Monday, September 28 was a historic day for ACS. Xerox and ACS decided to join forces to create a new class of solutions provider with leading technology and expertise in document and business process management. Together with Xerox, ACS will be able to grow and scale in incredible ways. By leveraging Xerox’s industry-leading document management, strong brand awareness, global account management, and R&D investments, we will be able to offer comprehensive document management, create new automated and differentiated BPO services, acquire new capabilities to sell across both companies’ customer bases, and accelerate ACS’ global infrastructure initiatives in ITO. I am truly excited at the possibilities before us. Xerox understands that ACS’ success is due to your talent and hard work, and they have made it clear that they intend to preserve our vibrant team culture. ACS will continue to operate as an independent organization and maintain our headquarters in Dallas as well as our operations around the world. This will ensure a smooth transition of our internal operations and will appear seamless to our clients. I realize that you will have many questions and concerns, and I want to address them i n the upcoming days. We h ave created this webpage http://www.acs-inc.com/acsquestions for you to learn more about Xerox and read my updates. Feel free to write to acsquestions@acs-inc.com with any question you have. Thank you for your continued hard work. I look forward to many more years of growth and success, in our new path forward.
