ITEM 5.           OTHER EVENTS

                  On August 15, 1997 (the "Distribution Date"), Banc One Auto
                  Grantor Trust 1996-B (the "Trust") made a regular monthly
                  distribution of principal and/or interest to holders of the
                  Trust's Class A 6.55% Asset Backed Certificates and Class B
                  6.70% Asset Backed Certificates. The amount of such
                  distribution was based upon the information set forth in the
                  Monthly Statement (the "Original Monthly Statement")
                  reflecting the Trust's activities for the Interest Period from
                  July 15, 1997 through August 14, 1997 (the "Interest Period")
                  and for the Collection Period from July 1, 1997 through July
                  31, 1997 (the "July 1997 Collection Period"). The Original
                  Monthly Statement was delivered to Bankers Trust Company, as
                  trustee (the "Trustee") on or about August 13, 1997.

                  On August 25, 1997, Bank One, Arizona, N.A., as servicer (the
                  "Servicer"), provided notice to the Trustee of the Servicer's
                  discovery of errors in the Original Monthly Statement which
                  affected, among other things, the reported amount of principal
                  and interest collections received by the Trust during the
                  Collection Period and the amounts of principal and interest
                  actually distributed to Certificateholders on the August 1997
                  Distribution Date.

                  Included as Exhibit 99.1 hereto is an amended and restated
                  Monthly Statement (the "Amended Monthly Statement") reflecting
                  the Trust's activities for the Interest Period and for the 
                  July 1997 Collection Period in substitution for the
                  Original Monthly Statement. 

                  Also, on August 25, 1997, the Servicer notified the Trustee of
                  its discovery of errors in each of the Original Monthly
                  Statements beginning with the Original Monthly Statement
                  reflecting the Trust's activities for the Collection Period
                  from June 1, 1996 through June 30, 1996 (the "June 1996
                  Collection Period") and continuing with each successive
                  Original Monthly Statement through and including the Original
                  Monthly Statement reflecting the Trust's activities for the
                  July 1997 Collection Period. Included as Exhibit 99.2 hereto
                  is a month-by-month reconciliation disclosing certain amounts
                  reported on each Original Monthly Statement, the respective
                  amounts as they should have been reported in the Original
                  Monthly Statement (each an "Amended Monthly Statement") and
                  any variance between each Original Monthly Statement and the
                  Amended Monthly Statement for such period.

                  The Servicer and the Trustee are currently in discussions to
                  satisfactorily determine the appropriate manner in which to
                  cause former and present Certificateholders to receive all
                  amounts due and oweing them through the July 1997 Collection
                  Period. Accordingly, based on these discussions, the Servicer
                  proposes to submit a month-by-month reconciliation to the
                  Trustee and the Depository Trust Company on or before
                  September 5, 1997 indicating the applicable amounts of
                  principal and/or interest underpaid in each respective
                  Distribution Date beginning with the September 1996
                  Distribution Date through and including the August 1997
                  Distribution Date. The aggregate amount of the principal
                  and/or interest underpaid in these months, which approximates
                  $1,500,000, will be deposited by the Servicer, from its own
                  funds, into the Collection Account for subsequent distribution
                  by the Depository Trust Company to the holders of record for
                  each respective Distribution Date, on or before the September
                  1997 Distribution Date. For the July 1996 and August 1996
                  Distribution Dates, the Servicer overpaid in the aggregate
                  approximately $121,000 in principal and underpaid
                  approximately $600 in interest. Due to the net cash
                  overpayment to the Trust in these two respective Distribution
                  Dates, the Servicer will waive all claims with respect to the
                  principal amount overpaid.

                  This report on Form 8-K is being filed in accordance with a
                  no-action letter dated August 16, 1995 issued by the staff of
                  the Division of Corporation Finance of the Securities and
                  Exchange Commission to Bank One, Texas, N.A., as originator
                  and servicer of Bank One Auto Trust 1995-A.
