Business Combinations [Abstract]
Business Acquisition	Business Acquisition On January 22, 2021, the Company entered into a definitive agreement to acquire Luxco, Inc. and its affiliated companies (“Luxco”, or “Luxco Companies”), and subsequently completed the merger on April 1, 2021. Luxco is a leading branded beverage alcohol company across various categories, with a more than 60-year business heritage. As a result of the Luxco acquisition, MGP expects to increase its scale and market position in the branded-spirits sector and strengthen its platform for future growth of higher valued-added products. Following the merger, the Luxco Companies became wholly-owned subsidiaries of the Company. The aggregate consideration paid by the Company in connection with the merger was $237,500 in cash (less assumed indebtedness) and 5,007,833 shares of common stock of the Company, subject to adjustment for fractional shares (the “Company Shares,” and together with the cash portion, the “Merger Consideration”). The Company Shares were valued at $296,213 and represent approximately 22.8 percent of the Company’s outstanding common stock immediately following the closing of the merger. The Merger Consideration is subject to customary purchase price adjustments, including working capital, which adjustments are anticipated to be paid in cash. The cash portion of the Merger Consideration, the repayment of assumed debt, and transaction-related expenses were financed with a $242,300 borrowing under the Credit Agreement which was drawn down on April 1, 2021. For tax purposes, the transaction is structured partially as a tax-free reorganization and partially as a taxable acquisition, as defined in the Internal Revenue Code. The Company anticipates the amount transferred in a tax deferred manner, under the tax-free reorganization rules, will not create additional tax basis for the Company. The taxable component of the transaction will create additional tax basis and a corresponding future tax deduction for the Company. The Company is currently evaluating the potential effect of this acquisition on its tax profile. MGP does not expect the transaction to have a material effect on the Company’s estimates related to the use of the Company’s existing deferred tax assets or its estimates related to its existing unrecognized tax benefits based on the information available to date. Due to the limited time since the acquisition date and the size and complexity of the transaction, the business combination accounting is still in progress. The Company is currently in the process of finalizing the accounting for this transaction and expects to have preliminary allocation of the purchase consideration to the assets acquired and liabilities assumed by the end of the second quarter of 2021. We expect that this will result in goodwill and intangibles as well as other tangibles assets such as accounts receivable, inventories and property, plant and equipment. The major classes of liabilities assumed include accounts payable, accrued expenses and other long-term liabilities. We are currently in the process of determining the fair values of the acquired assets and assumed liabilities with the assistance of a third party specialist. During the quarter ended March 31, 2021, the Company has incurred $1,890 of transaction related costs, which are included in Selling, general and administrative expenses on the Condensed Consolidated Statements of Income.
