(the &#8220;Company) for the fiscal year ended December 31, 2019, originally filed with the Securities and Exchange Commission (&#8220;SEC&#8221;) on March 10, 2020 (the &#8220;Original Report&#8221;). The purpose of this Form 10-K Amendment is solely to disclose that the Company had filed its Definitive Proxy Statement (the &#8220;Proxy Statement&#8221;) for its 2020 Annual Meeting of Stockholders (the &#8220;2020 Annual Meeting&#8221;), which included the information omitted from the Original Report pursuant to General Instruction G(3) to Form 10-K (the &#8220;Part III Information&#8221;), beyond the deadline for which the Company was required to either file its Proxy Statement or an amendment to its Original Report to include the Part III Information in reliance on the filing extension provided by the U.S. Securities and Exchange Commission&#8217;s Order under Section 36 of the Securities Exchange Act of 1934, as amended, dated March 25, 2020 (Release No. 34-88465) (the &#8220;Order&#8221;).</p>

Consistent with the Company&#8217;s statements in the April 27 Form 8-K, the Company was unable to file the Proxy Statement, including the Part III Information, until May 8, 2020, due to circumstances related to the COVID-19 pandemic. In particular, the service provider that was to handle full set deliveries of the Company&#8217;s Proxy Statement had shortly before the date of the April 27 Form 8-K advised the Company that it might not be able to perform the mailing when scheduled because it had to close its facilities due to an exposure to COVID-19. As a result, the Company was required to change to notice and access delivery, which necessitated rescheduling the date of the 2020 Annual Meeting to June 23, 2020, to provide adequate advance notice prior to the meeting.</p>
