Abstract The article focuses on Lea Adams Boykin (LAB) model related to audit risk management. There are three unique features to LAB model. First, they use continuous as well as discrete distributions to define risks for assertions at the transaction level. Second, they apply a computer simulation to "aggregate" the risks at the transaction and balance levels in such a way as to relate to earlier research as well as to auditing standards. Finally, LAB analysis of conditional independence issues represents significant progress in terms of operationalizing the risk models. LAB model uses a "bottom up" strategy in the sense of defining risk by assertion at the transaction level and then using these assessments as building blocks to define risks at the next higher level of aggregation, the balance sheet accounts. Much of the complexity in LAB model arises from the need to assess risks for different amounts of error (tolerable errors, small, medium, large). This complexity can be reduced by focusing on the one overall materiality used for the financial statements as a whole.
