Thanks, Henning, and good morning. Now let's turn to Slide #6, entitled Year-Over-Year Performance. The P&L information on this slide and subsequent slides represent adjusted measures for continuing operations, and is reconciled to U.S. GAAP results and supplemental schedules of the earnings press release. On January 15, we issued a press release announcing preliminary guidance on our fourth quarter 2012 and full year 2012 results. In it, we disclosed a range for adjusted EPS for Q4 and the full year 2012, as well as adjusted EBITDA. These ranges were not affected by a subsequent impairment charge, and our final adjusted EPS for Q4 and for the full year 2012 being reported today are at the top end of the ranges of adjusted results disclosed in the January 15 press release. Subsequent to issuing a press release, as we were completing our audited results, we identified one change affecting our preliminary guidance, a $4.6 million impairment of purchased intangibles. The effect of this impairment was to lower our U.S. GAAP EPS by $0.15 per share compared to the range disclosed in the January 15 press release.
Now I'll go down to Slide #6, and on Slide #6, I'll go down the fourth quarter columns. Revenues were down slightly, the net result of 3% lower revenue to industrial markets and residential markets, while revenues rose 1% for public infrastructure projects and 1% from the late fourth quarter acquisitions. Adjusted operating income grew significantly for the 3-month period, rising to nearly $7 million from a loss of $4 million in Q4 2011, reflecting our improved gross profit and lower SG&A expenses.
Adjusted operating margin was up a comparable degree to 4% for Q4 2012 compared to a negative 2.5% for Q4 2011. Although not shown on Slide 7, the fourth quarter's adjusted gross margin was 19%, an increase of 240 basis points from the fourth quarter of 2011. The increase in the adjusted gross margin was primarily due to an improved material margin and operating efficiencies across all our major businesses. We reduced SG&A expenses, as a percent of revenue in Q4 of 2012, by 400 basis points, as we redesigned our performance share equity award for 2012 to achieve less expense volatility in any quarter. We're translating these factors into their effect on adjusted EPS and bridging from last year's Q4 2011 adjusted loss of $0.17 a share to this year's $0.05 a share, here are the key improvements: a $0.01 improvement from lower interest expense; $0.04 from improved efficiencies across all businesses, including our West Coast residential business; $0.05 improvement on the mix of products sold; and finally, $0.12 of earnings increase came from the redesign equity award for 2012.
Now going down the full year columns on Slide 6, revenues grew 3%, a net result of a 4 percentage point increase due to acquisitions, and for businesses we operated in both 12-month periods, they experienced a slight decrease in pricing with 1 percentage point of revenue. While total volume remained relatively unchanged, we did have volume increases in 2012 with products sold at public infrastructure and multifamily markets, and were met by small decreases in volume and repair -- residential repair and remodeling in industrial markets.
Adjusted operating income increased 10% to $49.6 million for the full year, and that was the net result of the cost -- higher cost in consolidating our West Coast business, being more than offset by profit increases from acquisitions plus our other operations' improved efficiencies, including realized cost savings. Translating these factors into their effect on adjusted EPS for the 12 months and bridging from last year's $0.50 to this year's $0.65 a share, the key improvements were a net $0.03 increase from improved efficiencies and cost reductions, despite the much higher cost of the West Coast reorganization; a $0.05 per share improvement on lower SG&A expenses in 2012, led by lower variable and equity comp costs in 2012; $0.02 improvement from lower interest expense; and finally, a $0.05 improvement came from an effective tax rate that was nearly 5 percentage points lower in 2012.
Now turning to Slide #7, titled, Net Income and EPS. My remarks on this page concern interest expense and income taxes. Regarding income -- interest expense, it was lower in both time periods of 2012 compared to their prior year periods for 2 reasons: first, in 2011, we borrowed funds under our revolving credit facility to help finance 2 acquisitions and during 2012, we had no amounts outstanding on our revolver; and secondly, 2011 benefited from some interest income earned on a note receivable related to a 2008 divestiture, and that note was fully paid off in late 2011.
Regarding income taxes, we recognized lower effective tax rates in the 2012 time periods. The adjusted Q4 2012 tax rate was lower by 640 bps, and the adjusted full year tax rate was lower by 460 bps. The rate reductions were led by discrete benefits in 2012, including the reversal of an uncertain tax position in Q3 2012 after the completion of a tax audit, plus lower nondeductible expenses in 2012.
Now turning to Slide #8, titled, Low Leverage and Strong Liquidity. The upper left bar chart shows the gross debt position of the company, unchanged for the last 3 year ends. And as the upper right bar chart shows, our profitability increased during that time span. Our gross leverage and our net debt leverage came down substantially. The leverage statistics at the end of 2012 do not include the majority of pro forma EBITDA from the 3 acquisitions closed in late Q4 2012. If we will include the full year EBITDA for those 3 acquisitions on a pro forma basis, our gross leverage at the end of 2012 would have been 2.5x.
The bottom half of Slide 8 shows our liquidity position. Liquidity as of the end of the year continues to be quite adequate even after spending $41 million of cash during the fourth quarter of 2012 for the 3 acquisitions. The takeaways from Slide 8 are the company's financial position is in very solid shape and well able to support the company's growth opportunities going forward.
Now to Slide 9, reporting the results of our successful bond refinancing in Q1 of 2013. We issued press releases in mid-January 2013 and again in mid-February, announcing the steps taken to refinance our 8% bond, and those steps have been fully executed and the refinancing was very successful. The majority was extended to 2021 and the annual coupon decreased by 175 basis points, which will provide a nice improvement to the company's 2013 earnings and cash flows.
Turning to Slide 10, whose heading is, Three Acquisitions in Late Q4 2012. As previously noted, we acquired 3 businesses during the fourth quarter. Each is complementary to existing product lines and sales channels. The smallest acquisition, a line of premium brand, exterior awnings and shade products for the residential market, is a product offering that we had been buying and successfully reselling since early 2012 throughout the Southeast U.S. and through our own dealer-direct sales channel. Its future value is expected to increase based on innovative, new product development capability, and it has several exciting new products to be launched this year. Our other 2 businesses are very complementary to existing Gibraltar product lines, serving nonresidential markets. Both are expected to expand the breadth and depth of our geographic sales penetration in the U.S. And we expect their value to increase and initially, through improved cost efficiencies and lower raw material costs.
Turning to Slide 11, titled, Revenues. This slide will help explain our 2013 revenue expectations. First, we've updated Gibraltar's exposures to end markets served. We have used the actual 2012 net sales for the company and added, on a pro forma basis, the 2012 net sales for the 3 most recent acquisitions and compiled these 3 pie charts. The 3 most recent acquisitions had aggregate revenues in 2012 of $55 million. 20% of that served the residential market. 30% of the $55 million serve public infrastructure, and the balance of 50% was industrial markets. And relative to the center pie chart, the 3 acquisitions increased our overall exposure to debt in the industrial markets.
The right half of the center pie chart shows a 50% exposure to residential and low-rise commercial construction, as many of our products installed in personal residences are also installed in low-rise commercial structures, such as professional buildings and retail centers, and product examples include: interior corner bead, external rain dispersion, phasing [ph] trims, attic and foundation ventilation, as well as multiunit mailboxes. And the 2 pie charts on the left side and on the right side of Slide 11 represent deeper views as to what sub-markets generate demand for our products. In 2013, our predominant end market exposure continues to be residential housing demand, both for repair and remodeling activity, followed by new housing.
Thinking about 2013 revenues, going from the right side of this slide to the left side, we are expecting residential repair and remodeling to yield a 2% to 5% increase over 2012, as explained by Henning, and further, our roofing shingle volume -- I'm sorry, further roofing shingle volume is expected to be equivalent in 2012. And although we do not sell looping shingles, its demand correlates to our roofing and attic ventilation products, which make up a substantial portion of our residential market participation. Concerning residential new construction and the improving underlying demand trends, we expect our residential new construction exposure to yield a 10% to 15% increase in 2013, and this market exposures, we estimate will derive about 10% of our consolidated revenues. This is expected to be a quarterly ramp in orders since our products typically would be shipped 6 to 9 months after a permit is pulled to construct a new residence or multifamily building.
Concerning low-rise commercial construction, both new and repair and remodel, the architectural billing index on nonresidential construction activities increased every month since June of 2012, and in January 2013, reached a reading of 54. We expect our market exposure to rise between 4% and 7% compared to 2012 for this end market exposure. Concerning our exposure to public infrastructure for bridges and elevated highways, backlog is a predictor of near-term revenues. We entered 2013 with a very solid backlog and an amount equivalent to backlog in January 2012. And with the current seasonally high level of quoting activity, we expect our revenues to grow organically this year by about 5%. In 2012, we did benefit from a few selected orders that we shipped on large projects such as the San Francisco-Oakland Bay Bridge and a Shell Oil drilling platform out in the Gulf of Mexico. And concerning industrial demand, the composite of the various sub-markets we serve, we do expect organic volume that's flat to 2012, and its weighed down by uneven recovery in North America, and we expect that Europe's continuing recession, where we derive about 15% of our industrial demand and 7% of our consolidated sales.
The above expectations bring us to a weighted average for 2013 revenue growth of 12% compared to 2012, which is a sum of 5% organic growth and 7% growth from completed acquisitions, and our internal planning does reflect a stronger second half and overall we're confident about the full year.
On Slide 12, guidance. Starting with the first quarter of 2013, we expect the first quarter revenues to rise about 4%, which is a net result of a 7% revenue increase from completed acquisitions, while organic sales will likely be lowered by 3%. Organic revenues face an unfavorable comparison, as Q1 2012 benefited from extremely warm weather in most parts of the country last winter that pulled forward demand, particularly for residential-related products into the first quarter of 2012. Adjusted earnings and profits for the first quarter is expected to be similar to Q1 of 2012. While we gain from increased efficiency from our reorganized West Coast operations and our latest completed acquisitions, those improvements are matched by the effects of lower pricing in certain product categories and lower organic volume for residential products compared to last year. And one last point on our expected Q1 2013 P&L results, the adjusted earnings will exclude $7 million of transaction fees related to redeeming the 8% bonds, where we are writing off the remaining balance of deferred financing cost, plus the call premiums.
Now switching to our guidance on the full year 2013, we expect full year revenue and EPS improvement. We expect organic revenue growth approximating 5 percentage points, plus the 7% on acquisitions. It could be seasonal and should be a likely seasonal variation by quarter, of course, and our internal plan again does reflect a second half weighted recovery. We expect that adjusted gross margin for the full year 2013 to be above 20% based on the revenue assumptions I've outlined, including low volatility of raw material costs and the operational improvement of our West Coast residential business.
Regarding our SG&A expense for the full year 2013, we expect it to be slightly lower than 13% of revenue, while including $7 million of incremental SG&A dollars for the 3 acquisitions made in late Q4 2012. Our other expected financial results for the full year 2013 include: adjusted net interest expense in the range of $15.5 million and adjusted effective income tax rate approximating 37%; CapEx spending ranging between $21 million and $22 million; and free cash flow approximating 4% of revenues. And based on these collective expectations, we expect to report adjusted earnings per share from continuing operations to be much improved versus 2012.
With that, I'll turn the call back over to Brian for his concluding remarks.
