Fair value of financial instruments |
16. Fair value of financial instruments
Assets and liabilities recorded on a recurring basis in the balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values.
The Company’s financial instruments and investments that are carried at fair value consist mainly of Level 3 assets. Level 3 assets that have been measured on a recurring basis during 2022 relate to the Company’s investments in (i) Convertible Notes of Flotek, designated as trading securities up to the acquisition date of Flotek and (ii) the equity method investment in BPC, for which we elected the fair value option, as described in Note 14 – Acquisitions and investments for disclosure of the terms of these investments. The Company did not have any assets or liabilities measured at fair value using Level 2 of the fair value hierarchy at June 30, 2022. We had no Level 2 or Level 3 assets or liabilities as of December 31, 2021. The estimated fair value of the BPC investment as of June 30, 2022 was determined using a combination of the market and income approaches.
The following table sets forth the fair value of the Company’s financial instruments within Level 3 of the fair value hierarchy.

The key inputs into the Monte Carlo simulation used to estimate the fair value the Convertible Notes were as follows:
