In connection with the Acquisition (as defined below), The Western Union Company (the “Company”) is holding a public conference call and webcast today at 9:00 a.m. Eastern Time, during which the Company will provide the presentation attached hereto as Exhibit 99.1. Information regarding access to the conference call and webcast is set forth in the press release attached hereto as Exhibit 99.2. The information furnished under this Item 7.01, including Exhibit 99.1 attached hereto, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, except as shall be expressly set forth by specific reference to such filing.

Today, the Company entered into an agreement (the “Purchase Agreement”) with Travelex Limited, Travelex Currency Services, Inc., Travelex Holdings Limited and Travelex Canada Limited (collectively, the “Sellers”) to acquire (the “Acquisition”) the global business payments business (the “GBP Business”) of the Sellers and their affiliates (the “Travelex Group”). Also today, the Company issued a press release announcing its entry into the Purchase Agreement. A copy of the press release is attached as Exhibit 99.2 and is incorporated herein by reference.

The purchase price for the Acquisition is £606 million subject to adjustment to reflect a debt free cash free sale and to take into account any difference between actual and targeted working capital at closing. The closing of the Acquisition is subject to the satisfaction or waiver of certain customary closing conditions, including: obtaining anti-trust clearances or waivers in certain jurisdictions (including Australia, the United Kingdom and the United States); obtaining certain financial services and other regulatory approvals and consents; and the completion by the Travelex Group of a pre-sale reorganization to separate the GBP Business from other business operations of the Travelex Group. The Acquisition is expected to close in late 2011.

In connection with the Acquisition, the Purchaser and certain of its affiliates will also enter into certain transition services, commercial services and licensing agreements and arrangements in relation to the operation of the GBP Business after closing.
