Stronghold Money Fund is a relatively new money market fund with about $400 million in total financial assets and shares outstanding (each maintained at a value of $1.00 per share). Most of the fund's accounts represent the savings of high-income, interest-sensitive investors. Stronghold's current distribution of financial assets currently is as follows: U.S. Treasury securities $170 million Federal agency securities 115 million Prime bank CDs 85 million Prime commercial paper issues 30 million Interest rates are expected to rise substantially in the money market over the next several weeks or months and Stronghold's management is concerned that its relatively low current yield (a seven-day average of 4.05 percent, one of the lowest yields among existing money funds) may result in the loss of many of its more interest-sensitive share accounts. The fund's average maturity is currently at 34 days, which is also substantially less than the industry's current average maturity of about 45 days.
