The preparation of financial statements in conformity with generally accepted accounting principles requires estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosures of contingent liabilities in our consolidated financial statements and accompanying notes. Estimates are used for, but not limited to, receivables valuation, revenue recognition, Club O and gift card breakage, sales returns, vendor incentive discount offers, inventory valuation, depreciable lives and valuation of property and equipment, and internally-developed software, goodwill valuation, intangible asset valuation, equity securities valuation, income taxes, stock-based compensation, performance-based compensation, self-funded health insurance liabilities, and contingencies.

Our estimates involving, among other items, forecasted revenues, sales volume, pricing, cost and availability of inventory, consumer demand and spending habits, the continued operations of our supply chain and logistics network, changes in interest rates, and the overall impact of social distancing on our workforce are even more difficult to estimate as a result of uncertainties associated with the scope and duration of the global novel coronavirus ("COVID-19") pandemic and various actions taken by governmental authorities, private business and other third parties in response to the pandemic, the ultimate geographic spread of the virus, the ongoing economic effect of the pandemic and the post-pandemic economic recovery. Although these estimates are based on our best knowledge of current events and actions that we may undertake in the future, the variability of these factors depends on a number of conditions, including uncertainty associated with the COVID-19 pandemic, how long these conditions will persist, ongoing developments related to the production, approval and distribution of vaccines, what additional measures may be introduced or reintroduced by governments or private parties or what effect any such additional measures may have on our business and thus our accounting estimates may change from period to period. To the extent there are differences between these estimates and actual results, our consolidated financial statements may be materially affected.

We account for our assets and liabilities using a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. These two types of inputs have created the fair-value hierarchy below. This hierarchy requires us to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value.

Our assets and liabilities that are adjusted to fair value on a recurring basis are cash equivalents, certain equity securities, and deferred compensation liabilities, which fair values are determined using quoted market prices from daily exchange traded markets on the closing price as of the balance sheet date and are classified as Level 1. Our other financial instruments, including cash, restricted cash, accounts receivable, accounts payable, accrued liabilities, finance obligations, and debt are carried at cost, which approximates their fair value. Certain assets, including long-lived assets, certain equity securities, goodwill, cryptocurrencies, and other intangible assets, are measured at fair value on a nonrecurring basis; that is, the assets are not measured at fair value on an ongoing basis, but are subject to fair value adjustments using fair value measurements with unobservable inputs (level 3), apart from cryptocurrencies which use quoted prices from various digital currency exchanges with active markets in certain circumstances (e.g., when there is evidence of impairment).

Accounts receivable consist primarily of trade amounts due from customers in the United States and uncleared credit card transactions at period end. Accounts receivable are recorded at invoiced amounts and do not bear interest. We maintain an allowance for expected credit losses based upon our business customers' financial condition and payment history, our historical collection experience, and any future expected economic conditions.

Inventories include merchandise acquired for resale and processed returns which are accounted for using a standard costing system which approximates the first-in-first-out ("FIFO") method of accounting and are valued at the lower of cost and net realizable value. Inventory valuation requires us to make judgments, based on currently available information, about the likely method of disposition, such as through sales to individual customers, returns to product vendors, liquidations, and expected recoverable values of each disposition category.

Included in property and equipment is the capitalized cost of internal-use software and website development, including software used to upgrade and enhance our Website and processes supporting our business. We capitalize costs incurred during the application development stage of internal-use software and amortize these costs over the estimated useful life. Costs incurred related to design or maintenance of internal-use software are expensed as incurred.

We measured our retained noncontrolling interest in former subsidiaries at fair value at the date of deconsolidation. In the absence of quoted market prices (e.g., a privately held entity), the fair value was determined in good faith under our valuation policy and process using generally accepted valuation approaches. We utilized an independent third party valuation firm to assist us in determining the fair values of our retained noncontrolling interest in former subsidiaries using a combination of a market approach and income approach. The market approach relied upon a comparison with guideline public companies or guideline transactions and entails selecting relevant financial information of the subject company, and capitalizing those amounts using valuation multiples that are based on empirical market observations. The income approach relied upon an analysis of its projected economic earnings discounted to present value (discounted cash flows). The fair value determination of our retained noncontrolling interest required the use of significant unobservable inputs (Level 3 inputs) as shown in the table within Note 4—Discontinued Operations. Due to the inherent uncertainty of determining the fair value of Level 3 securities that do not have a readily available market value, the determination of fair value required significant judgment or estimation and changes in the estimates and assumptions used in the valuation models could materially affect the determination of fair value for these assets. See Note 4—Discontinued Operations for further information.

At December 31, 2021, we held minority interests (less than 20%) in certain public entities, accounted for under ASC Topic 321, Investments—Equity Securities ("ASC 321"), which are included in Equity securities at fair value in our consolidated balance sheets. We measure our ASC 321 equity securities at fair value with changes in fair value recorded in Other income (expense), net in our consolidated statements of operations. Dividends received are reported in earnings if and when received.

At December 31, 2021, we held minority interests in privately held entities, Medici Ventures, L.P. and tZERO, accounted for under the equity method under ASC Topic 323, Investments—Equity Method and Joint Ventures ("ASC 323"), which are included in Equity securities in our consolidated balance sheets. We can exercise significant influence, but not control, over these entities through holding more than a 20% voting interest.

Based on the nature of our ownership interests and the extent of our contributed capital, we held a variable interest in both Medici Ventures, L.P. and tZERO which meet the definition of variable interest entities; however, we are not the primary beneficiary of either entity for purposes of consolidation as we do not have the power (either explicit or implicit), through voting rights or otherwise, to direct the activities of Medici Ventures, L.P. or tZERO that most significantly impact their economic performance. Our investments in these variable interest entities totaled $342.5 million as of December 31, 2021, representing our maximum exposures to loss.

We record our proportionate share of Medici Ventures, L.P.'s reported net income or loss, which reflects the fair value changes of the underlying investments of the entity and any other operating income or losses of the entity, in Other income (expense), net in our consolidated statements of operations with corresponding adjustments to the carrying value of the asset. There is no difference between the carrying amount of our investment in the entity and the amount of underlying equity we have in the entity's net assets.

We have elected to apply the fair value option for valuing our direct minority interest in tZERO as we determined that accounting for our direct minority equity interest in tZERO under the fair value option would approximate the same valuation approach used by Medici Ventures, L.P. for valuing our indirect interest in tZERO and would be the most meaningful and transparent option for evaluating our continued exposure to the economics of tZERO. The methods and significant assumptions to estimate the fair value of tZERO include using guideline public companies for the market approach and discounted cash flow model for the income approach. Inputs for the market approach include assumptions made for the enterprise value to revenue multiple. Inputs for the income approach include assumptions made for discount rate, revenue growth rate, EBITDA margin, and discount period.

If such events or circumstances have occurred that may indicate the fair value of the security is less than its carrying value, we estimate the fair value of the security and recognize an impairment loss equal to the difference between the fair value of the security and its carrying value which is recorded in Other income (expense), net in our consolidated statements of operations.

We determine if an arrangement is a lease at inception. We account for lease agreements as either operating or finance leases depending on certain defined criteria. Operating leases are recognized in Operating lease right-of-use ("ROU") assets, Operating lease liabilities, current, and Operating lease liabilities, non-current on our consolidated balance sheets. Finance leases are included in Other long-term assets, net, Other current liabilities, and Other long-term liabilities on our consolidated balance sheets. Lease assets and liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of future payments. In certain of our lease agreements, we receive rent holidays and other incentives. We recognize lease costs on a straight-line basis over the lease term without regard to deferred payment terms, such as rent holidays, that defer the commencement date of required payments. Our lease terms may include options to extend or terminate the lease, and we adjust our measurement of the lease when it is reasonably certain that we will exercise that option. Lease payments used in measurement of the lease liability typically do not include executory costs, such as taxes, insurance, and maintenance, unless those costs can be reasonably estimated at lease commencement. Leasehold improvements are capitalized at cost and amortized over the lesser of their expected useful life or the life of the lease, without assuming renewal features, if any, are exercised. We do not separate lease and non-lease components for our leases.

Goodwill represents the excess of the purchase price paid over the fair value of the net assets acquired in business combinations. Goodwill is not amortized but is tested for impairment at least annually or when we deem that a triggering event has occurred. When evaluating whether goodwill is impaired, we make a qualitative assessment to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the qualitative assessment determines that it is more likely than not that its fair value is less than its carrying amount, we compare the fair value of the reporting unit to which the goodwill is assigned to its carrying amount. If the carrying amount exceeds its fair value, an impairment loss is recognized in an amount equal to the excess of the carrying amount over the fair value of the reporting unit, not to exceed the carrying amount of the goodwill. There were no impairments to goodwill recorded during the years ended December 31, 2021, 2020 and 2019 and no other changes to the carrying amount of goodwill during the years ended December 31, 2021 and 2020. Our goodwill balance of $6.2 million as of December 31, 2021 and 2020 is net of accumulated impairment losses and other adjustments of $3.3 million.

We capitalize and amortize intangible assets other than goodwill over their estimated useful lives unless such lives are indefinite. Intangible assets other than goodwill acquired separately from third-parties are capitalized at cost while such assets acquired as part of a business combination are capitalized at their acquisition-date fair value. Definite lived intangible assets are amortized using the straight-line method of amortization over their useful lives, with the exception of certain intangibles (such as acquired technology, customer relationships, and trade names) which are amortized using an accelerated method of amortization based on cash flows. These definite lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable as described below under Impairment of long-lived assets.

We review property and equipment, right-of-use assets, and other long-lived assets, including intangible assets other than goodwill, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. Recoverability is measured by a comparison of the assets' carrying amount to future undiscounted net cash flows the asset group is expected to generate. Cash flow forecasts are based on trends of historical performance and management's estimate of future performance, giving consideration to existing and anticipated competitive and economic conditions. If such asset group is considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds their fair values. There were no impairments to long-lived assets recorded during the years ended December 31, 2021, 2020 and 2019.

Revenue is recognized when, or as, control of a promised product or service transfers to a customer, in an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring those products or services. Revenue excludes taxes that have been assessed by governmental authorities and that are directly imposed on revenue-producing transactions between the Company and its customers, including sales and use taxes. Revenue recognition is evaluated through the following five-step process:

We derive our revenue primarily through our Website but may also derive revenue from sales of merchandise through other channels. Our revenue is derived primarily from merchandise sold at a point in time and shipped to customers. Merchandise sales are fulfilled with inventory sourced through our partners or from our owned inventory. The vast majority of our sales, however, are fulfilled from inventory sourced through our partners.

Revenue is recognized when control of the product passes to the customer, typically at the date of delivery of the merchandise to the customer or the date a service is provided and is recognized in an amount that reflects the expected consideration to be received in exchange for such goods or services. As such, customer orders are recorded as unearned revenue prior to delivery of products or services ordered. As we ship high volumes of packages through multiple carriers, we use estimates to determine which shipments are delivered and, therefore, recognized as revenue at the end of the period. Our delivery date estimates are based on average shipping transit times, which are calculated using the following factors: (i) the type of shipping carrier (as carriers have different in-transit times); (ii) the fulfillment source (either our warehouses, those warehouses we control, or those of our partners); (iii) the delivery destination; and (iv) actual transit time experience, which shows that delivery date is typically one to eight business days from the date of shipment. We review and update our estimates on a quarterly basis based on our actual transit time experience. However, actual shipping times may differ from our estimates.

Generally, we require authorization from credit card or other payment vendors whose services we offer to our customers (such as PayPal, Apple Pay, Klarna), or verification of receipt of payment, before we ship products to consumers or business purchasers. We generally receive payments from our customers before our payments to our suppliers are due. We do not recognize assets associated with costs to obtain or fulfill a contract with a customer.

Our merchandise sales contracts include terms that could cause variability in the transaction price for items such as discounts, credits, or sales returns. Accordingly, the transaction price for product sales includes estimates of variable consideration to the extent it is probable that a significant reversal of revenue recognized will not occur. At the time of sale, we estimate a sales return liability for the variable consideration based on historical experience, which is recorded within Accrued liabilities in the consolidated balance sheet. We record an allowance for returns based on current period revenues and historical returns experience. We analyze actual historical returns, current economic trends and changes in order volume and acceptance of our products when evaluating the adequacy of the sales returns allowance in any accounting period.

We evaluate the criteria outlined in ASC 606-10-55, Principal versus Agent Considerations, in determining whether it is appropriate to record the gross amount of merchandise sales and related costs or the net amount earned as commissions. When we are the principal in a transaction and control the specific good or service before it is transferred to the customer, revenue is recorded gross; otherwise, revenue is recorded on a net basis. Through contractual terms with our partners, we have the ability to control the promised goods or services and as a result record the majority of our revenue on a gross basis.

The Club O loyalty program allows members to earn Club O Reward dollars for qualifying purchases made on our Website. As such, the initial transaction price giving rise to the reward dollar is allocated to each separate performance obligation based upon its relative standalone selling price. In determining the stand-alone selling price, we incorporate assumptions about the redemption rates of loyalty points. We recognize revenue for Club O Reward dollars when customers redeem such rewards as part of a purchase on our Website.

We record the standalone value of reward dollars earned in unearned revenue at the time the reward dollars are earned. Club O Reward dollars expire 90 days after the customer's Club O membership expires. We recognize estimated reward dollar breakage, to which we expect to be entitled, over the expected redemption period in proportion to actual redemptions by customers.

Customer orders are recorded as unearned revenue when payment is received prior to delivery of products or services ordered. We record amounts received for Club O membership fees as unearned revenue and we recognize it ratably over the membership period. We record Club O Reward dollars earned from purchases as unearned revenue at the time they are earned based upon the relative standalone selling price of the Club O Reward dollar and we recognize it as revenue in proportion to the estimated pattern of rights exercised by the customer. If reward dollars are not redeemed, we recognize revenue upon expiration. In addition, we sell gift cards and record related unearned revenue at the time of the sale. We sell gift cards without expiration dates and we recognize revenue from a gift card upon redemption of the gift card. The unredeemed portion of our gift cards are recognized in revenue over the expected redemption period based upon the estimated pattern of rights exercised by the customer, if the gift cards are not subject to escheat laws.

We inspect returned items when they arrive at our processing facilities. We refund the full cost of the merchandise returned and all original shipping charges if the returned item is defective or we or our partners have made an error, such as shipping the wrong product. If the return is not a result of a product defect or a fulfillment error and the customer initiates a return of an unopened item within 30 days of delivery, for most products we refund the full cost of the merchandise minus the original shipping charge and actual return shipping fees. However, we reduce refunds for returns initiated more than 30 days after delivery or that are received at our returns processing facility more than 45 days after initial delivery. If our customer returns an item that has been opened or shows signs of wear, we issue a partial refund minus the original shipping charge and actual return shipping fees.

We expense the costs of producing advertisements the first time the advertising takes place and expense the cost of communicating advertising in the period during which the advertising space or airtime is used. Internet advertising expenses are recognized as incurred based on the terms of the individual agreements, which are generally: 1) a commission for traffic driven to our Website that generates a sale or 2) a referral fee based on the number of clicks on keywords or links to our Website generated during a given period. Advertising expense is included in Sales and marketing expenses in our consolidated statements of operations. Prepaid advertising is included in Prepaids and other current assets in our consolidated balance sheets.

We measure compensation expense for our outstanding unvested restricted stock awards at fair value on the date of grant and recognize compensation expense over the service period for awards at the greater of a straight-line basis or on an accelerated schedule when vesting of the share-based awards exceeds a straight-line basis. When an award is forfeited prior to the vesting date, we recognize an adjustment for the previously recognized expense in the period of the forfeiture. See Note 16—Stock-Based Awards.

We use the Black-Scholes option pricing model to determine the fair value of our employee stock purchase plan shares. The determination of the fair value of stock-based payment awards on the date of grant using an option pricing model is affected by our stock price as well as assumptions regarding a number of complex and subjective variables. These variables include our expected stock price volatility over the expected term of the awards, actual and projected employee stock option exercise behaviors, a risk-free interest rate and any expected dividends.

In the normal course of business, we are involved in legal proceedings and other potential loss contingencies. We accrue a liability for such matters when it is probable that a loss has been incurred and the amount, or range of amounts, can be reasonably estimated. When only a range of probable loss can be estimated, the most probable amount in the range is accrued. If no amount within this range is a better estimate than any other amount within the range, the minimum amount in the range is accrued. We expense legal fees as incurred (See Note 13—Commitments and Contingencies).

Income taxes are accounted for under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statements and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

We recognize deferred tax assets to the extent that we believe these assets are more likely than not to be realized. In evaluating our ability to recover our deferred tax assets within the jurisdiction from which they arise, we consider all available positive and negative evidence, including projected future taxable income, scheduled reversals of our deferred tax liabilities, tax planning strategies, and results of recent operations. Our projections of future taxable income are subject to change due to economic, political, and other conditions, such as the COVID-19 pandemic, and judgment is required in determining our ability to use our deferred tax assets.

We record uncertain tax positions in accordance with ASC 740 on the basis of a two-step process whereby (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. We recognize interest and penalties related to unrecognized tax benefits within the income tax expense line in the accompanying consolidated income statements. Accrued interest and penalties are included within the related tax liability line in our consolidated balance sheets.

Our Blockchain Voting Series A Preferred Stock, par value $0.0001 per share (the "Series A Preferred"), Digital Voting Series A-1 Preferred stock, par value $0.0001 per share (the "Series A-1 Preferred"), and our Voting Series B Preferred stock, par value $0.0001 per share (the "Series B Preferred" together with the Series A Preferred stock and the Series A-1 Preferred stock, collectively, the "Preferred Shares") are considered participating securities, and as a result, net income (loss) per share is calculated using the two-class method. Under this method, we give effect to preferred dividends and then allocate remaining net income (loss) attributable to our stockholders to both common shares and participating securities (based on the percentages outstanding) in determining net income (loss) per common share.

Diluted net income (loss) per share is computed by dividing net income (loss) attributable to common shares (after allocating between common shares and participating securities) by the weighted average number of common and potential common shares outstanding during the period (after allocating total dilutive shares between our common shares outstanding and our preferred shares outstanding). Potential common shares, comprising incremental common shares issuable from the employee stock purchase plan and restricted stock awards are included in the calculation of diluted net income (loss) per common share to the extent such shares are dilutive.

In December 2019, the FASB issued ASU 2019-12, Income Taxes ("Topic 740")—Simplifying the Accounting for Income Taxes, which removes certain exceptions to the general principles in Topic 740 and amends existing guidance to improve consistent application. We adopted the changes under the new standard on January 1, 2021. The implementation of ASU 2019-12 did not have a material impact on our consolidated financial statements and disclosures.

In January 2020, the FASB issued ASU 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815, which clarifies the interaction of the accounting for equity securities under Topic 321, the accounting for equity method investments in Topic 323, and the accounting for certain forward contracts and purchased options in Topic 815. We adopted the changes under the new standard on January 1, 2021. The implementation of ASU 2020-01 did not have a material impact on our consolidated financial statements and disclosures.

In October 2020, the FASB issued ASU 2020-10, Codification Improvements, which amends and provides Codification improvements in order to either clarify the Codification or correct unintended application of guidance that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. We adopted the changes under the new standard on January 1, 2021. The implementation of ASU 2020-10 did not have a material impact on our consolidated financial statements and disclosures.
