Explanation:
A claim is an assertion or a statement that something or an event is correct as stated. A claim may not be true. It is therefore subject to proof. That is why claims usually require evidence to substantiate them. For instance, in preparing a set of financial statements, the principal officers (the chief executive and the chief financial officers) make assertions (claims) that the information presented therein is factual, fair, and truthful, etc. Such assertions remain mere claims until they are proved to be true. This is why external auditors, who are supposedly, independent of the management of the company, are expected to confirm or disconfirm such claims before the financial statements can be relied upon for any decision.
