On-going Acquisition/Merger Activities

In pursuit of the Company’s growth strategy, management is continuously evaluating acquisition/merger opportunities with numerous companies. Companies of interest are leading manufacturers, distributors and service providers who compete with technology advantage, are generating internal growth, and show potential for strong synergy with the Company’s technology, manufacturing operations and marketing and sales organization.

Products and Services

Industrial Measurement

The Company’s industrial sensor and control products consist of a wide range of NTEP and OIML approved, EX, Factory Mutual and IP rated load cells, transducers, translators and sensors. These devices, representing a core SI technology, are electromechanical components that convert a physical force to an electrical signal. When matched with microprocessor-controlled digital electronics, they measure forces such as pressure, weight, mass and torque. Commercially, the products are used for measurement, inspection and control. SI sensor and control products are principally used in electronic weighing equipment; batching, blending, mixing, fill-by-weight and product inspection operations and, machinery operation and control systems. SI controls/instrumentation is normally designed as an integral part of a complete weighing system. In recent years, SI instrumentation has been expanded to provide users with the ability to acquire, record in memory and download to management information systems operational information other than weight information. In this expanded capacity, SI instrumentation becomes a critical link between operations and management information systems.

SI designs and manufactures dynamic and static electronic weighing equipment and systems for use in a wide array of industrial applications. As a result of the uniqueness of the Company’s combined sensor, weighing and automation system technologies, SI is one of few manufacturers in the industry who design and manufacture all three of the primary components of an electronic scale. These components are the load-handling structure, sensors and instrumentation. Many manufacturers of conventional scale systems manufacture only load-handling structures, outsourcing to industry suppliers their sensor and instrumentation requirements. The Company utilizes its expertise and manufacturing know-how in each of these critical components to competitive advantage and believes our broad expertise can be exploited through our acquisition/integration growth strategy.

Dynamic weighing systems are installed on transportation vehicles, material-handling equipment and in manufacturing process systems for weight measurement of goods and materials. Weight information generated by these systems has broad application including loading, transporting and delivery payload management; manufacturing process, inventory and quality control; and operations automation. Key products marketed under the AirScale, Allegany, Checkmate, Evergreen Weigh, Structural Instrumentation, RouteMan, SmartPin, The Logger, Trojan, and Tuffer trade names are dynamic “weigh-in-motion” and mobile on-board vehicle and material-handling equipment scales, pallet weighers, crane scales and engineered system scales. SI systems are available as standard products for use with most major original equipment manufacturer (OEM) trucks, trailers, forklifts, loaders, cranes and lifting devices. Products are marketed predominately to the agriculture, construction, forestry, foundry, freight, manufacturing, mining, steel, transportation and waste management industries.

Depending on application, specific economic benefit is derived from reduced overweight vehicle fines and delays; reduced time loading, checkweighing and adjusting loads to maximum legal limits; reduced mileage and driving time to checkweighing locations such as commercial in-ground truck scales; immediate measurement and recording of pick-up and delivery weights; reduced equipment abuse, maintenance downtime and expense; and higher capital equipment capacity utilization. Additionally, the weight information produced by these systems is often the critical measurement in controlling, batching, blending and mixing operations in the manufacture of materials.

3

All systems include force measurement sensors and microprocessor-based electronic instrumentation. The instrumentation supplies power to the sensors, provides all operator interface and controls, processes sensor electronic signals to determine weights, and displays and records in memory weight information and other inputs from the system and/or the operator. Force measurement sensors employing electronic strain gage technology measure force values. The electrical resistance of force measurement sensors changes proportionally to the force applied; thus the return signal to the meter varies by load or force.

The Company’s static weighing system product line consists of scales designed for numerous industrial and aviation weighing applications. Key products marketed under the trade names Air Guardian, Jet Weigh, Lodec, MTSERIES, Road Guardian, and Road Runner are permanent and portable axle scales, wheel-load weighers, canister load cell systems and heavy-capacity platform scales. Much like dynamic weighing systems, the static weighing systems have broad industrial application. Key markets in which these products enjoy significant market share include aggregate, aviation, construction, freight terminals, land remediation, mining and weight enforcement. Static weighing systems utilize the same technology as dynamic weighing systems; however, they are designed to weigh loads in a static or stationary mode.

Industrial Automation

SI’s industrial automation products consist of load handling, moving and positioning equipment and systems. These products often utilize highly specialized air-bearing movement systems to move loads of any weight efficiently and with extreme precision. Air bearings are air-cushion devices that are used to “float” heavy loads on a thin film of air. Additionally, the Company manufactures systems utilizing water bearings for use in large outdoor applications where water is used as the flotation medium rather than air. These products, marketed under the trade names AeroCaster, AeroGo, AeroPallets, AeroPlanks and AirShuttle are the world leaders in practical and efficient methods of movement, transfer, location, rotation and alignment of materials and products weighing from several hundred pounds to more than 6,000 tons.

The Company’s industrial automation product line comprises two distinct categories. The first is a standard product line of rugged, industrial, off-the-shelf air-cushion devices that allow a single person to easily and safely move loads weighing from a few hundred pounds to many tons. Standard products routinely move manufacturing fixtures, printing press bulky paper rolls, jet engines, and other heavy loads. The other category of the product line consists of engineered products. Engineered products and specialized systems designed and manufactured by the Company in recent years are currently moving 100,000-pound dies, launching ships, moving 4,500-ton stadium sections, transporting aerospace booster rockets and moving large assemblies in and out of assembly line operations in numerous heavy equipment manufacturing facilities.

Additional examples of engineered products include: automated guided vehicle systems, transporters, assembly line turntable systems, precision handling and positioning fixtures, quick die/mold changing carts, caisson manufacturing and moving systems, and aircraft inspection turntables.

SI industrial automation products commonly represent significant economic benefit in comparison to conventional material handling equipment through lower capital investment in manufacturing site construction, preparation and system installation, and greater operating efficiencies based on system versatility (not limited to following rails or tracks, as typically required with cranes and conveyors). These systems often represent the most viable means for handling extreme material handling applications involving very heavy loads, precision movement and positioning, and high efficiency assembly line automation.

Marketing and Sales

The Company’s products are marketed throughout the world primarily through 300 distributors and manufacturer representatives, each operating in a specific trade area and serving industrial customers, engineering firms and various government agencies. In addition to headquarters marketing and sales personnel, and subsidiary business unit marketing and sales operations, the Company maintains North American regional sales offices in California, Maryland, Michigan, North Carolina, Oregon, Washington and British Columbia, Canada; and European regional sales offices in France, Germany, the United Kingdom and the Netherlands. Company regional sales personnel assist distributors and representatives, make direct sales calls on potential customers in areas not covered by distribution, and support the Company’s direct major accounts.

The Company generates leads through a full complement of marketing practices, including advertisement in industry publications, direct-mail advertising, trade show participation and telemarketing. Headquarters and subsidiary personnel initiate the Company’s sales process on all inquiries by providing the inquirer with information on Company products and services and qualifying the lead. After qualification, inquiries are either maintained in sales for follow-up by Company sales personnel and distribution, or dispatched to engineering for design, cost estimating and preparation of price quotations or bid packages.

Due to the Company’s mix of standard off-the-shelf products and custom-engineered products, the time period between initial inquiry, purchase order receipt and shipment varies widely. Standard product orders are normally shipped within one to three days of purchase order receipt at published prices and with trade terms of FOB factory and 30 days net. Engineered products and projects are subject to specific contract terms negotiated between the Company and customer. Typically, contract terms provide for progress payments, provision for change orders and, on longer-term projects, provision for inflation- based price adjustment. On certain projects, the Company provides complete site preparation, system installation, start-up and customer training services. In this capacity, from time to time, the Company serves as a contractor on a time and material basis. The Company’s business is not seasonal in nature.

Market Conditions and Competition

Market Conditions

Worldwide capital expenditures for industrial measurement and automation equipment and systems have averaged about $70 billion in recent years, with domestic spending accounting for approximately 30% of the total. Overall industry growth normally approximates inflation. Over the past eighteen months the Company believes the market and specifically key market sectors in which it does business has contracted due to the global manufacturing recession, which began in calendar year 2000. Beyond the current economic situation, the Company believes its unique products, diversity of markets and worldwide geographic presence present significant opportunities for internal growth within the industry.

Product uniqueness (niche products) is a competitive advantage for SI. Manufacturers of conventional mature products competing for market share with non-differentiated products normally compete primarily on product price and availability. SI’s unique products such as dynamic weighing and air-bearing load-handling and factory automation systems frequently compete within the industry as substitute products or as an alternative means for meeting the customers’ needs. As a result of this high level of product differentiation and the application versatility of SI’s unique products, the Company believes demand for SI products is more elastic than demand for conventional products within the industry.

Market diversity is a growing competitive advantage for SI. Over the past few years, SI has been redirecting its focus to new markets in an effort to mitigate a sharp capital spending downturn in the Company’s traditionally strong forestry and waste management markets. Since the 1996 acquisition of Evergreen Weigh cross-selling of products and integration of Company sales organizations have steadily increased market share in several markets including, aggregate, aviation, and construction industries. With the acquisition of AeroGo in fiscal 1997, and the acquisitions of NV Technology, Allegany Technology and Revere Transducers in fiscal 1998, the Company has

5

further expanded its market diversity and potential for revenue synergies. The Company intends to capitalize on its growing market diversity, worldwide presence and cross-selling opportunities with an expanding product line to create internal growth.

SI maintains inventories of raw materials, work-in-process and finished goods. To supply products with competitive availability, the Company carries approximately 47% of inventory in finished goods. While the Company manufacturers the majority of its value-added components, certain components, manufacturing processes and sub-assemblies are outsourced. Outsourced items are normally purchased on fixed price contracts on a just-in-time basis. Should the need arise, the Company believes that any supplier and/or subcontractor could be replaced without significant disruption to its business.

Competition

Competition in the industrial measurement and automation equipment and system industry is extremely fragmented with approximately 6,000 manufacturers and a greater number of distributors and service companies. To the Company’s knowledge, there are no competitors with the same product mix as SI. Direct competitors (competing head-to-head with similar products) normally compete on a single product line and are smaller and may have less financial resources than SI. General industry-wide competitors (competing with alternative conventional products) range from very small, local companies to large, international companies with greater financial resources than SI.

In the dynamic and static weighing systems product line, direct competitors are all smaller, privately held companies. Occasionally and on specific applications, the weighing systems product line competes as an alternative product with larger companies that manufacture conventional, industrial weighing systems. These companies include Cardinal Scale Manufacturing Company, Fairbanks Scale Company, Mettler-Toledo Holding, Inc. and Weigh-Tronix, Inc. Competition among larger manufacturers of conventional weighing systems, due to lack of product differentiation, is principally based on price, local dealer trade-area presence and relationships, and product availability.

Competition in the industrial sensor and control product line varies widely depending on customer type and application. Industry standard sensors sold directly to large industrial scale manufacturers compete primarily on price, quality and service. Standard and custom sensors sold to OEMs of other types of products and equipment, and to user customers in process industries, primarily compete on the supplier’s ability to provide engineering expertise and assistance, quality, and on-going customer support and service. Competitors range from small, local companies to large, international companies.

Competition in load handling and factory automation products is similar to weighing system products. In the air and water bearing product line, all competitors are smaller, privately held companies which may have less financial resources than the Company. Direct competitors include Airfloat, Hovair, and Aircaster. In custom-engineered products and projects, the Company normally competes as a substitute or alternative product versus conventional material-handling equipment manufactured by companies ranging in size from much smaller to significantly larger than the Company.

International markets vary widely in competitive issues. In some countries, price competition is more intense than in North America, while in others prior relationships and product quality receive more customer emphasis than do marginal pricing differentials, thus price competition is less intensive. As a result of product uniqueness, innovative design solutions, quality of product and dependability, SI products and services are frequently sold in situations where the Company is not the low bidder.

Significant Customers

Historically the Company’s primary customers have been transportation, agriculture, forestry, manufacturing, waste management and general industrial companies. Over the past few years, as a result of the

6

Company’s growth strategy, the customer base has expanded to include the aviation/aerospace, automotive, food processing, construction and maritime industries. Significant customers in recent years include Boeing, Caterpillar, Carrier, Chrysler, Ford, Hyundai, Mettler-Toledo, Lockheed, Michelin, Mitsubishi, NASA, Siemens, and Thiokol.

While a significant portion of the Company’s annual revenues represent repeat business from its customers, no individual customer represents 10% or more of the Company’s revenues.

Acquisition History

Acquisition of Evergreen Weigh, Inc.

In April 1996, the Company acquired Evergreen Weigh, Inc. (Evergreen), a Washington corporation. Evergreen is a manufacturer of dynamic and static weighing systems. Evergreen’s primary products include weigh-in-motion on-board scales for material-handling equipment, axle scales and wheel-load weighers. Key markets served by Evergreen products include the aviation, heavy construction, mining, quarry and transportation industries. The acquisition of Evergreen expanded the Company’s product line and increased the number of markets in which the Company sells products. SI and Evergreen sales organizations merged into one integrated sales organization shortly after the acquisition.

Acquisition of AeroGo, Inc.

In July 1997 the Company acquired AeroGo, Inc., a Washington corporation. AeroGo is a world leader in the design and manufacture of load-handling, moving, positioning and factory automation equipment and systems. AeroGo products, utilizing both standard and highly specialized air bearing movement systems, are marketed chiefly to aviation/aerospace, automotive, construction, manufacturing, maritime and general industry. AeroGo’s factory automation expertise lies in the design and manufacturing of heavy load moving equipment, die carts, automated guided vehicle systems, transport skates, sideloaders, step conveyors and flexible manufacturing systems. The acquisition of AeroGo provided the Company with an entrance to the industrial automation industry.

Acquisition of NV Technology, Inc.

In February 1998, the Company acquired NV Technology, Inc. (NV), a Nevada corporation. The transaction, which was a tax-free merger, was accounted for as a pooling-of-interest. NV is a manufacturer of high-performance, stainless steel load cells and sensors. The addition of NV’s National Institute of Science & Technology (NIST) certified products expanded the Company’s business in legal-for-trade, weighing and process control applications.

Acquisition of Allegany Technology, Inc.

In July 1998, the Company acquired Allegany Technology, Inc. (Allegany), a Delaware corporation. Allegany is a leading designer and manufacturer of specialty load cells and sensors, industrial crane, and lift truck scales, along with billet weighing systems. Allegany’s unique billet weighing systems increase productivity and profitability in the steel and heavy metals industries. Other major markets for Allegany products include aerospace, distribution, manufacturing, transportation and warehousing. Allegany products expanded the Company’s strong position as a manufacturer of weighing products for niche markets.

Acquisition of Revere Transducers

In July 1998, the Company acquired Revere Transducers, Inc. and Revere Transducers Europe B.V. (Revere) from Harnischfeger Industries (NYSE-HPH). Revere is headquartered in Tustin, California, with

7

operations in Tustin and Breda, the Netherlands. Revere is one of the four largest manufacturers of electronic weighing load cells, sensors and related devices in the industry, with worldwide market share estimated at 8%. In addition to a highly recognized brand name, the acquisition of Revere brought the Company new technology and manufacturing capability in the design and manufacture of proprietary strain gages and a manufacturing facility and marketing organization in Europe.

Restructuring Plan

In the third quarter of 2001, the Company announced a Restructuring Plan to address a significant decline in sales brought about by the then nine-month old global manufacturing recession and to position the Company for improved profitability in the future. The plan announced was comprised of the three key components. First, was the consolidation of the SI/Allegany business unit and Revere Transducers, resulting in the closing of operations in Cumberland, Maryland. Second, the plan called for development of offshore manufacturing sources to reduce costs on certain high-volume, highly competitive load cells and sensors. The third component of the plan was for a downsizing of the Company’s Tustin, California, headquarters and manufacturing facility to a more appropriately sized facility in the same general area. In recognition of the expenses associated with this restructuring, the Company recorded a $3,844,000 charge in fiscal 2001 to cover expenses related to implementation of the plan and costs associated with elimination of fixed assets and employee severance. Key cost components of the plan include: (1) reduction of manufacturing capacity by abandoning and/or downsizing facilities, (2) disposing of redundant assets, (3) termination of approximately 50 employees, and (4) outsourcing a significant portion of the combined operation’s higher volume products.

The Company has been unable to sublet the Maryland facility. An additional restructuring charge of $486,000 was recorded in 2003 representing the balance of lease payments for the facility. The Company will continue to actively market it, however at this time, it is uncertain if a suitable tenant can be found within the lease period. See additional discussion in Item 7.

Goodwill Impairment

As a result of the evaluation of its Allegany Technology subsidiary in connection with the restructuring plan in 2001 noted above, the Company estimated the discounted future cash flows of the continuing products, and determined that almost 40% of the remaining goodwill associated with the acquisition of companies previously incorporated into the Allegany Technology operation has been impaired. In accordance with Statement of Financial Accounting Standards No. 121 “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of”, a $2,000,000 charge for goodwill impairment was recorded in operating expenses for the quarter ended April 30, 2001.

Backlog

At July 31, 2003, the Company’s backlog was $3,093,000, compared with $4,286,000 on July 31, 2002. The Company’s backlog consists of written orders and commitments believed to be firm, approximately 95% of which is shippable in fiscal 2004. Purchase orders and contracts for products and services are from time to time modified and/or canceled by mutual consent between the Company and the customer. Therefore, the backlog on any specific date may not be indicative of the Company’s future performance.

Employees

At July 31, 2003, the Company employed 240 full time employees.

Sources of Supply

The materials and components used by the Company to manufacture its products are available from a variety of sources. The Company believes that it is not dependent at this time on any particular supplier for either its materials or components and has experienced no difficulty in obtaining supplies.

8

Patents and Trademarks

The Company holds numerous patents on various force measurement devices and weighing system design applications. The patents have expiration dates ranging from 2003 to 2016. The Company also has patent license agreements to build force measurement devices under patents held by others. The license agreements are fully paid up and irrevocable for the lifetime of these patents. The Company has no reason to believe its patents are not valid. However, if the patents were successfully contested, management does not believe it would have a material adverse impact on the Company.

Financial Information about Foreign Operations

Foreign Operations

Included in the consolidated balance sheet at July 31, 2003 are the identifiable assets of the Company’s subsidiary, Revere Transducers Europe B.V., which total approximately $4,327,000. The Company acquired Revere Transducers Europe, located in the Netherlands, at July 1, 1998.

The Company derives approximately 59% of its revenues from customers within the United States. Approximately 30% come from sales to customers in 16 different countries in Europe. The balance of sales are to Canada, Mexico and Latin America. Sales outside the United States are primarily to developed countries.

NET SALES

Net sales for the year ended July 31, 2003 increased to $33,047,000 or 1.3% from $32,613,000 for the year ended July 31, 2002. The increase in sales in industrial measurement products is primarily attributable to favorable exchange rates from Euros to the dollar. Sales of industrial automation products decreased $682,000 or 9.5%, due to decreased volume demand for these products resulting from lower capital equipment spending globally.

Net sales for the year ended July 31, 2002 declined to $32,613,000 or 10.1% from $36,291,000 for the year ended July 31, 2001. The decrease in sales was primarily attributable to continuation of the global manufacturing recession’s impact on capital equipment markets. Following a sales decline of 7-16% year-over-year in the first three quarters of 2002, the fourth quarter sales were comparable to 2001. Sales of industrial automation products decreased $796,000 or 9.9%.

GROSS PROFIT

Gross profit for the year ended July 31, 2003 decreased $180,000 or 1.5% to $11,539,000 from $11,719,000 for the year ended July 31, 2002. The decrease in gross profit was primarily attributable to continued downward price pressure in many of the Company products, and a shift to lower margin products during the second half of the year as product mix continued to shift between scale components and complete scale systems. Traditionally, the Company’s complete scale system products earn substantially higher gross profit than the load cell or scale components product line.

Gross profit for the year ended July 31, 2002 decreased $230,000 or 1.9% to $11,719,000 from $11,949,000 for the year ended July 31, 2001. The decrease in gross profit was primarily attributable to lower sales volume, however, the contribution of the benefit of outsourcing products to lower cost producers resulted in a significant improvement in the gross margin percentage. The corresponding gross margins for the periods were 35.9% and 32.9%, respectively. The year-over-year increase in gross margin was the result of the consolidation of the Company’s operations and placing into effect the restructuring.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

Selling, general and administrative expenses for the years ended July 31, 2003 and 2002 were $8,537,000 and $8,023,000 respectively. The increase of $514,000 or 6.4%, was the result the expansion of the Company’s marketing efforts including staff additions of $418,000. Selling, general and administrative expenses as a percentage of sales were 25.8% in 2003 as compared to 24.6% in 2002. Selling, general and administrative

14

expenses for industrial automation decreased by $285,000 or 11.7% as a result of lower sales activity and reductions of administrative costs where practical.

Selling, general and administrative expenses for the years ended July 31, 2002 and 2001 were $8,023,000 and $8,971,000, respectively. Selling, general and administrative expenses as a percentage of sales were 24.6% in 2002 as compared to 24.7% in 2001. The decrease in total expenditures was the result of consolidating the Company’s sales, administrative and engineering functions, resulting in a $561,000 reduction in personnel costs.

RESEARCH, DEVELOPMENT AND ENGINEERING EXPENSES

Research, development and engineering expenses for the years ended July 31, 2003 and 2002 were $1,565,000 and $1,388,000, respectively. The increase of $177,000 or 12.8% represents salaries for engineering support of manufacturing. The Company’s expenditures are primarily for sales, manufacturing and customer support and development of product enhancements.

Research, development and engineering expenses for the years ended July 31, 2002 and 2001 were $1,388,000 and $1,621,000, respectively. This is a decrease of $233,000 or 14.4%, attributable primarily to a reduction in personnel costs of approximately $100,000. The decrease was also attributable to the business unit combinations and facility consolidation implemented during the year.

AMORTIZATION EXPENSES

In 2003, amortization of goodwill was discontinued when the Company changed the treatment of amortization of goodwill to comply with SFAS 142, “Goodwill and Intangible Assets.”

Intangible amortization expenses amounted to $365,000 in 2002 as compared to $426,000 in 2001, and were lower due to the impairment in the carrying value of the unamortized goodwill recorded during the 2001 restructuring.

INTEREST AND OTHER INCOME

Interest expense in 2003 was $976,000 in comparison to $904,000 in 2002. A larger line of credit borrowings accounted for the increase in interest expense as compared to the same period in the prior fiscal year, while interest rates remained relatively stable. Other income was $153,000 in 2003 as compared to $94,000 in 2002.

Interest expense for 2002 decreased $660,000 or 42.2% from $1,564,000 in 2001 to $904,000 in 2002. This decrease was directly attributable to lower interest rates during the current year in comparison to the prior year and a reduction of overall debt of $1,027,000.

RESTRUCTURING CHARGES

In the third quarter of 2001, the Company announced a Restructuring Plan to address a significant decline in sales brought about by the then nine-month old global manufacturing recession and to position the Company for improved profitability in the future. The plan announced was comprised of the three key components. First, was the consolidation of the SI/Allegany business unit and Revere Transducers, resulting in the closing of operations in Cumberland, Maryland. Second, the plan called for development of offshore manufacturing sources to reduce costs on certain high-volume, highly competitive load cells and sensors. The third component of the plan was for a downsizing of the Company’s Tustin, California, headquarters and manufacturing facility to a more appropriately sized facility in the same general area. In recognition of the expenses associated with this restructuring, the Company recorded a $3,844,000 charge in fiscal 2001 to cover expenses related to implementation of the plan and costs associated with elimination of fixed assets and employee severance. Key cost components of the plan include: (1) reduction of manufacturing capacity by abandoning and/or downsizing

15

facilities, (2) disposing of redundant assets, (3) termination of approximately 50 employees, and (4) outsourcing a significant portion of the combined operation’s higher volume products.

The Company was in negotiations to sublet the Maryland facility in the fall of 2002, but was subsequently unable to secure a long-term tenant. The Company has since been unable to sublet the Maryland facility and accordingly, an additional restructuring charge of $486,000 was recorded in 2003 representing the balance of lease payments for the facility. The Company will continue to actively market it, however at this time, it is uncertain if a suitable tenant can be found within the lease period. The Company will relocate the Tustin operations to a new facility in September 2004.

INCOME TAX BENEFIT

Income tax benefit for the years ended July 31, 2003 and 2002 was $1,078,000 and $540,000, respectively. The Company’s effective tax rate (income tax benefit/expense as a percentage of pretax income) was 905.9% and 47.7% in 2003 and 2002, respectively. The U.S. federal corporate income tax rate exceeds the effective tax rate due primarily to the amortization of intangible assets that are not deductible for income tax purposes (in 2002 only), state and foreign income taxes, utilization of net operating loss carryforward and the valuation allowance for the deferred tax assets. The valuation allowance for deferred tax was reduced in 2002 and eliminated in 2003. Based on results from 2002 and 2003, the Company expects to be in a profitable position and able to realize the deferred tax assets in the future and has accordingly reduced the valuation allowance.

CRITICAL ACCOUNTING POLICIES

The discussion and analysis of the Company’s financial condition and results of operations is based upon the Company’s consolidated financial statements which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. On an on-going basis, the Company evaluates estimates, including those related to the valuation of inventory and stock adjustments, for reasonableness. The Company bases its estimates on historical experience and on various other assumptions that management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions and conditions.

SI Technologies, Inc. (SI or Company) designs, manufactures and markets high performance industrial sensors, weighing and factory automation equipment, and related products. SI products incorporate devices, equipment and systems for the handling, inspection and measurement of goods and materials. Key markets served by SI include aerospace/aviation, food, forestry, manufacturing, mining, transportation/distribution and waste management. The Company sells throughout the United States and international markets. Approximately 48% of total revenues are international. Additional disclosure regarding components of the Company’s businesses is in Note N—Industry and Geographic Area Segment Information.

1.    Equity Compensation Plan Information

The Company accounts for stock-based employee compensation under the requirements of APB Opinion No. 25, which does not require compensation to be recorded if the consideration to be received is at least equal to fair value at the measurement date. Nonemployee stock-based transactions and stock warrants are accounted for under the requirements of SFAS No. 123, Accounting for Stock-Based Compensation, which requires compensation to be recorded based on the fair value of the securities issued or the services received, whichever is more reliably measurable.

16

2.    Revenue Recognition and Accounts Receivable

The Company recognizes revenue only when all of the four following criteria are met: 1) Persuasive evidence of an arrangement exists, usually in the form of a written purchase order; 2) Delivery has occurred (or a shipment has been made, depending upon the terms of the purchase order) or services have been rendered; 3) The Company’s price to the buyer is fixed or determinable, usually evidenced by a written purchase order; and 4) Collectability is reasonably assured, based on credit evaluation and history with the customer.

Additionally, on long-term contracts, sales are recorded based on the percentage that incurred costs bear to the total estimated costs at completion. Estimated cost to complete is based on the budget, incurred cost, risk assessment of the cost, and is then adjusted for normal/historical variance of project actual versus budget. Estimated losses are recorded in total when they become evident. These contracts are generally billed and collected based on contractual milestones throughout the project.

3.    Reserves

Valuation allowances are maintained for doubtful accounts for estimated losses from the inability of the Company’s customers to make required payments. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. All receivable accounts are reviewed regularly by management and written off against the uncollectable reserve when it is determined that the account cannot reasonably be expected to be collected. Recoveries of trade receivables previously written off are recorded when received. No interest is charged on past due accounts.

Inventories are stated at the lower of cost or market. Each quarter, the Company evaluates its inventories for excess quantities and obsolescence. These estimates are dependent on the Company’s assessment of current and expected orders from its customers. Management estimates a reserve percentage for the estimated net realizable value of slow moving product based upon the number of years sales on hand. The Company reserves for potential excess and obsolete inventory based upon historical usage.

The Company offers warranties of various lengths to its customers depending on the specific product and terms of the customer purchase agreement. The average length of the warranty period is 12 months. The Company’s warranties require it to repair or replace defective products during the warrant period at no cost to the customer. At the time the product revenue is recognized, the Company records a liability for estimated costs that may be incurred under its warranties. The costs are estimated based on historical experience and any specific warranty issues that may have been identified. (Although historical warranty costs have been within expectations, there can be no assurance that future warranty costs will not exceed historical amounts.) The Company periodically assesses the adequacy of its recorded warranty liability and adjusts the balance as necessary.

Management also records a valuation allowance to reduce the Company’s deferred tax assets to the amount that is more likely than not to be realized. Management considers estimated future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance.

4.    Income taxes

Deferred taxes are provided on a liability method whereby deferred tax assets are recognized for deductible temporary differences, and deferred tax liabilities, including operating loss carryforwards, are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for effects of changes in tax laws and rates on the date of enactment.

17

5.    Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Depreciation is provided in amounts sufficient to relate the cost of depreciable assets to operations over their estimated service lives, principally on a straight-line basis. Leasehold improvements are amortized over the lives of the respective leases or the service lives of the improvements, whichever is shorter. Estimated service lives of property and equipment are as follows:

The straight-line method of depreciation is followed for substantially all assets for financial reporting purposes, while accelerated methods are used for tax purposes.

6.    Goodwill

In June 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 142, Goodwill and Other Intangible Assets. SFAS No. 142 addresses financial accounting and reporting for acquired goodwill and other intangible assets. The Company adopted SFAS 142 effective August 1, 2002.

In conjunction with the adoption of SFAS No. 142, the Company was required to carry out a transitional goodwill impairment evaluation, which requires an assessment of whether there is an indication that goodwill is impaired as of the date of adoption. Initially, the Company identified its reporting units and determined the carrying value of each reporting unit by assigning the assets and liabilities (including goodwill) to those reporting units as of the date of adoption. If the fair value of a reporting unit was below the unit’s carrying amount, as computed in step one, the Company must complete step two of the transitional goodwill impairment test for that reporting unit as soon as possible, but not later than the end of the year of adoption. If the implied fair value of a reporting unit’s goodwill is less than its recorded goodwill, a transitional goodwill impairment loss will be recognized and reported as the cumulative effect of a change in accounting principle in accordance with Accounting Principles Board Opinion (APB) No. 20, Accounting Changes. Any subsequent impairment losses resulting from events or circumstances that occur after the first day of the fiscal year in which SFAS No. 142 is adopted will be reported as a component of income from continuing or discontinued operations, as appropriate.

Upon adoption of SFAS No. 142, management determined there were three reporting units. The carrying value of each respective reporting unit was compared to its current fair value determined using a discounted future cash flows approach. Due to the fair value of each reporting unit exceeding its carrying value, management determined no impairment existed. Management completed its annual goodwill impairment evaluation as of  July 31, 2003, and further concluded that no additional impairment exists.

7.    Impairment of long lived assets

The Company periodically reviews its long-lived assets, including patents, to determine potential impairment by comparing the carrying value of the long-lived assets with the estimated future net undiscounted cash flows expected to result from the use of the assets, including cash flows from disposition. Long-lived assets evaluated for impairment are grouped with other assets to the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Should the sum of the expected future net cash flows be less than the carrying value, the Company would recognize an impairment loss at that date. An impairment loss would be measured by comparing the amount by which the carrying value exceeds the fair value (estimated discounted future cash flows) of the long-lived assets. For the year ended July 31, 2003, management has determined that no impairment of long-lived assets, including patents, exists.

18

Changes in circumstances, such as the passage of new laws or changes in regulations, technological advances or changes to the Company’s business strategy, could result in the actual useful lives of long-lived assets differing from initial estimates. Factors such as changes in the planned use of equipment, customer attrition, contractual amendments or mandated regulator requirements could result in shortened useful lives. In those cases where the Company determines that the useful life of a long-lived asset should be revised, the Company will amortize or depreciate the net book value in excess of the estimated residual value of its revised remaining useful life.

8.    Use of Estimates

In preparing the Company’s financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates and assumptions made by management are used for, but not limited to, the allowance for doubtful accounts and sales returns, reserves for slow moving and obsolete inventory, warrant obligations, excess facility capacity, deferred tax valuation allowances and recoverability of the carrying value of long-lived assets, including goodwill.

9.    Pending Accounting Pronouncements

The FASB has issued Interpretation No. 46, “Consolidation of Variable Interest Entities”—an interpretation of Accounting Research Bulletin (“ARB”) No. 51. This Interpretation defines a variable interest entity and provides that if a business enterprise has a controlling financial interest in a variable interest entity, the assets, liabilities, and results of the activities of the variable interest entity should be included in consolidated financial statements with those of the business enterprise. Furthermore, the Board indicates that the voting interest approach of ARB No. 51 is not effective in identifying controlling financial interests in entities that are not controllable through voting interest or in which the equity investors do not bear the residual economic risk. This Interpretation applies immediately to variable interest entities created after January 31, 2003, and to variable interest entities in which an enterprise obtains an interest after that date. It applies in the first fiscal year or interim period beginning after December 15, 2003, to variable interest entities in which an enterprise holds a variable interest that it acquired before February 1, 2003. Management believes the implementation of this Interpretation will not have a material effect upon the Company’s consolidated financial statements.

In May 2003 FASB issued SFAS No. 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity”, which requires that certain financial instruments previously presented as equity or temporary equity be presented as liabilities. Such instruments include mandatory redeemable preferred and common stock, and certain options and warrants. SFAS 150 is effective for financial instruments issued, entered into or modified after May 31, 2003 and is generally effective at the beginning of the first interim period beginning after June 15, 2003. The adoption of SFAS 150 is not expected to have a material effect on the Company’s financial position or results of its operations.

INFLATION

Historically, the impact of inflation has been negligible, as the Company has been able to offset the effects through efficiency and price adjustments.

CONSOLIDATED LIQUIDITY, CAPITAL RESOURCES AND FINANCIAL CONDITION

At July 31, 2003, the Company’s cash position was $284,000 compared to $238,000 at July 31, 2002. Cash available in excess of that required for general corporate purposes is used to reduce borrowings under the Company’s line of credit. Working capital increased to $1,624,000 from $1,125,000 at July 31, 2002.

The Company’s existing capital resources consist of cash balances and funds available under its line of credit, which are increased or decreased by cash provided by or used in operating activities. Cash used by operating activities in 2003 was $612,000. Operating income, reduction of trade receivables and the cash benefit of depreciation was used to reduce trade payables and increase inventories. Management anticipates generating cash from operating activities in 2004 by reducing inventories assuming revenues remain stable.

The Company’s cash requirements consist of its general working capital needs, capital expenditures, and obligations under its leases and notes payable. Working capital requirements include the salary costs of employees and related overhead and the purchase of material and components. The Company anticipates capital expenditures of approximately $280,000 in 2004 as compared to $270,000 in 2003. The Company expects to refinance its current lines of credit and has sufficient cash flow available to pay current maturities of long-term debt of $1,898,000. A portion of the current maturities represents a note which has been renewed in the past. As of July 31, 2003, the Company had $385,000 available under its lines of credit.

In June 2002, the Company amended its principal credit agreement with its bank. The terms provide for a revolving line of credit up to a maximum of $6,500,000 with interest at prime plus 2.75%. Monthly payments on the line are interest only with principal due January 2, 2004. The credit agreement provides a term note for $1,500,000 with interest at prime plus 3.25%. Monthly payments on the new term note are $25,000 plus interest with principal due January 2, 2004. Monthly payments on the existing note payable are reduced to $56,058 plus interest at prime plus 1.75%, with the remaining terms of the existing note unchanged. The line and both notes are secured by substantially all of the Company’s assets and are cross-collateralized and cross-defaulted. The Company is required to maintain certain levels of earnings before interest, taxes, depreciation and amortization, tangible net worth and fixed charge coverage and may not pay any cash dividends under terms of the agreement. The Company was in violation of one of these covenants at year end and has received a waiver from the bank.

The Company believes that cash flow from operations and funds available under its bank facilities will be sufficient to meet the Company’s working capital needs and principal payments on long-term debt. No assurances can be made that the debt can be refinanced or replaced at favorable rates.

In the 4th Quarter the Company completed a private placement, as more fully described in Item 5, in which $750,000 of common stock was sold along with warrants.

20

CONTRACTUAL COMMITMENTS

As of July 31, 2003 the Company had contractual obligations in the form of non-cancelable operating leases (see Note H to the Consolidated Financial Statements) and long-term debt obligations (see Note E to the Consolidated Financial Statements), as follows:

(in thousands)

Included in operating leases are payments included in other liabilities for which reserves have been established as more fully described in Note F to the financial statements.

INFORMATION REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements other than statements of historical facts included in the preceding discussion regarding the Company’s financial position, business strategy and plans of management for future operations are forward-looking statements. Although the Company believes that the expectations reflected in such forward-looking statements are reasonable; it can give no assurance that such expectations will prove to be correct.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk represents the potential loss that may impact our financial position, results of operations or cash flows due to adverse changes in the financial markets. The Company is exposed to market risk from changes in the base rates on our variable rate debt.

Interest rates-the domestic bank revolving line of credit and term debt (totaling $11,379 at July 31, 2003) bear interest at a variable rate of prime (4.0% at July 31, 2003) plus an additional amount, as defined in each respective debt agreement.

The Company has experienced minimal foreign currency fluctuation.
