Thank you very much, Erica. Good morning, everyone, and welcome to Badger Meter's Third Quarter Conference Call. I want to thank all of you for joining us. As usual, I will begin by stating that we will make a number of forward-looking statements on our call today. Certain statements contained in this presentation, as well as other information provided from time to time by the company or its employees, may contain forward-looking statements that involve risks and uncertainties that could cause actual results to differ materially from those in these forward-looking statements. Please see yesterday's earnings release for a list of words or expressions that identifies such statements and the associated risk factors.
Let me reiterate some of our guidelines. For competitive reasons, we do not comment on specific individual product line profitability other than in general terms, nor do we disclose components of cost of sales, for example, copper. More importantly, we continue our practice of not providing specific guidance on future earnings. We believe specific guidance does not serve the long-term interest of our shareholders.
Now on to the third quarter results. Yesterday afternoon after the market closed, we released our third quarter 2012 results. Net sales for the 3 months ended September 30, 2012, increased $17.4 million or 25% to $87.1 million compared to $69.7 million in the third quarter of last year. The increase was due in part to the inclusion of Racine Federated's results in the third quarter.
Just to refresh your memory, we acquired Racine Federated on January 31 of this year. Racine Federated sales in this year's third quarter were $11.8 million. In addition, we saw increases in our municipal water business.
Let's review third quarter sales for each of our product groups. Municipal water sales increased $5.7 million or 10.8% from $53.0 million in the third quarter of 2011 to $58.7 million in the third quarter of 2012. These sales represented 67.4% of sales for this quarter. The increase was due to higher sales of residential meters sold with technology, as well as higher commercial meter sales.
Sales of meters in related technology increased 11.1% on higher volumes. Manually read residential meter sales decreased slightly due to lower volumes sold. Commercial meter sales increased 10.8% in this period over the same period last year due to higher volumes of products sold. Sales of our industrial products represented 23.5% of sales for the third quarter. These sales increased $10.2 million or 98.1% to $20.5 million from $10.4 million last year. As we have discussed, most of Racine Federated sales are included in this group. Their sales in this product grouping were $9.2 million for the quarter. Remainder of the increase was due to higher sales in most of the remaining industrial product lines.
Specialty application products represented 9.1% of sales for the most recent quarter. These sales increased $1.6 million in the third quarter or 25.4% to $7.9 million from $6.3 million during the same period in 2011. Included in this product grouping was $2.6 million of sales from Racine Federated. The increase from these sales was more than offset by a sales reduction of radios sold into the natural gas market. As we've been explaining all year, last year's sales included significant amounts of radios sold to one particular natural gas customer that are not recurring this year. We also saw slightly lower sales of valves.
Gross margin as a percent of sales was 39.4% in the third quarter compared to 32.7% from the third quarter of last year. The net increase was due in part to the addition of the Racine Federated product line, whose products have higher margins and lower costs for our municipal water meter castings. Higher volumes through our facilities and a favorable exchange rate also contributed to the higher margin percentage.
Selling, engineering and administration, or as we refer to them, our SMEGA expenses, for the quarter increased $5.4 million or 36.7% over the same period last year. The increase was primarily due to the acquisition of Racine Federated and the amortization of the intangibles acquired with that acquisition, which were not included in the results last year.
In addition, we took $1 million charge to write down our investment in an emerging technology company. The original investment in this company was $1.5 million. While we still believe the technology is viable, we felt it prudent to reduce the carrying value of the investment.
Interest expense for the quarter was higher than last year. Obviously, we borrowed funds to pay for our acquisition and to finance the stock repurchase program that occurred earlier in the year. Also, last year's interest expense included a onetime credit due to the reversal of some tax items.
The provision for income taxes as a percent of earnings before income taxes for the third quarter was 35.9% compared to 40.8% last year. As I mentioned, last year's tax amount did include benefits that totaled nearly $1.5 million. These were for recognition of previously unrecognized tax benefits for certain deductions taken on prior year tax returns. Last year's provision for taxes without those adjustments would've been 33.1%.
As a result of all of this, net earnings for the third quarter 2012 were $8.9 million or $0.62 per diluted share compared to $6.9 million or $0.46 per diluted share for the same period last year. You should also note that the per share amounts are affected by the impact of our stock repurchase program. Without the stock repurchase program, net earnings per share would've been approximately $0.035 less than reported in our news release.
There have been no significant changes in our balance sheet since our last conference call. Our debt to total capitalization ratio at September 30 was just under 30%, and we continue to generate cash. With that, I'll now turn the call over to Rich Meeusen, Badger Meter's Chairman, President and CEO, for his comments. Rich?
