2011 compared to 2010 is&gs 2019 net sales for 2011 decreased $ 540 million , or 5% ( 5 % ) , compared to 2010 .
the decrease primarily was attributable to lower volume of approximately $ 665 million due to the absence of the dris program that supported the 2010 u.s .
census and a decline in activities on the jtrs program .
this decrease partially was offset by increased net sales on numerous programs .
is&gs 2019 operating profit for 2011 increased $ 60 million , or 7% ( 7 % ) , compared to 2010 .
operating profit increased approximately $ 180 million due to volume and the retirement of risks in 2011 and the absence of reserves recognized in 2010 on numerous programs ( including among others , odin ( about $ 60 million ) and twic and automated flight service station programs ) .
the increases in operating profit partially were offset by the absence of the dris program and a decline in activities on the jtrs program of about $ 120 million .
adjustments not related to volume , including net profit rate adjustments described above , were approximately $ 130 million higher in 2011 compared to 2010 .
backlog backlog decreased in 2012 compared to 2011 primarily due to the substantial completion of various programs in 2011 ( primarily odin , u.k .
census , and jtrs ) .
the decrease in backlog during 2011 compared to 2010 mainly was due to declining activities on the jtrs program and several other smaller programs .
trends we expect is&gs 2019 net sales to decline in 2013 in the mid single digit percentage range as compared to 2012 primarily due to the continued downturn in federal information technology budgets .
operating profit is expected to decline in 2013 in the mid single digit percentage range consistent with the expected decline in net sales , resulting in margins that are comparable with 2012 results .
