Films on Demand Managerial accounting is used to provide sound quantitative support for HCO decision-makers. Although data are not perfect and assumptions are sometimes not accurate, accountancy has rules and procedures—such as generally accepted accounting principles (GAAP)—that seek to produce objective outcomes. This video is 15 minutes in length and covers the basic accounting definitions, principles, and rules such as GAAP. The difference between debits and credits is covered as well as the different types of accounts, journalizing, and posting transactions. Finally, the video contrasts three different types of organizations and how their recording of transactions may appropriately differ.
