in late 2008 , the business environment became challenging due to adverse global economic conditions . these conditions slowed global economic growth and resulted in recessions in many locations , including the u.s. , europe and certain countries in asia . these conditions materially and adversely impacted our financial condition and results of operations for 2009. global economic conditions improved throughout 2010 , contributing to a substantial increase in our business volume . as a result of this increase in business volume and the realization of benefits from our previous restructuring actions , our net sales and gross profit increased significantly during 2010 and we had our first profitable year since 2001. in 2011 , our net sales increased 4.5 % and we achieved another profitable year . however , the economic environment continues to be challenging due to high levels of unemployment , concerns about debt levels and possible recessions in certain countries , and other factors . recently , these conditions have resulted in reduced demand for many of our customers ' products , causing these customers to reduce or reschedule their orders with us . additionally , we may experience supply chain constraints in the near term due to the recent floods in thailand . because of these factors , we are cautious as we enter 2012. we have experienced fluctuations in our results of operations in the past and may continue to experience such fluctuations in the future . all references in this section to our operating results pertain only to our continuing operations and all references to years refer to our fiscal years ending on the last saturday of each year closest to september 30th . fiscal 2011 and 2010 are each 36 52 weeks and 2009 was 53 weeks , with the additional week included in the fourth quarter . the additional week in 2009 did not significantly affect our results of operations . a relatively small number of customers have historically generated a significant portion of our net sales . sales to our ten largest customers represented 49.9 % of our net sales for 2011 and 2010 and 48.0 % of our net sales for 2009 . for 2011 and 2010 , one customer represented more than 10 % of our net sales in each period . for 2009 , no customer represented 10 % or more of our net sales . we typically generate a significant portion of our net sales from international operations . net sales generated from non-u.s. operations were 81.8 % , 79.0 % , and 76.9 % of our net sales for 2011 , 2010 and 2009 , respectively . the concentration of international operations has resulted primarily from a desire on the part of many of our customers to move production to lower cost locations in regions such as asia , latin america and eastern europe . we expect this trend to continue . historically , we have had substantial recurring sales from existing customers . we typically enter into supply agreements with our major oem customers . these agreements generally have terms ranging from three to five years and cover the manufacture of a range of products . under these agreements , a customer typically agrees to purchase its requirements for specific products in particular geographic areas from us . these agreements generally do not obligate the customer to purchase minimum quantities of products . in some circumstances , our supply agreements with customers provide for cost reduction objectives during the term of the agreement . 37 critical accounting policies and estimates management 's discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements which have been prepared in accordance with accounting principles generally accepted in the united states . we review the accounting policies used in reporting our financial results on a regular basis . the preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets , liabilities , net sales and expenses and related disclosure of contingent liabilities . on an ongoing basis , we evaluate the process used to develop estimates for certain reserves and contingent liabilities , including those related to product returns , accounts receivable , inventories , income taxes , warranty obligations , environmental matters , restructuring , and contingencies and litigation . we base our estimates on historical experience and on various other assumptions that are believed to be reasonable for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources . our actual results may differ materially from these estimates . we believe the following critical accounting policies reflect the more significant judgments and estimates used by us in preparing our consolidated financial statements : accounts receivable and other related allowances— we estimate uncollectible accounts , product returns and other adjustments related to current period net sales to establish related allowances . in making these estimates , we analyze the creditworthiness of our customers , past experience , changes in customer demand , and the overall economic climate in the industries we serve . if actual uncollectible accounts , product returns or other adjustments differ significantly from our estimates , the amount of sales or operating expenses we report would be affected . one of our most significant credit risks is the ultimate realization of our accounts receivable . this risk is mitigated by ( i ) a significant portion of sales to well-established companies , ( ii ) ongoing credit evaluation of our customers , ( iii ) frequent contact with our customers , especially our most significant customers , which enables us to monitor changes in their business operations and to respond accordingly and ( iv ) obtaining , in certain cases , a guaranty

currency fluctuations through the use of foreign currency hedging instruments ; however , hedges are established based on forecasts of foreign currency transactions . to the extent actual amounts

unamortized debt issuance costs of $ 0.8 million that were expensed upon repurchase of the debt and a $ 6.1 million charge associated with de-designation of a related interest rate swap . provision
