To our stockholders, customers and employees:

We at Simpson Manufacturing Co., Inc., through our subsidiary
Simpson Strong-Tie Company Inc., have a clear mission:

At Simpson Strong-Tie, we believe in doing what’s right for our
people, customers and community. As the trusted brand and
manufacturer for construction solutions, we thrive on helping
customers solve problems every day. We are all committed to
bringing added value and to exceeding expectations with our
promise of “No Equal” performance.

This mission drives us to perform at the highest level every day.

Our Strategy
Guided by our mission, we are focused on strategic growth through
diversification. We are achieving growth organically and through
acquisitions that leverage our engineering, testing, manufacturing and
distribution strengths. This growth has increased our product offering
and revenue and continues to reduce our dependence on North
American residential construction.

Capital Allocation Plan
Our capital allocation strategy is continually evaluated to ensure
a balance between capital expenditures, acquisitions, dividends
and share repurchases in order to create the most value for our
stockholders.

2015 Highlights
2015 was a year of gradual yet steady growth. By staying focused on
our long-range global strategy, our dedicated employees allowed us
to reinforce our strong position across the construction markets we
serve while expanding our branch presence and customer service.
Our emphasis on lean initiatives enabled us to continue to reduce
costs and improve efficiency across the company. Our operating
expenses as a percentage of sales decreased by 0.8% over 2014.

In March, we decided to close our sales offices in China, Dubai
and Thailand due to continued losses in these operations. This
decision was based on several factors, primarily the difficulty of
differentiating our products and our brand in these markets, which
sell predominantly on price.

In July, we announced that we will be combining two leased chemical
facilities into a newly acquired facility in West Chicago. We anticipate
greater efficiencies with one chemical manufacturing facility, and the
new location provides additional space for state-of-the art research
and testing capabilities and for future growth.

WE BUILD SAFETY

12 | Simpson Manufacturing Co., Inc.

At Simpson Strong-Tie, we’re continually developing
new structural solutions that help fortify and strengthen
the frames of homes and buildings — making them
stronger and safer against natural disasters.

FROM MOTHER NATURE

We work very hard to create products that exceed the
highest performance standards and building codes. Our
connectors, prefabricated wood and steel Strong-Wall®
shearwalls, and Strong-Rod™ continuous rod tiedown
systems help homes and buildings stand firm against
earthquakes and high winds.

And products like our Strong Frame® special moment
frame help structures absorb the shock of seismic
events and resist collapse, which ultimately saves lives.

As a company, we’re providing critical knowledge,
products and resources to help people and
communities build strong.

2015 Annual Report | 13

THIS IS SMART

Building strong also means building smart. By providing a large selection of
web, mobile and desktop software apps and an educational video library
to engineers and builders, we’re not just increasing the quality and speed
of their estimates, calculations and designs across applications. We’re also
sharpening their competitive edge and saving them time and resources.
Whether our customers need to analyze a series of complex loads and design
conditions, select the most appropriate anchor for their project, or connect
with our retail dealers, our software helps customers build strong and smart.

by natural disasters — assessing damage to homes
and buildings both here in the U.S. and abroad. From
education scholarships and matching-gift programs
to assisting people in times of need, our company
works to build strong communities worldwide.

Item 1. Business.

Company Background

PART I

The Company, through its wholly owned subsidiary, Simpson Strong-Tie Company Inc., designs, engineers and is a leading
manufacturer of wood construction products, including connectors, truss plates, fastening systems, fasteners and pre-fabricated
lateral systems used in light-frame construction, and concrete construction products used for concrete, masonry, steel construction
and for concrete repair, protection and strengthening, including adhesives, chemicals, mechanical anchors, carbide drill bits, powder
actuated tools and fiber reinforced materials. The Company markets its products to the residential construction, light industrial
and commercial construction, remodeling and do-it-yourself (“DIY”) markets. The Company also provides engineering services
in support of some of its products and increasingly offers design and other software that facilitates the specification, selection and
use of its products. The Company believes that the Simpson Strong-Tie brand benefits from strong brand name recognition among
architects and engineers who frequently specify in building plans the use of the Company’s products. The Company has continuously
manufactured structural connectors since 1956.

Business Strategy

The Company attracts and retains customers by designing, manufacturing and selling products that are of high quality and
performance, easy to use and cost-effective for customers. The Company aims 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. The Company maintains high levels of inventory to operate with
little backlog and fill most customer orders 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 intends to continue efforts to increase market share in both the wood construction and concrete construction product
groups by:

• maintaining frequent contact with customers and private organizations that provide information to building code officials;
continuing to sponsor seminars to inform architects, engineers, contractors and building officials on appropriate use,
•
proper installation and identification of the Company’s products;
continuing to invest in mobile and web applications for customers, utilizing social media, blog posts and videos to
connect and engage with customers and to help them do their jobs more efficiently; and
continuing to diversify product offerings to be less dependent on residential housing.

•

The Company’s long-term strategy is to develop, acquire or invest in product lines or businesses that have the potential to increase
the Company’s earnings per share over time and that:

complement the Company’s existing product lines;
can be marketed through the Company’s existing distribution channels;

•
•
• might benefit from use of the Company’s brand names and expertise;
•
•
•

are responsive to needs of the Company’s customers;
expand the Company’s markets geographically; and
reduce the Company’s dependence on the United States residential construction market.

New Products. The Company commits substantial resources to new product development. The majority of SST’s products have
been developed through its internal research and development program. SST’s research and development expense for the three
years ended December 31, 2015, 2014 and 2013, was $10.3 million, $11.2 million, and $10.7 million, respectively. The Company
believes it is the only United States manufacturer with the capability to test multi-story wall systems, thus enabling full scale
testing rather than analysis alone to prove system performance. The Company’s engineering, sales, product management, and
marketing teams work together with architects, engineers, building inspectors, code officials and customers in the new product
development process.

The Company’s product research and development is based largely on products or solutions that are identified within the Company
or as customers communicate to the Company as well as the Company’s strategic initiatives to develop new markets or product
lines. The Company’s strategy is to develop new products on a proprietary basis, to seek patents when appropriate and to rely on
trade secret protection for others. The Company typically develops 15 to 25 new products each year.
26

The Company expanded its product offering for 2015 by adding:

•
•
•
•
•
•

new connectors for wood framing applications;
new wood shrinkage compensating devices;
new cold formed steel bridging and kneewall connections;
new structural screws for wood, metal and composite decking applications;
new mechanical anchors were introduced for use in hollow wall conditions and for overhead applications; and
the repair, protection and strengthening line of products received code approvals for their carbon fiber fabric and
laminate systems.

The Company intends to continue to expand its product offering in all its products.

Distribution channels. 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 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 the Company’s products
that complement the mix of product offerings in their markets.

• Home Centers. The Company intends to increase penetration of the DIY markets by soliciting home centers and increasing
product offerings. The Company’s sales force maintains on-going contact with home centers to work with them in a broad
range of areas including inventory levels, retail display maintenance and product knowledge training. 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 has developed extensive bar coding and merchandising aids and has
devoted a portion of its research efforts to the development of DIY products. Compared to previous years, the Company’s
sales to home centers increased in 2015 and 2014, but declined in 2013. See “Item 1A — Risk Factors,” “Item 7 —
Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and “Note 13 — Segment
Information” to the Company’s Consolidated Financial Statements.

•

• Dealers. In some markets, the Company sells its products directly to lumber dealers and cooperatives.
• OEM Relationships. The Company works closely with manufacturers of engineered wood products and OEMs to develop
and expand the application and sales of its engineered wood connector and fastener products. The Company has
relationships with several of the largest manufacturers of engineered wood products.
International Sales. The Company has established a presence in the European Community through acquisition of
companies with existing customer bases and through servicing United States-based customers operating in Europe. The
Company also distributes connector, anchor and epoxy products in Mexico, Chile, Australia, New Zealand, South Africa
and the Middle East. The Company intends to continue to pursue and expand operations both inside and outside of the
United States (see “Note 13 — Segment Information” to the Company’s Consolidated Financial Statements). Sales of
some products may relate primarily to certain regions.

Operating Segments and Geographic Areas

The Company is organized into three operating segments consisting of the North America, Europe and Asia/Pacific segments. The
North America segment includes operations primarily in the United States and Canada. The Europe segment includes operations
primarily in France, the United Kingdom, Germany, Denmark, Switzerland, Portugal and Poland. The Asia/Pacific segment
includes operations primarily in Australia, New Zealand, South Africa, China, Taiwan, and Vietnam. These segments are similar
in several ways, including similarities in the products manufactured and distributed, the types of materials used, the production
processes, the distribution channels and the product applications. See “Note 13 — Segment Information” to the Company’s
Consolidated Financial Statements for information regarding the assets, revenue and performance of each of the Company’s
operating segments and geographic areas. Also see “Item 1A — Risk Factors.”

Products and Services

The Company manufactures and markets building and construction products and is a recognized brand name in residential and
commercial applications. The product lines historically have encompassed connectors, anchors, fasteners and lateral resistive
systems. In 2011 and 2012, the Company entered into the truss plate market and acquired repair and strengthening product lines
for the marine, industrial and transportation markets. See “Item 7 — Management’s Discussion and Analysis of Financial Condition
and Results of Operations,” and “Note 13 — Segment Information” to the Company’s Consolidated Financial Statements for
financial information regarding revenues by product category.

Most of the Company’s products are approved by building code evaluation agencies. To achieve such approvals, the Company
conducts extensive product testing, which is witnessed and certified by independent testing laboratories. The tests also provide
the basis of load ratings for the Company’s structural products. This test and load information is used by architects, engineers,
contractors, building officials and homeowners and is useful across all applications of the Company’s products, ranging from the
deck constructed by a homeowner to a multi-story structure designed by an architect or engineer.

Wood Construction Products. As described below, the Company’s wood construction products include (1) connectors, (2) truss
plates, (3) fastening systems and (4) lateral systems, and are typically made of steel. The Company produces and markets over
15,000 standard and custom wood construction products. These products are used primarily to strengthen, support and connect
wood joints in residential and commercial construction and DIY projects. The Company’s wood construction products contribute
to structural integrity and resistance to seismic, wind and other forces. Applications range from commercial and residential building,
to deck construction, to DIY projects.

1. The Company’s connectors are prefabricated metal products that attach wood, concrete, masonry or steel together.

Connectors are essential for tying wood construction elements together and create safer and stronger buildings.

2. The Company’s truss connector plates and software are marketed under the name Integrated Component Systems. Truss
plates are toothed metal plates that join wood members together to form a truss. The Company continues to develop
sophisticated software to assist truss and component manufacturers’ in modeling, designing trusses and selecting the
appropriate truss plates for the applicable jobs.

3. The Company’s fastener line includes various nails, screws and staples. Complimenting these products is the Quik Drive

auto-feed screw driving system used in numerous applications such as decking, subfloors, drywall and roofing.

4. The Company’s lateral resistive systems are assemblies used to resist earthquake or wind forces and include Strong-Wall

Shearwalls, ShearBrace, Anchor Tiedown Systems (“ATS”) and Special steel moment frames.

Concrete Construction Products. As described below, the Company’s concrete construction products include (1) anchor products,
and (2) construction repair, protection and strengthening products. The Company produces and markets over 2,000 standard and
custom concrete construction products. The Company’s concrete construction products are composed of various materials including
steel, chemicals and carbon fiber. They are used primarily to strengthen, anchor, support, repair and connect concrete joints in
residential and commercial construction and DIY projects used to repair, protect and strengthen concrete, brick and mortar
structures. The Company’s concrete construction products contribute to structural integrity and resistance to seismic, wind and
other forces. Applications range from industrial, commercial, infrastructure and residential structures, to DIY projects. These
products are sold in all segments of the Company worldwide.

1. The Company’s concrete construction anchor products include adhesives, mechanical anchors, carbide drill bits and
powder-actuated pins and tools used for numerous applications of anchoring or attaching elements onto concrete, brick,
masonry and steel.

2. The Company's concrete construction repair, protection and strengthening products include grouts, coatings, sealers,

mortars, fiberglass and fiber-reinforced polymer systems and asphalt products.

Engineering and Design Services. The Company’s engineers not only design and test products, but also provide engineering
support for customers in connection with a number of products that the Company manufactures and sells. This support might
range from the discussion of a load value in a catalog to testing the suitability of an existing product in a unique application. For
certain product lines, industry norms require that the Company’s engineers are more involved in the sales process. For example,
in connection with the sale of our truss plates, the Company’s engineers review the output of the Company’s software to assist
customers in ensuring that trusses are properly designed and specified, and in some instances stamp design diagrams. Generally,
in connection with any engineering services the Company provides, the Company’s engineers serve as a point of reference and
support for the customer’s engineers and other service professionals, who ultimately determine and are responsible for the
engineering approach to any project.

Sales and Marketing

The Company’s sales and marketing programs are implemented through its branch system. The Company currently maintains
branches in California, Texas, Ohio, Canada, England, France, Germany, Denmark, Switzerland, Poland, Czech Republic, Portugal,
Austria, The Netherlands, Australia, New Zealand, South Africa and Chile. Each branch is served by its own sales force, warehouse
and office facilities, while some branches have their own manufacturing facilities. Each branch is responsible for setting and
executing sales and marketing strategies that are consistent both with the markets in the geographic area that the branch serves
and with the goals of the Company. Branch sales forces in North America are supported by marketing managers in the home office
in Pleasanton, California. The home office also coordinates issues affecting customers that operate in multiple regions. 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.

The Company dedicates substantial resources to customer service. The Company produces numerous publications and point-of-
sale marketing aids to serve specifiers, distributors, retailers and users for the various markets that it serves. These publications
include general catalogs, as well as various specific catalogs, such as those for its fastener products. The catalogs and publications
describe the products and provide load and installation information. The Company also maintains several linked websites centered
on www.strongtie.com, which include catalogs, product and technical information, code reports and other general information
related to the Company, its product lines and promotional programs. The contents of these websites are not incorporated into this
filing. Further, the Company’s references to the URLs for these websites is intended to be inactive textual references only.

Manufacturing Process

The Company designs and manufactures most of its products. The Company has developed and uses automated manufacturing
processes for many of its products. 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 has also permitted increased operating flexibility and
enhanced product design innovation. As part of ongoing continuous improvement processes in its factories, the Company’s major
North American and European manufacturing facilities initiated lean manufacturing practices to improve efficiency and customer
service. The Company sources some products from third-party vendors, both domestically and internationally. The Company has
22 manufacturing locations in the United States, Canada, France, Denmark, Germany, Switzerland, Poland, Portugal, China and
England.

Quality Control. The Company has developed a quality system that manages defined procedures to ensure consistent product
quality and also meets the requirements of product evaluation reports of the International Code Council (ICC) and the International
Association of Plumbers and Mechanical Officials Uniform Evaluation Services (IAPMO-UES). Since 1996, the Company’s
quality system has been registered under ISO 9001, an internationally recognized set of quality-assurance standards. The Company
believes that ISO registration is a valuable tool for maintaining and promoting its high quality standards. As the Company establishes
new business locations through expansion or acquisitions, projects are established to integrate the Company’s quality systems and
achieve ISO 9001 registration. In addition, the Company has six testing laboratories accredited to ISO standard 17025, an
internationally accepted standard that provides requirements for the competence of testing and calibration laboratories. The
Company implements testing requirements through systematic control of its processes, enhancing the Company’s standard for
quality products, whether produced by the Company or purchased from others.

Wood Construction Products Manufacturing. Most of the Company’s wood construction products are produced with a high level
of automation. The Company has significant press capacity and has multiple dies for some of its high volume products to enable
production of these products close to the customer and to provide back-up capacity. The balance of production is accomplished
through a combination of manual, blanking and numerically controlled (NC) processes that include robotic welders, lasers and
turret punches. This capability allows the Company to produce products with little redesign or set-up time, facilitating rapid
turnaround for customers. The Company also has smaller specialty production facilities, which primarily use batch production
with some automated lines.

Concrete Construction Products Manufacturing. The Company manufactures its concrete construction products at its facilities
in Zhangjiagang, China, Addison, Illinois, Baltimore, Maryland, Cardet, France, Seewen, Switzerland, Malbork, Poland, and
Elvas, Portugal. The mechanical anchor products are produced with a high level of automation. Some products, such as epoxy
and adhesive anchors, are mixed in batches and are then loaded into one-part or two-part dispensers, which mix the product on
the job site because set-up times are usually very short. In addition, the Company purchases a number of products, powder actuated
pins, tools and accessories and certain of its mechanical anchoring products, from various sources around the world. These purchased
products undergo inspections on a sample basis for conformance with ordered specifications and tolerances before being distributed.

Regulation

Environmental Regulation. The Company itself 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 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. See “Item 1A — Risk Factors.”

Other. The Company’s product lines are subject to federal, state, county, municipal and other governmental and quasi-governmental
regulations that affect product development, design, testing, analysis, load rating, application, marketing, sales, exportation,
installation and use.

The Company considers product evaluation, recognition and listing to the building code as a significant tool that facilitates and
expedites the use of the Company’s products by design professionals, building officials, inspectors, builders, home centers and
contractors. Industry members are more likely to use building products that have the appropriate recognition and listing than
products that lack this acceptance. The Company devotes considerable time and testing resources to obtaining and maintaining
appropriate listings for its products. The Company actively participates in industry related professional associations and building
code committees both to keep abreast of regulatory changes and to provide comments and expertise to these regulatory agencies.

A substantial portion of the Company’s products have been evaluated and are recognized by governmental and product evaluation
agencies. Some of the entities that recognize the Company’s products include the International Code Council Uniform Evaluation
Service (ICC-ES), IAPMO-UES, the City of Los Angeles (LARR’s), California Division of the State Architect, the State of Florida,
Underwriters Laboratory (UL), Factory Mutual (FM) and state departments of transportation. In Europe, the Company’s structural
products meet European Technical Agreement (ETA) regulations.

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
also competes on the basis of quality, breadth of product line, proprietary technology, technical support, availability of inventory,
service (including custom design and manufacturing), field support and product innovation. As a result of differences in structural
design and building practices and codes, the Company’s markets tend to differ by region. Within these regions, the Company
competes with companies of varying size, several of which also distribute their products nationally or internationally. See “Item
1A — Risk Factors.”

Raw Materials

The principal raw material used by the Company is steel, including stainless steel. The Company also uses materials such as carbon
fiber, epoxies and acrylics in the manufacture of its chemical anchoring and reinforcing products. 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. The steel market continues to be dynamic, with a high degree of uncertainty about future pricing trends. Given
current conditions, including low demand, labor union contract negotiations, anti-dumping and countervailing duty trade cases
filed by United States steel producers in 2015, the Company currently expect that the high degree of uncertainty regarding steel
prices will continue. Numerous factors may cause steel prices to increase in the future. In addition to increases in steel prices,
mills may add surcharges for zinc, energy and freight in response to increases in their costs. See “Item 1A — Risk Factors” and
“Item 7 — Management’s Discussion and Analysis of Financial Condition and Results of Operations.” The Company historically
has not attempted to hedge against changes in prices of steel or other raw materials.

Patents and Proprietary Rights

The Company has United States and foreign patents, the majority of which cover products that the Company currently manufactures
and markets. These patents, and applications for new patents, cover various design aspects of the Company’s products, as well as
processes used in their manufacture. The Company continues to develop new potentially patentable products, product enhancements
and product designs. Although the Company does not intend to apply for additional foreign patents covering existing products,
the Company has developed an international patent program to protect new products that it may develop. In addition to seeking
patent protection, the Company relies on unpatented proprietary technology to maintain its competitive position. See “Item 1A
— Risk Factors.”

Acquisitions and Expansion into New Markets

The Company’s growth potential depends, to some extent, on its ability to penetrate new markets, both domestically and
internationally. See “Industry and Market Trends” and “Business Strategy.”

In December 2015, the Company purchased all of the business assets, including intellectual property, from Blue Heron Enterprises,
and Fox Chase Enterprises, LLC (collectively, "EBTY"), both New Jersey limited liability companies, for $3.4 million in cash.
EBTY manufactured and sold hidden deck clips and associated products and systems. The Company's provisional measurement
of assets acquired included goodwill of $2.0 million, which was assigned to the North American segment, and intangible assets
of $1.1 million, both of which are subject to tax-deductible amortization. Net assets consisting of inventory and equipment accounted
for the balance of the purchase price.

The Company currently intends as part of its expansion strategy to continue to pursue acquisitions of product lines or businesses.
See “Item 1A — Risk Factors” and “Item 7 — Management’s Discussion and Analysis of Financial Condition and Results of
Operations.”

Seasonality and Cyclicality

The Company’s sales are seasonal and cyclical. Operating results vary from quarter to quarter and with economic cycles. The
Company’s sales are also dependent, to a large degree, on the North American residential home construction industry. See “Item
1A — Risk Factors” and “Item 7 — Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Employees and Labor Relations

As of December 31, 2015, the Company had 2,498 full-time employees, of whom 1,029 were hourly employees and 1,469 were
salaried employees. The Company believes that its overall compensation and benefits for the most part meet industry averages
and that its relations with its employees are good.

A significant number of the employees at two of the Company’s facilities are represented by labor unions and are covered by
collective bargaining agreements. The Company’s facility in San Bernardino County, California, has two of the Company’s
collective bargaining agreements, one with tool and die craftsmen and maintenance workers, and the other with sheetmetal workers.
These two contracts expire February 2017 and June 2018, respectively. The Company’s facility in Stockton, California, is also a
union facility with two collective bargaining agreements, which also cover tool and die craftsmen and maintenance workers and
sheetmetal workers. These two contracts will expire July and September 2019, respectively. See “Item 1A — Risk Factors.”

Item 1A. Risk Factors.

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described
below, in addition to other information contained in this Annual Report on Form 10-K, including our consolidated financial
statements and related notes thereto, before you decide to buy or hold shares of our common stock. The risks and uncertainties
described below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently
believe are not material, may also become important factors that adversely affect our business. We may not be able to control any
of those risks and uncertainties. If any of those risks and uncertainties, whether described below or not, actually occurs, our
business, results of operations, financial condition and future prospects could be materially and adversely affected, and as a result,
any guidance that we may provide should not be relied on by investors. In such case, the trading price of our common stock could
decline, and you may lose all or part of your investment.

To facilitate a review of our risk factors, we have organized our risk factors into general groups of risks, including “General
Business Risks,” “Products, Services, and Sales Risks,” “Technological and Intellectual Property Risks,” “Regulatory Risks,”
“Capital Expenditures, Expansions, Acquisitions and Divestitures Risk,” “International Operations Risks,” “Capital Structure
and Stock Risks,” “Employee Risks,” and “Other Risks.” The grouping of risks is to facilitate your review only, and no ranking
of importance of risks or other inference should be made on account of such groups.

General Business Risks

Business cycles affect our operating results.

Our operating results and our stock price are heavily tied to the health of the building construction industry, with an
estimated 55% to 65% of our total product sales being dependent on housing starts. The construction industry is subject
to significant volatility due to real estate market cycles, fluctuations in interest rates, the availability, or lack thereof, of
credit to builders and developers, inflation rates, weather, and other factors and trends.

Further, many of our customers in the construction industry are small and medium-sized businesses. These businesses
are more likely to be significantly affected by economic downturns than larger, more established businesses. Uncertainty
about current global economic conditions may cause these consumers to postpone or refrain from spending or may cause
them to switch to lower-cost alternative products, which could reduce demand for our products and materially and
adversely affect our financial condition and operating results.

Further, declines in commercial and residential construction, such as housing starts and remodeling projects, which
generally occur during economic downturns, have in the past significantly reduced, and in the future can be expected to
reduce, the demand for our products and our stock price.

Our sales are seasonal and we have little control over the timing of customer purchases. If we miss seasonal
forecasts or customers purchase our products in different quarters than we or analysts expect, our stock could
materially decline.

Our sales are seasonal, with operating results varying from quarter to quarter. With some exceptions, our sales and income
have historically been lower in the first and fourth quarters than in the second and third quarters of the year, as customers
tend to purchase construction materials in the late spring and summer months for the construction season. In addition,
weather conditions, such as unseasonably warm, cold or wet weather, which affect, and sometimes delay or accelerate
installation of some of our products, significantly affect our results of operations. Sales that we anticipate in one quarter
may occur in another quarter, affecting both quarters’ results. If our operating results for a quarter are below the expectations
of analysts and investors, it could have a material adverse effect on our stock price.

In addition, we maintain high inventory levels and typically ship orders as we receive them, so we operate with little
backlog. The efficiency of our inventory system is closely tied to our ability to accurately predict seasonal and quarterly
variances. Further, our planned expenditures are also based primarily on sales forecasts. When sales do not meet our
expectations, our operating results will be reduced for the relevant quarters, as we will have already incurred expenses
based on those expectations. This could result in a material decline in our stock price.

We operate in a competitive industry, and if we fail to anticipate and react appropriately to competitors,
technological changes, changing industry trends and other competitive forces our revenue and profit margins will
decline.

Our ability to compete effectively depends upon our ability to meet changing market conditions and develop enhancements
to our products on a timely basis in order to maintain our competitive advantage. Many of our competitors have greater
financial and other resources than we do. Our continued growth will ultimately depend upon our ability to develop
additional products, services and technologies that meet our customers' expectation of our brand and quality. There can
be no assurance that we will be successful in developing and marketing new products, product enhancements and additional
technologies, that we will not experience difficulties that could delay or prevent the successful development, introduction
and marketing of these products, or that our new products and product enhancements will adequately meet the requirements
of the marketplace, or will achieve market acceptance.

Further, one of the core elements of our strategy is to provide high quality products and customer services. Many of our
competitors are dedicating increasing resources to competing with us, especially as our products become more affected

by technological advances and software innovations. Some of our competitors have more experience producing software
and other technology-driven solutions. As a result, we are dedicating increasing resources to research and development
in new and changing technologies in order to stay competitive and provide high quality and innovative products and
services. These increased expenditures could reduce our operating results.

Additionally, our ability to compete effectively depends, to a significant extent, on the specification or approval of our
products by architects, engineers, building inspectors, building code officials and customers and their acceptance of our
premium brand. If a significant segment of those communities were to decide that the design, materials, manufacturing,
testing or quality control of our products is inferior to that of any of our competitors or the cost differences between our
products and any competitors are not justifiable, our sales and profits would be materially reduced.

Any worldwide economic contraction will quickly affect our operating results.

Our business is materially affected by changes in regional, national or global economic conditions generally. Continuing
fluctuations in financial markets and the deterioration of national and global economic conditions have a profound effect
on the construction industry and may have materially adverse effects on our operations, financial results or liquidity,
including the following:

•

the financial stability of our customers or suppliers may be compromised, which could result in additional
bad debts for us or non-performance by suppliers;
financial instability of the financial institutions where we have our cash balances invested could result
in loss of our principal balance;
one or more of the financial institutions that make available our revolving credit facility may become
unable to fulfill their funding obligations, which could materially and adversely affect our liquidity;
it may become even more costly or difficult for us to obtain the agreed or additional financing or to
refinance our existing credit facility; and
our assets may be impaired or subject to write down or write off.

Product, Services and Sales Risks

Product liability claims, design defects, labeling defects, product formula defects, inaccurate chemical mixes and/
or product recalls could harm our reputation, sales and financial results.

We design and manufacture most of our standard products and expect to continue to do so, although we buy raw materials
and some manufactured products from others. We have on occasion found flaws and deficiencies in the design,
manufacturing, assembling, labeling, product formulations, chemical mixes or testing of our products. We also have on
occasion found flaws and deficiencies in raw materials and finished goods produced by others and used with or incorporated
into our products. Some flaws and deficiencies have not been apparent until after the products were installed by customers.

Many of our products are integral to the structural soundness or safety of the structures in which they are used. If any
flaws or deficiencies exist in our products and if such flaws or deficiencies are not discovered and corrected before our
products are incorporated into structures, the structures could be unsafe or could suffer severe damage, such as collapse
or fire, and personal injury could result. Errors in the installation of our products, even if the products are free of flaws
and deficiencies, could also cause personal injury and unsafe structural conditions. To the extent that such damage or
injury is not covered by our product liability insurance and we are held to be liable, we could be required to correct such
damage and to compensate persons who might have suffered injury, and our reputation, business and financial condition
could be materially and adversely affected.

Even if a flaw or deficiency is discovered before any damage or injury occurs, we may need to recall products (to the
extent possible), and we may be liable for any costs necessary to replace recalled products or retrofit or remedy the
affected structures. Any such recall, retrofit or other remedy could entail substantial costs and adversely affect our
reputation, sales and financial condition. We do not carry insurance against recall costs or the adverse business effect of
a recall, and our product liability insurance may not cover retrofit or other remedy costs.

As a result of the nature of many of our products and their use in construction projects, claims (including resulting from
a natural disaster) may be made against us with regard to damage or destruction of structures incorporating our products
whether or not our products failed. Any such claims, if asserted, could materially and adversely affect our business and
financial condition.

While we generally attempt to limit our liability under contracts and our exposure to price increases or comparable
expense increases, we may have uncapped liabilities or significant exposure under some contracts, and could suffer
material losses under such contracts.

We enter into many types of contracts with our customers, suppliers and other third parties, including in connection with
our expansion into new markets and new product lines. Under some of these contracts, our overall liability may not be
limited to a specified maximum amount or we may have significant potential exposure to price increases or to the need
to transition services to change service providers. If we receive claims under these contracts, are unable to successfully
transition when such contracts terminate, or experience significant price increases or comparable expense increases, we
may incur liabilities significantly in excess of the revenues associated with such contracts, which could have a material
adverse effect on our results of operations.

Our software provides some design functions to customers, and we increasingly are involved both in product sales
and engineering designs. Any software errors or deficiencies or failures in our engineering services could have
material adverse effects on our operations and financial condition.

Our design software increasingly facilitates the creation by customers of complex construction and building designs and
we increasingly are involved both in product sales and engineering designs. Our software is extremely complex and is
continually being modified and improved. As a result, it may contain defects or errors and new versions may introduce
new defects and errors. While we have attempted to limit our potential liability for the failure of any designs created by
our software, as a result of defects in our software or other defects outside of our control in the construction of structures
deigned by our software, the structures could be unsafe or could suffer severe damage, such as collapse or fire, and
personal injury could result. Errors in construction unconnected with our design could also cause personal injury and
unsafe structural conditions, even if our software design is sufficient. To the extent that a structure designed by our
software suffers any failure or deficiency, we could be required to correct deficiencies and may become involved in
litigation, even if our software design was not the cause of such deficiency. Further, if any damage or injury is not
covered by our insurance and we are held to be liable, we could be required to correct such damage and to compensate
persons who might have suffered injury, and our reputation, business and financial condition could be materially and
adversely affected.

While we engage in testing and upgrades, there can be no assurance that, despite our testing and upgrades, errors will
not be found in new and existing products resulting in loss of revenues or delay in market acceptance, diversion of
development resources, damage to our reputation, adverse litigation, or increased service and warranty costs, any of
which would have a material adverse effect upon our business, operating results and financial condition.

We are also increasingly involved in providing engineering solutions to our clients. The risks associated with providing
these services are materially different than the risks we historically faced when we only produced products. If our
engineers prepare, approve or seal drawings that contain defects or otherwise are involved in any design or construction
that contains flaws, regardless of whether our engineers caused such flaws, we may be held liable for professional
negligence or other damages, which could involve material claims.

We have a few large customers, the loss of any one of which could negatively affect our sales and profits.

Our largest customers accounted for a significant portion of net sales for the years ended December 31, 2015, 2014 and
2013, respectively. Any reduction in, or termination of, our sales to these customers would at least temporarily, and
possibly on a longer term basis, cause a material reduction in our net sales, income from operations and net income. Such
a reduction in or elimination of our sales to any of our largest customers would increase our relative dependence on our
remaining large customers.

In addition, our distributor customers have increasingly consolidated over time, which has increased the material adverse
effect of losing any one of them and may increase their bargaining power in negotiations with us. These trends could
negatively affect our sales and profitability.

Increases in prices of raw materials could negatively affect our sales and profits.

Our principal raw material is steel, including stainless steel. The steel industry can have large fluctuations. Numerous
factors beyond our control, such as general economic conditions, competition, worldwide demand, material and labor
costs, energy costs, foreign exchange rates, import duties and other trade restrictions influence prices for our raw materials.
Further, the domestic steel market is heavily influenced by three major United States manufacturers. We have not always

been able, and in the future we might not be able, to increase our product prices in amounts that correspond to increases
in costs of raw materials, without materially and adversely affecting our sales and profits.

We have historically not hedged against changes in prices of steel or other raw materials. In recent years, however, we
have increased our anticipatory purchases of steel in an effort to mitigate the effects of rising steel prices. This strategy,
coupled with changing economic conditions, has resulted in substantial fluctuations in our inventory in recent years,
which can materially and adversely affect our margins, cash flow and profits.

Technological and Intellectual Property Risks

Our recent efforts to increase our technology offerings and integrate new software and application offerings may
prove unsuccessful and may affect our future prospects.

Our industry has experienced increased complexity in some home design, and builders are more aggressively trying to
reduce their costs. One of our responses has been to design and market sophisticated software to facilitate the design and
marketing of our product systems. We have continued to commit substantial resources to our software development
endeavors in recent years and expect that trend to continue in 2016.

We have a limited operating history in the technology space and may not be able to create commercially successful
software and applications. Even if we are able to create initially successful ideas, the technology industry is subject to
rapid changes. We may not be able to adapt quickly enough to keep up with changing demands, and our software may
become obsolete.

While we see having a software interface with the construction industry as a potential growth area, we also face competition
from other companies that are focused solely or primarily on the development of software and applications. These
companies may have significantly greater expertise and resources to devote to software development, and we may be
unable to compete with them in that space. Even if we are successful in competing with such companies, we will likely
be required to expend significant resources and time and hire additional personnel to develop and maintain our software
offerings. This could increase our operating costs and reduce our profitability. On the other hand, if our software
development endeavors fail to generate profits, expended resources may not be recovered and our reputation, business,
operating results, and financial condition could be materially and adversely affected. For example, we wrote off $5.9
million for software development projects in 2015.

If we cannot protect our technology, we will not be able to compete effectively.

Our ability to compete effectively with other companies depends in part on our ability to maintain the proprietary nature
of our technology, in part through patents, copyrights, trade secrets and other intellectual property protections. We might
not be able to protect or rely on our patents and copyrights. Patents might not issue pursuant to pending patent applications.
Our software copyright and other protections might not be adequate to protect our software and application code. Others
might independently develop the same or similar technology, develop around the patented aspects of any of our products
or proposed products, or otherwise obtain access to or circumvent our proprietary technology. We also rely on unpatented
proprietary technology to maintain our competitive position. We might not be able to protect our trade secrets, our know-
how or other proprietary information. If we are unable to maintain the proprietary nature of our significant products, our
sales and profits are likely to be materially reduced.

In attempting to protect our proprietary information, we sometimes initiate lawsuits against competitors and others that
we believe have infringed or are infringing our rights. In such an event, the defendant may assert counterclaims to
complicate or delay the litigation or for other reasons. Litigation may be very costly and may result in adverse judgments
that affect our sales and profits materially and adversely.

Claims that we infringe intellectual property rights of others may materially increase our expenses and reduce
our profits.

Other parties have in the past and may in the future claim that our products or processes infringe their patent rights and
other intellectual property rights. We may incur substantial costs and liabilities in investigating, defending and resolving
such claims, whether or not they are meritorious, which may materially reduce our profitability and materially and
adversely affect our business and financial condition. Litigation can be disruptive to normal business operations and may
result in adverse rulings or decisions. If any such infringement claim is asserted against us, we may be required to obtain
a license or cross-license, modify our existing technology or design a new non-infringing technology, any of which could
35

be costly and time-consuming. A ruling against us in an infringement lawsuit could include an injunction barring our
production or sale of any infringing product. A damages award against us could include an award of royalties or lost
profits and, if the court finds willful infringement, treble damages and attorneys’ fees.

If we are unable to protect our information systems against data corruption, cyber-based attacks or network
security breaches, our operations could be disrupted and our reputation and profitability could be negatively
affected.

We depend on information technology networks and systems, including the internet, to process, transmit and store
electronic information. We depend on our information technology infrastructure for electronic communications among
our locations around the world and between our personnel and our subsidiaries, customers and suppliers. We collect and
retain large volumes of internal and customer, vendor and supplier data, including some personally identifiable
information, for business purposes. We also maintain personally identifiable information about our employees. The
integrity and protection of our customer, vendor, supplier, employee and other Company data is critical to our business.
The regulatory environment governing information, security and privacy laws is increasingly demanding and continues
to evolve. Maintaining compliance with applicable security and privacy regulations may increase our operating costs or
adversely affect our business operations.

Unauthorized parties may also attempt to gain access to our systems or facilities through fraud, trickery or other forms
of deceiving our employees, contractors and temporary staff. Security breaches of our infrastructure could create system
disruptions, shutdowns or unauthorized disclosures of confidential information. Despite the security measures we have
in place, our facilities and systems, and those of the retailers, dealers, licensees and other third party distributors with
which we do business, may be vulnerable to security breaches, cyber-attacks, acts of vandalism, computer viruses,
misplaced or lost data, programming and/or human errors or other similar events. Any security breach involving the
misappropriation, loss or other unauthorized disclosure of confidential customer, employee, supplier or Company
information, whether by us or by the retailers, dealers, licensees and other third party distributors with which we do
business, could result in losses, severely damage our reputation, expose us to the risks of litigation and liability, disrupt
our operations and have a material adverse effect on our business, results of operations and financial condition.

We also publicly post our privacy policies and practices concerning our processing, use, and disclosure of personally
identifiable information on our website. The publication of our privacy policy and other statements we publish that
provide assurances about privacy and security can subject us to potential federal, state, or other regulatory action if they
are found to be deceptive or misrepresentative of our practices.

Regulatory Risks

Failure to comply with industry regulations could result in reduced sales and increased costs.

We rely on the compliance of our products with regulations and specifications as one of our key competitive advantages.
The design, capacity and quality of most of our products and manufacturing processes are subject to numerous and
extensive regulations and standards promulgated by governmental, quasi-governmental and industry organizations. These
regulations and standards are highly technical, complex and subject to frequent revision. If our products or manufacturing
processes fail to comply with any regulations or standards or we fail to continue to innovate and update our products to
comply with changing regulations and standards, we may not be able to manufacture and market our products profitably
and may suffer damage to our brand and reputation, which could lead to declines in sales and the price of our stock.

Complying or failing to comply with environmental, health and safety laws and regulations could affect us
materially and adversely.

We are 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. We are also subject to other
federal and state laws and regulations regarding health and safety matters.

Our manufacturing operations involve the use of solvents, chemicals, oils and other materials that are regarded as hazardous
or toxic. We also use complex and heavy machinery and equipment that can pose severe safety hazards, especially if not
properly and carefully used. Some of our products also incorporate materials that are hazardous or toxic in some forms,
such as zinc and lead used in some steel galvanizing processes, chemicals used in our acrylic and epoxy anchoring
products, and chemicals used in our concrete repair, strengthening and protecting products. The gun powder used in our

powder-actuated tools is explosive. We have in the past, and may in the future, need to take steps to remedy our failure
to properly label, store, use and manufacture such toxic and hazardous materials.

If we do not obtain all material licenses and permits required by environmental, health and safety laws and regulations,
we may be subject to regulatory action by governmental authorities. If our policies and procedures do not comply in all
respects with existing environmental, health and safety laws and regulations, our activities might violate such laws and
regulations. Even if our policies and procedures do comply, but our employees fail or neglect to follow them in all respects,
we might incur similar liability. Relevant laws and regulations could change or new ones could be adopted that require
us to obtain additional licenses and permits and cause us to incur substantial expense.

Complying or failing to comply with conflict minerals regulations could materially and adversely affect our supply
chain, our relationships with customers and suppliers and our financial results.

We are currently subject to conflict mineral disclosure regulations in the U.S. and may be affected by potentially expansive
conflict mineral regulations that have been proposed in the European Union. While we have been successful to date in
adapting to such regulations, we have and will continue to incur added costs to comply with the disclosure requirements,
including costs related to determining the source of such minerals used in our products. We may not be able to ascertain
the origins of such minerals that we use and may not be able to satisfy requests from customers to certify that our products
are free of conflict minerals. These new requirements also could constrain the pool of suppliers from which we source
such minerals. We may be unable to obtain conflict-free minerals at competitive prices. Such consequences will increase
costs and may materially and adversely affect our manufacturing operations and profitability.

Capital Expenditures, Expansions, Acquisitions and Divestitures Risks

Our acquisition growth strategy presents unique risks for our business, and any acquisition could materially and
adversely affect our business and operating results.

We pursue acquisitions of product lines or businesses as one of our key growth strategies. We compete for acquisitions
with other potential acquirers, some of which have greater financial or operational resources than we do. As a result, we
may not be able to identify suitable acquisition candidates or strategic opportunities. Any acquisitions we undertake
involve numerous risks, including, for example:

•
•
•
•
•

•
•
•
•
•
•
•

inadequate access to information and/or due diligence of acquired businesses:
diversion of management’s attention from other business concerns;
overvaluation of acquired businesses;
difficulties assimilating the operations and products of acquired businesses;
inaccurate accounting or public reporting arising from integration of the financial statements and disclosures
of acquired businesses;
undisclosed existing or potential liabilities of acquired businesses;
slow acceptance or rejection of acquired businesses’ products by our customers;
risks of entering markets in which we have little or no prior experience;
litigation involving activities, properties or products of acquired businesses;
increased cost of regulatory compliance and enforcement;
consumer and other claims related to products of acquired businesses; and
the potential loss of key employees of acquired businesses.

In addition, future acquisitions may involve issuance of additional equity securities that dilute the value of our existing
equity securities, increase our debt, cause impairment related to goodwill and cause impairment of, and amortization
expenses related to, other intangible assets, which could materially and adversely affect our profitability. Any acquisition
could materially and adversely affect our business and operating results, and as a result, our business and operating results
may differ from any guidance that we may provide.

Significant costs to integrate our acquired operations may negatively affect our financial condition and the market
price of our stock.

We will incur costs integrating acquired business operations, products and personnel. These costs may be significant and
may include expenses and other liabilities for employee redeployment, relocation or severance, combining teams and
processes in various functional areas, reorganization or closures of facilities, and relocation or disposition of excess
equipment. The integration costs that we incur may negatively affect our profitability and the market price of our stock.
37

Further, integrating acquired business operations is time intensive, requiring significant commitment of our management
team’s focus and resources. If our management team spends too much time focused on recent acquisitions or on potential
acquisition targets, our management team may not have sufficient time to focus on our existing business and operations.
This diversion of attention could have material and adverse consequences on our operations and our ability to be profitable.

We may decide to dispose of assets and incur material expenses in doing so.

We have terminated in the past and may terminate in the future product lines or businesses if we determine that the cost
of operating them is not warranted by their expected profitability. For example, we terminated our heavy-duty mechanical
anchor systems business in Ireland and Germany in 2012, sold our CarbonWrap concrete construction assets in 2013 and
closed our sales offices in China, Thailand and Dubai in 2015. There are significant costs with such divestitures, which
could materially and adversely affecting our sales, assets, profitability and financial condition.

Our capital expenditures may not be adequate to maintain our competitive position and may not be implemented
in a timely or cost-effective manner.

Our capital expenditures are limited by our liquidity and capital resources and the amount we have available for capital
spending is limited by the need to pay our other expenses and to maintain adequate cash reserves and borrowing capacity
to meet unexpected demands that may arise. Productivity improvements through process re-engineering, design efficiency
and manufacturing cost improvements may be required to offset potential increases in labor and raw material costs and
competitive price pressures. If we are unable to make sufficient capital expenditures, or to maximize the efficiency of
the capital expenditures we do make, our competitive position may be harmed and we may be unable to manufacture the
products necessary to compete successfully in our targeted market segments.

Additional financing, if needed, to fund our working capital, growth or acquisitions may not be available on
reasonable terms, or at all.

If our cash requirements for working capital or to fund our growth increase to a level that exceeds the amount of cash
that we generate from operations and have available through our current credit arrangements, or if we should decide to
make an acquisition that requires more cash than we have available internally and through our current credit arrangements,
we will need to seek additional financing. Additional or new borrowings may not be available on reasonable terms, or at
all. Our ability to raise money by issuing and selling shares of our common or preferred stock depends on general market
conditions and the demand for our stock. If we sell stock, our existing stockholders could experience substantial dilution.
Our inability to secure additional financing could prevent the expansion of our business, internally and through
acquisitions.

If we change significantly the location, nature or extent of some of our manufacturing operations, we may reduce
our net income.

If we decide to change significantly the location, nature or extent of a portion of our manufacturing operations, we may
need to record an impairment of our goodwill. Our goodwill totaled $124.0 million at December 31, 2015. Recording an
impairment of our goodwill correspondingly reduces our net income. Other changes or events in the future could further
impair our recorded goodwill, which could also materially and adversely affect our profitability.

International Operations Risks

International operations expose us to foreign exchange rate risk.

We have foreign exchange rate risk in our international operations and through purchases from foreign vendors. We do
not currently hedge this risk. Changes in currency exchange rates could materially and adversely affect our sales and
profitability.

Our future growth may depend on our ability to penetrate new domestic and international markets, which could
reduce our profitability.

International construction, standards, techniques and methods differ from those in the United States. Laws and regulations
applicable in new markets may be unfamiliar to us. Compliance may be substantially more costly than we anticipate. As
a result, we may need to redesign products, or invent or design new products, to compete effectively and profitably in

new markets. We expect that we will need significant time, which may be years, 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 our products, political instability, changes in import and export regulations, changes in tariff and freight rates,
fluctuations in foreign exchange rates, currency controls, cash repatriation restrictions and differing economic outcomes.
We might not be able to penetrate these markets and any market penetration that occurs might not be timely or profitable.
If we do not penetrate these markets within a reasonable time, we will be unable to recoup part or all of the significant
investments we will have made in attempting to do so.

Because of our international operations, we could be adversely affected by violations of applicable U.S. federal
and state or foreign laws and regulations, such as the United States Foreign Corrupt Practices Act and similar
worldwide anti-bribery, anti-corruption and anti-kickback laws.

As a result of our expanded international operations, we face increasing compliance and regulatory oversight related to
operating in foreign markets. The foreign and U.S. laws and regulations that are applicable to our operations are complex
and may increase the costs of regulatory compliance, or limit or restrict the products or services we sell or subject our
business to the possibility of regulatory actions or proceedings. The United States Foreign Corrupt Practices Act, and
other similar laws and regulations, generally prohibit companies and their intermediaries from making improper payments
to foreign governmental officials for the purpose of obtaining or retaining business. While our policies mandate compliance
with applicable laws and regulations, including anti-bribery laws and other anti-corruption laws, we cannot assure you
that we will be successful in preventing our employees or other agents from taking actions in violation of these laws or
regulations. Such violations, or allegations of such violations, could disrupt our business and result in a material adverse
effect on our financial condition, results of operations and cash flows.

Our international operations may be materially and adversely affected by factors beyond our control.

Economic, social and political conditions, laws, practices and customs vary widely among the countries where we produce
or sell our products. Our operations outside of the United States are subject to a number of risks and potential costs,
including, for example, lower profit margins, less protection of intellectual property and economic, political and social
uncertainty in some countries. Our sales and profits depend, in part, on our ability to develop and implement policies and
strategies that effectively anticipate and manage these and other risks in the countries where we do business. These and
other risks may materially and adversely affect our operations in any particular country and our business as a whole.
Inflation in emerging markets also makes our products more expensive there and increases the market and credit risks
that we are exposed to.

Our international operations depend on our successful management of our subsidiaries outside of the United
States.

We conduct our international business through wholly owned subsidiaries. Managing distant subsidiaries and fully
integrating them into our business is challenging. We cannot directly supervise every aspect of the operations of our
subsidiaries operating outside the United States. As a result, we rely on local managers and staff. Cultural factors and
language differences can result in misunderstandings among internationally dispersed personnel. The risk that
unauthorized conduct may go undetected may be greater in subsidiaries outside of the United States. These problems
could adversely affect our sales and profits.

Failure to comply with export, import, and sanctions laws and regulations could affect us materially and adversely.

We are subject to a number of export, import and economic sanction regulations, including the International Traffic in
Arms Regulations (the “ITAR”), the Export Administration Regulations (the “EAR”) and U.S. sanction regulations
administered by the U.S. Department of Treasury, Office of Foreign Assets (“OFAC”). Foreign governments where we
have operations also implement export, import and sanction laws and regulations, some of which may be inconsistent
with ITAR and EAR.

If we do not obtain all necessary import and export licenses required by applicable export and import regulations, including
the ITAR and the EAR, or do business with sanctioned countries or individuals, we may be subject to fines, penalties
and other regulatory action by governmental authorities, including, among other things, having our export or import
privileges suspended. Even if our policies and procedures for exports, imports and sanction regulations comply, but our
employees fail or neglect to follow them in all respects, we might incur similar liability.

Any change in applicable export, import or sanction laws or regulations or any legal or regulatory violations could
materially and adversely affect our business and financial condition.

Our manufacturing facilities in China complicate our supply and inventory management.

We maintain manufacturing capability in various parts of the world, in part to allow us to serve our customers with prompt
delivery of needed products. Such customer service is a significant factor in our efforts to compete with larger companies
that have greater resources than we have. In recent years, we have substantially expanded our manufacturing in China.
Nearly all of our manufacturing output in China was and is currently intended for export to other parts of the world.
Because of the great distances between our manufacturing facilities in China and the markets to which the products made
there will be shipped, we may have difficulty providing adequate service to our customers, which may put us at a
competitive disadvantage. Our attempts to provide prompt delivery may necessitate that in China we produce and keep
on hand substantially more inventory of finished products than would otherwise be needed. Inventory fluctuations can
materially and adversely affect our margins, cash flow and profits.

We are subject to U.S. and international tax laws that could affect our financial results.

We generally conduct international operations through our wholly-owned subsidiaries. Our income tax liabilities in the
different countries where we operate depend in part on internal settlement prices and administrative charges among us
and our subsidiaries. These arrangements require us to make judgments with which tax authorities may disagree. Tax
authorities may impose additional tariffs, duties, taxes, penalties and interest on us. Transactions that we have arranged
in light of current tax rules could have material and adverse consequences if tax rules change, and changes in tax rules or
imposition of any new or increased tariffs, duties and taxes could materially and adversely affect our sales, profits and
financial condition.

As of December 31, 2015, we held $93.2 million outside the U.S. as a result of operations from our international
subsidiaries, and any repatriation of funds currently held in foreign jurisdictions to the U.S. may result in higher effective
tax rates for us. In addition, there have been proposals from Congress to change U.S. tax laws that would significantly
impact how U.S. multinational corporations like us are taxed on foreign earnings.

Recent changes in applicable law regarding the transfer of personally identifiable information by U.S. companies
doing business in the European Union could lead us to spend significant resources trying to comply with the newly
developed rules. We may not succeed in meeting such requirements, and we may face governmental actions and
suffer business losses.

We have in the past relied on adherence to the U.S. Department of Commerce’s Safe Harbor Policy Principles and
compliance with the Safe Harbor Frameworks as agreed to and set forth by the European Commission and the United
States, which established a means for legitimating the transfer of personally identifiable information by U.S. companies
doing business in the European Union (“EU”) to the U.S. As a result of an October 6, 2015 European Union Court of
Justice (“ECJ”) opinion, the Safe Harbor Framework no longer provides a lawful basis to transfer data from the EU to
the U.S. On February 2, 2016, the European Commission and the United States agreed on a new framework for transatlantic
data sharing; the Privacy Shield. The Privacy Shield aims to strengthen protections of European personal data and
monitoring and enforcement of such protections in the U.S., compared to that provided under the prior Safe Harbor
Frameworks.

In light of that ECJ opinion and the Privacy Shield, we may need to engage in additional compliance efforts when
transferring certain data from the EU. We may be unsuccessful in complying with the new EU data transfer requirements,
and as a result, we may be at risk of enforcement actions taken by an EU data protection authority until such point in
time that we ensure all data transfers to us from the EU are in compliance with applicable law. We may find it necessary
to establish systems to maintain EU-origin data in the European Economic Area, which may involve substantial expense
and distraction from other aspects of our business.

Capital Structure and Stock Risks

A stockholder controls approximately 15% of the outstanding shares of our common stock, which may reduce
other stockholders' ability to influence our affairs.

As of December 31, 2015, Sharon Simpson controlled, directly and indirectly, approximately 15% of the then outstanding
shares of our common stock. Ms. Simpson, therefore, has significant influence with respect to our corporate matters

requiring stockholder approval such as the election of our directors and proposals that come before the stockholders at
the annual meeting or other special meetings.

Further, if all or a substantial portion of her shares of our common stock is sold, it could depress the price of our common
stock.

Any issuance of preferred stock may dilute your investment and reduce funds available for dividends.

Our Board of Directors is authorized by our Certificate of Incorporation to determine the terms of one or more series of
preferred stock and to authorize the issuance of shares of any such series on such terms as our Board of Directors may
approve. Any such issuance could be used to impede an acquisition of our business that our Board of Directors does not
approve, further dilute the equity investments of holders of our common stock and reduce funds available for the payment
of dividends to holders of our common stock.

Future sales of our common stock could adversely affect our stock price.

Our Board of Directors has the authority to issue, from time to time, authorized and unissued shares of our common
stock. Our issuance of substantial amounts of new shares of our common stock could adversely affect the prevailing
market price for our common stock.

All of the outstanding shares of our common stock are freely tradable without restriction under the Securities Act of 1933,
as amended (the "Securities Act"), other than shares of our common stock held by our “affiliates,” as that term is defined
in Rule 144 under the Securities Act. There were 7,239,930 million shares held by our affiliates as of February 25, 2016.
In addition as of December 31, 2015, options to purchase 0.5 million shares of our common stock were outstanding and
exercisable and restricted stock units with respect to 0.5 million shares of our common stock were unvested.

If a substantial number of shares of our common stock are sold in the public market pursuant to Rule 144 by our affiliates
or issued upon the exercise of our outstanding options, the trading price of our common stock in the public market could
be adversely affected.

Delaware law, our stockholder rights plan and certain other aspects of our corporate governance contain anti-
takeover provisions that could deter takeover attempts that might otherwise be beneficial to our stockholders.

Provisions of Delaware law could make it more difficult for a third party to acquire us. Section 203 of the Delaware
General Corporation Law makes the acquisition of the Company and the removal of our incumbent officers and directors
more difficult for potential acquirers by prohibiting stockholders holding 15% or more of our outstanding voting stock
from acquiring us without the consent of our Board of Directors for at least three years from the date they first hold 15%
or more of the voting stock.

We also have the following protective measures, among others:

• Our Stockholder Rights Plan also has significant anti-takeover effects by causing substantial dilution to a person

or group that attempts to acquire us on terms not approved by our Board of Directors.

• Our tiered Board of Director structure, whereby only a portion of our Board of Directors is elected at each annual

meeting, also discourages take-over attempts that might otherwise be beneficial to our stockholders.
•
Stockholders cannot call special meetings of the stockholders and cannot take action by written consent.
• A change in the composition of the Board of Directors that is not approved by our existing Board of Directors

could trigger a default under our existing credit facilities.

Employee Risks

We depend on key management and technical personnel, the loss of whom could harm our business.

We depend on our key management and technical personnel. The loss of one or more key employees could materially
and adversely affect us.

Our success also depends on our ability to attract and retain highly qualified technical, sales and marketing and management
personnel necessary for the maintenance and expansion of our activities. We face strong competition for such personnel

and may not be able to attract or retain such personnel. In addition, when we experience periods with little or no profits,
a decrease in compensation based on our profits may make it difficult to attract and retain highly qualified personnel.

Any work stoppage or interruption by employees could materially and adversely affect our business and financial
condition.

A significant number of our employees are represented by labor unions and covered by collective bargaining agreements
that will expire in 2017, 2018 and 2019. Although we believe that our relations with our employees are satisfactory, no
assurance can be given that we will be able to successfully extend or renegotiate our collective bargaining agreements
as they expire from time to time. If we fail to extend or renegotiate our collective bargaining agreements, if disputes with
our unions arise, or if our unionized workers engage in a strike or other work stoppage or interruption, we could experience
a significant disruption of, or inefficiencies in, our operations or incur higher labor costs, which could have a material
adverse effect on our business, results of operations, financial position and liquidity.

Other Risks

Natural disasters could decrease our manufacturing capacity.

Some of our current manufacturing facilities are located in geographic regions that have experienced major natural
disasters, such as earthquakes, floods and hurricanes. Our disaster recovery plan may not be adequate or effective. We
do not carry earthquake insurance. Other insurance that we carry is limited in the risks covered and the amount of coverage.
Our insurance would not be adequate to cover all of our resulting costs, business interruption and lost profits when a
major natural disaster occurs. A natural disaster rendering one or more of our manufacturing facilities totally or partially
unusable, whether or not covered by insurance, would materially and adversely affect our business and financial condition.

Climate change could materially and adversely affect our business.

We cannot predict the effects that climate change may have on our business. They might, for example:

•
•
•
•
•
•
•
•
•

depress or reverse economic development,
reduce the demand for construction,
increase the cost and reduce the availability of fresh water,
destroy forests, increasing the cost and reducing the availability of wood products used in construction,
increase the cost and reduce the availability of raw materials and energy,
increase the cost of capital,
increase the cost and reduce the availability of insurance covering damage from natural disasters,
lead to claims regarding the content or adequacy of our public disclosures, and
lead to new laws and regulations that increase our expenses and reduce our sales.

Any of these consequences, and other consequences of climate change that we do not foresee, could materially and
adversely affect our sales, profits and financial condition.

We may have exposure to greater than anticipated tax liabilities.

We provide guidance on our anticipated tax rates. Failure to meet these anticipated rates could cause us to miss analyst
forecasts and could result in material declines in our stock price. Our future income taxes could be adversely affected
by earnings being lower than anticipated in jurisdictions that have lower statutory tax rates and higher than anticipated
in jurisdictions that have higher statutory tax rates, by changes in the valuation of our deferred tax assets and liabilities,
as a result of changes in foreign tax exchanges, or changes in tax laws, regulations, or accounting principles, as well as
certain discrete items. The determination of our worldwide provision for income taxes and other tax liabilities requires
significant judgment, and there are many transactions and calculations where the ultimate tax determination is uncertain.
Although we believe our estimates are reasonable, the ultimate tax outcome may differ from the amounts recorded in our
financial statements and may materially affect our financial results in the period or periods for which such determination
is made.

Contracts that we file as exhibits to our public reports contain recitals, representations and warranties that may
not be factually correct.

The parties to any agreement or other instrument that we file as an exhibit to this or any other report did not necessarily
intend that any recital, representation, warranty or other statement of purported fact in the instrument establish or confirm
any fact, even if it is worded as such. Often such statements are used to allocate contractual risk between the parties, and
the statements often are subject to standards of materiality that differ from the standards applicable to our reports. In
addition, such statements may have been qualified by other materials that we have not filed with (or incorporated by
reference into) this or any other report or document. Such exhibits should be read in the context of our other disclosures
in our reports and it should not be assumed that any statement, representation or warranty of any party is necessarily
factually accurate.

Impairment charges on goodwill or other intangible assets adversely affect our financial position and results of
operations.

We are required to perform impairment tests on our goodwill, indefinite-lived intangible assets and definite-lived intangible
assets annually or at any time when events occur that could affect the value of such assets. To determine whether a
goodwill impairment has occurred, we compare fair value of each of our reporting units with its carrying value. In the
past, these tests have lead us to incur significant impairment charges. Significant and unanticipated changes in
circumstances, such as significant adverse changes in business climate, adverse actions by regulatory authorities,
unanticipated competition, loss of key customers or changes in technology or markets, can require a charge for impairment
that can materially and adversely affect our reported net income and our stockholders’ equity.

Failure of our accounting systems could harm our business and financial results.

We have implemented a commercially available Microsoft third-party accounting software system for use in our operations
in the United States, Europe and Asia. Any errors or defects in, or unavailability of, third-party software or our
implementation of the systems, could result in errors in our financial statements, which could materially and adversely
affect our business. If we continue to use our other internally developed accounting systems and they are not able to
accommodate our future business needs, or if we find that they or any new systems we may implement contain errors or
defects, our business and financial condition could be materially and adversely affected.

Changes in accounting standards could materially and adversely affect our financial results.

The accounting rules applicable to public companies are subject to frequent revision. Future changes in accounting
standards, guidance and interpretations could require us to change the way we measure revenue, expense or balance sheet
amounts, which could result in material and adverse change to our reported results of operations or financial condition.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

The Company owns its home office in Pleasanton, California, and its principal United States manufacturing facilities in Stockton
and San Bernardino County, California, McKinney, Texas, and Columbus, Ohio. The principal manufacturing facilities located
outside the United States, the majority of which are owned, are in Canada, France, Denmark, Germany, Poland, Switzerland,
Portugal and China. The Company also owns and leases smaller manufacturing facilities, warehouses, research and development
facilities and sales offices in the United States, Europe, Asia, Australia, New Zealand, South Africa and Chile. As of February 26,
2016, the Company’s owned and leased facilities were as follows:

The Company’s properties are constructed primarily of steel, brick or concrete and, in management’s opinion, are maintained in
good operating condition. The Company’s manufacturing facilities are equipped with specialized equipment and use extensive
automation. The Company considers its existing and planned facilities to be adequate for its operations as currently conducted
and as planned through 2016. The Company’s leased facilities typically have renewal options and have expiration dates through
2022. The Company believes it will be able to extend leases on its various facilities as necessary, as they expire. The manufacturing
facilities currently are being operated with one full shift. The Company anticipates that it may require additional facilities to
accommodate possible future growth.

In December 2015, the Company purchased for $12.6 million a manufacturing facility in West Chicago for the purposes of
combining the operations of two leased chemical facilities into one owned facility. The Company estimates 2016 costs to complete
improvements to operate out of the new facility will be $7.0 million to $10.0 million.

The Company retained its real estate in Vacaville, California. On completion of the sale of the Simpson Dura-Vent assets to M&G
in 2010, the Company leased that facility to M&G for approximately $0.9 million per year for ten years. These properties are
classified under the “Administrative & All other” segment.

Item 3. Legal Proceedings.

From time to time, the Company is involved in various legal proceedings and other matters arising in the normal course of business.
As of February 26, 2016, other than ordinary routine litigation incidental to the Company’s business, the Company is not a party
to any legal proceedings, which the Company expects individually or in the aggregate to have a material adverse effect on the
Company’s financial condition, cash flows or results of operations. Nonetheless, the resolution of any claim or litigation is subject
to inherent uncertainty and could have a material adverse effect on the Company’s financial condition, cash flows or results of
operations.

Other

Corrosion, hydrogen enbrittlement, cracking, material hardness, wood pressure-treating chemicals, misinstallations, misuse, design
and assembly flaws, manufacturing defects, labeling defects, product formula defects, inaccurate chemical mixes, adulteration,
environmental conditions, or other factors can contribute to failure of fasteners, connectors, anchors, adhesives, specialty chemicals,
such as fiber reinforced polymers, and tool products. In addition, inaccuracies may occur in product information, descriptions
and instructions found in catalogs, packaging, data sheets, and the Company’s website. The Company has not incurred any material
liability resulting from any such failures and/or inaccuracies.

Item 4. Mine Safety Disclosures.

Not applicable.

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

The following is a discussion and analysis of the financial condition and results of operations, unless stated otherwise, for the
Company for the years ended December 31, 2015, 2014 and 2013, and of certain factors that may affect the Company’s prospective
financial condition and results of operations. The following discussion and analysis contain forward-looking statements as
discussed in the “Note About Forward-Looking Statements” at the beginning of this Annual Report on Form 10-K and should be
read in conjunction with the Consolidated Financial Statements and related Notes included in Part II, Item 8, "Financial Statements
and Supplementary Data" of this Annual Report on Form 10-K. In addition to our historical consolidated financial information,
the following discussion contains forward-looking statements that reflect our plans, estimates, and beliefs. Our actual results could
differ materially from those plans, estimates, and beliefs. Factors that could cause or contribute to these differences include those
discussed below and elsewhere in this Annual Report on Form 10-K, particularly "Item 1A, Risk Factors."

Overview

The Company's strategy is to grow its building material product offerings and geographic sales footprint so it is not so heavily
dependent on North America housing starts. It is focused on expanding sales in wood products by introducing new products into
markets it currently operates in or entering new geographic markets, such as in Europe. New wood products, such as fasteners,
may be internally developed or acquired. The Company is also focused on growing its concrete products business in all segments
it operates in and will also search for new acquisition opportunities, such as concrete repair. The Company's strategy is to grow
into new markets and products while leveraging its strengths in engineering, sales and distribution, and strong brand name.

The Company designs, manufactures and sells building construction products that are of high quality and performance, easy to
use and cost-effective for customers. It operates in three business segments determined by geographic region; North America,
Europe and Asia/Pacific.

• The North America segment sells both wood and concrete construction products and has been highly dependent on housing
starts. The Company has made efforts to be less dependent on new housing construction by expanding its line of concrete
construction products. North America concrete construction product sales increased 19% in 2015 from 2013, partly due
to improved economic conditions.

• The Europe segment also sells both wood and concrete construction products and until recently relied primarily on wood
construction products. Europe concrete construction product sales increased 9% in 2015 from 2013, primarily due to
improved economic conditions and expanded sales activities into new countries, partly offset by the negative effects of
foreign currency translation.

• The Asia/Pacific segment also sells both wood and concrete construction products. The Company has closed its sales
offices located in China, Thailand and Dubai, as well as reduced its selling activities in Hong Kong, due to continued
losses in the regions. As a result, concrete construction product sales decreased over 52% in 2015 from 2013 and wood
construction product sales decreased 6% in 2015 from 2013. The Company believes that the Asia/Pacific segment is not
significant to the Company's overall performance.

The Company continues to invest in its strategic initiatives, such as expanding its offering of concrete construction products,
including specialty chemicals, wood construction products, particularly its truss plate and fasteners, and software offerings. In
support of these initiatives, the Company expects to commit resources to improve and increase manufacturing capabilities and is
prepared to invest resources to acquire products or businesses that meets the Company's goals.

The Company generally manufactures products and incurs costs in the areas where sales occur. Therefore, for each of the Company’s
foreign operations the local currency is the functional currency and each foreign operation transacts primarily in its functional
currency. The Company does not currently plan to enter into foreign currency contracts to hedge its exposure to foreign exchange
rates.

The Administrative & All Other segment primarily includes expenses such as self-insured workers compensation claims costs for
employees of the Company’s venting business, which was sold in 2010, stock-based compensation for certain members of
management, interest expense, foreign exchange gains or losses and income tax expense, as well as income and expenses related
to real estate activities, such as rental income and depreciation expense on the Company’s facility in Vacaville, California, which
the Company has leased to a third party for a 10-year term expiring in August 2020.

2013 to 2015 Financial Highlights

From 2013 to 2015, net sales increased to $794.1 million from $705.3 million. The Company had net income of $67.9 million for
2015 compared to net income of $51.0 million for 2013. Diluted net income per common share was $1.38 for 2015 compared to
49

$1.05 for 2013. Income from operations increased to $109.0 million in 2015 from $81.5 million in 2013. The increased net sales
were primarily driven by improved economic conditions and increased building activity in 2015 compared to 2013.

Net sales

Net sales increased to $794.1 million in 2015 from $705.3 million in 2013, reflecting improved economic conditions in North
America.

•

Segment net sales:

North America — Net sales increased to $676.6 million in 2015 from $572.8 million in 2013 with above average
increases in the United States. Canada net sales decreased, primarily due to the effects of foreign currency translation.
The net sales increases in North America were mostly due to increases in unit sales volume in both concrete
construction and wood products from increased building activity, partly offset by a decrease in average sales prices.
Europe — Net sales decreased to $108.1 million in 2015 from $117.7 million in 2013, due to the effects of foreign
currency translation. The Company calculated that Europe's 2015 net sales were negatively affected by approximately
$16.2 million due to European currencies weakening against the United States dollar. In local currencies, Europe's
overall net sales increased in 2015 compared to 2013, primarily due to increases in unit sales volume, partly offset
by a slight decrease in average sales prices.
Asia/Pacific — Net sales decreased to $9.4 million in 2015 from $14.8 million in 2013, due to the closing of sales
offices in China, Thailand and Dubai, which accounted for approximately $5.8 million of the total decrease in net
sales in the region.

•

Sales channels and product groups:

Net sales to contractor distributors, lumber dealers and dealer distributors increased significantly in 2015 compared
to 2013 due to increased construction activity.
Wood construction product net sales, including connectors, truss plates, fastening systems, fasteners and shearwalls,
increased 13.0% to $674.3 million in 2015 from $596.8 million in 2013, primarily due to increased unit sales volumes
on improved economic conditions, partly offset by the negative effects of foreign currency translation.
Concrete construction product sales, including adhesives, chemicals, mechanical anchors, powder actuated tools and
reinforcing fiber materials, increased 10.3% to $119.5 million in 2015 from $108.3 million in 2013, primarily due
to increased unit sales volumes on improved economic conditions, partly offset by the negative effects of foreign
currency translation as well as the closure of sales offices located in China, Thailand and Dubai.

Gross profit

Gross profit margin increased to 45.2% in 2015 from 44.5% in 2013. Wood construction products represented 85% of total sales
in both 2015 and 2013. The overall 2015 gross profit margin as a percentage of sales was up due to increased profit margins on
the sale of wood construction products. The gross profit margin differential between wood construction products and concrete
construction products increased to 16% in 2015 from 13% in 2013.

Operating expenses

Operating expenses increased in dollar amounts, but decreased as a percentage of net sales, and were $249.9 million, or 31.5% of
net sales, in 2015, compared to $232.1 million, or 32.9% of net sales, in 2013. The increase in operating expenses was primarily
due to the support of new products lines, which included increased personnel costs, mostly related to the addition of staff, and
software development costs, as well as increased cash profit sharing expense related to increased operating profits, partly offset
by the effects of foreign currency translation.

• North America - Net sales increased 10.2% in 2015 compared to 2014, primarily due to increased unit sales volumes
in the United States on improved economic activity, partly offset by a slight decrease in average sales prices.
Canadian net sales decreased, mostly due to the effects of foreign currency translations, partly offset by an increase
in unit sales volumes. The Company calculated that Canada's 2015 net sales were negatively affected by
approximately $5.6 million due to the Canadian dollar weakening against the United States dollar. In Canadian
dollars, Canada's overall net sales increased slightly in 2015 compared to 2014.

• Europe - Net sales decreased 12.3% in 2015 compared to 2014, mostly due to the effects of foreign currency
translations. The Company calculated that Europe's 2015 net sales were negatively affected by approximately
$17.6 million due to European currencies weakening against the United States dollar. In local currencies, Europe's
overall net sales increased slightly in 2015 compared to 2014.

• Asia/Pacific - Net sales decreased 38.0% in 2015 compared to 2014, primarily due to the closing of sales offices
in China, Thailand and Dubai, which accounted for approximately $5.6 million of the total decreases in net sales
in the region. Foreign currency translations due to the weakening of the respective currencies against the United
States dollar negatively affected net sales by approximately $0.6 million.

• Consolidated net sales channels and product groups:

• Net sales to contractor distributors, dealer distributors, home centers and lumber dealers increased in 2015 compared

to 2014, primarily due to increased home construction activity.

• Wood construction product net sales, including connectors, truss plates, fastening systems, fasteners and shearwalls,

represented 85% of our total net sales in both 2015 and 2014.

• Concrete construction product sales, including adhesives, chemicals, mechanical anchors, powder actuated tools

and reinforcing fiber materials, represented 15% of our total net sales in both 2015 and 2014.

Gross profit increased to $358.9 million in 2015 from $342.0 million in 2014. Gross profit as a percentage of net sales decreased
to 45.2% in 2015 from 45.5% in 2014, partly due to a non-reoccurring $2.5 million correction to workers' compensation expense
in the North America segment that increased the Company's 2014 gross profit by 0.3% of net sales and increases in material costs.
Based on current information and subject to future events and circumstances, the Company estimates that its 2016 gross profit
margin will be between 44.5% and 46.0%.

• North America - Gross profit margin decreased to 46.9% in 2015 from 47.4% in 2014, primarily as a result of increases in
material costs, as a percentage of net sales, partly offset by slight decreases in factory overhead cost and shipping cost, each
as a percentage of sales. Factory overhead cost, as a percentage of net sales, in 2014 was affected by a non-reoccurring $2.5
million correction to workers' compensation expense that increased the 2014 gross profit margin by 0.4%. Factory overhead,
as a percentage of net sales, in 2015 was reduced by a non-reoccurring settlement of a union-based defined-benefit pension
withdrawal liability that increased 2015 gross profit margin by 0.1% as compared to 2014 when an atypical non-recurring
$3.3 million pension charge resulted from the Company's withdrawal from a multiemployer union-based defined-benefit
pension plan.

•

• Europe - Gross profit margin increased to 38.4% in 2015 from 38.1% in 2014, as a result of decreases in material costs,
factory overhead (on increased production volumes) and warehouse costs, each as a percentage of sales, partly offset by
increases in the costs of labor and shipping, each also as a percentage of sales.
Product mix - The gross profit margin differential between wood construction products and concrete construction products,
which have lower gross profit margins, was 16% and 12% in 2015 and 2014, respectively. The increased gross profit margin
differential between the two product groups, coupled with increased concrete construction product sales in 2015, also
negatively affected the Company's overall gross profit margin. The lower gross profit margins on concrete construction
products negatively affected gross margins in North America, with concrete construction products representing 13% of
North America net sales in 2015 and 2014, and in Europe, with concrete construction products at 23% and 20% of Europe
net sales in 2015 and 2014, respectively.
Steel prices - Given current conditions, including low demand, labor union contract negotiations, anti-dumping and
countervailing duty trade cases filed by United States steel producers, the Company currently expects that the high degree
of uncertainty regarding steel prices will continue.

•

Research and development and engineering expense

Research and development and engineering expense increased 18.4% to $46.2 million in 2015 from $39.0 million in 2014, primarily
due to $5.9 million in write-offs of software development projects, as well as increases of $2.0 million in personnel costs related
to the addition of staff and pay rate increases instituted in January 2015 and $0.6 million in cash profit sharing expense on increased
operating profits, partly offset by a decrease of $0.7 million in stock-based compensation costs, most of which occurred in the
North America segment.

Selling expense

Selling expense decreased 1.5% to $90.7 million in 2015 from $92.0 million in 2014, primarily due to decreases of $0.9 million
in professional fees, $0.7 million in stock-based compensation and $0.6 million in advertising costs, partly offset by increases of
$0.5 million in cash profit sharing and commission expense, $0.3 million in agent commission expense and $0.2 million in personnel
costs related to the addition of staff and pay rate increases instituted in January 2015.

• North America - Selling expense increased $0.9 million, primarily due to increases of $1.5 million in personnel costs and
$1.1 million in cash profit sharing and commission expense, partly offset by decreases of $0.7 million in stock-based
compensation, $0.7 million in professional fees and $0.4 million in advertising costs.

• Europe - Selling expense decreased by $0.9 million, primarily due to decreases of $1.1 million in personnel costs and $0.2
million in professional fees, partly offset by a $0.4 million increase in agent commission expense, primarily attributable to
differences in exchange rates used for translating local currencies into United States dollars.

• Asia/Pacific - Selling expense decreased $1.3 million, primarily due to decreases of $0.6 million in personnel costs and
$0.5 million in cash profit sharing and sales commissions, both related to closing three sales offices and downsizing one
sales office.

General and administrative expense

General and administrative expense increased 1.7% to $113.4 million in 2015 from $111.5 million in 2014, primarily due to
increases of $2.2 million in personnel costs related to the addition of staff and pay rate increases instituted in January 2015, $0.6
million in stock-based compensation expense, $0.4 million in bad debt expense and $0.1 million in cash profit sharing, partly
offset by a decrease of $1.1 million in amortization expense.

• North America - General and administrative expense increased $2.8 million, primarily due to increases of $2.4 million in
personnel costs, $0.3 million in cash profit sharing expense, $0.3 million in stock-based compensation costs and $0.2 million
in bad debt expense, partly offset by a decrease of $0.7 million in amortization expense.

• Europe - General and administrative expense decreased by $2.1 million, primarily due to decreases of $1.1 million in
personnel costs, $0.5 million in cash profit sharing and $0.3 million in intangible amortization expense, primarily attributable
to differences in exchange rates used for translating local currencies into United States dollars.

• Asia/Pacific - General and administrative expenses increased by $0.3 million, primarily due to increases of $0.4 million in

personnel costs.

• Administrative and Other - General and administrative expense increased by $0.9 million, primarily due to increases of
$0.4 million in personnel cost, $0.3 million in stock-based compensation expense and $0.2 million in cash profit sharing.

Income taxes

The effective income tax rate in 2015 was 37.5% as compared to 36.0% in 2014. The 2015 effective income tax rate was higher
primarily due to the 2014 release of an uncertain tax position as well as a solar tax credit for installing solar panels at one of the
Company's facilities, which were non-reoccurring. Based on current information and subject to future events and circumstances,
the Company estimates that its 2016 effective tax rate will be between 37% and 39%.

• North America - Net sales increased 7.2% in 2014 compared to 2013, primarily due to increased unit sales

volumes, while average prices for the year were down 0.6%.

• Europe - Net sales increased 4.6% in 2014 compared to 2013, mostly due to increased unit sales volumes and
the effects of foreign currency translations, partly offset by slightly lower average selling prices. However, sales
growth trended lower in the last two quarters of 2014, consistent with declining economic activity in the region,
and European currencies have weakened against the United States dollar.

• Consolidated net sales channels and product groups:

• Net sales to lumber dealers, contractor distributors, dealer distributors and home centers increased in 2014

compared to 2013, due to increased building activity.

• Wood construction product net sales represented 85% of our total net sales in both 2014 and 2013.
• Concrete construction product net sales represented 15% of our total net sales in both 2014 and 2013.

Gross profit increased to $342.0 million in 2014 from $313.5 million in 2013. Gross profit as a percentage of net sales increased
to 45.5% in 2014 from 44.5% in 2013.

• North America - Gross profit margin increased to 47.4% in 2014 from 46.7% in 2013, as a result of decreases as a
percentage of sales in material, labor and warehousing costs. In 2014, the gross profit margin was also affected by an
atypical non-recurring $3.3 million pension charge that resulted from the Company's withdrawal from a multi-employer
union-based defined-benefit pension plan, partly offset by an atypical non-recurring $2.5 million correction to workers'
compensation expense in states where the Company is not self-insured.

•

• Europe - Gross profit margin increased to 38.1% in 2014 from 37.0% in 2013, as a result of decreases as a percentage
of sales in factory overhead (caused by increased unit sales volumes) and material costs, partly offset by increases in
shipping and warehouse and labor costs.
Product mix - The gross profit margin differential between wood construction products and concrete construction products,
which have lower gross profit margins, was 12% and 13% in 2014 and 2013, respectively. The lower gross profit margins
on concrete construction products negatively affected gross margins in North America, with concrete construction products
representing 13% of North America net sales in both 2014 and 2013, respectively, and in Europe, with concrete construction
products representing 20% and 19% of Europe net sales in 2014 and 2013, respectively.
Steel prices - The market price for steel decreased in December 2014.

Research and development and engineering expense

Research and development and engineering expense increased 5.9% to $39.0 million in 2014 from $36.8 million in 2013, primarily
due to an increase of $2.1 million in personnel costs related to the addition of staff in support of product and software development
and pay rate increases instituted in January 2014, and an increase of $0.9 million in cash profit sharing, partly offset by a decrease
of $1.0 million in expensed software development costs.

• North America - Research and development and engineering expense increased $1.9 million, primarily due to increases
of $2.1 million in personnel costs and $0.8 million in cash profit sharing, partly offset by a decrease in software development
costs of $1.1 million.

Selling expense

Selling expense increased 8.1% to $92.0 million in 2014 from $85.1 million in 2013, primarily due to increases of $2.9 million
in personnel costs, $2.2 million in professional fees, $1.0 million in cash profit sharing and commissions and $0.7 million in
advertising and promotional costs.

• North America - Selling expense increased $6.5 million, primarily due to an increase of $2.5 million in personnel costs
related to the addition of staff in support of product marketing initiatives and pay rate increases instituted in January
2014, and increases of $2.0 million in professional fees, $1.1 million in advertising and promotional costs and $0.7 million
in cash profit sharing and commissions.

• Europe - Selling expense increased $0.3 million, primarily due to increases of $0.4 million in personnel costs and $0.2
million in cash profit sharing and commissions, partly offset by a decrease of $0.3 million in advertising and promotional
costs.

General and administrative expense

General and administrative expense increased 3.2% to $111.5 million in 2014 from $108.1 million in 2013, primarily due to
increases of $2.5 million in cash profit sharing, $1.6 million in personnel costs, $0.7 million in unrealized foreign currency losses,
$0.4 million in depreciation expense and $0.2 million in facility maintenance expense, partly offset by a decrease in impairment
charges of $1.0 million related to an impairment of fixed assets in 2013, a decrease of $0.6 million in professional fees and a $0.3
million decrease in stock-based compensation, as well as a $0.5 million gain resulting from a reduction in a contingent liability
related to the Bierbach acquisition (compared to no gain recorded in 2013). See "Note 2 — Acquisitions" to the Company's
Consolidated Financial Statement.

• North America - General and administrative expense increased $4.3 million, primarily due to increases of $1.7 million
in cash profit sharing, $1.2 million in personnel costs related to the addition of administrative and information technology
staff and pay rate increases instituted in January 2014, $0.7 million in depreciation expense, $0.4 million in facility
maintenance expense and $0.2 million in stock-based compensation.

• Europe - General and administrative expense decreased by $0.9 million, primarily due to a $1.0 million impairment
charge related to an impairment of fixed assets in 2013, decreases of $0.8 million in professional fees, $0.5 million in
stock-based compensation, $0.2 million in depreciation expense and $0.2 million in facility maintenance expense as well
as a $0.5 million gain resulting from a reduction of a contingent liability related to the Bierbach acquisition, partly offset
by increases of $1.4 million in unrealized foreign currency losses, $0.5 million in cash profit sharing and $0.3 million in
personnel costs.

Impairment of goodwill

The impairment charge of $0.5 million taken in 2014 was associated with Bierbach goodwill acquired in Germany in November
2013, and as a result, the goodwill of the Germany reporting unit was fully impaired. The impairment resulted from a reduction
in expected future sales from former Bierbach customers. The Company’s 2014 annual goodwill impairment analysis did not result
in additional impairment of goodwill. See “Critical Accounting Policies and Estimates — Goodwill Impairment Testing."

Disposal of assets

The Company did not dispose of any material assets during 2014 compared to 2013 when the Company realized a $2.8 million
net loss on the liquidation of its Irish subsidiary, partly offset by a $1.4 million gain on the sale of its CarbonWrap product line.
See "Plant Closure" and "Sale of Product Line" under "Note 1 - Operations and Summary of Significant Accounting Policies" to
the Company's Consolidated Financial Statement.

Income taxes

The effective income tax rate in 2014 was 36.0%, a decrease compared to 37.5% in 2013. The decrease in the effective income
tax rate was primarily due to increased manufacturing deductions for certain types of expenditures, a solar tax credit for installing
solar panels at one of the Company's facilities, and reduced operating losses in 2014 in the Europe and Asia/Pacific segments for
which no tax benefit was recorded.

Critical Accounting Policies and Estimates

The critical accounting policies described below affect the Company’s more significant judgments and estimates used in the
preparation of the Consolidated Financial Statements. If the Company’s business conditions change or if it uses different
assumptions or estimates in the application of these and other accounting policies, the Company’s future results of operations
could be adversely affected.

Inventory Valuation

Inventories are stated at the lower of cost or net realizable value (market). Cost includes all costs incurred in bringing each product
to its present location and condition, as follows:

• Raw materials and purchased finished goods — principally valued at cost determined on a weighted average basis:

•

and
In-process products and finished goods — cost of direct materials and labor plus attributable overhead based on a
normal level of activity.

The Company applies net realizable value and obsolescence to the gross value of inventory. The Company estimates net realizable
value based on estimated selling price less further costs to completion and disposal. The Company impairs slow-moving products
by comparing inventories on hand to projected demand. If on-hand supply of a product exceeds projected demand or if the Company
believes the product is no longer marketable, the product is considered obsolete inventory. The Company revalues obsolete inventory
to its net realizable value. The Company has consistently applied this methodology. The Company believes that this approach is
prudent and makes suitable impairments for slow-moving and obsolete inventory. When impairments are established, a new cost
basis of the inventory is created. Unexpected change in market demand, building codes or buyer preferences could reduce the rate
of inventory turnover and require the Company to recognize more obsolete inventory.

Revenue Recognition

The Company recognizes revenue when the earnings process is complete, net of applicable provision for discounts, returns and
incentives, whether actual or estimated, based on the Company’s experience. This generally occurs when products are shipped to
the customer in accordance with the sales agreement or purchase order, ownership and risk of loss pass to the customer, collectability
is reasonably assured and pricing is fixed or determinable. The Company’s general shipping terms are F.O.B. shipping point, where
title is transferred and revenue is recognized when the products are shipped to customers. When the Company sells F.O.B. destination
point, title is transferred and the Company recognizes revenue on delivery or customer acceptance, depending on terms of the
sales agreement. Service sales, representing after-market repair and maintenance, engineering activities, software license sales
and service and lease income, though significantly less than 1% of net sales and not material to the Consolidated Financial
Statements, are recognized as the services are completed or the software products and services are delivered. If actual costs of
sales returns, incentives and discounts were to significantly exceed the recorded estimated allowance, the Company’s sales would
be adversely affected.

Business Combinations

The Company recognizes separately from goodwill the assets acquired and the liabilities assumed at their acquisition date fair
values. Goodwill as of the acquisition date is measured as the excess of consideration transferred and the net of the acquisition
date fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions as
a part of the purchase price allocation process to value assets acquired and liabilities assumed at the acquisition date, the Company’s
estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one
year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed, with the
corresponding offset to goodwill. On the conclusion of the measurement period or final determination of the values of assets
acquired or liabilities assumed, whichever comes first, the Company records subsequent adjustments, if any, to its consolidated
statements of operations. None of the subsequent adjustments for the years ended 2013, 2014 and 2015 were material.

Accounting for business combinations requires the Company’s management to make significant estimates and assumptions,
especially at the acquisition date with respect to intangible assets. Although the Company believes that the assumptions and
estimates it has made in the past have been reasonable and appropriate, they are based in part on historical experience and information
obtained from the management of the acquired companies and are inherently uncertain.

Examples of critical estimates in valuing certain of the intangible assets that the Company has acquired include:

Future expected cash flows from customer relationships and acquired unpatented technologies and patents;

•
• The acquired company’s brand and competitive position and assumptions about the period of time the acquired brand

will continue to be used in the combined company’s product portfolio; and

• Discount rates.

Unanticipated events and circumstances may affect the accuracy or validity of such assumptions, estimates or actual results.

For a given acquisition, the Company may identify pre-acquisition contingencies as of the acquisition date and may extend its
review and evaluation of these pre-acquisition contingencies throughout the measurement period (up to one year from the acquisition
date) to obtain sufficient information to assess whether the Company includes these contingencies as a part of the purchase price
allocation and, if so, to determine their estimated amounts.

If the Company determines that a pre-acquisition contingency (that is not income-tax related) is probable and estimable as of the
acquisition date, the Company records its best estimate for such a contingency as a part of the preliminary purchase price allocation.
The Company often continues to gather information and evaluate its pre-acquisition contingencies throughout the measurement
period. If the Company changes the amounts recorded or identifies additional pre-acquisition contingencies during the measurement
period, such amounts are included in the purchase price allocation during the measurement period and, subsequently, in the
Company’s results of operations.

In addition, the Company estimates uncertain tax positions and income tax related valuation allowances assumed in connection
with a business combination initially as of the acquisition date. The Company reevaluates these items quarterly with any adjustments
to its preliminary estimates being recorded to goodwill if the Company is within the measurement period. The Company continues
to collect information to determine estimated values. Subsequent to the measurement period or the Company’s final determination
of the uncertain tax positions estimated value or tax-related valuation allowances, whichever comes first, changes to these uncertain
tax positions and tax-related valuation allowances will affect the Company’s provision for income taxes in its consolidated statement
of operations and could have a material effect on the Company’s results of operations and financial position.

Goodwill Impairment Testing

The Company tests goodwill for impairment at the reporting unit level on an annual basis (in the fourth quarter for the Company).
The Company also reviews goodwill for impairment whenever events or changes in circumstances indicate the carrying value of
an asset may not be recoverable. These events or circumstances could include a significant change in the business climate, legal
factors, operating performance indicators, competition, or disposition or relocation of a significant portion of a reporting unit.

The reporting unit level is generally one level below the operating segment, which is at the country level, except for the United
States, Australia and S&P Clever reporting units.

The Company determined that the United States reporting unit includes four components: Northwest United States, Southwest
United States, Northeast United States and Southeast United States (collectively, the “U.S. Components”). The Company aggregates
the U.S. Components into a single reporting unit because management concluded that they are economically similar and that the
goodwill is recoverable from the U.S. Components working in concert. The U.S. Components are economically similar because
of a number of factors, including selling similar products to shared customers and sharing assets and services such as intellectual
property, manufacturing assets for certain products, research and development projects, manufacturing processes, management of
inventory excesses and shortages and administrative services. These activities are managed centrally at the U.S. Components level
and costs are allocated among the four U.S. Components.

The Company determined that the Australia reporting unit includes three components: Australia, New Zealand and South Africa
(collectively, the “AU Components”). The Company aggregates the AU Components into a single reporting unit because
management concluded that they are economically similar and that the goodwill is recoverable from the AU Components working
in concert. The AU Components are economically similar because of a number of factors, including that New Zealand and South
Africa operate as extensions of their Australian parent company selling similar products and sharing assets and services such as
intellectual property, manufacturing assets for certain products, management of inventory excesses and shortages and administrative
services. These activities are managed centrally at the AU Components level and costs are allocated among the AU Components.

The Company determined that the S&P Clever reporting unit includes eight components: S&P Switzerland, S&P Poland, S&P
Austria, S&P The Netherlands, S&P Portugal, S&P Germany, S&P France and S&P Nordic (collectively, the "S&P Components”).
The Company aggregates the S&P Components into a single reporting unit because management concluded that they are
economically similar and that the goodwill is recoverable from the S&P Components working in concert. The S&P Components
are economically similar because of a number of factors, including sharing assets and services such as intellectual property,
manufacturing assets for certain products, research and development projects, manufacturing processes, management of inventory
excesses and shortages and administrative services. These activities are managed centrally at the S&P Components level and costs
are allocated among the S&P Components.

For certain reporting units, the Company may first assess qualitative factors related to the goodwill of the reporting unit to determine
whether it is necessary to perform a two-step impairment test. If the Company judges that it is more likely than not that the fair
value of the reporting unit is greater than the carrying amount of the reporting unit, including goodwill, no further testing is required.
If the Company judges that it is more likely than not that the fair value of the reporting unit is less than the carrying amount of the
reporting unit, including goodwill, management will perform a two-step impairment test on goodwill. In the first step of the
Company's annual goodwill impairment test ("Step 1"), the Company compares the fair value of the reporting unit to its carrying
value. The fair value calculation uses both the income approach (discounted cash flow method) and the market approach, equally
weighted. If the Company judges that the carrying value of the net assets assigned to the reporting unit, including goodwill, exceeds
59

the fair value of the reporting unit, a second step of the impairment test must be performed to determine the implied fair value of
the reporting unit’s goodwill. If the Company judges that the carrying value of a reporting unit’s goodwill exceeds its implied fair
value, the Company would record an impairment charge equal to the difference between the implied fair value of the goodwill
and the carrying value.

Determining the fair value of a reporting unit or an indefinite-lived purchased intangible asset is a judgment involving significant
estimates and assumptions. These estimates and assumptions include revenue growth rates, operating margins and working capital
requirements used to calculate projected future cash flows, risk-adjusted discount rates, selected multiples, control premiums and
future economic and market conditions (Level 3 fair value inputs). The Company bases its fair value estimates on assumptions
that it believes to be reasonable, but that are unpredictable and inherently uncertain. Actual future results may differ from those
estimates.

Assumptions about a reporting unit’s operating performance in the first year of the discounted cash flow model used to determine
whether or not the goodwill related to that reporting unit is impaired are derived from the Company’s budget. The fair value model
considers such factors as macro-economic conditions, revenue and expense forecasts, product line changes, material, labor and
overhead costs, tax rates, working capital levels and competitive environment. Future estimates, however derived, are inherently
uncertain but the Company believes that this is the most appropriate source on which to base its fair value calculations.

The Company uses these parameters only to provide a basis for the determination of whether or not the goodwill related to a
reporting unit is impaired. No inference whatsoever should be drawn from these parameters about the Company’s future financial
performance and they should not be taken as projections or guidance of any kind.

The 2015, 2014 and 2013 annual testing of goodwill for impairment did not result in impairment charges. The impairment charge
taken in the third quarter of 2014 was associated with assets in the Germany reporting unit acquired from Bierbach in 2013. The
factors that led to the third quarter impairment were a failure to retain Bierbach's historical customers and increased competition,
which led to the reduction in the contingent consideration liability, related to the Bierbach acquisition and resulted in management
performing an impairment test to evaluate the recoverability of the Germany reporting unit's goodwill. The test resulted in the
impairment of all of the reporting unit’s goodwill in the amount of $0.5 million. In connection with the impairment of the goodwill,
the Company also reviewed associated long-lived assets in Germany, such as property and equipment, and intangible assets, for
recoverability by comparing the projected undiscounted net cash flows associated with those assets to their carrying values. No
impairment of long-lived assets was required as a result of that review during the third quarter of 2014.

The Denmark reporting unit passed Step 1 of the annual 2015 impairment test by a 9% margin indicating an estimated fair value
greater than its net book value and was the only reporting unit with a fair value greater than net book value margin of less than
10%. The Denmark reporting unit is sensitive to management’s plans for retaining or replacing lost sales and operating margins.
The Denmark reporting unit’s failure to meet management’s objectives could result in future impairment of some or all of the
Denmark reporting unit’s goodwill, which was $6.4 million at December 31, 2015.

Key assumptions used in Step 1 of the Company's annual goodwill impairment test included compound annual growth rates
(“CAGR”) and average annual pre-tax operating margins during the forecast period, and discount rates. A sensitivity assessment
for the key assumptions included in the 2015 goodwill impairment test on the Denmark reporting unit is as follows:

• A 480 basis point hypothetical percentage increase in the discount rate, holding all other assumptions constant, would
not have decreased the fair value of the reporting unit below its carrying value, and thus it would not result in the reporting
unit failing Step 1 of the goodwill impairment test;

• A 105 basis point hypothetical percentage decrease in the CAGR, holding all other assumptions constant, would not have

decreased the fair value of the reporting unit below its carrying value and

• A 40% hypothetical decrease in average annual pre-tax operating profit, holding all other assumptions constant, would

not have decreased the fair value of the reporting unit below its carrying value.

Effect of New Accounting Standards

Recently Adopted Accounting Standards

In September 2015, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update No. 2015-16,
(Topic 805), Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2015-16”). ASU 2015-16 amendments
eliminate the requirement to restate prior period financial statements for measurement period adjustments made to provisional
amounts recognized in a business combination. The new guidance requires that the cumulative impact of measurement period
adjustments (including the impact on prior periods) be recognized in the reporting period in which the adjustments are determined.

The amendments require preparers to present cumulative adjustments separately within the respective financial line items affected
or disclose in the notes the amount recorded in current-period earnings. The new guidance does not change what constitutes a
measurement period adjustment. The new standard should be applied prospectively to measurement period adjustments that occur
after the effective date. The new standard is effective for interim and annual periods beginning after December 15, 2015, with
early adoption permitted. The Company early adopted this guidance effective December 15, 2015, and the adoption had no material
effect on its consolidated financial statements and footnote disclosures.

In April 2015, the FASB issued Accounting Standards Update No. 2015-05 (Subtopic 340-40), Customer’s Accounting for Fees
Paid in a Cloud Computing Arrangement (“ASU 2015-05"). The guidance in this Subtopic applies only to internal-use software
that a customer obtains access to in a hosted arrangement. The amendments provide guidance to customers about whether a cloud
computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer
should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a
cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service
contract. With an election to adopt prospectively or retrospectively, this ASU will be effective for annual periods beginning after
December 15, 2015. The Company early adopted ASU 2015-11 prospectively and the adoption had no material effect on its
consolidated financial statements and footnote disclosures.

In January 2015, the FASB issued Accounting Standards Update No. 2015-01, Income Statement-Extraordinary and Unusual
Items ("ASU No. 2015-01"). ASC Update No. 2015-01 eliminates the concept of extraordinary items found in Subtopic 225-20,
which required that an entity separately classify, present and disclose extraordinary events and transaction when the event or
activity met both criteria of being unusual in nature and infrequent in occurrence. Although the concept of extraordinary items
will be eliminated, the presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be
retained and will be expanded to include items that are both unusual in nature and infrequently occurring. The standard is effective
for fiscal years and interim periods within those fiscal years beginning after December 15, 2015. The Company early adopted
ASU 2015-01 and the adoption had no material effect on its consolidated financial statements and footnote disclosures.

Recently Issued Accounting Standards Not Yet Adopted

In November 2015, the FASB issued Accounting Standards Update No. 2015-17, Income Taxes (Topic 740), Balance Sheet
Classification of Deferred Taxes ("ASU 2015-17"). The objective is to simplify the presentation of deferred income taxes; the
amendments require that deferred tax assets and liabilities be classified as noncurrent in a classified consolidated balance sheets.
ASU 2015-17 will be effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal
years. Earlier application is permitted for all entities as of the beginning of an interim or annual reporting period. The amendment
may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The Company
expects that the adoption of ASU 2015-17 will not materially affect its financial position or results of operations.

In July 2015, the FASB issued Accounting Standards Update No. 2015-11, (Topic 330), Simplifying the Measurement of Inventory
(“ASU 2015-11”). The objective is to reduce the complexity related to inventory subsequent measurement and disclosure
requirements. ASU 2015-11 amendments do not apply to inventory that is measured using last-in, first-out or the retail inventory
method. The amendments apply to all other inventory, which includes inventory that is measured using first-in, first-out or average
cost. Inventory within the scope of the new guidance should be measured at the lower of cost and net realizable value. Net realizable
value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal
and transportation. The amendments more closely align with the measurement of inventory in International Financial Reporting
Standards. ASU 2015-11 will be effective for fiscal years beginning after December 15, 2016, including interim periods within
those fiscal years. The amendments in ASU 2015-11 should be applied prospectively with earlier application permitted as of the
beginning of an interim or annual reporting period. The Company expects that the adoption of ASU 2015-11 will not materially
affect its financial position or results of operations.

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ("ASU
2014-09"). ASU 2014-09 supersedes nearly all existing revenue recognition guidance under generally accepted accounting
principles, generally accepted in the United States of America ("GAAP"). The core principle of ASU 2014-09 is that revenue is
recognized when promised goods or services are transferred to customers in an amount that reflects the consideration to which an
entity expects to be entitled for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle
and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under
existing GAAP. The standard is effective for annual and interim periods beginning after December 15, 2017, using either of the
following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting
period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially
adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). The Company is

currently evaluating the effects of adopting ASU 2014-09 on its consolidated financial statements and has not yet determined the
method by which it will adopt the standard.

Liquidity and Sources of Capital

The Company’s liquidity needs arise principally from working capital requirements, capital expenditures and business acquisitions.
During the three years ended December 31, 2015, the Company relied on internally generated funds to finance these needs. The
Company’s working capital requirements are seasonal with the highest need typically occurring in the second and third quarters
of the year. Cash and cash equivalents were $258.8 million, $260.3 million and $251.2 million at December 31, 2015, 2014 and
2013, respectively. Working capital was $494.3 million, $509.8 million and $464.9 million at December 31, 2015, 2014 and 2013,
respectively. As of December 31, 2015, the Company had no borrowings on its revolving line of credit. At December 31, 2015,
the Company had unused capacity on this and other credit facilities of $304.4 million.

As of December 31, 2015, the Company’s investments consisted of only United States Treasury securities and money market
funds aggregating $76.0 million. Cash collected by the Company’s United States subsidiaries is routinely transferred into cash
management accounts, which typically do not have restrictions on withdrawals. As of December 31, 2015, the Company had $93.2
million, or 36.0%, of its cash and cash equivalents held outside the United States in accounts belonging to several of the Company’s
foreign operating entities. The majority of this balance is held in foreign currencies and could be subject to additional taxation if
it were repatriated to the United States. The Company has no plans to repatriate cash and cash equivalents held outside the United
States as such funds are expected to be used to fund future international growth and acquisitions.

Operating Activities

The Company’s operating activities provided $114.2 million, $67.2 million and $106.5 million in net cash in 2015, 2014 and 2013,
respectively.

In 2015, cash was provided by net income of $67.9 million, noncash expenses totaling $41.7 million, which consisted primarily
of depreciation, amortization, stock-based compensation charges and software development project write-off totaling $3.1 million,
decreases in inventories of $17.2 million and other current assets of $6.3 million and increases in accrued cash profit sharing and
commissions of $2.5 million and income taxes payable of $2.4 million. These increases in cash were offset by an increase in trade
accounts receivable of $16.8 million and decreases in accrued liabilities of $5.1 million, long-term liabilities of $2.9 million and
accounts payable of $1.0 million. The Company’s inventories decreased 9.6% from $216.5 million at December 31, 2014, to
$195.8 million at December 31, 2015, primarily due to increased net sales in the fourth quarter of 2015, which utilized raw materials
at a higher rate compared to the fourth quarter of 2014 and decreased raw material purchases in the fourth quarter of 2015 compared
to the fourth quarter of 2014. The balance of the cash provided resulted from changes in other asset and liability accounts, none
of which was individually material.

In 2014, cash was provided by net income of $63.5 million, noncash expenses totaling $41.1 million, which consisted primarily
of depreciation, amortization and stock-based compensation charges, and increases in other long-term liabilities of $2.6 million
and accrued liabilities of $2.3 million. These increases were offset by increases in inventories of $22.4 million, trade accounts
receivable of $4.6 million and other current assets of $3.7 million and decreases in accounts payable of $11.3 million and income
taxes payable of $0.9 million. The Company’s inventories increased 9.5% from $197.7 million at December 31, 2013, to $216.5
million at December 31, 2014, primarily due to increases in raw materials and increases in in-process and finished goods. The
balance of the cash provided resulted from changes in other asset and liability accounts, none of which was individually material.

In 2013, cash was provided by net income of $51.0 million, noncash expenses totaling $41.3 million, primarily depreciation,
amortization, stock-based compensation charges and impairment of assets, a decrease in inventories of $8.5 million and increases
in income taxes payable of $4.6 million, accrued profit sharing and commissions of $2.6 million and accrued liabilities of $2.1
million. These increases were offset by increases in trade accounts receivable of $6.7 million and decreases in accounts payable
of $2.7 million and other long-term liabilities of $1.0 million. The Company’s inventories decreased 3.1% from $204.1 million
at December 31, 2012, to $197.7 million at December 31, 2013, primarily due to decreases in raw materials, partly offset by
increases in in-process and finished goods. The balance of the cash provided resulted from changes in other asset and liability
accounts, none of which was individually material.

Investing Activities

The Company’s investing activities used $37.8 million, $23.5 million and $17.3 million in net cash in 2015, 2014 and 2013,
respectively.

Cash paid for capital expenditures increased to $34.2 million in 2015 from $23.7 million in 2014, primarily due to a $12.6 million
purchase of a manufacturing facility in West Chicago for the purposes of combining the operations of two leased chemical facilities
into one owned facility. The Company used $7.0 million in 2015 to invest in software development, in excess of $6.0 million to
expand or replace manufacturing capacity, primarily in North America, and in excess of $1.9 million on information technology,
primarily in North America for hardware, software and a new phone system, as well as $1.9 million to increase office space at a
facility in Europe. The balance of the cash used for capital expenditures resulted from numerous purchases, none of which was
individually material. Net cash paid for acquisitions in 2015 totaled $4.2 million. Based on current information and subject to
future events and circumstances, the Company estimates that its capital expenditures for 2016 will be approximately $33.0 million.

In 2014, the Company used $8.5 million to invest in software development, $8.7 million to expand or replace manufacturing
capacity, primarily in North America, and $2.2 million to install a solar roof system on one of the Company's North American
facilities. The balance of the cash used for capital expenditures resulted from numerous purchases, none of which was individually
material. The cash paid for capital expenditures was partly offset by proceeds from the sale of assets of $0.7 million.

In 2013, cash of $17.3 million was used for investing activities, primarily due to $16.8 million of capital expenditures of which
$14.1 million was used to expand and increase manufacturing capacity in North America and the balance of the cash was used
for numerous purchases, none of which was individually material. The cash paid for capital expenditures was partly offset by
proceeds from the sale of assets of $5.3 million and a Keymark-related entity’s repayment of a loan of $0.7 million.

Financing Activities

The Company’s financing activities used $67.9 million, $25.6 million and $13.4 million in net cash in 2015, 2014 and 2013,
respectively.

The Company used net cash in its financing activities in 2015 for the repurchase of the Company’s stock for $47.1 million, the
payment of cash dividends of $29.4 million and for contingent considerations related to an asset acquisitions of $1.2 million. Cash
provided was primarily from issuance of the Company’s common stock on exercise of stock options of $9.7 million.

In 2014, the Company used net cash in its financing activities for the payment of cash dividends of $25.9 million, the repurchase
of the Company’s stock for $3.0 million and for contingent consideration related to an asset acquisition of $1.3 million. Cash
provided was primarily from issuance of the Company’s common stock on exercise of stock options of $4.6 million.

In 2013, the Company used cash for financing activities for the payment of cash dividends of $18.1 million and the repurchase of
the Company’s stock for $9.8 million. Cash provided was primarily from issuance of the Company’s common stock on exercise
of stock options of $15.1 million.

Credit Facilities

In July 2012, the Company entered into an unsecured credit agreement with a syndicate of banks providing for a 5-year revolving
credit facility of $300.0 million, which includes a letter of credit sub-facility of up to $50.0 million. The Company may have the
ability to increase the amount available under the credit agreement by an additional $200.0 million, to a maximum of $500.0
million, if existing lenders or new lenders are willing to make additional commitments and if the Company satisfies certain other
conditions. On any such increase, the pricing for the facility may be subject to change. Amounts borrowed under this credit facility
will bear interest at an annual rate equal to either, at the Company’s option, (a) the rate for Eurocurrency deposits for the
corresponding deposits of U.S. dollars appearing on Reuters LIBOR01screen page (the “LIBOR Rate”), adjusted for any reserve
requirement in effect, plus a spread of 0.60% to 1.45%, determined quarterly based on the Company’s leverage ratio (at
December 31, 2015, the LIBOR Rate was 0.36%), or (b) a base rate, plus a spread of 0.00% to 0.45%, determined quarterly based
on the Company’s leverage ratio. The base rate is defined in a manner such that it will not be less than the LIBOR Rate. The
Company will pay fees for standby letters of credit at an annual rate equal to the LIBOR Rate plus the applicable spread described
above, and will pay market-based fees for commercial letters of credit. The Company is required to pay an annual facility fee of
0.15% to 0.30% of the available commitments under the credit agreement, regardless of usage, with the applicable fee determined
on a quarterly basis based on the Company’s leverage ratio. The Company was also required to pay customary fees as specified
in a separate fee agreement between the Company and Wells Fargo Bank, National Association, in its capacity as the Agent under
the credit agreement.

The proceeds of loans advanced under the credit agreement and letters of credit issued thereunder may be used for working capital
and other general corporate needs of the Company, to pay dividends to the Company’s stockholders or to repurchase outstanding
securities of the Company as permitted by the credit agreement, and to finance acquisitions by the Company permitted by the
credit agreement. No loans or letters of credit are currently outstanding under the credit agreement. The Company and its subsidiaries

are required to comply with various affirmative and negative covenants. The covenants include provisions that would limit the
availability of funds as a result of a material adverse change to the Company’s financial position or results of operations. As of
December 31, 2015, the Company was in compliance with its financial covenants under the credit agreement. The unsecured credit
agreement expires in July 2017.

The Company's purchase obligations consist of commitments primarily related to the acquisition, construction or expansion of
facilities and equipment, consulting agreements, pension fund contributions and minimum purchase quantities of certain raw
materials. The Company currently is not a party to any long-term supply contracts with respect to the purchase of raw materials
or finished goods. Debt interest obligations include interest payments on fixed-term debt, line-of-credit borrowings and annual
facility fees on the Company’s primary line-of-credit facility. Interest on line-of-credit facilities was estimated based on historical
borrowings and repayment patterns. The Company’s primary line-of-credit facility includes annual facility fees from 0.15% to
0.30%, depending on the Company’s leverage ratio, on the unused portion of the facilities.

Off-Balance Sheet Arrangements

The Company did not have any off-balance sheet arrangements as of December 31, 2015.

Contingencies

From time to time, we are subject to legal proceedings and litigation arising in the ordinary course of business. Periodically, we
evaluate the status of each legal matter and assess our potential financial exposure. See “Note 8 — Commitments and Contingencies”
to the Company’s Consolidated Financial Statements.

Inflation

The Company believes that the effect of inflation on the Company has not been material in recent years, as general inflation rates
have remained relatively low. The Company’s main raw material, however, is steel, and increases in steel prices may adversely
affect the Company’s gross profit margins if it cannot recover higher costs through price increases.

Indemnification Provisions

In the normal course of business, the Company indemnifies employees, officers, directors, consultants and third parties with which
the Company has contractual arrangements under terms that may require the Company to make payments in relation to certain
events. The Company has not incurred significant obligations under indemnification provisions historically, and does not expect
to incur significant obligations in the future. Accordingly, the Company has not recorded a liability for these indemnities.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We have operations both within the United States and internationally, and we are exposed to market risks in the ordinary course
of our business.

Foreign Exchange Risk

The Company has foreign exchange rate risk in its international operations, and through purchases from foreign vendors. Changes
in the values of currencies of foreign countries affect our financial position, income statement and cash flows when translated into
U.S. dollars. The Company does not currently hedge this risk. The Company estimates that if the exchange rate were to change
by 10% in any one country where the Company has operations, the change in net income would not be material to the Company’s
operations taken as a whole.

The translation adjustment on the Company's underlying assets and liabilities resulted in a decrease in accumulated other
comprehensive income of $20.9 million for the year ended December 31, 2015, primarily due to the effect of the strengthening
of the United States dollar in relation to all foreign currencies during 2015.

Interest Rate Risk

The Company has no variable interest-rate debt outstanding. The Company estimates that a hypothetical 100 basis point change
in U.S. interest rates would not be material to the Company’s operations taken as a whole.

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders
Simpson Manufacturing Co., Inc.

We have audited the accompanying consolidated balance sheet of Simpson Manufacturing Co., Inc. (a Delaware corporation) and
subsidiaries (the “Company”) as of December 31, 2015, and the related consolidated statements of operations, comprehensive
income, stockholders’ equity, and cash flows for the year then ended. Our audit of the basic consolidated financial statements
included the financial statement schedule listed in the index appearing under Item 15(a)(2). These financial statements and financial
statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these
financial statements and financial statement schedule based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures
in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable
basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position
of Simpson Manufacturing Co., Inc. and subsidiaries as of December 31, 2015, and the results of their operations and their cash
flows for the year then ended in conformity with accounting principles generally accepted in the United States of America. Also
in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements
taken as a whole, presents fairly, in all material respects, the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the
Company’s internal control over financial reporting as of December 31, 2015, based on criteria established in the 2013 Internal
Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO),
and our report dated February 26, 2016 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders
Simpson Manufacturing Co., Inc.

We have audited the internal control over financial reporting of Simpson Manufacturing Co., Inc. (a Delaware corporation) and
subsidiaries (the “Company”) as of December 31, 2015, based on criteria established in 2013 Internal Control-Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s
management is responsible for maintaining effective internal control over financial reporting and for its assessment of the
effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control
over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting
based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control
over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control
over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating
effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in
the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability
of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted
accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain
to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets
of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial
statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that
could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because
of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December
31, 2015, based on criteria established in the 2013 Internal Control-Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the
consolidated financial statements of the Company as of and for the year ended December 31, 2015, and our report dated February
26, 2016 expressed an unqualified opinion on those financial statements.

Simpson Manufacturing Co., Inc. and Subsidiaries
Notes to Consolidated Financial Statements

Operations and Summary of Significant Accounting Policies

Nature of Operations

Simpson Manufacturing Co., Inc., through its subsidiary Simpson Strong-Tie Company Inc. and its other subsidiaries (collectively,
the “Company”), designs, engineers and is a leading manufacturer of wood construction products, including connectors, truss
plates, fastening systems, fasteners and shearwalls, and concrete construction products, including adhesives, specialty chemicals,
mechanical anchors, powder actuated tools and fiber reinforcing materials. The Company markets its products to the residential
construction, industrial, commercial and infrastructure construction, remodeling and do-it-yourself markets.

The Company operates exclusively in the building products industry. The Company’s products are sold primarily in the United
States, Canada, Europe, the South Pacific and in Asia up until 2015 when the Company closed the sales offices there. Revenues
have some geographic market concentration on the west coast of the United States. A portion of the Company’s business is therefore
dependent on economic activity within this region and market. The Company is dependent on the availability of steel, its primary
raw material.

Out-of-Period Adjustment

In the first quarter of 2014, the Company recorded an out-of-period adjustment, which increased gross profit, income from
operations and net income in total by $2.3 million, $2.0 million and $1.3 million, respectively. The adjustment resulted from an
over-statement of prior periods' workers compensation expense, net of cash profit sharing expense, and was not material to the
current period's or any prior period's financial statements.

Principles of Consolidation

The consolidated financial statements include the accounts of Simpson Manufacturing Co., Inc. and its subsidiaries. Investments
in 50% or less owned entities are accounted for using either cost or the equity method. The Company consolidates all variable
interest entities (VIEs) where it is the primary beneficiary. There were no VIEs as of December 31, 2015 or 2014. All significant
intercompany transactions have been eliminated.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United
States of America ("GAAP") 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 Consolidated Financial Statements and the reported
amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Revenue Recognition

The Company recognizes revenue when the earnings process is complete, net of applicable provision for discounts, returns and
incentives, whether actual or estimated based on the Company’s experience. This generally occurs when products are shipped to
the customer in accordance with the sales agreement or purchase order, ownership and risk of loss pass to the customer, collectability
is reasonably assured and pricing is fixed or determinable. The Company’s general shipping terms are F.O.B. shipping point, where
title is transferred and revenue is recognized when the products are shipped to customers. When the Company sells F.O.B. destination
point, title is transferred and the Company recognizes revenue on delivery or customer acceptance, depending on terms of the
sales agreement. Service sales, representing after-market repair and maintenance, engineering activities, software license sales
and service and lease income, though significantly less than 1% of net sales and not material to the Consolidated Financial
Statements, are recognized as the services are completed or the software products and services are delivered. If actual costs of
sales returns, incentives and discounts were to significantly exceed the recorded estimated allowances, the Company’s sales would
be adversely affected.

Sales Incentive and Advertising Allowances

The Company records estimated reductions to revenues for sales incentives, primarily rebates for volume discounts, and allowances
for co-operative advertising.

Allowances for Sales Discounts

The Company records estimated reductions to revenues for discounts taken on early payment of invoices by its customers.

Cash Equivalents

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

Allowance for Doubtful Accounts

The Company assesses the collectability of specific customer accounts that would be considered doubtful based on the customer’s
financial condition, payment history, credit rating and other factors that the Company considers relevant, or accounts that the
Company assigns for collection. The Company reserves for the portion of those outstanding balances that the Company believes
it is not likely to collect based on historical collection experience. The Company also reserves 100% of the amounts that it deems
uncollectable due to a customer’s deteriorating financial condition or bankruptcy. If the financial condition of the Company’s
customers were to deteriorate, resulting in probable inability to make payments, additional allowances may be required.

Inventory Valuation

Inventories are stated at the lower of cost or net realizable value (market). Cost includes all costs incurred in bringing each product
to its present location and condition, as follows:

• Raw materials and purchased finished goods for resale — principally valued at cost determined on a weighted average

•

basis; and
In-process products and finished goods — cost of direct materials and labor plus attributable overhead based on a
normal level of activity.

The Company applies net realizable value and obsolescence to the gross value of the inventory. The Company estimates net
realizable value based on estimated selling price less further costs to completion and disposal. The Company impairs slow-moving
products by comparing inventories on hand to projected demand. If on-hand supply of a product exceeds projected demand or if
the Company believes the product is no longer marketable, the product is considered obsolete inventory. The Company revalues
obsolete inventory to its net realizable value. The Company has consistently applied this methodology. The Company believes
that this approach is prudent and makes suitable impairments for slow-moving and obsolete inventory. When impairments are
established, a new cost basis of the inventory is created. Unexpected change in market demand, building codes or buyer preferences
could reduce the rate of inventory turnover and require the Company to recognize more obsolete inventory.

Warranties and recalls

The Company provides product warranties for specific product lines and records estimated recall expenses in the period in which
the recall occurs, none of which has been material to the Consolidated Financial Statements. In a limited number of circumstances,
the Company may also agree to indemnify customers against legal claims made against those customers by the end users of the
Company’s products. Historically, payments made by the Company, if any, under such agreements have not had a material effect
on the Company’s consolidated results of operations, cash flows or financial position

Fair Value of Financial Instruments

The “Fair Value Measurements and Disclosures” topic of the Financial Accounting Standards Board (“FASB”) Accounting
Standards Codification™ (“ASC”) establishes a valuation hierarchy for disclosure of the inputs used to measure fair value. This
hierarchy prioritizes the inputs into three broad levels as follows: Level 1 inputs are quoted prices (unadjusted) in active markets
for identical assets or liabilities; Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that
are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term
of the financial instrument; Level 3 inputs are unobservable inputs based on the Company’s assumptions used to measure assets
and liabilities at fair value. A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest
level input that is significant to the fair value measurement.

As of December 31, 2015, the Company’s investments consisted of only United States Treasury securities and money market
funds, which are the Company’s primary financial instruments, maintained in cash equivalents and carried at cost, approximating
fair value, based on Level 1 inputs. The balance of the Company’s primary financial instruments was as follows:

(in thousands)

At December 31,

2015

2014

United States Treasury securities and money market funds

76,047 $

99,024

The carrying amounts of trade accounts receivable, accounts payable and accrued liabilities approximate fair value due to the
short-term nature of these instruments. The fair value of the Company’s contingent consideration related to acquisitions is classified
as Level 3 within the fair value hierarchy as it is based on unobserved inputs and assumptions. In 2014, the fair value of the
contingent consideration related to the acquisition of Bierbach GmbH & Co. KG ("Bierbach"), a Germany company, was decreased
from $0.8 million to $0.2 million as a result of not retaining Bierbach's historical customers and increased competition.

Property, Plant and Equipment

Property, plant and equipment are 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, and the resulting gains or losses are reflected in the Consolidated Statements of Operations.

The “Intangibles—Goodwill and Other” topic of the FASB ASC provides guidance on capitalization of the costs incurred for
computer software developed or obtained for internal use. The Company capitalizes qualified external costs and internal costs
related to the purchase and implementation of software projects used for business operations and engineering design activities.
Capitalized software costs primarily include purchased software and external consulting fees. Capitalized software projects are
amortized over the estimated useful lives of the software.

Depreciation and Amortization

Depreciation of software, machinery and equipment is provided using accelerated methods over the following estimated useful
lives:

Software
Machinery and equipment

3 to 5 years
3 to 10 years

Buildings and site improvements are depreciated using the straight-line method over their estimated useful lives, which range
from 15 to 45 years. Leasehold improvements are amortized using the straight-line method over the shorter of the expected life
or the remaining term of the lease. Amortization of purchased intangible assets with finite useful lives is computed using the
straight-line method over the estimated useful lives of the assets.

In-Process Research and Development Assets

In-process research and development (“IPR&D”) assets represent capitalized incomplete research projects that the Company
acquired through business combinations. Such assets are initially measured at their acquisition-date fair values and are required
to be classified as indefinite-lived assets until the successful completion of the associated research and development efforts. During
the development period after the date of acquisition, these assets will not be amortized until the research and development projects
are completed and the resulting assets are ready for their intended use. The Company performs an impairment test annually and
more frequently if events or changes in circumstances indicate it that is more likely than not that the asset is impaired. On successful
completion of the research and development project the Company makes a determination about the then-remaining useful life and
begins amortization.

Cost of Sales

The types of costs included in cost of sales include material, labor, factory and tooling overhead, shipping, and freight costs. Major
components of these expenses are material costs, such as steel, packaging and cartons, personnel costs, and facility costs, such as
rent, depreciation and utilities, related to the production and distribution of the Company’s products. Inbound freight charges,
purchasing and receiving costs, inspection costs, warehousing costs, internal transfer costs, and other costs of the Company’s
distribution network are also included in cost of sales.

Tool and Die Costs

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

Shipping and Handling Fees and Costs

The Company’s general shipping terms are F.O.B. shipping point. Shipping and handling fees and costs are included in revenues
and product costs, as appropriate, in the year incurred.

Product and Software Research and Development Costs

Product research and development costs, which are included in operating expenses and are charged against income as incurred,
were $10.3 million, $11.2 million and $10.7 million in 2015, 2014, and 2013, respectively. The types of costs included as product
research and development expenses are typically related to salaries and benefits, professional fees and supplies. In 2015, 2014
and 2013, the Company incurred software development expenses related to its expansion into the plated truss market and some
of the software development costs were capitalized. See Note 5. The Company amortizes acquired patents over their remaining
lives and performs periodic reviews for impairment. The cost of internally developed patents is expensed as incurred.

Selling Costs

Selling costs include expenses associated with selling, merchandising and marketing the Company’s products. Major components
of these expenses are personnel, sales commissions, facility costs such as rent, depreciation and utilities, professional services,
information technology costs, sales promotion, advertising, literature and trade shows.

Advertising Costs

Advertising costs are included in selling expenses, are expensed when the advertising occurs, and were $6.4 million, $7.3 million
and $7.0 million in 2015, 2014, and 2013, respectively.

General and Administrative Costs

General and administrative costs include personnel, information technology related costs, facility costs such as rent, depreciation
and utilities, professional services, amortization of intangibles and bad debt charges.

Income Taxes

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

Sales Taxes

The Company presents taxes collected and remitted to governmental authorities on a net basis in the accompanying Consolidated
Statements of Operations.

Foreign Currency Translation

The local currency is the functional currency of most of the Company’s operations in Europe, Canada, Asia, Australia, New Zealand
and South Africa. 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 stockholders’ equity. Foreign currency transaction gains or
losses are included in general and administrative expenses.

Sales Office Closing

During the first quarter of 2015, the Company committed to a plan to close its sales offices located in China, Thailand and Dubai
("Asia sales offices"), as well as to reduce its selling activities in Hong Kong, due to continued losses in the regions. As of December
31, 2015, Asia sales offices closures were substantially completed.
78

As of December 31, 2015, the Company had recorded employee severance obligation expenses of $2.4 million and made
corresponding payments totaling $2.1 million. Most of the severance obligation expenses were charged to operating expenses,
with less than $0.6 million recorded to cost of sales. Long-lived assets, consisted mostly of office equipment and vehicles were
fully amortized as of December 31, 2015, total accelerated depreciation expense of $0.2 million was recorded in operating expenses.
All costs associated with the closures were reported in the Asia/Pacific segment.

The following table provides a rollforward of the liability balance for these costs, as well as other non-employee costs associated
with the sales office closing, as of December 31, 2015:

The remaining estimated additional severance expense, retention bonuses and professional fees of $0.3 million will be recorded
as commitment requirements are met or services are performed. In addition, the remaining estimated future minimum lease
obligation of $0.5 million will be charged to expense after the cease-use date, the date the Company ceases to use a lease property.
The estimated costs disclosed are based on a number of assumptions, and actual results could differ materially.

In December 2015, the Company had substantially completed the liquidation of its Asia sales offices, which included liquidating
nearly all of its assets and settling most of its debts. As a result, the Company reclassified $0.2 million of its accumulated other
comprehensive income, related to foreign exchange losses from its Asia sales offices, to its Consolidated Statement of Operations.
This amount is classified as a loss on disposal of assets and was recorded in the Asia/Pacific segment.

Plant Closure

In December 2013, the Company had substantially completed the liquidation of its Irish subsidiary, which included liquidating
nearly all of its assets and settling most of its debts. As a result, the Company reclassified $2.8 million of its accumulated other
comprehensive income, related to foreign exchange losses from its Irish subsidiary, to its Consolidated Statement of Operations.
This amount is classified as a loss on disposal of assets and was recorded in the Administrative & All Other segment.

Sale of Product Line

In December 2013, the Company sold its CarbonWrap product line to The DowAksa USA, LLC for $3.8 million. The CarbonWrap
product line had assets of $2.0 million, consisting of $1.5 million in intangible assets and $0.5 million in goodwill. As part of the
transaction, the Company also incurred severance costs of $0.5 million. As a result of this transaction the Company recognized a
pre-tax gain of $1.4 million.

Because the CarbonWrap assets constituted an integrated business in the United States reporting unit, a portion of the United
States reporting unit’s goodwill was included in the carrying amount of the asset group disposed. The amount of goodwill from
the United States reporting unit included in the CarbonWrap asset group was $0.5 million, which was proportionate to the fair
value of the CarbonWrap asset group compared to the estimated fair value of the United States reporting unit.

The Company continues to invest in related product lines, such as those acquired from Fox Industries, Inc. in 2011 and S&P Clever
Reinforcement Company AG and S&P Clever International AG in 2012, both companies incorporated under the laws of Switzerland
(collectively, “S&P Clever"). See Note 2.

candidate a number of votes equal to the number of directors to be elected multiplied by the number of shares held by such
stockholder or may distribute such stockholder’s votes on the same principle among as many candidates as such stockholder thinks
fit. A director is elected if the votes cast “for” such director’s election exceed the votes cast “against” such director’s election,
except that, if a stockholder properly nominates a candidate for election to the Board, the candidates with the highest number of
affirmative votes (up to the number of directors to be elected) are elected. There are no redemption or sinking fund provisions
applicable to the common stock.

In 1999, the Company declared a dividend distribution of one right per share of our common stock to purchase Series A Participating
preferred stock (each, a "Right," or collectively, the "Rights"). The Rights will be exercisable, unless redeemed earlier by the
Company, if a person or group acquires, or obtains the right to acquire, 15% or more of the outstanding shares of common stock
or commences a tender or exchange offer that would result in it acquiring 15% or more of the outstanding shares of common stock,
either event occurring without the prior consent of the Company. The amount of Series A Participating preferred stock that the
holder of a Right is entitled to receive and the purchase price payable on exercise of a Right are both subject to adjustment. Any
person or group that acquires 15% or more of the outstanding shares of common stock without the prior consent of the Company
would not be entitled to this purchase. Any stockholder who held 25% or more of the Company’s common stock when the Rights
were originally distributed would not be treated as having acquired 15% or more of the outstanding shares unless such stockholder’s
ownership is increased to more than 40% of the outstanding shares.

The Rights will expire on June 14, 2019, or they may be redeemed by the Company at one cent per Right prior to that date. The
Rights do not have voting or dividend rights and, until they become exercisable, have no dilutive effect on the earnings of the
Company. One million shares of the Company’s preferred stock have been designated Series A Participating preferred stock and
reserved for issuance on exercise of the Rights. No event during 2015 made the Rights exercisable.

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
stockholder approval, to issue preferred stock with dividend, redemption, 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.

Stock Repurchase Program

The Company announced a stock repurchase program for 2015 authorizing it to repurchase up to $50.0 million of the Company’s
common stock. The stock repurchase program expired on December 31, 2015.

In September 2015, the Company entered into a Master Confirmation and a Supplemental Confirmation for a $25.0 million
accelerated share repurchase program (the “ASR Agreement”) with Wells Fargo Bank, National Association (“Wells Fargo”). As
of December 31, 2015, the terms of the ASR Agreement was completed. The Company paid Wells Fargo $25.0 million and Wells
Fargo delivered to the Company 689,184 shares of the Company’s common stock, which had an average share price of $36.27
per share. The Company recorded the $25.0 million payment to Wells Fargo as an increase in treasury stock

For the year ended December 31, 2015, the Company purchased a total of 1,338,894 shares of its common stock, which included
the 689,184 shares pursuant to the ASR agreement. The total spent on the 1,338,894 shares during the twelve months ended
December 31, 2015 was approximately $47.1 million, at an average price of $35.21. All of the Company's shares repurchased
during 2015 were retired. See the Consolidated Statements of Stockholders’ Equity.

Net Income per Common Share

Basic net income per common share is computed based on the weighted average number of common shares outstanding. Potentially
dilutive 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 shows a reconciliation of basic earnings per share (“EPS”) to diluted EPS:

Potentially dilutive securities excluded from earnings per diluted share because their
effect is anti-dilutive

—

Anti-dilutive shares attributable to outstanding stock options were excluded from the calculation of diluted net income per share.

The potential tax benefits derived from the amount of the average stock price for the period in excess of the grant date fair value
of stock options, known as the windfall tax benefit, is added to the proceeds of stock option exercises under the treasury stock
method for computing the amount of dilutive securities used to determine the outstanding shares for the calculation of diluted
earnings per share.

Comprehensive Income or Loss

Comprehensive income is defined as net income plus other comprehensive income or loss. Other comprehensive income or loss
consists of changes in cumulative translation adjustments and changes in unamortized pension adjustments recorded directly in
accumulated other comprehensive income within stockholders’ equity. The following shows the components of accumulated other
comprehensive income or loss as of December 31, 2015 and 2014, respectively:

The 2013 and 2015 translation adjustments activity included the realization of $2.8 million in cumulative currency translation
adjustments related to the liquidation of the Irish subsidiary and $0.2 million in cumulative currency translation adjustments related
to the liquidation of the Asia sales offices, both as a net loss on disposal of assets in the Consolidated Statements of Operations.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash in banks, short-term
investments in United States Treasury securities, money market funds and trade accounts receivable. The Company maintains its
cash in demand deposit and money market accounts held primarily at seventeen banks.

Accounting for Stock-Based Compensation

With the approval of the Company’s stockholders on April 26, 2011, the Company adopted the Simpson Manufacturing Co., Inc.
2011 Incentive Plan (the “2011 Plan”). The 2011 Plan amended and restated in their entirety, and incorporated and superseded,
both the Simpson Manufacturing Co., Inc. 1994 Stock Option Plan (the “1994 Plan”), which was principally for the Company’s
employees, and the Simpson Manufacturing Co., Inc. 1995 Independent Director Stock Option Plan (the “1995 Plan”), which was
for its independent directors. Awards previously granted under the 1994 Plan or the 1995 Plan will not be affected by the adoption
of the 2011 Plan and will continue to be governed by the 1994 Plan or the 1995 Plan, respectively.

Under the 1994 Plan, the Company could grant incentive stock options and non-qualified stock options, although the Company
granted only non-qualified stock options under the 1994 Plan and the 1995 Plan. The Company generally granted options under
each of the 1994 Plan and the 1995 Plan once each year. Options vest and expire according to terms established at the grant date.
Stock options granted under the 1994 Plan typically vested evenly over the requisite service period of four years and have a term
of seven years. Options granted under the 1995 Plan were fully vested on the date of grant. Shares of common stock issued on
exercise of stock options under the 1994 Plan and the 1995 Plan are registered under the Securities Act of 1933.

Under the 2011 Plan, the Company may grant incentive stock options, non-qualified stock options, restricted stock and restricted
stock units, although the Company currently intends to award primarily restricted stock units and to a lesser extent, if at all, non-
qualified stock options. The Company does not currently intend to award incentive stock options or restricted stock. Under the
2011 Plan, no more than 16.3 million shares of the Company’s common stock may be issued (including shares already sold)
pursuant to all awards under the 2011 Plan, including on exercise of options previously granted under the 1994 Plan and the 1995
Plan. Shares of common stock to be issued pursuant to the 2011 Plan are registered under the Securities Act of 1933.

The stock-based compensation expense included in cost of sales, research and development and engineering expense, selling
expense, or general and administrative expense depends on the job functions performed by the employees to whom the stock
options were granted, or the restricted stock units were awarded.

The assumptions used to calculate the fair value of options or restricted stock units are evaluated and revised, as necessary, to
reflect market conditions and the Company’s experience. See Note 12.

Goodwill Impairment Testing

The reporting unit level is generally one level below the operating segment and is at the country level except for the United States,
Denmark, Australia, and S&P Clever reporting units.

The Company has determined that the United States reporting unit includes four components: Northwest United States, Southwest
United States, Northeast United States and Southeast United States (collectively, the “U.S. Components”). The Company aggregates
the U.S. Components into a single reporting unit because management concluded that they are economically similar and that the
goodwill is recoverable from the U.S. Components working in concert. The U.S. Components are economically similar because
of a number of factors, including, selling similar products to shared customers and sharing assets and services such as intellectual
property, manufacturing assets for certain products, research and development projects, manufacturing processes, management
of inventory excesses and shortages and administrative services. These activities are managed centrally at the U.S. Components
level and costs are allocated among the four U.S. Components.

The Company has determined that the S&P Clever reporting unit includes eight components: S&P Switzerland, S&P Poland, S&P
Austria, S&P The Netherlands, S&P Portugal, S&P Germany, S&P France and S&P Nordic (collectively, the "S&P Components”).
The Company aggregates the S&P Components into a single reporting unit because management concluded that they are
economically similar and that the goodwill is recoverable from the S&P Components working in concert. The S&P Components
are economically similar because of a number of factors, including sharing assets and services such as intellectual property,
manufacturing assets for certain products, research and development projects, manufacturing processes, management of inventory
excesses and shortages and administrative services. These activities are managed centrally at the S&P Components level and costs
are allocated among the S&P Components.

For certain reporting units, the Company may first assess qualitative factors related to the goodwill of the reporting unit to determine
whether it is necessary to perform a two-step impairment test. If the Company judges that it is more likely than not that the fair
value of the reporting unit is greater than the carrying amount of the reporting unit, including goodwill, no further testing is required.
If the Company judges that it is more likely than not that the fair value of the reporting unit is less than the carrying amount of
the reporting unit, including goodwill, management will perform a two-step impairment test on goodwill. In the first step ("Step
1"), the Company compares the fair value of the reporting unit to its carrying value. The fair value calculation uses the income
approach (discounted cash flow method) and the market approach, equally weighted. If the Company judges that the carrying
value of the net assets assigned to the reporting unit, including goodwill, exceeds the fair value of the reporting unit, a second step
of the impairment test must be performed to determine the implied fair value of the reporting unit’s goodwill. If the Company
judges that the carrying value of a reporting unit’s goodwill exceeds its implied fair value, the Company would record an impairment
charge equal to the difference between the implied fair value of the goodwill and the carrying value.

The 2015, 2014 and 2013 annual testing of goodwill for impairment did not result in impairment charges. The impairment charge
taken in the third quarter of 2014 was associated with assets in the Germany reporting unit acquired from Bierbach in 2013. See
Note 2. The factors that led to the third quarter impairment were a failure to retain Bierbach's historical customers and increased
competition factors, which led to the reduction in the contingent consideration liability related to the Bierbach acquisition, and
resulted in management performing an impairment test to evaluate the recoverability of the Germany reporting unit's goodwill.
The test resulted in the impairment of all of the reporting unit’s goodwill in the amount of $0.5 million. In connection with the
impairment of the goodwill, the Company also reviewed associated long-lived assets in Germany, such as property and equipment
and intangible assets, for recoverability by comparing the projected undiscounted net cash flows associated with those assets to
their carrying values. No impairment of long-lived assets was required as a result of that review during the third quarter of 2014.

The Denmark reporting unit passed Step 1 of the annual 2015 impairment test by a 9% margin indicating an estimated value greater
than its net book value and was the only reporting unit with a fair value greater than net book value margin of less than 10%. The
Denmark reporting unit is sensitive to management’s plans for retaining or replacing lost sales and operating margins. The Denmark
reporting unit’s failure to meet management’s objectives could result in future impairment of some or all of the Denmark reporting
unit’s goodwill, which was $6.4 million at December 31, 2015.

Key assumptions used in Step 1 of the Company’s annual goodwill impairment test included compound annual growth rates
(“CAGR”) and average annual pre-tax operating margins during the forecast period, and discount rates. A sensitivity assessment
for the key assumptions included in the Denmark reporting unit annual goodwill impairment test is as follows:

• A 480 basis point hypothetical change in the discount rate, holding all other assumptions constant, would not have
decreased the fair value of the reporting unit below its carrying value, and thus it would not result in the reporting unit
failing Step 1 of the goodwill impairment test.

• A 105 basis point hypothetical decrease in the CAGR, holding all other assumptions constant, would not have decreased

the fair value of the reporting unit below its carrying value.

• A 40% hypothetical decrease in average annual pre-tax operating profit, holding all other assumptions constant, would

not have decreased the fair value of the reporting unit below its carrying value.

Recently Adopted Accounting Standards

In September 2015, the FASB issued Accounting Standards Update No. 2015-16, (Topic 805), Simplifying the Accounting for
Measurement-Period Adjustments (“ASU 2015-16”). ASU 2015-16 amendments eliminate the requirement to restate prior period
financial statements for measurement period adjustments made to provisional amounts recognized in a business combination. The
new guidance requires that the cumulative impact of measurement period adjustments (including the impact on prior periods) be
recognized in the reporting period in which the adjustments are determined. The amendments require preparers to present cumulative
adjustments separately within the respective financial line items affected or disclose in the notes the amount recorded in current-
period earnings. The new guidance does not change what constitutes a measurement period adjustment. The new standard should
be applied prospectively to measurement period adjustments that occur after the effective date. The new standard is effective for
interim and annual periods beginning after December 15, 2015, with early adoption permitted. The Company early adopted this
guidance effective December 15, 2015, and the adoption had no material effect on its consolidated financial statements and footnote
disclosures.

In April 2015, the FASB issued Accounting Standards Update No. 2015-05 (Subtopic 340-40), Customer’s Accounting for Fees
Paid in a Cloud Computing Arrangement (“ASU 2015-05"). The guidance in this Subtopic applies only to internal-use software
that a customer obtains access to in a hosted arrangement. The amendments provide guidance to customers about whether a cloud
computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the
customer should account for the software license element of the arrangement consistent with the acquisition of other software
licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement
as a service contract. With an election to adopt prospectively or retrospectively, this ASU will be effective for annual periods
beginning after December 15, 2015. The Company early adopted ASU 2015-11 prospectively and the adoption had no material
effect on its consolidated financial statements and footnote disclosures.

In January 2015, the FASB issued Accounting Standards Update No. 2015-01, Income Statement-Extraordinary and Unusual
Items ("ASU 2015-01"). ASU 2015-01 eliminates the concept of extraordinary items found in Subtopic 225-20, which required
that an entity separately classify, present and disclose extraordinary events and transaction when the event or activity met both
criteria of being unusual in nature and infrequent in occurrence. Although the concept of extraordinary items will be eliminated,
the presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and will be
expanded to include items that are both unusual in nature and infrequently occurring. The standard is effective for fiscal years and
interim periods within those fiscal years beginning after December 15, 2015. The Company early adopted ASU 2015-01 and the
adoption had no material effect on its consolidated financial statements and footnote disclosures.

Recently Issued Accounting Standards Not Yet Adopted

In November 2015, the FASB issued Accounting Standards Update No. 2015-17, Income Taxes (Topic 740), Balance Sheet
Classification of Deferred Taxes (ASU 2015-17). The objective is to simplify the presentation of deferred income taxes; the
amendments require that deferred tax assets and liabilities be classified as noncurrent in a classified consolidated balance sheets.

ASU 2015-17 will be effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal
years. Earlier application is permitted for all entities as of the beginning of an interim or annual reporting period. The amendment
may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The Company
expects that the adoption of ASU 2015-17 will not materially affect its financial position or results of operations.

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ("ASU
2014-09"). ASU 2014-09 supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of ASU
2014-09 is that revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the
consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five-step process to
achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process
than are required under existing GAAP. The standard is effective for annual and interim periods beginning after December 15,
2017, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard
in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative
effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). The
Company is currently evaluating the effects of adopting ASU 2014-09 on its consolidated financial statements and has not yet
determined the method by which it will adopt the standard.

2. Acquisitions

In February 2013, the Company purchased certain assets relating to the TJ® ShearBrace (“ShearBrace”) product line of
Weyerhaeuser NR Company (“Weyerhaeuser”), a Washington corporation, for $5.3 million in cash. The ShearBrace is a line of
pre-fabricated shearwalls that complements the Company’s Strong-Wall shearwall, and is sold throughout North America. The
Company’s measurement of assets acquired included goodwill of $2.6 million which was assigned to the North America segment
and intangible assets of $1.9 million both of which are subject to tax-deductible amortization. Net tangible assets consisting of
inventory and equipment accounted for the balance of the purchase price. The weighted-average amortization period for the
intangible assets is 13.4 years.

In November 2013, the Company purchased certain assets related to a connector product line from Bierbach GmbH & Co. KG
(“Bierbach”), a Germany corporation, for $1.2 million in cash and a contingent liability of $0.8 million. Bierbach manufactured
and sold a line of connectors, primarily in Germany. The Company’s measurement of assets acquired included goodwill of $0.5
million, which was assigned to the Europe segment, and intangible assets of $0.6 million, both of which are subject to tax-deductible
amortization. Net tangible assets consisting of inventory and tool and dies accounted for the balance of the purchase price. At the
end of 2014, the Company reduced the fair value of the contingent consideration liability from $0.8 million to $0.2 million due
to a failure to retain Bierbach's historical customers and increased competition, which resulted in a $0.5 million gain that was
reported in general and administrative expenses in the Consolidated Statements of Operations. The goodwill associated with
Bierbach was fully impaired during 2014. (See Note 1 "Operations and Summary of Significant Accounting Policies - Goodwill
Impairment Testing"). The weighted-average amortization period for the intangible assets is 9.7 years.

In December 2015, the Company purchased all of the business assets including intellectual property from Blue Heron Enterprises,
and Fox Chase Enterprises, LLC (collectively, "EBTY"), both New Jersey limited liability companies, for $3.4 million in cash.
EBTY manufactured and sold hidden deck clips and products and systems using a patented design. EBTY's patented design for
hidden deck clips and products and systems will complement the Company's line of hidden clips and fastener systems. The
Company's provisional measurement of assets acquired included goodwill of $2.0 million which was assigned to the North American
segment, and intangible assets of $1.1 million both of which are subject to tax-deductible amortization. Net assets consisting of
inventory and equipment accounted for the balance of the purchase price. The weighted-average amortization period for the
intangible assets is 7 years.
88

Under the business combinations topic of the FASB ASC, the Company accounted for these acquisitions as business combinations
and ascribed acquisition-date fair values to the acquired assets and assumed liabilities. Fair value of intangible assets was based
on Level 3 inputs.

The results of operations of the businesses acquired in 2013 through 2015 are included in the Company’s consolidated results of
operations since the date of the acquisition. They were not material to the Company on an individual or aggregate basis, and
accordingly, pro forma results of operations have not been presented.

Included in property, plant and equipment at December 31, 2015 and 2014, are fully depreciated assets with an original cost of
$156.7 million and $161.1 million, respectively. These fully depreciated assets are still in use in the Company’s operations.

In December 2015, the Company purchased for $12.6 million a manufacturing facility in West Chicago for the purposes of
combining the operations of its two leased chemical facilities into one owned facility. The Company estimates 2016 costs to
complete improvements to operate out of the new facility will be $7.0 million to $10.0 million.

The Company capitalizes certain development costs associated with internal use software, including external direct costs of
materials and services and payroll costs for employees devoting time to a software project. As of December 31, 2015 and 2014,
depreciable capitalized software development costs were $1.6 million and $1.8 million, respectively, and included in capital
projects in progress at December 31, 2015 and 2014, were software in development costs of $12.2 million and $8.3 million,
respectively. Costs incurred during the preliminary project stage, as well as costs for maintenance and training, are expensed as
incurred.

Depreciation expense was $20.4 million for both years ended December 31, 2015 and 2014,and was $20.1 million for the year
ended December 31, 2013.

The Company has revolving lines of credit with various banks in the United States and Europe. Total available credit at December 31,
2015 was $304.4 million, including revolving credit lines and an irrevocable standby letter of credit in support of various insurance
deductibles.

The Company’s primary credit facility is a revolving line of credit with $300.0 million in available credit. This credit facility will
expire in July 2017. Amounts borrowed under this credit facility will bear interest at an annual rate equal to either, at the Company’s
option, (a) the rate for Eurocurrency deposits for the corresponding deposits of U.S. dollars appearing on Reuters LIBOR1screen
page (the “LIBOR Rate”), adjusted for any reserve requirement in effect, plus a spread of 0.60% to 1.45%, determined quarterly
based on the Company’s leverage ratio (at December 31, 2015, the LIBOR Rate was 0.36% ), or (b) a base rate, plus a spread of
0.00% to 0.45%, determined quarterly based on the Company’s leverage ratio. The base rate is defined in a manner such that it
will not be less than the LIBOR Rate. The Company will pay fees for standby letters of credit at an annual rate equal to the LIBOR
Rate plus the applicable spread described above, and will pay market-based fees for commercial letters of credit. The Company
is required to pay an annual facility fee of 0.15% to 0.30% of the available commitments under the credit agreement, regardless
of usage, with the applicable fee determined on a quarterly basis based on the Company’s leverage ratio. The Company was also
required to pay customary fees as specified in a separate fee agreement between the Company and Wells Fargo Bank, National
Association, in its capacity as the Agent under the credit agreement.

The Company’s borrowing capacity under other revolving credit lines and a term note totaled $4.4 million at December 31, 2015.
The other revolving credit lines and term note charge interest ranging from 0.67% to 7.50% and have maturity dates from
March 2016 to December 2016. The Company had no outstanding balance at December 31, 2015 and $18 thousand outstanding
at December 31, 2014, respectively.

The Company and its subsidiaries are required to comply with various affirmative and negative covenants. The covenants include
provisions that would limit the availability of funds as a result of a material adverse change to the Company’s financial position
or results of operations. The Company was in compliance with its financial covenants under the loan agreement as of December 31,
2015.

The Company incurs interest costs, which include interest, maintenance fees and bank charges. The amount of costs incurred,
capitalized, and expensed for the years ended December 31, 2015, 2014 and 2013, consisted of the following:

Certain properties occupied by the Company are leased. The leases expire at various dates through 2023 and generally require the
Company to assume the obligations for insurance, property taxes and maintenance of the facilities.

Rental expense for 2015, 2014 and 2013 with respect to all leased property was approximately $6.6 million, $6.9 million and $6.9
million, respectively.

At December 31, 2015, minimum rental commitments under all non-cancelable leases were as follows:

Some of these minimum rental commitments contain renewal options and provide for periodic rental adjustments based on changes
in the consumer price index or current market rental rates. Other rental commitments provide options to cancel early without
penalty. Future minimum rental payments, under the earliest cancellation options, are included in minimum rental commitments
in the table above.

Other Contractual Obligations

Purchase obligations consist of commitments primarily related to the acquisition, construction or expansion of facilities and
equipment, consulting agreements, and minimum purchase quantities of certain raw materials. The Company is not a party to any
long-term supply contracts with respect to the purchase of raw materials or finished goods. Debt interest obligations include interest
payments on fixed-term debt, line-of-credit borrowings and annual facility fees on the Company’s primary line-of-credit facility.
Interest on line-of-credit facilities was estimated based on historical borrowings and repayment patterns.

Approximately 13% of the Company’s employees are represented by labor unions and are covered by collective bargaining
agreements. The Company’s facility in San Bernardino County, California, has two of the Company's collective bargaining
agreements, one with tool and die craftsmen and maintenance workers, and the other with sheetmetal workers. These two contracts
expire in February 2017 and June 2018, respectively. The Company’s facility in Stockton, California, is also a union facility with
two collective bargaining agreements, which also cover tool and die craftsmen and maintenance workers and sheetmetal workers.
These two contracts will expire in July and September 2019, respectively.

Environmental

The Company’s policy with regard to environmental liabilities is to accrue for future environmental assessments and remediation
costs when information becomes available that indicates that it is probable that the Company is liable for any related claims and
assessments and the amount of the liability is reasonably estimable. The Company does not believe that any such matters will
have a material adverse effect on the Company’s financial condition, cash flows 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.
At this time, the Company is not a party to any legal proceedings, which the Company expects individually or in the aggregate to
have a material adverse effect on the Company’s financial condition, cash flows or results of operations. Nonetheless, the resolution
of any claim or litigation is subject to inherent uncertainty and could have a material adverse effect on the Company’s financial
condition, cash flows or results of operations.

The total deferred tax assets as of December 31, 2015 and 2014, were $22.6 million and $22.0 million, respectively. The total
deferred tax liabilities as of December 31, 2015 and 2014, were $20.5 million and $16.8 million, respectively.

At December 31, 2015, the Company had $31.1 million of pre-tax loss carryforwards in various non-United States taxing
jurisdictions, which includes approximately $5.9 million that were generated by the Company’s Beijing and Thailand subsidiaries
that are in the process of liquidating. Tax loss carryforwards of $0.7 million, $1.6 million, $1.4 million, $2.3 million and $1.7
million will expire in 2016, 2017, 2018, 2019 and 2020, respectively, if not used. The remaining tax losses can be carried forward
indefinitely.

At December 31, 2015, and 2014, the Company had deferred tax valuation allowances of $7.6 million and $6.8 million, respectively.
The valuation allowance increased $0.8 million and $1.3 million for the years ended December 31, 2015 and 2014, respectively.

The Company does not provide for federal income taxes on the undistributed earnings of its international subsidiaries because
such earnings are reinvested and, in the Company’s opinion, will continue to be reinvested indefinitely. At December 31, 2015,
2014 and 2013, the Company had not provided for federal income taxes on undistributed earnings of $51.6 million, $45.6 million
and $34.8 million, respectively, from its international subsidiaries. Should these earnings be distributed in the form of dividends
or otherwise, the Company would be subject to both United States income taxes and withholding taxes in various international
jurisdictions. These taxes may be partially offset by United States foreign tax credits. Determination of the related amount of
unrecognized deferred United States income taxes is not practicable because of the complexities associated with this hypothetical
calculation. United States federal income taxes are provided on the earnings of the Company’s foreign branches, which are included
in the United States federal income tax return.

A reconciliation of the beginning and ending amounts of unrecognized tax benefits in 2015, 2014 and 2013, respectively, was as
follows, including foreign translation amounts:

Reconciliation of Unrecognized Tax Benefits
Balance at January 1
Additions based on tax positions related to prior years
Reductions based on tax positions related to prior years

Included in the balance of unrecognized tax benefits at December 31, 2015, 2014 and 2013, are tax positions of $0.2 million, $0.0
million and $0.7 million, respectively, which, if recognized, would reduce the effective tax rate.

The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense, which is a
continuation of the Company’s historical accounting policy. During the years ended December 31, 2015, 2014 and 2013, accrued
interest decreased by $30 thousand, $0.2 million and $0.3 million, respectively, as a result of the reversal of accrued interest
associated with the lapses of statutes of limitations. The Company had accrued $0.2 million both at December 31, 2015 and 2014,
and $0.4 million at December 31, 2013, for the potential payment of interest, before income tax benefits.

At December 31, 2015, the Company remained subject to United States federal income tax examinations for the tax years 2012
through 2015. In addition, the Company remained subject to state, local and foreign income tax examinations primarily for the
tax years 2010 through 2015.

10. Retirement Plans

The Company has five defined contribution retirement plans covering substantially all salaried employees and nonunion hourly
employees. On January 1, 2015, the Simpson Manufacturing Co., Inc. 401(k) Profit Sharing Plan for Salaried Employees was
amended, restated and superseded by the Simpson Manufacturing Co., Inc. 401(k) Profit Sharing Plan (the “Restated Plan”), and
the Simpson Manufacturing Co., Inc. 401(k) Profit Sharing Plan for Hourly Employees was merged with and incorporated into
the Restated Plan. The Restated Plan, covering United States employees, provides for quarterly contributions, limited to 3% of
the employees quarterly eligible compensation, that does not require Board approval and for annual contributions in amounts that
the Board authorizes, subject to certain limitations, but in no event are total contributions more than the amounts permitted under
the Internal Revenue Code as deductible expense. The other four plans, covering the Company’s European and Canadian employees,
require the Company to make contributions ranging from 3% to 15% of the employees’ compensation. The total cost for these
retirement plans for the years ended December 31, 2015, 2014 and 2013, was $9.5 million, $8.0 million and $8.2 million,
respectively.

The Company also contributes to various industry-wide, union-sponsored pension funds for hourly employees who are union
members and a statutorily required pension fund for employees in Switzerland. Payments to these funds aggregated $2.5 million,
$2.3 million and $2.2 million for the years ended December 31, 2015, 2014 and 2013, respectively.

Settlement of Pension Withdrawal Liability

Under the Company's collective bargaining arrangement with the tool and die craftsman and maintenance union, the Company
has been contributing to a defined-benefit pension plan. In 2014, the Company and the union formally notified the defined-benefit
pension plan administrator of their intent to withdraw from the plan. In the third quarter of 2014, the plan administrator responded
by issuing a demand letter informing the Company that the annual withdrawal liability payment to be made by the Company was
$145,400 and the payments were to be made in perpetuity.

Due to the amount and duration of payments, the Company was required to calculate and record a pension expense and liability
based on the annual payments in perpetuity. At December 31, 2014, the Company discounted the payment estimate using a discount
rate of 4.5%, which approximates the credit-adjusted risk-free rate for the Company and recorded a long-term liability of $3.3
million with a corresponding defined-benefit expense in cost of sales. On a quarterly basis, the Company re-evaluated the number
of years that payments are required and the discount rate used to calculate the long-term liability and adjusted it as facts and
95

circumstances changed. All adjustments to the long-term liability were charged to cost of sales in the Consolidated Statements of
Operations. Because of the funding status of the plan, the annual withdrawal liability payments were recorded as interest expense
on the long-term liability.

In September of 2015, the defined-benefit pension plan trustees and the Company agreed to settle this long-term pension withdrawal
liability, which at the time had a $3.0 million balance, for $2.0 million. As a result of the settlement, the Company reduced the
long-term pension withdrawal liability by $1.0 million with a corresponding defined benefit expense reduction in cost of sales.
The $2.0 million long-term pension withdrawal liability was fully paid as of September 30, 2015.

11. Related Party Transactions

In March 2013, the Company extended its lease on a property in Addison, Illinois, which is co-owned by Gerald Hagel, a vice
president of Simpson Strong-Tie Company Inc. since March 2007. The extension is for an additional five years through 2018. The
Company paid $0.3 million in 2013 to lease the property from Mr. Hagel and his wife, Susan Hagel, a former employee of Simpson
Strong-Tie Company Inc.

In 2015, the Company paid Tacit Knowledge, Inc. ("Tacit Knowledge"), a consultant on a software implementation project, $2.1
million for its services. The Company did not make payments to Tacit Knowledge prior to 2015. The project is continuing in 2016.
Chris Andrasick, the Company's Director James S. Andrasick’s son, co-founded Tacit Knowledge in 2002. Tacit Knowledge was
sold to Newgistics, Inc. ("Newgistics") in 2013. Chris Andrasick was hired by Newgistics in 2013, as their Chief Strategy and
Innovation Officer for Digital Commerce, and he remained interim Chief Executive Officer for Tacit Knowledge into 2015, but
he had no financial interest in Tacit Knowledge since the 2013 acquisition other than in his role as an officer of Newgistics. The
payments that the Company made to Tacit Knowledge in 2015 were less than one-half of one percent of Newgistics's consolidated
gross revenues for the fiscal year ended December 31, 2015.

12. Stock-Based Compensation Plans

The Company has one stock-based incentive plan, the 2011 Plan, which incorporates and supersedes its two previous plans except
for awards previously granted under the two plans (see Note 1 — Accounting for Stock-Based Compensation). Participants are
generally granted stock-based awards only if the applicable Company-wide or profit-center operating goals, or both, or strategic
goals, established by the Compensation and Leadership Development Committee of the Board of Directors at the beginning of
the year, are met.

The fair value of each restricted stock unit award is estimated on the date of the award based on the closing market price of the
underlying stock on the day preceding the date of the award, excluding the present value of the dividends that the restricted
stock units do not participate in. On February 1, 2016, 431,439 restricted stock units were awarded at an estimated value of
$32.63 per share, the closing price on January 29, 2016. The restrictions on these awards generally lapse one quarter on each of
the date of the award and the first, second and third anniversaries of the date of the award. Restrictions on certain awards to
each of the Company's named executive officers and certain members of the Company's senior management lapse fully on the
third anniversary of the date of the award. On April 21, 2015, 1,950 restricted stock units were awarded to each of the
Company’s six non-employee directors at a value of $36.33 per share based on the closing price on April 20, 2015. There are
no restrictions on the non-employee directors’ restricted stock units granted on April 21, 2015.

The following table summarizes the Company’s unvested restricted stock unit activity for the year ended December 31, 2015:

* The intrinsic value represents the amount by which the fair market value of the underlying common stock exceeds the exercise
price of the option, using the closing price per share of $34.15, as reported by the New York Stock Exchange on December 31,
2015.

The total intrinsic value of stock options exercised during the three years ended December 31, 2015, 2014 and 2013, was $2.4
million, $0.8 million and $2.6 million, respectively.

As of January 1, 2015, there were 99 thousand unvested stock options with a weighted average grant-date fair value of $10.33 per
share. These stock options vested in the first quarter of 2015 and, as of December 31, 2015, the Company had no unvested stock
options.

As of December 31, 2015, total unrecognized compensation cost of $17.2 million was related to unvested stock-based compensation
arrangements under the 2011 Plan for awards made through February 2015 and those expected to be made through February 2016.
The portion of this cost related to restricted stock units awarded through February 2015 is expected to be recognized over a
weighted-average period of 2 years.

The Company also maintains a Stock Bonus Plan whereby it awards shares to employees, who do not otherwise participate in one
of the Company’s stock-based incentive plans. The number of shares awarded, as well as the period of service, is determined by
the Compensation and Leadership Development Committee of the Board. The Company committed to issuing 10 thousand shares
for 2015 and issued 16 thousand and 11 thousand shares for 2014 and 2013, respectively, which resulted in pre-tax compensation
charges of $0.7 million, $0.9 million and $0.7 million for the years ended December 31, 2015, 2014 and 2013, respectively. These
employees are also awarded cash bonuses, which are included in these charges, to compensate for their income taxes payable as
a result of the stock bonuses. Shares have been issued under this plan in the year following the year in which the employee reached
the tenth anniversary of employment with the Company.

13. Segment Information

The Company is organized into three reporting segments. The segments are defined by the regions where the Company’s products
are manufactured, marketed and distributed to the Company’s customers. The three regional segments are the North America
segment, comprising primarily the United States and Canada, the Europe segment and the Asia/Pacific segment, comprising the
Company’s operations in Asia, the South Pacific and South Africa. These segments are similar in several ways, including the types
of materials, the production processes, the distribution channels and the product applications.

The Administrative & All Other column primarily includes expenses such as self-insured workers compensation claims for
employees of the Company’s venting business, which was sold in 2010, stock-based compensation for certain members of
management, interest expense, foreign exchange gains or losses and income tax expense, as well as revenues and expenses related
to real estate activities, such as rental income and depreciation expense on the Company’s property in Vacaville, California, which
the Company has leased to a third party for a 10-year term expiring in August 2020.

The following table shows certain measurements used by management to assess the performance of the segments described above
as of December 31, 2015, 2014 and 2013, respectively:

Cash collected by the Company’s United States subsidiaries is routinely transferred into the Company’s cash management accounts,
and therefore has been included in the total assets of “Administrative & All Other.” Cash and short-term investment balances in
“Administrative & All Other” were $164.1 million, $167.4 million and $156.0 million as of December 31, 2015, 2014 and 2013,
respectively. As of December 31, 2015, the Company had $93.2 million, or 36.0%, of its cash and cash equivalents held outside
the United States in accounts belonging to the Company’s various foreign operating entities. The majority of this balance is held
in foreign currencies and could be subject to additional taxation if it were repatriated to the United States. The Company has no

international growth and acquisitions.

The significant non-cash charges comprise compensation related to the awards under the stock-based incentive plans and the stock
bonus plan. The Company’s measure of profit or loss for its reportable segments is income (loss) from operations. The reconciling
amounts between consolidated income before tax and consolidated income from operations are net interest income, which is
primarily attributed to “Administrative & All Other.”

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosures.

During the fiscal year ended December 31, 2015 and through the date of this Annual Report on Form 10-K, there have been no
transactions or events as described under Item 304(b) of Regulation S-K.

Item 9A. Controls and Procedures.

Disclosure Controls and Procedures. As of December 31, 2015, the Company carried out an evaluation, under the supervision
and with the participation of the Company’s management, including the chief executive officer (“CEO”) and the chief financial
officer (“CFO”), of the effectiveness of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) under
the Exchange Act. Disclosure controls and procedures are controls and other procedures designed reasonably to assure that
information required to be disclosed in the Company’s reports filed or submitted under the Exchange Act, such as this Annual
Report on Form 10-K, is recorded, processed, summarized and reported within the time periods specified in the Securities and
Exchange Commission’s rules and forms. Disclosure controls and procedures are also designed reasonably to assure that this
information is accumulated and communicated to the Company’s management, including the CEO and the CFO, as appropriate
to allow timely decisions regarding required disclosure. Based on this evaluation, as of December 31, 2015, the Company's CEO
and CFO have concluded that the Company's disclosure controls and procedures were effective at the reasonable assurance level.

Management’s Report on Internal Control over Financial Reporting. The Company’s management is responsible for establishing
and maintaining adequate internal control over financial reporting. The Company’s management assessed the effectiveness of the
Company’s internal control over financial reporting as of December 31, 2015, using the criteria established in Internal Control -
Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) and
concluded that the Company's internal control over financial reporting was effective as of December 31, 2015. Grant Thornton
LLP, an independent registered public accounting firm that audited the Company’s consolidated financial statements included in
this Annual Report on Form 10-K, has also audited the effectiveness of the Company’s internal control over financial reporting
as of December 31, 2015, as stated in their report which is included Part II, Item 8, "Financial Statements and Supplementary
Data" of this Annual Report on Form 10-K.

Changes in Internal Control over Financial Reporting. There were no changes in our internal control over financial reporting
identified in management's evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the three months
ended December 31, 2015 that materially affected, or are reasonably likely to materially affect, our internal control over financial
reporting.

Inherent Limitations of Disclosure Controls and Procedures and Internal Control over Financial Reporting. The Company’s
management, including the CEO and the CFO, does not, however, expect that the Company’s disclosure controls and procedures
or the Company’s internal control over financial reporting will necessarily prevent all fraud and material errors. Internal control
over financial reporting, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that
the objectives of the control system are met. In addition, the design of a control system must reflect the facts that there are resource
constraints and that the benefits of controls must be considered relative to their costs. The inherent limitations in internal control
over financial reporting include the realities that judgments can be faulty and that breakdowns can occur because of simple error
or mistake. Controls also can be circumvented by the individual acts of some persons, by collusion of two or more people, or by
management override of controls. The design of any system of internal control is also based in part on assumptions about the
likelihood of future events, and there can be only reasonable, not absolute, assurance that any design will succeed in achieving its
stated goals under all potential events and conditions. Over time, controls may become inadequate because of changes in
circumstances, or the degree of compliance with the policies and procedures may deteriorate.
