Accounting policies are the rules used by an entity to ensure that transactions are recorded properly and financial statements produced correctly. These policies ensure that accounting activities are handled consistently over time. They are also needed to ensure that an organization follows the applicable accounting framework, such as GAAP or IFRS.
The aggressiveness or conservativeness of a firm's accounting policies provides an indicator of how the management team uses accounting to pursue higher "book" profits. A conservative accounting policy tends to understate the reported financial performance of a business, which makes it easier to report more profits in later periods. The reverse is the case for a set of aggressive accounting policies, which result in more reported profits now and fewer profits later.
Thus, investors should peruse all published policies of an entity to see if the financial statements it produces have the potential to reflect an aggressive view of its results and financial condition.
Accounting policies are included in the notes that accompany the financial statements of a business. In addition, the controller or bookkeeper should list all accounting policies in a standard accounting policies and procedures manual; this is a useful document for training new accountants in how the accounting department operates.
Examples of accounting policies are how a business recognizes revenue, how it recognizes depreciation, which cost flow method is used to recognize inventory, and which research and development costs are capitalized and which are expensed.
