Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The unaudited interim Consolidated Financial Statements have been prepared on the same basis as the audited Consolidated Financial Statements and in the opinion of management, reflect all adjustments, consisting of only normal recurring adjustments, necessary for the fair statement of the Company’s financial position as of September 30, 2017 and December 31, 2016, results of operations for the three months and nine months ended September 30, 2017 and 2016, and cash flows for the nine months ended September 30, 2017 and 2016. These unaudited Consolidated Financial Statements should be read in conjunction with the Company’s audited Consolidated Financial Statements and the notes thereto for the year ended December 31, 2016 included in the Company’s final prospectus related to the IPO, filed with the SEC pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended, on June 29, 2017 (the “Prospectus”). There have been no material changes in the Company's significant accounting policies from those that were disclosed in the Prospectus. The accompanying Consolidated Financial Statements include the accounts of Blue Apron Holdings, Inc. and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The Company prepares its Consolidated Financial Statements and related disclosures in conformity with accounting principles generally accepted in the United States (“GAAP”). Use of Estimates In preparing its Consolidated Financial Statements in accordance with GAAP, the Company is required to make estimates and assumptions that affect the amounts of assets, liabilities, revenue, costs, and expenses, and disclosure of contingent assets and liabilities which are reported in the Consolidated Financial Statements and accompanying disclosures. The accounting estimates that require the most difficult and subjective judgments include revenue recognition, inventory valuation, leases, recoverability of long-lived assets, the fair value of share-based awards, recoverability of net deferred tax assets and related valuation allowance, and the recognition and measurement of income tax uncertainties and other contingencies. The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could materially differ from the Company’s estimates and assumptions. Emerging Growth Company Status The Company is an "emerging growth company," as defined in the Jumpstart Our Business Startups (JOBS) Act, and may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not "emerging growth companies." The Company may take advantage of these exemptions until the Company is no longer an "emerging growth company." Section 107 of the JOBS Act provides that an "emerging growth company" can take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards. The Company has elected to use the extended transition period for complying with new or revised accounting standards and as a result of this election, its financial statements may not be comparable to companies that comply with public company effective dates. The Company may take advantage of these exemptions up until the last day of the fiscal year following the fifth anniversary of the IPO or such earlier time that it is no longer an emerging growth company. The Company would cease to be an emerging growth company if it has more than $1.07 billion in annual revenue, has more than $700.0 million in market value of its stock held by non-affiliates (and it has been a public company for at least 12 months, and has filed one annual report on Form 10-K), or it issues more than $1.0 billion of non-convertible debt securities over a three-year period. Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers (Topic 606). ASU 2014-09 affects any entity that enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. The new guidance will supersede the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. The new standard also includes enhanced disclosures which are significantly more comprehensive than those in existing revenue standards. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Principal versus Agent Considerations), to clarify the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Identifying Performance Obligations and Licensing), to clarify the implementation guidance on identifying performance obligations and licensing. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Narrow-Scope Improvements and Practical Expedients), to clarify the implementation guidance on assessing collectibility, presentation of sales taxes, noncash consideration and completed contracts, and contract modifications at transition. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, (Revenue from Contracts with Customers), to clarify the guidance or to correct unintended application of guidance. In September 2017, the FASB issued ASU No. 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842): Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments, to add SEC paragraphs pursuant to an SEC Staff Announcement made at the July 20, 2017 Emerging Issues Task Force (EITF) meeting. For the Company, the guidance is effective for annual periods beginning after December 15, 2018. Non-public entities are permitted to adopt the standard as early as annual reporting periods beginning after December 15, 2016 and interim periods therein. The Company is evaluating the impact this new guidance may have on its Consolidated Financial Statements. In February 2016, the FASB issued its final standard on lease accounting, Accounting Standards Update No. 2016-02, Leases (Topic 842), which supersedes Topic 840, Leases. The new accounting standard requires the recognition of right-of-use assets and lease liabilities for all long-term leases, including operating leases, on the balance sheet. The new standard also provides additional guidance on the measurement of the right-of-use assets and lease liabilities and will require enhanced disclosures about the Company’s leasing arrangements. In September 2017, the FASB issued ASU No. 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842): Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments, to add SEC paragraphs pursuant to an SEC Staff Announcement made at the July 20, 2017 Emerging Issues Task Force (EITF) meeting. For the Company, the new standard is effective for annual periods beginning after December 15, 2019, with early adoption permitted. The Company is evaluating the impact this new guidance may have on its Consolidated Financial Statements. In March 2016, the FASB issued Accounting Standards Update No. 2016-09 (“ASU 2016-09”), Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Some of the areas of simplification apply only to non-public entities. For the Company, the amendments in ASU 2016-09 are effective for annual periods beginning after December 15, 2017, with early adoption permitted. The Company is evaluating the impact this new guidance may have on its Consolidated Financial Statements. In November 2016, the FASB issued Accounting Standards Update No. 2016-18 (“ASU 2016-18”), Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force). The standard is intended to eliminate diversity in practice in the treatment of restricted cash in the statement of cash flows and requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. For the Company, the amendments in ASU 2016-18 are effective for annual periods beginning after December 15, 2018, with early adoption permitted. The adoption of this guidance is not expected to have a material impact on the Company’s Consolidated Financial Statements. In May 2017, the FASB issued Accounting Standards Update No. 2017-09 (“ASU 2017-09”), Compensation–Stock Compensation (Topic 718): Scope of Modification Accounting. The standard is intended to provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. For the Company, the amendments in ASU 2017-09 are effective for annual periods beginning after December 15, 2017, with early adoption permitted. The Company is evaluating the impact this new guidance may have on its Consolidated Financial Statements.
