    Important Risk Considerations

    The fund may not achieve its objective and/or you could lose money on your investment in the fund.

    Bond: Investments in debt instruments may decline in value as the result of, or perception of, declines in the credit quality of the issuer, borrower, counterparty, or other entity responsible for payment, underlying collateral, or changes in economic, political, issuer-specific, or other conditions. Certain types of debt instruments can be more sensitive to these factors and therefore more volatile. In addition, debt instruments entail interest rate risk (as interest rates rise, prices usually fall). Therefore, the portfolio's value may decline during rising rates. Portfolios that consist of debt instruments with longer durations are generally more sensitive to a rise in interest rates than those with shorter durations. At times, and particularly during periods of market turmoil, all or a large portion of segments of the market may not have an active trading market. As a result, it may be difficult to value these investments and it may not be possible to sell a particular investment or type of investment at any particular time or at an acceptable price. The price of an instrument trading at a negative interest rate responds to interest rate changes like other debt instruments; however, an instrument purchased at a negative interest rate is expected to produce a negative return if held to maturity.

    International: Investments in foreign markets can involve greater risk and volatility than U.S. investments because of adverse market, currency, economic, industry, political, regulatory, geopolitical, or other conditions.

    Derivatives: Investments in derivatives can be used to take both long and short positions, be highly volatile, involve leverage (which can magnify losses), and involve risks in addition to the risks of the underlying indicator(s) on which the derivative is based, such as counterparty and liquidity risk.

    High Yield: Investments in below investment grade quality debt instruments can be more volatile and have greater risk of default, or already be in default, than higher-quality debt instruments.

    Please see the prospectus for further information on these and other risk considerations.

      Distributions
      The Record Date is the date on which a fund declares a distribution. To receive the distribution, an investor must be a shareholder of record on that date.

      The Payable Date is the date on which the distribution is paid to shareholders.

      Dividend Rate per Share is the amount of dividend that a shareholder will receive for each share held. It can be calculated by taking the total amount of dividends paid and dividing it by the total shares outstanding.

      Dividend Reinvestment at NAV is the automatic reinvestment of shareholder dividends in more shares at net asset value.

      Ex-Dividend Date is the date on which a fund goes ex-dividend. The interval between the announcement and the payment of the next dividend. An investor must own the fund before the ex-dividend date to be eligible for the dividend payout.

      Long-term Capital Gain The gain on the sale of a capital asset where the holding period was more than 12 months and the profit was subject to the long-term capital gains tax. (Source: Barron's Dictionary of Finance and Investment Terms)

      Short-term Capital Gain For tax purposes the profit realized from the sale of securities or other capital assets held for less than 12 months. Short-term gains are taxable at ordinary income rates to the extent they are not reduced by offsetting capital losses. (Source: Barron's Dictionary of Finance and Investment Terms)

      The portfolio is actively managed, and current holdings may be different.

      Sector, Holding & Characterstics

      Holding Characteristics
      Average Coupon: Average Coupon is the equivalent exposure weighted coupon of all interest bearing instruments as a percent of the total equivalent exposure of all fixed income holdings, including short term and interest rate derivatives which have coupons. Coupons are netted for securities with a payable and receivable leg. Non-accruing securities are treated as having a coupon equal to zero.

      Average Effective Duration is a measure of how much a bond's price is likely to fluctuate with general changes in interest rates, e.g., if rates rise 1.00%, a bond with a 5-year duration is likely to lose about 5.00% of its value.

      Average Effective Maturity is a weighted average of maturity of the bonds held in a portfolio, taking into account any prepayments, puts, and adjustable coupons which may shorten the maturity. Longer-maturity funds are generally considered more interest-rate sensitive than shorter maturity funds.

      Weighted average yield-to-worst of all portfolio holdings excluding cash & derivatives. Yield-to-worst is the annual estimate of the portfolio yield considering factors such as call provisions, prepayments, and other features that may affect a bond's cash flow; and assumes no default. It is an estimated characteristic at a point in time and is not a measure of portfolio performance.

      Performance Statistics

      Alpha is a measure of the portfolio's risk-adjusted performance. When compared to the portfolio's beta, a positive alpha indicates better-than-expected portfolio performance and a negative indicates alpha worse-than-expected portfolio performance.

      Beta is a measure of the volatility of a portfolio relative to the overall market. A beta less than 1.0 indicates lower risk than the market; a beta greater than 1.0 indicates higher risk than the market. It is most reliable as a risk measure when the return fluctuations of the portfolio are highly correlated with the return fluctuations of the index chosen to represent the market.

      Information ratio is a measure of consistency in excess return. It is calculated by taking the annualized excess return over a benchmark and dividing it by the annualized standard deviation of excess return.

      R squared represents the percentage of the portfolio's movements that can be explained by the general movements of the market.  Index portfolios will tend to have values very close to 100.  R squared is not a measure of performance.

      The Sharpe Ratio is a risk-adjusted measure calculated to determine reward per unit of risk. It uses a standard deviation and excess return. The higher the Sharpe Ratio, the better the portfolio's historical risk-adjusted performance.

      Standard Deviation is an indicator of the portfolio's total return volatility, which is based on a minimum of 36 monthly returns. The larger the portfolio's standard deviation, the greater the portfolio's volatility.

      Tracking error is the standard deviation of a portfolio's excess returns. Excess returns are a portfolio's return minus the benchmark's annualized return.

      Treynor Ratio: Treynor Ratio is a risk adjusted measure of performance. It is the ratio of the annualized excess return of the portfolio over the risk free rate for a given period divided by the Beta of the portfolio versus its benchmark for the same period. It measures the amount of excess return over the risk free rate earned per unit of systematic risk (beta) assumed.

      Upside and downside capture is a measure of how well a manager was able to replicate or improve on phases of positive benchmark returns, and how badly the manager was affected by phases of negative benchmark returns. Upside capture ratio for a portfolio is calculated by taking the portfolio's return during periods when the benchmark had a positive return and dividing it by the benchmark return during that same period. Downside capture ratio is calculated by taking the portfolio's return during the periods of negative benchmark performance and dividing it by the benchmark return for that period.

      For all securities other than those described below, ratings are assigned utilizing ratings from Moody’s, Fitch, and Standard & Poor’s and applying the following hierarchy: If all three agencies provide a rating, the consensus rating is assigned if applicable or the middle rating if not; if two of the three agencies rate a security, the lower of the two is assigned. If none of the 3 Rating Agencies above assign a rating, but the security is rated by DBRS Morningstar, then the DBRS Morningstar rating is assigned. If none of the 4 rating agencies listed above rate the security, but the security is rated by the Kroll Bond Rating Agency (KBRA), then the KBRA rating is assigned. Other Not Rated includes other fixed income securities not rated by any rating agency. Ratings are shown in the S&P and Fitch scale (e.g., AAA). All ratings are subject to change. The portfolio itself has not been rated by any rating agency. The credit quality of a particular security or group of securities does not ensure the stability or safety of an overall portfolio. The quality ratings of individual issues/issuers are provided to indicate the credit-worthiness of such issues/ issuer and generally range from AAA, Aaa, or AAA (highest) to D, C, or D (lowest) for S&P, Moody’s, and Fitch respectively. The index rating methodology may differ.

      MORNINGSTAR RATINGS

      The fund's overall Morningstar Rating measures are based on risk-adjusted returns as of 10/31/24.

      The Morningstar Rating for funds, or "star rating", is calculated for funds 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 fund'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 fund 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.

      Morningstar rankings may vary among share classes and are based on historical total returns, which are not indicative of future results. Class A share star ratings do not include any front-end sales load and are intended for those investors who have access to such purchase terms (e.g., plan participants of a defined contribution plan). Therefore, Morningstar strongly encourages investors to contact their investment professional to determine whether they are eligible to purchase the A share without paying the front load.
