Amendment Description	This Amendment No. 1 on Form 10-Q/A (“Amendment No. 1”) amends our Quarterly Report on Form 10-Q for the three and six months ended December 31, 2018, as filed with the U.S. Securities and Exchange Commission on October 9, 2019 (the “Original Filing” and the “Original Filing Date”). This Amendment No. 1 is being filed to include additional discussion around the non-investigatory financial adjustments disclosed in Note 2, “Restatement of Consolidated Financial Statements” and to include the label “as restated” for the financial statements and tabular footnote disclosures impacted by the restatements discussed in the Original Filing. Pursuant to Rule 12b-15 promulgated under the Securities Exchange Act of 1934, as amended, we have included the entire text of Part I, Item 1 in this Amendment No. 1. Part II, Item 6. has been included herein to reflect new certifications pursuant to Section 302 and Section 906 of the Sarbanes-Oxley Act of 2002, which are filed and furnished herewith, respectively. Because this Amendment No. 1 does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 4 and 5 of the certifications pursuant to Section 302 have been omitted. Except as indicated in this Explanatory Note, no other changes were made to the Original Filing. This Amendment No. 1 speaks as of the Original Filing Date, and does not reflect events that may have occurred subsequent to the Original Filing Date.
