Jay Brown - CFO
Thank you Fiona, and good morning everyone. Let me start with a few summary comments as highlighted on page three of the presentation and then I will go through our results and outlook in greater detail. I am very pleased with our second quarter financial results as we significantly exceeded our expectations per adjusted EBITDA, reflecting the increased demand for wireless infrastructure, as evidenced by the 9% increase in rental site revenues from the second quarter of last year.
In addition to a great quarter in site rental revenue, our services business also performed very well. Service revenues were up 39% and service gross margins were up 33% compared to the same quarter of last year. In addition, I believe the investments we made, including the purchase of our common shares, the acquisition of land beneath our towers and our agreement to acquire NewPath, will enhance long-term recurring cash flow per share growth.
The acquisition of NewPath is expected to extend our ability to provide wireless infrastructure to our customers beyond those areas served by traditional towers and will increase our presence in this market to 44 DAS networks in operation or under construction. The combination of strong year-to-date revenue growth and our expectations for the second half of 2010 allows us to increase our site rental revenue, site rental gross margin, adjusted EBITDA and recurring cash flow outlook for the full-year 2010. With that I would like to take you through the results in greater detail for the quarter and the increase in our 2010 outlook.
Turning to slide four, during the second quarter we generated site rental revenue of $410 million, up 9% from the second quarter of 2009. Similar to what we would expect in the balance of the year, the components of the 9% growth and site rental revenue from the second quarter 2009 to the second quarter 2010, were comprised of the following; 4% growth in the existing base of business through contracted escalators and the renewal of tenant leases, net of any [churn] and 5% growth attributable to the additional tenant equipment added to our site reflecting the new leasing activity we have experienced.
Site rental gross margin defined as site rental revenues less the cost of operations was $294 million, up 12% from the second quarter of 2009. We continue to maintain a disciplined approach to operating costs, resulting in over 94% of the growth and site rental revenue finding its way to site rental gross margin.
Adjusted EBITDA for the second quarter of 2010 was $280 million, up 13% from the second quarter of 2009. It is important to note that these growth rates were achieved almost entirely through organic growth on assets that we owned as of April 1, 2009, as revenue growth from acquisitions was negligible.
Turning to slide five, recurring cash flow defined as adjusted EBITDA, less interest expense, less sustaining capital expenditures, increased 18% to $155 million compared to $132 million in the second quarter of 2009. Recurring cash flow per share also increased 18% to $0.54, compared to $0.46 in the second quarter of 2009.
Moving to the outlook for the third quarter of 2010 as shown on slide six, we expect site rental revenue of between $419 million and $424 million and adjusted EBITDA between $284 million and $289 million.
The sequential growth in adjusted EBITDA between the second quarter 2010 and our outlook for the third quarter of 2010 is impacted by the following couple of items. We expect third quarter repairs and maintenance as a component of site rental operating expenses to increase by approximately $2 million from the second quarter of this year. And commensurate with the increase in operating expenses related to repairs and maintenance, we would expect sustaining capital expenditures to also be approximately $2 million higher in the third quarter than in the previous two quarters of the year.
Turning to the full-year 2010 outlook on slide seven, based on the strong results today and our expectations for the remainder of the year, we have increased the mid-point of our outlook by site rental revenues by $4.5 million, site rental growth margin by $7 million, adjusted EBITDA by $15.5 million and recurring cash flow by $20.5 million for the full year of 2010.
Our revised 2010 outlook suggests annual site rental revenue growth of just over 8% and recurring cash flow growth of 17% respectively. Substantially all of the anticipated growth is expected to come from the assets we owned at the beginning of 2008. As I mentioned before, we have made no significant tower acquisitions the last two years. Consistent with our past practice, our 2010 outlook doesn't include the anticipated benefit from expected future investment around our core business and we have not included NewPath in our outlook.
Turning to the balance sheet as illustrated on slide eight, total debts to last quarter annualized adjusted EBITDA as of June 30, 2010, was 5.6 times compared to 6.1 times in the same quarter of last year. Adjusted EBITDA to cash interest expense as of June 30, 2010, was approximately 2.8 times. Both our adjusted EBITDA leverage and cash interest expense coverage ratio were comfortably within their respective debt covenant requirements.
As illustrated on slide nine, the liability on a settlement basis associated with our [forward starting] interest rate swaps due to be settled during 2011, was 700 -- $372 million at June 30, 2010. As shown, we have also provided the sensitivity for these swaps to changes in interest rate.
Moving on to the investments and liquidity, the table on slide ten reflects our current debt balances and maturities. As many of you have seen, yesterday we launched a $1.55 billion offering to repay in full the $1.33 billion of series 2006-1 notes outstanding which have an anticipated refinancing date of November 15, 2011. Assuming the successful completion of this financing, we will have no maturities before March 2014.
Further, during the last six quarters, we will have refinanced over $6 billion of debt securities with an appropriately -- an appropriate laddering of the maturity. This gives us tremendous flexibility as we focus on investing activities that we believe will enhance long-term recurring cash flow per share, which we believe is the best long-term measure of shareholder value creation.
To that end, as shown on slide eleven, during the second quarter of 2010, we spent 30 -- just over $38 million to purchase our common shares with an average price of over $37 per share. Since January 2003, we have spent $2.4 billion buying back 92 million shares or potential shares at an average per-share price of $25.59. Without these purchases, our current share count would be nearly a third higher than what it is today.
Also, during the second quarter of 2010, we spent $55 million on capital expenditures, including $31 million on land purchases, as we accelerated our spending on our land lease purchase program. Since the beginning of 2010, we have extended 620 land leases and purchased the land beneath 193 of our towers. We have had significant success with this program over the last several years. In fact, today, 33% of our site rental gross margin is generated on towers -- from towers on land that we own.
As of today, we owner control for more than 20 years the land beneath towers representing approximately 69% of our gross margin. Further, the average term remaining on our ground leases is approximately 31 years. Having completed over 8,600 transactions, we believe that this activity has resulted in the most secured land position in the industry based on land ownership and the final ground lease expiration. We continue to believe this is an important long-term effort that provides a long-term benefit as it protects our margins and controls our largest operating expense.
In summary, I had a great -- we had a great quarter and I'm excited about the balance of 2010. I am pleased we were back to allocating capital in areas related to our core tower business to enhance long-term growth rates and recurring cash flow per share. And with that, I will turn the call over to Ben.
Ben Moreland - CEO
Thanks, Jay. Thanks to all of you for joining us on the call this morning. As Jay just mentioned, we had a strong second quarter exceeding our outlook for site rental gross margin, adjusted EBITDA and recurring cash flow. In addition to continued growth of our site leasing business, our services business continues to perform very well, posting the highest quarterly results in recent years, due to the increase take rate delivering on the part of our customers. This success results from a diligent effort to capture more of the opportunities assisting our customers in locating or upgrading installations on our site.
We have also benefited from an expanded range of service offerings over the past couple of years. This increase in services activity is attributable to the confidence our customers have in Crown Castle as regularly expressed in our customer surveys that consistently rank us as delivering the highest customer service in the industry. This did not just happen by accident. I want to thank our employees who were involved in this effort for this tremendous result this quarter and for the year.
While the services business is somewhat difficult to predict, it's evolved into a more stable contributor to our core leasing business over the last two years. Moving past the summary for the quarter, I would like to draw your attention to some of the important trends that are driving our business. The trends underlying our business remain very positive with the adoption of the mobile internet and demand for data services driving our strong growth and operating results. As wireless data services become the carrier's most important growth segment, the carriers are leasing more of our site to support the growth and demand for wireless data services to capture the higher average revenue per user or R2.
Data revenue growth continues to be driven by customer demand and interest in the smartphone category and by the proliferation of new devices with greater capabilities together with significant increases in innovative applications and content. These overwhelming trends were reflected in the carrier's second quarter results which she not only growing data usage but importantly, confirm the fact that these investments in network improvements are profitable.
The iPhone has helped drive robust wireless data growth and ARPU improvements at AT&T. Specifically more than 3.2 million iPhones were activated on the AT&T network in the quarter. AT&T also reported very positive customer response to the iPad 3G which launched at the end of April and attributed the introduction of the iPad to 300,000 prepaid ads. A little more than half of AT&T's post-paid subscribers now have integrated devices and the ARPU from integrated -- for integrated devices continues to be 1.7 times greater than the ARPU for non-integrated devices. This data growth contributed to a 27% increase in wireless data revenues at AT&T versus the second quarter of 2009, and data and increasing percentage of the carrier's overall revenue represented 31% of the AT&T's second quarter wireless service revenues, up from 26% a year ago.
Similarly Verizon reported data revenue growth of 24% compared to last year and total data ARPU growth of 16% year-over-year driven by the rapidly-growing smartphone device category. At the end of the second quarter, 35% of Verizon's retail post-paid subscriber base had smartphones or multimedia devices, up from 26% just two quarters ago. In addition, both AT&T and Verizon reported adding significant numbers of other connected machine-to-machine devices, such as e-readers, alarm-monitoring systems, vehicle-tracking devices, consumer electronics, smart grid solutions and medical alert devices and a host of other emerging products.
While these trends are very compelling, it's important to note that the adoption is still in the early stages, with less than 40% of wireless subscribers having a data-centric device, representing considerable upside to come. Furthermore, the carriers are in the early phases of building out high-speed data networks. With Clearwire, for example, only halfway through its planned 40,000 site build and Verizon still on schedule to launch 4G in the fourth quarter and selected markets. We believe our increased 2010 outlook, which includes increased leasing activity in the second half of the year, reflects the launch and prelaunch activities of these coming 4G services and is consistent with the wireless carrier's recent comments on their expectations for somewhat back-end loaded year reflecting the launch of LTE.
I should note that the devices alone are not the only ingredient to success. Network quality remains a key factor in the acquisition and retention of subscribers, resulting in carriers investing in their networks to ensure coverage and capacity to meet customer needs in order to remain competitive. To that end, both AT&T and Verizon reported significant increases in wireless capital expenditures in the first half of 2010, compared to the first half of 2009, driven by data capacity enhancements and 4G LTE network deployments.
Confirming the view that demand for wireless services will extend beyond just the legacy networks, we're very excited to see the announcement from Harbinger Capital Partners around their intention to build a wholesale 4G wireless network via a company called Light Squared.
As recently announced, Light Squared expects their network to require 40,000 cell sites over the next five years. As the largest owner of sites in the top 100 market, Crown Castle looks forward to being a material participant in assisting Light Squared in accomplishing their ambitious deployment plans. This build-out is similar in scale to Clearwire's proposed network plan, which as noted earlier is approaching 50% completion and still proceeding very well. These new 4G network deployments, which are responsive to the mobile internet demand we're witnessing, along with the ongoing activity from the incumbent carriers, add confidence to our long-term growth prospects.
As demand for data services continues unabated, network architecture is evolving. Increasingly, we believe that distributing antenna systems will be an important compliment to traditional tower installing. As such, we're excited to have entered into a agreement to acquire NewPath Networks which we expect to close later this quarter. The acquisition of NewPath furthers our capabilities in DAS, enabling us to provide more wireless infrastructure for customers beyond those areas served by traditional towers and augmenting our service offering in this growing market.
Like the tower business, the DAS business is a shared infrastructure model and is an important element of the network architecture going forward, as carriers work to satisfy coverage and capacity challenges that have become more acute with the growing -- with the growth and dependency on data services we all have come to expect. NewPath is a leading provider of DAS networks with a strong reputation and demonstrated leadership in the market, and we look forward to them joining the Crown team.
Similar to our existing customer base, NewPath has a high concentration of revenues from the leading wireless carriers, with 75% of the revenues coming from the top four wireless carriers. Following the acquisition of NewPath, we will have 44 DAS networks in operation or under construction. Based on existing and contracted networks under construction, we expect the acquisition of NewPath to be short and long-term accretive to our financial results.
So to wrap up, I would like to reiterate a couple of few points we have made this morning. We're obviously very pleased with our results and believe they demonstrate the quality of our assets combined with our ability to execute for customers. As always, we remain disciplined and focused on maximizing long-term recurring cash flow per share through opportunistic investments. These investments can take the form of share purchases, land purchases, tower acquisitions and, obviously now, DAS networks. Lastly at a macro level, we were very excited about the trends we were seeing in wireless and our position to capture value from them. We have the most towers in the top 100 US markets and the highest level of customer service. We are focused on the US market where the ability of the wireless carriers to make profitable investments is most apparent and barriers to entry remain high. We've had a great first half of the year and we expect an even better second half, as reflected in our increase in outlook for the balance of 2010. With that Operator, I'd be pleased to turn the call over for questions.
Operator
Thank you sir. (Operator Instructions) Our first question comes from the line of Brett Feldman with Deutsche Bank. Please go ahead.
Brett Feldman - Analyst
Thanks for taking the question and thanks for all the color there. I was hoping to talk more about the outlook for your second half of the year. You obviously are expecting an increase in leasing activity. Is there any way we can quantify that, for example, is there anything that you can say about your backlog or the pace of commence leases to help us get a better understanding of what is really behind that improved revenue of guidance?
Jay Brown - CFO
Sure, Brett. Happy to take that question. As we look at the first half of year, I think we talked on the prior calls that we thought the year was going to be sort of 40/60. It looks like it's probably going to be closer to 0.3, 0.6, so about 0.6 of the activity we would expect for the full year will be in the second half. And I think Ben's comments around what we're seeing with both LTE and 4G launches are really driving a lot of that activity.
The carriers made a lot of comments, obviously in the first quarter call, about what they were spending their capital on in the first half of the year. A lot of those things, be it back haul, fiber back haul and a few other things they mentioned, really don't necessarily drive a lot of necessary leasing activity on our assets. And what we're expect -- what we're both seeing and expecting would suggest a pickup in the activity that we saw in the first half going into the second half of the year.
Brett Feldman - Analyst
And based on the type of projects you just talked about, is this mostly amendment-related or are you seeing an increase in new full-site deployments?
Ben Moreland - CEO
It's both, Brett. This is Ben. We're seeing obviously a lot of amendments as we have talked about on prior calls. There has been a mixed shift in the business gradually over the last two years where we're seeing a lot of amendment activity around data upgrades, whether it be 3G, legacy network or 4G LTE applications. So the proportion of that has increased but that's not really the diminished -- the new activity we're seeing as well so fairly good cross-section of new activity.
You know, obviously when Clearwater's building out the markets that they're building out, you should expect that we're seeing a lot of Clearwire activity as we talked about in the past, we'd expect that to continue for the next few years. As we mentioned, they're about 50% through their at least stated objectives. And then as we mentioned, won't really be any significant financial contribution this year but, we're certainly, I guess, heartened to see the plans from Light Squared and would expect to participate that -- in that materially.
Brett Feldman - Analyst
And to the extent you're seeing these 4G amendments, are they sort of living up to your expectations in terms of the increase and the size of the monthly lease? I think, for 3G, you saw maybe a 25% to 35% increase in the lease rate when an upgrade was there. Is that still the ballpark for a 4G upgrade?
Jay Brown - CFO
Actually, as we have talked about before, 4G amendments, because of the configuration on average, are running lower than your original 3G upgrade. I think that is pretty well true across the industry that the configurations are just typically lighter and so the upgrade is less and so the -- without getting into real specifics as we have talked about it several times, the 4G upgrade is less than your typical initial 3G upgrade. But, you sort of make it up in volume because we're doing a lot of --
Ben Moreland - CEO
I think Brett, one of the other things that we have talked to folks about is that if you look historically, we're probably seeing more activity with regards to 4G amendments and upgrade ahead of actually a product being available to consumers. And it's very difficult for us to know what is it going to look like once it's launched and actually you have consumer demand on the devices.
For us to see this level of amendments both in terms of the number of sites being touched and the amount of equipment being added, long before any of this is really commercially available to consumer, is not usual. So while the initial licenses and amendments are a little less than what we have seen in 3G, most of the 3G activity frankly was more commensurate with when devices were available. So we'll have to see how the product develops and what the usage is like and then watch as the carriers make adjustments as necessary once it gets out into the market.
Brett Feldman - Analyst
That is great color. Thanks a lot.
Jay Brown - CFO
You bet.
Operator
Thank you. And our next question comes from the line of Ric Prentiss with Raymond James. Please go ahead.
Ric Prentiss - Analyst
Thanks. Morning, guys.
Ben Moreland - CEO
Morning, Ric.
Ric Prentiss - Analyst
I want to hit two areas maybe. First on the distributed antenna system DAS, can you give us a thought on how big that piece of the business could become? Seems like a niche but a pretty interesting fast-growing niche. So how big for the tower industry in general and how big for you should we think of that becoming?
Jay Brown - CFO
Ric, the answer is I don't know. I'm very intrigued and pleased with what I have seen both in terms of activity on our own account and, then obviously, what the NewPath team brings to the table and the engagements that they have secured over the last few years. And the activity level that is, I think, generally picking up. And as I mentioned in my remarks, I think that is largely the result of all of our demand for data services that work in every little nook and cranny where towers can't necessarily reach or not sufficiently reach and so, a little bit of a change in the architecture is -- you know, you may think you've got adequate voice coverage in location which is true, served by a traditional tower network. But when you try to load that up with devices and data demands, it's clearly insufficient and so we're seeing areas that are DAS opportunities that maybe previously you wouldn't have seen before under a different demand profile for the network.
So how big it can be, I don't know. We certainly will invest going forward as we see appropriate opportunities and we have high expectations that there will be continued opportunities out there in the market. It will almost certainly always be a reasonably small component of our business just given the size of the run rate latest tower business today. It's just -- it's going to be. If it turned out to be a $50 million-a-year EBITDA business, that would be tremendous and we believe create value in that regard. But again, $50 million would be less than 5% of the total of the company.
That certainly doesn't diminish our enthusiasm, though, to making incremental investments that create value for the company and provide sort of a solution provider element for customers as they see opportunities in these markets and we are certainly well-equipped to not only secure the networks, build them out but then maintain them and operate them with the expertise we have as well as what NewPath will bring. And then our -- as you know, our distributed offices around the country, we've got district offices out there basically around our tower footprint, which is expensive and so we're pretty well set up to maintain and operate these systems and then further add to them over time in the coming years.
Ric Prentiss - Analyst
I appreciate the color that it is not in your guidance because I was wondering that. I didn't notice it in the footnotes last night. So it's not in your 2010 guidance. Can you give us a thought about, assuming it does close end of September, what might be coming into the fourth quarter? Is it something -- a couple of million? $5 million on the revenue EBITDA kind of line? Just trying to gauge roughly what we're looking for.
Jay Brown - CFO
Given that you'd only have one quarter, it's not going to be that significant relevant to a year where we do over a $1 billion of EBITDA, so it will come in in the third and fourth quarter and it will be a few million dollars. I think it's important -- let me give everyone a little more color around the NewPath investment and the way to think about it.
The NewPath investment of the $115 million at closing and then, obviously, we will be on board for capital spending for the continuation of their build plan of sites, of networks under construction, and our own for that matter, the NewPath investment stands on its own, based on existing networks on the air and contracted networks under construction.
So, in a very draconian view, which we certainly don't subscribe to, if that is all there ever was, the investment stands on its own and yet we see tremendous opportunity and have high expectations for further investment and further engagements on new networks that, obviously, add value to that platform. But the way we underwrote it, for obvious reasons, because as we think about allocating capital, we always look at sort of the opportunity cost of that dollar and what else we could have done with it. The existing book of business at NewPath results in the investment standing on its own.
Ric Prentiss - Analyst
And then on Light Squared, we have been hearing that they released 500 sites [searchering] in the Baltimore-DC area. I think they've got -- I think Denver and Phoenix are their initial market launches in mid--'11 and then it looks like Vegas and Baltimore-DC by the end of '11. How much demand are you seeing from them already in the application process and have you learned enough yet from them about what kind of back haul are they going to use? Because Clearwire obviously was using microwave backhaul. Any sense of what Light Squared is thinking of from a standpoint of venue or leasing?
Jay Brown - CFO
Yes Ric, I -- as true to our custom, I'm just really not going to get into any specifics around our discussions with Light Squares or what their build plan may be or their launch plan. That is obviously up to them to decide how to disclose that to the street. We all saw their press release recently and we were clearly gratified to see them with the public statements that they have made out there. But beyond that, I'm just not comfortable really describing any more detail of their build plan or backhaul plan, or what our potential marketshare penetration of that would be. Frankly, until there is more out there publicly from the customer, from the company, and until we get further into this down the road.
Ric Prentiss - Analyst
It's just GFT, good for towers, though.
Jay Brown - CFO
Okay.
Ric Prentiss - Analyst
Thanks.
Jay Brown - CFO
You bet.
Ric Prentiss - Analyst
Thank you, sir.
Operator
Thank you, and our next question comes from the line of Jason Armstrong with Goldman Sachs. Please go ahead.
Jason Armstrong - Analyst
Hey, thanks good morning. No new acronyms for you guys. But on the current debt deal, you've got a great runway on the maturity side of this point. Now, Ben, I wonder -- stepping back, can you help us think through how this frees you up in terms of thinking differently about the business? And in some respects, you have been a little bit restrained the last few years. In your mind, does having this behind you allow you to be more aggressive either on the deal side or share repurchase activity? Just how that shapes the thought process and then maybe just a second question on land purchases. They obviously accelerated in the quarter. How should we think about the outlook from here, is that something that continues to color it? Thanks.
Ben Moreland - CEO
Sure, Jason, let me take the opportunity to acknowledge Jay and the whole finance team. As he ran through quickly in his comments, if this financing gets done and we certainly think it will, we will have refinanced the entire balance sheet, over $6 billion, appropriately laddered out -- level-loaded out the maturity schedule as you would think is appropriate. Out as long as 10 years and one of them -- one little piece out 20 years. With over $6 billion refinanced in six quarters so it is a -- in our view, a fantastic accomplishment, speaks to the quality of our ability to navigate and operate through the securitization market.
Obviously it would have been much easier to just sort of rip off high-yield deals overnight but we saved ourselves significant amounts of money and coupon by being diligent and working through the securitization process which is, as most of you know, is a much more difficult process to go through but it is something we've become quite good at and I think it's frankly sort of a competency in the organization today.
You're absolutely right, Jason. Having completed, knock wood, this last financing and completed the entire refinancing of the balance sheet and laddered it out properly with an average coupon all in the vicinity of 6%, with that maturity schedule, in my mind, frees us up significantly in terms of flexibility. And given all of our experiences in the last fourth quarter of 2008, when we saw credit markets evaporate, we all have become appropriately more conservative in how you think about the availability of credit markets and can you in fact refinance debt when it's due.
With this last financing, that will be completely behind us for an extended period of time. In fact, the maturity schedule, pretty much, you could almost cash flow now in any given year. So I would say that, yes, as a management team, we will feel a big sigh of relief, have much more flexibility going forward. Also, if you noticed this financing that's out there today, has some excess proceeds in it which will go a long way towards satisfying the swap liability in February -- coming up in February of '11, so that as well will create some headroom in terms of liquidity freeing up. So, your observation is spot-on.
We will feel like we have more flexibility and intend to use it. And those of you who notice this behavior this quarter, where we didn't buy a lot of stock but we contracted to spending $115 million on NewPath, you can rightfully assume that we made the diligent call after an appropriate amount of evaluation that we wanted to put that capital to work in NewPath and thereby, not purchase shares in this particular quarter. And that is consistent with our behavior we discussed over time that we'll constantly weigh the opportunities. But you should not read into that that we're not a buyer of the stock. It's just that opportunity was there and we needed to save some cash from that. Now that this financing gets done, I think you will see us still significantly freed up and behave accordingly. And in the last on the land leases?
Jay Brown - CFO
Yes, Jason on your second question. We have done 8,600 deals to date, which means we have touched nearly 40% of our sites in the US and I would characterize this as the majority of the activity still to come is really opportunistic. And both opportunistic in terms of our ability to deploy capital and then get operating provisions in our leases that maybe make it easier for us to add tenants down the road. I think for the full year this year, we will probably end up spending somewhere in the neighborhood of $130 million to $140 million on our land purchase program, and then going into next year, I would expect that that would be up next year potentially in the neighborhood of $180 to $200 million as we've ramped back up our activity in the amount of land purchases.
We had, over the last year or so when we pulled back on Cap Ex, we focused most of our efforts on just doing lease extensions and now that we've fixed the balance sheet, I would expect that we will hopefully find opportunities to deploy a little bit more capital along those lines. You know, one thing that might be helpful just expanding on some of the comments that I made earlier about the land purchase program, is that it's not necessarily margin-enhancing for us to be buying theses properties.
As we look back over these 8,600 transactions that we have done, the combination of the impact to the P&L and site rental operating expense as we extend the land lease and, therefore, have a greater amount of land lease expense, a little bit more in cash but certainly more in the straight line impact of doing those transactions. That almost entirely offsets the reduction in rent that we see in the P&L from buying back the ground leases. So it's almost neutral to the income statement but certainly gives us control and predictability of the expense long-term as well as protecting the existing margins that are there today.
So hopefully that helps as you think about how to model it. I would give you a similar guidance for the go-forward that I wouldn't necessarily expect that the activity results in a reduction of rent as much as it does keep the level -- keeps the amount of expense relatively stable.
Ben Moreland - CEO
So by the end of this year, Jay, we will have spent about $500 million sort of like to date on this program for which you're not seeing a P&L benefit directly. Obviously, there is tremendous benefit in the portfolio composition. As you ran through in your remarks in terms of the average maturity, the number of sites that we control and the percentage of our gross margin and things like that. A huge movement out to the right on that but there is no direct financial P&L benefit from that approximately $500 million we spent like to date.
Jason Armstrong - Analyst
That is a helpful detail. Thank you both.
Jay Brown - CFO
Yes.

Thank you, our next question comes from the line of Simon Flannery with Morgan Stanley. Please go ahead.
Simon Flannery - Analyst
Good morning. You've obviously done the DAS deal with NewPath. Can you talk about the M&A environment as it currently stands for domestic towers? I think you've generally been fairly quiet thinking the multiples are up there. Any changes or anything you see you might like? And then there has been a lot of talk about weak conversion in the tower space. Can you just update us on your thoughts about that and your thoughts on timing? Thanks.
Jay Brown - CFO
Sure, Simon on the M&A market, we see some things out there that we like and there is a lot for sale. And some of them are very expensive and some are, we think, appropriate in the range of where they're looking for. Sometimes the challenge goes to the fact that we with a fairly mature tower portfolio with an opposite training multiple range, become challenged and sort of get stopped out on multiples where you may have a seller who has a very high-quality portfolio of sites that may have 50% of the revenue that we have on our typical sites. And so you might convince yourself from just an appropriate return perspective, the sites are actually worth a higher multiple but obviously a lot less per tower than our current trading multiple and therein lies the challenge.
Because notwithstanding the prospective return on that investment, it becomes very challenging, and we have been very vocal about this, very challenging to do something that is immediately dilutive and trust me you will like it in three or four years. That is just a very hard proposition, given the history we have all sort of lived there through. And obviously there is a certain amount of that we may tolerate but very little because our objectives are to continue to grow recurring cash flow per share, you know, as much as we can, obviously. This year the guidance as we've just updated it is 17%. We've got some work left to do this year. The year isn't over and I hope we do better than that and maybe even approach 20%. But that is just sort of a pet project around here.
So the market, I would say there are things we see, some things we like, probably some things we're going to go do. But it's the challenge with weighing that opportunity against sort of the current trading value where we are, and notwithstanding the fact that you may be using some cash or you may be using debt, we don't think about it that way. We think about it as a legitimate all-in cost to capital evaluation and we will continue to make our best judgement on where those opportunities are, how you create additional value, and always contrast that, as you know, with just buying our own stock and that is the way we're going to continue to behave.
Ben Moreland - CEO
On your second question related to reconversion, our current projections would suggest that we won't burn off our NOL until 2016 or beyond that date. So as we think of reconversion, which is really a tax-planning opportunity so that we minimize the amount of leakage of cash flow in the business and don't end up in a double taxation position between ourselves and the investor, it looks like that the reconversion and the planning for that is probably 2016 and beyond.
I think I would make an important point here. If ultimately we determined for any multitude of reasons that paying a dividend was beneficial ultimately to the value of the shares, we could do that earlier. And the benefit of that NOL would stay in place and any tax, any dividends that we did between now and that reconversion date, at least under current tax provisions, would be taxed as a C-Corp dividend, which would be much below ordinary income dividends which would be the case if we were to convert to a REIT and pay out dividends as a REIT. So I think there is some benefit to the tale here on our NOL but wouldn't expect absolute reconversion probably until that NOL provision -- our NOL position either runs out or nears its end and we're five or six years at least away from that.
Simon Flannery - Analyst
Is the dividend something that is near-term or is that more out two or three years?
Jay Brown - CFO
Yes, I think the steady payment of the dividend we're probably still some period of time away. As we think about it, it's really an allocation of capital and we think primarily if you've heard us articulate for a long period of time, and Ben's comments earlier about how we think about whether we think it's DAS or tower purchases or tower builds or buyback of shares. We're trying to allocate the capital in a way that we believe maximizes recurring cash flow per share so doesn't look in the short-term like that. That is going to be something we're going to want to do. But we'll continue to watch it and evaluate it based on all of the factors in front of us.
Ben Moreland - CEO
I think long-term, as we said before, I think long-term, the REIT conversion, the REIT designation for the tower business is very positive. I think it's is a terrific long-term structure to return a significant amount of the total return in the form of a predictable dividend. And so I look forward to that day. Prior to that, I think we would have to see something very compelling to pay a dividend as a C-Corp and have 20% if that is what ultimately happens with C-Corp dividends, 20% tax leakage between us and our shareholders. Whereas we could have taken that capital, that free cash flow and just bought shares and deferred that tax until ultimately it's a single taxation in a REIT structure. So again, as Jay says, we'll watch it very carefully. Certainly don't have any quarrel at all with the REIT model, in fact welcome it. But for us, I think we're still a few years out.
Simon Flannery - Analyst
Thanks very much.

Thank you, our next question comes from the line of David Barden with Bank of America Merrill Lynch. Please go ahead.
David Barden - Analyst
Hey guys, thanks for taking the questions. Just two maybe. First, and I am sorry if I didn't pick up on this, but just with respect to NewPath, could you kind of outline how did you find these guys? And if more companies like them were out there, which they presumably are,and were for sale at these kinds of valuations, are you prepared to exercise some kind of DAS roll-up of all these private providers? Or is this kind of a one-off?
And I guess the second question would be, maybe Ben. I don't know, you have probably been following this. The Congress and Senate seem increasingly creating a consensus that maybe auctioning off the 7MHz D-block is not their preferred option and rather they seem to be creating some momentum behind carving out funding and creating the opportunity for public safety to build their own network, which would be an incremental network opportunity for the tower sector and guys like T-Mobile and others would have to find other opportunities. But have you got any sense or maybe I would love to see -- hear your color on what you think the prospects are for a public safety network being an incremental opportunity. Thanks.
Ben Moreland - CEO
Okay, thanks David. First of all on NewPath, we have known NewPath since inception. In fact, the founder -- one of the two founders of NewPath was a former Crown employee and so we've stayed close to them, have been admirers of what they have done as a competitor, because we've been competing with them for several years and really like the entrepreneurial spirit and the way with which they have built their business.
And, frankly, the concentration or amount of business they have secured from Big 4 wireless carriers, which is obviously a -- certainly a real feather in their cap and credibility in our eyes in terms of how they've operated and conducted themselves, and think that they will fit very very well with our team. And we're along the way sort of in an integration plan as you can imagine and I think they'll roll right in and really become the real nucleus of our DAS team where we will, obviously, contribute both our existing networks and employee base that we have working there as a combined team. We're very optimistic.
So, for planning purposes right now, David, I guess we would always take a capital allocation approach to looking at anything on the market, but we're going to be pretty pleased with this platform, and the track record that both our team and their team bring together, I think, make us pretty formidable competitors in this market. And the real opportunity is on the growth and in further investment and getting engaged on new networks. And so, while I'd never said never, if there were something else out there available, we'd certainly look at it. This is certainly going to be our platform for the go-forward.
Jay Brown - CFO
On the D-block, I have been reading the same things with some, I guess, cautious optimism that you could see a new network requirement come out of the public safety discussion. I wouldn't have probably any more developed opinion than many on this call, given that we have seen the public safety initiatives stop and start and be on and off again, and it has become difficult to rely on that for planning purposes for our Company.
I think we can certainly all acknowledge is the need for a common platform around public safety, and it looks like there is some thought coalescing around that and we would certainly do whatever we could to facilitate that and be a strong partner. However that gets built out and I would certainly not say that it's in our current planning horizon.
David Barden - Analyst
Okay, great. Thanks.
Jay Brown - CFO
Yes.
Operator
Thank you. Our next question comes from the line of Jonathan Atkin with RBC Capital Markets. Please go ahead.
Jonathan Atkin - Analyst
Yes, I was curious about the services business and what drove the revenue and cash flow trend. Seems a little higher than prior quarters. And then on revenue-enhancing Capex on existing sites, is that something you expect to trend fairly flat going forward or is there any reason that would go up or down?
Jay Brown - CFO
Okay, yes hey Jon. On the services business, I'll just tell you that we're continuing to increase our take rate up materially, I might even say dramatically, over the last two years. And that is a direct credit to the folks that are running that business for us and the folks that executing that business in the field, dealing with our customers on a daily basis. Not only with new installations which have been more the traditional bread and butter of that over time, but we're doing a lot of work on amendment activity as well. And I mentioned briefly in my remarks expanding the scope and we're even doing some side [atkins] zoning work for folks, really managing the whole front end of their application process on our site all the way to completion.
And so, real credit to our team, and that while I would like to tell you -- would love to tell you that all the volume increase from the services is because of all the new leasing activity we're seeing, that would not be quite accurate. It's really because of the take rate in terms of the percentage of time when somebody's touching our site that we're actually engaged to manage that process -- that installation process for them has increased dramatically. And again that is just a credit to our team and the way we operate with customers.
On the revenue-enhancing front, we're seeing that pleasantly trend down and I'm kind of optimistic that we continue to get better at how we're spending capital to enhance sites, making very smart business decisions every single time around where you're enhancing sites and to what extent. As well as I think there's -- this is not -- I can't prove this but I -- we believe we're seeing the trend where we have taken a couple of passes through the portfolio generally on making improvements, and feel like we're over the hump on improvements.
And so we've got some capacity in the portfolio we able to benefit from now as we see applications come through. So, I would not expect it to pick up and I have been pleasantly surprised to see that it looks like 2010 is going to be less than 2009 and maybe that continues.
Jonathan Atkin - Analyst
Thank you. And then on carrier portfolios, I'm wondering if you're finding that they're becoming more competitive with standalone tower companies from a leasing attractives standpoint, and do you think that there might be any asset sales over the next several quarters?
Jay Brown - CFO
I think there will be. I think there are some out there under consideration and, obviously, we'll stay close to those situations and I won't mention any by name. I am certainly aware as any prudent owner of a power portfolio would do, they're out there. The carrier towers for the most part are out there actively being marketed for co-location opportunities, and that is completely appropriate, and we compete at that level. So I certainly don't suggest anything otherwise and I think we will see probably some asset sales here in the next sort of medium term but that is just speculation at this point.
Jonathan Atkin - Analyst
Sure. And then on Light Squared, without getting into any kind of quantitative detail, do you expect that you would be signing leases this year?
Jay Brown - CFO
We certainly hope so. We certainly hope so. That is sort of the plan we're working on under but beyond that, and again I don't think it would have really any material impact this year, and beyond that, we'll just wait and see how they further describe their deployment plans to the public going forward.
Jonathan Atkin - Analyst

Our next question comes from the line of James Ratcliffe with sponsored links Barclays Capital.
James Ratcliffe - Analyst
Barclays Capital, I guess our links are sponsored, I don't know. Morning guys, thanks for taking the question. I wanted to talk --, AT&T in particular has been talking a good bit about the expanding of the WiFi coverage with WiFi zones and heavy usage areas and major cities and the like. And I am wondering how -- if that is an opportunity for you in terms of infrastructure and actually in terms of WiFi antennas and towers, and just how much exposure you have to dense, urban environments like that, versus more suburban, rural and that?
Jay Brown - CFO
Yes, I would say to the WiFi question, I guess what I would say is the way I think about it is there is going to be offloading technologies. There already are and those of us with iPads are on WiFi a lot with them. There is going to be offloading technologies that augment the capacity of these wireless networks from now on and I think over time, we'll have an increasing role in satisfying all of our desire to be untethered and have robust high-speed wireless access. But there is a limitation on what that ultimately can do, whether you're sitting in a restaurant or an airport and so you go from there really almost in a continuum in my mind, you go from there to a DAS network. Which is outside, connected directly to fiber.
So high-speed, reasonably close proximity to the antennas, potentially in a residential area or a venue. And it really comes -- you sort of start with a continuum of what the architecture looks like. So you're sitting in your house, roaming on your own internal WiFi system or in a public location, and you then sort of get outside of that and you need to hand off capability, mobile capability and maybe that takes you into a DAS network.Then you get out onto a more major artery where you have a lot more traffic and a lot more loading in the system, and that rolls you into the traditional terrestrial tower network.
And so as we have studied this more and more, I have got very comfortable that it takes really all of these types of architectures to deliver the enormous amount of bandwidth and capacity that were all requiring. And it really looks a lot like the internet adoption curve and there is just no way that a -- frankly I think, there was some pretty interesting industry data out recently where I think it's unlikely that the wireless spectrum, and the wireless networks that are built around that spectrum, will be able to satisfy all of our demands for wireless services. And so it is really going to take all that working together and that is why we got comfortable that DAS is not by any means, in our view, a threat to the tower network. It's merely complimentary and I would say the very same thing about WiFi notes and ultimately even [simto] cells if you want to go down that path. I think it really takes all those types of network architectures deployed to try to keep up with what we currently see and what you can expect to see in the future.
Ben Moreland - CEO
All right. Got time for one more?
Jay Brown - CFO

Operator
Thank you, our next question comes from the line of Jonathan Schildkraut with Evercore. Please go ahead.
Jonathan Schildkraut - Analyst
Thanks for squeezing me in guys. Actually, it's Jonathan Schildkraut. Just two quick questions here as most have been asked and answered. In terms of the bond offering that you have out there, previously you have indicated your goals were kind of investment grade. I'm wondering what your expectations are. And then secondly, if you could just refresh us on your view into some of the international opportunities. We're now seeing both of your larger peers move into Latin America. Thank you.
Jay Brown - CFO
Jonathan, on the first question, I'm just going to have to ask you wait until we issue a subsequent press release. I really can't talk about the offering that we have in the market currently. But as I spoke about, we believe that we'll be successful there and hopefully once we are, we'll put out a press release and give you all the details and be happy to answer any specific questions about it once it's done.
Ben Moreland - CEO
Historically, the securitizations have been investment grade.
Jay Brown - CFO
Yes, historically they've been investment grade.
Ben Moreland - CEO
In terms of international opportunities, Jonathan, we continue to look and study and see opportunities that are out there in the marketplace, and as yet have not found something that we've been prepared to pursue aggressively enough to win in an auction if you will. That doesn't mean we won't in the future. So I am not going to foreclose the opportunity. And as you know we have in our business in Australia so we have a view in an international market today. But I would say that we're very focused on the opportunity we see in the States.
From our perspective, it is the fastest-growing wireless market in the world and it is not something you could have said a few years ago. We are I think in the US probably among the leaders, if not the leader, in terms of wireless technology today and where we're headed. The amount of investment that's being deployed in these networks and the incremental returns that the carriers are able to command from those investments, in my mind, make the US market somewhat unique. Because that is clearly not the case in some other markets that we are -- that we have looked at.
So I will not foreclose the opportunity. We'll continue to remain educated and aware of what is going but as we sit here today, we are quite enthusiastic about what we see in the US market and the opportunity before us. And that is likely to be our -- where most of our effort continues to be focused.
Jonathan Schildkraut - Analyst
Great and if I can ask -- just ask one more. Ben, during your prepared comments, you talked a little bit about the 4G rollouts relative to what you had seen with some of the 3G activity. And that with 4G, this activity was coming in front of maybe some of the devices on a consumer demand.
And I think what we saw, at least with 3G, is we saw an initial overlay and then kind of a lot of back filling, which has been the incremental demand that's benefited the industry. With the 4G buildouts, are you anticipating the same type of activity or were you trying to indicate that maybe with the initial rollouts, carriers were going a little bit deeper in terms of their initial overlays.
Ben Moreland - CEO
Yes, no, thanks for the question. For clarification, we see exactly the pattern we've seen before, where you have a network rollout and then you have significant backfill or augmentation going through a market as they pick up additional sites, commensurate with adding subscribers to the network.
We're absolutely seeing that already with some of those the markets that have been launched, and we would expect that to be a significant component going forward. And if you think about it from the carrier's perspective as they roll out, that is a very efficient thing to do. Because obviously, you're trying to spread your marketing and your customer acquisition dollar, and so to go back and augment an ad to a market that is already on the air is a very efficient thing to do, and a very significant component of what I think will be the next few years of 4G leaseup. And if you get out on some of the websites and look at the coverage maps out there, I think you can see exactly what we're referring to. There is a long way to go in the markets that have already been deployed.
Jonathan Schildkraut - Analyst
All right, thank you very much for taking the questions.
Jay Brown - CFO
You bet.
Ben Moreland - CEO
With that --
Jay Brown - CFO
Yes, I think we're right at an hour end so maybe we'll end the call there.
