ICI's latest "Money Market Fund Assets" report shows assets flat in the latest week after two weeks of increases and six weeks of declines.

Among taxable money market funds, government funds decreased by $934 million and prime funds decreased by $867 million. Tax-exempt money market funds increased by $660 million."
