Tyco International Announces Total Consideration for Debt Tender Offers

SCHAFFHAUSEN, Switzerland — July 11, 2012 — Tyco International Ltd. (“Tyco”) (NYSE:TYC) today announced the reference yield and the total consideration for each series of notes subject to the previously announced tender offers of Tyco and its subsidiary, Tyco International Finance S.A. (“TIFSA”), to purchase for cash the respective debt securities issued by TIFSA and/or Tyco, as the case may be, listed in the table below, in an aggregate principal amount of up to US$2,600,000,000.

The tender offers consist of two separate offers (each an “Offer”, and collectively, the “Offers”) on the terms set forth in an offer to purchase and related letter of transmittal, each dated June 27, 2012, with (i) an Offer to purchase any and all of specified series of outstanding debt securities (the “Any and All Offer”) and (ii) a second Offer to purchase up to the Maximum Tender Amount (as defined below) of specified series of outstanding debt securities (the “Maximum Tender Offer”).

The total consideration per US$1,000 principal amount of notes validly tendered and accepted for purchase pursuant to the Offers was determined in the manner described in the tender offer documents by reference to a fixed spread specified for the series over the yield based on the bid side price of the U.S. Treasury Security specified in the table below. Holders will also receive accrued and unpaid interest thereon up to, but excluding, the date of payment of the applicable consideration for such notes accepted for purchase in the Any and All Offer or the Maximum Tender Offer, as applicable.

(1)          Tyco is a co-issuer with TIFSA with respect to the 6.000% Notes due 2013, the 7.000% Notes due 2019 and the 6.875% Notes due 2021. Tyco guarantees all the notes listed in the table above except for those notes on which it is co-issuer.

The Any and All Offer will expire at 5:00 p.m. Eastern Daylight Time (EDT) today, July 11, 2012. Holders subject to the Any and All Offer must validly tender and not validly withdraw their notes before 5:00 p.m. EDT today, July 11, 2012 to be eligible to receive the total consideration.

The Maximum Tender Offer is subject to an aggregate purchase limit of US$1,443,903,000 in aggregate principal amount of notes less the aggregate principal amount of notes purchased in the Any and All Offer for the 7.000% Notes due 2019 and in the Any and All Offer for the 8.500% Notes due 2019 (the “Maximum Tender Amount”). The Maximum Tender Offer will expire at 11:59 p.m. EDT on July 25, 2012, unless extended or earlier terminated (such time and date, as the same may be extended, the “Maximum Tender Offer Expiration Date”). Holders subject to the Maximum Tender Offer must validly tender and not validly withdraw their notes before 5:00 p.m. EDT today, July 11, 2012 (such time and date, the “Early Tender Date”) to be eligible to receive the total consideration, which includes an early tender premium of US$30 per US$1,000 principal amount of notes accepted for purchase (the “Early Tender Premium”).

Holders subject to the Maximum Tender Offer who validly tender their notes after the Early Tender Date and before the Maximum Tender Offer Expiration Date will only be eligible to receive an amount equal to the total consideration minus the Early Tender Premium.

The Offers are subject to the satisfaction of certain conditions set forth in the offer to purchase, including, among other things, the consummation of an issuance by The ADT Corporation, Tyco’s wholly-owned subsidiary, of one or more series of notes with terms and conditions and in amount, in each case, satisfactory to Tyco. That condition has now been satisfied.
