This report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). From time to time, we may also provide oral or written forward-looking statements in other materials we release to the public. Such forward-looking statements are subject to the safe harbor created by the Private Securities Litigation Reform Act of 1995.

Statements that refer to projections of our future financial performance, anticipated trends in our businesses, and other characterizations of future events or circumstances are forward-looking statements, and include, but are not limited to, statements under the headings "Management's Discussion and Analysis of Financial Condition and Results of Operations," and under the heading "Outlook for 2018" therein, relating to overall volume trends, consumer preferences, pricing trends, industry forces, cost reduction strategies, anticipated results, anticipated synergies, anticipated tax rates and benefits, expectations for funding future capital expenditures and operations, expectations regarding future dividends, debt service capabilities, timing and amounts of debt and leverage levels, shipment levels and profitability, market share and the sufficiency of capital resources. In addition, statements that we make in this report that are not statements of historical fact may also be forward-looking statements. Words such as "expects," "goals," "plans," "believes," "continues," "may," "anticipate," "seek," "estimate," "outlook," "trends," "future benefits," "potential," "projects," "strategies," and variations of such words and similar expressions are intended to identify forward-looking statements.

Forward-looking statements are subject to risks and uncertainties that could cause actual results to be materially different from those indicated (both favorably and unfavorably). These risks and uncertainties include, but are not limited to those described under the heading "Risk Factors," elsewhere throughout this report, and those described from time to time in our past and future reports filed with the SEC, including in our Annual Report on Form 10-K for the year ended December 31, 2017. Caution should be taken not to place undue reliance on any such forward-looking statements. Forward-looking statements speak only as of the date when made and we undertake no obligation to update any forward-looking statement, whether as a result of new information, future events or otherwise.

Our historical unaudited condensed consolidated financial statements have been revised to reflect the retrospective application of our change in accounting policy for calculating the market-related value of pension plan assets used to determine net periodic pension cost as discussed in our Annual Report.

The results of operations for the three and six months ended June 30, 2018, are not necessarily indicative of the results that may be achieved for the full year.

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" and Note 5, "Share-Based Payments" for further discussion. We also had non-cash activities related to capital expenditures incurred but not yet paid, and the recognition of capital leases. These non-cash activities are excluded from our unaudited condensed consolidated statements of cash flows and were $153.0 million and $163.1 million for the six months ended June 30, 2018, and June 30, 2017, respectively.

Discontinued Operations

We no longer present the activity related to foreign exchange movements nor the liabilities associated with our indemnities resulting from the historical sale of the Kaiser business (as discussed in Note 19 of the Notes included in our Annual Report) within discontinued operations and have accordingly reclassified the activity into other income within continuing operations of the unaudited condensed consolidated statements of operations, and the liabilities into other current and long-term liabilities within the unaudited condensed consolidated balance sheets. This change has been applied retrospectively and prospectively. As a result, we reclassified a foreign exchange gain from discontinued operations to other income (expense), net of $1.6 million and $1.0 million for the three and six months ended June 30, 2017.

Revenue Recognition

We account for revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers, which we adopted on January 1, 2018, using the modified retrospective transition approach (see Note 2, "New Accounting Pronouncements" for impacts of adoption).

Our net sales represent the sale of beer and other malt beverages (including adjacencies, such as cider and hard soda), net of excise tax. Sales are stated net of incentives, discounts and returns. Sales of products are for cash or otherwise agreed upon credit terms. Our payment terms vary by location and customer, however, the time period between when revenue is recognized and when payment is due is not significant. Our revenue generating activities have a single performance obligation and are recognized at the point in time when control transfers and our obligation has been fulfilled, which is when the related goods are shipped or delivered to the customer, depending upon the method of distribution and shipping terms. Where our products are sold under consignment arrangements, revenue is not recognized until control has transferred, which is when the product is sold to the end customer. Revenue is measured as the amount of consideration we expect to receive in exchange for the sale of our product. The cost of various programs, such as price promotions, rebates and coupons are treated as a reduction of sales. In certain of our markets, we make cash payments to customers such as slotting or listing fees, or payments for other marketing or promotional activities. These cash payments are recorded as a reduction of revenue unless we receive a distinct good or service as defined under ASC 606. Specifically, a good or service is considered distinct when it is separately identifiable from other promises in the contract, we receive a benefit from the good or service, and the benefit is separable from the sale of our product to the customer.

Certain payments made to customers are conditional on the achievement of volume targets, marketing commitments, or both. If paid in advance, we record such payments as prepayments and amortize them over the relevant period to which the customer commitment is made (generally up to five years). When the payment is not for a distinct good or service, or fair value cannot be reasonably estimated, the amortization of the prepayment or the cost as incurred is recorded as a reduction of revenue. Where a distinct good or service is received and fair value can be reasonably estimated, the cost is included as marketing, general and administrative expenses. The amounts deferred are reassessed regularly for recoverability over the contract period and are impaired where there is objective evidence that the benefits will not be realized or the asset is otherwise not recoverable. Separately, as discussed below, we analyze whether these advance payments contain a significant financing component for potential adjustment to the transaction price.

Our primary revenue generating activity represents the sale of beer and other malt beverages to customers, including both domestic and exported product sales. Our customer could be a distributor, retail or on-premise outlet, depending on the market. The majority of our revenues are generated from brands that we own and brew ourselves, however, we also import or brew and sell certain non-owned partner brands under licensing and related arrangements. In addition, primarily in the U.K., as well as certain other countries in our Europe segment, we sell other beverage companies' products to on-premise customers to provide them with a full range of products for their retail outlets. We refer to this as the "factored brand business." Sales from this business are included in our net sales and cost of goods sold when ultimately sold. In the factored brand business, we normally purchase inventory, which includes excise taxes charged by the vendor, take orders from customers for such brands, negotiate with the customers on pricing and invoice customers for the product and related costs of delivery. In addition, we incur the risk of loss at times we are in possession of the inventory and for the receivables due from the customers. Revenues for owned brands, partner and imported brands, as well as factored brands are recognized at the point in time when control is transferred to the customer as discussed above.

Other Revenue Generating Activities

We contract manufacture for other brewers in some of our markets. These contractual agreements require us to brew, package and ship certain brands to these brewers, who then sell the products to their own customers in their respective markets. Revenues under contract brewing arrangements are recognized when our obligation related to the finished product is fulfilled and control of the product transfers to these other brewers.

We also have licensing agreements with third party partners who brew and distribute our products in various markets across our segments. Under these agreements, we are compensated based on the amount of products sold by our partners in these markets at an agreed upon royalty rate or profit percentage. We apply the sales-based royalty practical expedient to these licensing arrangements and recognize revenue as product is sold by our partners at the agreed upon rate.

We have evaluated these other revenue generating activities under the disaggregation disclosure criteria outlined within the guidance and concluded that these other revenue generating activities are immaterial for separate disclosure. See Note 3, "Segment Reporting", for disclosure of revenues by geographic segment.

11

Variable Consideration

Our revenue generating activities include variable consideration which is recorded as a reduction of the transaction price based upon expected amounts at the time revenue for the corresponding product sale is recognized. For example, customer promotional discount programs are entered into with certain distributors for certain periods of time. The amount ultimately reimbursed to distributors is determined based upon agreed-upon promotional discounts which are applied to distributors' sales to retailers. Other common forms of variable consideration include volume rebates for meeting established sales targets, and coupons and mail-in rebates offered to the end consumer. The determination of the reduction of the transaction price for variable consideration requires that we make certain estimates and assumptions that affect the timing and amounts of revenue and liabilities recorded. We estimate this variable consideration, including analyzing for a potential constraint on variable consideration, by taking into account factors such as the nature of the promotional activity, historical information and current trends, availability of actual results, and expectations of customer and consumer behavior.

We do not have standard terms that permit return of product; however, in certain markets where returns occur we estimate the amount of returns as variable consideration based on historical return experience and adjust our revenue accordingly. Products that do not meet our high quality standards are returned by the customer or recalled and destroyed and are recorded as a reduction of revenue. The reversal of revenue is recorded upon determination that the product will be recalled and destroyed. We estimate the costs required to facilitate product returns and record them in cost of goods sold as required.

During the three and six months ended June 30, 2018, adjustments to revenue from performance obligations satisfied in the prior period due to changes in estimates in variable consideration were immaterial.

Significant Financing Component and Costs to Obtain Contracts

In certain of our businesses where such practices are legally permitted, we make loans or advanced payments to retail outlets that sell our brands. For arrangements that do not span greater than one year, we apply the practical expedient available under ASC 606 and do not adjust the transaction price for the effects of a potential significant financing component. We further analyze arrangements that span greater than one year on an ongoing basis to determine whether a significant financing component exists. No such arrangements existed during the six months ended June 30, 2018.

Advance payments to customers, where legally permitted, are deferred and amortized as a reduction to revenue over the expected period of benefit and tested for recoverability as appropriate. All other costs to obtain contracts and fulfill are expensed as incurred based on the nature, significance and expected benefit of these costs relative to the contract.

Contract Assets and Liabilities

We continually evaluate whether our revenue generating activities and advanced payment arrangements with customers result in the recognition of contract assets or liabilities. No such assets or liabilities existed as of June 30, 2018, or December 31, 2017. Separately, trade accounts receivable, including affiliate receivables, approximates receivables from contracts with customers.

Shipping and Handling

Freight costs billed to customers for shipping and handling are recorded as revenue. Shipping and handling expense related to costs incurred to deliver product are recognized within cost of goods sold. We account for shipping and handling activities that occur after control has transferred as a fulfillment cost as opposed to a separate performance obligation, and the costs of shipping and handling are recognized concurrently with the related revenue.

Excise Tax

Excise tax remitted to tax authorities are government-imposed excise taxes on beer. Excise taxes are shown in a separate line item in the unaudited condensed consolidated statements of operations as a reduction of sales. Excise taxes are recognized as a current liability within accounts payable and other current liabilities on the unaudited condensed consolidated balance sheets, with the liability subsequently reduced when the taxes are remitted to the tax authority.

Net Periodic Pension Cost Revised Accounting Policy

The following table presents the impacts to our quarterly information resulting from the retrospective application of our change in accounting policy for calculating the market-related value of pension plan assets used to determine net periodic pension cost effective in the fourth quarter of 2017 as discussed in Note 1 of the Notes of our Annual Report. The below "As Adjusted" amounts have been further adjusted to reflect the adoption of the accounting standard on the presentation of net periodic pension and postretirement benefit cost. See Note 2, "New Accounting Pronouncements".

2. New Accounting Pronouncements

New Accounting Pronouncements Recently Adopted

Pension and Other Postretirement Benefit Plans

In March 2017, the FASB issued authoritative guidance intended to improve the consistency, transparency and usefulness of financial information related to defined benefit pension or other postretirement plans. Under the new guidance, an employer must disaggregate the service cost component from the other components of net benefit cost within the statements of operations. Specifically, the new guidance requires us to report only the service cost component in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period; while the other components of net benefit cost are now presented in the unaudited condensed consolidated statements of operations separately from the service cost component and outside of operating income. The amendments in this update also allow only the service cost component to be eligible for capitalization when applicable. We have also determined that only service cost will be reported within each operating segment and all other components will be reported within the Corporate segment. The guidance related to the income statement presentation of service costs and other pension and postretirement benefit costs is applied retrospectively, while the capitalization of service costs component is applied prospectively. We adopted this guidance as of January 1, 2018, which was a classification adjustment only and had no impact to our consolidated net income. The adoption of this guidance resulted in the following retrospective adjustments within our unaudited condensed consolidated results of operations:

(1) As discussed in detail within Note 1, "Basis of Presentation and Summary of Significant Accounting Policies", our historical unaudited condensed consolidated financial statements have been revised to reflect the retrospective application of our change in accounting policy for calculating the market-related value of pension plan assets used to determine net periodic pension cost. The change was effective in the fourth quarter of 2017.

Revenue Recognition

In May 2014, the FASB issued authoritative guidance related to new accounting requirements for the recognition of revenue from contracts with customers. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for the goods or services.

We adopted this guidance and related amendments as of January 1, 2018, applying the modified retrospective transition approach to all contracts. Based on our comprehensive assessment of the new guidance, including our evaluation of the five-step approach outlined within the guidance, we concluded that the adoption did not have a significant impact to our core revenue generating activities. However, the adoption resulted in a change in presentation of certain cash payments made to customers as well as the timing of recognition of certain promotional discounts. Specifically, certain cash payments to customers were previously recorded within marketing, general and administrative expenses in the unaudited condensed consolidated statements of operations. Upon the adoption of the new guidance, many of these cash payments did not meet the specific criteria within the new guidance of providing a “distinct” good or service, and therefore, were required to be presented as a reduction of revenue. Based on foreign exchange rates as of June 30, 2018, we currently anticipate that the impact of this change will result in a reduction of both revenue and marketing, general and administrative expenses by approximately $60 million to $70 million during 2018, primarily within our Canada segment, with no impact to full year net income. However, actual results may differ from these estimates. Furthermore, upon adoption of the new guidance, certain of our promotional discounts which are deemed variable consideration under the new guidance, are now recognized at the time of the related shipment of product, which is earlier than recognized under historical guidance. We anticipate that this change in recognition timing will shift financial statement recognition primarily amongst quarters, however, do not anticipate that the full-year impact will be significant to our financial results. We also evaluated the requirements of the new guidance on our other revenue generating activities such as contract brewing and license arrangements, and concluded that no changes to our historical accounting treatment was required.

15

As a result of the cumulative impact of adopting the new guidance, we recorded a reduction to opening retained earnings of $27.8 million as of January 1, 2018, with an offsetting increase primarily within accounts payable and other current liabilities and the related tax effects, related primarily to the accelerated recognition of certain promotional discounts. Results for reporting periods beginning after January 1, 2018, are presented under the new guidance, while prior period amounts have not been adjusted and continue to be reported in accordance with historical accounting guidance. The following tables provide a comparison of our current period results of operations and financial position under the new guidance, versus our financial statements if the historical guidance had continued to be applied:

These changes are primarily driven by the reclassification of certain cash payments to customers from marketing, general and administrative expenses to a reduction of revenue, as well as the change in the timing of recognition of certain promotional discounts and cash payments to customers. This adoption 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 further details on our significant accounting policies for revenue recognition pursuant to the new guidance.

Financial and Commodity Risks

In August 2017, the FASB issued authoritative guidance intended to refine and expand hedge accounting for both financial and commodity risks. The revised guidance will create more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes. In addition, this guidance makes certain targeted improvements to simplify the application of hedge accounting guidance. This guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted. We have elected to early adopt this guidance during the second quarter of 2018. All transition requirements have been applied to hedging relationships existing on the date of adoption and the effect of the adoption is reflected as of January 1, 2018. The adoption of this guidance did not result in a cumulative adjustment to the opening balance of retained earnings as of January 1, 2018, and did not have any other material effect on our results of operations, financial position or cash flows. All required disclosures under the new guidance have been made in Note 12, "Derivative Instruments and Hedging Activities".

New Accounting Pronouncements Not Yet Adopted

In February 2018, the FASB issued authoritative guidance intended to improve the usefulness of financial information related to the enactment of the 2017 U.S. Tax Cuts and Jobs Act (the "2017 Tax Act"). This guidance provides an option to reclassify from accumulated other comprehensive income 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. This guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted. We are currently evaluating the potential impact on our financial statements in order to determine whether to elect to make this reclassification upon adoption of this guidance.

In February 2016, the FASB issued authoritative guidance intended to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing key information about leasing arrangements. Under the new guidance, lessees will be required to recognize a right-of-use asset and a lease liability, measured on a discounted basis, at the commencement date for all leases with terms greater than twelve months. Additionally, this guidance will require disclosures to help investors and other financial statement users to better understand the amount, timing, and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements. This guidance is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted. The guidance should be applied under a modified retrospective transition approach, with an option to apply the guidance either at the beginning of the earliest comparative period presented in the adoption-period financial statements, or to apply the new guidance at the adoption date. We currently anticipate that we will apply the guidance at the beginning of the period of adoption; however, this expectation may change following the completion of our evaluation of the impact of this guidance on our financial statements. We are currently evaluating the potential impact on our financial position and results of operations upon adoption of this guidance. This guidance will result in our existing operating leases, for certain real estate and equipment, to be recognized on our balance sheet. We will further analyze our lease arrangements as we complete our assessment and implementation of this new guidance.

Other than the items noted above, there have been no new accounting pronouncements not yet effective or adopted in the current year that we believe have a significant impact, or potential significant impact, to our unaudited condensed consolidated interim financial statements.

3. 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 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 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 are now reported within each operating segment, as discussed in Note 2, "New Accounting Pronouncements", and all other components are reported, retrospectively and prospectively, within the Corporate segment in accordance with how our chief operating decision maker evaluates the performance of our business.

No single customer accounted for more than 10% of our consolidated sales for the three and six months ended June 30, 2018, or June 30, 2017. 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 in consolidation and are primarily related to U.S. segment sales to the other segments.

The following tables present net sales, income (loss) before income taxes and total assets by segment:

(1) Segment results for the three and six months ended June 30, 2017, have been adjusted to reflect the adoption of the new accounting pronouncement for pension and other postretirement benefit costs as well as the reclassification of all non-service cost components of pension and other postretirement costs to Corporate. See Note 2, "New Accounting Pronouncements" for further details.

(2) During the first quarter of 2017, we received payment and recorded a gain of CAD 10.6 million, or $8.1 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.

(3) During the three months ended March 31, 2017, we recorded a provision for an estimate of uncollectible receivables of approximately$11 millionrelated to Agrokor, a large customer in Croatia. We have subsequently reduced this exposure and as of June 30, 2018, our estimated provision of uncollectible receivables from Agrokor totals approximately $4 million. The settlement plan related to this matter was announced in July 2018. We are currently evaluating the implications of the settlement plan, and do not expect it to have a significant impact on our financial statements upon finalization.Separately, during the first quarter of 2017, we released an indirect tax loss contingency, which was initially recorded in the fourth quarter of 2016, for a benefit of approximately$50 million. See Note 14, "Commitments and Contingencies" for details.

(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 6, "Special Items". Additionally, related to the unrealized mark-to-market valuation on our commodity hedge positions, we recorded an unrealized gain of $45.1 million and an unrealized loss of $39.6 million during the three and six months ended June 30, 2018, respectively, compared to an unrealized loss of $23.4 million and an unrealized gain of $39.7 million during the three and six months ended June 30, 2017, respectively.

Income (loss) before income taxes includes the impact of special items. Refer to Note 6, "Special Items" for further discussion.

4. 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, consolidate these entities. None of our consolidated VIEs held debt as of June 30, 2018, or December 31, 2017. 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. As of June 30, 2018, and December 31, 2017, our consolidated VIEs were Cobra Beer Partnership, Ltd. ("Cobra U.K."), Grolsch U.K. Ltd. ("Grolsch"), Rocky Mountain Metal Container ("RMMC") and Rocky Mountain Bottle Company ("RMBC"). 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 $55.4 million and $38.1 million recorded as of June 30, 2018, and December 31, 2017, 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):

5. Share-Based Payments

We have one share-based compensation plan, the MCBC Incentive Compensation Plan (the "Incentive Compensation Plan"), as of June 30, 2018, and all outstanding awards fall under this plan. During the three and six months endedJune 30, 2018, and June 30, 2017, we recognized share-based compensation expense related to the following Class B common stock awards to certain directors, officers and other eligible employees, pursuant to the Incentive Compensation Plan: RSUs, DSUs, PSUs and stock options.

As of June 30, 2018, there was $73.3 million of total unrecognized compensation expense from all share-based compensation arrangements granted under the Incentive Compensation Plan, related to unvested awards. This total compensation expense is expected to be recognized over a weighted-average period of 2.1 years.

The total intrinsic values of stock options and SOSARs exercised during the six months endedJune 30, 2018, and June 30, 2017, were $5.1 million and $5.3 million, respectively. During the six months endedJune 30, 2018, and June 30, 2017, cash received from stock option exercises was $6.3 million and $1.1 million, respectively, and total tax benefits realized, including excess tax benefits, from share-based awards vested or exercised was $5.9 million and $19.2 million, respectively.

The fair value of each option granted in the first half of 2018 and 2017 was determined on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:

	Six Months Ended
	June 30, 2018	June 30, 2017
Risk-free interest rate	2.65%	2.04%
Dividend yield	2.08%	1.64%
Volatility range	22.36%-24.14%	22.40%-22.88%
Weighted-average volatility	22.81%	22.52%
Expected term (years)	5.3	5.1
Weighted-average fair market value	$15.44	$18.66

20

The risk-free interest rates utilized for periods throughout the contractual life of the stock options are based on a zero-coupon U.S. Treasury security yield at the time of grant. Expected volatility is based on a combination of historical and implied volatility of our stock. The expected term of stock options is estimated based upon observations of historical employee option exercise patterns and trends of those employees granted options in the respective year.

The fair value of the market metric for each PSU granted in the first half of 2018 and 2017 was determined on the date of grant using a Monte Carlo model to simulate total stockholder return for MCBC and peer companies with the following weighted-average assumptions:

	Six Months Ended
	June 30, 2018	June 30, 2017
Risk-free interest rate	2.34%	1.59%
Dividend yield	2.08%	1.64%
Volatility range	13.03%-81.87%	13.71%-80.59%
Weighted-average volatility	22.76%	24.24%
Expected term (years)	2.8	2.8
Weighted-average fair market value	$78.30	$97.13

The risk-free interest rates utilized for periods throughout the expected term of the PSUs are based on a zero-coupon U.S. Treasury security yield at the time of grant. Expected volatility is based on historical volatility of our stock as well as the stock of our peer firms, as shown within the volatility range above, for a period from the grant date consistent with the expected term. The expected term of PSUs is calculated based on the grant date to the end of the performance period.

As of June 30, 2018, there were 3.4 million shares of the Company's Class B common stock available for issuance as awards under the Incentive Compensation Plan.

6. Special Items

We have incurred charges or realized benefits that either we do not believe to be indicative of our core operations, or we believe are significant to our current operating results warranting separate classification. As such, we have separately classified these charges (benefits) as special items.

(1) Charges for the three and six months ended June 30, 2018, relate to the planned closure of the Colfax, California cidery, and consist primarily of accelerated depreciation in excess of normal depreciation. Charges for the three and six months ended June 30, 2017, relate to the closure of the Eden, North Carolina, brewery.

(2) For the three and six months ended June 30, 2018, we incurred charges consisting primarily of accelerated depreciation in excess of normal depreciation related to the planned closures of the Vancouver and Montreal breweries, which are currently expected to occur in 2019 and 2021, respectively. Charges for the three and six months ended June 30, 2017, relate primarily to accelerated depreciation in excess of normal depreciation related to the above mentioned planned closure of the Vancouver brewery.

21

(3) For the three and six months ended June 30, 2018, we incurred charges primarily related to the closure of the Burton South brewery, which closed during the first quarter of 2018. For the three and six months ended June 30, 2017, we incurred charges consisting primarily of accelerated depreciation in excess of normal depreciation related to the Burton South brewery closure.

(4) For the three and six months ended June 30, 2018, we incurred charges related to the exit of our China business.

(5) On October 11, 2016, we completed the Acquisition for $12.0 billion in cash, subject to a downward adjustment as described in the purchase agreement. This purchase price "Adjustment Amount," as defined in the purchase agreement, required payment to MCBC if the unaudited EBITDA for the Miller International Business for the twelve months prior to closing was below $70 million.

Throughout the process outlined in the purchase agreement, significant uncertainty remained on the ultimate outcome of the Adjustment Amount. As a result, no adjustment to purchase accounting was made through the completion of the measurement period in October 2017. Subsequently, on January 21, 2018, MCBC and ABI entered into a settlement agreement related to the purchase price adjustment under the purchase agreement, and on January 26, 2018, pursuant to the settlement agreement, ABI paid to MCBC $330.0 million, of which $328.0 million constitutes the Adjustment Amount. 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 within our unaudited condensed consolidated statement of cash flows for the six months ended June 30, 2018. MCBC and ABI also agreed to certain mutual releases as further described in the settlement agreement which was filed as an exhibit to a Current Report on Form 8-K filed January 22, 2018.

Restructuring Activities

Beginning in 2016, restructuring initiatives related to the integration of MillerCoors after the completion of the Acquisition were implemented in order to operate a more efficient business and achieve cost saving targets which to-date resulted in reduced employment levels by approximately 106 employees. Total restructuring costs related to integration initiatives represent the majority of the charges within the table below by segment. Severance costs related to these restructuring activities were recorded as special items within our unaudited condensed consolidated statements of operations. 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 in the future, however, we are unable to estimate the amount of charges at this time.

We have continued our ongoing assessment of our supply chain strategies across our segments in order to align with our cost saving objectives. As part of this strategic review, which began in 2014, we have had restructuring activities related to the closure or planned closure of breweries, as well as activities related to business efficiencies. As a result, we have reduced employment levels by a total of 450 employees. Consequently, we recognized severance and other employee-related charges, which we have recorded as special items within our unaudited condensed consolidated statements of operations. We will continue to evaluate our supply chain network and seek opportunities for further efficiencies and cost savings, and we therefore 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.

The accrued restructuring balances 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.

7. Income Tax

	Three Months Ended				Six Months Ended
	June 30, 2018		June 30, 2017		June 30, 2018		June 30, 2017
Effective tax rate	18	%	27	%	19	%	26	%

The decrease in the effective tax rate during the second quarter and first half of 2018 versus 2017, is primarily driven by the reduction of the statutory U.S. federal corporate income tax rate from 35% to 21% as a result of the 2017 Tax Act. Our effective tax rates were also affected by the impact of discrete items. Specifically, we recognized a net discrete tax benefit of $1.2 million during the second quarter of 2018, and net discrete tax expense of $4.3 million during the first half of 2018. During the second quarter and first half of 2017, we recognized a net discrete tax benefit of $1.3 million and $9.7 million, respectively.

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.

Additionally, we continue to evaluate the impacts of the 2017 Tax Act. As we further understand its implications, as well as the related, and yet to be issued, regulations and interpretations, our effective tax rate could be impacted. For example, subsequent to the enactment, the FASB staff concluded that companies should make an accounting policy election to account for the tax effects of the global intangible low-taxed income (“GILTI”) either as a component of income tax expense in the future period the tax arises, or as a component of deferred taxes on the related investments in foreign subsidiaries. We are currently evaluating the GILTI provisions of the 2017 Tax Act and the related implications and have not finalized our accounting policy election, however, have preliminarily concluded that we will record as a periodic expense as incurred, and therefore, have not recorded deferred taxes for GILTI. We will continue to evaluate in future periods and will finalize our accounting policy election at that time.

We did not make any material adjustments to the amounts recorded as of December 31, 2017, as a result of the 2017 Tax Act, however, we continue to consider these amounts provisional for the reasons discussed above. Additional impacts from the 2017 Tax Act will be recorded as they are identified during the measurement period pursuant to SEC Staff Accounting Bulletin No. 118 ("SAB 118"). Our determination of the tax effects of the 2017 Tax Act will be completed no later than one year from the enactment date as permitted under SAB 118. Any adjustments to provisional amounts that are identified during the measurement period will be recorded and disclosed in the reporting period in which the adjustment is determined. The complexity of the 2017 Tax Act could necessitate the need to use the full one year measurement period to adequately interpret, analyze and conclude upon the tax effects of the 2017 Tax Act as of the enactment date.

(1) During the first quarter of 2018, we completed the acquisition of Aspall Cyder Limited, an established premium cider business in the U.K. As part of the preliminary purchase price accounting in the first quarter of 2018, goodwill generated in conjunction with this acquisition has been recorded within our Europe segment, subject to normal purchase accounting adjustments.

(2) During the second quarter of 2018, we recorded adjustments to the preliminary purchase price allocation related to our acquisition of Le Trou du Diable, which was completed in the fourth quarter of 2017.

The following table presents details of our intangible assets, other than goodwill, as of June 30, 2018:

Total		$	14,958.8	$	(662.3	)	$	14,296.5

The changes in the gross carrying amounts of intangibles from December 31, 2017, to June 30, 2018, are primarily driven by the impact of foreign exchange rates, as a significant amount of intangibles are denominated in foreign currencies.

24

Based on foreign exchange rates as of June 30, 2018, the estimated future amortization expense of intangible assets is as follows:

Fiscal year	Amount
	(In millions)
2018 - remaining	$	111.5
2019	$	222.8
2020	$	221.8
2021	$	215.5
2022	$	210.9

Amortization expense of intangible assets was $56.2 million and $55.1 million for the three months endedJune 30, 2018, and June 30, 2017, respectively, and $112.8 million and $110.3 million for the six months ended June 30, 2018, and June 30, 2017, respectively. This expense is primarily presented within marketing, general and administrative expenses on the unaudited condensed consolidated statements of operations.

Annual Goodwill Impairment Testing

We completed our required annual goodwill and indefinite-lived intangible impairment testing as of October 1, 2017, 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.

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 in Part II—Item 8 Financial Statements, Note 11, "Goodwill and Intangible Assets" in our Annual Report.

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 assessment and incorporate into the analyses as appropriate. These facts and circumstances are subject to change and may impact future analyses. For example, subsequent to the completion of our annual impairment testing, we considered the implications of the enactment of the 2017 Tax Act on our U.S. reporting unit and indefinite-lived brand valuations. The results of our preliminary analysis indicated that the implications are expected to be favorable, keeping all other assumptions constant.

While historical performance and current expectations have resulted in fair values of our reporting units and indefinite-lived intangible assets in excess of carrying values, if our assumptions are not realized, it is possible that an impairment charge may need to be recorded in the future.

Indefinite and Definite-Lived Intangibles

Regarding indefinite and definite-lived intangibles, we continuously monitor the performance of the underlying assets for potential triggering events suggesting an impairment review should be performed. No such triggering events were identified in the first half of 2018 that resulted in an impairment.

(1) The fair value hedges related to these notes have been settled and are being amortized over the life of the respective note.

(2) During the second quarter, we entered into 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 economically converted our $500 million2.25% senior notes due 2020 and associated interest to EUR denominated, which will result in a EUR interest rate to be received at 0.85%. See Note 12, "Derivative Instruments and Hedging Activities" for further details.

(3) As of June 30, 2018, we had $6.9 million in bank overdrafts and $71.6 million in bank cash related to our cross-border, cross-currency cash pool, for a net positive position of $64.7 million. As of December 31, 2017, we had $1.2 million in bank overdrafts and $37.8 million in bank cash related to our cross-border, cross-currency cash pool for a net positive position of $36.6 million. We had total outstanding borrowings of $5.4 million and $3.2 million under our two JPY overdraft facilities as of June 30, 2018, and December 31, 2017, respectively. In addition, we have GBP and CAD lines of credit under which we had no borrowings as of June 30, 2018, or December 31, 2017.

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 June 30, 2018, and December 31, 2017, the fair value of our outstanding long-term debt (including the current portion of long-term debt) was approximately $10.5 billion and $11.2 billion, respectively. All senior notes are valued based on

26

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

As of June 30, 2018, we had $1.5 billion available to draw under our $1.5 billion revolving multi-currency credit facility. The borrowing capacity is reduced by borrowings under our commercial paper program when outstanding. We had no borrowings drawn on this revolving credit facility as of June 30, 2018. The maximum leverage ratio of this facility is 5.25x debt to EBITDA, with a decline to 4.00x debt to EBITDA as of the last day of the fiscal quarter ending December 31, 2020. Subsequent to quarter end, we extended the maturity date of our revolving credit facility by one year to July 7, 2023.

Under the terms of each of our debt facilities, we must comply with certain restrictions. These include customary events of default and specified representations and warranties and covenants, including, among other things, covenants that restrict our ability to incur certain additional priority indebtedness, create or permit liens on assets, or engage in mergers or consolidations. As of June 30, 2018, we were in compliance with all of these restrictions and have met all debt payment obligations. All of our outstanding senior notes as of June 30, 2018, rank pari-passu.

12. Derivative Instruments and Hedging Activities

Our risk management and derivative accounting policies are presented in Notes 1 and 17 of the Notes included in our Annual Report and did not significantly change during the first half of 2018, with the exception of early adopting the updated hedge accounting guidance during the second quarter of 2018. The adoption of this guidance did not result in a cumulative adjustment to the opening balance of retained earnings as of January 1, 2018, and did not have any other material effect on our results of operations, financial position or cash flows. All required disclosures under the new guidance are presented below on a prospective basis. See further discussion in Note 2, "New Accounting Pronouncements". As noted in Note 17 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 April 18, 2018, we entered into cross currency swap agreements having a total notional of approximately EUR 404 million ($500.0 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 our $500 million2.25% senior notes due 2020 and associated interest to EUR denominated, which will result in a EUR interest rate to be received at 0.85%. We have designated these cross currency swaps as net investment hedges and accordingly, record changes in fair value due to fluctuations in the

28

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.

Forward Starting Interest Rate Swaps

Forward starting interest rate swaps are instruments we use to manage our exposure to the volatility of the interest rates associated with future interest payments on a forecasted debt issuance. Subsequent to June 30, 2018, we entered into forward starting interest rate swaps with notional amounts totaling $1.5 billion. The forward starting interest rate swaps have an effective date of July 2018 and termination dates of July 2021, May 2022 and July 2026, mirroring the terms of the forecasted debt issuances. Under the agreements we are required to early terminate these swaps at the time we expect to issue the related forecasted debt. We have designated these contracts as cash flow hedges. As a result, the unrealized mark-to-market gains or losses will be recorded to AOCI until termination at which point the realized gain or loss of these swaps at issuance of the hedged debt will be reclassified from AOCI and amortized to interest expense over the term of the hedged debt.

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 table below summarizes our derivative assets and liabilities that were measured at fair value as of June 30, 2018, and December 31, 2017.

We expect net losses of approximately $1 million (pretax) recorded in AOCI as of June 30, 2018, related to cash flow hedges, will be reclassified into earnings within the next 12 months. For derivatives designated in cash flow hedge relationships, the maximum length of time over which forecasted transactions are hedged as of June 30, 2018, is approximately four years.

During the six months endedJune 30, 2018, employer contributions to the defined benefit pension plans were approximately $5 million. Total 2018 employer contributions to the defined benefit plans are expected to be approximately $10 million, based on foreign exchange rates as of June 30, 2018. BRI and BDL contributions to their defined benefit pension plans are not included above, as they are not consolidated in our financial statements.

Additionally, we have adopted the FASB's new guidance related to defined benefit pension and other postretirement plans. Specifically, the new guidance requires us to report only the service cost component in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period; while the other components of net benefit cost are now presented in the unaudited condensed consolidated statements of operations separately from the service cost component and outside of operating income.We have also determined that only service cost will be reported within each operating segment and all other components will be reported within the Corporate segment. See further discussion in Note 2, "New Accounting Pronouncements".

14. Commitments and Contingencies

Litigation, Environmental and Other Contingencies

Related to litigation, environmental issues and other contingencies, we had $13.9 million and $17.8 million accrued, in aggregate, as of June 30, 2018, and December 31, 2017, respectively. While we cannot predict the eventual aggregate cost for legal, environmental and other matters in which we are currently involved, we believe adequate reserves have been provided for losses that are probable and estimable. Additionally, we believe that any reasonably possible losses in excess of the amounts accrued are immaterial to our unaudited condensed consolidated interim financial statements. Our legal, environmental and other liabilities are discussed in further detail within Part II—Item 8 Financial Statements, Note 19, "Commitments and Contingencies" in our Annual Report and did not significantly change during the first half of 2018.

We are 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.

As a result of receiving a favorable ruling related to our historical indirect tax calculations in Europe, we released a previously recorded indirect tax provision related to our Europe operations during the first quarter of 2017, resulting in a benefit of approximately $50 million, recorded within the excise taxes line item on the unaudited condensed consolidated statement of operations during the quarter ended March 31, 2017. During the second quarter of 2017, we received formal confirmation from the regulatory authority that they would not appeal the local jurisdictional court ruling, and the regulatory authority has since withdrawn its assessments. As a result, we believe this dispute is fully resolved.

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

35

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 motions to dismiss and for a preliminary injunction seeking to bar MillerCoors from continuing to use “STONE” on Keystone Light cans and related marketing materials. A hearing relating to the motions to dismiss and preliminary injunction is currently scheduled during the third quarter of 2018. We intend to vigorously assert and defend our rights in this lawsuit. A range of potential loss is not estimable at this time.

Guarantees

We guarantee indebtedness and other obligations to banks and other third parties for some of our equity method investments and consolidated subsidiaries. As of June 30, 2018, and December 31, 2017, the unaudited condensed consolidated balance sheets include liabilities related to these guarantees of $59.8 million and $42.8 million, respectively, primarily related to the guarantee of the indebtedness of our equity method investments. See Note 4, "Investments" for further detail.

Separately, related to our Kaiser indemnities, we have accrued $14.7 million and $17.3 million, in aggregate, as of June 30, 2018, and December 31, 2017, respectively. The maximum potential claims amount remaining for the Kaiser-related purchased tax credits was $90.3 million, based on foreign exchange rates as of June 30, 2018. Our Kaiser liabilities are discussed in further detail within Part II—Item 8 Financial Statements, Note 19, "Commitments and Contingencies" in our Annual Report and did not significantly change during the first half of 2018.

15. Supplemental Guarantor Information

For purposes of this Note 15, including the tables, "Parent Issuer" shall mean MCBC. "Subsidiary Guarantors" shall mean certain Canadian and U.S. subsidiaries reflecting the substantial operations of each of our Canada and U.S. segments.

SEC Registered Securities

On May 3, 2012, MCBC issued $1.9 billion of senior notes, in a registered public offering, consisting of $300 million2.0% senior notes due 2017 (subsequently repaid in the second quarter of 2017), $500 million3.5% senior notes due 2022, and $1.1 billion5.0% senior notes due 2042. Additionally, on July 7, 2016, MCBC issued $500 million1.45% senior notes due 2019, $1.0 billion2.10% senior notes due 2021, $2.0 billion3.0% senior notes due 2026, $1.8 billion4.2% senior notes due 2046 and EUR $800.0 million1.25% senior notes due 2024, in a registered public offering. In December 2017, MCBC completed an exchange offer in which it issued publicly registered senior notes in exchange for its $500 million1.90% senior notes due 2019, $500 million2.25% senior notes due 2020 and our EUR 500 million floating rate senior notes due 2019, which were issued in private placement transactions in March 2017. "Parent Issuer" in the below tables is specifically referring to MCBC in its capacity as the issuer of these 2012, 2016 and 2017 issuances. These senior notes are guaranteed on a senior unsecured basis by the Subsidiary Guarantors. Each of the Subsidiary Guarantors is 100% owned by the Parent Issuer. The guarantees are full and unconditional and joint and several.

None of our other outstanding debt is registered with the SEC, and such other outstanding debt is guaranteed on a senior unsecured basis by the Parent and/or Subsidiary Guarantors. These guarantees are full and unconditional and joint and several. See Note 9, "Debt" for details of all debt issued and outstanding as of June 30, 2018.

Presentation

Certain amounts have been revised to reflect the retrospective application of our change in accounting policy and the new accounting pronouncements recently adopted as discussed in Note 1, "Basis of Presentation and Summary of Significant Accounting Policies" and Note 2, "New Accounting Pronouncements".

Effective January 1, 2018, MillerCoors USA LLC, a new entity with no historic activity, was added as a subsidiary guarantor. In addition, effective December 26, 2017, our historical subsidiary guarantor, Jacob Leinenkugel Brewing Co., LLC, was merged with and into the existing subsidiary guarantor, MillerCoors LLC, and, on January 1, 2018, our historical subsidiary guarantors MillerCoors Holdings LLC and MC Holding Company LLC were also merged with and into MillerCoors LLC, a subsidiary guarantor.

In the first quarter of 2018, MillerCoors LLC, a subsidiary guarantor, declared a distribution of approximately $1.7 billion to Molson Coors Brewing Company, which was simultaneously non-cash settled via offset to an equal amount of payables that were owed by Molson Coors Brewing Company to MillerCoors LLC.

The following information sets forth the unaudited condensed consolidating statements of operations for the three and six months ended June 30, 2018, and June 30, 2017, unaudited condensed consolidating balance sheets as of June 30, 2018, and

36

December 31, 2017, and unaudited condensed consolidating statements of cash flows for the six months endedJune 30, 2018, and June 30, 2017. Investments in subsidiaries are accounted for under the equity method; accordingly, entries necessary to consolidate the Parent Issuer and all of our guarantor and non-guarantor subsidiaries are reflected in the eliminations column. In the opinion of management, separate complete financial statements of MCBC and the Subsidiary Guarantors would not provide additional material information that would be useful in assessing their financial composition.

ITEM 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") in this Form 10-Q is provided as a supplement to, and should be read in conjunction with, our audited consolidated financial statements, the accompanying notes and the MD&A included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 ("Annual Report"), as well as our unaudited condensed consolidated interim financial statements and the accompanying notes included in this Form 10-Q. Due to the seasonality of our operating results, quarterly financial results are not an appropriate basis from which to project annual results.

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 United States; Molson Coors Canada ("MCC" or Canada segment), operating in Canada; Molson Coors Europe (Europe segment), operating in Bulgaria, Croatia, Czech Republic, Hungary, Montenegro, Republic of Ireland, Romania, Serbia, the United Kingdom 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.

Operational Measures

We have certain operational measures, such as STWs and STRs, which we believe are important metrics. STW is a metric that we use in our U.S. business to reflect the sales from our operations to our direct customers, generally wholesalers. We believe the STW metric is important because it gives an indication of the amount of beer and adjacent products that we have produced and shipped to customers. STR is a metric that we use in our Canada and U.S. businesses to refer to sales closer to the end consumer than STWs, which generally means sales from our wholesalers or our company to retailers, who in turn sell to consumers. We believe the STR metric is important because, unlike STWs, it provides the closest indication of the performance of our brands in relation to market and competitor sales trends.

Executive Summary

We are one of the world's largest brewers and have a diverse portfolio of owned and partner brands, including global priority brands Blue Moon, Coors Banquet, Coors Light, Miller Genuine Draft, Miller Lite, and Staropramen, regional champion brands Carling, Molson Canadian and other leading country-specific brands, as well as craft and specialty beers such as Creemore Springs, Cobra, Doom Bar, Henry's Hard and Leinenkugel's. With centuries of brewing heritage, we have been crafting high-quality, innovative products with the purpose of delighting the world's beer drinkers and with the ambition to be the first choice for our consumers and customers. Our success depends on our ability to make our products available to meet a wide range of consumer segments and occasions.

Adoption of Revenue Recognition Guidance

On January 1, 2018, we adopted the FASB's new accounting pronouncement related to revenue recognition. This guidance was adopted using the modified retrospective approach, and therefore, prior period results have not been restated. The following table highlights the impact of this new guidance on summarized components of our unaudited condensed consolidated statements of operations for the three and six months ended June 30, 2018, when comparing our current period results of operations under the new guidance, versus our results of operations if historical guidance had continued to be applied.

Income (loss) before income taxes	$	(13.9	)	$	(1.6	)	$	(1.1	)	$	0.2	$	(16.4	)

These impacts are primarily driven by the reclassification of certain cash payments to customers from marketing, general and administrative expenses to a reduction of revenue, as well as a change in the timing of recognition of certain promotional discounts and cash payments to customers. See Part I—Item 1. Financial Statements, Note 1, "Basis of Presentation and Summary of Significant Accounting Policies" and Note 2, "New Accounting Pronouncements" for further discussion on the adoption of this guidance.

Adoption of Pension and Other Postretirement Benefit Guidance

On January 1, 2018, we adopted the FASB's new accounting pronouncement related to the classification of pension and other postretirement benefit costs. Specifically, the new guidance requires us to report only the service cost component in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period; while the other components of net benefit cost are now presented in the unaudited condensed consolidated statements of operations separately from the service cost component and outside of operating income. The amendments in this update also allow only the service cost component to be eligible for capitalization when applicable. We have also determined that only service cost will be reported within each operating segment and all other components will be reported within the Corporate segment. The guidance related to the income statement presentation of service costs and other pension and postretirement benefit costs is applied retrospectively, while the capitalization of service costs component is applied prospectively. This adjustment is classification only and had no impact to our consolidated net income. See Part I—Item 1. Financial Statements, Note 2, "New Accounting Pronouncements" for further details including updated historical financial information.

Summary of Consolidated Results of Operations

The following table highlights summarized components of our unaudited condensed consolidated statements of operations for the three and six months ended June 30, 2018, and June 30, 2017. See Part I-Item 1. Financial Statements for additional details of our U.S. GAAP results.

Second Quarter 2018 Financial Highlights

During the second quarter of 2018, we recognized net income attributable to MCBC of $424.1 million, or $1.96 per diluted share, representing an increase of $94.2 million versus the prior year. The increase in net income attributable to MCBC was primarily driven by unrealized mark-to-market gains on our commodity positions compared to prior year, cost savings, lower income tax expense, lower interest expense and positive net pricing, partially offset by lower financial volume, higher cost inflation and the impact of adopting the new accounting pronouncement related to revenue recognition. Net sales of approximately $3.1 billion in the second quarter of 2018 were flat compared to the prior year due to positive foreign currency impact of approximately $50 million and positive net pricing, offset by lower volume and the impact of adopting the new accounting pronouncement related to revenue recognition.

Regional financial highlights:

• In our U.S. segment, income before income taxes decreased 8.4% to $445.5 million in the second quarter of 2018, compared to the prior year primarily due to cost of goods sold inflation, the impact of lower shipment volumes, negative sales mix, the impact of adopting the new accounting pronouncement related to revenue recognition and higher depreciation expense, partially offset by higher net pricing and lower marketing, general and administrative expenses.

• In our Canada segment, income before income taxes decreased by 12.1% to $61.3 million in the second quarter of 2018, compared to the prior year, primarily due to negative sales mix and lower volumes as well as the impact of adopting the new accounting pronouncement related to revenue recognition, partially offset by lower marketing investment.

• In our Europe segment, income before income taxes increased 24.2% to $86.8 million in the second quarter of 2018, compared to the prior year, primarily driven by favorable gross profit impacts, lower marketing investments, the partial reversal of bad debt provisions, the addition of Aspall Cider business, as well as favorable foreign exchange impact. These factors were partially offset by adopting recently revised excise-tax guidelines in one of our European markets and investments in our First Choice Agenda.

• In our International segment, income before income taxes increased to $1.3 million in the second quarter of 2018, compared to a loss of $7.7 million in the prior year, primarily driven by positive net pricing, favorable sales mix, and lower marketing and integration expenses, partially offset by the loss of the Modelo brands in Japan.

See "Results of Operations" below for further analysis of our segment results.

Core brand highlights:

• Global priority brand volume decreased 4.0% in the second quarter of 2018 versus 2017, due to declines across the U.S., Canada and International partially offset by growth in Europe.

• Blue Moon Belgian White global brand volume decreased 0.8% in the second quarter of 2018 versus 2017, driven by declines in the U.S., partially offset by growth in International, Canada and Europe.

48

• Carling brand volume in Europe decreased by 2.9% during the second quarter of 2018, versus the second quarter of 2017 due to lower volumes in U.K., the brand's primary market.

• Coors global brand volume - Coors Light global brand volume decreased 6.4% during the second quarter of 2018 versus the second quarter of 2017. The overall volume decrease in the second quarter of 2018 was due to lower brand volume in the U.S., Canada and International, slightly offset by growth in Europe. Volumes in the U.S. were lower than prior year reflective of the U.S. industry premium and premium light segment performance. The declines in Canada are the result of high inventory levels in Quebec at the start of the year, along with ongoing competitive pressures in Quebec and Ontario and a continued shift in consumer preference to value brands in the West. The declines in International were the result of balancing volume with pricing in Mexico. Coors Banquet global brand volume decreased 4.8% during the second quarter of 2018 versus the second quarter of 2017 driven by the U.S. and Canada.

• Miller global brand volume - Miller Lite global brand volumes decreased 3.3% during the second quarter of 2018 versus prior year, primarily driven by the U.S. However, Miller Lite gained share of the U.S. premium light segment for the fifteenth consecutive quarter. Miller Genuine Draft global brand volumedecreased 3.2% during the second quarter of 2018 versus prior year, due to the U.S. and Europe, partially offset by growth in International and Canada.

• Molson Canadian brand volume in Canada decreased by 9.2% during the second quarter of 2018 versus the prior year, primarily driven by competitive pressures in the West and Ontario.

• Staropramen global brand volume, including royalty volume, increased 10.2% during the second quarter of 2018, versus the second quarter of 2017, driven by higher volumes in European markets outside of Czech Republic, the brand's primary market.

Worldwide Brand Volume

Worldwide brand volume (or "brand volume" when discussed by segment) reflects owned brands sold to unrelated external customers within our geographic markets, net of returns and allowances, royalty volume, an adjustment from STWs to STRs calculated consistently with MCBC owned volume. Contract brewing and wholesaler volume is removed from worldwide brand volume as this is non-owned volume for which we do not directly control performance. We believe this definition of worldwide brand volume more closely aligns with how we measure the performance of our owned brands within the markets in which they are sold. Financial volume represents owned brands sold to unrelated external customers within our geographical markets, net of returns and allowances as well as contract brewing, wholesale non-owned brand volume and company-owned distribution volume. Royalty volume consists of our brands produced and sold by third parties under various license and contract-brewing agreements and because this is owned volume, it is included in worldwide brand volume. The adjustment from STWs to STRs provides the closest indication of the performance of our owned brands in relation to market and competitor sales trends, as it reflects sales volume one step closer to the end consumer and generally means sales from our wholesalers or our company to retailers.

Effective in the first quarter of 2018, we have revised our net sales per hectoliter performance discussions to include a brand volume basis as defined above with the net sales revenue component reflecting owned and actively managed brands as well as royalty revenue consistent with how management views the business. We continue to also discuss net sales per hectoliter performance on a reported basis.

Our worldwide brand volume decreased 2.4% and 2.7% during the three and six months ended June 30, 2018, compared to prior year primarily due to declines in the U.S.

Income taxes

	Three Months Ended				Six Months Ended
	June 30, 2018		June 30, 2017		June 30, 2018		June 30, 2017
Effective tax rate	18	%	27	%	19	%	26	%

The decrease in the effective tax rate during the second quarter and first half of 2018 versus 2017, was primarily driven by the reduction of the statutory U.S. federal corporate income tax rate from 35% to 21% as a result of the 2017 U.S. Tax Cuts and Jobs Act (the "2017 Tax Act"). Our effective tax rates were also affected by the impact of discrete items. Specifically, we recognized a net discrete tax benefit of $1.2 million during the second quarter of 2018, and net discrete tax expense of $4.3 million during the first half of 2018. During the second quarter and first half of 2017, we recognized a net discrete tax benefit of $1.3 million and $9.7 million, respectively.

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. Additionally, we continue to evaluate the impacts of the 2017 Tax Act. As we further understand its implications, as well as the related, and yet to be issued, regulations and interpretations, our effective tax rate could be impacted.

Refer to Part I - Item 1. Financial Statements, Note 7, "Income Tax" for additional details regarding our effective tax rate as well as our ongoing evaluation of the 2017 Tax Act and its related impacts.

Significant events

The volatility of aluminum (inclusive of Midwest Premium) and freight and fuel costs have continued to significantly impact our results during the first half of 2018. To the extent these prices continue to fluctuate, our business and financial results could be materially adversely impacted. We continue to monitor these risks and rely on our risk management hedging program to help mitigate price risk exposure for commodities including aluminum and fuel.

In order to increase overall operating efficiency, during the first quarter of 2018, the U.S. segment announced plans to close the Colfax, California cidery with the planned closure effective December 2018. Cider production will move to the 10th Street Brewery in Milwaukee, Wisconsin. Total special charges associated with the cidery closure are expected to be approximately $6 million, consisting primarily of accelerated depreciation in excess of normal depreciation and will be recorded through completion of the closure.

Volume and net sales

Brand volume for the three and six months ended June 30, 2018, declined 4.8% and 4.3%, respectively, compared to prior year, driven by lower volume in the premium light segment. STWs, excluding contract brewing volume, decreased 3.6% and 5.0% in the three and six months ended June 30, 2018, respectively, reflective of brand volume performance and year-to-date negative impacts resulting from lower distributor inventory levels, which was compounded by the launch of our new ordering system at the Golden, Colorado brewery in the first quarter.

Net sales per hectoliter on a brand volume basis for the three and six months ended June 30, 2018, increased 0.9% and 1.0%, respectively, compared to prior year due to favorable net pricing, partially offset by negative sales mix and impacts resulting from the adoption of the new accounting pronouncement related to revenue recognition. Net sales per hectoliter on a reported basis increased 1.4% and 1.2%, respectively, compared to prior year.

51

Cost of goods sold

Cost of goods sold per hectoliter for the three and six months ended June 30, 2018, increased 5.5% and 4.5%, respectively, compared to prior year driven by higher freight and fuel costs, aluminum inflation and volume deleverage, partially offset by cost savings. Additionally, for the three and six months ended June 30, 2018, we recorded $0.9 million and $2.0 million, respectively, of integration costs related to the Acquisition within cost of goods sold, and for the three and six months ended June 30, 2017, we recorded $0.7 million and $1.2 million, respectively, of integration costs related to the Acquisition within cost of goods sold.

Marketing, general and administrative expenses

Marketing, general and administrative expenses for the three and six months ended June 30, 2018, decreased compared to prior year due to spending optimization and efficiencies as well as lower employee-related expenses. Marketing, general and administrative expenses also include integration costs related to the Acquisition of $0.1 million and $4.1 million for the three and six months ended June 30, 2017, respectively.

Foreign currency impact on results

During the three months ended June 30, 2018, the CAD appreciated versus the USD on an average basis, resulting in an increase of $1.3 million to our USD earnings before income taxes. During the six months ended June 30, 2018, the CAD also appreciated versus the USD on an average basis, resulting in an increase of $1.0 million to our USD earnings before income taxes. Included in this amount are both translational and transactional impacts of changes in foreign exchange rates. The impact of transactional foreign currency gains and losses is recorded within other income (expense) in our unaudited condensed consolidated statements of operations.

Volume and net sales

Our Canada brand volume decreased 2.4% and 2.8% during the three and six months ended June 30, 2018, respectively, versus prior year, as a result of volume challenges particularly in the West and Ontario.

Our net sales per hectoliter on a brand volume basis decreased 4.5% and 3.9% in local currency during the three and six months ended June 30, 2018, respectively, compared to prior year, driven by the impacts resulting from the adoption of the new accounting pronouncement related to revenue recognition, which requires certain cash payments to customers to now be recognized as a reduction of revenue versus marketing, general and administrative expense, and negative brand mix. The

52

decrease in the three months ended June 30, 2018, was also partially offset by higher net pricing. Net sales per hectoliter on a reported basis in local currency decreased 4.1% and 3.3%, respectively, compared to prior year.

Cost of goods sold

Cost of goods sold per hectoliter in local currency decreased 0.7% and increased 1.2% during the three and six months ended June 30, 2018, respectively, versus prior year. The decrease for the three months ended June 30, 2018, was driven by cost savings and certain one-time distribution savings. The increase for the six months ended June 30, 2018, was driven by impacts of mix shift, volume deleverage, input cost inflation and foreign exchange fluctuations, partially offset by cost savings.

Marketing, general and administrative expenses

Our marketing, general and administrative expenses decreased 13.8% and 16.4% in local currency for the three and six months ended June 30, 2018, respectively, compared to prior year, primarily driven by impacts resulting from the adoption of the new accounting pronouncement related to revenue recognition as further discussed above and lower brand investments. For the three months ended, this decrease was also partially offset by year-over-year differences in the phasing of brand investments.

Other income (expense), net

During the first quarter of 2017, we received payment and recorded a gain of CAD 10.6 million, or $8.1 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.

Significant events

In January 2018, the Europe segment completed the acquisition of Aspall Cyder Limited, an established premium cider business in the U.K.

During the three months ended March 31, 2017, we recorded a provision for an estimate of uncollectible receivables of approximately$11 millionrelated to Agrokor, a large customer in Croatia. We have subsequently reduced this exposure and as

53

of June 30, 2018, our estimated provision of uncollectible receivables from Agrokor totals approximately $4 million. The settlement plan related to this matter was announced in July 2018. We are currently evaluating the implications of the settlement plan, and do not expect it to have a significant impact on our financial statements upon finalization.Separately, during the first quarter of 2017, we released an indirect tax loss contingency, which was initially recorded in the fourth quarter of 2016, for a benefit of approximately$50 million.

Foreign currency impact on results

Our Europe segment operates in numerous countries within Europe and each country's operations utilize distinct currencies. Foreign currency movements favorably impacted our Europe USD income before income taxes by $3.7 million for the three months ended June 30, 2018, and unfavorably impacted our Europe USD income before income taxes by $0.9 million for the six months ended June 30, 2018. Included in this amount are both translational and transactional impacts of changes in foreign exchange rates. The impact of transactional foreign currency gains and losses is recorded within other income (expense) in our unaudited condensed consolidated statements of operations.

Volume and net sales

Our Europe brand volume increased 2.9% and 1.8% for the three and six months ended June 30, 2018, respectively, compared to prior year, primarily driven by growth from our above premium brands and national champion brands, as well as World Cup consumption.

Net sales per hectoliter on a brand volume basis increased in local currency by 1.5% for the three months ended June 30, 2018 and decreased in local currency by 6.9% for the six months ended June 30, 2018, compared to prior year. The increase for the three months ended June 30, 2018, was primarily driven by positive sales mix and pricing. This was partially offset by adopting recently revised excise-tax guidelines in one of our European markets as well as increasing our investment behind our First Choice Agenda this year, while the decrease for the six months ended June 30, 2018, was also negatively impacted by cycling the release of the approximate $50 million indirect tax provision in the first quarter of 2017. Net sales per hectoliter on a reported basis in local currency increased 1.3% and decreased 5.4%, respectively, compared to prior year.

Cost of goods sold

Cost of goods sold per hectoliter increased 1.5% and 2.0% in local currency in the three and six months ended June 30, 2018, respectively, versus prior year, primarily due to mix shift to higher-cost brands and geographies, input inflation and logistics costs.

Marketing, general and administrative expenses

Marketing, general and administrative expenses decreased 3.5% and 6.8% in local currency in the three and six months ended June 30, 2018, respectively, compared to prior year, driven by lower marketing investments, the impact of adopting the new revenue recognition guidance and a benefit from the partial reversal of bad debt provisions, slightly offset by the addition of Aspall brand investments.

Foreign currency impact on results

Our International segment operates in numerous countries around the world and each country's operations utilize distinct currencies. Foreign currency movements did not significantly impact our International segment's USD income before income taxes for the three and six months ended June 30, 2018.

Volume and net sales

Our International brand volume increased by 0.6% and decreased 2.9% in the three and six months ended June 30, 2018, respectively, compared to prior year, primarily driven by organic volume growth in many of our focus markets, partially offset by the loss of the Modelo contract in Japan at the end of the second quarter of 2017. Brand volume for the six months ended June 30, 2018, was also negatively impacted by lower volumes in Mexico due to higher net pricing.

Net sales per hectoliter on a brand volume basis increased 3.8% and 1.8% in the three and six months ended June 30, 2018, respectively, compared to prior year. The increase for the three and six months ended June 30, 2018, was driven by positive net pricing and favorable sales mix. Net sales per hectoliter on a reported basis increased 5.3% compared to the prior year for the three months ended June 30, 2018, driven by positive net pricing and favorable sales mix. Net sales per hectoliter on a reported basis was flat compared to the prior year for the six months ended June 30, 2018.

Cost of goods sold

Cost of goods sold per hectoliter decreased 6.9% and 4.5% in the three and six months ended June 30, 2018, respectively, compared to prior year, primarily driven by sales mix changes.

Marketing, general and administrative expenses

Marketing, general and administrative expenses decreased in the three and six months ended June 30, 2018, compared to prior year, primarily due to lower marketing investments and integration costs and $2.0 million of settlement proceeds related to our Colombia business in the first quarter.

Cost of goods sold

The unrealized changes in fair value on our commodity swaps, which are economic hedges, are recorded as cost of goods sold within our Corporate business activities. As the exposure we are managing is realized, we reclassify the gain or loss to the segment in which the underlying exposure resides, allowing our segments to realize the economic effects of the derivative without the resulting unrealized mark-to-market volatility. Higher commodity market prices relative to our hedged positions on our commodity swaps drove the total unrealized mark-to-market gain of $45.1 million recognized in cost of goods sold for the three months ended June 30, 2018, as compared to the unrealized mark-to-market loss of $23.4 million recognized in cost of goods sold for the three months ended June 30, 2017. Lower commodity market prices relative to our hedged positions on our commodity swaps drove the total unrealized mark-to-market loss of $39.6 million recognized in cost of goods sold for the six months ended June 30, 2018, as compared to the unrealized mark-to-market gain of $39.7 million recognized in cost of goods sold for the six months ended June 30, 2017.

Marketing, general and administrative expenses

Marketing, general and administrative expenses decreased in the three months ended June 30, 2018, primarily due to the timing of corporate general and administrative costs and higher integration costs related to the Acquisition recognized in the prior year. The increase in the six months ended June 30, 2018, was partially offset by incremental investment behind global business capabilities including information technology investments. Specifically, for the three and six months ended June 30, 2018, we recorded integration costs related to the Acquisition of $7.7 million and $16.5 million, respectively, within marketing, general and administrative expense. For the three and six months ended June 30, 2017, we recorded integration costs related to the Acquisition of $11.2 million and $24.6 million, respectively, within marketing, general and administrative expense.

56

Interest expense, net

Net interest expense decreased for the three and six months ended June 30, 2018, compared to the prior year, primarily driven by debt repayments. See Part I—Item 1. Financial Statements, Note 12, "Derivative Instruments and Hedging Activities" and Note 9, "Debt" for further details.

Liquidity and Capital Resources

Our primary sources of liquidity include cash provided by operating activities and access to external capital. We believe that cash flows from operations and cash provided by short-term and long-term borrowings, when necessary, will be more than adequate to meet our ongoing operating requirements, scheduled principal and interest payments on debt, anticipated dividend payments and capital expenditures for the twelve months subsequent to the date of the issuance of this quarterly report, and our long-term liquidity requirements.

A significant portion of our trade receivables are concentrated in Europe. While these receivables are not concentrated in any specific customer and our allowance on these receivables factors in collectibility, we may encounter difficulties in our ability to collect due to the impact to our customers of any further economic downturn within Europe. We continue to have exposure to Agrokor, a company in Croatia, who entered into financial difficulty in 2017. The settlement plan related to this matter was announced in July 2018. We are currently evaluating the implications of the settlement plan, and do not expect it to have a significant impact on our financial statements upon finalization.

A significant portion of our cash flows from operating activities are generated outside the U.S. in currencies other than USD. As of June 30, 2018, approximately 40% of our cash and cash equivalents were located outside the U.S., largely denominated in foreign currencies. We accrue for tax consequences on the earnings of our foreign subsidiaries upon repatriation. When the earnings are considered indefinitely reinvested outside of the U.S., we do not accrue taxes. However, we will continue to assess the impact of the 2017 Tax Act on the tax consequences of future repatriations. We utilize a variety of tax planning and financing strategies in an effort to ensure that our worldwide cash is available in the locations in which it is needed. We periodically review and evaluate these strategies, including external committed and non-committed credit agreements accessible by MCBC and each of our operating subsidiaries. These financing arrangements, along with the cash generated from the operations of our U.S. segment, are sufficient to fund our current cash needs in the U.S.

Cash Flows and Use of Cash

Our business generates positive operating cash flow each year, and our debt maturities are of a longer-term nature. However, our liquidity could be impacted significantly by the risk factors we described in Part I—Item 1A. "Risk Factors" in our Annual Report.

Cash Flows from Operating Activities

Net cash provided by operating activities was approximately $1.3 billion for the six months ended June 30, 2018, compared to net cash provided by operating activities of $818.5 million for the six months ended June 30, 2017. This increase in net cash provided by operating activities of $479.3 million is primarily related to higher net income largely due to the proceeds received during the first quarter of $328.0 million related to the Adjustment Amount as defined and further discussed in Part I—Item 1. Financial Statements, Note 6, "Special Items", working capital improvements and lower pension contributions and interest.

Cash Flows from Investing Activities

Net cash used in investing activities of $397.2 million for the six months ended June 30, 2018, increased by $95.3 million compared to the six months ended June 30, 2017, driven primarily by lower proceeds related to asset disposals as well as increased outflows from other investing activities, including acquisitions.

Cash Flows from Financing Activities

Net cash used in financing activities was $524.7 million for the six months ended June 30, 2018, compared to net cash used in financing activities of $593.2 million for the six months ended June 30, 2017. This decrease was primarily driven by lower net repayments on debt and borrowings compared to prior year, partially offset by the repayment of borrowings under our commercial paper program during the first half of 2018 compared to an increase in borrowings under our commercial paper program during the first half of 2017.

57

Capital Resources

Cash and Cash Equivalents

As of June 30, 2018, we had total cash and cash equivalents of $792.9 million, compared to $418.6 million as of December 31, 2017, and $502.9 million as of June 30, 2017. The increase in cash and cash equivalents as of June 30, 2018, from both prior periods was primarily driven by the net proceeds from operating activities including the proceeds received during the first quarter of $328.0 million related to the Adjustment Amount as defined and further discussed in Part I—Item 1. Financial Statements, Note 6, "Special Items", partially offset by repayments of borrowings, capital expenditures and dividend payments.

Borrowings

During the three months ended June 30, 2018, there was no significant borrowing or repayment activity. The following table summarizes the maturities of our long-term debt, excluding short-term borrowings. Notional amounts are presented in USD based on the applicable exchange rate as of June 30, 2018. Refer to Part I—Item 1. Financial Statements, Note 9, "Debt" for details regarding the cross currency swaps on our $500 million2.25% senior notes due 2020 which economically converted these notes to EUR denominated.

Based on the credit profile of our lenders that are party to our credit facilities, we are confident in our ability to draw on our revolving credit facility if the need arises. As of June 30, 2018, we had approximately $1.5 billion available to draw under our $1.5 billion revolving multi-currency credit facility, as we did not have any borrowings drawn on this revolving credit facility or any commercial paper outstanding. Subsequent to quarter end, we extended the maturity date of our revolving credit facility by one year to July 7, 2023. In addition, we also currently utilize and will further utilize our cross-border, cross currency cash pool for liquidity needs. We also have JPY overdraft facilities, CAD and GBP lines of credit with several banks should we need additional short-term liquidity.

Under the terms of each of our debt facilities, we must comply with certain restrictions. These include restrictions on priority indebtedness (certain threshold percentages of secured consolidated net tangible assets), leverage thresholds, liens, and restrictions on certain types of sale lease-back transactions and transfers of assets. As of June 30, 2018, we were in compliance

58

with all of these restrictions and have met all debt payment obligations. All of our outstanding senior notes as of June 30, 2018, rank pari-passu.

Additionally, under the $1.5 billion revolving credit facility, the maximum leverage ratio is 5.25x debt to EBITDA, with a decline to 4.00x debt to EBITDA as of the last day of the fiscal quarter ending December 31, 2020.

See Part I—Item 1. Financial Statements, Note 9, "Debt" for a complete discussion and presentation of all borrowings and available sources of borrowing, including lines of credit.

Credit Rating

Our current long-term credit ratings are BBB-/Stable Outlook, Baa3/Stable Outlook and BBB(Low)/Stable Outlook with Standard and Poor's, Moody's Investor Services and DBRS, respectively. Our short-term credit ratings are A-3, Prime-3 and R-2(low), respectively. A securities rating is not a recommendation to buy, sell or hold securities, and it may be revised or withdrawn at any time by the applicable rating agency.

Foreign Exchange

Foreign exchange risk is inherent in our operations primarily due to the significant operating results that are denominated in currencies other than USD. Our approach is to reduce the volatility of cash flows and reported earnings which result from currency fluctuations rather than business related factors. Therefore, we closely monitor our operations in each country and seek to adopt appropriate strategies that are responsive to foreign currency fluctuations. Our financial risk management policy is intended to offset a portion of the potentially unfavorable impact of exchange rate changes on net income and earnings per share. See Part II—Item 8. Financial Statements and Supplementary Data, Note 17, "Derivative Instruments and Hedging Activities" of our Annual Report for additional information on our financial risk management strategies.

Our consolidated financial statements are presented in USD, which is our reporting currency. Assets and liabilities recorded in foreign currencies that are the functional currencies for the respective operations are translated at the prevailing exchange rate at the balance sheet date. Translation adjustments resulting from this process are reported as a separate component of other comprehensive income. Revenue and expenses are translated at the average exchange rates during the period. Gains and losses from foreign currency transactions are included in earnings for the period. The significant exchange rates to the USD used in the preparation of our consolidated financial results for the primary foreign currencies used in our foreign operations (functional currency) are as follows:

	Three Months Ended		Six Months Ended
	June 30, 2018	June 30, 2017	June 30, 2018	June 30, 2017
Weighted-Average Exchange Rate (1 USD equals)

The weighted-average exchange rates in the above table have been calculated based on the average of the foreign exchange rates during the relevant period and have been weighted according to the foreign denominated earnings before interest and taxes of the USD equivalent.

Capital Expenditures

We incurred $265.6 million, and have paid $351.1 million, for capital improvement projects worldwide in the six months ended June 30, 2018, excluding capital spending by equity method joint ventures, representing a decrease of $14.4 million from the $280.0 million of capital expenditures incurred in the six months ended June 30, 2017. This decrease is primarily due to the timing of projects as we currently expect to incur total capital expenditures of approximately $670 million for full year 2018, based on foreign exchange rates as of June 30, 2018. This expectation includes capital expenditures associated with the construction of our new British Columbia and Montreal breweries and excludes capital spending by equity method joint ventures.

We continue to focus on where and how we employ our planned capital expenditures, specifically strengthening our focus on required returns on invested capital as we determine how to best allocate cash within the business.

Contractual Obligations and Commercial Commitments

There were no material changes to our contractual obligations and commercial commitments since December 31, 2017, as reported in Part II - Item 7. Management's Discussion and Analysis, Contractual Obligations and Commercial Commitments in our Annual Report.

Guarantees

We guarantee indebtedness and other obligations to banks and other third parties for some of our equity method investments and consolidated subsidiaries. See Part I - Item 1. Financial Statements, Note 14, "Commitments and Contingencies" for further discussion.

Contingencies

We are party to various legal proceedings arising in the ordinary course of business, environmental issues and other contingencies. See Part I—Item 1. Financial Statements, Note 14, "Commitments and Contingencies" for further discussion.

Off-Balance Sheet Arrangements

In accordance with U.S. GAAP, our operating leases are not reflected in our unaudited condensed consolidated balance sheets. Refer to Part II—Item 8 Financial Statements, Note 19, "Commitments and Contingencies" in our Annual Report for further discussion of these off-balance sheet arrangements. As of June 30, 2018, we did not have any other material off-balance sheet arrangements (as defined in Item 303(a)(4)(ii) of Regulation S-K).

Outlook for 2018

In the U.S., we plan to continue to build distributor inventories in the second half of the year, as we prepare for further brewery system implementations. We also plan to continue to drive our portfolio strategy of building distinctive brands across all segments to meet the needs of American beer drinkers. We have an urgent focus on improving Coors Light trends through bolder execution of the "World's Most Refreshing Beer" and sharper feature and display activity while continuing the strong

60

share trends for Miller Lite through a bold competitive position. Additionally, we expect flavored malt beverage and cider performance to benefit from incremental volumes from Arnold Palmer Spiked distribution, flavor and pack innovations from Henry'sHard Sparkling, and the introduction of slim cans for Crispin Rosé. More broadly in above premium, we are working to accelerate our import share with both Sol and Peroni while strengthening the Blue Moon franchise and rapidly scaling our family of regional craft breweries.

In Canada, the commercial teams plan to continue to focus on strengthening the portfolio by stabilizing our premium brands performance, accelerating the growth of our above premium portfolio, and simplifying our offering in the value segment. In premium, Coors Light is our top priority and we expect to improve brand activations and promotional intensity with an emphasis on refreshment to drive feature and display. Our premiumization efforts are expected to drive an acceleration of the growth of our key import brand Heineken, as well as our Miller Genuine Draft and Coors Banquet brands. Trou du Diable, our most recent craft addition, is broadening our footprint in the world of craft in Quebec, and is delivering strong results. We have also lifted and shifted Leinenkugel’s Summer Shandy and Henry’s Hard Soda from the U.S. The recent addition of Coors Edge, a new non-alcoholic offering, is complementing Heineken 0.0 in this rapidly growing segment. In below premium, the recently launched Miller High Life brand continues to deliver strong results, while complementing our Pilsner and Black Label brands and underpinning continued segment share growth. Finally, as we look to ongoing productivity improvements, the construction of our new highly efficient brewery in British Columbia is on track for brewing in 2019 and planning for our new brewery in Quebec is advancing quickly.

In Europe, we are encouraged by the strong start to the summer selling season. Our teams plan to continue to use a balanced portfolio approach by building on momentum from the international growth of Staropramen outside of the Czech Republic, Coors Light and our craft and cider portfolio. Additionally, we expect to remain disciplined with retail execution and optimization of our brewery network and infrastructure.

In International, strong year-to-date performance gives us added confidence for the remainder of 2018. We expect the second half of the year to build on success in Latin America, including Mexico, Paraguay, and Honduras, along with further development of our Asia Pacific markets, such as South Korea. We plan to continue to focus our efforts on succeeding in high-potential markets and brands that we expect to play a pivotal role in reaching our long-term top- and bottom-line international growth targets. We expect our International segment to be a meaningful driver of results this year.

Pension Plans

We currently anticipate approximately $10 million of cash contributions to our defined benefit pension plans in 2018, based on foreign exchange rates as of June 30, 2018. BRI and BDL contributions to their respective defined benefit pension plans are excluded here, as they are not consolidated in our financial statements.

Interest

We anticipate 2018 Corporate net interest expense of approximately $330 million, based on foreign exchange and interest rates as of June 30, 2018.

Tax

We expect to realize net benefits from the 2017 Tax Act, primarily driven by the lower federal corporate income tax rate of 21% and accelerated depreciation of qualified assets for tax purposes. As an additional result of the 2017 Tax Act, we expect a long-term consolidated effective tax rate in the range of 20% to 24%. However, we will continue to evaluate the impacts of the 2017 Tax Act as we further understand its implications, as well as the related, and yet to be issued, regulations and interpretations which could impact this outlook.

Dividends and Stock Repurchases

As a result of the Acquisition, we currently plan to maintain our current quarterly dividend of $0.41 per share until we achieve a leverage ratio of 3.75x debt to EBITDA on a rating agency basis, which we expect to achieve near the second half of 2019. Once this target is achieved, we currently intend to reinstitute a dividend payout-ratio target based upon the annual trailing EBITDA and raise our quarterly dividend accordingly. We have suspended our share repurchase program as we continue to pay down debt which we plan to revisit as we deleverage.

Critical Accounting Estimates

Our accounting policies and accounting estimates critical to our financial condition and results of operations are set forth in our Annual Report and did not change during the first half of 2018. See Part I—Item 1. Financial Statements, Note 2, "New

61

Accounting Pronouncements" for discussion of recently adopted accounting pronouncements. See also Part I—Item 1. Financial Statements, Note 8, "Goodwill and Intangible Assets" for discussion of the results of the 2017 annual impairment testing analysis and the related risks to our indefinite-lived intangible brand assets and goodwill amounts associated with our reporting units.

New Accounting Pronouncements Not Yet Adopted

Leases

In February 2016, the FASB issued authoritative guidance intended to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing key information about leasing arrangements. Under the new guidance, lessees will be required to recognize a right-of-use asset and a lease liability, measured on a discounted basis, at the commencement date for all leases with terms greater than twelve months. Additionally, this guidance will require disclosures to help investors and other financial statement users to better understand the amount, timing, and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements. This guidance is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted. The guidance should be applied under a modified retrospective transition approach, with an option to apply the guidance either at the beginning of the earliest comparative period presented in the adoption-period financial statements, or to apply the new guidance at the adoption date. We currently anticipate that we will apply the guidance at the beginning of the period of adoption; however, this expectation may change following the completion of our evaluation of the impact of this guidance on our financial statements. We are currently evaluating the potential impact on our financial position and results of operations upon adoption of this guidance. This guidance will result in our existing operating leases, for certain real estate and equipment, to be recognized on our balance sheet. We will further analyze our lease arrangements as we complete our assessment and implementation of this new guidance.

See Part I—Item 1. Financial Statements, Note 2, "New Accounting Pronouncements" for a description of all new accounting pronouncements.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the normal course of business, we actively manage our exposure to various market risks by entering into various supplier-based and market-based hedging transactions, authorized under established risk management policies that place clear controls on these activities. Our objective in managing these exposures is to decrease the volatility of our earnings and cash flows due to changes in underlying rates and costs. The counterparties to our market-based transactions are generally highly rated institutions. We perform assessments of their credit risk regularly. Our market-based transactions include a variety of derivative financial instruments, none of which are used for trading or speculative purposes.

For details of our derivative instruments that are presented on the balance sheet, including their fair values as of period end, see Part I—Item 1. Financial Statements, Note 12, "Derivative Instruments and Hedging Activities". On a rolling twelve-month basis, maturities of derivative financial instruments held on June 30, 2018, based on foreign exchange rates as of June 30, 2018, are as follows:

Total		Less than 1 year		1 - 3 years		3 - 5 years			More than 5 years
(In millions)
$	114.4	$	53.6	$	60.9	$	(0.1	)	$	—

Sensitivity Analysis

Our market risk sensitive derivative and other financial instruments, as defined by the SEC, are foreign currency forward contracts, debt, commodity swaps and commodity options. We monitor foreign exchange risk, interest rate risk, commodity risk and related derivatives using a sensitivity analysis.

62

The following table presents the results of the sensitivity analysis, which reflects the impact of a hypothetical 10% adverse change in each of these risks to our derivative and debt portfolio:

	As of
	June 30, 2018			December 31, 2017
	(In millions)
Estimated fair value volatility
Foreign currency risk:
Forwards	$	(36.5	)	$	(36.5	)
Foreign currency denominated debt	$	(287.8	)	$	(310.0	)
Swaps	$	(51.9	)	$	—
Interest rate risk:

Commodity price risk:
Commodity swaps	$	(81.8	)	$	(43.5	)
Commodity options	$	—		$	—

The volatility of the applicable rates and prices are dependent on many factors that cannot be forecast with reliable accuracy. Therefore, actual changes in fair values could differ significantly from the results presented in the table above.

ITEM 4.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of our disclosure controls and procedures as such item is defined under Rule 13a-15(e) under the Exchange Act. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2018, to provide reasonable assurance that information required to be disclosed in our reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Management necessarily applies its judgment in assessing the costs and benefits of such controls and procedures that, by their nature, can only provide reasonable assurance regarding management's control objectives. Also, we have investments in certain unconsolidated entities that we do not control or manage.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)) during the three months ended June 30, 2018, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1.    LEGAL PROCEEDINGS

For information regarding litigation, other disputes and environmental and regulatory proceedings see Part I—Item 1. Financial Statements, Note 14, "Commitments and Contingencies" for additional information.

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, none of these disputes and 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.

ITEM 1A.    RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I—Item 1A. "Risk Factors" in our Annual Report, which could materially affect our business, financial condition and/or future results. There have been no material changes to the risk factors contained in our Annual Report except as noted below. The

63

risks described in our Annual Report are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially adversely affect our business, financial condition, cash flows and/or future results.

Our Canadian business faces numerous risks relating to its proposed joint venture in the Canadian cannabis industry.

On August 1, 2018, a wholly-owned subsidiary within our Canadian business entered into a definitive agreement to form a joint venture with The Hydropothecary Corporation (a/k/a HEXO), a Canadian entity listed on the Toronto Stock Exchange that serves the Canadian cannabis market. The joint venture will pursue opportunities to develop non-alcoholic, cannabis-infused beverages for the Canadian market following legalization. The formation of the joint venture and related actions and investments have not yet occurred and are subject to future closing conditions, which may not be met. In addition, the success and consumer acceptance of any products produced by the joint venture cannot be assured. Further, our Canadian subsidiary’s involvement in the Canadian cannabis industry may negatively impact consumer perception of our current brands or business partner, investor or public sentiment regarding our Canadian beer business or our company. The emerging cannabis industry in Canada and in other jurisdictions is evolving rapidly and subjects us to a high degree of political, legal and regulatory uncertainty, including when and if regulations in Canada will ultimately be adopted that would allow the sale of the non-alcoholic beverages contemplated by the joint venture. The occurrence of any of the above risks could have a material adverse effect on our business.

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 United States; Molson Coors Canada ("MCC" or Canada segment), operating in Canada; Molson Coors Europe (Europe segment), operating in Bulgaria, Croatia, Czech Republic, Hungary, Montenegro, Republic of Ireland, Romania, Serbia, the United Kingdom 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, 2017 ("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". We adopted the FASB's new revenue recognition standard and the presentation of net periodic pension and other postretirement benefit cost standard during the first quarter of 2018. We also adopted the updated hedge accounting standard during the second quarter of 2018. The adoption of each of these accounting standards was effective January 1, 2018.

Our historical unaudited condensed consolidated financial statements have been revised to reflect the retrospective application of our change in accounting policy for calculating the market-related value of pension plan assets used to determine net periodic pension cost as discussed in our Annual Report.

The results of operations for the three and six months ended June 30, 2018, are not necessarily indicative of the results that may be achieved for the full year.

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" and Note 5, "Share-Based Payments" for further discussion. We also had non-cash activities related to capital expenditures incurred but not yet paid, and the recognition of capital leases. These non-cash activities are excluded from our unaudited condensed consolidated statements of cash flows and were $153.0 million and $163.1 million for the six months ended June 30, 2018, and June 30, 2017, respectively.

Discontinued Operations

We no longer present the activity related to foreign exchange movements nor the liabilities associated with our indemnities resulting from the historical sale of the Kaiser business (as discussed in Note 19 of the Notes included in our Annual Report) within discontinued operations and have accordingly reclassified the activity into other income within continuing operations of the unaudited condensed consolidated statements of operations, and the liabilities into other current and long-term liabilities within the unaudited condensed consolidated balance sheets. This change has been applied retrospectively and prospectively. As a result, we reclassified a foreign exchange gain from discontinued operations to other income (expense), net of $1.6 million and $1.0 million for the three and six months ended June 30, 2017.

Revenue Recognition

We account for revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers, which we adopted on January 1, 2018, using the modified retrospective transition approach (see Note 2, "New Accounting Pronouncements" for impacts of adoption).

Our net sales represent the sale of beer and other malt beverages (including adjacencies, such as cider and hard soda), net of excise tax. Sales are stated net of incentives, discounts and returns. Sales of products are for cash or otherwise agreed upon credit terms. Our payment terms vary by location and customer, however, the time period between when revenue is recognized and when payment is due is not significant. Our revenue generating activities have a single performance obligation and are recognized at the point in time when control transfers and our obligation has been fulfilled, which is when the related goods are shipped or delivered to the customer, depending upon the method of distribution and shipping terms. Where our products are sold under consignment arrangements, revenue is not recognized until control has transferred, which is when the product is sold to the end customer. Revenue is measured as the amount of consideration we expect to receive in exchange for the sale of our product. The cost of various programs, such as price promotions, rebates and coupons are treated as a reduction of sales. In certain of our markets, we make cash payments to customers such as slotting or listing fees, or payments for other marketing or promotional activities. These cash payments are recorded as a reduction of revenue unless we receive a distinct good or service as defined under ASC 606. Specifically, a good or service is considered distinct when it is separately identifiable from other promises in the contract, we receive a benefit from the good or service, and the benefit is separable from the sale of our product to the customer.

Certain payments made to customers are conditional on the achievement of volume targets, marketing commitments, or both. If paid in advance, we record such payments as prepayments and amortize them over the relevant period to which the customer commitment is made (generally up to five years). When the payment is not for a distinct good or service, or fair value cannot be reasonably estimated, the amortization of the prepayment or the cost as incurred is recorded as a reduction of revenue. Where a distinct good or service is received and fair value can be reasonably estimated, the cost is included as marketing, general and administrative expenses. The amounts deferred are reassessed regularly for recoverability over the contract period and are impaired where there is objective evidence that the benefits will not be realized or the asset is otherwise not recoverable. Separately, as discussed below, we analyze whether these advance payments contain a significant financing component for potential adjustment to the transaction price.

Our primary revenue generating activity represents the sale of beer and other malt beverages to customers, including both domestic and exported product sales. Our customer could be a distributor, retail or on-premise outlet, depending on the market. The majority of our revenues are generated from brands that we own and brew ourselves, however, we also import or brew and sell certain non-owned partner brands under licensing and related arrangements. In addition, primarily in the U.K., as well as certain other countries in our Europe segment, we sell other beverage companies' products to on-premise customers to provide them with a full range of products for their retail outlets. We refer to this as the "factored brand business." Sales from this business are included in our net sales and cost of goods sold when ultimately sold. In the factored brand business, we normally purchase inventory, which includes excise taxes charged by the vendor, take orders from customers for such brands, negotiate with the customers on pricing and invoice customers for the product and related costs of delivery. In addition, we incur the risk of loss at times we are in possession of the inventory and for the receivables due from the customers. Revenues for owned brands, partner and imported brands, as well as factored brands are recognized at the point in time when control is transferred to the customer as discussed above.

Other Revenue Generating Activities

We contract manufacture for other brewers in some of our markets. These contractual agreements require us to brew, package and ship certain brands to these brewers, who then sell the products to their own customers in their respective markets. Revenues under contract brewing arrangements are recognized when our obligation related to the finished product is fulfilled and control of the product transfers to these other brewers.

We also have licensing agreements with third party partners who brew and distribute our products in various markets across our segments. Under these agreements, we are compensated based on the amount of products sold by our partners in these markets at an agreed upon royalty rate or profit percentage. We apply the sales-based royalty practical expedient to these licensing arrangements and recognize revenue as product is sold by our partners at the agreed upon rate.

We have evaluated these other revenue generating activities under the disaggregation disclosure criteria outlined within the guidance and concluded that these other revenue generating activities are immaterial for separate disclosure. See Note 3, "Segment Reporting", for disclosure of revenues by geographic segment.

Variable Consideration

Our revenue generating activities include variable consideration which is recorded as a reduction of the transaction price based upon expected amounts at the time revenue for the corresponding product sale is recognized. For example, customer promotional discount programs are entered into with certain distributors for certain periods of time. The amount ultimately reimbursed to distributors is determined based upon agreed-upon promotional discounts which are applied to distributors' sales to retailers. Other common forms of variable consideration include volume rebates for meeting established sales targets, and coupons and mail-in rebates offered to the end consumer. The determination of the reduction of the transaction price for variable consideration requires that we make certain estimates and assumptions that affect the timing and amounts of revenue and liabilities recorded. We estimate this variable consideration, including analyzing for a potential constraint on variable consideration, by taking into account factors such as the nature of the promotional activity, historical information and current trends, availability of actual results, and expectations of customer and consumer behavior.

We do not have standard terms that permit return of product; however, in certain markets where returns occur we estimate the amount of returns as variable consideration based on historical return experience and adjust our revenue accordingly. Products that do not meet our high quality standards are returned by the customer or recalled and destroyed and are recorded as a reduction of revenue. The reversal of revenue is recorded upon determination that the product will be recalled and destroyed. We estimate the costs required to facilitate product returns and record them in cost of goods sold as required.

During the three and six months ended June 30, 2018, adjustments to revenue from performance obligations satisfied in the prior period due to changes in estimates in variable consideration were immaterial.

Significant Financing Component and Costs to Obtain Contracts

In certain of our businesses where such practices are legally permitted, we make loans or advanced payments to retail outlets that sell our brands. For arrangements that do not span greater than one year, we apply the practical expedient available under ASC 606 and do not adjust the transaction price for the effects of a potential significant financing component. We further analyze arrangements that span greater than one year on an ongoing basis to determine whether a significant financing component exists. No such arrangements existed during the six months ended June 30, 2018.

Advance payments to customers, where legally permitted, are deferred and amortized as a reduction to revenue over the expected period of benefit and tested for recoverability as appropriate. All other costs to obtain contracts and fulfill are expensed as incurred based on the nature, significance and expected benefit of these costs relative to the contract.

Contract Assets and Liabilities

We continually evaluate whether our revenue generating activities and advanced payment arrangements with customers result in the recognition of contract assets or liabilities. No such assets or liabilities existed as of June 30, 2018, or December 31, 2017. Separately, trade accounts receivable, including affiliate receivables, approximates receivables from contracts with customers.

Shipping and Handling

Freight costs billed to customers for shipping and handling are recorded as revenue. Shipping and handling expense related to costs incurred to deliver product are recognized within cost of goods sold. We account for shipping and handling activities that occur after control has transferred as a fulfillment cost as opposed to a separate performance obligation, and the costs of shipping and handling are recognized concurrently with the related revenue.

Excise Tax

Excise tax remitted to tax authorities are government-imposed excise taxes on beer. Excise taxes are shown in a separate line item in the unaudited condensed consolidated statements of operations as a reduction of sales. Excise taxes are recognized as a current liability within accounts payable and other current liabilities on the unaudited condensed consolidated balance sheets, with the liability subsequently reduced when the taxes are remitted to the tax authority.

Net Periodic Pension Cost Revised Accounting Policy

The following table presents the impacts to our quarterly information resulting from the retrospective application of our change in accounting policy for calculating the market-related value of pension plan assets used to determine net periodic pension cost effective in the fourth quarter of 2017 as discussed in Note 1 of the Notes of our Annual Report. The below "As Adjusted" amounts have been further adjusted to reflect the adoption of the accounting standard on the presentation of net periodic pension and postretirement benefit cost. See Note 2, "New Accounting Pronouncements".

New Accounting Pronouncements

New Accounting Pronouncements Recently Adopted

Pension and Other Postretirement Benefit Plans

In March 2017, the FASB issued authoritative guidance intended to improve the consistency, transparency and usefulness of financial information related to defined benefit pension or other postretirement plans. Under the new guidance, an employer must disaggregate the service cost component from the other components of net benefit cost within the statements of operations. Specifically, the new guidance requires us to report only the service cost component in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period; while the other components of net benefit cost are now presented in the unaudited condensed consolidated statements of operations separately from the service cost component and outside of operating income. The amendments in this update also allow only the service cost component to be eligible for capitalization when applicable. We have also determined that only service cost will be reported within each operating segment and all other components will be reported within the Corporate segment. The guidance related to the income statement presentation of service costs and other pension and postretirement benefit costs is applied retrospectively, while the capitalization of service costs component is applied prospectively. We adopted this guidance as of January 1, 2018, which was a classification adjustment only and had no impact to our consolidated net income. The adoption of this guidance resulted in the following retrospective adjustments within our unaudited condensed consolidated results of operations:

(1) As discussed in detail within Note 1, "Basis of Presentation and Summary of Significant Accounting Policies", our historical unaudited condensed consolidated financial statements have been revised to reflect the retrospective application of our change in accounting policy for calculating the market-related value of pension plan assets used to determine net periodic pension cost. The change was effective in the fourth quarter of 2017.

The following table shows the (increase) decrease for the respective line item within the unaudited condensed consolidated statement of operations for segment reporting for the three months ended June 30, 2017:

Revenue Recognition

In May 2014, the FASB issued authoritative guidance related to new accounting requirements for the recognition of revenue from contracts with customers. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for the goods or services.

We adopted this guidance and related amendments as of January 1, 2018, applying the modified retrospective transition approach to all contracts. Based on our comprehensive assessment of the new guidance, including our evaluation of the five-step approach outlined within the guidance, we concluded that the adoption did not have a significant impact to our core revenue generating activities. However, the adoption resulted in a change in presentation of certain cash payments made to customers as well as the timing of recognition of certain promotional discounts. Specifically, certain cash payments to customers were previously recorded within marketing, general and administrative expenses in the unaudited condensed consolidated statements of operations. Upon the adoption of the new guidance, many of these cash payments did not meet the specific criteria within the new guidance of providing a “distinct” good or service, and therefore, were required to be presented as a reduction of revenue. Based on foreign exchange rates as of June 30, 2018, we currently anticipate that the impact of this change will result in a reduction of both revenue and marketing, general and administrative expenses by approximately $60 million to $70 million during 2018, primarily within our Canada segment, with no impact to full year net income. However, actual results may differ from these estimates. Furthermore, upon adoption of the new guidance, certain of our promotional discounts which are deemed variable consideration under the new guidance, are now recognized at the time of the related shipment of product, which is earlier than recognized under historical guidance. We anticipate that this change in recognition timing will shift financial statement recognition primarily amongst quarters, however, do not anticipate that the full-year impact will be significant to our financial results. We also evaluated the requirements of the new guidance on our other revenue generating activities such as contract brewing and license arrangements, and concluded that no changes to our historical accounting treatment was required.

As a result of the cumulative impact of adopting the new guidance, we recorded a reduction to opening retained earnings of $27.8 million as of January 1, 2018, with an offsetting increase primarily within accounts payable and other current liabilities and the related tax effects, related primarily to the accelerated recognition of certain promotional discounts. Results for reporting periods beginning after January 1, 2018, are presented under the new guidance, while prior period amounts have not been adjusted and continue to be reported in accordance with historical accounting guidance. The following tables provide a comparison of our current period results of operations and financial position under the new guidance, versus our financial statements if the historical guidance had continued to be applied:

These changes are primarily driven by the reclassification of certain cash payments to customers from marketing, general and administrative expenses to a reduction of revenue, as well as the change in the timing of recognition of certain promotional discounts and cash payments to customers. This adoption 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 further details on our significant accounting policies for revenue recognition pursuant to the new guidance.

Financial and Commodity Risks

In August 2017, the FASB issued authoritative guidance intended to refine and expand hedge accounting for both financial and commodity risks. The revised guidance will create more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes. In addition, this guidance makes certain targeted improvements to simplify the application of hedge accounting guidance. This guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted. We have elected to early adopt this guidance during the second quarter of 2018. All transition requirements have been applied to hedging relationships existing on the date of adoption and the effect of the adoption is reflected as of January 1, 2018. The adoption of this guidance did not result in a cumulative adjustment to the opening balance of retained earnings as of January 1, 2018, and did not have any other material effect on our results of operations, financial position or cash flows. All required disclosures under the new guidance have been made in Note 12, "Derivative Instruments and Hedging Activities".

New Accounting Pronouncements Not Yet Adopted

In February 2018, the FASB issued authoritative guidance intended to improve the usefulness of financial information related to the enactment of the 2017 U.S. Tax Cuts and Jobs Act (the "2017 Tax Act"). This guidance provides an option to reclassify from accumulated other comprehensive income 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. This guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted. We are currently evaluating the potential impact on our financial statements in order to determine whether to elect to make this reclassification upon adoption of this guidance.

In February 2016, the FASB issued authoritative guidance intended to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing key information about leasing arrangements. Under the new guidance, lessees will be required to recognize a right-of-use asset and a lease liability, measured on a discounted basis, at the commencement date for all leases with terms greater than twelve months. Additionally, this guidance will require disclosures to help investors and other financial statement users to better understand the amount, timing, and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements. This guidance is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted. The guidance should be applied under a modified retrospective transition approach, with an option to apply the guidance either at the beginning of the earliest comparative period presented in the adoption-period financial statements, or to apply the new guidance at the adoption date. We currently anticipate that we will apply the guidance at the beginning of the period of adoption; however, this expectation may change following the completion of our evaluation of the impact of this guidance on our financial statements. We are currently evaluating the potential impact on our financial position and results of operations upon adoption of this guidance. This guidance will result in our existing operating leases, for certain real estate and equipment, to be recognized on our balance sheet. We will further analyze our lease arrangements as we complete our assessment and implementation of this new guidance.

Other than the items noted above, there have been no new accounting pronouncements not yet effective or adopted in the current year that we believe have a significant impact, or potential significant impact, to our unaudited condensed consolidated interim financial statements.

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 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 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 are now reported within each operating segment, as discussed in Note 2, "New Accounting Pronouncements", and all other components are reported, retrospectively and prospectively, within the Corporate segment in accordance with how our chief operating decision maker evaluates the performance of our business.

No single customer accounted for more than 10% of our consolidated sales for the three and six months ended June 30, 2018, or June 30, 2017. 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 in consolidation and are primarily related to U.S. segment sales to the other segments.

The following tables present net sales, income (loss) before income taxes and total assets by segment:

(1) Segment results for the three and six months ended June 30, 2017, have been adjusted to reflect the adoption of the new accounting pronouncement for pension and other postretirement benefit costs as well as the reclassification of all non-service cost components of pension and other postretirement costs to Corporate. See Note 2, "New Accounting Pronouncements" for further details.

(2) During the first quarter of 2017, we received payment and recorded a gain of CAD 10.6 million, or $8.1 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.

(3) During the three months ended March 31, 2017, we recorded a provision for an estimate of uncollectible receivables of approximately$11 millionrelated to Agrokor, a large customer in Croatia. We have subsequently reduced this exposure and as of June 30, 2018, our estimated provision of uncollectible receivables from Agrokor totals approximately $4 million. The settlement plan related to this matter was announced in July 2018. We are currently evaluating the implications of the settlement plan, and do not expect it to have a significant impact on our financial statements upon finalization.Separately, during the first quarter of 2017, we released an indirect tax loss contingency, which was initially recorded in the fourth quarter of 2016, for a benefit of approximately$50 million. See Note 14, "Commitments and Contingencies" for details.

(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 6, "Special Items". Additionally, related to the unrealized mark-to-market valuation on our commodity hedge positions, we recorded an unrealized gain of $45.1 million and an unrealized loss of $39.6 million during the three and six months ended June 30, 2018, respectively, compared to an unrealized loss of $23.4 million and an unrealized gain of $39.7 million during the three and six months ended June 30, 2017, respectively.

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, consolidate these entities. None of our consolidated VIEs held debt as of June 30, 2018, or December 31, 2017. 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. As of June 30, 2018, and December 31, 2017, our consolidated VIEs were Cobra Beer Partnership, Ltd. ("Cobra U.K."), Grolsch U.K. Ltd. ("Grolsch"), Rocky Mountain Metal Container ("RMMC") and Rocky Mountain Bottle Company ("RMBC"). 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 $55.4 million and $38.1 million recorded as of June 30, 2018, and December 31, 2017, 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.

The following summarizes the assets and liabilities of our consolidated VIEs (including noncontrolling interests):

Share-Based Payments

We have one share-based compensation plan, the MCBC Incentive Compensation Plan (the "Incentive Compensation Plan"), as of June 30, 2018, and all outstanding awards fall under this plan. During the three and six months endedJune 30, 2018, and June 30, 2017, we recognized share-based compensation expense related to the following Class B common stock awards to certain directors, officers and other eligible employees, pursuant to the Incentive Compensation Plan: RSUs, DSUs, PSUs and stock options.

As of June 30, 2018, there was $73.3 million of total unrecognized compensation expense from all share-based compensation arrangements granted under the Incentive Compensation Plan, related to unvested awards. This total compensation expense is expected to be recognized over a weighted-average period of 2.1 years.

The total intrinsic values of stock options and SOSARs exercised during the six months endedJune 30, 2018, and June 30, 2017, were $5.1 million and $5.3 million, respectively. During the six months endedJune 30, 2018, and June 30, 2017, cash received from stock option exercises was $6.3 million and $1.1 million, respectively, and total tax benefits realized, including excess tax benefits, from share-based awards vested or exercised was $5.9 million and $19.2 million, respectively.

The fair value of each option granted in the first half of 2018 and 2017 was determined on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:

	Six Months Ended
	June 30, 2018	June 30, 2017
Risk-free interest rate	2.65%	2.04%
Dividend yield	2.08%	1.64%
Volatility range	22.36%-24.14%	22.40%-22.88%
Weighted-average volatility	22.81%	22.52%
Expected term (years)	5.3	5.1
Weighted-average fair market value	$15.44	$18.66

The risk-free interest rates utilized for periods throughout the contractual life of the stock options are based on a zero-coupon U.S. Treasury security yield at the time of grant. Expected volatility is based on a combination of historical and implied volatility of our stock. The expected term of stock options is estimated based upon observations of historical employee option exercise patterns and trends of those employees granted options in the respective year.

The fair value of the market metric for each PSU granted in the first half of 2018 and 2017 was determined on the date of grant using a Monte Carlo model to simulate total stockholder return for MCBC and peer companies with the following weighted-average assumptions:

	Six Months Ended
	June 30, 2018	June 30, 2017
Risk-free interest rate	2.34%	1.59%
Dividend yield	2.08%	1.64%
Volatility range	13.03%-81.87%	13.71%-80.59%
Weighted-average volatility	22.76%	24.24%
Expected term (years)	2.8	2.8
Weighted-average fair market value	$78.30	$97.13

The risk-free interest rates utilized for periods throughout the expected term of the PSUs are based on a zero-coupon U.S. Treasury security yield at the time of grant. Expected volatility is based on historical volatility of our stock as well as the stock of our peer firms, as shown within the volatility range above, for a period from the grant date consistent with the expected term. The expected term of PSUs is calculated based on the grant date to the end of the performance period.

As of June 30, 2018, there were 3.4 million shares of the Company's Class B common stock available for issuance as awards under the Incentive Compensation Plan.

(1) Charges for the three and six months ended June 30, 2018, relate to the planned closure of the Colfax, California cidery, and consist primarily of accelerated depreciation in excess of normal depreciation. Charges for the three and six months ended June 30, 2017, relate to the closure of the Eden, North Carolina, brewery.

(2) For the three and six months ended June 30, 2018, we incurred charges consisting primarily of accelerated depreciation in excess of normal depreciation related to the planned closures of the Vancouver and Montreal breweries, which are currently expected to occur in 2019 and 2021, respectively. Charges for the three and six months ended June 30, 2017, relate primarily to accelerated depreciation in excess of normal depreciation related to the above mentioned planned closure of the Vancouver brewery.

(3) For the three and six months ended June 30, 2018, we incurred charges primarily related to the closure of the Burton South brewery, which closed during the first quarter of 2018. For the three and six months ended June 30, 2017, we incurred charges consisting primarily of accelerated depreciation in excess of normal depreciation related to the Burton South brewery closure.

(4) For the three and six months ended June 30, 2018, we incurred charges related to the exit of our China business.

(5) On October 11, 2016, we completed the Acquisition for $12.0 billion in cash, subject to a downward adjustment as described in the purchase agreement. This purchase price "Adjustment Amount," as defined in the purchase agreement, required payment to MCBC if the unaudited EBITDA for the Miller International Business for the twelve months prior to closing was below $70 million.

Throughout the process outlined in the purchase agreement, significant uncertainty remained on the ultimate outcome of the Adjustment Amount. As a result, no adjustment to purchase accounting was made through the completion of the measurement period in October 2017. Subsequently, on January 21, 2018, MCBC and ABI entered into a settlement agreement related to the purchase price adjustment under the purchase agreement, and on January 26, 2018, pursuant to the settlement agreement, ABI paid to MCBC $330.0 million, of which $328.0 million constitutes the Adjustment Amount. 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 within our unaudited condensed consolidated statement of cash flows for the six months ended June 30, 2018. MCBC and ABI also agreed to certain mutual releases as further described in the settlement agreement which was filed as an exhibit to a Current Report on Form 8-K filed January 22, 2018.

Restructuring Activities

Beginning in 2016, restructuring initiatives related to the integration of MillerCoors after the completion of the Acquisition were implemented in order to operate a more efficient business and achieve cost saving targets which to-date resulted in reduced employment levels by approximately 106 employees. Total restructuring costs related to integration initiatives represent the majority of the charges within the table below by segment. Severance costs related to these restructuring activities were recorded as special items within our unaudited condensed consolidated statements of operations. 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 in the future, however, we are unable to estimate the amount of charges at this time.

We have continued our ongoing assessment of our supply chain strategies across our segments in order to align with our cost saving objectives. As part of this strategic review, which began in 2014, we have had restructuring activities related to the closure or planned closure of breweries, as well as activities related to business efficiencies. As a result, we have reduced employment levels by a total of 450 employees. Consequently, we recognized severance and other employee-related charges, which we have recorded as special items within our unaudited condensed consolidated statements of operations. We will continue to evaluate our supply chain network and seek opportunities for further efficiencies and cost savings, and we therefore 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.

The accrued restructuring balances 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.

Income Tax

	Three Months Ended				Six Months Ended
	June 30, 2018		June 30, 2017		June 30, 2018		June 30, 2017
Effective tax rate	18	%	27	%	19	%	26	%

The decrease in the effective tax rate during the second quarter and first half of 2018 versus 2017, is primarily driven by the reduction of the statutory U.S. federal corporate income tax rate from 35% to 21% as a result of the 2017 Tax Act. Our effective tax rates were also affected by the impact of discrete items. Specifically, we recognized a net discrete tax benefit of $1.2 million during the second quarter of 2018, and net discrete tax expense of $4.3 million during the first half of 2018. During the second quarter and first half of 2017, we recognized a net discrete tax benefit of $1.3 million and $9.7 million, respectively.

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.

Additionally, we continue to evaluate the impacts of the 2017 Tax Act. As we further understand its implications, as well as the related, and yet to be issued, regulations and interpretations, our effective tax rate could be impacted. For example, subsequent to the enactment, the FASB staff concluded that companies should make an accounting policy election to account for the tax effects of the global intangible low-taxed income (“GILTI”) either as a component of income tax expense in the future period the tax arises, or as a component of deferred taxes on the related investments in foreign subsidiaries. We are currently evaluating the GILTI provisions of the 2017 Tax Act and the related implications and have not finalized our accounting policy election, however, have preliminarily concluded that we will record as a periodic expense as incurred, and therefore, have not recorded deferred taxes for GILTI. We will continue to evaluate in future periods and will finalize our accounting policy election at that time.

We did not make any material adjustments to the amounts recorded as of December 31, 2017, as a result of the 2017 Tax Act, however, we continue to consider these amounts provisional for the reasons discussed above. Additional impacts from the 2017 Tax Act will be recorded as they are identified during the measurement period pursuant to SEC Staff Accounting Bulletin No. 118 ("SAB 118"). Our determination of the tax effects of the 2017 Tax Act will be completed no later than one year from the enactment date as permitted under SAB 118. Any adjustments to provisional amounts that are identified during the measurement period will be recorded and disclosed in the reporting period in which the adjustment is determined. The complexity of the 2017 Tax Act could necessitate the need to use the full one year measurement period to adequately interpret, analyze and conclude upon the tax effects of the 2017 Tax Act as of the enactment date.

(1) During the first quarter of 2018, we completed the acquisition of Aspall Cyder Limited, an established premium cider business in the U.K. As part of the preliminary purchase price accounting in the first quarter of 2018, goodwill generated in conjunction with this acquisition has been recorded within our Europe segment, subject to normal purchase accounting adjustments.

(2) During the second quarter of 2018, we recorded adjustments to the preliminary purchase price allocation related to our acquisition of Le Trou du Diable, which was completed in the fourth quarter of 2017.

The changes in the gross carrying amounts of intangibles from December 31, 2017, to June 30, 2018, are primarily driven by the impact of foreign exchange rates, as a significant amount of intangibles are denominated in foreign currencies.

Based on foreign exchange rates as of June 30, 2018, the estimated future amortization expense of intangible assets is as follows:

Fiscal year	Amount
	(In millions)
2018 - remaining	$	111.5
2019	$	222.8
2020	$	221.8
2021	$	215.5
2022	$	210.9

Amortization expense of intangible assets was $56.2 million and $55.1 million for the three months endedJune 30, 2018, and June 30, 2017, respectively, and $112.8 million and $110.3 million for the six months ended June 30, 2018, and June 30, 2017, respectively. This expense is primarily presented within marketing, general and administrative expenses on the unaudited condensed consolidated statements of operations.

Annual Goodwill Impairment Testing

We completed our required annual goodwill and indefinite-lived intangible impairment testing as of October 1, 2017, 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.

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 in Part II—Item 8 Financial Statements, Note 11, "Goodwill and Intangible Assets" in our Annual Report.

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 assessment and incorporate into the analyses as appropriate. These facts and circumstances are subject to change and may impact future analyses. For example, subsequent to the completion of our annual impairment testing, we considered the implications of the enactment of the 2017 Tax Act on our U.S. reporting unit and indefinite-lived brand valuations. The results of our preliminary analysis indicated that the implications are expected to be favorable, keeping all other assumptions constant.

While historical performance and current expectations have resulted in fair values of our reporting units and indefinite-lived intangible assets in excess of carrying values, if our assumptions are not realized, it is possible that an impairment charge may need to be recorded in the future.

Indefinite and Definite-Lived Intangibles

Regarding indefinite and definite-lived intangibles, we continuously monitor the performance of the underlying assets for potential triggering events suggesting an impairment review should be performed. No such triggering events were identified in the first half of 2018 that resulted in an impairment.

(1) The fair value hedges related to these notes have been settled and are being amortized over the life of the respective note.

(2) During the second quarter, we entered into 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 economically converted our $500 million2.25% senior notes due 2020 and associated interest to EUR denominated, which will result in a EUR interest rate to be received at 0.85%. See Note 12, "Derivative Instruments and Hedging Activities" for further details.

(3) As of June 30, 2018, we had $6.9 million in bank overdrafts and $71.6 million in bank cash related to our cross-border, cross-currency cash pool, for a net positive position of $64.7 million. As of December 31, 2017, we had $1.2 million in bank overdrafts and $37.8 million in bank cash related to our cross-border, cross-currency cash pool for a net positive position of $36.6 million. We had total outstanding borrowings of $5.4 million and $3.2 million under our two JPY overdraft facilities as of June 30, 2018, and December 31, 2017, respectively. In addition, we have GBP and CAD lines of credit under which we had no borrowings as of June 30, 2018, or December 31, 2017.

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 June 30, 2018, and December 31, 2017, the fair value of our outstanding long-term debt (including the current portion of long-term debt) was approximately $10.5 billion and $11.2 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

As of June 30, 2018, we had $1.5 billion available to draw under our $1.5 billion revolving multi-currency credit facility. The borrowing capacity is reduced by borrowings under our commercial paper program when outstanding. We had no borrowings drawn on this revolving credit facility as of June 30, 2018. The maximum leverage ratio of this facility is 5.25x debt to EBITDA, with a decline to 4.00x debt to EBITDA as of the last day of the fiscal quarter ending December 31, 2020. Subsequent to quarter end, we extended the maturity date of our revolving credit facility by one year to July 7, 2023.

Under the terms of each of our debt facilities, we must comply with certain restrictions. These include customary events of default and specified representations and warranties and covenants, including, among other things, covenants that restrict our ability to incur certain additional priority indebtedness, create or permit liens on assets, or engage in mergers or consolidations. As of June 30, 2018, we were in compliance with all of these restrictions and have met all debt payment obligations. All of our outstanding senior notes as of June 30, 2018, rank pari-passu.

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 in Notes 1 and 17 of the Notes included in our Annual Report and did not significantly change during the first half of 2018, with the exception of early adopting the updated hedge accounting guidance during the second quarter of 2018. The adoption of this guidance did not result in a cumulative adjustment to the opening balance of retained earnings as of January 1, 2018, and did not have any other material effect on our results of operations, financial position or cash flows. All required disclosures under the new guidance are presented below on a prospective basis. See further discussion in Note 2, "New Accounting Pronouncements". As noted in Note 17 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 April 18, 2018, we entered into cross currency swap agreements having a total notional of approximately EUR 404 million ($500.0 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 our $500 million2.25% senior notes due 2020 and associated interest to EUR denominated, which will result in a EUR interest rate to be received at 0.85%. We have designated 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.

Forward Starting Interest Rate Swaps

Forward starting interest rate swaps are instruments we use to manage our exposure to the volatility of the interest rates associated with future interest payments on a forecasted debt issuance. Subsequent to June 30, 2018, we entered into forward starting interest rate swaps with notional amounts totaling $1.5 billion. The forward starting interest rate swaps have an effective date of July 2018 and termination dates of July 2021, May 2022 and July 2026, mirroring the terms of the forecasted debt issuances. Under the agreements we are required to early terminate these swaps at the time we expect to issue the related forecasted debt. We have designated these contracts as cash flow hedges. As a result, the unrealized mark-to-market gains or losses will be recorded to AOCI until termination at which point the realized gain or loss of these swaps at issuance of the hedged debt will be reclassified from AOCI and amortized to interest expense over the term of the hedged debt.

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 table below summarizes our derivative assets and liabilities that were measured at fair value as of June 30, 2018, and December 31, 2017.

We expect net losses of approximately $1 million (pretax) recorded in AOCI as of June 30, 2018, related to cash flow hedges, will be reclassified into earnings within the next 12 months. For derivatives designated in cash flow hedge relationships, the maximum length of time over which forecasted transactions are hedged as of June 30, 2018, is approximately four years.

During the six months endedJune 30, 2018, employer contributions to the defined benefit pension plans were approximately $5 million. Total 2018 employer contributions to the defined benefit plans are expected to be approximately $10 million, based on foreign exchange rates as of June 30, 2018. BRI and BDL contributions to their defined benefit pension plans are not included above, as they are not consolidated in our financial statements.

Additionally, we have adopted the FASB's new guidance related to defined benefit pension and other postretirement plans. Specifically, the new guidance requires us to report only the service cost component in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period; while the other components of net benefit cost are now presented in the unaudited condensed consolidated statements of operations separately from the service cost component and outside of operating income.We have also determined that only service cost will be reported within each operating segment and all other components will be reported within the Corporate segment. See further discussion in Note 2, "New Accounting Pronouncements".

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

Litigation, Environmental and Other Contingencies

Related to litigation, environmental issues and other contingencies, we had $13.9 million and $17.8 million accrued, in aggregate, as of June 30, 2018, and December 31, 2017, respectively. While we cannot predict the eventual aggregate cost for legal, environmental and other matters in which we are currently involved, we believe adequate reserves have been provided for losses that are probable and estimable. Additionally, we believe that any reasonably possible losses in excess of the amounts accrued are immaterial to our unaudited condensed consolidated interim financial statements. Our legal, environmental and other liabilities are discussed in further detail within Part II—Item 8 Financial Statements, Note 19, "Commitments and Contingencies" in our Annual Report and did not significantly change during the first half of 2018.

We are 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.

As a result of receiving a favorable ruling related to our historical indirect tax calculations in Europe, we released a previously recorded indirect tax provision related to our Europe operations during the first quarter of 2017, resulting in a benefit of approximately $50 million, recorded within the excise taxes line item on the unaudited condensed consolidated statement of operations during the quarter ended March 31, 2017. During the second quarter of 2017, we received formal confirmation from the regulatory authority that they would not appeal the local jurisdictional court ruling, and the regulatory authority has since withdrawn its assessments. As a result, we believe this dispute is fully resolved.

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 motions to dismiss and for a preliminary injunction seeking to bar MillerCoors from continuing to use “STONE” on Keystone Light cans and related marketing materials. A hearing relating to the motions to dismiss and preliminary injunction is currently scheduled during the third quarter of 2018. We intend to vigorously assert and defend our rights in this lawsuit. A range of potential loss is not estimable at this time.

Guarantees

We guarantee indebtedness and other obligations to banks and other third parties for some of our equity method investments and consolidated subsidiaries. As of June 30, 2018, and December 31, 2017, the unaudited condensed consolidated balance sheets include liabilities related to these guarantees of $59.8 million and $42.8 million, respectively, primarily related to the guarantee of the indebtedness of our equity method investments. See Note 4, "Investments" for further detail.

Separately, related to our Kaiser indemnities, we have accrued $14.7 million and $17.3 million, in aggregate, as of June 30, 2018, and December 31, 2017, respectively. The maximum potential claims amount remaining for the Kaiser-related purchased tax credits was $90.3 million, based on foreign exchange rates as of June 30, 2018. Our Kaiser liabilities are discussed in further detail within Part II—Item 8 Financial Statements, Note 19, "Commitments and Contingencies" in our Annual Report and did not significantly change during the first half of 2018.

(1) Segment results for the three and six months ended June 30, 2017, have been adjusted to reflect the adoption of the new accounting pronouncement for pension and other postretirement benefit costs as well as the reclassification of all non-service cost components of pension and other postretirement costs to Corporate. See Note 2, "New Accounting Pronouncements" for further details.

(2) During the first quarter of 2017, we received payment and recorded a gain of CAD 10.6 million, or $8.1 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.

(3) During the three months ended March 31, 2017, we recorded a provision for an estimate of uncollectible receivables of approximately$11 millionrelated to Agrokor, a large customer in Croatia. We have subsequently reduced this exposure and as of June 30, 2018, our estimated provision of uncollectible receivables from Agrokor totals approximately $4 million. The settlement plan related to this matter was announced in July 2018. We are currently evaluating the implications of the settlement plan, and do not expect it to have a significant impact on our financial statements upon finalization.Separately, during the first quarter of 2017, we released an indirect tax loss contingency, which was initially recorded in the fourth quarter of 2016, for a benefit of approximately$50 million. See Note 14, "Commitments and Contingencies" for details.

(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 6, "Special Items". Additionally, related to the unrealized mark-to-market valuation on our commodity hedge positions, we recorded an unrealized gain of $45.1 million and an unrealized loss of $39.6 million during the three and six months ended June 30, 2018, respectively, compared to an unrealized loss of $23.4 million and an unrealized gain of $39.7 million during the three and six months ended June 30, 2017, respectively.

(1) Charges for the three and six months ended June 30, 2018, relate to the planned closure of the Colfax, California cidery, and consist primarily of accelerated depreciation in excess of normal depreciation. Charges for the three and six months ended June 30, 2017, relate to the closure of the Eden, North Carolina, brewery.

(2) For the three and six months ended June 30, 2018, we incurred charges consisting primarily of accelerated depreciation in excess of normal depreciation related to the planned closures of the Vancouver and Montreal breweries, which are currently expected to occur in 2019 and 2021, respectively. Charges for the three and six months ended June 30, 2017, relate primarily to accelerated depreciation in excess of normal depreciation related to the above mentioned planned closure of the Vancouver brewery.

(3) For the three and six months ended June 30, 2018, we incurred charges primarily related to the closure of the Burton South brewery, which closed during the first quarter of 2018. For the three and six months ended June 30, 2017, we incurred charges consisting primarily of accelerated depreciation in excess of normal depreciation related to the Burton South brewery closure.

(4) For the three and six months ended June 30, 2018, we incurred charges related to the exit of our China business.

(5) On October 11, 2016, we completed the Acquisition for $12.0 billion in cash, subject to a downward adjustment as described in the purchase agreement. This purchase price "Adjustment Amount," as defined in the purchase agreement, required payment to MCBC if the unaudited EBITDA for the Miller International Business for the twelve months prior to closing was below $70 million.

Throughout the process outlined in the purchase agreement, significant uncertainty remained on the ultimate outcome of the Adjustment Amount. As a result, no adjustment to purchase accounting was made through the completion of the measurement period in October 2017. Subsequently, on January 21, 2018, MCBC and ABI entered into a settlement agreement related to the purchase price adjustment under the purchase agreement, and on January 26, 2018, pursuant to the settlement agreement, ABI paid to MCBC $330.0 million, of which $328.0 million constitutes the Adjustment Amount. 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 within our unaudited condensed consolidated statement of cash flows for the six months ended June 30, 2018. MCBC and ABI also agreed to certain mutual releases as further described in the settlement agreement which was filed as an exhibit to a Current Report on Form 8-K filed January 22, 2018.

(1) The fair value hedges related to these notes have been settled and are being amortized over the life of the respective note.

(2) During the second quarter, we entered into 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 economically converted our $500 million2.25% senior notes due 2020 and associated interest to EUR denominated, which will result in a EUR interest rate to be received at 0.85%. See Note 12, "Derivative Instruments and Hedging Activities" for further details.

(3) As of June 30, 2018, we had $6.9 million in bank overdrafts and $71.6 million in bank cash related to our cross-border, cross-currency cash pool, for a net positive position of $64.7 million. As of December 31, 2017, we had $1.2 million in bank overdrafts and $37.8 million in bank cash related to our cross-border, cross-currency cash pool for a net positive position of $36.6 million. We had total outstanding borrowings of $5.4 million and $3.2 million under our two JPY overdraft facilities as of June 30, 2018, and December 31, 2017, respectively. In addition, we have GBP and CAD lines of credit under which we had no borrowings as of June 30, 2018, or December 31, 2017.
