Hi, I’m Naren Gursahaney, president of ADT Worldwide. About that previous legal text…it’s just our lawyers’ way of saying hello to all of you at Broadview.

Recently I had the pleasure of meeting some of your colleagues based in Texas.  I look forward to meeting more of you after the acquisition is final, but until then, I would like to extend this video greeting to you.

ADT has always held Broadview and its employees in high regard.  We want to add Broadview to the ADT family for its people, processes and expertise, not just the customer accounts.

When the transaction is complete, we will be able to bring aboard your existing expertise and resources as part of our own to broaden our sales, installation and customer service capabilities.

As we all know, the security business is highly fragmented with many thousands of providers in our industry. Also, the vast majority of homes in the U.S. and Canada still do not have monitored security. This represents a significant opportunity for us to grow our business as one company in North America.

Together Broadview and ADT represent an opportunity to expand products and services to both existing and new customers across a broader geographic reach.  Working together we can share best practices and our respective experience and talent, so that our combination of resources can help generate new, high-quality customer relationships in both the residential and commercial markets.

As service companies, Broadview and ADT share a common value: That’s providing the very best service possible to customers. We like the “Customers for Life” culture at Broadview and we think you’ll like the similar approach at ADT.

In fact, Customer Service is one of five core values at ADT that provide a framework for how all our team members work with each other and with our customers and other stakeholders. Along with Customer Service, those values are Integrity, Excellence, Accountability and Teamwork.

At this point, our two companies have recently started the integration planning process. We appreciate your patience and your continued focus on protecting what matters most to our customers.  We expect the integration to go smoothly because Broadview’s business model works well and is consistent with ADT’s, especially our mutual focus on customer service.

We are targeting sometime between April and September of this year to close the transaction and start integrating our respective operations.

All of us at ADT look forward to the time when we can extend an official welcome to all of you at Broadview.   Thank you for your time today and I look forward to meeting as many of you as I can when our companies come together later this year.

(end)
