## When to use it

Use when both notifications may have been received and the team needs the statutory waiting-period rules. Do not use it to say that the parties may close.

## Used for these tasks

## How AI may be used

Yellow: the lawyer counts the days from the facts and decides whether anyone may close.

**AI may:**

- Record the start rule, the 30th day, the 15th day for a cash tender offer, and the early-termination sentence.
- Record the extension of not more than 30 days, or 10 days for a cash tender offer, including the alternative where the request is not fully complied with.
- Point back to the threshold list for whether the statute applies at all.

**AI must not:**

- Do not state a date on which the parties may close.
- Do not draft a response to a request for additional information.
- Do not state a current civil penalty. Subsection (g)(1) prints $10,000 a day, and no adjusted figure was opened.

**The lawyer checks:**

- Confirm the date the Commission and the Assistant Attorney General received the filings from the persons the statute names.
- Count any extension from the date the agency receives the response described in subsection (e)(2).
- Check whether early termination was granted and published, rather than assuming it.
