Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations and Accounting Policies	Nature of Operations and Accounting Policies Nature of Operations Thor Industries, Inc. was founded in 1980 and is the sole owner of operating subsidiaries (collectively, the “Company” or "Thor"), that, combined, represent the world's largest manufacturer of recreational vehicles (“RVs”). The Company manufactures a wide variety of RVs in the United States and Europe and sells those vehicles, as well as related parts and accessories, primarily to independent, non-franchise dealers throughout the United States, Canada and Europe. Unless the context requires or indicates otherwise, all references to “Thor,” the “Company,” “we,” “our” and “us” refer to Thor Industries, Inc. and its subsidiaries. The July 31, 2019 amounts are derived from the annual audited financial statements of Thor. The interim financial statements are unaudited. In the opinion of management, all adjustments (which consist of normal, recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows for the interim periods presented have been made. These financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2019. Due to seasonality within the recreational vehicle industry, among other factors, annualizing the results of operations for the three months ended October 31, 2019 would not necessarily be indicative of the results expected for the full fiscal year. Recently Adopted Accounting Standards In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842),” and has subsequently issued ASU's 2018-10, "Codification Improvements (Topic 842)," and 2018-11, "Targeted Improvements (Topic 842)" (collectively the "New Leasing Standard"), which provide guidance on the recognition, measurement, presentation, and disclosure of leases. The New Leasing Standard requires the recognition of lease assets and lease liabilities by lessees for all leases with terms greater than 12 months. The principal difference from prior guidance is that the lease assets and lease liabilities arising from operating leases are now recognized on the Condensed Consolidated Balance Sheet. The New Leasing Standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. The Company adopted the New Leasing Standard on August 1, 2019. The Company elected the optional transition method as well as the available package of practical expedients. As a result, the Company recognized right-of-use assets and the associated lease obligations, both totaling approximately $33 million, on the Condensed Consolidated Balance Sheet as of August 1, 2019. The adoption did not have a material impact to the Condensed Consolidated Statements of Income and Comprehensive Income. See Note 16 for further disclosures about the Company's leases. Other Accounting Standards Not Yet Adopted In January 2017, the FASB issued ASU No. 2017-04, "Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment," which eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (referred to as Step 2 in the goodwill impairment test). Instead, if the carrying amount of a reporting unit exceeds its fair value, an impairment charge equal to that excess shall be recognized, not to exceed the amount of goodwill allocated to the reporting unit. This ASU is effective for annual and any interim impairment tests for periods beginning after December 15, 2019, with early adoption permitted after January 1, 2017. This ASU is effective for the Company in its fiscal year 2021 beginning on August 1, 2020. The Company is currently evaluating the impact of this ASU on its consolidated financial statements, which will depend on the outcomes of future goodwill impairment tests.

Business Combinations [Abstract]
Acquisition - Erwin Hymer Group	Acquisition — Erwin Hymer Group On February 1, 2019, the Company acquired Erwin Hymer Group SE ("EHG"). EHG is headquartered in Bad Waldsee, Germany, and is one of the largest RV manufacturers in Europe. EHG is managed as a stand-alone operating entity and is included in the European recreational vehicle segment. In the first quarter of fiscal 2020, the Company made measurement period adjustments primarily related to the estimated fair value of certain deferred tax assets to better reflect the facts and circumstances that existed at the acquisition date. These adjustments resulted in a net decrease in deferred tax assets and a net increase of goodwill of $3,054. The following table summarizes the estimated fair values of the EHG assets acquired and liabilities assumed at the acquisition date. The Company is in the process of finalizing internal and third-party valuations of tangible and intangible assets and certain liabilities, therefore, the provisional estimates of intangible assets, fixed assets, goodwill, deferred income tax liabilities, income taxes payable and certain accrued liabilities are subject to change. The Company expects to finalize these values in the Company's fiscal quarter ending January 31, 2020.

Derivatives and Hedging

Derivatives and Hedging	3 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	Derivatives and Hedging The Company uses interest rate swap agreements, foreign currency forward contracts and certain non-derivative financial instruments to manage its risks associated with foreign currency exchange rates and interest rates. The Company does not hold derivative financial instruments of a speculative nature or for trading purposes. The Company records derivatives as assets and liabilities on the balance sheet at fair value. Changes in the fair value of derivative instruments are recognized in earnings unless the derivative qualifies and is designated as a hedge. Cash flows from derivatives are classified in the Condensed Consolidated Statements of Cash Flows in the same category as the cash flows from the items subject to designated hedge or undesignated (economic) hedge relationships. The Company evaluates hedge effectiveness at inception and on an ongoing basis. If a derivative is no longer expected to be effective, hedge accounting is discontinued. Certain of the Company’s derivative transactions are subject to master netting arrangements that allow the Company to net settle contracts with the same counter parties. These arrangements generally do not call for collateral and as of the applicable dates presented below, no cash collateral had been received or pledged related to the underlying derivatives. The fair value of our derivative instruments and the associated notional amounts, presented on a pre-tax basis, were as follows: October 31, 2019 July 31, 2019 Fair Value in Fair Value in Other Current Other Current Cash Flow Hedges Notional Liabilities Notional Liabilities Foreign currency forward contracts $ 51,799 $ 729 $ — $ — Interest rate swap agreements 798,200 16,641 849,550 12,463 Total derivative financial instruments $ 849,999 $ 17,370 $ 849,550 $ 12,463 The Company did not have any designated hedge instruments prior to February 1, 2019 . Cash Flow Hedges The Company utilizes foreign currency forward contracts to hedge the effect of certain foreign currency exchange rate fluctuations on forecasted foreign currency transactions, including foreign currency denominated sales. These forward contracts are designated as cash flow hedges. The changes in fair value of these contracts are recorded in accumulated other comprehensive income (“AOCI”) until the hedged items affect earnings, at which time the gain or loss is reclassified into the same line item in the determination of net income as the underlying exposure being hedged. Cash flow hedged forward contracts impacting AOCI are forecasted to occur over the next eight months. The Company has entered into interest rate swap agreements to manage certain of its interest rate exposures. During fiscal 2019, the Company entered into pay-fixed, receive-floating interest rate swap agreements, totaling $900,000 in initial value, in order to hedge against interest rate risk relating to the Company’s floating rate debt agreements. The $900,000 in initial value declines quarterly over the initial 4.5 year term of the swaps. The interest rate swaps are designated as cash flow hedges of the expected interest payments related to the Company’s LIBOR-based floating rate debt. Amounts initially recorded in AOCI will be reclassified to interest expense over the remaining life of the debt as the forecasted interest transactions occur. Net Investment Hedges The Company designates a portion of its outstanding Euro-denominated term loan tranche as a hedge of foreign currency exposures related to investments the Company has in certain Euro-denominated functional currency subsidiaries. The foreign currency transaction gains and losses on the Euro-denominated portion of the term loan, which is designated and effective as a hedge of the Company’s net investment in its Euro-denominated functional currency subsidiaries, are included as a component of the foreign currency translation adjustment. Losses included in the foreign currency translation adjustment for the three-month period ended October 31, 2019 were $1,254, net of tax. There were no amounts reclassified out of AOCI pertaining to the net investment hedge during the three months ended October 31, 2019. Derivatives Not Designated as Hedging Instruments On September 18, 2018, the Company entered into a definitive agreement to acquire EHG, which was later amended as of the February 1, 2019 closing date. The cash portion of the purchase price was denominated in Euro, and therefore the Company’s cash flows were exposed to changes in the Euro/USD exchange rate between the September 18, 2018 agreement date and the closing date. To reduce its exposure, the Company entered into a deal-contingent, foreign currency forward contract on the September 18, 2018 agreement date in the amount of 1.625 billion Euro. Hedge accounting was not applied to this instrument, and therefore all changes in fair value were recorded in earnings. This contract was settled in connection with the close of the EHG acquisition on February 1, 2019 in the amount of $70,777, resulting in a loss of the same amount. Of this $70,777 total loss, $42,555 was recognized in the three months ended October 31, 2018 and is included in Acquisition-related costs in the Condensed Consolidated Statements of Income and Comprehensive Income. The Company also has certain other derivative instruments, with a notional amount totaling approximately $34,990 and a fair value of $1,330, included in Other current liabilities in the Condensed Consolidated Balance Sheet as of October 31, 2019, which have not been designated as hedges and therefore hedge accounting is not applied. For these derivative instruments, changes in fair value are recognized in earnings. The Company also had certain other derivative instruments, with a notional amount totaling approximately $35,700 and a fair value of $1,226, included in Other current liabilities in the Condensed Consolidated Balance Sheet as of July 31, 2019. The total amounts presented in the Condensed Consolidated Statements of Income and Comprehensive Income due to changes in the fair value of the following derivative instruments are as follows: Three Months Ended October 31, 2019 Gain (Loss) on Derivatives Designated as Cash Flow Hedges Gain (Loss) recognized in Other Comprehensive Income, net of tax Foreign currency forward contracts $ (525) Interest rate swap agreements (3,197) Total gain (loss) $ (3,722) Three Months Ended October 31, 2019 Interest Expense Gain (Loss) Reclassified from AOCI, Net of Tax Foreign currency forward contracts $ — Interest rate swap agreements (495) Gain (Loss) on Derivatives Not Designated as Hedging Instruments Amount of gain (loss) recognized in income, net of tax Foreign currency forward contracts — Interest rate swap agreements (75) Total gain (loss) $ (570) Other than the deal-contingent foreign currency forward contract discussed above, there were no derivatives in place during the three-month period ended October 31, 2018.

The Company considers cash of 23,000 Euro ($25,654) that is pledged as collateral against certain revolving debt obligations related to its European rental fleet operations to be restricted cash. Additionally, cash of 11,700 Euro ($13,050) is restricted pending collateral modification of certain debt. Deferred compensation plan assets represent investments in securities (primarily mutual funds) traded in an active market held for the benefit of certain employees of the Company as part of a deferred compensation plan. Deferred compensation plan asset balances are recorded as a component of Other long-term assets in the Condensed Consolidated Balance Sheets. An equal and offsetting liability is also recorded in regards to the deferred compensation plan as a component of Other long-term liabilities in the Condensed Consolidated Balance Sheets. Changes in the fair value of the plan assets and the related liabilities are reflected in Other income (expense), net and Selling, general and administrative expenses, respectively, in the Condensed Consolidated Statements of Income and Comprehensive Income. Foreign currency forward contracts outstanding at October 31, 2019 are used to exchange Pounds Sterling ("GBP") for Euro. The total notional value of these contracts at October 31, 2019 is 40,000 GBP ($51,799), and these contracts have various maturity dates through June 2020. The Company entered into interest rate swaps to convert a portion of the Company's long-term debt from floating rate to fixed rate debt. As of October 31, 2019, the outstanding swaps had notional contract values of $798,200, partially hedging the interest rate risk related to the Company's U.S. dollar term loan tranche that matures in February 2026. The fair value of foreign currency forward contracts is estimated by discounting the difference between the contractual forward price and the current available forward price for the residual maturity of the contract using observable market rates. The fair value of interest rate swaps is calculated by discounting the estimated future cash flows based on the applicable observable yield curves.

As of July 31, 2019, the entire outstanding U.S. term loan tranche balance of $1,146,968 was subject to a LIBOR-base rate of 6.1875%, but the interest rate on $849,550 of that balance was fixed at 6.2160% through an interest rate swap by swapping the underlying 1-month LIBOR rate for a fixed rate of 2.4660%. The total interest rate on both the October 31, 2019 and July 31, 2019 outstanding Euro term loan tranche balance of $683,835 and $685,373, respectively, was 4.00%. In addition, the Company must make mandatory prepayments of principal under the term loan agreement upon the occurrence of certain specified events, including certain asset sales, debt issuances and receipt of annual cash flows in excess of certain amounts. No such specified events occurred during the three months ended October 31, 2019. As of October 31, 2019, the total interest rate on the outstanding ABL borrowings of $36,808 was 1.25%. The ABL also includes a 0.25% unused facility fee. The Company may, generally at its option, pay any borrowings under the ABL, in whole or in part, at any time and from time to time, without premium or penalty. The unused availability under the ABL is generally available to the Company for general operating purposes and, based on October 31, 2019 eligible accounts receivable and inventory balances, totaled approximately $668,000. The unsecured notes of 25,000 Euro ($27,885) relate to long-term debt assumed at the closing of the acquisition of EHG. There are two series, 20,000 Euro ($22,308) with an interest rate of 1.945% maturing in March 2025, and 5,000 Euro ($5,577) with an interest rate of 2.534% maturing February 2028. Other debt relates primarily to real estate loans with varying maturity dates through September 2032 and interest rates ranging from 1.40% - 3.43%.

The carrying value of the Company’s long-term debt, excluding debt issuance costs, approximates fair value at October 31, 2019 as the balance is subject to variable market interest rates that the Company believes are market rates for a similarly situated Company. The fair value of the Company's debt is largely estimated using Level 2 inputs as defined by ASC 820.

Income Tax Disclosure [Abstract]
Provision for Income Taxes	Provision for Income Taxes The overall effective income tax rate for the three months ended October 31, 2019 was 24.5%. The rate was favorably impacted by certain foreign rate differences which include certain interest income not subject to corporate income tax. This benefit was partially offset by additional income tax expense resulting from the vesting of share-based compensation awards during the three months ended October 31, 2019. The overall effective income tax rate for the three months ended October 31, 2018 was 55.7%. Included in this rate was the non-deductible foreign currency forward contract loss of $42,555 as discussed in Note 5 to the Condensed Consolidated Financial Statements. Under federal income tax law, the loss recognized for financial statement purposes was not deductible for federal income tax purposes. Within the next 12 months, the Company anticipates a decrease of approximately $3,800 in unrecognized tax benefits, and $850 in accrued interest related to unrecognized tax benefits recorded as of October 31, 2019, from expected settlements or payments of uncertain tax positions and lapses of the applicable statutes of limitations. Actual results may differ from these estimates.

Commitments and Contingencies Disclosure [Abstract]
Contingent Liabilities, Commitments and Legal Matters	Contingent Liabilities, Commitments and Legal Matters The Company’s total commercial commitments under standby repurchase obligations on global dealer inventory financing were $2,848,310 and $2,961,019 as of October 31, 2019 and July 31, 2019. The commitment term is generally up to eighteen months. The Company accounts for the guarantee under repurchase agreements of dealers’ financing by deferring a portion of the related product sale that represents the estimated fair value of the guarantee at inception. This deferred amount is included in the repurchase and guarantee reserve balances of $8,888 and $9,575 as of October 31, 2019 and July 31, 2019, respectively, which are included in Other current liabilities in the Condensed Consolidated Balance Sheets. Losses incurred related to repurchase agreements that were settled during the three-month periods ended October 31, 2019 and October 31, 2018 were not material. Based on current market conditions, the Company believes that any future losses under these agreements will not have a material effect on the Company’s consolidated financial position, results of operations or cash flows. The Company is also involved in certain litigation arising out of its operations in the normal course of its business, most of which is based upon state “lemon laws,” warranty claims and vehicle accidents (for which the Company carries insurance above a specified self-insured retention or deductible amount). The outcomes of legal proceedings and claims brought against the Company are subject to significant uncertainty. There is significant judgment required in assessing both the probability of an adverse outcome and the determination as to whether an exposure can be reasonably estimated. Based on current conditions, and in management’s opinion, the ultimate disposition of any current legal proceedings or claims against the Company will not have a material effect on the Company’s financial condition, operating results or cash flows. Litigation is, however, inherently uncertain and an adverse outcome from such litigation could have a material effect on the operating results of a particular reporting period.

Leases	Leases On August 1, 2019, the Company adopted new accounting guidance under Accounting Standards Codification Topic 842 ("ASC 842") Leases. ASC 842 established new criteria for recognizing right-of-use assets and lease liabilities for operating lease arrangements. The Company elected to adopt this guidance utilizing the optional transition method that allowed the Company to implement this new guidance prospectively, and to only include the disclosures required under ASC 842 for the periods subsequent to adoption. The Company has operating leases principally for land, buildings and equipment and also leases certain real estate under various finance leases expiring between calendar 2019 and 2028. Leases with an initial term of 12 months or fewer and which do not include an option to purchase the underlying asset that the Company is reasonably certain to exercise are not recorded on the balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the term of the lease. Certain of the Company's leases include options to extend or terminate the leases and these options have been included in the relevant lease term to the extent that they are reasonably certain to be exercised. The Company has elected the practical expedient to not separate non-lease components from the lease components to which they relate, and instead account for each separate lease and non-lease component associated with that lease component as a single lease component for all underlying asset classes. Accordingly, all costs associated with a lease contract are accounted for as lease costs. Lease costs are recorded in Cost of products sold, Selling, general, and administrative expenses and Interest expense in the Condensed Consolidated Statements of Income and Comprehensive Income. The Company does not include significant restrictions or covenants in our lease agreements, and residual value guarantees are not generally included within our operating leases. The components of lease costs for the three-month period ended October 31, 2019 were as follows: Three Months Ended October 31, 2019 Operating lease cost $ 3,031 Finance lease cost Amortization of right-of-use assets 136 Interest on lease liabilities 137 Total lease cost $ 3,304 Other information related to leases was as follows: Three Months Ended Supplemental Cash Flows Information October 31, 2019 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 3,005 Right-of-use assets obtained in exchange for lease obligations: Operating leases $ 278 Supplemental Balance Sheet Information October 31, 2019 Operating leases: Operating lease right-of-use assets $ 32,008 Other current liabilities 4,307 Other long-term liabilities 27,825 Total operating lease liabilities $ 32,132 Finance leases: Finance lease right-of-use assets $ 4,079 Other current liabilities 449 Other long-term liabilities 5,134 Total finance lease liabilities $ 5,583 October 31, 2019 Weighted-average remaining lease term Operating leases 14.5 years Finance leases 7.6 years Weighted-average discount rate Operating leases 3.4 % Finance leases 9.7 % Future minimum rental payments required under operating and finance leases as of October 31, 2019 were as follows: Operating Leases Financing Leases For the remainder of the fiscal year ending July 31, 2020 $ 7,127 $ 729 For the fiscal year ending July 31, 2021 7,370 991 For the fiscal year ending July 31, 2022 5,912 1,013 For the fiscal year ending July 31, 2023 4,144 1,036 For the fiscal year ending July 31, 2024 3,526 1,059 For the fiscal year ending July 31, 2025 and thereafter 20,845 3,092 Total future lease payments $ 48,924 $ 7,920 Less: amount representing interest (16,792) (2,337) Total reported lease liability $ 32,132 $ 5,583 Future minimum rental payments required under operating and finance leases as of July 31, 2019 were as follows: Operating Leases Finance Leases For the fiscal year ending July 31, 2020 $ 8,785 $ 974 For the fiscal year ending July 31, 2021 6,809 993 For the fiscal year ending July 31, 2022 5,437 1,015 For the fiscal year ending July 31, 2023 3,980 1,037 For the fiscal year ending July 31, 2024 3,424 1,061 For the fiscal year ending July 31, 2025 and thereafter 20,745 3,037 Total future lease payments $ 49,180 8,117 Less: amount representing interest (2,427) Total lease liability 5,690 Less: current portion (444) Long-term finance lease obligations $ 5,246

Equity [Abstract]
Stockholders' Equity	Stockholders’ Equity Stock-Based Compensation Under the Company’s restricted stock unit (“RSU”) program, RSU awards have been approved each October related to the financial performance of the most recently completed fiscal year since October 2012. The awarded employee restricted stock units vest, and shares of common stock are issued, in equal installments on the first, second and third anniversaries of the date of grant. In addition, concurrent with the timing of the employee awards, the Nominating and Governance Committee of the Board of Directors (“Board”) has awarded restricted stock units to Board members that will vest, and shares of common stock will be issued, on the first anniversary of the date of the grant. In September 2019, the Board approved changes to the equity compensation program for certain members of the Company’s executive management. Under the revised program, a portion of their equity compensation will be determined based on performance related to targets set for both the Company’s return on invested capital and free cash flow during a multi-year measurement period (North American operations only and a two-year measurement period for fiscal year 2020 grants). These performance stock unit (“PSU”) awards are based on a sliding scale of actual performance against relevant goals within a range of fifty percent (50%) to one hundred fifty percent (150%) of the target compensation. Performance below the fifty percent (50%) threshold will result in no earned shares, while performance above the one hundred fifty percent (150%) level would result in an award of shares equal in value to two times the amount of target compensation. In deriving the number of shares earned, if any, both performance metrics will be weighted equally. Following the measurement period, in accordance with actual achievement and certification of performance metrics, fully vested shares of common stock will be issued to the award recipients. The fair value of the PSU awards is determined using the Company’s stock price on the grant date. These awards are equity classified and will be expensed over the applicable measurement period based on the extent to which the performance metrics are probable of achievement. Total stock-based compensation expense recognized in the three-month periods ended October 31, 2019 and October 31, 2018 for these RSU and PSU awards totaled $5,013 and $4,530, respectively.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	Nature of Operations Thor Industries, Inc. was founded in 1980 and is the sole owner of operating subsidiaries (collectively, the “Company” or "Thor"), that, combined, represent the world's largest manufacturer of recreational vehicles (“RVs”). The Company manufactures a wide variety of RVs in the United States and Europe and sells those vehicles, as well as related parts and accessories, primarily to independent, non-franchise dealers throughout the United States, Canada and Europe. Unless the context requires or indicates otherwise, all references to “Thor,” the “Company,” “we,” “our” and “us” refer to Thor Industries, Inc. and its subsidiaries. The July 31, 2019 amounts are derived from the annual audited financial statements of Thor. The interim financial statements are unaudited. In the opinion of management, all adjustments (which consist of normal, recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows for the interim periods presented have been made. These financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2019. Due to seasonality within the recreational vehicle industry, among other factors, annualizing the results of operations for the three months ended October 31, 2019 would not necessarily be indicative of the results expected for the full fiscal year.
Adoption of Revenue Recognition Accounting Standard	Recently Adopted Accounting Standards In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842),” and has subsequently issued ASU's 2018-10, "Codification Improvements (Topic 842)," and 2018-11, "Targeted Improvements (Topic 842)" (collectively the "New Leasing Standard"), which provide guidance on the recognition, measurement, presentation, and disclosure of leases. The New Leasing Standard requires the recognition of lease assets and lease liabilities by lessees for all leases with terms greater than 12 months. The principal difference from prior guidance is that the lease assets and lease liabilities arising from operating leases are now recognized on the Condensed Consolidated Balance Sheet. The New Leasing Standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. The Company adopted the New Leasing Standard on August 1, 2019. The Company elected the optional transition method as well as the available package of practical expedients. As a result, the Company recognized right-of-use assets and the associated lease obligations, both totaling approximately $33 million, on the Condensed Consolidated Balance Sheet as of August 1, 2019. The adoption did not have a material impact to the Condensed Consolidated Statements of Income and Comprehensive Income. See Note 16 for further disclosures about the Company's leases.
Other Accounting Standards Not Yet Adopted	Other Accounting Standards Not Yet Adopted In January 2017, the FASB issued ASU No. 2017-04, "Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment," which eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (referred to as Step 2 in the goodwill impairment test). Instead, if the carrying amount of a reporting unit exceeds its fair value, an impairment charge equal to that excess shall be recognized, not to exceed the amount of goodwill allocated to the reporting unit. This ASU is effective for annual and any interim impairment tests for periods beginning after December 15, 2019, with early adoption permitted after January 1, 2017. This ASU is effective for the Company in its fiscal year 2021 beginning on August 1, 2020. The Company is currently evaluating the impact of this ASU on its consolidated financial statements, which will depend on the outcomes of future goodwill impairment tests.
