STERLING CONSTRUCTION COMPANY, INC. & SUBSIDIARIES
NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
June 30, 2020
($ and share values in thousands, except per share data)
(Unaudited)

1. | NATURE OF OPERATIONS

Business Summary
Sterling Construction Company, Inc., (“Sterling,” “the Company,” “we,” “our” or “us”), a Delaware corporation, is a construction company that has been involved in the construction industry since its founding in 1955. The Company operates through a variety of subsidiaries within three operating groups specializing in heavy civil, specialty services, and residential projects in the United States (the “U.S.”), primarily across the southern U.S., the Rocky Mountain States, California and Hawaii, as well as other areas with strategic construction opportunities. Heavy civil includes infrastructure and rehabilitation projects for highways, roads, bridges, airfields, ports, light rail, water, wastewater and storm drainage systems. Specialty services projects include construction site excavation and drainage, drilling and blasting for excavation, foundations for multi-family homes, parking structures and other commercial concrete projects. Residential projects include concrete foundations for single-family homes.

2. | BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation
Presentation Basis—The accompanying Condensed Financial Statements are presented in accordance with accounting policies generally accepted in the United States (“GAAP”) and reflect all wholly owned subsidiaries and those entities the Company is required to consolidate. See the “Consolidated 50% Owned Subsidiaries” and “Construction Joint Ventures” section of this Note for further discussion of the Company’s consolidation policy for those entities that are not wholly owned. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation have been included. All significant intercompany accounts and transactions have been eliminated in consolidation. Values presented within tables (excluding per share data) are in thousands. Reclassifications have been made to historical financial data in the Condensed Consolidated Financial Statements to conform to the current year presentation.
Estimates and Judgments—The preparation of the accompanying Condensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Certain accounting estimates of the Company require a higher degree of judgment than others in their application. These include the recognition of revenue and earnings from construction contracts over time, the valuation of long-lived assets, goodwill, income taxes, and purchase accounting estimates, including goodwill and other intangible assets. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.
Significant Accounting Policies
Consistent with Regulation S-X Rule 10-1(a), the Company has omitted significant accounting policies in this quarterly report that would duplicate the disclosures contained in the Company’s annual report on Form 10-K for the year ended December 31, 2019 under “Part II, Item 8. - Notes to Consolidated Financial Statements”.
Receivables, including Retainage—Receivables are generally based on amounts billed to the customer in accordance with contractual provisions. Many of the contracts under which the Company performs work also contain retainage provisions. Retainage refers to that portion of our billings held for payment by the customer pending satisfactory completion of the project. Unless reserved, the Company assumes that all amounts retained by customers under such provisions are fully collectible. Retainage on active contracts is classified as a current asset regardless of the term of the contract and is generally collected within one year of the completion of a contract. At June 30, 2020 and December 31, 2019, receivables included $72,800 and $79,400 of retainage, respectively.
Receivables are written off based on individual credit evaluation and specific circumstances of the customer, when such treatment is warranted. The Company performs a review of outstanding receivables, historical collection information and existing economic conditions to determine if there are potential uncollectible receivables. At both June 30, 2020 and December 31, 2019, our allowance for doubtful accounts against contracts receivable was zero.
9

Cash and Restricted cash—Our cash is comprised of highly liquid investments with maturities of three months or less. Restricted cash of approximately $4,900 and $4,800 is included in “Other current assets” on the Condensed Consolidated Balance Sheets at June 30, 2020 and December 31, 2019, respectively. This primarily represents cash deposited by the Company into separate accounts and designated as collateral for standby letters of credit in the same amount in accordance with contractual agreements.
Recently Adopted Accounting Pronouncements
In June 2016, the FASB issued ASU 2016-13 to add the guidance in ASC 326 on the impairment of financial instruments. The ASU introduces an impairment model (known as the current expected credit loss (CECL) model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which the FASB believes will result in more timely recognition of such losses. The ASU is also intended to reduce the complexity of U.S. GAAP by decreasing the number of credit impairment models that entities use to account for debt instruments. The amendments in the ASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company adopted this guidance effective January 1, 2020 as required and noted no material impact to the Company’s Condensed Consolidated Financial Statements.

3. | PLATEAU ACQUISITION

General—As more fully described in Sterling’s 2019 Annual Report, on October 2, 2019, Sterling consummated the acquisition (the “Plateau Acquisition”) of all of the issued and outstanding shares of capital stock of LK Gregory Construction, Inc. and Plateau Excavation, Inc., and all of the issued and outstanding equity interests in DeWitt Excavation, LLC. The Plateau Acquisition is accounted for using the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations.
Purchase Consideration—Sterling completed the Plateau Acquisition for a purchase price of $427,533, net of cash acquired, detailed as follows:

Cash consideration transferred, net of $2,425 of cash acquired | $ | 375,000 |
Target working capital adjustment | 21,323 |
Equity consideration transferred (1,245 shares at $13.01 per share(1)) | 16,195 |
Note payable to seller (See Note 9 - Debt) | 10,000 |
Tax basis election | 5,015 |
Total consideration | $ | 427,533 |

(1) Sterling’s closing stock price on October 1, 2019
Preliminary Purchase Price Allocation—The aggregate purchase price noted above was allocated to the assets and liabilities acquired based upon their estimated fair values at the acquisition closing date, which were based, in part, upon an external preliminary appraisal and valuation of certain assets, including specifically identified intangible assets. The excess of the purchase price over the preliminary estimated fair value of the net tangible and identifiable intangible assets acquired totaling $106,784, was recorded as goodwill.
The following table summarizes our purchase price allocation at the acquisition closing date, net of cash acquired:

Net tangible assets: |
Accounts receivable, including retainage | $ | 81,921 |
Costs and estimated earnings in excess of billings | 974 |
Other current assets | 249 |
Property and equipment, net | 65,492 |
Other non-current assets, net | 10 |
Accounts payable | (22,039) |
Billings in excess of costs and estimated earnings | (16,540) |
Other current and non-current liabilities | (7,918) |
Total net tangible assets | 102,149 |
Identifiable intangible assets | 218,600 |
Goodwill | 106,784 |
Total consideration transferred | $ | 427,533 |

10

The purchase price allocation above is subject to further change when additional information is obtained. We have not finalized our assessment of the fair values primarily for intangible assets and property and equipment. We intend to finalize the purchase price allocation as soon as practicable within the measurement period, but in no event later than one year following the closing date of the Plateau Acquisition. Our final purchase price allocation may result in additional adjustments to various other assets and liabilities, including the residual amount allocated to goodwill during the measurement period.
Identifiable Intangible Assets—Intangible assets identified as part of the Plateau Acquisition are reflected in the table below and are recorded at their estimated fair value, as determined by the Company’s management, based on available information which includes a preliminary valuation from external experts. The estimated useful lives for intangible assets were determined based upon the remaining useful economic lives of the intangible assets that are expected to contribute directly or indirectly to future cash flows.

| Weighted Average Life (Years) |  | October 2, 2019 Fair Value
Customer relationships | 25 |  | $ | 191,800 |
Trade name | 25 |  | 24,800 |
Non-compete agreements | 5 |  | 2,000 |
Total |  |  | $ | 218,600 |

Supplemental Pro Forma Information (Unaudited)—The following unaudited pro forma combined financial information (“the pro forma financial information”) gives effect to the Plateau Acquisition, accounted for as a business combination using the purchase method of accounting. The pro forma financial information reflects the Plateau Acquisition and related events as if they occurred at the beginning of the period, and gives effect to pro forma events that are: directly attributable to the acquisition, factually supportable and expected to have a continuing impact on the combined results of Sterling and Plateau following the Plateau Acquisition. The pro forma financial information includes adjustments to: (1) exclude transaction costs that were included in historical results and are expected to be non-recurring, (2) include additional intangibles amortization and net interest expense associated with the Plateau Acquisition and (3) include the pro forma results of Plateau for the three and six months ended ended June 30, 2019. This pro forma financial information has been presented for illustrative purposes only and is not necessarily indicative of the operating results that would have been achieved had the pro forma events taken place on the dates indicated. Further, the pro forma financial information does not purport to project the future operating results of the combined company following the Plateau Acquisition.

| Three Months Ended June 30, 2019 |  | Six Months Ended June 30, 2019
Pro forma revenue | $ | 347,862 |  |  | $ | 630,471 |
Pro forma net income attributable to Sterling | $ | 20,992 |  |  | $ | 28,323 |

4. | REVENUE FROM CUSTOMERS

Backlog
The Company had the following backlog, by segment:

|  |  |  |  | June 30, 2020 |  | December 31, 2019
Heavy Civil Backlog |  |  |  |  | $ | 874,822 |  |  | $ | 834,049 |
Specialty Services Backlog |  |  |  |  | 258,992 |  |  | 233,976 |
Total Heavy Civil and Specialty Services Backlog |  |  |  |  | $ | 1,133,814 |  |  | $ | 1,068,025 |

The Company expects to recognize approximately 63% of its backlog as revenue during the next twelve months, and the balance thereafter.

Land Development | $ | 105,639 |  |  | $ | — |  |  | $ | 181,884 |  |  | $ | — |  |  |  |  |  |  |
Commercial | 30,064 |  |  | 27,894 |  |  | 58,542 |  |  | 58,573 |  |  |  |  |  |  |
Specialty Services Revenue | $ | 135,703 |  |  | $ | 27,894 |  |  | $ | 240,426 |  |  | $ | 58,573 |  |  |  |  |  |  |
Residential Revenue | $ | 43,887 |  |  | $ | 35,956 |  |  | $ | 80,237 |  |  | $ | 78,721 |  |  |  |  |  |  |
Revenues | $ | 400,038 |  |  | $ | 264,086 |  |  | $ | 696,726 |  |  | $ | 488,035 |  |  |  |  |  |  |
Revenue by contract type |  |  |  |  |  |  |  |  |  |  |  |  |
Fixed-Unit Price | $ | 203,692 |  |  | $ | 185,297 |  |  | $ | 345,431 |  |  | $ | 326,516 |  |  |  |  |  |  |
Lump Sum | 147,460 |  |  | 43,666 |  |  | 261,712 |  |  | 82,798 |  |  |  |  |  |  |
Residential and Other | 48,886 |  |  | 35,123 |  |  | 89,583 |  |  | 78,721 |  |  |  |  |  |  |
Revenues | $ | 400,038 |  |  | $ | 264,086 |  |  | $ | 696,726 |  |  | $ | 488,035 |  |  |  |  |  |  |

Each of these contract types presents advantages and disadvantages. Typically, the Company assumes more risk with lump-sum contracts. However, these types of contracts offer additional profits if the work is completed for less than originally estimated. Under fixed-unit price contracts, the Company’s profit may vary if actual labor-hour costs vary significantly from the negotiated rates. Also, because some contracts can provide little or no fee for managing material costs, the components of contract cost can impact profitability.
Variable Consideration
The Company has projects that it is in the process of negotiating, or awaiting final approval of, unapproved change orders and claims with its customers. The Company is proceeding with its contractual rights to recoup additional costs incurred from its customers based on completing work associated with change orders, including change orders with pending change order pricing, or claims related to significant changes in scope which resulted in substantial delays and additional costs in completing the work. Unapproved change order and claim information has been provided to the Company’s customers and negotiations with the customers are ongoing. If additional progress with an acceptable resolution is not reached, legal action will be taken.
Based upon the Company’s review of the provisions of its contracts, specific costs incurred and other related evidence supporting the unapproved change orders and claims, together in some cases as necessary with the views of the Company’s outside claim consultants, the Company concluded it was appropriate to include in project price amounts of $8,200 and $3,000, at June 30, 2020 and December 31, 2019, respectively, relating to unapproved change orders and claims. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined.
Contract Estimates
Accounting for long-term contracts and programs involves the use of various techniques to estimate total contract revenue and costs. For long-term contracts, the Company estimates the profit on a contract as the difference between the total estimated revenue and expected costs to complete a contract and recognizes such profit over the life of the contract.
Contract estimates are based on various assumptions to project the outcome of future events that often span several years. These assumptions include labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials and the performance of subcontractors. Changes in job performance, job conditions and estimated profitability, including those changes arising from contract penalty provisions and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined.
12

Changes in estimated revenues and gross margin resulted in net increases of $2,197 and $2,292 for the three and six months ended June 30, 2020, and net increases of $3,500 and $3,300 for the three and six months ended June 30, 2019, included in “Operating income” on the Condensed Consolidated Statements of Operations.

5. | CONSOLIDATED 50% OWNED SUBSIDIARIES

The Company has 50% ownership interests in two subsidiaries (“Myers” and “RHB”) that it fully consolidates as a result of its exercise of control over the entities. The earnings attributable to the 50% portions the Company does not own were approximately $4,600 and $6,300 for the three and six months ended June 30, 2020, respectively, and $1,400 and $2,700 for the three and six months ended June 30, 2019, respectively, and are eliminated within “Other operating expense, net” in the Condensed Consolidated Statements of Operations. Any undistributed earnings for partners are included in “Members’ interest subject to mandatory redemption and undistributed earnings” within the Condensed Consolidated Balance Sheets and are mandatorily payable at the time of the noncontrolling owners’ death or permanent disability.
These two subsidiaries have individual mandatory redemption provisions which, under circumstances outlined in the partner agreements, are certain to occur and obligate the Company to purchase each partner’s remaining 50% interests for $20,000 ($40,000 in the aggregate). The Company has purchased two separate $20,000 death and permanent total disability insurance policies to mitigate the Company’s cash draw if such events were to occur. These purchase obligations are recorded in “Members’ interest subject to mandatory redemption and undistributed earnings” on the Condensed Consolidated Balance Sheets.
The liability consists of the following:

| June 30, 2020 |  | December 31, 2019
Members’ interest subject to mandatory redemption | $ | 40,000 |  |  | $ | 40,000 |
Net accumulated earnings | 13,751 |  |  | 9,003 |
Total liability | $ | 53,751 |  |  | $ | 49,003 |

The Company must determine whether any of its entities, including these two 50% owned subsidiaries, in which it participates, is a VIE. The Company determined Myers is a VIE, as the Company is the primary beneficiary, as pursuant to the terms of the Myers Operating Agreement the Company is exposed to the majority of potential losses of the partnership.
Summary financial information for Myers is as follows:

| Three Months Ended June 30, |  |  |  | Six Months Ended June 30, |  |
| 2020 |  | 2019 |  | 2020 |  | 2019
Revenues | $ | 54,364 |  |  | $ | 59,664 |  |  | $ | 98,726 |  |  | $ | 102,078 |
Operating income | $ | 1,049 |  |  | $ | 2,004 |  |  | $ | 1,204 |  |  | $ | 2,281 |
Net income | $ | 1,051 |  |  | $ | 2,009 |  |  | $ | 1,209 |  |  | $ | 2,291 |

6. | CONSTRUCTION JOINT VENTURES

The Company participates in joint ventures with other major construction companies and other partners, typically for large, technically complex projects, including design-build projects, when it is desirable to share risk and resources in order to seek a competitive advantage. Joint venture partners typically provide independently prepared estimates, furnish employees and equipment, enhance bonding capacity and often also bring local knowledge and expertise. These projects generally have joint and several liability. The Company selects joint venture partners based on its analysis of their construction and financial capabilities, expertise in the type of work to be performed and past working relationships with the Company, among other criteria.
Joint ventures with a controlling interest—Where the Company has a controlling joint interest in a venture, the equity held by the remaining owners and their portions of net income (loss) are reflected in the Condensed Consolidated Balance Sheets line item “Noncontrolling interests” in “Stockholders’ equity” and the Condensed Consolidated Statements of Operations line item “Net income attributable to noncontrolling interests,” respectively. The Condensed Consolidated Statements of Changes in Stockholders’ Equity summarize the changes in the noncontrolling owners’ interests in subsidiaries and consolidated joint ventures.
13

Joint ventures with a noncontrolling interest—Where the Company has a noncontrolling joint interest in a venture, the Company accounts for its share of the operations of such construction joint ventures on a pro-rata basis using proportionate consolidation on its Condensed Consolidated Statements of Operations and as a single line item in “Receivables from and equity in construction joint ventures” in the Condensed Consolidated Balance Sheets. This method is an acceptable modification of the equity method of accounting which is a common practice in the construction industry. Condensed combined financial amounts of joint ventures in which the Company has a noncontrolling interest and the Company’s share of such amounts which are included in the Company’s Condensed Consolidated Financial Statements are shown below:

| June 30, 2020 |  | December 31, 2019
Current assets | $ | 136,284 |  |  | $ | 92,710 |
Current liabilities | $ | (142,553) |  |  | $ | (86,705) |
Sterling’s receivables from and equity in construction joint ventures | $ | 12,396 |  |  | $ | 9,196 |

| Three Months Ended June 30, |  |  |  | Six Months Ended June 30, |  |
| 2020 |  | 2019 |  | 2020 |  | 2019

The caption “Receivables from and equity in construction joint ventures,” includes undistributed earnings and receivables owed to the Company. Undistributed earnings are typically released to the joint venture partners after the customer accepts the project as completed and the warranty period, if any, has passed.
The Company must determine whether each joint venture in which it participates is a VIE. This determination focuses on identifying which joint venture partner, if any, has the power to direct the activities of a joint venture and the obligation to absorb losses of the joint venture or the right to receive benefits from the joint venture in excess of their ownership interests and could have the effect of requiring us to consolidate joint ventures in which we have a noncontrolling variable interest.
The Company determined that the joint venture between Ralph L Wadsworth Construction, LLC, a subsidiary of the Company (“RLW”) (51% owner) and SEMA Construction Inc (“SEMA”) (49% owner) is a VIE as the Company is the primary beneficiary, as pursuant to the terms of the SEMA Operating Agreement the Company is exposed to 51% of potential losses of the partnership.

Credit Facility—On October 2, 2019, the Company, as borrower, and certain of its subsidiaries, as guarantors, entered into a Credit Agreement (the “Credit Agreement”) with BMO Harris Bank N.A., as administrative agent (the “Agent”), Bank of America, N.A., as syndication agent, and BMO Capital Markets Corp. and BofA Securities, Inc., as joint lead arrangers and joint book runners. The Credit Agreement provides the Company with senior secured debt financing in an amount up to $475,000 in the aggregate, consisting of (i) a senior secured first lien revolving credit facility (the “Revolving Credit Facility”) in an aggregate principal amount of $75,000 (with a $75,000 limit for the issuance of letters of credit and a $15,000 sublimit for swing line loans) and (ii) a senior secured first lien term loan facility (the “Term Loan Facility”) in the amount of $400,000 (collectively, the “Credit Facility”). The obligations under the Credit Facility are secured by substantially all assets of the Company and the subsidiary guarantors, subject to certain permitted liens and interests of other parties. The Credit Facility will mature on October 2, 2024.
The Revolving Credit Facility bears interest at either the Base Rate plus a margin (4.25% and 3.50% per annum, respectively at June 30, 2020), or one-, two-, three-, six- or, if available, twelve-month LIBOR plus an applicable margin (0.19% and 4.50% per annum, respectively at June 30, 2020, using a one-month LIBOR rate), at the Company’s election. In addition to interest on debt borrowings, we are assessed quarterly commitment fees on the unutilized portion of the facility as well as letter of credit fees on outstanding instruments. Interest under the Revolving Credit Facility is payable (i) with respect to LIBOR borrowings, on the last day of each applicable interest period (one, two, three, six or twelve months), unless the applicable interest period is longer than three months, then on each day occurring every three months after the commencement of such interest period, and on the maturity date, and (ii) with respect to Base Rate borrowings, on the last day of every calendar quarter and on the maturity date. At June 30, 2020, we had $20,000 of outstanding borrowings under the facility, providing $55,000 of available capacity. During the six months ended June 30, 2020, our weighted average interest rate on borrowings under the Revolving Credit Facility was approximately 7.15%. The Revolving Credit Facility may be repaid in whole or in part at any time, with final payment of all principal and interest then outstanding due on October 2, 2024.
Interest under the Term Loan Facility is payable at the same frequencies and bears interest at the same rate options as the Revolving Credit Facility. We utilize an interest rate swap to hedge against $350,000 of the outstanding Term Loan Facility, which resulted in a weighted average interest rate of approximately 5.80% per annum during the six months ended June 30, 2020. At June 30, 2020, we had $390,000 of outstanding borrowings under the facility. Principal payments on the Term Loan Facility total $30,000, $50,000, $50,000, $50,000 and $220,000 for each of the years ending 2020, 2021, 2022, 2023, and 2024, respectively. A final payment of all principal and interest then outstanding on the Term Loan Facility is due on October 2, 2024.
The Credit Agreement contains various affirmative and negative covenants that may, subject to certain exceptions, restrict the ability of us and our subsidiaries to, among other things, grant liens, incur additional indebtedness, make loans, advances or other investments, make non-ordinary course asset sales, declare or pay dividends or make other distributions with respect to equity interests, purchase, redeem or otherwise acquire or retire capital stock or other equity interests, or merge or consolidate with any other person, among various other things. In addition, the Company is required to maintain the following financial covenants:
•a Total Leverage Ratio (as defined in the Credit Agreement) at the last day of each fiscal quarter not to be greater than 4.00 to 1.00 ending on December 31, 2019 through and including June 30, 2020, 3.75 to 1.00 ending on September 30, 2020, 3.50 to 1.00 ending on December 31, 2020 through and including March 31, 2021, 3.25 to 1.00 ending on June 30, 2021 through and including September 30, 2021, and 3.00 to 1.00 ending on December 31, 2021 and thereafter; and
•a Fixed Charge Coverage Ratio (as defined in the Credit Agreement) of not less than 1.20 to 1.00 as of the last day of each fiscal quarter of the Company, commencing with the fiscal quarter ending December 31, 2019.
Debt issuance costs—The costs associated with the Term Loan Facility and Revolving Credit Facility are reflected on the Balance Sheets as a direct reduction from the related debt liability and amortized over the terms of the respective facilities. Amortization of debt issuance costs was $740 and $1,491 for the three and six months ended June 30, 2020, respectively, and $518 and $1,037 for the three and six months ended June 30, 2019, respectively, and was recorded as interest expense.
Note Payable to Seller, Plateau Acquisition—As part of the Plateau Acquisition, the Company issued a $10,000 subordinated promissory note to one of the Plateau sellers that bears interest at 8% with interest payments due quarterly beginning January 1, 2020. The subordinated promissory note has no scheduled payments, however, it may be repaid in whole or in part at any time, subject to certain payment restrictions under a subordination agreement with the Agent under our Credit Agreement, without premium or penalty, with final payment of all principal and interest then outstanding due on April 2, 2025.
Notes and deferred Payments to Sellers, Tealstone Acquisition—At June 30, 2020 the Company had no balance remaining on the combined promissory notes and deferred cash payments issued as part of the Tealstone Acquisition. During the three and six months ended June 30, 2020, the Company paid $5,000 of deferred cash payments and $7,500 on promissory notes that were due on April 3, 2020.

Finance Leases and Other Debt—The Company had finance leases of $659 and $764 at June 30, 2020 and December 31, 2019, respectively. The finance leases have payment terms ranging from 3 to 5 years and the associated interest rates range from 2.99% to 6.92%. Additionally, during the three and six months ended June 30, 2020, the Company’s two 50% owned subsidiaries received three short-term Paycheck Protection Program loans totaling approximately $9,800. The loans may be fully or partially forgiven if the funds are used for payroll related costs, interest on mortgages, rent, and utilities, and as long as our employee headcount and salary levels remain consistent with our baseline period over an eight to twenty-four week period following the date the loans were received, otherwise the loans will be repaid following a six month deferral at a 1% interest rate. Any forgiveness of the loans is subject to approval by the Small Business Administration. The loans have been classified as short-term debt on the Condensed Consolidated Balance Sheets at June 30, 2020.
Compliance and other—As of June 30, 2020, we were in compliance with all of our restrictive and financial covenants. The Company’s debt is recorded at its carrying amount in the Condensed Consolidated Balance Sheets. As of June 30, 2020 and December 31, 2019, the carrying values of our debt outstanding approximated the fair values.

11. | FINANCIAL INSTRUMENTS

Derivatives
Interest Rate Derivative—We continue to utilize a swap arrangement to hedge against interest rate variability associated with $350,000 of the $390,000 outstanding under the Term Loan Facility. The Company has designated its interest rate swap agreement as a cash flow hedging derivative. To the extent the derivative instrument is effective and the documentation requirements have been met, changes in fair value are recognized in other comprehensive income (loss) (“OCI”) until the underlying hedged item is recognized in earnings. The total fair value of the contract was a net loss of $9,694 at June 30, 2020.
Financial Instruments Disclosures
Fair Value—Financial instruments are required to be categorized within a valuation hierarchy based upon the lowest level of input that is significant to the fair value measurement. The three levels of the valuation hierarchy are as follows:
•Level 1—Fair value is based on quoted prices in active markets.
•Level 2—Fair value is based on internally developed models that use, as their basis, readily observable market parameters. Our derivative positions are classified within level 2 of the valuation hierarchy as they are valued using quoted market prices for similar assets and liabilities in active markets. These level 2 derivatives are valued utilizing an income approach, which discounts future cash flow based on current market expectations and adjusts for credit risk.
•Level 3—Fair value is based on internally developed models that use, as their basis, significant unobservable market parameters. The Company did not have any level 3 classifications at June 30, 2020 or December 31, 2019.
The following table presents the fair value of the interest rate derivative by valuation hierarchy and balance sheet classification:

|  | June 30, 2020 |  |  |  |  |  |  |  | December 31, 2019 |  |  |  |  |  |

The carrying values of the Company's cash and cash equivalents, accounts receivable and accounts payable approximate their fair values because of the short-term nature of these instruments. At June 30, 2020, the fair value of the term loan, based upon the current market rates for debt with similar credit risk and maturities, approximated its carrying value as interest is based on LIBOR plus an applicable margin.
OCI—The following table presents the total value recognized in OCI and reclassified from accumulated other comprehensive income (loss) (“AOCI”) into earnings during the three and six months ended June 30, 2020 for derivatives designated as cash flow hedges:

|  | Three Months Ended June 30, 2020 |  |  |  |  |  | Six Months Ended June 30, 2020 |  |  |  |
|  | Before Tax Amount |  | Tax Amount |  | Net of Tax Amount |  | Before Tax Amount |  | Tax Amount |  | Net of Tax Amount

(1) Net unrealized losses totaling $4,683 are anticipated to be reclassified from AOCI into earnings during the next 12 months due to settlement of the associated underlying obligations.

12. | COMMITMENTS AND CONTINGENCIES

The Company is required by its insurance providers to obtain and hold standby letters of credit. These letters of credit serve as a guarantee by the banking institution to pay the Company’s insurance providers the incurred claim costs attributable to its general liability, workers compensation and automobile liability claims, up to the amount stated in the standby letters of credit, in the event that these claims were not paid by the Company. These letters of credit are cash collateralized, resulting in the cash being designated as restricted.
The Company, including its construction joint ventures and its consolidated 50% owned subsidiaries, is now and may in the future be involved as a party to various legal proceedings that are incidental to the ordinary course of business. Management, after consultation with legal counsel, does not believe that the outcome of these actions will have a material impact on the Condensed Consolidated Financial Statements of the Company.

13. | INCOME TAXES

The Company and its subsidiaries are based in the U.S. and file federal and various state income tax returns. The components of the provision for income taxes were as follows:

| Three Months Ended June 30, |  |  |  | Six Months Ended June 30, |  |
| 2020 |  | 2019 |  | 2020 |  | 2019
Current tax expense | $ | 1,938 |  |  | $ | 86 |  |  | $ | 2,209 |  |  | $ | 108 |
Deferred tax expense | 5,310 |  |  | 620 |  |  | 6,223 |  |  | 761 |
Income tax expense | $ | 7,248 |  |  | $ | 706 |  |  | $ | 8,432 |  |  | $ | 869 |
Cash paid for income taxes | $ | — |  |  | $ | — |  |  | $ | 44 |  |  | $ | — |

The effective income tax rate varied from the 21% federal statutory rate primarily as a result of the change in tax valuation allowance, state income taxes and net income attributable to noncontrolling interest owners which is taxable to those owners rather than to the Company and other permanent differences. In addition, 2019 included a reduction in the tax valuation allowance that reduced income tax expense and 2020 includes state taxes related to Plateau.
Due to the net operating loss carryforwards, the Company expects no cash payments for federal income taxes for 2020 or 2019. The Company makes cash payments for state income taxes in states in which the Company does not have net operating loss carry forwards.
At December 31, 2019 the Company had federal and state net operating loss (“NOL”) carryforwards of $83,270 and $44,857, respectively, which expire at various dates in the next 18 years for U.S. federal income tax and in the next 8 to 18 years for the various state jurisdictions where we operate. Such NOL carryforwards expire beginning in 2028 through 2038.
As a result of the Company’s analysis, management has determined that the Company does not have any material uncertain tax positions.

14. | STOCK INCENTIVE PLAN AND OTHER EQUITY ACTIVITY

General—The Company has a stock incentive plan (the “Stock Incentive Plan”) and a employee stock purchase plan (the “ESPP”) that are administered by the Compensation and Talent Development Committee of the Board of Directors. Under the Stock Incentive Plan, the Company can issue shares to employees and directors in the form of restricted stock awards (“RSAs”), restricted stock units (“RSUs”) and performance share units (“PSUs”). Changes in common stock, additional paid in capital and treasury stock during the six months ended June 30, 2020 primarily relate to activity associated with the Stock Incentive Plan, the ESPP, and share repurchases.
Share Grants—During the six months ended June 30, 2020, the Company had the following share grants associated with the Stock Incentive Plan:

|  | Shares |  | Weighted Average Grant-Date Fair Value per Share

The Company recognizes forfeitures as they occur, rather than estimating expected forfeitures. Included within total stock-based compensation expense for the three and six months ended June 30, 2020 is $18 and $36, respectively, of expense related to the ESPP. At June 30, 2020, 762 authorized shares remained available for issuance under the ESPP.

OVERVIEW
General—Sterling Construction Company, Inc. (“Sterling” or “the Company”), is a construction company that has been involved in the construction industry since its founding in 1955. The Company operates through a variety of subsidiaries within three operating groups specializing in heavy civil, specialty services, and residential projects in the United States (the “U.S.”), primarily across the southern U.S., the Rocky Mountain States, California and Hawaii, as well as other areas with strategic construction opportunities. Heavy civil includes infrastructure and rehabilitation projects for highways, roads, bridges, airfields, ports, light rail, water, wastewater and storm drainage systems. Specialty services projects include construction site excavation and drainage, drilling and blasting for excavation, foundations for multi-family homes, parking structures and other commercial concrete projects. Residential projects include concrete foundations for single-family homes.
Plateau Acquisition—On October 2, 2019, the Company consummated the acquisition of Plateau and entered into a credit agreement with the financial institutions from time to time party thereto as lenders, BMO Harris Bank N.A., as administrative agent, Bank of America, N.A., as syndication agent, and BMO Capital Markets Corp. and BofA Securities, Inc., as joint lead arrangers and joint book runners. The Credit Agreement provides the Company with senior secured debt financing in an amount up to $475 million in the aggregate with a maturity date of October 2, 2024. With the acquisition of Plateau, we now have three reportable segments: Heavy Civil, Specialty Services and Residential. Refer to Note 9 - Debt for a discussion of our financing arrangements and Note 16 - Segment Information for a discussion of reportable segments and related financial information.
Impact of COVID-19—On March 11, 2020, the World Health Organization declared the outbreak of COVID-19 as a pandemic, and on March 13, 2020, the U.S. President announced a National Emergency relating to COVID-19. Federal, state, and local authorities have advised social distancing and many imposed shelter-in-place and stay-at-home orders, including some mandatory business closures. Although authorities in some areas of the U.S. began to relax these quarantine and isolation measures, a recent resurgence of COVID-19 infections in many regions of the country, including some areas where the Company does business, has, in some cases caused authorities to either defer the phasing out of these restrictions, or re-impose quarantine and isolation measures. The impact from the rapidly changing market and economic conditions due to the COVID-19 pandemic remains uncertain, but these conditions have already had, and are expected to continue to have, serious adverse effects on the U.S. and global economies. The Company continues to closely monitor the actual and expected impacts of the COVID-19 pandemic on our business, financial condition and results of operations. Sterling’s business has been identified as a component of “Essential Critical Infrastructure” per the National Cybersecurity and Infrastructure Agency, and to date, we have not experienced significant shutdowns of project sites or operational interruptions. Consistent with governmental orders and public health guidelines, the Company has continued to operate across its footprint. For the Company’s office based personnel, the Company is social distancing and, where practical, working from home. For personnel onsite at the Company’s construction sites, the Company has taken mitigation measures to prevent the spread of COVID-19, including but not limited to, social distancing, wellness checks, providing sanitation stations and wearing personal protective equipment. While the Company has not incurred significant disruptions thus far from the COVID-19 pandemic, the pandemic may impact our business, condensed consolidated results of operations and financial condition in the future. However, the significance of the impact on our operations going forward is not yet certain and depends on numerous evolving factors as discussed further in Part II, Item 1A "Risk Factors" in this Form 10-Q.
MARKET OUTLOOK AND TRENDS
Heavy Civil—Sterling’s heavy civil construction business is primarily driven by federal, state and municipal funding. Federal funds, on average, provide 50% of annual State Department of Transportation (DOT) capital outlays for highway and bridge projects. Several of the states in Sterling’s key markets have instituted actions to further increase annual spending. In November 2018, various state and local transportation measures were passed securing, and in some cases increasing, funding of $1.57 billion in California, $1.27 billion in Texas, $528.5 million in Arizona, $128.2 million in Colorado and $87 million in Utah. In October 2018, the Federal Aviation Administration reauthorized $3.35 billion annually for the next five years. This reauthorization also includes more than $1 billion a year for airport infrastructure grants and about $1.7 billion for disaster relief. In addition to the state locally funded actions, this is the final year of the five-year $305 billion 2015 federally funded Fixing America’s Surface Transportation (“FAST”) Act that increased the annual federal highway investment by 15.1% over the five-year period from 2016 to 2020. With the FAST Act set to expire this year, the federal government is currently working towards a bipartisan Federal Infrastructure Bill (America’s Transportation Infrastructure Act) that would both increase and solidify funding for the next five years. Should the federal government approve this incremental infrastructure investment, it would be an additional growth catalyst; however, it would be unlikely to create a significant business impact before late 2020 or 2021. The Heavy Civil segment continues to see an unfavorable productivity impact related to the pandemic as customers and back offices began to work virtually and new procedures and protocol were developed and implemented into field operations beginning in the first quarter of 2020.
24

Specialty Services—Sterling’s specialty services business is primarily driven by investments from end users and developers. Key end users, including Amazon and Home Depot, have begun implementing publicly announced multi-year capital infrastructure campaigns. In our primary market in the southeastern United States, and specifically Georgia, the availability rate remains low and positive new square footage development trends continue. In our key commercial markets forecasted net absorption continues to be positive, with more space leased than supplied to the market. Additionally, the lending environment continues to sustain new development within our specialty services space. However, the outlook for multifamily vacancy rate continues to be below its long-term average and we are experiencing a slowdown in investment in this space.
Residential—The Company’s residential construction business is directly related to new home starts in its key markets. The Company’s core customer base is primarily made up of leading national home builders as well as regional and custom home builders. The Company has continued its expansion of its residential business into the Houston market. Although our customers anticipated a slowdown in the housing market and demand for new developments for the second quarter of 2020, our actual revenues exceeded those expectations. However, due to the recent resurgence of COVID-19 infections, we may still experience a slowdown in the demand for new developments in future periods.
BACKLOG
At June 30, 2020, our Backlog of construction projects, made up of our Heavy Civil and Specialty Services segments, was $1.13 billion, as compared to $1.07 billion at December 31, 2019. The contracts in Backlog are typically completed in 6 to 36 months. Contracts in which we are the apparent low bidder for projects (“Unsigned Low-bid Awards”) are excluded from Backlog until the contract is executed by our customer. Unsigned Low-bid Awards were $437 million at June 30, 2020 and $273 million at December 31, 2019. The combination of our Backlog and Unsigned Low-bid Awards, which we refer to as “Combined Backlog” totaled $1.57 billion and $1.34 billion as of June 30, 2020 and December 31, 2019, respectively.
The Company’s margin in Backlog has increased from 11.5% at December 31, 2019 to 12.9% at June 30, 2020 and the Combined Backlog margin increased from 11.0% at December 31, 2019 to 11.7% at June 30, 2020, driven by a greater mix of Specialty Services awards.
RESULTS OF OPERATIONS

25

Revenues—Revenues were $400.0 million for the second quarter of 2020, an increase of $136.0 million or 51.5% compared with the second quarter of 2019. The increase in the second quarter of 2020 was driven by a $107.8 million increase in Specialty Services due to the inclusion of the full quarter results from Plateau, which was acquired on October 2, 2019, a $20.2 million increase in Heavy Civil, and a $7.9 million increase in Residential. Revenues were $696.7 million for the six months ended June 30, 2020, an increase of $208.7 million or 42.8% compared with the six months ended June 30, 2019. The increase in the six months ended June 30, 2020 was driven by a $181.9 million increase in Specialty Services due to the inclusion of six months of results from Plateau, a $25.3 million increase in Heavy Civil, and a $1.5 million increase in Residential.
Gross profit—Gross profit was $59.6 million for the second quarter of 2020, an increase of $34.1 million or 133.7% compared to the second quarter of 2019. The Company’s gross margin as a percent of revenue increased to 14.9% in the second quarter of 2020, as compared to 9.7% in the second quarter of 2019. The increases in gross profit and gross margin as a percent of revenue are primarily driven by Specialty Services due to the inclusion of a full quarter results from Plateau. Additionally, Heavy Civil and Residential also reported higher gross profit and gross margin as a percent of revenue compared to the second quarter of 2019. Gross profit was $94.8 million for the six months ended June 30, 2020, an increase of $49.8 million or 110.7% compared with the six months ended June 30, 2019. The Company’s gross margin as a percent of revenue increased to 13.6% in the six months ended June 30, 2020, as compared to 9.2% in the six months ended June 30, 2019. The increase in gross profit and gross margin as a percent of revenue are primarily driven by Specialty Services due to the inclusion of six months of results from Plateau operations in 2020.
Contracts in progress which were not substantially completed totaled approximately 210 and 130 at June 30, 2020 and 2019, respectively. These contracts are of various sizes, of different expected profitability and in various stages of completion. The nearer a contract progresses toward completion, the more visibility the Company has in refining its estimate of total revenues (including incentives, delay penalties, and change orders), costs and gross profit. Thus, gross profit as a percent of revenues can increase or decrease from comparable and subsequent quarters due to variations among contracts and depending upon the stage of completion of contracts.
General and administrative expenses—General and administrative expenses were $18.5 million for the second quarter of 2020, an increase of $8.3 million compared to the second quarter of 2019. General and administrative expenses were $36.1 million for the six months ended June 30, 2020, an increase of $14.0 million compared to the six months ended June 30, 2019. These increases were primarily due to the inclusion of the results from Plateau operations in 2020 and higher stock compensation and other corporate related cost.
Intangible asset amortization—Intangible asset amortization was $2.9 million for the second quarter of 2020, an increase of $2.3 million compared to the second quarter of 2019. Intangible asset amortization was $5.7 million for the six months ended June 30, 2020, an increase of $4.5 million compared to the six months ended June 30, 2019. The increases were a result of the Plateau Acquisition.
Acquisition related costs—The Company had acquisition related costs of $0.1 million and $0.3 million during the second quarter of 2020 and 2019, respectively, and $0.6 million and $0.3 million for the six months ended June 30, 2020 and 2019, respectively, all of which related to the Plateau Acquisition.
Other operating expense, net—Other operating expense, net, includes 50% of earnings and losses related to Members’ interest of consolidated 50% owned subsidiaries (included within Heavy Civil), earn-out expense, and other miscellaneous operating income or expense. Members’ interest earnings are treated as an expense and increase the liability account. The change in other operating expense, net, was $1.8 million during the second quarter of 2020 compared to the second quarter of 2019. Earn-out expense was $0.5 million for both the second quarter of 2020 and 2019. Members’ interest earnings increased by $1.8 million during the second quarter of 2020 to $4.6 million from $2.8 million in the second quarter of 2019. The change in other operating expense, net, was $1.8 million during the six months ended June 30, 2020 compared to the six months ended June 30, 2019. Earn-out expense was $1.0 million for the six months ended June 30, 2020, compared to $1.5 million in the six months ended June 30, 2019. Members’ interest earnings increased by $2.2 million during the six months ended June 30, 2020 to $6.3 million from $4.1 million in the six months ended June 30, 2019.
Interest expense—Interest expense was $7.6 million in the second quarter of 2020 compared to $2.9 million in the second quarter of 2019 and interest expense was $15.4 million in the six months ended June 30, 2020 compared to $6.0 million in the six months ended June 30, 2019. The increases were due to borrowings related to the Plateau Acquisition.
Income taxes—The effective income tax rate was 28.4% and 28.2% in the second quarter of 2020 and the six months ended June 30, 2020, respectively, compared to 8.2% in both the second quarter of 2019 and the six months ended June 30, 2019. The increases in both periods are in part due to a reduction in the tax valuation allowance that reduced the effective income tax rate in 2019 and in part due to additional state taxes in 2020 primarily related to Plateau. Due to its net operating loss carryforwards,
26

the Company expects no cash payments for federal income taxes for 2020 or 2019. See Note 13 - Income Taxes for more information.

Heavy Civil
Revenues—Revenues were $220.4 million for the second quarter of 2020, an increase of $20.2 million or 10.1% compared to the second quarter of 2019. The increase was driven by higher heavy highway revenue for the second quarter of 2020 compared to the second quarter of 2019. Revenues were $376.1 million for the six months ended June 30, 2020, an increase of $25.3 million or 7.2% compared to the six months ended June 30, 2019. The increase was driven by higher heavy highway revenue for the six months ended June 30, 2020 compared to the six months ended June 30, 2019.
Operating Income—Operating income was $3.9 million for the second quarter of 2020, a decrease of $1.8 million, compared to the second quarter of 2019. The decrease was the result of greater project mix shift to our 50% owned subsidiaries which increased members interest expense by $1.8 million and additional costs associated with COVID-19 pandemic impacts. Operating income was $0.3 million for the six months ended June 30, 2020, a decrease of $3.3 million, compared to the six months ended June 30, 2019. The decrease was the result of the aforementioned second quarter impact and first quarter seasonality which drove lower absorption of fixed costs.
Specialty Services
Revenues—Revenues were $135.7 million for the second quarter of 2020, an increase of $107.8 million compared to the second quarter of 2019. The increase was driven by the inclusion of three months of revenue from Plateau operations in the second quarter of 2020 and increased Commercial revenues. Revenues were $240.4 million for the six months ended June 30, 2020, an increase of $181.9 million compared to the second quarter of 2019. The increase was primarily attributable to the inclusion of six months of revenue from Plateau operations in 2020.
Operating income—Operating income was $23.2 million for the second quarter of 2020, an increase of $22.3 million, compared to the second quarter of 2019 and operating income was $34.4 million for the six months ended June 30, 2020, an increase of $32.4 million, compared to the six months ended June 30, 2019. The increases were primarily attributable to the inclusion of operating income generated from Plateau operations in 2020.
Residential
Revenues—Revenues were $43.9 million for the second quarter of 2020, an increase of $7.9 million or 22.1%, compared to the second quarter of 2019. The increase in revenue was a result of heavy rainfall in the first quarter of 2020 which pushed work on our projects and resulting revenues into April of 2020, as well as continued ramp-up of operations in Houston. Revenues were $80.2 million for the six months ended June 30, 2020, an increase of $1.5 million or 1.9%, compared to the six months ended June 30, 2019. The increase in revenue was primarily the result of the continued ramp-up of work in Houston.
27

Operating income—Operating income was $6.0 million for the second quarter of 2020, an increase of $1.2 million, compared to the second quarter of 2019 and operating income was $11.1 million for the six months ended June 30, 2020, an increase of $0.5 million, compared to the six months ended June 30, 2019. The increase was driven by the ramp-up of operations and scale in Houston. Houston as a percentage of completed slabs was 14% for the second quarter of 2020 compared to 6% for the second quarter of 2019. Operating income as a percent of revenue increased 40 basis points compared to the second quarter of 2019 and the six months ended June 30, 2019, driven by the ramp-up of operations and scale in Houston.
LIQUIDITY AND SOURCES OF CAPITAL
Cash—Cash at June 30, 2020, was $70.6 million, and includes the following components:

(In thousands) | June 30, 2020 |  | December 31, 2019
Generally Available | $ | 31,760 |  |  | $ | 29,659 |
Consolidated 50% Owned Subsidiaries | 31,346 |  |  | 12,004 |
Construction Joint Ventures | 7,506 |  |  | 4,070 |
Total Cash | $ | 70,612 |  |  | $ | 45,733 |

The following tables set forth information about our cash flows and liquidity:

| Six Months Ended June 30, |  |
(In thousands) | 2020 |  | 2019
Net cash provided by (used in): |  |  |
Operating activities | $ | 52,261 |  |  | $ | (4,325) |
Investing activities | (13,805) |  |  | (4,052) |
Financing activities | (13,577) |  |  | (13,988) |
Net change in cash and cash equivalents | $ | 24,879 |  |  | $ | (22,365) |

Operating Activities—During the six months ended June 30, 2020, net cash provided by operating activities was $52.3 million compared to net cash used of $4.3 million in the six months ended June 30, 2019. Cash flows provided by operating activities were driven by net income, adjusted for various non-cash items and changes in accounts receivable, net contracts in progress and accounts payable balances (collectively, “Contract Capital”), as discussed below, and other accrued liabilities.
Changes in Contract Capital—The change in operating assets and liabilities varies due to fluctuations in operating activities and investments in Contract Capital. The changes in the components of Contract Capital during the six months ended June 30, 2020 and 2019 were as follows:

| Six Months Ended June 30, |  |
(In thousands) | 2020 |  | 2019
Costs and estimated earnings in excess of billings | $ | (9,513) |  |  | $ | (12,354) |
Billings in excess of costs and estimated earnings | 25,923 |  |  | (1,836) |
Contracts in progress, net | 16,410 |  |  | (14,190) |
Accounts receivable, including retainage | (21,159) |  |  | (12,787) |
Receivables from and equity in construction joint ventures | (3,200) |  |  | (3,661) |
Accounts payable | (6,495) |  |  | 1,916 |
Change in Contract Capital, net | $ | (14,444) |  |  | $ | (28,722) |

During the six months ended June 30, 2020, the change in Contract Capital decreased liquidity by $14.4 million. The Company’s Contract Capital fluctuations are impacted by the mix of projects in Backlog, seasonality, the timing of new awards, and related payments for work performed and the contract billings to the customer as projects are completed. Contract Capital is also impacted at period-end by the timing of accounts receivable collections and accounts payable payments for projects.
Investing Activities—During the six months ended June 30, 2020, net cash used in investing activities was $13.8 million compared to $4.1 million in the six months ended June 30, 2019. The use of cash was driven by purchases of capital equipment and buildings and improvements. Capital equipment is acquired as needed to support changing levels of production activities and to replace retiring equipment.
28

Financing Activities—During the six months ended June 30, 2020, net cash used in financing activities was $13.6 million compared to net cash used of $14.0 million in the prior year. The financing cash outflow was driven by $22.6 million of repayments on debt, primarily consisting of $12.5 million in payments on the combined promissory notes and deferred cash payments issued as part of the Tealstone Acquisition and $10.0 million in repayments on the Term Loan Facility.
Capital Strategy—The Company will continue to explore additional revenue growth and capital alternatives to improve leverage and strengthen its financial position in order to take advantage of trends in the civil infrastructure and specialty services markets. The Company expects to pursue strategic uses of its cash, such as, investing in projects or businesses that meet its gross margin targets and overall profitability and managing its debt balances.
OFF-BALANCE SHEET ARRANGEMENTS AND JOINT VENTURES
We participate in various construction joint venture partnerships in order to share expertise, risk and resources for certain highly complex projects. The joint venture’s contract with the project owner typically requires joint and several liability among the joint venture partners. Although our agreements with our joint venture partners provide that each party will assume and fund its share of any losses resulting from a project, if one of our partners was unable to pay its share, we would be fully liable for such share under our contract with the project owner. Circumstances that could lead to a loss under these guarantee arrangements include a partner’s inability to contribute additional funds to the venture in the event that the project incurred a loss or additional costs that we could incur should the partner fail to provide the services and resources toward project completion that had been committed to in the joint venture agreement. See the 2019 Form 10-K under “Part I, Item 1A. Risk Factors,” as updated herein.
At June 30, 2020, there was approximately $625.1 million of construction work to be completed on unconsolidated construction joint venture contracts, of which $278.8 million represented our proportionate share. Due to the joint and several liability under our joint venture arrangements, if one of our joint venture partners fails to perform, we and the remaining joint venture partners would be responsible for completion of the outstanding work. As of June 30, 2020, we are not aware of any situation that would require us to fulfill responsibilities of our joint venture partners pursuant to the joint and several liability under our contracts.
NEW ACCOUNTING STANDARDS
See the applicable section of Note 2 - Basis of Presentation and Significant Accounting Policies for a discussion of new accounting standards.
CRITICAL ACCOUNTING ESTIMATES
The discussion and analysis of the financial condition and results of operations are based on the Company’s Condensed Financial Statements, which have been prepared in accordance with U.S. GAAP. The preparation of these Condensed Financial Statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosures of contingent assets and liabilities. The Company continually evaluates its estimates based on historical experience and various other assumptions that the Company believes to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. The Company believes the following critical accounting policies involve more significant judgments and estimates used in the preparation of the Condensed Financial Statements.
Revenue Recognition
Performance Obligations Satisfied Over Time—Revenue for contracts that satisfy the criteria for over time recognition is recognized as the work progresses. The Company measures transfer of control of the performance obligation utilizing the cost-to-cost measure of progress, with cost of revenue including direct costs, such as materials and labor, and indirect costs that are attributable to contract activity. Under the cost-to-cost approach, the use of estimated costs to complete each performance obligation is a significant variable in the process of determining recognized revenue and is a significant factor in the accounting for such performance obligations. Significant estimates that impact the cost to complete each performance obligation are: materials, components, equipment, labor and subcontracts; labor productivity; schedule durations, including subcontractor or supplier progress; contract disputes, including claims; achievement of contractual performance requirements; and contingency, among others. The cumulative impact of revisions in total cost estimates during the progress of work is reflected in the period in which these changes become known, including, to the extent required, the reversal of profit recognized in prior periods and the recognition of losses expected to be incurred on performance obligations in progress. Due to the various estimates inherent in our contract accounting, actual results could differ from those estimates, which could result in material changes to the Company’s Condensed Financial Statements and related disclosures.
29

Valuation of Long-Lived Assets
Long-lived assets, which include property, equipment and acquired intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If a recoverability assessment is required, the estimated future cash flow associated with the asset or asset group will be compared to their respective carrying amounts to determine if an impairment exists. Actual useful lives and cash flows could be different from those estimated by management, and this could have a material effect on operating results and financial position. For the three and six months ended June 30, 2020 and the year ended December 31, 2019, there were no events or changes in circumstances that would indicate a material impairment of our long-lived assets.
Goodwill
At June 30, 2020 and December 31, 2019, we had goodwill with a carrying amount of $192.0 million and $191.9 million, respectively. Goodwill is not amortized to earnings, but instead is reviewed for impairment at least annually, absent any indicators of impairment or when other actions require an impairment assessment. The Company performs the annual impairment assessment during the fourth quarter of each year based on balances as of October 1. During the fourth quarter 2019, the Company performed a qualitative assessment of goodwill, and based on this assessment, no indicators of impairment were present. Additionally, during the three and six months ended June 30, 2020, the Company noted no indicators of impairment.
Income Taxes
Deferred Tax Realization Assessments—Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis using currently enacted income tax rates for the years in which the differences are expected to reverse. A valuation allowance is provided to offset any net deferred tax assets (“DTA(s)”) if, based upon the available evidence, it is more likely than not that some or all of the DTAs will not be realized. The realization of our net DTAs depends upon our ability to generate sufficient future taxable income of the appropriate character and in the appropriate jurisdictions.
As a result of the Company’s analysis, management has determined that the Company does not have any material uncertain tax positions. If our estimates or assumptions regarding our current and deferred tax items are inaccurate or are modified, these changes could have potentially material impacts on our earnings.
Purchase Accounting Estimates
The aggregate purchase price for the Plateau Acquisition was allocated to the major categories of assets and liabilities acquired based upon their estimated fair values as of October 2, 2019, which were based, in part, upon an external preliminary appraisal and valuation of certain assets, including specifically identified intangible assets and property and equipment. The excess of the purchase price over the preliminary estimated fair value of the net tangible and identifiable intangible assets acquired, totaling $106.8 million, was recorded as goodwill. The purchase price allocation is subject to further change when additional information is obtained. We intend to finalize the purchase price allocation as soon as practicable within the measurement period, but no later than one year following the closing date of the Plateau Acquisition. Our final purchase price allocation may result in additional adjustments to various other assets and liabilities, including the residual amount allocated to goodwill during the measurement period. See Note 3 - Plateau Acquisition to our Condensed Financial Statements for further discussion.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
Interest Rate Risk
We continue to utilize a swap arrangement to hedge against interest rate variability associated with $350,000 of the $390,000 outstanding under the Term Loan Facility. The Company has designated its interest rate swap agreement as a cash flow hedging derivative. To the extent the derivative instrument is effective and the documentation requirements have been met, changes in fair value are recognized in other comprehensive income (loss) until the underlying hedged item is recognized in earnings. The total fair value of the contract was a net loss of approximately $9.7 million at June 30, 2020. For the $40 million remaining portion of the Term Loan Facility not associated with the interest rate swap hedge and the $20 million of the Revolving Credit Facility, at June 30, 2020 a 100-basis point (or 1%) increase or decrease in the interest rate would increase or decrease interest expense by approximately $0.6 million per year.
30

Other
The carrying values of the Company’s cash and cash equivalents (primarily consisting of bank deposits), accounts receivable and accounts payable approximate their fair values because of the short-term nature of these instruments. At June 30, 2020, the fair value of the term loan, based upon the current market rates for debt with similar credit risk and maturities, approximated its carrying value as interest is based on LIBOR plus an applicable margin.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Disclosure controls and procedures include, but are not limited to, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to the issuer’s management, including the principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.
The Company’s principal executive officer and principal financial officer reviewed and evaluated the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of June 30, 2020. As previously disclosed, we completed the Plateau Acquisition on October 2, 2019 and, as permitted by SEC guidance for newly acquired businesses, we have elected to exclude the acquired operations of Plateau from the scope of design and operation of our disclosure controls and procedures for the quarter ended June 30, 2020. Based on that evaluation, the Company’s principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures were effective at June 30, 2020 to ensure that the information required to be disclosed by the Company in this Report is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and is accumulated and communicated to the Company’s management including the principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.
Changes in Internal Control over Financial Reporting
There have been no changes in internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during the quarter ended June 30, 2020 that have materially affected, or are reasonably likely to materially affect, internal control over financial reporting.
Inherent Limitations on Effectiveness of Controls
Internal control over financial reporting may not prevent or detect all errors and all fraud. Also, projections of any evaluation of effectiveness of internal control 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.
PART II—OTHER INFORMATION
Item 1. Legal Proceedings
The Company, including its construction joint ventures and its consolidated 50% owned subsidiaries, is now and may in the future be involved as a party to various legal proceedings that are incidental to the ordinary course of business. The Company regularly analyzes current information about these proceedings and, as necessary, provides accruals for probable liabilities on the eventual disposition of these matters.
In the opinion of management, after consultation with legal counsel, there are currently no threatened or pending legal matters that would reasonably be expected to have a material adverse impact on the Condensed Consolidated Results of Operations, Financial Position or Cash Flows.
Item 1A. Risk Factors
There have not been any material changes from the risk factors previously disclosed in “Part I, Item 1A. Risk Factors” of the 2019 Form 10-K, except as provided below. In addition, many of the other risks described in Part I, Item 1A. “Risk Factors” of our 2019 Form 10-K may be heightened by the risks described below as well as other impacts of COVID-19 or other global or regional health pandemics, epidemics or similar public health threats. The below discussion of risk factors contains forward-looking statements. These risk factors may be important to understanding other statements in this Report and the 2019 Form 10-K. The below information should be read in conjunction with the risk factors previously disclosed in “Part I, Item 1A. Risk Factors” of the 2019 Form 10-K, as updated by Part I, Item 1A. Risk Factors” of our quarterly report on Form 10-Q for the quarter ended March 31, 2020, and with the other portions of this Report, including “Cautionary Statement Regarding Forward-Looking Statements,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in
31

Item 2 of Part I and the Condensed Financial Statements and related notes in Item 1 of Part I. You should carefully consider such risk factors, which could materially affect the business, financial condition or future results.
Risk Related to the COVID-19 Pandemic
The COVID-19 pandemic could disrupt the Company’s operations and adversely affect its business, results of operations, and financial condition.
On March 11, 2020, the World Health Organization declared the outbreak of COVID-19 as a pandemic, and on March 13, 2020, the U.S. President announced a National Emergency relating to COVID-19. Federal, state, and local authorities have advised social distancing and many imposed shelter-in-place and stay-at-home orders, including some mandatory business closures. Although authorities in some areas of the U.S. began to relax these quarantine and isolation measures, a recent resurgence of COVID-19 infections in many regions of the country, including some areas where the Company does business, has, in some cases caused authorities to either defer the phasing out of these restrictions, or re-impose quarantine and isolation measures. The impact from the rapidly changing market and economic conditions due to the COVID-19 pandemic remains uncertain, but these conditions have already had, and are expected to continue to have, serious adverse effects on the U.S. and global economies. This outbreak, which has continued to spread worldwide, has adversely affected workforces, customers, economies, and financial markets globally. While we have not incurred significant disruptions thus far from the COVID-19 outbreak, the pandemic may impact our business, condensed consolidated results of operations and financial condition in the future. However, the significance of the impact on the Company's operations, if any, is not yet certain and depends on numerous evolving factors that the Company may not be able to accurately predict or effectively respond to, including, without limitation: the duration and scope of the outbreak; actions taken by governments, businesses, and individuals in response to the outbreak; the effect on economic activity and actions taken in response; the effect on customers and their demand for the Company's products and services; the ability of our subcontractors to perform under their contracts due to their own financial or operational difficulties; the availability of subcontractors and other talent; and the Company's ability to continue operations, including without limitation as a result of supply chain challenges, facility closures, social distancing, restrictions on travel, fear or anxiety by the populace and shelter-in-place orders.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
The following table shows shares repurchased from employees holding shares of the Company’s common stock that had been awarded to them by the Company and that were released from Company-imposed transfer restrictions. The repurchase was to enable the employees to satisfy the Company’s tax withholding obligations occasioned by the release of the restrictions. The repurchase was made at the election of the employees pursuant to a procedure adopted by the Compensation and Talent Development Committee of the Board of Directors.
