Thank you, Dan. Good morning, everyone. Rick and I would like to make a few comments, and then we'll be happy to answer questions. First, let me say we are very pleased with our results for the third quarter of 2012. We reported strong top and bottom line growth in spite of continued soft economic conditions. This is the ninth quarter in a row where we achieved unit volume growth in an environment, where spending for new nonresidential construction remained weak. I believe this is, yet again, strong evidence our strategy to diversify the end markets we serve and extend our leadership position in North America is succeeding. These strategies include the continued and aggressive introduction of innovative energy-efficient lighting solutions, expansion in key channels and geographies and improvements in customer service.
Our profitability and cash flow for the quarter were again strong, even while we continue to find areas with significant future growth potential, including the expansion of our solid-state luminaire Lighting Controls portfolio. As you well know, the economy in North America continues to be fragile, as consumer confidence lags and job growth remains anemic. Having said this, we believe the many channels and markets we serve are, for the most part, on the road to recovery.
Also in the quarter, we continue to encounter rising costs, particularly for lamps. Overall, we estimate our pricing initiatives have allowed us to recover most of these higher input costs. I mentioned these macro factors because it provides a backdrop against what you can see the outstanding performance of our company again. I know many of you have already seen our results for the quarter, and Ricky will provide more detail later in the call, but I would like to make a few comments on the key highlights.
Net sales for the quarter were $488 million, an increase of more than 6% compared with the year-ago period. This level of growth is significant, given general economic and industry conditions. Operating profit was $57.3 million or 11.8% sales. We took a special charge in the current quarter for previously announced streamlining actions, which reduced operating profit by $1.9 million. Ricky will talk more about the special charge later in the call.
I find it helpful to add back this special charge to current quarter's result to make them comparable with the prior year. Doing so, one can see adjusted operating profit was over $59 million, up almost 18% from the year-ago period, while adjusted operating profit margins improved 110 basis points to a strong 12.1% of sales. Diluted earnings per share were $0.78. Again, adding back the impact of the special charge, adjusted diluted EPS for the current quarter was $0.82, up 32% from the year-ago period. These results for the quarter were significant improvements over the year-ago period. We believe you will find these results even more impressive upon further analysis.
On a consolidated basis, net sales grew more than 6% compared with a year ago. More than 5 of the 6 points of growth were due to greater product shipments with the balance coming from the benefit of better price and product mix. The impact of acquisitions and foreign currency on net sales were not significant and essentially offset each other.
All of the increase in net sales occurred in North America. Our growth was broad-based with gains occurring in most channels. Growth in our largest channel, commercial and industrial, was due to continued emphasis on selling higher value-add lighting solutions, especially LED-based luminaires, which grew by almost 250% compared with the year-ago period, as well as continued focus on smaller- and medium-sized projects of various types sold through distributor stock and flow. We also continue to enjoy solid growth in other important channels, including home improvement and infrastructure, all of which is very encouraging in spite of the variability in demand within nonresidential construction.
As we have noted before, it is impossible to precisely determine the separate impact that price and product mix changes have in our net sales. Having said that, we estimate the positive impact on sales from price mix was primarily due to the benefits from previously announced price increases to recover rising input cost. We estimate our pricing actions helped offset more than most of the approximately $8 million in higher input cost compared with the prior year. Looking at all this a bit more closely, there are some interesting points to note.
We believe spending in key segments of the U.S. nonresidential construction market was up modestly in the quarter compared with the year ago, as was the lighting market. This is in contrast with our unit volume growth in North America, which was up more than 5%. We believe our channel and product diversification, as well as our strategies to better serve customers with the new, more innovative lighting solutions and the strength of our many sales forces have allowed us to, yet again, outperform the markets we serve. Our solid growth in challenging market is due in large part to our focused strategy to diversify our portfolio to be less reliant on new building construction and more focused on growing portions of the market, including renovation and lighting control solutions that enhance the visual environment while optimizing energy usage.
Before I turn the call over to Ricky, I would like to comment on our profitability and strategic accomplishments in the quarter. Excluding the impact of the special charge, adjusted operating profit margin was a strong 12.1%, up 110 basis points from the year-ago period. In fact, we earned more adjusted operating profit this quarter than any quarter since 2008, and this was our highest operating profit margin in the last 14 quarters. Further, I would like to highlight a couple of key points.
First, as I noted earlier, we believe our price increases covered most of the higher cost for materials and components. However, as you know, this dilutes our margin percentage. Next, selling, distribution and administrative expenses increased only $3.4 million or a little more than 2% on an increase in net sales of more than 6%. The increase in SD&A this quarter was due to the incremental variable cost to support growth in net sales and additional variable compensation marketing expenses.
Productivity improvements helped to offset other increases in SD&A expenses, which were primarily related to activities focused on longer-term growth opportunities, including market diversification, expanding our Lighting Control portfolio and investing in innovation and technology primarily for solid-state luminaires and intelligent lighting solutions. We expect to continue funding these important strategic activities, which are mostly an expense in our P&L today, because they represent huge future growth potential over the next decade. While revenues are ramping up in these areas, they are nowhere near anticipated peak sales. We expect they will pay significant dividends in the future. As a point of reference, SD&A that is not directly variable with sales volume was approximately $89 million this quarter, in line with our expectations noted in our last quarter's earnings call.
On the strategic front, we continued our rapid pace of introduction of new products, significantly expanding our industry-leading portfolio of innovative energy-efficient luminaires and lighting control solutions. The rapid introduction of innovative, more energy-efficient products and services have been key contributors to our improved performance over the last few years. This, contrary to the view of some analysts, has allowed us to extend our market leadership position and is one of the cornerstones of our growth strategy going forward.
As I mentioned earlier, our solid-state lighting portfolio is expanding rapidly as of the sales of these luminaires. Today, LED-based products are nearly 10% of our sales with margins generally in the range of other fixtures with traditional light sources. And we continue to fund the development of other light source technologies, such as organic LEDs, where we continue to expand our award-winning portfolio of these innovative products.
Acuity is a clear leader in digital lighting solutions. It is because we understand the sophisticated needs of our expansive customer base and are able to offer each tailored solutions from our industry-leading portfolio. Customers understand it takes more than just an LED chip, which has quickly become a commodity, for a fluorescent lamp to be a true lighting company like Acuity Brands. At Acuity, we offer customer superior quality lighting and energy-efficient solutions for virtually every indoor and outdoor application regardless of the light source. This is again why we are expanding our leadership position. Our organization has a long distinguished history of leading innovation during years of technology disruption. Today is clearly no different.
Acuity Brands is leading the evolution to intelligent lighting solutions with its broad and deep portfolio of indoor and outdoor solid-state and traditional energy-efficient luminaires and lighting controls. And we are delivering profitable growth and strong returns while making these important investments.
Our formidable strength in innovation was on full display early in the quarter when Acuity won a total of 11 awards at 2 key industry events for its indoor and outdoor LED lighting solutions. These awards included the prestigious Best in Class designation at the Next Generation Luminaires Solid State Lighting Design Competition. No other competitor even came close to this level of success at these events.
Again, we are a lighting company. We are extending our leadership position because customers understand it takes more than flapping a chip on a board and shining in someone's eyes to be a leading lighting company. These accomplishments that diversified strength in our foundation will further serve as a robust platform for our future growth that is less reliant on the new commercial construction cycle.
We have been able to produce these results because of the dedication and resolve of our 6,000 associates and the progress that they have made in 4 key areas of strategic focus: customer service; pricing and margin management; geographical channel and product portfolio expansion, including significant additions to our industry-leading stable of sustainable and energy-efficient lighting solutions; and company-wide productivity.
I will talk more about our future growth strategies and our expectation 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 2012 and beyond. Ricky?
