PPG Annual Report and 10K 2019

36 2019 PPG ANNUAL REPORT AND 10-K Management Report Responsibility for Preparation of the Financial Statements and Establishing and Maintaining Adequate Internal Control Over Financial Reporting We are responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2019. In making this evaluation, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework (2013) . Based on this evaluation we have concluded that, as of December 31, 2019, the Company’s internal control over financial reporting were effective. PricewaterhouseCoopers LLP, an independent registered public accounting firm, has issued their report, included on pages 34-35 of this Form 10-K, regarding the Company’s internal control over financial reporting.
