SunTrust Banks, Inc. Retirement Plan (the qualified Retirement Plan)
Retirement Plan participants who are Company employees as of December 31, 2007 (Affected Participants) will cease to accrue additional benefits under the existing pension benefit formula after that date and all their accrued benefits will be frozen. Beginning January 1, 2008, Affected Participants who have fewer than 20 years of service and future participants will accrue future pension benefits under a cash balance formula that provides compensation and interest credits to a personal pension account. Affected Participants with 20 or more years of service as of December 31, 2007 will be given the opportunity to choose between continuing a traditional pension benefit accrual under a reduced formula or participating in the new personal pension account. Effective January 1, 2008, the vesting schedule will also change from the current 5-year cliff to a 3-year cliff for participants employed by the Company on and after that date.
