| Amendment Description | This Amendment No. 1 to Form 10-K (this “Amendment”) amends the Annual Report on Form 10-K for the fiscal year ended December 31, 2019 (the “2019 Form 10-K”) originally filed on February 21, 2020 (the “Original Filing”) by WABCO Holdings, Inc., a Delaware corporation (“WABCO,” the “Company,” “we” or “us”). We are filing this Amendment to present the information required by Part III of Form 10-K and to re-file required updated certifications under Section 302 of the Sarbanes-Oxley Act of 2002. Because no financial statements are contained within this Form 10-K/A, the Company is not including the individual certification pursuant to Section 302 regarding financial statements, regarding disclosure control procedures, or regarding internal controls over financial reporting. Additionally, because no financial statements are contained within this Form 10-K/A, the Company is not required to file the certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002. On March 28, 2019, WABCO entered into an Agreement and Plan of Merger with ZF Friedrichshafen AG, a stock corporation organized and existing under the laws of the Federal Republic of Germany, pursuant to which ZF will acquire 100% of the issued and outstanding shares of WABCO common stock (the Merger). The Merger is expected to close in the first half of 2020, subject to customary closing conditions, including the receipt of required regulatory approvals. Except as described above, no other changes have been made to the Original Filing. The Original Filing continues to speak as of the date of the Original Filing, and we have not updated the disclosures contained therein to reflect any events which occurred at a date subsequent to the filing of the Original Filing. | ||
