Basis of Presentation We have 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, Inc. 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 November 30, 2024, our consolidated comprehensive income for the three months ended November 30, 2024 and November 30, 2023, and our consolidated cash flows for the three months ended November 30, 2024 and November 30, 2023. 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 as of and for the three years in the period ended August 31, 2024 and notes thereto included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on October 28, 2024 (“Form 10-K”). Our business exhibits some seasonality, with net sales being affected by weather and seasonal demand on construction and installation programs, particularly during the winter months, as well as the annual budget cycles of major customers. Historically, with certain exceptions, we have experienced our highest sales in the last two quarters of each fiscal year due to these factors.

Significant Accounting Policies

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 We may reclassify certain prior period amounts to conform to the current year presentation. No material reclassifications occurred during the current period.

New Accounting Pronouncements	New Accounting Pronouncements Accounting Standards Yet to Be Adopted Accounting Standards Update ( “ ASU ” ) 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Topic 220): Disaggregation of Income Statement Expenses ( “ ASU 2024-03 ” ) In November 2024, the Financial Accounting Standards Board (“FASB”) issued ASU 2024-03, which requires public entities to disaggregate specific types of expenses, including disclosures for purchases of inventory, employee compensation, depreciation, and intangible asset amortization, as well as selling expenses. Annual disclosures are required for fiscal years beginning after December 15, 2026, or our fiscal 2028. Interim disclosures are required for periods within fiscal years beginning after December 15, 2027, or our fiscal 2029. Prospective application is required, and retrospective application is permitted. Early adoption is permitted. We are currently assessing the impact of the requirements on our consolidated financial statements and disclosures. ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ( “ ASU 2023-09 ” ) In December 2023, the FASB issued ASU 2023-09, which expands income tax disclosure requirements to include additional information related to the rate reconciliation of our effective tax rates to statutory rates as well as additional disaggregation of taxes paid. The amendments in the ASU also remove disclosures related to certain unrecognized tax benefits and deferred taxes. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, or our fiscal 2026. The amendments may be applied prospectively or retrospectively, and early adoption is permitted. We are currently assessing the impact of the requirements on our consolidated financial statements and disclosures. ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ( “ ASU 2023-07 ” ) In November 2023, the FASB issued ASU 2023-07, which expands reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in the ASU require that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to an entity's chief operating decision maker (“CODM”), a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. Annual disclosures are required for fiscal years beginning after December 15, 2023 or our fiscal 2025. Interim disclosures are required for periods within fiscal years beginning after December 15, 2024, or our fiscal 2026. Retrospective application is required for all prior periods presented, and early adoption is permitted. We are currently assessing the impact of the requirements on our consolidated financial statements and disclosures. All other newly issued accounting pronouncements not yet effective have been deemed either immaterial or not applicable.

Fair Value Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements We determine fair value measurements based on the assumptions a market participant would use in pricing an asset or liability. ASC Topic 820, Fair Value Measurement (“ASC 820”), establishes a three-level hierarchy that distinguishes 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). 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. 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. We may from time to time be required to remeasure the carrying value of certain assets and liabilities to fair value on a nonrecurring basis. Such adjustments typically arise if we determine that certain of our assets are impaired. Financial Instruments Recorded at Fair Value The following table summarizes balances and the fair value hierarchy level of our financial instruments recorded at fair value on a recurring basis as of the dates presented (in millions): November 30, 2024 August 31, 2024 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Cash and cash equivalents $ 935.6 $ — $ — $ 935.6 $ 845.8 $ — $ — $ 845.8 Other financial instruments — — — — — — — — Assets in fair value hierarchy 935.6 — — 935.6 845.8 — — 845.8 Other investments (1) 5.1 6.7 Total assets at fair value $ 935.6 $ — $ — $ 940.7 $ 845.8 $ — $ — $ 852.5 ____________________________________ (1) Includes strategic investments in privately-held entities over which we do not exercise significant influence or control and without readily determinable fair values. Amounts are recorded at cost less any impairment adjusted for observable price changes, if any. Disclosures of Fair Value of Financial Instruments Disclosures of fair value information about financial instruments, 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 Topic 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, such as the discount rate and estimates of future cash flows. Fair value for our outstanding debt obligations is estimated based on discounted future cash flows using rates currently available for debt of similar terms and maturity (Level 2). Our 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. The estimated fair value of our senior unsecured public notes was $432.5 million and $429.7 million as of November 30, 2024 and August 31, 2024, respectively. We had no short-term borrowings outstanding under our revolving credit facility as of November 30, 2024 and August 31, 2024. Such borrowings, if any, are variable-rate instruments that reset on a frequent short-term basis; therefore, we estimate that any outstanding carrying values of these instruments, which are equal to their face amounts, approximate their fair values. See Debt and Lines of Credit footnote of the Notes to Consolidated Financial Statements for further details on our outstanding borrowings. 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.

Inventories are stated on a first-in, first-out basis at the lower of cost and net realizable value and consist of the following as of the dates presented (in millions): November 30, 2024 August 31, 2024 Raw materials, supplies, and work in process (1) $ 227.5 $ 222.1 Finished goods 190.2 191.1 Inventories excluding reserves 417.7 413.2 Less: Reserves (26.6) (25.6) Total inventories $ 391.1 $ 387.6 _______________________________________ (1) Due to the immaterial amount of estimated work in process and the short lead times for the conversion of raw materials to finished goods, we do not believe the segregation of raw materials and work in process is meaningful information. We review inventory quantities on hand and record a provision for excess and obsolete inventory primarily based on estimated future demand and current market conditions. A significant change in customer demand and/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.

Debt Disclosure [Abstract]
Debt and Lines of Credit	Debt and Lines of Credit Long-term Debt On November 10, 2020, Acuity Brands Lighting, Inc., a wholly-owned operating subsidiary of Acuity Brands, Inc., issued $500.0 million aggregate principal amount of 2.150% senior unsecured notes due December 15, 2030 (the “Unsecured Notes”) at a price equal to 99.737% of their face value. Interest on the Unsecured Notes is paid semi-annually in arrears on June 15 and December 15 of each year. At issuance we recorded $4.8 million of deferred issuance costs related to the Unsecured Notes as a direct deduction from the face amount of the Unsecured Notes. These issuance costs are amortized over the 10-year term of the Unsecured Notes. The Unsecured Notes are fully and unconditionally guaranteed on a senior unsecured basis by Acuity Brands, Inc. and ABL IP Holding LLC, a wholly-owned subsidiary of Acuity Brands, Inc. Lines of Credit On June 30, 2022, we entered into a credit agreement (the “Credit Agreement”) with a syndicate of banks that provides us with a $600.0 million five-year unsecured revolving credit facility (the “Revolving Credit Facility”) with the ability to request an additional $400.0 million of borrowing capacity. We had no short-term borrowings outstanding under the Revolving Credit Facility at November 30, 2024 and August 31, 2024. On November 25, 2024, we entered into an amendment to the Credit Agreement that, among other things, provides for a delayed draw term loan facility of up to $600.0 million (the “Term Loan Facility”), which may be drawn in a single borrowing at any time through May 25, 2025, subject to certain conditions. The Credit Agreement permits the proceeds of the Term Loan Facility to be used for general corporate purposes, including working capital, permitted acquisitions, and repurchases of capital stock. The Term Loan Facility will mature on June 30, 2027, which is the maturity date of the revolving loans and commitments under the existing Credit Agreement. Borrowings under the Term Loan Facility bear interest at an adjusted term Secured Overnight Financing Rate (“SOFR”), adjusted daily simple SOFR rate, or base rate, at the Company’s option, plus an applicable margin. The applicable margin is based on, at our option, the Company’s leverage ratio or ratings level, each as defined in the Credit Agreement, and ranges from 0.875% to 1.375% (for SOFR-based loans) and from 0.0% to 0.375% (for base rate loans). Undrawn commitments under the Term Loan Facility will accrue a commitment fee from and after February 24, 2025 at a per annum rate ranging from 0.075% to 0.175%, depending on, at our option, the Company’s leverage ratio or ratings level, each as defined in the Credit Agreement. The covenants and events of default that apply to the revolving loans and commitments under the Credit Agreement also apply to the Term Loan Facility, and borrowings under the Term Loan Facility are guaranteed by the Company and the subsidiaries of the Company that guarantee the revolving loans and commitments. We had no borrowings outstanding under the Term Loan Facility at November 30, 2024. We were in compliance with all financial covenants under the Credit Agreement as of the periods presented. At November 30, 2024, we had additional borrowing capacity under the Credit Agreement of $1.2 billion 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 outstanding letters of credit of $3.5 million issued under the Revolving Credit Facility, primarily for securing collateral requirements under our casualty insurance premiums. None of our existing debt instruments include provisions that would require an acceleration of repayments based solely on changes in our credit ratings. Borrowings and repayments on our Revolving Credit Facility with terms of three months or less are reported on a net basis on our Consolidated Statements of Cash Flows .

Commitments and Contingencies	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 estimated liabilities and claims, legal and contractual issues, environmental laws and regulations, guarantees, and indemnities. We establish estimated liabilities when the associated costs related to uncertainties or guarantees become probable and can be reasonably estimated. For the period ended November 30, 2024, no material changes have occurred in our estimated liabilities 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 Costs Our products generally have a standard warranty term of five years that assure our products comply with agreed upon specifications. We record an accrual for the estimated amount of future warranty costs in accordance with ASC Topic 450, Contingencies (“ASC 450”) when the related revenue is recognized and when costs are deemed to be probable and can be reasonably estimated. Liabilities related to product warranty costs are subject to uncertainty because they require estimates of future costs. Estimated future warranty costs are primarily based on historical experience, including the number and costs of identified warranty claims as well as the period of time between the shipment of products and our settlement of related claims. Any estimated or actual loss recoveries that offset our costs and payments are reflected as assets and included within Other current assets or Other long-term assets based on the timing of receipt of recovery. Recoveries are recorded net of allowances for credit losses. Although we assume that historical experience will continue to be the best indicator of future warranty costs, we cannot assure that future warranty costs will not exceed historical amounts, and/or loss recoveries will not be fully collectible. If actual future warranty costs exceed recorded amounts, or recoveries are no longer collectible, adjustments to our accruals and/or receivables may be warranted, which could have a material adverse impact on our results of operations and cash flows. Estimated liabilities for product warranty costs are included in Other accrued liabilities or Other long-term liabilities on the Consolidated Balance Sheets based upon when we expect to settle the incurred warranty. The following table summarizes changes in the estimated liabilities for product warranty costs during the periods presented (in millions): Three Months Ended November 30, 2024 November 30, 2023 Beginning balance $ 37.5 $ 31.6 Product warranty costs (1) 6.3 12.4 Payments and other deductions (1) (9.3) (11.3) Ending balance $ 34.5 $ 32.7 _________________________ (1) Amounts exclude any estimated or actual loss recoveries. 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 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 estimated liabilities 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 accrued 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 accrued amounts.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue 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. We allocate the expected consideration to be collected to each distinct performance obligation identified in a sale based on its standalone selling price. Sales and use taxes collected on behalf of governmental authorities are excluded from revenues. Further details regarding revenue recognition are included within the Revenue Recognition footnote of the Notes to Consolidated Financial Statements within our Form 10-K. Contract Balances Our rights related to collections from customers are unconditional and are reflected within Accounts receivable on the Consolidated Balance Sheets at net realizable value. Further details regarding our method for developing our estimate of expected credit losses over the contractual term of our receivables are included within the Significant Accounting Policies footnote of the Notes to Consolidated Financial Statements within our Form 10-K. 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 consists of the following as of the dates presented (in millions): November 30, 2024 August 31, 2024 Current deferred revenues $ 17.0 $ 17.4 Non-current deferred revenues 39.6 41.5 Current deferred revenues primarily consist of service-type warranty and professional service fees collected prior to performing the related service as well as software licenses. Current deferred revenues are included within Other current liabilities on the Consolidated Balance Sheets . These services are expected to be performed within one year. Revenue recognized from beginning balances of contract liabilities during the three months ended November 30, 2024 totaled $5.4 million. 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. Unsatisfied performance obligations that do not represent contract liabilities are expected to be satisfied within one year from November 30, 2024 and consist primarily of orders for physical goods that have not yet been shipped. Disaggregated Revenues Our Acuity Brands Lighting segment's products are sold primarily through independent sales agents who cover specific geographic areas and market channels, by internal sales representatives, through consumer retail channels, directly to large corporate accounts, and through other distribution methods, including directly to OEM customers. Acuity Intelligent Spaces sells predominantly to system integrators.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share 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, unvested share-based payment awards were vested, and other distributions related to deferred stock agreements were incurred. Common stock equivalents are calculated using the treasury stock method. The dilutive effects of share-based payment awards subject to market and/or performance conditions that were not met during the period are excluded from the computation of diluted earnings per share. The following table calculates basic earnings per common share and diluted earnings per common share for the periods presented (in millions, except per share data): Three Months Ended November 30, 2024 November 30, 2023 Net income $ 106.7 $ 100.6 Basic weighted average shares outstanding 30.930 31.005 Common stock equivalents 0.869 0.360 Diluted weighted average shares outstanding 31.799 31.365 Basic earnings per share (1) $ 3.45 $ 3.25 Diluted earnings per share (1) $ 3.35 $ 3.21 _______________________________________ (1) Earnings per share is calculated using unrounded numbers. Amounts in the table may not recalculate exactly due to rounding. Stock options, performance stock awards, and restricted stock awards that were excluded from the diluted earnings per share calculation as the effect of inclusion would have been antidilutive were immaterial for three months ended November 30, 2024 and 2023. Further discussion of our share-based payment awards is included within the Common Stock and Related Matters and Share-based Payments footnotes of the Notes to Consolidated Financial Statements within our Form 10-K.

Basis of Presentation	Basis of Presentation We have 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, Inc. 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 November 30, 2024, our consolidated comprehensive income for the three months ended November 30, 2024 and November 30, 2023, and our consolidated cash flows for the three months ended November 30, 2024 and November 30, 2023. 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 as of and for the three years in the period ended August 31, 2024 and notes thereto included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on October 28, 2024 (“Form 10-K”). Our business exhibits some seasonality, with net sales being affected by weather and seasonal demand on construction and installation programs, particularly during the winter months, as well as the annual budget cycles of major customers. Historically, with certain exceptions, we have experienced our highest sales in the last two quarters of each fiscal year due to these factors.
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 We may reclassify certain prior period amounts to conform to the current year presentation. No material reclassifications occurred during the current period.
New Accounting Pronouncements	New Accounting Pronouncements Accounting Standards Yet to Be Adopted Accounting Standards Update ( “ ASU ” ) 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Topic 220): Disaggregation of Income Statement Expenses ( “ ASU 2024-03 ” ) In November 2024, the Financial Accounting Standards Board (“FASB”) issued ASU 2024-03, which requires public entities to disaggregate specific types of expenses, including disclosures for purchases of inventory, employee compensation, depreciation, and intangible asset amortization, as well as selling expenses. Annual disclosures are required for fiscal years beginning after December 15, 2026, or our fiscal 2028. Interim disclosures are required for periods within fiscal years beginning after December 15, 2027, or our fiscal 2029. Prospective application is required, and retrospective application is permitted. Early adoption is permitted. We are currently assessing the impact of the requirements on our consolidated financial statements and disclosures. ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ( “ ASU 2023-09 ” ) In December 2023, the FASB issued ASU 2023-09, which expands income tax disclosure requirements to include additional information related to the rate reconciliation of our effective tax rates to statutory rates as well as additional disaggregation of taxes paid. The amendments in the ASU also remove disclosures related to certain unrecognized tax benefits and deferred taxes. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, or our fiscal 2026. The amendments may be applied prospectively or retrospectively, and early adoption is permitted. We are currently assessing the impact of the requirements on our consolidated financial statements and disclosures. ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ( “ ASU 2023-07 ” ) In November 2023, the FASB issued ASU 2023-07, which expands reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in the ASU require that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to an entity's chief operating decision maker (“CODM”), a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. Annual disclosures are required for fiscal years beginning after December 15, 2023 or our fiscal 2025. Interim disclosures are required for periods within fiscal years beginning after December 15, 2024, or our fiscal 2026. Retrospective application is required for all prior periods presented, and early adoption is permitted. We are currently assessing the impact of the requirements on our consolidated financial statements and disclosures. All other newly issued accounting pronouncements not yet effective have been deemed either immaterial or not applicable.
Fair Value Measurement	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.
Fair Value Transfers	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. We may from time to time be required to remeasure the carrying value of certain assets and liabilities to fair value on a nonrecurring basis. Such adjustments typically arise if we determine that certain of our assets are impaired.
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. We allocate the expected consideration to be collected to each distinct performance obligation identified in a sale based on its standalone selling price. Sales and use taxes collected on behalf of governmental authorities are excluded from revenues. Further details regarding revenue recognition are included within the Revenue Recognition footnote of the Notes to Consolidated Financial Statements within our Form 10-K. Contract Balances Our rights related to collections from customers are unconditional and are reflected within Accounts receivable on the Consolidated Balance Sheets at net realizable value. Further details regarding our method for developing our estimate of expected credit losses over the contractual term of our receivables are included within the Significant Accounting Policies footnote of the Notes to Consolidated Financial Statements within our Form 10-K. Current deferred revenues primarily consist of service-type warranty and professional service fees collected prior to performing the related service as well as software licenses. Current deferred revenues are included within Other current liabilities on the Consolidated Balance Sheets . These services are expected to be performed within one year. Revenue recognized from beginning balances of contract liabilities during the three months ended November 30, 2024 totaled $5.4 million. 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 Disaggregated Revenues
