we continuously evaluate the marketplace for strategic acquisition opportunities . a fundamental component of our profitable growth strategy is to pursue acquisitions that will expand our platform in key u.s. markets . where the impact of acquisitions is noted in discussing results , it refers to acquisitions effected within the last twelve months of the end of the relevant period . fiscal year 2016 acquisition on november 30 , 2015 , we acquired the professional services business ( `` pipeline services `` ) of willbros group ( `` willbros `` ) in an all cash transaction . the $ 124.5 million purchase price consisted of ( i ) an initial cash payment of $ 120.0 million paid at closing , and , ( ii ) a second cash payment due of $ 7.5 million payable at the earlier of certain willbros contract novations ( or written approval of a subcontract ) and willbros obtaining certain consents , or march 15 , 2016 , net of a preliminary estimate working capital adjustment due from willbros . the second cash payment was made in two tranches , with $ 2.4 million paid in march 2016 and the remaining balance paid in july 2016 in conjunction with the final net working capital settlement . goodwill of $ 60.3 million was initially recorded prior to impairment , all of which is expected to be tax deductible , and other intangible assets of $ 44.5 million were recorded as a result of this acquisition . the goodwill recognized is attributable to the future strategic growth opportunities arising from the acquisition , pipeline service 's highly skilled assembled workforce , which does not qualify for separate recognition , and the expected cost synergies of the combined operations . the pipeline services operating segment has contributed $ 60.7 million in gross revenue , $ 48.4 million in net service revenue , and an operating loss of $ ( 7.5 ) million to our results for the period from november 30 , 2015 through june 30 , 2016 . fiscal year 2015 acquisition on september 29 , 2014 , we acquired all of the outstanding stock of nova training inc. and all of the outstanding membership interests of nova earthworks , llc ( collectively `` nova `` ) based in midland , texas . nova provides safety training and environmental services as well as oil spill response , remediation and general oil field construction services to customers in the oil and gas industry . the initial purchase price consisted of ( i ) a cash payment of $ 7.2 million payable at closing , ( ii ) a second cash payment of $ 2.6 million placed into escrow , of which $ 0.5 million was paid in six months and the remaining $ 2.1 million was paid in 18 months , ( iii ) 50 thousand shares of our common stock valued at $ 0.3 million on the closing date , and ( iv ) a $ 0.6 million net working capital adjustment . the sellers are also entitled to up to $ 1.5 million in contingent cash consideration through an earn-out provision based on the nsr performance of the acquired firm over the 24 month period following closing . we estimated the fair value of the remaining contingent earn-out liability to be $ 0.3 million based on the projections and probabilities of reaching the performance goals through september 2016. goodwill of $ 3.7 million , none of which is expected to be tax deductible , and other intangible assets of $ 3.6 million were recorded as a result of this acquisition . the goodwill is primarily attributable to the synergies and ancillary growth opportunities expected to arise after the acquisition . the fair values of assets and liabilities of the nova acquisition have been recorded in the environmental operating segment . the impact of this acquisition was not material to our condensed consolidated balance sheets and results of operations . 22 fiscal year 2014 acquisitions on january 2 , 2014 , we acquired all of the outstanding stock of emcor energy services , inc. ( `` ees `` ) , a subsidiary of emcor group , inc. , headquartered in san francisco , california . ees provides engineering and related consulting services to utilities to support their energy programs in california . services include engineering , technical review , verification , and administration of utilities ' energy efficiency programs . the purchase price of $ 1.6 million consisted of a cash payment of $ 1.4 million , and a $ 0.2 million net working capital adjustment . goodwill of $ 0.2 million , none of which is expected to be tax deductible , and other intangible assets of $ 0.9 million were recorded as a result of this acquisition . the ees acquisition has been recorded in the energy operating segment . the impact of this acquisition was not material to our consolidated balance sheets and results of operations . on july 22 , 2013 , we acquired all of the outstanding stock of utility support systems , inc.

: ( i ) cash of $ 2.5 million payable at closing , ( ii ) a second cash payment of $ 1.8 million payable on the one-year anniversary of the closing date subject to withholding for various contractual issues , and ( iii ) 34 thousand shares of our common stock valued at $ 0.3 million on the closing date . the selling shareholders were also entitled to contingent cash consideration through an earn-out provision based on nsr performance of the acquired firm over the twelve month period following closing . story_separator_special_tag claims are amounts in excess of the agreed contract price that we seek to collect from our clients or others for 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 . costs related to change orders and claims are recognized when they are incurred . change orders are included in total estimated contract revenue when it is probable that the change order will result in a bona fide addition to contract value and can be reliably estimated . claims are included in total estimated contract revenues only to the extent that contract costs related to the claims have been incurred and when it is probable that the claim will result in a bona fide addition to contract value which can be reliably estimated . no profit is recognized on claims until final settlement occurs . for the fiscal years ended june 30 , 2016 , 2015 and 2014 , we did not recognize any revenue related to claims . other contract matters federal acquisition regulations ( `` far `` ) , which are applicable to our federal government contracts and may be incorporated in many local and state agency contracts , limit the recovery of certain specified indirect costs on contracts . cost-plus contracts covered by far or with certain state and local agencies also require an audit of actual costs and provide for upward or downward adjustments if actual recoverable costs differ from billed recoverable costs . most of our federal government contracts are subject to termination at the discretion of the client . contracts typically provide for reimbursement of costs incurred and payment of fees earned through the date of such termination . contracts with the federal government are subject to audit , primarily by the defense contract audit agency ( `` dcaa `` ) , which reviews our overhead rates , operating systems and cost proposals . during the course of its audits , the dcaa may disallow costs if it determines that we have accounted for such costs in a manner inconsistent with cost accounting standards or far . our last incurred cost audit was for fiscal year 2004 and resulted in an immaterial adjustment . dcaa determined that an audit of incurred 26 cost proposals submitted to dcaa for fiscal years 2005 through 2013 was not required . historically , we have not had any material cost disallowances by the dcaa as a result of audit , however there can be no assurance that dcaa audits will not result in material cost disallowances in the future . allowance for doubtful accounts —an allowance for doubtful accounts is maintained for estimated losses resulting from the failure of our clients to make required payments . the allowance for doubtful accounts has been determined through reviews of specific amounts deemed to be uncollectible and estimated write-offs as a result of clients who have filed for bankruptcy protection plus an allowance for other amounts for which some loss is determined to be probable based on current circumstances . if the financial condition of clients or our assessment as to collectability were to change , adjustments to the allowances may be required . income taxes —we are required to estimate the provision for income taxes , including the current tax expense together with assessing temporary differences resulting from differing treatments of assets and liabilities for tax and financial accounting purposes . these differences between the financial statement and tax bases of assets and liabilities , together with net operating loss ( `` nol `` ) carryforwards and tax credits are recorded as deferred tax assets or liabilities on the consolidated balance sheets . an assessment is required to be made of the likelihood that the deferred tax assets will be recovered from future taxable income . to the extent that we determine that it is more likely than not that the deferred asset will not be utilized , a valuation allowance is established . taxable income in future periods significantly above or below that projected will cause adjustments to the valuation allowance that could materially decrease or increase future income tax expense . we recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position . the tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50 % likelihood of being realized upon ultimate settlement . accounting literature also provides guidance on derecognition of income tax assets and liabilities , classification of current and deferred income tax assets and liabilities , accounting for interest and penalties associated with tax positions , and income tax disclosures . judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns . variations in the actual outcome of these future tax consequences could materially impact our financial statements . acquisitions —we account for acquisitions using the acquisition method of accounting , which requires that assets acquired and liabilities assumed be recognized at fair value as of the acquisition date . the purchase price of acquisitions is allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on estimated fair values , and any excess purchase price over the identifiable assets acquired and liabilities assumed is recorded as goodwill . goodwill typically represents the value paid for the assembled workforce and enhancement of our service offerings . we may use independent valuation specialists to assist in determining the estimated fair values of assets acquired and liabilities assumed , which could require certain significant management assumptions and estimates . transaction costs associated with acquisitions are expensed as they are incurred . goodwill and other intangible assets —in accordance with
