Updated Special Purpose Acquisition Company (SPAC) Taxonomy

July 22, 2025

Today, Staff published an updated SPAC taxonomy at Standard Taxonomies: Operating Companies. The updated taxonomy will be deployed as part of a forthcoming EDGAR Release and will include the following changes:

  • Add the Over-allotment Option [Axis] to the dilution source link roles relating to SPAC dilution disclosure.
  • Replace the Security Class [Axis] in certain roles relating to sponsor compensation with Compensation Nature [Axis] (logically a superset of Security Class [Axis]) so that filers can declare members needed for tagging non-security types of compensation.
  • Add the following standard members to the Dilution Source domain based on additional observations of live filings:
    • Deferred Underwriting Commissions [Member]
    • Upfront Underwriting Fees [Member]
    • Overallotment Liability [Member]
    • Ordinary Shares Forfeited or Cancelled [Member]
  • Deprecate the current Underwriting Fees [Member] in favor of distinct Deferred and Upfront Underwriting Fees members.
