Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Future Commitments The radio broadcast industry’s principal ratings service is Nielsen Audio (“Nielsen”), which publishes surveys for domestic radio markets. Certain of the Company’s subsidiaries have agreements with Nielsen under which they receive programming ratings information. The remaining aggregate obligation under the agreements with Nielsen is approximately $138.8 million, as of March 31, 2019, and is expected to be paid in accordance with the agreements through December 2021. The Company engages Katz Media Group, Inc. (“Katz”) as its national advertising sales agent. The national advertising agency contract with Katz contains termination provisions that, if exercised by the Company during the term of the contract, would obligate the Company to pay a termination fee to Katz, based upon a formula set forth in the contract. The Company is committed under various contractual agreements to pay for broadcast rights that include sports and news services and to pay for talent, executives, research, weather information and other services. The Company from time to time enters into radio network contractual obligations to guarantee a minimum amount of revenue share to contractual counterparties on certain programming in future years. As of March 31, 2019, the Company believes that it will meet all such material minimum obligations. Legal Proceedings In August 2015, the Company was named as a defendant in two separate putative class action lawsuits relating to its use and public performance of certain sound recordings fixed prior to February 15, 1972 (the "Pre-1972 Recordings"). The first suit, ABS Entertainment, Inc., et. al. v, Cumulus Media Inc., was filed in the United States District Court for the Central District of California and alleged, among other things, copyright infringement under California state law, common law conversion, misappropriation and unfair business practices. On December 11, 2015, this suit was dismissed without prejudice. The second suit, ABS Entertainment, Inc., v. Cumulus Media Inc., was filed in the United States District Court for the Southern District of New York and claimed, among other things, common law copyright infringement and unfair competition. The New York lawsuit was stayed pending an appeal before the Second Circuit involving unrelated third parties over whether the owner of a Pre-1972 Recording holds an exclusive right to publicly perform that recording under New York common law. On December 20, 2016, the New York Court of Appeals held that New York common law does not recognize a right of public performance for owners of pre-1972 Recordings. As a result of that case (to which Cumulus Media Inc. was not a party) the New York case against Cumulus Media Inc., was voluntarily dismissed by the plaintiffs on April 3, 2017. On October 11, 2018, President Trump signed the Orrin G. Hatch-Bob Goodlatte Music Modernization Act into law, which, among other things, provides new federal rights going forward for owners of pre-1972 Recordings. The question of whether public performance rights existed for Pre-1972 recordings under state law prior to the enactment of the new Music Modernization Act is still being litigated in the Ninth Circuit as a result of a case filed in California. Cumulus is not a party to that case, and the Company is not yet able to determine what effect that proceeding will have, if any, on its financial position, results of operations or cash flows. The Company currently is, and expects that from time to time in the future it will be, party to, or a defendant in, various other claims or lawsuits that are generally incidental to its business. The Company expects that it will vigorously contest any such claims or lawsuits and believes that the ultimate resolution of any such known claim or lawsuit will not have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows.
