Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation and Recently Issued Accounting Standards	1. Basis of Presentation and Rece ntly Issued Accounting Standards We empower organizations of all sizes with Insight Intelligent Technology Solutions TM Operating Segment Geography North America United States and Canada EMEA Europe, Middle East and Africa APAC Asia-Pacific Our offerings in North America and certain countries in EMEA and APAC include hardware, software and services. Our offerings in the remainder of our EMEA and APAC segments consist of largely software and certain software-related services. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly our financial position as of September 30, 2019 and our results of operations for the three and nine months ended September 30, 2019 and 2018 and cash flows for the nine months ended September 30, 2019 and 2018. The consolidated balance sheet as of December 31, 2018 was derived from the audited consolidated balance sheet at such date. The accompanying unaudited consolidated financial statements and notes have been prepared in accordance with the rules and regulations promulgated by the SEC and consequently do not include all of the disclosures normally required by United States generally accepted accounting principles (“GAAP”). The results of operations for interim periods are not necessarily indicative of results for the full year, due in part to the seasonal nature of our business. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the related notes thereto, in our Annual Report on Form 10-K for the year ended December 31, 2018. Our results of operations include the results of PCM, Inc. (“PCM”) from its acquisition date of August 30, 2019 and Cardinal Solutions Group, Inc. (“Cardinal”) from its acquisition date of August 1, 2018. The consolidated financial statements include the accounts of Insight Enterprises, Inc. and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The preparation of consolidated financial statements in conformity with GAAP 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 consolidated financial statements. Additionally, these estimates and assumptions affect the reported amounts of net sales and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, we evaluate our estimates, including those related to sales recognition, anticipated achievement levels under partner funding programs, assumptions related to stock-based compensation valuation, allowances for doubtful accounts, valuation of inventories, litigation-related obligations, valuation allowances for deferred tax assets and impairment of long-lived assets, including purchased intangibles and goodwill, if indicators of potential impairment exist. Recently Issued Accounting Standards In June 2016, the Financial Accounting Standards Board’s (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-13, “Financial Instruments – Credit Losses.” The new standard is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held at each reporting date. The new standard is effective for interim and annual periods beginning after December 15, 2019, and early adoption is permitted. We will adopt the new standard as of January 1, 2020 and do not expect the adoption to have a material effect on our consolidated financial statements. In April 2019, the FASB issued ASU No. 2019-04, “Codification Improvements to Topic 326, Financial Instruments – Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments.” The new standard provides changes for how a company considers expected recoveries and contractual extensions or renewal options when estimating expected credit losses. The new standard is effective with the adoption of ASU No. 2016-13. We will adopt the new standard as of January 1, 2020 and do not expect the adoption to have a material effect on our consolidated financial statements. Effective January 1, 2019, we adopted the FASB ASU No. 2016-02— Leases (Topic 842) Adoption of the new standard resulted in the recording of additional net operating lease ROU assets and lease liabilities of $65,922,000 and $70,512,000, respectively, as of January 1, 2019. The difference between the additional lease assets and lease liabilities reflected existing accrued and prepaid rent balances that were reclassified to the operating lease ROU asset at January 1, 2019. The standard did not materially impact our consolidated net earnings and had no impact on cash flows. There have been no other material changes in or additions to the recently issued accounting standards as previously reported in Note 1 to our Consolidated Financial Statements in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2018 that affect or may affect our current financial statements.

Leases

Leases	9 Months Ended
	Sep. 30, 2019
Leases [Abstract]
Leases	2. Leases We lease office space, distribution centers, land, vehicles and equipment. Lease agreements with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. Certain lease agreements include one or more options to renew, with renewal terms that can extend the lease term from one to five years The exercise of lease renewal options is at our sole discretion. Certain of our lease agreements include rental payments adjus ted periodically for inflation. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. Significant Leases Accounting Policy We determine if a contract or arrangement is, or contains, a lease at inception. Balances related to operating leases are included in other assets, other current liabilities, and other liabilities in our consolidated balance sheet. Balances related to financing leases are included in property and equipment, current portion of long-term debt, and long-term debt in our consolidated balance sheet. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The operating lease ROU asset includes any prepaid lease payments and additional direct costs and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. The following table provides information about the financial statement classification of our lease balances reported within the consolidated balance sheets as of September 30, 2019 and January 1, 2019 (in thousands): Leases Classification September 30, 2019 January 1, 2019 Assets Operating lease assets Other assets $ 78,621 $ 65,922 Finance lease assets Property and equipment (a) 1,178 1,693 Total lease assets $ 79,799 $ 67,615 Liabilities Current Operating lease liabilities Accrued expenses and other current liabilities $ 19,502 $ 15,788 Finance lease liabilities Current portion of long-term debt 1,143 1,399 Non-current Operating lease liabilities Other liabilities 64,018 54,724 Finance lease liabilities Long-term debt 670 1,521 Total lease liabilities $ 85,333 $ 73,432 (a) Recorded net of accumulated amortization of $515,000 as of September 30, 2019 and there is no accumulated amortization as of January 1, 2019.

Earnings Per Share [Abstract]
Net Earnings Per Share ("EPS")	4 . Net Earnings Per Share (“EPS”) Basic EPS is computed by dividing net earnings available to common stockholders by the weighted average number of common shares outstanding during each period. Diluted EPS is computed on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding restricted stock units (“RSUs”). A reconciliation of the denominators of the basic and diluted EPS calculations follows (in thousands, except per share data): Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Numerator: Net earnings $ 27,132 $ 32,154 $ 116,457 $ 116,636 Denominator: Weighted average shares used to compute basic EPS 35,512 35,468 35,631 35,622 Dilutive potential common shares due to dilutive RSUs, net of tax effect 356 489 396 390 Weighted average shares used to compute diluted EPS 35,868 35,957 36,027 36,012 Net earnings per share: Basic $ 0.76 $ 0.91 $ 3.27 $ 3.27 Diluted $ 0.76 $ 0.89 $ 3.23 $ 3.24 For the three and nine months ended September 30, 2019, 3,000 and 56,000, respectively, of our RSUs were not included in the diluted EPS calculations because their inclusion would have been anti-dilutive. These share-based awards could be dilutive in the future. There were 5,000 and 13,000 anti-dilutive RSUs for the three and nine months ended September 30, 2018, respectively.

While the ABL facility has a stated maximum amount, the actual availability under the ABL facility is limited by specified percentages of eligible accounts receivable and certain eligible inventory , in each case as set forth in the credit agreement . From time to time and at our option, we may request to increase the aggregate amount available for borrowing under the ABL facility by up to an aggregate of the U.S. dollar equivalent of $ 500,000,000 , subject to customary conditions , including receipt of commitments from lenders . The ABL facility is guaranteed by certain of our material subsidiaries and is secured by a lien on certain of our assets and certain of each other borrower’s and each guarantor’s assets. The interest rates applicable to borrowings under the ABL facility are based on the average aggregate excess availability under the ABL facility as set forth on a pricing grid in the credit agreement. The ABL facility matures on August 30, 2024 . As of September 30, 2019, eligible accounts receivable and inventory were sufficient to permit access to the full $ 1,200,000,000 facility amount, of which $ was outstanding. The ABL facility contains customary affirmative and negative covenants and events of default. If a default occurs (subject to customary grace periods and materiality thresholds) under the credit agreement, certain actions may be taken, including, but not limited to, possible termination of commitments and required payment of all outstanding principal amounts plus accrued interest and fees payable under the credit agreement. On August 30, 2019, we repaid in full and terminated our then existing senior revolving credit facility (the “revolving facility”). The revolving facility had an aggregate U.S. dollar equivalent maximum borrowing amount of $350,000,000, including a maximum borrowing capacity that could be used for borrowing in certain foreign currencies of $50,000,000. On August 30, 2019, we repaid in full and terminated our accounts receivable securitization financing facility (the “ABS facility”). The ABS facility had a maximum aggregate borrowing availability of $250,000,000, subject to limitations based on the quantity and quality of the underlying accounts receivable. Convertible Senior Notes due 2025 On August 15, 2019, we issued $300,000,000 aggregate principal amount of convertible senior notes (the “notes”) that mature on February 15, 2025. On August 23, 2019, we issued an additional $50,000,000 aggregate principal amount of the notes pursuant to the exercise in full by the initial purchasers of the notes of their option to purchase additional notes. The notes bear interest at an annual rate of 0.75% payable semiannually, in arrears, on February 15 th th Holders of the notes may convert their notes at their option at any time prior to the close of business on the business day immediately preceding June 15, 2024, under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on December 31, 2019 (and only during such calendar quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price of our common stock per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; (3) if we call any or all of the notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events. On or after June 15, 2024 until the close of business on the second scheduled trading day immediately preceding the maturity date, the holders may convert their notes at any time, regardless of the foregoing circumstances. Upon conversion, we will pay or deliver cash, shares of our common stock or a combination of the two, at our discretion. The conversion rate will initially be 14.6376 shares of common stock per $1,000 principal amount of notes (equivalent to an initial conversion price of approximately $68.32 per share of common stock). The conversion rate is subject to change in certain circumstances and will not be adjusted for any accrued and unpaid interest. In addition, following certain events that occur prior to the maturity date or following our issuance of a notice of redemption, the conversion rate is subject to an increase for a holder who elects to convert their notes in connection with those events or during the related redemption period in certain circumstances. If we undergo a fundamental change, the holders may require us to repurchase for cash all or any portion of their notes at a fundamental change repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. As of September 30, 2019, none of the criteria for a fundamental change or a conversion rate adjustment had been met. The maximum number of shares issuable upon conversion, including the effect of a fundamental change and subject to other conversion rate adjustments, would be 6,788,208. We may redeem for cash all or any portion of the notes, at our option, on or after August 20, 2022 if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the notes. The notes are subject to certain customary events of default and acceleration clauses. As of September 30, 2019, no such events have occurred. The notes consist of the following balances reported within the consolidated balance sheet as of September 30, 2019 (in thousands): Liability: Principal $ 350,000 Less: debt discount and issuance costs, net of accumulated accretion (67,957 ) Net carrying amount $ 282,043 Equity, net of deferred tax $ 44,731 The remaining life of the debt discount and issuance cost accretion is approximately 5.375 years. The effective interest rate on the liability component of the notes is 4.325%. The following table summarizes the equity components of the notes included in additional paid-in capital reported within the consolidated balance sheet as of September 30, 2019 (in thousands): Embedded Conversion Option Embedded Conversion Option - Debt Issuance Costs Deferred Tax Total Convertible Senior Notes due 2025 $ 61,250 $ (1,700 ) $ (14,819 ) $ 44,731 The following table summarizes the interest expense components resulting from the notes reported within the consolidated statement of operations for the three and nine months ended September 30, 2019 (in thousands): Interest expense Three months ended September 30, 2019 Nine months ended September 30, 2019 Contractual coupon interest $ 328 $ 328 Amortization of debt discount $ 1,235 $ 1,235 Amortization of debt issuance costs $ 163 $ 163 Convertible Note Hedge and Warrant Transaction In connection with the issuance of the notes, we entered into certain convertible note hedge and warrant transactions (the “Call Spread Transactions”) with respect to the Company’s common stock. The convertible note hedge consists of an option to purchase up to 5,123,160 common stock shares at a price of $68.32 per share. The hedge expires on February 15, 2025 and can only be concurrently executed upon the conversion of the notes. We paid approximately $66,325,000 for the convertible note hedge transaction. Additionally, we sold warrants to purchase 5,123,160 shares of common stock at a price of $103.12 per share. The warrants expire on May 15, 2025 and can only be exercised at maturity. The Company received aggregate proceeds of approximately $34,440,000 for the sale of the warrants. The Call Spread Transactions have no effect on the terms of the notes and reduce potential dilution by effectively increasing the initial conversion price of the notes to $103.12 per share of the Company’s common stock. Inventory Financing Facilities On July 10, 2019, we entered into an unsecured inventory financing facility with a maximum availability for vendor purchases of $200,000,000 with MUFG Bank Ltd (“MUFG”). Finance Lease and Other Financing Our finance lease obligations total ed $1,813,000 and $2,920,000 The current and long-term portions of our finance leases are included in the current and long-term portions of long-term debt in the table above and in our consolidated balance sheets as of September 30, 2019 and December 31, 2018.

Income Taxes	8 . Income Taxes Our effective tax rate for the three and nine months ended September 30, 2019 was 27.2% and 25.4%, respectively. For the three months ended September 30, 2019, our effective tax rate was higher than the United States federal statutory rate of 21.0% due primarily to state income taxes, net of federal benefit, higher taxes on earnings in foreign jurisdictions, and the effect of non-deductible acquisition-related expenses partially offset by the recognition of tax benefits related to research and development activities. For the nine months ended September 30, 2019, our effective tax rate was higher than the United States federal statutory rate of 21.0% due primarily to state income taxes, net of federal benefit, higher taxes on earnings in foreign jurisdictions, and the effect of non-deductible acquisition-related expenses partially offset by tax benefits on the settlement of employee share-based awards and the recognition of tax benefits related to research and development activities. Our effective tax rate for the three and nine months ended September 30, 2018 was 25.6% and 25.8%, respectively. For the three and nine months ended September 30, 2018, our effective tax rate was higher than the United States federal statutory rate of 21.0% due primarily to state income taxes, net of federal benefit. As of September 30, 2019 and December 31, 2018, we had approximately $8,666,000 and $6,849,000, respectively, of unrecognized tax benefits. Of these amounts, approximately $417,000 and $313,000, respectively, related to accrued interest. In the future, if recognized, the liability associated with uncertain tax positions would affect our effective tax rate. We do not believe there will be any changes over the next 12 months that would have a material effect on our effective tax rate. Several of our subsidiaries are currently under audit for tax years 2012 through 2017. Although the timing of the resolutions and/or closures of audits is highly uncertain, it is reasonably possible that the examination phase of these audits may be concluded within the next 12 months, which could increase or decrease the balance of our gross unrecognized tax benefits. However, based on the status of the various examinations in multiple jurisdictions, an estimate of the range of reasonably possible outcomes cannot be made at this time, but the estimated effect on our income tax expense and net earnings is not expected to be significant.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	10 . Commitments and Contingencies Contractual In the ordinary course of business, we issue performance bonds to secure our performance under certain contracts or state tax requirements. As of September 30, 2019, we had approximately $3,739,000 of performance bonds outstanding. These bonds are issued on our behalf by a surety company on an unsecured basis; however, if the surety company is ever required to pay out under the bonds, we have contractually agreed to reimburse the surety company. Management believes that payments, if any, related to these performance bonds are not probable at September 30, 2019. Accordingly, we have not accrued any liabilities related to such performance bonds in our consolidated financial statements. Employment Contracts and Severance Plans We have employment contracts with, and severance plans covering, certain officers and management teammates under which severance payments would become payable in the event of specified terminations without cause or terminations under certain circumstances after a change in control. In addition, vesting of outstanding nonvested RSUs would accelerate following a change in control. If severance payments under the current employment agreements or plan payments were to become payable, the severance payments would generally range from three to twenty-four months of salary. Indemnifications From time to time, in the ordinary course of business, we enter into contractual arrangements under which we agree to indemnify either our clients or third-party service providers from certain losses incurred relating to services performed on our behalf or for losses arising from defined events, which may include litigation or claims relating to past performance. These arrangements include, but are not limited to, the indemnification of our clients for certain claims arising out of our performance under our sales contracts, the indemnification of our landlords for certain claims arising from our use of leased facilities and the indemnification of the lenders that provide our credit facilities for certain claims arising from their extension of credit to us. Such indemnification obligations may not be subject to maximum loss clauses. Management believes that payments, if any, related to these indemnifications are not probable at September 30, 2019. Accordingly, we have not accrued any liabilities related to such indemnifications in our consolidated financial statements. We have entered into separate indemnification agreements with certain of our executive officers and with each of our directors. These agreements require us, among other requirements, to indemnify such officers and directors against expenses (including attorneys’ fees), judgments and settlements incurred by such individual in connection with any action arising out of such individual’s status or service as our executive officer or director (subject to exceptions such as where the individual failed to act in good faith or in a manner the individual reasonably believed to be in , or not opposed to , the best interests of the Company) and to advance expenses incurred by such individual with respect to which such individual may be entitled to indemnification by us. There are no pending legal proceedings that involve the indemnification of any of the Company’s directors or officers. Contingencies Related to Third-Party Review From time to time, we are subject to potential claims and assessments from third parties. We are also subject to various governmental, client and partner audits. We continually assess whether or not such claims have merit and warrant accrual. Where appropriate, we accrue estimates of anticipated liabilities in the consolidated financial statements. Such estimates are subject to change and may affect our results of operations and our cash flows. Legal Proceedings From time to time, we are party to various legal proceedings incidental to the business, including preference payment claims asserted in client bankruptcy proceedings, indemnification claims, claims of alleged infringement of patents, trademarks, copyrights and other intellectual property rights, employment claims, claims of alleged non-compliance with contract provisions, and claims related to alleged violations of laws and regulations. We regularly evaluate the status of the legal proceedings in which we are involved to assess whether a loss is probable or there is a reasonable possibility that a loss, or an additional loss, may have been incurred and determine if accruals are appropriate. If accruals are not appropriate, we further evaluate each legal proceeding to assess whether an estimate of possible loss or range of possible loss can be made. Although litigation is inherently unpredictable, we believe that we have adequate provisions for any probable and estimable losses. It is possible, nevertheless, that our consolidated financial position, results of operations or liquidity could be materially and adversely affected in any particular period by the work required pursuant to any legal proceedings or the resolution of any legal proceedings during such period. Legal expenses related to the defense of any legal proceeding or the negotiations, settlement, rulings and advice of outside legal counsel in connection with any legal proceeding are expensed as incurred. In connection with the acquisition of PCM, the Company has effectively assumed responsibility for PCM litigation matters, including various disputes related to PCM’s acquisition of certain assets of En Pointe Technologies in 2015. The seller of En Pointe Technologies and related entities providing various post-closing support functions to PCM have asserted claims regarding the sufficiency of earnout payments paid by PCM under the asset purchase agreement and the unwinding of the support functions post-closing. PCM has rejected and vigorously responded to those claims and is pursuing various counterclaims. The disputes are being heard by multiple courts and arbitrators in several different jurisdictions including California, Delaware and Pakistan. The Company cannot determine with certainty the costs or outcome of these matters. However, the Company is not involved in any pending or threatened legal proceedings, including the PCM litigation matters, that it believes would reasonably be expected to have a material adverse effect on its business, financial condition or results of operations.

Segment Reporting [Abstract]
Segment Information	11. Segment Information We operate in three reportable geographic operating segments: North America; EMEA; and APAC with PCM being included in our North America and EMEA segments. Our offerings in North America and certain countries in EMEA and APAC include IT hardware, software and services. Our offerings in the remainder of our EMEA and APAC segments are largely software and certain software-related services. The following table summarizes net sales by offering for North America, EMEA and APAC for the three and nine months ended September 30, 2019 and 2018 (in thousands): North America EMEA APAC Three Months Ended September 30, Three Months Ended September 30, Three Months Ended September 30, Sales Mix 2019 2018 2019 2018 2019 2018 Hardware $ 1,020,083 $ 953,431 $ 137,416 $ 147,497 $ 9,243 $ 6,041 Software 295,730 259,602 186,839 168,603 19,569 13,099 Services 199,349 158,426 31,453 29,080 12,865 11,947 $ 1,515,162 $ 1,371,459 $ 355,708 $ 345,180 $ 41,677 $ 31,087 North America EMEA APAC Nine Months Ended September 30, Nine Months Ended September 30, Nine Months Ended September 30, Sales Mix 2019 2018 2019 2018 2019 2018 Hardware $ 2,704,212 $ 2,724,916 $ 451,892 $ 505,844 $ 25,740 $ 22,518 Software 907,683 828,231 560,073 551,920 80,287 91,459 Services 551,215 465,458 113,092 104,086 39,840 36,658 $ 4,163,110 $ 4,018,605 $ 1,125,057 $ 1,161,850 $ 145,867 $ 150,635 All significant intercompany transactions are eliminated upon consolidation, and there are no differences between the accounting policies used to measure profit and loss for our segments or on a consolidated basis. Net sales are defined as net sales to external clients. None of our clients exceeded ten percent of consolidated net sales for the three or nine months ended September 30, 2019 or 2018. A portion of our operating segments’ selling and administrative expenses arise from shared services and infrastructure that we have historically provided to them in order to realize economies of scale and to use resources efficiently. These expenses, collectively identified as corporate charges, include senior management expenses, internal audit, legal, tax, insurance services, treasury and other corporate infrastructure expenses. Charges are allocated to our operating segments, and the allocations have been determined on a basis that we consider to be a reasonable reflection of the utilization of services provided to or benefits received by the operating segments.

Business Combinations [Abstract]
Acquisitions	12. PCM On August 30,2019, we completed our acquisition of PCM, acquiring 100 percent of the issued and outstanding shares of PCM for a cash purchase price of $745,562,000, which included cash and cash equivalents acquired of $84,637,000 and the payment of PCM’s outstanding debt. PCM is a provider of multi-vendor technology offerings, including hardware, software and services to small, mid-sized and corporate/enterprise commercial clients, state, local and federal governments and educational institutions across the United States, Canada and the United Kingdom. Based in El Segundo, California, PCM has 40 office locations globally and more than 4,000 teammates. We believe that this acquisition allows us to help existing PCM clients in positioning their businesses for future growth, transforming and securing their data platforms, creating modern and mobile experiences for their workforce and optimizing the procurement of technology. The addition of PCM complements our supply chain optimization solution offering, adding scale and clients in the mid-market and corporate space in North America. The following table summarizes the purchase price and the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition (in thousands): Purchase price net of cash and cash equivalents acquired $ 660,925 Fair value of net assets acquired: Current assets $ 542,642 Identifiable intangible assets - see description below 251,400 Property and equipment 96,959 Other assets 32,373 Current liabilities (367,613 ) Long-term liabilities, including deferred taxes (86,996 ) Total fair value of net assets acquired 468,765 Excess purchase price over fair value of net assets acquired ("goodwill") $ 192,160 Under the acquisition method of accounting, the total purchase price as shown in the table above was allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values. The excess of the purchase price over fair value of net assets acquired was recorded as goodwill. The estimated fair values of current assets and liabilities (other than deferred revenue and related deferred costs) are based upon their historical costs on the date of acquisition due to their short-term nature. The estimated fair values of the majority of property and equipment are also based upon historical costs as they approximate fair value. Certain long-term assets, including PCM’s IT systems, will be written down to the estimated fair value based on the economic benefit expected to be realized from the assets following the acquisition. The preliminary estimated fair value of identified intangible assets of $251,400,000 consists primarily of customer relationships, trade names and non-compete agreements, which are valued at $238,900,000, $8,400,000 and $4,100,000, respectively. These estimated values will be determined using the multiple-period excess earnings method, the relief from royalty method and the lost income method, respectively. The identifiable intangible assets resulting from the acquisition has been amortized using the straight-line method over the following estimated useful lives: customer relationships – 12-15 years; trade names – 1 year; non-compete agreements – 2-3 years. Amortization expense recognized relating to the acquired identifiable intangible assets for the period from the acquisition date through September 30, 2019 was $2,130,000. Goodwill of $192,160,000, which was recorded in our North America and EMEA operating segments, represents the excess of the purchase price over the estimated fair value assigned to tangible and identifiable intangible assets acquired and liabilities assumed from PCM. The goodwill is not amortized and will be tested for impairment annually in the fourth quarter of our fiscal year. The addition of the PCM technical employees to our team and the opportunity to grow our business are the primary factors making up the goodwill recognized as part of the transaction. None of the goodwill is tax deductible. The purchase price allocation is preliminary and was allocated using information currently available. Further information may lead to an adjustment of the purchase price allocation. We have consolidated the results of operations for PCM since its acquisition on August 30, 2019. Consolidated net sales and gross profit for the three and nine months ended September 30, 2019 each include $172,468,000 and $27,753,000, respectively, from PCM. The following table reports pro forma information as if the acquisition of PCM had been completed at the beginning of the earliest period presented (in thousands, except per share amounts): Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Net sales As reported $ 1,912,547 $ 1,747,726 $ 5,434,034 $ 5,331,090 Pro forma $ 2,322,828 $ 2,257,769 $ 6,910,356 $ 6,928,539 Net earnings As reported $ 27,132 $ 32,154 $ 116,457 $ 116,636 Pro forma $ 24,678 $ 31,876 $ 115,321 $ 114,250 Diluted earnings per share As reported $ 0.76 $ 0.89 $ 3.23 $ 3.24 Pro forma $ 0.69 $ 0.89 $ 3.20 $ 3.17 Cardinal Effective August 1, 2018, we acquired 100 percent of the issued and outstanding shares of Cardinal, a digital solutions provider based in Cincinnati, Ohio, with offices across the Midwest and Southeast United States, for a cash purchase price, net of cash acquired, of approximately $78,400,000, including final working capital and tax gross up adjustments. Cardinal provides technology solutions to digitally transform organizations through their expertise in mobile applications development, Internet of Things and cloud enabled business intelligence. We believe that this acquisition strengthens our services capabilities and will bring value to our clients within our digital innovation services solution offering. The fair value of net assets acquired was approximately $42,360,000, including $27,540,000 of identifiable intangible assets, consisting primarily of customer relationships that will be amortized using the straight line method over the estimated economic life of ten years. We finalized the fair value assumptions for identifiable intangible assets acquired in the fourth quarter of 2018. Goodwill acquired approximated $36,040,000 which was recorded in our North America operating segment. The goodwill is tax deductible. The working capital adjustment in the amount of $762,000 was finalized in the fourth quarter of 2018 and paid in January 2019. Additionally, we finalized the purchase price allocation when the tax gross up adjustment of $2,600,000 was agreed upon in April 2019. This resulted in a reduction of the previously recorded purchase price of $400,000 in the second quarter of 2019. Changes in Goodwill and Intangible Assets Other than the goodwill and intangible assets recorded in conjunction with the acquisitions of Cardinal and PCM, the only other change in consolidated goodwill and intangible assets as of September 30, 2019 compared to the balance as of December 31, 2018 resulted from foreign currency translation adjustments associated with the balances in our EMEA and APAC operating segments.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards In June 2016, the Financial Accounting Standards Board’s (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-13, “Financial Instruments – Credit Losses.” The new standard is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held at each reporting date. The new standard is effective for interim and annual periods beginning after December 15, 2019, and early adoption is permitted. We will adopt the new standard as of January 1, 2020 and do not expect the adoption to have a material effect on our consolidated financial statements. In April 2019, the FASB issued ASU No. 2019-04, “Codification Improvements to Topic 326, Financial Instruments – Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments.” The new standard provides changes for how a company considers expected recoveries and contractual extensions or renewal options when estimating expected credit losses. The new standard is effective with the adoption of ASU No. 2016-13. We will adopt the new standard as of January 1, 2020 and do not expect the adoption to have a material effect on our consolidated financial statements. Effective January 1, 2019, we adopted the FASB ASU No. 2016-02— Leases (Topic 842) Adoption of the new standard resulted in the recording of additional net operating lease ROU assets and lease liabilities of $65,922,000 and $70,512,000, respectively, as of January 1, 2019. The difference between the additional lease assets and lease liabilities reflected existing accrued and prepaid rent balances that were reclassified to the operating lease ROU asset at January 1, 2019. The standard did not materially impact our consolidated net earnings and had no impact on cash flows. There have been no other material changes in or additions to the recently issued accounting standards as previously reported in Note 1 to our Consolidated Financial Statements in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2018 that affect or may affect our current financial statements.
Significant Leases Accounting Policy - Leases	Significant Leases Accounting Policy We determine if a contract or arrangement is, or contains, a lease at inception. Balances related to operating leases are included in other assets, other current liabilities, and other liabilities in our consolidated balance sheet. Balances related to financing leases are included in property and equipment, current portion of long-term debt, and long-term debt in our consolidated balance sheet. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The operating lease ROU asset includes any prepaid lease payments and additional direct costs and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option.
