Important Risks: Investing involves risk, including the possible loss of principal. Security prices fluctuate in value depending on general market and economic conditions and the prospects of individual companies. • Fixed income security risks include credit, liquidity, call, duration, and interest-rate risk. As interest rates rise, bond prices generally fall. • Obligations of U.S. Government agencies are supported by varying degrees of credit but are generally not backed by the full faith and credit of the U.S. Government. • Mortgage-related and asset-backed securities' risks include credit, interest-rate, prepayment, and extension risk. • Municipal securities may be adversely impacted by state/local, political, economic, or market conditions; these risks may be magnified if the Fund focuses its assets in municipal securities of issuers in a few select states. • Applying sustainability criteria to the investment process may result in foregoing certain investments and underperformance comparative to funds that do not have a similar focus. There is a risk that the securities identified by the sub-adviser as meeting its sustainable investing criteria do not operate as anticipated. • The Fund may have high portfolio turnover, which could increase its transaction costs and an investor's tax liability. • The value of inflation-protected securities (IPS) generally fluctuates with changes in real interest rates, and the market for IPS may be less developed or liquid, and more volatile, than other securities markets. • Investments in high-yield ("junk") bonds involve greater risk of price volatility, illiquidity, and default than higher-rated debt securities. • Changes related to LIBOR could have an adverse impact on financial instruments that reference this rate. • The purchase of securities in the To-Be-Announced (TBA) market can result in higher portfolio turnover and related expenses as well as price and counterparty risk. • Loans can be difficult to value and less liquid than other types of debt instruments; they are also subject to nonpayment, collateral, bankruptcy, default, extension, prepayment and insolvency risks. • Foreign investments, including foreign government debt, may be more volatile and less liquid than U.S. investments and are subject to the risk of currency fluctuations and adverse political, economic and regulatory developments.
