Good morning and welcome to Acuity Brands' fiscal 2016 fourth-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, Treasurer & Secretary
Thank you and good morning.
With me today to discuss our fiscal 2016 fourth-quarter and full-year 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 www.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 risks and uncertainties such that actual results may differ materially.
Please refer to our most recent 10-K and 10-Q SEC filings and 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 the call over to Vern.
Vern Nagel - Chairman, President & CEO
Thank you, Dan.
Good morning, everyone.
Ricky and I would like to make a few comments and then we will answer your questions.
First, let me say we are very pleased with our performance in 2016.
We achieved record results for virtually all financial metrics, including net sales, operating profit, diluted earnings per share and cash flow generation.
For the full year and the fourth quarter, net sales grew approximately 22% while sales volume, excluding acquisitions, was more than double the estimated mid-single digit growth rates of the key markets we serve.
In fact, this was the 14th quarter in a row where we achieved double-digit volume growth, a remarkable achievement that few companies can claim.
We believe these results are yet again strong evidence our strategies to deliver superior returns to shareholders, provide customers with differentiated value-added solutions and diversify the end markets we serve are succeeding allowing us to extend our leadership position.
These strategies include the continued aggressive introduction of innovative energy-efficient lighting and building management solutions, expansion in key channels and geographies, improvements in customer service and companywide productivity.
We achieved record profitability for the quarter and full year even as we've continued to invest in areas to support our strong sales growth, as well as opportunities with significant future growth potential, including the expansion of our digital lighting and building management solutions portfolio, which affords us a huge opportunity to be a critical part of the backbone for enabling the Internet of Things.
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.
First, for the quarter, net sales for the fourth quarter were a quarterly record of $926 million, an increase of 22% compared with the year-ago period.
Our net sales could have been even higher as I will explain later in the call.
Reported operating profit was $135.1 million compared with $111.8 million in the year-ago period.
Reported diluted earnings per share was $1.89, a quarterly record, compared with $1.37 in the year-ago period.
There were adjustments in both quarters for certain special items, which Ricky will explain later in the call.
Also, our reported financial results included certain items, among others, 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.
Because many shareholders and analysts ask specific questions regarding these items in order to make our results comparable between periods, we will continue to add back these items to our reported results to provide greater transparency and comparability.
In adding back these items, one can see adjusted operating profit for the fourth quarter of 2016 was a quarterly record of $156.5 million compared with adjusted operating profit of $123.6 million in the year-ago period, an increase of 27%.
Adjusted operating profit margin was 16.9%, an increase of 60 basis points.
Adjusted diluted earnings per share was a quarterly record of $2.21, up 27% from the year-ago period; again, strong quarterly results.
For the full year, net sales at Acuity were a record $3.3 billion, up 22% from 2015.
Reported operating profit was $475 million in 2016 compared with $376 million in the year-ago period, while diluted earnings per share was $6.63, up 30% from the year-ago period.
Adjusted operating profit was $555 million in 2016, up 32% from the year-ago period.
Adjusted operating profit margin for the full year was a record 16.9%, up 130 basis points compared with the prior year.
Adjusted diluted EPS was a record $7.84, up almost 35% from 2015.
In addition, we generated a record $346 million of net cash provided by operating activities this year, up 20% from last year.
We closed the year with $413 million of cash on hand even after investing $623 million for acquisitions, as well as $84 million in capital expenditures this year leaving us with plenty of financial firepower to execute our growth strategies.
Lastly, I'm pleased to report that we once again earned much more than our cost of capital.
Our adjusted cash flow return on investment for 2016 was 34%, tying our all-time high even after the significant investments made this year.
We believe this level of return is far in excess of others in the electrical industry.
For those who follow EVA, we generated over $150 million in positive EVA, an astounding achievement.
To put our performance in perspective, I'd like to remind folks of two points.
First, the nonresidential construction market, an important market for us, is still down about 15% on an inflation-adjusted basis from its peak in 2008 and yet our net sales are up 65% since then.
Second, we sold virtually no LED-based fixtures in 2008 and today, these solutions make up almost two-thirds of our net sales.
We've invested significantly to make Acuity the leader in digital lighting while at the same time delivering superior financial performance for our shareholders.
While our record results for the quarter and the full year were significant improvements over the year-ago period, it could have been even better.
We would like to provide you with more color on our results for the quarter and the year.
Net sales and profitability for the fourth quarter were all-time quarterly records.
However, as I said, our results could have been even greater and here is why.
During the quarter, we made the decision to accelerate certain actions to streamline our supply chain, enhance our customer service and drive productivity.
These actions included, among others, the closure of a manufacturing location and the transfer of certain production to alternate locations in order to free up additional capacity for future growth and to better leverage our overall supply chain.
These actions overlap with the ramping up of a new production facility and the addition of a new paint line.
The combination of these actions created labor shortages in certain locations, which negatively impacted production and shipments, which resulted in canceled orders, as well as added cost.
We estimate these short-term labor issues resulted in canceled orders and loss contribution on more than $25 million of net sales and caused us to incur additional overtime and other costs in excess of $2 million in the quarter.
We are not going to attempt to quantify the impact that these labor shortages had on our fourth-quarter results beyond what I've noted just now.
Please know the actions implemented this quarter will provide significant benefits to our business as we go forward.
While the impact of these labor issues is mostly behind us, we may experience some modest carryover effect into our first quarter, which we do not expect to have a material impact on our results.
Looking more closely at the fourth quarter, net sales grew 22% compared with the year-ago period.
We estimate our sales volume grew an impressive 13%.
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 in 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 productlines and sales channels.
Sales of LED products at Acuity now account for almost two-thirds of our total net sales.
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 management solutions and the strength of our many salesforces have allowed us to yet again achieve meaningful sales growth this quarter.
Before I turn the call over to Ricky, I would like to comment on our profitability and strategic accomplishments.
Our profitability measures for the fourth quarter were outstanding even while absorbing the impact of the supply chain streamlining actions I noted earlier and the continued investments in areas of growth such as our unified lighting and building management platform and our IoT capabilities.
Our adjusted fourth-quarter operating profit was $156.5 million, the most in our history and adjusted operating profit margin for the quarter was 16.9% and just shy of our quarterly record of 17.2%, but up 60 basis points from the adjusted margin in the year-ago period.
Further, our adjusted gross profit margin for the quarter was 43.5%, up 120 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 most of the supply chain and lower input costs partially offset by the addition of Juno, which, in its recent past, has had lower gross profit margins than Acuity, as well as a short-term impact of the supply chain streamlining actions taken during the quarter.
Next, total selling, distribution and administrative expenses, excluding the adjustments noted earlier for each quarter, were up $48.1 million or 24%.
Adjusted SD&A expenses as a percentage of net sales were 26.6% in the current quarter, an increase of 60 basis points from the year-ago period.
The increase in adjusted SD&A expense was primarily due to higher freight and commission costs to support the increase in net sales, the addition of acquisitions and higher compensation costs.
The increase in compensation cost 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 fourth-quarter results were is to examine our variable contribution margin, excluding the impact of acquisitions.
On a comparable basis, our variable contribution margin as a percentage of net sales was approximately 26%, well within our current target of mid to upper 20%s.
All in all, we had another great quarter.
The story was much the same for the full year's record sales results -- full-year record results in 2016.
Net sales grew 22% this year.
Excluding acquisitions, our net sales grew over 13% while sales volume grew over 15%, more than 2 times the estimated growth rate of our addressable market.
Adjusted gross profit margin was a record 43.7%, up 140 basis points compared with the prior year's gross profit margin.
Adjusted operating profit margin of 16.9% improved 130 basis points over 2015.
Our adjusted variable contribution margin for the full year, excluding acquisitions, was almost 30% even while we invested aggressively in areas which represent exciting growth opportunities.
Again, we had another great year.
On the strategic front in 2016, we continue to make great strides setting the stage for what we believe will be a strong growth in profitability in 2017 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 control solutions, as well as our building management platform.
With the addition of Juno, we now offer customers more than 1.8 million lighting SKUs to choose from, more than 3 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 that also support building management and IoT applications.
Innovation continues to be at the forefront of our strategy, winning accolades from customers and numerous industry awards this year for introducing solutions never seen before.
In fact, Forbes magazine recently recognized Acuity Brands in its top 100 Most Innovative Companies list.
No other lighting company or building management company made this exclusive list.
This is a remarkable achievement for our extraordinary associates.
And remember, this is from a company with longtime industry-leading brands, one of which has been in existence for almost 120 years.
Additionally, we continue to invest and expand our capabilities to drive our integrated tiered solution strategy, which consists of four tier levels.
As we have noted before, the purpose of this strategy is to leverage our incredibly diverse and growing portfolio offering customer 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 management solution, 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 and to use.
These are compelling and powerful value propositions for customers and a competitive advantage for Acuity.
And the additions of Distech, Geometri, DGLogik and Juno in 2016 have meaningfully enhanced our industry-leading capabilities and solutions portfolio.
While sales data for our tiered solutions is still imprecise and expanding off a small base, we believe sales in our tier 3 category encompassing our holistic, integrated solutions were up almost 40% this year over 2015 and now represent more than 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 recurring revenue streams, which we identify as tier 4 solutions.
To fully execute our holistic tiered solution strategy, we have continued to hone our organizational 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 salary and headcount to support the growth as part of this overall tiered solutions strategy.
In fact, our salaried headcount is up over 30% from one year earlier.
That includes acquisitions.
Few other companies, if any, have been able to make this kind of investment while delivering upper-quartile financial performance like Acuity.
Additionally, now that LED is widely accepted, the attention of customers is focused on how they best can control and utilize this light source to optimize their visual environment while realizing additional benefits, including energy and maintenance 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 additions of Distech, Juno, DGLogik and Geometri, we believe we are uniquely positioned to grow much faster than the markets we serve.
At Acuity, we are not just talking the Internet of Things, we are doing it.
As I noted last quarter, we had converted over 12 million square feet of space for customers, including global leading retailers and certain other customers to smart lighting solutions.
As part of their smart lighting solution platform, we had more than 200,000 maintenance-free beacon-enabled lighting fixtures that are performing superbly collecting data and enabling applications that provide users with a superior lighting and energy performance, as well as useful, actionable information.
Importantly, we are on a path to almost quadruple this installed base by the end of calendar 2016.
We believe this level of capability and deployment is unmatched in our industry.
The integration of Distech, which operates in its historical markets as more of a standalone company, continues to move along very well.
We expect the combination of Distech and Acuity with our broad industry-leading solid-state lighting portfolio, innovative control technologies and integrated digital solutions 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 reductions, 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.
As an integral part of this strategy, we just introduced nLight ECLYPSE, 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 solutions that have unified lighting, HVAC, power metering and security.
This solution set streamlines our building program, facilitates our smart multi-zone daylight harvesting and color tuning capabilities and enhanced 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 is driving the evolution to smart buildings and smart cities and we are just getting started.
We expect our recent strategic acquisitions, coupled with our aggressive internal investments, will allow us to continue to diversify and strengthen our foundation and further serve as a robust platform for our future growth that is less reliant on the new nonresidential construction cycle.
We've been able to produce these results because of the dedication and resolve of our now almost 12,000 associates who are maniacally focused on serving and solving and supporting the needs of our customers.
I will talk more about our future growth strategies and our market expectations for the construction markets 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 2017.
Ricky.
Ricky Reece - EVP & CFO
Thank you, Vern and good morning, everyone.
As Vern noted, we had a solid fourth-quarter and full-year performance on virtually all metrics, including sales and earnings growth, profitability and cash flow.
I will add insight to our financial performance and not repeat the information already provided by Vern.
As Vern mentioned earlier, we had some adjustments to the GAAP results in fiscal 2016 and 2015, which we find useful to add back in order for the results to be comparable.
In our earnings release, we provide a detailed reconciliation of non-GAAP measures.
Primarily due to the impact of the four acquisitions completed in fiscal-year 2016, we experienced noticeable increases in amortization of acquired intangible assets; share-based compensation expense since we used restricted stock as a tool to improve retention and to align the interests of key leaders of acquired businesses with those of the shareholders; special charges as we streamlined and integrated recent acquisitions; and an impairment of intangible assets as we rationalized acquired trade names.
We believe adjusting for these items and providing these non-GAAP measures provide greater comparability and enhanced visibility into our results of operations.
We think you'll find this transparency very helpful in your analysis of our performance.
In addition, many of our peer companies, especially as we become more of a technology company, make these same adjustments, so it will help as you compare our performance to other public companies in our industry.
During the fourth quarter and full year of fiscal 2016, the Company recorded a pre-tax special charge of $4.9 million and $15 million respectively for actions initiated to streamline the organization, including the integration of recent acquisitions.
These streamlining activities included the consolidation of selected production activities and realignment of certain responsibilities, primarily within various selling, distribution and administrative departments.
We realized net savings in excess of $4 million in fiscal year 2016 and expect to achieve annual savings of twice the amount of the special charge, or approximately $30 million, and we believe we will be at this run rate by the end of the second quarter of fiscal year 2017.
We anticipate incurring additional costs associated with further integration activities of recent acquisitions in fiscal year 2017, although the amount and exact timing has not yet been determined.
During the fourth quarter, we finalized our allocation of the purchase price for the Distech acquisition and refined the preliminary allocations for Juno, Geometri and DGLogik acquisitions.
Consequently, we reduced our fourth-quarter acquisition-related amortization expense by $4.4 million from the amount recorded in the third quarter.
We expect to finalize the remaining purchase price allocations by the end of our second quarter of fiscal year 2017.
Our current estimate is that acquisition-related amortization expense will be approximately $5.8 million per quarter in fiscal year 2017.
To provide full transparency of this non-cash cost, we will continue to quantify this amount each quarter as part of our adjusted results.
The effective tax rate for the fourth quarter was 34.8% compared with 35% in the fourth quarter of last year.
We expect the effective tax rate for fiscal year 2017 to once again be 35.5% before any discrete items and if the rates in our taxing jurisdictions remain generally consistent throughout the year.
We did an excellent job this year of managing operating working capital defined as receivables plus inventories less payables as our operating working capital was 38 days, which we believe is industry-leading.
In fiscal year 2016, we spent $83.7 million on capital expenditures compared with $56.5 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 electronics and painting capacity and buildouts of our innovation and technology center and a new production facility, which we moved into earlier this fiscal year.
We currently expect to spend approximately 2.5% of revenues in capital expenditures in fiscal year 2017.
At August 31, 2016, we had a cash and cash equivalent balance of $413.2 million, a decrease of 343.6 million since August 31, 2015.
This decrease was due primarily to cash used to fund acquisitions of $623.2 million and the capital expenditures of $83.7 million, as well as to pay dividends to shareholders of $22.9 million.
Our total debt outstanding was $355.2 million at August 31, 2016, and we had more cash than debt at the year-end.
We had additional borrowing capacity of $243.9 million at August 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 & CEO
Thank you, Ricky.
As we look forward, we continue to see significant long-term growth opportunities that are ever-changing and evolving in a positive direction for Acuity.
Overall, the economy in North America and certain markets we serve in Europe continue to move along at a measured, but sometimes inconsistent pace.
This year's presidential election in the US and events such as UK's referendum vote to exit the European Union continue to create uncertainty and volatility.
This uncertainty and volatility always has the potential to affect consumer and business sentiment, which in turn could negatively impact global economic activity.
That 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 for 2017.
First, we estimate the broad lighting market in North America, which represents 97% of our total net sales, will grow in the mid to upper single digit range in fiscal 2017 reflecting the benefits of both new construction and renovation and retrofit activity.
Again, the favorable trend in our September order rate seems to support this continued level of improvement.
Further, we continue 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 the Architecture Billings Index, vacancy rates, office absorption, lending availability and the 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 steel costs, which we expect to continue to rise, we do not anticipate significant changes in other material and component costs over the next 12 months.
We expect to offset the impact of rising steel 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, which are always unpredictable.
Another observation.
While our gross profit margin is influenced by a number of factors, including sales volume, innovation and price, product and sales channel mix, as well as the current dilutive impact of Juno, we expect our annual gross profit margin to continue to improve over time as sales volume grows and as we continue to realize typical gains in manufacturing efficiencies, including cost savings related to the recent actions taken to accelerate the integration of acquisitions made in 2016.
Our record adjusted gross profit margin in fiscal 2016 is a good example of our potential.
It is a very 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 overall growth rate to continue to meaningfully outperform those of 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 4 holistic lighting and building management solutions that, for example, connect smart devices with smartphones for many different end-users, as well as our growing electronic component and software capabilities.
We are experiencing strong interest from many of our customers for our holistic solutions with these capabilities and more.
And as I noted earlier, we expect to quadruple our installed base of connected devices by the end of calendar 2016.
As we have noted in our 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 our acquisitions of Distech, Geometri and DGLogik, which we believe will meaningfully expand our addressable market and add significantly greater broad-based holistic solutions allowing customers to optimize the performance of their facilities.
While we are very early in this game, we are seeing positive results in our growth rates of our tier 3 and tier 4 categories, as well as the implementation of our IoT solutions.
Further, the addition of Juno has meaningfully expanded and strengthened our lighting solutions portfolio, including both down and track lighting, as well as enhancing our presence in the residential and corporate account sales channels.
We are still in the early stages of fully optimizing the potential of Juno as part of our portfolio.
Our companywide 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 management 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 and effective solutions.
We believe this is particularly compelling as energy and environmental concerns continue to 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 management industries, some of which could grow by 50% or more over the next few years, will provide us with significant growth potential.
As the 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 you have.

Rich Kwas, Wells Fargo.
Rich Kwas - Analyst
Vern, I just want to follow up on the installed base for the network fixtures.
So, on the quadrupling, is it off the 200,000 base, or is that implied that it's off a lower base and that, by calendar year-end, it'll be higher than 200,000, but don't use that as the guide, or the benchmark?
Vern Nagel - Chairman, President & CEO
No, it's off of the 12 million square feet and 200,000 installed light-enabled beacons.
The business, and what we are experiencing there, is just fantastic.
There's interest in many different verticals and so we are in various stages of pilot programs to larger, much larger test programs, all the way to installations.
So it's happening and it's happening at a very interesting pace.
We think that, over the longer term, and please, I don't mean next quarter or the quarter after that, I'm talking pick the next 1,000 days, I think you are going to see a meaningful change and a meaningful adoption of these tier 3 solutions that Acuity is offering and then the opportunity for it to enable tier 4 revenues for Acuity.
We just introduced nLight ECLYPSE, which is a truly, in our view, a game-changing solution set.
It doesn't exist in the industry today where it provides a unified system, not an integrated solution, but a solution set that ties together HVAC, lighting, access, security and also provides a great capability to collect data and push that to the cloud and then push that back through the IoT-type solution set.
So, early, early, early stages of all this, but we are now seeing the growth and it's very exciting for us.
Rich Kwas - Analyst
Okay.
So, ostensibly, you've seen some benefit already, but then it continues to build though is the way to interpret that?
Vern Nagel - Chairman, President & CEO
Yes, (inaudible).
Rich Kwas - Analyst
Quick question on incremental margin as we think about 2017.
So the target has always been mid to high-20%s and you've got some investments going on and you've got restructuring.
So I guess how do we think about the cadence of improvement because the last couple quarters, there's been some noise in the numbers as it relates to costs and whatnot and obviously you had some lost sales this quarter.
So do we think about this rebounding to the mid to high 20%s in a fairly quick manner, or is this more of a gradual recovery as the restructuring benefits play out?
Vern Nagel - Chairman, President & CEO
Well, I think that our variable contribution margins off of, if you will, the legacy business, and we are about to anniversary Juno here December 10, Ricky?
Ricky Reece - EVP & CFO
Yes.
Vern Nagel - Chairman, President & CEO
So those variable contribution margins should continue to roll.
We still have some work to do.
We took actions this quarter that obviously impacted this quarter, but we did that because we really wanted to accelerate both our growth capacity, our capacity to service the growth that we are seeing and will continue to see, we believe; and, number two, to drive productivity so that we can continue to have the type of variable contribution margins that we expect, and what we expect, as we've said before, is that mid to upper 20s%.
That doesn't mean that we won't exceed it from time to time, but this quarter is a great example.
In spite of the challenges that we had with some of the streamlining issues, we still delivered a 26%, 27% variable contribution margin.
For the full-year 2016, we were about 30%.
So our expectation is is that even as we anniversary the acquisitions, we will still be in the very high rate, while continuing to invest.
And just to be clear, these numbers are pretty staggering.
Acuity and its legacy business in the fourth quarter compared to the third quarter, we added 100 people.
We added 100 salaried people.
We are investing heavily because we see huge growth coming our way.
Over the last literally year, including acquisitions, we've added almost 700 salaried heads to our capabilities.
This is an enormous capability.
In the last quarter, we added almost 1,500 hourly people.
Now, that number will come down a little bit as we streamline the operations, but that really was what caused us to experience both labor shortages and just onboarding issues as we ramp up the business because, again, we see very, very robust growth.
All this means that, as we think about 2017, our expectation is to continue to deliver a very robust, variable contribution margin that is in that mid to upper 20% range while investing in our business.
Rich Kwas - Analyst
All right.
Thank you for the color.
I will pass it on.
Operator
Jeremie Capron, CLSA.
Jeremie Capron - Analyst
Thanks.
Good morning.
I wanted to ask about what you are seeing in terms of the regulation landscape here.
Any particular regulations you are keeping an eye on?
And also in terms of incentives in various parts of the country, if you could shed some color on this, it would be appreciated.
Vern Nagel - Chairman, President & CEO
Sure.
Ricky, do you want to take that one?
Ricky Reece - EVP & CFO
Yes.
We continue to see, primarily from utility companies, incentives being offered and as you might imagine, it's being more lucrative in the higher cost areas on both coasts, East Coast, as well as West Coast.
Some of those have diminished a bit from the rates we've seen in previous years, but continue to see pretty aggressive incentives being offered by the utility companies.
And then there are some tax-accelerated benefits as well.
On the regulatory front, continue to see most of the states implementing building codes that mandate certain levels of efficiencies.
Much of it is around the level of control of lights where you need to put occupancy sensors and take advantage of turning lights off in a room, or a stairwell, or in areas not being occupied.
But as in the case of Title 24 in California, you are seeing many of them go beyond that and start mandating how much you are allowed to consume per square foot and the level of integration of the entire office power grid.
So the regulatory front continues to move forward and we see it as another catalyst for our growth.

Great.
Thanks.
Going back to your commentary around incremental margins going forward, can you help us understand the difference in terms of profitability between your higher tiered solutions and the simpler LED solutions because, as you highlighted, the increase in your cost base has been pretty significant yet margins continue to grind up.
I'm trying to understand the mix effect here as tier 3 and over -- it starts to move the needle.
Vern Nagel - Chairman, President & CEO
Sure.
Well, you are seeing our margins continue to improve for a number of reasons.
One, incremental volume; number two, the mix as we migrate more to -- migrate -- as the percentage of what tier 3 and -- tier 4 is de minimis right now, but ultimately we expect it to be a nice margin competitor because you've invested the cost.
It's software-related, so the margins that should come off of that should be very consistent with other companies providing those types of capabilities.
So our expectation is is that our gross profit margin will continue to improve over time and we will be able to continue to leverage as we hit a plateauing probably sometime in late 2017, early 2018 of some of these investments and then the revenues that will be returning off of those will make the percentage of SDA become smaller relative to where it is today.
We finished the year on an adjusted basis with SDA about 26.9%, let's call it 27%.
Margins at the gross profit level were about 43.7%.
Again, our expectation is that our gross profit margins will continue to improve and our SDA we will continue to be able to leverage that.
So the best way to think about our business is still in terms of variable contribution margin.
We are still investing, though the investing is slowing down a tad because we have made significant investments in 2016.
I would also say that when I look at our total cost for salaried associates, as well as our total cost for hourly associates, as a percentage of our sales, those things continue to be flattish and so that's why you are again seeing margins improve over the 2015 time period whether it be at operating profit or at the gross profit level.
So we are getting the leverage.
It's coming through the variable contribution margin and yet we are still investing heavily in our business because again we see really tremendous growth opportunity over the next decade.

So first question I had is is the sales issue from the supply chain fully behind you in September?
Secondly, could you comment on if the September order growth rate is still outperforming the industry?
Vern Nagel - Chairman, President & CEO
I will take the last one first.
The September order rate for Acuity is meaningfully outperforming the industry, as we pointed out.
Number two, your first question, the issue was we knew we were going to have to accelerate the consolidation of some of our manufacturing capabilities.
We knew we were going to have to free up some capacity in key manufacturing facilities, so we decided during the quarter to make that investment, to accelerate those efforts.
And so just the sheer act of ramping up and attracting talent into the organization -- I'm talking about hourly talent -- was a challenge, particularly in a couple of areas because those areas are also experiencing growth from other companies moving into the market.
We knew that was going to happen.
We anticipate it, but truthfully, as we were ramping up, the whole notion of the sheer number of folks that we needed and then the training side of it resulted in us not wanting to ship product because we wanted to make sure that the quality was there and all of these issues.
So we believe that we lost roughly $25 million.
It's an estimate of lost orders and of lost shipments during the quarter and our guess is -- it's just a guess -- that it probably cost us 70 bps of operating profit margin in total.
So you can understand the magnitude, but we had to bite the bullet.
We did it.
We believe it's behind us.
We think there may be some just carryover lingering effect as orders ramp back up.
Our order rate suggests that it's behind us.
Our productive output is pretty close back to where it was in terms of our efficiencies and our effectiveness.
So we are not expecting any of the lingering issues to have a material impact on our first-quarter results.
Ryan Merkel - Analyst
Okay.
That's helpful.
And then, secondly, you are seeing very strong growth of tier 3. It was 40% this year, I think you said.
And based on some of the commentary, it sounds like this growth rate could accelerate in 2017.
Am I reading that correctly?
Vern Nagel - Chairman, President & CEO
Well, I think our mix of business continues to evolve.
We are very focused on selling all tiers and selling value in all of those tiers.
We do well in tier 1 and tier 2 both from a sales perspective, as well as a margin perspective, but the tier 3 solutions, particularly those that are enabled or capable of enabling the Internet of Things, really are very exciting for us and we see more and more people wanting to bring those together.
And truthfully, this is why we introduced nLight ECLYPSE.
It's a very, very powerful lighting, building, automation system that's come together in a way that is unified.
So there's no steps that others have to take.
You don't have to worry about whether the mechanical folks, or whether the electrical folks are going to work together.
That's the beauty of this solution set, and it can enable the Internet of Things and so we believe that more and more folks, as the specification cycle starts its normal routine, we believe that, by mid-year, you are going to see orders ramping up for these things.
So, again, this is what gives us confidence and optimism that we should be able to meaningfully outperform the growth rates of the markets that we generally serve.
Ryan Merkel - Analyst
Okay.
Very good.
I will pass it on.

Good morning, folks.
First, I'm sorry if I missed this, but did you give an update on the Target stores deployment relationship?
I think last quarter we were talking about 300 or 400 stores at least through that quarterly period, but could you give us an update there?
Vern Nagel - Chairman, President & CEO
Sure.
We are on track and things are moving along as expected and very excited about not only what Target is doing, but what other folks, not only other retailers in different subverticals, if you will, but what other verticals are doing.
We have just a whole lot of activity going on in a lot of different places.
John Quealy - Analyst
Okay.
Thanks.
And my follow-up, in terms of the acceleration of some of the footprint issues you did this quarter, the M&A integration at Distech as a standalone, can you talk about your bench strength in terms of being able to integrate more businesses?
Does that limit your M&A appetite in 2017?
If you could just talk a little bit more there.
Thanks, folks.
Vern Nagel - Chairman, President & CEO
Thank you for the question.
No, our acquisition appetite is quite robust.
Whenever you make acquisitions of companies that are add-ons like Juno, for example, it just gives a company like Acuity, which has a robust supply chain, the opportunity to leverage its efficiencies, and so sometimes you have to move things around to be able to do that.
You hope that they always go perfectly.
I think we did a good job.
We just caught a little bit of a perfect storm.
Some of our main facilities are in locations where the growth rate is robust because they are just great locations to be in.
And so as we were ramping up the number of people I had mentioned earlier, just the whole notion of bringing people onboard, training them and facilitating all of that was a challenge, but it was a temporary challenge.
I think few companies have the skill and capability to do it as effectively and as efficiently as we've done.
This was basically a 60-day, 90-day type issue were we've done some meaningful things that will have a huge impact on the profitability of our business going forward, as well as our ability to serve customers and to expand into new markets.
The Distech acquisition and its integration is moving along exceptionally well because they continue to focus on their core businesses.
The engineering departments are working together in a way to introduce solution sets like nLight ECLYPSE.
That's never existed in the market before.
We are meeting an unmet need and it will take a while for those sales to ramp up as the specification cycle works its way through, as we train people, as people become acclimated to it; but, no, our appetite for acquisitions continues.
And while I'm disappointed that we lost some revenues this quarter, I just am very pleased at how aggressively we attack these things because we do see robust growth, not only on the lighting side, but the building management side.
We see growth in the Juno productlines that they brought to us and we see growth in the combination of Acuity and Juno.
So we are very bullish about what we see on a go-forward basis.
Operator

Christopher Glynn - Analyst
Good morning.
With all the industry changes and the repositioning of the portfolio and the project groups to those dynamics to digital lighting controls, maybe some operational disruption was even a little overdue.
Wondering if you could comment on that thought and just around the risk going forward?
I know you already touched on it, but is there any kind of backdrop for legacy product obsolescence and challenges in managing that?
Vern Nagel - Chairman, President & CEO
Chris, that really is not the issue at all.
We always go through product lifecycle management.
I don't see any of this current environment being any different because of how our supply chain works.
We don't have legacy fixed assets because we don't make lamps.
We don't make many things that require heavy investment.
We are a design and procurer and assembler of product to meet our specifications.
So the investments that we have been making have really been to expand, if you will, our physical capacity in some areas because of the growth.
Our electronics business is just on fire.
It's doing exceptional work.
So I don't see any technical obsolescence.
As we think about the moves that we took in the fourth quarter, it was really about training people and bringing people onboard and then stabilizing that process.
We added an enormous number of folks, as I had mentioned earlier in the call, so I think we have managed it exceedingly well.
I wish we had managed it even better.
Typically, we do these things and you, the shareholders, don't really see a blip.
This time, it was pretty big and so the consolidation of what we've done, we believe, will have huge benefits on a go-forward basis.
So, again, I don't really see much in the way of issues.
It's training.
It's development of our people.
We are good at that.
It just happened very, very quickly because we made the decision to accelerate, not go slow, but go quickly because we believe that the growth, particularly on the installed base, renovation and retrofit activity is a huge opportunity for Acuity.
We've introduced some great new products and solution sets to really go after that market even more aggressively.
So we are ramping up our capacity, and we made the decision to do that in a location where it would have its permanent home, not do it in places where it would be temporary.
So that's what caused us to want to accelerate this activity because we see great future growth going forward.
Christopher Glynn - Analyst
Okay.
Just wanted to touch on the idea of using your eldoLED driver or some industry standard potential.
Just wondering how that's rolling out and what the longer-term implications and role of your driver technology are for the portfolio.
Vern Nagel - Chairman, President & CEO
Sure.
That market, like really all markets, it's based on features and benefits and capabilities of your solution set and how you have used technology know-how to create a difference.
I believe that we use other light engines as well from other folks.
So the notion of creating the industry standard is a little different in that we want to offer features and benefits where our eldoLED driver for many of our partners, our friends and we want to enable more, really provides a capability that is unmatched in the industry.
So it's a solution set that people would identify with and by virtue of its features and benefits, we would hope that they would prefer that over others and then, therefore, it becomes the driver of choice for many applications.
As we think about the Internet of Things and how we enable more folks to participate, we want people to use our driver so that it can be part of a holistic system and their capabilities, whoever they happen to be, can participate in a solution set that an architect, a lighting designer, a building owner would like to have, including their luminaires.
I wish I could tell you we make every luminaire known to man.
We don't.
And so our friending strategy is to get others that fill in gaps and have opportunities to participate on the overall system, to be part of that digital backbone and Acuity can then guarantee to the building owner that it's going to work and work the way they want and it will do everything that they want.
So that's really what we are driving towards.
Christopher Glynn - Analyst
Thanks.
And quick clarification.
On the expectation for gross margin to expand over time, I assume that comment applies discreetly to fiscal 2017 as well?
Vern Nagel - Chairman, President & CEO
Sure.
We always are looking to continue to drive and improve our margins.
We have a long history of doing that and our expectations are high for 2017.
Christopher Glynn - Analyst
Thanks, Vern.
Operator
Brian Lee, Goldman Sachs.
Brian Lee - Analyst
Thanks for taking the questions.
Maybe first off, Vern, you mentioned less reliance on non-res new construction during your prepared remarks.
Was hoping you can maybe help quantify that to some degree.
What's your mix today between the new construction and renovation and then how much do you think it could skew toward renovation in fiscal 2017 and then maybe over the longer term?
Vern Nagel - Chairman, President & CEO
Sure.
So, Brian, the way we look at the market is we say there's new construction and we all know well how to do that.
There's an architect, lighting designer, engineer, building owner, electrical contractor, electrical distributor, (inaudible).
The next portion of the market is plan renovation.
That's where someone again will higher architect, engineer, lighting designer and they will go after and they will say I'm going to remodel a wing of my hospital.
Great.
That looks like new construction to us.
Then there's this world of what we call unplanned renovation.
It's what exists out there every day and you use your office every day and you don't think about the lights that are above you.
It's that world that we are looking to attack in a much more aggressive and holistic way, bringing them solutions that will cause them to say, yes, I want to go from having analog lighting to digital lighting; yes, I want to go from having an analog HVAC building management system to a digital building management system.
Our view is that the installed base, and I've given these statistics before, DOE estimates that there's 100 billion square feet of building space in the US.
A few years ago, our guesstimate was that it was about $3 a square foot to convert; $2.50 a square foot for fixtures, another $0.50 a square foot for controls.
We believe today that with our solution sets, the unified nLight ECLYPSE system, for example, the ability to enable Internet of Things to collect data off of this to provide many more features and benefits of data and what it can do in the space to help a building owner optimize what they are doing is a unique and compelling value proposition.
So the conversion of that installed base and the value of that installed base we think is much higher than what we had originally estimated, 2 or 3 times higher.
And then you put in that outdoor, which is another third the size of that, it's a huge marketplace.
DOE also estimates that less than 15% of the outdoor market has been converted to date; less than 5% of the indoor market has converted to date.
We believe that to be true.
Just look in all offices, drive down the street and you will see the tremendous amount of opportunity.
So what Acuity is doing and what investments that we have made in ramping up not only our headcount, but also the acquisitions that we've made, very strategic in nature, they give us capability to go after that installed base in a very aggressive way.
It's equally applicable to new construction, as well as planned renovation, but it's the unplanned renovation market that is huge; $800 billion, more than that.
So that's what we are targeting as a growth opportunity.
We continue to do well in new construction and planned renovation.
We see opportunities for continued growth there.
We think that we are taking share in that space, but where we think we can really turbocharge our business is to get after the unplanned renovation, and that's what gives us enthusiasm for outsized growth relative to the growth rates of the markets that we serve, as well as being less dependent upon new construction by itself.
Brian Lee - Analyst
All right.
Thanks.
That insight is super helpful.
Maybe just a quick follow-up on mix.
LEDs, you mentioned, is now approximately two-thirds of sales.
I think you have said in the past it's in theory probably not likely that LED becomes the entire business mix.
There's always a place for some amount of traditional lighting technologies.
What do you think is the upper limit on LED mix for you because it does seem like you've grown a lot faster in that segment than expected.
And so just wondering how close you might be getting to what you might consider an upper limit as you see it?
Thank you.
Vern Nagel - Chairman, President & CEO
Sure, sure.
So LEDs today represent almost two-thirds of our total revenues, but I just want to emphasize that Acuity has revenues other than fixture products.
Obviously, Distech is a simple example, but we also sell emergency lighting; we sell poles for outdoor lighting.
So when we think about where our mix actually is for our lighting business -- and we sell control systems too -- it is a much higher percentage than what it means to the overall sales.
So, ultimately, I see Acuity sales continuing to grow in multiple areas, including selling more luminaires.
But I think LED as a percentage, I don't know what the exact number will be, but it will hit a fixed percentage because we will have been converted virtually all to LED within our luminaire business.
I still think that that is a few years away, but I believe it will happen, particularly as LEDs just become more efficacious and they are doing that.
So I think that for our business, I don't know what the exact percentage will be because we sell other things and we will want to sell those other things.
Those other items will continue to grow.
Our building management systems, which tie now that we have nLight ECLYPSE in a unified way with HVAC and other lighting and so on and so forth, we expect that to grow fairly significantly.
So it will continue as a percentage of the total and make LEDs -- it will hold their percentage to our total, and there will be other technologies that will come out there that won't be directly LED that we will also continue to sell and they will be a small portion of our business as well.
