acquisitions completed in 2011 and the acquisitions of technical services for electronics ( tse ) in june 2010 , haydon enterprises in july 2010 and atlas material testing technology llc ( atlas ) in november 2010. the full year impact of the 2011 acquisitions and our operational excellence capabilities should have a positive impact on our 2012 results . net sales for 2011 were $ 2,989.9 million , an increase of $ 518.9 million or 21.0 % when compared with net sales of $ 2,471.0 million in 2010. net sales for eig were $ 1,647.2 million in 2011 , an increase of 24.4 % from net sales of $ 1,324.1

50.2 % of net sales , an increase of $ 289.8 million or 23.9 % when compared with international sales of $ 1,211.3 million or 49.0 % of net sales in 2010. the $ 289.8 million increase in international

$ 774.9 million in 2011 , an increase of $ 210.4 million or 37.3 % compared with $ 564.5 million in 2010. export shipments improved due to increased exports from both the base businesses and the acquisitions noted above . new orders for 2011 were $ 3,072.5 million , an increase of $ 421.2 million or 15.9 % when compared with $ 2,651.3 million in 2010. for 2011 , internal order growth was approximately 8 % , excluding a 1 % favorable effect of foreign currency translation , driven by the differentiated businesses of both eig and emg , with the acquisitions mentioned above accounting

respectively . the warranty periods for products sold vary widely among the company 's operations , but for the most part do not exceed one year . the company calculates its warranty expense provision based on past warranty experience and adjustments are made periodically to reflect actual warranty expenses . if actual future sales returns and allowances and warranty amounts are higher than past

financial obligations to the company . a specific reserve for bad debts is recorded against the amount due from these customers . for all other customers , the company recognizes reserves for bad debts based on the length of time specific receivables are past due based on its historical experience . if the financial condition of the company 's customers were to deteriorate , resulting in their inability to make payments , additional allowances may be required . the allowance for possible losses on receivables was $ 7.8 million and $ 6.0 million at december 31 , 2011 and 2010 , respectively . inventories . the company uses the first-in , first-out ( fifo ) method of accounting , which approximates current replacement cost , for approximately 74 % of its inventories at december 31 , 2011. the last-in , first-out ( lifo ) method of accounting is used to determine cost for the remaining 26 % of its inventory at december 31 , 2011. for inventories where cost is determined by the lifo method , the fifo value would have been $ 25.1 million and $ 23.9 million higher than the lifo value reported in the consolidated balance sheet at december 31 , 2011 and 2010 , respectively . the company provides estimated inventory reserves for slow-moving and obsolete inventory based on current assessments about future demand , market conditions , customers who may be experiencing financial difficulties and related management initiatives . if these factors are less favorable than those projected by management , additional inventory reserves may be required . 30 goodwill and other intangible assets . goodwill and other intangible assets with indefinite lives , primarily trademarks and trade names , are not amortized ; rather , they are tested for impairment at least annually . the impairment test for goodwill requires a two-step process . the first step is to compare the carrying amount of the reporting unit 's net assets to the fair value of the reporting unit . if the fair value exceeds the carrying value , no further evaluation is required and no impairment loss is recognized . if the carrying amount exceeds the fair value , then the second step must be completed , which involves allocating the fair value of the reporting unit to each asset and liability , with the excess being implied goodwill . an impairment loss occurs if the amount of the recorded goodwill exceeds the implied goodwill . the company would be required to record any such impairment losses . the company identifies its reporting units at the component level , which is one level below our operating segments . generally , goodwill arises from acquisitions of specific operating companies and is assigned to the reporting unit in which a particular operating company resides . our reporting units are composed of the business units one level below our operating segment at which discrete financial information is prepared and regularly reviewed by segment management . the company principally relies on a discounted cash flow analysis to determine the fair value of each reporting unit , which considers forecasted cash flows discounted at an appropriate discount rate . the company believes that market participants would use a discounted cash flow analysis to determine the fair value of its reporting units in a sale transaction . the annual goodwill impairment test requires the company to make a number of assumptions and estimates concerning future levels of revenue growth , operating margins , depreciation , amortization and working capital requirements , which are based upon the company 's long-range plan . the company 's long-range plan is updated as part of its annual planning process and is reviewed and approved by management . the discount rate is an estimate of the overall after-tax rate of return required by a market participant whose weighted average cost of capital includes both equity and debt , including a risk premium . while the company uses the best available information to prepare its cash flow and discount rate assumptions , actual future cash flows or market conditions could differ significantly resulting in future impairment charges related to recorded goodwill balances . while there are always changes in assumptions to reflect changing business and market conditions , the company 's overall methodology and the population of assumptions used have remained unchanged . in order to evaluate the sensitivity of the goodwill impairment test to changes in the fair value calculations , the company applied a hypothetical 10 % decrease in fair values of each reporting unit . the results ( expressed as a percentage of carrying value for the respective reporting unit ) showed that , despite the hypothetical 10 % decrease in fair value , the fair values of the company 's reporting units still exceeded their respective carrying values by 66 %
