Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Unless otherwise noted in this report, any description of "we," "us" or "our" includes Molson Coors Brewing Company ("MCBC" or the "Company"), principally a holding company, and its operating and non-operating subsidiaries included within our reporting segments and Corporate. Our reporting segments include: MillerCoors LLC ("MillerCoors" or U.S. segment), operating in the U.S.; Molson Coors Canada ("MCC" or Canada segment), operating in Canada; Molson Coors Europe (Europe segment), operating in Bulgaria, Croatia, Czech Republic, Hungary, Montenegro, the Republic of Ireland, Romania, Serbia, the U.K. and various other European countries; and Molson Coors International ("MCI" or International segment), operating in various other countries. Unless otherwise indicated, information in this report is presented in USD and comparisons are to comparable prior periods. Our primary operating currencies, other than USD, include the CAD, the GBP, and our Central European operating currencies such as the EUR, CZK, HRK and RSD. The accompanying unaudited condensed consolidated interim financial statements reflect all adjustments which are necessary for a fair statement of the financial position, results of operations and cash flows for the periods presented in accordance with U.S. GAAP. Such unaudited interim condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These unaudited condensed consolidated interim financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2018 ("Annual Report"), and have been prepared on a consistent basis with the accounting policies described in Note 1 of the Notes to the Audited Consolidated Financial Statements included in our Annual Report, except as noted below and in Note 2, "New Accounting Pronouncements." The results of operations for the three and nine months ended September 30, 2019 are not necessarily indicative of the results that may be achieved for the full year. Due to the anti-dilutive effect resulting from the reported net loss attributable to MCBC for the three months ended September 30, 2019 , the impact of potentially dilutive securities has been excluded from the quarterly calculation of weighted-average shares for diluted EPS for the third quarter of 2019. The impact of these potentially dilutive securities has been included in the calculation of weighted-average shares for diluted EPS for the nine months ended September 30, 2019 . Non-Cash Activity Non-cash activity includes non-cash issuances of share-based awards, as well as non-cash investing activities related to movements in our guarantee of indebtedness of certain equity method investments. See Note 4, "Investments" for further discussion. We also had non-cash activities related to capital expenditures incurred but not yet paid of $126.3 million and $154.7 million for the nine months ended September 30, 2019 and September 30, 2018 , respectively. Other than the activity mentioned above and the supplemental non-cash activity related to the recognition of leases further discussed below, there was no other significant non-cash activity during the nine months ended September 30, 2019 and September 30, 2018 . Share-Based Compensation During the third quarter of 2019, our share-based compensation expense decreased by approximately $19 million , due to the reversal of cumulative compensation expense previously recognized for our 2018 and 2017 PSU awards as the achievement of the performance conditions are no longer deemed probable for the respective performance periods. Leases We account for leases in accordance with Accounting Standards Codification (“ASC”) Topic 842, Leases, which we adopted on January 1, 2019 , electing not to adjust comparative periods presented and applying a modified retrospective transition approach as of the effective date of adoption (see Note 2, "New Accounting Pronouncements" for impacts of adoption). We enter into contractual arrangements for the utilization of certain non-owned assets, primarily real estate and equipment, which are evaluated as finance (previously known as capital) or operating leases upon commencement and are accounted for accordingly. Specifically, under ASC 842, a contract is or contains a lease when, (1) the contract contains an explicitly or implicitly identified asset and (2) the customer obtains substantially all of the economic benefits from the use of that underlying asset and directs how and for what purpose the asset is used during the term of the contract in exchange for consideration. We assess whether an arrangement is or contains a lease at inception of the contract. For all contractual arrangements deemed to be leases (other than short-term leases), as of the lease commencement date, we recognize on the consolidated balance sheet a liability for our obligation related to the lease and a corresponding asset representing our right to use the underlying asset over the period of use. For leases that qualify as short-term leases, we have elected, for all classes of underlying assets, to not apply the balance sheet recognition requirements of ASC 842, and instead, we recognize the lease payments in the consolidated statements of operations on a straight-line basis over the lease term. We have also made the election, for our real estate and certain equipment classes of underlying assets, to account for lease and non-lease components as a single lease component. Our leases have remaining lease terms of up to approximately 18 years. Certain of our lease agreements contain options to extend or early terminate the agreement. The lease term used to calculate the right-of-use asset and lease liability at commencement includes the impacts of options to extend or terminate the lease when it is reasonably certain that we will exercise that option. When determining whether it is reasonably certain that we will exercise an option at commencement, we consider various existing economic factors, including real estate strategies, the nature, length, and terms of the agreement, as well as the uncertainty of the condition of leased equipment at the end of the lease term. Based on these determinations, we generally conclude that the exercise of renewal options would not be reasonably certain in determining the lease term at commencement. Assumptions made at the commencement date are re-evaluated upon occurrence of certain events requiring a lease modification. Additionally, for certain equipment leases involving groups of similar leased assets with similar lease terms, we apply a portfolio approach to effectively account for the operating lease right-of-use assets and liabilities. The discount rate used to calculate the present value of the future minimum lease payments is the rate implicit in the lease, when readily determinable. As the rate implicit in the lease is not readily determinable for most of our leases, we use our incremental borrowing rate relative to the leased asset. Certain of our leases include variable lease payments, including payments that depend on an index or rate, as well as variable payments for items such as property taxes, insurance, maintenance, and other operating expenses associated with leased assets. Payments that vary based on an index or rate are included in the measurement of our lease assets and liabilities at the rate as of the commencement date. All other variable lease payments are excluded from the measurement of our lease assets and liabilities and are recognized in the period in which the obligation for those payments is incurred. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. Lease-related expense is recorded within either cost of goods sold or marketing, general and administrative expenses on the consolidated statements of operations, depending on the function of the underlying leased asset, with the exception of interest on finance lease liabilities, which is recorded within interest income (expense), net on the consolidated statements of operations. Montreal Brewery Sale and Leaseback Transaction In June 2019, we completed the sale of our Montreal brewery for $96.2 million (CAD 126.0 million ), resulting in a $61.3 million gain, which was recorded as a special item. In conjunction with the sale, we agreed to lease back the existing property to continue operations on an uninterrupted basis for a period up to 5 years with early termination options at our discretion, while our new brewery in Longueuil, Quebec is being constructed. Accordingly, we have recorded operating lease right-of-use assets and liabilities of approximately CAD 6 million assuming a lease term that is coterminous with the construction of our new brewery, which is currently expected to be operational in 2021. However, due to the uncertainty inherent in our estimates, the term of the brewery lease is subject to reassessment. Once the existing property has been entirely redeveloped by the purchaser, we plan to lease a minor portion of the future space for administrative and other purposes. We have evaluated this transaction pursuant to the accounting guidance for sale and leaseback transactions and concluded that the relevant criteria was met for full gain recognition upon completion of the transaction in the second quarter of 2019. Lease Financial Information For the three and nine months ended September 30, 2019 , lease expense (including immaterial short-term and variable lease costs) was as follows: Three Months Ended September 30, 2019 Nine Months Ended September 30, 2019 (In millions) Operating lease expense $ 18.1 $ 54.2 Finance lease expense 2.9 8.7 Total lease expense $ 21.0 $ 62.9 Supplemental cash flow information related to leases for the nine months ended September 30, 2019 was as follows: Nine Months Ended September 30, 2019 (In millions) Cash paid for amounts included in the measurements of lease liabilities: Operating cash flows from operating leases $ 39.6 Operating cash flows from finance leases $ 2.7 Financing cash flows from finance leases $ 1.8 Supplemental non-cash information on right-of-use assets obtained in exchange for new lease liabilities: Operating leases $ 36.4 Finance leases $ 2.1 Supplemental balance sheet information related to leases as of September 30, 2019 was as follows: As of September 30, 2019 Balance Sheet Classification (In millions) Operating Leases Operating lease right-of-use assets Other assets $ 155.0 Current operating lease liabilities Accounts payable and other current liabilities $ 44.4 Non-current operating lease liabilities Other liabilities 120.8 Total operating lease liabilities $ 165.2 Finance Leases Finance lease right-of-use assets Properties, net $ 64.8 Current finance lease liabilities Current portion of long-term debt and short-term borrowings $ 33.9 Non-current finance lease liabilities Long-term debt 50.9 Total finance lease liabilities $ 84.8 The weighted-average remaining lease term and discount rate as of September 30, 2019 are as follows: Weighted-Average Remaining Lease Term (Years) Weighted-Average Discount Rate Operating leases 5.0 4.2% Finance leases 9.2 6.3% Based on foreign exchange rates as of September 30, 2019 , maturities of lease liabilities are as follows: Operating Leases Finance Leases (In millions) 2019 - remaining $ 13.6 $ 1.7 2020 48.2 38.0 2021 39.5 5.7 2022 30.4 5.7 2023 21.3 5.7 Thereafter 29.3 62.8 Total lease payments $ 182.3 $ 119.6 Less: interest (17.1 ) (34.8 ) Present value of lease liabilities $ 165.2 $ 84.8 Executed leases that have not yet commenced as of September 30, 2019 are immaterial.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements New Accounting Pronouncements Recently Adopted Leases In February 2016, the FASB issued authoritative guidance intended to increase transparency and comparability among organizations by requiring the recognition of lease assets and liabilities on the balance sheet and disclosure of key information about leasing arrangements. We adopted this guidance and all related amendments applying the modified retrospective transition approach to all lease arrangements as of the effective date of adoption, January 1, 2019 . As permitted under the guidance, financial statements for reporting periods beginning after January 1, 2019 are presented under the new guidance, while prior period amounts have not been adjusted and continue to be reported and disclosed in accordance with historical accounting guidance. Additionally, for existing leases as of the effective date, we have elected the package of practical expedients available at transition to not reassess the historical lease determination, lease classification and initial direct costs. For operating leases, the adoption of the new guidance resulted in the recognition of right-of-use assets of approximately $154 million and aggregate current and non-current lease liabilities of approximately $164 million as of January 1, 2019 , including immaterial reclassifications of prepaid and deferred rent balances into right-of-use assets. Separately, as a result of the cumulative impact of adopting the new guidance, we recorded a net increase to opening retained earnings of approximately $32 million as of January 1, 2019 with the offsetting impact within other assets, related to our share of the accelerated recognition of deferred gains on non-qualifying and other sale-leaseback transactions by an equity method investment within our Canada segment. Additionally, while our accounting for finance leases remains unchanged at adoption, we have prospectively changed the presentation of finance lease liabilities within the consolidated balance sheets to be presented within current portion of long-term debt and short-term borrowings, and long-term debt, as appropriate. As of January 1, 2019 , we reclassified approximately $3 million and $82 million of short-term and long-term finance lease liabilities from accounts payable and other current liabilities and other non-current liabilities to current portion of long-term debt and short-term borrowings and long-term debt, respectively. The adoption of this guidance had no impact to our cash flows from operating, investing, or financing activities. See Note 1, “Basis of Presentation and Summary of Significant Accounting Policies” for additional discussion on our leasing arrangements. Accumulated Other Comprehensive Income (Loss) In February 2018, the FASB issued authoritative guidance intended to improve the usefulness of financial information related to the enactment of the 2017 Tax Act. This guidance provides an option to reclassify from AOCI to retained earnings the stranded tax effects resulting from the change in the U.S. federal corporate income tax rate as a result of the 2017 Tax Act. We adopted this guidance as of January 1, 2019 and elected to reclassify stranded tax effects related to the 2017 Tax Act, resulting in an approximate $75 million increase to retained earnings in the period of adoption. Our policy is to release stranded tax effects from AOCI using either a specific identification approach or portfolio approach based on the nature of the underlying item. New Accounting Pronouncements Not Yet Adopted In August 2018, the FASB issued authoritative guidance intended to address a customer’s accounting for implementation costs incurred in a cloud computing arrangement that is a service contract. This guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The guidance also requires presentation of the capitalized implementation costs in the statement of financial position and in the statement of cash flows in the same line item that a prepayment for the fees of the associated hosting arrangement would be presented, and the expense related to the capitalized implementation costs to be presented in the same line item in the statement of operations as the fees associated with the hosting element (service) of the arrangement. This guidance is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods, with early adoption permitted. We are currently evaluating the potential impact on our financial position, results of operations and statement of cash flows upon adoption of this guidance, which will result in the change in presentation of capitalized implementation costs related to hosting arrangements from properties to other assets on the consolidated balance sheet, as well as the expense related to such costs no longer being classified as depreciation expense and cash flows related to those costs no longer being presented as investing activities.

Segment Reporting

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting Our reporting segments are based on the key geographic regions in which we operate, which are the basis on which our chief operating decision maker evaluates the performance of the business. Our reporting segments consist of the U.S., Canada, Europe and International. Corporate is not a reportable segment and primarily includes interest and certain other general and administrative costs that are not allocated to any of the operating segments as well as the results of our water resources and energy operations in Colorado and the unrealized changes in fair value on our commodity swaps not designated in hedging relationships recorded within cost of goods sold, which are later reclassified when realized to the segment in which the underlying exposure resides. Additionally, only the service cost component of net periodic pension and OPEB cost is reported within each operating segment, and all other components are reported within the Corporate segment. On October 28, 2019, as part of our revitalization plan, we made the determination to establish Chicago, Illinois as our North American operational headquarters, close our existing office in Denver, Colorado and consolidate certain administrative functions into our other existing office locations. In connection with these consolidation activities, effective January 1, 2020, we will change our management structure to two business units, our North America and Europe businesses. Accordingly, the segment financial reporting implications, if any, will not be reflected until the first quarter of 2020. No single customer accounted for more than 10% of our consolidated sales for the three and nine months ended September 30, 2019 or September 30, 2018 . Consolidated net sales represent sales to third-party external customers less excise taxes. Inter-segment transactions impacting net sales revenues and income (loss) before income taxes eliminate upon consolidation and are primarily related to U.S. segment sales to the other segments. The following tables present net sales and income (loss) before income taxes by segment: Three Months Ended Nine Months Ended September 30, 2019 September 30, 2018 September 30, 2019 September 30, 2018 (In millions) U.S. $ 1,890.5 $ 1,935.8 $ 5,561.4 $ 5,656.1 Canada 366.3 388.9 1,000.3 1,070.1 Europe 558.0 577.9 1,459.4 1,538.3 International 56.5 67.0 163.3 192.4 Corporate 0.1 0.2 0.6 0.7 Inter-segment net sales eliminations (29.8 ) (35.6 ) (91.8 ) (106.7 ) Consolidated net sales $ 2,841.6 $ 2,934.2 $ 8,093.2 $ 8,350.9 Three Months Ended Nine Months Ended September 30, 2019 September 30, 2018 September 30, 2019 September 30, 2018 (In millions) U.S. $ 348.3 $ 374.2 $ 1,018.7 $ 1,081.4 Canada (1) (615.5 ) 77.5 (513.3 ) 147.9 Europe (2) 77.5 96.0 105.8 152.9 International (3) (7.7 ) (1.0 ) (5.5 ) 4.0 Corporate (4) (111.2 ) (136.6 ) (332.4 ) (95.7 ) Consolidated income (loss) before income taxes $ (308.6 ) $ 410.1 $ 273.3 $ 1,290.5 (1) During the three months ended September 30, 2019, we recorded a goodwill impairment loss to our Canada reporting unit of $668.3 million , which was recorded as a special item. See Note 7, "Goodwill and Intangible Assets" for further discussion. During the three months ended June 30, 2019, we completed the sale of our existing Montreal brewery for $96.2 million (CAD 126.0 million ), resulting in a $61.3 million gain, which was recorded as a special item. Also, during the three and nine months ended September 30, 2019 , we recorded unrealized mark-to-market losses of approximately $11 million and approximately $4 million , respectively, on the HEXO Corp. ("HEXO") warrants received in connection with the formation of the Truss LP ("Truss") joint venture. Additionally, during the first quarter of 2019, we received payment and recorded a gain of $1.5 million resulting from a purchase price adjustment related to the historical sale of Molson Inc.’s ownership interest in the Montreal Canadiens, which is considered an affiliate of MCBC. (2) During the third quarter of 2019, we recorded special charges of $12.4 million resulting from the deconsolidation of the Grolsch joint venture, which were comprised primarily of impairment losses of the associated definite-lived intangible assets. See Note 4, "Investments" and Note 7, "Goodwill and Intangible Assets" for further information. (3) During the three months ended September 30, 2019 , we recorded an aggregate goodwill and definite-lived intangible asset impairment loss related to our India reporting unit of $12.2 million , which was recorded as a special item. See Note 7, "Goodwill and Intangible Assets" for further discussion. (4) During the three months ended March 31, 2018, we recorded a gain of $328.0 million related to the Adjustment Amount as defined and further discussed in Note 5, "Special Items." Additionally, related to the unrealized mark-to-market valuation on our commodity hedge positions, we recorded unrealized losses of $14.9 million and $12.0 million during the three and nine months ended September 30, 2019 , respectively, and unrealized losses of $23.2 million and $62.8 million during the three and nine months ended September 30, 2018 , respectively. Income (loss) before income taxes includes the impact of special items. Refer to Note 5, "Special Items" for further discussion.

Equity Method Investments and Joint Ventures [Abstract]
Investments	Investments Our investments include both equity method and consolidated investments. Those entities identified as VIEs have been evaluated to determine whether we are the primary beneficiary. The VIEs included under "Consolidated VIEs" below are those for which we have concluded that we are the primary beneficiary and accordingly, we have consolidated these entities. None of our consolidated VIEs held debt as of September 30, 2019 or December 31, 2018 . We have not provided any financial support to any of our VIEs during the year that we were not previously contractually obligated to provide. Amounts due to and due from our equity method investments are recorded as affiliate accounts payable and affiliate accounts receivable. Authoritative guidance related to the consolidation of VIEs requires that we continually reassess whether we are the primary beneficiary of VIEs in which we have an interest. As such, the conclusion regarding the primary beneficiary status is subject to change and we continually evaluate circumstances that could require consolidation or deconsolidation. Our consolidated VIEs are Cobra Beer Partnership, Ltd. ("Cobra U.K."), Rocky Mountain Metal Container ("RMMC"), Rocky Mountain Bottle Company ("RMBC") and Truss. Our unconsolidated VIEs are Brewers Retail Inc. ("BRI") and Brewers' Distributor Ltd. ("BDL"). Both BRI and BDL have outstanding third party debt which is guaranteed by their respective shareholders. As a result, we have a guarantee liability of $59.7 million and $35.9 million recorded as of September 30, 2019 and December 31, 2018 , respectively, which is presented within accounts payable and other current liabilities on the unaudited condensed consolidated balance sheets and represents our proportionate share of the outstanding balance of these debt instruments. The carrying value of the guarantee liability equals fair value, which considers an adjustment for our own non-performance risk and is considered a Level 2 measurement. The offset to the guarantee liability was recorded as an adjustment to our respective equity method investment within the unaudited condensed consolidated balance sheets. The resulting change in our equity method investments during the year due to movements in the guarantee represents a non-cash investing activity. Consolidated VIEs The following summarizes the assets and liabilities of our consolidated VIEs (including noncontrolling interests): As of September 30, 2019 December 31, 2018 Total Assets Total Liabilities Total Assets Total Liabilities (In millions) RMMC/RMBC $ 201.4 $ 14.4 $ 189.8 $ 35.0 Other $ 34.0 $ 7.8 $ 31.0 $ 5.1 Grolsch Deconsolidation In September 2019, we received termination notices of our Grolsch U.K. Ltd. ("Grolsch") joint venture arrangement, as well as the related brewing and distribution agreements for the Grolsch brands in the U.K. and Ireland. While we are in the process of assessing the validity of the termination notices and the Company's legal options in response thereto, the Grolsch joint venture is no longer operating as of September 30, 2019 and our production, marketing and sale of the Grolsch brands in these markets has ceased. We have reassessed our status as the primary beneficiary of the joint venture and concluded that we are no longer able to exert control over the operations or direction of the joint venture or otherwise influence the activities that most significantly impact the economics of the entity. Therefore, we have deconsolidated the joint venture and recorded an immaterial loss on deconsolidation as a special item during the third quarter of 2019. Our determination of the fair value of our retained noncontrolling investment in the joint venture, which represents a Level 3 measurement, was derived based on the fair value of the net assets of the joint venture, consisting primarily of cash. Additionally, as all operations have ceased, including our distribution of the Grolsch brands in these markets, we have recorded impairment losses related to the respective distribution agreement and brand definite-lived intangible assets. Aggregate charges recorded as special items related to the above activity totaled $12.4 million

We also recorded impairment losses related to definite-lived intangible assets in India of $6.1 million . See Note 7, "Goodwill and Intangible Assets" for further discussion. (2) Charges for the three and nine months ended September 30, 2019 and September 30, 2018 primarily consist of accelerated depreciation in excess of normal depreciation related to the closure of the Vancouver brewery, which occurred in the third quarter of 2019, and the planned closure of the Montreal brewery, which is currently expected to occur in 2021. We currently expect to incur additional charges, including estimated accelerated depreciation charges in excess of normal depreciation of approximately CAD 32 million , through final closure of the Montreal brewery. However, due to the uncertainty inherent in our estimates, these estimated future accelerated depreciation charges as well as the timing of the brewery closure are subject to change. (3) During the second quarter of 2019, we completed the sale of the existing Montreal brewery property for $96.2 million (CAD 126.0 million ) and recognized a gain of $61.3 million . See Note 1, "Basis of Presentation and Summary of Significant Accounting Policies" for further discussion. (4) During the third quarter of 2019, we recorded special charges of $12.4 million resulting from the deconsolidation of the Grolsch joint venture, which were comprised primarily of impairment losses of the associated definite-lived intangible assets. See Note 4, "Investments" and Note 7, "Goodwill and Intangible Assets" for further information. (5) During the first quarter of 2018, we received $330.0 million from ABI, of which $328.0 million constituted a purchase price adjustment (the "Adjustment Amount"), related to the Miller International Business which was acquired in our acquisition of the remaining portion of MillerCoors which occurred on October 11, 2016 . As this settlement occurred following the finalization of purchase accounting, we recorded the settlement proceeds related to the Adjustment Amount as a gain within special items, net in our unaudited condensed consolidated statement of operations in our Corporate segment and within cash provided by operating activities in our unaudited condensed consolidated statement of cash flows for the nine months ended September 30, 2018 . Restructuring Activities On October 28, 2019, as part of our revitalization plan, we made the determination to establish Chicago, Illinois as our North American operational headquarters, close our existing office in Denver, Colorado and consolidate certain administrative functions into our other existing office locations. In connection with these consolidation activities, certain impacted employees will be extended an opportunity to continue their employment with the company in the new organization and locations and, for those not continuing with the company, such employees will be asked to provide transition assistance and offered severance packages in connection with their termination of service with the company. As a result, we expect to reduce employment levels by approximately 400 to 500 employees as part of this restructuring, primarily in our existing United States, Canada and International reporting segments, as well as Corporate. The consolidation activities are expected to be substantially completed by the end of fiscal year 2021. In connection with these consolidation activities and related organizational and personnel changes, we currently expect to incur certain cash and non-cash restructuring charges related to employee relocation, severance, retention and transition costs, non-cash asset related costs, lease exit costs in connection with office leases in Denver, Colorado, and other transition activities estimated in the range of approximately $120 million to $180 million in the aggregate, the majority of which will be cash charges that will be spread through the balance of this fiscal year and fiscal years 2020 and 2021. Costs related to these restructuring activities are expected to be recorded as special items within our unaudited condensed consolidated statements of operations beginning in the fourth quarter of 2019. As we continually evaluate our cost structure and seek opportunities for further efficiencies and cost savings as part of these initiatives, we may incur additional restructuring related charges or adjustments to previously recorded charges in the future; however, we are unable to estimate the amount of charges at this time. During the third quarter of 2018, we initiated restructuring activities in the U.S. in order to align our cost base with our scale of business. As a result, we reduced U.S. employment levels by approximately 300 employees in the fourth quarter of 2018. Severance costs related to these restructuring activities were recorded as special items within our unaudited condensed consolidated statements of operations in the third quarter of 2018. The accrued restructuring balances as of September 30, 2019 below, which do not include the impacts of the above-mentioned revitalization plan, represent expected future cash payments required to satisfy the remaining severance obligations to terminated employees, the majority of which we expect to be paid in the next 12 months.

Our tax rate is volatile and may increase or decrease with changes in, among other things, the amount and source of income or loss, our ability to utilize foreign tax credits, excess tax benefits or deficiencies from share-based compensation, changes in tax laws, and the movement of liabilities established pursuant to accounting guidance for uncertain tax positions as statutes of limitations expire, positions are effectively settled, or when additional information becomes available. There are proposed or pending tax law changes in various jurisdictions and other changes to regulatory environments in countries in which we do business that, if enacted, may have an impact on our effective tax rate.

Based on foreign exchange rates as of September 30, 2019 , the estimated future amortization expense of intangible assets is as follows: Fiscal year Amount (In millions) 2019 - remaining $ 55.0 2020 $ 218.9 2021 $ 212.6 2022 $ 207.9 2023 $ 206.7 Amortization expense of intangible assets was $55.4 million and $55.8 million for the three months ended September 30, 2019 and September 30, 2018 , respectively and $166.0 million and $168.6 million for the nine months ended September 30, 2019 and September 30, 2018 , respectively. This expense is primarily presented within marketing, general and administrative expenses on the unaudited condensed consolidated statements of operations. Interim Impairment Assessment We identified a triggering event requiring an interim impairment assessment of the goodwill within our Canada reporting unit at the end of the third quarter of 2019, which resulted in a goodwill impairment loss of $668.3 million . The goodwill impairment trigger was the result of continued challenges and steepening declines within the Canadian beer industry reflected in the prolonged weakened performance of the Canada reporting unit through the third quarter of 2019. These performance headwinds have been countered, in part, by the benefit of the recent interest rate environment, which resulted in a decrease in the risk-free rate included in our current year discount rate calculations. Specifically, the discount rate used in developing our interim fair value estimate for the Canada reporting unit was 8.50% , as compared to 9.25% used as of the October 1, 2018 annual testing date. However, the performance declines and increased challenges within the beer industry in Canada, coupled with significant increases in cost inflation, volume deleverage, and resulting margin erosion, has had a material adverse impact on the expected future cash flows utilized in the valuation approaches for the Canada reporting unit, such that it was determined that the fair value of the reporting unit was more likely than not reduced below its carrying amount during the quarter. As a result of this triggering event, we performed an interim quantitative analysis, using a combination of discounted cash flow analyses and market-based approaches, consistent with our annual impairment testing, in which it was determined that the carrying value of the Canada reporting unit exceeded its fair value by $668.3 million . We also evaluated the indefinite-lived and definite-lived intangible assets within our Canada reporting unit, prior to recording the goodwill impairment, and concluded that no impairments were required; however, the Coors Light distribution agreement indefinite-lived intangible asset is considered to be at risk of future impairment. Separately, during the third quarter of 2019 we also identified an interim triggering event related to goodwill within our India reporting unit resulting from significant declines in performance in the current year, coupled with the continuation of challenging business conditions, which required us to perform an interim quantitative impairment analysis at the end of the third quarter of 2019. As a result of this interim analysis, we determined that the carrying value of the India reporting unit exceeded its fair value, resulting in an aggregate impairment loss of $12.2 million related to the goodwill of our India reporting unit and a definite-lived brand intangible asset. Annual Goodwill and Indefinite-Lived Intangible Impairment Testing We previously completed our required annual goodwill and indefinite-lived intangible impairment testing as of October 1, 2018, the first day of our fourth quarter and concluded there were no impairments of goodwill within our reporting units or our indefinite-lived intangible assets. The fair value of the U.S., Europe and Canada reporting units were estimated at approximately 19% , 11% and 6% in excess of carrying value, respectively, as of the October 1, 2018 testing date. As a result, our Europe and Canada reporting units were considered at risk of impairment following the 2018 assessment. Ultimately, the risk associated with the Canada business culminated in a triggering event related to goodwill within our Canada reporting unit in the third quarter of 2019, as discussed above. Our Europe reporting unit, which remains at risk of impairment, did not have a triggering event identified during the third quarter and, along with our U.S. reporting unit and other indefinite-lived intangible assets, will be tested for impairment as of October 1, 2019, the first day of our fourth quarter. Key Assumptions Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions and factors. The key assumptions used to derive the estimated fair values of our reporting units and indefinite-lived intangibles are discussed above as well as in Part II—Item 8 Financial Statements, Note 10, "Goodwill and Intangible Assets" in our Annual Report, and represent level 3 measurements. Based on known facts and circumstances, we evaluate and consider recent events and uncertain items, as well as related potential implications, as part of our annual and interim assessments and incorporate into the analyses as appropriate. These facts and circumstances are subject to change and may impact future analyses. For example, we continue to monitor the challenges within the beer industry for further weakening or additional systemic structural declines. Separately, the Ontario government adopted a bill that, if enacted, could adversely impact the existing terms of the beer distribution and retail systems in the province, as further described in Note 12, "Commitments and Contingencies." This alone or in combination with the potential realization of further weakened performance within the Canada reporting unit, beyond that considered in our assessments, could have a material adverse impact on the underlying cash flow assumptions used in developing our Canada reporting unit fair value estimates for the purpose of goodwill and indefinite-lived intangible asset impairment testing, which could result in a further goodwill impairment, or an impairment of our Coors Light distribution agreement indefinite-lived intangible asset in Canada. While historical performance and current expectations have resulted in fair values of our U.S. and Europe reporting units and our indefinite-lived intangible assets in excess of carrying values, if our assumptions are not realized, it is possible that an impairment loss may need to be recorded in the future. Definite-Lived Intangibles Regarding definite-lived intangibles, we continuously monitor the performance of the underlying assets for potential triggering events suggesting an impairment review should be performed. With the exception of the impairment losses related to the Grolsch brand and distribution agreement definite-lived intangible assets discussed in Note 4, "Investments" and the brand intangible asset related to our India business discussed above, no such triggering events were identified in the first three quarters of 2019

(2) As of September 30, 2019 , we have cross currency swaps in order to hedge a portion of the foreign currency translational impacts of our European investment. As a result of the swaps, we have economically converted our $500 million 2.25% notes due 2020 and a portion of our $1.0 billion 2.1% senior notes due 2021 and associated interest to EUR denominated, which result in EUR interest rates to be received of 0.68% and 0.71% , respectively. See Note 11, "Derivative Instruments and Hedging Activities" for further details. (3) As of January 1, 2019 , we reclassified approximately $3 million and $82 million of short-term and long-term finance lease liabilities from accounts payable and other current liabilities and other non-current liabilities to current portion of long-term debt and short-term borrowings and long-term debt, respectively, in connection with our adoption of the new lease accounting standard. See Note 2, "New Accounting Pronouncements" for further details. (4) During the first three quarters of 2019, we used proceeds from the issuance of commercial paper to partially fund the repayment of our notes upon maturity. As of September 30, 2019 , the outstanding borrowings under our commercial paper program had a weighted-average effective interest rate and tenor of 2.37% and 9 days, respectively. (5) As of September 30, 2019 , we had $1.6 million in bank overdrafts and $92.3 million in bank cash related to our cross-border, cross-currency cash pool, for a net positive position of $90.7 million . As of December 31, 2018 , we had $1.1 million in bank overdrafts and $88.9 million in bank cash related to our cross-border, cross-currency cash pool for a net positive position of $87.8 million . We had total outstanding borrowings of $5.6 million and $7.3 million under our two JPY overdraft facilities as of September 30, 2019 and December 31, 2018 , respectively. In addition, we have USD, CAD and GBP lines of credit under which we had no borrowings as of September 30, 2019 or December 31, 2018 . Debt Fair Value Measurements We utilize market approaches to estimate the fair value of certain outstanding borrowings by discounting anticipated future cash flows derived from the contractual terms of the obligations and observable market interest and foreign exchange rates. As of September 30, 2019 and December 31, 2018 , the fair value of our outstanding long-term debt (including the current portion of long-term debt) was approximately $9.2 billion and $9.9 billion , respectively. All senior notes are valued based on significant observable inputs and classified as Level 2 in the fair value hierarchy. The carrying values of all other outstanding long-term borrowings and our short-term borrowings approximate their fair values and are also classified as Level 2 in the fair value hierarchy. Revolving Credit Facility and Commercial Paper Program As of September 30, 2019 , we had $1.2 billion available to draw on our $1.5 billion revolving credit facility, as the borrowing capacity is reduced by borrowings under our commercial paper program. During the third quarter of 2019, we extended the maturity date of our revolving credit facility by one year to July 7, 2024. We had no borrowings drawn on this revolving credit facility as of December 31, 2018 . The maximum leverage ratio, as defined by the revolving credit facility agreement, is 4.75x net debt to EBITDA, with a decline to 4.00x net debt to EBITDA as of the last day of the fiscal quarter ending December 31, 2020. Under the terms of each of our debt facilities, we must comply with certain restrictions. These include customary events of default and specified representations, warranties and covenants, as well as covenants that restrict our ability to incur certain additional priority indebtedness (certain thresholds of secured consolidated net tangible assets), certain leverage threshold percentages, create or permit liens on assets, and restrictions on mergers, acquisitions, and certain types of sale lease-back transactions. As of September 30, 2019 , we were in compliance with all of these restrictions and have met all debt payment obligations. All of our outstanding senior notes as of September 30, 2019

Specifically, the unrealized gain (loss) on outstanding net investment hedge positions was historically presented within the "Gain (loss) on derivative instruments" column of this table. Once settled, the realized gain (loss) was reclassified to be presented within the "Foreign currency translation adjustments" column. We have retrospectively adjusted this table to present all activity associated with net investment hedge positions within the "Foreign currency translation adjustments" column, along with other insignificant presentational reclassifications. These presentational changes had no net impact on the aggregate AOCI balance, and did not impact the unaudited condensed consolidated statements of comprehensive income for any period presented. Reclassifications from AOCI to net income (loss) were immaterial for the three and nine months ended September 30, 2019 and September 30, 2018 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities Our risk management and derivative accounting policies are presented within Part II—Item 8 Financial Statements, Note 1, "Basis of Presentation and Summary of Significant Accounting Policies" and Note 16, "Derivative Instruments and Hedging Activities" in our Annual Report and did not significantly change during the first three quarters of 2019 . As noted in Note 16 of the Notes included in our Annual Report, due to the nature of our counterparty agreements, and the fact that we are not subject to master netting arrangements, we are not able to net positions with the same counterparty and, therefore, present our derivative positions on a gross basis in our unaudited condensed consolidated balance sheets. Except as noted below, our significant derivative positions have not changed considerably since year-end. Cross Currency Swaps Effective March 20, 2019, we entered into cross currency swap agreements having a total notional value of approximately EUR 353 million ( $400 million upon execution) in order to hedge a portion of the foreign currency translational impacts of our European investment. As a result of the swaps, we economically converted a portion of our $1.0 billion 2.1% senior notes due 2021 and associated interest to EUR denominated, which resulted in a EUR interest rate to be received at 0.71% . Separately, effective April 3, 2019, we voluntarily early terminated our $500 million cross currency swaps due in 2020 under which we were receiving EUR interest payments at a rate of 0.85% , and concurrently entered into new cross currency swap agreements having a total notional of approximately EUR 445 million ( $500 million upon execution) in order to hedge a portion of the foreign currency translation impacts of our European investment. As a result of the swaps, we economically converted our $500 million 2.25% senior notes due 2020 and associated interest to EUR denominated, which will result in a EUR interest rate to be received of 0.68% . The termination of the original $500 million cross currency swaps resulted in cash receipts of approximately $47 million which were classified as investing activities in our unaudited condensed consolidated statement of cash flows during the second quarter of 2019. We have designated each of these cross currency swaps as net investment hedges and accordingly, record changes in fair value due to fluctuations in the spot rate to AOCI. The changes in fair value of the swaps attributable to changes other than those due to fluctuations in the spot rate are excluded from the assessment of hedge effectiveness and recorded to interest expense over the life of the hedge. Derivative Fair Value Measurements We utilize market approaches to estimate the fair value of our derivative instruments by discounting anticipated future cash flows derived from the derivative's contractual terms and observable market interest, foreign exchange and commodity rates. The fair values of our derivatives also include credit risk adjustments to account for our counterparties' credit risk, as well as our own non-performance risk, as appropriate. The fair value of our warrants to acquire common shares of HEXO at a strike price of CAD 6.00 per share are estimated using the Black-Scholes option-pricing model. As of September 30, 2019 and December 31, 2018 , respectively, the assumptions used to estimate the fair value of the HEXO warrants are as follows: As of September 30, 2019 As of December 31, 2018 Expected term (years) 2.0 2.8 Estimated volatility 74.39 % 88.71 % Risk-free interest rate 1.56 % 2.04 % Expected dividend yield — % — % The expected term is based on the contractual maturity date of the warrants. Estimated volatility is based on a blend of implied volatility and historical volatility of HEXO's stock. The risk-free rate utilized is based on a zero-coupon Canadian Treasury security yield with a remaining term equal to the expected term of the warrants. The expected dividend yield is determined by historical dividend levels. The table below summarizes our derivative assets and liabilities that were measured at fair value as of September 30, 2019 and December 31, 2018 .

As of September 30, 2019 we expect our reclassification of AOCI into earnings related to cash flow hedges to be immaterial over the next 12 months as our expected net losses primarily offset our expected net gains. For derivatives designated in cash flow hedge relationships, the maximum length of time over which forecasted transactions are hedged as of September 30, 2019 is approximately 4 years, as well as those related to our forecasted debt issuances in 2021, 2022, and 2026.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation and Other Disputes and Environmental Related to litigation, other disputes and environmental issues, we have an aggregate accrued contingent liability of $16.7 million and $13.7 million as of September 30, 2019 and December 31, 2018 , respectively. While we cannot predict the eventual aggregate cost for litigation, other disputes and environmental matters in which we are currently involved, we believe adequate reserves have been provided for losses that are probable and estimable. Additionally, as noted below, there are certain loss contingencies that we deem reasonably possible for which a range of loss is not estimable at this time; for all other matters, we believe that any reasonably possible losses in excess of the amounts accrued are immaterial to our unaudited condensed consolidated interim financial statements. Our litigation, other disputes and environmental issues are discussed in further detail within Part II—Item 8 Financial Statements, Note 18, "Commitments and Contingencies" in our Annual Report and did not significantly change during the first three quarters of 2019 , except as noted below. Other than those disclosed below, we are also involved in other disputes and legal actions arising in the ordinary course of our business. While it is not feasible to predict or determine the outcome of these proceedings, in our opinion, based on a review with legal counsel, other than as noted, none of these disputes or legal actions are expected to have a material impact on our business, consolidated financial position, results of operations or cash flows. However, litigation is subject to inherent uncertainties and an adverse result in these or other matters may arise from time to time that may harm our business. On February 12, 2018, Stone Brewing Company filed a trademark infringement lawsuit in federal court in the Southern District of California against MillerCoors LLC alleging that the Keystone brand has “rebranded” itself as “Stone” and is marketing itself in a manner confusingly similar to Stone Brewing Company's registered Stone trademark. Stone Brewing Company seeks treble damages in the amount of MillerCoors’ profit from Keystone sales. MillerCoors subsequently filed an answer and counterclaims against Stone Brewing Company. On May 31, 2018, Stone Brewing Company filed a motion to dismiss MillerCoors' counterclaims and for a preliminary injunction seeking to bar MillerCoors from continuing to use “STONE” on Keystone Light cans and related marketing materials. In March 2019, the court denied Stone Brewing Company’s motion for preliminary injunction and its motion to dismiss MillerCoors’ counterclaims. No trial date has been scheduled. We intend to vigorously assert and defend our rights in this lawsuit. A range of potential loss is not estimable at this time. In December 2018, the U.S. Department of Treasury issued a regulation that impacts our ability to claim a refund of certain federal duties, taxes, and fees paid for beer sold between the U.S. and certain other countries effective in February 2019. As a result, future claims will no longer be accepted, and we may be further unable to collect historically claimed, but not yet received, refunds of approximately $40 million , which are recorded within other non-current assets on our unaudited condensed consolidated balance sheet as of September 30, 2019 . On February 15, 2019, two purported stockholders filed substantially similar putative class action complaints against the Company, Mark R. Hunter, and Tracey I. Joubert (the “Defendants”) in the United States District Court for the District of Colorado (the “Colorado District Court”), and in the United States District Court for the Northern District of Illinois (the “Illinois District Court”). On February 21, 2019, another purported stockholder filed a substantially similar complaint in the Colorado District Court. The plaintiffs purport to represent a class of the Company’s stockholders and assert that the Defendants violated Sections 10(b) and 20(a) of the Exchange Act by allegedly making false and misleading statements or omissions regarding the Company’s restatement of consolidated financial statements for the years ended December 31, 2016 and December 31, 2017, and that the Company purportedly lacked adequate internal controls over financial reporting. The plaintiffs seek, among other things, an unspecified amount of damages and reasonable attorneys’ fees, expert fees and other costs. On April 16, 2019, motions to consolidate and appoint a lead plaintiff were filed in each case. On May 24, 2019, the securities class action suit filed with the Illinois District Court was transferred to the Colorado District Court, but was voluntarily dismissed on July 25, 2019. On October 2, 2019, the class action lawsuits originally filed in Colorado District Court were consolidated, and, on October 3, 2019, the court appointed a lead plaintiff and lead counsel for the consolidated case. On October 11, 2019, the parties filed a joint motion to enter a schedule for filing an amended complaint and anticipated motion to dismiss. We intend to defend the claims vigorously. A range of potential loss is not estimable at this time. On March 26, 2019, a purported stockholder filed a purported shareholder derivative action in Colorado District Court against the Company’s board of directors and certain officers (the “Individual Defendants”), and the Company as a nominal defendant. On May 14, 2019, another purported stockholder filed a substantially similar complaint in the Colorado District Court. On August 12, 2019, a third derivative complaint was filed in Colorado District Court by a purported stockholder. All three derivative complaints assert claims against the Individual Defendants for breaches of fiduciary duty and unjust enrichment arising out of the Company’s dissemination to shareholders of purportedly materially misleading and inaccurate information in connection with the Company’s restatement of consolidated financial statements for the years ended December 31, 2016 and December 31, 2017. The complaints further allege that the Company lacked adequate internal controls over financial reporting. The third derivative complaint filed in August also alleges the Individual Defendants violated Sections 14(a) and 20(a) of the Exchange Act by issuing misleading statements in the Company’s proxy statement. The relief sought in the complaints include changes to the Company’s corporate governance procedures, unspecified damages, restitution, and attorneys’ fees, expert fees, other costs and such other relief as the court deems proper. The parties have agreed to stay the proceedings in the shareholder derivative actions until the federal district courts rule on anticipated motions to dismiss in the above mentioned consolidated securities action. All three derivative actions have been administratively closed, subject to being reopened for good cause shown. A range of potential loss is not estimable at this time. In June 2019, the Ontario government adopted a bill that, if enacted, would terminate a 10-year Master Framework Agreement that was originally signed between the previous government administration and MCBC, Labatt Brewing Company Limited, Sleeman Breweries Ltd., and Brewers Retail Inc. in 2015 and dictates the terms of the beer distribution and retail systems in Ontario through 2025. The government has not yet proclaimed the bill as law. The impacts of these potential legislative changes are unknown at this time, but could have a negative impact on the results of operations, cash flows and financial position of the Canada segment. While discussions remain ongoing with the government to reach a mutually agreeable alternative to the enactment of the law, the Company and the other Master Framework Agreement signatories are prepared to vigorously defend their rights and pursue legal recourse, should the Master Framework Agreement be unilaterally terminated by the enactment of the legislation. Guarantees and Indemnities We guarantee indebtedness and other obligations to banks and other third parties for some of our equity method investments and consolidated subsidiaries. As of September 30, 2019 and December 31, 2018 , the unaudited condensed consolidated balance sheets include liabilities related to these guarantees of $59.7 million and $35.9 million , respectively. See Note 4, "Investments" for further detail. Separately, related to our Kaiser indemnities, we have accrued $13.7 million and $14.7 million , in aggregate, as of September 30, 2019 and December 31, 2018 , respectively. The maximum potential claims amount remaining for the Kaiser-related purchased tax credits was $84.2 million , based on foreign exchange rates as of September 30, 2019 . Our Kaiser liabilities are discussed in further detail within Part II—Item 8 Financial Statements, Note 18, "Commitments and Contingencies" in our Annual Report and did not significantly change during the first three quarters of 2019 .

During the three months ended June 30, 2019, we completed the sale of our existing Montreal brewery for $96.2 million (CAD 126.0 million ), resulting in a $61.3 million gain, which was recorded as a special item. Also, during the three and nine months ended September 30, 2019 , we recorded unrealized mark-to-market losses of approximately $11 million and approximately $4 million , respectively, on the HEXO Corp. ("HEXO") warrants received in connection with the formation of the Truss LP ("Truss") joint venture. Additionally, during the first quarter of 2019, we received payment and recorded a gain of $1.5 million resulting from a purchase price adjustment related to the historical sale of Molson Inc.’s ownership interest in the Montreal Canadiens, which is considered an affiliate of MCBC. (2) During the third quarter of 2019, we recorded special charges of $12.4 million resulting from the deconsolidation of the Grolsch joint venture, which were comprised primarily of impairment losses of the associated definite-lived intangible assets.

We also recorded impairment losses related to definite-lived intangible assets in India of $6.1 million . See Note 7, "Goodwill and Intangible Assets" for further discussion. (2) Charges for the three and nine months ended September 30, 2019 and September 30, 2018 primarily consist of accelerated depreciation in excess of normal depreciation related to the closure of the Vancouver brewery, which occurred in the third quarter of 2019, and the planned closure of the Montreal brewery, which is currently expected to occur in 2021. We currently expect to incur additional charges, including estimated accelerated depreciation charges in excess of normal depreciation of approximately CAD 32 million , through final closure of the Montreal brewery. However, due to the uncertainty inherent in our estimates, these estimated future accelerated depreciation charges as well as the timing of the brewery closure are subject to change. (3) During the second quarter of 2019, we completed the sale of the existing Montreal brewery property for $96.2 million (CAD 126.0 million ) and recognized a gain of $61.3 million . See Note 1, "Basis of Presentation and Summary of Significant Accounting Policies" for further discussion. (4) During the third quarter of 2019, we recorded special charges of $12.4 million resulting from the deconsolidation of the Grolsch joint venture, which were comprised primarily of impairment losses of the associated definite-lived intangible assets. See Note 4, "Investments" and Note 7, "Goodwill and Intangible Assets" for further information.

Schedule of Derivative Assets and Liabilities at Fair Value	The fair value of our warrants to acquire common shares of HEXO at a strike price of CAD 6.00 per share are estimated using the Black-Scholes option-pricing model. As of September 30, 2019 and December 31, 2018 , respectively, the assumptions used to estimate the fair value of the HEXO warrants are as follows: As of September 30, 2019 As of December 31, 2018 Expected term (years) 2.0 2.8 Estimated volatility 74.39 % 88.71 % Risk-free interest rate 1.56 % 2.04 % Expected dividend yield — % — % The expected term is based on the contractual maturity date of the warrants. Estimated volatility is based on a blend of implied volatility and historical volatility of HEXO's stock. The risk-free rate utilized is based on a zero-coupon Canadian Treasury security yield with a remaining term equal to the expected term of the warrants. The expected dividend yield is determined by historical dividend levels. The table below summarizes our derivative assets and liabilities that were measured at fair value as of September 30, 2019 and December 31, 2018 .
