Nuveen High Yield Fund Retirement Class TIHRX Strategy

The investment seeks total return primarily through high current income and, when consistent with its primary objective, capital appreciation. The fund invests primarily in lower-rated, higher-yielding fixed-income securities, such as domestic and foreign corporate bonds, debentures, senior loans, loan participations and assignments and notes, as well as convertible and preferred securities. Under normal circumstances, it 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.
