will be considered to have
the higher credit rating. The Fund may continue to hold securities that are downgraded in credit rating subsequent to their purchase if GW&K believes it would be advantageous to do so. While the
Fund may purchase debt securities of any duration, the Fund currently intends to primarily
invest in debt securities so that the overall duration of the Fund’s portfolio will remain +/- 20% of the duration of its benchmark, the Bloomberg U.S. Aggregate Bond Index. As of February 28, 2023, the duration of the
benchmark was 6.26 years. The average duration of debt securities in the Fund’s
portfolio may, however, be shorter or longer depending on market conditions.
The Fund may invest in debt securities issued by any of the following: public and private U.S. companies; the U.S. government and its agencies, such as the Federal
Home Loan Bank; and state and local governments issuing taxable municipal securities. The
Fund may also invest in asset-backed and mortgage-backed debt securities. The Fund may also invest in bonds whose proceeds are reserved for financing the implementation of the United Nations’
Sustainable Development Goals or other sustainable projects. GW&K’s investment process involves fundamental credit research and GW&K’s analysis of how the Fund’s potential investments
are affected by material environmental, social and governance (“ESG”) factors. In selecting potential investments for the Fund, GW&K uses top-down research that focuses on managing duration,
yield curve, credit quality, volatility and liquidity, as well as bottom-up research that
focuses on fundamental analysis, valuation analysis, technical analysis, and ESG factor analysis. GW&K may adjust its assessment of an investment based on a number of considerations.
GW&K applies its ESG factor analysis as one element of the investment process when selecting debt
securities issued by public and private U.S. companies and state and local governments
issuing taxable municipal securities, as well as bonds whose proceeds are reserved for financing the implementation of the United Nations’ Sustainable Development Goals or other sustainable projects, but not when
selecting debt securities issued by other types of issuers, including but not limited to
asset-backed and mortgage-backed debt securities and debt securities issued by the U.S.
government and its agencies, such as the Federal Home Loan Bank. GW&K has created its own
proprietary ESG Scoring System, which takes into consideration a range of factors,
including independent analysis from third parties such as MSCI Inc. and Sustainalytics, as well as its own analysis of material ESG factors. Each of GW&K’s sector specialists generally assesses the
materiality of relevant environmental, social and governance metrics to bond issues during the fundamental research process, depending on the sector and for corporate issuers the nature of the
company’s business. GW&K uses standards developed by the Sustainable Accounting
Standards Board to inform these assessments. Environmental assessment may take into account
issues such as carbon emissions, natural resource usage, hazardous waste, chemical safety,
water stress and sustainable technology. Social assessment may take into account issues such as human rights, labor relations, employee safety, product safety, data security and community relations. Governance
assessment may take into
account issues such as business ethics, board quality, board composition, compensation practices,
financial reporting and stakeholder governance.
GW&K recognizes that the relative impact of ESG factors on investment performance may vary across
market sector, industries and regions, but the firm believes that responsible corporate
behavior with respect to ESG factors can contribute to positive and sustainable long-term
financial performance. GW&K seeks to identify issuers that GW&K believes are leaders in their industries in effectively addressing exposure to ESG risks through business practices, policies and
programs, or issuers within an industry that have more limited exposure to ESG risks. The
goal of the ESG factor analysis is to seek investments with lesser exposure to, or better management of, ESG risks.
Principal Risks
There is the risk that you may lose money on your investment. All investments carry a certain amount of
risk, and the Fund cannot guarantee that it will achieve its investment objective. An
investment in the Fund is not a deposit or obligation of any bank, is not endorsed or
guaranteed by any bank, and is not insured by the Federal Deposit Insurance Corporation (“FDIC”) or any other government agency.
Below are some of the risks of investing in the Fund. The risks are presented in an order intended to facilitate readability and their order does not imply that the
realization of one risk is more likely to occur than another risk or likely to have a greater
adverse impact than another risk. The significance of any specific risk to an investment in
the Fund will vary over time, depending on the composition of the Fund’s portfolio, market conditions, and other factors. You should read all of the risk information presented below carefully,
because any one or more of these risks may result in losses to the Fund.
Debt Securities Risk—the value of a debt security changes in response to various factors, including, for example, market-related factors, such as changes in interest
rates or changes in the actual or perceived ability of an issuer to meet its obligations.
Investments in debt securities are subject to, among other risks, credit risk, interest rate risk, extension risk, prepayment risk and liquidity risk.
Market
Risk—market prices of investments held by the Fund may fall rapidly or unpredictably
due to a variety of factors, including economic, political, or market conditions, or other
factors including terrorism, war, natural disasters and the spread of infectious illness or
other public health issues, including epidemics or pandemics such as the COVID-19 pandemic, or in response to events that affect particular industries or companies.
Interest Rate Risk—fixed coupon payments (cash flows) of bonds and debt securities may become less competitive with
the market in periods of rising interest rates and cause bond prices to decline. During
periods of increasing interest rates, the Fund may experience high levels of volatility and shareholder redemptions, and may have to sell securities at times when it would otherwise not do so, and at unfavorable prices,
which could reduce the returns of the Fund.
