SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Business iHeartMedia, Inc. (the “Company”) was formed in May 2007 by private equity funds sponsored by Bain Capital Partners, LLC and Thomas H. Lee Partners, L.P. (together, the “Sponsors”) for the purpose of acquiring the business of iHeartCommunications, Inc., a Texas company (“iHeartCommunications”). The acquisition was completed on July 30, 2008 pursuant to the Agreement and Plan of Merger, dated November 16, 2006, as amended on April 18, 2007, May 17, 2007 and May 13, 2008 (the “Merger Agreement”). The Company’s reportable segments are iHeartMedia (“iHM”), Americas outdoor advertising (“Americas outdoor”), and International outdoor advertising (“International outdoor”). The iHM segment provides media and entertainment services via broadcast and digital delivery. The Americas outdoor and International outdoor segments provide outdoor advertising services in their respective geographic regions using various digital and traditional display types. Included in the “Other” category are the Company’s media representation business, Katz Media Group, which is ancillary to its other businesses. During the first quarter of 2018, the Company reevaluated its segment reporting and determined that its Latin America operations should be managed by its International outdoor leadership team. As such, beginning January 1, 2018, our Latin American operations will be included in our International outdoor segment. Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates, judgments, and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes including, but not limited to, legal, tax and insurance accruals. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from those estimates. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries. Also included in the consolidated financial statements are entities for which the Company has a controlling financial interest or is the primary beneficiary. Investments in companies in which the Company owns 20% to 50% of the voting common stock or otherwise exercises significant influence over operating and financial policies of the Company are accounted for using the equity method of accounting. All significant intercompany accounts have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the 2017 presentation. Included in Selling, general and administrative expenses and Interest expense is $9.6 million and $1.4 million , respectively, recorded in the fourth quarter of 2017 to correct for accounting errors included in the results for our China subsidiary reported in prior years. Such corrections are not considered to be material to current year or prior year financial results. The Company is the beneficiary of two trusts created to comply with Federal Communications Commission (“FCC”) ownership rules. The radio stations owned by the trusts are managed by independent trustees. The trustees are marketing these stations for sale, and the stations will have to be sold unless any stations may be owned by the Company under then-current FCC rules, in which case the trusts will be terminated with respect to such stations. The trust agreements stipulate that the Company must fund any operating shortfalls of the trust activities, and any excess cash flow generated by the trusts is distributed to the Company. The Company is also the beneficiary of proceeds from the sale of stations held in the trusts. The Company consolidates the trusts in accordance with ASC 810-10, which requires an enterprise involved with variable interest entities to perform an analysis to determine whether the enterprise’s variable interest or interests give it a controlling financial interest in the variable interest entity, as the trusts were determined to be a variable interest entity and the Company is the primary beneficiary under the trusts. On March 14, 2018 , the Company, iHeartCommunications and certain of the Company's direct and indirect domestic subsidiaries (collectively, the "Debtors") filed voluntary petitions for relief (the "Chapter 11 Cases") under Chapter 11 of the United States Bankruptcy Code (the "Bankruptcy Code"), in the United States Bankruptcy Court for the Southern District of Texas, Houston Division (the "Bankruptcy Court"). Clear Channel Outdoor Holdings, Inc. (“CCOH”) and its direct and indirect subsidiaries did not file voluntary petitions for reorganization under the Bankruptcy Code and are not Debtors in the Chapter 11 Cases. The Chapter 11 Cases are being administered under the caption In re: iHeartMedia, Inc. , Case No. 18-31274 (MI). The Debtors will continue to operate their businesses as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. On March 16, 2018, the Debtors entered into a Restructuring Support Agreement (the “RSA”) with certain creditors and equityholders (the “Consenting Stakeholders”). The RSA contemplates the restructuring and recapitalization of the Debtors (the “Restructuring Transactions”), which will be implemented through a plan of reorganization in the Chapter 11 Cases, if confirmed by the Bankruptcy Court. Pursuant to the RSA, the Consenting Stakeholders have agreed to, among other things, support the Restructuring Transactions and vote in favor of a plan of reorganization to effect the Restructuring Transactions. The RSA provides certain milestones for the Restructuring Transactions. Failure of the Debtors to satisfy these milestones without a waiver or consensual amendment would provide the Consenting Stakeholders a termination right under the RSA. These milestones include (i) the filing of a plan of reorganization, disclosure statement and motion for approval of the disclosure statement, in form and substance reasonably acceptable to the Debtors and the Consenting Stakeholders, by April 28, 2018, (ii) the entry of an order approving the disclosure statement by July 7, 2018, (iii) the entry of an order confirming the plan of reorganization within 75 days of the entry of an order approving the disclosure statement and (iv) the effective date of the plan of reorganization occurring by March 14, 2019. In general, as debtors-in-possession under the Bankruptcy Code, we are authorized to continue to operate as an ongoing business, but may not engage in transactions outside the ordinary course of business without the prior approval of the Bankruptcy Court. Pursuant to first day motions filed with the Bankruptcy Court, the Bankruptcy Court authorized us to conduct our business activities in the ordinary course, including, among other things and subject to the terms and conditions of such orders, authorizing us to: (i) pay employees’ wages and related obligations; (ii) continue to operate our cash management system in a form substantially similar to prepetition practice; (iii) use cash collateral on an interim basis; (iv) continue to honor certain obligations related to on-air talent, station affiliates and royalty obligations; (v) continue to maintain certain customer programs; (vi) pay taxes in the ordinary course; (vii) continue our surety bond program; and (viii) maintain our insurance program in the ordinary course. iHeartCommunications, which is a Debtor in the Chapter 11 Cases, provides the day-to-day cash management services for CCOH’s cash activities and balances in the U.S. pursuant to the Corporate Services Agreement between iHeartCommunications and CCOH, and is continuing to do so during the Chapter 11 Cases pursuant to a cash management order approved by the Bankruptcy Court. CCOH does not have any material committed external sources of capital other than iHeartCommunications. iHeartCommunications' filing of the Chapter 11 Cases constitutes an event of default that accelerated its obligations under its debt agreements. Due to the Chapter 11 Cases, however, the creditors’ ability to exercise remedies under iHeartCommunications' debt agreements were stayed as of March 14, 2018 , the date of the Chapter 11 petition filing, and continue to be stayed. Going Concern The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern and contemplate the realization of assets and the satisfaction of liabilities in the normal course of business. The Company’s ability to continue as a going concern is contingent upon the Company’s ability to successfully implement the Company’s plan of reorganization, among other factors. As a result of the Chapter 11 Cases, the realization of assets and the satisfaction of liabilities are subject to uncertainty. While operating as debtors-in-possession under Chapter 11, the Company may sell or otherwise dispose of or liquidate assets or settle liabilities, subject to the approval of the Bankruptcy Court or as otherwise permitted in the ordinary course of business, for amounts other than those reflected in the accompanying consolidated financial statements. Further, the plan of reorganization could materially change the amounts and classifications of assets and liabilities reported in the consolidated financial statements. The accompanying consolidated financial statements do not include any adjustments related to the recoverability and classification of assets or the amounts and classification of liabilities or any other adjustments that might be necessary should the Company be unable to continue as a going concern or as a consequence of the Chapter 11 Cases. As a result of our financial condition, the defaults under our debt agreements, and the risks and uncertainties surrounding the Chapter 11 Cases, substantial doubt exists that we will be able to continue as a going concern. Cash and Cash Equivalents Cash and cash equivalents include all highly liquid investments with an original maturity of three months or less. Accounts Receivable Accounts receivable are recorded at the invoiced amount, net of reserves for sales returns and allowances, and allowances for doubtful accounts. The Company evaluates the collectability of its accounts receivable based on a combination of factors. In circumstances where it is aware of a specific customer’s inability to meet its financial obligations, it records a specific reserve to reduce the amounts recorded to what it believes will be collected. For all other customers, it recognizes reserves for bad debt based on historical experience of bad debts as a percent of revenue for each business unit, adjusted for relative improvements or deteriorations in the agings and changes in current economic conditions. The Company believes its concentration of credit risk is limited due to the large number and the geographic diversification of its customers. Business Combinations The Company accounts for its business combinations under the acquisition method of accounting. The total cost of an acquisition is allocated to the underlying identifiable net assets, based on their respective estimated fair values. The excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Determining the fair value of assets acquired and liabilities assumed requires management's judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, discount rates, asset lives and market multiples, among other items. Various acquisition agreements may include contingent purchase consideration based on performance requirements of the investee. The Company accounts for these payments in conformity with the provisions of ASC 805-20-30, which establish the requirements related to recognition of certain assets and liabilities arising from contingencies. Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line method at rates that, in the opinion of management, are adequate to allocate the cost of such assets over their estimated useful lives, which are as follows: Buildings and improvements – 10 to 39 years Structures – 3 to 20 years Towers, transmitters and studio equipment – 5 to 20 years Furniture and other equipment – 2 to 20 years Leasehold improvements – shorter of economic life or lease term assuming renewal periods, if appropriate For assets associated with a lease or contract, the assets are depreciated at the shorter of the economic life or the lease or contract term, assuming renewal periods, if appropriate. Expenditures for maintenance and repairs are charged to operations as incurred, whereas expenditures for renewal and betterments are capitalized. The Company tests for possible impairment of property, plant, and equipment whenever events and circumstances indicate that depreciable assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. When specific assets are determined to be unrecoverable, the cost basis of the asset is reduced to reflect the current fair market value. Assets and businesses are classified as held for sale if their carrying amount will be recovered or settled principally through a sale transaction rather than through continuing use. The asset or business must be available for immediate sale and the sale must be highly probable within one year. Leases Most of the Company’s outdoor advertising structures are located on leased land. Americas outdoor land leases are typically paid in advance for periods ranging from one to 12 months. International outdoor land leases are paid both in advance and in arrears, for periods ranging up to 12 months. Most international street furniture display faces are operated through contracts with municipalities for up to 15 years. The leased land and street furniture contracts often include a percent of revenue to be paid along with a base rent payment. Prepaid land leases are recorded as an asset and expensed ratably over the related rental term and rent payments in arrears are recorded as an accrued liability. The Company has entered into leases for tower sites for most of its broadcasting locations. Tower site leases are typically paid monthly in advance, and have 30 -year lease terms including annual rent escalations. Most tower site leases are operating leases, and operating lease expense is recognized straight-line based on the minimum lease payments for each lease. Intangible Assets The Company’s indefinite-lived intangible assets include FCC broadcast licenses in its iHM segment and billboard permits in its Americas outdoor advertising segment. The Company’s indefinite-lived intangible assets are not subject to amortization, but are tested for impairment at least annually. The Company tests for possible impairment of indefinite-lived intangible assets whenever events or changes in circumstances, such as a significant reduction in operating cash flow or a dramatic change in the manner for which the asset is intended to be used indicate that the carrying amount of the asset may not be recoverable. The Company performs its annual impairment test for its FCC licenses and permits using a direct valuation technique as prescribed in ASC 805-20-S99. The Company engages a third party valuation firm, to assist the Company in the development of these assumptions and the Company’s determination of the fair value of its FCC licenses and permits. Other intangible assets include definite-lived intangible assets and permanent easements. The Company’s definite-lived intangible assets include primarily transit and street furniture contracts, talent and representation contracts, customer and advertiser relationships, and site-leases, all of which are amortized over the respective lives of the agreements, or over the period of time the assets are expected to contribute directly or indirectly to the Company’s future cash flows. The Company periodically reviews the appropriateness of the amortization periods related to its definite-lived intangible assets. These assets are recorded at cost. Permanent easements are indefinite-lived intangible assets which include certain rights to use real property not owned by the Company. The Company tests for possible impairment of other intangible assets whenever events and circumstances indicate that they might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. When specific assets are determined to be unrecoverable, the cost basis of the asset is reduced to reflect the current fair market value. Goodwill At least annually, the Company performs its impairment test for each reporting unit’s goodwill. The Company uses a discounted cash flow model to determine if the carrying value of the reporting unit, including goodwill, is less than the fair value of the reporting unit. The Company identified its reporting units in accordance with ASC 350-20-55. The U.S. radio markets are aggregated into a single reporting unit and the Company’s U.S. outdoor advertising markets are aggregated into a single reporting unit for purposes of the goodwill impairment test. The Company also determined that within its Americas segment and its International outdoor segment each country constitutes a separate reporting unit. The Company recognized goodwill impairment of $1.6 million in 2017 related to one of our International outdoor markets. The Company recognized goodwill impairment of $7.3 million in 2016 related to one market in the Company's International outdoor segment. The Company had no impairment of goodwill in 2015 . Nonconsolidated Affiliates In general, investments in which the Company owns 20% to 50% of the common stock or otherwise exercises significant influence over the investee are accounted for under the equity method. The Company does not recognize gains or losses upon the issuance of securities by any of its equity method investees. The Company reviews the value of equity method investments and records impairment charges in the statement of operations as a component of “Equity in earnings (loss) of nonconsolidated affiliates” for any decline in value that is determined to be other-than-temporary. The Company recognized other-than-temporary impairment of $15.0 million on an equity investment for the year ended December 31, 2016, which was recorded in "Equity in loss of nonconsolidated affiliates." Other Investments Other investments are composed primarily of equity securities and notes receivable. Securities for which fair value is determinable are classified as available-for-sale or trading and are carried at fair value based on quoted market prices. Investments are carried at historical cost when quoted market prices are unavailable. The net unrealized gains or losses on the available-for-sale securities, net of tax, are reported in accumulated other comprehensive loss as a component of stockholders' deficit. The Company periodically assesses the value of available-for-sale and non-marketable securities and records impairment charges in the statement of comprehensive loss for any decline in value that is determined to be other-than-temporary. The average cost method is used to compute the realized gains and losses on sales of equity securities. Based on these assessments, the Company concluded that other-than-temporary impairments existed at December 31, 2017 , 2016 and 2015 and recorded noncash impairment charges of $4.2 million , $14.8 million and $5.0 million during 2017 , 2016 and 2015 , respectively. Such charge is recorded on the statement of comprehensive loss in “Loss on investments, net”. Financial Instruments Due to their short maturity, the carrying amounts of accounts and notes receivable, accounts payable, accrued liabilities, and short-term borrowings approximated their fair values at December 31, 2017 and 2016 . Income Taxes The Company accounts for income taxes using the liability method. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting bases and tax bases of assets and liabilities and are measured using the enacted tax rates expected to apply to taxable income in the periods in which the deferred tax asset or liability is expected to be realized or settled. Deferred tax assets are reduced by valuation allowances if the Company believes it is more likely than not that some portion or the entire asset will not be realized. The Company has not provided U.S. federal income taxes for temporary differences with respect to investments in foreign subsidiaries, which at December 31, 2017 currently result in tax basis amounts greater than the financial reporting basis. It is not apparent that these unrecognized deferred tax assets will reverse in the foreseeable future. If any excess cash held by our foreign subsidiaries were needed to fund operations in the U.S., we could presently repatriate available funds without a requirement to accrue or pay U.S. taxes as a result of significant deficits, as calculated for tax law purposes, in our foreign earnings and profits, which gives us flexibility to make future cash distributions as non-taxable returns of capital. Additionally, as a result of U.S. tax reform, future dividend distributions from our international subsidiaries are exempt from U.S. federal income tax beginning January 1, 2018. We regularly review our tax liabilities on amounts that may be distributed in future periods and provide for foreign withholding and other current and deferred taxes on any such amounts. Revenue Recognition iHM revenue is recognized as advertisements or programs are broadcast and is generally billed monthly. Outdoor advertising contracts typically cover periods of a few weeks up to one year and are generally billed monthly. Revenue for outdoor advertising space rental is recognized ratably over the term of the contract. Advertising revenue is reported net of agency commissions. Agency commissions are calculated based on a stated percentage applied to gross billing revenue for the Company’s media and entertainment and outdoor operations. Payments received in advance of being earned are recorded as deferred income. Revenue arrangements may contain multiple products and services and revenues are allocated based on the relative fair value of each delivered item and recognized in accordance with the applicable revenue recognition criteria for the specific unit of accounting. Barter transactions represent the exchange of advertising spots or display space for merchandise, services or other assets. These transactions are recorded at the estimated fair market value of the advertising spots or display space or the fair value of the merchandise or services or other assets received, whichever is most readily determinable. Revenue is recognized on trade and barter transactions when the advertisements are broadcasted or displayed. Expenses are recorded ratably over a period that estimates when the merchandise, service or other assets received is utilized, or when the event occurs. Trade and barter revenues and expenses from continuing operations are included in consolidated revenue and selling, general and administrative expenses, respectively. Trade and barter revenues and expenses from continuing operations were as follows: (In millions) Years Ended December 31, 2017 2016 2015 Trade and barter revenues $ 243.3 $ 165.8 $ 133.5 Trade and barter expenses 205.1 115.1 112.1 Trade and barter revenues for our iHeartMedia segment were $226.7 million , $153.3 million and $118.3 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. Trade and barter expenses for our iHeartMedia segment were $191.1 million , $103.1 million and $103.4 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. Advertising Expense The Company records advertising expense as it is incurred. Advertising expenses were $201.5 million , $132.7 million and $129.1 million for the years ended December 31, 2017 , 2016 and 2015 , respectively, which include $146.1 million , $68.9 million and $70.8 million in barter advertising, respectively. Share-Based Compensation Under the fair value recognition provisions of ASC 718-10, share-based compensation cost is measured at the grant date based on the fair value of the award. For awards that vest based on service conditions, this cost is recognized as expense on a straight-line basis over the vesting period. For awards that will vest based on market or performance conditions, this cost will be recognized when it becomes probable that the performance conditions will be satisfied. Determining the fair value of share-based awards at the grant date requires assumptions and judgments about expected volatility and forfeiture rates, among other factors. Foreign Currency Results of operations for foreign subsidiaries and foreign equity investees are translated into U.S. dollars using average exchange rates during the year. The assets and liabilities of those subsidiaries and investees are translated into U.S. dollars using the exchange rates at the balance sheet date. The related translation adjustments are recorded in a separate component of stockholders' deficit, “Accumulated other comprehensive loss”. Foreign currency transaction gains and losses are included in Other income (expense), net in the Statement of Comprehensive Loss. New Accounting Pronouncements During the third quarter of 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date . This update provides a one-year deferral of the effective date for ASU No. 2014-09, Revenue from Contracts with Customers . ASU No. 2014-09 provides guidance for the recognition, measurement and disclosure of revenue resulting from contracts with customers and will supersede virtually all of the current revenue recognition guidance under U.S. GAAP. The standard is effective for the first interim period within annual reporting periods beginning after December 15, 2017. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. The Company is using the full retrospective method. The Company has completed its evaluation of the changes from adopting the new standard on its future financial reporting and disclosures, which included reviews of contractual terms for all of the Company’s significant revenue streams and the development of an implementation plan. The Company has executed on its implementation plan, including drafting a detailed policy and training segment personnel. Based on its evaluation, the Company does not expect material changes to its consolidated revenues, operating income or balance sheets as a result of the implementation of this standard. During the first quarter of 2016, the FASB issued Accounting Standards Update No. 2016-01 (ASU 2016-01), Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 amends various aspects of the recognition, measurement, presentation, and disclosure for financial instruments. With respect to our consolidated financial statements, the most significant impact relates to the accounting for equity investments. The guidance will impact the disclosure and presentation of financial assets and liabilities. ASU 2016-01 is effective for annual reporting periods, and interim periods within those years beginning after December 15, 2017. Early adoption by public entities is permitted only for certain provisions. The Company is currently in the process of evaluating the impact of the adoption of this standard on our consolidated financial statements. During the first quarter of 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . The new leasing standard presents significant changes to the balance sheets of lessees. Lessor accounting is updated to align with certain changes in the lessee model and the new revenue recognition standard which was issued in the third quarter of 2015. The standard is effective for annual periods, and for interim periods within those annual periods, beginning after December 15, 2018. The Company is currently evaluating the impact of the provisions of this new standard on its consolidated financial statements. The Company expects the primary impact to our consolidated financial statements will be the recognition, on a discounted basis, of our minimum commitments under non-cancelable operating leases on our consolidated balance sheets resulting in the recording of right of use assets and lease obligations. Our current minimum commitments under non-cancelable operating leases are disclosed in Note 5. During the first quarter of 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350) . This update eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Entities will record an impairment charge based on the excess of a reporting unit's carrying amount over its fair value. The standard is effective for annual and any interim impairment tests performed for periods beginning after December 15, 2019. The Company is currently evaluating the impact of the provisions of this new standard on its consolidated financial statements. During the second quarter of 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718) . This update mandates that entities will apply the modification accounting guidance if the value, vesting conditions or classification of a stock-based award changes. Entities will have to make all of the disclosures about modifications that are required today, in addition to disclosing that compensation expense hasn't changed. Additionally, the new guidance also clarifies that a modification to an award could be significant and therefore require disclosure, even if the modification accounting is not required. The guidance will be applied prospectively to awards modified on or after the adoption date and is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The Company does not expect that the adoption of this guidance will have material effect on the Company's consolidated financial statements.

Property, Plant and Equipment [Abstract]
PROPERTY, PLANT AND EQUIPMENT, INTANGIBLE ASSETS AND GOODWILL	PROPERTY, PLANT AND EQUIPMENT, INTANGIBLEASSETS AND GOODWILL Acquisitions and Dispositions In January 2017, Americas outdoor sold its Indianapolis, Indiana market to Fairway Media Group, LLC in exchange for certain assets in Atlanta, Georgia with a fair value of $39.4 million , plus $43.1 million in cash, net of closing costs. The assets acquired as part of the transaction consisted of $9.9 million in fixed assets and $29.5 million in intangible assets (including $2.3 million in goodwill). The Company recognized a net gain of $28.9 million related to the sale, which is included within Other operating income (expense), net. During the third quarter of 2017, Americas outdoor sold its ownership interest in a joint venture in Canada. As a result, the Company recognized a net loss on sale of $12.1 million , including a $6.3 million cumulative translation adjustment, which is included within Other operating income (expense), net. During the fourth quarter of 2017, iHM exchanged four radio stations in Chattanooga, TN and six radio stations in Richmond, VA for four radio stations in Boston, MA and three radio stations in Seattle, WA, owned by Entercom Communications Corp. The assets acquired as part of the transaction consisted of $8.1 million in fixed assets and $63.2 million in intangible assets (including $2.4 million in goodwill). The Company recognized a net gain of $15.4 million related to the sale, which is included within Other operating income, net. Property, Plant and Equipment The Company’s property, plant and equipment consisted of the following classes of assets as of December 31, 2017 and 2016 , respectively: (In thousands) December 31, December 31, 2017 2016 Land, buildings and improvements $ 562,702 $ 570,566 Structures 2,864,442 2,684,673 Towers, transmitters and studio equipment 356,664 350,760 Furniture and other equipment 707,163 622,848 Construction in progress 74,810 91,655 4,565,781 4,320,502 Less: accumulated depreciation 2,681,067 2,372,340 Property, plant and equipment, net $ 1,884,714 $ 1,948,162 The Company recognized an impairment of $2.6 million during the year ended December 31, 2017 in relation to advertising assets that were no longer usable in one country in the Company's International outdoor segment. Indefinite-lived Intangible Assets The Company’s indefinite-lived intangible assets consist of FCC broadcast licenses and billboard permits. FCC broadcast licenses are granted to radio stations for up to eight years under the Telecommunications Act of 1996 (the “Act”). The Act requires the FCC to renew a broadcast license if the FCC finds that the station has served the public interest, convenience and necessity, there have been no serious violations of either the Communications Act of 1934 or the FCC’s rules and regulations by the licensee, and there have been no other serious violations which taken together constitute a pattern of abuse. The licenses may be renewed indefinitely at little or no cost. The Company does not believe that the technology of wireless broadcasting will be replaced in the foreseeable future. The Company’s billboard permits are granted for the right to operate an advertising structure at the specified location as long as the structure is in compliance with the laws and regulations of each jurisdiction. The Company’s permits are located on owned land, leased land or land for which we have acquired permanent easements. In cases where the Company’s permits are located on leased land, the leases typically have initial terms of between 10 and 20 years and renew indefinitely, with rental payments generally escalating at an inflation-based index. If the Company loses its lease, the Company will typically obtain permission to relocate the permit or bank it with the municipality for future use. Due to significant differences in both business practices and regulations, billboards in the International outdoor segment are subject to long-term, finite contracts unlike the Company’s permits in the United States and Canada. Accordingly, there are no indefinite-lived intangible assets in the International outdoor segment. Annual Impairment Test to Indefinite-lived Intangible Assets The Company performs its annual impairment test on indefinite-lived intangible assets as of July 1 of each year. The impairment tests for indefinite-lived intangible assets consist of a comparison between the fair value of the indefinite-lived intangible asset at the market level with its carrying amount. If the carrying amount of the indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized equal to that excess. After an impairment loss is recognized, the adjusted carrying amount of the indefinite-lived asset is its new accounting basis. The fair value of the indefinite-lived asset is determined using the direct valuation method as prescribed in ASC 805-20-S99. Under the direct valuation method, the fair value of the indefinite-lived assets is calculated at the market level as prescribed by ASC 350-30-35. The Company engaged a third-party valuation firm, to assist it in the development of the assumptions and the Company’s determination of the fair value of its indefinite-lived intangible assets. The application of the direct valuation method attempts to isolate the income that is properly attributable to the indefinite-lived intangible asset alone (that is, apart from tangible and identified intangible assets and goodwill). It is based upon modeling a hypothetical “greenfield” build-up to a “normalized” enterprise that, by design, lacks inherent goodwill and whose only other assets have essentially been paid for (or added) as part of the build-up process. The Company forecasts revenue, expenses, and cash flows over a ten -year period for each of its markets in its application of the direct valuation method. The Company also calculates a “normalized” residual year which represents the perpetual cash flows of each market. The residual year cash flow was capitalized to arrive at the terminal value of the licenses in each market. Under the direct valuation method, it is assumed that rather than acquiring indefinite-lived intangible assets as part of a going concern business, the buyer hypothetically develops indefinite-lived intangible assets and builds a new operation with similar attributes from scratch. Thus, the buyer incurs start-up costs during the build-up phase which are normally associated with going concern value. Initial capital costs are deducted from the discounted cash flow model which results in value that is directly attributable to the indefinite-lived intangible assets. The key assumptions using the direct valuation method are market revenue growth rates, market share, profit margin, duration and profile of the build-up period, estimated start-up capital costs and losses incurred during the build-up period, the risk-adjusted discount rate and terminal values. This data is populated using industry normalized information representing an average FCC license or billboard permit within a market. During 2017, the Company recognized an impairment charge of $6.0 million related to FCC licenses in one market. During 2016, the Company recognized an impairment charge of $0.7 million related to FCC licenses in one market. During 2015, the Company recognized an impairment charge of $21.6 million related to billboard permits in one market. Other Intangible Assets Other intangible assets include definite-lived intangible assets and permanent easements. The Company’s definite-lived intangible assets primarily include transit and street furniture contracts, talent and representation contracts, customer and advertiser relationships, and site-leases and other contractual rights, all of which are amortized over the shorter of either the respective lives of the agreements or over the period of time the assets are expected to contribute directly or indirectly to the Company’s future cash flows. Permanent easements are indefinite-lived intangible assets which include certain rights to use real property not owned by the Company. The Company periodically reviews the appropriateness of the amortization periods related to its definite-lived intangible assets. These assets are recorded at cost. The following table presents the gross carrying amount and accumulated amortization for each major class of other intangible assets as of December 31, 2017 and 2016 , respectively: (In thousands) December 31, 2017 December 31, 2016 Gross Carrying Amount Accumulated Amortization Gross Carrying Amount Accumulated Amortization Transit, street furniture and other outdoor contractual rights $ 548,918 $ (440,284 ) $ 563,863 $ (426,752 ) Customer / advertiser relationships 1,226,314 (1,133,251 ) 1,222,519 (1,012,380 ) Talent contracts 161,962 (138,728 ) 319,384 (281,060 ) Representation contracts 77,507 (62,753 ) 253,511 (229,413 ) Permanent easements 162,920 — 159,782 — Other 372,292 (224,841 ) 390,171 (219,117 ) Total $ 2,549,913 $ (1,999,857 ) $ 2,909,230 $ (2,168,722 ) Total amortization expense related to definite-lived intangible assets for the years ended December 31, 2017 , 2016 and 2015 was $197.2 million , $222.6 million , and $237.5 million , respectively. As acquisitions and dispositions occur in the future, amortization expense may vary. The following table presents the Company’s estimate of amortization expense for each of the five succeeding fiscal years for definite-lived intangible assets: (In thousands) 2018 $ 131,681 2019 44,972 2020 38,307 2021 33,618 2022 28,742 Annual Impairment Test to Goodwill The Company performs its annual impairment test on goodwill as of July 1 of each year. Each of the U.S. radio markets and outdoor advertising markets are components of the Company. The U.S. radio markets are aggregated into a single reporting unit and the U.S. outdoor advertising markets are aggregated into a single reporting unit for purposes of the goodwill impairment test using the guidance in ASC 350-20-55. The Company also determined that each country within its Americas outdoor segment and International outdoor segment constitutes a separate reporting unit. The goodwill impairment test is a two-step process. The first step, used to screen for potential impairment, compares the fair value of the reporting unit with its carrying amount, including goodwill. If applicable, the second step, used to measure the amount of the impairment loss, compares the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. Each of the Company’s reporting units is valued using a discounted cash flow model which requires estimating future cash flows expected to be generated from the reporting unit and discounting such cash flows to their present value using a risk-adjusted discount rate. Terminal values were also estimated and discounted to their present value. Assessing the recoverability of goodwill requires the Company to make estimates and assumptions about sales, operating margins, growth rates and discount rates based on its budgets, business plans, economic projections, anticipated future cash flows and marketplace data. There are inherent uncertainties related to these factors and management’s judgment in applying these factors. The Company recognized goodwill impairment of $1.6 million during the year ended December 31, 2017 related to one market in the Company's International outdoor segment. The Company recognized goodwill impairment of $7.3 million during the year year ended December 31, 2016 related to one market in the Company's International outdoor segment. The following table presents the changes in the carrying amount of goodwill in each of the Company’s reportable segments: (In thousands) iHM Americas Outdoor Advertising International Outdoor Advertising Other Consolidated Balance as of December 31, 2015 $ 3,288,481 $ 534,683 $ 223,892 $ 81,831 $ 4,128,887 Impairment — — (7,274 ) — (7,274 ) Dispositions — (6,934 ) (30,718 ) — (37,652 ) Foreign currency — (1,998 ) (5,051 ) — (7,049 ) Assets held for sale — (10,337 ) — — (10,337 ) Balance as of December 31, 2016 $ 3,288,481 $ 515,414 $ 180,849 $ 81,831 $ 4,066,575 Impairment — — (1,591 ) — (1,591 ) Acquisitions 2,442 2,252 — — 4,694 Dispositions (35,715 ) — (1,817 ) — (37,532 ) Foreign currency — 777 18,070 — 18,847 Assets held for sale — 89 — — 89 Balance as of December 31, 2017 $ 3,255,208 $ 518,532 $ 195,511 $ 81,831 $ 4,051,082 The balance at December 31, 2015 is net of cumulative impairments of $3.5 billion , $2.6 billion , $326.6 million and $212.0 million in the Company’s iHM, Americas outdoor, International outdoor and Other segments, respectively.

During 2017, the Company recorded $34.7 million in its iHM segment for investments made in thirteen private companies in exchange for advertising services and cash. Two of these investments are being accounted for under the equity method of accounting, six of these investments are being accounted for under the cost method of accounting, and five of these investments are notes receivable that are convertible into equity. During 2016, the Company recorded $26.1 million in its iHM segment for investments made in four private companies in exchange for advertising services and cash. Two of these investments are being accounted for under the equity method of accounting and two of these investments are being accounted for under the cost method. The Company recognized barter revenue of $35.2 million in the year ended December 31, 2017 and $36.6 million in the year ended December 31, 2016, in connection with these investments as services were provided. The Company recognized a non-cash impairment of $14.5 million on one of these cost investments for the year ended December 31, 2016, which was recorded in “Loss on investments, net.” In addition, the Company recognized a non-cash impairment of $15.0 million on one of these equity investments for the year ended December 31, 2016, which was recorded in "Equity in loss of nonconsolidated affiliates." Marketable Equity Securities ASC 820-10-35 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The Company’s marketable equity securities are measured at fair value on each reporting date. The marketable equity securities are measured at fair value using quoted prices in active markets. Due to the fact that the inputs used to measure the marketable equity securities at fair value are observable, the Company has categorized the fair value measurements of the securities as Level 1. As of December 31, 2017 and 2016 , the Company held $1.5 million and $1.7 million , respectively, in marketable equity securities, which are included within Other Assets.

Asset Retirement Obligation Disclosure [Abstract]
ASSET RETIREMENT OBLIGATION	ASSET RETIREMENT OBLIGATION The Company’s asset retirement obligation is reported in “Other long-term liabilities” with the current portion recorded in “Accrued liabilities” and relates to its obligation to dismantle and remove outdoor advertising displays from leased land and to reclaim the site to its original condition upon the termination or non-renewal of a lease or contract. When the liability is recorded, the cost is capitalized as part of the related long-lived assets’ carrying value. Due to the high rate of lease renewals over a long period of time, the calculation assumes that all related assets will be removed at some period over the next 55 years. An estimate of third-party cost information is used with respect to the dismantling of the structures and the reclamation of the site. The interest rate used to calculate the present value of such costs over the retirement period is based on an estimated risk adjusted credit rate for the same period. The following table presents the activity related to the Company’s asset retirement obligation: (In thousands) Years Ended December 31, 2017 2016 Beginning balance $ 42,491 $ 48,056 Adjustment due to changes in estimates 2,317 (5,343 ) Accretion of liability 3,555 5,090 Liabilities settled (2,880 ) (4,310 ) Foreign Currency 2,501 (1,002 ) Ending balance 47,984 42,491 Less: current portion 891 424 Long-term portion of asset retirement obligation $ 47,093 $ 42,067

On November 30, 2017, $300.0 million was drawn on the term loan and $65.0 million on the revolving credit commitments for a total of $365.0 million . The facility has a three -year term, maturing in 2020 and accrues interest at a rate of LIBOR plus 4.75% .

The Company’s weighted average interest rate at December 31, 2017 and 2016 was 8.9% and 8.5% , respectively. The aggregate market value of the Company’s debt based on market prices for which quotes were available was approximately $15.4 billion and $16.7 billion at December 31, 2017 and 2016 , respectively.

The filing of the voluntary petitions triggered an event of default under the Company's debt agreements. As a result, $14.7 billion in aggregate principal amount outstanding on the Company's long-term debt has been classified as current as of December 31, 2017 .

Subsidiary Revolving Credit Facility Due 2018 During the third quarter of 2013, CCOH entered into a five -year senior secured revolving credit facility with an aggregate principal amount of $75.0 million . The revolving credit facility may be used for working capital needs, to issue letters of credit and for other general corporate purposes. At December 31, 2017 , there were no amounts outstanding under the revolving credit facility, and $71.2 million of letters of credit under the revolving credit facility, which reduce availability under the facility. 14.0% Senior Notes due 2021 As of December 31, 2017 , iHeartCommunications had outstanding approximately $1.8 billion of aggregate principal amount of 14.0% Senior Notes due 2021 (net of $449.4 million principal amount held by a subsidiary of iHeartCommunications ). The 14.0% Senior Notes due 2021 mature on February 1, 2021. Interest on the 14.0% Senior Notes due 2021 is payable semi-annually on February 1 and August 1 of each year. Interest on the 14.0% Senior Notes due 2021 will be paid at the rate of (i) 12.0% per annum in cash and (ii) 2.0% per annum through the issuance of payment-in-kind notes (the “PIK Notes”). Any PIK Notes issued in certificated form will be dated as of the applicable interest payment date and will bear interest from and after such date. All PIK Notes issued will mature on February 1, 2021 and have the same rights and benefits as the 14.0% Senior Notes due 2021. Beginning with the interest payment due August 1, 2018 and continuing on each interest payment date thereafter, redemptions of a portion of the principal amount then outstanding will become due for purposes of applicable high yield discount obligation (“AHYDO”) catch-up payments. The 14.0% Senior Notes due 2021 are fully and unconditionally guaranteed on a senior basis by the guarantors named in the indenture governing such notes. The guarantee is structurally subordinated to all existing and future indebtedness and other liabilities of any subsidiary of the applicable subsidiary guarantor that is not also a guarantor of the 14.0% Senior Notes due 2021. The guarantees are subordinated to the guarantees of iHeartCommunications' senior secured credit facilities and certain other permitted debt, but rank equal to all other senior indebtedness of the guarantors. iHeartCommunications may redeem the 14.0% Senior Notes due 2021, in whole or in part, within certain dates, at the redemption prices set forth in the indenture plus accrued and unpaid interest to the redemption date. The indenture governing the 14.0% Senior Notes due 2021 contains covenants that limit iHeartCommunications' ability and the ability of its restricted subsidiaries to, among other things: (i) incur additional indebtedness or issue certain preferred stock; (ii) pay dividends on, or make distributions in respect of, iHeartCommunications' capital stock or repurchase iHeartCommunications' capital stock; (iii) make certain investments or other restricted payments; (iv) sell certain assets; (v) create liens or use assets as security in other transactions; (vi) merge, consolidate or transfer or dispose of substantially all of iHeartCommunications' assets; (vii) engage in transactions with affiliates; and (viii) designate iHeartCommunications' subsidiaries as unrestricted subsidiaries.

The $57.1 million of aggregate principal amount remains outstanding and is eliminated for purposes of consolidation of the Company’s financial statements. These senior notes were the obligations of iHeartCommunications prior to the merger in 2008. The senior notes are senior, unsecured obligations that are effectively subordinated to iHeartCommunications' secured indebtedness to the extent of the value of iHeartCommunications' assets securing such indebtedness and are not guaranteed by any of iHeartCommunications' subsidiaries and, as a result, are structurally subordinated to all indebtedness and other liabilities of iHeartCommunications' subsidiaries. The senior notes rank equally in right of payment with all of iHeartCommunications' existing and future senior indebtedness and senior in right of payment to all existing and future subordinated indebtedness. 10.0% Senior Notes due 2018 As of December 31, 2017 , iHeartCommunications had outstanding $47.5 million aggregate principal amount of 10.0% Senior Notes due 2018. The 10.0% Senior Notes due 2018 mature on January 15, 2018 and bear interest at a rate of 10.0% per annum, payable semi-annually on January 15 and July 15 of each year. On December 20, 2016, iHeartCommunications commenced an offer to noteholders to exchange its 10.0% Senior Notes due 2018 for newly-issued 11.25% Priority Guarantee Notes which were issued as “additional notes” under the indenture governing iHeartCommunications' existing 11.25% Priority Guarantee Notes due 2021. On February 7, 2017, iHeartCommunications completed the exchange offer by issuing $476.4 million in aggregate principal amount of 11.25% Priority Guarantee Notes due 2021 in exchange for $476.4 million of aggregate principal amount outstanding of its 10.0% Senior Notes due 2018, of which $241.4 million were held by subsidiaries of iHeartCommunications . On July 10, 2017, iHeartCommunications exchanged $15.6 million in aggregate principal amount of 11.25% Priority Guarantee Notes due 2021 that were held by a subsidiary of iHeartCommunications for $15.6 million of aggregate principal amount outstanding of its 10.0% Senior Notes due 2018 that were held by an unaffiliated third-party.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Commitments and Contingencies The Company accounts for its rentals that include renewal options, annual rent escalation clauses, minimum franchise payments and maintenance related to displays under the guidance in ASC 840. The Company considers its non-cancelable contracts that enable it to display advertising on buses, bus shelters, trains, etc. to be leases in accordance with the guidance in ASC 840-10. These contracts may contain minimum annual franchise payments which generally escalate each year. The Company accounts for these minimum franchise payments on a straight-line basis. If the rental increases are not scheduled in the lease, such as an increase based on subsequent changes in the index or rate, those rents are considered contingent rentals and are recorded as expense when accruable. Other contracts may contain a variable rent component based on revenue. The Company accounts for these variable components as contingent rentals and records these payments as expense when accruable. No single contract or lease is material to the Company’s operations. The Company accounts for annual rent escalation clauses included in the lease term on a straight-line basis under the guidance in ASC 840-20-25. The Company considers renewal periods in determining its lease terms if at inception of the lease there is reasonable assurance the lease will be renewed. Expenditures for maintenance are charged to operations as incurred, whereas expenditures for renewal and betterments are capitalized. The Company leases office space, certain broadcasting facilities, equipment and the majority of the land occupied by its outdoor advertising structures under long-term operating leases. The Company accounts for these leases in accordance with the policies described above. The Company’s contracts with municipal bodies or private companies relating to street furniture, billboards, transit and malls generally require the Company to build bus stops, kiosks and other public amenities or advertising structures during the term of the contract. The Company owns these structures and is generally allowed to advertise on them for the remaining term of the contract. Once the Company has built the structure, the cost is capitalized and expensed over the shorter of the economic life of the asset or the remaining life of the contract. In addition, the Company has commitments relating to required purchases of property, plant and equipment under certain street furniture contracts. Certain of the Company’s contracts contain penalties for not fulfilling its commitments related to its obligations to build bus stops, kiosks and other public amenities or advertising structures. Historically, any such penalties have not materially impacted the Company’s financial position or results of operations. As of December 31, 2017 , the Company's future minimum rental commitments under non-cancelable operating lease agreements with terms in excess of one year, minimum payments under non-cancelable contracts in excess of one year, capital expenditure commitments and employment/talent contracts consist of the following: (In thousands) Capital Non-Cancelable Non-Cancelable Expenditure Employment/Talent Operating Leases Contracts Commitments Contracts 2018 $ 492,013 $ 492,177 $ 38,444 $ 81,753 2019 446,396 409,343 7,928 61,603 2020 413,598 312,459 2,771 60,012 2021 368,399 267,834 4,499 20,310 2022 319,177 170,455 4,591 — Thereafter 2,050,060 393,713 9,877 — Total $ 4,089,643 $ 2,045,981 $ 68,110 $ 223,678 Rent expense charged to operations for the years ended December 31, 2017 , 2016 and 2015 was $1.13 billion , $1.12 billion and $1.14 billion , respectively. In various areas in which the Company operates, outdoor advertising is the object of restrictive and, in some cases, prohibitive zoning and other regulatory provisions, either enacted or proposed. The impact to the Company of loss of displays due to governmental action has been somewhat mitigated by Federal and state laws mandating compensation for such loss and constitutional restraints. The Company and its subsidiaries are involved in certain legal proceedings arising in the ordinary course of business and, as required, have accrued an estimate of the probable costs for the resolution of those claims for which the occurrence of loss is probable and the amount can be reasonably estimated. These estimates have been developed in consultation with counsel and are based upon an analysis of potential results, assuming a combination of litigation and settlement strategies. It is possible, however, that future results of operations for any particular period could be materially affected by changes in the Company’s assumptions or the effectiveness of its strategies related to these proceedings. Additionally, due to the inherent uncertainty of litigation, there can be no assurance that the resolution of any particular claim or proceeding would not have a material adverse effect on the Company’s financial condition or results of operations. Although the Company is involved in a variety of legal proceedings in the ordinary course of business, a large portion of its litigation arises in the following contexts: commercial disputes; defamation matters; employment and benefits related claims; governmental fines; intellectual property claims; and tax disputes. Stockholder Litigation On May 9, 2016, a stockholder of Clear Channel Outdoor Holdings, Inc. ("CCOH") filed a derivative lawsuit in the Court of Chancery of the State of Delaware, captioned GAMCO Asset Management Inc. v. iHeartMedia Inc. et al., C.A. No. 12312-VCS. The complaint names as defendants the Company, iHeartCommunications, Inc. ("iHeartCommunications"), an indirect subsidiary of the Company , Bain Capital Partners, LLC and Thomas H. Lee Partners, L.P. (together, the "Sponsor Defendants"), the Company's private equity sponsors and majority owners, and the members of CCOH's board of directors. CCOH also is named as a nominal defendant. The complaint alleges that CCOH has been harmed by the intercompany agreements with iHeartCommunications , CCOH’s lack of autonomy over its own cash and the actions of the defendants in serving the interests of the Company, iHeartCommunications and the Sponsor Defendants to the detriment of CCOH and its minority stockholders. Specifically, the complaint alleges that the defendants have breached their fiduciary duties by causing CCOH to: (i) continue to loan cash to iHeartCommunications under the intercompany note at below-market rates; (ii) abandon its growth and acquisition strategies in favor of transactions that would provide cash to the Company and iHeartCommunications ; (iii) issue new debt in the CCIBV note offering (the "CCIBV Note Offering") to provide cash to the Company and iHeartCommunications through a dividend; and (iv) effect the sales of certain outdoor markets in the U.S. (the "Outdoor Asset Sales") allegedly to provide cash to the Company and iHeartCommunications through a dividend. The complaint also alleges that the Company, iHeartCommunications and the Sponsor Defendants aided and abetted the directors' breaches of their fiduciary duties. The complaint further alleges that the Company, iHeartCommunications and the Sponsor Defendants were unjustly enriched as a result of these transactions and that these transactions constituted a waste of corporate assets for which the defendants are liable to CCOH. The plaintiff is seeking, among other things, a ruling that the defendants breached their fiduciary duties to CCOH and that the Company, iHeartCommunications and the Sponsor Defendants aided and abetted the CCOH board of directors' breaches of fiduciary duty, rescission of payments made by CCOH to iHeartCommunications and its affiliates pursuant to dividends declared in connection with the CCIBV Note Offering and Outdoor Asset Sales, and an order requiring the Company, iHeartCommunications and the Sponsor Defendants to disgorge all profits they have received as a result of the alleged fiduciary misconduct. On July 20, 2016, the defendants filed a motion to dismiss plaintiff's verified stockholder derivative complaint for failure to state a claim upon which relief can be granted. On November 23, 2016, the Court granted defendants’ motion to dismiss all claims brought by the plaintiff. On December 19, 2016, the plaintiff filed a notice of appeal of the ruling. The oral hearing on the appeal was held on October 11, 2017. On October 12, 2017, the Supreme Court of Delaware affirmed the lower court's ruling, dismissing the case. On December 29, 2017, another stockholder of CCOH filed a derivative lawsuit in the Court of Chancery of the State of Delaware, captioned Norfolk County Retirement System, v. iHeartMedia, Inc., et al., C.A. No. 2017-0930-JRS. The complaint names as defendants the Company, iHeartCommunications , the Sponsor Defendants, and the members of CCOH's board of directors. CCOH is named as a nominal defendant. The complaint alleges that CCOH has been harmed by the CCOH Board’s November 2017 decision to extend the maturity date of the intercompany revolving note (the “Third Amendment”) at what the complaint describes as far-below-market interest rates. Specifically, the complaint alleges that (i) the Company and Sponsor defendants breached their fiduciary duties by exploiting their position of control to require CCOH to enter the Third Amendment on terms unfair to CCOH; (ii) the CCOH Board breached their duty of loyalty by approving the Third Amendment and elevating the interests of the Company, iHeartCommunications and the Sponsor Defendants over the interests of CCOH and its minority unaffiliated stockholders; and (iii) the terms of the Third Amendment could not have been agreed to in good faith and represent a waste of corporate assets by the CCOH Board. The complaint further alleges that the Company, iHeartCommunications and the Sponsor defendants were unjustly enriched as a result of the unfairly favorable terms of the Third Amendment. The plaintiff is seeking, among other things, a ruling that the defendants breached their fiduciary duties to CCOH, a modification of the Third Amendment to bear a commercially reasonable rate of interest, and an order requiring disgorgement of all profits, benefits and other compensation obtained by defendants as a result of the alleged breaches of fiduciary duties. On March 7, 2018, the defendants filed a motion to dismiss plaintiff's verified derivative complaint for failure to state a claim upon which relief can be granted. On March 16, 2018, iHM filed a Notice of Suggestion of Pendency of Bankruptcy and Automatic Stay of Proceedings. China Investigation Several employees of Clear Media Limited, an indirect, non-wholly-owned subsidiary of the Company whose ordinary shares are listed, but are currently suspended from trading on, the Hong Kong Stock Exchange, are subject to an ongoing police investigation in China for misappropriation of funds. Clear Media Limited has conducted additional procedures and processes, including a special investigation by forensic accountants and an external law firm appointed by Clear Media Limited’s board of directors and approved by the Company’s Audit Committee, into the misappropriation of funds. During the course of the special investigation, it was discovered that three bank accounts were opened in the name of Clear Media Limited entities, which were not authorized, and certain transactions were recorded therein. The opening of the unauthorized bank accounts has also been referred to the police in China for investigation. The misappropriation of funds resulted in discrepancies between actual cash balances and cash amounts included in the Company’s accounting records as of December 31, 2016 and 2015. Included in Selling, general and administrative expenses and Interest expense is $9.6 million and $1.4 million , respectively, recorded in the fourth quarter of 2017 to correct for the accounting errors resulting from the discrepancies. Such accounting errors are not considered to be material to the current year or prior year financial statements. The Company advised both the United States Securities and Exchange Commission and the United States Department of Justice of the investigation at Clear Media Limited, and the Company intends to cooperate with both agencies in connection with any investigation that may be conducted in this matter. The police investigation is on-going, and the Company is not aware of any litigation, claim or assessment pending against the Company related to the matters described above. Based on information known to date, the Company believes any contingent liabilities arising from potential misconduct that has been or may be identified by the investigations are not material to the Company's consolidated financial statements. In 2017, Clear Media Limited accounted for 4.1% of the Company’s net revenue and 3.8% of its consolidated total assets. The investigation could implicate the books and records, internal controls and anti-bribery provisions of the U.S. Foreign Corrupt Practices Act, which statute and regulations provide for potential monetary penalties as well as criminal and civil sanctions. It is possible that monetary penalties and other sanctions could be assessed on the Company in connection with this matter. The nature and amount of any monetary penalty or other sanctions cannot reasonably be estimated at this time.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES On December 22, 2017, the U.S. government enacted comprehensive income tax legislation, referred to as The Tax Cuts and Jobs Act (the Tax Act). The Act reduces the U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred, and creates new U.S. taxes on certain foreign earnings. To account for the reduction in the U.S. federal corporate income tax rate, we remeasured our deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, generally 21%, which resulted in recording of a provisional deferred tax benefit of $510.1 million during 2017. To determine the impact from the one-time transition tax on accumulated foreign earnings, we analyzed our cumulative foreign earnings and profits in accordance with the rules provided in the Tax Act. Based upon our preliminary analysis which is not yet complete, we have not recorded income tax expense in the current period for the one-time transition tax due to the net accumulated deficit in our foreign earnings and profits. The provisions in the Tax Act are broad and complex. We have not yet completed our accounting for the income tax effects of the Tax Act as of December 31, 2017, but have made reasonable estimates of those effects on our existing deferred income tax balances and the one-time transition tax. The final financial statement impact of the Tax Act may differ from the above estimates, possibly materially, due to, among other things, changes in interpretations of the Tax Act, any legislative action to address questions that arise because of the Tax Act, and changes in accounting standards for income taxes or related interpretations in response to the Tax Act, or any updates to estimates the company has utilized to calculate the provisional impacts. The Securities and Exchange Commission (SEC) has issued rules that allow for a measurement period of up to one year after the enactment date of the Tax Act to finalize the recording of the related income tax impacts. Significant components of the provision for income tax benefit (expense) are as follows: (In thousands) Years Ended December 31, 2017 2016 2015 Current - Federal $ (2,136 ) $ (190 ) $ (31 ) Current - foreign (30,159 ) (44,555 ) (46,188 ) Current - state 1,484 (2,908 ) (12,890 ) Total current expense (30,811 ) (47,653 ) (59,109 ) Deferred - Federal 491,239 38,715 (30,719 ) Deferred - foreign (2,533 ) 56,747 5,269 Deferred - state (489 ) 2,665 (2,398 ) Total deferred benefit (expense) 488,217 98,127 (27,848 ) Income tax benefit (expense) $ 457,406 $ 50,474 $ (86,957 ) Current tax expense of $30.8 million was recorded for 2017 as compared to a current tax expense of $47.7 million for 2016 . The current tax expense recorded in 2017 was primarily related to foreign income taxes on operating profits generated in certain foreign jurisdictions during the period. The decrease in current tax expense when compared to 2016 was primarily attributable to a decrease in foreign tax expense which resulted primarily from a decrease in foreign earnings in certain jurisdictions during 2017. Current tax expense of $47.7 million was recorded for 2016 as compared to a current tax expense of $59.1 million for 2015. The current tax expense recorded in 2016 was primarily related to foreign income taxes on operating profits generated in certain foreign jurisdictions during the period. The decrease in current tax expense when compared to 2015 was primarily attributable to a decrease in state tax expense which resulted from a reduction in unrecognized tax benefits during 2016 in connection with the settlements of tax examinations during the period. Deferred tax benefit of $488.2 million was recorded for 2017 compared with deferred tax benefit of $98.1 million for 2016 . The increase in deferred tax benefit during 2017 was primarily attributed to the $510.1 million provisional deferred tax benefit recorded in connection with the remeasurement of our U.S. deferred tax balances upon the enactment of the Tax Act described above. In addition, the change in foreign deferred tax benefit recorded primarily related to the $43.3 million deferred tax benefit recorded in 2016 for the release of valuation allowance against certain net operating loss carryforwards in France. Deferred tax benefit of $98.1 million was recorded for 2016 compared with deferred tax expense of $27.8 million for 2015. The federal and state deferred tax benefits recorded in 2016 were primarily attributable to the reversal of certain U.S. deferred tax liabilities attributable to indefinite-lived intangible assets that were disposed of in connections with the sale of nine non-strategic U.S. outdoor markets during the first quarter of 2016. In addition, the foreign deferred tax benefit recorded in 2016 was primarily related to the $43.3 million deferred tax benefit for the release of valuation allowance against certain net operating loss carryforwards in France. Significant components of the Company's deferred tax liabilities and assets as of December 31, 2017 and 2016 are as follows: (In thousands) 2017 2016 Deferred tax liabilities: Intangibles and fixed assets $ 1,281,995 $ 2,018,159 Long-term debt — 37,205 Investments 16,484 — Other 9,868 10,159 Total deferred tax liabilities 1,308,347 2,065,523 Deferred tax assets: Accrued expenses 105,823 155,037 Long-term debt 49,767 — Investments — 5,458 Net operating loss carryforwards 1,106,319 1,384,175 Bad debt reserves 11,731 10,137 Other 27,654 43,545 Total gross deferred tax assets 1,301,294 1,598,352 Less: Valuation allowance 952,337 989,924 Total deferred tax assets 348,957 608,428 Net deferred tax liabilities $ 959,390 $ 1,457,095 The deferred tax liability related to intangibles and fixed assets primarily relates to the difference in book and tax basis of acquired FCC licenses, billboard permits and tax deductible goodwill created from the Company’s various stock acquisitions. In accordance with ASC 350-10, Intangibles—Goodwill and Other , the Company does not amortize FCC licenses and billboard permits. As a result, this deferred tax liability will not reverse over time unless the Company recognizes future impairment charges related to its FCC licenses, permits and tax deductible goodwill or sells its FCC licenses or permits. As the Company continues to amortize its tax basis in its FCC licenses, permits and tax deductible goodwill, the deferred tax liability will increase over time. The Company’s net foreign deferred tax assets for the periods ending December 31, 2017 and 2016 were $54.1 million and $47.1 million , respectively. At December 31, 2017 , the Company had recorded net operating loss carryforwards (tax effected) for federal and state income tax purposes of approximately $961.4 million , expiring in various amounts through 2037. The Company expects to realize the benefits of a portion of its deferred tax assets attributable to federal and state net operating losses based upon expected future taxable income from deferred tax liabilities that reverse in the relevant federal and state jurisdictions and carryforward periods. As of December 31, 2017 , the Company had recorded a valuation allowance of $827.3 million against a portion of these deferred tax assets which it does not expect to realize. After considering the deferred tax remeasurement adjustments described above in connection with the Tax Act, the Company's U.S. federal and state deferred tax valuation allowance decreased by $26.6 million during the current period. In addition, the Company recorded a net reduction of $11.0 million in valuation allowance against its foreign deferred tax assets during the year ended December 31, 2017 . At December 31, 2017 , the Company had recorded $144.9 million (tax-effected) of deferred tax assets for foreign net operating loss carryforwards, which are offset in part by an associated valuation allowance of $94.2 million . Additional deferred tax valuation allowance of $30.8 million offsets other foreign deferred tax assets that are not expected to be realized. Realization of these foreign deferred tax assets is dependent upon the Company’s ability to generate future taxable income in appropriate tax jurisdictions and carryforward periods. Due to the Company’s evaluation of all available evidence, including significant negative evidence of cumulative losses in these jurisdictions, the Company continues to record valuation allowances on the foreign deferred tax assets that are not expected to be realized. The Company expects to realize its remaining gross deferred tax assets based upon its assessment of deferred tax liabilities that will reverse in the same carryforward period and jurisdiction and are of the same character as the net operating loss carryforwards and temporary differences that give rise to the deferred tax assets. Any deferred tax liabilities associated with acquired FCC licenses, billboard permits and tax-deductible goodwill intangible assets are not relied upon as a source of future taxable income, as these intangible assets have an indefinite life. At December 31, 2017 , net deferred tax liabilities include a deferred tax asset of $16.3 million relating to stock-based compensation expense under ASC 718-10, Compensation—Stock Compensation . Full realization of this deferred tax asset requires stock options to be exercised at a price equaling or exceeding the sum of the grant price plus the fair value of the option at the grant date and restricted stock to vest at a price equaling or exceeding the fair market value at the grant date. Accordingly, there can be no assurance that the stock price of the Company’s common stock will rise to levels sufficient to realize the entire deferred tax benefit currently reflected in its balance sheet.

The effective tax benefit rate for 2017 was impacted by the effects of U.S. corporate tax reform which resulted in a provisional tax benefit of $510.1 million recorded in connection with the reduction in the U.S. federal corporate tax rate. In partial offset to this tax benefit, the company recorded tax expense of $387.7 million in connection with the valuation allowance recorded against federal and state deferred tax assets generated in the current period due to the uncertainty of the ability to realize those assets in future periods. A tax benefit was recorded for the year ended December 31, 2016 of 17.4% . The effective tax rate for 2016 was impacted by the $43.3 million deferred tax benefit recorded in connection with the release of valuation allowance in France, which was offset by $54.7 million of tax expense attributable to the sale of our outdoor business in Australia. Additionally, the 2016 effective tax benefit rate was impacted by the $31.8 million valuation allowance recorded against a portion of current period federal and state deferred tax assets due to the uncertainty of the ability to realize those assets in future periods. A tax expense was recorded for the year ended December 31, 2015 of (13.4)% . The effective tax rate for 2016 was impacted by the $305.3 million valuation allowance recorded during the period as additional deferred tax expense. The valuation allowance was recorded against a portion of the federal and state net operating losses due to the uncertainty of the ability to utilize those losses in future periods. The Company provides for any related tax liability on undistributed earnings that the Company does not intend to be indefinitely reinvested outside the United States and that would become taxable upon remittance within our foreign structure. At December 31, 2017, all undistributed earnings of our international subsidiaries have been included in our provisional computation of the one-time transition tax associated with the enactment of the Tax Act. Based upon our preliminary analysis of the effects of the Tax Act which is not yet complete, the Company has not provided U.S. federal income taxes for temporary differences with respect to investments in our foreign subsidiaries, which at December 31, 2017 currently result in tax basis amounts greater than the financial reporting basis. If any excess cash held by our foreign subsidiaries were needed to fund operations in the U.S., we could presently repatriate available funds without a requirement to accrue or pay U.S. taxes as a result of significant deficits, as calculated for tax law purposes, in our foreign earnings and profits, which gives us flexibility to make future cash distributions as non-taxable returns of capital. Additionally, as a result of U.S. tax reform described above, future dividend distributions from our international subsidiaries are exempt from U.S. federal income tax beginning January 1, 2018. The Company continues to record interest and penalties related to unrecognized tax benefits in current income tax expense. The total amount of interest accrued at December 31, 2017 and 2016 was $48.6 million and $47.5 million , respectively. The total amount of unrecognized tax benefits including accrued interest and penalties at December 31, 2017 and 2016 was $135.3 million and $145.4 million , respectively, of which $112.4 million and $115.1 million is included in “Other long-term liabilities” on the Company’s consolidated balance sheets, respectively. In addition, $22.8 million and $30.3 million of unrecognized tax benefits are recorded net with the Company’s deferred tax assets for its net operating losses as opposed to being recorded in “Other long-term liabilities” at December 31, 2017 and 2016 , respectively. The total amount of unrecognized tax benefits at December 31, 2017 and 2016 that, if recognized, would impact the effective income tax rate is $74.0 million and $53.8 million , respectively.

During 2017, the Company settled all outstanding U.S. federal income tax matters for tax years 2011 and 2012, which resulted in a reduction of unrecognized tax benefits of $4.7 million . In addition, during 2017 the statute of limitations for certain tax years expired in the U.S., certain states, the United Kingdom and other jurisdictions resulting in the reduction to unrecognized tax benefits of $15.3 million , excluding interest. During 2016, the company settled several tax examinations that resulted in the reduction of unrecognized tax benefits of $11.2 million , excluding interest, during the period. In addition, during 2016, the statute of limitations for certain tax years expired in the United Kingdom and other jurisdictions resulting in the reduction to unrecognized tax benefits of $6.2 million , excluding interest. All federal income tax matters through 2013 are closed. Substantially all material state, local, and foreign income tax matters have been concluded for years through 2008.

STOCKHOLDERS' DEFICIT	STOCKHOLDERS’ DEFICIT The Company reports its noncontrolling interests in consolidated subsidiaries as a component of equity separate from the Company’s equity. The following table shows the changes in stockholders' deficit attributable to the Company and the noncontrolling interests of subsidiaries in which the Company has a majority, but not total, ownership interest: (In thousands) The Company Noncontrolling Interests Consolidated Balances as of January 1, 2017 $ (11,021,253 ) $ 135,778 $ (10,885,475 ) Net income (loss) (393,891 ) (66,127 ) (460,018 ) Dividends and other payments to noncontrolling interests — (46,151 ) (46,151 ) Purchase of additional noncontrolling interests (524 ) (703 ) (1,227 ) Disposal of noncontrolling interests — (2,439 ) (2,439 ) Share-based compensation 2,488 9,590 12,078 Foreign currency translation adjustments 32,809 12,852 45,661 Unrealized holding loss on marketable securities (370 ) (44 ) (414 ) Other adjustments to comprehensive loss 6,013 707 6,720 Reclassifications adjustments 4,864 577 5,441 Other, net (355 ) (1,276 ) (1,631 ) Balances as of December 31, 2017 $ (11,370,219 ) $ 42,764 $ (11,327,455 ) (In thousands) The Company Noncontrolling Interests Consolidated Balances as of January 1, 2016 $ (10,784,841 ) $ 178,160 $ (10,606,681 ) Net income (loss) (296,362 ) 56,312 (240,050 ) Dividends and other payments to noncontrolling interests — (70,412 ) (70,412 ) Purchase of additional noncontrolling interests (1,224 ) 1,224 — Disposal of noncontrolling interests — (36,846 ) (36,846 ) Share-based compensation 2,842 10,291 13,133 Foreign currency translation adjustments 27,343 (5,360 ) 21,983 Unrealized holding gain on marketable securities (518 ) (58 ) (576 ) Other adjustments to comprehensive loss (10,622 ) (1,192 ) (11,814 ) Reclassifications adjustments 42,328 4,402 46,730 Other, net (199 ) (743 ) (942 ) Balances as of December 31, 2016 $ (11,021,253 ) $ 135,778 $ (10,885,475 ) Stock Registration On June 24, 2015, we registered 4,000,000 shares of the Company’s Class A common stock, par value $0.001 per share, for offer or sale under our 2015 Executive Long-Term Incentive Plan. On July 27, 2015, the board of directors approved the issuance of 1,253,831 restricted shares to certain key individuals pursuant to our 2015 Executive Long-term Incentive Plan. Dividends The Company has not paid cash dividends since its formation and its ability to pay dividends is subject to restrictions should it seek to do so in the future. iHeartCommunications' debt financing arrangements include restrictions on its ability to pay dividends thereby limiting the Company’s ability to pay dividends. On December 20, 2015, the board of directors of CCOH declared a special cash dividend, which was paid on January 7, 2016 to its stockholders of record at the closing of business on January 4, 2016 , in an aggregate amount equal to $217.8 million . Through our subsidiaries we received $196.3 million of this dividend. The remaining dividend was paid to CCOH’s public stockholders and was reflected as a use of cash for financing activities in the first quarter of 2016. In the first quarter of 2016, CCOH sold nine non-strategic Americas outdoor markets for an aggregate purchase price of approximately $592.3 million in cash and certain advertising assets in Florida (the “Transactions”). On January 21, 2016, the board of directors of CCOH notified iHeartCommunications of its intent to make a demand for the repayment of $300.0 million outstanding on the Note (the “Demand”) and declared special cash dividends in an aggregate amount of $540.0 million . CCOH made the Demand and the special cash dividend was paid on February 4, 2016 . A portion of the proceeds of the Transactions, together with the proceeds from the concurrent $300.0 million repayment of the Note, were used to fund the dividends. We received $486.5 million of the dividend proceeds ( $186.5 million net of iHeartCommunications’ repayment of the Note) through three of our wholly-owned subsidiaries, and approximately $53.5 million was paid to the public stockholders of CCOH. During the fourth quarter of 2016, CCOH sold its outdoor business in Australia for cash proceeds of $195.7 million , net of cash retained by the purchaser and closing costs. As discussed above under "Recent Liquidity-Generating Transactions," on February 9, 2017, CCOH declared a special dividend of $282.5 million using a portion of the cash proceeds from the sales of certain nonstrategic U.S. outdoor markets and of our Australia outdoor business. On February 23, 2017, we received 89.9% of the dividend, or approximately $254.0 million , with the remaining 10.1% , or approximately $28.5 million , paid to public stockholders of CCOH. On September 14, 2017, (i) CCOH provided notice of its intent to make a demand (the “First Demand”) for repayment on October 5, 2017 of $25.0 million outstanding under the Intercompany Note, and (ii) the board of directors of CCOH declared a special cash dividend, which was paid on October 5, 2017 to CCOH’s Class A and Class B stockholders of record at the closing of business on October 2, 2017, in an aggregate amount equal to $25.0 million , funded with the proceeds of the First Demand. The Company received approximately 89.5% , or approximately $22.4 million , of the proceeds of the dividend through its wholly-owned subsidiaries. The remaining approximately 10.5% of the proceeds of the dividend, or approximately $2.6 million , was paid to the public stockholders of CCOH. On October 11, 2017, (i) CCOH provided notice of its intent to make a demand (the “Second Demand”) for repayment on October 31, 2017 of $25.0 million outstanding under the Intercompany Note, and (ii) the board of directors of CCOH declared a special cash dividend, which was paid on October 31, 2017 to CCOH’s Class A and Class B stockholders of record at the closing of business on October 26, 2017, in an aggregate amount equal to $25.0 million , funded with the proceeds of the Second Demand. The Company received approximately 89.5% , or approximately $22.4 million , of the proceeds of the dividend through its wholly-owned subsidiaries. The remaining approximately 10.5% of the proceeds of the dividend, or approximately $2.6 million , was paid to the public stockholders of CCOH. On January 5, 2018, (i) CCOH provided notice of its intent to make a demand (the "Demand") for repayment on January 24, 2018 of $30.0 million outstanding under the Intercompany Note, and (ii) the board of directors of CCOH declared a special cash dividend, which was paid on January 24, 2018 to CCOH’s Class A and Class B stockholders of record at the closing of business on January 19, 2018, in an aggregate amount equal to $30.0 million , funded with the proceeds of the Demand. The Company received approximately 89.5% , or approximately $26.8 million , of the proceeds of the dividend through its wholly-owned subsidiaries. The remaining approximately 10.5% of the proceeds of the dividend, or approximately $3.2 million , was paid to the public stockholders of CCOH. Share-Based Compensation Stock Options Prior to the merger, iHeartCommunications granted options to purchase its common stock to its employees and directors and its affiliates under its various equity incentive plans typically at no less than the fair value of the underlying stock on the date of grant. These options were granted for a term not exceeding ten years and were forfeited, except in certain circumstances, in the event the employee or director terminated his or her employment or relationship with iHeartCommunications or one of its affiliates. Prior to acceleration, if any, in connection with the merger, these options vested over a period of up to five years. All equity incentive plans contained anti-dilutive provisions that permitted an adjustment of the number of shares of iHeartCommunications' common stock represented by each option for any change in capitalization. The Company has granted options to purchase its shares of Class A common stock to certain key executives under its equity incentive plan at no less than the fair value of the underlying stock on the date of grant. These options are granted for a term not to exceed ten years and are forfeited, except in certain circumstances, in the event the executive terminates his or her employment or relationship with the Company or one of its affiliates. Approximately three-fourths of the options outstanding at December 31, 2016 vest based solely on continued service over a period of up to five years with the remainder becoming eligible to vest over a period of up to five years if certain predetermined performance targets are met. The equity incentive plan contains antidilutive provisions that permit an adjustment for any change in capitalization. The Company accounts for its share-based payments using the fair value recognition provisions of ASC 718-10. The fair value of the portion of options that vest based on continued service is estimated on the grant date using a Black-Scholes option-pricing model and the fair value of the remaining options which contain vesting provisions subject to service, market and performance conditions is estimated on the grant date using a Monte Carlo model. Expected volatilities were based on historical volatility of peer companies’ stock, including the Company , over the expected life of the options. The expected life of the options granted represents the period of time that the options granted are expected to be outstanding. The Company used historical data to estimate option exercises and employee terminations within the valuation model. The Company includes estimated forfeitures in its compensation cost and updates the estimated forfeiture rate through the final vesting date of awards. The risk free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods equal to the expected life of the option. No options were granted during the years ended December 31, 2017 , 2016 and 2015 . The following table presents a summary of the Company's stock options outstanding at and stock option activity during the year ended December 31, 2017 ("Price" reflects the weighted average exercise price per share): (In thousands, except per share data) Options Price Weighted Average Remaining Contractual Term Outstanding, January 1, 2017 2,092 $ 35.09 2.6 years Granted — Exercised — Forfeited — Expired — Outstanding, December 31, 2017 (1) 2,092 35.09 1.6 years Exercisable 1,549 35.14 2.0 years Expected to Vest 543 34.94 0.7 years (1) Non-cash compensation expense has not been recorded with respect to 0.5 million shares as the vesting of these options is subject to performance conditions that have not yet been determined probable to meet.

Restricted Stock Awards The Company has granted restricted stock awards to certain of its employees and affiliates under its equity incentive plan. The restricted stock awards are restricted in transferability for a term of up to five years. Restricted stock awards are forfeited, except in certain circumstances, in the event the employee terminates his or her employment or relationship with the Company prior to the lapse of the restriction. Dividends or distributions paid in respect of unvested restricted stock awards will be held by the Company and paid to the recipients of the restricted stock awards upon vesting of the shares. The following table presents a summary of the Company's restricted stock outstanding and restricted stock activity as of and during the year ended December 31, 2017 (“Price” reflects the weighted average share price at the date of grant): (In thousands, except per share data) Awards Price Outstanding, January 1, 2017 5,772 $ 4.43 Granted 1,438 1.75 Vested (restriction lapsed) (677 ) 4.57 Forfeited (314 ) 4.09 Outstanding, December 31, 2017 6,219 3.81 CCOH Share-Based Awards CCOH Stock Options The Company’s subsidiary, CCOH, has granted options to purchase shares of its Class A common stock to employees and directors of CCOH and its affiliates under its equity incentive plan at no less than the fair market value of the underlying stock on the date of grant. These options are granted for a term not exceeding ten years and are forfeited, except in certain circumstances, in the event the employee or director terminates his or her employment or relationship with CCOH or one of its affiliates. These options vest solely on continued service over a period of up to five years. The equity incentive stock plan contains anti-dilutive provisions that permit an adjustment for any change in capitalization. The fair value of each option awarded on CCOH common stock is estimated on the date of grant using a Black-Scholes option-pricing model. Expected volatilities are based on historical volatility of CCOH’s stock over the expected life of the options. The expected life of options granted represents the period of time that options granted are expected to be outstanding. CCOH uses historical data to estimate option exercises and employee terminations within the valuation model. CCOH includes estimated forfeitures in its compensation cost and updates the estimated forfeiture rate through the final vesting date of awards. The risk free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods equal to the expected life of the option. The following assumptions were used to calculate the fair value of CCOH’s options on the date of grant: Years Ended December 31, 2017 2016 2015 Expected volatility 42% 42% – 44% 37% – 56% Expected life in years 6.3 6.3 6.3 Risk-free interest rate 2.12% 1.12% – 1.41% 1.70% – 2.07% Dividend yield —% —% —% The following table presents a summary of CCOH’s stock options outstanding at and stock option activity during the year ended December 31, 2017 : (In thousands, except per share data) Options Price (3) Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Outstanding, January 1, 2017 5,033 $ 7.04 4.9 years $ 2,539 Granted (1) 4 4.25 Exercised (2) (71 ) 3.10 Forfeited (96 ) 6.85 Expired (760 ) 12.49 Outstanding, December 31, 2017 4,110 6.10 4.1 years $ 2,378 Exercisable 3,392 6.01 3.4 years $ 2,359 Expected to vest 718 6.52 7.5 years $ 19 (1) The weighted average grant date fair value of CCOH options granted during the years ended December 31, 2017 , 2016 and 2015 was $2.04 , $2.82 and $4.25 per share, respectively. (2) Cash received from option exercises during the years ended December 31, 2017 , 2016 and 2015 was $0.2 million , $0.6 million and $3.8 million , respectively.

CCOH Restricted Stock Awards CCOH has also granted both restricted stock and restricted stock unit awards to its employees and affiliates under its equity incentive plan. The restricted stock awards represent shares of Class A common stock that hold a legend which restricts their transferability for a term of up to five years. The restricted stock units represent the right to receive shares upon vesting, which is generally over a period of up to five years. Both restricted stock awards and restricted stock units are forfeited, except in certain circumstances, in the event the employee terminates his or her employment or relationship with CCOH prior to the lapse of the restriction. The following table presents a summary of CCOH’s restricted stock and restricted stock units outstanding at and activity during the year ended December 31, 2017 ("Price" reflects the weighted average share price at the date of grant): (In thousands, except per share data) Awards Price Outstanding, January 1, 2017 2,743 $ 7.63 Granted 2,539 4.30 Vested (restriction lapsed) (1,040 ) 7.16 Forfeited (342 ) 7.39 Outstanding, December 31, 2017 3,900 5.61 Share-Based Compensation Cost The share-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense on a straight-line basis over the vesting period. Share-based compensation payments are recorded in corporate expenses and were $12.1 million , $13.1 million and $11.1 million , during the years ended December 31, 2017 , 2016 and 2015 , respectively. The tax benefit related to the share-based compensation expense for the years ended December 31, 2017 , 2016 and 2015 was $4.2 million , $5.0 million and $4.2 million , respectively. As of December 31, 2017 , there was $17.5 million of unrecognized compensation cost related to unvested share-based compensation arrangements that will vest based on service conditions. This cost is expected to be recognized over a weighted average period of approximately three years. In addition, as of December 31, 2017 , there was $26.5 million of unrecognized compensation cost related to unvested share-based compensation arrangements that will vest based on market, performance and service conditions. This cost will be recognized when it becomes probable that the performance condition will be satisfied. Loss per Share The following table presents the computation of loss per share for the years ended December 31, 2017 , 2016 and 2015 : (In thousands, except per share data) Years Ended December 31, 2017 2016 2015 NUMERATOR: Net loss attributable to the Company – common shares $ (393,891 ) $ (296,362 ) $ (754,774 ) DENOMINATOR: Weighted average common shares outstanding – basic 84,967 84,569 84,278 Stock options and restricted stock (1) : — — — Weighted average common shares outstanding – diluted 84,967 84,569 84,278 Net loss attributable to the Company per common share: Basic $ (4.64 ) $ (3.50 ) $ (8.96 ) Diluted $ (4.64 ) $ (3.50 ) $ (8.96 ) (1) 8.3 million , 7.9 million and 7.2 million stock options and restricted shares were outstanding at December 31, 2017 , 2016 and 2015 , respectively, that were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive. In December 2016, the Board of Directors and the Company's stockholders holding a majority of the votes entitled to be cast by all outstanding common stock of the Company approved a Fourth Amended and Restated Certificate of Incorporation (the "New Charter"), and the New Charter became effective on January 26, 2017 following the mailing of an Information Statement on Schedule 14C to the Company's stockholders. The New Charter authorizes the issuance of 200,000,000 shares of a new class of non-voting Class D Common Stock, par value $0.001 per share (the "Class D Common Stock"). The shares of Class D Common Stock authorized by the New Charter may be issued without further approval from the Company's stockholders. The New Charter also authorizes the issuance of 150,000,000 shares of "blank check" preferred stock, par value $0.001 per share (the "Preferred Stock").

Compensation and Retirement Disclosure [Abstract]
EMPLOYEE STOCK AND SAVINGS PLANS	EMPLOYEE STOCK AND SAVINGS PLANS iHeartCommunications has various 401(k) savings and other plans for the purpose of providing retirement benefits for substantially all employees. Under these plans, an employee can make pre-tax contributions and iHeartCommunications will match a portion of such an employee’s contribution. Employees vest in these iHeartCommunications matching contributions based upon their years of service to iHeartCommunications . Contributions of $29.0 million , $30.9 million and $28.9 million to these plans for the years ended December 31, 2017 , 2016 and 2015 , respectively, were expensed. iHeartCommunications offers a non-qualified deferred compensation plan for a select group of management or highly compensated employees, under which such employees were able to make an annual election to defer up to 50% of their annual salary and up to 80% of their bonus before taxes. iHeartCommunications suspended all salary and bonus deferrals and company matching contributions to the deferred compensation plan on January 1, 2010. iHeartCommunications accounts for the plan in accordance with the provisions of ASC 710-10. Matching credits on amounts deferred may be made in iHeartCommunications' sole discretion and iHeartCommunications retains ownership of all assets until distributed. Participants in the plan have the opportunity to allocate their deferrals and any iHeartCommunications matching credits among different investment options, the performance of which is used to determine the amounts to be paid to participants under the plan. In accordance with the provisions of ASC 710-10, the assets and liabilities of the non-qualified deferred compensation plan are presented in “Other assets” and “Other long-term liabilities” in the accompanying consolidated balance sheets, respectively. The asset and liability under the deferred compensation plan at December 31, 2017 was approximately $12.1 million recorded in “Other assets” and $12.1 million recorded in “Other long-term liabilities”, respectively. The asset and liability under the deferred compensation plan at December 31, 2016 was approximately $10.7 million recorded in “Other assets” and $10.7 million recorded in “Other long-term liabilities”, respectively.

In addition, during 2015 , 2016 and 2017 the Company recorded a valuation allowance of $305.3 million , $61.5 million and $387.7 million , respectively, on a portion of its deferred tax assets attributable to federal and state net operating loss carryforwards due to the uncertainty of the ability to utilize those losses in future periods. (2) During 2015 , 2016 and 2017 , the Company realized the tax benefits associated with certain foreign deferred tax assets, primarily related to foreign loss carryforwards, on which a valuation allowance was previously recorded. The associated valuation allowance was reversed in the period in which, based on the weight of available evidence, it is more-likely-than-not that the deferred tax asset will be realized. During 2016, the Company released valuation allowances in France in the amount of $43.3 million . (3) During 2015 , 2016 and 2017 , the Company adjusted certain valuation allowances as a result of changes in tax rates in certain jurisdictions and as a result of the expiration of carryforward periods for net operating loss carryforwards. During 2017, the Company adjusted the carrying value of its U.S. federal deferred tax balance due to the U.S. federal tax reform bill that was enacted in 2017. The tax bill reduced the U.S. federal corporate tax rate to 21% and resulted in a reduction to the valuation allowance balance of $336.3 million during the period.

SUMMARY OF SIGNIFICANT ACCOUN21

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates, judgments, and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes including, but not limited to, legal, tax and insurance accruals. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from those estimates.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries. Also included in the consolidated financial statements are entities for which the Company has a controlling financial interest or is the primary beneficiary. Investments in companies in which the Company owns 20% to 50% of the voting common stock or otherwise exercises significant influence over operating and financial policies of the Company are accounted for using the equity method of accounting. All significant intercompany accounts have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the 2017 presentation. Included in Selling, general and administrative expenses and Interest expense is $9.6 million and $1.4 million , respectively, recorded in the fourth quarter of 2017 to correct for accounting errors included in the results for our China subsidiary reported in prior years. Such corrections are not considered to be material to current year or prior year financial results. The Company is the beneficiary of two trusts created to comply with Federal Communications Commission (“FCC”) ownership rules. The radio stations owned by the trusts are managed by independent trustees. The trustees are marketing these stations for sale, and the stations will have to be sold unless any stations may be owned by the Company under then-current FCC rules, in which case the trusts will be terminated with respect to such stations. The trust agreements stipulate that the Company must fund any operating shortfalls of the trust activities, and any excess cash flow generated by the trusts is distributed to the Company. The Company is also the beneficiary of proceeds from the sale of stations held in the trusts. The Company consolidates the trusts in accordance with ASC 810-10, which requires an enterprise involved with variable interest entities to perform an analysis to determine whether the enterprise’s variable interest or interests give it a controlling financial interest in the variable interest entity, as the trusts were determined to be a variable interest entity and the Company is the primary beneficiary under the trusts.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include all highly liquid investments with an original maturity of three months or less.
Accounts Receivable	Accounts Receivable Accounts receivable are recorded at the invoiced amount, net of reserves for sales returns and allowances, and allowances for doubtful accounts. The Company evaluates the collectability of its accounts receivable based on a combination of factors. In circumstances where it is aware of a specific customer’s inability to meet its financial obligations, it records a specific reserve to reduce the amounts recorded to what it believes will be collected. For all other customers, it recognizes reserves for bad debt based on historical experience of bad debts as a percent of revenue for each business unit, adjusted for relative improvements or deteriorations in the agings and changes in current economic conditions. The Company believes its concentration of credit risk is limited due to the large number and the geographic diversification of its customers.
Business Combinations	Business Combinations The Company accounts for its business combinations under the acquisition method of accounting. The total cost of an acquisition is allocated to the underlying identifiable net assets, based on their respective estimated fair values. The excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Determining the fair value of assets acquired and liabilities assumed requires management's judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, discount rates, asset lives and market multiples, among other items. Various acquisition agreements may include contingent purchase consideration based on performance requirements of the investee. The Company accounts for these payments in conformity with the provisions of ASC 805-20-30, which establish the requirements related to recognition of certain assets and liabilities arising from contingencies.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line method at rates that, in the opinion of management, are adequate to allocate the cost of such assets over their estimated useful lives, which are as follows: Buildings and improvements – 10 to 39 years Structures – 3 to 20 years Towers, transmitters and studio equipment – 5 to 20 years Furniture and other equipment – 2 to 20 years Leasehold improvements – shorter of economic life or lease term assuming renewal periods, if appropriate For assets associated with a lease or contract, the assets are depreciated at the shorter of the economic life or the lease or contract term, assuming renewal periods, if appropriate. Expenditures for maintenance and repairs are charged to operations as incurred, whereas expenditures for renewal and betterments are capitalized. The Company tests for possible impairment of property, plant, and equipment whenever events and circumstances indicate that depreciable assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. When specific assets are determined to be unrecoverable, the cost basis of the asset is reduced to reflect the current fair market value. Assets and businesses are classified as held for sale if their carrying amount will be recovered or settled principally through a sale transaction rather than through continuing use. The asset or business must be available for immediate sale and the sale must be highly probable within one year.
Leases	Leases Most of the Company’s outdoor advertising structures are located on leased land. Americas outdoor land leases are typically paid in advance for periods ranging from one to 12 months. International outdoor land leases are paid both in advance and in arrears, for periods ranging up to 12 months. Most international street furniture display faces are operated through contracts with municipalities for up to 15 years. The leased land and street furniture contracts often include a percent of revenue to be paid along with a base rent payment. Prepaid land leases are recorded as an asset and expensed ratably over the related rental term and rent payments in arrears are recorded as an accrued liability. The Company has entered into leases for tower sites for most of its broadcasting locations. Tower site leases are typically paid monthly in advance, and have 30 -year lease terms including annual rent escalations. Most tower site leases are operating leases, and operating lease expense is recognized straight-line based on the minimum lease payments for each lease.
Intangible Assets	Intangible Assets The Company’s indefinite-lived intangible assets include FCC broadcast licenses in its iHM segment and billboard permits in its Americas outdoor advertising segment. The Company’s indefinite-lived intangible assets are not subject to amortization, but are tested for impairment at least annually. The Company tests for possible impairment of indefinite-lived intangible assets whenever events or changes in circumstances, such as a significant reduction in operating cash flow or a dramatic change in the manner for which the asset is intended to be used indicate that the carrying amount of the asset may not be recoverable. The Company performs its annual impairment test for its FCC licenses and permits using a direct valuation technique as prescribed in ASC 805-20-S99. The Company engages a third party valuation firm, to assist the Company in the development of these assumptions and the Company’s determination of the fair value of its FCC licenses and permits. Other intangible assets include definite-lived intangible assets and permanent easements. The Company’s definite-lived intangible assets include primarily transit and street furniture contracts, talent and representation contracts, customer and advertiser relationships, and site-leases, all of which are amortized over the respective lives of the agreements, or over the period of time the assets are expected to contribute directly or indirectly to the Company’s future cash flows. The Company periodically reviews the appropriateness of the amortization periods related to its definite-lived intangible assets. These assets are recorded at cost. Permanent easements are indefinite-lived intangible assets which include certain rights to use real property not owned by the Company. The Company tests for possible impairment of other intangible assets whenever events and circumstances indicate that they might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. When specific assets are determined to be unrecoverable, the cost basis of the asset is reduced to reflect the current fair market value.
Goodwill	Goodwill At least annually, the Company performs its impairment test for each reporting unit’s goodwill. The Company uses a discounted cash flow model to determine if the carrying value of the reporting unit, including goodwill, is less than the fair value of the reporting unit. The Company identified its reporting units in accordance with ASC 350-20-55. The U.S. radio markets are aggregated into a single reporting unit and the Company’s U.S. outdoor advertising markets are aggregated into a single reporting unit for purposes of the goodwill impairment test.
Nonconsolidated Affiliates	Nonconsolidated Affiliates In general, investments in which the Company owns 20% to 50% of the common stock or otherwise exercises significant influence over the investee are accounted for under the equity method. The Company does not recognize gains or losses upon the issuance of securities by any of its equity method investees. The Company reviews the value of equity method investments and records impairment charges in the statement of operations as a component of “Equity in earnings (loss) of nonconsolidated affiliates” for any decline in value that is determined to be other-than-temporary.
Other Investments	Other Investments Other investments are composed primarily of equity securities and notes receivable. Securities for which fair value is determinable are classified as available-for-sale or trading and are carried at fair value based on quoted market prices. Investments are carried at historical cost when quoted market prices are unavailable. The net unrealized gains or losses on the available-for-sale securities, net of tax, are reported in accumulated other comprehensive loss as a component of stockholders' deficit. The Company periodically assesses the value of available-for-sale and non-marketable securities and records impairment charges in the statement of comprehensive loss for any decline in value that is determined to be other-than-temporary. The average cost method is used to compute the realized gains and losses on sales of equity securities.
Financial Instruments	Financial Instruments Due to their short maturity, the carrying amounts of accounts and notes receivable, accounts payable, accrued liabilities, and short-term borrowings approximated their fair values at December 31, 2017 and 2016 .
Income Taxes	Income Taxes The Company accounts for income taxes using the liability method. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting bases and tax bases of assets and liabilities and are measured using the enacted tax rates expected to apply to taxable income in the periods in which the deferred tax asset or liability is expected to be realized or settled. Deferred tax assets are reduced by valuation allowances if the Company believes it is more likely than not that some portion or the entire asset will not be realized. The Company has not provided U.S. federal income taxes for temporary differences with respect to investments in foreign subsidiaries, which at December 31, 2017 currently result in tax basis amounts greater than the financial reporting basis. It is not apparent that these unrecognized deferred tax assets will reverse in the foreseeable future. If any excess cash held by our foreign subsidiaries were needed to fund operations in the U.S., we could presently repatriate available funds without a requirement to accrue or pay U.S. taxes as a result of significant deficits, as calculated for tax law purposes, in our foreign earnings and profits, which gives us flexibility to make future cash distributions as non-taxable returns of capital. Additionally, as a result of U.S. tax reform, future dividend distributions from our international subsidiaries are exempt from U.S. federal income tax beginning January 1, 2018. We regularly review our tax liabilities on amounts that may be distributed in future periods and provide for foreign withholding and other current and deferred taxes on any such amounts.
Revenue Recognition	Revenue Recognition iHM revenue is recognized as advertisements or programs are broadcast and is generally billed monthly. Outdoor advertising contracts typically cover periods of a few weeks up to one year and are generally billed monthly. Revenue for outdoor advertising space rental is recognized ratably over the term of the contract. Advertising revenue is reported net of agency commissions. Agency commissions are calculated based on a stated percentage applied to gross billing revenue for the Company’s media and entertainment and outdoor operations. Payments received in advance of being earned are recorded as deferred income. Revenue arrangements may contain multiple products and services and revenues are allocated based on the relative fair value of each delivered item and recognized in accordance with the applicable revenue recognition criteria for the specific unit of accounting. Barter transactions represent the exchange of advertising spots or display space for merchandise, services or other assets. These transactions are recorded at the estimated fair market value of the advertising spots or display space or the fair value of the merchandise or services or other assets received, whichever is most readily determinable. Revenue is recognized on trade and barter transactions when the advertisements are broadcasted or displayed. Expenses are recorded ratably over a period that estimates when the merchandise, service or other assets received is utilized, or when the event occurs. Trade and barter revenues and expenses from continuing operations are included in consolidated revenue and selling, general and administrative expenses, respectively.
Advertising Expense	Advertising Expense The Company records advertising expense as it is incurred.
Share-Based Compensation	Share-Based Compensation Under the fair value recognition provisions of ASC 718-10, share-based compensation cost is measured at the grant date based on the fair value of the award. For awards that vest based on service conditions, this cost is recognized as expense on a straight-line basis over the vesting period. For awards that will vest based on market or performance conditions, this cost will be recognized when it becomes probable that the performance conditions will be satisfied. Determining the fair value of share-based awards at the grant date requires assumptions and judgments about expected volatility and forfeiture rates, among other factors.
Foreign Currency	Foreign Currency Results of operations for foreign subsidiaries and foreign equity investees are translated into U.S. dollars using average exchange rates during the year. The assets and liabilities of those subsidiaries and investees are translated into U.S. dollars using the exchange rates at the balance sheet date. The related translation adjustments are recorded in a separate component of stockholders' deficit, “Accumulated other comprehensive loss”. Foreign currency transaction gains and losses are included in Other income (expense), net in the Statement of Comprehensive Loss.
New Accounting Pronouncements	New Accounting Pronouncements During the third quarter of 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date . This update provides a one-year deferral of the effective date for ASU No. 2014-09, Revenue from Contracts with Customers . ASU No. 2014-09 provides guidance for the recognition, measurement and disclosure of revenue resulting from contracts with customers and will supersede virtually all of the current revenue recognition guidance under U.S. GAAP. The standard is effective for the first interim period within annual reporting periods beginning after December 15, 2017. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. The Company is using the full retrospective method. The Company has completed its evaluation of the changes from adopting the new standard on its future financial reporting and disclosures, which included reviews of contractual terms for all of the Company’s significant revenue streams and the development of an implementation plan. The Company has executed on its implementation plan, including drafting a detailed policy and training segment personnel. Based on its evaluation, the Company does not expect material changes to its consolidated revenues, operating income or balance sheets as a result of the implementation of this standard. During the first quarter of 2016, the FASB issued Accounting Standards Update No. 2016-01 (ASU 2016-01), Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 amends various aspects of the recognition, measurement, presentation, and disclosure for financial instruments. With respect to our consolidated financial statements, the most significant impact relates to the accounting for equity investments. The guidance will impact the disclosure and presentation of financial assets and liabilities. ASU 2016-01 is effective for annual reporting periods, and interim periods within those years beginning after December 15, 2017. Early adoption by public entities is permitted only for certain provisions. The Company is currently in the process of evaluating the impact of the adoption of this standard on our consolidated financial statements. During the first quarter of 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . The new leasing standard presents significant changes to the balance sheets of lessees. Lessor accounting is updated to align with certain changes in the lessee model and the new revenue recognition standard which was issued in the third quarter of 2015. The standard is effective for annual periods, and for interim periods within those annual periods, beginning after December 15, 2018. The Company is currently evaluating the impact of the provisions of this new standard on its consolidated financial statements. The Company expects the primary impact to our consolidated financial statements will be the recognition, on a discounted basis, of our minimum commitments under non-cancelable operating leases on our consolidated balance sheets resulting in the recording of right of use assets and lease obligations. Our current minimum commitments under non-cancelable operating leases are disclosed in Note 5. During the first quarter of 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350) . This update eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Entities will record an impairment charge based on the excess of a reporting unit's carrying amount over its fair value. The standard is effective for annual and any interim impairment tests performed for periods beginning after December 15, 2019. The Company is currently evaluating the impact of the provisions of this new standard on its consolidated financial statements. During the second quarter of 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718) . This update mandates that entities will apply the modification accounting guidance if the value, vesting conditions or classification of a stock-based award changes. Entities will have to make all of the disclosures about modifications that are required today, in addition to disclosing that compensation expense hasn't changed. Additionally, the new guidance also clarifies that a modification to an award could be significant and therefore require disclosure, even if the modification accounting is not required. The guidance will be applied prospectively to awards modified on or after the adoption date and is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The Company does not expect that the adoption of this guidance will have material effect on the Company's consolidated financial statements.
