Delek US Holdings, Inc. 10-Q

ITEM 4. CONTROLS AND PROCEDURES Our disclosure controls and procedures are designed to provide reasonable assurance that the information that we are required to disclose in reports we file under the Securities Exchange Act of 1934, as amended ("the Exchange Act"), is accumulated and appropriately communicated to management. We carried out an evaluation required by Rule 13a-15(b) of the Exchange Act, under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures at the end of the reporting period. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the reporting period. There have been no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred during the third quarter of 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Although most of our corporate employees have shifted to a remote working environment due to the COVID-19 Pandemic, we have not experienced a material impact to our internal control over financial reporting. We are continually monitoring and assessing the COVID-19 Pandemic to minimize the impact on the design and operating effectiveness of our internal controls. 80 | Legal Proceedings, Risk Factors, Unregistered Sales of Equity Securities and Other Information Part II - OTHER INFORMATION
