    <dei:AmendmentDescription contextRef="P01_01_2019To12_31_2019"> This Amendment No.&#160;1 on Form 10-K/A (this &#x201c;Amendment&#x201d;) amends our Annual Report on Form 10-K for the fiscal year ended December&#160;31, 2019, originally filed on February&#160;28, 2020 (the &#x201c;Original Filing&#x201d;). We are filing this Amendment to include the information required by Part III and not included in the Original Filing, as we do not intend to file a definitive proxy statement for an annual general meeting of shareholders within 120 days of the end of our fiscal year ended December&#160;31, 2019. In addition, in connection with the filing of this Amendment and pursuant to the rules of the Securities and Exchange Commission (the &#x201c;SEC&#x201d;), we are including with this Amendment new certifications of our principal executive officer and principal financial officer pursuant to Section&#160;302 of the Sarbanes-Oxley Act of 2002. Accordingly, Item 15 of Part IV has also been amended to reflect the filing of these new certifications.  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.  As used in this Amendment, unless the context requires otherwise, the &#x201c;Company,&#x201d; &#x201c;Mylan,&#x201d; &#x201c;our,&#x201d; and &#x201c;we&#x201d; mean Mylan N.V. and its consolidated subsidiaries, &#x201c;NASDAQ&#x201d; means The NASDAQ Global Select Stock Market, and &#x201c;U.S. GAAP&#x201d; means accounting principles generally accepted in the United States (&#x201c;U.S.&#x201d;).  On July&#160;29, 2019, Mylan, Pfizer Inc. (&#x201c;Pfizer&#x201d;), Upjohn Inc. (&#x201c;Upjohn&#x201d;), a wholly-owned subsidiary of Pfizer, and certain other affiliated entities entered into a Business Combination Agreement pursuant to which the Company will combine with Pfizer&#x2019;s Upjohn Business (the &#x201c;Upjohn Business&#x201d;) in a Reverse Morris Trust transaction (the &#x201c;Combination&#x201d;). Upjohn will be the parent entity of the combined Upjohn Business and Mylan business and will be renamed &#x201c;Viatris&#x201d; effective as of the closing of the Combination. The consummation of the Combination is subject to various customary closing conditions, including receipt of regulatory approvals and approval of the Combination by Mylan&#x2019;s shareholders, and is anticipated to close in the second half of 2020.  </dei:AmendmentDescription>
