Item 8.01. Other Events.

Since 2011 First Horizon National Corporation, certain affiliated companies, and individual defendants (collectively, “First Horizon”) have defended themselves in a lawsuit with the Federal Housing Finance Agency (“FHFA”), as conservator for the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). The lawsuit concerned the purchase by Fannie Mae and Freddie Mac of certain securities backed by mortgage loans originated by First Horizon prior to its sale of its national mortgage businesses in 2008. On April 29, 2014, in order to avoid the substantial costs and risks of litigation of this matter, First Horizon entered into a settlement agreement with FHFA, Fannie Mae, and Freddie Mac. As a result, First Horizon will pay $110 million to the plaintiffs and the 2011 lawsuit will be dismissed.

First Horizon does not expect to materially adjust its earnings for the first quarter of 2014, which First Horizon previously announced on April 17, 2014. First Horizon had established a reserve for this matter as of March 31, 2014, and insurance was available for a portion of the settlement.

Item 2.02. Results of Operations and Financial Condition.

Item 7.01. Regulation FD Disclosure.

First Horizon’s earnings for the second quarter of 2014 are not expected to be materially impacted in connection with the settlement.

Furnished as Exhibit 99.1 is a copy of First Horizon’s press release, related to the matters discussed above, which is scheduled to be issued April 29, 2014.

The foregoing information and the exhibit are furnished pursuant to Items 2.02 and 7.01. The foregoing information speaks as of the date of this Report, and the exhibit speaks as of its date. First Horizon does not assume any obligation to update said information in the future.
