Thanks, David. Good morning, everyone. Thanks for joining us on our call this morning. I'll begin, as usual, with some brief comments and then I'll turn the call over to Henning and Ken for a more detailed review of our results. And then following that, I'll close our prepared remarks with comments about our business outlook, before opening the call to any questions that any of you may have.
You can now refer to Slide 3 in our presentation. Gibraltar performed solidly in the first quarter, starting 2012 with double-digit sales growth sequentially as well as compared to a year ago, despite these persistently weak economic conditions especially in the construction markets that we serve.
Our top line growth is the result of high market share in our major product categories, providing new products and expanded programs to our customers and judiciously using our liquidity to acquire product lines that will enhance our customer offerings, expand the markets we serve and, ultimately, help raise the value of Gibraltar.
On February 14, we announced the purchase of Edvan Industries, a grating fabricator serving the oil sands region of Alberta, Canada. While our AMICO business has a strong presence in serving the energy markets in North America, the addition of Edvan helps solidify Gibraltar's exposure to the growing oil and gas market of Western Canada.
As we look forward to the second quarter and beyond, we have a well-positioned portfolio of products serving a diverse set of markets with good, long-term growth prospects. And for additional color on this point, please turn to Slide #4.
Looking back at the past 3 years, through organic growth, acquisitions and divestitures, we've expanded our presence in the nonresidential, industrial and infrastructure end markets to 50% of our current total sales from 30% in 2008.
In the residential part of our business, the portion of sales related to housing starts is now down to approximately 25%, or approximately 12.5% of our overall business, with the other 75%, or 37.5% of our overall business, being driven by home repair and remodeling activity. Despite the very soft market, we continue to take share.
The other 1/2 of our total sales, which come from nonresidential markets, is about evenly split between the building, construction, infrastructure and industrial sectors, with 55% of that being driven by repair, remodeling and replacement applications.
In both the residential and nonresidential markets, this type of activity typically begins picking up well in advance of new construction. We believe that our success in combining nonresidential diversification with a stronger presence in repair, remodeling and replacement in all of our end markets is a key reason that we've been able to deliver organic top line growth during an unprecedented and continuing downturn in the housing sector, and we expect that continuing sales growth will drive further improvements in our profitability.
I'll come back with some additional observations on where the business is heading after Henning and Ken review our first quarter results in greater detail. Henning?
