RIGS has a long leash when it comes to portfolio composition. This is not unusual for the fixed-income space, which has seen a surge in actively managed funds, perhaps due to the view that the less liquid, less efficient bond space lends itself to active management. RIGS can hold almost any type of fixed-income security without regard to type of issuer, credit rating, country of issue, currency of issue or maturity. The only exposure guideline is a wide duration preference of 2 to 10 years. As such, things like average credit rating, yield, and maturity are all highly variable.
