OPPENHEIMER MUNICIPAL BOND FUND
Supplement dated July 30, 1998 to the Statement of Additional
Information dated November 24, 1997
This Supplement dated July 30, 1998 to the Statement of Information dated
November 24, 1997 changing the Statement of Additional Information is as follows
1. The last paragraph within the section titled "Private Activity Municipal
Series" on page six is deleted and replaced with the following:
The Federal alternative minimum tax is designed to ensure that all
taxpayers pay some tax, even if their regular tax is zero. This is accomplished
in part by including in taxable income certain tax preference items in arriving
at alternative minimum taxable income. The Tax Reform Act made tax-exempt
interest from certain private activity bonds a tax preference item for purposes
of the alternative minimum tax on individuals and corporations. Any
exempt-interest dividend paid by a regulated investment company will be treated
as interest on a specific private activity bond to the extent of its
proportionate share of the interest on such bonds received by the regulated
investment company. The U.S. Treasury is authorized to issue regulations
implementing this provision. In addition, corporate taxpayers subject to the
alternative minimum tax may, under some circumstances, have to include
exempt-interest dividends in calculating their alternative minimum taxable
income in situations where the "adjusted current earnings" of the corporation
exceeds its alternative minimum taxable income. The Fund may hold Municipal
Securities the interest on which (and thus a proportionate share of the
exempt-interest dividends paid by the Fund) will be subject to the Federal
alternative minimum tax on individuals and corporations.
