Summary of Significant Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | 1. Summary of Significant Accounting Policies ﻿ (a) Basis of Presentation ﻿ The accompanying consolidated financial statements have been prepared in compliance with accounting principles generally accepted in the United States of America (“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 frequently forms joint ventures or partnerships with unrelated third parties for the execution of single contracts or projects. The Company assesses its joint ventures or partnerships at inception to determine if they meet the qualifications of a variable interest entity ("VIE") in accordance with ASC 810, Consolidation. If a joint venture or partnership is a VIE and the Company is the primary beneficiary, the joint venture or partnership is fully consolidated. 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. All intercompany transactions and balances have been eliminated in consolidation. ﻿ (c) Use of Estimates ﻿ 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) Construction Contracts ﻿ The Company and its affiliated entities recognize construction contract revenue using the percentage-of-completion method, based primarily on contract cost incurred to date compared to total estimated contract cost. Cost of revenue includes an allocation of depreciation and amortization. Pre-contract costs are expensed as incurred. Changes to total estimated contract cost or losses, if any, are recognized in the period in which they are determined. ﻿ The Company generally provides limited warranties for work performed under its construction contracts with 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. ﻿ The Company classifies construction-related receivables and payables that may be settled in periods exceeding one year from the balance sheet date as current, consistent with the length of time of its project operating cycle. For example: ﻿
| · |  | 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.
﻿
| · |  | 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 and are classified as a current liability.
﻿ Costs and estimated earnings in excess of billings result when either: 1) the appropriate contract revenue amount has been recognized in accordance with the percentage-of-completion accounting method, but a portion of the revenue recorded cannot be billed currently due to the billing terms defined in the contract, or 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. For both claims and unapproved change orders, the Company recognizes revenue, but not profit, when it is determined that recovery of incurred cost is probable and the amounts can be reliably estimated. For claims, these requirements are satisfied under ASC 605-35-25 when the contract or other evidence provides a legal basis for the claim, additional costs were caused by circumstances that were unforeseen at the contract date and not the result of deficiencies in the Company’s performance, claim-related costs are identifiable and considered reasonable in view of the work performed, and evidence supporting the claim or change order is objective and verifiable. ﻿ Reported costs and estimated earnings in excess of billings consists of the following: ﻿ ﻿
﻿ |  |  |  |  |
﻿ |  |  |  |  |
﻿ | As of December 31,
﻿(in thousands) | 2016 |  | 2015
﻿Claims | $ | 477,425 |  | $ | 407,164
﻿Unapproved change orders |  | 207,475 |  |  | 270,019
﻿Other unbilled costs and profits |  | 146,926 |  |  | 227,992
﻿Total costs and estimated earnings in excess of billings | $ | 831,826 |  | $ | 905,175
﻿ The prerequisite for billing claims and unapproved change orders is the final resolution and agreement between the parties. The prerequisite for billing other unbilled costs and profits is provided in the defined billing terms of each of the applicable contracts. The amount of costs and estimated earnings in excess of billings as of December 31, 2016 estimated by management to be collected beyond one year is approximately $414.7 million. ﻿ (e) Changes in Estimates ﻿ 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 close-out 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 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. ﻿ (f) Depreciation of Property and Equipment and Amortization of Long-Lived Intangible Assets ﻿ Property and equipment and long-lived intangible assets are depreciated or amortized on a straight-line basis over their estimated useful lives ranging from three to forty years. ﻿ (g) 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. ﻿ (h) Recoverability of Goodwill ﻿ The Company tests goodwill for impairment annually for each reporting unit in the fourth quarter of the fiscal year, 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. We perform our 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. The market approach is based on assumptions about how market data relates to the Company. The weighting of these two approaches is based on their individual correlation to the economics of each reporting unit. The quantitative assessment performed in 2016 resulted in an estimated fair value for each of our reporting units that exceeded their respective net book values; therefore, no impairment charge was necessary for 2016. ﻿ (i) 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. We perform our annual quantitative impairment assessment during the fourth quarter of each year using an income approach (relief from royalty method). The quantitative assessment performed in 2016 resulted in an estimated fair value for the non-amortizable trade names that exceeded their respective net book values; therefore, no impairment charge was necessary for 2016. ﻿ (j) 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. ﻿ (k) Earnings Per Share ﻿ Basic EPS is calculated by dividing net income by the weighted-average number of common shares outstanding during the period. Potentially dilutive securities include restricted stock units and stock options. Diluted EPS reflects the assumed exercise or conversion of all dilutive securities using the treasury stock method. The calculations of the basic and diluted EPS for the years ended December 31, 2016, 2015 and 2014 are presented below: ﻿
﻿ |  |  |  |  |  |  |  |
﻿ |  |  |  |  |  |  |  |
﻿ | Year Ended December 31,
﻿(in thousands, except per share data) | 2016 |  | 2015 |  | 2014
﻿Net income | $ | 95,822 |  | $ | 45,292 |  | $ | 107,936
﻿ |  |  |  |  |  |  |  |
﻿Weighted-average common shares outstanding — basic |  | 49,150 |  |  | 48,981 |  |  | 48,562
﻿Effect of diluted stock options and unvested restricted stock |  | 714 |  |  | 685 |  |  | 552
﻿Weighted-average common shares outstanding — diluted |  | 49,864 |  |  | 49,666 |  |  | 49,114
﻿ |  |  |  |  |  |  |  |
﻿Net income per share: |  |  |  |  |  |  |  |
﻿Basic | $ | 1.95 |  | $ | 0.92 |  | $ | 2.22
﻿Diluted | $ | 1.92 |  | $ | 0.91 |  | $ | 2.20
﻿Anti-dilutive securities not included above |  | 1,132 |  |  | 1,372 |  |  | 9
﻿ With regard to diluted EPS and the impact of the Convertible Notes (as discussed in Note 5) on the diluted EPS calculation, because the Company has the intent and ability to settle the principal amount of the Convertible Notes in cash, per ASC 260, Earnings Per Share, the settlement of the principal amount has no impact on diluted EPS. ASC 260 also requires any potential conversion premium associated with the Convertible Notes’ conversion option to be considered in the calculation of diluted EPS when the Company's average stock price, as defined in the indenture governing the Convertible Notes, is higher than 130% of the Convertible Notes’ conversion rate of 33.0579 (or $39.32); however, this was not the case during the year ended December 31, 2016. ﻿ (l) Cash and Cash Equivalents and Restricted Cash ﻿ Cash equivalents include short-term, highly liquid investments with original maturities of three months or less when acquired. Cash and cash equivalents, as reported in the accompanying Consolidated Balance Sheets, consist of amounts held by the Company that are available for general purposes and the Company’s proportionate share of amounts held by construction joint ventures that are available only for joint-venture-related uses, including future distributions to joint-venture partners. Restricted cash is primarily held to secure insurance-related contingent obligations, such as insurance claim deductibles, in lieu of letters of credit. ﻿ Cash and cash equivalents and restricted cash consisted of the following: ﻿ ﻿ ﻿
﻿ |  |  |  |  |
﻿ |  |  |  |  |
﻿ | As of December 31,
﻿(in thousands) | 2016 |  | 2015
﻿Cash and cash equivalents | $ | 49,539 |  | $ | 18,409
﻿Company's share of joint-venture cash and cash equivalents |  | 96,564 |  |  | 57,043
﻿Total cash and cash equivalents | $ | 146,103 |  | $ | 75,452
﻿ |  |  |  |  |
﻿Restricted cash | $ | 50,504 |  | $ | 45,853
﻿ (m) Share-Based Compensation ﻿ The Company’s long-term incentive plan allows 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 service period. Unrestricted stock units are issued to the directors as part of their annual service fee, vest immediately and are expensed over a 12-month service period. ﻿ (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 plans assets/liabilities, cumulative foreign currency translation, change in fair value of investments and change in fair value of interest rate swap as components of accumulated other comprehensive loss (“AOCI”). ﻿ The tax effects of the components of other comprehensive income (loss) are as follows: ﻿
﻿ |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
﻿ |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

﻿ (p) New Accounting Pronouncements ﻿ In May 2014, the FASB issued new accounting guidance which amended the existing accounting standards for revenue recognition. The new accounting guidance establishes principles for recognizing revenue upon the transfer of promised goods or services to customers, in an amount that reflects the expected consideration to be received in exchange for those goods or services. The guidance will be effective for the Company as of January 1, 2018. The amendments may be applied retrospectively to each prior period presented or with the cumulative effect recognized as of the date of initial application (modified retrospective method). The Company is currently reviewing contracts within types of projects in order to determine the impact, if any, the adoption of this ASU will have on its consolidated financial statements. A number of industry-specific implementation issues are still unresolved and the final resolution of certain of these issues could impact the Company’s current accounting policies and/or revenue recognition patterns. The Company currently expects to adopt this new standard using the modified retrospective method. ﻿ In January 2017, The FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment. This ASU simplifies the calculation of goodwill impairment by eliminating Step 2 of the impairment test prescribed by ASC 350. 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 the Company 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 does not expect the adoption of this ASU to have a material impact on its consolidated financial statements. ﻿ In the first quarter of 2016, the Company adopted ASU 2015-03, Interest – Imputation of Interest (Subtopic 835-30). This ASU requires companies to present, in the balance sheet, debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability, consistent with the presentation of debt discounts. In addition, the amortization of debt discounts is required to be presented as a component of interest expense. The Company applied the guidance retrospectively; accordingly, the Company reclassified unamortized debt issuance costs of $5.8 million from Other Assets to Long-Term Debt, less current maturities in its December 31, 2015 Consolidated Balance Sheet and reclassified amortization of deferred debt issuance costs of $1.1 million and $1.4 million, respectively, from Other income (expense), net to Interest Expense in its Consolidated Statements of Operations for the years ended December 31, 2015 and 2014. ﻿ In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic-842), which amends the existing guidance in ASC 840 Leases. This amendment requires the recognition of lease assets and lease liabilities by lessees for those leases currently classified as operating leases. Other significant provisions of the amendment include (i) defining the “lease term” to include the non-cancellable period together with periods for which there is a significant economic incentive for the lessee to extend or not terminate the lease; (ii) defining the initial lease liability to be recorded on the balance sheet to contemplate only those variable lease payments that depend on an index or that are in substance “fixed”; and (iii) a dual approach for determining whether lease expense is recognized on a straight-line or accelerated basis, depending on whether the lessee is expected to consume more than an insignificant portion of the leased asset’s economic benefits. This guidance will be effective for the Company as of January 1, 2019 and will be applied using the modified retrospective transition method for existing leases. The Company is currently evaluating the effect that the adoption of this ASU will have on its consolidated financial statements. ﻿ In the fourth quarter of 2016, the Company elected to early adopt ASU 2015-17, Balance Sheet Classification of Deferred Taxes (Subtopic 740-10), as allowed for by the guidance. This ASU requires entities to present all deferred tax assets and all deferred tax liabilities as noncurrent in a classified balance sheet. The Company applied the guidance re t rospectively as discussed in Note 6.
