2 PART I Item 1. Business Twin Disc designs, manufactures and sells heavy duty off-highway power transmission equipment. Products offered include: hydraulic torque converters; power-shift transmissions; marine transmissions and surface drives; universal joints; gas turbine starting drives; power take-offs and reduction gears; industrial clutches; fluid couplings and control systems. The Company sells its product to customers primarily in the construction equipment, industrial equipment, government, marine, energy and natural resources and agricultural markets. The Company's worldwide sales to both domestic and foreign customers are transacted through a direct sales force and a distributor network. There have been no significant changes in products or markets since the beginning of the fiscal year. The products described above have accounted for more than 90% of revenues in each of the last three fiscal years. Most of the Company's products are machined from cast iron, forgings, cast aluminum and bar steel which generally are available from multiple sources and which are believed to be in adequate supply. The Company has pursued a policy of applying for patents in both the United States and certain foreign countries on inventions made in the course of its development work for which commercial applications are considered probable. The Company regards its patents collectively as important but does not consider its business dependent upon any one of such patents. The business is not considered to be seasonal except to the extent that employee vacations are taken mainly in the months of July and August curtailing production during that period. The Company's products receive direct widespread competition, including from divisions of other larger independent manufacturers. The Company also competes for business with parts manufacturing divisions of some of its major customers. Ten customers accounted for approximately 47% of the Company's consolidated net sales during the year ended June 30, 2001. Sewart Supply, Inc., an independent distributor of Twin Disc products, accounted for approximately 11% of consolidated net sales in 2001. Unfilled open orders for the next six months of $39,405,000 at June 30, 2001 compares to $52,991,000 at June 30, 2000. Since orders are subject to cancellation and rescheduling by the customer, the six-month order backlog is considered more representative of operating conditions than total backlog. However, as procurement and manufacturing "lead times" change, the backlog will increase or decrease; and thus it does not necessarily provide a valid indicator of the shipping rate. Cancellations are generally the result of rescheduling activity and do not represent a material change in backlog. Management recognizes that there are attendant risks that foreign governments may place restrictions on dividend payments and other movements of money, but these risks are considered minimal due to the political relations the United States maintains with the countries in which the Company operates or the relatively low investment within individual countries. The Company's business is not subject to renegotiation of profits or termination of contracts at the election of the Government. Engineering and development costs include research and development expenses for new product development and major improvements to existing products, and other charges for ongoing efforts to refine existing products. Research and development costs charged to operations totaled $1,942,000, $1,852,000 and $2,505,000 in 2001, 2000, and 1999, respectively. Total engineering and development costs were $6,309,000, $6,322,000 and $7,829,000 in 2001, 2000 and 1999, respectively. Compliance with federal, state and local provisions regulating the discharge of materials into the environment, or otherwise relating to the protection of the environment, is not anticipated to have a material effect on capital expenditures, earnings or the competitive position of the Company. The number of persons employed by the Company at June 30, 2001 was 986. A summary of financial data by segment for the years ended June 30, 2001, 2000 and 1999 appears in Note J to the consolidated financial statements on pages 20 through 22 of this form. Item 2. Properties The Company owns two manufacturing, assembly and office facilities in Racine, Wisconsin, U.S.A. and one in Nivelles, Belgium. The aggregate floor space of these three plants approximates 677,000 square feet. One of the Racine facilities includes office space which is the location of the Company's corporate headquarters. The Company leases additional manufacturing, assembly and office facilities in Decima, Italy. The Company also has operations in the following locations, all of which are used for sales offices, warehousing and light assembly or product service. The following properties are leased: Jacksonville, Florida, U.S.A. Chambery, France Miami, Florida, U.S.A. Brisbane, Queensland, Australia

3 Loves Park, Illinois, U.S.A. Perth, Western Australia, Australia Coburg, Oregon, U.S.A. Singapore Kent, Washington, U.S.A. Shanghai, China Edmonton, Alberta, Canada Viareggio, Italy Vancouver, British Columbia, Canada The properties are generally suitable for operations and are utilized in the manner for which they were designed. Manufacturing facilities are currently operating at less than 65% capacity and are adequate to meet foreseeable needs of the Company. Item 3. Legal Proceedings Twin Disc is a defendant in several product liability or related claims considered either adequately covered by appropriate liability insurance or involving amounts not deemed material to the business or financial condition of the Company. The Company has joined with a group of potentially responsible parties in signing a consent decree with the Illinois Environmental Protection Agency ("IEPA") to conduct a remedial investigation and feasibility study at the Interstate Pollution Control facility in Rockford, Illinois. The consent decree was signed on October 17, 1991, and filed with the federal court in the Northern District of Illinois. The Company's total potential liability on the site cannot be estimated with particularity until a final remedy is selected by the IEPA and an allocation scheme is adopted by the parties. The IEPA is expected to issue its decision by early fall, 2001. Based upon current assumptions, however, the Company anticipates potential liability of approximately $200,000. The Company has also joined with a group of potentially responsible parties in signing a consent decree with the Illinois Environmental Protection Agency to conduct a remedial investigation and feasibility study at the MIG\DeWane Landfill in Rockford, Illinois. The consent decree was signed on March 29, 1991, and filed with the federal court in the Northern District of Illinois. The IEPA issued its record of decision for the site in April 2000, selecting a remedy with an estimated cost of $18 million. The Company's total potential liability on the site cannot be estimated with particularity until an allocation scheme is adopted by the parties. Based upon current assumptions, however, the Company anticipates potential liability of approximately $300,000. Item 4. Submission of Matters to a Vote of Security Holders None.

Each officer holds office until his successor is duly elected, or until he resigns or is removed from office. PART II Item 5. Market for the Registrant's Common Stock and Related Stockholder Matters The Company's common stock is traded on the New York Stock Exchange under the symbol TDI. The price information below represents the high and low sales prices for each period: Fiscal Year Ended June 30, 2001 Fiscal Year Ended June 30, 2000 High Low High Low First Quarter 17 13/16 15 3/4 First Quarter 20 3/8 16 1/2 Second Quarter 17 5/16 14 1/4 Second Quarter 16 5/8 11 Third Quarter 15 3/32 13 1/16 Third Quarter 18 5/16 11 7/8 Fourth Quarter 17 19/64 14 1/4 Fourth Quarter 17 9/16 15 7/16 Quarterly dividends of $0.175 per share were declared and paid for each of the quarters above. As of June 30, 2001 there were 1,060 shareholder accounts. Pursuant to a shareholder rights plan (the "Rights Plan"), on April 17, 1998, the Board of Directors declared a dividend distribution, payable to shareholders of record at the close of business on June 30, 1998, of one Preferred Stock Purchase Right ("Rights") for each outstanding share of Common Stock. The Rights will expire 10 years after issuance, and will be exercisable only if a person or group becomes the beneficial owner of 15% or more of the Common Stock (or 25% in the case of any person or group which currently owns 15% or more of the shares or who shall become the Beneficial Owner of 15% or more of the shares as a result of any transfer by reason of the death of or by gift from any other person who is an Affiliate or an Associate of such existing holder or by succeeding such a person as trustee of a trust existing on the record date) (an "Acquiring Person"), or 10 business days following the commencement of a tender or exchange offer that would result in the offeror beneficially owning 25% or more of the Common Stock. A person who is not an Acquiring Person will not be deemed to have become an Acquiring Person solely as a result of a reduction in the number of shares of Common Stock outstanding due to a repurchase of Common Stock by the Company until such person becomes beneficial owner of any additional shares of Common Stock. Each Right will entitle shareholders who received the Rights to buy one newly issued unit of one one-hundredth of a share of Series A Junior Preferred Stock at an exercise price of $160, subject to certain anti-dilution adjustments. The Company will generally be entitled to redeem the Rights at $.05 per Right at any time prior to 10 business days after a public announcement of the existence of an Acquiring Person. In addition, if (i) a person or group accumulates more than 25% of the Common Stock (except pursuant to an offer for all outstanding shares of Common Stock which the independent directors of the Company determine to be fair to and otherwise in the best interests of the Company and its shareholders and except solely due to a reduction in the number of shares of Common Stock outstanding due to the repurchase of Common Stock by the Company), (ii) a merger takes place with an Acquiring Person where the Company is the surviving corporation and its Common Stock is not changed or exchanged, (iii) an Acquiring Person engages in certain self-dealing transactions, or (iv) during such time as there is an Acquiring Person, an event occurs which results in such Acquiring Person's ownership interest being increased by more than 1% (e.g., a reverse stock split), each Right (other than Rights held by the Acquiring Person and certain related parties which become void) will represent the right to purchase, at the exercise price, Common Stock (or in certain circumstances, a combination of securities and/or assets) having a value of twice the exercise price. In addition, if following the public announcement of the existence of an Acquiring Person the Company is acquired in a merger or other business combination transaction, except a merger or other business combination transaction that takes place after the consummation of an offer for all outstanding shares of Common Stock that the independent directors of the Company have determined to be fair, or a sale or transfer of 50% or more of the Company's assets or earning power is made, each Right (unless previously voided) will represent the right to purchase, at the exercise price, common stock of the acquiring entity having a value of twice the exercise price at the time. The Rights may have certain anti-takeover effects. The Rights will cause substantial dilution to a person or group that attempts to acquire the Company without conditioning the offer on a substantial number of Rights being acquired. However, the Rights are not intended to prevent a take-over, but rather are designed to enhance the ability of the Board of Directors to negotiate with an acquirer on behalf of all of the shareholders. In addition, the Rights should not interfere with a proxy contest. The Rights should not interfere with any merger or other business combination approved by the Board of Directors since the Rights may be redeemed by the Company at $.05 per Right prior to 10 business days after the public announcement of the existence of an Acquiring Person. The news release announcing the declaration of the Rights dividend, dated April 17, 1998, filed as Item 14(a)(3), Exhibit 4(b) of Part IV of the Annual Report on Form 10-K for the year ended June 30, 1998 is hereby incorporated by reference.

Selected Financial Data Financial Highlights (dollars in thousands, except per share amounts and shares outstanding) For the years ended June 30, Statement of Operations Data: 2001 2000 1999 1998 1997 Net sales $180,786 $177,987 $168,142 $202,643 $189,942 Net earnings (loss) 6,169 3,773 (1,018) 9,363 7,729 Basic earnings (loss) per share 2.20 1.34 (.36) 3.30 2.78 Diluted earnings (loss) per share 2.20 1.34 (.36) 3.24 2.75 Dividends per share .70 .70 .805 .76 .70 Balance Sheet Data (at end of period): Total assets 156,734 174,190 176,900 160,954 158,755 Total debt 31,058 38,682 40,127 20,225 20,113 Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations Results of Operations Net Sales, New Orders and Backlog There was a small increase in revenues in fiscal 2001 following the modest improvement a year earlier. While sales improved, demand from our various markets was mixed and the strong dollar heightened competitive pressure. Order rates declined throughout the most recent fiscal year after an improvement in fiscal 2000. The backlog of orders scheduled for shipment during the next six months (six-month backlog) increased 32 percent to $53 million at June 2000 but dropped by 26 percent to $39 million by the end of fiscal 2001. Net sales of $178 million in fiscal 2000 were six percent ahead of the previous fiscal year and rose another two percent to $181 million in fiscal 2001. Order rates improved early in fiscal year 2000, and year-over-year improvements in shipments began in the second fiscal quarter. The most significant components of the year 2000 improvement were registered within our domestic manufacturing operation. Shipments of power take-offs, attributable to the product line purchased in fiscal 1999; higher-horsepower marine transmissions used in commercial boats; power-shift transmissions for construction applications; and aftermarket parts sales all contributed to the increase. Shipments from our Belgian plant of lower-horsepower marine transmissions also increased slightly as demand for their use in pleasure craft applications remained steady; and shipments from our Italian manufacturing subsidiary acquired in fiscal 1999 contributed for the full year. Demand continued at a steady pace for the first part of fiscal 2001, but eased somewhat by mid-year. Shipments followed the same pattern with favorable year-to-year comparisons during the first half in all forward market product lines as well as aftermarket service parts. As the year progressed, we experienced a softening demand for power-shift transmissions and torque converters and for power take-offs used in irrigation and waste recycling applications. These declines were partially offset by increased volume of shipments for military applications, surface drive marine propulsion units, and the continuing steady demand for marine transmissions produced overseas. Indicative of a modest recovery in certain of the Company's markets, fourth quarter shipments of power take-offs were approximately equal to year ago levels. Shipments from our wholly owned distribution companies, primarily those offshore, rebounded in fiscal 2000 after the modest decline in 1999; and that improvement continued in fiscal 2001. Recovering economies, particularly in the Pacific Rim, were a positive influence, but the stronger dollar intensified competition and inhibited realization of the full market potential. The U.S. dollar strengthened against most currencies in each of the last three fiscal years, particularly Asian currencies in fiscal 1999 and the Euro in fiscal 2000 and 2001, resulting in two negative influences on revenues. There was increased pricing pressure from non-dollar based competition, and sales from our offshore subsidiaries were down when translated into U.S. dollars for reporting. An offsetting favorable impact was the improved margins on dollar- denominated shipments from our Belgian subsidiary. Price increases, implemented selectively in each year, generated revenues about equal to the rate of inflation. At the end of fiscal 2000, six-month backlog was $53 million, a substantial increase from the prior year-end. The improvement was due mainly to improved demand for commercial marine and certain industrial products. As fiscal 2001 opened, order rates began to decline in selected markets, most notably industrial products, and that continued through the year. By the end of fiscal 2001 industrial products demonstrated evidence of some recovery in demand, but the order rate for marine transmissions had fallen. As a result, the six-month backlog at the end of fiscal 2001 had declined to $39 million, 26 percent below the prior year-end.

6 Margins, Costs and Expenses Manufacturing method and process improvements as well as programs to reduce inventory and manage assets more effectively have been part of our on-going efforts to improve operating margins. We also have given constant attention to fixed costs so that greater profitability can be achieved, especially during cyclical downturns. The gross margin increased by almost two percentage points in fiscal 2000 with all manufacturing operations showing improvement. Domestically, higher production volume, a favorable product mix, strict control of general manufacturing costs, and the cost benefit of fiscal 1999 manufacturing personnel reductions were the most significant factors. Overseas, productivity improvements, expansion of the production workweek, and the favorable impact of sales denominated in the relatively strong dollar provided added profitability. In fiscal 2001, incremental improvements in all aspects of our manufacturing operations from on-time delivery to inventory reduction and cellular layout led the way to higher gross margins. During the fourth quarter, we recorded several one-time charges against operations for inventory obsolescence and product warranty issues. Although the fourth-quarter margin was down somewhat from the comparable period a year ago, it was consistent with previous fiscal 2001 quarters. Marketing, engineering, and administrative (ME&A) expense declined four percent in fiscal 2000 as a result of previous-year staff reductions, continued attention to cost, and closure of our South African distribution operation. In fiscal 2001, ME&A was virtually unchanged from the previous year. Recognizing the reduced order activity in the latter half of fiscal year 2001, severance and voluntary separation programs to reduce the domestic manufacturing workforce were implemented in the fourth quarter. In addition, representing about one-third of the $1.5 million fourth quarter restructuring charge, reserves were taken for the rationalization of several smaller branches and operations whose markets will continue to be served from other locations. Early in fiscal 2001, we closed our wholly owned distribution company in Spain and engaged an existing company to represent Twin Disc in that market. The impact on revenues and profitability was not significant. During the third fiscal quarter, we sold our minority interest in Niigata Converter Company to our joint-venture partner and recorded a gain of $3.9 million in Other Income. Most of the proceeds were applied to the outstanding debt, but a portion was used to capitalize a new marketing and engineering joint venture that will support our global marine product line. Interest, Taxes and Net Earnings Interest expense increased sharply in fiscal 2000 primarily due to the increased debt needed to finance acquisitions in fiscal 1999. In fiscal 2001, interest declined as debt was reduced by $8 million and, although the majority of our debt is in fixed-rate notes, we also benefited from the drop in U.S. interest rates. In the last fiscal quarter, settlement of a federal tax issue allowed the reversal of previously accrued interest expense; and that further reduced fiscal 2001 interest expense. The substantial tax provision on almost-breakeven pre-tax earnings in fiscal 1999 was caused by lower tax rates on losses domestically, offset by higher rates on income overseas; and by the lack of a recordable tax benefit on the provision for loss on the closure of our South African distribution subsidiary. In fiscal 2000 and again in fiscal 2001, limitations on foreign tax credit utilization, continued high proportion of foreign earnings, and settlement of some state tax issues resulted in an unusually high effective tax rate. Statutory rates generally have remained unchanged. Liquidity and Capital Resources The net cash provided by operating activities in fiscal 2000 was almost $7 million, down approximately $2 million from the previous year. Positive cash flows from earnings, depreciation, and working capital reductions were partially offset by increased contributions to Company pension funds. In fiscal 2001, net cash provided by operations remained about $7 million with earnings, depreciation and asset reduction the primary components. Expenditures for capital equipment were reduced from plan to conserve cash during the fiscal 1999 downturn. For the past two years, spending has been well below depreciation as we have been more rigorous in establishing capital budgets that are consistent with long-term manufacturing strategy. Looking forward, we expect the level of capital spending will rise as necessary to provide for more efficient machinery and to allow further refinement of individual manufacturing cells. Working capital and the current ratio dropped in fiscal 1999 as short-term debt was used to finance acquisitions. Early in fiscal 2000, the short-term borrowings were replaced with a term revolver and those liquidity measures returned to more normal levels. At the end of each of the last two fiscal years, working capital has been approximately $50 million with the current ratio unchanged at 2.2. The book value of the Company, and thus its reported capital structure, changed significantly at each of the last three fiscal year-ends. It was reduced by a non-cash charge to equity of $11.1 million at June 30, 1999. The charge was caused primarily by using a more conservative mortality table to

7 estimate pension liabilities and generally reflected the amount by which those liabilities exceeded plan assets. In fiscal 2000, the charge was reversed as a result of good market return on plan assets and equity increased by a similar amount. Then in the most recent year, poor market performance reduced plan assets and required a new non-cash charge to equity of $17.8 million, net of tax. In accordance with applicable accounting standards, the after-tax effects of the changes were charged directly to equity and shown in comprehensive income but did not affect reported primary earnings. In addition, the aforementioned non-cash accounting adjustment reflects, in large part, a mismatch between cash contributed to the plan and the expense charged against operations and does not indicate a need for large cash contributions. Our pension plans are well funded. The Company believes the capital resources available in the form of existing cash, lines of credit (see Footnote G to the consolidated financial statements), and funds provided by operations will be adequate to meet anticipated capital expenditures and other foreseeable business requirements in the future. Other Matters Environmental Matters The Company is involved in various stages of investigation relative to hazardous waste sites on the United States EPA National Priorities List. It is not possible at this time to determine the ultimate outcome of those matters; but, as discussed further in Footnote O to the consolidated financial statements, they are not expected to affect materially the Company's operations, financial position, or cash flows. Note on Forward-Looking Statements Statements in this report and in other Company communications that are not historical facts are forward-looking statements, which are based on management's current expectations. These statements involve risks and uncertainties that could cause actual results to differ materially from what appears here. Forward-looking statements include the Company's description of plans and objectives for future operations and assumptions behind those plans. The words "anticipates," "believes," "intends," "estimates," and "expects," or similar anticipatory expressions, usually identify forward-looking statements. In addition, goals established by Twin Disc, Incorporated, should not be viewed as guarantees or promises of future performance. There can be no assurance the Company will be successful in achieving its goals. In addition to the assumptions and information referred to specifically in the forward-looking statements, other factors could cause actual results to be materially different from what is presented here. Item 7(a). Quantitative and Qualitative Disclosure About Market Risk. The Company is exposed to market risks from changes in interest rates, commodities and foreign exchange. To reduce such risks, the Company selectively uses financial instruments and other pro-active management techniques. All hedging transactions are authorized and executed pursuant to clearly defined policies and procedures, which prohibit the use of financial instruments for trading or speculative purposes. Discussions of the Company's accounting policies and further disclosure relating to financial instruments is included in Note A of Notes to Consolidated Financial Statements on pages 16 through 17 of this form. Interest rate risk - The Company currently has lines of credit bearing interest predominantly at the prime interest rate minus .75%. Due to the relative stability of interest rates, the Company does not utilize any financial instruments to manage interest rate risk exposure. Commodity price risk - The Company is exposed to the fluctuation in market prices for such commodities as steel and aluminum. Due to the relative stability of these commodities, the Company does not utilize commodity price hedges to manage commodity price risk exposure. Currency risk - The Company has exposure to foreign currency exchange fluctuations. The Company does not hedge the translation exposure represented by the net assets of its foreign subsidiaries. Foreign currency translation adjustments are recorded as a component of shareholders' equity. Forward foreign exchange contracts are used to hedge the currency fluctuations on transactions denominated in foreign currencies. Gains and losses from foreign currency transactions are included in earnings. At June 30, 2001 and 2000, the Company had outstanding forward exchange contracts to purchase 208,189,000 and 189,972,000 Belgian francs at a cost of $4,500,000 and $4,500,000, respectively. The contracts have a weighted average maturity of 48 days and 40 days, respectively. In addition, the Company had outstanding forward foreign exchange contracts to sell 776,913,000 Italian Lira for $345,000. The contracts have a weighted average maturity of 21 days as of June 30, 2001.

15 TWIN DISC, INCORPORATED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS A. SIGNIFICANT ACCOUNTING POLICIES The following is a summary of the significant accounting policies followed in the preparation of these financial statements: Consolidation Principles--The consolidated financial statements include the accounts of Twin Disc, Incorporated and its wholly and partially owned domestic and foreign subsidiaries. Certain foreign subsidiaries are included based on fiscal years ending March 31 or May 31, to facilitate prompt reporting of consolidated accounts. All significant intercompany transactions have been eliminated. Translation of Foreign Currencies--Substantially all foreign currency balance sheet accounts are translated into United States dollars at the rates of exchange prevailing at year-end. Revenues and expenses are translated at average rates of exchange in effect during the year. Foreign currency translation adjustments are recorded as a component of shareholders' equity. Gains and losses from foreign currency transactions are included in earnings. Included in other income (expense) of the consolidated statement of operations are foreign currency transaction losses of $145,000, $144,000 and $682,000 in 2001, 2000 and 1999, respectively. Cash Equivalents--The Company considers all highly liquid marketable securities purchased with a maturity date of three months or less to be cash equivalents. Receivables--Trade accounts receivable are stated net of an allowance for doubtful accounts of $699,000 and $704,000 at June 30, 2001 and 2000, respectively. Fair Value of Financial Instruments--The carrying amount reported in the consolidated balance sheets for cash and cash equivalents, accounts receivable, accounts payable, notes payable and current maturities on long- term debt approximate fair value because of the immediate short-term maturity of these financial instruments. The carrying amounts reported for long-term debt approximates fair value because the underlying instruments bear interest at, or near, a current market rate. Derivative Financial Instruments--Derivative financial instruments (primarily forward foreign exchange contracts) may be utilized by the Company to hedge foreign exchange rate risk. The Company has established policies and procedures for risk assessment and the approval, reporting and monitoring of derivative financial instrument activities. The Company does not enter into financial instruments for trading or speculative purposes. For financial reporting purposes, forward foreign exchange contracts used to hedge the currency fluctuations on transactions denominated in foreign currencies are marked-to-market and the resulting gains and losses, together with the offsetting losses and gains on hedged transactions, are recorded in the "Other income (expense)" caption in the statement of operations. At June 30, 2001 and 2000, the Company had outstanding forward foreign exchange contracts to purchase $4,500,000 and $4,500,000, respectively, of Belgian francs with a weighted average maturity of 48 days and 40 days, respectively. In addition, the Company had outstanding forward foreign exchange contracts to sell $345,000 of Italian lira with a weighted average maturity of 21 days as of June 30, 2001. The Company adopted the provisions of Statement of Financial Accounting Standards (SFAS) No. 133 "Accounting for Derivative Instruments and Hedging Activities " which establishes standards for accounting for derivatives and hedging activities. FAS 133 was effective for the Company on July 1, 2000 and did not have a significant impact on the Company's earnings or financial position. Inventories--Inventories are valued at the lower of cost or market. Cost has been determined by the last-in, first-out (LIFO) method for parent company inventories, and by the first-in, first-out (FIFO) method for all other inventories. Property, Plant and Equipment and Depreciation--Assets are stated at cost. Expenditures for maintenance, repairs and minor renewals are charged against earnings as incurred. Expenditures for major renewals and betterments are capitalized and amortized by depreciation charges. Depreciation is provided on the straight-line method over the estimated useful lives of the assets for financial reporting and on accelerated methods for income tax purposes. The lives assigned to buildings and related improvements range from 10 to 40 years, and the lives assigned to machinery and equipment range from 5 to 15 years. Upon disposal of property, plant and equipment, the cost of the asset and the related accumulated depreciation are removed from the accounts and the resulting gain or loss is reflected in earnings. Fully depreciated assets are not removed from the accounts until physically disposed. The Company reviews the carrying value of property, plant and equipment for impairment whenever events and circumstances indicate that the carrying value of an asset may not be recoverable from the estimated future cash flows expected to result from its use and eventual disposition. In cases where undiscounted expected future cash flows are less than the carrying value, an impairment loss is recognized equal to an amount by which the carrying value exceeds the fair value of assets. Investments in Affiliates--The majority of the Company's investments in 20% to 50%-owned affiliates are accounted for using the equity method. Investments in less than 20%-owned affiliates are accounted for using the cost method. Revenue Recognition--Revenue is recognize by the Company when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred and ownership has transferred to the customer; the price to the customer is fixed or determinable; and collectability is reasonably assured. In December 1999, the Securities and Exchange Commission (SEC) released Staff Accounting Bulletin No. 101 (SAB 101), "Revenue Recognition in Financial Statements". SAB 101 was effective for the Company in the fourth quarter of 2001 and did not have a material effect on the Company's financial statements.

16 Goodwill--Goodwill consists of costs in excess of net assets of businesses acquired. Goodwill is amortized using the straight-line method over its estimated beneficial lives, not to exceed 40 years. Subsequent to an acquisition, the Company continually evaluates whether later events and circumstances have occurred that indicate whether the goodwill should be evaluated for possible impairment. Goodwill at June 30, 2001 and 2000 of $13,719,000 and $14,401,000, respectively, are net of accumulated amortization of $1,397,000 and $1,542,000, respectively. Income Taxes--The Company recognizes deferred tax liabilities and assets for the expected future income tax consequences of events that have been recognized in the Company's financial statements. Under this method, deferred tax liabilities and assets are determined based on the temporary differences between the financial statement carrying amounts and the tax bases of assets and liabilities using enacted tax rates in effect in the years in which the temporary differences are expected to reverse. The Company does not provide for taxes which would be payable if undistributed earnings of its foreign subsidiaries or its foreign affiliate were remitted because the Company either considers these earnings to be invested for an indefinite period or anticipates that if such earnings were distributed, the U.S. income taxes payable would be substantially offset by foreign tax credits. Management Estimates--The preparation of 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 liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual amounts could differ from those estimates. Shipping and Handling Fees and Costs--The Company adopted the provisions of the Emerging Issues Task Force (EITF) Issue No. 00-10 "Accounting for Shipping and Handling Fees and Costs". EITF 00-10 was effective for the Company in the fourth quarter of 2001 and did not have a material effect on the Company's financial statements. Recently Issued Accounting Standards--In July 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards (SFAS) No. 141, "Business Combinations" and No. 142, "Goodwill and Other Intangible Assets." The statements eliminate the pooling-of-interest method of accounting for business combinations and require that goodwill and certain intangible assets not be amortized. Instead, these assets will be reviewed for impairment annually with any related losses recognized in earnings when incurred. SFAS 141 is effective for the Company July 1, 2001. SFAS 142 will be effective for the Company July 1, 2002. Early application is permitted. The Company is currently evaluating the impact of SFAS 142. B. INVENTORIES The major classes of inventories at June 30 were as follows (in thousands): 2001 2000 ---- ---- Finished parts $37,711 $40,313 Work-in-process 4,931 5,880 Raw materials 3,850 3,997 ------ ------ $46,492 $50,190 ====== ====== Inventories stated on a LIFO basis represent approximately 29% and 35% of total inventories at June 30, 2001 and 2000, respectively. The approximate current cost of the LIFO inventories exceeded the LIFO cost by $20,565,000 and $20,549,000 at June 30, 2001 and 2000, respectively. C.

17 D. INVESTMENTS IN AFFILIATES The Company's investments in affiliates as of June 30, 2001 consists of a 25% interest in a domestic distributor of Twin Disc products. The Company's investments in affiliates as of June 30, 2000 consisted of the 25% interest in the domestic distributor and a 19.5% investment in Niigata Converter Company, LTD., Japan (Niigata), a manufacturer of power transmission equipment. In March of 1999, the Company sold a portion of its investment in Niigata in exchange for a $1.7 million note receivable due in various annual amounts commencing December 31, 2002 through December 31, 2008. The sale was a non- cash transaction for purposes of the consolidated statement of cash flows. As a result, a pre-tax gain of $1.3 million was recognized in 1999. In January of 2001 the Company sold their remaining investment in Niigata. The total proceeds from the transaction was $7.2 million, including the elimination of the $1.7 million note receivable, and resulted in a pre-tax gain of $3.9 million recognized in 2001. Prior to the sale in 1999 the Company accounted for its 25% interest in Niigata using the equity method. The Company recognized its share of Niigata's loss from April 1, 1998 through March 1, 1999 of $1.5 million. Combined condensed financial data for investments in affiliates accounted for under the equity method of accounting are summarized below (in thousands).

The Company acquired 2,058 and 25,444 shares of treasury stock in 2001 and 2000, respectively. Cash dividends per share were $.70 in 2001, $.70 in 2000 and $.805 in 1999. In 1998, the Company's Board of Directors established a Shareholder Rights Plan and distributed to shareholders one preferred stock purchase right for each outstanding share of common stock. Under certain circumstances, a right may be exercised to purchase one one-hundredth of a share of Series A Junior Preferred Stock at an exercise price of $160, subject to certain anti-dilution adjustments. The rights become exercisable ten (10) days after a public announcement that a party or group has either acquired at least 15% (or at least 25% in the case of existing holders who currently own 15% or more of the common stock), or commenced a tender offer for at least 25% of the Company's common stock. Generally, after the rights become exercisable, if the Company is a party to certain merger or business combination transactions, or transfers 50% or more of its assets or earnings power, or certain other events occur, each right will entitle its holders, other than the acquiring person, to buy a number of shares of common stock of the Company, or of the other party to the transaction, having a value of twice the exercise price of the right. The rights expire June 30, 2008, and may be redeemed by the Company for $.05 per right at any time until ten (10) days following the stock acquisition date. The Company is authorized to issue 200,000 shares of preferred stock, none of which have been issued. The Company has designated 50,000 shares of the preferred stock for the purpose of the Shareholder Rights Plan.

19 J. BUSINESS SEGMENTS AND FOREIGN OPERATIONS The Company and its subsidiaries are engaged in the manufacture and sale of power transmission equipment. Principal products include industrial clutches, hydraulic torque converters, fluid couplings, power-shift transmissions, marine transmissions, universal joints, power take-offs and reduction gears. The Company sells to both domestic and foreign customers in a variety of market areas, principally construction, industrial, energy and natural resources, marine and agricultural. The Company has two reportable segments: manufacturing and distribution. These segments are managed separately because each provides different services and requires different technology and marketing strategies. The accounting practices of the segments are the same as those described in the summary of significant accounting policies. Transfers among segments are at established inter-company selling prices. Information about the Company's segments is summarized as follows (in thousands): Manufacturing Distribution Total ------------- ------------ ----- 2001 Net sales $171,439 $45,337 $216,776 Intra-segment sales 7,953 304 8,257 Inter-segment sales 27,009 724 27,733 Interest income 393 76 469 Interest expense 2,796 107 2,903 Income taxes 4,072 851 4,923 Depreciation and amortization 5,997 269 6,266 Segment earnings 5,562 1,365 6,927 Segment assets 141,737 24,822 166,559 Expenditures for segment assets 3,245 247 3,492 2000 Net sales $166,067 $46,726 $212,793 Intra-segment sales 7,176 613 7,789 Inter-segment sales 26,327 690 27,017 Interest income 321 73 394 Interest expense 3,159 125 3,284 Income taxes 3,904 916 4,820 Depreciation and amortization 6,589 264 6,853 Segment earnings 3,464 1,587 5,051 Segment assets 154,971 24,518 179,489 Expenditures for segment assets 1,766 368 2,134 1999 Net sales $156,661 $41,426 $198,087 Intra-segment sales 7,235 439 7,674 Inter-segment sales 21,545 726 22,271 Interest income 350 92 442 Interest expense 2,134 228 2,362 Income taxes 519 1,036 1,555 Depreciation and amortization 6,062 291 6,353 Segment earnings 1,147 170 1,317 Segment assets 152,251 25,448 177,699 Expenditures for segment assets 6,017 422 6,439

K. STOCK OPTION PLANS During fiscal 1999, the Company adopted the Twin Disc, Incorporated 1998 Stock Option Plan for Non-Employee Directors, a non-qualified plan, for non-employee directors to purchase up to 35,000 shares of common stock, and the Twin Disc, Incorporated 1998 Incentive Compensation Plan, a plan, where options are determined to be non-qualified or incentive at the date of grant, for officers and key employees to purchase up to 165,000 shares of common stock. The plans are administered by the Executive Selection and Compensation Committee of the Board of Directors which has the authority to determine which officers and key employees will be granted options. The grant of options to non-employee directors is fixed at options to purchase 1,000 shares of common stock per year or 600 at time of appointment. Except as described in the following sentence, all options allow for exercise prices not less than the grant date fair market value, immediately vest and expire ten years after the date of grant. For options under the Incentive Compensation Plan, if the optionee owns more than 10% of the total combined voting power of all classes of the Company's stock, the price will be not less than 110% of the grant date fair market value and the options expire five years after the grant date. In addition, the Company has 78,750 incentive stock option plan options and 56,250 non-qualified stock option plan options outstanding at June 30, 2001 under the Twin Disc, Incorporated 1988 Incentive Stock Option plan and the Twin Disc, Incorporated 1988 Non-Qualified Stock Option Plan for Officers, Key Employees and Directors, respectively.

Accordingly, no compensation cost has been recognized in the statement of operations. Had the Company recognized compensation expense determined based on the fair value at the grant date for awards under the plans, consistent with the method prescribed by FAS 123, the net earnings and earnings per share would have been as follows (in thousands, except per share amounts): 2001 2000 1999 ---- ---- ---- Net earnings (loss) As reported $ 6,169 $ 3,773 $(1,018) Pro forma 6,028 3,648 (1,277) Basic earnings (loss) per share As reported $ 2.20 $ 1.34 $ (.36) Pro forma 2.15 1.29 (.45) Diluted earnings (loss) per share As reported $ 2.20 $ 1.34 $ (.36) Pro forma 2.15 1.29 (.45) The above pro forma net earnings and earnings per share were computed using the fair value of options at the date of grant (for options granted after June 1995) as calculated by the Black-Scholes option-pricing method and the following assumptions: 22% volatility, 4.2% annual dividend yield, interest rates based on expected terms and grant dates, a 5 year term and an exercise price equal to the fair market value on the date of grant except for incentive options granted to greater than 10% shareholders which are calculated using a 3 year term and an exercise price equal to 110% of the fair market value on the date of grant. For those options granted during 2001, 2000 and 1999 with exercise prices equal to the grant date fair market value, the exercise prices and weighted average fair values of the options were $17.54 and $3.38 in 2001, $19.94 and $3.70 in 2000 and $25.26 and $5.02 in 1999, respectively. For those options granted with exercise prices greater than the grant date fair market value, the exercise prices and weighted average fair values of the options were $19.59 and $2.50 in 2001,$21.93 and $2.43 in 2000 and $28.08 and $2.71 in 1999,respectively.

23 L.

Total engineering and development costs were $6,309,000, $6,322,000 and $7,829,000 in 2001, 2000 and 1999, respectively. M. RETIREMENT PLANS The Company has non-contributory, qualified defined benefit pension plans covering substantially all domestic employees and certain foreign employees. Domestic plan benefits are based on years of service, and, for salaried employees, on average compensation for benefits earned prior to January 1, 1997 and on a cash balance plan for benefits earned after January 1, 1997. The Company's funding policy for the plans covering domestic employees is to contribute an actuarially determined amount which falls between the minimum and maximum amount that can be contributed for federal income tax purposes. Domestic plan assets consist principally of listed equity and fixed income securities. In addition, the Company has unfunded, non-qualified retirement plans for certain management employees and directors. Benefits are based on final average compensation and vest upon retirement from the Company. In addition to providing pension benefits, the Company provides health care and life insurance benefits for certain domestic retirees. All employees retiring after December 31, 1992, and electing to continue coverage through the Company's group plan, are required to pay 100% of the premium cost. The following table sets forth the Company's defined benefit pension plans' and other postretirement benefit plan's funded status and the amounts recognized in the Company's balance sheets and income statements as of June 30 (dollars in thousands): Other Post Pension retirement Benefits Benefits ---------------- -------------- 2001 2000 2001 2000 ---- ---- ---- ---- Change in benefit obligation: Benefit obligation, beginning of year $109,087 $115,865 $ 30,227 $ 32,749 Service cost 1,284 1,518 16 19 Interest cost 8,333 8,028 2,298 2,265 Actuarial (gain) loss 4,094 (6,806) 3,110 (1,481) Benefits paid (8,773) (9,518) (3,684) (3,325) ------- ------- ------ ------ Benefit obligation, end of year $114,025 $109,087 $ 31,967 $ 30,227 ======= ======= ====== ====== Change in plan assets: Fair value of assets, beginning of year $112,689 $ 98,283 $ - $ - Actual return on plan assets (11,560) 16,876 - - Employer contribution 5,996 7,048 3,684 3,325 Benefits paid (8,773) (9,518) (3,684) (3,325) ------- ------- ------ ------ Fair value of assets, end of year $ 98,352 $112,689 $ - $ - ======= ======= ====== ====== Funded status $(15,673)$ 3,602 $(31,967)$(30,227) Unrecognized net transition obligation 375 606 - - Unrecognized actuarial loss 30,008 4,398 9,582 6,817 Unrecognized prior service cost 1,823 2,495 - - ------ ------ ------ ------- Net amount recognized $ 16,533 $ 11,101 $(22,385)$(23,410) ====== ====== ====== ======= Amounts recognized in the balance sheet consist of: Prepaid benefit cost $ 6 $ 14,335 $ - $ - Accrued benefit liability (14,578) (3,234) (22,385) (23,410) Intangible asset 1,988 - - - Deferred tax asset 11,356 - - - Minimum pension liability adjustment 17,761 - - - ------- ------ ------- ------- Net amount recognized $ 16,533 $ 11,101 $(22,385)$(23,410) ======= ====== ======= ======= Weighted average assumptions as of June 30: Discount rate 7.50% 8.00% 7.50% 8.00% Expected return on plan assets 9.00% 9.00% Rate of compensation increase 5.00% 5.00%

The assumed weighted average health care cost trend rate was 6% in fiscal year 2001 and 2000. A 1% increase in the assumed health care cost trend would increase the accumulated postretirement benefit obligation by approximately $2.1 million and the service and interest cost by approximately $160,000. A 1% decrease in the assumed health care cost trend would decrease the accumulated postretirement benefit obligation by approximately $2.0 million and the service and interest cost by approximately $150,000. The Company sponsors defined contribution plans covering substantially all domestic employees and certain foreign employees. These plans provide for employer contributions based primarily on employee participation. The total expense under the plans was $1,591,000, $1,699,000 and $1,572,000 in 2001, 2000 and 1999, respectively. N.

O. CONTINGENCIES The Company is involved in various stages of investigation relative to hazardous waste sites, two of which are on the United States EPA National Priorities List (Superfund sites). The Company's assigned responsibility at each of the Superfund sites is less than 3%. The Company has also been requested to provide administrative information related to two other potential Superfund sites but has not yet been identified as a potentially responsible party. Additionally, the Company is subject to certain product liability matters in the normal course of business. At June 30, 2001, the Company has accrued approximately $1,050,000, which represents management's best estimate available for possible losses related to these contingencies. This amount has been provided over the past several years. Based on the information available, the Company does not expect that any unrecorded liability related to these matters would materially affect the consolidated financial position, results of operations or cash flows. P. RESTRUCTURING OF OPERATIONS During the fourth quarter of 2001, the Company recorded a pre-tax restructuring charge of $1.5 million in connection with the reduction of its workforce and consolidation of facilities. These actions were taken in an effort to streamline the Company's cost structure and utilization of available capacity at other locations. The charge included $1.0 million in employee termination and severance benefits, $0.3 million for remaining costs related to preexisting leases, $0.1 million for the estimated loss on fixed assets which were held for disposal, and $0.1 million in miscellaneous costs. During

26 2001 the Company had cash payments of $0.2 million and has a remaining balance in accrued liabilities of $1.3 million. Q. CLOSURE OF SUBSIDIARIES In June 1999, the Company approved a plan to terminate operations at its South African subsidiary, Twin Disc (South Africa) Pty. Ltd, early in fiscal 2000. The Company recorded a loss of $1,140,000 in 1999 related to the termination of operations, which consists primarily of the recognition of cumulative translation losses of $829,000 with the remaining amounts related to disposals of inventories and fixed assets, and severance benefits. The results of the subsidiary's operations through June 30, 1999 are included in the consolidated financial statements.
