Business Description And Basis Of Presentation Text Block	1. BASIS OF PRESENTATION AND SIGNIFICANT POLICIES The condensed consolidated interim unaudited financial statements included herein have been prepared by Entercom Communications Corp. and its subsidiaries (collectively, the “Company”) in accordance with: (i) generally accepted accounting principles (“U.S. GAAP”) for interim financial information; and (ii) the instructions of the Securities and Exchange Commission (the “SEC”) for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for annual financial statements. In the opinion of management, the financial statements reflect all adjustments considered necessary for a fair statement of the results of operations and financial position for the interim periods presented. All such adjustments are of a normal and recurring nature. The Company's results are subject to seasonal fluctuations and, therefore, the results shown on an interim basis are not necessarily indicative of results for a full year. This Form 10-Q should be read in conjunction with the financial statements and related notes included in the Company's audited financial statements as of and for the year ended December 31, 2013 and filed with the SEC on March 3, 2014, as part of the Company's Annual Report on Form 10-K. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. There have been no material changes from Note 2, Significant Accounting Policies, as described in the notes to the Company's financial statements contained in its Form 10-K for the year ended December 31, 2013 that was filed with the SEC on March 3, 2014. Recent Accounting Pronouncements Stock-Based Performance Awards In June 2014, accounting guidance was updated for stock-based awards when the terms of an award provide that a performance target that affects vesting could be achieved after the requisite service period. The current accounting standard for stock-based compensation as it applies to awards with performance conditions should be applied. This guidance is effective for the Company as of January 1, 2016. The Company is currently evaluating this guidance, but does not anticipate it will have a material impact on its financial statements. Revenue From Contracts With Customers In May 2014, the accounting guidance was updated for revenue recognition from contracts with customers. Along with the update, most industry-specific revenue guidance was eliminated. The new guidance is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The guidance will be applied using one of two retrospective methods. The guidance is effective for the Company as of January 1, 2017. The Company has not determined the potential effects of this guidance on its financial statements. Reporting Discontinued Operations In April 2014, the criteria for reporting discontinued operations, including enhanced disclosures, was modified under new accounting guidance. Under the new guidance, only disposals that have a major effect through a strategic shift on an organization's operations and financial results should be presented as discontinued operations. In addition, the new guidance requires expanded disclosures that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. The guidance is effective for the Company as of January 1, 2016. The Company expects that this new guidance will reduce the number of transactions that will qualify for reporting discontinued operations. Netting Of Unrecognized Tax Benefits Against Tax Assets In June 2013, the accounting guidance was modified to require the netting of unrecognized tax benefits against a deferred tax asset for a loss or other carryforward that would apply in the settlement of uncertain tax positions. This guidance was effective for the Company beginning January 1, 2014. The adoption of this guidance did not have any effect on the presentation of the Company's consolidated financial statements as the Company's current and prior presentation conforms to this new guidance. Obligations Resulting From Joint And Several Liability Arrangements In February 2013, the accounting guidance was amended for obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. The amendments provide guidance on the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements, including debt arrangements, other contractual obligations, and settled litigation and judicial rulings, for which the total amount of the obligation is fixed at the reporting date. The amendment was effective for the Company beginning January 1, 2014 and was applied retrospectively. The adoption of this guidance did not have a material effect on the Company's results of operations, cash flows or financial condition.
