Companies are still allowed to present certain figures without abiding by GAAP guidelines, provided that they clearly identify those figures as not conforming to GAAP. Companies sometimes do so when they believe that the GAAP rules are not flexible enough to capture certain nuances about their operations. In that situation, they might provide specially-designed non-GAAP metrics, in addition to the other disclosures required under GAAP. Investors should be skeptical about non-GAAP measures, however, as they can sometimes be used in a misleading manner.
