Acquisitions	Acquisitions 3 Arts Entertainment On May 29, 2018, the Company purchased a 51% membership interest in 3 Arts Entertainment LLC, a talent management and television/film production company. The purchase price was approximately $166.6 million, of which 50% was paid in cash at closing, 32.5% was paid in the Company's Class B non-voting common shares at closing, and 17.5% will be paid in the Company's Class B non-voting common shares on the one-year anniversary of closing, subject to certain conditions. The number of shares issued and to be issued was determined by dividing the dollar value of the portion of the purchase price to be paid by the daily weighted average closing price of the Company's Class B non-voting common shares on the New York Stock Exchange for the twenty (20) consecutive trading days immediately preceding the closing date. The value of the shares issued or to be issued was based on the closing price of the Company's Class B non-voting common shares at closing. A portion of the purchase price, up to $38.3 million, may be recoupable for a five-year period commencing on the acquisition date of May 29, 2018, contingent upon the continued employment of certain employees, or the achievement of certain EBITDA targets, as defined in the 3 Arts Entertainment acquisition and related agreements. Accordingly, $38.3 million is recorded as a deferred compensation arrangement within other current and non-current assets and is being amortized in general and administrative expenses over a five-year period. The acquisition was accounted for as a purchase, with the results of operations of 3 Arts Entertainment included in the Company's consolidated results from May 29, 2018. Based on a preliminary purchase price allocation, $92.7 million was allocated to goodwill, $47.0 million was allocated to the fair value of finite-lived intangible assets (including measurement period adjustments recorded, see Note 5) and $38.3 million was allocated to deferred compensation arrangements, as discussed above. The remainder of the purchase price was primarily allocated to cash and cash equivalents, accounts receivable, other assets, and accounts payable and accrued liabilities, and $15.8 million was recorded as a redeemable noncontrolling interest, representing the noncontrolling interest holders' 49% equity interest in 3 Arts Entertainment (see Note 9). The acquired finite-lived intangible assets primarily represent customer relationships and are being amortized over a weighted average estimated useful life of 12 years. The Company incurred approximately $1.3 million of acquisition-related costs that were expensed in restructuring and other expenses during the nine months ended December 31, 2018. The preliminary allocation of the estimated purchase price is based upon management's estimates and is subject to revision, as a more detailed analysis of intangible assets, certain tangible assets, and other assets and liabilities is completed and additional information on the fair value of assets and liabilities becomes available, including receipt of final appraisals of the net assets acquired. A change in the fair value of the net assets may change the amount of the purchase price allocable to goodwill, and could impact the amounts of amortization expense. The Company used discounted cash flows ("DCF") analyses, which represent Level 3 fair value measurements, to assess certain components of its purchase price allocation, including acquired intangible assets and the redeemable noncontrolling interest. The acquisition goodwill arises from the opportunity for synergies of the combined companies to grow and strengthen the Company's television operations by expanding the Company's talent relationships, and improving the Company's television production capabilities. The goodwill recorded as part of this acquisition is included in the Television Production segment. The goodwill is not amortized for financial reporting purposes, but is deductible for federal tax purposes. Good Universe On October 11, 2017, the Company purchased all of the membership interests in True North Media, LLC ("Good Universe"), a motion picture production and global sales company. The purchase price consisted of $20.4 million in cash paid at closing, and an additional $1.4 million in cash and 119,751 of Class B non-voting common shares to be paid and issued after one-year of the closing date. In addition, the Company assumed $23.6 million of corporate debt and production loans, of which $14.9 million was paid off shortly following the acquisition during the fiscal year ended March 31, 2018. The acquisition was accounted for as a purchase, with the results of operations of Good Universe included in the Company's consolidated results from October 12, 2017. Based on the purchase price allocation, $29.0 million was allocated to goodwill, with the remainder primarily allocated to the fair values of investment in film and television programs, cash and cash equivalents, and other liabilities. The goodwill recorded as part of this acquisition arises from the executive management personnel and their extensive experience and key relationships in the entertainment industry, and is included in the Motion Picture segment (see Note 5). The goodwill is not amortized for financial reporting purposes, but is deductible for federal tax purposes.
