Amendment Description	This Amendment No. 1 on Form 10-Q/A (the "Form 10-Q/A") is being filed to amend A. H. Belo Corporation's (the "Company") Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on April 29, 2019, for the quarter ended March 31, 2019 (the "original Form 10-Q"). As previously disclosed on Form 8-K filed on November 20, 2019, the Company will also be filing an amended quarterly report on Form 10-Q/A for the quarterly period ended June 30, 2019. On March 18, 2020, the Company filed an Amendment No. 1 on Form 10-K/A (the "Form 10-K/A") to amend the Form 10-K filed with the Securities and Exchange Commission on March 14, 2019, for the fiscal year ended December 31, 2018. The Form 10-K/A was filed in order to reflect the appropriate timing of the noncash impairment charge for goodwill and long-lived assets associated with the Company's Marketing Services reporting unit and the appropriate methodology for calculation of the valuation allowance within the tax provision for 2018. As a result, this Form 10-Q/A amends the Consolidated Balance Sheet as of March 31, 2019. In connection with the restatement, the Company re-calculated the income tax benefit for the three months ended March 31, 2019. The Company determined using an estimated annual effective tax rate to calculate the income tax benefit for the three months ended March 31, 2019 was appropriate, compared to the discrete year-to-date calculation of income tax expense or benefit used in prior interim periods and in the original Form 10-Q. The Consolidated Statement of Operations was restated to reflect additional income tax benefit primarily resulting from using an estimated annual effective tax rate, a reduction in other income, net for additional interest expense related to uncertain tax positions, and the reversal of amortization expense related to the Marketing Services long-lived assets impairment disclosed in the Form 10-K/A. The use of an estimated annual effective tax rate in determining the income tax benefit and a correction to the calculation of uncertain tax positions resulted in adjustments to deferred income taxes, net, other accrued expense, and other liabilities in the Consolidated Balance Sheet as of March 31, 2019. See the Notes to the Consolidated Financial Statements, Note 2 – Restatement of Financial Statements, for additional information. In connection with the identification of these issues that led to the restatements described in this Form 10-Q/A, management of the Company re-evaluated the effectiveness of the Company's disclosure controls and procedures as of the end of the period covered by this report. As a result, management concluded that as of the end of the period covered by this report, due to material weaknesses in internal control over financial reporting described in Management's Report on Internal Control Over Financial Reporting in the Company's Annual Report on Form 10-K/A for the year ended December 31, 2018, the Company's disclosure controls and procedures were not effective. See Part I, Item 4. Except for the items noted herein, no other changes have been made to the original Form 10-Q. This Form 10-Q/A has not been updated for events occurring after the filing of the original Form 10-Q and no attempt has been made in this Form 10-Q/A to modify or update other disclosures as presented in the original filing of the Form 10-Q, except as disclosed in Note 14 – Subsequent Events and Part II, Item 1A. Risk Factors. The following sections have been amended as a result of the restatement: • Part I, Item 1. Financial Information • Part I, Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations • Part I, Item 4. Controls and Procedures No other significant changes have been made to the original Form 10-Q except: • Conforming the cover page to the Securities and Exchange Commission Form 10-Q, updated May 2019 • The updating throughout this report of references to Form 10-Q to Form 10-Q/A • The re-numbering throughout this report of references to the Notes to the Consolidated Financial Statements to reflect the addition of Note 2 In accordance with applicable SEC rules, this Form 10-Q/A includes certifications from our Chief Executive Officer and Principal Financial Officer dated as of the date of this filing.
