Analyst · CJS Securities
Thank you, Jeff, and thank you, all, for joining us on the call. I just want to mention that Leigh Abrams, the Chairman of our Board, is also here with us on the call. Before discussing Drew's results, I would like to take this opportunity to congratulate Jason Lippert and Scott Mereness on assuming new leadership positions at Drew this coming May. Most of you know by now that I'll be retiring in May and that Jason will become Drew's CEO and Scott will become Drew's President and COO. We're also very pleased that Joe Giordano will remain as Drew's CFO. Joe will be relocating to Jason's and Scott's neck of the woods in Elkhart County, Indiana, which as you know, is center of the RV world.
I think a lot of you have already had the opportunity to meet and to talk with Jason, Scott and Joe, and you know that they are an exceptionally talented and experienced team. They have the drive, the energy and the strategic insight to take Drew to new heights, and each has been essential to Drew's past success and they are key to our future. As importantly, they had developed an extraordinarily strong and broad team of executives and managers who are highly capable of contributing to Drew's success. I know that it sounds a little bit like a speech because it is part of my prepared remarks, but it's also very true and I think everyone here at Drew, our Board, our management team are all very comfortable with the succession plan we've been through that our Board implemented over the last couple of years, and we're all looking forward to continue to success -- continued success for Drew. In the meantime, however, you're stuck with my somewhat notoriously long-winded speeches for just a little while longer.
We're quite pleased with both the continuing strength in the RV industry in general and the strong demand for our products in particular. Drew's sales of components for new towable RVs increased 29% this quarter. For more than a decade, we've consistently outpaced the RV industry growth, and we've done that by providing outstanding products and outstanding service to the leading producers of RVs across the country. This growth has enabled us to achieve a record $900 million in sales in 2012. We look forward to achieving new milestones in sales and profits in the years to come.
RV industry fundamentals also appear to be solid. While recent industry production levels have exceeded retail sales, that's to be expected I think both seasonally and in the recovery mode. Most industry analysts report that dealer inventories are now in line with retail demand. Further, based on data regarding the age of RVs on the road, there has been some conjecture that we may be in the early stages of an RV replacement cycle that could boost retail sales in coming years. Of course, improving our bottom line is the top priority of our entire management team.
Our production efficiencies at several key facilities did improve in the fourth quarter. However, the impact of this improvement was messed by continued cost for facility consolidations and lean manufacturing initiatives, as well as other transitory cost increases, which we expect will decline over the next 2 quarters. We're also in a position to achieve significant improvements in the bottom line results of several of our newer product lines as we progressed through 2013, including awnings and extrusions. We understand, however, that actual results speak much louder than expectations. And that our actual operating profit margin in 2012 did not meet expectations. However, 2012 was a year of significant accomplishments.
In 2012, we achieved a 24% increase in net income, and we gained significant momentum in our efforts to expand outside our core markets. Sales to adjacent markets were up 68% compared to 2011. And together with our aftermarket products, sales to new markets exceeded $130 million last year, about 15% of consolidated sales.
Even within the RV market, we continue to develop new opportunities for growth through new products, such as awnings, and a 91% increase in sales of motorhome components to our OEM customers. So encouraging RV industry fundamentals, along with our solid growth in both the core markets and in the new adjacent markets, is an exciting combination for us.
Further in 2012, we returned $45 million to our stockholders through the $2 per share special dividend in December. And this followed a special dividend of $33 million or $1.50 per share just 2 years earlier. These dividends, paid during a period when we also made significant investments in our future through acquisitions, capacity expansion and productivity initiatives, exemplify our commitment to optimizing long-term stockholder returns.
We are committed to continuing our track record of generating favorable returns on assets and equity. In that regard, Drew's return on assets in 2012 increased to 9.6%. Our return on equity reached 12.7%, well above the last reported median ROE of 8.9% for the S&P small-cap 600. Drew's executive compensation programs are designed to reward us for achieving high returns on investments. This incentivizes our executives to undertake external investments or internal growth projects only if we can expect high returns. In 2013, we are expanding these performance-based compensation programs to include even more key executives.
So for many companies, this long string of accomplishments I just cited will be cause for a celebration of 2012 as a banner year. While we are pleased with our success, we are not nearly satisfied and we'll continue to devote our efforts to profit improvement and return on investment. We are quite comfortable that we have numerous opportunities to improve during 2013, including those we created through long-term investments in the past few years, those resulting from RV industry growth, and those we are continuing to identify. And we expect to handle those opportunities without disrupting our emphasis on production efficiencies. We look forward to reporting improved bottom line results in 2013, particularly in the second half of the year.
Once again, I really would like to express my personal confidence in Jason, Scott, Joe and the outstanding team they build. Having been a part of the Drew organization for 32 years, I take pride in knowing that Drew will continue to be in their very capable hands. And now I'll ask Joe to review our results in more detail.
