Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated balance sheet as of March 31, 2013 and the unaudited condensed consolidated statements of operations, comprehensive income and cash flows for the three months ended March 31, 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 accounting principles generally accepted in the United States, 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. A credit review is completed for new customers and ongoing credit evaluations of each customer's financial condition are performed and prepayment or other guarantees are required whenever deemed necessary. Credit limits given to customers are based on a risk assessment of their ability to pay and other factors. Alimentation Couche-Tard, Inc. (“Couche-Tard”) accounted for approximately 13.4% and 13.5% of our net sales in the first quarter of 2013 and 2012, respectively. No single customer accounted for 10% or more of our accounts receivables as of March 31, 2013 or December 31, 2012. Recent Accounting Pronouncements In February 2013, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date. This ASU provides 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, except for obligations addressed within existing guidance under U.S. generally accepted accounting principles (“GAAP”). Examples of obligations within the scope of this ASU include debt arrangements, settled litigation and judicial rulings and other contractual obligations. This guidance is effective for interim and annual periods beginning on January 1, 2014 and must be retroactively applied to prior periods presented. Management is currently assessing the impact of this guidance to the Company’s financial position and results of operations and does not expect this ASU to have a material effect on our consolidated financial statements. In February 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. ASU 2013-02 requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under GAAP to be reclassified in its entirety to net income. For other amounts that are not required under GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. GAAP that provide additional detail about those amounts. The Company adopted this ASU beginning January 1, 2013 and it did not have a material effect on our consolidated financial statements.
