Organization and Business Activities	ORGANIZATION AND BUSINESS ACTIVITIES Principal Business Hughes Satellite Systems Corporation (which, together with its subsidiaries, is referred to as “HSS,” the “Company,” “we,” “us” and/or “our”) is a holding company and a subsidiary of EchoStar Corporation (“EchoStar”). We are a global provider of broadband satellite technologies, broadband internet services for home and small office customers, satellite operations and satellite services. We also deliver innovative network technologies, managed services and various communications solutions for aeronautical, enterprise and government customers. We primarily operate in the following two business segments: • Hughes — which provides broadband satellite technologies and broadband internet services to domestic and international home and small office customers and broadband network technologies, managed services, equipment, hardware, satellite services and communication solutions to domestic and international consumers and aeronautical, enterprise and government customers. The Hughes segment also designs, provides and installs gateway and terminal equipment to customers for other satellite systems. In addition, our Hughes segment designs, develops, constructs and provides telecommunication networks comprising satellite ground segment systems and terminals to mobile system operators and our enterprise customers. • EchoStar Satellite Services (“ESS”) — which uses certain of our owned and leased in-orbit satellites and related licenses to provide satellite operations and satellite services on a full-time and/or occasional-use basis primarily to DISH Network Corporation and its subsidiaries (“DISH Network”), Dish Mexico, S. de R.L. de C.V., a joint venture that EchoStar entered into in 2008 (“Dish Mexico”), United States (“U.S.”) government service providers, internet service providers, broadcast news organizations, content providers, and private enterprise customers. Our operations also include various corporate departments (primarily Executive, Treasury, Strategic Development, Human Resources, IT, Finance, Real Estate, Accounting and Legal) and other activities that have not been assigned to our operating segments such as costs incurred in certain satellite development programs and other business development activities, and gains or losses from certain of our investments. These activities, costs and income, as well as eliminations of intersegment transactions, are accounted for in Corporate and Other in our segment reporting. During 2017, EchoStar and certain of its and our subsidiaries entered into a share exchange agreement with DISH and certain of its subsidiaries. EchoStar, and certain of its and our subsidiaries, received all of the shares of the Hughes Retail Preferred Tracking Stock previously issued by EchoStar and us (together, the “Tracking Stock”) in exchange for 100% of the equity interests of certain of EchoStar subsidiaries that held substantially all of EchoStar’s former EchoStar Technologies businesses and certain other assets (collectively, the “Share Exchange”).

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation and Basis of Presentation We consolidate all entities in which we have a controlling financial interest. We are deemed to have a controlling financial interest in variable interest entities where we are the primary beneficiary. We are deemed to have a controlling financial interest in other entities when we own more than 50% of the outstanding voting shares and other shareholders do not have substantive rights to participate in management. For entities we control but do not wholly own, we record a noncontrolling interest within shareholders’ equity for the portion of the entity’s equity attributed to the noncontrolling ownership interests. All significant intercompany balances and transactions have been eliminated in consolidation. Reclassification Certain prior period amounts have been reclassified to conform with the current period presentation. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the U.S. (“GAAP”) requires us to make certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the balance sheets, the reported amounts of revenue and expense for each reporting period and certain information disclosed in the notes to our financial statements. Estimates are used in accounting for, among other things, (i) amortization periods for deferred contract acquisition costs, (ii) inputs used to recognize revenue over time, (iii) allowances for doubtful accounts, (iv) warranty obligations, (v) self-insurance obligations, (vi) deferred taxes and related valuation allowances, (vii) uncertain tax positions, (viii) loss contingencies, (ix) fair value of financial instruments, (x) fair value of EchoStar’s stock-based compensation awards, (xi) fair value of assets and liabilities acquired in business combinations, (xii) lease classifications, (xiii) asset impairment testing and (xiv) useful lives and methods for depreciation and amortization of long-lived assets. We base our estimates and assumptions on historical experience, observable market inputs and on various other factors that we believe to be relevant under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results may differ from previously estimated amounts, and such differences may be material to our financial statements. Additionally, changing economic conditions may increase the inherent uncertainty in the estimates and assumptions indicated above. We review our estimates and assumptions periodically and the effects of revisions thereto are reflected in the period they occur or prospectively if the revised estimate affects future periods. Fair Value Measurements We determine fair value based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. Market or observable inputs are the preferred source of values, followed by unobservable inputs or assumptions based on hypothetical transactions in the absence of market inputs. We utilize the highest level of inputs available according to the following hierarchy in determining fair value • Level 1 - Defined as observable inputs being quoted prices in active markets for identical assets; • Level 2 - Defined as observable inputs other than quoted prices included in Level 1, including quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and • Level 3 - Defined as unobservable inputs for which little or no market data exists, consistent with characteristics of the asset or liability that would be considered by market participants in a transaction to purchase or sell the asset or liability. Fair values of our marketable investment securities are based on a variety of observable market inputs. For our investments in publicly traded equity securities and U.S. government securities, fair value ordinarily is determined based on Level 1 measurements that reflect quoted prices for identical securities in active markets. Fair values of our investments in other marketable debt securities are generally based on Level 2 measurements, as the markets for such debt securities are less active. We consider trades of identical debt securities on or near the measurement date as a strong indication of fair value and matrix pricing techniques that consider par value, coupon rate, credit quality, maturity and other relevant features may also be used to determine fair value of our investments in marketable debt securities. Fair values for our outstanding debt (see Note 10 ) are based on quoted market prices in less active markets and are categorized as Level 2 measurements. Additionally, we use fair value measurements from time to time in connection with asset impairment testing and the assignment of purchase consideration to assets and liabilities of acquired companies. Those fair value measurements typically include significant unobservable inputs and are categorized within Level 3 of the fair value hierarchy. Transfers between levels in the fair value hierarchy are considered to occur at the beginning of the quarterly accounting period. There were no transfers between levels for each of the years ended December 31, 2018 and 2017 . As of December 31, 2018 and 2017 , the carrying amounts of our cash and cash equivalents, trade and other receivables, net of allowance for doubtful accounts, accounts payable and accrued liabilities were equal to or approximated their fair value due to their short-term nature or proximity to current market rates. Revenue Recognition Overview We account for our sales and services revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“Topic 606”) , which we adopted on January 1, 2018, using the modified retrospective approach to contracts not completed as of the adoption date. Topic 606 provides a five-step revenue recognition model that we apply to our customer contracts. Under this model we (i) identify the contract with the customer, (ii) identify our performance obligations in the contract, (iii) determine the transaction price for the contract, (iv) allocate the transaction price to our performance obligations and (v) recognize revenue when or as we satisfy our performance obligations. Revenue is recognized upon transfer of control of the promised goods or our performance of the services to our customers in an amount that reflects the consideration we expect to receive in exchange for those goods or services. We enter into contracts that may include various combinations of products and services, which are generally distinct and accounted for as separate performance obligations. Additionally, a significant portion of our revenue is derived from leases of property and equipment that is reported in Services and other revenue - other and Services and other revenue - DISH Network in our Consolidated Statements of Operations and Comprehensive Income (Loss). Certain of our customer contracts contain embedded equipment leases, which we separate from non-lease components of the contract based on the relative standalone selling prices of the lease and non-lease components. Hughes Our Hughes segment provides various communication and networking services to consumer and enterprise customers in both domestic and international markets. Our service contracts typically obligate us to provide substantially the same services on a recurring basis in exchange for fixed recurring fees over the term of the contract. We satisfy such performance obligations over time and recognize revenue ratably as services are rendered over the service period. Certain of our contracts with service obligations provide for fees based on usage, capacity or volume. We satisfy these performance obligations and recognize the related revenue at the point in time or over the period when the services are rendered. Our Hughes segment also sells and leases communications equipment to its customers. Revenue from equipment sales generally is recognized upon shipment of the equipment. Our equipment sales contracts typically include standard product warranties, but generally do not provide for returns or refunds. Revenue for extended warranties is recognized ratably over the extended warranty period. For contracts with multiple performance obligations, we typically allocate the contract’s transaction price to each performance obligation based on their relative standalone selling prices. When the standalone selling price is not observable, our primary method used to estimate standalone selling price is the expected cost plus a margin. Our contracts generally require customer payments to be made at or shortly after the time we transfer control of goods or perform the services. In addition to equipment and service offerings, our Hughes segment also enters into long-term contracts to design, develop, construct and install complex telecommunication networks to customers in its enterprise and mobile satellite systems markets. Revenue from such contracts is generally recognized over time at a measure of progress that depicts the transfer of control of the goods or services to the customer. Depending on the nature of the arrangement, we measure progress toward contract completion using an appropriate input method or output method. Under the input method, we recognize the transaction price as revenue based on the ratio of costs incurred to estimated total costs at completion. Under the output method, revenue and cost of sales are recognized as products are delivered based on the expected profit for the entire agreement. Profit margins on long-term contracts generally are based on estimates of revenue and costs at completion. We review and revise our estimates periodically and recognize related adjustments in the period in which the revisions are made. Estimated losses on contracts are recorded in the period in which they are identified. We generally receive interim payments as work progresses, although for some contracts, we may be entitled to receive an advance payment. ESS Our ESS segment provides satellite operations through leasing arrangements and satellite services on a full-time and/or occasional-use basis to DISH Network and Dish Mexico, as well as government service providers, internet service providers, broadcast news organizations, content providers and private enterprise customers. Our ESS segment also provides telemetry, tracking and control (“TT&C”) services for satellites owned by DISH Network and technical consulting services that are billed by the hour. Generally, our service contracts with customers contain a single performance obligation and therefore there is no need to allocate the transaction price. We transfer control and recognize revenue for satellite services at the point in time or over the period when the services are rendered. Other Sales and Value Added Taxes, Universal Service Fees and other taxes that we collect concurrent with revenue producing activities are excluded from revenue. Shipping and handling costs associated with outbound freight are accounted for as a fulfillment cost after control over a product has transferred to the customer and are included in Cost of sales - equipment in our Consolidated Statements of Operations and Comprehensive Income (Loss) at the time of shipment. Contract Balances Trade Accounts Receivable Trade accounts receivable includes amounts billed and currently due from customers and represents our unconditional rights to consideration arising from our performance under our customer contracts. Trade accounts receivable also includes amounts due from customers under our leasing arrangements. We make ongoing estimates relating to the collectibility of our trade accounts receivable and maintain an allowance for estimated losses resulting from the inability of our customers to make the required payments. In determining the amount of the allowance, we consider historical levels of credit losses and make judgments about the creditworthiness of our customers based on ongoing credit evaluations. Past due trade accounts receivable balances are written off when our internal collection efforts have been unsuccessful. Bad debt expense related to our trade accounts receivable and other contract assets is included in Selling, general and administrative expenses in our Consolidated Statements of Operations and Comprehensive Income (Loss). Contract Assets and Contract Liabilities Contract assets represent revenue that we have recognized in advance of billing the customer and are included in Trade accounts receivable and contract assets, net or Other noncurrent assets, net in our Consolidated Balance Sheets based on the expected timing of customer payment. Our contract assets include amounts that we referred to as Contracts in Process in prior periods. Our contract assets typically relate to our long-term contracts where we recognize revenue using the cost-based input method and the revenue recognized exceeds the amount billed to the customer. Contract liabilities consist of advance payments and billings in excess of revenue recognized under customer contracts and are included in Contract liabilities or Other noncurrent liabilities in our Consolidated Balance Sheets based on the timing of when we expect to recognize revenue. Contract liabilities include amounts that we referred to as deferred revenue in prior periods. We recognize contract liabilities as revenue after all revenue recognition criteria have been met. Contract Acquisition and Fulfillment Costs Contract Acquisition Costs Our contract acquisition costs represent incremental direct costs of obtaining a contract and consist primarily of sales incentives paid to employees and third-party representatives. When we determine that our contract acquisition costs are recoverable, we defer and amortize the costs over the contract term, or over the estimated life of the customer relationship if anticipated renewals are expected and the incentives payable upon renewal are not commensurate with the initial incentive. We amortize contract acquisition costs in proportion to the revenue to which the costs relate. We expense sales incentives as incurred if the expected amortization period is one year or less. Unamortized contract acquisition costs are included in Other noncurrent assets, net in our Consolidated Balance Sheets and related amortization expense is included in Selling, general and administrative expenses in our Consolidated Statements of Operations and Comprehensive Income (Loss). Contract Fulfillment Costs We recognize costs to fulfill a contract as an asset when the costs relate directly to a specific contract, the costs generate or enhance our resources that will be used in satisfying future performance obligations and the costs are expected to be recovered. We may incur such costs on certain contracts that require initial setup activities in advance of the transfer of goods or services to the customer. We amortize these costs in proportion to the revenue to which the costs relate. Unamortized contract fulfillment costs are included in Other noncurrent assets, net in our Consolidated Balance Sheets and related amortization expense is included in Cost of sales - services and other in our Consolidated Statements of Operations and Comprehensive Income (Loss). Foreign Currency The functional currency for certain of our foreign operations is determined to be the local currency. Accordingly, we translate assets and liabilities of these foreign entities from their local currencies to U.S. dollars using period-end exchange rates and translate income and expense accounts at monthly average rates. The resulting translation adjustments are reported in other comprehensive income (loss) as Foreign currency translation adjustments in our Consolidated Statements of Operations and Comprehensive Income (Loss) . Except in certain uncommon circumstances, we have not recorded deferred income taxes related to our foreign currency translation adjustments. Gains and losses resulting from re-measurement of monetary assets and liabilities denominated in foreign currencies into the functional currency are recognized in Other, net in our Consolidated Statements of Operations and Comprehensive Income (Loss). Cash and Cash Equivalents We consider all liquid investments purchased with an original maturity of 90 days or less to be cash equivalents. Cash equivalents as of December 31, 2018 and 2017 primarily consisted of commercial paper, government bonds, corporate notes, and money market funds. The amortized cost of these investments approximates their fair value. Inventory Inventory is stated at the lower of cost, determined using the first-in, first-out (“FIFO”) method, or net realizable value. Cost of inventory consists primarily of materials, direct labor and indirect overhead incurred in the procurement and manufacturing of our products. We use standard costing methodologies in determining the cost of certain of our finished goods and work-in-process inventories. We determine net realizable value using our best estimates of future use or recovery, considering the aging and composition of inventory balances, the effects of technological and/or design changes, forecasted future product demand based on firm or near-firm customer orders, and alternative means of disposition of excess or obsolete items. We recognize losses within operating income when we determine that the cost of inventory and commitments to purchase inventory exceed net realizable value. Capitalized Software Costs Internal-Use Software Costs related to the procurement and development of software for internal-use are capitalized and amortized using the straight-line method over the estimated useful life of the software, not in excess of five years . Capitalized costs of internal-use software are included in Property and equipment, net in our Consolidated Balance Sheets. Externally Marketed Software Costs related to the procurement and development of software for externally marketed software are capitalized and amortized using the straight-line method over the estimated useful life of the software, not in excess of five years . Capitalized costs of externally marketed software are included in Other noncurrent assets, net in our Consolidated Balance Sheets. Externally marketed software generally is installed in the equipment we sell or lease to customers. We conduct software program reviews for externally marketed capitalized software costs at least annually, or as events and circumstances warrant such a review, to determine if capitalized software development costs are recoverable and to ensure that costs associated with programs that are no longer generating revenue are expensed. Marketable Investment Securities Our marketable investment securities portfolio consists of investments in debt and equity instruments with readily determinable fair values. Debt Securities We classify all of our debt securities as available for sale based on our investment strategy for the securities. Generally, we recognize periodic changes in the difference between fair value and amortized cost in Unrealized gains on available-for-sale securities and other in our Consolidated Statements of Operations and Comprehensive Income (Loss). Realized gains and losses upon sales of debt securities are reclassified from other comprehensive income (loss) and recognized on the trade date in Gains and losses on investments, net in our Consolidated Statements of Operations and Comprehensive Income (Loss). We use the FIFO method to determine the cost basis on sales of debt securities. Interest income from debt securities is reported in Interest income in our Consolidated Statements of Operations and Comprehensive Income (Loss). We could realize proceeds from certain investments prior to their contractual maturity if we sell these securities before such maturity. We evaluate our available-for-sale debt securities portfolio periodically to determine whether declines in the fair value of these securities are other-than-temporary. Our evaluation considers, among other things, the length of time and the extent to which the fair value of such security has been lower than amortized cost, market and company-specific factors related to the security and our intent and ability to hold the investment to maturity or when it recovers its value. We generally consider a decline to be other-than-temporary when: (i) we intend to sell the security, (ii) it is more likely than not that we will be required to sell the security before maturity or when it recovers its value, or (iii) we do not expect to recover the amortized cost of the security at maturity. Declines in the fair value of available-for-sale debt securities that are determined to be other-than-temporary are reclassified from other comprehensive income (loss) and recognized in Net income , in our Consolidated Statements of Operations and Comprehensive Income (Loss), thus establishing a new cost basis for the investment. Additionally, from time to time we make strategic investments in corporate debt securities. We may elect to account for these investments using the fair value option when it reduces accounting complexity. When we have made this election, we recognize periodic changes in fair value of these investments in Gains (losses) on investments, net in our Consolidated Statements of Operations and Comprehensive Income (Loss). Interest income from these securities is reported in Interest income in our Consolidated Statements of Operations and Comprehensive Income (Loss). Equity Securities Prior to January 1, 2018, we classified our marketable equity securities as available-for-sale or trading securities, depending on our investment strategy for the securities. For available-for-sale securities, we recognized periodic changes in the difference between fair value and cost in Unrealized gains (losses) on available-for-sale securities and other in our Consolidated Statements of Operations and Comprehensive Income (Loss). Realized gains and losses upon sale of available-for-sale securities were reclassified from other comprehensive income (loss) and recognized on the trade date in Gains (losses) on investments, net in our Consolidated Statements of Operations and Comprehensive Income (Loss). We used the FIFO method to determine the cost basis on sales of available-for-sale securities. For trading securities, we recognized periodic changes in the fair value of the securities in Gains and losses on investments, net in our Consolidated Statements of Operations and Comprehensive Income (Loss). Effective January 1, 2018, we adopted Accounting Standards Update (“ASU”) No. 2016-01, Financial Instruments (the “New Investment Standard”) , which established new requirements for investments in equity securities in ASC Topic 321, Investments - Equity Securities . Accordingly, beginning in 2018, we recognize periodic changes in the fair value of all of our equity securities with a readily determinable fair value that are not accounted for using the equity method in Gains and losses on investments, net in our Consolidated Statements of Operations and Comprehensive Income (Loss). We recognize dividend income on equity securities on the ex-dividend date and report such income in Other, net in our Consolidated Statements of Operations and Comprehensive Income (Loss). Investments in Unconsolidated Entities Our investments in unconsolidated entities consist of investments in equity securities that are not publicly traded and do not have readily determinable fair values. Equity Method We use the equity method to account for investments when we have the ability to exercise significant influence on the operating decisions of the investee. Such investments in unconsolidated entities are initially recorded at cost and subsequently adjusted for our proportionate share of the net earnings or loss of the investee, which is reported in Equity in earnings of unconsolidated affiliate in our Consolidated Statements of Operations and Comprehensive Income (Loss). The carrying amount of such investments may include a component of goodwill if the cost of our investment exceeds the fair value of the underlying identifiable assets and liabilities of the investee. Dividends received from equity method investees reduce the carrying amount of the investment. We defer, to the extent of our ownership interest in the investee, recognition of intra-entity profits on sales of equipment to the investee until the investee has charged the cost of the equipment to expense in a subsequent sale to a third party or through depreciation. In these circumstances, we report the gross amounts of revenue and cost of sales in the Consolidated Statements of Operations and Comprehensive Income (Loss) and include the intra-entity profit eliminations within Equity in earnings of unconsolidated affiliate . Other Investments Prior to January 1, 2018, we accounted for other investments without a readily determinable fair value using the cost method. In connection with our adoption of the New Investment Standard as of January 1, 2018, we have elected to measure such investments at cost, adjusted for changes resulting from impairments and observable price changes in orderly transactions for identical or similar securities of the same issuer. We consider information in periodic financial statements and other documentation provided by our investees and we may make inquiries of investee management to determine whether observable price changes have occurred. Impairment Considerations We evaluate all of our investments in unconsolidated entities periodically to determine whether events or changes in circumstances have occurred that may have a significant adverse effect on the fair value of the investment. As part of our evaluation, we review available information such as business plans and current financial statements of these companies for factors that may indicate an impairment of our investments. Such factors may include, but are not limited to, unprofitable operations, negative cash flow, material litigation, violations of debt covenants, bankruptcy and changes in business strategy. When we determine that an investment is impaired, we adjust the carrying amount of the investment to its estimated fair value and recognize the impairment loss in Gains and losses on investments, net in our Consolidated Statements of Operations and Comprehensive Income (Loss). Property and Equipment Property and equipment is stated at cost, less accumulated depreciation. Depreciation is recorded on a straight-line basis over lives ranging from one to 40 years . The cost of our satellites includes construction costs, including the present value of in-orbit incentives payable to the satellite manufacturer, launch costs, capitalized interest, and related insurance premiums. Repair and maintenance costs are charged to expense when incurred. Costs of renewals and betterments are capitalized. Impairment of Long-lived Assets We review our long-lived assets for recoverability whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. The evaluation is performed at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. For assets held and used in operations, the asset is not recoverable if the carrying amount of the asset exceeds its undiscounted estimated future net cash flows. When an asset is not recoverable, we adjust the carrying amount of such asset to its estimated fair value and recognize the impairment loss in Net Income in our Consolidated Statements of Operations. Assets to be disposed of by sale are reported at the lower of the carrying amount or fair value less costs to sell. Goodwill Goodwill represents the excess of the cost of acquired businesses over the estimated fair value assigned to the identifiable assets acquired and liabilities assumed. We do not amortize goodwill, but test goodwill for impairment annually, or more frequently if circumstances indicate impairment may exist. Our goodwill as of December 31, 2018 and 2017 is assigned to reporting units of our Hughes segment. We test such goodwill for impairment in the second fiscal quarter. The goodwill impairment test involves a comparison of the fair value of a reporting unit with its carrying amount, including goodwill. We typically estimate fair value of reporting units using discounted cash flow techniques, which includes significant assumptions about prospective financial information, terminal value and discount rates (Level 3 inputs). If the reporting unit’s carrying amount exceeds its estimated fair value, we recognize an impairment loss equal to such excess, not to exceed the carrying amount of goodwill. We may bypass the quantitative goodwill impairment test if we determine, based on a qualitative assessment, that it is more likely than not that the fair value of a reporting unit exceeds its carrying amount including goodwill. Regulatory Authorizations and Other Intangible Assets At acquisition and periodically thereafter, we evaluate our intangible assets to determine whether their useful lives are finite or indefinite. We consider our intangible assets to have indefinite lives when no significant legal, regulatory, contractual, competitive, economic, or other factors limit their useful lives. Intangible assets that have finite lives are amortized over their estimated useful lives, ranging from approximately one to 20 years . When we expect to incur significant costs to renew or extend finite-lived intangible assets, we amortize the total initial and estimated renewal costs over the combined initial and expected renewal terms. In such instances, actual renewal costs are capitalized when they are incurred. We test intangible assets with finite lives for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable (see Impairment of Long-lived Assets above). We do not amortize our indefinite-lived intangible assets, but test those assets for impairment annually or more frequently if circumstances indicate that it is more likely than not that the asset may be impaired. Costs incurred to maintain or renew indefinite-lived intangible assets are expensed as incurred. Our indefinite-lived intangible assets include Federal Communications Commission (“FCC”) authorizations and certain other contractual or regulatory rights to use spectrum at specified orbital locations (collectively “Regulatory Authorizations”). We have determined that our FCC authorizations generally have indefinite useful lives due to the following: • FCC authorizations are non-depleting assets; • renewal satellite applications generally are authorized by the FCC subject to certain conditions, without substantial cost under a stable regulatory, legislative, and legal environment; • expenditures required to maintain the authorization are not significant; and • we intend to use these authorizations indefinitely. Debt Issuance Costs Costs of issuing debt generally are deferred and amortized utilizing the effective interest method with amortization included in Interest expense, net of amounts capitalized in our Consolidated Statements of Operations and Comprehensive Income (Loss). We report unamortized debt issuance costs as a reduction of the related long-term debt in our Consolidated Balance Sheets. Income Taxes We are included in the consolidated federal income tax return of EchoStar. We recognize a provision or benefit for income taxes currently payable or receivable and for income tax amounts deferred to future periods based upon a separate return allocation method which results in income tax expense that approximates the expense that would result if we were a stand-alone entity. Deferred tax assets and liabilities are recorded based on enacted tax laws for the estimated future tax effects of differences that exist between the financial reporting carrying amount and tax basis of assets and liabilities. Deferred tax assets are offset by valuation allowances when we determine it is more likely than not that such deferred tax assets will not b

Satellites As of December 31, 2018, our satellite fleet consisted of 15 satellites, 10 of which are owned and five of which are leased. They are all in geosynchronous orbit, approximately 22,300 miles above the equator. We depreciate our owned satellites on a straight-line basis over the estimated useful life of each satellite. We depreciate our leased satellites on a straight-line basis over their respective lease terms.

(6) EchoStar contributed the EchoStar XIX satellite to us in February 2017. Recent Developments EchoStar I and EchoStar VI. The EchoStar I and EchoStar VI satellites were removed from their orbital locations and retired from commercial service in January 2018 and May 2018, respectively. The retirement of these satellites has not had, and is not expected to have, a material impact on our results of operations or financial position. EchoStar 105/SES-11. The EchoStar 105/SES-11 satellite was launched in October 2017 and was placed into service in November 2017 at the 105 degree west longitude orbital location. Pursuant to agreements that we entered into in August 2014, we funded substantially all construction, launch and other costs associated with the EchoStar 105/SES-11 satellite and transferred the C-, Ku- and Ka-band payloads to two affiliates of SES Americom, Inc. (“SES”) after the launch date, while retaining the right to use the entire Ku-band payload on the satellite for an initial ten-year term, with an option for us to renew the agreement on a year-to-year basis. In October 2017, we recorded a $77 million receivable from SES in Other current assets in the Consolidated Balance Sheets , representing capitalized costs allocable to certain satellite payloads controlled by SES, and we reduced our carrying amount of the satellite by such amount. In January 2018, we received payment from SES for the receivable plus accrued interest. Our leased Ku-band payload on the EchoStar 105/SES-11 satellite has replaced the capacity we had on the AMC-15 satellite. Telesat T19V. In September 2015, we entered into agreements pursuant to which affiliates of Telesat Canada will provide to us Ka-band capacity on the Telesat T19V satellite at the 63 degree west longitude orbital location for a 15-year term. The Telesat T19V satellite was launched in July 2018 and placed into service in October 2018. This satellite augments the capacity being provided by the EUTELSAT 65 West A and EchoStar XIX satellites in Central and South America. Satellite Anomalies and Impairments Our satellites may experience anomalies from time to time, some of which may have a significant adverse effect on their remaining useful lives, the commercial operation of the satellites or our operating results or financial position. We are not aware of any anomalies with respect to our owned or leased satellites that have had any such significant adverse effect during the year ended December 31, 2018 . There can be no assurance, however, that anomalies will not have any such adverse effects in the future. In addition, there can be no assurance that we can recover critical transmission capacity in the event one or more of our satellites were to fail. The EchoStar X satellite experienced anomalies in the past which affected seven solar array circuits. In December 2017, the satellite experienced anomalies which affected one additional solar array circuit reducing the number of functional solar array circuits to 16. As a result of these anomalies, we had a reduction in revenue of $4 million for the year ended December 31, 2018 We historically have not carried in-orbit insurance on our satellites because we have assessed that the cost of insurance is not economical relative to the risk of failures. Therefore, we generally bear the risk of any in-orbit failures. Pursuant to the terms of the agreements governing certain portions of our indebtedness, we are required, subject to certain limitations on coverage, to maintain in-orbit insurance for our SPACEWAY 3, EchoStar XVI and EchoStar XVII satellites. Our other satellites, either in orbit or under construction, are not covered by launch or in-orbit insurance. We will continue to assess circumstances going forward and make insurance decisions on a case-by-case basis. We evaluate our satellites for impairment and test for recoverability whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Certain of the anomalies previously disclosed may be considered to represent a significant adverse change in the physical condition of a particular satellite. However, based on the redundancy designed within each satellite, certain of these anomalies are not necessarily considered to be significant events that would require a test of recoverability.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill The excess of the cost of an acquired business over the fair values of net tangible and identifiable intangible assets at the time of the acquisition is recorded as goodwill. Goodwill is assigned to the reporting units within our operating segments and is subject to impairment testing annually, or more frequently when events or changes in circumstances indicate the fair value of a reporting unit is more likely than not less than its carrying amount. As of December 31, 2018 and 2017 , all of our goodwill was assigned to reporting units of our Hughes segment. We test this goodwill for impairment annually in the second quarter. Based on our impairment testing in the second quarter of 2018, our goodwill is considered to be not impaired. Other Intangible Assets Our other intangible assets, which are subject to amortization, consisted of the following: Weighted Average Useful Life (in Years) As of December 31, 2018 2017 Cost Accumulated Amortization Carrying Amount Cost Accumulated Amortization Carrying Amount (In thousands) Customer relationships 8 $ 270,300 $ (244,787 ) $ 25,513 $ 270,300 $ (231,642 ) $ 38,658 Technology-based 6 51,400 (51,400 ) — 51,417 (51,417 ) — Trademark portfolio 20 29,700 (11,261 ) 18,439 29,700 (9,776 ) 19,924 Total other intangible assets $ 351,400 $ (307,448 ) $ 43,952 $ 351,417 $ (292,835 ) $ 58,582 Customer relationships are amortized predominantly in relation to the expected contribution of cash flow to the business over the life of the intangible asset. Other intangible assets are amortized on a straight-line basis over the periods the assets are expected to contribute to our cash flows. Intangible asset amortization expense, including amortization of externally marketed capitalized software, was $38 million , $42 million and $45 million for the years ended December 31, 2018 , 2017 and 2016 , respectively.

Equity Method Investments and Joint Ventures [Abstract]
Investments in Unconsolidated Entities	INVESTMENTS IN UNCONSOLIDATED ENTITIES We have strategic investments in certain non-publicly traded equity securities that do not have a readily determinable fair value. We account for most of these investments using the equity method. We accounted for other investments in such equity securities using the cost method of accounting prior to January 1, 2018. In connection with our adoption of the New Investment Standard effective January 1, 2018 (see Note 2), we elected to measure our equity securities without a readily determinable fair value, other than those accounted for using the equity method, at cost adjusted for changes resulting from impairments, if any, and observable price changes in orderly transactions for the identical or similar securities of the same issuer. For the year ended December 31, 2018 , we did not identify any observable price changes requiring an adjustment to our investments. Our investments in unconsolidated entities consisted of the following: As of December 31, 2018 2017 (In thousands) Investments in unconsolidated entities: Equity method $ 110,931 $ 15,149 Other equity investments without a readily determinable fair value 15,438 15,438 Total investments in unconsolidated entities $ 126,369 $ 30,587 We recorded cash distributions from our investments accounted for using the equity method of $10 million , $19 million and $10 million for the years ended December 31, 2018 , 2017 and 2016

The 2019 Senior Secured Notes mature on June 15, 2019. Interest accrues at an annual rate of 6 1/2% and is payable semi-annually in cash, in arrears on June 15 and December 15 of each year. As of December 31, 2018 and 2017 , the outstanding principal balance on the 2019 Senior Secured Notes was $921 million and $990 million , respectively. The decrease in the principal outstanding was due to our repurchase of $69 million in the open market during 2018. We recorded a loss on the repurchase of $1 million . On June 1, 2011, we also issued $900 million aggregate principal amount of 7 5/8% Senior Unsecured Notes due 2021 (the “2021 Senior Unsecured Notes,”) at an issue price of 100.0% , pursuant to an Unsecured Indenture dated June 1, 2011 (together with the “2011 Secured Indenture”, the “2011 Indentures”). The 2021 Senior Unsecured Notes mature on June 15, 2021. Interest accrues at an annual rate of 7 5/8% and is payable semi-annually in cash, in arrears on June 15 and December 15 of each year. As of December 31, 2018 and 2017 , the outstanding principal balance on the 2021 Senior Unsecured Notes was $900 million . 2026 Senior Secured Notes and 2026 Senior Unsecured Notes On July 27, 2016, we issued $750 million aggregate principal amount of 5 1/4% Senior Secured Notes due 2026 (the “2026 Senior Secured Notes” and, together with the 2019 Senior Secured Notes, the “Secured Notes”) at an issue price of 100.0% , pursuant to an indenture dated July 27, 2016 (the “2016 Secured Indenture”) and $750 million aggregate principal amount of 6 5/8% Senior Unsecured Notes due 2026 (the “2026 Senior Unsecured Notes” and, together with the 2021 Senior Unsecured Notes, the “Unsecured Notes”) at an issue price of 100.0% , pursuant to an indenture dated July 27, 2016 (together with the 2011 Indentures and the 2016 Secured Indenture, the “Indentures”). The 2019 Senior Secured Notes, the 2021 Senior Unsecured Notes, the 2026 Senior Secured Notes and the 2026 Senior Unsecured Notes are referred to collectively as the “Notes” and individually as a series of the Notes. The 2026 Senior Secured Notes and the 2026 Senior Unsecured Notes (collectively, the “2026 Notes”) mature on August 1, 2026. Interest on the 2026 Senior Secured Notes accrues at an annual rate of 5 1/4% and interest on the 2026 Senior Unsecured Notes accrues at an annual rate of 6 5/8%. Interest on the 2026 Notes is payable semi-annually in cash, in arrears on February 1 and August 1 of each year commencing February 1, 2017. At each of December 31, 2018 and 2017 , the outstanding principal balance on each of the 2026 Senior Secured Notes and the 2026 Senior Unsecured Notes was $750 million , respectively. Additional Information Relating to the Notes Each series of the Notes is redeemable, in whole or in part, at any time at a redemption price equal to 100.0% of the principal amount thereof plus a “make-whole” premium, as defined in the applicable Indenture, together with accrued and unpaid interest, if any, to the date of redemption. We may also redeem up to 10% of the outstanding 2026 Senior Secured Notes per year prior to August 1, 2020 at a redemption price equal to 103% of the principal amount thereof plus accrued and unpaid interest to the date of redemption. In addition, we may, at any time prior to August 1, 2019, with the net cash proceeds from certain equity offerings or capital contributions, redeem up to 35% of the 2026 Senior Secured Notes, at 105.250% of the principal amount, and up to 35% of the 2026 Senior Unsecured Notes, at a redemption price equal to 106.625% of the principal amount plus, in each case, accrued and unpaid interest on the 2026 Notes being redeemed to the date of redemption. The Secured Notes are: • our secured obligations ; • secured by security interests in substantially all of our and certain of our subsidiaries’ existing and future tangible and intangible assets on a first priority basis, subject to certain exceptions; • ranked equally and ratably as between the 2019 Senior Secured Notes and the 2026 Senior Secured Notes; • effectively junior to our obligations that are secured by assets that are not part of the collateral that secures the respective Secured Notes, in each case, to the extent of the value of the collateral securing such obligations; • effectively senior to our existing and future unsecured obligations to the extent of the value of the collateral securing the respective Secured Notes, after giving effect to permitted liens as provided in the Indenture governing the respective Secured Notes; • senior in right of payment to all of our existing and future obligations that are expressly subordinated to the respective Secured Notes; • structurally junior to any existing and future obligations of any of our subsidiaries that do not guarantee the respective Secured Notes; and • unconditionally guaranteed, jointly and severally, on a general senior secured basis by certain of our subsidiaries, which guarantees rank equally with all of the guarantors’ existing and future unsubordinated indebtedness and effectively senior to such guarantors’ existing and future obligations to the extent of the value of the assets securing the respective Secured Notes. The Unsecured Notes are: • our unsecured senior obligations ; • ranked equally with all existing and future unsubordinated indebtedness (including as between the 2021 Senior Unsecured Notes and the 2026 Senior Unsecured Notes) and effectively junior to any secured indebtedness up to the value of the assets securing such indebtedness; • effectively junior to our obligations that are secured to the extent of the value of the collateral securing such obligations; • senior in right of payment to all of our existing and future obligations that are expressly subordinated to the respective Unsecured Notes; • structurally junior to any existing and future obligations of any of our subsidiaries that do not guarantee the respective Unsecured Notes; and • unconditionally guaranteed, jointly and severally, on a general senior secured basis by certain of our subsidiaries, which guarantees rank equally with all of the guarantors’ existing and future unsubordinated indebtedness, and effectively junior to any secured indebtedness of the guarantors up to the value of the assets securing such indebtedness. Subject to certain exceptions, the Indentures contain restrictive covenants that, among other things, impose limitations on our ability and, in certain instances, the ability of certain of our subsidiaries to: • incur additional debt; • pay dividends or make distributions on our capital stock or repurchase our capital stock; • make certain investments; • create liens or enter into sale and leaseback transactions; • enter into transactions with affiliates; • merge or consolidate with another company; • transfer and sell assets; and • allow to exist certain restrictions on the ability of certain of our subsidiaries to pay dividends, make distributions, make other payments, or transfer assets to us or our subsidiaries. In the event of a Change of Control, as defined in the respective Indentures, we would be required to make an offer to repurchase all or any part of a holder’s Notes at a purchase price equal to 101.0% of the aggregate principal amount thereof, together with accrued and unpaid interest to the date of repurchase. The Indentures provide for customary events of default for each series of the Notes, including, among other things, nonpayment, breach of the covenants in the applicable Indentures, payment defaults or acceleration of other indebtedness, a failure to pay certain judgments and certain events of bankruptcy, insolvency and reorganization. If any event of default occurs and is continuing with respect to any series of the Notes, the trustee or the holders of at least 25% in principal amount of the then outstanding Notes of such series may declare all the Notes of such series to be due and payable immediately, together with any accrued and unpaid interest. Pursuant to the terms of a registration rights agreement, we registered notes having substantially identical terms as the 2026 Notes with the Securities and Exchange Commission as part of an offer to exchange registered notes for the 2026 Notes. This exchange offer expired May 11, 2017 with 99.98% of the 2026 Notes being tendered for exchange. Debt Issuance Costs In connection with the issuance of the 2026 Notes, we incurred $8 million of debt issuance costs. For the years ended December 31, 2018 , 2017 and 2016 , we amortized $8 million , $7 million and $7 million of debt issuance costs incurred for all debt issuances, respectively, which are included in “ Interest expense, net of amounts capitalized ” in our Consolidated Statements of Operations and Comprehensive Income (Loss) . Capital Lease Obligations Our capital lease obligations reflect the present value of future minimum lease payments under noncancelable lease agreements, primarily for certain of our satellites (see Note 7 ). These agreements require monthly recurring payments, which generally include principal, interest, an amount for use of the orbital location and estimated executory costs, such as insurance and maintenance. The monthly recurring payments generally are subject to reduction in the event of failures that reduce the satellite transponder capacity. Certain of these agreements provide for extension of the initial lease term at our option. The effective interest rates for our satellite capital lease obligations range from 9.1% to 11.2% , with a weighted average of 10.7% as of December 31, 2018 . Our capital lease obligations consist primarily of our payment obligations under agreements for the Nimiq 5 and QuetzSat-1 satellites, which have remaining noncancelable terms ending in September 2024 and November 2021, respectively. As discussed in Note 16 , we have subleased transponders on these satellites to DISH Network. Future minimum lease payments under our capital lease obligations, together with the present value of the net minimum lease payments as of December 31, 2018 , are as follows: Amount (In thousands) For the Years Ending December 31, 2019 $ 88,615 2020 88,395 2021 84,248 2022 63,484 2023 63,360 Thereafter 47,520 Total minimum lease payments 435,622 Less: Amount representing use of the orbital location and estimated executory costs including profit thereon, included in total minimum lease payments (136,799 ) Net minimum lease payments 298,823 Less: Amount representing interest (70,121 ) Present value of net minimum lease payments 228,702 Less: Current portion (40,662 ) Long-term portion of capital lease obligations $ 188,040 We received rental income from the sublease of our capital lease satellites of approximately $132 million for each of the years ended December 31, 2018 , 2017 and 2016 . As of December 31, 2018 , our future minimum sublease rental income was $216 million relating to such satellites. The subleases have a remaining weighted average term of two years

We evaluate our deferred tax assets for realization and record a valuation allowance when we determine that it is more likely than not that the amounts will not be realized. Overall, our net deferred tax assets were offset by a valuation allowance of $49 million and $40 million as of December 31, 2018 and 2017 , respectively. The change in the valuation allowance primarily relates to a decrease in realized and unrealized gains that are capital in nature, and an increase in the net operating loss carryforwards of certain foreign subsidiaries. Tax benefits of net operating loss and tax credit carryforwards are evaluated on an ongoing basis, including a review of historical and projected future operating results, the eligible carryforward period, and other circumstances. As of December 31, 2018 , we had net operating loss carryforwards of $193 million , including $119 million of foreign net operating loss carryforwards. A substantial portion of these net operating loss carryforwards will begin to expire in 2029. As of December 31, 2018 , we have tax credit carryforwards of $40 million and $2 million for federal and state income tax purposes, respectively. If not utilized, the federal tax credit carryforwards will begin to expire in 2026 and the state tax credit carryforwards will begin to expire in 2018. As of December 31, 2018 , we had undistributed earnings attributable to foreign subsidiaries for which no provision for U.S. income taxes or foreign withholding taxes has been made because it is expected that such earnings will be reinvested outside the U.S. indefinitely. It is not practicable to determine the amount of the unrecognized deferred tax liability at this time. However, due to the one-time transition tax on the deemed repatriation of post-1986 undistributed foreign subsidiary earnings, the majority of previously unremitted earnings have now been subjected to U.S. federal income tax. Accounting for the U.S. Tax Cuts and Jobs Act The Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”) was enacted in December 2017 and has significantly impacted our effective tax rate and the tax benefit calculated for the year ended December 31, 2017. For the year ended December 31, 2017, we recorded a benefit of $283 million to reflect the change in the value of our deferred tax assets and liabilities resulting from the change in the federal corporate tax rate from 35% to 21%. For the year ended December 31, 2018, we recorded an additional benefit of $0.8 million upon completion of our analysis. This amount included an estimate of zero related to valuation allowances on foreign tax credit carryovers. We account for the effects, if any, of the global intangible low-taxed income provisions (“GILTI”) of the 2017 Tax Act as incurred. We also recorded a tax provision of nil related to the tax on deemed mandatory repatriation of our unrepatriated foreign earnings. Accounting for Uncertainty in Income Taxes In addition to filing U.S. federal income tax returns with EchoStar, we file income tax returns in all states that impose an income tax. We also file income tax returns in the United Kingdom, Brazil, India and a number of other foreign jurisdictions. We generally are open to income tax examination in these foreign jurisdictions for taxable years beginning in 2003. As of December 31, 2018 , we are currently being audited by the Indian tax authorities for fiscal years 2003 through 2012. We have no other on-going significant income tax examinations in process in our foreign jurisdictions. A reconciliation of the beginning and ending amount of unrecognized income tax benefits is as follows: For the Years Ended December 31, Unrecognized tax benefit 2018 2017 2016 (In thousands) Balance as of beginning of period $ 7,950 $ 7,057 $ 3,508 Additions based on tax positions related to the current year 572 656 388 Additions based on tax positions related to prior years — 237 3,161 Reductions based on tax positions related to prior years (656 ) — — Balance as of end of period $ 7,866 $ 7,950 $ 7,057 As of December 31, 2018 , we had $8 million of unrecognized income tax benefits, all of which, if recognized, would affect our effective tax rate. As of December 31, 2017 , we had $8 million of unrecognized income tax benefits, all of which, if recognized, would affect our effective tax rate. We do not believe that the total amount of unrecognized income tax benefits will significantly increase or decrease within the next twelve months due to the lapse of statute of limitations or settlement with tax authorities. For the years ended December 31, 2018 , 2017 and 2016 , our income tax provision included an insignificant amount of interest and penalties. Estimates of our uncertain tax positions are made based upon prior experience and are updated in light of changes in facts and circumstances. However, due to the uncertain and complex application of tax regulations, it is possible that the ultimate resolution of audits may result in liabilities which could be materially different from these estimates. In such an event, we will record additional income tax provision or benefit in the period in which such resolution occurs.

Employee Benefit Plans

Employee Benefit Plans	12 Months Ended

Pension and Other Postretirement Benefits Cost (Reversal of Cost) [Abstract]
Employee Benefit Plans	EMPLOYEE BENEFIT PLANS Employee Stock Purchase Plan EchoStar has an employee stock purchase plan (the “ESPP”), under which it is authorized to issue 5.0 million shares of EchoStar Class A common stock. As of December 31, 2018 , EchoStar had approximately 2.5 million shares of Class A common stock which remain available for issuance under the ESPP. Generally, all full-time employees who have been employed by EchoStar for at least one calendar quarter are eligible to participate in the ESPP. Employee stock purchases are made through payroll deductions. Under the terms of the ESPP, each employee’s deductions are limited so that the maximum they may purchase under the ESPP is $25,000 in fair value of Class A common stock per year. Stock purchases are made on the last business day of each calendar quarter at 85.0% of the closing price of EchoStar’s Class A common stock on that date. For the years ended December 31, 2018 , 2017 and 2016 , employee purchases of EchoStar Class A common stock through the ESPP totaled approximately 235,000 shares, 169,000 shares and 209,000 shares, respectively. 401(k) Employee Savings Plans Under the EchoStar 401(k) Plan (“the Plan”), eligible employees are entitled to contribute up to 75.0% of their eligible compensation subject to the maximum contribution limit provided by the Internal Revenue Code of 1986, as amended (the “Code”). Eligible employees have the option to contribute up to 75% of their eligible compensation on a pre-tax and/or after-tax basis subject to the Code limits. All employee contributions to the Plan are immediately vested. EchoStar matches 50 cents on the dollar for the first 6.0% of each employee’s salary contributions to the Plan for a total of 3.0% match on a pre-tax basis up to a maximum of $7,500 annually. EchoStar’s match is calculated each pay period there is an employee contribution. In addition, EchoStar may make an annual discretionary contribution to the Plan to be made in cash or EchoStar’s stock. EchoStar’s contributions under the Plan vest at 20.0% per year and are 100.0% vested after an eligible employee has completed five years of employment. Forfeitures of unvested participant balances may be used to fund matching and discretionary contributions. During the years ended December 31, 2018 , 2017 and 2016 , we recognized matching contributions, net of forfeitures, of $5 million , $5 million and $4 million , respectively, and EchoStar made discretionary contributions to our employees of shares of its Class A common stock, net of forfeitures, with a fair value of $8 million , $7 million and $6 million

We incurred satellite-related expenses of $101 million , $140 million and $144 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. The table above does not include amounts related to deferred tax liabilities, unrecognized tax positions and certain other amounts recorded in our noncurrent liabilities as the timing of any payments is uncertain. The table also excludes long-term deferred revenue and other long-term liabilities that do not require future cash payments. In certain circumstances, the dates on which we are obligated to pay our contractual obligations could change. Rent Expense For the years ended December 31, 2018 , 2017 and 2016 , we recorded $26 million , $28 million and $19 million , respectively, of operating lease expense relating to the leases of office space, equipment, and other facilities. Contingencies Patents and Intellectual Property Many entities, including some of our competitors, have or may have in the future patents and other intellectual property rights that cover or affect products or services directly or indirectly related to those that we offer. We may not be aware of all patents and other intellectual property rights that our products and services may potentially infringe. Damages in patent infringement cases can be substantial, and in certain circumstances can be tripled. Further, we cannot estimate the extent to which we may be required in the future to obtain licenses with respect to intellectual property rights held by others and the availability and cost of any such licenses. Various parties have asserted patent and other intellectual property rights with respect to our products and services. We cannot be certain that these parties do not own the rights they claim, that these rights are not valid or that our products and services do not infringe on these rights. Further, we cannot be certain that we would be able to obtain licenses from these parties on commercially reasonable terms or, if we were unable to obtain such licenses, that we would be able to redesign our products and services to avoid infringement. Separation Agreement and Share Exchange In connection with EchoStar’s spin-off from DISH in 2008 (the “Spin-off”), EchoStar entered into a separation agreement with DISH Network that provides, among other things, for the division of certain liabilities, including liabilities resulting from litigation. Under the terms of the separation agreement, EchoStar assumed certain liabilities that relate to its and our business, including certain designated liabilities for acts or omissions that occurred prior to the Spin-off. Certain specific provisions govern intellectual property related claims under which, generally, EchoStar will only be liable for its acts or omissions following the Spin-off and DISH Network will indemnify EchoStar for any liabilities or damages resulting from intellectual property claims relating to the period prior to the Spin-off, as well as DISH Network’s acts or omissions following the Spin-off. Additionally, in connection with the Share Exchange, EchoStar entered into a share exchange agreement and other agreements which provide, among other things, for the division of certain liabilities, including liabilities relating to taxes, intellectual property and employees and liabilities resulting from litigation and the assumption of certain liabilities that relate to the transferred businesses and assets. These agreements also contain additional indemnification provisions between EchoStar and us and DISH Network for certain pre-existing liabilities and legal proceedings. Litigation We are involved in a number of legal proceedings concerning matters arising in connection with the conduct of our business activities. Many of these proceedings are at preliminary stages and/or seek an indeterminate amount of damages. We regularly evaluate the status of the legal proceedings in which we are involved to assess whether a loss is probable and to determine if accruals are appropriate. We record an accrual for litigation and other loss contingencies when we determine that a loss is probable and the amount of the loss can be reasonably estimated. If accruals are not appropriate, we further evaluate each legal proceeding to assess whether an estimate of possible loss or range of loss can be made. There can be no assurance that legal proceedings against us will be resolved in amounts that will not differ from the amounts of our recorded accruals. Legal fees and other costs of defending litigation are charged to expense as incurred. For certain cases, management is unable to predict with any degree of certainty the outcome or provide a meaningful estimate of the possible loss or range of possible loss because, among other reasons, (i) the proceedings are in various stages; (ii) damages have not been sought or specified; (iii) damages are unsupported, indeterminate and/or exaggerated in management’s opinion; (iv) there is uncertainty as to the outcome of pending trials, appeals or motions; (v) there are significant factual issues to be resolved; and/or (vi) there are novel legal issues or unsettled legal theories to be presented or a large number of parties are involved (as with many patent-related cases). Except as described below, however, management does not believe, based on currently available information, that the outcomes of these proceedings will have a material effect on our financial condition, operating results or cash flows, though there is no assurance that the resolution and outcomes of these proceedings, individually or in the aggregate, will not be material to our financial condition, operating results or cash flows for any particular period, depending, in part, upon the operating results for such period. We intend to vigorously defend the proceedings against us. In the event that a court or jury ultimately rules against us, we may be subject to adverse consequences, including, without limitation, substantial damages, which may include treble damages, fines, penalties, compensatory damages and/or other equitable or injunctive relief that could require us to materially modify our business operations or certain products or services that we offer to our consumers. Elbit On January 23, 2015, Elbit Systems Land and C4I LTD and Elbit Systems of America Ltd. (together referred to as “Elbit”) filed a complaint against our subsidiary Hughes Network Systems, L.L.C. (“HNS”), as well as against Black Elk Energy Offshore Operations, LLC, Bluetide Communications, Inc. and Helm Hotels Group, in the U.S. District Court for the Eastern District of Texas, alleging infringement of U.S. Patent Nos. 6,240,073 (the “073 patent”) and 7,245,874 (“874 patent”). The 073 patent is entitled “Reverse Link for a Satellite Communication Network” and the 874 patent is entitled “Infrastructure for Telephony Network.” Elbit alleges that the 073 patent is infringed by broadband satellite systems that practice the Internet Protocol Over Satellite standard. Elbit alleges that the 874 patent is infringed by the manufacture and sale of broadband satellite systems that provide cellular backhaul service via connections to E1 or T1 interfaces at cellular backhaul base stations. On April 2, 2015, Elbit filed an amended complaint removing Helm Hotels Group as a defendant, but making similar allegations against a new defendant, Country Home Investments, Inc. On November 3 and 4, 2015 and January 22, 2016, the defendants filed petitions before the United States Patent and Trademark Office (“USPTO”) challenging the validity of the patents in suit, which the USPTO subsequently declined to institute. On April 13, 2016, the defendants answered Elbit’s complaint. At Elbit’s request, on June 26, 2017, the court dismissed Elbit’s claims of infringement against all parties other than HNS. Trial commenced on July 31, 2017. On August 7, 2017, the jury returned a verdict that the 073 patent was valid and infringed, and awarded Elbit approximately $21 million. The jury also found that such infringement of the 073 patent was not willful and that the 874 patent was not infringed. On March 30, 2018, the court ruled on post-trial motions, upholding the jury’s findings and awarding Elbit attorneys’ fees in an amount that has not yet been specified. As a result of pre-judgment interest, costs and unit sales through the 073 patent’s expiration in November 2017, the jury verdict would result in a payment of approximately $29 million plus post-judgment interest if not overturned or modified on appeal. Elbit has requested an award of approximately $14 million of attorneys’ fees. HNS is contesting Elbit’s claims as inappropriate and unreasonable in light of the court’s decision and prevailing law. On April 27, 2018, HNS filed a notice of appeal to the U.S. Court of Appeals for the Federal Circuit. The parties have briefed the appeal and are awaiting a date for oral arguments. We cannot predict with certainty the outcome of the appeal. As of December 31, 2018 and 2017, we have recorded an accrual of approximately $3 million and $3 million, respectively, with respect to this liability. Any eventual payments made with respect to the ultimate outcome of this matter may be different from our accruals and such differences could be significant. Realtime Data LLC On May 8, 2015, Realtime Data LLC (“Realtime”) filed suit against EchoStar Corporation and our subsidiary HNS in the U.S. District Court for the Eastern District of Texas alleging infringement of U.S. Patent Nos. 7,378,992 (the “992 patent”), entitled “Content Independent Data Compression Method and System;” 7,415,530 (the “530 patent”), entitled “System and Methods for Accelerated Data Storage and Retrieval,” and 8,643,513 (the “513 patent”), entitled “Data Compression System and Methods.” On September 14, 2015, Realtime amended its complaint, additionally alleging infringement of U.S. Patent No. 9,116,908 (the “908 patent”), entitled “System and Methods for Accelerated Data Storage and Retrieval.” On February 14, 2017, Realtime filed a second suit against EchoStar Corporation and our subsidiary HNS in the same District Court, alleging infringement of four additional U.S. Patents, Nos. 7,358,867 (the “867 patent”), entitled “Content Independent Data Compression Method and System;” 8,502,707 (the “707 patent”), entitled “Data Compression Systems and Methods;” 8,717,204 (the “204 patent”), entitled “Methods for Encoding and Decoding Data;” and 9,054,728 (the “728 patent”), entitled “Data Compression System and Methods.” On February 13, 2018, we filed petitions before the USPTO challenging the validity of all claims asserted against us from the 707 patent, as well as one of the asserted claims of the 728 patent. On September 5, 2018, the USPTO declined to institute proceedings for the petition that we had filed against the 728 patent. On September 12, 2018, the USPTO instituted proceedings to review the validity of the asserted claims of the 707 patent. In a stipulation filed on October 24, 2018, Realtime voluntarily elected not to pursue any previously asserted claims from the 992, 530, 513, 908, 867 and 204 patents. Realtime is an entity that seeks to license an acquired patent portfolio without itself practicing any of the claims recited therein. In February 2019, we entered into a settlement agreement with Realtime and the case was dismissed with prejudice. Other In addition to the above actions, we are subject to various other legal proceedings and claims, which arise in the ordinary course of business. As part of our ongoing operations, we are subject to various inspections, audits, inquiries, investigations and similar actions by third parties, as well as by governmental/regulatory authorities responsible for enforcing the laws and regulations to which we may be subject. Further, under the federal False Claims Act, private parties have the right to bring qui tam, or “whistleblower,” suits against companies that submit false claims for payments to, or improperly retain overpayments from, the federal government. Some states have adopted similar state whistleblower and false claims provisions. In addition, we from time to time receive inquiries from federal, state and foreign agencies regarding compliance with various laws and regulations. In our opinion, the amount of ultimate liability with respect to any of these other actions is unlikely to materially affect our financial position, results of operations or cash flows, though the resolutions and outcomes, individually or in the aggregate, could be material to our financial position, operating results or cash flows for any particular period, depending, in part, upon the operating results for such period. We also indemnify our directors, officers and employees for certain liabilities that might arise from the performance of their responsibilities for us. Additionally, in the normal course of its business, we enter into contracts pursuant to which we may make a variety of representations and warranties and indemnify the counterparty for certain losses. Our possible exposure under these arrangements cannot be reasonably estimated as this involves the resolution of claims made, or future claims that may be made, against us or our officers, directors or employees, the outcomes of which are unknown and not currently predictable or estimable.

Segment Reporting [Abstract]
Segment Reporting	SEGMENT REPORTING Operating segments are business components of an enterprise for which separate financial information is available and regularly evaluated by our chief operating decision maker (“CODM”), who is our Chief Executive Officer. We primarily operate in two business segments, Hughes and ESS as described in Note 1 . The primary measure of segment profitability that is reported regularly to our CODM is earnings before interest, taxes, depreciation and amortization, or EBITDA. Our operations also include various corporate departments (primarily Executive, Treasury, Strategic Development, Human Resources, IT, Finance, Real Estate, Accounting and Legal) and other activities that have not been assigned to our operating segments such as costs incurred in certain satellite development programs and other business development activities, and gains or losses from certain of our investments. These activities, costs and income, as well as eliminations of intersegment transactions, are accounted for in Corporate and Other in the tables below or in the reconciliation of EBITDA below. Transactions between segments were not significant for the years ended December 31, 2018 , 2017 and 2016 . Total assets by segment have not been reported herein because the information is not provided to our CODM on a regular basis.

Related Party Transactions [Abstract]
Related Party Transactions	RELATED PARTY TRANSACTIONS EchoStar We and EchoStar, including EchoStar’s other subsidiaries, have agreed that we shall each have the right, but not the obligation, to receive from the other certain shared corporate services, including among other things: treasury, tax, accounting and reporting, risk management, cybersecurity, legal, internal audit, human resources, and information technology. These shared corporate services are generally provided at cost. Effective March 2017, and as a result of the Share Exchange, we implemented a new methodology for determining the cost of these shared corporate services. We and EchoStar, including EchoStar’s other subsidiaries, may each terminate a particular shared corporate service for any reason upon at least 30 days’ notice. We recorded net expenses for shared corporate services received from EchoStar and it other subsidiaries of $16 million , $22 million and $17 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. We also reimburse EchoStar and its other subsidiaries from time to time for amounts paid by EchoStar and its other subsidiaries for costs and expenses attributable to us, and EchoStar and its other subsidiaries similarly reimburse us from time to time for amounts paid by us for costs and expenses attributable to EchoStar and its other subsidiaries. We report net payments under these arrangements in Advances to affiliates, net within current assets and we report net receipts under these arrangements in Advances from affiliates, net within current liabilities in our Consolidated Balance Sheets. No repayment schedule for these net advances has been determined. In addition, we occupy certain office space in buildings owned or leased by EchoStar and its other subsidiaries and pay a portion of the taxes, insurance, utilities and maintenance of the premises in accordance with the percentage of the space we occupy. EchoStar and certain of its other subsidiaries have also provided cash advances to certain of our foreign subsidiaries to fund certain expenditures pursuant to loan agreements that mature in 2021 and 2022. Advances under these agreements bear interest at annual rates ranging from one to three percent, subject to periodic adjustment based on the one-year U.S. LIBOR rate. We report amounts payable under these agreements in Advances from affiliates, net within noncurrent liabilities in our Consolidated Balance Sheets. Contribution of EchoStar XIX Satellite. On February 1, 2017, EchoStar contributed the EchoStar XIX satellite and assigned the related construction contract with the satellite manufacturer to us. We recorded a $349 million increase in Additional paid-in capital, reflecting EchoStar’s $514 million carrying amount of the satellite, including capitalized interest that was previously charged to expense in our consolidated financial statements, less related deferred taxes of $165 million . EchoStar XXI and EchoStar XXIII Launch Facilitation and Operational Control Agreements. As part of applying for launch licenses for the EchoStar XXI and XXIII satellites through the UK Space Agency, we and a subsidiary of EchoStar, EchoStar Operating L.L.C. (“EOC”), entered into agreements in June 2015 and March 2016 to transfer to us EOC’s launch service contracts for the EchoStar XXI and EchoStar XXIII satellites, respectively, and to grant us certain rights to control the in-orbit operations of these satellites. EOC retained ownership of the satellites and agreed to make additional payments to us. for amounts that we are required to pay under both launch service contracts. In 2016, we recorded additions to Other noncurrent assets, net and corresponding increases in Additional paid-in capital in our Consolidated Balance Sheet to reflect EOC’s cumulative payments under the launch service contracts prior to the transfer dates and to reflect EOC’s funding of additional cash payments to the launch service provider. The EchoStar XXIII and the EchoStar XXI satellites were successfully launched in March 2017 and June 2017, respectively. We recorded decreases in Other noncurrent assets, net and Additional paid-in capital of $62 million and $83 million , respectively, representing the carrying amounts of the launch service contracts at the time of launch to reflect the consumption of the contracts’ economic benefits by EOC, the owner of the satellites. Share Exchange. Prior to consummation of the Share Exchange, EchoStar was required to complete steps necessary for the transferring of certain assets and liabilities to DISH and certain of its subsidiaries. As part of these steps, subsidiaries of EchoStar that, prior to the consummation of the Share Exchange, owned EchoStar’s business of providing online video delivery and satellite video delivery for broadcasters and pay-TV operators, including satellite uplinking/downlinking, transmission services, signal processing, conditional access management and other services and related assets and liabilities were contributed to one of our subsidiaries in consideration for additional shares of HSS’ common stock that were then issued to a subsidiary of EchoStar. Certain data center assets that were included in the contribution of certain assets and liabilities to one of our subsidiaries were not included in the Share Exchange and continue to be owned by us and are pledged as collateral to support our obligations under the indentures relating to our Secured Notes. EchoStar Mobile Limited Service Agreements . We provide services and lease equipment to support the business of EchoStar Mobile Limited, a subsidiary of EchoStar that is licensed by the European Union and its member states (“EU”) to provide mobile satellite services and complementary ground component services covering the entire EU using S-band spectrum. Generally, the amounts EchoStar’s subsidiaries pay for these services are based on cost plus a fixed margin. We have converted the receivables for certain of these services into loans, bearing an annual interest rate of 5% , that mature in 2023. We recorded revenue in Services and other revenue - other of $19 million and $3 million for the year ended December 31, 2018 and 2017 , respectively, related to these services. DBS Transponder Lease. EchoStar leases satellite capacity from us on eight DBS transponders on the QuetzSat-1 satellite through November 2021, after which EchoStar has certain options to renew the agreement on a year-to year basis through the end of life of the QuetzSat-1 satellite. We recorded revenue in connection with this agreement of approximately $23 million for each of the years ended December 31, 2018 , 2017 and 2016 . As of December 31, 2018 and 2017 , we had related trade accounts receivable of approximately $6 million and $8 million , respectively. Construction Management Services for EchoStar XXIV satellite. In August 2017, a subsidiary of EchoStar entered into a contract with Space Systems Loral, LLC for the design and construction of the EchoStar XXIV satellite, a new, next-generation, high throughput geostationary satellite, with a planned 2021 launch. We provide construction management services to EchoStar’s subsidiary for the construction of the EchoStar XXIV satellite. We charged EchoStar and reduced our operating expenses by the costs of such services of $1 million and $0.4 million for the years ended December 31, 2018 and 2017 , respectively. DISH Network Following the Spin-off, EchoStar and DISH have operated as separate publicly-traded companies. In addition, prior to the consummation of the Share Exchange in February 2017, DISH Network owned the Tracking Stock, which represented an aggregate 80.0% economic interest in the residential retail satellite broadband business of our Hughes segment. Following the consummation of the Share Exchange, the Tracking Stock was retired. A substantial majority of the voting power of the shares of each of EchoStar and DISH is owned beneficially by Charles W. Ergen, our Chairman, and by certain entities established by Mr. Ergen for the benefit of his family. In connection with and following both the Spin-off and the Share Exchange, EchoStar, we and certain other of EchoStar’s subsidiaries and DISH and certain of its subsidiaries entered into certain agreements pursuant to which we and EchoStar and its other subsidiaries obtain certain products, services and rights from DISH Network; DISH Network obtains certain products, services and rights from us and EchoStar and its other subsidiaries and such entities indemnify each other against certain liabilities arising from the respective businesses. We and/or EchoStar also may enter into additional agreements with DISH Network in the future. Generally, the amounts we and/or EchoStar or DISH Network pay for products and services provided under the agreements are based on cost plus a fixed margin (unless noted differently below), which varies depending on the nature of the products and services provided. The following is a summary of the terms of our principal agreements with DISH Network that may have an impact on our financial condition and results of operations. Services and Other Revenue — DISH Network Satellite Capacity Leased to DISH Network. We have entered into certain agreements to lease satellite capacity pursuant to which we provide satellite services to DISH Network on certain satellites owned or leased by us. The fees for the services provided under these agreements depend, among other things, upon the orbital location of the applicable satellite, the number of transponders that are providing services on the applicable satellite and the length of the service arrangements. The terms of each service arrangement is set forth below: EchoStar VII, EchoStar X, EchoStar XI and EchoStar XIV . In March 2014, as part of the Satellite and Tracking Stock Transaction, described below in Other Agreements - DISH Network, we began leasing certain satellite capacity to DISH Network on the EchoStar VII, EchoStar X, EchoStar XI and EchoStar XIV satellites. These agreements to lease satellite capacity generally terminate upon the earlier of: (i) the end of life of the satellite; (ii) the date the satellite fails; or (iii) a certain date, which depends upon, among other things, the estimated useful life of the satellite. DISH Network generally has the option to renew each agreement to lease satellite capacity on a year-to-year basis through the end of the respective satellite’s life. There can be no assurance that any options to renew such agreements will be exercised. The agreement to lease satellite capacity on the EchoStar VII satellite expired at the end of June 2018. EchoStar IX. Effective January 2008, DISH Network began leasing satellite capacity from us on the EchoStar IX satellite. Subject to availability, DISH Network generally has the right to continue leasing satellite capacity from us on the EchoStar IX satellite on a month-to-month basis. EchoStar XII. DISH Network leased satellite capacity from us on the EchoStar XII satellite. The agreement to lease satellite capacity expired at the end of September 2017. EchoStar XVI. In December 2009, we entered into an initial ten -year agreement to lease satellite capacity to DISH Network, pursuant to which DISH Network has leased satellite capacity from us on the EchoStar XVI satellite since January 2013. Effective December 2012, we and DISH Network amended the agreement to, among other things, change the initial term to generally expire upon the earlier of: (i) the end-of-life or replacement of the satellite; (ii) the date the satellite fails; (iii) the date the transponder(s) on which service is being provided under the agreement fails; or (iv) four years following the actual service commencement date. In July 2016, we and DISH Network further amended the agreement to, among other things, extend the initial term by one additional year through January 2018 and to reduce the term of the first renewal option by one year. In May 2017, DISH Network renewed the agreement through January 2023. DISH Network has the option to renew for an additional five -year period prior to expiration of the current term. There can be no assurance that such option to renew this agreement will be exercised. In the event that DISH Network does not exercise its five -year renewal option, DISH Network has the option to purchase the EchoStar XVI satellite for a certain price. If DISH Network does not elect to purchase the EchoStar XVI satellite at that time, we may sell the EchoStar XVI satellite to a third party and DISH Network is required to pay us a certain amount in the event we are not able to sell the EchoStar XVI satellite for more than a certain amount. We and DISH Network have amended the agreement to allow DISH Network to place and use certain satellites at the 61.5 degree west longitude orbital location. Nimiq 5 Agreement. In September 2009, we entered into a fifteen -year agreement with Telesat Canada to lease satellite capacity from Telesat Canada on all 32 direct broadcast satellite (“DBS”) transponders on the Nimiq 5 satellite at the 72.7 degree west longitude orbital location (the “Telesat Transponder Agreement”). In September 2009, we also entered into an agreement with DISH Network, pursuant to which DISH Network leases satellite capacity from us on all 32 of the DBS transponders covered by the Telesat Transponder Agreement (the “DISH Nimiq 5 Agreement”). Under the terms of the DISH Nimiq 5 Agreement, DISH Network makes certain monthly payments to us that commenced in September 2009, when the Nimiq 5 satellite was placed into service, and continue through the service term. Unless earlier terminated under the terms and conditions of the DISH Nimiq 5 Agreement, the service term will expire in October 2019. Upon expiration of the initial term, DISH Network has the option to renew the DISH Nimiq 5 Agreement on a year-to-year basis through the end of life of the Nimiq 5 satellite. Upon in-orbit failure or end of life of the Nimiq 5 satellite, and in certain other circumstances, DISH Network has certain rights to lease satellite capacity from us on a replacement satellite. There can be no assurance that any options to renew the DISH Nimiq 5 Agreement will be exercised or that DISH Network will exercise its option to lease satellite capacity on a replacement satellite. QuetzSat-1 Agreement. In November 2008, we entered into a ten -year agreement to lease satellite capacity from SES Latin America, which provides, among other things, for the provision by SES Latin America to us of leased satellite capacity on 32 DBS transponders on the QuetzSat-1 satellite. Concurrently, in 2008, we entered into an agreement pursuant to which DISH Network leases from us satellite capacity on 24 of the DBS transponders on the QuetzSat-1 satellite. The QuetzSat-1 satellite was launched in September 2011 and was placed into service in November 2011 at the 67.1 degree west longitude orbital location. In January 2013, the QuetzSat-1 satellite was moved to the 77 degree west longitude orbital location. In February 2013, EchoStar and DISH Network entered into an agreement pursuant to which EchoStar leases back from DISH Network certain satellite capacity on five DBS transponders on the QuetzSat-1 satellite through November 2021, unless extended or earlier terminated under the terms and conditions of our agreement. Under the terms of our contractual arrangements with DISH Network, we began leasing satellite capacity to DISH Network on the QuetzSat-1 satellite in February 2013 and will continue leasing such capacity through November 2021, unless extended or earlier terminated under the terms and conditions of our agreement with DISH Network for the QuetzSat-1 satellite. Upon expiration of the initial service term, DISH Network has the option to renew the agreement for the QuetzSat-1 satellite on a year-to-year basis through the end of life of the QuetzSat-1 satellite. Upon an in-orbit failure or end of life of the QuetzSat-1 satellite, and in certain other circumstances, DISH Network has certain rights to lease satellite capacity from us on a replacement satellite. There can be no assurance that any options to renew this agreement will be exercised or that DISH Network will exercise its option to lease satellite capacity on a replacement satellite. 103 Degree Orbital Location/SES-3. In May 2012, we entered into a spectrum development agreement (the “103 Spectrum Development Agreement”) with Ciel Satellite Holdings Inc. (“Ciel”) to develop certain spectrum rights at the 103 degree west longitude orbital location (the “103 Spectrum Rights”). In June 2013, we and DISH Network entered into a spectrum development agreement (the “DISH 103 Spectrum Development Agreement”) pursuant to which DISH Network may use and develop the 103 Spectrum Rights. Effective in March 2018, DISH Network exercised its right to terminate the DISH 103 Spectrum Development Agreement and we exercised our right to terminate the 103 Spectrum Development Agreement. In connection with the 103 Spectrum Development Agreement, in May 2012, we also entered into a ten -year agreement with Ciel pursuant to which we leased certain satellite capacity from Ciel on the SES-3 satellite at the 103 degree west longitude orbital location (the “Ciel 103 Agreement”). In June 2013, we and DISH Network entered into an agreement pursuant to which DISH Network leased certain satellite capacity from us on the SES-3 satellite (the “DISH 103 Agreement”). Under the terms of the DISH 103 Agreement, DISH Network made certain monthly payments to us through the service term. Effective in March 2018, DISH Network exercised its right to terminate the DISH 103 Agreement and we exercised our right to terminate the Ciel 103 Agreement. TT&C Agreement. Effective January 2012, we entered into a TT&C agreement pursuant to which we provided TT&C services to DISH Network for a period ending in December 2016 (the “TT&C Agreement”). We and DISH Network have amended the TT&C Agreement over time to, among other things, extend the term through February 2023. The fees for services provided under the TT&C Agreement are calculated at either: (i) a fixed fee or (ii) cost plus a fixed margin, which will vary depending on the nature of the services provided. DISH Network is able to terminate the TT&C Agreement for any reason upon 12 months’ notice. Effective March 2014, we provide TT&C services for the D-1 and EchoStar XV satellites; however, for the period that we received satellite services on the EchoStar XV satellite from DISH Network, we waived the fees for the TT&C services on the EchoStar XV satellite. Effective August 2016, we provide TT&C services to DISH Network for the EchoStar XVIII satellite. Real Estate Lease . Prior to the Share Exchange, EchoStar leased to DISH Network certain space at 530 EchoStar Drive, Cheyenne, Wyoming. In connection with the Share Exchange, EchoStar transferred ownership of a portion of this property to DISH Network and contributed a portion to us and we amended the agreement to (i) terminate the lease for the transferred space and (ii) provide for a continued lease to DISH Network of the portion of the property contributed to us for a period ending in December 2031. The rent on a per square foot basis for the lease is comparable to per square foot rental rates of similar commercial property in the same geographic area at the time of the lease, and DISH Network is responsible for its portion of the taxes, insurance, utilities and maintenance of the premises. After December 2031, this agreement may be converted by mutual consent to a month-to-month lease agreement with either party having the right to terminate upon 30 days’ notice. TerreStar Agreement. In March 2012, DISH Network completed its acquisition of substantially all the assets of TerreStar Networks Inc. (“TerreStar”). Prior to DISH Network’s acquisition of substantially all the assets of TerreStar and our completion of the Hughes Acquisition, TerreStar and HNS entered into various agreements pursuant to which we provide, among other things, warranty, operations and maintenance and hosting services for TerreStar’s ground-based communications equipment. In December 2017, we and DISH Network amended these agreements, effective as of January 1, 2018, to reduce certain pricing terms through December 31, 2023 and to modify certain termination provisions.

Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation We consolidate all entities in which we have a controlling financial interest. We are deemed to have a controlling financial interest in variable interest entities where we are the primary beneficiary. We are deemed to have a controlling financial interest in other entities when we own more than 50% of the outstanding voting shares and other shareholders do not have substantive rights to participate in management. For entities we control but do not wholly own, we record a noncontrolling interest within shareholders’ equity for the portion of the entity’s equity attributed to the noncontrolling ownership interests. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the U.S. (“GAAP”) requires us to make certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the balance sheets, the reported amounts of revenue and expense for each reporting period and certain information disclosed in the notes to our financial statements. Estimates are used in accounting for, among other things, (i) amortization periods for deferred contract acquisition costs, (ii) inputs used to recognize revenue over time, (iii) allowances for doubtful accounts, (iv) warranty obligations, (v) self-insurance obligations, (vi) deferred taxes and related valuation allowances, (vii) uncertain tax positions, (viii) loss contingencies, (ix) fair value of financial instruments, (x) fair value of EchoStar’s stock-based compensation awards, (xi) fair value of assets and liabilities acquired in business combinations, (xii) lease classifications, (xiii) asset impairment testing and (xiv) useful lives and methods for depreciation and amortization of long-lived assets. We base our estimates and assumptions on historical experience, observable market inputs and on various other factors that we believe to be relevant under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results may differ from previously estimated amounts, and such differences may be material to our financial statements. Additionally, changing economic conditions may increase the inherent uncertainty in the estimates and assumptions indicated above. We review our estimates and assumptions periodically and the effects of revisions thereto are reflected in the period they occur or prospectively if the revised estimate affects future periods.
Fair Value Measurements	Fair Value Measurements We determine fair value based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. Market or observable inputs are the preferred source of values, followed by unobservable inputs or assumptions based on hypothetical transactions in the absence of market inputs. We utilize the highest level of inputs available according to the following hierarchy in determining fair value • Level 1 - Defined as observable inputs being quoted prices in active markets for identical assets; • Level 2 - Defined as observable inputs other than quoted prices included in Level 1, including quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and • Level 3 - Defined as unobservable inputs for which little or no market data exists, consistent with characteristics of the asset or liability that would be considered by market participants in a transaction to purchase or sell the asset or liability. Fair values of our marketable investment securities are based on a variety of observable market inputs. For our investments in publicly traded equity securities and U.S. government securities, fair value ordinarily is determined based on Level 1 measurements that reflect quoted prices for identical securities in active markets. Fair values of our investments in other marketable debt securities are generally based on Level 2 measurements, as the markets for such debt securities are less active. We consider trades of identical debt securities on or near the measurement date as a strong indication of fair value and matrix pricing techniques that consider par value, coupon rate, credit quality, maturity and other relevant features may also be used to determine fair value of our investments in marketable debt securities. Fair values for our outstanding debt (see Note 10 ) are based on quoted market prices in less active markets and are categorized as Level 2 measurements. Additionally, we use fair value measurements from time to time in connection with asset impairment testing and the assignment of purchase consideration to assets and liabilities of acquired companies. Those fair value measurements typically include significant unobservable inputs and are categorized within Level 3 of the fair value hierarchy. Transfers between levels in the fair value hierarchy are considered to occur at the beginning of the quarterly accounting period. There were no transfers between levels for each of the years ended December 31, 2018 and 2017 . As of December 31, 2018 and 2017 , the carrying amounts of our cash and cash equivalents, trade and other receivables, net of allowance for doubtful accounts, accounts payable and accrued liabilities were equal to or approximated their fair value due to their short-term nature or proximity to current market rates.
Revenue Recognition	Revenue Recognition Overview We account for our sales and services revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“Topic 606”) , which we adopted on January 1, 2018, using the modified retrospective approach to contracts not completed as of the adoption date. Topic 606 provides a five-step revenue recognition model that we apply to our customer contracts. Under this model we (i) identify the contract with the customer, (ii) identify our performance obligations in the contract, (iii) determine the transaction price for the contract, (iv) allocate the transaction price to our performance obligations and (v) recognize revenue when or as we satisfy our performance obligations. Revenue is recognized upon transfer of control of the promised goods or our performance of the services to our customers in an amount that reflects the consideration we expect to receive in exchange for those goods or services. We enter into contracts that may include various combinations of products and services, which are generally distinct and accounted for as separate performance obligations. Additionally, a significant portion of our revenue is derived from leases of property and equipment that is reported in Services and other revenue - other and Services and other revenue - DISH Network in our Consolidated Statements of Operations and Comprehensive Income (Loss). Certain of our customer contracts contain embedded equipment leases, which we separate from non-lease components of the contract based on the relative standalone selling prices of the lease and non-lease components. Hughes Our Hughes segment provides various communication and networking services to consumer and enterprise customers in both domestic and international markets. Our service contracts typically obligate us to provide substantially the same services on a recurring basis in exchange for fixed recurring fees over the term of the contract. We satisfy such performance obligations over time and recognize revenue ratably as services are rendered over the service period. Certain of our contracts with service obligations provide for fees based on usage, capacity or volume. We satisfy these performance obligations and recognize the related revenue at the point in time or over the period when the services are rendered. Our Hughes segment also sells and leases communications equipment to its customers. Revenue from equipment sales generally is recognized upon shipment of the equipment. Our equipment sales contracts typically include standard product warranties, but generally do not provide for returns or refunds. Revenue for extended warranties is recognized ratably over the extended warranty period. For contracts with multiple performance obligations, we typically allocate the contract’s transaction price to each performance obligation based on their relative standalone selling prices. When the standalone selling price is not observable, our primary method used to estimate standalone selling price is the expected cost plus a margin. Our contracts generally require customer payments to be made at or shortly after the time we transfer control of goods or perform the services. In addition to equipment and service offerings, our Hughes segment also enters into long-term contracts to design, develop, construct and install complex telecommunication networks to customers in its enterprise and mobile satellite systems markets. Revenue from such contracts is generally recognized over time at a measure of progress that depicts the transfer of control of the goods or services to the customer. Depending on the nature of the arrangement, we measure progress toward contract completion using an appropriate input method or output method. Under the input method, we recognize the transaction price as revenue based on the ratio of costs incurred to estimated total costs at completion. Under the output method, revenue and cost of sales are recognized as products are delivered based on the expected profit for the entire agreement. Profit margins on long-term contracts generally are based on estimates of revenue and costs at completion. We review and revise our estimates periodically and recognize related adjustments in the period in which the revisions are made. Estimated losses on contracts are recorded in the period in which they are identified. We generally receive interim payments as work progresses, although for some contracts, we may be entitled to receive an advance payment. ESS Our ESS segment provides satellite operations through leasing arrangements and satellite services on a full-time and/or occasional-use basis to DISH Network and Dish Mexico, as well as government service providers, internet service providers, broadcast news organizations, content providers and private enterprise customers. Our ESS segment also provides telemetry, tracking and control (“TT&C”) services for satellites owned by DISH Network and technical consulting services that are billed by the hour. Generally, our service contracts with customers contain a single performance obligation and therefore there is no need to allocate the transaction price. We transfer control and recognize revenue for satellite services at the point in time or over the period when the services are rendered. Other Sales and Value Added Taxes, Universal Service Fees and other taxes that we collect concurrent with revenue producing activities are excluded from revenue. Shipping and handling costs associated with outbound freight are accounted for as a fulfillment cost after control over a product has transferred to the customer and are included in Cost of sales - equipment in our Consolidated Statements of Operations and Comprehensive Income (Loss) at the time of shipment. Contract Balances Trade Accounts Receivable Trade accounts receivable includes amounts billed and currently due from customers and represents our unconditional rights to consideration arising from our performance under our customer contracts. Trade accounts receivable also includes amounts due from customers under our leasing arrangements. We make ongoing estimates relating to the collectibility of our trade accounts receivable and maintain an allowance for estimated losses resulting from the inability of our customers to make the required payments. In determining the amount of the allowance, we consider historical levels of credit losses and make judgments about the creditworthiness of our customers based on ongoing credit evaluations. Past due trade accounts receivable balances are written off when our internal collection efforts have been unsuccessful. Bad debt expense related to our trade accounts receivable and other contract assets is included in Selling, general and administrative expenses in our Consolidated Statements of Operations and Comprehensive Income (Loss). Contract Assets and Contract Liabilities Contract assets represent revenue that we have recognized in advance of billing the customer and are included in Trade accounts receivable and contract assets, net or Other noncurrent assets, net in our Consolidated Balance Sheets based on the expected timing of customer payment. Our contract assets include amounts that we referred to as Contracts in Process in prior periods. Our contract assets typically relate to our long-term contracts where we recognize revenue using the cost-based input method and the revenue recognized exceeds the amount billed to the customer. Contract liabilities consist of advance payments and billings in excess of revenue recognized under customer contracts and are included in Contract liabilities or Other noncurrent liabilities in our Consolidated Balance Sheets based on the timing of when we expect to recognize revenue. Contract liabilities include amounts that we referred to as deferred revenue in prior periods. We recognize contract liabilities as revenue after all revenue recognition criteria have been met. Contract Acquisition and Fulfillment Costs Contract Acquisition Costs Our contract acquisition costs represent incremental direct costs of obtaining a contract and consist primarily of sales incentives paid to employees and third-party representatives. When we determine that our contract acquisition costs are recoverable, we defer and amortize the costs over the contract term, or over the estimated life of the customer relationship if anticipated renewals are expected and the incentives payable upon renewal are not commensurate with the initial incentive. We amortize contract acquisition costs in proportion to the revenue to which the costs relate. We expense sales incentives as incurred if the expected amortization period is one year or less. Unamortized contract acquisition costs are included in Other noncurrent assets, net in our Consolidated Balance Sheets and related amortization expense is included in Selling, general and administrative expenses in our Consolidated Statements of Operations and Comprehensive Income (Loss). Contract Fulfillment Costs We recognize costs to fulfill a contract as an asset when the costs relate directly to a specific contract, the costs generate or enhance our resources that will be used in satisfying future performance obligations and the costs are expected to be recovered. We may incur such costs on certain contracts that require initial setup activities in advance of the transfer of goods or services to the customer. We amortize these costs in proportion to the revenue to which the costs relate. Unamortized contract fulfillment costs are included in Other noncurrent assets, net in our Consolidated Balance Sheets and related amortization expense is included in Cost of sales - services and other
Foreign Currency	Foreign Currency The functional currency for certain of our foreign operations is determined to be the local currency. Accordingly, we translate assets and liabilities of these foreign entities from their local currencies to U.S. dollars using period-end exchange rates and translate income and expense accounts at monthly average rates. The resulting translation adjustments are reported in other comprehensive income (loss) as Foreign currency translation adjustments in our Consolidated Statements of Operations and Comprehensive Income (Loss) . Except in certain uncommon circumstances, we have not recorded deferred income taxes related to our foreign currency translation adjustments. Gains and losses resulting from re-measurement of monetary assets and liabilities denominated in foreign currencies into the functional currency are recognized in Other, net in our Consolidated Statements of Operations and Comprehensive Income (Loss).
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all liquid investments purchased with an original maturity of 90 days or less to be cash equivalents. Cash equivalents as of December 31, 2018 and 2017 primarily consisted of commercial paper, government bonds, corporate notes, and money market funds. The amortized cost of these investments approximates their fair value.
Inventory	Inventory Inventory is stated at the lower of cost, determined using the first-in, first-out (“FIFO”) method, or net realizable value. Cost of inventory consists primarily of materials, direct labor and indirect overhead incurred in the procurement and manufacturing of our products. We use standard costing methodologies in determining the cost of certain of our finished goods and work-in-process inventories. We determine net realizable value using our best estimates of future use or recovery, considering the aging and composition of inventory balances, the effects of technological and/or design changes, forecasted future product demand based on firm or near-firm customer orders, and alternative means of disposition of excess or obsolete items. We recognize losses within operating income when we determine that the cost of inventory and commitments to purchase inventory exceed net realizable value.
Capitalized Software Costs	Capitalized Software Costs Internal-Use Software Costs related to the procurement and development of software for internal-use are capitalized and amortized using the straight-line method over the estimated useful life of the software, not in excess of five years . Capitalized costs of internal-use software are included in Property and equipment, net in our Consolidated Balance Sheets. Externally Marketed Software Costs related to the procurement and development of software for externally marketed software are capitalized and amortized using the straight-line method over the estimated useful life of the software, not in excess of five years . Capitalized costs of externally marketed software are included in Other noncurrent assets, net in our Consolidated Balance Sheets. Externally marketed software generally is installed in the equipment we sell or lease to customers. We conduct software program reviews for externally marketed capitalized software costs at least annually, or as events and circumstances warrant such a review, to determine if capitalized software development costs are recoverable and to ensure that costs associated with programs that are no longer generating revenue are expensed.
Marketable Investment Securities	Marketable Investment Securities Our marketable investment securities portfolio consists of investments in debt and equity instruments with readily determinable fair values. Debt Securities We classify all of our debt securities as available for sale based on our investment strategy for the securities. Generally, we recognize periodic changes in the difference between fair value and amortized cost in Unrealized gains on available-for-sale securities and other in our Consolidated Statements of Operations and Comprehensive Income (Loss). Realized gains and losses upon sales of debt securities are reclassified from other comprehensive income (loss) and recognized on the trade date in Gains and losses on investments, net in our Consolidated Statements of Operations and Comprehensive Income (Loss). We use the FIFO method to determine the cost basis on sales of debt securities. Interest income from debt securities is reported in Interest income in our Consolidated Statements of Operations and Comprehensive Income (Loss). We could realize proceeds from certain investments prior to their contractual maturity if we sell these securities before such maturity. We evaluate our available-for-sale debt securities portfolio periodically to determine whether declines in the fair value of these securities are other-than-temporary. Our evaluation considers, among other things, the length of time and the extent to which the fair value of such security has been lower than amortized cost, market and company-specific factors related to the security and our intent and ability to hold the investment to maturity or when it recovers its value. We generally consider a decline to be other-than-temporary when: (i) we intend to sell the security, (ii) it is more likely than not that we will be required to sell the security before maturity or when it recovers its value, or (iii) we do not expect to recover the amortized cost of the security at maturity. Declines in the fair value of available-for-sale debt securities that are determined to be other-than-temporary are reclassified from other comprehensive income (loss) and recognized in Net income , in our Consolidated Statements of Operations and Comprehensive Income (Loss), thus establishing a new cost basis for the investment. Additionally, from time to time we make strategic investments in corporate debt securities. We may elect to account for these investments using the fair value option when it reduces accounting complexity. When we have made this election, we recognize periodic changes in fair value of these investments in Gains (losses) on investments, net in our Consolidated Statements of Operations and Comprehensive Income (Loss). Interest income from these securities is reported in Interest income in our Consolidated Statements of Operations and Comprehensive Income (Loss). Equity Securities Prior to January 1, 2018, we classified our marketable equity securities as available-for-sale or trading securities, depending on our investment strategy for the securities. For available-for-sale securities, we recognized periodic changes in the difference between fair value and cost in Unrealized gains (losses) on available-for-sale securities and other in our Consolidated Statements of Operations and Comprehensive Income (Loss). Realized gains and losses upon sale of available-for-sale securities were reclassified from other comprehensive income (loss) and recognized on the trade date in Gains (losses) on investments, net in our Consolidated Statements of Operations and Comprehensive Income (Loss). We used the FIFO method to determine the cost basis on sales of available-for-sale securities. For trading securities, we recognized periodic changes in the fair value of the securities in Gains and losses on investments, net in our Consolidated Statements of Operations and Comprehensive Income (Loss). Effective January 1, 2018, we adopted Accounting Standards Update (“ASU”) No. 2016-01, Financial Instruments (the “New Investment Standard”) , which established new requirements for investments in equity securities in ASC Topic 321, Investments - Equity Securities . Accordingly, beginning in 2018, we recognize periodic changes in the fair value of all of our equity securities with a readily determinable fair value that are not accounted for using the equity method in Gains and losses on investments, net in our Consolidated Statements of Operations and Comprehensive Income (Loss). We recognize dividend income on equity securities on the ex-dividend date and report such income in Other, net
Investments in Unconsolidated Entities - Cost and Equity Method	Investments in Unconsolidated Entities Our investments in unconsolidated entities consist of investments in equity securities that are not publicly traded and do not have readily determinable fair values. Equity Method We use the equity method to account for investments when we have the ability to exercise significant influence on the operating decisions of the investee. Such investments in unconsolidated entities are initially recorded at cost and subsequently adjusted for our proportionate share of the net earnings or loss of the investee, which is reported in Equity in earnings of unconsolidated affiliate in our Consolidated Statements of Operations and Comprehensive Income (Loss). The carrying amount of such investments may include a component of goodwill if the cost of our investment exceeds the fair value of the underlying identifiable assets and liabilities of the investee. Dividends received from equity method investees reduce the carrying amount of the investment. We defer, to the extent of our ownership interest in the investee, recognition of intra-entity profits on sales of equipment to the investee until the investee has charged the cost of the equipment to expense in a subsequent sale to a third party or through depreciation. In these circumstances, we report the gross amounts of revenue and cost of sales in the Consolidated Statements of Operations and Comprehensive Income (Loss) and include the intra-entity profit eliminations within Equity in earnings of unconsolidated affiliate . Other Investments Prior to January 1, 2018, we accounted for other investments without a readily determinable fair value using the cost method. In connection with our adoption of the New Investment Standard as of January 1, 2018, we have elected to measure such investments at cost, adjusted for changes resulting from impairments and observable price changes in orderly transactions for identical or similar securities of the same issuer. We consider information in periodic financial statements and other documentation provided by our investees and we may make inquiries of investee management to determine whether observable price changes have occurred. Impairment Considerations We evaluate all of our investments in unconsolidated entities periodically to determine whether events or changes in circumstances have occurred that may have a significant adverse effect on the fair value of the investment. As part of our evaluation, we review available information such as business plans and current financial statements of these companies for factors that may indicate an impairment of our investments. Such factors may include, but are not limited to, unprofitable operations, negative cash flow, material litigation, violations of debt covenants, bankruptcy and changes in business strategy. When we determine that an investment is impaired, we adjust the carrying amount of the investment to its estimated fair value and recognize the impairment loss in Gains and losses on investments, net
Property and Equipment	Property and Equipment Property and equipment is stated at cost, less accumulated depreciation. Depreciation is recorded on a straight-line basis over lives ranging from one to 40 years . The cost of our satellites includes construction costs, including the present value of in-orbit incentives payable to the satellite manufacturer, launch costs, capitalized interest, and related insurance premiums. Repair and maintenance costs are charged to expense when incurred. Costs of renewals and betterments are capitalized.
Impairment of Long-lived Assets	Impairment of Long-lived Assets We review our long-lived assets for recoverability whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. The evaluation is performed at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. For assets held and used in operations, the asset is not recoverable if the carrying amount of the asset exceeds its undiscounted estimated future net cash flows. When an asset is not recoverable, we adjust the carrying amount of such asset to its estimated fair value and recognize the impairment loss in Net Income in our Consolidated Statements of Operations. Assets to be disposed of by sale are reported at the lower of the carrying amount or fair value less costs to sell.
Goodwill	Goodwill Goodwill represents the excess of the cost of acquired businesses over the estimated fair value assigned to the identifiable assets acquired and liabilities assumed. We do not amortize goodwill, but test goodwill for impairment annually, or more frequently if circumstances indicate impairment may exist. Our goodwill as of December 31, 2018 and 2017 is assigned to reporting units of our Hughes segment. We test such goodwill for impairment in the second fiscal quarter. The goodwill impairment test involves a comparison of the fair value of a reporting unit with its carrying amount, including goodwill. We typically estimate fair value of reporting units using discounted cash flow techniques, which includes significant assumptions about prospective financial information, terminal value and discount rates (Level 3 inputs). If the reporting unit’s carrying amount exceeds its estimated fair value, we recognize an impairment loss equal to such excess, not to exceed the carrying amount of goodwill. We may bypass the quantitative goodwill impairment test if we determine, based on a qualitative assessment, that it is more likely than not that the fair value of a reporting unit exceeds its carrying amount including goodwill.
Regulatory Authorizations and Other Intangible Assets	Regulatory Authorizations and Other Intangible Assets At acquisition and periodically thereafter, we evaluate our intangible assets to determine whether their useful lives are finite or indefinite. We consider our intangible assets to have indefinite lives when no significant legal, regulatory, contractual, competitive, economic, or other factors limit their useful lives. Intangible assets that have finite lives are amortized over their estimated useful lives, ranging from approximately one to 20 years . When we expect to incur significant costs to renew or extend finite-lived intangible assets, we amortize the total initial and estimated renewal costs over the combined initial and expected renewal terms. In such instances, actual renewal costs are capitalized when they are incurred. We test intangible assets with finite lives for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable (see Impairment of Long-lived Assets above). We do not amortize our indefinite-lived intangible assets, but test those assets for impairment annually or more frequently if circumstances indicate that it is more likely than not that the asset may be impaired. Costs incurred to maintain or renew indefinite-lived intangible assets are expensed as incurred. Our indefinite-lived intangible assets include Federal Communications Commission (“FCC”) authorizations and certain other contractual or regulatory rights to use spectrum at specified orbital locations (collectively “Regulatory Authorizations”). We have determined that our FCC authorizations generally have indefinite useful lives due to the following: • FCC authorizations are non-depleting assets; • renewal satellite applications generally are authorized by the FCC subject to certain conditions, without substantial cost under a stable regulatory, legislative, and legal environment; • expenditures required to maintain the authorization are not significant; and • we intend to use these authorizations indefinitely.
Debt Issuance Costs	Debt Issuance Costs Costs of issuing debt generally are deferred and amortized utilizing the effective interest method with amortization included in Interest expense, net of amounts capitalized
Income Taxes	Income Taxes We are included in the consolidated federal income tax return of EchoStar. We recognize a provision or benefit for income taxes currently payable or receivable and for income tax amounts deferred to future periods based upon a separate return allocation method which results in income tax expense that approximates the expense that would result if we were a stand-alone entity. Deferred tax assets and liabilities are recorded based on enacted tax laws for the estimated future tax effects of differences that exist between the financial reporting carrying amount and tax basis of assets and liabilities. Deferred tax assets are offset by valuation allowances when we determine it is more likely than not that such deferred tax assets will not be realized in the foreseeable future. We determine deferred tax assets and liabilities separately for each taxing jurisdiction and report the net amount for each jurisdiction as a noncurrent asset or liability in our Consolidated Balance Sheets . From time to time, we engage in transactions where the income tax consequences are uncertain. We recognize tax benefits when, in management’s judgment, a tax filing position is more likely than not to be sustained if challenged by the tax authorities. For tax positions that meet the more-likely-than-not threshold, we may not recognize a portion of a tax benefit depending on management’s assessment of how the tax position will ultimately be settled. Unrecognized tax benefits generally are netted against the deferred tax assets associated with our net operating loss carryforwards. We adjust our estimates periodically based on ongoing examinations by and settlements with various taxing authorities, as well as changes in tax laws, regulations and precedent. We classify interest and penalties, if any, associated with our unrecognized tax benefits as a component of income tax provision or benefit.
Cost of Sales - Equipment and Services	Cost of Sales - Services and Equipment Cost of sales - services and other in our Consolidated Statements of Operations and Comprehensive Income (Loss) primarily consists of costs of satellite capacity and services, hub infrastructure, customer care, wireline and wireless capacity, and direct labor costs associated with the services provided. Cost of sales - services and other generally are charged to expense as incurred. Cost of sales - equipment in our Consolidated Statements of Operations and Comprehensive Income (Loss) primarily consists of inventory costs, including freight and royalties. Cost of sales - equipment
Research and Development	Research and Development Costs incurred in research and development activities are generally expensed as incurred. A significant portion of our research and development costs are incurred in connection with the specific requirements of a customer’s order. In such instances, the amounts for these customer funded development efforts are included in Cost of sales-equipment in our Consolidated Statements of Operations and Comprehensive Income (Loss).
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred and are included in Selling, general and administrative expenses
Recently Adopted and Not Yet Adopted Accounting Pronouncements	Restricted Cash and Cash Equivalents ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash requires restricted cash and restricted cash equivalents to be included with cash and cash equivalents in our Statement of Cash Flows. We adopted ASU No. 2016-18 as of January 1, 2018. As a result, the beginning and ending balances of cash and cash equivalents presented in our Consolidated Statements of Cash Flows include amounts for restricted cash and cash equivalents, which historically were not included in such balances, and receipts and payments of restricted cash and cash equivalents, exclusive of transfers to and from unrestricted accounts, are reported in our Consolidated Statements of Cash Flows. The adoption of this accounting standard did not have a material impact on our Statements of Cash Flows and related disclosures. Leases In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This standard requires lessees to recognize assets and liabilities for all leases with lease terms greater than 12 months, including leases classified as operating leases. The standard also modifies the definition of a lease and the criteria for classifying leases as operating, finance or sales-type leases and requires certain additional disclosures. ASU No. 2016-02 is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. The new standard, as amended in July 2018, may be applied either on a modified retrospective basis or prospectively as of the adoption date without restating prior periods, with certain practical expedients available. We adopted the new standard prospectively as of January 1, 2019 and elected certain practical expedients permitted under the new standard’s transition guidance. This allows us to carry forward the historical lease classification and to not reassess the lease term for leases in existence as of the adoption date and to carry forward our historical accounting treatment for land easements on agreements existing on the adoption date. We also made policy elections for certain classes of underlying assets to not separate lease and non-lease components in a contract as permitted under the new standard. We currently lease real estate and equipment from third parties under operating leases and we lease certain satellites from third parties under capital leases. We also lease satellites, real estate and equipment to some of our customers. Upon adoption of the new standard, we recognized right-of-use assets and liabilities related to substantially all operating leases where we are the lessee. While our work is not finalized, we expect that the aggregate increase in our operating lease assets and liabilities will be approximately 1% of total assets as of January 1, 2019. Our accounting for capital leases was not significantly impacted on the adoption date. Based on our transition method, practical expedients and policy elections, our leases existing as of the adoption date will continue to be reported in our Consolidated Statements of Operations and Comprehensive Income (Loss) in accordance with current accounting standards throughout their remaining terms unless the leases are modified. However, all leases entered into or modified after the adoption date will be accounted for in accordance with the new standard. The classification of those leases as operating, finance or sales type may be impacted by the new standard and affect our future operating results and the classification of our cash flows. Recently Issued Accounting Pronouncements Not Yet Adopted Credit Losses In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments , which introduces a new approach to estimate credit losses on certain types of financial instruments based on expected losses instead of incurred losses. It also modifies the impairment model for available-for-sale debt securities and provides a simplified accounting model for purchased financial assets with credit deterioration since their origination. ASU No. 2016-13 is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. We are currently assessing the impact of adopting this new accounting standard on our Consolidated Financial Statements and related disclosures. Revenue Recognition and Financial Instruments On January 1, 2018, we adopted ASU No. 2014-09, Revenue from Contracts with Customers and related amendments (collectively, the “New Revenue Standard”) . The New Revenue Standard established a comprehensive new model for revenue recognition, which is codified in Topic 606 (see Revenue Recognition above), and provided guidance for certain costs associated with customer contracts. We adopted the New Revenue Standard using the modified retrospective method for contracts that were not completed as of January 1, 2018. Accordingly, comparative information for prior periods has not been restated and continues to be reported under the accounting standards in effect for those periods. Upon adoption of the New Revenue Standard, we recognized the cumulative effect of its initial application as a net increase to Accumulated earnings in our Consolidated Balance Sheets of $16 million , net of related income taxes. The adoption of the New Revenue Standard also impacted the timing of recognition of certain fees charged to our customers in our consumer markets; however, the adoption has not had, and we do not expect it to have, a material impact on the overall timing or amount of revenue recognition. The primary impacts of the New Revenue Standard on our operating results relate to how we account for sales incentive costs. Historically, we charged sales incentives to expense as incurred, except for incentives related to the consumer business in our Hughes segment, which were initially deferred and subsequently amortized over the related service agreement term. Under the New Revenue Standard, we continue to defer incentives for our consumer business; however, we now amortize those incentives over the estimated customer life, which includes expected contract renewal periods. In addition, we now defer certain sales incentives related to other businesses in our Hughes segment and amortize those incentives over the related service agreement term. As a result of these changes, we have recognized additional contract acquisition costs on our Consolidated Balance Sheets and the costs generally are recognized as expenses over a longer period of time in our Consolidated Statements of Operations and Comprehensive Income (Loss). The adoption of the New Revenue Standard by an unconsolidated entity had a similar impact on our investment in the unconsolidated entity, which we account for using the equity method. Additionally, on January 1, 2018, we prospectively adopted the applicable requirements of the New Investment Standard. The New Investment Standard substantially revises standards for the recognition, measurement and presentation of financial instruments, including requiring all equity investments, except for investments in consolidated subsidiaries and investments accounted for using the equity method, to be measured at fair value with changes in the fair value recognized through earnings. The New Investment Standard permits an entity to elect to measure an equity security without a readily determinable fair value at its cost, adjusted for changes resulting from impairments and observable price changes in orderly transactions for identical or similar securities of the same issuer. It also amends certain disclosure requirements associated with equity investments and the fair value of financial instruments. Upon adoption of the New Investment Standard on January 1, 2018, we recorded a $0.4 million charge to Accumulated earnings to include net unrealized losses on our marketable equity securities then designated as available for sale, which previously were recorded in Accumulated other comprehensive loss in our Consolidated Balance Sheets. For our equity investments without a readily determinable fair value that were previously accounted for using the cost method, we have elected to measure such securities at cost, adjusted for impairments and observable price changes. We expect our future net income or loss to be more volatile as a result of these changes in accounting for our investments in equity securities that were previously accounted for as available-for-sale or using the cost method.
