PART I

ITEM 1. BUSINESS

(a) General Development of the Business.

Pentair, Inc. (the "Company"“Company” or "Pentair"“Pentair”) was incorporated in 1966 under the laws of Minnesota. In the past year, the Company has not changed its form of organization or mode of conducting business. The Company grows through internal development and acquisitions. As in the past, periodic dispositions of assets or business units are possible when they no longer fit with the long-term strategies of the Company.

Effective January 1, 1994, the Company acquired the net assets and the subsidiaries of Schroff GmbH (Schroff) from Fried. Krupp AG Hoesch-Krupp. Schroff manufactures and sells enclosures, cases, subracks and accessories for commercial electronic and instrumentation applications.

In September 1994, Pentair announced that it was exploring strategic alternatives for its paper businesses, including their possible sale. In the second quarter of 1995, all of the Pentair paper businesses were sold. On April 1, 1995 the Company sold its Cross Pointe Paper Corporation subsidiary to Noranda Forest, Inc. On June 30, 1995 the Company sold Niagara of Wisconsin Paper Corporation, its 50% share of Lake Superior Paper Industries (LSPI) joint venture and its 12% share of Superior Recycled Fiber Industries (SRFI) to Consolidated Papers, Inc.

The sale of its paper businesses has permitted Pentair to focus its commitments and resources on its industrial products businesses, building upon the strong growth and leading market positions these businesses have achieved.

Effective November 1, 1995, the Company acquired Fleck Controls, Inc., a manufacturer of control valves, which are major components in residential water softeners, and commercial and industrial water conditioning systems. Fleck Controls was Pentair'sPentair’s first entry into the water treatment industry.

During 1996, the Company completed four strategic acquisitions that strengthened market positions throughout the world. In January, Myers acquired Aplex to broaden its industrial pump line. In June, Porter-Cable acquired FLEX, a German power tool company. In November, the Company acquired Century Manufacturing, a manufacturer that serves service equipment markets, complementing its Lincoln Automotive subsidiary. In December, Fleck Controls purchased SIATA, an Italian manufacturer of water conditioning control equipment.

During 1997, the Company completed 3 strategicthree acquisitions. In January, Schroff France acquired Transrack S.A., a maker of complementary cases and enclosures. In July, Century Manufacturing acquired P && F Technologies, , a maker of refrigerant recycling equipment. In August, Pentair acquired the General Signal Pump Group in a significant acquisition designed to create a critical mass in the water and wastewater pump markets.

Also in 1997, in another strategic development, the Company divested its Federal Cartridge sporting ammunition business.

In the fourth quarter of 1997, the Company realigned its subsidiaries into 3three operating groups to reflect its growing focus in its addressed markets: Professional Tools and Equipment, Water and Fluid Technologies and Electrical and Electronic Enclosures. Delta International, Porter-Cable, Lincoln Automotive and Century Manufacturing make up the Professional Tools and Equipment segment, which markets its products to professional users and sophisticated individual users through similar channels. The Water and Fluid Technologies segment consists of the Pentair Pump Group, Fleck Controls, and Lincoln Industrial, all of which share aspects of manufacturing process, applied technology, and distribution channels. Pentair's Hoffman and Schroff enclosures businesses comprise the Electrical and Electronic Enclosures segment.

During 1998, the Company completed 3 strategicthree acquisitions. In January, Pentair acquired ORSCO, Inc., a maker of oil lubrication systems. In April, Century Manufacturing acquired the assets of T-Tech Industries, a maker of automatic transmission fluid exchangers and accessories. In October, Pentair acquired The Walker Dickson Group Limited (now Pentair Enclosures U.K. and its subsidiaries)subsidiaries; its US affiliates are now part of Pentair Electronic Packaging), a maker of custom and standard enclosures, subracks and systems.

During 1999, Pentair made three acquisitions. In April, Pentair acquired WEB Tool and Manufacturing (WEB), a designer,

In evaluating financial performance, management focuses on operating income as a segment'ssegment’s measure of profit or loss. Operating income is before interest expense, interest income and income taxes. Management uses a variety of balance sheet ratios to measure the business. The primary focus is on maximizing the return from each segment'ssegment’s assets, excluding cash and temporary investments. The accounting policies of the segments are the same as those described in the summary of significant accounting policies (Note 1 of Notes to the Consolidated Financial Statements). Most intersegment sales are component parts and are sold at cost plus an equitable division of manufacturing and marketing profits. The remaining intercompany sales are finished product and are sold based on current market pricing to third parties.

Pro Air II.

Products are sold through various channels, including networks of independent industrial and warehouse distributors, home centers and national retailers, hardware stores, and through mail order and catalogues. Certain service equipment is sold under private label programs. The explosive growth in the home center channel in the last few years has resulted in a significant increase in PTE tool sales through this channel. Nationwide, home centers have become the primary channel for all sales of power and bench top tools to end users. While warehouse distributors continue to be the most significant channel for service equipment sales, product entry into retail and home center stores has continued to grow. Tool markets include

Markets include: do-it-yourself(DIY)/homeshop; residential, commercial, and industrial construction; remodeling and cabinet, case good and furniture makers. Service equipment markets includemakers; industrial fabrication and maintenance, automotive repair and vehicle maintenance, farm and industrial equipment; and aftermarket and retail channels for professional and do-it- yourselfDIY automotive and body repair.

Each of the businesses in the PTE segment faces a number of competitors, some of whom are larger and have more resources. Competition in the PTE segment has been intense and growing more so for the past few years, especially as these industries consolidate. The toolIn most markets, have become extremely competitive, asonly a few large players remain, each having extensive product lines. The Company'sCompany’s tool businesses are no longer perceived as niche players, but have become significant general competitors, even though their addressed market of professional users and higher-end DIY customers does not extend into the larger general consumer tool markets. Each of the businesses in the PTE segment faces a number of competitors, many of whom are larger, have more resources and are more fully integrated. Growth in these markets should come from product development, continued penetration of expanding market channels and acquisitions. Patents and proprietary technology are becoming more significant infor this market. segment.

Competition at the end-user level focuses primarily on brand names, product performance and features, quality, service and, most importantly, price. The competition for shelf space at home centers and national retailers is particularly intense, demanding continuing product innovation, special inventory and delivery programs, after-sale service capability and competitive pricing. The strategy of the businesses in the PTE segment is to be the price/quality leader in its selected markets. Their success in maintaining their respective positions in the marketplace is largely due to continuing product feature innovations, new products and outsourcing and other cost-reduction measures. As leaders in their markets, these businesses are able to command access for their products in the most important channels in the face of growing competition.

Description of the Water and Fluid Technologies Segment: Products; markets; competition

Products include: pumps for wells, sump pumps for residential service, submersible non-clog and grinder pumps and systems for residential, commercial, and municipal service, pumps for water treatment and wastewater solid handling, fire pumps, and reciprocating, turbine, submersible, and centrifugal pumps for commercial and industrial services; a complete line of control valves and composite and fiberglass storage tanks and filtration systems used in the manufacture of water softeners and filtration, deionization, and desalination systems; pool and spa equipment such as valves, pumps, filters, lights and related equipment; and automated and manual lubrication systems and equipment and pumps and pumping stations for fluid transfer applications.

The products are sold in the United States, Canada, and overseas under the brand names Myers, Aplex, Fairbanks Morse, Aurora, Water Ace, Shur Dri, Hydromatic, Fleck, Structural, Wellmate, Codeline, Pac-Fab, Purex-Triton, Rainbow Lifegard, American, Compool, Kreepy Krauly, FIBERworks, SIATA, Lincoln, Lincoln Industrial and ORSCO.

Products are sold through various channels, including the do-it- yourselfDIY market for retail sale through home centers and hardware stores, by specially qualifiedspecially-qualified systems distributors with design, installation and service capability, through industrial supply and specialty distributors and stores, directly by internal sales organizations, and through national catalog distribution. In the pool market, the Company sells its products primarily to distributors and directly to installers. Sales of spa and jetted tub fittings and pumps are made primarily to OEMs with the balance to distributors.

Markets include wholesale and retail distribution to residential users; commercial HVAC, plumbing, and fire pump markets; municipal waste and water treatment facilities and industrial companies; manufacturers and assemblers who supply residential and commercial markets with standard and custom designed water softener products; pool and spa markets; and heavy industry (steel mills, cement plants, pulp and paper, power plants), automobile manufacturers, commercial vehicles, agriculture, construction equipment, food and beverage, mining, printing and general lubrication markets.

The water and waste water pump industry has experiencedcontinues a significant trend toward consolidation, in 1997, evidenced in part by the acquisitions of Goulds Pump Inc. by ITT Corporation and of the former General Signal Pump Group by Pentair.Pentair, both in 1997. The latter acquisition by the Company significantly expanded the number, range and targeted markets of the Pentair Pump Group. The Company continues to rationalize the product lines, facilities and manufacturing operations of these businesses to cut costs and increase efficiencies. The water treatment industry is also experiencing rapid consolidation, as evidenced by United StatesUS Filter Corporation's 1997Corporation’s 1998 acquisition of Culligan Water Technologies, Inc., both current (both customers of the Company'sPentair Water Treatment) and US Filter’s subsequent acquisition by Vivendi in 1999.

In addition, there are a number of captive valve manufacturers whose production is used to support their own sales of water conditioning systems.systems in competition with customers of Pentair Water Treatment. Growth will come largely from nicheproduct development, coordinated marketing programs, increased channel penetration and acquisitions of additional technologies.

Each of the businesses in the WFT segment faces a number of competitors, some of which are larger, have more resources and product development.are more vertically integrated. Competition in the commercial and residential pump markets focuses on brand names, product performance, quality and price. While home center and national retailers are important for residential lines of water and wastewater pumps, they are much less important in commercial pump markets. In municipal pump markets, competition focuses on performance to required specification, service and price. Competition in the water treatment component market focuses on product performance and design, quality, delivery and price. In the pool and spa equipment market, there are a number of competitors with one that the Company considers its major competitor. The Company competes by offering a wide variety of innovative and high quality products which are competitively priced. Its existing distribution channels and reputation for quality also contribute to its continuing market penetration.

Description of the Electrical and Electronic Enclosures Segment: Products; markets; competition

Products include metallic and composite enclosures and cabinets that house and protect electrical and electronic controls, instruments, and components,components. These enclosures include cabinets, cases, subracks and microcomputer packaging systems, as well as a full line of accessories including backplanes and power supplies, and technical workstations.supplies. Products manufactured fall within two broad groups, standard and modified standard products and custom-designed products.

The products are sold in the United States, Canada, and overseas under the brand names Hoffman, Schroff, Transrack, Optima, Eraba, Electronic Enclosures, Pentair Enclosures and Pentair Enclosures. Electronic Packaging.

Segment products are sold in three primary markets: electrical enclosures in North America, the channel which is primarily served through industrial electrical distribution; electronic enclosures throughout the world, sold primarily through electronic equipment distributors and to original equipment manufacturers (OEMs); and information and communication technology (ICT) products throughout the world, marketed primarily to OEMs. The company is increasingly focusing efforts on serving the latter two faster- growingfaster-growing markets in the US and abroad both through acquisition (the former Walker Dickson and WEB), reorganization of certain businesses (Pentair Electronic Packaging) and through modified standard and custom-designed products.

Industrial markets include manufacturing industries in which electrical and electronic controls require protection from harsh factory floor environments,environments; plant maintenance and repair,repair; commercial constructionconstruction; and electrical equipment manufacturers. Commercial electronic markets include computer, test and measurement, industrial control and factory automation and medical industries. Finally, ICT products are found in the LAN, data communicationdatacom and telecommunicationtelecom industries.

Competition in product markets can be very intense, especially in electronic and ICT markets.markets, where product design, prototyping, global supply and customer service are very significant factors. Finally, growth in the EEE segment will likely come from development of distribution,continued channel penetration, growth in defined modification product offerings, product development, geographic expansion and acquisitions. CompetitionConsolidation, globalization and outsourcing are the most important trends in the faster-growing electronic enclosure business. The Company has made several acquisitions in the past few years in this area. The globalization of product demand increasingly requires world-wide local supply capability; no one competitor (including the EEE segment businesses) has successfully established that capability, although each of the three product markets focusesmajor competitors in this market is actively pursuing geographic extension for customer support purposes. In addition to these competitors, there exists a large number of regional suppliers whose capabilities are focused more on price, product features and innovation, service, quality and delivery. small runs of specialized build-to-print products.

Information Regarding All Segments: Status of new products.

The industries in which the segments participate are essentially mature and do not experience the introduction of new products or technologies that materially change the nature of the industry. Nonetheless, new product development or improvement becomes more important for sales growth and channel penetration. The Company emphasizes product development in all its segments; products introduced within the last five years average 30% of company-wide annual sales. No single new product constitutes a material amount of sales.

Raw materials.

The raw materials used in Pentair'sPentair’s manufacturing processes include steel (bar and sheet), brass, copper, aluminum and various other metals and plastics. Selected motors, castings, plastic parts and components are also purchased. The supply of all raw materials and components is currently adequate. The PTE and WFT segments import a significant dollar amount of selected products and components from Taiwan and China, the supply of which is also currently adequate.

Patents, trademarks, licenses, franchises and concessions. Pentair's

Pentair’s businesses own a number of U.S. and foreign patents and trademarks. They have been acquired over many years and relate to many products and improvements. No single patent or trademark is of material importance to any segment, though patentintellectual property protection is a significant competitive tool in each of the segments.

Seasonal aspects and working capital items. No material portion of Pentair's business is of a highly seasonal nature.

The PTE segment however, has historically experienced strong fourth quarter and weaker first quarter sales and billings, due in large part to holiday retail sales. Reflecting the somewhat seasonal impact of the PTE segment and the growing importance of home center business,retail sales, there is a buildup of inventory in the third quarter in anticipation of fourth quarter shipments. shipments, and growth in receivables in the fourth and the following first quarter of each fiscal year. In the WFT segment, the pool and spa equipment business is strongly seasonal. Peak sales are in the March-July time period. There are advance sales in earlier months but with long receivables terms. The August 1999 acquisition date for Essef meant that 1999 calendar results for Pentair do not show the benefit of the peak season for this business.

Dependence on limited number of customers.

The homecenters and mass retailers constitute the single most important distribution channel for the Company, however, the Company as a whole is not dependent on a single customer or on a few customers. The loss of a limited number of customers would not have a material adverse impact on the Company'sCompany’s results of operations. The single largest customer of the Company as a whole accounted for approximately 8%less than 10% of sales in 1998. 1999.

Backlog.

As of December 31, 1999, the Company had approximately $235 million in order backlog; substantially all of which are expected to be fulfilled by the end of 2000. As of December 31, 1998, the Company had approximately $135 million in order backlog; substantially all of which were fulfilled by the end of 1999. The increase in backlog is largely due to 1999 acquisitions and long-term orders with OEMs for Enclosure products.

Production and sourcing is geared towards providing adequate inventories in order to meet customer forecast requirements and minimize customer back orders. Therefore, order rates and inventory management are more significant factors than backlogs. For most of the Company’s businesses, backlogs are an indication of near-term demand, but are generally subject to cancellation by the customer. Other than for some municipal water system pumps, the segments normally have few products with long lead times. The natureWith the addition of the businesses emphasizes maintaining inventories sufficient to satisfy customer needs on a timely basis. Productionpool and sourcing is geared towards providing adequate inventoriesspa equipment products, certain advance sales are made in order to minimize customer back orders. Accordingly, backlogs are not material to understanding the sales trends or manufacturing fluctuations of the segments. fourth quarter.

Government contracts.

The Company has no significant portion of sales under federal government contracts that may be subject to renegotiation of profits or termination of contracts at the election of the government.

Research and Development. Pentair'sdevelopment.

Pentair’s businesses have not historically undertaken any significant basic or applied research, since the products and processes involved are moreinvolve traditional andtechnologies which are well known to all competitors. As discussed above, however, each of the segments, especially PTE, undertakes extensive product development and design work in order to continuedrive improvements in features and manufacturing costs. Overall, Pentair'sPentair’s businesses spent over 1.2%1.1% of sales on such development in 1999, 1998 and 1997. See also Note 1 of Notes to the Consolidated Financial Statements included in Item 8.

Management believes that its owned and leased facilities are well maintained and suitable for the operations conducted.

Item 3. Legal Proceedings.

The Company or its subsidiaries have been made parties to a number of actions filed or have been given notice of potential claims relating to the conduct of its business, including those pertaining to product liability, environmental, safety and health, patent infringement, and employment matters. Major matters that may have an impact on the Company are discussed below. The Company believes that the outcome of such legal proceedings and claims will not have a material adverse effect on the Company'sCompany’s financial position, liquidity, or future results of operations, based on current circumstances known to the Company.

Environmental Claims. The Company and its current subsidiaries have been named as defendants, targets or potentially responsible parties (PRPs) in a small number of environmental cleanups, in which the Company or its current or former business units have generally been given de minimis status. None of these claims have resulted to date in cleanup costs, fines, penalties or damages in an amount material to Company'sthe Company’s financial condition or results of operations. The Company has disposed of a number of businesses over the past ten years; in certain cases, such as the disposition of Company'sCompany’s Cross Pointe Paper Corporation uncoated paper business in 1995 and the disposition of its Federal Cartridge Company ammunition business in 1997, the Company has retained responsibility for some or all environmental obligations and potential liability. The Company has established what it believes to be, based on current circumstances known to it, adequate accruals for potential liabilities arising out of these retained responsibilities.

In addition to retained obligations relating to these disposed operations, there are pending environmental issues concerning a site in Jackson, Tennessee, on which the state environmental agency has opened an investigation. The Company acquired the site from Rockwell International Corporation, with whom the Company has agreed on division of responsibility for remediation and other future costs relating to the site. The Company does not believe, however, that projected response costs, as currently known, will result in material liability or material changes in operations.

Product Liability Claims. As of March 1, 1999,February 28, 2000, the Company or its subsidiaries are defendants in approximately 127 111

10


product liability lawsuits and have been notified of approximately 179191 additional claims. The Company has had and currently has in place insurance coverage it deems adequate for its needs. A substantial number of these lawsuits and claims are insured and accrued for by Penwald Insurance Company ("Penwald"(“Penwald”), a regulated insurance company wholly owned by the Company. See discussion in Item 7 (Management's(Management’s Discussion && Analysis - -Insurance— Insurance Subsidiary) and Item 8 (Note 1 of Notes to the Consolidated Financial Statements - Insurance Subsidiary). Accounting accruals covering the deductible portion of liability claims not covered by Penwald have been established and are reviewed on a regular basis. The Company has not experienced unfavorable trends in either the severity or frequency of product liability claims.

Horizon Litigation. Twenty-eight separate lawsuits involving 29 primary plaintiffs, a class action and claims for indemnity by Celebrity, were brought against Essef Corporation and certain of its subsidiaries which concern alleged exposure to Legionnaires bacteria by passengers aboard the cruise ship M/V Horizon, a ship operated by Celebrity Cruise Lines. The lawsuits included a class action brought on behalf of all passengers aboard the ship during the relevant time period, individual “opt-out” passenger suits, and a suit by Celebrity Cruise Lines, Inc.

The claims against Essef and its involved subsidiaries, are 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 bacteria that infected certain passengers on cruises from December, 1993 through July of 1994.

A settlement was reached in the class action litigation whereunder Essef agreed to pay monetary damages in the aggregate amount of $575,000 and Celebrity agreed to provide class members with coupons and other non-monetary consideration valued at approximately $1.2 million.

Essef and Celebrity have jointly attempted to resolve claims brought by “opt-out” plaintiffs. To date, eleven of these claims have been settled, for nominal amounts, leaving 18 primary plaintiffs. Essef and Celebrity have borne the cost of these settlements equally, subject to later allocation. The first trial for a primary plaintiff has been set to start on May 1, 2000.

Celebrity Cruises, Inc. is alleging that it has sustained economic damages due to loss of usage of the M/V Horizon while it was dry docked.

Claims asserted against Essef and the other defendants, in aggregate, exceed $200 million. However, trial counsel is optimistic that all of the pending suits will be resolved within available insurance coverage.

Essef’s insurance carriers are presently defending the Horizon litigations subject to a reservation of rights, and they have filed a Declaratory Judgment action to determine to what extent they have responsibility for making payments in the event Essef is found liable.

Patent Infringement Claims. In late 1998, The Black && Decker Corporation ("(“Black & Decker"& Decker”), a competitor of the Company in its PTE segment, commenced litigation against the Company'sCompany’s Porter-Cable business claiming patent infringement over the new Porter-Cable plate joiner. In order to minimize the likelihood of future claims, Porter-Cable changed the design of the plate joiner involved shortly after its introduction. At trial, Black && Decker sought $14 million in compensatory damages and removal of the plate joiner from the market. In late February 1999, the jury found for Black && Decker on a limited number of its claims and awarded $1 million in damages. Porter- Cable intends toPorter-Cable filed an appeal from the judgment, as it believesbelieved that there was no infringement of the Black && Decker patent at issue. The Company understands that Black & Decker will likely also appeal this case. In order to minimize the liklihoodwas denied in January of future claims, Porter-Cable changed the design of the plate joiner involved shortly after its introduction. 2000.

Management’s Discussion and Analysis

Strategic Direction

Pentair grows its businesses through innovative marketing and product design and intensive productivity improvement, coupled with capital investment, and employee training and participation. Pentair has chosen to focus these skills on its three core markets of Professional Tools and Equipment (PTE), Water and Fluid Technologies (WFT), and Electrical and Electronic Enclosures (EEE). During the last fourfive years, Pentair has divested its paper businesses (1995) and Federal Cartridge (1997) and has made twelvefifteen acquisitions in its three core markets.

Beginning in 1999, the cost of certain support services provided by the corporate office is no longer reflected in the “Other” segment and is allocated to the operating segments. As a result, the prior years segment information has been restated to conform to the 1999 presentation with no effect on previously reported total operating income, net income or shareholders’ equity.

* Other includes corporate leadership expenses, captive insurance company, intermediate financial companies, charges that do not relate to current operations, divested operations (Federal) and intercompany eliminations.
 
** Including net restructuring charge of $38 million taken in 1999. Before restructuring charge, operating income for the segments and for Pentair as a whole were: PTE — $122,170; WFT — $85,731; EEE — $63,089; and Pentair total — $252,331.

CONSOLIDATED
1999 VERSUS 1998

Consolidated net sales increased over 1998 levels to current operations, divested operations (Federal)$2,367.8 million in 1999, or 22.2%, attributable in part to healthy markets as well as three acquisitions in 1999. Net sales in each of the three segments increased over 10% for the full year, with the largest increase posted by PTE. For the fourth quarter of 1999, sales growth accelerated dramatically, with consolidated net sales up 49.8% over the prior year quarter. This growth was significantly enhanced by the third-quarter acquisitions of the Essef and intercompany eliminations. CONSOLIDATED DeVilbiss Air Power businesses, with WFT up 63.9% and PTE up 56.9%; while, excluding

14


acquisitions, sales growth in the fourth quarter was over 9% for Pentair as a whole, with each of the three segments contributing impressive increases.

Operating income increased $21.1 million to $214.3 million in 1999, up 10.9% over 1998, after the restructuring charge, and increased by $59.1 million or 30.6% over 1998, excluding the charge. Operating income before acquisitions increased over 20% compared to 1998 performance. Return on sales was 9.1% after the restructuring charge and 10.7% excluding the charge. Profitability (before the charge) improved due to volume and other manufacturing efficiencies, material cost savings, offset in part by continuing pricing pressures, increasing employment costs, costs of special selling programs and other sales expenses. Gross profit margins declined to 31.0% in 1999 versus 31.3% in 1998, largely attributable to the 1999 acquisitions. Excluding acquisitions, gross margins improved by 130 basis points year-over-year. Research and development declined slightly in percentage terms to 1.1% from 1.2% of net sales in 1998. Selling, general and administrative expense (SG&A) as a percent of sales was 19.3% in 1999 as compared to 20.2% in 1998.

Fourth-quarter operating income increased 58.1% to $91.6 million over the same period in 1998; even without the benefit of the 1999 acquisitions, operating income for the quarter increased dramatically by over 30%. Return on sales in the quarter improved to 11.7%, largely as a result of the acquisitions, volume and other manufacturing efficiencies and material savings.

Interest expense was significantly higher in 1999 and in the fourth quarter as compared to the same periods in 1998, due primarily to much higher borrowings incurred in connection with the 1999 acquisitions.

The Company’s effective income tax rate was 38.0% in 1999, an increase from the comparable 1998 rate of 37.5%. A one percent improvement to 36.5% (reflected in the first two quarters) was more than offset by the impact of non-deductible goodwill incurred as a result of the acquisitions of the three businesses in 1999.

Net income decreased slightly to $103.3 million in 1999 from $106.8 million in 1998, including the $38 million ($24.1 million after-tax) restructuring charge in 1999. Net income before the charge was $127.4 million, or an increase of 19.3%. Net income in the fourth quarter was up 30.5% to $43.0 million. Full-year EPS was $2.33 compared to $2.46 in 1998 after the restructuring charge; excluding the restructuring charge, EPS increased 17.5% to $2.89. Fourth-quarter EPS in 1999 increased 18.4% from $.76 to $.90.

1998 VERSUS 1997
Consolidated net sales increased to $1,937.6 million in 1998, representing a 5.4% increase over 1997(up over 13% excluding the 1997 sales of Federal Cartridge, divested in November 1997). PTE and WFT posted double-digit growth rates, with the latter including the full year effect of a 1997 pump business acquisition. EEE segment experienced lower sales due to soft capital spending environments in the U.S. and the overall German and Asian economies.

Operating income increased to $193.2 million in 1998, up 13.8% over 1997, which as a percent of sales improved from 9.2% to 10.0%. Profitability improved due to volume efficiencies, favorable outsourcing opportunities, and manufacturing/purchasing efficiencies resulting from the integration of acquired pump businesses. Gross profit margins improved to 31.3% in 1998 versus 29.8% in 1997. Research and development expenses were 1.2% of net sales versus 1.2% in 1997. Selling, general and administrative expense (SG&A)&A) as a percent of sales was 20.2% in 1998 as compared to 19.4% in 1997. The Company continues to incur costs to support major information system upgrades (which are starting to be offset by the associated cost improvements) and expenses were incurred to implement company-wide process improvement and cost savings programs with benefits beginning in 1999.

Interest expense was higher in 1998 as compared to 1997 due to slightly higher effective interest rates.

The Company'sCompany’s effective income tax rate was 37.5% in 1998. The comparable 1997 tax rate (excluding the unusual tax impact on the sale of Federal) was 39.0%.

Net income increased 16.6% to $106.8 million versus $91.6 million in 1997. EPS of $2.46 in 1998 represented an increase of 16.6% over 1997 EPS of $2.11. Excluding the $0.03 gain from the sale of Federal in 1997, there was an 18.3 percent increase over 1997. 1997 VERSUS 1996 Consolidated net sales increased to $1,839.1 million in 1997, representing a 17.4% increase over 1996. The double-digit growth rate is attributable to additional strategic acquisitions and continued growth in North America. Outside of North America, difficult European markets and weak local currencies limited the growth of sales in dollar terms. Operating income increased to $169.8 million in 1997, up 18.8% over 1996. Operating income as a percent of sales improved slightly from 9.1% to 9.2%. Significant margin gains in most existing businesses were nearly offset by the lower operating margins of our recent acquisitions. Strategic investments were made throughout all the operating segments to position the Company for continued productivity gains, increased capacity and improved customer service and satisfaction. Gross profit margins were maintained, remaining nearly flat at 29.8% in 1997 versus 29.9% in 1996. Research and development expenses increased to 1.2% of net sales versus 1.0% in 1996 due to the increasing stream of new products. Selling, general and administrative expense (SG&A) as a percent of sales was 19.4% in 1997 as compared to 19.8% in 1996. The Company continued to incur costs to support major information system upgrades, which are starting to be offset by the associated cost improvements. Interest expense was higher in 1997 as compared to 1996 due to slightly higher effective interest rates and higher average outstanding debt levels in 1997, influenced by the acquisition of the pump business in August and the sale of Federal in November. Pentair sold its Federal Cartridge Company to Blount International, Inc., in November 1997, realizing a $10.3 million pre-tax gain. This gain was reduced by $9.1 million of taxes, resulting in a net gain of $1.2 million, or $.03 per share. Sales and operating income for Federal through the first 10 months of 1997 improved over the levels of their very difficult 1996. Taxes on the gain from the sale of Federal were greater than the Company's normal tax rate due to non-deductible goodwill created as part of the original structure of the 1988 Federal-Hoffman acquisition. The Company's effective income tax rate of 42.2% includes this incremental tax from the gain on sale. The tax rate excluding the gain on the sale of Federal was 39.0% as compared to 40.2% in 1996. Net income increased 22.9% to $91.6 million versus $74.5 million in 1996. EPS of $2.11 in 1997 represented an increase of 22.0% over 1996 EPS of $1.73. EPS without the gain from the sale of Federal was $2.08, a 20 percent increase over 1996.

OUTLOOK

Pentair is focused on three core markets. This diversification enables the Company to consistently improve results despite difficult markets in one or another segment. Continuing demand for power tools and service equipment, ever-rising needs for clean water throughout the world, and the critical importance of protecting sensitive electronics give Pentair'sPentair’s chosen businesses excellent prospects for strong long-term performance. The Company'sCompany’s basic operating strategies - ongoing cost containment, new product development, multi-channel distribution, and the pursuit of value-added acquisitions - drive the businesses in both growing and softer economies. The Pentair Accelerating Competitive Excellence (PACE) Project is afocusing on implementation of its corporate-wide process redesign and cost savings program implementedprograms initiated in 1998 which management believes will continue to improve operating efficiencies and therefore performance.

Pentair began implementation in 1999 of a program to consolidate a number of its businesses into larger, more effective units which will be better positioned to compete in their respective markets. Pentair’s tool businesses, Porter-Cable and Delta, will consolidate their operations in the first quarter of 2000, following an earlier combination of their sales organizations. Also underway in 1999 and to be completed in 2000 is the consolidation of two service equipment businesses (Century and Lincoln Automotive), including the closing of one manufacturing facility. The tool businesses also have completed construction of a new 650,000 square foot warehouse facility in Jackson, Tennessee. The warehouse is expected to go into full operation in the first quarter of 2000, when two smaller warehouses for Delta and Porter-Cable will close.

The acquisition of Essef in August 1999 has increased the complexity and opportunities in the WFT businesses. Pentair has closed one of the acquired facilities and relocated manufacturing operations; over the next few quarters, Pentair intends to continue reorganization and consolidation of units in order to improve manufacturing efficiencies and financial performance.

In addition, the Company’s EEE segment combined five separate North American facilities into one business, Pentair Electronic Packaging, in order to focus on the high-growth custom and modified enclosure market for datacom and telecom products.

The Company continues to look for synergistic acquisitions in each of its business segments, in line with its pattern over the past fourfive years. Of the past twelvefifteen acquisitions made since 1994, most were smaller businesses or product lines, which fit with existing operations, offering new products or expanded geographic scope. Two,Three recent transactions in 1997 and 1999, however, were stand-alone strategic acquisitions of large established businesses, that helped create Pentair's Watertwo in Pentair’s WFT segment (General Signal Pump Group and Fluid Technologies segment.Essef) and one in its PTE segment (DeVilbiss Air Power Company). Pentair intends to continue to pursue smaller, bolt-on purchases, but will also carefully review larger targets whichthat have the capability to significantly expand its current segments, or in appropriate cases, tothat establish an additional business segment.

SEGMENT DISCUSSION

Pentair operates in three segments: Professional Tools and Equipment (PTE), Water and Fluid Technologies (WFT), and Electrical and Electronic Enclosures (EEE).

PROFESSIONAL TOOLS and EQUIPMENT

The PTE segment includes Delta International Machinery, Porter- Cable, Lincoln Automotivethe tool businesses (Delta and Century Manufacturing.Porter-Cable); and the equipment businesses (Century and the newly-acquired DeVilbiss Air Power Company). Products manufactured include woodworking machinery, portable power

16


tools, battery charging and testing equipment, welding equipment, and lubricating and lifting equipment. equipment, air compressors, generators and pressure washers.

1999 VERSUS 1998

Net sales increased substantially in 1999, from $849.3 million to $1,073.8 million, or 26.4%. Net sales in the fourth quarter increased 56.9%. The DeVilbiss Air Power Company acquisition accounted for a significant portion of the sales increase. The increase in internal growth in 1999 is attributable in large part to continued innovation and new product introductions by each of the businesses in this segment.

PTE operating income for the year increased to $105.4 million, after the restructuring charge, or 5.8%. Excluding the restructuring charge, operating income was $122.2 million, or an increase of 22.6%. For the fourth quarter, operating income for the segment was $50.8 million or 33.0% better than 1998, attributable to the DeVilbiss Air Power Company acquisition. Both full-year and fourth-quarter operating income for the segment was unfavorably impacted by two factors: one-time costs not covered by the restructuring charge incurred as a result of the consolidation of operations as well as severe competitive pressures for certain automotive and service products.

Segment return on sales (before restructuring charge) was down 30 basis points to 11.4% for the full year, although operating margins for the segment excluding acquisitions was comparable to the 11.7% recorded for 1998. Segment return on sales after the restructuring charge was 9.8%. For the fourth quarter, return on sales for the entire segment was 12.6% compared to 14.8% in the same period in 1998, attributable in part to the new acquisition.

1998 VERSUS 1997
PTE sales increased by $102.2 million or 13.7%. These businesses continue to outperform their markets, upholding a performance record that includes three consecutive years of double-digit sales growth and five consecutive years of double-digit operating income growth. The tool businesses continued to introduce innovative new products such as a plate joiner and jigsaw and expanded its offering of pneumatic nailers, staplers and accessories. The service equipment business increased sales of Booster Pacs and expanded its automotive offering with the product line acquisition of T-Tech automatic transmission fluid exchangers.

Operating income as a percent of sales increased to 12.7%11.7% in 1998 from 11.3%10.3% in 1997. Profitability increased in the tool business due to favorable sourcing opportunities and volume efficiencies. Profitability also increased in the service equipment business due to productivity improvements and facility rationalizations. 1997 VERSUS 1996 PTE sales increased by $164.4 million or 28.2%. The full year effect of 1996 acquisitions contributed to less than half of the growth in sales. Substantial growth was achieved in the tool business due to the introduction of new products, increased brand awareness and continued expansion of the home center channel. Operating income as a percent of sales increased to 11.3% in 1997 from 10.4% in 1996. Profitability improved across the entire segment due to volume efficiencies, cost control activities and continued productivity improvement.

OUTLOOK

The Professional Tools and Equipment segment is expected to perform well in 1999 withcontinue to realize sales growth expected to continue toin 2000, both as a result of the DeVilbiss Air Power Company acquisition and, more importantly, continued organic growth as a result of continued new product introductions and increased cross-selling of products, including acquired products, across all major distribution channels. Operations will be adversely impacted for the first half of 2000 as a result of continuing one-time costs for consolidations of segment business units and start-up costs at the new Jackson, Tennessee distribution center. Nonetheless, Pentair expects continued improvement in operating margins and income throughout the double digits due to product line expansionscoming year, as a result of the acquisition and continued cross marketing through multiple channels of distribution. Profits should increase due to process improvementsother manufacturing, purchasing and additional rationalization activities. distribution efficiencies.

WATER and FLUID TECHNOLOGIES

The WFT segment includes the Pentairpump and pool businesses (Pentair Pump Group and one of the newly-acquired Essef businesses), the water treatment businesses (Pentair Water Treatment which consists of Fleck Controls plus the remaining Essef business) and Lincoln Industrial. Products manufactured include pumps for wells and water treatment, sump pumps, pool and spa equipment such as valves, pumps, filters, lights and related equipment, valves and pressure

17


vessels for water softeners,treatment products and automated and manual lubrication systemssystems.

1999 VERSUS 1998

Net sales increased substantially in 1999, from $537.9 million to $669.6 million, or 24.5%. The Essef acquisition accounted for the majority of the increase for the year. Net sales in the fourth quarter increased 63.9%, with organic growth accelerating to over 6% of prior-period sales.

WFT operating income for the year increased to $81.3 million, after the restructuring charge, or 23.2%. Excluding the restructuring charge, operating income was $85.7 million, or an increase of 29.9% and equipment. excluding acquisitions, operating income increased nearly 20%. For the fourth quarter, operating income for the segment was $25.5 million or 50.5% better than 1998, while excluding acquisitions, operating income was up over 30% from the prior year. Both full-year and fourth-quarter operating income for the segment increased as a result of supply management initiatives and strong labor productivity.

Segment return on sales (before restructuring charge) improved 50 basis points to 12.8% for the full year, although operating margins for the segment excluding acquisitions increased over 200 basis points over 1998. Segment return on sales after the restructuring charge was 12.1%. For the fourth quarter, return on sales for the entire segment was 12.1%, down from the year-earlier quarter which was 13.2%. This decrease is entirely attributable to the Essef acquisition; excluding acquisitions this segment’s return on sales for the period increased nearly 300 basis points.

1998 VERSUS 1997

WFT sales increased by $133.9 million or 33.1%, primarily due to the full year effect of the 1997 pump business acquisitions; internal growth accounted for approximately 5% of the sales increase. Net revenues were adversely impacted in part by the deliberate elimination in 1998 of the unprofitable sales from the Layne && Bowler product line, acquired as part of the General Signal pump acquisition in 1997.

Operating income as a percent of sales increased to 13.3%12.3% in 1998 from 11.4%10.4% in 1997. The Group'sGroup’s performance benefited from improved performance at the water conditioning control valve business, increased profitability at European operations, and over $10 million worth of manufacturing and purchasing efficiencies resulting from the integration of the acquired pump businesses. 1997 VERSUS 1996 WFT sales increased by $81.7 million or 25.4%, primarily due to acquisitions. In particular, 1997 results included 4 months of operations from the pump businesses purchased from General Signal. Otherwise, this segment experienced moderate growth, dampened by the effects of

OUTLOOK

As a stronger U.S. dollar on the resultsresult of the EuropeanEssef acquisition, the WFT segment greatly expanded its product and geographic capabilities. The segment plans to focus more resources on its growth in overseas markets, especially by Pentair Water Treatment, while continuing to implement its operating improvement initiatives previously adopted and while integrating the newly acquired businesses into its ongoing operations. Operating income asAs a percentresult of sales decreasedthe increasing importance of the water markets to 11.4% in 1997 from 13.8% in 1996. 1997 acquisitions had lower margins than the overall 1996 percentage for this segment. In addition, one plant experienced temporary production difficulties in meeting customer demand. Investments were made in 1997 across the segment addressing plant and product rationalization, process redesign, and production capacity. Profitability was also impacted byfollowing the weak European economy and the effects of a stronger U.S. dollar.

Volume efficiencies and productivity improvements are anticipated to continue to generate higher margins in core markets. Lincoln Industrial business.

ELECTRICAL and ELECTRONIC ENCLOSURES

The EEE segment includes Hoffman Enclosures, Schroff, Pentair Electronic Packaging (a newly-integrated North American enclosures business, comprised of Schroff US, the newly-acquired WEB and the newUS affiliates of the former Walker Dickson business) and Pentair Enclosures U.K. acquisition. Products manufactured include metallic and composite cases, subracks and cabinets that house and protect electrical and electronic controls, instruments and components.

1999 VERSUS 1998

Net sales increased 12.3% in 1999, to $633.7 million, most of which is attributable to the 1998 acquisition of Walker

18


Dickson and the 1999 acquisition of WEB. Overall net sales in the fourth quarter increased 22.0%, with internal growth up nearly 15% from prior-period sales. The improvement in internal growth in the fourth quarter was largely attributable to expanded distribution in North America of standard electrical enclosure products and increased penetration into the faster-growing datacom and telecom product markets, as well as accelerating growth of standard electronic enclosures in Europe. Fourth quarter sales in local currency in Europe improved 18% quarter-over-quarter, although in US dollar terms the growth amounted to 8%.

EEE operating income for the year after the restructuring charge increased slightly to $46.3 million. Excluding the restructuring charge, however, operating income improved 37.1% and operating income, excluding acquisitions, increased over 45%. For the fourth quarter, operating income for the segment was $19.9 million or 149.9% better than 1998, while excluding acquisitions, operating income was up nearly 200% from the prior year.

Segment return on sales (before restructuring charge) improved significantly for the full year, from 8.2% to 10.0%, although operating margins for the segment excluding acquisitions increased nearly 360 basis points over 1998. Segment return on sales after the restructuring charge was 7.3%. For the fourth quarter, return on sales for the entire segment was 11.5%, up dramatically from the very weak year-earlier quarter which was only 5.6%. Excluding acquisitions, however, the increase was even stronger, which is largely attributable to vastly improved performance at the European enclosure businesses and to strong performance of all of the North American businesses.

1998 VERSUS 1997

EEE sales decreased $15.3 million or 2.6%. Enclosures Americas sales were lower in 1998 largely due to lower automotive and machine tool capital spending. Enclosures Europe sales also decreased due to slow sales of standard product throughout Europe, while Enclosures Asia sales were below 1997 due to the weak Asian economy. With the October 1998 acquisition of Pentair Enclosures U.K., Pentair strengthened its position in markets serving high-growth manufacturers in information and communication technology markets.

Operating income as a percent of sales was flat at 9.2%8.2%, the same overall profitability as 1997, despite a decrease in sales. Enclosures Americas increased profits due to overhead reductions and repositioning of the sales force to focus on high growth customers and leverage modification capabilities. Enclosures Europe earnings declined in part due to lower volumes and unfavorable product mix throughout Europe. In addition, the closing of one facility in France and resultant headcount reductions were delayed by a lengthy government approval process until the fourth quarter of 1998. Enclosures Asia profitability decreased due to the weak Asian economy. 1997 VERSUS 1996

OUTLOOK

Pentair plans to continue process improvement and reorganization at all of the businesses in the EEE sales increasedsegment. While no further significant headcount reductions are currently planned, the expansion of the enclosure businesses around the world will be critical to the segment’s future success in the rapidly expanding datacom and telecom fields, especially in creating a world-wide capability to serve these markets, whether in the Americas, Europe or Asia.

SPECIAL RESTRUCTURING CHARGE

In the first quarter of 1999, the Company recorded a special restructuring charge of $38.0 million ($24.1 million after-tax or $.56 per share). As shown below, $12.8 million has been spent or charged through December 31, 1999. The remaining balance is classified within Accrued Liabilities and Other Expenses on the balance sheet.

The restructuring plan comprises consolidation of certain operations, overhead reductions, and outsourcing of specific product lines in each of the Company’s three business segments. Pentair anticipates a reduction of approximately 1,050 jobs, as detailed below, offset by $30.6 million or 5.6% including a 1997 acquisition. In addition,approximately 350 new jobs at other Pentair facilities in connection with consolidation and rationalization. The restructuring plan does not contemplate the Company exiting any of its current lines of business; the projects involved are designed to make the Company’s existing businesses more efficient.

The Professional Tools and Equipment segment is consolidating North American sales weredistribution operations and combining the highestheadquarters of the two power tool businesses, Delta and Porter-Cable, in history and outpacedJackson, Tennessee. In the overall growthservice equipment businesses, products are being outsourced to offshore manufacturers or transferred to other North American facilities. The Jonesboro, Arkansas manufacturing operation of Lincoln Automotive will be closed. These actions will result in the markets served. termination of more than 600 employees. Restructuring charges for this segment amounted to $16.8 million, $10 million of which is attributable to employee terminations, and the balance of which relates to asset write-downs and other exit costs. Management estimates the benefits under the restructuring plan will be approximately $16 million in 2000 and $15 million in 2001.

The European operations, as measuredWater and Fluid Technologies segment has reduced the workforce at its Lincoln Industrial business and is outsourcing some product manufacturing, resulting in local currencies, also experienced year-over-year sales growth despite a continued weak economy in Europe. However, European sales (excluding acquisitions), as measured in a stronger U.S. dollar, were less than 1996. Operating income as aheadcount reductions of approximately 100 employees. Lincoln Industrial plans to eliminate approximately 50 percent of sales decreasedthe manufacturing space at its U.S. manufacturing facilities. The charge for this segment was $4.5 million, approximately $1.2 million of which relates to 9.2%terminated employees, and the balance of which is attributable to demolition and other exit costs. Management estimates the benefits under the restructuring plan will be approximately $2 million in 1997 from 10.9%2000 and $2 million in 1996.2001.

The Electrical and Electronic Enclosures segment reduced its workforce in Europe and adopted a plan to rationalize manufacturing at its North American facilities. These actions will result in the reduction of approximately 350 employees. This was duesegment absorbed $16.7 million of the charge, largely related to employee terminations. Management estimates the benefits under the restructuring plan will be approximately $9 million in 2000 and $12 million in 2001.

Remaining Reserve$18.1$4.0$3.1$25.2




“Personnel Costs” consists of severance, medical plan continuation, pension cash-outs, and outplacement per company policy for the 1,050 employees planned to be terminated. As of December 31, 1999, approximately 400 employees have been terminated (or in Europe are working under statutory notice periods).

“Asset Disposals” consists of the write-down of the carrying value of the Delta headquarters building which is held for resale and the write-off of special-use manufacturing and support assets which will no longer be needed and which will be scrapped or abandoned. The real estate held for resale is expected to be disposed of by mid-2000. All of these assets are currently classified as property, plant and equipment. No charge has been taken with respect to the impactJonesboro real estate since the Company believes it will be able to be sold for book value within a reasonable period.

“Exit Costs” consists of maintenance and security costs of surplus buildings until leases expire or demolition or disposal of certain buildings, including the Jonesboro building.

“Personnel Costs” and “Exit Costs” are cash costs and the “Asset Disposals” are primarily non-cash costs. Our currently anticipated schedule projects cash expenditures of $19 million in 2000 and $2 million in 2001. These requirements will be funded through cash from operations or borrowings under our existing credit facilities.

During 1999, restructuring benefits (largely personnel cost savings) of approximately $6 million were realized. Anticipated benefits are projected to be $26 million in 2000 and $30 million in 2001. The major components of anticipated benefits are

in reductions in labor costs and efficiencies in consolidating distribution and administrative functions.

The anticipated benefits noted above are net of the weak European economy, with intense competition affecting pricing and product mixcosts of sales. There were also strategic,adding 350 employees at other Pentair locations. The benefits do not, however, take into account one-time costs relatedassociated with these restructuring plans. The Company anticipates that the associated one-time costs will amount to the following: implementationapproximately $6 million, one-quarter of a new world-wide business system; start-upwhich was incurred in 1999, with most of the new 300,000-square-foot production facility in Mt. Sterling, Kentucky; integration of the Transrack acquisition including reorganization of the French sales and marketing activities; the cost of employment reductions in Europe; introduction of outdoor enclosures for the telecommunications market; and start up of the North American manufacture of a new flagship product, the ProLine enclosure. OUTLOOK The EEE segment holds a leading positionbalance to be incurred in the global enclosures marketfirst quarter of 2000. These costs are not included in the restructuring charge, since they relate to asset relocations, start-up costs and has excellent prospects for growthtraining and profitability improvement as the business positions itself to continue leadershiprecruiting of employees at other locations.

Liquidity and Capital Resources

The Company incurred approximately $800 million of indebtedness in standard product markets and expand offering of modified product. The recent acquisition of Pentair Enclosures U.K. has increased the focus and ability to provide custom products and serve the fast growing telecom and datacom customers. The EEE segment is implementing a number of changes in its operations1999 in order to control costs, improve productivitycomplete the acquisitions of Essef and respond more flexiblyDeVilbiss Air Power. As a result of these borrowings, Pentair’s total debt to its customers. Actions to be taken will likely include some facility rationalization and headcount reductionscapital ratio at the end of the third quarter of 1999 was 63%. Following the successful common stock offering in October 1999 and beyond. Liquidity and Capital Resources The Company's freeapplication of cash flow (cash from operations lessin the fourth quarter, the Company’s total debt to capital expenditures)ratio was $81.551% at December 31, 1999. This compares with a 33% total debt to capital ratio at the end of 1998. The Company has targeted a total debt to capital ratio in the range of 30% to 40% as appropriate for its financing needs and current business plans, although Pentair will exceed this target ratio from time-to-time as needed for operational purposes and/or acquisitions.

Of the total indebtedness of the Company at the end of 1999, more than 85% (approximately $885 million, including $27.2 million in 1998, upcurrent maturities) is long-term and has an average life to maturity of 6 years. This long-term indebtedness has interest rates varying from $40.4 million in 1997. The Company is targeting continued growth in free cash flow as a percent4.0% to 9.0%, with an average interest rate of sales through improved profitability and working capital ratios.7.22%. The Company believes that currently outstanding long-term indebtedness is and will continue to be adequate for its financing needs for the foreseeable future. The Company also believes that it will be able to obtain additional long-term indebtedness as its needs may increase or its current indebtedness matures.

Short-term indebtedness (included in current maturities of long-term debt) stands at $150.6 million as of the end of 1999 with interest rates that range from 6.37% to 8.5%, with an average interest rate of 7.0%. The Company believes that it will generate substantial cash flow from operations and from any asset dispositions which will continuebe used in part to exceed its needs for capital programs, smaller acquisitions and dividends in the next year. The Company's financial position was strengthened in 1998, even taking into account the three acquisitions madereduce current indebtedness during the year. As of December 31, 1998, the long-term debt to total capital ratio was 29 percent, compared to 32 percent at the end of 1997.2000. The Company has sufficient financing capacityno reason to continuebelieve that it would not be able to renew its current acquisitionshort-term credit agreements, at the time of their expiration in August 2000. In addition, the Company has entered into a commercial paper program and to support its ongoing stock repurchase program.

INFLATION

The impact of inflation on the Company'sCompany’s results of operations is not considered material given the current inflationary outlook.

INSURANCE SUBSIDIARY

The Company'sCompany’s captive insurance subsidiary provides a cost effective means of obtaining insurance coverage for general and product liability, product recall, workers'workers’ compensation and auto liability. The insurance subsidiary insures directly and reinsures an admitted carrier. Loss reserves are established based on actuarial projections of ultimate loss.

ENVIRONMENTAL MATTERS

Under current laws and regulations, Pentair'sPentair’s obligations relating to environmental matters are not expected to have a material impact on the Company'sCompany’s operations, financial condition or operating results. Some subsidiaries face remediation

of soil and groundwater as a result of predecessors'predecessors’ or their own previous disposal practices. In addition, Pentair subsidiaries have been named as potentially responsible parties at a small number of Superfund or other sites being studied or remediated. Generally, the affected business has been deemed to be a de minimis defendant or its share of remediation costs has not been material to Pentair. Pentair contractually retained certain obligations pertaining to environmental issues of discontinued paper businesses and the divested sporting ammunition business. Costs and capital expenditures related to environmental obligations were not material to the Company'sCompany’s operations in either 19981999 or 1997,1998, and are not anticipated to be material in 1999. 2000.

Pentair engages environmental professionals to perform periodic audits of its facilities to assist Pentair in complying with the various environmental laws and regulations faced by its businesses. For purposes of maintaining appropriate reserves against liabilities associated with environmental issues, whether involving on- or off-site locations, Pentair management reviews each individual site, taking into consideration the number of parties involved with the site, the joint and several liability imposed by certain environmental laws, the expected level of contributions of the other parties, the nature and quantities of wastes involved, the expected method and extent of remediation, the estimated professional expenses involved and the time period over which any costs would be incurred. Based on this evaluation, reserves are established when loss amounts are probable and reasonably estimable. Insurance recoveries are recorded only when claims for recovery are settled.

YEAR 2000 Background

The Company pursued an extensive Year 2000 issue is theprogram in order to anticipate and correct Y2K computer problems. As a result of computer programs and embedded computer chips originally having been designed and developed using two digits rather than four digits to define the applicable year. Any of the Company's internal use computer programs and hardware as well as its products that are date sensitive may recognize a date using "00" as the Year 1900 rather than the Year 2000. This could result in a system failure or miscalculations causing disruptions of operations, including, among other things, a temporary inability to process transactions or engage in normal business activities for boththis program, the Company andsuffered only very minor computer-related problems at any of its customers who rely on its products. Statebusinesses in early 2000, all of Readiness The Company's businesseswhich have had "Y2K Project" programs in place since as long ago as 1995 to address Year 2000 problems in critical business areas for information management systems, non- information systems with embedded technology, suppliers and customers. The Company has largely completed its review and compliance planning for its critical information systems (IS). Certain of the Company's larger businesses have completed the implementation of required actions for compliance; the balance of the business units are in the process of implementation. In many cases, implementation includes installation of new Enterprise Resource Planning ("ERP") systems designed to enable these businesses to operate more efficiently and to provide better management reporting. Pentair anticipates that implementation and testing phases will be substantially complete throughout the company by the third quarter of 1999. The Company is also in the process of reviewing and replacing, where necessary, its other automated communications and manufacturing systems. The Company estimates that it will complete this phase by the second quarter of 1999. None of the Company's products are believed to be date dependent. The Company has close working relationships with a large number of suppliers and customers. These include, among others, utility and telecommunication providers, raw materials and components suppliers, and financial institutions, managed care organizations and large retail establishments. The Company has been reviewing, and continues to review, with its critical suppliers and major customers the status of their Year 2000 readiness. The Company's business units have established plans for ongoing monitoring of suppliers during 1999. Costs to Address the Year 2000 Issue corrected.

As a result of the numerous different ISinformation systems used by businesses that the Company has acquired in recentover the years and also as a result of changing business requirements, the Company has an ongoing development plan with scheduled replacements of hardware and software occurring in 1999over the past few years and continuing into the future throughout the organization. Year 2000 compliance iswas a by-product of ourthe Company’s information systems (IS) development plan. This plan calls for the installation or updating of new Enterprise Resource Planning (ERP) systems for its current manufacturing and headquarters locations designed to enable these facilities and the related businesses to operate more efficiently and to provide better management reporting. The estimatedCompany has already installed its ERP systems in 22 locations. The Company’s remaining manufacturing locations and businesses will be converted to the new ERP system over the next few years as the information system development plan progresses.

The costs specifically attributable to Year 2000 compliance, apart from other IS development activities, amounted to approximately $13 million. The cost associated with the total IS development plan over the five-year period from 1995 to 1999 is anticipatedwas approximately $60 million. The Company estimates that the cost to be approximately $55 million, which is approximately 80% complete. The estimated cost specifically attributableconvert the remaining facilities and businesses to Year 2000 compliance, apart from other IS development activities, amountsthe new ERP systems will amount to approximately $10$10-12 million of which $8 million had been spent through December 31, 1998. Pentair has not deferred any significant IS projects as a result of the implementation of the Y2K Project. Risks Represented by the Year 2000 Issue Pentair believes that completed and planned modifications and conversions of its internal systems and equipment will allow it to be Year 2000 compliant in a timely manner. However, there can be no assurance that the Company's systems or equipment, nor those of third parties on which Pentair relies, will be Year 2000 compliant , in all material respects, in a timely manner. Nor can Pentair give any assurance that its own or third parties' contingency plans will mitigatecompleted over the effects of any noncompliance. Pentair believes that non-compliance with Year 2000 issues would likely result in some reduction of the Company's operationsnext three to four years for the first partCompany’s current businesses. Acquisition or establishment of the year 2000, which could have a material adverse effect on the Company's businesses or their financial condition. Based on its assessments to date, Pentair believes it will not experience any material disruption as a result of Y2K issues in internal manufacturing processes, information processing, interfacing with major customers or processing orders and billing. However, if critical utility service providers experience difficulties, which affect Pentair, or itsnew business units a shutdownwould also require the conversion or updating of some or all operations at individual facilities could occur. Pentair is developing contingency plans to provide for continuity of processing (in the event of a Y2K disruption) which will be based on the outcome of its Y2K compliance reviews and the results of third party verification efforts. Assuming no major disruption in service from utility companies or similar critical third-party providers, Pentair believes that it will be able to manage its Year 2000 transition without material effect on Pentair's results of operations or financial condition. The most reasonably likely worst case scenario of failure by Pentair or its suppliers or customers to resolve Year 2000 issues would be a temporary slowdown or cessation of manufacturing operations at one or more of Pentair's facilities, and/or a temporary inability on the part of Pentair to timely process orders and to deliver finished products to customers. Delays in meeting customer orders would reduce or delay sales and affect the timing of billings to and payments received from customers and could result in complaints, charges or claims, or temporarily increasing working capital. Contingency Plans Pentair's businesses are in the process of developing Year 2000 contingency plans, based on their review of their internal and external compliance progress. A full review will be done following the end of the second quarter of 1999 to assess Pentair's vulnerability to internal non-compliance and potential third-party failures and actions which can be taken to reduce unfavorable impacts. Possible plans may include arranging alternative or additional suppliers and service providers, increasing inventory levels, providing additional back-upERP systems and replacing or upgrading equipment and software. THE EURO CONVERSION On January 1, 1999, eleven of the fifteen member countries of the European Union (EU) established fixed conversion rates through the European Central Bank (ECB) between their existing local currencies and the Euro, the EU's single currency. The participating countries have agreed to adopt the Euro as their common legal currency on that date; the Euro now trades on currency exchanges and be available for non-cash transactions. The Company is reviewing the Euro's impact on the Company's business and pricing strategies. The Company's European business units have made the necessary investments in their IS systems in order to be able to handle transactions in Euros, as requested. The introduction of the Euro is not expected to have a material impact on the Company's overall currency risk or its ability to transact business. necessary.

term debt. The table below presents principal cash flows and related weighted average interest rates of the Company'sCompany’s long-term debt at December 31, 19981999 by expected maturity dates. Weighted average variable rates are based on implied forward rates in the yield curve at December 31, 19981999 plus the Company'sCompany’s borrowing spread. Implied forward rates should not be considered a predictor of actual future interest rates.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Pentair, Inc. and Subsidiaries

1. Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include Pentair, Inc. and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated.

Fiscal Year

Pentair has adopted a standard “4-4-5 week” accounting quarter for reporting in 1999. The duration of each quarter is approximately 13 weeks per quarter with the first three quarters always ending on a Saturday. The Company’s fiscal year ends on December 31.

Cash Equivalents

The Company considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents.

Property, Plant and Equipment

Property, plant and equipment is stated at cost. Depreciation is computed using the straight-line method. Estimated useful lives are: land improvements - - 5 to 20 years, buildings - 5 to 50 years, and machinery and equipment - 3 to 15 years.

Insurance Subsidiary

The Company'sCompany’s wholly owned insurance subsidiary, , Penwald Insurance Company, insures Company general and product liability, product recall, workers'workers’ compensation, and auto liability risks.

Reserves for policy claims ($35,441,00028,885,000 with $22,885,000 noncurrent as of December 31, 1999 and $35,441,000 with $29,441,000 noncurrent as of December 31, 1998 and $43,305,000 with $32,313,000 noncurrent as of December 31, 1997)1998) are established based on actuarial projections of ultimate loss.

In order to maximize investment earnings from insurance reserves, Penwald now has a long-term receivable from Pentair (established in July, 1997) in lieu of its former marketable securities portfolio. The intercompany receivable is interest bearing and payable on demand and eliminated in consolidation. Prior to July 1997, the insurance subsidiary invested in marketable securities including debt and equity securities classified as available-for- saleavailable-for-sale in accordance with Statement of Financial Accounting Standards No. 115, "Accounting“Accounting for Certain Investments in Debt and Equity Securities." Debt and equity securities classified as available-for-sale were carried at fair value on the balance sheet with unrealized gains and losses reported in a component of shareholders'shareholders’ equity.

The debt and securities investments were treated as operating assets of the insurance subsidiary and the related earnings ($2,864,000 and $1,824,000 in 1997,and 1996, respectively)1997) were recorded as a reduction of the insurance component of cost of sales. The 1997 gain on sale of securities from the liquidation of the portfolio ($5,932,000) was recorded as other income and included as a reduction of selling, general and administrative costs.

Goodwill

The excess purchase price paid over the fair value of net assets of businesses acquired is amortized on a straight-line basis over periods ranging from 25 to 40 years. The amortization recorded for 1999, 1998, 1997,and 19961997 was $25,911,000, $15,255,000, $14,113,000, and $11,160,000,$14,113,000, respectively. Accumulated amortization was $61,311,000$83,775,000, and $44,658,000$61,311,000 at December 31, 19981999 and 1997,1998, respectively. The Company periodically reviews goodwill to assess recoverability. The Company evaluates the recoverability by measuring the unamortized balance of such goodwill against estimated undiscounted future cash flows. If events or changes in circumstances indicated that the carrying amount of such asset might not be recoverable, the asset would be adjusted to the present value of the estimated future cash flows. Based on evaluations performed, there waswere no adjustmentadjustments to the carrying value of goodwill during any of the three years ended December 31, 1998. 1999.

Long-Lived Assets

Pentair evaluates the carrying value of long-lived assets. When the carrying value exceeds the projected undiscounted cash flows from the assets, an impairment is recognized to reduce the carrying value to the fair market value. Losses on long-lived assets to be disposed of are determined in a similar manner, except that the fair market values are reduced for

30


the cost to sell. Based on evaluations performed, there waswere no adjustmentadjustments to the carrying value of such assets during any of the three years ended December 31, 1998. 1999, except as included in the 1999 restructuring charge. See Note 3.

Foreign Currency Translation

Translation gains or losses resulting from translating foreign currency financial statements are reported as a component of shareholders'shareholders’ equity. Foreign currency transaction gains and losses are included in earnings as incurred.

Revenue Recognition

Revenue from sales is generally recognized at the time the product is shipped.

Product Warranty Costs

Provision for estimated warranty costs is recorded at the time of sale and periodically adjusted to reflect actual experience.

Research and Development

Research and development expenditures are expensed as incurred. Development activities generally relate to creating new products, improving or creating variations of existing products, or modifying existing products to meet new applications.

Earnings per Common Share

Basic earnings per common share is computed by dividing net income, after deducting preferred stock dividends, by the weighted average common shares outstanding during the period.

Diluted earnings per common share is computed by dividing net income, after adjusting the tax benefits on deductible ESOP dividends, by the weighted average common shares outstanding plus the incremental shares that would have been outstanding upon the assumed exercise of dilutive stock options and upon the assumed conversion of each series of preferred stock. The tax benefits applicable to preferred dividends paid to ESOPs are recorded in the following ways. For allocated shares, they are credited to income tax expense and included in the earnings per share calculation. For unallocated shares, they are credited to retained earnings and excluded from the earnings per share calculation. See also Note 19.

Reclassifications

Certain reclassifications have been made to prior years'years’ financial statements to conform to the current year presentation.

2. Adoption of New Accounting Standards

In 1998, the Company adopted the following new accounting standard: Statement of Financial Accounting Standard (FAS) No. 132, "Employers'“Employers’ Disclosures about Pensions and Other Postretirement Benefits"Benefits”. FAS 132 revises and standardizes disclosures for pensions and other postretirement benefits. See Note 15.

In 1997, the Company adopted the following accounting standards: Statement of Financial Accounting Standard (FAS) No. 128, "Earnings“Earnings per Share"Share”, Statement of Financial Accounting Standard (FAS) No. 130 "Reporting“Reporting Comprehensive Income"Income”, and Statement of Financial Accounting Standard (FAS) No. 131 "Disclosures“Disclosures about Segments of an Enterprise and Related Information"Information”. The impact of these new standards on Pentair was immaterial.

Prior year financial statements have been restated accordingly.

3. Accounting Developments Special Restructuring Charge

In June 1998, the Financial Accounting Standards Board issued Statementfirst quarter of Financial Accounting Standard No. 133, "Accounting1999, the Company recorded a special restructuring charge of $38.0 million ($24.1 million after-tax or $.56 per share). As shown below, $12.8 million has been spent or charged through December 31, 1999. The remaining balance is classified within Accrued Liabilities and Other Expenses on the balance sheet.

The restructuring plan comprises consolidation of certain operations, overhead reductions, and outsourcing of specific product lines in each of the Company’s three business segments. Pentair anticipates a reduction of approximately 1,050 jobs, as detailed below, offset by approximately 350 new jobs at other Pentair facilities in connection with consolidation and rationalization. The restructuring plan does not contemplate the Company exiting any of its current lines of business;

31


the projects involved are designed to make the Company’s existing businesses more efficient.

The Professional Tools and Equipment segment is consolidating North American distribution operations and combining the headquarters of the two power tool businesses, Delta and Porter-Cable, in Jackson, Tennessee. In the service equipment businesses, products are being outsourced to offshore manufacturers or transferred to other North American facilities. The Jonesboro, Arkansas manufacturing operation of Lincoln Automotive will be closed. These actions will result in the termination of more than 600 employees. Restructuring charges for Derivative Instrumentsthis segment amounted to $16.8 million, $10 million of which is attributable to employee terminations, and Hedging Activities."the balance of which relates to asset write-downs and other exit costs. Management estimates the benefits under the restructuring plan will be approximately $16 million in 2000 and $15 million in 2001.

The Water and Fluid Technologies segment has reduced the workforce at its Lincoln Industrial business and is outsourcing some product manufacturing, resulting in headcount reductions of approximately 100 employees. Lincoln Industrial plans to eliminate approximately 50 percent of the manufacturing space at its U.S. manufacturing facilities. The charge for this segment was $4.5 million, approximately $1.2 million of which relates to terminated employees, and the balance of which is attributable to demolition and other exit costs. Management estimates the benefits under the restructuring plan will be approximately $2 million in 2000 and $2 million in 2001.

The Electrical and Electronic Enclosures segment reduced its workforce in Europe and adopted a plan to rationalize manufacturing at its North American facilities. These actions will result in the reduction of approximately 350 employees. This segment absorbed $16.7 million of the charge, largely related to employee terminations. Management estimates the benefits under the restructuring plan will be approximately $9 million in 2000 and $12 million in 2001.

The components of the restructuring charge and related reserve balances remaining at December 31, 1999 were (in millions):

Remaining Reserve$18.1$4.0$3.1$25.2




“Personnel Costs” consists of severance, medical plan continuation, pension cash-outs, and outplacement per company policy for the 1,050 employees planned to be terminated. As of December 31, 1999, approximately 400 employees have been terminated (or in Europe are working under statutory notice periods).

“Asset Disposals” consists of the write-down of the carrying value of the Delta headquarters building which is held for resale and the write-off of special-use manufacturing and support assets which will no longer be needed and which will be scrapped or abandoned. The real estate held for resale is expected to be disposed of by mid-2000. All of these assets are currently classified as property, plant and equipment. No charge has been taken with respect to the Jonesboro real estate since the Company believes it will be able to be sold for book value within a reasonable period.

“Exit Costs” consists of maintenance and security costs of surplus buildings until leases expire or demolition or disposal of certain buildings, including the Jonesboro building.

“Personnel Costs” and “Exit Costs” are cash costs and the “Asset Disposals” are primarily non-cash costs. Our currently anticipated schedule projects cash expenditures of $19 million in 2000 and $2 million in 2001. These requirements will be funded through cash from operations or borrowings under our existing credit facilities.

During 1999, restructuring benefits (largely personnel cost savings) of approximately $6 million were realized. Anticipated

32


benefits are projected to be $26 million in 2000 and $30 million in 2001. The major components of anticipated benefits are in reductions in labor costs and efficiencies in consolidating distribution and administrative functions.

The anticipated benefits noted above are net of the costs of adding 350 employees at other Pentair locations. The benefits do not, however, take into account one-time costs associated with these restructuring plans. The Company must adopt this standard no later than January 1,anticipates that the associated one-time costs will amount to approximately $6 million, one-quarter of which was incurred in 1999, with most of the balance to be incurred in the first quarter of 2000. The Company is reviewingThese costs are not included in the requirementsrestructuring charge, since they relate to asset relocations, start-up costs and training and recruiting of this standard, which are quite complex.

7. Financial Instruments

The Company utilizes various derivatives such as interest rate swap agreements, currency swap agreements, and interest rate cap agreements. The Company also utilizes commodity swap agreements from time to time. The Company uses these derivatives in a strategic manner to minimize interest rate and foreign currency risk. The instruments are not purchased as speculative investments. Derivatives used for hedging purposes must be designated as, and effective as, a hedge of an identified risk exposure at the inception of the contract. Accordingly, changes in the fair market value of the derivative contract must be highly correlated with the changes in the fair market value of the underlying hedged item both at the inception of the hedge and over the life of the hedge contract.

Foreign exchange contracts are accounted for as hedges to the extent they are designated as, and are effective as, hedges of firm or anticipated foreign currency commitments. Any foreign exchange contracts designated but no longer effective as a hedge are marked to market and the related gains and losses are recognized in earnings.

Interest rate contracts designated and effective as a hedge of underlying debt obligations are not marked-to-market, but cash flow from such contracts results in adjustments to interest expense recognized over the life of the underlying debt agreement. Gains and losses from terminated contracts are deferred and amortized over the remaining period of the original contract. Cash flows from such terminations are classified according to the underlying financial instrument the contract was designated to hedge. Open interest rate contracts are reviewed regularly to ensure that they remain effective as hedges of interest rate exposure.

The Company hedges its net investments in significant foreign subsidiaries by borrowing in those subsidiaries’ functional currencies. The Company has also entered into currency swap agreements, principally to Deutschemarks and Italian Lira, with major financial institutions to hedge firm foreign currency commitments. The notional amounts serve as a basis for the calculation of interest payments which are exchanged over the life of the swap transaction and are equal to the amount of foreign currency or dollar principal exchanged at maturity.

Gains and losses on contracts designated as hedges of net investments in foreign subsidiaries are recognized in shareholders’ equity as foreign currency translation adjustments. Gains and losses on contracts designated as hedges of identifiable foreign currency firm commitments are not recognized until the gains or losses of the related foreign currency transactions are recognized.

Interest Rate Risk Management The Company has entered into interest rate swap agreements with 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. Net payments or receipts under the agreements are recorded as adjustments to interest

The weighted average fair value of each option grantoptions granted is estimated on the date of grant using the Black-Scholes option-pricing model and represents the difference between the fair market value on the date of grant and the estimated market value on the exercise date. The model useswith the following weighted-average assumptions:

The expected life was determined separately for each of the Omnibus Stock Incentive Plan and the Outside Directors Nonqualified Stock Option Plan, due to differing exercise patterns.

The fair value for all options as a group are determined using the Black-Scholes model. The number of shares for which the options are granted in a year is multiplies by the fair value of each option to arrive at the total fair value of all options granted.

The total fair value is amortized to expense over the three-year option vesting period in determining the proforma impact of the alternative method of determining the compensation cost of the options.

Employees covered under the non-bargaining pension plans are eligible to participate upon the attainment of age 21 and the completion of one year of service; and benefits are based upon final average salary and years of service. All employees are fully vested in the plans after 5-7 years of service. The Company'sCompany’s funding policy is to make contributions as required by applicable regulations.

Other Benefits

The Company provides certain health care and life insurance benefits for retired employees. Employees become eligible for these benefits if they meet minimum age and service requirements and are eligible for pension benefits.

In 1999, Pentair acquired DeVilbiss Air Power Company. As part of that transaction, appropriate pension assets and liabilities for DeVilbiss Air Power Company employees were transferred into the Company’s pension plans.

In November 1997, Pentair divested the Federal Cartridge business. As part of that transaction, appropriate pension assets and liabilities for Federal Cartridge employees were transferred to the buyer’s pension fund. This pension asset transfer was not effected until 1998 following the necessary actuarial calculations; therefore this asset transfer did not match the fiscal period for the sale of Federal Cartridge.

At December 31, 1998,1999, for plans with assets less than PBO,Projected Benefit Obligation (PBO), the aggregate PBO is $52.0$45.2 million and the aggregate assets are $5.9$0.2 million. For plans with assets less than ABO,Accumulated Benefit Obligation (ABO), the aggregate ABO is $40.7$39.8 million and the aggregate assets are $0.1 million.zero. The majority of the under funding is related to German pension plans, which are not commonly funded.

Revenues are attributed to countries based on location of customer. Assets are based on the geographic location of the subsidiary and have been translated into US dollars.

In evaluating financial performance, management focuses on operating income as a segment'ssegment’s measure of profit or loss. Operating income is before interest expense, interest income and income taxes. Management uses a variety of balance sheet ratios to measure the business. The primary focus is on maximizing the return from each segment'ssegment’s assets, excluding cash and temporary investments. The accounting policies of the segments are the same as those described in the summary of significant accounting policies (Note 1). Most intersegment sales are component parts and are sold at cost plus an equitable division of manufacturing and marketing profits. The remaining intercompany sales are finished product and are sold based on current market pricing to third parties.

18. Disclosure of Risks and Uncertainties

Pentair, Inc. is engaged principally in the design, engineering, and manufacturing of various industrial products. The diversified businesses manufacture woodworking equipment, power tools, vehicle service equipment, pumps, water conditioning control valves, industrial lubrication systems and material dispensing equipment, and enclosures for electrical and electronic equipment.

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

The Company has retained certain obligations of discontinued and divested businesses. Based on evaluations by management and environmental professionals, amounts for currently estimable and probable risks or obligations have been accrued.

Although the individual subsidiaries deal with major customers throughout North America and Europe, Pentair as a whole has mitigated any significant impact or potential risk of concentration of customers or products, or in certain markets or geographic areas. This is due to the diversified nature of the Company and its product lines.

19. Earnings Per Share

In 1997, the Company adopted Statement of Financial Accounting Standards (FAS) No. 128, "Earnings per Share". Earnings per share amounts presented for 1996 have been restated for the adoption of FAS 128.Share”. The following table reflects the calculation of basic and diluted earnings per share.

      20. Accounting Developments
In June 1998, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standard (“SFAS”) No. 133, “Accounting for Derivative Instruments and Hedging Activities.” The FASB subsequently issued SFAS No. 137 delaying the effective date for one year, to fiscal years beginning after June 15, 2000. The Company must adopt this standard no later than January 1, 2001. The Company is reviewing the requirements of this standard, which are quite complex. Although the Company expects that this standard will not materially affect its financial position and results of operations, it has not yet determined the impact of this standard on its financial statements.
