Organization Consolidation And Presentation Of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Use of estimates The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. The Company evaluates these estimates on a regular basis and bases them on historical experience and on various assumptions that the Company believes are reasonable. Actual results could differ from the estimates. Principles of consolidation The Consolidated Financial Statements include the accounts of the Company, its wholly-owned subsidiaries, majority-owned subsidiaries in which no substantive participating rights are held by minority stockholders and variable interest entities if the Company is the primary beneficiary. All intercompany accounts and transactions have been eliminated. The Consolidated Financial Statements include 100% of the assets and liabilities of majority-owned subsidiaries and the ownership interest of minority investors is recorded as noncontrolling interest. Investments in 20% through 50% owned affiliated companies are accounted under the equity method where the Company exercises significant influence over operating and financial affairs of the investee and is not the primary beneficiary. Investments in less than 20% owned companies are recorded as cost method investments, available for sale securities or trading securities, unless the Company has significant influence. Segment reporting Operating segments are based on components of the Company that engage in business activity that earns revenue and incurs expenses and (a) whose operating results are regularly reviewed by the Company’s chief operating decision maker to make decisions about resource allocation and performance and (b) for which discrete financial information is available. The Company has two reportable segments: Technology Solutions and Concentrix. The Technology Solutions segment represents an aggregation of the Technology Solutions United States, Canada, Japan and Latin America operating segments. The Technology Solutions segment distributes peripherals, IT systems, including data center servers, system components, software, networking, communications, security equipment, consumer electronics (“CE”) and complementary products to a variety of customers, including value-added resellers, system integrators and retailers. The segment also designs and integrates energy efficient data center servers built specific to the customers' data center environment. The Concentrix segment offers a range of technology-enabled global business outsourcing services focused on customer engagement, process optimization and front and back-office automation to clients in ten industry verticals. The portfolio of services offered comprises end-to-end process outsourcing services that are delivered through omni-channels including both voice and non-voice. Cash and cash equivalents The Company considers all highly liquid debt instruments purchased with an original maturity or remaining maturity at the date of purchase of three months or less to be cash equivalents. Cash equivalents consist principally of money market deposit accounts and money market funds Allowance for doubtful accounts The allowance for doubtful accounts is an estimate to cover the losses resulting from the inability of customers to make payments for outstanding balances. In estimating the required allowance, the Company takes into consideration the overall quality and aging of the accounts receivable, credit evaluations of customers’ financial condition and existence of credit insurance. The Company also evaluates the collectability of accounts receivable based on specific customer circumstances, current economic trends, historical experience with collections and any value and adequacy of collateral received from customers. Inventories Inventories are stated at the lower of cost and net realizable value. Cost is computed based on the weighted-average method. Inventories are comprised of finished goods and work-in-process. Finished goods include products purchased for resale, system components purchased for both resale and for use in the Company’s systems design and integration business, and completed systems. Work-in-process inventories are not material to the Consolidated Financial Statements. Derivative Financial Instruments The Company accounts for its derivative instruments as either assets or liabilities and carries them at fair value. For derivative instruments that hedge the exposure to variability in expected future cash flows that are designated as cash flow hedges, the gain or loss on the derivative instrument is reported as a component of “Accumulated other comprehensive income (loss),” in stockholders’ equity and reclassified into earnings in the same line associated with the forecasted transactions, in the same period or periods during which the hedged transaction affects earnings. To receive hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions. For derivative instruments that are not designated as hedges, gains and losses on derivative instruments are reported in the Consolidated Statements of Operations in the current period. Property and equipment Property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method based upon the shorter of the estimated useful lives of the assets, or the lease term of the respective assets, if applicable. Maintenance and repairs are charged to expense as incurred, and improvements are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation and amortization are removed from the accounts and any resulting gain or loss is reflected in operations in the period realized. The ranges of estimated useful lives for property and equipment categories are as follows: Equipment and Furniture 3 - 10 years Software 3 - 7 years Leasehold improvements 2 - 15 years Buildings and building improvements 10 - 40 years Business Combinations The purchase price is allocated to the assets acquired, liabilities assumed, and non-controlling interests in the acquired entity generally based on their fair values at the acquisition date. The excess of the fair value of purchase consideration over the fair value of these assets acquired, liabilities assumed and non-controlling interests in the acquired entity is recorded as goodwill. The primary items that generate goodwill include the value of the synergies between the acquired entity and the Company and the value of the acquired assembled workforce, neither of which qualify for recognition as an intangible asset. Amounts recorded in a business combination may change during the measurement period, which is a period not to exceed one year from the date of acquisition, as additional information about conditions existing at the acquisition date becomes available. The Company includes the results of operations of the acquired business in the Consolidated Financial Statements prospectively from the date of acquisition. Acquisition-related charges are recognized separately from the business combination and are expensed as incurred. These charges primarily include, direct third-party professional and legal fees, and integration-related costs. Goodwill and intangible assets The values assigned to intangible assets are based on estimates and judgment regarding expectations for the success and life cycle of products and technologies and length of customer relationships acquired in a business combination. Purchased intangible assets are amortized over the useful lives based on estimates of the use of the economic benefit of the asset or on the straight-line amortization method. The Company allocates goodwill to reporting units based on the reporting unit expected to benefit from the business combination and tests for impairment annually in the fourth quarter or more frequently if events or changes in circumstances indicate that it may be impaired. Goodwill is tested for impairment at the reporting unit level by first performing a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying value. The factors that are considered in the qualitative analysis include macroeconomic conditions, industry and market considerations, cost factors such as increases in product cost, labor, or other costs that would have a negative effect on earnings and cash flows; and other relevant entity-specific events and information. If the reporting unit does not pass the qualitative assessment, then the reporting unit’s carrying value is compared to its fair value. The fair values of the reporting units are estimated using market and discounted cash flow approaches. The assumptions used in the market approach are based on the value of a business through an analysis of sales and other multiples of guideline companies and recent sales or offerings of a comparable entity. The assumptions used in the discounted cash flow approach are based on historical and forecasted revenue, operating costs, future economic conditions, and other relevant factors. Goodwill is considered impaired if the carrying value of the reporting unit exceeds its fair value and the excess is recognized as an impairment loss. No goodwill impairment has been identified for any of the years presented. Intangible assets consist primarily of customer relationships and lists, vendor lists, technology and trade names. Amortization is based on the pattern in which the economic benefits of the intangible assets will be consumed or on a straight line basis when the consumption pattern is not apparent over the following useful lives: Customer relationships and lists 4 - 15 years Vendor lists 10 years Technology 5 years Other intangible assets 1- 10 years Impairment of long-lived assets The Company reviews the recoverability of its long-lived assets, such as intangible assets, property and equipment and certain other assets, when events or changes in circumstances occur that indicate the carrying value of the asset or asset group may not be recoverable. The assessment of possible impairment is based on the Company’s ability to recover the carrying value of the asset or asset group from the expected future pre-tax cash flows, undiscounted and without interest charges, of the related operations. If these cash flows are less than the carrying value of such assets, an impairment loss is recognized for the difference between estimated fair value and carrying value. Concentration of credit risk Financial instruments that potentially subject the Company to significant concentration of credit risk consist principally of cash and cash equivalents, accounts receivable and derivative instruments. The Company’s cash and cash equivalents and derivative instruments are transacted and maintained with financial institutions with high credit standing, the compositions and maturities of which are regularly monitored by management. Through November 30, 2018, the Company has not experienced any credit losses on such deposits and derivative instruments. Accounts receivable include amounts due from customers and original equipment manufacturer (“OEM”) vendors primarily in the technology industry. The Company performs ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended when deemed necessary, but generally requires no collateral. The Company also maintains allowances for potential credit losses. In estimating the required allowances, the Company takes into consideration the overall quality and aging of the receivable portfolio, the existence of a limited amount of credit insurance and specifically identified customer and vendor risks. Through November 30, 2018, such losses have been within management’s expectations. In fiscal years 2018, 2017 and 2016, one customer accounted for 17%, 21% and 12%, respectively of the Company’s consolidated revenue. Products purchased from the Company’s largest OEM supplier, HP Inc., accounted for approximately 12%, 13% and 17% of the consolidated revenue for fiscal years 2018, 2017 and 2016, respectively. As of November 30, 2018, there was no customer which represented more than 10% of the total accounts receivable balance. As of November 30, 2017, one customer comprised 12% of the total accounts receivable balance. Book overdrafts Book overdrafts, representing checks issued in excess of balances on deposit in the applicable bank accounts and which have not been paid by the applicable bank at the balance sheet date are classified as “Borrowings, current” in the Company’s Consolidated Balance Sheets. Under the terms of the Company’s banking arrangements, the respective financial institutions are not legally obligated to honor the book overdraft balances. The Company’s policy is to report the change in book overdrafts as a financing activity in the Consolidated Statements of Cash Flows. Revenue recognition Products revenue represents revenue from the Company’s Technology Solutions segment and services revenue represents revenue from the Company’s Concentrix segment. Technology Solutions The Company generally recognizes revenue on the sale of hardware and software products when they are shipped or delivered and on services when they are performed, if persuasive evidence of an arrangement exists, the sales price is fixed or determinable, collection of resulting accounts receivable is reasonably assured, risk of loss and title have transferred and product returns are reasonably estimable. Binding purchase orders from customers together with agreement to the Company's terms and conditions of sale by way of an executed agreement or other signed document constitutes evidence of an arrangement. Where product acceptance provisions exist, assuming all other revenue recognition criteria are met, revenue is recognized upon the earlier of shipment/delivery for products that have been demonstrated to meet product specifications, customer acceptance or the lapse of acceptance provisions. Provisions for sales returns and allowances are estimated based on historical data and are recorded concurrently with the recognition of revenue. These provisions are reviewed and adjusted periodically by the Company. Revenue is presented net of taxes collected from customers and remitted to government authorities. Revenue is reduced for early payment discounts and volume incentive rebates offered to customers. The Company recognizes revenue on a net basis on certain contracts, including service contracts, post-contract software support services and extended warranty contracts, where it is not the primary obligor, by recognizing the margins earned in revenue with no associated cost of revenue. Concentrix The Company recognizes revenue from services contracts when evidence of an arrangement exists, services are delivered, fees are fixed or determinable and collectability is reasonably assured. Service contracts may be based on a fixed price or on a fixed unit-price per transaction or other objective measure of output. Revenue on fixed price contracts is recognized on a straight-line basis over the term of the contract as services are provided. Revenue on unit-price transactions is recognized using an objective measure of output including staffing hours or the number of transactions processed by service agents. Customer contract terms can range from less than one year to more than five years. Revenue is reported net of any revenue-based taxes assessed by governmental authorities that are imposed on and concurrent with specific revenue-producing transactions. Cost of Revenue Cost of products revenue represents cost of the Company’s Technology Solutions segment and cost of services revenue represents cost of the Company’s Concentrix segment. Technology Solutions Cost of revenue includes the product price paid to OEM suppliers, net of any incentives, rebates, price protection and purchase discounts received from the OEM suppliers. Cost of revenue also consists of provisions for inventory losses and write-downs, shipping and handling costs and royalties due to OEM vendors. In addition, cost of revenue includes the cost of materials, labor and overhead and warranty for design and integration activities. Concentrix Recurring direct operating costs for services are recognized as incurred. Cost of services revenue consists primarily of personnel costs. Where a contract requires an up-front investment, which typically includes transition and set-up costs related to systems and processes, these amounts are deferred and amortized on a straight-line basis over the expected period of benefit, not to exceed the fixed term of the contract. The Company performs periodic reviews to assess the recoverability of deferred contract transition and setup costs. This review is done by comparing the estimated minimum remaining undiscounted cash flows of a contract to the unamortized contract costs. If such minimum undiscounted cash flows are not sufficient to recover the unamortized costs, an impairment loss is recognized for the difference between the estimated fair value and the carrying value. If a cash flow deficiency remains after reducing the carrying amount of the deferred costs, the Company evaluates any remaining long-lived assets related to that contract for impairment. Selling, General and Administrative expenses Selling, general and administrative expenses are charged to income as incurred. Expenses of promoting and selling products and services are classified as selling expense and include such items as compensation, sales commissions and travel. General and administrative expenses include such items as compensation, cost of warehouse, delivery centers and other non-integration facilities, legal and professional costs, office supplies, non-income taxes, insurance and utility expenses. In addition, selling, general and administrative expenses include other operating items such as allowances for credit losses, depreciation and amortization of non-technology related intangible assets. OEM supplier programs Funds received from OEM suppliers for volume promotion programs, price protection and product rebates are recorded as adjustments to cost of revenue and/or the carrying value of inventories, as appropriate. Where there is a binding agreement, the Company tracks vendor promotional programs for volume discounts on a program-by-program basis and records them as a reduction to cost of revenue based on a systematic and rational allocation. The Company monitors the balances of vendor receivables on a quarterly basis and adjusts the balances due for differences between expected and actual sales volume. Vendor receivables are generally collected through reductions authorized by the vendor to accounts payable. Funds received for specific marketing and infrastructure reimbursements, net of related costs, are recorded as adjustments to “Selling, general and administrative expenses,” and any excess reimbursement amount is recorded as an adjustment to cost of revenue. Royalties The Company’s software product purchases include products licensed from OEM vendors, which are subsequently distributed to resellers. Royalties to OEM vendors are accrued and recorded in cost of revenue when software products are shipped and revenue is recognized. Warranties The Company’s OEM suppliers generally warrant the products distributed by the Company and allow returns of defective products. The Company generally does not independently warrant the products it distributes; however, the Company does warrant the following: (1) products that it builds to order from components purchased from other sources; and (2) its services with regard to products that it assembles for its customers. To date neither warranty expense, nor the accrual for warranty costs has been material to the Company’s Consolidated Financial Statements. Advertising Costs related to advertising and product promotion expenditures are charged to “Selling, general and administrative expenses” as incurred and are primarily offset by OEM marketing reimbursements. To date, net costs related to advertising and promotion expenditures have not been material. Income taxes The asset and liability method is used in accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts in the financial statements using enacted tax rates and laws that will be in effect when the difference is expected to reverse. Tax on global low-taxed intangible income is accounted for as a current expense in the period in which the income is includable in a tax return using the “period cost” method. The Company recognizes tax benefits from uncertain tax positions only if that tax position is more likely than not to 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 positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. The Company recognizes interest and penalties related to unrecognized tax benefits in the provisions for income taxes. Foreign currency translations The financial statements of the Company’s foreign subsidiaries whose functional currencies are the local currencies are translated into U.S. dollars for consolidation as follows: assets and liabilities at the exchange rate as of the balance sheet date, stockholders’ equity at the historical rates of exchange, and income and expense amounts at the average exchange rate for the month. Translation adjustments resulting from the translation of the subsidiaries’ accounts are included in “Accumulated other comprehensive income (loss).” Transactions denominated in currencies other than the applicable functional currency are converted to the functional currency at the exchange rate on the transaction date. At period end, monetary assets and liabilities are remeasured to the functional currency using exchange rates in effect at the balance sheet date. Non-monetary assets and liabilities are remeasured at historical exchange rates. Gains and losses resulting from foreign currency transactions are included within “Other income (expense), net.” Comprehensive income Comprehensive income is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. The primary components of comprehensive income for the Company include net income, foreign currency translation adjustments arising from the consolidation of the Company’s foreign subsidiaries, unrealized gains and losses on the Company’s available-for-sale securities, unrealized gains and losses on cash flow hedges and the changes in unrecognized pension and post-retirement benefits. Share-based compensation The Company accounts for stock-based payment transactions in which the Company receives employee services in exchange for equity instruments of the Company. Stock-based compensation cost for stock options, restricted stock awards and units, performance restricted stock units and employee stock purchase plans is determined based on the fair value at the measurement date. The Company recognizes stock-based compensation cost as expense for awards other than its performance-based restricted stock units ratably on a straight-line basis over the requisite service period. The Company recognizes stock-based compensation cost associated with its performance based restricted stock units over the requisite service period if it is probable that the performance conditions will be satisfied. Effective fiscal year 2018, the Company accounts for expense reductions that result from the forfeiture of unvested awards in the period that the forfeitures occur. Prior to fiscal year 2018, the Company estimated forfeitures and only recorded compensation costs for those awards that were expected to vest. Pension and post-retirement benefits The funded status of the Company’s pension and other postretirement benefit plans is recognized in the Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of plan assets and the benefit obligation at November 30, the measurement date. For defined benefit pension plans, the benefit obligation is the projected benefit obligation ("PBO") and, for the other postretirement benefit plans, the benefit obligation is the accumulated postretirement benefit obligation ("APBO"). The PBO represents the actuarial present value of benefits expected to be paid upon retirement. For active plans, the present value reflects estimated future compensation levels. The APBO represents the actuarial present value of postretirement benefits attributed to employee services already rendered. The fair value of plan assets represents the current market value of assets held by an irrevocable trust fund for the sole benefit of participants. The measurement of the benefit obligation is based on the Company’s estimates and actuarial valuations. These valuations reflect the terms of the plans and use participant-specific information such as compensation, age and years of service, as well as certain key assumptions that require significant judgment, including, but not limited to, estimates of discount rates, expected return on plan assets, inflation, rate of compensation increases, interest crediting rates and mortality rates. The assumptions used are reviewed on an annual basis. The Company records pension expense related to multi-employer plans based on the amount of contributions that are contractually owed during the period based on the service provided by the employee. Earnings per common share Earnings per share is calculated using the two-class method. The two-class method is an earnings allocation proportional to the respective ownership among holders of common stock and participating securities. Basic earnings per common share is computed by dividing net income attributable to the Company’s common stockholders by the weighted average of common shares outstanding during the period. Diluted earnings per common share also considers the dilutive effect of in-the-money stock options and restricted stock units, calculated using the treasury stock method. Treasury Stock Repurchases of shares of common stock are accounted for at cost, which includes brokerage fees, and are included as a component of stockholders’ equity in the Consolidated Balance Sheets. Recently adopted accounting pronouncements In August 2018, the Financial Accounting Standard Board (the “FASB”) issued guidance clarifying the accounting for capitalizing implementation costs incurred by a customer in a cloud computing arrangement that is a service contract. Under the new guidance, implementation costs related to a cloud computing arrangement will be deferred or expensed as incurred, in accordance with the existing guidance for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The amendments also require the customer to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement, which includes reasonably certain renewals. The guidance is effective for interim and annual reporting periods beginning after December 15, 2019 and early adoption is permitted. The Company adopted this guidance prospectively in the third quarter of fiscal year 2018. The adoption did not have a material impact on the Company's Consolidated Financial Statements. In March 2016, the FASB, issued guidance which changes the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification in the Consolidated Statement of Cash Flows. The guidance is effective for interim and annual periods beginning after December 15, 2016 and early adoption is permitted. The Company adopted this guidance prospectively, during the first quarter of fiscal year 2018. The adoption did not have a material impact on the Company's Consolidated Financial Statements. Recently issued accounting pronouncements In August 2018, the FASB issued new guidance to add, remove, and clarify disclosure requirements related to defined benefit pension and other postretirement plans. The amendment requires the Company to disclose the weighted-average interest crediting rates used in cash balance pension plans. It also requires the Company to disclose the reasons for significant changes in the benefit obligation or plan assets including significant gains and losses affecting the benefit obligation for the period. This standard is effective for fiscal years ending after December 15, 2020 and early adoption is permitted. The adoption is not expected to have a material impact on the Company's Consolidated Financial Statements. In August 2018, the FASB issued guidance to improve the effectiveness of fair value measurement disclosures by removing or modifying certain disclosure requirements and adding other requirements. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. Certain amendments should be applied prospectively, while all other amendments should be applied retrospectively to all periods presented. The Company is currently evaluating the impact of the new guidance. In February 2018, the FASB issued guidance that permits the Company to reclassify disproportionate tax effects in accumulated other comprehensive income caused by the Tax Cuts and Jobs Act of 2017 to retained earnings. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact of the new guidance. In June 2016, the FASB issued a new credit loss standard that replaces the incurred loss impairment methodology in current GAAP. The new impairment model requires immediate recognition of estimated credit losses expected to occur for most financial assets and certain other instruments. It is effective for annual reporting periods beginning after December 15, 2019 and interim periods within those annual periods. Early adoption for fiscal years beginning after December 15, 2018 is permitted. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first effective reporting period. The Company is currently evaluating the impact of the new guidance. In February 2016, the FASB issued a new standard which revises various aspects of accounting for leases. The most significant impact to the Company’s Consolidated Financial Statements relates to the recognition by a lessee of a right-of-use asset and a lease liability for virtually all of its leases other than short-term leases. The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment, such as for initial direct costs. Consistent with current guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification. For income statement purposes, operating leases will result in a straight line expense while finance leases will result in a front-loaded expense pattern. This accounting standard will be applicable to the Company at the beginning of its first quarter of fiscal year 2020 using a modified retrospective approach and early adoption is permitted. The Company expects that most of its operating lease commitments will be subject to the new standard and be recognized as operating lease liabilities and right-of-use assets upon adoption. The Company is currently evaluating the impact of the adoption of this new standard on its Consolidated Financial Statements. In January 2016, the FASB issued new guidance which amends various aspects of the rec

Acquisitions	Fiscal 2018 acquisition On October 5, 2018, the Company acquired 100% of Convergys Corporation ("Convergys"), an Ohio Corporation, a customer experience outsourcing company, for a purchase price of $2,269,527, pursuant to a merger agreement dated June 28, 2018. The acquisition is related to the Company's Concentrix segment and is expected to add scale, diversify the revenue base, expand the Company's service delivery footprint and strengthen the Company’s leadership position as a top global provider of customer engagement services. The acquisition has been accounted for as a business combination. Under the merger agreement, at the completion of the acquisition, each outstanding Convergys common share converted into the right to receive $13.25 in cash and 0.1263 shares of common stock of the Company, plus cash in lieu of any fractional shares, without interest. In addition, the Company assumed Convergys outstanding employee stock-based awards, with each award to be settled in cash at $24.76 per award unit, less any applicable exercise price and without interest, in accordance with specified vesting terms. As indicated in Note 11 Purchase consideration: Fair value Cash $ 1,208,419 Stock consideration 1,017,329 Stock awards assumed 43,779 $ 2,269,527 The Company issued 11,511 shares of its common stock to Convergys shareholders, giving them an approximate 22% stake in the Company at the closing date, excluding prior holdings in the Company The preliminary purchase price allocation is as follows: Preliminary purchase price allocation: Preliminary Fair Value Cash, cash equivalents and restricted cash $ 169,988 Short-term investments 13,038 Accounts receivable, net (Gross accounts receivable: $558,888) 554,777 Other current assets 86,570 Property and equipment 214,565 Goodwill 1,361,429 Intangible assets 927,000 Deferred tax assets 31,547 Other assets 33,732 Borrowings, current (321,865 ) Accounts payable (59,720 ) Accrued compensation and benefits (213,455 ) Other accrued liabilities (255,267 ) Income taxes payable (17,311 ) Other long-term liabilities (136,446 ) Deferred tax liabilities (119,055 ) Purchase consideration $ 2,269,527 The identifiable intangible assets acquired and their estimated useful lives are summarized as follows: Preliminary fair value Weighted average useful Life Customer relationships $ 925,000 15 years Technology 2,000 5 years Total intangibles acquired $ 927,000 Amortization of customer relationships is recorded in “Selling, general and administrative expenses” and amortization of technology is recorded in “Cost of revenue” for “services.” The purchase price for the acquisition was allocated to the net tangible and intangible assets based on their preliminary fair values at the acquisition date. The excess of the purchase price over the preliminary net tangible assets and preliminary intangible assets was recorded as goodwill, and is attributed to the assembled workforce and the expected revenue and cost synergies due to the diversified revenue base and comprehensive service portfolio delivery capabilities resulting from the acquisition. Goodwill is not deductible for tax purposes. The preliminary allocation of the purchase price was based upon a preliminary valuation, and the Company's estimates and assumptions are subject to change within the measurement period. The primary areas of the preliminary purchase price allocation that are not yet finalized relate to the fair value of certain tangible assets acquired and liabilities assumed, the valuation of intangible assets acquired and related deferred income taxes. The Company expects to continue to obtain information for the purpose of determining the fair value of the net assets acquired at the acquisition date throughout the remainder of the measurement period. The Company’s Consolidated Statement of Operations for the year ended November 30, 2018 includes approximately $439,400 of revenue from Convergys. Earnings contributed by the acquired business are not separately identifiable due to the integration activities of the Company. Acquisition-related and integration expenses related to the Convergys acquisition were $37,490 during the year ended November 30, 2018 and consist of bridge financing commitment fees, professional and valuation services, severance and lease termination payments and other costs incurred to complete the acquisition and retention payments to integrate the business. These charges were recorded in "Selling, general and administrative expenses." The following unaudited pro forma financial information combines the unaudited Consolidated Results of Operations as if the acquisition of Convergys had occurred at the beginning of the periods presented. Pro forma adjustments include only the effects of events directly attributable to transactions that are factually supportable. The pro forma results contained in the table below include pro forma adjustments for amortization of acquired intangibles, interest expense incurred on borrowings to fund the acquisition, useful lives of fixed assets , The unaudited pro forma financial information, as presented below, is for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition and any borrowings undertaken to finance the acquisition had taken place at the beginning of fiscal periods presented.

The acquisition has been integrated into the Technology Solutions segment and is expected to strengthen the Company’s line card in the security, Unified Communications and Collaboration and networking markets, enhance the Company’s North American position and expand the Company’s footprint into Latin America. As part of the transaction, the Company entered into an agreement with Datatec whereby Westcon-Comstor Americas and Datatec will cooperate in the global deployment of solutions to certain global customers of Westcon-Comstor Americas and Datatec's distribution business outside the Americas for specified fees. The purchase price for the acquisition was allocated to net tangible and intangible assets based on their fair values as of the acquisition date, resulting in net tangible liabilities of $43,912, goodwill of $339,480 and intangible assets of $338,000, primarily comprising customer and vendor relationships. The excess of the purchase price over the net liabilities acquired was recorded as goodwill, and is attributed to the assembled workforce, expanded market opportunities due to a stronger line card and geographic expansion, and expected revenue and cost synergies. Goodwill of $5,748 On July 31, 2017, the Company acquired 100% of Tigerspike Pty Ltd, a digital products company incorporated in Australia, specializing in strategy, experience design, development and systems integration, for a purchase price of $67,014.

Share-Based Compensation	NOTE 5—SHARE-BASED COMPENSATION: The Company recognizes share-based compensation expense for all share-based awards made to employees and directors, including employee stock options, restricted stock awards, restricted stock units, performance-based restricted stock units and employee stock purchases, based on estimated fair values. The Company recorded share-based compensation expense in the Consolidated Statements of Operations for fiscal years 2018, 2017 and 2016 as follows: Fiscal Years Ended November 30, 2018 2017 2016 Total share-based compensation $ 22,767 $ 17,523 $ 14,023 Tax effect of share-based compensation (6,156 ) (6,167) (4,768 ) Net effect on net income $ 16,611 $ 11,356 $ 9,255 Substantially all of the share-based compensation expense was recorded in “Selling, general and administrative expenses” in the Consolidated Statements of Operations. Valuation Assumptions The Company estimates the fair value of share-based payment awards on the measurement date and recognizes as expense over the requisite service period in the Company’s financial statements. The Company uses the Black-Scholes valuation model to estimate fair value of stock options. The Black-Scholes option-pricing model was developed for use in estimating the fair value of short-lived exchange traded options that have no vesting restrictions and are fully transferable. In addition, option-pricing models require the input of highly subjective assumptions, including the option’s expected life and the price volatility of the underlying stock. The expected stock price volatility assumption was determined using historical volatility of the Company’s common stock. The fair value of stock awards is determined based on the stock price at the date of grant. For grants that do not accrue dividends or dividend equivalents, the fair value is the stock price reduced by the present value of estimated dividends over the vesting period. For performance-based restricted stock units, the grant-date fair value assumes that the targeted performance goals will be achieved. Over the performance period, the number of awards will be adjusted higher or lower based on the probability of achievement of performance goals. Through fiscal year 2017, the Company estimated forfeitures and only recorded compensation costs for those awards that were expected to vest. The assumptions for forfeitures were determined based on type of award and historical experience. Forfeiture assumptions were adjusted at the point in time a significant change is identified, with any adjustment recorded in the period of change, and the final adjustment at the end of the requisite service period to equal actual forfeitures. From fiscal year 2018, the Company accounts for expense reductions that result from the forfeiture of unvested awards in the period that the forfeitures occur. The following assumptions were used in the Black-Scholes valuation model in fiscal years 2018, 2017 and 2016: Fiscal Years Ended November 30, 2018 2017 2016 Stock option plan: Expected life (years) 6.0 5.9 5.8 Risk free interest rate 3.09 % 2.11 % 1.43 % Expected volatility 30.85 % 29.41 % 31.44 % Dividend yield 1.84 % 0.93 % 0.89 % A summary of the activities under the Company’s stock incentive plan is set forth below: Options Outstanding Shares available Number of shares Weighted- average exercise price per share Balances, November 30, 2017 1,340 617 $ 72.42 Restricted stock awards granted (248 ) — — Restricted stock units granted (77 ) — — Restricted stock cancelled/forfeited 72 — — Options granted (198 ) 198 $ 79.92 Options exercised — (35 ) $ 43.99 Balances, November 30, 2018 889 780 $ 75.62 Employee Stock Options The weighted-average grant-date fair values of the stock options granted during fiscal years 2018, 2017 and 2016 were $22.96, $36.92, and $32.66, respectively. The cash received from the exercise of options and the intrinsic values of options exercised during fiscal years 2018, 2017 and 2016 were as follows: Fiscal Years Ended November 30, 2018 2017 2016 Intrinsic value of options exercised $ 2,465 $ 3,856 $ 11,918 Cash received from exercise of options $ 1,561 $ 1,400 $ 5,157 The Company settles employee stock option exercises with newly issued common shares. As of November 30, 2018, the unamortized share-based compensation expense related to unvested stock options under the 2013 Stock Incentive Plan was $9,697 which will be recognized over an estimated weighted-average amortization period of 3.74 years. Restricted Stock Awards and Restricted Stock Units A summary of the changes in the Company’s non-vested restricted stock awards and stock units during fiscal year 2018 is presented below: Number of shares Weighted- average, grant- date fair value per share Non-vested as of November 30, 2017 701 $ 103.74 Awards granted 248 80.77 Units granted (1) 77 99.86 Awards and units vested (189) 88.21 Awards and units cancelled/forfeited (2) (72) 97.63 Non-vested as of November 30, 2018 764 $ 99.28 (1) For performance-based restricted stock units, the maximum number of shares that can be awarded upon full vesting of the grants is included. (2) For performance-based restricted stock units, the difference between maximum awards and the actual number of shares issued upon full vesting is included. As of November 30, 2018, there was $60,355 of total unamortized share-based compensation expense related to non-vested restricted stock awards and stock units granted under the 2013 Stock Incentive Plan. That cost is expected to be recognized over an estimated weighted-average amortization period of 3.27 years.

Short-term held-to-maturity investments primarily comprised of term deposits with maturities from the date of purchase greater than three months and less than one year. These term deposits are held until the maturity date and are not traded. Long-term available-for-sale securities primarily consist of investments in other companies’ equity securities and foreign government bonds purchased pursuant to local regulations, maturing in fiscal year 2023. Long-term held-to-maturity investments consist of term deposits with maturities not exceeding one year. These term deposits are renewed due to certain restrictions under the terms of an acquisition arrangement. Long-term cost-method investments consist primarily of investments in equity securities of private entities. Trading and available-for-sale securities are recorded at fair value in each reporting period and therefore the carrying value of these securities equals their fair value (See Note 9 The following table summarizes the total gains recorded in “Other income (expense), net” in the Consolidated Statements of Operations for changes in the fair value of the Company's trading investment: Fiscal Years Ended November 30, 2018 2017 2016 Gains on trading securities $ 2,423 $ — $ — Cash flows from purchases of available-for-sale and held-to-maturity securities are classified as cash flows from investing activities and reported gross on a combined basis as these principally represent cash flows from held-to-maturity securities.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments	NOTE 8—DERIVATIVE INSTRUMENTS: In the ordinary course of business, the Company is exposed to foreign currency risk, interest rate risk, equity risk, commodity price changes and credit risk. The Company enters into transactions, and owns monetary assets and liabilities, that are denominated in currencies other than the legal entity’s functional currency. The Company may enter into forward contracts, option contracts, swaps, or other derivative instruments to offset a portion of the risk on expected future cash flows, earnings, on net investments in certain foreign subsidiaries and on certain existing assets and liabilities. However, the Company may choose not to hedge certain exposures for a variety of reasons including, but not limited to, accounting considerations and the prohibitive economic cost of hedging particular exposures. There can be no assurance the hedges will offset more than a portion of the financial impact resulting from movements in foreign currency exchange or interest rates. Generally, the Company does not use derivative instruments to cover equity risk and credit risk. The Company’s hedging program is not used for trading or speculative purposes. All derivatives are recognized on the balance sheet at their fair value. Changes in the fair value of derivatives are recorded in the Consolidated Statements of Operations, or as a component of “AOCI” in the Consolidated Balance Sheets, as discussed below. Cash Flow Hedges To protect gross margins from fluctuations in foreign currency exchange rates, certain of the Company’s subsidiaries with functional currencies that are not the U.S. dollar may hedge a portion of forecasted revenue or costs not denominated in the subsidiaries’ functional currencies. These instruments mature at various dates through March 2021. The Company also uses interest rate derivative contracts to economically convert a portion of its variable-rate debt to fixed-rate debt. The swaps have maturities up to October 31, 2023. Gains and losses on cash flow hedges are recorded in AOCI until the hedged item is recognized in earnings. Deferred gains and losses associated with cash flow hedges of foreign currency revenue are recognized as a component of "Revenue from Services" in the same period as the related revenue is recognized, and deferred gains and losses related to cash flow hedges of costs are recognized as a component of "Cost of revenue" for "services" and/or "Selling, general and administrative expenses" in the same period as the related costs are recognized. Deferred gains and losses associated with cash flow hedges of interest expense are recognized in "Interest expense and Finance charges, net" in the same period as the related expense is recognized. Derivative instruments designated as cash flow hedges must be de-designated as hedges when it is probable the forecasted hedged transaction will not occur in the initially identified time period or within a subsequent two-month time period. Deferred gains and losses in AOCI associated with such derivative instruments are reclassified into earnings in the period of de-designation. Any subsequent changes in fair value of such derivative instruments are recorded in earnings unless they are re-designated as hedges of other transactions. Non-Designated Derivatives The Company uses short-term forward contracts to offset the foreign exchange risk on assets and liabilities denominated in currencies other than the functional currency of the respective entities. The contracts not designated as hedging instruments mature or settle in six months or less. Derivatives that are not designated as hedging instruments are adjusted to fair value through earnings in the financial statement line item to which the derivative relates. See Note 11--Borrowings, for the accounting for the embedded derivative in the 5.75% Junior Subordinated Convertible Debentures assumed by the Company’s subsidiary, Concentrix CVG Corporation, as part of the Convergys acquisition. Fair Values of Derivative Instruments in the Consolidated Balance Sheets The fair values of the Company’s derivative instruments are disclosed in Note 9 Value as of Balance Sheet Line Item November 30, 2018 November 30, 2017 Derivative instruments not designated as hedging instruments: Foreign exchange forward contracts (notional value) $ 1,008,895 $ 248,069 Other current assets 12,651 1,483 Other accrued liabilities 1,856 1,194 Other long-term liabilities — 1,372 Interest rate swap (notional value) $ 100,000 $ — Other assets 3,519 — Derivative instruments designated as cash flow hedges: Foreign exchange forward contracts (notional value) $ 624,014 $ — Other current assets 2,819 — Other assets 1,015 — Other accrued liabilities 9,632 — Other long-term liabilities 2,674 — Interest rate swaps (notional value) $ 1,900,000 $ 600,000 Other current assets 884 — Other assets 4,985 3,484 Other accrued liabilities — 389 Other long-term liabilities 9,004 1,996 Volume of activity The notional amounts represent the gross amounts of foreign currency, including, principally, the Philippine Peso, the Euro, Indian Rupee, British Pound, Canadian Dollar, Brazilian Real, Chinese Yuan, Colombian Peso and Australian Dollars that will be bought or sold at maturity. The notional amounts for outstanding derivative instruments provide one measure of the transaction volume outstanding and do not represent the amount of the Company’s exposure to credit or market loss. The Company’s exposure to credit loss and market risk will vary over time as currency and interest rates change. The Effect of Derivative Instruments in AOCI and the Consolidated Statement of Earnings The following table shows the gains and losses, before taxes, of the Company's derivative instruments designated as cash flow hedges and not designated as hedging instruments in Other Comprehensive Income, or OCI, and the Consolidated Statements of Operations: Location of Gain (Loss) in Income (1) Fiscal Years Ended November 30, 2018 2017 2016 Total "Cost of revenue" for "services" $ (1,514,470 ) $ (1,232,666 ) $ (963,393 ) Total "Selling, general and administrative expenses" (1,376,664 ) (1,041,975 ) (903,369 ) Total "Interest expense and finance charges, net" (84,675 ) (45,357 ) (28,993 ) Derivative Instruments designated as cash flow hedges: Gains (Losses) recognized in OCI: Foreign exchange contracts $ 27,426 $ — $ — Interest rate swaps (1,256 ) 5,957 (2,340 ) Total $ 26,170 $ 5,957 $ (2,340 ) Gains (Losses) reclassified from AOCI into income: Foreign exchange contracts Gain reclassified from AOCI into income Cost of revenue for services $ 1,021 $ — $ — Gain reclassified from AOCI into income Selling, general and administrative expenses 441 — — Interest rate swaps Gain (Loss) reclassified from AOCI into income Interest expense and finance charges, net 2,792 (1,762) (1,436) Total $ 4,254 $ (1,762 ) $ (1,436 ) Derivative Instruments not designated as hedging instruments: Gain (loss) recognized from Foreign exchange forward contracts, net Cost of revenue for services and Selling, general and administrative expenses $ 3,378 $ — $ — Loss recognized from Foreign exchange forward contracts, net Other income (expense), net (6,126 ) (2,217) (1,629) Loss recognized from Interest rate swaps, net Interest expense and Finance charges, net (318 ) — — Total $ (3,066 ) $ (2,217 ) $ (1,629 ) ( 1 ) The gains and losses largely offset the currency gains and losses that resulted from changes in the assets and liabilities denominated in nonfunctional currencies. There were no material gain or loss amounts excluded from the assessment of effectiveness. Existing net gains in AOCI that are expected to be reclassified into earnings in the normal course of business within the next twelve months are $17,468. Offsetting of Derivatives In the Consolidated Balance Sheets, the Company does not offset derivative assets against liabilities in master netting arrangements. If derivative exposures covered by a qualifying master netting agreement had been netted in the Consolidated Statement of Financial Position, the total derivative asset and liability positions would have been reduced by $6,850 each as of November 30, 2018 and $1,352 each as of November 30, 2017. Credit exposure for derivative financial instruments is limited to the amounts, if any, by which the counterparties’ obligations under the contracts exceed the Company’s obligations to the counterparties. The Company manages the potential risk of credit losses through careful evaluation of counterparty credit standing and selection of counterparties from a limited group of financial institutions.

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	The Company’s fair value measurements are classified and disclosed in one of the following three categories: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). The following table summarizes the valuation of the Company’s investments and financial instruments that are measured at fair value on a recurring basis: As of November 30, 2018 As of November 30, 2017 Fair value measurement category Fair value measurement category Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Assets: Cash equivalents $ 108,785 $ 108,785 $ — $ — $ 157,935 $ 157,935 $ — $ — Trading securities 2,581 2,581 — — — — — — Available-for-sale securities 4,015 4,015 — — 3,376 3,376 — — Forward foreign currency exchange contracts 16,485 — 16,485 — 1,483 — 1,483 — Interest rate swaps 9,388 — 9,388 — 3,484 — 3,484 — Liabilities: Forward foreign currency exchange contracts $ 14,162 $ — $ 14,162 $ — $ 2,566 $ — $ 2,566 $ — Interest rate swaps 9,004 — 9,004 — 2,385 — 2,385 — Convertible debentures conversion option 77,238 — — 77,238 — — — — The Company’s cash equivalents consist primarily of highly liquid investments in money market funds and term deposits with maturity periods of three months or less. The carrying values of cash equivalents approximate fair value since they are near their maturity. Investments in trading and available-for-sale securities consist of equity securities and are recorded at fair value based on quoted market prices. The fair values of forward exchange contracts are measured based on the foreign currency spot and forward rates quoted by the banks or foreign currency dealers. Fair values of long-term foreign currency exchange contract are measured using valuations based upon quoted prices for similar assets and liabilities in active markets and are valued by reference to similar financial instruments, adjusted for terms specific to the contracts. Fair values of interest rate swaps are measured using standard valuation models using inputs that are readily available in public markets, or can be derived from observable market transactions, including London Interbank Offered Rate (“LIBOR”) spot and forward rates. The effect of nonperformance risk on the fair value of derivative instruments was not material as of November 30, 2018 and 2017. In connection with the Convergys acquisition, the Company's subsidiary, Concentrix CVG Corporation ("Concentrix CVG"), assumed Convergys' 5.75% Junior Subordinated Convertible Debentures due September 2029 ("Convertible Debentures") and recorded the principal amount and conversion spread at fair value. See Note 11--Borrowings. The fair value of the Convertible Debentures conversion option was based on a probabilistic analysis using the Monte Carlo simulation approach. The model considered simulated movements in the Company's stock price until the conversion date using estimated stock volatility of 35%, a risk free rate of 2.7%, discount and dividend yields of 4.6% and $0.35 per share each quarter, respectively, over the estimated period until the Company would be entitled to redeem the debentures in September 2019. From the acquisition date until November 30, 2018, the fair value of the conversion spread decreased by $4,085 . The carrying values of held-to-maturity securities with maturities less than one year, accounts receivable, accounts payable and short-term debt approximate fair value due to their short maturities and interest rates which are variable in nature. The fair value of cost-method investments is based on an internal valuation of the investees based on the best available information at the measurement date. The carrying value of the Company’s term loans approximate their fair value since they bear interest rates that are similar to existing market rates. During fiscal years 2018, 2017 and 2016, there were no transfers between the fair value measurement category levels.

Transfers And Servicing [Abstract]
Accounts Receivable Arrangements	The Company has an uncommitted supply-chain financing program with a global financial institution under which trade accounts receivable of certain customers and their affiliates may be acquired, without recourse, by the financial institution. Available capacity under this program is dependent on the level of the Company's trade accounts receivable with these customers and the financial institution’s willingness to purchase such receivables. As of November 30, 2018 and 2017, accounts receivable sold to and held by the financial institution under this program were $33,677 and $49,826, respectively. Discount fees related to the sale of trade accounts receivable under this facility are included in “Interest expense and finance charges, net” in the Consolidated Statement of Operations. During the fiscal years ended November 30, 2018, 2017 and 2016, discount fees were $1,621, $1,201 and $968, respectively. SYNNEX Infotec, the Company's Japanese Technology Solutions subsidiary, has arrangements with financial institutions for the sale and financing of approved accounts receivable and notes receivable. The amounts outstanding under these arrangements that were sold, but not collected, as of November 30, 2018 and 2017 were $2,848 The Company also has other financing agreements in North America with various financial institutions (“Flooring Companies”) to allow certain customers of the Company to finance their purchases directly with the Flooring Companies. Under these agreements, the Flooring Companies pay to the Company the selling price of products sold to various customers, less a discount, within approximately 15 to 30 days from the date of sale. The Company is contingently liable to repurchase inventory sold under flooring agreements in the event of any default by its customers under the agreement and such inventory being repossessed by the Flooring Companies. Please see Note 17 — Commitments and Contingencies for further information. The following table summarizes the net sales financed through the flooring agreements and the flooring fees incurred: Fiscal Years Ended November 30, 2018 2017 2016 Net sales financed $ 1,734,860 $ 1,262,325 $ 1,264,117 Flooring fees ( 1) 10,698 8,192 8,240 (1) Flooring fees are included within “Interest expense and finance charges, net.” As of November 30, 2018 and 2017, accounts receivable subject to flooring agreements were $84,668

Income Taxes	The sources of income before the provision for income taxes and non-controlling interest are as follows: Fiscal Years Ended November 30, 2018 2017 2016 United States $ 194,402 $ 257,837 $ 185,936 Foreign 262,975 206,894 170,128 $ 457,377 $ 464,731 $ 356,064 Provision for income taxes consists of the following: Fiscal Years Ended November 30, 2018 2017 2016 Current tax provision: Federal $ 113,242 $ 105,879 $ 68,309 State 20,263 17,900 8,241 Foreign 70,162 65,000 51,918 $ 203,667 $ 188,779 $ 128,468 Deferred tax provision (benefit): Federal $ (30,414 ) $ (16,303 ) $ 3,383 State (4,863 ) (1,379 ) (1,608 ) Foreign (11,611 ) (7,539 ) (9,184 ) $ (46,888 ) $ (25,221 ) $ (7,409 ) Total tax provision $ 156,779 $ 163,558 $ 121,059 On December 22, 2017, Public Law 115-97, informally referred to as the Tax Cuts and Jobs Act (the “TCJA”) was enacted into law. The TCJA provides for significant changes to the U.S. Internal Revenue Code of 1986, as amended, that impact corporate taxation requirements. The TCJA significantly revises the ongoing U.S. corporate income tax law by lowering the U.S. federal corporate income tax rate from 35% to 21%, implementing a territorial tax system, imposing a one-time tax on foreign unremitted earnings and setting limitations on deductibility of certain costs (e.g., interest expense), among other things. Accounting for the impact of the TCJA resulted in an increase in income tax expense of $33,109. The significant components of this expense are (i) the one-time deemed repatriation tax on unremitted non-U.S. earnings and profits that were previously tax deferred and other tax impacts of the TCJA, which resulted in an increase in income tax expense, net of deductions and credits, of $59,823 and (ii) the remeasurement of net deferred tax liabilities at the lower enacted U.S. federal corporate tax rate, which resulted in a decrease of $26,714 in income tax expense. The Company measured the deemed repatriation tax in accordance with proposed regulations issued by the U.S Treasury Department on August 1, 2018. In January 2019, the U.S. Treasury Department issued the final regulations to be published in the Federal Register. The impact of the final regulations will be recorded upon becoming effective. The following presents the breakdown of net deferred tax liabilities: As of November 30, 2018 2017 Deferred tax assets $ 76,508 $ 31,687 Deferred tax liabilities (206,024 ) (113,527 ) Total net deferred tax liabilities $ (129,516 ) $ (81,840 ) Net deferred tax liabilities consist of the following: As of November 30, 2018 2017 Assets: Accruals and other reserves $ 73,263 $ 45,711 Net operating losses 71,899 14,537 Intercompany payables/receivables 39,476 — Allowance for doubtful accounts and sales return reserves 15,695 14,819 Foreign tax credit 15,456 — Share-based compensation expense 11,605 7,709 Tax credits 11,305 10,063 Inventory reserves 11,041 15,591 Deferred revenue 7,434 7,000 Others 16,524 13,630 Gross deferred tax assets 273,698 129,060 Valuation allowance (61,840 ) (18,604 ) Total deferred tax assets $ 211,858 $ 110,456 Liabilities: Intangible assets $ (310,092 ) $ (164,253 ) Unremitted non-US earnings (21,528 ) — Depreciation and amortization (1,669 ) (28,043 ) Others (8,084 ) — Total deferred tax liabilities $ (341,374 ) $ (192,296 ) Net deferred tax liabilities $ (129,516 ) $ (81,840 ) The valuation allowance relates primarily to certain state and foreign net operating loss carry forward, foreign deferred items and state credits. The Company’s assessment is that it is not more likely than not that these deferred tax assets will be realized. A reconciliation of the statutory United States federal income tax rate to the Company’s effective income tax rate is as follows: Fiscal Years Ended November 30, 2018 2017 2016 Federal statutory income tax rate 22.2 % 35.0 % 35.0 % State taxes, net of federal income tax benefit 2.4 2.9 2.3 Foreign taxes 0.6 (3.2 ) (4.7 ) Adjustments related to the TCJA 7.2 — — Other 1.9 0.5 1.4 Effective income tax rate 34.3 % 35.2 % 34.0 % The Company’s United States business has sufficient cash flow and liquidity to fund its operating requirements and the Company expects and intends that profits earned outside the United States will be fully utilized and reinvested outside of the United States with the exception for earnings of certain previously acquired foreign entities. The Company recorded deferred tax liabilities related to non-U.S. withholding taxes related to the earnings likely to be repatriated in the future. As of November 30, 2018, the Company had approximately $1,445,710 of undistributed earnings of its non-U.S. subsidiaries for which it has not provided for non-U.S. withholding taxes and state taxes because such earnings are intended to be reinvested indefinitely in international operations. It is not practicable to determine the amount of applicable taxes that would be due if such earnings were distributed. Accordingly, the Company has not provisioned United States state taxes and foreign withholding taxes on non-U.S. subsidiaries for which the earnings are permanently reinvested. As of November 30, 2018, the Company had net operating loss carry forward of approximately $22,640 and $60,824 for federal and state purposes, respectively. The federal net operating loss carry forward will start expiring in fiscal year ending November 30, 2021, if not used, and the state net operating loss carry forward will start expiring in fiscal year ending November 30, 2019, if not used. The Company also had approximately $129,361 of foreign net operating loss carry forward that will also start expiring in fiscal year ending November 30, 2019 if not used. In addition, the Company has approximately $20,972 of various federal and state income tax credit carry forwards that if not used, will begin expiring in fiscal year ending November 30, 2020. Utilization of the acquired loss carry forwards may be limited pursuant to Section 382 of the Internal Revenue Code of 1986. The Company enjoys tax holidays in certain jurisdictions, primarily, China, Costa Rica, Nicaragua, and the Philippines. The tax holidays provide for lower or zero rates of taxation and require various thresholds of investment and business activities in those jurisdictions. Certain tax holidays begin to expire in 2019. The estimated range of tax benefits from the above tax holidays on diluted earnings per share for fiscal years 2018, 2017, and 2016 were approximately $0.10 to $0.12, $0.07 to $0.08 and $0.07 to $0.08 respectively. The aggregate changes in the balances of gross unrecognized tax benefits, excluding accrued interest and penalties, during fiscal years 2018, 2017, and 2016 were as follows: Balance as of November 30, 2015 $ 22,815 Additions based on tax positions related to the current year 6,727 Additions for tax positions of prior years 5,613 Lapse of statute of limitations (2,241 ) Changes due to translation of foreign currencies (140 ) Balance as of November 30, 2016 32,774 Additions based on tax positions related to the current year 9,022 Additions for tax positions of prior years 231 Lapse of statute of limitations (2,300 ) Changes due to translation of foreign currencies 179 Balance as of November 30, 2017 38,282 Additions based on tax positions related to the current year 8,173 Additions for tax positions of prior years and acquisition 10,763 Lapse of statute of limitations (3,641 ) Changes due to translation of foreign currencies 398 Balance as of November 30, 2018 $ 53,975 The Company conducts business globally and files income tax returns in various U.S. and foreign tax jurisdictions. The Company is subject to continuous examination and audits by various tax authorities. Significant audits are underway in the Unites States, Canada and India. The Company is not aware of any material exposures arising from these tax audits or in other jurisdictions not already provided for. Although timing of the resolution of audits and/or appeals is highly uncertain, the Company believes it is reasonably possible that the total amount of unrecognized tax benefits as of November 30, 2018 will not materially change in the next twelve months. The Company is no longer subject to U.S. federal income tax audit for returns covering years through fiscal 2014. The Company is no longer subject to foreign or state income tax audits for returns covering years through 2003, and fiscal year 2002, respectively. As of November 30, 2018, $53,713 of the total unrecognized tax benefits, net of federal benefit, would affect the effective tax rate, if realized. The Company’s policy is to include interest and penalties related to income taxes, including unrecognized tax benefits, within the provision for income taxes. As of November 30, 2018 and 2017, the Company had accrued $13,003 and $5,867

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	The Company leases certain of its facilities under operating lease agreements, which expire in various periods through 2029. Future minimum contractually required cash payment obligations under non-cancellable lease agreements as of November 30, 2018 were as follows: Fiscal Years Ending November 30, 2019 $ 203,377 2020 167,833 2021 127,562 2022 94,691 2023 60,748 thereafter 90,511 Total minimum lease payments $ 744,722 Rent expense for the years ended November 30, 2018, 2017 and 2016 amounted to $136,870, $115,480 and $105,350, respectively. Sublease income was immaterial for each of the periods presented and is immaterial for the amounts entitled to be received in future periods under non-cancellable sublease arrangements. The Company was contingently liable as of November 30, 2018 under agreements to repurchase repossessed inventory acquired by flooring companies as a result of default on floor plan financing arrangements by the Company’s customers. These arrangements are described in Note 10 -- Accounts Receivable Arrangements, and do not have expiration dates. As the Company does not have access to information regarding the amount of inventory purchased from the Company still on hand with the customer at any point in time, the Company’s repurchase obligations relating to inventory cannot be reasonably estimated. Losses, if any, would be the difference between the repossession cost and the resale value of the inventory. There have been no From time to time, the Company receives notices from third parties, including customers and suppliers, seeking indemnification, payment of money or other actions in connection with claims made against them. Also, from time to time, the Company has been involved in various bankruptcy preference actions where the Company was a supplier to the companies now in bankruptcy. In addition, the Company is subject to various other claims, both asserted and unasserted, that arise in the ordinary course of business. The Company is currently not involved in any such proceedings that are material to the Company. The Company does not believe that the above commitments and contingencies will have a material adverse effect on the Company’s results of operations, financial position or cash flows.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Use of estimates	Use of estimates The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. The Company evaluates these estimates on a regular basis and bases them on historical experience and on various assumptions that the Company believes are reasonable. Actual results could differ from the estimates.
Principles of consolidation	Principles of consolidation The Consolidated Financial Statements include the accounts of the Company, its wholly-owned subsidiaries, majority-owned subsidiaries in which no substantive participating rights are held by minority stockholders and variable interest entities if the Company is the primary beneficiary. All intercompany accounts and transactions have been eliminated. The Consolidated Financial Statements include 100% of the assets and liabilities of majority-owned subsidiaries and the ownership interest of minority investors is recorded as noncontrolling interest. Investments in 20% through 50% owned affiliated companies are accounted under the equity method where the Company exercises significant influence over operating and financial affairs of the investee and is not the primary beneficiary. Investments in less than 20% owned companies are recorded as cost method investments, available for sale securities or trading securities, unless the Company has significant influence.
Segment reporting	Segment reporting Operating segments are based on components of the Company that engage in business activity that earns revenue and incurs expenses and (a) whose operating results are regularly reviewed by the Company’s chief operating decision maker to make decisions about resource allocation and performance and (b) for which discrete financial information is available. The Company has two reportable segments: Technology Solutions and Concentrix. The Technology Solutions segment represents an aggregation of the Technology Solutions United States, Canada, Japan and Latin America operating segments. The Technology Solutions segment distributes peripherals, IT systems, including data center servers, system components, software, networking, communications, security equipment, consumer electronics (“CE”) and complementary products to a variety of customers, including value-added resellers, system integrators and retailers. The segment also designs and integrates energy efficient data center servers built specific to the customers' data center environment. The Concentrix segment offers a range of technology-enabled global business outsourcing services focused on customer engagement, process optimization and front and back-office automation to clients in ten industry verticals. The portfolio of services offered comprises end-to-end process outsourcing services that are delivered through omni-channels including both voice and non-voice.
Cash and cash equivalents	Cash and cash equivalents The Company considers all highly liquid debt instruments purchased with an original maturity or remaining maturity at the date of purchase of three months or less to be cash equivalents. Cash equivalents consist principally of money market deposit accounts and money market funds
Allowance for doubtful accounts	Allowance for doubtful accounts The allowance for doubtful accounts is an estimate to cover the losses resulting from the inability of customers to make payments for outstanding balances. In estimating the required allowance, the Company takes into consideration the overall quality and aging of the accounts receivable, credit evaluations of customers’ financial condition and existence of credit insurance. The Company also evaluates the collectability of accounts receivable based on specific customer circumstances, current economic trends, historical experience with collections and any value and adequacy of collateral received from customers.
Inventories	Inventories Inventories are stated at the lower of cost and net realizable value. Cost is computed based on the weighted-average method. Inventories are comprised of finished goods and work-in-process. Finished goods include products purchased for resale, system components purchased for both resale and for use in the Company’s systems design and integration business, and completed systems. Work-in-process inventories are not material to the Consolidated Financial Statements.
Derivatives Financial Instruments	Derivative Financial Instruments The Company accounts for its derivative instruments as either assets or liabilities and carries them at fair value. For derivative instruments that hedge the exposure to variability in expected future cash flows that are designated as cash flow hedges, the gain or loss on the derivative instrument is reported as a component of “Accumulated other comprehensive income (loss),” in stockholders’ equity and reclassified into earnings in the same line associated with the forecasted transactions, in the same period or periods during which the hedged transaction affects earnings. To receive hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions. For derivative instruments that are not designated as hedges, gains and losses on derivative instruments are reported in the Consolidated Statements of Operations in the current period.
Property and equipment	Property and equipment Property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method based upon the shorter of the estimated useful lives of the assets, or the lease term of the respective assets, if applicable. Maintenance and repairs are charged to expense as incurred, and improvements are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation and amortization are removed from the accounts and any resulting gain or loss is reflected in operations in the period realized. The ranges of estimated useful lives for property and equipment categories are as follows: Equipment and Furniture 3 - 10 years Software 3 - 7 years Leasehold improvements 2 - 15 years Buildings and building improvements 10 - 40 years
Business Combinations	Business Combinations The purchase price is allocated to the assets acquired, liabilities assumed, and non-controlling interests in the acquired entity generally based on their fair values at the acquisition date. The excess of the fair value of purchase consideration over the fair value of these assets acquired, liabilities assumed and non-controlling interests in the acquired entity is recorded as goodwill. The primary items that generate goodwill include the value of the synergies between the acquired entity and the Company and the value of the acquired assembled workforce, neither of which qualify for recognition as an intangible asset. Amounts recorded in a business combination may change during the measurement period, which is a period not to exceed one year from the date of acquisition, as additional information about conditions existing at the acquisition date becomes available. The Company includes the results of operations of the acquired business in the Consolidated Financial Statements prospectively from the date of acquisition. Acquisition-related charges are recognized separately from the business combination and are expensed as incurred. These charges primarily include, direct third-party professional and legal fees, and integration-related costs.
Goodwill and intangible assets	Goodwill and intangible assets The values assigned to intangible assets are based on estimates and judgment regarding expectations for the success and life cycle of products and technologies and length of customer relationships acquired in a business combination. Purchased intangible assets are amortized over the useful lives based on estimates of the use of the economic benefit of the asset or on the straight-line amortization method. The Company allocates goodwill to reporting units based on the reporting unit expected to benefit from the business combination and tests for impairment annually in the fourth quarter or more frequently if events or changes in circumstances indicate that it may be impaired. Goodwill is tested for impairment at the reporting unit level by first performing a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying value. The factors that are considered in the qualitative analysis include macroeconomic conditions, industry and market considerations, cost factors such as increases in product cost, labor, or other costs that would have a negative effect on earnings and cash flows; and other relevant entity-specific events and information. If the reporting unit does not pass the qualitative assessment, then the reporting unit’s carrying value is compared to its fair value. The fair values of the reporting units are estimated using market and discounted cash flow approaches. The assumptions used in the market approach are based on the value of a business through an analysis of sales and other multiples of guideline companies and recent sales or offerings of a comparable entity. The assumptions used in the discounted cash flow approach are based on historical and forecasted revenue, operating costs, future economic conditions, and other relevant factors. Goodwill is considered impaired if the carrying value of the reporting unit exceeds its fair value and the excess is recognized as an impairment loss. No goodwill impairment has been identified for any of the years presented. Intangible assets consist primarily of customer relationships and lists, vendor lists, technology and trade names. Amortization is based on the pattern in which the economic benefits of the intangible assets will be consumed or on a straight line basis when the consumption pattern is not apparent over the following useful lives: Customer relationships and lists 4 - 15 years Vendor lists 10 years Technology 5 years Other intangible assets 1- 10 years
Impairment of long-lived assets	Impairment of long-lived assets The Company reviews the recoverability of its long-lived assets, such as intangible assets, property and equipment and certain other assets, when events or changes in circumstances occur that indicate the carrying value of the asset or asset group may not be recoverable. The assessment of possible impairment is based on the Company’s ability to recover the carrying value of the asset or asset group from the expected future pre-tax cash flows, undiscounted and without interest charges, of the related operations. If these cash flows are less than the carrying value of such assets, an impairment loss is recognized for the difference between estimated fair value and carrying value.
Concentration of credit risk	Concentration of credit risk Financial instruments that potentially subject the Company to significant concentration of credit risk consist principally of cash and cash equivalents, accounts receivable and derivative instruments. The Company’s cash and cash equivalents and derivative instruments are transacted and maintained with financial institutions with high credit standing, the compositions and maturities of which are regularly monitored by management. Through November 30, 2018, the Company has not experienced any credit losses on such deposits and derivative instruments. Accounts receivable include amounts due from customers and original equipment manufacturer (“OEM”) vendors primarily in the technology industry. The Company performs ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended when deemed necessary, but generally requires no collateral. The Company also maintains allowances for potential credit losses. In estimating the required allowances, the Company takes into consideration the overall quality and aging of the receivable portfolio, the existence of a limited amount of credit insurance and specifically identified customer and vendor risks. Through November 30, 2018, such losses have been within management’s expectations. In fiscal years 2018, 2017 and 2016, one customer accounted for 17%, 21% and 12%, respectively of the Company’s consolidated revenue. Products purchased from the Company’s largest OEM supplier, HP Inc., accounted for approximately 12%, 13% and 17% of the consolidated revenue for fiscal years 2018, 2017 and 2016, respectively. As of November 30, 2018, there was no customer which represented more than 10% of the total accounts receivable balance. As of November 30, 2017, one customer comprised 12% of the total accounts receivable balance.
Book overdrafts	Book overdrafts Book overdrafts, representing checks issued in excess of balances on deposit in the applicable bank accounts and which have not been paid by the applicable bank at the balance sheet date are classified as “Borrowings, current” in the Company’s Consolidated Balance Sheets. Under the terms of the Company’s banking arrangements, the respective financial institutions are not legally obligated to honor the book overdraft balances. The Company’s policy is to report the change in book overdrafts as a financing activity in the Consolidated Statements of Cash Flows.
Revenue recognition	Revenue recognition Products revenue represents revenue from the Company’s Technology Solutions segment and services revenue represents revenue from the Company’s Concentrix segment. Technology Solutions The Company generally recognizes revenue on the sale of hardware and software products when they are shipped or delivered and on services when they are performed, if persuasive evidence of an arrangement exists, the sales price is fixed or determinable, collection of resulting accounts receivable is reasonably assured, risk of loss and title have transferred and product returns are reasonably estimable. Binding purchase orders from customers together with agreement to the Company's terms and conditions of sale by way of an executed agreement or other signed document constitutes evidence of an arrangement. Where product acceptance provisions exist, assuming all other revenue recognition criteria are met, revenue is recognized upon the earlier of shipment/delivery for products that have been demonstrated to meet product specifications, customer acceptance or the lapse of acceptance provisions. Provisions for sales returns and allowances are estimated based on historical data and are recorded concurrently with the recognition of revenue. These provisions are reviewed and adjusted periodically by the Company. Revenue is presented net of taxes collected from customers and remitted to government authorities. Revenue is reduced for early payment discounts and volume incentive rebates offered to customers. The Company recognizes revenue on a net basis on certain contracts, including service contracts, post-contract software support services and extended warranty contracts, where it is not the primary obligor, by recognizing the margins earned in revenue with no associated cost of revenue. Concentrix The Company recognizes revenue from services contracts when evidence of an arrangement exists, services are delivered, fees are fixed or determinable and collectability is reasonably assured. Service contracts may be based on a fixed price or on a fixed unit-price per transaction or other objective measure of output. Revenue on fixed price contracts is recognized on a straight-line basis over the term of the contract as services are provided. Revenue on unit-price transactions is recognized using an objective measure of output including staffing hours or the number of transactions processed by service agents. Customer contract terms can range from less than one year to more than five years. Revenue is reported net of any revenue-based taxes assessed by governmental authorities that are imposed on and concurrent with specific revenue-producing transactions.
Cost of revenue	Cost of Revenue Cost of products revenue represents cost of the Company’s Technology Solutions segment and cost of services revenue represents cost of the Company’s Concentrix segment. Technology Solutions Cost of revenue includes the product price paid to OEM suppliers, net of any incentives, rebates, price protection and purchase discounts received from the OEM suppliers. Cost of revenue also consists of provisions for inventory losses and write-downs, shipping and handling costs and royalties due to OEM vendors. In addition, cost of revenue includes the cost of materials, labor and overhead and warranty for design and integration activities. Concentrix Recurring direct operating costs for services are recognized as incurred. Cost of services revenue consists primarily of personnel costs. Where a contract requires an up-front investment, which typically includes transition and set-up costs related to systems and processes, these amounts are deferred and amortized on a straight-line basis over the expected period of benefit, not to exceed the fixed term of the contract. The Company performs periodic reviews to assess the recoverability of deferred contract transition and setup costs. This review is done by comparing the estimated minimum remaining undiscounted cash flows of a contract to the unamortized contract costs. If such minimum undiscounted cash flows are not sufficient to recover the unamortized costs, an impairment loss is recognized for the difference between the estimated fair value and the carrying value. If a cash flow deficiency remains after reducing the carrying amount of the deferred costs, the Company evaluates any remaining long-lived assets related to that contract for impairment.
Selling, General and Administrative expenses	Selling, General and Administrative expenses Selling, general and administrative expenses are charged to income as incurred. Expenses of promoting and selling products and services are classified as selling expense and include such items as compensation, sales commissions and travel. General and administrative expenses include such items as compensation, cost of warehouse, delivery centers and other non-integration facilities, legal and professional costs, office supplies, non-income taxes, insurance and utility expenses. In addition, selling, general and administrative expenses include other operating items such as allowances for credit losses, depreciation and amortization of non-technology related intangible assets.
OEM supplier programs	OEM supplier programs Funds received from OEM suppliers for volume promotion programs, price protection and product rebates are recorded as adjustments to cost of revenue and/or the carrying value of inventories, as appropriate. Where there is a binding agreement, the Company tracks vendor promotional programs for volume discounts on a program-by-program basis and records them as a reduction to cost of revenue based on a systematic and rational allocation. The Company monitors the balances of vendor receivables on a quarterly basis and adjusts the balances due for differences between expected and actual sales volume. Vendor receivables are generally collected through reductions authorized by the vendor to accounts payable. Funds received for specific marketing and infrastructure reimbursements, net of related costs, are recorded as adjustments to “Selling, general and administrative expenses,” and any excess reimbursement amount is recorded as an adjustment to cost of revenue.
Royalties	Royalties The Company’s software product purchases include products licensed from OEM vendors, which are subsequently distributed to resellers. Royalties to OEM vendors are accrued and recorded in cost of revenue when software products are shipped and revenue is recognized.
Warranties	Warranties The Company’s OEM suppliers generally warrant the products distributed by the Company and allow returns of defective products. The Company generally does not independently warrant the products it distributes; however, the Company does warrant the following: (1) products that it builds to order from components purchased from other sources; and (2) its services with regard to products that it assembles for its customers. To date neither warranty expense, nor the accrual for warranty costs has been material to the Company’s Consolidated Financial Statements.
Advertising	Advertising Costs related to advertising and product promotion expenditures are charged to “Selling, general and administrative expenses” as incurred and are primarily offset by OEM marketing reimbursements. To date, net costs related to advertising and promotion expenditures have not been material.
Income taxes	Income taxes The asset and liability method is used in accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts in the financial statements using enacted tax rates and laws that will be in effect when the difference is expected to reverse. Tax on global low-taxed intangible income is accounted for as a current expense in the period in which the income is includable in a tax return using the “period cost” method. The Company recognizes tax benefits from uncertain tax positions only if that tax position is more likely than not to 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 positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. The Company recognizes interest and penalties related to unrecognized tax benefits in the provisions for income taxes.
Foreign currency translations	Foreign currency translations The financial statements of the Company’s foreign subsidiaries whose functional currencies are the local currencies are translated into U.S. dollars for consolidation as follows: assets and liabilities at the exchange rate as of the balance sheet date, stockholders’ equity at the historical rates of exchange, and income and expense amounts at the average exchange rate for the month. Translation adjustments resulting from the translation of the subsidiaries’ accounts are included in “Accumulated other comprehensive income (loss).” Transactions denominated in currencies other than the applicable functional currency are converted to the functional currency at the exchange rate on the transaction date. At period end, monetary assets and liabilities are remeasured to the functional currency using exchange rates in effect at the balance sheet date. Non-monetary assets and liabilities are remeasured at historical exchange rates. Gains and losses resulting from foreign currency transactions are included within “Other income (expense), net.”
Comprehensive income	Comprehensive income Comprehensive income is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. The primary components of comprehensive income for the Company include net income, foreign currency translation adjustments arising from the consolidation of the Company’s foreign subsidiaries, unrealized gains and losses on the Company’s available-for-sale securities, unrealized gains and losses on cash flow hedges and the changes in unrecognized pension and post-retirement benefits.
Share-based compensation	Share-based compensation The Company accounts for stock-based payment transactions in which the Company receives employee services in exchange for equity instruments of the Company. Stock-based compensation cost for stock options, restricted stock awards and units, performance restricted stock units and employee stock purchase plans is determined based on the fair value at the measurement date. The Company recognizes stock-based compensation cost as expense for awards other than its performance-based restricted stock units ratably on a straight-line basis over the requisite service period. The Company recognizes stock-based compensation cost associated with its performance based restricted stock units over the requisite service period if it is probable that the performance conditions will be satisfied. Effective fiscal year 2018, the Company accounts for expense reductions that result from the forfeiture of unvested awards in the period that the forfeitures occur. Prior to fiscal year 2018, the Company estimated forfeitures and only recorded compensation costs for those awards that were expected to vest.
Pension and post-retirement benefits	Pension and post-retirement benefits The funded status of the Company’s pension and other postretirement benefit plans is recognized in the Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of plan assets and the benefit obligation at November 30, the measurement date. For defined benefit pension plans, the benefit obligation is the projected benefit obligation ("PBO") and, for the other postretirement benefit plans, the benefit obligation is the accumulated postretirement benefit obligation ("APBO"). The PBO represents the actuarial present value of benefits expected to be paid upon retirement. For active plans, the present value reflects estimated future compensation levels. The APBO represents the actuarial present value of postretirement benefits attributed to employee services already rendered. The fair value of plan assets represents the current market value of assets held by an irrevocable trust fund for the sole benefit of participants. The measurement of the benefit obligation is based on the Company’s estimates and actuarial valuations. These valuations reflect the terms of the plans and use participant-specific information such as compensation, age and years of service, as well as certain key assumptions that require significant judgment, including, but not limited to, estimates of discount rates, expected return on plan assets, inflation, rate of compensation increases, interest crediting rates and mortality rates. The assumptions used are reviewed on an annual basis. The Company records pension expense related to multi-employer plans based on the amount of contributions that are contractually owed during the period based on the service provided by the employee.
Earnings per common share	Earnings per common share Earnings per share is calculated using the two-class method. The two-class method is an earnings allocation proportional to the respective ownership among holders of common stock and participating securities. Basic earnings per common share is computed by dividing net income attributable to the Company’s common stockholders by the weighted average of common shares outstanding during the period. Diluted earnings per common share also considers the dilutive effect of in-the-money stock options and restricted stock units, calculated using the treasury stock method.
Treasury Stock	Treasury Stock Repurchases of shares of common stock are accounted for at cost, which includes brokerage fees, and are included as a component of stockholders’ equity in the Consolidated Balance Sheets.
Recently adopted and issued accounting pronouncements	Recently adopted accounting pronouncements In August 2018, the Financial Accounting Standard Board (the “FASB”) issued guidance clarifying the accounting for capitalizing implementation costs incurred by a customer in a cloud computing arrangement that is a service contract. Under the new guidance, implementation costs related to a cloud computing arrangement will be deferred or expensed as incurred, in accordance with the existing guidance for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The amendments also require the customer to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement, which includes reasonably certain renewals. The guidance is effective for interim and annual reporting periods beginning after December 15, 2019 and early adoption is permitted. The Company adopted this guidance prospectively in the third quarter of fiscal year 2018. The adoption did not have a material impact on the Company's Consolidated Financial Statements. In March 2016, the FASB, issued guidance which changes the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification in the Consolidated Statement of Cash Flows. The guidance is effective for interim and annual periods beginning after December 15, 2016 and early adoption is permitted. The Company adopted this guidance prospectively, during the first quarter of fiscal year 2018. The adoption did not have a material impact on the Company's Consolidated Financial Statements. Recently issued accounting pronouncements In August 2018, the FASB issued new guidance to add, remove, and clarify disclosure requirements related to defined benefit pension and other postretirement plans. The amendment requires the Company to disclose the weighted-average interest crediting rates used in cash balance pension plans. It also requires the Company to disclose the reasons for significant changes in the benefit obligation or plan assets including significant gains and losses affecting the benefit obligation for the period. This standard is effective for fiscal years ending after December 15, 2020 and early adoption is permitted. The adoption is not expected to have a material impact on the Company's Consolidated Financial Statements. In August 2018, the FASB issued guidance to improve the effectiveness of fair value measurement disclosures by removing or modifying certain disclosure requirements and adding other requirements. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. Certain amendments should be applied prospectively, while all other amendments should be applied retrospectively to all periods presented. The Company is currently evaluating the impact of the new guidance. In February 2018, the FASB issued guidance that permits the Company to reclassify disproportionate tax effects in accumulated other comprehensive income caused by the Tax Cuts and Jobs Act of 2017 to retained earnings. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact of the new guidance. In June 2016, the FASB issued a new credit loss standard that replaces the incurred loss impairment methodology in current GAAP. The new impairment model requires immediate recognition of estimated credit losses expected to occur for most financial assets and certain other instruments. It is effective for annual reporting periods beginning after December 15, 2019 and interim periods within those annual periods. Early adoption for fiscal years beginning after December 15, 2018 is permitted. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first effective reporting period. The Company is currently evaluating the impact of the new guidance. In February 2016, the FASB issued a new standard which revises various aspects of accounting for leases. The most significant impact to the Company’s Consolidated Financial Statements relates to the recognition by a lessee of a right-of-use asset and a lease liability for virtually all of its leases other than short-term leases. The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment, such as for initial direct costs. Consistent with current guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification. For income statement purposes, operating leases will result in a straight line expense while finance leases will result in a front-loaded expense pattern. This accounting standard will be applicable to the Company at the beginning of its first quarter of fiscal year 2020 using a modified retrospective approach and early adoption is permitted. The Company expects that most of its operating lease commitments will be subject to the new standard and be recognized as operating lease liabilities and right-of-use assets upon adoption. The Company is currently evaluating the impact of the adoption of this new standard on its Consolidated Financial Statements. In January 2016, the FASB issued new guidance which amends various aspects of the recognition, measurement, presentation, and disclosure of financial instruments. With respect to the Company’s consolidated financial statements, the most significant impact relates to the accounting for equity investments (other than those that are consolidated or accounted under the equity method) which will be measured at fair value through earnings. The new guidance is effective for annual reporting periods, and interim periods within those years beginning after December 15, 2017, with early adoption permitted only for certain provisions. The amendments should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, with other amendments related specifically to equity securities without readily determinable fair values applied prospectively. The adoption is not expected to have a material impact on the Company's Consolidated Financial Statements. In May 2014, the FASB issued a comprehensive new revenue recognition standard for contracts with customers that will supersede most current revenue recognition guidance. The core principle of this standard is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Other major provisions include the capitalization and amortization of certain contract costs, ensuring the time value of money is considered in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. This guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts with customers. The guidance is applicable for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early application for fiscal years, and interim periods within those years, beginning after December 15, 2016 permitted. The standard permits the use of either the retrospective or cumulative effect transition method. This accounting standard is applicable to the Company at the beginning of the first quarter of fiscal year 2019 and will be adopted on a full retrospective basis. The Company is currently in the process of finalizing the impact of the adoption, including evaluating and assessing the impact on historical periods, and implementing the appropriate changes to its business processes, systems, and controls to support revenue recognition. The guidance is expected to change the recording of revenue to net presentation on certain Technology Solutions customer transactions. This change in presentation will result in a reduction in revenue, estimated to be up to 4% of previously reported revenue.
