What does the Regulatory column show?

It shows the first of these that holds, in this order, which is also the order the column sorts in:

An approval failed

China SAMR failed.

In-depth review or challenge

A second request, a phase 2 review or a challenge: HSR second request.

Waiting period running

HSR wait ends Oct 16.

Waiting period ended, no result filed

HSR wait ended Oct 2, no result.

Pending, with a stage

EU phase 1 review.

Pending, no stage given

2 pending, no stage given.

Only the vote or tender left

Cleared; the vote is left.

Approvals cleared

Approvals cleared, Cleared or not required, or None required.

A dash means the deal has no approval published yet. The Regulatory status filter picks deals by these statuses. Point at the status, or focus it, for the regulatory card: a one-line summary, then each approval with its regulator, its stage in words and dots, its date, a line on what the stage is when its name doesn't say, and the filing it comes from, which opens its quote; then the vote, the tender, the outside date and how far it can move, and a link to the deal page.
