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 presentation of the Company’s financial position as of March 31, 2019 and December 31, 2018, results of operations for the three months ended March 31, 2019 and 2018, and cash flows for the three months ended March 31, 2019 and 2018 . 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, 2018 included in the Company’s Annual Report on Form 10-K filed with the SEC on February 25, 2019 (the “Annual Report”). The Company adopted Accounting Standards Update No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers (Topic 606) as of January 1, 2019 using a modified retrospective approach. See Revenue Recognition below for further discussion. There have been no other significant changes in the Company's significant accounting policies from those that were disclosed in Note 2, Summary of Significant Accounting Policies, included in the Annual Report. 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”). Revenue Recognition The Company adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606) , as of January 1, 2019. The Company primarily generates revenue from the sale of its products to customers, including meals, wine and kitchen tools. For the three months ended March 31, 2019 and 2018, the Company derived substantially all of its Net revenue from sales of its meals. The Company's revenue contracts represent a single performance obligation to sell its products to its customers. The Company recognizes revenue upon transfer of control, including passage of title to the customer and transfer of risk of loss related to the products, in an amount that reflects the consideration the Company expects to be entitled to. In general, the Company charges credit cards in advance of shipment. Transfer of control generally passes upon delivery to the customer. Sales taxes imposed on the Company’s sales are presented on a net basis in the Consolidated Statements of Operations, and therefore do not impact Net revenue or Cost of goods sold, excluding depreciation and amortization. The Company deducts promotional discounts, actual customer credits and refunds as well as credits and refunds expected to be issued to determine Net revenue. Customers who receive a damaged meal or wine order or are dissatisfied with an order and contact the Company within seven days of receipt of the order may receive a full or partial refund, full or partial credit against future purchase, or replacement, at the Company's sole discretion. Credits only remain available for customers who maintain a valid account with the Company. Customers who return an unused, undamaged Blue Apron Market product within 30 days of receipt receive a full refund. The Company estimates and records expected credits and refunds based on prior history, recent trends, and projections for credits and refunds on sales in the current period . Reserves for credits and refunds are included within Accrued expenses and other current liabilities on the Consolidated Balance Sheet. The Company periodically enters into agreements with third parties to market the Company’s products. The Company records revenue from such arrangements at the gross amount as the Company is the principal in these arrangements as it is primarily responsible for fulfilling the goods to customers, provides primary customer service for such products sold on its website, has latitude in establishing price and selecting such products sold on its website, and maintains inventory risk. The Company has two types of contractual liabilities: (i) cash collections from its customers prior to delivery of products purchased, which are included in Deferred revenue on the Consolidated Balance Sheet, and are recognized as revenue upon transfer of control of its products, and (ii) unredeemed gift cards and other prepaid orders, which are included in Deferred revenue on the Consolidated Balance Sheet, and are recognized as revenue when gift cards are redeemed and the products are delivered. Certain gift cards are not expected to be redeemed, also known as breakage, and are recognized as revenue over the expected redemption period, subject to requirements to remit balances to governmental agencies. Contractual liabilities included in Deferred revenue on the Consolidated Balance Sheets were $10.3 million as of March 31, 2019 and $12.4 million as of December 31, 2018, respectively. During the three months ended March 31, 2019, the Company recognized $10.2 million to Net revenue from the Deferred revenue at December 31, 2018. The Company adopted ASU 2014-09 using a modified retrospective approach and recognized $0.3 million cumulative-effect adjustment to reduce Accumulated deficit as of January 1, 2019. The cumulative-effect adjustment to Accumulated deficit was due to breakage of gift cards to the extent there is no requirement for remitting balances to governmental agencies. Under the modified retrospective approach, prior period balances are not retrospectively adjusted. 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 February 2016, the Financial Accounting Standards Board (“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.

In January 2019, the FASB issued ASU No. 2019-01, Leases (Topic 842): Codification Improvements , to improve and clarify aspects of ASU No. 2016-02. 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 will 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 August 2018, the FASB issued Accounting Standards Update No. 2018-15 (“ASU 2018-15”), Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The standard is intended to clarify the accounting for implementation costs of a hosting arrangement that is a service contract. For the Company, the amendments in ASU 2018-15 are effective for annual periods beginning after December 15, 2020, with early adoption permitted. The Company is evaluating the impact this new guidance may have on its Consolidated Financial Statements. Recently Adopted Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update No. 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 supersedes 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, R evenue from Contracts with Customers (Principal versus Agent Considerations) , to clarify the implementation guidance on principal versus agent considerations.
