On November 13, 2009, Thermo Fisher Scientific Inc. (the "Company") announced a series of transactions to refinance certain of its outstanding debt. Offering of Senior Notes Pursuant to Rule 144A On November 13, 2009, the Company agreed to sell in a private placement $350,000,000 aggregate principal amount of 2.15% senior notes due 2012 (the "2012 Notes") and $400,000,000 aggregate principal amount of 3.25% senior notes due 2014 (the "2014 Notes" and, together with the 2012 Notes, the "Notes") at an issue price of 99.855% of the principal amount of the 2012 Notes and 99.904% of the principal amount of the 2014 Notes, respectively. The Notes will pay interest on a semi-annual basis. The offering of the Notes is expected to close on November 20, 2009.
The Notes are being sold in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act") and to non-U.S. persons outside the United States pursuant to Regulation S under the Securities Act. In connection with the offering of the Notes, the Company expects to enter into a registration rights agreement pursuant to which it will agree to file a registration statement with respect to an offer to exchange the notes for identical new notes registered under the Securities Act (or, under certain circumstances, a shelf registration statement covering resales of the Notes).
The Company intends to use the net proceeds from the offering of the Notes to refinance certain of its outstanding indebtedness, including the financing of a cash tender offer (the "Offer") by the Company to purchase any and all of its outstanding 2.50% Convertible Senior Notes due 2023 (the "Convertible Notes") and a redemption (the "Redemption") of the Company's 63/4% Senior Subordinated Notes due 2014 (the "Senior Subordinated Notes"), in each case as further discussed below. The Company intends to use any proceeds remaining after the Offer and Redemption for general corporate purposes.
The Notes have not been registered under the Securities Act, and unless so registered, may not be offered or sold in the United States absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and other applicable securities laws.
Copies of the press releases announcing the offering and the pricing of the Notes are attached to this Current Report on Form 8-K as Exhibit 99.1 and 99.2, respectively, and are incorporated herein by reference.
The Company also intends to enter into interest rate swaps with respect to the Notes.
