Item 2


The right time to take the next step


Dear shareholders,

The time has come for ABB to take the next step along the road to long-term
profitable growth. This is why we have called an extraordinary general meeting
of shareholders for November 20, 2003.

The cornerstone of our plan is to raise more than US$ 2 billion in additional
equity by issuing new ABB shares. The funds raised by this proposed capital
increase will be used to grow our core businesses and refinance the balance
sheet, allowing us to restore our investment-grade credit rating.

We need the support of you, our shareholders, to make this a success.

Over the past 12 months, we have made steady progress. Today, we are a stronger
ABB Group. Our core power and automation technologies businesses report solid
earnings growth. We have improved our cost competitiveness, successfully
divested non-core businesses, and made significant progress towards the
settlement of the difficult asbestos issue.

Now we want to take the next major step by significantly strengthening the
Group's capital structure. The aim is to provide our core businesses with the
financial flexibility they need to continue profitable growth. This also means
value growth for you, our shareholders.

There are two additional elements in our plan to put the company's capital
structure back on a sound base.

First, we have obtained a new US$ 1 billion credit facility with our banks,
improving our credit arrangements. The new 3-year credit facility is intended as
a "back-stop". This means that we don't expect to draw on it, but it will
provide the ABB Group with the financial flexibility needed in today's
competitive environment.

Second, if conditions in the financial markets are favorable, we intend to issue
a new bond to raise additional capital. We will use these proceeds to adjust our
debt repayment schedule over the coming years, further contributing to a stable
debt maturity profile of between US$ 750 million and US$ 1 billion per year.

Let me explain how this new capital fits into our longer-term strategy and why
now is the right time to act.

Late last year we decided to focus ABB on our two most competitive businesses
with the greatest potential for growth - the Power Technologies and Automation
Technologies divisions. We simplified the organization so we could be more
efficient, take decisions faster and serve our customers better.


We also began a cost-reduction program aimed at saving US$ 900 million a year
starting in the middle of 2004. As of September of this year, we have saved more
than US$ 400 million and are ahead of schedule to reach our target.

We started a process last year of selling businesses not directly related to our
core divisions, using the money to pay down our debt. It began with our
Structured Finance business that we sold for more than US$ 2 billion. This year
we have sold or are preparing to sell most of our remaining non-core businesses.

In addition, our U.S. subsidiary, Combustion Engineering filed a Chapter 11 Plan
of Reorganization in the U.S. bankruptcy courts earlier this year to resolve its
asbestos liabilities. The plan was endorsed in a vote by the vast majority of
claimants and recommended for approval by the bankruptcy court in July before
being approved by the respective U.S. district court. The case is now in a
fast-track process before the 3rd U.S. Circuit Court of Appeals, which has
scheduled a hearing for December 16. We remain confident that the plan will be
approved.

On the back of these positive developments, the launch of a convertible bond at
the end of August marked our successful comeback in the capital market. The
proceeds of about CHF 1 billion cover our outstanding debt maturities during the
rest of 2003. We view the market's positive reaction to the convertible bond as
an endorsement of our strategy.

Last but not least, our core divisions continue to show higher revenues,
earnings and cash flow, and lower costs, all despite difficult markets. These
operational improvements position us to take advantage of improving economic
conditions when they come.

The final detailed terms for the proposed capital increase, including the offer
price for a new share, will be communicated by the morning of the extraordinary
general meeting of shareholders. The subscription period during which new shares
may be purchased would begin shortly after the extraordinary shareholder meeting
and last for about two weeks. The new shares would begin trading shortly
thereafter.

Today, ABB is a more focused company, with improved operational earnings and
cash flow, and greater cost competitiveness. We have rebuilt a solid base for
future growth. Today's proposed equity increase would give us the flexibility we
need to grow with confidence. Now is the time to take the next step.

On behalf of the Board of Directors, I encourage you to support our proposal to
increase ABB's capital base through this offering of new shares at the
extraordinary general meeting.


Sincerely,



Jurgen Dormann
Chairman of the Board of Directors, Chief Executive Officer, ABB Ltd
