Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated balance sheets as of June 30, 2019 , the unaudited condensed consolidated statements of operations and comprehensive income, the unaudited condensed consolidated statements of stockholders equity for the three and six months ended June 30, 2019 and 2018 , and the unaudited condensed consolidated statements of cash flows for the six months ended June 30, 2019 and 2018 , have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission (SEC) for interim reporting. Accordingly, certain footnotes and other financial information that are normally required by generally accepted accounting principles in the U.S. (GAAP) have been condensed or omitted. The condensed consolidated balance sheet as of December 31, 2018 has been derived from the Companys audited financial statements, which are included in its 2018 Annual Report on Form 10-K, filed with the SEC on March 1, 2019 . The consolidated financial statements include Core-Mark and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in the consolidated financial statements. The unaudited condensed consolidated interim financial statements should be read in conjunction with the Companys audited consolidated financial statements in its Annual Report on Form 10-K, for the year ended December 31, 2018 . The unaudited condensed consolidated interim financial statements include all adjustments necessary for the fair presentation of the Companys consolidated results of operations, financial position, comprehensive income, changes in stockholders equity and cash flows. Results for the interim periods are not necessarily indicative of results to be expected for the full year or any other future periods. Subsequent to the issuance of the Companys interim condensed consolidated financial statements as of and for the three and six months ended June 30, 2018 , management determined that the amount of foreign currency translation loss disclosed for the six months ended June 30, 2018 was overstated by $0.9 million in the condensed consolidated statement of comprehensive income, which also impacted retained earnings and accumulated other comprehensive loss by the same amount as of June 30, 2018 , as currently presented in the condensed consolidated statement of stockholders equity. The impacted financial statement line items have been adjusted in the prior periods presented to correct for this overstatement.
