Business Summary

Sterling Construction Company, Inc. (“Sterling” or “the Company”), a Delaware corporation, is a construction company that specializes in heavy civil construction and residential concrete projects, primarily in Arizona, California, Colorado, Hawaii, Nevada, Texas, Utah and other states in which there are feasible construction opportunities. Our heavy civil construction projects include highways, roads, bridges, airfields, ports, light rail, water, wastewater and storm drainage systems, foundations for multi-family homes, commercial concrete projects and parking structures. Our residential construction projects include concrete foundations for single-family homes.

Presentation

The condensed consolidated financial statements included herein have been prepared by Sterling, without audit, in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and should be read in conjunction with the Annual Report on Form 10-K for the year ended December 31, 2017 (“2017 Form 10-K”). Certain information and note disclosures prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been either condensed or omitted pursuant to SEC rules and regulations. The condensed consolidated financial statements reflect, in the opinion of management, all normal recurring adjustments necessary to present fairly the Company’s financial position at March 31, 2018 and the results of operations and cash flows for the periods presented. The December 31, 2017 condensed consolidated balance sheet data herein was derived from audited financial statements, but as discussed above, does not include all disclosures required by GAAP. Interim results may be subject to significant seasonal variations and the results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results expected for the full year or subsequent quarters.

Use of Estimates

The preparation of the accompanying condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions 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 of the Company’s accounting policies require higher degrees of judgment than others in their application. These include the recognition of revenue and earnings from construction contracts over time, the valuation of long-term assets, income taxes, and purchase accounting, including intangibles and goodwill. 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

The Company’s significant accounting policies are more fully described in Note 1 of the Notes to Consolidated Financial Statements in the 2017 Form 10-K. There have been no material changes to significant accounting policies since December 31, 2017.

Principles of Consolidation

The accompanying condensed consolidated financial statements include the accounts of subsidiaries and construction joint ventures in which the Company has 50% or greater ownership interest or otherwise controls such entities. For investments in construction joint ventures that are not wholly-owned, but where the Company exercises control, the equity held by the remaining owners and their portions of net income (loss) are reflected in the balance sheet line item “Noncontrolling interests” in “Equity” and the statement of operations line item “Noncontrolling interests in earnings,” respectively. For investments in subsidiaries that are not wholly-owned, but where the Company exercises control and where the Company has a mandatorily redeemable interest, the equity held by the remaining owners and their portion of net income (loss) is reflected in the balance sheet line item “Members' interest subject to mandatory redemption and undistributed earnings” and the statement of operations line item “Other operating expense, net” respectively. All significant intercompany accounts and transactions have been eliminated in consolidation.

Where the Company is a noncontrolling joint venture partner, and otherwise not required to consolidate the joint venture entity, its share of the operations of such construction joint venture is accounted for on a pro rata basis in the condensed consolidated statements of operations and as a single line item (“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.

Heavy Civil Construction

The Company engages in various types of heavy civil construction projects principally for public (government) owners. Credit risk is minimal with public owners since the Company ascertains that funds have been appropriated by the governmental project owner prior to commencing work on such projects. While most public contracts are subject to termination at the election of the government entity, in the event of termination the Company is entitled to receive the contract price for completed work and reimbursement of termination-related costs plus a margin. Credit risk with private owners is mitigated by statutory mechanic’s liens, which give the Company high priority in the event of lien foreclosures following financial difficulties of private owners.

Our contracts generally take 12 to 36 months to complete. The Company generally provides a one to two-year warranty for workmanship under its contracts when completed. Warranty claims historically have been insignificant.

Revenues are recognized as performance obligations are satisfied over time (formerly known as percentage-of-completion method), measured by the ratio of costs incurred up to a given date to estimated total costs for each contract. This cost to cost measure is used because management considers it to be the best available measure of progress on these contracts. Contract costs include all direct material, labor, subcontract and other costs and those indirect costs related to contract performance, such as indirect salaries and wages, equipment repairs and depreciation, insurance and payroll taxes. Administrative and general expenses are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. 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.

Changes in estimated revenues and gross margin resulted in a net gain of $1.3 million and $0.8 million during the three months ended March 31, 2018 and 2017, respectively, included in “Operating income (loss)” on the condensed consolidated statements of operations.

Change orders are modifications of an original contract that effectively change the existing provisions of the contract without adding new provisions or terms. Change orders may include changes in specifications or designs, manner of performance, facilities, equipment, materials, sites and period of completion of the work. Either we or our customers may initiate change orders.

The Company considers unapproved change orders to be contract variations for which we have customer approval for a change of scope but a price change associated with the scope change has not yet been agreed upon. Costs associated with unapproved change orders are included in the estimated costs to complete the contracts and are treated as project costs as incurred. The Company recognizes revenue equal to costs incurred on unapproved change orders when management determines approval to be probable. Unapproved change orders involve the use of estimates, and it is reasonably possible that revisions to the estimated costs and recoverable amounts may be required in future reporting periods to reflect changes in estimates or final agreements with customers. Change orders that are unapproved as to both price and scope are evaluated as claims.

The Company considers claims to be amounts in excess of approved contract prices that we seek to collect from our customers or others for customer-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price, or other causes of unanticipated additional contract costs. Claims are included in the calculation of revenue when realization is probable and amounts can be reliably determined to the extent costs are incurred. To support these requirements, the existence of the following items must be satisfied: (i) the contract or other evidence provides a legal basis for the claim; or a legal opinion has been obtained, stating that under the circumstances there is a reasonable basis to support the claim; (ii) additional costs are caused by circumstances that were unforeseen at the contract date and are not the result of deficiencies in the contractor’s performance; (iii) costs associated with the claim are identifiable or otherwise determinable and are reasonable in view of the work performed; and (iv) the evidence supporting the claim is objective and verifiable, not based on management’s feel for the situation or on unsupported representations. Revenue in excess of contract costs incurred on claims is recognized when an agreement is reached with customers as to the value of the claims, which in some instances may not occur until after completion of work under the contract. Costs associated with claims are included in the estimated costs to complete the contracts and are treated as project costs when incurred.

The Company has projects where we are in the process of negotiating, or awaiting final approval of, unapproved change orders and claims with our 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 our 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 our review of the provisions of our contracts, specific costs incurred and other related evidence supporting the unapproved change orders, claims and our entitled unpaid project price, together in some cases as necessary with the views of the Company’s outside claim consultants, we concluded that it was appropriate to include the unapproved change order, claim and entitled unpaid project price amounts of $5.0 million, $6.0 million and $0.0 million, respectively, at March 31, 2018, and $5.0 million, $5.0 million and $0.0 million, respectively, at December 31, 2017, in “Costs and estimated earnings in excess of billings on uncompleted contracts” on our condensed consolidated balance sheets.

We expect these matters will be resolved without a material adverse effect on our financial statements. However, unapproved change order and claim amounts are subject to negotiations which may cause actual results to differ materially from estimated and recorded amounts.

Residential Construction

Residential construction revenue and related profit are recognized when construction on the concrete foundation unit is completed (i.e., at a point in time). The time from starting construction to finishing is typically less than one month.

Recently Adopted Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-9, “Revenue from Contracts with Customers.” We adopted the requirements of the new standard effective January 1, 2018. See Note 3 “Revenue from Contracts with Customers.”

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued its new lease accounting guidance in ASU No. 2016-2, “Leases” (Topic 842). Under the new guidance, lessees will be required to recognize for all leases (with the exception of short-term leases) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. The new standard is effective for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the impact of the adoption of this ASU to the Company’s consolidated financial statements and related disclosures.

In August 2016, the FASB issued guidance in ASU No. 2016-15 (Topic 230): “Classification of Certain Cash Receipts and Cash Payments.” This update addresses specific cash flow issues with the objective of reducing existing diversity in practice. Early adoption is permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company expects to adopt this guidance as required and does not expect a material impact to the Company’s consolidated financial statements.
