Answer: Managerial Accounting
Explanation:
Managerial accounting refers to the preparation of reports and analysis from the company's accounting information to enable managers decide the ways to go with a company.
This type of accounting is for internal use and so is not subject to the kind of scrutiny that financial accounting gets from accounting bodies such as IASB and the FASB.
An example would be the Supply Manager may ask for a report to be made showing them the increase in supply costs for the past decade from their preferred supplier to enable them make a decision on if to find a new supplier.
