                                                               EXHIBIT 99.1



Date:             March 12, 2002

To:               All 401(k) Plan Participants

From:             National Steel Corporation

Sub:              National Steel Unitized Stock Fund

Participant directed investments, exchanges or other trades in the National
Steel Stock Fund have been suspended due to National Steel filing a
voluntary petition for relief under Chapter 11 of the Bankruptcy Code on
March 6, 2002 and a decision by the New York Stock Exchange to "de-list"
the National Steel Class B Common Stock effective at the end of trading on
Tuesday March 12, 2002.

National Steel Corporation is in the process of implementing a plan change
to equitably deal with this fund. While that process is taking place,
trading in the fund will remain suspended. It is anticipated that the fund
will continue to be an investment election after the suspension is lifted.
Currently, it is not possible to predict with certainty the length of time
that National Steel will operate under the protection of Chapter 11, the
outcome of the Chapter 11 proceedings in general, or the effect of the
proceedings on the business of the company or on the interests of the
various creditors and stakeholders. Under the priority scheme established
by the Bankruptcy Code, certain post-petition liabilities and pre-petition
liabilities need to be satisfied before shareholders can receive any
distribution. The ultimate recovery to shareholders, if any, will not be
determined until confirmation of a plan or plans of reorganization. There
can be no assurance as to what value, if any, will be ascribed to the NS
Class B common stock in the bankruptcy proceedings, and the value of the
equity represented by that stock could be substantially diluted or
canceled.

Plan participants may choose to modify their investment fund elections for
new contributions at this time. New elections can be made by calling
Fidelity at 800-835-5092 or by using the Fidelity web site at www.401k.com.
For represented participants, changes made prior to 3/14/2002 will be
applied to your contributions from February 2002 that have not been
transferred to Fidelity (and will be transferred on 3/15/2002).

All investment elections to the Stock Fund for future contributions shall
be directed to the Fidelity Cash Reserves. After the plan changes are
finalized, these contributions will be handled according to the appropriate
plan provisions.

National Steel is in the process of implementing a plan change to equitably
deal with participant equity in this fund. Further communications will be
mailed to your home in the very near future. Please look for this
information from Fidelity.
