Which assumption or principle requires that all information significant enough to affect decisions of reasonably informed users should be reported in the financial statements? Going concern. Historical cost. Full disclosure. Matching.

The answer is: full disclosure principle

Explanation:

Full disclosure principle in accounting refers to the requirement that businesses are supposed to provide all material information pertaining to their operations to the stakeholders of the business so as to facilitate better decision-making frameworks when evaluating the business.

The going concern principle is based on the assumption that the business will not cease operating in the foreseeable future. The matching principle requires that the expenses incurred in carrying out an economic activity are recorded in the same period as the revenues earned from that activity. The historical cost principle requires assets or liabilities to be recorded at their acquisition value.
