Goodwill and Other Intangible Assets [Abstract]
GOODWILL AND OTHER INTANGIBLE ASSETS	NOTE 5 — GOODWILL AND OTHER INTANGIBLE ASSETS The Company tests for impairment of goodwill by estimating the fair value of each reporting unit compared to its carrying value. The Company’s reporting units are based on its internal reporting structure and represent an operating segment or a reporting level below an operating segment. Additionally, the reporting units are aggregated based upon similar economic characteristics, nature of products and services, nature of production processes, type of customers and distribution methods. The Company has determined its operating units that have a significant amount of goodwill to be in the Americas Recycling and Americas Fabrication segments. The Company uses a discounted cash flow model to calculate the fair value of its reporting units. The model includes a number of significant assumptions and estimates regarding future cash flows including discount rates, volumes, prices, capital expenditures and the impact of current market conditions. These estimates could be materially impacted by adverse changes in market conditions. The Company performs the goodwill impairment test in the fourth quarter each fiscal year and when changes in circumstances indicate an impairment event may have occurred. There were no triggering events during the third quarter of 2011. The total gross carrying amounts of the Company’s intangible assets that were subject to amortization were $70.1 million and $73.9 million at May 31, 2011 and August 31, 2010, respectively, and are included in other noncurrent assets. Aggregate amortization expense for intangible assets for the three months ended May 31, 2011 and 2010 was $2.4 million and $2.7 million, respectively. Aggregate amortization expense for intangible assets for the nine months ended May 31, 2011 and 2010 was $7.4 million and $11.3 million, respectively.

The entire disclosure for the aggregate amount of goodwill and a description of intangible assets, which may include (a) for amortizable intangible assets (also referred to as finite-lived intangible assets), the carrying amount, the amount of any significant residual value, and the weighted-average amortization period, (b) for intangible assets not subject to amortization (also referred to as indefinite-lived intangible assets), the carrying amount, and (c) the amount of research and development assets acquired and written off in the period, including the line item in the income statement in which the amounts written off are aggregated, if not readily apparent from the income statement. Also discloses (a) for amortizable intangibles assets in total and by major class, the gross carrying amount and accumulated amortization, the total amortization expense for the period, and the estimated aggregate amortization expense for each of the five succeeding fiscal years, (b) for intangible assets not subject to amortization the carrying amount in total and by major class, and (c) for goodwill, in total and for each reportable segment, the changes in the carrying amount of goodwill during the period (including the aggregate amount of goodwill acquired, the aggregate amount of impairment losses recognized, and the amount of goodwill included in the gain (loss) on disposal of a reporting unit). If any part of goodwill has not been allocated to a reportable segment, discloses the unallocated amount and the reasons for not allocating. For each impairment loss recognized related to an intangible asset (excluding goodwill), discloses: (a) a description of the impaired intangible asset and the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method for determining fair value, (c) the caption in the income statement or the statement of activities in which the impairment loss is aggregated, and (d) the segment in which the impaired intangible asset is reported. For each goodwill impairment loss recognized, discloses: (a) a description of the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method of determining the fair value of the associated reporting unit, and (c) if a recognized impairment loss is an estimate not finalized and the reasons why the estimate is not final. May also disclose the nature and amount of any significant adjustments made to a previous estimate of an impairment loss.
