Performance data quoted represents past performance, which does not guarantee future results. Current performance may be lower or higher than the figures shown. Principal value and investment returns will fluctuate, and investors' shares, when redeemed, may be worth more or less than the original cost. Performance would have been lower if fees had not been waived in various periods. Total returns assume the reinvestment of all distributions and the deduction of all Fund expenses. Returns with sales charge reflect a deduction of the stated maximum sales charge. Returns without sales charge would have been lower had sales charges been reflected. An investor cannot invest directly in an index, and unmanaged index returns do not reflect any fees, expenses or sales charges. Returns for periods of less than one year are not annualized.

Distributions per Share ($)

Year

Tax Information
Record Date	Ordinary Dividends Dividends paid by a fund that are derived from interest, dividends, net short-term capital gains and other types of ordinary income earned by the fund. For a fund that elects to pass through its foreign taxes paid (a non-cash item), a shareholder's allotted share of foreign taxes has been added to the “Ordinary Dividends” cash distributions received by the shareholder. If the fund passed through foreign taxes paid and later is refunded any portion of those taxes by a foreign tax authority, any interest paid to the fund on that refund is also required to be included in “Ordinary Dividends”.	Qualified Dividends The portion of a fund’s “Ordinary Dividends” that may be eligible for a reduced capital gain tax rate. To be eligible for the lower tax rates, certain holding periods apply and shareholders should consult their tax advisor to determine the amount eligible for the reduced rate. This amount represents both cash distributions and non-cash amounts, such as foreign taxes paid, that have been allocated to shareholders.	Capital Gain Distributions	Unrecaptured Section 1250 Gain	Non-Taxable Return Of Capital	Section 199a Dividends The portion of a fund’s “Ordinary Dividends” generated by a real estate investment trust or earned by a fund from its investments in real estate investment trusts, subject to limitations. Individual (non-corporate) shareholders may be entitled to a special deduction from gross income for “Section 199A Dividends” received from a fund. To qualify for this deduction certain holding periods apply and shareholders should consult their tax advisor.	Foreign Tax Paid	Exempt Interest Dividends	Interest on Tax Reclaim Refunds

Risks

All investments involve risks, including possible loss of principal. Fixed income securities involve interest rate, credit, inflation and reinvestment risks, and possible loss of principal. As interest rates rise, the value of fixed income securities falls. Asset-backed, mortgage-backed or mortgage-related securities are subject to prepayment and extension risks. Low-rated, high-yield bonds are subject to greater price volatility, illiquidity and possibility of default. Derivative instruments can be illiquid, may disproportionately increase losses, and have a potentially large impact on performance. Leverage increases the volatility of investment returns and subjects investments to magnified losses and a decline in value. International investments are subject to special risks, including currency fluctuations and social, economic and political uncertainties, which could increase volatility. These risks are magnified in emerging markets. These and other risks are discussed in the fund’s prospectus.

Footnotes

Net Asset Value - the amount per share you would receive if you sold shares that day. NAV Change indicates a change in the Net Asset Value from the previous business day.
Figures are aggregate total return figures, have not been annualized and represent the change in value of an investment over the period indicated.
The Morningstar Rating™ for funds, or “star rating”, is calculated for managed products with at least a three-year history, and subject to change monthly. 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 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 return, 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 return. 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. Ratings do not take into account the effects of sales charges and loads. Morningstar Rating is for the specified share class(es) only; other classes may have different performance characteristics.
Distribution Rate is calculated by annualizing the daily accrual, divided by the NAV as of the date indicated. The Distribution Rate calculation includes income and return of capital, and excludes special distributions. The Distribution Rate is not guaranteed, subject to change, and is not a quotation of fund performance.
During periods of rising inflation, fund yields can vary significantly from month-to-month and may not be repeated.
With Waiver means the performance quote reflects any applicable expense reductions and fee waivers.
30-Day SEC Yield is calculated using the net income (interest and dividends) per share earned over a trailing 30-day period (annualized), divided by the fund’s share price at the end of that period. It may not equal the fund’s actual income distribution rate, which reflects the fund’s past dividends paid to shareholders.
Gross Expense Ratio reflects the total annual operating expenses for the share class shown, prior to the deduction of any waiver or reimbursement. Actual expenses may be higher and may impact portfolio returns. Net Expense Ratio reflects total expenses after any fee waivers, implemented expense caps or reimbursements. If a fund has contractual fee waivers, expense caps and/or reimbursements, the expiration date can be found by clicking on the information button next to the net expense ratio. Additional amounts may be voluntarily waived and/or reimbursed and may be modified or discontinued at any time without notice. Expense ratios are as of the most recent prospectus or annual report.
Net Expense Ratio represents the expense ratio applicable to investors.
Public Offering Price – the purchase price for each share of the fund on a given day. It includes the maximum initial sales charge, if any.
Credit Quality is a measure of a bond issuer's ability to repay interest and principal in a timely manner. The credit ratings shown are based on each portfolio security's rating as provided by S&P Global Ratings, Moody's Investors Service and/or Fitch Ratings, Inc. and typically range from AAA (highest) to D (lowest), or an equivalent and/or similar rating. For this purpose, if two or more of the agencies have assigned differing ratings to a security, the highest rating is used. Securities that are unrated by all three agencies are reflected as such. The credit quality of the investments in the portfolio does not apply to the stability or safety of the portfolio. The methodology used for the calculation of credit quality ratings displayed may differ from the methodology for monitoring investment limits, if applicable. Please note, the portfolio itself has not been rated by an independent rating agency.
