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, derivatives risk, and income risk. As interest rates rise, bond prices fall. Below investment grade or high yield debt securities are subject to liquidity risk and heightened credit risk. Foreign investments involve additional risks, including currency fluctuation, political and economic instability, lack of liquidity and differing legal and accounting standards. The Fund gains additional exposure to currency rates, and therefore to the risk of currency fluctuation, through investment in foreign currency contracts. The risks of foreign investments are magnified in emerging markets. Asset-backed and mortgage-backed securities are subject to additional risks such as prepayment risk, liquidity risk, default risk or adverse economic developments affecting the underlying mortgage, loan or asset. The use of dollar rolls can increase the volatility of the Fund’s share price, and it may have an adverse impact on performance unless the investment team correctly predicts mortgage prepayments and interest rates.
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 4.25% 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 R3 shares have no sales charge and are available only to certain retirement plan clients. Effective 04 Jun 2021, Class R3 will be automatically converted to Class A shares. Please see the Fund’s prospectus for more information. 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.
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.
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.
The Morningstar Medalist RatingTM is the summary expression of Morningstar’s forward-looking analysis of investment strategies as offered via specific vehicles using a rating scale of Gold, Silver, Bronze, Neutral, and Negative. The Medalist Ratings indicate which investments Morningstar believes are likely to outperform a relevant index or peer group average on a risk-adjusted basis over time. Investment products are evaluated on three key pillars (People, Parent, and Process) which, when coupled with a fee assessment, forms the basis for Morningstar’s conviction in those products’ investment merits and determines the Medalist Rating they’re assigned. Pillar ratings take the form of Low, Below Average, Average, Above Average, and High. Pillars may be evaluated via an analyst’s qualitative assessment (either directly to a vehicle the analyst covers or indirectly when the pillar ratings of a covered vehicle are mapped to a related uncovered vehicle) or using algorithmic techniques. Vehicles are sorted by their expected performance into rating groups defined by their Morningstar Category and their active or passive status. When analysts directly cover a vehicle, they assign the three pillar ratings based on their qualitative assessment, subject to the oversight of the Analyst Rating Committee, and monitor and reevaluate them at least every 14 months. When the vehicles are covered either indirectly by analysts or by algorithm, the ratings are assigned monthly. For more detailed information about these ratings, including their methodology, please go to global.morningstar.com/managerdisclosures/.
The Morningstar Medalist Ratings are not statements of fact, nor are they credit or risk ratings. The Morningstar Medalist Rating (i) should not be used as the sole basis in evaluating an investment product, (ii) involves unknown risks and uncertainties which may cause expectations not to occur or to differ significantly from what was expected, (iii) are not guaranteed to be based on complete or accurate assumptions or models when determined algorithmically, (iv) involve the risk that the return target will not be met due to such things as unforeseen changes in management, technology, economic development, interest rate development, operating and/or material costs, competitive pressure, supervisory law, exchange rate, tax rates, exchange rate changes, and/or changes in political and social conditions, and (v) should not be considered an offer or solicitation to buy or sell the investment product. A change in the fundamental factors underlying the Morningstar Medalist Rating can mean that the rating is subsequently no longer accurate.
The Morningstar Medalist Rating for funds is the summary expression of Morningstar’s forward-looking analysis of investment strategies as offered via the specific vehicles, which can include but are not limited to open-end funds, closed-end funds, exchange-traded funds, and separately managed accounts domiciled throughout the world. The Medalist Rating does not express a view on a given asset class or peer group; rather, it seeks to evaluate each strategy and associated vehicle within the context of an appropriate benchmark and peer group.
Morningstar assigns Morningstar Medalist Ratings at the vehicle level to accurately capture the impact of fee differences on expected net-of-fee alpha between different types of vehicles, including different share classes of the same fund. Morningstar’s research and academic studies have repeatedly shown that a vehicle’s ability to outperform erodes as fees become higher.
Morningstar expresses the Morningstar Medalist Rating on a five-tier scale running from Gold to Negative. For actively managed funds, Morningstar assigns Gold, Silver, and Bronze ratings to vehicles expected to add value, or “positive alpha,” over the long term when compared with a relevant Morningstar Category index after accounting for fees and risk. For passive strategies, Morningstar assigns Gold, Silver, and Bronze ratings to vehicles expected to deliver alpha that exceeds the lesser of the category median net alpha, or zero, over the long term. (Morningstar defines “long term” as periods lasting at least five years.)
