Thank you, Patrick, and good morning. The fourth quarter provided a solid ending to an outstanding year for Franklin Electric. During the quarter our earnings per share increased by 47% and by 35% after adjusting prior year's EPS for some unusual items.
Our fueling team led the way in terms of earnings improvement during the fourth quarter. Fueling sales represented about 23% of our total company sales and increased by 11%. And adjusted fueling operating income grew by 80%.
Our fueling team has done a masterful job integrating the PetroTechnik acquisition. When we acquired PetroTechnik, their operating income margin was about 1/2 the margin level in our existing fueling business. As a result, when we consolidated PetroTechnik, our overall fueling operating income margin fell from its traditional level of about 19% to about 14%. Since then our margins have steadily recovered as the fueling team has achieved their synergy targets.
During the fourth quarter 2011, adjusted fueling margins were 21%, about 800 basis points higher than the prior year and better than our typical pre-acquisition level. In addition, sales of our fuel pumping systems and fuel management system product lines were particularly strong during the quarter.
During the fourth quarter, our water system sales increased by 6%, and our operating income grew by 4.5%. Our fourth quarter Water Systems business was characterized by strong results in the Americas, which more than offset weaker results in Europe, the Middle East and North Africa. During the fourth quarter, our Water Systems sales in North and South America represented about 50% of our consolidated sales and grew organically by 9%.
Throughout 2011, our year-over-year sales of pumping systems for irrigation and industrial applications grew by about 25% in North and South America. And they continue to increasing at this pace in the fourth quarter. We believe that our irrigation and industrial sales growth can be attributed to a combination of favorable weather conditions in North America, strong crop prices and market share gains.
In the fourth quarter, we also achieved double-digit sales growth for residential and light commercial groundwater and wastewater pumping systems in the Americas. Primarily, due to strong replacement demand for these products in the U.S. and Canada.
Product margins in the Americas grew in spite of significant increases in raw material costs experienced throughout 2011. As our sales have continued to grow, our Americas Water Systems management team has done a good job of achieving operating leverage on these sales by driving down their converting cost from the factory floor and holding the line on fixed spending increases.
Our water sales in EMENA, which is Europe, the Middle East and North Africa, represented about 14% of our consolidated sales and increased by 13% during the quarter. However, our EMENA sales declined by 6% when you remove the impact of the Impo acquisition and foreign exchange fluctuations.
Product margins in EMENA declined during the quarter for 2 principal reasons: first, we experienced more rapid raw material inflation in our European factories than in our North American plants. This is partially explained as raw material inflation in North America was offset by hedging certain raw materials with forward purchase strategies that we have only recently been able to implement with our suppliers in Europe. In addition, we have favorable fixed price contracts with raw material suppliers in Europe, which expired midyear. And when these contracts expired, several of our European suppliers implemented catch-up price increases. As a result, our fourth quarter raw material costs as a percentage of sales in Europe increased by 410 basis points compared to the fourth quarter 2010.
Second, our sales growth in EMENA was curtailed by weak economic conditions in Europe and political turmoil in portions of the Middle East and North Africa. So we were unable to generate operating leverage on revenue to offset the lower contribution margin caused by the higher raw material costs. We are increasing prices in EMENA during the first quarter. We believe this price action combined with easier year-over-year raw material cost comparisons should enable us to close the margin gap in EMENA during the second quarter of this year.
Overall, 2011 was an outstanding year of accomplishment for Franklin people worldwide. Financially, we achieved record sales and earnings. Our consolidated sales increased by 15%, our adjusted EPS increased by 42%, our year-over-year margins improved each quarter. We continue to invest in our future by increasing our RD&E spending by 23% during the year. Our balance sheet remains strong, and we were able to increase our dividend payment for the 18th consecutive year.
While these financial achievements are satisfying, we were particularly pleased to have made significant progress on several of our key strategic goals during 2011. We continue to increase our sales base in high-growth developing regions. Our developing regions sales growth -- sales grew by 18% in 2011 and now represents 36% of our consolidated sales. During the year, we completed the Impo acquisition, which gives us the leading position in the large and growing Turkish market and a low-cost base for growing throughout the region. We furthered our quest to continue improving our quality and cost position as we consolidated more of our production into our world class Linares, Mexico production complex, and we laid the groundwork for the construction of a new manufacturing facility in Brazil.
We continued to gain share in the North American water systems pump market. We've only been in the North American groundwater pump market for 6 years, and we've already achieved the leading position. But we still have great headroom for growth as we convert more and more contractors to installing the Franklin brand as we expand our product line.
Finally, we furthered our strategy of introducing new products that provide our customers with a prepackaged system solution. From our customer's perspective, these prepackaged systems can reduce costs, simplify installation and offer a better warranty. From our perspective, these systems can feature more proprietary Franklin technology and significantly increase our revenue per installation. We initiated beta testing on 2 new package systems product lines in 2011: a system to dewater oil and gas wells and a solar-powered water well system. We plan to launch these products commercially later this year.
While 2011 was a great year, it is behind us, and we are fully engaged to pursuing the opportunities and challenges that are confronting us in 2012. As we looked to the first quarter, we're expecting our global water system sales to increase by 6% to 8%, despite our assumption that foreign exchange effects will reduce our global water sales by 2% to 4%. We believe that our first quarter water systems sales growth will be led by increases in the U.S. and Canada and the Asia-Pacific regions. We're currently implementing price increases across most of our global water systems product line. And while these increases will not be fully effective until the beginning of the second quarter, we are anticipating that water operating income will increase by 11% to 14% compared to the first quarter of 2011.
The first quarter is seasonally the slowest for our global fueling business, and sales levels are difficult to predict because they depend upon whether our distributors start stocking up for the summer construction season in March or during the second quarter. At this point, we believe our first quarter fueling sales will grow by 3% to 6%, and we believe that fueling operating income will grow at a similar pace. We expect foreign exchange translation impacts will reduce fueling sales and operating income growth by about 2%. We're also increasing prices across most of our global fueling product lines during the first quarter.
Overall, we're expecting our consolidated earnings per share to increase by 10% to 13% compared to the first quarter 2011.
Now, I'll turn the call over to John Haines, our CFO, who'll provide some additional information regarding our financial performance.
