Performance data quoted represents past performance and does not guarantee future results. The investment return and principal value of an investment will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data quoted.

Important Risks: Investing involves risk, including the possible loss of principal. The net asset value (NAV) of the Fund's shares may fluctuate due to changes in the market value of the Fund's holdings. The Fund's share price may fluctuate due to changes in the relative supply of and demand for the shares on an exchange. The Fund is actively managed and does not seek to replicate the performance of a specified index. • Fixed income security risks include credit, liquidity, call, duration, and interest-rate risk. As interest rates rise, bond prices generally fall. • 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. Investors may be subject to the federal Alternative Minimum Tax as well as state and local income taxes. Capital gains, if any, are taxable. • The risks associated with mortgage-related and asset-backed securities include credit, interest-rate, prepayment, and extension risk. • 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. • The purchase of securities in the To-Be-Announced (TBA) market can result in additional price and counterparty risk. • Derivatives are generally more volatile and sensitive to changes in market or economic conditions than other securities; their risks include currency, leverage, liquidity, index, pricing, and counterparty risk. • Foreign investments may be more volatile and less liquid than U.S. investments and are subject to the risk of currency fluctuations and adverse political and economic developments. • The Fund may have high portfolio turnover, which could increase its transaction costs and an investor's tax liability. • In certain instances, unlike other ETFs, the Fund may effect creations and redemptions partly or wholly for cash, rather than in-kind, which may make the Fund less tax-efficient and incur more fees than an ETF that primarily or wholly effects creations and redemptions in-kind.

IOPV, or Indicative Optimized Portfolio Value, is a calculation disseminated by the stock exchange that approximates the Fund's NAV every fifteen seconds throughout the trading day.

Premium/discount reflects the relationship between an ETF's market price and its net asset value (NAV). Because ETFs are traded on an exchange, their market prices are in part driven by supply and demand dynamics. The ETF's market price may be above its NAV (reflecting a premium) or below its NAV (reflecting a discount).
