Statement of Responsibility and Management’s Report on Internal Control over Financial Reporting

Management’s Statement of Responsibility

The management of Martin Marietta Materials, Inc. (the Company or Martin Marietta) is responsible for the consolidated financial statements, the related financial information contained in this Form 10-K and the establishment and maintenance of adequate internal control over financial reporting. The consolidated balance sheets for Martin Marietta, at December 31, 2020 and 2019, and the related consolidated statements of earnings, comprehensive earnings, total equity and cash flows for each of the three years in the period ended December 31, 2020, include amounts based on estimates and judgments and have been prepared in accordance with accounting principles generally accepted in the United States applied on a consistent basis.

A system of internal control over financial reporting is designed to provide reasonable assurance, in a cost-effective manner, that assets are safeguarded, transactions are executed and recorded in accordance with management’s authorization, accountability for assets is maintained and financial statements are prepared and presented fairly in accordance with accounting principles generally accepted in the United States. Internal control systems over financial reporting have inherent limitations and may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

The Company operates in an environment that establishes an appropriate system of internal control over financial reporting and ensures that the system is maintained, assessed and monitored on a periodic basis. This internal control system includes examinations by internal audit staff and oversight by the Audit Committee of the Board of Directors.

The Company’s management recognizes its responsibility to foster a strong ethical climate. Management has issued written policy statements that document the Company’s business code of ethics. The importance of ethical behavior is regularly communicated to all employees through the distribution of the Code of Ethical Business Conduct and through ongoing education and review programs designed to create a strong commitment to ethical business practices.

The Audit Committee of the Board of Directors, which consists of four independent, nonemployee directors, meets periodically and separately with management, the independent auditors and the internal auditors to review the activities of each. The Audit Committee meets standards established by the Securities and Exchange Commission (SEC) and the New York Stock Exchange as they relate to the composition and practices of audit committees.

Management’s Report on Internal Control over Financial Reporting

The management of Martin Marietta is responsible for establishing and maintaining adequate internal control over financial reporting. Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2020. In making this assessment, management used the criteria set forth in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on management’s assessment under the 2013 framework, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2020.

The consolidated financial statements of the Company as of December 31, 2020 and 2019, and for each of the three years in the period ended December 31, 2020, and the effectiveness of the Company’s internal control over financial reporting as of December 31, 2020, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report appears on the following page.

Report of Independent Registe****red Public Accounting Firm

To the Board of Directors and Shareholders of Martin Marietta Materials, Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Martin Marietta Materials, Inc. and its subsidiaries (the “Company”) as of December 31, 2020 and 2019, and the related consolidated statements of earnings, comprehensive earnings, total equity and cash flows for each of the three years in the period ended December 31, 2020, including the related notes and schedule of valuation and qualifying accounts for each of the three years in the period ended December 31, 2020 appearing under Item 15(c) (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Change in Accounting Principle

As discussed in Note A to the consolidated financial statements, the Company changed the manner in which it accounts for leases in 2019.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and

A World-Class Organization Built for SuccessForm 10-K ♦ Page 67

Part II ♦ Item 8 – Financial Statements and Supplementary Data

that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

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

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Valuation of the Projected Benefit Obligation

As described in Note K to the consolidated financial statements, the Company’s net projected benefit obligation for all defined benefit pension plans was $1,111.9 million as of December 31, 2020. As disclosed by management, annually, as of December 31, management remeasures the defined benefit plans’ projected benefit obligation based on the present value of projected future benefit payments to all participants for services rendered to date, reflecting expected future pay increases through the participants’ expected retirement dates. The key assumptions are the discount rate, the expected long-term rate of return on pension plan assets, the mortality table and mortality improvement scale, and the rate of increase in future compensation levels. The discount rate is generally the most volatile and sensitive estimate. Accordingly, a change in this assumption has the most significant impact on the projected benefit obligation.

The principal considerations for our determination that performing procedures relating to the valuation of the projected benefit obligation is a critical audit matter are (i) the significant judgment by management to determine the projected benefit obligation; (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating the discount rate assumption; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the valuation of the projected benefit obligation, including controls over the discount rate assumption. These procedures also included, among others, testing the completeness and accuracy of underlying data used in the valuation of the projected benefit obligation and the involvement of professionals with specialized skill and knowledge to assist in (i) testing management’s process for determining the projected benefit obligation, (ii) evaluating the appropriateness of the actuarial method, and (iii) evaluating the reasonableness of the discount rate assumption.

Notes to Financial Statements

Note A: Accounting Policies

Organization. Martin Marietta is a natural resource-based building materials company. The Company supplies aggregates (crushed stone, sand and gravel) through its network of approximately 300 quarries, mines and distribution yards in 27 states, Canada and The Bahamas. In the western United States, Martin Marietta also provides cement and downstream products, namely, ready mixed concrete, asphalt and paving services, in markets where the Company also has a leading aggregates position. Specifically, the Company has two cement plants and several cement distribution facilities in Texas and Louisiana, and 120 ready mixed concrete plants and eight asphalt plants in Texas, Colorado and Wyoming. Asphalt operations and paving services are exclusively in Colorado. The Company’s heavy-side building materials are used in infrastructure, nonresidential and residential construction projects. Aggregates are also used in agricultural, utility and environmental applications and as railroad ballast. The aggregates, cement, ready mixed concrete and asphalt and paving product lines are reported collectively as the Building Materials business.

Effective July 1, 2020, the Company made organizational changes, consolidating its operational management and operating divisions in connection with the retirement of two senior executives as of the end of the second quarter. The Mid-Atlantic Division and Southeast Division were combined to form the East Division. Additionally, the Southwest Aggregates Division and the Cement and Southwest Ready Mix Division were combined to form the Southwest Division. Subsequent to these changes, the Building Materials business consists of four divisions: East, Central, Southwest and West. Each division, as well as the Magnesia Specialties business, represents an operating segment.

As of December 31, 2020, the Building Materials business contains the following reportable segments: East Group and West Group. The East Group, whose operations were previously reported in the Mid-America and Southeast Groups, consists of the East and Central Divisions and operates in Alabama, Florida, Georgia, Indiana, Iowa, Kansas, Kentucky, Maryland, Minnesota, Missouri, eastern Nebraska, North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee, Virginia, West Virginia, Nova Scotia and The Bahamas. The West Group is comprised of the Southwest and West Divisions and operates in Arkansas, Colorado, Louisiana, western Nebraska, Nevada, Oklahoma, Texas, Utah, Washington and Wyoming. In addition to these states, the Company sells to customers in New York, Delaware, New Mexico and Mississippi. The following states accounted for 71% of the Building Materials business’ 2020 total revenues: Texas, Colorado, North Carolina, Georgia and Iowa. Effective January 1, 2020, the Company moved the management of its one quarry in the state of Washington from the East Group to the West Group, resulting in an immaterial change to its reportable segments. Prior-year segment disclosures have been reclassified to conform to current-year presentation.

The Company also operates a Magnesia Specialties business, which produces magnesia-based chemical products used in industrial, agricultural and environmental applications, and dolomitic lime sold primarily to customers for steel production and land stabilization. Magnesia Specialties’ production facilities are located in Ohio and Michigan, and products are shipped to customers worldwide. During 2020, there were no changes to the Magnesia Specialties reportable segment.

Basis of Presentation and Use of Estimates. The Company’s consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States, which requires management to make certain estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities and reported amounts of revenues and expenses. Such estimates include the valuation of accounts receivable, inventories, goodwill, other intangible assets and other long-lived assets as well as assumptions used in the calculation of income tax expense, retirement and postemployment benefits, stock-based compensation, the allocation of the purchase price to the fair values of assets acquired and liabilities assumed as part of business combinations and revenue recognition for service contracts. These estimates and assumptions are based on management’s judgment. Management evaluates estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, and adjusts such estimates and assumptions when facts and circumstances dictate. Changes in credit, equity and energy markets and changes in construction activity increase the uncertainty inherent in certain estimates and assumptions. As future events and their effects, including the impact of the coronavirus (COVID-19) pandemic and the related responses, cannot be determined with precision, actual results could differ significantly from estimates. Changes in estimates, including those resulting from changes in the economic environment, are reflected in the consolidated financial statements for the period in which the change in estimate occurs. During the year ended December 31, 2019, the Company identified a prior-period error that overstated its earnings from a nonconsolidated equity affiliate. The pretax noncash adjustment was deemed immaterial to prior periods and was therefore corrected as an out-of-period expense of $15.7 million

Form 10-K ♦ 74A World-Class Organization Built for Success

Part II ♦ Item 8 – Financial Statements and Supplementary Data

that was recorded in other nonoperating expenses, consistent with the recurring classification of equity earnings from the nonconsolidated affiliate.

Basis of Consolidation. The consolidated financial statements include the accounts of the Company and its wholly-owned and majority-owned subsidiaries. Partially-owned affiliates are either consolidated or accounted for using the cost method or the equity method, depending on the level of ownership interest or the Company’s ability to exercise control over the affiliates’ operations. Intercompany balances and transactions between subsidiaries have been eliminated in consolidation.

Revenue Recognition. Total revenues include sales of products and services provided to customers, net of discounts or allowances, if any, and include freight and delivery costs billed to customers. Revenues for product sales are recognized when control of the promised good is transferred to unaffiliated customers, typically when finished products are shipped. Revenues derived from the paving business are recognized using the percentage-of-completion method under the cost-to-cost approach. Under the cost-to-cost approach, recognized contract revenue is determined by multiplying the total estimated contract revenue by the estimated percentage of completion. Contract costs are recognized as incurred. The percentage of completion is determined on a contract-by-contract basis using project costs incurred to date as a percentage of total estimated project costs. The Company believes the cost-to-cost approach is appropriate, as the use of asphalt in a paving contract is relatively consistent with the performance of the related paving services. Paving contracts, notably with governmental entities, may contain performance bonuses based on quality specifications. Given the uncertainty of meeting the criteria until the performance obligation is completed, performance bonuses are recognized as revenues when and if achieved. Performance bonuses were not material to the Company’s consolidated results of operations for the years ended December 31, 2020, 2019 and 2018. Freight revenues reflect delivery arranged by the Company using a third party on behalf of the customer and are recognized consistently with the timing of the product revenues.

Freight and Delivery Costs. Freight and delivery costs represent pass-through transportation costs incurred and paid by the Company to third-party carriers to deliver products to customers. These costs are then billed to the customers.

Cash, Cash Equivalents and Restricted Cash. Cash equivalents are comprised of highly-liquid instruments with original maturities of three months or less from the date of purchase.

As of December 31, 2020, the Company had $97.1 million of restricted cash, which was invested in an account designated for the purchase of like-kind exchange replacement assets under Section 1031 of the Internal Revenue Code (Section 1031). The Company is restricted from utilizing the cash for purposes other than the purchase of the qualified assets for 180 days from receipt of the proceeds from the sale of the exchanged property. Any unused cash at the end of the 180 days will be transferred to unrestricted accounts of the Company and can then be used for general corporate purposes. The Company did not use $47.2 million within the allowable 180-day period and transferred that amount to unrestricted cash in January 2021. The Company has until March 9, 2021 to utilize the remaining funds to purchase qualified assets under Section 1031.

In connection with Accounting Standards Update (ASU) 2016-18, Statement of Cash Flows (Topic 230), the statement of cash flows reflects cash flow changes and balances for cash, cash equivalents and restricted cash on an aggregated basis.

The following table reconciles cash, cash equivalents and restricted cash as reported on the consolidated balance sheets to the aggregated amounts presented on the consolidated statements of cash flows:

December 31 (in millions)202020192018
Cash and cash equivalents$207.3$21.0$44.9
Restricted cash97.1——
Total cash, cash equivalents and restricted cash presented in the consolidated statements of cash flows$304.4$21.0$44.9

Accounts Receivable. Accounts receivable are stated at cost. The Company does not typically charge interest on customer accounts receivable. The Company records an allowance for credit losses, which includes a provision for probable losses based on historical write-offs, adjusted for current conditions as deemed necessary, and a specific reserve for accounts deemed at risk. The allowance is the Company’s estimate for receivables as of the balance sheet date that ultimately will not be collected. Any changes in the allowance are reflected in earnings in the period in which the change occurs. The Company writes-off accounts receivable when it becomes probable, based upon customer facts and circumstances, that such amounts will not be collected.

Inventories Valuation. Finished products and in process inventories are stated at the lower of cost or net realizable value using standard costs, which approximate the first-in, first-out method. Carrying value for parts and supplies are determined by the weighted-average cost method. The Company records an allowance for finished product inventories based on an analysis of future demand and inventory on hand in excess of historical sales for a twelve-month period or an annual average for a period of up to five years. The Company also establishes an allowance for parts over five years old and supplies over a year old.

Post-production stripping costs, which represent costs of removing overburden and waste materials to access mineral deposits, are a component of inventory production costs and recognized as incurred.

Property, Plant and Equipment. Property, plant and equipment are stated at cost.

The estimated service lives for property, plant and equipment are as follows:

Class of AssetsRange of Service Lives
Buildings5 to 30 years
Machinery & Equipment2 to 20 years
Land Improvements5 to 60 years

The Company begins capitalizing quarry development costs at a point when reserves are determined to be proven or probable, economically mineable and when demand supports investment in the market. Capitalization of these costs ceases when production commences. Capitalized quarry development costs are classified as land improvements and depreciated over the life of the reserves.

The Company reviews relevant facts and circumstances to determine whether to capitalize or expense pre-production stripping costs when additional pits are developed at an existing quarry. If the additional pit operates in a separate and distinct area of the quarry, these costs are capitalized as quarry development costs and depreciated over the life of the uncovered reserves. Additionally, a separate asset retirement obligation is created for additional pits when the liability is incurred. Once a pit enters the production phase, all post-production stripping costs are charged to inventory production costs as incurred.

Mineral reserves and mineral interests acquired in connection with a business combination are valued using an income approach for the estimated life of the reserves. The Company’s aggregates reserves average approximately 90 years, based on 2020 production levels.

Depreciation is computed based on estimated service lives using the straight-line method. Depletion of mineral reserves is calculated based on proven and probable reserves using the units-of-production method on a quarry-by-quarry basis.

Property, plant and equipment are reviewed for impairment whenever facts and circumstances indicate that the carrying amount of an asset group may not be recoverable. An impairment loss is recognized if expected future undiscounted cash flows over the estimated remaining service life of the related asset group are less than the asset group’s carrying value.

Repair and Maintenance Costs. Repair and maintenance costs that do not substantially extend the life of the Company’s plant and equipment are expensed as incurred.

Leases. If the Company determines a contract is or contains a lease at inception of the agreement, the Company records right-of-use (ROU) assets, which represent the Company’s right to use an underlying leased asset, and leased liabilities, which represent the Company’s obligation to make lease payments. The ROU asset and lease liability are recorded on the consolidated balance sheet at the present value of the future lease payments over the lease term at commencement date. The Company determines the present value of lease payments based on the implicit interest rate, which may be explicitly stated in the lease, if available, or may be the Company’s estimated collateralized incremental borrowing rate based on the term of the lease. Initial ROU assets also include any lease payments made at or before commencement date and any initial direct costs incurred and are reduced by lease incentives. Certain of the Company’s leases contain renewal and/or termination options. The Company recognizes renewal or termination options as part of its ROU assets and lease liabilities when the Company has the unilateral right to renew or terminate and it is reasonably certain these options will be exercised.

Some leases require the Company to pay non-lease components, which may include taxes, maintenance, insurance and certain other expenses applicable to the leased property, and are primarily variable costs. The Company accounts for lease and non-lease components as a single amount, with the exception of railcar and fleet vehicle leases, for which the Company separately accounts for the lease and non-lease components.

Leases are evaluated and determined to be either operating leases or finance leases. The lease is a finance lease if it: transfers ownership to the underlying asset by the end of the lease term; includes a purchase option that is reasonably certain to be exercised; has a lease term for the major part of the remaining economic life of the underlying asset; has a present value of the sum of the lease payments that equals or exceeds substantially all of the fair value of the underlying asset; or is for an underlying asset that is of a specialized nature and is expected to have no alternative use to the lessor at the end of the lease term. If none of these terms exist, the lease is an operating lease.

Form 10-K ♦ 76A World-Class Organization Built for Success

Part II ♦ Item 8 – Financial Statements and Supplementary Data

Leases with an initial lease term of one year or less are not recorded on the balance sheet. Costs for these leases are expensed as incurred.

In the consolidated statements of earnings, operating lease expense, which is recognized on a straight-line basis over the lease term, and the amortization of finance lease ROU assets are included in cost of revenues or selling, general and administrative expenses. Accretion on the liabilities for finance leases is included in interest expense.

Goodwill and Other Intangible Assets. Goodwill represents the excess purchase price paid for acquired businesses over the estimated fair value of identifiable assets and liabilities. Other intangible assets represent amounts assigned principally to contractual agreements and are either amortized ratably over the useful lives to the Company or not amortized if deemed to have an indefinite useful life.

The Company’s reporting units, which represent the level at which goodwill is tested for impairment, are based on the operating segments of the Building Materials business. Goodwill is assigned to the respective reporting unit(s) based on the location of acquisitions at the time of consummation. Goodwill is tested for impairment by comparing each reporting unit’s fair value to its carrying value, which represents a Step-1 approach. However, prior to Step 1, the Company may perform a qualitative assessment and evaluate macroeconomic conditions, industry and market conditions, cost factors, overall financial performance and other business or reporting unit-specific events that contribute to the fair value of a reporting unit. If the Company concludes it is more-likely-than-not (i.e., a likelihood of more than 50%) that a reporting unit’s fair value is higher than its carrying value, the Company is not required to perform any further goodwill impairment testing for that reporting unit. Otherwise, the Company proceeds to Step 1, and if a reporting unit’s fair value exceeds its carrying value, there is no impairment. A reporting unit with a carrying value in excess of its fair value results in an impairment charge equal to the difference.

The carrying values of goodwill and other indefinite-lived intangible assets are reviewed for impairment annually, as of October 1. An interim review is performed between annual tests if facts and circumstances indicate potential impairment. The carrying value of other amortizable intangible assets is reviewed if facts and circumstances indicate potential impairment. If a review indicates the carrying value is impaired, a charge is recorded.

Retirement Plans and Postretirement Benefits. The Company sponsors defined benefit retirement plans and also provides other postretirement benefits. The Company recognizes the funded status, defined as the difference between the fair value of plan assets and the benefit obligation, of its pension plans and other postretirement benefits as an asset or liability on the consolidated balance sheets. Actuarial gains or losses that arise during the year are recognized as a component of accumulated other comprehensive earnings or loss. Those amounts are amortized over the participants’ average remaining service period and recognized as a component of net periodic benefit cost. The amount amortized is determined using a corridor approach and represents the excess over 10% of the greater of the projected benefit obligation or pension plan assets.

Insurance Reserves. The Company has insurance coverage with large deductibles for workers’ compensation, automobile liability, marine liability and general liability claims, and is also self-insured for health claims. The Company records insurance reserves based on an actuarial-determined analysis, which calculates development factors that are applied to total case reserves within the insurance programs. While the Company believes the assumptions used to calculate these liabilities are appropriate, significant differences in actual experience and/or significant changes in these assumptions may materially affect insurance costs.

Stock-Based Compensation. The Company has stock-based compensation plans for employees and its Board of Directors. The Company recognizes all forms of stock-based awards that vest as compensation expense. The compensation expense is the fair value of the awards at the measurement date and is recognized over the requisite service period. Forfeitures are recognized as they occur.

The fair value of restricted stock awards, incentive compensation stock awards and Board of Directors’ fees paid in the form of common stock are based on the closing price of the Company’s common stock on the grant dates. The fair value of performance stock awards as of the grant dates is determined using a Monte Carlo simulation methodology.

Environmental Matters. The Company records a liability for an asset retirement obligation at fair value in the period in which it is incurred. The asset retirement obligation is recorded at the acquisition date of a long-lived tangible asset if the fair value can be reasonably estimated. A corresponding amount is capitalized as part of the asset’s carrying amount. The fair value is affected by management’s assumptions regarding the scope of the work, inflation rates and asset retirement dates.

Further, the Company records an accrual for other environmental remediation liabilities in the period in which it is probable that a liability has been incurred and the appropriate amounts can be estimated reasonably. Such accruals are adjusted as further information develops or circumstances change. Generally, these costs are not discounted to their present value or offset for potential insurance or other claims or potential gains from future alternative uses for a site.

Income Taxes. Deferred income taxes, net, on the consolidated balance sheets reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, net of valuation allowances. The effect of changes in enacted tax rates on deferred income tax assets and liabilities is charged or credited to income tax expense in the period of enactment.

Uncertain Tax Positions. The Company recognizes a tax benefit when it is more-likely-than-not, based on the technical merits, that a tax position would be sustained upon examination by a taxing authority. The amount to be recognized is measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. The Company’s unrecognized tax benefits are recorded in other liabilities on the consolidated balance sheets or as an offset to the deferred tax asset for tax carryforwards where available.

The Company records interest accrued in relation to unrecognized tax benefits as income tax expense. Penalties, if incurred, are recorded as operating expenses in the consolidated statements of earnings.

Sales Taxes. Sales taxes collected from customers are recorded as liabilities until remitted to taxing authorities and therefore are not reflected in the consolidated statements of earnings.

Start-Up Costs. Noncapital start-up costs for new facilities and products are charged to operations as incurred.

Consolidated Comprehensive Earnings and Accumulated Other Comprehensive Loss. Consolidated comprehensive earnings for the Company consist of consolidated net earnings, adjustments for the funded status of pension and postretirement benefit plans, foreign currency translation adjustments and the amortization of the value of terminated forward starting interest rate swap agreements into interest expense, and are presented in the Company’s consolidated statements of comprehensive earnings.

Accumulated other comprehensive loss consists of unrecognized gains and losses related to the funded status of the pension and postretirement benefit plans and foreign currency translation, and is presented on the Company’s consolidated balance sheets.

Earnings Per Common Share. The Company computes earnings per common share (EPS) pursuant to the two-class method. The two-class method determines EPS for common stock and participating securities according to dividends or dividend equivalents and their respective participation rights in undistributed earnings. The Company paid nonforfeitable dividend equivalents during the vesting period on its restricted stock awards and incentive stock awards made prior to 2016, which results in these being considered participating securities.

The numerator for basic and diluted earnings per common share is net earnings attributable to Martin Marietta, reduced by dividends and undistributed earnings attributable to the Company’s participating securities. The denominator for basic earnings per common share is the weighted-average number of common shares outstanding during the period. Diluted earnings per common share is computed assuming that the weighted-average number of common shares is increased by the conversion, using the treasury stock method, of awards issued to employees and nonemployee members of the Company’s Board of Directors under certain stock-based compensation arrangements if the conversion is dilutive.

The following table reconciles the numerator and denominator for basic and diluted earnings per common share:

New Accounting Pronouncements

Credit Losses

Effective January 1, 2020, the Company adopted ASU 2016-13, Financial Instruments – Credit Losses (ASU 2016-13), which includes a current expected credit loss (CECL) model that requires an entity to estimate credit losses expected over the life of an exposure or pool of exposures based on historical information, current information and reasonable and supportable forecasts at the time the asset is recognized and is remeasured at each reporting period. ASU 2016-13 primarily relates to the Company’s receivables, but the scope also includes retainage and contract assets related to its paving business. The adoption of ASU 2016-13 did not have a material impact on the Company’s financial position or statement of earnings and comprehensive earnings, but the Company amended its allowance for credit losses policy for the implementation of ASU 2016-13.

Defined Benefit Plan Disclosures

Effective for the year ended December 31, 2020, the Company adopted ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (ASU 2018-14), which simplifies disclosures requirements for defined benefit plans. ASU 2018-14 requires explanations for significant gains and losses related to changes in the benefit obligation; eliminates sensitivity disclosures for a one-percent change in the assumed health care cost trend rate; and eliminates the disclosure of the estimated amounts in accumulated other comprehensive income/loss expected to be recognized in net periodic benefit costs over the next year. Disclosures in Note K have been modified on a retrospective basis for all years presented.

Leases

Effective January 1, 2019, the Company adopted ASC 842, which applies to virtually all leases, excluding mineral interest royalty agreements. ASC 842 requires the modified retrospective transition approach, applying the new standard to all leases existing at the date of initial application. It further states that an entity may use either 1) its effective date or 2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. The Company used the effective date as the date of initial application. As such, financial information and disclosures required under ASC 842 are not provided for dates and periods prior to January 1, 2019.

The lease standard provides a number of practical expedients for transition accounting. The Company elected the “package of practical expedients”, which permitted the Company to not reassess its prior conclusions about lease identification, lease classification and initial direct costs. The Company elected the practical expedients pertaining to the use of hindsight and to land easements. Applying the hindsight practical expedient resulted in longer lease terms for many leases.

The adoption of ASC 842 resulted in the recognition of ROU assets and lease liabilities of $502.5 million and $501.6 million, respectively, for operating leases and $10.9 million and $12.1 million, respectively, for finance leases. The adoption did not have a material impact on the Company’s consolidated statement of earnings or consolidated statement of cash flows.

Note B: Revenue Recognition

Performance Obligations. Performance obligations are contractual promises to transfer or provide a distinct good or service for a stated price. The Company’s product sales agreements are single-performance obligations that are satisfied at a point in time. Performance obligations within paving service agreements are satisfied over time, primarily ranging from one day to two years. For product revenues and freight revenues, customer payment terms are generally 30 days from invoice date. Customer payments for the paving operations are based on a contractual billing schedule and are due 30 days from invoice date.

Future revenues from unsatisfied performance obligations at December 31, 2020, 2019 and 2018 were $110.1 million, $136.1 million and $78.1 million, respectively, where the remaining periods to complete these obligations ranged from one month to 22 months.

Sales Taxes. The Company is deemed to be an agent when collecting sales taxes from customers. Sales taxes collected are recorded as liabilities until remitted to taxing authorities and are not reflected in the consolidated statements of earnings as revenues and expenses.

Contract Balances. Costs in excess of billings relate to the conditional right to consideration for completed contractual performance and are contract assets on the consolidated balance sheets. Costs in excess of billings are reclassified to accounts receivable when the right to consideration becomes unconditional. Billings in excess of costs relate to customers invoiced in advance of contractual performance and are contract liabilities on the consolidated balance sheets. The following table presents information about the Company’s contract balances:

Revenues recognized from the beginning balance of contract liabilities for the years ended December 31, 2020 and 2019 were $6.9 million and $6.6 million, respectively.

Retainage, which primarily relates to the paving services, represents amounts that have been billed to customers but payment withheld until final acceptance of the performance obligation by the customer. Included in Other current assets on the Company’s consolidated balance sheets, retainage was $10.6 million and $10.2 million at December 31, 2020 and 2019, respectively.

Policy Elections. When the Company arranges third-party freight to deliver products to customers, the Company has elected the delivery to be a fulfillment activity rather than a separate performance obligation. Further, the Company acts as a principal in the delivery arrangements and, as required by the revenue standard, the related revenues and costs are presented gross and are included in the consolidated statements of earnings.

On March 5, 2020, the Company issued $500.0 million aggregate principal amount of 2.500% Senior Notes due 2030 (the 2.500% Senior Notes). The 2.500% Senior Notes are carried net of original issue discount, which is being amortized by the effective interest method over the life of the issue. The 2.500% Senior Notes are redeemable prior to December 15, 2029 at their make-whole redemption price at a discount rate of the U.S. Treasury Rate plus 30 basis points, or on or after December 15, 2029 at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest to the date of redemption. The Company used the net proceeds for general corporate purposes, including the repayment of $300.0 million of Floating Rate Senior Notes at maturity in May 2020. At December 31, 2019, the Floating Rate Senior Notes due May 2020 were classified as noncurrent long-term debt on the consolidated balance sheet as the Company had the intent and ability to refinance the notes on a long-term basis.

The Company’s 4.25% Senior Notes due 2024, 7% Debentures due 2025, 3.450% Senior Notes due 2027, 3.500% Senior Notes due 2027, 2.500% Senior Notes due 2030, 6.25% Senior Notes due 2037 and 4.250% Senior Notes due 2047 (collectively, the Senior Notes) are senior unsecured obligations of the Company, ranking equal in right of payment with the Company’s existing and future unsubordinated indebtedness. Upon a change-of-control repurchase event and a resulting below-investment-grade credit rating, the Company would be required to make an offer to repurchase all outstanding Senior Notes, with the exception of the 7% Debentures due 2025, at a price in cash equal to 101% of the principal amount of the Senior Notes, plus any accrued and unpaid interest.

The Senior Notes are carried net of original issue discount, which is being amortized by the effective interest method over the life of the issue. The Senior Notes are redeemable prior to their respective maturity dates at a make-whole redemption price. The principal amount, effective interest rate and maturity date for the Senior Notes are as follows:

The Company has a credit agreement with JPMorgan Chase Bank, N.A., as Administrative Agent, Truist Bank, Deutsche Bank Securities, Inc., and Wells Fargo Bank, N.A., as Co-Syndication Agents, and the lenders party thereto (the Credit Agreement), which provides for a $700.0 million five-year senior unsecured revolving facility (the Revolving Facility). Borrowings under the Revolving Facility bear interest, at the Company’s option, at rates based upon the London Inter-bank Offered Rate (LIBOR) or a base rate, plus, for each rate, a margin determined in accordance with a ratings-based pricing grid.

Form 10-K ♦ 86A World-Class Organization Built for Success

Part II ♦ Item 8 – Financial Statements and Supplementary Data

The Credit Agreement requires the Company’s ratio of consolidated net debt-to-consolidated earnings before interest, taxes, depreciation, depletion and amortization, as defined, for the trailing-twelve months (the Ratio) to not exceed 3.50x as of the end of any fiscal quarter, provided that the Company may exclude from the Ratio debt incurred in connection with certain acquisitions during the quarter or three preceding quarters so long as the Ratio calculated without such exclusion does not exceed 3.75x. Additionally, if no amounts are outstanding under both the Revolving Facility and the trade receivable securitization facility (discussed later), consolidated debt, including debt for which the Company is a co-borrower (see Note O), shall be reduced by the Company’s unrestricted cash and cash equivalents in excess of $50.0 million, such reduction not to exceed $200.0 million, for purposes of the covenant calculation. The Company was in compliance with the Ratio at December 31, 2020.

The Revolving Facility expires on December 5, 2024, with any outstanding principal amounts, together with interest accrued thereon, due in full on that date. Available borrowings under the Revolving Facility are reduced by any outstanding letters of credit issued by the Company under the Revolving Facility. At December 31, 2020 and 2019, the Company had $2.6 million and $2.3 million, respectively, of outstanding letters of credit issued under the Revolving Facility and $697.4 million and $697.7 million, respectively, available for borrowing under the Revolving Facility. The Company paid the bank group an upfront loan commitment fee that is being amortized over the life of the Revolving Facility. The Revolving Facility includes an annual facility fee.

The Company, through a wholly-owned special-purpose subsidiary, has a $400.0 million trade receivable securitization facility (the Trade Receivable Facility). On September 23, 2020, the Company extended the maturity to September 22, 2021. The Trade Receivable Facility, with Truist Bank, Regions Bank, PNC Bank, N.A., The Bank of Tokyo-Mitsubishi UFJ, Ltd., New York Branch, and certain other lenders that may become a party to the facility from time to time, is backed by eligible trade receivables, as defined. Borrowings are limited to the lesser of the facility limit or the borrowing base, as defined. These receivables are originated by the Company and then sold or contributed to the wholly-owned special-purpose subsidiary. The Company continues to be responsible for the servicing and administration of the receivables purchased by the wholly-owned special-purpose subsidiary. Borrowings under the Trade Receivable Facility bear interest at a rate equal to asset-backed commercial paper costs of conduit lenders plus 0.85% for borrowings funded by conduit lenders and one-month LIBOR plus 1.00%, subject to change in the event that this rate no longer reflects the lender’s cost of lending, for borrowings funded by all other lenders. The Trade Receivable Facility contains a cross-default provision to the Company’s other debt agreements. At December 31, 2020, there were no borrowings outstanding under the Trade Receivable Facility and $340.0 million of borrowings outstanding at December 31, 2019.

Note I: Financial Instruments

The Company’s financial instruments include temporary cash investments, restricted cash, accounts receivable, notes receivable, accounts payable, publicly-registered long-term notes, debentures and other long-term debt.

Temporary cash investments are placed primarily in money market funds, money market demand deposit accounts or offshore time deposit accounts with financial institutions. The Company’s cash equivalents have maturities of less than three months. Due to the short maturity of these investments, they are carried on the consolidated balance sheets at cost, which approximates fair value.

Restricted cash is held in a trust account with a third-party intermediary. Due to the short-term nature of this account, the fair value of restricted cash approximates its carrying value.

A World-Class Organization Built for SuccessForm 10-K ♦ Page 87

Part II ♦ Item 8 – Financial Statements and Supplementary Data

Accounts receivable are due from a large number of customers, primarily in the construction industry, and are dispersed across wide geographic and economic regions. However, accounts receivable are more heavily concentrated in certain states, namely Texas, Colorado, North Carolina, Georgia and Iowa. The estimated fair values of accounts receivable approximate their carrying amounts.

Notes receivable are primarily promissory notes with customers and are not publicly traded. Management estimates that the fair value of notes receivable approximates its carrying amount.

Accounts payable represent amounts owed to suppliers and vendors. The estimated fair value of accounts payable approximates its carrying amount due to the short-term nature of the payables.

The carrying values and fair values of the Company’s long-term debt were $2.63 billion and $3.08 billion, respectively, at December 31, 2020 and $2.77 billion and $2.94 billion, respectively, at December 31, 2019. The estimated fair value of the Company’s publicly-registered long-term debt was estimated based on Level 2 of the fair value hierarchy using quoted market prices. The estimated fair values of other borrowings, which primarily represent variable-rate debt, approximate their carrying amounts as the interest rates reset periodically.

Note J: Income Taxes

The components of the Company’s income tax expense are as follows:

For the year ended December 31, 2018, the benefit related to the utilization of federal net operating loss (NOL) carryforwards, reflected in current tax expense, was $5.8 million. Additionally, for the year ended December 31, 2018, the Company completed the accounting for the impact of the 2017 Tax Cuts and Jobs Act and recorded a net income tax benefit of $18.9 million, primarily related to the accelerated deductions for pension funding, inventory and insurance prepayments that were claimed on the Company’s 2017 income tax returns.

For the years ended December 31, 2020, 2019 and 2018, foreign pretax earnings were $8.9 million, $15.1 million and $5.7 million, respectively.

Form 10-K ♦ 88A World-Class Organization Built for Success

Part II ♦ Item 8 – Financial Statements and Supplementary Data

The Company’s effective income tax rate varied from the statutory United States income tax rate because of the following tax differences:

years ended December 31202020192018
Statutory income tax rate21.0%21.0%21.0%
(Reduction) increase resulting from:
Effect of statutory depletion(2.8)(3.4)(3.4)

Impact from 2017 Tax Cuts and Jobs Act——(3.3)
Other items(0.6)0.31.2
Effective income tax rate18.9%18.2%18.3%

The statutory depletion deduction for all years is calculated as a percentage of sales, subject to certain limitations. Due to these limitations, the impact of changes in the sales volumes and earnings may not proportionately affect the Company’s statutory depletion deduction and the corresponding impact on the effective income tax rate.

In 2020, the Company financed third-party railroad track maintenance. In exchange, the Company received a federal income tax credit and deduction.

The Company recognized a net tax benefit from the change in tax status of a subsidiary from a partnership to a corporation in 2019, which reduced income tax expense and increased consolidated net earnings by $15.2 million, or $0.24 per diluted share.

The principal components of the Company’s deferred tax assets and liabilities are as follows:

The Company had $3.1 million and $4.1 million of domestic federal NOL carryforwards at December 31, 2020 and 2019, respectively. The Company had domestic state NOL carryforwards of $137.1 million and $161.0 million at December 31, 2020 and 2019, respectively. These carryforwards have various expiration dates through 2040. At December 31, 2020 and 2019, deferred tax assets associated with these carryforwards were $9.0 million and $10.5 million, respectively, net of the federal benefit of the state deduction, for which valuation allowances of $8.1 million and $9.0 million, respectively, were recorded. The Company also had domestic state tax credit carryforwards of $1.0 million and $1.1 million at December 31, 2020 and 2019, respectively, which have various expiration dates through 2040. At December 31, 2020 and 2019, deferred tax assets associated with these carryforwards were $0.8 million and $0.9 million, respectively, net of the federal benefit of the state deduction.

A World-Class Organization Built for SuccessForm 10-K ♦ Page 89

Part II ♦ Item 8 – Financial Statements and Supplementary Data

Deferred tax liabilities for property, plant and equipment result from accelerated depreciation methods being used for income tax purposes as compared with the straight-line method for financial reporting purposes.

Deferred tax liabilities related to goodwill and other intangibles reflect the cessation of goodwill amortization for financial reporting purposes, while amortization continues for income tax purposes.

The Company expects to permanently reinvest the earnings from its wholly-owned Canadian and Bahamian subsidiaries, and accordingly, has not provided deferred taxes on the subsidiaries’ undistributed net earnings or basis differences. The Company believes that the tax liability that would be incurred upon repatriation is immaterial at December 31, 2020.

The following table summarizes the Company’s unrecognized tax benefits, excluding interest and correlative effects of $0.2 million, $1.7 million and $0.6 million for the years ended December 31, 2020, 2019 and 2018 respectively:

years ended December 31 (in millions)202020192018

Unrecognized tax benefits at end of year$8.2$25.5$24.1
Amount that, if recognized, would favorably impact the effective tax rate$6.4$15.5$12.8

Unrecognized tax benefits are reversed as a discrete event if an examination of applicable tax returns is not initiated by a federal or state tax authority within the statute of limitations or upon effective settlement with federal or state tax authorities. For the year ended December 31, 2020, $9.7 million was reversed into income upon the statute of limitations expiration for the 2016 and all prior open tax years. Management believes its accrual for unrecognized tax benefits is sufficient to cover uncertain tax positions reviewed during audits by taxing authorities.

The Company anticipates that it is reasonably possible that its unrecognized tax benefits may decrease up to $4.4 million, excluding interest and correlative effects, during the twelve months ending December 31, 2021, due to the expiration of the statutes of limitations for the 2017 tax year.

The Company’s tax years subject to federal, state or foreign examinations are 2016 through 2020.

Note K: Retirement Plans, Postretirement and Postemployment Benefits

The Company sponsors defined benefit retirement plans that cover substantially all employees. Additionally, the Company provides other postretirement benefits for certain employees, including medical benefits for retirees and their spouses and retiree life insurance. Employees starting on or after January 1, 2002 are not eligible for postretirement welfare plans. The Company also provides certain benefits, such as disability benefits, to former or inactive employees after employment but before retirement.

The measurement date for the Company’s defined benefit plans, postretirement benefit plans and postemployment benefit plans is December 31.

Defined Benefit Retirement Plans. Retirement plan assets are invested in listed stocks, bonds, hedge funds, real estate and cash equivalents. Defined retirement benefits for salaried employees are based on each employee’s years of service and average compensation for a specified period of time before retirement. Defined retirement benefits for hourly employees are generally stated amounts for specified periods of service.

The Company sponsors a Supplemental Excess Retirement Plan (SERP) that generally provides for the payment of retirement benefits in excess of allowable Internal Revenue Code limits. The SERP generally provides for a lump-sum payment of vested benefits. When these benefit payments exceed the sum of the service and interest costs for the SERP during a year, the Company recognizes a pro rata portion of the SERP’s unrecognized actuarial loss as settlement expense.

The components of net periodic benefit cost, other than service cost, are included in the line item Other nonoperating (income) and expenses, net, in the consolidated statements of earnings. Based on the roles of the employees, service cost is included in Cost of revenues – products and services or Selling, general and administrative expenses line items in the consolidated statements of earnings.

The expected return on assets is calculated by applying an annually selected expected long-term rate of return assumption to the estimated fair value of the plan assets during the year, giving consideration to contributions and benefits paid.

participants; both tables were adjusted to reflect the experience of the Company’s participants. The Company used the MP-2020 and MP-2018 mortality improvement scale for the years 2020 and 2019, respectively.

The target allocation for 2020 and the actual pension plan asset allocation by asset class are as follows:

The Company’s investment strategy is for approximately 45% of equity securities, excluding hedge funds and real estate, to be invested in mid-sized to large capitalization U.S. funds, with the remaining invested in small capitalization, emerging markets and international funds. Debt securities, or fixed income investments, are invested in funds benchmarked to the Barclays U.S. Aggregate Bond Index.

1These investments are common collective investment trusts valued using the net asset value (NAV) unit price provided by the fund administrator. The NAV is based on the value of the underlying assets owned by the fund.

Real estate investments are stated at estimated fair value, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair values of real estate

investments generally do not reflect transaction costs that may be incurred upon disposition of the real estate investments and do not necessarily represent the prices at which the real estate investments would be sold or repaid, since market prices of real estate investments can only be determined by negotiation between a willing buyer and seller. An independent valuation consultant is employed to determine the fair value of the real estate investments. The value of hedge funds is based on the values of the sub-fund investments. In determining the fair value of each sub-fund’s investment, the hedge funds’ Board of Trustees uses the values provided by the sub-funds and any other considerations that may, in its judgment, increase or decrease such estimated value. Private infrastructure assets represent investments in a fund that is stated at fair value. For financial assets in the fund that are actively traded in organized financial markets, fair value is based on exchange-quoted market prices. For investments in the fund for which there is no quoted market price, fair value is determined by the Trustees/General Partner based on discounted expected future cash flows prepared by third-party professionals.

In 2020 and 2019, the Company made combined pension plan and SERP contributions of $88.4 million and $58.9 million, respectively. The Company currently estimates that it will contribute $82.6 million to its pension plans in 2021.

This plan, qualified under Section 401(a) of the Internal Revenue Code, is a retirement savings and investment plan for the Company’s salaried and hourly employees. Under certain provisions of the plan, the Company matches employees’ eligible contributions at established rates. The Company’s matching obligations were $17.9 million in 2020, $17.6 million in 2019 and $16.5 million in 2018.

Note L: Stock-Based Compensation

On May 19, 2016, the Company’s shareholders approved the Martin Marietta Amended and Restated Stock-Based Award Plan. The Martin Marietta Materials, Inc. Stock-Based Award Plan, as amended from time to time, along with the Amended Omnibus Securities Award Plan, originally approved in 1994 (collectively, the Plans), are still effective for awards made prior to 2017. The Company has been authorized by the Board of Directors to repurchase shares of the Company’s common stock for issuance under the stock-based award plans (see Note N).

The Company grants restricted stock awards under the Plans to a group of executive officers, key personnel and nonemployee members of the Board of Directors. The vesting of certain restricted stock awards is based on certain performance criteria over a specified period of time. The number of shares may be increased to the maximum or reduced to the minimum threshold based on the results of those criteria. In addition, certain awards are granted to individuals to encourage retention and motivate key employees. These awards generally vest if the employee is continuously employed over a specified period of time and require no payment from the employee. Awards granted to nonemployee members of the Board of Directors vest immediately.

The fair value of stock-based award grants is expensed over the vesting period. Awards to employees eligible for retirement prior to the award becoming fully vested are expensed over the period through the date that the employee first becomes eligible to retire and is no longer required to provide service to earn the award. Awards granted to nonemployee members of the Board of Directors are expensed immediately.

Additionally, an incentive compensation stock plan has been adopted under the Plans whereby certain participants may elect to use up to 50% of their annual incentive compensation to acquire units representing shares of the Company’s common stock at a 20% discount to the market value on the date of the incentive compensation award. Certain executive officers are required to participate in the incentive compensation stock plan at established minimum levels. Participants receive unrestricted shares of common stock in an amount equal to their respective units generally at the end of a 34-month period of additional employment from the date of award or at retirement beginning at age 62. All rights of ownership of the common stock convey to the participants upon the issuance of their respective shares at the end of the ownership-vesting period.

Prior to 2016, under the Plans, the Company granted options to employees to purchase its common stock at a price equal to the closing market value at the date of grant. Options become exercisable in four annual installments beginning one year after date of grant. Options granted starting in 2013 expire ten years after the grant date, while outstanding options granted prior to 2013 expire eight years after the grant date.

The following table includes summary information for stock options as of December 31, 2020:

the shares, the Company agreed to not issue any additional awards under the legacy TXI plan. The awards available for grant under the Plans at December 31, 2020 reflect no awards available under the legacy TXI plan.

In 1996, the Company adopted the Shareholder Value Achievement Plan to award shares of the Company’s common stock to key senior employees based on certain common stock performance criteria over a long-term period. Under the terms of this plan, 0.3 million shares of common stock were reserved for issuance. Through December 31, 2020, 42,025 shares have been issued under this plan. No awards have been granted under this plan since 2000.

The Company adopted and the shareholders approved the Common Stock Purchase Plan for Directors in 1996, which provides nonemployee members of the Board of Directors the election to receive all or a portion of their total fees in the form of the Company’s common stock. Beginning in 2016, members of the Board of Directors were not required to defer any of their fees in the form of the Company’s common stock. Under the terms of this plan, 0.3 million shares of common stock were reserved for issuance. Nonemployee members of the Board of Directors elected to defer portions of their fees representing 3,043, 2,756 and 3,105 shares of the Company’s common stock under this plan during 2020, 2019 and 2018, respectively.

These divisions are consolidated into two reportable segments, the East Group and the West Group, for financial reporting purposes as they meet the aggregation criteria. Additional information on reportable segment changes is provided in Note A. Prior-year reportable segment information has been reclassified to conform to the current-year presentation. The Magnesia Specialties business represents an individual operating and reportable segment. The accounting policies used for segment reporting are the same as those described in Note A.

The Chief Operating Decision Maker’s evaluation of performance and allocation of resources are based primarily on earnings from operations. Consolidated earnings from operations include total revenues less cost of revenues; selling, general and administrative expenses; acquisition-related expenses, net; other operating income, net; and excludes interest expense; other nonoperating income and expenses, net; and income tax expense. Corporate loss from operations primarily includes depreciation; expenses for corporate administrative functions; acquisition-related expenses, net; and other nonrecurring income and expenses excluded from the Company’s evaluation of segment performance and resource allocation. All long-term debt and related interest expense are held at Corporate.

Assets employed by segment include assets directly identified with those operations. Corporate assets consist primarily of cash, cash equivalents and restricted cash; property, plant and equipment for corporate operations; investments and other assets not directly identifiable with a reportable segment.
