As has been widely reported, the government shut down after funding expired at 12:01 a.m. ET today. While we hope this is short-lived, here is information about the implications of the shutdown on the SEC's operations:
SEC Homepage:
SEC Operating Status
Should there be a federal government shutdown after January 19, the SEC will remain open for a limited number of days, fully staffed and focused on the agency's mission.
Any changes to the SEC's operational status will be announced here. In the event that the SEC does shut down, we will pursue the agency's plan for operating during a shutdown. As that plan contemplates, we are currently making preparations for a potential shutdown with a focus on the market integrity and investor protection components of our mission.
Among many other things, the SEC's Operations Plan Under a Lapse in Appropriations and Government Shutdown addresses the impact of the shutdown on Edgar-related or dependent services and filings (page 12), and the SEC's review of periodic reports and other filings and registration statements (page 16).
