NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
March 31,June 30, 2019
($ and share values in thousands, except per share data)
(Unaudited) 
1.SUMMARYNATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIESOPERATIONS
Business Summary
Nature of OperationsSterling Construction Company, Inc. (“Sterling” or “the Company”), a Delaware corporation, is a construction company that specializes in heavy civil infrastructure construction and infrastructure rehabilitation as well as residential construction projects. We operate primarily in Arizona, California, Colorado, Hawaii, Nevada, Texas and Utah, as well as other states in which there are feasible construction opportunities.

Residential construction projects include concrete foundations for single-family homes.
Significant Accounting Policies
2.BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation—The Condensed Consolidated Financial Statements included herein have been prepared by the Company, without audit, in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). 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,June 30, 2019 and the results of operations and cash flows for the periods presented. The December 31, 2018 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, 2019quarters presented are not necessarily indicative of the results expected for the full year or subsequent quarters. Values presented within tables, excluding per share data, are in thousands.
Principles of Consolidation—The accompanying Condensed Consolidated Financial Statements 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 footnote 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.
Consolidated 50% Owned Subsidiaries—The accompanying Condensed Consolidated Financial Statements include the accounts of two subsidiaries in which the Company has 50% ownership interest and exercises control over such entities. Therefore, the Company has consolidated these two entities. Both subsidiaries have individual provisions which, under circumstances that are certain to occur, obligate the Company to purchase each partner’s 50% interests. The Company has classified these obligations as mandatorily redeemable and has recorded a liability in “Members’ interest subject to mandatory redemption and undistributed earnings” on the Condensed Consolidated Balance Sheets. Each partner’s portion of net income (loss) is reflected in the Condensed Consolidated Statements of Operations line item “Other operating expense, net”.
Construction Joint Ventures—In the ordinary course of business, the Company executes specific projects and conducts certain operations through joint venture arrangements (referred to as “joint ventures”). The Company has various ownership interests in these joint ventures, with such ownership typically proportionate to the Company’s decision making and distribution rights.
Each joint venture is assessed at inception and on an ongoing basis as to whether it qualifies as a Variable Interest Entity (“VIE”) under the consolidations guidance in ASC Topic 810. If at any time a joint venture qualifies as a VIE, the Company performs a qualitative assessment to determine whether the Company is the primary beneficiary of the VIE and therefore needs to consolidate the VIE.
If the Company determines it is not the primary beneficiary of the VIE or only has the ability to significantly influence, rather than control the joint venture, it is not consolidated. The Company accounts for unconsolidated joint ventures using 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 a permissible modification of the equity method of accounting which is a common practice in the construction industry.


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 and the valuation of long-term assets, income taxes, and purchase accounting, includinggoodwill, other intangibles and goodwill.income taxes. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.
Reclassification—Reclassifications have been made to historical financial data on the Company’s Condensed Consolidated Financial Statements to conform to the Company’s current year presentation.
Heavy Civil Construction Revenue Recognition—The Company engages in various types of heavy civil construction projects principally for public (government) owners. Revenues are recognized as performance obligations are satisfied over time (formerly known as percentage-of-completion method), using the ratio of costs incurred 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 determined to relate 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, estimated profitability and associated change orders and claims, 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.
Change orders, claims and incentives are generally not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as a modification of the existing contract and performance obligation. Change orders may include changes in specifications or designs, manner of performance, facilities, equipment, materials, sites and period of completion of the work. Either the Company or its customers may initiate change orders. Change orders that are unapproved as to both price and scope are evaluated as claims. The Company estimates variable consideration for a performance obligation at the most likely amount to which the Company expects to be entitled (or the most likely amount the Company expects to incur in the case of liquidated damages), utilizing estimation methods that best predict the amount of consideration to which the Company will be entitled (or will be incurred in the case of liquidated damages). The Company includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. The Company’s estimates of variable consideration and determination of whether to include estimated amounts in transaction price are based largely on an assessment of its anticipated performance and all information (historical, current and forecasted) that is reasonably available to the Company.
The Company considers claims to be amounts in excess of approved contract prices that the Company seeks to collect from its 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. The effect of variable consideration on the transaction price of a performance obligation is recognized as an adjustment to revenue on a cumulative catch-up basis. To the extent unapproved change orders and claims reflected in transaction price (or excluded from transaction price in the case of liquidated damages) are not resolved in the Company’s favor, or to the extent incentives reflected in transaction price are not earned, there could be reductions in, or reversals of, previously recognized revenue.
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.
Contract modifications are routine in the performance of the Company’s contracts. Contracts are often modified to account for changes in the contract specifications or requirements. In most instances, contract modifications are for goods or services that are not distinct, and, therefore, are accounted for as part of the existing contract.
Assurance-type warranties are the only warranties provided by the Company and, as such, the Company does not recognize revenue on warranty-related work. The Company generally provides a one to two year warranty for workmanship under its contracts when completed. Warranty claims historically have been insignificant.
Pre-contract costs are generally charged to expense as incurred, but in certain cases their recognition may be deferred if specific probability criteria are met. The Company had no significant deferred pre-contract costs at March 31,June 30, 2019.


Residential Construction Revenue Recognition—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.
Leases—Effective January 1, 2019, the Company determines if an arrangement is a lease at inception. The operating lease right-of-use (“ROU”) assets are included within the Company’s other non-current assets and lease liabilities are included in current or noncurrentnon-current liabilities on the Company’s Condensed Consolidated Balance Sheets. Finance leases are included in property and equipment, current maturities of long-term debt, and long-term debt net of current maturities on the Company’s Condensed Consolidated Balance Sheets.
ROU assets represent the Company’s right to use, or control the use of, a specified asset for the lease term. Lease liabilities are the Company’s obligation to make lease payments arising from a lease, and are measured on a discounted basis. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term on the commencement date. As most of the Company’s leases do not provide an implicit rate, the Company’s incremental borrowing rate was used based on the information available on the commencement date in determining the present value of lease payments. For future leases, the implied rate in the lease will be used to determine the present value. The operating lease ROU asset includes any lease payments made and initial direct costs incurred and excludes lease incentives. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments continues to be recognized on a straight-line basis over the lease term.
Restricted cash—Restricted cash of approximately $3,200 and $3,900 is included in “Other current assets” on the Condensed Consolidated Balance Sheets at June 30, 2019 and December 31, 2018. This 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 Guidance—Guidance
Leases—In February 2016, the Financial Accounting Standards Board (“FASB”) issued its new lease accounting guidance in ASU 2016-2, “Leases” (ASC 842). Under the new guidance, lessees are required to recognize all leases (with the exception of short-term leases) on the balance sheet.
The Company adopted ASC 842 effective January 1, 2019 using the modified retrospective method. The new guidance has been applied to leases that exist or were entered into on or after January 1, 2019 without adjusting comparative periods in the financial statements.
As an accounting policy, the Company has elected not to apply the recognition requirements to short-term leases (leases with terms of 12 months or less). Instead, the Company recognizes the lease payments in the consolidatedCondensed Consolidated Statement of Operations on a straight-line basis over the lease term and variable lease payments in the period in which the obligation for those payments is incurred.
 The Company has elected to utilize the package of practical expedients that allows entities to not reassess 1) the classification of leases existing at the date of adoption;adoption 2) the initial direct costs for any existing leases;leases and 3) whether any expired or existing contracts are or contain leases.
At January 1, 2019, the Company recorded an ROU asset, current maturity of operating lease liability and long-term operating lease liability of $13,600, $6,200 and $7,400, respectively on its consolidated balance sheet,Condensed Consolidated Balance Sheet, related to its existing operating leases. The adoption of this standard did not have a material impact on the Company’s Condensed Consolidated Statements of Operations. As of March 31,June 30, 2019, the weighted average remaining lease terms for the Company’s various operating leases extends out over the next 2.92.8 years. The weighted average discount rate used to determine the present value of the Company’s operating leases’ future payments was approximately 6%6.0%.


2.3.REVENUE FROM CONTRACTS WITH CUSTOMERS
Performance Obligations Satisfied Over Time—Revenue for the heavy civil construction segment contracts that satisfy the criteria for over time recognition is recognized as the work progresses. The majority of the revenue is derived from long-term, heavy civil construction contracts and projects that typically span between 12 months to 36 months. Revenue from products and services transferred to customers over time accounted for 81%86% and 84% of revenue for the three and six months ended March 31,June 30, 2019, respectively. Revenue from products and services transferred to customers over time accounted for 83% and 84% of revenue for the three and six months ended June 30, 2018, respectively.
Performance Obligations Satisfied at a Point in Time—Revenue for the residential construction segment contracts that do not satisfy the criteria for over time recognition is recognized at a point in time and utilizes an output measure for performance based on the completion of a unit of work (e.g., residential foundation). The typical time frame for completion of a residential foundation is less than one month. Revenue from products and services transferred to customers at a point in time accounted for 19%14% and 16% of revenue for the three and six months ended March 31,June 30, 2019, respectively. Revenue from products and services transferred to customers at a point in time accounted for 17% and 16% of revenue for the three and six months ended June 30, 2018, respectively.
Backlog—On March 31,June 30, 2019, the Company had approximately $808,700$909,000 of remaining performance obligations (which is also referred to as “backlog”) in its heavy civil construction segment, which is also referred to as backlog.segment. The Company expects to recognize approximately 78%70% of its backlog as revenue during the next twelve months, and the balance thereafter.
Contract Estimates—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. Changes in estimated revenues and gross margin resulted in a net decreaseincrease of approximately $200$3,500 and $3,300 for the three and six months ended June 30, 2019, respectively, and a net increase of approximately $1,300$300 and $1,700 for the three and six months ended March 31, 2019 andJune 30, 2018, respectively, included in “Operating income” on the Condensed Consolidated Statements of Operations. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined.
Variable Consideration—The transaction price for contracts may include variable consideration, which includes increases to transaction price for approved and unapproved change orders, claims and incentives, and reductions to transaction price for liquidated damages. 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, the Company concluded that it was appropriate to include in project price amounts of approximately $15,700 and $9,300 at both March 31,June 30, 2019 and December 31, 2018, respectively, in project price. These amounts, reflected in “Costs and estimated earnings in excess of billings on uncompleted contracts” on itsthe Condensed Consolidated Balance Sheets, primarily relatingrelate to extended delays on a bridge project in Texas.Texas due to design errors in the original owner provided project plan. However, unapproved change order and claim amounts are subject to negotiations which may cause actual results to differ materially from estimated and recorded amounts.
Revenue by Heavy Civil Construction Category—The Company’s heavy civil construction segment’s portfolio of products and services consists of approximately 150 active contracts. The following series of tables presents the Company’s heavy civil construction revenue disaggregated by several categories:

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 when 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.
Contract Balances—The timing of revenue recognition, billings and cash collections results in billed accounts receivable and costs and estimated earnings in excess of billings on uncompleted contracts (contract assets) on the Condensed Consolidated Balance Sheet. In the Company’s heavy civil construction segment, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., biweekly or monthly) or upon achievement of contractual milestones. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. However, the Company occasionally receives advances or deposits from its customers, before revenue is recognized, resulting in billings in excess of costs and estimated earnings on uncompleted contracts (contract liabilities). These assets and liabilities are reported on the Condensed Consolidated Balance Sheet on a contract-by-contract basis at the end of each reporting period. Changes in the contract asset and liability balances during the threesix month period ended March 31,June 30, 2019, were not materially impacted by any other factors.
The table below reconciles the net excess billings to the amounts included in the Condensed Consolidated Balance Sheets at those dates:

2018
Costs and estimated earnings in excess of billings on uncompleted contracts$44,133

Net amount of billings in excess of costs and estimated earnings on uncompleted contracts$(11,465) $(20,865)
Revenues recognized and billings on uncompleted contracts include cumulative amounts recognized as revenues and billings in prior periods. This revenue primarily represents progress on the Company’s construction jobs.
3.CASH AND CASH EQUIVALENTS
The Company considers all highly liquid investments with original or remaining maturities of three months or less at the time of purchase to be cash equivalents. Cash and cash equivalents includes cash balances held by consolidated 50% owned subsidiaries and the Company’s majority owned construction joint ventures. At March 31, 2019 and December 31, 2018, cash and cash equivalents included approximately $13,300 and $31,000, respectively, attributable to consolidated 50% owned subsidiaries. At March 31, 2019 and December 31, 2018, cash and cash equivalents included approximately $3,100 and $20,500, respectively, attributable to its majority owned construction joint ventures. Majority owned construction joint ventures and consolidated 50% owned subsidiaries cash balances are limited to joint venture activities and are not available for other projects, general cash needs or distribution to the Company without approval of the board of directors, or equivalent body, of the respective joint ventures.
 Restricted cash of approximately $3,900 is included in “Other current assets” on the Condensed Consolidated Balance Sheets at March 31, 2019 and December 31, 2018. This 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.
 The Company holds cash on deposit in U.S. banks, at times, in excess of federally insured limits. Management does not believe that the risk associated with keeping cash deposits in excess of federal deposit insurance limits represents a material risk.


4.CONSOLIDATED 50% OWNED SUBSIDIARIES
The Company has a 50% interest in two subsidiaries (Myers and RHB); both subsidiaries have individual provisions which obligate the Company to purchase each partner’s 50% interests for $20,000 ($40,000 in the aggregate), due to circumstances outlined in the partner agreements that are certain to occur. Therefore, the Company has consolidated these two entities and classified these obligations as mandatorily redeemable and has recorded a liability in “Members’ interest subject to mandatory redemption and undistributed earnings” on the Condensed Consolidated Balance Sheets. In addition, all undistributed earnings at the time of the noncontrolling owners’ death or permanent disability are also mandatorily payable. In the event of either Mr. Buenting’s or Mr. Myers’s death, the Company 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.
The liability consists of the following:

Fifty percent of the earnings of these consolidated 50% owned subsidiaries for the three and six months ended March 31,June 30, 2019 were approximately $1,500 and March 31,$2,700, respectively and for the three and six months ended June 30, 2018 were approximately $1,300,$4,700 and $600,$5,300, respectively. These amounts were included in “Other operating expense, net” on the Company’s Condensed Consolidated Statements of Operations. 
The Company must determine whether any of its entities, including these two 50% owned subsidiaries, in which it participates, is a variable interest entity (“VIE”). The Company determined Myers is a VIE, as Sterling 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.

5.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 its 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 interestFor these joint ventures, 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 StatementCondensed Consolidated Statements of Operations line item “Net income attributable to noncontrolling interests”, respectively.

Oaktree Facility—At March 31,June 30, 2019, the Company had $71,602 outstanding under aan $85,000 term loan with Wilmington Trust, National Association, as agent, and the lenders party thereto (the “Oaktree Facility”). The five-year Oaktree Facility, which matures in April, 2022, is secured by substantially all of the assets of the Company and its subsidiaries.

10.COMMITMENT AND CONTINGENCIES
The Company is required by its insurance providers to obtain and hold a standby letter 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. The Company has cash collateralized the letters of credit, resulting in the cash being designated as restricted.
The Company is the subject of certain other claims and lawsuits occurring in the normal 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.
11.INCOME TAXES AND DEFERRED TAX ASSET/LIABILITY
The Company and its subsidiaries file U.S. federal and various U.S. state income tax returns. Current income tax expense (benefit) represents federal and state taxes based on tax paid or expected to be payable or receivable for the periods shown in the Condensed Consolidated Statements of Operations.
Due to net operating loss carryforwards, the Company does not expect a current federal liability. The Company may incur current state tax liabilities in states in which the Company does not have net operating loss carry forwards. Current income tax expense of $22$86 and $41$108 was recorded for the three and six months ended March 31,June 30, 2019, respectively and for the three and six months ended June 30, 2018 was $97 and $138, respectively.
The Company’s deferred tax expense reflects the change in deferred tax assets and liabilities. The Company performs an analysis at the end of each reporting period to determine whether it is more likely than not the deferred tax assets are expected to be realized in future years. Based upon this analysis, a valuation allowance of approximately $31,700 has been applied to the Company’s net deferred tax assets as of March 31,at both June 30, 2019 and December 31, 2018. As part of this analysis, the Company monitors its quarterly results. Based on the Company’s continued positive income trend and current forecast for the full year of 2019, we believe that there could be enough positive evidence to remove the valuation allowance in the fourth quarter of 2019. Deferred tax liabilities are a consideration in the analysis of whether to apply a valuation allowance because taxable temporary differences may be used as a source of taxable income to support the realization of deferred tax assets. A deferred tax liability that relates to an asset with an indefinite life, such as goodwill, may not be considered a source of income and should not be netted against deferred tax assets for valuation allowance purposes. The Company expects to have a deferred tax liability for the excess of book over tax basis difference in its goodwill. A $141$620 and $761 deferred tax expense for the three and six months ended March 31,June 30, 2019, respectively has been recorded to reflect this liability.
The effective income tax rate varied from the statutory rate primarily as a result of the change in the valuation allowance, net income attributable to noncontrolling interest owners which is taxable to those owners rather than to the Company, state income taxes and other permanent differences. For interim periods, the Company estimates an annual effective tax rate and applies that rate to year-to-date operating results.
As a result of the Company’s analysis, management has determined that the Company does not have any material uncertain tax positions.

OVERVIEW

General—Sterling Construction Company, Inc. (“Sterling” or “the Company”), is a construction company that specializes in heavy civil infrastructure construction and infrastructure rehabilitation as well as residential construction projects. The Company operates primarily in Arizona, California, Colorado, Hawaii, Nevada, Texas and Utah, as well as other states in which there are feasible construction opportunities. 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. Residential construction projects include concrete foundations for single-family homes.
 
MARKET OUTLOOK AND TRENDS
Heavy Civil Construction—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, Sterling is in year four of the 2015 federally funded five-year $305 billion 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 next year, the federal government is currently working towards a bipartisan Federal Infrastructure Bill that would further stabilize the Highway Trust Fund. Should the federal government approve this incremental infrastructure investment in 2019, it would be an additional growth catalyst; however, it would be unlikely to create significant business impact before 2020 or 2021.
Bid Discipline and Project Execution—To ensure that the Company takes full advantage of the improved market conditions and maximizes profitability, the Company has completed an extensive evaluation of its historical success on heavy civil construction projects based on project size, end customer, product delivered and geography. The knowledge gained has now been incorporated into a more formal and rigorous bid evaluation and approval process which, along with the institution of common processes, will enable the Company to focus its resources on the most beneficial projects and significantly reduce its risk.
Backlog—At March 31,June 30, 2019, backlog of construction projects, which is made up solely of the heavy civil construction segment, was $808.7$909.0 million, as compared to $850.7 million at December 31, 2018. The contracts in this backlog are typically completed in 12 to 36 months. Contracts for which the Company is the apparent low bidder on the project (“Unsigned Low-bid Awards”) are excluded from backlog until the contract has been executed by its customer. Unsigned Low-bid Awards were $401.5$314.9 million at March 31,June 30, 2019 as compared to $292.7 million at December 31, 2018. The combination of backlog and Unsigned Low-bid Awards, which the Company refers to as “Combined Backlog,” totaled $1.2 billion and $1.1 billion, respectively at March 31,June 30, 2019 and December 31, 2018. Backlog includes $40.1$34.3 million and $33.6 million at March 31,June 30, 2019 and December 31, 2018, respectively, attributable to the Company’s share of estimated revenues related to joint ventures where the Company is a noncontrolling joint venture partner.
The Company’s margin in backlog has decreased approximately 13 basis points,increased from 8.5% at December 31, 2018 to 8.3%8.8% at March 31, 2019. The decrease is driven by adverse weather conditionsJune 30, 2019 and mix. The Company’s margin inthe Combined Backlog decreased to 8.6% at March 31, 2019margin increased from 8.9% at December 31, 2018 to 9.1% at June 30, 2019, driven by a greater mix of heavy highway awards.
Residential Construction—Continuing revenue growth of the Company’s residential construction business is directly related to the growth of 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’s customers’ expected average growth during 2019 is approximately 10% in the Dallas-Fort Worth Metroplex.Metroplex, however some of this growth may have been dampened by significant Texas weather impacts during the year. The Company has continued its expansion of the residential business into the Houston market and surrounding areas.

Revenues—Revenues increased $1.5decreased $4.6 million, or 0.7% in2% for the firstsecond quarter of 2019 compared with the firstsecond quarter of 2018. The increasedecrease in the firstsecond quarter of 2019 was driven by a $7.5$9.5 million decrease in residential construction and by a $4.8 million increase in residential construction, partially offsetheavy civil construction. Revenues decreased $3.2 million, or 1% in the six months ended June 30, 2019 compared with the six months ended June 30, 2018. The decrease in the six months ended June 30, 2019 was driven by a $6.1$1.2 million decrease in heavy civil construction and a $2.0 million decrease in residential construction. Both of our operating segments were negatively impacted by unusually severe weather in the first half of 2019.
Gross profit—Gross profit decreased $0.3$5.6 million for the firstsecond quarter of 2019 compared with the firstsecond quarter of 2018. The Company’s gross margin as a percent of revenue decreased to 8.7%9.7% in the firstsecond quarter of 2019, as compared to 8.9%11.6% in the firstsecond quarter of 2018. The decrease in gross margin during the firstsecond quarter of 2019 as compared to the firstsecond quarter of 2018 was driven by lower revenues from our higher margin residential construction segment and a lower margin mix of heavy civil construction projects. Gross profit decreased $5.9 million for the six months ended June 30, 2019 compared with the six months ended June 30, 2018. The Company’s gross margin as a percent of revenue decreased to 9.2% in the six months ended June 30, 2019, as compared to 10.4% in the six months ended June 30, 2018. The decrease in gross margin during the six months ended June 30, 2019 as compared to the six months ended June 30, 2018 was driven by a decrease in heavy civil construction.construction and residential construction’s lower volume from revenues.
At March 31,June 30, 2019 and 2018, the Company had approximately 141134 and 178184 heavy civil contracts-in-progress, respectively, which were less than 90% complete. 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 the Company is able to refine its estimate of total revenues (including incentives, delay penalties, change orders and claims), 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 increased $0.2decreased $2.4 million to $12.5$10.8 million during the firstsecond quarter of 2019 from $12.3$13.2 million in the firstsecond quarter of 2018. As a percent of revenues, general and administrative expenses increased 0.5%decreased approximately 90 basis points to 5.6%4.1% during the three months ended March 31,June 30, 2019. General and administrative expenses decreased $2.2 million to $23.3 million during the six months ended June 30, 2019 from $25.5 million during the six months ended June 30, 2018, primarily due to higher business development costs in 2018. As a percent of revenues, general and administrative expenses decreased approximately 40 basis points to 4.8% during the six months ended June 30, 2019.


Other operating expense, net—Other operating expense, net, includes 50% of earnings and losses related to Members’ interestsinterest of consolidated 50% owned subsidiaries, earn-out expense, and other miscellaneous operating income or expense. Members’ interest earnings are treated as an expense and increase itsthe liability account. The change in other operating expense, net, was $1.5$2.2 million during the firstsecond quarter. Earn-out expense decreased by $0.5 million during the second quarter of 2019 to $0.5 million from $1.0 million in the second quarter of 2018, driven by the lower income generated by residential construction. Members’ interest earnings decreased by $1.9 million during the second quarter of 2019 to $2.8 million from $4.7 million in the second quarter of 2018, reflecting decreased revenue and project mix.
The change in other operating expense, net, was $0.7 million during the six months ended June 30, 2019. Earn-out expense increased by $0.8$0.3 million during the six months ended June 30, 2019 to $1.5 million from $1.2 million in the six months ended June 30, 2018, driven by an increase in the first quarter of 2019, partly offset by the aforementioned second quarter 2019 decrease. Members’ interest earnings decreased by $1.2 million during the six months ended June 30, 2019 to $1.0$4.1 million from $0.2$5.3 million in the first quarter of 2018. Members’ interest earnings increased by $0.7 million during the first quarter of 2019 to $1.3 million from $0.6 million in the first quarter of 2018.six months ended June 30, 2018, reflecting decreased revenue and project mix.
Interest expense—Interest expense was $3.1$2.9 million in the firstsecond quarter of 2019 compared to $3.1 million in the firstsix months ended June 30, 2018 and interest expense was $6.0 million in the six months ended June 30, 2019 compared to $6.2 million in the second quarter of 2018. The interest expense on lower comparative debt levels was partially offset by higher interest rates. The interest expense is primarily related to borrowings under the Oaktree Facility.

Heavy Civil Construction
Revenues—Revenues were $181.2$228.1 million for the firstsecond quarter of 2019, an increase of $4.8 million or 2.2% compared to the second quarter of 2018. The increase was driven by higher revenues of $26.7 million related to fully controlled heavy highway work and increased aviation work. These increases were largely offset by lower revenue of $21.9 million related to two large construction joint venture projects that were substantially complete by the end of 2018. The lower construction joint venture revenues totaled $1.5 million for the second quarter compared to $23.4 million in the second quarter of 2018.
Revenues were $409.3 million for the six months ended June 30, 2019, a decrease of $6.1$1.2 million or 3.2%0.3% compared to the first quarter ofsix months ended June 30, 2018. The decrease was driven by lower revenue of $29.7$51.6 million related to two large construction joint venture projects that were substantially complete by the end of 2018. This decline was partially offset by increased revenues of $23.6$50.4 million related to fully controlled heavy highway work and increased aviation and commercial work. The lower construction joint venture revenues totaled $1.3$2.8 million for the first quartersix months ended June 30, 2019 compared to $31.0$54.4 million in the first quarter ofsix months ended June 30, 2018.
Operating income—Operating lossincome was $0.8$6.1 million for the firstsecond quarter of 2019, a decrease of $2.8$0.3 million, compared to the $1.9$6.4 million in the second quarter of 2018 and operating income was $5.3 million for the six months ended June 30, 2019, a decrease of $3.0 million, compared to the $8.3 million of income in the first quarter ofsix months ended June 30, 2018. The decrease was the result of volume driven decreases from heavy highway work as well as negative weather impacts across our regions in the firstsecond quarter of 2019 and the six months ended June 30, 2019.


Residential Construction
Revenues—Revenues were $42.8$36.0 million for the firstsecond quarter of 2019, an increasea decrease of $7.5$9.5 million or 21.3%20.9%, compared to the firstsecond quarter of 2018. The increasedecrease in revenue was due to severe Texas weather conditions which delayed slab starts with approximately 30 unworkable days during the quarter. These adverse weather conditions decreased completed slabs approximately 22.5% in the second quarter of 2019 as compared to the second quarter of 2018.
Revenues were $78.7 million for the six months ended June 30, 2019, a decrease of $2.0 million or 2.5%, compared to the six months ended June 30, 2018. The decrease in revenue is due to the aforementioned second quarter weather impact, partially offset by completion of fourth quarter weather delayed slab starts that pushed into the first quarter of 2019 and underlying growth in the Dallas-Fort Worth and Houston areas. Completed slabs increased approximately 25%areas in the first quarter of 2019. Completed slabs decreased approximately 1.8% in the six months ended June 30, 2019 as compared to the first quarter ofsix months ended June 30, 2018.
Operating income—Operating income was $5.6$5.0 million for the firstsecond quarter of 2019, an increasea decrease of $0.8$0.7 million, compared to the firstsecond quarter of 2018. The increasedecrease was driven by additionallower volume from revenues as described above, partially offset by increased earnout expense.above. Operating income was $10.6 million for the six months ended June 30, 2019, an increase of $0.1 million, compared to the six months ended June 30, 2018.

Operating Activities—During the threesix months ended March 31,June 30, 2019, net cash used in operating activities was $19.2$4.3 million compared to $22.5$7.9 million in the threesix months ended March 31,June 30, 2018. Cash flows used in operating activities were driven by changes in accounts receivable, inventory, net contracts in progress and accounts payable balances (collectively, “Contract Capital”), as discussed below, partly offset by non-cash items in operating activities. Non-cash items in operating activities include depreciation and amortization expense, which was $4.4$8.5 million and $4.1$8.3 million in the threesix months ended March 31,June 30, 2019 and 2018.
Cash and Working Capital—Cash at March 31,June 30, 2019, was $56.8$71.7 million, and includes the following components:

The decrease in total cash is primarily due to the Company’s seasonality of cash outflows in the first half of the year and cash inflows in the back half of the year. We expect our full year cash from operations to approximate operating income. The increase in generally available cash is primarily due to the seasonal ramp in the cash flow cycle, partly offset by the use of cash for operations, $5.6$5.8 million of repayments on long-term debt, $5.1 million of noncontrolling interest distributions, and $3.2 million for stock repurchases during the threesix months ended March 31,June 30, 2019. The decrease in consolidated 50% owned subsidiaries and construction joint venture cash levels were driven by seasonality, prompting lower volumes in the first quarter of 2019 coupled with the substantial completion of two large construction joint venture projects. The Company’s working capital decreased $16.5$12.9 million to $106.9$110.5 million at March 31,June 30, 2019 from $123.4 million at December 31, 2018, primarily due to seasonality, the cash factors previously described, and the Contract Capital discussion below.


Contract Capital—The need for working capital for the Company’s business varies due to fluctuations in operating activities and investments in its Contract Capital. The changes in the components of Contract Capital were as follows:

The threesix months ended March 31,June 30, 2019 change in Contract Capital reduced liquidity by $29.4$28.8 million. Fluctuations in the Contract Capital balance and its components are not unusual and are impacted by the size of projects and changing type and mix of projects in Backlog. The Company’s Contract Capital is particularly impacted by seasonality, the timing of new awards, and related payments of performing work 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. The Company expects cash flow from operations to improve, principally driven by seasonality.
Investing Activities—During the threesix months ended March 31,June 30, 2019, net cash used in investing activities was $3.7$4.1 million compared to $1.0$4.0 million in the threesix months ended March 31,June 30, 2018. The use of cash was driven by purchases of capital equipment. Capital equipment is acquired as needed to support changing levels of production activities and to replace retiring equipment. Expenditures for the replacement of certain equipment and to expand construction fleet were approximately $3.8$4.9 million for the threesix months ended March 31,June 30, 2019 and $1.9$5.3 million for the threesix months ended March 31,June 30, 2018.
Financing Activities—During the threesix months ended March 31,June 30, 2019, net cash used in financing activities was $14.4$14.0 million compared to $5.0$5.5 million in the threesix months ended March 31,June 30, 2018. The use of cash was driven by $5.6$5.8 million of repayments on long-term debt (primarily consisting of $3.0 million of repayments on the Oaktree Facility and $2.4 million of deferred cash payments for the Tealstone Acquisition), $5.1 million of distributions to the Company’s noncontrolling interest partners, and $3.2 million for the purchase of treasury stock.
Credit Facility and Other Sources of Capital—In addition to the Company’s available cash, cash equivalents and cash provided by operations, from time to time, the Company uses borrowings to finance acquisitions, capital expenditures and working capital needs.


Borrowings—Average borrowings under the Oaktree Facility for the threesix months ended March 31,June 30, 2019 was $73.9$72.8 million and for the threesix months ended March 31,June 30, 2018 was $83.1$81.6 million. Based on the Company’s average borrowings and its 2019 forecasted cash needs, the Company continues to believe that it has sufficient liquid financial resources to fund its requirements for the next twelve months of operations, including its bonding requirements.
Capital Strategy—The Company will continue to explore additional revenue growth and capital alternatives to strengthen its financial position in order to take advantage of the improving heavy civil infrastructure market. 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, managing its debt balances, and investing in adjacent markets or other opportunities.
INFLATION
Inflation generally has not had a material impact on the Company’s financial results; however, from time to time, increases in oil, fuel and steel prices have affected its cost of operations. Anticipated cost increases and reductions are considered in the Company’s bids to customers on proposed new construction projects.


When the Company is the successful bidder on a heavy civil construction project, the Company executes purchase orders with material suppliers and contracts with subcontractors covering the prices of most materials and services, other than oil and fuel products, thereby mitigating future price increases and supply disruptions. These purchase orders and contracts do not contain quantity guarantees and the Company has no obligation for materials and services beyond those required to complete the contracts with its customers. There can be no assurance that increases in prices of oil and fuel used in the Company’s business will be adequately covered by the estimated escalation the Company has included in its bids and there can be no assurance that all of its vendors will fulfill their pricing and supply commitments under their purchase orders and contracts with the Company. The Company adjusts the total estimated costs on projects when it is believed it is probable that there will be cost increases which will not be recovered from customers, vendors or re-engineering.
Inflation affects residential construction projects minimally as these projects are typically completed in less than one month.
OFF-BALANCE SHEET ARRANGEMENTS AND JOINT VENTURES
The Company participates in various construction joint ventures in order to share expertise, risk and resources for certain highly complex projects. The venture’s contract with the project owner typically requires joint and several liability among the joint venture partners. Although the Company’s agreements with its joint venture partners provide that each party will assume and fund its share of any losses resulting from a project, if one of its partners is unable to pay its share, the Company would be fully liable for such share under its 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 incurs a loss or additional costs that the Company could incur should the partner fail to provide the services and resources toward project completion to which it committed in the joint venture agreement.
At March 31,June 30, 2019, there was approximately $82.7$71.8 million of construction work to be completed on unconsolidated construction joint venture contracts, of which $40.1$34.3 million represented the Company’s proportionate share. Due to the joint and several liability under the Company’s joint venture arrangements, if one of its joint venture partners fails to perform, the Company and the remaining joint venture partners would be responsible for completion of the outstanding work. As of March 31,June 30, 2019, the Company was not aware of any situation that would require it to fulfill responsibilities of its joint venture partners pursuant to the joint and several liability provisions under its contracts.
CRITICAL ACCOUNTING ESTIMATES
The discussion and analysis of the financial condition and results of operations are based on the Company’s Condensed Consolidated Financial Statements, which have been prepared in accordance with U.S. GAAP. The preparation of these Condensed Consolidated 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 Consolidated Financial Statements.

Revenue Recognition
Performance Obligations Satisfied Over Time—Revenue for the heavy civil construction segment 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 Consolidated Financial Statements and related disclosures.



Goodwill
At June 30, 2019, the Company’s goodwill balance was $85.2 million. 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 an annual impairment assessment during the fourth quarter of each year based on balances as of October 1. During the fourth quarter 2018, the Company performed a qualitative assessment of goodwill, and based on this assessment, no indicators of impairment were present. Additionally, during the six months ended June 30, 2019, the Company noted no indicators of impairment.

Other Intangible Assets
The Company amortizes finite-lived intangible assets on a straight-line basis with lives ranging from 5 to 25 years, absent any indicators of impairment. The Company reviews tangible assets and finite-lived intangible assets for impairment when 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. During the six months ended June 30, 2019, the Company noted no indicators of impairment. See Note 7 to the Financial Statements for further discussion of the Company’s other intangible assets.

Income Taxes
Deferred Tax Realization Assessments—The Company performs an analysis at the end of each reporting period to determine whether it is more likely than not the deferred tax assets are expected to be realized in future years. Based upon this analysis, a valuation allowance of approximately $31.7 million has been applied to the Company’s net deferred tax assets as of June 30, 2019. As part of this analysis, the Company monitors its quarterly results. Based on the Company’s continued positive income trend and current forecast for the full year of 2019, we believe that there could be enough positive evidence to remove the valuation allowance in the fourth quarter of 2019. Deferred tax liabilities are a consideration in the analysis of whether to apply a valuation allowance because taxable temporary differences may be used as a source of taxable income to support the realization of deferred tax assets. A deferred tax liability that relates to an asset with an indefinite life, such as goodwill, may not be considered a source of income and should not be netted against deferred tax assets for valuation allowance purposes. The Company expects to have a deferred tax liability for the excess of book over tax basis difference in its goodwill.

As a result of the Company’s analysis, management has determined that the Company does not have any material uncertain tax positions.

NEW ACCOUNTING STANDARDS
See the applicable section of Note 2 to the Condensed Consolidated Financial Statements for a discussion of new accounting standards.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
Changes in interest rates are one of the Company’s sources of market risk. Interest on outstanding indebtedness under the Oaktree Facility is equal to the one-, two-, three- or six-month London Interbank Offered Rate, or LIBOR, plus 8.75% per annum on the unpaid principal amount of the Loan, subject to adjustment under certain circumstances. The Company’s interest rates for the periods ended March 31,June 30, 2019, December 31, 2018 and March 31,June 30, 2018 were 11.2%11.14%, 11.2%11.18% and 10.4%10.87% respectively. This represents an increase of approximately 802.7 basis points year over year. There are no amortized principal payments; however, the Company is required to prepay the Loan, and in certain cases pay a prepayment premium thereon, with proceeds received from the issuances of debt or equity, transfers, events of loss and extraordinary receipts. The Company is required to make an offer quarterly to the lenders to prepay the Loan in an amount equal to 75% of its excess cash flow, plus accrued and unpaid interest thereon and a prepayment premium. At March 31,June 30, 2019, the Company had a term loan of $71.6 million outstanding under this facility. A 1% increase in the interest rate would increase interest expense by $0.7 million per year.
See “Inflation” above regarding risks associated with materials and fuel purchases required to complete construction contracts.

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, as amended (the “Exchange Act”), 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 Exchange Act). 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 March 31,June 30, 2019 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 March 31,June 30, 2019 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 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, provide 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 2018 Form 10-K. You should carefully consider such risk factors, which could materially affect the business, financial condition or future results.

On November 2, 2018, the Board of Directors approved a plan that authorized stock repurchases of up to 2.0 million shares of the Company’s common stock. Under the plan, the Company may repurchase its common stock in the open market or through privately negotiated transactions at such times and at such prices as determined to be in the Company’s best interest. The amount and timing of any purchases will depend on a number of factors, including the Company’s liquidity position and trading price, trading volume and general market conditions. No assurance can be given that any particular amount of common stock will be repurchased. This repurchase program expires on June 30, 2020 and may be modified, extended or terminated by the Board at any time. The table below sets forth the Company’s share repurchase during the last fiscal quarter.
