                                  PART I

ITEM 1. BUSINESS.

Background

Simpson Manufacturing Co., Inc. (the "Company"), through its subsidiary, 
Simpson Strong-Tie Company Inc. ("Simpson Strong-Tie" or "SST"), designs, 
engineers and is a leading manufacturer of wood-to-wood, wood-to-concrete 
and wood-to-masonry connectors, and through its subsidiary, Simpson Dura-
Vent Company, Inc. ("Simpson Dura-Vent" or "SDV"), designs, engineers and 
manufactures venting systems for gas and wood burning appliances. The 
Company markets its products to the residential construction, light 
industrial and commercial construction, remodeling and do-it-yourself 
("DIY") markets. The Company believes that SST benefits from strong brand 
name recognition among architects and engineers who frequently specify in 
building plans the use of SST products, and that SDV benefits from strong 
brand name recognition among contractors, dealers, distributors and 
original equipment manufacturers ("OEMs") to which SDV markets its 
products. The Company has continuously manufactured structural connectors 
since 1956. See Note 14 to the Company's consolidated financial statements 
for information regarding the net sales, income from operations, 
depreciation and amortization, capital expenditures and acquisitions and 
total assets of the Company's two primary segments.

Connectors produced by Simpson Strong-Tie typically are steel devices that 
are used to strengthen, support and connect joints in residential and 
commercial construction and DIY projects. These products enhance the safety 
and durability of the structures in which they are installed and can save 
time and labor costs for the contractor. SST's connector products increase 
structural integrity and improve structural resistance to seismic, wind and 
other forces. Applications range from building framing to deck construction 
to DIY projects. SST produces and markets over five thousand standard and 
custom products.

Simpson Dura-Vent's venting systems are used to vent gas furnaces and water 
heaters, gas fireplaces and stoves, wood burning stoves and pellet stoves. 
SDV's metal vents, chimneys and chimney liner systems exhaust the products 
of combustion to the exterior of the building, and some products introduce 
outside air into the appliance. SDV designs its products for ease of 
assembly and safe operation and to achieve a high level of performance. SDV 
produces and markets approximately two thousand different venting products 
and systems.

The Company emphasizes continuous new product development and often obtains 
patent protection for its new products. The Company's products are marketed 
in all 50 states of the United States and in England, France, Germany, 
Canada, Mexico, Chile, Japan and Australia. Both Simpson Strong-Tie and 
Simpson Dura-Vent products are distributed through a contractor and dealer 
distributor network, home centers and OEMs.

The Company has developed and uses automated manufacturing processes. Its 
innovative manufacturing systems and techniques have allowed it to control 
manufacturing costs, even while developing both new products and products 
that meet customized requirements and specifications. The Company's 
development of specialized manufacturing processes has also permitted 
increased operating flexibility and enhanced product design innovation. The 
Company has developed a quality management system that employs numerous 
quality-control procedures. Since 1996, SST's quality management system has 
been registered under ISO 9001. The Company has 11 manufacturing locations 
in the United States, Canada, France and the United Kingdom.

The Company is a California corporation and was reorganized in 1994 as a 
holding company for Simpson Strong-Tie and Simpson Dura-Vent.


Industry and Market Trends

Based on trade periodicals, participation in trade and professional 
associations and communications with governmental and quasi-governmental 
organizations and customers and suppliers, the Company believes that a 
variety of events and trends have resulted in significant developments in 
the markets that the Company serves. Some of these events and trends are 
discussed below.

Natural disasters throughout the world have focused attention on safety 
concerns relating to the structural integrity of homes and other buildings. 
The 1995 earthquake in Kobe, Japan, the 1994 earthquake in Northridge, 
California, the 1989 Loma Prieta earthquake in Northern California, 
Hurricanes Hugo in 1989 and Andrew in 1992 in the Southeast, and other less 
cataclysmic natural disasters damaged and destroyed innumerable homes and 
other buildings, resulting in heightened consciousness of the fragility of 
some of those structures.

In recent years, architects, engineers, model code agencies, contractors, 
building inspectors and legislators have continued efforts to improve 
structural integrity and safety of homes and other buildings in the face of 
disasters of various types, including seismic events, storms and fires. 
Based on ongoing participation in trade and professional associations and 
communications with governmental and quasi-governmental regulatory 
agencies, the Company believes that building codes are being strengthened 
and that their enforcement is becoming more rigorous. The Company's 
products are designed to respond to increasing demand resulting from these 
trends.

The requirements of the Endangered Species Act, the Federal Lands Policy 
Management Act and the National Forest Management Act have resulted in 
increasingly limited amounts of timber available for harvest from public 
lands. This has contributed to an increase in lumber prices and a 
concomitant increase in the use of engineered wood products. Engineered 
wood products, which substitute for strong, clear-grained lumber 
historically obtained from logging older, large-diameter trees, have been 
developed to conserve lumber. Engineered wood products frequently require 
specialized connectors. Sales of Simpson Strong-Tie's engineered wood 
connector products increased significantly in 1997 and 1998.

Concerns about energy conservation and air quality have led to increasing 
recognition of the advantages of natural gas as a heating fuel, including 
its abundance and clean burning characteristics. Use of natural gas for 
home heating has been increasing in the United States. According to the 
Census Bureau, the share of new single-family houses in 1997 heated with 
natural gas was 69%, a slight increase from 67% in 1995. Sales of gas 
fireplaces have increased in recent years relative to those of traditional 
wood burning fireplaces. Traditional wood burning fireplaces negatively 
affect both indoor and outdoor air quality. In contrast, direct vent gas 
fireplaces draw air for combustion from outdoors (through the double wall 
venting system) and feature sealed glass doors that reduce indoor air 
contamination. In the past, Simpson Dura-Vent products have not been sold 
into the traditional masonry and manufactured fireplace market. The recent 
trend from wood to gas fireplaces is viewed as a significant opportunity 
for SDV's gas venting products.

The Company has developed its distribution through home centers throughout 
the United States. The Company's sales to home centers increased 
significantly in 1998 and 1997. See "Item 7 - Management's Discussion and 
Analysis of Financial Condition and Results of Operations."

Business Strategy

The Company designs, manufactures and sells products that are of high 
quality and performance, easy to use and cost-effective for customers. The 
Company provides rapid delivery of its products and prompt engineering and 
sales support. Based on its communications with customers, engineers, 
architects, contractors and other industry participants, the Company 
believes that its products have strong brand name recognition, and the 
Company seeks to continue to develop the value of its brand names through a 
variety of customer-driven strategies. Information provided by customers 
has led to the development of many of the Company's products, and the 
Company expects that customer needs will continue to shape the Company's 
product development, marketing and services.


Specification in architects' and engineers' plans and drawings influences 
which products will be used for particular purposes and therefore is key to 
the use of the Company's products in construction projects. The Company 
encourages architects and engineers to specify the installation of the 
Company's products in projects they design and supervise, and encourages 
acceptance of the Company's products by construction contractors. The 
Company maintains frequent contacts with architects, engineers and 
contractors, as well as private organizations that provide information to 
building code officials, both to inform them regarding the quality, proper 
installation, capabilities and value of the Company's products and to 
update them about product modifications and new products that may be useful 
or needed. The Company sponsors seminars to inform architects, engineers 
and building officials on appropriate use and proper installation of the 
Company's products.

The Company seeks to expand its product and distribution coverage through 
several channels:

Distributors. The Company regularly evaluates its distribution coverage and 
service levels provided by its distributors and from time to time modifies 
its distribution strategy and implements changes to address weaknesses and 
opportunities. The Company has various programs to evaluate distributor 
product mix and conducts promotions to encourage distributors to add 
Company products that complement their mix of product offerings in their 
markets.

Through its efforts to increase specifications by architects and engineers, 
and through increasing the number of products sold to particular 
contractors, the Company seeks to increase sales to distributors that serve 
building contractors. The Company continuously seeks to expand the number 
of contractors served by each distributor through such sales efforts as 
demonstrations of product cost-effectiveness and information programs.

Home Centers. The Company intends to continue to increase penetration of 
the DIY markets by solicitation of home centers. The Company's Sales 
Representatives and Retail Specialists maintain on-going contact with home 
centers to provide timely product availability and product knowledge 
training. To satisfy specialized requirements of the home center market, 
the Company has developed extensive bar coding and merchandising aids and 
has concentrated a portion of its research efforts into the development of 
DIY products.

OEM Relationships. The Company works closely with manufacturers of 
engineered wood products and OEMs in developing and expanding the 
application and sales of Simpson Strong-Tie's engineered wood connector 
products and Simpson Dura-Vent's gas, wood and pellet stove venting 
products. SST has relationships with several of the largest manufacturers 
of engineered wood products, and SDV has OEM relationships with several 
major gas fireplace and gas stove manufacturers.

The Company is expanding its established facilities outside California to 
increase its presence and sales in markets east of the Rocky Mountains. 
During the last five years, the Company has expanded or has planned to 
expand nearly all of its manufacturing and warehouse facilities. Sales in 
the 37 states east of the Rocky Mountains represented approximately 48% of 
the Company's 1998 domestic sales. In the last five years, the Company 
commenced manufacturing in England, opened warehouse and distribution 
facilities in Western Canada and the Northeastern United States, purchased 
anchoring products manufacturers in Illinois and Eastern Canada and a 
connector product manufacturer in France, established a distribution 
operation in Chile, made an equity investment in a product design and 
distribution company in Germany and entered into distribution arrangements 
in Japan and Australia. The European investments are intended to establish 
a presence in the European Community through companies with existing 
customer bases and through servicing U.S.-based customers operating there. 
The Company intends to continue to pursue and expand operations outside the 
United States.

The Company's goal is to manufacture and warehouse its products in 
geographic proximity to its markets to provide availability and rapid 
delivery of products to customers and prompt response to customer requests 
for specially designed products and services. With respect to the DIY and 
dealer markets, the Company's strategy is to keep the customer's retail 
stores continuously stocked with adequate supplies of the full line of the 
Company's products that those stores carry. The Company manages its 
inventory to assure continuous product availability. Most customer orders 
are filled within a few days. High levels of manufacturing automation and 
flexibility allow the Company to maintain its quality standards while 
continuing to provide prompt delivery.

The Company's product research and development is based largely on needs 
that customers communicate to the Company. The Company typically has 
developed 10 to 15 new products annually (some of which may be produced in 
a range of sizes). The Company's strategy is to develop new products on a 
proprietary basis where possible. Of more than 80 patents that the Company 
owns, more than 70 cover products that the Company currently manufactures 
and markets. The Company has filed 55 patent applications that are pending.


The Company's long-term strategy is to develop, acquire or invest in 
product lines or businesses that (a) complement the Company's existing 
product lines, (b) can be marketed through its existing distribution 
channels, (c) might benefit from use of the Simpson Strong-Tie and Simpson 
Dura-Vent brand names, and (d) are responsive to needs of the Company's 
customers.

Simpson Strong-Tie

Overview

Connectors produced by Simpson Strong-Tie typically are steel devices that 
are used to strengthen, support and connect joints in residential and 
commercial construction and DIY projects. These products enhance the safety 
and durability of the structures in which they are installed and can save 
time and labor costs for the contractor. SST's connector products increase 
structural integrity and improve structural resistance to seismic, wind and 
other forces. Applications range from building framing to deck construction 
to DIY projects. SST produces and markets over five thousand standard and 
custom products.

In the United States, connector usage developed faster in the West than 
elsewhere due to the low cost and abundance of timber and to local 
construction practices. Increasingly, the market has been influenced both 
by a growing awareness that the devastation caused by seismic, wind and 
other disasters can be reduced through improved building codes and 
construction practices and by environmental concerns that contribute to the 
increasing cost and reduced availability of wood. Most Simpson Strong-Tie 
products are listed by recognized building standards agencies as complying 
with model building codes and are specified by architects and engineers for 
use in projects they are designing or supervising. The engineered wood 
products industry is developing in response to concerns about the 
availability of wood, and the Company believes that SST is the leading 
supplier of connectors for use with engineered wood products.

Products

Simpson Strong-Tie is a recognized brand name in the markets it serves. SST 
manufactures and markets three primary categories of connector products: 
wood-to-wood, wood-to-concrete and wood-to-masonry. SST also markets 
specialty screws and nails for proper installation of certain of its 
connector products. For tying wood members to the foundation, SST has 
designed and currently markets a line of anchor bolts and the associated 
parts for aligning the anchor bolts, as well as threaded rod, epoxy and 
mechanical anchors, which have seismic, retrofit and remodeling 
applications for both new construction and DIY markets.

Almost all of Simpson Strong-Tie's products are listed by recognized model 
building code agencies. To achieve such listings, SST conducts extensive 
product testing, which is witnessed and certified by independent testing 
engineers. The tests also provide the basis for publication of load ratings 
for SST structural connectors, and this information is used by architects, 
engineers, contractors and homeowners. The information is useful across the 
range of applications of SST's products, from the deck constructed by a 
homeowner to a multi-story structure designed by an architect or engineer 
in an earthquake zone.

Simpson Strong-Tie also manufactures connector products specifically 
designed for use with engineered wood products, such as wood I-joists. With 
increased timber costs and reduced availability of trees suitable for 
making traditional solid sawn lumber, construction with engineered wood 
products has increased substantially in the last three years. Over the same 
period, SST's net sales of engineered wood connectors through dealer and 
contractor distributors and engineered wood product manufacturers have also 
increased significantly.


New Product Development

Simpson Strong-Tie commits substantial resources to engineering and new 
product development. The majority of SST's products have been developed 
through SST's internal research and development program. Of the 67 U.S. and 
15 foreign patents that SST owns, more than 65 cover products that SST 
currently manufactures and markets. Over a quarter of SST's 1998 revenues 
were derived from products that are protected by patents. SST typically has 
developed 10 to 15 new products each year. SST's research and development 
expense for the three years ended December 31, 1998, 1997 and 1996, was 
$1,087,000, $957,000 and $1,025,000, respectively. As part of the new 
product development process, SST engineers, in cooperation with sales and 
marketing staff, meet regularly with architects, engineers, building 
inspectors, code officials and customers. Several new products derived from 
existing product lines are developed annually. SST recently developed and 
introduced a pre-fabricated shear-wall product for the new construction 
market and has expanded its line of chemical and mechanical anchoring 
products. The Company believes that existing distribution channels are 
receptive to product line extensions, thereby enhancing SST's ability to 
enter new markets.

Sales and Marketing

Simpson Strong-Tie's sales and marketing programs are implemented through 
SST's branch system. SST currently maintains branches in Northern and 
Southern California, Texas, Ohio, England and France. Each branch is served 
by its own sales force as well as manufacturing, warehouse and office 
facilities. Each branch is responsible for a broad geographic area. Branch 
managers have significant autonomy, which includes setting sales and 
marketing strategies. Each domestic branch is an independent profit center 
with a cash profit sharing bonus program based on its own performance. At 
the same time, the domestic branches closely integrate their manufacturing 
activities to enhance product availability. Branch sales forces in the U.S. 
are supported by marketing managers in the home office in Pleasanton, 
California. The sales force maintains close working relationships with 
customers, develops new business, calls on architects, engineers and 
building officials and participates in a range of educational seminars.

Simpson Strong-Tie sells its products through an extensive distribution 
system comprising dealer distributors supplying thousands of retail 
locations nationwide, contractor distributors, home centers, manufacturers 
of engineered wood products, and specialized contractors such as roof 
framers. SST's DIY and dealer products are used to build projects such as 
decks, patio covers and shelf and bench systems. SST received C-Mark 
equivalency clearance from the Japanese building code authorities, which is 
expected to facilitate acceptance of its products into the Japanese market, 
and has increased the distribution of its products in Australia and Chile. 
The Company believes that SST's increasing diversification into new and 
growing markets has reduced its vulnerability to construction industry 
cycles.

Simpson Strong-Tie dedicates substantial resources to customer service. 
Every year, SST produces numerous publications and point-of-sale marketing 
aids to serve specifiers, distributors, retailers and users. These 
publications include SST's general catalog, as well as various specific 
catalogs, such as those for its epoxy products and the engineered wood and 
plated truss industries. The catalogs and publications describe the 
products and provide load and installation information. SST publishes a 
newsletter, Connector Update, providing technical, installation and other 
information, as well as publications addressing seismic and hurricane 
conditions and the DIY market. To serve users in the U.S. and elsewhere who 
do not speak English, SST employs bilingual sales people and prints some of 
its publications in other languages.

Simpson Strong-Tie's engineers not only design and test products, but also 
provide engineering support for customers. This support might range from 
the discussion of a load value in a catalog to testing a unique application 
for an existing product. SST's sales force communicates with customers in 
each of its marketing channels, through its publications, seminars and 
frequent calls.

Based on its communications with customers, Simpson Strong-Tie believes 
that its products are essential to its customers' businesses, and it is 
SST's policy to ship products ordered within a few days of receiving the 
order. Many of SST's customers are contractors that require rapid delivery 
of needed products. Home centers and dealers also require superior service, 
because of fluctuating demand. To satisfy these requirements, SST maintains 
high inventory levels, has redundant manufacturing capability and some 
multiple dies to produce the same parts, and maintains computer sales and 
inventory control and forecasting capability throughout its nationwide 
network of factories and warehouses. The Company also has special programs 
for contractors intended to ensure the prompt and reliable manufacture and 
delivery of custom products.

Simpson Strong-Tie believes that dealer and home center sales of SST 
products are significantly greater when the bins and racks at large dealer 
and home center locations are adequately stocked with appropriate products. 
Various retailers carry varying numbers of different SST products and SST's 
Retail Specialists are engaged in ongoing efforts to inform retailers about 
other SST products that can be used in their specific markets and to 
encourage them to add these products to better meet their customers' needs. 
Achieving these objectives requires teamwork and significant inventory 
commitments between SST and the distributors and retailers. Retail 
Specialists are playing a significant role in keeping the racks full and 
extending the product lines at the large dealer and home center level. They 
help retailers order product, set up merchandising systems, stock shelves, 
hold product seminars and provide SST with daily information that is used 
to improve service and product mix.


Simpson Dura-Vent

Overview

Simpson Dura-Vent's venting systems are used to vent gas furnaces and water 
heaters, gas fireplaces and stoves, wood burning stoves and pellet stoves. 
SDV's metal vents, chimneys and chimney liner systems exhaust the products 
of combustion to the exterior of the building and have been designed for 
ease of assembly and safe operation and to achieve a high level of 
performance. SDV produces and markets several hundred different venting 
products and systems.

In recent years, the abundant supply and clean burning characteristics of 
natural gas have gained public recognition, resulting in increased market 
share for gas appliances in the new construction and the appliance 
replacement markets. In addition, concern over energy conservation and 
environmental air quality has resulted in increased use of gas stoves and 
fireplaces rather than the traditional wood burning stoves and fireplaces. 
As a result, new venting systems, such as Direct-Vent, have been developed 
to address changes in appliance technology.

Simpson Dura-Vent's objective is to expand market share in all of its 
distribution channels, by entering expanding markets that address energy 
and environmental concerns. SDV's strategy is to capitalize on its 
strengths in new product development and its established distribution 
network and to continue its commitment to high quality and service. SDV 
operates manufacturing and warehouse facilities in California and 
Mississippi.

Products

Simpson Dura-Vent is a leading supplier of double-wall Type B Gas Vent 
systems, used for venting gas furnaces, water heaters, boilers and 
decorative gas fireplaces. SDV believes that there is significant potential 
in the gas fireplace market, because of the large number of fireplaces sold 
in the new construction market, the relative ease of installing side-wall 
vented gas fireplaces for the remodeling market and the trend from wood to 
gas as a result of environmental concerns and ease of operation.

Simpson Dura-Vent's Type B Gas Vent product line features heavy-duty 
quality construction and a twist-lock design that provides for fast and 
easy job-site assembly compared to conventional snap together designs. The 
twist-lock design has broader applications and has been incorporated into 
SDV's gas, pellet and direct vent product lines. Simpson Dura-Vent also 
markets a patented flexible vent connector, Dura/Connect, for use between 
the gas appliance flue outlet and the connection to the Type B Gas Vent 
installed in the ceiling. Dura/Connect eliminates the difficult and time 
consuming process of cutting, crimping and fitting galvanized steel vent 
connectors. Marketed to home centers and hardware stores, Dura/Connect 
offers a simple twist, bend and connect installation for water heaters and 
gas furnaces.

The wood stove industry has responded to air quality concerns with 
substantial reductions in wood stove particulate emissions. Simpson Dura-
Vent's Dura-Plus safety valve design, a patented chimney system for use 
with wood burning stoves, provides enhanced fire safety in the event of a 
creosote chimney fire. 

The growing gas fireplace market has evolved into two basic types of 
fireplace: top-vent fireplaces that are vented with the standard Type B Gas 
Vent and direct-vent fireplaces that use a special double-wall venting 
system. SDV's direct-vent system is designed not only to exhaust the flue 
products, but also to draw in outside air for combustion, an important 
feature in modern energy-efficient home construction. The direct-vent gas 
fireplace systems provide ease of installation, permitting horizontal 
through-the-wall venting or standard vertical through-the-roof venting. 
Simpson Dura-Vent has entered into OEM and distribution relationships with 
several large manufacturers of gas stoves to supply direct-vent venting 
products. Sales of Direct-Vent have been robust. In 1996, SDV expanded its 
direct-vent product line to include both co-axial and co-linear direct vent 
systems for venting gas stoves and gas inserts into existing masonry 
chimneys or existing factory-built metal chimneys. The recent trend from 
wood to gas stoves, while increasing competition for wood and pellet 
appliance venting products, is viewed as a significant opportunity for 
SDV's gas venting products.


New Product Development

Simpson Dura-Vent has gained industry recognition by offering innovative 
new products that meet changing needs of customers. SDV representatives 
serve on industry committees concerned with issues such as new appliance 
standards and government regulations. SDV's research and development 
expense for the three years ended December 31, 1998, 1997 and 1996, was 
$431,000, $323,000 and $287,000, respectively. SDV also maintains working 
relationships with research and development departments of major appliance 
manufacturers, providing prototypes for field testing and conducting tests 
in SDV's testing laboratory. SDV believes that such relationships provide 
competitive advantages. For example, SDV introduced the first direct vent 
system for the increasingly popular direct vent gas appliances. In 1998, 
SDV introduced a new line of vent caps for gas vent and gas relining 
products to improve the aesthetics of the visible portion of a venting 
system. SDV plans to extend the use of these vent caps to other product 
lines. In addition, SDV is currently developing a new double-wall insulated 
chimney system for use on wood and oil burning appliances.

Sales and Marketing

Simpson Dura-Vent's sales organization consists of a director of sales and 
marketing, a marketing communications manager, regional sales managers, and 
independent representative agencies. SDV markets venting systems for both 
gas and wood burning appliances through wholesale distributors in the 
United States, Canada and Australia to the HVAC (heating, ventilating and 
air conditioning) and PHC (plumbing, heating and cooling) contractor 
markets, and to fireplace specialty shop distributors. These customers sell 
to contractor and DIY markets. SDV also markets venting products to home 
center and hardware store chains. SDV has entered into OEM relationships 
with several major gas fireplace and gas stove manufacturers, which SDV 
believes are leaders in the direct-vent gas appliance market.

Simpson Dura-Vent responds to technological changes occurring in the 
industry through new product development and has developed a reputation for 
quality and service to its customers. To reinforce the image of quality, 
SDV produces extensive sales support literature and advertising materials. 
Recognizing the difficulty that customers and users may have in 
understanding new, complex venting requirements, SDV publishes a venting 
handbook to assist contractors, building officials and retail outlets with 
the science of proper venting. Advertising and promotional literature has 
been designed to be used by distributors and their customers, as well as 
home centers and hardware chains.

Manufacturing Process

The Company has concentrated on making its manufacturing processes as 
efficient as possible without  compromising quality or flexibility 
necessary to serve the needs of its customers. The Company has developed 
and uses automated manufacturing processes. The Company's innovative 
manufacturing systems and techniques have allowed it to control 
manufacturing costs, even while developing both new products and products 
that meet customized requirements and specifications. The Company's 
development of specialized manufacturing processes also has permitted 
increased operating flexibility and enhanced product design innovation.

The Company is committed to helping people build safer structures 
economically through the design, engineering and manufacturing of 
structural connector and related products. To this end, the Company has 
developed a quality management system that employs numerous quality-control 
procedures, such as computer-generated work orders, constant review of 
parts as they are produced and frequent quality testing. Since 1996, 
Simpson Strong-Tie's quality management system has been registered under 
ISO 9001, an internationally recognized set of quality-assurance standards. 
The Company believes that ISO registration is a significant asset in doing 
business with European companies and is becoming increasingly important to 
U.S. companies.


Simpson Strong-Tie operates manufacturing and warehouse facilities in 
California, Texas, Ohio, Florida, Connecticut, Illinois, Washington, 
British Columbia, Ontario, England, France and Chile. Most of SST's 
products are produced with a high level of automation, using progressive 
dies run in automatic presses making parts from coiled sheet steel often in 
excess of 100 strokes per minute. SST produces over 500 million product 
pieces per year. Over half of SST's products are individually bar coded, 
particularly the products that are sold to home centers. SST has 
significant press capacity and has some multiple dies for its high volume 
products because of the need to produce the product close to the customer 
and to provide backup capacity. The balance of production is accomplished 
through a combination of manual, blanking and numerically controlled (NC) 
processes which include robotic welders, lasers and turret punches. SST 
believes it is the only manufacturer in the connector industry using NC 
turret punches to manufacture a large variety of standard and special 
products. This capability allows SST to produce products with little 
redesign or set-up time, facilitating rapid turnaround for customers. New 
tooling is also highly automated. Dies are designed and produced using 
computer aided design (CAD) and computer aided machinery (CAM) systems. 
CAD/CAM capability enables SST to create multiple dies rapidly and design 
them to high standards. The Company is constantly reviewing its product 
line to reduce manufacturing costs and increase automation.

Simpson Dura-Vent operates manufacturing and warehouse facilities in 
California and Mississippi where it produces component parts for venting 
systems using NC-controlled punch presses equipped with high-speed 
progressive and compound tooling. SDV's vent pipe and elbow assembly lines 
are automated, to produce finished products efficiently from large coils of 
steel and aluminum. UPC bar coding and computer tracking systems provide 
SDV's industrial engineers and production supervisors with real-time 
productivity tools to measure and evaluate current production rates, 
methods and equipment.

Most of the Company's current and planned manufacturing facilities is 
located in a geographic region that has experienced major natural 
disasters, such as earthquakes, floods and hurricanes. For example, the 
1989 Loma Prieta earthquake in Northern California destroyed a freeway and 
caused other major damage within a few miles of the Company's facilities in 
San Leandro, California, and the earthquakes in Northridge, California, in 
January 1994, destroyed several freeways and numerous buildings in the 
region in which the Company's facilities in Brea are located. The Company 
does not carry earthquake insurance. Other insurance that it carries is 
limited and not likely to be adequate to cover all of the Company's 
resulting costs, business interruption and lost profits in the event of a 
major natural disaster in the future. If a natural disaster were to render 
one or more of the Company's manufacturing facilities totally or partially 
unusable, whether or not covered by insurance, the Company's business and 
financial condition could be materially and adversely affected.

Regulation

The design, capacity and quality of most of the Company's products and 
manufacturing processes are subject to numerous and extensive regulations 
and standards promulgated by governmental, quasi-governmental and industry 
organizations. Such regulations and standards are highly technical and 
complex and are subject to frequent revision. The failure of the Company's 
products or manufacturing processes to comply with any of such regulations 
and standards could impair the Company's ability to manufacture and market 
its products profitably and materially and adversely affect the Company's 
business and financial condition.

Simpson Strong-Tie's product lines are subject to Federal, state, county, 
municipal and other governmental and quasi-governmental regulations that 
affect product design, development, testing, applications, marketing, 
sales, installation and use. Most SST products are recognized by building 
code and standards agencies. Agencies that recognize Company products 
include the International Conference of Building Officials ("ICBO"), 
Building Officials and Code Administrators International ("BOCA"), Southern 
Building Code Congress International ("SBCCI"), The National Evaluation 
Service, the City of Los Angeles, Dade County, Florida, and the California 
Division of Architecture. These and other code agencies adopt various 
testing and design standards and incorporate them into their related 
building codes. For example, ICBO requirements are codified in the Uniform 
Building Code. The Uniform Building Code generally applies to construction 
in the Western United States. To be recognized by ICBO, SST products must 
conform to Uniform Building Code requirements. SST considers this 
recognition to be a significant marketing tool and devotes considerable 
effort to obtaining appropriate approvals for its products. SST believes 
that architects, engineers, contractors and other customers are less likely 
to purchase structural products that lack the appropriate code approval or 
acceptance, at least if code-accepted competitive products are available. 
SST's management actively participates in industry related professional 
associations to keep abreast of regulatory changes and to provide 
information to regulatory agencies.


Simpson Dura-Vent operates under a complex regulatory environment that 
includes appliance and venting performance standards related to safety, 
energy efficiency and air quality. Gas venting regulations are contained in 
the National Fuel Gas Code ("NFGC"), while safety and performance 
regulations for wood burning appliances and chimney systems are contained 
in a National Fire Protection Association standard ("NFPA 211"). Standards 
for testing gas vents and chimneys are developed by testing laboratories 
such as Underwriter's Laboratories ("UL") in compliance with the American 
National Standards Institute. Clean air standards for both gas and wood 
burning appliances are regulated by the EPA. Energy efficiency standards 
are regulated by the Department of Energy ("DOE") under the authority of 
the National Appliance Energy Conservation Act. Under this act, the DOE 
periodically reviews the necessity for increased efficiency standards with 
respect to gas furnaces. A substantial percentage of Simpson Dura-Vent's 
Type B Gas Vent sales are for gas furnace applications. Minimum appliance 
efficiency standards might be adopted that could negatively affect sales of 
Type B Gas Vents, which could materially and adversely affect the Company's 
operating results and financial condition. The standards and regulations 
contained in the NFGC and NFPA 211 are ultimately adopted by national 
building code organizations such as ICBO, BOCA and SBCCI. In turn, the 
various building codes are adopted by local municipalities, resulting in 
enforcement through the building permit process. Safety, air quality and 
energy efficiency requirements are enforced by local air quality districts 
and municipalities by requiring proper UL, EPA and DOE labels on appliances 
and venting systems.

Competition

The Company faces a variety of competition in all of the markets in which 
it participates. This competition ranges from subsidiaries of large 
national or international corporations to small regional manufacturers. 
While price is an important factor, the Company competes primarily on the 
basis of quality, breadth of product line, technical support, service, 
field support and product innovation. Simpson Strong-Tie competes with 
numerous companies and its competitors tend to be more regional than SST, 
but one distributes its products nationally.

The venting industry is highly competitive. Many of Simpson Dura-Vent's 
competitors have greater financial and other resources than SDV. SDV's 
principal competitors include the Selkirk Metalbestos Division of Eljer 
Industries Inc. (a subsidiary of U.S. Industries, Inc.), American Metal 
Products Co. (a subsidiary of Masco Corp.), Metal-Fab, Inc., Hart & Cooley, 
Inc. and the Air Jet Division of General Products Co. The Company believes 
that Metal-Fab, Inc., Hart & Cooley, Inc. and Air Jet tend to be more 
regional than SDV, and that they have smaller shares of the national market 
than SDV.

Raw Materials

The principal raw material used by the Company is steel, including 
stainless steel, and is generally ordered to specific American Society of 
Testing and Materials ("ASTM") standards. Other raw materials include 
aluminum, aluminum alloys and ceramic and other insulation materials, which 
are used by Simpson Dura-Vent, and cartons, which are used by both SST and 
SDV. The Company purchases raw materials from a variety of commercial 
sources. The Company's practice is to seek cost savings and enhanced 
quality by purchasing from a limited number of suppliers.

The steel industry is highly cyclical and prices for the Company's raw 
materials are influenced by numerous factors beyond the Company's control, 
including general economic conditions, competition, labor costs, import 
duties and other trade restrictions. The Company historically has not 
attempted to hedge against changes in prices of steel or other raw 
materials. The Company might not be able to increase its product prices in 
amounts that correspond to increases in raw materials prices without 
materially and adversely affecting its sales and profits. See "Item 7 - 
Management's Discussion and Analysis of Financial Condition and Results of 
Operations."

Patents and Proprietary Rights

The Company's subsidiaries own more than 80 U.S. and foreign patents, of 
which more than 70 cover products that they currently manufacture and 
market. Its subsidiaries have filed 12 U.S. and 43 foreign patent 
applications that are currently pending. These patents and patent 
applications cover various design aspects of the subsidiaries' products as 
well as processes used in their manufacture. The Company's subsidiaries are 
continuing to develop new potentially patentable products, product 
enhancements and product designs. Although the Company's subsidiaries do 
not intend to apply for additional foreign patents covering existing 
products, the Company is developing an international patent program to 
protect new products that its subsidiaries may develop.

The Company's subsidiaries hold 116 trademark registrations in the U.S. and 
foreign countries covering 56 trademarks, have 35 trademark registration 
applications pending in the U.S. and foreign countries covering 13 
trademarks, and use several other trademarks that they have not yet 
attempted to register.


The Company's ability to compete effectively with other companies depends 
in part on its ability to maintain the proprietary nature of its 
technology. There can be no assurance, however, as to the degree of 
protection afforded by these patents or the likelihood that patents will 
issue pursuant to pending patent applications. Furthermore, there can be no 
assurance that others will not independently develop the same or similar 
technology, develop around the patented aspects of any of the Company's 
products or proposed products, or otherwise obtain access to the Company's 
proprietary technology.

In addition to seeking patent protection, the Company also relies on 
unpatented proprietary technology to maintain its competitive position. 
Nevertheless, there can be no assurance that the Company will be able to 
protect its know-how or other proprietary information.

In attempting to protect its proprietary information, the Company expects 
that it may sometimes be necessary to prosecute lawsuits against 
competitors and others that the Company believes have infringed or are 
infringing the Company's rights. In such an event, the defendant may assert 
counterclaims to complicate or delay the litigation or for other reasons. 
If the Company were to be unable to maintain the proprietary nature of its 
significant products, the Company's business and financial condition could 
be materially and adversely affected.

Acquisitions and Expansion into New Markets

The Company's future growth, if any, may depend to some extent on its 
ability to penetrate new markets, both domestically and internationally. 
See "Industry and Market Trends" and "Business Strategy." Therefore, the 
Company may in the future pursue acquisitions of product lines or 
businesses. Acquisitions involve numerous risks, including difficulties in 
the assimilation of the operations and products of the acquired companies, 
the diversion of management's attention from other business concerns, risks 
of entering markets in which the Company has little or no direct prior 
experience, and the potential loss of key employees of the acquired 
company. In addition, future acquisitions by the Company may result in 
potentially dilutive issuances of equity securities, the incurring of 
additional debt, and amortization expenses related to goodwill and 
intangible assets, all of which could adversely affect the Company's 
profitability. If an acquisition occurs, no assurance can be given as to 
its effect on the Company's business or operating results. See "Item 7 - 
Management's Discussion and Analysis of Financial Condition and Results of 
Operations."

In addition, construction customs, standards, techniques and methods in 
international markets differ from those in the United States. Laws and 
regulations applicable in new markets for the Company are likely to be 
unfamiliar to the Company and compliance may be substantially more costly 
than the Company anticipates. As a result, it may become necessary for the 
Company to redesign products or to invent or design new products in order 
to compete effectively and profitably outside the United States or in 
markets that are new to the Company in the United States. The Company 
expects that significant time will be required for it to generate 
substantial sales or profits in new markets. 

Other significant challenges to conducting business in foreign countries 
include, among other factors, local acceptance of the Company's products, 
political instability, currency controls, changes in import and export 
regulations, changes in tariff and freight rates, and fluctuations in 
foreign exchange rates. There can be no assurance that the Company will be 
able to penetrate these markets or that any such market penetration can be 
achieved on a timely basis or profitably. If the Company is not successful 
in penetrating these markets within a reasonable time, it will be unable to 
recoup part or all of the significant investments it will have made in 
attempting to do so. See "Business Strategy" and "Industry and Market 
Trends."

In 1996, the Company purchased for approximately $1.0 million the assets of 
the Builders Products Division of MiTek Industries Ltd. ("MiTek") and 
entered into an agreement to supply MiTek with connector products in the 
UK. In addition, during the first quarter of 1997, the Company purchased 
three Canadian companies and a related U.S. company, the Isometric Group, 
which manufacture and distribute a line of mechanical anchors and related 
products, for approximately $7.7 million plus an earnout based on future 
sales increases through December 2000. Also during the first quarter of 
1997, the Company purchased, for approximately $1.7 million, the remaining 
66% equity in Patrick Bellion, S.A., a French manufacturer of connector 
products. See "Item 7 - Management's Discussion and Analysis of Financial 
Condition and Results of Operations - Liquidity and Sources of Capital."


Seasonality and Cyclicality

The Company's sales are seasonal, with operating results varying from 
quarter to quarter. With some exceptions, the Company's sales and income 
have historically been lower in the first and fourth quarters and higher in 
the second and third quarters of the year, as retailers and contractors 
purchase construction materials in the late spring and summer months for 
the construction season. In addition, demand for the Company's products and 
the Company's results of operations are significantly affected by weather 
conditions, such as unseasonably warm, cold or wet weather, which affect, 
and sometimes delay or accelerate, installation of certain of the Company's 
products. Political and economic events can also affect the Company's 
revenues. The Company has little control over the timing of customer 
purchases, and sales anticipated in one quarter may occur in another 
quarter, thereby affecting both quarters' results. In addition, the Company 
incurs significant expenses as it develops, produces and markets its 
products in anticipation of future orders. Products typically are shipped 
as orders are received, and accordingly the Company operates with little 
backlog. As a result, net sales in any quarter generally depend on orders 
booked and shipped in that quarter. A significant portion of the Company's 
operating expenses are fixed, and planned expenditures are based primarily 
on sales forecasts. If sales fall below the Company's expectations, 
operating results would be adversely affected for the relevant quarters, as 
expenses based on those expectations will already have been incurred. See 
"Item 7 - Management's Discussion and Analysis of Financial Condition and 
Results of Operations."

The Company's principal markets are in the building construction industry. 
That industry is subject to significant volatility as a result of 
fluctuations in interest rates, the availability of credit to builders and 
developers, inflation rates and other economic factors and trends, none of 
which is within the Company's control. Declines in commercial and 
residential construction may be expected to reduce the demand for the 
Company's products. The Company cannot provide any assurance that its 
business will not be adversely affected by future negative economic or 
construction industry performance or that future declines in construction 
activity or the demand for the Company's products will not have material 
adverse effects on the Company and its business and financial condition. 
See "Item 7 - Management's Discussion and Analysis of Financial Condition 
and Results of Operations."

Product Liability

The Company designs and manufactures most of its standard products and 
expects that it will continue to do so. The Company employs engineers and 
designers to design and test its products under development. In addition, 
the Company maintains a quality control system. The Company has on occasion 
found manufacturing flaws in its products. In addition, the Company 
purchases from third party suppliers raw materials, principally steel, and 
finished goods that are produced and processed by other manufacturers. The 
Company also has on occasion found flaws in raw materials and finished 
goods produced by others, some of which flaws have not been apparent until 
after the products were installed by customers. Many of the Company's 
products are integral to the structural soundness or fire safety of the 
buildings in which they are used. As a result, if any flaws exist in the 
Company's products (as a result of design, raw material or manufacturing 
flaws) and such flaws are not discovered and corrected before the Company's 
products are incorporated into structures, the structures could suffer 
severe damage (such as collapse or fire) and personal injury could result. 
To the extent that such damage or injury is not covered by the Company's 
product liability insurance, and if the Company were to be found to have 
been negligent or otherwise culpable, the Company and its business and 
financial condition could be materially and adversely affected by the 
necessity to correct such damage and to compensate persons who might have 
suffered injury.

Furthermore, in the event that a flaw is discovered after installation but 
before any damage or injury occurs, it may be necessary for the Company to 
recall products, and the Company may be liable for any costs necessary to 
retrofit the affected structures. Any such recall or retrofit could entail 
substantial costs and adversely affect the Company's reputation, sales and 
financial condition. The Company does not carry insurance against recall 
costs, and its product liability insurance may not cover retrofit costs.

No assurance can be given that claims will not be made against the Company 
with regard to damage or destruction of structures incorporating Company 
products resulting from a natural disaster. Any such claims, if asserted, 
could materially and adversely affect the Company.


Environmental, Health and Safety Matters

The Company is subject to environmental laws and regulations governing 
emissions into the air, discharges into water, and generation, handling, 
storage, transportation, treatment and disposal of waste materials. The 
Company is also subject to other Federal and state laws and regulations 
regarding health and safety matters. The Company's manufacturing operations 
involve the use of solvents, chemicals, oils and other materials that are 
regarded as hazardous or toxic and the use of complex and heavy machinery 
and equipment that can pose severe safety hazards (especially if not 
properly and carefully used). Some of the Company's products also 
incorporate materials that are hazardous or toxic in some forms (such as 
zinc and lead, which are used in some steel galvanizing processes). The 
Company believes that it has obtained all material licenses and permits 
required by environmental, health and safety laws and regulations in 
connection with the Company's operations and that its policies and 
procedures comply in all material respects with existing environmental, 
health and safety laws and regulations. It is possible that additional 
licenses or permits may be required, that the Company's policies and 
procedures might not comply in all respects with all such laws and 
regulations or, even if they do, that employees might fail or neglect to 
follow them in all respects, and that the Company's generation, handling, 
use, storage, transportation, treatment or disposal of hazardous or toxic 
materials, machinery and equipment might cause injury to persons or to the 
environment. In addition, properties occupied by the Company may be 
contaminated by hazardous or toxic substances and remedial action may be 
required at some time in the future. It is also possible that materials in 
certain of the Company's products could cause injury or sickness. Relevant 
laws and regulations could also be changed or new ones could be adopted 
that require the Company to obtain additional licenses and permits and 
cause the Company to incur substantial expense. Any such event or 
contamination could have a material adverse effect on the Company and its 
liquidity, results of operations and financial condition. See "Regulation."

Employees and Labor Relations

As of March 1, 1999, the Company had 1,429 full-time employees, of whom 
1,007 were hourly employees and 422 were salaried employees. The Company 
believes that its overall compensation and benefits for the most part 
exceed industry averages and that its relations with its employees are 
good.

The Company is dependent on certain key management and technical personnel, 
including Thomas J Fitzmyers, Stephen B. Lamson, Barclay Simpson and Donald 
M. Townsend. The loss of one or more key employees could have a material 
adverse effect on the Company. The Company's success will also depend on 
its ability to attract and retain additional highly qualified technical, 
marketing and management personnel necessary for the maintenance and 
expansion of the Company's activities. The Company faces strong competition 
for such personnel and there can be no assurance that the Company will be 
able to attract or retain such personnel.

A significant number of the Company's employees at two of the Company's 
major manufacturing facilities are represented by labor unions and are 
covered by collective bargaining agreements. Two of the Company's 
collective bargaining agreements at two of its California facilities were 
renegotiated in 1998. These agreements cover the Company's sheetmetal 
workers and its tool and die craftsmen in Brea. These two contracts were 
extended into 2001 and 2002, respectively. Two other contracts, covering 
tool and die craftsmen and sheetmetal workers in San Leandro, expire in 
June 1999 and July 2000, respectively. A work stoppage or interruption by a 
significant number of the Company's employees could have a material and 
adverse effect on the Company and its business and financial condition.

currently conducted and as planned through 1999. The manufacturing

anticipates that it may require additional facilities to accommodate 
possible future growth.

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELEATED STOCKHOLDER 
MATTERS.

The Company's Common Stock has been listed on the New York Stock Exchange 
("NYSE") under the symbol "SSD" since October 13, 1997. Prior to that time, 
the Common Stock was traded on the Nasdaq National Market tier of The 
Nasdaq Stock Market under the trading symbol "SMCO." The following table 
shows the range of high and low closing sale prices per share of the Common 
Stock as reported by The Nasdaq Stock Market or the NYSE, as applicable,

The Company estimates that as of March 1, 1999, approximately 2,950 persons 
owned shares of the Company's Common Stock either directly or through 
nominees.

The Company currently intends to retain its future earnings, if any, to 
finance operations and fund internal growth and does not anticipate paying 
cash dividends on the Company's Common Stock for the foreseeable future. 
Future dividends, if any, will be determined by the Company's Board of 
Directors, based on the Company's earnings, cash flow, financial condition 
and other factors deemed relevant by the Board of Directors. In addition, 
existing loan agreements require the Company to maintain Tangible Net Worth 
of $100.0 million plus 50% of net profit after taxes for each fiscal year 
ending after December 31, 1997. This requirement may limit the amount that 
the Company may pay out as dividends on the common stock. As of December 
31, 1998, the Company had a Tangible Net Worth of $158.2 million.

RESULTS OF OPERATIONS.

Certain matters discussed below are forward-looking statements that involve 
risks and uncertainties, certain of which are discussed in this and in other 
reports filed by the Company with the Securities and Exchange Commission. 
Actual results might differ materially from results suggested by any 
forward-looking statements in this report.

The following is a discussion and analysis of the consolidated financial 
condition and results of operations for the Company for the years ended 
December 31, 1998, 1997 and 1996, and of certain factors that may affect the 
Company's prospective financial condition and results of operations. The 
following should be read in conjunction with the Consolidated Financial 
Statements and related Notes appearing elsewhere herein.

Overview

Annual net sales of the Company increased 37.9% to $279.1 million in 1998 
from $202.4 million in 1996. The increase in net sales resulted primarily 
from increased geographic distribution and a broadening of the Company's 
customer base and product lines, both internally and through acquisitions. 
Net sales increased from 1996 to 1998 in all regions of the United States, 
with above average rates of growth in the California market. Expansion into 
overseas markets also contributed to the net sales growth over the last 
three years. During the year ended December 31, 1998, gross profit margin 
increased to 39.1%, from 38.5% in 1996. The increase since 1996 was due 
primarily to lower material costs as a percentage of net sales, LIFO gains 
recorded in 1997 and 1998 and lower overhead costs as a percentage of net 
sales. Income from operations as a percentage of net sales, increased to 
18.4% in 1998 from 16.1% in 1996.



Results of Operations

The following table sets forth, for the years indicated, the percentage of 
net sales of certain items in the Company's consolidated statements of 
operations.

Comparison of the Years Ended December 31, 1998 and 1997

Net Sales

Net sales increased 13.4% to $279.1 million in 1998 from $246.1 million in 
1997. Net sales of Simpson Strong-Tie's products increased 15.6% to $220.3 
million in 1998 from $190.6 million in 1997, while net sales of Simpson 
Dura-Vent's products increased by 5.8% to $58.8 million in 1998 from $55.5 
million in 1997. SDV accounted for approximately 21.1% of the Company's 
total net sales in 1998, a decrease from 22.6% in 1997. The increases in net 
sales at both SST and SDV resulted from increases in sales volume, with an 
overall decrease in average prices. The increase in net sales reflected 
sales growth throughout the United States, particularly in the Southeastern 
region of the country and in California. International sales also increased 
at an above average rate, a portion of which was related to the businesses 
purchased in March 1997. See "Item 1. Business. Acquisitions and Expansion 
into New Markets." Home centers and contractor distributors were the fastest 
growing connector sales channels. The growth rate of Simpson Strong-Tie's 
seismic and high wind and engineered wood product sales was strong. 
Anchoring Systems products also contributed significantly to the increase in 
net sales. Direct-Vent products led Simpson Dura-Vent's net sales with a 
strong growth rate as compared to the prior year, while sales of chimney and 
pellet stove products declined.

Gross Profit

Gross profit increased 12.6% to $109.0 million in 1998 from $96.8 million in 
1997. As a percentage of net sales, gross profit decreased to 39.1% in 1998 
from 39.3% in 1997. The small decrease was primarily due to increased labor 
costs, depreciation on factory equipment and other production costs, offset 
somewhat by a slightly larger LIFO gain recorded in 1998 as compared to 
1997. 

Selling Expense

Selling expense increased 6.9% to $24.7 million in 1998 from $23.1 million 
in 1997, but decreased as a percentage of net sales to 8.9% in 1998 from 
9.4% in 1997. The increase in selling expense was primarily due to higher 
promotional expenses as well as higher costs related to the increase in the 
number of sales and marketing personnel, due in part to expenses associated 
with the expansion of the Anchoring Systems product line and introduction of 
the Strong-Wall product line.



General and Administrative Expense

General and administrative expenses increased 9.5% to $32.9 million in 1998 
from $30.1 million in 1997, but  decreased as a percentage of net sales to 
11.8% in 1998 from 12.2% in 1997. The increase in these expenses was 
primarily due to increased cash profit sharing, which resulted from higher 
operating profit.

Acquired European Operations

The Company recorded an after-tax net loss in its combined European 
operations of $2.3 million in 1998, including $1.2 million in intercompany 
interest charges, compared to after-tax net losses of $2.4 million in 1997. 
These losses are primarily associated with the Company's UK operations. 
Depreciation on purchased capital equipment and administrative and other 
overhead costs incurred related to the growing operations contributed 
significantly to the losses. The Company expects the losses in the UK to 
continue through at least 1999.

Other Information

In 1999, in order to concentrate on more profitable product lines, the 
Company sold its metal shapes business, acquired in 1994, to an unrelated 
buyer. The Company will record a small loss on the sale of this product 
line.


Comparison of the Years Ended December 31, 1997 and 1996

Net Sales

Net sales increased 21.6% to $246.1 million in 1997 from $202.4 million in 
1996. Net sales of Simpson Strong-Tie's products increased 25.3% to $190.6 
million in 1997 from $152.1 million in 1996, while net sales of Simpson 
Dura-Vent's products increased by 10.3% to $55.5 million in 1997 from $50.3 
million in 1996. SDV accounted for approximately 22.6% of the Company's 
total net sales in 1997, a decrease from 24.9% in 1996. The increases in net 
sales at both SST and SDV were primarily due to volume increases, with 
relatively small increases in average prices. The increase in net sales 
reflected sales growth throughout the United States, particularly in 
California and the Northeastern region of the country. International sales 
increased at a substantial rate, with a significant portion of this increase 
resulting from the businesses acquired earlier in the year. See "Item 1. 
Business. Acquisitions and Expansion into New Markets." Contractor 
distributors and home centers were the fastest growing connector sales 
channels. The growth rate of Simpson Strong-Tie's epoxy, seismic and 
engineered wood product sales remained strong, and SST's acquisition of the 
Isometric Group's line of mechanical anchor products also contributed 
significantly to the increase in net sales. Simpson Dura-Vent's sales of 
chimney products and Direct-Vent products experienced above-average growth.

Gross Profit

Gross profit increased 24.1% to $96.8 million in 1997 from $78.0 million in 
1996. As a percentage of net sales, gross profit increased to 39.3% in 1997 
from 38.5% in 1996. The increase was primarily due to a reduction as a 
percentage of net sales in the non-material components of cost of sales, 
including depreciation on factory equipment, research and development costs, 
labor, factory overhead costs and shipping and freight. These costs 
decreased as a percentage of net sales primarily due to the improved 
absorption of fixed components of these costs because of the increased sales 
volume. Material costs as a percentage of net sales also decreased slightly 
relative to 1996. These improvements were offset somewhat by a smaller LIFO 
gain recorded in 1997 as compared to 1996.

Selling Expense


Selling expense increased 15.0% to $23.1 million in 1997 from $20.1 million 
in 1996, but decreased as a percentage of net sales to 9.4% in 1997 from 
9.9% in 1996. The increase selling expense was primarily due to higher 
personnel costs, including agent commissions, related to the increase in the 
size of the sales force, which was expanded in 1997 to include 
manufacturers' representatives who distribute the Company's mechanical 
anchor product line. This increase was offset slightly by reduced spending 
on advertising and promotional materials.



General and Administrative Expense

General and administrative expenses increased 20.0% to $30.1 million in 1997 
from $25.0 million in 1996, but decreased as a percentage of net sales to 
12.2% in 1997 from 12.4% in 1996. The increase in these expenses was 
primarily due to increased cash profit sharing, which resulted from higher 
operating profit, as well as higher personnel costs, including those 
associated with the two acquisitions in March 1997. Partially offsetting the 
increase was a decrease in expenses because of the 1996 write-off of 
intangible assets related to Simpson Strong-Tie's operations in the UK.

Acquired European Operations

The Company recorded an after-tax net loss in its combined European 
operations of $2.4 million in 1997, including $1.0 million in intercompany 
interest charges, compared to after-tax net losses of $2.8 million in 1996. 
These losses are primarily associated with the Company's UK operations. 
Depreciation on purchased capital equipment and administrative and other 
overhead costs incurred related to the growing operations contributed 
significantly to the losses.


Liquidity and Sources of Capital

The Company's liquidity needs arise principally from working capital 
requirements, capital expenditures and asset acquisitions. During the three 
years ended December 31, 1998, the Company has relied primarily on 
internally generated funds to finance these needs. The Company's working 
capital requirements are seasonal with the highest working capital needs 
typically occurring in the second and third quarters of the year. Cash and 
cash equivalents were $37.4 million and $19.4 million at December 31, 1998 
and 1997, respectively. Working capital was $105.6 million and $83.3 million 
at December 31, 1998 and 1997, respectively. As of December 31, 1998, the 
Company had approximately $2.9 million in debt outstanding and had available 
to it unused credit facilities of approximately $22.1 million.

The Company had cash flows from operating activities of $34.5 million, $21.1 
million and $24.6 million for 1998, 1997 and 1996, respectively. In 1998, 
cash was provided by net income of $31.1 million, noncash expenses, such as 
depreciation and amortization, of $8.3 million and increases in trade 
accounts payable, income taxes payable and accrued profit sharing and 
commissions, totaling approximately $5.9 million. The Company's primary 
operating cash flow requirements resulted from increased levels of inventory 
and accounts receivable that were required as the Company's sales increased. 
In 1998, 1997 and 1996, the Company used cash of $11.0 million, $9.1 million 
and $7.7 million, respectively, to fund inventory and accounts receivable 
requirements. The balance of the cash used in 1998 resulted from changes in 
the other current asset and liability accounts.

Cash used in investing activities was $20.0 million, $21.8 million and $12.3 
million for 1998, 1997 and 1996, respectively. Capital expenditures, related 
primarily to expanding capacity, increased in 1998 to $20.1 million from 
$16.5 million in 1997. In 1998, $8.6 million of such capital expenditures 
was used for real estate and related purchases.

Financing activities provided net cash of $3.4 million, $0.3 million and 
$0.5 million in 1998, 1997 and 1996, respectively. In 1998, cash was 
provided primarily by the issuance of debt used to build Simpson Dura-Vent's 
new facility in Vicksburg, Mississippi, as well as through the exercise of 
stock options by current and former employees of the Company.

The Company believes that cash generated by operations, borrowings available 
under its existing credit agreements, the majority of which have been 
renewed through June 2000, and other available financing will be sufficient 
for the Company's working capital needs and planned capital expenditures 
through at least 1999.



Year 2000 Problem

The year 2000 problem is primarily the result of computer programs and 
computer controlled equipment using two digits rather than four to define 
the applicable year. Such software may recognize a date using "00" as the 
year 1900 rather than the year 2000. This could potentially result in system 
failures or miscalculations leading to disruptions in the Company's 
activities or those of its significant customers, suppliers and banks. 

The Company does not produce or sell any computer components, software or 
electronic parts in its normal business environment and, therefore, does not 
believe that it has any material risk of product liability or obsolescence 
resulting from the year 2000 problem.

In 1998, the Company established a Year 2000 Committee (the "Committee") to 
evaluate the extent, if any, of its year 2000 and associated problems, to 
make any required changes and to establish contingency plans. The Company's 
computer systems are PC based with few interfaces to other internal systems. 
These systems use a date handling routine that the Company believes to be 
year 2000 compliant. The Company has completed tests of its internal 
software which demonstrated no significant risk from the year 2000 problem.

The Company is also focusing on major customers, suppliers and equipment 
used in its operations to assess compliance. The Committee will continue to 
evaluate these areas of exposure and, where possible, will develop 
contingency plans and alternative sources to avoid interruptions in the 
Company's business. Nevertheless, the Company cannot give any assurance that 
there will not be a material adverse effect on the Company if third parties 
with whom the Company conducts business do not adequately address the year 
2000 problem and, therefore, are unable to conduct operations without 
interruption. 

Costs related to the year 2000 problem are funded through operating cash 
flows. The Committee estimates that the costs of addressing the year 2000 
problem are expected to be less than $100,000, of which approximately 75% 
has been spent. The Company presently expects that the total cost of 
achieving year 2000 compliant systems will not be material to its financial 
condition, liquidity or results of operations.

Time and cost estimates are based on currently available information. 
Developments that could affect estimates include, but are not limited to, 
the availability and cost of trained personnel, the ability to locate and 
correct all relevant computer code and systems, and the degree of 
remediation success of the Company's customers, suppliers and banks in 
finding and resolving their year 2000 problems.


Inflation

The Company believes that the effect of inflation on the Company has not 
been material in recent years, as inflation rates have remained low.

                  these consolidated financial statements.


              SIMPSON MANUFACTURING CO., INC. AND SUBSIDIARIES
                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.  Operations and Summary of Significant Accounting Policies

Nature of Operations

Simpson Manufacturing Co., Inc., through its subsidiaries Simpson Strong-Tie 
Company Inc. and Simpson Dura-Vent Company, Inc. and its other subsidiaries 
(collectively, the "Company"), designs, engineers and manufactures wood-to-
wood, wood-to-concrete and wood-to-masonry connectors and venting systems 
for gas and wood burning appliances and markets its products to the 
residential construction, light industrial and commercial construction, 
remodeling and do-it-yourself markets.

The Company operates exclusively in the building products industry segment. 
The Company's products are sold primarily throughout the United States of 
America. Revenues have some geographic market concentration on the west 
coast. A portion of the Company's business is therefore dependent upon 
economic activity within this region and market.

Use of Estimates

The preparation of financial statements in conformity with generally 
accepted accounting principles requires management to make estimates and 
assumptions that affect the reported amounts of assets and liabilities and 
disclosure of contingent 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.

Principles of Consolidation

The consolidated financial statements include the accounts of Simpson 
Manufacturing Co., Inc. and its subsidiaries. Investments in less than 50% 
owned affiliates are accounted for using the equity method. All significant 
intercompany transactions have been eliminated. 

Cash Equivalents

The Company considers all highly liquid investments with an original 
maturity of three months or less to be cash equivalents.

Short-term Investments

The Company considers investments with an original maturity of more than 
three months but less than one year to be short-term investments, which are 
categorized as "held-to-maturity" and carried at amortized cost, which 
approximates market value.

Inventory Valuation

Inventories are valued at the lower of cost or market, with cost determined 
under the last-in, first-out (LIFO) method, except in Europe and Canada, 
where inventories of approximately $5,553,000 and $4,782,000 at December 31, 
1998 and 1997, respectively, are valued using the first-in, first-out (FIFO) 
method.

Property, Plant and Equipment

Property, plant and equipment is carried at cost. Major renewals and 
betterments are capitalized; maintenance and repairs are expensed on a 
current basis. When assets are sold or retired, their costs and accumulated 
depreciation are removed from the accounts; the resulting gains or losses 
are reflected in the consolidated statements of operations. 




Depreciation and Amortization

Depreciation of property, plant and equipment is provided for using 
accelerated methods over the following estimated useful lives: 

     Factory machinery and equipment                     5 to 10 years
     Automobiles, trucks and other equipment             3 to 10 years
     Office equipment                                    3 to  8 years
     Buildings and site improvements                    20 to 45 years

Leasehold improvements are amortized using the straight-line method over the 
remaining term of the lease. 

Product Research and Development Costs

Product research and development costs, which are included in cost of sales, 
were charged against income as incurred and approximated $1,518,000, 
$1,280,000 and $1,312,000 in 1998, 1997 and 1996, respectively. 

Tooling Costs

Tool and die costs are included in product costs in the year incurred. 

Income Taxes

Income taxes are calculated using an asset and liability approach. The 
provision for income taxes includes federal and state taxes currently 
payable and deferred taxes, due to temporary differences between the 
financial statement and tax bases of assets and liabilities. In addition, 
the future tax benefits are recognized to the extent that realization of 
such benefits is more likely than not.

Foreign Currency Translation

The local currency is the functional currency of the Company's operating 
branches in Europe and Canada. Assets and liabilities denominated in foreign 
currencies are translated using the exchange rate on the balance sheet date. 
Revenues and expenses are translated using average exchange rates prevailing 
during the year. The translation adjustment resulting from this process is 
shown separately as a component of shareholders' equity. Foreign currency 
transaction gains or losses are included in the determination of net income.

Common Stock

Subject to the rights of holders of any Preferred Stock that may be issued 
in the future, holders of Common Stock are entitled to receive such 
dividends, if any, as may be declared from time to time by the Board of 
Directors (the "Board") out of funds legally available therefor and in the 
event of liquidation, dissolution or winding-up of the Company, to share 
ratably in all assets available for distribution. The holders of Common 
Stock have no preemptive or conversion rights. Subject to the rights of any 
Preferred Stock that may be issued in the future, the holders of Common 
Stock are entitled to one vote per share on any matter submitted to a vote 
of the shareholders, except that, on giving notice as required by law and 
subject to compliance with other statutory conditions, shareholders may 
cumulate their votes in an election of directors, and each shareholder may 
give one candidate a number of votes equal to the number of directors to be 
elected multiplied by the number of shares held by such shareholder or may 
distribute such shareholder's votes on the same principle among as many 
candidates as such shareholder thinks fit. There are no redemption or 
sinking fund provisions applicable to the Common Stock.

Preferred Stock

The Board has the authority to issue the authorized and unissued Preferred 
Stock in one or more series with such designations, rights and preferences 
as may be determined from time to time by the Board. Accordingly, the Board 
is empowered, without shareholder approval, to issue Preferred Stock with 
dividend, liquidation, conversion, voting or other rights that could 
adversely affect the voting power or other rights of the holders of the 
Company's Common Stock. 


Net Income per Common Share

Basic net income per common share is computed based upon the weighted 
average number of common shares outstanding. Common equivalent shares, using 
the treasury stock method, are included in the diluted per-share 
calculations for all periods when the effect of their inclusion is dilutive.

The following is a reconciliation of basic earnings per share ("EPS") to 
diluted EPS:

Comprehensive  Income

Comprehensive income, which is included in the consolidated statement of 
shareholders' equity, is defined as net income and other comprehensive 
income. Other comprehensive income includes changes in foreign currency 
translation adjustments recorded directly into shareholders' equity.

Concentration of Credit Risk

Financial instruments which potentially subject the Company to 
concentrations of credit risk consist of cash in banks, short-term 
investments in U.S. Treasury instruments and trade accounts receivable. The 
Company maintains its cash in demand deposit and money market accounts held 
primarily by two banks.

Adoption of Statements of Financial Accounting Standards

In June 1998, the Financial Accounting Standards Board issued Statements of 
Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative 
Instruments and Hedging Activities." SFAS No. 133 establishes standards 
affecting the accounting for derivative instruments and hedging activities. 
This standard is not expected to have a significant effect on the Company's 
operating results, financial condition or disclosures. SFAS No. 133 is 
effective for financial statements issued for periods beginning after June 
15, 1999, and accordingly, management has not determined the effect, if any, 
on the Company's financial statements.


Reclassifications

Certain prior year amounts have been reclassified to conform to the 1998 
presentation with no effect on net income as previously reported.


2. Acquisitions

In March 1997, the Company and its subsidiaries completed two acquisitions. 
The first was a purchase of three Canadian companies and a related U.S. 
company, the Isometric Group, which manufacture and distribute a line of 
mechanical anchors and related products. The acquisition price was 
approximately $7.7 million plus an earnout based on future sales increases 
through December 2000. The second was the purchase, for approximately $1.7 
million, of the remaining 66% equity in Patrick Bellion, S.A., a French 
manufacturer of connector products.



In December 1996, Simpson Strong-Tie International, Inc. ("SSTI"), a 
subsidiary of the Company, purchased the assets, including $675,000 in 
equipment, of the Builders Products Division of MiTek Industries Ltd. 
("MiTek") for approximately $1,040,000. The remaining $365,000 of the 
purchase price represents the excess of the purchase price over the fair 
value of the assets acquired. In conjunction with the purchase of the 
assets, SSTI also agreed to supply MiTek and its customers with connector 
products. As a result of this acquisition, the Company determined that 
additional manufacturing space was needed and consolidated all of its UK 
facilities into a single location. In connection with this consolidation, 
the intangible assets associated with the MiTek acquisition, the Truline 
Group Ltd. acquisition in 1995, and the Stokes of Cannock Ltd. acquisition 
in 1994, were written off during 1996.


3.  Trade Accounts Receivable

Trade accounts receivable consist of the following:

subsidiaries. At December 31, 1998, the Company had three outstanding 
standby letters of credit. Two of these letters of credit, in the aggregate 
amount of $667,995, were used to support the Company's self-insured workers'

was used to guarantee performance on the Company's leased facility in the 
UK. These letters of credit mature between June 1999 and June 2000. Other 
notes payable represent debt associated with foreign businesses acquired in 
March 1997.



9.  Commitments and Contingencies

Leases

Certain properties occupied by the Company are leased. The leases expire at 
various dates through 2012 and generally require the Company to assume the 
obligations for insurance, property taxes, and maintenance of the 
facilities. 

Some of the properties were leased from partnerships formed by certain 
current and former Company shareholders, directors, officers and employees. 
Rental expenses under these related party leases were as follows:

Rental expense for 1998, 1997 and 1996 with respect to all other leased 
property was approximately $2,285,000, $2,128,000 and $1,170,000, 
respectively. 

At December 31, 1998, minimum rental commitments under all noncancelable 
leases are as follows: 

          1999                           $  4,924,667

Some of these minimum rental commitments involve the related parties 
described above, contain renewal options, and provide for periodic rental 
adjustments based on changes in the consumer price index or current market 
rental rates.

The nominal term of Simpson Strong-Tie International, Inc.'s ("SSTI") lease 
in the United Kingdom is 25 years but includes an option to terminate 
without penalty in either the fifteenth or twentieth year upon one year 
written notice by SSTI. As such, future minimum rental payments associated 
with the first 15 years of this lease are included in minimum rental 
commitments in the table above.



Environmental

At two of the Company's operating facilities, evidence of contamination 
resulting from activities of prior occupants was discovered. The Company 
took certain remedial actions at one facility in 1990 and is monitoring the 
condition of this property to determine whether additional action, if any, 
may be required. The Company has been informed by the lessor of the other 
facility, Vicksburg Investors, that appropriate remedial action has been 
taken. The Company does not believe that either of these matters will have a 
material adverse effect on its financial position or results of operations.

Litigation

From time to time, the Company is involved in various legal proceedings and 
other matters arising in the normal course of business. 


10.  Income Taxes

The provision for income taxes consists of the following:

11.  Profit Sharing and Pension Plans

The Company has four profit sharing plans covering substantially all 
salaried employees and nonunion hourly employees. Two of the plans, covering 
U.S. employees, provide for annual contributions in amounts the Board of 
Directors may authorize, subject to certain limitations, but in no event 
more than the amount permitted under the Internal Revenue Code as deductible 
expense. The other two plans, covering the Company's European employees, 
require the Company to make contributions ranging from three to ten percent 
of the employee's compensation. The total cost for these four profit sharing 
plans for the years ended December 31, 1998, 1997 and 1996, was 
approximately $3,078,000, $2,775,000 and $2,469,000, respectively.

The Company also contributes to various industry-wide, union-sponsored 
defined benefit pension funds for union, hourly employees. Payments to these 
funds aggregated approximately $809,000, $708,000 and $667,000 for the years 
ended December 31, 1998, 1997 and 1996, respectively. 


12.  Related Party Transactions

The Chairman and the President and Chief Executive Officer of the Company, 
who are directors and principal shareholders of the Company, served as 
directors and officers of the Simpson PSB Fund (a charitable organization) 
until October 1997. The Company contributed $75,496, $207,156 and $50,000 to 
this organization in 1998, 1997 and 1996, respectively. The Chairman and the 
President and Chief Executive Officer of the Company were again appointed as 
directors and officers of the Simpson PSB Fund in January 1999.

Refer to Note 9 regarding related party transactions involving Company 
leases. 



13.  Stock Bonus and Stock Options Plans

The Company applies Accounting Principles Board Opinion 25, Accounting for 
Stock Issued to Employees, and related interpretations in accounting for its 
stock option plans. Accordingly, no compensation cost has been recognized 
for its non-qualified stock option plan as stock options granted under this 
plan have an exercise price equal to 100% of the market price on the date of 
grant. If the compensation cost for this plan had been determined based on 
the fair value at the grant dates for awards consistent with the method of 
SFAS No. 123, the pro forma effect on the Company's net income and earnings 
per share in 1998, 1997 and 1996 would have been:

The fair value of each option granted was estimated on the date of grant 
using the Black-Sholes option-pricing model with the following assumptions 
for 1998, 1997 and 1996, respectively: risk-free interest rate of 4.63 for 
1998 and 5.50% for 1997 and 1996; no dividend yield for all years; expected 
lives of 6.3, 6.3 and 6.1 years; and volatility of 30.7% for all years. The 
weighted average fair value per share of options granted during 1998, 1997 
and 1996 was $15.09, $14.12 and $9.63, respectively.

The Company currently has two stock option plans. The first is principally 
for the Company's employees and the second is for the Company's independent 
directors. During the last three years, the Company met most of the 
operating goals established for its two stock option plans and accordingly, 
has committed to grant options to purchase 118,750 shares for 1998 and has 
granted options to purchase 122,750 and 119,750 shares for 1997 and 1996, 
respectively. These options have an exercise price range of $36.63 to $41.18 
per share, $33.31 to $37.31 per share and $23.00 to $29.25 per share for 
1998, 1997 and 1996, respectively.

The Company also maintains a Stock Bonus Plan whereby for each ten years of 
continuous employment with the Company each employee who does not 
participate in one of the Company's stock option plans receives 100 shares 
of common stock. In 1998, 1997 and 1996, the Company committed to issue 
3,200, 5,100 and 4,500 shares, respectively, which resulted in compensation 
charges of $203,500, $305,038 and $180,155, respectively. The shares are 
issued in the year following the year in which they are earned.


14.  Segment Information

The Company is organized into two primary segments. The segments are defined 
by types of products manufactured, marketed and distributed to the Company's 
customers. The two product segments are construction connector products and 
venting products. These segments are differentiated in several ways, 
including the types of materials used, the production process, the 
distribution channels used and the applications in which the products are 
used. Transactions between the two segments were immaterial for each of the 
years presented.

The following table illustrates certain measurements used by management to 
assess the performance of the segments described above as of December 31 or 
for the years ended December 31, 1998, 1997 and 1996:

Cash collected by the Company's subsidiaries is routinely transferred into 
the Company's cash management accounts, and therefore, has been included in 
the total assets of the segment entitled "All Other." Cash and short-term 
investment balances in this segment were approximately $36,433,000, 
$18,096,000 and $23,200,000 as of December 31, 1998, 1997 and 1996,
