Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated balance sheet as of September 30, 2013, the unaudited condensed consolidated statements of operations and the unaudited condensed consolidated statements of comprehensive income for the three and nine months ended September 30, 2013 and 2012, and the unaudited condensed consolidated statements of cash flows for the nine months ended September 30, 2013 and 2012 have been prepared on the same basis as the Company's 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 the Company's audited financial statements, which are included in its 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 the Company's audited consolidated financial statements for the year ended December 31, 2012. Recent Accounting Pronouncements On July 18, 2013, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which requires an entity to present an unrecognized tax benefit as a reduction of a deferred tax asset for a net operating loss (NOL) carryforward, or similar tax loss or tax credit carryforward, rather than as a liability when (1) the uncertain tax position would reduce the NOL or other carryforward under the tax law of the applicable jurisdiction and (2) the entity intends to use the deferred tax asset for that purpose. This accounting standard update will be effective for the Company beginning in the first quarter of 2014 and applied prospectively with early adoption permitted. The Company does not believe that its adoption of this accounting standard will have a material impact on its consolidated financial statements. Concentration of Credit Risks Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash investments, accounts receivable and other receivables. The Company places its cash and cash equivalents in short-term instruments with high quality financial institutions and limits 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. The Company assigns 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 14.7% and 14.8% of the Company's net sales in the three and nine months ended September 30, 2013, respectively, and accounted for approximately 13.7% and 13.6% of the Company's net sales in the three and nine months ended September 30, 2012, respectively. As of September 30, 2013 and December 31, 2012, no single customer accounted for 10% or more of the Company's accounts receivable.
