This study provides descriptive evidence on the controversial trend adopted by many firms in recent years of reporting earnings figures on a basis. Pro forma earnings exclude normal income statement items that managers deem to be nonrecurring or nonrepresentative of ongoing operations. We investigate various aspects of pro forma disclosure practice by examining a large sample of actual pro forma press releases issued between January 1998 and December 2000. We find that pro forma announcers tend to be relatively young firms that are concentrated primarily in the tech sector and business services industries. We also find that pro forma firms are significantly less profitable, more liquid, and have higher debt levels, P-E ratios, and book-to-market ratios than other firms in their own industries. Our results indicate that while firms commonly exclude multiple expenses in arriving at their pro forma earnings figure, they usually do not exclude the same items in subsequent pro forma announcements. We further find that pro forma announcers' earnings and sales are generally below market averages during our observation period. Interestingly, we also observe that the frequency of pro forma announcements appears to have exploded precisely when earnings and prices of these firms started to decline. Finally, our data provide evidence consistent with the criticism that pro forma announcements may often be motivated by managers' desires to meet or beat analysts' expectations or to avoid earnings decreases.
