Summary of significant accounting policies | 2. Summary of significant accounting policies Basis of presentation The accompanying interim condensed consolidated financial statements and related notes for the three months ended March 31, 2021 and 2020 are unaudited. The unaudited interim condensed consolidated financial information has been prepared in accordance with the rules and regulations of the SEC for interim financial information. Accordingly, they do not include all information and footnotes required by generally accepted accounting principles (“GAAP”) in the United States of America (“U.S.”) for complete financial statements. These financial statements should be read in conjunction with the audited consolidated financial statements and the accompanying notes for the year ended December 31, 2020 contained in our annual report on Form 10-K filed with the SEC on March 1, 2021, as amended through the Form 10-K/A filed with the SEC on April 28, 2021. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and in the opinion of management, reflect all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of our results of operations for the three months ended March 31, 2021 and 2020, our cash flows for the three months ended March 31, 2021 and 2020, and our financial position as of March 31, 2021. The year-end balance sheet data was derived from audited consolidated financial statements but does not include all disclosures required by GAAP. Interim results are not necessarily indicative of the results to be expected for an entire year or any other future year or interim period. In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging Contracts in Entity’s Own Equity (Subtopic 815-40), which eliminates the beneficial conversion and cash conversion accounting models for convertible instruments, amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions, and modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted EPS calculation. The standard is effective for annual periods beginning after December 15, 2021, and interim periods within those reporting periods. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those reporting periods. The standard can be adopted under the modified retrospective method or the full retrospective method. We adopted ASU 2020-06 on January 1, 2021 under the modified retrospective method. Results for reporting periods beginning on January 1, 2021 are presented under ASU 2020-06, while prior period amounts are not adjusted. Adoption of ASU 2020-06 required us to record a cumulative effect adjustment, net of tax, to accumulated deficit of $6,566 on January 1, 2021. In addition, the adoption of the standard resulted in the following changes to the consolidated balance sheet as of January 1, 2021: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | January 1, 2021 |  | Adjustment for |  | January 1, 2021
​ | ​ | (Unadjusted) | ​ | Adoption | ​ | (Adjusted)
Property and equipment, net | ​ | $ | 406,328 | ​ | $ | (6,076) | ​ | $ | 400,252
Long-term debt | ​ | $ | 171,695 | ​ | $ | 27,279 | ​ | $ | 198,974
Additional paid-in capital | ​ | $ | 241,868 | ​ | $ | (39,921) | ​ | $ | 201,947
​ The changes to the consolidated balance sheet as of January 1, 2021 were primarily due to the following factors: (i) reclassification of the equity component of our Convertible Notes related to the cash conversion feature to a liability thereby eliminating the debt discount; (ii) reclassification of the debt issuance costs for the equity component of our Convertible Notes to a liability; (iii) adjustment of the amount of interest expense capitalized as part of our property and equipment; and (iv) reversal of $5,686 of income tax benefit related to the equity component of the Convertible Notes that was recorded as additional paid-in capital. On January 1, 2021, we also reversed $27,949 of gross deferred tax liabilities related to the equity component of our Convertible Notes. The adoption of ASU 2020-06 did not have any impact on our net deferred tax as of January 1, 2021 due to the valuation allowance. Effective January 1, 2021, we calculate the dilutive effect of the Convertible Notes on our diluted EPS using the if-converted method. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes. The standard removes certain ASC 740 exceptions to reduce the cost and complexity of its application including: i) the exception to the “with-and-without” approach for intraperiod tax allocation when there was a loss from continuing operations and income or a gain from other items such as discontinued operations of other comprehensive income; ii) two exceptions with respect to accounting for outside basis differences of equity method investments and foreign subsidiaries; and iii) the exception to limit the income tax benefit recognized in the interim period in cases where the year-to-date loss exceeded the anticipated loss for the year. The standard also clarified and amended existing guidance including, but not limited to: i) when a step-up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill was originally recognized and when it should be considered a separate transaction; and ii) accounting for tax effects, both deferred and current, in the interim period that includes the enactment date. The standard is effective for annual periods beginning after December 15, 2020, and interim periods within those reporting periods. Early adoption is permitted with any adjustments reflected as of the beginning of the fiscal year of adoption. We adopted ASU 2019-12 on January 1, 2020 and the adoption of this standard did not have a material impact on our condensed consolidated financial statements. In August 2018, the FASB issued 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, which requires customers to apply the same criteria for capitalizing implementation costs incurred in a cloud computing arrangement that is hosted by the vendor as they would for an arrangement that has a software license. The standard is effective for interim and annual periods beginning after December 15, 2019 and early adoption is permitted. The standard can be adopted prospectively or retrospectively. We adopted ASU 2018-15 on January 1, 2020 on a prospective basis for any new implementation costs incurred in a cloud computing arrangement that is hosted by the vendor. The adoption of this standard did not have a material impact on our condensed consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments —Credit Losses (Topic 326), which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar investments) and net investments in leases recognized by the lessor in accordance with ASC 842 on leases. In addition, the standard made changes to the accounting for available-for-sale debt securities. One such change is to require credit losses to be presented as an allowance rather than as a write-down on available-for-sale debt securities. Available-for-sale accounting recognizes that values may be realized either through collection of contractual cash flows or through the sale of the security. Therefore the amendments limit the amount of the allowance for credit losses to the amount by which fair value is below amortized cost because the classification as available-for-sale is premised on an investment strategy that recognizes that the investment could be sold at fair value, if cash collection would result in the realization of an amount less than fair value. The standard is effective for interim and annual periods beginning after December 15, 2019 and early adoption is permitted. The standard will be adopted under the modified-retrospective approach with the prospective transition approach required for debt securities for which an other-than-temporary impairment had been recognized before the effective date. We adopted ASU 2016-13 on January 1, 2020 and the adoption of this standard did not have a material impact on our condensed consolidated financial statements. Principles of consolidation The unaudited condensed consolidated financial statements include our accounts and the accounts of our majority owned subsidiaries. We consolidate our 70% ownership of Chicago Concourse Development Group, LLC and our 75% ownership of Boingo Holding Participacoes Ltda. in accordance with ASC 810, Consolidation. Other parties’ interests in consolidated entities are reported as non-controlling interests. All intercompany balances and transactions have been eliminated in consolidation. Marketable securities Our marketable securities consist of available-for-sale securities with original maturities exceeding three months. According to ASC 320, Investments—Debt and Equity Securities, we have classified securities, which have readily determinable fair values and are highly liquid, as short-term because such securities are expected to be realized within a one-year period. At March 31, 2021 and December 31, 2020, we had $0 and $4,565, respectively, in marketable securities. Marketable securities are reported at fair value with the related unrealized gains and losses reported as other comprehensive income (loss) until realized or until a determination is made that an other-than-temporary decline in market value has occurred. No significant unrealized gains and losses have been reported during the periods presented. Factors considered by us in assessing whether an other-than-temporary impairment has occurred include the nature of the investment, whether the decline in fair value is attributable to specific adverse conditions affecting the investment, the financial condition of the investee, the severity and the duration of the impairment and whether we have the ability to hold the investment to maturity. When it is determined that an other-than-temporary impairment has occurred, the investment is written down to its market value at the end of the period in which it is determined that an other-than-temporary decline has occurred. The cost of marketable securities sold is based upon the specific identification method. Any realized gains or losses on the sale of investments are reflected as a component of interest income and other expense, net. For the three months ended March 31, 2021, we had no material realized gains or losses from investments in marketable securities classified as available-for-sale. As of December 31, 2020, we had $1 of cumulative unrealized gain, net of tax, which was $0 as of December 31, 2020 due to the full valuation allowance established against our deferred tax assets, in accumulated other comprehensive loss. Segment and geographic information In October 2020, we completed our restructuring activities, which were initiated in December 2019. Prior to the completion of the restructuring activities, we operated as one reportable segment—a service provider of wireless connectivity solutions across our managed and operated network and aggregated network for mobile devices such as laptops, smartphones, tablets and other wireless-enabled consumer devices. This single segment is consistent with the internal organizational structure and the manner in which operations are reviewed and managed by our Chief Executive Officer, the chief operating decision maker. We currently have five reportable and operating segments: (i) carrier services for the provision of wireless and cellular services to our wireless customers (“Carrier Services”); (ii) military for the provision of wireless services on military bases (“Military”); (iii) private networks and emerging technologies for the provision of licensed, unlicensed, and shared spectrum services for our venue partners and non-telecom customers (“Private Networks and Emerging Technologies”); (iv) multifamily for the provision of wireless services for our multifamily property owners (“Multifamily”); and (v) legacy for the provision of our other services such as retail, advertising, and wholesale Wi-Fi services to enterprise customers (“Legacy”). Prior period segment results have been recast to conform to the current presentation. We evaluate reportable and operating segment performance primarily based on revenues and income (loss) from operations, which is our segment operating performance measure. The income (loss) from operations of each reportable and operating segment include only those costs which are specifically related to each reportable and operating segment, which consist primarily of cost of sales, sales and marketing, depreciation, and the direct costs of employees within those reportable and operating segments. We do not allocate corporate overhead costs or non-operating income and expenses to reportable and operating segments, which include unallocable overhead costs associated with our corporate offices, certain executive compensation including stock compensation, costs related to our accounting, finance, legal, engineering, marketing, and human resources departments, among others. Segment information under the new five reportable segment basis, with a reconciliation to the unaudited condensed consolidated statements of operations, is summarized as follows:

​ Assets allocated to each reportable and operating segment include property and equipment, net, goodwill, and intangible assets, net that are specifically identifiable for one of our reportable and operating segments. Our reportable and operating segments also present reporting units for goodwill impairment testing purposes. Unallocated assets are those assets not directly related to a specific reportable and operating segment. There have been no material changes to our assets allocated to each reportable and operating segment from the amount disclosed as of December 31, 2020 as contained in our annual report on Form 10-K filed with the SEC on March 1, 2021, as amended through the Form 10-K/A filed with the SEC on April 28, 2021. All significant long-lived tangible assets are held in the United States of America. We do not disclose sales by geographic area because it would be impracticable to do so. Revenue recognition We generate revenue from several sources including: (i) telecom operators under long-term contracts for access to our DAS, macro tower, small cell, and Wi-Fi networks at our managed and operated locations, (ii) military and retail customers under subscription plans for month-to-month network access that automatically renew, and military and retail single-use access from sales of hourly, daily or other single-use access plans, (iii) arrangements with property owners for multifamily properties that provide for network installation and monthly Wi-Fi services and support for residents and employees or network-as-a-service (“NaaS”), (iv) arrangements with wholesale Wi-Fi customers that provide software licensing, network access, and/or professional services fees, and (v) display advertisements and sponsorships on our walled garden sign-in pages. Software licensed by our wholesale platform services customers can only be used during the term of the service arrangements and has no utility to them upon termination of the service arrangement. Revenues are recognized when a contract with a customer exists and control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services and the identified performance obligation has been satisfied. Contracts entered into at or near the same time with the same customer are combined and accounted for as a single contract if the contracts have a single commercial objective, the amount of consideration is dependent on the price or performance of the other contract, or the services promised in the contracts are a single performance obligation. Contract amendments are routine in the performance of our DAS, tower, small cell, wholesale Wi-Fi, and advertising contracts. Contracts are often amended to account for changes in contract specifications or requirements or expand network access services. In most instances, our DAS, tower, small cell, and wholesale Wi-Fi contract amendments are for additional goods or services that are distinct, and the contract price increases by an amount that reflects the standalone selling price of the additional goods or services; therefore, such contract amendments are accounted for as separate contracts. Contract amendments for our advertising contracts are also generally for additional goods or services that are distinct; however, the contract price does not increase by an amount that reflects the standalone selling price of the additional goods or services. Advertising contract amendments are therefore generally accounted for as contract modifications under the prospective method. Contract amendments to transaction prices with no change in remaining services are accounted for as contract modifications under the cumulative catch-up method. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC 606, Revenue from Contracts with Customers. A contract’s transaction price is allocated to each distinct performance obligation and is recognized as revenue when, or as, the performance obligation is satisfied, which typically occurs when the services are rendered. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. Our contracts with customers may include multiple performance obligations. For such arrangements, we allocate revenue to each performance obligation based on its relative standalone selling price. We generally determine standalone selling prices based on the prices charged to customers. Judgment may be used to determine the standalone selling prices for items that are not sold separately, including services provided at no additional charge. Most of our performance obligations are satisfied over time as services are provided. We generally recognize revenue on a gross basis as we are primarily responsible for fulfilling the promises to provide the specified goods or services, we are responsible for paying all costs related to the goods or services before they have been transferred to the customer, and we have discretion in establishing prices for the specified goods or services. Revenue is presented net of any sales and value added taxes. Payment terms vary on a contract-by-contract basis, although terms generally require payment within 30 to 60 days for non-recurring payments, the first day of the monthly or quarterly billing cycle for recurring payments for DAS, tower, small cell, and wholesale Wi-Fi contracts, and the first day of the month prior to the month that services are provided for Multifamily contracts. We apply a practical expedient for purposes of determining whether a significant financing component may exist for our contracts if, at contract inception, we expect that the period between when we transfer the promised good or service to the customer and when the customer pays for that good or service will be one year or less. In instances where the customer pays for a good or service one year or more in advance of the period when we transfer the promised good or service to the customer, we have determined our contracts generally do not include a significant financing component. The primary purpose of our invoicing terms is not to receive financing from our customers or to provide customers with financing but rather to maximize our profitability on the customer contract. Specifically, inclusion of non-refundable upfront fees in our long-term customer contracts increases the likelihood that the customer will be committed through the end of the contractual term and ensures recoverability of the capital outlay that we incur in expectation of the customer fulfilling its contractual obligations. We may also provide service credits to our customers if we fail to meet contractual monthly system uptime requirements and we account for the variable consideration related to these service credits using the most likely amount method. For contracts that include variable consideration, we estimate the amount of consideration at contract inception under the expected value method or the most likely amount method and include the amount of variable consideration that is not considered to be constrained. Significant judgment is used in constraining estimates of variable consideration. We update our estimates at the end of each reporting period as additional information becomes available. Timing of revenue recognition may differ from the timing of invoicing to customers. We record unbilled receivables (contract assets) when revenue is recognized prior to invoicing, deferred revenue (contract liabilities) when revenue is recognized after invoicing, and receivables when we have an unconditional right to consideration to invoice and receive payment in the future. We present our DAS, Multifamily, and Legacy wholesale Wi-Fi contracts in our condensed consolidated balance sheet as either a contract asset or a contract liability with any unconditional rights to consideration presented separately as a receivable. Our other customer contracts generally do not have any significant contract asset or contract liability balances. Generally, a significant portion of the billing for our DAS contracts occurs prior to revenue recognition, resulting in our DAS contracts being presented as contract liabilities. In contrast, our Legacy wholesale Wi-Fi contracts and Multifamily network-as-a-service (“NaaS”) contracts that contain recurring fees with annual escalations are generally presented as contract assets as revenue is recognized prior to invoicing. Our Multifamily network construction, service and support contracts can be presented as either contract liabilities or contract assets primarily as a result of timing of invoicing for the network installations. We recognize an asset for the incremental costs of obtaining a contract with a customer if we expect the benefit of those costs to be longer than one year. We have determined that certain sales incentive programs meet the requirements to be capitalized. Total capitalized costs to obtain a contract were immaterial during the three months ended March 31, 2021 and are included in prepaid expenses and other current assets and non-current other assets on our condensed consolidated balance sheets. We apply a practical expedient to expense costs as incurred for costs to obtain a contract with a customer when the amortization period would have been one year or less. Contract costs are evaluated for impairment in accordance with ASC 310, Receivables. Carrier services DAS, towers, and small cells We enter into long-term contracts with telecom operators for access to our DAS, tower, and small cell networks at our managed and operated locations. The initial term of our DAS, tower, and small cell contracts with telecom operators can range up to twenty years and the agreements generally contain renewal options. Some of our contracts provide termination for convenience clauses that may or may not include substantive termination penalties. We apply judgment in determining the contract term, the period during which we have present and enforceable rights and obligations. Our DAS, tower, and small cell customer contracts generally contain a single performance obligation—provide non-exclusive access to our DAS, tower, and small cell networks to provide telecom operators’ customers with access to the licensed wireless spectrum, together with providing telecom operators with construction, installation, optimization/engineering, maintenance services and agreed-upon storage space for the telecom operators’ transmission equipment, each related to providing such licensed wireless spectrum to the telecom operators. The performance obligation is considered a series of distinct services as the performance obligation is satisfied over time and the same time-based input method would be used to measure our progress toward complete satisfaction of the performance obligation to transfer each distinct service in the series to the customer. Our contract fee structure generally includes a non-refundable upfront fee and we evaluated whether customer options to renew services give rise to a material right that should be accounted for as a separate performance obligation because of those non-refundable upfront fees. We apply significant judgment in determining whether the customer options to renew services give rise to a material right that should be accounted for as a separate performance obligation. We believe that a material right generally does not exist for our DAS, tower, and small cell customer contracts that contain renewal options because the telecom operators’ decision to renew is highly dependent upon our ability to maintain our exclusivity as the DAS, tower, and small cell service provider at the venue location and our limited operating history with venue and customer renewals. The telecom operators will make the decision to incur the capital improvement costs at the venue location irrespective of our remaining exclusivity period with the venue as the telecom operators expect that the assets will continue to be serviced regardless of whether we will remain such exclusive DAS, tower, and small cell service provider. Our contracts also provide our DAS, tower, and small cell customers with the option to purchase additional future services such as upgrades or enhancements. This option is not considered to provide the customer with a material right that should be accounted for as a separate performance obligation since the cost of the additional future services depends entirely on the market rate of such services at the time such services are requested and we are not automatically obligated to stand ready to deliver these additional goods or services as the customer may reject our proposal. Periodically, we install and sell DAS, tower, and small cell networks to customers where we do not have service contracts or remaining obligations beyond the installation of those networks and we recognize build-out fees for such projects as revenue when the installation work is completed, and the network has been accepted by the customer or using a cost-to-cost method over the network installation period depending on when control is transferred to the customer. Our contract fee structure may include varying components of an upfront build-out fee and recurring access, maintenance, and other fees. The upfront build-out fee is generally structured as a firm-fixed price or cost-plus arrangement and becomes payable as certain contract and/or construction milestones are achieved. Our DAS, tower, and small cell networks are generally neutral-host networks that can accommodate multiple telecom operators. Some of our DAS customer contracts provide for credits that may be issued to existing telecom operators for additional telecom operators subsequently joining the DAS network. The credits are generally based upon a fixed dollar amount per additional telecom operator, a fixed percentage amount of the original build-out fee paid by the telecom operator per additional telecom operator, or a proportionate share based upon the split among the relevant number of telecom operators for the actual costs incurred by all telecom operators to construct the DAS network. In most cases, there is significant uncertainty on whether additional telecom operator contracts will be executed at inception of the contract with the existing telecom operator. We believe that the upfront build-out fee is fixed consideration once the build-out is complete and any subsequent credits that may be issued would be accounted for in a manner similar to a contract modification under the prospective method because (i) the execution of customer contracts with additional telecom carriers is at our sole election and (ii) we would not execute agreements with additional telecom carriers if it would not increase our revenues and gross profits at the venue level. Further, the credits issued to the existing telecom operator changes the transaction price on a go-forward basis, which corresponds with the decline in service levels for the existing telecom operator once the neutral-host DAS network can be accessed by the additional telecom operator. The recurring access, maintenance, and other fees generally escalate on an annual basis. The recurring fees are variable consideration until the contract term and annual escalation dates are fixed. We estimate the variable consideration for our recurring fees using the most likely amount method based on the expected commencement date for the services. We evaluate our estimates of variable consideration each period and record a cumulative catch-up adjustment in the period in which changes occur for the amount allocated to satisfied performance obligations. We generally recognize revenue related to our single performance obligation for our DAS, tower, and small cell customer contracts monthly over the contract term once the customer may access the DAS, tower, and small cell network and we commence maintenance on the DAS, tower, and small cell network. Wi-Fi offload We enter into contracts with telecom operators to move traffic from their licensed cellular networks onto our Wi-Fi networks at our managed and operated locations. Our offload contracts generally contain a single performance obligation—provide non-exclusive rights to access our Wi-Fi networks to provide telecom operators’ end customers with access to the high-speed broadband network that may be bundled together with integration services, support services, and/or performance of standard maintenance. The performance obligation is considered a series of distinct services as the performance obligation is satisfied over time and the same time-based input method or usage-based output method would be used to measure our progress toward complete satisfaction of the performance obligation to transfer each distinct service in the series to the customer. Our contract fee structure includes recurring fees that are accounted for as fixed consideration. We generally recognize revenue related to our single performance obligation for our offload customer contract monthly over the contract term once services have launched. Military Retail Military retail customers must review and agree to abide by our standard “Customer Agreement (With Acceptable Use Policy) and End User License Agreement” before they are able to sign up for our subscription or single-use Wi-Fi network access services. Our Military retail customer contracts generally contain a single performance obligation—provide non-exclusive access to Wi-Fi services, together with performance of standard maintenance, customer support, and the Wi-Finder app to facilitate seamless connection to the Company’s Wi-Fi network. The performance obligation is considered a series of distinct services as the performance obligation is satisfied over time and the same time-based input method would be used to measure our progress toward complete satisfaction of the performance obligation to transfer each distinct service in the series to the customer. Our contracts also provide our Military retail subscription customers with the option to renew the agreement when the subscription term is over. We do not consider this option to provide the customer with a material right that should be accounted for as a separate performance obligation because the customer would not receive a discount if it decided to renew and the option to renew is cancellable within five days’ notice prior to the end of the then current term by either party. The contract transaction price is determined based on the subscription or single-use plan selected by the customer. Our Military retail service plans are for fixed price services as described on our website. From time to time, we offer promotional discounts that result in an immediate reduction in the price paid by the customer. Subscription fees from Military retail customers are paid monthly in advance. We provide refunds for our Military retail services on a case-by-case basis. Refunds and credit card chargeback amounts are not significant and are recorded as contra-revenue in the period the refunds are made, or chargebacks are received. Subscription fee revenue is recognized ratably over the subscription period. Revenue generated from Military retail single-use access is recognized when access is provided, and the performance obligation is satisfied. Bulk services We enter into short-term and long-term contracts with the U.S. government to provide network installation services and Wi-Fi services at specified locations on military bases on a bulk basis. The U.S. government may modify, curtail or terminate its contracts with us, either at its convenience or for default based on performance. Our Military bulk services customer contracts generally contain a single performance obligation—provide non-exclusive rights to access our Wi-Fi networks to provide military personnel with access to the high-speed broadband network that may be bundled together with integration services, support services, and/or performance of standard maintenance. The performance obligation is considered a series of distinct services as the performance obligation is satisfied over time and the same time-based input method would be used to measure our progress toward complete satisfaction of the performance obligation to transfer each distinct service in the series to the customer. Our contract fee structure generally includes a non-refundable upfront fee and we evaluated whether customer options to renew services give rise to a material right that should be accounted for as a separate performance obligation because of those non-refundable upfront fees. We apply significant judgment in determining whether the customer options to renew services give rise to a material right that should be accounted for as a separate performance obligation. We believe that a material right generally exists for our Military bulk services customer contracts that contain renewal options because of our successful history of renewing our contracts with the U.S. government. Our contract fee structure may include varying components of an upfront build-out fee and recurring access fees. The upfront build-out fee is generally structured as a firm-fixed price arrangement and becomes payable as certain contract and/or construction milestones are achieved. The recurring fees may include escalations and are variable consideration until the contract term becomes fixed. We generally recognize revenue related to our single performance obligation for our Military bulk services customer contract monthly on a straight-line basis, where applicable, over the contract term once the customer has accepted the network installation services, where applicable, and services have launched. Private networks and emerging technologies Our customer contracts for private networks and emerging technologies generally contain two performance obligations: (i) install the network required to provide licensed, unlicensed, and shared spectrum services; and (ii) provide management services for those installed networks. Our contracts may also provide our customers with the option to renew the agreement. We do not consider this option to provide the customer with a material right that should be accounted for as a separate performance obligation because the customer would not receive a discount if it decided to renew and the option to renew is generally cancellable by either party subject to the notice of non-renewal requirements specified in the contract. Our contract fee structure generally includes a network installation fee and recurring service fees. The network installation fee is generally structured as a firm-fixed price arrangement and becomes payable as certain contract and/or installation milestones are achieved. Title to the equipment is generally owned by the customer once it is delivered and/or installed. We generally recognize revenue related to our network installation performance obligation using a cost-to-cost method over the network installation period. The recurring fees commence once the network is launched with recurring fees generally based upon a fixed fee that may include annual escalations. We recognize revenue related to the recurring fees on a monthly basis over the contract term as the services are rendered and the performance obligation is satisfied. Multifamily We enter into long-term contracts with property owners for the installation of developer-owned or Boingo-owned Wi-Fi networks and the provisions of recurring Wi-Fi services and technical support once the Wi-Fi networks are constructed. The initial term of our contracts with property owners can range up to ten years and the contracts may contain renewal options. Some of our contracts provide termination for convenience clauses that may or may not include substantive termination penalties. We apply judgment in determining the contract term, which is the period during which we have present and enforceable rights and obligations. Developer-owned networks Our customer contracts for developer-owned Wi-Fi networks that we construct and provide service and support for generally contain two performance obligations: (i) install the network required to provide Wi-Fi services; and (ii) provide Wi-Fi services and technical support to the residents and employees. Our contracts may also provide our property owners with the option to renew the agreement. We do not consider this option to provide the property owner with a material right that should be accounted for as a separate performance obligation because the property owner would not receive a discount if it decided to renew and the option to renew is generally cancellable by either party subject to the notice of non-renewal requirements specified in the contract. Our contracts may also provide our customers with the option to purchase additional future services. We do not consider this option to provide the customer with a material right that should be accounted for as a separate performance obligation since the cost of the additional future services are generally at market rates for such services and we are not automatically obligated to stand ready to deliver these additional goods or services because the customer may reject our proposal. Our contract fee structure generally includes a network installation fee and recurring Wi-Fi service and support fees. The network installation fee is generally structured as a firm-fixed price arrangement and becomes payable as certain contract and/or installation milestones are achieved. We generally estimate variable consideration for unpriced change orders using the most likely amount method based on the expected price for those services. If network installations are not completed by specified dates, we may be subject to network installation penalties. We estimate the variable consideration for our network installation fees using the most likely amount method based on the amount of network installation penalties we expect to incur. Title to the network generally transfers to the property owner once installation is completed and the network has been accepted. We generally recognize revenue related to our network installation performance obligation using a cost-to-cost method over the network installation period. We may provide latent defect warranties for materials and installation labor services related to our network installation services. Our warranty obligations are generally not accounted for as separate performance obligations as warranties cannot be separately purchased and warranties do not provide a service in addition to the assurance that the network will function as expected. The recurring fees commence once the network is launched with recurring fees generally based upon a fixed or variable occupancy rate. The recurring Wi-Fi service fees may be adjusted prospectively for changes in circuit and/or video content costs, and Wi-Fi support fees may escalate on an annual basis. We estimate the variable consideration for our recurring fees using the expected value method with the exception of the variable consideration related to actual occupancy rates, which we record when we have the contractual right to bill. We evaluate our estimates of variable consideration each period and record a cumulative catch-up adjustment in the period in which changes occur for the amount allocated to satisfied performance obligations. We recognize revenue related to the recurring fees on a monthly basis over the contract term as the Wi-Fi services and support is rendered, and the performance obligation is satisfied. Boingo-owned networks / NaaS Our customer contracts for Boingo-owned Wi-Fi networks are generally structured as NaaS arrangements for the provision of Wi-Fi services and technical support for residents and employees at the property as our Boingo-owned Wi-Fi networks may be used by other retail and wholesale Wi-Fi customers. Our NaaS contracts generally contain a single performance obligation—provide non- exclusive rights to access our Wi-Fi networks to provide residents and employees of the property with access to the high-speed broadband network that may be bundled together with technical support services and/or performance of standard network maintenance. The performance obligation is considered a series of distinct services as the performance obligation is satisfied over time and the same time-based input method or usage-based output method would be used to measure our progress toward complete satisfaction of the performance obligation to transfer each distinct service in the series to the customer. Our contract fee structure generally includes recurring fees that generally escalate on an annual basis that are accounted for as fixed considerations. We generally recognize revenue related to our single performance obligation for our NaaS contracts monthly on a straight-line basis, where applicable, over the contract term once services have launched. Legacy Comes with Boingo and Wholesale Wi-Fi We enter into long-term contracts with financial institutions and other enterprise customers who provide access to our Wi-Fi footprint as a value-added service for their customers. We also enter into long-term contracts with enterprise customers such as cable companies, technology companies, and enterprise software/services companies, that pay use usage-based Wi-Fi network access and software licensing fees to allow customers’ access to our footprint worldwide. The initial term of our contracts with Comes with Boingo and wholesale Wi-Fi customers generally range up to five years and the agreements generally contain renewal options. Some of our contracts provide termination for convenience clauses that may or may not include substantive termination penalties. We apply judgment in determining the contract term, the period during which we have present and enforceable rights and obligations. Our Comes with Boingo and wholesale Wi-Fi customer contracts generally contain a single performance obligation—provide non-exclusive rights to access our Wi-Fi networks to provide wholesale Wi-Fi customers' end customers with access to the high-speed broadband network that may be bundled together with integration services, support services, and/or performance of standard maintenance. The performance obligation is considered a series of distinct services as the performance obligation is satisfied over time and the same time-based input method or usage-based output method would be used to measure our progress toward complete satisfaction of the performance obligation to transfer each distinct service in the series to the customer. Our contracts may also provide our enterprise customers with the option to renew the agreement. This option is not considered to provide the customer with a material right that should be accounted for as a separate performance obligation because the customer would not receive a discount if it decided to renew and the option to renew is generally cancellable by either party subject to the notice of non-renewal requirements specified in the contract. Our contracts may also provide our wholesale Wi-Fi customers with the option to purchase additional future services. We do not consider this option to provide the customer with a material right that should be accounted for as a separate performance obligation since the cost of the additional future services are generally at market rates for such services and we are not automatically obligated to stand ready to deliver these additional goods or services because the customer may reject our proposal. Our contract fee structure may include varying components of a minimum fee and usage-based fees. Minimum fees represent fixed price consideration while usage-based fees represent variable consideration. With respect to variable consideration, our commitment to our Comes with Boingo and wholesale Wi-Fi customers consists of providing continuous access to the network. It is therefore a single performance obligation to stand ready to perform and we allocate the variable fees charged for usage when we have the contractual right to bill. The variable component of revenue is recognized based on the actual usage during the period. Comes with Boingo and wholesale Wi-Fi revenue is recognized as it is earned over the relevant contract term with variable consideration recognized when we have the contractual right to bill. Retail Revenue recognition for our Legacy retail customers is the same as for our Military retail customers. Refer to Military retail section for further information. Tenant services We offer our venue partners and their tenants the ability to implement a turnkey Wi-Fi solution through a Wi-Fi networks infrastructure that we install, manage, and operate. Our turnkey solutions for our venue partners include a variety of service models that are supported through a mix of wholesale Wi-Fi, retail, and advertising revenue. Our managed services and tenant services contracts generally contain a single performance obligation—provide non-exclusive rights to access our Wi-Fi networks to provide end customers with access to the high-speed broadband network that may be bundled together with support services and/or performance of standard maintenance. The performance obligation is considered a series of distinct services as the performance obligation is satisfied over time and the same time-based input method or usage-based output method would be used to measure our progress toward complete satisfaction of the performance obligation to transfer each distinct service in the series to the customer. Our contract fee structure may include varying components of an upfront build-out fee and recurring access fees. The upfront build-out fee is generally structured as a firm-fixed price arrangement and becomes payable as certain contract and/or construction milestones are achieved. The recurring fees may include escalations and are variable consideration until the contract term becomes fixed. We generally recognize revenue related to our single performance obligation for our managed services and tenant services customer contract monthly on a straight-line basis, where applicable, over the contract term once the customer has accepted the network installation services, where applicable, and services have launched. Periodically, we install and sell Wi-Fi networks to customers where we do not have service contracts or remaining obligations beyond the installation of those networks, and we recognize build-out fees for such projects as revenue when the installation work is completed, and the network has been accepted by the customer or using a cost-to-cost method over the network installation period depending on when control is transferred to the customer. Advertising We generally enter into short-term cancellable insertion orders with our advertising customers for advertising campaigns that are served at our managed and operated locations and other locations where we solely provide authorized access to a partner’s Wi-Fi network through sponsored and promotional programs. Our sponsorship advertising arrangements are generally priced under a cost per engagement structure, which is a set price per click or engagement, or a cost per install structure for third party application downloads. Our display advertising arrangements are priced based on cost per thousand impressions. Insertion orders may also include bonus items. Our advertising customer contracts may contain multiple performance obligations with each distinct service. These distinct services may include an advertisement video or banner impressions in the contract bundled with the requirement to provide network, space on the website, and integration of customer advertisement onto the website, and each is generally considered to be its own performance obligation. The performance obligations are considered a series of distinct services as the performance obligations are satisfied over time and the same action-based output method would be used to measure our progress toward complete satisfaction of the performance obligation to transfer each distinct service in the series to the customer. The contract transaction price is comprised of variable consideration based on the stated rates applied against the number of units delivered inclusive of the bonus units subject to the maximums provided for in the insertion order. It is customary for us to provide additional units over and above the amounts contractually required; however, there are a number of factors that can also negatively impact our ability to deliver the units required by the customer such as service outages at the venue resulting from power or circuit failures and customer cancellation of the remaining undelivered units under the insertion order due to campaign performance or budgetary constraints. Typically, the advertising campaign periods are short in duration. We therefore use the contractual rates per the insertion orders and actual units delivered to determine the transaction price each period end. The transaction price is allocated to each performance obligation based on the standalone selling price of each performance obligation. Advertising revenue is recognized ratably over the service period based on actual units delivered subject to the maximums provided for in the insertion order. Assets and liabilities held for sale Our Company classifies long-lived assets or disposal groups to be sold as held for sale in the period in which all of the following criteria are met: management, having the authority to approve the action, commits to a plan to sell the asset or disposal group; the asset or disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets or disposal groups; an active program to locate a buyer and other actions required to complete the plan to sell the asset or disposal group have been initiated; the sale of the asset or disposal group is probable, and transfer of the asset or disposal group is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond our control extend the period of time required to sell the asset or disposal group beyond one year; the asset or disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. We initially measure a long-lived asset or disposal group that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held-for-sale criteria are met. Conversely, gains are not recognized on the sale of a long-lived asset or disposal group until the date of sale. We assess the fair value of a long-lived asset or disposal group less any costs to sell each reporting period it remains classified as held-for-sale and report any subsequent changes as an adjustment to the carrying value of the asset or disposal group, as long as the new carrying value does not exceed the carrying value of the asset at the time it was initially classified as held for sale. Upon determining that a long-lived asset or disposal group meets the criteria to be classified as held for sale, the Company ceases depreciation and reports long-lived assets and/or the assets and liabilities of the disposal group, if material, in the line items assets held for sale and liabilities held for sale, respectively, in our condensed consolidated balance sheet. Leases We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets, current portion of operating leases, and long-term portion of operating leases in our condensed consolidated balance sheets. Finance leases are included in property and equipment, net, current portion of finance leases, and long-term portion of finance leases in our condensed consolidated balance sheets. Operating and finance lease right-of-use (“ROU”) assets and ROU 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 for which we are lessee 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. The ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. We have lease agreements with lease and non-lease components, which are accounted for separately for the asset classes maintained. We exclude short-term leases with a lease term of 12 months or less at the commencement date from our condensed consolidated balance sheets. Income taxes We calculate our interim income tax provision in accordance with ASC 270, Interim Reporting, and ASC 740, Accounting for Income Taxes. At the end of each interim period, we estimate the annual effective tax rate and apply that rate to our ordinary quarterly earnings. The tax expense or benefit related to significant, unusual, or extraordinary items is recognized in the interim period in which those items occur. In addition, the effect of changes in enacted tax laws, rates, or tax status is recognized in the interim period in which the change occurs. Excess windfall tax benefits and tax deficiencies related to our stock option exercises and RSU vestings are recognized as an income tax benefit or expense in our condensed consolidated statements of operations in the period they are deducted on the income tax return. Excess windfall tax benefits and tax deficiencies are therefore not anticipated when determining the annual effective tax rate and are instead recognized in the interim period in which those items occur. The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment, including the expected operating income (loss) for the year, projections of the proportion of income (loss) earned and taxed in various states, permanent and temporary differences as a result of differences between amounts measured and recognized in accordance with tax laws and financial accounting standards, and the likelihood of recovering deferred tax assets generated in the current year. The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained, or as the tax environment changes. As of March 31, 2021, we were in a net tested loss position in our subsidiaries located outside of the U.S. In the event that we generate earnings in these subsidiaries, our intention is to indefinitely reinvest these earnings outside the U.S. If we were to remit our foreign earnings, we would be subject to state income taxes or withholding taxes imposed on actual distributions, or currency transaction gains (losses) that would result in taxation upon remittance. However, the amounts of any such tax liabilities resulting from the repatriation of foreign earnings are not material. Foreign currency translation Our Brazilian subsidiary uses the Brazilian Real as its functional currency. Assets and liabilities of our Brazilian subsidiary are translated to U.S. dollars at period-end rates of exchange, and revenues and expenses are translated at average exchange rates prevailing for each month. The resulting translation adjustments are made directly to a separate component of other comprehensive loss, which is reflected in stockholders’ equity in our condensed consolidated balance sheets. As of March 31, 2021 and December 31, 2020, the Company had $(2,742) and $(2,280), respectively, of cumulative foreign currency translation adjustments, net of tax, which was $0 as of March 31, 2021 and December 31, 2020 due to the full valuation allowance established against our deferred tax assets, in accumulated other comprehensive loss. The functional currency for our other foreign subsidiaries is the U.S. dollar. Gains and losses from the revaluation of foreign currency transactions and monetary assets and liabilities are included in the condensed consolidated statements of operations. Use of estimates The preparation of accompanying condensed consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the accompanying condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Assets and liabilities which are subject to significant judgment and the use of estimates include the allowance for doubtful accounts, recoverability of goodwill and long-lived assets, valuation allowances with respect to deferred tax assets, useful lives associated with property and equipment, valuation of ROU assets and ROU liabilities, valuation and useful lives of intangible assets, contract assets and contract liabilities including estimates of variable consideration, and the valuation and assumptions underlying stock-based compensation and other equity instruments. On an ongoing basis, we evaluate our estimates compared to historical experience and trends, which form the basis for making judgments about the carrying value of assets and liabilities. Fair value of financial instruments Fair value is defined as the price that would be received from selling an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, we consider the principal or most advantageous market in which it would transact, and we consider assumptions that market participants would use when pricing the asset or liability. The accounting guidance for fair value measurement also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows:
| ● | Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
| ● | Level 2—Quoted prices for identical assets and liabilities in markets that are not active, quoted prices for similar assets and liabilities in active markets or financial instruments for which significant inputs are observable, either directly or indirectly.
| ● | Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
The carrying amount reflected in the accompanying condensed consolidated balance sheets for cash equivalents, accounts receivable, accounts payable, and accrued expenses and other liabilities approximates fair value due to the short duration and nature of these financial instruments.
