Such issuers include, without limitation, U.S. and non-U.S. governments and their agencies, instrumentalities or sponsored enterprises, U.S. state and local governments and municipalities, and U.S. and non-U.S. private-sector entities, such as corporations and banks. The average portfolio duration of this Fund will vary based on The Northern Trust Company Investment Policy Committees forecast for interest rates and will normally not exceed one year. Duration measures the price sensitivity of a fixed-income security to changes in interest rates. Interest rate changes have a greater effect on the price of fixed-income securities with longer durations. The dollar-weighted average portfolio maturity of the Fund is normally not expected to exceed two years. The Fund invests in investment grade debt securities (i.e., securities that are, at the time of investment, rated within the top four rating categories by a Nationally Recognized Statistical Rating Organization (NRSRO) or of compa rable quality as determined by NTI). The Fund may invest, without limitation, in fixed-income securities and instruments of foreign issuers in developed markets, including debt securities of foreign governments, and may invest more than 25% of its total assets in securities and instruments of issuers in a single developed market country. The Fund may invest up to 20% of its total assets in fixed-income securities and instruments of issuers in emerging markets. The Fund may invest, without limitation, in mortgage- or asset-backed securities, including to-be-announced (TBAs) transactions, and purchase and sell securities on a when-issued, delayed delivery or forward commitment basis. However, the Fund will not invest more than 10% of its total assets in non-agency mortgage or asset-backed securities. The Fund also may, without limitation, seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts (such as buy backs or mortgage dollar rolls). The Fund may engage in forward foreign currency transactions for hedging purposes in order to protect against uncertainty in the level of future foreign currency exchange rates, to facilitate local settlements or to protect against currency exposure in connection with its distributions to shareholders. The Fund, however, does not expect to engage in currency transactions for speculative purposes (e.g., for potential income or capital gain). In seeking to achieve its investment objective, the Fund may invest in U.S. Treasury futures contracts, which are considered to be derivative instruments, for various purposes, including to manage duration, credit and interest rate risks, and for cash management. The Fund is an actively managed ETF that does not seek to replicate the performance of a specified index. The Fund may have a higher degree of portfolio turnover than funds that seek to replicate the performance of an index. The Fund may lend securities representing up to one-third of the value of the Funds total assets (including the value of the collateral received). From time to time the Fund may focus its investments ( i.e. , invest more than 15% of its total assets) in one or more particular sectors. As of December 31, 2025 , the Fund focused its investments in the Financial sector. Show less
