[START]

On February 17, 2010, Ed Arditte, Senior Vice President of Strategy and Investor Relations of Tyco International, and Naren Gursahaney, President of ADT Worldwide, participated in an investor conference call. The following is an excerpt from that call:

Ed Arditte:…as most of you know we announced a few weeks ago an agreement to acquire Broadview Security.  Because that transaction does involve stock, we are currently in review, and as a result if you’d please read the Important Information here, look on this slide which is in your deck, that would be appreciated…

Service is a very important part of the Tyco story, and clearly with the announcement relative to Broadview, it is another important piece of the story.  A big portion of that is recurring contractual revenue, and Naren will show you more about that in a few minutes.  And we have worked hard over the last handful of years to continually strengthen our balance sheet.

Let me just quickly finish with a couple of quick slides on Broadview.  We are somewhat limited in terms of our Q&A on Broadview today, but this slide and the next gives you a quick summary.  I think what’s important here are the third and the fourth bullet points.  We bring in $0.5 billion of additional recurring revenue to the Company on an annualized basis when this transaction closes, and we bring in 1.3 million accounts.  Now, ADT today has about 7.3 million accounts, so it gives you a little bit of perspective of what we’re adding to ADT.

Why do we like it?  It’s a very, very strong fit.  It’s hard to imagine that two businesses that are in the same industry but a large, competitive, fragmented industry, two businesses that do similar things in residential, do similar things in small business, obviously represents a good fit.  We think that there are products and services that we can offer to the broader customer base that will be attractive and will be enhanced service offerings.  There are clearly some very significant synergies on day one, and so even with 70% of the payment for Broadview being in the form of equity, this transaction is very, very nicely accretive in year one, even more so in year two.   When you look at some of the non-cash charges that are involved, it’s even more accretive on a cash earnings basis.  So with that, we think this is a very, very good transaction for our shareholders, a very strong strategic fit, and very, very good financial returns.  So, I’m going to stop there, I’m going to turn it over to Naren, and he will take you through a lot more detail on ADT.  Naren, all yours.

Naren Gursahaney:Thanks Ed, and good afternoon, everybody.  As Ed mentioned, I’m going to give an overview of the ADT Worldwide business but in light of the Broadview acquisition announcement that we made that Ed talked about, I’m going to dig a little bit deeper into our North America residential and small business market than I normally would to just give you a flavor for what that business is, what the real business drivers are, and how we’re performing against those business drivers.

The North America residential/small business market really has a strong business and economic model, and we continue to improve that and refine that.  As we move forward with the Broadview acquisition, we hope that that will even further strengthen our position there.

Unidentified Participant:All right, how about the, how do we think about the ADT margin trajectory here, and what you think the potential is?  I mean, you have Brinks coming in, and that should be a positive, obviously.  Europe, some day, will get to 10%, don’t know when that day is, but. 

And on the flip side, you are benefitting now from commercial being down, which is a favorable mix for you right now.  So, and as you try to, you might try to grow the account base faster which initially could be a negative.  So, how do we think about the margin potential of the segment?

Naren Gursahaney:…As I look forward as to kind of what the head winds are as well as the tail winds, we’ll start with the tail winds.  Clearly the Broadview, we have Brinks security business, will be a tailwind for us and that will be accretive for us from a margin perspective.  Again, their margin rates are comparable to our, to what we see in our resi and small business side.  Once you take out the corporate costs, you know, the costs that they have in order to act as a public company out there.  So operationally, they’re very similar to ours, so our mix does get better there.

Ed Arditte:Let me just elaborate a little bit on the tailwind side for just a minute.  Bringing in Broadview for a full year, in the first full year, will add something in the neighborhood of 50 basis points of margin to ADT on a global basis, and then based on the incremental synergies that we would expect to get in year two, we start to move up to closer to 150 basis points of improvement to ADT overall.

Unidentified Participant:Hi, can you give us any quantitative metrics as far as where you were maybe five years ago, now, and a target for five years out on attrition rates and cost to acquire accounts?

Naren Gursahaney:I think yeah, attrition rates, you know, we’ve kind of gone from the high, I’d say from the high teens down to kind of in the mid-13 range.  Again, we did see a little bit of a pick-up over the past year with the economic environment, but that has stabilized and is starting to improve modestly again.  I’m hesitant to kind of give a five-year out forecast at this point in time.  We don’t really know what the entitlement is.  We’re continuing to work through it, and again the economy does play a role in this thing.  We’ve seen significantly higher attrition in our commercial business, as clearly our commercial customers have been hit harder by the economic environment, but I would expect that we will continue to make steady progress as we’ve done over the past couple years.  I’m optimistic that as we kind of move forward with the Broadview integration, there’s hopefully some things we can learn from them that might even give us more ideas on how we can further improve in that area.
