What is an undisturbed price?

What it means and how to read it on a deal.

What it is

A reference close for where the target's shares traded before the deal, taken on a day set by a fixed rule.

How to read it

The checklist shows the price and the day it is from, with the filing's words when a filing states that close.

The day is the last trading day before the earliest official disclosure, in a press release or an SEC filing by a bidder or the target, of a proposal naming a price for all the shares, by any bidder in the process that led to this agreement. Without one, it is the last trading day before the deal's announcement. A disclosure after the market closed keeps that day's close. Later revisions, strategic reviews, the launch of a sale, leaks and press reports don't move it, so the price can already reflect them.

The deal maths use it as a reference price if the deal breaks, not a prediction of where the shares will trade.
