Under normal circumstances, the Fund invests at least 80% of its assets in debt and other fixed-income securities rated lower than investment-grade (and their unrated equivalents) or other high-yielding debt securities. These are often called junk bonds and are speculative in nature. Most of these will be securities rated in the fifth or lower categories by a nationally recognized statistical rating organization (NRSRO). The Fund may also invest in securities having a variable or floating interest rate. 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 up to 20% of its assets in the following types of instruments: payment-in-kind or deferred-interest obligations, defaulted securities, asset-backed securities, securities rated lower than B- or its equivalent by at least two rating agencies and securities having limited liquidity. The Fund can make foreign investments, but the Fund does not expect such investments to exceed 20% of its assets under most circumstances. The Fund can also invest in U.S. Treasury and agency securities or other short-term instruments when other suitable investment opportunities are not available, or when Teachers Advisors, LLC (Advisors) would like to build the Funds liquidity. Over long periods of time, a broadly diversified portfolio of lower-rated, higher-yielding securities is designed to, net of capital losses, provide a higher net return than a similarly diversified portfolio of higher-rated, lower-yielding securities of similar duration. Advisors attempts to minimize the risks of investing in lower-rated securities by: Doing its own credit analysis (independent of the rating agencies). The Fund buys securities of issuers with a balance of operational and financial risks that Advisors believes make it likely that such issuers will be able to meet their financial obligations; Constructing a portfolio of securities diversified by industry, maturity, duration and credit quality; and Buying or selling particular securities to seek to take advantage of anticipated changes and trends in the economy and financial markets. Advisors judgment of the value of any particular security is a function of its experience with lower-rated securities, evaluation of general economic and securities market conditions and the financial condition of the securitys issuer. Under some market conditions, the Fund may sacrifice potential yield in order to adopt a defensive posture designed to preserve capital. The Fund may purchase and sell futures, options, swaps, forwards and other fixed-income derivative instruments to carry out the Funds investment strategies. The benchmark index for the Fund is the ICE BofA BB-B U.S. Cash Pay High Yield Constrained Index. Show less
