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 July 31, 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:

Expense Example - TIAA-CREF Short-Term Bond Fund - USD ($)	Retail Class	Retirement Class	Premier Class	Institutional Class
1 Year	$ 59	$ 53	$ 43	$ 28
3 Years	186	167	135	87
5 Years	324	291	235	152
10 Years	$ 726	$ 653	$ 530	$ 343

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 March 31, 2015, the Fund’s portfolio turnover rate was 114% of the average value of its portfolio.

Principal investment strategies

Under normal circumstances, the Fund invests at least 80% of its assets in U.S. Treasury and agency securities and investment-grade fixed-income investments with an average maturity or average lives of less than 5 years. The Fund primarily invests in a broad range of investment-grade bonds and fixed-income securities, including, but not limited to, U.S. Government securities, corporate bonds and mortgage-backed and other asset-backed securities. The Fund may also invest in other fixed-income securities, including those of non-investment grade quality. The Fund may overweight or underweight individual securities or sectors as compared to their weight in the index when the Fund’s Investment Adviser, Teacher’s Advisors, Inc. (“Advisors”) finds undervalued or overlooked issues that it believes offer the potential for superior returns. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.

As of May 31, 2015, the duration of the Barclays U.S. 1–3 Year Government/Credit Bond Index was 1.91 years. Although the Fund may invest in fixed-income securities of any maturity, the duration of the Fund’s portfolio typically ranges between one and three years. The Fund also has a policy of maintaining a dollar weighted average maturity of portfolio holdings of no more than three years.

The Fund can make foreign investments, including investments in emerging market countries and non-dollar denominated instruments, but the Fund does not expect such investments to exceed 20% of its assets under most circumstances.

The Fund may purchase and sell futures, options, swaps, forwards and other fixed-income derivative instruments to carry out the Fund’s investment strategies. In particular, the Fund may purchase and sell interest rate futures to attempt to manage duration and/or certain risks.

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:

· 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 or near historic lows, 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.

· 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.

· Credit Risk (a type of Issuer Risk)—The risk that the issuer of fixed-income investments may not be able or willing to meet interest or principal payments when the payments become due.

· 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.

· 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 be less liquid and more difficult to value than investments in U.S. issuers.

· 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.

· 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.

· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing the Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.

· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing the Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.

· 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.

· 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.

· Illiquid Investments Risk—The risk that illiquid investments may be difficult to sell for their fair market value, if at all, or at any price.

· 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. 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 period covered by the bar chart. The performance table following the bar chart shows the Fund’s average annual total returns for the Institutional Class, Retirement Class, Premier Class and Retail Class over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2014, 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 the benchmark index. The returns for the benchmark index reflect no deduction for fees, expenses or taxes.
