Frank Addante
Thank you, Bonnie, and good afternoon, everyone. I'm excited to welcome Michael Barrett joining David and me on today's call.
Michael's joining us as our new CEO this week. I will speak more about the context that led to our decision to ask Michael to join the team.
But before I talk about the state of the business, I would like to say that we are pleased that our financial results in Q4 came in within the range of outlook that we provided last quarter.
Frank Addante
Our fourth quarter wrapped up a difficult but highly productive year for Rubicon Projects, as the team faced multiple challenges throughout the year and met them head-on, enabling us to further expand our platform. In addition to the success we have seen in mobile, video and orders, we are now beginning to see very promising results in header bidding.
The difficult decisions and changes we made in 2016 have resulted in the company reinvigorated with focus. We now have all of our resources, capital and attention committed to our most important business, the ad exchange.
Frank Addante
Over the past couple of quarters, we've gone through a lot of effort to restructure the company so we can successfully transition our platform to best serve the ad exchange. This includes our accelerated product introduction of FastLane, our organizational changes and our decision to divest the intent marketing business.
Frank Addante
To move forward in the right direction and return to revenue growth, we must continue to build strong relationships with publishers and application developers, operate at scale and continue our transition to build technologies required in a mobile-first world. With that, I'm excited to have Michael Barrett joining us as CEO.
Frank Addante
Michael and I are very aligned on vision, and he's a perfect cultural fit for the company, which is why I decided to approach Michael about joining Rubicon Project as our CEO. I've known Michael for 10 years, he's a proven advertising executive and a strong -- has a strong personal brand with customers.
He deeply understands our space and demands of our customers, having worked as Chief Revenue Officer at Yahoo! and FOX.
As CEO, he successfully led a supply side platform, AdMeld, that competed directly with Rubicon Project for years, before he sold it to Google. He continued on with Google's advertising business and then joined Millennial Media, a mobile-only market place, as CEO, which was later acquired by Verizon AOL.
And now, Michael Barrett is joining Rubicon Project as CEO to own and lead the operations and execution of our business strategy as we focus on continuing to grow Rubicon Project as the largest independent global exchange for advertising.
Frank Addante
I will continue to be a very active, engaged and passionate Chairman. The best way I can see -- serve our team, shareholders and our mission is by having the bandwidth to look forward and guide our future and by paving a path to the future through thought leadership and evangelizing our vision.
Michael's arrival will enable this additional bandwidth and I'm excited to partner with him and Tom Kershaw, our CTO, to execute against Rubicon Project's strategic, operational and product roadmap.
Frank Addante
Before we talk about the success we've had with our strategic growth areas, I'd like to start by sharing why we remain confident that the strength of our global exchange, premium marketplace and strong balance sheet uniquely position us to win. In a $600 billion global ad market, there continues to be a tremendous opportunity for an independent global exchange.
Our customers need the technology and scale that Rubicon Project offers to compete with the walled gardens and to offer consumers a better advertising experience. Rubicon Project continues to be well-positioned strategically as the independent and inherently neutral global exchange.
Our strategy for growth has always been to attract the most supply or impressions from the world's top publishers and application developers to our marketplace. And that is why, in 2017, we will be focusing our efforts on increasing market share of supply, signing up more publishers, application developers and getting as much inventory into our exchange as possible, which we believe will result in revenue growth in the future.
Frank Addante
As we continue through 2017, we plan to invest in engineering technologies and deploying our sales resources in strategic growth areas of mobile, video and orders. We plan to continue to optimize our algorithms for header bidding to capture and monetize as much supply as possible.
We believe that there's an immediate window of opportunity to accelerate our market share capture of supply.
Frank Addante
Therefore, we also plan to continue to evolve and optimize our business and pricing models to focus, first, on accelerating market share capture of supply, and then, growing revenue. We are a marketplace business driven by marketplace network effects.
Losing access to supply from header bidding was a significant factor that stunted our growth in 2016. We've made great progress in solving the problems, access to supply.
We have now grown the number of ad requests, that is supply, to our exchange by more than 50% from last year.
Frank Addante
Investing in market share capture of supply this year is our #1 priority, and we believe that this will lead to revenue growth, just as it has in the past.
Frank Addante
We will also continue to prioritize investments in our proprietary cloud computing infrastructure, which not only gives us a competitive edge by driving better performance for our customers, but also becomes a competitive differentiator and a competitive barrier. Our investments in our own cloud enable us to bring on more bidders, creating more demand and more differentiated ad spend.
We're also able to operate our platform incredibly efficiently. You've seen this through the leverage in our business in the past that has driven our profit.
And going forward, we plan to continue to leverage this further to capture more market share profitably.
Frank Addante
Our smaller competitors will have a tough time competing with our infrastructure, scale and efficiency.
Frank Addante
Now let's talk about the business drivers, specifically around the dynamics of a global exchange and what drives growth. Supply creates gravity for demand, and we've seen this strategy work again and again over the last 10 years.
Every product Rubicon Project launched has followed this model of beginning with supply. This is why it's so important that we focus on capturing market share supply this year, setting the stage for our return to revenue growth in the future.
Frank Addante
Let me give you some examples as to how this strategy has worked successfully in the past. In our first 3 years, Rubicon Project's ad network optimization technology grew to more than 500 customers and billions of impressions by focusing on signing publishers and gaining access to supply of ad impressions first.
RTP then grew from 0 in 2011 to $620 million of cumulative revenue through 2016, again, focusing on market share capture of supply first. Orders, which were pioneered in 2014, has a 71% GAAP revenue CAGR since we achieved critical mass of supply.
In mobile, in 2015 and 2016 alone, represented more than -- I'm sorry, almost $600 million in ad spend, growing faster since its launch than RTB did over that similar period of time.
Frank Addante
Video continues to grow with more than half of our top 100 customers using our ad exchange for video, and the ad spend is following. And in 2016, FastLane has grown from 0 to more than $120 million of advertising spend in just over 3 quarters with more than 300 deployments.
All of these strategies were successful by focusing on capturing market share access to supply first, with revenue growth coming over time. Even our name, Rubicon Project, originated from this strategy.
We figuratively crossed the river when we started by focusing on publishers and supply of ad impressions.
Frank Addante
While just about every other company in the advertising business has focused on the advertisers, we crossed the river to focus on publishers and gaining access to supply. To this end, we're making great progress on market share capture of supply.
Consider that in 2016, we increased the number of impressions available on our global exchange by 50% year-over-year. We sold or up sold more than 400 new customer deals.
And in Q4 alone, we processed approximately 45 trillion transactions, all this while continuing to maintain a strong balance sheet with nearly $200 million in cash today, enabling us to strategically invest for growth.
Frank Addante
As I said at the beginning of this call, I remain very excited by the advertising industry and by Rubicon Project's future growth potential. The value of an independent global exchange cannot be overstated, and we look forward to the next phase of growth.
Frank Addante
I've been super appreciative and proud to serve our team as CEO for the past 10 years. I love this company and I'm proud to continue to serve our team and shareholders as Chairman and Founder.
With that, I'd like to turn over to Michael to say a few words before we get into the financials.
Michael Barrett
Thank you, Frank. I'm very excited to be joining Rubicon Project and to work alongside you and the terrific team that you have built.
As Frank noted in his comments, I've had the opportunity to compete against Rubicon Project as well as be a customer, and have always been very impressed with the professionalism and industry leadership that you've shown over the years. So when Frank approached me, I was excited by the opportunity, and I'm delighted to be a member of this team.
Michael Barrett
The advertising space, particularly the programmatic piece, continues to grow, both in size and importance to buyers and sellers. Rubicon Project is well-positioned to capitalize on these trends.
Yes, the industry is dynamic, and this reality can lead to disruption. Frank has spoken in the past about the challenges and opportunities that innovations like header bidding brings for Rubicon Project.
I look forward to working with our customers and team to make sure we are delivering the best possible product and monetization capabilities going forward.
Michael Barrett
Rubicon Project has a strong leadership position, a strong balance sheet and an aggressive and innovative product strategy. We are well-positioned to become the leading independent global exchange for publishers, application developers and advertisers.
I'll be heads-down for the next few months meeting with customers and our team. Soon after, I look forward to meeting with all of you.
Again, thank you, Frank, and the rest of the board for this opportunity.
Michael Barrett
David will now give an update on the company's financials.
David Day
Thanks, Michael, and welcome to the team. I'd like to start by saying that we're grateful for Frank's pioneering vision over the last 10 years, which has led Rubicon Project to the position in the industry that we enjoy today.
I look forward to Frank's continuing involvement with the company, and I'm excited to work together with Michael.
David Day
For the full year of 2016, we generated over $1 billion in advertising spend, $278.2 million in GAAP revenue, $256.1 million in non-GAAP net revenue, $70.9 million in adjusted EBITDA, and $1.07 per share in non-GAAP EPS.
David Day
We executed well against our revised goals for the fourth quarter, which took into account the continued year-over-year decline in desktop advertising. Advertising spend for the fourth quarter of 2016 was $277.1 million.
GAAP revenue for the fourth quarter was $72.7 million, and non-GAAP net revenue for the fourth quarter was $66.9 million. The decline in advertising spend of 18% year-over-year during the fourth quarter of 2016 was driven primarily by a continued decline in desktop, which declined 23% year-over-year to $178.2 million.
We also experienced a decline of 5% year-over-year in total mobile advertising spend to $98.9 million. This is a result of declines in our mobile Web business, which still represents the majority of our total mobile business, in contrast to our mobile app business, where we expect more promising growth in the future.
Advertising spend was composed of 36% mobile and 64% desktop for the fourth quarter of 2016, compared to 31% mobile and 69% desktop a year ago, reflecting our continued shift towards mobile.
David Day
While we've historically shared additional advertising spend detail for real-time bidding and orders, we will no longer be sharing those details for a couple of reasons. From a product perspective, we are focused on developing additional products for our buyers that will further allow them to discover and transact based on extended audiences across our platform on a guaranteed basis.
As these products emerge, orders and RTB distinctions will become less relevant. In addition, continuing to provide this information would also require us to provide associated revenue detail and could expose sensitive pricing strategies to our competitors.
David Day
Non-GAAP net revenue for the fourth quarter declined 20% year-over-year or slightly more than advertising spend due to lower take rates, which are defined as non-GAAP net revenue divided by total advertising spend. Take rates decreased 80 basis points to 24.1% in the fourth quarter of 2016 from the year-ago period, and also decreased 80 basis points on a sequential quarter basis from the third quarter.
Take rate decreased primarily due to an increase in the overall mix of ad spend through orders, which has a lower take rate than RTB. Additionally, take rate declined due to ad spend mix shift towards FastLane and Exchange API, which carried lower RTB take rates than our traditional business due to auction dynamics and pricing strategies related to those APIs.
We also began testing various pricing strategies in the fourth quarter, which had an impact on take rates.
David Day
Our fourth quarter advertising spend and revenue results include results from our static solution, which we exited in the third quarter of 2016, and from our intent marketing solution, which we exited in the first quarter of 2017. To assist understanding our results in the context of our ongoing activities, we are also providing, as adjusted, advertising spend, revenue and take rate as though the static and intent marketing solutions were discontinued at the beginning of calendar year 2015.
Note also that intent marketing was the only component of our revenue reported on a gross basis. Thus, GAAP revenue and non-GAAP net revenue are the same after excluding these solutions on an as-adjusted basis and will be the same in the future.
Therefore, on an as-adjusted basis, for the fourth quarter of 2016, advertising spend would've been $266 million, and GAAP revenue would've been $62.4 million. For the full year 2016, advertising spend would've been $955.1 million, and GAAP revenue would've been $234.6 million, and take rate would've been 23.5% in the fourth quarter of 2016, compared to 25% for the same period in 2015, and compared to 24.4% in the third quarter of 2016.
David Day
Operating expenses for the fourth quarter of 2016 were $94.6 million. Note that these expenses included a $23.5 million noncash impairment charge on intangible assets related to customer relationships and developed technology, which was caused by our exit from our intent marketing activities, and a $3.3 million restructuring charge related to our workforce reduction in the fourth quarter.
Excluding these 2 effects from impairment and restructuring, operating expenses for the fourth quarter of 2016 would've decreased year-over-year by $8 million or 11%.
David Day
On an adjusted EBITDA basis, operating expenses for the fourth quarter were $45.2 million, a decrease of $2.6 million compared to the fourth quarter of 2015, reflecting savings associated with lower headcount driven by cost management initiatives, including our workforce reduction in November. Note that the operating expenses and our adjusted EBITDA calculation include the $3.3 million in restructuring costs mentioned earlier.
David Day
Net loss was $21.2 million in the fourth quarter of 2016 compared to net income of $20.4 million in the fourth quarter of 2015. The change in net income was driven primarily by the noncash impairment charge associated with our intent marketing exit of $23.5 million, and the $3.3 million restructuring charge and by lower net revenue, partially offset by other reduced operating expenses.
David Day
Adjusted EBITDA was $21.7 million in the fourth quarter of 2016, representing a year-over-year decrease of $14.3 million. Note that we exclude the $23.5 million noncash impairment charge associated with our intent marketing exit, but we do not exclude the $3.3 million in restructuring costs mentioned earlier in our adjusted EBITDA calculation.
The decrease in adjusted EBITDA was driven primarily by decreases in revenue mentioned earlier, partially offset by lower costs.
David Day
Diluted GAAP loss per share was $0.44 for the fourth quarter of 2016, compared to diluted GAAP income per share of $0.43 in the same period in 2015. Non-GAAP earnings per share in the fourth quarter of 2016 was $0.37 compared to $0.74 reported for the same period in 2015.
These amounts included estimated tax impact based on the expense items reconciling between net income and non-GAAP net income. We have not previously included any estimated tax impact, and thus, have now adjusted historical amounts to also reflect an estimated tax impact for consistency.
David Day
Capital expenditures, including purchases of property and equipment as well as capitalized internally used software development costs were $14.5 million for the fourth quarter of 2016, and $33.4 million for the full year 2016. We closed the period with $190 million in cash and marketable securities, down $3.2 million from September 30, 2016.
Free cash flow was a negative $3.2 million during the fourth quarter of 2016, and a positive $26.7 million during the full year 2016. We calculate free cash flow as net cash provided by operating activities less capital expenditures, including capitalized software development costs.
David Day
As we migrate from our traditional reliance on desktop display towards our growth initiatives, including mobile, video, orders, header bidding and other emerging opportunities, we expect we will continue to experience uncertainty with respect to the timing and financial impact of these initiatives. Accordingly, we will provide guidance for the first quarter of 2017.
However, we are not providing specific guidance for the full year 2017 at this time. In addition, we do not expect to provide quarterly guidance in subsequent quarters.
For the first quarter of 2017, we expect the following
GAAP revenue to be between $41 million and $45 million; non-GAAP net revenue to be between $41 million and $44 million; adjusted EBITDA to be between negative $6 million and negative $4 million. Note that this range includes the impact of nonrecurring costs of approximately $5 million associated with the exit from our intent marketing solution and with our executive management restructuring; non-GAAP EPS to be between negative $0.26 and negative $0.22 per share based on approximately 48 million forecasted weighted average shares, and roughly $6 million in CapEx spend.
For the first quarter of 2017, we expect the following
This guidance includes intent marketing GAAP revenue of approximately $1.5 million and non-GAAP net revenue of approximately $500,000 during the first quarter of 2017. Directionally, for the remainder of 2017, we anticipate that take rates may decline sequentially at a rate similar or greater than what was seen during the fourth quarter of 2016, driven by factors discussed previously that we will realize efficiencies and operating expenses driven by our previous restructuring activities and ongoing cost management measures such that adjusted EBITDA operating expenses may grow only marginally on a sequential quarter basis after adjusting for our first quarter restructuring costs, and the CapEx spend levels may be similar to 2016.
For the first quarter of 2017, we expect the following
As we look forward, we remain optimistic about our long-term growth prospects. We occupy a strategic position in a dynamic and growing global marketplace.
And with the appointment of Michael Barrett as CEO, have further strengthened our already strong management and technical team. We will continue to prudently manage our financial resources and to protect our balance sheet while making the right investments to position us well for longer-term success.
Frank Addante
Thank you, David. I spoke earlier about why I feel -- why we feel positive about our product innovation and our execution in capturing market share of supply, both key drivers for our future success.
While it's clear we still have some work to do to get this optimism reflected in the financials, we believe that by building on the strong positions we have in mobile, video and orders, and continuing the accelerated progress we're making in FastLane, we will emerge as the leading independent global exchange.
Frank Addante
Before opening up for questions, I wanted to reiterate my excitement that Michael is joining our team. He's a proven leader and has the operational experience and strong customer brand.
We're lucky to have him onboard. With that, we'll now open up the call for questions.
Operator
[Operator Instructions] And our first questioner today is going to be Kerry Rice with Needham.
Kerry Rice
Maybe, first, a question on the header bidding or FastLane. What is the best way to best understand the penetration of FastLane?
Is that the number of publishers, which, I think, you mentioned around 300 deployments out of, I think, roughly 500? Or is it maybe the percentage of impressions that you can sell?
If you can give any more details around that, that would be great. And then, the second question is really around mobile.
You mentioned that mobile came down, that was primarily the mobile Web, which I assume, again, is in relation to kind of header bidding. When do you think about mobile app revenue being the primary or the majority of mobile revenue?
Frank Addante
Kerry, it's Frank here. So the best way to understand the penetration of header bidding, so first, just to kind of set the context of this, header bidding is not an entirely new platform for us.
It's an API. It's another way to integrate into the existing customer base as well as new customers.
So we have 1,300 customers overall. We have 300 deployments now with header bidding.
The first stage is to sign the customer, then we've got to get it implemented. Then we've got to get it tuned and make sure that, that implementation integration is clean and operating efficiently.
And then, from there, we've got to make sure that the algorithms are optimized for that particular site. And so, then, your revenue growth expands there.
So if you look through the numbers, we've got 300 of our existing 1,300 customers, so there's a lot of room to grow from there. That's not including new customer opportunities, by the way.
Even within that existing customer base, we estimate that about half of those or -- are tuned and fully efficient deployment, so even within those deployments that we have, there's some room for growth there as well. So we're pretty excited, obviously, about the prospects of it.
And what really kind of drives that revenue growth, given that we're a marketplace business, is the access, as I mentioned, to supply. I mean, header bidding is ad requests, and those ad requests overall in our platform grew 50% on a year-over-year basis, even though we had a challenging 2016 year.
Reconnecting that supply is critical for us in reconnecting that revenue growth, so we're feeling pretty good about that supply reconnection, even within the deployments that we have.
Kerry Rice
Frank, can I maybe just follow up there briefly. When I think about 300 versus 1,300 total customers, is it the intent, or is it the plan to all 1,300 should use the implementation of FastLane?
And so, if so, how do we think about that progression of the other 1,000 deployments?
Frank Addante
Yes. It's a great question.
So look, our platform is designed to integrate with the publishers or app developers in any way they would like to integrate. So in some cases, we have multiple integrations.
So sometimes, it's FastLane and our traditional Smart Tag business and our orders business. And sometimes, they'll also integrate our mobile business through SDKs.
So sometimes, within that existing customer base, there's multiple integration points. We don't necessarily expect that every single one of them are going to implement header bidding.
It's really the customer's choice. Yet, header bidding is -- it's grown more in North America, for example.
It's grown more obviously in desktop. As you're moving to things like mobile app, yes, there's some nuances that changed there.
And also, with our orders product, some customers just use our orders products, in which case, header bidding could be helpful, it certainly is, but not necessarily required. I mean, also, our xAPI products as well is a different type of integration point.
It's basically server-to-server integration point. So while there's a lot of opportunity in that existing customer base, it doesn't -- we don't have to implement it with every single one of our customers to go reconnect that supply.
Kerry Rice
Okay. Then on the mobile Web versus mobile app inflection point?
David Day
Mobile Web does continue to constitute a majority of our spend, so we see that, I guess, a couple of different dynamics there. First, as we make better progress on our header bidding, that will stabilize the mobile Web side of the equation.
On the mobile app side, we certainly continue to -- it's still a growth area for us. We have a product roadmap that will provide -- using our xAPI API, will provide a much greater access without having to have the SDK implementation.
And so we think, from a product perspective, we're building that out. We've got significant momentum there.
The timing of when that turns is just hard to say. As I mentioned on the call, it's just challenging right now with visibility, but we're certainly headed in the right direction.
Frank Addante
Yes. We're making some good progress there already.
One of the reasons that we're excited to bring Michael onboard is -- his most recent gig was CEO of Millennia Media, a mobile-only marketplace. So he's got a lot of experience in that area, and I think that's going to be really helpful to accelerating, hopefully, our efforts in that area.
Operator
The next questioner today is Andrew Bruckner with RBC Capital Markets.
Andrew Bruckner
Two, if I could. The first one, Frank, last quarter, you talked about the strategic market position as being a key question.
I'm wondering if you've thought about that any differently over the past quarter, and if you think any sort of M&A or inorganic components are necessary. And then, secondarily, if you've disclosed any economics on the Tapad cross-device partnership?
And if these are any capabilities that you could eventually have in-house versus having a partnership?
Frank Addante
Yes, absolutely. So from a strategic market position, we're pretty bullish.
I mean, if you look at header bidding, which is obviously an area that caused some challenges for us in the desktop display market last year, again, an area that we were less focused on because we had shifted our attention and resources to mobile, video and orders, which was where the market's heading. If you take that, right, so if you take something that was a challenge for us, and if you look at the rate that we've been able to turn that around from a customer implementation standpoint and a product implementation standpoint, you're pretty much coming from a cold start.
We launched a product in the market, you get 300 deployments. 100 -- you go from 0 to $120 million of ad spend in just over 3 quarters.
I think that illustrates the strength of our market position. It illustrates the strength of our customer relationships, and I think, it illustrates the -- not only the need, but the importance for a platform like ours to have strength of being desktop, mobile, video, orders, all those things in one place.
Our global reach of demand is a critical factor there as well. If you look at our cloud computing infrastructure, our ability to bring on hundreds of bidders onto that, not only bring differentiated demand, but also creates more competition in the auction.
So when we deploy something like header bidding, or mobile, or video or orders, we see that, that market share capture of supply rapidly increases because we're able to leverage that differentiated demand, that scale, our existing customer base. So we feel pretty good about that, even though with the header bidding piece, had created a little bit of hiccup for us.
Our ability to kind of turn that around so quickly, I think, makes us more bullish about our ability to continue to deploy new products in the market in the future.
Andrew Bruckner
And with respect to Tapad, do you think there's any sort of capabilities you'll ever have in-house?
Frank Addante
Yes. The Tapad partnership, it's too new to communicate any of the economics.
For cross-device, we'll want to support any device graph that has buyer adoption and can grow ad spend for our customers, which could include proprietary and external solutions.
Operator
The next questioner today is Brian Fitzgerald with Jefferies.
John Streppa
This is John on for Brian. Just wanted to touch back on take rate for a little bit.
In your as-adjusted numbers, you had take rate coming down to about 23.5% this quarter. Just curious what your thoughts are on kind of the long term take rate that you think this business can manage as you move to some of these other products such as FastLane?
And then, just another follow-up on header bidding. Anything that you're seeing there from the client demand side on video and any implementation that you're looking to kind of roll out over '17 there, that would be great.
David Day
Great. On the take rate front, certainly, as we've mentioned before in the sort of short and medium-term, we do see continuing decreases.
As mentioned, we expect that on a sequential basis, we should decline equal to, or perhaps greater than, what we've seen the last few quarters. From a long-term perspective, it's very challenging because there is just such a significant mix of different types of channels that we run through.
So it will certainly decrease. And we don't really have the visibility at this point to know where that ends up, and so we'll play out this year and see where that leads us.
Frank Addante
And on your header bidding for video question. So we're pretty excited about the opportunity there, particularly combined with our orders platform because, now, header bidding enables us to gain access to the most premium supplier impressions of the publisher.
So if you connect that to our orders products where you've got higher CPM, more valuable deals occurring there, it opens up a new opportunity for us in video that didn't exist, just even a year ago.
Operator
The next questioner today is Jason Helfstein with Oppenheimer.
Alec Brondolo
This is Alec filling in for Jason. You noted during your prepared remarks that you were going to look to leverage the $200-or-so million in cash on your balance sheet in your quest to reaccelerate growth.
But the company was cash flow positive in 2016, so could you just maybe give us a little bit more color on how you're planning to use that cash?
David Day
Sure. Well, let me start with we're very committed to protecting our balance sheet.
And so I'm not sure that we talked about significant initiatives using our cash, but we're very committed in protecting our balance sheet. At the same time, we do want to make sure that we make the appropriate investments in our products, our go-to-market strategies.
We want to make the investments in our serving costs, for example, for ad requests, which we think can be a great competitive advantage over time. And so as we play out this year, one of the advantages that we do have is that strong balance sheet, and so we can continue to make those important investments even amidst some of this uncertainty and some of the challenging visibility.
So we don't plan on expending significant amounts of cash but we have that in reserve in case that dynamic between our decreasing spend on our legacy desktop display doesn't stabilize as soon as we hope compared with the growth of our investment opportunities.
Frank Addante
Andrew had a question before about M&A, and I think I might be getting, too. So we've grown this business organically and inorganically in the past.
We've done 7 acquisitions now, both as a private and public company. We acquired a company a long time ago from Fox, which became the foundation of our cloud, which was pretty critical for RTB.
We acquired a data and security company that was again very important for us to build a premium marketplace. We acquired 2 companies for orders.
And clearly, we're seeing some great success with that. I mean, also, the foundation for mobile, while it was a small acquisition, it was a pretty significant acquisition, and we've built a tremendous business now in mobile from that.
So the bar for us is really high, both from an engineering perspective and a people perspective, but if there are opportunities for us to advance our roadmap and better serve our customers, and if it makes financial and strategic sense, it's nice to have a strong balance sheet to evaluate those opportunities.

The next questioner today is Matthew Thornton with SunTrust.
Matthew Thornton
Welcome aboard, Michael. I guess, maybe one for Frank, and one for David.
Frank, you guys gave some good color on the take rate side of things. I guess, on the volume side of things, have you seen any precedent where, perhaps, your share was waning on a client, but as you've got FastLane and header bidding kind of implemented, and perhaps, maybe some of the video and mobile products kind of implemented where you've actually seen that share start to inflect and come back?
I'm just curious if you've seen any precedent there? And then, similarly, when you think about clients, I guess, is client growth, still positive?
Is the client count is still growing? And then, just secondly, for David, the cost rationalization program, I think, in total, was about $30 million annualized.
Are we at that full run rate as we exit 1Q? Or is there still work to be done into 2Q?
Any color there would be helpful.
Frank Addante
Matthew, so look, I think, you nailed one of the most critical things that we saw in 2016 that we're seeing quickly turn around here from a supply perspective. So this is not necessarily the best analogy, but I'll give it a try.
So pretend that there was a big storm in Manhattan, and let's say that Uber had all the Uber drivers in New Jersey, and let's say that, that storm cut off the bridge, so those Uber drivers couldn't get into Manhattan, right? So that's basically effectively cutting off the supply.
Uber is not going to be able to generate revenue because there's a lack of supply of drivers that are in Manhattan, right? It doesn't mean that, that revenue is lost forever, but it can't monetize something if that supply access is not there, right?
So what happened in North America desktop display with us in 2016 is that some of that supply was cut off and wasn't able to make its way to our platform. It's as though somebody poked a hole in a pipeline, and that oil wasn't actually able to get to our system.
Once we deployed our own FastLane solution and as we're making those integrations, making sure that those integrations are clean and efficient and working well, we've reconnected that supply. Some of the stuff that we gave were -- we've seen now a 50%, 5-0, 50% increase in ad requests or impression access on a year-over-year basis, which has grown pretty rapidly.
300 new deployments, obviously, in header bidding that we just talked about, but 400 new deals overall. So to answer your question about client deals and client activity, new deals are being signed all the time.
One critical point to make there is that because we're a marketplace business, as the supply in the past was -- or some of that supply was cut off, it took a while for that revenue decline to lag. And now, as it's being reconnected, it's got to, first, be made available in our marketplace, and then, it's available again for the bidders to bid on, and then, those marketplace effects start to reverse.
David Day
Great. Matthew, regarding the cost control initiatives, a vast majority of those initiatives and their impact will be complete by the end of this quarter.
And so if you look at our Q1 expense run rate and normalize for the roughly $5 million in one-time or nonrecurring costs, that will give you a pretty good baseline for the rest of the year.
Frank Addante
Sorry, 2 additional stats on your previous question. So in terms of client growth, the number of sellers, publishers and application developers grew by 172 on a year-over-year basis.
And then, FastLane accounts who have header bidding installed, we're seeing 3x now the number of ad requests per account, per month, versus our traditional Smart Tag business, and that's why we're pretty excited about the growth prospects in the future, especially when you combine that with our orders platform where we're now accessing inventory, especially the most premium inventory that we weren't able to see before.
Matthew Thornton
That's really helpful. Maybe just one quick follow-up, housekeeping for David if I could.
I think, you've talked about tax rate a little bit. How should we be thinking about tax rates this year?
And if you could just give us an update on the NOL balance, that would be very helpful.
David Day
Sure. We still have a significant portion of NOLs.
And so from that perspective, we should have de minimis taxes, at least for the short and medium-term. The NOL balance for federal is, I think, $38 million.

Our next questioner is Sameet Sinha with B. Riley.
Sameet Sinha
I want to start with a question for Mike. Mike, you've been at big companies, small companies, and you decided to join Rubicon.
Are you -- the question is, in this ecosystem where we -- the larger companies are taking most of the share, what do you see in Rubicon that got you attracted to joining the company? And then, I have a couple of follow-ups for Frank and David.
Michael Barrett
Yes. Thanks, Sameet.
Well, to me, I have been in this space for as long as I have, and being as close to the clients and customers, a continual refrain that you hear from them is a desired alternative to just the big guys who, in many times, are in varied [ph] competition with them, they're either outselling advertising. And if you're a buyer on our exchange, that's direct competition.
And on the other hand, if they own inventory, they're outselling their own inventory and our publishers and application developers fight against that. And so the idea of this global, at scale, independent exchange resonates incredibly well with the customers and is more topical now than it ever has been.
So that, to me, is the biggest driver. Obviously, I know the guys at Rubicon well.
I've known Frank for years, respect the leadership, respect the team, really respect the product and the innovation that's coming downstream and just thought it was a perfect opportunity, both from a marketplace and from a company specifics to join Rubicon at this point.
Sameet Sinha
Okay. Secondly, Frank, if you can just talk about header bidding.
Obviously, you spoke about the deployments. And what do you still think from a technology perspective?
Is that still a good technology? I mean, we hear about header bidding challenges, whether it's data center or server capacity that kind of soaks up all other challenges regarding fraud or even viruses.
That's one question. And then, if you can also talk about just in terms of you've mentioned lack of visibility a couple of times, and that's going to be the reason for removing guidance going forward after the first quarter, but if you talk about the business about getting supply back, making more deeper penetration to current clients, would it not be helpful having broad guidance out there, so that we out here who have less visibility than you do can at least track the business as we go along?
Frank Addante
Yes. Sameet, so header bidding from a tech perspective, so header bidding is a technology that clearly needs to operate at massive, massive scale.
It's putting a lot of pressure on the DSPs as well. So making header bidding work and making it scale are 2 different things, and the latter is a much more complicated challenge than the former.
So from a tech perspective, the client-side implementations, the technology that was initially used in the market, it was pretty primitive. There are some open-source technologies that we've embraced, and see us being able to take that and add onto it, a lot of the investments that have made us really successful in the past, things like our security technologies, our brand protection, safety.
Things that have really enabled us to attract the most premium publishers in the world and create a safe marketplace and environment for the most important brands, advertiser brands in the world to buy. Those are the things that drove not only our success in the market to date, but also made programmatic and automation and real-time bidding, something that was not only a reality, but something that could be trusted within the entire industry.
DSPs, agencies, advertisers, publishers themselves, et cetera. So us being able to bring those technologies into header bidding certainly make header bidding not only safer, more robust, but it gives us a differentiator, but hopefully will also solve a few bigger problems for the entire market, which will hopefully grow the market as a whole, which is something that we've always been very focused on.
In terms of your data centers, serving capacities, I've talked about this in the past. We made investments from day 1 of this company to create a super highly efficient infrastructure.
We knew that as an exchange, we're going to process massive amounts of volume at, relatively speaking, low margins, just given the nature of our business. So we made sure that we can process things incredibly efficiently.
That served as well. We made some acquisitions in the past, as I mentioned before, to bolster that.
And we continue to make investments in the cloud. And that's not only enabled us to scale but to do so profitably in the past, and it gives us the ability to capture market share on a global basis.
And looking forward, I think that's going to be a critical point, not only to our success to continue to scale. I think, it's going to become a critical point for us to help the DSPs who are getting hammered by a lot of these ad requests across the board.
And I think, it's going to become something that not only becomes a differentiator for us, but a barrier to entry for smaller competitors because it's going to be really difficult to scale and make money at the same time doing this, and us having our proprietary cloud infrastructure is going to be very, very critical for us to do that and, I think, something that's going to be tough to replicate.
David Day
And Sameet, regarding visibility, certainly recognize what a challenge it is for analysts and investors to not have broader guidance from us. We have tried to share directionally some things that we think have some visibility into with regard to take rate declines.
Certainly, from a cost perspective, holding those steady and CapEx levels. Beyond that, I guess, a couple of things, we certainly are committed to protecting our balance sheet, and so we will be mindful, as this year plays out, how that pacing and how that growth develops.
And we'll be mindful of our cash burn. We are in the position to utilize some of that cash, as mentioned, to make the most important investments, which we will do.
But we'll monitor that carefully, and we'll play out this year and try to directionally provide information where we can.
Frank Addante
Yes. And some additional color to that as well.
Look, as I said multiple times in my script, our #1 priority this year is capturing market share of supply and try to illustrate how that's been a successful strategy for us in the past. So if we need to balance or sacrifice some short-term revenue to bolster that strategic position based on history, that's a smart thing for us to do.
And we just want to make sure that we leave ourselves some room and flexibility to make sure that we're truly optimizing for that, and then we're making sure that both our business model and pricing models are reflecting our ability to capture market share and make sure that this company is best positioned strategically. We think that's a smart thing to do, and we want to make sure that we are leaving ourselves some room to do that versus trying to tie ourselves to some kind of strict guidance, at least in the short-term.

The next questioner today is Jason Kreyer with Craig-Hallum.
Jason Kreyer
Michael, welcome to the call. Frank, you mentioned several times, and just piggybacking on the last comment, the effort to capture additional supply as you move forward as a marketplace-focused business, how does that sale change trying to capture supply going forward from here versus your success capturing supply in the RTB business, capturing supply in the orders business?
How does that shift from here on out?
Frank Addante
The strategy is actually pretty similar. When we first launched our very first product, ad network optimization, similar strategy with real-time bidding, similar strategy with mobile, video, orders, and similar with the header bidding.
We first go to our existing customer base. It -- I don't want to say it's an easy add-on, but it's an easier add-on because we say, "Look, you already have desktop and mobile.
Hey, why don't you turn on this additional feature on as well?" We're also -- having the position to be able to leverage existing buyers, whether that be DSPs or advertisers and agencies that are using our orders product.
So first, it's about going to our existing customer base. Sometimes, we're able to use new products to enter into new customers that aren't using existing products as an entry point, so for example, when we just had real-time bidding, we introduced orders into the market, some of the most premium brands in the world where they may be a little sensitive to auctioning their inventory, so we were able to enter with the orders product.
They get comfortable with that, we establish a relationship with them, and then we're able to then go back and upsell them the real-time bidding product, or now the FastLane product, et cetera. So it's -- having multiple -- having a portfolio of multiple products helps us to either leverage existing customers or bring new products to new customers and then continue to upsell them.
Jason Kreyer
Okay. And then, the Q1 guidance implies more significant deceleration.
And just wondering if you can walk through the factors that are impacting Q1 more strongly than what has impacted Q4?
David Day
I think, it's just -- it's a continued deceleration of our legacy mobile desktop display. And the growth areas while we're encouraged by the momentum that we have there, they are not -- we haven't hit that tipping point quite yet, and that's also the foundation for some of the lack of visibility that we have going forward this year as it regards guidance.
And Frank, I don't know if there's anything you want to add to that.
Frank Addante
I think, just another comment on the guidance pieces. We have a new CEO that's joining here.
So giving him the opportunity to come in, take a look around, really dig in, galvanize some of our strategies. I think, it's a fair thing to do to give him some space and time to do that.
Operator
The next questioner today is Mark Kelley with Citigroup.
Mark Kelley
Two quick ones. The first one, you talked about that 50% growth in ad requests in your prepared remarks.
I just want to clarify, is that a 4Q '16 over '15 number, or is that full year? And then, second, any thoughts on the SoundCloud partnership?
I know it's very, very early, but anything you could provide there would be very helpful.
Frank Addante
Yes, the 50% increase in impressions was full year. For SoundCloud, so it's not launched yet, so too early to give any specific comments around that.
Mark Kelley
All right, fair. And then, one more if I could.
Last quarter, you called out a lot of smaller solutions that maybe gained some traction, header bidding early on, and that caused some of the disruption. Has the shift to server-side header bidding happened?
Obviously, scale will matter. Are you seeing some of the smaller guys already go away?
Or do you think it'll take something like server-side to make that happen?
Frank Addante
Yes. Look, go away is probably not a term that's used in ad tech very much.
There's always ebbs and flows. Look, we've been at this now for 10 years.
There's a reason that there's only a handful of exchanges and only a couple of really large ones, us being one of them. The shift to server-side, look, we have a server-side product, our xAPI, we've been in the market with this for, I think, it's 1.5 years now with our cloud competing infrastructure.
We are certainly extremely well-positioned there. So I think, we're pretty bullish if that's the way the market goes.
I mean, part of that is effectively what we've been doing for 10 years. So with that said, there are some challenges in server-to-server header bidding.
Without getting into too much detail, there's some cookie translation issues where you might become difficult for some of the buyers to be able to do some of their retargeting or some of their just general targeting and things like that. So we're excited if the market goes there, we're prime positioned for it.
Again, we've been in market with a server-to-server product, our xAPI. In terms of what that does to smaller solutions, it's hard to tell exactly without their smaller solutions, but we've clearly made a lot of progress with our own FastLane header bidding solution, just even on the client side.
With that 50% increase in ad impressions here overall, the 300 deployments, you have to imagine that we are doing some damage to those smaller competitors, but it's a huge market, it's a $600 billion market, there's plenty of dollars to go around. I think, we're more focused on trying to grow the market for everybody versus trying to necessarily do away with any particular smaller competitor.

Looks like we have no further questions, so this will conclude our question-and-answer session and also today's conference call. Thank you, all, for attending today's presentation and you may now disconnect your lines.
