Equity investments
The Company periodically invests in non-marketable equity securities of private companies without a readily determinable fair value to promote business and strategic objectives. The securities are carried at cost minus impairment, if any, plus or minus changes resulting from observable process changes in orderly transactions for identical or similar transactions of the same issuer. These securities included Series A-1 and A-2 Preferred Stock in iVexSol, Inc. carried at $4.1 million for the periods ending March 31, 2024 and December 31, 2023, and Series E Preferred Stock in PanTHERA CryoSolutions, Inc. carried at $1.0 million as of March 31, 2024 and December 31, 2023.
