Item 1.01 Entry into a Material Definitive Agreement.

On November 19, 2013, The ADT Corporation (the “Company”) entered into a Master Confirmation and Supplemental Confirmation (the “ASR Agreement”) with JPMorgan Chase Bank relating to an accelerated share repurchase program (the “ASR Program”). Pursuant to the terms of the ASR Agreement, the Company will repurchase $400 million of its common stock from JPMorgan Chase Bank. The Company will acquire the shares under its previously authorized share repurchase program, which, as announced on November 20, 2013, was increased by $1 billion to a total of $3 billion by the Company’s Board of Directors. The Company will fund the accelerated share repurchase with available cash on hand.

Under the terms of the ASR Agreement, the Company will pay JPMorgan Chase Bank $400 million on November 22, 2013 and on that date will receive initial deliveries of approximately 8 million shares, representing a substantial majority of the shares expected to be retired over the course of the ASR Agreement. The total number of shares ultimately repurchased under the ASR Agreement will be based on the volume-weighted average share price of the Company’s common stock during the calculation period of the ASR Program, less a discount. The accelerated share repurchase is expected to be completed by March 25, 2014, although the completion date may be accelerated at JPMorgan Chase Bank’s option after an initial fixed period. The actual number of shares repurchased will be determined at the completion of the ASR Program.

The ASR Agreement contains the principal terms and provisions governing the ASR Program, including, but not limited to, the mechanism used to determine the number of shares that will be delivered, the required timing of delivery of the shares, the specific circumstances under which JPMorgan Chase Bank is permitted to make adjustments to valuation periods and other economic terms, the specific circumstances under which the ASR Program may be terminated early, and various acknowledgments, representations and warranties made by the Company and JPMorgan Chase Bank to one another. The foregoing description of the ASR Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the ASR Agreement which is filed as Exhibit 10.1 hereto and is incorporated herein by reference.

JPMorgan Chase Bank, N.A. is a lender and acted as Syndication Agent and J.P. Morgan Securities LLC acted as a bookrunner and a lead arranger in the Company’s Five Year Senior Unsecured Revolving Credit Agreement, dated as of June 22, 2012.
