Accounting Policies [Abstract] |
Principles of Consolidation | The Consolidated Financial Statements include the accounts of Acuity Brands and its wholly-owned subsidiaries after elimination of intercompany transactions and accounts.
Revenue Recognition and Shipping and Handling Fees and Costs | We include shipping and handling fees billed to customers in Net sales in the Consolidated Statements of Comprehensive Income. Shipping and handling costs associated with inbound freight and freight between manufacturing facilities and distribution centers are generally recorded in Cost of products sold in the Consolidated Statements of Comprehensive Income. Other shipping and handling costs are included in Selling, distribution, and administrative expenses in the Consolidated Statements of Comprehensive Income 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, service-type warranties, and discounts to customers. Please refer to the Revenue Recognition footnote of the Notes to Consolidated Financial Statements for additional information.
Use of Estimates | The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates.
Cash and Cash Equivalents | Cash in excess of daily requirements is invested in time deposits and marketable securities and is included in the accompanying balance sheets at fair value. We consider time deposits and marketable securities with an original maturity of three months or less when purchased to be cash equivalents.
Accounts Receivable | We record accounts receivable at net realizable value. This value includes a reserve for doubtful accounts to reflect losses anticipated on accounts receivable balances. The allowance is based on historical write-offs, an analysis of past due accounts based on the contractual terms of the receivables, and the economic status of customers, if known. We believe that the allowance is sufficient to cover uncollectible amounts; however, there can be no assurance that unanticipated future business conditions of customers will not have a negative impact on our results of operations. Prior to the adoption of the new revenue accounting standard described in the New Accounting Pronouncements footnote, we recorded reserves for product returns, cash discounts, and other deductions due to customers as a reduction to our outstanding receivables.
Concentrations of Credit Risk | Concentrations of credit risk with respect to receivables, which are typically unsecured, are generally limited due to the wide variety of customers and markets using our lighting and building management solutions as well as their dispersion across many different geographic areas.
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.
Subsequent Events | We have evaluated subsequent events for recognition and disclosure for occurrences and transactions after the date of the consolidated financial statements as of August 31, 2019.
Inventories | Inventories include materials, direct labor, inbound freight, and related manufacturing overhead, are stated at the lower of cost (on a first-in, first-out or average cost basis) and net realizable value We review inventory quantities on hand and record a provision for excess or obsolete inventory primarily based on estimated future demand and current market conditions. A significant change in customer demand or market conditions could render certain inventory obsolete and could have a material adverse impact on our operating results in the period the change occurs.
Assets Held for Sale | In accordance with U.S. GAAP, we classify assets as held for sale upon the development of a plan for disposal and cease the depreciation and amortization of the assets at that date.
Goodwill and Other Intangibles | The impairment test for indefinite-lived trade names consists of comparing the fair value of a trade name with its carrying value. If the carrying amount exceeds the estimated fair value, an impairment loss would be recorded in the amount of the excess. We estimate the fair value of indefinite-lived trade names using a fair value model based on discounted future cash flows. Significant assumptions, including estimated future net sales, royalty rates, and discount rates, are used in the determination of estimated fair value for indefinite-lived trade names. 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. Significant estimates and assumptions were used to determine the initial fair value of these acquired intangible assets, including estimated future net sales, customer attrition rates, royalty rates, and discount rates. Certain of our intangible assets are attributable to foreign operations and are impacted by currency translation due to movements in foreign currency rates year over year. We test goodwill and indefinite-lived intangible assets for impairment on an annual basis or more frequently as facts and circumstances change, as required by ASC Topic 350, Intangibles — Goodwill and Other (“ASC 350”). ASC 350 allows for an optional qualitative analysis for goodwill to determine the likelihood of impairment. If the qualitative review results in a more likely than not probability of impairment, a quantitative analysis is required. The qualitative step may be bypassed entirely in favor of a quantitative test. The quantitative analysis identifies impairments by comparing the fair value of a reporting unit with its carrying value, including goodwill. The fair values can be determined based on a combination of valuation techniques including the expected present value of future cash flows, a market multiple approach, and a comparable transaction approach. If the fair value of a reporting unit exceeds its carrying value, goodwill is not considered impaired. Conversely, if the carrying value of a reporting unit exceeds its fair value, an impairment charge for the difference is recorded.
Share-Based Payments | We recognize compensation cost relating to share-based payment transactions in the financial statements based on the estimated grant date fair value of the equity or liability instrument issued. We account for stock options, restricted shares, and share units representing certain deferrals into the Nonemployee Director Deferred Compensation Plan (the “Director Plan”) or the Supplemental Deferred Savings Plan (“SDSP”) (both of which are discussed further in the Share-based Payments footnote) based on the grant-date fair value estimated under the current provisions of ASC Topic 718, Compensation — Stock Compensation (“ASC 718”).
Depreciation | Depreciation is determined principally on a straight-line basis using estimated useful lives of plant and equipment (10 to 40 years for buildings and related improvements and 3 to 15 years for machinery and equipment) for financial reporting purposes, while accelerated depreciation methods are used for income tax purposes. Leasehold improvements are amortized over the shorter of the life of the lease or the estimated useful life of the improvement.
Research and Development | Research and development (“R&D”) expense, which is expensed as incurred, consists of compensation, payroll taxes, employee benefits, materials, supplies, and other administrative costs. R&D does not include all new product development costs and is included in Selling, distribution, and administrative expenses in our Consolidated Statements of Comprehensive Income.
Advertising | Advertising costs are expensed as incurred and are included within Selling, distribution, and administrative expenses in our Consolidated Statements of Comprehensive Income.
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 line of credit borrowings, partially offset by interest income earned on cash and cash equivalents.
Miscellaneous Expense, Net | Miscellaneous expense, net, is comprised primarily of non-service related components of net periodic pension cost, gains or losses on foreign currency items, and other non-operating items.
Income Taxes | We are taxed at statutory corporate rates after adjusting income reported for financial statement purposes for certain items that are treated differently for income tax purposes. Deferred income tax expenses or benefits result from changes during the year in cumulative temporary differences between the tax basis and book basis of assets and liabilities.
Foreign Currency Translation | The functional currency for foreign operations is the local currency where the foreign operations are domiciled. The translation of foreign currencies into U.S. dollars is performed for balance sheet accounts using exchange rates in effect at the balance sheet dates and for revenue and expense accounts using a weighted average exchange rate each month during the year. The gains or losses resulting from the balance sheet translation are included in Foreign currency translation adjustments in the Consolidated Statements of Comprehensive Income and are excluded from net income.
Comprehensive Income | Comprehensive income represents a measure of all changes in equity that result from recognized transactions and other economic events other than transactions with owners in their capacity as owners. Other comprehensive income (loss) includes foreign currency translation and pension adjustments.
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, Business Combinations (Topic 805): 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 (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“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 proceeds of $0.8 million and $1.7 million from settlements of corporate-owned life insurance policies during the years ended August 31, 2019 and 2018, respectively, and received no cash from these policies during the year ended August 31, 2017. As such, cash flows from operations for the year ended August 31, 2018 decreased $1.7 million with a corresponding increase to cash flows from investing activities, compared to amounts previously reported. The remaining provisions of ASU 2016-15 did not impact our financial statements 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 fiscal 2018 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 years ended August 31, 2018 and 2017 increased $6.2 million and $8.7 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 Statements of Comprehensive Income for the years ended August 31, 2018 and 2017 are as follows (in millions):
| Year Ended August 31, 2018 |  | Year Ended August 31, 2017
| As Revised |  | Previously Reported |  | Higher (Lower) |  | As Revised |  | Previously Reported |  | Higher (Lower)
Cost of products sold | $ | 2,194.7 |  |  | $ | 2,193.3 |  |  | $ | 1.4 |  |  | $ | 2,024.0 |  |  | $ | 2,023.9 |  |  | $ | 0.1 |
Selling, distribution, and administrative expenses | 1,019.0 |  |  | 1,026.6 |  |  | (7.6 | ) |  | 942.3 |  |  | 951.1 |  |  | (8.8 | )
Miscellaneous expense, net | 1.4 |  |  | (4.8 | ) |  | 6.2 |  |  | 2.4 |  |  | (6.3 | ) |  | 8.7 |
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 retrospectively adjusted 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 year ended August 31, 2019 and the Consolidated Balance Sheet as of August 31, 2019 are as follows (in millions except per share amounts):
Consolidated Statement of Comprehensive Income |  | Year Ended August 31, 2019
|  | As Currently Reported |  | Without ASC 606 Adoption |  | Higher (Lower)
Net sales |  | $ | 3,672.7 |  |  | $ | 3,681.6 |  |  | $ | (8.9 | )
Cost of products sold |  | 2,193.0 |  |  | 2,197.1 |  |  | (4.1 | )
Selling, distribution, and administrative expenses |  | 1,015.0 |  |  | 1,014.6 |  |  | 0.4 |
Operating profit |  | 462.9 |  |  | 468.1 |  |  | (5.2 | )
Income tax expense |  | 94.5 |  |  | 95.7 |  |  | (1.2 | )
Net income |  | 330.4 |  |  | 334.4 |  |  | (4.0 | )
Basic earnings per share |  | $ | 8.32 |  |  | $ | 8.42 |  |  | $ | (0.10 | )
Diluted earnings per share |  | 8.29 |  |  | 8.39 |  |  | (0.10 | )
Consolidated Balance Sheet |  | August 31, 2019
|  | As Currently Reported |  | Without ASC 606 Adoption |  | Higher (Lower)
Accounts receivable, net |  | $ | 561.0 |  |  | 539.6 |  |  | $ | 21.4 |
Prepayments and other current assets |  | 79.0 |  |  | 65.1 |  |  | 13.9 |
Other accrued liabilities |  | 175.0 |  |  | 139.4 |  |  | 35.6 |
Deferred income tax liabilities |  | 92.7 |  |  | 98.0 |  |  | (5.3 | )
Other long-term liabilities |  | 110.7 |  |  | 88.7 |  |  | 22.0 |
Retained earnings |  | 2,295.8 |  |  | 2,312.8 |  |  | (17.0 | )
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 companies to apply internal-use software guidance to determine the implementation costs of these arrangements that can 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, Financial Instruments - Credit Losses (Topic 326): 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. The implementation team completed its review of our lease obligations outstanding at August 31, 2019 and is in the process of reviewing and finalizing transition adjustments to the balance sheet. 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. Based on our lease portfolio as of August 31, 2019, we preliminarily expect the adoption of ASC 842 to result in the recognition of operating lease liabilities between $63 million and $68 million. We expect the corresponding operating lease right of use assets to approximate the lease total liabilities less our deferred rent balance as of August 31, 2019. We do not expect ASC 842 to have a material impact on our consolidated statements of comprehensive income or cash flows. Further details regarding our undiscounted future lease payments as well as the timing of those payments are included within the Commitments and Contingencies footnote of the Notes to Consolidated Financial Statements within our Form 10-K. We will adopt ASC 842 as required effective September 1, 2019. All other newly issued accounting pronouncements not yet effective have been deemed either immaterial or not applicable.
