Introduction
For the SEC reporting team, Item 408 of Regulation S-K is a paragraph in the Form 10-Q and a couple of items in the Form 10-K, small on the page and entirely dependent on work done elsewhere before the drafting starts. The disclosure itself is mechanical once the facts are settled. The risk is that the facts are not settled when the filing calendar says they must be. What Item 408 requires, quarter by quarter, is set out in [The Item 408 disclosure workflow]. This piece covers the reporting team's half: turning the quarter's plan events into filed, tagged disclosure that is true.
What you need before drafting
Item 408(a) asks whether any director or officer (as defined for Section 16 purposes) adopted or terminated a Rule 10b5-1 trading arrangement or a non-Rule 10b5-1 trading arrangement during the quarter. Modifications count too, because a change to the amount, price or timing of trades under a plan is treated as terminating the old plan and adopting a new one. Where an event occurred, you disclose the material terms: the person's name and title, which type of arrangement it is, the date of adoption or termination, the plan's duration, and the aggregate number of securities to be bought or sold. Pricing terms are the one material term you may leave out.
None of that originates with the reporting team. It comes from whoever administers the plan register, usually legal or compliance. What you need from them is not raw broker paperwork but a reviewed, closed event set for the quarter, with someone's sign-off that it is complete. A confirmed event list you can draft from is a disclosure. A pile of confirmations you have to reconcile at deadline is a scramble.
Quarters with no activity
A quarter with no reportable activity still needs a sentence. Because Item 408(a) asks whether any director or officer acted, issuers routinely state affirmatively that none did, and that is the sentence with the quiet risk. It is easy to write, yet it is only true if someone actually confirmed that no director or officer touched a plan that quarter. Treat "none this quarter" as a fact you received under sign-off, not an assumption made because nothing crossed your desk. The sentence is short. Being certain it is true is the whole job.
Tagging and placement
Item 408 disclosures must be tagged in Inline XBRL (eXtensible Business Reporting Language) like the rest of the filing. Build the tagging into the normal 10-Q and 10-K workflow rather than treating it as a late add-on, and reconcile the tagged values against the reviewed event set so the marked-up numbers match the narrative. Placement is routine once the content is fixed: the quarterly disclosure sits in Part II, Item 5 of the 10-Q, and the fourth quarter's goes in Item 9B of the 10-K rather than in a separate filing.
Annual policy exhibit
Item 408(b) is the annual piece, disclosed in the 10-K or in the proxy statement incorporated into it. It asks whether the company has adopted insider trading policies and procedures reasonably designed to promote compliance with insider trading laws and listing standards. If it has, the policy is filed as Exhibit 19 to the 10-K, even where the narrative disclosure is incorporated from the proxy. If it has not, the company must explain why not.
For the reporting team, the recurring hazard is exhibit hygiene. The version filed must be the version actually in force (and the version your covered persons acknowledged), not last year's file pulled forward out of habit. Confirm the current policy with its owner before it goes into the exhibit index. A stale exhibit is a discrepancy anyone can find by comparing two filings.
Who owns what
This division of labour is worth naming. The completeness of the quarter's plan events, and the sign-off that the register is closed, belong to the team that administers the plans. The drafting, tagging, exhibit assembly and filing belong to the reporting team and the tools that produce your filings. Item 408 closes as a review, not a reconstruction, only when the first team hands the second a set it can rely on. That hand-off is the control; the deadline just tells you when it has to be done.
InsiderList assembles the quarter's disclosable plan events from the plan register, records the completeness review and its sign-off, and exports structured, taxonomy-ready data for the reporting team. The drafting, tagging and filing stay with your reporting team and the tools that produce your filings. Your provider files. Your counsel reviews.
