the downturn stemmed from a multitude of factors , including adverse credit conditions , slower economic activity , concerns about inflation and deflation , rapid changes in foreign exchange rates , increased energy costs , decreased consumer confidence , reduced corporate profits and capital spending , adverse business conditions and liquidity concerns . although there was an increase in global economic activity in 2010 , economic growth may remain sluggish during 2011 in a few developed countries and in some emerging market countries . the severity or length of time that these adverse economic and financial market conditions may persist , or whether such adverse conditions may return in the u.s. and in other countries , is unknown . during challenging or uncertain economic times , and in tight credit markets , many customers may delay or reduce capital expenditures , which in turn often results in lower demand for our products . sales to customers outside of the u.s. in 2010 , 2009 , and 2008 represented 50 % , 49 % , and 44 % of net revenue , respectively . a significant portion of international sales are made to distributors and system integrators , which are generally responsible for importing the products and providing installation and technical support and service to customers within their territory . we expect international sales to continue to account for a substantial portion of our net revenue for the foreseeable future , and expect that , partially as a result of the acquisitions of scopus and omneon , our international sales may increase . further , we have a number of international customers to whom sales are denominated in u.s. dollars . sales denominated in foreign currencies were approximately 6 % , 7 % and 6 % of net revenue in 2010 , 2009 and 2008 , respectively . the value of the u.s. dollar fluctuates significantly against many foreign currencies , which includes the local currencies of many of our international customers . if the u.s. dollar appreciates relative to the local currencies of our customers , then the prices of our products correspondingly increase for such customers . such an effect could adversely impact sales of our products to such customers and result in longer sales cycles , difficulties in collection of accounts receivable , slower adoption of new technologies and increased price competition in the affected countries . further , if the u.s. dollar were to weaken against many major currencies , there can be no assurance that a weaker dollar would lead to growth in capital spending . in addition , industry consolidation has in the past constrained , and may in the future constrain , capital spending by our customers . also , if our product portfolio and product development plans do not position us well to capture an increased portion of the capital spending of customers in the markets on which we focus , our revenue may decline . historically , a majority of our revenue has been derived from relatively few customers , due in part to the consolidation of the ownership of cable television and direct broadcast satellite system companies . however , in the last two years , revenue from our ten largest customers has decreased as a percentage of revenue , due to our growing customer base , in part as a result of the acquisition of scopus and omneon . sales to our ten largest customers in 42 2010 , 2009 and 2008 accounted for approximately 44 % , 47 % and 58 % of revenue , respectively . although we are attempting to broaden our customer base by penetrating new markets and further expanding internationally , we expect to see continuing industry consolidation and customer concentration . during 2010 , 2009 and 2008 , revenue from comcast accounted for 17 % , 16 % and 20 % , respectively , of our revenue . sales to echostar accounted for 12 % of net revenue in 2008. the loss of comcast or any other significant customer , any material reduction in orders by comcast or any significant customer , or our failure to qualify our new products with a significant customer could materially and adversely affect our operating results , financial condition and cash flows . in addition , we are involved in most quarters in one or more relatively large individual transactions , including , from time to time , projects in which we act much like a systems integrator . a decrease in the number of the relatively larger individual transactions in which we are involved in any quarter could adversely affect our operating results for that quarter . in addition , historically , we have been dependent upon capital spending in the cable and satellite industry . we are attempting to further diversify our customer base beyond cable and satellite customers , including to the telco and broadcast and media markets . several major telcos have rebuilt or are upgrading their networks to offer bundled video , voice and data services . in order to be successful in this market , we may need to continue to build alliances with telco equipment manufacturers , adapt our products for telco applications , take orders at prices resulting in lower margins , and build internal expertise to handle the particular contractual and technical demands of the telco industry . in addition , telco video deployments , including recent trials of mobile video services , are subject to delays in completion , as video processing technologies and video business models are relatively new to most telcos and many of their largest suppliers . implementation issues with our products or those of other vendors have caused , and may continue to cause , delays in project completion for our customers and delay our recognition of revenue . we often recognize a substantial portion of our quarterly revenues in the last month of the quarter . story_separator_special_tag based on an agreement entered into on january 15 , 2009 to settle its then outstanding patent

the year ended december 31 , 2008. in other pending litigation , harmonic believes that it either has meritorious defenses with respect to those actions and claims or is unable to predict the impact of an adverse action and , accordingly , no loss contingencies for those matters have been accrued . there can be no assurance , however , that we will prevail . an unfavorable outcome of legal proceedings could have a material adverse effect on our business , financial position , operating results or cash flows . accounting for income taxes in preparing our financial statements , we estimate our income taxes for each of the jurisdictions in which we operate . this involves estimating our actual current tax exposures and assessing temporary differences resulting from differing treatment of items , such as reserves and accruals , for tax and accounting purposes . these differences result in deferred tax assets and liabilities , which are included within our consolidated balance sheet . significant management judgment is required in determining our provision for income taxes , our deferred tax assets and liabilities and our future taxable income for purposes of assessing our ability to realize any future benefit from our deferred tax assets . in the event that actual results differ from these estimates or we adjust these estimates in future periods , our operating results and financial position could be materially affected . during the year ended december 31 , 2008 , a full release of the valuation allowance against our net deferred tax assets in the united states and certain foreign jurisdictions , based on our judgment that it is more-likely-than-not that our deferred tax assets in the united states and certain foreign jurisdictions will be recovered from future taxable income , resulted in a benefit from income taxes of $ 53.5 million recorded in our consolidated statements of operations and a $ 3.3 million reduction in goodwill . we are subject to examination of our income tax returns by various tax authorities on a periodic basis . we regularly assess the likelihood of adverse outcomes resulting from such examinations to determine the adequacy of our provision for income taxes . we apply the provisions of the applicable accounting guidance regarding accounting for uncertainty in income taxes which requires application of a more-likely-than-not threshold to the recognition and derecognition of uncertain tax positions . if the recognition threshold is met , the applicable accounting guidance permits us to recognize a tax benefit measured at the largest amount of tax benefit that , in our judgment , is more than fifty percent likely to be realized upon settlement . it further requires that a change in judgment related to the expected ultimate resolution of uncertain tax positions be recognized in earnings in the quarter of such change . we have been notified by the internal revenue service that our 2008 and 2009 u.s. corporate income tax returns have been selected for audit , which is expected to commence in the second quarter of 2011. if upon the conclusion of these audits , the ultimate determination of taxes owed in the u.s. is for an 47 amount in excess of the tax provision we have recorded in the applicable period , our overall tax expense , effective tax rate and cash flows could be adversely impacted in the period of adjustment . we file annual income tax returns in multiple taxing jurisdictions around the world . a number of years may elapse before an uncertain tax position is audited and finally resolved . while it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position , we believe that our reserves for income taxes reflect the most likely outcome . we adjust these reserves as well as the related interest and penalties , in light of changing facts and circumstances . if our estimate of tax liabilities proves to be less than the ultimate assessment , a further charge to expense would result . if payment of these amounts ultimately proves to be unnecessary , the reversal of the liabilities would result in tax benefits being recognized in the period when we determine the liabilities are no longer necessary . any changes in estimate , or settlement of any particular position , could have a material impact on our operating results , financial condition and cash flows . stock-based compensation harmonic measures and recognizes compensation expense for all share-based payment awards made to employees and directors , including stock options , restricted stock units and awards related to our employee stock purchase plan ( espp ) based upon the grant-date fair value of those awards . stock-based

million , respectively . applicable accounting guidance requires companies to estimate the fair value of share-based payment awards on the date of grant . the value of the portion of the award that is

date using the black-scholes option pricing model . the company 's determination of fair value of stock options on the date of grant , using an option-pricing model , is affected by the company 's
