RAVI invests in a broad array of short-term, investment grade debt securities from around the world, despite being focused mainly on US dollar-denominated debt. The fund may invest without limitation in developed markets and up to 20% of its assets in emerging markets. It seeks higher income while preserving capital, with an emphasis on the latter. The portfolio has an average duration of less than one year, while its weighted average maturity typically does not exceed two years. As actively managed funds do, RAVI can make certain investment decisions at its discretion. The fund may, at times, hold sizeable positions in cash and lend securities of up to one-third of the funds total assets. Prior to January 3, 2023, the fund was named FlexShares Ready Access Variable Income Fund.
