Thank you, Leslie.
Before I review our results and provide our outlook for 2012, I'd like to provide an update on the response we've seen to our new Vonage mobile app which we launched last week. Vonage Mobile is the most exciting product we've offered since the launch of our initial VoIP service and continues our heritage of offering innovative products that deliver great value and convenience to customers.
If you have not yet downloaded the app or seen last week's press release, let me take a moment to describe it for you. Vonage Mobile is a free downloadable application for iPhone and Android that lets users make free high-definition calls and send free texts to all users of the app worldwide. It works over WiFi, 3G, and 4G wireless data networks. When calling people who don't have the app, users get ultra low-cost calling worldwide with pay per minute rates that are on average 70% less than major mobile carriers and 30% less than Skype. Vonage Mobile consolidates the best features of our prior applications while adding important functionality, better value, and improved ease of use.
Early interest has been extremely positive. There have already been over 500 stories published globally, and we have substantially exceeded our pre-launch expectations of 100,000 downloads in the first week. Most user reviews have been very favorable. We plan to release improvements and new features every few weeks. Vonage Mobile combines the best of free voice and messaging services with exceptional high-definition audio and incredible value for traditional international calling, all while using the existing mobile number and address book. If you haven't downloaded the app, I encourage you to do so and let us know what you think.
The successful development and launch of Vonage Mobile is emblematic of the strategic and operational progress we have made transforming our company. As we close out one year and begin the next, I'd like to provide some context for where we are and how far we have come. Over the last three years, we've completely transformed the operational, financial, and strategic dimensions of our business. Operationally, we've upgraded systems, streamlined processes, improved the customer experience, and stabilized our subscriber base. Through these efforts, we've dramatically improved our operating and financial results, driving over $200 million in EBITDA improvement while significantly improving customer satisfaction ratings. By lowering churn from highs of nearly 3.5%, we reduced customer losses from 155,000 in 2009, to 30,000 in each of the past two years. And operational improvements have enabled us to lower our cost structure to its lowest level in six years.
Building on a sustained operational performance, we completed two comprehensive refinancings in a span of eight months, lowering interest rates from a high of 20% to less than 4% and cut our overall debt levels by two thirds, saving $43 million in annual interest expense. Not that long ago, our business was unprofitable and burning significant amounts of cash. In 2011, our business generated nearly $100 million in net income, and for the past two years has generated more than $100 million in free cash flow. And the decision to account for our $800 million in net operating losses as a deferred tax asset this quarter reflects our strong possibility and expectations for continuing future income. Many did not think these results were possible.
A perhaps more subtle, but equally important shift, has been on the strategic front. In 2009 we identified an opportunity to leverage our technology and position in the domestic home phone market to concentrate on international long distance callers, which led to the introduction of Vonage World. This calling plan has grown into our flagship product, representing more than 70% of new customer additions. Approximately half of our customers are now on the Vonage World plan, and approximately 35% of our entire customer base are international long distance callers.
As our emphasis on international callers and sales of Vonage World increased, service ARPU grew. Service ARPU has increased by 9% cumulatively over the three-year period. In parallel, we drove structural cost reductions throughout the Company, enabling us to absorb the cost of our dramatic growth in international long distance minutes, while maintaining direct margins at 68%. Over the past three years, we've lowered international and domestic termination rates by more than 25%, reduced customer care costs per line by 29%, and cut the cost of our devices by nearly one-third. Together, these initiatives helped to improve EBITDA from a nearly $50 million loss in 2007 to a positive $160 million EBITDA during 2011.
While we've largely offset general market trends in declining domestic phone service, meaningful revenue growth has not materialized as quickly as planned. For 2011, service revenue at $867 million was basically flat from 2010. We must do better. Quality revenue growth is our top priority for 2012. Allow me to share our plans for executing on that priority.
With the Company now on a solid foundation operationally and financially, the time is right to accelerate our investment in our key strategic growth initiatives. In 2012, we will invest in the following areas the heart of our growth strategy. The first is international long distance, where we will continue to penetrate ethnic calling segments and grow subscribers through our retail channels including event teams. The second is mobile services, which builds on the Vonage Mobile platform. And the third is international expansion, as we plan to enter new geographic markets outside North America and the UK.
These planned investments will lay the groundwork for success in new markets as we increase our organizational capacity and launch new services. We will invest in areas such as product development resources, business development talent, network enhancements, and marketing. We plan to invest in a range of $5 million to $10 million per quarter above 2011 levels. Of course, we will tightly manage this increased spending with the same financial discipline that has driven our financial turnaround. A substantial portion of these investments will be success-based, allowing us to redirect or reduce investment levels if target results are not being achieved.
Reflecting the additional investment in strategic growth initiatives, we expect to generate EBITDA of $30 million to $35 million per quarter during 2012 and $100 million to $140 million for the year. With these initiatives in the early stages of execution, it is too early to predict their level of success. However, we are targeting large markets with robust technology platforms and a well recognized brand. We believe these growth initiatives have the potential to achieve over $100 million in annualized revenue within two to three years.
Let me now discuss each of the growth initiatives in a little more detail. We continue to execute on our strategy to penetrate international calling segments and have substantially grown our base of international callers over the past three years. This success reflects the prioritization of our marketing sales and customer care teams to target and support international callers. In the past two years, we've increased our bilingual support by opening three new sales and service centers.
In 2011, we grew our Hispanic calling base by more than 50% through highly targeted marketing vehicles, more relevant messaging, and enhanced products. We continue to have ample runway to grow our international base. 10% to 15% of all US households are moderate to frequent international callers, using a mix of both home and mobile phones. The majority of these callers are paying three to four times the rate they could be getting from Vonage, and the average Hispanic international caller spends $40 to $50 per month on international long distance service. With Hispanics comprising 16% of the US population, this large and rapidly growing segment continues to be an attractive opportunity for us. While the opportunity is significant, churn profiles for this segment are higher than other segments, partly due to socioeconomic factors. To help reduce churn, we are evaluating a range of initiatives including alternate payment vehicles that would allow cash transactions.
In 2011, we significantly expanded our retail distribution. Through new retail partnerships with Best Buy, K-Mart, and Sears, we doubled our store locations to 6,000. We also now have nearly 60 event teams up from six in January of 2011 operating in ethnic concentrated markets across 18 states, including California, Texas, Florida, and New York. These performance-based selling teams market and promote Vonage service in Hispanic and Asian Indian events and community gathering places. In the fourth quarter, retail sales comprised 19% of gross line additions, more than double the 8% level of the first quarter. During the fourth quarter, gains in this channel were partially offset by softness in other channels, resulting in flat sequential gross line additions. However for the full year, gross line additions were up 5% over 2010. In 2012, we expect that sales from our expanded and indirect channels will grow to more than 20% of gross line additions.
Our focus on mobile builds on our success targeting international long distance callers in the US. The power of this opportunity comes from leveraging our international long distance experience and termination rates, which are among the lowest in the world, along with fundamental market trends, including increasing global access to broadband networks and wi-fi, accelerating smartphone penetration, and consumer comfort with downloadable applications. Our mission is to be a leading provider of low-cost communication services connecting people through broadband devices worldwide. To that end, last August we introduced the very successful Extensions product, which enables Vonage World subscribers to extend calling to their mobile phones. And now with Vonage Mobile, we build on all of our previous apps to provide a compelling all-in-one on-net and off-net voice and messaging service.
With Vonage Extensions and Vonage Mobile, we are rapidly establishing the Company as a leading provider of quality mobile voice and messaging services. We're very pleased with the early success of these products. Vonage Extension has clearly struck a chord with customers and now has nearly 500,000 users, and Vonage Mobile is off to a great start. Future releases will integrate MMS, a low-cost international roaming capability, and our extension service, and we continue to evaluate the benefits and technical options for mobile video as well. Many other features and improvements are on the road map this year.
Our final growth initiative is geographic expansion. The global consumer communications market outside North America is more than $200 billion, and it's growing at nearly 7% per year. We plan to capitalize on this opportunity and expand our geographic footprint primarily through partnerships, and we expect to announce our first partnership soon. We plan to announce an international friends and family offer whereby we exchange and terminate traffic with a foreign carrier, jointly providing lower rates to consumers while expanding our customer base and that of our partner. Additionally, we're actively exploring the delivery of full voice communication services to be marketed and distributed as a complement to an existing foreign provider's product suite.
In 2011, we assessed the market landscape and put strategic plans in place to guide the execution of our growth initiatives. We built out our R&D capability in Israel, began to staff our international expansion team, and accelerated a number of new products we are bringing to market. Our core business has been stabilized and is generating significant cash flow. We're now focused on the next phase of our transformation, and we are pleased to be in a position to invest in opportunities in attractive new markets. We believe customer interest in Vonage Mobile is evidence that we are making the right investments.
Before I pass the call to Barry, I'd like to thank our dedicated employees who have enabled our transformation. They worked tirelessly to enable us to reach this point, and I look forward to announcing continued progress toward our key objectives through 2012.
And now I'll turn the call over to Barry who will review our financial performance in greater detail.
Barry Rowan - CFO and CAO
Thanks, Marc, and good morning, everyone.
I'm pleased to review our financial and operating performance with you. In 2011 we delivered record high financial growth and continued to build on the earnings and cash flow momentum established over the past several years. For the fourth consecutive year we generated positive and growing EBITDA, and for the third consecutive year we reported positive and increasing net income excluding adjustments, which more than doubled from 2010. We've improved our balance sheet dramatically through transformative refinancings we completed over the past 14 months. Our strong operating performance and lower interest expense combined to generate $108 million or $0.48 per share in free cash flow. This was our second year of positive free cash flow, and each year generated over $100 million. With our core business now stabilized and highly profitable, and with a fresh balance sheet, we are well-positioned to execute on the next phase of Vonage's transformation through accelerating our investment in the strategic growth initiatives Marc outlined.
Let me now move to a review of our financial performance beginning on slide three. Our results in the fourth quarter were generally comparable to those reported in the third quarter of 2011. In the fourth quarter we generated EBITDA of $40 million, our fifth consecutive quarter of EBITDA at or above $40 million. For the full year, we grew EBITDA to a record high $168 million, achieving our guidance of at least $165 million provided on our first quarter earnings call last year. This represents a 7% increase over the prior year, as we delivered operational improvements across most segments of our business. Through an aggressive focus on driving operating efficiencies, we reduced the unit cost of (inaudible) by approximately 10%, lowered costs of selecting services by 3%, and reduced customer care cost per line by 11%. We generated these strong results even as we absorbed a $15 million increase in the cost of selecting services from our targeted international long distance users. We generated more than 20% higher minutes of use than during the prior year.
Moving to slide four, in the fourth quarter we reported net income of $25 million or $0.11 per share excluding adjustments, up from $15 million or $0.07 in the prior year's quarter, an increase from $24 million or $0.11 sequentially. Net income more than doubled for the first year, growing to $96 million from $47 million in 2010, excluding adjustments. This is our third consecutive year of positive and growing net income excluding adjustments, reflecting our continued improvement in operations and sharply lower interest expense, which declined $31 million from 2010.
Let me take a moment to discuss the release of our net deferred tax asset valuation and the associated impact on our financial statement. Accounting rules require that we record a valuation allowance against our net deferred tax assets if we determine that it is more likely than not that we will use the net operating loss carryforwards prior to their expiration. Until the most recent quarter, we had recorded a valuation allowance, which reduced our net tax deferred assets to zero.
In the fourth quarter of 2011 we concluded that based on past profits, as well as our expectations for future net income generation, it is more likely than not that we will use our NOL carryforwards prior to their expiration. Therefore, we released the related valuation allowance against our United States and Canada net deferred tax assets and now recognize the value of the NOLs as an asset on our balance sheet. This resulted in a non-cash income tax benefit of $326 million and a corresponding net deferred tax asset of $326 million as of December 31, 2011. Please note that while this accounting adjustment will lower net income in the future by the effective tax rate, it will not affect the cash taxes paid by the Company, which will continue to be offset by the approximately $800 million in net operating loss carryforwards that we had at the end of the year. The net result is that we expect to recognize income tax expense in 2012, but this will be a non-cash expense.
Reflecting this one-time gain of $326 million, GAAP net income for the quarter was $350 million or $1.55 per share. This is up from a net loss of $42 million or $0.19 per share in the year ago quarter and up from net income of $16 million or $0.07 in the third quarter, both of which included charges related to refinancing our prior debt.
As you can see on slide five, total revenue for the quarter of $215 million was stable relative to both the sequential and the prior year's quarters, declining less than 1% from each. On an annual basis, total revenue declined to $870 million from $885 million in 2010, primarily as a result of a $12 million reduction in deferred revenues from legacy activation fees. These were largely phased out in mid-2009 to provide more straightforward pricing for our customers, and this nonoperating issue does not impact EBITDA. In addition, equipment and shipping revenue declined $8 million as we know longer charge for customer equipment.
We continue to strengthen the quality of our customer base and revenue mix as we grow the number of customers on Vonage World, which now comprise approximately 50% of our base. 35% of our total customer base are now international long distance callers who make at least 20 minutes of ILD calls per month. While the cost of telephony services for these customers is higher due to their long distance usage, they are attractive customers, as they typically churn at lower rates than domestic callers.
Aided by the mix of Vonage World subscribers, we've increased average revenue per user, or ARPU, in each of the past three years. For the fourth quarter, telephony services ARPU was stable sequentially at $30.12. On an annual basis, service ARPU increased to $30.22 and is up 9% since 2008, as we've attracted customers on higher rate plans and selectively increased prices as we enhance the value of our offerings by adding features such as unlimited 411 calling and Vonage digital voicemail.
Please turn to slide six. We added 169,000 gross lines in the fourth quarter, on par with both the fourth quarter of last year and sequentially. But we've been pleased with the increase in sales to our retail channel, which was largely offset through declines in other channels, resulting in a minimal change to overall results in the fourth quarter. Reflecting progress adding Vonage World customers and in line with our guidance for higher gross line additions for the year, GLAs grew by 5% to 672,000. We improved our marketing yield by 2% in 2011 from 2010, as subscriber line acquisition costs declined from $310 to $304 for the year. We acquired more customers through lower-cost retail channels.
Fourth quarter churn of 2.7% was flat compared to the fourth quarter, but we saw some benefit as planned from customers in their 13th to 15th month of no-contract. These gains were offset by higher churn in some international calling segments. Specifically, churn tends to be higher among our growing base of Hispanic subscribers relative to other international callers, as Marc described. And we saw some increased competitive pressures in other ethnic segments. As you may recall, we eliminated contracts in September of 2010, creating upward pressure on churn during the subsequent 12 months. In the first quarter, we will be providing customers a choice, offering those entering into a service agreement the promotional discount in place at that time.
Increases in churn in the second half of the year led to full-year churn of 2.6%, which matched the full year guidance we provided on the last earnings call. While we were disappointed with the 20 basis point increase in churn from the prior year, we believe reinstating contracts will help mitigate some pressure on churn during the latter part of 2012. The combination of slightly lower gross line additions on flat churn resulted in 14,000 net line losses in the fourth quarter, an increase of 5,000 lines lost compared to the third quarter of 2011. The 30,000 in net line losses for the year was stable with the levels experienced in 2010. As we discussed, our strong EBITDA results for the year resulted from a commendation of stable ARPU and an aggressive focus on operational improvements, which has substantially improved our cost structure.
Moving to slide seven, in the fourth quarter, cost of telephony services or COTS of $59 million was flat sequentially and up $1 million from the same quarter a year ago, as we've increased the number of international long distance callers. On a per line basis, cost of telephony services was $8.24, flat sequentially and up from $8.06 a year ago. We maintained direct margins of 68%, both sequentially and compared to the prior year's quarter. For the full year 2011, total cost of telephony services was a very strong story, beating our internal targets. We reduced total cost to $236 million from $244 million in 2010, driven largely by a 38% decline in domestic termination costs, structural cost improvements which helped to offset the rate of growth in COTS for international callers, and E911 vendor consolidation, which saved $4 million annually. Going forward, we expect growth in COTS from continued increases from international long distance calling to partially offset by the next generation call routing and peering relationships we are implementing.
On slide eight, SG&A of $59 million in the fourth quarter was flat year-over-year and sequentially. On an annual basis, our focus on driving efficiencies throughout our operations resulted in further improvements in SG&A, with SG&A declining 2% to $235 million during 2011. Since 2007, we have lowered SG&A by $87 million or 27%, and we've made operational improvements in virtually every area of the business. A substantial portion of these savings has come through improvements in our customer care operations. We reduced care cost per line 11% in 2011 on top of the more than 20% reductions in each of the prior two years. These gains in 2011 came from improving first contact resolution and our call-handling efficiency. We see further opportunities for gains including, for example, improving customer contact to best-in-class levels, additional reductions in customer handle time, and through more customers accessing our online account managing systems, which we continue to enhance.
Moving to slide nine, while marketing expenses were roughly flat sequentially, we continue to optimize the mix of media and channel expenditures to meet our marketing objectives. For the year, marketing expense increased $6 million or 3% to $204 million, primarily related to the expansion of our retail channels. The increase in spending, as I mentioned, contributed to the 5% increase in GLAs.
Now let's move to a discussion of our CapEx, cash flow, and balance sheet. For the second consecutive year, we generated significant cash flow through the combination of ongoing operational improvement and the benefit of our debt refinancing. Looking at slide 10, CapEx for the year totaled $39 million, in line with our guidance for CapEx not to exceed $40 million. During 2012, we expect capital expenditures, including information technology infrastructure investment, to remain at comparable levels in the $40 million to $45 million range. We are pleased to report that we generated $108 million in free cash flow for the year, meeting our guidance of at least $105 million. Free cash flow grew 27% from the prior year after eliminating the impact of a $69 million swing in working capital as 2010 benefited from prior year purchase discounts. We reduced interest expense by 65% from 2010 to $17 million, which contributed meaningfully to the strong performance.
We exit 2011 with a pristine balance sheet characterized by low leverage and low interest rates. Total leverage was 0.5 times debt-to-EBITDA, and allowing for the cash on the balance sheet, net debt was $30 million or 0.2 times. The interest rate on our term loan is at LIBOR plus 325 basis points based on our current leverage ratios.
Now that we have stabilized our business, are generating meaningful cash flow, and are operating with a completely fresh balance sheet, we are in a position to invest in the strategic growth initiatives Marc has described. While most of the investment will be in the category of SG&A, our efforts include a broad organizational realignment as we staff to expand our product development capabilities, ensure that we have the requisite skills to market our products, enhance our network to accommodate worldwide mobile calling and add capacity to develop additional business partnerships. Again, we expect these increased investments will range from $5 million to $10 million per quarter versus 2011 levels. We will certainly manage this additional funding with the same discipline that has characterized the Company's financial turnaround over the past several years.
Reflecting these increased investments we are targeting $30 million to $35 million in quarterly EBITDA throughout 2012. We've established this range of guidance to provide appropriate flexibility to manage the investment of our growth initiatives as they develop during this year of strategic transition. We believe that redoubling our commitment to achieve quality sustainable revenue growth through these initiatives represents a high priority use of a prudent portion of the strong cash flow we are now generating from our core business. Even with this increased level of investment, we expect to add cash to our balance sheet during 2012, while of course moving our obligations under our current debt agreements.
Based on these plans let me reiterate our guidance for 2012. EBITDA of $30 million to $35 million per quarter and $120 million to $140 million for the year, reflecting additional investment in strategic growth initiatives. Capital expenditures in the range of $40 million to $45 million. Thank you again for you interest in Vonage, and now I'll turn the back over to Leslie to initiate the Q&A session.
Leslie Arena - Director, IR
Thank you, Barry. Operator, please open the line for questions.
Operator
Thank you. (Operator Instructions) Our first question comes from Michael Rollins of Citigroup.
Michael Rollins - Analyst
Three, if I could please. The first one, is Marc, you mentioned the success of the new application in terms of, I think you mentioned over 100,000 downloads in the first week. Can you share with us how that compares to the last couple of mobile product launches that you've done? How we should think about the way they should ramp? The second question I had was, you also described an expectation for incremental revenue, I think you said within the next few years, of $100 million. Can you talk about what the margin potential for that is and how to think about the cash contribution from that type of revenue growth? Then finally, if you could just talk about the churn and what is keeping the churn elevated from where it was earlier in the year and maybe where initially you are hoping to get that number down to.
Marc Lefar - CEO
Sure, Mike. Thanks for the question. Let me take them in order.
On Vonage Mobile, just to clarify, we had some ingoing expectations that we would be pleased if we were able to generate 100,000 downloads, with basically virtually zero marketing spending in the first week. We've blown by that number by several-fold and are pleased with the traction. It is very difficult in something that's only a week old to look at the viral nature and how it is spreading, but the expectation for us at this point based upon how it compares to other applications. In day five, for example, we were seeing that, that acceleration was double what the downloads were from day one. That's a very different dynamic than what we saw which is more straight line continuous motion from prior applications.
That combined with increasing positive ratings both in the Android market and in the iTunes store as what we're seeing in terms of the number of an invited friends that people now have they can talk on net, gives us some optimism that we think this could grow pretty quickly. It would not be unrealistic for us to hit ballpark of 1 million downloads by end of quarter, certainly at current course and speed. Again I want to warn folks that it's only a week into it and very difficult to forecast a trend based on one week, but we are encouraged at the early signs, and it is growing much more quickly than our previous experience.
Let me hit the churn comment, then I'm going to ask Barry to talk about the margin potential on the $100 million of new revenues. From a churn standpoint, as you know, one of the drivers that caused us an uptick in churn over the past year was the elimination of contracts and service agreements. We are putting that back in place this week, and we expect that will start to give us some improvement in the back half of the year as a greater percentage of our customer base is on contracts. So, we have that and we can model that. The other elements of the mix, the Hispanic customer base has a higher churn profile, frankly that we expect it to be. Obviously, it's grown much more quickly during the year.
Let me break down a couple of the areas for churn. Just for clarification, although there has been a mix in terms of where some of the churners have gone, our non-Hispanic domestic callers, that churn rate has been dead flat for the last five quarters, so there is virtually zero change in that portion of the customer base. The largest single increase in churn has come from Hispanic customers. Break that into two pieces, domestic and international users. The domestic Hispanic customers are churning at extremely high rates. They've increased dramatically over the last few months. We see that having been able to look at them, after the fact as really socioeconomic issues. It is evidenced by having poor or unscoreable credit. As we talked to these customers we understand it's an issue of trying to manage their finances on debit cards and credit cards pretty much on a monthly basis. So, automatic charges to those cards tend to be the things that cause them problems and throw them into great status and suspend. So, we're trying to work on different types of structures of calling plans, as well as alternate payment vehicles that we think can help to improve that churn. There is definitely high levels of satisfaction and desire for the product, but this is getting to an ability to pay for that product that we need to try to manage.
In the international Hispanic segment, that has much, much lower churn rates. It parallels the international versus domestic differentials we've shared with you in the past. But it is also increased for some of the same reasons. It's still quite lower -- quite a bit lower than our average, but because there is a large number of Hispanic international customers, it's increasing the average. Many of the same tactics that we're pursuing in the domestic market, we think will help in the international area.
The final area that had an impact for us, particularly in the fourth quarter, and we've actually seen improvements here in the first month of the year as we have taken action, has been competitive smaller focused promotional offerings going after Asian Indian customers. So, there are a couple of small branded players using everything from prepaid to digital virtual calling cards that have been aggressive in targeting our Asian Indian base in the fourth quarter. Candidly, we did not have particularly good retention offers for those customers. We now have the ability to real-time re-rate or match and provide alternate rate plans when necessary to meet competitive offers. We've seen that starting to improve our business in the fourth quarter.
In terms of guidance, there are a couple of things that cut both directions. So, the Asian Indian churn levels, we feel that we've got that in check. We feel like that's moving in the right direction, and we definitely expect to see benefit from the return to service agreements or contracts. We believe that the movement in the domestic core business has been quite stable as has the non-Hispanic international group.
The wild card is on Hispanic churn rates, can we -- can the actions we put in place help us meaningfully? Are there other wild cards that might come in the marketplace that could create some upside pressure to churn? On the whole, we think that you should be thinking about roughly stable churn throughout the year with certainly improvements in the back half of the year relative to the front half. Sorry for the long-winded answer, but I'm sure it but it is on everybody's minds, and I wanted to give as much color as we could.
Michael Rollins - Analyst
That is very helpful, thanks. Then on the margin potential, about $100 million?
Barry Rowan - CFO and CAO
Yes, let me speak to that. So let me start with the revenues we do see as having that potential through a combination of the strategic growth initiatives between both the mobile services business as well as expansion outside of the US. So, since we've just introduced the Vonage Mobile product, let me talk about that margin potential and how we think about it.
First is that we have very low termination rates, as you know, which enables us to be able to price at the levels that we've described. We have priced this for penetration. The real objective here is to build a community because that is really when you get the revenue potential to start to grow. Once you get that community built, people start making those off-net calls, which is the primary source of revenue in the early stages. So, with our low cost in termination, we have been able to price this in a way that gives us good incremental contribution margins in the range of our current core business. So, over time, what we will have to monitor is how the market evolves. As I mentioned, it is priced to be able to drive downloads. We will continue to evolve the business model over time as we look, for example, at various alternatives for payments and the like. But the strategy is to be able to price it down, to drive penetration, to make acceptable an attractive contribution margins and then we will evolve that over time as we see the overall use base grow.

Great, thanks. Just to follow-up for one more moment. I apologize for asking so many questions. But, just in terms of -- you guys obviously, do a lot of evaluation of the incremental investment relative to the incremental returns. It seems like the story for Vonage over the last couple of years has been about looking to develop this optionality that you have to move into new markets, while harvesting the cash out of the home replacement business.
If I have that right, and it seems like now you are willing to take some of that home replacement cash and really get more aggressive for these new sources of growth. So, as we're trying to evaluate returns for that, is there a way to think about maybe the rate of return you should get from that, over a five-year period or just the ability to generate long-term margins, where you are today or better? Any further thoughts on that would be just incredibly helpful, thanks.
Marc Lefar - CEO
So, Mike let me take the front end of that in terms of framing and how to think about what we have been doing or where we are going. You are largely correct in stating that we have, over the last couple of years, had to get to a point where we had the stability and the cash flow that gave us this optionality to begin to invest. We thought the time was right, we had the organizational capacity, the products, and understood the markets. It wasn't that long ago when we didn't have even the flexibility of debt covenants to be able to rise very far away from a very specific set of financial metrics that had very high pain thresholds if we were to miss any numbers.
We've now been able to generate tremendous cash. We've been able to stabilize the business. Barry talked about the pristine balance sheet, and now we've also -- while doing that been able to understand better these markets, build some of the products and services that you see in Vonage Mobile, which were not capabilities we had 18 months ago. Now, that we are much closer to the ability to start really selling and marketing these and managing with the interfaces for partners. Whether it be distribution partners, whether it be partnerships internationally, or whether it be to accelerate the speed with which we actually bring new products and services in mobile to market, we now have the ability to invest prudently to drive these revenues.
In terms of overall return, I'll let Barry comment in terms of our internal targets over five year what IRR we're targeting, but that is exactly the way we're thinking about the business. Get to this point, generate cash, know that we can continue to generate cash and be able to afford an investment in those things that we think have strong return and leverage our technology and our organizational skills.
Barry Rowan - CFO and CAO
Let me just build on that a minute, Mike. You used the word harvesting. I would not use that word, I think when you've got the core business to the point where it's driving stable cash flows. We view this as an appropriate use of a portion of that cash to really drive the growth. Now, as Marc described, we've developed with the conviction plans around these growth initiatives. So, as you know, this is not a change in direction at all. In fact, it is really a continuation of the direction, but a deepening and an increase -- a deepening of the conviction in and an increase of the investment now that we have that conviction.
So, as we have laid plans for this during the course of this year, and put the business models in place, we certainly are going to bring a prudent measured financially disciplined approach to the way we evaluate these opportunities. So, we would look, for example, at around a 20% IRR threshold for projects. That's been case as we look at these opportunities. We've talked a lot about mobile, and we also say that on the international expansion alternative, that is going to be done as we've described on a more case-by-case partner-by-partner type basis. So, we will look at each of those projects and opportunities as we develop a very detailed cash flow model and set of projections around that, that are designed to meet those internal thresholds.
Michael Rollins - Analyst
That's really helpful.
Marc Lefar - CEO
Let me add one more point on the guidance. Again, we're pretty straight shooters and try to give the transparency that we can and also where you don't have it, we won't. I think on the guidance, we wanted to communicate to folks at the start of this year that we believe the time for investment and accelerating in investment it really is now. We have enough visibility in the products and service and the opportunities that we don't want to surprise somebody later in the year. It is not a guarantee that it will be $5 million to $10 million, or that it is consistent through the quarter during the course of the year. We are providing a range of estimates because we need the flexibility. If you think about our total marketing spend and total size of our business, $5 million to $10 million a quarter is not a lot when you think about starting businesses of this magnitude.
So, we wanted to share with you the range, lay that on the table and trust that we are going to execute each one of those projects and each one of those investments and evaluate them individually. It is not a right of communication that the money will be spent, it's us trying to share with you the range of investment that we think will be required. We're going to do that very opportunistically, and if something catches fire we're going to feed it. If something isn't working particularly well, we're going to cut it back. That's the way we've operated the last three years, but now we're going to do that with a broader range against driving revenues.

Next question, Operator?
Operator
Our next question comes from Mike Latimore with Northland Capital. Please go ahead with your question.
Michael Latimore - Analyst
In terms of that $100 million view, how would you divide that among the three growth initiatives that you have here? Would you say that you're going to get $33 million from roughly each of those three growth areas, or is one going to be the predominant key for that $100 million. Then, which of the three growth areas do you think will be the most impactful this year?
Barry Rowan - CFO and CAO
Mike, I think it is too early to provide those. We wanted to give a sense of guidance for what we thought the overall opportunities could result in. The way we would describe them are generally in order of priority and sequencing as we laid out, so really the mobile services opportunity is a very large market. We have a product that is out of the gate now. We are very pleased with those initial results. So clearly that, as a platform and extensions of that platform is going to be a very important thrust of where we go and probably certainly the highest priority at this point in terms of time.
The second priority is on the international and geographic expansion. We are active in discussions about that. As we talked about, that will depend on the nature of the relationships that we develop, because we do see that as primarily coming through business partnerships. But those markets are very large and some of those potential opportunities are large. So, I think that is going to be -- the characteristics that of that growth are going to be different, because they are going to be based more on a project-by-project basis versus the mobile opportunity. That is really driven by the overall market opportunity and the position we are in to be able to compress the pricing in the industry historically, and with our -- leveraging our technology platform.
Then the third area, is continuing to drive the penetration into ILD colors and the US. We do see that as an opportunity, but that is a more mature market, and we continue to tune up the marketing spend to drive that. But that is the order of priority we put them in internally, as they unfold.
Michael Latimore - Analyst
Great, and then on the new mobile app, it sounds like the downloads are going well. Do you have a sense or a goal as to what percent of the downloads will be paying users versus free users?
Barry Rowan - CFO and CAO
We do. We have a robust model on that, and we've looked at what are general industry norms along these lines. So, you have downloads. Obviously that translate into a number of active users, and in our case that then translates into the number of people that are actually monetizing it based on off-net calling. So, as is typical in the industry, it's a small percentage ultimately going all the way from downloads to monetized calls. But really the early results are positive actually, that active users are ahead of expectations. It is too early to see how the monetization results are going to unfold, but we are very pleased with how that is unfolding at this point relative to the model we have in mind.
Marc Lefar - CEO
Over the next few months, Mike, the goal in this model is, you've got a build large communities. You've got to give folks who are active users, using the free services that are then pulling through those additional revenue streams. By the way, the additional revenue streams, we've talked about it them as the international calling and texting. But there is also opportunities if you get the right size of base, particularly if they are heavily using chat and SMS, to develop advertising models as well as a wealth of information created based upon a large-scale community that can be monetized potentially as well.
So, I think the key metrics we're focused on right now are downloads, and folks who are actually engaging with the product, and inviting others to join, and having those contacts. That is where we go to first and foremost. If you do that well, then the revenues will follow.
Michael Latimore - Analyst
Okay, and then on the reintroduction of annual contracts, is there a -- is there going to be some ARPU trade off there? How should we think about ARPU versus the move back to annual.
Marc Lefar - CEO
No, there won't be an ARPU trade off with the return to service agreements. The way we are structuring this is, previously everybody got our promotion du jour. Now, the way we're going to structure this is, much like the wireless industry in terms of device subsidies. If you want to get the promotional pricing, you'll take a 12-month service agreement, and if you simply want to pay the full boat $26 per month, then you don't have to take that contract.
Net-net, withholding any other potential ARPU compressors or competitive stuff, that would technically give you something of a more ARPU increase, because you wouldn't spend more of that promotion. We are not forecasting that but mathematically, that's what you can conclude. It is just a function of taking existing promotions and those would require service agreements. It really returns to where we were before, but still gives people choice so that those who simply don't want to be locked into a contract do have an alternative with us.

Next question operator?
Operator
(Operator Instructions) Our next question comes from Robert Routh with Phoenix Partner Group.
Robert Routh - Analyst
Just two quick ones. First, I noticed, clearly you guys reversed your NOL, which you didn't think you would ever be able to use, and that tells me that you obviously see sustained profitability from a pretax point of view for GAAP in the foreseeable future. I'm just wondering if I'm reading into that right. If you can tell us, obviously how much clarity did you have in order to take the step of reversing that NOL and actually putting it back on the books and being able to utilize it?
Then second question is, obviously you spoke about your return on capital and you're looking for a 20% IRR. Looking at your stock down today 15%, and given your balance sheet which is solid as a rock, the free cash flow expectations, the growth. Even though you had diminutive loss of subscribers for the year given your sub base, it would seem the best use of your cash now would clearly be your own stock. Because your cost of equity has got to be over 50%. Yet with your debt so low for a Company that could be levered two times at almost a zero interest rate environment, I'm just wondering whether Management would consider at some point instituting some share buyback. It would seem as though, in addition to your other initiatives, that would be a really good use of your cash, as well as send a good signal to your major shareholders that you believe your stock is cheap at current levels?
Marc Lefar - CEO
Let me take your first question first. Relative to the NOLs, you've got that exactly right. It does -- it requires a very significant analysis both by management, the board, internal audit -- I'm sorry, external auditing firm, as well as other experts to determine what is the probability that you will be able to use those before expiration. The measure is, degree of confidence that you will in fact do that. So, it does reflect, as you rightly pointed out, confidence in sustained profitability. So, that is a very bullish action to take that and put that as a deferred tax asset on the balance sheet. Barry, do you want to take the other one?
Barry Rowan - CFO and CAO
Yes, so that is absolutely the case, and you can't do that and make this investment that is an accounting entry without taking, of course, a very careful look at that. That gets a lot of scrutiny, so we really did that. It is certainly an indication of our confidence there.
Regarding the use of cash and would we reconsider a stock buyback, the answer is yes. As we think about the use of cash, and we've talked about this in the past, clearly as we -- even with the investments that we are planning on making to drive growth, we do plan to continue to build cash during the course of 2012 albeit more modestly than if we had not been making these investments. So, we are paying for growth out of the operating earnings of the Company. We will also continue to evaluate opportunities for inorganic growth that would make sense, but at the right time we would also consider returning capital to shareholders at an appropriate time in the future. So, as we've talked about in the past, being in this position of having a reasonably sizable cash position of $59 million at the end of this quarter for example, is new to Vonage. But as things unfold, that is certainly something that we will do and actively discuss with our Board. It is something that we would consider doing at the right time.
Robert Routh - Analyst
Great, and just a follow-up to the first answer. Is there any -- if you were on our side of the fence as we are looking at the Company, how would you quantify the cash value of taking those NOLs and now you have the benefit of them whereas wouldn't before? What you think is a fair tax rate to apply to that number to get to the incremental equity value that you've created by being able to do that?
Barry Rowan - CFO and CAO
I think the best way to look at that is, if you look at the entry that was put on the balance sheet, so the deferred tax assets are in the -- $326 million. So, that is in fact the NOLs that we haven't placed that we believe are more likely than not, which is the test, to be used before they expire. We take those NOLs and apply the effective tax rate. So, that is the expected cash savings from those NOLs at the prevailing tax rate,$326 million. Then to get the present value that you have to discount it back obviously, based on the expected usage over time.
Robert Routh - Analyst
Sure, great. Thank you very much.
Leslie Arena - Director, IR
Okay, Operator, we have time for one more question, please.
Operator
Our final question comes from Brian Horey with Aurealian Management.
Brian Horey - Analyst
I actually have three. Just a follow-up on the last question, do you have a target leverage ratio in mind for the business, because it looks like you will be either completely debt free or in a net cash position before the end of the year. Do you have any thoughts about philosophically what the right level of leverage is?
Barry Rowan - CFO and CAO
Our strategy on that, Brian, is to pay down the debt according to the current schedule. As you know, historically we had prepaid debt when we had interest rates up in the 9% to 10% range. At these current interest levels, it does not make sense in our view to prepay them, so the plan would be to pay that down according to schedule, and that debt gets paid off in the middle of 2014. The strategy there is to be able to maintain debt capacity if not using it for things that would make sense in the future. So, the strategy is to maintain that level of debt for the foreseeable future but have that capacity available as appropriate for future uses.
Brian Horey - Analyst
Okay, and then on the mobile app that was just introduced. Do you have a range of ARPU number there that you think is realistic to achieve once you get the community built?
Barry Rowan - CFO and CAO
We do have expectation for that. When you look at where the market is, it is in the sub $10 range, but that's what you see is typical. For example, not to -- if you were to go to Skype, that's one, for example, and you see that. But what we look at is something in that a zip code.
Brian Horey - Analyst
Okay, that is fair. Then lastly, with the three growth initiatives that you've discussed during the call, can you give us any sense as to what transparency or visibility you're going to offer on the -- either the gross or profitability or both of those three efforts over the course of the year.
Barry Rowan - CFO and CAO
We recognize the need for visibility into that, so we will describe those in ways that make sense as they unfold. For example the number of downloads that Marc described for the mobile app is the best early indication of how that is taking hold. In terms of profitability and [growth], we will have to just let this unfold. Obviously, it's going to take some time for this to be material. We've described the -- in response to the previous questions, our approach to that which is to make sure that the new businesses in the case of mobile and the new specific opportunities achieve a targeted internal threshold. So, that is certainly what we're achieving, and we will give additional information on those revenues as they materialize over time.
Marc Lefar - CEO
Let me just clarify. So, we will provide tactical indicators of progress, but we do not plan to do segment-specific reporting until it becomes material to the business. You should not expect that in the next couple of quarters. So, we'll keep you posted on progress. You can assess how we're performing, but the level of detail of individual line item metrics and segment-traditional reporting that you might expect in something that was 30% or 40% of our business, we don't foresee that in the next couple of quarters, and I wouldn't want to set an expectation that you will see that.
Brian Horey - Analyst
Okay, I understand.
Leslie Arena - Director, IR
With that we will conclude the call. Thank you for joining us today.
