Supplement to Nov. 1, 1998 Statement of Additional Information
The description of participation interests (pages 8-9 in this
Statement of Additional Information) has been revised to read as
follows:
PARTICIPATION INTERESTS
Each Fund may purchase participation interests in all or part
of specific holdings of Municipal Securities, but does not intend
to do so unless the tax-exempt status of those participation
interests or certificates of participation is confirmed to the
satisfaction of the Board of Trustees, which may include
consideration of an opinion of counsel as to the tax-exempt
status. Each participation interest would meet the prescribed
quality standards of the Fund or be backed by an irrevocable
letter of credit or guarantee of a bank that meets the prescribed
quality standards of the Fund. (See Investment Policies.) Some
participation interests are illiquid securities.
Each Fund may also purchase participations in lease
obligations or installment purchase contract obligations
(hereinafter collectively called "lease obligations") of municipal
authorities or entities. Although lease obligations do not
constitute general obligations of the municipality for which the
municipality's taxing power is pledged, a lease obligation is
ordinarily backed by the municipality's covenant to budget for,
appropriate, and make the payments due under the lease obligation.
However, certain lease obligations contain "non-appropriation"
clauses which provide that the municipality has no obligation to
make lease or installment purchase payments in future years unless
money is appropriated for such purpose on a yearly basis. In
addition to the "non-appropriation" risk, these securities
represent a relatively new type of financing that has not yet
developed the depth of marketability associated with more
conventional bonds. Although "non-appropriation" lease
obligations are secured by leased property, disposition of the
property in the event of foreclosure might prove difficult.
The Board of Trustees has delegated to the Adviser the
responsibility to determine the credit quality of participation
interests. The determinations concerning the liquidity and
appropriate valuation of a municipal lease obligation, as with any
other municipal security, are made based on all relevant factors.
These factors may include, among others: (1) the frequency of
trades and quotes for the obligation; (2) the number of dealers
willing to purchase or sell the security and the number of other
potential buyers; (3) the willingness of dealers to undertake to
make a market in the security; and (4) the nature of the
marketplace trades, including the time needed to dispose of the
security, the method of soliciting offers, and the mechanics of
transfer.
