further insurance recoveries will be recorded when considered probable for recovery . 2019 overview sales for 2019 were $ 2.3 billion , a 12 % decrease from sales of $ 2.6 billion in 2018. during 2019 , sales to customers in our various industry sectors fluctuated from 2018 as follows : · industrials decreased by 8 % , · a & d increased by 6 % , · medical increased by 14 % , · semi-cap decreased by 22 % , · computing decreased by 38 % , and · telecommunications decreased by 12 % . the overall revenue decrease was due primarily to our planned exit of a legacy computing contract which was completed in 2019 ( as discussed below ) , in addition to the decline in the overall semi-cap market , reduced revenues 33 from other computing and telecommunications customers and the impact of the ransomware incident ( as discussed below ) . our sales depend on the success of our customers , some of which operate in businesses associated with rapid technological change and consequent product obsolescence . developments adverse to our major customers or their products , or the failure of a major customer to pay for components or services , can adversely affect us . a substantial percentage of our sales are made to a small number of customers , and the loss of a major customer , if not replaced , would adversely affect us . sales to our ten largest customers represented 38 % and 44 % of our sales in 2019 and 2018 , respectively . in 2019 , there was no single customer with sales over 10 % of our sales . in 2018 , sales to international business machines corporation ( ibm ) represented 13 % of our sales . as part of our ongoing process to review contracts that are marginal and dilutive to our gross margin , we made the decision to not renew the contract with a large computing customer that was to expire at the end of 2019. during the second quarter of 2019 , we completed the final build out of this legacy contract and in the third quarter had an immaterial amount of revenue from this contract as the transition was completed . during 2019 , we incurred an $ 11.0 million charge for the write-down of inventory and a provision for accounts receivable associated with the insolvency of a customer . these charges increased cost of sales by $ 0.9 million and selling , general and administrative expenses by $ 10.1 million . in 2019 , we also recovered $ 1.7 million of amounts written down in 2018 associated with the insolvency of another customer . we experience fluctuations in gross profit from period to period . different programs contribute different gross profits depending on the type of services involved , location of production , size of the program , complexity of the product and level of material costs associated with the various products . moreover , new programs can contribute relatively less to our gross profit in their early stages when manufacturing volumes are usually lower , resulting in inefficiencies and unabsorbed manufacturing overhead costs . in addition , a number of our new and higher-volume programs remain subject to competitive constraints that can exert downward pressure on our margins . during periods of low production volume , we generally have idle capacity and reduced gross profit . gross profit can also be impacted by other situations , such as the ransomware incident experienced in 2019. we have undertaken initiatives to restructure our business operations with the intention of improving utilization and reducing costs . during 2019 , we recognized $ 8.5 million of restructuring charges in connection with the announced closure of two facilities and other reductions in workforce of certain facilities primarily in the americas . in addition , we incurred $ 4.6 million in charges primarily related to our ceo transition and our 2019 proxy activity . during 2019 , we incurred $ 7.7 million in ransomware incident related costs , net of estimated insurance recoveries . results of operations the following table presents the percentage relationship that certain items in our consolidated statements of income bear to sales for the periods indicated . the financial information and the discussion below should be read in conjunction with the consolidated financial statements and notes thereto in item 8 of this report . 34 replace_table_token_7_th 2019 compared with 2018 sales as noted above , sales decreased 12 % in 2019. the percentages of our sales by sector were as follows : replace_table_token_8_th industrials . 2019 sales decreased 8 % to $ 453.6 million from $ 493.1 million in 2018. the decreases were primarily from softer demand from customers in the industrial transportation market and the ramp delays from previously booked new programs . aerospace and defense . 2019 sales increased 6 % to $ 431.9 million from $ 406.4 million in 2018 primarily due to increased demand from our defense customers . medical . 2019 sales increased 14 % to $ 448.2 million from $ 394.0 million in 2018 from higher demand and program ramps from new and existing customers . semiconductor capital equipment . 2019 sales decreased 22 % to $ 277.8 million from $ 355.0 million in 2018. the decrease reflected is due to declines in demand throughout the broader semi-capital equipment market . computing . 2019 sales decreased 38 % to $ 361.2 million from $ 580.8 million in 2018. the decrease is primarily due from our planned exit of a legacy computing contract that was completed in 2019 . 35 telecommunications . 2019 sales decreased 12 % to $ 295.4 million from $ 337.2 million in 2018. the decrease is primarily due to decreased demand from existing customers . our international operations are subject to the risks of doing business abroad . story_separator_special_tag for these contracts , the selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided . we use a cost-based input measurement of progress because is best represents the transfer of assets to the customer . for our other contracts , revenue is recognized upon transfer of control of the product or service , which is generally upon shipment or delivery pending on the terms of the underlying contract . revenue from design , development and engineering services is generally recognized over time as the services are performed . generally , there are no subjective customer acceptance requirements or further obligations related to goods of services provided . our contracts with customer do not allow for a general right of return . income taxes we estimate our income tax provision in each of the jurisdictions where we operate , including estimating exposures related to uncertain tax positions . we must also make judgments regarding the ability to realize our deferred tax assets . we record a valuation allowance to reduce our deferred tax assets to the amount that we believe is more likely than not to be realized . our valuation allowance as of december 31 , 2019 of $ 16.0 million primarily relates to deferred tax assets from our foreign and u.s. state net operating loss tax carryforwards of $ 15.4 million . differences in our future operating results as compared to the estimates utilized in the determination of the valuation allowances could result in adjustments in valuation allowances in future periods . for example , a significant increase in our operations in the united states , future accretive acquisitions in the united states and any movement in the mix of profits from our international operations to the united states would result in a reduction in the valuation allowance and would increase income in the period such determination was made . alternatively , significant economic downturns in the united states generating additional operating loss carryforwards and potential movements in the mix of profits to international locations would result in an increase in the valuation allowance and would decrease income in the period such determination was made . on december 22 , 2017 , the sec staff issued staff accounting bulletin no . 118 ( sab 118 ) , which provides guidance on accounting for the tax effects of the u.s. tax reform . sab 118 provided a measurement period that would not extend beyond one year from the u.s. tax reform enactment date for companies to complete their accounting of the impact on income taxes . until the accounting was complete , companies could record provisional estimates . as a result of the u.s. tax reform , we recorded provisional amounts in relation to the accounting of the transition tax in 2017. we have finalized our accounting for sab 118 as of december 31 , 2018 within the measurement period . see note 10 to the consolidated financial statements in item 8 of this report . 40 we are subject to examination by tax authorities for different periods in various u.s. and foreign tax jurisdictions . during the course of such examinations , disputes may occur as to matters of fact and or law . in most tax jurisdictions the passage of time without examination will result in the expiration of applicable statutes of limitations , thereby precluding the taxing authority from examining the relevant tax period ( s ) . we believe that we have adequately provided for our tax liabilities . impairment of long-lived assets and goodwill long-lived assets , such as property , plant , and equipment and purchased intangibles subject to amortization , are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable . the recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset . if the carrying amount of an asset exceeds its estimated undiscounted future cash flows , an impairment charge is recognized by the amount that the carrying amount of the asset exceeds the fair value of the asset . goodwill is tested for impairment on an annual basis , at a minimum , and whenever events and circumstances indicate that the carrying amount may be impaired . circumstances that may lead to impairment include unforeseen decreases in future performance or industry demand or the restructuring of our operations as a result of a change in our business strategy . we perform a qualitative assessment to determine if goodwill is potentially impaired . if the qualitative assessment indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount , or if we elect not to perform a qualitative assessment , then we would be required to perform a quantitative impairment test for goodwill . this two-step process involves determining the fair values of the reporting units and comparing those fair values to the carrying values , including goodwill , of the reporting unit . an impairment loss would be recognized to the extent that the carrying amount exceeds the asset 's fair value . for purposes of performing our goodwill impairment assessment , our reporting units are the same as our operating segments as defined in note 15 to the consolidated financial statements in item 8 of this report . as of december 31 , 2019 and 2018 , we had goodwill of approximately $ 192.1 million , respectively , associated with our americas and asia business segments . based on our qualitative assessments of goodwill as of december 31 , 2019 , 2018 and 2017 , we concluded that it was more likely than not that the fair value of our americas and asia business segments were greater

liquidity and capital resources we have historically financed our organic growth and operations through funds generated from operations and occasional borrowings under our revolving credit facility . cash and cash equivalents and restricted cash totaled $ 364.0 million at december 31 , 2019 and $ 458.1 million at december 31 , 2018 , of which $ 197.8 million and $ 154.4 million , respectively , were held outside the u.s. in various foreign subsidiaries . during 2019 and 2018 , we repatriated $ 52.1 million and $ 560.6 million , respectively , of foreign earnings to the u.s. cash provided by operating activities was $ 93.1 million in 2019. the cash provided by operations during 2019 consisted primarily of $ 23.4 million of net income , adjusted for $ 48.4 million of depreciation and amortization , a $ 134.9 million decrease in accounts receivable , a $ 5.2 million increase in inventories , a $ 10.3 million decrease in income tax liabilities , net and a $ 121.9 million decrease in accounts payable . the decrease in accounts receivable and accounts payable was primarily a result of the impact of our exit from a legacy computing contract described above . working capital was $ 0.7 billion at december 31 , 2019 and $ 0.9 billion at december 31 , 2018. we purchase components only after customer orders or forecasts are received , which mitigates , but does not eliminate , the risk of loss on inventories . supplies of electronic components and other materials used in operations are subject to industry-wide shortages . in certain instances , suppliers may allocate available quantities to us . if shortages of these components and other material supplies used in operations occur , vendors may not ship the quantities we need for production , and we may be forced to delay shipments , which can increase backorders and impact cash flows . cash used in investing activities was $ 34.9 million in 2019 primarily due to purchases of additional property , plant and equipment totaling $ 32.6 million .
