Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Recently Issued Accounting Standards	1. Basis of Presentation and Recently Issued Accounting Standards We are a Fortune 500 global IT provider helping businesses of all sizes – from small and medium sized firms to worldwide enterprises, governments, schools and health care organizations – define, architect, implement and manage Intelligent Technology Solutions TM Operating Segment Geography North America United States and Canada EMEA Europe, Middle East and Africa APAC Asia-Pacific Our offerings in North America and select countries in EMEA and APAC include hardware, software and services. Our offerings in the remainder of our EMEA and APAC segments are largely software and select software-related services. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly our financial position as of September 30, 2017, our results of operations for the three and nine months ended September 30, 2017 and 2016 and our cash flows for the nine months ended September 30, 2017 and 2016. The consolidated balance sheet as of December 31, 2016 was derived from the audited consolidated balance sheet at such date. The accompanying unaudited consolidated financial statements and notes have been prepared in accordance with the rules and regulations promulgated by the Securities and Exchange Commission and consequently do not include all of the disclosures normally required by United States generally accepted accounting principles (“GAAP”). The results of operations for interim periods are not necessarily indicative of results for the full year, due in part to the seasonal nature of our business. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the related notes thereto, in our Annual Report on Form 10-K The consolidated financial statements include the accounts of Insight Enterprises, Inc. and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Additionally, these estimates and assumptions affect the reported amounts of net sales and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, we evaluate our estimates, including those related to sales recognition, anticipated achievement levels under partner funding programs, assumptions related to stock-based compensation valuation, allowances for doubtful accounts, valuation of inventories, litigation-related obligations, valuation allowances for deferred tax assets and impairment of long-lived assets, including purchased intangibles and goodwill, if indicators of potential impairment exist. Recently Issued Accounting Standards In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, In July 2015, the FASB issued ASU No. 2015-11, On May 28, 2014, the FASB issued ASU No. 2014-09, We will adopt the standard on January 1, 2018, and expect to utilize the modified retrospective transition method. While we are still finalizing our accounting policies under the new standard and are in the process of quantifying the cumulative effect adjustment from prior periods that will be recognized in our consolidated balance sheet as of the date of adoption as an adjustment to retained earnings, to date we have concluded: • The accounting for inventories not available for sale related to certain product net sales transactions in which we are warehousing the product and will be deploying the product to our clients’ designated locations subsequent to period-end • The accounting for renewals of certain software term licenses will change to delay revenue recognition until the beginning of the renewal period. • In sales transactions for certain security software products that are sold with accompanying third-party delivered software maintenance, we believe the updates provided by the publisher are not separately identifiable from the software. We will change to record both the software license and the accompanying software maintenance on a net basis, as the agent in the arrangement. Under current guidance, we bifurcate the sale of the software license from the sale of the maintenance contract, record the sale of the software product on a gross basis, as the principal in the arrangement, and record the sale of the software maintenance on a net basis, as an agent in the arrangement. • Sales commissions on contracts with performance periods that exceed one year will be recorded as an asset and amortized to expense over the related contract performance period as opposed to being expensed in the period the transaction is generated. Our analysis and evaluation of the new standard will continue through its effective date in the first quarter of 2018. A substantial amount of work has been completed, and findings and progress to date have been reported to management and the Audit Committee. Although we do not currently expect the changes resulting from the adoption of the new standard to materially affect our results of operations, our conclusions are still being finalized. There have been no other material changes or additions to the recently issued accounting standards as previously reported in Note 1 to our Consolidated Financial Statements in Part II, Item 8 of our Annual Report on Form 10-K

Net Earnings Per Share ("EPS")	Sep. 30, 2017
Earnings Per Share [Abstract]
Net Earnings Per Share ("EPS")	2. Net Earnings Per Share (“EPS”) Basic EPS is computed by dividing net earnings available to common stockholders by the weighted average number of common shares outstanding during each period. Diluted EPS is computed on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding restricted stock units (“RSUs”). A reconciliation of the denominators of the basic and diluted EPS calculations follows (in thousands, except per share data): Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 Numerator: Net earnings $ 22,412 $ 21,635 $ 76,515 $ 63,590 Denominator: Weighted average shares used to compute basic EPS 35,787 35,474 35,718 36,310 Dilutive potential common shares due to dilutive RSUs, net of tax effect 416 316 468 286 Weighted average shares used to compute diluted EPS 36,203 35,790 36,186 36,596 Net earnings per share: Basic $ 0.63 $ 0.61 $ 2.14 $ 1.75 Diluted $ 0.62 $ 0.60 $ 2.11 $ 1.74 For the three and nine months ended September 30, 2017, 36,000 and 48,000, respectively, of our RSUs were not included in the diluted EPS calculations because their inclusion would have been anti-dilutive. These share-based awards could be dilutive in the future. There were 5,000 and 48,000 anti-dilutive RSUs for the three and nine months ended September 30, 2016, respectively.

Debt Disclosure [Abstract]
Debt, Inventory Financing Facility, Capital Leases and Other Financing Obligations	3. Debt, Inventory Financing Facility, Capital Leases and Other Financing Obligations Debt Our long-term debt consists of the following (in thousands): September 30, December 31, 2016 Senior revolving credit facility $ 216,000 $ — Term Loan A (less unamortized debt issuance costs of $936) 167,502 — Accounts receivable securitization financing facility 160,000 39,500 Capital leases and other financing obligations 6,227 1,231 Total 549,729 40,731 Less: current portion of long-term debt (15,344 ) (480 ) Long-term debt $ 534,385 $ 40,251 Our senior revolving credit facility (“revolving facility”) has an aggregate U.S. dollar equivalent maximum borrowing amount of $350,000,000, including a maximum borrowing capacity that may be used for borrowing in certain foreign currencies of $50,000,000, and matures on June 23, 2021. On January 6, 2017, we amended our revolving facility to expand the facility by $175,000,000 in the form of an incremental Term Loan A (“TLA”). Pricing and all other general terms and conditions of the TLA are governed by the existing revolving facility. The TLA requires amortization payments of 5%, 7.5%, 10%, 12.5% and 15% of the original principal balance in years one through five, respectively, to be paid quarterly through March 31, 2021, with the remaining balance of $107,187,500 due at maturity on June 23, 2021. The revolving facility and TLA are guaranteed by the Company’s material domestic subsidiaries and are 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 and the TLA 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 and TLA bear interest, payable quarterly, at a floating rate equal to the prime rate plus a predetermined spread of 0.00% to 0.75% or, at our option, a LIBOR rate plus a pre-determined Our accounts receivable securitization financing facility (the “ABS facility”) has a maximum aggregate borrowing availability of $250,000,000, and matures on June 23, 2019. Interest is payable monthly, and the floating interest rate applicable at September 30, 2017 was 2.14% per annum, including a 0.85% usage fee on any outstanding balances. In addition, we pay a monthly commitment fee on the unused portion of the facility of 0.375%. 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 September 30, 2017, qualified receivables were sufficient to permit access to the full $250,000,000 facility amount, of which $160,000,000 was outstanding. Our consolidated debt balance that can be outstanding at the end of any fiscal quarter under our revolving facility, our TLA and our ABS facility is limited by certain financial covenants, particularly a maximum leverage ratio. The maximum leverage ratio is calculated as aggregate debt outstanding divided by the sum of our trailing twelve month net earnings (loss) plus (i) interest expense, excluding non-cash (iv) non-cash non-recurring non-cash Inventory Financing Facility Our inventory financing facility has a maximum borrowing capacity of $325,000,000, of which $224,072,000 was outstanding at September 30, 2017, and matures on June 23, 2021. If balances are not paid within stated vendor terms, they will accrue interest at prime plus 1.25%. From time to time and at our option, we may request to increase the aggregate amount available under the inventory financing facility by up to an aggregate of $25,000,000, subject to customary conditions. Amounts outstanding under this facility are classified separately as accounts payable - inventory financing facility in the accompanying consolidated balance sheets. Interest does not accrue on advances paid within vendor terms. The inventory financing 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 and each guarantor’s assets. Capital Lease and Other Financing Obligations In March 2016 and May 2017, we entered into capitalized leases with 36-month 12-month non-cash In conjunction with our acquisition of Datalink effective January 6, 2017, we acquired certain obligations associated with Datalink’s financing of the equipment that it leased to its clients. These financing obligations totaled $2,950,000 as of September 30, 2017. The current and long-term portions of our capital lease and other financing obligations are included in the current and long-term portions of long-term debt in the table above and in our consolidated balance sheet as of September 30, 2017.

Income Tax Disclosure [Abstract]
Income Taxes	6. Income Taxes Our effective tax rate for the three and nine months ended September 30, 2017 was 36.8% and 35.6%, respectively. For the three months ended September 30, 2017, our effective tax rate was higher than the United States federal statutory rate of 35.0% due primarily to state income taxes, net of federal benefit, and the disallowance of the loss on the sale of a foreign entity. Additionally, the effect of lower taxes on earnings in foreign jurisdictions was offset partially by losses in certain foreign jurisdictions, resulting in an increase in the valuation allowance for deferred tax assets related to these foreign operating losses. For the nine months ended September 30, 2017, our effective tax rate approximated the United States federal statutory rate of 35.0% due primarily to increases in the rate caused by state income taxes, net of federal benefit, and the disallowance of the loss on the sale of a foreign entity offset by decreases in the rate caused by the recognition of $2,258,000 of tax benefits on the settlement of employee share-based awards during the first nine months of 2017 in accordance with a new accounting standard, which was adopted effective January 1, 2017. See Note 1 for additional information relating to this new accounting standard. Additionally, the effect of lower taxes on earnings in foreign jurisdictions was offset partially by losses in certain foreign jurisdictions, resulting in an increase in the valuation allowance for deferred tax assets related to these foreign operating losses. Our effective tax rate for the three and nine months ended September 30, 2016 was 35.0% and 36.8%, respectively. For the three months ended September 30, 2016, our effective tax rate was equal to the United States federal statutory rate of 35.0%. The decrease in rates resulting from the recognition of certain tax benefits related to the release of reserves for specific uncertain tax positions during the quarter and lower taxes on earnings in foreign jurisdictions fully offset the increase in rates caused by state income taxes, net of federal benefit. For the nine months ended September 30, 2016, our effective tax rate was higher than the United States federal statutory rate of 35.0% due primarily to state income taxes, net of federal benefit, and losses in certain foreign jurisdictions, resulting in an increase in the valuation allowance for deferred tax assets related to these foreign operating losses. As of September 30, 2017 and December 31, 2016, we had approximately $3,877,000 and $2,246,000, respectively, of unrecognized tax benefits. Of these amounts, approximately $276,000 and $195,000, respectively, related to accrued interest. In the future, if recognized, the liability associated with uncertain tax positions would affect our effective tax rate. We do not believe there will be any changes over the next 12 months that would have a material effect on our effective tax rate. Several of our subsidiaries are currently under audit for tax years 2012 through 2015. 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.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	8. Commitments and Contingencies Contractual In the ordinary course of business, we issue performance bonds to secure our performance under certain contracts or state tax requirements. As of September 30, 2017, we had approximately $2,704,000 of performance bonds outstanding. These bonds are issued on our behalf by a surety company on an unsecured basis; however, if the surety company is ever required to pay out under the bonds, we have contractually agreed to reimburse the surety company. Management believes that payments, if any, related to these performance bonds are not probable at September 30, 2017. Accordingly, we have not accrued any liabilities related to such performance bonds in our consolidated financial statements. Employment Contracts and Severance Plans We have employment contracts with, and severance plans covering, certain officers and management teammates under which severance payments would become payable in the event of specified terminations without cause or terminations under certain circumstances after a change in control. In addition, vesting of outstanding nonvested RSUs would accelerate following a change in control. If severance payments under the current employment agreements or plan payments were to become payable, the severance payments would generally range from three to twenty-four months of salary. Indemnifications From time to time, in the ordinary course of business, we enter into contractual arrangements under which we agree to indemnify either our clients or third-party service providers from certain losses incurred relating to services performed on our behalf or for losses arising from defined events, which may include litigation or claims relating to past performance. These arrangements include, but are not limited to, the indemnification of our clients for certain claims arising out of our performance under our sales contracts, the indemnification of our landlords for certain claims arising from our use of leased facilities and the indemnification of the lenders that provide our credit facilities for certain claims arising from their extension of credit to us. Such indemnification obligations may not be subject to maximum loss clauses. Management believes that payments, if any, related to these indemnifications are not probable at September 30, 2017. Accordingly, we have not accrued any liabilities related to such indemnifications in our consolidated financial statements. We have entered into separate indemnification agreements with certain of our executive officers and with each of our directors. These agreements require us, among other requirements, to indemnify such officers and directors against expenses (including attorneys’ fees), judgments and settlements incurred by such individual in connection with any action arising out of such individual’s status or service as our executive officer or director (subject to exceptions such as where the individual failed to act in good faith or in a manner the individual reasonably believed to be in, or not opposed to, the best interests of the Company) and to advance expenses incurred by such individual with respect to which such individual may be entitled to indemnification by us. There are no pending legal proceedings that involve the indemnification of any of the Company’s directors or officers. Contingencies Related to Third-Party Review From time to time, we are subject to potential claims and assessments from third parties. We are also subject to various governmental, client and partner audits. We continually assess whether or not such claims have merit and warrant accrual. Where appropriate, we accrue estimates of anticipated liabilities in the consolidated financial statements. Such estimates are subject to change and may affect our results of operations and our cash flows. Legal Proceedings From time to time, we are party to various legal proceedings arising in the ordinary course of business, including preference payment claims asserted in client bankruptcy proceedings, indemnification claims, claims of alleged infringement of patents, trademarks, copyrights and other intellectual property rights, claims of alleged non-compliance The Company is not involved in any pending or threatened legal proceedings that it believes would reasonably be expected to have a material adverse effect on its business, financial condition or results of operations.

Segment Information	9. Segment Information We operate in three reportable geographic operating segments: North America; EMEA; and APAC. Our offerings in North America and select countries in EMEA and APAC include IT hardware, software and services. Our offerings in the remainder of our EMEA and APAC segments are largely software and select software-related services. Net sales by offering for North America, EMEA and APAC were as follows (in thousands): North America EMEA APAC Three Months Ended September 30, Three Months Ended September 30, Three Months Ended September 30, Sales Mix 2017 2016 2017 2016 2017 2016 Hardware $ 962,214 $ 651,277 $ 137,493 $ 128,214 $ 7,447 $ 4,638 Software 342,601 323,436 163,260 174,180 20,153 22,182 Services 106,264 76,620 11,441 9,338 7,100 2,831 $ 1,411,079 $ 1,051,333 $ 312,194 $ 311,732 $ 34,700 $ 29,651 North America EMEA APAC Nine Months Ended September 30, Nine Months Ended September 30, Nine Months Ended September 30, Sales Mix 2017 2016 2017 2016 2017 2016 Hardware $ 2,476,645 $ 1,801,941 $ 400,362 $ 359,597 $ 18,449 $ 13,728 Software 1,012,725 898,193 552,800 586,332 91,430 106,435 Services 313,973 214,341 35,447 30,871 17,717 6,494 $ 3,803,343 $ 2,914,475 $ 988,609 $ 976,800 $ 127,596 $ 126,657 All significant intercompany transactions are eliminated upon consolidation, and there are no differences between the accounting policies used to measure profit and loss for our segments or on a consolidated basis. Net sales are defined as net sales to external clients. None of our clients exceeded ten percent of consolidated net sales for the three or nine months ended September 30, 2017 or 2016. 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.

Acquisitions	10. Acquisitions Caase.com Effective September 26, 2017, we acquired Caase.com, a Dutch cloud service provider, for a purchase price, net of cash acquired, of approximately $6,038,000, subject to a final working capital adjustment. We believe that this acquisition strengthens our ability to deliver Intelligent Technology Solutions TM The preliminary purchase price was allocated using the information currently available. Further information obtained upon the finalization of the fair value assumptions for identifiable intangible assets acquired and the evaluation of uncertain tax positions could lead to an adjustment of the purchase price allocation. Identified intangible assets and goodwill acquired approximated $2,232,000 and $4,117,000, respectively, which were recorded in our EMEA operating segment. None of the goodwill is tax deductible. We consolidated the results of operations for Caase.com within our EMEA operating segment beginning on the September 26, 2017 effective date of the acquisition. Our historical results would not have been materially affected by the acquisition of Caase.com 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. Datalink On January 6, 2017, we completed our acquisition of Datalink, a leading provider of IT services and enterprise data center solutions based in Eden Prairie, Minnesota, for a cash purchase price of $257,456,000, which included cash and cash equivalents acquired of $76,597,000. We believe that this acquisition strengthened our position as a leading IT solutions provider with deep technical talent delivering data center solutions to clients on premise or in the cloud. The following table summarizes the purchase price and the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition (in thousands): Total purchase price $ 257,456 Fair value of net assets acquired: Current assets $ 238,577 Identifiable intangible assets – see description below 94,500 Property and equipment 5,843 Other assets 17,888 Current liabilities (129,071 ) Long-term liabilities, including deferred taxes (34,421 ) Total fair value of net assets acquired 193,316 Excess purchase price over fair value of net assets acquired (“goodwill”) $ 64,140 Under the acquisition method of accounting, the total purchase price as shown in the table above was allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values. The excess of the purchase price over fair value of net assets acquired was recorded as goodwill. The estimated fair values of current assets and liabilities (other than deferred revenue and related deferred costs) were based upon their historical costs on the date of acquisition due to their short-term nature. The majority of property and equipment were also estimated based upon historical costs as they approximated fair value. Certain long-term assets, including Datalink’s IT system, were written down to the estimated fair value based on the economic benefit expected to be realized from the assets following the acquisition. Deferred revenue acquired represents monies collected prior to January 6, 2017 related to unearned revenues associated with support services to be performed in the future. The estimated fair value of deferred revenue of $65,500,000, which is included in current and long-term liabilities in the table above, was calculated using the adjusted fulfillment cost method as the present value of the costs expected to be incurred by a third party to perform the support services obligations acquired under various customer contracts, plus a reasonable profit associated with the performance effort. The deferred costs acquired represent monies paid prior to January 6, 2017 to purchase third party customer support contracts from manufacturers. The estimated fair value of the deferred costs of $48,029,000, which is included in current and other assets in the table above, was calculated in conjunction with the valuation of deferred revenue discussed above. Identified intangible assets of $94,500,000 consist primarily of customer relationships, the trade name and non-compete The identifiable intangibles resulting from the acquisition are amortized using the straight-line method over the following estimated useful lives: Intangible Assets Estimated Economic Life Customer relationships 10 Years Trade name 1 Year Non-compete 1 Year Amortization expense recognized for the period from the acquisition date through September 30, 2017 was $8,640,000. Goodwill of $64,140,000, which was recorded in our North America operating segment, represents the excess of the purchase price over the estimated fair value assigned to tangible and identifiable intangible assets acquired and liabilities assumed from Datalink. The goodwill is not amortized and will be tested for impairment annually in the fourth quarter of our fiscal year. The addition of the Datalink technical employees to our team and the opportunity to grow our data center solutions business are the primary factors making up the goodwill recognized as part of the transaction. None of the goodwill is tax deductible. The preliminary purchase price was allocated using information available at the time. During the second quarter of 2017, upon analysis of additional information affecting our estimate of the fair value of net assets acquired, we adjusted the purchase price allocation and reduced the goodwill balance by $945,000. During the third quarter of 2017, no further adjustments to the purchase price allocation were made. Further information regarding deferred tax amounts could lead to an additional adjustment of the purchase price allocation upon finalization of the fair value assumptions in the fourth quarter of 2017. We have consolidated the results of operations for Datalink since its acquisition on January 6, 2017. Consolidated net sales and gross profit for the three and nine months ended September 30, 2017 include $134,495,000 and $29,874,000, and $387,218,000 and $89,124,000, respectively, from Datalink. The following table reports pro forma information as if the acquisition of Datalink had been completed at the beginning of the earliest period presented (in thousands, except per share amounts): Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 Net sales As reported $ 1,757,973 $ 1,392,716 $ 4,919,548 $ 4,017,932 Proforma $ 1,757,973 $ 1,544,175 $ 4,923,457 $ 4,472,878 Net earnings As reported $ 22,412 $ 21,635 $ 76,515 $ 63,590 Proforma $ 22,412 $ 20,721 $ 74,461 $ 63,285 Diluted earnings per share As reported $ 0.62 $ 0.60 $ 2.11 $ 1.74 Proforma $ 0.62 $ 0.58 $ 2.06 $ 1.73 Changes in Goodwill Other than the goodwill recorded in conjunction with the acquisitions of Datalink and Caase.com, the only other change in consolidated goodwill as of September 30, 2017 compared to the balance as of December 31, 2016 resulted from foreign currency translation adjustments associated with the goodwill balance in our APAC operating segment.

Recently Issued Accounting Standards	Recently Issued Accounting Standards In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, In July 2015, the FASB issued ASU No. 2015-11, On May 28, 2014, the FASB issued ASU No. 2014-09, We will adopt the standard on January 1, 2018, and expect to utilize the modified retrospective transition method. While we are still finalizing our accounting policies under the new standard and are in the process of quantifying the cumulative effect adjustment from prior periods that will be recognized in our consolidated balance sheet as of the date of adoption as an adjustment to retained earnings, to date we have concluded: • The accounting for inventories not available for sale related to certain product net sales transactions in which we are warehousing the product and will be deploying the product to our clients’ designated locations subsequent to period-end • The accounting for renewals of certain software term licenses will change to delay revenue recognition until the beginning of the renewal period. • In sales transactions for certain security software products that are sold with accompanying third-party delivered software maintenance, we believe the updates provided by the publisher are not separately identifiable from the software. We will change to record both the software license and the accompanying software maintenance on a net basis, as the agent in the arrangement. Under current guidance, we bifurcate the sale of the software license from the sale of the maintenance contract, record the sale of the software product on a gross basis, as the principal in the arrangement, and record the sale of the software maintenance on a net basis, as an agent in the arrangement. • Sales commissions on contracts with performance periods that exceed one year will be recorded as an asset and amortized to expense over the related contract performance period as opposed to being expensed in the period the transaction is generated. Our analysis and evaluation of the new standard will continue through its effective date in the first quarter of 2018. A substantial amount of work has been completed, and findings and progress to date have been reported to management and the Audit Committee. Although we do not currently expect the changes resulting from the adoption of the new standard to materially affect our results of operations, our conclusions are still being finalized. There have been no other material changes or additions to the recently issued accounting standards as previously reported in Note 1 to our Consolidated Financial Statements in Part II, Item 8 of our Annual Report on Form 10-K
