ITEM 1. BUSINESS

General

Tutor Perini Corporation, formerly known as Perini Corporation (“Perini”), was incorporated in 1918 as a successor to businesses that had been engaged in providing construction services since 1894. Tutor Perini Corporation (together with its consolidated subsidiaries, “Tutor Perini,” the “Company,” “we,” “us,” and “our,” unless the context indicates otherwise) is a leading construction company, based on revenue as ranked by Engineering News-Record (“ENR”), offering diversified general contracting, construction management and design-build services to private customers and public agencies throughout the world. Our corporate headquarters are in Los Angeles (Sylmar), California, and we have various other principal offices throughout the United States and its territories (see Item 2. Properties for a listing of our major facilities). Our common stock is listed on the New York Stock Exchange under the symbol “TPC.” We are incorporated in the Commonwealth of Massachusetts.

We have established a strong reputation within our markets for executing large, complex projects on time and within budget while adhering to strict quality control measures. We offer general contracting, pre-construction planning and comprehensive project management services, including the planning and scheduling of the manpower, equipment, materials and subcontractors required for a project. We also offer self-performed construction services including site work; concrete forming and placement; steel erection; electrical, mechanical, plumbing, heating, ventilation and air conditioning (HVAC), and fire protection. During ~~2018,~~2019, we performed work on approximately ~~1,400~~1,300 construction projects.

In ~~2018,~~ 2019, ENR ranked Tutor Perini as the ~~tenth~~12^th largest domestic contractor. We are recognized as one of the leading civil contractors in the United States, as evidenced by our performance on several of the country’s largest mass-transit and transportation projects, such as Newark Liberty International Airport Terminal One (“Newark Airport Terminal One”), the East Side Access project in New York City, the California High-Speed Rail System, the Alaskan Way Viaduct Replacement (SR 99) project in Seattle, major portions of the Red Line and Purple Line segments of the Los Angeles subway system, and the San Francisco Central Subway extension to Chinatown. We are also recognized as one of the leading building contractors in the United States, as evidenced by our performance on several of the country’s largest building development projects, including CityCenter and the Cosmopolitan Resort and Casino in Las Vegas, and Hudson Yards in New York City.

~~Since~~As a result of the 2008 merger between our predecessor companies, Tutor-Saliba Corporation (“Tutor-Saliba”) and Perini, ~~Corporation,~~and the subsequent acquisitions that we made in 2010 and 2011, we have experienced ~~significant~~ growth supported by our increased size, scale, bonding capacity, access to broader geographic regions, expanded management capabilities, complementary assets and particular expertise in large, complex projects. In 2010 and 2011, we expanded vertically and geographically through the strategic acquisitions of seven companies with demonstrated success in their respective markets. These acquisitions further strengthened our geographic presence in our Building and Civil segments and also significantly increased our specialty contracting capabilities.

Our acquisitions have enabled us to provide customers with a vertically integrated service offering. This vertical integration is a unique capability and competitive advantage that allows us to self-perform a greater amount of work than our competitors. Our vertical integration increases our competitiveness in bidding and our efficiency in managing and executing large, complex projects. It also provides us with significant cross-selling opportunities across a broad geographic footprint.

Business Segment Overview

Our business is conducted through three segments: Civil, Building and Specialty Contractors.

Civil Segment

Our Civil segment specializes in public works construction and the replacement and reconstruction of infrastructure across most of the major geographic regions of the United States. Our civil contracting services include construction and rehabilitation of highways, bridges, tunnels, mass-transit systems, military defense facilities, and water management and wastewater treatment facilities.

The Civil segment is comprised of the Company’s legacy heavy civil construction operations (civil operations of our predecessors, Tutor-Saliba, its subsidiary Black Construction, and ~~Perini Corporation)~~Perini), as well as our acquired companies, Frontier-Kemper, Lunda Construction and Becho. The Company’s legacy heavy civil units operate primarily on the West and East Coasts of the United States and are engaged in a variety of large mass-transit, ~~transportation,~~tunneling, bridge and highway projects.Black Construction is the largest contractor in Guam and provides a variety of heavy, civil, building, mechanical and electrical construction services throughout the Western Pacific region and in other strategic military locations. Frontier-Kemper is a heavy civil contractor engaged in the construction of tunnels for highways, railroads, subways and rapid transit systems; the construction of shafts and other facilities for water supply, wastewater transport and hydroelectric projects; and the development and equipping of mines with innovative hoisting, elevator and vertical conveyance systems. Lunda Construction is a heavy civil contractor specializing in the construction, rehabilitation and maintenance of bridges, railroads and other civil structures throughout the United States. Becho is engaged in drilling, foundation and excavation support for shoring, bridges, piers, roads and highway projects, primarily in the southwestern United States. We believe that the Company has benefitted from these acquisitions by an expanded geographic presence, enhanced civil construction capabilities and the addition of experienced management with proven, successful track records.

Our Civil segment’s customers primarily award contracts through one of two methods: the traditional public “competitive bid” method, in which price is the major determining factor, or through a request for proposal, where contracts are awarded based on a combination of technical qualifications, proposed project team, schedule, past performance on similar projects and price.

Traditionally, our Civil segment’s customers require each contractor to pre-qualify for construction business by meeting criteria that include technical capabilities and financial strength. Our financial strength and outstanding record of performance on challenging civil works projects often enable us to pre-qualify for projects in situations where smaller, less diversified contractors are unable to meet the qualification requirements. We believe this is a competitive advantage that makes us an attractive partner on the largest, most complex infrastructure projects and on prestigious design-build, ~~DBOM (design-build-operate-maintain)~~design-build-operate-maintain and ~~P3 (public-private partnership)~~public-private partnership projects.

In its ~~2018~~2019 rankings, ENR ranked us as the nation’s ~~second~~third largest contractor in the transportation market and ~~third~~fifth largest domestic heavy contractor.

We believe the Civil segment provides us with significant opportunities for growth due to the age and condition of existing infrastructure coupled with large government funding sources dedicated to the replacement and reconstruction of aging U.S. infrastructure. In addition, infrastructure improvement programs frequently enjoy popular, bipartisan support from the public and elected officials. Funding for major civil infrastructure projects is typically provided through a combination of one or more of the following: local, regional, state and federal loans and grants; other direct allocations sourced through tax revenue; bonds; user fees; and, for certain projects, private capital.

We have been active in civil construction since 1894 and believe we have a particular expertise in large, complex civil construction projects. We have completed, or are currently working on, some of the most significant civil construction projects in the United States. For example, we are currently working on Newark Airport Terminal One, ~~various portions of~~ the East Side Access project in New York City, the first phase of the California High-Speed Rail project, the Purple Line Segments 2 and 3 expansion projects in Los Angeles, ~~and~~ the San Francisco Central Subway extension to ~~Chinatown.~~Chinatown and the Minneapolis Southwest Light Rail Transit project. We have also completed major projects such as the Alaskan Way Viaduct Replacement (SR 99) in Seattle; the platform over the eastern rail yard at Hudson Yards in New York City; the rehabilitation of the Verrazano-Narrows Bridge in New York; and multiple runway reconstruction projects, including the John F. Kennedy International Airport in New York, Los Angeles International Airport and Fort Lauderdale-Hollywood International Airport.

Building Segment

Our Building segment has significant experience providing services to a number of specialized building markets for private and public works customers, including hospitality and gaming, transportation, health care, commercial offices, government facilities, sports and entertainment, education, correctional facilities, biotech, pharmaceutical, industrial and high-tech. We believe the success of the Building segment results from our proven ability to manage and perform large, complex projects with aggressive fast-track schedules, elaborate designs, and advanced mechanical, electrical and life safety systems, while providing accurate budgeting and strict quality

control. Although price is a key competitive factor, we believe our strong reputation, long-standing customer relationships and significant level of repeat and referral business have enabled us to achieve a leading position in the marketplace.

~~Table of Contents~~

In its ~~2018~~2019 rankings, ENR ranked us as the 1117^th largest domestic building contractor. We are a recognized leader in the hospitality and gaming market, specializing in the construction of high-end resorts and casinos. We work with hotel operators, Native American tribal councils, developers and architectural firms to provide diversified construction services to meet the challenges of new construction and renovation of hotel and resort properties. We believe that our reputation for completing projects on time is a significant competitive advantage in this market, as any delay in project completion could result in significant loss of revenue for the customer.

The Building segment is comprised of several operating units that provide general contracting, design-build, preconstruction and construction services in various regions of the United States. Tutor Perini Building ~~Corp.~~Corporation focuses on large, complex building projects nationwide, including significant projects in the hospitality and gaming, commercial office, education, government facilities, and multi-unit residential markets. Rudolph and Sletten focuses on large, complex projects in California in the health care, commercial office, technology, industrial, education, and government facilities markets. Roy Anderson Corp. provides general contracting services, including major disaster response support, to public and private customers primarily throughout the southeastern United States. Perini Management Services provides diversified construction and design-build services internationally to U.S. government agencies, as well as to surety companies and multi-national corporations.

We have recently completed, or are currently working on, large private and public building projects across a wide array of building end markets, including commercial offices, multi-unit residential, health care, hospitality and gaming, transportation, education and entertainment. Specific projects include Newark Airport Terminal One in Newark, New Jersey; ~~two~~three large corporate office buildings in northern California for ~~different~~distinct confidential technology customers; a commercial office tower at 10 Hudson Yards and a multi-unit residential tower at 15 Hudson Yards in New York City; the ~~Washington~~El Camino Hospital ~~expansion~~Integrated Medical Office Building in ~~Fremont,~~El Camino, California; Kaiser Hospital Buildings in San Leandro, Redwood City and Roseville, California; the ~~Graton Rancheria~~Choctaw Casino and Resort ~~and Casino~~ in ~~Rohnert Park, California;~~Durant, Oklahoma; the Pechanga Resort and Casino expansion in Temecula, California; the ~~Maryland Live! Casino expansion~~O Street Government Office Building in ~~Hanover, Maryland; Kaiser Hospital Buildings in San Leandro and Redwood City,~~Sacramento, California; and courthouses in San Bernardino and San Diego, California and Broward County, Florida. As a result of our reputation and track record, we were previously awarded and completed contracts for several marquee ~~projects in the~~ hospitality and gaming ~~market,~~projects in Las Vegas, including ~~the Resorts World New York Casino in Jamaica, New York, as well as~~ CityCenter, the Cosmopolitan Resort and Casino and the Wynn Encore ~~Hotel, Trump International Hotel and Tower, Paris Las Vegas and Planet Hollywood in Las Vegas.~~Hotel. These projects span a wide array of building end markets and illustrate our Building segment’s résumé of successfully completed large-scale public and private projects.

Specialty Contractors Segment

Our Specialty Contractors segment specializes in electrical, mechanical, plumbing, HVAC, fire protection systems and pneumatically placed concrete for a full range of civil and building construction projects in the industrial, commercial, hospitality and gaming, and mass-transit end markets. This segment provides unique strengths and capabilities that position us as a full-service contractor with greater control over project bids and costs, scheduled work, project delivery and risk management. The majority of work performed by the Specialty Contractors segment is contracted directly with state and local municipal agencies, real estate developers, school districts and other commercial and industrial customers. A ~~growing~~significantportion of its work is expected to be performed for our Civil and Building segments in future years.

The Specialty Contractors segment is comprised of several operating units that provide unique services in various regions of the United States. Five Star Electric has established itself as an industry leader and is one of the largest electrical contractors in New York City. Five Star Electric provides construction services in the electrical sector, including power, lighting, fire alarm, security, telecommunications, low voltage and wireless systems to both the public and private sectors. These services are provided across end markets that include multi-unit residential, hotels, commercial offices, industrial, mass transit, education, retail, sports and entertainment, health care and water treatment. Fisk Electric (“Fisk”) covers many of the major commercial, transportation and industrial electrical construction markets in California and the southern United States, with the ability to cover other attractive markets nationwide. Fisk’s expertise is in technology design and the development of electrical and technology systems for major projects spanning a broad variety of project types, including commercial office buildings, sports arenas, hospitals, research laboratories, hotels and casinos, convention centers, manufacturing plants, refineries, and water and wastewater treatment facilities. WDF, Nagelbush and Desert Mechanical each provide mechanical, plumbing, HVAC and fire protection services to a range of customers in a wide variety of markets, including transportation, commercial/industrial, schools and universities and residential. WDF is one of the largest mechanical contractors servicing the New York City metropolitan region. Nagelbush operates primarily in Florida and Desert Mechanical operates primarily in the western United States. Superior Gunite specializes in pneumatically placed structural concrete utilized in infrastructure projects nationwide, such as bridges, dams, tunnels and retaining walls.

The Specialty Contractors segment has also supported, or is currently supporting, several large projects in our Civil and Building segments, including the Alaskan Way Viaduct Replacement (SR 99) project in Seattle; the San Francisco Central Subway extension to Chinatown; the Purple Line ~~Segment~~Segments 2 and 3 expansion ~~project~~projects in Los Angeles; Newark Airport Terminal One in Newark, New Jersey; McCarran International Airport Terminal 3 in Las Vegas; and several marquee ~~projects in the~~ hospitality and gaming ~~market,~~projects in Las Vegas, including CityCenter, the Cosmopolitan Resort and Casino, and the Wynn Encore ~~Hotel in Las Vegas.~~Hotel.

Backlog

Backlog in our industry is a measure of the total value of work that is remaining to be performed on projects that have been awarded. We include a construction project in our backlog when a contract is awarded or when we have otherwise received written definitive notice that the project has been awarded to us and there are no remaining major uncertainties that the project will proceed (e.g., adequate funding is in place). As a result, we believe our backlog is firm, and although cancellations or scope adjustments may occur, historically they have not been material. We estimate that approximately $4$5 billion, or ~~45%~~44%, of our backlog as of December 31, ~~2018~~2019 will be recognized as revenue in ~~2019.~~2020. Our backlog by segment, end market and customer type is presented in the following tables:

Competition

While the construction markets include numerous competitors, especially for small to mid-sized projects, much of the work that we target is for larger, more complex projects where there are typically fewer active market participants due to the greater capabilities and resources required to perform the work. In addition to domestic competitors, we have seen certain foreign competitors attempting to grow their presence in the United States over the past several years, particularly through the pursuit of large civil projects. ~~More recently,~~In recent years, however, ~~the number~~we have observed a diminished presence from some of these foreign competitors ~~appears to be diminishing~~in the bidding for ~~many~~several of the larger U.S. ~~projects.~~project opportunities. We believe price, experience, reputation, responsiveness, customer relationships, project completion track record, schedule control, risk management and quality of work are key factors customers consider when awarding contracts.

In our Civil segment, we compete principally with large civil construction firms, including (alphabetically) Dragados USA; Fluor Corporation; Granite Construction; Kiewit Corporation; Skanska USA; Traylor Bros., Inc.; and The Walsh Group. In our Building segment, we compete with a variety of national and regional contractors, including (alphabetically) AECOM (through its acquisitions of Tishman Construction and Hunt Construction Group); Balfour Beatty Construction; Clark Construction Group; DPR Construction; Gilbane, Inc.; Hensel Phelps Construction Co.; McCarthy Building Companies, Inc.; Skanska USA; Suffolk Construction; and Turner Construction Company. In our Specialty Contractors segment, we compete principally with various regional and local electrical, mechanical and plumbing subcontractors.

Construction Costs

If prices for materials, labor or equipment increase excessively, provisions in certain types of contracts often shift all or a major portion of any adverse impact to the customer. In our fixed price contracts, we attempt to insulate ourselves from the unfavorable effects of inflation, when possible, by incorporating escalating wage and price assumptions into our construction cost estimates, by

obtaining firm fixed price quotes from major subcontractors and material suppliers, and by entering into purchase commitments for materials early in the project schedule. Construction and other materials used in our construction activities are generally available locally from multiple sources and have been in adequate supply during recent years. Labor resources for our domestic projects are largely obtained through various labor unions. We have not experienced significant labor shortages in recent years, nor do we expect to in the near future, although a significant, rapid growth in our backlog may lead to situations in which labor resources become constrained. We employ expatriate and local labor in selected overseas areas.

Environmental Matters

Our properties and operations are subject to federal, state and municipal laws and regulations relating to the protection of the environment, including requirements for water discharges; air emissions; the use, management and disposal of solid or hazardous materials or wastes; and the cleanup of contamination. In certain circumstances, we may also be required to hire subcontractors to dispose of hazardous materials encountered on a project in accordance with a plan approved in advance by the owner. We continually evaluate our compliance with all applicable environmental laws and regulations, and believe that we are in substantial compliance with those laws and regulations. However, future requirements or amendments to current laws or regulations imposing more stringent requirements could require us to incur additional costs to maintain or achieve compliance.

In addition, some environmental laws, such as the U.S. federal “Superfund” law and similar state statutes, can impose liability for the entire cost of cleanup of contaminated sites upon any of the current or former owners or operators or upon parties who generated waste at, or sent waste to, these sites, regardless of who owned the site at the time of the release or the lawfulness of the original disposal activity. Contaminants have been detected at some of the sites that we own and where we have worked as a contractor in the past, and we have incurred costs for the investigation and remediation of hazardous substances. We believe that our liabilities for these sites are not material, either individually or in the aggregate. We have pollution liability insurance coverage for such matters, and if applicable, we seek indemnification from customers to cover the risks associated with environmental remediation.

Insurance and Bonding

All of our properties and equipment, as well as those of our joint ventures, are covered by insurance in amounts that we believe are consistent with our risk of loss and industry practice. Our wholly owned subsidiary, PCR Insurance Company, issues policies for default insurance for our subcontractors, auto liability, general liability and workers’ compensation insurance, allowing us to centralize our claims and risk management functions to reduce our insurance-related costs.

As a normal part of the construction business, we are often required to provide various types of surety bonds as an additional level of security for our performance. We also require many of our higher-risk subcontractors to provide surety bonds as security for payment of subcontractors and suppliers and to guarantee their performance. As an alternative to traditional surety bonds, we also have purchased subcontractor default insurance for certain construction projects to insure against the risk of subcontractor default.

Employees

The number of our employees varies based on the number of active projects, the type and magnitude of those projects, as well as our position within the lifecycle of those projects. Our total number of employees as of December 31, ~~2018~~2019 was approximately ~~8,200.~~9,100.

We are signatory to numerous local and regional collective bargaining agreements, both directly and through trade associations, as a union contractor. These agreements cover all necessary union crafts and are subject to various renewal dates. Estimated amounts for wage escalation related to the expiration of union contracts are included in our bids on various projects; accordingly, the expiration of any union contract in the next year is not expected to have any material impact on us. During the past several years, we have not experienced any significant work stoppages caused by our union employees.

ITEM 1A. RISK FACTORS

We are subject to a number of known and unknown risks and uncertainties that could have a material adverse effect on our operations. Set forth below, and elsewhere in this report, are descriptions of the risks and uncertainties that could cause our actual results to differ materially from the results contemplated by the forward-looking statements contained in this report and could have a material adverse effect on our financial condition, results of operations and cash flows.

If we are unable to accurately estimate contract risks, revenue or costs, the timing of new awards, or the pace of project execution, we may incur a loss or achieve lower than anticipated profit.

Accounting for contract-related revenue and costs requires management to make significant estimates and assumptions that may change significantly throughout the project lifecycle, which could result in a material impact to our consolidated financial statements. In addition, cost overruns, including unanticipated cost increases on fixed price and guaranteed maximum price contracts, may result in lower profits or losses.Changes in laws, policies or regulations, including tariffs and taxes, could impact the prices for materials or equipment. Further, our results of operations can fluctuate quarterly and annually depending on when new awards occur and the commencement and progress of work on projects already awarded.

We are ~~subject to~~involved in a significant number of legal proceedings which, if determined adversely to us, could adversely affect our financial results and/or cash flows, harm our reputation and/or preclude us from bidding on future ~~projects and/or have a material effect on us.~~projects. We also may invest significant working capital on projects while legal proceedings are being settled.

We are involved in various lawsuits, including the legal proceedings described under Note 8 of the Notes to Consolidated Financial Statements. Litigation is inherently uncertain, and it is not possible to accurately predict what the final outcome will be of any legal proceeding. We must make certain assumptions and rely on estimates, which are inherently subject to risks and uncertainties, regarding potential outcomes of legal proceedings in order to determine an appropriate contingent liability and charge to income. Any result that is materially different ~~than~~from our expectations and estimates could have a material adverse effect on our financial condition, results of operations and cash flows. This may include requiring us to record an expense or reduce revenue that we previously recorded, based on our expectations or estimates, requiring us to pay damages or reducing cash collections that we had expected to receive. For example, on December 13, 2019, we received an adverse jury verdict in the case related to the construction of the Alaskan Way Viaduct Replacement Project (“SR 99”) by a joint venture for which the Company holds a 45% share as a minority partner. As a result of the unexpected adverse jury verdict, we recorded in a pre-tax charge of $166.8 million in 2019. Refer to the Alaskan Way Viaduct Matter in Note 8 of the Notes to Consolidated Financial Statements for further discussion. In addition, any adverse judgments could harm our reputation and preclude us from bidding on future projects.

We may bring claims against project owners for additional cost exceeding the contract price or for amounts not included in the original contract price. When these types of events occur and unresolved claims are pending, we may invest significant working capital in projects to cover cost overruns pending the resolution of the relevant claims. A failure to promptly recover on these types of claims could have a material effect on our liquidity and financial results.

Our contracts require us to perform extra, or change order, work which can result in disputes or claims and adversely affect our working capital, profits and cash flows.

Our contracts generally require us to perform extra, or change order, work as directed by the customer even if the customer has not agreed in advance on the scope and/or price of the work to be performed. This process may result in disputes or claims over whether the work performed is beyond the scope of work directed by the customer and/or exceeds the price the customer is willing to pay for the work performed. To the extent we do not recover our costs for this work or there are delays in the recovery of these costs, our working capital, profits and cash flows could be adversely impacted.

Our actual results could differ from the assumptions and estimates used to prepare our financial statements.

In preparing our financial statements, we are required under generally accepted accounting principles in the United States (“GAAP”) to make estimates and assumptions as of the date of the financial statements. These estimates and assumptions affect the reported values of assets, liabilities, revenue and expenses, and the disclosure of contingent assets and liabilities. Areas requiring significant estimates by our management include, but are not limited to:

• recognition of contract revenue, costs, profits or losses in applying the principles of revenue accounting;

• recognition of revenue related to project incentives or awards we expect to receive;

• recognition of recoveries under contract change orders or claims;

• estimated amounts for expected project losses, warranty costs, contract closeout or other costs;

• collectability of billed and unbilled accounts receivable;

Table of Contents

• asset valuations;

• income tax provisions and related valuation allowances;

• determination of expense and potential liabilities under pension and other post-retirement benefit programs; and

• accruals for other estimated liabilities, including litigation and insurance revenue/reserves.

~~Table of Contents~~

Our actual business and financial results could differ from our estimates of such results, which could have a material negative impact on our financial condition and reported results of operations.

~~A significant slowdown or decline in economic conditions could adversely affect our operations.~~

Any significant decline in economic conditions in any of the markets we serve or uncertainty regarding the economic outlook, could result in a decline in demand for infrastructure projects and commercial building developments. In addition, any instability in the financial and credit markets could negatively impact our customers’ ability to pay us on a timely basis, or at all, for work on projects already under construction, could cause our customers to delay or cancel construction projects in our backlog or could create difficulties for customers to obtain adequate financing to fund new construction projects. Such consequences could have an adverse impact on our future operating results. Lastly, we are more susceptible to adverse economic conditions in New York and California, as a significant portion of our operations are concentrated in those states.

~~We may not fully realize the revenue value reported in our backlog due to cancellations or reductions in scope.~~

As of December 31, 2018, our backlog of uncompleted construction work was approximately $9.3 billion. The revenue projected in our backlog may not be fully realized and, in some cases, if realized, may not result in profits or may be less profitable than expected. The cancellation or reduction in scope of significant projects included in our backlog could have a material adverse effect on our financial condition, results of operations and cash flows.

~~Competition for new project awards is intense, and our failure to compete effectively could reduce our market share and profits.~~

New project awards are determined through either a competitive bid basis or on a negotiated basis. Projects may be awarded based solely upon price, but often take into account other factors, such as technical qualifications, proposed project team, schedule and past performance on similar projects. Within our industry, we compete with many international, regional and local construction firms. Some of these competitors have achieved greater market penetration than we have in the markets in which we compete, and some have greater resources than we do. If we are unable to compete successfully in such markets, our relative market share and profits could be reduced.

The construction services industry is highly schedule driven, and our failure to meet the schedule requirements of our contracts could adversely affect our reputation and/or expose us to financial liability.

Many of our contracts are subject to specific completion schedule requirements. Any failure to meet contractual schedule requirements could subject us to liquidated damages, liability for our customer’s actual cost arising out of our delay and damage to our reputation.

In connection with mergers and acquisitions, we have recorded goodwill and other intangible assets that could become impaired and adversely affect our operating results. Assessing whether impairment has occurred requires us to make significant judgments and assumptions about the future, which are inherently subject to risks and uncertainties, and if actual events turn out to be materially less favorable than the judgments we make and the assumptions we use, we may be required to record impairment charges in the future.

We had $635.4 million of goodwill and indefinite-lived intangible assets recorded on our Consolidated Balance Sheet as of December 31, 2018. We assess these assets for impairment annually, or more often if required. Our assessments involve a number of estimates and assumptions that are inherently subjective, require significant judgment and involve highly uncertain matters that are subject to change. The use of different assumptions or estimates could materially affect the determination as to whether or not an impairment has occurred. In addition, if future events are less favorable than what we assumed or estimated in our impairment analysis, we may be required to record an impairment charge, which could have a material impact on our consolidated financial statements.

We require substantial personnel, including construction and project managers and specialty subcontractor resources to execute and perform our contracts in backlog. The successful execution of our business strategies is also dependent upon our ability to attract and retain our key officers, as well as adequately plan for their succession.

Our ability to execute and perform on our contracts in backlog depends in large part upon our ability to hire and retain highly skilled personnel, including project and construction management and trade labor resources, such as carpenters, masons and other skilled workers. In the event we are unable to attract, hire and retain the requisite personnel and subcontractors necessary to execute and perform our backlog, we may experience delays in completing projects in accordance with project schedules or an increase in expected costs, both of which could have a material adverse effect on our financial results, our reputation and our relationships. In addition, if we lack the personnel and specialty subcontractors necessary to perform on our current contract backlog, we may find it necessary to curtail our pursuit of new projects. A significant, rapid growth in our backlog may lead to situations in which labor resources become constrained.

~~Table of Contents~~

The execution of our business strategies also substantially depends on our ability to retain several key members of our management. Losing any of these individuals could adversely affect our business. The majority of these key individuals are not bound by employment agreements. Volatility or lack of positive performance in our stock price may adversely affect our ability to retain key individuals to whom we have provided share-based compensation. Additionally, because a substantial portion of our key officers' compensation is placed "at risk" and linked to the performance of our business, when our operating results are negatively impacted, we are at greater risk of employee turnover. If we lose our key officers and do not have qualified successors in place, our operating results would likely be harmed.

A significant slowdown or decline in economic conditions could adversely affect our operations.

We have a substantial amount of indebtedness which could adversely affect our financial position and prevent us from fulfilling our obligations under our debt agreements.

We currently have, and expect to continue to have, a substantial amount of indebtedness. As of December 31, ~~2018, we had~~2019, our total debt ~~of $761.5 million.~~was $834.5 million, with $124.1 million classified as current debt. If we are unable to meet the terms of the financial covenants or fail to comply with any of the other restrictions contained in the agreements governing our indebtedness, an event of default could occur, causing the debt related to such agreements to become immediately due. If such acceleration occurs, we may not be able to repay such indebtedness as required. Since indebtedness under our credit agreement entered into on April 20, 2017 (the “2017 Credit ~~Facility~~Facility”) with SunTrust Bank, now known as Truist Bank, as Administrative Agent, Swing Line Lender and L/C Issuer and a syndicate of other lenders is secured by substantially all of our assets, acceleration of this debt could result in foreclosure of those assets and a negative impact on our operations. In addition, a failure to meet the terms of our 2017 Credit Facility could result in a reduction of future borrowing capacity under the 2017 Credit Facility, causing a loss of liquidity. A loss of liquidity could adversely impact our ability to execute projects in our backlog, obtain new projects, engage subcontractors, and attract and retain key employees. Lastly, the 2017 Credit Facility includes a spring-forward provision whereby the facility will mature on December 17, 2020 if the 2.875% Convertible Senior Notes due June 15, 2021 (the “Convertible Notes”) remain outstanding at that time. While we do not have call rights that allow us to unilaterally redeem the Convertible Notes, we intend to repurchase or exchange the Convertible Notes and/or modify or replace

Inclement weather conditions, such as significant storms and unusual temperatures, can impact our ability ~~of state~~to perform work. Adverse weather conditions can cause delays and ~~local governments to raise capital~~increases in ~~the municipal bond market.~~project costs, resulting in variability in our revenue and profitability.

Our participation in construction joint ventures exposes us to liability and/or harm to our reputation for failures by our partners.

As part of our business, we enter into joint venture arrangements typically to jointly bid on and execute particular projects, thereby reducing our risk profile while enhancing the execution capability and financial reward of project teams. Success on these joint projects depends in large part on whether our joint venture partners satisfy their contractual obligations. Generally, we and our joint venture partners are jointly and severally liable for all liabilities and obligations of our joint ventures. If a joint venture partner fails to perform or is financially unable to bear its portion of required capital contributions or other obligations, including liabilities stemming from lawsuits, we could be required to make additional investments, provide additional services or pay more than our proportionate share of a liability to make up for our partner’s shortfall. Further, if we are unable to adequately address our partner’s performance issues, the customer may terminate the project, which could result in legal liability to us, harm our reputation, reduce our profit on a project or, in some cases, result in a loss.

We may not fully realize the revenue value reported in our backlog due to cancellations or reductions in scope.

As of December 31, 2019, our backlog of uncompleted construction work was approximately $11.2 billion. The revenue projected in our backlog may not be fully realized and, in some cases, if realized, may not result in profits or may be less profitable than expected. The cancellation or reduction in scope of significant projects included in our backlog could have a material adverse effect on our financial condition, results of operations and cash flows.

The level of federal, state and local government spending for infrastructure and other public projects could adversely affect the number of projects available to us in the future.

Competition for new project awards is intense, and our failure to compete effectively could reduce our market share and profits.

We had $255.5 million of goodwill and indefinite-lived intangible assets recorded on our Consolidated Balance Sheet as of December 31, 2019. We assess these assets for impairment annually, or more often if required. Our assessments involve a number of estimates

Table of Contents

and assumptions that are inherently subjective, require significant judgment and involve highly uncertain matters that are subject to change. The use of different assumptions or estimates could materially affect the determination as to whether or not an impairment has occurred. In addition, if future events are less favorable than what we assumed or estimated in our impairment analysis, we may be required to record an impairment charge, which could have a material impact on our consolidated financial statements.

Systems and information technology interruption and breaches in data security could adversely impact our ability to operate and negatively impact our operating results.

We rely on computer, information and communication technology and other related systems, some of which are hosted by third party providers, for various business processes and activities, including project management, accounting, financial reporting and business development. These systems may be subject to interruptions or damage by a variety of factors including, but not limited to, cyber-attacks, natural disasters, power loss, telecommunications failures, acts of war, computer viruses, obsolescence and physical damage. Such interruptions could result in a loss of critical data, a delay in operations or an unintentional disclosure of client confidential or personally identifiable information, any of which could have a material impact to us and our consolidated financial statements.

In addition, various privacy and security laws require us to protect sensitive and confidential information from disclosure. We dedicate considerable attention and resources to the safeguarding of our information technology systems. Our systems may, nevertheless, continue to be at risk for cyber-attacks. Consequently, we may need to engage significant resources in the future to remediate the impact of, or further mitigate the risk of, such an attack. Any successful cyber-attack could result in the criminal, or otherwise

~~Table of Contents~~

illegitimate use of, confidential data, including our data or third-party data for which we have the responsibility for safekeeping. Additionally, such an attack could adversely affect our operations, reputation and financial results.

~~Weather can significantly affect our revenue and profitability.~~

Inclement weather conditions, such as significant storms and unusual temperatures, can impact our ability to perform work. Adverse weather conditions can cause delays and increases in project costs, resulting in variability in our revenue and profitability.

We are subject to ~~a number of~~ risks ~~as a U.S. government contractor, which could harm our reputation, result in fines or penalties against us and/or adversely impact our financial condition.~~

~~Failure to comply with laws and regulations~~ related to government contracts and related procurement regulations.

Our contracts with U.S. federal, as well as state, local and foreign, government entities are subject to various procurement regulations and other requirements relating to their formation, administration and performance. We are subject to audits and investigations relating to our government contracts, and any violations could result in various civil and criminal penalties and administrative sanctions, including termination of contract, ~~termination,~~refunding or suspending of payments, forfeiture of profits, payment of fines and suspension or debarment from ~~contracting with the U.S.~~future government ~~civil fines and criminal prosecution, any of which could adversely affect our operations, reputation and financial results.~~

~~Conversion of our outstanding Convertible Notes could dilute ownership interests of existing stockholders and could adversely affect the market price of our common stock.~~

Based on the terms of the indenture for our 2.875% Convertible Senior Notes due June 15, 2021 (the “Convertible Notes”), we may redeem the Convertible Notes in cash, shares of our common stock or a combination of the two. As a result, a conversion of some or all of the Convertible Notes may dilute the ownership interests of existing stockholders. Any sales in the public market of our common stock issuable upon such conversion of the Convertible Notes could cause the price of our common stock to decline.business. In addition, some of these contracts provide for termination by the ~~existence of the Convertible Notes may encourage short selling by market participants because a conversion of the Convertible Notes could depress the price of our common stock.~~government at any time, without cause.

We may need to include the potential dilutive impact of our Convertible Notes in our diluted earnings per share calculation.

We currently intend to pay the principal amount of our Convertible Notes in cash; therefore, we have not included the potential dilutive effect of our Convertible Notes in our diluted earnings per share calculations. If, however, there is a change in future circumstances as a result of a decline in our projected cash flow, available cash/liquidity or other reasons, we may conclude at such time that it will be preferable to use shares to satisfy the Convertible Notes. Such a change in our intentions would result in the inclusion of the potential dilutive impact of the Convertible Notes in our diluted earnings per share calculation, which would result in a decrease in our diluted earnings per share.

Our international operations expose us to economic, political and other risks, as well as uncertainty related to U.S. Government funding, which could adversely affect our revenue and earnings. In addition, we could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act and similar worldwide anti-bribery laws.

For the year ended December 31, ~~2018,~~2019, we derived ~~$274.5~~$377.1 million of revenue from our work on projects located outside of the United States. Our international operations expose us to risks inherent in doing business in certain hostile regions outside the United States, including political risks; risks of loss due to acts of war; unstable economic, financial and market conditions; potential incompatibility with foreign subcontractors and vendors; foreign currency controls and fluctuations; trade restrictions; logistical challenges; variations in taxes; and changes in labor conditions, labor strikes and difficulties in staffing and managing international operations. Failure to successfully manage risks associated with our international operations could result in higher operating costs than anticipated or could delay or limit our ability to generate revenue and income from construction operations in key international markets.

The U.S. federal government has approved various spending bills for the construction of defense- and diplomacy-related projects and has allocated significant funds to the defense of U.S. interests around the world from the threat of terrorism. The federal government has also approved funds for development in conjunction with the relocation of military personnel into Guam. However, federal government funding levels for construction projects in the Middle East have decreased significantly over the past several years as the U.S. government has reduced the number of military troops and support personnel in the region. As a result, we have seen a decrease in the number and size of federal government projects available to us in this region. Any decrease in U.S. federal government funding for projects in Guam or in other U.S. Territories or countries in which we are pursuing work may result in project delays or cancellations, which could reduce our revenue and earnings.

Table of Contents

Finally, the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act of 2010, and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business. While our policies mandate compliance with these anti-bribery laws, there is no assurance that our policies and procedures will protect us from circumstances or actions that could result in possible criminal penalties or other sanctions, including contract cancellations or debarment and loss of reputation, any of which could have a material adverse impact on our business, financial condition, and results of operations.

12Adverse health events, such as an epidemic or a pandemic, could adversely impact our business.

~~Table~~From time to time, various diseases have spread across the globe, such as the recent coronavirus. If a disease spreads sufficiently to cause an epidemic or a pandemic, our business or the businesses of ~~Contents~~our suppliers, subcontractors or customers could be adversely impacted.

Downgrades in our credit ratings could have a material adverse effect on our business and financial condition.

The Company’s debt rating was downgraded by a major credit rating agency on May 17, 2019. The credit ratings assigned to us and our debt are subject to ongoing evaluation by credit rating agencies and could change based upon, among other things, our results of operations and financial condition. Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under review for a downgrade, could have a material adverse effect on our costs and availability of capital, which could in turn have a material adverse effect on our financial condition, results of operations, cash flows and our ability to satisfy our debt service obligations. Negative changes in our credit ratings could also result in more stringent covenants and higher interest rates with regard to any new debt.

The phase-out of the London Interbank Offered Rate (“LIBOR”), or the replacement of LIBOR with a different reference rate, may adversely affect interest rates paid on some of our loans and consequently, our earnings and cash flows.

Borrowings under our revolving credit facility and the variable portion of our equipment financing and mortgages use interest rates in relation to LIBOR. In 2017, the United Kingdom’s Financial Conduct Authority, which regulates LIBOR, announced that it intends to phase out LIBOR by the end of 2021. It is unclear if LIBOR will cease to exist at that time or if new methods of calculating LIBOR will be established such that it continues to exist after 2021. The expected phase out of LIBOR could cause market volatility or disruption and may adversely affect our access to the capital markets and cost of funding.

Conversion of our outstanding Convertible Notes could dilute ownership interests of existing stockholders and could adversely affect the market price of our common stock.

Based on the terms of the indenture for our Convertible Notes, we may redeem the Convertible Notes in cash, shares of our common stock or a combination thereof. Should we redeem the Convertible Notes for shares of our common stock, the ownership interests of existing stockholders may be diluted and any subsequent sales in the public market of our common stock issued upon such conversion could cause the price of our common stock to decline. In addition, the existence of the Convertible Notes may encourage short selling by market participants because a conversion of the Convertible Notes could depress the price of our common stock.

Our chairman and chief executive officer could exert influence over the Company due to his position and significant ownership interest.

As of December 31, ~~2018,~~2019, our chairman and chief executive officer, Ronald N. Tutor, and three trusts controlled by Mr. Tutor (the “Tutor Group”) owned approximately ~~17%~~16% of the outstanding shares of our common stock. Additionally, one of our current directors was appointed by Mr. Tutor pursuant to his right to nominate one member to our Board of Directors, so long as the Tutor Group owns at least 11.25% of the outstanding shares of our common stock. Accordingly, Mr. Tutor could exert influence over the outcome of a range of corporate matters, including the election of directors and the approval or rejection of other extraordinary transactions, such as a takeover attempt or sale of the Company or its assets.

Comparison of Fiscal Years 2018 and 2017

For a discussion comparing our fiscal 2018 results to fiscal 2017, refer to Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Form 10-K for the fiscal year ended December 31, 2018, as filed with the Securities and Exchange Commission on February 27, 2019.

Executive Overview

Consolidated revenue for ~~2018~~2019 was $4.5 billion, ~~compared~~which is comparable to ~~$4.8 billion for 2017. The decrease~~revenue in 2018. Revenue in 2019 was primarily driven by a mix of Building segment projects in California, including a large technology project that completed in the second quarter of 2018, and various electrical projects in New York within the Specialty Contractors segment, as revenue generated from project execution activities for certain new projects starting up did not fully offset reduced revenue from projects that have completed or are nearing completion.

Consolidated revenue for 2017 was $4.8 billion compared to $5.0 billion for 2016. The slight reduction was primarily due to decreased volume in our Building and Civil segments attributed to various projects that were completed or nearing completion. The decrease was partially offsetfavorably impacted by higher volume on certain Civil segment projects, which was mostly offset by a $123.9 million reduction in ~~California and New York, as well as certain Building segment projects~~revenue associated with the SR 99-related charge discussed in ~~California and Maryland. In addition, revenue in 2017 was negatively impacted by~~ the ~~timing~~following paragraph.

For the year ended December 31, 2019, the Company reported a loss from construction operations of ~~certain Building and Civil projects that were in ramp-up stages.~~

~~Table of Contents~~

~~Despite the volume reduction,~~$365.0 million compared to income from construction operations ~~increased 7% in 2018 to~~of $191.9 million ~~compared~~in 2018. The loss was primarily driven by the $379.9 million pre-tax non-cash goodwill impairment charge recorded in 2019 (see Note 6 of the Notes to ~~$179.5 million~~Consolidated Financial Statements). Adjusted income from construction operations for 2019, which is a non-GAAP financial measure and excludes the non-cash goodwill impairment charge, was $14.9 million. (For a discussion of non-GAAP financial measures, including a reconciliation of non-GAAP financial measures to the most nearly comparable GAAP financial measures, see the section below titled Non-GAAP Financial Measures.) The decrease in ~~2017. The increase~~adjusted income from construction operations was primarily due to ~~unfavorable adjustments that occurred in 2017 on certain mechanical projects in New York ($13.1~~a $166.8 million in the aggregate, none of which were individually material) and California (which were not material individually or in the aggregate), as well as general and administrative expense savings in 2018 largelypre-tax charge related to ~~lower compensation costs.~~the adverse SR 99 jury verdict. The ~~increase was partially offset by a pre-tax~~SR 99-related charge inprincipally impacted the ~~first quarter of 2018 totaling $17.8 million, which was attributable~~Civil segment. For additional information, refer to the ~~unexpected adverse outcome~~Alaskan Way Viaduct Matter discussion in Note 8 of ~~an arbitration decision on a completed Civil segment project in New York.~~the Notes to Consolidated Financial Statements.

Income from construction operations for 2017 was $179.5 million compared to $201.9 million for 2016. The decrease was driven by the unfavorable adjustments in 2017 related to certain mechanical projects mentioned in the preceding paragraph, the lower volume in 2017 relative to 2016 and higher compensation-related general and administrative expenses in 2017. The decrease was partially offset by work performed on certain higher margin Civil and Building projects.

The effective tax rate for 2019 was 15.4% compared to 26.3%~~, (0.4)%~~ for 2018. During 2019, the Company recognized an income tax benefit of $65.6 million as a result of the pre-tax loss primarily related to the goodwill impairment and ~~35.7%~~SR 99 charges mentioned above. The goodwill impairment charge was not fully deductible for ~~2018, 2017~~income taxes, which significantly reduced the tax benefit and ~~2016, respectively. The~~ effective tax ~~rates~~rate for ~~2018 and 2017 were favorably impacted by~~ the ~~enactment of the TCJA, which was signed into law on December 22, 2017.~~year. For a further discussion of the effect of the ~~TCJA,~~goodwill impairment charge, see Note 5 of the Notes to Consolidated Financial Statements.

~~Earnings~~Diluted loss per share for 2019 was $7.72 compared to diluted earnings per share ~~was~~of $1.66 ~~$2.92 and $1.92 in 2018, 2017 and 2016, respectively.~~for 2018. The ~~decreased~~substantially reduced earnings in ~~2018~~2019 were primarily attributable to the ~~$17.8 million charge mentioned above. The higher earnings in 2017 compared to 2016 were primarily due to the~~ above-mentioned ~~tax benefit of $53.3 million~~goodwill impairment ($~~1.05~~6.58 per diluted share)~~, as well as the 2017 gain on a $37.0 million~~ and SR 99-related ($~~0.43~~2.38 per diluted share) ~~legal settlement mentioned above (also see Note 9 of the Notes to Consolidated Financial Statements).~~charges.

Consolidated new awards in ~~2018~~2019 were ~~$6.5~~$6.4 billion compared to ~~$5.8~~$6.5 billion in ~~2017 and $3.7 billion in 2016.~~2018. The Civil and Building segments were the predominant contributors of new awards during ~~2018~~2019 and ~~2016. The Civil segment was the major contributor of new awards during 2017.~~2018.

Consolidated backlog as of December 31, 2019 was ~~$9.3~~$11.2 billion ~~$7.3 billion and $6.2~~compared to $9.3 billion as of December 31, ~~2018, 2017 and 2016, respectively.~~2018. The Company experienced backlog growth of ~~28%~~21% in ~~2018,~~2019, driven by various large awards in the Civil and Building segments. As of December 31, ~~2018,~~2019, the mix of backlog by segment was ~~55%~~54% for Civil, 25% for Building and ~~20%~~21% for Specialty Contractors. ~~The Company experienced backlog growth of 17% in 2017, driven by various awards in the Civil segment.~~

Most projects in the Civil segment’s backlog typically convert to revenue over a period of three to five years and in the Building and Specialty Contractors segments over a period of one to three years. We estimate that approximately $4$5 billion, or ~~45%~~44%, of our backlog as of December 31, ~~2018~~2019 will be recognized as revenue in ~~2019.~~2020.

Non-GAAP Financial Measures

To supplement our consolidated financial statements presented under generally accepted accounting principles in the United States (“GAAP”), we are presenting certain non-GAAP financial measures. We are providing these non-GAAP financial measures to disclose additional information to facilitate the comparison of past and present operations, and they are among the indicators management uses as a basis for evaluating the Company’s financial performance as well as for forecasting future periods. We believe that these non-GAAP financial measures, when considered together with our GAAP financial results, provide management and investors with an additional understanding of our business operating results, including underlying trends.

These non-GAAP financial measures, which exclude the non-cash goodwill impairment charge (as well as the tax benefit associated with this charge), include adjusted income (loss) from construction operations, adjusted net income (loss) attributable to Tutor Perini Corporation, adjusted diluted earnings (loss) per common share and adjusted effective income tax rate. We also reference adjusted operating margin for each segment, which is a non-GAAP financial measure that we define as adjusted income (loss) from construction operations as a percentage of revenue. These non-GAAP financial measures are not intended to replace the presentation of our financial results in accordance with GAAP, and they may not be comparable to other similarly titled non-GAAP financial measures presented by other companies. Reconciliations of these non-GAAP financial measures to the most nearly comparable GAAP financial measures are presented below. For the year ended December 31, 2018, there are no non-GAAP financial measures presented or included in the reconciliation tables below because the non-GAAP financial measures, as defined by the Company, do not differ from GAAP results in those periods, as the only adjustment occurred in 2019.

Revenue for ~~2018 decreased slightly~~2019 increased 12% compared to ~~2017, as the impact of certain large projects that completed or are nearing completion~~2018. The growth was approximately offset by projects that started or experienced higher volume during 2018. Revenue for 2017 decreased 4% compared to 2016 primarily due to the impact of certain projects in New York, Washington and the Midwest that were completed or nearing completion in 2017. The decrease was partially offsetprincipally driven by increased ~~activity~~project execution activities on certain mass-transit projects in California and ~~New York~~Minnesota that ~~were ramping up.~~are early in their project life cycles, as well as increased activities on the Newark Airport Terminal One project. The growth was partially offset by the revenue reduction associated with the adverse SR 99 jury verdict discussed in the section entitled Executive Overview.

Income (loss) from construction operations decreased ~~12%~~significantly in ~~2018~~2019 compared to ~~2017,~~2018, mainly due to the goodwill impairment charge. Despite the strong revenue growth, adjusted income from construction operations for 2019 decreased 65% compared to 2018, primarily due to the impact of the SR 99-related charge ($155.8 million of the $166.8 million impacted the Civil segment), partially offset by the $37.8 million reduction in general and administrative expenses associated with the remeasurement gain that resulted from the Company increasing its ownership interest in a joint venture (see Note 13 of the Notes to Consolidated Financial Statements) and income contributions related to the volume increase mentioned above.

Operating margin was (8.5)% and adjusted operating margin was 3.3% for 2019 compared to 10.6% in 2018. The reduction in operating margin for 2019 was driven by the goodwill impairment and SR 99 charges mentioned above. The decrease in adjusted operating margin for 2019 was principally due to the ~~$17.8 million charge in the first quarter of 2018 discussed above in the~~ ~~Executive Overview. Income from construction operations increased 11% in 2017 compared to 2016, principally due to increased project execution activity on certain higher-margin projects in California and New York.~~

~~Operating margin was 10.6% in 2018 compared to 12.0% in 2017 and 10.3% in 2016. The operating margin changes in 2018 and 2017 were primarily due to the reasons discussed~~factors mentioned above that ~~impacted~~drove the changes to revenue and adjusted income from construction operations.

New awards in the Civil segment totaled $2.7 billion in 2019 compared to $2.6 billion in ~~2018, $3.0~~2018. New awards in 2019 included the $1.4 billion Purple Line Section 3 Stations project and the $432 million Division 20 Portal Widening and Turnback Facility project, both in ~~2017~~California; the $253 million Culver Line Communications-Based Train Control project in New York; and ~~$1.6 billion~~a $178 million military facilities project and a $122 million wastewater treatment project, both in ~~2016.~~ Guam.

New awards in 2018 included the $800 million Minneapolis Southwest Light Rail Transit project in Minnesota; the Civil segment’s 50% share of the $1.4 billion Newark Airport Terminal One project, net of subcontracts awarded to Five Star Electric and WDF in the Specialty Contractors segment (with the remaining 50% share of the project booked in the Building segment’s backlog); a $410 million mass-transit project in California; a $121 million water tunnel project in California; a $93 million bridge project in New York; and an $82 million aircraft maintenance facility and hangar project in Guam.

We have a committed line of credit totaling $350 million, which may be used for revolving loans, letters of credit and/or general purposes. We believe that cash generated from operations, along with our unused credit capacity of ~~$309~~$236 million and available

cash ~~position~~balances as of December 31, ~~2018,~~2019, will be sufficient to fund any working capital needs for the next 12 months. As discussed in the section entitled Debt below, the Company intends to modify or replace the 2017 Credit Facility and/or repurchase or exchange the Convertible Notes in 2020.

Cash and Working Capital

Cash and cash equivalents were $193.7 million as of December 31, 2019 compared to $116.1 million as of December 31, ~~2018 compared to $192.9 million as of December 31, 2017.~~2018. Cash immediately available for general corporate purposes was ~~$51.7~~$43.8 million and ~~$94.7~~$51.7 million as of December 31, ~~2018~~2019 and ~~2017,~~2018, respectively, with the remainder being amounts held by our consolidated joint ventures and also our proportionate share of cash held by our unconsolidated joint ~~ventures and also amounts~~ventures. Cash held by our ~~consolidated~~ joint ventures ~~which, in both cases, were~~was available only for joint venture-related uses, including distributions to joint venture partners. In addition, our restricted cash and restricted investments, held primarily to secure insurance-related contingent obligations, totaled $79.4 million as of December 31, 2019 compared to $61.9 million as of December 31, ~~2018 compared to $57.8 million as of~~2018.

During the year ended December 31, ~~2017.~~

2019, net cash provided by operating activities was $136.5 million (with $248.0 million provided in the second half of 2019), due primarily to changes in net investment in working capital and cash generated from income sources. The change in working capital primarily reflects an increase in billings in excess of costs and estimated earnings (“BIE”), partially offset by increases in accounts receivable and retainage receivable. During the year ended December 31, 2018, net cash provided by operating activities was $21.4 million due primarily to cash generated from income sources mostly offset by changes in net investment in working capital. The change in working capital primarily ~~reflects~~reflected an increase in costs and estimated earnings in excess of billings (“CIE”), which was partially offset by an increase in ~~billings~~BIE.

These current year improvements were partially offset by increases in retainage receivable and ~~costs and estimated earnings~~accounts receivable in ~~excess of billings, which was mostly offset by an increase in billings in excess of costs and estimated earnings.~~

~~Cash flow from operations for 2018 was $21.4 million~~2019 compared to ~~$163.6 million~~decreases in ~~2017 (which was a record high for the Company since the 2008 merger). The decrease primarily reflects a higher net investment in working capital, as costs~~2018.

During 2019 and ~~estimated earnings in excess of billings increased $108.6 million more in~~ 2018, than in 2017. In addition, cash flows from operations for 2017 benefited from a $37.0 million cash settlement associated with a legal matter, as discussed in Note 9 of the Notes to Consolidated Financial Statements. Cash flow from operations for 2017 improved $50.2 million compared to 2016 and was due to a lower net investment in working capital.

~~During 2018 and 2017,~~ we used ~~$70.2~~$76.1 million and ~~$87.1~~$70.2 million of cash from investing activities, respectively. The net cash used in investing activities in 2019 was primarily due to $84.2 million of expenditures for the acquisition of property and equipment. The majority of our capital expenditures was for project-specific equipment purchased by our joint ventures and funded directly by our customers. The net cash used in investing activities in 2018 was primarily due to $77.1 million of expenditures for the acquisition of property and equipment. ~~The net cash used in investing activities for 2017 was attributable to investments in securities of $61.0 million and the acquisition of property and equipment of $30.3 million.~~

During ~~2018,~~2019, we ~~utilized $29.0~~generated $21.8 million of cash from financing activities principally due to increased net borrowings of $61.3 million and contributions from noncontrolling interests of $9.8 million, partially offset by distributions to noncontrolling interests of $46.5 million. Net cash used in financing activities for 2018 was $29.0 million, primarily due to distributions to noncontrolling interests of $29.0 million and an earn-out payment related to a 2011 acquisition of $16.0 million, partially offset by increased net borrowings of $14.8 million. Net cash used in financing activities for 2017 was $75.4 million, primarily due to the net paydown of debt, distributions paid to noncontrolling interests of $17.5 million and the payment of $15.3 million in debt issuance and extinguishment costs related to debt restructuring transactions.

As of December 31, ~~2018,~~2019, we had working capital of $1.4 billion, a ratio of current assets to current liabilities of 1.66 and a ratio of debt to equity of 0.58 compared to working capital of $1.6 billion, a ratio of current assets to current liabilities of 1.99 and a ratio of debt to equity of 0.43 ~~compared to working capital of $1.5 billion, a ratio of current assets to current liabilities of 1.94 and a ratio of debt to equity of 0.43~~ at December 31, ~~2017.~~2018.

Debt

Summarized below are the key terms of our debt as of December 31, ~~2018.~~2019. For additional information, refer to Note 7 of the Notes to Consolidated Financial Statements, as applicable.

2017 Credit Facility

On April 20, 2017, wethe Company entered into ~~a credit agreement (the “2017~~the 2017 Credit ~~Facility”)~~Facility with SunTrust Bank, now known as Truist Bank, as Administrative Agent, Swing Line Lender and L/C Issuer and a syndicate of other lenders. The 2017 Credit Facility provides for a $350 million revolving credit facility (the “2017 Revolver”) and a sublimit for the issuance of letters of credit and swingline loans up to the aggregate amount of $150 million and $10 million, respectively, both maturing on April 20, 2022 unless any of the Convertible Notes are outstanding on December 17, 2020, in which case all such borrowings will mature on December 17, 2020, ~~(subject~~provided that (i) if the Convertible Notes are refinanced in full with the proceeds of permitted refinancing indebtedness in accordance with the terms of the 2017 Credit Facility, the maturity date for the 2017 Credit Facility will remain April 20, 2022 and (ii) if the Company issues “New Convertible Notes” (as defined in the 2017 Credit Facility), the maturity date for the 2017 Credit Facility will be the earlier of (x) April 20, 2022 or December 17, 2020 if Convertible Notes are outstanding on December 17, 2020 and (y) 90 days prior to ~~certain further exceptions).~~the maturity date for such New Convertible Notes. In addition, the 2017 Credit Facility permits additional borrowings in an aggregate amount of $150 million, which can be in the form of increased capacity on the 2017 Revolver or the establishment of one or more term loans. On May 7, 2019, certain provisions of the 2017 Credit Facility were amended, including setting the maximum leverage ratio at 3.50:1.00

for the remainder of its term, thus eliminating the step down from 3.50:1.00 to 3.25:1.00. For additional information regarding the terms of our 2017 Credit Facility, refer to Note 7 of the Notes to Consolidated Financial Statements.

~~Table of Contents~~

The table below presents our actual and required consolidated fixed charge coverage ratio and consolidated leverage ratio under the 2017 Credit Facility for the period, which are calculated on a rolling four-quarter basis:



	Twelve Months Ended December 31, ~~2018~~2019
	Actual	Required
Fixed charge coverage ratio	~~3.19~~3.57 to 1.00	> or = 1.25 : 1.00
Leverage ratio	~~2.74~~2.60 to 1.00	< or = 3.50 : 1.00

As of ~~the filing date of this Form 10-K,~~December 31, 2019, we ~~are~~were in compliance and expect to continue to be in compliance with the ~~financial~~ covenants under the 2017 Credit Facility.

As a result of the aforementioned provision in the 2017 Credit Facility whereby the maturity date of the 2017 Credit Facility may be moved forward from April 20, 2022, the facility will mature on December 17, 2020 if the Convertible Notes remain outstanding at that time (the “spring-forward” provision). While the Company does not have call rights that allow it to unilaterally redeem the Convertible Notes, it intends to repurchase or exchange the Convertible Notes and/or modify or replace the 2017 Credit Facility during 2020. Various alternatives are under consideration to determine the financing arrangement that is best suited to the Company’s needs and provides the most favorable terms. The Company is currently in discussions with lenders regarding its options. Due to the spring-forward provision in the 2017 Credit Facility, all borrowings under the facility are included in “Current maturities of long-term debt” on the Consolidated Balance Sheet as of December 31, 2019.

2017 Senior Notes

On April 20, 2017, we issued $500 million in aggregate principal amount of 6.875% Senior Notes due 2025 (the “2017 Senior Notes”) in a private ~~placement.~~placement offering. Interest on the 2017 Senior Notes is payable in arrears semi-annually onin May 1 and November 1 of each year, beginning onin November 1, 2017.

~~Repurchase and Redemption of Notes and Termination of Credit Facility~~

We used proceeds from the 2017 Senior Notes and 2017 Revolver to repurchase or redeem our previously outstanding senior notes, to pay off and terminate our previous credit facility which included a term loan and revolver, as well as to pay accrued but unpaid interest and fees.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations is based upon our Consolidated Financial Statements, which have been prepared in accordance with GAAP. Our significant accounting policies are described in Note 1 of the Notes to Consolidated Financial Statements. The preparation of the Consolidated Financial Statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Estimates are based on information available through the date of the issuance of the financial statements; accordingly, actual results in future periods could differ from these estimates. Effective January 1, 2018, the Company adopted Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers (“ASC 606”). See Note 1(d), Note 3 and Note 4 of the Notes to Consolidated Financial Statements for more information. Significant judgments and estimates used in the preparation of the Consolidated Financial Statements apply to the following critical accounting policies:

Method of Accounting for Contracts — Contract revenue is recognized over time using the cost-to-cost method which measures progress towards completion based on the ratio of contract costs incurred to date compared to total estimated costs for each performance obligation. The estimates used in accounting for contracts with customers require judgment and assumptions regarding both future events and the evaluation of contingencies such as the impact of change orders, liability claims, other contract disputes, the achievement of contractual performance standards and potential variances in project schedule and costs. Changes to the total estimated contract cost, either due to unexpected events or revisions to management’s initial estimates, for a given project are recognized in the period in which they are determined.

In certain instances, we provide guaranteed completion dates and/or achievement of other performance criteria. Failure to meet schedule or performance guarantees could result in unrealized incentive fees and/or liquidated damages. In addition, depending on the type of contract, unexpected increases in contract cost may be unrecoverable, resulting in total cost exceeding revenue realized from the projects. The Company generally provides limited warranties for work performed, with warranty periods typically extending for a limited duration following substantial completion of the Company’s work on a project. Historically, warranty claims have not resulted in material costs incurred.

Claims arising from construction contracts have been made against the Company by customers, and the Company has made claims against customers for costs incurred in excess of current contract provisions. The Company recognizes revenue for claims as variable consideration in accordance with ASC 606. Assumptions as to the occurrence of future events and the likelihood and amount of variable consideration are made during the contract performance period. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of anticipated performance and all information (historical, current and forecasted) that is reasonably available to management. Estimated amounts are only included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Back charges to suppliers or subcontractors are recognized as a reduction of cost when it is determined that recovery of such cost is probable and the amounts can be reliably estimated. Disputed back charges are recognized when the same requirements described above for variable consideration have been satisfied.

Construction Joint Ventures —Certain contracts are executed through joint ventures. The arrangements are often formed for the execution of single contracts or projects and allow the Company to share risks and secure specialty skills required for project execution.

In accordance with ASC 810, Consolidation (“ASC 810”) the Company assesses its joint ventures at inception to determine if any meet the qualifications of a variable interest entity (“VIE”). The Company considers a joint venture a VIE if either (a) the total equity investment is not sufficient to permit the entity to finance its activities without additional subordinated financial support, (b) characteristics of a controlling financial interest are missing (either the ability to make decisions through voting or other rights, the obligation to absorb the expected losses of the entity or the right to receive the expected residual returns of the entity), or (c) the voting rights of the equity holders are not proportional to their obligations to absorb the expected losses of the entity and/or their rights to receive the expected residual returns of the entity and substantially all of the entity’s activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights. Upon the occurrence of certain events outlined in ASC 810, the Company reassesses its initial determination of whether the joint venture is a VIE.

The Company also evaluates whether it is the primary beneficiary of each VIE and consolidates the VIE if the Company has both (a) the power to direct the economically significant activities of the entity and (b) the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to the VIE. The Company considers the contractual agreements that define the ownership structure, distribution of profits and losses, risks, responsibilities, indebtedness, voting rights and board representation of the respective parties in determining whether it qualifies as the primary beneficiary. The Company also considers all parties that have direct or implicit variable interests when determining whether it is the primary beneficiary. When the Company is determined to be the primary beneficiary, the VIE is consolidated. In accordance with ASC 810, management’s assessment of whether the Company is the primary beneficiary of a VIE is performed continuously.

~~Table of Contents~~

For construction joint ventures that do not need to be fully consolidated, the Company accounts for its interest in the joint ventures using the proportionate consolidation method, whereby the Company’s proportionate share of the joint ventures’ assets, liabilities, revenue and cost of operations are included in the appropriate classifications in the Company’s consolidated financial statements. Intercompany balances and transactions have been eliminated. See Note 1(b) and Note 1314 of the Notes to Consolidated Financial Statements for additional discussion regarding VIEs.

Recoverability of Goodwill — Goodwill represents the excess of amounts paid over the fair value of net assets acquired from an acquisition. In order to determine the amount of goodwill resulting from an acquisition, we perform an assessment to determine the value of the acquired company's tangible and identifiable intangible assets and liabilities. In our assessment, we determine whether identifiable intangible assets exist, which typically include backlog, customer relationships and trade names.

We test goodwill for impairment annually as of October 1 of each ~~year for our Civil, Building and Specialty Contractors operating segments, which are the same as our reporting units for goodwill impairment analysis.~~year. This test requires us to estimate the fair value of each reporting unit carrying goodwill, using income and market approaches and to compare the calculated fair value of each reporting unit to its carrying value, which is equal to the reporting unit’s net assets. If the calculated fair value of a reporting unit is less than its carrying value, we recognize an impairment charge equal to the difference.

The impairment evaluation process requires assumptions that are subject to a high degree of judgment such as revenue growth rates, profitability levels, discount rates, industry market multiples and ~~weighted average~~weighted-average cost of capital ~~(WACC)~~(“WACC”). Changes in these assumptions would impact the results of our impairment tests.

As part of our annual impairment test, we also assess the reasonableness of the estimated fair value of our reporting units by comparing the sum of our reporting units’ fair values to our market capitalization and calculating an implied control premium (the excess of the aggregate fair values of our reporting units over our market capitalization). The reasonableness of this implied control premium is evaluated by considering a number of factors including, but not limited to, the following:

~~Market control premium: We compare our implied control premium to those observed in industry-specific mergers and acquisition transactions over a sustained period of time with an emphasis on more recent transactions.~~

~~Sensitivity analysis~~: We perform a sensitivity analysis to determine the minimum control premium required to recover our carrying value as of our testing date. The minimum control premium required is then compared to the observable market information.

~~Other entity-specific factors~~: A significant portion of our common stock is owned by our Chairman and CEO. As a result, our public float, which represents the percentage of our total outstanding shares of common stock that are freely traded by public investors, is significantly lower relative to that of our peers. While this circumstance does not impact the fair value of our reporting units, we believe it leads to an inherent marketability discount impacting our stock price.

During interim periods, including those subsequent to the Company’s October 1 annual test date, we evaluate events and circumstances, including, but not limited to, an examination of macroeconomic conditions, cost factors, overall financial performance by each reporting unit, other relevant entity-specific events, and trends in the stock prices of our Company and peers to determine if such factors indicate that it is likely that the goodwill for one or more of our reporting units is impaired, thus warranting the performance of ~~the annual~~a quantitative impairment test sooner than the fourth quarter of the year. The Company performed an interim impairment test as of June 1, 2019 and recognized a non-cash impairment loss totaling $379.9 million, which eliminated the carrying value of goodwill for the Building and Specialty Contractors reporting units. See Note 1(g) and Note 6 of the Notes to Consolidated Financial Statements.

During the fourth quarter of ~~2018,~~2019, we conducted our annual goodwill impairment test and determined that goodwill was not impaired since the estimated fair value for each of our reporting units exceeded their respective net book values. Further, the implied control premium was consistent with or within a reasonable range of actual premiums paid in industry-specific merger and acquisition transactions observed over a sustained period of time. The estimated fair value of the Civil ~~and Building reporting units were substantially in excess of their carrying value. The estimated fair value of our Specialty Contractors~~ reporting unit exceeded its ~~carrying~~net book value, but not by a significant amount. As such, there is a risk of goodwill impairment if future events are less favorable than what we assumed or estimated in our impairment analysis.

The Company considered relevant events and circumstances since the annual goodwill impairment test, including, but not limited to, an examination of macroeconomic conditions, industry and market conditions, cost factors, overall financial performance by each reporting unit, other relevant entity-specific events, and trends in the stock prices of the Company and its peers. The Company has continued to observe significant opportunities in a robust marketplace which have led to sizable new awards and significant growth in backlog for ~~each of~~ the ~~Company’s~~Civil reporting ~~units, including the Specialty Contractors reporting unit, which has backlog margins in excess of historical averages.~~unit. In considering the totality of qualitative factors known as of the reporting date, we determined that

no triggering events occurred or circumstances changed since the date of our October 1 annual test that would more likely than not reduce the fair value of the ~~Company’s~~Civil reporting ~~units~~unit below ~~their~~its carrying ~~amounts. Accordingly, an interim impairment test was not required. However, we~~amount. We will continue to monitor events occurring or circumstances ~~such as~~changing which may suggest that goodwill should be reevaluated.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures — An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as defined by Rule 13a-15(e) under the Exchange Act, as of December 31, ~~2018~~2019 was made under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, ~~2018,~~2019, our disclosure controls and procedures were effective, in that they provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act were recorded, processed, summarized and reported within the time periods specified in the SEC’s rules. Our disclosure controls and procedures are designed to ensure that information we are required to disclose in such reports is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.

Management’s Report on Internal Control over Financial Reporting — Our management, under the supervision of our Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining an adequate system of internal control over financial reporting as such term is defined in Exchange Act Rules 13a-15(f). In designing and evaluating our system of internal control over financial reporting, we recognize that inherent limitations exist in any control system no matter how well designed and operated, and we can only provide reasonable, not absolute, assurance of achieving the desired control objectives. In making this assessment, management utilized the criteria issued in Internal Control — Integrated Framework (2013) issuedby the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management concluded that, as of December 31, ~~2018,~~2019, our internal control over financial reporting was effective based on those criteria.

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

Deloitte & Touche LLP, the independent registered public accounting firm that audited our consolidated financial statements included in this Annual Report on Form 10-K, has issued an attestation report on the Company’s internal control over financial reporting as of December 31, ~~2018.~~2019.

Changes in Internal Control over Financial Reporting — There were no changes in our internal control over financial reporting for the quarter ended December 31, ~~2018~~2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Tutor Perini Corporation and subsidiaries (the “Company”) as of December 31, ~~2018,~~2019, 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 Company maintained, in all material respects, effective internal control over financial reporting as of December 31, ~~2018,~~2019, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, ~~2018,~~2019, of the Company and our report dated February ~~27, 2019,~~26, 2020, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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

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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of

Tutor Perini Corporation

~~Sylmar, California~~

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Tutor Perini Corporation and subsidiaries (the "Company") as of December 31, ~~2018~~2019 and ~~2017,~~2018, the related consolidated statements of ~~income,~~operations, comprehensive income (loss), changes in equity, and cash flows, for each of the three years in the period ended December 31, ~~2018,~~2019, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, ~~2018~~2019 and ~~2017,~~2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, ~~2018,~~2019, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, ~~2018,~~2019, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February ~~27, 2019,~~26, 2020, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Revenue, Accounts Receivable, Contract Assets and Liabilities — Accounting for Construction Contracts– Refer to Notes 1, 3, 4, and 8 to the financial statements

Critical Audit Matter Description

The Company recognizes revenue for construction contracts over the contract term (“over time”) as construction work progresses. The accounting for these contracts involves judgment, particularly as it relates to the process of determining total estimated revenue (transaction price) and estimating total costs to be incurred at contract completion. Costs of operations are typically recognized as incurred, and the Company’s revenues, including estimated profits, are recorded proportionately as costs are incurred based on the ratio of costs incurred to date to the total estimated costs at completion for the respective performance obligations. Assumptions as to the occurrence of future events and the likelihood and amount of variable consideration, including the impact of change orders, claims, contract disputes and the achievement of contractual performance criteria, and award or other incentive fees are made during the contract performance period (collectively referred to as “variable consideration”). The Company estimates variable consideration at the most likely amount it expects to receive, and includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Also, the Company often engages subcontractors, suppliers, or vendors, to provide underlying materials or services, or a combination of both. Judgment is involved in determining estimated recoveries from disputes regarding performance under these contracts (“back charges”), which are a reduction in costs and are recorded as a receivable on the consolidated balance sheet.

Given the significant judgment necessary to account for the Company’s construction contracts including the use of estimates, such as total estimated revenue, total costs to be incurred at contract completion, variable consideration and back charges, which are complex

F-2

Table of Contents

and subject to many variables, auditing the corresponding balances and related accounting estimates required extensive audit effort due to the complexity of these estimates, and a high degree of auditor judgment when performing audit procedures and evaluating the results of those procedures.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to management’s estimates and judgments included within the Company’s total estimated revenues, total costs to be incurred at contract completion, variable consideration, and back charges included the following, among others:

We tested the effectiveness of controls over revenues, including those over the determination of estimated costs at completion of the contract, total estimated revenue (including the estimated percentage of completion), variable consideration (including significant change orders and claims), and back charges.

We selected a sample of construction contracts and performed the following:

oCompared the total estimated revenue (transaction price), including estimated variable consideration, to the consideration expected to be received based on current rights and obligations under the contracts and any modifications that were agreed upon with the customers.

oWe evaluated the reasonableness of the estimated variable consideration by 1) evaluating the information supporting management’s judgment as to the cause and contractual rights and 2) testing the accuracy of the identification of the underlying costs.

oTested the accuracy and completeness of costs incurred to date.

oEvaluated the reasonableness of management’s estimates of total cost and profit at completion by:

Evaluating management’s ability to achieve the estimates of total cost and profit by performing corroborating inquiries with the Company’s project managers, and comparing the estimates to management’s work plans, engineering specifications, and supplier contracts.

Comparing management’s estimates to supporting documents for those estimates, when applicable.

Evaluating management’s ability to accurately estimate total costs and profits at completion by comparing actual costs and profits to management’s historical estimates for performance obligations that have been fulfilled.

Evaluating trends on changes in estimates and obtaining evidence on timing and amounts supporting these changes in estimates.

oTested the mathematical accuracy of management’s calculation of revenue recognized.

We evaluated selected quarter over quarter changes in contract profit estimates by obtaining explanations from the Company’s project managers regarding timing and amount and corroborating these inquiries by reading documents such as management work plans, customer communications, invoices and supplier communications.

Performed procedures on recorded back charges to evaluate the reasonableness of the estimated recovery by 1) evaluating the information supporting management’s judgment as to the cause and contractual rights and 2) testing the accuracy of the identification of the underlying costs.

Goodwill – Refer to Notes 1 and 6 to the financial statements

Critical Audit Matter Description

The Company’s evaluation of goodwill for impairment involves the comparison of the fair value of each reporting unit (which correspond to the Company’s operating segments) to its carrying value. The Company determines the fair value of its reporting units using the income approach and market approach valuation methodologies. The determination of fair value using the income-based approach requires management to make significant estimates and assumptions related to projected operating margins, cash flows generated from existing work and new awards, and projected investments in working capital (collectively, the “forecasted financial information”), as well as the discount rates and weighted-average cost of capital (“WACC”). The determination of fair value using the market-based approach requires management to make significant assumptions, including those related to the forecasted financial information referred to above and the industry-comparable multiples to be used for each of its reporting units. The Company determines the valuation of each reporting unit based upon a weighted-average value of the income approach and market approach valuation methods. As appropriate, the Company also assesses the reasonableness of the estimated fair value of the reporting units by comparing the sum of the reporting units’ fair values to the Company’s market capitalization and calculating an implied control premium (the excess of the aggregate fair values of the reporting units over the Company’s market capitalization). In evaluating the results there are various quantitative and qualitative factors that need to be considered and could involve subjective judgment. During the second quarter of 2019, the Company identified an interim impairment indicator in its goodwill balance. The Company performed an interim impairment test and determined that the fair value of each of the reporting units was below the carrying value, leading to a pre-tax impairment charge of $379.9 million and leaving a $205.1 million post-impairment goodwill balance solely attributable to the Civil reporting unit.

We identified goodwill as a critical audit matter because small changes to valuation assumptions, specifically the forecasted financial information, discount rates, WACC, and industry-comparable multiples, could have a significant impact on the reporting unit concluded value for both the interim and annual impairment tests, and changes to the reporting unit concluded value impacts the implied control premium calculated from the reconciliation between the reporting unit’s fair values and the Company’s market

capitalization, which was performed during the interim impairment test. Auditing these assumptions involved extensive audit effort, including the need to involve our fair value specialists, due to the complexity of these assumptions and a high degree of auditor judgment when performing audit procedures and evaluating the results of those procedures.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the forecasted financial information, discount rates, WACC, and industry-comparable multiples for the reporting units, for both the interim and the annual impairment tests, included the following, among others:

We tested the effectiveness of controls within the goodwill impairment test process, including those over the forecasted financial information, the selection of the industry-comparable multiples, WACC, and discount rates, as well as the identification of interim impairment indicators.

We evaluated management’s historical ability to accurately forecast by comparing actual results to management’s previous forecasted financial information for the same period.

We evaluated the reasonableness of management’s forecasted financial information by comparing the forecasted financial information to (1) historical results, (2) internal communications to management and the Board of Directors, (3) reporting units’ backlog, and (4) forecasted financial information included in the Company’s press releases, as well as analyst and industry reports of the Company and companies in its peer group.

We considered the impact of circumstances affecting the industry including, but not limited to, changes in the legal and business environment.

With the assistance of our fair value specialists, we evaluated the WACC and discount rates, including testing the underlying source information and the mathematical accuracy of the calculations, and developing a range of independent estimates of the discount rates and comparing those to the WACC and discount rates selected by management.

With the assistance of our fair value specialists, we evaluated the industry-comparable multiples, including testing the underlying source information and mathematical accuracy of the calculations, the acceptability of the selected companies within the Company’s peer group, and comparing the multiples selected by management to companies in the engineering and construction industry.

With the assistance of our fair value specialists, we evaluated the reasonableness of the quantitative and qualitative factors considered in the reconciliation between the reporting units’ fair values and the Company’s market capitalization and implied control premium as of the interim impairment test date. We evaluated factors such as implied control premiums in other mergers and acquisition transactions in the industry, ownership of the Company’s common stock, market trends, and vertical-integration between reporting units.

We evaluated the selected industry-comparable multiples by comparing to those used in the prior year, those used in the different reporting units and to current facts and circumstances affecting the reporting unit.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies

(a) Basis of Presentation

The accompanying consolidated financial statements have been prepared in compliance with generally accepted accounting principles in the United States (“GAAP”) as codified in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”).

(b) Principles of Consolidation

The consolidated financial statements include the accounts of Tutor Perini Corporation and its wholly owned subsidiaries (the “Company”). The Company occasionally forms joint ventures with unrelated third parties for the execution of single contracts or projects. The Company assesses its joint ventures ~~at inception~~ to determine if they meet the qualifications of a variable interest entity (“VIE”) in accordance with ASC 810, Consolidation (“ASC 810”). If a joint venture is a VIE and the Company is the primary beneficiary, the joint venture is fully consolidated (See Note ~~13 below)~~14). If a joint venture is not a VIE, it may be consolidated under the voting interest method if the Company holds a controlling financial interest in the joint venture. The Company is considered to hold a controlling financial interest when it is able to exercise control over the joint venture’s operating and financial decisions. For construction joint ventures that do not need to be consolidated, the Company accounts for its interest in the joint ventures using the proportionate consolidation method, whereby the Company’s proportionate share of the joint ventures’ assets, liabilities, revenue and cost of operations are included in the appropriate classifications in the Company’s consolidated financial statements. Intercompany balances and transactions have been eliminated.

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect reported amounts. These estimates are based on information available through the date of the issuance of the financial statements; therefore, actual results could differ from those estimates.

(d) Revenues

Revenue Recognition

~~Implementation of New Revenue Recognition Guidance~~

~~In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09,~~ ~~Revenue from Contracts with Customers (Topic 606)~~, as amended by subsequent ASUs (collectively, “ASC 606”) which amends the existing accounting standards for revenue recognition and establishes principles for recognizing revenue upon the transfer of promised goods or services to customers based on the expected consideration to be received in exchange for those goods or services. ~~The Company adopted this ASU effective January 1, 2018 using the modified retrospective transition method.~~The Company recognized the cumulative effect of initially applying the new revenue standard to all contracts not yet completed or substantially completed as of January 1, 2018 as an immaterial reduction to beginning retained earnings. The impact of adoption on the Company’s opening balance sheet was primarily related to the deferral of costs incurred to fulfill certain contracts that were previously recorded in income in the period incurred, but under the new standard are capitalized and amortized over the period of contract performance. The prior year comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods; however, certain balances have been reclassified to conform to the current year presentation.

~~(a)~~

~~Prior to the adoption of ASC 606, retainage receivable and payable balances were included within accounts receivable and payable, respectively.~~

~~The adoption of ASC 606 had no impact on the cash flows provided by operating activities in the Company’s Consolidated Statement of Cash Flows.~~

~~Revenue Recognition Policy~~

The Company derives revenue from long-term construction contracts with public and private customers primarily in the United States and its territories and in certain other international locations. The Company’s construction contracts are generally each accounted for as a single unit of account (i.e., as a single performance obligation).

Throughout the execution of construction contracts, the Company and its affiliated entities recognize revenue with the continuous transfer of control to the customer. The customer typically controls the asset under construction by either contractual termination clauses or by the Company’s rights to payment for work already performed on the asset under construction that does not have an alternative use for the Company.

Because control transfers over time, revenue is recognized to the extent of progress towards completion of the performance obligations. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services provided. The Company generally uses the cost-to-cost method for its contracts, which measures progress towards completion for each performance obligation based on the ratio of costs incurred to date to the total estimated costs at completion for the respective performance obligation. Incurred cost represents work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Revenue, including estimated fees or profits, is recorded proportionately as costs are incurred. Cost of operations includes labor, materials, subcontractor costs, and other direct and indirect costs, including depreciation and amortization.

Due to the nature of the work required to be performed on many of the Company’s performance obligations, estimating total revenue and cost at completion is complex, subject to many variables and requires significant judgment. Assumptions as to the occurrence of future events and the likelihood and amount of variable consideration, including the impact of change orders, claims, contract disputes and the achievement of contractual performance criteria, and award or other incentive fees are made during the contract performance period. The Company estimates variable consideration at the most likely amount it expects to receive. The Company includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of anticipated

performance and all information (historical, current and forecasted) that is reasonably available to management. Back charges to suppliers or subcontractors are recognized as a reduction of cost when it is determined that recovery of such cost is probable and the amounts can be reliably estimated. Disputed back charges are recognized when the same requirements described above for variable consideration have been satisfied.

~~TUTOR PERINI CORPORATION AND SUBSIDIARIES~~

~~NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)~~

Changes in Estimates on Construction Contracts

The Company’s estimates of contract revenue and cost are highly detailed and many factors change during a contract performance period that result in a change to contract profitability. These factors include, but are not limited to, differing site conditions; availability of skilled contract labor; performance of major material suppliers and subcontractors; on-going subcontractor negotiations and buyout provisions; unusual weather conditions; changes in the timing of scheduled work; change orders; accuracy of the original bid estimate; changes in estimated labor productivity and costs based on experience to date; achievement of incentive-based income targets; and the expected, or actual, resolution terms for claims. The factors that cause changes in estimates vary depending on the maturation of the project within its lifecycle. For example, in the ramp-up phase, these factors typically consist of revisions in anticipated project costs and during the peak and closeout phases, these factors include the impact of change orders and claims, as well as additional revisions in remaining anticipated project costs. Generally, if the contract is at an early stage of completion, the current period impact is smaller than if the same change in estimate is made to the contract at a later stage of completion. Management evaluates changes in estimates on a ~~contract by contract~~contract-by-contract basis and discloses significant changes, if material, in the Notes to ~~the~~ Consolidated Financial Statements. The cumulative catch-up method is used to account for revisions in estimates.

(e) Depreciation of Property and Equipment and Amortization of Long-Lived Intangible Assets

Property and equipment and long-lived intangible assets are generally depreciated or amortized on a straight-line basis over their estimated useful lives ranging from three to forty years.

(f) Recoverability of Long-Lived Assets

Long-lived assets are reviewed for impairment whenever circumstances indicate that the future cash flows generated by the assets might be less than the assets’ net carrying value. In such circumstances, an impairment loss will be recognized by the amount the assets’ net carrying value exceeds their fair value.

(g) Recoverability of Goodwill

The Company tests goodwill for impairment annually as of October 1 for each reporting unit and between annual tests if events occur or circumstances change which suggest that goodwill should be reevaluated. Such events or circumstances include significant changes in legal factors and business climate, recent losses at a reporting unit, and industry trends, among other factors. The Civil, Building and Specialty Contractors segments each represent a reporting ~~unit.~~unit, and the Civil reporting unit carried the remaining goodwill balance at December 31, 2019 as a result of the $379.9 million impairment loss recognized in the second quarter of 2019. The Company performs its annual quantitative impairment assessment during the fourth quarter of each year using a weighted-average of an income and a market approach. The income approach is based on estimated present value of future cash flows for each reporting ~~unit.~~unit carrying a goodwill balance. The market approach is based on assumptions about how market data relates to each reporting ~~unit.~~unit carrying a goodwill balance. The weighting of these two approaches is based on their individual correlation to the economics of each reporting ~~unit.~~unit carrying a goodwill balance. The annual quantitative assessment performed in ~~2018~~the fourth quarter of 2019 resulted in an estimated fair value ~~for each~~that exceeded the net book value of the ~~Company’s~~Civil reporting ~~units that exceeded their respective net book values;~~unit; therefore, no impairment charge was ~~necessary for 2018.~~necessary.

(h) Recoverability of Non-Amortizable Trade Names

Certain trade names have an estimated indefinite life and are not amortized to earnings, but instead are reviewed for impairment annually, or more often if events occur or circumstances change which suggest that the non-amortizable trade names should be reevaluated. The Company performs its annual ~~quantitative~~ impairment assessment during the fourth quarter of each year ~~using an income approach (relief from royalty method). The quantitative assessment performed in 2018 resulted in an estimated fair value for the~~ and may assess its non-amortizable trade names for impairment initially using a qualitative approach to determine whether conditions exist to indicate that ~~exceeded their respective net book values;~~it is more likely than not that the fair value of a trade name is less than its carrying value. If the Company concludes, based on assessment of relevant events, facts and circumstances, that it is more likely than not that the trade name’s fair value is greater than its carrying value, no further impairment testing through a quantitative assessment is required. The qualitative assessment performed for the Company’s annual impairment assessment in the fourth quarter of 2019 concluded that it was more likely than not that the trade name’s fair value was greater than its carrying value, and therefore ~~no impairment charge~~a quantitative analysis was ~~necessary for 2018.~~not required.

(i) Income Taxes

Deferred income tax assets and liabilities are recognized for the effects of temporary differences between the financial statement carrying amounts and the income tax basis of assets and liabilities using tax rates expected to be in effect when such differences reverse. Income tax positions must meet a more-likely-than-not threshold to be recognized. The Company recognizes interest and penalties related to uncertain tax positions as a component of the income tax provision.

(j) Earnings Per Common Share (EPS)

Basic EPS and diluted EPS are calculated by dividing net income attributable to Tutor Perini Corporation by the following: for basic EPS, the weighted-average number of common shares outstanding during the period; and for diluted EPS, the sum of the ~~weighted-~~

For the year ended December 31, 2019, all potentially dilutive securities were excluded from the calculation of diluted EPS as a result of the net loss for the period.In accordance with ASC 260, Earnings Per Share, the settlement of the principal amount of the Convertible Notes has had no impact on diluted EPS because the Company has had the intent and ability to settle the principal amount in cash. The Company calculates the effect of the potentially dilutive restricted stock units and stock options using the treasury stock method.

Cash equivalents include short-term, highly liquid investments with maturities of three months or less when acquired. Cash and cash equivalents, consist of amounts available for the Company’s general purposes, the Company’s proportionate share of cash held by the Company’s unconsolidated joint ventures and 100% of amounts held by the Company’s consolidated joint ventures. In both cases, cash held by joint ventures is available only for joint venture-related uses, including future distributions to joint venture partners.

Amounts included in restricted cash are primarily held as collateral to secure insurance-related contingent obligations, such as insurance claim deductibles, in lieu of letters of credit.

TUTOR PERINI CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(l) Restricted Investments

The Company has restricted investments primarily held as collateral to secure insurance-related contingent obligations, such as insurance claim deductibles, in lieu of letters of credit. Restricted investments are primarily comprised of investments in corporate debt securities and U.S. government agency securities that are rated A3 or better.

(m) Share-Based Compensation

The Company’s long-term incentive plans allow the Company to grant share-based compensation awards in a variety of forms, including restricted and unrestricted stock units and stock options. Restricted stock units and stock options generally vest subject to service and/or performance requirements, with related compensation expense equal to the fair value of the award on the date of grant and recognized on a straight-line basis over the requisite period.

For share-based awards that have a service requirement, the Company accounts for forfeitures upon occurrence, rather than estimating the probability of forfeiture at the date of grant. Accordingly, the Company recognizes the full grant-date fair value of these awards on a straight-line basis throughout the requisite service period, reversing any expense if, and only if, there is a forfeiture.

F-12

~~Table of Contents~~

~~TUTOR PERINI CORPORATION AND SUBSIDIARIES~~

~~NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)~~

For share-based awards that have a performance-based vesting requirement, the Company evaluates the probability of achieving the performance criteria throughout the performance period, and will adjust share-based compensation expense if it estimates that the achievement of the performance criteria is not probable. Certain performance-based awards contain market condition components and are valued on the date of grant using a Monte Carlo simulation model. The fair value of such awards is expensed ratably over the performance period and is not adjusted for actual achievement.

(n) Insurance Liabilities

The Company typically utilizes third-party insurance coverage subject to varying deductible levels with aggregate caps on losses retained. The Company assumes the risk for the amount of the deductible portion of the losses and liabilities primarily associated with workers’ compensation and general liability coverage. In addition, on certain projects, the Company assumes the risk for the amount of the deductible portion of losses that arise from any subcontractor defaults. Losses are accrued based upon the Company’s estimates of the aggregate liability for claims incurred using historical experience and certain actuarial assumptions followed in the insurance industry. The estimate of insurance liability within the deductible limits includes an estimate of incurred but not reported claims based on data compiled from historical experience.

(o) Other Comprehensive Income (Loss)

ASC 220, Comprehensive Income, establishes standards for reporting ~~and displaying~~ comprehensive income and its components in the consolidated financial statements. The Company reports the change in pension benefit plan assets/liabilities, cumulative foreign currency translation, and change in fair value of investments ~~and change in fair value of an interest rate swap~~ as components of accumulated other comprehensive ~~loss~~income (loss) (“AOCI”).

The ~~tax effects of the~~ components of other comprehensive income (loss) and the related tax effects for ~~are~~the years ended December 31, 2019, 2018 and 2017 were as follows:

(p) Recent Accounting Pronouncements

~~In addition to the implementation of ASC 606 as discussed in 1(d), new accounting pronouncements implemented by the Company during the year ended December 31, 2018 are discussed below.~~

~~In November 2016, the FASB issued ASU 2016-18,~~ ~~Statement of Cash Flows (Topic 230): Restricted Cash~~, which requires restricted cash to be included with cash and cash equivalent balances in the statement of cash flows. The Company retrospectively adopted this ASU on January 1, 2018. The adoption of this ASU resulted in an increase of net cash used in investing activities of $45.7 million for the year ended December 31, 2017 and a decrease of net cash used in investing activities of $4.7 million for the year ended December 31, 2016.

~~In January 2017, the FASB issued ASU 2017-04,~~ ~~Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment~~ ~~(“ASU 2017-04”). This ASU simplifies the calculation of goodwill impairment by eliminating Step 2 of the impairment test prescribed by ASC 350,~~ ~~Intangibles—Goodwill and Other~~. Step 2 requires companies to calculate the implied fair value of their goodwill by estimating the fair value of their assets, other than goodwill, and liabilities, including unrecognized assets and liabilities, following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. The calculated net fair value of the assets would then be compared to the fair value of the reporting unit to determine the implied fair value of goodwill, and to the extent that the carrying value of goodwill was less than the implied fair value, a loss would be recognized. Under ASU 2017-04, however, goodwill is impaired when the calculated fair value of a reporting unit is less than its carrying value, and the impairment charge will equal that difference (i.e., impairment will be calculated at the reporting unit level and there will be no need to estimate the fair value of individual assets and liabilities). This guidance will be effective for any goodwill impairment tests performed in fiscal years beginning after December 15, 2019; however, early adoption is permitted for tests performed on testing dates after January 1, 2017. The Company adopted this ASU on October 1, 2018. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.

~~In May 2017, the FASB issued ASU 2017-09,~~ ~~Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting~~. This ASU clarifies the scope of modification accounting under Topic 718 with respect to changes to the terms or conditions of a share-based payment award. Under this new guidance, modification accounting would not apply if a change to an award does not affect the total current fair value, vesting conditions or the classification of the award. The Company adopted this ASU effective January 1, 2018. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.

~~In February 2018, the FASB issued ASU 2018-02,~~ ~~Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from the Accumulated Other Comprehensive Income.~~ This ASU gives entities the option to reclassify to retained earnings tax effects related to items in accumulated other comprehensive income that the FASB refers to as having been stranded in accumulated other comprehensive income as a result of tax reform. Entities can apply the provisions of this ASU either in the period of adoption or retrospectively. The guidance is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. The Company adopted this ASU effective October 1, 2018 and elected to not reclassify the income tax effects of the tax reform from accumulated other comprehensive income to retained earnings.

~~NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)~~

~~In March 2018, the FASB issued ASU 2018-05,~~ ~~Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118~~ (“ASU 2018-05”). This ASU provides guidance for companies that may not have completed their accounting for the income tax effects of the Tax Cut and Jobs Act of 2017 (the “Tax Act”) in the period of enactment. Staff Accounting Bulletin (“SAB”) No. 118 provides for a provisional one year measurement period to finalize the accounting for certain income tax effects related to the Tax Act and requires disclosure of the reasons for incomplete accounting. The Company applied the guidance provided in SAB No. 118 in 2017 and adopted this ASU effective January 1, 2018. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.

~~The following new accounting pronouncement will be implemented in 2019.~~

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), as amended and supplemented by subsequent ASUs (collectively, ~~“ASU 2016-02”~~“ASC 842”). ~~ASU 2016-02~~ASC 842 amends the existing guidance in ASC 840, Leases. This ASU requires, among other things, the recognition of lease right-of-use (“ROU”) assets and lease liabilities by lessees for those leases currently classified as operating leases. ~~ASU 2016-02 allows~~ASC 842 allowed companies to adopt the new standard by applying either a modified retrospective method to the beginning of the earliest period presented in the financial statements or an optional transition method to initially apply the standard on January 1, 2019 and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company ~~will adopt~~adopted the standard using the optional transition method. Under this method, financial results reported in periods prior to 2019 are unchanged. The Company ~~has implemented changes~~elected the package of practical expedients which provides relief from having to ~~certain business processes, systems~~reassess (1) whether any expired or existing contracts contain leases, (2) lease classification (as operating or financing) for any expired or existing leases, and ~~internal controls~~(3) initial direct costs for any existing leases. The Company also elected to ~~support adoption of the new standard and the related disclosure requirements, including the implementation of a third-party leasing software solution.~~separate non-lease components from lease components. Based on the Company’s evaluation of ~~ASU 2016-02, the Company expects~~ASC 842, the adoption ~~to result~~on January 1, 2019 resulted in an increase of ~~approximately $40 million to $50~~$43.3 million to its assets and liabilities on the ~~consolidated balance sheets~~Consolidated Balance Sheets with ~~an immaterial~~no impact to its ~~consolidated statements~~results of ~~income~~operations or cash flows.

(a)Prior to the adoption of ASC 842, operating lease ROU assets and current and long-term operating lease liabilities were not recorded on the Consolidated Balance Sheets.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), as amended by subsequent ASUs (collectively, “ASC 606”). The Company adopted this ASU effective January 1, 2018 using the modified retrospective transition method. As such, the 2017 comparative information has not been restated and continues to be reported under the accounting standards in effect for that period.

New accounting pronouncements requiring implementation in future periods are discussed below.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, and issued subsequent amendments to the initial guidance within ASU 2019-04 and ASU 2019-05 (collectively, “ASU 2016-13”). The amendments in ASU 2016-13 replace the incurred loss impairment methodology in current practice with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to estimate credit losses. ASU 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019. The Company does not expect the adoption of ASU 2016-13 to have a material impact on its financial position, results of operations or cash flows.

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (“ASU 2019-12”), modifying ASC 740, Income Taxes (“ASC 740”). The amendments in ASU 2019-12, among other things, remove certain exceptions to the general principles in ASC 740 and seek more consistent application by clarifying and amending the existing guidance. ASU 2019-12 is effective for interim and annual reporting periods beginning after December 15, 2020. The Company is currently evaluating the new standard, which is not expected to have a material impact on the Company’s financial position, results of operations or cash flows.

State and local agencies. The Company’s state and local government customers include state transportation departments, metropolitan authorities, cities, municipal agencies, school districts and public universities. Services provided to state and local customers are primarily pursuant to contracts awarded through competitive bidding processes. Construction services for state and local government customers have included mass-transit systems, tunnels, bridges, highways, judicial and correctional facilities, schools and dormitories, health care facilities, convention centers, parking structures and other municipal buildings. The vast majority of the Company’s civil contracting and building construction services are provided in locations throughout the United States and its territories.

Federal agencies. The Company’s federal government customers include the U.S. State Department, the U.S. Navy, the U.S. Army Corps of Engineers, the U.S. Air Force and the National Park Service. Services provided to federal agencies are typically pursuant to competitively bid contracts for specific or multi-year assignments that involve new construction or infrastructure repairs or improvements. A portion of revenue from federal agencies is derived from projects in overseas locations.

Private owners. The Company’s private ~~customers~~owners (i.e., customers) include real estate developers, health care companies, technology companies, hospitality and gaming resort owners, Native American sovereign nations, public corporations and private universities. Services are provided to private customers through negotiated contract arrangements, as well as through competitive bids.

Most federal, state and local government contracts contain provisions that permit the termination of contracts, in whole or in part, for the convenience of government customers, among other reasons.

Fixed price. Fixed price or lump sum contracts are most commonly used for projects in the Civil and Specialty Contractors segments and generally commit the Company to provide all of the resources required to complete a project for a fixed sum. Usually, fixed price contracts transfer more risk to the Company, but offer the opportunity for greater profits. Billings on fixed price contracts are typically based on estimated progress against predetermined contractual milestones.

TUTOR PERINI CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Guaranteed maximum price (“GMP”). GMP contracts provide for a cost plus fee arrangement up to a maximum agreed upon price. These contracts place risks on the Company for amounts in excess of the GMP, but may permit an opportunity for greater profits than under cost plus fee contracts through sharing agreements with the owner on any cost savings that may be realized. Services provided by our Building segment to various private customers are often performed under GMP contracts. Billings on GMP contracts typically occur on a monthly basis and are based on actual costs incurred plus a negotiated margin.

Unit price. Unit price contracts are most prevalent for projects in the Civil and Specialty Contractors segments and generally commit the Company to provide an estimated or undetermined number of units or components that comprise a project at a fixed price per unit. This approach shifts the risk of estimating the quantity of units required to the project owner, but the risk of increased cost per unit is borne by the Company, unless otherwise allowed for in the contract. Billings on unit price contracts typically occur on a monthly basis and are based on actual quantity of work performed or completed during the billing period.

Cost plus fee. Cost plus fee contracts are used for many projects in the Building and Specialty Contractors segments. Cost plus fee contracts include cost plus fixed fee contracts and cost plus award fee contracts. Cost plus fixed fee contracts provide for reimbursement of approved project costs plus a fixed fee. Cost plus award fee contracts provide for reimbursement of the project costs plus a base fee, as well as an incentive fee based on cost and/or schedule performance. Cost plus fee contracts serve to minimize the Company’s financial risk, but may also limit profits. Billings on cost plus fee contracts typically occur on a monthly basis based on actual costs incurred plus a negotiated margin.

Changes in Contract Estimates that Impact Revenue

Changes to the total estimated contract revenue or cost for a given project, either due to unexpected events or revisions to management’s initial estimates, ~~for a given project~~ are recognized in the period in which they are determined. ~~Net revenue~~Revenue was negatively impacted during the year ended December 31, 2019 related to performance obligations satisfied (or partially satisfied) in prior periods by $177.5 million for various projects, none of which was individually material, except for $123.9 million that resulted from the charge related to the Alaskan Way Viaduct matter discussed in Note 8.

December 31, 2018 related to performance obligations satisfied (or partially satisfied) in prior periods was $19.4 million for various projects, none of which was individually material.

Remaining Performance Obligations

Remaining performance obligations represent the transaction price of firm orders for which work has not been performed and exclude unexercised contract options. As of December 31, 2019, the aggregate amounts of the transaction prices allocated to the remaining performance obligations of the Company’s construction contracts were $5.2 billion, $2.2 billion and $2.2 billion for the Civil, Building and Specialty Contractors segments, respectively. As of December 31, 2018, the aggregate amounts of the transaction prices allocated to the remaining performance obligations of the Company’s construction contracts ~~are~~were $4.6 billion, $2.3 billion and $1.7 billion for the Civil, Building and Specialty Contractors segments, respectively. The Company typically recognizes revenue on Civil segment projects over a period of three to five years, whereas for projects in the Building and Specialty Contractors segments, the Company typically recognizes revenue over a period of one to three years.

4. Contract Assets and Liabilities

The Company classifies contract assets and liabilities that may be settled beyond one year from the balance sheet date as current, consistent with the length of time of the Company’s project operating cycle.

Contract assets include amounts due under retainage provisions, costs and estimated earnings in excess of billings and capitalized contract costs. The amounts as included on the Consolidated Balance Sheets ~~consist~~consisted of the following:



	As of December 31,		As of January 1,		As of December 31,
(in thousands)	2018		2018		2019		2018
Retainage receivable	$	478,744	$	535,939	$	562,375	$	478,744
Costs and estimated earnings in excess of billings:
Claims		698,274		549,849		705,993		698,274
Unapproved change orders		354,000		296,591		362,264		354,000
Other unbilled costs and profits		90,021		86,318		55,287		90,021
Total costs and estimated earnings in excess of billings		1,142,295		932,758		1,123,544		1,142,295
Capitalized contract costs		37,404		32,773		80,294		37,404
Total contract assets	$	1,658,443	$	1,501,470	$	1,766,213	$	1,658,443

Retainage receivable represents amounts invoiced to customers where payments have been partially withheld pending the completion of certain milestones, satisfaction of other contractual conditions or the completion of the project. Retainage agreements vary from project to project and balances could be outstanding for several months or years depending on a number of circumstances, such as contract-specific terms, project performance and other variables that may arise as the Company makes progress towards completion. As of December 31, ~~2018,~~2019, the amount of retainage ~~receivables~~receivable estimated by management to be collected ~~or remitted~~ beyond one year is approximately ~~29%~~39% of the balance.

Costs and estimated earnings in excess of billings represent the excess of contract costs and profits (or contract revenue) over the amount of contract billings to date and are classified as a current asset. Costs and estimated earnings in excess of billings result when either: 1)(1) the appropriate contract revenue amount has been recognized over time in accordance with ASC 606, but a portion of the revenue recorded cannot be billed currently due to the billing terms defined in the contract, or 2)(2) costs are incurred related to certain claims and unapproved change orders. Claims occur when there is a dispute regarding both a change in the scope of work and the price associated with that change. Unapproved change orders occur when a change in the scope of work results in additional work being performed before the parties have agreed on the corresponding change in the contract price. The Company routinely estimates recovery related to claims and unapproved change orders as a form of variable consideration at the most likely amount it expects to receive and to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Claims and unapproved change orders are billable upon the agreement and resolution between the contractual parties and after the execution of contractual amendments. Increases in claims and unapproved change orders typically result from costs being incurred against existing or new positions; decreases normally result from resolutions and subsequent billings. As discussed in Note 8, the resolution of these claims and unapproved change orders may require litigation or other forms of dispute resolution proceedings. Other unbilled costs and profits are billable in accordance with the billing terms of each of the existing contractual arrangements and, as such, the timing of contract billing cycles can cause fluctuations in the balance of unbilled costs and profits. Ultimate resolution of other unbilled costs and profits typically involves incremental progress toward contractual requirements or milestones. The amount of costs and estimated earnings in excess of billings as of December 31, ~~2018~~2019 estimated by management to be collected beyond one year is approximately ~~$529.3~~$572.1 million.

Capitalized contract costs primarily represent costs to fulfill a contract that (1) directly relate to an existing or anticipated contract, (2) generate or enhance resources that will be used in satisfying performance obligations in the future and (3) are expected to be recovered through the contract, and are included in other current assets. Capitalized contract costs are generally expensed to the associated

contract over the period of anticipated use on the project. During the year ended December 31, 2019 and 2018, $33.8 million and $16.3 million, respectively, of previously capitalized contract costs were amortized and recognized as expense on the related contracts.

Contract liabilities include amounts owed under retainage provisions and billings in excess of costs and estimated earnings. The amount as reported on the Consolidated Balance Sheets ~~consists~~consisted of the following:



	As of December 31,		As of January 1,		As of December 31,
(in thousands)		2018		2018		2019		2018

Total contract liabilities	$	785,146	$	758,474	$	1,096,570	$	785,146

Retainage payable represents amounts invoiced to the Company by subcontractors where payments have been partially withheld pending the completion of certain milestones, other contractual conditions or upon the completion of the project. Generally, retainage payable is not remitted to subcontractors until the associated retainage receivable from customers is collected. As of December 31, ~~2018,~~2019, the amount of retainage ~~payables~~payable estimated by management to be ~~collected or~~ remitted beyond one year is approximately ~~24%~~28% of the balance.

Billings in excess of costs and estimated earnings represent the excess of contract billings to date over the amount of contract costs and profits (or contract revenue) recognized to date. The balance may fluctuate depending on the timing of contract billings and the recognition of contract revenue. Revenue recognized during the year ended December 31, 2019 and 2018 and included in the opening billings in excess of costs and estimated earnings balances totaled $479.6 million and $382.7 ~~million.~~million, respectively.

The Company’s provision for income taxes and effective tax rate for the year ended December 31, 2019 was significantly impacted by the goodwill impairment charge discussed in Note 6. Of the total goodwill impairment charge of $379.9 million, approximately $209.5 million pertained to goodwill that is not tax deductible and yielded permanent differences between book income and taxable income. For the year ended December 31, 2019, the Company recognized U.S. federal and state tax benefits totaling $49.4 million as a result of the impairment charge.

On December 22, 2017, the U.S. government enacted the ~~TCJA~~Tax Cuts and Jobs Act of 2017 (“TCJA”) which made broad and complex changes to the U.S. tax code that impact the Company’s financial statements, including, but not limited to, a permanent decrease in the corporate federal statutory income tax rate from 35% to 21%, effective January 1, 2018, and a one-time transition tax from the inclusion of foreign earnings. Future distributions from foreign subsidiaries, however, are no longer subject to federal income tax.

As a result of the TCJA, the Company recognized an income tax benefit of $53.3 million in 2017, primarily due to the remeasurement of deferred tax assets and liabilities based on the reduced corporate federal statutory income tax rate of 21%.

Prior to 2017, the Company did not provide for deferred income taxes or foreign withholding tax on basis differences in its non-U.S. subsidiaries that result from undistributed earnings which the Company had the intent and the ability to reinvest in its foreign operations. Due toSince the enactment of the TCJA, the Company no longer intends to permanently reinvest in its foreign subsidiaries. Consequently, the Company now provides deferred income taxes and foreign withholding taxes related to its foreign subsidiaries.

The Company’s policy is to record interest and penalties on unrecognized tax benefits as an element of income tax expense. The cumulative amounts related to interest and penalties are added to the total unrecognized tax liabilities on the balance sheet. The total amount of gross unrecognized tax benefits as of December 31, ~~2018~~2019 that, if recognized, would affect the effective tax rate is ~~$5.0~~$5.7 million. During 2018, the Company recognized a net decrease of $1.5 million in liabilities. The amount of gross unrecognized tax benefits as of December 31, 2017 was $6.5 million. During 2017, the Company recognized a net decrease of $1.1 million in liabilities. The amount of gross unrecognized tax benefits as of December 31, 2016 was $7.6 million. During 2016, the Company recognized a net increase of $4.0 million in liabilities. The Company does not expect any significant release of unrecognized tax benefits within the next twelve months.

The Company accounts for its uncertain tax positions in accordance with GAAP. The following is a reconciliation of the beginning and ending amounts of these unrecognized tax benefits for the three years ended December 31, ~~2018~~2019:

_____________________________________________________________________________________________________________

(a)As of December 31, ~~2018, 2017 and 2016,~~2019, accumulated impairment was $867.8 million.

The net change in the carrying amount of goodwill for the year ended December 31, 2019 was primarily due to a goodwill impairment charge of $379.9 million recorded in the second quarter of 2019. In connection with the preparation of its quarterly financial statements during the second quarter of 2019, the Company assessed the changes in circumstances that occurred during the quarter to determine whether it was more likely than not that the fair values of any of its reporting units were below their carrying amounts. While there was no single determinative event or factor, potential triggering events identified in the accounting guidance (ASC 350, Intangibles – Goodwill and Other) developed during the second quarter of 2019, which led the Company to conclude that, when considering the events and factors in totality, it was more likely than not that the fair values of each of its reporting units were below their carrying amounts. The triggering factors included:

The Company faced a declining stock price and observed a sustained decrease subsequent to the filing of the Company’s first quarter Form 10-Q on May 8, 2019, in both absolute terms and relative to its peers. Consistent with the average stock prices of companies in its peer group, the Company’s stock price had ~~$585.0 million~~been trending lower over several prior periods; however, during the second quarter of ~~goodwill allocated~~2019, the Company’s stock price dropped to a 52-week low while the average stock price of companies in its peer group increased. The Company believes that delays experienced in resolving certain claims and unapproved change orders, which when combined with the increased working capital needs and significant negative operating cash flows in the first quarter of 2019, has contributed significantly to the sustained decrease in the Company’s stock price;

The Company experienced significant negative operating cash flows from each of its reporting units in the first quarter of 2019, and that trend continued at the beginning of the second quarter; and

The Company’s debt rating was downgraded by a major credit rating agency on May 17, 2019.

As the Company determined that it was more likely than not that the fair values of its reporting units were below their carrying amounts, the Company performed an interim impairment test as of June 1, 2019 (the “Interim Test”) and, as described below, recognized a non-cash impairment loss totaling $379.9 million.

The decrease in the Company’s stock price reduced its total market capitalization and increased the implied control premium to a level beyond observable market-comparable data. As a result, when performing the Interim Test, the Company increased the discount rates and the projected investments in working capital compared to the assumptions used in the previous October 1, 2018 test, which extended the timing of certain expected future cash flows in the calculation of fair value under the income-based approach. The Company believes these changes were consistent with market participant inputs as reflected in the decrease in the Company’s market valuation at that time.

Consistent with the previous October 1, 2018 test, the Company utilized a weighted-average of (1) an income approach and (2) a market approach to determine the fair value of the Company and each of its reporting units for the Interim Test. The income approach was based on estimated present value of future cash flows for each reporting unit. The market approach was based on assumptions about how market data relates to each reporting unit. The weighting of these two approaches was based on their individual correlation to the economics of each reporting unit as impacted by factors such as the availability of comparable market data for each reporting unit.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Assessing impairment inherently involves management judgments as to the assumptions used to calculate fair value of the reporting units and the impact of market conditions on those assumptions. The key inputs that the Company uses in its assumptions to estimate the fair value of its reporting units under the income-based approach are as follows:

Weighted-average cost of capital (“WACC”), the risk-adjusted rate used to discount the projected cash flows;

Cash flows generated from existing work and new awards; and

Projected operating margins.

Expected future after-tax operating cash flows of each reporting unit are discounted to a present value using a risk-adjusted discount rate. Estimates of future cash flows require management to make significant assumptions concerning future operating performance including cash flows generated from existing work and new awards, projected operating margins, variations in the amount and timing of cash flows and the probability of achieving the estimated cash flows, as well as future economic conditions, which may differ from actual future cash flows. The discount rate, which is intended to reflect the risks inherent in future cash flow projections, used in estimating the present value of future cash flows, is based on estimates of the WACC of market participants relative to the reporting units. Financial and credit market volatility can directly impact certain inputs and assumptions used to develop the WACC.

To develop the cash flows generated from new awards and future operating margins, the Company tracks known prospects of significance for each of its reporting units and considers the estimated timing of when the work is expected to be bid, started and completed. The Company also gives consideration to its relationships with the prospective owners; the pool of competitors that are capable of performing large, complex work; business strategy; and the Company’s history of success in winning new work in each reporting unit. With regard to operating margins, the Company gives consideration to its historical reporting unit operating margins in the end markets that the prospective work opportunities are most significant, expected margins from existing work, current market trends in recent new work procurement, and business strategy.

The Company also estimated the fair value of its reporting units under a market-based approach by applying industry-comparable multiples of revenues and operating earnings to its reporting units’ revenues and operating earnings. The conditions and prospects of companies in the engineering and construction industry depend on common factors such as overall demand for services.

The Company believes that the discount rates, timing of cash flows and other inputs and assumptions used in the Interim Test were consistent with those that a market participant would use based on the events described above which occurred during the second quarter of 2019 and were reflective of the market assessment of the fair value of its reporting units at that time. In addition, the Company believes that its estimates and assumptions about future revenues and margin projections in the Interim Test were reasonable and consistent with the estimates and assumptions used in the annual goodwill impairment test as of October 1, 2018. As an additional step to corroborate the Interim Test results, the Company compared its implied control premium with those of recent comparable market transactions and concluded that the implied control premium was within the range of control premiums observed in prior industry-specific M&A transactions.

The assumption changes described above were relatively larger in the Specialty Contractors reporting unit than in the Civil or Building reporting units, as ~~follows: Civil, $415.3 million; Building, $13.5 million; and~~ Specialty Contractors ~~$156.2 million. The balances presented include historical accumulated~~had not met recent market expectations at the time of the Interim Test.

Subsequent to the Interim Test, the Company performed its annual impairment test in the fourth quarter of ~~$76.7 million for~~2019 using a weighted-average of an income and a market approach. These approaches utilize various valuation assumptions, and small changes to the assumptions could have a significant impact on the concluded fair value. Based on this assessment, the Company concluded goodwill was not impaired since the estimated fair value of the Civil reporting unit ~~and $411.3 million for the Building reporting unit.~~

exceeded its carrying value; therefore, no further adjustment to goodwill was necessary. In addition, asno events or circumstances have occurred since the annual test that would indicate any additional impairment of goodwill.

Intangible Assets

As of December 31, ~~2018~~2019 and ~~2017,~~2018, the Company had the following: (1) non-amortizable trade names with a carrying value of $50.4 million; (2) amortizable trade names with a gross carrying value of $51.1 million and accumulated amortization as of December 31, 2019 and 2018 of $21.3 million and ~~2017 of~~ $18.8 million, ~~and $16.3 million,~~ respectively; ~~and~~ (3) amortizable customer relationships with a gross carrying value of $23.2 million and accumulated amortization as of December 31, 2019 and 2018 ~~and 2017~~ of ~~$20.0~~$21.0 million and ~~$18.9~~$20.0 million, respectively; and (4) amortizable construction contract backlog with a gross carrying value as of December 31, 2019 and 2018 of $149.3 million and $73.7 million, respectively, and accumulated amortization as of December 31, 2019 and 2018 of $76.4 million and $73.7, respectively. The increase in amortizable construction contract backlog of $75.6 million is due to the acquisition of an additional interest in a joint venture, as discussed in Note 13.

Amortization expense related to amortizable intangible assets was $6.2 million and $3.5 million for ~~each of~~ the years ended December 31, 2019 and 2018, ~~2017 and 2016.~~ respectively. Future amortization expense related to amortizable intangible assets for the years 2020, 2021 and 2022 will be approximately ~~$3.5~~$31.2 million, ~~per year for the years 2019 through 2021, $2.6~~$31.1 million ~~for the year 2022~~and $20.2 million, respectively, and $2.5 million for the ~~year 2023.~~years 2023 and 2024.

The weighted-average amortization period for amortizable trade names, ~~and~~ customer relationships and construction contract backlog is approximately 20 years, ~~and~~ 12 years and 3 years, respectively.

In conjunction with its Interim Test for goodwill during the second quarter of 2019, the Company also evaluated its non-amortizable trade names for potential impairment due to the second quarter triggering factors related to goodwill mentioned above. The Company performed its interim impairment test by comparing the carrying value of its indefinite-lived intangible assets to their calculated fair value, which is determined by the income approach (relief from royalty method). This income-based valuation approach involves similar key assumptions to the goodwill impairment analysis discussed above. The interim impairment test performed in the second quarter of 2019 resulted in an estimated fair value for the non-amortizable trade names that substantially exceeded their respective net book values; therefore, no impairment charge was necessary for the second quarter. While the key assumptions used in the impairment test of the non-amortizable trade names are similar to those used in the evaluation of goodwill, historically, the headroom (the excess of calculated fair value over carrying value) has been relatively higher for non-amortizable trade names than for goodwill. Unlike goodwill, trade names possess inherent value based on market perception which is valued considering the cost savings available through ownership and the avoidance of paying royalties associated with revenue generation. The discounted value is not impacted by cash flow related assumptions such as working capital investment. Consequently, goodwill was impaired while the non-amortizable trade name intangible assets were not.

F-21

~~Table~~The Company also performed an annual impairment assessment of ~~Contents~~its non-amortizable trade names in the fourth quarter of 2019 using a qualitative approach to determine whether conditions existed to indicate that it is more likely than not that the fair value of trade names is less than their carrying values. Based on this assessment, the Company concluded that it was more likely than not that the fair value of the non-amortizable trade names was greater than their carrying values, and therefore a quantitative analysis was not required.

2017 Senior Notes

On April 20, 2017, the Company issued $500 million in aggregate principal amount of 6.875% Senior Notes due 2025 (the “2017 Senior Notes”) in a private placement offering. Interest on the 2017 Senior Notes is payable in arrears semi-annually in May and November of each year, beginning in November 2017.

Prior to May 1, 2020, the Company may redeem the 2017 Senior Notes at a redemption price equal to 100% of their principal amount plus a “make-whole” premium described in the indenture. In addition, prior to May 1, 2020, the Company may redeem up to 40% of the original aggregate principal amount of the notes at a redemption price of 106.875% of their principal amount with the proceeds received by the Company from any offering of the Company’s equity. After May 1, 2020, the Company may redeem the 2017 Senior Notes at specified redemption prices described in the indenture. Upon a change of control, holders of the 2017 Senior Notes may require the Company to repurchase all or part of the 2017 Senior Notes at 101% of the principal amount thereof, plus accrued and unpaid interest to the redemption date.

The 2017 Senior Notes are senior unsecured obligations of the Company and are guaranteed by substantially all of the Company’s existing and future subsidiaries that also guarantee obligations under the Company’s 2017 Credit Facility, as defined below. In addition, the indenture for the 2017 Senior Notes provides for customary covenants, including events of default and restrictions on the payment of dividends and share repurchases.

2017 Credit Facility

On April 20, 2017, the Company entered into a credit agreement (the “2017 Credit Facility”) with SunTrust Bank, now known as Truist Bank, as Administrative Agent, Swing Line Lender and L/C Issuer and a syndicate of other lenders. The 2017 Credit Facility provides for a $350 million revolving credit facility (the “2017 Revolver”) and a sublimit for the issuance of letters of credit and swingline loans up to the aggregate amount of $150 million and $10 million, respectively, both maturing on April 20, 2022 unless any of the Convertible Notes, as defined below, are outstanding on December 17, 2020, in which case all such borrowings will mature on December 17, 2020, ~~(subject to certain further exceptions). In addition,~~provided that (i) if the Convertible Notes are refinanced in full with the proceeds of permitted refinancing indebtedness in accordance with the terms of the 2017 Credit Facility, the maturity date for the 2017 Credit Facility will remain April 20, 2022 and (ii) if the Company issues “New Convertible Notes” (as defined in the 2017 Credit Facility), the maturity date for the 2017 Credit Facility will be the earlier of (x) April 20, 2022 or December 17, 2020 if Convertible Notes are outstanding on December 17, 2020 and (y) 90 days prior to the maturity date for such New Convertible Notes. The 2017 Credit Facility also permits additional borrowings in an aggregate amount of $150 million, which can be in the form of increased capacity on the 2017 Revolver or the establishment of one or more term loans.

Borrowings under the 2017 Revolver bear interest, at the Company’s option, at a rate equal to (a) the London Interbank Offered Rate (“LIBOR”) plus a margin of between 1.50% and 3.00% or (b) a base rate (determined by reference to the highest of (i) the administrative agent’s prime lending rate, (ii) the federal funds effective rate plus 50 basis points, (iii) the LIBOR rate for a one-month interest period plus 100 basis points and (iv) 0%), plus a margin of between 0.50% and 2.00%, in each case based on the Consolidated Leverage Ratio (as defined in the 2017 Credit Facility). In addition to paying interest on outstanding principal under the 2017 Credit Facility, the Company will pay a commitment fee to the lenders under the 2017 Revolver in respect of the unutilized commitments thereunder. The Companywill pay customary letter of credit fees. If an event of default occurs and is continuing, the otherwise applicable margin and letter of credit fees will be increased by 2% per annum. The weighted-average annual interest rate on borrowings under the 2017 Revolver was approximately ~~4.77%~~4.96% during the year ended December 31, ~~2018.~~2019.

The 2017 Credit Facility contains customary covenants for credit facilities of this type, including maximum consolidated leverage ratios ranging from 4.00:1.00 to 3.25:1.00 over the life of the facility and a minimum consolidated fixed charge coverage ratio of 1.25:1.00. On May 7, 2019, certain provisions of the 2017 Credit Facility were amended, including setting the maximum leverage ratio at 3.50:1.00 for the remainder of its term, thus eliminating the step down from 3.50:1:00 to 3.25:1.00. Substantially all of the Company’s subsidiaries unconditionally guarantee the obligations of the Company under the 2017 Credit Facility; additionally, the obligations are secured by a lien on all personal property of the Company and its subsidiaries guaranteeing these obligations.

As of December 31, ~~2018,~~2019, there was ~~$309~~$236 million available under the 2017 Revolver, and the Company had not utilized the 2017 Credit Facility for letters of credit.

Convertible Notes

On June 15, 2016, the Company issued $200 million of 2.875% Convertible Senior Notes due June 15, 2021 (the “Convertible Notes”) in a private placement offering. The Convertible Notes are unsecured obligations of the Company and do not contain any financial covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities by the Company. The Convertible Notes bear interest at a rate of 2.875% per year, payable in cash semi-annually in June and December.

To account for the Convertible Notes, the Company applied the provisions of ASC 470-20, Debt with Conversion and Other Options (“ASC 470-20”). ASC 470-20 requires issuers of certain convertible debt instruments that may be settled in cash upon conversion to separately account for the liability (debt) and equity (conversion option) components of the instrument in a manner that reflects the issuer’s nonconvertible debt borrowing rate. This is done by allocating the proceeds from issuance to the liability component based on the fair value of the debt instrument excluding the conversion feature, with the residual allocated to the equity component and classified in additional paid in capital. The $46.8 million difference between the principal amount of the Convertible Notes ($200.0 million) and the proceeds initially allocated to the liability component ($153.2 million) is treated as a discount on the Convertible Notes. This difference is being amortized as non-cash interest expense using the interest method, as shown below under Interest Expense. The equity component, however, is not subject to amortization nor subsequent remeasurement.

In addition, ASC 470-20 requires that the debt issuance costs associated with a convertible debt instrument be allocated between the liability and equity components in proportion to the allocation of the debt proceeds between these two components. The debt issuance costs attributable to the liability component of the Convertible Notes ($5.1 million) are also treated as a discount on the Convertible Notes and amortized as non-cash interest expense. The debt issuance costs attributable to the equity component ($1.5 million) were netted with the equity component and are not amortized.

~~Several matters are in~~A description of the ~~litigation and dispute resolution processes that include characteristics which management consider to be~~material pending legal proceedings, other than ordinary routine ~~contract performance related issues. The following discussion provides a background and current status of such material matters.~~

~~Long Island Expressway/Cross Island Parkway Matter~~

The Company reconstructed the Long Island Expressway/Cross Island Parkway Interchange (“LIE” Project) for the New York State Department of Transportation (“NYSDOT”). The $130 million project was substantially complete in January 2004 and was accepted by NYSDOT as complete in February 2006. The Company incurred significant added costs in completing its work and suffered extended schedule costs due to numerous design errors, undisclosed utility conflicts, lack of coordination with local agencies and other interferences for which the Company believes NYSDOT is responsible.

~~In March 2011, the Company opened a case with the New York State Court of Claims against NYSDOT related~~litigation incidental to the LIE Project. In May 2011, NYSDOT filed a motion to dismiss the Company’s claim on the grounds that the Company had not provided required documentation for project closeout and filing of a claim. In September 2011, the Company reached agreement on final payment with the Comptroller’s Office on behalf of NYSDOT, which resulted in an amount of $0.5 million payable to the Company and formally closed out the project allowing the Company to re-file its claim. In March 2012, the Company filed its formal Verified Claim seeking $50.7 million in damages. In May 2012, NYSDOT served its answer and asserted counterclaims in the amount of $151 million alleging fraud in the inducement and punitive damages related to alleged violations of the disadvantaged business ~~enterprise (“DBE”) requirements for the project. The Court subsequently ruled that NYSDOT’s counterclaims may only be asserted~~is as a defense and offset to the Company’s claims and not as affirmative claims. In November 2014, the Appellate Division First Department affirmed the dismissal of NYSDOT’s affirmative counterclaims. In June 2018, following additional summary judgment motions, the Court granted the Company’s motion to dismiss NYSDOT’s affirmative defenses, which eliminated the use of NYSDOT’s counterclaim of $151 million as a defense to the claims of the Company. In October 2018, NYSDOT filed a notice of appeal. A trial date for the appeal has not been set.follows:

Management has made an estimate of the total anticipated recovery on this project, and such estimate is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the consolidated financial statements at that time.

~~Fontainebleau Matter~~

Desert Mechanical, Inc. (“DMI”) and Fisk Electric Company (“Fisk”), wholly owned subsidiaries of the Company, were subcontractors on the Fontainebleau project located in Las Vegas, Nevada, a hotel/casino complex with approximately 3,800 rooms (the “Project”). In June 2009, the owners of the Project filed for bankruptcy protection, under Chapter 11 of the U.S. Bankruptcy Code, in the Southern District of Florida.

DMI and Fisk recorded mechanic’s liens against the Project totaling approximately $44 million, for unpaid labor, materials and equipment it furnished to the Project. Other unaffiliated contractors, subcontractors and suppliers also recorded mechanic’s liens against the Project, subjecting the property to approximately $550 million in total lien claims by the various lien claimants who furnished labor, materials and equipment to the Project (the “Statutory Lienholders”). In June 2009, DMI filed suit against Turnberry West Construction, Inc., the general contractor, in the Eighth Judicial District Court, Clark County, Nevada, and in May 2010, the court entered an order in favor of DMI for approximately $45 million.

In January 2010, the Bankruptcy Court approved the sale of the Property to Icahn Nevada Gaming Acquisition, LLC for approximately $150 million. Certain Project lenders (the “Lenders”) who had recorded deeds of trust as security interests in the property which far exceeded the sale proceeds, filed suit against the Statutory Lienholders, including DMI and Fisk, alleging that all mechanic’s liens were subordinate to the Lenders’ deeds of trust against the property. The Nevada Supreme Court ruled in October 2012 that under Nevada Law, the mechanic’s lien claims had priority over a portion of the deeds of trust, but not all of them.

In October 2013, a comprehensive settlement agreement was reached by and among the Statutory Lienholders and the Lenders to divide the Sale Proceeds such that the Statutory Lienholders would receive approximately $85 million of the sale proceeds (the “Net Statutory Lienholder Proceeds”) and the Lenders would receive the balance. The Bankruptcy Court appointed a mediator to facilitate a settlement between the Statutory Lienholders as to how the Net Statutory Lienholder Proceeds would be distributed, but after engaging in numerous mediation sessions spanning several years, the parties were unable to reach a resolution. DMI filed a motion seeking permission from the Bankruptcy Court to file an action in Nevada to enforce its lien rights against the Net Statutory Lienholder Proceeds, and the motion was granted. Pursuant to that order, litigation involving all Statutory Lienholders was commenced at the end of November 2017 (the “Nevada Action”).

A determination of each Statutory Lienholder’s rights against the Net Statutory Lienholder Proceeds in the Nevada Action is expected by May 2019, with a pro rata distribution of those monies to follow shortly thereafter.

Management has made an estimate of the total anticipated recovery on this Project, and such estimate is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the consolidated financial statements at that time.

~~Westgate Planet Hollywood Matter~~

Tutor-Saliba Corporation (“TSC”), a wholly owned subsidiary of the Company, was contracted to construct a timeshare development project in Las Vegas, which was substantially completed in December 2009. The Company’s claims against the owner, Westgate Planet Hollywood Las Vegas, LLC (“WPH”), relate to unresolved owner change orders and other claims. The Company filed a lien on the project in the amount of $23.2 million and filed its complaint with the District Court, Clark County, Nevada. Several subcontractors have also recorded liens, some of which have been released by bonds and some of which have been released as a result of subsequent payment. WPH has posted a mechanic’s lien release bond for $22.3 million.

WPH filed a cross-complaint alleging non-conforming and defective work for approximately $51 million, primarily related to alleged defects, misallocated costs and liquidated damages. WPH revised the amount of their counterclaims to approximately $45 million.

Following multiple post-trial motions, final judgment was entered in this matter on March 20, 2014. TSC was awarded total judgment in the amount of $19.7 million on its breach of contract claim, which includes an award of interest up through the date of judgment, plus attorney’s fees and costs. WPH was awarded total judgment in the amount of $3.1 million on its construction defect claims, which includes interest up through the date of judgment. WPH and its Sureties filed a notice of appeal. TSC filed a notice of appeal on the defect award. In July 2014, the District Court ordered WPH to post an additional supersedeas bond on appeal, in the amount of

~~NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)~~

$1.7 million, in addition to the lien release bond of $22.3 million, which increases the security up to $24.0 million. In May 2017, the Nevada Supreme Court issued its ruling on the appeal by WPH and its Sureties. With only minor adjustments, the Nevada Supreme Court affirmed the District Court’s judgment, and following further proceedings in the District Court, the anticipated final recovery to the Company is estimated to exceed $20 million, including interest and recovery of certain attorneys’ fees and costs of which the Company collected more than $16 million in 2017. In December 2017 and in January 2018, the District Court issued several post-appeal orders confirming its previous rulings. Some of those matters have been appealed and are expected to be resolved in the first half of 2019. Once resolved, TSC will seek an order from the District Court seeking the remaining $4 million in interest and fees associated with the matter.

The Company does not expect the ultimate resolution of this matter to have a material effect on its consolidated financial statements. Management has made an estimate of the total anticipated recovery on this project and such estimate is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the consolidated financial statements at that time.

Five Star Electric Matter

In the third quarter of 2015, Five Star Electric Corp. (“Five Star”), a wholly owned subsidiary of the Company that was acquired in 2011, entered into a tolling agreement (which has since expired) related to an ongoing investigation being conducted by the United States Attorney’s Office for the Eastern District of New York (“USAO EDNY”). Five Star has been cooperating with the USAO EDNY since late June 2014, when it was first made aware of the investigation, and has provided information requested by the government related to its use of certain minority-owned, women-owned, small and disadvantaged business enterprises and certain of Five Star’s employee compensation, benefit and tax practices.

As of December 31, ~~2018,~~2019, the Company cannot predict the ultimate outcome of the investigation and cannot reasonably estimate the potential loss or range of loss that Five Star or the Company may incur or the impact of the results of the investigation on Five Star or the Company.

Alaskan Way Viaduct Matter

In January 2011, Seattle Tunnel Partners (“STP”), a joint venture between Dragados USA, Inc. and the Company, entered into a design-build contract with the Washington State Department of Transportation (“WSDOT”) for the construction of a large diameter bored tunnel in downtown Seattle, King County, Washington to replace the Alaskan Way Viaduct, also known as State Route 99. The Company has a 45% interest in STP.

The construction of the large diameter bored tunnel required the use of a tunnel boring machine (“TBM”). In December 2013, the TBM struck a steel pipe, installed by WSDOT as a well casing for an exploratory well. The TBM was significantly damaged and was required to be ~~shut down for repair.~~repaired. STP has asserted that the steel pipe casing was a differing site condition that WSDOT failed to properly disclose. The Disputes Review Board mandated by the contract to hear disputes issued a decision finding the steel casing was a Type I (material) differing site condition. WSDOT has not accepted that finding.

The TBM was insured under a Builder’s Risk Insurance Policy (the “Policy”) with Great Lakes Reinsurance (UK) PLC and a consortium of other insurers (the “Insurers”). STP submitted the claims to the Insurers and requested interim payments under the Policy. The Insurers refused to pay and denied coverage. In June 2015, STP filed a lawsuit in the King County Superior Court, State of Washington ~~(“Washington Superior Court”)~~ seeking declaratory relief concerning contract interpretation, as well as damages as a result of the Insurers’ breach of their obligations under the terms of the Policy. STP is also asserting extra-contractual and statutory claims against the Insurers. WSDOT is deemed a plaintiff since WSDOT is an insured under the Policy and had filed its own claim for damages. Hitachi Zosen (“Hitachi”), the manufacturer of the TBM, has also joined the case as a plaintiff for costs incurred to repair the damages to the TBM.

In September 2018, rulings received on pre-trial motions effectively limited potential recovery under the Policy for STP, WSDOT and Hitachi. However, on December 19, 2018, the Court of Appeal granted the Company’s request for a discretionary appeal of those rulings. The appeal is expected to be heard in mid to late 2020. STP submitted damages to the ~~second half~~Insurers in the King County lawsuit in the amount of ~~2019. To~~$532 million. STP is also seeking these damages from WSDOT related to the ~~extent we are unable to recover damages under~~pipe-strike by the ~~Policy, we can still seek recovery against WSDOT and Hitachi.~~TBM in a related lawsuit in Thurston County (see following paragraph).

In March 2016, WSDOT filed a complaint against STP in Thurston County Superior Court for breach of contract alleging STP’s delays and failure to perform, seeking $57.2 million in damages and seeking declaratory relief concerning contract interpretation. STP filed its answer to WSDOT’s complaint and filed a counterclaim against WSDOT and ~~Hitachi. Trial~~Hitachi, as the TBM designer, seeking damages of $667 million. On October 3, 2019, STP and Hitachi entered into a settlement agreement which caused the release and dismissal of claims that STP and Hitachi had against each other. The jury trial between STP and WSDOT commenced on October 7, 2019 and concluded on December 13, 2019, with a jury verdict in favor of WSDOT awarding them $57.2 million in damages. Judgment was entered on January 10, 2020, and a notice of appeal was filed by STP on January 17, 2020.

The Company recorded the impact of the jury verdict during the fourth quarter of 2019, resulting in a pre-tax charge of $166.8 million. The charge includes a pre-tax accrual of $25.7 million (which is ~~scheduled~~the Company’s 45% proportionate share of the $57.2 million in damages awarded by the jury to WSDOT). Payment of damages will only be made if the adverse verdict is upheld on appeal, as the payment is secured by a bond for the course of the appeal. Other than the possible future payment in cash of $25.7 million in damages, the charge is for non-cash write-downs primarily related to the costs and estimated earnings in excess of billings and receivables that the Company previously recorded to reflect its expected recovery in this case.

With respect to STP’s direct and indirect claims against the Insurers, management has included in receivables an estimate of the total anticipated recovery concluded to be probable.

George Washington Bridge Bus Station Matter

In August 2013, Tutor Perini Building Corporation (“TPBC”) entered into a contract with the George Washington Bridge Bus Station Development Venture, LLC (the “Developer”) to renovate the George Washington Bridge Bus Station, a mixed-use facility owned by the Port Authority of New York and New Jersey that serves as a transit facility and retail space. The $100 million project experienced significant design errors and associated delays, resulting in damages to TPBC and its subcontractors, including WDF and Five Star, wholly owned subsidiaries of the Company. The project reached substantial completion on May 16, 2017.

On February 26, 2015, the Developer filed a demand for arbitration, subsequently amended, seeking $30 million in alleged damages and declaratory relief that TPBC’s requests for additional compensation are invalid due to lack of notice. TPBC denied the Developer’s claims and filed a counterclaim in March 2018. TPBC seeks in excess of $113 million in the arbitration, which includes unpaid contract balance claims, the return of $29 million retained by the Developer in alleged damages, as well as extra work claims, pass-through claims and delay claims.

Hearings on the merits commenced on September 24, 2018 before the arbitration panel, and were expected to continue over various weeks through March 2020. On April 15, 2019, the counsel for the Developer withdrew from the case, which resulted in further delays to the proceedings. On June 4, 2019, the arbitration panel, as confirmed by the U.S. District Court in the Southern District of New York, issued a writ of attachment for $23 million of the $29 million discussed above. On October 7, 2019, the Developer filed for bankruptcy protection in the Southern District of New York under Chapter 11 of the Bankruptcy Code. The filing for bankruptcy stayed the pending arbitration proceedings. TPBC appeared in the bankruptcy proceedings on October 8, 2019 and filed a Proof of Claim in the amount of $113 million on December 13, 2019.

Separately, on July 2, 2018, TPBC filed a lawsuit against the Port Authority of New York and New Jersey, as owner of the project, and STV Incorporated, as designer, seeking the same $113 million in damages. On January 13, 2020, the Court dismissed STV Incorporated from the case. That lawsuit is proceeding against the Port Authority of New York and New Jersey.

On January 27, 2020, the Company filed separate litigation in the United States District Court for the Southern District of New York in which the Company asserted claims against individual owners of the Developer for their wrongful conversion of project funds and against certain lenders that received interest payments from project funds and other amounts earmarked to pay the contractors.

As of December 31, ~~2018,~~2019, the Company has concluded that the potential for a material adverse financial impact due to the ~~Insurers’ denial of coverage and WSDOT’s legal actions~~Developer’s claims is ~~neither probable nor remote, and the potential loss or range of loss is not reasonably estimable.~~remote. With respect to ~~STP’s~~TPBC’s claims against the ~~Insurers, WSDOT~~Developer and ~~Hitachi,~~the Port Authority of New York and New Jersey, management has ~~included~~made an estimate of the total anticipated recovery on this project, and such estimate is included in revenue recorded to date.

9. Leases

The Company leases certain office space, construction and office equipment, vehicles and temporary housing generally under non-cancelable operating leases. Leases with an initial term of one year or less are not recorded on the balance sheet, and the Company generally recognizes lease expense for these leases on a straight-line basis over the lease term. As of December 31, 2019, the Company’s operating leases have remaining lease terms ranging from less than one year to ~~be both probable~~10 years, some of which include options to renew the leases. The exercise of lease renewal options is generally at the Company’s sole discretion. The Company’s leases do not contain any material residual value guarantees or material restrictive covenants.

The Company determines if an arrangement is a lease at inception. Operating lease ROU assets are included in other assets, while current and ~~reliably estimable,~~long-term operating lease liabilities are included in ~~receivables or costs~~accrued expenses and ~~estimated earnings~~other current liabilities, and other long-term liabilities, respectively, on the Consolidated Balance Sheet as of December 31, 2019. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The present value of future lease payments are discounted using either the implicit rate in ~~excess of billings recorded to date. To~~ the ~~extent new facts become~~lease, if known, or the ~~final recoveries vary~~Company’s incremental borrowing rate for the specific lease as of the lease commencement date. The ROU asset is also adjusted for any prepayments made or incentives received. The lease terms include options to extend or terminate the lease only to the extent it is reasonably certain any of those options will be exercised. Lease expense is recognized on a straight-line basis over the lease term. The Company accounts for lease components (e.g., fixed payments) separate from the ~~estimate,~~non-lease components (e.g., common-area maintenance costs).The Company does not have any material financing leases.

10. Other Income, Net

On May 31, 2017, the Company entered into a settlement agreement with Merrill Lynch, Pierce, Fenner & Smith Incorporated (“Merrill Lynch”), as successor in interest to Banc of America Securities LLC and Bank of America, N.A. (collectively “BofA”), to resolve the pending litigation between the Company and Merrill Lynch. The litigation, which was filed by the Company in 2011, related to the Company’s purchase of certain auction-rate securities from BofA.

On June 6, 2017, the Company received the $37.0 million cash settlement payment agreed to in the settlement agreement, and the pending litigation was dismissed with prejudice. Neither party made any admission of liability or wrongdoing, and the settlement agreement includes mutual releases of all claims and liabilities related to the subject matter of the pending litigation.

The Company recognized the settlement as a gain and reported it as a component of other income, net in its Consolidated Statement of ~~Income~~Operations for the year ended December 31, 2017.

11. Share-Based Compensation

On April 10, 2018, the Company adopted the Tutor Perini Corporation Omnibus Incentive Plan (the “Current Plan”), which was approved by the Company’s shareholders on May 23, 2018. The Current Plan effected the merger of the Company’s Amended and Restated Tutor Perini Corporation Long-Term Incentive Plan, as amended and restated on October 2, 2014 (the “2014 Plan”) and the Tutor Perini Corporation Incentive Compensation Plan adopted on April 3, 2017 (the “2017 Plan,” together with the 2014 Plan and the Current Plan, the “Plans”). The Current Plan provides for various types of share-based grants, including restricted and unrestricted stock units and stock options. Restricted and unrestricted stock units give the holder the right to exchange their stock units for shares of the Company’s common stock on a one-for-one basis. Stock options give the holder the right to purchase shares of the Company’s common stock subsequent to the vesting date at a defined exercise price. A stock option exercise price must be equal to or greater than the fair value of the Company’s common stock on the date of the award. Restricted stock units and stock options are usually subject to certain service and performance conditions as well as other restrictions. The term for stock options is limited to 10 years from the ~~date of grant.~~award date. As of December 31, ~~2018,~~2019, there were ~~800,667~~1,241,879 shares of common stock available for grant under the Company’s Current Plan. As of December 31, ~~2018,~~2019, the Plans had an aggregate of ~~4,732,044~~4,144,015 of restricted stock units and stock options from outstanding, historical awards that either have not vested or have vested but have not been exercised. Any awards that were granted under the 2014 Plan or the 2017 Plan that are forfeited, cancelled or held back for net settlement will become available to be issued under the Current Plan.

The terms of the Plans give the Company the right to settle the vesting of share-based grants in cash or shares. During the ~~year~~years ended December 31, 2019 and 2018, the Company did ~~not~~0t settle any awards in cash. During the year ended December 31, 2017, the Company paid approximately $0.6 million to settle share-based awards.

Many of the awards issued under the Plans contain separate tranches, each for a separate performance period and each with a performance target to be established subsequent to the award date; accordingly, the tranches are accounted for under ASC 718, Stock Compensation (“ASC 718”) as separate grants, with the grant date being the date the performance targets for a given tranche are established and communicated to the grantee. Similarly, for these awards, compliance with the requirements of the Plans is also based on the number of units granted in a given year, as determined by ASC 718, rather than the number of units awarded in a given year. As a result, as of December 31, ~~2018,~~2019, the Company had outstanding awards with ~~160,000~~75,000 restricted stock units and ~~160,000~~75,000 stock options that had not been granted yet. These units will be granted in ~~2019 and~~ 2020 when the performance targets for those respective years are established.

Unrestricted stock units vest immediately upon grant and are converted to shares of the Company’s stock on a one-for-one basis. The fair value of unrestricted stock units issued during 2019, 2018 ~~2017~~ and ~~2016~~2017 was approximately $1.5 million, $2.5 million and $2.6 million, ~~and $1.4 million,~~ respectively.

The ~~2,943,044~~2,279,015 outstanding stock options as of December 31, ~~2018~~2019 had an intrinsic value of ~~$2.5~~$0.9 million and a weighted-average remaining contractual life of ~~4.8~~5.5 years. Of those outstanding options: (1) ~~2,034,044~~1,509,015 were exercisable with an intrinsic value of ~~$2.5~~$0.9 million, a weighted-average exercise price of ~~$19.42~~$19.69 per share and a weighted-average remaining contractual life of ~~3.1~~4.1 years; (2) ~~909,000~~770,000 have been granted but have not vested with no intrinsic value, a weighted-average exercise price of ~~$23.92~~$22.44 per share and a weighted-average remaining contractual life of ~~8.5~~8.4 years. Of the granted but unvested options, ~~876,750,~~770,000, are expected to vest.

The fair value of restricted and unrestricted stock units is based on the closing price of the Company’s common stock on the New York Stock Exchange on the date of the grant and the fair value of stock options is based on the Black-Scholes model. ~~For certain~~Certain performance-based awards ~~containing~~contain market condition components tied to the Company’s total shareholder return in relation to its peer companies, as calculated over a multi-year performance period (“TSR awards”). The fair value onof the ~~grant date~~TSR awards is determined using a Monte Carlo simulation model. Significant assumptions used in this simulation model include the Company’s expected volatility, a risk-free rate based on U.S. Treasury yield curve rates with maturities consistent with the performance period, and the volatilities for each of the Company’s peers. The ultimate payout on TSR awards is determined at the end of the performance period and will vary based on actual total shareholder return performance results. Compensation expense related to the TSR awards is recognized regardless of whether the market condition is satisfied, provided that the requisite service period has been completed.

12. Employee Benefit Plans

Defined Benefit Pension Plan

The Company has a defined benefit pension plan that covers certain of its executive, professional, administrative and clerical employees, subject to certain specified service requirements. The pension plan is noncontributory and benefits are based on an employee’s years of service and “final average earnings,” as defined by the pension plan. The pension plan provides reduced benefits for early retirement and takes into account offsets for social security benefits. The Company also has an unfunded supplemental retirement plan (“Benefit Equalization Plan”) for certain employees whose benefits under the defined benefit pension plan were reduced because of compensation limitations under federal tax laws. Effective June 1, 2004, all benefit accruals under the Company’s pension plan and Benefit Equalization Plan were frozen; however, the current vested benefit was preserved. Pension disclosure as presented below includes aggregated amounts for both of the Company’s plans, except where otherwise indicated.

The Company historically has used the date of its year-end as its measurement date to determine the funded status of the pension plan.

The long-term investment goals of the Company’s pension plan are to manage the assets in accordance with the legal requirements of all applicable laws; produce investment returns which maximize return within reasonable and prudent levels of risks; and achieve a fully funded status with regard to current pension liabilities. Some risk must be assumed in order to achieve the investment goals. Investments with the ability to withstand short and intermediate term variability are considered and some interim fluctuations in market value and rates of return are tolerated in order to achieve the pension plan’s longer-term objectives.

The pension plan’s assets are managed by a third-party investment manager. The Company monitors investment performance and risk on an ongoing basis.

The discount rate used in determining the accumulated post-retirement benefit obligation was 3.1% as of December 31, 2019 and 4.1% as of December 31, ~~2018 and 3.5% as of December 31, 2017.~~2018. The discount rate used for the accumulated post-retirement obligation was derived using a blend of U.S. Treasury and high-quality corporate bond discount rates.

The expected long-term rate of return on assets assumption was 5.8% for 2019 and 6.0% for ~~both 2018 and 2017.~~2018. The expected long-term rate of return on assets assumption was developed considering forward looking capital market assumptions and historical return expectations for each asset class assuming the plans’ target asset allocation and full availability of invested assets.

Closely held fund strategies seek to capitalize on inefficiencies identified across different asset classes or markets and include long-short equity and long equity, event-driven, multi-strategy and distressed credit.

Plan assets were measured at fair value. Registered investment companies are public investment vehicles valued using the Net Asset Value (“NAV”) of shares held by the pension plan at year-end. Equity and fixed income funds are valued based on quoted market

Multiemployer Plans

In addition to the Company’s defined benefit pension and contribution plans discussed above, the Company participates in multiemployer pension plans for its union construction employees. Contributions are based on the hours worked by employees covered under various collective bargaining agreements. Under the Employee Retirement Income Security Act, a contributor to a multiemployer plan is only liable for its proportionate share of a plan’s unfunded vested liability upon termination, or withdrawal from a plan. The Company currently has no intention of withdrawing from any of the multiemployer pension plans in which it participates and, therefore, has not recognized a liability for its proportionate share of any unfunded vested liabilities associated with these plans.

Upon the occurrence of certain events outlined in ASC 810, the ~~company~~Company reassesses its initial determination of whether the joint venture is a VIE.

ASC 810 also requires the Company to determine whether it is the primary beneficiary of the VIE. The Company concludes that it is the primary beneficiary and consolidates the VIE if the Company has both (a) the power to direct the economically significant activities of the VIE and (b) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. The Company considers the contractual agreements that define the ownership structure, distribution of profits and losses, risks, responsibilities, indebtedness, voting rights and board representation of the respective parties in determining if the Company is the primary beneficiary. The Company also considers all parties that have direct or implicit variable interests when determining whether it is the primary beneficiary. In accordance with ASC 810, management’s assessment of whether the Company is the primary beneficiary of a VIE is performed continuously.

As of December 31, 2019, the Company had unconsolidated VIE-related current assets and liabilities of $1.5 million and $1.4 million, respectively, included in the Company’s Consolidated Balance Sheet. As of December 31, 2018, the Company had unconsolidated VIE-related current assets and liabilities of $4.0 million and $3.8 million, respectively, ~~included in the Company’s Consolidated Balance Sheet. As of December 31, 2017, the Company had unconsolidated VIE-related current assets and liabilities each of $0.8 million,~~ included in the Company’s Consolidated Balance Sheet. The Company’s maximum exposure to loss as a result of its investments in unconsolidated VIEs is typically limited to the aggregate of the carrying value of the investment and future funding commitments. There were no future funding requirements for the unconsolidated VIEs as of December 31, ~~2018.~~2019.

As of December 31, 2019, the Company’s Consolidated Balance Sheet included current and noncurrent assets of $365.0 million and $52.0 million, respectively, as well as current liabilities of $556.1 million related to the operations of its consolidated VIEs. As of December 31, 2018, the Company’s Consolidated Balance Sheet included current and noncurrent assets of $173.9 million and $51.5 million, respectively, as well as current liabilities of $319.9 million related to the operations of its consolidated VIEs. As of December 31, 2017, the Company’s Consolidated Balance Sheet included current and noncurrent assets of $95.5 million and $11.6 million, respectively, as well as current liabilities of $140.7 million related to the operations of its consolidated VIEs.

Below is a discussion of some of the Company’s more significant or unique VIEs.

The Company established a joint venture to construct the Purple Line Extension Section 2 ~~Extension project, a $1.4 billion~~(Tunnels and Stations) and Section 3 (Stations) mass-transit ~~project~~projects in Los Angeles, ~~California.~~California with a combined value of approximately $2.8 billion. The Company has a 75% interest in the joint venture with the remaining 25% held by O&G Industries, Inc. (“O&G”). The joint venture was initially financed with contributions from the partners and, per the terms of the joint venture agreement, the partners may be required to provide additional capital contributions in the future. The Company has determined that this joint venture is a VIE for which the Company is the primary beneficiary.

The Company also established a joint venture with Parsons Corporation (“Parsons”) to construct the Newark Liberty International Airport Terminal One project, a $1.4 billion transportation infrastructure project in Newark, New Jersey. The Company has an 80% interest in the joint venture with the remaining 20% held by Parsons. The joint venture was initially financed with contributions from the partners and, per the terms of the joint venture agreement, the partners may be required to provide additional capital contributions in the future. The Company has determined that this joint venture is a VIE for which the Company is the primary beneficiary.

~~14.~~15. Business Segments

The Company offers general contracting, pre-construction planning and comprehensive project management services, including planning and scheduling of manpower, equipment, materials and subcontractors required for the timely completion of a project in accordance with the terms and specifications contained in a construction contract. The Company also offers self-performed construction services: site work, concrete forming and placement, steel erection, electrical, mechanical, plumbing, and HVAC (heating, ventilation and air conditioning). As described below, the Company’s business is conducted through ~~three~~3 segments: Civil, Building and Specialty Contractors. These segments are determined based on how the Company’s Chairman and Chief Executive Officer (chief operating decision maker) aggregates business units when evaluating performance and allocating resources.

The Civil segment specializes in public works construction and the replacement and reconstruction of infrastructure. The contracting services provided by the Civil segment include construction and rehabilitation of highways, bridges, tunnels, mass-transit systems, and water management and wastewater treatment facilities.

The Building segment has significant experience providing services for private and public works customers in a number of specialized building markets, including: high-rise residential, hospitality and gaming, transportation, health care, commercial and government offices, sports and entertainment, education, correctional facilities, biotech, pharmaceutical, industrial and ~~high-tech.~~technology.

The Specialty Contractors segment specializes in electrical, mechanical, plumbing, HVAC, fire protection systems and pneumatically placed concrete for a full range of civil and building construction projects in the industrial, commercial, hospitality and gaming, and mass-transit end markets. This segment provides the Company with unique strengths and capabilities that allow the Company to position itself as a full-service contractor with greater control over scheduled work, project delivery, and cost and risk management.

To the extent that a contract is co-managed and co-executed among segments, the Company allocates the share of revenues and costs of the contract to each segment to reflect the shared responsibilities in the management and execution of the project.
