Item 1.01Entry into a Material Definitive Agreement.

On May 30, 2014, Tyco International Ltd. (“Tyco”) entered into a Merger Agreement (the “Merger Agreement”) with Tyco International plc, a newly-formed Irish public limited company and subsidiary of Tyco (“Tyco Ireland”). Under the Merger Agreement, and subject to the conditions set forth in the Merger Agreement, Tyco will merge with and into Tyco Ireland, with Tyco Ireland being the surviving company (the “Merger”). The Merger will result in Tyco Ireland becoming Tyco’s publicly-traded parent company and change the jurisdiction of organization of Tyco from Switzerland to Ireland. Tyco shareholders are expected to receive one ordinary share of Tyco Ireland for each common share of Tyco held immediately prior to the effectiveness of the Merger.

Upon completion of the Merger, Tyco Ireland is expected to conduct, through its subsidiaries, the same businesses as conducted by Tyco before the Merger and remain subject to the U.S. Securities and Exchange Commission reporting requirements, the mandates of the Sarbanes-Oxley Act and the Dodd-Frank Wall Street Reform and Consumer Protection Act and the applicable corporate governance rules of the New York Stock Exchange.

The Merger is subject to Tyco shareholder approval of the Merger Agreement and certain other conditions. Tyco plans to ask its shareholders to vote to approve the Merger Agreement at a special general meeting of shareholders.

The foregoing description of the Merger and related transactions does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement filed as Exhibit 2.1 and incorporated herein by reference.
