as of december 31 , 2010 , the liability for uncertain income tax positions was $ 2.7 million .due to the high degree of uncertainty regarding timing of potential future cash flows associated with these liabilities , we are unable to make a reasonably reliable estimate of the amount and period in which these liabilities might be paid .we utilize blanket purchase orders to communicate expected annual requirements to many of our suppliers .requirements under blanket purchase orders generally do not become committed until several weeks prior to the company 2019s scheduled unit production .the purchase obligation amount presented above represents the value of commitments considered firm .results of operations our sales from continuing operations in 2010 were $ 1489.3 million surpassing 2009 sales of $ 1375.0 million by 8.3 percent .the increase in sales was due mostly to significantly higher sales in our water heater operations in china resulting from geographic expansion , market share gains and new product introductions as well as additional sales from our water treatment business acquired in november , 2009 .our sales from continuing operations were $ 1451.3 million in 2008 .the $ 76.3 million decline in sales from 2008 to 2009 was due to lower residential and commercial volume in north america , reflecting softness in the domestic housing market and a slowdown in the commercial water heater business and was partially offset by strong growth in water heater sales in china and improved year over year pricing .on december 13 , 2010 we entered into a definitive agreement to sell our electrical products company to regal beloit corporation for $ 700 million in cash and approximately 2.83 million shares of regal beloit common stock .the transaction , which has been approved by both companies' board of directors , is expected to close in the first half of 2011 .due to the pending sale , our electrical products segment has been accorded discontinued operations treatment in the accompanying financial statements .sales in 2010 , including sales of $ 701.8 million for our electrical products segment , were $ 2191.1 million .our gross profit margin for continuing operations in 2010 was 29.9 percent , compared with 28.7 percent in 2009 and 25.8 percent in 2008 .the improvement in margin from 2009 to 2010 was due to increased volume , cost containment activities and lower warranty costs which more than offset certain inefficiencies resulting from the may flood in our ashland city , tn water heater manufacturing facility .the increase in profit margin from 2008 to 2009 resulted from increased higher margin china water heater volume , aggressive cost reduction programs and lower material costs .selling , general and administrative expense ( sg&a ) was $ 36.9 million higher in 2010 than in 2009 .the increased sg&a , the majority of which was incurred in our china water heater operation , was associated with selling costs to support higher volume and new product lines .additional sg&a associated with our 2009 water treatment acquisition also contributed to the increase .sg&a was $ 8.5 million higher in 2009 than 2008 resulting mostly from an $ 8.2 million increase in our china water heater operation in support of higher volumes. .
