Several closed end funds have suspended distribution to shareholders. The operational risks from closed end funds have surfaced due to the severe decline in assets and credit crises. I have noted to this when I have talked about investing high yield closed end funds. The problem is
... closed-end funds must maintain asset coverage of at least 200% with respect to senior securities, such as auction-rate preferred securities. That means for each $1 of preferred stock issued, a fund must have at least $2 in assets. A fund is prohibited from declaring or paying a dividend that would put it below the 200% asset-coverage ratio.However, most of these dividends are postponed and will resume once asset prices correct.
As a result of the market's declines, the Pimco funds' asset-coverage ratios have fallen below the required 200% level, the firm said.
