Taxes and capital structure: evidence from firms' response to the Tax Reform Act of 1986

While the theoretical relation between taxes and capital structurehas been extensively analyzed, the empirical evidence on thisissue has thus far been inconclusive. One of the main difficultiesconfronting previous empirical studies of the cross-sectionalrelationship between taxes and leverage was the control of interveningvariables. The Tax Reform Act of 1986 (TRA), which drasticallychanged the tax regime, provides a unique opportunity to assessthe interaction between taxes and leverage decisions in a controlledenvironment. We test the relationship between leverage and certaintax-related variables for a large sample of companies in theyears surrounding the enactment of the TRA. The results supportthe tax-based theories of capital structure. The findings indicatethat there exists a substitution effect between debt and nondebttax shields, and that both corporate and personal tax ratesaffect leverage decisions.     

Measurement Errors and Information Content of Segment Reporting

This paper assesses the measurement errors inherent in segment reporting. Measurement errors are gauged by comparing the correlation of segment results with their industry to the corresponding correlation for single line-of-business firms operating in the same industry. The findings show that the measurement errors in segment information, particularly earnings, are larger than those in the financial information reported by single line-of-business firms. The cross-sectional variation in the measurement errors can be traced to cost/revenue allocations, management intervention in segment reporting, and the operational structure of multi-segment firms. Market tests indicate that the information content of segment information is inversely related to the estimated measurement errors.

The changing relevance of accounting information to debt holders over time

A number of studies have examined the change over time in the information content of accounting numbers to stockholders. However, the stockholders’ perspective is not necessarily identical to that of debt holders. The two groups face different risks and rewards, and thus their informational needs are not the same. We examine the change in the information content of accounting numbers over time from the debt holders’ perspective and hypothesize about the economic and reporting factors likely to affect this change. Using the association between accounting numbers and bond valuation and returns, we find that the information content to debt holders has increased over time. In contrast, but consistent with prior studies, we find that the information content to equity holders has declined. The results suggest that the increased information content to debt holders is related to changes in credit risk and to reporting factors such as the increase in reporting conservatism, the shift towards fair value accounting, and the increase in the frequency of losses. The findings contribute to the scant literature on the use of accounting information by debt holders and the extent to which financial reporting meets their unique needs.
