Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

The Company has identified the significant accounting policies that are critical to understanding its business and results of operations.

Leases

The Company adopted ASU No. 2016-02, "Leases" ("ASU 2016-02") on January 1, 2019 using the modified retrospective approach. The Company also elected the package of practical expedients, which among other things, allowed the Company to carryforward historical lease classification. The adoption of the standard resulted in (1) the derecognition of building assets and finance lease obligations for certain leases that did not pass the sale-leaseback criteria, (2) the derecognition of construction in progress assets and other long-term liabilities for certain lease arrangements whereby the Company is no longer considered the deemed construction owner of the construction projects, and (3) the recognition of operating lease right-of-use ("ROU") assets and lease liabilities for lease arrangements with an initial term greater than twelve months.

Adoption of ASU 2016-02 resulted in the following adjustments to the balance sheet (in thousands):

	December 31, 2018			ASU 2016-02 Adjustments			January 1, 2019
Balance sheet line item
Property and equipment, net	$	606,977		$	(227,709	)	$	379,268
Operating lease right-of-use assets	$	—		$	524,082		$	524,082
Other noncurrent assets	$	18,826		$	(6,814	)	$	12,012
Other liabilities	$	160,388		$	(155,996	)	$	4,392
Other current liabilities	$	127,995		$	(9,624	)	$	118,371
Lease financing obligation, net of current portion	$	183,056		$	(183,056	)	$	—
Operating lease liabilities	$	—		$	636,385		$	636,385
Accumulated deficit	$	(1,082,689	)	$	1,850		$	(1,080,839	)

The adoption of the standard did not have a notable impact on the Company's liquidity or a materially adverse impact on the Company's debt covenant compliance.

The Company determines if an arrangement is a lease at inception. Operating leases are included in "Operating lease right-of-use assets," "Other current liabilities," and "Operating lease liabilities" on our consolidated and condensed balance sheets. As of September 30, 2019, the Company has not entered into material financing lease arrangements.

Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that management will exercise that option. The Company has lease arrangements with lease and non-lease components. For the Company's warehouse and fulfillment center lease arrangements, the Company accounts for lease and non-lease components separately. For all other lease arrangements, the Company accounts for lease and non-lease components as a single lease component.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company's leases do not provide an implicit rate, the Company uses its estimated incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The determination of the Company’s incremental borrowing rate requires judgment. The incremental borrowing rate for each lease is primarily based on publicly-available information for companies within the same industry and with similar credit profiles. The rate is then adjusted for the impact of collateralization, the lease term and other specific terms included in the Company’s lease arrangements. The incremental borrowing rate was determined at lease commencement, or as of January 1, 2019 for operating leases existing upon adoption of ASC 842. The incremental borrowing rate is subsequently reassessed upon a modification to the lease arrangement. The operating lease ROU asset also includes any lease payments made prior to commencement date and excludes lease incentives and initial direct costs incurred. ROU assets are subsequently assessed for impairment in accordance with the Company’s accounting policy for long-lived assets.

Stock Compensation

The Company adopted ASU No. 2018-07, Compensation – Stock Compensation (Topic 718), Improvements to Nonemployee Share-Based Payment Accounting ("ASU 2018-07") on January 1, 2019. The ASU simplifies aspects of share-based compensation issued to non-employees by making the guidance consistent with the accounting for employee share-based compensation. The adoption of ASU 2018-07 did not have a material impact the Company’s consolidated financial position, results of operations, comprehensive loss, stockholders' deficit or cash flows.

Hosting Arrangements

In August 2018, the FASB issued guidance related to a customer’s accounting for implementation costs incurred in hosting arrangements. The guidance aligns the requirements for capitalizing implementation costs incurred in cloud computing arrangements with the requirements for capitalizing costs to develop or obtain internal-use software. This guidance is effective for interim and annual reporting periods beginning after December 15, 2019, and early adoption is permitted. This guidance may be applied either retrospectively or prospectively. The Company early adopted the guidance on a prospective basis as of January 1, 2019. The adoption of the guidance did not have a material impact on the Company's consolidated financial position, results of operations, comprehensive loss, stockholders' deficit or cash flows.

The Company believes that other than the implementation of ASU 2016-02 and ASU 2018-07, there have been no significant changes during the nine months ended September 30, 2019 to the items disclosed in Note 2, Summary of Significant Accounting Policies, included in Part II, Item 8, Financial Statements and Supplementary Data, of the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.
