DOCUMENTS INCORPORATED BY REFERENCE Portions of 1993 Annual Report to Stockholders Parts I, II and IV Portions of Definitive Proxy Statement for the Annual Meeting of Stockholders to be held on May 5, 1994 Part III /2 PART I Item 1. BUSINESS Ionics, Incorporated ("Ionics," the "Company," or the "Registrant") is a leading water purification company engaged worldwide in the supply of water and of water treatment equipment through the use of proprietary separations technologies and systems. Ionics' products and services are used by the Company or its customers to desalt brackish water and seawater, to purify and supply bottled water, to treat water in the home, to manufacture and supply water treatment chemicals and ultrapure water, to recycle and reclaim process water and wastewater, and to measure levels of water-borne contaminants and pollutants. The Company's customers include industrial companies, consumers, municipalities and utilities. The Company's business activities are divided into three segments: membranes and related equipment, water and chemical supply, and consumer water products, which in 1993 accounted for approximately 53%, 29% and 18% of revenues, respectively. Since 1985, the Company has pursued a strategy of expanding beyond its traditional focus of selling desalination plants and equipment by owning and operating its own equipment to produce and sell water and chemicals. Approximately 45% of the Company's 1993 revenues were derived from foreign sales or operations. Over forty years ago, the Company pioneered the development of the ion-exchange membrane and the electrodialysis process. Since that time, the Company has expanded its separations technology base to include the electrodialysis reversal (EDR), reverse osmosis (RO), ultrafiltration (UF) and microfiltration (MF) membrane processes, as well as related processes such as electrodeionization (EDI), ion exchange and carbon adsorption. With its acquisition of the business of Resources Conservation Company (RCC) at the end of 1993, the Company's separations technology base now includes thermal processes such as evaporation and crystallization. The Company believes that it is the world's leading manufacturer of ion- exchange membranes and of membrane-based systems for the desalination of water. The Company was incorporated in Massachusetts in 1948. The Company's principal executive offices are located at 65 Grove Street, Watertown, Massachusetts 02172. Financial Information About Business Segments The information contained in Note 14 of Notes to Consolidated Financial Statements contained in the Company's Annual Report to Stockholders for the year ended December 31, 1993 is incorporated herein by reference. Membranes and Related Equipment The Company's membranes and related equipment business segment, which /3 I-1 accounted for approximately 53% of revenues in 1993, currently encompasses the following products: electrodialysis reversal systems; reverse osmosis systems; microfiltration systems; non-membrane water and wastewater treatment equipment; other separations technology products; instruments for monitoring and on-line detection of pollution levels; fabricated products; and brine concentrators, evaporators and crystallizers utilizing thermal separations processes. EDR Systems The Company's AquamiteR desalination systems utilize Ionics' EDR process to treat brackish water and produce potable water for commercial, municipal, and a variety of industrial purposes. The Company has built and installed approximately 2,000 systems and plants utilizing its ED and EDR technology. Today, the Company sells, under the Aquamite name, a number of standardized versions of EDR equipment, which are designed for ease of installation and low maintenance and have production capacities ranging from 500 gallons to 1.5 million gallons per day. Multiple unit configurations are used for systems of larger capacities. Customers for water purification systems increasingly have requested the Company to supply complete turnkey plants. For such customers, Ionics provides basic Aquamite equipment, peripheral water treatment equipment, complete engineering services, process and equipment design, project engineering, commissioning, operator training and field service. RO Systems The Company manufactures seawater desalination plants as well as systems for the production of ultrapure water which utilize RO membrane technology. The Company owns and operates seawater desalination plants in Grand Canary, Spain, Santa Barbara, California, and at the Diablo Canyon Power Plant in California. See "Water and Chemical Supply." MF Systems Utilizing the Company's proprietary Aqua-PoreR microfiltration membranes, the Company's EnviromatR Integrated Membrane Filtration System removes toxic contaminants such as lead, nickel and other materials from industrial wastewaters and enables manufacturers to meet stringent regulations for effluent compliance. Non-Membrane Water and Wastewater Treatment Equipment Through its wholly owned Italian subsidiary, Ionics Italba, S.p.A., Ionics designs, engineers and constructs customized systems for wastewater and municipal water treatment. These include ion-exchange systems which provide purified water for power stations, chemical and petrochemical plants, metalworking and automobile factories, textile manufacture and a variety of other industrial applications. Other systems neutralize and /4 I-2 filter industrial wastewater, separate suspended solids and, in some cases, recover chemicals. Ionics Italba also provides custom municipal and packaged sewage treatment systems. Ionics Italba generally subcontracts the construction activities associated with its projects. Through its Resources Conservation Company (RCC) business unit, Ionics designs, engineers and constructs brine concentrators, evaporators and crystallizers which are used to clean, recover and recycle wastewater, particularly in zero liquid discharge industrial uses. RCC also developed, and holds an exclusive license for, a patented solvent extraction technology known as B.E.S.T. (Basic Extractive Sludge Technology), which separates contaminated sludges, sediments and soils into oil, water and solids, and has potential use for the cleanup of toxic organic materials at Superfund Sites. Other Separations Technology Products Using its separations technology, Ionics manufactures, markets or supplies products which are used in the recovery and recycling of selected components from process streams, the manufacture of commodity and specialty compounds and the purification of valuable fluids. The Company's ElectromatR system is used in the demineralization of cheese whey to produce a major component utilized extensively in infant formula products. A similar Ionics system is used to deacidify fruit juices for a manufacturer of canned fruit products. The Company's food product revenues have been derived from three sources: the design and construction of the system, the manufacture and sale of replacement membranes used in the system, and in certain applications a royalty (based on Ionics' U.S. patents) on the throughput of product. At the end of 1993, the Company obtained an additional source of food produce revenues by entering into an agreement with a major U.S. dairy cooperative to oversee whey processing activities at plants owned by the cooperative, for which the Company will receive a processing fee based on the production of demineralized whey. Other Ionics process systems include the ChemomatR system to generate organic acids and to recover, recycle, remove and separate metals and other components from industrial wastewaters, and the CloromatR system for the production of sodium hypochlorite and related chlor-alkali chemicals. Instruments for Monitoring and On-Line Detection of Pollution Levels The Company designs, manufactures and sells equipment to measure the quality of treated or untreated water. Its products, which are used by industrial and governmental customers to measure organic and toxic contaminants in water and chemical process streams, include process and laboratory instruments to measure total carbon, total organic carbon, chemical oxygen demand and total oxygen demand. The Company recently expanded the monitoring capabilities of its instruments with the introduction of analyzers to measure concentrations at the parts per billion level of dissolved metals such as copper, lead, iron, mercury, and arsenic and specific chemical analyzers for ammonia, phosphates, nitrates, /5 I-3 and chlorine. The process systems provide real-time measurement of the level of contaminants in active waste streams. Another product, the DigichemR, sold principally to the printed circuit board, pulp and paper, and chemical and petrochemical industries, functions as a "robot chemist" capable of performing automatically "wet chemistry" analyses traditionally done manually. Fabricated Products At its Bridgeville, Pennsylvania facility, the Company fabricates specially designed products for defense-related and industrial applications. The Company's experience and expertise in design, welding, machining and assembly to meet exceptionally fine tolerances have been utilized to fabricate products ranging from intricate small parts to very large 35-ton assemblies. Water and Chemical Supply The water and chemical supply business segment accounted in 1993 for approximately 29% of the Company's revenues. The Company's strategy is to sell, where appropriate, water and chemicals produced by its membrane-based equipment, rather than selling the equipment itself. The water and chemical supply business segment can be divided into three categories: sale of desalted water for municipal and industrial use; sale of ultrapure water for electronics and other industries; and sale of bleach and related chemicals. Sale of Desalted Water for Municipal and Industrial Use Ionics' position in water supply as a seller of purified or treated water has evolved from its traditional role as a supplier of water treatment equipment. In certain situations, opportunities are available for the Company to provide a complete service package involving financing, construction, operation and maintenance of water treatment facilities. Ionics, through its wholly owned subsidiary, Ionics Iberica, S.A., owns and operates a 5.5 million gallon per day capacity brackish water EDR facility and a 2.0 million gallon per day RO seawater facility on Grand Canary Island, Spain. Under long-term contracts, the Company is selling the desalted water from both facilities to the local water utility for distribution. The Company's wholly owned subsidiary, Ionics (Bermuda) Ltd., operates a 600,000 gallon per day EDR brackish water desalting plant on the island of Bermuda. This plant supplies fresh water under a long-term contract with Watlington Waterworks Ltd., a Bermuda corporation partially owned by Ionics. /6 I-4 The Company financed and constructed, and owns and operates, an RO desalination facility in Santa Barbara, California. The facility began operation in March 1992, has the capacity to produce 7,500 acre-feet per year (approximately 6.7 million gallons per day) of desalinated water, and is expandable to 10,000 acre-feet per year. Under the terms of the Company's contract with the City, the City can either purchase water from the Company or, under conditions in which the City deems it unnecessary to purchase water, pay the Company a "stand-by fee" during the contract's five-year term and, if the City elects to continue, a five-year extension term. The City has placed the facility on "stand-by" status because of the alleviation of the area's drought. At the end of the initial five-year term, the City will have the right to renew the contract for another five- year term, purchase the facility from the Company, or direct the Company to remove the facility (most of which is housed in trailers) from its site. In the event the City purchases the facility, the City must reimburse the Company for all costs not previously recovered from operations, plus a factor to cover general and administrative expenses and profit. Sale of Ultrapure Water for Electronics and Other Industries In industries from biotechnology and chemical processing to pharmaceuticals and semiconductors, ultrapure water (water in which the impurities have been reduced to concentrations of less than several parts per billion) is critical to product quality and yield. In the electric power industry, ultrapure boiler feedwater minimizes corrosion, inefficiency and downtime in steam boilers and turbines. Depending on the composition and quantity of the impurities to be removed or treated, any one of several membrane separations methods can be utilized to provide ultrapure water to the customer. Ionics has pioneered in the application of three membrane technologies (EDR, RO and UF) combined together in a mobile system called the "triple membrane" trailer, which the Company believes to be the most advanced technology used in the commercial processing of ultrapure water. Ionics provides ultrapure water services through the sale of ultrapure water in 6,000 gallon tank trucks and the production and sale of ultrapure water from trailer-mounted units at the customer sites. In 1992, Ionics announced the commercial implementation of its new electrodeionization (EDI) technology in the production of ultrapure water. EDI is a continuous, electrically driven, membrane-based water purification process which produces ultrapure water without the use of the strong chemical regenerants, such as sulfuric acid and caustic soda, which are commonly required. In 1993, trailers utilizing EDI technology were in service at sites in Florida, Arkansas and Mississippi. In March 1992, the Company began a ten-year, $20 million contract to provide process water and ultrapure boiler feedwater to Pacific Gas and Electric's Diablo Canyon Power Plant on the central coast of California. In 1993, ten-year ultrapure water contracts were obtained from Florida Power and Light for its Turkey Point fossil fuel power plant near Florida City, and for the Seabrook Nuclear Station in Seabrook, New Hampshire. /7 I-5 The Company serves the ultrapure water market from its headquarters facilities in Watertown, Massachusetts, through the Ionics Pure Solutions Division in Phoenix, Arizona, and through the following subsidiaries: Ionics Ultrapure Water Corporation, Campbell, California; Ionics (U.K.) Limited, London, England; Ionics Italba, S.p.A., Milan, Italy; and Eau et Industrie, Paris, France. Sale of Bleach and Related Chemicals In the chemical supply area, the Company uses its CloromatR technology to produce sodium hypochlorite (household bleach) and related chlor-alkali chemicals in a membrane-based process that principally relies on water and salt as raw materials. The Company's wholly owned Australian subsidiary, Elite Chemicals Pty. Ltd., utilizes Cloromat systems to produce sodium hypochlorite on-site in Brisbane, for sale to the bulk market. In 1993, the Company's wholly owned English subsidiary, Ionics (U.K.) Limited, commenced bulk bleach sales at a new Cloromat facility in Bridgwater, England. A large portion of the facility's output is being sold to Courtaulds Films (Holdings) Limited for use in cellophane manufacture, and the balance is being sold to the regional market. In the United States, the Company's Elite Chemicals New England division operates a Cloromat facility in Springfield, Massachusetts which produces and distributes bleach-based products for the consumer market, primarily one-gallon bleach products under private label or under the Company's own "Elite" brand. In September 1993, the Company contracted to purchase a larger manufacturing facility, located in Ludlow, Massachusetts. The Company intends to pursue a strategy of utilizing Cloromat equipment and technology at Company-owned facilities to produce high quality bleach and other chlor-alkali products at selected regional sites in the United States and overseas. Consumer Water Products Ionics' consumer water products business segment accounted for approximately 18% of the Company's revenues in 1993. The Company's consumer water products include bottled water, over and under-the-sink point-of-use devices, and point-of-entry systems for treating the entire home water supply. Aqua CoolR Pure Bottled Water Ionics entered the bottled water business in 1984. The Company's strategy is to utilize its proprietary desalination and purification technology to create a brand of drinking water, named Aqua Cool Pure Bottled Water, which can be reproduced with uniform consistency and high quality at numerous locations around the world. Distribution operations have been established to serve the areas in and around London and Manchester, England; Boston, Washington and Baltimore in the United States; and, through joint ventures, in Bahrain, Kuwait and Saudi Arabia. The Company's business focuses on the sale of Aqua Cool in five-gallon bottles to a variety of customers including banks, office buildings, commercial /8 I-6 establishments, hospitals and private homes. The Company also manufactures coolers in a wide variety of colors which offer options for hot, cold and room temperature water. In 1989, the Company entered into agreements with Aqua Cool Enterprises, Inc. (ACE), a newly formed, independently owned corporation, which established ACE as a marketer and distributor of Aqua Cool in 10 eastern states and the District of Columbia, and provided for Ionics' supply to ACE of products, management services and operational support. In May 1993, the Company loaned $8.25 million to ACE which was used by ACE to redeem debt and preferred stock of ACE held by Westinghouse Credit Corporation. In June 1993, the Company's loan was converted into preferred stock, and as a result of these transactions, the Company now consolidates the operating results of ACE. ACE operates eight distribution centers in Massachusetts, Connecticut, New York, New Jersey, Pennsylvania and Virginia, which augment the Company's distribution network. At the end of 1993, there were a total of 17 Aqua Cool distribution centers in the United States and overseas, supplied with Aqua Cool by five regional water purification and bottling facilities which are owned and operated by the Company. Construction was being completed of a new, larger bottling facility located outside Washington, D.C., and plans were being prepared to construct a third U.S. bottling facility in northern New Jersey. In January 1994, the Company announced plans to begin distribution of Aqua Cool in the Cincinnati, Ohio area. Aqua Cool's focus has been in particular to obtain large commercial or governmental supply contracts for five-gallon delivery, such as the estimated $2 million, two-year contract awarded in 1993 by the City of New York Department of General Services. Point-of-Use Devices The Company participates in the "point-of-use" market for over and under-the-sink water purifiers through the manufacture and sale of HYgeneR, a proprietary, EPA-registered, silver-impregnated activated carbon filtering media, and through the sale of reverse osmosis and activated carbon-based filtering devices. The Company incorporates HYgene, which is designed to prevent bacterial build-up while providing the capability of removing undesirable tastes and odors from the water supply, into its own bacteriostatic water conditioners and also sells HYgene to manufacturers of household point-of-use water filters. In 1993, a substantial decline in HYgene sales to other manufacturers continued as a result of lack of business from the largest of the Company's HYgene customers. Point-of-Entry Systems Ionics' point-of-entry water products include ion-exchange water conditioners to "soften" hard water, and chemicals and media for filtration and treatment. The Company sells its products, under the General Ionics brand, through both independent distributorships and wholly owned sales and service dealerships. For water conditioners sold by the latter, the Company provides customer financing. /9 I-7 Raw Materials and Sources of Supply All raw materials essential to the business of the Company can normally be obtained from more than one source. In those few instances where raw materials are being supplied by only one source, the current supplier has given the Company a lead time for cancellation, which the Company believes is sufficient to enable it to obtain other suppliers. In addition, the Company maintains inventories of single source items which it believes are adequate under the circumstances. The Company produces the membranes required for its equipment and systems that use the ED, EDR, MF, and EDI processes. Membranes used for the RO and UF processes are purchased from outside suppliers, and are normally available from multiple sources. Patents and Trademarks The Company believes that its products, know-how, servicing network and marketing skills are more significant to its business than trademark or patent protection of its technology. Nevertheless, the Company has a policy of applying for patents both in the United States and abroad on inventions made in the course of its research and development work for which a commercial use is considered likely. The Company owns numerous United States and foreign patents and trademarks and has issued licenses thereunder, and currently has additional pending patent applications. Of the 107 active U.S. patents held by the Company, a substantial portion involves membranes, membrane technology and related separations processes such as electrodialysis and electrodialysis reversal, reverse osmosis, ultrafiltration and electrodeionization. The Company believes that none of its individual patents or groups of related patents, nor any of its trademarks, is of sufficient importance for its termination or abandonment, or cancellation of licenses extending rights thereunder, to have a material adverse effect on the Company. Seasonality The activities of the Company's businesses are not of a seasonal nature, except that bottled water sales and bleach products for swimming pool use tend to increase during the summer months. Also, the Company's Elite Chemicals New England Facility produces windshield wash solution, for which sales levels increase in the winter months. Customers The nature of the Company's business is such that it frequently has in progress large contracts with one or more customers for specific projects; however, there is no one customer whose purchases account for 10% or more of the Company's consolidated revenues and whose loss would have a material adverse effect on the Company and its subsidiaries taken as a whole. /10 I-8 Backlog The Company's backlog of firm orders was $129,271,000 at December 31, 1993 and $125,506,000 at December 31, 1992. In the case of multi-year contracts entered into through June 30, 1991, the Company initially included in reported backlog only the revenues expected from the first four years of the contract. For multi-year contracts entered into after that date, the Company has initially included in reported backlog the revenues associated with the first five years of the contract. Also, the Company now includes in backlog up to one year of revenues relating to multi-year contracts which are not otherwise included in backlog. Ionics expects to fill approximately 75% of its December 31, 1993 backlog during 1994. The Company does not believe that there are any seasonal aspects to these backlog figures. Government Contracts The Company does not believe that any of its sales under U.S. Government contracts or subcontracts during 1993 are subject to renegotiation. The Company has not had adjustments to its negotiated contract prices, nor are any proceedings pending for such adjustments. Research and Development Since the development of the ion exchange membrane and the EDR process, Ionics has continued its commitment to research and development directed toward products for use in water purification, processing and measurement, and separations technology. The Company's research and development expenses were approximately $3,678,000 in 1993, $3,084,000 in 1992, and $2,886,000 in 1991. Competition The Company experiences competition from a variety of sources with respect to virtually all of its products, systems and services, although the Company knows of no single entity that competes with it across the full range of its products and services. Competition in the markets served by the Company is based on a number of factors, which may include price, technology, applications experience, know-how, availability of financing, reputation, product warranties, reliability, service and distribution. With respect to the Company's membrane and related equipment business segment, there are a number of companies, including several sizable chemical companies, that manufacture membranes, but not equipment. There are numerous smaller companies, primarily fabricators, that build water treatment and desalination equipment, but which generally do not have their own proprietary membrane technology. A limited number of companies manufacture both membranes and equipment. The Company has numerous competitors in its conventional water treatment, instruments and fabricated products business lines. /11 I-9 In 1992, the International Desalination Association released a report providing data regarding the manufacturers of desalination equipment. According to the report, which covered land-based water desalination plants delivered or under construction as of December 1991, with a capacity to produce 100 cubic meters (approximately 25,000 gallons) or more of fresh water daily, Ionics ranked first in terms of the cumulative number of such plants sold, having sold 1,127 plants of such capacity, more than the next three manufacturers combined. When compared only to manufacturers of membrane-type desalination equipment, Ionics ranked first in both number of units sold and the total capacity of units sold. With respect to the water and chemical supply business segment, the Company competes with regional suppliers of ultrapure water services, and with other manufacturers of membrane-related equipment. In the chemical supply activity, the Company competes with manufacturers and distributors of bleach and water treatment chemicals. With respect to the Company's consumer water products business segment, there are numerous bottled water companies which compete with the Company, including several which are much larger than the Company. Most of the Company's competitors in point-of-entry and point-of-use products for the home are small assemblers, serving local or regional markets. However, there are also several large companies competing nationally in these markets. In the case of its silver-impregnated activated carbon product lines, the Company knows of two competitors with which it competes on a national basis. The Company is unable to state with certainty its relative market position in all aspects of its business. Many of its competitors have financial and other resources greater than those of the Company. Environmental Matters Continued compliance by the Company or by its subsidiaries with federal, state and local provisions regulating the discharge of materials into the environment or otherwise relating to the protection of the environment is expected to have no material effect upon capital expenditures, earnings or the competitive position of the Company or any of its subsidiaries. The Company is one of more than 200 potentially responsible parties (PRPs) in connection with the Silresim Superfund Site in Lowell, Massachusetts. Under the Comprehensive Environmental Response Compensation and Liability Act (CERCLA or Superfund), the U.S. Environmental Protection Agency (EPA) has the authority to undertake remedial action at a Superfund site and hold responsible parties liable, on a joint and several basis and without regard to fault or negligence for costs incurred. Under the terms of a 1992 Settlement Agreement among the PRPs, EPA and the Commonwealth of Massachusetts, Ionics paid $381,000 as a settlement amount to the site settlement trust fund, representing the Company's approximately 1% volumetric contribution of wastes to the site. This fund will be used by /12 I-10 the EPA to clean up the Silresim Site. The amount paid by Ionics had been fully reserved at December 31, 1991, and the payment had no material adverse impact on the Company. Because the pollution problems at the site have been extensively studied and because the funds collected from the settling PRPs by the site settlement trust fund substantially exceeds the EPA's own estimate of remediation costs, the Company believes that it is highly unlikely that it will incur any further monetary obligations with respect to this site, other than site access costs that will be incurred by the EPA in connection with its remediation activities. The Company's share of these site access costs is expected to be $30,000 to $40,000 over the next several years. The Company was notified in June 1992 that it is a PRP at another Superfund site, Solvent Recovery Service of New England, in Southington, Connecticut (the "SRS Site"). The EPA has not yet completed its remedial investigation or issued a record of decision specifying estimated clean-up costs, and therefore it is too early to determine what the Company's liability might be with respect to the SRS Site. However, based upon the very large number of PRPs identified with respect to the SRS Site (over 1,000), the Company's small volumetric ranking in comparison to the total volume of wastes brought to the SRS Site (just under 0.5%), and the identities of the larger generators, which include many substantial companies, the Company believes that its liability in this matter will not have a material effect on the Company or its financial results. The Company's intention is to participate in the settlement agreement finally structured for the Site, so long as such agreement is fair to the parties. The Company has never had a product liability claim grounded in environmental liability, and believes that the nature of its products and business makes such a claim unlikely. Employees The Company and its consolidated subsidiaries employ approximately 1,300 full-time persons, none of whom are represented by unions except for the employees of the Company's Australian subsidiary and certain employees of the Company's Spanish subsidiary. The Company considers its relations with its employees to be good. Foreign Operations The Company's sales to customers in foreign countries primarily involve desalination systems, water and wastewater treatment systems and related products and services. The Company seeks to minimize financial risks relating to its international operations. Wherever possible, the Company obtains letters of credit or similar payment assurances denominated in dollars. If dollar payments cannot be secured, the Company, where appropriate, enters into foreign currency hedging transactions. The Company also uses foreign sources for equipment parts and may borrow funds in local (foreign) currency to offset the asset risk of foreign currency devaluation. Net foreign currency transaction gains included in income before taxes totalled $157,000 in 1993, $587,000 in 1992, and $180,000 in 1991. /13 I-11 Ionics engages in certain foreign operations both directly and through the following wholly owned subsidiaries: Ionics (Bermuda) Ltd.; Ionics Iberica, S.A.; Ionics (U.K.) Limited; Ionics Italba, S.p.A.; Ionics Nederland N.V.; Global Water Services, S.A.; Elite Chemicals Pty. Ltd.; Eau et Industrie; Resources Conservation Co. International; and Ionics Foreign Sales Corporation Limited. The Company engages in various foreign operations through investments in affiliated companies and joint venture relationships. The activities include the production, sale and distribution of bottled water through a 40% owned affiliate in Bahrain, a 40% owned affiliate in Saudi Arabia and a 49% owned affiliate in Kuwait. In addition, the Company has a 23% ownership interest in Watlington Waterworks Ltd. in Bermuda. Watlington collects, treats and distributes water throughout Bermuda for both potable and non-potable uses. The Company also has a 50% ownership interest in Yuasa-Ionics Co., Ltd., Tokyo, Japan, which among its other activities serves as a distributor of certain of the Company's products in Japan. Further geographical and financial information concerning the Company's foreign operations appears in Notes 1, 5, 8, 12, and 14 to the Company's Consolidated Financial Statements included as part of the Company's 1993 Annual Report to the Stockholders, which Notes are incorporated herein by reference. Financial Information About Foreign and Domestic Operations and Export Sales The information contained in Note 14 of Notes to Consolidated Financial Statements contained in the Company's Annual Report to Stockholders for the year ended December 31, 1993 is incorporated herein by reference. Item 2. PROPERTIES The Company owns or leases and occupies various manufacturing and office facilities in the United States and abroad. The principal facilities owned by the Company include two buildings in Watertown, Massachusetts housing the executive offices, laboratories and manufacturing and assembly operations; and facilities in Bridgeville, Pennsylvania; Phoenix, Arizona; Lorton, Virginia; Elkridge, Maryland; and Milan, Italy, for various operations relating to the design and manufacture of water purification and treatment equipment or water-related services. The two buildings in Watertown, Massachusetts which are owned by the Company and together contain approximately 250,000 square feet, are the subject of a mortgage securing the Company's guaranty with respect to industrial revenue bond financing of such facilities. The industrial revenue bond indebtedness will be discharged in 1994. /14 I-12 The other major facility owned by the Company is its Bridgeville, Pennsylvania facility, consisting of two buildings containing approximately 77,000 square feet and housing manufacturing operations for home water conditioners and stainless steel fabrication. The Company considers the business facilities that it utilizes to be adequate for the uses to which they are being put. Item 3. LEGAL PROCEEDINGS The Company is from time to time involved in litigation in the normal course of its business. At the present, the Company believes that there is no pending or threatened litigation the result of which would have a material adverse effect on the Company's earnings or financial position. See "BUSINESS - Environmental Matters." Item 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS No matters were submitted to a vote of security holders during the fourth quarter of the fiscal year covered by this report. /15 I-13 PART II Item 5.
