| Amendment Description | Hannon Armstrong Sustainable Infrastructure Capital, Inc. ("the Company") is filing this amendment (the “Amendment”) to the Form 8-K filed with the Securities and Exchange Commission on July 2, 2020 (the “Original 8-K”). The Original 8-K stated that the financial statements and the pro forma financial information required by Item 9.01 of Form 8-K would be filed by amendment to the Original 8-K within 71 days after the date on which the Original 8-K was filed. The Company has subsequently determined that the acquisition was not significant and such financial statements and pro forma financial information are not required and therefore is amending and restating Item 9.01 of the Original 8-K to eliminate the references to the potential subsequent filing of financial statements and pro forma financial information. |
