A release entitled, "Moody's assigns Aaa to HighMark Treasury Plus Money Market Fund" says, "Moody's Investors Service has assigned a money market fund rating of Aaa to HighMark Treasury Plus Money Market Fund. The rating reflects the high credit quality, strong liquidity profile and limited market risk exposure of the fund as well as the effective investment process and adequate risk management structure of the advisor. The fund seeks current income while preserving capital and liquidity. In line with its mandate, the fund invests in US Treasury securities or overnight repurchase agreements collateralized with treasury securities. In addition the fund may invest up to 20% in other securities that are issued or guaranteed by the US government.... The fund currently has approximately $200 million in assets under management which are largely sourced through relationships with the advisor's parent, Union Bank N.A.. Although this fund has had concentrated exposure to certain repurchase agreement counterparties and has some shareholder concentration given the small size of the fund, the high credit quality and the liquid nature of the securities that can be purchased by this fund combine to mitigate the resulting risk."
