Accounting Policies [Abstract]
Use of Estimates in Preparation of Financial Statements	Use of Estimates in Preparation of Financial Statements The preparation of Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from estimates. Certain reclassifications have been made to prior year Consolidated Financial Statements to conform to current year presentation. The Company evaluates estimates on an ongoing basis.
Principles of Consolidation	Principles of Consolidation The Consolidated Financial Statements include the accounts of Globalstar and all its subsidiaries. All significant intercompany transactions and balances have been eliminated in the consolidation.
Business Combinations	Business Combinations The Company accounts for business combinations in accordance with Accounting Standards Codification ("ASC") Topic 805, Business Combinations (“ASC 805”), which requires most identifiable assets, liabilities, and goodwill acquired in a business combination to be recorded at fair value at the acquisition date. Additionally, ASC 805 requires transaction-related costs to be expensed in the period incurred. The determination of fair value of assets acquired and liabilities assumed requires estimates and assumptions that can change as a result of new information obtained about facts and circumstances that existed as of the acquisition date. As such, the Company will make any necessary adjustments to goodwill in the period identified within one year of the acquisition date. Adjustments outside of that range are recognized currently in earnings.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and highly liquid investments with original maturities of three months or less. Cash deposited in institutional money market funds, regular interest-bearing depository accounts and non-interest-bearing depository accounts are classified as cash and cash equivalents on the accompanying consolidated balance sheets.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents. Cash and cash equivalents consists primarily of highly liquid short-term investments deposited with financial institutions that are of high credit quality. The Company performs credit evaluations of its customers’ financial condition and records reserves to provide for estimated credit losses
Accounts Receivable	Accounts Receivable The Company records trade accounts receivable from its customers, including MSS subscribers and its wholesale capacity customer, when it has a contractual right to receive payment either on demand or on fixed or determinable dates in the future. Receivables are recorded when the right to consideration from the customer becomes unconditional, which is generally upon billing or upon satisfaction of a performance obligation, whichever is earlier. Accounts receivable are uncollateralized, without interest, and consist of receivables from wholesale capacity services and the sale of Globalstar services and equipment. The Company also may act as an agent to procure goods and perform services under the Service Agreements. Payment is generally due within 45 days of the invoice date for this customer. For service, payment is generally due from subscribers within thirty days of the invoice date and for equipment customers, payment is generally due within thirty to sixty days of the invoice date, or, for some customers, may be made in advance of shipment. The Company performs ongoing credit evaluations of its customers and impairs receivable balances by recording specific allowances for credit losses based on factors such as customer credit ratings, supportable and reasonable current trends, the length of time the receivables are past due and historical collection experience. The Company believes that historical collection experience is the most reasonable basis for predicting future performance. One type of the Company’s contract assets is customer receivables and, as such, historical delinquency percentages are generally consistent over time. The estimate of the allowance for subscriber credit losses is computed using aging schedules by type of revenue (service and subscriber equipment), by product (Duplex, SPOT and Commercial IoT) and by country. As discussed above, accounts receivable are considered past due in accordance with the contractual terms of the applicable arrangements. The Company applies a loss rate to its portfolio of subscriber trade receivables based on past-due status and records an allowance for credit losses, which represents the expected losses of those trade receivables over their estimated contractual life. The estimated life may vary by service and product type, but is generally less than one year. Allowances are generally recorded for all aging categories of outstanding receivables, including those in the current category. Accounts receivable balances that are determined likely to be uncollectible are included in the allowance for credit losses. After attempts to collect a receivable have failed, the receivable is written off against the allowance. The estimate of the allowance for credit losses on wholesale capacity receivables is based primarily on customer payment history and credit rating. The Company believes that the risk of loss is extremely remote for this category of outstanding receivables.
Inventory	Inventory Inventory consists primarily of purchased products, including subscriber equipment devices, which work on the Company’s network, as well as component parts and other chips used in the manufacture of subscriber equipment devices. Inventory is stated at the lower of cost or net realizable value. Cost is computed using the first-in, first-out (FIFO) method. Inventory write downs are evaluated at the product level and measured as the difference between the cost of inventory and the net realizable. Write downs are recorded as a cost of subscriber equipment sales - reduction in the value of inventory in the Company’s Consolidated Financial Statements. Product sales and returns from the previous 12 months and future demand forecasts are reviewed and excess and obsolete inventory is written off, as applicable.
Property and Equipment	Property and Equipment The Globalstar System includes costs for the design, manufacture, test and launch of a constellation of low earth orbit satellites (the “Space Component”), primary and backup control centers, gateways (the “Ground Component”) and spectrum licenses. Property and equipment is stated at cost, net of accumulated depreciation. Costs associated with the design, manufacture, test and launch of the Company’s Space and Ground Components are capitalized and include direct costs of third party suppliers and contractors, internal personnel as well as equipment and materials. Capitalized costs associated with the Company’s Space Component, Ground Component, and other assets are tracked by fixed asset category and are allocated to each asset as it comes into service. Generally, when a satellite is incorporated into the constellation, the Company begins depreciation on the date the satellite is placed into service, which was the point that the satellite reaches its orbital altitude, over its estimated depreciable life. In June 2022, the Company launched an on-ground spare satellite. The costs associated with the construction and launch of this spare satellite were placed into service after its successful launch since this satellite is expected to remain as an in-orbit spare and will only be raised to its operational orbit at a future date if needed. The Company capitalizes interest costs associated with the costs of assets in progress. Capitalized interest is added to the cost of the underlying asset and is amortized over the depreciable life of the asset after it is placed into service. As the Company’s construction in progress increases, the Company capitalizes more interest, resulting in a lower amount of net interest expense recognized under U.S. GAAP. Depreciation is provided using the straight-line method over the estimated useful lives of the respective assets as follows: Space Component - 15 years from the commencement of service Ground Component - 7 or 15 years from commencement of service Software, Facilities & Equipment - 3 to 10 years Buildings - 18 years Leasehold Improvements - Shorter of lease term or the estimated useful lives of the improvements The estimated useful lives of the Company's Space and Ground components were based on estimated design life, information from the Company's engineering department and overall Company strategy for the use of these assets. The Company evaluates and revises the estimated depreciable lives assigned to property and equipment based on changes in facts and circumstances. When changes are made to estimated useful lives, the remaining carrying amounts are depreciated prospectively over the remaining useful lives. For assets that are sold or retired, including satellites that are de-orbited and no longer providing services, the estimated cost and accumulated depreciation is removed from property and equipment. The Company assesses the impairment of property and equipment whenever events or changes in circumstances indicate that the recorded value may not be recoverable. Recoverability of assets is measured by comparing the carrying amounts of the assets to the estimated future undiscounted cash flows, excluding financing costs. If the asset is not recoverable, its carrying value would be adjusted down to fair value and an impairment loss would be recorded. Additionally, the Company routinely performs profitability analyses to determine if investments in certain products and/or services remain viable. In the event the Company decides not to support a product or service, or determines that an asset is not expected to generate future benefit, the asset may be abandoned and an impairment loss may be recorded on the associated assets. Assets held for sale are carried at the lower of cost or fair value less estimated cost to sell; these assets are generally classified as current on the Company's consolidated balance sheets as the disposal of these assets is expected within one year.
Leases	Leases The Company has operating and finance leases for facilities and equipment around the world, including corporate offices, satellite control centers, ground control centers, gateways and certain equipment. Upon inception of a contract, the Company evaluates if the contract, or part of the contract, contains a lease. A lease conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Leases include both a right-of-use asset and a lease liability. The right-of-use asset represents the Company’s right to use the underlying asset in the lease. Certain initial direct costs associated with consummating a lease are included in the initial measurement of the right-of-use asset. The right-of-use asset also includes prepaid lease payments and lease incentives. The lease liability represents the present value of the remaining lease payments discounted using the implicit rate in the lease on the lease commencement date. For leases in which the implicit rate is not readily determinable, an estimated incremental borrowing rate is used, which represents a rate of interest that the Company would pay to borrow on a collateralized basis over a similar term. The Company has elected to combine lease and non-lease components, if applicable. For operating leases, the Company records lease expense on a straight-line basis over the lease term in either marketing, general and administrative expense or cost of services, depending on the nature of the underlying asset. For finance leases, the Company records the amortization of the right-of-use asset through depreciation, amortization and accretion expense and records the interest expense on the lease liability through interest expense, net, using the effective interest method. Variable lease payments are payments made to a lessor due to changes in circumstances occurring after the commencement date. Variable lease payments dependent upon an index or rate are included in the measurement of the lease liability; all other variable lease payments are not included in the measurement of the lease liability and recognized when incurred. Variable lease payments excluded from the measurement of the lease liability are uncommon and, when incurred, are immaterial for the Company. The Company’s existing leases have remaining lease terms of less than 1 year to 18 years. Lease terms include renewal or termination options that the Company is reasonably certain to exercise. For leases with a term of twelve months or less, the Company does not record a right-of-use asset and associated lease liability on its consolidated balance sheet. The Company reviews the carrying value of its right-of-use assets for impairment whenever events or changes in circumstances indicate that the recorded value may not be recoverable. Recoverability of assets is measured by comparing the carrying amounts of the assets to the estimated future undiscounted cash flows, excluding financing costs. If a right-of-use asset is not recoverable, its carrying value would be adjusted down to fair value and an impairment loss would be recorded.
Derivative Instruments	Derivative Instruments Upon inception of a contract, the Company evaluates if the contract contains a derivative instrument. The Company has financing arrangements that are hybrid instruments that contain embedded derivative features. Derivative instruments are recognized as either assets or liabilities in the consolidated balance sheets and are measured at fair value with gains or losses recognized in earnings. The Company determines the fair value of derivative instruments based on available market data and assumptions developed by management using appropriate valuation models.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs are those costs directly incurred in issuing long-term debt or equity financing. Costs associated with obtaining long-term debt are amortized as additional interest expense over the expected term of the corresponding instrument and are recorded on the Company's consolidated balance sheets as a reduction in the carrying amount of the related debt liability. The Company classifies deferred financing costs consistent with the classification of the related debt outstanding at the end of the reporting period.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company believes it is not practicable to determine the fair value of its debt agreements on a recurring basis without incurring significant additional costs. Unlike typical long-term debt, certain terms for its debt agreements are not readily available and generally involve a variety of factors, including due diligence by the debt holders. The Company's vendor financing arrangement was recorded at net carrying value, which approximated fair value.
Litigation, Commitments and Contingencies	Litigation, Commitments and Contingencies The Company is subject to various claims and lawsuits that arise in the ordinary course of business. Estimating liabilities and costs associated with these matters requires judgment and assessment based on professional knowledge and experience of our management and legal counsel. When a loss is considered probable and reasonably estimable, a liability is recorded for the Company's best estimate. If there is a range of loss, the Company will record a reserve based on the low end of the range, unless facts and circumstances can support a different point in the range. When a loss is probable, but not reasonably estimable, disclosure is provided, as considered necessary. Reserves for potential claims or lawsuits may be relieved if the loss is no longer considered probable. The ultimate resolution of any such exposure may vary from earlier estimates as further facts and circumstances become known.
Gain/Loss on Extinguishment of Debt	Gain/Loss on Extinguishment of Debt Gain or loss on extinguishment of debt generally is recorded upon an extinguishment of a debt instrument or early payment of debt. Gain or loss on extinguishment of debt is calculated as the difference between the reacquisition price and net carrying amount of the debt, which includes unamortized debt issuance costs and any derivative instruments, and is recorded as an extinguishment gain or loss in the Company’s consolidated statement of operations.
Revenue Recognition and Deferred Revenue	Revenue Recognition and Deferred Revenue Revenue consists primarily of satellite voice and data service revenue, revenue generated from the sale of fixed and mobile devices, revenue generated from providing satellite network access and related services utilizing the Company's satellite spectrum and network of satellite and gateways, and revenue from providing engineering and other communication services. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. Each type of revenue is a separate performance obligation with distinct deliverables and is therefore accounted for discretely. Revenue is measured based on the consideration specified in a contract with a customer, adjusted for credits and discounts, as applicable, and is recognized when the Company satisfies a performance obligation by transferring control over a product or service to a customer. Generally, service revenue is recognized over a period of time and revenue from the sale of subscriber equipment is recognized at a point in time. The recognition of revenue for service is over time as the customer simultaneously receives and consumes the benefits of the Company’s performance over the contract term. The recognition of revenue for subscriber equipment is at a point in time as the risks and rewards of ownership of the hardware transfer to the customer generally upon shipment, which is when legal title of the product transfers to the customer, among other things (as discussed further below). The Company does not record sales taxes, telecommunication taxes or other governmental fees collected from customers in revenue. The Company excludes these taxes from the measurement of contract transaction prices. The Company receives payment from customers in accordance with billing statements or invoices for customer contracts; these payments may be in advance or arrears of services provided to the customer by the Company. Customer payments received in advance of the corresponding service period are recorded as deferred revenue. Upon activation of a Globalstar device, subscribers are generally charged an activation fee, which is recognized over the term of the expected customer life. Credits granted to customers are expensed or charged against revenue or accounts receivable over the remaining term of the contract. Under the Service Agreements, the Company issued warrants to Partner (as defined in Note 3) (the "Warrants") to purchase shares of Globalstar common stock; the Warrants were recorded at the estimated fair value of the consideration granted based on a Black-Scholes pricing model. The fair value of the Warrants was capitalized as a contract asset and is being recognized as a reduction of the transaction price over the estimated term of the Service Agreements. As of December 31, 2023 and 2022, this contract asset was $46.7 million and $52.7 million, respectively, and is netted against the associated contract liability, which is recorded in short-term and long-term deferred revenue on the Company's consolidated balance sheet. The value of the contract asset is amortized as a reduction to revenue over the period in which the Company commences its performance obligations through the estimated completion of the contract term, consistent with the period in which the customer benefits from the services provided. For the year ended December 31, 2023 and 2022, the Company reduced revenue by $2.6 million and $0.2 million, respectively, associated with the amortization of the fair value of the noncash consideration. The Company did not amortize any of the contract asset during 2021. Estimates related to earned but unbilled service revenue are calculated primarily using current subscriber data, including plan subscriptions and usage between the end of the billing cycle and the end of the period, or in accordance with the terms of the customer contract for satellite network access services. The recognition of service revenue related to amounts allocated to performance obligations that were satisfied (or partially satisfied) in a previous period is not material to the Company’s financial statements. Amounts related to earned but unbilled revenue from the sale of subscriber equipment are recognized if hardware is shipped prior to the invoice being generated. This situation may result from multi-deliverable contracts, whereby equipment and service revenue are bundled and billed over time to a single customer. Provisions for estimated future warranty costs, returns and rebates are recorded as a cost of sale, or a reduction to revenue, as applicable. These costs are based on historical trends and the provision is reviewed regularly and periodically adjusted to reflect changes in estimates. Certain contracts with customers may contain a financing component. Under ASC 606, an entity should adjust the promised amount of the consideration for the effects of time value of money if the timing of the payments agreed upon by the parties to the contract provides the customer or the entity with a significant benefit of financing for the transfer of goods or services to the customer. For certain payments associated with services provided under the Service Agreements, the length of time between receipt of payment by the customer and transfer of services by the Company was greater than one year. Accordingly, payments made by this customer included a significant financing component. The Company accreted interest expense using the effective interest rate method over the period in which these advance payments were outstanding. The rate in which interest is computed is based on rates implicit in the Service Agreements. For the Company's subscriber contracts, transactions with a significant financing component are infrequent as the time between cash collection and performance is generally less than one year. The following describes the principal activities from which the Company generates its revenue. Duplex Service Revenue. The Company recognizes revenue for monthly access fees in the period services are rendered. The Company offers certain annual plans whereby a customer prepays for a predetermined amount of minutes and data. In these cases, revenue is recognized consistent with a customer's expected pattern of usage based on historical experience because the Company believes that this method most accurately depicts the satisfaction of the Company's obligation to the customer. This usage pattern is typically seasonal and highest in the second and third calendar quarters of the year. The Company offers other annual plans whereby the customer is charged an annual fee to access the Company’s system with an unlimited amount of usage. Annual fees for unlimited plans are recognized on a straight-line basis over the contract term. SPOT Service Revenue. The Company sells SPOT services as monthly or annual plans and recognizes revenue on a straight-line basis over the service term, beginning when the service is activated by the customer. Commercial IoT Service Revenue. The Company sells Commercial IoT services as monthly or annual plans and recognizes revenue ratably over the service term or as service is used, beginning when the service is activated by the customer. Wholesale Capacity Service Revenue. The Company provides wholesale capacity services. The Company allocates the transaction price under the Service Agreements to each performance obligation generally in proportion to their relative stand-alone selling prices. Revenue is recognized when the performance obligations are performed, the timing of which may involve complex judgements by management. Although the Service Agreements have no expiration date, the Company estimated its contract term based on the useful life of its existing satellite network and the expected useful life of the new satellite network under construction. Equipment Revenue. Equipment revenue represents subscriber device sales, including fixed and mobile user terminals, SPOT and Commercial IoT products, and accessories. The Company recognizes revenue upon shipment provided control has transferred to the customer. Indicators of transfer of control include, but are not limited to; 1) the Company’s right to payment, 2) the customer has legal title of the equipment, 3) the Company has transferred physical possession of the equipment to the customer or carrier, and 4) the customer has significant risks and rewards of ownership of the equipment. The Company sells equipment designed to work on its network through various channels, including through partners as well as direct to consumers or other businesses by its global sales team and through its e-commerce website. The sales channel depends primarily on the type of equipment and geographic region. Promotional rebates are offered from time to time. A reduction to revenue is recorded to reflect the lower transaction price based on an estimate of the customer take rate at the time of the sale using primarily historical data. This estimate is adjusted periodically to reflect actual rebates given to the Company’s customers. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of subscriber equipment sales. Engineering and Other Service Revenue. Other service revenue includes primarily revenue associated with engineering and other communication services using the Company's MSS and terrestrial spectrum licenses. The revenue associated with these engineering services is generally recorded over time as the services are rendered, and the Company's obligation to the customer is satisfied. Multiple-Element Arrangement Contracts. At times, the Company will sell subscriber equipment through multiple-element arrangement contracts with services. When the Company sells subscriber equipment and services in bundled arrangements and determines that it has separate performance obligations, the Company allocates the bundled contract price among the various performance obligations based on relative stand-alone selling prices at contract inception of the distinct goods or services underlying each performance obligation and recognizes revenue when, or as, each performance obligation is satisfied.
Stock-Based Compensation	Stock-Based Compensation The Company recognizes compensation expense in the financial statements for both employee and non-employee share-based awards based on the grant date fair value of those awards and accounts for forfeitures as they occur. The Company uses the Black-Scholes option pricing model to estimate the fair value of stock option awards on the date of grant. For restricted stock awards and units, the fair value is determined from the stock price on the grant date. For existing market-based awards, the fair value was determined using a Monte-Carlo simulation model on the grant date. For share-based awards with a performance condition that affects vesting, the Company recognizes compensation cost for awards if and when the performance condition is probable of achievement. Expense associated with awards with market-based vesting conditions is recognized on a straight-line basis over the requisite service period, which is the lesser of the derived service period or the explicit service period if one is present. If the market condition is satisfied prior to the end of the requisite service period, the Company will accelerate all remaining expense to be recognized.
Foreign Currency	Foreign Currency The functional currency of the Company’s foreign consolidated subsidiaries is generally their local currency, except in certain scenarios, including when the subsidiary operates in a hyperinflationary economy, such as Argentina. Assets and liabilities of its foreign subsidiaries are translated into United States dollars based on exchange rates at the end of the reporting period. Income and expense items are translated at the average exchange rates prevailing during the reporting period. Translation adjustments are accumulated in a separate component of stockholders’ equity.
Asset Retirement Obligation	Asset Retirement Obligation Liabilities arising from legal obligations associated with the retirement of the Company's gateway long-lived assets are measured at fair value and recorded as a liability. Upon initial recognition of a liability for retirement obligations, the Company also capitalizes, as part of the asset carrying amount, the estimated costs associated with its expected retirement. This asset is depreciated over the life of the gateway to be retired. Accretion of the asset retirement obligation liability and depreciation of the related assets are included in depreciation, amortization and accretion in the accompanying consolidated statements of operations.
Warranty Expense	Warranty Expense Warranty terms extend from 90 days on equipment accessories to one year for fixed and mobile user terminals. A provision for estimated future warranty costs is recorded as cost of sales when products are shipped. Warranty costs are based on historical trends in warranty charges as a percentage of gross product shipments.
Research and Development Expenses	Research and Development Expenses Research and development costs were $1.4 million, $0.5 million and $1.0 million for 2023, 2022 and 2021, respectively. The majority of increase in research and development costs are associated with costs incurred pursuant to the SSA under the License Agreement (as defined and discussed further in Note 2: License Agreement). Research and development costs are expensed as incurred as cost of services and include primarily the cost of new product development, chip set design and other engineering work.
Income Taxes	Income Taxes The Company is taxed as a C corporation for U.S. tax purposes. The Company recognizes deferred tax assets and liabilities for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis, operating losses and tax credit carryforwards. The Company measures deferred tax assets and liabilities using tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company recognizes the effect on deferred tax assets and liabilities of a change in tax rates in income in the period that includes the enactment date; however, as the Company has a full valuation allowance on its deferred tax assets, there is no impact to the consolidated statements of operations and balance sheets. The Company recognizes valuation allowances to reduce deferred tax assets to the amount that is more likely than not to be realized. In assessing the likelihood of realization, management considers: (i) future reversals of existing taxable temporary differences; (ii) future taxable income exclusive of reversing temporary differences and carryforwards; (iii) taxable income in prior carry-back year(s) if carry-back is permitted under applicable tax law; and (iv) tax planning strategies.
Comprehensive Income (Loss)	Comprehensive Income (Loss) All components of comprehensive income (loss), including the foreign currency translation adjustment, are reported in the financial statements in the period in which they are recognized. Comprehensive income (loss) is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. For each of the years ended December 31, 2023 and 2022, the change in Accumulated other comprehensive income resulted from foreign currency translation adjustments; no amounts were reclassified out of Accumulated other comprehensive income during these periods.
Earnings (Loss) Per Share	Earnings (Loss) Per Share Basic earnings (loss) per share is computed by dividing income (loss) available to common stockholders by the weighted average number of shares of common stock outstanding during the period. In periods of net income, the numerator used to calculate diluted EPS includes the effect of dilutive securities, including interest expense, net, and derivative gains or losses reflected in net income (loss) as well as the effect of dividends attributable to preferred shareholders. Common stock equivalents are included in the calculation of diluted earnings per share only when the effect of their inclusion would be dilutive. Prior to their conversion, the effect of potentially dilutive common shares for the Company's convertible notes were calculated using the if-converted method. Generally, for all other potentially dilutive common shares, the effect is calculated using the treasury stock method.
Goodwill	Goodwill For acquisitions accounted for as business combinations, goodwill represents the excess of the purchase price over the estimated fair values of identifiable assets and liabilities acquired as of the acquisition date. Goodwill is not amortized in accordance with the requirements of ASC 350. Goodwill is required to be allocated amongst reporting units and evaluated for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment. All of the Company's goodwill is assigned to Globalstar's MSS business, its only reportable segment. Goodwill is tested for impairment on an annual basis on November 30 of each fiscal year and whenever events or circumstances indicate that the asset may be impaired. The Company completed its annual goodwill impairment test on November 30, 2023 and determined there was no impairment as of that date. Additionally, the Company is not aware of any additional triggering events. The Company's goodwill impairment test is prepared using a qualitative assessment, and if necessary, a quantitative goodwill impairment test. The Company considers significant unfavorable industry or economic trends as factors in deciding when to perform an impairment test. If the qualitative assessment indicates that it is more-likely-than-not that the estimated fair value of the reporting unit exceeds its carrying value, it is not necessary to measure and record an impairment loss. If a goodwill impairment test is necessary, the fair value of the reporting unit, which is determined using an income approach based on the present value of discounted cash flows, is compared to its carrying value, which includes goodwill. If the carrying value of the reporting unit exceeds its fair value, the difference is recognized as an impairment loss.
Intangible and Other Assets	Intangible and Other Assets Intangible Assets Not Subject to Amortization A significant portion of the Company's intangible assets are licenses that provide the Company the exclusive right to provide MSS services over the Globalstar System or to utilize designated radio frequency spectrum to provide terrestrial wireless communication services in a particular region of the world. While licenses are issued for only a fixed time, such licenses are subject to renewal by the Federal Communications Commission ("FCC") or equivalent international regulatory authorities. These license renewals are expected to occur routinely and at nominal cost. Moreover, the Company has determined that there are currently no legal, regulatory, contractual, competitive, economic or other factors that limit the useful life of its wireless licenses. As a result, the Company treats the wireless licenses as an indefinite-lived intangible asset. The Company re-evaluates the useful life determination for wireless licenses annually, or more frequently if needed, to determine whether events and circumstances continue to support an indefinite useful life. The Company assesses these intangible assets for impairment annually or more frequently if events or changes in circumstances indicate that it is more likely than not that the asset is impaired. In assessing whether it is more likely than not that such an asset is impaired, the Company assesses relevant events and circumstances that could affect the significant inputs used to determine the fair value of the asset. If the Company determines that an impairment exists, any related loss is estimated based on fair values. Intangible Assets Subject to Amortization Our intangible assets that do not have indefinite lives are amortized over their estimated useful lives. For information related to each major class of intangible assets, including accumulated amortization and estimated average useful lives, see Note 6: Intangible and Other Assets. Intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If an indicator is present, the Company would measure recoverability by comparing the carrying amount to the future undiscounted cash flows the asset is expected to generate. If the asset is not recoverable, the undiscounted cash flows do not exceed the carrying amount and the carrying amount would be adjusted down to its fair value.
Assets Recognized from the Costs to Obtain and Fulfill Contracts	Assets Recognized from the Costs to Obtain and Fulfill Contracts The Company capitalizes incremental costs to obtain and/or fulfill a contract to the extent it expects to recover them. For subscriber-driven contracts, these capitalized contract acquisition costs primarily include deferred subscriber acquisition costs and are amortized consistently with the pattern of transfer of the good or delivery of the service to which the asset relates. For wholesale capacity services, the Company capitalizes costs incurred by the Company prior to the customer benefiting from the service. If a contract terminates prior to the end of its expected life, the remaining capitalized contract costs associated with it becomes impaired and the amount is expensed. For subscriber driven revenue, total contract acquisition costs were $1.2 million and $1.0 million as of December 31, 2023 and 2022, respectively, and are recorded in "Intangible and other assets" on the Company's consolidated balance sheet. These costs are typically amortized to marketing, general and administrative expenses over three years, which considers anticipated contract renewals. For the years ended December 31, 2023, 2022 and 2021, the amount of amortization related to contract acquisition costs was $0.7 million, $1.2 million and $2.1 million, respectively. For wholesale capacity services, total costs to fulfill the customer contract associated with the Service Agreements were $5.7 million and $4.5 million as of December 31, 2023 and 2022, respectively, and are recorded in "Intangible and other assets" on the Company's consolidated balance sheet. These costs are typically amortized to cost of services and marketing, general and administrative expenses over the estimated completion of the contract term, consistent with the period in which the customer benefits from the services provided.
Advertising Expenses	Advertising Expenses Advertising costs were $2.8 million, $2.0 million and $2.3 million for 2023, 2022, and 2021, respectively. These costs are expensed as incurred as marketing, general and administrative expenses.
Recently Issued and Recently Adopted Accounting Pronouncements	Recently Issued Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which provides updates to qualitative and quantitative reportable segment disclosure requirements, including enhanced disclosures about significant segment expenses and increased interim disclosure requirements, among others. This ASU also explicitly requires public entities with a single reportable segment to provide all segment disclosures under ASC 280, including the new disclosures in this ASU. The amendments in ASU 2023-07 are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted, and the amendments should be applied retrospectively. The Company adopted this standard when it became effective on January 1, 2024. The Company is evaluating the impact this ASU may have on its financial statement disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which updates qualitative and quantitative disclosures for the rate reconciliation and income taxes paid. The amendments in ASU 2023-09 are effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied prospectively; however, retrospective application is also permitted. The Company will adopt this standard when it becomes effective on January 1, 2025. The Company is evaluating the impact this ASU may have on its financial statement disclosures. Recently Adopted Accounting Pronouncements In January 2017, the FASB issued ASU No. 2017-04: Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. ASU 2017-04 eliminates the requirement to calculate the implied fair value of goodwill, eliminating Step 2 from the goodwill impairment test. Under ASU 2017-04, goodwill impairment will be tested by comparing the fair value of a reporting unit with its carrying amount, and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. ASU 2017-04 should be applied prospectively and is effective for annual and interim periods beginning after December 15, 2022, with early adoption permitted. Prior to August 2023, the Company did not have any recorded goodwill on its consolidated balance sheets. In connection with the License Agreement (discussed in Note 2: License Agreement) entered into in August 2023, the Company recorded goodwill and is now subject to the guidance pursuant to ASU 2017-04. The Company adopted ASU 2017-04 effective July 1, 2023. The adoption of the new standard did not have a material impact on the Company’s consolidated financial statements. In September 2022, the FASB issued ASU No. 2022-04: Liabilities — Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations. ASU 2022-04 added certain disclosure requirements for buyers in supplier finance programs. The amendments in the update require that buyers disclose qualitative and quantitative information about their supplier finance programs. Interim and annual requirements include disclosure of outstanding amounts under the obligations as of the end of the reporting period, and annual requirements include a rollforward of those obligations for the annual reporting period, as well as a description of payment and other key terms of the programs. This update is effective for annual periods beginning after December 15, 2022, and interim periods within those fiscal years, except for the requirement to disclose rollforward information, which is effective for fiscal years beginning after December 15, 2023. The Company adopted this standard when it became effective on January 1, 2023 and revised its disclosures pursuant ASU 2022-04.
Derivatives, Embedded Derivatives	The fair value of each embedded derivative is marked-to-market at the end of each reporting period, or more frequently as deemed necessary, with any changes in value reported in the consolidated statements of operations and consolidated statements of cash flows as a non-cash operating activity. The instruments and related features embedded in the debt instruments that are required to be accounted for as derivatives are described below.
Fair Value Measurement	The Company follows the authoritative guidance for fair value measurements relating to financial and non-financial assets and liabilities, including presentation of required disclosures herein. This guidance establishes a fair value framework requiring the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets and liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment. The three levels are defined as follows: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities. Level 2: Quoted prices in markets that are not active or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability. Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2023

Use of Estimates in Preparation of Financial Statements

The preparation of Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from estimates. Certain reclassifications have been made to prior year Consolidated Financial Statements to conform to current year presentation. The Company evaluates estimates on an ongoing basis.

Principles of Consolidation

The Consolidated Financial Statements include the accounts of Globalstar and all its subsidiaries. All significant intercompany transactions and balances have been eliminated in the consolidation.

Business Combinations

The Company accounts for business combinations in accordance with Accounting Standards Codification ("ASC") Topic 805, Business Combinations (“ASC 805”), which requires most identifiable assets, liabilities, and goodwill acquired in a business combination to be recorded at fair value at the acquisition date. Additionally, ASC 805 requires transaction-related costs to be expensed in the period incurred. The determination of fair value of assets acquired and liabilities assumed requires estimates and assumptions that can change as a result of new information obtained about facts and circumstances that existed as of the acquisition date. As such, the Company will make any necessary adjustments to goodwill in the period identified within one year of the acquisition date. Adjustments outside of that range are recognized currently in earnings.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash on hand and highly liquid investments with original maturities of three months or less. Cash deposited in institutional money market funds, regular interest-bearing depository accounts and non-interest-bearing depository accounts are classified as cash and cash equivalents on the accompanying consolidated balance sheets.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents. Cash and cash equivalents consists primarily of highly liquid short-term investments deposited with financial institutions that are of high credit quality.

The Company performs credit evaluations of its customers’ financial condition and records reserves to provide for estimated credit losses

Accounts Receivable

The Company records trade accounts receivable from its customers, including MSS subscribers and its wholesale capacity customer, when it has a contractual right to receive payment either on demand or on fixed or determinable dates in the future. Receivables are recorded when the right to consideration from the customer becomes unconditional, which is generally upon billing or upon satisfaction of a performance obligation, whichever is earlier. Accounts receivable are uncollateralized, without interest, and consist of receivables from wholesale capacity services and the sale of Globalstar services and equipment. The Company also may act as an agent to procure goods and perform services under the Service Agreements. Payment is generally due within 45 days of the invoice date for this customer. For service, payment is generally due from subscribers within thirty days of the invoice date and for equipment customers, payment is generally due within thirty to sixty days of the invoice date, or, for some customers, may be made in advance of shipment.

The Company performs ongoing credit evaluations of its customers and impairs receivable balances by recording specific allowances for credit losses based on factors such as customer credit ratings, supportable and reasonable current trends, the length of time the receivables are past due and historical collection experience. The Company believes that historical collection experience is the most reasonable basis for predicting future performance. One type of the Company’s contract assets is customer receivables and, as such, historical delinquency percentages are generally consistent over time. The estimate of the allowance for subscriber credit losses is computed using aging schedules by type of revenue (service and subscriber equipment), by product (Duplex, SPOT and Commercial IoT) and by country. As discussed above, accounts receivable are considered past due in accordance with the contractual terms of the applicable arrangements. The Company applies a loss rate to its portfolio of subscriber trade receivables based on past-due status and records an allowance for credit losses, which represents the expected losses of those trade receivables over their estimated contractual life. The estimated life may vary by service and product type, but is generally less than one year. Allowances are generally recorded for all aging categories of outstanding receivables, including those in the current category. Accounts receivable balances that are determined likely to be uncollectible are included in the allowance for credit losses. After attempts to collect a receivable have failed, the receivable is written off against the allowance. The estimate of the allowance for credit losses on wholesale capacity receivables is based primarily on customer payment history and credit rating. The Company believes that the risk of loss is extremely remote for this category of outstanding receivables.

Inventory

Inventory consists primarily of purchased products, including subscriber equipment devices, which work on the Company’s network, as well as component parts and other chips used in the manufacture of subscriber equipment devices. Inventory is stated at the lower of cost or net realizable value. Cost is computed using the first-in, first-out (FIFO) method. Inventory write downs are evaluated at the product level and measured as the difference between the cost of inventory and the net realizable. Write downs are recorded as a cost of subscriber equipment sales - reduction in the value of inventory in the Company’s Consolidated Financial Statements. Product sales and returns from the previous 12 months and future demand forecasts are reviewed and excess and obsolete inventory is written off, as applicable.

Property and Equipment

The Globalstar System includes costs for the design, manufacture, test and launch of a constellation of low earth orbit satellites (the “Space Component”), primary and backup control centers, gateways (the “Ground Component”) and spectrum licenses. Property and equipment is stated at cost, net of accumulated depreciation.

Costs associated with the design, manufacture, test and launch of the Company’s Space and Ground Components are capitalized and include direct costs of third party suppliers and contractors, internal personnel as well as equipment and materials. Capitalized costs associated with the Company’s Space Component, Ground Component, and other assets are tracked by fixed asset category and are allocated to each asset as it comes into service. Generally, when a satellite is incorporated into the constellation, the Company begins depreciation on the date the satellite is placed into service, which was the point that the satellite reaches its orbital altitude, over its estimated depreciable life. In June 2022, the Company launched an on-ground spare satellite. The costs associated with the construction and launch of this spare satellite were placed into service after its successful launch since this satellite is expected to remain as an in-orbit spare and will only be raised to its operational orbit at a future date if needed.

The Company capitalizes interest costs associated with the costs of assets in progress. Capitalized interest is added to the cost of the underlying asset and is amortized over the depreciable life of the asset after it is placed into service. As the Company’s construction in progress increases, the Company capitalizes more interest, resulting in a lower amount of net interest expense recognized under U.S. GAAP.

Depreciation is provided using the straight-line method over the estimated useful lives of the respective assets as follows:

Space Component - 15 years from the commencement of service

Ground Component - 7 or 15 years from commencement of service

Software, Facilities & Equipment - 3 to 10 years

Buildings - 18 years

Leasehold Improvements - Shorter of lease term or the estimated useful lives of the improvements

The estimated useful lives of the Company's Space and Ground components were based on estimated design life, information from the Company's engineering department and overall Company strategy for the use of these assets. The Company evaluates and revises the estimated depreciable lives assigned to property and equipment based on changes in facts and circumstances. When changes are made to estimated useful lives, the remaining carrying amounts are depreciated prospectively over the remaining useful lives.

For assets that are sold or retired, including satellites that are de-orbited and no longer providing services, the estimated cost and accumulated depreciation is removed from property and equipment.

The Company assesses the impairment of property and equipment whenever events or changes in circumstances indicate that the recorded value may not be recoverable. Recoverability of assets is measured by comparing the carrying amounts of the assets to the estimated future undiscounted cash flows, excluding financing costs. If the asset is not recoverable, its carrying value would be adjusted down to fair value and an impairment loss would be recorded. Additionally, the Company routinely performs profitability analyses to determine if investments in certain products and/or services remain viable. In the event the Company decides not to support a product or service, or determines that an asset is not expected to generate future benefit, the asset may be abandoned and an impairment loss may be recorded on the associated assets.

Assets held for sale are carried at the lower of cost or fair value less estimated cost to sell; these assets are generally classified as current on the Company's consolidated balance sheets as the disposal of these assets is expected within one year.

Leases

The Company has operating and finance leases for facilities and equipment around the world, including corporate offices, satellite control centers, ground control centers, gateways and certain equipment.

Upon inception of a contract, the Company evaluates if the contract, or part of the contract, contains a lease. A lease conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Leases include both a right-of-use asset and a lease liability. The right-of-use asset represents the Company’s right to use the underlying asset in the lease. Certain initial direct costs associated with consummating a lease are included in the initial measurement of the right-of-use asset. The right-of-use asset also includes prepaid lease payments and lease incentives. The lease liability represents the present value of the remaining lease payments discounted using the implicit rate in the lease on the lease commencement date. For leases in which the implicit rate is not readily determinable, an estimated incremental borrowing rate is used, which represents a rate of interest that the Company would pay to borrow on a collateralized basis over a similar term. The Company has elected to combine lease and non-lease components, if applicable.

For operating leases, the Company records lease expense on a straight-line basis over the lease term in either marketing, general and administrative expense or cost of services, depending on the nature of the underlying asset. For finance leases, the Company records the amortization of the right-of-use asset through depreciation, amortization and accretion expense and records the interest expense on the lease liability through interest expense, net, using the effective interest method.

Variable lease payments are payments made to a lessor due to changes in circumstances occurring after the commencement date. Variable lease payments dependent upon an index or rate are included in the measurement of the lease liability; all other variable lease payments are not included in the measurement of the lease liability and recognized when incurred. Variable lease payments excluded from the measurement of the lease liability are uncommon and, when incurred, are immaterial for the Company.

The Company’s existing leases have remaining lease terms of less than 1 year to 18 years. Lease terms include renewal or termination options that the Company is reasonably certain to exercise. For leases with a term of twelve months or less, the Company does not record a right-of-use asset and associated lease liability on its consolidated balance sheet.

The Company reviews the carrying value of its right-of-use assets for impairment whenever events or changes in circumstances indicate that the recorded value may not be recoverable. Recoverability of assets is measured by comparing the carrying amounts of the assets to the estimated future undiscounted cash flows, excluding financing costs. If a right-of-use asset is not recoverable, its carrying value would be adjusted down to fair value and an impairment loss would be recorded.

Derivative Instruments

Upon inception of a contract, the Company evaluates if the contract contains a derivative instrument. The Company has financing arrangements that are hybrid instruments that contain embedded derivative features. Derivative instruments are recognized as either assets or liabilities in the consolidated balance sheets and are measured at fair value with gains or losses recognized in earnings. The Company determines the fair value of derivative instruments based on available market data and assumptions developed by management using appropriate valuation models.

Deferred Financing Costs

Deferred financing costs are those costs directly incurred in issuing long-term debt or equity financing. Costs associated with obtaining long-term debt are amortized as additional interest expense over the expected term of the corresponding instrument and are recorded on the Company's consolidated balance sheets as a reduction in the carrying amount of the related debt liability. The Company classifies deferred financing costs consistent with the classification of the related debt outstanding at the end of the reporting period.

Fair Value of Financial Instruments

The Company believes it is not practicable to determine the fair value of its debt agreements on a recurring basis without incurring significant additional costs. Unlike typical long-term debt, certain terms for its debt agreements are not readily available and generally involve a variety of factors, including due diligence by the debt holders. The Company's vendor financing arrangement was recorded at net carrying value, which approximated fair value.

Litigation, Commitments and Contingencies

The Company is subject to various claims and lawsuits that arise in the ordinary course of business. Estimating liabilities and costs associated with these matters requires judgment and assessment based on professional knowledge and experience of our management and legal counsel. When a loss is considered probable and reasonably estimable, a liability is recorded for the Company's best estimate. If there is a range of loss, the Company will record a reserve based on the low end of the range, unless facts and circumstances can support a different point in the range. When a loss is probable, but not reasonably estimable, disclosure is provided, as considered necessary. Reserves for potential claims or lawsuits may be relieved if the loss is no longer considered probable. The ultimate resolution of any such exposure may vary from earlier estimates as further facts and circumstances become known.

Gain/Loss on Extinguishment of Debt

Gain or loss on extinguishment of debt generally is recorded upon an extinguishment of a debt instrument or early payment of debt. Gain or loss on extinguishment of debt is calculated as the difference between the reacquisition price and net carrying amount of the debt, which includes unamortized debt issuance costs and any derivative instruments, and is recorded as an extinguishment gain or loss in the Company’s consolidated statement of operations.

Revenue Recognition and Deferred Revenue

Revenue consists primarily of satellite voice and data service revenue, revenue generated from the sale of fixed and mobile devices, revenue generated from providing satellite network access and related services utilizing the Company's satellite spectrum and network of satellite and gateways, and revenue from providing engineering and other communication services. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. Each type of revenue is a separate performance obligation with distinct deliverables and is therefore accounted for discretely. Revenue is measured based on the consideration specified in a contract with a customer, adjusted for credits and discounts, as applicable, and is recognized when the Company satisfies a performance obligation by transferring control over a product or service to a customer.

Generally, service revenue is recognized over a period of time and revenue from the sale of subscriber equipment is recognized at a point in time. The recognition of revenue for service is over time as the customer simultaneously receives and consumes the benefits of the Company’s performance over the contract term. The recognition of revenue for subscriber

equipment is at a point in time as the risks and rewards of ownership of the hardware transfer to the customer generally upon shipment, which is when legal title of the product transfers to the customer, among other things (as discussed further below).

The Company does not record sales taxes, telecommunication taxes or other governmental fees collected from customers in revenue. The Company excludes these taxes from the measurement of contract transaction prices.

The Company receives payment from customers in accordance with billing statements or invoices for customer contracts; these payments may be in advance or arrears of services provided to the customer by the Company. Customer payments received in advance of the corresponding service period are recorded as deferred revenue.

Upon activation of a Globalstar device, subscribers are generally charged an activation fee, which is recognized over the term of the expected customer life. Credits granted to customers are expensed or charged against revenue or accounts receivable over the remaining term of the contract.

Under the Service Agreements, the Company issued warrants to Partner (as defined in Note 3) (the "Warrants") to purchase shares of Globalstar common stock; the Warrants were recorded at the estimated fair value of the consideration granted based on a Black-Scholes pricing model. The fair value of the Warrants was capitalized as a contract asset and is being recognized as a reduction of the transaction price over the estimated term of the Service Agreements. As of December 31, 2023 and 2022, this contract asset was $46.7 million and $52.7 million, respectively, and is netted against the associated contract liability, which is recorded in short-term and long-term deferred revenue on the Company's consolidated balance sheet. The value of the contract asset is amortized as a reduction to revenue over the period in which the Company commences its performance obligations through the estimated completion of the contract term, consistent with the period in which the customer benefits from the services provided. For the year ended December 31, 2023 and 2022, the Company reduced revenue by $2.6 million and $0.2 million, respectively, associated with the amortization of the fair value of the noncash consideration. The Company did not amortize any of the contract asset during 2021.

Estimates related to earned but unbilled service revenue are calculated primarily using current subscriber data, including plan subscriptions and usage between the end of the billing cycle and the end of the period, or in accordance with the terms of the customer contract for satellite network access services. The recognition of service revenue related to amounts allocated to performance obligations that were satisfied (or partially satisfied) in a previous period is not material to the Company’s financial statements. Amounts related to earned but unbilled revenue from the sale of subscriber equipment are recognized if hardware is shipped prior to the invoice being generated. This situation may result from multi-deliverable contracts, whereby equipment and service revenue are bundled and billed over time to a single customer.

Provisions for estimated future warranty costs, returns and rebates are recorded as a cost of sale, or a reduction to revenue, as applicable. These costs are based on historical trends and the provision is reviewed regularly and periodically adjusted to reflect changes in estimates.

Certain contracts with customers may contain a financing component. Under ASC 606, an entity should adjust the promised amount of the consideration for the effects of time value of money if the timing of the payments agreed upon by the parties to the contract provides the customer or the entity with a significant benefit of financing for the transfer of goods or services to the customer. For certain payments associated with services provided under the Service Agreements, the length of time between receipt of payment by the customer and transfer of services by the Company was greater than one year. Accordingly, payments made by this customer included a significant financing component. The Company accreted interest expense using the effective interest rate method over the period in which these advance payments were outstanding. The rate in which interest is computed is based on rates implicit in the Service Agreements. For the Company's subscriber contracts, transactions with a significant financing component are infrequent as the time between cash collection and performance is generally less than one year.

The following describes the principal activities from which the Company generates its revenue.

Duplex Service Revenue. The Company recognizes revenue for monthly access fees in the period services are rendered. The Company offers certain annual plans whereby a customer prepays for a predetermined amount of minutes and data. In these cases, revenue is recognized consistent with a customer's expected pattern of usage based on historical experience because the Company believes that this method most accurately depicts the satisfaction of the Company's obligation to the customer. This usage pattern is typically seasonal and highest in the second and third calendar quarters of the year. The Company offers other annual plans whereby the customer is charged an annual fee to access the Company’s system with an unlimited amount of usage. Annual fees for unlimited plans are recognized on a straight-line basis over the contract term.

SPOT Service Revenue. The Company sells SPOT services as monthly or annual plans and recognizes revenue on a straight-line basis over the service term, beginning when the service is activated by the customer.

Commercial IoT Service Revenue. The Company sells Commercial IoT services as monthly or annual plans and recognizes revenue ratably over the service term or as service is used, beginning when the service is activated by the customer.

Wholesale Capacity Service Revenue. The Company provides wholesale capacity services. The Company allocates the transaction price under the Service Agreements to each performance obligation generally in proportion to their relative stand-alone selling prices. Revenue is recognized when the performance obligations are performed, the timing of which may involve complex judgements by management. Although the Service Agreements have no expiration date, the Company estimated its contract term based on the useful life of its existing satellite network and the expected useful life of the new satellite network under construction.

Equipment Revenue. Equipment revenue represents subscriber device sales, including fixed and mobile user terminals, SPOT and Commercial IoT products, and accessories. The Company recognizes revenue upon shipment provided control has transferred to the customer. Indicators of transfer of control include, but are not limited to; 1) the Company’s right to payment, 2) the customer has legal title of the equipment, 3) the Company has transferred physical possession of the equipment to the customer or carrier, and 4) the customer has significant risks and rewards of ownership of the equipment. The Company sells equipment designed to work on its network through various channels, including through partners as well as direct to consumers or other businesses by its global sales team and through its e-commerce website. The sales channel depends primarily on the type of equipment and geographic region. Promotional rebates are offered from time to time. A reduction to revenue is recorded to reflect the lower transaction price based on an estimate of the customer take rate at the time of the sale using primarily historical data. This estimate is adjusted periodically to reflect actual rebates given to the Company’s customers. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of subscriber equipment sales.

Engineering and Other Service Revenue. Other service revenue includes primarily revenue associated with engineering and other communication services using the Company's MSS and terrestrial spectrum licenses. The revenue associated with these engineering services is generally recorded over time as the services are rendered, and the Company's obligation to the customer is satisfied.

Multiple-Element Arrangement Contracts. At times, the Company will sell subscriber equipment through multiple-element arrangement contracts with services. When the Company sells subscriber equipment and services in bundled arrangements and determines that it has separate performance obligations, the Company allocates the bundled contract price among the various performance obligations based on relative stand-alone selling prices at contract inception of the distinct goods or services underlying each performance obligation and recognizes revenue when, or as, each performance obligation is satisfied.

Stock-Based Compensation

The Company recognizes compensation expense in the financial statements for both employee and non-employee share-based awards based on the grant date fair value of those awards and accounts for forfeitures as they occur. The Company uses the Black-Scholes option pricing model to estimate the fair value of stock option awards on the date of grant. For restricted stock awards and units, the fair value is determined from the stock price on the grant date. For existing market-based awards, the fair value was determined using a Monte-Carlo simulation model on the grant date.

For share-based awards with a performance condition that affects vesting, the Company recognizes compensation cost for awards if and when the performance condition is probable of achievement. Expense associated with awards with market-based vesting conditions is recognized on a straight-line basis over the requisite service period, which is the lesser of the derived service period or the explicit service period if one is present. If the market condition is satisfied prior to the end of the requisite service period, the Company will accelerate all remaining expense to be recognized.

Foreign Currency

The functional currency of the Company’s foreign consolidated subsidiaries is generally their local currency, except in certain scenarios, including when the subsidiary operates in a hyperinflationary economy, such as Argentina. Assets and liabilities of its foreign subsidiaries are translated into United States dollars based on exchange rates at the end of the reporting period. Income and expense items are translated at the average exchange rates prevailing during the reporting period. Translation adjustments are accumulated in a separate component of stockholders’ equity.

Asset Retirement Obligation

Liabilities arising from legal obligations associated with the retirement of the Company's gateway long-lived assets are measured at fair value and recorded as a liability. Upon initial recognition of a liability for retirement obligations, the Company also capitalizes, as part of the asset carrying amount, the estimated costs associated with its expected retirement. This asset is depreciated over the life of the gateway to be retired. Accretion of the asset retirement obligation liability and depreciation of the related assets are included in depreciation, amortization and accretion in the accompanying consolidated statements of operations.

Warranty Expense

Warranty terms extend from 90 days on equipment accessories to one year for fixed and mobile user terminals. A provision for estimated future warranty costs is recorded as cost of sales when products are shipped. Warranty costs are based on historical trends in warranty charges as a percentage of gross product shipments.

Research and Development Expenses

Research and development costs were $1.4 million, $0.5 million and $1.0 million for 2023, 2022 and 2021, respectively. The majority of increase in research and development costs are associated with costs incurred pursuant to the SSA under the License Agreement (as defined and discussed further in Note 2: License Agreement). Research and development costs are expensed as incurred as cost of services and include primarily the cost of new product development, chip set design and other engineering work.

Income Taxes

The Company is taxed as a C corporation for U.S. tax purposes. The Company recognizes deferred tax assets and liabilities for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis, operating losses and tax credit carryforwards. The Company measures deferred tax assets and liabilities using tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company recognizes the effect on deferred tax assets and liabilities of a change in tax rates in income in the period that includes the enactment date; however, as the Company has a full valuation allowance on its deferred tax assets, there is no impact to the consolidated statements of operations and balance sheets.

The Company recognizes valuation allowances to reduce deferred tax assets to the amount that is more likely than not to be realized. In assessing the likelihood of realization, management considers: (i) future reversals of existing taxable temporary differences; (ii) future taxable income exclusive of reversing temporary differences and carryforwards; (iii) taxable income in prior carry-back year(s) if carry-back is permitted under applicable tax law; and (iv) tax planning strategies.

Comprehensive Income (Loss)

All components of comprehensive income (loss), including the foreign currency translation adjustment, are reported in the financial statements in the period in which they are recognized. Comprehensive income (loss) is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. For each of the years ended December 31, 2023 and 2022, the change in Accumulated other comprehensive income resulted from foreign currency translation adjustments; no amounts were reclassified out of Accumulated other comprehensive income during these periods.

Earnings (Loss) Per Share

Basic earnings (loss) per share is computed by dividing income (loss) available to common stockholders by the weighted average number of shares of common stock outstanding during the period. In periods of net income, the numerator used to calculate diluted EPS includes the effect of dilutive securities, including interest expense, net, and derivative gains or losses reflected in net income (loss) as well as the effect of dividends attributable to preferred shareholders. Common stock equivalents are included in the calculation of diluted earnings per share only when the effect of their inclusion would be dilutive. Prior to their conversion, the effect of potentially dilutive common shares for the Company's convertible notes were calculated using the if-converted method. Generally, for all other potentially dilutive common shares, the effect is calculated using the treasury stock method.

Goodwill

For acquisitions accounted for as business combinations, goodwill represents the excess of the purchase price over the estimated fair values of identifiable assets and liabilities acquired as of the acquisition date. Goodwill is not amortized in accordance with the requirements of ASC 350. Goodwill is required to be allocated amongst reporting units and evaluated for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment. All of the Company's goodwill is assigned to Globalstar's MSS business, its only reportable segment.

Goodwill is tested for impairment on an annual basis on November 30 of each fiscal year and whenever events or circumstances indicate that the asset may be impaired. The Company completed its annual goodwill impairment test on November 30, 2023 and determined there was no impairment as of that date. Additionally, the Company is not aware of any additional triggering events. The Company's goodwill impairment test is prepared using a qualitative assessment, and if necessary, a quantitative goodwill impairment test. The Company considers significant unfavorable industry or economic trends as factors in deciding when to perform an impairment test. If the qualitative assessment indicates that it is more-likely-than-not that the estimated fair value of the reporting unit exceeds its carrying value, it is not necessary to measure and record an impairment loss. If a goodwill impairment test is necessary, the fair value of the reporting unit, which is determined using an income approach based on the present value of discounted cash flows, is compared to its carrying value, which includes goodwill. If the carrying value of the reporting unit exceeds its fair value, the difference is recognized as an impairment loss.

Intangible and Other Assets

Intangible Assets Not Subject to Amortization

A significant portion of the Company's intangible assets are licenses that provide the Company the exclusive right to provide MSS services over the Globalstar System or to utilize designated radio frequency spectrum to provide terrestrial wireless communication services in a particular region of the world. While licenses are issued for only a fixed time, such licenses are subject to renewal by the Federal Communications Commission ("FCC") or equivalent international regulatory authorities. These license renewals are expected to occur routinely and at nominal cost. Moreover, the Company has determined that there are currently no legal, regulatory, contractual, competitive, economic or other factors that limit the useful life of its wireless licenses. As a result, the Company treats the wireless licenses as an indefinite-lived intangible asset. The Company re-evaluates the useful life determination for wireless licenses annually, or more frequently if needed, to determine whether events and circumstances continue to support an indefinite useful life. The Company assesses these intangible assets for impairment annually or more frequently if events or changes in circumstances indicate that it is more likely than not that the asset is impaired. In assessing whether it is more likely than not that such an asset is impaired, the Company assesses relevant events and circumstances that could affect the significant inputs used to determine the fair value of the asset. If the Company determines that an impairment exists, any related loss is estimated based on fair values.

Intangible Assets Subject to Amortization

Our intangible assets that do not have indefinite lives are amortized over their estimated useful lives. For information related to each major class of intangible assets, including accumulated amortization and estimated average useful lives, see Note 6: Intangible and Other Assets. Intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If an indicator is present, the Company would measure recoverability by comparing the carrying amount to the future undiscounted cash flows the asset is expected to generate. If the asset is not recoverable, the undiscounted cash flows do not exceed the carrying amount and the carrying amount would be adjusted down to its fair value.

Assets Recognized from the Costs to Obtain and Fulfill Contracts

The Company capitalizes incremental costs to obtain and/or fulfill a contract to the extent it expects to recover them. For subscriber-driven contracts, these capitalized contract acquisition costs primarily include deferred subscriber acquisition costs and are amortized consistently with the pattern of transfer of the good or delivery of the service to which the asset relates. For wholesale capacity services, the Company capitalizes costs incurred by the Company prior to the customer benefiting from the service. If a contract terminates prior to the end of its expected life, the remaining capitalized contract costs associated with it becomes impaired and the amount is expensed.

Recently Issued and Recently Adopted Accounting Pronouncements

Recently Issued Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which provides updates to qualitative and quantitative reportable segment disclosure requirements, including enhanced disclosures about significant segment expenses and increased interim disclosure requirements, among others. This ASU also explicitly requires public entities with a single reportable segment to provide all segment disclosures under ASC 280, including the new disclosures in this ASU. The amendments in ASU 2023-07 are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted, and the amendments should be applied retrospectively. The Company adopted this standard when it became effective on January 1, 2024. The Company is evaluating the impact this ASU may have on its financial statement disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which updates qualitative and quantitative disclosures for the rate reconciliation and income taxes paid. The amendments in ASU 2023-09 are effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied prospectively; however, retrospective application is also permitted. The Company will adopt this standard when it becomes effective on January 1, 2025. The Company is evaluating the impact this ASU may have on its financial statement disclosures.

Recently Adopted Accounting Pronouncements

In January 2017, the FASB issued ASU No. 2017-04: Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. ASU 2017-04 eliminates the requirement to calculate the implied fair value of goodwill, eliminating Step 2 from the goodwill impairment test. Under ASU 2017-04, goodwill impairment will be tested by comparing the fair value of a reporting unit with its carrying amount, and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. ASU 2017-04 should be applied prospectively and is effective for annual and interim periods beginning after December 15, 2022, with early adoption permitted. Prior to August 2023, the Company did not have any recorded goodwill on its consolidated balance sheets. In connection with the License Agreement (discussed in Note 2: License Agreement) entered into in August 2023, the Company recorded goodwill and is now subject to the guidance pursuant to ASU 2017-04. The Company adopted ASU 2017-04 effective July 1, 2023. The adoption of the new standard did not have a material impact on the Company’s consolidated financial statements.

In September 2022, the FASB issued ASU No. 2022-04: Liabilities — Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations. ASU 2022-04 added certain disclosure requirements for buyers in supplier finance programs. The amendments in the update require that buyers disclose qualitative and quantitative information about their supplier finance programs. Interim and annual requirements include disclosure of outstanding amounts under the obligations as of the end of the reporting period, and annual requirements include a rollforward of those obligations for the annual reporting period, as well as a description of payment and other key terms of the programs. This update is effective for annual periods beginning after December 15, 2022, and interim periods within those fiscal years, except for the requirement to disclose rollforward information, which is effective for fiscal years beginning after December 15, 2023. The Company adopted this standard when it became effective on January 1, 2023 and revised its disclosures pursuant ASU 2022-04.

Derivatives, Embedded Derivatives

The fair value of each embedded derivative is marked-to-market at the end of each reporting period, or more frequently as deemed necessary, with any changes in value reported in the consolidated statements of operations and consolidated statements of cash flows as a non-cash operating activity. The instruments and related features embedded in the debt instruments that are required to be accounted for as derivatives are described below.

Fair Value Measurement

The Company follows the authoritative guidance for fair value measurements relating to financial and non-financial assets and liabilities, including presentation of required disclosures herein. This guidance establishes a fair value framework requiring the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets and liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment. The three levels are defined as follows:

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities.

Level 2: Quoted prices in markets that are not active or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability.

Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).
