	Description of Business and Summary of Significant Accounting Policies
	Description of Business
	CDW is a Fortune 500 company and a leading provider of integrated information technology (“IT”) solutions to small, medium and large business, government, education and healthcare customers in the U.S. and Canada. The Company's offerings range from discrete hardware and software products to integrated IT solutions such as mobility, security, data center optimization, cloud computing, virtualization and collaboration.
	Basis of Presentation
	The accompanying unaudited interim consolidated financial statements as of June 30, 2014 and for the three and six months ended June 30, 2014 and 2013 (the "consolidated financial statements") have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the "SEC") for interim financial statements. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to such rules and regulations. The consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013 (the "December 31, 2013 financial statements"). The significant accounting policies used in preparing these consolidated financial statements were applied on a basis consistent with those reflected in the December 31, 2013 financial statements. In the opinion of management, the consolidated financial statements contain all adjustments (consisting of a normal, recurring nature) necessary to present fairly the Company's financial position, results of operations, comprehensive income, cash flows and changes in shareholders' equity as of the dates and for the periods indicated. The unaudited consolidated statements of operations for such interim periods reported are not necessarily indicative of results for the full year.
	CDW Corporation ("Parent") was previously owned directly by CDW Holdings LLC ("CDW Holdings"), a company controlled by investment funds affiliated with Madison Dearborn Partners, LLC ("Madison Dearborn") and Providence Equity Partners, L.L.C. ("Providence Equity," and together with Madison Dearborn, the "Sponsors"), certain other co-investors and certain members of CDW management. On July 2, 2013, Parent completed an initial public offering (the "IPO") of its common stock. In connection with the IPO, CDW Holdings distributed all of its shares of Parent's common stock to its members in June 2013 in accordance with the members' respective membership interests and was subsequently dissolved in August 2013. See Note 6 for additional discussion of the IPO.
	Parent has two 100% owned subsidiaries, CDW LLC and CDW Finance Corporation. CDW LLC is an Illinois limited liability company that, together with its 100% owned subsidiaries, holds all material assets and conducts all business activities and operations of the Company. CDW Finance Corporation is a Delaware corporation formed for the sole purpose of acting as co-issuer of certain debt obligations as described in Note 12 and does not hold any material assets or engage in any business activities or operations.
	Throughout these notes, the terms the “Company” and “CDW” refer to Parent and its 100% owned subsidiaries.
	Principles of Consolidation
	The accompanying consolidated financial statements include the accounts of Parent and its 100% owned subsidiaries. All intercompany transactions and accounts are eliminated in consolidation.
	Use of Estimates
	The preparation of consolidated financial statements in accordance with GAAP requires management to make use of certain 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 and the reported amounts of revenue and expenses during the reported periods. The Company bases its estimates on historical experience and on various other assumptions that management believes are reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates.
	The notes to the consolidated financial statements contained in the December 31, 2013 financial statements include an additional discussion of the significant accounting policies and estimates used in the preparation of the Company's consolidated financial statements. There have been no material changes to the Company's significant accounting policies and estimates during the six months ended June 30, 2014.

	Revenue Recognition
	In May 2014, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2014-09, which clarifies the standard for recognizing revenue from contracts with customers. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes the most current revenue recognition guidance. The standard is effective for the Company for the first quarter of 2017 and early adoption is not permitted. The standard allows for either a full retrospective approach or a modified retrospective approach. The Company is currently evaluating the impact that the standard will have on its consolidated financial position, results of operations and cash flows.
	Stock Compensation-Performance Share Awards
	In June 2014, the FASB issued ASU 2014-12, which amended the standard on how to account for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. Under the amended standard, a performance target that could be achieved after the requisite service period is required to be treated as a performance condition that affects the vesting of the award and should not be reflected in estimating the fair value of the award at the grant date. The amendment is effective for the first quarter of 2016 with early adoption permitted. The Company already accounts for performance shares utilizing the method outlined by ASU 2014-12 and is not impacted by the new standard.

	Inventory Financing Agreements
	The Company has entered into agreements with certain financial intermediaries 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 on the accompanying consolidated balance sheets. The Company does not incur any interest expense associated with these agreements as balances are paid when they are due.
	The following table presents the amounts included in accounts payable-inventory financing:
	(in millions)	30-Jun-14		31-Dec-13
	Revolving Loan inventory financing agreement	$	310.2	$	256.1
	Other inventory financing agreements	1.6		0.5
	Accounts payable-inventory financing	$	311.8	$	256.6
	As described in Note 4, in June 2014, the Company entered into a new senior secured asset-based revolving credit facility, which incorporates the previous inventory floorplan sub-facility and, among other changes, removes the $400.0 million limit on the size of the floorplan sub-facility. In connection with the floorplan sub-facility, the Company maintains an inventory financing agreement on an unsecured basis with a financial intermediary to facilitate the purchase of inventory from a certain vendor (the “Revolving Loan inventory financing agreement”). Amounts outstanding under the Revolving Loan inventory financing agreement are unsecured and non-interest bearing.
	The Company also maintains other inventory financing agreements with financial intermediaries to facilitate the purchase of inventory from certain vendors. At June 30, 2014 and December 31, 2013, amounts owed under other inventory financing agreements of $1.6 million and $0.5 million, respectively, were collateralized by the inventory purchased under these financing agreements and a second lien on the related accounts receivable.

	At June 30, 2014, the Company was in compliance with the covenants under its various credit agreements as described below.
	On August 5, 2014, the Company completed the issuance of $600.0 million aggregate principal amount of 6.0% Senior Notes due 2022. See Note 13 for additional information.
	Senior Secured Asset-Based Revolving Credit Facility (“Revolving Loan”)
	At June 30, 2014, the Company had no outstanding borrowings under the Revolving Loan, $2.2 million of undrawn letters of credit and $293.4 million reserved related to the floorplan sub-facility.
	On June 6, 2014, the Company entered into the Revolving Loan, a new five-year $1,250.0 million senior secured asset-based revolving credit facility, with the facility being available to the Company for borrowings, issuance of letters of credit and floorplan financing for certain vendor products. The Revolving Loan matures on June 6, 2019, subject to an acceleration provision discussed below. The Revolving Loan replaces the Company’s previous revolving loan credit facility that was to mature on June 24, 2016. The Revolving Loan (i) increases the overall revolving credit facility capacity available to the Company from $900.0 million to $1,250.0 million, (ii) increases the maximum aggregate amount of increases that may be made to the revolving credit facility from $200.0 million to $300.0 million, (iii) maintains a maturity acceleration provision based upon excess cash availability whereby the Revolving Loan may mature 45 days prior to the final maturity of any then outstanding senior debt if excess cash availability does not exceed the outstanding borrowings of the subject maturing debt at the time of the test plus $150.0 million, (iv) decreases the fee on the unused portion of the revolving credit facility from either 37.5 or 50 basis points, depending on the amount of utilization, to 25 basis points, (v) decreases the applicable interest rate margin by 50 basis points, and (vi) amends the existing inventory floorplan sub-facility as discussed below. In connection with the termination of the previous facility, the Company recorded a loss on extinguishment of long-term debt of $0.4 million in the consolidated statement of operations for the three and six months ended June 30, 2014, representing a write-off of a portion of unamortized deferred financing costs. Fees of $6.4 million related to the Revolving Loan were capitalized as deferred financing costs and are being amortized over the five-year term of the facility on a straight-line basis.
	The Revolving Loan incorporates the previous inventory floorplan sub-facility and related Revolving Loan inventory financing agreement while removing the previous $400.0 million dollar limit on the size of the floorplan sub-facility and the in-transit reserve of 15% of open orders. At June 30, 2014, the financial intermediary reported an outstanding balance of $293.4 million under the Revolving Loan inventory financing agreement. The amount included on the Company's consolidated balance sheet as of June 30, 2014 as accounts payable-inventory financing related to the Revolving Loan inventory financing agreement of $310.2 million includes a $16.8 million accrual for amounts in transit.
	Borrowings under the Revolving Loan bear interest at a variable interest rate plus an applicable margin. The interest rate margin is based on one of two indices, either (i) LIBOR, or (ii) the Alternate Base Rate (“ABR”) with the ABR being the greater of (a) the prime rate, (b) the federal funds effective rate plus 50 basis points or (c) the one-month LIBOR plus 1.00%. The applicable margin varies (1.50% to 2.00% for LIBOR borrowings and 0.50% to 1.00% for ABR borrowings) depending upon average daily excess cash availability under the agreement evidencing the Revolving Loan and is subject to a reduction of 0.25% if, and for as long as, CDW LLC's corporate credit rating from Standard & Poor’s Rating Services is BB or better and the CDW LLC's corporate family rating from Moody’s Investors Service, Inc. is Ba3 or better (in each case with stable or better outlook).
	Under the new Revolving Loan, the Company is permitted to borrow an aggregate amount of $1,250.0 million; however, its ability to borrow under the Revolving Loan is limited by a borrowing base. The borrowing base is (a) the sum of the products of the applicable advance rates on eligible accounts receivable and on eligible inventory as defined in the agreement less (b) any reserves. At June 30, 2014, the borrowing base was $1,263.0 million based on the amount of eligible inventory and accounts receivable balances as of May 31, 2014. The Company could have borrowed up to an additional $954.4 million under the Revolving Loan at June 30, 2014.
	The ability to borrow under the Revolving Loan also remains limited by a minimum liquidity condition, which has been amended to provide that, if excess cash availability is less than the lesser of (i) $125.0 million (up from $90.0 million) and (ii) the greater of (A) 10% of the borrowing base and (B) $100.0 million (up from $60.0 million), the lenders are not required to lend any additional amounts under the Revolving Loan unless the consolidated fixed charge coverage ratio (as described in the agreement evidencing the Revolving Loan) is at least 1.00 to 1.00.
	Senior Secured Term Loan Facility
	On April 29, 2013, the Company entered into a seven-year, $1,350.0 million aggregate principal amount senior secured term loan facility (the "Term Loan"). The Term Loan was issued at a price that was 99.75% of par, which resulted in a discount of $3.4 million. Substantially all of the proceeds from the Term Loan were used to repay the $1,299.5 million outstanding aggregate principal amount of the prior senior secured term loan facility (the "Prior Term Loan Facility"). In connection with this refinancing, the Company recorded a loss on extinguishment of long-term debt of $10.3 million in the consolidated statement of operations for the three and six months ended June 30, 2013. This loss represented a write-off of the remaining unamortized deferred financing costs related to the Prior Term Loan Facility.
	On July 31, 2013, the Company borrowed an additional $190.0 million aggregate principal amount under the Term Loan at a price that was 99.25% of par, which resulted in a discount of $1.4 million. Such proceeds were used to redeem a portion of outstanding Senior Subordinated Notes. The discounts are reported on the consolidated balance sheets as a reduction to the face amount of the Term Loan and are being amortized to interest expense over the term of the related debt. Fees of $6.1 million related to the Term Loan were capitalized as deferred financing costs and are being amortized over the term of the facility using the effective interest method.
	The Company is required to pay quarterly principal installments equal to 0.25% of the original principal amount of the Term Loan, with the remaining principal amount payable on the maturity date of April 29, 2020. The quarterly principal installment payments commenced during the quarter ended June 30, 2013. At June 30, 2014, the outstanding principal amount of the Term Loan was $1,521.2 million, excluding $4.0 million in unamortized discount.
	Borrowings under the Term Loan bear interest at either (a) the alternate base rate ("ABR") plus a margin or (b) LIBOR plus a margin; provided that for the purposes of the Term Loan, LIBOR shall not be less than 1.00% per annum at any time ("LIBOR Floor"). The margin is based upon a net leverage ratio as defined in the agreement governing the Term Loan, ranging from 1.25% to 1.50% for ABR borrowings and 2.25% to 2.50% for LIBOR borrowings. The total net leverage ratio was 3.4 at June 30, 2014. An interest rate of 3.25%, LIBOR Floor plus a 2.25% margin, was in effect during the three-month period ended June 30, 2014.
	The Company has interest rate cap agreements in effect through January 14, 2015 with a combined notional amount of $1,150.0 million. These cap agreements have not been designated as cash flow hedges of interest rate risk for GAAP accounting purposes. Of the total $1,150.0 million notional amount, $500.0 million entitle the Company to payments from the counterparty of the amount, if any, by which three-month LIBOR exceeds 3.5% during the agreement period.

	During the six months ended June 30, 2014, the Company granted 1,232,059 stock options under the 2013 Long-Term Incentive Plan (the "2013 LTIP"). These options vest annually over three years. The Company has elected to use the Black-Scholes option pricing model to estimate the fair value of stock options granted. The Black-Scholes option pricing model incorporates various assumptions including volatility, expected term, risk-free interest rates and dividend yields. The assumptions used to value the stock options granted during the six months ended June 30, 2014 are presented below.
	Assumptions	Six Months Ended June 30, 2014
	Weighted-average grant date fair value	$	7.21
	Weighted-average volatility (1)	30		%
	Weighted-average risk-free rate (2)	1.77		%
	Dividend yield	0.7		%
	Expected term (in years) (3)	6
	-1	Based upon an assessment of the two-year, five-year and implied volatility for the Company’s selected peer group, adjusted for the Company’s leverage.
	-2	Based on a composite U.S. Treasury rate.
	-3	The expected term is calculated using the simplified method. The simplified method defines the expected term as the average of the option’s contractual term and the option’s weighted-average vesting period. The Company utilizes this method as it has limited historical stock option data that is sufficient to derive a reasonable estimate of the expected stock option term.
	The following table sets forth a summary of the Company's restricted stock unit activity for the six months ended June 30, 2014:
		Number of Units		Weighted-Average Grant-Date Fair Value
	Nonvested at January 1, 2014	1,351,572		$	17.04
	Granted	25,809		24.29
	Vested/Settled	(1,410	)	17

	Nonvested at June 30, 2014	1,305,450		$	17.18
	In connection with the Company's 2013 IPO discussed in Note 6, CDW Holdings distributed all of its shares of the Company's common stock to its existing members in accordance with the members' respective membership interests and was subsequently dissolved in August 2013. Common stock received by holders of B Units in connection with the distribution is subject to any vesting provisions previously applicable to the holder's B Units. At the time of the IPO, B Unit holders received 3,798,508 shares of restricted stock with respect to B Units that had not yet vested at the time of the distribution. For the six months ended June 30, 2014, 1,152,782 shares of such restricted stock vested/settled and 4,617 shares were forfeited. As of June 30, 2014, 1,434,634 shares of restricted stock were outstanding.
	During the six months ended June 30, 2014, the Company granted 411,919 performance share units (the "PSUs") under the 2013 LTIP. The percentage of shares that shall vest will range from 0% to 200% of the number of PSUs granted based on the Company's performance against a cumulative adjusted free cash flow measure and cumulative non-GAAP net income per diluted share measure over a three-year performance period. The weighted-average grant-date fair value of the PSUs granted during the period was $24.32 per unit. As of June 30, 2014, 411,919 PSUs were outstanding.
	As of June 30, 2014, the Company estimated there was $35.5 million of total unrecognized compensation expense to be recognized over the next 2.7 years.

	The numerator for both basic and diluted earnings per share is net income. The denominator for basic earnings per share is the weighted average number of common shares outstanding during the period. The dilutive effect of outstanding restricted stock, restricted stock units, stock options and MPK Plan units is reflected in the denominator for diluted earnings per share using the treasury stock method.
	The following is a reconciliation of basic shares to diluted shares:
		Three Months Ended June 30,		Six Months Ended June 30,
	(in millions)	2014	2013	2014	2013
	Weighted-average shares - basic	170.2	145.3	169.9	145.2
	Effect of dilutive securities	2.5	1.4	2.6	1.3
	Weighted-average shares - diluted	172.7	146.7	172.5	146.5
	There was an insignificant amount of potential common shares excluded from diluted earnings per share for the three and six month periods ended June 30, 2014, as their inclusion would have had an anti-dilutive effect. There were no potential common shares excluded from diluted earnings per share for the three and six month periods ended June 30, 2013.

Deferred Compensation Plan	'
	Deferred Compensation Plan
	On March 10, 2010, in connection with the Company’s purchase of $28.5 million principal amount of its outstanding senior subordinated debt, the Company established the Restricted Debt Unit Plan (the “RDU Plan”), an unfunded nonqualified deferred compensation plan. The total number of RDUs that can be granted under the RDU Plan is 28,500. As of June 30, 2014, 28,500 RDUs were outstanding. RDUs that are outstanding vest daily on a pro rata basis over the three-year period from January 1, 2012 (or, if later, the date of hire or the date of a subsequent RDU grant) through December 31, 2014. Participants have no rights to the underlying debt.
	The total amount of compensation available to be paid under the RDU Plan was initially to be based on two components, a principal component and an interest component. The principal component credits the RDU Plan with a notional amount equal to the $28.5 million face value of the Senior Subordinated Notes (the "Debt Pool"), together with certain redemption premium equivalents as noted below. The interest component credits the RDU Plan with amounts equal to the interest that would have been earned on the Debt Pool from March 10, 2010 through maturity on October 12, 2017, except as discussed below. Interest amounts for 2010 and 2011 were deferred until 2012, and thereafter, interest amounts were paid to participants semi-annually on the interest payment due dates.
	The Company used a portion of the IPO proceeds together with incremental borrowings to redeem $324.0 million of the total Senior Subordinated Notes outstanding on August 1, 2013. In connection with the IPO and the partial redemption of the Senior Subordinated Notes, the Company amended the RDU Plan to increase the retentive value of the plan. In accordance with the original terms of the RDU Plan, the principal component of the RDUs converted to a cash-denominated pool upon the redemption of the Senior Subordinated Notes. In addition, the Company added $0.1 million and $1.4 million to the principal component in the three months ended June 30, 2014 and the year ended December 31, 2013, respectively, as redemption premium equivalents in accordance with the terms of the RDU plan. Under the terms of the amended RDU Plan, upon the partial redemption of outstanding Senior Subordinated Notes, the RDUs ceased to accrue the proportionate related interest component credits. The amended RDU Plan provides participants the opportunity to share on a pro rata basis in cash retention pools payable to participants who satisfy certain retention requirements. The aggregate amount of the retention pools was determined to be $15.0 million based upon the amount of interest component credits that would have been allocated to the RDU Plan if the Senior Subordinated Notes had remained outstanding from August 1, 2013 through maturity. The Company recorded a pre-tax charge of $7.5 million in the year ended December 31, 2013 for payment of the first cash retention pool. The second cash retention pool payment is expected to be made to participants who remain employed through December 31, 2015 in the first quarter of 2016. Participants continued to accrue an interest component credit for the proportionate amount of Senior Subordinated Notes still outstanding, payable on the aforementioned semi-annual due dates; such payments, however, will be deducted from the second retention pool payment amount of $7.5 million.
	Unrecognized compensation expense as of June 30, 2014 of approximately $4 million is expected to be recognized through 2014 and approximately $7 million in 2015 through 2017. Payments under the RDU Plan may be impacted if certain significant events occur or circumstances change that would impact the financial condition or structure of the Company.
	Compensation expense of $2.2 million and $2.2 million related to the RDU Plan was recognized for the three months ended June 30, 2014 and 2013, respectively, and $4.4 million and $4.3 million for the six months ended June 30, 2014 and 2013, respectively. At June 30, 2014 and December 31, 2013, the Company had $26.0 million and $21.8 million of liabilities related to the RDU Plan recorded on the consolidated balance sheets, respectively.
	Payment of the principal component of the RDU Plan is expected to be made on October 12, 2017, unless accelerated due to a sale of the Company.

	As of June 30, 2014, the Company does not believe that there is a reasonable possibility that any material loss exceeding the amounts already recognized for these proceedings and matters, if any, has been incurred. However, the ultimate resolutions of these proceedings and matters are inherently unpredictable. As such, the Company's financial condition and results of operations could be adversely affected in any particular period by the unfavorable resolution of one or more of these proceedings or matters.

Segment Information	'
	Segment Information
	Segment information is presented in accordance with a “management approach,” which designates the internal reporting used by the chief operating decision-maker for making decisions and assessing performance as the source of the Company's reportable segments. The Company's segments are organized in a manner consistent with which separate financial information is available and evaluated regularly by the chief operating decision-maker in deciding how to allocate resources and in assessing performance.
	The Company has two reportable segments: Corporate, which is comprised primarily of private sector business customers, and Public, which is comprised of government agencies and education and healthcare institutions. The Company also has two other operating segments, CDW Advanced Services and Canada, which do not meet the reportable segment quantitative thresholds and, accordingly, are combined together as “Other.”
	The Company has centralized logistics and headquarters functions that provide services to the segments. The logistics function includes purchasing, distribution and fulfillment services to support both the Corporate and Public segments. As a result, costs and intercompany charges associated with the logistics function are fully allocated to both of these segments based on a percent of sales. The centralized headquarters function provides services in areas such as accounting, information technology, marketing, legal and coworker services. Headquarters' function costs that are not allocated to the segments are included under the heading of “Headquarters” in the tables below. Depreciation expense is included in Headquarters as it is not allocated among segments or used in measuring segment performance.
	The Company allocates resources to and evaluates performance of its segments based on net sales, income (loss) from operations and Adjusted EBITDA, a non-GAAP measure as defined in the Company's credit agreements. However, the Company has concluded that income (loss) from operations is the more useful measure in terms of discussion of operating results, as it is a GAAP measure.
	Segment information for total assets and capital expenditures is not presented as such information is not used in measuring segment performance or allocating resources between segments.

	Supplemental Guarantor Information
	The Senior Secured Notes, Senior Notes and, prior to being redeemed, the Senior Subordinated Notes are guaranteed by Parent and each of CDW LLC’s direct and indirect, 100% owned, domestic subsidiaries (the “Guarantor Subsidiaries”). All guarantees by Parent and Guarantor Subsidiaries are joint and several, and full and unconditional; provided that each guarantee by the Guarantor Subsidiaries is subject to certain customary release provisions contained in the indentures governing the Senior Secured Notes, Senior Notes and, until satisfied and discharged, the Senior Subordinated Notes. CDW LLC's Canada subsidiary (the “Non-Guarantor Subsidiary”) does not guarantee the debt obligations. CDW LLC and CDW Finance Corporation, as co-issuers, are 100% owned by Parent, and each of the Guarantor Subsidiaries and the Non-Guarantor Subsidiary is 100% owned by CDW LLC. On May 9, 2014, all of the remaining $42.5 million aggregate principal amount of Senior Subordinated Notes was redeemed in full and the indenture governing the Senior Subordinated Notes was satisfied and discharged. See Note 4.
	On August 5, 2014, CDW LLC and CDW Finance Corporation completed the issuance of $600.0 million aggregate principal amount of 6.0% Senior Notes due 2022, which will be guaranteed by Parent and the Guarantor Subsidiaries. The proceeds from this issuance, along with cash on hand, were deposited with the trustee on August 5, 2014 to redeem all of the remaining $325.0 million aggregate principal amount of the Senior Secured Notes and to redeem $234.7 million aggregate principal amount of the Senior Notes. On the same date, the indenture governing the Senior Secured Notes was satisfied and discharged. See Note 13 for additional information.

	Basis of Presentation
	The accompanying unaudited interim consolidated financial statements as of June 30, 2014 and for the three and six months ended June 30, 2014 and 2013 (the "consolidated financial statements") have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the "SEC") for interim financial statements. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to such rules and regulations. The consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013 (the "December 31, 2013 financial statements"). The significant accounting policies used in preparing these consolidated financial statements were applied on a basis consistent with those reflected in the December 31, 2013 financial statements. In the opinion of management, the consolidated financial statements contain all adjustments (consisting of a normal, recurring nature) necessary to present fairly the Company's financial position, results of operations, comprehensive income, cash flows and changes in shareholders' equity as of the dates and for the periods indicated. The unaudited consolidated statements of operations for such interim periods reported are not necessarily indicative of results for the full year.
	CDW Corporation ("Parent") was previously owned directly by CDW Holdings LLC ("CDW Holdings"), a company controlled by investment funds affiliated with Madison Dearborn Partners, LLC ("Madison Dearborn") and Providence Equity Partners, L.L.C. ("Providence Equity," and together with Madison Dearborn, the "Sponsors"), certain other co-investors and certain members of CDW management. On July 2, 2013, Parent completed an initial public offering (the "IPO") of its common stock. In connection with the IPO, CDW Holdings distributed all of its shares of Parent's common stock to its members in June 2013 in accordance with the members' respective membership interests and was subsequently dissolved in August 2013. See Note 6 for additional discussion of the IPO.
	Parent has two 100% owned subsidiaries, CDW LLC and CDW Finance Corporation. CDW LLC is an Illinois limited liability company that, together with its 100% owned subsidiaries, holds all material assets and conducts all business activities and operations of the Company. CDW Finance Corporation is a Delaware corporation formed for the sole purpose of acting as co-issuer of certain debt obligations as described in Note 12 and does not hold any material assets or engage in any business activities or operations.
	Throughout these notes, the terms the “Company” and “CDW” refer to Parent and its 100% owned subsidiaries.
Principles of Consolidation, Policy	'
	Principles of Consolidation
	The accompanying consolidated financial statements include the accounts of Parent and its 100% owned subsidiaries. All intercompany transactions and accounts are eliminated in consolidation.
Use of Estimates, Policy	'
	Use of Estimates
	The preparation of consolidated financial statements in accordance with GAAP requires management to make use of certain 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 and the reported amounts of revenue and expenses during the reported periods. The Company bases its estimates on historical experience and on various other assumptions that management believes are reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates.
	The notes to the consolidated financial statements contained in the December 31, 2013 financial statements include an additional discussion of the significant accounting policies and estimates used in the preparation of the Company's consolidated financial statements. There have been no material changes to the Company's significant accounting policies and estimates during the six months ended June 30, 2014.
