[1] (1) The fair value of Synlogic, Inc. warrants is calculated as the quoted price of the underlying common stock, less the unpaid exercise price of the warrants.

[2] (2) Marketable equity securities classified as Level 2 reflect a discount for lack of marketability due to regulatory sales restrictions.

[3] (3) The fair value of Private Placement Warrants classified as Level 2 is equivalent to that of Public Warrants as the transfer of Private Placement Warrants to anyone other than the initial purchasers or any of their permitted transferees results in the Private Placement Warrants having substantially the same terms as the Public Warrants.
