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, which are included in our 2005 Annual Report on Form 10-K for the year ended December 31, 2005.
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.
Certain reclassifications have been made to prior years’ consolidated financial statements to conform to the current year’s presentation.
2.     New Accounting Standards
In December 2004, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 153, Exchanges of Nonmonetary Assets—An Amendment of APB Opinion No. 29, Accounting for Nonmonetary Transactions(“SFAS 153”). SFAS 153 eliminates the exception from fair value measurement for nonmonetary exchanges of similar productive assets in paragraph 21(b) of APB Opinion No. 29, Accounting for Nonmonetary Transactions, and replaces it with an exception for exchanges that do not have commercial substance. SFAS 153 specifies that a nonmonetary exchange has commercial substance if the future cash flows of the entity are expected to change significantly as a result of the exchange. SFAS 153 is effective for the fiscal periods beginning after June 15, 2005 and we adopted it on January 1, 2006. The adoption of SFAS 153 did not have a material impact on our consolidated results of operations, financial condition, or cash flow.
In November 2004, the FASB issued SFAS No. 151, Inventory Costs—An Amendment of ARB No. 43, Chapter 4 (“SFAS 151”). SFAS 151 amends the guidance in ARB No. 43, Chapter 4, “Inventory Pricing,” to clarify the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage). Among other provisions, the new rule requires that items such as idle facility expense, excessive spoilage, double freight, and rehandling costs be recognized as current-period charges regardless of whether they meet the criterion of “so abnormal” as stated in ARB No. 43. Additionally, SFAS 151 requires that the allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. SFAS 151 is effective for fiscal years beginning after June 15, 2005 and we adopted it on January 1, 2006. The adoption of SFAS 151 did not have on material impact on our consolidated results of operations or financial condition.
In March 2004, the Emerging Issues Task Force (“EITF”) reached a consensus on Issue No. 03-1, The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments. EITF 03-1 provides guidance on other-than-temporary impairment models for marketable debt and equity securities accounted for under SFAS 115 and non-marketable equity securities accounted for under the cost method. The EITF developed a basic three-step model to evaluate whether an investment is other-than-temporarily impaired. In November 2005, the FASB approved the issuance of FASB Staff Position FAS No. 115-1 and FAS No. 124-1, The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments. The FASB Staff Position (“FSP”) addresses when an investment is considered impaired, whether the impairment is other-than-temporary and the measurement of an impairment loss. The FSP also includes accounting considerations subsequent to the recognition of an other-than-temporary impairment and requires certain disclosures about unrealized losses that have not been recognized as other-than-temporary. The FSP is effective for reporting periods beginning after December 15, 2005 and we adopted it on January 1, 2006. The adoption of EITF No. 03-1 did not have a material impact on our consolidated results of operations or financial condition.
In May 2005, the FASB issued SFAS No. 154, Accounting Changes and Error Corrections (“SFAS 154”) which replaces Accounting Principles Board Opinion No. 20, Accounting Changes and SFAS No. 3,Reporting Accounting Changes in Interim Financial Statements—An Amendment of APB Opinion No. 28. SFAS 154 provides guidance on the accounting for and reporting of accounting changes and error corrections. It establishes retrospective application, or the latest practicable date, as the required method for reporting a change in accounting principle and the reporting of a correction of an error. SFAS 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. The adoption of SFAS 154 on January 1, 2006 has not had a material impact on our consolidated results of operations or financial condition.
In June 2005, the EITF reached a consensus on Issue No. 05-5, Accounting for Early Retirement or Postemployment Programs with Specific Features (such as Terms Specified in Altersteilzeit Early Retirement Arrangements). EITF No. 05-5 addresses the accounting for the bonus feature in the German Altersteilzeit (“ATZ”) early retirement programs and requires recognition of the program expenses at the time the ATZ contracts are signed. The EITF offers two transition alternatives, either cumulative effect or retrospective application. The EITF is effective for fiscal years beginning after December 15, 2005 and we adopted it on January 1, 2006. The adoption of EITF No. 05-5 did not have a material impact on our consolidated results of operations or financial condition.

3.     Stock-based Compensation
In the fourth quarter 2005, we adopted SFAS No. 123 (Revised 2004), Share-Based Payment (“SFAS 123R”), using the modified retrospective transition method as permitted by SFAS 123R. Under this transition method, we restated our 2005 interim financial statements. Total stock-based compensation expense for the first quarter of 2006 and 2005 was $6.6 million and $6.2 million, respectively.
Non-vested shares of our common stock were granted during the first quarter of 2006 to eligible employees with a vesting period of two to five years after issuance. The non-vested shares were granted at the market price on the date of grant and are expensed over the vesting period. Total compensation expense for non-vested share awards during the first quarter of 2006 and 2005 was $2.3 million and $1.9 million, respectively.
During the first quarter of 2006, option awards were granted under the Omnibus Stock Incentive Plan and the Outside Directors Nonqualified Stock Option plan with an exercise price equal to the market price of our common stock on the date of grant. Option awards granted in the first quarter of 2006 under the Omnibus Stock Incentive Plan did not have a reload feature attached to the option. The options vest one-third each year over a three-year period and have a ten-year contractual term. Compensation expense equal to the grant date fair value is recognized for these awards over the vesting period. Certain option grants were reloaded during the quarter for individuals retiring shares to pay the exercise price of options granted prior to 2006. Reload options are vested and expensed immediately. Total compensation expense for stock option awards was $4.3 million for the first quarter of both 2006 and 2005.
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:
         
  April 1  April 2 
  2006  2005 
 
Expected stock price volatility
  31.5%  34.5%
Expected life
 4.5 yrs. 3.6 yrs.
Risk-free interest rate
  4.56%  4.00%
Dividend yield
  1.44%  1.30%
The weighted-average fair value of options granted during the first quarter of 2006 and 2005 was $11.49 and 10.93 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 SFAS No. 123R, 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. The increase in the expected life in 2006 compared to 2005 was the result of a decrease in exercise activity and the stock price in the preceding year. 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.

5.     Acquisitions
On December 1, 2005, we acquired McLean Thermal Management, Aspen Motion Technologies, and Electronic Solutions businesses from APW, Ltd. (collectively, “Thermal”) for $140.0 million, including a cash payment of $138.9 million and transaction costs of $1.1 million. During 2006, we paid an additional $2.2 million in transaction costs. These businesses provide thermal management solutions and integration services to the telecommunications, data communications, medical, industrial, and security markets as part of our Technical Products Group. Goodwill recorded as part of the initial purchase price allocation was $93.7 million, all of which is tax deductible. We continue to evaluate the purchase price allocation for the Thermal acquisition, including intangible assets, contingent liabilities, plant rationalization costs, and property, plant and equipment. We expect to revise the purchase price allocation as better information becomes available in 2006.
On February 23, 2005, we acquired certain assets of Delta Environmental Products, Inc. and affiliates (collectively, “DEP”), a privately-held company, for $10.3 million, including a cash payment of $10.0 million, transaction costs of $0.2 million, and debt assumed of $0.1 million. The DEP product line addresses the water and wastewater markets and is part of our Water Group. Goodwill recorded as part of the initial purchase price allocation was $9.3 million, all of which is tax deductible. We finalized the purchase price allocation for the DEP acquisition during the first quarter of 2006.
The following pro forma condensed consolidated financial results of operations are presented as if the acquisitions described above had been completed at the beginning of each period presented.

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 synergies that would have been expected to result from the integration of these acquisitions. 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.
6.     Discontinued Operations
Effective after the close of business on October 2, 2004, we completed the sale of our former Tools Group to The Black & Decker Corporation (“BDK”). Pursuant to the purchase agreement for the sale of our former Tools Group, we completed the repurchase of a manufacturing facility in Suzhou, China from BDK for approximately $5.7 million in January 2006. We recorded no gain or loss on the repurchase. On March 8, 2006, we received notice regarding the settlement of an outstanding net asset value dispute with BDK relating to the purchase price for the sale of our former Tools Group. The decision by the arbitrator constituted a final resolution of all disputes between BDK and us regarding the net asset value. We paid the final purchase price adjustment of $16.1 million plus interest of $1.1 million in March 2006, resulting in an incremental pre-tax loss on disposal of discontinued operations of $3.4 million or $1.6 million net of tax.
In 2001, we completed the sale of our former Service Equipment businesses (Century Mfg. Co./Lincoln Automotive Company) to Clore Automotive, LLC. In the fourth quarter of 2003, we reported an additional loss from discontinued operations of $2.9 million related to exiting the remaining two facilities. In March 2006, we exited a leased facility from our former Service Equipment business resulting in a net cash outflow of $2.2 million and an immaterial gain from disposition.
Operating results of the discontinued operations for the first quarter of 2006 and 2005 are summarized below:

We have a multi-currency revolving Credit Facility (the “Credit Facility”) of $800 million expiring on March 4, 2010. The interest rate on the loans under the $800 million Credit Facility is LIBOR plus 0.625%. Interest rates and fees on the Credit Facility vary based on our credit ratings.
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. As of April 1, 2006, we had $166.3 million of commercial paper outstanding that matures within 51 days. All of the commercial paper was classified as long-term as we have the intent and the ability to refinance such obligations on a long-term basis under the Credit Facility.
We were in compliance with all debt covenants as of April 1, 2006.
In addition to the Credit Facility, we have $25 million of uncommitted credit facilities, under which we had no borrowings as of April 1, 2006.
Long-term debt outstanding at April 1, 2006 matures on a calendar year basis as follows:

11.     Derivatives and Financial Instruments
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 principle amounts in order to manage interest rate exposures. The effective date of the fixed rate swap is 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 at April 1, 2006 was $3.4 million and was recorded in other assets at April 1, 2006.
The variable to fixed interest rate swap is designated as and is effective as a cash-flow hedge. The fair value of the swap is recorded on the balance sheet, with changes in fair values included in Other Comprehensive Income (“OCI”). Derivative gains and losses included in OCI are recorded in earnings at the time the related interest rate expense is recognized or the settlement of the related commitment occurs.
12.     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 three months ended April 1, 2006 was 34.0% compared to 33.9% for the three months ended April 2, 2005. The tax rate for the first quarter of 2006 includes a $0.9 million favorable adjustment related to a prior year tax return. The 2005 effective tax rate included a favorable settlement for an IRS exam for the periods of 1998-2001, resulting in the release of tax contingency reserves of $1.3 million. We expect the effective tax rate for the remainder of 2006 to be approximately 35.5%, resulting in a full year effective income tax rate of 35.2 %. However, 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.

16.     Commitments and Contingencies
Environmental and Litigation
There have been no further material developments from the disclosures contained in our 2005 Annual Report on Form 10-K, other than those matters identified below.
Horizon Litigation
Twenty-eight separate lawsuits involving 29 primary plaintiffs, a class action, and claims for indemnity by Celebrity Cruise Lines, Inc. (Celebrity) were brought against Essef Corporation (Essef) and certain of its subsidiaries prior to our acquisition of Essef in August 1999. Celebrity has alleged that it had sustained economic damages due to loss of use of the M/V Horizon while it was dry-docked.
The claims against Essef and its involved subsidiaries were based upon the allegation that Essef designed, manufactured, and marketed two sand swimming pool filters that were installed as a part of the spa system on the Horizon, and allegations that the spa and filters contained Legionnaire’s disease bacteria that infected certain passengers on cruises from December 1993 through July 1994.
The individual and class claims by passengers were tried and resulted in an adverse jury verdict finding liability on the part of the Essef defendants (70%) and Celebrity and its sister company, Fantasia (together 30%).
After expiration of post-trial appeals, we paid all outstanding punitive damage awards of $7.0 million in the Horizon cases, plus interest of approximately $1.6 million, in January 2004. We had reserved for the amount of punitive damages awarded at the time of the Essef acquisition. A reserve for the $1.6 million interest cost was recorded in 2003. All of the personal injury cases have now been resolved through either settlement or trial.
The only remaining unresolved claims in this case are those brought by Celebrity for damages resulting from the outbreak. Celebrity filed an amended complaint seeking attorney fees and costs for prior litigation as well as out-of-pocket losses, lost profits, and loss of business enterprise value. Discovery commenced late in 2004, and was completed in August 2005. Celebrity’s claims for damages exceed $185 million. Assuming matters of causation, standing, contribution and proof are decided against it, Essef’s experts believe that damages should amount to no more than approximately $16 to $25 million. Dispositive motions in this matter were filed in August 2005, which were decided in December 2005. Celebrity’s motion for indemnity from Essef for payments made by Celebrity for passenger claims of approximately $2.3 million was denied. Essef’s motion for dismissal of certain damage claims was denied without prejudice to renewal in conjunction with both parties’ motions to exclude certain expert testimony. Those hearings were held in April 2006 and Essef expects to review its motion to dismiss certain claims. Trial is currently scheduled for June 2006. We believe our reserves for any liability to Celebrity are adequate and intend to vigorously defend against these claims.
Other
We are occasionally a party to other litigation arising in the normal course of business. We regularly analyze current information and, as necessary, provide accruals for probable liabilities based on the expected eventual disposition of these matters. While it is possible that the Company’s cash flows and results of operations in a particular quarter or year could be materially affected by the one-time impacts of the resolution of such contingencies, it is the opinion of management that the ultimate disposition of these matters will not have a material impact on the Company’s financial position, or ongoing results of operations and cash flows.

ITEM 2.      MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
FORWARD-LOOKING STATEMENTS
This report contains statements that we believe to be “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements give our current expectations or forecasts of future events. Forward-looking statements generally can be identified by the use of forward-looking terminology such as “may,” “will,” “expect,” “intend,” “estimate,” “anticipate,” “believe,” “project,” or “continue,” or the negative thereof or similar words. From time to time, we also may provide oral or written forward-looking statements in other materials we release to the public. Any or all of our forward-looking statements in this report and in any public statements we make could be materially different from actual results. They can be affected by assumptions we might make or by known or unknown risks or uncertainties. Consequently, we cannot guarantee any forward-looking statements. Investors are cautioned not to place undue reliance on any forward-looking statements. Investors should also understand that it is not possible to predict or identify all such factors and should not consider the following list to be a complete statement of all potential risks and uncertainties.
The following factors may impact the achievement of forward-looking statements:
 changes in general economic and industry conditions, such as:
  the strength of product demand;
 
  the intensity of competition, including that from foreign competitors;
 
  pricing pressures;
 
  market acceptance of new product introductions and enhancements;
 
  the introduction of new products and enhancements by competitors;
 
  our ability to maintain and expand relationships with large customers;
 
  our ability to source raw material commodities from our suppliers without interruption and at reasonable prices;
 
  our ability to source components from third parties, in particular from foreign manufacturers, without interruption and at reasonable prices; and
 
  the financial condition of our customers;
 our ability to identify, complete, and integrate acquisitions successfully and to realize expected synergies on our anticipated timetable;
 
 changes in our business strategies, including acquisition, divestiture, and restructuring activities;
 
 domestic and foreign governmental and regulatory policies;
 
 general economic and political conditions, such as political instability, the rate of economic growth in our principal geographic or product markets, or fluctuations in exchange rates;
 
 changes in operating factors, such as continued improvement in manufacturing activities and the achievement of related efficiencies, cost reductions, and inventory risks due to shifts in market demand and costs associated with moving production overseas;
 
 unanticipated developments that could occur with respect to contingencies such as litigation, intellectual property matters, product liability exposures and environmental matters;
 
 our ability to continue to successfully generate savings from our excellence in operations initiatives consisting of lean enterprise, supply management and cash flow practices;
 
 our ability to accurately evaluate the effects of contingent liabilities such as taxes, product liability, environmental, and other claims; and
 
 our ability to access capital markets and obtain anticipated financing under favorable terms.
The foregoing factors are not exhaustive, and new factors may emerge or changes to the foregoing factors may occur that would impact our business. We assume no obligation, and disclaim any duty, to update the forward-looking statements in this report.
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, treatment, storage, and enjoyment of water. Our Technical Products Group is a global leader in the global enclosures market that designs, manufactures, and markets standard, modified, and custom enclosures that house and protect sensitive controls, components; thermal management products; and accessories. In 2006, we expect our Water Group and Technical Products Group to generate approximately 70 percent and 30 percent of total revenues, respectively.
Our Water Group has progressively become a more important part of our business portfolio with sales increasing from $100 million in 1995 to approximately $2.1 billion in 2005. We believe the water industry is structurally attractive as a result of a growing demand for clean water and the large global market size (of which we have identified a target industry segment totaling $50 billion). Our vision is to become a leading global provider of innovative products and systems used in the movement, treatment, storage, and enjoyment of water.
Our Technical Products Group operates in a large global market with significant potential for growth in industry segments such as defense, security, medical, and networking. We believe we have the largest enclosures industrial and commercial distribution network in North America and the highest enclosures brand recognition in the industry. From mid-2001 through 2003, the Technical Products Group experienced significantly lower sales volumes as a result of severely reduced capital spending in the industrial and commercial markets and over-capacity and weak demand in the datacom and telecom markets. In 2004, 2005, and the first quarter of 2006, sales volumes increased due to the addition of new distributors, new products, and higher demand in all targeted markets. In addition, through the success of our Pentair Integrated Management Systems (“PIMS”) initiatives, we have increased Technical Products segment margins for 17 consecutive quarters.

Key Trends and Uncertainties
The following trends and uncertainties affected our financial performance in the first three months of 2006 and will likely impact our results in the future:
 We experience seasonal demand in a number of markets within our Water Group. End-user demand for pool/spa equipment follows warm weather trends and is at seasonal highs from March to July. The magnitude of the sales spike is partially mitigated by effective use of the distribution channel by employing some advance sales programs (generally including extended payment terms and/or additional discounts). Demand for residential and agricultural water systems is also affected by weather patterns particularly related to heavy flooding and droughts.
 
 We expect our operations to continue to benefit from our PIMS initiatives which include: strategy deployment; lean enterprise with special focus on sourcing and supply management, cash flow management, and lean operations; and IGNITE, our process to drive organic growth.
 
 We are experiencing material cost inflation in a number of our businesses. We are striving for greater productivity improvements and implementing selective increases in selling prices to help mitigate cost increases in base materials such as steel and resins, freight, fuel, health care, and insurance.
 
 Free cash flow, which we define as cash flow from operating activities less capital expenditures, including both continuing and discontinued operations, plus proceeds from sale of property and equipment, exceeded $200 million for the fourth consecutive year in 2005 and is expected to be approximately $200 million in 2006. See our discussion of Other financial measures under the caption “Liquidity and Capital Resources” of this report.
 
 In the first three months of 2006, the U.S. dollar was stronger against the Euro when compared to the same period in 2005. This resulted in year-over-year unfavorable foreign currency effects, which may or may not continue to trend unfavorably in the future.
 
 The effective tax rate for the first three months of 2006 was 34.0%. We estimate our effective income tax rate for the remainder of 2006 to be 35.5%, resulting in a full year effective income tax rate of 35.2%. 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.
Outlook
In 2006 and beyond, our operating objectives include the following:
 Continue to drive for operating excellence through PIMS: lean enterprise initiatives, supply management practices, and cash flow management;
 
 Continue the integration of acquisitions and realize identified synergistic opportunities;
 
 Continue proactive talent management process building competencies in international management and other key functional areas;
 
 Achieve organic sales growth (in excess of market growth), particularly in international markets; and
 
 Continue to make strategic acquisitions to grow and expand our existing platforms in our Water and Technical Products Groups.

Consolidated net sales
The 8.7 percent increase in consolidated net sales in the first quarter of 2006 from 2005 was primarily driven by:
 organic sales growth of approximately 5 percent (excluding the effects of acquisitions and foreign currency exchange), which includes selective increases in selling prices to mitigate inflationary cost increases; and
 
 an increase in sales volume due to our December 1, 2005 acquisition of the Thermal businesses.
These increases were partially offset by:
 unfavorable foreign currency effects as the stronger U.S. dollar decreased the U.S. dollar value of sales denominated in foreign currencies.
Net sales by segment and the change from the prior year period were as follows:

Water
The 1.0 percent increase in Water segment net sales in the first quarter of 2006 from 2005 was primarily driven by:
 organic sales growth of approximately 2 percent (excluding foreign currency exchange) which includes selective increases in selling prices to mitigate inflationary cost increases:
  an increase in sales of water systems, wastewater, and commercial pumps and Everpure foodservice filtration; and
 
  a strong international sales performance.
These increases were partially offset by:
 unfavorable foreign currency effects;
 
 lower sales of retail pumps and filtration; and
 
 timing of municipal pump shipments.

Technical Products
The 28.7 percent increase in Technical Product segment net sales in the first quarter 2006 from 2005 was primarily driven by:
 organic sales growth of approximately 13 percent (excluding acquisitions and foreign currency exchange) which includes selective increases in selling prices to mitigate inflationary cost increases:
  continued strong North American sales in petrochemical, commercial, construction, data, medical, and food and beverage markets;
 
  a strong performance in Europe due to sales of several new products and a large telecom project for outdoor cabinets;
 
  higher sales in Asia driven by continued penetration in China, and a general market recovery in Japan; and
 an increase in sales volume driven by our December 1, 2005 acquisition of the Thermal businesses.
These increases were partially offset by:
 unfavorable foreign currency effects.

Percentage point change

The unchanged gross profit as a percentage of sales in the first quarter of 2006 from 2005 was primarily the result of:
 selective increases in selling prices in our Water and Technical Products Groups to mitigate inflationary cost increases;
 
 savings generated from our PIMS initiatives including lean and supply management practices; and
 
 cost leverage from our increase in sales volume in the Technical Products Group.
These were offset by:

The 0.1 percentage point increase in the tax rate in the first quarter of 2006 from 2005 was primarily the result of:
  a favorable settlement in the first quarter of 2005 of an IRS exam for the periods 1998-2001 resulting in a release of tax contingency reserves in the amount of $1.3 million.
The increase was offset by:
  a favorable adjustment of $0.9 million in the first quarter of 2006 related to a prior year tax return.
We estimate our effective income tax rate for the remaining quarters of this year will be 35.5% resulting in a full year effective income tax rate of 35.2%.
LIQUIDITY AND CAPITAL RESOURCES
Cash requirements for working capital, capital expenditures, equity investments, acquisitions, debt repayments, share repurchases, and dividend payments are generally funded from cash generated from operations, availability under existing committed revolving credit facilities, and in certain instances, public and private debt and equity offerings.
We experience seasonal cash flows primarily due to seasonal demand in a number of markets within our Water Group. End-user demand for pool/spa equipment follows warm weather trends and is at seasonal highs from March to July. We somewhat mitigate the magnitude of the sales spike through effective use of the distribution channel by employing some advance sales programs (generally including extended payment terms and/or additional discounts). Demand for residential and agricultural water systems is also affected by weather patterns particularly related to heavy flooding and droughts.
The following table presents selected working capital measurements calculated from our monthly operating results based on a 13-month moving average:

Days of sales in accounts receivable

Days inventory on hand
 71  70  65 
Days in accounts payable
 56  56  57 
Operating activities
Cash used for operating activities was $92.3 million in the first three months of 2006 compared with cash used for operating activities of $80.1 million in the prior year comparable period. The increase in cash used for operating activities was due to working capital increases related to seasonal increases in accounts receivable, specifically Pentair’s Pool business, and increased inventory levels to hedge against competitive actions. The increase in days of sales in accounts receivable as of April 1, 2006 compared to December 31, 2005 was primarily related to the seasonality of our Water Group’s sales, specifically Pentair Pool’s early-buy program that occurred in the fourth quarter of 2005 to include extended payment terms. The increase in days inventory on hand as of April 1, 2006 compared to December 31, 2005 was attributable to the seasonal building of inventory levels, increased sourcing from Asia, and changes in purchasing terms to hedge against competitive actions. In the future, we expect our working capital ratios to improve as we are able to complete our facility rationalization activities and capitalize on our PIMS initiatives.
Investing activities
Capital expenditures in the first three months of 2006 were $9.1 million compared with $21.3 million in the prior year period. We currently anticipate capital expenditures for fiscal 2006 will be approximately $80 to $85 million, primarily for expansion of low cost country manufacturing facilities, implementation of a unified business systems infrastructure in Europe, selective increases in equipment capacity, new product development, and general maintenance capital.
Divestiture activities during 2006 relate to the following: In January 2006, pursuant to the purchase agreement for the sale of our former Tools Group, we completed the repurchase of a manufacturing facility in Suzhou, China from BDK for approximately $5.7 million. On March 8, 2006, we received notice regarding the settlement of an outstanding dispute with BDK regarding the net asset value relating to the purchase price for the sale of our former Tools Group. The decision by the arbitrator constituted a final resolution of all disputes between BDK and us regarding the net asset value. We paid the final purchase price adjustment of $16.1 million in March 2006. Also in March 2006, we exited a leased facility formerly used by our discontinued Service Equipment business. The net cash outflow from this transaction was $2.2 million.
On February 23, 2005, we acquired the assets of Delta Environmental Products, Inc. and affiliates (collectively, “DEP”), a privately held company, for $10.3 million, including a cash payment of $10.0 million, transaction costs of $0.2 million, plus debt assumed of $0.1 million. The DEP product line addresses the water and wastewater markets and is part of our Water Group.
Financing activities
Net cash provided by financing activities was $130.7 million in the first three months of 2006 compared with $125.4 million provided by financing activities in the prior year period. 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 from stock option exercises, and tax benefits related to stock-based compensation.
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. As of April 1, 2006, we had $166.3 million of commercial paper outstanding that matures within 51 days. All of the commercial paper was classified as long-term as we have the intent and the ability to refinance such obligations on a long-term basis under the Credit Facility.
We were in compliance with all debt covenants as of April 1, 2006.
In addition to the Credit Facility, we have $25 million of uncommitted credit facilities, under which we had no borrowings as of April 1, 2006.
Our current credit ratings are as follows:
     
Rating Agency  Long-Term Debt Rating Current Rating Outlook
Standard & Poor’s
 BBB Stable
Moody’s
 Baa3 Stable
As of April 1, 2006, our capital structure consisted of $892.3 million in total indebtedness and $1,594.7 million in shareholders’ equity. The ratio of debt-to-total capital at April 1, 2006 was 35.9 percent, compared with 32.6 percent at December 31, 2005 and 37.0 percent at April 2, 2005. Our targeted debt-to-total capital ratio is approximately 40 percent. We will exceed this target ratio from time to time as needed for operational purposes and/or acquisitions.

Table of Contents

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. In order to meet these cash requirements, we intend to use available cash and internally generated funds, and to borrow under our committed and uncommitted credit facilities.
Dividends paid in the first three months of 2006 were $14.2 million, or $0.14 per common share, compared with $13.4 million, or $0.13 per common share, in the prior year period. We have increased dividends every year for the last 30 years and expect to continue paying dividends on a quarterly basis.
There have been no material changes with respect to the contractual obligations or off-balance sheet arrangements described in our Annual Report on Form 10-K for the year ended December 31, 2005.
Other financial measures
In addition to measuring our cash flow generation or usage based upon operating, investing, and financing activities included in the consolidated statements of cash flows, we also measure our free cash flow and our conversion of net income. Free cash flow and conversion of net income are non-GAAP financial measures that we use to assess our cash flow performance, and we have a long-term goal to consistently generate free cash flow that equals or exceeds 100 percent of our net income. We believe free cash flow and conversion of net income are important measures of operating performance, because they provide our investors and us with a measurement of cash generated from operations that is available to pay dividends and repay debt. In addition, free cash flow and conversion of net income are used as a criterion to measure and pay compensation-based incentives. Our measure of free cash flow and conversion of net income may not be comparable to similarly titled measures reported by other companies. The following table is a reconciliation of free cash flow and a calculation of the conversion of net income with cash flows from continuing and discontinued operating activities:

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
Board of Directors and Shareholders of
     Pentair, Inc.
We have reviewed the accompanying condensed consolidated balance sheets of Pentair, Inc. and Subsidiaries (the “Company”) as of April 1, 2006 and April 2, 2005, the related condensed consolidated statements of income and cash flows for the three month periods ended April 1, 2006 and April 2, 2005. These interim financial statements are the responsibility of the Company’s management.
We conducted our reviews in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.
Based on our reviews, we are not aware of any material modifications that should be made to such condensed consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.
We have previously audited, in accordance with standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of the Company as of December 31, 2005, and the related consolidated statements of income, changes in shareholders’ equity, and cash flows for the year then ended (not presented herein); and in our report dated February 27, 2006, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2005 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

PART II OTHER INFORMATION
ITEM 1.      Legal Proceedings
Environmental and Litigation
There have been no further material developments from the disclosures contained in our 2005 Annual Report on Form 10-K, other than those matters identified below.
Horizon litigation
Twenty-eight separate lawsuits involving 29 primary plaintiffs, a class action, and claims for indemnity by Celebrity Cruise Lines, Inc. (Celebrity) were brought against Essef Corporation (Essef) and certain of its subsidiaries prior to our acquisition of Essef in August 1999. Celebrity has alleged that it had sustained economic damages due to loss of use of the M/V Horizon while it was dry-docked.
The claims against Essef and its involved subsidiaries were based upon the allegation that Essef designed, manufactured, and marketed two sand swimming pool filters that were installed as a part of the spa system on the Horizon, and allegations that the spa and filters contained Legionnaire’s disease bacteria that infected certain passengers on cruises from December 1993 through July 1994.
The individual and class claims by passengers were tried and resulted in an adverse jury verdict finding liability on the part of the Essef defendants (70%) and Celebrity and its sister company, Fantasia (together 30%).
After expiration of post-trial appeals, we paid all outstanding punitive damage awards of $7.0 million in the Horizon cases, plus interest of approximately $1.6 million, in January 2004. We had reserved for the amount of punitive damages awarded at the time of the Essef acquisition. A reserve for the $1.6 million interest cost was recorded in 2003. All of the personal injury cases have now been resolved through either settlement or trial.
The only remaining unresolved claims in this case are those brought by Celebrity for damages resulting from the outbreak. Celebrity filed an amended complaint seeking attorney fees and costs for prior litigation as well as out-of-pocket losses, lost profits, and loss of business enterprise value. Discovery commenced late in 2004, and was completed in August 2005. Celebrity’s claims for damages exceed $185 million. Assuming matters of causation, standing, contribution and proof are decided against it, Essef’s experts believe that damages should amount to no more than approximately $16 to $25 million. Dispositive motions in this matter were filed in August 2005, which were decided in December 2005. Celebrity’s motion for indemnity from Essef for payments made by Celebrity for passenger claims of approximately $2.3 million was denied. Essef’s motion for dismissal of certain damage claims was denied without prejudice to renewal in conjunction with both parties’ motions to exclude certain expert testimony. Those hearings were held in April 2006 and Essef expect to review its motion to dimiss certain claims. Trial is currently scheduled for June 2006. We believe our reserves for any liability to Celebrity are adequate and intend to vigorously defend against these claims.
Other
We are occasionally a party to other litigation arising in the normal course of business. We regularly analyze current information and, as necessary, provide accruals for probable liabilities based on the expected eventual disposition of these matters. While it is possible that the Company’s cash flows and results of operations in a particular quarter or year could be materially affected by the one-time impacts of the resolution of such contingencies, it is the opinion of management that the ultimate disposition of these matters will not have a material impact on the Company’s financial position, or ongoing results of operations and cash flows.
ITEM 1A. There have been no material changes from the risk factors previously disclosed in Item 1A. of our 2005 Annual Report on Form 10-K.
