Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries and joint ventures. Significant intercompany accounts and transactions have been eliminated. All investments over which we exercise significant influence, but do not control (a 20% to 50% ownership interest), are accounted for using the equity method of accounting. For joint ventures that have been accounted for using the consolidation method of accounting, noncontrolling interests represent the allocation of earnings to our joint venture partners who either have a minority-ownership interest in the joint venture or are not at risk for the majority of losses of the joint venture. The results of operations of companies acquired have been included in the results of operations from the date of the respective acquisition. Principles of Preparation The preparation of the consolidated financial statements, in conformity with accounting principles generally accepted in the United States, requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates. Our reportable segments and related disclosures reflect certain reclassifications of prior year amounts from our United States electrical construction and facilities services segment to our United States industrial services and our United States building services segments due to changes in our internal reporting structure aimed at realigning our service offerings. Revenue Recognition Revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. Refer to Note 3 - Revenue from Contracts with Customers of the notes to consolidated financial statements for additional information. Cash and Cash Equivalents For purposes of the consolidated financial statements, we consider all highly liquid instruments with original maturities of three months or less to be cash equivalents. We maintain a centralized cash management system whereby our excess cash balances are invested in high quality short-term money market instruments, which are considered cash equivalents. We have cash balances in certain of our domestic bank accounts that exceed federally insured limits. Accounts Receivable and Allowance for Credit Losses Accounts receivable are recognized in the period we deliver goods and services to our customers or when our right to consideration is unconditional. The Company maintains an allowance for credit losses to reduce outstanding receivables to their net realizable value. A considerable amount of judgment is required when determining expected credit losses. Estimates of such losses are recorded when we believe a customer, or group of customers, may not be able to meet their financial obligations due to deterioration in financial condition or credit rating. Factors relevant to our assessment include our prior collection history with our customers, the related aging of past due balances, projections of credit losses based on historical trends in credit quality indicators or past events, and forecasts of future economic conditions. In addition to monitoring delinquent accounts, management reviews the credit quality of its receivables by, among other things, obtaining credit ratings of significant customers, assessing economic and market conditions, and evaluating material changes to a customer’s business, cash flows, and financial condition. NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) At December 31, 2021 and 2020, our accounts receivable of $2,204.5 million and $1,922.1 million, respectively, were recorded net of allowances for credit losses of $23.5 million and $18.0 million, respectively. The increase in our allowance for credit losses was predominantly attributable to our evaluation of specific outstanding receivables within our United States industrial services segment. Allowances for credit losses are based on the best facts available and are reassessed and adjusted on a regular basis as additional information is received. Should anticipated collections fail to materialize, or if future economic conditions compare unfavorably to our forecasts, we could experience an increase in our credit losses. The provision for credit losses during 2021, 2020, and 2019 amounted to approximately $8.0 million, $3.3 million, and $2.6 million, respectively. The change in the allowance for credit losses for the year ended December 31, 2021 was as follows (in thousands):
Balance at December 31, 2020 | $ | 18,031 |
Provision for credit losses | 8,041 |
Amounts written off against the allowance, net of recoveries | (2,538) |
Balance at December 31, 2021 | $ | 23,534 |
Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined principally using the average cost method. Leases At the inception of a contract, we determine whether the arrangement is or contains a lease. Leases are classified as either operating or finance, based on our evaluation of certain criteria. With the exception of short-term leases (leases with an initial term of 12 months or less), we record right-of-use assets and corresponding lease liabilities on the Consolidated Balance Sheets for all leases with contractual fixed payments. Lease liabilities are measured at the present value of remaining lease payments, while right-of-use assets are initially set equal to the lease liability, as adjusted for any payments made prior to lease commencement, lease incentives, and any initial direct costs incurred by us. For operating leases, rent expense is recognized on a straight-line basis over the term of the lease, and right-of-use assets are subsequently re-measured to reflect the effect of uneven lease payments. For finance leases, right-of-use assets are amortized on a straight-line basis over the lease term. Expenses for finance leases include the amortization of right-of-use assets, which is recorded as depreciation and amortization expense, and interest expense, which reflects interest accrued on the lease liability. Short-term leases are not recorded on the Consolidated Balance Sheets but are expensed on a straight-line basis over the lease term. The majority of the Company’s short-term leases relate to equipment used on construction projects. Such equipment leases are considered short-term in nature unless it is reasonably certain that the equipment will be leased for a period greater than 12 months. Refer to Note 16 - Leases of the notes to consolidated financial statements for additional information. Property, Plant and Equipment Property, plant and equipment is stated at cost. Depreciation, including amortization of assets under finance leases, is recorded principally using the straight-line method over estimated useful lives of 3 to 10 years for machinery and equipment, 3 to 7 years for vehicles, furniture and fixtures and computer hardware/software, and 25 years for buildings. Leasehold improvements are amortized over the shorter of the remaining lease term or the expected useful life of the improvement. The carrying values of property, plant and equipment are reviewed for impairment whenever facts and circumstances indicate that the carrying amount may not be fully recoverable. In performing this review for recoverability, property, plant and equipment is assessed for possible impairment by comparing their carrying values to their undiscounted net pre-tax cash flows expected to result from the use of the asset. Impaired assets are written down to their fair values, generally determined based on their estimated future discounted cash flows. NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Goodwill, Identifiable Intangible Assets, and Other Long-Lived Assets Goodwill and indefinite-lived intangible assets, such as trade names, are evaluated at least annually for impairment (each October 1, absent any earlier identified impairment indicators) and are written down if impaired. Identifiable intangible assets with finite lives are amortized over their useful lives and are reviewed for impairment whenever facts and circumstances indicate that their carrying values may not be fully recoverable. See Note 8 - Goodwill, Identifiable Intangible Assets, and Other Long-Lived Assets of the notes to consolidated financial statements for additional information. Insurance Liabilities We have loss payment deductibles for certain workers’ compensation, automobile liability, general liability, and property claims, have self-insured retentions for certain other casualty claims, and are self-insured for employee-related healthcare claims. In addition, we maintain a wholly-owned captive insurance subsidiary to manage certain of our insurance liabilities. Losses are recorded based upon estimates of our liability for claims incurred and for claims incurred but not reported. The liabilities are derived from known facts, historical trends, and industry averages, utilizing the assistance of an independent third-party actuary to determine the best estimate for the majority of these obligations. As of December 31, 2021 and 2020, the estimated current portion of such undiscounted insurance liabilities, included in “Other accrued expenses and liabilities” in the accompanying Consolidated Balance Sheets, were $61.5 million and $48.2 million, respectively. The estimated non-current portion of such undiscounted insurance liabilities included in “Other long-term obligations” as of December 31, 2021 and 2020 were $242.4 million and $192.8 million, respectively. The current portion of anticipated insurance recoveries of $26.4 million and $14.4 million as of December 31, 2021 and 2020, respectively, were included in “Prepaid expenses and other” and the non-current portion of anticipated insurance recoveries of $99.0 million and $54.3 million as of December 31, 2021 and 2020, respectively, were included in “Other assets” in the accompanying Consolidated Balance Sheets. These balances increased from December 31, 2020 as a result of revised estimates for claims on which we expect substantial coverage by insurance. Foreign Operations The financial statements and transactions of our foreign subsidiaries are maintained in their functional currency and translated into U.S. dollars when preparing our consolidated financial statements. Statements of operations, comprehensive income, and cash flows are translated using weighted average monthly exchange rates, while balance sheets are translated at month-end exchange rates. Translation adjustments are recorded as “Accumulated other comprehensive loss,” a separate component of “Equity.” Income Taxes The Company follows the liability method of accounting for income taxes. Under this method, deferred income tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial statement and income tax bases of assets and liabilities as well as for net operating loss and tax credit carryforwards. Deferred income taxes are valued using enacted tax rates expected to be in effect when income taxes are paid or recovered, with the effect of a change in tax laws or rates recognized in the statement of operations in the periods in which such change is enacted. The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the period in which those temporary differences become deductible. Deferred income taxes are recorded net of a valuation allowance when it is more likely than not that all or a portion of a deferred tax asset will not be realized. In making such determination, we consider all available evidence, including projections of future taxable income, tax-planning strategies, and recent results of operations. Tax benefits associated with uncertain tax positions are recognized only if it is more likely than not that the tax position would be sustained on its technical merits. For positions not meeting the “more likely than not” test, no tax benefit is recognized. To the extent interest and penalties may be assessed related to unrecognized tax benefits, we record accruals for such amounts as a component of the income tax provision. We had no unrecognized income tax benefits as of December 31, 2021 and 2020. NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Valuation of Share-Based Compensation Plans Our share-based compensation plans and programs are administered by our Board of Directors or its Compensation and Personnel Committee. See Note 13 - Share-Based Compensation Plans of the notes to consolidated financial statements for additional information regarding these share-based compensation plans and programs. We recognize all share-based payments issued to acquire goods or services in the statement of operations based on the fair value of such payments. Compensation expense related to share-based awards is generally recognized on a straight-line basis over the requisite service period, which is generally the vesting period. The benefits of tax deductions in excess of recognized compensation expense are recognized in the Consolidated Statements of Operations when the underlying awards vest or are settled. New Accounting Pronouncements On January 1, 2021, we adopted the accounting pronouncement issued by the Financial Accounting Standards Board (“FASB”) that simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in Accounting Standards Codification (“ASC”) 740 related to intraperiod tax allocations and the methodology for calculating income taxes in an interim period. The guidance also simplifies aspects of the accounting for franchise taxes as well as enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The adoption of this accounting pronouncement did not have a material impact on our financial position and/or results of operations. The Company is currently evaluating the impact of an accounting standards update issued by the FASB, which provides temporary optional expedients and exceptions to existing U.S. GAAP. This guidance is aimed at easing the financial reporting burdens related to reference rate reform, including the expected market transition from LIBOR, or other interbank offered rates, to alternative reference rates. Such accounting pronouncement allows entities to account for and present certain contract modifications, which occur before December 31, 2022 and result from the transition to an alternative reference rate, as an event that does not require remeasurement at the modification date or reassessment of a previous accounting determination. While we are still evaluating the impact of this pronouncement, we do not anticipate that it will have a material impact on our financial position and/or results of operations, as we are not exposed to any contracts that reference LIBOR, other than our credit agreement dated as of March 2, 2020, which contains provisions that allow for the amendment of such agreement to use alternative reference rates in the event of the discontinuation of LIBOR. In October 2021, an accounting pronouncement was issued by the FASB, which changes how an entity accounts for revenue contracts it acquires in a business combination. The pronouncement requires entities to apply the revenue recognition guidance within ASC 606 to recognize and measure contract assets and liabilities from contracts with customers in a business combination, creating an exception to the fair value recognition and measurement principle typically utilized when valuing acquired assets. The guidance is aimed at improving comparability by addressing when an acquirer should recognize a contract asset or contract liability, as well as how such assets and liabilities should be measured, and will generally result in companies recognizing contract assets and contract liabilities at amounts consistent with those recorded by the target entity prior to acquisition. This guidance is effective for public business entities for fiscal years beginning after December 15, 2022, with early adoption permitted. We are currently evaluating the potential impact of this accounting pronouncement; however, we do not believe that its adoption will have a material impact on our financial position and/or results of operations.
