Strength Through Innovation
Strength Through Innovation

WWatts Water Technologies is a world leader 

in the manufacture of innovative products 

to control the efficiency, safety and quality of water 
within residential, commercial and institutional ap-
plications. Our expertise in a wide variety of water 
technologies enables us to be a comprehensive 
supplier to the water industry. 

We are a “pure play” in this industry; water is our 
primary focus and has been for 137 years. Our 
products center around four key application areas, 
referred to as our strategic business platforms:  
Commercial & Residential Flow, Water Reuse & 
Drainage, HVAC & Gas, and Water Quality.

We offer solutions for water and energy conserva-
tion, comfort and control, and water quality and 
safety, and increasingly our products support the 
sustainability efforts of our customers and the green 
building industry. 

We are focused on three key strategies for creating 
shareholder value:

• Improving performance through continuous 

improvement and operational excellence
•  Growing our business through innovation,  
better meeting customer needs, and making  
key acquisitions

• Pursuing leverage points throughout our 

business

Please see our Letter to Shareholders for an ex-
panded discussion of these strategies.

While Watts Water Technologies is U.S. based, 
we have a strong global presence. In 2010, 44% of 
our sales occurred outside of the United States. 
Supporting our operations are more than 5,000 
associates worldwide who are key to 
our product development and 
improved efficiency.

To Our Shareholders

2010 was a challenging year for the 

global economy and our end 

markets. Commercial and residential construction 
markets were at historic low levels. We also faced 
volatile commodity markets, with some commodi-
ties reaching record high price levels, and signifi-
cant foreign exchange rate fluctuations. But despite 
this difficult environment, our Company performed 
well and we improved our already strong financial 
condition.
In 2010, we took additional steps to strengthen 
our foundation, focusing on continuous improve-
ment and operational excellence. We continued to 
launch new and innovative products to meet our 
customers’ needs, strengthened the power of our 
brands, and completed several key strategic acquisi-
tions. Together, this helped us further strengthen 
our financial health and improve our position for 
the future.

Strengthening Our Foundation
Strengthening Our Foundation

IIn 2010, we continued to drive operational excel-

lence and greater efficiencies through our Con-
tinuous Improvement Operating System (CIOS) 
and through strategic manufacturing footprint 
consolidations.

Continuous Improvement
Continuous Improvement

Our CIOS program was launched in 2009 to 
equip our associates with a standardized approach 
to continually improve business processes. CIOS 
was created and launched by our Global Manu-
facturing Council in North America, Europe, and 
Asia to improve operational and financial results, 
as well as to deliver significant improvements 
across key business metrics and enhance customer 
satisfaction.
 In 2010, our associates continued to develop their 
skills and expand their use of our CIOS tools to 
drive improved performance across all of our key 
customer-focused operating metrics, including safety, 
quality, delivery, productivity, and working capital.
Our CIOS program is enabling us to identify and 
pursue improvement opportunities using tools such 
as Lean Manufacturing and Six Sigma, resulting in 
a safer work environment, shorter product lead-
times, and improved quality. It is also enabling us 
to free up significant physical space, improve inven-
tory turns, and deliver significant productivity and 
cost savings at sites around the world. 

Examples of CIOS Success
Examples of CIOS Success

More efficient ways of working are being devel-
oped primarily by shop floor associates who are 
being empowered through our CIOS process to 
eliminate waste in process and material flow.
For example, in a number of facilities, cross-
functional teams have developed new assembly 
cells that link all the process steps for a specific 
product to achieve continuous 
flow, eliminate batch working 
and foster greater teamwork. Vi-
sual performance boards inform 
the cell employees of daily plans 
and provide feedback of perfor-
mance against targets identified 
to satisfy each customer.
Each facility has also devel-
oped site-specific improvements 
and, through the CIOS process, 
all are delivering measurable 
results:
North America: In Franklin, NH, improve-
ments in the manufacturing of our Under Sink 
Guardian (USG) thermostatic mixing valves have 
resulted in a 61% reduction in needed floor space, 
which allows us to use the freed space for new 
product manufacturing. We have also achieved 
a 98% reduction in the distance the material 
needs to travel, a 32% improvement in productiv-
ity, a 71% reduction in the amount of inventory 
required and a 99% reduction in manufacturing 
lead time.
Europe: In Plovdiv, Bulgaria, improvements in 
the assembly process for our line of FIMET tem-
perature and pressure gauges have delivered a 25% 
reduction in product cycle time, an 83% increase in 
productivity, a 99% reduction in inventory, an 85% 
reduction in the distance traveled by the mate-
rial, and an ongoing approach to eliminate quality 
problems at the root cause.

Asia: In Yuhuan, China, improvements in the 
assembly system for F15 flexible water connec-
tors have resulted in a 95% reduction in product 
lead time, an 82% improvement in productivity, a 
95% reduction in work-in-process inventory and a 
22% improvement in delivery against the customer 
demand schedule.
Overall, our CIOS process is enabling associates 
to deliver continuous improvement and aim for 
best-in-class performance at these facilities and at 
other Watts Water Technologies locations around 
the world. Specifically, we have seen a meaningful 
improvement in our plant safety, improvement in 
gross margins, more efficient use in working capital 
and, as mentioned earlier, improvement in our free 
cash flow conversion rate.

Consolidating Our Footprint
Consolidating Our Footprint

In 2010, we made further progress in consolidat-
ing our manufacturing footprint. We completed 
the consolidation of our PEX production and 
distribution operations into a new state-of-the-
art facility in Kansas City, MO. This new Center 
of Excellence for PEX manufacturing will 
improve our operating costs, while also reducing 
lead times and freight costs for our customers. 
We streamlined our North American distri-
bution network allowing us to close distribu-
tion centers in Vernon, CA; Chicago, IL; and 
Springfield, MO, reducing our logistics costs 
and improving our customer service.

Also in 2010, we completed the integration of 
several previously acquired companies within our 
Water Quality business platform into a single 
organization. This change allows for a more robust 
offering of both residential and commercial prod-
ucts and more focused operations dedicated to key 
strategic product lines. 
In Europe, we integrated BLÜCHER’s manu-
facturing and warehousing location in Vojens, 
Denmark, with its main facility in Vildbjerg, 
Denmark. This allows us to streamline operations 
and provide our customers with improved delivery 
times. We also integrated our Austrian and Ger-
man warehouses into a single distribution location 
in Landau, Germany.
In Asia, we completed the closure of our 
TWVC operations in Tianjin, China, and moved 
products both to our existing operation in 
Ningbo, China, and to our Franklin, NH, opera-
tion in the U.S.  
In 2010, we also announced two 
major projects that we plan to 
complete in 2011. We intend to 
cease manufacturing operations at 
our Regtrol plant in North Carolina 
and transition pieces of the opera-
tion to other locations. We also plan 
to complete the consolidation of our 
French manufacturing distribution 
footprint, reducing its operations 
from five to two locations.

North America 
Our Commercial & Residential Flow platform 
completed the rollout of a full line of lead free po-
table water products, required to meet new Califor-
nia and Vermont lead free standards. This positions 
us well to provide lead free products nationally, 
supporting the recently-enacted Reduction of Lead 
in Drinking Water Act, which will take effect in 
January 2014. 
Last year, we experienced continued volume growth 
in Watts potable PEX piping and accessories. We 
also launched 14 new products under the Watts and 
Powers brands that improve hot water system energy 
efficiency and safety, and we introduced a new gen-
eration of modular water pressure reducing valves. 
Our Water Reuse & Drainage platform acquired 
a new rainwater harvesting business, Blue Ridge 
Atlantic Enterprises (BRAE).  We also contin-
ued to broaden our new and very successful line 
of trench drains, including the Watts 6 inch wide 
Dead LevelTM Trench drain and the Watts 12 inch 
wide Dead LevelTM Trench drain. In addition, we 
incorporated BLÜCHER stainless steel drains 
into our product offerings in North America with 
promising results.
Our HVAC & Gas platform released a new Watts 
Radiant FlexPlate™ product line, graphite-based 
heat distribution panels for hydronic radiant appli-
cations, which significantly improve heat distribu-
tion over traditional aluminum plates. Also, we 

introduced our European MicroFlex® product line 
in North America and launched it as Watts Radi-
ant R-flex™ insulated PEX piping systems, which 
reduce heat loss and improve system efficiency. 
Also in 2010, our Water Quality platform con-
tinued to gain market share, offering 
environmentally friendly, low-salt and 
no-salt filtration and scale prevention 
products, and zero waste drinking 
water systems. Key among our Watts 
scale prevention products are the 
commercial OneFlow® and Sca-
leNet™ systems and the residential 
E-TREAT® system. These effective 
scale prevention technologies extend 
the life of plumbing systems and 
reduce energy costs by allowing heat 
to radiate more efficiently.
Our Instrumentation business 
showed solid double digit growth, 
with sales for HF Scientific up 19% 
in 2010. This growth is attributable 
to core market share capture, new 
market entry, new product releases 
and an expanding OEM business. In particular, 
two initiatives that gained significant traction 
in 2010 centered on ballast water monitoring to 
help prevent the spread of invasive aquatic species, 
and a push to develop a new family of safer and 
“greener” consumables for turbidity and chlorine 
monitoring.

Europe
In 2010, we increased market share in Europe 
with our new range of backflow products intro-
duced under our Commercial & Residential Flow
platform. This new range covers sizes up to and in-
cluding 2 inches, and the products were designed to 
reduce the weight of brass by 50% as compared to 
the previous models by incorporating several plastic 
components. Larger sizes are in the final design 
stages and are planned for launch in 2012.
As part of our HVAC & Gas platform, we 
continued to focus on renewable energy packages 
with a new range of integrated electronic controls. 
We also continued to gain market share with our 
insulated PEX piping product offering. This prod-
uct is well positioned as we address the increasing 
demands for energy efficiency, district heating and 
new heat loss standards in the European market.
Collaboration between two of our companies, 
Black Teknigas in the U.K. and Giuliani Anello 
in Italy, led to the development of new products 
providing gas control solutions. In 2010, the two 
companies collaborated on the modification of an 
existing gas shutoff valve for U.K. original equip-
ment manufacturers, as well as the modification of 
a leading Black Teknigas gas safety shutoff valve 
for the Italian market.
Within our Water Reuse & Drainage platform, 
we added new low-height floor drains to our line of 
BLÜCHER stainless steel drainage products to ad-
dress market demands for drains that fit into lighter 

building construction projects. These drains are de-
signed for low-height floors and decks in buildings 
and shower cabin applications on board ships. Our 
low-height drains are combinable with a variety of 
frames and gratings to suit any floor type and bath-
room style, and they further strengthen our leading 
position in the drains market.
Asia
During 2010, we established an 
engineering and advanced test 
center in Ningbo, China, to facili-
tate our growth strategies for Asia. 
Our goal is to leverage our North 
American and European capa-
bilities into Asia, develop advanced 
local expertise and expand our full 
product line, as well as provide low-
cost engineering and test capabili-
ties to North America.

Geographic Expansion
Geographic Expansion

In addition to launching new prod-
ucts, in 2010 we positioned ourselves 
for growth through geographic 
expansion in the Middle East. 
Also, in Tunisia, we moved low-cost 
electronic assembly operations into a 
new plant built to accommodate our 
growing business volume and to effec-
tively implement Lean Manufacturing 
methods.

Strategic Acquisitions
Strategic Acquisitions

Pursuing Leverage Points
Pursuing Leverage Points

In 2010, two strategic acquisitions strengthened 
our position as an important supplier to the “clean 
tech” market, particularly related to water conserva-
tion and energy efficiency. 
In April, we announced that we completed the 
acquisition of Blue Ridge Atlantic Enterprises 
(BRAE). BRAE is a leading provider of engi-
neered rainwater harvesting solutions and ad-
dresses the commercial, institutional and resi-
dential markets. BRAE’s rainwater harvesting 
systems are an integral part of the green building 
movement to conserve water and can contribute 
up to 30% of LEED points available for green 
buildings. 
In June, we announced that we completed the 
acquisition of Austroflex Rohr-Isoliersysteme 
GmbH. Austroflex is an Austrian-based manufac-
turer of pre-insulated flexible pipe for district heat-
ing and solar applications and under-floor radiant 
heating systems. 
The acquisition of Austroflex, in conjunction 
with our existing line of pre-insulated piping 
products, provides us with a full range of pre-in-
sulated PEX tubing, pre-insulated solar tubes and 
under floor heating insulation—strengthening 
our offering in both traditional and alternative 
energy heating markets. Austroflex also expanded 
our distribution capability and positions us as a 
major supplier of pre-insulated pipe systems in 
Europe.

Under an initiative called “One Watts Water”, we 
are pursuing a number of leverage points across our 
company.
In mid 2010, we began the rollout of a new sales 
channel organization for North America. We 
took the separate sales resources from a number 
of our businesses and merged them into one 
unified sales organization focused on five key 
channels: Wholesale, Retail, OEM, Industrial 
and Canada. 
This allows us to create “One Watts Water” teams 
focused on bringing our full offer-
ing of products and brands to each 
of these key channels. Within our 
Wholesale channel, it also has al-
lowed us to create dedicated teams 
focused on distributors, commercial 
construction and residential construc-
tion—enabling us to more effectively 
partner with distributor customers, as 
well as architects, engineers, contrac-
tors and builders going forward.
In addition, to further support our 
global manufacturing and supply 
chain, we initiated a multi-year pro-
gram to fully deploy a single global 
Enterprise Resource Planning (ERP) 
system. This new ERP system will allow us to  
continue to consolidate administrative support  
into shared service centers.

Looking Ahead
Looking Ahead

Although the global economy remains difficult, we 
see opportunities ahead through continued innova-
tion. As our markets change, we are ready to provide 
solutions to our customers’ water-related needs.
As mentioned earlier, in January 2011, President 
Obama signed into law the Reduction of Lead in 
Drinking Water Act, which by January 2014 man-
dates the reduction of lead content nationally in 
plumbing fixtures, fittings and valves to the levels 
now required in California and Vermont. We plan 
to lead the way with one of the largest certified lead 
free product lines in the industry.
Also, recent plumbing code changes are leading 
many states and municipalities to require that all 
new homes be equipped with residential fire sprin-
kler systems. In 2011, we will be releasing a new 
line of residential fire products to serve the growing 
residential fire protection market. 
In addition, in February 2011, we announced our 
intent to acquire Danfoss Socla and the related 
water controls business of Danfoss A/S. Danfoss 
Socla, based in France, is a manufacturer of a wide 
range of water protection valves and flow control 
solutions for the water market and the heating, 
ventilation and air conditioning market. Its prod-
ucts are distributed worldwide for municipal, in-

dustrial, commercial and residential use. We expect 
to close on this acquisition in the second quarter.
This year we will also work to expand our busi-
ness in the Middle East, as well as maintain a focus 
on Asia, where we expect that the expansion of 
plumbing and building codes will provide long-
term opportunities. We also see growing interest in 
Asia in energy and water conservation.
As an important final note, we are moving into 
2011 with new leadership, but with an unwavering 
focus. On January 26, 2011, due to health reasons, 
Patrick O’Keefe resigned as our Chief Executive 
Officer and President. We thank Pat for his leader-
ship and vision, which played an important part in 
our growth and success over the past several years. 
Our Board of Directors subsequently appointed 
David Coghlan, previously our Chief Operating 
Officer, to the position of Chief Executive Officer 
and President, and elected him as a member of our 
Board of Directors.
All associates at Watts Water Technologies will 
continue to work together in 2011 to create share-
holder value through continuous improvement 
and operational excellence; growing our business 
through innovation, key acquisitions, and better 
meeting customer needs; and by pursuing leverage 
points throughout our business.

This  Annual Report on Form 10-K contains statements that are  not historical facts and  are considered
forward-looking within the meaning of  the Private  Securities  Litigation Reform  Act  of 1995. These forward-
looking statements contain projections  of our future  results  of  operations  or our  financial position  or state
other forward-looking information. In some cases you can  identify these forward-looking statements by
words such as ‘‘anticipate,’’ ‘‘believe,’’ ‘‘could,’’ ‘‘estimate,’’ ‘‘expect,’’ ‘‘intend,’’ ‘‘may,’’  ‘‘should,’’  and
‘‘would’’ or similar words. You should not rely  on forward-looking statements because they involve known
and unknown risks, uncertainties and  other factors, some  of  which  are beyond  our control.  These risks,
uncertainties and other factors may cause our  actual  results,  performance or achievements to differ
materially from the anticipated future results, performance or achievements expressed or  implied by the
forward-looking statements. Some of the factors that might cause  these  differences are described under
Item 1A—‘‘Risk Factors.’’ You should  carefully review all of  these factors,  and you  should  be aware that
there may be other factors that could cause these  differences. These  forward-looking statements  were based
on information, plans and estimates at the date of  this report, and, except  as required  by law,  we  undertake
no obligation to update any forward-looking statements to reflect changes in  underlying  assumptions or
factors, new information, future events or  other changes.

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.

Overview

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 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 34  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 Asia. We have a number of manufacturing facilities in lower-cost regions  such as  China, Bulgaria
and Tunisia. In recent years, we have  announced several global restructuring plans to reduce  our
manufacturing footprint in order to reduce  our  costs and to realize additional operating  efficiencies.
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.

Products

We  have a broad range of products in terms  of design distinction,  size and configuration. Our only

product  line that is greater than 10% of our  total revenue  is our water quality product line.  In  2010,
2009 and 2008, water quality products accounted for approximately 15%, 14%  and 17%, respectively,  of
our  total sales. Our principal product lines  include:

• water quality products, including backflow preventers and check valves  for  preventing reverse
flow within water lines and fire protection systems and point-of-use and  point-of-entry  water
filtration and reverse osmosis systems for  both commercial and  residential  applications;

• a wide range of water pressure regulators for  both  commercial and residential  applications;

• drainage products for commercial,  industrial,  marine  and residential applications;

• water supply products for commercial and residential applications;

• temperature and pressure relief valves for water  heaters, boilers  and associated systems;

• thermostatic mixing valves for tempering  water in  commercial and residential applications;

• systems for under-floor radiant applications and hydraulic pump groups for  gas boiler

manufacturers and renewable energy applications, including thermal control and solar and heat
pump control packages; and

• flexible stainless steel connectors for  natural  and liquid  propane gas  in commercial food service

and residential applications.

Customers and Markets

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

chains and OEMs.

3

Wholesalers. Approximately 64% and 65% of our  sales  in 2010 and 2009, respectively,  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% of our sales in both  2010 and  2009 were to DIY  customers. Our DIY

customers demand less technical products, but are highly receptive to innovative designs and  new
product  ideas.

OEMs. Approximately 20% and 19% of our  sales  in 2010 and 2009, 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 2010 and 2009, no customer accounted for more  than 10% of our total net  sales. Our top

ten customers accounted for approximately  $273.6 million, or 22%,  of our  total net sales in 2010  and
$306.4 million, or 25%, of our total net  sales  in 2009. Thousands of other customers constituted the
remaining 78% of our net sales in 2010  and 75% of our  net sales in  2009.

Marketing and Sales

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.

Manufacturing

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 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.

Raw Materials

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  and 2010.  Bronze and  brass are
copper-based alloys. The spot price of copper  increased  approximately  33.2% from December 31, 2009
to December 31, 2010. The fact that we  significantly  source internationally means that several months
of raw materials and work in process  are  moving  through our business at any point in time. We are  not
able to predict whether commodity costs,  including  copper, will  significantly increase or decrease in the
future. If commodity costs continue to 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  margins could be affected.

With limited exceptions, we have multiple suppliers for our  commodities or  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
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 the  commodities and other raw materials used in  our  business  are
such that multiple sources are generally available in the market.

Code Compliance

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.

New Product Development and Engineering

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 $18.6  million, $17.8 million  and
$17.5 million for the years ended December 31, 2010, 2009 and 2008,  respectively.

Effective January 1, 2010, California  and Vermont required 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. On  January 4, 2011, the  federal  government enacted a similar law
that will take effect nationwide in January 2014. We have invested considerable resources over  the past
several years to develop lead-free versions  of  our plumbing  products to comply  with the new laws in
California and Vermont, and we introduced  our  lead-free product  offerings in California  and Vermont
in the fourth quarter of 2009.

Complying with these new requirements  on a  nationwide  basis will pose  a significant  challenge for

us. The transition to comply with the  expected requirements may  cause  our material costs to increase
as suppliers of alternative lead-free metals are currently limited.  We may not succeed in  passing
through these cost increases to our customers.  We may also experience technical  challenges in our
manufacturing process in converting  our present manufacturing operations to 100% lead-free products.
In addition, we could have difficulty  providing sufficient quantities of  our  lead-free  compliant  products
to meet nationwide demand and we could be left with potentially obsolete traditional leaded  product
inventories if customers convert to lead-free offerings faster than anticipated.

Competition

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 quality, brand preference, delivery
times, engineering specifications, plumbing code requirements, price,  technological  expertise 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

Backlog was approximately $84.2 million at February 18, 2011  and was  approximately  $86.6 million

at February 12, 2010. 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 2011.

Employees

As of December 31, 2010, we employed approximately  5,400 people worldwide.  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.

Product Liability, Environmental and Other Litigation Matters

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.

Contingencies

Foreign Corrupt Practices Act Investigation

In 2009, we conducted an investigation into payments  made by  employees of Watts Valve

Changsha Co., Ltd. (CWV), at that time an indirect wholly-owned subsidiary of the  Company in China,
to individuals associated with state-owned agencies that may violate the  United States Foreign Corrupt
Practices Act (FCPA). We voluntarily disclosed this matter to the  Securities  and Exchange  Commission
(SEC) and the Department of Justice  (DOJ).  We have engaged in  negotiations  with the staff of the
SEC and DOJ to resolve potential violations  of  the FCPA relating  to  these payments. Those
negotiations reached a stage at which we were able to estimate  a  probable pre-tax charge in connection
with these matters of approximately $5.3 million, which amount includes estimated disgorgement of
profits and interest. This has been reflected in our results for the year ended December 31,  2010. We
have recorded this charge, net of tax, in  discontinued operations as  these potential violations pertained
to CWV, which had been classified as  discontinued  operations in 2009. We sold CWV in January 2010.
There is  currently no definitive agreement  with the  SEC staff or DOJ for the resolution of this matter,
including with respect to any disgorgement of profits,  fines, penalties or interest  payment, and any
agreement will be subject to the approval by the Commissioners of the SEC  and senior DOJ personnel.
Therefore, there can be no assurance that our negotiations with the SEC  staff and DOJ will result  in a
definitive agreement, and the amount of  the loss upon final disposition of these matters may exceed
our  current estimate.

9

Environmental Remediation

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 that 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 that 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.

Asbestos Litigation

We  are defending approximately 101 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 Litigation

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.

Item 1A. RISK FACTORS.

Current  economic cycles, particularly those  involving 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 recent  economic downturn
may also affect the financial stability of our customers, which could  affect their ability to pay amounts
owed to their 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 adversely impacted 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.

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 price of  copper
increased by 35.6% from January 1, 2010 to February 9,  2011. 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

11

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.

Government regulations could limit or delay  our ability to market or sell our products.

In January 2011, the President of the United  States signed the  Reduction of Lead in Drinking Water

Act, which will reduce the permissable weighted average lead content in faucets, fittings  and valves
intended for use in potable water applications  from 8% to  0.25%  nationwide beginning in January
2014. The new law is consistent with current legislation in  California  and  Vermont that went into effect
in January 2010. We introduced lead-free products for sale  in California and Vermont  and offer a large
selection of lead-free compliant valves  and fittings. Complying with  these  new requirements  on a
nationwide basis will pose a significant challenge for us. The transition to comply with the  expected
requirements may cause our material costs to increase as  suppliers of alternative lead-free metals  are
currently limited. We may not succeed  in passing through these cost increases to our customers.  We
may also experience technical challenges in our manufacturing process in converting our present
manufacturing operations to 100% lead-free products.  In addition, we could have difficulty providing
sufficient quantities of our lead-free  compliant  products to meet  nationwide demand  and we could be
left with potentially obsolete traditional leaded product  inventories if  customers  convert  to  lead-free
offerings faster than anticipated. These requirements could have a material  effect on our financial
condition and results of operation.

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 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. For  example, in February 2011,
we announced our intention to purchase Danfoss Socla (Socla) and certain related business assets.
Socla is a manufacturer of a wide range of water  protection valves and flow control solutions for  the
water market and the heating, ventilation and air conditioning market. The company is based in  France
and its products are distributed worldwide  for municipal, industrial, commercial and  residential use. If
we consummate this acquisition, we expect to spend significant  time and effort in  integrating  the Socla
business and in identifying, completing  and integrating other future 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:

• inadequate internal controls over financial  reporting and  our ability to bring such  controls into
compliance with the requirements of Section 404  of the Sarbanes-Oxley Act  of  2002 in a  timely
manner;

• adverse short-term effects on our reported operating results;

• diversion of management’s attention;

• investigations of, or challenges to, acquisitions by competition  authorities;

• loss of key personnel at acquired companies;  and

12

• unanticipated management or operational problems or  legal liabilities.

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.  If 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. Like other manufacturers and distributors of products designed to control and
regulate fluids and gases, we 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:

• Unexpected geo-political events in foreign countries  in which  we operate could adversely  affect

manufacturing and our ability to fulfill customer  orders.  Currently,  there  is political and
economic unrest in Tunisia where we operate a  low-cost manufacturing facility. Although  our
manufacturing operation has not been materially  affected to  date, we  can give no assurance that
future operations will not be adversely  affected by unforeseen political  events in that country;

13

• trade protection measures and import or  export licensing  requirements, which could increase our

costs of doing business internationally;

• potentially negative consequences from changes in tax laws, which  could  have an adverse impact

on our profits;

• difficulty in staffing and managing widespread operations, which  could  reduce our productivity;

• costs of compliance with differing labor regulations,  especially in  connection with  restructuring

our  overseas operations;

• laws of some foreign countries, which may not protect our  intellectual property rights to the

same extent as the laws of the United States;  and

• unexpected changes in regulatory requirements, which  may be costly and require  time to

implement.

• Foreign exchange rate fluctuations could also  materially affect our reported results.  A portion  of
our  sales and certain portions of our costs, assets and  liabilities  are  denominated  in currencies
other than U.S. dollars and the percentage  of  our revenues denominated in a particular  currency
may not match the percentage of our  expenses denominated  in that currency. Approximately
44.1% of our sales during the year ended  December 31,  2010 were from sales outside of the
U.S. compared to 45.1% for the year ended  December 31, 2009. We cannot predict whether
such currencies as  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 reported results.

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

We  have implemented a number of restructuring plans, the most recent being the  announced
shutdown of two manufacturing facilities in North Carolina. 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.

Future operating results could be negatively  affected by the  resolution of  various uncertain tax  positions  and
by  potential changes to tax incentives

In the ordinary course of our business, there are many transactions  and calculations where the
ultimate tax determination is uncertain.  Significant judgment is required in  determining our worldwide
provision  for income taxes. We periodically assess our exposures related to  our worldwide  provision for
income taxes and believe that we have appropriately  accrued taxes  for contingencies. Any reduction of
these contingent liabilities or additional assessment would  increase or decrease income, respectively,  in
the period such determination was made. Our  income tax filings  are  regularly under audit by tax
authorities and the final determination  of  tax  audits could be materially different  than that which  is
reflected in historical income tax provisions  and  accruals.  As issues arise  during  tax audits we adjust
our  tax accrual accordingly. Additionally, we benefit  from certain tax incentives offered  by  various
jurisdictions. If we are unable to meet  the requirements of such  incentives, our inability to use these
benefits could have a material negative  effect on future  earnings.

14

We are currently a decentralized company,  which presents certain risks.

We  are currently a decentralized company,  which sometimes places significant control and

decision-making powers in the hands  of local management.  This presents various  risks  such as the  risk
of being slower to identify or react to  problems  affecting a key business. Additionally, implementing a
company-wide initiative, such as adopting an  integrated information system, are often more  challenging
and costly to implement.

The requirements to evaluate goodwill and  indefinite-lived intangible 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, 2010, our balance sheet  included goodwill and indefinite-lived intangible assets
of $428.0 million and $46.6 million, respectively.  In  lieu of amortization,  we are  required to perform an
annual impairment review of both goodwill and indefinite-lived intangible assets.  In  performing our
annual reviews in 2010 and 2009, we recognized a  non-cash pre-tax charge of  approximately
$1.4 million and $3.3 million, respectively,  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 to date,  there
can be no assurances that future goodwill impairment  will not  occur. We  perform our annual test  for
indications of goodwill and indefinite-lived 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 2010, our top ten customers accounted  for approximately 22% of our  total net sales with  no one

customer accounting for more than 10%  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, 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.
There can be no assurance that if a large acquisition  is identified that we would have  access to
sufficient capital to complete such acquisition. 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.

15

We are negotiating with the SEC and DOJ with respect to  potential  violations  of the Foreign  Corrupt Practices
Act, and the results of this negotiation  could have a  material adverse effect on  our  business prospects,
operations, financial condition and cash  flow.

As previously disclosed, we conducted an investigation  into  payments made by employees  of  a
former subsidiary of the Company in China to individuals  associated with state-owned agencies  that
may violate the FCPA. We voluntarily  disclosed this  matter to the SEC and  DOJ.  We have engaged in
negotiations with the staff of the SEC  and DOJ to resolve potential  violations of the FCPA relating to
these payments. 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 DOJ and the SEC to review and monitor current and future  business practices with the  goal
of assuring future FCPA compliance,  which could cause us to incur significant costs. 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,  2011, Timothy  P.  Horne
beneficially owned approximately 19.0% 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 99.3% of our  outstanding shares  of  Class  B Common
Stock, which represents approximately  69.4% 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, 2011, there were outstanding 30,102,677 shares of our Class A  Common Stock

and 6,953,680 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.

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 8, 2011, 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 2010  were  $16.4 million, which consisted of
$13.3 million and $3.1 million for Class  A shares and Class B shares, respectively. Aggregate common
stock dividend payments in 2009 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 18, 2011 was 170.

The number of record holders of our  Class B  Common Stock as  of  February 18, 2011  was  6.

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, 2010.

(1) On November 9, 2007, we announced  that our Board of Directors had  authorized  a  stock  repurchase
program. Under the program,  we  may  repurchase  up to an  aggregate  of  3.0 million  shares of  our
Class  A Common  Stock in  open market  purchases or  in privately negotiated  transactions. On
October  28, 2008,  we announced that  we  had  suspended  our stock  repurchase  program.  As  of
December  31, 2008, we had repurchased 2.45 million  shares of  stock  for  a  total  cost  of  $68.1  million.
We did not repurchase any  shares of  stock  in  2010  or in 2009.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS  OF  FINANCIAL CONDITION AND

RESULTS OF OPERATIONS.

Overview

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
136 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:

• water quality products, including backflow preventers and check valves  for  preventing reverse
flow within water lines and fire protection  systems and point-of-use and  point-of-entry  water
filtration and reverse osmosis systems for both commercial and  residential  applications;

• a wide range of water pressure regulators for both commercial and residential  applications;

• drainage products for commercial,  industrial, marine and residential applications;

• water supply products for commercial and residential applications;

• temperature and pressure relief valves for water  heaters, boilers  and associated systems;

• thermostatic mixing valves for tempering  water  in commercial and residential applications;

• systems for under-floor radiant applications and hydraulic pump groups for  gas boiler

manufacturers and renewable energy applications,  including thermal control and solar and heat
pump control packages; and

• flexible stainless steel connectors for natural and  liquid propane gas  in commercial food service

and  residential applications.

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).

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, safe use of water,  increased  demand for
clean water, continued enforcement of plumbing  and building codes and a healthy economic
environment. We have completed 34 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 commercial, industrial and  residential 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.

23

Despite a struggling commercial marketplace, low residential  activity and  some foreign exchange

headwinds, we were able to grow sales organically by 4% and grow  income from  continuing  operations
by 54%. We define organic sales growth  as the increase  or decrease in sales  for the  current period
compared to the prior period, excluding the impact of the change  in foreign currency exchange, and
excluding sales in the: (1) current period from business and  product line acquisitions that are  included
in our actual results of operations for  less than  twelve  months, and (2) prior period from business and
product  line divestitures that are included in our actual results of  operations for the twelve-month
period prior to the divestiture. We saw growth in the  repair and remodeling markets throughout  the
year, we  continued our restructuring programs to right size our manufacturing footprint  and we
sustained our continuous improvement  initiatives to gain productivity in  our operations.

There were two major trends which affected our results during  2010. Stronger first half sales  were

partially offset by declines in the second half in the  DIY market in North America  and OEM market  in
Europe. We believe first half sales were enhanced by the anticipated expiration  of  the home  buying
credit in the U.S., some minor inventory restocking within  the wholesale and retail channels,
incremental lead-free compliant product sales in  California and Vermont, which  started in earnest in
the fourth quarter of 2009, and stronger  OEM and drain sales  in Europe that resulted  from heavier
destocking by these customers in the fourth quarter of 2009. Sales grew organically by 7% as  compared
to the same period in 2009 in each of  the first two quarters of 2010,  whereas we experienced  a 5%
organic sales increase in the third quarter and a 1% decline  in the fourth quarter.

The second major trend we experienced in 2010 was increasing commodity  costs, especially  with

copper-based materials. The spot price  of copper increased by 33.2% from December 31,  2009 to
December 31, 2010. Through productivity gains  and  some selective pricing, we were  able to offset much
of the commodity cost increase. As the year progressed, however, our gross  margins were negatively
affected, especially in certain European  markets. We  have announced plans to increase  our pricing in
2011 to customers in most of our key markets in  reaction to the increased commodity costs, and, a
number of our competitors have also  announced similar  price  increases. We are not able to determine
whether our 2011 pricing initiatives will  be successful  in the marketplace.

We  continually review our business and implement restructuring  plans as  needed. We have recently

announced plans in the U.S. and Europe which  will  shut down and consolidate certain of our
operations. We expect that these announced programs will be completed by  the end of 2011.  Please  see
Note 4 of the Notes to Consolidated Financial Statements for  a more detailed explanation  of our
restructuring activities.

In March 2010, in connection with our manufacturing footprint consolidation, we closed the
operations of Tianjin Watts Valve Company Ltd. (TWVC) and  relocated its manufacturing to other
facilities. On April 12, 2010, we signed a  definitive equity transfer agreement with a  third  party to sell
our  equity ownership and remaining assets of TWVC. The sale is  now  expected  to  be  finalized in the
first quarter of 2011, subject to receiving all applicable  government  approvals. We expect to receive  net
proceeds of approximately $5.9 million  from the sale, of which  we  have already received approximately
$4.3 million in deposits. Also, at the  time of closing, we anticipate recognizing a  gain of approximately
$11.0 million, or $0.29 per share, relating to a favorable tax adjustment and  a favorable cumulative
translation adjustment.

In 2009, our Board of Directors approved the sale of our Watts Valve (Changsha) Co., Ltd.

(CWV) subsidiary. We also liquidated  our  TEAM Precision  Pipework, Ltd.  (TEAM)  subsidiary  through
an administration process under United  Kingdom  law,  as more fully described  in Note  3 of Notes to
Consolidated Financial Statements. We  classified CWV’s and TEAM’s results of operations and  any
related losses as discontinued operations for all periods presented in this report.

24

Acquisitions

During  2010, we made two acquisitions with  an estimated aggregate  purchase price of

$36.1 million, including the estimated fair value of  contingent consideration. We also made  a payment
of approximately $0.5 million on an earn-out of a previously acquired company.

On April 13, 2010, we acquired 100% of the  outstanding stock of  Blue Ridge Atlantic

Enterprises, Inc. (BRAE) located in Oakboro, North Carolina. BRAE  is a provider of engineered rain
water harvesting solutions and addresses  the commercial, industrial and residential markets. BRAE had
annual sales prior to the acquisition of approximately $2.0 million.

On June 28, 2010, we acquired all of the  outstanding stock of Austroflex

Rohr-Isoliersysteme GmbH (Austroflex).  Austroflex  is an Austrian-based  manufacturer of pre-insulated
flexible pipe systems for district heating,  solar  applications and under-floor  radiant heating systems. The
acquisition of Austroflex provides us  with a full  range of pre-insulated PEX tubing, pre-insulated solar
tubes, under-floor heating insulation, and distribution capability and positions us as  a major supplier of
pre-insulated pipe systems in Europe.  Austroflex had  annual sales prior to the acquisition of
approximately $23.0 million.

The results of operations for BRAE  are included  in our North America segment  and the  results of

operations of Austroflex are included  in our Europe segment  since their  respective acquisition dates
and were not material to our consolidated financial  statements.

Recent  Developments

On February 9, 2011, we announced  our intention to acquire  Danfoss Socla and the related water
control business of Danfoss A/S. This announcement  was  made in response to the public disclosure  of
related regulatory filings made with German merger control authorities. The proposed  acquisition  is
subject to the signing of a definitive  purchase agreement and is conditioned  on the receipt  of customary
regulatory approvals. The proposed purchase  price is expected to be in the  range of A115  million to
A120 million.

On February 8, 2011, 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 7, 2011, our Board of Directors elected Merilee Raines to serve  as a member of our
Board of Directors. Ms. Raines was also  appointed by the Board to serve  as a member of  each  of the
Audit Committee and the Nominating  and Corporate Governance  Committee of  the Board of
Directors.

On February 7, 2011, Kenneth J. McAvoy, one of our directors, informed the  Board of his  decision

not to stand for re-election at our 2011  annual meeting of stockholders, which will  be  held on  May 11,
2011. Mr. McAvoy 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. McAvoy currently serves  as a  member  of each of  the  Audit 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.  Gordon  W.  Moran, a member of our
Board, has passed his 72nd birthday,  and therefore  Mr. Moran will  also  not stand  for re-election  at our
2011 annual meeting of stockholders.

On January 26, 2011, Patrick S. O’Keefe resigned from his positions of Chief  Executive Officer,
President and Director. In connection with Mr. O’Keefe’s resignation, we entered into a separation
agreement with Mr. O’Keefe. Pursuant  to  the separation  agreement, Mr. O’Keefe  will continue
employment with us from January 26, 2011  through August 3, 2011 and during this period he will
receive the greater of either aggregate compensation of  $100,000  or short-term disability  benefits if his

25

claim under our short-term disability plan is approved. Following the termination of Mr. O’Keefe’s
employment with us on August 3, 2011, Mr. O’Keefe will be entitled to receive the following payments
and benefits: (i) a cash severance payment of approximately $2.9  million, equal  to  two years of
Mr. O’Keefe’s 2010 annual salary plus  two years of bonus at Mr. O’Keefe’s target bonus  amount  for
2010, payable 50% in an initial lump  sum  payment within  ten days after August 3, 2011 and the
balance in monthly installments over  the  following  24 months; (ii)  accelerated  vesting of  all  unvested
stock options and restricted stock awards (effective February 3, 2011),  and  an extension in the  time of
exercise for the shorter of three years following  Mr. O’Keefe’s  termination  date or the  original  term of
the option, such modification of his options and restricted stock awards  will result in a non-cash charge
of approximately $3.0 million; (iii) other  ancillary  costs for vacation, auto  and professional fees which
total approximately $0.1 million. Total pre-tax  costs under  the separation  agreement are approximately
$6.1 million and will be recorded in our  consolidated statement of operations in the  first  quarter  of
2011. In addition, in accordance with  the provisions of our Management Stock Purchase Plan
Mr. O’Keefe will be paid the unvested  portion, including interest and  accrued dividends, of his
restricted stock units six months after his  termination date.  The  total  amount expected  to  be  paid under
the Management Stock Purchase Plan is  approximately $1.5 million.

On January 26, 2011, our Board of Directors  appointed David  J. Coghlan  to  serve as  Chief

Executive Officer, President and as a  member  of our Board of Directors.

On January 4, 2011, the President of  United States signed  the Reduction  of Lead in Drinking  Water
Act, which will reduce the permissable weighted average lead content in faucets, fittings  and valves used
in potable water applications from 8% to 0.25% nationwide effective in January 2014. The new  law is
consistent with current laws in California  and Vermont that  went into effect  in January 2010.

Organic net sales in 2010 into the North American  wholesale market increased by 6.1% compared

to 2009. This increase was primarily  due  to increased unit sales of our  plumbing and heating and

26

backflow product lines. Organic sales into the North American DIY market in  2010 increased 2.5%
compared to 2009, primarily from increased product sales volume associated with repair and
remodeling activity and new product introductions.

Organic net sales increased in the European  wholesale market by  5.3% compared  to  2009. This

increase was primarily due to a stronger repair and  remodeling market, strong  sales in our  drain
product  line and higher sales into Eastern Europe. Organic  sales  into the  European OEM market  in
2010 were essentially flat with 2009 primarily due  to  increased  sales in hydronic  under-floor manifold
packages offset by heat pump and solar packages whose  lower sales were  driven by renewable energy
subsidies which had expired. Organic  sales  into  the European  DIY market in  2010 increased 6.4%
compared to 2009, primarily from initial new store sales to a  major retail  customer.

The net decrease in sales due to foreign exchange was primarily due to the depreciation of the
euro, partially offset by the appreciation  of the  Canadian dollar against the U.S. dollar. We cannot
predict whether these currencies will  continue  to  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 sales.

Acquired net sales growth in Europe and North America was due to the inclusion of Austroflex

and BRAE, respectively.

Gross Profit. Gross profit and gross profit as a percent of  net sales (gross margin)  for 2010  and

2009 were as follows:

Gross margin increased 1.0 percentage  point in 2010  compared to 2009. North America’s  gross
margin improvement was primarily attributable to increased sales volumes, better absorption at the
factories and productivity gains from  our  Lean  and  Six Sigma cost savings initiatives, partially offset by
increased raw materials costs and inefficiencies due  to  the relocation of manufacturing operations
related to our restructuring program in the U.S.  Europe’s  gross margin  remained  relatively  flat  as
better product mix, with the discontinuance of various low-margin products, increased sales volumes
and better absorption at the factories was offset  by  increased  commodity costs  and inefficiencies from
our  restructuring program in France.

Selling, General and Administrative Expenses. Selling, general and administrative expenses,  or
SG&A expenses, for 2010 increased  $13.2  million, or  4.1%, compared to 2009. The increase in SG&A
expenses was attributable to the following:

The organic increase in SG&A expenses  was primarily due to increased  personnel-related costs,
due diligence and other acquisition costs, IT costs, including  a  new enterprise resource planning system
(ERP system) and related licensing costs,  legal costs  and  increased variable selling expenses due to
higher  sales volumes, partially offset by  reduced product  liability costs. The decrease in SG&A expenses

27

from foreign exchange was primarily  due to the depreciation of the euro against the U.S. dollar. Total
SG&A expenses, as a percentage of sales, remained constant at  26.4% in  each  of 2010 and 2009.

Restructuring and Other Charges.

In 2010, we recorded a charge of $12.6 million primarily for
severance and other costs incurred as  part  of  our  previously announced restructuring programs, as
compared to $16.1 million for 2009. Included in the 2009 restructuring and other charges was a
$1.1 million gain from the 2008 disposition  of  Tianjin  Tanggu Watts Valve Co. Ltd. (TWT).  The gain
was deferred until  all legal and regulatory matters relating to the sale of TWT  were resolved.  For  a
more detailed description of our current  restructuring plans, see Notes  4 and 5 of  Notes to
Consolidated Financial Statements in  this Annual Report on Form  10-K.

Goodwill and Other Indefinite-Lived Intangible Asset Impairment Charges. We recorded $1.4 million

and $3.3 million in 2010 and 2009, respectively, for intangible impairment  charges  related to certain
trademarks and technology. See Note 2 of Notes  to  Consolidated  Financial Statements in this Annual
Report on Form 10-K, for additional information regarding these impairments.

The increase in consolidated organic operating income  was due  primarily to increased  unit volume

sales and stronger  gross margins, partially offset by  increased  SG&A  expenses. The North America
margin increase was primarily due to  increased sales volumes, better  factory absorption levels and the
impact of cost savings initiatives. In 2009, our corporate  segment recorded the  recovery of past legal
expenses, which did not re-occur in 2010.

The net decrease in operating income from  foreign exchange was primarily due to the depreciation

of the euro against the U.S. dollar, partially  offset by the appreciation of 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.

28

Interest Expense.

Interest expense increased $0.8 million, or  3.6%, in 2010  compared to 2009,

primarily due to the issuance of the $75.0 million of senior notes and higher  facility fees on our new
revolving credit agreement partially offset  by  the payment of our $50.0 million of outstanding notes.
See Note 11 of Notes to Consolidated Financial  Statements  in this Annual  Report on  Form 10-K, for
additional information regarding financing  arrangements.

Other, net. Other, net increased $0.9 million, or 75.0%,  in  2010 compared  to  2009, primarily
because foreign currency transactions  resulted in net  gains in 2010, while in 2009  net losses were
recognized.

Income Taxes. Our effective tax rate for continuing operations decreased to 33.2%  in 2010 from

43.3% in 2009. The decrease was primarily  due  to  reversal of  a  valuation allowance  in Europe recorded
during 2010. Also, in 2009 we had a  significant  write-down of assets at one of  our Chinese facilities on
which  we derived no tax benefit. Additionally, we recorded the reversal of previously recognized tax
benefits in China in 2009. These China-related items did not recur in  2010. This  favorable impact was
partially offset by higher European taxes  due to mix of  income by country and recognition  of  tax
expense for the repatriation of earnings  of TWVC in  China  upon  our decision  to  dispose of the entity.

Net Income From Continuing Operations attributable to Watts  Water Technologies,  Inc. Net income

from continuing operations for 2010 was  $63.1 million, or  $1.69  per  common  share, compared  to
$41.0 million, or $1.10 per common share, for 2009. Results for 2010  include an after-tax charge of
$11.2 million, or $0.29 per common share, for restructuring  and other charges  related primarily to
severance and accelerated depreciation compared to an  after-tax restructuring and other charge  of
$18.1 million, or $0.49 per common share, for 2009. The release of the  valuation  allowance on net
operating losses in Europe as noted above  contributed  a tax benefit of $0.08 per common  share to
2010. Results for 2010 and 2009 included a non-cash net after-tax  charge of  $0.9 million, or $0.03 per
share, and $2.6 million, or $0.07 per share, respectively,  to  write off certain intangible assets.  The
depreciation of the euro, partially offset  by the  appreciation  of Canadian dollar against the U.S. dollar,
resulted in a negative impact on our  operations of $0.04  per common share  for 2010 compared to the
comparable period in 2009. 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 loss from discontinued operations in  2010 was

primarily attributable to estimated profits disgorgement  and  legal costs related  to  the FCPA
investigation of our former subsidiary  in China. The loss from  discontinued operations in  2009 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.

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
Bl¨ucher Metal A/S (Bl¨ucher), 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.

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 Bl¨ucher 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 2008 due  to  lower raw  material
costs and cost savings initiatives offset  by  recessionary unit volume sales declines and plant under
absorption.

The organic decrease in SG&A expenses  was  primarily due  to  decreased  variable selling expenses

due to decreased sales, 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 Bl¨ucher. 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  was 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.

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 Bl¨ucher 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.

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% in 2009 from
36.3% in 2008. 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 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 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 2008.

32

Income (Loss) From Discontinued Operations. The income (loss) from discontinued operations was

primarily attributable to the deconsolidation of TEAM, the  loss on the disposal  and loss from
operations of CWV and legal costs related  to  the FCPA investigation offset by the resolution of  the
James Jones Litigation as described in  Note 3  of  Notes to Consolidated Financial Statements.

Liquidity and Capital Resources

2010 Cash Flows

In 2010, we generated $113.4 million of cash from operating activities as compared to

$204.6 million in 2009. We generated approximately $91.0  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), compared  to  free cash flow  of
$181.2 million in 2009. Free cash flow  as a  percentage  of  net income  from continuing operations
attributable to Watts Water Technologies,  Inc. was 144.2%  in 2010 as  compared to 442.0%  in 2009. The
2009 free cash flow results were affected  by the reduction of investment  in accounts receivable  and
inventory driven by the worldwide recession.  This is the third consecutive year that we generated  free
cash flows in excess of net income.

In 2010, we used $57.2 million of net cash from  investing activities primarily for  the purchase of

Austroflex and for capital equipment. We expect to invest approximately $30.0 million in capital
equipment in 2011 as part of our ongoing commitment  to  improve our manufacturing capabilities. We
elected to participate in a settlement offer from UBS, AG (UBS) for all  of our outstanding auction
rate securities (ARS) investments. Under  the terms of  the settlement offer, we  were 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. We  elected to exercise this  right in 2010  and received
$6.5 million from UBS in settlement of all outstanding ARS investments. In  addition,  during  2010, we
invested in nine-month certificates of  deposits  totaling approximately $4.0 million.

In 2010, we generated $6.9 million of net  cash from financing activities primarily from  issuing
$75.0 million, 10-year private placement  notes in June (the Notes), partially offset by the repayment of
$50.0 million in private placement notes  and $16.4 million of dividend  payments.

The Notes were issued pursuant to a Note  Purchase Agreement (the 2010 Note Purchase
Agreement). We will pay interest on the  outstanding  balance  of  the Notes at  the rate  of  5.05% per
annum, payable semi-annually on June 18 and December 18 until  the principal on  the Notes  shall
become  due and payable. We may, at  our  option, upon notice, subject to the  terms of the  2010 Note
Purchase Agreement, prepay at any time all or  part  of  the Notes in an amount not less than $1 million
by paying the principal amount plus a make-whole amount (as defined in the  2010 Note  Purchase
Agreement).

The 2010 Note Purchase Agreement  includes operational  and financial  covenants, with which we
are required to comply, including, among others, maintenance  of certain financial ratios  and restrictions
on additional indebtedness, liens and  dispositions. Events of  defaults under the 2010  Note Purchase
Agreement include failure to comply  with  the financial and operational  covenants, as well  as
bankruptcy and other insolvency events. If an event of default  occurs and is continuing, then a majority
of the note holders have the right to  accelerate  and require  us to repay all the outstanding notes under
the 2010 Note Purchase Agreement.  In  limited  circumstances, such acceleration is  automatic. As of
December 31, 2010 we were in compliance  with all covenants  related  to  the 2010 Note Purchase
Agreement.

On June 18, 2010, we entered into a credit agreement (the Credit Agreement) among the
Company, certain subsidiaries of the Company who  become borrowers  under the Credit Agreement,
Bank of America, N.A., as Administrative Agent,  swing line  lender and  letter of  credit issuer,  and the
other lenders referred to therein. The Credit  Agreement provides for a $300 million, five-year, senior
unsecured revolving credit facility which may be increased by  an additional $150 million under  certain

33

circumstances and subject to the terms  of the Credit Agreement.  The  Credit  Agreement has a  sublimit
of up to $75 million in letters of credit.

Borrowings outstanding under the Credit Agreement bear interest at a fluctuating rate  per  annum

equal to (i) in the case of Eurocurrency  rate loans, the British  Bankers Association  LIBOR rate plus
an applicable percentage, ranging from  1.70% to 2.30%, determined by  reference to our consolidated
leverage  ratio plus, in the case of certain lenders, a  mandatory  cost calculated  in accordance with  the
terms of the Credit Agreement, or (ii)  in the  case of base rate loans and swing  line loans, the highest
of (a)  the federal funds rate plus 0.5%,  (b) the rate of  interest in effect for such day  as announced by
Bank of America, N.A. as its ‘‘prime rate,’’ and (c) the British Bankers Association LIBOR  rate plus
1.0%, plus an applicable percentage,  ranging from 0.70%  to  1.30%, determined by reference to our
consolidated leverage ratio. In addition to paying interest under  the Credit  Agreement, we are also
required to pay certain fees in connection with  the credit  facility, including, but not limited to, a facility
fee and letter of credit fees.

The Credit Agreement matures on June  18, 2015. We may repay  loans  outstanding under the
Credit  Agreement from time to time without  premium or  penalty, other than customary breakage costs,
if any, and subject to the terms of the Credit  Agreement.

Covenant compliance

Under the Credit Agreement, we are required to satisfy and maintain specified financial ratios  and
other financial condition tests. 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 Credit Agreement. Our
Credit  Agreement defines Consolidated  EBITDA to exclude unusual  or  non-recurring  charges  and
gains. We are also required to maintain a consolidated  leverage ratio of consolidated funded debt to
Consolidated EBITDA. Consolidated  funded  debt,  as defined in the Credit 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 and goodwill  impairments.

As of December 31, 2010, our actual financial ratios calculated in accordance with our Credit

Agreement compared to the required  levels under the Credit Agreement  were as  follows:

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, 2010, we were in compliance with all covenants related to the  Credit
Agreement and had $265.3 million of  unused  and  available credit  under the Credit Agreement  and
$34.7 million of stand-by letters of credit outstanding on the  Credit  Agreement. There were no
borrowings under the Credit Agreement  at  December  31, 2010.

We  generated $5.5 million of net cash from operating  activities of discontinued operations in 2010

primarily due to realization of a tax deduction related  to  the James Jones settlement.

We  generated $5.1 million of net cash from investing activities of discontinued operations in  2010

primarily from cash received from the sale of CWV.

Working capital (defined as current assets less current  liabilities) as  December  31, 2010 was
$578.4 million compared to $489.8 million  as of December 31, 2009.  The increase was primarily due to
a cash increase driven by higher operating earnings  and net  cash received through  debt issuance and
retirement. The ratio of current assets to current liabilities was 3.1 to 1  as of December 31,  2010
compared to 2.6 to 1 as of December 31,  2009.

2009 Cash Flows

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,  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 442.0% in 2009  as
compared to 265.3% in 2008 primarily  due to better working capital management,  temporary decreases
in commodity costs, cost 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 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 in ARS with a total par  value of
$6.6 million. These auction rate securities were 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. We exercised our rights  under the settlement in June 2010 as previously  discussed.

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  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.

2008 Cash Flows

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 Bl¨ucher 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.

Non-GAAP Financial Measures

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 5.2%  for 2010 from 9.9% for 2009.  The decrease resulted from
increased cash partially offset by increased  long-term debt.

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. Other companies 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. The cash conversion  rate of free cash flow to net income from
continuing operations is also a measure  of our performance in cash flow generation.

The 2009 free cash flow results were driven by  the worldwide recession,  which caused a  reduction

of investment in accounts receivable and inventory.

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.

(d) includes commodity, capital expenditure commitments and other benefits at  December 31, 2010

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  $34.9 million
as of  December 31, 2010 and $37.0 million  as of December 31, 2009. 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.

Off-Balance Sheet Arrangements

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.

Application of Critical Accounting Policies and Key Estimates

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 2010.

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.

38

Revenue recognition

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.

Allowance for doubtful accounts

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.

Inventory valuation

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.

39

Goodwill and other intangibles

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 2010, we
estimated the fair value of our reporting units using a weighting  of  the income approach  based on  the
present  value of estimated future cash  flows and  the market approach  using  guideline companies  and
selected  transactions. 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 31, 2010  testing date, we  determined we  had
eight reporting units in continuing operations, one which had no goodwill and one which  was acquired
in 2010. Since we acquired BRAE in  April  2010, the estimated fair  value of BRAE is  derived from the
fair value at the date of acquisition as  the acquisition closed just  six months prior to our testing date.

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  2010 and 2009, we recognized  non-cash pre-tax  charges of  approximately  $1.4 million and

$3.3 million, respectively, 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  and  conditioning  reporting 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 31, 2010 testing date, we had  approximately $438.8  million  of goodwill  on our

balance sheet. Our impairment testing  indicated that  the fair values  of the reporting units exceeded the

40

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  31, 2010 impairment test,  we utilized
discount rates ranging from 11.5% to 15.0%  and  long-term terminal growth rates from 3% to 5%
beyond our planning periods.

The Orion reporting unit’s operating results  are being hindered by  the downturn in  the commercial

and institutional end markets in the U.S., where Orion sells  a majority of  its products. Should Orion’s
sales decline because the commercial marketplace deteriorates more than our current  expectations,
then the reporting unit’s goodwill may  be  at risk for impairment in the future. Orion’s goodwill balance
as of  December 31, 2010 was $24.6 million.  As of October  31, 2010, our  last impairment analysis date,
the fair value of the Orion reporting unit exceeded the carrying value by  17%.

Product liability and workers’ compensation costs

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.

41

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.

Legal contingencies

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.

Pension  benefits

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:

• Weighted average discount rate—this rate  is used to estimate the current value of future

benefits. This rate is adjusted based on movement  in long-term interest rates.

• Expected long-term rate of return  on assets—this  rate is used to estimate  future growth  in
investments and investment earnings.  The expected return  is based  upon a  combination  of
historical market performance and anticipated future returns for  a portfolio reflecting the  mix of
equity, debt and other investments indicative  of our plan  assets.

• Rates of increase in compensation  levels—this  rate is used to estimate  projected annual pay
increases, which are used to determine the wage base used to project employees’  pension
benefits at retirement.

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.

Income taxes

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.

New Accounting Standards

In October 2009, the Financial Accounting Standards Board  (FASB)  issued an accounting standard
update to improve disclosures related to fair value measurements. This  update requires new disclosures
when significant transfers in and out  of the  various fair  value levels  occur. This update  requires 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 amends current  disclosure requirements for  postretirement benefit plan assets.
This update is 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.  Adoption of  this
standard did not have a material impact  on  our consolidated  financial statements.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

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 2010, we recorded a $0.5 million gain in other income  associated  with the  change  in the fair  value
of such contracts.

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, 2010.

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 year  ended
December 31, 2009 we recorded a $0.3  million  gain associated with the copper swaps in other expense.

None.

Item 9A. CONTROLS AND PROCEDURES.

As required by Rule 13a-15(b) under the Securities Exchange  Act of 1934, as amended, or
Exchange Act, 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, 2010, 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’s Annual Report on Internal Control  Over  Financial Reporting

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:

(i) pertain to the maintenance of records  that, in reasonable detail, accurately and fairly reflect

the transactions and dispositions of the assets  of  the Company;

(ii) 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

(iii) 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.

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, 2010. 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,  2010.

The audited consolidated financial statements  of  the Company  include the results  of  Austroflex

Rohr-Isoliersysteme GmbH, including  total assets of $41.7 million  and total  revenues of  $10.6 million,
which  the Company acquired on June 28, 2010, but  management’s assessment  does not include  an
assessment of the internal control over  financial reporting of this entity.

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 audit report
on the Company’s internal control over  financial reporting. That  report appears  immediately following
this  report.

Report of Independent Registered Public  Accounting Firm

The Board of Directors and Stockholders
Watts Water Technologies, Inc.:

We  have audited Watts Water Technologies, Inc.’s internal control  over financial  reporting as of
December 31, 2010, 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.

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.

In our opinion, Watts Water Technologies, Inc. maintained, in  all material  respects, effective
internal control over financial reporting as  of December  31, 2010, based  on  criteria established  in
Internal Control—Integrated Framework issued by the  Committee of Sponsoring Organizations of the
Treadway Commission.

Watts Water Technologies, Inc. acquired  Austroflex Rohr-Isoliersysteme GmbH during 2010, and

management excluded from its assessment of the  effectiveness  of Watts  Water  Technologies, Inc.’s
internal control over financial reporting as  of December  31, 2010, Austroflex
Rohr-Isoliersysteme GmbH’s internal control over financial reporting associated with  total assets of
$41.7 million and total revenues of $10.6  million included  in the consolidated financial statements of
Watts Water Technologies, Inc. and subsidiaries  as of and for the year ended December 31,  2010. Our
audit of internal control over financial reporting of Watts  Water Technologies,  Inc. also excluded  an
evaluation of the internal control over financial reporting of Austroflex Rohr-Isoliersysteme GmbH.

46

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, 2010 and 2009,  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, 2010, and our  report  dated March 1, 2011 expressed an
unqualified opinion on those consolidated financial statements.

Report of Independent Registered Public  Accounting Firm

The Board of Directors and Stockholders
Watts Water Technologies, Inc.:

We  have audited the accompanying consolidated balance sheets of Watts Water Technologies, Inc.

and subsidiaries as of December 31, 2010 and 2009, 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, 2010.  In connection with  our audits of the  consolidated
financial statements, we also have audited the financial statement Schedule II—Valuation and
Qualifying Accounts. 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, 2010 and 2009, and the results of their operations  and their  cash flows for each of the
years in the three-year period ended December 31, 2010, 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, present 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, 2010, 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,  2011 expressed an unqualified opinion  on the  effectiveness of
the Company’s internal control over financial reporting.

Notes to Consolidated Financial Statements

(1) Description of Business

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 and  Europe with a presence
in China.

(2) Accounting Policies

Principles of Consolidation

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

Cash equivalents consist of instruments with remaining maturities of three months or less at the

date  of  purchase and consist primarily  of U.S  treasury bills  and  money  market funds, for which  the
carrying  amount is a reasonable estimate  of fair value.

Investment Securities

Investment securities at December 31, 2010  consisted primarily of certificates of deposit  with
original maturities of greater than three  months and at  December  31, 2009 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

Allowance for doubtful accounts includes reserves for bad debts, sales returns and allowances and
cash discounts. 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
and cash discount activities to derive a  reserve for returns and allowances and cash discounts.

Concentration of Credit

The Company sells products to a diversified customer base and, therefore, has no significant

concentrations of credit risk.  In 2010 and 2009, no  customer accounted for 10% or  more of the
Company’s total sales.

Inventories

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 usage  is used as  the
basis for determining the reserve for excess or obsolete  inventories.

Goodwill and Other Intangible Assets

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  31,  2010.

Assets held for sale

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, 2010,  the Company is actively marketing one property and one group of
assets and expects to complete the sale of these assets or group of assets in the next  twelve months. In
2010 and 2009, the Company recorded estimated losses of $1.0 million  and  $7.8 million, respectively,  to
reduce these assets or group of assets down  to  their estimated fair value, less any costs to sell. These
amounts are 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.

Notes to Consolidated Financial Statements  (Continued)

(2) Accounting Policies (Continued)

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), a former 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 weighted average  cost of capital based  on the market and guideline  public
companies for the related businesses 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 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 consisting 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 2010, 2009  and 2008  was

$14.3 million, $13.1 million and $12.2  million, respectively.  Additionally, future amortization expense on
amortizable intangible assets is expected to be $15.4  million  for 2011, $13.5 million for 2012,
$12.4 million for 2013, $12.4 million for  2014,  and $12.1  million  for 2015. 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  9.6 years. Patents, customer relationships,
technology and other amortizable intangibles  have weighted-average  remaining lives of 7.9  years,
7.5 years, 14.5 years and 24.5 years, respectively. Indefinite-lived  intangible assets primarily include
trade names and trademarks.

Adjustments to indefinite-lived intangible assets during the year ended December 31,  2010 relate
primarily to an additional trade name related to the Austroflex Rohr-Isoliersysteme GmbH  acquisition
offset by an impairment of a trade name in our European segment and a  reclassification of $4.4 million
of trade names in our North American  segment to amortizable intangibles.

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 had  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 indefinite-lived intangible assets 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

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, Other than Income Taxes

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

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 2010, the Company reduced its unrecognized tax  benefits by approximately $0.3 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 $0.8 million  worldwide.

As of December 31, 2010, the Company had gross unrecognized  tax benefits  of approximately
$3.8 million approximately $3.5 million of  which, if  recognized, would affect the  effective  tax rate. The
difference between the amount of unrecognized tax  benefits  and the amount that would affect  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:

In February 2011, the Company completed its audit by the Internal  Revenue Service  for the  2007

and  2008 tax years and no material adjustments were made. The Company 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 2004.

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 2007 and later;

in Canada for 2006 and later; and in the  Netherlands for 2006 and later.

Foreign Currency Translation

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.

Stock-Based Compensation

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, 2010, the Company  had three stock-based compensation plans with total

unrecognized compensation costs related to unvested stock-based compensation arrangements of
approximately $11.1 million and a total weighted average remaining term  of 2.5 years. For 2010,  2009
and  2008, the Company recognized compensation costs related to stock-based programs of
approximately $4.7 million, $4.9 million and $5.3  million, respectively, in selling,  general and
administrative expenses. The Company recorded approximately $0.6 million, $0.6 million and
$0.7 million of tax benefits during 2010, 2009 and 2008,  respectively, for the compensation expense
relating to its stock options. For 2010, 2009  and  2008, the  Company recorded approximately
$1.2 million, $1.2 million and $1.1 million, respectively, of tax benefit for  its other stock-based plans.
For 2010, 2009 and 2008, the recognition  of total stock-based compensation expense  impacted  both
basic  and diluted net income per common share by  $0.08, $0.08 and $0.10, respectively.

Net Income Per Common Share

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).

The computation of diluted net income per share for the  years ended December 31,  2010, 2009
and 2008 excludes the effect of the potential exercise  of  options to purchase approximately 0.5 million,
0.9 million and 1.0 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 year ended December 31,  2008,  the Company repurchased approximately 1.6 million

shares of its Class A Common Stock.

Derivative Financial Instruments

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  were 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

Shipping and handling costs included  in selling,  general and  administrative  expense amounted to
$33.5 million, $31.4 million and $39.4  million for the  years ended December 31,  2010, 2009 and 2008,
respectively.

Research and Development

Research and development costs included in selling,  general, and  administrative expense amounted

to $18.6 million, $17.8 million and $17.5 million for the  years ended December 31,  2010, 2009 and
2008, respectively.

Revenue Recognition

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.

Basis of Presentation

Certain amounts in the 2009 consolidated  financial statements  have been reclassified  to  permit
comparison with the 2010 presentation. These  reclassifications had no effect on reported results  of
operations or stockholders’ equity.

Estimates

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.

New Accounting Standards

In October 2009, the Financial Accounting Standards  Board  (FASB)  issued an accounting standard
update to improve disclosures related to fair  value measurements. This  update requires new disclosures
when significant transfers in and out  of the  various  fair value levels  occur. This update  requires a
reconciliation for fair value measurements using significant unobservable inputs (level 3) be prepared

65

Notes to Consolidated Financial Statements  (Continued)

(2) Accounting Policies (Continued)

on a gross basis, separately presenting information  about purchases, sales, issuance and settlements.  In
addition, this update amends current disclosure requirements for  postretirement benefit plan assets.
This update is 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.  Adoption of  this
standard did not have a material impact  on  the Company’s consolidated financial statements.

(3) Discontinued Operations

In September 2009, the Company’s Board of Directors approved the sale of its investment in

CWV. CWV manufactured 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. During 2009, 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  a pre-tax
loss of approximately $8.5 million in 2009, based on the  final agreement with the  buyer. The Company
concluded that the future cash flows  associated  with CWV would be completely eliminated  from the
continuing operations of the Company. As  such,  the Company  classified  CWV’s results 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 had 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 $18.1 million pre-tax non-cash loss.  The Company evaluated the  operations  of  TEAM
and  determined that it would 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 were eliminated from  the
continuing operations of the Company. As  such,  the Company  classified  TEAM’s results of operations
and  the loss from deconsolidation as discontinued operations for all  periods presented.

Discontinued operating losses for 2010  primarily includes an  estimated  reserve in connection with

the Foreign Corrupt Practices Act (FCPA) investigation at CWV  (see  Note 15) and legal  costs
associated with the FCPA investigation.  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  now concluded James Jones
Litigation (see Note 15).

(4) Restructuring and Other (Income) Charges

The Company’s Board of Directors (Board) approves all major  restructuring programs that involve

the discontinuance of significant product lines or the shutdown of facilities  and related capital
expenditures. 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. A
summary of the pre-tax cost by restructuring program is as  follows:

2007 Actions

During  2007, the Company undertook a review  of certain product lines and its overall

manufacturing capacity and initiated a Board approved global restructuring program.  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.

In 2009, the Company reviewed the remaining  activities associated with  the 2007 actions  related to

Europe. Due in large part to this review,  the Company concluded that no further  charges for Europe
would be incurred under this program. In February 2010, the  Board approved  a new  program for
Europe that was launched in 2010, and  included  some of  the components identified  in the 2007  actions.

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 2010  and 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 $1.0 million and $2.3 million,  respectively.  The  remaining excess  was
primarily as a result of higher costs incurred to complete  the consolidation  of  the two  facilities  than
originally anticipated.

2009 Actions

In February 2009, the Board approved a plan to expand the Company’s program  to  consolidate its

manufacturing footprint in North America and China.  The final plan provided  for the  closure of  two
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. Another  facility had originally  been
identified for closure, but its operations  had improved  substantially and therefore was  removed from
the program.

The footprint consolidation pre-tax charge was estimated at approximately $11.7  million,  including

severance charges, relocation costs and  asset write-downs. One-time  tax charges of approximately
$3.9 million were incurred as part of  the  relocations. Approximately 225 positions were eliminated by
this  program. Additionally, the Company spent  approximately $3.3  million in  capital expenditures  to
consolidate operations.

2010 Actions

On February 8, 2010, the Board approved  a restructuring program with respect  to  the Company’s

operating facilities in France. The restructuring program is expected  to  include the consolidation of  five
facilities into two facilities. The consolidation  of the three facilities includes  two manufacturing sites
and one distribution center. The program was  originally 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. The Company revised its forecast to
$15.5 million primarily for additional  severance and legal  costs.  Total net after-tax  charges  for this
restructuring program are expected to be approximately $9.7 million (including $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. The  Company recorded certain severance
costs related to this program in 2009 as the  amounts related to contractual or statutory  obligations.

The additional costs that incurred in  the Company’s Europe  footprint consolidation-restructuring

program primarily came from the unexpected number of employees that elected to make use of the
severance plan, including some higher  paid employees.

On September 13, 2010, the Board approved a restructuring program with  respect to certain of the

Company’s operating facilities in the  United  States.  The  restructuring  program includes  the shutdown
of two manufacturing facilities in North Carolina. Operations at these facilities will be consolidated into
the Company’s manufacturing facilities in New Hampshire,  Missouri and other locations. The program
is expected to include pre-tax charges  totaling  approximately $4.9  million, including costs  for severance,
shutdown costs and equipment write-downs.  Additionally, the Company  is expecting  pre-tax  training
and pre-production set-up costs of approximately $2.0 million.  The  total  net after-tax  charge for this
restructuring program is expected to be approximately $4.1 million (including $0.4 million  in non-cash
charges), with costs being incurred through 2011. The Company  expects to spend approximately
$1.2 million in capital expenditures to  consolidate operations. The  restructuring program is expected to
be completed by the end of the third  quarter of 2011.

(5) Business Acquisitions and Disposition

On June 28, 2010, the Company acquired  100% of the  outstanding  stock  of Austroflex

Rohr-Isoliersysteme GmbH (Austroflex)  for approximately $33.7  million. Austroflex  is an Austrian-
based manufacturer of pre-insulated  flexible pipe systems for district heating,  solar  applications and
under-floor radiant heating systems. The  acquisition  of Austroflex  provides the Company  with a full
range of pre-insulated PEX tubing, pre-insulated  solar tubes, under-floor  heating  insulation, and
distribution capability and positions the Company  as a major  supplier  of pre-insulated pipe systems in
Europe. The Company completed a  purchase  price allocation  that resulted in  the recognition  of
$17.2 million of intangible assets and $12.3 million of goodwill. Intangible assets were  based on fair
value estimates and are comprised primarily of  customer relationships with estimated useful  lives of
8 years and trade names with indefinite lives.  Goodwill is expected to be tax deductible  up to a certain
limit established under Austrian tax rules.  Austroflex had  annual sales prior to the acquisition of
approximately $23.0 million.

On April 13, 2010, the Company acquired 100%  of the outstanding stock of Blue  Ridge Atlantic

Enterprises, Inc. (BRAE) located in Oakboro,  North Carolina for  up to $5.3 million, net of cash
acquired. Of the total purchase price,  $0.5 million was paid at closing and the  remaining $4.8 million is
contingent upon BRAE achieving a certain  performance metric  during the year ending December 31,

(5) Business Acquisitions and Disposition (Continued)

2014, and, to the extent achieved, is expected to be paid in cash  in 2015. The Company recognized  a
liability  of $1.9 million as an estimate of  the acquisition date fair value  of the contingent  consideration,
which is based on the net present value of $3.7 million  which is derived from  the weighted probability
of achievement of the performance metric as of  the date of the acquisition. Failure  to  meet the
performance metric would reduce this liability to $0,  while complete achievement  would increase this
liability  to the full remaining purchase price  of  $4.8 million. Any  change in  the fair value of the
acquisition-related contingent consideration subsequent to the acquisition date is recognized  in earnings
in the  period the estimated fair value  changes.  The  excess fair value of the consideration transferred
over the fair value of the net assets acquired  of $2.7 million was allocated to goodwill and trade name.
None of the goodwill is expected to be tax deductible. BRAE is a provider  of engineered rain water
harvesting solutions and addresses the commercial, industrial and residential markets. BRAE  had
annual sales prior to the acquisition of approximately $2.0 million.

On May 30, 2008, the Company acquired all  of the  outstanding stock of Bl¨ucher Metal A/S
(Bl¨ucher) 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. Bl¨ucher 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. Bl¨ucher 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
Bl¨ucher 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  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.

The results of operations for BRAE  are included  in the Company’s North  America segment and

the results of operations of Austroflex  and Bl¨ucher are included in the Company’s Europe segment
since their respective acquisition dates  and were not material to the Company’s consolidated financial
statements.

Certain acquisition agreements from prior years contain earn-out provisions. In  2010, 2009 and

2008, the Company accrued approximately $0.5 million, $0.5 million and $0.4 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.

At December 31, 2010, the Company has foreign net operating  loss carry forwards of  $31.5 million

for income tax purposes; $1.0 million  of  the losses can be carried forward  indefinitely,  $7.6 million of
the losses expire in 2015, $4.6 million expire in 2016, and $18.3  million expire between 2017-2019. The
net operating losses consist of $1.0 million related to Austrian operations, $22.9 million  to  Netherland
operations, and $7.6 related to Chinese operations.

At December 31, 2010, the Company had a valuation allowance of $9.1 million. In the  U.S.,

$6.9 million relates to capital losses as  management  believes it is not more  likely than not that the
Company would use such losses within the  applicable carryforward period. In China,  a valuation
allowance of $2.2 million relates to the deferred tax assets of TWVC, a Chinese subsidiary, that the
Company believes will not be utilized.  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.

(9) Income Taxes (Continued)

Enacted changes in income tax laws had no  material effect on  the Company in  2010, 2009 or  2008.

Undistributed earnings of the Company’s  foreign subsidiaries amounted  to approximately
$313.0 million at December 31, 2010,  $320.3 million  at December  31, 2009, and $311.7  million at
December 31, 2008. 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, 2010.

(10) Accrued Expenses and Other Liabilities

(11) Financing Arrangements (Continued)

Principal payments during each of the next five years and thereafter  are due as  follows  (in
millions): 2011—$0.7; 2012—$0.7; 2013—$75.7;  2014—$0.7; 2015—$0.8 and thereafter—$300.1.

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
$34.9 million as of December 31, 2010 and $37.0 million as of December 31,  2009. 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 June 18, 2010, the Company entered into a note  purchase  agreement with  certain  institutional

investors (the 2010 Note Purchase Agreement). Pursuant to  the 2010 Note Purchase Agreement,  the
Company issued senior notes of $75.0 million  in principal,  due June  18, 2020. The Company will pay
interest on the outstanding balance of the Notes at the  rate of 5.05%  per  annum, payable
semi-annually on June 18 and December 18 until the principal on  the Notes  shall  become due and
payable. The Company may, at its option, upon notice, and subject to the terms of the 2010  Note
Purchase Agreement, prepay at any time all or  part  of  the Notes in an amount not less than $1 million
by paying the principal amount plus a make-whole amount (as defined in the  2010 Note  Purchase
Agreement).

The 2010 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 defaults under  the 2010 Note
Purchase Agreement include failure  to  comply  with the financial and operational covenants, as well  as
bankruptcy and other insolvency events. If an event of  default  occurs and is continuing, then a majority
of the note holders have the right to accelerate  and require  the Company to repay  all  the outstanding
notes under the 2010 Note Purchase Agreement. In limited circumstances, such  acceleration  is
automatic. As of December 31, 2010, the Company was in compliance  with all covenants  related to the
2010 Note Purchase Agreement.

On June 18, 2010, the Company entered into a credit agreement (the Credit Agreement) among

the Company, certain subsidiaries of the Company who become  borrowers under the  Credit
Agreement, Bank of America, N.A., as  Administrative  Agent, swing line lender and letter of credit
issuer, and the other lenders referred to therein.  The Credit Agreement  provides for a $300 million,
five-year, senior unsecured revolving credit facility  which may be increased by an additional
$150 million under certain circumstances and subject to the terms  of the Credit Agreement.  The Credit
Agreement has a sublimit of up to $75.0 million  in letters of credit. The Credit Agreement replaced the
2006 unsecured revolving credit facility.

Borrowings outstanding under the Credit Agreement bear interest at a fluctuating rate  per  annum

equal to (i) in the case of Eurocurrency  rate loans, the  British  Bankers Association  LIBOR rate plus
an applicable percentage, ranging from  1.70%  to  2.30%, determined by  reference to the Company’s
consolidated leverage ratio plus, in the  case of certain lenders,  a  mandatory  cost calculated  in
accordance with the terms of the Credit Agreement,  or  (ii) in  the case of base rate loans  and swing  line
loans, the highest of (a) the federal funds rate  plus 0.5%, (b) the  rate of  interest in effect for  such day
as announced by Bank of America, N.A.  as its ‘‘prime rate,’’ and (c) the British Bankers Association
LIBOR rate plus 1.0%, plus an applicable  percentage, ranging from 0.70% to 1.30%, determined  by

Agreement, the Company is also required  to  pay  certain fees in connection with the  credit facility,
including, but not limited to, a facility  fee and letter of credit fees. The  Credit  Agreement expires on
June 18, 2015. The Company may repay loans  outstanding under the Credit Agreement from time to
time without premium or penalty, other than customary breakage  costs,  if any,  and subject  to  the terms
of the Credit Agreement.

Under the Credit Agreement, the Company is required to satisfy  and maintain  specified financial

ratios and other financial condition tests. As of December 31, 2010,  the Company was  in compliance
with all covenants related to the Credit  Agreement and had  $265.3 million of unused and  available
credit under the Credit Agreement and $34.7 million of stand-by letters of credit outstanding on the
Credit Agreement. There were no borrowings under the Credit Agreement at December 31, 2010.

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, 2010, 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 30th and October 30th of each year.

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  May  2013. The payment of interest on  the
senior unsecured notes was due semi-annually on  May 15th  and November 15th  of each year. In  May
2010, the Company repaid $50.0 million in principal of  4.87% senior notes due upon  maturity. As  of
December 31, 2010, the Company was in compliance with all covenants related to the note  purchase
agreement.

(12) Common Stock

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, 2010, the Company has reserved a
total of 3,668,183 of Class A Common  Stock for issuance under its stock-based compensation plans and
6,953,680 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 3.0 million shares of  its Class  A Common Stock. As of December 31, 2010,  the

(13) Stock-Based Compensation

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, 2010, 2,003,598  shares of Class A
Common Stock were authorized for future grants of new equity  awards under the Company’s stock
incentive plans.

The Company 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,
over a one-year period, 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 ratably 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.

2004 Stock Incentive Plan

At December 31, 2010, total unrecognized compensation cost  related to the unvested stock options

was approximately $5.2 million with a  total weighted average  remaining term  of 3.0 years. For 2010,
2009 and 2008, the Company recognized compensation  cost of $1.7  million,  $1.7 million and
$2.3 million, respectively, in selling, general and administrative expenses.

As of December 31, 2010, the aggregate intrinsic values of exercisable  options were approximately

$6.9 million, representing the total pre-tax  intrinsic value,  based on  the Company’s closing Class A
Common Stock price of $36.59 as of December 31, 2010,  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 2010, 2009 and 2008 was  approximately $2.7 million, $0.3 million and $0.8 million,
respectively.

Upon exercise of options, the Company  issues  shares of Class  A  Common  Stock.

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:

41.3% 41.2% 35.6%

1.9% 2.8% 3.5%

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%, 6.75% and 15.0%  for 2010,  2009 and  2008, respectively, 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 $12.36, $9.70 and $10.10 for the  years  ending December  31, 2010,  2009 and  2008,
respectively.

The total fair value of shares vested during 2010,  2009 and 2008 was $1.5  million,  $2.1 million and

$1.4 million, respectively. At December 31, 2010, total unrecognized  compensation cost related to
unvested restricted stock was approximately $4.1 million with a total weighted average remaining term
of 2.1  years. For 2010, 2009 and 2008,  the Company recognized compensation  costs of $1.8 million,
$2.0 million and $1.8 million, respectively,  in selling,  general  and  administrative expenses.  The
Company applied an estimated forfeiture  rate of  9.75%, 5.2% and 10.0% for 2010, 2009 and  2008,
respectively, for restricted stock issued to key employees. The aggregate intrinsic  value of restricted
stock granted and outstanding approximated $5.9 million representing  the total pre-tax intrinsic value
based on the Company’s closing Class  A  Common Stock  price of $36.59 as of December 31, 2010.

Management Stock Purchase Plan

Total unrecognized compensation cost related to unvested RSUs was approximately $1.8  million at
December 31, 2010 with a total weighted average remaining  term of 1.9 years. For 2010, 2009 and 2008
the Company recognized compensation  cost of $1.2 million, $1.2 million and $1.2 million, respectively,

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 RSUs. The expected life (estimated period of time  outstanding) of RSUs
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 6.3% of 5.2% and 10.0%  for 2010, 2009 and 2008, respectively, 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 $12.81, $8.14 and $11.44 during 2010, 2009 and 2008, respectively.

The Company distributed dividends of $0.44  per  share for 2010,  2009 and 2008 on the Company’s

Class A Common Stock and Class B Common Stock.

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: futures  contracts, private
placements, options, limited partnerships, venture-capital investments, 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  50%/50% 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.

(14) Employee Benefit Plans (Continued)

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, 2010  and 2009 were
$0.5 million in each year, respectively, and for the year  ended December  31, 2008 was $0.6 million.
Charges for European pension plans approximated $3.5 million, $2.8 million and $3.3 million for the
years ended December 31, 2010, 2009 and 2008,  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 $0.4  million 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).

James Jones Litigation

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. 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.

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.  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,

(15) Contingencies and Environmental  Remediation (Continued)

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  2009 to reduce previously
recorded estimates of the loss and related  fees  to  the amounts noted above.

Foreign Corrupt Practices Act Investigation

In 2009, the Company conducted an  investigation  into  payments made by employees of CWV, at
that time an indirect wholly-owned subsidiary  of the  Company in China,  to individuals associated  with
state-owned agencies that may violate the  United States Foreign Corrupt Practices Act  (FCPA). The
Company voluntarily disclosed this matter  to  the Securities and Exchange Commission (SEC)  and the
Department of Justice (DOJ). The Company  had engaged in negotiations  with the staff of the  SEC  and
DOJ to resolve potential violations of  the FCPA relating to  these  payments. Those  negotiations  reached
a stage at which the Company was able to estimate  a  probable pre-tax charge in  connection with  these
matters of approximately $5.3 million, which  amount  includes estimated disgorgement of profits and
interest. This has been reflected in its results  for the year ended  December 31,  2010. The Company  had
recorded this charge, net of tax, in discontinued operations as these potential violations  pertained to
CWV, which had been classified as discontinued operations in 2009. The  Company sold CWV  in
January 2010. There is currently no definitive agreement with the SEC staff  or DOJ for  the resolution
of this  matter, including with respect to any disgorgement of profits, fines, penalties or interest
payment, and any agreement will be subject  to  the approval by  the Commissioners of the SEC  and
senior DOJ personnel. Therefore, there  can be no assurance that the  Company’s negotiations with the
SEC staff and DOJ will result in a definitive agreement, and the  amount  of  the loss  upon final
disposition of these matters may exceed the  Company’s  current estimate.

Environmental Remediation

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 that 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 it, the  Company 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 the Company 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.

Asbestos Litigation

The Company is defending approximately 101 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 Litigation

Other lawsuits and proceedings or claims, arising  from  the ordinary course of operations, are also

pending or threatened against the Company. 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.

(16) Financial Instruments

Fair Value

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 5.47% senior notes  due 2013, 5.85% senior notes due 2016 and
5.05% senior notes due 2020 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

The Company elected to participate in a settlement  offer from UBS, AG  (UBS) for all of its

outstanding auction rate securities (ARS) investments. Under the terms  of the settlement offer,  the
Company was issued rights by UBS entitling the Company to require UBS  to  purchase  the underlying
ARS at par value during the period from June 30, 2010,  through July 2, 2012.  The  Company elected to
exercise this right and, on July 1, 2010  received $6.3 million from UBS in settlement of all outstanding
ARS investments. The Company had previously received $0.2 million from  UBS during the  first  quarter
of 2010. The Company recorded income  of approximately $0.1 million and $0.4  million to other
(income) expense in the consolidated  statement of operations for its investment in  ARS  in 2010 and
2009, respectively.

As discussed in Note 5, a contingent liability of  $1.9 million  was  recognized  as an estimate of the
acquisition date fair value of the contingent consideration  in the BRAE acquisition.  This liability was
classified as  Level 3 under the fair value hierarchy as it  was  based on the weighted probability  of
achievement of a future performance metric as of the  date of the acquisition, which was not observable
in the  market.

Short-term investment securities as of  December 31,  2010 consist of certificates of deposit with

remaining maturities of greater than three months at the date of purchase,  for which the carrying
amount is a reasonable estimate of fair  value.

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

The Company uses financial instruments  from time  to  time 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 $9
to $15 million in open contracts at the end of any given quarter.  At  December  31, 2010, the  Company
had  contracts for notional amounts aggregating  approximately $9.0  million. 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,
2010 and 2009, the Company had no outstanding swaps.

(19) Subsequent Events

On February 9, 2011, the Company announced its intention to acquire Danfoss Socla and the
related water control business of Danfoss A/S. This announcement  was  made  in response to the public
disclosure of related regulatory filings made with German merger control authorities. The proposed
acquisition is subject to the signing of a definitive purchase agreement  and  is conditioned on the
receipt of customary regulatory approvals. The proposed  purchase  price is expected to be in  the range
of A115 million to A120 million.

On February 8, 2011, the Company 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 January 26, 2011, Patrick S. O’Keefe resigned  from his positions of Chief  Executive Officer,

President and Director. In connection with Mr.  O’Keefe’s resignation, the Company entered into a
separation agreement with Mr. O’Keefe. Pursuant to the separation agreement,  Mr.  O’Keefe will
continue employment with the Company from January  26, 2011 through August 3, 2011 and  during  this
period  he will receive the greater of either  aggregate compensation of $100,000 or  short-term disability
benefits if his claim under our short-term disability plan is approved. Following the termination of
Mr. O’Keefe’s employment with the Company on August 3, 2011, Mr. O’Keefe will be entitled  to
receive the following payments and benefits: (i)  a cash severance payment  of  approximately
$2.9 million, equal to two years of Mr. O’Keefe’s  2010 annual salary plus two  years  of  bonus at
Mr. O’Keefe’s target bonus amount for  2010, payable  50% in  an initial lump sum payment  within ten
days after August 3, 2011 and the balance in monthly installments over the following 24 months;
(ii) accelerated vesting of all unvested stock options and restricted stock  awards (effective February 3,
2011), and an extension in the time of exercise for the shorter of three years  following  Mr.  O’Keefe’s
termination date or the original term of the option, such modification of his options  and restricted
stock awards will result in a non-cash charge of  approximately $3.0 million; (iii) other ancillary  costs for
vacation, auto and professional fees which total approximately $0.1 million.  Total pre-tax costs under
the separation agreement are approximately $6.1 million and will be recorded in the Company’s
consolidated statement of operations in  the first  quarter of 2011. In addition, in accordance with the
provisions of the Company’s Management Stock Purchase Plan Mr.  O’Keefe will be paid the  unvested
portion, including interest and accrued dividends, of his restricted stock units six months after  his
termination date. The total amount expected to be paid  under the Management  Stock Purchase Plan is
approximately $1.5 million.

On January 26, 2011, the Company’s Board  of  Directors appointed David J.  Coghlan to serve as

Chief Executive Officer, President and as a member  of its  Board of Directors.
