decreased production volume as final aircraft deliveries were completed during the second quarter of 2012 and $ 50 million from the favorable resolution of a contractual matter during the second quarter of 2012 ; and about $ 270 million for various other programs ( primarily sustainment activities ) due to decreased volume . the decreases were partially offset by higher net sales of about $ 295 million for f-35 production contracts due to increased production volume and risk retirements ; approximately $ 245 million for the c-5 program due to increased aircraft deliveries ( six aircraft delivered in 2013 compared to four in 2012 ) and other modernization activities ; and about $ 70 million for the f-35 development contract due to increased volume . aeronautics 2019 operating profit for 2013 decreased $ 87 million , or 5% ( 5 % ) , compared to 2012 . the decrease was primarily attributable to lower operating profit of about $ 85 million for the f-22 program , which includes approximately $ 50 million from the favorable resolution of a contractual matter in the second quarter of 2012 and about $ 35 million due to decreased risk retirements and production volume ; approximately $ 70 million for the c-130 program due to lower risk retirements and fewer deliveries partially offset by increased sustainment activities ; about $ 65 million for the c-5 program due to the inception-to-date effect of reducing the profit booking rate in the third quarter of 2013 and lower risk retirements ; approximately $ 35 million for the f-16 program due to fewer aircraft deliveries partially offset by increased sustainment activity and aircraft configuration mix . the decreases were partially offset by higher operating profit of approximately $ 180 million for f-35 production contracts due to increased risk retirements and volume . operating profit was comparable for the f-35 development contract and included adjustments of approximately $ 85 million to reflect the inception-to-date impacts of the downward revisions to the profit booking rate in both 2013 and 2012 . adjustments not related to volume , including net profit booking rate adjustments and other matters , were approximately $ 75 million lower for 2013 compared to backlog backlog decreased slightly in 2014 compared to 2013 primarily due to lower orders on f-16 and f-22 programs . backlog decreased in 2013 compared to 2012 mainly due to lower orders on f-16 , c-5 and c-130 programs , partially offset by higher orders on the f-35 program . trends we expect aeronautics 2019 2015 net sales to be comparable or slightly behind 2014 due to a decline in f-16 deliveries as well as a decline in f-35 development activity , partially offset by an increase in production contracts . operating profit is also expected to decrease in the low single digit range , due primarily to contract mix , resulting in a slight decrease in operating margins between years . information systems & global solutions our is&gs business segment provides advanced technology systems and expertise , integrated information technology solutions and management services across a broad spectrum of applications for civil , defense , intelligence and other government customers . is&gs has a portfolio of many smaller contracts as compared to our other business segments . is&gs has been impacted by the continued downturn in certain federal agencies 2019 information technology budgets and increased re-competition on existing contracts coupled with the fragmentation of large contracts into multiple smaller contracts that are awarded primarily on the basis of price . is&gs 2019 operating results included the following ( in millions ) : .

Table:
 | 2014 | 2013 | 2012
net sales | $ 7788 | $ 8367 | $ 8846
operating profit | 699 | 759 | 808
operating margins | 9.0% ( 9.0 % ) | 9.1% ( 9.1 % ) | 9.1% ( 9.1 % )
backlog at year-end | $ 8700 | $ 8300 | $ 8700
2014 compared to 2013 is&gs 2019 net sales decreased $ 579 million , or 7% ( 7 % ) , for 2014 compared to 2013 .
the decrease was primarily attributable to lower net sales of about $ 645 million for 2014 due to the wind-down or completion of certain programs , driven by reductions in direct warfighter support ( including jieddo and ptds ) and defense budgets tied to command and control programs ; and approximately $ 490 million for 2014 due to a decline in volume for various ongoing programs , which reflects lower funding levels and programs impacted by in-theater force reductions .
the decreases were partially offset by higher net sales of about $ 550 million for 2014 due to the start-up of new programs , growth in recently awarded programs and integration of recently acquired companies. .
