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 “we,” “our,” “us,” “the Company," or similar references) and was incorporated in 2001 under the laws of the State of Delaware. We are 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. Our 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, we continue to expand our solutions portfolio, including software and services, to provide a host of other economic benefits resulting from data analytics that enables the Internet of Things (“IoT”), supports the advancement of smart buildings, smart cities, and the smart grid, and allows businesses to develop custom applications to scale their operations. We have one reportable segment serving the North American lighting market and select international markets. We prepared the Consolidated Financial Statements in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) to 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 our consolidated financial position as of February 28, 2019, our consolidated comprehensive income for the three and six months ended February 28, 2019 and 2018, and our consolidated cash flows for the six months ended February 28, 2019 and 2018. Certain information and footnote disclosures normally included in our annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. However, we believe 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, 2018 and notes thereto included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on October 25, 2018 (File No. 001-16583) (“Form 10-K”). The results of operations for the three and six months ended February 28, 2019 and 2018 are not necessarily indicative of the results to be expected for the full fiscal year due primarily to seasonality, which results in our net sales and net income generally being higher in the second half of our fiscal year, the impact of any acquisitions, and, among other reasons, the continued uncertainty of general economic conditions that may impact our key end markets for the remainder of fiscal 2019.

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.

Acquisitions and Investments	Acquisitions and Investments No acquisitions were completed during the first six months of fiscal 2019. The following discussion relates to acquisitions completed during fiscal 2018. IOTA Engineering, LLC On May 1, 2018, using cash on hand and borrowings available under existing credit arrangements, we acquired all of the equity interests of IOTA Engineering, LLC (“IOTA”). IOTA is headquartered in Tucson, Arizona and manufactures highly engineered emergency lighting products and power equipment for commercial and institutional applications both in the U.S. and international markets. The operating results of IOTA have been included in our consolidated financial statements since the date of acquisition and are not material to our financial condition, results of operations, or cash flows. Lucid Design Group, Inc. On February 12, 2018, using cash on hand, we acquired all of the equity interests of 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 our consolidated financial statements since the date of acquisition and are not material to our financial condition, results of operations, or cash flows. Accounting for Fiscal 2018 Acquisitions Acquisition-related costs were expensed as incurred. Amounts related to the acquisition accounting for these acquisitions are reflected in the Consolidated Balance Sheets. The aggregate purchase price of these acquisitions reflects total goodwill and identified intangible assets of approximately $77.0 million and $81.8 million, respectively, as of February 28, 2019. Identified intangible assets consist of indefinite-lived marketing-related intangibles as well as definite-lived customer-based and technology-based assets, which have a weighted average useful life of approximately 14 years. We finalized the acquisition accounting for Lucid during the current quarter. There were no material changes to our financial statements as a result of the finalization of this acquisition accounting. However, the acquisition accounting for IOTA is deemed provisional as we continue to gather information related to the identification and valuation of certain deferred tax items.

Accounting Changes and Error Corrections [Abstract]

New Accounting Pronouncements

Accounting Standards Adopted in Fiscal 2019

ASU 2017-01 -— Clarifying the Definition of a Business

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 obtained in an acquisition 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. We adopted ASU 2017-01 effective September 1, 2018 and applied the guidance prospectively. The provisions of ASU 2017-01 did not have a material effect on our financial condition, results of operations, or cash flows.

ASU 2016-15 — Statement of Cash Flows

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. These cash flows include 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. We adopted ASU 2016-15 effective September 1, 2018 and applied the changes retrospectively. We maintain life insurance policies on certain former employees primarily to satisfy obligations under certain deferred compensation plans. As required by the standard, proceeds from these policies are now classified as cash inflows from investing activities. We received $0.8 million and $0.7 million from corporate-owned

life insurance policies during the six months ended February 28, 2019 and 2018, respectively. As such, cash flows from operations for the six months ended February 28, 2018 decreased $0.7 million, with a corresponding increase to cash flows from investing activities, compared to amounts previously reported. The remaining provisions of ASU 2016-15 do not apply to us for the periods presented.

ASU 2017-07 — Presentation of Net Periodic Pension Cost

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 changes the presentation of net periodic pension cost related to employer sponsored defined benefit plans and other postretirement benefits. Service cost is now 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 pension cost are presented separately outside of operating income. Additionally, only service costs may be capitalized in assets. We adopted ASU 2017-07 effective as of September 1, 2018. We applied the standard retrospectively for the presentation of the service cost component and the other components of net periodic pension cost within our income statements. As a practical expedient, we used amounts previously disclosed in the Pension and Defined Contribution Plans footnote of the Notes to Consolidated Financial Statements within our Form 10-K as the basis for retrospective application because amounts capitalized in inventory at a given point in time are de minimis and determining these amounts was impractical. Upon adoption of ASU 2017-07, our previously reported Operating profit for the three and six months ended February 28, 2018 increased $1.5 million and $3.1 million, respectively, with a corresponding increase to Miscellaneous expense, net. The provisions of ASU 2017-07 have no impact to our net income or earnings per share.

The impact of the provisions of ASU 2017-07 on the Consolidated Statement of Comprehensive Income for the three and six months ended February 28, 2018 are as follows (in millions):



	Three Months Ended February 28, 2018							Six Months Ended February 28, 2018

Miscellaneous expense, net	2.8		1.3		1.5			4.0		0.9		3.1

ASC 606 — Revenue from Contracts with Customers

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which replaced the 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 those judgments.

We adopted ASC 606 effective September 1, 2018 using the modified retrospective method and recognized a cumulative effect of applying ASC 606 of $13.0 million in Retained earnings on the Consolidated Balance Sheet as of this date. We applied the standard to all contracts as of the transition date. Information for prior years presented has not been restated and continues to reflect the authoritative accounting standards in effect for those periods.

Adjustments related to the adoption of ASC 606 include additional deferrals of revenue recognition for service-type warranties and the gross presentation of right of return assets and refund liabilities for sales with a right of return. The effects of the adoption of ASC 606 on our Consolidated Statement of Comprehensive Income for the three and six months ended February 28, 2019, and the Consolidated Balance Sheet as of February 28, 2019 are as follows (in millions except per share amounts):

Accounting Standards Yet to Be Adopted

In August 2018, the FASB issued ASU No. 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (“ASU 2018-15”), which will require customers to apply internal-use software guidance to determine the implementation costs that are able to be capitalized. Capitalized implementation costs will be required to be amortized over the term of the arrangement, beginning when the cloud computing arrangement is ready for its intended use. ASU 2018-15 is effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2019. The standard allows changes to be applied either retrospectively or prospectively. We will adopt the standard as required in fiscal 2021. The provisions of ASU 2018-15 are not expected to have a material effect on our financial condition, results of operations, or cash flows.

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires an entity to assess impairment of its financial instruments based on its estimate of expected credit losses. The provisions of ASU 2016-13 are effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2019. Entities are required to apply these changes through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. We will adopt the amendments as required in fiscal 2021. The provisions of ASU 2016-13 are not expected to have a material effect on our financial condition, results of operations, or cash flows.

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. Since the issuance of ASU 2016-02, the FASB released several amendments to improve and clarify the implementation guidance, as well as to change the allowable adoption methods. These standards have been collectively codified within ASC 842, Leases (“ASC 842”). The standard allows entities to present the effects of the accounting change as either a cumulative adjustment as of the beginning of the earliest period

presented or as of the date of adoption. We have an implementation team tasked with reviewing our lease obligations and determining the impact of the new standard to our financial statements. The team is also tasked with identifying appropriate changes to our business processes, systems, and controls to support recognition and disclosure under the new standard. Currently, the implementation team has completed its review of outstanding property leases, which account for a substantial portion of our outstanding lease obligations. The team is in the process of reviewing and analyzing equipment leases, information technology contracts, and other contracts that may have ASC 842 impacts. At this time, we cannot reasonably estimate the impact of adopting the standard. The implementation team reports its 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. We will adopt the standard as required on September 1, 2019.

All other newly issued accounting pronouncements not yet effective have been deemed either immaterial or not applicable.

Revenue Recognition

Revenue from Contract with Customer [Abstract]

Revenue Recognition

We recognize revenue when we transfer control of goods and services to our customers. Revenue is measured as the amount of consideration we expect to receive in exchange for goods and services and is recognized net of allowances for rebates, sales incentives, product returns, and discounts to customers. Sales and use taxes collected on behalf of governmental authorities are excluded from revenues. Payment is generally due and received within 60 days from the point of sale or prior to the transfer of control of certain goods and services. No payment terms extend beyond one year, and we apply the practical expedient within ASC 606 to conclude that no significant financing terms exist within our contracts with customers. Allowances for cash discounts to customers are estimated using the expected value method based on historical experience and are recorded as a reduction to sales. Our standard terms and conditions of sale allow for the return of certain products within four months of the date of shipment. We also provide for limited product return rights to certain distributors and other customers, primarily for slow moving or damaged items subject to certain defined criteria. The limited product return rights generally allow customers to return resalable products purchased within a specified time period and subject to certain limitations, including, at times, when accompanied by a replacement order of equal or greater value. At the time revenue is recognized, we record a refund liability for the expected value of future returns primarily based on historical experience, specific notification of pending returns, or based on contractual terms with the respective customers. 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 adverse impact on our operating results in future periods.

Total refund liabilities recorded under ASC 606 related to rights of return, cash discounts, and other miscellaneous credits to customers were $36.9 million and $41.2 million as of February 28, 2019 and September 1, 2018, respectively, and are reflected within Other accrued liabilities on the Consolidated Balance Sheets. Additionally, we record right of return assets for products expected to be returned to our distribution centers, which are included within Prepayments and other current assets on the Consolidated Balance Sheets. Such assets totaled $15.2 million and $16.4 million as of February 28, 2019 and September 1, 2018, respectively.

We also maintain one-time or ongoing marketing and trade-promotion programs with certain customers that require us to estimate and accrue the expected costs of such programs. These arrangements include cooperative marketing programs, merchandising of our products, introductory marketing funds for new products, and other trade-promotion activities conducted by the customer. Costs associated with these programs are generally estimated based on the most likely amount expected to be settled based on the context of the individual contract and are reflected within the Consolidated Statements of Comprehensive Income in accordance with ASC 606, which in most instances requires such costs to be recorded as reductions of revenue. The refund liabilities associated with these programs totaled $32.9 million and $43.9 million as of February 28, 2019 and September 1, 2018, respectively, and are reflected within Other accrued liabilities on the Consolidated Balance Sheets.

Costs to obtain and fulfill contracts, such as sales commissions and shipping and handling activities, are short-term in nature and are expensed as incurred.

Nature of Goods and Services

Products

Approximately 94% of revenue is generated from short-term contracts with our customers to deliver tangible goods such as luminaires, lighting controllers, controllers for various building systems, power supplies, prismatic skylights, and drivers. We record revenue from these contracts when the customer obtains control of those goods. For sales designated free on board shipping point, control is transferred at the time of shipment. For sales designated free on board destination, customers take control when a product is delivered to the customer’s delivery site.

We collect fees associated with training, installation, and technical support services, primarily related to the set up of our lighting solutions. We recognize revenue for these one-time services at the time the service is performed. We also sell certain service-type warranties that extend coverages for products beyond their base warranties. We account for service-type warranties as distinct performance obligations and recognize revenue for these contracts ratably over the life of the additional warranty period. Claims related to service-type warranties are expensed as incurred.

Software

Software sales include licenses for software, data usage fees, and software as a service arrangements, which generally extend for one year or less. We recognize revenue for software based on the contractual rights provided to a customer, which typically results in the recognition of revenue ratably over the contractual service period.

Shipping and Handling Activities

We account for all shipping and handling activities as activities to fulfill the promise to transfer products to our customers. As such, we do not consider shipping and handling activities to be separate performance obligations, and we expense these costs as incurred.

Contracts with Multiple Performance Obligations

A small portion (approximately 6%) of our revenue is derived from the combination of any or all of products, professional services, and software licenses. Significant judgment may be required to determine which performance obligations are distinct and should be accounted for separately. We allocate the expected consideration to be collected to each distinct performance obligation based on its standalone selling price. Standalone selling price is generally determined using a cost plus margin valuation when no observable input is available. The amount of consideration allocated to each performance obligation is recognized as revenue in accordance with the timing for products, professional services, and software as described above.

Contract Balances

Our rights related to collections from customers are unconditional and are reflected within Accounts receivable on the Consolidated Balance Sheets. We do not have any other significant contract assets. Contract liabilities arise when we receive cash or an unconditional right to collect cash prior to the transfer of control of goods or services.

The amount of transaction price from contracts with customers allocated to our contract liabilities as of February 28, 2019 and September 1, 2018 consists of the following (in millions):



	February 28, 2019		September 1, 2018
Current deferred revenues	$	4.4	$	4.8
Non-current deferred revenues	40.3		35.0

Current deferred revenues primarily consist of software licenses, and to a lesser extent professional service and sales-type warranty fees collected prior to performing the related service. Current deferred revenues are included within Other current liabilities on the Consolidated Balance Sheets. These services are expected to be performed within one year. Non-current deferred revenues primarily consist of long-term service-type warranties, which are typically recognized ratably as revenue between five and ten years from the date of sale, and are included within Other long-

term liabilities on the Consolidated Balance Sheets. Revenue recognized from beginning balances of contract liabilities during the six months ended February 28, 2019 totaled $3.1 million.

Unsatisfied performance obligations that do not represent contract liabilities consist primarily of orders for physical goods that have not yet been shipped. This backlog of orders at any given time is affected by various factors, including seasonality, cancellations, sales promotions, production cycle times, and the timing of receipt and shipment of orders, which are usually shipped within a few weeks of order receipt. Accordingly, a comparison of backlog orders from period to period is not necessarily meaningful and may not be indicative of future shipments.

Disaggregated Revenues

Our lighting and building management solutions are sold primarily through independent sales agents who cover specific geographic areas and market channels, by internal sales representatives, through consumer retail channels, and directly to large corporate accounts. The following table shows revenue from contracts with customers by sales channel for the three and six months ended February 28, 2019 (in millions):

Fair Value Measurements

6 Months Ended

Feb. 28, 2019

Fair Value Disclosures [Abstract]

Fair Value Measurements

We determine 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).

Our cash and cash equivalents (Level 1), which are required to be carried at fair value and measured on a recurring basis, were $232.0 million and $129.1 million as of February 28, 2019 and August 31, 2018, respectively.

We utilize valuation methodologies to determine the fair values of our 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.

We 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 our financial instruments were as follows at February 28, 2019 and August 31, 2018 (in millions):



	February 28, 2019				August 31, 2018
	Carrying Value		Fair Value		Carrying Value		Fair Value
Senior unsecured public notes, net of unamortized discount and deferred costs	$	349.7	$	357.0	$	349.5	$	361.7
Industrial revenue bond	4.0		4.0		4.0		4.0
Bank loans	3.0		3.1		3.3		3.3

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, we estimate that the face amount of the bond approximates fair value as of February 28, 2019 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 us. 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 our 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 Disclosure [Abstract]

Goodwill and Intangible Assets

Through multiple acquisitions, we 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.

We recorded amortization expense of $7.7 million and $6.7 million during the three months ended February 28, 2019 and 2018, respectively, and $15.4 million and $13.3 million during the six months ended February 28, 2019 and 2018, respectively. Amortization expense is generally recorded on a straight-line basis and is expected to be approximately $30.8 million in fiscal 2019, $30.8 million in fiscal 2020, $28.0 million in fiscal 2021, $27.0 million in fiscal 2022, and $25.9 million in fiscal 2023.

The changes in the carrying amount of goodwill during the six months ended February 28, 2019 and 2018 are summarized below (in millions):

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, 2019 and 2018 (in millions, except per share data):



	Three Months Ended				Six Months Ended

Debt Disclosure [Abstract]

Debt and Lines of Credit

Lines of Credit

On June 29, 2018, we entered into a credit agreement (“Credit Agreement”) with a syndicate of banks that provides us with a $400.0 million five-year unsecured revolving credit facility (“Revolving Credit Facility”) and a $400.0 million unsecured delayed draw term loan facility (“Term Loan Facility”). We had no borrowings outstanding under the current Revolving Credit Facility or Term Loan Facility as of February 28, 2019. Additionally, we had no borrowings outstanding under our previous credit facility as of August 31, 2018.

Generally, amounts outstanding under the Revolving Credit Facility allow for borrowings to bear interest at either the Eurocurrency Rate or the base rate at our option, plus an applicable margin. 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 Interbank Offered Rate (“LIBOR”) or screen rate for the applicable currency plus an applicable margin. The Eurocurrency applicable margin is based on our leverage ratio, as defined in the Credit Agreement, with such margin ranging from 1.000% to 1.375%. Base rate advances bear interest at an alternate base rate plus an applicable margin. The base rate applicable margin is based on our leverage ratio, as defined in the Credit Agreement, with such margin ranging from 0.000% to 0.375%. The Term Loan Facility allows for borrowings to be drawn over a one-year period ending June 29, 2019, utilizing up to four separate installments, which are U.S. dollar denominated. Borrowings under the Term Loan Facility will amortize in equal quarterly installments of 2.5% per year in year one, 2.5% per year in year two, 5.0% per year in year three, 5.0% per year in year four, and 7.5% per year in year five. Any remaining borrowings under the Term Loan Facility are due and payable in full on June 29, 2023. The Term Loan Facility allows for borrowings to bear interest at either a Eurocurrency Rate or the base rate, at our option, in each case plus an applicable margin. 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 LIBOR or screen rate for the applicable currency plus an applicable margin. The Eurocurrency applicable margin is based on our leverage ratio, as defined in the Credit Agreement, with such margin ranging from 0.875% to 1.250%. Base Rate advances bear interest at an alternate base rate plus an applicable margin. The base rate applicable margin is based on our leverage ratio, as defined in the Credit Agreement, with such margin ranging from 0.0% to 0.25%.

We are required to pay certain fees in connection with the Credit Agreement, including administrative service fees and annual facility fees. The annual facility fee is payable quarterly, in arrears, and is determined by our leverage ratio as defined in the Credit Agreement. The facility fee ranges from 0.125% to 0.25% of the aggregate $800.0 million commitment of the lenders under the Credit Agreement. The Credit Agreement contains financial covenants, including a minimum interest expense coverage ratio (“Minimum Interest Expense Coverage Ratio”) and a leverage ratio (“Maximum Leverage Ratio”) of total indebtedness to earnings before interest, tax, depreciation, and amortization (“EBITDA”), as such terms are defined in the Credit Agreement. These ratios are computed at the end of each fiscal quarter for the most recent 12-month period. The Credit Agreement generally allows for a Minimum Interest Expense Coverage Ratio of 2.50 and a Maximum Leverage Ratio of 3.50, subject to certain conditions, as such terms are defined in the Credit Agreement.

We were in compliance with all financial covenants under the Credit Agreement as of February 28, 2019. At February 28, 2019, we had additional borrowing capacity under the Credit Agreement of $794.7 million under the most restrictive covenant in effect at the time, which represents the full amount of the Revolving Credit Facility and the Term Loan Facility less the outstanding letters of credit of $5.3 million issued under the Revolving Credit Facility. As of February 28, 2019, we had outstanding letters of credit totaling $9.5 million, primarily for securing collateral requirements under our casualty insurance programs and for providing credit support for our industrial revenue bond (not an outstanding amount under the Revolving Credit Facility).

Long-term Debt

At February 28, 2019, we 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”). Although the Unsecured Notes will mature within one year from February 28, 2019, we have the ability and intent to refinance these borrowings using availability under our Term Loan Facility, subject to satisfying the applicable conditions precedent. Currently, we plan to refinance the Unsecured Notes in full with borrowings under the Term Loan Facility, of which $343.3 million of the current carrying value would be due more than one year from the refinancing date. As such, this amount is reflected within Long-term debt on the Consolidated Balance Sheets as of February 28, 2019. We also had $4.0 million of tax-exempt industrial revenue bonds that are scheduled to mature in 2021 and $3.0 million outstanding under fixed-rate bank loans outstanding at February 28, 2019. Further discussion of our long-term debt is included within the Debt and Lines of Credit footnote of the Notes to Consolidated Financial Statements within our 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, 2019 and 2018 (in millions):

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

In the normal course of business, we are 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. We establish reserves when the associated costs related to uncertainties or guarantees become probable and can be reasonably estimated. For the period ended February 28, 2019, no material changes have occurred in our 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 our Form 10-K.

Product Warranty and Recall Costs

Our products generally have a standard warranty term of five years that assure our products comply with agreed upon specifications. We record 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. However, there can be no assurance that future warranty or recall costs will not exceed historical amounts or that new technology products 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 our results of operations and cash flows.

Reserves for these 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, 2019 and 2018 are summarized as follows (in millions):

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 our officers on behalf of all persons who purchased or otherwise acquired our 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 our stock between October 15, 2015 and April 3, 2017. The cases were transferred on April 30, 2018, to the United States District Court for the Northern District of Georgia and subsequently were consolidated as In re Acuity Brands, Inc. Securities Litigation, Civil Action No. 1:18-cv-02140-MHC (N.D. Ga.). On October 5, 2018, the court appointed lead plaintiff filed a consolidated amended class action complaint (the “Consolidated Complaint”), which supersedes the initial complaints. The Consolidated Complaint is brought on behalf of all persons who purchased our common stock between October 7, 2015 and April 3, 2017 and alleges that the Company and certain of our current officers and one former executive 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 our ability to achieve profitable sales growth. The plaintiffs seek class certification, unspecified monetary damages, costs, and attorneys’ fees. We dispute the allegations and intend to vigorously defend against the claims in the complaints. We have filed a motion to dismiss the Consolidated Complaint. 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, we are 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. We maintain Director and Officer insurance policies that may cover any liability arising out of this litigation up to the policies’ limits, subject to a self-insured retention and other terms and conditions.

Litigation

We are 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 our financial condition, results of operations, or cash flows. 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 our financial condition, results of operations, or cash flows in future periods. We establish 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, we cannot make a meaningful estimate of actual costs to be incurred that could possibly be higher or lower than the amounts reserved.

Trade Compliance Matters

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

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Share-based Payments

We account for share-based payments through the measurement and recognition of compensation expense for share-based payment awards made to employees and directors, including stock options and restricted shares (all part of our equity incentive plan), and share units representing certain deferrals into our director deferred compensation plan or our supplemental deferred savings plan.

The following table presents share-based payment expense and new shares issued upon exercise of stock options for the three and six months ended February 28, 2019 and 2018 (in millions, except shares):

Retirement Benefits [Abstract]

Pension Plans

We have several pension plans, both qualified and non-qualified, covering certain hourly and salaried employees. Benefits paid under these plans are based generally on employees’ years of service and/or compensation during the final years of employment. We make annual contributions to the plans to the extent indicated by actuarial valuations and statutory requirements. Plan assets are invested primarily in equity and fixed income securities.

Service cost of net periodic pension cost is allocated between Cost of products sold and Selling, distribution, and administrative expenses in the Consolidated Statements of Comprehensive Income based on the nature of the employee's services. All other components of net periodic pension cost are included within Miscellaneous expense, net in the Consolidated Statements of Comprehensive Income. Net periodic pension cost during the three and six months ended February 28, 2019 and 2018 included the following components before tax (in millions):

Special Charge

Restructuring and Related Activities [Abstract]

Special Charge

During fiscal 2019, we recognized pre-tax special charges of $1.4 million. These charges primarily related to move costs associated with the previously announced transfer of activities from a planned facility closure. During fiscal 2018, we recognized special charges consisting primarily of severance and employee-related benefit costs for the elimination of certain operations and positions following a realignment of our operating structure, including positions within various selling, distribution, and administrative (“SD&A”) departments. Further details regarding our special charges are included within the Special Charge footnote of the Notes to Consolidated Financial Statements within our Form 10-K.

Costs reflected within Special charge on the Consolidated Statements of Comprehensive Income for the three and six months ended February 28, 2019 and 2018 are summarized as follows (in millions):

Income Taxes	Feb. 28, 2019
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes During the second quarter of fiscal 2019, we finalized our accounting for the tax effects of the Tax Cuts and Jobs Act (“TCJA”) in accordance with Staff Accounting Bulletin No. 118 (“SAB 118”). As a result, we recorded a net tax benefit of $0.9 million related to TCJA impacts including, but not limited to, our one-time transition tax, deferred income taxes, and executive compensation. Previously, we asserted that all undistributed earnings and original investments in foreign subsidiaries were indefinitely reinvested and, therefore, had not recorded any deferred taxes related to any outside basis differences associated with our foreign subsidiaries. As of February 28, 2019, the estimated undistributed earnings from foreign subsidiaries was $78.3 million. A significant portion of these earnings was subject to U.S. federal taxation in fiscal 2018 as part of the one-time transition tax. We are no longer asserting indefinite reinvestment on the portion of our unremitted earnings that were previously subject to U.S. federal taxation with the one-time transition tax. Accordingly, we recognized a deferred income tax liability of $0.6 million for certain foreign withholding taxes and U.S. state taxes during the current quarter. With respect to unremitted earnings and original investments in foreign subsidiaries where we are continuing to assert indefinite reinvestment, any future remittances could be subject to additional foreign withholding taxes, U.S. state taxes, and certain tax impacts relating to foreign currency exchange effects. It is not practicable to estimate the amount of any unrecognized tax effects on these reinvested earnings and original investments in foreign subsidiaries. We have elected to account for the tax on Global Intangible Low-Taxed Income (“GILTI”) as a period cost and, therefore, do not record deferred taxes related to GILTI on our foreign subsidiaries. Further details regarding the effects of the TCJA are included within the Income Taxes footnote of the Notes to Consolidated Financial Statements within our Form 10-K.

Supplemental Guarantor Condensed Consolidating Financial Statements

Condensed Financial Information 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 Unsecured 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 Unsecured Notes and the initial purchasers of the Unsecured Notes, ABL and the guarantors to the Notes filed a registration statement with the SEC for an offer to exchange the Unsecured Notes for an issue of SEC-registered notes with identical terms. Due to the filing of the registration statement and offer to exchange, we 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, we have included the accompanying Condensed Consolidating Financial Statements in accordance with Rule 3-10(d) of SEC Regulation S-X since the Unsecured 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.CONDENSED CONSOLIDATING BALANCE SHEETS

Use of Estimates

Use of EstimatesThe 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.
