Accounting Policies [Abstract]

ACCOUNTING POLICIES

Principles of consolidation

The accompanying consolidated financial statements include our accounts and the accounts of our wholly-owned subsidiaries and subsidiaries for which we exercise control. All intercompany account balances and transactions have been eliminated in consolidation. Included in our consolidated financial statements are the financial results of Bitsy, Inc. from the acquisition date of January 1, 2019, Verify Investor, LLC from the date of acquisition on February 12, 2018, and Mac Warehouse, LLC from the date of acquisition on June 25, 2018.

Use of estimates

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 of fixed assets and internally-developed software, goodwill valuation, intangible asset valuation, equity security valuation, income taxes, stock-based compensation, performance-based compensation, self-funded health insurance liabilities, and contingencies. Although these estimates are based on our best knowledge of current events and actions that we may undertake in the future, actual results could differ materially from these estimates.

Cash equivalents

We classify all highly liquid instruments, including instruments with a remaining maturity of three months or less at the time of purchase, as cash equivalents. Cash equivalents were $2.8 million and $3.1 million at December 31, 2019 and 2018, respectively.

Restricted cash

We consider cash that is legally restricted and cash that is held as compensating balances for credit arrangements as restricted cash.

Fair value of financial instruments

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.


•	Level 1—Quoted prices for identical instruments in active markets;


•	Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and


•	Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

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).

The following tables summarize our assets and liabilities measured at fair value on a recurring basis using the following levels of inputs as of December 31, 2019 and 2018, as indicated (in thousands):

___________________________________________


(1)	— Trading securities held in a rabbi trust are included in Prepaids and other current assets and Other long-term assets, net in the consolidated balance sheets.


(2)	— Non-qualified deferred compensation in a rabbi trust is included in Accrued liabilities and Other long-term liabilities in the consolidated balance sheets.

Accounts receivable, net

Accounts receivable consist primarily of carrier rebates, 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. From time to time, we grant credit to some of our business customers on normal credit terms (typically 30 days). We maintain an allowance for doubtful accounts receivable based upon our business customers' financial condition and payment history, and our historical collection experience and expected collectability of accounts receivable. The allowance for doubtful accounts receivable was $2.5 million and $2.1 million at December 31, 2019 and 2018, respectively.

Concentration of credit risk

At December 31, 2019 and 2018, one bank held the majority of our cash and cash equivalents. Our cash equivalents primarily consist of money market securities which are uninsured. We do not believe that, as a result of this concentration, we are subject to any unusual financial risk beyond the normal risk associated with commercial banking relationships.

Inventories, net

Inventories, net include merchandise purchased for resale 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.

Prepaids and other current assets

Prepaids and other current assets represent expenses paid prior to receipt of the related goods or services, including advertising, license fees, maintenance, packaging, insurance, prepaid inventories, other miscellaneous costs, and cryptocurrency-denominated assets ("cryptocurrencies"). See Cryptocurrencies below.

Cryptocurrencies

We hold cryptocurrency-denominated assets ("cryptocurrencies") such as bitcoin and we include them in Prepaids and other current assets in our consolidated balance sheets. Our cryptocurrencies were $2.6 million and $2.4 million at December 31, 2019 and 2018, respectively, and are recorded at cost less impairment.

We recognize impairment on these assets caused by decreases in market value, determined by taking quoted prices from various digital currency exchanges with active markets, whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. See Fair value of financial instruments above. Such impairment in the value of our cryptocurrencies is recorded in General and administrative expense in our consolidated statements of operations. Impairments on cryptocurrencies were $334,000, $10.5 million, and $0 during the years ended December 31, 2019, 2018 and 2017, respectively.

Gains and losses realized upon sale of cryptocurrencies are also recorded in General and administrative expense in our consolidated statements of operations. We occasionally use our cryptocurrencies to purchase other cryptocurrencies. Gains and losses realized with these non-cash transactions are also recorded in General and administrative expense in our consolidated statements of operations. These non-cash transactions as well as gains (losses) from cryptocurrencies received through tZERO's offering of tZERO's Preferred Equity Tokens, Series A ("TZROP") are also presented as an adjustment to reconcile Consolidated net loss to Net cash used in operating activities in our consolidated statements of cash flows. Further, the proceeds from the sale of cryptocurrencies received through tZERO's offering of TZROP are presented as a financing activity in our consolidated statements of cash flows due to its near immediate conversion into cash and its economic similarity to the receipt of cash proceeds under tZERO's offering of TZROP. Realized gains on sale of cryptocurrencies were $569,000, $8.4 million, and $0 during the years ended December 31, 2019, 2018, and 2017, respectively.

Property and equipment, net

Property and equipment are recorded at cost and stated net of depreciation and amortization. Property and equipment are depreciated using the straight-line method over the estimated useful lives of the related assets or the term of the related finance lease, whichever is shorter, as follows:



	Life (years)
Building	40
Land improvements	20
Building machinery and equipment	15-20
Furniture and equipment	5-7
Computer hardware	3-4
Computer software, including internal-use software and website development	2-4

Leasehold improvements are amortized over the shorter of the term of the related leases or estimated useful lives.

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.

During the years ended December 31, 2019, 2018, and 2017, we capitalized $13.0 million, $19.3 million, and $9.6 million, respectively, of costs associated with internal-use software and website development, both developed internally and acquired externally. Depreciation of internal-use software and website development for the years ended December 31, 2019, 2018, and 2017 was $12.9 million, $13.8 million, and $15.9 million, respectively.

Depreciation expense is classified within the corresponding operating expense categories in the consolidated statements of operations as follows (in thousands):



	Year ended December 31,
	2019		2018		2017
Cost of goods sold—retail	$	687	$	354	$	307
Technology	20,798		21,894		24,604
General and administrative	4,777		4,163		3,937
Total depreciation	$	26,262	$	26,411	$	28,848

Upon sale or retirement of assets, cost and related accumulated depreciation and amortization are removed from the balance sheet and the resulting gain or loss is reflected in our consolidated statements of operations.

Equity securities and marketable securities under ASC 321

At December 31, 2019, we held minority interests (less than 20%) in certain public and privately held entities, accounted for under ASC Topic 321, Investments—Equity Securities ("ASC 321"), which are included in Equity securities and Marketable securities in our consolidated balance sheets. We measure our ASC 321 equity securities and marketable securities at fair value, unless there is no readily determinable fair value for the underlying security. Where there is no readily determinable fair value, we have elected the measurement alternative described in ASC 321 and below. Dividends received are reported in earnings if and when received. We review our securities individually for impairment by evaluating if events or circumstances have occurred that may indicate the fair value of the security is less than its carrying value. If such events or circumstances have occurred, 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. In such cases, the estimated fair value of the security is determined using unobservable inputs including assumptions by the investee's management including quantitative information such as lower valuations in recently completed or proposed financings. These inputs are classified as Level 3. Because several of these private companies are in the early startup or development stages, these entities are subject to potential changes in cash flows, valuation, as well as inability to raise additional capital which may be necessary for the liquidity needed to support their operations.

Certain of our equity securities lack readily determinable fair values and therefore the securities are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar equity securities of the same issuer. The carrying amount of our equity securities without readily determinable fair values was approximately $3.9 million and $17.7 million at December 31, 2019 and 2018, respectively. Cumulative downward adjustments for price changes and impairments for our equity securities without readily determinable fair values held at December 31, 2019 were $6.2 million, and the cumulative upward adjustments for price changes to equity securities were $958,000 as of December 31, 2019. The impairments and downward adjustments for the period related to equity securities without readily determinable fair values at December 31, 2019, 2018 and 2017 is as follows (in thousands):



	Year ended December 31,
	2019			2018			2017
Impairments and downward adjustments of equity securities without readily determinable fair values	$	(5,708	)	$	(536	)	$	(5,487	)
Upward adjustments of equity securities without readily determinable fair values	$	—		$	958		$	—

Certain of these equity securities and our marketable securities, which had a carrying value of $11.1 million at December 31, 2019 and $2.6 million at December 31, 2018, respectively, are carried at fair value based on Level 1 inputs. See Fair value of financial instruments above. The portion of unrealized gains and losses for the period related to equity securities with readily determinable fair value still held at December 31, 2019, 2018 and 2017 is as calculated as follows (in thousands):



	Year ended December 31,
	2019		2018		2017
Net gains recognized during the period on equity securities and marketable securities	$	3,336	$	136	$	—
Less: Net gains recognized during the period on equity securities and marketable securities sold	848		—		—
Unrealized gains recognized during the reporting period on equity securities and marketable securities still held at the reporting period	$	2,488	$	136	$	—

Equity securities accounted for under the equity method under ASC 323

At December 31, 2019, we held minority interests in privately held entities, 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 either holding more than a 20% voting interest in the entity or through our representation on the entity's board of directors. For certain of these entities, we provide developer services. For the years ended December 31, 2019, 2018 and 2017 we recognized $2.7 million, $2.4 million and $159,000 of developer service revenue, respectively, in Other revenue on our consolidated statements of operations.

The following table includes our equity securities accounted for under the equity method and related ownership interest as of December 31, 2019:



	Ownership interest
Bitt Inc.	21%
Boston Security Token Exchange LLC	50%
Chainstone Labs, Inc.	29%
FinClusive Capital, Inc.	10%
GrainChain, Inc.	18%
Minds, Inc.	24%
PeerNova, Inc.	11%
SettleMint NV	29%
Spera, Inc.	19%
VinX Network Ltd.	29%
Voatz, Inc.	20%

Based on the nature of our ownership interests and the extent of our contributed capital, we have variable interests in certain of these entities. However, we have insufficient voting rights or other means to influence the investee such that we do not have power to direct the investee's activities that most significantly impact the economic performance of each entity. Further, we are not the investee's primary beneficiary and we therefore do not consolidate the investee in our financial statements. Our investments, plus any loans, off-balance sheet commitments, and other subordinated financial support related to these variable interest entities totaled $24.2 million and $25.9 million as of December 31, 2019 and 2018, respectively, representing our maximum exposures to loss.

The carrying amount of our equity method securities was approximately $37.3 million and $40.1 million at December 31, 2019 and 2018, respectively. The carrying value of our equity method securities exceeded the amount of the underlying equity in net assets of our equity method securities and the difference was primarily related to goodwill and the fair value of intangible assets. The basis difference attributable to amortizable intangible assets is amortized over their estimated useful lives. We record our proportionate share of the net income or loss from our equity method securities and the amortization of the basis difference related to intangible assets in Other income (expense), net in our consolidated statements of operations with corresponding adjustments to the carrying value of the asset. We review our securities individually for impairment by evaluating if events or circumstances have occurred that may indicate the fair value of the security is less than its carrying value. If such events or circumstances have occurred, 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.

The following table summarizes the net losses recognized on equity method securities recorded in Other income (expense), net in our consolidated statements of operations for the years ended December 31, 2019, 2018 and 2017 (in thousands):



	Year ended December 31,
	2019		2018		2017
Net loss recognized on our proportionate share of the net losses of our equity method securities and amortization of the basis difference	$	7,734	$	3,869	$	508
Impairments on equity method securities	1,382		—		—
Net loss recognized during the period on equity method securities sold	524		—		—

Noncontrolling interests

Our wholly-owned subsidiary, Medici Ventures, Inc. ("Medici Ventures"), conducts its primary business through its majority-owned subsidiaries, tZERO Group, Inc. ("tZERO"), formerly tØ.com, Inc., which includes a financial technology company, two related registered broker-dealers, an accredited investor verification company, and certain strategic interests in other entities which support or align with tZERO's objectives and strategies, and Medici Land Governance Inc. ("MLG"). Medici Ventures, tZERO, MLG, and their respective consolidated subsidiaries are included in our consolidated financial statements. Intercompany transactions have been eliminated and the amounts of contributions and gains or losses that are attributable to the noncontrolling interests are disclosed in our consolidated financial statements.

Leases

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 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 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.

Treasury stock

We account for treasury stock of our common shares under the cost method and include treasury stock as a component of stockholders' equity.

Goodwill

Goodwill represents the excess of the purchase price paid over the fair value of the net assets acquired in business combinations (See Note 3. 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, 2019, 2018 and 2017.

The following table provides information about changes in the carrying amount of goodwill for the periods presented (in thousands):



	Amount
Balances as of December 31, 2017 (1)	$	14,698
Goodwill acquired during year	8,197
Balances as of December 31, 2018 (2)	22,895
Goodwill acquired during year	1,685
Purchase price adjustment	2,540
Balances as of December 31, 2019 (3)	$	27,120

___________________________________________

(1), (2), (3) — Goodwill is net of accumulated impairment loss and other adjustments of $3.3 million.

Intangible assets other than goodwill

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.

Intangible assets, net consist of the following (in thousands):



	December 31,
	2019			2018
Intangible assets subject to amortization, gross (1)	$	30,284		$	29,099
Less: accumulated amortization of intangible assets subject to amortization	(18,528		)	(15,729		)
Total intangible assets, net	$	11,756		$	13,370

___________________________________________

(1) — At December 31, 2019, the weighted average remaining useful life for intangible assets subject to amortization was 5.55 years.

Amortization of intangible assets other than goodwill is classified within the corresponding operating expense categories in our consolidated statements of operations as follows (in thousands):



	Year ended December 31,
	2019			2018		2017
Technology	$	3,726		$	3,424	$	3,620
Sales and marketing	64			460		83
General and administrative	(458		)	1,402		296
Total amortization	$	3,332		$	5,286	$	3,999

General and administrative amortization above was net of reversals due to adjustments to the purchase price allocation for Mac Warehouse, as further described in Note 3. Business Combinations.

Estimated amortization expense for the next five years is: $3.7 million in 2020, $3.3 million in 2021, $2.1 million in 2022, $1.6 million in 2023, $804,000 in 2024 and $323,000 thereafter.

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. See the Cryptocurrencies section above for our impairment policy over cryptocurrencies. Recoverability is measured by 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.

For the year ended December 31, 2019, we realized a $1.4 million impairment loss included in General and administrative expense in our consolidated statements of operations related to certain patents held by our Medici Ventures segment. The estimated fair value of the patents were determined based on Level 3 inputs, which were unobservable (see the Fair value of financial instruments section above), including market participant assumptions for similar assets in an inactive market. For the year ended December 31, 2018, we realized a $6.0 million loss included in General and administrative expense in our consolidated statements of operations related to certain patents held by our Medici Ventures segment. The estimated fair value of the patents were determined based on Level 3 inputs, which were unobservable (see the Fair value of financial instruments section above), including market participant assumptions for similar assets in an inactive market. In conjunction with our annual assessment, we concluded the remaining useful life of these licenses were zero based on current contractual arrangements. There were no impairments to long-lived assets recorded during the year ended December 31, 2017.

Other long-term assets, net

Other long-term assets, net consist primarily of long-term prepaid expenses, deposits, and assets acquired under finance leases.

Revenue recognition

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:

1) identification of the contract with a customer;

2) identification of the performance obligations in the contract;

3) determination of the transaction price;

4) allocation of the transaction price to the performance obligations in the contract; and

5) recognition of revenue when or as a performance obligation is satisfied.

Product Revenue

We derive our revenue primarily from our retail business through our Website but may also derive revenue from sales of merchandise through offline and other channels. Our Retail 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, depending on the most efficient means of fulfilling the customer contract. The 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 deferred revenue prior to delivery of products or services ordered. As we ship high volumes of packages through multiple carriers, it is not practical for us to track the actual delivery date of each shipment. Therefore, 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), or verification of receipt of payment, before we ship products to consumers or business purchasers. From time to time we grant credit to our business purchasers with normal credit terms (typically 30 days). 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.

Shipping and handling is considered a fulfillment activity, as it takes place prior to the customer obtaining control of the merchandise, and fees charged to customers are included in net revenue upon completion of our performance obligation. We present revenue net of sales taxes, discounts, and expected refunds.

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 retail revenue on a gross basis.

Our Other revenue occurs primarily through our broker-dealer subsidiaries in our tZERO segment. We evaluate the revenue recognition criteria above for our broker-dealer subsidiaries and we recognize revenue based on the gross amount of consideration that we expect to receive on securities transactions (commission revenue) on a trade date basis.

Club O loyalty program

We have a customer loyalty program called Club O for which we sell annual memberships. For Club O memberships, we record membership fees as deferred revenue and we recognize revenue ratably over the membership period.

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 deferred 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. Upon adoption of Topic 606, Revenue from Contracts with Customers, on January 1, 2018, we began classifying the breakage income related to Club O Reward dollars and gift cards as a component of Retail revenue in our consolidated statements of operations rather than as a component of Other income (expense), net. Breakage included in revenue was $4.2 million and $5.6 million for the years ended December 31, 2019 and 2018, respectively. In 2018 we also recognized a cumulative adjustment that reduced Accumulated deficit by approximately $5.0 million upon adoption related to the unredeemed portion of our gift cards and loyalty program rewards.

Our total deferred revenue related to the outstanding Club O Reward dollars was $6.7 million and $6.9 million at December 31, 2019 and December 31, 2018, respectively. The timing of revenue recognition of these reward dollars is driven by actual customer activities, such as redemptions and expirations.

Advertising Revenue

Advertising revenues are derived primarily from sponsored links and display advertisements that are placed on our Website, distributed via email, or sent out as direct mailers. Advertising revenue is recognized in Retail revenue when the advertising services are rendered. Advertising revenues were less than 2% of total net revenues for all periods presented.

Revenue Disaggregation

Disaggregation of revenue by major product line is included in Segment Information in Note 21. Business Segments.

Deferred Revenue

When the timing of our provision of goods or services is different from the timing of the payments made by our customers, we recognize a contract liability (customer payment precedes performance).

Customer orders are recorded as deferred revenue prior to delivery of products or services ordered. We record amounts received for Club O membership fees as deferred revenue and we recognize it ratably over the membership period. We record Club O Reward dollars earned from purchases as deferred 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 Retail revenue in proportion to the estimated pattern of rights exercised by the customer. If reward dollars are not redeemed, we recognize Retail revenue upon expiration. In addition, we sell gift cards and record related deferred 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. For the unredeemed portion of our gift cards and loyalty program rewards, we will recognize Retail revenue over the expected redemption period based upon the estimated pattern of rights exercised by the customer.

The following table provides information about deferred revenue from contracts with customers, including significant changes in deferred revenue balances during the period (in thousands).

Sales returns allowance

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.

Revenue is recorded net of estimated returns. 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.

The following table provides additions to and deduction from the sales returns allowance (in thousands):

Cost of goods sold

Our Retail cost of goods sold includes product costs, warehousing costs, outbound shipping costs, handling and fulfillment costs, customer service costs, and credit card fees, and is recorded in the same period in which related revenues have been recorded. Our Other cost of goods sold primarily consists of exchange fees, clearing agent fees, and other exchange fees from our broker-dealer subsidiaries in our tZERO segment. These fees are primarily for executing, processing, and settling trades on exchanges and other venues. These fees fluctuate based on changes in trade and share volumes, rate of clearance fees charged by clearing brokers, and exchanges (in thousands, except for percentages).

Advertising expense

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 and totaled $124.3 million, $249.7 million and $164.6 million during the years ended December 31, 2019, 2018 and 2017, respectively. Prepaid advertising (included in Prepaids and other current assets in the accompanying consolidated balance sheets) was $138,000 and $961,000 at December 31, 2019 and 2018, respectively.

Stock-based compensation

We measure compensation expense for all outstanding unvested share-based 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 15. Stock-Based Awards.

Loss contingencies

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 12. Commitments and Contingencies).

Income taxes

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.

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.

Net loss per share

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 loss per share is calculated using the two-class method. Under this method, we give effect to preferred dividends and then allocate remaining net loss attributable to our stockholders to both common shares and participating securities (based on the percentages outstanding) in determining net loss per common share.

Basic net loss per common share is computed by dividing net loss attributable to common shares (after allocating between common shares and participating securities) by the weighted average number of common shares outstanding during the period.

Diluted net loss per share is computed by dividing net 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 upon the exercise of stock options, warrants, and restricted stock awards are included in the calculation of diluted net loss per common share to the extent such shares are dilutive. Net loss attributable to common shares is adjusted for options and restricted stock awards issued by our subsidiaries when the effect of our subsidiary's diluted earnings per share is dilutive.

On July 30, 2019, we announced that our Board of Directors had declared a dividend (the "Dividend") payable in shares of our Series A-1 Preferred stock. The Dividend is payable at a ratio of 1:10, meaning that one share of Series A-1 Preferred stock will be issued for every ten shares of common stock, Series A-1 Preferred stock or Series B Preferred stock held by all holders of such shares as of the record date for the Dividend. As of December 31, 2019, the Dividend had not been distributed.

Recently adopted accounting standards

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. We adopted the new standard on January 1, 2018 with a cumulative adjustment that reduced Accumulated deficit by approximately $5.0 million as opposed to retrospectively adjusting prior periods. The adjustment primarily relates to the unredeemed portion of our gift cards and loyalty program rewards, which we will recognize over the expected redemption period, rather than waiting until the likelihood of redemption becomes remote or the rewards expire. We have also updated revenue disclosures in the notes to our financial statements as required under the new standard.

The implementation did not impact our gross and net recognition for our revenue transactions. In addition, we continue to recognize revenue related to merchandise sales upon delivery to our customers. However, we now present breakage on our Club O Rewards and gift cards in Retail revenue in our consolidated statement of operations rather as a component of Other income (expense), net.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements. The new standard establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement.

We adopted the new standard on January 1, 2019. A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. If an entity chooses the second option, the transition requirements for existing leases also apply to leases entered into between the date of initial application and the effective date. The entity must also recast its comparative period financial statements and provide the disclosures required by the new standard for the comparative periods. We adopted the new standard on January 1, 2019 and thus used the effective date as our date of initial application. Consequently, financial information has not been updated and the disclosures required under the new standard are not provided for dates and periods before January 1, 2019. Upon adoption we recognized cumulative opening lease liabilities of approximately $35.1 million and operating right-of-use assets of approximately $31.0 million which were reflected as non-cash items in the consolidated statements of cash flows. The difference of $4.2 million represented deferred rent for leases that existed as of the date of adoption, which was an offset to the opening balance of right-of-use assets.

The new standard provides a number of optional practical expedients in transition. We elected the "package of practical expedients", which permits us to not reassess under the new standard our prior conclusions about lease identification, lease classification, and initial direct costs as well as the practical expedient pertaining to land easements. We did not elect the use-of-hindsight practical expedient. The new standard also provides practical expedients for an entity's ongoing accounting. We elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, we did not recognize ROU assets or lease liabilities, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. We also elected the practical expedient to not separate lease and non-lease components for all of our leases.

The standard had a material effect on our financial statements, primarily related to (1) the recognition of new ROU assets and lease liabilities on our balance sheet for our warehouse, office, data center, and equipment operating leases; and (2) providing significant new disclosures about our leasing activities. The additional operating liabilities on our consolidated balance sheets were recognized based on the present value of the remaining minimum rental payments under current leasing standards for our existing operating leases, discounted by our incremental borrowing rate for borrowings of a similar duration on a fully secured basis, with corresponding ROU assets of approximately the same amount.

In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting; which aligns the measurement and classification guidance for share-based payments to nonemployees with the guidance for share-based payments to employees, with certain exceptions. Under the guidance, the measurement of equity-classified nonemployee awards will be fixed at the grant date. We adopted the changes under the new standard on January 1, 2019 on a prospective basis. The implementation of ASU 2018-07 did not have a material impact on our consolidated financial statements and related disclosures.

Recently issued accounting standards

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which revises how entities account for credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. For public entities, ASU 2016-13 is required to be adopted for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. The Company has completed its analysis of the impact of this guidance and the adoption of this standard will not have a material impact on our consolidated financial statements and related disclosures.

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. For public entities, ASU 2019-12 is required to be adopted for annual periods beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. Management is currently evaluating the impact of the adoption of this ASU on our consolidated financial statements and related disclosures.

We sell our products and services through our Internet websites located at www.overstock.com, www.o.co and www.o.biz (referred to collectively as the "Website"). Although our three websites are located at different domain addresses, the technology, equipment, and processes supporting the Website and the process of order fulfillment described herein are the same for all three websites. In late 2014, we began working on initiatives to develop and advance blockchain technology, which initiatives we refer to collectively as Medici. Our Medici business initiatives seek to leverage the security, transparency and immutability of cryptographically protected and distributed ledgers, such as blockchains, and are focused on solving important problems, including financial transaction issues, particularly in the area of securities settlement. Our Medici business initiatives include our wholly-owned subsidiary, Medici Ventures, Inc. ("Medici Ventures"), which conducts a majority of its business through its majority-owned subsidiary tZERO Group, Inc. ("tZERO"), formerly tØ.com, Inc., a financial technology company pursuing potential financial applications of blockchain technologies as well as non-blockchain businesses. Medici Ventures currently holds equity interests in several technology companies whose focuses include commercial blockchain applications for identity and social media, property and land, money and banking, capital markets, supply chain, and voting. Basis of presentation We have prepared the accompanying consolidated financial statements pursuant to generally accepted accounting principles in the United States ("GAAP"). Preparing financial statements requires us to make estimates and assumptions that affect the amounts that are reported in the consolidated financial statements and accompanying disclosures. Although these estimates are based on our best knowledge of current events and actions that we may undertake in the future, our actual results may be different from our estimates. The results of operations presented herein are not necessarily indicative of our results for any future period. For purposes of comparability, we reclassified certain immaterial amounts in the prior periods presented to conform with the current year presentation.
