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:

Expense Example	TIAA-CREF Bond Plus Fund Advisor Class USD ($)
1 year	$ 42
3 years	$ 132

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 285% of the average value of its portfolio.

Principal investment strategies

Under normal circumstances, the Fund invests at least 80% of its assets in bonds. For these purposes, bonds include fixed-income securities of all types. The Fund’s portfolio is divided into two segments. The first segment, which makes up at least 70% of the Fund’s assets, is invested primarily in a broad range of investment-grade bonds and fixed-income securities, including, but not limited to, corporate bonds, U.S. Treasury and agency securities and mortgage-backed and asset-backed securities. The securities within the Fund’s first segment are mainly high-quality instruments rated in the top four credit categories by Moody’s or S&P, or deemed to be of the same quality by Teachers Advisors, Inc. (“Advisors”) using its own credit analysis. The second segment, which will not exceed 30% of the Fund’s assets, is invested in fixed-income securities and bonds with special features in an effort to improve the Fund’s total return. Potential investments in this segment include, but are not limited to, non-investment-grade securities (those rated Ba1 or lower by Moody’s or BB+ or lower by S&P), emerging market fixed-income securities and convertible and preferred securities. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.

The Fund may invest in fixed-income securities of any duration. As of May 31, 2015, the duration of the Fund’s benchmark index, the Barclays U.S. Aggregate Bond Index, was 5.52 years.

The Fund’s investments in mortgage-backed securities can include pass-through securities sold by private, governmental and government-related organizations and collateralized mortgage obligations (“CMOs”). Mortgage pass-through securities are created when mortgages are pooled together and interests in the pool are sold to investors. The cash flow from the underlying mortgages is “passed through” to investors in periodic principal and interest payments. CMOs are obligations that are fully collateralized directly or indirectly by a pool of mortgages from which payments of principal and interest are dedicated to the payment of principal and interest on the CMO.

The Fund may use an investment strategy called “mortgage rolls” (also referred to as “dollar rolls”), in which the Fund sells securities for delivery in the current month and simultaneously contracts with a counterparty to repurchase similar (same type, coupon and maturity) but not identical securities on a specified future date. The Fund loses the right to receive principal and interest paid on the securities sold. However, the Fund would benefit to the extent of any price received for the securities sold and the lower forward price for the future purchase (often referred to as the “drop”) plus the interest earned on the short-term investment awaiting the settlement date of the forward purchase. If such benefits exceed the income and gain or loss due to mortgage repayments that would have been realized on the securities sold as part of the mortgage roll, the use of this technique will enhance the investment performance of the Fund compared with what such performance would have been without the use of mortgage rolls. Realizing benefits from the use of mortgage rolls depends upon the ability of Advisors to predict correctly mortgage prepayments and interest rates.

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 also engage in relative value trading, a strategy in which the Fund reallocates assets across different sectors and maturities. Relative value trading is designed to enhance the Fund’s returns but increases the Fund’s portfolio turnover rate.

The Fund may purchase and sell futures, options, swaps, forwards and other fixed-income derivative instruments to carry out the Fund’s investment strategies.

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.

· 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.

· 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.

· 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.

· Mortgage Roll Risk—The risk that Advisors will not correctly predict mortgage prepayments and interest rates, which will diminish the Fund’s performance.

· 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.

· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging markets countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid 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 markets countries.

· 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 classes, which would have substantially similar annual returns to the new Advisor Class because all of the Fund’s classes are invested in the same portfolio of securities with the only difference being that the classes do not have the same 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. 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, Retirement, Premier and Retail Classes 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. After-tax performance is also 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 performance in the bar chart and table has not been restated to reflect any difference between the existing classes’ expenses and estimated Advisor Class expenses. Because existing class shares generally are expected to have different expenses than Advisor Class shares, if the charts below had been restated with Advisor Class expenses, performance would have differed.

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.
