, unless otherwise indicated . an analysis of net sales for each business unit is included in the operations review of segment revenue and profit section below . we reported net sales of $ 1,651 million , an increase of $ 433 million or 36 % . during 2011 and 2010 , 86 % and 83 % , respectively of our net sales were generated from the sale of tio 2 . market conditions in 2011 led to strong global demand for tio 2 products throughout the first three quarters of 2011. although demand softened in the fourth quarter , due to customer destocking and slower economic activity globally , our sales price and sales volumes of tio 2 and mineral products were higher than in 2010. cost of goods sold increased 19 % during 2011 as compared to 2010. the increase to cost of goods sold resulted from higher sales volumes , increases in production costs for raw materials , chemicals , energy , employee related costs and unfavorable foreign currency effects . cost of goods sold in 2011 includes $ 36 million of non-cash fresh-start inventory step-up amortization . gross margin increased 109 % or $ 242 million to $ 439 million in 2011 as compared to 2010. gross margin percentage of net sales

rate changes . selling , general and administrative expenses increased $ 98 million to $ 157 million in 2011 as compared to 2010. the increase was primarily due to the following : amortization of intangible assets subsequent to fresh-start accounting of $ 22 million ; employee variable compensation and benefit costs of approximately $ 50 million , including $ 14 million related to amortization of restricted shares during 2011 compared to $ 1 million during 2010 ; costs associated with the acquisition of the mineral sands business , including banker fees , legal and professional fees and the

under the predecessor 's environmental insurance policy related to its remediation efforts at the henderson , nevada site . during 2010 , we recorded receivables from our insurance carrier related to environmental clean-up obligations at the henderson facility . due to the accounting for the legacy environmental liabilities , the obligation for the clean-up work had been recorded in prior years , but the insurance coverage was confirmed in 2010 and 2011. interest and debt expense decreased $ 17 million , or 34 % during 2011 as compared to 2010. the $ 33 million during 2011 is comprised of $ 29 million of interest expense on the exit financing facility and the wells revolver , $ 4 million of other interest expense and $ 1 million of amortization of deferred debt issuance costs , offset by $
