Strategic Progress, TARP Retirement Create Momentum for First Horizon in 2011

MEMPHIS, Tenn., Jan. 21, 2011 (GLOBE NEWSWIRE) -- First Horizon National Corp. (NYSE:FHN) made strategic progress in 2010, showing significantly improved business and credit results, repurchasing its TARP preferred shares and successfully raising capital in the equity and debt markets. In the fourth quarter, positive pre-tax income of $13 million was more than offset by $63 million in costs related to our TARP shares and their retirement, resulting in a diluted loss per share of $0.20. The company recently announced a return to a quarterly cash dividend of $0.01 a share.

"We are excited about our progress in 2010," said Bryan Jordan, First Horizon's CEO. "We reached a number of milestones, and we see momentum building as we enter 2011. We returned to profitability. We retired TARP while keeping our capital position strong. We significantly improved credit quality. We invested in technology that will improve the experience of our customers and employees as well as improve productivity and efficiency. 

"Our priorities for 2011 include growing our business by developing and deepening relationships with our customers, improving our efficiency ratio, effectively deploying capital, continuing to improve credit quality and focusing on the future by remaining nimble and fast in making decisions and responding to our customers' needs and changes in the market."

Financial Results

Strong capital position

Use of non-GAAP measures

Certain measures are included in the text and tables of this release that are non-GAAP, meaning they are not presented in accordance with generally accepted accounting principles (GAAP) in the U.S. FHN's management believes such measures are relevant to understanding the capital position and results of the company. The non-GAAP items presented in this release are tangible common equity to tangible assets, tangible book value per common share, net interest margin computed using net interest income adjusted for FTE, results for core business segments. These measures are reported to FHN's management and board of directors through various internal reports. Additionally, disclosure of the non-GAAP capital ratios provides a meaningful base for comparability to other financial institutions as these ratios have become an important measure of the capital strength of banks as demonstrated by the inclusion in the stress tests administered by the United States Treasury Department under the Capital Assistance Program. Non-GAAP measures are not formally defined by GAAP or codified in the federal banking regulations, and other entities may use calculation methods that differ from those used by FHN. The reconciliation of non-GAAP to GAAP measures and presentation of the most comparable GAAP items is contained in the following table.
