Rule 101 defines a non-GAAP financial measure as a numerical measure of historical or future performance, financial position, or cash flows that excludes amounts included in the most directly comparable GAAP measure, or includes amounts excluded from it. Operating metrics and ratios built entirely from GAAP figures or from non-financial operating measures do not count, and neither do measures that GAAP, SEC rules, or another applicable regulator requires. Regulation G applies to companies with securities registered under Section 12 or reporting under Section 15(d), excluding registered investment companies.
Under Rule 100, the reconciliation must be quantitative for historical measures and quantitative for forward-looking measures to the extent available without unreasonable efforts. When a measure is disclosed orally, for example on an earnings call or webcast, the requirement can be met by posting the information on the company's website and announcing its location in the same presentation. There are narrow exemptions for certain disclosures by foreign private issuers outside the United States and for communications about business combinations. Rule 102 makes clear that complying with Regulation G does not by itself affect antifraud liability under Rule 10b-5.
Regulation G covers public disclosures generally, including press releases. Item 10(e) of Regulation S-K adds stricter rules when non-GAAP measures appear in an SEC filing, including equal or greater prominence for the GAAP figure, and Item 2.02 of Form 8-K applies part of Item 10(e) to earnings releases. The reconciliation is where an investor sees exactly which costs a company chose to exclude.
