ITEM 5.  OTHER EVENTS.

         On September 16, 1996, (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 ("Class A Certificates") and Class B 6.70% Asset Backed
Certificates ("Class B Certificates"). The amount of such distribution was based
upon the information set forth in the Determination Date Statement (the
"Original Statement") reflecting the Trust's activities for the Interest Period
from August 15, 1996 through September 14, 1996 (the "August 1996 Interest
Period") and for the Collection Period from August 1, 1996 through August 31,
1996 (the "August 1996 Collection Period"). The Original Statement was delivered
to certificateholders and filed as Exhibit 99.1 to the Trust's Current Report on
Form 8-K.

         On August 25, 1997, Bank One, Arizona, N.A., as servicer (the
"Servicer"), provided notice to Bankers Trust Company, as trustee (the
"Trustee"), of the Servicer's discovery of errors in the Original Statement
which affected, among other things, the reported amount of principal and
interest collections received by the Trust during the August 1996 Collection
Period and the amounts actually distributed to certificateholders on the
Distribution Date.

         This Amendment No. 1 on Form 8-K/A is being filed for the purpose of
filing an amended and restated Determination Date Statement (the "Amended
Monthly Statement") as Exhibit 99.1 hereto reflecting the Trust's activities for
the August 1996 Interest Period and for the August 1996 Collection Period in
substitution for the Original Statement. Exhibit 99.2 hereto includes a
reconciliation showing for certain selected items the amounts reported on the
Original Statement, the amounts reported on the Amended Statement and any
variance between the two amounts.

       The Servicer has  identified  an aggregate  overpayment  of $15,254.39 in
principal   and  an   aggregate   underpayment   of  $662.37  in   interest   to
certificateholders  on  the  Distribution  Date.  The  aggregate  amount  of the
interest underpayment has been deposited by the Servicer,  out of its own funds,
into the Collection  Account for  distribution on or about September 15, 1997 to
certificateholders  of record as of August 31, 1996. The Servicer has waived all
claims  which it may have  with  respect  to the  amount of the  overpayment  of
principal on the Distribution Date.

         The Trust's Current Report on Form 8-K filed August 29, 1997 contains
additional information regarding the Servicer's discovery of errors in other
monthly statements issued by the

                                        2



Trust as well as information regarding the net amounts due and owing to
certificateholders as a result of the errors in such other monthly statements.
