Good morning and welcome to Acuity Brands fiscal 2016 third-quarter financial conference call.
After today's presentation there will be a formal question-and-answer session.
(Operator Instructions).
Today's conference is being recorded.
If you have any objections, you may disconnect at this time.
Now I would like to introduce Mr. Dan Smith, Senior Vice President, Treasurer and Secretary.
Sir, you may begin.
Dan Smith - SVP, Treaurer and Secretary
Good morning.
With me today to discuss our third-quarter results are Vern Nagel, our Chairman, President and Chief Executive Officer, and Ricky Reece, our Executive Vice President and Chief Financial Officer.
We are webcasting today's conference call at acuitybrands.com.
I would like to remind everyone that during this call we may make projections or forward-looking statements regarding future events or future financial performance of the Company.
Such statements involve risk and uncertainties such that actual results may differ materially.
Please refer to our most recent 10-K and 10-Q SEC filings in today's press release which identify important factors that could cause actual results to differ materially from those contained in our projections or forward-looking statements.
Now let me turn this call over to Vern Nagel.
Vern Nagel - Chairman, President and CEO
Thank you, Dan.
Good morning everyone.
Ricky and I would like to make a few comments and then we will be happy to answer your questions.
First off, our results for the third quarter of 2016 were outstanding.
Our net sales grew 25% while our adjusted diluted earnings per share grew 40%.
We achieved record quarterly results for a number of key financial metrics including net sales and gross profit margin and on an adjusted basis, operating profit and diluted earnings per share.
In fact, this was our 13th quarter in a row where we achieved double-digit volume growth, a remarkable achievement.
We believe these results are yet again strong evidence our strategies to provide customers with differentiated value-added solutions and to diversify the end markets we serve are succeeding allowing us to extend our leadership position.
These strategies include accretive acquisitions, the continued aggressive introduction of innovative energy efficient lighting and building automation solutions, expansion in key channels and geographies, improvements in customer service and company-wide productivity gains.
Our results for the third quarter set records for Acuity even as we continued to invest in our strong sales growth in areas with significant growth potential including the expansion of our solid-state luminaire and lighting controls portfolio as well as our building automation and Internet of Things solution.
I know many of you have already seen our results and Ricky will provide more detail later in the call but I would like to make a few comments on the key highlights for the quarter.
Net sales for the third quarter were $852 million, an increase of 25% compared with the year ago period and the highest quarterly sales in our history.
Reported operating profit for the third quarter of 2016 was $121 million compared with reported operating profit of $99.2 million in the year-ago period.
There were adjustments in both quarters for certain special charges which Ricky will describe later in the call.
Also our reported operating profit included items such as share-based compensation expense, costs associated with acquisitions and certain purchase accounting adjustments including profit and inventory and amortization expense for acquired intangibles.
In order to make our results comparable between periods, we find it helpful to add back these items to our reported results.
In doing so one can see adjusted operating profit for the third quarter of 2016 was a quarterly record of $146.1 million compared with an adjusted operating profit of $108.1 million in the year-ago period, an increase of 35%.
Adjusted operating profit margin was 17.2%, up 140 basis points from the adjusted margin in the year-ago period.
Adjusted diluted earnings per share was a quarterly record of $2.06 compared with adjusted diluted EPS of $1.47 in the year-ago period, up 40%.
This is compelling performance.
We closed the quarter with $337 million of cash on hand after investing $614 million for acquisitions this year leaving us with plenty of financial firepower to execute our growth strategies.
Further, we generated a record $244 million from net cash provided by operations in the first three quarters of 2016, up $86 million or 54% from the year-ago period.
Our record results for the quarter were significant improvements over the year-ago period.
We believe you will find our results for the quarter even more impressive upon further analysis.
Net sales for the third quarter grew 25% compared with the year-ago period.
We estimate our sales volume grew by an impressive 16%.
The additions of Distech and Juno increased net sales another 12 points while changes in price mix and foreign currency reduced net sales by approximately 2 points and 1 point respectively.
While it is not possible to precisely determine the separate impact of price and mix changes on net sales, we believe the difference was primarily due to lower pricing on like kind LED luminaires between periods reflecting the decline of certain component costs and to a lesser degree changes in the mix of products sold.
The increase in net sales was broad-based along most product lines and sales channels.
Sales of LED products at Acuity now account for approximately 60% of our total net sales which as you know includes the sale of non-fixture related products and solutions as well.
Lastly, we believe our channel and product diversification as well as our strategies to better serve customers with new, more innovative and holistic lighting and building automation solutions and the strength of our many sales forces have allowed us to get yet again achieve meaningful sales growth this quarter.
Before turn the call over to Ricky, I would like to comment on our profitability and strategic accomplishments for the quarter.
As we noted earlier, our adjusted third-quarter operating profit was $146.1 million, the most in our history and adjusted operating profit margin for the quarter was a quarterly record of 17.2%, up 140 basis points from the adjusted margin in the year-ago period.
Further, our adjusted gross profit margin for the quarter was a record 44.5%, up 130 basis points compared with the year-ago period.
The expansion of our adjusted gross profit margin was primarily due to the benefits of higher net sales volume, productivity improvements throughout the supply chain, and lower input costs partially offset by the addition of Juno which in its recent past has had a lower gross profit margin than Acuity.
Next, total selling, distribution and administrative expenses excluding the adjustment items noted earlier for each quarter were up $45.2 million or 24%.
Adjusted SDA expenses as a percentage of net sales were 27.3% in the current quarter, a decrease of 10 basis points from the year-ago period.
The increase in adjusted SDA expense was primarily due to higher freight and commission costs to support the increase in net sales, the impact of acquisitions and to a lesser degree higher compensation costs.
The increase in compensation costs was primarily due to additional headcount to support and drive our tiered solution strategy.
This next point is very important.
Another way to view just how robust our third-quarter results were is to examine our variable contribution margin excluding the impact of acquisition.
On a comparable basis, our variable contribution margin as a percentage of net sales was approximately 30%, well above our current target of mid to upper 20s.
All in all we had another great quarter.
On the strategic front, we continue to make great strides setting the stage for what we believe will be strong growth and profitability in 2016 and beyond.
Internally we continue to accelerate the deployment of our lean business processes driving greater productivity and enhanced customer service.
We continued our rapid pace of introducing new products and solutions, expanding our industry-leading portfolio of innovative energy efficient luminaires and lighting controls as well as our building automation platform.
With the addition of Juno, we now offer customers more than 1.8 million lighting SKUs to choose from, more than three times as many as we had in 2008.
To our knowledge no other lighting company provides customers with more choices and solutions than Acuity Brands.
Much of this growth in our portfolio has been driven by the expansion of our digital lighting solutions portfolio including controls and now building automation system and IoT application.
Innovation continues to be at the forefront of our strategy.
For example, our innovative LED solutions earned multiple awards from the industry's most prestigious programs during Light Fair International including the 2016 LFI Innovation Award and the Next Generation Luminaire Solid-State Lighting Design Indoor Competition.
Additionally we continue to invest in and expand our capabilities to drive our integrated tiered solution strategy which consists of four tiers.
The purpose of this strategy is to lever our incredibly diverse and growing portfolio by offering customers solutions that best meet their needs whether it be a single device which we categorize as Tier 1 or a complete holistic integrated lighting and building automation solutions which we refer to as Tier 3 for their indoor and outdoor needs and everything in between.
We deliver this comprehensive portfolio all with the promise and security from Acuity that these solutions are smart and simple both to install into use.
These are compelling and powerful value propositions for our customers and a competitive advantage for Acuity.
The additions of Distech, Geometri and Juno have meaningfully enhanced our industry-leading capabilities and solutions portfolio.
While sales [slated] for our tiered solutions is still in precise and expanding off a small base, we believe sales of our Tier 3 category encompassing our holistic integrated solutions were up approximately 40% through the first three quarters of this year over the year-ago period and now represent almost 10% of our total sales.
Furthermore, our Tier 3 solutions can be enabled to collect data and to support connectivity through the Internet of Things affording Acuity additional revenue streams which we identify as Tier 4 solutions.
To fully execute our holistic tiered solution strategy, we have continued to hone our organization structure to be more customer centric, leveraging our industry-leading access to market and to better allocate resources among each of our tiers creating the best solutions for our customers' applications.
We have added enormous capabilities over the last year including our recent acquisitions as well as increased salaried headcount to support the growth as part of this overall tiered solution strategy.
Additionally, now that LED is widely accepted, the attention of customers is focused on how they can best control and utilize this light source to optimize their visual environment while realizing additional benefits including energy savings and the opportunity to have a smart connected platform to enable the Internet of Things.
Because Acuity truly understands how best to fully utilize the unique capabilities of digital lighting through our smart and simple solutions for virtually any application and with the addition of Distech Controls, we believe we are uniquely positioned to grow much faster than the markets we serve.
At Acuity, we are not just talking Internet of Things, we are doing it.
Over the last 12 months, we have converted over 12 million square feet of space for customers including Target and two other global leading retailers with smart lighting solutions.
As part of their smart lighting solution, we currently have almost 200,000 maintenance free beacon-enabled LED lighting fixtures that are performing superbly collecting data and enabling applications that provide users with superior lighting and energy performance as well as useful, actionable information.
We believe this level of capability and deployment is unmatched in our industry.
Importantly, we expect this installed base to quadruple by the end of 2016.
Further, Target selected Acuity as its exclusive smart lighting solutions provider.
The integration of Distech, which operates in its historical markets as more of a standalone company is moving along very well.
We expect the combination of Acuity with its broad industry-leading solid-state lighting portfolio, innovative control technologies and integrated digital solutions and Distech to contribute to our tiered solution strategy by offering holistic unified solutions that deliver true end-to-end optimization of all aspects of the building.
These solutions are designed to enhance the occupant experience, improve the quality of the visual environment and provide seamless operational energy efficiency and cost reduction as well as increased digital functionality due to a unique capability to collect vast amounts of data that can better enable the Internet of Things for building owners.
In fact, we just introduced [nLight Eclipse], a powerful cost-effective capability that enhances our industry-leading lighting controls by making them far simpler to deploy and more impactful at delivering total smart building solution that unifies lighting, HVAC, power metering and security.
This solution set streamlines building programming, facilitates our smart multi-zone daylight harvesting and color tuning capabilities and enhances IoT access.
We believe the capabilities and ease of installation of this Tier 3 solution set is unmatched in the industry today.
Through the deployment of solutions like these as part of our tiered solution strategy, Acuity Brands is driving the evolution to smart buildings and smart cities.
We expect these recent strategic acquisitions coupled with our aggressive internal investments will allow us to continue to diversify and strengthen our foundation as we further serve as a robust platform for our future growth that is less reliant on the new nonresidential construction cycle.
We have been able to produce these results because of the dedication and resolve of our now 10,000 associates who are maniacally focused on serving, solving and supporting the needs of our customers.
I will talk more about our future growth strategies and our expectations for the construction market later in the call.
I would like to now turn the call over to Ricky before I make a few comments regarding our focus for the balance of 2016.
Ricky?
Ricky Reece - EVP and CFO
Thank you, Vern, and good morning, everybody.
As Vern noted, we had a strong third-quarter performance on virtually all metrics including sales and earnings growth, profitability and cash flow.
I will provide a bit more color on our record third-quarter results and our financial position.
As Vern mentioned earlier, we had some adjustments to the GAAP results in the third quarter of fiscal 2016 and 2015 which we find useful to add back in order for the quarterly results to be comparable.
In the third quarter of fiscal year 2016, we added back $1 million or $0.02 per diluted share for various acquisition related items; $7.5 million or $0.11 per diluted share for the amortization of acquired intangible assets; $6.9 million or $0.10 per diluted share for share-based compensation expense; and $9.7 million or $0.14 per diluted share for special charges related to streamlining activities including integration of recent acquisitions and consolidation of certain production activities.
We adjusted prior-year results for amortizations of acquired intangible assets of $2.8 million or $0.04 per diluted share; share-based compensation expense of $4.4 million or $0.06 per diluted share; acquisition related items of $1.3 million or $0.03 per diluted share; and special charge of $0.4 million or $0.01 per diluted share.
In addition, we adjusted prior-year results for the gain on financial instruments used to hedge the Distech Canadian dollar purchase price of $10.5 million or $0.15 per diluted share.
These adjustments to our GAAP earnings resulted in an adjusted diluted EPS of $2.06 for the third quarter of fiscal 2016 which is a 40% increase compared with the $1.47 adjusted diluted EPS in the year-ago period.
We believe these non-GAAP measures provide greater comparability and enhanced visibility into our results of operations.
We think you will find this transparency very helpful in your analysis of our performance.
In addition, many of our peer companies make these same adjustments so it will help you as you compare our performance to other public companies in our industry.
In our earnings release and Form 10-Q, we provide a detailed reconciliation of non-GAAP measures.
During the third quarter of fiscal 2016, the Company recorded a pretax special charge of $9.7 million for actions initiated to streamline the organization including the integration of recent acquisitions.
These streamlining activities include the consolidations of selected production activities and realignment of certain responsibilities primarily within various selling, distribution and administrative departments.
We expect to achieve net annual savings of at least twice the amount of the special charge commencing at the end of the first quarter of fiscal year 2017.
We anticipate incurring additional costs associated with these and potential future integration and streamlining activities in the fourth quarter of fiscal year 2016.
The effective tax rate for the third quarter was 34.3% compared with 36% in the third quarter of last year.
We expect the effective tax rate for the fourth quarter of fiscal year 2016 to be 35.5% before any discrete items and if the rates in our taxing jurisdictions remain generally consistent throughout the year.
Cash flow generated from operations for the first nine months of fiscal year 2016 was an impressive $243.9 million, an increase of $85.7 million or 54% compared with the prior year.
We did an excellent job this quarter of managing operating working capital defined as receivables plus inventories less payables as our operating working capital net of the effect of acquisitions decreased by one day compared with last year's of 41 days which we believe is industry-leading.
In the first nine months of fiscal year 2016, we spent $61.8 million on capital expenditures compared with $42.3 million in the prior year.
This uptick in capital expenditures is primarily due to investments necessary to support our growth including tooling for new products, expansion in our electronic capacity and building out of our innovation and technology center in Metro Atlanta which we moved into earlier this fiscal year.
We currently expect to spend approximately 2.5% of revenues in capital expenditures in fiscal year 2016.
At May 31, 2016, we had a cash and cash equivalent balance of $337 million, a decrease of $419.8 million since August 31, 2015.
This decrease was primarily for cash used to fund acquisitions of $613.7 million and capital expenditures of $61.8 million as well as to pay dividends to shareholders of $17.1 million.
Our total debt outstanding was $354.4 million at May 31, 2016.
The ratio of debt net of cash to total capitalization net of cash was 1.1% at May 31, 2016.
We had additional borrowing capacity of $243.9 million at May 31, 2016 under our credit facility which does not expire until August 2019.
We clearly enjoy significant financial strength and flexibility and will continue to seek the best use of our strong cash generation to enhance shareholder value.
Thank you and I will now turn the call back to Vern.
Vern Nagel - Chairman, President and CEO
Thank you, Ricky.
As we look forward, we see significant long-term growth opportunities that are ever changing and evolving in a positive direction for Acuity.
Last week's UK referendum vote to exit the European Union has created a great deal of uncertainty and generated significant volatility in the global financial markets over concerns regarding the potential impact if any on the global economy.
This uncertainty and volatility have the potential to affect consumer and business sentiment which could negatively impact global economic activity.
This notwithstanding, we remain bullish regarding the Company's prospects for continued profitable growth so while we don't give earnings guidance, I would like to provide a few observations.
First, the consensus estimate from independent third-party forecasters calls for the broad lighting market in North America which represents 97% of our total net sales to grow in the mid to upper single-digit range through fiscal 2016 reflecting the benefits of both new construction and renovation activity.
Again, the favorable trend in our June order rate seems to support this continued level of improvement.
Further, we continue to see signs that give us optimism regarding the future growth of the markets we serve in our business.
Leading indicators for the North American market such as architectural billing index, vacancy rates, office absorption, lending availability and favorable employment trends continue to improve at varying paces while residential construction continues to grow nicely.
Excluding the price of certain LED components which are expected to continue to decline and fuel costs which have risen recently, we do not anticipate significant changes in most input costs over the next 12 months.
We expect to offset the impact of rising fuel prices through certain pricing initiatives and product cost reductions.
Further, we expect employee-related costs to continue to rise primarily due to increases in associate headcount, wage inflation and the negative impact of rising healthcare costs.
Next, we continue to be leery of foreign currency exchange rate fluctuations particularly during this period of uncertainty caused by the UK announcement last week.
Another observation, while our gross profit margin is influenced by a number of factors including sales volume, innovation, price product and sales channel mix as well as current dilutive impact of Juno, we expect our annual gross profit margin to continue to improve over time as volumes grow and as we continue to realize typical gains in manufacturing efficiencies including cost savings related to the integration of recent acquisitions.
Our record adjusted gross profit margin for the first nine months of fiscal 2016 is a good example of our potential.
It is a positive picture.
Additionally while we always experience some isolated pricing pressures in various markets and sales channels, we will continue to be vigilant on pricing.
As we have said before, we will defend our market position vigorously from competitors should they attempt to use price as their only point of differentiation.
Lastly and most importantly, we expect our growth rates to continue to meaningfully outperform the markets we serve.
Looking more specifically at our Company, we are very excited by the many opportunities to enhance our already strong platform including the expansion of our Tier 3 and Tier 4 holistic lighting and building automation solutions that for example connect smart lighting with smart phones for retailers as well as our growing electronic component and software capabilities.
We are experiencing strong interest from many of our key customers for our holistic solutions with these capabilities and more.
As I noted earlier, we expect to quadruple our installed base by the end of 2016.
As we have noted in the last several conference calls, the implementation of our integrated tiered solution strategy and our opportunities to meaningfully participate in the interconnected world is really a continuation in the advancement of our overall growth strategy which has been in place for some time.
This includes expected benefits from the acquisitions of Distech which we believe will meaningfully expand our addressable market and add much greater opportunities to offer customers even more broad-based holistic solutions to optimize the performance of their facilities.
While we are very early in this game, we are seeing positive results in our growth rates for Tier 3 and the implementation of our IoT solution.
Further, we expect the addition of Juno to meaningfully expand and strengthen our lighting solutions portfolio including both down and track lighting as well as enhance our presence in the residential and corporate account sales channels.
As we noted in our last earnings call, while we are extremely bullish on the long-term growth potential of the Juno Lighting Group, we experienced a modest short-term impact of their net sales as we integrated certain overlapping sales forces.
We are pleased to report the integration of those sales forces has been substantially completed and early indicators such as quote rates for Juno products are up significantly over the year-ago period.
This gives us optimism that much of the negative impact of a sales force integration is behind us.
Lastly, the addition of Geometri, a small yet fast-growing business intelligence company will enhance our expanding business analytics capability as part of our software solutions portfolio to support retailers and other building users' need for actionable data.
The addition of Geometri will meaningfully enhance our Tier 4 solutions offering and is already paying dividends through greater customer connectivity.
Our Company-wide strategy is straightforward, expand and leverage our industry-leading product and solutions portfolio coupled with our extensive market presence and our considerable financial strength to capitalize on market growth opportunities that will provide our customers with unmatched value and our shareholders with superior returns.
This all takes focus and resources.
We are investing to enhance and expand our core competencies to excel in our fast-changing industry because we see great future opportunity.
Through these investments, we have significantly expanded our addressable market.
Our record growth supports this view.
As I have said before, we believe the lighting and lighting related industry as well as the building automation systems market will experience significant growth over the next decade because of continued opportunities for new construction and more importantly, the conversion of the installed base which is enormous in size to more efficient solutions particularly as energy and environmental concerns come to the forefront along with emerging opportunities for digital lighting to play a key role in the Internet of Things.
We continue to believe the many markets we serve as part of the broader lighting and building automation industries, some of which could grow by 50% over the next few years will provide us with significant growth potential.
As the North American market leader in lighting solutions and a technology leader in building automation, we are positioned well to fully participate in these exciting and growing industries.
Thank you and with that we will entertain any questions that you have.

John Walsh, Vertical Research.
John Walsh - Analyst
Hi, good morning.
I was wondering if you could talk a little bit about the acquisition pipeline and then kind of wondering also about some of the volatility we are seeing in Europe, if that kind of opens an opportunity to do something there or if you feel you need to wait for the market to normalize a bit before you would do anything in that market?
Vern Nagel - Chairman, President and CEO
So Ricky, why don't I take the second part first and then you comment on acquisitions.
Our strategy in broad Europe is really twofold.
We have a very strong brand in both industrial and Roadway as well as other types of indoor capabilities.
So we will continue to drive our productivity, our focus in those markets with those products.
We focus on the UK, we focus on Germany, Northern Europe.
We have a capability in Spain and my sense is that while there is a great deal of uncertainty going on right now which could have some impact on our order rate, we still think it is a bullish opportunity because of what certain markets and certain countries are doing in terms of their industrial output.
So while Europe represents or sales outside of North America represent really only 3% of our total, we continue to like the strategy that we have in Europe and that is to focus on key customer sets, key channels with key products that we have and maintain our capability there.
If there are opportunities that come up we will look at them but they have to be very consistent with our strategy.
In terms of acquisitions overall, we continue to see a very interesting pipeline.
Ricky, why don't I ask you to comment.
Ricky Reece - EVP and CFO
We continue as Vern said to see a very robust opportunity for acquisitions.
Our focus is in two primary areas, technology and there we continue to see opportunities not only to acquire but to make investments in, minority or larger investments in, or to partner or lastly to just have a commercial relationship to share technology on a licensing type arrangement.
So we do see a lot of opportunities there and continue to be very active in pursuing opportunities to expand our capability and technology.
The other area is in bolt-on, tuck-in type acquisitions both for our luminaire business as well as our control building management business.
There too we are seeing a robust pipeline.
Obviously Juno is a great example of a bolt-on, tuck-in type acquisition that fills gaps that we have.
There we are more likely obviously to look to acquire as opposed to invest in.
But we do see a robust pipeline and I think it is likely in both of those areas to continue to see us be active where it supports our strategic focus and creates value at a reasonable price.
Vern Nagel - Chairman, President and CEO
As everyone knows, we are very disciplined in terms of the acquisitions that we make, transactions have to be both desirable as well as doable from a financial perspective.
So it is difficult to precisely determine the exact timing of acquisitions but suffice it to say that as part of our strategy for growth, we will continue to look for these types of opportunities as Ricky described.
John Walsh - Analyst
Okay.
Just on the second question, are there any metrics that you can share about driving the Tier 3, Tier 4 solutions growth either the amount of headcount that has been added to sales and engineering this year and kind of expectations into next year, how you are going to drive that initiative?
Vern Nagel - Chairman, President and CEO
Sure, in my prepared remarks I said that Tier 3 solutions through the first three months and again coming off of a smaller base and our measuring capabilities in the prior periods weren't as robust as they are today, but we guesstimate that Tier 3 portion of our business which now represents almost 10% of our business grew at approximately a 40% growth rate.
When we think about how we have invested in our tiered solution strategy, our headcount including acquisitions this year is probably up in the salaried headcount area close to 30% and while we don't specifically allocate all capabilities by tiers because of the way products can work and migrate through the tiers and support the tiers, it is not really an effective use to allocate.
But what I can say is that when we look at things specific to our tiered solution strategy like our ability to develop software whether it be firmware that makes our entire Tier 3 solution work well between various control components, Distech of course and our lighting business, that group has expanded by a factor of four.
We probably had 18 months ago less than 20 folks in this group, today we have over -- we are approaching 80 folks and by the end of the year we will probably have close to 100 on our way probably to 150 people.
And it is really because of the opportunities that we see in supporting the Tier 3, Tier 4 solution set.
We are very pleased to announce that Target selected us as their exclusive smart lighting solutions provider, the opportunity to provide them not only with lighting solutions that enhance energy efficiency but provide them with other opportunities to do things is really an example of how we are -- not moving -- but investing in and growing our Tier 3 solution strategy.
So more to come.
We are in the very early innings of this game and we are very excited about the potential of what this tiered solution strategy will afford for you as shareholders and for our customers and (technical difficulty)
John Walsh - Analyst
Great.
Thank you for the color.
Operator
Tim Wojs, Baird.
Tim Wojs - Analyst
Good morning, nice job.
I guess just going back to Target, is there any way to maybe kind of put some numbers around just the revenue opportunity?
I think you said that the number of beacon enabled light fixtures is going to quadruple by the end of the year and just maybe some rough math, that could add a couple of points to revenue growth.
So just want to make sure that maybe I'm in the ballpark in terms of how we should think about the Target win financially?
Vern Nagel - Chairman, President and CEO
As you might imagine, the opportunity at Target, the initial opportunity is somewhat -- I mean interesting in that they will build out I think the number is probably north of 300 stores over the next three or four months.
I think what is more interesting than trying to put a numerical number around it and it is not just Target, it is the whole notion of how the installed base, not just in retail but when you think about other very large building owners whether it is campuses or universities or research centers, these large installed bases, the opportunity to convert them from traditional lighting to smart lighting solutions really is not only for energy savings but daylight harvesting, the ability to make the visual space better, more effective, the opportunity to participate in the Internet of Things as data collection points.
That is what we find really fascinating.
So our relationship with Target is a decades-old long relationship.
They are a great customer and we dedicate significant resources to making sure that we are meeting their needs at every step.
So it is an example of our access to market and then bringing the solution sets to the market that are allowing us to drive Tier 3.
So when I think about the total market, DOE says there is 100 billion square feet of building space that is in the US, 70% of which was put in place before 1990.
A few years ago we estimated that to convert that installed base might have been about $3 a square foot for lighting and controls.
Today we believe that number is much higher because of the true value add that can be brought through smart lighting.
The Target situation is just an example and there are many, many, many more.
Without focusing too much on Target, we are focusing on what Target represents as a leader in the retail space and taking a leadership position to make the conversion to smart lighting, I think that is what is really interesting.
And then how that expands and extends to other folks that are different subsets of the retail market which as you know is huge, so that they can take advantage of smart lighting, that is the potential.
I think that the market that is out there, that installed base is enormous in size and represents an enormous opportunity for Acuity as we go forward.
Tim Wojs - Analyst
That is great.
Would you say that over the last maybe even year to date that the number of conversations that you are having with retailers is starting to accelerate?
Vern Nagel - Chairman, President and CEO
Absolutely.
It is not just retailers, it is users of space that are looking to optimize how they use the space, not just from an energy-savings standpoint but how can quality of light enhance what they are doing, how can these luminaires that can be enabled in a much more effective way.
Today you still have technologies that are out there that are using battery-powered beacons and somehow they are trying to say that that is the equivalent.
It is really a shame because that old technology, those old solutions that people are saying I have that too, it is really not the same.
And as people become more comfortable and understand the solutions set, what Acuity offers is really huge.
The introduction of nLight Eclipse for example, is just another example of a Tier 3 solution set that allows us to get after building owners, not just retailers but all building owners in a way that allows us to optimize their lighting while driving great unification between the HVAC systems, sub-metering, security and lighting and allowing us to do this in a very, very clever and simple way.
It doesn't exist in the marketplace so we are excited about that whole approach to the installed base because of its size and scale.
Tim Wojs - Analyst
Okay.
And then just my second question, just on the restructuring and the streamlining expenses that you called out, should we think of that as incremental to the mid to high 20% incremental margin target that you have out there or is it kind of included in that target over the next year?
Vern Nagel - Chairman, President and CEO
The opportunities that we have to continue to direct investment in our business, we are looking for ways to continue to hone how we approach the market, the investments that we make and some of those are difficult decisions of what we are not going to do because there are still some market.
But we see so much potential in again Tier 3 and Tier 4 and what it can mean for that installed base.
We will continue to direct investment and continue to drive productivity in our business and I will consider this a productivity opportunity where we can continue to invest.
This quarter we delivered on the legacy business about 30% variable contribution so it is higher than what we kind of had been targeting into that mid to upper 20s.
So we are always looking to optimize in the short term what we are doing in terms of variable contribution margin so we can drive our results but we are doing that against the backdrop of long-term investment opportunities and for us mostly that is human capital.
We are spending right now on CapEx about 2.5% of sales, a little bit higher than what we normally do but we are still investing at a very rapid pace in our human talent.
As I mentioned earlier including acquisitions, our salaried headcount is up about 30%.
But interestingly, our SDA as a percentage of total sales we picked up about 10 basis points.
So we are looking to leverage our base while investing.
So to say precisely that all of those savings are going to enhance variable contribution, we are looking at balancing off both investing for the short term as well -- excuse me -- investing for the longer-term while investing or delivering shorter-term results.

Thanks for taking my questions.
First I wanted to ask in terms of you are (inaudible) today new construction and renovation market.
What kind of growth rates are you seeing in new construction versus renovation side and are there any verticals in the market which you see accelerating or decelerating currently?
Vern Nagel - Chairman, President and CEO
Sure.
Overall we believe that our mix of business is tilted -- we guesstimated 50% renovation, 50% new construction.
It is probably tilting a little bit more towards renovation and I would see that over time it may even tilt more because the installed base is so enormous.
And the opportunity there is to provide value and solution sets to end customers where there is no alternative, they are not building something, they are not renovating.
We call that unplanned renovation.
But it is because the payback and the opportunity of the new solution set is so compelling that they want to make that unplanned renovation.
I would say new construction continues to move along at a solid but yet somewhat of a -- almost a schizophrenic pace.
We see spurts and then we seek declines, we see spurts and declines and that has to do with the entire geography because we serve so many different markets.
It is difficult to discern an absolute trend.
There is no doubt that when we went through here over the last 18 months, changes in oil prices that some of the activities in those oil patch areas slowed down a little bit but yet in other areas, technology, we see those markets continuing to expand.
So I feel generally speaking that as employment continues to improve, we are seeing broad-based improvement in commercial office buildings, we are seeing improvements in healthcare as budgets of states continue to improve, we are seeing spending on education, both K-12 as well as higher education.
The industrial segment continues to move along nicely, roadway seems to be moving along quite nicely.
So I think all in all we are continuing to see improvement on a gradual basis but it is the renovation market that allows us to continue to drive our growth in a solid way.
Europe, we will wait and see what happens there.
Obviously that uncertainty is out there but I don't feel like the contagion of anything that may go on there will spill over here.
Just to reiterate, 97% of our revenues are generated here.
We have a great business in the UK and in Spain.
Obviously UK's products just got a heck of a lot cheaper for people to now acquire them in Mainland Europe.
So we continue to be bullish on the overall opportunities for Acuity.
Sven Eenmaa - Analyst
Great to hear.
The second question I wanted to ask was regarding your integrated solution which now you can provide both the Distech acquisition including lighting controls and HVAC and obviously you mentioned security as well.
There are obviously already established competitors in those markets but curious to understand like which verticals or which market segments do you see for US, kind of the lowest hanging fruit or where do you expect to make the fastest headway there?
Vern Nagel - Chairman, President and CEO
Sure.
So if you look at Distech and Distech is a technology control company and so it is not really selling hardware components.
So when you remove that and you look at people who are selling software control solutions, Distech has -- while it is a smaller business, it has a very strong reputation for being innovative using technology.
It has a reasonable market share and so the opportunity for us to work with and have two channels, their traditional channels system integrators and our traditional channel of local agents work to sell these solution sets that really provide a great deal of value for really buildings of all types and really explain why using our now unified system which we are very excited about.
It is software, it took a lot of time to develop, a lot of hard work but the nLight Eclipse system will be the backbone in terms of creating a very, very simple single piece of glass for building users to now manage the affairs of their building in a much more simple and effective way.
So we are very excited about the possibilities and the opportunities of that because its applicability -- again think of education, campuses of any type, commercial office buildings, healthcare facilities and you can just keep going on.
Buildings of any type are really the opportunity here and given the connectivity that we have through contractors, engineers, lighting designers, and they through system integrators and then their own form of contractors, this will allow us to sell those value propositions.
And the ease of installation, the ease of programming is really going to be a point of key differentiation and then the end-user has very, very simple tools or simple to use but massive tools that are available to help drive the effectiveness of their building.
Sven Eenmaa - Analyst
Great, thank you.

Jeff Osborne, Cowen and Company.
Jeff Osborne - Analyst
Good morning and congratulations on the results.
I just had two quick questions.
One, on the 2% price mix; that is a little higher than recent quarters.
You had alluded to on the call that the driver of that was the LED component and other component price declines, but I just wanted to get a sense of was there a pickup there or was your reductions in price somewhat of a catch-up or where there competitive aspects at play?
Any color would be helpful.
Ricky Reece - EVP and CFO
I would say it is a slight pickup.
We have been saying 1%, so it is a slight pickup with rounding.
We have seen a kind of trough in not just LED components, which is the primary driver of that, but still in other areas that kind of hit a trough and there is a little bit of lag of when that gets in pricing that I think impacted that.
Those kind of cost reductions in commodities such as steel, aluminum, copper, do get passed on pretty quickly in our industry.
Now, as many of you know, steel has taken a quick V-turn -- not even a U-turn, a V-turn -- based on the tariffs that have been imposed on steel to where we have seen steel rise 35-something-percent here in the last few months.
So it would be interesting to see how quick the market reacts to passing that on.
Historically, they've been -- the industry has passed that on.
But I would say it is still predominantly due to passing on reduction in our input cost, predominantly LED, but we have seen some reduction in others that have caused that number to round to 2% instead of the 1%.
Jeff Osborne - Analyst
Got it.
Thanks for that, Ricky.
Then, Vern, for you.
You mentioned target over the next three to four months roughly 300 stores.
I think you also in your prepared remarks alluded to two other retailers, which I imagine you are limited in what you can -- at least naming them, but can you just give us a sense of scope?
Is the timeframe for rollout a similar timeframe, as well as scope and size of the number of stores?
Vern Nagel - Chairman, President and CEO
Again, we are working with multiple end customers and multiple different verticals.
We don't have specific dates, but my two cents is that, based on the question that we had earlier, the activity and the interest level is increasing at a very high rate and our ability to position ourselves and to have dialogue with these various end customers is robust.
Retailers are very, very focused on the quality of light in their stores, they are very focused on energy savings, they are very focused on these types of things so the transition from conventional florescent lighting into LED while it is very interesting, they are doing it because they see multiple opportunities around it.
I mentioned Target only by way of example and when you think about the installed base, and I want to keep bringing us back to that, it is so enormous in terms of potential for conversion that this is where our excitement is.
It is not, for the investing public, you guys said will give us some evidence that Tier 3 solutions that their strategy could work.
Our growth there has been quite significant as a percentage of our sales.
It is now becoming significant.
This was a customer that made a move.
It is a continuation of the margin towards the huge opportunity that is out there.
So you are right, I am not going to mention other names but what I want to make sure investors understand is that the opportunity through all of these verticals is quite enormous and so we are looking at all those verticals and we are attacking them as we have with vigor and we are selling the solution sets.
We believe we have great sales forces that know how to sell these types of solution sets.
So it gives us a leg up in making sure that we are first.
I would expect us to continue to outperform the growth rates of the markets we serve because of these types of opportunities.
Again, the installed base is enormous.
It is much larger, could be substantially larger than what new construction represents for a long time to come because of its size and its scale.
That is where I would like to direct your attention and your focus.
If you look at what our growth rates have been over the last 13 quarters, double digit growth rates.
We have outperformed the growth rates of markets we serve.
We are doing a good job bringing the margin to bear.
People have asked us about margins you have in the Tier 3.
Just a quick comment.
If I look back over the last three years where we have been implementing this tiered strategy approach, we've picked up close to 400 basis points on our gross profit margin and almost 500 basis points on our operating profit margin during that time period.
So while lots of things are happening to improve our business as we migrate and as we expand is probably a better word in our Tier 3 solution strategy, you are seeing how it is influencing in a favorable way our margin impact and while we are investing.
This has been a continuous comment that we have made.
We are investing today because we see the opportunity tomorrow.
We started that a while back and you are seeing the return and the benefit off of that.
Our cash flow return on investment still is in the low 30 percentile which puts us in the 95th percentile in terms of performance capabilities there.
I think we are doing all this right.
Jeff Osborne - Analyst
Perfect.
Thanks much.
Operator
Brian Lee, Goldman Sachs.
Brian Lee - Analyst
Thanks for taking the questions.
First one was on pricing, it does seem like ASP declines have been more moderate than a lot of people have been expecting particularly on the LED side given the component declines we have seen.
So just wondering does this have to do with your product mix simply getting better as part of the tiered strategy and masking the blended ASP declines or are there some other drivers behind this?
And can you also comment on what the sustainability of the trend is medium and longer-term in your view?
Vern Nagel - Chairman, President and CEO
I think Acuity has done a very good job for a long time of really focusing on continuous improvement, driving productivity gains throughout the business.
Just simply because pricing of componentry comes down, as Ricky key pointed out earlier, it can find its way back in the market.
We deal in a bid world but we are all trying to differentiate or at least Acuity is trying to differentiate its features and benefits relative to the price.
I think we have been successful in convincing our customers of the true value of the solution set that we bring.
Again, when we are up against competitors that are bringing battery-powered beacons to the marketplace, that is old news.
People who are installing that type of technology are making a huge mistake.
It is almost irresponsible of them for them to do that.
The fact of the matter is that Acuity continues to drive that productivity, drive the change in its value proposition so that it can continue to extract the value of a gross profit margin if you will for that value.
I expect that the trend to continue.
We tend to look at gross profit over annual periods, not quarterly periods.
I know that you all have to look at everything on a quarterly basis but I think if you look at that type of thing over an annual basis, you will see that continuous improvement in our business is allowing us to improve margins.
Volume, as that increases, we are able to extract that variable contribution.
Mix, as we continue to grow Tier 3. But let's be clear, Tier 1 and Tier 2 are critically important and we do well there as well in terms of margin profile.
But there is no doubt that Tier 3 and Tier 4 have gross profit margin dynamics that are accretive to what we are doing today.
So we would expect to see that trend continue.
The pricing as Ricky pointed out earlier on component costs, that is ebbing and flowing, it is something that we have always had to manage and what is more important about it is if you can continue to have improvements, even incremental improvements in technology and that goes back into the florescent world.
Just imagine when it went from T12 to T8 to T5.
Same scenario.
So simply because it is an LED light source, it hasn't really changed how we think about the internal workings of our business and how we compete in the marketplace.
We are always trying to sell value.
The new technology, LED is an enabler for us to selling more value, i.e., Internet of Things, combined solution sets for energy savings, that is how we are driving the value and I expect the trend to continue.
Brian Lee - Analyst
Great, that is super helpful.
Second question was just on the market itself.
Recently the DOE released some LED penetration statistics for the US lighting market for 2015.
If you look at the data it looks like resi has been slower than expected but commercial and industrial has been tracking better and then outdoor was most penetrated at I think a bit over 20%.
So wondering how do those trends compare to what you are seeing in your business?
And then on outdoor specifically, I know there has been a lot of talk about the retail channel and building automation but can you give us some sense of whether the higher penetration in that particular vertical is expected to lead to more moderate growth and then what your exposure is there specifically versus some of the other end market categories?
Thank you.
Vern Nagel - Chairman, President and CEO
I can only comment on our outdoor business and that continues to grow at a very nice pace.
We are actually gaining share nicely there.
Our growth rates are exceeding the overall growth rates of the market.
The reason for the penetration in outdoor is it is a total cost of ownership type of thing.
The whole notion of whether it is an industrial outdoor or whether it is a street or a roadway, these luminaires are very expensive to have to change light bulbs and maintain.
So LED is a perfect opportunity to in fact bring value there.
So the penetration rate of outdoor makes complete sense to me and I expect that to continue.
But let me remind everyone, it is still only 20%.
There is another 80% that is out there and that 80% market continues by itself just in outdoor to be an enormous market by itself.
In other areas of the business, we are very excited about the introduction of nLight Eclipse and other components off of that.
The ability to -- we will have some more comments on this later -- the ability to separate meter we believe is going to allow Acuity with its lighting solution and its building automation solution to get after that commercial office market, the installed base which has converted, very, very slowly primarily because most commercial buildings are socialized utilities.
So it is hard to actually get down to what are you consuming in terms of energy, you just pay it based on square footage.
So we are very excited about the potential of converting that type of market as we go forward.
Ricky, other end markets I would say, we see again continued opportunities for further penetration.
I think that the notion of what retail is doing, retail is looking at not just energy savings but what more can occur there.
That is a big space.
Ricky Reece - EVP and CFO
I would just acknowledge the obvious that wherever there was an incandescent light source in the commercial world that it is converting much more quickly than the florescent when you get into as you mentioned indoors converting slower, offices that have florescent.
If you have upgraded to high output T8 or T5, that is still a very energy-efficient light source so the conversion is slower but you are now seeing LED pulling away from the lumens per watt and the capability of florescent so I do think it will accelerate there.
We are very well penetrated in that indoor space and would expect to fully participate as that conversion accelerates.
But where it has been the fastest to date is more where you have had energy sources that were less energy-efficient, incandescent, high pressure sodium, HID that had issues not just energy but slow to come on, hard to control, those type of things that are driving this conversion.
Vern Nagel - Chairman, President and CEO
Lastly, on the retail side I believe that folks early on found replacements to be expensive.
I think that their level of satisfaction with them was not as robust.
I think more and more folks are finding that replacement kits are a more effective way to do things within their home.
They work better, they meet the specifications of long life that they are supposed to.
If you put a bulb in a can that wasn't made to handle that kind of bulb, chances are you are going to get significantly less life than what the manufacturer may advertise.
So we don't sell bulbs but we obviously create kits that are very cost-effective and very, very efficient.
That portion of our business continues to grow very nicely.
So I believe this conversion whether it happens five years, 10 years, 15 years or 20 years is just a huge, huge market and an opportunity for significant growth over time.
