What's included

Know who reports, what they hold, and when each Form is due.

Each answer is recorded with its date.

A Section 16 person's designation on the roster

Know which Form applies

Form 3, 4, or 5 is identified automatically from each person's roster designation and the type of transaction.

Holdings listed by person, security, and ownership form

Track holdings by person and security

Track the reported balance per person, security, and ownership form. Opening holdings come from the Forms already filed on EDGAR, and every later change and reconciliation is kept.

A Form deadline shown with its rule

See each deadline's rule

Each Form deadline is calculated on the federal or NYSE calendar and stored with the holiday it skipped. Every due date comes with its reason.

How it works

Switch it on. Report as it happens.

Add Section 16 to the roster you already keep, so nothing is set up twice.

1

Switch on reporting

Turn Section 16 on for any US or UK roster with one issuer setting. Switch it off to hide everything, including the Section 16 pages.

2

Import holdings

Import each person's last filed Form from EDGAR as SEC XML, then review the opening position against your own records before the first transaction.

3

Report each transaction

A cleared trade or a grants file becomes a reportable transaction with its Form and deadline, and your filing agent receives a reviewed draft.

In depth

Record each transaction through to the filed Form.

Evidence of every step is kept, so you answer any question with a report, not a search.

Confirm your transaction prompt shown after a person confirms a trade

Review each change in holdings

When a Section 16 person confirms they made a cleared trade, they are asked to confirm the details.

Every row of your plan administrator's grants and vestings CSV is validated before it loads.

Indirect lines name the related person or entity, and derivative and award classes are securities in their own right for Table II of Form 4.

A Form 4 filing row with its due date and the rule and holiday behind it

Review the Form and its deadline.

Each Form is identified from the person's role, the effective date, and the type of transaction.

Every deadline is calculated on the federal EDGAR or NYSE calendar and stored with its rule, its inputs, and the holidays skipped.

An authorized person can move a date with a reason, and both dates stay on the filing.

A filing's status strip from sent to acknowledged to filed, with the accession number and matching balances

Send the draft and check the filed Form

You send a versioned draft Form to your filing agent once it passes validation and your reviewer's sign-off.

When the agent returns the accession number and balances, each is compared automatically with the recorded holdings. A mismatch is flagged and assigned to someone.

Each filed Form carries its Rule 16a-3(k) posting deadline and the date it can come down, 12 months later.

First page of a person report

Show each director their own holding.

Each director sees their holding, open Forms, and deadlines in the portal, so nobody needs to email you for them.

A UK or European company listed in the US adds Section 16 to the roster it already keeps, and nothing on the UK side changes.

Export each person's report in date order to PDF or Excel.

Onboarding

Start from your last filed Form.

Opening positions come from the Forms already on EDGAR, and you review them against your records before the first transaction.

Opening positions imported from a filed Form

Import opening balances from EDGAR

Import each person's last filed Form 3, 4, or 5 as SEC XML and review it against your records. You start from what is already filed.

People and broker accounts loaded through the roster

Upload people and broker accounts

Designations, effective dates, and broker accounts load through the roster's CSV template, and you can re-upload without creating duplicates. One list serves roster and reporting.

A grants file validated row by row

Load grants and vestings in bulk

Your plan administrator's grants and vestings load as transactions in the right class of security, and every row is validated. No retyping.

A correction entry with its reason and author

Sign off the opening reconciliation

Sign off each opening position before the first transaction. Balances are never edited, so a difference becomes a correction entry with its reason and author.
