Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Acuity Brands, Inc. (“Acuity Brands”) is the parent company of Acuity Brands Lighting, Inc. (“ABL”) and other subsidiaries (Acuity Brands, ABL, and such other subsidiaries are collectively referred to herein as the “Company”) and was incorporated in 2001 under the laws of the State of Delaware. The Company is one of the world’s leading providers of lighting and building management solutions and services for commercial, institutional, industrial, infrastructure, and residential applications throughout North America and select international markets. The Company’s lighting and building management solutions include devices such as luminaires, lighting controls, controllers for various building systems, power supplies, prismatic skylights, and drivers, as well as integrated systems designed to optimize energy efficiency and comfort for various indoor and outdoor applications. Additionally, the Company continues to expand its solutions portfolio to provide a host of other economic benefits, including software and services that enable the Internet of Things (“IoT”). The Company's IoT solutions provide customers with access to robust data analytics; support the advancement of smart buildings, smart cities, and the smart grid; and allow businesses to develop custom applications to scale their operations. The Company has one reportable segment serving the North American lighting market and select international markets. The Consolidated Financial Statements have been prepared by the Company in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and present the financial position, results of operations, and cash flows of Acuity Brands and its wholly-owned subsidiaries. These unaudited interim consolidated financial statements reflect all normal and recurring adjustments that are, in the opinion of management, necessary to present fairly the Company’s consolidated financial position as of February 28, 2018, the consolidated comprehensive income for the three and six months ended February 28, 2018 and 2017, and the consolidated cash flows for the six months ended February 28, 2018 and 2017. Certain information and footnote disclosures normally included in the Company’s annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. However, the Company believes that the disclosures included herein are adequate to make the information presented not misleading. These financial statements should be read in conjunction with the audited consolidated financial statements of the Company as of and for the three years ended August 31, 2017 and notes thereto included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on October 26, 2017 (File No. 001-16583) (“Form 10-K”). The results of operations for the three and six months ended February 28, 2018 and 2017 are not necessarily indicative of the results to be expected for the full fiscal year due primarily to seasonality, which results in the net sales and net income of the Company generally being higher in the second half of its fiscal year, the impact of any acquisitions, and, among other reasons, the continued uncertainty of general economic conditions that may impact the key end markets of the Company for the remainder of fiscal 2018.

Significant Accounting Policies	Feb. 28, 2018
Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies 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. Reclassifications Certain prior-period amounts have been reclassified to conform to the current year presentation. No material reclassifications occurred during the current period. Refer to the New Accounting Pronouncements footnote for additional information regarding retrospective reclassifications related to accounting standards adopted in the current year.

Business Combinations [Abstract]
Acquisitions and Investments	Acquisitions and Investments The Company does not consider acquisitions a critical element of its strategy but seeks opportunities for growth through acquisitions and investments. Acquisitions and investments are made with the intent to further expand and complement the Company's portfolio of solutions. There was one acquisition during the six months ended February 28, 2018. No acquisitions occurred during fiscal 2017. Lucid Design Group, Inc. On February 12, 2018, using cash on hand, the Company acquired Lucid Design Group, Inc. (“Lucid”). Lucid is headquartered in Oakland, California and provides a data and analytics platform to make data-driven decisions to improve building efficiency and drive energy conservation and savings. The operating results of Lucid have been included in the Company's consolidated financial statements since the date of acquisition and are not material to the Company's financial condition, results of operations, or cash flows. Preliminary amounts related to the acquisition accounting are reflected in the Consolidated Balance Sheets as of February 28, 2018. These amounts are deemed to be provisional until disclosed otherwise, as the Company continues to gather information related to the identification and valuation of intangible and other acquired assets and liabilities.

New Accounting Pronouncements	Feb. 28, 2018
Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Accounting Standards Adopted in Fiscal 2018 In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Improvements to Employee Share-Based Payment Accounting, (“ASU 2016-09”), which changes certain aspects of accounting for share-based payments to employees. The standard requires that all excess tax benefits and deficiencies previously recorded as additional paid-in capital be prospectively recorded in income tax expense, which could create volatility in the Company's effective income tax rate on a quarter by quarter basis due primarily to fluctuations in the Company's stock price and the timing of stock option exercises and vesting of restricted share grants. The standard also requires excess tax benefits to be presented as an operating activity on the statement of cash flows rather than as a financing activity and taxes paid for employee withholdings to be presented as a financing activity. The Company adopted ASU 2016-09 effective as of September 1, 2017. Excess tax benefits and deficiencies are recorded within Income tax (benefit) expense within the Consolidated Statements of Comprehensive Income on a prospective basis as required by the standard; however, the Company elected to present changes to the statement of cash flows on a retrospective basis as allowed by the standard in order to maintain comparability between fiscal years. As such, cash flows from operations for the six months ended February 28, 2017 increased $18.4 million, with a corresponding decrease to cash flows from financing activities, compared to amounts previously reported. In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”), which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the U.S. Tax Cuts and Jobs Act (the “TCJA”) signed into law in December 2017. The Company adopted ASU 2018-02 effective as of the beginning of the current reporting period and recorded a reclassification for the stranded tax effects resulting from the TCJA from Accumulated other comprehensive loss to Retained earnings in the amount of $11.1 million on the Consolidated Balance Sheets during the second quarter of fiscal 2018. Refer to the Income Taxes footnote for further details. Accounting Standards Yet to Be Adopted In March 2017, the FASB issued ASU No. 2017-07, Compensation — Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (“ASU 2017-07”), which will change the presentation of net periodic benefit cost related to employer sponsored defined benefit plans and other postretirement benefits. Service cost will be included within the same income statement line item as other compensation costs arising from services rendered during the period, while other components of net periodic benefit pension cost will be presented separately outside of operating income. Additionally, only service costs may be capitalized in assets. ASU 2017-07 is effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2017. The provisions of ASU 2017-07 are not expected to have a material impact on the Company's financial condition, results of operations, or cash flows. In January 2017, the FASB issued ASU No. 2017-01, Clarifying the Definition of a Business (“ASU 2017-01”), which requires an evaluation of whether substantially all of the fair value of assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If so, the transaction does not qualify as a business. The guidance also requires an acquired business to include at least one substantive process and narrows the definition of outputs. ASU 2017-01 is effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2017. The Company is currently evaluating the impact of the provisions of ASU 2017-01 and intends to implement the standard as required in fiscal 2019. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (“ASU 2016-15”), which is intended to reduce the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows including debt prepayment and extinguishment costs, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, and proceeds from the settlement of corporate-owned life insurance. ASU 2016-15 is effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2017. The Company intends to implement the standard as required in fiscal 2019, and the provisions of ASU 2016-15 are not expected to have a material impact on the Company's financial statement disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”), which requires lessees to include most leases on the balance sheet. ASU 2016-02 is effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2018. In January 2018, the FASB issued ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842, which establishes an optional transition practical expedient when applying the guidance in ASU 2016-02 and has the same effective date as the original standard. The Company is currently evaluating the impact of the provisions of ASU 2016-02 and intends to implement the standard as required in fiscal 2020. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which will replace most existing revenue recognition guidance in U.S. GAAP. Since the issuance of ASU 2014-09, the FASB released several amendments to improve and clarify the implementation guidance, as well as to change the effective date. These standards have been collectively codified within Accounting Standards Codification (“ASC") 606, Revenue from Contracts with Customers (“ASC 606”). ASC 606 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The standard also requires additional disclosures about the nature, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. ASC 606 permits two transition methods: the full retrospective method and the modified retrospective method. Under the full retrospective method, the standard would be applied to each prior reporting period presented with the cumulative effect of applying the standard recognized at the earliest period shown. Under the modified retrospective method, the cumulative effect of applying the standard would be recognized at the date of initial application. ASC 606 is effective for annual reporting periods beginning after December 15, 2017. The Company will adopt the requirements of the new standard on September 1, 2018. The Company has an implementation team tasked with identifying potential differences that will result from applying the new revenue recognition standard to the Company's contracts with its customers. The implementation team reports the findings and progress of the project to management on a frequent basis and to the Audit Committee of the Board of Directors on a quarterly basis. The implementation team has completed its initial phase of contract reviews and continues to evaluate the results of those reviews with respect to potential changes from adopting the new standard on the Company's consolidated financial statements. Management anticipates the most significant changes will relate to additional deferral of revenue recognition for certain services provided and the gross presentation of right of return assets and refund liabilities for sales with a right of return. Based on the current portfolio of the Company's revenue generating activities, these changes are not expected to have a material impact on the Company's consolidated financial condition, results of operations, or cash flows. Additionally, the implementation team is in the process of identifying appropriate changes to the Company's business processes, systems, and controls to support recognition and disclosure under the new standard. Based on the implementation team's current findings and the overall expected immaterial impact of adoption, the implementation team is currently evaluating which adoption method would provide the most meaningful information to the Company's stakeholders. All other newly issued accounting pronouncements not yet effective have been deemed either immaterial or not applicable.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

The Company determines fair value measurements based on the assumptions a market participant would use in pricing an asset or liability. ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), establishes a three level hierarchy making a distinction between market participant assumptions based on (i) unadjusted quoted prices for identical assets or liabilities in an active market (Level 1), (ii) quoted prices in markets that are not active or inputs that are observable either directly or indirectly for substantially the full term of the asset or liability (Level 2), and (iii) prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement (Level 3).

The Company's cash and cash equivalents (Level 1), which are required to be carried at fair value and measured on a recurring basis, were $229.8 million and $311.1 million as of February 28, 2018 and August 31, 2017, respectively.

The Company utilizes valuation methodologies to determine the fair values of its financial assets and liabilities in conformity with the concepts of “exit price” and the fair value hierarchy as prescribed in ASC 820. All valuation methods and assumptions are validated at least quarterly to ensure the accuracy and relevance of the fair values. There were no material changes to the valuation methods or assumptions used to determine fair values during the current period.

The Company used quoted market prices to determine the fair value of Level 1 assets and liabilities. No transfers between the levels of the fair value hierarchy occurred during the current fiscal period. In the event of a transfer in or out of a level within the fair value hierarchy, the transfers would be recognized on the date of occurrence.

Disclosures of fair value information about financial instruments (whether or not recognized in the balance sheet), for which it is practicable to estimate that value, are required each reporting period in addition to any financial instruments carried at fair value on a recurring basis as prescribed by ASC 825, Financial Instruments (“ASC 825”). In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows.

The carrying values and estimated fair values of certain of the Company’s financial instruments were as follows at February 28, 2018 and August 31, 2017 (in millions):



	February 28, 2018				August 31, 2017
	Carrying Value		Fair Value		Carrying Value		Fair Value
Senior unsecured public notes, net of unamortized discount and deferred costs	$	349.3	$	369.3	$	349.1	$	379.7
Industrial revenue bond	4.0		4.0		4.0		4.0
Bank loans	3.6		3.6		3.8		3.8

The senior unsecured public notes are carried at the outstanding balance, net of unamortized bond discount and deferred costs, as of the end of the reporting period. Fair value is estimated based on discounted future cash flows using rates currently available for debt of similar terms and maturity (Level 2).

The industrial revenue bond is carried at the outstanding balance as of the end of the reporting period. The industrial revenue bond is a tax-exempt, variable-rate instrument that resets on a weekly basis; therefore, the Company estimates that the face amount of the bond approximates fair value as of February 28, 2018 based on bonds of similar terms and maturity (Level 2).

The bank loans are carried at the outstanding balance as of the end of the reporting period. Fair value is estimated based on discounted future cash flows using rates currently available for debt of similar terms and maturity (Level 2).

ASC 825 excludes certain financial instruments and all nonfinancial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented do not represent the underlying value to the Company. In many cases, the fair value estimates cannot be substantiated by comparison to independent markets, nor can the disclosed value be realized in immediate settlement of the instruments. In evaluating the Company’s management of liquidity and other risks, the fair values of all assets and liabilities should be taken into consideration, not only those presented above.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Goodwill and Intangible Assets

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and 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.

The Company recorded amortization expense of $6.7 million and $7.8 million during the three months ended February 28, 2018 and 2017, respectively, and $13.3 million and $13.7 million during the six months ended February 28, 2018 and 2017, respectively. Amortization expense is generally recorded on a straight-line basis and is expected to be approximately $26.3 million in fiscal 2018, $26.0 million in fiscal 2019, $26.0 million in fiscal 2020, $23.1 million in fiscal 2021, and $21.4 million in fiscal 2022.

These projections exclude the impact to amortization expense related to potential intangible assets associated with the Lucid transaction, which is not expected to be material to the Company's operations. The acquisition accounting and the related useful lives and amortization for the Lucid acquisition are preliminary as the Company continues to gather information related to the identification and valuation of intangible assets acquired.

The change in the carrying amount of goodwill during the six months ended February 28, 2018 is summarized below (in millions):



Balance at August 31, 2017	$	900.9
Additions from acquired businesses	13.4
Foreign currency translation adjustments	(2.4		)
Balance at February 28, 2018	$	911.9

Earnings Per Share [Abstract]

Earnings per Share

Earnings Per Share

Basic earnings per share for the periods presented is computed by dividing net earnings available to common stockholders by the weighted average number of common shares outstanding. Diluted earnings per share is computed similarly but reflects the potential dilution that would occur if dilutive options were exercised, all unvested share-based payment awards were vested, and other distributions related to deferred stock agreements were incurred.

The following table calculates basic earnings per common share and diluted earnings per common share for the three and six months ended February 28, 2018 and 2017 (in millions, except per share data):

Debt

Debt Disclosure [Abstract]

Debt

Lines of Credit

On August 27, 2014, the Company executed a $250.0 million revolving credit facility (the “Revolving Credit Facility”). The Revolving Credit Facility will mature, and all amounts outstanding will be due and payable, on August 27, 2019. Generally, amounts outstanding under the Revolving Credit Facility bear interest at a Eurocurrency Rate. Eurocurrency Rate advances can be denominated in a variety of currencies, including U.S. Dollars, and amounts outstanding bear interest at a periodic fixed rate equal to the London Inter Bank Offered Rate (“LIBOR”) for the applicable currency plus a margin as determined by the Company's leverage ratio (“Applicable Margin”). The Applicable Margin is based on the Company’s leverage ratio, as defined in the Revolving Credit Facility, with such margin ranging from 1.000% to 1.575%. The Company had no borrowings outstanding under the Revolving Credit Facility as of February 28, 2018. Additionally, the Company is required to pay certain fees in connection with the Revolving Credit Facility, including administrative service fees and an annual facility fee. The annual facility fee is payable quarterly, in arrears, and is determined by the Company’s leverage ratio as defined in the Revolving Credit Facility. This facility fee ranges from 0.125% to 0.300% of the aggregate $250.0 million commitment of the lenders under the Revolving Credit Facility.

The Revolving Credit Facility contains financial covenants, including a minimum interest coverage ratio (“Minimum Interest Coverage Ratio”) and a leverage ratio (“Maximum Leverage Ratio”) of total indebtedness to earnings before interest, taxes, depreciation, and amortization expense (“EBITDA”), as such terms are defined in the Revolving Credit Facility agreement. These ratios are computed at the end of each fiscal quarter for the most recent 12-month period. The Revolving Credit Facility allows for a Minimum Interest Coverage Ratio of 2.50 and a Maximum Leverage Ratio of 3.50, subject to certain conditions defined in the financing agreement.

As of February 28, 2018, the Company was in compliance with all financial covenants under the Revolving Credit Facility. As of February 28, 2018, the Company had outstanding letters of credit totaling $10.2 million, primarily for securing collateral requirements under the Company's casualty insurance programs and for providing credit support for the Company’s industrial revenue bond (not an outstanding amount under the Revolving Credit Facility). At February 28, 2018, the Company had additional borrowing capacity under the Revolving Credit Facility of $244.7 million under the most restrictive covenant in effect at the time, which represents the full amount of the Revolving Credit Facility less outstanding letters of credit of $5.3 million issued under the Revolving Credit Facility.

Long-term Debt

At February 28, 2018, the Company had $350.0 million of publicly-traded, senior unsecured notes outstanding at a 6% interest rate that are scheduled to mature in December 2019 (the “Unsecured Notes”) and $4.0 million of tax-exempt industrial revenue bonds that are scheduled to mature in 2021. The Company also had $3.6 million outstanding under fixed-rate bank loans. Further discussion of the Company's long-term debt is included within the Debt and Lines of Credit footnote of the Notes to Consolidated Financial Statements within the Company’s Form 10-K.

Interest Expense, net

Interest expense, net, is comprised primarily of interest expense on long-term debt, obligations in connection with non-qualified retirement benefits, and Revolving Credit Facility borrowings, partially offset by interest income earned on cash and cash equivalents.

The following table summarizes the components of interest expense, net for the three and six months ended February 28, 2018 and 2017 (in millions):



	Three Months Ended						Six Months Ended

Commitments and Contingencies

6 Months Ended

Feb. 28, 2018

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

In the normal course of business, the Company is subject to the effects of certain contractual stipulations, events, transactions, and laws and regulations that may, at times, require the recognition of liabilities, such as those related to self-insurance reserves and claims, legal and contractual issues, environmental laws and regulations, guarantees, and indemnities. The Company establishes reserves when the associated costs related to uncertainties or guarantees become probable and can be reasonably estimated. For the period ended February 28, 2018, no material changes have occurred in the Company's reserves for self-insurance, litigation, environmental matters, guarantees and indemnities, or relevant events and circumstances, from those disclosed in the Commitments and Contingencies footnote of the Notes to Consolidated Financial Statements within the Company's Form 10-K.

Trade Compliance Matters

In the course of routine reviews of import and export activity, the Company previously determined that it misclassified and/or inaccurately valued certain international shipments of products. The Company is conducting a detailed review of this activity to determine the extent of any liabilities and the appropriate remedial measures. At this time, the Company is unable to determine the likelihood or amount of any loss associated with these shipments.

Product Warranty and Recall Costs

The Company's products generally have a standard warranty term of five years. The Company records an allowance for the estimated amount of future warranty costs when the related revenue is recognized. Estimated costs related to product recalls based on a formal campaign soliciting repair or return of that product are accrued when they are deemed to be probable and can be reasonably estimated. Estimated future warranty and recall costs are primarily based on historical experience of identified warranty and recall claims. In certain limited cases, the Company has warranty arrangements for terms that exceed the standard term. Given that these longer-term warranties are not included in the Company’s historical experience, the Company utilizes estimated failure rates from industry sources to determine the potential future warranty cost. However, there can be no assurance that future warranty or recall costs will not exceed historical amounts or that new technology products, which may include extended warranties, may not generate unexpected costs. If actual future warranty or recall costs exceed historical amounts, additional allowances may be required, which could have a material adverse impact on the Company’s results of operations and cash flows.

Reserves for product warranty and recall costs are included in Other accrued liabilities and Other long-term liabilities on the Consolidated Balance Sheets. The changes in the reserves for product warranty and recall costs during the six months ended February 28, 2018 and 2017 are summarized as follows (in millions):



	Six Months Ended
	February 28, 2018			February 28, 2017

Securities Class Action

On January 3, 2018, a shareholder filed a class action complaint in the United States District Court for the District of Delaware against the Company and certain of its officers on behalf of all persons who purchased or otherwise acquired the Company’s stock between June 29, 2016 and April 3, 2017. On February 20, 2018, a different shareholder filed a second class action complaint in the same venue against the same parties on behalf of all persons who purchased or otherwise acquired the Company’s stock between October 15, 2015 and April 3, 2017. A motion to consolidate the cases has been filed and is presently pending, unopposed. The complaints allege that the defendants violated the federal securities laws by making false or misleading statements and/or omitting to disclose material adverse facts that (i) concealed known trends negatively impacting sales of the Company’s products and (ii) overstated the Company’s ability to achieve profitable sales growth. The plaintiffs seek class certification, unspecified monetary damages, costs, and attorneys’ fees. The Company disputes the allegations in the complaints and intends to vigorously defend against the claims. Estimating an amount or range of possible losses resulting from litigation proceedings is inherently difficult, particularly where the matters involve indeterminate claims for monetary damages and are in the stages of the proceedings where key factual and legal issues have not been resolved. For these reasons, the Company is currently unable to predict the ultimate timing or outcome of or reasonably estimate the possible losses or a range of possible losses resulting from the matters described above. The Company is insured, in excess of a self-retention, for Directors and Officers liability.

Other Litigation

The Company is subject to various other legal claims arising in the normal course of business, including patent infringement, employment matters, and product liability claims. Based on information currently available, it is the opinion of management that the ultimate resolution of any such pending and threatened legal proceedings will not have a material adverse effect on the financial condition, results of operations, or cash flows of the Company. However, in the event of unexpected future developments, it is possible that the ultimate resolution of any such matters, if unfavorable, could have a material adverse effect on the financial condition, results of operations, or cash flows of the Company in future periods. The Company establishes reserves for legal claims when associated costs become probable and can be reasonably estimated. The actual costs of resolving legal claims may be substantially higher than the amounts reserved for such claims. However, the Company cannot make a meaningful estimate of actual costs to be incurred that could possibly be higher or lower than the amounts reserved.

Restructuring and Related Activities [Abstract]

Special Charge

During fiscal 2017, the Company recognized pre-tax special charges consisting primarily of severance and employee-related benefit costs for the elimination of certain operations and positions following a realignment of the Company's operating structure, including positions within various selling, distribution, and administrative (“SD&A”) departments. During fiscal 2016, the Company recognized pre-tax special charges primarily related to the Company's continued efforts to integrate recent acquisitions and to streamline the organization by realigning certain responsibilities primarily within various SD&A departments, as well as the consolidation of certain production activities. The Company did not initiate any such actions during fiscal 2018.

Costs reflected within Special charge on the Consolidated Statements of Income for the three and six months ended February 28, 2018 primarily include severance and employee-related costs for the 2017 initiative. Special charges for the six months ended February 28, 2017 primarily reflect lease termination costs associated with fiscal 2016 actions. No special charges were recorded during the three months ended February 28, 2017.

As of February 28, 2018, remaining restructuring reserves were $9.0 million and are included in Accrued compensation and Other long-term liabilities on the Consolidated Balance Sheets. The changes in the reserves related to these programs during the six months ended February 28, 2018 are summarized as follows (in millions):

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On December 22, 2017, the President of the United States signed into law the TCJA, which reduces the federal corporate tax rate from 35% to 21% effective January 1, 2018 and requires a one-time transition tax on accumulated unremitted foreign earnings. Following the enactment of the TCJA, the Company recognized a provisional tax benefit estimate of $31.2 million within Income tax (benefit) expense on the Consolidated Statements of Comprehensive Income. This provisional amount includes a benefit of $32.3 million to decrease the Company's deferred income taxes to a revised statutory federal rate as well as a current estimate for the provision for unremitted foreign earnings of approximately $1.1 million. Amounts reflected in the current period are not finalized as the Company continues to evaluate the impact of the TCJA on these components of the Company's ultimate tax liability. Although the Company is able to make a reasonable estimate of the impact of the corporate rate change to its deferred taxes, further evaluation of the TCJA may change the measurement of, or identify new, deferred tax amounts. Additionally, the Company has not completed its analysis of the total post-1986 earnings and profits not previously subject to income taxes, including the determination of amounts held in cash and other certain assets specified by the TCJA. Upon finalization of this calculation, the provisional amount recorded for unremitted foreign earnings may change. The TCJA also includes a provision for a global intangible low-taxed income (“GILTI”) tax. Companies can either account for taxes on GILTI in the period in which they are incurred or establish deferred tax liabilities for the expected future taxes associated with GILTI. The Company has not yet made a policy election with respect to its treatment of these taxes. Additionally, the Company reclassified $11.1 million from Accumulated other comprehensive loss to Retained earnings in relation to the revaluation of deferred tax assets related to the Company's defined benefit plans during the current period.

Condensed Financial Information of Parent Company Only Disclosure [Abstract]

Supplemental Guarantor Condensed Consolidating Financial Statements

In December 2009, ABL, the 100% owned and principal operating subsidiary of Acuity Brands, refinanced the then current outstanding debt through the issuance of the Notes. See Debt and Lines of Credit footnote for further information.

In accordance with the registration rights agreement by and between ABL and the guarantors to the Notes and the initial purchasers of the Notes, ABL and the guarantors to the Notes filed a registration statement with the SEC for an offer to exchange the Notes for an issue of SEC-registered notes with identical terms. Due to the filing of the registration statement and offer to exchange, the Company determined the need for compliance with Rule 3-10 of SEC Regulation S-X (“Rule 3-10”). In lieu of providing separate audited financial statements for ABL and ABL IP Holding, the Company has included the accompanying Condensed Consolidating Financial Statements in accordance with Rule 3-10(d) of SEC Regulation S-X since the Notes are fully and unconditionally guaranteed by Acuity Brands and ABL IP Holding. The column marked “Parent” represents the financial condition, results of operations, and cash flows of Acuity Brands. The column marked “Subsidiary Issuer” represents the financial condition, results of operations, and cash flows of ABL. The column entitled “Subsidiary Guarantor” represents the financial condition, results of operations, and cash flows of ABL IP Holding. Lastly, the column listed as “Non-Guarantors” includes the financial condition, results of operations, and cash flows of the non-guarantor direct and indirect subsidiaries of Acuity Brands, which consist primarily of foreign subsidiaries. Consolidating adjustments were necessary in order to arrive at consolidated amounts. In addition, the equity method of accounting was used to calculate investments in subsidiaries. Accordingly, this basis of presentation is not intended to present the Company's financial condition, results of operations, or cash flows for any purpose other than to comply with the specific requirements for parent-subsidiary guarantor reporting.

Significant Accounting Policies (Policies)	6 Months Ended
Significant Accounting Policies (Policies)	Feb. 28, 2018
Accounting Policies [Abstract]
Basis of Accounting	The Consolidated Financial Statements have been prepared by the Company in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and present the financial position, results of operations, and cash flows of Acuity Brands and its wholly-owned subsidiaries.
Use of Estimates	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.
Reclassifications	Reclassifications Certain prior-period amounts have been reclassified to conform to the current year presentation. No material reclassifications occurred during the current period.
New Accounting Pronouncements	New Accounting Pronouncements Accounting Standards Adopted in Fiscal 2018 In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Improvements to Employee Share-Based Payment Accounting, (“ASU 2016-09”), which changes certain aspects of accounting for share-based payments to employees. The standard requires that all excess tax benefits and deficiencies previously recorded as additional paid-in capital be prospectively recorded in income tax expense, which could create volatility in the Company's effective income tax rate on a quarter by quarter basis due primarily to fluctuations in the Company's stock price and the timing of stock option exercises and vesting of restricted share grants. The standard also requires excess tax benefits to be presented as an operating activity on the statement of cash flows rather than as a financing activity and taxes paid for employee withholdings to be presented as a financing activity. The Company adopted ASU 2016-09 effective as of September 1, 2017. Excess tax benefits and deficiencies are recorded within Income tax (benefit) expense within the Consolidated Statements of Comprehensive Income on a prospective basis as required by the standard; however, the Company elected to present changes to the statement of cash flows on a retrospective basis as allowed by the standard in order to maintain comparability between fiscal years. As such, cash flows from operations for the six months ended February 28, 2017 increased $18.4 million, with a corresponding decrease to cash flows from financing activities, compared to amounts previously reported. In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”), which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the U.S. Tax Cuts and Jobs Act (the “TCJA”) signed into law in December 2017. The Company adopted ASU 2018-02 effective as of the beginning of the current reporting period and recorded a reclassification for the stranded tax effects resulting from the TCJA from Accumulated other comprehensive loss to Retained earnings in the amount of $11.1 million on the Consolidated Balance Sheets during the second quarter of fiscal 2018. Refer to the Income Taxes footnote for further details. Accounting Standards Yet to Be Adopted In March 2017, the FASB issued ASU No. 2017-07, Compensation — Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (“ASU 2017-07”), which will change the presentation of net periodic benefit cost related to employer sponsored defined benefit plans and other postretirement benefits. Service cost will be included within the same income statement line item as other compensation costs arising from services rendered during the period, while other components of net periodic benefit pension cost will be presented separately outside of operating income. Additionally, only service costs may be capitalized in assets. ASU 2017-07 is effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2017. The provisions of ASU 2017-07 are not expected to have a material impact on the Company's financial condition, results of operations, or cash flows. In January 2017, the FASB issued ASU No. 2017-01, Clarifying the Definition of a Business (“ASU 2017-01”), which requires an evaluation of whether substantially all of the fair value of assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If so, the transaction does not qualify as a business. The guidance also requires an acquired business to include at least one substantive process and narrows the definition of outputs. ASU 2017-01 is effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2017. The Company is currently evaluating the impact of the provisions of ASU 2017-01 and intends to implement the standard as required in fiscal 2019. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (“ASU 2016-15”), which is intended to reduce the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows including debt prepayment and extinguishment costs, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, and proceeds from the settlement of corporate-owned life insurance. ASU 2016-15 is effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2017. The Company intends to implement the standard as required in fiscal 2019, and the provisions of ASU 2016-15 are not expected to have a material impact on the Company's financial statement disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”), which requires lessees to include most leases on the balance sheet. ASU 2016-02 is effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2018. In January 2018, the FASB issued ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842, which establishes an optional transition practical expedient when applying the guidance in ASU 2016-02 and has the same effective date as the original standard. The Company is currently evaluating the impact of the provisions of ASU 2016-02 and intends to implement the standard as required in fiscal 2020. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which will replace most existing revenue recognition guidance in U.S. GAAP. Since the issuance of ASU 2014-09, the FASB released several amendments to improve and clarify the implementation guidance, as well as to change the effective date. These standards have been collectively codified within Accounting Standards Codification (“ASC") 606, Revenue from Contracts with Customers (“ASC 606”). ASC 606 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The standard also requires additional disclosures about the nature, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. ASC 606 permits two transition methods: the full retrospective method and the modified retrospective method. Under the full retrospective method, the standard would be applied to each prior reporting period presented with the cumulative effect of applying the standard recognized at the earliest period shown. Under the modified retrospective method, the cumulative effect of applying the standard would be recognized at the date of initial application. ASC 606 is effective for annual reporting periods beginning after December 15, 2017. The Company will adopt the requirements of the new standard on September 1, 2018. The Company has an implementation team tasked with identifying potential differences that will result from applying the new revenue recognition standard to the Company's contracts with its customers. The implementation team reports the findings and progress of the project to management on a frequent basis and to the Audit Committee of the Board of Directors on a quarterly basis. The implementation team has completed its initial phase of contract reviews and continues to evaluate the results of those reviews with respect to potential changes from adopting the new standard on the Company's consolidated financial statements. Management anticipates the most significant changes will relate to additional deferral of revenue recognition for certain services provided and the gross presentation of right of return assets and refund liabilities for sales with a right of return. Based on the current portfolio of the Company's revenue generating activities, these changes are not expected to have a material impact on the Company's consolidated financial condition, results of operations, or cash flows. Additionally, the implementation team is in the process of identifying appropriate changes to the Company's business processes, systems, and controls to support recognition and disclosure under the new standard. Based on the implementation team's current findings and the overall expected immaterial impact of adoption, the implementation team is currently evaluating which adoption method would provide the most meaningful information to the Company's stakeholders. All other newly issued accounting pronouncements not yet effective have been deemed either immaterial or not applicable.
Methodologies used to determine fair values of financial assets and liabilities	The Company utilizes valuation methodologies to determine the fair values of its financial assets and liabilities in conformity with the concepts of “exit price” and the fair value hierarchy as prescribed in ASC 820. All valuation methods and assumptions are validated at least quarterly to ensure the accuracy and relevance of the fair values. There were no material changes to the valuation methods or assumptions used to determine fair values during the current period.
Recognition of transfers between levels within the fair value hierarchy	The Company used quoted market prices to determine the fair value of Level 1 assets and liabilities. No transfers between the levels of the fair value hierarchy occurred during the current fiscal period. In the event of a transfer in or out of a level within the fair value hierarchy, the transfers would be recognized on the date of occurrence.
