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 Non-GAAP 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.
