Exhibit 99.1

UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION

The following amended unaudited pro forma consolidated
statement of operations was initially included as Exhibit 99.1 to our Annual Report on Form 10-K for the year ended December 31, 2007 and is included in this Form 10-Q, as amended, in order to present certain clerical corrections, which do not
materially change the information previously presented.

The following unaudited pro forma consolidated statement of operations has been developed by
applying pro forma adjustments to the historical audited consolidated financial statements of Nielsen and subsidiaries appearing elsewhere in this prospectus. The unaudited pro forma consolidated statement of operations gives effect to the
Transactions as if they had occurred on January 1, 2006. Assumptions underlying the pro forma adjustments are described in the accompanying notes, which should be read in conjunction with the unaudited pro forma consolidated statement of
operations.

The unaudited pro forma adjustments are based upon available information and certain assumptions that are factually supportable and that we
believe are reasonable under the circumstances. The unaudited pro forma consolidated financial information is presented for informational purposes only. The unaudited pro forma consolidated financial information does not purport to represent what
our actual consolidated results of operations or the consolidated financial condition would have been had the Transactions actually occurred on the dates indicated, nor are they necessarily indicative of future consolidated results of operations or
consolidated financial condition. The unaudited pro forma consolidated statement of operations should be read in conjunction with the information contained Selected Historical Consolidated Financial Data, Managements
Discussion and Analysis of Financial Condition and Results of Operations and the audited consolidated statement of operations and the related notes thereto appearing in the Nielsen Company B.V. Form 10-K for the year ended December 31,
2007. All pro forma adjustments and their underlying assumptions are described more fully in the notes to our unaudited pro forma consolidated statement of operations.
