Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated balance sheet as of June 30, 2013, the unaudited condensed consolidated statements of operations and comprehensive income for the three and six months ended June 30, 2013 and 2012, and the unaudited condensed consolidated statements of cash flows for the six months ended June 30, 2013 and 2012 have been prepared on the same basis as our audited consolidated financial statements and include all adjustments necessary for the fair presentation of our consolidated results of operations, financial position, comprehensive income 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. The condensed consolidated balance sheet as of December 31, 2012 has been derived from our audited financial statements, which are included in our 2012 Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 14, 2013. The significant accounting policies and certain financial information that are normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States ("GAAP"), but which are not required for interim reporting purposes, have been omitted. The unaudited condensed consolidated interim financial statements should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2012. Concentration of Credit Risks Financial instruments, which potentially subject us to concentrations of credit risk, consist principally of cash investments, accounts receivable and other receivables. We place our cash and cash equivalents in short-term instruments with high quality financial institutions and limit the amount of credit exposure in any one financial instrument. The Company's policy is to perform credit reviews for new customers and conduct ongoing credit evaluations of each customer's financial condition. We assign credit limits to customers based on a risk assessment of their ability to pay and other factors. In addition, prepayments and other guarantees are required whenever deemed necessary. Alimentation Couche-Tard, Inc. (“Couche-Tard”) accounted for approximately 13% of our net sales in both the three and six months ended June 30, 2013 and for the same periods in 2012.
