Secretary of State Variations to the SEC
The Secretary of State (SoS) may direct variations to SEC provisions. Such variations are not subject to the SEC Section D: Modification Process, but may still vary existing provisions in the SEC.
A log of all the SoS directed variations to date can be found on the SoS Variations to the SEC webpage.
For information on how the SEC and supporting documentation is developing prior to SoS designation, please see The Developing SEC sub-page.
