Table of Contents 20. Quarterly Financial Information (Unaudited) Correction of Previously Issued Unaudited Condensed Consolidated Financial Statements for Income Tax Accounting Errors The 2017 quarterly information reflects retrospective adjustments for the adoption of the new accounting guidance related to defined benefit pension and other postretirement plans as discussed in  Note 2, "New Accounting Pronouncements." The sum of the quarterly net income per share amounts may not agree to the full-year net income per share amounts. We calculate net income per share based on the weighted-average number of outstanding shares during the reporting period. The average number of shares fluctuates throughout the year and can therefore produce a full-year result that does not agree to the sum of the individual quarters. As a result of the corrections of the income tax accounting errors discussed in  Note 1, "Basis of Presentation and Summary of Significant Accounting Policies,"  we have corrected our previously disclosed unaudited condensed consolidated statements of operations for the three month and year-to-date periods ended June 30, 2017, September 30, 2017, and December 31, 2017, and the unaudited condensed consolidated balance sheets as of the end of each of the quarterly periods in 2017 and 2018. Specifically, in addition to the impacts of the errors described in  Note 1, "Basis of Presentation and Summary of Significant Accounting Policies,"  we have further corrected our 2017 unaudited interim financial statements to increase the deferred tax liability and corresponding deferred tax expense by $2.9 million for the three months ended June 30, 2017, and to decrease the deferred tax liability and corresponding deferred tax expense by $26.2 million and $128.1 million for the three months ended September 30, 2017, and December 31, 2017, respectively. There was no impact of the corrections on the unaudited condensed consolidated statements of operations for the three months ended March 31, 2017, or for the three months and year-to-date periods ended March 31, 2018, June 30, 2018, and September 30, 2018. We assessed the applicable guidance issued by the SEC and the FASB and concluded that these errors in the 2017 and 2018 quarterly and year-to-date financial statements were not material, individually or in the aggregate, to MCBC’s previously issued unaudited interim condensed consolidated financial statements for the applicable interim periods included in our Quarterly Reports on Form 10-Q for the aforementioned quarterly periods. The errors in the three months ended December 31, 2017, were material and as such are described as restated. The revision of our previously issued unaudited condensed consolidated financial statements for the three months ended March 31, 2018, three and six months ended June 30, 2018, and the three and nine months ended September 30, 2018, will be affected in connection with our quarterly filings for the quarters ending March 31, June 30, and September 30, 2019, respectively. 171 First Quarter Second Quarter Third Quarter Fourth Quarter 2018 2017 2018 2017 As Revised 2018 2017 As Revised 2018 2017 As Restated (In millions, except per share data) Sales $ 2,868.0 $ 2,913.8 $ 3,820.5 $ 3,793.1 $ 3,625.1 $ 3,552.9 $ 3,024.4 $ 3,211.7 Excise taxes (536.5) (465.1) (735.3) (701.8) (690.9) (669.7) (605.7) (632.1) Net sales 2,331.5 2,448.7 3,085.2 3,091.3 2,934.2 2,883.2 2,418.7 2,579.6 Cost of goods sold (1,535.7) (1,372.3) (1,739.1) (1,755.5) (1,714.0) (1,589.1) (1,596.0) (1,519.8) Gross profit $ 795.8 $ 1,076.4 $ 1,346.1 $ 1,335.8 $ 1,220.2 $ 1,294.1 $ 822.7 $ 1,059.8 Amounts attributable to Molson Coors Brewing Company: Net income (loss) attributable to Molson Coors Brewing Company $ 278.1 $ 208.5 $ 424.1 $ 327.0 $ 338.3 $ 313.2 $ 76.0 $ 716.9 Basic net income (loss) attributable to Molson Coors Brewing Company per share $ 1.29 $ 0.97 $ 1.96 $ 1.52 $ 1.57 $ 1.45 $ 0.35 $ 3.33 Diluted net income (loss) attributable to Molson Coors Brewing Company per share $ 1.28 $ 0.96 $ 1.96 $ 1.51 $ 1.56 $ 1.45 $ 0.35 $ 3.31
