Accounting Policies [Abstract]
 
Principles of Consolidation
The Consolidated Financial Statements include the accounts of Acuity Brands and its wholly-owned subsidiaries after elimination of significant intercompany transactions and accounts.
  
Revenue Recognition
The Company records revenue when the following criteria are met: persuasive evidence of an arrangement exists, delivery has occurred, the Company’s price to the customer is fixed and determinable, and collectability is reasonably assured. Delivery is not considered to have occurred until the customer assumes the risks and rewards of ownership. Customers take delivery at the time of shipment for terms designated free on board shipping point. For sales designated free on board destination, customers take delivery when the product is delivered to the customer’s delivery site. Provisions for certain rebates, sales incentives, product returns, and discounts to customers are recorded in the same period the related revenue is recorded. The Company also maintains one-time or on-going marketing and trade-promotion programs with certain customers that require the Company to estimate and accrue the expected costs of such programs. These arrangements include cooperative marketing programs, merchandising of the Company’s products, and introductory marketing funds for new products and other trade-promotion activities conducted by the customer. Costs associated with these programs are reflected within the Company’s Consolidated Statements of Income in accordance with the Accounting Standards Codification (“ASC”) Topic 605, Revenue Recognition (“ASC 605”), which in most instances requires such costs be recorded as a reduction of revenue.
The Company provides for limited product return rights to certain distributors and customers primarily for slow moving or damaged items subject to certain defined criteria. The Company monitors product returns and, at the time revenue is recognized, records a provision for the estimated amount of future returns based primarily on historical experience and specific notification of pending returns. Although historical product returns generally have been within expectations, there can be no assurance that future product returns will not exceed historical amounts. A significant increase in product returns could have a material impact on the Company’s operating results in future periods.
Revenue is earned on services and the sale of products. Revenue is recognized for the sale of products when the above criteria are met and for services rendered in the period of performance.
  
Revenue Recognition for Arrangements with Multiple Deliverables
A small portion of the Company's revenues are derived from the combination of any or all of: (i) the sale and license of its products, (ii) fees associated with training, installation, and technical support services, and (iii) monitoring and lighting control services. Certain agreements, particularly related to lighting controls systems, represent multiple-element arrangements that include tangible products that contain software that is essential to the functionality of the systems and undelivered elements that primarily relate to installation and monitoring and lighting control services. The undelivered elements associated with installations and monitoring and lighting control services are reviewed and analyzed to determine separability in relation to the delivered elements and appropriate pricing treatment based on (a) vendor-specific objective evidence, (b) third-party evidence, or (c) management estimates. If deemed separate units of accounting, the revenue and associated cost of sales related to the delivered elements are recognized at the time of delivery, while those related to the undelivered elements are recognized appropriately based on the period of performance. If the separation criterion for the undelivered elements is not met due to the undelivered elements being essential to the functionality of the lighting controls systems, all revenue and cost of sales attributable to the contract are deferred at the time of sale and are both generally recognized on a straight-line basis over the respective contract periods.
  
Use of Estimates
The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates.
  
Cash and Cash Equivalents
Cash in excess of daily requirements is invested in time deposits and marketable securities and is included in the accompanying balance sheets at fair value. Acuity Brands considers time deposits and marketable securities with an original maturity of three months or less when purchased to be cash equivalents.
  
Accounts Receivable
The Company records accounts receivable at net realizable value. This value includes an allowance for estimated uncollectible accounts to reflect losses anticipated on accounts receivable balances. The allowance is based on historical write-offs, an analysis of past due accounts based on the contractual terms of the receivables, and economic status of customers, if known.
  
Reclassifications
Certain prior-period amounts have been reclassified to conform to the current year presentation.
  
Inventories
Inventories include materials, direct labor, in-bound freight, and related manufacturing overhead, are stated at the lower of cost (on a first-in, first-out or average cost basis) or market
  
Subsequent Events
The Company has evaluated subsequent events for recognition and disclosure for occurrences and transactions after the date of the consolidated financial statements at August 31, 2012.
  
Intangible Assets
Through multiple acquisitions, the Company acquired intangible assets consisting primarily of trademarks and trade names associated with specific products with finite lives, definite-lived distribution networks, patented technology, non-compete agreements, and customer relationships, which are amortized over their estimated useful lives. Indefinite lived intangible assets consist of trade names that are expected to generate cash flows indefinitely. Significant estimates and assumptions were used to determine the fair value of these acquired intangible assets, including estimated future net sales, customer attrition rates, royalty rates, and discount rates.
  
Goodwill and Other Intangibles
The Company tests indefinite lived intangible assets and goodwill for impairment on an annual basis or more frequently as facts and circumstances change, as required by ASC Topic 350, Intangibles — Goodwill and Other (“ASC 350”). The goodwill impairment test has three steps: a qualitative review and a two-step quantitative method. The preliminary step (“Step 0”) allows for a qualitative analysis to determine the likelihood of impairment. If the qualitative review results in a more likely than not probability of impairment, the first quantitative step is required. The first step identifies potential impairments by comparing the fair value of a reporting unit with its carrying value, including goodwill. The fair values are determined based on a combination of valuation techniques including the expected present value of future cash flows, a market multiple approach, and a comparable transaction approach. If the fair value of a reporting unit exceeds the carrying value, goodwill is not considered impaired and the second step is not necessary. If the carrying value of a reporting unit exceeds the fair value, the second step calculates the possible impairment loss by comparing the implied fair value of goodwill with the carrying value. If the implied fair value of the goodwill is less than the carrying value, an impairment charge is recorded. The impairment test for unamortized trade names consists of comparing the fair value of the asset with its carrying value. The Company estimates the fair value of unamortized trade names using a fair value model based on discounted future cash flows. If the carrying amount exceeds the measured fair value, an impairment loss would be recorded in the amount of the excess. Significant assumptions, including estimated future net sales, operating margins, royalty rates, and discount rates, were used in the determination of estimated fair value for indefinite lived intangible assets. Prior to fiscal 2012, similar assumptions were used in determining the estimated fair value of goodwill. In fiscal 2012, certain qualitative factors and judgment were used to determine the likelihood of goodwill impairment for the Company’s one reporting unit.
  
Shipping and Handling Fees and Costs
The Company includes shipping and handling fees billed to customers in Net Sales. Shipping and handling costs associated with inbound freight and freight between manufacturing facilities and distribution centers are generally recorded in Cost of Products Sold. Other shipping and handling costs are included in Selling, Distribution, and Administrative Expenses
  
Share-Based Compensation
The Company recognizes compensation cost relating to share-based payment transactions in the financial statements based on the estimated fair value of the equity or liability instrument issued. The Company accounts for stock options, restricted shares, and share units representing certain deferrals into the Director Deferred Compensation Plan or the Supplemental Deferred Savings Plan (both of which are discussed further in the Share-Based Payments footnote) based on the grant-date fair value estimated under the current provisions of ASC Topic 718, Compensation — Stock Compensation (“ASC 718”).
  
Depreciation
For financial reporting purposes, depreciation is determined principally on a straight-line basis using estimated useful lives of plant and equipment (10 to 40 years for buildings and related improvements and 3 to 15 years for machinery and equipment), while accelerated depreciation methods are used for income tax purposes. Leasehold improvements are amortized over the shorter of the life of the lease or the estimated useful life of the improvement.
  
Research and Development
Research and development (“R&D”) expense, which is included in Selling, Distribution, and Administrative Expenses in the Company’s Consolidated Statements of Income, is expensed as incurred.
  
Advertising
Advertising costs are expensed as incurred and are included within Selling, Distribution, and Administrative Expenses in the Company’s Consolidated Statements of Income.
  
Interest Expense, Net
Interest expense, net, is comprised primarily of interest expense on long-term debt, revolving credit facility borrowings, and loans collateralized by assets related to a company-owned life insurance program, partially offset by interest income on cash and cash equivalents.
  
Foreign Currency Transaction
The functional currency for the foreign operations of the Company is the local currency. The translation of foreign currencies into U.S. dollars is performed for balance sheet accounts using exchange rates in effect at the balance sheet dates and for revenue and expense accounts using a weighted average exchange rate each month during the year. The gains or losses resulting from the balance sheet translation are included in Comprehensive Income in the Consolidated Statements of Stockholders’ Equity and Comprehensive Income and are excluded from net income.
  
Income Taxes
The Company is taxed at regular corporate rates after adjusting income reported for financial statement purposes for certain items that are treated differently for income tax purposes. Deferred income tax expenses (benefits) result from changes during the year in cumulative temporary differences between the tax basis and book basis of assets and liabilities.
