In this Annual Report on Form 10-K, references to "the Company," "Watts," "we," "us" or "our" refer to Watts Water Technologies, Inc. and its consolidated subsidiaries.

Watts Regulator Co. was founded by Joseph E. Watts in 1874 in Lawrence, Massachusetts. Watts Regulator Co. started as a small machine shop supplying parts to the New England textile mills of the 19th century and grew into a global manufacturer of products and systems focused on the control, conservation and quality of water and the comfort and safety of the people using it. Watts Water Technologies, Inc. was incorporated in Delaware in 1985 and became the parent Company of Watts Regulator Co.

Our "Water by Watts" strategy is to be the leading provider of water quality, water conservation, water safety and water flow control products for the residential and commercial markets in North America and Europe with a growing presence in Asia. Our primary objective is to grow earnings by increasing sales within existing markets, expanding into new markets, leveraging our distribution channels and customer base, making selected acquisitions, reducing manufacturing costs and advocating for the development and enforcement of industry standards.

We intend to continue to introduce products in existing markets by enhancing our preferred brands, developing new complementary products, promoting plumbing code development to drive sales of safety and water quality products and continually improving merchandising in both the do-it-yourself (DIY) and wholesale distribution channels. We continually target selected new product and geographic markets based on growth potential, including our ability to leverage our existing distribution channels. Additionally, we continually leverage our distribution channels through the introduction of new products, as well as the integration of products of our acquired companies.

We intend to continue to generate growth by targeting selected acquisitions, both in our core markets as well as new complementary markets. We have completed 32 acquisitions since divesting our industrial and oil and gas business in 1999. Our acquisition strategy focuses on businesses that manufacture preferred brand name products that address our themes of water quality, water conservation, water safety, water flow control and comfort and related complementary markets. We target businesses that will provide us with one or more of the following: an entry into new markets, an increase in shelf space with existing customers, strong brand names, a new or improved technology or an expansion of the breadth of our Water by Watts offerings.

We are committed to reducing our manufacturing and operating costs through a combination of manufacturing in lower-cost countries, using Lean Six Sigma to drive continuous improvement across all key processes, and consolidating our diverse manufacturing operations in North America, Europe and China. We have a number of manufacturing facilities in lower-cost regions such as China, Bulgaria and Tunisia. In both 2007 and 2009, we announced global restructuring plans to reduce our manufacturing footprint in order to reduce our costs and to realize additional operating efficiencies. In February 2010, we announced a plan to consolidate our manufacturing operations in France. See Recent Developments in Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations" for more details.

Our products are sold to wholesale distributors and dealers, major DIY chains and original equipment manufacturers (OEMs). Most of our sales are for products that have been approved under regulatory standards incorporated into state and municipal plumbing, heating, building and fire protection codes in North America and Europe. We have consistently advocated the development and enforcement of plumbing codes and are committed to providing products to meet these standards, particularly for safety and control valve products. These codes serve as a competitive barrier to entry by requiring that products sold in select jurisdictions meet stringent criteria.

Additionally, a majority of our manufacturing facilities are ISO 9000, 9001 or 9002 certified by the International Organization for Standardization.

Our business is reported in three geographic segments: North America, Europe and China. The contributions of each segment to net sales, operating income and the presentation of certain other financial information by segment are reported in Note 17 of the Notes to Consolidated Financial Statements and in "Management's Discussion and Analysis of Financial Condition and Results of Operations" included elsewhere in this report.

In September 2009, our Board of Directors approved the sale of our investment in Watts Valve (Changsha) Co., Ltd. (CWV), located in Changsha, China. We completed the sale of CWV in January 2010. CWV is a manufacturer of large diameter hydraulic-actuated butterfly valves for thermo-power and hydro-power plants, water distribution projects and water works projects in China. Management determined the CWV business no longer fit strategically with the Company.

In May 2009, we commenced proceedings to liquidate our TEAM Precision Pipework, Ltd. (TEAM) business, located in Ammanford, U.K. TEAM custom designed and manufactured manipulated pipe and hose tubing assemblies and served the heating, ventilation and air conditioning and automotive markets in Western Europe. Management determined the business no longer fit strategically with the Company and that a sale of TEAM was not feasible. On May 22, 2009, we appointed an administrator for TEAM under the United Kingdom Insolvency Act of 1986. During the administration process, the administrator has sole control over, and responsibility for, TEAM's operations, assets and liabilities. We deconsolidated TEAM when the administrator obtained control of TEAM. During the third quarter of 2009, we were informed that the administrator completed the sale of TEAM's assets for funds sufficient to pay all creditors. We evaluated the operations of TEAM and determined that it will not have a continuing involvement in TEAM's operations and cash flows. During the fourth quarter, the administrator determined that all TEAM creditors had been contacted and they had agreed to full settlements of the respective debts owed by TEAM. Further, the administrator believes that liquidation of TEAM will result in approximately $0.8 million being returned to us as excess proceeds from liquidation. We recorded this amount in discontinued operations in the fourth quarter. The legal liquidation of TEAM is expected to be finalized by the end of the first quarter of 2010.

Detailed financial information concerning these two disposals is provided in Note 3 of the Notes to Consolidated Financial Statements in this report. All prior years amounts for CWV and TEAM have been reclassified to discontinued operations throughout this document.

We have a broad range of products in terms of design distinction, size and configuration in a majority of our principal product lines. In 2009 and 2008, water quality products accounted for approximately 14% and 17%, respectively, of our total sales. Our principal product lines include:

We sell our products to plumbing, heating and mechanical wholesale distributors, major DIY chains and OEMs.

Wholesalers. Approximately 65% of our sales in both 2009 and 2008 were to wholesale distributors for commercial and residential applications. We rely on commissioned manufacturers' representatives, some of which maintain a consigned inventory of our products, to market our product lines. Additionally, various water quality products are sold to independent dealers throughout North America.

DIY. Approximately 16% and 14% of our sales in 2009 and 2008, respectively, were to DIY customers. Our DIY customers demand less technical products, but are highly receptive to innovative designs and new product ideas.

OEMs. Approximately 19% and 21% of our sales in 2009 and 2008, respectively, were to OEMs. In North America, our typical OEM customers are water heater manufacturers, equipment manufacturers needing flow control devices and water systems manufacturers needing backflow preventers. Our sales to OEMs in Europe are primarily to boiler manufacturers, and radiant systems manufacturers. Our sales to OEMs in China are primarily to boiler and bath manufacturers including manufacturers of faucet and shower products.

In both 2009 and 2008, no customer accounted for more than 10% of our total net sales. Our top ten customers accounted for approximately $306.4 million, or 25%, of our total net sales in 2009 and $302.2 million, or 21%, of our total net sales in 2008. Thousands of other customers constituted the remaining 75% of our net sales in 2009 and 79% of our net sales in 2008.

We rely primarily on commissioned manufacturers' representatives to sell our products, some of which maintain a consigned inventory of our products. These representatives sell primarily to plumbing and heating wholesalers or service DIY store locations in North America. We also sell products for the residential construction and home repair and remodeling industries through DIY plumbing retailers,

national catalog distribution companies, hardware stores, building material outlets and retail home center chains and through plumbing and heating wholesalers. In addition, we sell products directly to certain large OEMs and private label accounts.

We have integrated and automated manufacturing capabilities, including a bronze foundry, machining, plastic extrusion and injection molding and assembly operations. Our foundry operations include metal pouring systems, automatic core making, yellow brass forging and brass and bronze die-castings. Our machining operations feature computer-controlled machine tools, high-speed chucking machines with robotics and automatic screw machines for machining bronze, brass and steel components. We have invested heavily in recent years to expand our manufacturing capabilities and to ensure the availability of the most efficient and productive equipment. We are committed to maintaining our manufacturing equipment at a level consistent with current technology in order to maintain high levels of quality and manufacturing efficiencies.

Capital expenditures and depreciation for each of the last three years were as follows:

We require substantial amounts of raw materials to produce our products, including bronze, brass, cast iron, steel, plastic, and components used in products, and substantially all of the raw materials we require are purchased from outside sources. The commodity markets have experienced tremendous volatility over the past several years, particularly copper. The market prices of many commodities decreased during the latter half of 2008, but increased throughout 2009. Bronze and brass are copper-based alloys. The spot price of copper increased approximately 153.1% from December 31, 2008 to December 31, 2009. We typically carry several months of inventory on-hand primarily due to the significant extent of our international sourcing. We are not able to predict whether commodity costs, including copper, will significantly increase or decrease in the future. If commodity costs increase in the future and we are not able to reduce or eliminate the effect of the cost increases by reducing production costs or implementing price increases, our profit margins could decrease. If commodity costs were to decline, we may experience pressures from customers to reduce our selling prices. The timing of any price reductions and decreases in commodity costs may not align. As a result, our near-term margins in 2010 could decline.

With limited exceptions, we do not single source our commodities or other raw materials. Generally we have multiple suppliers for our commodities and other raw materials. We believe our relationships with our key suppliers are good and that an interruption in supply from any supplier would not materially affect our ability to meet our immediate demands while another supplier is qualified. We regularly review our suppliers to evaluate their strengths. If a supplier is evaluated as having potential financial troubles or will be unable to meet our demands, we believe that our inventory of raw materials will allow for sufficient time to identify and obtain the necessary commodities and other raw materials from an alternate source. We believe that the nature of our commodities or other raw materials are such that multiple sources are generally available in the market.

Products representing a majority of our sales are subject to regulatory standards and code enforcement which typically require that these products meet stringent performance criteria. Standards are established by such industry test and certification organizations as the American Society of Mechanical Engineers (A.S.M.E.), the Canadian Standards Association (C.S.A.), the American Society of Sanitary Engineers (A.S.S.E.), the University of Southern California Foundation for Cross-Connection Control (USC FCC), the International Association of Plumbing and Mechanical Officials (I.A.P.M.O.), Factory Mutual (F.M.), the National Sanitation Foundation (N.S.F.) and Underwriters Laboratory (U.L.). Many of these standards are incorporated into state and municipal plumbing and heating, building and fire protection codes.

National regulatory standards in Europe vary by country. The major standards and/or guidelines that our products must meet are AFNOR (France), DVGW (Germany), UNI/ICIN (Italy), KIWA (Netherlands), SVGW (Switzerland), SITAC (Sweden) and WRAS (United Kingdom). Further, there are local regulatory standards requiring compliance as well.

Together with our commissioned manufacturers' representatives, we have consistently advocated for the development and enforcement of plumbing codes. We maintain stringent quality control and testing procedures at each of our manufacturing facilities in order to manufacture products in compliance with code requirements.

We believe that product-testing capability and investment in plant and equipment is needed to manufacture products in compliance with code requirements. Additionally, a majority of our manufacturing facilities are ISO 9000, 9001 or 9002 certified by the International Organization for Standardization.

We maintain our own product development staff, design teams, and testing laboratories in North America, Europe and China that work to enhance our existing products and develop new products. We maintain sophisticated product development and testing laboratories. Research and development costs included in selling, general, and administrative expense amounted to $17.8 million, $17.5 million and $15.1 million for the years ended December 31, 2009, 2008 and 2007, respectively.

On January 1, 2010, California and Vermont enacted laws that require all pipes, pipe and plumbing fittings and plumbing fixtures sold in those states that convey or dispense water for human consumption to contain virtually no lead content. Other states are currently considering similar legislation and we expect that similar laws may be adopted in other states in the future. We have invested considerable resources over the past several years to develop lead free versions of our plumbing products to comply with these new laws, and we introduced our lead free product offerings in the fourth quarter of 2009.

The domestic and international markets for water safety and flow control devices are intensely competitive and require us to compete against some companies possessing greater financial, marketing and other resources than ours. Due to the breadth of our product offerings, the number and identities of our competitors vary by product line and market. We consider brand preference, engineering specifications, plumbing code requirements, price, technological expertise, delivery times and breadth of product offerings to be the primary competitive factors. We believe that new product development and product engineering are also important to success in the water industry and that our position in the industry is attributable in part to our ability to develop new and innovative products quickly and to adapt and enhance existing products. We continue to develop new and innovative products to enhance market position and are continuing to implement manufacturing and design programs to reduce costs. We cannot be certain that our efforts to develop new products will be successful or that our customers

will accept our new products. Although we own certain patents and trademarks that we consider to be of importance, we do not believe that our business and competitiveness as a whole are dependent on any one of our patents or trademarks or on patent or trademark protection generally.

Backlog was approximately $86.6 million at February 12, 2010 and was approximately $77.6 million at February 13, 2009. We do not believe that our backlog at any point in time is indicative of future operating results and we expect our entire current backlog to be converted to sales in 2010.

As of December 31, 2009, our wholly-owned domestic and foreign operations employed approximately 5,900 people. None of our employees in North America or China are covered by collective bargaining agreements. In some European countries our employees are subject to traditional national collective bargaining agreements. We believe that our employee relations are good.

We are subject to a variety of potential liabilities connected with our business operations, including potential liabilities and expenses associated with possible product defects or failures and compliance with environmental laws. We maintain product liability and other insurance coverage, which we believe to be generally in accordance with industry practices. Nonetheless, such insurance coverage may not be adequate to protect us fully against substantial damage claims.

As has been previously disclosed, we were party to a lawsuit filed by Nora Armenta in California Superior Court against us, James Jones Company, Mueller Co. and Tyco International (the "Armenta case") and a separate lawsuit filed in California Superior Court on behalf of the City of Banning, California and 42 other cities and water districts in California against us, James Jones Company and Mueller Co. (the "City of Banning case"). At a mediation session held with the California Superior Court on June 9-10, 2009, the parties to the Armenta case and the City of Banning case agreed in principle to settle both cases. The agreement in principle was effective and binding only upon approval by the plaintiffs in the Armenta and City of Banning cases, and final approval of the settlement by the California Superior Court after a fairness hearing. An agreement in principle also was reached to settle the related insurance coverage cases Watts Industries, Inc. vs. Zurich American Insurance Company, et al., and Zurich American Insurance Company vs. Watts Industries, Inc., et al., pending in California Superior Court; and Zurich American Insurance Company vs. Watts Industries, Inc. and James Jones Company, pending in the United States District Court for the Northern District of Illinois, Eastern Division. The settlement of the insurance coverage cases was effective and binding upon approval of the settlement of the underlying Armenta case and City of Banning case as described above.

The settlement agreement was approved by the plaintiffs in both the Armenta and City of Banning cases and, at the fairness hearing held on November 5, 2009, the California Superior Court approved the settlement of the Armenta case and City of Banning case. There were no objectors to the settlement. Based on the contemporaneous final settlement of the underlying insurance coverage cases, our contribution to the settlement was $15.3 million. As a result of the settlements, all lawsuits and all claims were dismissed. In addition, separate from the settlement, we paid our outside counsel an additional $5.0 million for services rendered in connection with the above described litigation.

As a result of the settlement of the above described litigation, we recorded a non-cash, pre-tax gain in discontinued operations of approximately $9.5 million in the fourth quarter of 2009 to reduce previously recorded estimates of the loss and related fees to the amounts noted above.

In July 2009, we received information that employees of CWV, at that time an indirect wholly-owned subsidiary of the Company in China, made payments to employees of state-owned agencies. Such payments may violate the Foreign Corrupt Practices Act. We are conducting an investigation utilizing outside counsel and voluntarily disclosed this matter to the United States Department of Justice and the Securities and Exchange Commission. We cannot predict the outcome of this matter at this time or whether it will have a materially adverse impact on our financial condition or results of operations. We sold CWV in January 2010.

We have been named as a potentially responsible party with respect to a limited number of identified contaminated sites. The levels of contamination vary significantly from site to site as do the related levels of remediation efforts. Environmental liabilities are recorded based on the most probable cost, if known, or on the estimated minimum cost of remediation. We accrue estimated environmental liabilities based on assumptions, which are subject to a number of factors and uncertainties.

Circumstances which can affect the reliability and precision of these estimates include identification of additional sites, environmental regulations, level of cleanup required, technologies available, number and financial condition of other contributors to remediation and the time period over which remediation may occur. We recognize changes in estimates as new remediation requirements are defined or as new information becomes available.

Based on the facts currently known to us, we do not believe that the ultimate outcome of these matters will have a material adverse effect on our liquidity, financial condition or results of operations. Some of our environmental matters are inherently uncertain and there exists a possibility that we may ultimately incur losses from these matters in excess of the amount accrued. However, we cannot currently estimate the amount of any such additional losses.

We are defending approximately 105 lawsuits in different jurisdictions, with the greatest number filed in Mississippi and California state courts, alleging injury or death as a result of exposure to asbestos. The complaints in these cases typically name a large number of defendants and do not identify any particular Watts products as a source of asbestos exposure. To date, we have obtained a dismissal in every case before it has reached trial because discovery has failed to yield evidence of substantial exposure to any Watts products. Based on the facts currently known to us, we do not believe that the ultimate outcome of these claims will have a material adverse effect on our liquidity, financial condition or results of operations.

Other lawsuits and proceedings or claims, arising from the ordinary course of operations, are also pending or threatened against us. Based on the facts currently known to us, we do not believe that the ultimate outcome of these other litigation matters will have a material adverse effect on our liquidity, financial condition or results of operations.

Current economic cycles, particularly reduced levels of commercial and residential starts and remodeling, may continue to have an adverse effect on our revenues and operating results.

We have experienced and expect to continue to experience fluctuations in revenues and operating results due to economic and business cycles. The businesses of most of our customers, particularly plumbing and heating wholesalers and home improvement retailers, are cyclical. Therefore, the level of our business activity has been cyclical, fluctuating with economic cycles. The current economic downturn may also affect the financial stability of our customers, which could affect their ability to pay amounts owed vendors, including us. We also believe our level of business activity is influenced by commercial and residential starts and renovation and remodeling, which are, in turn, heavily influenced by interest rates, consumer debt levels, changes in disposable income, employment growth and consumer confidence. The current credit market conditions may prevent commercial and residential builders or developers from obtaining the necessary capital to continue existing projects or to start new projects. This may result in the delay or cancellation of orders from our customers or potential customers and may adversely affect our revenues and our ability to manage inventory levels, collect customer receivables and maintain profitability. The current conditions in the housing and debt markets have caused a significant reduction in commercial and residential starts and renovation and remodeling. These conditions have caused a decrease in our revenue and profit. If these conditions continue or worsen in the future, our revenues and profits could decrease and could result in a material adverse effect on our financial condition and results of operations.

Our ability to make large acquisitions may be limited due to the current credit market conditions.

As widely reported, the financial markets worldwide have been experiencing, among other things, severely diminished liquidity and credit availability. One of our strategies is to increase our revenues

and profitability and expand our business through acquisitions. We may require capital in excess of our available cash and the unused portion of our revolving credit facility to make large acquisitions, which we would generally obtain from access to the credit markets. However, the current economic environment may adversely affect the availability and cost of credit in the future. There can be no assurance that if a large acquisition is identified that we would have access to sufficient capital to complete such acquisition.

We face intense competition and, if we are not able to respond to competition in our markets, our revenues may decrease.

Competitive pressures in our markets could adversely affect our competitive position, leading to a possible loss of market share or a decrease in prices, either of which could result in decreased revenues and profits. We encounter intense competition in all areas of our business. Additionally, we believe our customers are attempting to reduce the number of vendors from which they purchase in order to reduce the size and diversity of their inventories and their transaction costs. To remain competitive, we will need to invest continually in manufacturing, marketing, customer service and support and our distribution networks. We may not have sufficient resources to continue to make such investments and we may be unable to maintain our competitive position. In addition, we anticipate that we may have to reduce the prices of some of our products to stay competitive, potentially resulting in a reduction in the profit margin for, and inventory valuation of, these products. Some of our competitors are based in foreign countries and have cost structures and prices in foreign currencies. Accordingly, currency fluctuations could cause our U.S. dollar-priced products to be less competitive than our competitors' products which are priced in other currencies.

Changes in the costs of raw materials could reduce our profit margins. Reductions or interruptions in the supply of components or finished goods from international sources could adversely affect our ability to meet our customer delivery commitments.

We require substantial amounts of raw materials, including bronze, brass, cast iron, steel and plastic and substantially all of the raw materials we require are purchased from outside sources. The costs of raw materials may be subject to change due to, among other things, interruptions in production by suppliers and changes in exchange rates and worldwide price and demand levels. We typically do not enter into long-term supply agreements. Our inability to obtain supplies of raw materials for our products at favorable costs could have a material adverse effect on our business, financial condition or results of operations by decreasing our profit margins. The commodity markets have experienced tremendous volatility over the past several years, particularly copper. The market prices of many commodities decreased during the latter half of 2008, but increased significantly during 2009 and into February 2010. Should commodity costs continue to increase substantially, we may not be able to completely recover such costs, through selling price increases to our customers or other product cost reductions, which would have a negative effect on our financial results. Additionally, we continue to purchase increased levels of components and finished goods from international sources. In limited cases, these components or finished goods are single-sourced. The availability of components and finished goods from international sources could be adversely impacted by, among other things, interruptions in production by suppliers, suppliers' allocations to other purchasers and new laws or regulations. This could impact our ability to deliver products to our customers on a timely basis.

Implementation of our acquisition strategy may not be successful, which could affect our ability to increase our revenues or our profitability.

One of our strategies is to increase our revenues and profitability and expand our business through acquisitions that will provide us with complementary water-related products and increase market share for our existing product lines. We cannot be certain that we will be able to identify, acquire or profitably manage additional companies or successfully integrate such additional companies without substantial costs, delays or other problems. Also, companies acquired recently and in the future may not achieve revenues, profitability or cash flows that justify our investment in them. In 2009, we

recorded losses associated with the fairly recent CWV and TEAM acquisitions, resulting from their pending disposal and liquidation, respectively. We expect to spend significant time and effort in expanding our existing businesses and identifying, completing and integrating acquisitions. We have faced increasing competition for acquisition candidates which have resulted in significant increases in the purchase prices of many acquisition candidates. This competition, and the resulting purchase price increases, may limit the number of acquisition opportunities available to us, possibly leading to a decrease in the rate of growth of our revenues and profitability. In addition, acquisitions may involve a number of risks, including, but not limited to:

We are subject to risks related to product defects, which could result in product recalls and could subject us to warranty claims in excess of our warranty provisions or which are greater than anticipated due to the unenforceability of liability limitations.

We maintain strict quality controls and procedures, including the testing of raw materials and safety testing of selected finished products. However, we cannot be certain that our testing will reveal latent defects in our products or the materials from which they are made, which may not become apparent until after the products have been sold into the market. We also cannot be certain that our suppliers will always eliminate latent defects in products we purchase from them. Accordingly, there is a risk that product defects will occur, which could require a product recall. Product recalls can be expensive to implement and, if a product recall occurs during the product's warranty period, we may be required to replace the defective product. In addition, a product recall may damage our relationship with our customers and we may lose market share with our customers. Our insurance policies may not cover the costs of a product recall.

Our standard warranties contain limits on damages and exclusions of liability for consequential damages and for misuse, improper installation, alteration, accident or mishandling while in the possession of someone other than us. We may incur additional operating expenses if our warranty provision does not reflect the actual cost of resolving issues related to defects in our products. If these additional expenses are significant, it could adversely affect our business, financial condition and results of operations.

We face risks from product liability and other lawsuits, which may adversely affect our business.

We have been and expect to continue to be subject to various product liability claims or other lawsuits, including, among others, that our products include inadequate or improper instructions for use or installation, or inadequate warnings concerning the effects of the failure of our products. In the event that we do not have adequate insurance or contractual indemnification, damages from these claims would have to be paid from our assets and could have a material adverse effect on our results of operations, liquidity and financial condition. We, like other manufacturers and distributors of products designed to control and regulate fluids and gases, face an inherent risk of exposure to product liability claims and other lawsuits in the event that the use of our products results in personal injury, property damage or business interruption to our customers. Although we maintain strict quality controls and procedures, including the testing of raw materials and safety testing of selected finished products, we cannot be certain that our products will be completely free from defect. In addition, in certain cases,

we rely on third-party manufacturers for our products or components of our products. Although we have product liability and general insurance coverage, we cannot be certain that this insurance coverage will continue to be available to us at a reasonable cost, or, if available, will be adequate to cover any such liabilities. For more information, see "Item 1. Business—Product Liability, Environmental and Other Litigation Matters."

Economic and other risks associated with international sales and operations could adversely affect our business and future operating results.

Since we sell and manufacture our products worldwide, our business is subject to risks associated with doing business internationally. Our business and future operating results could be harmed by a variety of factors, including:

Fluctuations in foreign exchange rates could materially affect our reported results.

We are exposed to fluctuations in foreign currencies, as a portion of our sales and certain portions of our costs, assets and liabilities are denominated in currencies other than U.S. dollars. Approximately 45.1% of our sales during the year ended December 31, 2009 were from sales outside of the U.S. compared to 44.2% for the year ended December 31, 2008. For the year ended December 31, 2009, the depreciation of the euro against the U.S. dollar had a negative impact on sales of approximately $17.7 million compared to the year ended December 31, 2008. In 2008, the appreciation of the euro against the U.S. dollar had a positive impact on sales of approximately $30.2 million compared to 2007. There were also minor impacts on sales in other European currencies such as the pound sterling and Danish krone against the U.S. dollar. Additionally, our Canadian operations require significant amounts of U.S. purchases for their operations. Instead of buying or manufacturing domestically, we currently have a favorable cost structure for certain goods we source from our wholly-owned subsidiaries in China and our outside vendors. Although the value of the yuan was unchanged at 6.8 from December 31, 2008 to December 31, 2009, history has shown that when the currency does float, changes of up to 15% have occurred. Although there are currently no indicators that the yuan will appreciate or depreciate in the near term, any decision by the Chinese government to manage their currency in a different manner could result in additional volatility to the Company. The spot rate of the euro and Canadian dollar increased in value as of December 31, 2008 to December 31, 2009 by approximately 3% and 16%, respectively, against the U.S. dollar, while the yuan remained flat. If our share of revenue and purchases in non-dollar denominated currencies continues to increase in future periods, exchange rate fluctuations may have a greater impact on our results of operations and financial condition.

Our ability to achieve savings through our restructuring plans may be adversely affected by local regulations or factors beyond the control of management.

We implemented restructuring plans in 2007 and in 2009 and announced a new restructuring plan for France in 2010. Management's plans include a number of steps that we believe are necessary to reduce operating costs and increase efficiencies throughout our manufacturing, sales and distribution footprint. Although we have considered the impact of local regulations, negotiations with employee representatives, the timing of capital expenditures necessary to prepare facilities and the related costs associated with these activities, factors beyond the control of management may affect the timing and therefore affect when the savings will be achieved under the plans. Further, if we are not successful in completing the restructuring projects in the time frames contemplated or if additional issues arise during the projects that add costs or disrupt customer service, then our operating results could be negatively affected.

The requirements to evaluate goodwill and non-amortizable assets for impairment may result in a write-off of all or a portion of our recorded amounts, which would negatively affect our operating results and financial condition.

As of December 31, 2009, we recorded goodwill and non-amortizable intangible assets of $425.1 million and $51.2 million, respectively. In lieu of amortization, we are required to perform an annual impairment review of both goodwill and non-amortizable intangible assets. In performing our annual review in 2009, we recognized a non-cash pre-tax charge of approximately $3.3 million as an impairment of some of the indefinite lived intangible assets. In performing our annual goodwill review in 2008, we recognized a non-cash pre-tax charge of approximately $22.0 million as an impairment of all the goodwill value related to one reporting unit. Although we have not experienced goodwill impairment in our remaining reporting units, there can be no assurances that future goodwill impairment will not occur. We perform our annual test for indications of goodwill and non-amortizable intangible assets impairment in the fourth quarter of our fiscal year or sooner if indicators of impairment exist.

The loss or financial instability of a major customer could have an adverse effect on our results of operations.

In 2009, our top ten customers accounted for approximately 25% of our total net sales with no one customer accounting for more than approximately 6% of our total net sales. Our customers generally are not obligated to purchase any minimum volume of products from us and are able to terminate their relationships with us at any time. In addition, increases in the prices of our products could result in a reduction in orders for our customers. A significant reduction in orders from, or change in terms of contracts with, any significant customers could have a material adverse effect on our future results of operations. Furthermore, some of our major customers are facing financial challenges due to market declines and heavy debt levels; should these challenges become acute, our results could be materially adversely affected due to reduced orders and/or payment delays or defaults.

Certain indebtedness may limit our ability to pay dividends, incur additional debt and make acquisitions and other investments.

Our revolving credit facility and other senior indebtedness contain operational and financial covenants that restrict our ability to make distributions to stockholders, incur additional debt and make acquisitions and other investments unless we satisfy certain financial tests and comply with various financial ratios. If we do not maintain compliance with these covenants, our creditors could declare a default under our revolving credit facility or senior notes and our indebtedness could be declared immediately due and payable. Our ability to comply with the provisions of our indebtedness may be affected by changes in economic or business conditions beyond our control. Further, given the current condition of the credit markets, should we require additional debt financing above our existing credit limit, we cannot be assured such financing would be available to us or available to us on reasonable economic terms.

We are investigating potential violations of the Foreign Corrupt Practices Act, and the results of this investigation could have a material adverse effect on our business prospects, operations, financial condition and cash flow.

As previously disclosed, we have received information that employees of a former subsidiary of the Company in China made payments to employees of state-owned agencies. Such payments may violate the Foreign Corrupt Practices Act, or FCPA. We are conducting an investigation utilizing outside counsel and voluntarily disclosed this matter to the United States Department of Justice and the Securities and Exchange Commission. If violations are found, we may be subject to criminal and/or civil sanctions, including substantial fines. Negotiated dispositions of these types of violations also often result in an acknowledgement of wrongdoing by the entity and the appointment of a monitor on terms agreed upon with the Department of Justice and the Securities and Exchange Commission to review and monitor current and future business practices with the goal of assuring future FCPA compliance. The amount of any fines or monetary penalties which could be assessed would depend on, among other factors, findings regarding the amount, timing, nature and scope of any improper payments, whether any such payments were authorized by or made with knowledge of Watts or its affiliates, the amount of gross pecuniary gain or loss involved, and the level of cooperation provided to the government authorities during the investigation. Any determination that we have violated the FCPA could result in sanctions that could have a material adverse effect on our business prospects, operations, financial condition and cash flow.

One of our stockholders can exercise substantial influence over our Company.

Our Class B Common Stock entitles its holders to ten votes for each share and our Class A Common Stock entitles its holders to one vote per share. As of February 1, 2010, Timothy P. Horne, a member of our board of directors, beneficially owned approximately 19.5% of our outstanding shares of Class A Common Stock (assuming conversion of all shares of Class B Common Stock beneficially owned by Mr. Horne into Class A Common Stock) and approximately 99.0% of our outstanding shares of Class B Common Stock, which represents approximately 70.2% of the total outstanding voting power. As long as Mr. Horne controls shares representing at least a majority of the total voting power of our outstanding stock, Mr. Horne will be able to unilaterally determine the outcome of most stockholder votes, and other stockholders will not be able to affect the outcome of any such votes.

Conversion and sale of a significant number of shares of our Class B Common Stock could adversely affect the market price of our Class A Common Stock.

As of February 1, 2010, there were outstanding 29,505,918 shares of our Class A Common Stock and 7,193,880 shares of our Class B Common Stock. Shares of our Class B Common Stock may be converted into Class A Common Stock at any time on a one for one basis. Under the terms of a registration rights agreement with respect to outstanding shares of our Class B Common Stock, the holders of our Class B Common Stock have rights with respect to the registration of the underlying Class A Common Stock. Under these registration rights, the holders of Class B Common Stock may require, on up to two occasions, that we register their shares for public resale. If we are eligible to use Form S-3 or a similar short-form registration statement, the holders of Class B Common Stock may require that we register their shares for public resale up to two times per year. If we elect to register any shares of Class A Common Stock for any public offering, the holders of Class B Common Stock are entitled to include shares of Class A Common Stock into which such shares of Class B Common Stock may be converted in such registration. However, we may reduce the number of shares proposed to be registered in view of market conditions. We will pay all expenses in connection with any registration, other than underwriting discounts and commissions. If all of the available registered shares are sold into the public market the trading price of our Class A Common Stock could decline.

As of December 31, 2009, we maintained approximately 70 facilities worldwide, including our corporate headquarters located in North Andover, Massachusetts. The remaining facilities consist of foundries, manufacturing facilities, warehouses, sales offices and distribution centers. The principal properties in each of our three geographic segments and their location, principal use and ownership status are set forth below:

Certain of our facilities are subject to mortgages and collateral assignments under loan agreements with long-term lenders. In general, we believe that our properties, including machinery, tools and equipment, are in good condition, well maintained and adequate and suitable for their intended uses. Many of our manufacturing plants are currently operating at levels that our management considers below normal capacity due to the current worldwide recession. As part of our continuous manufacturing footprint review, management plans to further consolidate its operations. See Recent Developments in Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations," for more details.

We are from time to time involved in various legal and administrative procedures. See Item 1. "Business—Product Liability, Environmental and Other Litigation Matters," which is incorporated herein by reference.

Item 5. MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES.

The following table sets forth the high and low sales prices of our Class A Common Stock on the New York Stock Exchange during 2009 and 2008 and cash dividends paid per share.

There is no established public trading market for our Class B Common Stock, which is held by members of the Horne family. The principal holders of such stock are subject to restrictions on transfer with respect to their shares. Each share of our Class B Common Stock (10 votes per share) is convertible into one share of Class A Common Stock (1 vote per share).

On February 9, 2010, we declared a quarterly dividend of eleven cents ($0.11) per share on each outstanding share of Class A Common Stock and Class B Common Stock.

Aggregate common stock dividend payments in both 2009 and 2008 were $16.2 million, which consisted of $13.0 million and $3.2 million for Class A shares and Class B shares, respectively. While we presently intend to continue to pay cash dividends, the payment of future cash dividends depends upon the Board of Directors' assessment of our earnings, financial condition, capital requirements and other factors.

The number of record holders of our Class A Common Stock as of February 19, 2010 was 156. The number of record holders of our Class B Common Stock as of February 19, 2010 was 7.

We satisfy the minimum withholding tax obligation due upon the vesting of shares of restricted stock and the conversion of restricted stock units into shares of Class A Common Stock by automatically withholding from the shares being issued a number of shares with an aggregate fair market value on the date of such vesting or conversion that would satisfy the withholding amount due.

We did not withhold any Class A Common Stock for withholding tax obligations during the quarter ended December 31, 2009.

The following table includes information with respect to repurchases we made of our Class A Common Stock during the quarter ended December 31, 2009.

Set forth below is a line graph comparing the cumulative total shareholder return on our Class A Common Stock for the last five years with the cumulative return of companies on the Standard & Poor's 500 Stock Index and the Russell 2000 Index. We chose the Russell 2000 Index because it represents companies with a market capitalization similar to that of Watts. The graph assumes that the value of the investment in our Class A Common Stock and each index was $100 at December 31, 2004 and that all dividends were reinvested.

Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

We are a leading supplier of products for use in the water quality, water safety, water flow control and water conservation markets in both North America and Europe with a presence in Asia. For over 135 years, we have designed and manufactured products that promote the comfort and safety of people and the quality and conservation of water used in commercial and residential applications. We earn revenue and income almost exclusively from the sale of our products. Our principal product lines include:

Our business is reported in three geographic segments: North America, Europe and China. We distribute our products through three primary distribution channels: wholesale, do-it-yourself (DIY) and original equipment manufacturers (OEMs). Interest rates have an indirect effect on the demand for our products due to the effect such rates have on the number of new residential and commercial construction starts and remodeling projects. All three of these activities have an impact on our sales and earnings. An additional factor that has had an effect on our sales is fluctuation in foreign currencies, as a portion of our sales and certain portions of our costs, assets and liabilities are denominated in currencies other than the U.S. dollar.

We believe that the factors relating to our future growth include our ability to continue to make selective acquisitions, both in our core markets as well as in new complementary markets, regulatory requirements relating to the quality and conservation of water, increased demand for clean water, continued enforcement of plumbing and building codes and a healthy economic environment. We have completed 32 acquisitions since divesting our industrial and oil and gas business in 1999. Our acquisition strategy focuses on businesses that manufacture preferred brand name products that address our themes of water quality, water conservation, water safety and water flow control and related complementary markets. We target businesses that will provide us with one or more of the following: an entry into new markets, an increase in shelf space with existing customers, a new or improved technology or an expansion of the breadth of our water quality, water conservation, water safety and water flow control products for the residential and commercial markets.

Products representing a majority of our sales are subject to regulatory standards and code enforcement, which typically require that these products meet stringent performance criteria. Together with our commissioned manufacturers' representatives, we have consistently advocated for the development and enforcement of such plumbing codes. We are focused on maintaining stringent quality control and testing procedures at each of our manufacturing facilities in order to manufacture products

in compliance with code requirements and take advantage of the resulting demand for compliant products. We believe that the product development, product testing capability and investment in plant and equipment needed to manufacture products in compliance with code requirements, represent a barrier to entry for competitors. We believe that, over the long term, there is an increasing demand among consumers for products to ensure water quality, which creates growth opportunities for our products.

Our sales in 2009 were affected by downward pressure from a weak U.S. commercial construction marketplace. In addition, U.S. residential construction activity was at historically low levels. We continued to see marked reductions in European sales as the European economy migrated into a recession. Plant under-absorption and negative foreign currency movements affected operating results in 2009. Foreign currency movements, mainly related to the strengthening of the U.S. dollar against the euro and Canadian dollar, negatively affected 2009 diluted earnings per share by $0.03 compared to 2008. In response to these concerns, we took numerous steps to ensure we remain on a firm fiscal platform. In the latter half of 2008, we announced a reduction of the United States workforce, implemented a ten-month salary freeze in North America and initiated a review of discretionary spending in order to reduce operating expenses. In 2009, we expanded our cost savings programs on a worldwide basis. We initiated salary reductions, worker furloughs and other cost reductions in an effort to leverage our costs against anticipated lower sales volumes. Additionally, in February 2009, we expanded and accelerated our restructuring program to consolidate our manufacturing footprint in North America and China. Savings from this program will be realized in 2010. Lastly, we are continuing our implementation of lean manufacturing and Six Sigma disciplines to partially offset negative pressures on operating income.

We require substantial amounts of raw materials to produce our products, including bronze, brass, cast iron, steel, plastic and components used in products, and substantially all of the raw materials we require are purchased from outside sources. We have experienced volatility in the costs of certain raw materials, particularly copper. Bronze and brass are copper-based alloys. The spot price of copper during 2009 increased approximately 153.1% from December 31, 2008. We typically carry several months of inventory on-hand primarily due to the significant extent of our international sourcing.

A risk we face is our ability to deal effectively with changes in raw material costs. We manage this risk by monitoring related market prices, working with our suppliers to achieve the maximum level of stability in their costs and related pricing, seeking alternative supply sources when necessary, implementing cost reduction programs and passing increases in costs to our customers. Additionally from time to time we may use commodity futures contracts on a limited basis to manage this risk. We are not able to predict whether or for how long this volatility will continue.

Another risk we face in all areas of our business is competition. We consider brand preference, engineering specifications, code requirements, price, technological expertise, delivery times and breadth of product offerings to be the primary competitive factors. As mentioned previously, we believe that the product development, product testing capability and investment in plant and equipment needed to manufacture products in compliance with code requirements, represent a barrier to entry for competitors. We are committed to maintaining our capital equipment at a level consistent with current technologies, and thus we spent approximately $24.2 million in 2009 and $26.2 million in 2008.

In September 2009, our Board of Directors approved the sale of our investment in Watts Valve (Changsha) Co., Ltd. (CWV). We completed the sale of CWV in January 2010. Additionally, in May 2009, we liquidated our TEAM Precision Pipework, Ltd. (TEAM) subsidiary through an administration process under the United Kingdom law, as more fully described in Note 3 of Notes to Consolidated Financial Statements. We classified CWV and TEAM's results of operations and any related losses as discontinued operations for all periods presented.

On February 9, 2010, we declared a quarterly dividend of eleven cents ($0.11) per share on each outstanding share of Class A Common Stock and Class B Common Stock.

On February 8, 2010, our Board of Directors approved a restructuring program with respect to our operating facilities in France. The restructuring program is expected to include the shutdown of three facilities, including two manufacturing sites and one distribution center. The program is expected to include pre-tax charges totaling approximately $12.5 million, including costs for severance, relocation, clean-up and certain asset write-downs, and result in the elimination of approximately 95 positions. Total net after-tax charges for this restructuring program are expected to be approximately $8.3 million ($1.1 million in non-cash charges), with costs being incurred through 2011. We expect to spend approximately $6.6 million in capital expenditures to consolidate operations. Annual cash savings, net of tax, are estimated to be $3.9 million, which we expect to fully realize by 2012. We recorded after-tax charges of approximately $3.0 million, or ($0.08) per share, in the fourth quarter of 2009 for severance and other costs related to this program.

On February 8, 2010, Daniel J. Murphy, III, one of our directors, informed the Board of his decision not to stand for re-election at our 2010 annual meeting of stockholders, which will be held on May 12, 2010. Mr. Murphy advised the Board that his decision was made for personal reasons and was not the result of any dispute or disagreement with us on any matter relating to our operations, policies or practices. Mr. Murphy currently serves as a member of the Compensation Committee and the Nominating and Corporate Governance Committee.

Our Corporate Governance Guidelines provide that no member of the Board shall be nominated by the Board to serve as a director after he has passed his 72nd birthday, unless the Board has voted to waive the mandatory retirement age of such person as a director. Timothy P. Horne, a member of our Board, will pass his 72nd birthday in April 2010, prior to our 2010 annual meeting of stockholders. On February 8, 2010, Mr. Horne advised the Board that he does not wish to have the Board waive the mandatory retirement age for him under our Corporate Governance Guidelines, and therefore Mr. Horne will also not stand for re-election at our 2010 annual meeting of stockholders.

On January 18, 2010, David J. Coghlan was promoted to Chief Operating Officer. In his new role, Mr. Coghlan will assume responsibility for our European operations in addition to his continuing responsibilities for our operations in North America and Asia. Mr. Coghlan has served as our President of North America and Asia since June 2008.

Net Sales. Our business is reported in three geographic segments: North America, Europe and China. Our net sales in each of these segments for the years ended December 31, 2009 and 2008 were as follows:

The organic decline in net sales in North America was primarily due to decreased unit sales of our plumbing and heating, backflow and gas connector product lines. Organic sales into the North American wholesale market in 2009 declined by 17.9% compared to 2008. This was primarily due to decreased unit sales across most of our product lines. Organic sales into the North American DIY market in 2009 increased 0.6% compared to 2008 primarily due to incremental product line penetration at certain retail customers and selected market share gains being offset by lower sales to certain customers.

Organic net sales declined in Europe primarily due to decreased sales in the European wholesale and OEM markets. Our sales into the European wholesale market in 2009 decreased by 13.5% and our sales into the European OEM market decreased by 15.7% compared to 2008 primarily due to the markets in Italy and Germany being soft. Acquired sales growth in Europe was due to the inclusion of Blücher Metal A/S (Blücher), which was acquired on May 30, 2008.

Organic net sales declined in China primarily due to decreased sales in the Chinese export markets. China sales were also negatively affected as compared to 2008 from the disposal of TWT during the fourth quarter of 2008.

The decreases in net sales due to foreign exchange in North America and Europe were primarily due to the depreciation of the Canadian dollar and the euro, respectively, against the U.S. dollar. We cannot predict whether these currencies will continue to depreciate against the U.S. dollar in future periods or whether future foreign exchange rate fluctuations will have a positive or negative impact on our net sales.

Gross Profit. Gross profit and gross profit as a percent of net sales (gross margin) for 2009 and 2008 were as follows:

Gross profit declined due to decreased sales volume, partially offset by increased gross margin. Gross margin increased by 180 basis points in 2009 compared to 2008 primarily due to lower raw material costs and fewer acquisition charges. Our European gross margin increased in 2009 compared to 2008 primarily due to the inclusion of higher margin Blücher sales and reduced acquisition costs, offset partially by plant under-absorption. Our China segment's gross margin increased as a result of operational improvements at one of our more significant facilities and the divestiture of TWT. Our North American margin also increased for 2009 when compared to last year due to lower raw material costs and cost savings initiatives offset by recessionary unit volume sales declines and plant under absorption.

Selling, General and Administrative Expenses. Selling, general and administrative expenses, or SG&A expenses, for 2009 decreased $32.1 million, or 9.0%, compared to 2008. The decrease in SG&A expenses is attributable to the following:

The organic decrease in SG&A expenses was primarily due to decreased variable selling expenses due to lower shipments, various cost savings measures, lower product liability costs and the net settlement of two lawsuits, partially offset by increased legal and pension expenses. The decrease in SG&A expenses from foreign exchange was primarily due to the depreciation of the euro against the U.S. dollar and to a lesser extent the Canadian dollar against the U.S. dollar. The increase in SG&A expenses from acquisitions was due to the inclusion of Blücher. The reduction due to the disposal relates to the sale of TWT. Total SG&A expenses, as a percentage of sales, were 26.4% in 2009 compared to 24.8% in 2008.

Restructuring and Other Charges. In 2009, we recorded a net charge of $16.1 million primarily for asset impairments, severance and relocation costs in North America, Europe and China. Included in the 2009 restructuring and other charges is a $1.1 million gain from the 2008 disposition of TWT. The gain was deferred until all legal and regulatory matters relating to the sale of TWT were resolved. In 2008, we recorded $5.6 million for severance and relocation costs in North America and China. See Note 4 of Notes to Consolidated Financial Statements in this Annual Report on Form 10-K, for additional information regarding our restructuring plans.

Goodwill and Other Indefinite-Lived Intangible Asset Impairment Charges. We recorded $3.3 million in 2009 for intangible impairment charges related to certain trademarks and technology. The goodwill impairment charge in 2008 of approximately $22.0 million related to our water quality business unit in North America. See Note 2 of Notes to Consolidated Financial Statements in this Annual Report on Form 10-K, for additional information regarding these impairments.

Operating Income. Operating income by geographic segment for 2009 and 2008 was as follows:

The decrease in consolidated organic operating income was due primarily to recessionary unit volume sales declines partially offset by stronger gross margins from lower raw material costs and from reductions in variable SG&A expenses such as commissions and shipping costs and from cost savings derived from various cost reduction programs. Corporate costs increased due to increased legal and pension costs, partially offset by the recovery of past legal expenses. The Blücher acquisition accounts for the net increase in operating profits from acquisitions. China's improved organic operating profit was due to operational improvements at one of our more significant facilities. China's operating profit from disposal was due to the divestiture of TWT.

The net decrease in operating income from foreign exchange was primarily due to the depreciation of the euro against the U.S. dollar and, to a lesser extent, the Canadian dollar against the U.S. dollar. We cannot predict whether these currencies will appreciate or depreciate against the U.S. dollar in future periods or whether future foreign exchange rate fluctuations will have a positive or negative impact on our operating income.

Interest Income. Interest income decreased $4.2 million, or 82.4%, in 2009 compared to 2008. This decrease was primarily a result of lower market interest rates.

Interest Expense. Interest expense decreased $4.2 million, or 16.0%, in 2009 compared to 2008, primarily due to a decrease in the average variable rates charged on the revolving credit facility and to a reduction in the amounts outstanding under the revolving credit facility.

Other (Income) Expense. Other expense decreased $10.7 million in 2009 compared to 2008, primarily because foreign currency transactions resulted in gains in 2009, while in 2008 losses were realized as a result of foreign currency movements primarily in Europe.

Income Taxes. Our effective rate for continuing operations increased to 43.3% from 36.3% in 2009 and 2008, respectively. The increase was primarily due to previously realized tax benefits in China, which are expected to be recaptured as a result of our decision to restructure our operations and intangible asset impairments that were not tax deductible. In North America, less tax exempt interest income was generated in 2009 as compared with 2008.

Net Income From Continuing Operations attributable to Watts Water Technologies, Inc. Net income from continuing operations attributable to Watts Water Technologies, Inc. in 2009 was $41.0 million, or $1.10 per common share, compared to $45.2 million, or $1.23 per common share, in 2008. Results for 2009 included after-tax charges totaling $18.1 million, or $0.49 per share, related to restructuring programs compared to an after-tax charge of $3.9 million, or $0.10 per share, for 2008. Also, results for 2009 included a non-cash net after-tax charge of $2.6 million, or $0.07 cents per share, to write off certain intangible assets. In 2008, net loss and loss from continuing operations attributable to Watts Water Technologies, Inc. included a non-cash after-tax charge of $17.3 million, or $0.47 cents per share, to write-off goodwill for one reporting unit. The depreciation of the euro and Canadian dollar against

the U.S. dollar resulted in a negative impact on our operations of $0.03 per common share in 2009 compared to last year. We cannot predict whether the euro, Canadian dollar or Chinese yuan will appreciate or depreciate against the U.S. dollar in future periods or whether future foreign exchange rate fluctuations will have a positive or negative impact on our net income.

Income (Loss) From Discontinued Operations. The income (loss) from discontinued operations was primarily attributable to the deconsolidation of TEAM and the loss on the disposal and loss from operations of CWV offset by the resolution of the James Jones Litigation as described in Note 3 of Notes to Consolidated Financial Statements, as described in Part I, Item 1. "Business—Product Liability, Environmental and Other Litigation Matters."

Net Sales. Our net sales in each of these segments for the years ended December 31, 2008 and 2007 were as follows:

Organic net sales for 2008 decreased in North America primarily due to decreased sales in the wholesale market, where sales were 2.5% lower than in 2007. Unit sale declines, due in large part to the soft economy, were widespread across a number of product lines, with our backflow product line impacted the most. Organic sales in our North American retail market for 2008 remained relatively flat compared with 2007, decreasing 0.6%. Unit sale reductions in the retail market due to the soft economy were offset by selected price increases and new product rollouts. Growth in North America due to acquisitions is due to the inclusion of sales from Topway Global Inc. (Topway), acquired in November 2007.

Organic net sales for 2008 increased in Europe primarily due to an 11.0% increase in sales into the European OEM market as compared to 2007. OEM sales were positively affected in Germany where sales of our products into alternative energy and energy conservation markets were strong. Sales into the wholesale market for 2008 decreased by 4.5% as compared to 2007 and were negatively affected by declines in construction activity. Acquired sales growth in Europe was due to the inclusion of Blücher for seven months in 2008.

Organic net sales for 2008 declined in China due to decreased sales in both the Chinese domestic and export markets. China sales were also negatively affected as compared to 2007 from the disposal of a commodity butterfly valve business during the fourth quarter of 2008. This decrease was partially

offset by an increase in sales of large diameter butterfly valves to our water infrastructure customers during 2008.

The increases in net sales due to foreign exchange in North America, Europe and China were primarily due to the appreciation of the Canadian dollar, euro and yuan, respectively, against the U.S. dollar.

Gross Profit. Gross profit and gross profit as a percent of net sales (gross margin) for 2008 and 2007 were as follows:

Gross margin improved by 20 basis points to 33.7% in 2008 compared to 2007. The improvement was attributable primarily to margin improvements in North America and Europe offset by declines in China. North America's margin improved 70 basis points to 34.4% primarily due to the price increases implemented to offset prior raw material cost increases and, to a lesser extent, the mix of products sold. North American gross margins in 2007 were negatively affected by approximately $6.5 million, or approximately 100 basis points on the prior year gross margin, for charges associated with product discontinuances and a change in estimate for workers' compensation costs. Gross margin in Europe increased to 32.8% from 31.4% primarily due to our ability to leverage additional volume from alternative energy product sales with better factory absorption levels due to the rationalization efforts made over the last two years in Italy. China gross margin deteriorated when compared to 2007 primarily due to excess capacity due to sales declines, value added tax increases, negative impact from the increase in the value of the Chinese yuan against the U.S. dollar and disruptions from a plant move and labor disputes.

Selling, General and Administrative Expenses. Selling, general and administrative expenses, or SG&A expenses, for 2008 increased $28.6 million, or 8.7%, compared to 2007. The increase in SG&A expenses is attributable to the following:

The organic increase in SG&A expenses was primarily due to increased incentive compensation costs and increased variable European selling expenses due to increased sales volumes partially offset by decreased shipping costs and other variable North American selling expenses due to decreased sales volumes. The increase in SG&A expenses from foreign exchange was primarily due to the appreciation of the euro, yuan and Canadian dollar against the U.S. dollar. The increase in SG&A expenses from acquisitions was due to the inclusion of Blücher and Topway. Total SG&A expenses, as a percentage of sales, was 24.8% in 2008 compared to 24.1% 2007.

Restructuring and Other Charges. In 2008, we recorded $5.6 million for severance, asset write-downs and accelerated depreciation in North America, China and Europe. In 2007, we recorded $3.2 million for asset write-downs, accelerated depreciation and severance in North America and China.

Goodwill and Other Indefinite-Lived Intangible Asset Impairment Charges. The goodwill impairment charge in 2008 of approximately $22.0 million related to our water quality business unit in North America. See Note 2 of Notes to Consolidated Financial Statements in this Annual Report on Form 10-K, for additional information regarding the impairment.

Operating Income. Operating income by geographic segment for 2008 and 2007 was as follows:

The decrease in consolidated organic operating income was due primarily to underutilization of capacity, in both China and, to a lesser extent, in North America caused by recessionary unit volume declines and one-off events in China such as the labor strike and a plant move. Also, SG&A expenses such as salaries, product liability costs and other fixed spending increased. These items were partially offset by higher sales and better productivity in Europe and reductions in certain SG&A expenses such as shipping, pension costs and bad debts. Corporate costs decreased as the result of lower benefit costs, including lower stock-based compensation and reduced costs from our nonqualified deferred compensation plan, and lower costs related to our Sarbanes Oxley compliance efforts and reduced legal costs.

The Blücher acquisition accounts for the net increase in operating profits from acquisitions.

The net increase in operating income from foreign exchange was primarily due to the appreciation of the euro against the U.S. dollar.

Interest Income. Interest income decreased $9.4 million, or 64.8%, in 2008 compared to 2007, primarily due to cash used to fund the Blücher acquisition and the stock buy-back program initiated in November 2007, as well as, a lower interest rate environment in 2008 as compared to 2007.

Interest Expense. Interest expense decreased $0.9 million, or 3.3%, in 2008 compared to 2007, primarily due to lower outstanding balances on the revolving credit facility partially offset by an increase in the average variable rates charged on the revolving credit facility.

Other (Income) Expense. Other expense increased $7.2 million, or 313.0%, in 2008 compared to 2007, primarily due to foreign currency transaction losses, losses on metal commodity transactions and negative changes in asset valuation of our nonqualified deferred compensation plan. Foreign currency transaction losses increased in China, Europe and Canada in 2008 as compared to 2007.

Income Taxes. Our effective tax rate for continuing operations increased to 36.3% for 2008 from 33.2% for 2007. The main driver of the increase was goodwill impairment. A portion of the goodwill relates to stock acquisitions, which when impaired is not tax deductible. Our European effective rate declined due to provision releases and favorable tax treatments related to the Blücher acquisition financing.

Net Income From Continuing Operations attributable to Watts Water Technologies, Inc. Net income from continuing operations attributable to Watts Water Technologies, Inc. in 2008 decreased $30.5 million, or 40.3%, to $45.2 million, or $1.23 per common share, from $75.7 million, or $1.94 per common share, for 2007, in each case, on a diluted basis. Repurchased shares had an accretive impact of $0.07 per common share in 2008. Income from continuing operations included an after-tax goodwill impairment charge of $17.3 million, or $0.47 per common share, for 2008. Income from continuing operations for 2007 included a tax refund of $1.9 million, or $0.05 per common share. Income from continuing operations for 2008 and 2007 included costs, net of tax, from our restructuring plan, reduction-in-force and product line discontinuances of $3.9 million, or $0.10 per common share, and $5.1 million, or $0.13 per common share, respectively. The appreciation of the euro, Chinese yuan and Canadian dollar against the U.S. dollar resulted in a positive impact on income from continuing operations of $0.07 per common share for 2008 compared to the comparable period last year.

Income From Discontinued Operations. Income from discontinued operations for 2008 and 2007 was primarily attributable to the operating income of CWV and TEAM being partially offset by increased legal fees associated with the James Jones Litigation, as described in Part I, Item 1. "Business—Product Liability, Environmental and Other Litigation Matters."

In 2009, we generated $204.6 million of cash from operating activities as compared to $145.0 million in 2008. We generated approximately $181.2 million of free cash flow (a non-GAAP financial measure, which we reconcile below, defined as net cash provided by continuing operating activities minus capital expenditures plus proceeds from sale of assets), which compares favorably to free cash flow of $119.9 million in 2008. Free cash flow as a percentage of net income from continuing operations attributable to Watts Water Technologies, Inc. was 442% in 2009 as compared to 265% in 2008 primarily due to better working capital management, temporary decreases in commodity costs, cash containment measures and careful monitoring of our capital spending.

In 2009, we used $21.3 million of net cash from investing activities primarily for purchases of capital equipment. We expect to invest approximately $31.0 in capital equipment in 2010 as part of our ongoing commitment to improve our manufacturing capabilities. We received proceeds of $1.7 million from the sale of auction rate securities. We received $1.1 million of cash for a purchase price settlement related to a prior-year acquisition. We paid $0.4 million for earn-out payments related to an acquisition from prior years.

As of December 31, 2009, we held $5.4 million in investments with an auction reset feature, or auction rate securities (ARS), with a total par value of $6.6 million. At the time of purchase, all the auction rate securities carried an AAA credit rating. These auction rate securities are all long-term debt obligations secured by municipal bonds and student loans. During the fourth quarter of 2008, we elected to participate in a settlement offer by UBS AG (UBS). Under the terms of the settlement, we were issued rights by UBS. Each right entitles the holder to sell the underlying ARS at par to UBS at any time during the period June 30, 2010, through July 2, 2012. UBS could elect at anytime from the

settlement date through July 2, 2012 to purchase the ARS at par value. The rights are valued at $1.1 million at December 31, 2009.

Liquidity for these ARS is typically provided by an auction process, which allows holders to sell their notes and resets the applicable interest rate at pre-determined intervals, usually every 7 to 35 days. Each of the auction rate securities in our investment portfolio as of December 31, 2009 has experienced failed auctions. There is no assurance that future auctions for these securities will succeed. We have classified the investment in ARS and the UBS rights as short-term investments as we will exercise our right to put the ARS on UBS at par on the earliest date possible.

We used $77.2 million of net cash from financing activities during 2009. This was primarily due to payments of debt and dividend payments.

We maintain a $350.0 million revolving credit facility with a syndicate of banks to support our acquisition program, working capital requirements and general corporate purposes. Outstanding indebtedness under the revolving credit facility bears interest at a rate determined by the type of loan plus an applicable margin determined by our debt rating, depending on the applicable base rate and our bond rating. For 2009, the average interest rate under the revolving credit facility for euro-based borrowings was approximately 2.2%. There were no borrowings under the credit facility at December 31, 2009.

Under our revolving credit facility, we are required to satisfy and maintain specified financial ratios and other financial condition tests. As of December 31, 2009, we were in compliance with all covenants related to the revolving credit facility. The financial ratios include a consolidated interest coverage ratio based on consolidated earnings before income taxes, interest expense, depreciation, and amortization ("Consolidated EBITDA") to consolidated interest expense, as defined in the revolving credit facility agreement. Our revolving credit facility defines Consolidated EBITDA to exclude unusual or non-recurring charges and gains. In addition, the definition excludes charges or gains associated with certain discontinued operations. We are also required to maintain a consolidated leverage ratio of consolidated funded debt to Consolidated EBITDA. Consolidated funded debt, as defined in the revolving credit facility agreement, includes all long and short-term debt, capital lease obligations and any trade letters of credit that are outstanding. Finally, we are required to maintain a consolidated net worth that exceeds a minimum net worth calculation. Consolidated net worth is defined as the total stockholders' equity as reported adjusted for any cumulative translation adjustments.

As of December 31, 2009, our actual financial ratios calculated in accordance with our revolving credit facility compared to the required levels under our revolving credit facility were as follows:

As of December 31, 2009, our actual financial ratio calculated in accordance with our senior note agreements compared to the required levels under our senior note agreements were as follows:

In addition to the above financial ratios, the revolving credit facility and senior note agreements contain affirmative and negative covenants that include limitations on disposition or sale of assets, prohibitions on assuming or incurring any liens on assets with limited exceptions and limitations on making investments other than those permitted by the agreements.

We have several note agreements as further detailed in Note 11 of Notes to Consolidated Financial Statements. These note agreements require us to maintain a fixed charge coverage ratio of consolidated EBITDA plus consolidated rent expense during the period to consolidated fixed charges. Consolidated fixed charges are the sum of consolidated interest expense for the period and consolidated rent expense.

As of December 31, 2009, we had $314.4 million of unused credit under the revolving credit facility and $35.6 million for stand-by letters of credit outstanding on our revolving credit facility. Due primarily to the consolidated leverage ratio, we could borrow approximately $108.5 million under the existing facility, excluding the stand-by-letters of credit, before we would violate one of the above covenants.

We used $21.2 million of net cash from operating activities of discontinued operations in 2009 primarily due to the settlement of $15.3 million related to the James Jones litigation. In addition, separate from the settlement, we paid our outside counsel an additional $5.0 million for services rendered in connection with the litigation.

We used $0.3 million of net cash from investing activities of discontinued operations in 2009 primarily due to purchasing capital equipment.

Working capital (defined as current assets less current liabilities) as of December 31, 2009 was $489.8 million compared to $497.8 million as of December 31, 2008. This decrease was primarily due to reductions in inventory and accounts receivable and the classification of our $50 million 4.87% notes due in May 2010 to current liabilities offset by the increase in cash. Although, we are currently exploring alternatives in refinancing these notes, we have the ability to pay off this debt with our available cash. Cash and cash equivalents increased to $258.2 million as of December 31, 2009 compared to $165.6 million as of December 31, 2008 primarily due to fewer acquisitions costs in 2009 and to better working capital management. The ratio of current assets to current liabilities was 2.6 to 1 as of December 31, 2009 compared to 2.7 to 1 as of December 31, 2008.

In 2008, we generated $145.0 million of cash from operating activities as compared to $90.0 million in 2007. With management's enhanced focus in 2008 on working capital management, net working capital cash outflows decreased from $22.8 million in 2007, to a net working capital cash inflow of $45.5 million in 2008, a $68.3 million positive change. Better overall management of our inventory, accounts receivable and accounts payable drove the improvement in working capital. This change was offset to some extent by lower income from continuing operations.

We used $170.0 million of net cash for investing activities in 2008. We used approximately $167.9 million of net cash to fund the acquisition of Blücher and we spent $7.6 million for acquisition costs related to prior years acquisitions. We received proceeds of $33.3 million from the sale of auction rate securities. We invested $26.2 million in capital equipment as part of our ongoing commitment to improve our manufacturing capabilities.

We used $92.4 million of net cash from financing activities in 2008. This was primarily due to payments for our stock repurchase program, payments of debt and dividend payments, partially offset by increased borrowings under our line of credit.

We generated $0.8 million of net cash from operating activities of discontinued operations in 2008 primarily attributable to TEAM and CWV partially offset by approximately $1.2 million for defense and other legal costs we incurred in the James Jones Litigation. We also received $1.3 million for reimbursements of defense costs.

We used $2.2 million of net cash from investing activities of discontinued operations in 2008 primarily due to acquisition costs related to TEAM and to purchase capital equipment.

We generated $90.0 million of cash from operating activities in 2007. We experienced increases in inventory in North America and China. The increases were primarily due to increased raw material costs. There was also a decrease in accounts payable, accrued expenses and other liabilities, primarily in Europe and North America. In Europe, accounts payable declined in 2007 due to a decline in inventory. In North America, payments for cash compensation increased in 2007. Also, cash payments to cover income tax obligations were greater during 2007. Accounts receivable decreased in all three segments.

We used $84.7 million of net cash for investing activities in 2007. We invested $36.9 million in capital equipment as part of our ongoing commitment to improve our manufacturing capabilities. We invested $27.5 million in auction rate securities. We used $18.1 million to fund the acquisition of Topway. We paid $3.2 million for additional acquisition costs related to prior years acquisitions.

We used $66.5 million of net cash from financing activities in 2007. This was primarily due to payments of debt, payments for our stock repurchase program and dividend payments, partially offset by increased borrowings under our line of credit and tax benefits from the exercise of stock awards.

We generated $1.8 million of net cash from operating activities of discontinued operations in 2007 primarily attributable to CWV and TEAM. We paid approximately $0.5 million for defense costs and approximately $0.5 million for other legal costs incurred in the James Jones Litigation. We also received $1.0 million in indemnity payments.

We used $2.7 million of net cash from investing activities of discontinued operations in 2007 primarily due to acquisition costs related to CWV and to purchase capital equipment.

Our net debt to capitalization ratio (a non-GAAP financial measure, as reconciled below, defined as short and long-term interest-bearing liabilities less cash and cash equivalents as a percentage of the sum of short and long term interest-bearing liabilities less cash and cash equivalents plus total stockholders' equity) decreased to 9.9% for 2009 from 22.8% for 2008. The decrease resulted from decreased borrowings under our line of credit and increased cash.

We believe free cash flow to be an appropriate supplemental measure of our operating performance because it provides investors with a measure of our ability to generate cash, to repay debt and to fund acquisitions. We may not be comparable to other companies that may define free cash flow differently. Free cash flow does not represent cash generated from operating activities in accordance with GAAP. Therefore it should not be considered an alternative to net cash provided by operations as an indication of our performance. Free cash flow should also not be considered an alternative to net cash provided by operations as defined by GAAP.

A reconciliation of net cash provided by continuing operations to free cash flow is provided below:

Our net debt to capitalization ratio is also a non-GAAP financial measure used by management. Management believes it to be an appropriate supplemental measure because it helps investors understand our ability to meet our financing needs and as a basis to evaluate our financial structure. Our computation may not be comparable to other companies that may define net debt to capitalization differently.

A reconciliation of long-term debt (including current portion) to net debt and our net debt to capitalization ratio is provided below:

Our contractual obligations as of December 31, 2009 are presented in the following table:

We maintain letters of credit that guarantee our performance or payment to third parties in accordance with specified terms and conditions. Amounts outstanding were approximately $37.0 million as of December 31, 2009 and $39.3 million as of December 31, 2008. Our letters of credit are primarily associated with insurance coverage and to a lesser extent foreign purchases and generally expire within one year of issuance. These instruments may exist or expire without being drawn down, therefore they do not necessarily represent future cash flow obligations.

Except for operating lease commitments, we have no off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

The preparation of our consolidated financial statements in accordance with U.S. GAAP requires management to make judgments, assumptions and estimates that affect the amounts reported. A critical accounting estimate is an assumption about highly uncertain matters and could have a material effect on the consolidated financial statements if another, also reasonable, amount were used, or, a change in the estimate is reasonably likely from period to period. We base our assumptions on historical experience and on other estimates that we believe are reasonable under the circumstances. Actual results could differ significantly from these estimates. There were no changes in our accounting policies or significant changes in our accounting estimates during 2009.

We periodically discuss the development, selection and disclosure of the estimates with our Audit Committee. Management believes the following critical accounting policies reflect its more significant estimates and assumptions.

We recognize revenue when all of the following criteria are met: (1) we have entered into a binding agreement, (2) the product has shipped and title has passed, (3) the sales price to the customer is fixed or is determinable and (4) collectability is reasonably assured. We recognize revenue based upon a determination that all criteria for revenue recognition have been met, which, based on the majority of our shipping terms, is considered to have occurred upon shipment of the finished product. Some shipping terms require the goods to be received by the customer before title passes. In those instances, revenues are not recognized until the customer has received the goods. We record estimated reductions to revenue for customer returns and allowances and for customer programs. Provisions for returns and allowances are made at the time of sale, derived from historical trends and form a portion of the allowance for doubtful accounts. Customer programs, which are primarily annual volume incentive plans, allow customers to earn credit for attaining agreed upon purchase targets from us. We record estimated reductions to revenue, made at the time of sale, for customer programs based on estimated purchase targets.

The allowance for doubtful accounts is established to represent our best estimate of the net realizable value of the outstanding accounts receivable. The development of our allowance for doubtful accounts varies by region but in general is based on a review of past due amounts, historical write-off experience, as well as aging trends affecting specific accounts and general operational factors affecting all accounts. In North America, management specifically analyzes individual accounts receivable and establishes specific reserves against financially troubled customers. In addition, factors are developed utilizing historical trends in bad debts, returns and allowances. The ratio of these factors to sales on a rolling twelve-month basis is applied to total outstanding receivables (net of accounts specifically identified) to establish a reserve. In Europe, management develops its bad debt allowance through an aging analysis of all their accounts. In China, management specifically analyzes individual accounts receivable and establishes specific reserves as needed along with providing reserves based on aging analysis.

We uniformly consider current economic trends and changes in customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. We also aggressively monitor the creditworthiness of our largest customers, and periodically review customer credit limits to reduce risk. If circumstances relating to specific customers change or unanticipated changes occur in the general business environment, our estimates of the recoverability of receivables could be further adjusted.

Inventories are stated at the lower of cost or market with costs determined primarily on a first-in first-out basis. We utilize both specific product identification and historical product demand as the basis for determining our excess or obsolete inventory reserve. We identify all inventories that exceed a range of one to four years in sales. This is determined by comparing the current inventory balance against unit sales for the trailing twelve months. New products added to inventory within the past twelve months are excluded from this analysis. A portion of our products contain recoverable materials, therefore the excess and obsolete reserve is established net of any recoverable amounts. Changes in market conditions, lower-than-expected customer demand or changes in technology or features could result in additional obsolete inventory that is not saleable and could require additional inventory reserve provisions.

In certain countries, additional inventory reserves are maintained for potential shrinkage experienced in the manufacturing process. The reserve is established based on the prior year's inventory losses adjusted for any change in the gross inventory balance.

We have made numerous acquisitions over the years which included the recognition of a significant amount of goodwill. Goodwill is tested for impairment annually or more frequently if an event or circumstance indicates that an impairment loss may have been incurred. Application of the goodwill impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units, and determination of the fair value of each reporting unit. In 2008 and 2009, we estimated the fair value of our reporting units using an income approach based on the present value of estimated future cash flows. We believe this approach yields the most appropriate evidence of fair value as our reporting units are not easily compared to other corporations involved in similar businesses.

Intangible assets such as purchased technology are generally recorded in connection with a business acquisition. Values assigned to intangible assets are determined by an independent valuation firm based on our estimates and judgments regarding expectations of the success and life cycle of products and technology acquired. As of our October 25, 2009 testing date, we determined we had seven reporting units in continuing operations, one which had no goodwill.

We review goodwill for impairment utilizing a two-step process. The first step of the impairment test requires a comparison of the fair value of each of our reporting units to the respective carrying value. If the carrying value of a reporting unit is less than its fair value, no indication of impairment exists and a second step is not performed. If the carrying amount of a reporting unit is higher than its fair value, there is an indication that an impairment may exist and a second step must be performed. In the second step, the impairment is computed by comparing the implied fair value of the reporting unit's goodwill with the carrying amount of the goodwill. If the carrying amount of the reporting unit's goodwill is greater than the implied fair value of its goodwill, an impairment loss must be recognized for the excess and charged to operations.

Inherent in our development of the present value of future cash flow projections are assumptions and estimates derived from a review of our operating results, business plans, expected growth rates, cost of capital and tax rates. We also make certain assumptions about future economic conditions and other market data. We develop our assumptions based on our historical results including sales growth, operating profits, working capital levels and tax rates.

We believe that the discounted cash flow model is sensitive to the selected discount rate. We use third-party valuation specialists to help develop appropriate discount rates for each reporting unit. We use standard valuation practices to arrive at a weighted average cost of capital based on the market and guideline public companies. The higher the discount rate, the lower the discounted cash flows. While we believe that our estimates of future cash flows are reasonable, different assumptions could significantly affect our valuations and result in impairments in the future.

During 2009, we recognized a non-cash pre-tax charge of approximately $3.3 million as an impairment of some of the indefinite lived intangible assets.

During the fourth quarter of 2008, we recognized an aggregate non-cash goodwill impairment charge of $22.0 million related to our water quality business unit within our North America segment. The charge reflected the challenges of the residential construction cycle, as well as the broader economic and credit environment.

As of our October 25, 2009 testing date, we had approximately $435.8 million of goodwill on our balance sheet. Our impairment testing indicated that the fair values of the reporting units exceeded the

carrying values, thereby resulting in no impairment. The results of this impairment analysis are summarized in the table below:

The underlying analyses supporting our fair value assessment related to our outlook of the business' long-term performance, which included key assumptions as to the appropriate discount rate and long-term growth rate. In connection with our October 25, 2009 impairment test, we utilized discount rates ranging from 11.3% to 15% and long-term terminal growth rates from 3% to 5% beyond our planning periods.

Because of retention requirements associated with our insurance policies, we are generally self-insured for potential product liability claims and for workers' compensation costs associated with workplace accidents. For product liability cases in the U.S., management estimates expected settlement costs by utilizing loss reports provided by our third-party administrators as well as developing internal historical trend factors based on our specific claims experience. Management utilizes the internal trend factors that reflect final expected settlement costs. In other countries, we maintain insurance coverage with relatively high deductible payments, as product liability claims tend to be smaller than those experienced in the U.S. Changes in the nature of claims or the actual settlement amounts could affect the adequacy of this estimate and require changes to the provisions. Because the liability is an estimate, the ultimate liability may be more or less than reported.

Workers' compensation liabilities in the U.S. are recognized for claims incurred (including claims incurred but not reported) and for changes in the status of individual case reserves. At the time a workers' compensation claim is filed, a liability is estimated to settle the claim. The liability for workers' compensation claims is determined based on management's estimates of the nature and severity of the claims and based on analysis provided by third-party administrators and by various state statutes and reserve requirements. We have developed our own trend factors based on our specific claims experience, discounted based on risk-free interest rates. In other countries where workers' compensation costs are applicable, we maintain insurance coverage with limited deductible payments. Because the liability is an estimate, the ultimate liability may be more or less than reported and is subject to changes in discount rates.

We determine the trend factors for product liability and workers' compensation liabilities based on consultation with outside actuaries.

We maintain excess liability insurance with outside insurance carriers to minimize our risks related to catastrophic claims in excess of all self-insured positions. Any material change in the aforementioned factors could have an adverse impact on our operating results.

We are a defendant in numerous legal matters including those involving environmental law and product liability as discussed in more detail in Part I, Item 1. "Business—Product Liability, Environmental and Other Litigation Matters." As required by GAAP, we determine whether an

estimated loss from a loss contingency should be accrued by assessing whether a loss is deemed probable and the loss amount can be reasonably estimated, net of any applicable insurance proceeds. Estimates of potential outcomes of these contingencies are developed in consultation with outside counsel. While this assessment is based upon all available information, litigation is inherently uncertain and the actual liability to fully resolve this litigation cannot be predicted with any assurance of accuracy. Final resolution of these matters could possibly result in significant effects on our results of operations, cash flows and financial position.

We account for our pension plans in accordance with GAAP, which involves recording a liability or asset based on the projected benefit obligation and the fair value of plan assets. Assumptions are made regarding the valuation of benefit obligations and the performance of plan assets. The primary assumptions are as follows:

We determine these assumptions based on consultation with outside actuaries and investment advisors. Any variance in these assumptions could have a significant impact on future recognized pension costs, assets and liabilities.

We estimate and use our expected annual effective income tax rates to accrue income taxes. Effective tax rates are determined based on budgeted earnings before taxes, including our best estimate of permanent items that will affect the effective rate for the year. Management periodically reviews these rates with outside tax advisors and changes are made if material variances from expectations are identified.

We recognize deferred taxes for the expected future consequences of events that have been reflected in the consolidated financial statements. Deferred tax assets and liabilities are determined based on differences between the book values and tax bases of particular assets and liabilities, using tax rates in effect for the years in which the differences are expected to reverse. A valuation allowance is provided to offset any net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. We consider estimated future taxable income and ongoing prudent tax planning strategies in assessing the need for a valuation allowance.

In October 2009, the Financial Accounting Standards Board (FASB) issued an accounting standard update to improve disclosures related to fair value measurements. This update will require new disclosures when significant transfers in and out of the various fair value levels occur. This update will require a reconciliation for fair value measurements using significant unobservable inputs (level 3) be prepared on a gross basis, separately presenting information about purchases, sales, issuance and settlements. In addition, this update will amend current disclosure requirements for postretirement benefit plan assets. This update will be effective for interim and annual periods beginning after December 15, 2009, except for disclosures regarding level 3 fair value measurements. Those disclosures are effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years. We are evaluating the impact that this update will have but do not expect the adoption to have a material impact on our consolidated financial statements.

In October 2009, FASB issued an accounting standard update to address accounting for multiple-deliverable arrangements, specifically addressing how to separate deliverables and how to measure and allocate arrangement consideration to one or more units of accounting. This update established a hierarchy for determining the selling price of a deliverable. This standard also expands disclosures relating to an entity's multiple-deliverable revenue arrangements. This update is effective prospectively for all arrangements entered into or materially modified in fiscal years beginning after June 15, 2010. The adoption of this update is not expected to have a material impact on our consolidated financial statements.

In June 2009, FASB issued a new standard which identifies the sources of accounting principles and the framework for selecting the principles used in the preparation of financial statements that are presented in conformity with generally accepted accounting principles (GAAP) in the United States (the GAAP hierarchy). This standard also establishes the FASB Accounting Standards Codification (ASC) as the source of authoritative accounting principles recognized by the FASB to be applied in the preparation of non-governmental financial statements. This standard is effective for all interim and annual financial statements issued after September 15, 2009. The adoption of this standard did not have a material impact on our consolidated financial statements.

In June 2009, FASB issued a new standard which requires an entity to perform an analysis to determine whether the variable interest or interests give it a controlling financial interest. This statement also requires an entity to regularly reassess whether the entity has a controlling financial interest in the variable interest or interests. This statement will also expand disclosures on variable interest or interests in the footnotes. This standard is effective for the first annual reporting period beginning after November 15, 2009 as well as the interim period therein. The adoption of this standard did not have a material impact on our consolidated financial statements.

In June 2009, FASB issued a new standard which eliminates the concept of a qualifying special-purpose entity as defined in other GAAP literature. This statement also establishes more stringent conditions for reporting a transfer of a portion of a financial asset as a sale and changes the initial measurement of a transferor's interest in transferred financial assets. This statement expands disclosures for interim and annual reports and is effective for the first annual reporting period beginning after November 15, 2009. The adoption of this standard did not have a material impact on our consolidated financial statements

We use derivative financial instruments primarily to reduce exposure to adverse fluctuations in foreign exchange rates, interest rates and costs of certain raw materials used in the manufacturing process. We do not enter into derivative financial instruments for trading purposes. As a matter of policy, all derivative positions are used to reduce risk by hedging underlying economic exposure. The derivatives we use are instruments with liquid markets.

Our consolidated earnings, which are reported in United States dollars, are subject to translation risks due to changes in foreign currency exchange rates. This risk is concentrated in the exchange rate between the U.S. dollar and the euro; the U.S. dollar and the Canadian dollar; and the U.S. dollar and the Chinese yuan.

Our foreign subsidiaries transact most business, including certain intercompany transactions, in foreign currencies. Such transactions are principally purchases or sales of materials and are denominated in European currencies or the U.S. or Canadian dollar. We use foreign currency forward exchange contracts to manage the risk related to intercompany purchases that occur during the course of a year and certain open foreign currency denominated commitments to sell products to third parties. For 2009, the amounts recorded in other income for the change in the fair value of such contracts was immaterial.

We have historically had a low exposure on the cost of our debt to changes in interest rates. Information about our long-term debt including principal amounts and related interest rates appears in Note 11 of Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2009.

We purchase significant amounts of bronze ingot, brass rod, cast iron, steel and plastic, which are utilized in manufacturing our many product lines. Our operating results can be adversely affected by changes in commodity prices if we are unable to pass on related price increases to our customers. We manage this risk by monitoring related market prices, working with our suppliers to achieve the maximum level of stability in their costs and related pricing, seeking alternative supply sources when necessary and passing increases in commodity costs to our customers, to the maximum extent possible, when they occur.

During 2008, we entered into a series of copper swap contracts to fix the price per pound of copper for one customer which expired in 2009. These swaps are classified as economic hedges, as more fully explained in Note 16 of Notes to the Consolidated Financial Statements. For the period ended December 31, 2009 and 2008, we recorded a $0.3 million gain and $1.6 million loss, respectively, associated with the copper swaps in other expense.

We used a discounted cash flow model for determining the value of the ARS and the UBS rights. As there is no active market for the ARS and the rights are non-transferable, we believe that the discounted cash flow model gives the best estimate of fair value at December 31, 2009 and 2008. The model includes assumptions that are more fully explained in Note 16 of Notes to the Consolidated Financial Statements. The most sensitive of these assumptions is the illiquidity spread. We engaged valuation experts to develop the models. The illiquidity spread increases the discount rate, thereby decreasing the estimated fair value. To value the rights issued by UBS, we used a discounted cash flow model to estimate the fair value based on the assumption we will exercise our option at the earliest convenience. While we believe the assumptions used are consistent with the current market view on the ARS and are reasonable, different assumptions could significantly affect our valuation of ARS.

Item 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE.

As required by Rule 13a-15(b) under the Securities Exchange Act of 1934, as of the end of the period covered by this report, we carried out an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures. In designing and evaluating our disclosure controls and procedures, we recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management necessarily applies its judgment in evaluating and implementing possible controls and procedures. The effectiveness of our disclosure controls and procedures is also necessarily limited by the staff and other resources available to us and the geographic diversity of our operations. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective, in that they provide reasonable assurance that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms and are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act are accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. There was no change in our internal control over financial reporting that occurred during the quarter ended December 31, 2009, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. In connection with these rules, we will continue to review and document our disclosure controls and procedures, including our internal control over financial reporting, and may from time to time make changes aimed at enhancing their effectiveness and to ensure that our systems evolve with our business.

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. The Company's internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company's internal control over financial reporting includes those policies and procedures that:

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management, including our Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2009. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework.

Based on our assessment and those criteria, management believes that the Company maintained effective internal control over financial reporting as of December 31, 2009.

The independent registered public accounting firm that audited the Company's consolidated financial statements included elsewhere in this Annual Report on Form 10-K has issued an attestation report on the Company's internal control over financial reporting. That report appears immediately following this report.

We have audited Watts Water Technologies, Inc.'s internal control over financial reporting as of December 31, 2009, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Watts Water Technologies, Inc.'s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

In our opinion, Watts Water Technologies, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2009, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Watts Water Technologies, Inc. and subsidiaries as of December 31, 2009 and 2008, and the related consolidated statements of operations, stockholders' equity and comprehensive income (loss), and cash flows for each of the years in the three-year period ended December 31, 2009, and our report dated March 1, 2010 expressed an unqualified opinion on those consolidated financial statements.

We have audited the accompanying consolidated balance sheets of Watts Water Technologies, Inc. and subsidiaries as of December 31, 2009 and 2008, and the related consolidated statements of operations, stockholders' equity and comprehensive income (loss), and cash flows for each of the years in the three-year period ended December 31, 2009. In connection with our audits of the consolidated financial statements, we also have audited the financial statement schedule. These consolidated financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Watts Water Technologies, Inc. and subsidiaries as of December 31, 2009 and 2008, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2009, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Watts Water Technologies, Inc.'s internal control over financial reporting as of December 31, 2009, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 1, 2010 expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting.

Notes to Consolidated Financial Statements

Watts Water Technologies, Inc. (the Company) designs, manufactures and sells an extensive line of water safety and flow control products primarily for the water quality, water conservation, water safety and water flow control markets located predominantly in North America, Europe, and China.

The consolidated financial statements include the accounts of the Company and its majority and wholly owned subsidiaries. Upon consolidation, all significant intercompany accounts and transactions are eliminated.

Cash equivalents consist of instruments with remaining maturities of three months or less at the date of purchase and consist primarily of money market funds, for which the carrying amount is a reasonable estimate of fair value.

Investment securities at December 31, 2009 and 2008 consisted of auction rate securities (ARS) whose underlying investments were in municipal bonds and student loans and investments in rights issued by UBS, AG (UBS). The securities were purchased at par value. The rights issued by UBS were received in connection with a settlement agreement. See Note 16 for additional information regarding the rights issued by UBS. The Company classified its debt securities and investment in rights from UBS as trading securities.

Trading securities are recorded at fair value. The Company determines the fair value by obtaining market value when available from quoted prices in active markets. In the absence of quoted prices, the Company uses other inputs to determine the fair value of the investments. All changes in the fair value as well as any realized gains and losses from the sale of the securities are recorded when incurred to the consolidated statements of operations as other income or expense.

Allowance for doubtful accounts includes reserves for bad debts and sales returns and allowances. The Company analyzes the aging of accounts receivable, individual accounts receivable, historical bad debts, concentration of receivables by customer, customer credit worthiness, current economic trends and changes in customer payment terms. The Company specifically analyzes individual accounts receivable and establishes specific reserves against financially troubled customers. In addition, factors are developed in certain regions utilizing historical trends of sales and returns and allowances to derive a reserve for returns and allowances.

The Company sells products to a diversified customer base and, therefore, has no significant concentrations of credit risk. In 2009 and 2008, no one customer accounted for 10.0% or more of the Company's total sales.

Inventories are stated at the lower of cost (using primarily the first-in, first-out method) or market. Market value is determined by replacement cost or net realizable value. Historical experience is used as the basis for determining the reserve for excess or obsolete inventories.

Goodwill is recorded when the consideration paid for acquisitions exceeds the fair value of net tangible and intangible assets acquired. Goodwill and other intangible assets with indefinite useful lives are not amortized, but rather are tested annually for impairment. The test was performed as of October 25, 2009.

The Company accounts for assets held for sale when management has committed to a plan to sell the asset or group of assets, is actively marketing the asset or group of assets, the asset or group of assets can be sold in its current condition in a reasonable period of time and the plan is not expected to change. As of December 31, 2009, the Company is actively marketing two properties and one group of assets worldwide and expects to complete the sale of these assets or group of assets in the next twelve months. The Company recorded estimated losses of $7.8 million to reduce these assets or group of assets down to their estimated fair value, less any costs to sell. This amount is recorded as a component of restructuring and other costs in the consolidated statements of operations. See Note 4 for additional information associated with the Company's restructuring charges.

The changes in the carrying amount of goodwill by geographic segment are as follows:

In 2008, the Company completed an assessment of the fair value of the net assets of its water quality business unit, which includes a number of businesses that were purchased over time, and recorded a pre-tax goodwill impairment charge of $22.0 million due to sales declining from prior year levels and from the Company's expectations of lower commercial and residential project activity. The Company estimated the fair value of the reporting unit using the expected present value of future cash flows.

In February 2009, the Company reached a settlement with the seller regarding a purchase price adjustment to the Core Industries, Inc. acquisition that resulted in the Company receiving $1.1 million. In May 2009, the Company deconsolidated TEAM Precision Pipework, Ltd. (TEAM). As a result of the deconsolidation, the Company reduced goodwill by $8.4 million associated with TEAM. See Note 3 for additional information relating to the deconsolidation of TEAM. In September 2009, the Company's Board of Directors approved a plan to dispose of its investment in Watts Valve (Changsha) Co., Ltd. (CWV), an indirect wholly-owned subsidiary of the Company located in China. The Company classified the net assets of CWV as a discontinued operation and recorded a decrease in the net assets to their estimated fair value less costs to sell. As a result, the Company reduced goodwill by $6.1 million associated with CWV. See Note 3 and Note 5 for additional information relating to CWV.

Goodwill is tested for impairment at least annually or more frequently if events or circumstances indicate that it is "more likely than not" that goodwill might be impaired, such as a change in business conditions. The Company performs its annual goodwill impairment assessment in the fourth quarter of each year.

Intangible assets with estimable lives and other long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability of intangible assets with estimable lives and other long-lived assets is measured by a comparison of the carrying amount of an asset or asset group to future net undiscounted pretax cash flows expected to be generated by the asset or asset group. If these comparisons indicate that an asset is not recoverable, the impairment loss recognized is the amount by which the carrying amount of the asset or asset group exceeds the related estimated fair value. Estimated fair value is based on either discounted future pretax operating cash flows or appraised values, depending on the nature of the asset. The Company determines the discount rate for this analysis based on the expected internal rate of return for the related business and does not allocate interest charges to the asset or asset group being measured. Judgment is required to estimate future operating cash flows.

In connection with the restructuring plan announced in February 2009, the Company will be closing several facilities to reduce the overall size of its manufacturing footprint. The Company concluded that it is more likely than not that the carrying amount of certain assets held and used may not be recoverable. Specifically, the Company identified a long-lived asset group primarily comprised of buildings and land use rights in China. The Company used an undiscounted future cash flow model to test the long-lived asset group based on the primary asset identified, the current economic outlook and the estimated fair value from the ultimate disposition of the asset group. The inputs used in this analysis are unobservable inputs (level 3). Based on the analysis performed, the Company recorded a $5.5 million impairment charge for one asset group in China during the quarter ended September 27, 2009. This charge is reported in restructuring and other charges in the consolidated statements of operations.

In connection with the plan to dispose of CWV, certain long-lived assets were reduced by $3.9 million to reflect their estimated fair value less cost to sell. This charge was recorded in discontinued operations as part of the $8.5 million loss on disposal.

Aggregate amortization expense for amortized intangible assets for 2009, 2008 and 2007 was $13.1 million, $12.2 million and $9.2 million, respectively. Additionally, future amortization expense on amortizable intangible assets is expected to be $13.1 million for 2010, $12.7 million for 2011, $10.3 million for 2012, $9.9 million for 2013, and $9.7 million for 2014. Amortization expense is provided on a straight-line basis over the estimated useful lives of the intangible assets. The weighted-average remaining life of total amortizable intangible assets is 10.2 years. Patents, customer relationships, technology and other amortizable intangibles have weighted-average remaining lives of 8.2 years, 9.2 years, 15.2 years and 14.1 years, respectively. Intangible assets not subject to amortization primarily include trademarks.

Adjustments to indefinite lived intangible assets during the year ended December 31, 2009 relate primarily to a reclassification of one technology related intangible asset and the results from the annual impairment analysis evaluation performed as of October 25, 2009. The Company had previously classified a technology intangible asset as an indefinite lived intangible asset as it could not determine the time horizon over which that asset was expected to be used. During 2009, the Company concluded that this technology asset no longer has an indefinite life due in part to recent competition and changes in regulations. As a result, the Company increased technology amortizable intangible assets and reduced intangible assets not subject to amortization by approximately $7.5 million. The Company uses a royalty relief method to evaluate the current fair value of its trademarks and technology. Due to the decreases in sales experienced in several of its brands and technology in 2009 as well as the estimated outlook for future sales of these brands and technology, the Company recorded a pre-tax charge of $3.3 million to decrease these assets to their estimated fair value.

Property, plant and equipment are recorded at cost. Depreciation is provided on a straight-line basis over the estimated useful lives of the assets, which range from 10 to 40 years for buildings and improvements and 3 to 15 years for machinery and equipment.

Taxes assessed by governmental authorities on sale transactions are recorded on a net basis and excluded from sales, in the Company's consolidated statements of operations.

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

The Company accounts for tax benefits when the item in question meets the more-likely-than-not (greater than 50% likelihood of being sustained upon examination by the taxing authorities) threshold. During 2009, the Company reduced its unrecognized tax benefits by approximately $0.6 million as a result of finalizing the federal tax audit and by $0.4 million resulting from voluntary disclosure agreements. The Company estimates that it is reasonably possible that a portion of the currently remaining unrecognized tax benefit may be recognized by the end of 2011 as a result of the conclusion of federal and foreign income tax audits. The amount of expense accrued for penalties and interest is $0.5 million worldwide.

As of December 31, 2009, the Company had gross unrecognized tax benefits of approximately $2.8 million of which, approximately $2.5 million, if recognized, would affect the effective tax rate. The difference between the amount of unrecognized tax benefits and the amount that would impact the effective tax rate consists of the federal tax benefit of state income tax items. A reconciliation of the beginning and ending amount of unrecognized tax benefits and a separate analysis of accrued interest related to the unrecognized tax benefits is as follows:

The Company is currently under audit by the Internal Revenue Service for the 2008 and 2007 tax years. The expected completion date for these audits is March 2011. The Company does not anticipate any significant adjustments at this time. Watts conducts business in a variety of locations throughout the world resulting in tax filings in numerous domestic and foreign jurisdictions. The Company is subject to tax examinations regularly as part of the normal course of business. The Company's major jurisdictions are the U.S., Canada, China, Netherlands, U.K., Germany, Italy and France. With few exceptions the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations for years before 2003.

The Company accounts for interest and penalties related to uncertain tax positions as a component of income tax expense.

The statute of limitations in our major jurisdictions is open in the U.S. for the year 2006 and later; in Canada for 2005 and later; and in the Netherlands for 2005 and later.

The financial statements of subsidiaries located outside the United States generally are measured using the local currency as the functional currency. Balance sheet accounts, including goodwill, of foreign subsidiaries are translated into United States dollars at year-end exchange rates. Income and expense items are translated at weighted average exchange rates for each period. Net translation gains or losses are included in other comprehensive income, a separate component of stockholders' equity. The Company does not provide for U.S. income taxes on foreign currency translation adjustments since it does not provide for such taxes on undistributed earnings of foreign subsidiaries. Gains and losses from foreign currency transactions of these subsidiaries are included in net earnings.

The Company records compensation expense in the financial statements for share-based awards based on the grant date fair value of those awards. Stock-based compensation expense includes an estimate for pre-vesting forfeitures and is recognized over the requisite service periods of the awards on a straight-line basis, which is generally commensurate with the vesting term. The benefits associated with tax deductions in excess of recognized compensation cost are reported as a financing cash flow.

At December 31, 2009, the Company had three stock-based compensation plans with total unrecognized compensation costs related to unvested stock-based compensation arrangements of approximately $7.7 million and a total weighted average remaining term of 2.4 years. For 2009, 2008 and 2007, the Company recognized compensation costs related to stock-based programs of approximately $4.9 million, $5.3 million and $6.0 million respectively, in selling, general and administrative expenses. The Company recorded approximately $0.6 million, $0.7 million and $0.7 million of tax benefits during 2009, 2008 and 2007, respectively, for the compensation expense relating to its stock options. For 2009, 2008 and 2007, the Company recorded approximately $1.2 million, $1.1 million and $1.3 million respectively, of tax benefit for its other stock-based plans. For 2009, 2008 and 2007, the recognition of total stock-based compensation expense impacted both basic and diluted net income per common share by $0.08, $0.10 and $0.10, respectively.

Basic net income per common share is calculated by dividing net income by the weighted average number of common shares outstanding. The calculation of diluted income per share assumes the conversion of all dilutive securities (see Note 13).

Net income attributable to Watt's Water Technologies, Inc. and number of shares used to compute net income per share, basic and assuming full dilution, are reconciled below:

The computation of diluted net income per share for the years ended December 31, 2009, 2008 and 2007 excludes the effect of the potential exercise of options to purchase approximately 0.9 million, 1.0 million and 0.5 shares, respectively, because the exercise price of the option was greater than the average market price of the Class A Common Stock, as the effect would have been anti-dilutive.

During the years ended December 31, 2008 and 2007, the Company repurchased approximately 1.6 million shares and 0.9 million shares, respectively, of its Class A Common Stock.

In the normal course of business, the Company manages risks associated with commodity prices, foreign exchange rates and interest rates through a variety of strategies, including the use of hedging transactions, executed in accordance with the Company's policies. The Company's hedging transactions include, but are not limited to, the use of various derivative financial and commodity instruments. As a matter of policy, the Company does not use derivative instruments unless there is an underlying exposure. Any change in value of the derivative instruments would be substantially offset by an opposite change in the value of the underlying hedged items. The Company does not use derivative instruments for trading or speculative purposes.

Derivative instruments may be designated and accounted for as either a hedge of a recognized asset or liability (fair value hedge) or a hedge of a forecasted transaction (cash flow hedge). For a fair value hedge, both the effective and ineffective portions of the change in fair value of the derivative instrument, along with an adjustment to the carrying amount of the hedged item for fair value changes attributable to the hedged risk, are recognized in earnings. For a cash flow hedge, changes in the fair value of the derivative instrument that are highly effective are deferred in accumulated other comprehensive income or loss until the underlying hedged item is recognized in earnings.

If a fair value or cash flow hedge were to cease to qualify for hedge accounting or be terminated, it would continue to be carried on the balance sheet at fair value until settled, but hedge accounting would be discontinued prospectively. If a forecasted transaction was no longer probable of occurring, amounts previously deferred in accumulated other comprehensive income would be recognized immediately in earnings. On occasion, the Company may enter into a derivative instrument that does not qualify for hedge accounting because it is entered into to offset changes in the fair value of an underlying transaction which is required to be recognized in earnings (natural hedge). These instruments are reflected in the Consolidated Balance Sheets at fair value with changes in fair value recognized in earnings.

Foreign currency derivatives include forward foreign exchange contracts primarily for Canadian dollars. Metal derivatives included commodity swaps for copper. During 2009 and 2008, the Company used a copper swap as a means of hedging exposure to metal prices (see Note 16).

Portions of the Company's outstanding debt are exposed to interest rate risks. The Company monitors its interest rate exposures on an ongoing basis to maximize the overall effectiveness of its interest rates.

Shipping and handling costs included in selling, general and administrative expense amounted to $31.4 million, $39.4 million and $38.9 million for the years ended December 31, 2009, 2008 and 2007, respectively.

Research and development costs included in selling, general, and administrative expense amounted to $17.8 million, $17.5 million and $15.1 million for the years ended December 31, 2009, 2008 and 2007, respectively.

The Company recognizes revenue when all of the following criteria have been met: the Company has entered into a binding agreement, the product has been shipped and title passes, the sales price to the customer is fixed or is determinable, and collectability is reasonably assured. Provisions for estimated returns and allowances are made at the time of sale, and are recorded as a reduction of sales and included in the allowance for doubtful accounts in the Consolidated Balance Sheets. The Company records provisions for sales incentives (primarily volume rebates), as an adjustment to net sales, at the time of sale based on estimated purchase targets.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

fiscal years. The Company is evaluating the impact that this update will have but does not expect the adoption to have a material impact on its consolidated financial statements.

In October 2009, the FASB issued an accounting standard update to address accounting for multiple-deliverable arrangements, specifically addressing how to separate deliverables and how to measure and allocate arrangement consideration to one or more units of accounting. This update established a hierarchy for determining the selling price of a deliverable. This standard also expands disclosures relating to an entity's multiple-deliverable revenue arrangements. This update is effective prospectively for all arrangements entered into or materially modified in fiscal years beginning after June 15, 2010. The adoption of this update is not expected to have a material impact on the Company's consolidated financial statements.

In June 2009, the FASB issued a new standard which identifies the sources of accounting principles and the framework for selecting the principles used in the preparation of financial statements that are presented in conformity with Generally Accepted Accounting Principles (GAAP) in the United States (the GAAP hierarchy). This standard also establishes the FASB Accounting Standards Codification (ASC) as the source of authoritative accounting principles recognized by the FASB to be applied in the preparation of non-governmental financial statements. This standard is effective for all interim and annual financial statements issued after September 15, 2009. The adoption of this standard did not have a material impact on the Company's consolidated financial statements.

In June 2009, the FASB issued a new standard which requires an entity to perform an analysis to determine whether the variable interest or interests give it a controlling financial interest. This statement also requires an entity to regularly reassess whether the entity has a controlling financial interest in the variable interest or interests. This statement will also expand disclosures on variable interest or interests in the footnotes. This standard is effective for the first annual reporting period beginning after November 15, 2009 as well as the interim period therein. The adoption of this standard did not have a material impact on the Company's consolidated financial statements.

In June 2009, the FASB issued a new standard which eliminates the concept of a qualifying special-purpose entity as defined in other GAAP literature. This statement also establishes more stringent conditions for reporting a transfer of a portion of a financial asset as a sale and changes the initial measurement of a transferor's interest in transferred financial assets. This statement expands disclosures for interim and annual reports and is effective for the first annual reporting period beginning after November 15, 2009. The adoption of this standard did not have a material impact on the Company's consolidated financial statements.

In September 2009, the Company's Board of Directors approved the sale of its investment in CWV. CWV is a manufacturer of large diameter hydraulic-actuated butterfly valves for thermo-power and hydro-power plants, water distribution projects and water works projects in China. Management determined that CWV's business no longer fit strategically with the Company. The Company completed the sale of CWV in January 2010. See Note 5 for further information related to CWV.

The Company evaluated the classification of the assets and liabilities of CWV and concluded that the net assets qualified as discontinued operations. The Company evaluated the fair value less cost to sell of the net assets of CWV and recorded an estimated pre-tax non-cash loss of approximately $8.5 million based on the final agreement with the buyer (level 1). The Company concluded that the future cash flows associated with CWV will be completely eliminated from the continuing operations of

the Company. As such, the Company classified CWV's result of operations and the loss from the disposition as discontinued operations for all periods presented.

In May 2009, the Company liquidated its TEAM business, located in Ammanford, U.K. TEAM custom designed and manufactured manipulated pipe and hose tubing assemblies and served the heating, ventilation and air conditioning and automotive markets in Western Europe. Management determined the business no longer fit strategically with the Company and that a sale of TEAM was not feasible. On May 22, 2009, the Company appointed an administrator for TEAM under the United Kingdom Insolvency Act of 1986. During the administration process, the administrator has sole control over, and responsibility for, TEAM's operations, assets and liabilities. The Company deconsolidated TEAM when the administrator obtained control of TEAM. The deconsolidation resulted in the recognition of a $18.0 million pre-tax non-cash loss in 2009. The Company evaluated the operations of TEAM and determined that it will not have a continuing involvement in TEAM's operations and cash flows. As a result of the loss of control, TEAM's cash flows and operations have been eliminated from the continuing operations of the Company. As such, the Company has classified TEAM's results of operations and the loss from deconsolidation as discontinued operations for all periods presented.

In September 1996, the Company divested its Municipal Water Group businesses, which included Henry Pratt, James Jones Company and Edward Barber and Company Ltd. The discontinued operating expense for 2009 and 2008 are related to the operations and write-off of TEAM, operations and estimated loss on the net assets of CWV and legal costs, net of reserve adjustments, associated with the James Jones Litigation (see Note 15).

Condensed operating statements for discontinued operations are summarized below:

The Company did not recognize any tax benefits on the write down of net assets of CWV as the Company does not believe that it is more likely than not that the tax benefits would be realized.

The carrying amounts of major classes of assets and liabilities at December 31, 2009 and December 31, 2008 associated with discontinued operations are as follows:

The Company's Board of Directors approves all major restructuring programs that involve the discontinuance of product lines or the shut down of facilities. From time to time, the Company takes additional restructuring actions including involuntary terminations that are not part of a major program. The Company accounts for these costs in the period that the individual employees are notified or the liability is incurred. These costs are included in restructuring and other charges in the

Company's consolidated statements of operations. The Company also includes as part of other charges costs associated with asset impairments. A summary of the cost by restructuring program is as follows:

The Company recorded net pre-tax restructuring and other charges in its business segments as follows:

For 2009, pre-tax costs of $1.7 million recorded in costs of goods sold were primarily for accelerated depreciation. Net pre-tax costs of $16.1 million recorded in restructuring and other charges included $8.0 million in severance costs and $9.2 million in other charges, principally $8.4 million in impairment charges for certain long-lived assets and $0.8 million of relocation costs associated with the 2009 actions described below, offset by a $1.1 million gain from the disposition of Tianjin Tanggu Watts Valve Co. Ltd. (TWT). The TWT gain was deferred from the year ended December 31, 2008 until local government approvals were finalized. Of the $8.0 million in severance costs, approximately $1.6 million relates to involuntary termination benefits incurred during 2009 which were not part of a previously announced restructuring plan, $4.2 million were associated with the 2010 actions described below, $1.7 million were associated with the 2009 actions described below and $0.5 million related primarily to involuntary termination benefits and relocation expenses associated with the 2007 actions described below.

Also, during 2009, the Company recorded a tax charge of $3.9 million related to previously realized tax benefits in China, which the Company expects will be recaptured as a result of the Company's decision to restructure its operations in 2009. This tax charge is part of the 2009 actions.

For 2008, pre-tax costs of $0.3 million recorded in costs of goods sold were primarily for accelerated depreciation. Pre-tax costs of $5.6 million recorded in restructuring and other charges were primarily severance costs, asset write-downs, accelerated depreciation related to the Company's

relocation of its then 60% owned Chinese joint venture. Of the $5.6 million in restructuring costs, approximately $2.2 million relates to involuntary termination benefits incurred during 2008 which were not part of a previously announced restructuring plan and $3.4 million related primarily to involuntary termination benefits and relocation expenses associated with the 2007 actions described below. The Company also recognized income of $0.2 million in non-controlling interest representing the 40% liability of its then Chinese joint venture partner in the restructuring plan.

For 2007, the Company recorded pre-tax charges of approximately $7.5 million. Pre-tax costs of $4.3 million recorded in costs of goods sold were primarily for product line discontinuances, of which $1.2 million relates to product line discontinuances and accelerated depreciation related to the Company's relocation of its then 60% owned Chinese joint venture which were not part of a previously announced restructuring plan. Pre-tax costs of $3.2 million recorded in restructuring and other charges consisted of $2.0 million for asset write-downs and severance costs in both China and North America and $1.2 million of accelerated depreciation related to the Company's relocation of its then 60% owned Chinese joint venture which was not part of a previously announced restructuring plan. The Company also recognized income of $0.9 million in minority interest representing the 40% liability of its then Chinese joint venture partners in the restructuring plan.

During 2007, the Company undertook a review of certain product lines and its overall manufacturing capacity. Based on that review, the Company initiated a global restructuring program that was approved by the Company's Board of Directors on October 30, 2007. The Company also discontinued certain product lines. This program included the shutdown of several manufacturing facilities and the right-sizing of another facility. The restructuring program and charges for certain product line discontinuances was expected to include pre-tax charges totaling approximately $12.9 million. Charges were primarily for asset write-downs and expected net losses on asset disposals, severance costs and facility exit and other costs. Annual cash savings, net of tax, are estimated to be $1.1 million, which are expected to be fully realized by 2010.

The Company reviewed the remaining activities associated with the 2007 actions associated with Europe. Due in large part to this review, the Company has concluded that no further charges will be incurred under this program. In February 2010, the Company's Board of Directors approved a new program for Europe to be launched in 2010 that will include some of the components identified in the 2007 actions. The following table presents the total pre-tax charges incurred for the global restructuring program and product line discontinuances initiated in 2007 by the Company's reportable segments:

North America incurred restructuring costs in excess of the planned amount primarily due to the write-down of a vacated facility to its estimated fair value. As part of the 2007 plan, the Company

closed one facility and consolidated the operations into an existing facility. The plan, when created, called for the sale of the building once vacated. The plan did not anticipate the significant downturn in the commercial real estate market, which occurred shortly after the consolidation was completed in 2008. As a result of the continued poor commercial real estate market conditions, in 2009 the Company recorded a reduction in the carrying cost of the building to its estimated fair value, less the estimated costs to sell, of $2.3 million. The remaining excess was primarily as a result of higher costs incurred to complete the consolidation of the two facilities than originally anticipated.

The following table summarizes incurred cost for 2007 restructuring actions by segment:

Details of the Company's 2007 restructuring actions through December 31, 2009 are as follows:

The following table summarizes the incurred cost for 2007 restructuring actions by type:

In 2008, the Company announced a reduction-in-force in its United States workforce. The severance charge of $2.2 million, recorded in 2008, was included in restructuring and other charges related to its North America segment and was substantially spent by the end of 2008.

On February 8, 2009, the Board of Directors approved a plan to expand the Company's program to consolidate its manufacturing footprint in North America and China. The plan provides for the closure of three additional plants, with those operations being moved to existing facilities in either North America or China or relocated to a new central facility in the United States.

The footprint consolidation pre-tax charge was estimated at approximately $11.7 million, including severance charges of approximately $3.2 million, relocation costs of approximately $3.3 million and asset write-downs of approximately $5.2 million. One-time tax charges of approximately $3.9 million were incurred as part of the relocations. The Company may incur an additional one-time tax charge in connection with the restructuring activities that could range from $0 to $4.4 million, depending on the Company's final plans. Approximately 400 positions could be eliminated by this program. The net after-tax charge for this manufacturing consolidation program is expected to range from $12.8 to $17.2 million ($4.4 million non cash), with costs being incurred in fiscal 2009 and 2010. The Company expects to spend approximately $4.8 million in capital expenditures to consolidate operations.

The Company is still evaluating the remaining plant consolidations originally anticipated with the 2009 actions. The original plan called for the closure and relocation of the manufacturing activities associated with two facilities located in China. The Company has substantially completed the closure and relocation of one of the facilities during 2009. Throughout 2009, the other facility identified in the plan that was to be closed has improved its operations substantially. Due to this improvement, the Company is evaluating if the closure and relocation of the manufacturing activities for this location is still an appropriate action to take. The Company expects to conclude on the additional actions in 2010.

The following table summarizes the total estimated pre-tax charges expected, incurred and remaining cost for the footprint consolidation-restructuring program initiated in 2009 by the Company's reportable segments:

Details of the Company's footprint consolidation-restructuring program through December 31, 2009 are as follows:

On February 8, 2010, the Board of Directors approved a restructuring program with respect to the Company's operating facilities in France. The restructuring program is expected to include the shutdown of three facilities, including two manufacturing sites and one distribution center. The program is expected to include pre-tax charges totaling approximately $12.5 million, including costs for severance, relocation, clean-up and certain asset write-downs, and result in the elimination of approximately 95 positions. Total net after-tax charges for this restructuring program are expected to be approximately $8.3 million ($1.1 million in non-cash charges), with costs being incurred through 2011. The Company expects to spend approximately $6.6 million in capital expenditures to consolidate operations. Annual cash savings, net of tax, are estimated to be $3.9 million, which the Company expects to fully realize by 2012. The Company recorded certain severance costs related to this program in 2009 as the amounts related to contractual or statutory obligations.

Details of the Company's footprint consolidation-restructuring program through December 31, 2009 are as follows:

On May 30, 2008, the Company acquired all of the outstanding stock of Blücher Metal A/S (Blücher) for approximately $183.5 million. The purchase price consisted of $170.1 million in cash and the assumption of debt of $13.4 million, net of cash acquired. Blücher is a leading provider of stainless steel drainage systems in Europe to the residential, commercial and industrial market places and is a worldwide leader in providing stainless steel drainage products to the marine industry. Blücher provides

the Company with a new product platform in Europe while allowing the Company to offer a broader product line to its existing customer base. The Company completed a purchase price allocation that resulted in the recognition of $64.5 million in intangible assets and $89.5 million in goodwill. Intangible assets are comprised primarily of customer relationships and patents with estimated lives of 10 years and trade names with indefinite lives. The consolidated results of operations include the results of Blücher since the acquisition date of May 30, 2008.

During the second quarter of 2008, the Company completed the acquisition of the remaining 40% ownership of its joint venture in China, TWT, for $3.3 million in cash. TWT manufactured products to support the U.S. operations as well as to sell into the local China market. In the third quarter of 2008, the Company relocated the business supporting the U.S. from TWT into an existing operation in China. The Company then entered into an agreement to sell TWT. Under this agreement, the Company determined that the risks and rewards of ownership of TWT were effectively transferred to the buyer as of October 18, 2008. The Company further determined that it was no longer the primary beneficiary of the operating results of TWT and therefore deconsolidated TWT as of October 18, 2008. The Company recognized a $1.1 million gain from the sale in 2009 upon the final approval of the transfer by Chinese government authority. See Note 3 for additional information concerning dispositions.

Certain acquisition agreements from prior years contain earn-out provisions. In 2009, 2008 and 2007, the Company accrued approximately $0.5 million, $0.4 million and $3.8 million, respectively, for earn-out provisions which were charged to goodwill and were paid in the year following each earn-out. The calculations are typically based on a multiple of future gross margins or operating earnings as defined in the agreements.

Finished goods of $13.8 million and $19.1 million as of December 31, 2009 and 2008, respectively, were consigned.

The significant components of the Company's deferred income tax liabilities and assets are as follows:

			December 31,

			2009			2008
			(in millions)
Deferred income tax liabilities:
	Excess tax over book depreciation		$	16.4		$	15.8
	Intangibles			30.5			31.4
	Other			9.5			8.5

		Total deferred tax liabilities		56.4			55.7
Deferred income tax assets:
	Accrued expenses			21.6			23.9
	Net operating loss carry-forward			10.0			4.3
	Inventory reserves			6.3			10.3
	Other			23.7			28.6

		Total deferred tax assets		61.6			67.1
Less: valuation allowance				(9.8	)		(4.7	)

	Net deferred tax assets			51.8			62.4

	Net deferred tax assets (liabilities)		$	(4.6	)	$	6.7

The provision for income taxes from continuing operations is based on the following pre-tax income:

The provision for income taxes from continuing operations consists of the following:

Actual income taxes reported from continuing operations are different than would have been computed by applying the federal statutory tax rate to income from continuing operations before income taxes. The reasons for this difference are as follows:

At December 31, 2009, the Company has foreign net operating loss carry forwards of $38.9 million for income tax purposes; $5.6 million of the losses can be carried forward indefinitely, $6.9 million of the losses expire in 2014, $5.0 million expire in 2016, $5.1 million expire in 2017, and $16.3 million expire in 2018. The net operating losses consist of $5.5 million related to German operations, $0.1 million to Austrian operations, $26.4 million to Dutch operations, and $6.9 related to Chinese operations.

At December 31, 2009, the Company had a valuation allowance of $9.8 million. In the U.S., $4.6 million relates to a capital loss as management believes it is not more likely than not that the Company would use such loss within the applicable carryforward period. In Europe, a valuation allowance of $3.0 million pertains to a net operating loss in our Dutch operations. In China, a valuation allowance of $2.2 million relates to TWVC's deferred tax assets that the Company believes will not be utilized. The entire $4.7 million beginning of year valuation allowance pertained to the U.S. capital loss. The Company does not have a valuation allowance on other deferred tax assets, as management believes that it is more likely than not that the Company will recover the net deferred tax assets.

Enacted changes in income tax laws did not have a material effect on the Company in 2009, 2008 or 2007.

Undistributed earnings of the Company's foreign subsidiaries amounted to approximately $320.3 million at December 31, 2009, $311.7 million at December 31, 2008, and $249.9 million at December 31, 2007. Those earnings are considered to be indefinitely reinvested and, accordingly, no provision for U.S. federal and state income taxes has been recorded thereon. Upon distribution of those earnings, in the form of dividends or otherwise, the Company will be subject to withholding taxes payable to the various foreign countries. Determination of the amount of U.S. income tax liability that would be incurred is not practicable because of the complexities associated with its hypothetical calculation; however, unrecognized foreign tax credits may be available to reduce some portion of any U.S. income tax liability. Withholding taxes of approximately $7.2 million would be payable upon remittance of all previously unremitted earnings at December 31, 2009.

Principal payments during each of the next five years and thereafter are due as follows (in millions): 2010—$50.9; 2011—$0.7; 2012—$0.7; 2013—$75.7; 2014—$0.8 and thereafter—$226.1.

The Company maintains letters of credit that guarantee its performance or payment to third parties in accordance with specified terms and conditions. Amounts outstanding were approximately $37.0 million as of December 31, 2009 and $39.3 million as of December 31, 2008. The Company's letters of credit are primarily associated with insurance coverage and to a lesser extent foreign purchases. The Company's letters of credit generally expire within one year of issuance and are drawn down against the revolving credit facility. These instruments may exist or expire without being drawn down. Therefore, they do not necessarily represent future cash flow obligations.

On April 27, 2006, the Company completed a private placement of $225.0 million of 5.85% senior unsecured notes due April 2016 (the 2006 Note Purchase Agreement). The 2006 Note Purchase Agreement includes operational and financial covenants, with which the Company is required to comply, including, among others, maintenance of certain financial ratios and restrictions on additional indebtedness, liens and dispositions. Events of default under the 2006 Note Purchase Agreement include failure to comply with its financial and operational covenants, as well as bankruptcy and other insolvency events. The Company may, at its option, upon notice to the noteholders, prepay at any time all or part of the Notes in an amount not less than $1.0 million by paying the principal amount plus a make-whole amount, which is dependent upon the yield of respective U.S. Treasury Securities. As of December 31, 2009, the Company was in compliance with all covenants related to the 2006 Note Purchase Agreement. The payment of interest on the senior unsecured notes is due semi-annually on April 30^th and October 30^th of each year. Additionally, the Company amended its 2003 Note Purchase Agreement to reflect the existence of the subsidiary guarantors and to substantially conform certain provisions of the 2003 Note Purchase Agreement to the 2006 Note Purchase Agreement.

On April 27, 2006, the Company amended and restated its unsecured revolving credit facility with a syndicate of banks (as amended, the revolving credit facility). The revolving credit facility provides for multi-currency unsecured borrowings and stand-by letters of credit of up to $350.0 million and expires in April 2011. Borrowings outstanding under the revolving credit facility bear interest at a fluctuating rate per annum equal to an applicable percentage equal to (i) in the case of Eurocurrency rate loans, the British Bankers Association LIBOR rate plus an applicable percentage of 0.625%, which is determined by reference to the Company's consolidated leverage ratio and debt rating, or (ii) in the case of base rate loans and swing line loans, the higher of (a) the federal funds rate plus 0.5% and (b) the rate of interest in effect for such day as announced by Bank of America, N.A. as its "prime rate." For 2009, the average interest rate under the revolving credit facility for euro-based borrowings was approximately 2.2%. The revolving credit facility includes operational and financial covenants customary for facilities of this type, including, among others, restrictions on additional indebtedness, liens and investments and maintenance of certain leverage ratios. As of December 31, 2009, the Company was in compliance with all covenants related to the revolving credit facility; the Company had $314.4 million of unused credit under the revolving credit facility and $35.6 million for stand-by letters of credit outstanding on its revolving credit facility. Due primarily to the current leverage ratio, the Company could borrow approximately $108.5 million under the existing facility, excluding the stand-by-letters of credit, before it would violate the above covenants.

On May 15, 2003, the Company completed a private placement of $125.0 million of senior unsecured notes consisting of $50.0 million principal amount of 4.87% senior notes due 2010 and $75.0 million principal amount of 5.47% senior notes due 2013. The payment of interest on the senior unsecured notes is due semi-annually on May 15th and November 15th of each year. The senior unsecured notes were issued by Watts Water Technologies, Inc. and are pari passu with the revolving credit facility. The senior unsecured notes allow the Company to have (i) debt senior to the notes in an amount up to $150.0 million plus 5% of stockholders' equity and (ii) debt pari passu or junior to the senior unsecured notes to the extent the Company maintains compliance with a 2.0 to 1.0 fixed charge coverage ratio. The notes include a prepayment provision which might require a make-whole payment to the note holders. Such payment is dependent upon the level of the respective treasuries. The notes include other customary terms and conditions, including events of default.

The Class A Common Stock and Class B Common Stock have equal dividend and liquidation rights. Each share of the Company's Class A Common Stock is entitled to one vote on all matters submitted to stockholders and each share of Class B Common Stock is entitled to ten votes on all such matters. Shares of Class B Common Stock are convertible into shares of Class A Common Stock, on a one-to-one basis, at the option of the holder. As of December 31, 2009, the Company has reserved a total of 4,078,905 of Class A Common Stock for issuance under its stock-based compensation plans and 7,193,880 shares for conversion of Class B Common Stock to Class A Common Stock.

In November 2007, the Company announced that its Board of Directors had authorized a repurchase of up to 3,000,000 shares of its Class A Common Stock. As of December 31, 2009, the Company had repurchased 2.45 million shares of stock for a total cost of $68.1 million.

The Company maintains three stock incentive plans under which key employees and outside directors have been granted incentive stock options (ISOs) and nonqualified stock options (NSOs) to

purchase the Company's Class A Common Stock. Only one plan, the 2004 Stock Incentive Plan, is currently available for the grant of new equity awards. Stock options granted under prior plans became exercisable over a five-year period at the rate of 20% per year and expire ten years after the date of grant. Under the 2004 Stock Incentive Plan, options become exercisable over a four-year period at the rate of 25% per year and expire ten years after the grant date. ISOs and NSOs granted under the plans may have exercise prices of not less than 100% and 50% of the fair market value of the Class A Common Stock on the date of grant, respectively. The Company's current practice is to grant all options at fair market value on the grant date. At December 31, 2009, 2,428,706 shares of Class A Common Stock were authorized for future grants of new equity awards under the Company's stock incentive plans.

The Company also grants shares of restricted stock to key employees and non-employee members of the Company's Board of Directors under the 2004 Stock Incentive Plan, which vest either immediately or over a three-year period at the rate of one-third per year. The restricted stock awards are amortized to expense on a straight-line basis over the vesting period.

The Company also has a Management Stock Purchase Plan that allows for the granting of restricted stock units (RSUs) to key employees. On an annual basis, key employees may elect to receive a portion of their annual incentive compensation in RSUs instead of cash. Each RSU provides the key employee with the right to purchase a share of Class A Common Stock at 67% of the fair market value on the date of grant. RSUs vest annually over a three-year period from the grant date. An aggregate of 2,000,000 shares of Class A Common Stock may be issued under the Management Stock Purchase Plan.

At December 31, 2009, total unrecognized compensation cost related to the unvested stock options was approximately $3.9 million with a total weighted average remaining term of 2.8 years. For 2009, 2008 and 2007, the Company recognized compensation cost of $1.7 million, $2.3 million and $2.7 million, respectively, in selling, general and administrative expenses.

As of December 31, 2009, the aggregate intrinsic values of exercisable options were approximately $5.2 million, representing the total pre-tax intrinsic value, based on the Company's closing Class A Common Stock price of $30.92 as of December 31, 2009, which would have been received by the

option holders had all option holders exercised their options as of that date. The total intrinsic value of options exercised for 2009, 2008 and 2007 was approximately $0.3 million, $0.8 million and $1.4 million, respectively.

The following table summarizes information about options outstanding at December 31, 2009:

The fair value of each option granted under the 2004 Stock Incentive Plan is estimated on the date of grant, using the Black-Scholes-Merton Model, based on the following weighted average assumptions:

The risk-free interest rate is based upon the U.S. Treasury yield curve at the time of grant for the respective expected life of the option. The expected life (estimated period of time outstanding) of options and volatility were calculated using historical data. The expected dividend yield of stock is the Company's best estimate of the expected future dividend yield. The Company applied an estimated forfeiture rate of 6.75% for 2009 for its stock options. These rates were calculated based upon historical activity and are an estimate of granted shares not expected to vest. If actual forfeitures differ from the expected rates, the Company may be required to make additional adjustments to compensation expense in future periods.

The above assumptions were used to determine the weighted average grant-date fair value of stock options of $9.70, $10.10 and $12.75 for the years ending December 31, 2009, 2008 and 2007, respectively.

The following is a summary of unvested restricted stock activity and related information:

The total fair value of shares vested during 2009, 2008 and 2007 was $2.1 million, $1.4 million and $1.4 million, respectively. At December 31, 2009, total unrecognized compensation cost related to unvested restricted stock was approximately $2.6 million with a total weighted average remaining term of 2.0 years. For 2009, 2008 and 2007, the Company recognized compensation costs of $2.0 million, $1.8 million and $1.6 million, respectively, in selling, general and administrative expenses. The Company applied an estimated forfeiture rate of 5.2% for restricted stock issued to key employees. The aggregate intrinsic value of restricted stock granted and outstanding approximated $3.6 million representing the total pre-tax intrinsic value based on the Company's closing Class A Common Stock price of $30.92 as of December 31, 2009.

Total unrecognized compensation cost related to unvested RSUs was approximately $1.2 million at December 31, 2009 with a total weighted average remaining term of 1.8 years. For 2009, 2008 and 2007 the Company recognized compensation cost of $1.2 million, $1.2 million and $1.7 million, respectively, in selling, general and administrative expenses. Dividends declared for RSUs, that are paid to individuals, that remain unpaid at December 31, 2009 total approximately $0.2 million.

A summary of the Company's RSU activity and related information for 2009 is shown in the following table:

As of December 31, 2009, the aggregate intrinsic values of outstanding and vested RSUs were approximately $4.5 million and $1.3 million, respectively, representing the total pre-tax intrinsic value, based on the Company's closing Class A Common Stock price of $30.92 as of December 31, 2009 which would have been received by the RSUs holders had all RSUs settled as of that date. The total intrinsic value of RSUs settled for 2009, 2008 and 2007 was approximately $0.1 million, $0.7 million and $2.5 million, respectively. Upon settlement of RSUs, the Company issues shares of Class A Common Stock.

The following table summarizes information about RSUs outstanding at December 31, 2009:

The fair value of each share issued under the Management Stock Purchase Plan is estimated on the date of grant, using the Black-Scholes-Merton Model, based on the following weighted average assumptions:

The risk-free interest rate is based upon the U.S. Treasury yield curve at the time of grant for the respective expected life of the RSU's. The expected life (estimated period of time outstanding) of RSU's and volatility were calculated using historical data. The expected dividend yield of stock is the Company's best estimate of the expected future dividend yield. The Company applied an estimated forfeiture rate of 5.2% for its RSUs. These rates were calculated based upon historical activity and are an estimate of granted shares not expected to vest. If actual forfeitures differ from the expected rates, the Company may be required to make additional adjustments to compensation expense in future periods.

The above assumptions were used to determine the weighted average grant-date fair value of RSUs granted of $8.14, $11.44 and $16.79 during 2009, 2008 and 2007, respectively.

The Company distributed dividends of $0.44 per share for 2009, $0.44 per share for 2008 and $0.40 per share for 2007 on the Company's Class A Common Stock and Class B Common Stock.

The Company sponsors funded and unfunded non-contributing defined benefit pension plans that together cover substantially all of its domestic employees. Benefits are based primarily on years of service and employees' compensation. The funding policy of the Company for these plans is to contribute an annual amount that does not exceed the maximum amount that can be deducted for federal income tax purposes.

The funded status of the defined benefit plans and amounts recognized in the consolidated balance sheet are as follows:

		December 31,

		2009			2008

Information for pension plans with an accumulated benefit obligation in excess of plan assets are as follows:

The estimated net actuarial loss and prior service cost for the defined benefit pension plans that will be amortized from accumulated other comprehensive income into net periodic benefit cost over the next year are $2.3 million and $0.3 million, respectively.

Discount rates are selected based upon rates of return at the measurement date utilizing a bond matching approach to match the expected benefit cash flows. In selecting the expected long-term rate of return on assets, the Company considers the average rate of earnings expected on the funds invested or to be invested to provide for the benefits of this plan. This includes considering the trust's asset allocation and the expected returns likely to be earned over the life of the plan. This basis is consistent with the prior year.

The Company's written Retirement Plan Investment Policy sets forth the investment policy, objectives and constraints of the Watts Water Technologies, Inc. Pension Plan. This Retirement Plan Investment Policy, set forth by the Pension Plan Committee, defines general investment principles and directs investment management policy, addressing preservation of capital, risk aversion and adherence to investment discipline. Investment managers are to make a reasonable effort to control risk and are evaluated quarterly against commonly accepted benchmarks to ensure that the risk assumed is commensurate with the given investment style and objectives.

The portfolio is designed to achieve a balanced return of current income and modest growth of capital, while achieving returns in excess of the rate of inflation over the investment horizon in order to preserve purchasing power of Plan assets. All Plan assets are required to be invested in liquid securities. Derivative investments are not allowed.

Prohibited investments include, but are not limited to the following: commodities and futures contracts, private placements, options, limited partnerships, venture-capital investments, real estate properties, interest-only (IO), principal-only (PO), and residual tranche CMOs, and Watts Water Technologies, Inc. stock.

Prohibited transactions include, but are not limited to the following: short selling and margin transactions.

Allowable assets include: cash equivalents, fixed income securities, equity securities, mutual funds, and GICs.

Specific guidelines regarding allocation of assets are as follows: equities shall comprise between 25% and 75% of the total portfolio, while fixed income shall comprise between 30% and 65%. Investment performance is monitored on a regular basis and investments are re-allocated to stay within specific guidelines. An equity/fixed income allocation of 55%/45% is preferred. The securities of any one company or government agency should not exceed 10% of the total fund, and no more than 20% of the total fund should be invested in any one industry. Individual treasury securities may represent 50% of the total fund, while the total allocation to treasury bonds and notes may represent up to 100% of the Plan's aggregate bond position.

The following table presents the investments in the pension plan measured at fair value at December 31, 2009:

Additionally, substantially all of the Company's domestic employees are eligible to participate in certain 401(k) savings plans. Under these plans, the Company matches a specified percentage of employee contributions, subject to certain limitations. The Company's match contributions (included in selling, general and administrative expense) for the year ended December 31, 2009 were $0.5 million,

and for the years ended December 31, 2008 and 2007 were $0.6 million in each year, respectively. Charges for European pension plans approximated $2.8 million, $3.3 million and $3.0 million for the years ended December 31, 2009, 2008 and 2007, respectively. These costs relate to plans administered by certain European subsidiaries, with benefits calculated according to government requirements and paid out to employees upon retirement or change of employment.

The Company entered into a Supplemental Compensation Agreement (the Agreement) with Timothy P. Horne on September 1, 1996. Per the Agreement, upon ceasing to be an employee of the Company, Mr. Horne must make himself available, as requested by the Board, to work a minimum of 300 but not more than 500 hours per year as a consultant in return for certain annual compensation as long as he is physically able to do so. If Mr. Horne complies with the consulting provisions of the agreement above, he shall receive supplemental compensation on an annual basis of $400,000 per year, subject to cost of living increases each year, in exchange for the services performed, as long as he is physically able to do so. In the event of physical disability, subsequent to commencing consulting services for the Company, Mr. Horne will continue to receive this payment annually. The payment for consulting services provided by Mr. Horne will be expensed as incurred by the Company. Mr. Horne retired effective December 31, 2002, and therefore the Supplemental Compensation period began on January 1, 2003. In accordance with GAAP, the Company accrues for the future post-retirement disability benefits over the period from January 1, 2003, to the time in which Mr. Horne becomes physically unable to perform his consulting services (the period in which the disability benefits are earned).

As has been previously disclosed, the Company was party to a lawsuit filed by Nora Armenta in California Superior Court against us, James Jones Company, Mueller Co. and Tyco International (the "Armenta case") and a separate lawsuit filed in California Superior Court on behalf of the City of Banning, California and 42 other cities and water districts in California against the Company, James Jones Company and Mueller Co. (the "City of Banning case"). At a mediation session held with the California Superior Court on June 9-10, 2009, the parties to the Armenta case and the City of Banning case agreed in principle to settle both cases. The agreement in principle was effective and binding only upon approval by the plaintiffs in the Armenta and City of Banning cases, and final approval of the settlement by the California Superior Court after a fairness hearing. An agreement in principle also was reached to settle the related insurance coverage cases Watts Industries, Inc. vs. Zurich American Insurance Company, et al., and Zurich American Insurance Company vs. Watts Industries, Inc., et al., pending in California Superior Court; and Zurich American Insurance Company vs. Watts Industries, Inc. and James Jones Company, pending in the United States District Court for the Northern District of Illinois, Eastern Division. The settlement of the insurance coverage cases was effective and binding upon approval of the settlement of the underlying Armenta case and City of Banning case as described above.

The settlement agreement was approved by the plaintiffs in both the Armenta and City of Banning cases and, at the fairness hearing held on November 5, 2009, the California Superior Court approved the settlement of the Armenta case and City of Banning case. There were no objectors to the settlement. Based on the contemporaneous final settlement of the underlying insurance coverage cases, the Company's contribution to the settlement was $15.3 million. As a result of the settlements, all lawsuits and all claims were dismissed. In addition, separate from the settlement, the Company paid its

outside counsel an additional $5.0 million for services rendered in connection with the above described litigation.

As a result of the settlement of the above described litigation, the Company recorded a non-cash, pre-tax gain in discontinued operations of approximately $9.5 million in the fourth quarter of 2009 to reduce previously recorded estimates of the loss and related fees to the amounts noted above.

In July 2009, the Company received information that employees of CWV, at that time an indirect wholly-owned subsidiary of the Company in China, made payments to employees of state-owned agencies. Such payments may violate the Foreign Corrupt Practices Act. The Company is conducting an investigation utilizing outside counsel and voluntarily disclosed this matter to the United States Department of Justice and the Securities and Exchange Commission. The Company cannot predict the outcome of this matter at this time or whether it will have a materially adverse impact on its financial condition or results of operations. The Company sold CWV in January 2010.

The Company has been named as a potentially responsible party with respect to a limited number of identified contaminated sites. The levels of contamination vary significantly from site to site as do the related levels of remediation efforts. Environmental liabilities are recorded based on the most probable cost, if known, or on the estimated minimum cost of remediation. The Company accrues estimated environmental liabilities based on assumptions, which are subject to a number of factors and uncertainties. Circumstances which can affect the reliability and precision of these estimates include identification of additional sites, environmental regulations, level of cleanup required, technologies available, number and financial condition of other contributors to remediation and the time period over which remediation may occur. The Company recognizes changes in estimates as new remediation requirements are defined or as new information becomes available.

Based on the facts currently known to the Company, it does not believe that the ultimate outcome of these matters will have a material adverse effect on its liquidity, financial condition or results of operations. Some of its environmental matters are inherently uncertain and there exists a possibility that we may ultimately incur losses from these matters in excess of the amount accrued. However, the Company cannot currently estimate the amount of any such additional losses.

The Company is defending approximately 105 lawsuits in different jurisdictions, with the greatest number filed in Mississippi and California state courts, alleging injury or death as a result of exposure to asbestos. The complaints in these cases typically name a large number of defendants and do not identify any particular Watts products as a source of asbestos exposure. To date, the Company has obtained a dismissal in every case before it has reached trial because discovery has failed to yield evidence of substantial exposure to any Watts products. Based on the facts currently known to the Company, it does not believe that the ultimate outcome of these claims will have a material adverse effect on its liquidity, financial condition or results of operations.

Other lawsuits and proceedings or claims, arising from the ordinary course of operations, are also pending or threatened against us. Based on the facts currently known to the Company, it does not believe that the ultimate outcome of these other litigation matters will have a material adverse effect on its liquidity, financial condition or results of operations.

The carrying amounts of cash and cash equivalents, short-term investments, trade receivables and trade payables approximate fair value because of the short maturity of these financial instruments.

The fair value of the Company's 4.87% senior notes due 2010, 5.47% senior notes due 2013 and 5.85% senior notes due 2016 is based on quoted market prices of similar notes (level 2). The fair value of the Company's variable rate debt approximates its carrying value. The carrying amount and the estimated fair market value of the Company's long-term debt, including the current portion, are as follows:

The Company measures certain financial assets and liabilities at fair value on a recurring basis, including auction rate securities, foreign currency derivatives, deferred compensation plan assets and related liability, and metal derivatives. The fair value of these certain financial assets and liabilities was determined using the following inputs at December 31, 2009:

The table below provides a summary of the changes in fair value of all financial assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the period December 31, 2008 to December 31, 2009.

Trading securities comprise auction rate securities and rights issued by UBS. The Company holds a variety of interest bearing auction rate securities, or ARS, including $4.7 million in municipal bonds and $0.7 million in student loans at December 31, 2009. These ARS investments are intended to provide liquidity via an auction process that resets the applicable interest rate at predetermined calendar intervals, allowing investors to either roll over their holdings or sell their interests at par. The uncertainties in the credit markets have affected all of the Company's holdings in ARS investments, and auctions for the Company's investments in these securities have failed on their respective auction dates. Consequently, the investments are not currently liquid and the Company will not be able to access these funds until a future auction of these investments is successful or a buyer is found outside of the auction process. Maturity dates for these ARS investments range from 2027 to 2036.

During the fourth quarter of 2008, the Company elected to participate in a settlement offer from UBS for all of the outstanding ARS investments. Under the terms of the settlement offer, the Company was issued rights by UBS entitling the holder to require UBS to purchase the underlying ARS at par value during the period from June 30, 2010, through July 2, 2012. The rights, valued at $1.1 million at December 31, 2009, also entitle UBS to purchase or find a buyer for the ARS at any time at par value.

While the Company continues to earn interest on its ARS investments, these investments are not currently trading and therefore do not currently have a readily determinable market value.

The Company used a discounted cash flow model to determine the estimated fair value of its investment in ARS and investments in UBS rights as of December 31, 2009. The assumptions used in preparing the discounted cash flow model include estimates for interest rates, credit quality of the ARS issuer, timing and amount of cash flows, government guarantees related to student loans and the expected holding periods of the ARS. Based on this assessment of fair value, the Company recorded income of approximately $0.4 million to other income in the consolidated statement of operations for its investment in ARS in 2009. To determine the fair value of the rights issued by UBS in connection with the settlement, the Company used a discounted cash flow model for the period up to the first date which the Company can exercise the rights. Based on this assessment of fair value, the Company recorded a charge of approximately $0.5 million to other expense in 2009.

The Company used financial instruments to enhance its ability to manage risk, including foreign currency and commodity pricing exposures, which exist as part of its ongoing business operations. The

use of derivatives exposes the Company to counterparty credit risk for nonperformance and to market risk related to changes in currency exchange rates and commodity prices. The Company manages its exposure to counterparty credit risk through diversification of counterparties. The Company's counterparties in derivative transactions are substantial commercial banks with significant experience using such derivative instruments. The impact of market risk on the fair value and cash flows of the Company's derivative instruments is monitored and the Company restricts the use of derivative financial instruments to hedging activities. The Company does not enter into contracts for trading purposes nor does the Company enter into any contracts for speculative purposes. The use of derivative instruments is approved by senior management under written guidelines.

The Company has exposure to a number of foreign currency rates, including the Canadian Dollar, the Euro, the Chinese Yuan and the British Pound. To manage this risk, the Company generally uses a layering methodology whereby at the end of any quarter, the Company has generally entered into forward exchange contracts which hedge approximately 50% of the projected intercompany purchase transactions for the next twelve months. The Company primarily uses this strategy for the purchases between Canada and the U.S. The average volume of contracts can vary but generally approximates $10 to $12 million in open contracts at the end of any given quarter. At December 31, 2009, the Company had contracts for notional amounts aggregating approximately $9.0 million to buy various currencies. The Company accounts for the forward exchange contracts as an economic hedge. Realized and unrealized gains and losses on the contracts are recognized in other (income) expense in the consolidated statement of operations. These contracts do not subject the Company to significant market risk from exchange movement because they offset gains and losses on the related foreign currency denominated transactions.

In 2008, the Company entered into a series of copper swaps to fix the price per pound for copper from October 2008 through September 2009 for 1 million pounds to be delivered over 12 months for one customer. The Company determined that these copper swaps did not qualify for hedge accounting and accounted for these financial instruments as an economic hedge. Therefore, any changes in the fair value of the copper swaps were recorded immediately in the consolidated statement of operations. The Company does not enter into swap or forward contracts for speculative purposes. As of December 31, 2009, the Company had no outstanding swaps.

The following table discloses the fair values of derivative instruments on the Company's balance sheet as of December 31, 2009 and 2008:

The following table discloses the impact of derivative instruments on the Company's operations for 2009, 2008 and 2007:

The Company leases certain manufacturing facilities, sales offices, warehouses, and equipment. Generally, the leases carry renewal provisions and require the Company to pay maintenance costs. Future minimum lease payments under capital leases and non-cancelable operating leases as of December 31, 2008 are as follows:

The Company operates in three geographic segments: North America, Europe, and China. Each of these segments sell similar products, is managed separately and has separate financial results that are reviewed by the Company's chief operating decision-maker. All intercompany sales transactions have been eliminated. Sales by region are based upon location of the entity recording the sale. The accounting policies for each segment are the same as those described in the summary of significant accounting policies (see Note 2).

The following is a summary of the Company's significant accounts and balances by segment, reconciled to its consolidated totals:
