Focus LLC Common Units
As of December 31, 2020, Focus LLC had 20,661,595 common units that had a corresponding share of the Company’s Class B common stock outstanding.
Each common unit holder and incentive unitholder of Focus LLC (other than the Company), subject to certain limitations, has the right to cause Focus LLC to redeem all or a portion of their vested common units and vested incentive units (“Exchange Right”). Upon an exercise of an Exchange Right with respect to vested incentive units, such incentive units will first be converted into a number of common units that takes into account the then-current value of the common units and such incentive units’ aggregate hurdle amount. Upon an exercise of an Exchange Right with respect to vested common units, and immediately after the conversion of vested incentive units into common units, Focus LLC will acquire each tendered common unit for, at its election, (i) one share of Class A common stock, subject to conversion rate adjustments for stock splits, stock dividends, reclassification and other similar transactions, or (ii) an equivalent amount of cash. In addition, in connection with any redemption of vested common units (other than common units received upon a conversion of incentive units as described in this paragraph), the corresponding shares of Class B common stock will be cancelled. Alternatively, upon the exercise of any Exchange Right, the Company (instead of Focus LLC) will have the right to acquire each tendered common unit (and corresponding share of Class B common stock, as applicable) from the exchanging unitholder for, at its election, (i) one share of Class A common stock, subject to conversion rate adjustments for stock splits, stock dividends, reclassification and other similar transactions, or (ii) an equivalent amount of cash. The Exchange Rights are subject to certain limitations and restrictions intended to ensure that Focus LLC will continue to be treated as a partnership for U.S. federal income tax purposes.
