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

The following is management’s discussion and analysis of certain significant factors that have affected our consolidated financial condition and results of operations during the periods included herein. This discussion should be read in conjunction with our historical Consolidated Financial Statements and Notes to Consolidated Financial Statements in Part II — Item 8. “Financial Statements and Supplementary Data” of this 2021 Form 10‑K. This discussion contains forward-looking statements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under Part I — Item 1A. “Risk Factors” or in other parts of this 2021 Form 10‑K. For discussion related to the changes in financial condition for the year ended December 31, 2020 compared to the year ended December 31, 2019, refer to Part II — Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources” in our 2020 Form 10‑K, which was filed with the SEC on March 4, 2021, and which is incorporated herein by reference.

Overview

Northwest Pipe Company is a leading manufacturer for water related infrastructure products. In addition to being the largest manufacturer of engineered steel water pipeline systems in North America, we manufacture high-quality precast and reinforced concrete products; water, wastewater, and stormwater equipment; steel casing pipe, bar-wrapped concrete cylinder pipe, and one of the largest offerings of pipeline system joints, fittings, and specialized components. Strategically positioned to meet growing water and wastewater infrastructure needs, we provide solution-based products for a wide range of markets under the ParkUSA, Geneva Pipe and Precast, Permalok®, and Northwest Pipe Company lines. Our diverse team is committed to quality and innovation while demonstrating our core values of accountability, commitment, and teamwork. We are headquartered in Vancouver, Washington, and have 13 manufacturing facilities across North America.

Our water infrastructure products are sold generally to installation contractors, who include our products in their bids to federal, state, and municipal agencies, privately-owned water companies, or developers for specific projects. We believe our sales are substantially driven by spending on urban growth and new water infrastructure with a recent trend towards spending on water infrastructure replacement, repair, and upgrade. Within the total range of products, our steel pipe tends to fit the larger-diameter, higher-pressure pipeline applications, while our precast concrete products mainly serve stormwater and sanitary sewer systems.

In October 2021 we acquired Park Environmental Equipment, LLC, a precast concrete and steel fabrication-based company in Texas that develops and manufactures water, wastewater, and environmental solutions. In January 2020, we acquired Geneva Pipe and Precast Company (fka Geneva Pipe Company, Inc.), a concrete pipe and precast concrete products manufacturer based in Utah. Effective in the fourth quarter of 2021, as a result of the acquisition of ParkUSA, we revised our historical one segment position and identified the new operating segments, Engineered Steel Pressure Pipe (SPP) and Precast Infrastructure and Engineered Systems (Precast), to align with changes made in our internal management structure and our reporting structure of financial information used to assess performance and allocate resources. For detailed descriptions of these segments, see the “Our Segments” discussion in Part I — Item 1. “Business” of this 2021 Form 10‑K.

Our Current Economic Environment

We operate our business with a long-term time horizon. Projects are often planned for many years in advance, and are sometimes part of 50‑year build-out plans. Long-term demand for water infrastructure projects in the United States appears strong. However, in the near term, we expect that strained governmental and water agency budgets and financing along with increased manufacturing capacity from competition could impact the business. Additionally, we have started to experience effects of a current labor shortage at certain manufacturing facilities, for which we are mitigating the impact through the use of overtime and third-party outsourcing as warranted. It is possible that a prolonged shortage of qualified, available workers could result in a further increase in labor costs that could impact our business.

Fluctuating steel costs will also be a factor, as the ability to adjust our selling prices as steel costs fluctuate depends on market conditions. Purchased steel represents a substantial portion of our cost of sales of steel pipe products, and changes in our selling prices often correlate directly to changes in steel costs. Recently, steel markets have been extremely volatile, and the cost of steel introduced into the manufacturing process increased 67% in 2021 compared to 2020. Due to production and delivery lead times for steel, these costs in 2021 were not always indicative of the current market prices.

Impact of the COVID‑19 Pandemic on Our Business

While the COVID‑19 pandemic did cause indirect financial impacts associated with project bidding, execution, and delivery delays during the year ended December 31, 2021, we are unable to predict the ultimate impact that the COVID‑19 pandemic may have on our business, future results of operations, financial position, or cash flows. For additional details, refer to the information set forth under the caption “Impact of the COVID‑19 Pandemic on Our Business” in Part I — Item 1. “Business” and discussions in Part I — Item 1A. “Risk Factors” of this 2021 Form 10‑K.

Results of Operations

The following table sets forth, for the periods indicated, certain financial information regarding costs and expenses expressed in dollars (in thousands) and as a percentage of total net sales.

Year Ended December 31, 2021 Compared to Year Ended December 31, 2020

Net sales. Net sales increased 16.6% to $333.3 million in 2021 compared to $285.9 million in 2020.

SPP net sales increased 7.5% to $259.8 million in 2021 compared to $241.7 million in 2020 driven by a 15% increase in selling price per ton due to increased materials costs and changes in product mix, partially offset by a 6% decrease in tons produced resulting from changes in project timing. Bidding activity, backlog, and production levels may vary significantly from period to period affecting sales volumes.

24

Table of Contents

Precast net sales increased 66.2% to $73.5 million in 2021 compared to $44.2 million in 2020 primarily due to the ParkUSA operations acquired in October 2021, which contributed $18.0 million in net sales during the fourth quarter of 2021, as well as a 26% increase in net sales at the Geneva operations acquired in January 2020 due to an 18% increase in shipments and a 6% increase in selling prices.

Gross profit. Gross profit decreased 12.4% to $44.3 million (13.3% of net sales) in 2021 compared to $50.5 million (17.7% of net sales) in 2020.

SPP gross profit decreased 29.4% to $31.3 million (12.0% of SPP net sales) in 2021 compared to $44.3 million (18.3% of SPP net sales) in 2020 due to the combination of changes in product mix and pressure on project pricing. Additionally, as a result of the fire at our Saginaw facility in April 2019, $1.4 million of business interruption insurance recovery (net of incremental production costs) was recorded in 2020.

Precast gross profit increased 108.4% to $13.0 million (17.7% of Precast net sales) in 2021 compared to $6.2 million (14.1% of Precast net sales) in 2020 due to contributions from the ParkUSA operations acquired in October 2021, as well as higher prices and production volume at the Geneva operations. Precast gross profit in 2021 was reduced by $2.1 million in higher acquisition-related fair value inventory charges.

Selling, general, and administrative expense. Selling, general, and administrative expense increased 13.1% to $28.2 million (8.4% of net sales) in 2021 compared to $25.0 million (8.8% of net sales) in 2020. The increase in selling, general, and administrative expense was primarily due to $1.8 million in higher compensation-related expense, $0.6 million in higher acquisition-related transaction costs, and $0.8 million in higher depreciation and amortization expense, all primarily due to the acquisition of ParkUSA in October 2021.

Other income. In 2020, we recognized gains on insurance proceeds of $1.0 million for property damage resulting from the fire at our Saginaw facility.

Income taxes. Income tax expense was $3.6 million in 2021 (an effective income tax rate of 24.0%) compared to $6.6 million in 2020 (an effective income tax rate of 25.7%). The effective income tax rate for 2021 was primarily impacted by estimated changes in our valuation allowance. The effective income tax rate for 2020 was primarily impacted by costs associated with the acquisition of Geneva that were non-deductible for tax purposes. The effective income tax rate can change significantly depending on the relationship of permanent income tax deductions and tax credits to estimated pre-tax income or loss and the changes in valuation allowances. Accordingly, the comparison of effective income tax rates between periods is not meaningful in all situations.

Year Ended December 31, 2020 Compared to Year Ended December 31, 2019

Net sales. Net sales increased 2.4% to $285.9 million in 2020 compared to $279.3 million in 2019.

SPP net sales decreased 13.5% to $241.7 million in 2020 compared to $279.3 million in 2019 driven by a 28% decrease in tons produced resulting from changes in project timing, partially offset by a 20% increase in selling price per ton due to a change in product mix. Additionally, the pandemic-related shut-down of our San Luis Río Colorado, Mexico facility negatively impacted our sales in the second quarter of 2020. Bidding activity, backlog, and production levels may vary significantly from period to period affecting sales volumes.

Precast net sales increased to $44.2 million in 2020 compared to $0 in 2019 due to the contribution from the Geneva operations acquired in January 2020.

Gross profit. Gross profit increased 7.1% to $50.5 million (17.7% of net sales) in 2020 compared to $47.2 million (16.9% of net sales) in 2019.

SPP gross profit decreased 6.1% to $44.3 million (18.3% of SPP net sales) in 2020 compared to $47.2 million (16.9% of SPP net sales) in 2019 due to lower production volume, partially offset by improved product pricing. Additionally, as a result of the fire at our Saginaw facility in April 2019, $1.4 million of business interruption insurance recovery (net of incremental production costs) was recorded in 2020, compared to $1.6 million of incremental production costs (net of business interruption insurance recovery) in 2019.

Precast gross profit increased to $6.2 million (14.1% of Precast net sales) in 2020 compared to $0 in 2019 due to the contribution from the Geneva operations acquired in January 2020.

Selling, general, and administrative expense. Selling, general, and administrative expense increased 34.9% to $25.0 million (8.8% of net sales) in 2020 compared to $18.5 million (6.6% of net sales) in 2019. The increase in selling, general, and administrative expense was primarily due to the addition of Geneva, including $2.7 million in higher compensation-related expense, $2.0 million in higher acquisition-related transaction costs, and $0.9 million in higher intangible amortization expense. In addition, we incurred $0.8 million in higher administrative expense.

Other income. In 2020 and 2019, we recognized gains on insurance proceeds of $1.0 million and $1.6 million, respectively, for property damage resulting from the fire at our Saginaw facility. In August 2019, we received $2.3 million of proceeds related to a favorable legal settlement involving certain pipe produced at our former Houston, Texas and Bossier City, Louisiana facilities.

Income taxes. Income tax expense was $6.6 million in 2020 (an effective income tax rate of 25.7%) compared to $4.7 million in 2019 (an effective income tax rate of 14.5%). The effective income tax rate for 2020 was primarily impacted by costs associated with the acquisition of Geneva that were non-deductible for tax purposes. The effective income tax rate for 2019 was primarily impacted by the estimated changes in our valuation allowance. The effective income tax rate can change significantly depending on the relationship of permanent income tax deductions and tax credits to estimated pre-tax income or loss and the changes in valuation allowances. Accordingly, the comparison of effective income tax rates between periods is not meaningful in all situations.

Liquidity and Capital Resources

Sources and Uses of Cash

Our principal sources of liquidity generally include operating cash flows and the Amended Credit Agreement. From time to time our long-term capital needs may be met through the issuance of long-term debt or additional equity. Our principal uses of liquidity generally include capital expenditures, working capital, organic growth initiatives, acquisitions, and debt service. Information regarding our cash flows for the years ended December 31, 2021, 2020, and 2019 are presented in our Consolidated Statements of Cash Flows contained in Part II — Item 8. “Financial Statements and Supplementary Data” of this 2021 Form 10‑K, and are further discussed below.

As we cannot predict the duration or scope of the COVID‑19 pandemic and its impact on our customers and suppliers, the potential negative financial impact to our results cannot be reasonably estimated, but could be material. We are actively managing the business to maintain cash flow and believe we have liquidity to meet our anticipated funding requirements and other near-term obligations.

As of December 31, 2021, our working capital (current assets minus current liabilities) was $164.1 million compared to $146.1 million as of December 31, 2020. Cash and cash equivalents totaled $3.0 million and $37.9 million as of December 31, 2021 and 2020, respectively. The decrease is primarily attributable to the repayment of long-term debt and changes in working capital in 2021.

Fluctuations in SPP working capital accounts result from timing differences between production, shipment, invoicing, and collection, as well as changes in levels of production and costs of materials. We typically have a relatively large investment in working capital, as we generally pay for materials, labor, and other production costs in the initial stages of a project, while payments from our customers are generally received after finished product is delivered. A portion of our revenues are recognized over time as the manufacturing process progresses; therefore, cash receipts typically occur subsequent to when revenue is recognized and the elapsed time between when revenue is recorded and when cash is received can be significant. As such, our payment cycle is a significantly shorter interval than our collection cycle, although the effect of this difference in the cycles may vary by project, and from period to period.

As of December 31, 2021, we had $86.8 million of outstanding revolving loan borrowings, $98.4 million of operating lease liabilities, and $2.2 million of finance lease liabilities. For future maturities of these obligations, see Notes 7 and 8 of the Notes to Consolidated Financial Statements in Part II — Item 8. “Financial Statements and Supplementary Data” of this 2021 Form 10‑K.

Due to the uncertainty with respect to the timing of future cash flows associated with our approximately $4.4 million in unrecognized tax benefits as of December 31, 2021, we are unable to make reasonably reliable estimates of the period of cash settlement with the respective taxing authorities. For further information, see Note 15 of the Notes to Consolidated Financial Statements in Part II — Item 8. “Financial Statements and Supplementary Data” of this 2021 Form 10‑K.

Net Cash Provided by (Used in) Operating Activities

Net cash provided by (used in) operating activities was $(5.8) million in 2021 compared to $56.1 million in 2020. Net income, adjusted for non-cash items, provided $28.7 million of operating cash flow in 2021 compared to $40.3 million of operating cash flow in 2020. The net change in working capital provided (used) $(34.5) million of operating cash flow in 2021 compared to $15.8 million of operating cash flow in 2020.

Net Cash Used in Investing Activities

Net cash used in investing activities was $100.2 million in 2021 compared to $61.4 million in 2020. Acquisitions of businesses, net of cash acquired, were $87.2 million in 2021 compared to $48.7 million in 2020. Capital expenditures were $13.3 million in 2021 compared to $14.0 million in 2020, which was primarily for standard capital replacement. We currently expect capital expenditures in 2022 to be approximately $26 million to $30 million, which includes an approximately $13 million of additional investment in a new reinforced concrete pipe mill and the remainder primarily for standard capital replacement.

Net Cash Provided by Financing Activities

Net cash provided by financing activities was $71.0 million in 2021 compared to $12.3 million in 2020. Net borrowings on the line of credit were $86.8 million in 2021 compared to $0 in 2020. Net borrowings (repayments) on long-term debt were $(13.8) million in 2021 compared to $13.8 million in 2020.

We anticipate that our existing cash and cash equivalents, cash flows expected to be generated by operations, and additional borrowing capacity under the Amended Credit Agreement will be adequate to fund our working capital, debt service, and capital expenditure requirements for at least the next twelve months. To the extent necessary, we may also satisfy capital requirements through additional bank borrowings, senior notes, term notes, subordinated debt, and finance and operating leases, if such resources are available on satisfactory terms. We have from time to time evaluated and continue to evaluate opportunities for acquisitions and expansion. Any such transactions, if consummated, may necessitate additional bank borrowings or other sources of funding. As previously discussed, we acquired ParkUSA in October 2021 which was funded primarily by borrowings on the line of credit.

On November 3, 2020, our registration statement on Form S‑3 (Registration No. 333‑249637) covering the potential future sale of up to $150 million of our equity and/or debt securities or combinations thereof, was declared effective by the SEC. This registration statement, which replaced the registration statement on Form S‑3 that expired on September 15, 2020, provides another potential source of capital, in addition to other alternatives already in place. We cannot be certain that funding will be available on favorable terms or available at all. To the extent that we raise additional funds by issuing equity securities, our shareholders may experience significant dilution. As of the date of this 2021 Form 10‑K, we have not yet sold any securities under this registration statement, nor do we have an obligation to do so. Please refer to the factors discussed in Part I — Item 1A. “Risk Factors” of this 2021 Form 10‑K.

Credit Agreement

The Amended Credit Agreement provides for a revolving loan, swingline loan, and letters of credit in the aggregate amount of up to $125 million (“Revolver Commitment”). The Amended Credit Agreement will expire, and all obligations outstanding will mature, on June 30, 2024. We may prepay outstanding amounts in our discretion without penalty at any time, subject to applicable notice requirements. As of December 31, 2021 under the Amended Credit Agreement, we had $86.8 million of outstanding revolving loan borrowings, $1.6 million of outstanding letters of credit, and additional borrowing capacity of approximately $37 million. Based on our business plan and forecasts of operations, we expect to have sufficient credit available to support our operations for at least the next twelve months.

Revolving loans under the Amended Credit Agreement bear interest at rates related to, at our option and subject to the provisions of the Amended Credit Agreement including certain LIBOR transition provisions, either: (i) Base Rate (as defined in the Amended Credit Agreement) plus the Applicable Margin; (ii) LIBOR plus the Applicable Margin; or (iii) the daily one month LIBOR plus the Applicable Margin. The “Applicable Margin” is 1.75% to 2.25%, depending on our Senior Leverage Ratio (as defined in the Amended Credit Agreement). Interest on outstanding revolving loans is payable quarterly. Swingline loans under the Amended Credit Agreement bear interest at the Base Rate plus the Applicable Margin. The Amended Credit Agreement requires the payment of a commitment fee of between 0.30% and 0.40%, based on the amount by which the Revolver Commitment exceeds the average daily balance of outstanding borrowings (as defined in the Amended Credit Agreement). Such fee is payable quarterly in arrears. We are also obligated to pay additional fees customary for credit facilities of this size and type.

27

Table of Contents

The letters of credit outstanding as of December 31, 2021 relate to workers’ compensation insurance. Based on the nature of these arrangements and our historical experience, we do not expect to make any material payments under these arrangements.

The Amended Credit Agreement contains customary representations and warranties, as well as customary affirmative and negative covenants, events of default, and indemnification provisions in favor of the Lenders. The negative covenants include restrictions regarding the incurrence of liens and indebtedness, annual capital expenditures, certain investments, acquisitions, and dispositions, and other matters, all subject to certain exceptions. The Amended Credit Agreement requires us to regularly provide financial information to Wells Fargo and to maintain a consolidated senior leverage ratio no greater than 2.50 to 1.00 (subject to certain exceptions) and a minimum consolidated earnings before interest, taxes, depreciation, and amortization (as defined in the Amended Credit Agreement) of at least $31.5 million for the four consecutive fiscal quarters most recently ended. Pursuant to the Amended Credit Agreement, we have also agreed that we will not sell, assign, or otherwise dispose or encumber, any of our owned real property. The occurrence of an event of default could result in the acceleration of the obligations under the Amended Credit Agreement. We were in compliance with our financial covenants as of December 31, 2021. Based on our business plan and forecasts of operations, we believe we will remain in compliance with our financial covenants for the next twelve months.

Our obligations under the Amended Credit Agreement are secured by a senior security interest in substantially all of our and our subsidiaries’ assets.

Recent Accounting Pronouncements

For a description of recent accounting pronouncements affecting our company, including the dates of adoption and estimated effects on financial position, results of operations, and cash flows, see Note 2 of the Notes to Consolidated Financial Statements in Part II — Item 8. “Financial Statements and Supplementary Data” of this 2021 Form 10‑K.

Critical Accounting Estimates

Management Estimates

The preparation of our Consolidated Financial Statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses, and disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. On an ongoing basis, we evaluate all of our estimates including those related to revenue recognition, business combinations, goodwill, inventories, property and equipment, including depreciation and valuation, share-based compensation, income taxes, allowance for doubtful accounts, and litigation and other contingencies. Actual results may differ from these estimates under different assumptions or conditions. We believe the following critical accounting policies and related judgments and estimates affect the preparation of our Consolidated Financial Statements.

Revenue Recognition

SPP revenue for water infrastructure steel pipe products is recognized over time as the manufacturing process progresses because of our right to payment for work performed to date plus a reasonable profit on cancellations for unique products that have no alternative use to us. Revenue is measured by the costs incurred to date relative to the estimated total direct costs to fulfill each contract (cost-to-cost method). Contract costs include all material, labor, and other direct costs incurred in satisfying performance obligations. The cost of steel material is recognized as a contract cost when the steel is introduced into the manufacturing process. Estimated total costs of each contract are reviewed on a monthly basis by project management and operations personnel for all active projects. All cost revisions that result in a material change in gross profit are reviewed by senior management personnel. Significant judgment is required in estimating total costs and measuring the progress of project completion, as well as whether a loss is expected to be incurred on the contract. We use certain assumptions and develop estimates based on a number of factors, including the degree of required product customization, our historical experience, the project plans, and an assessment of the risks and uncertainties inherent in the contract related to implementation delays or performance issues that may or may not be within our control. Changes in job performance, job conditions, and estimated profitability, including those arising from contract change orders, contract penalty provisions, foreign currency exchange rate movements, changes in raw materials costs, and final contract settlements may result in revisions to estimates of revenue, costs, and income, and are recognized in the period in which the revisions are determined. Provisions for losses on uncompleted contracts are estimated by comparing total estimated contract revenue to the total estimated contract costs and a loss is recognized during the period in which it becomes probable and can be reasonably estimated.

28

Table of Contents

Precast revenue for water infrastructure concrete pipe and precast concrete products is recognized at the time control is transferred to customers, in an amount that reflects the consideration we expect to be entitled to in exchange for the products. All variable consideration that may affect the total transaction price, including contractual discounts, returns, and credits, is included in net sales. Estimates for variable consideration are based on historical experience, anticipated performance, and management’s judgment. Our contracts do not contain significant financing.

We do not recognize revenue on a contract until the contract has approval and commitment from both parties, the contract rights and payment terms can be identified, the contract has commercial substance, and its collectability is probable.

Business Combinations

Business combinations are accounted for under the acquisition method which requires identifiable assets acquired and liabilities assumed 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 amount by which the net fair value of assets acquired and liabilities assumed exceeds the fair value of consideration transferred as the purchase price is recorded as a bargain purchase gain. Acquisition-related costs are expensed as incurred.

Accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed in order to allocate purchase price consideration properly. These assumptions and estimates include a market participant’s use of the asset and the appropriate discount rates for a market participant. Our estimates are based on historical experience, information obtained from the management of the acquired companies and, when appropriate, include assistance from independent third-party appraisal firms. Our significant assumptions and estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, the appropriate weighted-average cost of capital, and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable. In addition, unanticipated events and circumstances may occur which may affect the accuracy or validity of such estimates. As a result, during the measurement period, which may be up to one year from the acquisition date, we may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill or bargain purchase gain.

Goodwill

Goodwill is reviewed for impairment annually as of December 31, or whenever events occur or circumstances change that indicate goodwill may be impaired. Goodwill is tested for impairment at the reporting unit level. A reporting unit is an operating segment or one level below an operating segment (also known as a component).

In testing goodwill for impairment, we have the option to perform a qualitative assessment to determine whether the existence of events or circumstances indicate that it is more-likely-than-not (more than 50%) that the fair value of a reporting unit is less than its carrying amount. When performing a qualitative assessment, we evaluate factors such as industry and market conditions, cost factors, overall financial performance, and other relevant entity specific events and changes. In the evaluation, we look at the long-term prospects for the reporting unit and recognize that current performance may not be the best indicator of future prospects or value, which requires management judgment.

If the qualitative assessment indicates that it is more-likely-than-not that the fair value of the reporting unit is less than its carrying amount, or if we choose not to perform the qualitative assessment, then a quantitative assessment is performed to determine the reporting unit’s fair value. The fair value calculation uses a combination of income and market approaches. The income approach is based upon projected future after-tax cash flows discounted to present value using factors that consider the timing and risk associated with the future after-tax cash flows. The market approach is based upon historical and/or forward-looking measures using multiples of revenue or earnings before interest, tax, depreciation, and amortization. We utilize a weighted average of the income and market approaches. If the reporting unit’s carrying value exceeds its fair value, then an impairment loss is recognized for the amount of the excess of the carrying amount over the reporting unit’s fair value, not to exceed the total amount of goodwill allocated to the reporting unit.

Inventories

Inventories are stated at the lower of cost and net realizable value. Determining net realizable value of inventories involves judgments and assumptions, including projecting selling prices and cost of sales. To estimate net realizable value, we review recent sales and gross profit history, existing customer orders, current contract prices, industry supply and demand, forecasted steel prices, replacement costs, seasonal factors, general economic trends, and other information, as applicable. If future market conditions are less favorable than those projected by us, inventory write-downs may be required. The cost of raw material inventories of steel is either on a specific identification basis or on an average cost basis. The cost of materially all other raw material inventories, as well as work-in-process and supplies, is on an average cost basis. The cost of finished goods uses the first-in, first-out method of accounting.

Property and Equipment and Intangible Assets

Property and equipment are recorded at cost, and are depreciated using either the units of production method or the straight-line method depending on the classification of the asset. Depreciation expense calculated under the units of production method may be less than, equal to, or greater than depreciation expense calculated under the straight-line method. We evaluate historical and projected units of production at each facility to reassess the units of production expected on an annual basis.

Intangible assets consist primarily of customer relationships, trade names and trademarks, patents, and backlog recorded as the result of acquisition activity. Intangible assets are amortized using the straight-line method over estimated useful lives.

We assess impairment of property and equipment and intangible assets whenever changes in circumstances indicate that the carrying values of the asset or asset group(s) may not be recoverable. The recoverable value of a long-lived asset group is determined by estimating future undiscounted cash flows using assumptions about our expected future operating performance. Estimates of future cash flows used in the recoverability test incorporate our own assumptions about the use of the asset group and shall consider all available evidence. Our estimates of undiscounted cash flows may differ from actual cash flow due to, among other things, technological changes, economic conditions, or changes to our business operations. If we determine the carrying value of the property and equipment and intangible assets will not be recoverable, we calculate and record an impairment loss.

Share-based Compensation

We recognize the compensation cost of employee and director services received in exchange for awards of equity instruments based on the grant date estimated fair value of the awards. We estimate the fair value of restricted stock units and performance share awards using the value of our stock on the date of grant. Share-based compensation cost is recognized over the period during which the employee or director is required to provide service in exchange for the award and, as forfeitures occur, the associated compensation cost recognized to date is reversed. For awards with performance-based payout conditions, we recognize compensation cost based on the probability of achieving the performance conditions, with changes in expectations recognized as an adjustment to earnings in the period of change. Any recognized compensation cost is reversed if the conditions are ultimately not met.

Income Taxes

Income taxes are recorded using an asset and liability approach that requires the recognition of deferred income tax assets and liabilities for the expected future tax consequences of events that have been recognized in our Consolidated Financial Statements or income tax returns. Valuation allowances are established when necessary to reduce deferred income tax assets to the amount expected to be realized. The determination of our provision for income taxes requires significant judgment, the use of estimates, and the interpretation and application of complex tax laws. Our provision for income taxes primarily reflects a combination of income earned and taxed in the various United States federal, state, local, and to a lesser extent, foreign jurisdictions. Jurisdictional tax law changes, increases or decreases in permanent differences between book and tax items, accruals or adjustments of accruals for unrecognized income tax benefits or valuation allowances, and our change in the mix of earnings from these taxing jurisdictions all affect the overall effective income tax rate.

We record income tax reserves for federal, state, local, and international exposures relating to periods subject to audit. The development of reserves for these exposures requires judgments about tax issues, potential outcomes and timing, and is a subjective estimate. We assess our income tax positions and record income tax benefits for all years subject to examination based upon management’s evaluation of the facts, circumstances, and information available at the reporting dates. For those income tax positions where it is more-likely-than-not that an income tax benefit will be sustained, we have recorded the largest amount of income tax benefit with a greater than 50% likelihood of being realized upon settlement with a tax authority that has full knowledge of all relevant information. For those income tax positions where it is not more-likely-than-not that an income tax benefit will be sustained, no income tax benefit has been recognized in the Consolidated Financial Statements.

Allowance for Doubtful Accounts

We maintain allowances for estimated losses resulting from the inability of our customers to make required payments or from contract disputes. The amounts of such allowances are based on historical experience and management’s judgment. The extension and revision of credit is determined by obtaining credit rating reports or financial information on the customer. An allowance is recorded based on a variety of factors, including our historical collection experience and our historical product quality claims. At least monthly, we review past due balances to identify the reasons for non-payment. We will write down or write off a receivable account once the account is deemed uncollectible for reasons such as customer quality claims, a contract dispute, deterioration in the customer’s financial position, a bankruptcy filing, or other events. If the customer’s financial conditions were to deteriorate resulting in their inability to make payments, or if contract disputes were to escalate, additional allowances may need to be recorded which would result in additional expenses being recorded for the period in which such determination was made.
