Moody's Investment Grade

1. A ratings system used by Moody's to gauge the risk of municipal bonds and the creditworthiness of their issuers. The ratings are number one through four, with a one (MIG 1) representing the highest quality and a four (MIG 4) representing the lowest quality.

2. In other bonds, a rating higher than Baa, indicating that the issue is sufficiently low risk as to allow banks to invest in them. See: Investment-grade.
