Research house Lonsec has maintained its investment grade rating for the MFS Premium Income Fund (MFSIM) following a recent review.
MFSIM fund manager Marilyn Watts said the fund was unaffected by this year's financial market volatility and credit crunch.
The $796 million fund had been structured for income dependability for investors who wanted monthly distributions, Lonsec said.
MFSIM invests in commercial loans, property-backed managed investment schemes, assets, cash and fixed interest securities.
