PART I
ITEM 1. BUSINESS
Overview
The Company is a leading designer and manufacturer of high-performance screw-in hydraulic cartridge valves and manifolds, which control force, speed, and motion as integral components in fluid power systems. The innovative floating construction of the Company’s screw-in cartridge valves and the design of the cavities in which they are installed provide demonstrable performance and reliability advantages compared to other available screw-in cartridge valves. The Company designs and manufactures one of the most comprehensive lines of screw-in hydraulic cartridge valves and manifolds in the world. The Company has generated a profit every year since 1972 and has paid a dividend every quarter since its initial public offering of securities in 1997. The Company believes that its success is primarily a result of its innovative product design, consistent high quality, superior product performance and the breadth of the markets it serves.
The Company sells its products primarily through a global network of independent fluid power distributors to a diverse universe of end users, for use in various “mobile” applications, such as construction, agricultural and utility equipment (historically, approximately 66% of net sales), and a broad array of “industrial” applications, such as machine tools and material handling equipment (historically, approximately 34% of net sales). While many of the Company’s end users are subject to cyclical demand for their products, the Company mitigates this exposure through the wide variety of applications and industries it serves. In 2005, sales to the Company’s largest distributor represented less than 7% of net sales, and approximately 50% of the Company’s net consolidated sales were outside the United States.
The Company was organized as a Florida corporation in 1986 to take over the operations of the business of the Company’s predecessor, Suninco, Inc. (f/k/a Sun Hydraulics Corporation). Suninco, Inc. was founded in 1970 by Robert E. Koski for the specific purpose of developing and promoting screw-in cartridge valve technology. The Company’s executive offices are located at 1500 West University Parkway, Sarasota, Florida 34243, and its telephone number is (941) 362-1200. The Company’s website is www.sunhydraulics.com.
Industry Background
Fluid power is one of three basic technologies, along with electrical and mechanical, utilized to achieve power transmission and motion control. Due to its mechanical advantage, fluid power is widely employed to move and position materials, control machines, vehicles and equipment, and improve industrial efficiency and productivity. Fluid power can perform work on very light loads with a high degree of accuracy or develop enormous forces to move and position materials and equipment that weigh many tons.
Screw-in hydraulic cartridge valves first appeared in the late 1950s as an alternative to conventional forms of hydraulic valves. Conventional hydraulic valves are generally larger in size, typically manufactured from cumbersome iron castings, relatively limited in their ability to interface with machinery and equipment, and are usually simple devices designed to control a single task. Screw-in cartridge valves represent a miniaturization of hydraulic valves, providing the same functional characteristics as conventional valves, but in a smaller package size. In addition to being lighter-weight and more compact, screw-in cartridge valves frequently offer significant advantages in interface flexibility and cost over conventional hydraulic valves.
Screw-in cartridge valves have significant marketplace acceptance because hydraulic system design engineers are easily able to develop multiple-function control systems. A number of screw-in cartridge valves can be grouped together in a manifold, creating a hydraulic control system that is functionally analogous to an electronic integrated circuit. End users can utilize screw-in cartridge valves and custom

manifolds to design an optimal solution for control of their fluid power systems that significantly reduces assembly time and expense.
Strategy
The Company will continue to design, manufacture, market and support, on a worldwide basis, differentiated high-performance and high-quality cartridge valves and integrated valve packages. The Company believes this focus supports its business objectives of sustaining revenue growth that will yield an above-average return on capital while achieving a high level of customer satisfaction. Key elements of the Company’s strategy include the following:
Deliver Value Through High-Quality, High-Performance Products. The Company’s products are designed with operating and performance characteristics that exceed those of many functionally similar products. Overall, the Company’s products provide high value because they generally operate at higher flow rates and pressures than competitive offerings of the same size. The Company tests 100% of its screw-in cartridge valves to ensure the highest level of performance on a consistent basis.
Achieve a High Level of Customer Satisfaction. The Company is a build-to-order operation that schedules orders to the customer’s request date. To ensure all employees are dedicated to meeting customer requests, the Company measures and posts monthly the percentage of shipments that satisfy the customers’ requests. In addition to meeting the above requirement, the Company tests 100% of the screw-in cartridge valves before shipment. The Company tests extensively all product returns due to questions regarding functionality and issues a written report of findings upon request. The Company believes that its long-term success is dependent upon its reputation in the marketplace, which in turn is a result of its ability to service its customers.
Offer a Wide Variety of Standard Products. The Company currently offers one of the most comprehensive lines of screw-in cartridge valves and manifolds in the world. The Company is committed to producing functionally superior, standard products that contain a high degree of common content to minimize work in process and maximize manufacturing efficiency. Products are designed for use by a broad base of industries to minimize the risk of dependence on any single market segment or customer. The Company expands its business through the development of new products that are complementary to its existing products.
Expand the Product Line. The Company is continuously engaged in new product development programs to offer new and better cartridge valve solutions to its customers. New cartridge products generally fit into existing cavities, often allowing them to be installed in existing standard manifolds. The Company recently has aggressively begun designing and introducing to the marketplace electro-hydraulic cartridge valves, including solenoid and proportional valves. The Company believes these products provide the opportunity to obtain sales for which it previously could not compete, and further believes that the electro-hydraulic cartridge valves will help increase sales of the Company’s other cartridge valve and manifold products.
Capitalize on Custom Manifold Opportunities. Because fluid power system design engineers are increasingly incorporating screw-in cartridge valves into custom control systems, the Company concentrates its efforts in custom manifolds in two ways. The Company designs and manufactures manifolds which incorporate the Company’s screw-in cartridge valves for sale to original equipment manufacturers (“OEMs”). To support this effort, the Company is able to design and manufacture manifolds at its operations in Sarasota, Florida and Kansas City, Kansas, USA, Coventry, England, Erkelenz, Germany, Seoul, Korea and at its operation in Shanghai, China. The Company also encourages competitive manifold manufacturers to utilize the Company’s screw-in cartridge valves in their manifold designs. The Company sells tooling for machining its cavities, allowing independent manifold manufacturers to easily incorporate the Company’s screw-in cartridge valves into their designs.
Expand Global Presence. The Company intends to continue to strengthen its global presence in the areas of distribution and international operations. The Company has strong distributor representation in most developed and developing markets, including North and South America, Western Europe, Asia, Australia, and South Africa. In 2005, the Company generated approximately 50% of its net sales outside the United States. The Company is continuing to expand its distribution arrangements in Eastern Europe and expand its market presence in China, Central and South America. The Company believes that further

expansion of its international facilities will enhance its competitive position in certain foreign markets. In addition, custom manifolds provide an opportunity for operating units and distributors to offer significant value-added content through the local production of manifolds that incorporate the Company’s screw-in cartridge valves. This strategy helps minimize potential tariffs and duties that could inflate the price of the Company’s products in foreign markets.
Maintain a Horizontal Organization with Entrepreneurial Spirit. The Company believes that maintaining its horizontal management structure is critical to retaining key personnel and an important factor in attracting top talent from within the hydraulic valve and manifold industry. The Company strives to maintain its horizontal management structure that encourages communication, creativity, entrepreneurial spirit, and individual responsibility among employees. Employee initiatives have led to continuous process improvements, resulting in considerable operating efficiencies and quality control, as well as the maintenance of a safe and comfortable working environment. The Company believes that a lack of job titles and direct formal reporting responsibilities eliminates perceived barriers to advancement and reduces the potential for adversarial relationships to arise within the organization. A workplace without walls in the Company’s offices as well as on the shop floor encourages informal employee consultation and provides the opportunity for all personnel to interface across functional areas.
Leverage Manufacturing Capability and Know-how as Competitive Advantages. The Company believes that one of its competitive advantages is its ability to consistently manufacture products to demanding specifications. The Company’s strong process capability is critical in achieving the high performance characteristics of its screw-in cartridge valves. The Company has the ability to manufacture most of the components of its products with the exception of springs, elastomer seals, and electrical coils, although most high-volume machining is performed by independent, outside vendors (see Manufacturing). The Company has in-house heat treatment capability to provide consistent and reliable control of this critical operation.
Sell Through Distributors. Due to the variety of potential customers and the Company’s desire to avoid unnecessary bureaucracy, the sales function has been performed primarily by independent distributors. The Company has 66 distributors, 44 of which are located outside the United States, and a majority of which have strong technical backgrounds or capabilities, which enable them to develop practical, efficient and cost-effective fluid power systems for their customers. Many of these distributors sell products manufactured by other companies that allow them to provide a complete hydraulic system to the customer. The Company provides a high level of technical support to its distributors through open access to the Company’s engineering staff, technical documentation, and technical training programs.
Develop Closer Relations with Key Customers. The Company maintains close relationships with many OEMs and end users of its products to help it understand and predict future needs for fluid power control devices and to test and refine new product offerings. The Company also recognizes it will sometimes have to develop a direct relationship in the areas of sales and support with some large OEMs that are existing or potential customers. The Company will be selective in developing these relationships and believes the closer ties will help increase sales without compromising profits or developing excessive bureaucracy.
Brand Label and License Manufacturing where desirable. When it is deemed to be of strategic benefit, the Company sometimes enters into marketing, brand labeling and/or non-exclusive manufacturing licensing agreements with other manufacturers of fluid power components. Historically, approximately 5% of the Company’s sales have been to other fluid power manufacturers that incorporate the Company’s products into complete system solutions.
Products
Screw-in Cartridge Valves
The Company designs and manufactures high-performance, screw-in hydraulic cartridge valves in five size ranges, suitable for flows from one to 400 gallons per minute and continuous operating pressures up to 5,000 pounds per square inch. The floating construction pioneered by the Company provides demonstrable performance and reliability advantages compared to most competitors’ product offerings due to its self-alignment characteristic that accommodates potential manufacturing deviations common in the thread-making operations of screw-in cartridge valves and manifolds. This floating construction

Table of Contents

significantly differentiates the Company from most of its competitors, which design and manufacture rigid screw-in cartridge valves that fit an industry common cavity. The floating construction of the Company’s screw-in cartridge valves eliminates the tendency of working parts inside the cartridge valves to bind when screwed into the manifold, which leads to unnecessary stress and, often, premature failure. Some competitors manufacture products that fit the Company’s cavity. Strategically, the Company believes the markets for its products will expand more rapidly if other sources are available for products that fit the Company’s cavity.
Manifolds
A manifold is a solid block of metal, usually aluminum or ductile iron, which is machined to create threaded cavities and channels into which screw-in cartridge valves can be installed and through which the hydraulic fluid flows. The manifolds manufactured by the Company are described below:
Standard Manifolds. The variety of standard, catalogued manifolds offered by the Company is unmatched by any screw-in cartridge valve or manifold competitor. These products allow customers to easily integrate the Company’s screw-in cartridge valves into their systems in many different ways. Once designed, standard manifolds require minimal, if any, maintenance engineering over the life of the product and can be readily manufactured at all of the Company’s operations.
Custom Manifolds. Custom manifolds are designed for a customer-specific application and typically combine many different screw-in cartridge valves in a single package or multiple packages. The Company’s internally-developed, proprietary expert system software allows the Company to manufacture manifolds efficiently in low volumes. The innovative design of the Company’s screw-in cartridge valves allows manifolds to be physically smaller for certain applications than functionally similar manifolds containing competitors’ screw-in cartridges that fit industry common cavities. The Company believes many of the custom manifolds that incorporate cartridge valves which fit industry common cavities require testing after assembly. The Company does not routinely test manifolds that contain its screw-in cartridge valves because of the inherent reliability of the cartridge valves, and this provides the Company with a significant competitive advantage. Custom manifolds provide many benefits to end users and equipment manufacturers, including reduced assembly time, order simplification, reduced leakage points, neater packaging, potentially fewer hose and fitting connections, and more control functions in a single location.
Engineering
The Company’s engineers play an important role in all aspects of the Company’s business, including design, manufacturing, sales and marketing and technical support. When designing products, engineers work within a disciplined set of design parameters that often results in repeated incorporation of existing screw-in cartridge valve parts in new functional products.
During product development, engineers work closely with manufacturing personnel to define the processes required to manufacture the product reliably and consistently. The close link between engineering and manufacturing helps smooth the transition from design to market. Design changes to facilitate manufacturing processes are sometimes considered but typically not if product performance levels would be compromised. The Company practices a continuous improvement process, which it believes is largely attributable to its horizontal management structure that empowers employees and encourages their creative contribution. At various times the Company may incorporate design changes in a product to improve its performance or life expectancy. All of the Company’s engineers provide application support to customers and distributors.
Manufacturing
The Company is a process intensive manufacturing operation that extensively utilizes computer numerically controlled (“CNC”) machinery to manufacture its products. Where commercial machinery is not available for specific manufacturing or assembly operations, the Company often designs and builds its own machinery to perform these tasks. The Company makes extensive use of automated handling and assembly technology (including robotics) where possible to perform repetitive tasks, thus promoting manufacturing efficiencies and workplace safety. The Company has its own electric heat treatment furnaces to provide consistent and reliable control of this important operation.

At its two Sarasota, Florida, manufacturing plants, the Company has extensive testing facilities that allow its design engineers to test fully all cartridge valve products at their maximum rated pressure and flow rates. A metallurgist and complete metallurgical laboratory support the Company’s design engineers and in-house heat treatment. The resident engineers at the Company’s other facilities also utilize test equipment.
The Company employs a build-to-order philosophy and relies on its distributors to purchase and maintain sufficient inventory to meet their customers’ demands. With this build-to-order philosophy, most raw materials, including aluminum and steel, are delivered on a just-in-time basis. These and other raw materials are commercially available from multiple sources.
The Company controls most critical finishing processes in-house but does rely on a small network of outside manufacturers to machine cartridge parts to varying degrees of completeness. Many high-volume machining operations are performed exclusively at outside suppliers. The Company is very selective in establishing its supplier base and attempts to develop and maintain long-term relationships with suppliers. The Company continually reviews all of its suppliers to improve the quality of incoming parts and to assess opportunities for better control of both price and quality. The Company’s quality systems at the U.S. and U.K. facilities are in compliance with ISO 9001:2000 for design and manufacture of steel cartridge valves, aluminum and ferrous manifolds for hydraulic systems. Those in Korea are certified to ISO 9001:2000 and 14001:1996 for the design, development, production, and after sales service of hydraulic valves.
Sales and Marketing
The Company’s products are sold globally, primarily through independent fluid power distributors. Distributors are supported with product education programs conducted by the Company at its facilities. Technical support is provided by each of the Company’s operations (Florida, Kansas, England, Germany, France, Korea, and China). Included in the Company’s sales and marketing staff are hydraulic engineers who have significant experience in the fluid power industry. Discount pricing structures encourage distributors to buy in moderate to high volumes to ensure there is a local inventory of products in the marketplace.
The Company currently has 66 distributors, 44 of which are located outside the United States and a majority of which have strong technical backgrounds or capabilities, which enable them to develop practical, efficient, and cost-effective fluid power systems for their customers. In 2005, sales to the Company’s largest distributor represented less than 7% of net sales and net sales outside of the United States represented approximately 50% of total net sales.
In addition to distributors, the Company sells directly to other companies within the hydraulic industry under a pricing program that does not undermine the primary distributors’ efforts. Companies that participate in this program utilize the Company’s products in a value-added application, integrating the Company’s screw-in cartridge valves into other fluid power products or systems of their manufacture. Management believes this strategy strengthens the Company by encouraging other manufacturers to buy products from the Company that they might otherwise develop themselves.
The Company has in the past, to a limited degree, sold product directly to OEMs. Although the Company does not have any employee whose primary responsibility is direct sales, it may consider this in the future. The Company recognizes that to gain access to certain large OEM accounts it may have to deal directly in the areas of sales and support.
While the Company principally sells its products through distributors, it provides end users with technical information via its website and catalogues that offers design engineers all of the information necessary to specify and obtain the Company’s products. The Company believes that providing complete technical information to the marketplace helps to stimulate demand for the Company’s products. The Company’s website continues to evolve and has helped to drastically reduce the time between engineering release of products and their appearance in the marketplace. The Company is continuing to invest in this technology as one of the best ways to keep its broad product offering available to customers around the world.

Customers
While many of the Company’s customers’ requirements are growing, management does not believe that the loss of any one customer would have a material adverse effect on the Company’s business. End-user customers are classified by whether their primary applications for the Company’s products are “mobile” or “industrial.”
Mobile applications involve equipment that generally is not fixed in place and is often operated in an uncontrolled environment, such as construction, agricultural, mining, and fire and rescue and other utility equipment. Mobile customers were the original users of screw-in cartridge valves due to the premium that these industries place on considerations of space, weight, and cost. Mobile customers historically account for approximately 66% of the Company’s net sales.
Industrial applications involve equipment that generally is fixed in place in a controlled environment. Examples include automation machinery, presses, plastics machinery such as injection molding equipment, and machine tools. The requirements of the industrial marketplace are more demanding than most mobile applications since industrial equipment typically operates at significantly higher cycles. The Company’s products are designed to withstand these operating imperatives, and industrial applications historically account for approximately 34% of the Company’s net sales. Many conventional valve designs are still used in industrial applications and represent substitution opportunities for the Company’s products.
The Company does not warrant its products for use in any of the following applications, (i) any product that comes under the Federal Highway Safety Act, such as steering or braking systems for passenger-carrying vehicles or on-highway trucks, (ii) aircraft or space vehicles, (iii) ordnance equipment, (iv) life support equipment, and (v) any product that, when sold, would be subject to the rules and regulations of the United States Nuclear Regulatory Commission. These “application limitations” have alleviated the need for the Company to maintain the internal bureaucracy necessary to conduct business in these market segments.
Competition
The hydraulic valve industry is highly fragmented and intensely competitive. The Company has a large number of competitors, some of which are full-line producers and others that are niche suppliers similar to the Company. Most competitors market globally. Full-line producers have the ability to provide total hydraulic systems to customers, including components functionally similar to those manufactured by the Company. There has been increasing consolidation activity within the industry in recent years, with large, full-line producers filling out their product lines by acquiring or entering into relationships with other hydraulics companies, and management expects there will be further consolidation in the future. The Company believes that it competes based upon quality, reliability, price, value, speed of delivery and technological characteristics.
Most of the Company’s screw-in cartridge valve competitors produce screw-in cartridge valves that fit an industry common cavity that sometimes allows their products to be interchangeable. The industry common cavity is not currently supported by any national or global standards organizations, although there is an ongoing effort to standardize a modified version of this cavity in the United States. The International Standards Organization (ISO) has developed a standard screw-in cartridge cavity that is different from the industry common cavity, but the Company is not aware of any major competitor that currently produces a full line of standard products conforming to the ISO standard. The Company does not manufacture a product that fits either the industry common or the ISO standard cavity. Some competitors manufacture selected screw-in cartridge valves that fit the Company’s cavity. The Company believes the majority of these products are load control valves. Management believes that increased use of the Company’s cavity will be beneficial in the long term because, although competition will increase, markets and applications for the Company’s products also will increase.
Employees
As of December 31, 2005, the Company had 597 full-time employees in the United States, 74 in England, 32 in Germany, one in France and 33 in Korea. The Company continues to focus its efforts on designing and manufacturing standard products, allowing it to maintain over 90% of its employees in manufacturing, distribution, and engineering functions. No employees are represented by a union in any of the Company’s operating units, and management believes that relations with its employees are good.

Table of Contents

Employees are paid either hourly or with an annual salary at rates that are competitive with other companies in the industry and in its geographic areas. Management believes that the combination of competitive salary, above average health and retirement plans, and a safe and pleasant working environment discourages employee turnover and encourages efficient, high-quality production. Nevertheless, due to the nature of the Company’s manufacturing business, it is often difficult to attract skilled personnel.
Patents and Trademarks
The Company believes that the growth of its business is dependent upon the quality and functional performance of its products and its relationship with the marketplace, rather than the extent of its patents and trademarks. The Company’s principal trademark is registered internationally in the following countries: Argentina, Australia, Brazil, Canada, Chile, China, France, Germany, India, Italy, Japan, Korea, Mexico, Peru, Spain, Sweden, Switzerland, the United Kingdom and the United States. While the Company believes that its patents have significant value, the loss of any single patent would not have a material adverse effect on the Company.

ITEM 1.A. — RISK FACTORS
FACTORS INFLUENCING FUTURE RESULTS - FORWARD - LOOKING STATEMENTS
This Annual Report contains "forward-looking statements" (within the meaning of the Private Securities Litigation Reform Act of 1995) that are based on current expectations, estimates, forecasts, and projections about us, our beliefs, and assumptions made by us, including (i) our strategies regarding growth, including our intention to develop new products; (ii) our financing plans; (iii) trends affecting our financial condition or results of operations; (iv) our ability to continue to control costs and to meet our liquidity and other financing needs; (v) the declaration and payment of dividends; and (vi) our ability to respond to changes in customer demand domestically and internationally, including as a result of standardization. In addition, we may make other written or oral statements, which constitute forward-looking statements, from time to time. Words such as “may,” “expects,” “projects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” variations of such words, and similar expressions are intended to identify such forward-looking statements. Similarly, statements that describe our future plans, objectives or goals also are forward-looking statements. These statements are not guarantees of future performance and are subject to a number of risks and uncertainties, including those discussed below and elsewhere in this report. Our actual results may differ materially from what is expressed or forecasted in such forward-looking statements, and undue reliance should not be placed on such statements. All forward-looking statements are made as of the date hereof, and we undertake no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise.

Factors that could cause actual results to differ materially from what is expressed or forecasted in such forward-looking statements include, but are not limited to: (i) conditions in the capital markets, including the interest rate environment and the availability of capital; (ii) changes in the competitive marketplace that could affect our revenue and/or cost bases, such as increased competition, lack of qualified engineering, marketing, management or other personnel, and increased labor and raw materials costs; (iii) new product introductions, product sales mix and the geographic mix of sales nationally and internationally; and the following risk factors:
Sales in our industry are subject to economic cycles. The capital goods industry in general, and the hydraulic valve and manifold industry in particular, are subject to economic cycles, which directly affect customer orders, lead times and sales volume. The downturn in the industry from 2001 — 2003 had a material adverse effect on our business and results of operations. The strength of the economic recovery in 2004 and 2005 has and will continue to directly affect orders for our products.
Our products are subject to obsolescence due to technological change. The fluid power industry and its component parts are subject to technological change, evolving industry standards, changing customer requirements and improvements in and expansion of product offerings. If technologies or standards used in our products become obsolete, our business, financial condition and results of operations will be adversely affected. Although we believe that we have the technological capabilities to remain competitive, we cannot assure you that developments by others will not render our products or technologies obsolete or noncompetitive. See “Item 1 — Business — Strategy.”
We are subject to intense competition. The hydraulic valve industry is highly fragmented and intensely competitive, and we face competition from a large number of competitors, some of which are full-line producers and others that are niche suppliers like us. Full-line producers have the ability to provide total hydraulic systems to customers, including components functionally similar to those manufactured by us. We believe that we compete based upon quality, reliability, price, value, speed of delivery and technological characteristics. Many of our screw-in cartridge valve competitors are owned by corporations that are significantly larger than us and have greater financial resources than we do. We cannot assure you that we will continue to be able to compete effectively with these companies.
The manifold business is also highly fragmented and intensely competitive. All of the major screw-in cartridge valve manufacturers either manufacture manifolds or have sources that they use on a regular basis. In addition, there are a number of independent manifold suppliers that produce manifolds incorporating various manufacturers’ screw-in cartridge valves, including those made by us. Finally, there are many small, independent machine shops that produce manifolds at very competitive prices. We believe that competition in the manifold business is based upon quality, price, proximity to the customer

Table of Contents

and speed of delivery. Many of our competitors have very low overhead structures and we cannot assure you that we will continue to be able to compete effectively with these companies.
In addition, we compete in the sale of hydraulic valves and manifolds with certain of our customers. Generally, these customers purchase cartridge valves from us to meet a specific need in a system that cannot be filled by any valve made by such customer. To the extent that we introduce new valves in the future that increase the competition between us and such customers, such competition could adversely affect our relationships with these customers.
The marketplace could adopt an industry standard cavity that would not accommodate our products. Our screw-in cartridge valves fit into a unique cavity for which, to date, few other manufacturers have designed products. Accordingly, our screw-in cartridge valves are not interchangeable with those of other manufacturers. Most competitive manufacturers produce screw-in cartridge valves that fit into an industry common cavity. There is an ongoing effort in the United States to produce a new standard for screw-in hydraulic cartridge valve cavities based on the industry common cavity. Additionally, the International Standards Organization (“ISO”) has an existing industry standard for screw-in hydraulic cartridge valve cavities, which is different from our cavity and the industry common cavity. In our view, the industry common cavity as well as the suggested standardized form of this cavity and the ISO standard cavity fail to address critical functional requirements, which could result in performance and safety problems of significant magnitude for end users. To our knowledge, no major competitor has converted its standard product line to fit the ISO standard cavity. Any move by a substantial number of screw-in cartridge valve and manifold manufacturers toward the adoption of ISO standard or another standard, based on the existing industry common cavity, could have a material adverse effect on our business, financial condition and results of operation. See “Item 1. — Business — Competition.”
We are subject to risks relating to international sales. In 2005, approximately 50% of our net sales were outside of the United States. We are expanding the scope of our operations outside the United States, both through direct investment and distribution, and expect that international sales will continue to account for a substantial portion of our net sales in future periods. International sales are subject to various risks, including unexpected changes in regulatory requirements and tariffs, longer payment cycles, difficulties in receivable collections, potentially adverse tax consequences, trade or currency restrictions, and, particularly in emerging economies, potential political and economic instability and regional conflicts. Furthermore, our international operations generate sales in a number of foreign currencies, particularly British pounds, the Euro, and the Korean Won. Therefore, our financial condition and results of operation are affected by fluctuations in exchange rates between the United States dollar and these currencies. Any or all of these factors could have a material adverse effect on our business, financial condition and results of operations.
We are subject to various risks relating to our growth strategy. In pursuing our growth strategy, we intend to expand our presence in our existing markets and enter new markets. In addition, we may pursue acquisitions and joint ventures to complement our business. Many of the expenses arising from our expansion efforts may have a negative effect on operating results until such time, if at all, that these expenses are offset by increased revenues. We cannot assure you that we will be able to improve our market share or profitability, recover our expenditures, or successfully implement our growth strategy. See “Item 1 — Business — Strategy.”
Our expansion strategy also may require substantial capital investment for the construction of new facilities and their effective operation. We may finance the acquisition of additional assets using cash from operations, bank or institutional borrowings, or through the issuance of debt or equity securities. We cannot assure you that we will be able to obtain financing from bank or institutional sources or through the equity or debt markets or that, if available, such financing will be on terms acceptable to us.
We are dependent upon key employees and skilled personnel. Our success depends, to a significant extent, upon a number of key individuals. The loss of the services of one or more of these individuals could have a material adverse effect on our business. Our future operating results depend to a significant degree upon the continued contribution of our key technical personnel and skilled labor force. Competition for management and engineering personnel is intense, and we compete for qualified personnel with numerous other employers, some of which have greater financial and other resources than

we do. We conduct a substantial part of our operations at our facilities in Sarasota, Florida. Our continued success depends on our ability to attract and retain a skilled labor force at this location. While we have been successful in attracting and retaining skilled employees in the past, we cannot assure you that we will continue to be successful in attracting and retaining the personnel we require to develop, manufacture and market our products and expand our operations. See “Item 1 — Business — Employees.”
We are subject to the risk of liability for defective products. The application of many of our products entails an inherent risk of product liability. We cannot assure you that we will not face any material product liability claims in the future or that the product liability insurance we maintain at such time will be adequate to cover such claims.
We are subject to fluctuations in the prices of raw materials. The primary raw materials used in the manufacture of our products are aluminum, ductile iron and steel. We cannot assure you that prices for such materials will not increase or, if they do, that we will be able to increase the prices for our products to maintain our profit margins. Material costs have increased during the past fiscal year and are predicted to increase further. In January 2006, we initiated modest price increases on selected products; if the price increases do not adequately cover material cost increases, our operating results may be adversely affected.
We are dependent upon our parts suppliers. Our largest expense in the cost of sales is purchased cartridge valve parts. We cannot assure you that our manufacturing costs and output would not be materially and adversely affected by operational or financial difficulties experienced by one or more of our suppliers.
We are subject to the cost of environmental compliance and the risk of failing to comply with environmental laws. Our operations involve the handling and use of substances that are subject to federal, state and local environmental laws and regulations that impose limitations on the discharge of pollutants into the soil, air and water and establish standards for their storage and disposal. We believe that our current operations are in substantial compliance with applicable environmental laws and regulations, the violation of which could have a material adverse effect on our business, financial condition and results of operations. New laws and regulations, or stricter interpretations of existing laws or regulations, could have a material adverse affect on our business, financial condition and results of operations.
Our board may decide to reduce or eliminate dividends. Although we have paid a cash dividend each quarter since our common stock began trading in 1997, we cannot assure you that funds will be available for this purpose in the future. The declaration and payment of dividends is subject to the sole discretion of our board of directors and will depend upon our profitability, financial condition, capital needs, future prospects and other factors deemed relevant by the board, and may be restricted by the terms of credit agreements that we may enter into.
Certain anti-takeover provisions may hinder or prevent a change in control. Our Articles of Incorporation provide for a classified board of directors. In addition, the Articles give the board of directors the authority, without further action by the shareholders, to issue and fix the rights and preferences of a new class, or classes, of preferred stock. These and other provisions of the Articles and our Bylaws may deter or delay changes in control, including transactions in which shareholders might otherwise receive a premium for their shares over then current market prices. In addition, these provisions may limit the ability of shareholders to approve transactions that they may deem to be in their best interests.
We are subject to control by certain shareholders and management. Members of the Koski family, including two Directors, Robert E. Koski, our founder and former Chairman, and Christine L. Koski, and their affiliates own or control approximately 32% of the outstanding shares of our common stock. Accordingly, the members of the Koski family have the ability to influence significantly the election of our directors and the outcome of certain corporate actions requiring shareholder approval, and to influence our business. Such influence could preclude any acquisition of the Company and could adversely affect the price of our common stock. Our directors and executive officers as a group beneficially own or control

approximately 34% of the outstanding shares of our common stock. See “Item 12. — Security Ownership of Certain Beneficial Owners and Management.”
ITEM 2. PROPERTIES
The Company owns major facilities in the United States, United Kingdom, Germany, and Korea, as set forth below.
The Company owns a 66,000 square foot facility in Sarasota, Florida, which houses manufacturing, design, marketing and other administrative functions. The Sarasota facility is well suited for the design, testing and manufacture of the Company’s products.
The Company also owns a 77,000 square foot manufacturing facility in Manatee County, Florida. The Manatee County facility, constructed in 1997, has a productive capacity similar to the Sarasota facility.
The close proximity of the Florida facilities allows for quick change and the ability to shift resources, including machinery and people, to effectively meet changing business requirements.
Both facilities in Florida are encumbered by a revolving line of credit, which is due August 1, 2011. Monthly payment of interest only is due on the revolving line of credit, with a variable interest rate of LIBOR + 1.5% or the Bank’s Base Rate, at the Company’s discretion. At December 31, 2005, the Line of Credit had an outstanding balance of $1.0 million.
The Company also owns vacant land in Manatee County, Florida, for future expansion requirements. There is no mortgage on this property and the Company believes the land to be well suited to add over 30,000 square feet of manufacturing capacity.
The Company leases a 17,000 square foot manufacturing facility in Lenexa, Kansas, which is used to manufacture manifolds for the North American market.
The Company owns a 37,000 square foot facility in Coventry, England, free of any encumbrances. The facility, while primarily acting as a distributor, is also involved in cartridge assembly and manifold manufacturing.
The Company’s 45,000 square foot distribution and manufacturing facility in Erkelenz, Germany is encumbered by a mortgage loan, which is due September 30, 2008, and has a fixed interest rate of 6.05%. At December 31, 2005, the principal balance was $0.6 million. This facility is well suited to house equipment used for manufacturing and testing of the Company’s products. Currently, a small portion of the manufacturing area is utilized and the remainder is leased on an annual basis to an outside company.
The Company owns a 10,000 square foot distribution and manufacturing facility in Inchon, Korea, free of any encumbrances.
The Company believes that its properties have been adequately maintained, are generally in good condition, and are suitable and adequate for its business as presently conducted. The extent of utilization of the Company’s properties varies from time to time and among its facilities.
ITEM 3. LEGAL PROCEEDINGS
The Company from time to time is involved in routine litigation incidental to the conduct of its business. The Company does not believe that any pending litigation will have a material adverse effect on its consolidated financial position or results of operations.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
OVERVIEW
Sun Hydraulics Corporation is a leading designer and manufacturer of high-performance screw-in hydraulic cartridge valves and manifolds, which control force, speed and motion as integral components in fluid power systems. The Company sells its products globally through wholly owned subsidiaries and independent distributors. Sales outside the United States for the year ended December 31, 2005, were approximately 50% of total net sales.
Approximately 66% of product sales are used by the mobile market, which is characterized by applications where the equipment is not fixed in place, the operating environment is often unpredictable, and duty cycles are generally moderate to low. Some examples of mobile equipment include off-road construction equipment, fire and rescue equipment and mining machinery.
The remaining 34% of sales are used by industrial markets, which are characterized by equipment that is fixed in place, typically in a controlled environment, and which operates at higher pressures and duty cycles. Automation machinery, metal cutting machine tools and plastics machinery are some examples of industrial equipment. The Company sells to both markets with a single product line.
Company Focus
Since the capital goods rebound began in late 2003, the Company has realized robust growth in all areas of the world. Management believes there are five key reasons why:
    Delivery performance,
 
    New products, especially electro-hydraulic products,
 
    Integrated packages,
 
    Our geographic presence, and
 
    Our website.
During the difficult times of 2001 and 2002, the Company kept its workforce fully intact, despite a severe decline in business. Manufacturing personnel reviewed and improved many processes to increase productivity. Existing products were redesigned to make them easier to manufacture. And many new products were released to complement what Management feels is the most extensive cartridge valve line in the world.
Many of the Company’s new products are electrically actuated cartridges, including solenoid and proportional valves. The new electrically actuated cartridges allowed new system opportunities by offering complete valve packages which could not be offered previously. This product line expansion allows integrated packages to be designed with 100% Sun content.
To support this effort, the Company has wholly-owned companies in North America, Europe and the Far East, augmented by what management believes to be the finest distribution network in the fluid power industry. The Company’s distributors know how to apply products and develop integrated solutions for the local market.
To tell the marketplace about all of these developments, the Company relies on www.sunhydraulics.com. The Company’s website is developed for serious design engineers. It provides all the detailed technical information and specifications to select, apply and obtain Sun products, 24 hours a day, seven days a week.
Industry Conditions
Demand for the Company’s products is dependent on demand for the capital goods into which the products are incorporated. The capital goods industries in general, and the fluid power industry specifically, are subject to economic cycles. According to the National Fluid Power Association (the fluid

16


Table of Contents

power industry’s trade association in the United States), the United States index of shipments of hydraulic products increased 13% and 25% in 2005 and 2004, respectively, after a decrease of 2% in 2003.
The Company’s order trend has historically tracked closely to the United States Purchasing Managers Index (PMI). The index was 55.6 at the end of December 2005 compared to 57.3 at the end of December 2004. When the PMI is over 50, it indicates economic expansion.

Sales in 2005 were up 24%, following 33% growth in 2004. The Company grew in all geographic segments gaining market share. The Company is pleased with this year’s results and looks forward to 2006.
Order rates accelerated going into the new year, and have continued throughout the first quarter with run rates up over 28%. Capacity in the Company’s U.S. manufacturing facilities continues to increase as it refines production processes and adds new machinery. Shipping on time to its customers is still the Company’s main focus, and remains one of the keys to its success.
Sarbanes-Oxley
Sun completed documentation and testing for 2005 related to compliance with Sarbanes-Oxley, Section 404. The Company is pleased that the first year of SOX is behind it. The Company’s goal throughout the project was to comply fully with the law, contain project costs, and keep the disruption of the exercise on work flow to a minimum. The Company was able to accomplish this in year one and expects that it will do the same in year two.
Dividends
The Company declared quarterly dividends of $0.05, $0.05, $0.10, and $0.10 per share to shareholders of record on the last day of the first, second, third, and fourth quarters of 2005, respectively. These dividends were paid on the 15th day of each month following the date of declaration. Total dividends of $0.30 were paid to shareholders in 2005. In addition, the Company declared a three-for-two stock split, effected in the form of a 50% stock dividend, to shareholders of record on June 30, 2005, which was paid on July 15, 2005.
Cash Flow
Net cash generated from operations for the year was $17.0 million, a $2.3 million increase compared to $14.7 million in 2004. Capital expenditures for the year were $8.8 million, cash on hand decreased $3.9

Outlook for 2006
2006 first quarter sales are estimated to be $34 million, a 21% increase over last year on a calendarized basis. First quarter earnings per share are estimated to be between $0.35 and $0.37 per share, compared to $0.32 per share last year.
Comparison of Years Ended December 31, 2005 and December 25, 2004
Net Sales
Net sales were $116.8 million, an increase of $22.3 million, or 23.5%, compared to $94.5 million in 2004. Net sales increased 21% excluding the effect of exchange rates.
Net sales in the United States operation increased 23.7% with shipments to Asia up 14.0%, Canada up 38.1% and domestic shipments up 23.0%. Net sales in the United Kingdom operation increased 20.0%, primarily due to increases in domestic sales and sales to European distributors. German operation net sales increased 20.3%, with significant increases in domestic sales and sales to Italy, Switzerland and Austria. Net sales in the Korean operation increased 33.0%, due to increased domestic sales in Korea and sales to China.

Gross Profit
Gross profit increased 29.4% to $36.9 million in 2005, compared to $28.5 million in 2004. Gross profit as a percentage of net sales increased to 31.6% in 2005, compared to 30.2% in 2004. A moderate and selective sales price increase in January this year, coupled with increased sales volume and improved productivity, more than offset the increased cost of materials and labor.
Selling, Engineering, and Administrative Expenses
Selling, engineering and administrative expenses in 2005 were $17.7 million, a $1.5 million, or 9.2%, increase, compared to $16.2 million in 2004. The increase was primarily due to increased audit and contract labor fees related to 2005, including Sarbanes-Oxley 404 compliance, personnel related expenses, foreign compensation expense, a write-off of the remaining deferred loan costs related to the extinguishment of debt and costs for a bi-annual European trade show.
Interest Expense
Interest expense was $0.4 million and $0.5 million in 2005 and 2004, respectively. While average outstanding debt decreased $7.9 million, from $15.2 million in 2004 to $7.3 million in 2005, the average interest rate on variable debt increased from the period ended December 25, 2004, due to an increase in the LIBOR rate.
Foreign Currency Transaction (Gain) Loss
Foreign currency transaction gain in 2005 was $0.4 million, compared to a minimal impact on net income in 2004. The gain was primarily a result of the revaluation of United Kingdom balance sheet items which were held in U.S. dollars.
Miscellaneous (Income) Expense
Miscellaneous (income) expense had a minimal impact on net income in 2005 and 2004.
Income Taxes
The provision for income taxes for the year ended December 31, 2005, was 33.1% of pretax income compared to 33.3% for the year ended December 25, 2004. The decrease was due to a change in the relative levels of income and different tax rates in effect among the countries in which the Company sells its products.
Comparison of Years Ended December 25, 2004 and December 27, 2003
Net Sales
Net sales in 2004 were $94.5 million, an increase of $23.7 million, or 33.5%, compared to $70.8 million in 2003. Net sales increased 29% excluding the effect of exchange rates.
Net sales in the United States operation increased 37.5% with shipments to Asia up 29.3%, Canada up 27.3% and domestic shipments up 40.2%. Net sales in the United Kingdom operation increased 17.9%, primarily due to increases in sales to European distributors, while domestic sales were flat. German operation net sales increased 38.1%, with increases in all markets served. Net sales in the Korean operation increased 27.2%, due to increased shipments stimulated by Korean customers meeting demand from China coupled with growth in domestic Korean business.
Gross Profit
Gross profit increased 54.4% to $28.5 million in 2004, compared to $18.5 million in 2003. Gross profit as a percentage of net sales increased to 30.2% in 2004, compared to 26.1% in 2003. The increase in gross profit as a percentage of net sales was due to the increase in net sales and productivity improvements, which more than offset increased material and employee benefit costs.

Selling, Engineering, and Administrative Expenses
Selling, engineering and administrative expenses in 2004 were $16.2 million, a $1.4 million, or 9.7%, increase, compared to $14.8 million in 2003. The increase was primarily due to higher employee wages and benefit costs of $1.1 million including the establishment of an ESOP, and higher advertising costs including catalogs and website updates of $0.2 million.
Interest Expense
Interest expense was $0.5 million and $0.6 million in 2004 and 2003, respectively. While average outstanding debt increased $1.3 million, from $13.9 million in 2003 to $15.2 million in 2004, due to debt acquisitions related to the $2 per share special dividend paid on August 18, 2003, lower interest rates were negotiated on the new debt allowing interest expense to decrease.
Foreign Currency Transaction (Gain) Loss
There was minimal impact to net income from foreign currency transactions in 2004 compared to a foreign currency gain of $0.1 million in 2003, due primarily to gains in the Euro and Korean Won against the U.S. dollar. While the Euro, the Korean Won and the British Pound made gains against the U.S. dollar in 2004, the U.K. operations experienced losses related to sales conducted in U.S. dollars.
Miscellaneous (Income) Expense
Miscellaneous income had a minimal impact on net income in 2004, compared to miscellaneous income of $0.1 million in 2003. The $0.1 million decrease was due to losses on disposal of fixed assets and increased charitable contributions, both in the U.S. operations.
Income Taxes
The provision for income taxes for the year ended December 25, 2004, was 33.3% of pretax income compared to 33.6% for the year ended December 27, 2003. The decrease was due to a change in the relative levels of income and different tax rates in effect among the countries in which the Company sells its products.
Liquidity and Capital Resources
Historically, the Company’s primary source of capital has been cash generated from operations, although short-term fluctuations in working capital requirements have been met through borrowings under revolving lines of credit as needed. The Company’s principal uses of cash have been to pay operating expenses, pay dividends to shareholders, make capital expenditures, and service debt.
Net cash flow from operations in 2005 was $17.0 million, compared to $14.7 million in 2004 and $9.5 million in 2003. The $2.3 million increase in the Company’s net cash flow from operations in 2005 was due primarily to the increase in net income of $5.0 million, which was partially offset by increases in tax assets, decreases in tax liabilities, and a decrease in accrued expenses and other liabilities. Cash on hand decreased $3.9 million from $9.8 million in 2004 to $5.8 million in 2005. Days sales outstanding increased slightly from 33 to 36 in 2005 and inventory turns improved from 9.6 to 10.1. The increase in the Company’s net cash flow from operations in 2004, compared to 2003 was due primarily to the increase in net income of $5.7 million, while working capital excluding cash remained relatively static.
Capital expenditures, consisting primarily of purchases of machinery and equipment, were $8.8 million in 2005, compared to $5.0 million in 2004 and $3.1 million in 2003. Capital expenditures in 2006 are projected to be $9.0 million.
On August 11, 2005, the Company completed a refinancing of its existing debt in the U.S. with Fifth Third Bank (the “Bank”). The new financing consists of a secured revolving line of credit of $35 million. (the “Line of Credit”). The Line of Credit is secured by the Company’s U.S. assets, including its manufacturing facilities, and requires monthly payments of interest. The Line of Credit has a floating interest rate for the first year of 1) 1.5% over the 30-day LIBOR Rate (as defined), or 2) the Bank’s Base Rate (as defined), at

the Company’s discretion. Thereafter, the interest rate will vary based upon the Company’s leverage ratio. The Line of Credit is payable in full on August 1, 2011, but maturity may be accelerated by the Bank upon an Event of Default (as defined). Prepayment may be made without penalty or premium at any time upon the required notice to the Bank. At December 31, 2005, the Line of Credit had an outstanding balance of $1.0 million.
The Line of Credit is subject to debt covenants including: 1) Debt (as defined) to Tangible Net Worth (as defined) ratio of not more than 1.5:1.0, 2) Funded Debt (as defined) to EBITDA (as defined) ratio of not more than 2.5:1.0, and 3) EBIT (as defined) to Interest Expense (as defined) ratio of not less than 1.1:1.0; and requires the Company to maintain its primary domestic deposit accounts with the Bank. As of December 31, 2005, the Company was in compliance with all debt covenants.
The Company declared the following quarterly dividends to shareholders of record on the last day of the respective quarter:
                         
    2005   2004   2003
First quarter
  $ 0.050     $ 0.027     $ 0.027  
Second quarter
    0.050       0.033       0.027  
Third quarter
    0.100       0.033       0.027  
Fourth quarter
    0.100       0.050       0.027  
These dividends were paid on the 15th day of each month following the date of declaration. In addition, the Company declared a 50% stock dividend on June 30, 2005, and paid a special dividend of $1.33 per share totaling $13.3 million on August 18, 2003.
The declaration and payment of future dividends is subject to the sole discretion of the Board of Directors, and any determination as to the payment of future dividends will depend upon the Company’s profitability, financial condition, capital needs, future prospects and other factors deemed pertinent by the Board of Directors.
The Company believes that cash generated from operations and its borrowing availability under the revolving Line of Credit will be sufficient to satisfy the Company’s operating expenses and capital expenditures for the foreseeable future. In the event that economic conditions were to severely worsen for a protracted period of time, the Company would have several options available to ensure liquidity in addition to increased borrowing. Capital expenditures could be postponed since they primarily pertain to long-term improvements in operations. Additional operating expense reductions also could be made. Finally, the dividend to shareholders could be reduced or suspended.
In December 2005, the Company’s Board of Directors authorized the repurchase of up to $2.0 million of Company stock, to be completed no later than January 15, 2007. The stock purchases will be made in the open market or through privately negotiated transactions. Market purchases will be made subject to restrictions relating to volume, price and timing in an effort to minimize the impact of the purchases on the market for the Company’s securities. The amount of the stock repurchases was set based upon the anticipated number of shares that will be required to fund the Company’s ESOP, and employee stock purchase plan, through fiscal year 2006. As of December 31, 2005, the Company had repurchased 82,500 shares on the open market at an average cost of $18.87 per share. Of the 82,500 shares purchased, 65,000 were retired prior to December 31, 2005.
Subsequent to December 31, 2005, the Company repurchased 12,700 shares on the open market at an average cost of $19.16 per share. Total purchases under the plan have amounted to $1.8 million.
In June 2004, the Company’s Board of Directors authorized the repurchase of approximately $0.4 million of outstanding Company stock on the open market. The stock purchased was used to offset the issuance of shares under the Company’s new ESOP. The Company purchased 48,000 shares, which were all granted to the ESOP.

In November 2004, the Company’s Board of Directors authorized the repurchase of up to $2.5 million of Company stock, to be completed no later than January 15, 2006. The amount of the stock repurchases was set based upon the anticipated number of shares that were required to fund the Company’s ESOP, and employee stock purchase plan, through fiscal year 2005. The Company purchased 8,700 shares at an average cost of $9.52 per share and 2,700 shares at an average cost of $9.80 per share for the periods ending December 25, 2004 and December 31, 2005, respectively. The stock purchases were made in the open market. Market purchases were made subject to restrictions relating to volume, price and timing in an effort to minimize the impact of the purchases on the market for the Company’s securities. All shares were retired during the year of purchase.

The deferred income is a result of the supply agreement with Mannesmann Rexroth, A.G., a German full-line hydraulic component and systems manufacturer, entered into during 1999. This agreement expires in 2010. Deferred compensation relates to Director compensation for attendance at Board meetings. Amounts will be paid upon an individual ceasing to be a Director of the Company.
Critical Accounting Policies and Estimates
The Company currently only applies judgment and estimates which may have a material effect on the eventual outcome of assets, liabilities, revenues and expenses for impairment of long-lived assets, accounts receivable, inventory, goodwill and accruals. The following explains the basis and the procedure for each account where judgment and estimates are applied.
Revenue Recognition
The Company reports revenues, net of sales incentives, when title passes and risk of loss transfers to the customer. The effect of material non-recurring events is provided for when they become known.
Impairment of Long-Lived Assets
In accordance with Statement of Financial Accounting Standards (“FAS”) No. 144, Accounting for Impairment or Disposal of Long-lived Assets (“FAS 144”), long-lived assets, such as property and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of the asset is measured by comparison of its carrying amount to future net cash flows the asset is expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset exceeds its fair value.
The Company assesses the recoverability of goodwill and intangible assets not subject to amortization under FAS No. 142, Goodwill and Other Intangible Assets (“FAS 142”). See Goodwill below.
Accounts Receivable
The Company sells to most of its customers on a recurring basis, primarily through distributors with which the Company maintains long-term relationships. As a result, bad debt experience has not been material. The allowance for doubtful accounts is determined on a specific identification basis by a review of those accounts that are significantly in arrears. There can be no assurance that a distributor or a large direct sale customer with overdue accounts receivable balances will not develop financial difficulties and default on payment. See Consolidated Balance Sheets for allowance amounts.

Table of Contents

Inventory
The Company offers a wide variety of standard products and as a matter of policy does not discontinue products. On an ongoing basis, component parts found to be obsolete through design or process changes are disposed of and charged to material cost. The Company reviews on-hand balances of products and component parts against specific criteria. Products and component parts without usage or that have excess quantities on hand are evaluated. An inventory reserve is then established for the full inventory carrying value of those products and component parts deemed to be obsolete or slow moving. See Note 6 to the Financial Statements for inventory reserve amounts.
Goodwill
The Company acquired its Korean operations in September 1998 using the purchase method. As a result, goodwill is reflected on the Consolidated Balance Sheet. A valuation based on the cash flow method was performed at December 31, 2005 and December 25, 2004. It was determined that the value of the goodwill was not impaired. There is no assurance that the value of the acquired company will not decrease in the future due to changing business conditions. See Note 8 to the Financial Statements for goodwill amounts.
Accruals
The Company makes estimates related to certain employee benefits and miscellaneous accruals. Estimates for employee benefit accruals are based on information received from plan administrators in conjunction with management’s assessments of estimated liabilities related to workers’ compensation, health care benefits and annual contributions to an employee stock ownership plan (“ESOP”), established in 2004 as part of the Company’s retirement plan. Estimates for miscellaneous accruals are based on management’s assessment of estimated liabilities for costs incurred.
As of July 1, 2003, the Company accrues for health care benefit costs under a self-funded plan utilizing estimates provided by a third party administrator and insurance company. The Company purchases re-insurance for both specific and aggregate stop losses on claims that exceed $75,000 on an individual basis and approximately $3.8 million on an aggregate basis.
New Accounting Pronouncements
In November 2004, the FASB issued FAS No. 151 (“FAS 151”), Inventory Costs, an amendment of ARB No. 43, Chapter 4. The amendments made by FAS 151 clarify that abnormal amounts of idle facility expense, freight, handling costs and wasted materials (spoilage) should be recognized as current-period charges and requires the allocation of fixed production overheads to inventory based on the normal capacity of the production facilities. While FAS 151 enhances Accounting Research Bulletin No. 43, Restatement and Revision of Accounting Research Bulletins, and clarifies the accounting for abnormal amounts of idle facility expense, freight, handling costs and wasted material (spoilage), the statement also removes inconsistencies between ARB 43 and International Accounting Standards No. 2 (“IAS 2”) and amends ARB 43 to clarify that abnormal amounts of costs should be recognized as period costs. Under some circumstances, according to ARB 43, the above listed costs may be so abnormal as to require treatment as current period charges. FAS 151 requires these items be recognized as current-period charges regardless of whether they meet the criterion of “so abnormal” and requires allocation of fixed production overheads to the costs of conversion.
This standard will be effective for inventory costs incurred during fiscal years beginning after June 15, 2005. The impact of the adoption of FAS 151 on the Company’s reported operating results, financial position and existing financial statement disclosure is not expected to be material.
In December, 2004, the FASB issued FAS No. 123 (revised 2004) (“FAS 123(R)”), Share-Based Payment, which is a revision of FAS 123. FAS 123(R) supersedes APB 25 and FAS 123, and amends FAS No. 95, Statement of Cash Flows. This Statement requires entities to recognize the cost of employee services received in exchange for awards of equity instruments based on the grant-date fair value of those awards (with limited exceptions). This Statement eliminates the alternative to use APB 25’s intrinsic value method of accounting that was provided in FAS 123 as originally issued. Under APB 25, issuing stock options to employees at or above fair value generally resulted in no recognition of compensation cost.

23


Table of Contents

FAS 123(R) also requires that the Company estimate the number of awards that are expected to vest and to revise the estimate as the actual forfeitures differ from the estimate. This standard is effective as of the beginning of the first annual reporting period that begins after June 15, 2005.
FAS 123(R) requires that the benefits of tax deductions in excess of recognized compensation cost be reported as a financing cash flow, rather than as an operating cash flow, thus reducing net operating cash flows and increasing net financing cash flows in the periods after the effective date. The Company cannot estimate what these amounts will be in the future because they depend on, among other things, when employees exercise stock options.
The Company currently follows the disclosure only provisions of FAS 148, and has elected to follow APB 25 and related interpretations in accounting for its employee stock options. The Company uses the Black-Scholes formula to estimate the value of stock options granted to employees for disclosure purposes. FAS 123(R) requires that the Company use the valuation technique that best fits the circumstances
The Company currently expects to use the modified-prospective method whereby compensation cost for the portion of awards for which the requisite service has not yet been rendered that are outstanding as of the adoption date will be recognized over the remaining service period. The compensation cost for that portion of awards will be based on the grant-date fair value of those awards as calculated for pro forma disclosures using the Black-Scholes valuation model. All new awards and awards that are modified, repurchased, or cancelled after the adoption date will be accounted for under the provisions of FAS 123(R). The amounts reflected in Note 2 to the Financial Statements, are anticipated to approximate the effect of the adoption of this Statement. Additionally, the Company will recognize compensation expense related to the Employee Stock Purchase Plan, which has not previously been recorded.
Off Balance Sheet Arrangements
The Company does not engage in any off balance sheet financing arrangements. In particular, the Company does not have any interest in variable interest entities, which include special purpose entities and structured finance entities.
The Company uses the equity method of accounting to account for its investments in Sun China and WhiteOak. The Company does not have a majority ownership in or exercise control over either of the entities. The Company does not believe that its investments in Sun China or WhiteOak qualify as Variable Interest Entities, within the scope of FASB Interpretation (FIN) No. 46, Consolidation of Variable Interest Entities, an interpretation of ARB No. 5, nor are they material to the financial statements of the Company at December 31, 2005.
Seasonality
The Company generally has experienced increased sales during the second quarter of the year largely as a result of the order patterns of our customers. As a result, the Company’s second quarter net sales, income from operations, and net income historically are the highest of any quarter during the year.
Inflation
The impact of inflation on the Company’s operating results has been moderate in recent years, reflecting generally lower rates of inflation in the economy. While inflation has not had, and the Company does not expect that it will have, a material impact upon operating results, there is no assurance that the Company’s business will not be affected by inflation in the future.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
The Company is exposed to market risk from changes in interest rates on borrowed funds, which could affect its results of operations and financial condition. The Company had approximately $1.1 million in variable-rate debt outstanding at December 31, 2005. The Company has managed this risk by its ability to select the interest rate on its debt financing at LIBOR plus 1.5% or the Bank’s Base Rate, whichever is more advantageous. Beginning in August 2006, the interest rate on its debt financing will remain variable based upon the Company’s leverage ratio. At December 31, 2005, a 1% change in interest rates up or down would have affected the Company’s income statement on an annual basis by approximately $11,000 at the current, variable-rate outstanding debt level. At December 25, 2004, the Company had $10.3 million in variable-rate debt outstanding.
The Company’s exposure to foreign currency exchange fluctuations relates primarily to the direct investment in its facilities in the United Kingdom, Germany, and Korea. The Company does not use financial instruments to hedge foreign currency exchange rate changes.

To the Board of Directors and
Shareholders of Sun Hydraulics Corporation:
We have audited the accompanying consolidated balance sheets of Sun Hydraulics Corporation (a Florida corporation) and subsidiaries as of December 31, 2005 and December 25, 2004, and the related consolidated statements of operations, shareholders’ equity and comprehensive income, and cash flows for each of the two years in the period ended December 31, 2005. 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 the standards of the Public Company Accounting Oversight Board (United States). 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, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Sun Hydraulics Corporation and subsidiaries as of December 31, 2005 and December 25, 2004, and the results of their operations and their cash flows for each of the two years in the period ended December 31, 2005 in conformity with accounting principles generally accepted in the United States of America.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Sun Hydraulics Corporation’s internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and our report dated March 6, 2006 expressed an unqualified opinion on management’s assessment and the effectiveness of internal control over financial reporting.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
A summary of the significant accounting policies followed in the preparation of the Company’s consolidated financial statements is set forth below:
Principles of Consolidation
The consolidated financial statements include the accounts and operations of Sun Hydraulics and its direct and indirect subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation. The Company uses the equity method of accounting to account for its investments in Sun China and WhiteOak. The Company does not have a majority ownership in or exercise control over either of the entities.
Critical Accounting Policies and Estimates
The Company currently only applies judgment and estimates, which may have a material effect on the eventual outcome of assets, liabilities, revenues and expenses, for impairment of long-lived assets, accounts receivable, inventory, goodwill and accruals. The following explains the basis and the procedure for each account where judgment and estimates are applied.
Revenue Recognition
The Company reports revenues, net of sales incentives, when title passes and risk of loss transfers to the customer. The effect of material non-recurring events is provided for when they become known.
Impairment of Long-Lived Assets
In accordance with Statement of Financial Accounting Standards (“FAS”) No. 144, Accounting for Impairment or Disposal of Long-lived Assets (“FAS 144”), long-lived assets, such as property and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of the asset is measured by comparison of its carrying amount to future net cash flows the asset is expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset exceeds its fair market value.
The Company assesses the recoverability of goodwill and intangible assets not subject to amortization under FAS No. 142, Goodwill and Other Intangible Assets (“FAS 142”). See Goodwill below.

Accounts Receivable
The Company sells to most of its customers on a recurring basis, primarily through distributors with which the Company maintains long-term relationships. As a result, bad debt experience has not been material. The allowance for doubtful accounts is determined on a specific identification basis by a review of those accounts that are significantly in arrears. There can be no assurance that a distributor or a large direct sale customer with overdue accounts receivable balances will not develop financial difficulties and default on payment. See the Consolidated Balance Sheets for allowance amounts.
Inventory
The Company offers a wide variety of standard products and as a matter of policy does not discontinue products. On an ongoing basis, component parts found to be obsolete through design or process changes are disposed of and charged to material cost. The Company reviews on-hand balances of products and component parts against specific criteria. Products and component parts without usage or that have excess quantities on hand are evaluated. An inventory reserve is then established for the full inventory carrying value of those products and component parts deemed to be obsolete or slow moving. See Note 6 to the Financial Statements for inventory reserve amounts.
Goodwill
The Company acquired its Korean operations in September 1998 using the purchase method. As a result, goodwill is reflected on the Consolidated Balance Sheet. A valuation based on the cash flow method was performed at December 31, 2005 and December 25, 2004. It was determined that the value of the goodwill was not impaired. There is no assurance that the value of the acquired company will not decrease in the future due to changing business conditions. See Note 8 to the Financial Statements for goodwill amounts.
Accruals
The Company makes estimates related to certain employee benefits and miscellaneous accruals. Estimates for employee benefit accruals are based on information received from plan administrators in conjunction with management’s assessments of estimated liabilities related to workers’ compensation, health care benefits and annual contributions to an employee stock ownership plan (“ESOP”), established in 2004 as part of the Company’s retirement plan. Estimates for miscellaneous accruals are based on management’s assessment of estimated liabilities for costs incurred.
As of July 1, 2003, the Company accrues for health care benefit costs under a self-funded plan utilizing estimates provided by a third party administrator and insurance company. The Company purchases re-insurance for both specific and aggregate stop losses on claims that exceed $75,000 on an individual basis and approximately $3.8 million on an aggregate basis.
Stock Split
On June 10, 2005, the Company declared a three-for-two stock split, effected in the form of a 50% stock dividend, to shareholders of record on June 30, 2005, payable on July 15, 2005. The Company issued approximately 3,600,000 shares of common stock as a result of the stock split. The effect of the stock split on outstanding shares, earnings per share and dividends per share has been retroactively applied to all periods presented.
Reclassification
Certain amounts shown in the 2004 and 2003 consolidated financial statements have been reclassified to conform to the 2005 presentation.
Management Estimates and Assumptions
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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.

Table of Contents

52-53 Week Fiscal Year
The Company reports on a fiscal year that ends on the Saturday closest to December 31st. Each quarter generally consists of two 4-week periods and one 5-week period. As a result of the 2005 fiscal year ending December 31, 2005, the quarter-ended April 2, 2005 consisted of one 4-week period and two 5-week periods, resulting in a 53-week year.
Cash and Cash Equivalents
The Company considers all short-term highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.
Inventories
Inventories are valued at the lower of cost or market, cost being determined on a first-in, first-out basis. Obsolete and slow moving inventory is evaluated and reserves are established based on specific criteria determined by management.
Property, Plant and Equipment
Property, plant and equipment is stated at cost. Expenditures for repairs and improvements that significantly add to the productive capacity or extend the useful life of an asset are capitalized. Repairs and maintenance are expensed as incurred. Depreciation is computed using the straight line method over the following useful lives:
         
    Years
Computer equipment
    3 - 5  
Machinery and equipment
    4 - 12  
Furniture and fixtures
    4 - 10  
Leasehold and land improvements
    5 - 15  
Buildings
    40  
Gains or losses on the retirement, sale, or disposition of plant, property, and equipment are reflected in the Consolidated Statement of Operations in the period in which the assets are taken out of service.
Valuation Assessment of Long-Lived Assets
Management periodically evaluates long-lived assets for potential impairment and will provide for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be fully recoverable. Assets are reviewed for utilization on a monthly basis by management in conjunction with employees who work directly with the assets.
Goodwill
Goodwill, which represents the excess of the purchase price of acquisition over the fair value of the net assets acquired and other acquisition costs, is carried at cost. Effective January 1, 2002, the Company adopted FAS 142. Under FAS 142, goodwill is no longer subject to amortization. Instead, FAS 142 requires goodwill to be reviewed for impairment on an annual basis, or more frequently if events or circumstances indicate possible impairment.
Other Assets
Other assets consist of equity investments in the Company’s joint ventures in China and WhiteOak. The equity investments were recorded at cost and have been adjusted for investment income or loss and dividend distributions for each quarterly period since their origin.
Revenue Recognition
Sales are recognized when products are shipped and title to the products is passed to the customer. Sales incentives are granted to customers based upon the volume of purchases. These sales incentives are recorded at the time of sales as a reduction of gross sales.

Shipping and Handling Costs
Shipping and handling costs billed to distributors and customers are recorded in revenue. Shipping costs incurred by the Company are recorded in cost of goods sold.
Foreign Currency Translation and Transactions
The Company follows the translation policy provided by FAS No. 52, Foreign Currency Translation. The Pound Sterling is the functional currency of Sun Ltd. The Euro is the functional currency of Sun GmbH. The South Korean Won is the functional currency of Sun Korea. The U.S. Dollar is the functional currency for Sun Hydraulics and the reporting currency for the consolidated group. The assets and liabilities of Sun Ltd., Sun GmbH, and Sun Korea are translated at the exchange rate in effect at the balance sheet date, and income and expense items are translated at the average annual rate of exchange for the period. The resulting unrealized translation gains and losses are included as a component of shareholders’ equity designated as “accumulated other comprehensive income.” Realized gains and losses from foreign currency transactions are included in miscellaneous (income) expense.
Income Taxes
The Company follows the income tax policy provided by FAS No. 109, Accounting for Income Taxes (“FAS 109”). This Statement provides for a liability approach under which deferred income taxes are provided for based upon enacted tax laws and rates applicable to the periods in which the taxes become payable. These differences result from items reported differently for financial reporting and income tax purposes, primarily depreciation, accrued expenses and reserves.
Stock-Based Compensation
The Company has adopted the disclosure only provisions of FAS No. 148, Accounting for Stock-Based Compensation – Transition and Disclosure, an amendment to FAS No. 123, Accounting for Stock-Based Compensation (“FAS 148”), and has elected to follow Accounting Principles Board Opinion (APB) No. 25, Accounting for Stock Issued to Employees and related interpretations in accounting for its employee stock options. Under APB 25, because the exercise price of employee stock options equals the market price of the underlying stock on the date of grant, no compensation expense is recorded.
If the company had elected to recognize compensation expense for stock options based on the fair value at grant date, consistent with the method prescribed by FAS No. 123, Accounting for Stock-Based Compensation (“FAS 123”), net income and earnings per share would have been reduced to the pro forma amounts below. The pro forma amounts were determined using the Black-Scholes valuation model with weighted average assumptions as set forth below.

These pro forma amounts may not be representative of future disclosures since the estimated fair value of stock options is amortized to expense over the vesting period and additional options may be granted in future years. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model.
3.   ACQUISITIONS
On June 28, 2005, Sun Hydraulics acquired shares of common stock representing 40% of the outstanding shares of WhiteOak. WhiteOak designs and produces electronic amplifiers and other control products. The Company, together with WhiteOak, will co-develop products to be used in and in conjunction with other Company products. The acquisition price paid by the Company was $400. The excess paid over pro rata share of net assets of $270 is being classified as developed technology and is being amortized over a period of 10 years.
4.   FAIR VALUE OF INVESTMENTS
The fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced sale or liquidation. The following methods and assumptions were used to estimate the fair value of each class of financial instruments.
The carrying amounts of cash and cash equivalents, restricted cash, accounts receivable, other current assets, accounts payable, accrued expenses and other liabilities approximate fair value based on their short-term status.
The carrying amount of long-term debt approximates fair value, as the interest rates on the debt approximate rates currently available to the Company for debt with similar terms and remaining maturities.
5.   RESTRICTED CASH
On December 31, 2005 and December 25, 2004, the Company had restricted cash of $413 and $462, respectively. The restricted cash balance consisted of reserves for customs and excise taxes in the U.K. operation. The

8.   GOODWILL
On December 31, 2005 and December 25, 2004, the Company had $715 of goodwill related to its acquisition of Sun Korea.
Valuation models reflecting the expected future cash flow projections were used to value Sun Korea at December 31, 2005 and December 25, 2004. The analysis indicated that there was no impairment of the carrying value of the goodwill.

Thereafter, the interest rate will vary based upon the Company’s leverage ratio. The Line of Credit is payable in full on August 1, 2011, but maturity may be accelerated by the Bank upon an Event of Default (as defined). Prepayment may be made without penalty or premium at any time upon the required notice to the Bank. At December 31, 2005, the Line of Credit had an outstanding balance of $999.
The Line of Credit is subject to debt covenants including: 1) Debt (as defined) to Tangible Net Worth (as defined) ratio of not more than 1.5:1.0, 2) Funded Debt (as defined) to EBITDA (as defined) ratio of not more than 2.5:1.0, and 3) EBIT (as defined) to Interest Expense (as defined) ratio of not less than 1.1:1.0; and requires the Company to maintain its primary domestic deposit accounts with the Bank. As of December 31, 2005, the Company was in compliance with all debt covenants.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts assets and liabilities for financial reporting purposes and the amounts used for income taxes. The temporary differences that give rise to significant portions of the deferred tax assets and liabilites as of December 31, 2005 and December 25, 2004 are presented below:
                 
    December 31,   December 25,

Net deferred tax liability
  $ (3,906 )   $ (4,594 )
     
A valuation allowance to reduce the deferred tax assets reported is required if, based on the weight of the evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. For the fiscal years ended 2005 and 2004, management has determined that a valuation allowance is not required. The foreign tax credit carryforward will expire through the year 2009.
The Company intends to indefinitely reinvest the earnings of its non-U.S. subsidiaries, which reflect full provision for non-U.S. income taxes, to expand its international operations. These earnings relate to ongoing operations and, at December 31, 2005, cumulative earnings were approximately $16 million. Accordingly, no provision has been made for U.S. income taxes that might be payable upon repatriation of such earnings. In the event any earnings of non-U.S. subsidiaries are repatriated, the Company will provide U.S. income taxes upon repatriation of such earnings, which will be offset by applicable foreign tax credits, subject to certain limitations.
14. STOCK OPTION PLANS
During 1996, the Company adopted the 1996 Stock Option Plan (the “Stock Option Plan”), which provides for the grant of incentive stock options and nonqualified stock options for the purchase of up to an aggregate of 1,500,000 shares of the Company’s common stock by officers, employees and directors of the Company. Under the terms of the plan, incentive stock options may be granted to employees at an exercise price per share of not less than the fair value per common share on the date of the grant (not less than 110% of the fair value in the case of holders of more than 10% of the Company’s voting stock). Nonqualified stock options may be granted at the discretion of the Company’s Board of Directors. The maximum term of an option may not exceed 10 years, and options become exercisable at such times and in such installments as determined by the Board of Directors.

The weighted average estimated fair value of stock options granted during 2005, 2004 and 2003 was $6.67, $3.72, and $1.47 per share, respectively.
During 2001, the Company adopted the 2001 Restricted Stock Plan, which provides for the grant of restricted stock of up to an aggregate of 412,500 shares of the Company’s common stock to officers, employees, consultants and directors of the Company. Under the terms of the plan, the minimum period before any shares become non-forfeitable may not be less than six months. The market value of the restricted stock at the date of grant was recorded as unearned compensation, a component of shareholders’ equity, and is being charged to expense over the respective vesting periods. Restricted stock expense for the years ended December 31, 2005, December 25, 2004, and December 27, 2003 totaled $342, $250, and $181, respectively.

On October 15, 2004, the Board of Directors granted 35,634 shares of restricted stock to employees. The restricted stock will be earned over a three year period. The restricted stock is expensed over the vesting period at a price of $8.23, the stock price on October 15, 2004.
On December 9, 2005, the Board of Directors granted 25,824 shares of restricted stock to employees. The restricted stock will be earned over a three year period. The restricted stock is expensed over the vesting period at a price of $18.41, the stock price on December 9, 2005. The grant increased restricted shares outstanding from 230,484 at December 25, 2004 to 256,672 at December 31, 2005. At December 31, 2005 and December 25, 2004, 161,995 and 101,061 of these shares, respectively, were vested.
During 2001, the Company adopted the Employee Stock Purchase Plan (“ESPP”), which became effective August 1, 2001. Most employees are eligible to participate. Employees who choose to participate are granted an opportunity to purchase common stock at 85 percent of market value on the first or last day of the quarterly purchase period, whichever is lower. The ESPP authorizes the issuance, and the purchase by employees, of up to 487,500 shares of common stock through payroll deductions. No employee is allowed to buy more than $25,000 of common stock in any year, based on the market value of the common stock at the beginning of the purchase period. Employees purchased approximately 12,017 shares at an average price of $14.72 and 20,013 shares at an average price of $5.75, under the ESPP during 2005 and 2004, respectively. At December 31, 2005 and December 25, 2004, 411,931 and 423,948 shares, respectively, remained available to be issued through the ESPP.
During 2004, the Board of Directors adopted and the shareholders approved the Nonemployee Director Equity and Deferred Compensation Plan (the “Plan”). Directors who are not officers of the Company are paid $4,000 for attendance at each meeting of the Board of Directors, as well as each meeting of each Board Committee on which they serve when the committee meeting is not held within one day of a meeting of the Board of Directors. Directors receive $1,500 of the $4,000 Director fee in shares of Company stock under the Plan. Directors also may elect under the Plan to receive all or part of the remainder of their fees in Company stock and to defer receipt of their fees until a subsequent year. The Plan authorizes the issuance of up to 120,000 shares of common stock. Directors were granted 3,561 and 4,112 shares during 2005 and 2004, respectively. At December 31, 2005 and December 25, 2004, 112,328 and 115,889 shares, respectively, remained available to be issued through the Plan.
15. STOCK REPURCHASE PLANS
In December 2005, the Company’s Board of Directors authorized the repurchase of up to $2.0 million of Company stock, to be completed no later than January 15, 2007. The stock purchases will be made in the open market or through privately negotiated transactions. Market purchases will be made subject to restrictions relating to volume, price and timing in an effort to minimize the impact of the purchases on the market for the Company’s securities. The amount of the stock repurchases was set based upon the anticipated number of shares that will be required to fund the Company’s ESOP, and employee stock purchase plan, through fiscal year 2006. As of December 31, 2005, the Company had repurchased 82,500 shares on the open market at an average cost of $18.87 per share. Of the 82,500 shares purchased, 65,000 were retired prior to December 31, 2005.
Subsequent to December 31, 2005, the Company repurchased 12,700 shares on the open market at an average cost of $19.16 per share. Total purchases under the plan have amounted to $1.8 million.
In November 2004, the Company’s Board of Directors authorized the repurchase of up to $2.5 million of Company stock, to be completed no later than January 15, 2006. The amount of the stock repurchases was set based upon the anticipated number of shares that were required to fund the Company’s ESOP, and employee stock purchase plan, through fiscal year 2005. The Company purchased 8,700 shares at an average cost of $9.52 per share and 2,700 shares at an average cost of $9.80 per share for the periods ending December 25, 2004 and December 31, 2005, respectively. The stock purchases were made in the open market. Market purchases were made subject to restrictions relating to volume, price and timing in an effort to minimize the impact of the purchases on the market for the Company’s securities. All shares were retired during the year of purchase.

17. EMPLOYEE BENEFITS
The Company has a defined contribution retirement plan covering substantially all of its eligible United States employees. Employer contributions under the retirement plan amounted to approximately $2,205, $2,346, and $686 during 2005, 2004, and 2003, respectively.
The Company provides supplemental pension benefits to its employees of foreign operations in addition to mandatory benefits included in local country payroll tax statutes. These supplemental pension benefits amounted to approximately $437, $437, and $266 during 2005, 2004, and 2003, respectively.
In June 2004, the Company’s Board of Directors approved the establishment of an Employee Stock Ownership Plan (“ESOP”) as the discretionary match portion of its 401(k) retirement plan. Prior to 2004, discretionary matches to the 401(k) plan were made in cash. The Company contributes to the ESOP for all eligible United States employees. Under the ESOP, which is 100% company funded, the Company allocates common stock to each participants account. The allocation is generally a percentage of a participant’s compensation as determined by the Board of Directors on an annual basis. The ESOP is accounted for under Statement of Position 93-6 Employer’s Accounting for Employee Stock Ownership Plans.
In September 2004, the Company made an initial one-time contribution of 48,000 shares of its common stock to the ESOP. The Company made annual contributions to the ESOP of 57,746 shares and 109,935 shares in January 2006 and January 2005, related to fiscal year 2005 and 2004, respectively. Contributions were based on 2005 and 2004 compensation. All shares receive regular quarterly dividends payable to the ESOP to cover plan expenses.
The Company incurred compensation expense under the ESOP of approximately $1,180 and $1,572 during 2005 and 2004, respectively. There was no discretionary match to the 401(k) in 2003.
Shares contributed to the ESOP are restricted for one year. Participants may then sell their shares to enable diversification within their individual 401(k) accounts. The Company does not have any repurchase obligations under the ESOP.
During 2005, the Company awarded deferred cash bonuses to key employees of its foreign operations. The deferred cash bonuses are similar to stock appreciation rights, in that such bonuses are tied to the value of the

Company’s common stock. Awards are recognized over the deferral period as variable plan awards. The Company recognized approximately $181 of compensation expense in 2005 related to the awards.
18. SEGMENT REPORTING
The individual subsidiaries comprising the Company operate predominantly in a single industry as manufacturers and distributors of hydraulic components. The Company is multinational with operations in the United States, and subsidiaries in the United Kingdom, Germany, Korea, and France. Amounts for France, due to their immateriality, are included with the U.S. In computing operating profit for the foreign subsidiaries, no allocations of general corporate expenses have been made. Management bases its financial decisions by the geographical location of its operations.
Identifiable assets of the foreign subsidiaries are those assets related to the operation of those companies. United States assets consist of all other operating assets of the Company. Segment information is as follows:

19.   COMMITMENTS AND CONTINGENCIES
The Company is not a party to any legal proceedings other than routine litigation incidental to its business. In the opinion of management, the amount of ultimate liability with respect to these actions will not materially affect the results of operations, financial position or cash flows of the Company.
OPERATING LEASES — The Company leases a manufacturing facility in Lenexa, Kansas and production support facilities in Sarasota, Florida under operating leases having initial terms expiring between 2006 and 2008. The lease for the manufacturing facility in Kansas has a term of 5 years, expiring on November 14, 2008, and represents approximately 17,000 square feet of space. The lease for the production support facilities in Florida are

INSURANCE — On July 1, 2003, the Company changed its group health insurance plan that covers U.S. employees and their families from a fully-insured policy to a self-funded plan. The Company purchases re-insurance for both specific and aggregate stop losses on claims that exceed $75,000 on an individual basis and approximately $3.8 million on an aggregate basis. The Company records a liability for all unresolved claims at the anticipated cost to the Company at the end of the period based on the estimates provided by a third party administrator and insurance company, plus an estimate for amounts incurred but not recorded. The Company believes it has adequate reserves for all self-insurance claims.
20. NEW ACCOUNTING PRONOUNCEMENTS
In November 2004, the FASB issued FAS No. 151 (“FAS 151”), Inventory Costs, an amendment of ARB No. 43, Chapter 4. The amendments made by FAS 151 clarify that abnormal amounts of idle facility expense, freight, handling costs and wasted materials (spoilage) should be recognized as current-period charges and requires the allocation of fixed production overheads to inventory based on the normal capacity of the production facilities. While FAS 151 enhances Accounting Research Bulletin No. 43, Restatement and Revision of Accounting Research Bulletins, and clarifies the accounting for abnormal amounts of idle facility expense, freight, handling costs and wasted material (spoilage), the statement also removes inconsistencies between ARB 43 and International Accounting Standards No. 2 (“IAS 2”) and amends ARB 43 to clarify that abnormal amounts of costs should be recognized as period costs. Under some circumstances, according to ARB 43, the above listed costs may be so abnormal as to require treatment as current period charges. FAS 151 requires these items be recognized as current-period charges regardless of whether they meet the criterion of “so abnormal” and requires allocation of fixed production overheads to the costs of conversion.
This standard will be effective for inventory costs incurred during fiscal years beginning after June 15, 2005. The impact of the adoption of FAS 151 on the Company’s reported operating results, financial position and existing financial statement disclosure is not expected to be material.
In December, 2004, the FASB issued FAS No. 123 (revised 2004) (“FAS 123(R)”), Share-Based Payment, which is a revision of FAS 123. FAS 123(R) supersedes APB 25 and FAS 123, and amends FAS No. 95, Statement of Cash Flows. This Statement requires entities to recognize the cost of employee services received in exchange for awards of equity instruments based on the grant-date fair value of those awards (with limited exceptions). This Statement eliminates the alternative to use APB 25’s intrinsic value method of accounting that was provided in FAS 123 as originally issued. Under APB 25, issuing stock options to employees at or above fair value generally resulted in no recognition of compensation cost.
FAS 123(R) also requires that the Company estimate the number of awards that are expected to vest and to revise the estimate as the actual forfeitures differ from the estimate. This standard is effective as of the beginning of the first annual reporting period that begins after June 15, 2005.
FAS 123(R) requires that the benefits of tax deductions in excess of recognized compensation cost be reported as a financing cash flow, rather than as an operating cash flow, thus reducing net operating cash flows and increasing net financing cash flows in the periods after the effective date. The Company cannot estimate what these amounts will be in the future because they depend on, among other things, when employees exercise stock options.
The Company currently follows the disclosure only provisions of FAS 148, and has elected to follow APB 25 and related interpretations in accounting for its employee stock options. The Company uses the Black-Scholes formula

48


Table of Contents

to estimate the value of stock options granted to employees for disclosure purposes. FAS 123(R) requires that the Company use the valuation technique that best fits the circumstances.
The Company currently expects to use the modified-prospective method whereby compensation cost for the portion of awards for which the requisite service has not yet been rendered that are outstanding as of the adoption date will be recognized over the remaining service period. The compensation cost for that portion of awards will be based on the grant-date fair value of those awards as calculated for pro forma disclosures using the Black-Scholes valuation model. All new awards and awards that are modified, repurchased, or cancelled after the adoption date will be accounted for under the provisions of FAS 123(R). The amounts reflected in Note 2 to the Financial Statements, are anticipated to approximate the effect of the adoption of this Statement. Additionally, the Company will recognize compensation expense related to the Employee Stock Purchase Plan, which has not previously been recorded.

Our disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in reports that we file or submit pursuant to the Securities Exchange Act of 1934, as amended, are accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
Internal Control Over Financial Reporting
Management is responsible for establishing and maintaining adequate internal control over financial reporting.
There were no changes in the Company’s internal control over financial reporting during the quarter ended December 31, 2005, that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
Management’s Report on Internal Control over Financial Reporting
Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that:
  pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;
 
  provide reasonable assurance that transactions are recorded, as necessary, to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and
 
  provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Management conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting based on the criteria set forth in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation under the Internal Control — Integrated Framework, management concluded that the internal control over financial reporting was effective as of December 31, 2005.

Management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2005 has been audited by Grant Thornton LLP, an independent registered public accounting firm, as stated in their report which is included herein.
Report of Independent Registered Public Accounting Firm
To the Board of Directors and
Shareholders of Sun Hydraulics Corporation:
We have audited management’s assessment, included in the accompanying Management Report on Internal Control Over Financial Reporting, that Sun Hydraulics Corporation (a Florida Corporation) maintained effective internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Sun Hydraulics Corporation’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the company’s internal control over financial reporting based on our audit.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Equity compensation plans approved by shareholders include the 1996 Stock Option Plan, the 2001 Restricted Stock Plan, the Employee Stock Purchase Plan, and the 2004 Nonemployee Director Equity and Deferred Compensation Plan. All shares to be issued upon exercise in column (a) and the weighted average exercise price in column (b) represent shares issued under the 1996 Stock Option Plan. The number of securities available for future issuance in column (c) were: 382,593 shares under the 1996 Stock Option Plan, 411,931 shares under the Employee Stock Purchase Plan, 156,192 shares under the 2001 Restricted Stock Plan, and 112,327 shares under the 2004 Nonemployee Director Equity and Deferred Compensation Plan.
The only equity compensation plan not approved by shareholders was the 1999 Stock Award Plan. 4,500 shares were authorized for grant under the 1999 Stock Award Plan, which was approved by the Board of Directors on May 21, 1999. The general purpose of the Plan is to recognize and acknowledge extraordinary contributions of employees through the grant of shares of common stock, thereby providing them with a more direct stake in the future welfare of the Company and encouraging them to continue to demonstrate leadership and commitment to the Company. Subject to supervision by the Board and the provisions of the Plan, the Company’s president has the authority to determine the employees to whom awards shall be granted and the number of shares of common stock to be the subject of each award. As of December 31, 2005, there were 450 shares remaining for future grants, and there were no outstanding options, warrants, or rights associated with this plan.
In December 2005, the Company’s Board of Directors authorized the repurchase of up to $2.0 million of Company stock, to be completed no later than January 15, 2007. The stock purchases will be made in the open market or through privately negotiated transactions. Market purchases will be made subject to restrictions relating to volume, price and timing in an effort to minimize the impact of the purchases on the market for the Company’s securities. The amount of the stock repurchases was set based upon the anticipated number of shares that will be required to fund the Company’s ESOP, and employee stock purchase plan, through fiscal year 2006. As of December 31, 2005, the Company had repurchased 82,500 shares on the open market at an average cost of $18.87 per share. Of the 82,500 shares purchased, 65,000 were retired prior to December 31, 2005.
Subsequent to December 31, 2005, the Company repurchased 12,700 shares on the open market at an average cost of $19.16 per share. Total purchases under the plan have amounted to $1.8 million.

In November 2004, the Company’s Board of Directors authorized the repurchase of up to $2.5 million of Company stock, to be completed no later than January 15, 2006. The amount of the stock repurchases was set based upon the anticipated number of shares that were required to fund the Company’s ESOP, and employee stock purchase plan, through fiscal year 2005. The Company purchased 8,700 shares at an average cost of $9.52 per share and 2,700 shares at an average cost of $9.80 per share for the periods ending December 25, 2004 and December 31, 2005, respectively. The stock purchases were made in the open market. Market purchases were made subject to restrictions relating to volume, price and timing in an effort to minimize the impact of the purchases on the market for the Company’s securities. All shares were retired during the year purchased.
