And now I will turn the call over to Tom.

Good morning and welcome to our Q3 call. Financial results for the quarter reflect continued steady growth reporting year-over-year increases in revenue, adjusted EBITDA and FFO per share of 23%, 33% and 35% respectively.

We continue to see solid margin performance with our adjusted EBITDA margin increasing to 50.3% measured over the trailing four quarters ending with and including Q3 2015. This represents an increase of 370 basis points over the comparable period ending with and including Q3 2014.

Regarding sales, our momentum carried into the second half of the year and supported strong production in Q3. Further, we are pleased with our progress across our three primary objectives for 2015, namely, to increase transaction count, further drive network value and bring more leading global public clouds under our platform and on to our CoreSite open cloud exchange.

Regarding transaction count, we again increased the number of leases signed and specifically the number of smaller leases targeted to increase interconnections and drive ROI. In Q3, total transaction count of new and expansion leases reached 149, which is a record for us as a public company.

93% or 138 of the new and expansion leases executed this quarter were for deployments measuring less than 1,000 square feet each. Regarding network value, in Q3 we signed leases to add 37 new network deployments to our platform.

Network wins in the quarter include companies in the subsea, satellite, cable, and mobility sectors in addition to a broad array of fully integrated network service providers. Additionally, new network agreements signed in the quarter represent service providers from around the world including global providers based in North America as well as providers based in China, Hong Kong, India, Japan, Mexico, New Zealand, Sweden, and United Arab emirates.

More broadly over the past four quarters we signed agreements to add 130 network deployments to our platform from all over the globe further cementing our national platforms ability to provide high-performance, low latency solutions to requirements of businesses from a wide array of industries and conducting activities around the world. Beyond our network activities, we're pleased with our progress with major cloud providers as well as the broad set of company's supporting cloud adoption by the enterprise whether in a public, private or hybrid delivery model.

To that, during the quarter we executed 56 leases with cloud system integrator and MSP partners. Included among these is our recently announced initial agreement with Microsoft to provide direct connectivity to Microsoft Azure ExpressRoute within our LA campus representing the only native Azure ExpressRoute deployment in the Los Angeles market.

Azure ExpressRoute is now available to our customers via the CoreSite open cloud exchange and we expect to soon support the service with an API being developed in collaboration with Microsoft. We are excited to launch this partnership with Microsoft and we look forward to expanding the relationship to other markets across our platform.

With regard to new and expansion leases with company's supporting cloud adoption by the enterprise, during the quarter we meaningfully expanded our relationship with a leading global file hosting service provider as well as two Fortune 100 providers of technology services. Among the key capabilities of the cloud, SI and MSP customers with which we executed leases in the quarter, our that FedRamp compliance, security, storage, multivendor service orchestration, software defined networking and other areas of technology support that help make the communities within CoreSite's platform accessible and valuable to enterprises from nearly all walks of life.

With our focus on increasing the networking and cloud density across our platform and attracting performance sensitive deployments, our Q3 interconnection revenue grew more than 24% in Q3 2013 over Q3 2014. Related, we continue to see fiber cross-connect volume growth increasing 16% year-over-year in Q3 with total cross-connect volume growing 12%.

With regard to supply and demand, there been no meaningful changes compared to the update we provided during our second quarter call. Supply and demand dynamics in our industry remain largely in balance and we view the environment favorably as absorption has remained strong in the majority of our markets.

In the performance sensitive segment of the market, supply has remained disciplined with just in time delivery, a standard practice by us and our public peers, supported by steady demand, the performance sensitive market segment continues to see consistent pricing trends. As it relates to the wholesale segment of the market, absorption has remained steady in major markets including Northern Virginia and the Bay Area.

Although supply remains robust in Northern Virginia, existing supply of large blocks of capacity is currently more constrained in the Bay Area resulting in incrementally positive pricing. In New York, New Jersey, we continue to see an uptick in funnel volume, but we have not yet seen a material increase in net absorption.

Regarding our development activity, we have a number of projects underway or recently completed which we believe support continued growth. In Northern Virginia, demand remain steady and we're seeing solid leasing momentum at our Reston campus.

As a component of our leasing in Reston, in Q3 we signed agreements to add three new network providers to the campus bringing the total number of network providers at the location to 32 We believe that the network community established in our Reston campus has helped to support an attractive pipeline of leasing opportunities with social media, digital content and cloud providers. Given the solid pace of leasing at our Reston campus coupled with support from our current funnel, we're under construction on both phase 3 and phase 4 at VA2 representing the remaining components of VA2 targeted for build-out of TKD capacity.

These phases are expected to be delivered in late 2015 and early 2016 respectively. Each phase is approximately 48,000 square feet with 50% of phase 3 pre-leased to our anchor customer at the facility.

In Chicago, we completed construction on 12,000 square feet of TKD capacity in Q3 of which we've preleased 54% with a targeted commencement date in Q4. In Santa Clara, we are under construction on the previously announced powered shell build-to-suit at SV6 and we expect to deliver that building in the first half of 2016.

We also commence construction on our 230,000 square foot SV7 building with an estimated completion of phase 1 in mid 2016. We remain encouraged by the pace of demand in the Bay Area and are optimistic about our opportunity with this investment.

In summary, we are pleased with our team's execution in Q3 and optimistic about our market opportunity closing out 2015 and looking ahead to 2016. We believe the growth potential of our business is attractive and we believe in our ability to continue to execute our business plan.

Our focus remains clear, to provide our customers with differentiated high-performance solutions and industry leading customer service and by so doing continue to deliver strong growth and superior returns for our shareholders. With that, I will turn the call over to Steve.

Thanks, Tom. I'd like to start by reviewing our sales activity during the quarter.

Q3, new and expansion sales totaled $8.8 million in annualized GAAP rent comprised of 64,000 net rentable square feet at an average GAAP rate of $138 per square foot. As it relates to pricing in the quarter, annualized GAAP rent per square foot on new and expansion leases was slightly below the trailing 12-month rate primarily due to lower power density sold in the quarter.

Looking at the performance sensitive segment, the rate per square foot was in line with the trailing 12-month average. As Tom mentioned, we made good progress on our goal to increase leasing volume to smaller customer requirements, executing 138 new and expansion leases of less than 1,000 square feet in Q3, a 25% increase over Q2.

We also saw continued strength in leasing among mid-sized opportunities across our platform signing nine new and expansion leases between 1,000 and 5,000 square feet compared to two mid-sized leases signed in the first quarter and five signed in last quarter. The solid leasing activity particularly the increased volume of smaller deployments contributed to the 53 new logos signed in Q3, a record since CoreSite became a public company.

This continues to be a key focus as we look to further diversify our customer base. In addition to strengthened new and expansion leasing, our renewal activity in Q3 was similarly strong as renewals totaled approximately 72,000 square feet at an annualized GAAP rate of $145 per square foot reflecting mark-to-market growth of 4.2% on a cash basis and 9.7% on a GAAP basis.

On a year-to-date basis, cash rent growth is 4.9%. Churn was 1.4% in the third quarter and is 5.1% year-to-date.

Jeff will update you on our outlook for mark-to-market growth and churn for the full year later in the call. Regarding vertical mix, networking cloud deployments accounted for nearly 60% of annualized GAAP rents signed in new and expansion leases led by significant strength in the cloud vertical.

The network vertical reflected similar strength including key wins with a large global provider deploying new fiber builds in multiple locations across our platform as well as a number of domestic and international carriers deploying new network nodes at LA2, all strengthening the network density and attractiveness of our LA campus. Following a very strong performance in our enterprise vertical in Q2, we continue to see increased penetration into this key market segment.

Specifically, in Q3, leasing in the enterprise vertical accounted for approximately 40% of annualized GAAP rent signed in the quarter. Strength in this segment was led by the digital content and other general enterprises while the number of leases signed by SI and MSP customers increased materially on both a year-over-year and sequential basis.

From a geographic perspective, our strongest markets in terms of annualized GAAP rents signed in new and expansion leases in Q3 were Northern Virginia, DC, Los Angeles and New York. Performance in Northern Virginia/DC was driven by three key factors.

First, we saw a robust leasing activity at VA1 among smaller deployments with 24 new and expansion leases signed of less than 1,000 square feet each, which is two times the average number of leases in this segment signed in the trailing 12-month period. This activity helped increase stabilized occupancy at VA1 to 92.5% at the end of Q3.

Second, we realized continued leasing momentum at VA2 among larger deployments. A sizable component of the leasing at that building during Q3 consisted of an expansion by our original anchor tenant.

The rental rate associated with this final expansion rate was below our average rate of the campus does negatively impacting the total leverage. Occupancy at VA2 is now 87.4% consisting of 100% occupancy in the stabilized space and 50% occupancy in our pre-stabilized space.

Finally, we saw increased strength in the network and cloud communities across our Reston campus. Notably, we have seen steady demand in network-centric applications in the third quarter as well as a steady pipeline of social media, digital media, storage and cloud providers seeking to deploy interconnection hubs at the campus.

At a high level, we are pleased with our progress in the Northern Virginia/DC market during Q3 with over 30 networks now deployed within our Reston campus. Moving to the West Coast, leasing in Los Angeles continue to be well distributed between the two buildings comprising our one Wilshire campus as well as among verticals.

Network and cloud customers accounted for 50% of leasing with digital content representing 30% of leases signed. We also saw very good leasing activity related to our recently completed capacity at LA2.

In Q3, the number of new and expansion transactions were 14% ahead of the trailing 12-month average and annualized GAAP rents signed was more than two times that signed over the same period. Additionally, we recently signed an agreement making LA1 the site of the newly announced faster transpacific submarine cable landing station in LA directly connecting the West Coast of the U.S.

with Japan and the Pacific Rim. The faster transpacific submarine cable deployment represents the seventh subsea cable to offer direct access from our Los Angeles campus to Asian markets increasing our value proposition and providing our customers with enhanced connectivity options.

Further, we continue to bolster our cloud capabilities at our LA campus with the availability of AWS direct connect and now the availability of the only native Microsoft Azure ExpressRoute deployment in the market. In New York, leasing activity picked up from last quarter with 22 new and expansion leases signed, including 10 new logos.

As it relates to distribution of leasing, we signed three leases exceeding 1,000 square feet while the pace of leasing amongst smaller deployments remain solid. Enterprise leasing also picked up in Q3 with nine new and expansion leases signed in this vertical compared to an average of four leases signed in the trailing 12-month period leveraging the network and cloud density we have built across our New York campus.

Related, we have seen significant fiber capacity added from a large cloud provider to support even greater on-ramp capabilities. In summary, we are pleased with our sales momentum in Q3 and our progress on our key priorities, including a solid increase in transaction count and attracting key network and cloud deployments, which enhance our customer communities.

We continue to focus on differentiating the value of our platform and the solutions we provide to our customers supported by best in class customer service. With that, I will turn the call over to Jeff.

Thanks, Steve, and hello, everyone. I'll begin my remarks today by reviewing our Q3 financial results followed by an update on our development CapEx and our balance sheet and liquidity capacity and last, I will discuss our revised outlook and guidance for the remainder of the year.

Turning to our financial performance in the third quarter, data center revenues were $84.6 million, a 6.4% increase on a sequential quarter basis and a 23.5% increase over the prior year quarter. Our Q3 data center revenue consisted of $70.9 million in rental and power revenue from data center space, up 6.4% on a sequential quarter basis and 24.3% year-over-year.

$11.4 million from interconnection revenue, an increase of 7.6% on a sequential quarter basis and 24.3% year-over-year and $2.4 million from tenant reimbursement and other revenues. Office and light industrial revenue was $1.9 million.

Our third quarter FFO was $0.74 per diluted share in unit, an increase of 8.8% on a sequential quarter basis and a 34.5% increase year-over-year. Adjusted EBITDA of $43.7 million increased 7.7% on a sequential quarter basis and 33% over the same quarter last year.

Our adjusted EBITDA margin of 50.5% increased 390 basis points year-over-year and 70 basis points sequentially. Related, on a year-to-date basis, our revenue flow through to adjusted EBITDA and FFO is 67% and 56% respectively adjusted for unusual items in 2014.

Sales and marketing expenses in the third quarter totaled $3.8 million, 10% less than the prior quarter, but in line with the trailing four quarter average. We expect sales and marketing expenses to be in line with the lower end of our guidance of approximately 5% to 5.5% of total operating revenues for the full year.

General and administrative expenses were $8.6 million dollars in Q3 correlating to 10% of total operating revenues. We expect G&A for 2015 to come in at the higher end of our guidance range of 9.5% to 10% of total operating revenue.

Regarding our same store metrics, Q3 same store turn-key data center occupancy increased 760 basis points to 86% from 78.4% in the third quarter of 2014. Additionally, same store MRR per cabinet equivalent increased 3.7% year-over-year and 1.5% sequentially to $1,441.

Lastly, we commenced 66,000 net rentable square feet of new and expansion leases at an annualized GAAP rent of $139 per square foot, which represents $9.3 million of annualized GAAP rent. Turning now to backlog, our projected annualized GAAP rent from signed, but not yet commenced leases is $17.8 million as of September 30, 2015 or $28.2 million on a cash basis.

We expect approximately 30% or $5.4 million of the GAAP backlog to commence in the fourth quarter, another 50% is expected to commence throughout 2016. As a reminder, within the total backlog amount is rent associated with the build-to-suit at SV6 as well as the SV7 pre-lease each forecasted to commence in the latter half of 2016.

Turning to development activity and expansion CapEx, during the third quarter we placed into service two projects at CH1 and LA2 with 11, 700 and 12,500 square feet now reflected in our pre-stabilized approval respectively. We have seen good leasing activity in our pre-stabilized assets, which were 52% lease and 39% occupied as of the end of Q3 compared to 33% leased and 27% occupied at the end of the second quarter.

During the third quarter, we began construction on Phase 4 the last Phase of VA2 with 48,000 square feet under development, which along with 48,000 square feet at Phase 3 is expected to be completed over the next two quarters. As a reminder, when we complete development projects we realize a reduction in our run rate of the capitalization of interest, real estate taxes and insurance resulting in a corresponding increase in operating expense.

As shown on page 21 of the supplemental a percentage of interest capitalized in Q3 was 22% and year to date is 36%. Based on our current development pipeline we would expect the percentage of capitalized interest for the full year to be in line with the year-to-date your today percentage.

Turning to our balance sheet as of September 30, 2015, our net debt to Q3 annualized adjusted EBITDA is 2.0 times and if you include our preferred stock it is 2.7 times. As we mentioned last quarter, based on the current and expected development projects disclosed on page 19 of the supplemental, we would expect our leverage to increase by year end to approximately 3 times, including preferred stock comfortably below our stated target ratio of approximately 4 times.

Finally with regard to our outlook, we are increasing our 2015 FFO guidance to a range of $2.82 to $2.86 per share in OP unit from the previous range of $2.75 to $2.83. The increased guidance reflects our performance through the first nine months of the year and increased visibility into the fourth quarter.

More specifically, we now expect total operating revenue to be $329 million to $333 million compared to the previous range of $325 million to $330 million. Data center revenue is now expected to be $321 million to $325, up from the previous range of $317 million to $322 million.

Adjusted EBITDA is not expected to be $165 million to $169 million up from our previous guidance of $162 million to $167 million implying a full year 2015 adjusted EBITDA margin of 50.5% based on the midpoint of guidance. As it relates to churn, we now expect full year 2015 turn to be in the range of 8% to 9%.

Year-to-date churn at the end of Q3 was 5.1% and as we have previously communicated, we expect an incremental 150 basis points of churn at the end of Q4 related to the lease amendment debt SV3. In addition, we expect some churn related to a particular customer deployment in Chicago in either Q4 2015 or Q1 2016.

Cash rent mark to market growth is now expected to be 4% to 5% for 2015, up from our previous guidance of 3% to 5%. This reflects our year to date performance of 4.9% and improve visibility into Q4.

While we will provide formal 2016 guidance in connection with our fourth quarter earnings call in February, I want to highlight a few items as you begin to think about your models and the Outlook for growth next year. First, as it relates to our adjusted EBITDA and FFO margins as we go forward, we would expect to see a moderation in the rate of expansion, primarily due to product mix.

As we have discussed previously, the volume of larger leases signed over the trailing 12 month period impacts our earnings margin given the greater proportion of metered power associated with these deployments. While we mentioned on previous calls this year that we expected to see limited margin expansion in 2015 with greater opportunity to expand margins in 2016, the build-out and power draw are still ramping in from several of our newer wholesale deployments.

As such, we have seen attractive margin expansion in 2015, but now expect more limited opportunity from margin expansion in 2016. We will provide more detail around us on our Q4 call in February.

Next, our available capacity under the credit facility plus cash at the end of Q3 is $243 million. Based on the development projects as reflected on page 19 of the supplemental, we anticipate spending $116 million of expansion capital through June 30, 2016 leaving us with current uncommitted liquidity of approximately $80 million.

Based on this development pace plus the potential opportunity to fund additional investments, we're currently assessing the capital markets to decide the timing, amount, and the type of debt instrument to increase our liquidity to support future growth. Last, as it relates to churn for 2016, we would remind you that we expect an incremental 90 basis points of churn in Q2 2016, due to the SV3 lease amendment and as disclosed in our supplemental and 10-Q to be filed tomorrow.

A more detailed summary of 2015 guidance items can be found on page 23 of the third quarter earnings supplemental. I would remind you that our guidance is based on our current view of supply and demand dynamics in our markets, as well as the health of the broader economy.

We do not factor in changes in our portfolio resulting from acquisitions, dispositions or capital markets activity other than what we have discussed today. Now we’d like to open the call to questions.

Operator?

Thank you good morning. First question is, I guess also looks at into the future a little bit leaving off where Jeff, you wrapped up your prepared remarks.

I guess I’m curious a little bit about capacity and as you’ve been very successful over the last four quarters or so leasing up the portfolio I’m curious about while you’re in the process of assessing your capital needs, the process in assessing the need for additional capacity across the portfolio and how we should think about that either geographically or from a product perspective?

Thanks Jordan. I think at a high level, just pays to think of what we’ve been communicating in terms of our priorities for capital.

So, really if you look at the markets we're in right now and where we’ve had the most absorption, then do that math and look at how much is remaining to be available to either be developed or remain to be sold right now that’s already turnkey that points you to where we’re focused. I think we’ve had accelerated leasing in Virginia VA2.

The SV7 building is the last building available to be built on our current landholdings in Santa Clara. It’s a big building, but it is the last one.

We're running short in Chicago. So, same list of suspects and we’re just evaluating what are the opportunities for investment and what are our returns and we're just working through all that with our board, but I think the easiest way to think of where we’re going to spend our time is in line with those capital deployment priorities that we’ve been articulating.

And we just don’t have anything specific to say right now other than, we're 2.9 times levered. We have capacity to keep growing.

We have some markets where we’ve had success that we’re getting lean and we're just trying to be economically rational about what to do about that picture.

Okay. And geographically, any thoughts or need to expand beyond the current footprint or like the way you are situated today?

Well, no change to Pat's comments. All things being equal, more markets are better, but I don't think that’s a hugely meaningful driver for us.

And in particular, if you look at this Q, which I think is not that different from past Qs we are attracting a global customer base here in the States. I think we’re effective with platform requirements and we just don't feel meaningfully disadvantaged because of the market coverage.

We feel like we’re in the best places in the U.S. with a vast majority of them with the most data center demand in the country that we’re addressing through our portfolio.

So, we are pleased with our ability to keep growing in the markets we are currently in and on a risk-adjusted basis that’s highly attractive. That’s not to say that something else might be attractive at some point in time, but the table that is set before us is good and plentiful.

Okay. And then on the mark-to-market increase, I’m curious if that’s coming from market rent growth or if it’s a combination of market rent growth and the focus on the smaller transaction, what exactly is driving that?

Yeah, Jordan this is Steve. It’s really a combination of both of those things.

We're seeing obviously strength in the marketplace that allows us to hold rent and that’s encouraging, but we're also seeing better traction in those smaller deployments which we built in some other renewals that help us in that regard, but overall renewals seem to be solid so we’re pleased with both sides of the equation.

And keep in mind Jordan that the mark-to-market stat is leases that were in the portfolio at the end of the Q and that renewed so that stat does not pick up selling to new customers.

Right, right okay. I get that, I get that.

Lastly, just more housekeeping oriented, there was a transaction costs in litigation, it showed up as two different numbers in two different places and I was wondering what might have driven the Delta litigation seems to be added to the second spot in the supplemental and what the nature of those expenditures might have been.

Yeah, Jordan, you're probably referencing roughly $650,000 in the quarter and those costs are largely attributable to some certain legal issues that we’re working through a couple of situations and that’s substantially what those costs relate to.

I think those accruals are for two different items and when you look at the amounts, I don't think they are game changers for the company but we felt it appropriate to take some reserves against two different items. And they are unrelated.

Should they be recurring or is this hard to predict?

I think it’s difficult to predict. In general, we don’t have much litigation at the same time you have some the bigger a company gets you’ve got slip and falls, you’ve got all kinds of stuff out there and it is hard to predict.

I think it’s rare that a company of any size never has anything and I think it’s equally rare that we’ve had anything material.

Okay. Thank you.

Thanks, Jordon.

Thank you for taking the questions. First, I just want to follow up on the development of your cloud communities, obviously you guys have made a lot of progress in getting Microsoft as your on ramp in LA.

It was an exciting announcement. Can you give us a little bit of perspective on the development of the other side of putting together these cloud ecosystems that is, where are we as a company or as an industry in terms of seeing enterprises come into plug-in to the multi cloud environment or into the cloud ecosystems that you’re developing and then I’d like to follow up with maybe a couple of detail-related questions, thanks.

Sure, Jonathan. This is Steve.

I’ll give you my comments and then I'll let Tom wrap up, but in general I would say that it’s of greater interest for the enterprises to want to have that connectivity flexibility within our data center. So, we work to provide that flexibility across our open cloud exchange and with the reconnect and various other providers, so that’s driving a lot of activity on our end to make sure that we accommodate that from an enterprise perspective.

But we’re also seeing greater interest from the other side from the cloud providers wanting to connect back into those enterprises so between the two, we’re at a very nice place in the marketplace where we’re in between those two and being able to provide those connections. So, we look at it to be a continued focus for us as we go forward in part of the value proposition that we built into our data centers.

So, I think it will continue to materialize and something will be continued focus for us as we go forward.

But if you had but - go ahead Tom, I’m sorry.

I think it’s very early innings still, we’re just measured by cross connection to what extent our enterprise is connecting into the clouds. We’ve had one of the large public clouds, their providers who’s been with us longer than others and I’d say the first year they didn't, we didn't see a lot of enterprise take up around that offering.

I see over the last year, we’ve seen it connections accelerate pretty meaningfully. That said it’s still relatively small compared to the size of our company or all cross connects here, so I would say that we are starting to see it in the more mature deployments, but I still think it’s very early.

Great, thanks Tom. Ironically I was going to ask you what inning we were in, but you seemed to have nailed that one.

A couple of detailed questions here, there was a $8.8 million of capitalized commissions in the quarter. I think that was somewhat of an anomaly from what we were expecting.

Is there any incremental color around that?

Yeah, Jonathan, just to give you a little bit of color around the $8 million, I would say roughly 60% of that amount relates to external commissions, the rest of it are internal and of that external piece, a major component of that related to a single multi-market new logo that we signed during the quarter and anticipate commencing in Q4.

Okay.

I think it’s important to understand the cash around that as well.

Yeah, I guess just to give you a little bit more color, that particular, for the one particular transaction is a transaction whereby the lease or the commission amounts will be paid out over the life of the particular term of that deployment as we collect cash from our particular customer. And so while it will be paid over a period of the customers’ term, the supplemental reflects the entire amount that we anticipate paying out over that period of term just so you have an understanding of how that works.

We provided some additional disclosure inside the supplemental in our definition just to make sure that gets cleared up for people.

Jonathan, just the simple I guess the clearest thing we can say is the meaningful transaction to which Jeff referred is with an agent rather than a real estate broker, it’s more of the telecom based agent on a longer-term multi-market deal and our work with our auditors and internally with our team pointed toward capitalizing all of those payments even though we paid that agent as we received the money over a longer term, capitalizing that and then accruing it as a liability since we haven't paid the cash. So, if you are trying to, as I think most people are trying to look at AFFO on a cash basis, a big chunk of the AFFO is frankly a noncash item in this quarter.

Yeah, all right, thanks for that extra color. I’ll just ask one more here and then I’ll circle back in the line, but look it was a very solid quarter again for you guys and you’re able to bring up the guidance.

It’s interesting to me that where we are in the year and the fact that there's usually a fairly decent lag time between the time deals are signed and they start to generate revenue to see you be able to take up numbers and so I’m wondering as we look at your guidance increase this late in the year if this had to do with faster leasing or faster commencements or delayed churn like what are the factors that roll together to allow you to move the numbers here? Thanks.

It’s leasing. Our churn has been in line, our mark-to-market has been in line, so it’s really leasing.

There you have it.

All right. Thanks guys, really appreciate you taking the questions.

Yeah.

Thanks, Jonathan.

Thanks. So I was interested in any noticeable change in the demand or activity in your business as a result of the large M&A deal that recently closed and then, related to the commissions question, overall if you could talk about how much of your leasing is a result of direct sales to customers versus indirect channels?

Thanks.

What’s the M&A deal you’re just talking about? I have no idea.

I’m sorry, I’m kidding there. Steve do you want to talk about what you’ve seen?

Yeah, I would say from the M&A deal that you’re discussing, I haven't seen a whole lot of difference in the marketplace relative to how we’re competing and how they're showing up as of yet. That may change over time but as it sits today, nothing material.

I just think it’s too early.

And then Jonathan on the second one, I think in terms of I guess what the number of deals that would be coming through I think you said the channel and/or broker, I think on average it’s going to vary based on and it’s good to be driven by the size of those leases, but on average it’s anywhere between 10% to 20% is what we would typically see. That’s typically what we’ve seen over the last several years in terms of number of leases.

Number of leases, okay, got it. And then I'm interested in the growth, not the absolute volumes of interconnect revenues but just the growth you’re seen in interconnect and how much of that would you characterize as coming from customer to carrier versus a customer to customer within your data centers?

Any sort of change in the mixed shift and what should be the predominant driver?

I think you are seeing some increase in the share that is non- carrier related or put differently enterprise to enterprise, enterprise to cloud, but the majority still remains involving a carrier.

And then related to that, there is open cloud exchange and then there is design wins that can ExpressRoute and Direct Connect and if we isolate cloud related activities into those two buckets, which would be the more meaningful incremental driver that you’re seeing right now?

Between what John?

Open cloud exchange versus the cloud specific on-ramps that you’ve got like an ExpressRoute and Direct Connect and then perhaps a few others.

We are kind of the same. ExpressRoute with us is number one, [indiscernible] the number two and it’s currently only on the exchange and that’s the request of the service provider.

So I'm not sure how to answer it. There is a fair amount of – sorry.

Go-ahead. I thought that those might be separate particularly in the case of say Direct Connect where some of that might come directly from the customer onto that cloud rather than through your CS platform.

And with Direct Connect, that’s accurate. The majority of connections into Direct Connect are via Cross Connect.

And with [indiscernible] to different animal right now because of how they have come to market in our portfolio.

Got it. Thanks very much.

Hey, good morning, Tom. I had a question for you I guess around the network wins.

You talked about 37 I think network wins in the quarter, 130 in the trailing 12 months if I got the numbers right. I'm just kind of curious that the market is experiencing the same type of growth if you think within your markets you’re just winning a tremendous amount of share in that business.

I guess I just love a little bit of more color around the network side of the business if you could.

Yeah, sure. This is Steve.

I'm going to start off here. I think we are attracting a fair share or maybe more than our fair share of the activity in that marketplace driven by increased strength in the enterprise space and just increasing the value in our hubs in LA and DC and so forth.

But I think just the overall industry is seeing significant growth as you've seen in recent reports on the news that the value of Cross Connects and the interconnection strengthen the marketplace. So that’s just driving more and more connectivity to the data centers in general but I think we’re seeing a pretty good share of that come to our data centers which is great.

Great, thanks. Second question maybe around the Cross Connect side of the business, can you give a lot of details about fiber and total connect volume but I guess I was curious more on the market pricing that you are seeing out there with regard to Cross Connects?

I know you’re continuing to inch up and mark-to-market in that business, but I’d like to know a little bit more about market pricing if you could comment on that? And then a second to that was, you talked about a large cloud customer impacting the Cross Connect volumes, was that a meaningful change, will that continue to be or is that something that we should see ebb in the next quarter maybe I didn't get that clearly.

First on pricing, Dave, I think we haven't seen material changes in the market and as such we have been as you've said inching and marking our portfolio closer and closer to market but I haven't seen the market change a lot. So that's - that one.

And regarding the cloud, Cross Connect to the cloud, I think that was in the context of may be responding to Jonathan around, to what extent is the enterprise really adopting the cloud? So we’ve had - one of our early cloud partners, we have seen significant growth in Cross Connects for that partner from enterprise over the last year.

That total volume is still not tremendously, it is still not material I think related to our total Cross Connect base. So if you think about the Cross Connect business I wouldn’t describe anything material to that, it’s a higher growth rate but often the smaller base.

Okay, that’s helpful. Last question maybe for Jeff.

Jeff, you talked about churn, it looks like the churn for the fourth quarter is 3.5% to 4% plus or minus. You mentioned the extra customer in Chicago.

If that customer I guess were to leave in the fourth quarter would that take churn above that number or is that embedded in the number and it could come in lower if it slips to the first quarter?

Yes, Dave. The guidance we’ve given for Q4 includes the possible churn of that particular customer.

So again while we are not certain of the timing or of the amount, we wanted to make sure people were at least aware of it at this point in time, especially if we have visibility into it. So we’ve included that in our Q4 churn.

Okay, great. Thanks guys.

You bet.

Great, thanks. Two if I may.

Just wanted to follow-up on the initial question regarding pipeline, so when you are looking for space, are you still seeing there's a lot of space available in the markets where you are going to need it that you’ll be comfortable taking on and be able to turn into a type of facility that you’ll be happy with I guess starting as far as just going to the land itself. And if you look at over the next 12 months, do you see any markets where you guys could be capacity constrained relative to demand that you're seeing today to the point where that could actually start to impact your top line growth at least for a brief period of time until you get that space brought on?

And then my second line of questioning is, recently there has been some talk whether it came from Cisco or Intel around some weakness in data center demand and I very much appreciate the term data center is a very broad term and very much appreciate that there has been a debate for many years now about does cloud ultimately eat Colo. But I would love to get your take on what you see happening and is there any risk you see longer-term from some of your for example digital media customers shifting from a Colo-type model to perhaps more of a cloud model and how that might impact you?

Thank you.

Sure. I guess related to the capacity and room to run inside the portfolio, first we focus on earnings and for the extent capacity is a component of that, it is certainly is a component but we are really focused on earnings growth and I would say over the last couple of years we have had spots where we have been very tight in some markets and more capacity in others.

I don’t expect that to change. I think there may be some markets where we get reasonably thin but we really do look at our planning and we try to look pretty hard out five years, what is the growth of earnings of the company and in the near term, we believe there remains a good opportunity for the organization, a good market opportunity and a good physical platform and a good balance sheet inside the company to maintain healthy growth rates.

That is our belief. We are certainly not trying to – we are very aware of not running out of space everywhere and not being able to grow.

We are measured and we plan pretty carefully and there are soft spots from time to time in some markets and over the years we have been able to navigate that pretty well.

And weakness in demand overall, rumors out there.

Let our sales speak for themselves. I did see the note from Intel and the weakness in data center demand I guess they’ve been putting their gear into data centers as opposed to demand for their data centers.

I know they have some type of third-party products, but I guess we can only see what we see. Steve, any comments on that?

Yeah, I would just say that we haven’t seen that shelf in our pipeline as of yet, so we keep a close eye on it and we monitor and try to adjust to it but all those factors are important. But at this point we haven't seen them show up in our pipeline.

Thanks.

Thanks, Colby.

Thank you. Good afternoon.

If I could go back to the cloud exchange concept and just think about our cloud providers over provisioned today given what they anticipate in terms of future enterprise demand or would you think it is more of an add-on affect when the enterprise starts to meaningfully adopt the product or the solution, and how meaningful could that add-on affect be from the service providers standpoint?

Sure. I’ll start off with give you my perspective.

This is Steve. I think it varies pretty broadly across the various cloud providers out there.

We’ve seen over the past several years cloud providers come and go, some that have over provisioned and not seen the demand and had their gear be antiquated and not competitive and we’ve seen others be much more measured and seen better adoption. So the big players out there are much better at it and they will come in and build out and then plan on scaling from there and that is part of our value proposition is being able to accommodate that scale.

It has been a mix but I think many of the cloud providers have gotten much smarter over the past couple of years as to what they deploy and how they measure that growth and as adoption comes along with it. so it seem to be maturing and with that maturity we’ve seen more consistency.

Okay, that’s helpful. Thank you.

And then I'm not sure I’ve heard you guys talk much about escalators built into your contracts and I’m just kind of trying to get a sense of, as I look at that same-store MRR per cab growth of 4% to 5% and that’s been pretty consistent, how much of that is a base rent or cash rent escalator versus just overall growth in the cross connects?

Matt, is going to really be a combination of the two I think. When you look at the overall growth in the MRR per cab-e, historically we’ve talked a little bit about and we haven’t seen a meaningful change that typically about 75% of that growth from the MMR per cab-e comes from increases in power and cross connects.

The other 25% is coming from the rent component. And so while there are escalations, cash escalations inside most of our contracts or I should say majority of our contracts that helps drive that to some extent but the lion’s share of that growth continues to come from both increases in power and cross connects.

Okay, thanks. And can you quantify what the average escalator is written in?

I think overall I’d say ballpark-ish is 3% of a relatively on an annual basis a relatively good data point.

Okay, thanks guys.

Thanks, Matt.

Great. Thank you.

I am curious about the [indiscernible] connection, a lot of people have asked question kind of about what it means in terms of demand and all that stuff. What I'm more curious about is how do you guys get these deals to start with?

What is the negotiation process? Is it something that you have to pay for?

I'm sure it is something that you and all your competitors want as well so how does it end up in a CoreSite facility and what are the contracts like? How long are you locked up in terms of having the only connection in the market or could that change tomorrow?

I guess first, bringing them in actually - Steve, do you want to talk about how the process?

Go ahead.

In bringing them in, I don’t recall that we’ve ever paid a cloud provider to launch inside our platform and it really just comes from how do we get them but we have long-standing relationships with these companies. We have people who work together with their people for years.

And I just think those discussions start fairly early in the product planning cycle and it is a – that’s the process, that is it. We have not signed anything, CoreSite has not signed anything that locks any cloud provider out of announcing or working with other parties in the marketplace so that dynamic does not apply to CoreSite.

The other thing I would add is, we do have very good relationships with many of the largest cloud providers and we do work with them on a continual basis. As far as how we start and ultimately formalize those relationships, it is a mutual interest so they want to have access to our customers, we want to have access to their cloud and as I mentioned earlier that makes pretty easy conversation, how we get there varies from cloud provider to provider but we are all interested in the same thing.

Gotcha, okay. And then lot of people have talked about capacity and the runway in new markets and all of that stuff, I'm just kind of curious I know you have nothing new to announce in terms of plans for new markets but just internally how much time do you guys spend amongst yourselves or meetings with the board talking about potential markets you would want to be in whether it is domestic or international, how much of your strategic planning time do you spend thinking about that?

How we deploy capital and how we think about our investment returns is certainly a key topic for the Board and for the Executive Team as we think about the strategy. There are times when that strategy is pretty well set for the next year, year and a half and as such we don't talk about it quite as much.

There are times when there is more to talk about but we maintain a good discipline around thinking about how to invest, we are a capital intensive business and our Board is very rigorous and disciplined about staying up to speed on our strategies and helping us think through those things. So I can’t quantify - it ebbs and flows with the needs of the company but it never goes away because we never stop thinking about it.

Gotcha, okay. That makes sense.

And then just one other question for Jeff, it sounds like to fund development spending with the pipeline you have right now I think you had about 160 million-ish left and it sounds like there is going to be some new debt issued. Can you give us any indication of the timing around that, what kind of routes you would use on that and then I'm also just curious with your leverage levels as low as they are, you guys have a fairly diversified portfolio, you’re now a larger company than you were at the IPO, what kind of conversations you had with the ratings agencies about moving towards investment grade rating?

Yes, let me see if I can give you some color as best as I can Jon. I guess somewhat as I said in my prepared remarks as we look out over the next call at nine months through June 30 of next year is kind of where we're looking from a timing perspective between now and then and ultimately it’s going to depend on the things that really matter to us which is maintaining flexibility so that we can continue to trend towards that investment grade rating.

And maintaining an unsecured instrument is obviously key from our perspective. As you’ve seen we like to maintain a balance between fixed versus variable price debt and then obviously maintain an appropriate debt maturity stack in whatever it is we do.

In terms of conversations with rating agencies, we meet with the rating agencies at least once a year with each of them, the main ones to make sure that we stay in front of them. We learn from how they are looking at things, how they look at the industry and importantly so they also understand what CoreSite is doing, has done and ultimately probably more importantly where we are headed.

And so we have those conversations in terms of actually timing around a rating. That will really depend on when it is needed or sometime before it is needed but nothing at this point in time is concrete.

Okay. Thanks for the color.

You bet. I just want to respond to the prior question or about the growth rates and escalators built into our contracts et cetera.

I want to make sure we are clear. You could hear what we shared as – if you have 3% escalators on rent and you are getting four on your mark-to-market and how can you be getting any more than a point on power and interconnection, and I think that would be - if we’ve led towards that I think we’ve misled you guys.

It has been an incorrect analysis. What is key inside the MMR per cab-e is we’ve been adding a lot of wholesale into the mix over the last couple of years, so the escalators are in the smaller agreements and the wholesale is typically at a lower MMR per cab-e than the rest of our business.

So I think in general when you see wholesale, a flag of wholesale coming in because of a round of new development but you are still seeing reasonable strength in the MMR per cab-e. Generally speaking I think what you have is very solid strength in MMR per cab-e inside the transaction engine in the performance sensitive side of our business being diluted by wholesale.

And so I just want to make sure we're super clear about the component of MMR per cab-e. It is a moving base with more wholesale having come in over the last couple of years and that has muted what you might have otherwise seen from the rest of the portfolio, escalators, cross connects, break or power et cetera.

I just wanted to touch on that to make sure we are clear.

So with that, I think we’ll wrap it up and just want to say thank you to everybody for taking time with us on the call today and for following the company and working hard to understand what we're doing and where we're trying to go. We will keep working hard.

We are very grateful for our people here at CoreSite to drive our success and for the customers to keep putting their faith in us. Thanks again, we will talk to you soon.
