Item 8.01.  Other Events.

On April 30, 2013, Watts Water Technologies, Inc. (the “Company”) issued a press release announcing that its Board of Directors has authorized the repurchase of up to $90 million of the Company’s Class A Common Stock from time to time on the open market or in privately negotiated transactions. The timing and number of any shares repurchased will be determined by the Company’s management based on its evaluation of market conditions. Repurchases may also be made under a Rule 10b5-1 plan, which would permit shares to be repurchased when the Company might otherwise be precluded from doing so under insider trading laws. The repurchase program may be suspended or discontinued at any time. Any repurchased shares will be available for use in connection with its stock plans and for corporate purposes.

On May 10, 2013, the Company adopted a written trading plan under Rule 10b5-1 of the Securities Exchange Act of 1934, as amended.  The Company implemented this written trading plan in connection with its share repurchase program.  Adopting a trading plan that satisfies the conditions of Rule 10b5-1 allows a company to repurchase its shares at times when it might otherwise be prevented from doing so due to self-imposed trading blackout periods or pursuant to insider trading laws.  A broker selected by the Company will have the authority under the terms and limitations specified in the plan to repurchase shares on the Company’s behalf in accordance with the terms of the plan.

Information regarding share repurchases will be available in the Company’s periodic reports on Form 10-K and 10-Q filed with the Securities and Exchange Commission.
