with respect to our expectations for 2013 , we are targeting full year organic growth in the range of 3 % to 5 % ( inclusive of a negligible foreign exchange impact ) and acquisition related growth of approximately 4 % for acquisitions completed in 2012. based on these revenue assumptions , our profitability expectations and anticipated additional share buy-backs , our diluted earnings per share from continuing operations for 2013 is estimated to be in the range of $ 5.05 to $ 5.35 , and we expect our earnings to follow a traditional seasonal pattern of being higher in the second and third quarters . if global or domestic economic conditions accelerate or deteriorate , our operating results for 2013 could be materially different than currently projected . 25 consolidated results of operations as discussed in note 3 to the consolidated financial statements in item 8 of this form 10-k , in the fourth quarter of 2012 , we reclassified certain businesses in the printing & identification segment to discontinued operations based on our decision to divest these businesses . the results of operations of these businesses have been removed from the results of continuing operations and are presented within results of discontinued operations for all periods presented . replace_table_token_6_th revenue our 2012 consolidated revenue increased 10 % to $ 8.1 billion , reflecting organic growth of 5 % , growth from acquisitions of 6 % and an unfavorable impact from currency translation of 1 % . all four of our segments generated 2012 organic revenue growth , with the majority attributed to volume increases driven by strength in the energy , handset , refrigeration and food equipment , and many of the other industrial markets served by our engineered systems segment . approximately 3 % of our growth was generated by new products , particularly in our communication technologies segment , and geographic market expansion in our energy segment . pricing had a negligible impact to 2012 revenue , as price increases implemented to offset higher commodity costs , were partly offset by lower strategic pricing initiatives . revenues generated outside of the u.s. increased by 9 % compared with 2011 , with growth in canada and asia offsetting weakness in europe . over 80 % of the 2012 revenue growth from acquisitions was generated by sound solutions , maag pump systems , and production control services , three of our more significant recent acquisitions made in the second half of 2011 and first half of 2012. our 2011 consolidated revenue increased $ 1.3 billion or 21 % compared with 2010 , reflecting organic growth of 12 % , growth from acquisitions of 7 % and a favorable impact from currency translation of 2 % . the majority of our 2011 organic growth was attributed to increased volumes across all four segments driven by strength in the energy and consumer handset markets and solid growth in fluid solutions , refrigeration equipment and many of the industrial markets served by our engineered systems segment . additionally , approximately 2 % of our growth was generated by new products , particularly in our communication technologies and printing & identification segments . pricing added about 1 % to revenue principally driven by strategic pricing initiatives and price increases implemented to offset higher commodity costs . revenues generated outside of the u.s. increased by 25 % compared with 2010 , with revenue generated in emerging economies of china and latin america increasing 56 % . 26 over 70 % of the 2011 revenue growth from acquisitions was generated by harbison-fischer and sound solutions , two large acquisitions that we made in 2011 to expand our operations serving the artificial lift and handset markets , respectively . gross profit our gross profit increased $ 262.3 million or 9 % in 2012 compared with 2011 , reflecting the benefit of increased sales volumes , favorable net material costs , and benefits from productivity initiatives . gross profit margin as a percentage of revenue contracted 30 basis points in 2012 to 38.3 % from 38.6 % in 2011 , with the reduction in large part due to the integration of sound solutions , which generated lower than anticipated revenue in 2012 , more than offsetting the operating leverage achieved by our other businesses . our gross profit increased $ 422.2 million or 17 % in 2011 compared with 2010 , reflecting the benefit of increased sales volumes . however , gross profit margin as a percentage of revenue contracted 110 basis points in 2011 to 38.6 % from 39.7 % in 2010 due principally to the impact of product and customer mix , which more than offset operating leverage , as well as the impact of higher depreciation from recent acquisitions . story_separator_special_tag although there was an incremental decrease in revenue due to strategic pricing initiatives for our communication and telecommunication products corresponding to normal product life cycle maturities , this decrease was more than offset by revenue growth from market share gains , new product introductions and product mix . our revenue in the consumer electronics market ( representing 40 % of 2011 segment revenue ) increased $ 91.8 million or 35 % , excluding sound solutions . our mems microphones and sisonic technologies were well positioned to capitalize on this market 's growth as we have continued to invest in capacity to meet the growing market demands . our medical technology revenue ( 17 % of segment revenue ) declined by $ 6.6 million or 3 % principally due to softer hearing aid demand in the first half of 2011 and overall softer medical equipment demand . 31 our aerospace/defense revenue ( 29 % of 2011 segment revenue ) increased $ 25.3 million or 7 % . we experienced solid demand in the commercial aerospace market due to increased build rates of commercial aircraft by leading aircraft manufactures and increased demand for our aftermarket products globally . this increase was partially offset by revenue derived from our defense market mainly due to timing and funding of certain programs in which we participate . our telecom/other revenue ( 14 % of 2011 segment revenue ) decreased $ 16.6 million or 8 % due to weakened demand in the global telecom markets , driven in part by deferred industry investment due to service provider consolidation . communication technologies 2011 earnings increased 10 % compared with 2010 , but operating margin declined 250 basis points . the margin decline mainly resulted from higher acquisition related costs including incremental depreciation and amortization , higher raw material costs , and lower margins from the integration of the sound solutions acquisition . excluding the impact of sound solutions , earnings would have increased by $ 36.6 million , or 18 % , and operating margin would have increased by 160 basis points as compared with 2010. energy our energy segment serves the oil , gas , and power generation industries with products that promote efficient and cost-effective drilling , extraction , storage , and movement of oil and gas products , or constitute critical components for power generation equipment . the energy segment operates through the following business lines : drilling , which comprises products supporting the cost-effective drilling of oil and gas wells ; production , which comprises products and components facilitating the extraction and movement of fuel from the ground ; and downstream , which comprises systems and products that support the efficient , safe , and environmentally-sensitive handling of fuel , hazardous liquids , and dry-bulk commodities . replace_table_token_8_th 32 2012 versus 2011 our 2012 energy segment revenue increased $ 271.9 million or 14 % compared to 2011. the increase was driven by organic revenue growth of 9 % , growth from the acquisitions of production control services ( in april 2012 ) and oil lift ( in september 2011 ) totaling 5 % , and a negligible impact from foreign currency translation . pricing actions , mainly in response to increased raw material costs , represented approximately 2 % of the revenue increase . drilling revenue ( representing 19 % of 2012 segment revenue ) increased by $ 8.3 million or 2 % due to an essentially flat level of drilling activity compared to 2011 , which moderated demand for the segment 's drilling products . production revenue ( 54 % of 2012 segment revenue ) increased by $ 213.0 million 22 % , with 12 % due to organic growth and 10 % from acquisitions . organic growth was driven by an increased number of active u.s. oil wells and wells with natural gas liquids driving demand for artificial lift products , higher international sales , and increased demand for compressor related products and winch products serving the infrastructure and recovery markets . our revenues in the drilling sector , and to a smaller extent in the production sector , are impacted by changes in the number of active north american drilling rigs . in 2012 , the average north american drilling rig count declined 1 % compared to the prior year . we expect the north american rig count growth to turn positive in the second half of 2013. downstream revenue ( 27 % of 2012 segment revenue ) increased by $ 50.5 million or 10 % , reflecting increased demand for loading equipment for the rail , cargo tank and chemical/industrial markets , bearing products serving energy markets , and fuel delivery systems . energy earnings in 2012 increased $ 88.0 million or 20 % primarily resulting from higher volume in the production and downstream sectors . operating margin increased 110 basis points compared to the prior year due to improved operating leverage associated with higher volumes , strategic pricing , and productivity gains , which more than offset the impact of unfavorable product mix and higher acquisition-related depreciation and amortization . bookings for the year ended december 31 , 2012 and backlog at december 31 , 2012 increased 11 % and 4 % , respectively , compared to the prior year periods . we expect market conditions in 2013 to moderate compared to 2012 , with continued geographic expansion and further penetration of new and acquired products and technologies are also expected to contribute to our growth in 2013 . 2011 versus 2010 our energy segment posted record organic revenue , earnings , and bookings in 2011. revenue and earnings were up 46 % and 43 % , respectively , due to continued strength in the drilling , production , and downstream energy markets served by the segment . recent acquisitions generated revenue growth of 19 % and contributed to the segment 's record results . sales outside of north america grew 35 % driven by significantly higher sales
