A company exited but there is still unrealized value shown. Why?

When a company is acquired, the acquirer often holds back some portion of the purchase price in order to satisfy contingencies.

Common examples of this are indemnification escrows and milestone-based payments.

These portions of the exit consideration are often realized over several years following the exit.

In some exits, part of the exit proceeds consist of stock in a private company acquirer. In these cases, the acquirer stock may remain unrealized for many years.
