ICI.org – Washington, DC, –Beginning this month, the Investment Company Institute’s (ICI) monthly press release and Taxable Money Market Fund Portfolio report will utilize a new format and provide new data. ICI’s press release and tables will now include additional types of securities; dollar-based reporting; and monthly rather than weekly reporting of liquidity. These changes reflect the new reporting requirements on the Securities and Exchange Commission’s revised Form N-MFP. This report will be published in the middle of each month, reporting aggregated data for the prior month.

As of the final Friday in May, prime money market funds held 30.8 percent of their portfolios in daily liquid assets and 46.3 percent in weekly liquid assets, while government money market funds held 57.6 percent of their portfolios in daily liquid assets and 73.9 percent in weekly liquid assets.

At the end of May, prime funds had a weighted-average maturity of 31 days and a weighted-average life of 46 days. Average WAMs and WALs are asset-weighted. Government money market funds had a weighted-average maturity of 39 days and a weighted-average life of 96 days.
