Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Basis of Presentation, and Summary of Significant Accounting Policies	Organization, Basis of Presentation, and Summary of Significant Accounting Policies Organization Malibu Boats, Inc. (together with its subsidiaries, the “Company” or "Malibu"), a Delaware corporation formed on November 1, 2013, is the sole managing member of Malibu Boats Holdings, LLC, a Delaware limited liability company (the "LLC"). The Company operates and controls all of the LLC's business and affairs and, therefore, pursuant to Financial Accounting Standards Board ("FASB") Accounting Standards Codification (“ASC”) Topic 810, Consolidation, consolidates the financial results of the LLC and its subsidiaries, and records a non-controlling interest for the economic interest in the Company held by the non-controlling holders of units in the LLC ("LLC Units"). Malibu Boats Holdings, LLC was formed in 2006 with Malibu's acquisition by an investor group, including affiliates of Black Canyon Capital LLC, Horizon Holdings, LLC and then-current management. The LLC, through its wholly owned subsidiary, Malibu Boats, LLC, is engaged in the design, engineering, manufacturing and marketing of innovative, high-quality, recreational powerboats that are sold through a world-wide network of independent dealers. On July 6, 2017, the Company acquired all outstanding units of Cobalt Boats, LLC (“Cobalt”) further expanding the Company's product offering across a broader segment of the recreational boating industry including performance sport boats, sterndrive and outboard boats. As a result of the acquisition, the Company consolidates the financial results of Cobalt. On October 15, 2018, the Company's subsidiary Malibu Boats, LLC, purchased the assets of Pursuit Boats ("Pursuit") from S2 Yachts, Inc., expanding the Company's product offering into the fiberglass outboard fishing boat market. COVID-19 Pandemic In March 2020, the World Health Organization characterized the coronavirus (“COVID-19”) a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. The COVID-19 pandemic has significantly impacted health and economic conditions throughout the United States. The COVID-19 pandemic has impacted the Company’s operations and financial results. Due to the impact of the COVID-19 pandemic, the Company elected to suspend operations at all of its facilities on March 24, 2020, which impacted the last week of fiscal third quarter. The shut-down continued into the fourth quarter with operations resuming between late April and early May, depending on the facility. Due to the rapidly changing business environment, unprecedented market volatility and heightened degree of uncertainty resulting from COVID-19, the Company cannot reasonably estimate the length or severity of the pandemic or its impact on the Company’s liquidity, results of operations, and financial condition, which could have a material adverse effect. Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim condensed financial statements and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all information and disclosures of results of operations, financial position and changes in cash flow in conformity with GAAP for complete financial statements. Such statements should be read in conjunction with the audited consolidated financial statements and notes thereto of Malibu Boats, Inc. and subsidiaries for the year ended June 30, 2019, included in the Company's Annual Report on Form 10-K. In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements reflect all adjustments considered necessary to present fairly the Company’s financial position at March 31, 2020, and the results of its operations for the three and nine month periods ended March 31, 2020 and March 31, 2019, and its cash flows for the nine month periods ended March 31, 2020 and March 31, 2019. Operating results for the three and nine months ended March 31, 2020, are not necessarily indicative of the results that may be expected for the full year ending June 30, 2020. Certain reclassifications have been made to the prior period presentation to conform to the current period presentation. Units and shares are presented as whole numbers while all dollar amounts are presented in thousands, unless otherwise noted. Segment Information Effective July 1, 2019, the Company revised its segment reporting to conform to changes in its internal management reporting based on the Company’s boat manufacturing operations. Segment information has been revised for comparison purposes for all periods presented in the condensed consolidated financial statements. The Company previously had four reportable segments, Malibu U.S., Malibu Australia, Cobalt and Pursuit. The Company now aggregates Malibu U.S. and Malibu Australia into one reportable segment as they have similar economic characteristics and qualitative factors. As a result the Company now has three reportable segments, Malibu, Cobalt and Pursuit. See Note 18 for revised segment information for the current and prior periods. Principles of Consolidation The accompanying unaudited interim condensed consolidated financial statements include the operations and accounts of the Company and all subsidiaries thereof. All intercompany balances and transactions have been eliminated upon consolidation. Recent Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, Leases (Topic 842). The amendments in this update create ASC Topic 842, Leases, and supersede the requirements in ASC Topic 840, Leases. ASC Topic 842 requires lessees to recognize on the balance sheet a right-of-use asset, representing its right to use the underlying asset for the lease term, and a lease liability for all leases with terms greater than 12 months. The guidance also requires qualitative and quantitative disclosures designed to assess the amount, timing, and uncertainty of cash flows arising from leases. The standard requires the use of a modified retrospective transition approach, which includes a number of optional practical expedients that entities may elect to apply. In June 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvement, which provides entities with an additional (optional) transition method to adopt the new lease standard. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. On July 1, 2019, the Company adopted the new leasing standard and all the related amendments. The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed the Company to carry forward the historical lease classification. The Company made an accounting policy election to not record leases with an initial term of 12 months or less on the balance sheet. The Company also 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 payments associated with a lease contract are accounted for as lease cost. The adoption of ASC Topic 842 did not have a material impact on the Company’s consolidated results of operations, equity or cash flows as of the adoption date. Under the optional transition approach, comparative information was not restated, but will continue to be reported under the standards in effect for those periods. See Note 11 for further information regarding the Company’s leases. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and in November 2018 issued a subsequent amendment, ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses. ASU 2016-13 significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. ASU 2016-13 will replace today’s “incurred loss” approach with an “expected loss” model for instruments measured at amortized cost. ASU 2018-19 will affect loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope of this amendment that have the contractual right to receive cash. ASU 2016-13 is effective for fiscal years and interim periods beginning after December 15, 2019, and is effective for the Company’s fiscal year beginning July 1, 2020. The adoption of the ASU is not expected to have a material impact on the Company’s consolidated financial position, results of operations, equity or cash flows. There are no other new accounting pronouncements that are expected to have a significant impact on the Company's consolidated financial statements and related disclosures.
