First Horizon National Corporation (FHN)

Retirement Benefits

We provide retirement plan benefits, discussed in this section below, that we believe are customary in our industry. We provide them to remain competitive in retaining talent and seeking new talent to join us.

401(k) Savings Plan

We provide all qualifying full-time employees with the opportunity to participate in our tax-qualified 401(k) savings plan. The plan allows employees to defer receipt of earned salary, up to tax law limits, on a tax-advantaged basis. Accounts may be invested in a wide range of mutual funds and in our common stock. Up to tax law limits, we provide a 50% match for the first 6% of salary each participant with at least one year of service elects to defer into the plan. Matched contributions are initially invested in company stock, but can be re-invested in other available mutual funds at the participant’s election.

Our 401(k) plan was established many years ago. No substantial changes to the match or basic plan structure were made in 2008.

Pension Plan

Our Pension Plan is a traditional broad-based pension plan that provides for a defined benefit to be paid to eligible employees upon retirement. In 2007, the plan was closed and employees hired after August 31, 2007 are not eligible to participate. The benefit is based upon a participant’s average base salary for the highest 60 consecutive months of the last 120 months of service, years of credited service, and social security benefits (under an offset formula). Benefits are normally payable in monthly installments after age 65. Tax laws limit the qualifying salary that can be used, and thus the benefit that can be paid, under the Pension Plan to a dollar amount that is adjusted each year for inflation. The formula works in a traditional manner so that longevity with the company is rewarded.

No substantial changes to the basic plan structure were made in 2008.

Pension Restoration Plan

Our Pension Plan is subject to certain dollar limitations on qualifying compensation and benefits imposed by the tax laws. Our pension restoration plan provides a restorative benefit to all of the executive officers who participate in the Pension Plan, including all of the named executive officers, and other employees approved by the CEO on a case by case basis so that the combined pension and restoration benefit is calculated as if those tax limitations did not exist. The pension and pension restoration plans thus generally operate as a single plan in terms of defining the pension benefit payable to executives. This plan is provided in response to the IRS caps on qualified pension plan benefits.
