EXHIBIT 13 IONICS, INCORPORATED ANNUAL REPORT TO STOCKHOLDERS OF IONICS, INCORPORATED FOR THE FISCAL YEAR ENDED DECEMBER 31, 1993 (Only pages 17 through 32 and the inside back cover constitute an Exhibit to Form 10-K) /48 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Results of Operations In 1993, Ionics continued to improve its financial performance with a 13% growth in revenues and a 6% improvement in earnings per share. The profit improvement was driven primarily by the continued success of "own and operate" and service-based activities relating to the Water and Chemical Supply and Consumer Water Products business segments which combined to produce an improvement over 1992 in earnings before interest and taxes of 42%. This improvement more than offset a decline in the profitability of the Membranes and Related Equipment segment which was caused primarily by a slowdown in bookings and the acceptance and execution of orders at lower than normal margins. Total revenues were $175.3 million in 1993, compared with $155.2 million in the prior year. Revenues increased for all business segments with the largest growth in the Membranes and Related Equipment segment. Revenue growth in this segment was due to sales of ultrapure water systems, particularly to the semiconductor industry. A portion of the increase in 1993 revenues was attributable to the acquisition of the French subsidiary, Eau et Industrie, in December 1992, and Resources Conservation Company (RCC) in December 1993. Revenues from the Water and Chemical Supply business segment increased as large Company-owned plants, which commenced operations in the first quarter of 1992, operated for the entire period in 1993, and as domestic chemicals sales grew. Consumer Water Products revenues increased with the further development of the bottled water business and the consolidation of Aqua Cool Enterprises, Inc. (ACE), our domestic distributor, as of May 26, 1993. The increases in domestic equipment revenues, the expansion of the domestic chemical business, and the additions of ACE and RCC were responsible for the 21% growth in the U.S. geographic segment. Total revenues were $155.2 million in 1992, compared with $138.1 million in the prior year. The primary reason for the growth in 1992 over 1991 was the Company's increased investment in own and operate facilities, including those brought on line for the City of Santa Barbara and for the Diablo Canyon Power Plant of Pacific Gas and Electric. These facilities were also primarily responsible for the 48% growth in revenues of the Water and Chemical Supply business segment and the 20% growth in revenues of the U.S. geographic segment. The Membranes and Related Equipment segment realized a 6% sales increase in 1992 primarily due to sales of membrane systems for water and food processing applications. The Consumer Water Products segment's 1992 revenues declined 9% from 1991. This decline was largely caused by reduced sales of our HYgeneR silver-impregnated activated carbon filtering media to our largest HYgene customer due to depressed economic conditions. /49 Cost of sales as a percentage of revenues were 66.8%, 64.4%, and 65.4% in 1993, 1992 and 1991, respectively. Cost of sales as a percentage of revenues increased for the Membranes and Related Equipment segment while it held steady or declined for the Water and Chemical Supply and the Consumer Water Products segments, respectively. The increase in the Membranes and Related Equipment segment reflected greater than anticipated costs on several sizable capital equipment sales. The Consumer Water Products segment showed an improvement in the cost of sales percentage primarily due to a steady decline in the Company's unit costs to manufacture and distribute bottled water and coolers resulting from significant increases in volume, route density and operating efficiencies. The improvement in 1992 compared to 1991 was due primarily to reduced costs as a percentage of sales for membrane-based equipment and bottled water products. Water and Chemical Supply costs as a percentage of sales increased partially because of start-up costs and initial excess capacity in connection with the Company's expansion of its Elite Chemicals New England plant, and because nearly all of the costs associated with the Santa Barbara desalination plant are classified as cost of product, resulting in superior operating margins but below average gross margins. Operating expenses as a percentage of revenues were 23.5% in 1993, down from 26.1% in 1992 and 27.2% in 1991. The improvement in 1993 reflected the absorption of relatively fixed operating expenses by increased sales volume, with further reductions achieved through expense controls. The decrease in 1992 compared to 1991 reflected the low operating expenses associated with large own and operate facilities. Interest income in 1993 was $1.8 million compared to $2.1 million in 1992 and $1.5 million in 1991. The decrease in 1993 was due to lower average interest rates combined with reduced investments as a result of the 1993 purchase of ACE's preferred stock, the 1992 acquisitions, and additions to property, plant and equipment. The increase in 1992 compared to 1991 reflected higher average invested balances due to the remaining proceeds of the Company's public offerings of common stock in 1992 and 1991. The Company had virtually no interest expense in either 1993 or 1992 after interest expense of $1.4 million in 1991. This decrease primarily resulted from the repayment of debt with public offering proceeds and cash from operations. /50 The Company's effective tax rate was 30% in 1993, 29% in 1992 and 28% in 1991. The increase in the effective tax rate for both 1993 and 1992 was largely due to changes in the mix of earnings and effective tax rates among the different jurisdictions in which the Company operates, as well as a proportionately lower benefit from the Company's foreign sales corporation. The increase in 1992 was partially offset by a benefit from tax- exempt interest and a lower state tax rate due to proportionately lower domestic income. Net income increased 7.7% to $13.8 million in 1993 compared to $12.8 million in 1992. Net income in 1992 was 54.9% higher than 1991 net income of $8.3 million. Net income as a percentage of revenues was 7.9% in 1993 compared to 8.3% in 1992 and 6.0% in 1991. The Company adopted Financial Accounting Standards Board (FASB) Statement No. 109 " Accounting for Income Taxes" for the year 1993, with no material effect on its financial statements. LEGAL PROCEEDINGS The Company has been named as one of many potentially responsible parties (PRPs) in connection with two Superfund sites. During 1992, the Company paid $381,000 to the settlement trust fund for the Silresim Site in Lowell, Massachusetts. The Company was also notified during 1992 that it is one of more than 1,000 PRPs at a Superfund site in Southington, Connecticut. The Company's volumetric share at this site is just under 0.5%, and a remediation plan has not yet been adopted. The Company's volumetric contribution at these sites is low and there are many PRPs that are larger, financially sound corporations with higher volumetric levels. The Company accrues for estimated expenses as facts become known during these proceedings. Based upon facts presently known, management believes that the Company's liability in connection with these sites will not have a material adverse impact on its results of operations or financial condition. /51 FINANCIAL CONDITION At December 31, 1993, the Company had total assets of $249.6 million compared to total assets of $224.6 million at December 31, 1992 and $178.0 million at December 31, 1991. The major components of the increase in 1993 related to: (1) the consolidation of ACE in May 1993 and the acquisition of RCC in December 1993, and (2) expenditures for property, plant and equipment primarily relating to expansions of the Company's bleach production and distribution operations; bottled water operations; and triple-membrane trailers for the production of ultrapure water. The major components of the 1992 increase were: property, plant and equipment, due to expenditures for the California projects for the City of Santa Barbara and the Diablo Canyon Power Plant; triple membrane ultrapure water trailers; and the expansion of the Company's bleach business. In addition, cash and short-term investments increased due to the Company's February 1992 public offering of common stock. Working capital in 1993 decreased by $14.4 million and the Company's current ratio decreased to 2.4 in 1993 from 3.6 in 1992. Capital expenditures totaled $14.7 million, $24.7 million, and $34.9 million in 1993, 1992 and 1991, respectively. Cash paid for the 1993 purchase of ACE's preferred stock and 1992 acquisitions, net of cash acquired, was $8.0 million and $2.4 million, respectively. Funds for these expenditures were provided in 1993 through cash from operations and the sale of short-term investments and in 1992 through the sale of common stock and cash from operations. Net cash generated by operating activities decreased by $2.3 million in 1993 with higher net income and depreciation offset by increases in operating assets, primarily in accounts receivable, and decreases in liabilities primarily in accounts payable and accrued expenses, excluding those obtained through the consolidation of ACE and acquisition of RCC. Net cash used by investing activities decreased by $52.2 million in 1993 as compared to 1992. During 1993, cash used for investments in property, plant and equipment and for the purchase of ACE's preferred stock was funded primarily by the sale of short- term investments and partially by cash provided by operations. In 1992, purchases of short-term investments were funded primarily by the sale of common stock and partially by cash provided by operations. In 1993, net cash provided by financing activities decreased by $47.7 million as no public offering of common stock occurred in 1993. During 1992, cash of $54.0 million was provided from the sale of common stock. Net payments of debt decreased to $0.9 million in 1993 compared to $7.4 million in 1992. /52 Significant expenditures in 1994 will include: payment for the purchase of RCC; capital for ultrapure water trailers; expansion of the bottled water and bleach businesses; and improvements to manufacturing equipment. The Company maintains several lines of credit, including unused domestic lines totaling $35 million, which are available to meet working capital needs. In addition, the Company has several facilities to accommodate its foreign trade and exchange requirements. The Company believes that its cash and short-term investments of $30.1 million at the beginning of 1994, cash from operations, lines of credit and foreign exchange facilities are adequate to meet its currently anticipated needs. Inflationary increases in material and labor costs remained moderate during the last three years , and to the extent permitted by the competitive environment, the Company has raised prices to cover those inflationary increases. /53 Consolidated Statements of Operations Ionics, Incorporated For the years ended December 31 Dollars in thousands, except per share amounts 1993 1992 1991 Net revenue : Membranes and related equipment $ 92,352 $ 81,019 $ 76,267 Water and chemical supply 51,513 46,698 31,491 Consumer water products 31,408 27,523 30,362 175,273 155,240 138,120 Costs and expenses: Cost of membranes and related equipment 65,890 52,352 51,610 Cost of water and chemical supply 36,035 32,594 21,312 Cost of consumer water products 15,078 14,985 17,387 Research and development 3,678 3,084 2,886 Selling, general and administrative 37,432 37,409 34,743 158,113 140,424 127,938 Income from operations 17,160 14,816 10,182 Interest income 1,789 2,092 1,491 Interest expense - (5) (1,436) Equity income 775 1,281 1,412 Income before income taxes and minority interest 19,724 18,184 11,649 Provision for income taxes 5,917 5,273 3,262 Income before minority interest 13,807 12,911 8,387 Minority interest's share of income - (91) (109) Net income $ 13,807 $ 12,820 $ 8,278 Earnings per share $ 1.96 $ 1.85 $ 1.45 Shares used in earnings per share calculations 7,060,000 6,919,000 5,703,000 The accompanying notes are an integral part of these financial statements. /54 Consolidated Balance Sheets Ionics, Incorporated December 31 Dollars in thousands 1993 1992 Assets Current assets: Cash and cash equivalents $ 21,534 $ 13,535 Short-term investments 8,603 28,281 Notes receivable, current 2,505 3,195 Accounts receivable 57,214 43,640 Receivables from affiliated companies 2,944 4,096 Inventories 13,926 12,314 Other current assets 3,231 3,696 Total current assets 109,957 108,757 Notes receivable, long-term 4,919 10,156 Investments in affiliated companies 4,989 4,279 Property, plant and equipment, net 100,445 97,801 Other assets 29,252 3,597 Total assets $249,562 $224,590 Liabilities and Stockholders' Equity Current liabilities: Notes payable and current portion of long-term debt $ 326 $ 975 Accounts payable 12,496 12,272 Other current liabilities 32,332 16,060 Taxes on income 928 1,192 Total current liabilities 46,082 30,499 Long-term debt and notes payable 109 439 Deferred income taxes 2,699 2,777 Other liabilities 591 535 Commitments - - Stock holders' equity: Common stock, par value $1, authorized shares: 30,000,000 in 1993 and 1992;

SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The consolidated financial statements include the accounts of the Company, its wholly and majority-owned subsidiaries and Aqua Cool Enterprises, Inc., a controlled affiliate. All significant intercompany accounts and transactions have been eliminated. Investments in affiliated companies, representing non-majority ownership interests, are accounted for under the equity method. Revenue Recognition Product revenues are recorded upon shipment, and service revenues are recorded as the services are performed. Interest revenues on consumer water equipment loans are recognized over the life of the loans. Most equipment leases to customers are accounted for as operating leases wherein rental revenues are recognized over the life of the lease and the cost of the equipment is depreciated over its useful life. Some leases are accounted for as sales-type leases wherein the present value of the lease revenues and costs are recognized at the time of shipment of the product. Revenues from large contracts are recognized using the percentage completion method of accounting in the proportion that costs incurred bear to total estimated costs at completion. Losses, if any, are provided for in the period in which the loss is determined. Interest earned on notes receivable, totaling $1,277,000, $1,643,000 and $1,309,000 in 1993, 1992 and 1991, respectively, is included in revenues. Cash Equivalents Short-term investments with a maturity of 90 days or less from date of acquisition a reclassified as cash equivalents. Inventories Inventories are carried at the lower of cost or market, principally on the first-in, first-out basis. The Company had no deferred production costs which exceeded the aggregate estimated cost of long-term sales contracts. /58 Property, Plant and Equipment Property, plant and equipment is recorded at cost. When an asset is retired or sold, any resulting gain or loss is included in the results of operations. Interest capitalized as property, plant and equipment a mounted to $177,000, $709,000 and $703,000 in 1993, 1992 and 1991, respectively. Depreciation is computed on a straight-line basis over the expected lives of the assets, as follows: Classification Depreciation Lives Buildings and improvements 10-40 years Machinery and equipment, including water supply equipment 3-25 years Other 3-12 years The Company's policy is to depreciate desalination plants, other than leased equipment, over the shorter of their useful lives or the term of the corresponding water supply contracts. Goodwill Goodwill is included in other assets and represents the unamortized difference between acquisition cost and the fair value of net assets acquired in the purchase of various entities. Goodwill is amortized on a straight-line basis for up to 40 years. Foreign Exchange Assets and liabilities of foreign affiliates and subsidiaries are translated at year-end exchange rates, and the related statements of operations are translated at average exchange rates for the year. Translation gains and losses are accumulated net of income tax as a separate component of stockholdersU equity. Some transactions of the Company and its subsidiaries are made in currencies different from their own. Gains and losses from these transactions are included in income as they occur. Net foreign currency transaction gains included in income before taxes totaled $157,000, $587,000 and $180,000 for 1993, 1992 and 1991, respectively. Income Taxes Income tax expense is based on pretax financial accounting income. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax basis of assets and liabilities and their reported amounts. Earnings per Share Earnings per share is computed based on the weighted average number of common and common equivalent shares outstanding. Common equivalent shares result from the assumed exercise of dilutive stock options. Fully diluted earnings per share is substantially the same as earnings per share. /59 NOTE 2.

The Company's equity in the 1993 total revenues of these affiliates was $9,094,000. /61 Summarized data for foreign affiliates follows: Dollars in thousands 1993 1992 1991 Current assets $ 9,056 $ 8,622 $ 7,773 Property and equipment, net 8,169 7,848 5,262 Current liabilities 7,069 7,505 4,479 Long-term debt 424 584 652 Revenues 15,288 14,724 13,387 Gross profit 6,701 6,929 6,312 Net income 1,364 2,076 1,981 NOTE 6. CONTINGENT LIABILITIES The Company is from time to time involved in litigation in the normal course of its business. None of these litigation matters is believed to be material to the financial position or business of the Company. Under the terms of a 1992 Settlement Agreement among the potentially responsible parties (PRPs), the Environmental Protection Agency (EPA) and the Commonwealth of Massachusetts, the Company paid $381,000 as a settlement amount to the Silresim Superfund Site settlement trust fund, representing the Company's approximately 1% volumetric contribution of wastes to the site. This fund, which contains in excess of $40 million, will be used by the EPA to clean up the Silresim Site in Lowell, Massachusetts. The amount paid by the Company 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 exceed the EPA's own estimate of remediation costs, the Company believes that it is 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 (over 1,000), the Company's small volumetric ranking in comparison to the total volume of wastes (less than 0.5%) and the identities of the larger PRPs, 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 position. /62 NOTE 7.

Maturities of long-term debt and notes payable for the five years ending December 31, 1994 to 1998 are approximately $173,000, $22,000, $19,000, $8,000 and $7,000, respectively. The Company has domestic credit arrangements with various banks under which it can borrow up to an aggregate of approximately $35 million, at the prime rate or the London Interbank Offered Rate plus 1/2%, at the Company's option. There were no borrowings outstanding under these lines of credit at December 31, 1993 or 1992. The Company utilizes short-term bank loans to finance working capital requirements for certain business units. During 1993 and 1992, the weighted average amount of such borrowings was approximately $1,429,000 and $1,290,000, respectively, and the maximum short-term borrowings under these arrangements in 1993 and 1992 were approximately $7,395,000 and $3,174,000, respectively. The Company's various loan and note agreements contain certain financial covenants typical to such agreements relating to working capital and to consolidated tangible net worth. NOTE 8. INCOME TAXES Effective January 1, 1993, the Company changed its method of accounting for income taxes from the deferred method to the liability method required by Financial Accounting Standard No. 109 (FAS 109). As permitted under the new rule, prior years' financial statements have not been restated. The cumulative effect of adopting this Statement as of January 1, 1993 was immaterial to net income. The Company has elected not to provide tax on certain undistributed earnings of its foreign subsidiaries which it considers to be permanently reinvested. The cumulative amount of such unprovided taxes was approximately $369,000, $30,000 and $1,418,000 as of December 31, 1993, 1992 and 1991, respectively. Reduced tax payments resulting from allocating tax benefits associated with the exercise of stock options directly to additional paid-in capital totaled $576,000, $680,000 and $189,000 in 1993, 1992 and 1991, respectively. /63 The following is a summary of U.S. and non-U.S. income before income taxes and minority interest, the components of the provisions for income taxes and deferred income taxes and a reconciliation of the U.S. statutory income tax rate to the effective income tax rate. Income before income taxes and minority interest: Dollars in thousands 1993 1992 1991 U.S. $10,902 $ 9,753 $ 5,867 Non-U.S. 8,822 8,431 5,782 Income before income taxes and minority interest $19,724 $18,184 $11,649 Income tax provisions (benefits) consist of the following: Dollars in thousands 1993 1992 1991 Federal $2,124 $2,121 $ 2,603 Foreign 1,729 2,290 755 State 475 300 475 Current provision 4,328 4,711 3,833 Federal 528 (441) (1,061) Foreign 1,013 976 625 State 48 27 (135) Deferred provision (benefit) 1,589 562 (571) Provision for income taxes $5,917 $5,273 $ 3,262 Deferred tax provisions (benefits) consist of the following: Dollars in thousands 1993 1992 1991 U.S. tax on unremitted earnings (net of foreign tax credit ) $ 335 $ - $ - Use of installment method - - (744) Use of different book/tax contract accounting methods 257 (94) (1,090) Net reversal of deferred profit on sales to foreign subsidiaries 71 44 33 Use of accelerated depreciation 651 672 970 DISC dividend (197) (197) (197) Bad debt reserve activity 87 (76) 126 Other, net 385 213 331 Deferred tax provision (benefit) $1,589 $ 562 $ (571) /64 The United States statutory corporate tax rate is reconciled to the Company's effective tax rate as follows: 1993 1992 1991 U.S. Federal statutory rate 34.0% 34.0% 34.0% Foreign Sales Corporation (1.9) (2.2) (4.4) Tax exempt interest income (3.5) (3.7) - Provision on undistributed foreign earnings - 7.8 - Timing items completely reversed - (7.5) - State income taxes, net of federal tax benefit 1.8 1.2 1.9 Foreign income taxed at different rates (1.3) .3 (3.8) Other, net .9 (.9 ) .3 Effective tax rate 30.0% 29.0% 28.0% Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

Because certain provisions of the tax law may limit the utilization of these benefits, the Company has established a $1,800,000 valuation allowance at December 31, 1993. The net unused tax loss carryforward benefit of $4,540,000 has been included in other assets. /65 NOTE 9. STOCKHOLDERS' EQUITY The Company maintains two stock option plans. Under its 1979 Stock Option Plan (the "1979 Plan"), options may be granted to officers and other employees of the Company (either as non-qualified options or until February 15, 1989, as incentive stock options) and are exercisable at a price of not less than $1.00 per share. Any difference between the option price and the fair market value at the date of grant is charged to operations over the expected period of benefit to the Company. No additional shares of common stock were authorized for issuance as options during 1993. At December 31, 1993, 12,754 shares were reserved for issuance of additional options under the 1979 Plan. During 1992, an additional 70,000 shares of common stock were authorized for issuance as options under the 1986 Stock Option Plan for Non-Employee Directors (the "1986 Plan"). These options may be granted at a price not less than fair market value at the date of grant. No additional shares of common stock were authorized for issuance as options under the 1986 Plan during 1993. As of December 31, 1993, 67,000 shares were reserved for issuance of additional options under the 1986 Plan. The Company has also reserved 45,600 shares for options granted in 1990 to certain non-employees in exchange for a previously granted option to purchase 50% of the shares of Osmomar S.A., a Spanish subsidiary of the Company which was merged with Ionics Iberica, S.A. in 1992. A summary of changes in the total amount of outstanding options for the three years ended December 31, 1993 follows: 1993 1992 1991 Shares under option, beginning of year 530,375 555,780 361,769 Options granted 350,250 31,750 245,500 Options exercised (39,839) (55,480) (51,489) Options cancelled (8,000) (1,675) - Shares under option, end of year 832,786 530,375 555,780 Shares exercisable 800,866 493,895 514,740 Price range of options granted $39.50-48.75 $ 1.00-60.75 $40.13-46.25 Price range of options exercised $ 1.00-54.00 $11.00-43.00 $ 1.00-24.50 Price range of options exercisable $ 1.00-60.75 $ 1.00-60.75 $ 1.00-46.25 The Company also has a Section 401(k) stock savings plan under which 75,000 shares have been registered with the Securities and Exchange Commission for purchase on behalf of employees. Shares will normally be acquired for the plan in the open market. However, the Board of Directors has reserved an additional 60,000 shares for issuance by the Company from authorized but unissued shares if required. Through December 31, 1993, no shares had been issued under the plan. /66 The Company has adopted a Stockholder Rights Plan designed to protect stockholders against abusive takeover tactics. Rights were distributed as a dividend at the rate of one right for each share of the Company's stock. Each right entitles the holder to purchase from the Company one unit, consisting initially of one-fifth share of common stock and one note in principal amount equal to four-fifths of the current market price of the common stock on the date of exercise, at a purchase price of $50 subject to adjustment. In certain circumstances, rights cease to be exercisable for a unit and become exercisable for $100 worth of common stock (or a combination of cash, property or other securities of the Company) for $50. The rights are not exercisable until: (i) 10 days following a public announcement that a person or group has acquired 20 percent or more of the Company's common stock; or (ii) 10 business days following the commencement of a tender offer that could result in the person or group owning at least 30 percent of the Company's stock; or (iii) immediately after a declaration by the Company's independent directors that a person is an "Adverse Person," as defined in the Rights Plan. Subject to possible extension, the rights may be redeemed by the Company at $.01 per right at any time until 10 days after a public announcement that 20 percent or more of the Company's outstanding common stock has been acquired by a person or group. Unless redeemed earlier, the rights, which have no voting power, expire on December 31, 1997. NOTE 10. OPERATING LEASES The Company leases equipment, primarily triple-membrane trailers and bottled water coolers, to customers through operating leases. The original cost of this equipment was $37,555,000 and $27,657,000 at December 31, 1993 and 1992, respectively. The accumulated depreciation for such equipment was $9,914,000 and $6,173,000 at December 31, 1993 and 1992, respectively. At December 31, 1993, future minimum rentals receivable under noncancelable operating leases in the years 1994 through 1998 and later were approximately $5,582,000, $5,019,000, $4,019,000, $3,329,000, $2,705,000 and $7,745,000, respectively. NOTE 11. PROFIT SHARING AND PENSION PLANS The Company has a contributory profit-sharing plan covering substantially all of the employees of its Bridgeville, Pennsylvania operations and certain related operations. Company contributions are made from pre-tax profits and may vary from 8% to 15% of participants' compensation and are allocated to participantsU accounts in proportion to each participants' respective compensation. Company contributions were $381,000, $372,000 and $387,000 in 1993, 1992 and 1991, respectively. The Company also has a contributory defined benefit pension plan for its Watertown-based employees as well as personnel at Ionics Pure Solutions in Arizona, Ionics Ultrapure Water Corporation in California and Resources Conservation Company in Washington. The benefits are based on years of service and the employee's average compensation. The Company's funding policy is to contribute annually an amount that can be deducted for federal income tax purposes. /67 The following table sets forth the pension plan's funded status and amounts recognized in the Company's balance sheets at December 31, 1993 and 1992: Dollars in thousands 1993 1992 Actuarial present value of benefit obligations: Accumulated benefit obligation, including vested benefits of $6,447 and $5,734, respectively $6,778 $5,957 Projected benefit obligation for service rendered to date $7,736 $6,678 Plan assets at fair value 6,615 5,829 Projected benefit obligation in excess of plan assets 1,121 849 Unrecognized net loss (508) (287) Unrecognized prior service cost (120) (130) Unrecognized net assets being amortized over approximately 17 years 520 573 Accrued pension cost at December 31 $1,013 $1,005 Net pension cost included the following components: Dollars in thousands 1993 1992 1991 Service cost $568 $482 $386 Interest cost 556 512 478 Return on plan assets (632) (380) (886) Net amortization (deferral) 50 (137) 416 Net periodic pension cost $542 $477 $394 The discount rates used in determining the projected benefit obligation are 7.5% in 1993 and 8% in 1992. The rate of increase in compensation levels used is 6%. The expected long-term rate of return on assets was 9%. Plan assets consist primarily of money market, equity and fixed income securities and are administered by an independent trustee. The Company does not provide post-retirement health care to its employees or any other significant post-retirement benefits other than those described above. NOTE 12. FINANCIAL INSTRUMENTS Off-Balance-Sheet Risk The Company issues letters of credit as guarantees for various performance and bid obligations. Approximately $19.2 million and $5.2 million of these letters were outstanding at December 31, 1993 and 1992, respectively. Approximately 11% of the letters of credit outstanding at December 31, 1993 are scheduled to expire in 1994. The Company periodically enters into foreign exchange contracts to hedge certain operational and balance sheet exposures against changes in foreign currency exchange rates. Because the impact of movements in currency exchange rates on foreign exchange contracts offsets the related impact on the underlying items being hedged, these instruments do not subject the Company to risk that would otherwise result from changes in currency exchange rates. The Company had no foreign exchange contracts outstanding at December 31, 1993 and 1992. /68 Concentrations of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash equivalents, investments, trade accounts receivable and notes receivable. The credit risk of cash equivalents and investments is low as the funds are primarily invested in U.S. government securities and with major financial institutions. The Company's concentrations of credit risk with respect to trade accounts receivable and notes receivable is considered low. The Company's customer base is spread across many different industries and geographies and the Company obtains guaranteed letters of credit for many of its foreign orders. FAIR VALUE OF FINANCIAL INSTRUMENTS The carrying amounts of cash equivalents and investments closely approximates their fair values as these items have relatively short maturities and are highly liquid. Based on market information, the carrying amounts of notes receivable and debt approximates their fair values. INVESTMENTS IN SECURITIES In May 1993, the Financial Accounting Standards Board issued Financial Accounting Standard No. 115, "Accounting for Certain Investments in Debt and Equity Securities," which requires the expanded use of fair value accounting for certain investments in debt and equity securities. The Statement is effective for fiscal years beginning after December 15, 1993. The impact of adoption on the Company's financial position is not expected to be material. NOTE 13. CONSOLIDATION AND ACQUISITION AQUA COOL ENTERPRISES, INC. Prior to May 26, 1993, Aqua Cool Enterprises, Inc. ("ACE") was an independently owned distributor of the Company's Aqua Cool bottled water products. The Company sold bottled water and related supplies to ACE; leased coolers and vehicles to ACE; and provided management services and operational support to ACE. In addition to equipment lease financing it received from the Company, ACE had received $12.5 million in debt and preferred equity financing from Westinghouse Credit Corporation ("Westinghouse") over a three- year period beginning in 1989. Effective May 26, 1993, the Company loaned $8.25 million to ACE with which ACE subsequently redeemed the outstanding senior note and preferred stock of ACE held by Westinghouse. On June 10, 1993, the Company exchanged its $8.25 million loan to ACE for ACE preferred stock. The Company holds an option to acquire the outstanding common stock of ACE for a nominal amount. As a result of these transactions, the Company has consolidated the operating results of ACE as if ACE were a wholly owned subsidiary. ACE's results of operations are included in the Company's consolidated financial statements from May 26, 1993. The combination has been accounted for under the purchase method with goodwill of $12.2 million, net of federal income tax benefits of $4.5 million, being amortized on a straight-line basis over 40 years. /69 For purposes of presenting the following unaudited pro forma consolidated results all transactions between the Company and ACE have been eliminated as if the consolidation had occurred on January 1, 1992. The pro forma results also reflect adjustments that are attributable to the consolidation such as interest expense, goodwill amortization, operational efficiencies, asset revaluations and related tax effects. Twelve Months Ended December 31 (unaudited) 1993 1992 Net revenues $174,400 $155,569 Income before extraordinary items $ 12,702 $ 10,401 Net income $ 12,702 $ 10,401 Earnings per share $ 1.80 $ 1.50 RESOURCES CONSERVATION COMPANY Effective December 1, 1993, the Company acquired a substantial portion of the assets and liabilities of Resources Conservation Company (RCC) for approximately $10.9 million. RCC designs, engineers and installs wastewater treatment systems. The acquisition was accounted for under the purchase method with the results of RCC included from December 1, 1993. Goodwill of $8.3 million is being amortized on a straight-line basis over 40 years. Pro forma results of operations have not been presented as the effect of this acquisition on the financial statements was immaterial. Fiscal 1993 RCC revenues for the period prior to December 1, 1993 were approximately $25.3 million. Payment of the RCC purchase price of $10.9 million plus related interest expense of approximately $100,000 occurred on January 27, 1994. The obligation for payment plus related accrued interest was included in other current liabilities at December 31, 1993. NOTE 14.

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.
