Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(2) Summary of Significant Accounting Policies Principles of Consolidation The financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America and include the accounts of the Company and its wholly-owned subsidiaries. All significant inter-company transactions and balances have been eliminated. Use of Estimates Preparing financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period. Such estimates include (i) the amount of allowance for doubtful accounts; (ii) estimates used to determine the merger consideration receivable; (iii) future cash flows used for testing recoverability of property and equipment; (iv) fair values used for testing FCC broadcasting licenses and goodwill for impairment; (v) fair value of assets acquired and given up in the radio station exchange in Boston, MA; (vi) the realization of deferred tax assets, and (vii) actuarial assumptions related to the pension plan, SERP and other postretirement benefits. Actual results and outcomes may differ from management’s estimates and assumptions. Reclassifications Certain amounts previously reported in the 2016 financial statements have been reclassified to conform to the 2017 presentation. Cash and Cash Equivalents All short-term investments with an original maturity of three months or less are considered to be cash equivalents. Accounts Receivable Accounts receivable consist primarily of uncollected amounts due from advertisers for the sale of advertising airtime. The amounts are net of advertising agency commissions and an allowance for doubtful accounts. The allowance for doubtful accounts reflects management’s estimate of probable losses in accounts receivable. Management determines the allowance based on historical information, relative improvements or deteriorations in the age of the accounts receivable and changes in current economic conditions. Interest is not accrued on accounts receivable. Property and Equipment Property and equipment is recorded at fair value in a business combination or otherwise at cost and depreciated using the straight-line method over the estimated useful life of the asset. If an event or change in circumstances were to indicate that the carrying amount of property and equipment is not recoverable, the carrying amount will be reduced to the estimated fair value. Repairs and maintenance are charged to expense as incurred. FCC Broadcasting Licenses FCC broadcasting licenses, including translator licenses, are generally granted for renewable terms of eight years. Renewal costs are generally minor and expensed as incurred. Licenses are tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that the Company’s licenses might be impaired. The Company assesses qualitative factors to determine whether it is more likely than not that its licenses are impaired. If the Company determines it is more likely than not that its licenses are impaired then the Company is required to perform the quantitative impairment test. The quantitative impairment test compares the fair value of the Company’s licenses with their carrying amounts. If the carrying amounts of the licenses exceed their fair value, an impairment loss is recognized in an amount equal to that excess. For the purpose of testing its licenses for impairment, the Company combines its licenses into reporting units based on its market clusters. See Note 5 for changes in the carrying amount of FCC broadcasting licenses for the years ended December 31, 2016 and 2017. The weighted-average period before the next renewal of the Company’s FCC broadcasting licenses is 3.0 years. Goodwill Goodwill is tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that the Company’s goodwill might be impaired. The Company assesses qualitative factors to determine whether it is necessary to perform a quantitative assessment for each reporting unit. If the quantitative assessment is necessary, the Company will determine the fair value of each reporting unit. If the fair value of any reporting unit is less than the carrying amount, the Company will recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The loss recognized will not exceed the total amount of goodwill allocated to the reporting unit. For the purpose of testing its goodwill for impairment, the Company has identified its market clusters as its reporting units. See Note 6 for changes in the carrying amount of goodwill for the years ended December 31, 2016 and 2017. Other Intangibles Other intangibles include acquired advertising contracts and advertiser relationships and are amortized over their respective estimated useful lives. If an event or change in circumstances were to indicate that the carrying amount of other intangibles is not recoverable, the carrying amount will be reduced to the estimated fair value. Investments Other assets include noncontrolling interests in LN2 DB, LLC and Quu, Inc. which are accounted for under the cost method of accounting. Under the cost method of accounting, investments are carried at cost and only adjusted for distributions received in excess of earnings and other-than-temporary declines in fair value. The Company evaluates the investments on a quarterly basis and recognizes an impairment loss if a decline in value is determined to be other-than-temporary. Such impairment evaluations include the current business environment, the investee’s competition, and the investee’s ability to obtain additional financing to achieve its business plan. If the Company has not identified events or changes in circumstances that may have a significant adverse effect on the fair value of the investment, then the fair value of the investments are not estimated, as it is impracticable to do so. As of December 31, 2016 and 2017, the carrying value of the investment in LN2 DB, LLC is $1.0 million and the carrying value of the investment in Quu, Inc. is $0.9 million. Debt Issuance Costs Debt issuance costs are capitalized and amortized over the life of the related debt as interest expense on a straight-line basis which approximates the effective interest method. Unamortized debt issuance costs are reported as a direct deduction from the carrying amount of the related debt. Defined Benefit Plan and Other Postretirement Benefits The costs and liabilities of the defined benefit plan and other postretirement benefits are determined using actuarial valuations. An actuarial valuation involves making various assumptions that include the discount rate, rate of return on plan assets, and mortality rates. The discount rate is based on matching the cash flows of the plan to the Citigroup Pension Discount Curve. The long-term rate of return on plan assets was selected based on input from the investment advisor and publicly available survey information on expected returns by asset class. The mortality assumptions are based on the mortality tables and mortality improvement scales which are selected based on the most recent study of the Society of Actuaries. The pension plan and SERP are both frozen so future employment does not change the benefit amounts. The postretirement medical and life insurance benefits are not impacted by the healthcare cost trend assumption because the reimbursements to retirees are fixed amounts. Actual results will differ from results which are estimated based on assumptions. Treasury Stock Treasury stock is accounted for using the cost method whereby the entire cost of the acquired stock is recorded as treasury stock. Revenue Revenue from the sale of advertising airtime is recognized when commercials are broadcast and collection is reasonably assured. Revenues are reported net of advertising agency commissions, generally 15% of gross revenue, in the financial statements. An estimated allowance is recorded for uncollectible accounts. Payments received before commercials are broadcast are recorded as deferred revenue. Trade sales are recorded at the estimated fair value of the goods or services received. Revenue from trade sales is recognized when commercials are broadcast. Goods or services are recorded when received. If commercials are broadcast before the goods or services are received then a trade sales receivable is recorded. If goods or services are received before the broadcast of commercials then a trade sales payable is recorded. Trade sales revenue was $5.3 million and $9.6 million for the years ended December 31, 2016 and 2017, respectively. Trade sales expenses were $5.1 million and $9.6 million for the years ended December 31, 2016 and 2017, respectively. Stock-Based Compensation The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The cost is recognized in earnings over the period during which an employee is required to provide service. No compensation cost is recognized for equity instruments for which employees do not render the requisite services. Income Taxes The Company recorded income taxes under the liability method. Deferred tax assets and liabilities are recognized for all temporary differences between tax and financial reporting bases of the Company’s assets and liabilities using enacted tax rates applicable to the periods in which the differences are expected to affect taxable income. Tax benefits from an uncertain tax position are only recognized if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. Interest and penalties related to unrecognized tax benefits are recorded as incurred as a component of income tax expense. Comprehensive Income Comprehensive income consists of net income and other gains and losses affecting stockholders’ equity that, under accounting principles generally accepted in the United States of America are excluded from net income, including unrealized gains (losses) on available-for-sale Earnings per Share Basic net income per share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Common shares outstanding include shares of both Class A and Class B common stock, which have equal rights and privileges except with respect to voting. Diluted net income per share reflect the potential dilution that could occur if stock options, restricted stock or other contracts to issue common stock were exercised or converted into common stock and were not anti-dilutive. Concentrations of Risk Certain cash deposits with financial institutions may at times exceed FDIC insurance limits. The radio stations located in Boston, MA and Philadelphia, PA contributed 41.1% of the Company’s net revenue in 2017. The radio stations located in Charlotte, NC and Tampa-Saint Petersburg, FL, contributed 43.5% and 22.1% of the Company’s net revenue in 2016 and 2017, respectively. Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk. Inputs may be observable or unobservable. Observable inputs are based on market data obtained from sources independent of the Company. Unobservable inputs reflect the Company’s own assumptions based on the best information available in the circumstances. The fair value hierarchy prioritizes the inputs used to measure fair value into three broad levels. The three levels of the fair value hierarchy are defined as follows: Level 1 – Inputs are quoted prices in active markets for identical assets or liabilities as of the reporting date. Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, as of the reporting date. Level 3 – Unobservable inputs for the asset or liability that reflect management’s own assumptions about the assumptions that market participants would use in pricing the asset or liability as of the reporting date. Recent Accounting Pronouncements In March 2017, the Financial Accounting Standards Board (“FASB”) issued guidance to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. The new guidance is effective for annual periods beginning after December 15, 2017. The Company adopted the new guidance in the first quarter of 2018 with no material impact on its financial statements. In January 2017, the FASB issued guidance to simplify goodwill impairment testing by eliminating step two from the goodwill impairment test. Under the new guidance, an entity still has the option to perform the qualitative assessment of a reporting unit to determine if the quantitative impairment test is necessary. Under the new guidance an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The new guidance is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. The Company adopted the new guidance on a prospective basis in the first quarter of 2017 with no current impact on its financial statements. In August 2016, the FASB issued guidance to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The Company adopted the new guidance in the first quarter of 2018 with no material impact on its financial statements. In March 2016, the FASB issued guidance to improve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The new guidance is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods. The Company adopted the new guidance in the first quarter of 2017 with no material impact on its financial statements. In February 2016, the FASB issued guidance to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use In January 2016, the FASB issued guidance that changes how entities measure equity investments and present changes in the fair value of financial liabilities. The new guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income unless the investments qualify for the new practicality exception. A practicality exception will apply to those equity investments that do not have a readily determinable fair value and do not qualify for the practical expedient to estimate fair value, and as such, these investments may be measured at cost. The new guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company adopted the new guidance in the first quarter of 2018 with no material impact on its financial statements. In September 2015, the FASB issued guidance that modified accounting for business combinations to reflect measurement period adjustments to be recorded prospectively rather than retroactively to the assets and liabilities initially recorded under purchase price accounting. The guidance, which was effective as of January 1, 2016, did not have a material impact on the Company’s financial statements at the time of adoption. During the first quarter of 2017, the Company accounted for measurement period adjustments on a prospective basis. See Note 3 for further information. In May 2014, the FASB issued guidance to clarify the principles for recognizing revenue. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised 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 provides a comprehensive framework for revenue recognition that supersedes current general revenue guidance and most industry-specific guidance. In addition, the guidance requires improved disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized. In 2016, the FASB issued several updates to address implementation issues and to clarify guidance for principal versus agent considerations and identifying performance obligations and licensing. The Company adopted the new guidance on January 1, 2018, using the modified retrospective method, with no impact on its 2017 financial statements. The cumulative effect of initially applying the new guidance had no impact on the opening balance of retained earnings as of January 1, 2018. The Company does not expect the new guidance to have a material impact on its financial statements in future periods. However, additional disclosures will be included in future reporting periods in accordance with requirements of the new guidance.

Acquisitions and Dispositions	(3) Acquisitions and Dispositions Greater Media Merger On November 1, 2016, (the “Acquisition Date”), the Company completed the acquisition of Greater Media, Inc. (“Greater Media”), pursuant to the merger agreement, dated as of July 19, 2016 by and among the Company, Greater Media, Beasley Media Group 2, Inc., an indirect wholly-owned subsidiary of the Company (“Merger Sub”), and Peter A. Bordes, Jr., as the Stockholders’ Representative (the “Merger Agreement”). On the Acquisition Date, Merger Sub was merged with and into Greater Media, with Greater Media surviving the merger as an indirect wholly-owned subsidiary of the Company (the “Merger”). As a result of the Merger, the Company added 21 radio stations in the Boston, MA, Detroit, MI, Charlotte, NC, Middlesex, NJ, Monmouth, NJ, Morristown, NJ and Philadelphia, PA markets. Pursuant to the terms of the Merger Agreement, at the effective time of the Merger, the Company acquired all of the issued and outstanding common stock of Greater Media for an aggregate purchase price of $239,875,000, subject to a purchase price adjustment related to the sale of Greater Media’s tower assets and other customary post-closing purchase price adjustments and inclusive of the repayment of $82.2 million of Greater Media’s outstanding debt and the payment of certain transaction expenses. The proceeds paid to the stockholders of Greater Media consisted of (i) $94.4 million in cash and (ii) $25.0 million in shares of the Company’s Class A common stock, which equaled 5,422,993 shares at a fixed value of $4.61 per share (the “Merger Shares”). The 5,422,993 shares of Class A common stock were recorded at a fair value of $4.80 per share or $26.0 million on the Acquisition Date. The Merger consideration was subject to adjustment for changes in working capital of Greater Media, outstanding debt of Greater Media and its subsidiaries as of the Acquisition Date and certain other payments and expenses. In addition, the stockholders of Greater Media were to receive the net cash proceeds from the sale of Greater Media’s tower assets, originally estimated to be approximately $24.0 million. The Company incurred transaction expenses of $6.4 million during the year ended December 31, 2016. The acquisition was accounted for as a business combination. The purchase price allocations were based on a valuation of assets and liabilities and the estimates and assumptions were revised as the Company obtained additional information during the measurement period, which was up to one year from the Acquisition Date. On the Acquisition Date, in accordance with the Merger Agreement, the Company placed 867,679 shares of the Company’s Class A common stock with a fair value of $4.2 million in escrow. These escrow shares were to be distributed either to the Company for cancellation or to Greater Media based upon a working capital adjustment. As of the Acquisition Date based on the estimated working capital adjustment, the Company estimated that 189,915 shares of Class A common stock would be released to Greater Media and the remainder would be forfeited to the Company for cancellation. The estimated number of shares to be released to greater Media had a fair value of $0.9 million as of the Acquisition Date and were included in the purchase price. The estimated shares to be forfeited were not indexed to the Company’s stock price and therefore were adjusted to fair value based on the Company’s closing stock price on each reporting date with changes in fair value recorded in earnings. The estimated number of shares to be forfeited had a fair value of $3.3 million as of the Acquisition Date and were reported as merger consideration receivable in the accompanying consolidated balance sheet. The estimated number of shares to be forfeited had a fair value of $4.2 million as of December 31, 2016. Also, in accordance with the Merger Agreement, the purchase price was to be adjusted by certain proceeds from the sale of Greater Media’s towers assets. Based on the proceeds from the tower sale, the former stockholders of Greater Media were required to return a certain number of shares of Class A common stock to the Company for cancellation. The Company accounted for this arrangement as contingent consideration subject to the ultimate sale of the tower assets. As of the Acquisition Date, the Company estimated the sales price of the towers to be $28.0 million which resulted in the expected return of 650,759 shares. As of the Acquisition Date, the estimated number of shares to be returned had a fair value of $3.4 million and were reported as merger consideration receivable in the accompanying consolidated balance sheet. The estimated number of shares to be returned had a fair value of $3.7 million as of December 31, 2016. On February 27, 2017, the former stockholders of Greater Media entered into an asset purchase agreement to sell the towers for $28.0 million. On December 29, 2017, the Company entered into a settlement agreement with Greater Media regarding the working capital adjustment and proceeds from the tower sale. As a result, all 867,679 shares held in escrow for the working capital adjustment will be forfeited to the Company and canceled during the first quarter of 2018 and the former stockholders of Greater Media will return 470,480 shares related to the tower sale proceeds to the Company which will also be canceled during the first quarter of 2018. The shares held in escrow that will be forfeited had a fair value of $11.6 million as of December 31, 2017 and the shares to be returned had a fair value of $6.3 million as of December 31, 2017. The Company has engaged a third party to evaluate certain net operating loss carryforwards related to Greater Media, Inc. and several of its subsidiaries to determine the amount of net operating loss carryforwards that may be utilized by the Company in future tax returns. These evaluations have not been finalized, therefore an estimate of $3.6 million for net operating loss carryforwards has been included in the purchase price. The accounting for this item was not finalized before the end of the measurement period and any adjustment will now be recognized in current operations during the period in which the accounting is finalized. The following table summarizes the purchase price allocation as of the Acquisition Date: Cash and cash equivalents $ 7,683,950 Accounts receivable 29,889,677 Prepaid expenses 1,710,924 Other current assets 541,460 Property and equipment 40,642,648 FCC broadcasting licenses 263,260,200 Other intangibles, net 2,790,524 Other assets 676,632 Accounts payable (429,042 ) Other current liabilities (16,685,309 ) Long-term debt (82,177,895 ) Deferred tax liabilities (76,050,112 ) Other long-term liabilities (13,709,261 ) Net assets acquired 158,144,396 Gain on merger (44,281,066 ) Purchase price $ 113,863,330 The following table summarizes the components of the purchase price: Cash $ 94,444,148 Stock issued 21,865,506 Estimated tower sale adjustment (3,357,916 ) Stock issued in escrow 4,164,859 Estimated working capital adjustment (3,253,267 ) Purchase price $ 113,863,330 The fair value of the property and equipment acquired in the Merger was estimated using cost and market approaches. Property and equipment for which there are comparable current replacements available, such as radio towers, antenna systems, transmitter equipment, and studio equipment, were valued on the basis of a cost approach. The cost approach allowed for factors such as physical depreciation as well as functional and economic obsolescence. Property and equipment for which an active used market exists, including property for which there is no longer comparable current replacements available but for which there remains an active used market, such as furniture, computer equipment, and vehicles, were valued using a market approach. The market approach is based on the selling prices of similar assets on the used market. As few sales reflect identical assets, the selling prices of similar assets was utilized with adjustments made for any differences such as age, condition, and options. The fair value of the FCC broadcasting licenses acquired in the Merger was estimated using an income approach. The income approach measures the expected economic benefits the licenses provide and discounts these future benefits using discounted cash flow analyses. The discounted cash flow analyses assume that each license is held by a hypothetical start-up radio station and the value yielded by each discounted cash flow analysis represents the portion of the hypothetical start-up radio station’s value attributable solely to its license. The discounted cash flow model incorporates variables such as radio market revenues; the projected growth rate for radio market revenues; projected radio market revenue share; projected radio station operating income margins; and a discount rate appropriate for the radio broadcasting industry. The variables used in the analyses reflect historical radio station and market growth trends, as well as anticipated radio station performance, industry standards, and market conditions. The discounted cash flow projection period of ten years was determined to be an appropriate time horizon for the analyses. Stable market revenue share and operating margins are expected at the end of year three (maturity). The key assumptions used in the valuation of the FCC broadcasting licenses are as follows: Revenue growth rates 0.3% - 1.3% Market revenue shares at maturity 12.6% - 48.0% Operating income margins at maturity 15.0% - 31.3% Discount rate 9% Effective on the Acquisition Date, the Company entered into an agreement with the former CEO of Greater Media to provide consulting services for a period of one year. The costs associated with this agreement are reported in other operating expenses in the accompanying statement of comprehensive income for the year ended December 31, 2017. Dispositions On January 6, 2017, the Company completed the sale of substantially all of the assets used or useful in the operations of WBT-AM, WBT-FM, WFNZ-AM WLNK-FM WBT-AM, WBT-FM WLNK-FM WBT-AM, WBT-FM WLNK-FM On May 1, 2017, the Company completed the sale of substantially all of the assets used in the operations of WIKS-FM, WMGV-FM, WNCT-AM, WNCT-FM, WSFL-FM WXNR-FM Greenville-New Greenville-New Greenville-New Greenville-New Greenville-New WIKS-FM, WMGV-FM, WNCT-AM, WNCT-FM, WSFL-FM WXNR-FM Asset Exchange On December 19, 2017, the Company completed an asset exchange with CBS Radio Stations, Inc., Entercom Boston, LLC, and The Entercom Divestiture Trust under which the Company agreed to exchange all of the assets used or useful in the operations of WMJX-FM WBZ-FM The asset exchange was accounted for as a business combination. The fair value of the assets received in the asset exchange was $48.9 million. The fair value of the assets given up in the asset exchange was $48.9 million which includes the FCC broadcasting license with a fair value of $35.9 million, property and equipment with a fair value of $0.7 million, and a cash payment of $12.0 million. The assets of WMJX-FM The asset allocation is summarized as follows: Property and equipment $ 806,970 FCC broadcasting license 35,943,600 Goodwill 11,882,030 Other intangibles 267,400 Fair value of assets received 48,900,000 Less cash consideration (12,000,000 ) 36,900,000 Carrying amount of assets of exchanged radio station (25,096,415 ) Gain on exchange $ 11,803,585 The fair value of the property and equipment was estimated using cost and market approaches. Property and equipment for which there are comparable current replacements available were valued on the basis of a cost approach. The cost approach allowed for factors such as physical depreciation as well as functional and economic obsolescence. Property and equipment for which an active used market exists, including property for which there is no longer comparable current replacements available but for which there remains an active used market were valued using a market approach. The market approach is based on the selling prices of similar assets on the used market. As few sales reflect identical assets, the selling prices of similar assets was utilized with adjustments made for any differences such as age, condition, and options. If different assumptions or estimates had been used in the cost and market approaches, the fair value of the property and equipment could have been materially different. The fair value of the FCC broadcasting licenses were estimated using an income approach. The income approach measures the expected economic benefits the licenses provide and discounts these future benefits using discounted cash flow analyses. The discounted cash flow analyses assume that each license is held by a hypothetical start-up The key assumptions used in the valuation of the FCC broadcasting licenses are as follows: Revenue growth rates (0.5)% - 2.4% Market revenue shares at maturity 5.3% Operating income margins at maturity 36.0% Discount rate 9.0% Goodwill was equal to the amount the purchase price exceeded the values allocated to the tangible and identifiable intangible assets. The $11.9 million allocated to goodwill is deductible for tax purposes. Other intangibles include a sports rights agreement of $0.3 million which will be amortized over its estimated useful life of 3 years. A summary of assets held for sale as of December 31, 2016 is as follows: WFNZ-AM Greenville- New Bern- WMJX Total Property and equipment, net $ 1,702,847 $ 1,400,615 $ 377,193 $ 3,480,655 FCC broadcasting licenses 2,166,400 3,998,940 24,759,640 30,924,980 Goodwill — 1,943,349 — 1,943,349 Other intangibles 108,135 — — 108,135 $ 3,977,382 $ 7,342,904 $ 25,136,833 $ 36,457,119 The following unaudited pro forma information for the years ended December 31, 2016 and 2017 assumes that the acquisitions and dispositions had occurred on January 1, 2016.

The previous revolving credit facility carried interest, based on the London Interbank Offered Rate (“LIBOR”), at 6.8% as of December 31, 2016. The term loan carried interest, based on LIBOR, at 7.0% as of December 31, 2016. On November 17, 2017, the Company, through its wholly-owned subsidiary, Beasley Mezzanine Holdings, LLC, entered into a new credit agreement with a syndicate of financial institutions. Proceeds from the new credit facility were primarily used to repay the previous credit facility. In connection with the new credit agreement, the Company recorded a loss on modification of long-term debt of $4.0 million during the fourth quarter of 2017. As of December 31, 2017, the credit facility consisted of a term loan with a remaining balance of $225.0 million and a revolving credit facility with a maximum commitment of $20.0 million. As of December 31, 2017, the Company had $20.0 million in available commitments under its revolving credit facility. At the Company’s option, the credit facility may bear interest at either (i) LIBOR plus a margin 4.0% or (ii) the base rate plus a margin of 3.0%. The LIBOR interest rate for the term loan is subject to a 1% floor. Interest payments are, for loans based on LIBOR, due at the end of each applicable interest period unless the interest period is longer than three months, in which case they are due at the end of each three month period. Interest payments for loans based on the base rate are due quarterly. The revolving credit facility carried interest, based on LIBOR, at 5.5% as of December 31, 2017 and matures on November 17, 2022. The term loan carried interest, based on LIBOR, at 5.5% as of December 31, 2017 and matures on November 1, 2023. Commencing with the year ending December 31, 2018, the credit agreement requires mandatory prepayments equal to 50% of Excess Cash Flow (as defined in the credit agreement) when the Company’s Total Leverage Ratio (as defined in the credit agreement) is greater than 3.5x; mandatory prepayments equal to 25% of Excess Cash Flow when the Total Leverage Ratio is less than or equal to 3.5x but greater than 3.0x; and no mandatory prepayments when the Total Leverage Ratio is less than or equal to 3.0x. Mandatory prepayments of consolidated Excess Cash Flow are due 95 days after year end. The credit agreement also requires mandatory prepayments for defined amounts from net proceeds of asset sales, net insurance proceeds, and net proceeds of debt issuances. The credit agreement requires us to comply with certain financial covenants which are defined in the credit agreement. These financial covenants include a First Lien Leverage Ratio that will be tested at the end of each quarter beginning with the quarter ending December 31, 2017. For the period from December 31, 2017 through March 31, 2018, the maximum First Lien Leverage Ratio is 6.25x. For the period from June 30, 2018 through December 31, 2018, the maximum First Lien Leverage Ratio is 6.0x. For the period from March 31, 2019 through December 31, 2019, the maximum First Lien Leverage Ratio is 5.75x. The maximum First Lien Leverage Ratio is 5.25x for March 31, 2020 and thereafter. The credit facility is secured by substantially all assets of the Company and its subsidiaries and is guaranteed jointly and severally by the Company and its subsidiaries. If the Company defaults under the terms of the credit agreement, the Company and its subsidiaries may be required to perform under their guarantees. As of December 31, 2017, the maximum amount of undiscounted payments the Company and its applicable subsidiaries would have been required to make in the event of default was $225.0 million. The guarantees for the credit facility expire on November 17, 2022 for the revolving credit facility and on November 1, 2023 for the term loan. Failure to comply with financial covenants, scheduled interest payments, scheduled principal repayments, or any other terms of the credit agreement could result in the acceleration of the maturity of the Company’s outstanding debt, which could have a material adverse effect on the Company’s business or results of operations. As of December 31, 2017, the Company was in compliance with all applicable financial covenants under the credit agreement. The aggregate scheduled principal repayments of the credit facility and capital lease obligations for the next five years and thereafter are as follows: 2018 $ 2,314,020 2019 2,317,101 2020 2,320,326 2021 2,323,700 2022 2,253,332 Thereafter 214,102,395 Total $ 225,630,874

Postemployment Benefits [Abstract]
Employee Benefit Plans	(10) Employee Benefit Plans Defined Contribution Plan The Company has a defined contribution plan that conforms to Section 401(k) of the Internal Revenue Code. Under this plan, employees may contribute a minimum of 1% of their compensation (no maximum) to the Plan. However, the Internal Revenue Code limited contributions to $18,000 (or $24,000 if aged 50 years or older) in 2016 and 2017. No employer matching contributions have been made to the defined contribution plan in 2016 and 2017. On November 1, 2016, the Company merged the Greater Media defined contribution plan into the Company’s defined contribution plan. Defined Benefit Plan On November 1, 2016, the Company assumed the frozen Greater Media defined benefit plan (”Pension Plan”). The projected benefit obligation in excess of the fair value of plan assets of $4.0 million is reported in other long-term liabilities in the balance sheet as of December 31, 2016. The discount rate is based on matching the projected cash flows of the plan to the Citigroup Pension Discount Curve. The mortality assumptions are based on the RP-2014 MP-2014 MP-2016 Supplemental Employee Retirement Plan On November 1, 2016, the Company assumed the frozen Greater Media supplemental employee retirement plan (“SERP”).

In the election of directors, the holders of Class A common stock are entitled by class vote, exclusive of other stockholders, to elect two of the Company’s directors, with each Class A share being entitled to one vote. In the election of the other six directors and all other matters submitted to the stockholders for a vote, the holders of Class A shares and Class B shares shall vote as a single class, with each Class A share being entitled to one vote and each Class B share entitled to ten votes. The Company’s credit agreement permits it to repurchase sufficient shares of its common stock to fund withholding taxes in connection with the vesting of restricted stock, subject to compliance with financial covenants, up to an aggregate amount of $2.5 million per year. The Company paid $1.1 million to repurchase 94,753 shares in 2017. The Company’s credit agreement restricts its ability to pay cash dividends and to repurchase additional shares of its common stock. The credit agreement does permit, however, (i) additional dividends of up to an aggregate amount of $7.5 million each year if its Total Leverage Ratio is greater than 3.5x and up to an aggregate amount of $10.0 million each year if its Total Leverage Ratio is less than or equal to 3.5x, (ii) an amount equal to its excess cash flow each year that is not required to prepay the credit agreement, subject to maintaining a Total Leverage Ratio of no greater than 3.75x and (iii) unlimited dividends each year if its Total Leverage Ratio is less than 3.5x and its First Lien Leverage Ratio is less than 2.5x. The Company paid cash dividends of $4.1 million and $5.1 million in 2016 and 2017, respectively. On December 4, 2017, the Company declared a cash dividend of $0.045 per share on its Class A and Class B common stock.

As of December 31, 2016 and 2017, the Company does not have any material unrecognized tax benefits and accordingly has not recorded any interest or penalties related to unrecognized tax benefits. The Company and its subsidiaries file a consolidated federal income tax return and various state returns. These returns remain subject to examination by taxing authorities for all years after 2013. New Tax Reform Legislation In December 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was enacted. The Tax Act makes significant change in U.S. tax law including a reduction in the corporate tax rates, changes to net operating loss carryforwards and carrybacks, and a repeal of the corporate alternative minimum tax. The Tax Act reduced the U.S. corporate tax rate from the current rate of 35% to 21%. As a result of the Tax Act, the Company was required to revalue deferred tax assets and liabilities at the enacted rate. This revaluation resulted in a benefit of $59.7 million to income tax expense and a corresponding reduction in the deferred tax liability.

Summary of Significant Accoun27

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America and include the accounts of the Company and its wholly-owned subsidiaries. All significant inter-company transactions and balances have been eliminated.
Use of Estimates	Use of Estimates Preparing financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period. Such estimates include (i) the amount of allowance for doubtful accounts; (ii) estimates used to determine the merger consideration receivable; (iii) future cash flows used for testing recoverability of property and equipment; (iv) fair values used for testing FCC broadcasting licenses and goodwill for impairment; (v) fair value of assets acquired and given up in the radio station exchange in Boston, MA; (vi) the realization of deferred tax assets, and (vii) actuarial assumptions related to the pension plan, SERP and other postretirement benefits. Actual results and outcomes may differ from management’s estimates and assumptions.
Reclassifications	Reclassifications Certain amounts previously reported in the 2016 financial statements have been reclassified to conform to the 2017 presentation.
Cash and Cash Equivalents	Cash and Cash Equivalents All short-term investments with an original maturity of three months or less are considered to be cash equivalents.
Accounts Receivable	Accounts Receivable Accounts receivable consist primarily of uncollected amounts due from advertisers for the sale of advertising airtime. The amounts are net of advertising agency commissions and an allowance for doubtful accounts. The allowance for doubtful accounts reflects management’s estimate of probable losses in accounts receivable. Management determines the allowance based on historical information, relative improvements or deteriorations in the age of the accounts receivable and changes in current economic conditions. Interest is not accrued on accounts receivable.
Property and Equipment	Property and Equipment Property and equipment is recorded at fair value in a business combination or otherwise at cost and depreciated using the straight-line method over the estimated useful life of the asset. If an event or change in circumstances were to indicate that the carrying amount of property and equipment is not recoverable, the carrying amount will be reduced to the estimated fair value. Repairs and maintenance are charged to expense as incurred.
FCC Broadcasting Licenses	FCC Broadcasting Licenses FCC broadcasting licenses, including translator licenses, are generally granted for renewable terms of eight years. Renewal costs are generally minor and expensed as incurred. Licenses are tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that the Company’s licenses might be impaired. The Company assesses qualitative factors to determine whether it is more likely than not that its licenses are impaired. If the Company determines it is more likely than not that its licenses are impaired then the Company is required to perform the quantitative impairment test. The quantitative impairment test compares the fair value of the Company’s licenses with their carrying amounts. If the carrying amounts of the licenses exceed their fair value, an impairment loss is recognized in an amount equal to that excess. For the purpose of testing its licenses for impairment, the Company combines its licenses into reporting units based on its market clusters. See Note 5 for changes in the carrying amount of FCC broadcasting licenses for the years ended December 31, 2016 and 2017. The weighted-average period before the next renewal of the Company’s FCC broadcasting licenses is 3.0 years.
Goodwill	Goodwill Goodwill is tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that the Company’s goodwill might be impaired. The Company assesses qualitative factors to determine whether it is necessary to perform a quantitative assessment for each reporting unit. If the quantitative assessment is necessary, the Company will determine the fair value of each reporting unit. If the fair value of any reporting unit is less than the carrying amount, the Company will recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The loss recognized will not exceed the total amount of goodwill allocated to the reporting unit. For the purpose of testing its goodwill for impairment, the Company has identified its market clusters as its reporting units. See Note 6 for changes in the carrying amount of goodwill for the years ended December 31, 2016 and 2017.
Other Intangibles	Other Intangibles Other intangibles include acquired advertising contracts and advertiser relationships and are amortized over their respective estimated useful lives. If an event or change in circumstances were to indicate that the carrying amount of other intangibles is not recoverable, the carrying amount will be reduced to the estimated fair value.
Investments	Investments Other assets include noncontrolling interests in LN2 DB, LLC and Quu, Inc. which are accounted for under the cost method of accounting. Under the cost method of accounting, investments are carried at cost and only adjusted for distributions received in excess of earnings and other-than-temporary declines in fair value. The Company evaluates the investments on a quarterly basis and recognizes an impairment loss if a decline in value is determined to be other-than-temporary. Such impairment evaluations include the current business environment, the investee’s competition, and the investee’s ability to obtain additional financing to achieve its business plan. If the Company has not identified events or changes in circumstances that may have a significant adverse effect on the fair value of the investment, then the fair value of the investments are not estimated, as it is impracticable to do so. As of December 31, 2016 and 2017, the carrying value of the investment in LN2 DB, LLC is $1.0 million and the carrying value of the investment in Quu, Inc. is $0.9 million.
Debt Issuance Costs	Debt Issuance Costs Debt issuance costs are capitalized and amortized over the life of the related debt as interest expense on a straight-line basis which approximates the effective interest method. Unamortized debt issuance costs are reported as a direct deduction from the carrying amount of the related debt.
Defined Benefit Plan and Other Postretirement Benefits	Defined Benefit Plan and Other Postretirement Benefits The costs and liabilities of the defined benefit plan and other postretirement benefits are determined using actuarial valuations. An actuarial valuation involves making various assumptions that include the discount rate, rate of return on plan assets, and mortality rates. The discount rate is based on matching the cash flows of the plan to the Citigroup Pension Discount Curve. The long-term rate of return on plan assets was selected based on input from the investment advisor and publicly available survey information on expected returns by asset class. The mortality assumptions are based on the mortality tables and mortality improvement scales which are selected based on the most recent study of the Society of Actuaries. The pension plan and SERP are both frozen so future employment does not change the benefit amounts. The postretirement medical and life insurance benefits are not impacted by the healthcare cost trend assumption because the reimbursements to retirees are fixed amounts. Actual results will differ from results which are estimated based on assumptions.
Treasury Stock	Treasury Stock Treasury stock is accounted for using the cost method whereby the entire cost of the acquired stock is recorded as treasury stock.
Revenue	Revenue Revenue from the sale of advertising airtime is recognized when commercials are broadcast and collection is reasonably assured. Revenues are reported net of advertising agency commissions, generally 15% of gross revenue, in the financial statements. An estimated allowance is recorded for uncollectible accounts. Payments received before commercials are broadcast are recorded as deferred revenue. Trade sales are recorded at the estimated fair value of the goods or services received. Revenue from trade sales is recognized when commercials are broadcast. Goods or services are recorded when received. If commercials are broadcast before the goods or services are received then a trade sales receivable is recorded. If goods or services are received before the broadcast of commercials then a trade sales payable is recorded. Trade sales revenue was $5.3 million and $9.6 million for the years ended December 31, 2016 and 2017, respectively. Trade sales expenses were $5.1 million and $9.6 million for the years ended December 31, 2016 and 2017, respectively.
Stock-Based Compensation	Stock-Based Compensation The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The cost is recognized in earnings over the period during which an employee is required to provide service. No compensation cost is recognized for equity instruments for which employees do not render the requisite services.
Income Taxes	Income Taxes The Company recorded income taxes under the liability method. Deferred tax assets and liabilities are recognized for all temporary differences between tax and financial reporting bases of the Company’s assets and liabilities using enacted tax rates applicable to the periods in which the differences are expected to affect taxable income. Tax benefits from an uncertain tax position are only recognized if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. Interest and penalties related to unrecognized tax benefits are recorded as incurred as a component of income tax expense.
Comprehensive Income	Comprehensive Income Comprehensive income consists of net income and other gains and losses affecting stockholders’ equity that, under accounting principles generally accepted in the United States of America are excluded from net income, including unrealized gains (losses) on available-for-sale
Earnings per Share	Earnings per Share Basic net income per share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Common shares outstanding include shares of both Class A and Class B common stock, which have equal rights and privileges except with respect to voting. Diluted net income per share reflect the potential dilution that could occur if stock options, restricted stock or other contracts to issue common stock were exercised or converted into common stock and were not anti-dilutive.
Concentrations of Risk	Concentrations of Risk Certain cash deposits with financial institutions may at times exceed FDIC insurance limits. The radio stations located in Boston, MA and Philadelphia, PA contributed 41.1% of the Company’s net revenue in 2017. The radio stations located in Charlotte, NC and Tampa-Saint Petersburg, FL, contributed 43.5% and 22.1% of the Company’s net revenue in 2016 and 2017, respectively.
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk. Inputs may be observable or unobservable. Observable inputs are based on market data obtained from sources independent of the Company. Unobservable inputs reflect the Company’s own assumptions based on the best information available in the circumstances. The fair value hierarchy prioritizes the inputs used to measure fair value into three broad levels. The three levels of the fair value hierarchy are defined as follows: Level 1 – Inputs are quoted prices in active markets for identical assets or liabilities as of the reporting date. Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, as of the reporting date. Level 3 – Unobservable inputs for the asset or liability that reflect management’s own assumptions about the assumptions that market participants would use in pricing the asset or liability as of the reporting date.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2017, the Financial Accounting Standards Board (“FASB”) issued guidance to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. The new guidance is effective for annual periods beginning after December 15, 2017. The Company adopted the new guidance in the first quarter of 2018 with no material impact on its financial statements. In January 2017, the FASB issued guidance to simplify goodwill impairment testing by eliminating step two from the goodwill impairment test. Under the new guidance, an entity still has the option to perform the qualitative assessment of a reporting unit to determine if the quantitative impairment test is necessary. Under the new guidance an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The new guidance is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. The Company adopted the new guidance on a prospective basis in the first quarter of 2017 with no current impact on its financial statements. In August 2016, the FASB issued guidance to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The Company adopted the new guidance in the first quarter of 2018 with no material impact on its financial statements. In March 2016, the FASB issued guidance to improve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The new guidance is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods. The Company adopted the new guidance in the first quarter of 2017 with no material impact on its financial statements. In February 2016, the FASB issued guidance to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use In January 2016, the FASB issued guidance that changes how entities measure equity investments and present changes in the fair value of financial liabilities. The new guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income unless the investments qualify for the new practicality exception. A practicality exception will apply to those equity investments that do not have a readily determinable fair value and do not qualify for the practical expedient to estimate fair value, and as such, these investments may be measured at cost. The new guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company adopted the new guidance in the first quarter of 2018 with no material impact on its financial statements. In September 2015, the FASB issued guidance that modified accounting for business combinations to reflect measurement period adjustments to be recorded prospectively rather than retroactively to the assets and liabilities initially recorded under purchase price accounting. The guidance, which was effective as of January 1, 2016, did not have a material impact on the Company’s financial statements at the time of adoption. During the first quarter of 2017, the Company accounted for measurement period adjustments on a prospective basis. See Note 3 for further information. In May 2014, the FASB issued guidance to clarify the principles for recognizing revenue. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised 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 provides a comprehensive framework for revenue recognition that supersedes current general revenue guidance and most industry-specific guidance. In addition, the guidance requires improved disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized. In 2016, the FASB issued several updates to address implementation issues and to clarify guidance for principal versus agent considerations and identifying performance obligations and licensing. The Company adopted the new guidance on January 1, 2018, using the modified retrospective method, with no impact on its 2017 financial statements. The cumulative effect of initially applying the new guidance had no impact on the opening balance of retained earnings as of January 1, 2018. The Company does not expect the new guidance to have a material impact on its financial statements in future periods. However, additional disclosures will be included in future reporting periods in accordance with requirements of the new guidance.
