Notes to Condensed Consolidated Financial Statements
(Unaudited)
1. Basis of Presentation
Principles of Consolidation
The accompanying condensed consolidated financial statements include the accounts of Simpson Manufacturing Co., Inc. and its subsidiaries (collectively, the “Company”). Investments in 50% or less owned entities are accounted for using either cost or the equity method. All significant intercompany transactions have been eliminated.
Use of Estimates
The preparation of the 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. Management believes that these consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation under GAAP. We assessed certain accounting matters that require the use of estimates and assumptions in context with the known and projected future impacts of COVID-19. The Company's actual results could differ materially from those estimates.
Interim Reporting Period
The accompanying unaudited quarterly condensed consolidated financial statements have been prepared pursuant to the rules and regulations for reporting on Form 10-Q. Accordingly, certain information and footnotes required by GAAP have been condensed or omitted. These interim statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (the “2020 Form 10-K”).
The unaudited quarterly condensed consolidated financial statements have been prepared on the same basis as the audited annual consolidated financial statements and, in the opinion of management, contain all adjustments (consisting of only normal recurring adjustments) necessary to state fairly the financial information set forth therein in accordance with GAAP. Certain prior period amounts in the condensed consolidated financial statements and the accompanying notes have been reclassified to conform to the current period’s presentation. The year-end condensed consolidated balance sheet data provided herein were derived from audited financial statements included in the 2020 Form 10-K, but do not include all disclosures required by GAAP. The Company’s quarterly results fluctuate. As a result, the Company believes the results of operations for this interim period presented are not indicative of the results to be expected for any future periods.
Revenue Recognition
Generally, the Company’s revenue contract with a customer exists when goods are shipped, and services (if any) are rendered; and its related invoice is generated. The duration of the contract does not extend beyond the promised goods or services already transferred. The transaction price of each distinct promised product or service specified in the invoice is based on its relative stated standalone selling price. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product to a customer at a point in time. The Company’s shipping terms provide the primary indicator of the transfer of control. The Company’s general shipping terms are F.O.B. shipping point, where title and risk and rewards of ownership transfer at the point when the products leave the Company’s warehouse. The Company recognizes revenue based on the consideration specified in the invoice with a customer, excluding any sales incentives, discounts, and amounts collected on behalf of third parties (i.e., governmental tax authorities). Based on historical experience with the customer, the customer's purchasing pattern and its significant experience selling products, the Company concluded that a significant reversal in the cumulative amount of revenue recognized will not occur when the uncertainty (if any) is resolved (that is, when the total amount of purchases is known). Refer to Note 2 for additional information.

Net Income Per Common Share
The Company calculates net income per common share based on the weighted-average number of shares of the Company's common stock outstanding during the period. Potentially dilutive securities are included in the diluted per-share calculations using the treasury stock method for all periods when the effect is dilutive.
Accounting for Leases
The Company has operating leases for certain facilities, equipment, and autos. As an accounting policy for short-term leases, the Company elected to not recognize the right-of-use asset and liability, if, at the commencement date, the lease (1) has a term of 12 months or less and (2) does not include renewal and purchase options that the Company is reasonably certain to exercise. Monthly payments on short-term leases are recognized on the straight-line basis over the full lease term.
Accounting for Stock-Based Compensation
The Company recognizes stock-based compensation expense related to the estimated fair value of restricted stock awards on a straight-line basis, net of estimated forfeitures, over the requisite service period of the awards, which is generally the vesting term of four years. Stock-based expense related to performance share grants are measured based on grant date fair value and expensed on a graded basis over the service period of the awards, which is generally a performance period of three years. The performance conditions are based on the Company's achievement of revenue growth and return on invested capital over the performance period, and are evaluated for the probability of vesting at each reporting period end with changes in expected results recognized as an adjustment to expense. The assumptions used to calculate the fair value of restricted stock grants are evaluated and revised, as necessary, to reflect market conditions and the Company’s experience.
Fair Value of Financial Instruments
Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. Assets and liabilities recorded at fair value are measured and classified under a three-tier fair valuation hierarchy based on the observability of the inputs available in the market: 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; and Level 3 inputs are unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The carrying amounts of trade accounts receivable, accounts payable, accrued liabilities and other current 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 and equity investment are classified as Level 3 within the fair value hierarchy as it is based on unobserved inputs such as management estimates and entity-specific assumptions and is evaluated on an ongoing basis. The fair value of foreign currency forward contracts, calculated based on Level 1 inputs, was not material as of June 30, 2021.
Derivative Instruments - Foreign Currency Contracts
The Company uses derivative instruments as a risk management tool to mitigate the potential impact of certain market risks. Foreign currency exchange rate risk is the primary market risk the Company manages through the use of derivative instruments, which are accounted for as cash flow hedges under the accounting standards and carried at fair value as other current assets or other current liabilities in the consolidated balance sheets. Net deferred gains and losses related to changes in fair value are included in accumulated other comprehensive loss, a component of shareholders' equity in the consolidated balance sheets, and are reclassified into the line item in the consolidated statement of income in which the hedged items are recorded in the same period the hedged item affects earnings. Changes in fair value of any derivatives that are determined to be ineffective are immediately reclassified from other comprehensive income into earnings. The cash flow impact of the Company's derivative instruments is primarily included in the consolidated statement of cash flows in net cash provided by operating activities. Refer to Note 8.
10

Cash and Cash Equivalents
The Company classifies investments that are highly liquid and have maturities of three months or less at the date of purchase as cash equivalents. As of June 30, 2021 and 2020, the value of these investments were $57.1 million and $76.9 million, respectively, consisting of U.S. Treasury securities and money market funds. The value of the investments is based on cost, which approximates fair value based on Level 1 inputs.
Current Estimated Credit Loss - Allowance for doubtful accounts
The Company maintains an allowance for doubtful accounts receivable for estimated future expected credit losses resulting from customers' failure to make payments on its accounts receivable. The Company determines the estimate of the allowance for doubtful accounts receivable by considering several factors, including (1) specific information on the financial condition and the current creditworthiness of customers, (2) credit rating, (3) payment history and historical experience, (4) aging of the accounts receivable, and (5) reasonable and supportable forecasts about collectability. The Company also reserves 100% of the amounts deemed uncollectible due to a customer's deteriorating financial condition or bankruptcy.
Every quarter, the Company evaluates the customer group using the accounts receivable aging report and its best judgment when considering changes in customers' credit ratings, level of delinquency, customers' historical payments and loss experience, current market and economic conditions, and expectations of future market and economic conditions.
The changes in the allowance for doubtful accounts receivable for the year ended June 30, 2021 are outlined in the table below:

| Balance at |  |  | Balance at
(in thousands) | December 31, 2020 | Expense (Deductions), net | Write-Offs 1 | June 30, 2021
Allowance for Doubtful Accounts | $ | 2,110 |  | (377) |  | 287 |  | $ | 1,446 |

1 Amount is net of recoveries and the effect of foreign currency fluctuations for the year ended June 30, 2021.
Income Taxes
The Company uses an estimated annual tax rate to measure the tax benefit or tax expense recognized in each interim period.
Accounting Standards Not Yet Adopted
In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-04, Reference Rate Reform (Topic 848). ASU 2020-04 provides optional guidance to ease the potential burden in accounting for reference rate reform on financial reporting in response to the risk of cessation of the London Interbank Offered Rate (“LIBOR”) on December 31, 2021. The ASU allows the option to account for and present a modification that meets the scope of the standard as an event that does not require contract remeasurement at the modification date or reassessment of a previous accounting determination required under the relevant topic or subtopic. Entities are permitted to apply the amendments to all contracts, cash flow and net investment hedge relationships that exist as of March 12, 2020. The relief provided in this ASU is only available for a limited time, generally through December 31, 2022. The Company's primary credit facility is the $300 million revolving line of credit (the "Credit Facility") with Wells Fargo Bank, which matures on July 12, 2026. Borrowings under the Credit Facility bear interest using LIBOR plus an applicable margin. The Credit Facility currently includes a provision for the determination of a successor LIBOR rate or an alternative rate of interest.
On March 5, 2021, ICE Benchmark Administration, the administrator of the LIBOR and the Financial Conduct Authority, announced some USD LIBOR tenors (overnight, 1 month, 3 month, and 12 month) will continue to be published until June 30, 2023. We do not expect a material impact to our consolidated operating results, financial position or cash flow from the transition from LIBOR to alternative reference interest rates, but we will continue to monitor the impact of the transition until it is completed.
All issued and effective accounting standards during the second quarter of 2021 were determined to be not relevant or material to the Company.

2. Revenue from Contracts with Customers
Disaggregated revenue
The Company disaggregates net sales into the following major product groups as described in the footnote for segment information included in these interim financial statements under Note 14.
Wood Construction Products Revenue. Wood construction products represented 87% and 86% of total net sales in the six months ended June 30, 2021 and 2020, respectively.
Concrete Construction Products Revenue. Concrete construction products represented 13% and 14% of total net sales in the six months ended June 30, 2021 and 2020, respectively.
Customer acceptance criteria. Generally, there are no customer acceptance criteria included in the Company's standard sales agreement with customers. When an arrangement with the customer does not meet the criteria to be accounted for as a revenue contract under the standard, the Company recognizes revenue in the amount of nonrefundable consideration received when the Company has transferred control of the goods or services and has stopped transferring (and has no obligation to transfer) additional goods or services. The Company offers certain customers discounts for paying invoices ahead of the due date, which are generally between 30 to 60 days after the issue date.
Other revenue. Service sales, representing after-market repair and maintenance, engineering activities and software license sales and services were less than 1.0% of net sales and recognized as the services are completed or by transferring control over a product to a customer at a point in time. Services may be sold separately or in bundled packages. The typical contract length for a service is generally less than one year. For bundled packages, the Company accounts for individual services separately when they are distinct within the context of the contract. A distinct service is separately identifiable from other items in the bundled package if a customer can benefit from the service on its own or with other resources that are readily available to the customer. The consideration (including any discounts) is allocated between separate services in a bundle based on their relative stand-alone selling prices. The stand-alone selling prices are determined based on the prices at which the Company separately sells the services.
Reconciliation of contract balances
Contract assets are the rights to consideration in exchange for goods or services that the Company has transferred to a customer when that right is conditional on something other than the passage of time. Contract liabilities are recorded for any services billed to customers and not yet recognizable if the contract period has commenced or for the amount collected from customers in advance of the contract period commencing. As of June 30, 2021, the Company had no contract assets or contract liabilities from contracts with customers.

4. Stockholders' Equity
Treasury Shares
As of June 30, 2021, the Company held 150,974 shares of its common stock as treasury shares.
5. Stock-Based Compensation
The Company allocates stock-based compensation expense related to equity plans for employees and non-employee directors among the cost of sales, research and development and other engineering expense, selling expense, or general and administrative expense based on the job functions performed by the employees or non-employee directors to whom the stock-based compensation is awarded. The Company recognized stock-based compensation expense related to its equity plans for employees of $3.3 million and $5.2 million for the three months June 30, 2021 and 2020, respectively, and $9.8 million and $5.4 million for the six months ended June 30, 2021 and 2020.
During the six months ended June 30, 2021, the Company granted 133,717 restricted stock units ("RSUs") to the Company's employees, including officers at an estimated weighted average fair value of $100.93 per share based on the closing price (adjusted for the present value of dividends) of the Company's common stock on the grant date. The RSUs granted to the Company's employees may be performance-based and/or time-based. Certain performance-based RSUs are granted to officers and key employees, where the number of performance-based awards to be issued is based on the achievement of certain Company performance criteria established in the RSU agreement over a cumulative three-year period. These awards cliff vest after three years. In addition, these same officers and key employees also receive time-based RSUs, which vest pursuant to a three-year graded vesting schedule. Time-based RSUs that are granted to the Company's employees excluding officers and certain key employees, vest ratably over the four year vesting-term of the award.
The Company’s seven non-employee directors are entitled to receive approximately $690 thousand in equity compensation annually. The number of shares ultimately granted are based on the average closing share price for the Company over the 60 day period prior to approval of the award in the second quarter of each year. In May and June 2021, the Company granted 6,601 shares of the Company's common stock to the non-employee directors, based on the average closing price of $114.60 per share and recognized a total expense of $756 thousand.
As of June 30, 2021, the Company's aggregate unamortized stock compensation expense was approximately $21.3 million, which is expected to be recognized in expense over a weighted-average period of 2.5 years.

8. Derivative Instruments
The Company transacts business in various foreign countries and may therefore be exposed to foreign currency exchange rate risk. The Company has established risk management programs to protect against volatility in the value of non-functional future cash flows caused by changes in foreign currency exchange rates and tries to maintain a partial or fully hedged position for certain transaction exposures when management considers appropriate. The Company enters into short-term foreign currency derivatives contracts, namely forward contracts, to hedge only those currency exposures associated with cash flows denominated in non-functional currencies. Gains and losses on the Company's derivative contracts are designed to offset losses and gains on the transactions hedged, and accordingly, generally do not subject the Company to risk of significant accounting losses. The Company hedges committed exposures and does not engage in speculative transactions. The credit risk of these derivative contracts is minimized since the contracts are with a large financial institution and accordingly, fair value adjustments related to the credit risk of the counterparty financial institution are not material.
The Company sources certain materials for its concrete products from a wholly owned subsidiary in China, and as a result is exposed to variability in cash outflows associated with changes in the foreign exchange rate between the U.S. Dollar and the Chinese Yuan (CNY). As of June 30, 2021, the aggregate notional amount of the Company's outstanding foreign currency derivative contracts was to buy CNY36.9 million by selling $5.4 million throughout fiscal 2021. These forward contracts are accounted for as cash flow hedges under the accounting standards, and fair value is included in other current assets or other current liabilities, as applicable, in the consolidated balance sheet was $0.2 million.
Net deferred gains and losses on these contracts relating to changes in fair value are included in accumulated other comprehensive income or loss ("OCI"), a component of shareholders' equity in the consolidated balance sheets, and are reclassified into the line item in the consolidated statement of income in which the hedged items are recorded in the same period the hedged item affects earnings. For the six months ended June 30, 2021, gains on these contracts of $0.2 million was recognized, as a reduction of cost of sales. Changes in fair value of any forward contracts that are determined to be ineffective are immediately reclassified from OCI into earnings. The amounts deferred in OCI are expected to be recognized as a component of cost of sales in the consolidated statement of operations from 2021 to 2022. There were no amounts recognized due to ineffectiveness during the six months ended June 30, 2021.

11. Leases
Operating Lease Obligations
The Company has operating leases for certain facilities, equipment and autos. The existing operating leases expire at various dates through 2025, some of which include options to extend the leases for up to 5 years. The Company measured the lease liability at the present value of the lease payments to be made over the lease term. The lease payments are discounted using the Company's incremental borrowing rate. The Company measured the right-of-use ("ROU") assets at the amount at which the lease liability is recognized plus initial direct costs incurred or prepayment amounts. The ROU assets are amortized on a straight-line basis over the lease term.
The following table provides a summary of leases included on the condensed consolidated balance sheets as of June 30, 2021 and 2020 and December 31, 2020, condensed consolidated statements of earnings and comprehensive income, and condensed consolidated statements of cash flows as of three and six months ended June 30, 2021 and 2020:

13. Commitments and Contingencies
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 and Potential Claims
From time to time, the Company is involved in various legal proceedings and other matters arising in the normal course of business. Corrosion, hydrogen embrittlement, 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 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.
Gentry Homes, Ltd. v. Simpson Strong-Tie Company Inc., et al., Case No. 17-cv-00566, was filed in a federal district court in Hawaii against Simpson Strong-Tie Company Inc. and the Company on November 20, 2017. The Gentry case is a product of a previous state court class action, Nishimura v. Gentry Homes, Ltd., et al., Civil No. 11-1-1522-07, which is now closed. The Nishimura case concerned alleged corrosion of the Company’s galvanized “hurricane straps” and mudsill anchor products used in a residential project in Ewa by Gentry, Honolulu, Hawaii. In the Nishimura case, the plaintiff homeowners and the developer, Gentry Homes, Ltd. (“Gentry”), arbitrated their dispute and agreed on a settlement in the amount of approximately $90 million. In the subsequent Gentry case, Gentry alleges breach of warranty and negligent misrepresentation by the Company related to its “hurricane strap” and mudsill anchor products. At this time, the Company and the plaintiffs have reached a settlement in principle and are currently negotiating a definitive written agreement memorializing the settlement. Should the parties be unable to reach an accord on terms of the written agreement, further negotiations may take place that could result in a different settlement, or the case may continue on to trial. Based on the facts currently known, and subject to future events and
19

circumstances, the Company believes that all or part of the damages for the claims brought against it in the Gentry case may be covered by its insurance policies.

Overview
We design, manufacture and sell building construction products that are of high quality and performance, easy to use and cost-effective for customers. We operate in three business segments determined by geographic region: North America, Europe and Asia/Pacific.
22

At our March 23, 2021 analyst and investor day, we unveiled several key growth initiatives that we believe will help us continue our track record of above market revenue growth through a combination of organic and inorganic opportunities. Our organic opportunities are focused on expansion into new markets within our core competencies of wood and concrete products. These growth initiatives will focus on the original equipment manufacturers, repair and remodel or do-it-yourself, mass timber, concrete and structural steel markets.
In order to grow in these markets, we aspire to be among the leaders in engineered load-rated construction building products and systems and customer-facing technology while leveraging our engineering expertise, deep-rooted relationships with top builders, engineers, contractors, code officials and distributors, along with our ongoing commitment to testing, research and innovation. Importantly, we currently have existing products, testing results, distribution and manufacturing capabilities for five targeted areas for growth. Although these initiatives are all currently in different stages of development our successful growth in these areas will ultimately be a function of expanding our sales and/or marketing functions to promote our products to different end users and distribution channels, expanding our customer base, and potentially introducing new products in the future.
Also during the March analyst and investor day, we highlighted our Five-year Ambitions, which are as follows:
1.Strengthen our values-based culture;
2.Be the business partner of choice;
3.Strive to be an innovative leader in our product categories;
4.Continue above market growth relative to the U.S. housing starts;
5.Remain within the top quartile of our proxy peers for operating income margins; and
6.Remain in the top quartile of our proxy peers for return on invested capital.
As with our growth initiatives, we expect to make periodic updates related to material developments with our Five-year Ambitions.
A novel strain of coronavirus (“COVID-19”) surfaced in late 2019 and has spread around the world, including to the United States. In March 2020, the World Health Organization declared COVID-19 a worldwide pandemic and the President of the United States declared the COVID-19 outbreak a national emergency. As of June 30, 2021, the effects of and responses to the pandemic continue to have a significant impact on worldwide economic activity and on macroeconomic conditions. Vaccines are available in various countries and distribution of the vaccine also varies by country and in the U.S. by state. The duration and severity of the effects of the pandemic are still unknown and cannot be predicted with any certainty. Notwithstanding the Company's continued efforts to promote the health and safety of our employees, suppliers and customers, as the COVID-19 pandemic continues, health concern risks remain. It also remains unclear how various national, state, and local governments will react if the distribution of vaccines is slower than expected or new variants of the virus become more prevalent.
In response to the pandemic, government authorities in the countries and states where we operate have issued various and differing shelter in place and stay at home orders, social distancing guidelines, mask mandates and other measures in response to the COVID-19 pandemic. In many of those locations our operations are classified as an "essential business" and we continue to operate our business in compliance with applicable state and local laws and are observing recommended CDC guidelines to minimize the risk of spreading the COVID-19 virus. We have undertaken numerous steps and instituted additional precautions to protect our employees, suppliers and customers, as their safety and well-being is one of our top priorities, and to comply with health and safety guidelines. These steps and precautions include enhanced deep cleaning, staggered shifts, temperature checking, use of face masks, practicing social distancing and limiting non-employees at our locations, amongst other safety related policies and procedures. Although vaccines are available where we operate, health concern risks remain and it is possible the COVID-19 pandemic could further impact our operations and the operations of our suppliers and vendors particularly in light of variant strains of COVID-19 that may cause a resumption of high levels of infection and hospitalization.
The Company’s management team continues to monitor and manage its ability to operate effectively and, to date, the Company has not experienced any significant disruptions within its supply chain. Our supply chain partners have been very supportive and continue to do their part to ensure that service levels to our customers remain strong and, to date, we have not experienced any supply-chain disruptions and continued to meet our customers’ needs despite the challenges presented by the pandemic. We will continue to communicate with our supply chain partners to identify and mitigate risk and to manage inventory levels.

In response to the COVID-19 pandemic the Company proactively took measures to maintain and preserve its strong financial position and flexibility. The Company's Crisis Management Team, which includes members of senior management, meets regularly to review and assess the status of the Company's operations and the health and safety of its employees.
The Company’s business, financial condition and results of operations depends significantly on the level of U.S. housing starts and residential construction activity. Though single-family housing starts increased significantly from prior-year's level, we believe there is uncertainty that demand will increase in the short-term due to a number of supply-chain factors affecting new home completion. With recent sales price increases, we believe net sales will likely increase in future periods even if demand does not decrease. However, increased selling prices are expected to be offset by increasing material costs, sourcing logistics complications and a tight labor market, which could negatively affect operating margins for the remainder of 2021.
Since June 2020, inventory pounds in North America, which is the bulk of our inventory, decreased 23% while the weighted average cost per pound of total on hand increased approximately 49%. Over the next 12 to 18 months, steel cost increases are expected to result in lowering operating margins by 300 to 400 basis points from 2021.
Management continues to monitor the impact of the global situation on the Company's financial condition, liquidity, operations, suppliers, industry, and workforce.
Factors Affecting Our Results of Operations
Unlike lumber or other products that have a more direct correlation to U.S. housing starts, our products are used to a greater extent in areas that are subject to natural forces, such as seismic or wind events. Our products are generally used in a sequential process that follows the construction process. Residential and commercial construction begins with the foundation, followed by the wall and the roof systems, and then the installation of our products, which flow into a project or a house according to these schedules.
Our sales also tend to be 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 a fiscal year, as our customers tend to purchase construction materials in the late spring and summer months for the construction season. Weather conditions, such as extended cold or wet weather, which affect and sometimes delay installation of some of our products, could negatively affect our results of operations. Political, economic events such as tariffs and the possibility of additional tariffs on imported raw materials or finished goods or such as labor disputes can also have an effect on our gross and operating profits as well as the amount of inventory on-hand. Our operations can also be affected by a volatile steel market. Changes in raw material cost could negatively affect our gross profit and operating margins depending on the timing of raw material purchases or how much sales prices can be increased to offset higher raw material costs.
Our operations also expose us to risks associated with pandemics, epidemics or other public health emergencies, such as the COVID-19 pandemic.
ERP Integration
In July 2016, our Board of Directors approved a plan to replace our current in-house enterprise resource planning (“ERP”) and externally sourced accounting platforms with a fully integrated ERP platform from SAP America, Inc. (“SAP”) in multiple phases by location at all facilities plus our headquarters, with a focus on configuring, instead of customizing, the standard SAP modules.
We went live with our first wave of the SAP implementation project in February of 2018, and completed implementation at our North America operations in 2021. We expect to complete the company-wide SAP implementation during 2022. While we believe the SAP implementation will be beneficial to the Company over time, annual operating expenses have and are expected to continue to increase through 2024 as a result of the SAP implementation, primarily due to increases in training costs and the depreciation of previously capitalized costs.
Business Segment Information
Historically our North America segment has generated more revenues from wood construction products compared to concrete construction products. Our wood construction product net sales increased 23.2% for the quarter ended June 30, 2021 compared to June 30, 2020, primarily due to higher product prices. Our concrete construction product net sales increased 15.2% for the quarter ended June 30, 2021 compared to June 30, 2020, primarily due to higher product prices. Operating profits increased due
24

to higher sales and gross margins, partly offset by higher operating expenses primarily for personnel costs and professional fees. If current economic conditions continue and factoring in recently announced sales price increases, we believe North America operating margins could be higher in 2021 compared to 2020. However, increased steel costs, product sourcing complications and a tight labor market will likely result in lower operating margins in the second half of 2021.
Our Europe segment also generates more revenues from wood construction products than concrete construction products. Europe net sales increased for the quarter ended June 30, 2021 compared to June 30, 2020, primarily due to higher sales volumes in local currency and were positively affected by approximately $5.3 million in foreign currency translation related to Europe's currencies strengthening against the United States dollar. Wood construction product sales increased 53.7% for the quarter ended June 30, 2021 compared to June 30, 2020. Concrete construction product sales are mostly project based, and net sales increased 40.6% for the quarter ended June 30, 2021 compared to June 30, 2020. Gross margins increased, mostly due to lower labor, factory, warehouse and shipping costs, partly offset by higher material costs. Operating expenses increased, primarily due to increased personnel costs. If current economic conditions continue and factoring in recently announced sales price increases, we believe Europe operating margins could be higher in 2021 compared to 2020. However, increased steel costs and product sourcing complications could offset increased sales, negatively affecting operating margins towards the end of 2021 through 2022.
Our Asia/Pacific segment has generated revenues from both wood and concrete construction products. We believe that the Asia/Pacific segment is not significant to our overall performance.
Business Outlook
On July 26, 2021, the Company provided a full-year outlook. The Company updated its full year outlook, primarily reflecting actual results of the second quarter, as well as improved visibility on the pandemic-related restrictions and the impact of those restrictions on the Company’s operations. Based on current business trends and conditions, the Company's outlook for the full fiscal year ending December 31, 2021 is as follows:
•Operating margin is estimated to be in the range of 19.5% to 21.0%.
•The effective tax rate is estimated to be in the range of 25.0% to 26.0%, including both federal and state income tax rates.
•Capital expenditures are estimated to be in the range of $55 million to $60 million.

Gross profit increased 28.4% to $358.7 million from $279.5 million. Gross profit margins increased to 47.3% from 45.8%, primarily due to lower labor costs and factory expense as well as product price increases implemented during the second quarter, partly offset by higher material costs, warehouse, and shipping expense each as a percentage of net sales. The gross profit margins, including some inter-segment expenses, which were eliminated in consolidation, and excluding other expenses that are allocated according to product group, increased to 47.0% from 45.8% for wood construction products and increased to 45.2% from 42.4% for concrete construction products.
Research and development and engineering expense increased 12.5% to $28.8 million from $25.6 million primarily due to increases of $1.5 million in in personnel costs, $0.8 million in professional fees and $0.4 million in patent costs.
Selling expense increased to $64.0 million from $55.4 million, primarily due to increases of $6.8 million in personnel costs and sales commissions, $3.0 million in professional fees, $1.0 million in stock-based compensation, and $0.4 million cash profit sharing expense, partly offset by decreases of $1.0 million in advertising and promotional expense, $0.6 million travel-related expenses and $0.4 million software development costs being capitalized.
General and administrative expense increased to $96.0 million from $77.1 million, primarily due to increases of $6.0 million in professional fees, including consulting fees, $4.9 million in personnel costs, $3.6 million in stock-based compensation, $2.5 million in cash profit sharing expenses and $1.6 million in depreciation and amortization expenses. Included in general and administrative expense are costs associated with the SAP implementation and support of $9.3 million, an increase of $3.4 million over the first six-months of 2020.
Our effective income tax rate increased to 25.8% from 24.0%.
Consolidated net income was $122.9 million compared to $90.3 million. Diluted net income per common share was $2.82 compared to $2.05.

Effect of New Accounting Standards
See "Note 1 Basis of Presentation — Not Yet Adopted Accounting Standards” to the accompanying unaudited interim condensed consolidated financial statements.
Liquidity and Sources of Capital
In July 2021, the Company entered into a fourth amendment to the unsecured credit agreement dated July 27, 2012 with Wells Fargo Bank, National Association, and certain other institutional lenders that provides for a $300.0 million unsecured revolving credit facility (“Credit Facility”). The amendment extends the term of the Credit Facility from July 23, 2022, to July 12, 2026
31

and modified certain covenants to provide us with additional flexibility. As of June 30, 2021, the full $300 million on the Credit Facility was available for borrowing and we remain debt free.
Our principal uses of liquidity include the costs and expenses associated with our operations, including financing working capital requirements and continuing our capital allocation strategy, which includes supporting capital expenditures, repurchasing the Company's common stock, paying cash dividends, and financing other investment opportunities over the next twelve months.
As of June 30, 2021, our cash and cash equivalents consisted of deposits and money market funds held with established national financial institutions. Cash and cash equivalents of $67.7 million are held in the local currencies of our foreign operations and could be subject to additional taxation if repatriated to the United States. The Company is maintaining a permanent reinvestment assertion on its foreign earnings relative to remaining cash held outside the United States.
The following table presents selected financial information as of June 30, 2021, December 31, 2020 and June 30, 2020, respectively:

|  | At June 30, |  | At December 31, |  | At June 30,
(in thousands) |  | 2021 |  | 2020 |  | 2020
Cash and cash equivalents |  | $ | 305,796 |  |  | $ | 274,639 |  |  | $ | 315,448 |
Property, plant and equipment, net |  | 255,353 |  |  | 255,184 |  |  | 247,119 |
Goodwill, intangible assets and other |  | 164,511 |  |  | 165,110 |  |  | 156,957 |
Working capital less cash and cash equivalents |  | 363,453 |  |  | 284,439 |  |  | 326,040 |

The following table provides cash flow indicators for the six-month periods ended June 30, 2021 and 2020, respectively:

|  | Six Months Ended June 30,
(in thousands) |  | 2021 |  | 2020
Net cash provided by (used in): |  |  |  |
Operating activities |  | $ | 81,632 |  |  | $ | 42,766 |
Investing activities |  | (26,214) |  |  | (13,444) |
Financing activities |  | (25,603) |  |  | 57,733 |

Cash flows from operating activities result primarily from our earnings, and are also affected by changes in operating assets and liabilities which consist primarily of working capital balances. Our revenues are derived from manufacturing and sales of building construction materials. Our operating cash flows are subject to seasonality and are cyclically associated with the volume and timing of construction project starts. For example, trade accounts receivable is generally at its lowest at the end of the fourth quarter and increases during the first, second and third quarters.
During the six months ended June 30, 2021, operating activities provided $81.6 million in cash and cash equivalents, as a result of $122.9 million from net income and $41.2 million from reversing non-cash expenses from net income, which included depreciation and amortization expense and stock-based compensation expense. Cash provided from net income was partly offset by a decrease of $82.7 million in the net change in operating assets and liabilities, including increases of $84.7 million in trade accounts receivable, $27.3 million in inventory and $14.8 million in other current assets, partly offset by increases of $35.9 million in other current liabilities and $10.8 million in trade accounts payable.
Cash used in investing activities of $26.2 million during the six months ended June 30, 2021 was mainly for capital expenditures and a $6.8 million investment in a venture capital fund. Our capital spending in 2019, 2020 and the six months ended June 30, 2021 was $37.5 million, $37.9 million and $19.3 million, respectively, which was primarily used for machinery and equipment purchases and software in development. Based on current information and subject to future events and circumstances, we expect new capital spending for fiscal year 2021 will be in the $55 million to $60 million range which includes carryover projects from 2020 that were paused due to COVID-19 concerns. Capital spending will be primarily for safety needs, equipment replacement and productivity improvements. At this time only a small amount of capital spending is related to our growth initiatives.
32

Cash used in financing activities of $25.6 million during the six months ended June 30, 2021 consisted primarily of $20.0 million used to pay dividends to our stockholders and $5.3 million used to pay income taxes on behalf of the employees for shares withheld with respect to their vested restricted stock units.
On July 14, 2021, the Board declared a quarterly cash dividend of $0.25 per share payable on October 28, 2021, to the Company's stockholders of record on October 7, 2021. The Board also approved changing our capital return threshold from 50% of our cash flow from operations to 50% of our free cash flow, which is calculated by subtracting capital expenditures from cash flow from operations. For the six months ended June 30, 2021, we have returned $20 million of our free cash flow to stockholders.
As illustrated in the table below, from 2015 to 2020, the Company returned cash of $637.7 million in stock repurchases and dividends, which represented 70.2% of our total cash flow from operations during the same period. The Company has repurchased over 7.7 million shares of the Company's common stock since the beginning of 2015, which represents approximately 15.7% of the outstanding shares of the Company's common stock.

(in thousands) | Number of Shares Repurchased |  | Cash Paid for Share Repurchases |  | Cash paid for Dividends |  | Total
January 1 - December 31, 2020 | 1,053 |  |  | 76,189 |  |  | 40,400 |  |  | 116,589 |
January 1 - December 31, 2019 | 972 |  |  | 60,816 |  |  | 40,258 |  |  | 101,074 |

January 1 - December 31, 2017 | 1,138 |  |  | 70,000 |  |  | 36,981 |  |  | 106,981 |
January 1 - December 31, 2016 | 1,244 |  |  | 53,502 |  |  | 32,711 |  |  | 86,213 |
January 1 - December 31, 2015 | 1,339 |  |  | 47,144 |  |  | 29,352 |  |  | 76,496 |
Total | 7,701 |  |  | $ | 418,191 |  |  | $ | 219,593 |  |  | $ | 637,784 |

During the month of July, 2021, the Company repurchased 182,752 shares of the Company's common stock in the open market at an average price of $109.44 per share, for a total of $20.0 million. For the seven months ending July 31, 2021, the Company returned $40.0 million of our free cash flow to our stockholders.
Off-Balance Sheet Arrangements
We did not have any off-balance sheet arrangements as of June 30, 2021.
Inflation and Raw Materials
We believe that the effect of inflation has not been material in recent years, as general inflation rates have remained relatively low. However, the cost of steel, lumber and petroleum products have increased in the last few quarters as had housing prices on strong demand, especially for new housing compared to a limited supply. This could have an effect on the general inflation rates in future quarters. Our main raw material is steel. As such, increased steel prices may adversely affect our gross profit margin if we cannot recover the higher costs through price increases in a timely manner, which is reflected in the Business Outlook section above.
Item 3. Quantitative and Qualitative Disclosures About Market Risk.
We have operations both within the United States and internationally, and are exposed to market risks in the ordinary course of our business.
Foreign Exchange Risk
We have foreign exchange rate risk in our 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. We estimate that if the exchange rate were to change by 10% in any one country where we have our operations, the change in net income would not be material to our operations taken as a whole.
33

We may manage our exposure to transactional exposures by entering into foreign currency forward contracts for forecasted transactions and projected cash flows for foreign currencies in future periods. In 2020 and 2021, we entered into financial contracts to hedge the risk of fluctuations associated with the Chinese Yuan.
Foreign currency translation adjustments on our underlying assets and liabilities resulted in an accumulated other comprehensive loss of $1.8 million for the six months ended June 30, 2021, due to the effects of the weakening United States dollar in relation to almost all other currencies.
Interest Rate Risk
Our primary exposure to interest rate risk results from outstanding borrowings under the Credit Facility, which bears interest at variable rates. The variable interest rates on the Credit Facility fluctuate and exposes us to short-term changes in market interest rates as our interest obligation on this instrument is based on prevailing market interest rates. Interest rates fluctuate as a result of many factors, including governmental monetary and tax policies, domestic and international economic and political considerations and other factors that are beyond our control.
Item 4. Controls and Procedures.
Disclosure Controls and Procedures. As of June 30, 2021, 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. Based on this evaluation, the Company’s CEO and CFO have concluded that the Company’s disclosure controls and procedures were effective at the reasonable assurance level. 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 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.
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 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.
Changes in Internal Control over Financial Reporting. In 2016, we began the process of implementing a fully integrated ERP platform from SAP America, Inc. (“SAP”), as part of a multi-year plan to integrate and upgrade our systems and processes. As of July 31, 2021, SAP was operational, in all of North America and parts of Europe. We believe the necessary steps have been taken to monitor and maintain appropriate internal control over financial reporting during this period of change and will continue to evaluate the operating effectiveness of related key controls during subsequent periods.
As the phased implementation of this system continues, we are experiencing certain changes to our processes and procedures which, in turn, result in changes to our internal control over financial reporting. While we expect SAP to strengthen our internal financial controls by automating certain manual processes and standardizing business processes and reporting across our organization, management will continue to evaluate and monitor our internal controls as each of the affected areas evolves. For a discussion of risks related to the implementation of new systems, see Item 1A - "Risk Factors - Risks - Related to Our Intellectual Property and Information Technology - We rely on complex software systems and hosted applications to operate our business, and our business may be disrupted if we are unable to successfully/efficiently update these systems or convert to new systems." in the 2020 Form 10-K.
There were no changes in our internal control over financial reporting during the three months ended June 30, 2021 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION
Item 1. Legal Proceedings.
From time to time, the Company is involved in various legal proceedings and other matters arising in the normal course of business. Corrosion, hydrogen embrittlement, 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 currently 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 we could in the future, incur judgments, enter into settlements of claims or revise our expectations regarding the outcome of the various legal proceedings and other matters we are currently involved in, which could materially impact our financial condition, cash flows or results of operations. See “Note 13 — Commitments and Contingencies” to the accompanying unaudited interim condensed consolidated financial statements for certain potential third-party claims.
Item 1A. Risk Factors
There have been no material changes to our risk factors reported or new risk factors identified since the filing of our Annual Report on Form 10-K for the year ended December 31, 2020.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.
Our Board has authorized, as announced on December 16, 2020, the repurchase of up to $100.0 million of the Company’s common stock. For the six months ended June 30, 2021, there were no repurchases of the Company’s common stock under this authorization. As of June 30, 2021, the approximate dollar value of shares that may still be repurchased under this authorization was $100.0 million. The timing, manner, price and amount of any share repurchases will be determined by us, in our discretion, based upon the evaluation of economic and market conditions, stock price, applicable legal and regulatory requirements and other factors. This authorization is scheduled to expire on December 31, 2021. The program does not require us to repurchase any specific number of shares.
Item 3. Defaults Upon Senior Securities.
None.
