the company recognizes revenue equal to costs incurred on unapproved change orders when realization of price approval is 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 . 25 the company considers claims to be amounts in excess of agreed 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 support these requirements , the existence of the following items must be satisfied : 1. 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 ; 2. 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 ; 3. costs associated with the claim are identifiable or otherwise determinable and are reasonable in view of the work performed ; and 4. the evidence supporting the claim is objective and verifiable , not based on management 's subjective evaluation of the situation or on unsupported representations . revenues in excess of contract costs incurred on claims are 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 . 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 . the accuracy of our revenue and profit recognition in a given period is dependent on the accuracy of our estimates of the revenues and costs to finish uncompleted contracts . our estimates for all of our significant contracts use a highly detailed “ bottom up ” approach . however , our projects can be highly complex , and in almost every case , the profit margin estimates for a contract will either increase or decrease to some extent from the amount that was originally estimated at the time of bid . because we have a large number of projects of varying levels of size and complexity in process at any given time , these changes in estimates can sometimes offset each other without materially impacting our overall profitability . however , large changes in revenue or cost estimates can have a significant effect on profitability . there are a number of factors that can contribute to changes in estimates of contract cost and profitability . the most significant of these include the completeness and accuracy of the original bid , recognition of costs associated with scope changes , extended overhead due to customer-related and weather-related delays , subcontractor and supplier performance issues , site conditions that differ from those assumed in the original bid ( to the extent contract remedies are unavailable ) , the availability and skill level of workers in the geographic location of the project and changes in the availability and proximity of materials . the foregoing factors , as well as the stage of completion of contracts in process and the mix of contracts at different margins , may cause fluctuations in gross profit between periods , and these fluctuations may be significant . results for 2016 , 2015 and 2014 were adversely affected by certain weather conditions and revisions to estimated profitability on our construction projects . see “ recent developments ― financial results for 2016 , operational issues and outlook for 2017 financial results ” above and “ results of operations ― fiscal year ended december 31 , 2016 compared with fiscal year ended december 31 , 2015 ” for further discussion of the impact on our financial results . contracts receivable , including retainage . contracts receivable are generally based on amounts billed to the customer and currently due in accordance with our contracts . many of the contracts under which the company performs work contain retainage provisions . retainage refers to that portion of billings made by the company but held for payment by the customer pending satisfactory completion of the project . 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 december 31 , 2016 and 2015 , contracts receivable included $ 23.4 million and $ 19.8 million of retainage , respectively , which is being contractually withheld by customers until completion of the contracts . there are certain contracts that are completed in advance of full payment . when the receivable will not be collected within our normal operating cycle , we consider it a long-term contract receivable and it is recorded in “ other assets , net ” in our balance sheet . we consider the credit quality of the borrower to assess the appropriate discount rate to apply and continuously monitor the borrower 's credit quality . at december 2016 and 2015 , there were no such long-term contract receivables recorded in our consolidated balance sheets . story_separator_special_tag the company is proceeding with its contractual rights to recoup additional costs incurred from its customers based upon completing work associated with 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 may 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 with the views of the company 's outside claim consultants , we concluded that including the unapproved change order , claim and entitled unpaid project price amounts of $ 2.2 million , $ 9.2 million and $ 3.9 million , respectively , at december 31 , 2016 , and $ 1.6 million , $ 5.2 million and $ 3.9 million , respectively , at december 31 , 2015 , in “ costs and estimated earnings in excess of billings on uncompleted contracts ” on our consolidated balance sheets was in accordance with gaap . 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 . other operating ( expense ) income , net . other operating ( expense ) income , net , includes 50 % of earnings and losses related to members ' interests , gains and losses from sales of property , plant and equipment , and other miscellaneous operating income or expense . members ' interest earnings are treated as an expense while losses are treated as income as earnings would increase the amount in our liability account “ members ' interest subject to mandatory redemption and undistributed earnings , ” and losses would decrease this liability . other operating expense increased to $ 10.0 million in 2016 from $ 1.5 million in 2015 , with the increase being primarily the result of an increase in members ' interest earnings of approximately $ 8.9 million and $ 1.2 million related to our jbc earn-out expense . general and administrative expenses . general and administrative expenses decreased $ 3.3 million during 2016 to $ 38.6 million from $ 41.9 million in 2015. this decrease is primarily the result of certain non-recurring costs related to consulting services performed and employee severance payments of $ 1.2 million and $ 2.9 million , respectively , recognized in 2015 offset by an increase in certain employee and employee benefit costs in 2016. as a percentage of revenues , general and administrative expenses decreased to 5.6 % in 2016 from 6.7 % in 2015. the decreases in general and administrative expenses , as a percentage of revenue , are primarily the result of the leverage generated from generally fixed costs and increases in revenues . income taxes . our effective income tax rates for 2016 and 2015 were minimal in both periods . in 2016 and 2015 , our effective income tax rate varied from the statutory rate primarily as a result of our deferred tax asset valuation allowance . we expect our tax rate to remain low due to our net operating losses available to offset taxable income . in order to determine that a valuation allowance was necessary , management assessed the available positive and negative evidence to estimate whether sufficient future taxable income would be generated to use the existing deferred tax assets . a significant piece of objective negative evidence evaluated was the cumulative loss incurred over the three-year period ended december 31 , 2016. the cumulative three-year period loss that ended in the fourth quarter of 2016 was the result of the write-downs recorded during the past three years . such objective evidence limits the ability to consider other subjective evidence such as our projections for future growth . on the basis of this evaluation , as of december 31 , 2016 , a full valuation allowance of $ 58.0 million has been recorded on our net deferred tax assets including federal and state net operating loss carryforwards as they are not likely to be realized . the amount of the deferred tax asset considered realizable could be adjusted if objective negative evidence is no longer present and additional weight may be given to subjective evidence such as our projections for growth . 31 net income attributable to noncontrolling interests . the decrease of $ 1.4 million to $ 1.8 million from $ 3.2 million in net income attributable to noncontrolling interest owners for the year ended december 31 , 2016 compared with the same period in 2015 is primarily related to the november 2015 agreement entered with myers . this agreement changed our accounting treatment of our myers 50 % noncontrolling interest , which was included in “ noncontrolling owners ' interests in earnings of subsidiaries and joint ventures , ” to “ other operating ( expense ) income , net ” after the agreement was executed . the myers ' 50 % portion of earnings totaled $ 3.7 million , $ 3.2 million of which was recorded in “ noncontrolling owners ' interest in earnings of subsidiaries and joint ventures ” and $ 0.5 million was recorded in “ other operating expense ( income ) , net . ” during 2016 , the only income attributable to noncontrolling interests was primarily from our utah construction joint venture where our joint venture partner has a 40 % noncontrolling interest . net income attributable to noncontrolling interest from construction joint ventures was $ 1.8 million and an immaterial amount in 2016 and 2015 , respectively . revaluation of noncontrolling interest due to a new agreement .

cash and working capital . cash at december 31 , 2016 , was $ 42.8 million which increased from the prior year based on the items mentioned above . our working capital largely remained flat with a slight decrease of $ 1.0 million to $ 29.3 million from $ 30.6 million at december 31 , 2016 and 2015 , respectively . credit facility and other sources of capital . in addition to our available cash , cash equivalents and cash provided by operations , from time to time , we use borrowings under our available credit or equipment-based credit facilities to finance our capital expenditures and working capital needs . in may 2015 , the company and its wholly-owned subsidiaries entered into a $ 40.0 million loan and security agreement with nations equipment finance , llc ( “ nations ” ) , consisting of a $ 20.0 million term loan and a $ 20.0 million revolving loan ( combined , the “ equipment-based facility ” ) , which replaced the company 's prior credit facility . the sum of the outstanding balances of the equipment-based facility may not exceed the lesser of $ 40.0 million or 65 % of the appraised value of the collateral pledged for the loans . at december 31 , 2016 , the company had a borrowing base of approximately $ 24.4 million , which was the result of calculating 65 % of the appraised value ( where appraised value equals net operating liquidated value ) of the company 's collateral . the amount of the revolving loan that may be borrowed from time to time is the lesser of $ 20.0 million or the available borrowing base . the revolving loan may be utilized to provide ongoing working capital and for other general corporate purposes .
