PART I

Item 1. Business.

General

Detroit Diesel Corporation (the “Company”, “Detroit Diesel” or “DDC”) designs, manufactures, markets, services and provides aftermarket and remanufactured products for a full range of high performance diesel and alternative fuel engines. The Company offers a complete line of diesel engines from 22 to 11,000 horsepower for the on-highway, off-road (including power generation) and automotive markets through a worldwide network of more than 2,700 authorized distributor and dealer locations. The Company primarily sells its engines directly to original equipment manufacturers (“OEMs”). In 1999, approximately 71% of the Company’s net revenues were derived from sales made directly to U.S.-based customers, with the balance sold to international accounts. A portion of U.S. sales were exported as part of equipment built by U.S. customers.

Detroit Diesel Remanufacturing Corporation, a wholly-owned subsidiary of DDC, remanufactures four-cycle and two-cycle engines and component parts at facilities located in Tooele, Utah; Emporia, Kansas; Cambridge, Ohio; and Grand Rapids, Michigan. Remanufactured products are sold directly to the Company’s authorized distributors through the Company’s Parts Distribution Center in Canton, Ohio, under the Company’s reliabilt(R) tradename.

Detroit Diesel’s world headquarters is located in Detroit, Michigan. The Company operates diesel engine manufacturing plants in Redford, Michigan and Cento, Italy and engine assembly facilities in Emporia, Kansas and Curitiba, Brazil. Additionally, the Company operates a worldwide Parts Distribution Center in Canton, Ohio, complemented by service parts warehouses located in the Netherlands and in Singapore.

The Company was incorporated in the State of Delaware on November 23, 1987.

Products

The following table shows the number of heavy-duty engines, light-duty engines, and other engines sold by the Company during the periods indicated:


		Years Ended December 31,
(Units)		1999		1998		1997

Heavy-Duty			101,993		92,049		83,020




Light-Duty			62,370		61,226		76,946




Other engines			2,337		2,760		3,225

	Total		166,700		156,035		163,191

The Company offers the following heavy-duty four-cycle engines: the Series 60 engine, the Series 50 engine, the DDC/MTU Series 2000 (“Series 2000”) engine and the MTU/DDC Series 4000 (“Series 4000”) engine. The Series 60 is a six-cylinder engine offering a horsepower range of 300 to 700 horsepower. The Series 50 is a four-cylinder version of the Series 60 engine offering 250 to 320 horsepower. The Series 2000 and Series 4000 engines are available in eight, twelve and sixteen-cylinder configurations and offer horsepower ranges from 490 to 3,650 horsepower.

The Series 60 engine is the Company’s highest volume heavy-duty engine product, accounting for approximately 52%, 46% and 41% of the Company’s net revenues in 1999, 1998 and 1997, respectively. The Series 60 engine is sold primarily in the on-highway market, however, the Company sells this product in other market applications such as marine, construction and industrial, and power generation. The Series 50 engine is also principally sold in the on-highway market, but has expanded into other markets as the Company targets applications that have horsepower requirements below the Series 60 range. The Series 2000 and Series 4000 engines are designed to service the Company’s off-road market segments including construction and industrial, marine and power generation. The Series 60, Series 50, Series 2000 and Series 4000 engines feature integral electronic controls known as Detroit Diesel Electronic Controls (“DDEC”), consisting of an electronic control module and electronic fuel injection systems. The Company also continues to sell selected two-cycle engines to the military under long-term supply arrangements.

During 1998 the Company introduced its PowerEvolution program. PowerEvolution represents a comprehensive remake of the Company’s off-road products and services designed to update product technology, broaden its power range, improve efficiency and increase shareholder value. This program is a proactive response to the changing market needs and transitioned the Company’s customers to four-cycle products from two-cycle products. The Company continues to produce two-cycle products to the extent required under long-term contracts and will continue to support existing customer service parts requirements for the foreseeable future. The success of this transition was highlighted this year by DDC increasing top line sales by 5% year over year while experiencing a reduction in two-cycle sales of $114 million.

VM Motori S.p.A. (“VM”), located in Cento, Italy, is a wholly owned subsidiary of Detroit Diesel and is a major independent supplier of diesel engines to the international automotive industry. The principal product for the light-duty sector is a high-performance 2.5-liter, 4-cylinder, turbocharged diesel engine, which is currently being used in passenger cars, mini-vans, four-wheel drive and multi-purpose vehicles. Detroit Diesel Motores do Brasil Ltda. (“DDMB”) is a wholly owned subsidiary of Detroit Diesel located in Curitiba, Brazil. DDMB currently assembles the 2.5-liter, 4-cylinder automotive diesel engine manufactured by VM. DDMB and VM have significant sales relationships with DaimlerChrysler AG to provide automotive diesel engines for both the Latin American and European markets for use in Chrysler products.

The Company also markets medium-duty diesel engines built in the United States by Navistar International Transportation Corp. for market applications in which the Company does not compete with Navistar. The Company’s distribution rights include applications that serve NAFTA and other worldwide markets. Within NAFTA, the Company serves the transit bus industry, generator set and specialty on-highway applications such as custom fire trucks, motor homes, refuse vehicles, and trailer spotters. Outside NAFTA, the Company serves the same applications, plus commercial on-highway vehicle manufacturers.

In addition to its diesel-fueled engines, the Company currently offers natural gas fueled engine products, service parts, remanufactured components and engines as well as high horsepower gas turbine products. The Company also sells to licensees completely knocked-down and semi knocked-down unassembled engine kits for sale within selected markets.

Markets and Customers

Detroit Diesel serves the on-highway, off-road and automotive markets. Following is a brief description of these markets.

On-Highway. The largest market for the Company’s engines continues to be the on-highway heavy-duty market. This market is served primarily by the Company’s four-cycle products. The Series 60 engine is the Company’s highest volume engine for this use, accounting for the greatest share of the Company’s on-highway unit sales in 1999. The Company’s engines are available through all major North American heavy-duty truck manufacturers. The Company’s largest OEM customers for this market in 1999 were Freightliner Corporation, Navistar International Transportation Corp., Volvo GM Heavy Truck Corporation and PACCAR Inc. which collectively represented approximately 49% of the Company’s 1999 consolidated net revenues. Sales to Freightliner Corporation represented approximately 58% of this total. The loss of any of these customers could have an adverse effect on the Company’s business.

The on-highway market also consists of sales for bus and coach applications. This market is served primarily by the Company’s four-cycle products. The Company’s engines are available through all major North American heavy-duty bus manufacturers. The Series 50 and Series 60 engines are DDC’s main offering. The market is separated into transit bus, where DDC has a 65% market penetration level, and the highway coach market where DDC has a 90% penetration level.

Off-Road. The off-road market consists of a variety of applications, including construction, forestry, mining, earth moving, material handling, stationary mechanical power, petroleum, commercial and pleasure craft marine, power generation, and military combat and tactical vehicles. Traditionally, the Company’s two-cycle products have had a strong presence in this market. With the initiation of PowerEvolution and the introduction of the Series 2000 and Series 4000 engines, four-cycle products are rapidly gaining market acceptance. The Company’s products are available from a variety of OEMs and Detroit Diesel distributors worldwide.

Automotive. VM and DDMB currently serve the automotive market. These two subsidiaries sell state-of-the-art turbo diesel engines to OEMs primarily for use in the European and Latin American markets that are used in passenger cars, mini-vans, trucks and sport utility vehicles. The Company’s largest customer in this market is DaimlerChrysler. The Company is currently pursuing new opportunities with automotive OEMs to expand the customer base and geographic penetration of the automotive engines marketed by VM and DDMB. Additionally, DDC has developed two new automotive applications for use in the domestic market and is currently pursuing OEM business.

Sales and Distribution

Sales of the Company’s products are made directly to major OEMs and through a direct sales force and a worldwide network of independently-owned and company-owned distributors who sell engines, components and parts and provide service support to local OEMs, dealers and end-users. As of December 31, 1999 there were 27 distributors in North America operating a total of 173 authorized facilities and 82 distributors outside of North America operating 126 authorized facilities. The network of authorized service dealers, which is generally administered by these distributors, consists of over 2,400 dealers worldwide, of which approximately 2,100 are in North America. The Company has a controlling interest in three distributors and investments in five other distributors worldwide, of which five are located in North America and three overseas.

In support of its distribution system, the Company maintains a worldwide Parts Distribution Center in Canton, Ohio and overseas regional warehouses in the Netherlands and in Singapore. In addition, the Company’s sales and service activities are supported by four remanufacturing centers in the United States that provide remanufactured engines, components and parts. The Company also operates regional sales offices strategically located to support customers in all markets.

Orders for service parts can be filled by the Company’s Parts Distribution Center (“PDC”) in less than twenty four hours. Long-term blanket parts orders are also serviced by the PDC over periods covering one year or more. Certain orders such as military contracts or bus orders may be placed up to 12 months in advance of required delivery. On-highway OEM customers normally place firm orders for Series 60 engines only one month in advance of their next month’s production run. However, the Company typically negotiates annual volume targets with each OEM, and certain programs are used to provide incentives for the OEMs to purchase their targeted annual volume. Therefore, while firm orders are only received monthly, there are reasonably anticipated annual requirements that allow for production planning.

For the reasons stated above, the Company’s backlog of firm orders typically averages two to three months’ production, but the Company normally is aware of reasonably anticipated future orders well in advance of the placement of a firm order. At December 31, 1999 and 1998, the Company’s backlog of firm orders was approximately $388 million and $396 million, respectively.

The Company’s business is moderately seasonal, as its major OEM customers historically have two to four-week summer shutdowns of operations during the third quarter. The Company typically shuts down its own operations for one week each July, although a general shutdown of the Company’s operation did not occur in 1999. Additionally, the Company’s automotive operations typically shut down during the month of August. Consequently, the Company’s third quarter results reflect the effects of these shutdowns.

International

Significant portions of the Company’s products are sold in overseas markets, either directly as loose engines or indirectly in vehicles and equipment made by North American OEMs. Sales of automotive products are concentrated outside of North America. The Company has established foreign sales subsidiaries in Europe, Asia and Latin America that also function in a service and product support capacity. Parts warehousing operations are strategically located in the Netherlands and in Singapore, and work in conjunction with the Company’s Parts Distribution Center located in Canton, Ohio to maintain a high level of parts availability to overseas customers. The Company

has also entered into technical assistance and license agreements in strategic worldwide locations for the assembly and sale of products and components to meet the needs of local markets, and is pursuing similar arrangements in other locations. DDC also has indirect investment interests in Detroit Diesel distributorships in the Asia-Pacific region. The Company operates manufacturing and assembly facilities located in Cento, Italy and Curitiba, Brazil, respectively.

With the increase in global business activity, the Company is subject to risks of conducting business abroad, including currency exchange rate fluctuations, limits on repatriation of funds, compliance with foreign laws and other economic and political uncertainties that may threaten the Company’s operations or assets located in foreign countries. Changes in foreign currency exchange rates are generally reported as a component of stockholders’ equity. Changes in the value of the Italian Lira, the Singapore Dollar and the Brazilian Real will impact the Company’s translation adjustments in the future. Additionally, the Company has entered into transactions denominated in Deutsche Marks. Changes in the value of the Euro versus the United States dollar will affect the Company’s results of operations and financial position.

Summary information by geographic area is set forth in “Segment Information” in Note 8 of the Notes to the Consolidated Financial Statements.

Research and Development

The Company’s research and development efforts are intended to facilitate its ability to respond to market needs and the technological demands of the market. Total research and development expenditures were $105.8 million, $93.9 million and $97.5 million for 1999, 1998 and 1997, respectively. In addition, the Company conducts research and development that is funded by various government agency-sponsored projects. Emissions-related research and development activities, in compliance with the 1998 agreements with the U.S. Environmental Protection Agency and the California Air Resources Board, affected the levels of research and development spending during 1999.

Suppliers

The Company believes it has adequate sources for the supply of raw materials and components for its manufacturing needs. Suppliers are located primarily in North America, Latin America and Western Europe. In 1998, DDC implemented its Continuous Customer Value Improvement (“CCVI”) program. This program was aimed at strengthening its supplier relationships by working with those suppliers to achieve mutually beneficial supply chain improvements. This program has resulted in significant cost savings over the past two years while at the same time improving component quality.

DDC has developed a policy of concentrating its purchases for particular parts over a limited number of suppliers for some critical components. The Company believes that this policy contributes to quality control and cost control, as well as increasing the suppliers’ commitment to the Company. The Company purchases its forgings and casting from domestic, European and Latin American suppliers. Additionally, the Company relies upon, and expects to continue to rely upon, single source suppliers for the following critical components: electronic unit injectors from Diesel Technology Company (an affiliated company); camshafts and cylinder liners from Dana

Corporation; crankshafts from ThyssenKrupp Automotive; valves from Eaton Corporation; engine retarders from Jacobs Vehicle Systems; turbochargers from Honeywell-Garrett; fuel pumps from Robert Bosch, Inc. and electronic control modules from Motorola, Inc. While the Company believes it has adequate assurances of continued supply, the inability of a supplier to deliver or the loss of any of these suppliers could have an adverse effect on the Company’s business.

Competition

The heavy-duty diesel engine business is highly competitive. The Company competes based on price, quality, durability, fuel economy, emissions compliance, reliability and availability of replacement parts and service, as well as overall customer service. The distributor network plays a key competitive role in providing parts and service to end-users. The Company competes with independent diesel engine manufacturers as well as OEMs that manufacture engines for their own products. Certain of these OEMs are also customers of the Company. The Company’s principal competitors in international markets vary from country to country, with local manufacturers generally predominating each particular market. In North America, the Company’s principal competitors in each of its markets are Caterpillar Inc. and Cummins Engine Company, Inc. In its international markets, the Company also competes with several other manufacturers in Europe and Japan. The Company’s principal competitors are larger than the Company and have substantial resources. There can be no assurance that competitors will not be able to take actions, including developing new technology or products, or offering prolonged reduced pricing, which could adversely affect the Company.

Patents and Trademarks

The Company maintains, and has pending, various U.S. and foreign patents and patent licenses relating to its business, which it believes are appropriate to protect the Company’s interest in existing products, new inventions and product developments. VM also maintains various U.S. and foreign patents relating to its business. The Company does not believe any single patent is material to its business, nor would the expiration or invalidity of any patent have a material adverse effect on its business or its ability to compete. The Company is currently involved in a patent infringement lawsuit with one of its principal competitors. Additionally, a second patent infringement lawsuit with another one of the Company’s principle competitors, was decided in the Company’s favor during 1999. Refer to Item 3 for a discussion involving these matters.

The Company owns and maintains U.S. trademark registrations in all of its principal trademarks, including Detroit Diesel(R), the spinning arrows design, reliabilt(R) and Series 60(R). Registrations for its principal trademarks are also maintained in other countries where a significant volume of its products are sold and such registration is considered appropriate to protect the Company’s proprietary rights. All authorized distributors and remanufacturing centers are licensed to use these trademarks in the conduct of their businesses.

Employees

At December 31, 1999, the Company (including its distributor and remanufacturing subsidiaries) employed approximately 6,660 persons worldwide. Approximately 1,970 of the Company’s employees are represented by the International Union, United Automobile, Aerospace and Agricultural Implement Workers of America, Local 163 (“UAW”). UAW employees currently work under a six-year collective bargaining agreement that will expire on October 30, 2004.

Environmental Matters

Product Compliance. The Company’s engines are subject to extensive regulatory requirements. Specific emission standards are imposed by the U.S. Environmental Protection Agency (“EPA”) the California Air Resources Board (“CARB”) and foreign regulatory agencies. The Company’s ability to comply with current and future emission requirements is a critical element in maintaining and improving the Company’s position in the diesel engine marketplace and the inability to comply could have a significant impact on the Company’s future financial results. Substantial resources are included in the Company’s capital and operating budgets to comply with emission requirements.

The Clean Air Act establishes the U.S. regulatory framework for air quality and provides the EPA with authority for promulgating regulations and setting emission standards, including those applicable to engines used in heavy-duty, on-highway vehicles, as well as non-road vehicles and equipment. The Federal Clean Air Act allows only the State of California to set its own standards.

In 1998, the standard for nitrogen oxide (“NOx”) emissions from new engines used in heavy-duty trucks and urban buses was reduced from 5.0 to 4.0 grams per brake horsepower-hour (“g/bhp-hr”). Engines used in trucks and buses must also meet standards for particulate matter (“PM”), hydrocarbons (“HC”), carbon monoxide (“CO”) and smoke opacity. The current standards for on-highway diesel engines have been set to remain in effect through 2003. CARB standards are identical to EPA standards for 1998 through 2003.

The Company has a full line of on-highway engines of various horsepower ratings and configurations for trucks and buses that are divided into families. The Company has received EPA and CARB certification for all of these families for 2000.

In late 1997, the EPA and CARB advised the Company and other heavy-duty engine manufacturers that emissions control strategies employed may be in violation of the Clean Air Act. While the Company believes that the engine control strategies it used were in compliance with applicable laws and regulations, the Company engaged in discussions with the EPA, CARB and the U.S. Department of Justice to address the agency’s concerns. These discussions resulted in the negotiation of a Consent Decree with the United States and a settlement agreement with CARB which were signed on October 22, 1998. Similar agreements were negotiated and agreed to by other heavy-duty engine manufacturers. The Company believes that the settlements avoided the possibility of prolonged and complicated litigation between the parties and that the agreements are fair, reasonable and in the public interest. The Consent Decree was entered with the court on July 1, 1999.

Under the terms of the agreements, the Company agreed to: (1) limit certain engine software control strategies, (2) demonstrate emission performance for 1999 and later model year engines using specified supplemental test procedures in addition to existing certification procedures, (3) provide retrofit kits that can be used to reduce emissions when rebuilding existing engines, (4) assist in the development of and conduct in-use testing on in-service engines, (5) provide for certain low emission development programs, (6) meet certain emission limits earlier than would otherwise be required under existing regulations and (7) pay a civil penalty.

In addition to the diesel-fueled engine families noted above, the Company also has obtained 2000 EPA and CARB certification of spark-ignited Series 50G and Series 60G urban bus engine families which use natural gas for fuel. Natural gas engines have NOx and PM emissions which are lower than diesel-fueled engines and are an important alternative for customers seeking low emission engines, such as in the urban bus market.

Aside from the procedures required to obtain the new engine certification, the EPA has three principal means by which to verify compliance with its emission standards: (1) voluntary emission audit testing by the manufacturer, (2) Selective Enforcement Audits (“SEAs”) in which production engines are taken off the assembly line and tested in the presence of EPA compliance officers, and (3) in-use compliance testing in which the EPA removes engines from in-service vehicles and performs emission tests. To date, the EPA has relied on manufacturer audits and SEA testing. For several years, the Company has maintained an active program of voluntary emission audits and has reported test results to the agency. Successful completion of SEAs is important since upon failure of a SEA, the EPA has the authority to void the engine family certificate, require re-certification of the engine family and require the manufacturer to recall non-complying engines.

The EPA also has an emission defect-reporting program and may require a recall if defects are found in an emission-related component on 25 or more engines. CARB regulations require the Company to report failure of emission-related components through the monitoring of warranty claims. When the failure rate reaches a specified level (the greater of 25 component failures or one per cent of the engines built), reports are required to be filed with CARB. A recall may be triggered if failures are found on the greater of 50 engines or two percent of the engines built. The Company has submitted regular reports of warranty failures to CARB, and no recalls have been conducted as a result of these reports.

In 1993, the EPA issued a retrofit/rebuild rule for urban bus engines. Under the provisions of the rule, certain transit bus operators are required to use certified emission upgrade equipment when rebuilding their 1993 and earlier urban bus engines. In 1998, the Company certified equipment for 1993 and earlier 6V-92 mechanically controlled urban bus engines that will reduce PM emissions to below 0.10 g/bhp-hr. In 1999 equipment was certified for 1993 and earlier electronically controlled 6V-92 engines that also achieves 0.10 g/hp-hr of PM. This equipment is currently available for customer use.

The EPA also has promulgated regulations for engines used in non-road vehicles and equipment used in mining, agriculture, industrial, construction and other uses. The requirements phased in by engine power level categories beginning in 1996 with engines having rated

horsepower (“hp”) in the 175 to 750 range. Requirements for 100 to 175 hp and 50 to 100 hp took effect in 1997 and 1998, respectively. In 2000 requirements take effect for engines over 750 hp. The EPA’s regulations complement CARB regulations which went into effect in 1996 for 175 to 750 hp engines and which will apply to engines over 750 hp in 2000. More stringent Tier 2 requirements will begin to phase in by power category beginning in 2001. The Company has certified a complete line of non-road engines with various power ratings to meet EPA and CARB requirements for 2000. The EPA finalized emission regulations for propulsion and auxiliary engines over 50 hp used on commercial marine vessels in late 1999. These rules will phase in by displacement category beginning in 2004. The Company believes that many of the emission control technologies developed for non-road engines can be adapted for use on marine engines and that the Company will be well-positioned to offer a full line of marine engines that comply with the emission requirements.

Emission regulations for heavy-duty engines are prevalent throughout the world. In North America, Mexico and Canada have adopted U.S. emission requirements for on-highway engines. In 1999 the Company signed a Memorandum of Understanding with Environment Canada agreeing to market only U.S. certified non-road engines in Canada. Europe also has emission requirements for on-highway engines. Since the current regulations known as “Euro II” took effect in 1995, the Company has obtained certification authority approval for several Series 50 and Series 60 engine ratings. New and more stringent “Euro III” regulations have been adopted and will take effect in October 2000. Europe has also finalized regulations applicable to engines used in non-road mobile machinery. These regulations include two stages of standards which are being phased in by power level beginning in 1999. The standards and phase-in dates are generally compatible with the EPA’s current and proposed standards for non-road engines. The Company believes it is well positioned to meet these regulatory requirements for products that it sells in those markets.

The EPA also regulates noise emissions from heavy-duty vehicles. The Company works with vehicle OEMs to assure that vehicles with the Company’s engines comply with the noise requirements.

Facility Compliance. The Company believes that the facilities operated by it and its subsidiaries are in material compliance with applicable environmental statutes and regulations. Factory operations include machining, plating, painting, assembly and testing of diesel engines. An environmental engineering staff, under the direction of the Company’s manufacturing operations group, monitors air, water and solid waste discharge which result from factory operations as well as on-going remediation activities undertaken by the Company and prior operators of the facility. The Company operates, through subsidiaries, an engine manufacturing facility in Cento, Italy and an engine assembly facility in Curitiba, Brazil. The Company believes that these overseas facilities are in material compliance with applicable environmental laws and regulations.

The distributor facilities, in the ordinary course of business, are engaged in activities which involve steam and chemical cleaning of engines and component parts. These facilities also use and handle petroleum products for the fueling and lubrication of vehicles, vessels and equipment with diesel engines. Remanufacturing facilities are engaged in similar activities as well as assembling and testing new and remanufactured engines.

Facilities purchased or leased by the Company are typically subject to an environmental audit before commencing operations. Several of such facilities are or have been subject to remedial activities. Amounts expended in such remediation activities have been within anticipated budgets or covered under indemnity agreements from prior owner/operators and none have individually or in the aggregate been considered significant or material to the Company.

Item 2. Properties.

The Company’s world headquarters is located in Detroit, Michigan and its primary manufacturing facility is on adjoining premises located in the township of Redford, Michigan. The 129-acre site includes almost three million square feet of manufacturing and storage buildings, engineering laboratory and administrative offices. The Company leases this facility on a long-term basis with a right of first refusal and purchase option. The Company also operates a 575,000 square foot Parts Distribution Center in Canton, Ohio under a lease which expires in 2005. The Company and its remanufacturing subsidiary also operate a 300,000 square foot remanufacturing facility in Tooele, Utah. Its regional sales offices in North America and Europe are operated from leased facilities. The Company’s automotive operations are located in Cento, Italy and Curitiba, Brazil. The 19-acre site in Cento contains approximately 500,000 square feet of developed space for manufacturing, engineering and administrative offices. In 1997, the Company developed a 50,000 square foot automotive engine assembly facility in Curitiba. The Company believes its facilities are suitable for its current needs.

The Company-owned distributors either own or lease their facilities. The Company also subleases similar facilities in various locations to several independently owned distributors. Lease terms generally range from 5 to 15 years with renewal options. The Company’s remanufacturing business is conducted from four owned facilities located in Tooele, Utah; Emporia, Kansas; Cambridge, Ohio and Grand Rapids, Michigan.

Item 3. Legal Proceedings.

The Company is presently involved in certain claims and litigation arising in the ordinary course of its business, including claims relating to the use of and performance of the Company’s products. The Company does not believe that the resolution of any of these matters will have a material adverse effect on the Company’s results of operations or financial position.

James M. Wright, and five other individuals, filed a class action lawsuit against the Company and General Motors Corporation in the Superior Court of New Jersey, Camden County Law Division, on January 28, 1993, alleging that various two cycle engines, originally manufactured by either defendant were defective as modified in different ways by various third parties for use in yachts. Plaintiffs asserted claims on behalf of themselves and a proposed nationwide class for alleged breach of warranty, fraud, negligent misrepresentation and violation of the Magnuson-Moss Warranty Act, the New Jersey Consumer Fraud Act and the Uniform Commercial Code. The court denied class certification three times. In October 1998 defendants’ motions for summary judgment on the individual claims were granted. Two of the plaintiffs subsequently settled their individual claims, but four remaining plaintiffs again appealed the denial of class certification and dismissal of their individual claims. In March 2000, the parties

signed agreements settling the remaining individual claims, dismissing the appeal and releasing the defendant from all claims, to bring this protracted matter to a conclusion. While terms of the settlements are confidential, they will not have a material adverse impact on the financial position or results of operations of the Company.

Cummins Engine Company, Inc., a competitor of the Company, filed a lawsuit on June 6, 1997 in the U. S. District Court, Southern District of Indiana (Indianapolis Division) claiming that Detroit Diesel infringes a Cummins patent which discloses a method and device to generate information and software to calibrate electronic engine control modules. The complaint, as amended, seeks an injunction and unspecified damages. The Company has responded to the complaint denying infringement and has filed motions for summary judgment on various grounds, including non-infringement and invalidity, which are currently pending. The case is in the late discovery phase and a trial date is set for early 2001. The Company believes it has meritorious defenses to all claims and that the proceedings will not have a material adverse impact on the financial position or results of operations of the Company.

On July 1, 1999, the U.S. District Court for the District of Columbia formally entered the agreements negotiated by the Company and other engine manufacturers with the United States Department of Justice and the EPA to settle the lawsuits filed by the United States on October 22, 1998 for alleged violations of the Clean Air Act. The court order also finalized similar agreements with CARB. The agreements provide for the acceleration of lower NOx standards previously established by EPA and CARB for both on-highway and off-road engine applications and increase the stringency of testing procedures relative to emissions standards. The Company and the other settling manufacturers also agreed to modify electronic engine control strategies, provide for research and development to further reduce emissions and make specified settlement payments as previously reported. [Refer to Item One, Environmental Matters under the sub-heading Product Compliance for additional information.] The implementation of the agreements is underway.

Three other lawsuits have been filed by private litigants against the Company and other manufacturers that arise out of the same operative facts of the above case. In Environmental Law Foundation v. Cummins Engine Co., Inc. et al., which was filed on October 2, 1998 in the Supreme Court of California, San Francisco County, plaintiff alleged that the defendant heavy-duty vehicle and engine manufacturers violated state emissions laws and the Unfair Competition Law. Injunctive relief and restitution was sought on behalf of the public. On February 11, 1999, the court ruled that plaintiff failed to state valid claims and ordered the case dismissed. In Tri-State Express, Inc., et al. v. Cummins Engine Co., Inc. et al., filed on January 29, 1999 in the United States District Court for the District of Columbia, three trucking companies seek to represent a nationwide class of purchasers of heavy-duty diesel engines, and seek damages related to the same alleged violations of the Clean Air Act addressed in the EPA and CARB settlement agreements. Plaintiffs further claim that the sale of engines and trucks constituted breach of warranty and contract, unjust enrichment, violation of the Magnuson-Moss Warranty Act and fraud in violation of the Racketeer Influenced and Corrupt Organizations Act. Injunctive relief as well as compensatory and statutory damages are being sought. A motion to dismiss on behalf of all defendants is currently pending. Lastly, in California Dump Truck Owners Association et al. v. Cummins Engine Co., et al., filed on October 4, 1999 in the Superior Court of California, Los Angeles County (and later removed by defendants to the U.S. District Court

for the Central District of California), various purchasers of trucks equipped with heavy-duty engines allege violations of the Clean Air Act and California Health and Safety Code, breach of warranty, fraudulent misrepresentation, and unfair business practices. Unspecified damages are claimed. On January 10, 2000, the U.S. District Court granted the defendant’s motion for judgment on the pleadings. An appeal has been filed.

The Company believes it has meritorious defense to all of these claims and that these proceedings (including any appeals of the reported favorable decisions) will not have a material adverse impact on the financial position or results of operations of the Company.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion of Detroit Diesel Corporation’s (“Detroit Diesel”, “DDC” or the “Company”) historical results of operations and of its liquidity and capital resources should be read in conjunction with the Consolidated Financial Statements and related notes thereto.

Overview

Detroit Diesel Corporation achieved new records in several areas during 1999. Heavy-duty engine shipments exceeded 100,000 units, including over 91,900 Series 60 engines, both record levels. The Company sold nearly 1,600 DDC/MTU Series 2000 and MTU/DDC Series 4000 engines, more than double the number sold in the previous year. In addition, the Company’s PowerEvolution program, a program designed to transition customers from two-stroke to four-stroke products, was completed. Total revenues also achieved a new company high, totaling $2.4 billion, an increase of approximately 5% over 1998.

DDC’s earnings for 1999 also marked a new Company record. Net income was $49.2 million, an increase of 21% when compared to 1998 (excluding a special charge) resulting in basic earnings per share of $2.00. The increase in net income was driven by revenue growth combined with aggressive cost reduction activities, which resulted in a 0.4 percentage point increase in gross margin. Additionally, Detroit Diesel’s EBIT margin (earnings before interest and taxes divided by net revenues) grew to 3.6%, an increase of 0.3 percentage points compared to 1998 (excluding the special charge) and nearly a full percentage point increase over 1997.

During the fourth quarter of 1999, DDC’s board of directors approved a stock repurchase program which authorized the acquisition of up to 10% of the Company’s outstanding common stock over a period of two years. DDC repurchased approximately 4%, or 1.1 million shares through the end of 1999 at an average share price of $18 7/8.

Detroit Diesel’s balance sheet remained strong with total assets of $1.2 billion, essentially level with the prior year. Favorable cash flow, driven by improved operating performance, enabled the Company to reduce debt levels by approximately $27 million, to $78 million, at December 31, 1999. The debt reduction is especially significant considering the expenditures of $20 million to repurchase stock, $9 million in dividend payments and over $60 million in capital investment into the business. As a result, DDC’s debt to total capitalization ratio was 16.5% at the end of 1999 compared to 22.0% at the end of 1998.

1999 Compared to 1998

Net Revenues. Total 1999 net revenues of $2.4 billion were nearly 5% higher than 1998 net revenues of $2.3 billion. The increase in net revenues during 1999 reflects the overall strength of the North American on-highway heavy-duty truck market coupled with increased sales of the Company’s DDC/MTU Series 2000 and MTU/DDC Series 4000 engines. Series 60 engine unit sales totaled over 91,900 units versus 77,500 units in 1998, an increase of 14,400 units, or 19% over 1998 levels. Additionally, unit sales of the DDC/MTU Series 2000 and MTU/DDC Series 4000 engines more than doubled in 1999 as the Company completed its PowerEvolution program to transition customers from two-cycle to four-cycle products. Based on the strength of the increase in unit volumes, net revenues from four-cycle engine sales increased by $240 million and were somewhat offset by the decrease in two-cycle engine sales of $114 million. Net revenues from service parts and remanufactured products were consistent with 1998 levels despite the weakness experienced in the petroleum and mining sectors during most of the year.

Net revenues in the on-highway market, which represented approximately 65% of the Company’s total revenues, reflected the strength of the Company’s Series 60 products as well as the overall strength of the North American on-highway heavy-duty truck market. DDC’s market share ended 1999 at approximately 27.5%, down slightly from 28.5% in 1998, as overall market share was held down by capacity constraints early in the year. With increased production capacity in place during the second half of 1999, fourth quarter market share averaged approximately 29%, further reflecting the market strength of the Series 60 engine. Net revenues in the off-road market were $620 million or approximately 26% of the Company’s total revenues. The off-road market has shown improving fundamentals during the fourth quarter of 1999. Net revenues in the automotive market represent 9% of total revenues, up slightly from 1998, as net revenues increased 4% on a 1% increase in unit volume.

Gross Profit. Gross profit for 1999 was $559.8 million, or 23.7% of net revenues compared to $524.6 million, or 23.3% of net revenues for 1998, an increase of $35.2 million, or 7%. The improvement in gross margin is attributable to increased engine sales and the sales mix of the Company’s heavy-duty diesel engines and automotive products, combined with the Company’s cost reduction efforts under its Continuous Customer Value Improvement (“CCVI”) program.

Selling and Administrative Expenses. Selling and administrative expenses for 1999 were $368.0 million, or 15.6% of net revenues, compared to $355.6 million, or 15.8% of net revenues for 1998. While selling and administrative expenses increased $12.4 million over 1998 due to higher sales volumes, selling and administrative expenses as a percentage of sales decreased.

Research and Development Expenses. Research and development expenses were $105.8 million for 1999 compared to $93.9 million for 1998, an increase of $11.9 million. The increase reflects investments to develop new automotive products and Series 60 applications as well as emission-related activities.

Interest Expense. Interest expense was $7.9 million for 1999 compared to $11.8 million for 1998, a decrease of $3.9 million. The lower level of interest expense in 1999 is attributable to the Company’s strong cash flow during the year, combined with low interest rates on the Company’s revolving credit facility and low debt levels throughout the year.

Income Tax Expense. Income tax expense for 1999 was $28.9 million compared to $22.8 million in 1998. The Company’s annual effective tax rate for 1999 was approximately 37%. The increase in tax expense during 1999 reflects the Company’s higher level of earnings in 1999.

Net Income. Net income for 1999 was $49.2 million, compared to $28.0 million for 1998, an increase of $21.2 million. This amount represents the highest level of net income in Detroit Diesel’s history.

1998 Compared to 1997

Net Revenues. Record total 1998 net revenues of $2.3 billion were 4% higher than 1997 net revenues of $2.2 billion. The increase in net revenues during 1998 reflects the overall strength of the North American on-highway heavy-duty truck market coupled with increased sales of the Company’s DDC/MTU Series 2000 and MTU/DDC Series 4000 engines. Series 60 engine unit sales totaled over 77,500 units versus 65,700 units in 1997, an increase of 11,800 units, up 18% over 1997 levels. Additionally, unit sales of the DDC/MTU Series 2000 and MTU/DDC Series 4000 engines grew to over 660 units in 1998, an increase of over 500 units versus 1997. Also, revenues from the Company’s remanufacturing operations increased 14% versus the prior year. These increases were somewhat offset by the anticipated decline in two-stroke unit sales of 17% as the Company began implementation of its PowerEvolution program. Additionally, automotive sales decreased from record 1997 revenues reflecting the completion of certain supply contracts during 1998. Service parts sales during the year were consistent with 1997 levels.

Gross Profit. Gross profit for 1998 was $524.6 million, or 23.3% of net revenues, compared to $494.8 million, or 22.9% of net revenues for 1997, an increase of $29.8 million, or 6%. The increase in gross margin is attributable to increased engine sales and the sales mix of the Company’s heavy-duty diesel engines and automotive products, combined with the Company’s cost reduction efforts.

Selling and Administrative Expenses. Selling and administrative expenses for 1998 were $355.6 million, or 15.8% of net revenues, compared to $338.9 million, or 15.7% of net revenues for 1997, an increase of $16.7 million. The increase in selling and administrative expenses is attributable to higher sales volume for the Company’s products partially offset by the Company’s focus on controlling expenses through its cost reduction efforts.

Research and Development Expenses. Research and development expenses were $93.9 million for 1998 compared to $97.5 million for 1997, a decrease of $3.6 million. The decrease reflects lower expenditures for DDC/MTU Series 2000 and MTU/DDC Series 4000 engine development following these products’ introduction during 1997.

Interest Expense. Interest expense was $11.8 million for 1998 compared to $12.9 million for 1997, a decrease of $1.1 million. The lower level of interest expense in 1998 is attributable to lower interest rates, improved cash flow and the decrease in capital expenditures versus the prior year.

Special Charge. The Company recorded a special charge during 1998 of $12.5 million related to agreements with the U.S. Environmental Protection Agency and the California Air Resources Board to resolve the agencies’ concerns about the levels of oxides of nitrogen emissions from heavy-duty trucks under certain driving conditions. The special charge is payable in four annual installments, the first of which was paid in July 1999.

Income Tax Expense. Income tax expense for 1998 was $22.8 million compared to $15.6 million for 1997. The effective tax rate for 1998 was 44.9% and reflects the Company’s earnings

in 1998 including the effect of the special charge which is not tax deductible. Excluding the effect of this charge, the Company’s effective tax rate for 1998 would have been 36%.

Net Income. Net income for 1998 was $28.0 million, compared to $29.9 million for 1997, a decrease of $1.9 million. Excluding the special charge, net income would have been $40.5 million, or $1.64 per share, an increase of $10.6 million over 1998.

Liquidity and Capital Resources

During the three years ended December 31, 1999, Detroit Diesel funded its working capital, investments and capital expenditure requirements using cash flow from operations and bank borrowings under various revolving lines of credit and bank notes.

The Company has a $300 million, unsecured revolving credit agreement with a bank group, including The Chase Manhattan Bank (“Chase”), as participant and agent for the other participating banks, which expires in June of 2000. Borrowings under this agreement bear interest at LIBOR-based rates, prime-based rates and rates determined by competitive bidding among the participating banks. The Company had available credit under this agreement totaling approximately $294.7 million at December 31, 1999. Additionally, the Company has interest rate swap agreements, which extend through May 2000 and may be extended through May 2001, that effectively convert $50 million of its variable rate debt to a fixed rate of 6.05%.

The Company’s subsidiary, VM Motori S.p.A. (“VM”) has approximately $61 million in unsecured, short-term lines of credit with several banks. In addition VM has a long-term revolving credit arrangement with several banks, of which Chase is a participant, in the amount of approximately $26 million. At December 31, 1999, VM had available credit of approximately $41.3 million under short-term lines of credit.

The Company generated cash flows from operations of $ 117.9 million, $78.4 million and $54.9 million for 1999, 1998 and 1997, respectively, which reflects the Company’s net income, adjusted for non-cash items and changes in working capital.

Capital expenditures increased during 1999 to $60.8 million compared to $42.4 million in 1998 and $61.9 million in 1997. The majority of the increase in capital expenditures is attributed to the acquisition of a remanufacturing facility, which was previously leased, for approximately $11 million. Capital expenditures in 1999 were also used to expand and enhance production capacity of the Company’s Series 60, DDC/MTU Series 2000, MTU/DDC Series 4000 and automotive products, to upgrade and enhance engineering and information systems and upgrade facilities. The Company’s capital expenditure program for 2000 is approximately $64 million.

At December 31, 1999, the Company was contingently liable for letters of credit of approximately $12.8 million and guarantees to banks of approximately $14.6 million. The Company had commitments of approximately $11.0 million to complete various capital projects.

The Company is subject to risk of changes in foreign currency exchange rates due to operations located outside the United States. Changes in foreign currency exchange rates are generally reported as a component of stockholders’ equity. Changes in the value of the Italian Lira, the

Singapore Dollar and the Brazilian Real will impact the Company’s translation adjustments in the future. Additionally, the Company has recorded liabilities approximating 43.8 million Deutsche Marks as of December 31, 1999. Changes in the value of the Euro versus the United States dollar will effect the Company’s results of operation and financial position.

The Company’s primary revolving credit facility with Chase expires in June 2000 and the Company is in the process of evaluating potential new credit facilities. The Company believes that it will be able to satisfy on-going cash requirements (including capital expenditures for environmental compliance and other projects) for the next twelve months and thereafter, with cash flow from operations, supplemented as necessary, by borrowings under the current or new facility.

Year 2000

The “Year 2000 issue” is generally used to describe various problems that may result from the improper processing of dates related to the year 2000 and beyond by computers and other types of equipment, including embedded technology in production machinery and equipment. These problems are attributed to computer hardware and software that has been developed to use only two digits to identify the year in a date. This generally means that affected computer hardware and software will be unable to distinguish dates in the twenty-first century from similar dates in the twentieth century.

Costs to Address the Year 2000 Issue. The costs associated with Year 2000 compliance primarily consist of personnel expenses for those persons dedicated to the effort and for professional fees paid to third party providers for assistance and audit related activities. It is the Company’s policy to expense these costs as incurred. Additionally, the Company has invested in new and upgraded hardware and software to mitigate any potential Year 2000 issues. In these instances, the Company has capitalized allowable costs in accordance with its policies and procedures. Costs to complete the Year 2000 project were approximately $2.5 million. This cost does not include the Company’s potential share of Year 2000 costs that may be incurred by partnerships and joint ventures in which the Company participates but is not the operator.

Risks Presented by Year 2000 Issues. The Company did not experience any business interruption related to the Year 2000 issue. Management of the Company believes that there is a reasonably low level of risk that DDC will experience any significant collateral Year 2000 related problems that have not materialized to date. If any collateral problems, which are beyond the control of the Company, occur, there could be an interruption in, or failure of, the Company’s normal business activities.

Contingency Plans. While the Company had a Year 2000 contingency plan in place as part of its final Year 2000 plan, Detroit Diesel did not experience any Year 2000 related business interruptions that are known at this time. The Company would generally expect to manage business interruptions relating to Year 2000 issues that may still occur in a manner similar to other potential interruption issues encountered in the regular course of business. The Company intends to execute contingency plans as necessary as the year progresses. However, the contingency plans are expected to provide relief only for short periods, after which there could be an interruption in, or failure of, the Company’s normal business activities, that could have a

material adverse effect on the Company’s operations, liquidity and financial condition.

Segment Information

The Company has one reportable operating segment consistent with management’s approach of making internal operating decisions. All products produced by the Company are aggregated into one reportable operating segment since the nature of the products, production processes, distribution methods, and the Company’s principal customers are similar. The Company’s principal customers generally consist of original equipment manufacturers (“OEM’s”), while the ultimate customers are major fleet carriers and end users. (See Note 8 of Notes to Consolidated Financial Statements for additional information.)

Seasonality

The Company’s business is moderately seasonal, as its major OEM customers historically have two- to four-week summer shutdowns during the third quarter. The Company typically shuts down its own operation for one week each July although a general shutdown did not occur in 1999. Additionally, VM typically shuts down its operations during the month of August. Consequently, the Company’s third quarter results reflect the effects of these shutdowns.

Effects of Inflation

The Company believes that the relatively moderate inflation rate over the last few years has not had a significant impact on the Company’s revenues or profitability. The Company does not expect inflation to have any near-term material effect on the sales of its products, although there can be no assurance that such an effect will not occur in the future.

Foreign Operations

Approximately 29% of the Company’s 1999 net revenues were derived from sales made to purchasers in foreign countries. Included are the Company’s subsidiary locations in Cento, Italy and Curitiba, Brazil, which operate manufacturing facilities located in these countries. Because of these foreign factors, the Company’s business is subject to the risks of conducting business abroad, including currency exchange rate fluctuations, limits on repatriation of funds, compliance with foreign laws and other economic and political uncertainties. (See Note 8 of Notes to Consolidated Financial Statements.)

Introduction of the Euro

On January 1, 1999, eleven of the fifteen member states of the European Union (“Participating Countries”) established fixed conversion rates from their existing currencies (“Legacy Currencies”) to the Euro and have agreed to adopt the Euro as their common legal currency as of that same date. During a transition period from January 1, 1999 until January 1, 2002 the Legacy Currencies will remain legal tender and parties will have the option to pay in Euros or Legacy Currencies of Participating Countries. On January 1, 2002 Participating Countries are expected to issue Euro currency and withdraw all bills and coinage of Legacy Currencies by July 1, 2002.

The Company has committed resources to conduct risk assessments and to take corrective actions, where required, to ensure that the Company is prepared for the introduction of the Euro. The Company is in the process of reviewing areas such as operations, finance, treasury, legal, information management, purchasing and others, both in participating and non-participating European Union countries where the Company operates. Also, existing Legacy Currency accounting and business systems are in the process of review for Euro compliance. Compliance will be achieved primarily through upgraded systems, which were previously planned to be upgraded. Remaining systems will be modified to achieve compliance.

The Company does not currently expect to experience any significant operational disruptions or to incur any significant costs related to the Euro implementation that would materially affect the Company’s liquidity or capital resources. Euro conversion is expected to have little impact on prices and competition due to the fact that the Company’s product offerings and pricing strategies do not vary greatly among the Participating Countries. The conversion to the Euro is also not expected to impact material contracts of the Company. The Company’s overall costs of conversion to the Euro are not expected to be material.

Prospective Information

The Company anticipates reduced demand in the on-highway heavy-duty truck market during 2000 and expects the reduction in this market to have an effect on the Company’s operating performance during the next year. The effect that this reduced demand may have on the Company cannot be assessed at this time. The Company expects to increase its market share in the on-highway heavy-duty truck market, but the increase in market share is not expected to totally offset the overall effect of the expected market decline. Cost reduction programs such as CCVI are expected to continue to have a positive impact on operating margins and earnings and the Company believes the effect of these programs will help to offset the effect of the decline in the on-highway heavy-duty truck market. Additionally, increased DDC/MTU Series 2000 and MTU/DDC Series 4000 engine shipments in off-road markets are expected to positively impact the Company’s operations. The Company will also continue to pursue merger and acquisition opportunities that meet the Company’s criteria and strategic objectives.

New Accounting Pronouncements

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities.” This Statement requires companies to record derivatives on the balance sheet as assets and liabilities, measured at fair value. Gains or losses resulting from changes in the values of those derivatives would be accounted for depending on the use of the derivative and whether it qualifies for hedge accounting. This Statement is not expected to have a material impact on the Company’s consolidated financial statements. This Statement is effective for fiscal years beginning after June 15, 2000.

Cautionary Statement for purposes of “Safe Harbor” under the Private Securities
Litigation Reform Act of 1995

The Company may, from time to time, make forward-looking statements, including statements projecting, forecasting or estimating Company performance and industry trends. The achievement of the projections, forecasts or estimates contained in these statements is subject to certain risks and uncertainties, and actual results and events may differ materially from those projected, forecasted or estimated.

The applicable risks and uncertainties include general economic and industry conditions that affect all international businesses, as well as matters that are specific to the Company and the markets it serves. For example, the achievement of projections, forecasts or estimates contained in the Company’s forward-looking statements may be impacted by national and international economic conditions; compliance with U.S. and foreign treaties, laws and regulations; and the general risks associated with doing business abroad, such as currency exchange rate fluctuations, limits on repatriation of funds; political uncertainties and the Year 2000 issue.

Risks that are specific to the Company and its markets include compliance with increasingly stringent emissions controls standards applicable to diesel engines; the cyclical demand for engines, particularly in the on-highway heavy-duty truck market; competition in pricing and new product development from larger companies with substantial resources; the concentration of a substantial percentage of the Company’s sales with a few major OEM customers, the loss of, or change in demand from, any of which could have a material impact on the Company; increasing diversification in overseas markets and operations; labor relations at the Company and its customers and suppliers; and the Company’s single-source supply and just-in-time inventory strategies, which could adversely affect production if a single-source supplier is unable for any reason to meet the Company’s requirements.

Detroit Diesel Corporation

Notes to Consolidated Financial Statements

1. ORGANIZATION AND BUSINESS

Detroit Diesel Corporation (the “Company,” “Detroit Diesel” or “DDC”) is engaged in the design, manufacture, sale and service of heavy-duty diesel and alternative fuel engines, automotive diesel engines, and engine-related products. The Company offers a complete line of diesel engines from 22 to 11,000 horsepower for the on-highway, off-road, and automotive markets. Detroit Diesel services these markets directly and through a worldwide network of more than 2,700 authorized distributors and dealers. DDC is a QS-9000 certified company.

Detroit Diesel’s major shareholders are Penske Corporation (47.6%), a closely-held diversified transportation services company, Diesel Project Development, Inc. (“DPD”) (20.9%) and public stockholders (31.5%).

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. Affiliated companies in which the Company owns at least 20% of the voting securities are accounted for using the equity method. All significant intercompany transactions have been eliminated in consolidation.

Foreign Currency

The Company is subject to the risk of changes in foreign currency exchange rates due to operations located outside the United States. Changes in foreign currency exchange rates are generally reported as a component of stockholders’ equity. Changes in the value of the Italian Lira, Singapore Dollar and Brazilian Real will impact the Company’s translation adjustments in the future. Additionally, the Company has recorded liabilities approximating 43.8 million Deutsche Marks as of December 31, 1999.

Accounts and Notes Receivable

The accounts and notes receivable are net of an allowance of $4.7 million and $5.0 million at December 31, 1999 and 1998, respectively. The carrying value of accounts and notes receivable approximates fair value.

Inventories

Substantially all inventories are stated at the lower of cost or market, with cost determined by the first-in, first-out method.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Depreciation is computed using the straight-line method. The estimated service lives range from 5 to 35 years for buildings and improvements and 5 to 28 years for machinery, computer equipment, equipment and tooling, and leasehold improvements.

Intangible Assets

The Company amortizes the excess of cost over fair value of net assets acquired (Goodwill) on a straight-line basis over periods ranging from 5 to 40 years and other intangible assets over periods ranging from 3 to 30 years. Intangible assets are reported net of accumulated amortization of $34.1 million and $26.4 million at December 31, 1999 and 1998, respectively. The Company periodically evaluates the carrying value of its intangible assets for impairment. This evaluation is based principally on the projected, undiscounted cash flows generated by the related tangible assets.

Income Taxes

Deferred tax assets and liabilities reflect the impact of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

Special Charge

The Company recorded a special charge during 1998 of $12.5 million related to agreements with the U.S. Environmental Protection Agency (“EPA”), the California Air Resources Board (“CARB”) and major heavy-duty engine manufacturers. The special charge is payable in four annual installments, the first of which was paid in July 1999.

Product Coverage Programs

Estimated costs of product coverage, including warranty, are charged to operations at the time the Company sells its products. Such costs were $127.0 million, $113.8 million, and $103.3 million in 1999, 1998 and 1997, respectively. In addition to amounts included in accrued expenses (Note 10), other liabilities includes $71.8 million and $70.5 million at December 31, 1999 and 1998, respectively, for these programs.

Derivative Financial Instruments

The Company may enter into derivative financial instruments to manage its exposure to fluctuations in interest and currency exchange rates. Derivative financial instruments are not used for speculative or investment purposes. The Company is exposed to market risks arising from changes in interest and foreign currency exchange rates. Interest rate swap agreements that effectively change the interest rate characteristics of existing debt are accounted for as an adjustment to interest expense.

Long Lived Assets

The Company evaluates the carrying value of its long lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may be impaired.

Research and Development

Research and development expenditures are charged to operations as incurred.

Post-retirement and Post-employment Benefits Other than Pensions

The Company records post-retirement healthcare benefit costs during the period employees provide service to the Company. The Company funds its post-retirement healthcare benefit obligation as benefits are paid. The Company amortizes the initial accumulated benefit obligation over a 20 year period (Note 15).

The Company provides other post-employment benefits to its employees. Post-employment benefits offered include disability benefits, supplemental unemployment benefits, workers’ compensation benefits, and continuation of health care benefits and life insurance coverage. The costs of providing these other post-employment benefits are not significant.

Use of Estimates

The preparation of the Company’s financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts of assets and liabilities reported therein. Actual results reported in future periods may differ from these estimates.

Reclassifications

Certain reclassifications have been made to prior year amounts to conform with the classifications used in 1999.

New Accounting Pronouncement

In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standard No. 133, “Accounting for Derivative Instruments and Hedging Activities.” This Statement requires companies to record derivatives on the balance sheet as assets and liabilities, measured at fair value. Gains or losses resulting from changes in the values of those derivatives would be accounted for depending on the use of the derivative and whether it qualifies for hedge accounting. This Statement is not expected to have a material impact on the Company’s consolidated financial statements. This Statement is effective for fiscal years beginning after June 15, 2000.

3. NET INCOME PER SHARE

Basic net income per share represents net income available to common stockholders divided by the weighted average number of common shares outstanding during the period. For the years ended December 31, 1999, 1998 and 1997 the weighted average number of shares outstanding were 24,598,000 shares, 24,702,000 shares and 24,698,000 shares, respectively.

Diluted net income per share represents net income available to common stockholders divided by the weighted average number of common shares outstanding plus the weighted average dilutive effect of the Company’s incentive stock options outstanding (See Note 16) during the period calculated using the treasury stock method. The dilutive effect of the Company’s incentive stock options for the years ended December 31, 1999, 1998 and 1997 were 76,000 shares, 52,000 shares and 81,000 shares, respectively.

Weighted average shares outstanding for the year ended December 31, 1999 were affected by a common stock repurchase program initiated during the fourth quarter (Note 4).

4. COMMON STOCK REPURCHASE PROGRAM

In November 1999, the Board of Directors approved a plan to repurchase up to 10% of the outstanding common stock of the Company either through open market purchases or negotiated transactions.

The Company has up to two years to complete repurchases under this discretionary program. During 1999, 1,090,000 shares were repurchased at a cost of approximately $20.6 million, which represented approximately 4% of the outstanding common stock of the Company.

8. SEGMENT INFORMATION

Detroit Diesel has one reportable operating segment, consistent with management’s approach of making internal operating decisions. All products produced by the Company are aggregated into one reportable operating segment, since the nature of the products, production processes, distribution methods, and the Company’s principal customers are similar. The Company’s principal customers generally consist of original equipment manufacturers (OEM’s), while the ultimate customers are major fleet carriers and end users. The Company offers a complete line of diesel engines and related products and sells its products principally in the on-highway (truck and bus), off-road (marine, military, power generation and construction and industrial) and automotive markets.

The on-highway heavy-duty truck market is the Company’s largest market and is served primarily by DDC’s four-stroke products. The on-highway market comprised approximately 65%, 60% and 56% of the Company’s net revenues for 1999, 1998 and 1997, respectively. The Company’s largest customer is DaimlerChrysler, which comprised approximately 35%, 32% and 30% of the Company’s net revenues in 1999, 1998 and 1997, respectively. Additionally, within

the on-highway heavy-duty truck market, the Company’s largest OEM customers are Freightliner Corporation, Navistar International Transportation Corp., Volvo GM Heavy Truck Corporation and PACCAR Inc., from which approximately 49%, 38% and 39% of the Company’s net revenues in 1999, 1998 and 1997, respectively, were derived.

The following data include revenues based on the geographic region from which the sale was generated and long lived assets based on physical location.

The Company and its subsidiaries have $27.4 million and $38.3 million in debt under certain short term lines of credit and bank loan agreements at December 31, 1999 and 1998, respectively, of which approximately $19.8 million is denominated in Italian Lira at December 31, 1999. The weighted average interest rate at December 31, 1999 was 4.4%. The amount available for borrowing under these agreements was approximately $105.8 million at December 31, 1999 and $93 million at December 31, 1998.

The Company has a $300 million, unsecured variable rate credit facility which expires in June 2000. This facility has several covenants which require the maintenance of a certain level of net worth, restrict the Company’s ability to incur additional debt and require maintenance of minimum interest coverage and leverage ratios. The Company expects to enter into a new credit facility during the first half of 2000. At December 31, 1999, the Company had approximately $294.7 million available under its revolving lines of credit. At December 31, 1999, approximately $30.2 million of long-term debt is denominated in Italian Lira. The carrying value of long-term debt approximates fair value.

The Company has interest rate swap agreements, which extend through May 2000 and may be extended through May 2001, that effectively converts $50 million of its variable rate debt to a fixed rate of 6.05%.

In 1997, the Company reassessed its deferred taxes associated with tax losses which were acquired with the purchase of VM Motori S.p.A. (“VM”) in 1995. These loss carryforwards were realized by VM during 1997. The review resulted in a reduction in deferred tax liabilities and goodwill of approximately $6.3 million.

The Company has not recorded deferred taxes on the undistributed earnings of foreign subsidiaries which are deemed to be indefinitely reinvested. Such undistributed earnings aggregate to approximately $27.3 million, $22.0 million and $17.9 million at December 31, 1999, 1998 and 1997, respectively.

12. FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company has the following derivative financial instruments at December 31:


(In millions)
	Notional		Carrying		Fair

1999




Interest rate swap agreements	$	50.0	$	—	$	—




1998




Interest rate swap agreements	$	50.0	$	—	$	(1.2	)

The fair value of the interest rate swap agreements was determined using prevailing spot rates at December 31, 1999 and 1998, and discounted as applicable.

13. COMMITMENTS, CONTINGENCIES AND CONCENTRATIONS

Several claims, suits and complaints arising in the ordinary course of business have been threatened or are pending against the Company. In the opinion of management, all such matters are adequately covered by insurance or indemnification or, if not so covered, there are meritorious defenses to all such claims, or they are of such kind, or involve such amounts, as would not have a materially adverse effect on the financial position or results of operations of the Company if disposed of unfavorably.

Facilities purchased or leased since the Company began operations are typically subject to an environmental audit before commencing operations. Several of such facilities have been subject to remediation activities due to non-compliance with applicable regulations. Amounts expended in such remediation activities have generally been insignificant or have been covered under indemnity agreements from prior owner/operators and none have individually or in the aggregate been considered material to the Company’s financial position or results of operations.

At December 31, 1999, the Company was contingently liable for letters of credit of $12.8 million and bank guarantees of $14.6 million. The Company had commitments of approximately $11.0 million to complete various capital projects.

The Company leases its United States production facility and administrative offices, certain distributor and remanufacturing facilities, certain production machinery, equipment and tooling, its parts distribution center and various transportation and office equipment. Certain leased properties are subleased to distributors. The leases have terms of varying lengths and substantially all are accounted for as operating leases. Certain of the leases contain several covenants which require the maintenance of a certain level of net worth, restrict the Company’s ability to incur additional debt and require the maintenance of minimum interest coverage and leverage ratios.

In accordance with the terms of the 1998 EPA and CARB settlement agreements, the Company has committed to advanced research and development activities over the next four years to generate further emission reductions. These expenditures will be made as a part of the Company’s continuing environmental research and development efforts.

The Company believes it has adequate sources for the supply of raw materials and components for its manufacturing requirements. The Company’s suppliers are located primarily in North America and Western Europe. The Company has a policy of strengthening its supplier relationships by concentrating its purchases for particular parts over a limited number of suppliers in order to maintain quality and cost control and to increase the suppliers’ commitment to the Company. The Company relies upon, and expects to continue to rely upon, several single source suppliers for critical components.

Future minimum payments under non-cancelable operating leases and other commitments, including related party leases, at December 31, 1999 are: $20.7 million in 2000; $16.7 million in 2001; $12.7 million in 2002; $10.1 million in 2003; $9.5 million in 2004 and $46.5 million in the year 2005 and thereafter.

The Company’s primary production facility located in Michigan employs approximately 2,000 employees represented by the International Union, United Automobile, Aerospace and Agricultural Implement Workers of America, Local 163 under a six-year collective bargaining agreement which expires on October 30, 2004.

14. PENSION AND OTHER EMPLOYEE BENEFITS

The Company has defined benefit pension plans covering the majority of its employees. Benefits for salaried employees are provided under an account balance type of defined benefit plan, under which the benefit is determined primarily on the basis of annual contributions, with a minimum benefit related to an employee’s highest average annual compensation determined over a 60-month period selected out of the 120-month period immediately prior to retirement. Benefits for eligible hourly employees are provided primarily on the basis of a monthly amount for each year of credited service. The types of assets held by the plans include equity, fixed income and real estate funds. It is the Company’s policy to make contributions to these plans to meet funding levels required by the Employee Retirement Income Security Act of 1974.

The following tables set forth the plans’ changes in benefit obligations, changes in plan assets, amount recognized in the Company’s balance sheet, assumptions, and components of net periodic benefit cost at December 31:

The Company also sponsors other defined contribution plans, including deferred savings plans, covering a majority of its domestic employees. Employee contributions are based on a percentage of payroll.

Certain plans require the Company to make matching contributions based on a percentage of employee contributions. They also provide for the employer to make discretionary contributions. Where contributions are made, amounts are based on a percentage of payroll for eligible employees. Contributions to these plans in 1999, 1998 and 1997 totaled $8.1 million, $7.6 million and $6.8 million, respectively.

The Company maintains profit sharing programs covering all of its domestic employees and cash and stock bonus incentive plans covering certain senior officers and other eligible employees. Contributions to these programs are based on income before interest and taxes or earnings before taxes.

The Company’s Italian subsidiary, VM, accrues employee termination indemnities in accordance with local civil and labor laws based upon each employee’s length of service, employment category and remuneration. There are no vesting periods or funding requirements associated with this liability and benefits are payable immediately upon separation. The liability is adjusted annually by a cost-of-living index provided by the Italian government. The cost of providing these benefits during 1999, 1998 and 1997 approximated $1.8 million, $1.8 million and $1.9 million, respectively. The termination liability recorded in the balance sheet is the amount to which the employee would be entitled upon separation from the Company.

15. POST-RETIREMENT BENEFITS OTHER THAN PENSIONS

The Company provides certain health care benefits for retired employees. Eligibility is based on years of service and requires employees to remain employed until retirement age. These benefits are either self-insured or are provided through health insurance plans.

The following tables set forth the plans’ changes in benefit obligations, changes in plan assets, amount recognized in the Company’s balance sheet, and components of net periodic benefit cost at December 31:

Change in benefit obligation:


(In millions)	December 31,

	1999			1998

Amortization of prior service costs		.1		.1		.1




Recognized actuarial loss		.8		.4		.1

Net periodic benefit cost	$	12.3	$	11.4	$	10.9

For measurement purposes, a 6.0% annual rate of increase in the per capita cost of covered health care benefits was assumed for all years. The discount rate used to calculate the benefit obligation was 7.75% and 7.0% for the years ended December 31, 1999 and 1998, respectively. The health care cost trend rate assumption has an effect on the amount reported. Changing the assumed health care cost trends by one percentage point in each year would change the accumulated post-retirement benefit obligation as of December 31, 1999 by approximately $0.6 million, but net periodic post-retirement benefit cost would not be affected for 2000, consistent with 1999. The estimate incorporates defined dollar limits on Company costs for post-retirement benefits and is supplemented by amounts contributed by the Company and the UAW to a fund that can be used to reimburse costs which exceed the plan coverage limits.

16. STOCK INCENTIVE PLAN

The Company has stock incentive plans, adopted in 1993 and 1998, and has reserved shares of common stock for issuance pursuant to those plans. All shares under the 1993 plan have been issued and the entire balance of the 1.2 million options reserved under the 1998 plan remain unissued. Under the plans, the Company can grant restricted or unrestricted stock, stock appreciation rights, non-qualified options and options qualifying as incentive stock options under the Internal Revenue Code of 1986, as amended.

The term of an option cannot exceed 10 years from the grant date and the option price may not be less than market value at the date of grant. The Company accounts for stock option grants in accordance with APB Opinion No. 25 and related interpretations. No compensation cost has been recognized for stock option grants since the options have exercise prices of not less than the market value of the Company’s common stock at the date of the grant. If compensation cost for stock option grants had been determined based on the fair value at the grant dates for 1999, 1998, and 1997 consistent with Statement of Financial Accounting Standards No. 123 (“SFAS No. 123”), the Company’s net income and net income per share would not be materially different than the amounts presented in the accompanying Statements of Income. Under SFAS No. 123, the fair value of each option is estimated on the date of the grant using an option pricing model with assumptions for dividend yield, volatility, risk-free interest and expected life. The Company estimated the fair value of the options granted in 1998 and 1997 according to the following assumptions: dividend yield of zero, expected price volatility of 32%, risk-free interest rates of 6% and expected lives of five years.

Options exercisable as of December 31 were 572,779 shares in 1999, 460,779 shares in 1998 and 362,750 shares in 1997 at a weighted-average option price of $20.40, $20.15 and $20.44, respectively. The option shares outstanding at December 31, 1999 have a range of exercise prices between $17.00 and $23.94, a weighted average exercise price of $20.44 and a weighted average remaining life of 6.1 years.

A summary of options granted under the Company’s stock incentive plans as of December 31 and changes during the years then ended is presented below:

Report of Management

The consolidated financial statements of Detroit Diesel Corporation have been prepared by management and have been audited by Detroit Diesel Corporation’s independent auditors, Deloitte & Touche LLP. Management is responsible for the consolidated financial statements, which have been prepared in conformity with generally accepted accounting principles and include amounts based on management’s judgments.

Management is also responsible for maintaining internal accounting control systems designed to provide reasonable assurance, at appropriate cost, that assets are recorded in accordance with established policies and procedures. Detroit Diesel Corporation’s systems are under continuing review and are supported by, among other things, business conduct and other written guidelines, an internal audit function and the selection and training of qualified personnel.

The Board of Directors is responsible for the Company’s financial and accounting policies, practices and reports. Its Audit Committee, comprised of outside directors, meets regularly with the independent auditors, representatives of management and the internal auditors to discuss and make inquiries into their activities. Both the independent auditors and the internal auditors have free access to the Audit Committee, with and without management representatives in attendance, to discuss the results of the audit, the adequacy of internal accounting controls, and the quality of the financial reporting.

It is management’s conclusion that the system of internal accounting controls at December 31, 1999 provides reasonable assurance that the books and records reflect the transactions of the Company and that the Company has complied with its established policies and procedures.

Independent Auditors’ Report

To the Board of Directors and Shareholders of
Detroit Diesel Corporation

We have audited the accompanying consolidated balance sheets of Detroit Diesel Corporation and subsidiaries (the “Company”) as of December 31, 1999 and 1998 and the related consolidated statements of income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 1999. 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. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 1999 and 1998 and the results of its operations and its cash flows for each of the three years in the period ended December 31, 1999, in conformity with generally accepted accounting principles.
