Organization Consolidation And Presentation Of Financial Statements [Abstract]

Note 2. Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”). In the opinion of management, all adjustments (consisting of normal, recurring adjustments) considered necessary for a fair presentation of the Company’s financial position and results of operations have been included for the periods presented herein. The notes that follow are an integral part of the Company’s consolidated financial statements.

Certain prior period amounts have been reclassified to conform to the current period presentation, the effect of which was not material to the Company’s consolidated financial statements. Specific to the Company’s acquisition of Southern Ionics Minerals, LLC (“SIM”) in the third quarter of 2019, a previously deferred acquisition-related installment payment of $10 was made in the third quarter of 2020 and classified as cash used for investing activities on the Company’s consolidated statements of cash flows for the nine months ended September 30, 2020.
