For Operating Companies: The SEC final rule phases in over three years. Large accelerated filers start with their first fiscal period ending on or after June 15, 2019; accelerated filers with their first fiscal period ending on or after June 15, 2020; and all other filers (including foreign private issuers) with their first fiscal period ending on or after June 15, 2021. Regardless of phase, all filers comply beginning with the first 10-Q submitted after the compliance date. Read a Q&A on Inline XBRL requirements based on informal SEC discussions.
For Funds: Fund compliance also phases in over three years but will start later: large fund groups (net assets of $1 billion or more as of the end of their most recent fiscal year) comply two years after the effective date of the amendments; and all other funds comply three years after the effective date of the amendments. The 15 business day filing period for risk/return summary XBRL data is eliminated. Read a Q&A on the rule and implementation based on informal SEC discussions.
