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 global provider of hardware, software, Cloud and service solutions to business, government, healthcare and educational clients . 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 include hardware, software and services. Our offerings in the remainder of our EMEA segment and in APAC are largely software and select software-related services. Acquisitions 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 (see Note 22). 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 information technology (“IT”) hardware, at the lower of weighted average cost (which approximates cost under the first-in, first-out method) or market. We evaluate inventories for excess, obsolescence or other factors that may render inventories unmarketable at normal margins. Write-downs are recorded so that inventories reflect the approximate net realizable value and take into account contractual provisions with our partners governing price protection, stock rotation and return privileges relating to obsolescence. Because of the large number of transactions and the complexity of managing the price protection and stock rotation process, estimates are made regarding write-downs of the carrying amount of inventories. Additionally, assumptions about future demand, market conditions and decisions by manufacturers/publishers to discontinue certain products or product lines can affect our decision to write down inventories. Inventories not available for sale relate to product sales transactions in which we are warehousing the product and will be deploying the product to clients’ designated locations subsequent to period-end. Additionally, we may perform services on a portion of the product prior to shipment to our clients and will be paid a fee for doing so. Although these product contracts are non-cancelable with customary credit terms beginning the date the inventories are segregated in our warehouse and invoiced to the client and the warranty periods begin on the date of invoice, these transactions do not meet the sales recognition criteria under GAAP. Therefore, we do not record sales and the inventories are classified as inventories not available for sale on our consolidated balance sheet until the product is delivered. If clients remit payment before we deliver product to them, we record the payments received as deferred revenue on our consolidated balance sheet until such time as the product is delivered. 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 software during the application development stage, including capitalized interest, are recorded in property and equipment at cost. External direct costs of materials and services consumed in developing or obtaining internal-use computer software and payroll and payroll-related costs for teammates who are directly associated with and who devote time to internal-use computer software development projects, to the extent of the time spent directly on the project and specific to application development, are capitalized. 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 goodwill impairment test. Otherwise, the two-step goodwill impairment test is not required. The quantitative two-step goodwill impairment review process compares the fair value of the reporting unit in which goodwill resides to its carrying value. The Company has three reporting units, which are the same as our operating segments. Multiple valuation techniques can be used to assess the fair value of the reporting unit. All of these techniques include the use of estimates and assumptions that are inherently uncertain. Changes in these estimates and assumptions could materially affect the determination of fair value or goodwill impairment, or both. 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 Life Customer relationships 2 – 11 years Other 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 capital and retained earnings. The amount recorded as a reduction of paid-in capital is based on the excess of the average original issue price of the shares over par value. The remaining amount is recorded as a reduction of retained earnings. 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 are the primary obligor 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- 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. 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 and software maintenance or subscription products for which we are not the primary obligor. These sales do not meet the criteria for gross sales recognition, and thus are recorded on a net sales recognition basis. As we enter into contracts with third-party service providers or vendors and our clients, we evaluate whether the subsequent sales of such services should be recorded as gross sales or net sales. We determine whether we act as a principal in the transaction and assume the risks and rewards of ownership or if we are simply acting as an agent or broker. Under gross sales recognition, the selling price is recorded in sales and our cost to the third-party service provider or vendor is recorded in costs of goods sold. Under net sales recognition, the cost to the third-party service provider or vendor is recorded as a reduction to sales, resulting in net sales equal to the gross profit on the transaction, and there are no costs of goods sold. 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. 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 $37,317,000, $40,106,000 and $34,900,000 in 2015, 2014 and 2013, 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, 2015. 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 2015. Supplier Risk Purchases from Microsoft, Cisco and Ingram Micro (a distributor) accounted for approximately 27%, 11% and 11%, respectively, of our aggregate purchases in 2015. No other partner accounted for more than 10% of purchases in 2015. Our top five partners as a group for 2015 were Microsoft, Cisco, Ingram Micro, HP and Tech Data (a distributor), and approximately 65% of our total purchases during 2015 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 $27,574,000, $31,214,000 and $29,394,000 was recorded in 2015, 2014 and 2013, 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, multiple awards (i.e., a graded vesting basis). 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) – 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 currency cash balances, are reported as a separate component of non-operating (income) expense in our consolidated statements of operations. Derivative Financial Instruments We enter into forward foreign exchange contracts to mitigate the risk of non-functional currency monetary assets and liabilities on our consolidated financial statements. These forward contracts are not designated as hedge instruments. The fair value of all derivative assets and liabilities are recorded gross in the other current assets and accrued expenses and other current liabilities sections of our consolidated balance sheets. Gains/losses are recorded net in non-operating (income) expense in our consolidated statements of operations. 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 strategies and results of recent operations. If we determine that we would be able to realize our deferred tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. We record uncertain tax positions on the basis of a two-step process whereby (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. Interest and penalties related to unrecognized tax benefits are recognized within the income tax expense line in our consolidated statements of operations. Accrued interest and penalties are included within the related tax liability line in our consolidated balance sheets. 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, 2015 2014 2013 Numerator: Net earnings $ 75,851 $ 75,684 $ 71,021 Denominator: Weighted-average shares used to compute basic EPS 37,984 41,062 43,012 Dilutive potential common shares due to dilutive RSUs, net of tax effect 291 296 277 Weighted-average shares used to compute diluted EPS 38,275 41,358 43,289 Net earnings per share: Basic $ 2.00 $ 1.84 $ 1.65 Diluted $ 1.98 $ 1.83 $ 1.64 In 2015, 2014 and 2013, approximately 1,000, 20,000 and 177,000, 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 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-17, “Balance Sheet Classification of Deferred Taxes,” which simplifies the presentation of deferred income taxes. ASU 2015-17 provides presentation requirements to classify deferred tax assets and liabilities as noncurrent in a classified statement of financial position. The standard is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is permitted for any interim and annual financial statements that have not yet been issued. We early adopted ASU 2015-17 effective December 31, 2015, retrospectively. Adoption resulted in a $13.4 million decrease in total current assets, a $285,000 decrease in total assets and a $285,000 decrease in total liabilities in our consolidated balance sheet at December 31, 2014. Adoption had no impact on our results of operations. In July 2015, the FASB issued ASU No. 2015-11, “Simplifying the Measurement of Inventory.” The standard changes the measurement from lower of cost or market to lower of cost and net realizable value. This standard is effective for reporting periods beginning after December 15, 2016. The guidance shall be applied prospectively, with early adoption permitted as of the beginning of an interim or annual period. The new standard is not expected to have a material effect on our consolidated financial statements. On April 7, 2015, the FASB issued ASU 2015-03, “Interest–Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Cost.” ASU 2015-03 is designed to simplify presentation of debt issuance costs. The standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The amortization of debt issuance costs also shall be reported as interest expense. ASU 2015-03 is effective for the fiscal year beginning after December 15, 2015, including interim reporting periods within that reporting period. The new standard is not expected to have a material effect on our consolidated financial statements. On May 28, 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which amends the existing accounting standards for revenue recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The original effective date for ASU 2014-09 would have required the Company to adopt the new standard beginning in its first quarter of 2017. In July 2015, the FASB voted to amend ASU 2014-09 by approving a one-year deferral of the mandatory effective date as well as providing the option to early adopt the standard on the original effective date. Accordingly, the Company may adopt the standard in either its first quarter of 2017 or 2018. An entity may choose to adopt the new standard either retrospectively or through a cumulative effect adjustment as of the start of the first period for which it applies the new standard. We expect to adopt the standard in the first quarter of 2018 and are in the process of determining the effect that the adoption will have on our consolidated financial statements. We have not yet selected our planned transition approach.

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. During 2015, 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 North America reporting unit (the only reporting unit with a goodwill balance at any period end) below its carrying value. We performed our annual test of goodwill for impairment during the fourth quarter of 2015. The results of the first step of the two-step goodwill impairment test indicated that the fair value of our North America reporting unit, estimated using the market approach, was in excess of the carrying value, and thus we did not perform step two of the impairment test.

Payables and Accruals [Abstract]
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 $250,000,000. Prior to July 2, 2015, the maximum borrowing capacity was $200,000,000. The facility matures on April 26, 2017. Additionally, the facility may be renewed under certain circumstances described in the agreement for successive 12-month periods. Interest does not accrue on accounts payable under this facility provided the accounts payable are paid within stated vendor terms (ranging from 30 to 60 days). We impute interest on the average daily balance outstanding during these stated vendor terms based on our blended incremental borrowing rate during the period under our senior revolving credit facility and our accounts receivable securitization financing facility. Imputed interest of $3,406,000, $2,386,000 and $2,453,000 was recorded in 2015, 2014 and 2013, respectively. If balances are not paid within stated vendor terms, they will accrue interest at prime plus 1.25%. The facility is guaranteed by the Company and each of its material domestic subsidiaries and is secured by a lien on substantially all of the Company’s domestic assets that is of equal priority to the liens securing borrowings under our revolving 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. 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 spread of 1.25% to 2.25%. In addition, we pay a quarterly commitment fee on the unused portion of the facility of 0.25% to 0.45%, and our letter of credit participation fee ranges from 1.25% to 2.25%. Deferred financing fees of $2,300,000 were capitalized in conjunction with the amendment to the revolving facility in 2012. Such fees are being amortized to interest expense over the term of the facility. During 2015, 2014 and 2013, due to availability under our other financing facility, weighted average borrowings under our revolving facility were $21,987,000, $6,634,000 and $17,943,000, respectively. Interest expense associated with the revolving facility was $1,813,000, $1,571,000 and $1,738,000 in 2015, 2014 and 2013, respectively, including the commitment fee and amortization of deferred financing fees. As of December 31, 2015, $350,000,000 was available under the revolving facility. See “Maximum Leverage Ratio” below. Our accounts receivable securitization financing facility (“ABS facility”) has a maximum borrowing capacity of $200,000,000 and matures on June 30, 2017. 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, 2015 and 2014, the SPE owned $849,336,000 and $788,632,000, 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, 2015, qualified receivables were sufficient to permit access to the full $200,000,000 facility amount, of which $89,000,000 was outstanding at December 31, 2015. See “Maximum Leverage Ratio” below. Under our ABS facility, interest is payable monthly, and the floating interest rate applicable at December 31, 2015 was 1.33% per annum, including a 0.90% usage fee on any outstanding balances. In addition, we pay a monthly commitment fee on the unused portion of the facility of 0.40%. Deferred financing fees of $351,000 and $378,000 were capitalized in conjunction with amendments to our ABS facility in 2014 and 2012, respectively. Such fees are being amortized to interest expense over the term of the facility. During the years ended December 31, 2015, 2014 and 2013, 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, was 1.6%, 1.7% and 1.6%, respectively. Weighted average borrowings under our ABS facility in 2015, 2014 and 2013 were $112,101,000, $105,992,000 and $112,959,000, 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, minimum fixed charge and minimum asset coverage ratio requirements 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 imputed interest on our inventory financing facility, (ii) income tax expense (benefit), (iii) depreciation and amortization, (iv) non-cash stock-based compensation and (v) extraordinary or non-recurring non-cash losses or expenses (“adjusted earnings”). The maximum leverage ratio permitted under the agreements is 2.75 times trailing twelve-month adjusted earnings. A significant drop in our adjusted earnings would limit the amount of indebtedness that could be outstanding at the end of any fiscal quarter to a level that would be below our consolidated maximum facility amount. Based on our maximum leverage ratio as of December 31, 2015, our aggregate debt balance that could have been outstanding under our revolving facility and our ABS facility was reduced from the maximum borrowing capacity of $550,000,000 to $469,349,000, of which $89,000,000 was outstanding at December 31, 2015. Capital Lease and Other Financing Obligations Our obligations under capitalized leases are included in long-term debt in the accompanying consolidated balance sheets as of December 31, 2015 and 2014. The current and long-term portions of the obligations are included in the table above. 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 and 2014, amounts owed under other financing agreements of $1,309,000 and $1,852,000, respectively, which are payable in installments through August 2016, are included in our current and long-term debt balances as summarized in the table above.

Leases [Abstract]
Operating Leases	(7) Operating Leases We have non-cancelable operating leases with third parties, primarily for administrative and distribution center space and computer equipment. Our facilities leases generally provide for periodic rent increases and many contain escalation clauses and renewal options. We recognize rent expense on a straight-line basis over the lease term. Rental expense for these third-party operating leases was $14,737,000, $15,493,000 and $15,731,000 in 2015, 2014 and 2013, respectively, and is included in selling and administrative expenses in the accompanying consolidated statements of operations. Future minimum lease payments under non-cancelable operating leases (with initial or remaining lease terms in excess of one year) as of December 31, 2015 are as follows (in thousands): Years Ending December 31, 2016 $ 12,299 2017 11,919 2018 10,433 2019 9,375 2020 7,720 Thereafter 17,723 Total minimum lease payments $ 69,469 Amounts in the table above exclude approximately $1.5 million in each of 2016 and 2017 and approximately $1.6 million in each of 2018 and 2019 in non-cancellable rental income.

Restructuring and Related Activities [Abstract]
Severance and Restructuring Activities	(8) Severance and Restructuring Activities During 2015, 2014 and 2013, we recorded severance expense associated with the elimination of certain positions based on a re-alignment of roles and responsibilities, a continued review of resource needs in North America and significant restructuring activities in EMEA, primarily in the United Kingdom, Germany and France, as we worked to rationalize our selling and administrative expenses in EMEA. The following table details the activity for each of the three years in the period ending December 31, 2015 related to these resource actions, and the outstanding obligations as of December 31, 2015 (in thousands): North America EMEA APAC Consolidated Balances at December 31, 2012 $ 1,249 $ 1,391 $ — $ 2,640 Severance costs, net of adjustments 3,325 9,415 — 12,740 Cash payments (2,864 ) (7,771 ) — (10,635 ) Foreign currency translation adjustments — 212 — 212 Balances at December 31, 2013 1,710 3,247 — 4,957 Severance costs, net of adjustments 971 3,356 106 4,433 Cash payments (1,786 ) (3,475 ) (106 ) (5,367 ) Foreign currency translation adjustments (38 ) (157 ) — (195 ) Balances at December 31, 2014 857 2,971 — 3,828 Severance costs, net of adjustments 1,126 3,781 — 4,907 Cash payments (1,456 ) (3,534 ) — (4,990 ) Foreign currency translation adjustments (22 ) (235 ) — (257 ) Balances at December 31, 2015 $ 505 $ 2,983 $ — $ 3,488 Adjustments were recorded as a reduction to severance and restructuring expense in 2015, 2014 and 2013 of $600,000, $1,023,000 and $292,000, respectively, due to changes in estimates. The remaining outstanding obligations as of December 31, 2015 are expected to be paid during the next 12 months and are therefore included in accrued expenses and other current liabilities.

Stock-Based Compensation	(9) Stock-Based Compensation We recorded the following pre-tax amounts in selling and administrative expenses for stock-based compensation, by operating segment, in the accompanying consolidated financial statements (in thousands): Years Ended December 31, 2015 2014 2013 North America $ 6,648 $ 5,933 $ 5,118 EMEA 1,908 1,547 1,061 APAC 366 270 251 Total Consolidated $ 8,922 $ 7,750 $ 6,430 Company Plan On October 1, 2007, Insight’s Board of Directors approved the 2007 Omnibus Plan (the “2007 Plan”), and the 2007 Plan became effective when it was approved by Insight’s stockholders at the annual meeting on November 12, 2007. On August 12, 2008, the 2007 Plan was amended to clarify certain provisions relating to forfeiture restrictions and grants of discretionary awards to non-employee directors. On May 18, 2011, Insight’s stockholders approved the Company’s Amended 2007 Omnibus Plan (the “Amended 2007 Plan”) to, among other changes, increase the number of shares of common stock authorized to be issued thereunder to a total of 7,250,000 shares. The Amended 2007 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 Amended 2007 Plan, including the power to determine eligibility, the types of awards to be granted, the price and the timing of awards. Under the Amended 2007 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. Teammates, officers and members of the Board of Directors are eligible for awards under the Amended 2007 Plan, and consultants and independent contractors are also eligible if they provide bona fide services that are not related to capital raising or promoting or maintaining a market for the Company’s stock. The Amended 2007 Plan allows for awards of options, stock appreciation rights, restricted stock, RSUs, performance awards as well as grants of cash awards. As of December 31, 2015, of the 7,250,000 shares of stock reserved for awards issued under the Amended 2007 Plan, 3,769,996 shares of stock were available for grant. 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, 2015, total compensation cost related to nonvested RSUs not yet recognized is $14,878,000, which is expected to be recognized over the next 1.27 years on a weighted-average basis. The following table summarizes our RSU activity during 2015: Number Weighted Average Grant Date Fair Value Fair Value Nonvested at the beginning of year 888,967 $ 22.06 Granted 501,809 $ 26.25 Vested, including shares withheld to cover taxes (344,625 ) $ 21.47 $ 9,168,784 (a) Forfeited (94,367 ) $ 23.51 Nonvested at the end of year 951,784 $ 24.35 $ 23,908,814 (b) Expected to vest 874,369 $ 21,964,149 (b) (a) The aggregate fair value of vested RSUs represents the total pre-tax fair value, based on the closing stock price on the day of vesting, which would have been received by holders of RSUs had all such holders sold their underlying shares on that date. The aggregate intrinsic value for RSUs which vested during 2014 and 2013 was $8,371,565 and $11,829,527, respectively. (b) The aggregate fair value of the nonvested RSUs and the RSUs expected to vest represents the total pre-tax fair value, based on our closing stock price of $25.12 as of December 31, 2015, which would have been received by holders of RSUs had all such holders sold their underlying shares on that date. During each of the years in the three-year period ended December 31, 2015, the RSUs that vested for teammates in the United States were net-share settled such that we withheld shares with value equivalent to the teammates’ minimum statutory United States tax obligation for the applicable income and other employment taxes and remitted the equivalent cash amount to the appropriate taxing authorities. The total shares withheld during 2015, 2014 and 2013 of 85,652, 86,732 and 151,521, respectively, were based on the value of the RSUs on their vesting dates as determined by our closing stock price on such dates. For 2015, 2014 and 2013, total payments for the employees’ tax obligations to the taxing authorities were $2,265,000, $2,028,000 and $3,094,000, respectively, and are reflected as a financing activity within the accompanying consolidated statements of cash flows. These net-share settlements had the effect of repurchases of our common stock as they reduced the number of shares that would have otherwise been issued as a result of the vesting and did not represent an expense to us.

Property, Plant and Equipment [Abstract]
Impairment Loss on Assets Held for Sale	(10) Impairment Loss on Assets Held for Sale In November 2014, we relocated our sales and administrative operations that were housed in the property that we own in Bloomingdale, Illinois. The property is classified as a held for sale asset, which is included in other current assets in the accompanying consolidated balance sheets as of December 31, 2015 and 2014. During 2014, our North America operating segment recorded non-cash charges of $5,178,000, consisting of an impairment loss of $4,558,000 and accelerated depreciation of $620,000, to reduce the carrying amount of the related assets to their estimated fair value less costs to sell. The property continues to be marketed for sale, and during 2015, an additional non-cash impairment charge of $800,000 was recorded based on a decline in the estimated fair market value. The estimated fair market value was derived from Level 2 fair value inputs (observable market based inputs or unobservable inputs that are corroborated by market data), which included a current market analysis indicating the price per square foot of previous sale transactions involving comparable property in the Bloomingdale area. The charges are included in selling and administrative expenses in the accompanying consolidated statements of operations for 2015 and 2014.

The undistributed earnings of foreign subsidiaries that are deemed to be indefinitely invested outside of the United States were approximately $88,888,000 at December 31, 2015. 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, 2015 2014 Deferred tax assets: Goodwill and other intangibles $ 42,281 $ 53,869 Net operating losses 17,433 17,439 Foreign tax credits 12,972 13,106 Accruals 7,423 7,311 Accounts receivable 3,749 6,206 Stock-based compensation 3,558 3,137 Inventories 2,667 2,216 Deferred revenue 351 321 Other 2,391 1,307 Gross deferred tax assets 92,825 104,912 Valuation allowances (28,750 ) (28,709 ) Total deferred tax assets 64,075 76,203 Deferred tax liabilities: Property and equipment (1,102 ) (4,933 ) Prepaid expenses (226 ) (205 ) Total deferred tax liabilities (1,328 ) (5,138 ) Net deferred tax assets $ 62,747 $ 71,065 The net non-current deferred tax assets and liabilities are as follows (in thousands): December 31, 2015 2014 Net non-current deferred tax assets $ 62,986 $ 71,720 Net non-current deferred tax liabilities (239 ) (655 ) Net deferred tax assets $ 62,747 $ 71,065 As of December 31, 2015, we have U.S. federal net operating loss carryforwards (“NOLs”) of $485,000 that will expire between 2032 and 2035 and deferred tax assets related to U.S. state NOLs of $620,000 that will expire between 2016 and 2030. We also have NOLs from various non-U.S. jurisdictions of $61,537,000. While the majority of the non-U.S. NOLs have no expiration date, $3,001,000 will expire between 2016 and 2022. 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, 2015 and 2014, our valuation allowances totaled $28,750,000 and $28,709,000, respectively, representing non-U.S. NOLs, foreign depreciation allowances and foreign tax credits. We expect to fully utilize the federal NOLs within the next three years. 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, 2015 2014 Valuation allowances at beginning of year $ 28,709 $ 24,508 Increase in income tax expense 2,944 6,471 Foreign currency translation adjustments (1,743 ) (2,270 ) Other (1,160 ) — Valuation allowances at end of year $ 28,750 $ 28,709 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, 2015 and 2014, we had approximately $3,335,000 and $4,306,000, respectively, of unrecognized tax benefits. Of these amounts, approximately $296,000 and $336,000, 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, 2014 $ 3,970 Additions for tax positions in prior periods 53 Additions for tax positions in current period 483 Subtractions due to foreign currency translation (70 ) Subtractions due to audit settlements and statute expirations (1,397 ) Balance at December 31, 2015 $ 3,039 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 2006 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. jurisdictions. In the United States, federal income tax returns for 2012, 2013, 2014 and 2015 remain open to examination. For U.S. state and local taxes as well as in non-U.S. jurisdictions, the statute of limitations generally varies between three and ten years.

Market Risk Management

Text Block [Abstract]
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 interest rates. We currently do not hedge our interest rate exposure. 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 interest rates since interest rates on the underlying obligations are variable. We had no amounts outstanding under our revolving facility and $89,000,000 outstanding under our ABS facility at December 31, 2015. The interest rate attributable to the borrowings under our ABS facility was 1.33% per annum at December 31, 2015. The change in annual pre-tax earnings from operations resulting from a hypothetical 10% increase or decrease in the applicable interest rate would have been immaterial. 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 foreign exchange rate movements. Remeasurement of these cash balances results in gains/losses that are also reported as a separate component of non-operating (income) expense. We monitor our foreign currency exposure and selectively enter into forward exchange contracts to mitigate risk associated with certain non-functional currency monetary assets and liabilities related to foreign denominated payables, receivables and cash balances. Transaction gains and losses resulting from non-functional currency assets and liabilities are offset by gains and losses on forward contracts in non-operating (income) expense, net in our consolidated statements of operations. The counterparties associated with our foreign exchange forward contracts are large creditworthy commercial banks. The derivatives transacted with these institutions are short in duration and, therefore, we do not consider counterparty concentration and non-performance to be material risks. The Company does not have a significant concentration of credit risk with any single counterparty.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
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 currency assets and liabilities from changes in exchange rate movements. Our non-functional currency assets and liabilities are primarily related to foreign currency denominated payables, receivables, and cash balances. The foreign currency forward contracts, carried at fair value, typically have a maturity of one month or less. We currently enter into approximately four foreign exchange forward contracts per month with an average notional value of $9,750,000 and an average maturity of approximately twelve days. Our derivative financial instruments as of December 31, 2015 were not material. The effect of our derivative financial instruments on our results of operations during the years ended December 31, 2015, 2014 and 2013 were a loss of $942,000, a loss of $205,000 and a gain of $398,000, respectively. These amounts are reported within the net foreign currency exchange (gain) loss line item in our consolidated statements of operations.

Fair Value Measurements

Fair Value Measurements	12 Months Ended
	Dec. 31, 2015
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). Mid-market pricing is used as a practical expedient for fair value measurements. Fair value measurement of an asset or liability must reflect the nonperformance risk of the entity and the counterparty. Therefore, the impact of the counterparty’s creditworthiness when in an asset position and the Company’s creditworthiness when in a liability position has also been factored into the fair value measurement of the derivative instruments and did not have a material impact on the fair value of these derivative instruments. Both the counterparty and the Company are expected to continue to perform under the contractual terms of the instruments. As of December 31, 2015, other than the held for sale asset discussed in Note 10, we have no non-financial assets or liabilities that are measured and recorded at fair value on a recurring basis, and our other financial assets or liabilities generally consist of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses and other current liabilities. The estimated fair values of our cash and cash equivalents approximate their carrying values and are determined based on quoted prices in active markets for identical assets (Level 1). The fair values of the other financial assets and liabilities are based on the values that would be received or paid in an orderly transaction between market participants and approximate their carrying values due to their nature and short duration.

Compensation and Retirement Disclosure [Abstract]
Benefit Plans	(15) Benefit Plans We adopted a defined contribution benefit plan (the “Defined Contribution Plan”) for our U.S. teammates which complies with section 401(k) of the Internal Revenue Code. The Company provides a discretionary match to all participants who make 401(k) contributions pursuant to the Defined Contribution Plan. The discretionary match provided to participants is equivalent to 25% of a participant’s pre-tax contributions up to a maximum of 6% of eligible compensation per pay period. Additionally, we offer several defined contribution benefit plans to our teammates outside of the United States. These plans and their related terms vary by country. Total consolidated contribution expense under these plans was $7,190,000, $7,083,000 and $6,923,000 for 2015, 2014 and 2013, respectively.

The following table summarizes the shares of our common stock that we repurchased on the open market under these repurchase programs, in thousands, except per share amounts: Year Total Number Average Price Approximate Dollar 2015 3,300 $ 27.83 $ 91,843 2014 2,140 23.54 50,383 2013 3,000 19.26 57,774 Total 8,440 $ 200,000 All shares repurchased were retired. Subsequent to December 31, 2015, on February 10, 2016, we announced that our Board of Directors had authorized the repurchase of up to $50,000,000 of our common stock. Any share repurchases will be made on the open market, subject to Rule 10b-18 or in privately negotiated transactions, through 10b5-1 plans or otherwise, at management’s discretion. The amount of shares purchased and the timing of the purchases will be based on market conditions, working capital requirements, general business conditions and other factors. We intend to retire the repurchased shares.

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, 2015, we had approximately $1,451,000 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, 2015. 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 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 for disclosure. 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 resolution of a legal proceeding. Legal expenses related to defense, negotiations, settlements, rulings and advice of outside legal counsel are expensed as incurred. The Company is not involved in any pending or threatened legal proceedings that it believes could 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. Previous to the sale, for approximately twelve months, 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.

Supplemental Financial Information	(19) Supplemental Financial Information A summary of additions and deductions related to the allowance for doubtful accounts receivable for 2015, 2014 and 2013 follows (in thousands): Balance at Beginning of Year Additions Deductions Balance at End of Year Allowance for doubtful accounts receivable: Year ended December 31, 2015 $ 19,336 $ 6,761 $ (14,225 ) $ 11,872 Year ended December 31, 2014 $ 19,908 $ 4,409 $ (4,981 ) $ 19,336 Year ended December 31, 2013 $ 18,905 $ 4,696 $ (3,693 ) $ 19,908 During 2015, we undertook a project to analyze our older accounts receivable to attempt further collection action, or where appropriate, to write off such accounts as uncollectible. 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. The reduction of the reserve during 2015 related to these actions had no effect on our results of operations.

Segment and Geographic Information	(21) Segment and Geographic Information We operate in three reportable geographic operating segments: North America; EMEA; and APAC. Our offerings in North America and select countries in EMEA include IT hardware, software and services. Our offerings in the remainder of our EMEA segment and in APAC are largely software and select software-related services. Net sales by product or service type for North America, EMEA and APAC were as follows (in thousands): North America Years Ended December 31, Sales Mix 2015 2014 2013 Hardware $ 2,336,788 $ 2,175,397 $ 2,130,006 Software 1,231,269 1,174,234 1,129,114 Services 255,471 213,095 211,640 $ 3,823,528 $ 3,562,726 $ 3,470,760 EMEA Years Ended December 31, Sales Mix 2015 2014 2013 Hardware $ 531,308 $ 572,494 $ 504,006 Software 799,761 930,763 930,903 Services 40,068 36,711 34,265 $ 1,371,137 $ 1,539,968 $ 1,469,174 APAC Years Ended December 31, Sales Mix 2015 2014 2013 Hardware $ 14,333 $ 12,463 $ 6,222 Software 158,046 193,533 191,355 Services 6,046 7,539 6,836 $ 178,425 $ 213,535 $ 204,413 The method for determining what information regarding operating segments, products and services, geographic areas of operation and major clients to report is based upon the “management approach,” or the way that management organizes the operating segments within a company, for which separate financial information is evaluated regularly by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources. 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 2015, 2014 or 2013. 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.

Business Combinations [Abstract]
Acquisition	(22) Acquisition 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. 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. The purchase price was allocated using the information currently available. Further information regarding items such as deferred tax amounts and liabilities assumed could lead to an adjustment of the purchase price allocation. Goodwill acquired approximated $29,938,000, which was recorded in our North America operating segment. 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 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 the October 1, 2015 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business We are a Fortune 500-ranked global provider of hardware, software, Cloud and service solutions to business, government, healthcare and educational clients . 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 include hardware, software and services. Our offerings in the remainder of our EMEA segment and in APAC are largely software and select software-related services. Acquisitions 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 (see Note 22).
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 information technology (“IT”) hardware, at the lower of weighted average cost (which approximates cost under the first-in, first-out method) or market. We evaluate inventories for excess, obsolescence or other factors that may render inventories unmarketable at normal margins. Write-downs are recorded so that inventories reflect the approximate net realizable value and take into account contractual provisions with our partners governing price protection, stock rotation and return privileges relating to obsolescence. Because of the large number of transactions and the complexity of managing the price protection and stock rotation process, estimates are made regarding write-downs of the carrying amount of inventories. Additionally, assumptions about future demand, market conditions and decisions by manufacturers/publishers to discontinue certain products or product lines can affect our decision to write down inventories. Inventories not available for sale relate to product sales transactions in which we are warehousing the product and will be deploying the product to clients’ designated locations subsequent to period-end. Additionally, we may perform services on a portion of the product prior to shipment to our clients and will be paid a fee for doing so. Although these product contracts are non-cancelable with customary credit terms beginning the date the inventories are segregated in our warehouse and invoiced to the client and the warranty periods begin on the date of invoice, these transactions do not meet the sales recognition criteria under GAAP. Therefore, we do not record sales and the inventories are classified as inventories not available for sale on our consolidated balance sheet until the product is delivered. If clients remit payment before we deliver product to them, we record the payments received as deferred revenue on our consolidated balance sheet until such time as the product is delivered.
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 software during the application development stage, including capitalized interest, are recorded in property and equipment at cost. External direct costs of materials and services consumed in developing or obtaining internal-use computer software and payroll and payroll-related costs for teammates who are directly associated with and who devote time to internal-use computer software development projects, to the extent of the time spent directly on the project and specific to application development, are capitalized. 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 goodwill impairment test. Otherwise, the two-step goodwill impairment test is not required. The quantitative two-step goodwill impairment review process compares the fair value of the reporting unit in which goodwill resides to its carrying value. The Company has three reporting units, which are the same as our operating segments. Multiple valuation techniques can be used to assess the fair value of the reporting unit. All of these techniques include the use of estimates and assumptions that are inherently uncertain. Changes in these estimates and assumptions could materially affect the determination of fair value or goodwill impairment, or both.
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 Life Customer relationships 2 – 11 years Other 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 capital and retained earnings. The amount recorded as a reduction of paid-in capital is based on the excess of the average original issue price of the shares over par value. The remaining amount is recorded as a reduction of retained earnings.
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 are the primary obligor 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- 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. 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 and software maintenance or subscription products for which we are not the primary obligor. These sales do not meet the criteria for gross sales recognition, and thus are recorded on a net sales recognition basis. As we enter into contracts with third-party service providers or vendors and our clients, we evaluate whether the subsequent sales of such services should be recorded as gross sales or net sales. We determine whether we act as a principal in the transaction and assume the risks and rewards of ownership or if we are simply acting as an agent or broker. Under gross sales recognition, the selling price is recorded in sales and our cost to the third-party service provider or vendor is recorded in costs of goods sold. Under net sales recognition, the cost to the third-party service provider or vendor is recorded as a reduction to sales, resulting in net sales equal to the gross profit on the transaction, and there are no costs of goods sold. 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. 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 $37,317,000, $40,106,000 and $34,900,000 in 2015, 2014 and 2013, 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, 2015. 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 2015. Supplier Risk Purchases from Microsoft, Cisco and Ingram Micro (a distributor) accounted for approximately 27%, 11% and 11%, respectively, of our aggregate purchases in 2015. No other partner accounted for more than 10% of purchases in 2015. Our top five partners as a group for 2015 were Microsoft, Cisco, Ingram Micro, HP and Tech Data (a distributor), and approximately 65% of our total purchases during 2015 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 $27,574,000, $31,214,000 and $29,394,000 was recorded in 2015, 2014 and 2013, 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, multiple awards (i.e., a graded vesting basis).
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) – 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 currency cash balances, are reported as a separate component of non-operating (income) expense in our consolidated statements of operations.
Derivative Financial Instruments	Derivative Financial Instruments We enter into forward foreign exchange contracts to mitigate the risk of non-functional currency monetary assets and liabilities on our consolidated financial statements. These forward contracts are not designated as hedge instruments. The fair value of all derivative assets and liabilities are recorded gross in the other current assets and accrued expenses and other current liabilities sections of our consolidated balance sheets. Gains/losses are recorded net in non-operating (income) expense in our consolidated statements of operations.
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 strategies and results of recent operations. If we determine that we would be able to realize our deferred tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. We record uncertain tax positions on the basis of a two-step process whereby (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. Interest and penalties related to unrecognized tax benefits are recognized within the income tax expense line in our consolidated statements of operations. Accrued interest and penalties are included within the related tax liability line in our consolidated balance sheets.
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, 2015 2014 2013 Numerator: Net earnings $ 75,851 $ 75,684 $ 71,021 Denominator: Weighted-average shares used to compute basic EPS 37,984 41,062 43,012 Dilutive potential common shares due to dilutive RSUs, net of tax effect 291 296 277 Weighted-average shares used to compute diluted EPS 38,275 41,358 43,289 Net earnings per share: Basic $ 2.00 $ 1.84 $ 1.65 Diluted $ 1.98 $ 1.83 $ 1.64 In 2015, 2014 and 2013, approximately 1,000, 20,000 and 177,000, 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 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-17, “Balance Sheet Classification of Deferred Taxes,” which simplifies the presentation of deferred income taxes. ASU 2015-17 provides presentation requirements to classify deferred tax assets and liabilities as noncurrent in a classified statement of financial position. The standard is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is permitted for any interim and annual financial statements that have not yet been issued. We early adopted ASU 2015-17 effective December 31, 2015, retrospectively. Adoption resulted in a $13.4 million decrease in total current assets, a $285,000 decrease in total assets and a $285,000 decrease in total liabilities in our consolidated balance sheet at December 31, 2014. Adoption had no impact on our results of operations. In July 2015, the FASB issued ASU No. 2015-11, “Simplifying the Measurement of Inventory.” The standard changes the measurement from lower of cost or market to lower of cost and net realizable value. This standard is effective for reporting periods beginning after December 15, 2016. The guidance shall be applied prospectively, with early adoption permitted as of the beginning of an interim or annual period. The new standard is not expected to have a material effect on our consolidated financial statements. On April 7, 2015, the FASB issued ASU 2015-03, “Interest–Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Cost.” ASU 2015-03 is designed to simplify presentation of debt issuance costs. The standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The amortization of debt issuance costs also shall be reported as interest expense. ASU 2015-03 is effective for the fiscal year beginning after December 15, 2015, including interim reporting periods within that reporting period. The new standard is not expected to have a material effect on our consolidated financial statements. On May 28, 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which amends the existing accounting standards for revenue recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The original effective date for ASU 2014-09 would have required the Company to adopt the new standard beginning in its first quarter of 2017. In July 2015, the FASB voted to amend ASU 2014-09 by approving a one-year deferral of the mandatory effective date as well as providing the option to early adopt the standard on the original effective date. Accordingly, the Company may adopt the standard in either its first quarter of 2017 or 2018. An entity may choose to adopt the new standard either retrospectively or through a cumulative effect adjustment as of the start of the first period for which it applies the new standard. We expect to adopt the standard in the first quarter of 2018 and are in the process of determining the effect that the adoption will have on our consolidated financial statements. We have not yet selected our planned transition approach.

Acquisition, net of cash acquired			$ 44,221,000
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.
