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”). Refer to Note 2. Malibu Boats Holdings, LLC was formed in 2006 with the acquisition by an investor group, including affiliates of Black Canyon Capital LLC, Horizon Holdings, LLC and then-current management. The LLC is engaged in the design, engineering, manufacturing, marketing and sale of a diverse range of innovative, high-quality recreational powerboats sold through a world-wide network of independent dealers. On July 6, 2017, the Company acquired all the 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 also consolidates the financial results of Cobalt. Refer to Note 3. The Company reports its results of operations under three reportable segments: Malibu U.S., Malibu Australia, and Cobalt, based on their boat manufacturing operations. 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, 2017, 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, 2018, and the results of its operations for the nine month periods ended March 31, 2018 and March 31, 2017, and its cash flows for the nine month periods ended March 31, 2018 and March 31, 2017. Operating results for the nine months ended March 31, 2018, are not necessarily indicative of the results that may be expected for the full year ending June 30, 2018. 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. Principles of Consolidation The accompanying unaudited 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. Offering and Prepayment of Term Loans On August 14, 2017, the Company completed an offering of 2,300,000 shares of Class A Common Stock that were issued and sold by the Company at a price to the public of $24.05 per share (the "Offering"). This included 300,000 shares issued and sold by the Company pursuant to the option granted to the underwriters, which was exercised concurrently with the closing of the Offering. The aggregate gross proceeds from the Offering was $58,075. Of these proceeds, the Company received $55,317 after deducting $2,758 in underwriting discounts and commissions. Of the net proceeds received from the Offering, $50,000 was used to repay amounts outstanding on its loans under the Credit Agreement (defined in Note 8). The remaining net proceeds were used for general working capital purposes. The Company exercised its option to apply the prepayment to principal installments through December 31, 2021, and a portion of principal installments due on March 31, 2022. Accordingly, no principal payments are required under the Credit Agreement until March 31, 2022, and as such, all borrowings as of March 31, 2018 and June 30, 2017, are reflected as noncurrent. Capitalized offering costs directly attributable to the Offering of $650 were netted against the proceeds and, as such, were reclassified into additional paid in capital. Immaterial Correction of an Error in Prior Periods During the second quarter of fiscal 2018, the Company identified an error related to an understatement of the non-controlling interest held by LLC Unit holders in the LLC, an overstatement to accumulated comprehensive loss, and an overstatement of additional paid in capital. When LLC units were exchanged for Class A Common Stock of Malibu Boats, Inc. during the quarters ended December 31, 2016 and March 31, 2017, the Company inadvertently reduced the non-controlling interest by the fair value of the Malibu Boats, Inc. Class A Common Stock (the fair value received) rather than the carrying value of the LLC units that were exchanged. In addition, the Company inadvertently did not allocate foreign currency translation adjustments ratably between Malibu Boats, Inc. and the non-controlling interest based on their respective pro-rata ownership interests in the LLC from October 2014 (the date the LLC acquired their Australian subsidiary) through September 30, 2017. In accordance with FASB ASC Topic 250, Accounting Changes and Error Corrections, the Company evaluated the materiality of the error from quantitative and qualitative perspectives, and concluded that the error was immaterial to the Company’s prior period interim and annual consolidated financial statements. Since the revision was not material to any prior period interim or annual consolidated financial statements, no amendments to previously filed interim or annual periodic reports are required. Consequently, the Company revised the historical consolidated financial information presented herein and will reflect the same revisions in its forthcoming fiscal 2018 Form 10-K. For the fiscal year ended June 30, 2017, the immaterial error correction resulted in an increase to the non-controlling interest of $1,869, a decrease to accumulated other comprehensive loss of $639, and a decrease to additional paid in capital of $2,508, within stockholders' equity on the unaudited condensed consolidated balance sheet and within the statement of stockholders' equity. There was no change in total stockholders’ equity for the fiscal year ended June 30, 2017. Recent Accounting Pronouncements In May 2014, the FASB and International Accounting Standards Board jointly issued a final standard on revenue recognition, Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. This standard will supersede most current revenue recognition guidance. Under the new standard, entities are required to identify the contract with a customer; identify the separate performance obligations in the contract; determine the transaction price; allocate the transaction price to the separate performance obligations in the contract; and recognize the appropriate amount of revenue when (or as) the entity satisfies each performance obligation. The standard is effective for fiscal years beginning after December 15, 2017. Entities have the option of using either the retrospective or cumulative effect transition method. The Company expects to adopt ASU 2014-09 for the Company's fiscal year beginning July 1, 2018 and expects to adopt the guidance using the modified retrospective approach. The Company has completed a preliminary assessment of the impact of ASU 2014-09 and other related ASU's, and does not anticipate that the impact of adoption will have a material impact to the Company's financial statements, accounting policies or processes. The Company anticipates that it will have to expand its revenue related disclosures as a result of adopting this ASU. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This guidance establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations and comprehensive income. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently assessing the potential impact of this ASU on its consolidated financial statements and footnote disclosures. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years with early adoption permitted. This guidance provides specific classification of how certain cash receipts and cash payments are presented in the statement of cash flows. The ASU should be applied using a retrospective transition method. If it is impracticable to apply the amendments retrospectively for some of the cash flow issues, the amendments for those issues should then be applied prospectively at the earliest date practicable. The Company is currently assessing the potential impact of this ASU on its presentation of the consolidated statement of cash flows. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The guidance clarifies the definition of a business that provides a two-step analysis in the determination of whether an acquisition or derecognition is a business or an asset. The update removes the evaluation of whether a market participant could replace any missing elements and provides a framework to assist entities in evaluating whether both an input and a substantive process are present. This guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods and early adoption is permitted for transactions that meet specified criteria. This guidance is to be applied on a prospective basis for transactions that occur after the effective date. 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.
