What it is:
A war chest is the cash set aside to deal with unexpected changes in a business environment or to take advantage of a sudden opportunity.
How it works/Example:
Uncertainties, unexpected events and opportunities occur regularly in business environments. In most cases, these events cost money or jeopardize revenues. The ability of a business to handle these unexpected cash needs may mean the difference between success and failure, between new growth and missed opportunities. For example, a business may use a war chest to attempt a takeover of a competitor.
