** On September 12, 2008 Citibank Credit Card Master Trust I issued Series
2008-C1, consisting of $500,000,000 Floating Rate Class A Credit
Card Participation Certificates and $32,000,000 Floating Rate Class B
Credit Card Participation Certificates. By increasing the amount
of floating rate certificates issued out of the Master Trust, the
Weighted Average Certificate Rate for the following Due Period is
expected to decrease from the level reported in this Servicer's Report.
(1) Values for "Current Due Period on an Actual Basis" reflect,
in the case of a first due period close of a series, activity
from the close date until the first due period end, or, as in
the case of Investor Monthly Interest and certain fees, until
the first distribution date. Values for "Current Due Period on
a Standard Basis" reflect activity for the entire current
period, as if all series had already been outstanding prior to
the first day of such period.
All percents are based on actual cash revenue or expense for
the period, converted to an annualized percent using day count
appropriate for the item, either 30/360, actual/360, or actual/actual.
Depending on the item, cash expenses may accrue
from July 29, 2008 to August 26, 2008, 29 days, or
August 4 , 2008 to September 1 , 2008, 29 days (standard basis).
