PART I – DISTRIBUTION INFORMATION

Item 1. Distribution and Pool Performance Information.

The information required by Item 1121 of Regulation AB is provided in the report attached hereto as Exhibit 99. This report is the monthly report of Citibank Credit Card Issuance Trust containing information regarding the notes of the Citiseries, the master trust’s assets and the collateral certificate for the due period ending May 25, 2007 and the related payment dates for the notes delivered pursuant to Section 907 of the Indenture.

The issuance trust has issued Class A notes, Class B notes and Class C notes of the Citiseries pursuant to an Indenture between the issuance trust and Deutsche Bank Trust Company Americas, as trustee. Principal payments on Class B notes of the Citiseries are subordinated to payments on Class A notes of that series, and principal payments on Class C notes of the Citiseries are subordinated to payments on Class A and Class B notes of that series.

The issuance trust’s primary asset – and its primary source of funds for the payment of principal of and interest on the notes – is a collateral certificate issued by Citibank Credit Card Master Trust I to the issuance trust. The collateral certificate represents an undivided interest in the assets of the master trust. The master trust assets consist primarily of credit card receivables arising in a portfolio of revolving credit card accounts.

For the definitions or descriptions of certain terms used in the attached report, as well as a description of the allocation and payment priorities and subordination provisions applicable to the notes of the Citiseries, see the Prospectus included in the issuance trust’s Registration Statement on Form S-3 (File No. 333-131355), as amended or supplemented to the date hereof.
