Exhibit 99.1

STATEMENT UNDER OATH OF PRINCIPAL EXECUTIVE OFFICER REGARDING FACTS AND
CIRCUMSTANCES RELATING TO EXCHANGE ACT FILINGS

I, Lars Nyberg, Chairman of the Board and Chief Executive Officer of NCR
Corporation, state and attest that:

     (1) To the best of my knowledge, based upon a review of the covered reports
     of NCR Corporation, and, except as corrected or supplemented in a
     subsequent covered report:

          . no covered report contained an untrue statement of a material fact
            as of the end of the period covered by such report (or in the case
            of a report on Form 8-K or definitive proxy materials, as of the
            date on which it was filed); and
          . no covered report omitted to state a material fact necessary to make
            the statements in the covered report, in light of the circumstances
            under which they were made, not misleading as of the end of the
            period covered by such report (or in the case of a report on Form
            8-K or definitive proxy materials, as of the date on which it was
            filed).

     (2) I have reviewed the contents of this statement with NCR Corporation's
     Audit and Finance Committee.

     (3) In this statement under oath, each of the following, if filed on or
     before the date of this statement, is a "covered report":

          . Annual Report on Form 10-K for the period ended December 31, 2001 of
            NCR Corporation;
          . all reports on Form 10-Q, all reports on Form 8-K and all definitive
            proxy materials of NCR Corporation filed with the Commission
            subsequent to the filing of the Form 10-K identified above; and
          . any amendments to any of the foregoing.


                            Subscribed and sworn to before me this 13/th/ day of
                                                                  --------
                            August 2002.
                            ------
