If the debentures purchased by KeyCorp Capital I, HNC Statutory Trust II, HNC Statutory Trust III, Willow Grove Statutory Trust I, HNC Statutory Trust IV, Westbank Capital Trust II, or Westbank Capital Trust III are redeemed before they mature, the redemption price will be the principal amount, plus any accrued but unpaid interest.

If the debentures purchased by Harleysville Statutory Trust I are redeemed before they mature, the redemption price will be an annually declining percentage of the principal amount, beginning at 105.10% of the principal amount for a redemption on or after February 22, 2011, and ending at 100% of the principal amount for a redemption on or after February 22, 2021, plus any accrued but unpaid interest. If the debentures purchased by Alliance Capital Trust II are redeemed before they mature, the redemption price will be an annually declining percentage of the principal amount, beginning at 105.438% of the principal amount for a redemption on or after March 8, 2010, and ending at 100% of the principal amount for a redemption on or after March 8, 2020, plus any accrued but unpaid interest. The principal amount of certain debentures includes basis adjustments related to fair value hedges totaling $81 million at September 30, 2016, $68 million at December 31, 2015, and $72 million at September 30, 2015.
