Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management of Iconix Brand Group, Inc. (the “Company,” “we,” “us,” or “our”), all adjustments (consisting primarily of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended September 30, 2017 (“Current Quarter”) and the nine months ended September 30, 2017 (“Current Nine Months”) are not necessarily indicative of the results that may be expected for a full fiscal year. The interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. During the Current Nine Months, the Company’s Board of Directors approved a plan to sell the businesses underlying our Entertainment segment representing the intellectual property of both the Peanuts and Strawberry Shortcake brands. As a result, the Company has classified the results of its Entertainment segment as discontinued operations in its condensed consolidated statement of operations for all periods presented. Additionally, the related assets and liabilities associated with the discontinued operations are classified as held for sale in its condensed consolidated balance sheet as of December 31, 2016. On May 9, 2017, the Company signed definitive agreements to sell its Entertainment segment. The sale of the Entertainment segment was completed on June 30, 2017. See Note 2 for further details. On June 30, 2017, the Company deconsolidated its Iconix SE Asia, Ltd. joint venture due to the receipt of the final purchase price installment payment from its joint venture partner, in respect of such partner’s interest in the joint venture. As a result, as of June 30, 2017, the Company is accounting for its investment in Iconix SE Asia, Ltd. as an equity method investment. Refer to Note 4 for further details. In July 2017, the Company purchased the remaining 50% ownership interest in both Iconix Canada L.P. and Ico Brands L.P (together with Iconix Canada L.P., collectively, “Iconix Canada”) owned by its joint venture partner for $19.0 million plus 50% of the net asset value of Iconix Canada (estimated to be approximately $2.0 million), in cash. Refer to Note 4 for further details. In the Current Nine Months, the Company recognized a loss of $26.0 million due to the early termination of licenses and a litigation settlement related to license terminations which has been recorded within loss on termination of licenses in the Company’s condensed consolidated statement of operations. During the Current Nine Months, the Company adopted four new accounting pronouncements. Refer to Note 18 for further details. The Company’s principal Ocean Pacific (“OP”) direct-to-retail (“DTR”) license agreement at Walmart was not renewed upon expiration in June 2017. The Company’s Starter DTR license agreement at Walmart will not be renewed upon expiration in December 2017. In October 2017 the Company also announced that Starter is now available on Amazon exclusively to Amazon Prime members. Additionally, the Company has learned that its Danskin Now license agreement with Walmart will not be renewed upon its expiration in January 2019 and royalty revenue for the Danskin Now brand at Walmart is estimated to decline approximately $15.5 million in 2018. The Company’s Mossimo DTR license agreement at Target will not be renewed upon expiration in October 2018 and royalty revenue for the Mossimo brand at Target is estimated to decline approximately $10.0 million in 2018. The Company is actively seeking to place OP, Danskin and Mossimo with new or existing licensees. At this time, the Company is uncertain how the terms and conditions of any potential replacement licensing arrangements could affect its future revenues and cash flows. As of September 30, 2017, as a result of a combination of factors, including the DTR non-renewals discussed above, the Company’s revised forecasted future earnings and an overall decline in sales in the retail industry during 2017, the Company conducted an interim indefinite-lived intangible impairment test in accordance with FASB Accounting Standards Codification Topic 350 – Intangibles – Goodwill and Other (“ASC 350”). In addition, as a result of the recent decline in the Company’s stock price and related market capitalization, the Company determined that there existed a further indication of potential impairment across all of the Company’s intangible assets. Consequently, the Company accelerated the timing of annual impairment testing of goodwill and intangible assets that is customarily performed in connection with the preparation of its year-end financial statements, and completed such testing in connection with the preparation of its financial statements for the Current Quarter. In the Current Quarter, the Company recorded a total non-cash asset impairment charge of $521.7 million which is comprised of $135.9 million in the men’s segment, $227.6 million in the women’s segment, $69.5 million in the home segment, and $88.8 million in the international segment to reduce various trademarks in those segments to fair value. Additionally, the Company recorded a total non-cash goodwill impairment charge of $103.9 million which is comprised of $73.9 million in the women’s segment, $1.5 million in the men’s segment and $28.4 million in the home segment. Certain reclassifications, which were immaterial, have been made to conform prior year data to the current presentation. Assessment of Going Concern These condensed consolidated financial statements are prepared on a going concern basis that contemplates the realization of assets and discharge of liabilities in the normal course of business. Due to certain developments, including the decision by Target Corporation not to renew the existing Mossimo license agreement following its expiration in October 2018 and by Walmart, Inc. not to renew the existing DanskinNow license agreement following its expiration in January 2019, and the Company’s revised forecasted future earnings, the Company forecasted that it would unlikely be in compliance with certain of its financial debt covenants in 2018 and that it may otherwise face possible liquidity challenges in 2018 as further described below. As a result, the Company recently engaged in discussions with its lenders to provide relief under its financial debt covenants and on October 27, 2017 entered into an amendment (the “First Amendment”) of its senior secured term loan facility with Deutsche Bank (the “DB Credit Agreement”). As a result of those negotiations, Deutsche Bank provided the Company with amended financial debt covenants and the Company agreed, among other things, to reduce the size of the credit facility by approximately $75 million to $225 million. The proceeds of the original senior secured term loan facility were escrowed to be utilized to refinance the Company’s 1.50% Convertible Notes (the “1.50% Convertible Notes”) when they come due in March 2018. Prior to entering into the First Amendment, the Company had already used $59 million of the escrowed proceeds made available under the original senior secured term loan facility to repay a portion of the 1.50% Convertible Notes and accrued interest. In connection with the First Amendment, the remaining escrowed funds from the original senior secured term loan facility were returned to Deutsche Bank and the bank agreed to provide the Company with a delayed draw term loan. The delayed draw term loan consists of (1) a $25 million First Delayed Draw Term Loan which amount was funded in full in accordance with the terms of the DB Credit Agreement, as amended (the “First Delayed Draw Term Loan”) and (ii) a $140.7 million Second Delayed Draw Term Loan to be drawn on March 15, 2018 (the “Second Delayed Draw Term Loan” and together with the First Delayed Draw Term Loan, the “Delayed Draw Term Loan Facility”). Pursuant to the amendment, in order to receive the net proceeds of the Second Delayed Draw Term Loan on March 15, 2018, the Company will have to raise net cash proceeds of at least $100 million (and/or achieving a reduction in the outstanding principal amount of the 1.50% Convertible Notes) which would provide sufficient funds with the amounts drawn under the Second Delayed Draw Term Loan for the Company to retire the 1.50% Convertible Notes outstanding on their maturity date. If the Company cannot secure additional funds or otherwise satisfy the requirements for availability of the First Delayed Draw Term Loan, the Company will not have sufficient liquidity to repay its 1.50% Convertible Notes which will become due in March 2018, which default may result in a cross-default and acceleration of the Company’s other outstanding indebtedness, which could ultimately force the Company into bankruptcy or liquidation. These factors raise substantial doubt about the Company’s ability to continue as a going concern within one year after the financial statements contained in this Quarterly Report on Form 10-Q (this “Quarterly Report”) are issued. In order to continue its operations, the Company continues to actively evaluate various capital raising options to repay debt and add additional liquidity to the Company’s balance sheet, as well as considering strategic alternatives, which could include the sale of certain assets or of the entire company, to sufficiently extend its cash and liquidity. There can be no assurance, however, that any of these alternatives will be successfully completed on terms acceptable to the Company to extend its cash and liquidity. The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

In the Current Nine Months, the Company recognized a loss of $26.0 million due to the early termination of licenses and a litigation settlement related to license terminations which has been recorded within loss on termination of licenses in the Company’s condensed consolidated statement of operations.

During the Current Nine Months, the Company adopted four new accounting pronouncements. Refer to Note 18 for further details.

The Company’s principal Ocean Pacific (“OP”) direct-to-retail (“DTR”) license agreement at Walmart was not renewed upon expiration in June 2017. The Company’s Starter DTR license agreement at Walmart will not be renewed upon expiration in December 2017.

The Company’s Mossimo DTR license agreement at Target will not be renewed upon expiration in October 2018 and royalty revenue for the Mossimo brand at Target is estimated to decline approximately $10.0 million in 2018. The Company is actively seeking to place OP, Danskin and Mossimo with new or existing licensees. At this time, the Company is uncertain how the terms and conditions of any potential replacement licensing arrangements could affect its future revenues and cash flows.

As of September 30, 2017, as a result of a combination of factors, including the DTR non-renewals discussed above, the Company’s revised forecasted future earnings and an overall decline in sales in the retail industry during 2017, the Company conducted an interim indefinite-lived intangible impairment test in accordance with FASB Accounting Standards Codification Topic 350 – Intangibles – Goodwill and Other (“ASC 350”).

Certain reclassifications, which were immaterial, have been made to conform prior year data to the current presentation.

Assessment of Going Concern

These condensed consolidated financial statements are prepared on a going concern basis that contemplates the realization of assets and discharge of liabilities in the normal course of business. Due to certain developments, including the decision by Target Corporation not to renew the existing Mossimo license agreement following its expiration in October 2018 and by Walmart, Inc. not to renew the existing DanskinNow license agreement following its expiration in January 2019, and the Company’s revised forecasted future earnings, the Company forecasted that it would unlikely be in compliance with certain of its financial debt covenants in 2018 and that it may otherwise face possible liquidity challenges in 2018 as further described below.

As a result, the Company recently engaged in discussions with its lenders to provide relief under its financial debt covenants and on October 27, 2017 entered into an amendment (the “First Amendment”) of its senior secured term loan facility with Deutsche Bank (the “DB Credit Agreement”). As a result of those negotiations, Deutsche Bank provided the Company with amended financial debt covenants and the Company agreed, among other things, to reduce the size of the credit facility by approximately $75 million to $225 million.

The proceeds of the original senior secured term loan facility were escrowed to be utilized to refinance the Company’s 1.50% Convertible Notes (the “1.50% Convertible Notes”) when they come due in March 2018. Prior to entering into the First Amendment, the Company had already used $59 million of the escrowed proceeds made available under the original senior secured term loan facility to repay a portion of the 1.50% Convertible Notes and accrued interest. In connection with the First Amendment, the remaining escrowed funds from the original senior secured term loan facility were returned to Deutsche Bank and the bank agreed to provide the Company with a delayed draw term loan. The delayed draw term loan consists of (1) a $25 million First Delayed Draw Term Loan which amount was funded in full in accordance with the terms of the DB Credit Agreement, as amended (the “First Delayed Draw Term Loan”) and (ii) a $140.7 million Second Delayed Draw Term Loan to be drawn on March 15, 2018 (the “Second Delayed Draw Term Loan” and together with the First Delayed Draw Term Loan, the “Delayed Draw Term Loan Facility”).

Pursuant to the amendment, in order to receive the net proceeds of the Second Delayed Draw Term Loan on March 15, 2018, the Company will have to raise net cash proceeds of at least $100 million (and/or achieving a reduction in the outstanding principal amount of the 1.50% Convertible Notes) which would provide sufficient funds with the amounts drawn under the Second Delayed Draw Term Loan for the Company to retire the 1.50% Convertible Notes outstanding on their maturity date. If the Company cannot secure additional funds or otherwise satisfy the requirements for availability of the First Delayed Draw Term Loan, the Company will not have sufficient liquidity to repay its 1.50% Convertible Notes which will become due in March 2018, which default may result in a cross-default and acceleration of the Company’s other outstanding indebtedness, which could ultimately force the Company into bankruptcy or liquidation. These factors raise substantial doubt about the Company’s ability to continue as a going concern within one year after the financial statements contained in this Quarterly Report on Form 10-Q (this “Quarterly Report”) are issued.

In order to continue its operations, the Company continues to actively evaluate various capital raising options to repay debt and add additional liquidity to the Company’s balance sheet, as well as considering strategic alternatives, which could include the sale of certain assets or of the entire company, to sufficiently extend its cash and liquidity. There can be no assurance, however, that any of these alternatives will be successfully completed on terms acceptable to the Company to extend its cash and liquidity. The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.
