Organization, Consolidation and Presentation of Financial Statements [Abstract]
Operations and Summary of Significant Accounting Policies	(1) Operations and Summary of Significant Accounting Policies Description of Business We are a Fortune 500-ranked . Operating Segment Geography North America United States and Canada EMEA Europe, Middle East and Africa APAC Asia-Pacific Our offerings in North America and select countries in EMEA and APAC include hardware, software and services. Our offerings in the remainder of our EMEA and APAC segments are largely software and select software-related services. Acquisitions Effective September 1, 2016, we acquired Ignia Pty Ltd (“Ignia”), a business technology consulting and managed services provider headquartered in Perth, Australia, with an additional office in Melbourne, for a cash purchase price, net of cash acquired, of approximately $10,804,000. The acquisition was funded using cash on hand. Effective October 1, 2015, we acquired BlueMetal Architects, Inc. (“BlueMetal”), an interactive design and technology architecture firm based in the Boston area with offices in Chicago and New York, for a cash purchase price, net of cash acquired, of approximately $44,221,000. The acquisition was funded using borrowings under our accounts receivable securitization financing facility. Our results of operations include the results of Ignia and BlueMetal from their acquisition dates of September 1, 2016 and October 1, 2015, respectively. (See Note 22 for a discussion of our acquisitions.) Principles of Consolidation and Presentation 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. References to “the Company,” “Insight,” “we,” “us,” “our” and other similar words refer to Insight Enterprises, Inc. and its consolidated subsidiaries, unless the context suggests otherwise. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“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. Cash and Cash Equivalents We consider all highly liquid investments with maturities at the date of purchase of three months or less to be cash equivalents. Book overdrafts represent the amount by which outstanding checks issued, but not yet presented to our banks for disbursement, exceed balances on deposit in applicable bank accounts and a legal right of offset with our positive cash balances in other financial institution accounts does not exist. Our book overdrafts, which are not directly linked to a credit facility or other bank overdraft arrangement, do not result in an actual bank financing, but rather constitute normal unpaid trade payables at the end of a reporting period. These amounts are included within our accounts payable balance in our consolidated balance sheets. The changes in these book overdrafts are included within the changes in accounts payable line item as a component of cash flows from operating activities in our consolidated statements of cash flows. Allowance for Doubtful Accounts We establish an allowance for doubtful accounts to reflect our best estimate of probable losses inherent in our accounts receivable balance. The allowance is based on our evaluation of the aging of the receivables, historical write-offs and the current economic environment. We write off individual accounts against the reserve when we no longer believe that it is probable that we will collect the receivable because we become aware of a client’s or partner’s inability to meet its financial obligations. Such awareness may be as a result of bankruptcy filings, or deterioration in the client’s or partner’s operating results or financial position. Inventories We state inventories, principally purchased IT hardware, at the lower of weighted average cost (which approximates cost under the first-in, first-out Inventories not available for sale relate to product sales transactions in which we are warehousing the product and will be deploying the product to our clients’ designated locations subsequent to period-end. non-cancelable Property and Equipment We record property and equipment at cost. We capitalize major improvements and betterments, while maintenance, repairs and minor replacements are expensed as incurred. Depreciation or amortization is provided using the straight-line method over the following estimated economic lives of the assets: Estimated Economic Life Leasehold improvements Shorter of underlying lease term or asset life Furniture and fixtures 2 – 7 years Equipment 3 – 5 years Software 3 – 10 years Buildings 29 years Costs incurred to develop internal-use internal-use internal-use Reviews are regularly performed to determine whether facts and circumstances exist which indicate that the useful life is shorter than originally estimated or the carrying amount of assets may not be recoverable. When an indication exists that the carrying amount of long-lived assets may not be recoverable, we assess the recoverability of our assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Such impairment test is based on the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Impairment, if any, is based on the excess of the carrying amount over the estimated fair value of those assets. Goodwill Goodwill is recorded when the purchase price paid for an acquisition exceeds the estimated fair value of net identified tangible and intangible assets acquired. Goodwill is tested for impairment at the reporting unit level on an annual basis in the fourth quarter and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value. We may first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, it is necessary to perform a quantitative two-step two-step two-step Intangible Assets We amortize intangible assets acquired in business combinations using the straight-line method over the following estimated economic lives of the intangible assets from the date of acquisition: Estimated Economic Customer relationships 2 – 11 years Tradenames and Restrictive Covenant Agreements 9 months – 3 years We regularly perform reviews to determine if facts and circumstances exist which indicate that the useful lives of our intangible assets are shorter than originally estimated or the carrying amount of these assets may not be recoverable. When an indication exists that the carrying amount of intangible assets may not be recoverable, we assess the recoverability of our assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Such impairment test is based on the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Impairment, if any, is based on the excess of the carrying amount over the estimated fair value of those assets. Trade Credits Trade credit liabilities arise from aged unclaimed credit memos, duplicate payments, payments for returned product or overpayments made to us by our clients, and, to a lesser extent, from goods received by us from a partner for which we were never invoiced. Trade credit liabilities are included in accrued expenses and other current liabilities in our consolidated balance sheets. We derecognize the liability as a reduction of costs of goods sold only if it has been extinguished, upon either (1) our payment of the liability to relieve our obligation or (2) our legal release from the related obligation. Self Insurance We are self-insured in the United States for medical insurance up to certain annual stop-loss limits and workers’ compensation claims up to certain deductible limits. We establish reserves for claims, both reported and incurred but not reported, using currently available information as well as our historical claims experience. Treasury Stock We record repurchases of our common stock as treasury stock at cost. We also record the subsequent retirement of these treasury shares at cost. The excess of the cost of the shares retired over their par value is allocated between additional paid-in paid-in Sales Recognition Sales are recognized when title and risk of loss are passed to the client, there is persuasive evidence of an arrangement for sale, delivery has occurred and/or services have been rendered, the sales price is fixed or determinable and collectibility is reasonably assured. Our standard sales terms are F.O.B. shipping point or equivalent, at which time title and risk of loss have passed to the client. However, because we either (i) have a general practice of covering client losses while products are in transit despite title and risk of loss contractually transferring at the point of shipment or (ii) have specifically stated F.O.B. destination contractual terms with the client, delivery is not deemed to have occurred until the point in time when the product is received by the client. We leverage drop-shipment arrangements with many of our partners and suppliers to deliver products to our clients without having to physically hold the inventory at our warehouses, thereby increasing efficiency and reducing costs. We recognize revenue for drop-shipment arrangements on a gross basis when the product is received by the client. We recognize revenue on a gross basis as the principal in the transaction because we control the transaction as the primary obligor for product fulfillment in the arrangement, we assume inventory risk if the product is returned by the client, we set the price of the product charged to the client, we assume credit risk for the amounts invoiced, and we work closely with our clients to determine their hardware and software specifications. We make provisions for estimated product returns that we expect to occur under our return policy based upon historical return rates. Our manufacturers warrant most of the products we market, and it is our policy to request that clients return their defective products directly to the manufacturer for warranty service during the manufacturer’s warranty period. On selected products, and for selected client service reasons, we may accept returns directly from the client and then either credit the client or ship a replacement product. We generally offer a limited 15- 30-day We record the freight we bill to our clients as net sales and the related freight costs we pay as costs of goods sold. We report sales net of any sales-based taxes assessed by governmental authorities that are imposed on and concurrent with sales transactions. Revenue is recognized from software sales when clients acquire the right to use or copy software under license, but in no case prior to the commencement of the term of the initial software license agreement, provided that all other revenue recognition criteria have been met (i.e., evidence of the arrangement exists, the fee is fixed or determinable and collectibility of the fee is probable). We sell certain third-party service contracts, software maintenance and Cloud or software-as-a-service We recognize revenue for sales of services ratably over the time period over which the service will be provided if there is no discernible pattern of recognition of the cost to perform the service. Billings for such services that are made in advance of the related revenue recognized are recorded as deferred revenue and recognized as revenue ratably over the billing coverage period. Revenue from certain arrangements that allow for the use of a product or service over a period of time without taking possession of software are also accounted for ratably over the time period over which the service will be provided. We recognize revenue for professional services engagements that are on a time and materials basis based upon hours incurred as the services are performed and amounts are earned. Net sales for these services engagements are not a significant portion of our consolidated net sales. Additionally, we sell certain professional services contracts on a fixed fee basis. Revenues for fixed fee professional services contracts are recognized based on the ratio of costs incurred to total estimated costs. Net sales for these service contracts are not a significant portion of our consolidated net sales. In certain arrangements, we may provide a combination of hardware and software products and the provision of services. Services that are performed by us in conjunction with hardware and software sales that are completed in our facilities prior to shipment of the product are recognized upon delivery, when title passes to the client, for the hardware sale. Net sales of services that are performed at client locations are primarily service-only contracts and are recorded as sales when the services are performed. The total consideration for an arrangement with multiple deliverables is allocated to all deliverables that represent a separate unit of accounting using the relative selling price method. Costs of Goods Sold Costs of goods sold include product costs, direct costs incurred associated with delivering services, outbound and inbound freight costs and provisions for inventory reserves. These costs are reduced by provisions for supplier discounts and certain payments and credits received from partners, as described under “Partner Funding” below. Selling and Administrative Expenses Selling and administrative expenses include salaries and wages, bonuses and incentives, stock-based compensation expense, employee-related expenses, facility-related expenses, marketing and advertising expense, reduced by certain payments and credits received from partners related to shared marketing expense programs, as described under “Partner Funding” below, depreciation of property and equipment, professional fees, amortization of intangible assets, provisions for losses on accounts receivable and other operating expenses. Partner Funding We receive payments and credits from partners, including consideration pursuant to volume sales incentive programs, volume purchase incentive programs and shared marketing expense programs. Partner funding received pursuant to volume sales incentive programs is recognized as it is earned as a reduction to costs of goods sold. Partner funding received pursuant to volume purchase incentive programs is allocated as a reduction to inventories based on the applicable incentives earned from each partner and is recorded in cost of goods sold as the related inventory is sold. Partner funding received pursuant to shared marketing expense programs is recorded as it is earned as a reduction of the related selling and administrative expenses in the period the program takes place if the consideration represents a reimbursement of specific, incremental, identifiable costs. Consideration that exceeds the specific, incremental, identifiable costs is classified as a reduction of costs of goods sold. The amount of partner funding recorded as a reduction of selling and administrative expenses in our statements of operations totaled $45,801,000, $43,311,000 and $40,106,000 in 2016, 2015 and 2014, respectively. Concentrations of Risk Credit Risk Although we are affected by the international economic climate, management does not believe material credit risk concentration existed at December 31, 2016. We monitor our clients’ financial condition and do not require collateral. No single client accounted for more than 3% of our consolidated net sales in 2016. Supplier Risk Purchases from Microsoft accounted for approximately 27% of our aggregate purchases in 2016. No other partner accounted for more than 10% of purchases in 2016. Our top five partners as a group for 2016 were Microsoft, Ingram Micro (a distributor), HP Inc., Cisco and Tech Data (a distributor), and approximately 59% of our total purchases during 2016 came from this group of partners. Although brand names and individual products are important to our business, we believe that competitive sources of supply are available in substantially all of our product categories such that, with the exception of Microsoft, we are not dependent on any single partner for sourcing products. Advertising Costs Advertising costs are expensed as they are incurred. Advertising expense of $37,565,000, $33,568,000 and $31,214,000 was recorded in 2016, 2015 and 2014, respectively. These amounts were predominantly offset by partner funding earned pursuant to shared marketing expense programs recorded as a reduction of selling and administrative expenses, as discussed in “Partner Funding” above. Stock-Based Compensation Stock-based compensation is measured based on the fair value of the award on the date of grant and the corresponding expense is recognized over the period during which an employee is required to provide service in exchange for the reward. Stock-based compensation expense is classified in the same line item of our consolidated statements of operations as other payroll-related expenses specific to the employee. Compensation expense related to service-based restricted stock units (“RSUs”) is recognized on a straight-line basis over the requisite service period for the entire award. Compensation expense related to performance-based RSUs is recognized on a straight-line basis over the requisite service period for each separately vesting portion of the award as if the award was, in-substance, Foreign Currencies We use the U.S. dollar as our reporting currency. The functional currencies of our foreign subsidiaries are the local currencies. Accordingly, assets and liabilities of the subsidiaries are translated into U.S. dollars at the exchange rate in effect at the balance sheet dates. Income and expense items are translated at the average exchange rate for each month within the year. The resulting translation adjustments are recorded directly in accumulated other comprehensive income (loss), net of tax – foreign currency translation adjustments as a separate component of stockholders’ equity. Net foreign currency transaction gains/losses, including transaction gains/losses on intercompany balances that are not of a long-term investment nature and non-functional non-operating Derivative Financial Instruments We enter into forward foreign exchange contracts to mitigate the risk of non-functional non-operating Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable earnings in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period that includes the enactment date. We recognize net deferred tax assets to the extent that we believe these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning We record uncertain tax positions on the basis of a two-step more-likely-than-not 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 year. 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 RSUs. A reconciliation of the denominators of the basic and diluted EPS calculations follows (in thousands, except per share data): Years Ended December 31, 2016 2015 2014 Numerator: Net earnings $ 84,690 $ 75,851 $ 75,684 Denominator: Weighted-average shares used to compute basic EPS 36,102 37,984 41,062 Dilutive potential common shares due to dilutive RSUs, net of tax effect 336 291 296 Weighted-average shares used to compute diluted EPS 36,438 38,275 41,358 Net earnings per share: Basic $ 2.35 $ 2.00 $ 1.84 Diluted $ 2.32 $ 1.98 $ 1.83 In 2016, 2015 and 2014, approximately 36,000, 1,000 and 20,000, 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. Recently Issued Accounting Standards In November 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-18, beginning-of-period end-of-period In August 2016, the FASB issued ASU No. 2016-15, In February 2016, the FASB issued ASU No. 2016-02, 2016-02 In March 2016, FASB issued ASU No. 2016-09, In July 2015, the FASB issued ASU No. 2015-11, On May 28, 2014, the FASB issued ASU No. 2014-09, 2014-09 one-year • We expect to adopt the standard in the first quarter of 2018 and will not early adopt. • We expect to use the cumulative effect transition method. Such method provides that upon applying the new standard, the cumulative effect from prior periods is recognized in our consolidated balance sheet as of the date of adoption, including an adjustment to retained earnings. Prior periods will not be retrospectively adjusted. • We believe that since substantially all of our revenue is contractual, substantially all of our revenue falls within the scope of ASU No. 2014-09, • As discussed above, our hardware and software revenue is generally recognized on a gross basis upon delivery. Third party service contracts, software maintenance and Cloud or software-as-a-service • We believe that the only significant incremental costs incurred to obtain contracts with our clients within the scope of ASU 2014-09, one-year • As discussed above, we hold inventories not available for sale related to certain product sales transactions in which we are warehousing the product and will be deploying the product to our clients’ designated locations subsequent to period-end. • We expect that our disclosures in our notes to our consolidated financial statements related to revenue recognition will be significantly expanded under the new standard. Our analysis and evaluation of the new standard will continue through its effective date in the first quarter of 2018. A substantial amount of work remains to be completed due to the complexity of the new standard, the application of judgment and the requirement for the use of estimates in applying the new standard, as well as the volume of our client portfolio and the related terms and conditions of our contracts that must be reviewed. The quantification of the effects of the new standard, including the items discussed above, is a significant undertaking. Further, we will be required to implement necessary changes in our processes, accounting systems and internal controls in conjunction with applying the new standard.

Goodwill	(3) Goodwill The changes in the carrying amount of goodwill for the year ended December 31, 2016 are as follows (in thousands): North America EMEA APAC Consolidated Goodwill $ 379,617 $ 151,439 $ 13,973 $ 545,029 Accumulated impairment losses (323,422 ) (151,439 ) (13,973 ) (488,834 ) Balance at December 31, 2015 56,195 — — 56,195 Goodwill acquired during 2016 (507 ) — 6,957 6,450 Balance at December 31, 2016 $ 55,688 $ — $ 6,957 $ 62,645 On September 1, 2016, we acquired Ignia, which has been integrated into our APAC business. Under the purchase method of accounting, the purchase price for the acquisition was allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values. The excess purchase price over fair value of net assets acquired of approximately $6,957,000 was recorded as goodwill in the APAC reporting unit (see Note 22). The primary driver for this acquisition was to expand our global footprint in the areas of application design, digital solutions, Cloud, mobility and business analytics, while also building on our unique position to bring solutions powered by Intelligent Technology™ to our clients in the Asia-Pacific region. On October 1, 2015, we acquired BlueMetal, which has been integrated into our North America business. Under the purchase method of accounting, the purchase price for the acquisition was allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values. The excess purchase price over fair value of net assets acquired of approximately $29,938,000 was recorded as goodwill in the North America reporting unit (see Note 22). The primary driver for this acquisition was to strengthen our services capabilities to bring value to our clients’ businesses in the area of application design, mobility and big data. In 2016, we resolved the working capital contingency associated with the acquisition of BlueMetal. We recorded the adjustment of the purchase price allocation as a reduction of goodwill in our North America operating segment upon the receipt of $507,000 in cash during 2016. During 2016, we periodically assessed whether any indicators of impairment existed which would require us to perform an interim impairment review. As of each interim period end during the year, we concluded that a triggering event had not occurred that would more likely than not reduce the fair value of our reporting units below their carrying values. We performed our annual test of goodwill for impairment during the fourth quarter of 2016. The results of the first step of the two-step

As such, the gross intangible assets balance and the accumulated amortization balance were both reduced by approximately $81,817,000, having no effect on the net intangible assets balance reported in the accompanying consolidated balance sheet as of December 31, 2016. During 2016, we periodically assessed whether any indicators of impairment existed related to our intangible assets. As of each interim period end during the year, we concluded that a triggering event had not occurred that would more likely than not reduce the fair value of our intangible assets below their carrying values.

Accounts Payable - Inventory Financing Facility	(5) Accounts Payable - Inventory Financing Facility We have entered into an agreement with a financial intermediary to facilitate the purchase of inventory from various suppliers under certain terms and conditions, as described below. These amounts are classified separately as accounts payable - inventory financing facility in the accompanying consolidated balance sheets. The aggregate availability for vendor purchases under our inventory financing facility is $325,000,000. Prior to June 23, 2016, the maximum borrowing capacity was $250,000,000. From time to time and at our option, we may request to increase the aggregate amount available under the inventory financing facility by up to an aggregate of $25,000,000, subject to customary conditions. The facility matures on June 23, 2021. Additionally, the facility may be renewed under certain circumstances described in the agreement for successive 12-month

Debt, Capital Lease and Other Financing Obligations	(6) Debt, Capital Lease and Other Financing Obligations Debt Our long-term debt consists of the following (in thousands): December 31, 2016 2015 Senior revolving credit facility $ — $ — Accounts receivable securitization financing facility 39,500 89,000 Capital leases and other financing obligations 1,231 1,535 Total 40,731 90,535 Less: current portion of capital leases and other financing obligations (480 ) (1,535 ) Less: current portion of revolving credit facilities — — Long-term debt $ 40,251 $ 89,000 On June 23, 2016, we entered into amendments to our senior revolving credit facility (“revolving facility”) and our accounts receivable securitization financing facility (“ABS facility”). The revolving facility is used for general corporate purposes, which may include acquisitions and share repurchases, and may be used for borrowings in certain foreign currencies and for letters of credit, in each case up to specified sublimits. Although the maximum borrowing capacity remained at an aggregate U.S. dollar equivalent amount of $350,000,000, our revolving facility was amended to increase the portion of the maximum borrowing capacity that may be used for borrowing in certain foreign currencies from $25,000,000 to $50,000,000. From time to time and at our option, we may request to increase the aggregate amount available for borrowing under the revolving facility by up to an aggregate of the U.S. dollar equivalent of $175,000,000, subject to customary conditions. (See Note 23 for a discussion of our amendment to the revolving facility effective January 6, 2017.) The revolving facility is guaranteed by the Company’s material domestic subsidiaries and is secured by a lien on substantially all of the Company’s and each guarantor’s assets. The interest rates applicable to borrowings under the revolving facility are based on the leverage ratio of the Company as set forth on a pricing grid in the amended agreement. Amounts outstanding under the revolving facility bear interest, payable quarterly, at a floating rate equal to the prime rate plus a predetermined spread of 0.00% to 0.75% or, at our option, a LIBOR rate plus a pre-determined Our ABS facility was amended in June 2016 to increase the aggregate borrowing availability from $200,000,000 to $250,000,000, to renew the borrowing program under the ABS facility for a three-year term expiring June 23, 2019, and to modify interest rates and fees for used and unused capacity under the facility. Under our ABS facility, we can sell receivables periodically to a special purpose accounts receivable and financing entity (the “SPE”), which is exclusively engaged in purchasing receivables from us. The SPE is a wholly-owned, bankruptcy-remote entity that we have included in our consolidated financial statements. The SPE funds its purchases by selling undivided interests in eligible trade accounts receivable to independent financial institution purchasers under the ABS facility (“Purchasers”), which is administered by an independent financial institution agent. The SPE’s assets are available first and foremost to satisfy the claims of the Purchasers, and we cannot convey any interest in the receivables sold to the Purchasers (or allow any adverse claims on the receivables) without the consent of the Purchasers. In addition, the SPE is required to maintain a minimum capital amount and various reserves pursuant to the terms of the ABS facility. We maintain effective control over the receivables that are sold. Accordingly, the receivables remain recorded on our consolidated balance sheets. At December 31, 2016 and 2015, the SPE owned $936,467,000 and $849,336,000, respectively, of receivables recorded at fair value and included in the accompanying consolidated balance sheets. While the ABS facility has a stated maximum amount, the actual availability under the ABS facility is limited by the quantity and quality of the underlying accounts receivable. As of December 31, 2016, qualified receivables were sufficient to permit access to the full $250,000,000 facility amount, of which $39,500,000 was outstanding. See discussion of the maximum leverage ratio under “Debt Covenants” below. Under the amended ABS facility, interest is payable monthly, and the floating interest rate applicable at December 31, 2016 was 1.73% per annum, including a 0.85% usage fee on any outstanding balances. In addition, we pay a monthly commitment fee on the unused portion of the facility of 0.375%. In conjunction with the amendment to the ABS facility in June 2016, an immaterial amount of unamortized capitalized deferred financing fees were written off to interest expense, and an additional $410,000 of deferred financing fees were capitalized. Such fees are being amortized to interest expense over the term of the facility. During the years ended December 31, 2016, 2015 and 2014, the weighted average interest rates on amounts outstanding under our ABS facility, including the usage and commitment fees and the amortization of deferred financing fees, were 1.9%, 1.6% and 1.7%, respectively. Weighted average borrowings under our ABS facility in 2016, 2015 and 2014 were $145,376,000, $112,101,000 and $105,992,000, respectively. Debt Covenants Our revolving facility and our ABS facility contain various covenants customary for transactions of this type, including limitations on the payment of dividends and the requirement that we comply with maximum leverage and minimum fixed charge ratio requirements, comply with a minimum receivables requirement and meet monthly, quarterly and annual reporting requirements. If we fail to comply with these covenants, the lenders would be able to demand payment within a specified period of time. Further, the terms of the ABS facility identify various circumstances that would result in an “amortization event” under the facility. Our consolidated debt balance that can be outstanding at the end of any fiscal quarter under our revolving facility and our ABS facility is limited by certain financial covenants, particularly a maximum leverage ratio. The maximum leverage ratio is calculated as aggregate debt outstanding divided by the sum of our trailing twelve month net earnings (loss) plus (i) interest expense, excluding non-cash (iv) non-cash non-recurring non-cash twelve-month Capital Lease and Other Financing Obligations In March 2016, we entered into a new capitalized lease with a 36-month non-cash From time to time, we also enter into other financing agreements with financial intermediaries to facilitate the purchase of products from certain vendors. At December 31, 2015, amounts owed under other financing agreements of $1,309,000 are included in our current debt balance as summarized in the table above. No amounts were owed under other financing agreements as of December 31, 2016.

The Plan was approved by our stockholders on May 18, 2011 at our 2011 annual meeting and, unless sooner terminated, will remain in place until May 18, 2021. The Plan allows the Company to grant options, stock appreciation rights, stock awards, restricted stock, stock units (which may also be referred to as “restricted stock units”), performance shares, performance units, cash-based awards and other awards payable in cash or shares of common stock to eligible non-employee On February 17, 2016, the Board of Directors adopted the First Amendment to the Plan (the “First Amendment”). On May 18, 2016 at our 2016 annual meeting, our stockholders approved the First Amendment. The First Amendment: (a) updates the list of performance criteria contained in Section 16.1 of the Plan; (b) imposes a limit on the dollar value of awards that may be granted to any one participant who is a non-employee The Plan is administered by the Compensation Committee of Insight’s Board of Directors, and, except as provided below, the Compensation Committee has the exclusive authority to administer the Plan, including the power to determine eligibility, the types of awards to be granted, the price and the timing of awards. Under the Plan, the Compensation Committee may delegate some of its authority to our Chief Executive Officer to grant awards to individuals other than individuals who are subject to the reporting requirements of Section 16(a) of the Securities Exchange Act of 1934, as amended. As of December 31, 2016, of the 7,250,000 shares of common stock reserved and available for grant under the Plan, 3,384,684 shares of common stock remain available for grant under the Plan. Accounting for Restricted Stock Units We issue RSUs as incentives to certain officers and teammates and as compensation to members of our Board of Directors. We recognize compensation expense associated with the issuance of such RSUs over the vesting period for each respective RSU. The total compensation expense associated with RSUs represents the value based upon the number of RSUs awarded multiplied by the closing price of our common stock on the date of grant, adjusted for our estimate of forfeitures. The number of RSUs to be awarded under our service-based RSUs is fixed at the grant date. The number of RSUs ultimately awarded under our performance-based RSUs varies based on whether the Company achieves certain financial results. We record compensation expense each period based on our estimate of the most probable number of RSUs that will be issued under the grants of performance-based RSUs. Recipients of RSUs do not have voting or dividend rights until the vesting conditions are satisfied and shares are released. As of December 31, 2016, total compensation cost related to nonvested RSUs not yet recognized is $15,986,000, which is expected to be recognized over the next 1.24 years on a weighted-average basis. The following table summarizes our RSU activity during 2016: Number Weighted Average Grant Date Fair Value Fair Value Nonvested at the beginning of year 951,784 $ 24.35 Granted 551,675 $ 25.97 Vested, including shares withheld to cover taxes (354,487 ) $ 23.56 $ 9,235,102 (a) Forfeited (81,415 ) $ 25.32 Nonvested at the end of year 1,067,557 $ 25.37 $ 43,172,005 (b) Expected to vest 1,003,490 $ 40,581,136 (b) (a) The aggregate fair value of vested RSUs represents the total pre-tax (b) The aggregate fair value of the nonvested RSUs and the RSUs expected to vest represents the total pre-tax During each of the years in the three-year period ended December 31, 2016, the RSUs that vested for teammates in the United States were net-share net-share

The change, which increased our U.S. federal income taxes, affects our foreign entities that are treated as branches for U.S. tax purposes. The “Other, net” line item in the schedule above includes $1,296,000 related to the effect of non-deductible For foreign entities not treated as branches for U.S. tax purposes, we do not provide for U.S. income taxes on the undistributed earnings of these subsidiaries as these earnings are reinvested and, in the opinion of management, will continue to be reinvested indefinitely outside of the United States. The undistributed earnings of foreign subsidiaries that are deemed to be indefinitely invested outside of the United States were approximately $105,291,000 at December 31, 2016. It is not practicable to determine the unrecognized deferred tax liability on those earnings. The significant components of deferred tax assets and liabilities are as follows (in thousands): December 31, 2016 2015 Deferred tax assets: Goodwill and other intangibles $ 34,302 $ 42,281 Net operating losses 18,964 17,433 Foreign tax credits 13,115 12,972 Accruals 6,315 7,423 Stock-based compensation 4,238 3,558 Inventories 2,598 2,667 Accounts receivable 2,547 3,749 Deferred revenue 468 351 Property and equipment 20 — Other 56 2,391 Gross deferred tax assets 82,623 92,825 Valuation allowances (30,972 ) (28,750 ) Total deferred tax assets 51,651 64,075 Deferred tax liabilities: Prepaid expenses (204 ) (226 ) Property and equipment — (1,102 ) Total deferred tax liabilities (204 ) (1,328 ) Net deferred tax assets $ 51,447 $ 62,747 The net non-current December 31, 2016 2015 Net non-current $ 52,347 $ 62,986 Net non-current (900 ) (239 ) Net deferred tax assets $ 51,447 $ 62,747 As of December 31, 2016, we have U.S. state net operating loss carryforwards (“NOLs”) of $388,000 that will expire between 2016 and 2031. We also have NOLs from various non-U.S. non-U.S. On the basis of currently available information, we have provided valuation allowances for certain of our deferred tax assets where we believe it is more likely than not that the related tax benefits will not be realized. At December 31, 2016 and 2015, our valuation allowances totaled $30,972,000 and $28,750,000, respectively, representing non-U.S. We believe it is more likely than not that forecasted income, including income that may be generated as a result of prudent and feasible tax planning strategies, together with the tax effects of deferred tax liabilities, will be sufficient to fully recover our remaining deferred tax assets. In the future, if we determine that realization of the remaining deferred tax assets and the availability of certain previously paid taxes to be refunded are not more likely than not, we will need to increase our valuation allowances and record additional income tax expense. The following table summarizes the change in the valuation allowance (in thousands): December 31, 2016 2015 Valuation allowances at beginning of year $ 28,750 $ 28,709 Increase in income tax expense 3,742 2,944 Foreign currency translation adjustments (1,035 ) (1,743 ) Other (485 ) (1,160 ) Valuation allowances at end of year $ 30,972 $ 28,750 Various taxing jurisdictions are examining our tax returns for certain tax years. Although the outcome of tax audits cannot be predicted with certainty, management believes the ultimate resolution of these examinations will not result in a material adverse effect to our financial position, results of operations or cash flows. As of December 31, 2016 and 2015, we had approximately $2,246,000 and $3,335,000, respectively, of unrecognized tax benefits. Of these amounts, approximately $195,000 and $296,000, respectively, related to accrued interest. A reconciliation of the beginning and ending amounts of unrecognized tax benefits, excluding interest, is as follows (in thousands): Balance at December 31, 2015 $ 3,039 Additions for tax positions in prior periods 31 Additions for tax positions in current period 366 Subtractions due to foreign currency translation (33 ) Subtractions due to audit settlements and statute expirations (1,352 ) Balance at December 31, 2016 $ 2,051 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 2014. 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 significantly 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. We, including our subsidiaries, file income tax returns in the U.S. federal jurisdiction and many state and local and non-U.S. non-U.S.

Market Risk Management	(12) Market Risk Management Interest Rate Risk We have interest rate exposure arising from our financing facilities, which have variable interest rates. These variable interest rates are affected by changes in short-term We do not believe that the effect of reasonably possible near-term changes in interest rates will be material to our financial position, results of operations and cash flows. Our financing facilities expose our net earnings to changes in short-term pre-tax Foreign Currency Exchange Risk We have foreign currency exchange risk related to the translation of our foreign subsidiaries’ operating results, assets and liabilities (see Note 1 for a description of our Foreign Currencies policy). We also maintain cash accounts denominated in currencies other than the functional currency, which expose us to fluctuations in foreign exchange rates. Remeasurement of these cash balances results in gains/losses that are also reported as a separate component of non-operating non-functional non-functional non-operating non-performance

Derivative Financial Instruments	(13) Derivative Financial Instruments We use derivatives to partially offset our exposure to fluctuations in certain foreign currencies. We do not enter into derivative contracts for speculative or trading purposes. Derivatives are recorded at fair value on the balance sheet based on observable market based inputs or unobservable inputs that are corroborated by market data (Level 2). Gains or losses resulting from changes in fair value of the derivative are recorded currently in income. We do not designate our hedges for hedge accounting, and our foreign currency derivative instruments are not subject to any master netting arrangements with our counterparties. We use foreign exchange forward contracts to mitigate risk associated with certain non-functional non-functional Our derivative financial instruments as of December 31, 2016 were not material. The effect of our derivative financial instruments on our results of operations during the years ended December 31, 2016, 2015 and 2014 were a loss of $2,722,000, a loss of $942,000 and a loss of $205,000, respectively. These amounts are reported within the net foreign currency exchange (gain) loss line item in our consolidated statements of operations.

Fair Value Disclosures [Abstract]
Fair Value Measurements	(14) Fair Value Measurements Fair value measurements are determined based on the following three categories: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs that are not corroborated by market data. We have elected to use the income approach to value our foreign exchange derivatives, using observable Level 2 market expectations at the measurement date and standard valuation techniques to convert future amounts to a single present value amount assuming that participants are motivated, but not compelled, to transact. Level 2 inputs for the valuations are limited to quoted prices for similar assets or liabilities in active markets and inputs other than quoted prices that are observable for the asset or liability (specifically LIBOR rates, foreign exchange rates, and foreign exchange forward points).

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	(17) 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 December 31, 2016, we had approximately $2,198,000 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. Employment Contracts and Severance Plans We have employment contracts with, and 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 December 31, 2016. Accordingly, we have not accrued any liabilities related to such indemnifications in the accompanying 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 our 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 arising in the ordinary course of 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, claims of alleged non-compliance The Company is not involved in any pending or threatened legal proceedings that it believes would reasonably be expected to have a material adverse effect on its financial condition, results of operations or liquidity.

Related Party Transactions [Abstract]
Related Party Transaction	(18) Related Party Transaction In December 2014, we sold a Company-owned 21,375 square feet facility (and its furnishings) that previously served as executive offices and administration space in Tempe, Arizona to a trust. Timothy A. Crown, the Chair of our Board of Directors, serves as trustee of that trust. For approximately twelve months prior to the sale, the facility had been leased to another entity in which Mr. Crown has an interest. Annual rent was not material and was based on a review by our outside real estate brokerage adviser of comparable rentals in the relevant market area. The facility was sold for $2,500,000, the full appraisal value based on two property valuations provided by independent real estate brokers. The Audit Committee approved the sale of the facility, as required under the Company’s Code of Ethics and Business Practices and other applicable policies, practices and requirements. The Company was not required to pay a commission. Total proceeds from the sale of $2,472,000, net of related closing costs and fees, were collected in December 2014, and no amounts related to this transaction remain outstanding. During 2014, the Company recognized a gain of $895,000 on the sale of the facility.

Since these aged accounts receivable had been fully reserved against, the write off was accomplished through the elimination of the associated allowance, with no effect on net accounts receivable balances. The reduction of the allowance for doubtful accounts from $19,336,000 at December 31, 2014 to $11,872,000 at December 31, 2015 was a direct result of the write off of these older fully reserved accounts receivable as well as an overall improvement in managing the receivables portfolio.

Our offerings in North America and select 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 select software-related services.

Our CODM is our Chief Executive Officer. 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 in 2016, 2015 or 2014. 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 considered to be a reasonable reflection of the utilization of services provided to or benefits received by the operating segments.

Acquisition

Business Combinations [Abstract]
Acquisition	(22) Acquisition Effective September 1, 2016, we acquired Ignia, a business technology consulting and managed services provider headquartered in Perth, Australia, with an additional office in Melbourne, for a cash purchase price, net of cash acquired, of approximately $10,804,000, subject to a final working capital adjustment. We believe that this acquisition expands our global footprint in the areas of application design, digital solutions, Cloud, mobility and business analytics, while also building on our unique position to bring solutions powered by Intelligent Technology™ to our clients in the Asia-Pacific region. The total fair value of net identifiable assets acquired initially recorded was approximately $5,324,000, including $1,463,000 of cash acquired and $4,716,000 of identifiable intangible assets, consisting primarily of customer relationships and restrictive covenant agreements which are being amortized using the straight-line method over their estimated economic lives of eight years and 27 months, respectively. The preliminary purchase price was allocated using the information available at the time. During the fourth quarter of 2016, we finalized the fair value assumptions for identifiable intangible assets acquired and reduced the fair value of identifiable intangible assets acquired by approximately $218,000. Goodwill initially recorded of approximately $7,248,000, which was recorded in our APAC operating segment, was adjusted to $6,957,000 as of December 31, 2016 as a result of the net effects of the decrease in the value of acquired identifiable intangible assets noted previously and foreign currency translation adjustments. None of the goodwill is tax deductible. We will finalize the purchase price allocation in the first quarter of 2017 when the final working capital adjustment is agreed upon and paid and the evaluation of uncertain tax positions, which could lead to an adjustment of the purchase price allocation, is completed. We consolidated the results of operations for Ignia within our APAC operating segment beginning on September 1, 2016, the effective date of the acquisition. Our historical results would not have been materially affected by the acquisition of Ignia and, accordingly, we have not presented pro forma information as if the acquisition had been completed at the beginning of each period presented in our statements of operations. Effective October 1, 2015, we acquired BlueMetal, an interactive design and technology architecture firm based in the Boston area, with offices in Chicago and New York, for a cash purchase price, net of cash acquired, of approximately $44,221,000. BlueMetal delivers strategic design, application development, business intelligence solutions and data visualization platforms, and we believe this acquisition strengthens our services capabilities to bring value to our clients’ businesses in the area of application design, mobility and big data. The total fair value of net assets acquired was approximately $15,412,000, including $15,240,000 of identifiable intangible assets, consisting primarily of customer relationships and restrictive covenant agreements which are being amortized using the straight-line method over their estimated economic lives of eight and three years, respectively. Goodwill acquired approximated $29,938,000, which was recorded in our North America operating segment. In 2016, we resolved the working capital contingency associated with the acquisition of BlueMetal. We recorded an adjustment of the purchase price as a reduction of goodwill in our North America operating segment upon the receipt of $507,000 in cash during 2016. The addition of the BlueMetal employees to our team and the opportunity to grow our services business are the primary factors making up the goodwill recognized as part of the transaction. None of the goodwill is tax deductible. We consolidated the results of operations for BlueMetal beginning on October 1, 2015, the effective date of the acquisition. Our historical results would not have been materially affected by the acquisition of BlueMetal and, accordingly, we have not presented pro forma information as if the acquisition had been completed at the beginning of each period presented in our statements of operations.

Subsequent Events [Abstract]
Subsequent Event	(23) Subsequent Event On January 6, 2017, we completed our acquisition of Datalink for a cash purchase price of approximately $257,500,000. We funded the acquisition through a combination of cash on hand and approximately $196,000,000 in borrowings under our revolving facility. In conjunction with the acquisition, we amended our revolving facility to expand the facility by $175,000,000 in the form of an incremental Term Loan A (“TLA”). Pricing, maturity and all other general terms and conditions of the TLA are governed by the existing revolving facility. The TLA requires amortization payments of 5%, 7.5%, 10%, 12.5% and 15% in years one through five, respectively. We are in the process of determining the fair value of net assets acquired, including identifiable intangible assets, which will be recorded in our North America operating segment. We will consolidate the results of operations for Datalink beginning on January 6, 2017, the effective date of the acquisition.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business We are a Fortune 500-ranked . Operating Segment Geography North America United States and Canada EMEA Europe, Middle East and Africa APAC Asia-Pacific Our offerings in North America and select countries in EMEA and APAC include hardware, software and services. Our offerings in the remainder of our EMEA and APAC segments are largely software and select software-related services. Acquisitions Effective September 1, 2016, we acquired Ignia Pty Ltd (“Ignia”), a business technology consulting and managed services provider headquartered in Perth, Australia, with an additional office in Melbourne, for a cash purchase price, net of cash acquired, of approximately $10,804,000. The acquisition was funded using cash on hand. Effective October 1, 2015, we acquired BlueMetal Architects, Inc. (“BlueMetal”), an interactive design and technology architecture firm based in the Boston area with offices in Chicago and New York, for a cash purchase price, net of cash acquired, of approximately $44,221,000. The acquisition was funded using borrowings under our accounts receivable securitization financing facility. Our results of operations include the results of Ignia and BlueMetal from their acquisition dates of September 1, 2016 and October 1, 2015, respectively. (See Note 22 for a discussion of our acquisitions.)
Principles of Consolidation and Presentation	Principles of Consolidation and Presentation 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. References to “the Company,” “Insight,” “we,” “us,” “our” and other similar words refer to Insight Enterprises, Inc. and its consolidated subsidiaries, unless the context suggests otherwise.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“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.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all highly liquid investments with maturities at the date of purchase of three months or less to be cash equivalents. Book overdrafts represent the amount by which outstanding checks issued, but not yet presented to our banks for disbursement, exceed balances on deposit in applicable bank accounts and a legal right of offset with our positive cash balances in other financial institution accounts does not exist. Our book overdrafts, which are not directly linked to a credit facility or other bank overdraft arrangement, do not result in an actual bank financing, but rather constitute normal unpaid trade payables at the end of a reporting period. These amounts are included within our accounts payable balance in our consolidated balance sheets. The changes in these book overdrafts are included within the changes in accounts payable line item as a component of cash flows from operating activities in our consolidated statements of cash flows.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts We establish an allowance for doubtful accounts to reflect our best estimate of probable losses inherent in our accounts receivable balance. The allowance is based on our evaluation of the aging of the receivables, historical write-offs and the current economic environment. We write off individual accounts against the reserve when we no longer believe that it is probable that we will collect the receivable because we become aware of a client’s or partner’s inability to meet its financial obligations. Such awareness may be as a result of bankruptcy filings, or deterioration in the client’s or partner’s operating results or financial position.
Inventories	Inventories We state inventories, principally purchased IT hardware, at the lower of weighted average cost (which approximates cost under the first-in, first-out Inventories not available for sale relate to product sales transactions in which we are warehousing the product and will be deploying the product to our clients’ designated locations subsequent to period-end. non-cancelable
Property and Equipment	Property and Equipment We record property and equipment at cost. We capitalize major improvements and betterments, while maintenance, repairs and minor replacements are expensed as incurred. Depreciation or amortization is provided using the straight-line method over the following estimated economic lives of the assets: Estimated Economic Life Leasehold improvements Shorter of underlying lease term or asset life Furniture and fixtures 2 – 7 years Equipment 3 – 5 years Software 3 – 10 years Buildings 29 years Costs incurred to develop internal-use internal-use internal-use Reviews are regularly performed to determine whether facts and circumstances exist which indicate that the useful life is shorter than originally estimated or the carrying amount of assets may not be recoverable. When an indication exists that the carrying amount of long-lived assets may not be recoverable, we assess the recoverability of our assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Such impairment test is based on the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Impairment, if any, is based on the excess of the carrying amount over the estimated fair value of those assets.
Goodwill	Goodwill Goodwill is recorded when the purchase price paid for an acquisition exceeds the estimated fair value of net identified tangible and intangible assets acquired. Goodwill is tested for impairment at the reporting unit level on an annual basis in the fourth quarter and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value. We may first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, it is necessary to perform a quantitative two-step two-step two-step
Intangible Assets	Intangible Assets We amortize intangible assets acquired in business combinations using the straight-line method over the following estimated economic lives of the intangible assets from the date of acquisition: Estimated Economic Customer relationships 2 – 11 years Tradenames and Restrictive Covenant Agreements 9 months – 3 years We regularly perform reviews to determine if facts and circumstances exist which indicate that the useful lives of our intangible assets are shorter than originally estimated or the carrying amount of these assets may not be recoverable. When an indication exists that the carrying amount of intangible assets may not be recoverable, we assess the recoverability of our assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Such impairment test is based on the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Impairment, if any, is based on the excess of the carrying amount over the estimated fair value of those assets.
Trade Credits	Trade Credits Trade credit liabilities arise from aged unclaimed credit memos, duplicate payments, payments for returned product or overpayments made to us by our clients, and, to a lesser extent, from goods received by us from a partner for which we were never invoiced. Trade credit liabilities are included in accrued expenses and other current liabilities in our consolidated balance sheets. We derecognize the liability as a reduction of costs of goods sold only if it has been extinguished, upon either (1) our payment of the liability to relieve our obligation or (2) our legal release from the related obligation.
Self Insurance	Self Insurance We are self-insured in the United States for medical insurance up to certain annual stop-loss limits and workers’ compensation claims up to certain deductible limits. We establish reserves for claims, both reported and incurred but not reported, using currently available information as well as our historical claims experience.
Treasury Stock	Treasury Stock We record repurchases of our common stock as treasury stock at cost. We also record the subsequent retirement of these treasury shares at cost. The excess of the cost of the shares retired over their par value is allocated between additional paid-in paid-in
Sales Recognition	Sales Recognition Sales are recognized when title and risk of loss are passed to the client, there is persuasive evidence of an arrangement for sale, delivery has occurred and/or services have been rendered, the sales price is fixed or determinable and collectibility is reasonably assured. Our standard sales terms are F.O.B. shipping point or equivalent, at which time title and risk of loss have passed to the client. However, because we either (i) have a general practice of covering client losses while products are in transit despite title and risk of loss contractually transferring at the point of shipment or (ii) have specifically stated F.O.B. destination contractual terms with the client, delivery is not deemed to have occurred until the point in time when the product is received by the client. We leverage drop-shipment arrangements with many of our partners and suppliers to deliver products to our clients without having to physically hold the inventory at our warehouses, thereby increasing efficiency and reducing costs. We recognize revenue for drop-shipment arrangements on a gross basis when the product is received by the client. We recognize revenue on a gross basis as the principal in the transaction because we control the transaction as the primary obligor for product fulfillment in the arrangement, we assume inventory risk if the product is returned by the client, we set the price of the product charged to the client, we assume credit risk for the amounts invoiced, and we work closely with our clients to determine their hardware and software specifications. We make provisions for estimated product returns that we expect to occur under our return policy based upon historical return rates. Our manufacturers warrant most of the products we market, and it is our policy to request that clients return their defective products directly to the manufacturer for warranty service during the manufacturer’s warranty period. On selected products, and for selected client service reasons, we may accept returns directly from the client and then either credit the client or ship a replacement product. We generally offer a limited 15- 30-day We record the freight we bill to our clients as net sales and the related freight costs we pay as costs of goods sold. We report sales net of any sales-based taxes assessed by governmental authorities that are imposed on and concurrent with sales transactions. Revenue is recognized from software sales when clients acquire the right to use or copy software under license, but in no case prior to the commencement of the term of the initial software license agreement, provided that all other revenue recognition criteria have been met (i.e., evidence of the arrangement exists, the fee is fixed or determinable and collectibility of the fee is probable). We sell certain third-party service contracts, software maintenance and Cloud or software-as-a-service We recognize revenue for sales of services ratably over the time period over which the service will be provided if there is no discernible pattern of recognition of the cost to perform the service. Billings for such services that are made in advance of the related revenue recognized are recorded as deferred revenue and recognized as revenue ratably over the billing coverage period. Revenue from certain arrangements that allow for the use of a product or service over a period of time without taking possession of software are also accounted for ratably over the time period over which the service will be provided. We recognize revenue for professional services engagements that are on a time and materials basis based upon hours incurred as the services are performed and amounts are earned. Net sales for these services engagements are not a significant portion of our consolidated net sales. Additionally, we sell certain professional services contracts on a fixed fee basis. Revenues for fixed fee professional services contracts are recognized based on the ratio of costs incurred to total estimated costs. Net sales for these service contracts are not a significant portion of our consolidated net sales. In certain arrangements, we may provide a combination of hardware and software products and the provision of services. Services that are performed by us in conjunction with hardware and software sales that are completed in our facilities prior to shipment of the product are recognized upon delivery, when title passes to the client, for the hardware sale. Net sales of services that are performed at client locations are primarily service-only contracts and are recorded as sales when the services are performed. The total consideration for an arrangement with multiple deliverables is allocated to all deliverables that represent a separate unit of accounting using the relative selling price method.
Costs of Goods Sold	Costs of Goods Sold Costs of goods sold include product costs, direct costs incurred associated with delivering services, outbound and inbound freight costs and provisions for inventory reserves. These costs are reduced by provisions for supplier discounts and certain payments and credits received from partners, as described under “Partner Funding” below.
Selling and Administrative Expenses	Selling and Administrative Expenses Selling and administrative expenses include salaries and wages, bonuses and incentives, stock-based compensation expense, employee-related expenses, facility-related expenses, marketing and advertising expense, reduced by certain payments and credits received from partners related to shared marketing expense programs, as described under “Partner Funding” below, depreciation of property and equipment, professional fees, amortization of intangible assets, provisions for losses on accounts receivable and other operating expenses.
Partner Funding	Partner Funding We receive payments and credits from partners, including consideration pursuant to volume sales incentive programs, volume purchase incentive programs and shared marketing expense programs. Partner funding received pursuant to volume sales incentive programs is recognized as it is earned as a reduction to costs of goods sold. Partner funding received pursuant to volume purchase incentive programs is allocated as a reduction to inventories based on the applicable incentives earned from each partner and is recorded in cost of goods sold as the related inventory is sold. Partner funding received pursuant to shared marketing expense programs is recorded as it is earned as a reduction of the related selling and administrative expenses in the period the program takes place if the consideration represents a reimbursement of specific, incremental, identifiable costs. Consideration that exceeds the specific, incremental, identifiable costs is classified as a reduction of costs of goods sold. The amount of partner funding recorded as a reduction of selling and administrative expenses in our statements of operations totaled $45,801,000, $43,311,000 and $40,106,000 in 2016, 2015 and 2014, respectively.
Concentrations of Risk	Concentrations of Risk Credit Risk Although we are affected by the international economic climate, management does not believe material credit risk concentration existed at December 31, 2016. We monitor our clients’ financial condition and do not require collateral. No single client accounted for more than 3% of our consolidated net sales in 2016. Supplier Risk Purchases from Microsoft accounted for approximately 27% of our aggregate purchases in 2016. No other partner accounted for more than 10% of purchases in 2016. Our top five partners as a group for 2016 were Microsoft, Ingram Micro (a distributor), HP Inc., Cisco and Tech Data (a distributor), and approximately 59% of our total purchases during 2016 came from this group of partners. Although brand names and individual products are important to our business, we believe that competitive sources of supply are available in substantially all of our product categories such that, with the exception of Microsoft, we are not dependent on any single partner for sourcing products.
Advertising Costs	Advertising Costs Advertising costs are expensed as they are incurred. Advertising expense of $37,565,000, $33,568,000 and $31,214,000 was recorded in 2016, 2015 and 2014, respectively. These amounts were predominantly offset by partner funding earned pursuant to shared marketing expense programs recorded as a reduction of selling and administrative expenses, as discussed in “Partner Funding” above.
Stock-Based Compensation	Stock-Based Compensation Stock-based compensation is measured based on the fair value of the award on the date of grant and the corresponding expense is recognized over the period during which an employee is required to provide service in exchange for the reward. Stock-based compensation expense is classified in the same line item of our consolidated statements of operations as other payroll-related expenses specific to the employee. Compensation expense related to service-based restricted stock units (“RSUs”) is recognized on a straight-line basis over the requisite service period for the entire award. Compensation expense related to performance-based RSUs is recognized on a straight-line basis over the requisite service period for each separately vesting portion of the award as if the award was, in-substance,
Foreign Currencies	Foreign Currencies We use the U.S. dollar as our reporting currency. The functional currencies of our foreign subsidiaries are the local currencies. Accordingly, assets and liabilities of the subsidiaries are translated into U.S. dollars at the exchange rate in effect at the balance sheet dates. Income and expense items are translated at the average exchange rate for each month within the year. The resulting translation adjustments are recorded directly in accumulated other comprehensive income (loss), net of tax – foreign currency translation adjustments as a separate component of stockholders’ equity. Net foreign currency transaction gains/losses, including transaction gains/losses on intercompany balances that are not of a long-term investment nature and non-functional non-operating
Derivative Financial Instruments	Derivative Financial Instruments We enter into forward foreign exchange contracts to mitigate the risk of non-functional non-operating
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable earnings in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period that includes the enactment date. We recognize net deferred tax assets to the extent that we believe these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning We record uncertain tax positions on the basis of a two-step more-likely-than-not
Net Earnings Per Share ("EPS")	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 year. 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 RSUs. A reconciliation of the denominators of the basic and diluted EPS calculations follows (in thousands, except per share data): Years Ended December 31, 2016 2015 2014 Numerator: Net earnings $ 84,690 $ 75,851 $ 75,684 Denominator: Weighted-average shares used to compute basic EPS 36,102 37,984 41,062 Dilutive potential common shares due to dilutive RSUs, net of tax effect 336 291 296 Weighted-average shares used to compute diluted EPS 36,438 38,275 41,358 Net earnings per share: Basic $ 2.35 $ 2.00 $ 1.84 Diluted $ 2.32 $ 1.98 $ 1.83 In 2016, 2015 and 2014, approximately 36,000, 1,000 and 20,000, 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.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In November 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-18, beginning-of-period end-of-period In August 2016, the FASB issued ASU No. 2016-15, In February 2016, the FASB issued ASU No. 2016-02, 2016-02 In March 2016, FASB issued ASU No. 2016-09, In July 2015, the FASB issued ASU No. 2015-11, On May 28, 2014, the FASB issued ASU No. 2014-09, 2014-09 one-year • We expect to adopt the standard in the first quarter of 2018 and will not early adopt. • We expect to use the cumulative effect transition method. Such method provides that upon applying the new standard, the cumulative effect from prior periods is recognized in our consolidated balance sheet as of the date of adoption, including an adjustment to retained earnings. Prior periods will not be retrospectively adjusted. • We believe that since substantially all of our revenue is contractual, substantially all of our revenue falls within the scope of ASU No. 2014-09, • As discussed above, our hardware and software revenue is generally recognized on a gross basis upon delivery. Third party service contracts, software maintenance and Cloud or software-as-a-service • We believe that the only significant incremental costs incurred to obtain contracts with our clients within the scope of ASU 2014-09, one-year • As discussed above, we hold inventories not available for sale related to certain product sales transactions in which we are warehousing the product and will be deploying the product to our clients’ designated locations subsequent to period-end. • We expect that our disclosures in our notes to our consolidated financial statements related to revenue recognition will be significantly expanded under the new standard. Our analysis and evaluation of the new standard will continue through its effective date in the first quarter of 2018. A substantial amount of work remains to be completed due to the complexity of the new standard, the application of judgment and the requirement for the use of estimates in applying the new standard, as well as the volume of our client portfolio and the related terms and conditions of our contracts that must be reviewed. The quantification of the effects of the new standard, including the items discussed above, is a significant undertaking. Further, we will be required to implement necessary changes in our processes, accounting systems and internal controls in conjunction with applying the new standard.

Return policy for unopened and opened product			We make provisions for estimated product returns that we expect to occur under our return policy based upon historical return rates. Our manufacturers warrant most of the products we market, and it is our policy to request that clients return their defective products directly to the manufacturer for warranty service during the manufacturer’s warranty period. On selected products, and for selected client service reasons, we may accept returns directly from the client and then either credit the client or ship a replacement product. We generally offer a limited 15- to 30-day return policy for unopened products and certain opened products, which are consistent with manufacturers’ terms; however, for some products we may charge restocking fees. Products returned opened are processed and returned to the manufacturer or partner for repair, replacement or credit to us. Subject to some manufacturers’ restrictions, certain products cannot be returned to the manufacturer for warranty processing. We resell most unopened products returned to us. If we accept a return from a client that we cannot return to the partner, we try to mitigate our losses by selling to inventory liquidators, to end users as “previously sold” or “used” products, or through other channels.
