SCHAFFHAUSEN, Switzerland, Sept. 28, 2012 –– Today Tyco (NYSE: TYC), the world’s largest dedicated fire protection and security company, completed its separation transaction.

Tyco is a $10+ billion global leader in fire protection and security solutions. Tyco designs, manufactures, installs and services fire protection and security solutions focused on finding smarter ways to save lives, improve businesses and protect where people live and work.

Tyco’s broad portfolio of products and services allows the company to partner with customers to help them protect people and assets around the world.

In connection with the closing of the spin-off transactions, each Tyco shareholder will receive: (i) one share of common stock of The ADT Corporation for every two shares of Tyco common stock held at the close of business on September 17, 2012 (the record date) and (ii) 0.239943 shares of Pentair Ltd. (formerly known as Tyco Flow Control International Ltd.) (“New Pentair”) common stock for every share of Tyco common stock held at the close of business on the record date. Fractional shares of ADT and/or New Pentair will not be distributed and any Tyco shareholder who would otherwise be entitled to receive a fractional share will instead receive a cash payment. Immediately following the distributions, Pentair, Inc. (“Pentair”) merged with and into a wholly-owned subsidiary of New Pentair.

The distributions have been structured to qualify as tax-free dividends to Tyco shareholders for U.S. federal income tax purposes. Cash received in lieu of fractional shares, however, will be taxable. Shareholders are urged to consult with their tax advisor as to the specific tax consequences of the distributions to them.

Tyco currently has approximately 462 million basic shares outstanding. Based on the distribution ratios noted above, approximately 231 million shares of ADT common stock and 111 million shares of New Pentair common stock will be distributed to Tyco shareholders. As consideration for the merger, shareholders of Pentair will receive one newly issued common share of New Pentair for every Pentair common share that they hold at the time of the merger. After giving effect to the merger, Tyco shareholders as of the record date will own approximately 52.5% of the common shares of Pentair Ltd. on a fully-diluted basis (excluding treasury shares).
