Updated Special Purpose Acquisition Company (SPAC) Taxonomy
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.
