Simpson Manufacturing Co., Inc., through Simpson Strong-Tie Company Inc. and its other subsidiaries (collectively, the “Company”), focuses on designing, manufacturing, and marketing systems and products to make buildings and structures safe and secure. 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 U.S., Canada, Europe and Pacific Rim. A significant portion of the Company’s business is dependent on economic activity within the North America segment. The Company's business is also dependent on the availability of steel, its primary raw material.

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. The Company 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.

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 December 31, 2021 and 2020, the value of these investments were $26.4 million and $45.4 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.

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.

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash in banks, short-term investments in money market funds and trade accounts receivable. The Company maintains its cash in demand deposit and money market accounts held in 17 banks, and at times these cash and investments may be in excess of amounts insured by the Federal Deposit Insurance Corporation (FDIC). However, we have not experienced any losses on these accounts.

The Company applies net realizable value and makes estimates for obsolescence to the gross value of the inventory. Estimated net realizable value is 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 the 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 and has consistently applied this methodology. When impairments are established, a new cost basis of the inventory is created. An unexpected change in market demand, building codes or buyer preferences could reduce the rate of inventory turnover and require the recognition of more obsolete inventory.

The Company provides product warranties for specific product lines and records estimated 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 its consolidated results of operations, cash flows or financial position.

The Company accounts for investments and ownership interests under equity method accounting when it has the ability to exercise significant influence, but does not have a controlling financial interest. The Company records its interest in the net earnings of its equity method investees, along with adjustments for unrealized profits or losses within earnings or loss from equity interests in the consolidated statements of operations. The investment is reviewed for impairment whenever factors indicate that its carrying amount might not be recoverable and the decrease in value, if any, is recognized in the period the impairment occurs in the consolidated statement of operations.

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 December 31, 2021.

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.

Business combinations are accounted for under the acquisition method in accordance with ASC 805, Business Combinations. The acquisition method requires identifiable assets acquired and liabilities assumed and any noncontrolling interest in the business acquired be recognized and measured at fair value on the acquisition date, which is the date that the acquirer obtains control of the acquired business. The amount by which the fair value of consideration transferred as the purchase price exceeds the net fair value of assets acquired and liabilities assumed is recorded as goodwill.

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, internal costs and external consulting fees. Capitalized software projects are amortized over the estimated useful lives of the software.

estimated useful life of three to ten 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. Purchased intangible assets with finite useful lives are amortized using the straight-line method over the estimated useful lives of the assets. The weighted-average amortization period for all amortizable intangibles on a combined basis is 8.0 years.

The Company’s Board of Directors has the authority to issue 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 of Directors. Accordingly, the Board of Directors 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.

Subject to the rights of holders of any preferred stock that may be issued in the future, holders of common stock are entitled to receive dividends, if any, as may be declared from time to time by the Board of Directors out of legally available funds, and in the event of liquidation, dissolution or winding-up of the Company, to share ratably in all assets available for distribution. The holders of common stock have no preemptive or conversion rights. Subject to the rights of any preferred stock that may be issued in the future, the holders of common stock are entitled to one vote per share on any matter submitted to a vote of the stockholders. A director in an uncontested election 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 of Directors, 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 common stock.

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, changes in unamortized pension adjustments and changes in the fair value of derivative instruments classified as cash flow hedge instruments, all of which are recorded directly in accumulated other comprehensive income within stockholders’ equity.

The local currency is the functional currency for all of the Company’s operations in Europe, Canada, Asia, Australia and New Zealand. 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 presented below operating income.

Generally, the Company's revenue contract with a customer exists when (1) the goods are shipped, services are rendered, and the related invoice is generated, (2) the duration of the contract does not extend beyond the promised goods or services already transferred and (3) 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. Our shipping terms provide the primary indicator of the transfer of control. The Company's general shipping terms are Incoterm C.P.T. (F.O.B. shipping point), where the title, and risk and rewards of ownership transfer at the point when the products are no longer on the Company's premises. Other Incoterms are allowed as exceptions depending on the product or service being sold and the nature of the sale. 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 would 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.

Cost of sales includes material, labor, factory and tooling overhead, shipping, and freight costs. Major components of these expenses are steel and other materials, 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.

Product research and development costs, which are included in operating expenses and are charged against income as incurred, were $12.3 million, $10.1 million and $10.9 million in 2021, 2020 and 2019, respectively. Product research and development expenses include all related personnel costs including salary, benefits, retirement, stock-based compensation costs, as well as computer and software costs, professional fees, supplies, tools and maintenance costs. In 2021, 2020 and 2019, the Company incurred software development expenses related to its ongoing expansion into the plated truss market and some of the software development costs were capitalized. See "Note 8 — Property, Plant and Equipment." 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.

The Company has operating and finance leases for certain facilities, equipment, autos and data centers. As an accounting policy for short-term leases, the Company elected to not recognize a right-of-use asset ("ROU 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 a straight-line basis over the full lease term.

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 the end of each reporting period with changes in

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. This method gives consideration to the future tax consequences of the deferred income tax items and immediately recognizes changes in income tax laws in the year of enactment.

In March 2020, the Financial Accounting Standards Board 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. This 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 that some United States Dollar LIBOR tenors (overnight, 1 month, 3 month, and 12 month) will continue to be published until June 30, 2023. The Company does not expect a material impact to its consolidated operating results, financial position or cash flow from the transition from LIBOR to alternative reference interest rates, but the Company will continue to monitor the impact of the transition until it is completed.
