ITEM 5.  OTHER EVENTS.

         The following information relates to the credit card receivables owned
by Citibank Credit Card Master Trust I and the related credit card accounts.
Some of the terms used below are used as defined in the Glossary of Terms at the
end of this Report.

LOSS AND DELINQUENCY EXPERIENCE

         The following table sets forth the loss experience for cardholder
payments on the credit card accounts for each of the periods shown. Losses
consist of write-offs of principal receivables. These losses are presented below
on a cash basis. If accrued finance charge receivables that have been written
off were included in losses, 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. Average Principal Receivables
Outstanding is the average of principal receivables outstanding during the
periods indicated. The percentage reflected for the three months ended March 31,
2001 is an annualized number. There can be no assurance that the loss experience
for the receivables in the future will be similar to the historical experience
set forth below.

   Receivables Outstanding..       3.83%        3.71%        4.71%        5.89%


         Net losses as a percentage of gross charge-offs for the first three
months of 2001 were 88.92% and for each of the years ended December 31, 2000,
1999 and 1998 were 87.65%, 89.80% and 91.56%, respectively. Gross charge-offs
are charge-offs before recoveries and do not include the amount of any
reductions in Average Principal Receivables Outstanding due to fraud, returned
goods, customer disputes or various other miscellaneous write-offs.

         The following table sets forth the delinquency experience for
cardholder payments on the credit card accounts for each of the periods shown.
The Delinquent Amount includes both principal receivables and finance charge
receivables. The percentages are the result of dividing the Delinquent Amount by
the average of principal and finance charge receivables outstanding during the
periods indicated. There can be no assurance that the delinquency experience for
the receivables in the future will be similar to the historical experience set
forth below.

REVENUE EXPERIENCE

         The revenues for the credit card accounts from finance charges, fees
paid by cardholders and interchange for the three months ended March 31, 2001
and for each year of the three-year period ended December 31, 2000 are set forth
in the following table.

         The revenue experience in this table is presented on a cash basis
before deduction for charge-offs. Average Revenue Yield is the result of
dividing Finance Charges and Fees Paid by Average Principal Receivables
Outstanding during the periods indicated. The percentage for the three months
ended March 31, 2001 is an annualized number. Revenues from finance charges,
fees and interchange will be affected by numerous factors, including the
periodic finance charge on the credit card 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 credit card accounts bearing finance
charges at promotional rates and changes in the level of delinquencies on the
receivables.

                       Revenue Experience for the Accounts
                             (Dollars in Thousands)


                        Three Months          Year Ended December 31,
                           Ended
                       March 31, 2001     2000          1999          1998

   and Fees Paid.......  $2,260,202    $8,096,143    $7,430,599    $6,768,295
Average Revenue Yield .    17.24%        16.64%        17.43%        18.66%


         The revenues from 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 account balances over several months -- as opposed to
convenience use, where cardholders pay off their entire balance each month,
thereby avoiding periodic finance charges on their purchases -- and upon other
card-related


                                       4


<PAGE>

services for which the cardholder pays a fee. Fees for these other services will
be treated for purposes of the pooling and servicing agreement as principal
receivables rather than finance charge receivables; however, the Banks may
specify that they will treat these fees as finance charge receivables. Revenues
from periodic finance charges and fees also depend on the types of charges and
fees assessed on the credit card 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 added from time to time. These
revenues could be adversely affected by future changes in fees and charges
assessed by Citibank (South Dakota) and other factors.

CARDHOLDER MONTHLY PAYMENT RATES

         Monthly payment rates on the credit card receivables may vary because,
among other things, a cardholder may fail to make a required payment, may only
make the minimum required payment or may pay 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 credit card 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 that month. Monthly
payment rates include amounts that 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 Citibank (South Dakota)
may change.

INTERCHANGE

         Creditors participating in the MasterCard International and VISA
associations receive interchange as partial compensation for taking credit risk,
absorbing fraud losses and funding receivables for a limited period before
initial billing. Under the MasterCard International and VISA systems, a portion
of this interchange in connection with cardholder charges for merchandise and
services is passed from banks which clear the transactions for merchants to
credit card-issuing banks. Interchange ranges from approximately 1% to 2% of the
transaction amount. Citibank (South Dakota) is required to transfer to the
master trust interchange attributed


                                       5


<PAGE>

to cardholder charges for merchandise and services in the accounts. Interchange
is allocated to the master trust on the basis of the ratio that the amount of
cardholder charges for merchandise and services in the accounts bears to the
total amount of cardholder charges for merchandise and services in the portfolio
of credit card accounts owned by Citibank (South Dakota). MasterCard
International and VISA may change the amount of interchange reimbursed to banks
issuing their credit cards.

THE CREDIT CARD RECEIVABLES

         The receivables in the credit card accounts as of March 31, 2001
included $723,441,486 of finance charge receivables and $52,020,993,376 of
principal receivables -- which amounts include overdue finance charge
receivables and overdue principal receivables. As of March 31, 2001, there were
40,849,284 accounts. Included within the accounts are inactive accounts that
have no balance. The accounts had an average principal receivable balance of
$1,273 and an average credit limit of $6,129. The average total receivable
balance in the accounts as a percentage of the average credit limit with respect
to the accounts was 21%. Approximately 83% of the accounts were opened before
March 1999. Of the accounts, approximately 13.56% related to cardholders with
billing addresses in California, 10.31% in New York, 6.70% in Texas and 5.83% in
Florida. Not more than 5% of the accounts related to cardholders having billing
addresses in any other single state.

         The credit card accounts include receivables which, in accordance with
the servicer's normal servicing policies, were charged-off as uncollectible
before they were added to the master trust. However, for purposes of calculation
of the amount of principal receivables and finance charge receivables in the
master trust for any date, the balance of the charged-off receivables is zero
and the master trust owns only the right to receive recoveries on these
receivables.

         The following tables summarize the credit card accounts by various
criteria as of March 31, 2001. References to "Receivables Outstanding" in these
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.

         Credit balances presented in the following table are a result of
cardholder payments and credit adjustments applied in excess of a credit card
account's unpaid balance. Accounts which have a credit balance are included
because receivables may be generated in these accounts in the future. Credit
card accounts which have no balance are included because receivables may be
generated in these accounts in the future.

BILLING AND PAYMENTS

         The credit card accounts have different billing and payment structures,
including different periodic finance charges and fees. The following information
reflects the current billing and payment characteristics of the accounts.


                                       8

         Citibank (South Dakota) sends monthly billing statements to cardholders
with balances at the end of each billing period. Each month a MasterCard or VISA
cardholder must make a minimum payment equal to the sum of

                  (1) the greater of $20 -- or, if the then current balance is
                      less than $20, that balance -- and 1/48 of the then
                      current balance,

                  (2) any amount which is past due and

                  (3) any amount which is in excess of the credit limit.

         The required minimum payment, however, cannot be less than the finance
charges billed.

         A periodic finance charge is assessed on the credit card accounts. The
periodic finance charge assessed on balances for purchases and cash advances for
a majority of the accounts is calculated by multiplying (1) the daily balances
for each day during the billing cycle by (2) the applicable daily periodic
finance charge rate, and summing the results for each day in the billing period.
The daily balance is calculated by taking the previous day's balance, adding any
new purchases or cash advances and fees, adding the daily finance charge on the
previous day's balance, and subtracting any payments or credits. Cash advances
are included in the daily balance from the date the advances are made. Purchases
are included in the daily balance generally from the date of purchase. Periodic
finance charges are not assessed in most circumstances on purchase amounts if
all balances shown in the previous billing statement are paid in full by the due
date indicated on the statement.

         The periodic finance charge assessed on balances in most credit card
accounts for purchases is currently the Prime Rate, as published in The Wall
Street Journal, plus a percentage ranging from 5.40% to 14.99%. As of the most
recent monthly reset date, the periodic finance charge on balances in most
accounts for purchases ranged from 12.90% to 22.49%. The periodic finance charge
assessed on balances in most credit card accounts for cash advances is currently
19.99%. Citibank (South Dakota) may change the periodic finance charge on
accounts at any time by written notice to cardholders.

         Any increase in the finance charge will become effective upon the
earlier of subsequent use of a card and the expiration of a 25-day period from
the date the change was made effective -- assuming failure on the part of the
cardholder to object to the new rate. Citibank (South Dakota) also offers
promotional rates of limited duration to attract new cardholders and to promote
balance transfers from other credit card issuers and the periodic finance charge
on a limited number of accounts may be greater or less than those assessed by
Citibank (South Dakota) generally.

Some of the accounts may be subject to additional fees, including:

  o  a late fee of $29 if Citibank (South Dakota) does not receive a required
     minimum payment by the payment date shown on the monthly billing statement,
     which fee is assessed monthly until the account is less than 30 days past
     due;


                                       9


<PAGE>

  o  a cash advance fee which is generally equal to 3.0% of the amount of the
     cash advance, subject to a minimum fee of $5;

  o  a balance transfer fee of 3.0% of the amount transferred to the account,
     subject to a minimum fee of $5 and a maximum fee of $29;

  o  a returned payment fee of $29;

  o  a returned check fee of $29;

  o  a stop payment fee of $29; and

  o  a fee of $29 for each billing period with respect to each account with an
     outstanding balance over the credit limit established for that account.

         Payments by cardholders on the accounts are processed and applied to
all minimum amounts due, from the oldest to the most current, with respect to
the following items in the following order:

         (1) periodic finance charges on cash advances,
         (2) periodic finance charges on purchases,
         (3) cash advance amounts and
         (4) purchase amounts.

         When all minimum amounts due are paid, payments are generally allocated
first to cash advance balances and then to purchase balances. There can be no
assurance that periodic finance charges, fees and other charges will remain at
current levels in the future.
