	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: Molson Coors Canada ("MCC"), operating in Canada; MillerCoors LLC ("MillerCoors"), which is accounted for by us under the equity method of accounting, operating in the United States ("U.S."); Molson Coors Europe, operating in Czech Republic, Serbia, Croatia, Romania, Bulgaria, Hungary, Montenegro, Bosnia-Herzegovina and Slovakia (collectively, "Central Europe"), as well as the United Kingdom ("U.K.") and the Republic of Ireland; Molson Coors International ("MCI"), operating in various other countries. Effective for the first day of our 2013 fiscal year, we combined our U.K. and Ireland business with our Central Europe operations, which resulted in our Europe segment, and we have recast the historical presentation of segment information accordingly.
	Unless otherwise indicated, information in this report is presented in U.S. dollars ("USD" or "$").
	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 accounting principles generally accepted in the United States of America ("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 29, 2012 ("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 ("Notes") included in our Annual Report. Our accounting polices did not change in the third quarter or first three quarters of 2013. The results of operations for the thirteen and thirty-nine weeks ended September 28, 2013, are not necessarily indicative of the results that may be achieved for the full fiscal year.
	We follow a 52/53 week fiscal reporting calendar. Unless otherwise indicated, the third quarter of 2013 and 2012 refers to the thirteen weeks ended September 28, 2013, and September 29, 2012, respectively. The first three quarters of 2013 and 2012 refers to the thirty-nine weeks ended September 28, 2013, and September 29, 2012, respectively. Fiscal year 2013 refers to the 52 weeks ending December 28, 2013, and fiscal year 2012 refers to the 52 weeks ended December 29, 2012.
	MillerCoors and Central Europe follow a monthly reporting calendar. The third quarter and first three quarters of 2013 and 2012 refer to the three and nine months ended September 30, 2013, and September 30, 2012, respectively, except for Central Europe where the first three quarters of 2012 refer to the period from the acquisition date of June 15, 2012 through September 30, 2012.
	Foreign Currency Translation Tax Adjustment
	During the third quarter of 2013, we identified that we had incorrectly recorded tax adjustments related to certain foreign currency movements in the financial statements for both the first and second quarters of 2013 that misstated non-current deferred tax assets, accumulated other comprehensive income (loss), and comprehensive income by immaterial amounts. We will revise foreign currency translation adjustments, net of tax, included in other comprehensive income (loss) and comprehensive income (loss) in the condensed consolidated statement of comprehensive income (loss) for the thirteen weeks ended March 30, 2013, and June 29, 2013, and for the twenty-six weeks ended June 29, 2013, in future filings. The impact of correcting these errors has been presented below and reflected in our condensed consolidated statement of comprehensive income for the thirty-nine weeks ended September 28, 2013. The error does not impact the condensed consolidated statement of comprehensive income (loss) for the thirteen weeks September 28, 2013, or the condensed consolidated balance sheet as of September 28, 2013.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]	'
New Accounting Pronouncements	'
	New Accounting Pronouncements
	Adoption of New Accounting Pronouncements
	Disclosure about Offsetting Assets and Liabilities
	In December 2011, the Financial Accounting Standards Board ("FASB") issued authoritative guidance enhancing the disclosure requirements related to offsetting asset and liability positions. The update creates new disclosure requirements about the nature of an entity's rights of offset and related arrangements associated with its financial instruments and derivative instruments. The new disclosures are designed to better facilitate comparison between financial statements prepared under U.S. GAAP and International Financial Reporting Standards ("IFRS") by requiring entities to provide financial statement users information about both gross and net exposures. The guidance was effective for our quarter ended March 30, 2013. The adoption of this guidance does not have an impact on our financial position or results from operations, although we have included additional disclosure noting that our derivative agreements do not allow us to net positions with the same counterparty and therefore, we present our derivative positions gross in our condensed consolidated balance sheets. See Note 14, "Derivative Instruments and Hedging Activities."
	Reclassification of Items from Accumulated Other Comprehensive Income (Loss)
	In February 2013, the FASB issued authoritative guidance which adds new disclosure requirements for items reclassified out of accumulated other comprehensive income (loss) ("AOCI"). The update requires that an entity present either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of AOCI based on its source and the income statement line items affected by the reclassification. The guidance was effective for our quarter ended March 30, 2013. We have separately disclosed the required information related to reclassification adjustments within Note 13, "Accumulated Other Comprehensive Income (Loss)." The adoption of this guidance does not have an impact on our financial position or results from operations.
	New Accounting Pronouncements Not Yet Adopted
	Joint and Several Liability Arrangements
	In February 2013, the FASB issued authoritative guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. The guidance is effective for annual reporting periods beginning on or after December 15, 2013, and interim reporting periods thereafter. We do not anticipate that this guidance will have an impact on our financial position or results of operations.
	Cumulative Translation Adjustment
	In March 2013, the FASB issued authoritative guidance on a parent's accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. This update will also resolve the diversity in practice for the treatment of business combinations achieved in stages (sometimes also referred to as step acquisitions) involving a foreign entity. The guidance is effective for annual reporting periods beginning on or after December 15, 2013, and interim reporting periods thereafter. We do not anticipate that this guidance will have an impact on our financial position or results of operations.
	Liquidation Basis of Accounting
	In April 2013, the FASB issued authoritative guidance to clarify when it is appropriate to apply the liquidation basis of accounting. Additionally, the update provides guidance for recognition and measurement of assets and liabilities and requirements for financial statements prepared using the liquidation basis of accounting. Under the amendment, entities are required to prepare their financial statements under the liquidation basis of accounting when a liquidation becomes imminent. The guidance is effective for annual reporting periods beginning after December 15, 2013, and interim reporting periods therein. We do not anticipate that this guidance will have an impact on our financial position or results of operations.
	Presentation of Unrecognized Tax Benefits
	In July 2013, the FASB issued authoritative guidance related to the presentation of unrecognized tax benefits. The update requires that the entity present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward or a tax credit carryforward in the statement of financial position. The guidance does not apply to the extent that a net operating loss carryforward or tax credit carryforward at the reporting date is not available under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position. The guidance is effective for annual reporting periods beginning after December 15, 2013, and interim reporting periods thereafter. We expect to present deferred tax assets net of unrecognized tax benefits in the condensed consolidated balance sheets. We do not anticipate that this guidance will have a material impact on our financial position or results of operations.

("StarBev") from StarBev L.P. (the "Seller") on June 15, 2012, for €2.7 billion (or $3.4 billion), including the assumption and payoff of pre-existing StarBev indebtedness. Headquartered in Prague, this business is one of the largest brewers in Central Europe. The operating results of Central Europe are reported in our Europe segment and our MCI segment as further described in Note 4, "Segment Reporting." We incurred acquisition and integration costs of $4.4 million and $5.1 million in the third quarters of 2013 and 2012, respectively, and $8.3 million and $36.5 million in the first three quarters of 2013 and 2012, respectively, in connection with the Acquisition. We also incurred financing-related expenses as further described in Note 8, "Other Income and Expense."
	Unaudited Pro Forma Financial Information
	Central Europe contributed net sales of $272.2 million and $676.1 million, of which $264.8 million and $655.2 million is included in our Europe segment, for the third quarter and first three quarters of 2013, respectively. Central Europe contributed losses from continuing operations before income taxes of $88.6 million and $49.7 million, of which $92.1 million and $59.4 million is included in our Europe segment, for the third quarter and first three quarters of 2013, respectively. This compares to contributed net sales of $270.9 million and $328.2 million, of which $264.2 million and $321.5 million is included in our Europe segment, for the third quarter and first three quarters of 2012, respectively. Central Europe contributed income from continuing operations before income taxes of $78.0 million and $90.4 million, of which $75.2 million and $87.6 million is included in our Europe segment, for the third quarter and first three quarters of 2012, respectively. The incremental portion not included in our Europe segment results is our Central Europe export and license business reflected in our MCI segment results effective July 1, 2012. The following unaudited pro forma summary presents our condensed consolidated statements of operations as if Central Europe had been acquired on December 26, 2010, the first day of our 2011 fiscal year. These amounts were calculated after conversion of StarBev's historical operating results to U.S. GAAP, conforming to our accounting policies, and adjusting StarBev's results to reflect the depreciation and amortization that would have been charged assuming the fair value adjustments to properties and other intangibles resulting from the purchase had it been applied from December 26, 2010, together with the consequential tax effects. These adjustments also reflect the removal of StarBev historical interest expense on debt that was repaid at the time of the Acquisition, the addition of interest expense to be prospectively incurred on the debt issued to finance the Acquisition and the removal of the previously mentioned acquisition-related costs of $31.4 million incurred in the first half of 2012. Additional significant adjustments for 2012 include the removal of the following non-recurring, transaction-related costs included in the historical operating results: a $57.9 million Euro currency loss, a $39.2 million loss related to standard pre-issuance U.S. Treasury interest rate hedges ("Treasury Locks"), and bridge facility costs of $13.0 million, as further described in Note 8, "Other Income and Expense" and Note 14, "Derivative Instruments and Hedging Activities", as well as expense of $8.6 million related to the fair value adjustment to acquisition date inventory that was recorded in the post-acquisition condensed consolidated statements of operations. The adjustments recorded in the first half of 2013 upon finalizing purchase accounting, as further described below, did not result in an adjustment to our previously filed pro forma information. These adjustments do not reflect changes in fair value of the embedded conversion feature or foreign exchange movements of the convertible note issued to the Seller as part of the Acquisition. This unaudited pro forma financial information is not intended to reflect the performance which would have actually resulted had the Acquisition been effected on the dates indicated. Further, the unaudited pro forma results of operations are not necessarily indicative of the results of operations that may be obtained in the future.

During the second quarter of 2013 we recorded liabilities in several Central European countries primarily related to local country regulatory matters associated with pre-acquisition periods. Some of these items, if materialized, are subject to various claims with the previous owners of the Central Europe business. We also made adjustments to the brand intangible assets, and related deferred tax impacts, as we completed our brand intangible asset valuation in the second quarter of 2013.

	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 Canada, the U.S., Europe and MCI. Corporate is not a segment and includes interest and certain other general and administrative costs that are not allocated to any of the operating segments.
	Effective for the first day of our 2013 fiscal year, we changed the way in which we monitor performance and manage our operations in Europe and as a result, we combined our U.K. and Ireland business with our Central Europe organization, which resulted in our Europe segment, and we have recast the historical presentation of segment information accordingly.
	No single customer accounted for more than 10% of our consolidated or segmented sales in the third quarter or first three quarters of 2013 or 2012. Net sales represent sales to third-party external customers. Inter-segment sales revenues and income (loss) from continuing operations before income taxes, other than those to MillerCoors (see Note 5, "Investments" for additional detail), are insignificant and eliminated in consolidation.
	Net sales and income (loss) from continuing operations before income taxes below for the first three quarters of 2012, include results from our Central European operations reported within our Europe segment from the Acquisition date of June 15, 2012 through September 29, 2012.

	Our investments include both equity method and consolidated investments. Those entities identified as variable interest entities ("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 September 28, 2013, or December 29, 2012. We have not provided any financial support to any of our VIEs during the quarter 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 September 28, 2013, and December 29, 2012, our consolidated VIEs are Cobra Beer Partnership, Ltd. ("Cobra U.K.") and Grolsch and our unconsolidated VIEs are Brewers' Retail Inc. ("BRI"), Brewers' Distributor Ltd. ("BDL") and Modelo Molson Imports, L.P. ("MMI").

Other Equity Investments
Modelo Molson Imports, L.P.
MMI, a 50%/50% joint venture with Grupo Modelo S.A.B. de C.V. ("Modelo"), imports, distributes, and markets the Modelo beer brand portfolio across all Canadian provinces and territories. Our sales team is responsible for selling the brands across Canada on behalf of the joint venture. We account for MMI, a VIE, under the equity method of accounting.
On November 5, 2013, Anheuser-Busch Inbev ("ABI") and MCBC entered into an agreement providing for the accelerated termination of the MMI joint venture. The joint venture was originally a 10-year agreement ending January 1, 2018. In June 2013, ABI completed its combination with Modelo, including Modelo’s interest in MMI. Following negotiations with ABI, MCC shall receive a CAD 70 million payment in exchange for the consent to change, effective upon closing and the successful completion of the transition period, the termination date in the various joint venture agreements from January 1, 2018 to end of day on February 28, 2014. Similarly, in conjunction with these negotiations, ABI has also agreed that we will continue to represent the Modelo brands in the U.K. and Japan through the end of 2014.
During the transition period, from November 5, 2013 through February 28, 2014, MMI will continue, in its current capacity, to import, distribute, and market the Modelo beer brand portfolio across Canada in the ordinary course. Following the transition period, Modelo will pay us the CAD 70 million early termination payment accelerating the termination of the joint venture to end of day on February 28, 2014. As a result, effective end of day on February 28, 2014, MMI will cease all operations and will ultimately be dissolved. As part of the early termination agreement, the book value of the joint venture’s net assets will then be distributed to the respective joint venture partners for the owners’ proportionate ownership interest. As of September 28, 2013, our condensed consolidated balance sheet includes our investment in MMI of $19.0 million, an affiliate net payable to MMI of $11.8 million and a definite-lived intangible asset of $5.9 million. During the third quarter and first three quarters of 2013, MCC recognized equity earnings of $3.9 million and $9.0 million, respectively, under the MMI arrangement. During the third quarter and first three quarters of 2012, MCC recognized equity earnings of $4.1 million and $11.1 million, respectively. The equity earnings of MMI are recorded within cost of goods sold. In addition to the equity earnings, during the third quarter and first three quarters of 2013, MCC recognized marketing and administrative cost recoveries related to the promotion, sale and distribution of Modelo products under our agency and services agreement with MMI of $3.1 million and $9.0 million, respectively. During the third quarter and first three quarters of 2012, MCC recognized cost recoveries of $3.7 million and $9.5 million, respectively. These cost recoveries are recorded within marketing, general and administrative expenses.

	Share-Based Payments
	During the first three quarters of 2013 and 2012, 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 Molson Coors Brewing Company Incentive Compensation Plan ("Incentive Compensation Plan"): restricted stock units ("RSU"), deferred stock units ("DSU"), performance share units ("PSU"), performance units ("PU") and stock options. As part of our annual grant in the first quarter of 2013, we issued PSUs in place of PUs that had previously been granted in each of the past three years. The settlement amount of the PSUs is determined based on market and performance metrics, which include our total shareholder return performance relative to the S&P 500 and specified adjusted earnings per share. PSU compensation expense is based on a fair value assigned to the market metric using a Monte Carlo model, which will remain constant throughout the vesting period of three years, and a performance multiplier, which will vary due to changing estimates of adjusted earnings per share.
	The following table summarizes share-based compensation expense:


		Thirteen Weeks Ended								Thirty-Nine Weeks Ended
		September 28, 2013				September 29, 2012				September 28, 2013			September 29, 2012

	After-tax compensation expense	$	2.4			$	3.8			$	13.3		$	10.8

	The increase in expense during the first three quarters of 2013 was primarily driven by accelerated expense related to certain RSUs and PSUs granted in the first quarter of 2013.
	As of September 28, 2013, there was $22.4 million of total unrecognized compensation cost from all share-based compensation arrangements granted under the Incentive Compensation Plan, related to unvested shares. This compensation expense is expected to be recognized over a weighted-average period of 1.2 years.
	The following table represents the summary of stock options and stock-only stock appreciation rights ("SOSAR") outstanding as of September 28, 2013, and the activity during the first three quarters of 2013:

	The total intrinsic values of stock options exercised during the first three quarters of 2013 and 2012 were $28.1 million and $13.0 million, respectively. During the first three quarters of 2013 and 2012, cash received from stock option exercises was $74.9 million and $27.4 million, respectively, and the total tax benefit for the tax deductions from these stock option exercises and other awards was $6.0 million and $4.2 million, respectively.

	The fair value of each option granted in the first three quarters of 2013 and 2012 was determined on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:


		Thirty-Nine Weeks Ended
		September 28, 2013		September 29, 2012
	Risk-free interest rate	1.43%		1.50%
	Dividend yield	2.88%		2.99%
	Volatility range	22.39%-25.90%		25.80%-27.56%
	Weighted-average volatility	25.02%		25.86%
	Expected term (years)	7.7		4.0-7.7
	Weighted-average fair market value	$8.39		$8.09
	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. The range on the expected term in 2012 results from awards granted to separate groups of employees who exhibit different historical exercise behavior.
The fair value of the market metric for each PSU granted in the first quarter of 2013 was determined on the date of grant using a Monte Carlo model to simulate total shareholder return for MCBC and peer companies. This value was calculated at $43.10 using a term of 2.83 years as the time between grant date and the end of the performance period. Specific inputs into this valuation, derived using the specified term include a volatility of 21.13% for MCBC and between a range of 12% and 69% for our peers, a risk-free interest rate of 0.33% and a dividend yield of 2.88%.
As of September 28, 2013, there were 7.8 million shares of the Company's Class B common stock available for issuance as awards under the Incentive Compensation Plan.

	-1	During 2013 and 2012, we recognized expenses associated with restructuring programs focused on labor savings and organizational effectiveness across all functions. As a result, we have reduced headcount by approximately 740 employees since the start of 2012.

	-2	During the third quarter and first three quarters of 2013 and 2012, we recognized charges related to special termination benefits as eligible employees elected early retirement offered as a result of the ratification of collective bargaining agreements with MCC's brewery groups.

	-3	During the second quarter of 2012, we recognized an asset abandonment charge related to the discontinuation of primary packaging in the U.K. We determined that our Home Draft package was not meeting expectations driven by a lack of demand in the U.K. market and as a result, we recognized a loss related to the write-off of the Home Draft packaging line, tooling equipment and packaging materials inventory.

	-4	During the third quarter of 2013, we recognized impairment charges related to indefinite-lived intangible assets in Europe. See Note 11, "Goodwill and Intangible Assets" for further discussion.

	-5	In the second quarter of 2012, we recognized impairment charges related to goodwill and definite-lived intangible assets in our joint venture in China. See Note 11, "Goodwill and Intangible Assets" for further discussion. In the third quarter of 2012, we deconsolidated our MC Si'hai joint venture in China due to a loss of our ability to control the joint venture and recognized an impairment loss of $27.6 million upon deconsolidation and $0.9 million of related costs.

	-6	In the third quarter of 2012, we incurred expenses in excess of insurance proceeds related to flood damage at our Toronto offices. In the first three quarters of 2012, we received insurance proceeds in excess of expenses incurred related to these damages.

	-7	During the third quarter and first three quarters of 2013, we recorded losses and related costs of $2.6 million and $5.9 million, respectively, in our Europe business related to significant flooding in Czech Republic in the second quarter of 2013. These losses were offset by $3.3 million insurance proceeds received in the second quarter of 2013.

	-8	During 2009, we established a non-income-related tax reserve of $10.4 million that was recorded as a special item. The amounts recorded in 2013 and 2012 represent the release of this reserve as a result of a change in estimate. As a result, the remaining amount of this non-income-related tax reserve was fully released in the first quarter of 2013.

	-1	We incurred costs in connection with the issuance and subsequent termination of the bridge loan agreement entered into concurrent with the announcement of the Acquisition during the second quarter of 2012.

	-2	In connection with the Acquisition, we used the proceeds from our issuance of the $1.9 billion senior notes to purchase Euros. As a result of an unfavorable foreign exchange movement between the Euro and USD prior to using these proceeds to fund the Acquisition, we realized a foreign exchange loss on our Euro cash holdings during the second quarter of 2012.

	-3	During the first quarter of 2013, we realized a gain for proceeds received related to a non-income-related tax settlement resulting from historical activity within our former investment in the Montreal Canadiens.

	-4	Included in this amount are losses of $11.4 million and $1.4 million for the third quarter and first three quarters of 2013, respectively, and losses of $6.4 million and $5.8 million for the third quarter and first three quarters of 2012, respectively, related to foreign currency movements on foreign-denominated financing instruments entered into in conjunction with the closing of the Acquisition. We additionally recorded a net gain of $1.8 million and loss of $4.9 million for the third quarter and first three quarters of 2013, respectively, related to foreign cash positions and foreign exchange contracts entered into to hedge our risk associated with the payment of this foreign-denominated debt. See Note 12, "Debt" and Note 14, "Derivative Instruments and Hedging Activities" for further discussion of financing and hedging activities related to the Acquisition. Additionally, we recorded gains of $4.3 million and losses of $5.1 million related to other foreign exchange and derivative activity during the third quarter and first three quarters of 2013, respectively. We recorded losses related to other foreign exchange and derivative activity of $2.9 million for the first three quarters of 2012.

	Our effective tax rates for the third quarters of 2013 and 2012 were approximately 21% and 17%, respectively. For the first three quarters of 2013 and 2012, our effective tax rates were approximately 14% and 18%, respectively. The third quarter 2013 tax rate increased versus 2012 primarily due to lower pretax income in 2013, and discrete period tax expenses recorded in 2013 that did not exist in 2012. The tax expenses recorded discretely in the third quarter included the impact of statutory tax rate changes. Additionally, the third quarter year-to-date 2013 tax rate decreased versus 2012 due primarily to the favorable resolution of unrecognized tax positions related to Canada tax law changes enacted in the second quarter of 2013.
	Our tax rate is volatile and may move up or down with changes in, among other things, the amount and source of income or loss, our ability to utilize foreign tax credits, changes in tax laws, and the movement of liabilities established for uncertain tax positions as statutes of limitations expire or positions are otherwise effectively settled. There are proposed or pending tax law changes in various jurisdictions that, if enacted, may have an impact on our effective tax rate.
	As of September 28, 2013, and December 29, 2012, we had unrecognized tax benefits including interest, penalties and offsetting positions of $81.5 million and $82.1 million, respectively. For the first three quarters of 2013, our unrecognized tax benefits decreased due to changes in Canada tax law. This decrease was primarily offset by adjustments to our unrecognized tax benefits in Europe upon finalization of purchase accounting related to the Acquisition. The allocation of these balances between current and noncurrent has not changed materially since December 29, 2012.

	Convertible Notes
	In June 2007, we issued $575 million of senior convertible notes due July 2013. On July 30, 2013, these notes matured and were repaid for their face value of $575 million. The required premium payment, based on our weighted-average Class B common stock price exceeding the then-applicable conversion price on any of the 25 trading days following the maturity date, was settled in cash and entirely offset by the cash proceeds received from the settlement of the call options we purchased in 2007 related to these notes. As a result, these notes and related call options did not impact our shares outstanding. Additionally, the potential impacts of these notes and related call options had no impact on diluted income per share for all periods presented. The impact of stock that could be issued to settle share obligations we could have under the warrants we issued simultaneously with the issuance of these notes will begin to dilute earnings per share when our Class B common stock price reaches $66.13 per share. The warrants expire beginning December 2013 through February 2014. See Note 12, "Debt" for further discussion.
	Upon closing of the Acquisition in June 2012, we issued a €500 million Zero Coupon Senior Unsecured Convertible Note to the Seller. On August 13, 2013, the Seller exercised the embedded put option and we subsequently settled the note using cash. As a result, the convertible note did not impact our shares outstanding and was excluded from the computation of the effect of diluted securities on diluted earnings per share for all periods presented. See Note 12, "Debt" for further discussion.

	-1	During the second quarter of 2013, we finalized purchase accounting related to the Acquisition with a resulting reduction to Europe goodwill in the first half of 2013 of $15.4 million. We assigned the majority of the goodwill resulting from the Acquisition to our Europe reporting unit with a portion allocated to the Canada reporting unit resulting from synergies. The allocation of goodwill to our Canada reporting unit was not impacted by the changes made in the first half of 2013 and is now final. See Note 3, "Acquisition of StarBev" for further discussion.

The changes in the gross carrying amounts of intangibles from December 29, 2012, to September 28, 2013, are driven by the impact of foreign exchange rates, as a significant amount of intangibles are denominated in foreign currencies, the indefinite-lived brand intangible impairments recorded in the third quarter of 2013, the change in classification of the Ostravar brand from an indefinite life to a useful life subject to amortization, as well as the adjustments recorded on brand intangible assets during the first half of 2013 related to the finalization of the purchase price allocation. See Note 3, "Acquisition of StarBev" for further discussion.
Based on foreign exchange rates as of September 28, 2013, the estimated future amortization expense of intangible assets is as follows:


Fiscal year	Amount
	(In millions)
2013 - remaining	$	12.4

2014	$	41.2

2015	$	38.6

2016	$	38.6

2017	$	25

Amortization expense of intangible assets was $12.1 million and $11.8 million for the third quarters of 2013 and 2012, respectively, and $35.7 million and $30.4 million for the first three quarters of 2013 and 2012, respectively. This expense is presented within marketing, general and administrative expenses.
We completed our required annual goodwill and indefinite-lived intangible impairment testing as of June 30, 2013, the first day of our fiscal third quarter, and concluded there were no impairments of goodwill within our Europe, Canada or India reporting units or impairments of our indefinite-lived intangible assets, with the exception of the Jelen and Ostravar brand intangibles as discussed below.
Reporting Units and Goodwill
Given the change in our operating segments effective the first day of our fiscal year 2013 to combine our U.K. and Ireland business with our Central Europe organization, which resulted in a single European segment, we re-evaluated our reporting units during the first quarter of 2013. This re-evaluation resulted in an aggregation of our U.K. and Central Europe businesses into one Europe reporting unit during the first quarter of 2013 and for purposes of our 2013 annual impairment test. As part of this re-evaluation, we also determined that a goodwill impairment trigger did not exist at either of the previous U.K. or Central Europe reporting unit levels prior to or upon aggregation. Our annual goodwill impairment testing determined that our Europe and Canada reporting units were at risk of failing step one of the goodwill impairment test. Specifically, the fair value of the Europe and Canada reporting units were estimated at approximately 11% and 16% in excess of carrying value, respectively. The risk in the Europe reporting unit is due to continued adverse impacts of a weak economy in Europe partially offset by the realized benefits of combining our U.K. and Central Europe businesses. The Canada reporting unit had a marginal improvement over the prior year primarily as a result of incremental anticipated cost savings and improvements to market multiples more than offsetting the continued competitive pressures and challenging macroeconomic conditions in the Canada market.
During the second quarter of 2012, we recorded an impairment charge for the full amount of our China reporting unit goodwill and definite-lived intangible assets of $9.5 million and $0.9 million, respectively, recorded as special items in our condensed consolidated statements of operations.
Indefinite-Lived Intangibles

In 2013, our annual indefinite-lived intangible impairment testing determined that the fair values of the Jelen and Ostravar indefinite-lived brand intangibles within our Europe segment were below their respective carrying values. As a result, we recorded an aggregate impairment charge of $150.9 million recorded within special items in our condensed consolidated statements of operations in the third quarter of 2013. The impairment of Jelen was primarily the result of increased competition, reduced market share and macroeconomic difficulties driving decreased projected cash flows, as well as unfavorable discount rate and income tax rate movements within Serbia. The impairment of Ostravar was primarily the result of decreased projected cash flows driven by recent economic challenges within the Ostrava region of Czech Republic. These changes in assumptions, driven by adverse economic and competitive factors specific to the markets in which these brands perform, have outpaced forecasted macroeconomic recoveries, resulting in the impairments. The remaining Europe indefinite-lived brand intangibles' fair values, while facing similar macroeconomic challenges, were sufficiently in excess of their respective carrying values, with the exception of two brands acquired in the Acquisition. Specifically, these two brands, Ozujsko in Croatia and Branik in Czech Republic, are at risk of future impairment as a result of discount rate pressures due to country specific macroeconomic risk factors that are currently more than offset by improved cash flow projections driven by post-Acquisition performance and innovations. The Jelen, Ozujsko and Branik brands are therefore at risk of future impairment with an aggregate fair value estimated at approximately 1% in excess of their aggregate carrying value ($1,296.0 million as of September 28, 2013).

Additionally, in conjunction with the brand impairment tests, we also reassessed each brand's indefinite-life classification and determined that the indefinite life classification could no longer be supported for the Ostravar brand. The Ostravar brand has therefore been reclassified as a definite-lived intangible asset and the remaining fair value of the asset will be amortized over its estimated remaining life of approximately 29 years.

Separately, our Molson core brand intangible continues to be at risk of future impairment with a fair value currently estimated at approximately 10% in excess of its carrying value ($2,945.8 million as of September 28, 2013) as the Molson core brands have continued to face significant competitive pressures and challenging macroeconomic conditions in the Canada market. These challenges have been partially offset by anticipated cost savings initiatives.

We utilized Level 3 fair value measurements in our impairment analysis of our indefinite-lived intangible assets, which utilizes an excess earnings approach to determine the fair values of the assets as of the testing date. The future cash flows used in the analysis are based on internal cash flow projections based on our long range plans and include significant assumptions by management as noted below.

Key Assumptions
The Europe and Canada reporting units' goodwill, the Molson core brand intangible, and certain indefinite-lived brand intangibles within Europe are at risk of future impairment in the event of significant unfavorable changes in the forecasted cash flows (including significant delays in projected macroeconomic recovery or prolonged adverse economic conditions), terminal growth rates, market transaction multiples and/or weighted-average cost of capital utilized in the discounted cash flow analysis. For testing purposes, management's best estimates of the expected future results are the primary driver in determining the fair value. Current projections used for our Europe reporting unit and indefinite-lived intangible testing reflect continued challenging environments in the near future followed by growth resulting from a longer term recovery of the macroeconomic environment, as well as the benefit of anticipated cost savings and specific brand-building and innovation activities. Our Canada reporting unit and Molson core brand projections also reflect a continued challenging environment that has been adversely impacted by a weak economy across all industries, as well as weakened consumer demand, partially offset by anticipated cost savings and specific brand-building and innovation activities. Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of the annual goodwill and indefinite-lived intangible impairment test will prove to be an accurate prediction of the future. Examples of events or circumstances that could reasonably be expected to negatively affect the underlying key assumptions and ultimately impact the estimated fair value of our Europe reporting unit, Molson core brand, and the at-risk European brands may include such items as: (i) a decrease in expected future cash flows, specifically, an increase in required pension contributions, a decrease in sales volume driven by a prolonged weakness in consumer demand or other competitive pressures adversely affecting our long term volume trends, unfavorable working capital changes and an inability to successfully achieve our cost savings targets, (ii) an economic recovery that significantly differs from our assumptions in timing and/or degree, (iii) volatility in the equity and debt markets which could result in a higher discount rate; and (iv) sensitivity to market transaction multiples.
While historical performance and current expectations have resulted in fair values of our reporting units 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.
Regarding definite-lived intangibles, we continuously monitor the performance of the underlying asset for potential triggering events suggesting an impairment review should be performed. No such triggering events were identified in the third quarter of 2013. However, recent litigation related to the licensing agreement with Miller in Canada, for which we have a definite-lived intangible asset with a carrying value of $60.8 million as of September 28, 2013, could result in a possible future impairment. See Note 16, "Commitments and Contingencies" for further discussion.

	-1	Our $575 million convertible notes matured and were repaid on July 30, 2013, for their face value of $575 million. The required premium payment of $2.6 million, which was based on our weighted-average Class B common stock price exceeding the then-applicable conversion price on any of the 25 trading days following the maturity date, was paid in September 2013. This premium was hedged by call options that mitigated our exposure to increases in our stock price and resulted in proceeds of $2.6 million from these call options in September 2013, which fully offset the premium payment. Separately, the warrants entered into concurrent with these call options, pursuant to which we may be required to issue Class B common stock to the counterparty when our stock price reaches $66.13 per share, remain outstanding and will expire beginning December 2013 through February 2014. The original conversion price for each $1,000 aggregate principal amount of notes was $54.76 per share of our Class B common stock, which represented a 25% premium above the stock price on the day of issuance of the notes and corresponded to the initial conversion ratio of 18.263 shares per each $1,000 aggregate principal amount of notes. The conversion ratio and conversion price were subject to adjustments for certain events and provisions, as defined in the indenture, including adjustments reflected for exceeding defined thresholds related to our dividend payments. At the maturity date our conversion price and ratio were $51.8284 and 19.2944 shares, respectively.
	During the third quarters of 2013 and 2012, we incurred additional non-cash interest expense of $1.6 million and $4.5 million, respectively. For the first three quarters of 2013 and 2012, the amounts were $10.9 million and $13.5 million, respectively. We also incurred interest expense related to the 2.5% convertible coupon rate of $1.2 million and $3.6 million during the third quarters of 2013 and 2012, respectively. For the first three quarters of 2013 and 2012, the interest expenses incurred were $8.4 million and $10.8 million, respectively. The combination of non-cash and cash interest resulted in an effective interest rate of 5.75% and 5.78% for the third quarters of 2013, through settlement, and 2012, respectively. The effective interest rates for the first three quarters of 2013, through settlement, and 2012 were 5.73% and 5.79%, respectively. As of September 28, 2013, there was no unamortized debt discount outstanding as we recorded the remaining discount of $1.6 million upon maturity in the third quarter of 2013. As of December 29, 2012, $10.8 million of the unamortized debt discount related to our $575 million convertible debt.

	-2	On June 15, 2012, we issued a €500 million Zero Coupon Senior Unsecured Convertible Note due December 31, 2013 (the ''Convertible Note'') to the Seller in conjunction with the closing of the Acquisition. The Seller had the ability to exercise a put right with respect to the Convertible Note as of March 14, 2013, (the “First Redemption Date”) and ending on December 19, 2013, for the greater of the principal amount of the Convertible Note or the aggregate cash value of 12,894,044 shares of our Class B Common Stock, as adjusted for certain corporate events. In accordance with these terms, on August 13, 2013, the Seller exercised the conversion feature for an agreed upon value upon exercise of €510.9 million, consisting of €500 million in principal and €10.9 million for the conversion feature. At issuance, the total value of the Convertible Note was €511.1 million, consisting of the principal (€500 million), discount (€1.0 million), and conversion feature (€12.1 million), initially recorded as a component of the purchase price associated with the Acquisition.
	Separate from the Seller's notice to put, we have made claims with regard to the representations and warranties provided to us upon close of the Acquisition. As a result, we have withheld €44.9 million ($60.8 million as of September 28, 2013) from the €500 million in principal related to these outstanding claims. The remaining balance continues to be classified as current portion of long-term debt pending the resolution of these claims. Therefore, on September 3, 2013, we paid the seller in cash a total of €466.0 million ($614.7 million) consisting of €455.1 million ($600.3 million) in principal and €10.9 million ($14.4 million) for the conversion feature.
	The Convertible Note's embedded conversion feature was determined to meet the definition of a derivative required to be bifurcated and separately accounted for at fair value with changes in fair value recorded in earnings. During the third quarter and first three quarters of 2013, we recognized a net gain of $20.3 million and a loss of $6.5 million, respectively, on the conversion feature primarily related to the change from the previously recorded fair value to the value upon exercise. The Convertible Note was issued at a discount of $1.3 million, which has been recognized as interest expense over the period from issuance to the First Redemption Date. The non-cash interest, excluding the change in fair value of the convertible feature, resulted in an immaterial impact to our effective interest rate for the third quarter and first three quarters of 2013. See Note 14, "Derivative Instruments and Hedging Activities" for further discussion.

	-3	During the third quarter and first three quarters of 2013, we made principal repayments of $71.8 million (€53.7 million) and $123.8 million (€93.7 million), respectively, on the remaining balance of our €120 million term loan. As a result, the term loan, which was designated as a net investment hedge, was fully repaid in the third quarter of 2013. See Note 14, "Derivative Instruments and Hedging Activities" for further discussion.

	-4	In the first quarter of 2013, a $950 million commercial paper program was approved and implemented. The commercial paper program is supported by our $550 million and $400 million revolving credit facilities. To fund the repayment of our €500 million Zero Coupon Senior Unsecured Convertible Note, we issued short-term commercial paper during the third quarter of 2013. As of September 28, 2013, the outstanding borrowings under the commercial paper program were $391.1 million.
	In the third quarter of 2012, we entered into a 1-year, €150 million revolving credit agreement, on an uncommitted basis, to support our operations in Central Europe within our Europe segment. In the third quarter of 2013, this revolving credit facility was renewed and restructured and will continue to provide €150 million on an uncommitted basis through September 2014. As of September 28, 2013, the outstanding borrowings under this revolving credit facility were $162.3 million. There were no outstanding borrowings under this revolving credit facility as of December 29, 2012.
	In the second quarter of 2012, we entered into a 4-year, $550 million revolving credit agreement. This credit agreement contains customary events of default and specified representations and warranties and covenants, including, among other things, covenants that limit our subsidiaries' ability to incur certain additional priority indebtedness, create or permit liens on assets, or engage in mergers or consolidations. As of September 28, 2013, and December 29, 2012, there were no outstanding borrowings under this revolving credit facility.
	In the second quarter of 2011, we entered into an agreement for a 4-year, $400 million revolving multicurrency credit facility, which provides a $100 million sub-facility available for the issuance of letters of credit. As of September 28, 2013 and December 29, 2012, there were no outstanding borrowings under this revolving credit facility.
	The remaining outstanding balances as of September 28, 2013, and December 29, 2012, relate to other short-term borrowings.
	Debt Fair Value Measurements
	We utilize market approaches to estimate the fair value of certain outstanding borrowings by discounting anticipated future cash flows derived from the contractual terms of the obligations and observable market interest and foreign exchange rates. As of September 28, 2013, and December 29, 2012, the fair value of our outstanding long-term debt (including current portion) was $3,410.4 million and $4,993.0 million, respectively. Our €120 million term loan, which was repaid in the third quarter 2013, and all senior notes are valued based on significant observable inputs and would be classified as Level 2 in the fair value hierarchy. The fair value measurement of the conversion feature embedded in the Convertible Note included significant unobservable inputs and was classified as Level 3 in the fair value hierarchy prior to settlement. See Note 14, "Derivative Instruments and Hedging Activities" for further discussion regarding the fair value and settlement of the conversion feature related to the Convertible Note. The carrying values of all other outstanding long-term borrowings and our short-term borrowings approximate their fair values.
	Other
	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 September 28, 2013, and December 29, 2012, we were in compliance with all of these restrictions and have met all debt payment obligations.

	-1	During the first quarter of 2013, we recorded a tax adjustment related to the reclassification of amounts from the investment in MillerCoors to AOCI that was recorded in the fourth quarter of 2012 to reflect our proportional share of MillerCoors AOCI at formation. We made this reclassification in 2012 as we believe the new presentation provides improved transparency of our share of MillerCoors AOCI. This tax adjustment, which should have been made in 2012 with the reclassification, was not material to either the current or prior period financial statements taken as a whole and therefore prior periods do not reflect the adjustment.

	-2	During the third quarter of 2013, we identified that we had incorrectly recorded tax adjustments related to certain foreign currency movements in the financial statements for both the first and second quarters of 2013. See Note 1, "Basis of Presentation and Summary of Significant Accounting Policies" for further discussion.

	Reclassifications from AOCI to income for the third quarter and first three quarters of 2013 were as follows:

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 18 of the Notes included in our Annual Report and did not significantly change during the first three quarters of 2013. As noted in Note 18 of the Notes included in our Annual Report, due to the nature of our counterparty agreements, and 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 gross in our condensed consolidated balance sheets. Our significant derivative/hedge positions have not changed significantly since year-end, except as noted below.
	Significant Derivative/Hedge Positions
	Derivative Activity Related to the Acquisition
	In the first quarter of 2013, we began executing a series of financial foreign exchange forward contracts to hedge our risk associated with payments of our Euro-denominated Convertible Note issued to the Seller simultaneous with the closing of the Acquisition in June 2012. The Convertible Note was put to us in the third quarter of 2013. The related conversion feature was settled in full and therefore is no longer outstanding as of September 28, 2013. As a result of the settlement all existing foreign exchange forward contracts related to the Convertible Note were settled in the third quarter of 2013. These contracts were not designated in hedge accounting relationships. As such, changes in fair value of these swaps were recorded in other income (expense) in our condensed consolidated statement of operations.
	On April 3, 2012, we entered into a 4-year, €120 million term loan agreement, which was funded upon close of the Acquisition on June 15, 2012. In the third quarter of 2012, we designated the term loan as a net investment hedge of our Central European operations. In the third quarter of 2013, we repaid the outstanding balance on this term loan.
	Cross Currency Swaps
	In each of the second and third quarters of 2013, we cash settled CAD 100 million notional of our outstanding cross currency swaps designated as a net investment hedge of our Canadian operations for $31.4 million and $31.1 million, respectively. The remaining outstanding cross currency swaps are due to mature March 31, 2014, and were in a net liability position of $134.0 million as of September 28, 2013. Early in the fourth quarter of 2013 we cash settled an additional CAD 161 million notional of this remaining position for $51.4 million.
	Commodity Swaps
	In 2013 we entered into financial commodity swap contracts to hedge our exposure to changes in the prices of corn and aluminum, including surcharges relating to our aluminum exposures. These contracts allow us to swap our floating exposure to changes in these commodity prices for a fixed rate. These contracts are not designated in hedge accounting relationships. As such, changes in fair value of these swaps are recorded in cost of goods sold in the condensed consolidated statements of operations.
	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. The table below summarizes our derivative assets and liabilities that were measured at fair value as of September 28, 2013, and December 29, 2012.

	The following tables present additional information about Level 3 assets and liabilities measured at fair value on a recurring basis for the quarter ended September 28, 2013. Both observable and unobservable inputs may be used to determine the fair value of positions that we have classified within the Level 3 category. As a result, the unrealized gains (losses) during the period for assets and liabilities within the Level 3 category presented in the tables below may include changes in fair value during the period that were attributable to both observable (e.g., changes in market interest rates) and unobservable (e.g., changes in unobservable long-dated volatilities) inputs.
	The table below summarizes derivative valuation activity using significant unobservable inputs (Level 3):

We had no significant transfers between Level 1 and 2 during the third quarter or first three quarters of 2013. As of December 29, 2012, the conversion feature related to the Convertible Note was classified as a Level 3 derivative due to valuations based upon significant unobservable inputs. The Convertible Note was put to us in the third quarter of 2013 and as a result, we settled the remaining balance associated with the conversion feature which was historically included within Level 3 derivatives. As of September 28, 2013, we have no outstanding derivatives classified as Level 3. New derivative contracts transacted during the third quarter and first half of 2013 were all included in Level 2.

Commitments and Contingencies Disclosure [Abstract]	'

	Discontinued Operations
	Kaiser
	In 2006, we sold our entire equity interest in our Brazilian unit, Cervejarias Kaiser Brasil S.A. ("Kaiser") to FEMSA Cerveza S.A. de C.V. ("FEMSA"). The terms of the sale agreement require us to indemnify FEMSA for exposures related to certain tax, civil and labor contingencies arising prior to FEMSA's purchase of Kaiser. In addition, we provided an indemnity to FEMSA for losses Kaiser may incur with respect to tax claims associated with certain previously utilized purchased tax credits. The discontinued operations balances within the current and non-current liabilities of our condensed consolidated balance sheets consist entirely of our estimates of these liabilities. These liabilities are denominated in Brazilian Reais and are therefore subject to foreign exchange gains or losses, which are recognized in the discontinued operations section of the condensed consolidated statement of operations. There have been no changes in the underlying liabilities from the year ended December 29, 2012, therefore all changes in the current and non-current liabilities of discontinued operations during the first three quarters of 2013 are due to fluctuations in foreign exchange rates from December 29, 2012, to September 28, 2013. In the third quarters of 2013 and 2012, we recognized gains of $0.9 million and $1.2 million, respectively, from discontinued operations associated with foreign exchange gains and losses related to indemnities we provided to FEMSA. During the first three quarters of 2013 and 2012, we recognized foreign exchange gains of $1.7 million and $3.6 million, respectively. Our exposure related to the tax, civil and labor indemnity claims is capped at the amount of the sales price of the 68% equity interest of Kaiser, which was $68.0 million. Separately, the maximum potential claims amount remaining for the purchased tax credits was $155.1 million as of September 28, 2013.
	Future settlement procedures and related negotiation activities associated with these contingencies are largely outside of our control. Due to the uncertainty involved with the ultimate outcome and timing of these contingencies, significant adjustments to the carrying values of the indemnity obligations have been recorded to date, and additional future adjustments may be required.
	Distributorship Litigation
	During the third quarter and first three quarters of 2012, we recognized losses of $0.5 million and $2.0 million, respectively, related to the settlement of a distributorship litigation, which was settled in the third quarter of 2012 for $6.8 million.
	Guarantees
	We guarantee indebtedness and other obligations to banks and other third parties for some of our equity method investments and consolidated subsidiaries.
	Rocky Mountain Metal Container ("RMMC"), a Colorado limited liability company, is a joint venture with Ball Corporation in which MillerCoors holds and consolidates a 50% interest. As of September 28, 2013, and December 29, 2012, we guaranteed $4.5 million of RMMC debt, which is due in the fourth quarter of 2013.
	Related to our previous ownership in the Montréal Canadiens, we guarantee its obligations under a ground lease for the Bell Centre Arena (the "Ground Lease Guarantee"). Upon sale of our interest, the new owners agreed to indemnify us in connection with the liabilities we may incur under the Ground Lease Guarantee and provided us with a CAD 10 million letter of credit to guarantee such indemnity. This transaction did not materially affect our risk exposure related to the Ground Lease Guarantee, which continues to be recognized as a liability on our balance sheet.
	Related to guarantees, other liabilities in the accompanying condensed consolidated balance sheets include $6.0 million as of September 28, 2013, and $6.2 million as of December 29, 2012, both of which are non-current.
	Litigation and Other Disputes and Environmental
	Related to litigation, other disputes and environmental issues, we have accrued an aggregate of $13.8 million as of September 28, 2013, and $14.5 million as of December 29, 2012. We believe that any reasonably possible losses in excess of the amounts accrued are immaterial to our condensed consolidated financial statements.
	In addition to the specific cases discussed below, we are involved in other disputes and legal actions arising in the ordinary course of our business. Additionally, during the first quarter of 2013 we became aware of potential liabilities in several Central European countries primarily related to local country regulatory matters. See Note 3, "Acquisition of StarBev" for further discussion. 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 is 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.
	While we cannot predict the eventual aggregate cost for environmental and related matters in which we are currently involved, we believe that any payments, if required, for these matters would be made over a period of time in amounts that would not be material in any one year to our results from operations, cash flows or our financial or competitive position. We believe adequate reserves have been provided for losses that are probable and estimable.
	Litigation and Other Disputes
	In December 2012, Miller Brewing Company (“Miller”) orally informed us of its intent to terminate the license agreement between Miller and us whereby we have exclusive rights to distribute certain Miller products in Canada (the “License Agreement”) including Miller Lite, Miller High Life, Milwaukee's Best, Mickey's, Olde English, Miller Genuine Draft, and Miller Chill. Miller alleges that we failed to meet certain volume sales targets under the License Agreement. We do not believe Miller has any right under the License Agreement or otherwise to terminate the License Agreement. Following this communication, we filed a lawsuit in Ontario, Canada (Molson Canada 2005 v. Miller Brewing Company, Sup. Ct. of Justice-Ontario, CV-12-470589) seeking an injunction preventing Miller from terminating the License Agreement and ordering Miller to abide by its contractual terms. On January 18, 2013, Miller sent written notice to us purporting to terminate the License Agreement. In our lawsuit, we also assert that Miller breached the License Agreement by attempting to terminate the License Agreement. On June 20, 2013, we were granted an injunction preventing Miller's termination of the License Agreement, pending a trial on the merits, which is scheduled for December 2013.
	We intend to vigorously assert and defend our rights in this lawsuit. At this time, we are unable to predict the outcome of this litigation or the impact, if any, of an adverse outcome on our business and results of operations, including any possible future asset impairment. We recognized net sales related to the License Agreement of $25.8 million and $31.4 million for the third quarters of 2013 and 2012, respectively, and net sales of $72.9 million and $77.6 million for the first three quarters of 2013 and 2012, respectively. Additionally, as of September 28, 2013, we had a definite-lived intangible asset related to the License Agreement with a carrying value of $60.8 million and a remaining life of approximately 6 years.
	Environmental
	Canada
	Our Canada brewing operations are subject to provincial environmental regulations and local permit requirements. Our Montréal and Toronto breweries have water treatment facilities to pre-treat waste water before it goes to the respective local governmental facility for final treatment. We have environmental programs in Canada including organization, monitoring and verification, regulatory compliance, reporting, education and training, and corrective action.
	We sold a chemical specialties business in 1996. The Company is still responsible for certain aspects of environmental remediation, undertaken or planned, at those chemical specialties business locations. We have established provisions for the costs of these remediation programs.
	United States
	We were previously notified that we are or may be a potentially responsible party ("PRP") under the Comprehensive Environmental Response, Compensation and Liability Act or similar state laws for the cleanup of sites where hazardous substances have allegedly been released into the environment. We cannot predict with certainty the total costs of cleanup, our share of the total cost, the extent to which contributions will be available from other parties, the amount of time necessary to complete the cleanups or insurance coverage.
	Lowry
	We are one of a number of entities named by the Environmental Protection Agency ("EPA") as a PRP at the Lowry Superfund site. This landfill is owned by the City and County of Denver ("Denver") and is managed by Waste Management of Colorado, Inc. ("Waste Management"). In 1990, we recorded a pre-tax charge of $30 million, a portion of which was put into a trust in 1993 as part of a settlement with Denver and Waste Management regarding the then-outstanding litigation. Our settlement was based on an assumed remediation cost of $120 million (in 1992 adjusted dollars). We are obligated to pay a portion of future costs, if any, in excess of that amount.
	Waste Management provides us with updated annual cost estimates through 2032. We review these cost estimates in the assessment of our accrual related to this issue. We use certain assumptions that differ from Waste Management's estimates to assess our expected liability. Our expected liability (based on the $120 million threshold being met) is based on our best estimates available.
	The assumptions used are as follows:

	•	trust management costs are included in projections with regard to the $120 million threshold, but are expensed only as incurred;

	•	income taxes, which we believe are not an included cost, are excluded from projections with regard to the $120 million threshold;

	•	a 2.5% inflation rate for future costs; and

	•	certain operations and maintenance costs were discounted using a 3.16% risk-free rate of return.
	Based on these assumptions, the present value and gross amount of the costs at September 28, 2013, are approximately $2.8 million and $7.3 million, respectively. We did not assume any future recoveries from insurance companies in the estimate of our liability, and none are expected.
	Considering the estimates extend through the year 2032 and the related uncertainties at the site, including what additional remedial actions may be required by the EPA, new technologies and what costs are included in the determination of when the $120 million is reached, the estimate of our liability may change as further facts develop. We cannot predict the amount of any such change, but additional accruals in the future are possible.
	Other
	In prior years, we have been notified by the EPA and certain state environmental divisions that we are a PRP, along with other parties, at the Cooper Drum site in southern California, the East Rutherford and Berry's Creek sites in New Jersey and the Chamblee and Smyrna sites in Georgia. Certain former non-beer business operations, which we discontinued use of and sold (excluding the property of the former Chamblee site) in the mid-1990s, were involved at these sites. Potential losses associated with these sites could increase as remediation planning progresses.
	We are aware of groundwater contamination at some of our properties in Colorado resulting from historical, ongoing, or nearby activities. There may also be other contamination of which we are currently unaware.
	Europe and MCI
	We are subject to the requirements of governmental and local environmental and occupational health and safety laws and regulations within each of the countries in which we operate. Compliance with these laws and regulations did not materially affect our third quarter of 2013 capital expenditures, results of operations or our financial or competitive position, and we do not anticipate that they will do so during the remainder of the year.

	Supplemental Guarantor Information
	For purposes of this Note 17, including the tables, "Parent Guarantor and 2012 Issuer" shall mean MCBC and "Subsidiary Guarantors" shall mean certain U.S., European and Canadian subsidiaries reflecting the substantial operations of each of our U.S. and Canadian segments, as well as our U.K. operations of our European segment.
	SEC Registered Securities
	On May 3, 2012, MCBC issued $1.9 billion of senior notes, in a registered public offering, consisting of $300 million 2.0% senior notes due 2017, $500 million 3.5% senior notes due 2022, and $1.1 billion 5.0% senior notes due 2042. 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 Guarantor. The guarantees are full and unconditional and joint and several.
	On June 15, 2007, MCBC issued $575 million of 2.5% convertible senior notes due July 30, 2013, in a registered public offering. These notes matured and were repaid in cash in the third quarter 2013. See Note 12, "Debt" for further discussion.
	Other Debt
	On September 22, 2005, MC Capital Finance ULC ("MC Capital Finance") issued $1.1 billion of senior notes consisting of $300 million 4.85% U.S. publicly registered notes due 2010 and CAD 900 million 5.0% privately placed notes maturing on September 22, 2015. These CAD 900 million senior notes were subsequently exchanged for substantially identical CAD 900 million senior notes which were quantified by way of a prospectus in Canada. In connection with an internal corporate reorganization, Molson Coors International LP ("MCI LP") was subsequently added as a co-issuer of the CAD 900 million senior notes in 2007. The $300 million senior notes were repaid in 2010. The continuous disclosure requirements applicable to MC Capital Finance in Canada are satisfied through the consolidating financial information in respect of MC Capital Finance, MCI LP and other subsidiary guarantors of the CAD 900 million senior notes as currently presented within the Subsidiary Guarantors column.
	None of our other outstanding debt is publicly registered, and it is all guaranteed on a senior and unsecured basis by the Parent Guarantor and certain Subsidiary Guarantors. These guarantees are full and unconditional and joint and several. See Note 12, "Debt" for details of all debt issued and outstanding as of September 28, 2013.
	Presentation
	During the third quarter of 2013, we identified that we had incorrectly recorded tax adjustments related to certain foreign currency movements in the financial statements for both the first and second quarters of 2013. See Note 1, "Basis of Presentation and Summary of Significant Accounting Policies" for further information. We will revise comprehensive income (loss) attributable to MCBC in the condensed consolidating statement of operations for the thirteen weeks ended March 30, 2013, and June 29, 2013, and for the twenty-six weeks ended June 29, 2013, in future filings. The impact of correcting these errors has been reflected in our condensed consolidating statement of operations for the thirty-nine weeks ended September 28, 2013. This revision resulted in corrections to comprehensive income (loss) attributable to MCBC within the condensed consolidating statement of operations for the Parent Guarantor from $(206.2) million, as previously reported, to $(225.6) million, as adjusted, for the thirteen weeks ended March 30, 2013, $225.9 million, as previously reported, to $191.2 million, as adjusted, for the thirteen weeks ended June 29, 2013, and $19.7 million, as previously reported, to $(34.4) million, as adjusted, for the twenty-six weeks ended June 29, 2013. The error does not impact the condensed consolidating statement of comprehensive income (loss) for the thirteen weeks September 28, 2013, or the condensed consolidating balance sheet as of September 28, 2013.
	During the first quarter of 2013, we identified necessary corrections to our historical treatment of certain intercompany transactions included as a component of the net investment in and advances to subsidiaries within total assets and MCBC stockholders' equity of the Parent Guarantor. While consolidated totals were not impacted, our December 29, 2012, guarantor condensed consolidating balance sheet presented within this note has been adjusted to reflect the impact of this change, which is limited to the Parent Guarantor column. This revision resulted in a reduction to the amounts attributable to the Parent Guarantor for net investment in and advances to subsidiaries from $11,342.2 million as previously reported, to $10,465.2 million as adjusted, with the offsetting adjustment to the "eliminations" column. This resulted in an equal reduction to MCBC stockholders' equity attributable to the Parent Guarantor from $8,843.9 million as previously reported, to $7,966.9 million as adjusted, with the offsetting adjustment to the "eliminations" column. The changes to our historical guarantor condensed consolidating balance sheet are not material to the financial statements taken as a whole for any periods impacted.
	The following information sets forth the condensed consolidating statements of operations for the third quarter and first three quarters of 2013 and 2012, condensed consolidating balance sheets as of September 28, 2013, and December 29, 2012, and condensed consolidating statements of cash flows for the first three quarters of 2013 and 2012. Investments in subsidiaries are accounted for on the equity method; accordingly, entries necessary to consolidate the Parent Guarantor 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.

Schedule of Error Corrections and Prior Period Adjustments	'
	During the third quarter of 2013, we identified that we had incorrectly recorded tax adjustments related to certain foreign currency movements in the financial statements for both the first and second quarters of 2013 that misstated non-current deferred tax assets, accumulated other comprehensive income (loss), and comprehensive income by immaterial amounts. We will revise foreign currency translation adjustments, net of tax, included in other comprehensive income (loss) and comprehensive income (loss) in the condensed consolidated statement of comprehensive income (loss) for the thirteen weeks ended March 30, 2013, and June 29, 2013, and for the twenty-six weeks ended June 29, 2013, in future filings. The impact of correcting these errors has been presented below and reflected in our condensed consolidated statement of comprehensive income for the thirty-nine weeks ended September 28, 2013. The error does not impact the condensed consolidated statement of comprehensive income (loss) for the thirteen weeks September 28, 2013, or the condensed consolidated balance sheet as of September 28, 2013.

Acquisition of StarBev (Tables)	9 Months Ended

Business Acquisition [Line Items]	'
Business Acquisition, Pro Forma Information, Statements of Operations	'
	The following unaudited pro forma summary presents our condensed consolidated statements of operations as if Central Europe had been acquired on December 26, 2010, the first day of our 2011 fiscal year. These amounts were calculated after conversion of StarBev's historical operating results to U.S. GAAP, conforming to our accounting policies, and adjusting StarBev's results to reflect the depreciation and amortization that would have been charged assuming the fair value adjustments to properties and other intangibles resulting from the purchase had it been applied from December 26, 2010, together with the consequential tax effects. These adjustments also reflect the removal of StarBev historical interest expense on debt that was repaid at the time of the Acquisition, the addition of interest expense to be prospectively incurred on the debt issued to finance the Acquisition and the removal of the previously mentioned acquisition-related costs of $31.4 million incurred in the first half of 2012. Additional significant adjustments for 2012 include the removal of the following non-recurring, transaction-related costs included in the historical operating results: a $57.9 million Euro currency loss, a $39.2 million loss related to standard pre-issuance U.S. Treasury interest rate hedges ("Treasury Locks"), and bridge facility costs of $13.0 million, as further described in Note 8, "Other Income and Expense" and Note 14, "Derivative Instruments and Hedging Activities", as well as expense of $8.6 million related to the fair value adjustment to acquisition date inventory that was recorded in the post-acquisition condensed consolidated statements of operations. The adjustments recorded in the first half of 2013 upon finalizing purchase accounting, as further described below, did not result in an adjustment to our previously filed pro forma information. These adjustments do not reflect changes in fair value of the embedded conversion feature or foreign exchange movements of the convertible note issued to the Seller as part of the Acquisition. This unaudited pro forma financial information is not intended to reflect the performance which would have actually resulted had the Acquisition been effected on the dates indicated. Further, the unaudited pro forma results of operations are not necessarily indicative of the results of operations that may be obtained in the future.

Schedule of Assets Acquired And Liabilities Assumed	'
	The following table represents the finalized allocation of the total consideration to the identifiable net assets, fair value of the noncontrolling interest, and resulting residual goodwill as of June 15, 2012. These allocated amounts were updated for immaterial changes in the first half of 2013 and are now finalized. During the second quarter of 2013 we recorded liabilities in several Central European countries primarily related to local country regulatory matters associated with pre-acquisition periods. Some of these items, if materialized, are subject to various claims with the previous owners of the Central Europe business. We also made adjustments to the brand intangible assets, and related deferred tax impacts, as we completed our brand intangible asset valuation in the second quarter of 2013.

	-1	During 2013 and 2012, we recognized expenses associated with restructuring programs focused on labor savings and organizational effectiveness across all functions. As a result, we have reduced headcount by approximately 740 employees since the start of 2012.

	-2	During the third quarter and first three quarters of 2013 and 2012, we recognized charges related to special termination benefits as eligible employees elected early retirement offered as a result of the ratification of collective bargaining agreements with MCC's brewery groups.

	-3	During the second quarter of 2012, we recognized an asset abandonment charge related to the discontinuation of primary packaging in the U.K. We determined that our Home Draft package was not meeting expectations driven by a lack of demand in the U.K. market and as a result, we recognized a loss related to the write-off of the Home Draft packaging line, tooling equipment and packaging materials inventory.

	-4	During the third quarter of 2013, we recognized impairment charges related to indefinite-lived intangible assets in Europe. See Note 11, "Goodwill and Intangible Assets" for further discussion.

	-5	In the second quarter of 2012, we recognized impairment charges related to goodwill and definite-lived intangible assets in our joint venture in China. See Note 11, "Goodwill and Intangible Assets" for further discussion. In the third quarter of 2012, we deconsolidated our MC Si'hai joint venture in China due to a loss of our ability to control the joint venture and recognized an impairment loss of $27.6 million upon deconsolidation and $0.9 million of related costs.

	-6	In the third quarter of 2012, we incurred expenses in excess of insurance proceeds related to flood damage at our Toronto offices. In the first three quarters of 2012, we received insurance proceeds in excess of expenses incurred related to these damages.

	-7	During the third quarter and first three quarters of 2013, we recorded losses and related costs of $2.6 million and $5.9 million, respectively, in our Europe business related to significant flooding in Czech Republic in the second quarter of 2013. These losses were offset by $3.3 million insurance proceeds received in the second quarter of 2013.

	-8	During 2009, we established a non-income-related tax reserve of $10.4 million that was recorded as a special item. The amounts recorded in 2013 and 2012 represent the release of this reserve as a result of a change in estimate. As a result, the remaining amount of this non-income-related tax reserve was fully released in the first quarter of 2013.

	-1	We incurred costs in connection with the issuance and subsequent termination of the bridge loan agreement entered into concurrent with the announcement of the Acquisition during the second quarter of 2012.

	-2	In connection with the Acquisition, we used the proceeds from our issuance of the $1.9 billion senior notes to purchase Euros. As a result of an unfavorable foreign exchange movement between the Euro and USD prior to using these proceeds to fund the Acquisition, we realized a foreign exchange loss on our Euro cash holdings during the second quarter of 2012.

	-3	During the first quarter of 2013, we realized a gain for proceeds received related to a non-income-related tax settlement resulting from historical activity within our former investment in the Montreal Canadiens.

	-4	Included in this amount are losses of $11.4 million and $1.4 million for the third quarter and first three quarters of 2013, respectively, and losses of $6.4 million and $5.8 million for the third quarter and first three quarters of 2012, respectively, related to foreign currency movements on foreign-denominated financing instruments entered into in conjunction with the closing of the Acquisition. We additionally recorded a net gain of $1.8 million and loss of $4.9 million for the third quarter and first three quarters of 2013, respectively, related to foreign cash positions and foreign exchange contracts entered into to hedge our risk associated with the payment of this foreign-denominated debt. See Note 12, "Debt" and Note 14, "Derivative Instruments and Hedging Activities" for further discussion of financing and hedging activities related to the Acquisition. Additionally, we recorded gains of $4.3 million and losses of $5.1 million related to other foreign exchange and derivative activity during the third quarter and first three quarters of 2013, respectively. We recorded losses related to other foreign exchange and derivative activity of $2.9 million for the first three quarters of 2012.

We assigned the majority of the goodwill resulting from the Acquisition to our Europe reporting unit with a portion allocated to the Canada reporting unit resulting from synergies. The allocation of goodwill to our Canada reporting unit was not impacted by the changes made in the first half of 2013 and is now final. See Note 3, "Acquisition of StarBev" for further discussion.

	-1	Our $575 million convertible notes matured and were repaid on July 30, 2013, for their face value of $575 million. The required premium payment of $2.6 million, which was based on our weighted-average Class B common stock price exceeding the then-applicable conversion price on any of the 25 trading days following the maturity date, was paid in September 2013. This premium was hedged by call options that mitigated our exposure to increases in our stock price and resulted in proceeds of $2.6 million from these call options in September 2013, which fully offset the premium payment. Separately, the warrants entered into concurrent with these call options, pursuant to which we may be required to issue Class B common stock to the counterparty when our stock price reaches $66.13 per share, remain outstanding and will expire beginning December 2013 through February 2014. The original conversion price for each $1,000 aggregate principal amount of notes was $54.76 per share of our Class B common stock, which represented a 25% premium above the stock price on the day of issuance of the notes and corresponded to the initial conversion ratio of 18.263 shares per each $1,000 aggregate principal amount of notes. The conversion ratio and conversion price were subject to adjustments for certain events and provisions, as defined in the indenture, including adjustments reflected for exceeding defined thresholds related to our dividend payments. At the maturity date our conversion price and ratio were $51.8284 and 19.2944 shares, respectively.
	During the third quarters of 2013 and 2012, we incurred additional non-cash interest expense of $1.6 million and $4.5 million, respectively. For the first three quarters of 2013 and 2012, the amounts were $10.9 million and $13.5 million, respectively. We also incurred interest expense related to the 2.5% convertible coupon rate of $1.2 million and $3.6 million during the third quarters of 2013 and 2012, respectively. For the first three quarters of 2013 and 2012, the interest expenses incurred were $8.4 million and $10.8 million, respectively. The combination of non-cash and cash interest resulted in an effective interest rate of 5.75% and 5.78% for the third quarters of 2013, through settlement, and 2012, respectively. The effective interest rates for the first three quarters of 2013, through settlement, and 2012 were 5.73% and 5.79%, respectively. As of September 28, 2013, there was no unamortized debt discount outstanding as we recorded the remaining discount of $1.6 million upon maturity in the third quarter of 2013. As of December 29, 2012, $10.8 million of the unamortized debt discount related to our $575 million convertible debt.

	-2	On June 15, 2012, we issued a €500 million Zero Coupon Senior Unsecured Convertible Note due December 31, 2013 (the ''Convertible Note'') to the Seller in conjunction with the closing of the Acquisition. The Seller had the ability to exercise a put right with respect to the Convertible Note as of March 14, 2013, (the “First Redemption Date”) and ending on December 19, 2013, for the greater of the principal amount of the Convertible Note or the aggregate cash value of 12,894,044 shares of our Class B Common Stock, as adjusted for certain corporate events. In accordance with these terms, on August 13, 2013, the Seller exercised the conversion feature for an agreed upon value upon exercise of €510.9 million, consisting of €500 million in principal and €10.9 million for the conversion feature. At issuance, the total value of the Convertible Note was €511.1 million, consisting of the principal (€500 million), discount (€1.0 million), and conversion feature (€12.1 million), initially recorded as a component of the purchase price associated with the Acquisition.
	Separate from the Seller's notice to put, we have made claims with regard to the representations and warranties provided to us upon close of the Acquisition. As a result, we have withheld €44.9 million ($60.8 million as of September 28, 2013) from the €500 million in principal related to these outstanding claims. The remaining balance continues to be classified as current portion of long-term debt pending the resolution of these claims. Therefore, on September 3, 2013, we paid the seller in cash a total of €466.0 million ($614.7 million) consisting of €455.1 million ($600.3 million) in principal and €10.9 million ($14.4 million) for the conversion feature.
	The Convertible Note's embedded conversion feature was determined to meet the definition of a derivative required to be bifurcated and separately accounted for at fair value with changes in fair value recorded in earnings. During the third quarter and first three quarters of 2013, we recognized a net gain of $20.3 million and a loss of $6.5 million, respectively, on the conversion feature primarily related to the change from the previously recorded fair value to the value upon exercise. The Convertible Note was issued at a discount of $1.3 million, which has been recognized as interest expense over the period from issuance to the First Redemption Date. The non-cash interest, excluding the change in fair value of the convertible feature, resulted in an immaterial impact to our effective interest rate for the third quarter and first three quarters of 2013. See Note 14, "Derivative Instruments and Hedging Activities" for further discussion.

	-3	During the third quarter and first three quarters of 2013, we made principal repayments of $71.8 million (€53.7 million) and $123.8 million (€93.7 million), respectively, on the remaining balance of our €120 million term loan. As a result, the term loan, which was designated as a net investment hedge, was fully repaid in the third quarter of 2013. See Note 14, "Derivative Instruments and Hedging Activities" for further discussion.

	-4	In the first quarter of 2013, a $950 million commercial paper program was approved and implemented. The commercial paper program is supported by our $550 million and $400 million revolving credit facilities. To fund the repayment of our €500 million Zero Coupon Senior Unsecured Convertible Note, we issued short-term commercial paper during the third quarter of 2013. As of September 28, 2013, the outstanding borrowings under the commercial paper program were $391.1 million.
	In the third quarter of 2012, we entered into a 1-year, €150 million revolving credit agreement, on an uncommitted basis, to support our operations in Central Europe within our Europe segment. In the third quarter of 2013, this revolving credit facility was renewed and restructured and will continue to provide €150 million on an uncommitted basis through September 2014. As of September 28, 2013, the outstanding borrowings under this revolving credit facility were $162.3 million. There were no outstanding borrowings under this revolving credit facility as of December 29, 2012.
	In the second quarter of 2012, we entered into a 4-year, $550 million revolving credit agreement. This credit agreement contains customary events of default and specified representations and warranties and covenants, including, among other things, covenants that limit our subsidiaries' ability to incur certain additional priority indebtedness, create or permit liens on assets, or engage in mergers or consolidations. As of September 28, 2013, and December 29, 2012, there were no outstanding borrowings under this revolving credit facility.
	In the second quarter of 2011, we entered into an agreement for a 4-year, $400 million revolving multicurrency credit facility, which provides a $100 million sub-facility available for the issuance of letters of credit. As of September 28, 2013 and December 29, 2012, there were no outstanding borrowings under this revolving credit facility.
	The remaining outstanding balances as of September 28, 2013, and December 29, 2012, relate to other short-term borrowings.

	-1	During the first quarter of 2013, we recorded a tax adjustment related to the reclassification of amounts from the investment in MillerCoors to AOCI that was recorded in the fourth quarter of 2012 to reflect our proportional share of MillerCoors AOCI at formation. We made this reclassification in 2012 as we believe the new presentation provides improved transparency of our share of MillerCoors AOCI. This tax adjustment, which should have been made in 2012 with the reclassification, was not material to either the current or prior period financial statements taken as a whole and therefore prior periods do not reflect the adjustment.

	-2	During the third quarter of 2013, we identified that we had incorrectly recorded tax adjustments related to certain foreign currency movements in the financial statements for both the first and second quarters of 2013. See Note 1, "Basis of Presentation and Summary of Significant Accounting Policies" for further discussion.

Our net investment in MillerCoors is based on the carrying values of the net assets contributed to the joint venture which is less than our proportional share of underlying equity (42%) of MillerCoors (contributed by both Coors Brewing Company ("CBC") and Miller Brewing Company ("Miller")). This basis difference, with the exception of certain non-amortizing items (goodwill, land, etc.), is being amortized as additional equity income over the remaining useful lives of the contributed long-lived amortizing assets.

[2]

Results for the three months and nine months ended September 30, 2013, include special charges of $15.0 million related to restructuring activities. Results for the three months and nine months ended September 30, 2012, include special charges of $18.7 million and $16.4 million, respectively, primarily due to the write-down of assets related to discontinuing the production of the Home Draft package in the U.S.

[1]

During 2013 and 2012, we recognized expenses associated with restructuring programs focused on labor savings and organizational effectiveness across all functions. As a result, we have reduced headcount by approximately 740 employees since the start of 2012.

[2]

During the third quarter and first three quarters of 2013 and 2012, we recognized charges related to special termination benefits as eligible employees elected early retirement offered as a result of the ratification of collective bargaining agreements with MCC's brewery groups

[3]

In the third quarter of 2012, we incurred expenses in excess of insurance proceeds related to flood damage at our Toronto offices. In the first three quarters of 2012, we received insurance proceeds in excess of expenses incurred related to these damages.

[4]

During the second quarter of 2012, we recognized an asset abandonment charge related to the discontinuation of primary packaging in the U.K. We determined that our Home Draft package was not meeting expectations driven by a lack of demand in the U.K. market and as a result, we recognized a loss related to the write-off of the Home Draft packaging line, tooling equipment and packaging materials inventory.

[5]

During the third quarter and first three quarters of 2013, we recorded losses and related costs of $2.6 million and $5.9 million, respectively, in our Europe business related to significant flooding in Czech Republic in the second quarter of 2013. These losses were offset by $3.3 million insurance proceeds received in the second quarter of 2013.

[6]

During 2009, we established a non-income-related tax reserve of $10.4 million that was recorded as a special item. The amounts recorded in 2013 and 2012 represent the release of this reserve as a result of a change in estimate. As a result, the remaining amount of this non-income-related tax reserve was fully released in the first quarter of 2013.

[7]

During the third quarter of 2013, we recognized impairment charges related to indefinite-lived intangible assets in Europe. See Note 11, "Goodwill and Intangible Assets" for further discussion.

[8]

In the second quarter of 2012, we recognized impairment charges related to goodwill and definite-lived intangible assets in our joint venture in China. See Note 11, "Goodwill and Intangible Assets" for further discussion. In the third quarter of 2012, we deconsolidated our MC Si'hai joint venture in China due to a loss of our ability to control the joint venture and recognized an impairment loss of $27.6 million upon deconsolidation and $0.9 million of related costs.

[1]

We incurred costs in connection with the issuance and subsequent termination of the bridge loan agreement entered into concurrent with the announcement of the Acquisition during the second quarter of 2012.

[2]

In connection with the Acquisition, we used the proceeds from our issuance of the $1.9 billion senior notes to purchase Euros. As a result of an unfavorable foreign exchange movement between the Euro and USD prior to using these proceeds to fund the Acquisition, we realized a foreign exchange loss on our Euro cash holdings during the second quarter of 2012.

[3]

During the first quarter of 2013, we realized a gain for proceeds received related to a non-income-related tax settlement resulting from historical activity within our former investment in the Montreal Canadiens.

[4]

Included in this amount are losses of $11.4 million and $1.4 million for the third quarter and first three quarters of 2013, respectively, and losses of $6.4 million and $5.8 million for the third quarter and first three quarters of 2012, respectively, related to foreign currency movements on foreign-denominated financing instruments entered into in conjunction with the closing of the Acquisition. We additionally recorded a net gain of $1.8 million and loss of $4.9 million for the third quarter and first three quarters of 2013, respectively, related to foreign cash positions and foreign exchange contracts entered into to hedge our risk associated with the payment of this foreign-denominated debt. See Note 12, "Debt" and Note 14, "Derivative Instruments and Hedging Activities" for further discussion of financing and hedging activities related to the Acquisition. Additionally, we recorded gains of $4.3 million and losses of $5.1 million related to other foreign exchange and derivative activity during the third quarter and first three quarters of 2013, respectively. We recorded losses related to other foreign exchange and derivative activity of $2.9 million for the first three quarters of 2012.

The goodwill resulting from the Acquisition is primarily attributable to Central Europe's licensed brand brewing, distribution and import business, anticipated synergies and the assembled workforce. We assigned the majority of the goodwill to our Europe reporting unit with a portion allocated to the Canada reporting unit resulting from synergies. The goodwill is not deductible for tax purposes. See Note 11, "Goodwill and Intangible Assets" for further discussion.

[2]

During the second quarter of 2013, we finalized purchase accounting related to the Acquisition with a resulting reduction to Europe goodwill in the first half of 2013 of $15.4 million. We assigned the majority of the goodwill resulting from the Acquisition to our Europe reporting unit with a portion allocated to the Canada reporting unit resulting from synergies. The allocation of goodwill to our Canada reporting unit was not impacted by the changes made in the first half of 2013 and is now final. See Note 3, "Acquisition of StarBev" for further discussion.

Our $575 million convertible notes matured and were repaid on July 30, 2013, for their face value of $575 million. The required premium payment of $2.6 million, which was based on our weighted-average Class B common stock price exceeding the then-applicable conversion price on any of the 25 trading days following the maturity date, was paid in September 2013. This premium was hedged by call options that mitigated our exposure to increases in our stock price and resulted in proceeds of $2.6 million from these call options in September 2013, which fully offset the premium payment. Separately, the warrants entered into concurrent with these call options, pursuant to which we may be required to issue Class B common stock to the counterparty when our stock price reaches $66.13 per share, remain outstanding and will expire beginning December 2013 through February 2014. The original conversion price for each $1,000 aggregate principal amount of notes was $54.76 per share of our Class B common stock, which represented a 25% premium above the stock price on the day of issuance of the notes and corresponded to the initial conversion ratio of 18.263 shares per each $1,000 aggregate principal amount of notes. The conversion ratio and conversion price were subject to adjustments for certain events and provisions, as defined in the indenture, including adjustments reflected for exceeding defined thresholds related to our dividend payments. At the maturity date our conversion price and ratio were $51.8284 and 19.2944 shares, respectively. During the third quarters of 2013 and 2012, we incurred additional non-cash interest expense of $1.6 million and $4.5 million, respectively. For the first three quarters of 2013 and 2012, the amounts were $10.9 million and $13.5 million, respectively. We also incurred interest expense related to the 2.5% convertible coupon rate of $1.2 million and $3.6 million during the third quarters of 2013 and 2012, respectively. For the first three quarters of 2013 and 2012, the interest expenses incurred were $8.4 million and $10.8 million, respectively. The combination of non-cash and cash interest resulted in an effective interest rate of 5.75% and 5.78% for the third quarters of 2013, through settlement, and 2012, respectively. The effective interest rates for the first three quarters of 2013, through settlement, and 2012 were 5.73% and 5.79%, respectively. As of SeptemberB 28, 2013, there was no unamortized debt discount outstanding as we recorded the remaining discount of $1.6 million upon maturity in the third quarter of 2013. As of DecemberB 29, 2012, $10.8 million of the unamortized debt discount related to our $575 million convertible debt.

[2]

On June 15, 2012, we issued a €500 million Zero Coupon Senior Unsecured Convertible Note due December 31, 2013 (the ''Convertible Note'') to the Seller in conjunction with the closing of the Acquisition. The Seller had the ability to exercise a put right with respect to the Convertible Note as of March 14, 2013, (the bFirst Redemption Dateb) and ending on December 19, 2013, for the greater of the principal amount of the Convertible Note or the aggregate cash value of 12,894,044 shares of our Class B Common Stock, as adjusted for certain corporate events. In accordance with these terms, on August 13, 2013, the Seller exercised the conversion feature for an agreed upon value upon exercise of €510.9 million, consisting of €500 million in principal and €10.9 million for the conversion feature. At issuance, the total value of the Convertible Note was €511.1 million, consisting of the principal (€500 million), discount (€1.0 million), and conversion feature (€12.1 million), initially recorded as a component of the purchase price associated with the Acquisition.Separate from the Seller's notice to put, we have made claims with regard to the representations and warranties provided to us upon close of the Acquisition. As a result, we have withheld €44.9 million ($60.8 million as of September 28, 2013) from the €500 million in principal related to these outstanding claims. The remaining balance continues to be classified as current portion of long-term debt pending the resolution of these claims. Therefore, on September 3, 2013, we paid the seller in cash a total of €466.0 million ($614.7 million) consisting of €455.1 million ($600.3 million) in principal and €10.9 million ($14.4 million) for the conversion feature. The Convertible Note's embedded conversion feature was determined to meet the definition of a derivative required to be bifurcated and separately accounted for at fair value with changes in fair value recorded in earnings. During the third quarter and first three quarters of 2013, we recognized a net gain of $20.3 million and a loss of $6.5 million, respectively, on the conversion feature primarily related to the change from the previously recorded fair value to the value upon exercise. The Convertible Note was issued at a discount of $1.3 million, which has been recognized as interest expense over the period from issuance to the First Redemption Date. The non-cash interest, excluding the change in fair value of the convertible feature, resulted in an immaterial impact to our effective interest rate for the third quarter and first three quarters of 2013. See Note 14, "Derivative Instruments and Hedging Activities" for further discussion.

[3]

During the third quarter and first three quarters of 2013, we made principal repayments of $71.8 million (€53.7 million) and $123.8 million (€93.7 million), respectively, on the remaining balance of our €120 million term loan. As a result, the term loan, which was designated as a net investment hedge, was fully repaid in the third quarter of 2013. See Note 14, "Derivative Instruments and Hedging Activities" for further discussion.

[4]

In the first quarter of 2013, a $950 million commercial paper program was approved and implemented. The commercial paper program is supported by our $550 million and $400 million revolving credit facilities. To fund the repayment of our €500 million Zero Coupon Senior Unsecured Convertible Note, we issued short-term commercial paper during the third quarter of 2013. As of SeptemberB 28, 2013, the outstanding borrowings under the commercial paper program were $391.1 million.In the third quarter of 2012, we entered into a 1-year, €150 million revolving credit agreement, on an uncommitted basis, to support our operations in Central Europe within our Europe segment. In the third quarter of 2013, this revolving credit facility was renewed and restructured and will continue to provide €150 million on an uncommitted basis through September 2014. As of SeptemberB 28, 2013, the outstanding borrowings under this revolving credit facility were $162.3 million. There were no outstanding borrowings under this revolving credit facility as of DecemberB 29, 2012.In the second quarter of 2012, we entered into a 4-year, $550 million revolving credit agreement. This credit agreement contains customary events of default and specified representations and warranties and covenants, including, among other things, covenants that limit our subsidiaries' ability to incur certain additional priority indebtedness, create or permit liens on assets, or engage in mergers or consolidations. As of SeptemberB 28, 2013, and DecemberB 29, 2012, there were no outstanding borrowings under this revolving credit facility. In the second quarter of 2011, we entered into an agreement for a 4-year, $400 million revolving multicurrency credit facility, which provides a $100 million sub-facility available for the issuance of letters of credit. As of SeptemberB 28, 2013 and DecemberB 29, 2012, there were no outstanding borrowings under this revolving credit facility. The remaining outstanding balances as of SeptemberB 28, 2013, and DecemberB 29, 2012, relate to other short-term borrowings.
