Lipper rankings are based on total return without sales charge relative to all share classes of funds with similar objectives as determined by Lipper. Past performance is not indicative of future results.

Morningstar Ratings for the specific share classes only; other classes may have different performance characteristics.

The Morningstar Rating™ 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 3-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 Morningstar Rating does not include any adjustment for sales loads. 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 3-, 5-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% 3-year rating for 36–59 months of total returns, 60% 5-year rating/40% 3-year rating for 60–119 months of total returns, and 50% 10-year rating/30% 5-year rating/20% 3-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 3-year period actually has the greatest impact because it is included in all three rating periods.

Some of Morningstar's proprietary calculations, including the Morningstar Rating™, are not customarily calculated based on adjusted historical returns. However, for new share classes/channels, Morningstar may calculate an extended performance Morningstar Rating that is based, in part, on adjusted historical (or "pre-inception") returns for periods prior to the inception of the share class of the fund shown herein ("Report Share Class").

The extended performance is calculated by creating a performance stream consisting of the Report Share Class and older share class(s). Morningstar adjusts the historical total returns of the older share class(es) of a fund to reflect higher expenses in the Report Share Class. Morningstar does not hypothetically adjust returns upwards for lower expenses.

The extended performance Morningstar Risk-Adjusted Return is then calculated for 3-, 5-, and 10-year time periods and used to determine the extended performance Morningstar Rating. The extended performance Morningstar Rating for this fund does not affect the retail fund data published by Morningstar, as the bell curve distribution on which the ratings are based includes only funds with actual returns. The Overall Morningstar Rating for multi-share open-end funds will be either based on actual performance only or extended performance only. Once the share class turns three years old, the Overall Morningstar Rating will be based on actual ratings only. The Overall Morningstar Rating for multi-share variable annuities is based on a weighted average of any ratings that are available.

While the inclusion of pre-inception data, in the form of extended performance, can provide valuable insight into the probable long-term behavior of newer share classes of a fund, investors should be aware that an adjusted historical return can only provide an approximation of that behavior. For example, the fee structures of a retail share class will vary from that of an institutional share class, as retail shares tend to have higher operating expenses and sales charges. These adjusted historical returns are not actual returns. The underlying investments in the share classes used to calculate the pre-performance string will likely vary from the underlying investments held in the fund after inception. Calculation methodologies utilized by Morningstar may differ from those applied by other entities, including the fund itself.

The up-market capture ratio is used to evaluate how well an investment manager performed relative to an index during periods when that index has risen. The ratio is calculated by dividing the manager’s returns by the returns of the index during the up-market, and multiplying that factor by 100. The down-market capture ratio is used to evaluate how well an investment manager performed relative to an index during periods when that index has dropped. The ratio is calculated by dividing the manager’s returns by the returns of the index during the down-market and multiplying that factor by 100.

Consider these risks before investing: The value of investments in the fund’s portfolio may fall or fail to rise over extended periods of time for a variety of reasons, including general economic, political, or financial market conditions; investor sentiment and market perceptions; government actions; geopolitical events or changes; and factors related to a specific issuer, geography, industry, or sector. These and other factors may lead to increased volatility and reduced liquidity in the fund’s portfolio holdings.

The fund’s performance will be closely tied to the economic and political conditions in Massachusetts, and can be more volatile than the performance of a more geographically diversified fund. To the extent the fund invests in securities of issuers located outside of Massachusetts, the fund may also be exposed to the risks affecting other states. Capital gains, if any, are taxed at the federal and, in most cases, state levels. For some investors, investment income may be subject to the federal alternative minimum tax. Bond investments are subject to interest-rate risk (the risk of bond prices falling if interest rates rise) and credit risk (the risk of an issuer defaulting on interest or principal payments). Interest-rate risk is generally greater for longer-term bonds, and credit risk is generally greater for below-investment-grade bonds. Unlike bonds, funds that invest in bonds have fees and expenses. Tax-exempt bonds may be issued under the Internal Revenue Code only by limited types of issuers for limited types of projects. As a result, the fund’s investments may be focused in certain market segments and be more vulnerable to fluctuations in the values of the securities it holds than a more broadly invested fund. Interest the fund receives might be taxable.

Our investment techniques, analyses, and judgments may not produce the outcome we intend. The investments we select for the fund may not perform as well as other securities that we do not select for the fund. We, or the fund’s other service providers, may experience disruptions or operating errors that could have a negative effect on the fund. You can lose money by investing in the fund.

Credit qualities are shown as a percentage of net assets. A bond rated BBB or higher (SP-3 or higher, for short-term debt) is considered investment grade. This chart reflects the highest security rating provided by one or more of Standard & Poor's, Moody's, and Fitch. Ratings may vary over time. Cash and net other assets, if any, represent the market value weights of cash, derivatives, and short-term securities in the portfolio. The fund itself has not been rated by an independent rating agency.
