Recapitalization and Initial Public Offering	Recapitalization and Initial Public Offering Recapitalization Immediately prior to the closing of the Company’s IPO on February 5, 2014, a new single class of LLC Units of the LLC was allocated among the pre-IPO owners of the LLC in exchange for their prior membership interests of the LLC pursuant to the distribution provisions of the former limited liability company agreement of the LLC based upon the liquidation value of the LLC, assuming it was liquidated at the time of the IPO with a value implied by the IPO price of the shares of Class A Common Stock sold in the IPO. Immediately prior to the closing of the IPO, there were 17,071,424 LLC Units issued and outstanding. In addition, 34 shares of Class B Common Stock were issued, one to each existing LLC Unit holders. Further, on February 4, 2014, prior to the closing of the IPO, two holders of membership interests in the LLC merged with and into two newly formed subsidiaries of Malibu Boats, Inc. As a result of these mergers, the sole stockholders of each of the two merging entities received shares of Class A Common Stock in exchange for shares of capital stock of the merging entities. Also, the Company redeemed for nominal consideration the initial 100 shares of Class A Common Stock issued to the Company's initial stockholder in connection with its formation. The foregoing transactions are referred to as the “Recapitalization.” The Company accounted for the Recapitalization as a non-substantive transaction in a manner similar to a transaction between entities under common control pursuant to ASC 805, "Business Combinations". Accordingly, after the Recapitalization, the assets and liabilities of the Company are reflected at their carryover basis. The acquisition of LLC units from the LLC Unit holders is accounted for under the general guidance of ASC Topic 810, "Consolidation", and ASC Topic 740, "Income Taxes", for transactions with noncontrolling shareholders, which states that the direct tax effects of a transaction with noncontrolling parties should be accounted for within equity. IPO On February 5, 2014, the Company completed its IPO of 8,214,285 shares of Class A Common Stock at a price to the public of $14.00 per share for aggregate gross proceeds of $115,000. Of these proceeds, the Company received $99,512 and the selling shareholders received $7,438 after underwriting discounts and commissions of $8,050. Of the shares of Class A Common Stock sold to the public, 7,642,996 shares were issued and sold by the Company and 571,289 shares were sold by selling stockholders. This included 899,252 shares issued and sold by the Company and 172,175 shares sold by selling stockholders pursuant to the over-allotment option granted to the underwriters, which was exercised concurrently with the closing of the IPO. The Company used $69,750 of the net proceeds from the IPO to purchase LLC Units from the LLC and caused the LLC to use these proceeds (i) to pay down all of the amounts owed under the LLC’s credit facilities and term loans in an amount equal to $63,410, (ii) to pay Malibu Boats Investor, LLC, an affiliate of the LLC, a fee of $3,750 upon the consummation of the IPO in connection with the termination of the LLC’s management agreement, and (iii) for general corporate purposes with the remaining amount of approximately $2,700. The Company used all of the remaining net proceeds from the IPO, or $29,762, to purchase LLC Units from the existing owners of the LLC at a purchase price equal to the initial public offering price per share of Class A Common Stock in the IPO, after deducting underwriting discounts and commissions. In connection with the repayment of the LLC’s credit facilities and term loans, debt issuance costs associated with the term loans were written off to interest expense. First Amended and Restated Limited Liability Company Agreement In connection with the Recapitalization and IPO, the Company became the sole managing member of the LLC and, through the LLC, operates the business of the LLC. Accordingly, although the Company acquired a 49.3% economic interest in the LLC immediately following the closing of the IPO, the Company has 100% of the voting power and controls the management of the LLC. Holders of LLC Units generally do not have voting rights under the first amended and restated limited liability company agreement of the LLC, as amended (the “LLC Agreement”). Net profits and net losses of the LLC will generally be allocated to the LLC’s members (including the Company) pro rata in accordance with the percentages of their respective limited liability company interests. The LLC Agreement provides for cash distributions to the holders of LLC Units if the Company determines that the taxable income of the LLC will give rise to taxable income for its members. In accordance with the LLC Agreement, the Company intends to cause the LLC to make cash distributions to holders of LLC Units for purposes of funding their tax obligations in respect of the income of the LLC that is allocated to them. Exchange Agreement In connection with the Recapitalization and IPO, the Company entered into an exchange agreement (the “Exchange Agreement”) with the pre-IPO owners of the LLC, several of whom are directors and/or officers of the Company. Under the Exchange Agreement, each pre-IPO owner of the LLC (and certain permitted transferees thereof) has the right to exchange its LLC Units for shares of Class A Common Stock of the Company on a one-for-one basis, subject to customary conversion rate adjustments for stock splits, stock dividends and reclassifications, or at the Company's option, except in the event of a change in control, for a cash payment equal to the market value of the Class A Common Stock. The Exchange Agreement provides, however, that such exchanges must be for a minimum of the lesser of 1,000 LLC Units, all of the LLC Units held by the holder, or such amount as we determine to be acceptable. Further, the Exchange Agreement provides that LLC members do not have the right to exchange LLC Units if the Company determines that such exchange would be prohibited by law or regulation or would violate other agreements with the Company to which the LLC member may be subject or any of the Company's written policies related to unlawful or insider trading. The Exchange Agreement also provides that the Company may impose additional restrictions on exchanges that it determines to be necessary or advisable so that the LLC is not treated as a “publicly traded partnership” for U.S. federal income tax purposes. In addition, pursuant to the LLC Agreement, the Company as managing member of the LLC, has the right to require all members of the LLC to exchange their LLC Units for Class A Common Stock in accordance with the terms of the Exchange Agreement, subject to the consent of the holders of a majority of outstanding LLC Units other than those held by the Company. Tax Receivable Agreement As a result of exchanges of LLC Units into Class A Common Stock and purchases by the Company of LLC Units from holders of LLC Units, the Company will become entitled to a proportionate share of the existing tax basis of the assets of the LLC at the time of such exchanges or purchases. In addition, such exchanges and purchases of LLC Units are expected to result in increases in the tax basis of the assets of the LLC that otherwise would not have been available. These increases in tax basis may reduce the amount of tax that the Company would otherwise be required to pay in the future. These increases in tax basis may also decrease gains (or increase losses) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets. In connection with the Recapitalization and IPO, the Company entered into a tax receivable agreement (the “Tax Receivable Agreement”) with the pre-IPO owners of the LLC that provides for the payment by the Company to the pre-IPO owners (or their permitted assignees) of 85% of the amount of the benefits, if any, that the Company is deemed to realize as a result of (i) increases in tax basis and (ii) certain other tax benefits related to the Company entering into the Tax Receivable Agreement, including those attributable to payments under the Tax Receivable Agreement. These payment obligations are obligations of the Company and not of the LLC. For purposes of the Tax Receivable Agreement, the benefit deemed realized by the Company will be computed by comparing the actual income tax liability of the Company (calculated with certain assumptions) to the amount of such taxes that the Company would have been required to pay had there been no increase to the tax basis of the assets of the LLC as a result of the purchases or exchanges, and had the Company not entered into the Tax Receivable Agreement. The Tax Receivable Agreement further provides that, upon certain mergers, asset sales or other forms of business combinations or other changes of control, the Company (or its successor) would owe to the pre-IPO owners (or any permitted assignees) of the LLC a lump-sum payment equal to the present value of all forecasted future payments that would have otherwise been made under the Tax Receivable Agreement that would be based on certain assumptions, including a deemed exchange of LLC Units and that the Company would have sufficient taxable income to fully utilize the deductions arising from the increased tax basis and other tax benefits related to entering into the Tax Receivable Agreement. The Company also is entitled to terminate the Tax Receivable Agreement, which, if terminated, would obligate the Company to make early termination payments to the pre-IPO owners of the LLC. In addition, a pre-IPO owner may elect to unilaterally terminate the Tax Receivable Agreement with respect to such pre-IPO owner, which would obligate the Company to pay to such existing owner certain payments for tax benefits received through the taxable year of the election. Capitalization of Offering Costs Capitalized offering costs include costs directly attributable to the IPO. Prior to the IPO, we had capitalized approximately $1,498 of offering costs as prepaid assets. Upon closing of the IPO on February 5, 2014, these costs were netted against the proceeds of the IPO and, as such, were reclassified into additional paid in capital.

Recapitalization and Initial Public Offering

Recapitalization

Immediately prior to the closing of the Company’s IPO on February 5, 2014, a new single class of LLC Units of the LLC was allocated among the pre-IPO owners of the LLC in exchange for their prior membership interests of the LLC pursuant to the distribution provisions of the former limited liability company agreement of the LLC based upon the liquidation value of the LLC, assuming it was liquidated at the time of the IPO with a value implied by the IPO price of the shares of Class A Common Stock sold in the IPO. Immediately prior to the closing of the IPO, there were 17,071,424 LLC Units issued and outstanding. In addition, 34 shares of Class B Common Stock were issued, one to each existing LLC Unit holders. Further, on February 4, 2014, prior to the closing of the IPO, two holders of membership interests in the LLC merged with and into two newly formed subsidiaries of Malibu Boats, Inc. As a result of these mergers, the sole stockholders of each of the two merging entities received shares of Class A Common Stock in exchange for shares of capital stock of the merging entities. Also, the Company redeemed for nominal consideration the initial 100 shares of Class A Common Stock issued to the Company's initial stockholder in connection with its formation. The foregoing transactions are referred to as the “Recapitalization.”

The Company accounted for the Recapitalization as a non-substantive transaction in a manner similar to a transaction between entities under common control pursuant to ASC 805, "Business Combinations". Accordingly, after the Recapitalization, the assets and liabilities of the Company are reflected at their carryover basis.

IPO

On February 5, 2014, the Company completed its IPO of 8,214,285 shares of Class A Common Stock at a price to the public of $14.00 per share for aggregate gross proceeds of $115,000. Of these proceeds, the Company received $99,512 and the selling shareholders received $7,438 after underwriting discounts and commissions of $8,050. Of the shares of Class A Common Stock sold to the public, 7,642,996 shares were issued and sold by the Company and 571,289 shares were sold by selling stockholders. This included 899,252 shares issued and sold by the Company and 172,175 shares sold by selling stockholders pursuant to the over-allotment option granted to the underwriters, which was exercised concurrently with the closing of the IPO.

In connection with the repayment of the LLC’s credit facilities and term loans, debt issuance costs associated with the term loans were written off to interest expense.

First Amended and Restated Limited Liability Company Agreement

In connection with the Recapitalization and IPO, the Company became the sole managing member of the LLC and, through the LLC, operates the business of the LLC. Accordingly, although the Company acquired a 49.3% economic interest in the LLC immediately following the closing of the IPO, the Company has 100% of the voting power and controls the management of the LLC. Holders of LLC Units generally do not have voting rights under the first amended and restated limited liability company agreement of the LLC, as amended (the “LLC Agreement”).

Net profits and net losses of the LLC will generally be allocated to the LLC’s members (including the Company) pro rata in accordance with the percentages of their respective limited liability company interests. The LLC Agreement provides for cash distributions to the holders of LLC Units if the Company determines that the taxable income of the LLC will give rise to taxable income for its members. In accordance with the LLC Agreement, the Company intends to cause the LLC to make cash distributions to holders of LLC Units for purposes of funding their tax obligations in respect of the income of the LLC that is allocated to them.

Exchange Agreement

In connection with the Recapitalization and IPO, the Company entered into an exchange agreement (the “Exchange Agreement”) with the pre-IPO owners of the LLC, several of whom are directors and/or officers of the Company. Under the Exchange Agreement, each pre-IPO owner of the LLC (and certain permitted transferees thereof) has the right to exchange its LLC Units for shares of Class A Common Stock of the Company on a one-for-one basis, subject to customary conversion rate adjustments for stock splits, stock dividends and reclassifications, or at the Company's option, except in the event of a change in control, for a cash payment equal to the market value of the Class A Common Stock. The Exchange Agreement provides, however, that such exchanges must be for a minimum of the lesser of 1,000 LLC Units, all of the LLC Units held by the holder, or such amount as we determine to be acceptable. Further, the Exchange Agreement provides that LLC members do not have the right to exchange LLC Units if the Company determines that such exchange would be prohibited by law or regulation or would violate other agreements with the Company to which the LLC member may be subject or any of the Company's written policies related to unlawful or insider trading. The Exchange Agreement also provides that the Company may impose additional restrictions on exchanges that it determines to be necessary or advisable so that the LLC is not treated as a “publicly traded partnership” for U.S. federal income tax purposes. In addition, pursuant to the LLC Agreement, the Company as managing member of the LLC, has the right to require all members of the LLC to exchange their LLC Units for Class A Common Stock in accordance with the terms of the Exchange Agreement, subject to the consent of the holders of a majority of outstanding LLC Units other than those held by the Company.

Tax Receivable Agreement

As a result of exchanges of LLC Units into Class A Common Stock and purchases by the Company of LLC Units from holders of LLC Units, the Company will become entitled to a proportionate share of the existing tax basis of the assets of the LLC at the time of such exchanges or purchases. In addition, such exchanges and purchases of LLC Units are expected to result in increases in the tax basis of the assets of the LLC that otherwise would not have been available. These increases in tax basis may reduce the amount of tax that the Company would otherwise be required to pay in the future. These increases in tax basis may also decrease gains (or increase losses) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets.

In connection with the Recapitalization and IPO, the Company entered into a tax receivable agreement (the “Tax Receivable Agreement”) with the pre-IPO owners of the LLC that provides for the payment by the Company to the pre-IPO owners (or their permitted assignees) of 85% of the amount of the benefits, if any, that the Company is deemed to realize as a result of (i) increases in tax basis and (ii) certain other tax benefits related to the Company entering into the Tax Receivable Agreement, including those attributable to payments under the Tax Receivable Agreement. These payment obligations are obligations of the Company and not of the LLC. For purposes of the Tax Receivable Agreement, the benefit deemed realized by the Company will be computed by comparing the actual income tax liability of the Company (calculated with certain assumptions) to the amount of such taxes that the Company would have been required to pay had there been no increase to the tax basis of the assets of the LLC as a result of the purchases or exchanges, and had the Company not entered into the Tax Receivable Agreement.

The Tax Receivable Agreement further provides that, upon certain mergers, asset sales or other forms of business combinations or other changes of control, the Company (or its successor) would owe to the pre-IPO owners (or any permitted assignees) of the LLC a lump-sum payment equal to the present value of all forecasted future payments that would have otherwise been made under the Tax Receivable Agreement that would be based on certain assumptions, including a deemed exchange of LLC Units and that the Company would have sufficient taxable income to fully utilize the deductions arising from the increased tax basis and other tax benefits related to entering into the Tax Receivable Agreement. The Company also is entitled to terminate the Tax Receivable Agreement, which, if terminated, would obligate the Company to make early termination payments to the pre-IPO owners of the LLC. In addition, a pre-IPO owner may elect to unilaterally terminate the Tax Receivable Agreement with respect to such pre-IPO owner, which would obligate the Company to pay to such existing owner certain payments for tax benefits received through the taxable year of the election.

Capitalization of Offering Costs

Capitalized offering costs include costs directly attributable to the IPO. Prior to the IPO, we had capitalized approximately $1,498 of offering costs as prepaid assets. Upon closing of the IPO on February 5, 2014, these costs were netted against the proceeds of the IPO and, as such, were reclassified into additional paid in capital.
