Management accounting refers to the provision of financial and non-financial information within organizations to help managers and other employees create value through the effective use of resources. It is concerned with providing information for planning and control, to manage the reduction of waste, and to monitor and manage organizational strategies. This can be compared with financial accounting, which is concerned with the provision of information for interested parties external to the organization, including investors and potential investors and government authorities. Prior to the 1990s, management accounting was defined more narrowly.
