Item 5.           Other Events.

         The  information  provided  below is  provided  in respect of  Citibank
Credit Card Master  Trust I. Certain  capitalized  terms used herein are used as
defined in the Glossary of Terms at the end of this Report.

Loss and Delinquency Experience

         The following tables set forth the loss and delinquency experience with
respect  to  payments  by  cardholders  for each of the  periods  shown  for the
Accounts.  With respect to the Loss Experience  table below,  loss experience is
shown on a cash  basis for  Principal  Receivables.  If accrued  Finance  Charge
Receivables which have been written off were included in losses in the following
table,  Net Losses would be higher as an absolute  number and as a percentage of
the average of Principal and Finance Charge  Receivables  outstanding during the
periods  indicated.  There  can be no  assurance  that the loss and  delinquency
experience  for the  Receivables in the future will be similar to the historical
experience set forth below with respect to the Accounts.

Revenue Experience


         The  revenues  for the  Accounts  from  finance  charges,  fees paid by
cardholders and interchange for the nine months ended September 30, 1997 and for
each year of the three-year  period ended December 31, 1996 are set forth in the
following table.

         The revenue  experience in the  following  table is presented on a cash
basis before deduction for charge-offs.  Revenues from finance charges, fees and
interchange will be affected by numerous factors, including the periodic finance
charge on the receivables,  the amount of any annual  membership fee, other fees
paid by cardholders, the percentage of cardholders who pay off their balances in
full each month and do not incur  periodic  finance  charges on  purchases,  the
percentage of Accounts bearing finance charges at promotional  rates and changes
in the level of delinquencies on the Receivables.

Average Revenue Yield (1)(2)...  18.58%           18.36%      18.11%      18.81%


(1)      Average  Revenue  Yield is the result of dividing  Finance  Charges and
         Fees Paid by  Average  Principal  Receivables  Outstanding  during  the
         periods indicated.
(2)      The percentage for the nine months ended September 30, 1997 is an
         annualized number.


         The revenues  related to periodic  finance charges and fees (other than
annual fees) depend in part upon the collective preference of cardholders to use
their credit cards as revolving debt instruments for purchases and cash advances
and to pay off account  balances over several  months as opposed to  convenience
use (where the  cardholders  prefer instead to pay off their entire balance each
month,  thereby  avoiding  periodic finance charges on purchases) and upon other
services of which the cardholder chooses to avail himself and which are paid for
by the use of the card.  Fees for  these  other  services  will be  treated  for
purposes  of the  Pooling  Agreement  and the  Series  Supplement  as  Principal
Receivables rather than Finance Charge Receivables;  however,  the Banks will be
permitted  to  specify  that any such fees will be  treated  as  Finance  Charge
Receivables.  Revenues  related to periodic finance charges and fees also depend
on the types of charges and fees assessed on the Accounts. Accordingly, revenues
will be affected by future  changes in the types of charges and fees assessed on
the Accounts and in the types of Additional  Accounts the  receivables for which
are added to the Trust from time to time.  Revenues could be adversely  affected
by future changes in fees and charges assessed by CBSD and other factors.

         CBSD  has  previously  reduced  the  finance  charges  and  reduced  or
eliminated  the annual fees  applicable  to, and  modified  some other terms of,
certain of the  Accounts.  These  changes  have  reduced  the gross yield of the
Accounts.

Cardholder Monthly Payment Rates for the Accounts

         Monthly payment rates on the Receivables may vary because,  among other
things,  cardholders may fail to make a required payment, may only make payments
as low as the  minimum  required  payment  or may make  payments  as high as the
entire  outstanding  balance.  Monthly payment rates on the Receivables may also
vary due to seasonal purchasing and payment habits of cardholders. The following
table sets forth the highest and lowest cardholder monthly payment rates for the
Accounts during any month in the periods shown and the average of the cardholder
monthly  payment  rates for all months  during the periods  shown,  in each case
calculated  as a percentage  of the total  beginning  account  balances for such
month.  Monthly payment rates reflected in the table include amounts which would
be deemed payments of Principal  Receivables and Finance Charge Receivables with
respect to the Accounts. In addition, the amount of outstanding  Receivables and
the rates of payments,  delinquencies,  charge-offs  and new  borrowings  on the
Accounts  depend on a variety  of factors  including  seasonal  variations,  the
availability of other sources of credit, general economic conditions,  tax laws,
consumer  spending and borrowing  patterns and the terms of the Accounts  (which
are subject to change by CBSD).

The Receivables

         The  Receivables  in  the  Accounts  as of  October  4,  1997  included
$518,753,587  of Finance Charge  Receivables  and  $34,558,088,911  of Principal
Receivables  (which  amounts  include  overdue  Finance Charge  Receivables  and
overdue  Principal  Receivables).  As of October 4, 1997,  there were 28,330,433
Accounts.


                                        6

<PAGE>


Included  within the Accounts are inactive  Accounts  that have no balance.  The
Accounts had an average  Principal  Receivable  balance of $1,220 and an average
credit limit of $5,090.  The average total Receivable balance in the Accounts as
a percentage  of the average  credit limit with respect to the Accounts was 24%.
Approximately  89%  of  the  Accounts  were  opened  prior  to  September  1995.
Approximately  13.19%,  10.98%,  6.65%  and  5.63% of the  Accounts  related  to
cardholders having billing addresses in California, New York, Texas and Florida,
respectively.  Not more than 5% of the Accounts  related to  cardholders  having
billing addresses in any other single state.

          The periodic  finance charge assessed on balances in most accounts for
cash  advances and  purchases is currently  the Prime Rate (as  published in The
Wall Street  Journal) plus a percentage  ranging from 5.4% to 10.4% for accounts
in good  standing,  and the Prime Rate plus 12.9% for  accounts  which have been
recently,  or currently are,  delinquent.  As of the most recent quarterly reset
date, the periodic finance charge ranged from 13.90% to 18.90% for most accounts
in good standing,  and was 21.40% for most accounts which have been recently, or
currently  are,  delinquent.  CBSD may change  the  periodic  finance  charge on
accounts  at any  time by  written  notice  to the  cardholders.  Any  announced
increase in such rate will become  effective  upon the earlier of subsequent use
of a card and the  expiration  of a 25-day  period from the date such change was
made effective  (assuming failure on the part of the cardholder to object to the
new rate). CBSD also offers promotional rates of limited duration to attract new
cardholders and to promote balance transfers from other credit card issuers and,
under certain circumstances,  the periodic finance charge on a limited number of
accounts may be greater or less than those assessed by CBSD generally.

         The Accounts  consist of Eligible  Accounts.  The Banks may (subject to
certain  limitations and  conditions),  and, in certain  circumstances,  will be
obligated to,  designate from time to time Additional  Accounts and to convey to
the Trust all Receivables of such Additional Accounts,  whether such Receivables
are then existing or thereafter created.  The Banks have made Lump Sum Additions
to the Trust which, in the aggregate,  included  approximately $22.42 billion of
Principal Receivables.

         The following  tables  summarize the Accounts by various criteria as of
October 4, 1997. References to "Receivables Outstanding" in the following tables
include both Finance Charge Receivables and Principal  Receivables.  Because the
composition  of the  Accounts  will change in the future,  these  tables are not
necessarily indicative of the future composition of the Accounts.

Loss and Delinquency Experience

         The following tables set forth the loss and delinquency experience with
respect  to  payments  by  cardholders  for each of the  periods  shown  for the
Accounts.  With respect to the Loss Experience  table below,  loss experience is
shown on a cash  basis for  Principal  Receivables.  If accrued  Finance  Charge
Receivables which have been written off were included in losses in the following
table,  Net Losses would be higher as an absolute  number and as a percentage of
the average of Principal and Finance Charge  Receivables  outstanding during the
periods  indicated.  There  can be no  assurance  that the loss and  delinquency
experience  for the  Receivables in the future will be similar to the historical
experience set forth below with respect to the Accounts.

Revenue Experience

         The  revenues  for the  Accounts  from  finance  charges,  fees paid by
cardholders and interchange for the nine months ended September 30, 1997 and for
each year of the three-year  period ended December 31, 1996 are set forth in the
following table.

         The revenue  experience in the  following  table is presented on a cash
basis before deduction for charge-offs.  Revenues from finance charges, fees and
interchange will be affected by numerous factors, including the periodic finance
charge on the receivables,  the amount of any annual  membership fee, other fees
paid by cardholders, the percentage of cardholders who pay off their balances in
full each month and do not incur  periodic  finance  charges on  purchases,  the
percentage of Accounts bearing finance charges at promotional  rates and changes
in the level of delinquencies on the Receivables.

Average Revenue Yield (1)(2)...  18.58%           18.36%      18.11%      18.81%

(1)      Average  Revenue  Yield is the result of dividing  Finance  Charges and
         Fees Paid by  Average  Principal  Receivables  Outstanding  during  the
         periods indicated.
(2)      The percentage for the nine months ended September 30, 1997 is an
         annualized number.

         The revenues  related to periodic  finance charges and fees (other than
annual fees) depend in part upon the collective preference of cardholders to use
their credit cards as revolving debt instruments for purchases and cash advances
and to pay off account  balances over several  months as opposed to  convenience
use (where the  cardholders  prefer instead to pay off their entire balance each
month,  thereby  avoiding  periodic finance charges on purchases) and upon other
services of which the cardholder chooses to avail himself and which are paid for
by the use of the card.  Fees for  these  other  services  will be  treated  for
purposes  of the  Pooling  Agreement  and the  Series  Supplement  as  Principal
Receivables rather than Finance Charge Receivables;  however,  the Banks will be
permitted  to  specify  that any such fees will be  treated  as  Finance  Charge
Receivables.  Revenues  related to periodic finance charges and fees also depend
on the types of charges and fees assessed on the Accounts. Accordingly, revenues
will be affected by future  changes in the types of charges and fees assessed on
the Accounts and in the types of Additional  Accounts the  receivables for which
are added to the Trust from time to time.  Revenues could be adversely  affected
by future changes in fees and charges assessed by CBSD and other factors.

         CBSD  has  previously  reduced  the  finance  charges  and  reduced  or
eliminated  the annual fees  applicable  to, and  modified  some other terms of,
certain of the  Accounts.  These  changes  have  reduced  the gross yield of the
Accounts.

                                        5
Cardholder Monthly Payment Rates for the Accounts

         Monthly payment rates on the Receivables may vary because,  among other
things,  cardholders may fail to make a required payment, may only make payments
as low as the  minimum  required  payment  or may make  payments  as high as the
entire  outstanding  balance.  Monthly payment rates on the Receivables may also
vary due to seasonal purchasing and payment habits of cardholders. The following
table sets forth the highest and lowest cardholder monthly payment rates for the
Accounts during any month in the periods shown and the average of the cardholder
monthly  payment  rates for all months  during the periods  shown,  in each case
calculated  as a percentage  of the total  beginning  account  balances for such
month.  Monthly payment rates reflected in the table include amounts which would
be deemed payments of Principal  Receivables and Finance Charge Receivables with
respect to the Accounts. In addition, the amount of outstanding  Receivables and
the rates of payments,  delinquencies,  charge-offs  and new  borrowings  on the
Accounts  depend on a variety  of factors  including  seasonal  variations,  the
availability of other sources of credit, general economic conditions,  tax laws,
consumer  spending and borrowing  patterns and the terms of the Accounts  (which
are subject to change by CBSD).

The Receivables

         The  Receivables  in  the  Accounts  as of  October  4,  1997  included
$518,753,587  of Finance Charge  Receivables  and  $34,558,088,911  of Principal
Receivables  (which  amounts  include  overdue  Finance Charge  Receivables  and
overdue  Principal  Receivables).  As of October 4, 1997,  there were 28,330,433
Accounts.

                                        6
Included  within the Accounts are inactive  Accounts  that have no balance.  The
Accounts had an average  Principal  Receivable  balance of $1,220 and an average
credit limit of $5,090.  The average total Receivable balance in the Accounts as
a percentage  of the average  credit limit with respect to the Accounts was 24%.
Approximately  89%  of  the  Accounts  were  opened  prior  to  September  1995.
Approximately  13.19%,  10.98%,  6.65%  and  5.63% of the  Accounts  related  to
cardholders having billing addresses in California, New York, Texas and Florida,
respectively.  Not more than 5% of the Accounts  related to  cardholders  having
billing addresses in any other single state.

          The periodic  finance charge assessed on balances in most accounts for
cash  advances and  purchases is currently  the Prime Rate (as  published in The
Wall Street  Journal) plus a percentage  ranging from 5.4% to 10.4% for accounts
in good  standing,  and the Prime Rate plus 12.9% for  accounts  which have been
recently,  or currently are,  delinquent.  As of the most recent quarterly reset
date, the periodic finance charge ranged from 13.90% to 18.90% for most accounts
in good standing,  and was 21.40% for most accounts which have been recently, or
currently  are,  delinquent.  CBSD may change  the  periodic  finance  charge on
accounts  at any  time by  written  notice  to the  cardholders.  Any  announced
increase in such rate will become  effective  upon the earlier of subsequent use
of a card and the  expiration  of a 25-day  period from the date such change was
made effective  (assuming failure on the part of the cardholder to object to the
new rate). CBSD also offers promotional rates of limited duration to attract new
cardholders and to promote balance transfers from other credit card issuers and,
under certain circumstances,  the periodic finance charge on a limited number of
accounts may be greater or less than those assessed by CBSD generally.

         The Accounts  consist of Eligible  Accounts.  The Banks may (subject to
certain  limitations and  conditions),  and, in certain  circumstances,  will be
obligated to,  designate from time to time Additional  Accounts and to convey to
the Trust all Receivables of such Additional Accounts,  whether such Receivables
are then existing or thereafter created.  The Banks have made Lump Sum Additions
to the Trust which, in the aggregate,  included  approximately $22.42 billion of
Principal Receivables.

                                        7
The following  tables  summarize the Accounts by various criteria as of
October 4, 1997. References to "Receivables Outstanding" in the following tables
include both Finance Charge Receivables and Principal  Receivables.  Because the
composition  of the  Accounts  will change in the future,  these  tables are not
necessarily indicative of the future composition of the Accounts.
