Item 2.05.              Costs Associated with Exit or Disposal Activities.

As of September 27, 2011, Watts Water Technologies, Inc. (the “Company”) notified affected employees in North America that their employment is being terminated under a plan of termination that was previously committed to by management on August 15, 2011.  The plan of termination will result in the reduction of approximately 10% of the Company’s North America non-direct payroll cost.  Employees affected by the plan of termination will be provided with severance payments and outplacement assistance.  The plan of termination is intended to improve the Company’s cost leverage in response to the expected continued slowdown in the Company’s residential and commercial businesses.  Outside of North America, several cost saving actions are also underway and opportunities for additional cost savings are under review.

In connection with the plan of termination in North America, the Company expects to incur total expenses relating to termination benefits of approximately $1.1 million in the third quarter of 2011.  The Company expects to complete substantially all of the activities related to the plan of termination in North America by September 30, 2011.
