This Form 6-K consists of the following:

1.   Press release of ABB Ltd, dated September 9, 2004, announcing approval by
     its bondholders of resolutions that give it the option to redeem certain
     outstanding bonds issued by ABB International Finance Limited.

This report includes forward-looking information and statements that are subject
to risks and uncertainties that could cause actual results to differ. These
statements are based on current expectations, estimates and projections about
global economic conditions, the economic conditions of the regions and
industries that are major markets for ABB Ltd and ABB Ltd's lines of business.
These expectations, estimates and projections are generally identifiable by
statements containing words such as "expects," "believes," "estimates" or
similar expressions. Important factors that could cause actual results to differ
materially from those expectations include, among others, ABB's ability to
dispose of certain of its non-core businesses on terms and conditions acceptable
to it, ABB's ability to further reduce its indebtedness as planned, the
resolution of asbestos claims on terms and conditions satisfactory to ABB,
economic and market conditions in the geographic areas and industries that are
major markets for ABB's businesses, market acceptance of new products and
services, changes in governmental regulations, interest rates, fluctuations in
currency exchange rates and such other factors as may be discussed from time to
time in ABB's filings with the U.S. Securities and Exchange Commission,
including its annual reports on Form 20-F. Although ABB Ltd believes that its
expectations reflected in any such forward-looking statement are based upon
reasonable assumptions, it can give no assurance that those expectations will be
achieved.

ABB bondholders pass resolutions to permit
repurchases


Zurich, Switzerland, September 9, 2004 - ABB, the leading power and automation
technology group, said bondholders earlier today approved resolutions which give
the company the option to redeem outstanding instruments of its Euro 300
million, 5.375 percent bonds due in 2005 and Euro 475 million, 5.125 percent
bonds due in 2006.

The prices will be calculated on the same terms as the tender offers announced
on 29 July 2004. Both bonds were issued by ABB International Finance Limited.

Peter Voser, ABB's chief financial officer, said: "The completion of this bond
repurchase will reduce ABB's debt by approximately $800 million and is part of
ABB's strategy to cut gross debt to $4 billion by the end of 2005."

Prior to the bondholders' meetings, 57 percent (Euro 156,591,000) of the
principal amount outstanding of 2005 bonds and 59 percent (Euro 215,200,000) of
the principal amount outstanding of 2006 bonds had been validly tendered and
accepted under the tender offers, for which pricing and settlement dates are
scheduled for 10 and 14 September 2004 respectively.

ABB intends to exercise its options to redeem early all of the remaining
outstanding 2005 and 2006 bonds. The redemption date is expected to be 29
September 2004, with the calculation of the relevant redemption amounts
scheduled for 27 September 2004.

Further information can be found online at www.ABBbondtender.com or by
contacting ABB or the dealer managers. A notice will also be published in the
Luxemburger Wort on 14 September 2004.

Mandated dealer managers for the transaction are Barclays Capital, Commerzbank
Securities and Dresdner Kleinwort Wasserstein.
