Notes to condensed consolidated financial statements (unaudited)

1. Basis of Presentation and Responsibility for Interim Financial Statements

We prepared the unaudited condensed consolidated financial statements following the requirements of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the United States can be condensed or omitted.

We are responsible for the unaudited financial statements included in this document. The financial statements include all normal recurring adjustments that are considered necessary for the fair presentation of our financial position and operating results. As these are condensed financial statements, one should also read our consolidated financial statements and notes thereto for the year ended December 31, 2010, which are included in our Current Report on Form 8-K dated May 2, 2011.

Revenues, expenses, cash flows, assets and liabilities can and do vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be indicative of those for a full year.

Our fiscal year ends on December 31. We report our interim quarterly periods on a 13-week basis ending on a Saturday.

In connection with preparing the unaudited condensed consolidated financial statements for the six months ended July 2, 2011, we have evaluated subsequent events for potential recognition and disclosure through the date of this filing.

2. New Accounting Standards

In June 2011, the Financial Accounting Standards Board (FASB) amended its guidance on the presentation of comprehensive income in financial statements to improve the comparability, consistency and transparency of financial reporting and to increase the prominence of items that are recorded in other comprehensive income. The new accounting guidance requires entities to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. The provisions of this new guidance are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011.

There were no other new accounting pronouncements issued or effective during the first six months of 2011 that have had or are expected to have a material impact on the Condensed Consolidated Financial Statements.

3. Stock-based Compensation

Total stock-based compensation expense was $4.8 million and $5.6 million for the three months ended July 2, 2011 and July 3, 2010, respectively, and was $10.5 million and $12.4 million for the six months ended July 2, 2011 and July 3, 2010, respectively.

During the first half of 2011, restricted shares and restricted stock units of our common stock were granted under the 2008 Omnibus Stock Incentive Plan to eligible employees with a vesting period of three to four years after issuance. Restricted share awards and restricted stock units are valued at market value on the date of grant and are typically expensed over the vesting period. Total compensation expense for restricted share awards and restricted stock units was $2.5 million and $2.8 million for the three months ended July 2, 2011 and July 3, 2010, respectively, and was $5.8 million and $6.5 million for the six months ended July 2, 2011 and July 3, 2010, respectively.

During the first half of 2011, option awards were granted under the 2008 Omnibus Stock Incentive Plan with an exercise price equal to the market price of our common stock on the date of grant. Option awards are typically expensed over the vesting period. Total compensation expense for stock option awards was $2.3 million and $2.8 million for the three months ended July 2, 2011 and July 3, 2010, respectively, and $4.7 million and $5.9 million for the six months ended July 2, 2011 and July 3, 2010, respectively.

We estimated the fair value of each stock option award on the date of grant using a Black-Scholes option pricing model, modified for dividends and using the following assumptions:

	July 2, 2011			July 3, 2010
Expected stock price volatility		35.5	%		35.0	%
Expected life		5.5 yrs			5.5 yrs
Risk-free interest rate		2.12	%		2.25	%
Dividend yield		2.16	%		2.20	%

The weighted-average fair value of options granted during the second quarter of 2011 and 2010 were $10.89 and $9.80 per share, respectively.

These estimates require us to make assumptions based on historical results, observance of trends in our stock price, changes in option exercise behavior, future expectations and other relevant factors. If other assumptions had been used, stock-based compensation expense, as calculated and recorded under the accounting guidance could have been affected.

7

Pentair, Inc. and Subsidiaries

Notes to condensed consolidated financial statements (unaudited)

We based the expected life assumption on historical experience as well as the terms and vesting periods of the options granted. For purposes of determining expected volatility, we considered a rolling average of historical volatility measured over a period approximately equal to the expected option term. The risk-free rate for periods that coincide with the expected life of the options is based on the U.S. Treasury Department yield curve in effect at the time of grant.

4. Earnings Per Common Share

Basic and diluted earnings per share were calculated using the following:

	Three months ended				Six months ended
In thousands	July 2, 2011		July 3, 2010		July 2, 2011		July 3, 2010
Weighted average common shares outstanding — basic		98,333		98,208		98,190		98,081
Dilutive impact of stock options and restricted stock		1,732		1,430		1,635		1,354
Weighted average common shares outstanding — diluted		100,065		99,638		99,825		99,435
Stock options excluded from the calculation of diluted earnings per share because the exercise price was greater than the average market price of the common shares		—		2,886		—		4,056

5. Restructuring

Restructuring accrual activity recorded on the Condensed Consolidated Balance Sheets is summarized as follows for the six months ended July 2, 2011 and July 3, 2010 and year ended December 31, 2010:

In thousands	July 2, 2011			December 31, 2010			July 3, 2010
Beginning balance	$	3,994		$	14,509		$	14,509
Cash payments and other		(909	)		(10,515	)		(7,524	)
Ending balance	$	3,085		$	3,994		$	6,985

6. Acquisitions

On May 12, 2011, we acquired as part of our Water Group the Clean Process Technologies (“CPT”) division of privately held Norit Holding B.V. for $715.3 million (€502.7 million translated at the May 12, 2011 exchange rate). CPT’s results of operations have been included in our consolidated financial statements since the date of acquisition. CPT is a global leader in membrane solutions and clean process technologies and significantly expands our position in the high growth water and beverage filtration and separation segments. CPT provides sustainable purification systems and solutions for desalination, water reuse, industrial applications and beverage segments that effectively address the increasing challenges of clean water scarcity, rising energy costs and pollution. CPT’s product offerings include innovative ultrafiltration and nanofiltration membrane technologies, aseptic valves, CO₂ recovery and control systems and specialty pumping equipment. Based in the Netherlands, CPT has broad sales diversity with the majority of 2010 revenues generated in European Union countries and Asia-Pacific

The fair value of the business acquired was allocated to the assets acquired and liabilities assumed based on their estimated fair values. The excess of the fair value acquired over the identifiable assets acquired and liabilities assumed is reflected as goodwill. Goodwill recorded as part of the purchase price allocation was $451.8 million, none of which is tax deductible. Identifiable intangible assets

Notes to condensed consolidated financial statements (unaudited)

acquired as part of the acquisition were $197.2 million, including definite-lived intangibles, such as customer relationships, proprietary technology and trade names with a weighted average amortization period of approximately 10 years.

The CPT business records certain long term contracts under the percentage-of-completion method of accounting. Under this method, sales and gross profit are recognized as work is performed based on the relationship between actual costs incurred and total estimated costs at completion.

These pro forma condensed consolidated financial results have been prepared for comparative purposes only and include certain adjustments, such as increased interest expense on acquisition debt. They do not reflect the effect of costs or synergies that would have been expected to result from the integration of the acquisition. The pro forma information does not purport to be indicative of the results of operations that actually would have resulted had the combination occurred at the beginning of each period presented, or of future results of the consolidated entities.

On January 31, 2011 we acquired as part of our Water Group all of the outstanding shares of capital stock of Hidro Filtros do Brasil (“Hidro Filtros”) for cash of $14.9 million and a note payable of $2.1 million. The Hidro Filtros results of operations have been included in our consolidated financial statements since the date of acquisition. Hidro Filtros is a leading manufacturer of water filters and filtering elements for residential and industrial applications operating in Brazil and neighboring countries. Goodwill recorded as part of the purchase price allocation was $10.1 million, none of which is tax deductible. Identified intangible assets acquired as part of the acquisition were $6.3 million including definite-lived intangibles, primarily customer relationships, of $5.5 million with an estimated life of 13 years. The proforma impact of this acquisition was deemed to be not material.

Additionally, during the first six months of 2011, we completed other small acquisitions with purchase prices totaling $4.6 million, consisting of $2.9 million in cash and $1.7 million as a note payable, adding to our Water Group. Total goodwill recorded as part of the purchase price allocation was $4.3 million, none of which is tax deductible. The proforma impact of these acquisitions was deemed to be not material.

Total transaction costs related to acquisition activities for the six months ended July 2, 2011 were $7.8 million, which were expensed as incurred and recorded in Selling, general and administrative in our Condensed Consolidated Statements of Income.

Long-term debt						$	1,384,167		$	702,521		$	734,472

The fair value of total debt excluding the deferred gain on interest rate swaps, was $1,440.1 million, $745.9 million and $772.6 million as of July 2, 2011, December 31, 2010 and July 3, 2010, respectively.

On May 9, 2011, we completed a public offering of $500 million aggregate principal amount of our 5.000% Senior Notes due 2021 (the “Notes”). The Notes are guaranteed by each of our wholly-owned domestic subsidiaries. These wholly-owned domestic subsidiaries may also be a guarantor under our primary bank credit facility. We used the net proceeds from the offering of the Notes to finance in part the CPT acquisition.

On April 28, 2011, we entered into a Fourth Amended and Restated Credit Agreement (the “Credit Facility”). The Credit Facility replaced our previous $800 million revolving credit facility. The Credit Facility creates an unsecured, committed credit facility of up to $700 million, with multi-currency sub facilities to support investments outside the U.S. The Credit Facility expires on April 28, 2016. Borrowings under the Credit Facility currently bear interest at the rate of London Interbank Offered Rate (“LIBOR”) plus 1.75%. Interest rates and fees on the Credit Facility will vary based on our credit ratings. We used borrowings under the Credit Facility to fund a portion of the CPT acquisition and to fund ongoing operations.

We are authorized to sell short-term commercial paper notes to the extent availability exists under the Credit Facility. We use the Credit Facility as back-up liquidity to support 100% of commercial paper outstanding. Our use of commercial paper as a funding vehicle depends upon the relative interest rates for our commercial paper compared to the cost of borrowing under our Credit Facility. As of July 2, 2011, we had no commercial paper outstanding.

Total availability under our existing Credit Facility was $437.9 million as of July 2, 2011, which was not limited by any of the credit agreement’s financial covenants as of that date.

Our debt agreements contain certain financial covenants, the most restrictive of which is a leverage ratio (total consolidated indebtedness, as defined, over consolidated net income before interest, taxes, depreciation, amortization and non-cash compensation expense (“EBITDA”), as defined) that may not exceed 4.0 to 1.0 as of July 2, 2011, 3.75 to 1.0 as of October 1, 2011, and 3.5 to 1.0 as of the last date of each of our fiscal quarters thereafter. We were in compliance with all financial covenants in our debt agreements as of July 2, 2011.

In addition to the Credit Facility, we have $40.0 million and $39.2 million (€27.0 million translated at the July 2, 2011 exchange rate) of other credit facilities, of which $21.8 (€15.0 million translated at the July 2, 2011 exchange rate) is committed until April 2016. Borrowings under these credit facilities bear interest at the rates of Euro Interbank Offered Rate (“Euribor”) plus 1.5% to 1.75%. We had $3.4 million and $18.0 million (€12.4 million translated at the July 2, 2011 exchange rate) of borrowings under these credit facilities as of July 2, 2011. Additionally, as part of the CPT acquisition we assumed certain capital leases with an outstanding balance of $18.3 million at July 2, 2011.

We have $105 million of outstanding private placement debt maturing in May 2012. We classified this debt as long-term as of July 2, 2011 as we have the intent and ability to refinance such obligation on a long-term basis under the Credit Facility.

Debt outstanding at July 2, 2011 matures on a calendar year basis as follows:

10. Derivatives and Financial Instruments

Fair value measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date:

Level 1:	Valuation is based on observable inputs such as quoted market prices (unadjusted) for identical assets or liabilities in active markets.
Level 2:	Valuation is based on inputs such as quoted market prices for similar assets or liabilities in active markets or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
Level 3:	Valuation is based upon other unobservable inputs that are significant to the fair value measurement.

In making fair value measurements, observable market data must be used when available. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement.

Cash-flow Hedges

In September 2005, we entered into a $100 million interest rate swap agreement with several major financial institutions to exchange variable rate interest payment obligations for fixed rate obligations without the exchange of the underlying principal amounts in order to manage interest rate exposures. The effective date of the fixed rate swap was April 25, 2006. The swap agreement has a fixed interest rate of 4.68% and expires in July 2013. The fixed interest rate of 4.68% plus the .60% interest rate spread over LIBOR results in an effective fixed interest rate of 5.28%. The fair value of the swap was a liability of $8.3 million, $9.4 million and $10.2 million at July 2, 2011, December 31, 2010 and July 3, 2010, respectively, and was recorded in Other non-current liabilities on the Condensed Consolidated Balance Sheets.

In August 2007, we entered into a $105 million interest rate swap agreement with a major financial institution to exchange variable rate interest payment obligations for a fixed rate obligation without the exchange of the underlying principal amounts in order to manage interest rate exposures. The effective date of the swap was August 30, 2007. The swap agreement has a fixed interest rate of 4.89% and expires in May 2012. The fixed interest rate of 4.89% plus the .50% interest rate spread over LIBOR results in an effective fixed interest rate of 5.39%. The fair value of the swap was a liability of $4.2 million, $6.4 million and $7.9 million at July 2, 2011, December 31, 2010 and July 3, 2010, respectively, and was recorded in Other non-current liabilities on the Condensed Consolidated Balance Sheets.

The variable to fixed interest rate swaps are designated as cash-flow hedges. The fair value of these swaps are recorded as assets or liabilities on the Condensed Consolidated Balance Sheets. Unrealized income/expense is included in Accumulated other comprehensive income (“OCI”) and realized income/expense and amounts due to/from swap counterparties, are recorded in Net interest expense in our Condensed Consolidated Statements of Income. We realized incremental expense resulting from the swaps of $4.7 million for each of the six months ended July 2, 2011 and July 3, 2010.

The variable to fixed interest rate swaps are designated as and are effective as cash-flow hedges. The fair value of these swaps are recorded as assets or liabilities on the Condensed Consolidated Balance Sheets, with changes in their fair value included in OCI.

12

Pentair, Inc. and Subsidiaries

Notes to condensed consolidated financial statements (unaudited)

Derivative gains and losses included in OCI are reclassified into earnings at the time the related interest expense is recognized or the settlement of the related commitment occurs.

Failure of one or more of our swap counterparties would result in the loss of any benefit to us of the swap agreement. In this case, we would continue to be obligated to pay the variable interest payments per the underlying debt agreements which are at variable interest rates of 3 month LIBOR plus .50% for $105 million of debt and 3 month LIBOR plus .60% for $100 million of debt. Additionally, failure of one or all of our swap counterparties would not eliminate our obligation to continue to make payments under our existing swap agreements if we continue to be in a net pay position.

Our interest rate swaps are carried at fair value measured on a recurring basis. Fair values are determined through the use of models that consider various assumptions, including time value, yield curves, as well as other relevant economic measures, which are inputs that are classified as Level 2 in the valuation hierarchy defined by the accounting guidance.

In April 2011 as part of our planned debt issuance to fund the CPT acquisition, we entered into interest rate swap contracts to hedge movement in interest rates through the expected date of closing for a portion of the expected fixed rate debt offering. The swaps had a notional amount of $400 million with an average interest rate of 3.65%. In May 2011, upon the sale of the Notes, the swaps were terminated at a cost of $11.0 million. Because we used the contracts to hedge future interest payments, this amount is recorded in Prepaid expenses and other current assets within the Condensed Consolidated Balance Sheets and will be amortized as interest exposure over the 10 year life of the Notes.

We manage our economic and transaction exposure to certain market-based risks through the use of foreign currency derivative instruments. Our objective in holding derivatives is to reduce the volatility of net earnings and cash flows associated with changes in foreign currency exchange rates.

Foreign currency contract

In March 2011, we entered into a foreign currency option contract to reduce our exposure to fluctuations in the euro related to the planned CPT acquisition. The contract had a notional amount of €286.0 million, a strike price of 1.4375 and a maturity date of May 13, 2011. The fair value of the contract was an asset of $2.8 million at April 2, 2011 and was recorded in Prepaid expenses and other current assets on the Condensed Consolidated Balance Sheets. In May 2011, we sold the foreign currency option contract for $1.0 million. The net cost of $2.1 million is recorded in Selling, general and administrative on the Condensed Consolidated Statements on Income.

(1) Deferred compensation plan assets include mutual funds and cash equivalents for payment of certain non-qualified benefits for retired, terminated and active employees. The fair value of these assets was based on quoted market prices.

11. Income Taxes

The provision for income taxes consists of provisions for federal, state and foreign income taxes. We operate in an international environment with operations in various locations outside the U.S. Accordingly, the consolidated income tax rate is a composite rate reflecting the earnings in the various locations and the applicable rates.

13

Pentair, Inc. and Subsidiaries

Notes to condensed consolidated financial statements (unaudited)

The effective income tax rate for the six months ended July 2, 2011 was 30.4% compared to 33.6% for the six months ended July 3, 2010. We continue to actively pursue initiatives to reduce our effective tax rate. The tax rate in any quarter can be affected positively or negatively by adjustments that are required to be reported in the specific quarter of resolution.

The total gross liability for uncertain tax positions was $24.8 million, $24.3 million and $27.9 million at July 2, 2011, December 31, 2010 and July 3, 2010, respectively. We record penalties and interest related to unrecognized tax benefits in Provision for income taxes and Net interest expense, respectively, on the Condensed Consolidated Statements of Income, which is consistent with our past practices.

Overview

We are a focused diversified industrial manufacturing company comprised of two operating segments: Water and Technical Products. Our Water Group is a global leader in providing innovative products and systems used worldwide in the movement, storage, treatment and enjoyment of water. Our Technical Products Group is a leader in the global enclosures and thermal management markets, designing and manufacturing standard, modified and custom enclosures that house and protect sensitive electronics and electrical components and protect the people that use them. In 2010, our Water Group and Technical Products Group accounted for approximately 2/3 and 1/3 of total revenues, respectively.

Our Water Group has progressively become a more important part of our business portfolio with sales increasing from approximately $125 million in 1995 to approximately $2.0 billion in 2010. We believe the water industry is structurally attractive as a result of a growing demand for clean water and the large global market size. Our vision is to be a leading global provider of innovative products and systems used in the movement, storage, treatment and enjoyment of water.

Our Technical Products Group operates in a large global market with significant potential for growth in industry segments such as data communications, industrial, infrastructure and energy. We believe we have the largest industrial and commercial distribution network in North America for enclosures and the highest brand recognition in the industry in North America.

On May 12, 2011, we acquired as part of our Water Group the Clean Process Technologies (“CPT”) division of privately held Norit Holding B.V. for $715.3 million (€502.7 million translated at the May 12, 2011 exchange rate). CPT’s results of operations have been included in our consolidated financial statements since the date of acquisition. CPT is a global leader in membrane solutions and clean process technologies in the high growth water and beverage filtration and separation segments. CPT provides sustainable purification systems and solutions for desalination, water reuse, industrial applications and beverage segments that effectively address the increasing challenges of clean water scarcity, rising energy costs and pollution. CPT’s product offerings include innovative ultrafiltration and nanofiltration membrane technologies, aseptic valves, CO₂ recovery and control systems and specialty pumping equipment. Based in the Netherlands, CPT has broad sales diversity with the majority of 2010 revenues generated in European Union countries and Asia-Pacific.

The fair value of the business acquired was allocated to the assets acquired and liabilities assumed based on their estimated fair values. The excess of the fair value acquired over the identifiable assets acquired and liabilities assumed is reflected as goodwill. Goodwill recorded as part of the purchase price allocation was $451.8 million, none of which is tax deductible. Identifiable intangible assets acquired as part of the acquisition were $197.2 million, including definite-lived intangibles, such as customer relationships, proprietary technology and trade names with a weighted average amortization period of approximately 10 years.

On January 31, 2011 we acquired as part of our Water Group all of the outstanding shares of capital stock of Hidro Filtros do Brasil (“Hidro Filtros”) for cash of $14.9 million and a note payable of $2.1 million. The Hidro Filtros results of operations have been included in our consolidated financial statements since the date of acquisition. Hidro Filtros is a leading manufacturer of water filters and filtering elements for residential and industrial applications operating in Brazil and neighboring countries. Goodwill recorded as part of the purchase price allocation was $10.1 million, none of which is tax deductible. Identified intangible assets acquired as part of the acquisition were $6.3 million including definite-lived intangibles, primarily customer relationships, of $5.5 million with an estimated life of 13 years.

Additionally, during the first six months of 2011, we completed other small acquisitions with purchase prices totaling $4.6 million, consisting of $2.9 million in cash and $1.7 million as a note payable, adding to our Water Group. Total goodwill recorded as part of the purchase price allocation was $4.3 million, none of which is tax deductible.

Key Trends and Uncertainties

The following trends and uncertainties affected our financial performance in 2010 and the first six months of 2011 and will likely impact our results in the future:

• Most markets we serve slowed dramatically in late 2008 and throughout 2009 as a result of the global recession. In 2010 and the first six months of 2011, most markets showed signs of improvement. Because our businesses are significantly affected by general economic trends, a lack of continued improvement in our most important markets addressed below would likely have an adverse impact on our results of operation for the remainder of 2011 and beyond.

• We have also identified specific market opportunities that we continue to pursue that we find attractive, both within and outside the United States. We are reinforcing our businesses to more effectively address these opportunities through research and

26

development and additional sales and marketing resources. Unless we successfully penetrate these product and geographic markets, our organic growth would likely be limited.

• After four years of new home building and new pool start contraction in the United States, these end markets stabilized in 2010 and the first six months of 2011. Overall, we believe approximately 40% of Pentair sales are used in global residential applications – for replacement and refurbishment, remodeling and repair and new construction. We expect this stabilization, along with new product introductions, expanded distribution and channel penetration, to result in volume increases for the remainder of 2011. We believe that housing construction and new pool starts will modestly lag in 2011, but our participation in this trend historically has lagged approximately six months from inception.

• Industrial, communications and commercial markets for all of our businesses, including commercial and industrial construction, also slowed significantly in 2009. Order rates and sales improved in our industrial and communications businesses in 2010 and the first six months of 2011 as business spending returned, while non-residential construction markets still declined. We believe that the outlook for most of these markets is mixed and we expect that non-residential construction declines will moderate compared to 2010.

• Through 2010 and the first six months of 2011, we experienced material and other cost inflation. We strive for productivity improvements, and we implement increases in selling prices to mitigate this inflation. We expect the current economic environment will result in continuing price volatility for many of our raw materials. We believe that the impact of higher commodity prices will continue to impact us for the remainder of 2011, but we are uncertain on the timing and impact of this cost inflation.

• Despite higher interest expense and lower discount rates, our unfunded pension liabilities declined to approximately $201 million as of the end of 2010 due to investment performance and plan contributions. The contributions included accelerated contributions of $25 million in December 2009 and 2010, respectively, to improve plan balances and reduce future contributions.

• We have a long-term goal to consistently generate free cash flow that equals or exceeds 100 percent of our net income. We define free cash flow as cash flow from continuing operating activities less capital expenditures plus proceeds from sale of property and equipment. Free cash flow for the full year 2010 was approximately $211 million, or 106% of our net income. We continue to expect to generate free cash flow in excess of net income from continuing operations in 2011. We are continuing to target reductions in working capital and particularly inventory, as a percentage of sales. See our discussion of Other financial measures under the caption “Liquidity and Capital Resources” in this report for a reconciliation of our free cash flow.

In 2011, our operating objectives include the following:

• Increasing our presence in fast growth regions and vertical market focus to grow in those markets in which we have competitive advantages;

• Leveraging our technological capabilities to increasingly generate innovative new products;

• Driving operating excellence through lean enterprise initiatives, with specific focus on sourcing and supply management, cash flow management and lean operations; and

• Focusing on proactive talent development, particularly in international management and other key functional areas.

We may seek to meet our objectives of expanding our geographic reach internationally, expanding our presence in our various channels to market and acquiring technologies and products to broaden our businesses’ capabilities to serve additional markets through acquisitions. We may also consider the divestiture of discrete business units to further focus our businesses on their most attractive markets.

Total		15.1		12.7		14.3		11.7		16.2		13.1

Consolidated net sales

The 14.3 and 13.1 percentage point increases in consolidated net sales in the second quarter and first half, respectively, of 2011 from 2010 were primarily driven by:

• higher sales volume related to the May 2011 acquisition of CPT;

• favorable foreign currency effects;

• higher sales of certain pump, pool and filtration products primarily related to the stabilization in the North American and Western European residential housing markets and other global markets;

• higher sales volumes in the Technical Products Group; and

• selective increases in selling prices to mitigate inflationary cost increases.

Net sales by segment and the change from prior year period were as follows:

	Three months ended									Six months ended
In thousands	July 2, 2011		July 3, 2010		$ change		% change			July 2, 2011		July 3, 2010		$ change		% change

Water Group

The 15.1 and 11.7 percentage point increase in Water Group net sales in the second quarter and first half, respectively of 2011 from 2010 was primarily driven by:

• higher sales volume related to the May 2011 acquisition of CPT;

• organic sales growth for the second quarter and first half of 2011 primarily due to higher sales of certain pump, pool and filtration products primarily related to the stabilization in the North American and Western European residential housing markets and other global markets;

28

• continued sales growth in emerging markets particularly in the Middle East, Latin America and China;

• favorable foreign currency effects; and

• selective increases in selling prices to mitigate inflationary cost increases.

Technical Products Group

The 12.7 and 16.2 percentage point increases in Technical Product Group net sales in the second quarter and first half, respectively, of 2011 from 2010 were primarily driven by:

• an increase in sales volume in industrial, general electronics and energy vertical markets;

• favorable foreign currency effects; and

• selective increases in selling prices to mitigate inflationary cost increases.

Gross Profit

	Three months ended										Six months ended
In thousands	July 2, 2011		% of sales			July 3, 2010		% of sales			July 2, 2011		% of sales			July 3, 2010		% of sales
Gross Profit	$	287,736		31.6	%	$	248,168		31.2	%	$	536,795		31.6	%	$	461,870		30.7	%
Percentage point change				0.4 pts										0.9 pts

The 0.4 and 0.9 percentage point increases in gross profit as a percentage of sales in the second quarter and first half, respectively, of 2011 from 2010 were primarily the result of:

• higher sales volumes in our Water and Technical Products Groups and higher fixed cost absorption resulting from that volume;

• savings generated from our Pentair Integrated Management System (“PIMS”) initiatives including lean and supply management practices; and

• selective increases in selling prices in our Water and Technical Products Groups to mitigate inflationary cost increases.

These increases were partially offset by:

• inflationary increases related to raw materials and labor costs; and

• higher cost of goods sold in 2011 as a result of the inventory fair market value step-up and customer backlog recorded as part of the CPT purchase accounting.

Selling, general and administrative (SG&A)

	Three months ended										Six months ended
In thousands	July 2, 2011		% of sales			July 3, 2010		% of sales			July 2, 2011		% of sales			July 3, 2010		% of sales

Percentage point change				0.9 pts										0.2 pts

The 0.9 and 0.2 percentage point increases in SG&A expense as a percentage of sales in the second quarter and first half, respectively, of 2011 from 2010 were primarily due to:

• higher costs associated with the integration and intangible amortization related to the May 2011 acquisition of CPT;

• insurance proceeds related to the Horizon litigation received in the second quarter of 2010;

• continued investments in future growth with emphasis on growth in international markets, including personnel and business infrastructure investments; and

• certain increases for labor and related costs.

These increases were partially offset by:

• higher sales volumes in both our Water and Technical Products Groups, which resulted in increased leverage on the fixed operating expenses.

The 0.1 percentage point increase in R&D expense as a percentage of sales in each of the second quarter and first half of 2011 from 2010 was primarily due to:

• higher costs associated with the May 2011 acquisition of CPT; and

• continued investments in the development of new products to generate growth.

These increases were partially offset by:

• higher sales volumes in both our Water and Technical Products Groups, which resulted in increased leverage on the fixed cost operating expenses.

The 0.4 percentage point decrease in Water segment operating income as a percentage of net sales in the second quarter of 2011 as compared to 2010 was primarily the result of:

• higher cost of goods sold in 2011 as a result of the inventory fair market value step-up and customer backlog recorded as part of the CPT purchase accounting;

• higher costs associated with the integration and intangible amortization related to the May 2011 acquisition of CPT;

• cost increases for certain raw materials and labor;

• insurance proceeds related to the Horizon litigation received in the second quarter of 2010; and

• continued investment in future growth with emphasis on growth in international markets, including personnel and business infrastructure investments.

These decreases were offset by:

• higher sales volume in our Water Group, which resulted in increased leverage of the fixed cost base;

• savings generated from our PIMS initiatives including lean and supply management practices; and

• selective increases in selling prices to mitigate inflationary cost increases.

The 0.8 percentage point increase in Water segment operating income as a percentage of net sales in the first half of 2011 as compared to 2010 was primarily the result of:

The 70.5 and 32.3 percentage point increases in interest expense in the second quarter and first half, respectively, of 2011 from 2010 were primarily the result of:

• certain discrete items in the first half of 2011 that did not occur in 2010; and

• the mix of global earnings, including the impact of the CPT acquisition.

LIQUIDITY AND CAPITAL RESOURCES

We generally fund cash requirements for working capital, capital expenditures, equity investments, acquisitions, debt repayments, dividend payments and share repurchases from cash generated from operations, availability under existing committed revolving credit facilities and in certain instances, public and private debt and equity offerings. We have grown our businesses in significant part in the past through acquisitions financed by credit provided under our revolving credit facilities and from time to time, by private or public debt issuance. Our primary revolving credit facilities have generally been adequate for these purposes, although we have negotiated additional credit facilities as needed to allow us to complete acquisitions.

We are focusing on increasing our cash flow and repaying existing debt, while continuing to fund our research and development, marketing and capital investment initiatives. Our intent is to maintain investment grade ratings and a solid liquidity position.

We experience seasonal cash flows primarily due to seasonal demand in a number of markets within our Water Group. We generally borrow in the first quarter of our fiscal year for operational purposes, which usage reverses in the second quarter as the seasonality of our businesses peaks. End-user demand for pool and certain pumping equipment follows warm weather trends and is at seasonal highs from April to August. The magnitude of the sales spike is partially mitigated by employing some advance sale “early buy” programs (generally including extended payment terms and/or additional discounts). Demand for residential and agricultural water systems is also impacted by weather patterns, particularly by heavy flooding and droughts.

32

Operating activities

Cash provided by operating activities was $152.6 million in the first six months of 2011 compared to $156.4 million in the prior year comparable period 2010. The decrease in cash provided by operating activities was due primarily to an increase in working capital, partially offset by an increase in income from continuing operations.

Investing activities

Capital expenditures in the first six months of 2011 were $35.2 million compared with $28.9 million in the prior year period. We currently anticipate capital expenditures for fiscal 2011 will be approximately $60 million to $70 million, primarily for capacity expansions in our key growth markets, new product development, and replacement equipment.

On January 31, 2011 we acquired as part of our Water Group all of the outstanding shares of capital stock of Hidro Filtros for cash of $14.9 million and a note payable of $2.1 million.

On May 12, 2011, we acquired as part of our Water Group the CPT division, from privately held Norit Holding for $715.3 million.

Additionally, during the first six months of 2011, we completed other small acquisitions with purchase prices totaling $4.6 million, consisting of $2.9 million in cash and $1.7 million as a note payable, adding to our Water Group.

Financing activities

Net cash provided by financing activities was $638.3 million in the first six months of 2011 compared with cash used for financing activities of $105.9 million in the prior year period. The increase primarily relates to borrowing utilized to fund the CPT acquisition. Additionally, financing activities included draw downs and repayments on our revolving credit facilities to fund our operations in the normal course of business, payments of dividends, cash received/used for stock issued to employees and tax benefits related to stock-based compensation.

On April 28, 2011, we entered into a Fourth Amended and Restated Credit Agreement (the “Credit Facility”). The Credit Facility replaced our previous $800 million revolving credit facility. The Credit Facility creates an unsecured, committed credit facility of up to $700 million, with multi-currency sub-facilities to support investments outside the U.S. The Credit Facility expires on April 28, 2016. Borrowings under the Credit Facility currently bear interest at the rate of London Interbank Offered Rate (“LIBOR”) plus 1.75%. Interest rates and fees on the Credit Facility will vary based on our credit ratings. We used borrowings under the Credit Facility to fund a portion of the CPT acquisition and to fund ongoing operations.

We are authorized to sell short-term commercial paper notes to the extent availability exists under the Credit Facility. We use the Credit Facility as back-up liquidity to support 100% of commercial paper outstanding. Our use of commercial paper as a funding vehicle depends upon the relative interest rates for our commercial paper compared to the cost of borrowing under our Credit Facility. As of July 2, 2011, we had no commercial paper outstanding.

Total availability under our existing Credit Facility was $437.9 million as of July 2, 2011, which was not limited by any of the credit agreement’s financial covenants as of that date.

Our debt agreements contain certain financial covenants, the most restrictive of which is a leverage ratio (total consolidated indebtedness, as defined, over consolidated net income before interest, taxes, depreciation, amortization and non-cash compensation expense (“EBITDA”), as defined) that may not exceed 4.0 to 1.0 as of July 2, 2011, 3.75 to 1.0 as of October 1, 2011, and 3.5 to 1.0 as of the last date of each of our fiscal quarters thereafter.

We were in compliance with all financial covenants in our debt agreements as of July 2, 2011.

In addition to the Credit Facility, we have $40.0 million and $39.2 million (€27.0 million translated at the July 2, 2011 exchange rate) of other credit facilities, of which $21.8 (€15.0 million translated at the July 2, 2011 exchange rate) is committed until April 2016. Borrowings under these credit facilities bear interest at the rates of Euro Interbank Offered Rate (“Euribor”) plus 1.5% to 1.75%. We had $3.4 million and $18.0 million (€12.4 million translated at the July 2, 2011 exchange rate) of borrowings under these credit facilities as of July 2, 2011. Additionally, as part of the CPT acquisition we assumed certain capital leases with an outstanding balance of $18.3 million at July 2, 2011.

33

We have $105 million of outstanding private placement debt maturing in May 2012. We classified this debt as long-term as of July 2, 2011 as we have the intent and ability to refinance such obligation on a long-term basis under the Credit Facility.

Our cost of and ability to obtain debt financing may be impacted by our credit ratings. Our long-term debt is rated at BBB- by Standard & Poor’s (“S&P”) with stable outlook and Baa3 by Moody’s with stable outlook.

We issue short-term commercial paper notes that are currently not rated by S&P or Moody’s. Even though our short-term commercial paper is unrated, we believe a downgrade in our credit rating could have a negative impact on our ability to continue to issue unrated commercial paper.

We do not expect that a one rating downgrade of our credit rating by either S&P or Moody’s would substantially affect our ability to access the long-term debt capital markets. However, depending upon market conditions, the amount, timing and pricing of new borrowings and interest rates under our Credit Facility could be adversely affected. If both of our credit ratings were downgraded to below BBB-/Baa3, our flexibility to access the term debt capital markets would be reduced.

A credit rating is a current opinion of the creditworthiness of an obligor with respect to a specific financial obligation, a specific class of financial obligations or a specific financial program. The credit rating takes into consideration the creditworthiness of guarantors, insurers or other forms of credit enhancement on the obligation and takes into account the currency in which the obligation is denominated. The ratings outlook also highlights the potential direction of a short or long-term rating. It focuses on identifiable events and short-term trends that cause ratings to be placed under observation by the respective rating agencies. A change in rating outlook does not mean a rating change is inevitable.

We expect to continue to have cash requirements to support working capital needs and capital expenditures, to pay interest and service debt and to pay dividends to shareholders annually. We believe we have the ability and sufficient capacity to meet these cash requirements, by using available cash and internally generated funds and to borrow under our committed and uncommitted credit facilities.

Dividends paid in the first six months of 2011 were $39.7 million, or $0.20 per common share, compared with $37.7 million, or $0.19 per common share, in the prior year period. We have increased dividends every year for the last 35 years and expect to continue paying dividends on a quarterly basis.

The total gross liability for uncertain tax positions was $24.8 million, $24.3 million and $27.9 million at July 2, 2011, December 31, 2010 and July 3, 2010, respectively. We are not able to reasonably estimate the amount by which the estimate will increase or decrease over time; however, at this time, we do not expect a significant payment related to these obligations within the next twelve months.

Other financial measures

In addition to measuring our cash flow generation or usage based upon operating, investing and financing classifications included in the Condensed Consolidated Statements of Cash Flows, we also measure our free cash flow. We have a long-term goal to consistently generate free cash flow that equals or exceeds 100% conversion of net income from continuing operations. Free cash flow is a non-Generally Accepted Accounting Principles financial measure that we use to assess our cash flow performance. We believe free cash flow is an important measure of operating performance because it provides us and our investors a measurement of cash generated from operations that is available to pay dividends, make acquisitions, repay debt and repurchase shares. In addition, free cash flow is used as a criterion to measure and pay compensation-based incentives. Our measure of free cash flow may not be comparable to similarly titled measures reported by other companies. The following table is a reconciliation of free cash flow:

	Six months ended
In thousands	July 2, 2011			July 3, 2010

PART II OTHER INFORMATION

ITEM 1. Legal Proceedings

There have been no further material developments from the disclosures contained in our 2010 Annual Report on Form 10-K.

ITEM 1A. Risk Factors

The following risk factors amend and supersede the risk factors previously disclosed in Item 1A to our Annual Report on Form 10-K for the year ended December 31, 2010.

You should carefully consider the following risk factors and warnings before making an investment decision. You are cautioned not to place undue reliance on any forward-looking statements. If any of the risks described below actually occur, our business, financial condition, results of operations or prospects could be materially adversely affected. In that case, the price of our securities could decline and you could lose all or part of your investment. You should also refer to other information set forth in this document.

We may not realize the anticipated benefits of the CPT acquisition and any benefit may take longer to realize than we expect.

The CPT acquisition involves the integration of CPT’s operations with our existing operations, and there are uncertainties inherent in such an integration. We will be required to devote significant management attention and resources to integrating CPT’s operations. Delays or unexpected difficulties in the integration process could adversely affect our business, financial results and financial condition. Even if we are able to integrate CPT’s operations successfully, this integration may not result in the realization of the full benefits of revenue synergies, cost savings and operational efficiencies that we expect or the achievement of these benefits within a reasonable period of time. In addition, we may have not discovered during the due diligence process all known and unknown factors regarding CPT that could produce unintended and unexpected consequences for us. Undiscovered factors could result in us incurring financial liabilities, which could be material, and in us not achieving the expected benefits from the CPT acquisition within our desired time frames, if at all.

Increased leverage may harm our financial condition and results of operations.

As of July 2, 2011, we had $1,406.9 million of total debt on a consolidated basis. We increased our indebtedness materially in connection with our acquisition of CPT. We and our subsidiaries may incur additional indebtedness in the future. This increase and any future increase in our level of indebtedness will have several important effects on our future operations, including, without limitation:

• we will have additional cash requirements in order to support the payment of interest on our outstanding indebtedness;

• increases in our outstanding indebtedness and leverage may increase our vulnerability to adverse changes in general economic and industry conditions, as well as to competitive pressure;

• our ability to obtain additional financing for working capital, capital expenditures, general corporate and other purposes may be reduced;

• our flexibility in planning for, or reacting to, changes in our business and our industry may be reduced; and

• our flexibility to make acquisitions and develop technology may be limited.

Our ability to make payments of principal and interest on our indebtedness depends upon our future performance, which will be subject to general economic conditions and financial, business and other factors affecting our consolidated operations, many of which are beyond our control. If we are unable to generate sufficient cash flow from operations in the future to service our debt and meet our other cash requirements, we may be required, among other things:

• to seek additional financing in the debt or equity markets;

• to refinance or restructure all or a portion of our indebtedness;

• to sell selected assets or businesses; or

• to reduce or delay planned capital or operating expenditures.

36

Such measures might not be sufficient to enable us to service our debt and meet our other cash requirements. In addition, any such financing, refinancing or sale of assets might not be available at all or on economically favorable terms.

General economic conditions, including difficult credit and residential construction markets, affect demand for our products.

We compete around the world in various geographic regions and product markets. Among these, the most significant are global industrial markets (for both the Technical Products and Water Groups) and residential markets (for the Water Group). Important factors for our businesses include the overall strength of the economy and our customers’ confidence in the economy; industrial and governmental capital spending; the strength of the residential and commercial real estate markets; unemployment rates; availability of consumer and commercial financing for our customers and end-users; and interest rates. New construction for residential housing and home improvement activity fell in 2007, 2008 and 2009, which reduced revenue growth in the residential businesses within our Water Group. While we saw some stabilization in 2010 and the first half of 2011, we believe that weakness in this market could negatively impact our revenues and margins in future periods. Further, while we attempt to minimize our exposure to economic or market fluctuations by serving a balanced mix of end markets and geographic regions, we cannot assure you that a significant or sustained downturn in a specific end market or geographic region would not have a material adverse effect on us.

Our inability to sustain organic growth could adversely affect our financial performance.

Over the past five years, our organic growth has been generated in part from expanding international sales, entering new distribution channels, introducing new products and price increases. To grow more rapidly than our end markets, we would have to continue to expand our geographic reach, further diversify our distribution channels, continue to introduce new products and increase sales of existing products to our customer base. Difficult economic and competitive factors materially and adversely impacted our financial performance in 2009. These conditions started to improve in many of our end markets in 2010 and the first half of 2011, but we cannot assure you that these markets will continue to improve nor that we will be able to increase revenues and profitability to match our earlier financial performance. We have chosen to focus our growth initiatives in specific end markets and geographies. We cannot assure you that these growth initiatives will be sufficient to offset revenue declines in other markets.

Our businesses operate in highly competitive markets, so we may be forced to cut prices or to incur additional costs.

Our businesses generally face substantial competition in each of their respective markets. Competition may force us to cut prices or to incur additional costs to remain competitive. We compete on the basis of product design, quality, availability, performance, customer service and price. Present or future competitors may have greater financial, technical or other resources which could put us at a disadvantage in the affected business or businesses. We cannot assure you that these and other factors will not have a material adverse effect on our future results of operations.

Material cost and other inflation have adversely affected and could continue to affect our results of operations.

In the past, we have experienced material cost and other inflation in a number of our businesses. We strive for productivity improvements and implement increases in selling prices to help mitigate cost increases in raw materials (especially metals and resins), energy and other costs such as pension, health care and insurance. We continue to implement our excellence in operations initiatives in order to mitigate the impacts of this inflation and continuously reduce our costs. We cannot assure you, however, that these actions will be successful in managing our costs or increasing our productivity. Continued cost inflation or failure of our initiatives to generate cost savings or improve productivity would likely negatively impact our results of operations.

We are exposed to political, economic and other risks that arise from operating a multinational business.

Sales outside of the United States, including export sales from our domestic businesses, accounted for approximately 34% of our net sales in both 2010 and 2009. Our sales outside of the United States will increase materially as a result of the CPT acquisition. Further, most of our businesses obtain some products, components and raw materials from foreign suppliers. Accordingly, our business is subject to the political, economic and other risks that are inherent in operating in numerous countries. These risks include:

• changes in general economic and political conditions in countries where we operate, particularly in emerging markets;

• relatively more severe economic conditions in some international markets than in the United States;

• the difficulty of enforcing agreements and collecting receivables through foreign legal systems;

37

• trade protection measures and import or export licensing requirements;

• the possibility of terrorist action against us or our operations;

• the imposition of tariffs, exchange controls or other trade restrictions;

• difficulty in staffing and managing widespread operations in non-U.S. labor markets;

• changes in tax laws or rulings could have an adverse impact on our effective tax rate;

• the difficulty of protecting intellectual property in foreign countries; and

• required compliance with a variety of foreign laws and regulations.

As a result of our international operations and sales, we are subject to the Foreign Corrupt Practice Act (“FCPA”) and other laws that prohibit improper payments or offers of payments to foreign governments and their officials for the purpose of obtaining or retaining business. Our international activities create the risk of unauthorized payments or offers of payments in violation of the FCPA by one of our employees, consultants, sales agents or distributors, because these parties are not always subject to our control. Any violations of the FCPA could result in significant fines, criminal sanctions against us or our employees, and prohibitions on the conduct of our business, including our business with the U.S. government. In addition, prior to our acquisition of CPT, CPT previously conducted business in countries that are subject to economic sanctions by the U.S. government. To the extent these sanctions prohibit CPT from selling its products in such countries after our acquisition of CPT, CPT may have reduced revenues and we could be subject to liability for not being able to fulfill contracts CPT entered into prior to its acquisition by us.

Our business success depends in part on our ability to anticipate and effectively manage these and other risks. We cannot assure you that these and other factors will not have a material adverse effect on our international operations or on our business as a whole.

Our international operations are subject to foreign market and currency fluctuation risks.

We expect the percentage of our sales outside of the United States to increase in the future, including due to the completion of the CPT acquisition. Over the past few years, the economies of some of the foreign countries in which we do business have had slower growth than the U.S. economy. The European Union currently accounts for the majority of our foreign sales and income, in which our most significant European market is Germany, and we expect it to continue to do so after our acquisition of CPT. In addition, we have a significant and growing business in the Asia-Pacific region, but the economic conditions in countries in this region are subject to different growth expectations, market weaknesses and business practices. We cannot predict how changing market conditions in these regions will impact our financial results.

We are also exposed to the risk of fluctuation of foreign currency exchange rates which may affect our financial results as we manufacture and source certain products, components and raw materials throughout the world.

We have significant goodwill and intangible assets and future impairment of our goodwill and intangible assets could have a material negative impact on our financial results.

We test goodwill and indefinite-lived intangible assets for impairment on an annual basis, by comparing the estimated fair value of each of our reporting units to their respective carrying values on their balance sheets. At July 2, 2011 our goodwill and intangible assets were approximately $3,228.3 million and represented approximately 63.9% of our total assets. Long-term declines in projected future cash flows could result in future goodwill and intangible asset impairments. Because of the significance of our goodwill and intangible assets, any future impairment of these assets could have a material adverse effect on our financial results.

Seasonality of sales and weather conditions may adversely affect our financial results.

We experience seasonal demand in a number of markets within our Water Group. End-user demand for pool equipment in our primary markets follows warm weather trends and is at seasonal highs from April to August. The magnitude of the sales increase is partially mitigated by employing some advance sale or “early buy” programs (generally including extended payment terms and/or additional discounts). Demand for residential and agricultural water systems is also impacted by weather patterns, particularly by heavy flooding and droughts. We cannot assure you that seasonality and weather conditions will not have a material adverse effect on our results of operations.

38

Intellectual property challenges may hinder product development and marketing.

Patents, non-compete agreements, proprietary technologies, customer relationships, trade marks, trade names and brand names are important to our business. Intellectual property protection, however, may not preclude competitors from developing products similar to ours or from challenging our names or products. Over the past few years, we have noticed an increasing tendency for participants in our markets to use conflicts over and challenges to intellectual property as a means to compete. Patent and trademark challenges increase our costs to develop, engineer and market our products.

Our results of operations may be negatively impacted by litigation.

Our businesses expose us to potential litigation, such as product liability claims relating to the design, manufacture and sale of our products. While we currently maintain what we believe to be suitable product liability insurance, we cannot assure you that we will be able to maintain this insurance on acceptable terms or that this insurance will provide adequate protection against potential liabilities. In addition, we self-insure a portion of product liability claims. A series of successful claims against us for significant amounts could materially and adversely affect our product reputation, financial condition, results of operations and cash flows.

We may not be able to expand through acquisitions and acquisitions we complete may adversely affect our financial performance.

We intend to continue to evaluate strategic acquisitions primarily in our current business segments, though we may consider acquisitions outside of these segments as well. Our ability to expand through acquisitions is subject to various risks, including the following:

• Limitations on pursuing acquisitions due to increased leverage as a result of the CPT acquisition;

• Higher acquisition prices;

• Lack of suitable acquisition candidates in targeted product or market areas;

• Increased competition for acquisitions, especially in the water industry;

• Inability to integrate acquired businesses effectively or profitably; and

• Inability to achieve anticipated synergies or other benefits from acquisitions.

Acquisitions we may undertake could have a material adverse effect on our operating results, particularly in the fiscal quarters immediately following the acquisitions, while we attempt to integrate operations of the acquired businesses into our operations. Once integrated, acquired operations may not achieve the levels of financial performance originally anticipated.

The availability and cost of capital could have a negative impact on our financial performance.

Our plans to vigorously compete in our chosen markets will require additional capital for future acquisitions, capital expenditures, growth of working capital and continued international and regional expansion. In the past, we have financed growth of our businesses primarily through cash from operations and debt financing. While we refinanced our primary credit agreements in 2011 on what we believe to be favorable terms, future acquisitions or other uses of funds may require us to expand our debt financing resources or to issue equity securities. Our financial results may be adversely affected if new financing is not available on favorable terms or if interest costs under our debt financings are higher than the income generated by acquisitions or other internal growth. In addition, future share issuances could be dilutive to your equity investment if we sell shares into the market or issue additional stock as consideration in any acquisition. We cannot assure you that we will be able to issue equity securities or obtain future debt financing at favorable terms. Without sufficient financing, we will not be able to pursue our targeted growth strategy and our acquisition program, which may limit our revenue growth and future financial performance.

We are exposed to potential environmental and other laws, liabilities and litigation.

We are subject to federal, state, local and foreign laws and regulations governing our environmental practices, public and worker health and safety and the indoor and outdoor environment. Compliance with these environmental, health and safety regulations could require us to satisfy environmental liabilities, increase the cost of manufacturing our products or otherwise adversely affect our business, financial condition and results of operations. Any violations of these laws by us could cause us to incur unanticipated liabilities that could harm our operating results and cause our business to suffer. We are also required to comply with various

39

environmental laws and maintain permits, some of which are subject to discretionary renewal from time to time, for many of our businesses and we could suffer if we are unable to renew existing permits or to obtain any additional permits that we may require.

We have been named as defendants, targets or potentially responsible parties (“PRP”) in a number of environmental clean-ups relating to our current or former business units. We have disposed of a number of businesses in recent years and in certain cases, we have retained responsibility and potential liability for certain environmental obligations. We have received claims for indemnification from certain purchasers. We may be named as a PRP at other sites in the future for existing business units, as well as both divested and acquired businesses.

We cannot ensure you that environmental requirements will not change or become more stringent over time or that our eventual environmental clean-up costs and liabilities will not exceed the amount of our current reserves.

We are exposed to certain regulatory and financial risks related to climate change.

Climate change is receiving ever increasing attention worldwide. Many scientists, legislators and others attribute global warming to increased levels of greenhouse gases, including carbon dioxide, which has led to significant legislative and regulatory efforts to limit greenhouse gas emissions. The U.S. Congress and federal and state regulatory agencies have been considering legislation and regulatory proposals that would regulate and limit greenhouse gas emissions. It is uncertain whether, when and in what form a federal mandatory carbon dioxide emissions reduction program may be adopted. Similarly, certain countries have adopted the Kyoto Protocol and this and other international initiatives under consideration could affect our international operations. These actions could increase costs associated with our operations, including costs for raw materials and transportation. Because it is uncertain what laws will be enacted, we cannot predict the potential impact of such laws on our future consolidated financial condition, results of operations or cash flows.

Stock-based Compensation

6 Months Ended

Stock-based Compensation

3. Stock-based Compensation

Total stock-based compensation expense was $4.8 million and $5.6 million for the three months ended July 2, 2011 and July 3, 2010, respectively, and was $10.5 million and $12.4 million for the six months ended July 2, 2011 and July 3, 2010, respectively.

During the first half of 2011, restricted shares and restricted stock units of our common stock were granted under the 2008 Omnibus Stock Incentive Plan to eligible employees with a vesting period of three to four years after issuance. Restricted share awards and restricted stock units are valued at market value on the date of grant and are typically expensed over the vesting period. Total compensation expense for restricted share awards and restricted stock units was $2.5 million and $2.8 million for the three months ended July 2, 2011 and July 3, 2010, respectively, and was $5.8 million and $6.5 million for the six months ended July 2, 2011 and July 3, 2010, respectively.

During the first half of 2011, option awards were granted under the 2008 Omnibus Stock Incentive Plan with an exercise price equal to the market price of our common stock on the date of grant. Option awards are typically expensed over the vesting period. Total compensation expense for stock option awards was $2.3 million and $2.8 million for the three months ended July 2, 2011 and July 3, 2010, respectively, and $4.7 million and $5.9 million for the six months ended July 2, 2011 and July 3, 2010, respectively.

We estimated the fair value of each stock option award on the date of grant using a Black-Scholes option pricing model, modified for dividends and using the following assumptions:

	July 2, 2011			July 3, 2010
Expected stock price volatility		35.5	%		35.0	%
Expected life		5.5 yrs			5.5 yrs
Risk-free interest rate		2.12	%		2.25	%
Dividend yield		2.16	%		2.20	%

The weighted-average fair value of options granted during the second quarter of 2011 and 2010 were $10.89 and $9.80 per share, respectively.

These estimates require us to make assumptions based on historical results, observance of trends in our stock price, changes in option exercise behavior, future expectations and other relevant factors. If other assumptions had been used, stock-based compensation expense, as calculated and recorded under the accounting guidance could have been affected.

We based the expected life assumption on historical experience as well as the terms and vesting periods of the options granted. For purposes of determining expected volatility, we considered a rolling average of historical volatility measured over a period approximately equal to the expected option term. The risk-free rate for periods that coincide with the expected life of the options is based on the U.S. Treasury Department yield curve in effect at the time of grant.

Acquisitions

6. Acquisitions

On May 12, 2011, we acquired as part of our Water Group the Clean Process Technologies (“CPT”) division of privately held Norit Holding B.V. for $715.3 million (€502.7 million translated at the May 12, 2011 exchange rate). CPT’s results of operations have been included in our consolidated financial statements since the date of acquisition. CPT is a global leader in membrane solutions and clean process technologies and significantly expands our position in the high growth water and beverage filtration and separation segments. CPT provides sustainable purification systems and solutions for desalination, water reuse, industrial applications and beverage segments that effectively address the increasing challenges of clean water scarcity, rising energy costs and pollution. CPT’s product offerings include innovative ultrafiltration and nanofiltration membrane technologies, aseptic valves, CO₂ recovery and control systems and specialty pumping equipment. Based in the Netherlands, CPT has broad sales diversity with the majority of 2010 revenues generated in European Union countries and Asia-Pacific

The fair value of the business acquired was allocated to the assets acquired and liabilities assumed based on their estimated fair values. The excess of the fair value acquired over the identifiable assets acquired and liabilities assumed is reflected as goodwill. Goodwill recorded as part of the purchase price allocation was $451.8 million, none of which is tax deductible. Identifiable intangible assets acquired as part of the acquisition were $197.2 million, including definite-lived intangibles, such as customer relationships, proprietary technology and trade names with a weighted average amortization period of approximately 10 years.

The CPT business records certain long term contracts under the percentage-of-completion method of accounting. Under this method, sales and gross profit are recognized as work is performed based on the relationship between actual costs incurred and total estimated costs at completion. We record costs and earnings in excess of billings on uncompleted contracts within Prepaid expenses and other current assets and billings in excess of costs and earnings on uncompleted contracts within Other current liabilities in the Condensed Consolidated Balance Sheets. Amounts included in Prepaid expenses and other current assets related to these contracts were $40.4 million at July 2, 2011. Amounts included in Other current liabilities related to these contracts were $11.3 million at July 2, 2011.

The total purchase price has been allocated to the estimated fair values of assets acquired and liabilities assumed as follows:

(in thousands)
Accounts and notes receivable	$	70,038
Inventories		60,382
Deferred tax assets		4,926
Prepaid expenses and other current assets		40,252

These pro forma condensed consolidated financial results have been prepared for comparative purposes only and include certain adjustments, such as increased interest expense on acquisition debt. They do not reflect the effect of costs or synergies that would have been expected to result from the integration of the acquisition. The pro forma information does not purport to be indicative of the results of operations that actually would have resulted had the combination occurred at the beginning of each period presented, or of future results of the consolidated entities.

On January 31, 2011 we acquired as part of our Water Group all of the outstanding shares of capital stock of Hidro Filtros do Brasil (“Hidro Filtros”) for cash of $14.9 million and a note payable of $2.1 million. The Hidro Filtros results of operations have been included in our consolidated financial statements since the date of acquisition. Hidro Filtros is a leading manufacturer of water filters and filtering elements for residential and industrial applications operating in Brazil and neighboring countries. Goodwill recorded as part of the purchase price allocation was $10.1 million, none of which is tax deductible. Identified intangible assets acquired as part of the acquisition were $6.3 million including definite-lived intangibles, primarily customer relationships, of $5.5 million with an estimated life of 13 years. The proforma impact of this acquisition was deemed to be not material.

Additionally, during the first six months of 2011, we completed other small acquisitions with purchase prices totaling $4.6 million, consisting of $2.9 million in cash and $1.7 million as a note payable, adding to our Water Group. Total goodwill recorded as part of the purchase price allocation was $4.3 million, none of which is tax deductible. The proforma impact of these acquisitions was deemed to be not material.

Total transaction costs related to acquisition activities for the six months ended July 2, 2011 were $7.8 million, which were expensed as incurred and recorded in Selling, general and administrative in our Condensed Consolidated Statements of Income.

Long-term debt						$	1,384,167		$	702,521		$	734,472

The fair value of total debt excluding the deferred gain on interest rate swaps, was $1,440.1 million, $745.9 million and $772.6 million as of July 2, 2011, December 31, 2010 and July 3, 2010, respectively.

On May 9, 2011, we completed a public offering of $500 million aggregate principal amount of our 5.000% Senior Notes due 2021 (the “Notes”). The Notes are guaranteed by each of our wholly-owned domestic subsidiaries. These wholly-owned domestic subsidiaries may also be a guarantor under our primary bank credit facility. We used the net proceeds from the offering of the Notes to finance in part the CPT acquisition.

On April 28, 2011, we entered into a Fourth Amended and Restated Credit Agreement (the “Credit Facility”). The Credit Facility replaced our previous $800 million revolving credit facility. The Credit Facility creates an unsecured, committed credit facility of up to $700 million, with multi-currency sub facilities to support investments outside the U.S. The Credit Facility expires on April 28, 2016. Borrowings under the Credit Facility currently bear interest at the rate of London Interbank Offered Rate (“LIBOR”) plus 1.75%. Interest rates and fees on the Credit Facility will vary based on our credit ratings. We used borrowings under the Credit Facility to fund a portion of the CPT acquisition and to fund ongoing operations.

We are authorized to sell short-term commercial paper notes to the extent availability exists under the Credit Facility. We use the Credit Facility as back-up liquidity to support 100% of commercial paper outstanding. Our use of commercial paper as a funding vehicle depends upon the relative interest rates for our commercial paper compared to the cost of borrowing under our Credit Facility. As of July 2, 2011, we had no commercial paper outstanding.

Total availability under our existing Credit Facility was $437.9 million as of July 2, 2011, which was not limited by any of the credit agreement’s financial covenants as of that date.

Our debt agreements contain certain financial covenants, the most restrictive of which is a leverage ratio (total consolidated indebtedness, as defined, over consolidated net income before interest, taxes, depreciation, amortization and non-cash compensation expense (“EBITDA”), as defined) that may not exceed 4.0 to 1.0 as of July 2, 2011, 3.75 to 1.0 as of October 1, 2011, and 3.5 to 1.0 as of the last date of each of our fiscal quarters thereafter. We were in compliance with all financial covenants in our debt agreements as of July 2, 2011.

In addition to the Credit Facility, we have $40.0 million and $39.2 million (€27.0 million translated at the July 2, 2011 exchange rate) of other credit facilities, of which $21.8 (€15.0 million translated at the July 2, 2011 exchange rate) is committed until April 2016. Borrowings under these credit facilities bear interest at the rates of Euro Interbank Offered Rate (“Euribor”) plus 1.5% to 1.75%. We had $3.4 million and $18.0 million (€12.4 million translated at the July 2, 2011 exchange rate) of borrowings under these credit facilities as of July 2, 2011. Additionally, as part of the CPT acquisition we assumed certain capital leases with an outstanding balance of $18.3 million at July 2, 2011.

We have $105 million of outstanding private placement debt maturing in May 2012. We classified this debt as long-term as of July 2, 2011 as we have the intent and ability to refinance such obligation on a long-term basis under the Credit Facility.

Debt outstanding at July 2, 2011 matures on a calendar year basis as follows:

Derivatives and Financial Instruments

Fair value measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date:

Level 1:	Valuation is based on observable inputs such as quoted market prices (unadjusted) for identical assets or liabilities in active markets.
Level 2:	Valuation is based on inputs such as quoted market prices for similar assets or liabilities in active markets or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
Level 3:	Valuation is based upon other unobservable inputs that are significant to the fair value measurement.

In making fair value measurements, observable market data must be used when available. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement.

Cash-flow Hedges

In September 2005, we entered into a $100 million interest rate swap agreement with several major financial institutions to exchange variable rate interest payment obligations for fixed rate obligations without the exchange of the underlying principal amounts in order to manage interest rate exposures. The effective date of the fixed rate swap was April 25, 2006. The swap agreement has a fixed interest rate of 4.68% and expires in July 2013. The fixed interest rate of 4.68% plus the .60% interest rate spread over LIBOR results in an effective fixed interest rate of 5.28%. The fair value of the swap was a liability of $8.3 million, $9.4 million and $10.2 million at July 2, 2011, December 31, 2010 and July 3, 2010, respectively, and was recorded in Other non-current liabilities on the Condensed Consolidated Balance Sheets.

In August 2007, we entered into a $105 million interest rate swap agreement with a major financial institution to exchange variable rate interest payment obligations for a fixed rate obligation without the exchange of the underlying principal amounts in order to manage interest rate exposures. The effective date of the swap was August 30, 2007. The swap agreement has a fixed interest rate of 4.89% and expires in May 2012. The fixed interest rate of 4.89% plus the .50% interest rate spread over LIBOR results in an effective fixed interest rate of 5.39%. The fair value of the swap was a liability of $4.2 million, $6.4 million and $7.9 million at July 2, 2011, December 31, 2010 and July 3, 2010, respectively, and was recorded in Other non-current liabilities on the Condensed Consolidated Balance Sheets.

The variable to fixed interest rate swaps are designated as cash-flow hedges. The fair value of these swaps are recorded as assets or liabilities on the Condensed Consolidated Balance Sheets. Unrealized income/expense is included in Accumulated other comprehensive income (“OCI”) and realized income/expense and amounts due to/from swap counterparties, are recorded in Net interest expense in our Condensed Consolidated Statements of Income. We realized incremental expense resulting from the swaps of $4.7 million for each of the six months ended July 2, 2011 and July 3, 2010.

The variable to fixed interest rate swaps are designated as and are effective as cash-flow hedges. The fair value of these swaps are recorded as assets or liabilities on the Condensed Consolidated Balance Sheets, with changes in their fair value included in OCI.

Derivative gains and losses included in OCI are reclassified into earnings at the time the related interest expense is recognized or the settlement of the related commitment occurs.

Failure of one or more of our swap counterparties would result in the loss of any benefit to us of the swap agreement. In this case, we would continue to be obligated to pay the variable interest payments per the underlying debt agreements which are at variable interest rates of 3 month LIBOR plus .50% for $105 million of debt and 3 month LIBOR plus ..60% for $100 million of debt. Additionally, failure of one or all of our swap counterparties would not eliminate our obligation to continue to make payments under our existing swap agreements if we continue to be in a net pay position.

Our interest rate swaps are carried at fair value measured on a recurring basis. Fair values are determined through the use of models that consider various assumptions, including time value, yield curves, as well as other relevant economic measures, which are inputs that are classified as Level 2 in the valuation hierarchy defined by the accounting guidance.

In April 2011 as part of our planned debt issuance to fund the CPT acquisition, we entered into interest rate swap contracts to hedge movement in interest rates through the expected date of closing for a portion of the expected fixed rate debt offering. The swaps had a notional amount of $400 million with an average interest rate of 3.65%. In May 2011, upon the sale of the Notes, the swaps were terminated at a cost of $11.0 million. Because we used the contracts to hedge future interest payments, this amount is recorded in Prepaid expenses and other current assets within the Condensed Consolidated Balance Sheets and will be amortized as interest exposure over the 10 year life of the Notes.

We manage our economic and transaction exposure to certain market-based risks through the use of foreign currency derivative instruments. Our objective in holding derivatives is to reduce the volatility of net earnings and cash flows associated with changes in foreign currency exchange rates.

Foreign currency contract

In March 2011, we entered into a foreign currency option contract to reduce our exposure to fluctuations in the euro related to the planned CPT acquisition. The contract had a notional amount of €286.0 million, a strike price of 1.4375 and a maturity date of May 13, 2011. The fair value of the contract was an asset of $2.8 million at April 2, 2011 and was recorded in Prepaid expenses and other current assets on the Condensed Consolidated Balance Sheets. In May 2011, we sold the foreign currency option contract for $1.0 million. The net cost of $2.1 million is recorded in Selling, general and administrative on the Condensed Consolidated Statements on Income.

Income Taxes

11. Income Taxes

The provision for income taxes consists of provisions for federal, state and foreign income taxes. We operate in an international environment with operations in various locations outside the U.S. Accordingly, the consolidated income tax rate is a composite rate reflecting the earnings in the various locations and the applicable rates.

The effective income tax rate for the six months ended July 2, 2011 was 30.4% compared to 33.6% for the six months ended July 3, 2010. We continue to actively pursue initiatives to reduce our effective tax rate. The tax rate in any quarter can be affected positively or negatively by adjustments that are required to be reported in the specific quarter of resolution.

The total gross liability for uncertain tax positions was $24.8 million, $24.3 million and $27.9 million at July 2, 2011, December 31, 2010 and July 3, 2010, respectively. We record penalties and interest related to unrecognized tax benefits in Provision for income taxes and Net interest expense, respectively, on the Condensed Consolidated Statements of Income, which is consistent with our past practices.

Basis of Presentation and Responsibility for Interim Financial Statements

6 Months Ended

Jul. 02, 2011

Basis of Presentation and Responsibility for Interim Financial Statements

1. Basis of Presentation and Responsibility for Interim Financial Statements

We prepared the unaudited condensed consolidated financial statements following the requirements of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the United States can be condensed or omitted.

We are responsible for the unaudited financial statements included in this document. The financial statements include all normal recurring adjustments that are considered necessary for the fair presentation of our financial position and operating results. As these are condensed financial statements, one should also read our consolidated financial statements and notes thereto for the year ended December 31, 2010, which are included in our Current Report on Form 8-K dated May 2, 2011.

Revenues, expenses, cash flows, assets and liabilities can and do vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be indicative of those for a full year.

Our fiscal year ends on December 31. We report our interim quarterly periods on a 13-week basis ending on a Saturday.

In connection with preparing the unaudited condensed consolidated financial statements for the six months ended July 2, 2011, we have evaluated subsequent events for potential recognition and disclosure through the date of this filing.

New Accounting Standards

New Accounting Standards

2. New Accounting Standards

In June 2011, the Financial Accounting Standards Board (FASB) amended its guidance on the presentation of comprehensive income in financial statements to improve the comparability, consistency and transparency of financial reporting and to increase the prominence of items that are recorded in other comprehensive income. The new accounting guidance requires entities to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. The provisions of this new guidance are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011.

There were no other new accounting pronouncements issued or effective during the first six months of 2011 that have had or are expected to have a material impact on the Condensed Consolidated Financial Statements.
