Organization Consolidation And Presentation Of Financial Statements [Abstract]

Note 2. Basis of Presentation

The consolidated financial statements included in this report reflect all normal and recurring adjustments which, in the opinion of management, are necessary for a fair presentation of our consolidated financial position at September 30, 2020 and December 31, 2019, the consolidated results of operations for the three and nine months ended September 30, 2020 and 2019, and consolidated cash flows for the nine months ended September 30, 2020 and 2019. The unaudited results of operations for the interim periods reported are not necessarily indicative of results to be expected for the full year.

The consolidated financial statements were prepared in accordance with the requirements of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain notes or other financial information that are normally required by U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted from these interim consolidated financial statements. These financial statements, therefore, should be read in conjunction with the financial statements and related notes included in the Company’s annual report on Form 10‑K for the year ended December 31, 2019.

Accordingly, our consolidated financial statements prior to the acquisition date were retrospectively recast to include the financial results of HIP. See Note 3, Acquisitions.
