Consider Prime Rate Funds for More Income

Prime-rate funds are closed-end mutual funds that seek to provide yields that match the prime rate. This attractive yield is often more than twice the federal funds rate and somewhat higher than the rate on five-year certificates of deposit (CDs). Read on to find out why investors seeking income-generating portfolios may find prime-rate funds worth a second look.

How Yield Is Generated

To achieve such high yields, prime-rate funds invest in floating-rate, secured corporate loans. These loans have been made by commercial banks and insurance companies to corporations that are in less-than-perfect financial situations. In addition to borrowing money from the banks or insurance companies, the corporations may also have borrowed money by issuing below-investment-grade bonds, commonly referred to as junk bonds. While the corporate loans underlying prime-rate funds are backed by collateral, the use of junk bonds for financing makes a statement about the financial health of these corporations.


The bonds that prime-rate funds purchase are often referred to as senior debt, because they are backed by collateral, and, in the event the bond issuer goes bankrupt, holders of senior debt must be repaid before other creditors. While this status does not guarantee complete repayment, it generally means that investors receive the bulk of their money if bankruptcy occurs.

The yields rise and fall with changes in short-term interest rates, so the share price remains stable, generally not fluctuating by more than a few cents. Traditional fixed-rate bonds lose value when interest rates rise, because investors are willing to purchase the lower-yielding bonds only if they get a discount on the price. Not only do prime-rate funds tend to hold their value and enjoy low volatility, but they also provide a hedge against rate hikes, since their yield moves with the market.

Prime-rate funds hold a large number of loans in their portfolios. This diversification means that if one of the underlying corporations declares bankruptcy, the overall impact to the portfolio will be minimal.


At the other end of the spectrum, bankruptcy of any of the underlying bond issuers can result in a loss. While senior debt holders are first in line for a claim on assets, recovery will be less than 100%.

Another factor to consider is that redemptions are permitted only on a monthly or sometimes quarterly basis. This illiquidity means that an investor's ability to access money is restricted. (See also: Debt Reckoning.)

These funds also often have higher-than-average expense ratios and levy redemption fees if investors seek to pull their money out prior to meeting a required minimum holding time.

Another potential cost is that, while these funds seek to maintain a steady share price, they sometimes trade at a premium or a discount. If you are buying when the fund trades at a premium or redeeming when it trades at a discount, you are either spending more than the underlying assets are worth or receiving less than full value for your holdings.

Trading strategies are another noteworthy item. In order to achieve their attractive returns, these funds invest in private loans issued to companies that, if they were rated by an agency, would have bond ratings classified as junk. Remember, the loans purchased by prime-rate funds are backed by collateral, unlike junk bonds, but the issuers themselves are in less-than-stellar financial health. To purchase these loans, the funds often engage in leverage, a practice that can magnify both gains and losses.

The Bottom Line

While prime-rate funds are accompanied by a host of potentially scary negatives, these funds have a solid track record of delivering on their promises. Returns often rank about 2% higher than the returns on money market funds. They may be worth consideration by investors seeking low volatility and a steady, predictable source of income based on interest rates that are higher than average. They are not a good choice for investors seeking easy and frequent access to their money.

Prime-rate funds are a bit more sophisticated than many other mutual funds. Their complexity results in a lot of factors that must be taken into consideration before making a purchase. Like all investments, whether simple or complex, investors should take the time to learn about all aspects of the investment before committing their cash. Taking measured risks is part of the investing process, but buying something that you do not completely understand is never a good idea.
