The initial offering price to investors was 100% of the principal amount thereof. The Unsecured Notes due 2029 bear interest at a rate of 4.75% per annum and will mature on February 15, 2029. On or after February 15, 2024, the Unsecured Notes due 2029 are redeemable, at USF’s option, in whole or in part at a price of 102.375% of the remaining principal, plus accrued and unpaid interest, if any, to the redemption date.
