The relation between non-GAAP earnings and accounting restatements: Evidence after regulation G

Scholarly findings on whether disclosure of Non-GAAP earnings is informative or opportunistic are inconsistent. Since the 2003 implementation of Regulation G, investors can view management's process of adjusting from GAAP earnings to Non-GAAP earnings. This study investigates the information content of Non-GAAP earnings in the context of restatements. The hypotheses of this study are based on the following two propositions. First, the informativeness of Non-GAAP earnings is determined by the nature of items excluded from GAAP earnings to derive Non-GAAP earnings (either nonrecurring special items or recurring exclusions). Second, restatements can be used to distinguish between informative and opportunistic Non-GAAP earnings disclosures. My results show that firms with restatements, especially fraud or core earnings restatements, exhibit greater relative use of NonGAAP earnings disclosures that adjust GAAP earnings for positive other exclusions (recurring expenses). By contrast, disclosures of Non-GAAP earnings derived by excluding nonrecurring expenses (special items) from GAAP earnings are not associated with restatements.
