26 the greenbrier companies 2013 annual report we operate two manufacturing facilities in sahagun , mexico , one of which we own and one which is leased . in september 2013 , we were notified by the landlord of our leased facility that the landlord does not intend to renew the lease following the expiration of the lease term in november 2014. while we continue to discuss the potential extension of the lease , we are also planning for alternatives to replace the manufacturing capacity of such facility , including potentially through expanding production capacity at our owned facility in sahagun , mexico or at other manufacturing sites . results of operations the accounting policies of the three segments in which we operate are the same as those described in the summary of significant accounting policies . segment performance is evaluated based on margin . the company 's integrated business model results in selling and administrative costs being intertwined among the segments . currently , greenbrier 's management does not allocate these costs for either external or internal reporting purposes . overview ( in thousands ) 2013 2012 2011 revenue : manufacturing $ 1,215,734 $

0.24 the decrease in revenue for the year ended august 31 , 2013 was primarily the result of a lower volume of deliveries in the manufacturing segment of our business . the increase in revenue for the year ended august 31 , 2012 was primarily the result of higher levels of activity associated with the economic recovery in the freight car market including higher railcar deliveries as a result of increased demand . the decrease in net earnings for the year ended august 31 , 2013 was primarily attributable to a non-cash goodwill impairment charge of $ 71.8 million , net of tax and restructuring charges of $ 1.8 million , net of tax . these were partially offset by an increase in gain on disposition of equipment . the increase in net earnings for the greenbrier companies 2013 annual report 27 the year ended august 31 , 2012 was primarily attributable to an increase in manufacturing margin in 2012 and loss on extinguishment of debt recognized in 2011. these factors were partially offset by higher selling and administrative costs associated with operating at higher production levels in 2012. manufacturing segment manufacturing revenue was $ 1.216 billion , $ 1.254 billion and $ 721.1 million for the years ended august 31 , 2013 , 2012 and 2011. railcar deliveries , which are the primary source of manufacturing revenue , were 11,600 units in 2013 compared to 15,000 units in 2012 and 9,400 units in 2011. manufacturing revenue decreased $ 38.2 million in 2013 compared to 2012 primarily due to a lower volume of deliveries as compared to the prior year . these lower deliveries were a result of a change in product mix to more labor intensive railcar types and lower than expected demand for certain of our products . these factors were partially offset by a higher per unit average selling price as a result of a change in product mix and an increase in marine revenue from the prior year . manufacturing revenue increased $ 532.9 million in 2012 compared to 2011 primarily due to higher railcar deliveries as a result of increased demand and a higher per unit average selling price principally due to a change in product mix . manufacturing margin as a percentage of revenue was 10.9 % in 2013 , 10.5 % in 2012 and 8.3 % in 2011. the increase in 2013 compared to 2012 was primarily the result of a favorable change in product mix and an increase in marine revenue . these factors were partially offset by inefficiencies with ramping up tank car production . the increase in 2012 compared to 2011 was primarily the result of efficiencies from operating at higher production rates and a more favorable pricing environment . in addition , 2011 was impacted by inefficiencies as we ramped up production at idle facilities . wheels , repair & parts segment wheels , repair & parts revenue was $ 469.2 million , $ 481.9 million and $ 452.9 million for the years ended august 31 , 2013 , 2012 and 2011. the $ 12.7 million decrease in revenue in 2013 compared to 2012 was primarily the result of lower demand for wheel set replacements and a decrease in scrap metal pricing and volume . these were partially offset by an increase in demand for repair work . the $ 29.0 million increase in revenue in 2012 compared to 2011 was primarily the result of higher sales volumes of repair and parts due to higher demand . story_separator_special_tag the estimated maintenance liability is based on maintenance histories for each type and age of railcar . these estimates involve judgment as to the future costs of repairs and the types and timing of repairs required over the lease term . as we can not predict with certainty the prices , timing and volume of maintenance needed in the future on railcars under long-term leases , this estimate is uncertain and could be materially different from maintenance requirements . the liability is periodically reviewed and updated based on maintenance trends and known future repair or refurbishment requirements . these adjustments could be material due to the inherent uncertainty in predicting future maintenance requirements . warranty accruals - warranty costs to cover a defined warranty period are estimated and charged to operations . the estimated warranty cost is based on historical warranty claims for each particular product type . for new product types without a warranty history , preliminary estimates are based on historical information for similar product types . these estimates are inherently uncertain as they are based on historical data for existing products and judgment for new products . if warranty claims are made in the current period for issues that have not historically been the subject of warranty claims and were not taken into consideration in establishing the accrual or if claims for issues already considered in establishing the accrual exceed expectations , warranty expense may exceed the accrual for that particular product . conversely , there is the possibility that claims may be lower than estimates . the warranty accrual is periodically reviewed and updated based on warranty trends . however , as we can not predict future claims , the potential exists for the difference in any one reporting period to be material . environmental costs - at times we may be involved in various proceedings related to environmental matters . we estimate future costs for known environmental remediation requirements and accrue for them when it is probable that we have incurred a liability and the related costs can be reasonably estimated based on currently available information . if further developments or resolution of an environmental matter result in facts and circumstances that are significantly different than the assumptions used to develop these reserves , the accrual for environmental remediation could be materially understated or overstated . adjustments to these liabilities are made when additional information becomes available that affects the estimated costs to study or remediate any environmental issues or when expenditures for which reserves are established are made . due to the uncertain nature of estimating potential environmental matters , there can be no assurance that we will not become involved in future litigation or other proceedings or , if we were found to be responsible or liable in any litigation or proceeding , that such costs would not be material to us . revenue recognition - revenue is recognized when persuasive evidence of an arrangement exists , delivery has occurred or services have been rendered , the price is fixed or determinable and collectability is reasonably assured . railcars are generally manufactured , repaired or refurbished and wheels and parts produced under firm orders from third parties . revenue is recognized when these products or services are completed , accepted by an unaffiliated customer and contractual contingencies removed . certain leases are operated under car hire arrangements whereby revenue is earned based on utilization , car hire rates and terms specified in the lease agreement . car hire revenue is reported from a third party source two months in arrears ; however , such revenue the greenbrier companies 2013 annual report 35 is accrued in the month earned based on estimates of use from historical activity and is adjusted to actual as reported . these estimates are inherently uncertain as they involve judgment as to the estimated use of each railcar . adjustments to actual have historically not been significant . revenues from construction of marine barges are either recognized on the percentage of completion method during the construction period or on the completed contract method based on the terms of the contract . under the percentage of completion method , judgment is used to determine a definitive threshold against which progress towards completion can be measured to determine timing of revenue recognition . we sell railcars with leases attached to financial investors . in addition we will often perform management or maintenance services at market rates for these railcars . pursuant to the guidance in asc 840-20-40 , we evaluate the terms of any remarketing agreements and any contractual provisions that represent retained risk and the level of retained risk based on those provisions . we apply a 10 % threshold to determine whether the level of retained risk exceeds 10 % of the individual fair value of the railcars delivered . for any contracts with multiple elements ( i.e . railcars , maintenance , management services , etc ) we allocate revenue among the deliverables primarily based upon objective and reliable evidence of the fair value of each element in the arrangement . if objective and reliable evidence of fair value of any element is not available , we will use the element 's estimated selling price for purposes of allocating the total arrangement consideration among the elements . impairment of long-lived assets - when changes in circumstances indicate the carrying amount of certain long-lived assets may not be recoverable , the assets are evaluated for impairment . if the forecast undiscounted future cash flows are less than the carrying amount of the assets , an impairment charge to reduce the carrying value of the assets to fair value is recognized in the current period . these estimates are based on the best information available at the time of the impairment and could be materially different if circumstances change . if the forecast undiscounted future cash flows exceeded the carrying amount of the assets it would indicate that the assets were
