Notes to Consolidated Financial Statements
Deferred Offering Costs, page F-13

6.    We note as of December 31, 2022 the Company had capitalized $3.0 million
of deferred
      offering costs in other noncurrent assets. It appears these costs were
incurred in
      connection with an aborted offering, i.e. not a short postponement.
Deferred costs of an
      aborted offering should not be deferred and charged against proceeds of a
subsequent
      offering. Refer to the guidance in SAB Topic 5:A.

Securities Act, whether or
      not they retain copies of the communication.
