors and does not assure successful investment. The markets or the process of selecting individual securities may be affected by factors not taken into account in Advisors’ analysis.

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.

·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.

·Style Risk—The risk that use of a particular investing style (such as growth or valueinvesting) may fall out of favor in the marketplace for various periods of time and result in underperformance relative to the broader market sector or significant declines in the value of the Fund’s portfolio investments.

·Risks of Growth Investing—Due to their relatively high valuations, growth stocks are typically more volatile than value stocks and may experience a larger decline on a forecast of lower earnings, or a negative event or market development, than would a value stock.

·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.

·Enhanced Index Risk—As an enhanced index fund, the Fund may also underperform its benchmark index due to differences between the investments of the Fund and its benchmark index.

·Quantitative Analysis Risk—The risk that stocks selected using quantitative modeling and analysis could perform differently from the market as a whole.

·Special Situation Risk—Stocks of companies involved in reorganizations, mergers and other special situations can involve the risk that such situations may not materialize or may develop in unexpected ways. Consequently, those stocks can involve more risk than ordinary securities.

·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.

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. Because the Fund only recently began offering Advisor Class shares, the performance information shown is for the Fund’s existing Institutional Class, which would have substantially similar annual returns to the new Advisor Class because the Fund’s classes are invested in the same portfolio of securities with the only difference being that the Institutional Class has lower expenses. 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. 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 Class over the applicable one-year, five-year, ten-year and since-inception periods ended December 31, 2014, and how those returns compare to those of the Fund’s benchmark index. The performance in the bar chart and table has not been restated to reflect any difference between Institutional Class expenses and estimated Advisor Class expenses. Because Institutional Class shares are expected to have lower expenses than Advisor Class shares, if the charts below had been restated with Advisor Class expenses, performance would have been lower.

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.

Tax information

The Fund intends to make distributions to shareholders that may be taxed as ordinary income or capital gains.

Payments to broker-dealers and other financial intermediary compensation

The Fund’s related companies may also pay the financial intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other financial intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
