ITEM 5.        OTHER EVENTS.

         On April 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 ("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 March 15, 1997 through April 14, 1997 (the "March 1997 Interest Period")
and for the Collection Period from March 1, 1997 through March 31, 1997 (the
"March 1997 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 March 1997 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 March 1997 Interest Period and for the March 1997 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 underpayment of $334,130.65 in
principal and an aggregate overpayment of $2,767.74 in interest to
certificateholders on the Distribution Date. The aggregate amount of the
principal 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 March 31, 1997. The Servicer has waived all
claims which it may have with respect to the amount of the overpayment of
interest on the Distribution Date.

amounts due and owing to certificateholders as a result of the errors in such
other monthly statements.
