the company is under no obligation ( and expressly disclaims any such obligation ) to update or revise any forward-looking statement that may be made from time to time , whether as a result of new information , future developments or otherwise . please review `` part i , item 1arisk factors `` in this annual report for a discussion of the factors , risks and uncertainties that could affect our future results . our fiscal year consists of 52 or 53 weeks , ending on the friday closest to september 30. for clarity of presentation , we present all periods as if the year ended on september 30. we refer to the fiscal year ended september 30 , 2016 as `` fiscal 2016 `` and the fiscal year ended september 30 , 2017 as `` fiscal 2017 . `` 36 overview we are a leading fully integrated firm positioned to design , build , finance and operate infrastructure assets for governments , businesses and organizations in more than 150 countries . we provide planning , consulting , architectural and engineering design services to commercial and government clients worldwide in major end markets such as transportation , facilities , environmental , energy , water and government markets . we also provide construction services , including building construction and energy , infrastructure and industrial construction . in addition , we provide program and facilities management and maintenance , training , logistics , consulting , technical assistance , and systems integration and information technology services , primarily for agencies of the u.s. government and also for national governments around the world . our business focuses primarily on providing fee-based planning , consulting , architectural and engineering design services and , therefore , our business is labor intensive . we primarily derive income from our ability to generate revenue and collect cash from our clients through the billing of our employees ' time spent on client projects and our ability to manage our costs . aecom capital primarily derives its income from real estate development sales . we report our business through four segments : design and consulting services ( dcs ) , construction services ( cs ) , management services ( ms ) , and aecom capital ( acap ) . such segments are organized by the types of services provided , the differing specialized needs of the respective clients , and how we manage the business . we have aggregated various operating segments into our reportable segments based on their similar characteristics , including similar long-term financial performance , the nature of services provided , internal processes for delivering those services , and types of customers . our dcs segment delivers planning , consulting , architectural and engineering design services to commercial and government clients worldwide in major end markets such as transportation , facilities , environmental , energy , water and government . dcs revenue is primarily derived from fees from services that we provide , as opposed to pass-through costs from subcontractors . our cs segment provides construction services , including building construction and energy , infrastructure and industrial construction , primarily in the americas . cs revenue typically includes a significant amount of pass-through costs from subcontractors . our ms segment provides program and facilities management and maintenance , training , logistics , consulting , technical assistance , and systems integration and information technology services , primarily for agencies of the u.s. government and also for national governments around the world . ms revenue typically includes a significant amount of pass-through costs from subcontractors . our acap segment invests in real estate , public-private partnership ( p3 ) and infrastructure projects . acap typically partners with investors and experienced developers in the united states and europe as co-general partners . in addition , acap may , but is not required to , enter into contracts with our other aecom affiliates to provide design , engineering , construction management , development and operations and maintenance services for acap funded projects . in april 2017 , acap completed a transaction to sell its 50 % equity interest in provost square i llc , an unconsolidated joint venture which invested in a real estate development in new jersey , for $ 133 million , which resulted in net cash proceeds of $ 77 million and a gain of $ 52 million in our fiscal year 2017. accordingly , we begain reporting acap as a separate segment beginning in the third quarter of fiscal 2017. results of operations for acap were not material in prior periods . during the first quarter of fiscal year 2017 , an operation and maintenance related entity previously reported within our cs segment was realigned within our ms segment to reflect present management oversight . accordingly , approximately $ 130 million and $ 137 million of revenue and $ 124 million and 37 $ 130 million of cost of revenue for the years ended september 30 , 2016 and 2015 , respectively , were reclassified to conform to the current period presentation . our revenue is dependent on our ability to attract and retain qualified and productive employees , identify business opportunities , integrate and maximize the value of our recent acquisitions , allocate our labor resources to profitable and high growth markets , secure new contracts and renew existing client agreements . demand for our services is cyclical and may be vulnerable to sudden economic downturns and reductions in government and private industry spending , which may result in clients delaying , curtailing or canceling proposed and existing projects . moreover , as a professional services company , maintaining the high quality of the work generated by our employees is integral to our revenue generation and profitability . our costs consist primarily of the compensation we pay to our employees , including salaries , fringe benefits , the costs of hiring subcontractors , other project-related expenses and sales , general and administrative costs . story_separator_special_tag the impairment evaluation process includes , among other things , making assumptions about variables such as revenue growth rates , profitability , discount rates , and industry market multiples , which are subject to a high degree of judgment . material assumptions used in the impairment analysis included the weighted average cost of capital ( wacc ) percent and terminal growth rates . for example , as of september 30 , 2017 , a 1 % increase in the wacc rate represents a $ 800 million decrease to the fair value of our reporting units . as of september 30 , 2017 , a 1 % decrease in the terminal growth rate represents a $ 400 million decrease to the fair value of our reporting units . pension benefit obligations a number of assumptions are necessary to determine our pension liabilities and net periodic costs . these liabilities and net periodic costs are sensitive to changes in those assumptions . the assumptions include discount rates , long-term rates of return on plan assets and inflation levels limited to the united kingdom and are generally determined based on the current economic environment in each host country at the end of each respective annual reporting period . we evaluate the funded status of each of our retirement plans using these current assumptions and determine the appropriate funding level considering applicable regulatory requirements , tax deductibility , reporting considerations and other factors . based upon current assumptions , we expect to contribute $ 26.8 million to our international plans in fiscal 2018. our required minimum contributions for our u.s. qualified plans are not significant . in addition , we may make additional discretionary contributions . we currently expect to contribute $ 12.7 million to our u.s. plans ( including benefit payments to nonqualified plans and postretirement medical plans ) in fiscal 2018. if the discount rate was reduced by 25 basis points , plan liabilities would increase by approximately $ 82.2 million . if the discount rate and return on plan assets were reduced by 25 basis points , plan expense would decrease by approximately $ 0.1 million and increase by approximately $ 3.4 million , respectively . if inflation increased by 25 basis points , plan liabilities in the united kingdom would increase by approximately $ 42.7 million and plan expense would increase by approximately $ 2.7 million . 43 at each measurement date , all assumptions are reviewed and adjusted as appropriate . with respect to establishing the return on assets assumption , we consider the long term capital market expectations for each asset class held as an investment by the various pension plans . in addition to expected returns for each asset class , we take into account standard deviation of returns and correlation between asset classes . this is necessary in order to generate a distribution of possible returns which reflects diversification of assets . based on this information , a distribution of possible returns is generated based on the plan 's target asset allocation . capital market expectations for determining the long term rate of return on assets are based on forward-looking assumptions which reflect a 20-year view of the capital markets . in establishing those capital market assumptions and expectations , we rely on the assistance of our actuaries and our investment consultants . we and the plan trustees review whether changes to the various plans ' target asset allocations are appropriate . a change in the plans ' target asset allocations would likely result in a change in the expected return on asset assumptions . in assessing a plan 's asset allocation strategy , we and the plan trustees consider factors such as the structure of the plan 's liabilities , the plan 's funded status , and the impact of the asset allocation to the volatility of the plan 's funded status , so that the overall risk level resulting from our defined benefit plans is appropriate within our risk management strategy . between september 30 , 2016 and september 30 , 2017 , the aggregate worldwide pension deficit decreased from $ 696.1 million to $ 553.0 million due to rising global asset prices . although funding rules are subject to local laws and regulations and vary by location , we expect to reduce this deficit over a period of 7 to 10 years . if the various plans do not experience future investment gains to reduce this shortfall , the deficit will be reduced by additional contributions . accrued professional liability costs we carry professional liability insurance policies or self-insure for our initial layer of professional liability claims under our professional liability insurance policies and for a deductible for each claim even after exceeding the self-insured retention . we accrue for our portion of the estimated ultimate liability for the estimated potential incurred losses . we establish our estimate of loss for each potential claim in consultation with legal counsel handling the specific matters and based on historic trends taking into account recent events . we also use an outside actuarial firm to assist us in estimating our future claims exposure . it is possible that our estimate of loss may be revised based on the actual or revised estimate of liability of the claims . foreign currency translation our functional currency is the u.s. dollar . results of operations for foreign entities are translated to u.s. dollars using the average exchange rates during the period . assets and liabilities for foreign entities are translated using the exchange rates in effect as of the date of the balance sheet . resulting translation adjustments are recorded as a foreign currency translation adjustment into other accumulated comprehensive income/ ( loss ) in stockholders ' equity . we limit exposure to foreign currency fluctuations in most of our contracts through provisions that require client payments in currencies corresponding to the currency in which costs are incurred . as a result of this natural hedge , we generally

cash flows our principal sources of liquidity are cash flows from operations , borrowings under our credit facilities , and access to financial markets . our principal uses of cash are operating expenses , capital expenditures , working capital requirements , acquisitions , and repayment of debt . we believe our anticipated sources of liquidity including operating cash flows , existing cash and cash equivalents , borrowing capacity under our revolving credit facility and our ability to issue debt or equity , if required , will be sufficient to meet our projected cash requirements for at least the next 12 months . generally , we do not provide for u.s. taxes or foreign withholding taxes on gross book-tax basis differences in our non-u.s. subsidiaries because such basis differences are able to and intended to be reinvested indefinitely . determination of the amount of any unrecognized deferred income tax liability on this temporary difference is not practicable because of the complexities of the hypothetical calculation . we have a deferred tax liability in the amount of $ 77.0 million at september 30 , 2017 relating to certain foreign subsidiaries for which the basis difference is not intended to be reinvested indefinitely as part of the liabilities assumed in connection with the acquisition of urs . based on the available sources of cash flows discussed above , we anticipate we will continue to have the ability to permanently reinvest these remaining amounts . at september 30 , 2017 , cash and cash equivalents were $ 802.4 million , an increase of $ 110.3 million , or 15.9 % , from $ 692.1 million at september 30 , 2016. the increase in cash and cash equivalents was primarily attributable to cash provided by operating activities , partially offset by net repayments under our debt agreements , payments for business acquisitions and capital expenditures , net distributions to noncontrolling interest , and investment in unconsolidated joint ventures .
