First Horizon National Corporation (NYSE:FHN) Files An 8-K Results of Operations and Financial Condition

ITEM 2.02. Results of Operations and Financial Condition.

ITEM 7.01. Regulation FD Disclosure.

Furnished as Exhibit 99.1 is a copy of the First Horizon National
Corporation (FHN) Financial Supplement and Investor Slide
Presentation for the quarter ended March 31, 2017, which was
released today.

The foregoing information is furnished to Item 2.02, Results of
Operations and Financial Condition and Item 7.01, Regulation FD
Disclosure. The exhibit speaks as of the date thereof and FHN
does not assume any obligation to update in the future the
information therein.

Use of Non-GAAP Measures and Regulatory Measures that are
not GAAP in the Exhibit

Certain measures are included in the exhibit that are non-GAAP,
meaning (under U.S. financial reporting rules) they are not
presented in accordance with generally accepted accounting
principles (GAAP) in the U.S. and also are not codified in the
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, FHNs 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 FHNs management and
directors through various internal reports.

Presentation of regulatory measures, some of which follow
regulatory definitions rather than GAAP, provides a meaningful
base for comparability to other financial institutions subject to
the same regulations as FHN. Such measures are used by the
various banking regulators in reviewing the performance,
stability, and capital adequacy of financial institutions they
regulate. 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 the exhibit 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; risk weighted assets (RWA),
which is a measure of total on- and off-balance sheet assets
adjusted for credit and market risk, used to determine regulatory
capital ratios; and pre-provision net revenue (PPNR), calculated
by adding the provision/(provision credit) for loan losses to
income before income taxes.

The non-GAAP measures presented in the exhibit include: return on
average tangible common equity (ROTCE); tangible common equity
(TCE) to tangible assets (TA); tangible book value per common
share; and earnings per share measures reported at the segment
level.

Reconciliations of non-GAAP to GAAP measures and presentation of
the most comparable GAAP items are presented near the end
(immediately before the Glossary) of the Financial Supplement
portion of the exhibit, and at the end of the Investor Slide
Presentation.
