Proprietary Costs and Corporate Lobbying Against Changes in Mandatory Disclosure

The mandated increase in segment disaggregation under SFAS 131 could have harmed shareholders by revealing proprietary information or benefited them by reducing agency problems. Using a sample of firms that lobbied against SFAS 131 on the grounds of competitive harm, I examine whether concerns about proprietary costs, a much-cited reason for nondisclosure, motivate firms to lobby against reporting mandates to protect firms??? competitive position or are used as an excuse to disguise managers??? self-interest. Consistent with the proprietary cost hypothesis, I find that these lobbying firms experienced a decrease in operating performance upon adoption of SFAS 131. I find similar results for nonlobbying firms whose industry associations voiced concern of competitive harm, suggesting that associations are motivated by member concerns to lobby in accounting standard setting. The effect is more pronounced for firms that were forced to increase the number of reportable segments to a greater extent. Moreover, the reduced operating performance arises from lower sales growth and smaller profit margins. These findings shed light on lobbying motives and suggest that concerns about the competitive harm of reporting mandates were warranted.
