Thank you, Laura. Hello, everyone. This is William. Thank you for joining us on today's call. I'm very pleased to report another quarter of outstanding performance with significant progress across our business. Let's start with sales, which is a leading indicator of our future revenue and profit growth. In the third quarter, we signed up customers for nearly 19,000 sq m of net additional area committed. All of this is organic. All of this is in Tier 1 markets. With this addition, we stayed on track to double the new business we signed last year. At the same time, we delivered to our customers around 14,000 sq m of additional revenue-generating space. The utilization rate moved up to 68%. This drove another quarter in which our adjusted EBITDA grew by well over 20% quarter-over-quarter and 100% year-over-year.
Backing this up, we started the construction of four new projects and brought another four into service on time and within budget. We kept sales and the capacity growth synchronized. The pre-commitment rate for areas under construction was 45% based on signed contracts, with significant more in the constructing process. As always, we ensured that all of our projects are fully financed with sufficient equity and long-term project debt. Overall, this performance demonstrates the resilience of our business and our ability to keep on beating targets. We are once again raising our 2018 guidance for revenue and EBITDA. Turning to slide four. A highlight of our sales achievement for this quarter was three significant new customers wins, namely JD.com, Kingsoft, and NetEase.
This was a direct result of our targeting of large-scale cloud and internet customers who we believe are strategically important for our franchise because of their cloud platforms, valuable data, and ecosystems. On the enterprise side, we won our largest ever order from a foreign financial institution, a top U.S. bank, which is moving fast to capitalize on the financial services liberalization in China. Usually in this quarter, new customers accounted for over 50% of our new business. This demonstrates that we keep diversifying our top customer base. At the same time, this does not mean our existing customers are pulling back. Based on what we see in our sales pipeline and what our top customers have shared with us, we don't see any let-up in the current level of demand.
There is a lot of debate pointing to a slowdown in parts of the digital economy as a result of macroeconomic and geopolitical factors. How is this affecting us? The short answer is that we don't see it. I think there are three main reasons to explain the apparent disconnect. First of all, our business is geared towards the growth of cloud platforms. As everyone knows, public cloud in China is still at an early stage of development. The I segment is just 15% of the U.S., but forecast to grow at nearly double the CAGR over the next five years. Alibaba, the market leader, has just reported 19% year-on-year revenue growth for its cloud business, which is similar to our growth rate. Furthermore, our largest customers still have a long way to go to migrate all their own IT onto their cloud platform.
This internal demand is not reflected in the disclosed revenue figures. The second reason is new technology, in particular, AI. More and more applications are become AI-enabled. It's a major focus area for Chinese tech leaders. They expect to create a lot of economic value from AI over the next few years. From a technical perspective, AI requirements more data, more storage, and more computation. Many AI applications are also highly latency sensitive. This is increasing demand for data centers like ours in Tier 1 markets. The third reason is that our largest scale customers secure their supply of data center resource based on 12 to 24 months planning time horizon. The capacity to fulfill their requirements does not exist. It has to be built.
Therefore, our customers need to contract with us now in order to ensure that they will be able to execute their business plans in 2019 and 2020. This is why we have a large backlog and high visibility for future growth. In summary, we remain highly confident about the sales outlook based on our existing and the new customer relationships and the evolving technology. Let's turning to slide six. I have talked about demand. Now let me talk about supply. There are many changes to creating new resource supply in Tier 1 market due to the pressure on real estate and power. As scale increases, these challenges are only getting bigger. The ability to deal with these challenges is one of the factors which sets GDS apart. As we initiate new projects, we consistently restock our resource pipeline.
In addition to what you see currently under construction, we have another 100,000 sq m plus of capacity held for future development. Our ability to maintain continuous supply in all Tier 1 markets is a critical consideration for hyper-scale customers. No other service provider in China comes close to us in terms of data center platform. This is why we don't see any significant change in the competitive intensity. Going forward, we are evaluating campus-type developments on the edge of the Tier 1 markets to industrialize our capacity expansion, making it easier and more efficient for us to scale up. We are also actively considering entering one or two new Tier 1 markets. We expect to make announcements about such projects over the next couple of quarters. We have a great track record of delivering resource to customers for the expansion.
Although we don't talk about it very often, we also have a great track record of delivering exceptional operating performance. We were recently put to an extreme test. During September, Southern China was struck by the worst typhoon in 100 years. Sure, on slide eight, we had eight self-developed data centers in the eye of the storm. Despite over 500 failures in the power grid and the damages to other critical infrastructure in the Shenzhen and Guangzhou regions, our data centers ran non-stop without any breach of SLAs. This is the kind of achievement which our customers really recognize and appreciate. With that, I will hand over to Dan for the financial and operating review.
Thank you, William. Starting on slide 13, where we strip out the contribution from equipment sales and the effect of FX changes. On a quarter-over-quarter basis, our service revenue grew by 20.2%. Our underlying adjusted NOI grew by 26.2%, and our underlying adjusted EBITDA grew by 29.4%. Our underlying adjusted EBITDA margin increased by 2.7 percentage points to 38%. Our reported adjusted EBITDA margin was 39.5%, a 3.1 percentage point increase quarter-over-quarter, and an eight percentage point increase year-over-year. Turning to slide 14. The main driver of revenue growth was the increase in area utilized, with around 20,000 sq m added in the second quarter, and a further 14,000 sq m in the third quarter. Our contracts with large-scale customers typically provide flexibility for how fast they move in. This gives us a bottom line in terms of delivery schedule, and upside if customer move-in accelerates.
The outperformance in the second and third quarters reflects faster than expected move-in. This might surprise you considering reports from the tech supply chain, but it just goes to show that our experience does not necessarily correlate with what they are seeing. Monthly service revenue, or MSR per square meter, in 3Q18 declined slightly from the previous quarter. However, if we exclude the impact of the three Hebei projects which came into service around mid-year, the MSR actually increased. An MSR of RMB 2,759 per square meter, excluding Hebei, is 2.5% below the average for the preceding 12 quarters. As we grow, our key objective is to sustain a return on investment, as measured by unlevered post-tax IRR, in the mid-teens. The MSR is a rough approximation for the average selling price or ASP.
When it comes to measuring returns, we must also look at what is happening to development and operating costs. I'll come to this in a moment. As shown on slide 15, profit margins are on an upward trend. The growth drag at the adjusted NOI level, which we saw in the past few quarters, has now reversed. For this quarter, the margin expansion mainly came from the leverage on data center level fixed costs as a result of higher utilization. As shown on slide 16, our data centers area and service is now over 50% stabilized, compared with 47% in 2Q18. The increase in the stabilized proportion contributed to the margin improvement. At the corporate level, on slide 17, SG&A is 10.9% of service revenue. Going forward, we expect to achieve significant further leverage on our corporate overheads.
Factoring in full delivery of the backlog, we can already see that the current level of SG&A is down to 6% of service revenue. Turning to CapEx on slide 18. In 3Q18, our CapEx paid was around RMB 1.1 billion, including RMB 111 million related to acquisition consideration. For the year to date, our cumulative CapEx paid was around RMB 3 billion. Most of the cost of the Hong Kong real estate acquisition will appear in 4Q18 CapEx. As you can see from the breakdown of CapEx incurred, it will cost an estimated RMB 2.6 billion or $380 million U.S. to complete all the projects which we have currently in service and under construction. This would get us to a total of 191,000 square meters of fully fitted and equipped capacity.
For the projects under construction, the estimated CapEx per square meter is around RMB 60,000 or $8,800 U.S. per square meter at current exchange rates, which indicates how we have been lowering costs and maintaining our returns at target levels. Turning to slide 19. During 3Q18, our net debt increased from RMB 7.2 billion to RMB 8.8 billion. Part of the increase was due to the capital leases for the SH9 and BJ6 properties, and part was due to the settlement of CapEx payables. Our net debt to last quarter annualized adjusted EBITDA ratio decreased from 7.8 times to 7.3 times. However, in 4Q18, with the payment for Hong Kong, we expect it to rise again. Our effective interest cost was 6.1%. Most of our existing loans are project finance at the data center level.
These facilities are structured in a conservative way, matching the debt service to the project cash flows over a five-year period. Typically, once the data center is stabilized, the project debt to data center EBITDA multiple is around three times. With a high level of pre-commitment in the form of six to 10-year contracts with investment grade counterparties, the ability to service this debt over the project life cycle is assured. Once projects are stabilized, our practice is to refinance on a longer-term basis. This means that we always have a lot of project finance going on. In 3Q18, we completed four project finance transactions for a total facility amount of RMB 792 million. Currently, we have another five project financings ongoing for a total facility amount of RMB 2.9 billion, out of which RMB 808 million is refinancing.
The China banking market is currently very liquid and very receptive to our business. The benchmark rates for determining our interest costs are stable. In fact, they have not changed for three years. This gives us a high degree of confidence in our ability to continue project financing and refinancing to the extent required. Every project which we have announced to date is fully funded with equity and debt. This means that we are fully funded to the level of 191,000 square meters of move-in ready space. In addition to this, we still have capital available for allocation to new projects, which we will announce in the future. We are confident of our ability to leverage this capital in the same way as we have always done.
With a combination of available capital and leverage capacity, we estimate that we could build out a further 50,000 square meters on top of the existing 191,000 square meters in service and under construction. Turning to slide 20. As at the end of 3Q18, our backlog had increased again to over 61,000 square meters. We currently have around 100,000 square meters, which is revenue generating. The backlog implies that we can increase the revenue generation space by 60% without signing any new customer contracts. Given the operating leverage, this should translate into more than 60% EBITDA growth from the level of 3Q18, based purely on what is already contracted. Finally, on page 21. Our 3Q18 results clearly show that we are tracking ahead of expectations in terms of revenue and adjusted EBITDA growth. The accelerated move-in has brought forward new service revenue that we expected to commence later.
Given where we are today, we are further raising our guidance for FY18 revenue and adjusted EBITDA to not less than RMB 2.75 billion and RMB 1.02 billion respectively. The new numbers imply year-on-year growth of over 70% for revenue and over 99% for adjusted EBITDA, in both cases exceeding the year-on-year growth rate we achieved in FY17. At the same time, we are maintaining our FY18 CapEx guidance of RMB 4 billion unchanged. With that, I will end the formal part of my presentation, and we would now like to open the call to questions. Operator?
Yes. Thank you. We will now begin the question and answer session. If you wish to ask a question, please press star one on your telephone and wait for your name to be announced. If you wish to cancel a request, please press pound or hash. Once again, it's star one for questions. Our first question comes in line of Jonathan Atkin from RBC. Please ask your question.
Thank you very much. I was interested, I guess a question for William or for Dan. As you look at potentially acquiring projects that are underway by smaller developers, what does the pipeline look for sort of small tuck-in M&A? And then a couple of questions that came to mind from your slide deck. Slide 16 gives information about the stabilized asset pool, and I wondered if you could tell us what the margins are for that set of stabilized assets. And then lastly, on slide 18, you talk about your construction program. Just under half of the area is pre-committed. Three of the projects that you list there are 100% pre-committed. And as we think about the non pre-committed sites in Beijing and Shanghai, are those likely to fill with one single customer, or would you potentially fill that with multiple logos? Thanks.
You want to acquisitions?
Yeah.
Yeah.
Yeah. Hello, John. This is William. I think what we see in the market, what happened is, and we think that there's a lot there, acquisition opportunity in the market. We select a deal very carefully. We have more top pipeline than before, but that let us can select, use a very high standard to select the target acquisition deal. We still in the early stage to evaluate. There's a lot of the project right now. Dan, you want to add some more color?
Well, just on the other two questions that John asked. The margin for the stabilized part of the portfolio, the stabilized part of the area in service, it fluctuates. In the third quarter, it was over 55%. About the projects, if I understood correctly, the projects which are under construction, but not yet pre-committed. I think we provided some information about when those projects will come into service. If we just look at the two projects that will come into service in the first half of next year, which are not yet pre-committed. One of them, Beijing Four, for now, or from inception, we position that for enterprise and financial institution customers who typically don't pre-lease. We may begin to take commitments three months before it comes into service.
I said for now, because there is some pressure from large scale customer, we may reposition, reallocate that capacity. We'll make a decision in the near future. The other data center, which is due to come into service in the first half 2019, which is not yet pre-committed, is phase three of what we call our Shenzhen Five data center. It's a very huge building, relatively centrally located in Shenzhen, is highly marketable. Right now it's a toss-up as to whether it goes to an existing customer in that building or whether we are free to offer it to other customers. Either way, that's very nice resource to have on our hands. Does that answer your question, John?
John, I want to add on some.
Yeah.
I want to add on a little bit on the M&A deal. Number 1, currently what we see in the pipeline is much stronger than before, that not say we would take action immediately. This allow us have more opportunity to get a deal. Our strategy is still keep on organic growth. That's our priority.
Thank you. That does answer the questions. Just lastly, given the strong demand and the desire to grow, including potentially in a new tier 1 market, how do you think about your various financing options to fund this expansion?
Yes, John. There's debt and there's equity. Right now, the position in terms of the banking markets in China, as I said in the prepared remarks, is very favorable to us. Partly as a policy response to what is happening, the Chinese government has reduced reserve asset requirements, I think, four times for Chinese banks. That's made it easier for us to obtain the project debt that we require. Not that we are having any problem, but I think it just gives us the ability to say that the leverage will be there with a very high degree of confidence. On the equity side, fortunately, earlier this year, we did a couple of capital raisings, and that put us in a relatively strong position, going into this current situation.
I outlined the amount of capacity that we could build just using our existing capital, and you can assume that's either organic or it's a combination of organic and acquisition. The total of what I said came to around 240,000 sq m. Up until now, we've always raised the equity capital we need at the holding company level. We are always continuously approached by investors who are seeking to partner with us at the project level. That's something we keep an open mind about. I think it's something really that I'd like you in the market to take away, that we're not beholden to the public equity market to raise the capital that we need. It's simply a question of looking at what our options are and what is the lowest cost of equity capital available to us at the time when we need it.
Thank you.
Thank you. Our next question comes line of Robert Gutman from Guggenheim Partners. Please ask your question.
Hi. Thanks for taking my question. Can you just talk about the trend in accelerated move-ins? It looks like the part of the beat and the clues, the Chengdu site that was delivered early, I believe that was 94% pre-leased. What's the outlook for the accelerated pace of move-in timing as we roll through the next few quarters?
Hi, Rob. It's Dan here. Yeah, it's a curious one, isn't it? Because it happened at a time when all the indications from the tech supply chain is that the opposite should be happening, right? It wasn't one customer in one place. If you really drill down into the details in the appendix to our earnings presentation, you'll see that there's, I think, seven or eight data centers, which came into service at the beginning of this year, which were already somewhere between around 50%-80% utilized, occupied, which is very rapid by anyone's standards. Why is this? There's a variety of reasons, because it's not one customer and it's not one place. Some of it is related to new products, some of it is related to some promotional activities. Of course, a lot of it is just correlated with the growth of the cloud.
Going forward, maybe it's too early to say. We get delivery notices from our customers. They give us around three months plus notice of their move-in intentions. We can forecast around that. Beyond that timeframe, we tend to forecast based on what it says in the customer contract. There's a bottom line, a delivery schedule, we call it minimum contractual commitment in the customer contract. That underwrites whatever guidance or forecasts that we make. For now, I won't change our usual practice. I will leave it to kind of upside, and pleasant outcome if indeed the customers move in faster.
That's great. Thank you.
Thank you. Our next question, comes line of Gokul Hariharan from J.P. Morgan. Please ask your question.
Yeah, hi. Thanks for taking my question. First of all, Dan, could you elaborate a little bit more on your comments about the operating leverage that could start to kick in, just going into the next year or so? I think you started talking about SG&A coming down to about 10%, 11% level and potentially could be even lower. Second, could you talk a little bit also about what are your rough CapEx expectations given the pipeline of demand that you're seeing, as well as the entry into potentially one more new tier 1 market? If we leave the M&A aspect aside, which I think you're waiting on timing, et cetera, the right timing. From organic basis, could you talk a little bit about what could be the kind of CapEx that we should be thinking about?
Is the number that you're spending this year roughly the kind of ballpark that we should be thinking? One last question, a quick one is, could you talk a little bit about the Hebei project economics now that at least one of the data centers is pretty much stabilized? Are NOI margins in Hebei quite high compared to the normal data center operations given the ASP and the utility cost pass through structure is different? Thanks.
Like I could've guessed you were going to ask those questions. We talk about the operating leverage at two levels, at the data center level and at the corporate overhead level. At the data center level, it does tend to fluctuate. We brought a lot of capacity into service late last year and early this year, then that had a result of actually reducing or lowering our NOI margin. As we've gone through the year, the utilization rate has increased by, I think, three or four percentage points. The proportion of our area in service, which is stabilized, has also increased by three percentage points. That's what's raised the adjusted NOI. I have to say, when I look over the next three or four quarters, it's not going to go up in a straight line.
However, leverage on the corporate overheads, I think that can be a very significant feature over the course of next year. We talked about this before. We have a lot of corporate overhead, which is related to growth in terms of sales and marketing, project sourcing, design, procurement, construction management, and of course, funding, as well as some pre-operating costs, which are included in G&A. Those costs don't really need to scale. We're still operating in the five tier 1 cities. It may increase by one or two, but we're not going all over the map. I do think that we expect to achieve quite significant operating leverage on corporate overheads over the next year. In terms of capital expenditures, if you calculate, we've been disclosing cost to date and cost to complete for our in-service and under-construction capacity.
If you look at the under-construction capacity and you calculate the total cost, you'll see it comes to less than RMB 60,000, which in current exchange rates is under $9,000. That's clearly lower than what we've talked about in the last couple of years, and it's an indication of the initiatives that we've taken around supply chain management and scale economics coming through. When we look at the CapEx for next year, although it's too early for me to give guidance, I think I can go on record and say that it's not going to be materially higher than this year's number. It'll be higher, but not materially higher. As regards Hebei, in total, it's three data centers, which represent less than 10% of our total area committed. I don't want to call out too much about those three data centers. Otherwise, it's going to overcomplicate.
You are right, the revenue per square meter is lower than our average. The data center level margin or NOI margin is higher, and the project return is at the low end of our range. Because of the build to suit customer contract, we were able to finance these projects with a lower overall cost of capital. The spread over our cost of capital was actually quite attractive. I've disclosed just for the third quarter and the second quarter what the revenue per square meter, MSR per square meter would have been without the Hebei projects. If I look at the NOI margin or EBITDA margin, the impact of those projects was not very significant in those two quarters.
Okay. Got it. Thank you. Thanks, Dan.
Thank you. Our next question comes from Frank Louthan from Raymond James. Please ask a question.
Great. Thank you. Can you talk to us a little bit about the EBITDA margins? It's been a nice uptick. Where do you think those can ultimately go to? Remind us kind of what the margins are on the stabilized properties. Just as a follow-up, and I apologize if you've mentioned this earlier, but what is the current status of any deals that you've sourced from the CyrusOne relationship, and when do you expect to see some projects from that? Thanks.
Okay. Frank, hi, it's Dan here. I'll go first on the EBITDA margins. I know what you and Gokul others are getting at. You want to know how quickly our EBITDA margins are going to go up. The first target that we'd like to, or threshold that we'd like to cross, is 40%. Incidentally, we IPO'd just two years ago, just over two years ago. We just had a two-year anniversary. At that time, we targeted to reach 40% EBITDA margin at the end of 2018. I think you can see that we're on track to achieve that despite the fact that we're growing. Our growth is two to three times what we expected at the time of the IPO, which also implies a very significant growth track that we had not factored in. I think it's a good achievement for us to have got here.
If you look at the stabilized part of the portfolio, I mentioned in the third quarter, at the NOI level, it was over 55%. When you add in the part that is not stabilized, which is ramping up, it brings the total down to 48.5%. That won't go up very quickly. That was Gokul's earlier question. It will go up and down. It will trend up, but it won't go up very quickly. You have to deduct from that the SG&A, which is currently over 10%, but which will come down, I think, to the lowest levels you've seen for any U.S. data center service provider, and maybe less. I think maybe that gives you some indication of where the EBITDA margin will go to over the next one to two years.
Okay, great. On any CyrusOne benefits that you may be able to give?
Yeah. I think so far we still cook some deal right now. What we see is that currently the China government opened the door and let a lot of the financial institution and other, let's say, multinational company coming. What we see, we are working very closely with CyrusOne to try to catch up with this, select a set, a couple of their segment and vertical to which the company has the high intention to come to China right now. I think that given the time, we will have the result. I'm very confident for that. Okay, great. Thank you.
Thank you. Our next question comes line of Colby Synesael from Cowen and Company. Please ask the question.
Great. Thank you. Just a few. First off, just in light of where the stock's gone and your continuing needs to finance. Just trying to get a sense of what comfort level you have on leverage, and where that could potentially go over the near to medium term. Secondly, I think when we look at the macro, there's obviously a lag in terms of data centers, in terms of how people are purchasing those types of services from companies like yours. I think the concern is that as we start to see, potentially, a slowdown in 2018 as we go into 2019, we're not going to see that show up in your leasing results perhaps for another year or so.
Because a lot of the projects, to your point, that you're signing now and likely will sign for the next few quarters are from deals that you've been working on for perhaps a year or two at this point. What comfort level do you have that those trends, as we go into 2019, can be sustained? Based on what your own observations are of the underlying businesses of your customers. Just my last one. You mentioned in your prepared remarks, you're looking at potential edge expansions in some of the current Tier 1 markets that you're already in, looking to potentially industrialize how you go about building data centers. I was wondering if you could just give us a little bit more color on what that actually means and what the potential financial impact to your business could be, perhaps over the next year or two. Thank you.
William will go first on the. Let me explain a little bit about the next year's outlook. A lot of people say, "Oh, maybe a little bit, the server shipment goes down." This is not a direct affect us what I just explained, because a couple of reasons. Number 1, we have the right customer. Our customer, the business which we host actually is very early stage in China. They all grow in a very significant way. Based on my latest stage conversation with all the business unit heads from our key customers, they all talk to me. There's nothing changed in next year. This is number 1. This is a very bottom-up conversation in the last four weeks. This is number 1.
Number 2, I would say, based on our sales pipeline, I can tell to maintain this year's levels sales booking in next year. I'm fully confident because we already had 2.5 times of the pipeline coverage of our target. We are just finish our sales plan in next year. I'm very confident to maintain this year's level, new booking in next year. On the other hand, as I just talked in my presentation, I say we keep add on new large-scale customer in our customer list. This is quite diversified our customer base. All the Chinese unicorn and we still have the long-term exist in years, which haven't been our customer yet. We are confident to add more customer like JD.com, NetEase, and Kingsoft in the next few quarter. Okay, let me talk about a little bit of campus type development.
Number one, I think currently the environment is a lot of the local governments now they change their attitude. A lot of the edge town of the Tier 1 city, they keep pursue us, try to invite GDS to buy some land or lock up some resource and then make some future investment in their area. They offer more better deal than before, and they are eager to get GDS name in their new investment list. Now that GDS have the position to have a stronger position to get the better deal, best deal in the future. We are still evaluating right now. This is number one. That means future, we try to build our land bank in the future. It's a little bit early to talk about, to inject the capital right now.
We try to maximum squeeze the landlord and the local governments, and we try to get the maximum condition for us. I think it's a good time to get into this A project right now. We will have a bunch of way to get the best deal, and currently it's not directly affects our equity right now. On the other hand, we learn a lot from CyrusOne, which they have the track record to build up a hyperscale campus type data center. A lot of the new technology like VR structure, a lot of the prefabrication type data center scale, we learn a lot from them. This is the meaning when we talked about industrialize the future data center to fulfill the hyperscale customer. Standardize our design.
Okay. Colby's first question about how we think about leverage. The main focus is actually on the leverage at the project level. We inject equity into individual data center project companies, and then leverage it with project debt. Typically, it's 60% debt, 40% equity, and then once the data center is stabilized, that translates into around 3x debt to EBITDA. If you look at the disclosure, you look at the data centers which are in service, you'll see many of them have lease rates or commitment rates of 95%-100%. In fact, I think 17 have commitment rates of between 99% and 100%. The customers, the counterparties behind these commitments are almost entirely investment grade, very well-known companies, and they are entering into 6 to 10, I would say mostly 8 to 10 year contracts with us.
Significant portion of those contracts don't have a right of early termination. They all have very severe penalties, and I think only once in our history has a customer terminated. We look at the cash flow that can come from those contracts over multiple years relative to the amount of cash required to service the project debt, and it's covered multiple times. We feel that the way our projects are financed is actually very conservative. However, when you add it all up, we have stabilized data centers, we have ramping up data centers, we have data centers under construction. There's debt drawn down for data centers that have not yet reached optimum level of EBITDA. There's debt drawn down for data centers which are pre-operational and have no EBITDA. It's the aggregate of all that which you see reflected in our consolidated net debt to EBITDA multiple.
Interestingly, as of now, we don't have a single financing facility with a consolidated net debt to EBITDA multiple covenant in it. Nonetheless, appreciate that equity investors tend to focus on that metric, even though it may not be all that meaningful. We would like over time for that metric to come down to the kind of levels you see in the U.S. However, for now, with the very significant growth opportunity which we have in front of us, I expect that multiple will stay at the kind of levels it's been now and in the last few quarters, which is to say seven to eight times, maybe closer to eight times.
Great. Thank you very much.
Thank you. Our last question comes line of Colin McCallum from Credit Suisse. Please ask your question.
Thanks very much. I'll just keep it short. There's two quick ones for me. The first one is just, I guess for William, it's regarding the larger customers have finally this year obviously come under a little bit of share price pressure, partly because of their margins they've been missing and their costs a bit higher than people expected. Have they been turning around to you guys and putting further pressure on your lease rates and what they're paying you? Now I realize that as you mentioned, you're in long-term contracts with them, so obviously we wouldn't expect anything to change in near-term numbers. But for forward contracts two, three, five years out, are you seeing any or hearing any pressure from your large customers on those lease rates? That's the first question. Second question, just a quick housekeeping one for Dan.
I saw the kind of net finance costs increased quite sharply quarter-on-quarter. Were there any one-off costs in third quarter, or is it just related to the increase in net debt that you alluded to in the prepared remarks? Because I see that the interest rates barely changed. Those are my two questions. Thank you.
Okay. Go. Colin, thank you for asking question. I think GDS kind of strategy still stay on the Tier 1 market. In general, I still will say, let's say, in the Tier 1 market demand and the supply still have that huge gap right now. We check how to stay the current price level in short-term. For long-term point of view, I think now our customer more smart.
Michael.
Very smart. They try to deploy the different application in a different type of the product of data center. Different product of the data center, actually, the price is different, the cost is different. It's early to talk about the price difference. Our target, I will repeat that, our target is to maintain our IRR. In the last 12 or 18 months, we made a lot of effort to optimize our design and also drive down our development costs. This latter at GDS has ability, one day the price, we get a pressure from our customer, we still can maintain our IRR.
Yes, Colin, on your question about the effective interest rate. There's a simple reason, which is the convertible bond which we issued, which has a 2% coupon. If you excluded that and we just look at the effective interest rate for the rest of our debt, mainly project term loans and working capital facilities, the effective interest rate would have been 6.7%, which is actually almost exactly the same as what it's been over the first nine months of this year.
Got it. Okay, thanks very much.
Thank you. I'll now turn the call back to company for closing remarks.
