Exception to holding period requirement for certain regularly declared exempt-interest dividends

Except as otherwise provided by regulations, subparagraph (B) shall not apply with respect to a regular dividend paid by a regulated investment company which declares exempt-interest dividends on a daily basis in an amount equal to at least 90 percent of its net tax-exempt interest and distributes such dividends on a monthly or more frequent basis.

In the case of a regulated investment company (other than a company described in clause (i)) which regularly distributes at least 90 percent of its net tax-exempt interest, the Secretary may by regulations prescribe that subparagraph (B) (and subparagraph (C) to the extent it relates to subparagraph (B)) shall be applied on the basis of a holding period requirement shorter than 6 months; except that such shorter holding period requirement shall not be shorter than the greater of 31 days or the period between regular distributions of exempt-interest dividends.
