Source: Barron’s, “Barron’s Top Fund Families of 2019,” February 14, 2020. Barron’s rankings are based on asset weighted returns in funds in five categories: U.S. equity, world equity (including international and global portfolios), mixed asset (which invest in stocks, bonds and other securities), taxable bond, and tax-exempt (each a "Barron's ranking category"). Rankings also take into account an individual fund's performance within its Lipper peer universe. Lipper calculated each fund's net total return for the year ended December 31, 2019, minus the effects of 12b-1 fees and sales charges. Each fund in the survey was given a percentile ranking with 100 the highest and 1 the lowest in its category. That ranking measured how a fund compared with its peer "universe," as tracked by Lipper, not just the funds in the survey. Individual fund scores were then multiplied by the 2019 weighting of their Barron's ranking category as determined by the entire Lipper universe of funds. Those fund scores were then totaled, creating an overall score and ranking for each fund family in the survey in each Barron's ranking category. The process is repeated for the five- and ten-year rankings as well. Barron's Fund Family Rankings are awarded annually.

Dividend Yield is a financial ratio that shows how much a mutual fund pays out in dividends each year relative to value with maximum sales charges and without sales charges. The dividend yield is calculated by annualizing the last dividend and dividing it by the fund’s net asset value with maximum sales charges and without sales charges.

The 30-Day Standardized Yield represents net investment income earned by a fund over a 30-day period. It is expressed as an annual percentage rate using a method of calculation adopted by the Securities and Exchange Commission (SEC). Yields for other share classes will vary.

IMPORTANT INFORMATION

A Note about Risk: The Fund is subject to the general risks associated with investing in debt securities, including market, credit, liquidity, and interest rate risk. The value of investments in debt securities will fluctuate in response to market movements. When interest rates rise, the prices of debt securities are likely to decline, and when interest rates fall, the prices of debt securities tend to rise. The Fund may invest substantially in high yield, lower-rated securities. These securities carry increased risks of price volatility, illiquidity, and the possibility of default in the timely payment of interest and principal. Moreover, the specific collateral used to secure a loan may decline in value or become illiquid, which would adversely affect the loan's value. The Fund may invest in foreign or emerging market securities, which may be adversely affected by economic, political, or regulatory factors and subject to currency volatility and greater liquidity risk. The Fund may invest in derivatives, which are subject to greater liquidity, leverage, and counterparty risk. Certain of the Fund's derivative transactions may give rise to leverage risk. Leverage, including borrowing for investment purposes, may increase volatility in the Fund by magnifying the effect of changes in the value of the Fund's holdings. The use of leverage may cause investors in the Fund to lose more money in adverse environments than would have been the case in the absence of leverage. These factors may affect Fund performance.

Performance data quoted is historical. Past performance is not indicative of future results. Current performance may be higher or lower than the performance quoted. The investment return and principal value of an investment in the Fund will fluctuate so that shares, on any given day or when redeemed, may be worth more or less than their original cost.

Class A  Except as noted below, returns with sales charges reflect a maximum sales charge of 5.75% for equity funds, 2.25% for all tax-free income funds, fixed income funds and multi-asset class funds. There are also ongoing 12b-1 service fees (and, in certain cases, distribution fees).

Class A Shares purchased subject to a front-end sales charge have no contingent deferred sales charge (CDSC). However, certain purchases of Class A shares made without a front-end sales charge may be subject to a CDSC of 1% if the shares are redeemed before the first day of the month in which the one year anniversary of the purchase falls. The CDSC is not reflected in the performance with maximum sales charge.

With Sales Charge - Returns with sales charges reflect applicable fees and expenses and include all distributions reinvested.

Without Sales Charge - Returns shown are without sales charges and have all distributions reinvested. If a sales charge had been deducted, the results would have been lower.

Returns shown at less than a year reflect aggregate total returns.

Double-Digit Returns - instances of high double-digit returns were achieved primarily during favorable market conditions and may not be sustainable over time.   

Indexes reflect total return, unless otherwise specified, with all dividends reinvested. Indexes are unmanaged, do not reflect the deduction of fees or expenses, and are not available for direct investment.

The Overall Morningstar RatingTM is derived from a weighted average of the performance figures associated with a fund's three-, five-, and 10-year (as applicable) Morningstar RatingTM metrics. © Morningstar, Inc. All rights reserved. The information contained herein (1) is proprietary to Morningstar and/or its content providers; (2) may not be copied or distributed; and (3) is not warranted to be accurate, complete or timely. Neither Morningstar nor its content providers are responsible for any damages or losses arising from any use of this information.

Morningstar proprietary ratings reflect historical risk-adjusted performance. For each fund with at least a three-year history, Morningstar calculates a Morningstar RatingTM based on a Morningstar risk-adjusted return measure that accounts for variation in a fund's monthly performance (including the effects of sales charges, loads and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. Load-waived ratings do not include any front-end sales charges (which are only available for certain defined contribution plans and certain mutual fund advisory programs) and should only be considered by investors who are not subject to sales loads. Not all funds with a load-waived rating may waive their front-end load. An investor should check with their advisor to determine if they are eligible to purchase the load-waived Class A share. The top 10% of the funds in an investment category receive 5 stars, 22.5% receive 4 stars, 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages). The Overall Morningstar rating is a weighted average of funds' three-, five-, and 10-year (as applicable) ratings. Past performance is no guarantee of future results. Morningstar Rating is for the Class A share only; other classes may have different performance characteristics.

Lipper Category Average - Peer group averages are based on universes of funds with the same investment objectives. The average return for the peer group is based on the returns of each individual fund within the group for the period shown. This average assumes reinvestment of dividends.

Fund Expense Ratio Detail: Reflects expenses for the Fund's fiscal year-end and is subject to change. Fund expenses may fluctuate with market volatility. A substantial reduction in Fund assets (since its most recently completed fiscal year), whether caused by market conditions or significant redemptions or both, will likely cause total operating expenses (as a percentage of Fund assets) to become higher than those shown.
