Common Units	Common Units As of December 31, 2020, our board of directors has authorized the issuance of 10 million of our two classes of common units: Class A and Class B. If our related party owner’s percentage ownership falls below 50%, Class A common units are redeemable at our related party owner’s option for up to 20% of vested units. After 25 months from the date of issuance, Class B unitholders may sell Class B units to the Company and the Company may also repurchase Class B units. The purchase price for all units is determined based on a multiplier of annual net income, normalized based on the preceding 3 years. Holders of our common units are entitled to one vote for each percentage of interest held based on vested units. Holders of common units are entitled to distributions from available cash as determined by the board of directors after establishing reserves. Upon a liquidation, Class A unitholders first receive distributions equal to their capital contribution prior to distributions to all unitholders of available assets. During 2018, we effected a 1000 to 1 common unit split. All unit and per unit amounts in these consolidated financial statements have been retroactively adjusted to give effect to the common unit split. During the year ended December 31, 2019, the holder of non-controlling interests in one of the Company’s subsidiaries, Casey Research, exchanged its shares for the Company’s Class A units at approximately fair value. The Company recorded the exchange of shares as an equity transaction and did not recognize any gains or losses as a result.
