There are no limits on the rate of portfolio turnover, and investments may be sold without regard to length of time held when investment considerations warrant such action. A higher portfolio turnover rate may result in correspondingly greater brokerage commissions and other transactional expenses that are borne by each Fund. In addition, high portfolio turnover may result in the realization of net short-term capital gains by a Fund which, when distributed to shareholders, will be taxable as ordinary income for U.S. federal income tax purposes or may result in greater amounts of net capital gain distributions.
