Important information on risk
Mutual fund investing involves risk; principal loss is possible. Debt or fixed income securities such as those held by the Fund, are subject to market risk, credit risk, interest rate risk, call risk, tax risk, political and economic risk, and income risk. As interest rates rise, bond prices fall. Credit risk refers to an issuers ability to make interest and principal payments when due. The Fund concentrates in non-investment-grade and unrated bonds with long maturities and durations which carry heightened credit risk, liquidity risk, and potential for default. In addition, the Fund oftentimes engages in a significant amount of portfolio leverage and in doing so, assumes a high level of risk in pursuit of its objectives. Leverage involves the risk that the Fund could lose more than its original investment and also increases the Fund's exposure to volatility, interest rate risk and credit risk.
The Nuveen Family of Funds and the TIAA-CREF Funds are distinct fund families that comprise different investment products, each with its own features, terms and conditions, fee structures and risk factors. Please note, there are no exchange privileges between the two fund families.
Returns quoted represent past performance which is no guarantee of future results. Investment returns and principal value will fluctuate so that when shares are redeemed, they may be worth more or less than their original cost. Current performance may be higher or lower than the performance shown. Total returns for a period of less than one year are cumulative. Returns without sales charges would be lower if the sales charges were included. Returns assume reinvestment of dividends and capital gains.
Performance assumes the reinvestment of dividends and capital gains. Class A shares have a 4.20% maximum sales charge. Class C shares have a 1% CDSC for redemptions within less than one year, which is not reflected in the one-year total return. Class I shares have no sales charge and may be purchased under limited circumstances or by specified classes of investors. Class R6 shares have no sales charge and are available to certain qualified retirement plans and other investors as set forth in the statement of additional information.
Some income may be subject to state and local taxes and to the federal alternative minimum tax. Capital gains, if any, are subject to tax.
The SEC 30-day yield is computed under an SEC standardized formula and is based on the maximum offer price per share. Subsidized (Sub.) yields reflect fee waivers in effect. Without such waivers, yields would be reduced. Unsubsidized (Unsub.) yields do not reflect fee waivers in effect.
Distribution rate is the most recent dividend per share (annualized) divided by the respective price per share. The distribution rate also differs from the SEC 30-day yield because the Fund may be paying out more or less than it is earning and it may not include the effect of amortization of bond premium.
Class A share star ratings do not include the effect of sales charges which would lower performance. Investment performance reflects applicable fee waivers. Without such waivers, total returns would be reduced and ratings could be lower.
The Morningstar RatingTM for funds, or "star rating", is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods. ©2023 Morningstar, Inc.
