MARKETING AND DISTRIBUTION --------------------------

CTS sales engineers and manufacturers'independent manufacturers’ representatives sell products from both electronic componentsthe Components and electronic assembliesSensors business segment and the EMS business segment to OEMs. CTS maintains sales offices in China, Hong Kong, Japan, South Korea, Scotland, Singapore, Taiwan and the United States. Approximately 63%65% of 2001 total2002 net sales werewas attributable to coverage by CTS sales engineers.

CTS sales engineers generally service the largest customers with application specific products. The engineers work closely with major customers in designing and developing products to meet specific customer requirements.

CTS utilizes the services of independent manufacturers'manufacturers’ representatives and distributors in the United States and other countries for customers not serviced directly by CTS sales engineers for both of its business segments. Independent manufacturers'manufacturers’ representatives receive commissions from CTS. During 2001, approximately 33%2002, 32% of net sales werewas attributable to coverage by independent manufacturers'manufacturers’ representatives. Additionally, independentCTS also uses distributors for customers in its Components and Sensors business segment. Independent distributors purchase component and sensor products from CTS for resale to customers. In 2001,2002, independent distributors and/or dealers accounted for approximately 4%3% of net sales.

RAW MATERIALS -------------

CTS utilizes a wide variety of raw materials and purchased parts in its manufacturing processes. Shown belowThe following are the most significant raw materials segregatedand purchased parts, identified by business segment: Electronic assemblies: steel, copper, precious metals, resistive and conductive inks, passive electronic components and semiconductors and ceramic materials. Electronic components: steel, copper, brass, aluminum, precious metals, resistive and conductive inks, piezoceramics, passive electronic components and semiconductors, ceramic materials, synthetic quartz and molding compounds.

          Components
and Sensors:Copper, brass, precious metals, resistive and conductive inks, piezoceramics, passive electronic components and semiconductors, integrated circuits, ceramic materials, plastic and molding compounds, printed circuit boards, quartz blanks and crystals.

EMS:Power supplies and converters, prefabricated steel, printed circuit boards, passive electronics components and semiconductors, integrated circuits, connectors, cables and modules.

These raw materials are purchased from several vendors, and except for certain semiconductors, CTS does not believe it is dependent upon one or a limited number of vendors. Although CTS purchases all of its semiconductors from a limited number of vendors, alternative sources are available. In 2001,2002, substantially all of these materials were available in adequate quantities to meet CTS'CTS’ production demands. 5

CTS does not currently anticipate any raw material shortages which would slow production. However, the lead times between the placement of orders for certain raw materials and purchased parts and actual delivery to CTS may vary, and occasionallyvary. Occasionally CTS might require CTSneed to order raw materials in greater quantities and at higher prices than optimal to compensate for the variability of lead times for delivery.

Precious metal prices may have a significant effect on the cost and selling price of many CTS products, particularly some ceramic filters, sensors, resistor networks switches, backpanels and integrated interconnect systems. At December 31, 2001, CTS had forward contracts in place to mitigate the risk of market price fluctuations of palladium, one of the precious metals used in its manufacturing process. See also Note A, "Summary of Significant Accounting Policies - Financial Instruments," appearing in the financial statements as noted in the Index appearing under Item 14 (a) (1) and (2). switches.

WORKING CAPITAL ---------------

Working capital requirements are generally dependent on the overall level of business activities. During 2001,2002, consolidated working capital decreased tofrom $46.8 million to $17.8 million. Lower inventory and accounts receivable levels primarily due tocaused by reduced sales volumes contributed $31.6 million of the decrease to working capital. Other significant components of the change in accounts receivable and inventories and the increase inworking capital include lower current maturitiesdeferred tax assets of long-term debt. These decreases$15.5 million which were partially offset by decreases in accountslower trade payable and other accruals and increases in the current deferred tax asset.of $19.7 million. Changes in CTS'CTS’ cash position during 20012002 are shown in the "Consolidated Statement“Consolidated Statements of Cash Flows"Flows” as noted in the Index appearing under Item 1415 (a) (1) and (2).

CTS does not usually buy inventories or manufacture products without actual or reasonably anticipated customer orders, except for some standard, off-the-shelf distributor products. CTS is not generally required to carry significant amounts of inventory in anticipation of rapid delivery requirements because most customer orders are custom built. CTS has "just-in-time"“just-in-time” arrangements with certain major customers and vendors to efficiently meet delivery requirements.

CTS carries raw materials, including certain semiconductors, work-in-process and finished goods inventories which are unique to particular customers. In the event of reductions or cancellations of orders, some inventories may not be useable or returnable to vendors for credit. CTS generally imposes charges for the reduction or cancellation of orders by customers, and these charges are usually sufficient to cover a significant portion of the financial exposure of CTS for inventories which are unique to a customer. CTS does not customarily grant special return or payment privileges to customers. CTS'CTS’ working capital requirements and businesses are generally neither cyclical nor seasonal.

PATENTS, TRADEMARKS AND LICENSES --------------------------------

CTS maintains a program of obtaining and protecting U.S. and non-U.S. patents and trademarks. CTS believes its success is not materially dependent on the existence or duration of any patent, group of 6 patents or trademarks. CTS haswas issued 29 new U.S. patents in 2002 and currently holds in excess of 350360 U.S. patents with hundreds of non-U.S. counterpart patents.

CTS licenses the right to manufacture several electronic products to companies in the United States and non-U.S. countries. In 2001,2002, license and royalty income was less than 1% of net sales. CTS believes its success is not materially dependent upon any licensing arrangement where CTS is either the licensor or licensee.

MAJOR CUSTOMERS --------------- CTS'

CTS’ 15 largest customers represented 73% of net sales in 2002 and 75% of net sales in 2001 and 2000, and 71%2000. Sales to Hewlett-Packard Company (Hewlett-Packard), which acquired Compaq Computer Corporation (Compaq) in May 2002, amounted to 33% of net sales in 1999.2002. Sales to Compaq Computer Corporation (Compaq) amounted towere 28% of net sales in 2001, and 21% of net sales in 2000 and 11%2000. Sales to Motorola, Inc. (Motorola) accounted for 12% of net sales in 1999. Sales to Motorola, Inc., (Motorola) accounted for2002, 17% of net sales in 2001 and 21% of net sales in 20002000.

EMS business segment revenues from Compaq represent $160.6were $160.2 million, or 61%76%, $177.9and $177.6 million, or 54%, and $72.0 million, or 42%74%, of the segment'ssegment’s revenue for the year ended December 31, 2001, 2000 and 1999, respectively, and from Motorola represented $50.5, or 19%, and $65.8, or 20%, for the yearyears ended December 31, 2001 and 2000, respectively.

We expect to continue to depend on sales to our major customers. Some of our customers are increasingly outsourcing their purchasing activities, with the result that a greater emphasis is being placed on cost while maintaining an emphasis on quality. Since it is difficult to replace lost business on a timely basis, it is likely that our operating results would be adversely affected if one or more of our major customers were to cancel, delay or reduce a large amount of orders with us in the future. If one or more of our customers were to become insolvent or otherwise unable to pay for our products, our operating results, and financial condition and cash flows could be adversely affected.

ORDER BACKLOG -------------

Order backlog may not provide an accurate indication of present or future revenue levels for CTS. For many electronic components and electronic assemblies,sensors and EMS products, the period between receipt of orders and expected delivery is relatively short. Additionally, large orders from major customers may include backlog covering an extended period of time. Production scheduling and delivery for these orders could be changed or canceled by the customer on relatively short notice. 7

The following table shows order backlog by segment and in total as of February 24, 2002January 26, 2003 and February 25, 2001. February 24, 2002 February 25, 2001 ----------------- ----------------- ($ in millions) Electronic Components $52 $120 Electronic Assemblies $18 $ 30 Total $70 $150 This decrease is largely the result of softening market conditions andJanuary 27, 2002.

Backlog decreased slightly compared to amounts from one year ago. Many customers are still displaying a conservative ordering pattern, by many customers, including short-term and small quantity orders. Order backlog at the end of February 2002January 2003 will generally be filled during the 20022003 fiscal year.

GOVERNMENT CONTRACTS --------------------

CTS estimates underless than 1% of its net sales are associated with purchases by the government.

COMPETITION -----------

In the electronic componentsComponents and Sensors business segment, CTS competes with many U.S. and non-U.S. manufacturers principally on the basis of product features, price, technology, quality, reliability, delivery and service. Most CTS product lines encounter significant global competition. The number of significant competitors varies from product line to product line. No one competitor competes with CTS in every product line, but many competitors are larger and more diversified than CTS. Some competitors are divisions or affiliates of CTS'CTS’ customers.

In the electronic assembliesEMS segment, CTS competes with a number of well-established U.S. and non-U.S. manufacturers on the basis of product features, price, technology, quality, reliability, delivery and service in the markets in which we participate. Most CTS product lines

6

encounter significant global competition. Some of our competitors have greater manufacturing and financial resources. However, we generally do not pursue extremely high volume, highly price sensitive business, as do some of our major competitors. Some competitors are divisions or affiliates of CTS'CTS’ customers.

In both the electronic componentsComponents and electronic assembliesSensors and EMS business segments, some customers have reduced or plan to reduce their number of suppliers, while increasing the volume of their purchases. Most customers are demanding higher quality, reliability and delivery standards from CTS as well as competitors. These trends create opportunities for CTS, but also increase the risk of loss of business to competitors. CTS is subject to competitive risks which are the nature of the electronics industry including short product life cycles and technical obsolescence.

CTS believes it competes most successfully in custom products manufactured to meet specific applications of major OEMs. 8

NON-U.S. REVENUES AND RISKS ---------------------------

In 2001, 57%2002, 56% of net sales to external customers originated from non-U.S. operations compared to 57% in 2001 and 52% in 2000 and 53% in 1999.2000. At December 31, 2001,2002, approximately 41%39% of total CTS assets were located at non-U.S. operations compared to 36%41% of total CTS assets at the end of 2000.2001. A substantial portion of these assets, other than cash and equivalents, cannot readily be liquidated. CTS believes the business risks to its non-U.S. operations, though substantial, are normal risks for non-U.S. businesses. These risks include currency controls and changes in currency exchange rates, longer collection cycles, political and transportation risks, economic downturns and inflation, government regulations and expropriation. CTS'CTS’ non-U.S. manufacturing facilities are located in Canada, China, Mexico, Scotland, Singapore and Taiwan.

Net sales to external customers originating from non-U.S. operations for the electronic componentsComponents and Sensors business segment were $179.4$153.8 million in 2002, compared to $210.4 million in 2001 compared to $305.4 in 2000, and $280.4$341.2 million in 1999.2000. Net sales to external customers originating from non-U.S. operations for the electronic assembliesEMS business segment were $151.6$104.0 million in 2002, compared to $120.6 million in 2001 compared to $146.6 in 2000, and $78.0$110.7 million in 1999.2000. Additional information about net sales to external customers, operating earnings and total assets by segment, and net sales to external customers and long-lived assets by geographic area, is contained in Note K, "BusinessI, “Business Segments," appearing in the financial statements as noted in the Index appearing under Item 14(a)15 (a) (1) and (2).

RESEARCH AND DEVELOPMENT ACTIVITIES -----------------------------------

In 2002, 2001 2000 and 1999,2000, CTS spent $24.1 million, $32.8 $32.6million and $25.3$32.6 million, respectively, for research and development. The reduction in 2002 reflects savings due to organizational consolidation of certain products. Significant ongoing research and development activities continue in our Components and Sensors business segment to support current product and process enhancements, expanded applications and new product development. Research and development expenditures in the EMS business segment are typically much lower.

CTS believes a strong commitment to research and development is required for future growth. Most CTS research and development activities relate to developing new products and technologies, improving product flow and adding product value to meet the current and future needs of its customers. CTS employs approximately 650530 engineers and technicians who are specifically assigned to the development of new materials, new processes and innovative products. CTS provides its customers with full systems support to ensure quality and reliability through all phases of design, launch and manufacturing to meet or exceed customer requirements. Many such research and development activities are for the benefit of one or a limited number of customers or potential customers. CTS expenses all research and development costs as incurred.

EMPLOYEES ---------

CTS employed 5,8375,313 people at December 31, 2001,2002, and 69%73% of these people were employed outside the United States. Approximately 270260 CTS employees at one location in the United States were covered by collective bargaining agreements as of December 31, 2001.2002. One agreement will expire in 20032005 and the other will expire in 2005.2008. CTS employed 9,0605,837 people at December 31, 2000. As discussed in Note B, "Restructuring and Impairment Charges," appearing in the financial statements as noted in the Index appearing under Item 14 (a) (1) and (2), the Company expects further reductions in its workforce in 2002, as it completes its restructuring actions initiated in 2001. 9

Item 14. Controls and Procedures

CTS maintains a set of disclosure controls and procedures designed to ensure that information required to be disclosed by CTS in reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms. Within the 90-day period prior to the filing of this report, an evaluation was carried out under the supervision and with the participation of CTS’ management, including the chief executive officer and chief financial officer, of the effectiveness of CTS’ disclosure controls and procedures. Based on that evaluation, the chief executive and financial officers have concluded that CTS’ disclosure controls and procedures are effective.  Subsequent to the date of their evaluation, there have been no significant changes in CTS’ internal controls or in other factors that could significantly affect these controls.

13

The company's management, including the CEO and CFO, does not expect that our disclosure controls and procedures or our internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs.
