VRIG has an active strategy, which is aimed at generating high current income. VRIG's manager uses proprietary models to tactically and strategically allocate across a wide array of USD-denominated investment-grade variable-rate instruments, such as agency- and non-agency-backed securities, agency credit risk transfers and debt securities, and floating-rate Treasury securities, etc. Variable-rate securities are less sensitive to changes in interest rates due to their periodic coupon adjustment feature. Despite the investment-grade claim in its name, the fund can hold up to 20% in non-investment-grade variable-rate securities and fixed-rate securities of all credit ratings.
