we applied this change retrospectively to all prior periods presented for which details are presented under the heading “ inventories ” in note a. the cost of specialty fluids inventories that are classified as inventory and assets held for rent is determined using the average cost method . the cost of all other inventories is determined using the fifo method . 25 we periodically review inventory for both potential obsolescence and potential declines in anti cipated selling prices . in this review , we make assumptions about the future demand for and market value of the inventory , and based on these assumptions estimate the amount of any obsolete , unmarketable , slow moving or overvalued inventory . we write down the value of our inventories by an amount equal to the difference between the cost of the inventory and its estimated net realizable value . historically , such write-downs have not been material . if actual market conditions are less favorable than those pro jected by management at the time of the assessment , however , additional inventory write-downs may be required , which could reduce our gross profit and our earnings . intangible assets and goodwill impairment we record tangible and intangible assets acquired and liabilities assumed in business combinations under the acquisition method of accounting . amounts paid for an acquisition are allocated to the assets acquired and liabilities assumed based on their fair values at the date of acquisition . we use assumptions and estimates in determining the fair value of assets acquired and liabilities assumed in a business combination . the determination of the fair value of intangible assets requires the use of significant judgment with regard to assumptions used in the valuation model . we estimate the fair value of identifiable acquisition-related intangible assets principally based on projections of cash flows that will arise from these assets . the projected cash flows are discounted to determine the fair value of the assets at the dates of acquisition . as discussed in note c of our notes to the consolidated financial statements , we acquired tech blend in november 2017 , and the purchase price allocation included separately identifiable intangible assets of $ 29 million . definite-lived intangible assets , which are comprised of trademarks , customer relationships and developed technologies , are amortized over their estimated useful lives and are reviewed for impairment when indication of potential impairment exists , such as a significant reduction in cash flows associated with the assets . we recognized an impairment on intangible assets associated with the purification solutions business in the second fiscal quarter of 2018 , which is discussed in detail below under the heading “ purifications solutions goodwill and long-lived assets impairment charges ” . goodwill is comprised of the purchase price of business acquisitions in excess of the fair value assigned to the net tangible and identifiable intangible assets acquired . goodwill is not amortized , but is reviewed for impairment annually as of may 31 , or when events or changes in the business environment indicate that the carrying value of the reporting unit may exceed its fair value . a reporting unit , for the purpose of the impairment test , is at or below the operating segment level , and constitutes a business for which discrete financial information is available and regularly reviewed by segment management . reinforcement materials , and the fumed metal oxides and specialty compounds businesses within performance chemicals , which are considered separate reporting units , carried our goodwill balances as of may 31 , 2018. the purification solutions reporting unit has no remaining goodwill balance subsequent to the goodwill impairment charge recorded in the second quarter of fiscal 2018. as part of the tech blend acquisition , goodwill of $ 33 million was generated and is reflected in the specialty compounds reporting unit . for the purpose of the goodwill impairment test , we first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount . if an initial qualitative assessment identifies that it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value , an additional quantitative evaluation is performed . alternatively , we may elect to proceed directly to the quantitative goodwill impairment test . if based on the quantitative evaluation the fair value of the reporting unit is less than its carrying amount , a goodwill impairment loss would result . the goodwill impairment loss would be the amount by which the carrying value of the reporting unit , including goodwill , exceeds its fair value , limited to the total amount of goodwill allocated to that reporting unit . the fair value of a reporting unit is based on discounted estimated future cash flows . the fair value is also benchmarked against a market approach using the guideline public companies method . the assumptions used to estimate fair value include management 's best estimates of future growth rates , operating cash flows , capital expenditures and discount rates over an estimate of the remaining operating period at the reporting unit level . refer to the discussion under the heading “ purification solutions goodwill and long-lived assets impairment charges ” for details on the purification solutions goodwill impairment test and the resulting charge recorded in the second quarter of fiscal 2018 and refer to note g of our notes to the consolidated financial statements for the results of our annual goodwill impairment test performed as of may 31 , 2018. long-lived assets impairment our long-lived assets primarily include property , plant and equipment , intangible assets , long-term investments and assets held for rent . the carrying values of long-lived assets are reviewed for impairment whenever events or changes in business circumstances indicate that the carrying amount of an asset may not be recoverable . story_separator_special_tag we believe total segment ebit , which reflects the s um of ebit from our four reportable segments , provides useful supplemental information for our investors as it is an important indicator of our operational strength and performance , allows investors to see our results through the eyes of management , and pr ovides context for our discussion of individual business segment performance . total segment ebit should not be considered an alternative for income ( loss ) from continuing operations before income taxes and equity in earnings of affiliated companies , which is the most directly comparable gaap financial measure . a reconciliation of total segment ebit to income ( loss ) from continuing operations before income taxes and equity in earnings of affiliated companies is provided under the heading “ fiscal 2018 compare d to fiscal 2017 and fiscal 2017 compared to fiscal 2016—by business segment ” . investors should consider the limitations associated with this non-gaap measure , including the potential lack of comparability of this measure from one company to another . in calculating total segment ebit , we exclude from our income ( loss ) from continuing operations before income taxes and equity in earnings of affiliated companies ( i ) items of expense and income that management does not consider representative of our fundamental on-going segment results , which we refer to as “ certain items ” , and ( ii ) items that , because they are not controlled by the business segments and primarily benefit corporate objectives , are not allocated to our business segments , such as interest expense and other corporate costs , which include unallocated corporate overhead expenses such as certain corporate salaries and headquarter expenses , plus costs related to special projects and initiatives , which we refer to as “ other unallocated items ” . management believes excluding the items identified as certain items facilitates operating performance comparisons from period to period by eliminating differences caused by the existence and timing of certain expense and income items that would not otherwise be apparent on a gaap basis and also facilitates an evaluation of our operating performance without the impact of these costs or benefits . the items of income and expense that we have excluded from total segment ebit , as applicable , but that are included in our gaap income ( loss ) from continuing operations before income taxes and equity in earnings of affiliated companies , as applicable , are described below . asset impairment charges , which primarily include charges associated with an impairment of goodwill or other long-lived assets . global restructuring activities include costs or benefits associated with cost reduction initiatives or plant closures , which primarily relate to ( i ) employee termination costs , ( ii ) asset impairment charges associated with restructuring actions , ( iii ) costs to close facilities , including environmental costs and contract termination penalties and ( iv ) gains realized on the sale of land or equipment associated with restructured plants or locations . inventory reserve adjustment , which resulted from an evaluation performed as part of an impairment analysis . acquisition and integration-related charges , which include transaction costs , redundant costs incurred during the period of integration , and costs associated with transitioning certain management and business processes to our processes . legal and environmental reserves and matters , which consist of costs or benefits for matters typically related to former businesses or that are otherwise incurred outside of the ordinary course of business . gains ( losses ) on sale of investments , which primarily relate to the sale of investments accounted for using the cost method . non-recurring gains ( losses ) on foreign exchange , which primarily relate to the impact of controlled currency devaluations on our net monetary assets denominated in that currency . executive transition costs , which include incremental charges , including stock compensation charges , associated with the retirement or termination of employment of senior executives of the company . employee benefit plan settlement charges , which consist of the costs associated with transferring the obligations and assets held by one of our defined benefit plans to a multi-employer plan . 30 drivers of demand and key factors affecting p rofitability drivers of demand and key factors affecting our profitability differ by segment . in reinforcement materials , longer term demand is driven primarily by : i ) the number of vehicle miles driven globally ; ii ) the number of original equipment and replacement tires produced ; and iii ) the number of automotive builds . over the past several years , operating results have been driven by a number of factors , including : i ) increases or decreases in our sales volumes driven by changes in production levels for tires or industrial rubber products and the level at which we service that demand ; ii ) changes in raw material costs and our ability to adjust the sales price for our products commensurate with changes in raw material costs ; iii ) changes in pricing and product mix , which includes customer pricing as well as the mix of products sold or the region in which they are sold ; iv ) global and regional capacity utilization for carbon black ; v ) fixed cost savings achieved through restructuring and other cost saving activities ; vi ) the growth of our volumes and market position in emerging economies ; vii ) capacity management and technology investments , including the impact of energy utilization and yield improvement technologies at our manufacturing facilities ; and viii ) royalties and technology payments related to our patented elastomer composites technology that is used in tire applications . in performance chemicals , longer term demand is driven primarily by the construction and infrastructure , automotive , electronics and consumer products industries . in recent years , operating results in performance chemicals have been driven by : i

cash flows from investing activities in fiscal 2018 , investing activities consumed $ 246 million , which was primarily driven by $ 64 million of cash paid for our specialty compounds acquisition of tech blend , net of cash acquired of $ 1 million , and capital expenditures of $ 229 million . these capital expenditures were for sustaining and compliance capital projects at our operating facilities as well as capacity expansion capital expenditures in reinforcement materials and performance chemicals . offsetting these amounts was an inflow of cash related to the sales of land at our former sites in merak , indonesia , and thane , india and proceeds from the sale of shares of a cost method investment in asia . in fiscal 2017 , capital expenditures were $ 147 million . capital expenditures were primarily related to sustaining and compliance capital projects at our operating facilities . in fiscal 2016 , capital expenditures were $ 112 million . major capital project expenditures were related to sustaining and compliance activities . capital expenditures for fiscal 2019 are expected to be between $ 250 million and $ 300 million . our planned capital spending program for fiscal 2019 is primarily for sustaining , compliance and improvement capital projects at our operating facilities as well as capacity expansion capital expenditures in reinforcement materials and performance chemicals . 39 cash flows from financing activities financing activities consumed $ 141 million of cash in fiscal 2018 compared to $ 133 million in fiscal 2017 and $ 184 million in fiscal 2016. the use of cash in fiscal 2018 was primarily related to cash dividends paid to common stockholders of $ 80 million , purchases of common stock of $ 142 million , and cash dividends paid to noncontrolling interests of $ 21 million . this was offset by an increase in our overall debt balance of $ 80 million .
