In sharp contrast to financial accounting, managerial accounting information is intended to serve the specific needs of management. Business managers are charged with business planning, controlling, and decision making. As such, they may desire specialized reports, budgets, product costing data, and other details that are generally not reported on an external basis. Further, management may dictate the parameters under which such information is to be accumulated and presented. For instance, GAAP may require that certain research costs be deducted immediately in computing a business’s externally reported income; on the other hand, management may see these costs as a long-term investment and stipulate that internal decision making be based upon income numbers that exclude such costs. This is their prerogative. Hopefully, such internal reporting is being done logically and rationally, but it need not follow any particular set of guidelines.
