Non-GAAP Information

Certain measures included in this report are “non-GAAP,” meaning they are not presented in accordance with U.S. GAAP and also are not codified in U.S. banking regulations currently applicable to FHN. Although other entities may use calculation methods that differ from those used by FHN for non-GAAP measures, FHN’s management believes such measures are relevant to understanding the financial condition, capital position, and financial results of FHN and its business segments. Non-GAAP measures are reported to FHN’s management and Board of Directors through various internal reports.

The non-GAAP measures presented in this report arepre-provision net revenue, return on average tangible common equity, tangible common equity to tangible assets, and tangible book value per common share. Table I.2.28 appearing in the MD&A (Item 2 of Part I) of this report provides a reconciliation of non-GAAP items presented in this report to the most comparable GAAP presentation.

Presentation of regulatory measures, even those which are not GAAP, provides a meaningful basis for comparability to other financial institutions subject to the same regulations as FHN, as demonstrated by their use by banking regulators in reviewing capital adequacy of financial institutions. Although not GAAP terms, these regulatory measures are not considered “non-GAAP” under U.S. financial reporting rules as long as their presentation conforms to regulatory standards. Regulatory measures used in this report include: common equity tier 1 capital, generally defined as common equity less goodwill, other intangibles, and certain other required regulatory deductions; tier 1 capital, generally defined as the sum of core capital (including common equity and instruments that cannot be redeemed at the option of the holder) adjusted for certain items under risk based capital regulations; and risk-weighted assets, which is a measure of total on- and off-balance sheet assets adjusted for credit and market risk, used to determine regulatory capital ratios.
