FAIR VALUE MEASUREMENTS

Financial Instruments

Investments

We retained an interest in CSI Compressco representing approximately 3.7% of CSI Compressco’s outstanding common units as of March 31, 2023 and in December 2021, we invested in a $5.0 million convertible note issued by CarbonFree. In addition, we receive cash and stock of Standard Lithium under the terms of our arrangements as noted in Note 5 - “Investments.”

Our investments in CSI Compressco and Standard Lithium are recorded in investments on our consolidated balance sheets based on the quoted market stock price (Level 1 fair value measurements). The stock component of consideration received from Standard Lithium is initially recorded as unearned income based on the quoted market price at the time the stock is received, then recognized in income over the contract term. Changes in the value of stock are recorded in other (income) expense, net in our consolidated statements of operations.

Our investment in CarbonFree is recorded in our consolidated financial statements based on an internal valuation with assistance from a third-party valuation specialist (a Level 3 fair value measurement). The valuation is impacted by key assumptions, including the assumed probability and timing of potential debt or equity offerings. The convertible note includes an option to convert the note into equity interests issued by CarbonFree. The change in the fair value of the embedded option is included in other (income) expense, net in our consolidated statements of operations. The change in the fair value of the convertible note, excluding the embedded option, is included in other comprehensive income (loss) in our consolidated statements of comprehensive income. The change in our investment in CarbonFree for the three-month period ended March 31, 2023 is as follows:
