This paper explains that value relevance research assesses how well accounting amounts reflect information used by equity investors, and provides insights into questions of interest to standard setters. A primary focus of financial statements is equity investment. Other uses of financial statement information, such as contracting, do not diminish the importance of value relevance research. Value relevance questions can be addressed using extant valuation models. Value relevance studies address econometric issues that otherwise could limit inferences, and can accommodate and be used to study the implications of accounting conservatism.

This study analyzes the relation between auditors' perceived business risk and audit fees to determine whether audit firms or their clients bear the expected legal costs of business risk. We predict that hourly audit fees and the number of audit hours are increasing in business risk. Using confidential survey data collected by a large international accounting firm for 422 audits, we find that high business risk increases the number of audit hours, but not the fee per hour. This implies that firms perceive firm‐level differences in business risk and obtain compensation through billing additional hours, not by raising the hourly charge.
