Float time in finance (also public float) is an investment indicator expressed as a percentage and is the ratio of shares remaining in free public circulation to all shares issued by the enterprise. Free float is a distributed shareholding structure of a given public enterprise. The free float ratio determines what percentage of shares in a listed company is in free float, that is, for individual investors who make up distributed shareholding, with less than 5% of the share capital of the company.
Float time in project management has two forms:
- total float - called also simply float is the late start time takeaway early start time - how much time we can delay the task
- free float - can occur when multiple tasks are predecessors of one task. In that case some of tasks can have additional reserve: early start of successor minus early finish of predecessor.
