| Strategy Narrative [Text Block] | In seeking capital preservation, the Fund will normally invest at least 80% of its assets in a diversified portfolio of debt securities (commonly referred to as “bonds”) of varying maturity, duration, and quality. Under normal conditions, the Fund intends to pursue a defensive strategy of limiting its interest-rate sensitivity by maintaining a portfolio duration of three years or less. Because of events affecting the bond markets and interest rate changes, the duration of the portfolio might not meet the target at all times. The Fund may also invest in investment companies such as ETFs, which could represent a significant percentage of assets. The Fund invests primarily in short- and intermediate-term investment-grade fixed-income securities. These may include U.S. and non‑U.S. investment-grade corporate debt securities, U.S. and non‑U.S. government debt securities, and mortgage-backed and asset-backed securities. In most market environments, the Fund will not invest more than 20% of assets in fixed-income securities that are rated below investment grade (commonly known as junk bonds), or if unrated, are determined by the Fund’s subadviser(s) to be of comparable quality. In addition, the Fund may invest a significant portion of its assets in collateralized debt obligations (CDOs), including collateralized loan obligations (CLOs). CDOs are types of asset-backed securities. CLOs are ordinarily issued by a trust or other special purpose entity and are typically collateralized by a pool of loans, which may include, among others, domestic and non‑U.S. senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans, held by such issuer. Multimanager Approach—The Fund uses a multimanager approach, meaning the adviser may allocate assets to one or more subadvisers, in addition to open- and closed‑end investment companies, ETFs, and individual securities (collectively “Allocation Decisions”). The adviser and each subadviser acts independently from the others and uses its own investment style and process to select securities, within the constraints of the Fund’s investment objective, strategies, and restrictions. Morningstar is responsible for selecting the investment strategies and making Allocation Decisions, with the goal of maximizing return in the context of pursuing the Fund’s investment objective with a prudent level of risk for the strategy. Morningstar may change subadvisers, subject to the oversight of the board of trustees, and sell holdings at any time.
