Note 1—Summary of Significant Accounting Policies

U.S. Auto Parts Network, Inc. (collectively with its subsidiaries, the "Company") is a distributor of aftermarket auto parts and accessories and was established in 1995. The Company entered the e-commerce sector by launching its first website in 2000 and currently derives the majority of its revenues from online sales channels. The Company sells its products to individual consumers through a network of websites and online marketplaces. Our flagship websites are located at www.autopartswarehouse.com, www.partstrain.com, www.jcwhitney.com, www.stylintrucks.com and our corporate website is located at www.usautoparts.net.

The Company's products consist of body parts, engine parts, performance parts and accessories. The body parts category is primarily comprised of parts for the exterior of an automobile. Our parts in this category are typically replacement parts for original body parts that have been damaged as a result of a collision or through general wear and tear. In addition, we sell an extensive line of mirror products, including our own private-label brand called Kool-Vue™, which are marketed and sold as aftermarket replacement parts and as upgrades to existing parts. The engine parts category is comprised of engine components and other mechanical and electrical parts, which are often referred to as hard parts. These parts serve as replacement parts for existing engine parts and are generally used by professionals and do-it-yourselfers for engine and mechanical maintenance and repair. We offer performance versions of many parts sold in each of the above categories. Performance parts and accessories generally consist of parts that enhance the performance of the automobile, upgrade existing functionality of a specific part or improve the physical appearance or comfort of the automobile.

The Company is a Delaware C corporation and is headquartered in Carson, California. The Company also has employees located in, Kansas, Virginia, Illinois and Ohio, as well as in the Philippines.

Basis of Presentation

The unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information and with the instructions to U.S. Securities and Exchange Commission ("SEC") Form 10-Q and Article 10 of SEC Regulation S-X. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting of normal recurring adjustments, necessary to present fairly the consolidated financial position of the Company as of July 2, 2011 and January 1, 2011, and the consolidated results of operations for the thirteen and twenty-six weeks ended July 2, 2011 and July 3, 2010, and cash flows for the twenty-six weeks ended July 2, 2011 and July 3, 2010. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. The Company's results of operations for the thirteen and twenty-six weeks ended July 2, 2011 are not necessarily indicative of those to be expected for the entire year. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended January 1, 2011 ("fiscal 2010"), which was filed with the SEC on March 17, 2011.

Principles of Consolidation

The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany balances and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates made by management include, but are not limited to, the valuation of investments, valuation of inventory, valuation of deferred tax assets and liabilities, and valuation of intangible assets, including goodwill. Actual results could differ from these estimates.

Segment Data

The Company manages its operations on a consolidated basis for purposes of assessing performance and making operating decisions. Accordingly, the Company operates in one reportable segment and reporting revenues by product line or geographic location is impracticable.

Recent Accounting Pronouncements

In December 2010, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2010-29, Disclosure of Supplementary Pro Forma Information for Business Combinations ("ASU 2010-29"), an update to Accounting Standards Codification ("ASC") Topic 805, Business Combinations ("ASC 805"). The amendments in ASU 2010-29 specify that if a public entity presents comparative financial statements, the entity should disclose revenue and earnings of the combined entity as though the business combination(s) that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period only. The amendments in ASU 2010-29 also expand the supplemental pro forma disclosures under ASC 805 to include a description of the nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination included in the reported pro forma revenue and earnings. The amendments are effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010. Early adoption is permitted. The Company will apply the provisions of ASU 2010-29 to future acquisitions which occur after January 2, 2011. The Company believes that the adoption will not have a material effect on the Company's consolidated financial statements.

In May 2011, the FASB issued ASU No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs ("ASU 2011-04"), an update to ASC Topic 820, Fair Value Measurement ("ASC 820"). The amendments in ASU 2011-04 are the result of joint efforts by the FASB and International Accounting Standards Board ("IASB") to develop a single, converged fair value framework and provide converged guidance on how to measure fair value and on what disclosures to provide about fair value measurements. While ASU 2011-04 is largely consistent with existing fair value measurement principles in U.S. GAAP, it expands ASC 820's existing disclosure requirements for fair value measurements and makes other amendments. Many of these amendments were made to eliminate unnecessary wording differences between U.S. GAAP and International Financial Reporting Standards ("IFRSs"). However, some could change how the fair value measurement guidance in ASC 820 is applied. For public entities, amendments are effective for interim and annual periods beginning after December 15, 2011. The Company will adopt the provisions of ASU 2011-04 on January 1, 2012, the starting date of its fiscal year ending December 29, 2012. The Company believes that this adoption will not have a material effect on the Company's consolidated financial statements.

In June 2011, the FASB issued ASU No. 2011-05, Presentation of Comprehensive Income ("ASU 2011-05"), an update to ASC Topic 220, Comprehensive Income ("ASC 220"). The amendments in ASU 2011-05 revise the manner in which entities present comprehensive income in their financial statements by removing the presentation options in ASC 220 and requiring entities to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. In both options, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. The amendments in ASU 2011-5 do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. For public entities, the amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. Early adoption is permitted. The Company will adopt the provisions of ASU 2011-05 on January 1, 2012, the starting date of its fiscal year ending December 29, 2012. This adoption will have an impact on the presentation of other comprehensive income on the Company's consolidated financial statements.
