CDW CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1.		Summary of Significant Accounting Policies

		CDW Corporation (collectively with its subsidiaries, “CDW” or the “Company”) is a leading provider of multi-branded information technology products and services in the United States and Canada. We focus on meeting the technology needs of our customers in business, government, and education through our extensive offering of products from leading brands and a variety of value-added services.

		Basis of Presentation

		The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America. Such principles were applied on a basis consistent with those reflected in our Annual Report on Form 10-K for the year ended December 31, 2006 (“2006 Form 10-K”) and documents incorporated therein as filed with the Securities and Exchange Commission, except as disclosed in Note 2, “Recently Adopted and Newly Issued Accounting Standards.” The accompanying financial data should be read in conjunction with the notes to consolidated financial statements contained in the 2006 Form 10-K and documents incorporated therein. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly our financial position as of March 31, 2007 and December 31, 2006, the results of operations for the three month periods ended March 31, 2007 and 2006, the cash flows for the three month periods ended March 31, 2007 and 2006, and the changes in shareholders’ equity for the three month period ended March 31, 2007. The unaudited consolidated statements of income for such interim periods are not necessarily indicative of results for the full year.

		Use of Estimates

		The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America 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 financial statements and the reported amounts of revenues and expenses during the reported periods. We base our estimates on historical experience and on various other assumptions that we believe 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. See the audited consolidated financial statements and notes thereto included in the 2006 Form 10-K for an additional discussion of the most significant accounting policies and estimates used in the preparation of our financial statements.

		Reclassifications

		Certain reclassifications have been made to the prior year financial statements to conform to the current year presentation.

2.		Recently Adopted and Newly Issued Accounting Standards

		FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes – an Interpretation of FASB Statement 109” (“FIN 48”)

		Effective January 1, 2007, we adopted FIN 48. See Note 4, “Income Taxes,” for further information on the adoption of FIN 48.

		Emerging Issues Task Force (“EITF”) No. 06-3, “How Taxes Collected from Customers and Remitted to Governmental Authorities Should Be Presented in the Income Statement (That is, Gross versus Net Presentation)” (“EITF 06-3”)

		In June 2006, the EITF reached a consensus on EITF 06-3, which became effective for us on January 1, 2007. The EITF consensus was that the presentation of taxes on either a gross or net basis is an accounting policy decision that requires disclosure. Sales tax amounts collected from customers and remitted to governmental authorities are presented on a net basis in our income statement. The adoption of EITF 06-3 had no impact on our financial statements.

		Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS 157”)

		In September 2006, the Financial Accounting Standards Board (“FASB”) issued SFAS 157. SFAS 157 defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. SFAS 157 applies where other accounting pronouncements require or permit fair value measurements; it does not require any new fair value measurements. The effects of adopting SFAS 157 will be determined by the types of instruments carried at fair value in our financial statements at the time of adoption as well as the method utilized to determine their fair values prior to adoption. SFAS 157 is effective for fiscal years beginning after November 15, 2007. We are currently evaluating the impact SFAS 157 will have on our financial statements.

		Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities, Including an Amendment of FASB Statement No. 115” (“SFAS 159”)

		In February 2007, the FASB issued SFAS 159. SFAS 159 permits entities to choose to measure certain financial assets and liabilities at fair value that are otherwise not permitted to be accounted for at fair value under generally accepted accounting principles (the “fair value option”). Election of the fair value option is made on an instrument-by-instrument basis and is irrevocable. At the adoption date, unrealized gains and losses on financial assets and liabilities for which the fair value option is elected would be reported as a cumulative adjustment to beginning retained earnings and all subsequent changes in fair value would be recorded as unrealized gains and losses in earnings. SFAS 159 is effective for fiscal years beginning after November 15, 2007. We are currently evaluating the impact SFAS 159 will have on our financial statements.

3.		Share-Based Compensation

		For the three months ended March 31, 2007 and 2006, the Company recognized $1.7 million and $4.2 million, respectively, in share-based compensation expense (pre-tax). In the first quarter of 2007, we performed an evaluation of the forfeiture rate used to calculate share-based compensation expense and adjusted the rate based on our experience in 2006. As a result, share-based compensation for the three months ended March 31, 2007 was reduced by approximately $1.5 million.

		As of March 31, 2007, there was $27.0 million of unrecognized compensation cost related to

		nonvested share-based compensation awards which is expected to be recognized over a weighted-average period of 3.64 years.

4.		Income Taxes

		Effective January 1, 2007, we adopted FIN 48. FIN 48 prescribes a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 also provides guidance on derecognition of income tax assets and liabilities, financial statement classification and disclosure, and accounting for related interest and penalties.

		In connection with adopting FIN 48, we have reviewed our recent income tax return filings and related workpapers, results from the examination of our tax returns and the items subject to examination to determine the extent and amount of any uncertain tax positions taken. The most recent IRS examination was for the years 2003 and 2004. In that examination, the tax treatment of one item was adjusted; the filing positions taken with respect to this item in 2005 and 2006 are consistent with the results of the final examination. Currently, only the 2005 and 2006 tax years are open to audit by the IRS. The Company has been subject to audit by several states. As of March 31, 2007, there are no on-going state income tax audits. The results of previous state income tax audits resulted in immaterial adjustments to the tax reflected on our returns. While some of these audits involved significant (though not necessarily material) issues such as whether certain of our entities were required to file income taxes with a given state for certain years, the positions taken have been supported and sustained. In addition, we do not have any significant intercompany transactions with our sole international affiliate, CDW Canada. Therefore, as of March 31, 2007, we do not have any material reserves for income taxes and there is no material impact on our financial statements from the adoption of FIN 48. In addition, we did not have any material unrecognized tax benefits at the date of adoption of FIN 48 and do not have any as of March 31, 2007.

		It will be our policy going forward to record any income tax related interest income or expense and penalties as components of income tax expense.

5.		Marketable Securities

		Estimated fair values of marketable securities are based on quoted market prices.

		The following table summarizes our investments in marketable securities at March 31, 2007 (in thousands):


			Gross
			Unrealized
	Estimated		Holding					Amortized
Security Type	Fair Value		Gains		Losses			Cost
Available-for-sale:
State and municipal bonds	$	239,330	$	-	$	-		$	239,330

Total available-for-sale		239,330		-		-			239,330


Held-to-maturity:
U.S. Government and Government agency securities		85,397		-		(72	)		85,469

Total held-to-maturity		85,397		-		(72	)		85,469

Total marketable securities	$	324,727	$	-	$	(72	)	$	324,799

The following table presents the gross unrealized losses and fair values of our investments in marketable securities, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position as of March 31, 2007 (in thousands):


	Less Than 12 Months				12 Months or Greater					Total
			Gross				Gross					Gross
			Unrealized				Unrealized					Unrealized
Security Type	Fair Value		Losses		Fair Value		Losses			Fair Value		Losses
U.S Government and Government agency securities	$	-	$	-	$	35,397	$	(72	)	$	35,397	$	(72	)

Total	$	-	$	-	$	35,397	$	(72	)	$	35,397	$	(72	)

Because the Company believes that unrealized losses on fixed income securities are primarily attributable to changes in interest rates, and because the Company has the ability and intent to hold these investments until a recovery of fair value, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired as of March 31, 2007.

Net unrealized holding losses on available-for-sale securities are determined by specific identification and are included in accumulated other comprehensive income, which is reflected as a separate component of shareholders’ equity.

The following table summarizes the maturities of our fixed income securities as of March 31, 2007 (in thousands):


	Estimated		Amortized
	Fair Value		Cost
Due in one year or less	$	294,727	$	294,799
Due in greater than one year		30,000		30,000

Total investments in marketable securities	$	324,727	$	324,799

		As of March 31, 2007, all of the marketable securities that are due after one year have maturity dates prior to March 31, 2009.

6.		Financing Arrangements

		We have an aggregate $70.0 million available pursuant to two $35.0 million unsecured lines of credit with two financial institutions. One line of credit expires in June 2007, at which time we intend to renew the line. The other line does not have a fixed expiration date. Borrowings under the first credit facility bear interest at the prime rate less 2.5%, LIBOR plus 0.45% or the federal funds rate plus 0.5%, as determined by the Company. Borrowings under the second credit facility bear interest at the prime rate less 2.5%, LIBOR plus 0.45% or the federal funds rate plus 0.45%, as determined by the Company. The Company does not incur any facility fees associated with either line of credit. At March 31, 2007, there were no borrowings under either of the credit facilities.

		We have entered into security agreements with certain financial institutions in order to facilitate the purchase of inventory from various suppliers under certain terms and conditions. The agreements allow for a maximum credit line of $160.0 million collateralized by the inventory purchases financed by the financial institutions and certain other assets. We do not incur any interest expenses associated with these agreements, as we pay the balances when they are due. All amounts owed the financial institutions are included in trade accounts payable.

7.		Earnings Per Share

		At March 31, 2007, we had 78,748,711 outstanding common shares. We have granted options to purchase common shares to the directors and coworkers of the Company under several stock option plans. These options have a dilutive effect on the calculation of earnings per share. The following table is a reconciliation of the numerators and denominators of the basic and diluted earnings per share computations as required by Statement of Financial Accounting Standards No. 128, “Earnings Per Share” (in thousands, except per share amounts):


	Three Months Ended March 31,
	2007		2006
Basic earnings per share:
Income available to common shareholders (numerator)	$	76,780	$	61,678

Weighted-average common shares outstanding (denominator)		78,606		80,004

Basic earnings per share	$	0.98	$	0.77


Diluted earnings per share:
Income available to common shareholders (numerator)	$	76,780	$	61,678

Weighted-average common shares outstanding		78,606		80,004
Effect of dilutive securities:
Options on common stock		1,618		1,969

Total common shares and dilutive securities (denominator)		80,224		81,973

Diluted earnings per share	$	0.96	$	0.75

Additional options to purchase common shares were outstanding during the three month periods ended March 31, 2007 and 2006 but were not included in the computation of diluted earnings per share because they were antidilutive in that either: 1) the exercise price of the options were greater than the average market price of common shares during the respective periods or 2) the deemed per share proceeds under the treasury stock method (the sum of the option exercise price, if applicable, any future compensation expense under Statement of Financial Accounting Standards No. 123R, “Share-Based Payment,” and any related “windfall” tax benefits) for the options on a per share basis exceeded the average market price of common shares during the respective periods. The following table summarizes the weighted-average number, and the weighted-average exercise price, of those options which were excluded from the calculations:


	Three Months Ended March 31,
	2007		2006
Weighted-average number of options (in 000’s)		1,741		2,089
Weighted-average exercise price	$	63.06	$	62.36

8.		Share Repurchase Programs

		Since 1998, we have repurchased a total of 17.8 million shares of our common stock at a total cost of $893.0 million under various share repurchase programs authorized by our Board of Directors. In April 2006, our Board of Directors authorized a share repurchase program of up to 5.0 million shares of our common stock. Share repurchases may be made from time to time in both open market and private transactions, as conditions warrant. This program is expected to remain in effect through April 2008, unless earlier terminated by the Board or completed.

		During the three month period ended March 31, 2007, we repurchased 0.3 million shares of our common stock for $16.1 million. During the three month period ended March 31, 2006, we repurchased 2.2 million shares of our common stock for $127.9 million.

		As of March 31, 2007, 2.9 million shares remained available for repurchase under our current program. Repurchased shares are held in treasury pending use for general corporate purposes, including issuances under various stock plans.

9.		Segment Information

		We have three operating segments: corporate sector, which is primarily comprised of business customers; public sector, which is comprised of federal, state and local government entities, educational institutions, and healthcare institutions; and Berbee, a segment resulting from the Berbee acquisition in October 2006, which provides advanced technology solutions. In accordance with Statement of Financial Accounting Standards No. 131, “Disclosure about Segments of an Enterprise and Related Information,” the internal organization that is used by management for making operating decisions and assessing performance is the source of our reportable segments.

		The accounting policies of the segments are the same as those described in Note 1, “Summary of Significant Accounting Policies.” We allocate resources to and evaluate performance of our segments based on both sales and operating income.

		The following tables present information about our reportable segments (in thousands):


	Three Months Ended March 31, 2007
	Corporate		Public				Headquarters /
	Sector		Sector		Berbee		Other			Consolidated
Net sales	$	1,219,041	$	497,396	$	142,681	$	-		$	1,859,118


Income (loss) from operations	$	97,236	$	25,223	$	5,204	$	(9,708	)	$	117,955


Net interest income and other expense											3,959


Income before income taxes										$	121,914


Total assets	$	531,414	$	270,997	$	302,999	$	971,802		$	2,077,212


	Three Months Ended March 31, 2006
	Corporate		Public				Headquarters /
	Sector		Sector		Berbee		Other			Consolidated
Net sales	$	1,150,184	$	438,445	$	-	$	-		$	1,588,629


Income (loss) from operations	$	89,298	$	14,703	$	-	$	(9,755	)	$	94,246


Net interest income and other expense											4,245


Income before income taxes										$	98,491


Total assets	$	559,669	$	242,193	$	-	$	927,132		$	1,728,994

Our assets are primarily managed by our headquarters functions, including the majority of all cash, cash equivalents, and marketable securities, inventory, and property and equipment. As a result, capital expenditures and related depreciation are immaterial for the operating segments. The operating segments’ assets consist principally of accounts receivable, and, for the Berbee segment specifically, goodwill and other intangible assets.

No single customer accounted for more than 10% of net sales in the three month periods ended March 31, 2007 or 2006. During the three month period ended March 31, 2007, approximately

		2% of our net sales were to customers outside of the continental United States, primarily in Canada.

10.		Contingencies

		On September 9, 2003, CDW completed the purchase of certain assets of Bridgeport Holdings, Inc., Micro Warehouse, Inc., Micro Warehouse, Inc. of Ohio, and Micro Warehouse Gov/Ed, Inc. (collectively, “Micro Warehouse”). On September 10, 2003, Micro Warehouse filed voluntary petitions for relief under chapter 11 of title 11 of the United States Code in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”). The Bankruptcy Court confirmed a plan of distribution with respect to Micro Warehouse which became effective on October 14, 2004. On March 3, 2005, the Bridgeport Holdings, Inc. Liquidating Trust (the “Liquidating Trust”) filed a civil action in the Bankruptcy Court entitled Bridgeport Holdings Liquidating Trust, Inc. vs. CDW Corporation and CDW SAC, Inc. alleging that CDW did not pay reasonably equivalent value for the assets it acquired from Micro Warehouse and seeking to have CDW’s “purchase of Micro Warehouse” set aside and an amount of damages, to be determined at trial, paid to it. On February 1, 2007, CDW entered into a settlement agreement (the “Settlement Agreement”) to resolve the above referenced action pursuant to which CDW agreed to pay $25 million to the Liquidating Trust in return for a full release and complete dismissal of the litigation, with prejudice. While CDW believed it had good defenses to the claims by the Liquidating Trust, it agreed to settle the case in order to avoid the substantial costs and uncertainties involved with further litigation. The Settlement Agreement represents the compromise of a disputed claim and does not constitute an admission of liability on behalf of CDW. An order approving the Settlement Agreement was entered by the Bankruptcy Court on February 21, 2007. That order became final and nonappealable on March 5, 2007. On March 12, 2007, CDW paid the settlement amount and the Bankruptcy Court dismissed the litigation with prejudice.

		From time to time, customers of CDW file voluntary petitions for reorganization under the United States bankruptcy laws. In such cases, certain pre-petition payments received by CDW could be considered preference items and subject to return to the bankruptcy administrator. CDW believes that the final resolution of any such pending preference items will not have a material adverse effect on its financial condition.

		In addition, CDW is party to legal proceedings that arise from time to time, both with respect to specific transactions and in the ordinary course of our business. CDW is also subject to various audits, including by federal, state and local tax authorities, by various government agencies relating to sales under certain government contracts and by vendors relating to vendor incentive programs.

		We do not believe that any current audit or pending or threatened litigation will have a material adverse effect on our financial condition. Litigation and audits, however, involve uncertainties and it is possible that the eventual outcome of litigation or audits could adversely affect our results of operations for a particular period.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited consolidated financial statements and the notes thereto.

Overview

CDW Corporation (collectively with its subsidiaries, “CDW” or the “Company”) is a leading provider of multi-branded information technology products and services in the United States and Canada. We focus on meeting the technology needs of our customers in business, government, and education through our extensive offering of products from leading brands and a variety of value-added services.

For financial reporting purposes, we have three operating segments: corporate sector, which is primarily comprised of business customers; public sector, which is comprised of federal, state and local government entities, educational institutions, and healthcare institutions; and Berbee, a segment resulting from our acquisition of Berbee Information Networks Corporation (“Berbee”) in October 2006, which provides advanced information technology solutions. See Note 9, “Segment Information,” to the Consolidated Financial Statements for more information on our operating segments.

CDW management monitors a number of financial and non-financial measures and ratios on a daily, weekly, and monthly basis in order to track the progress of the business and make adjustments as necessary. We believe that the most important of these measures and ratios include daily sales, by business segment and total company, gross margin, number of orders shipped per day, number of orders shipped complete per day, inventory balance, aging, and turnover, cash, cash equivalents, and marketable securities balance, accounts receivable balance and aging, accounts receivable days sales outstanding, operating expenses, operating margin, and coworker turnover. We also monitor certain measures and ratios specifically for the Berbee operating segment, such as realized bill rates and utilization of engineers and consultants. The measures and ratios are compared to standards or objectives set by management, so that actions can be taken, as necessary, in order to achieve the standards and objectives.

In Item 7 (“Management’s Discussion and Analysis of Financial Condition and Results of Operations”) of our Annual Report on Form 10-K for the year ended December 31, 2006 (“2006 Form 10-K”), which was filed with the Securities and Exchange Commission on March 1, 2007, we included a discussion of the most significant accounting policies and estimates used in the preparation of our financial statements. There has been no material change in the policies and estimates used by us in the preparation of our financial statements since the filing of the 2006 Form 10-K.

Recently Adopted and Newly Issued Accounting Standards

Effective January 1, 2007, we adopted FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes – an Interpretation of FASB Statement 109” (“FIN 48”). See Note 4, “Income Taxes,” to the Consolidated Financial Statements for further information on the adoption of FIN 48.

In June 2006, the Emerging Issues Task Force (“EITF”) reached a consensus on EITF No. 06-3, “How Taxes Collected from Customers and Remitted to Governmental Authorities Should Be Presented in the Income Statement (That is, Gross versus Net Presentation)” (“EITF 06-3”), which became effective for us on January 1, 2007. The EITF consensus was that the presentation of taxes on either a gross or net basis is an accounting policy decision that requires disclosure. Sales tax amounts collected from customers and remitted to governmental authorities are presented on a net basis in our income statement. The adoption of EITF 06-3 had no impact on our financial statements.

In September 2006, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS 157”). SFAS 157 defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. SFAS 157 applies where other accounting pronouncements require or permit fair value measurements; it does not require any new fair value measurements. The effects of adopting SFAS 157 will be determined by the types of instruments carried at fair value in our financial statements at the time of adoption as well as the method utilized to determine their fair values prior to adoption. SFAS 157 is effective for fiscal years beginning after November 15, 2007. We are currently evaluating the impact SFAS 157 will have on our financial statements.

In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities, Including an Amendment of FASB Statement No. 115” (“SFAS 159”). SFAS 159 permits entities to choose to measure certain financial assets and liabilities at fair value that are otherwise not permitted to be accounted for at fair value under generally accepted accounting principles (the “fair value option”). Election of the fair value option is made on an instrument-by-instrument basis and is irrevocable. At the adoption date, unrealized gains and losses on financial assets and liabilities for which the fair value option is elected would be reported as a cumulative adjustment to beginning retained earnings and all subsequent changes in fair value would be recorded as unrealized gains and losses in earnings. SFAS 159 is effective for fiscal years beginning after November 15, 2007. We are currently evaluating the impact SFAS 159 will have on our financial statements.

Results Of Operations

We completed the acquisition of Berbee in October 2006. As such, the results of operations discussed in this section, including in the four tables presented below, include Berbee activity for the three month period ended March 31, 2007, but not for the three month period ended March 31, 2006.

Three Month Period Ended March 31, 2007 Compared to Three Month Period Ended March 31, 2006

Net sales in the first quarter of 2007 increased 17.0% to $1.859 billion, compared to $1.589 billion in the first quarter of 2006. Results for the first quarter of 2007 included sales made by Berbee, which was acquired in October 2006. Sales of notebook computers and accessories, desktop computers and servers, data storage devices, netcomm products, add-on boards/memory, and input devices each increased more than 10% in the first quarter of 2007 over the first quarter of 2006. Corporate sector segment sales increased 6.0% to $1.219 billion in the first quarter of 2007 from $1.150 billion in the first quarter of 2006, and comprised 65.6% of our total net sales for the quarter. Public sector segment sales increased 13.4% to $497.4 million in the first quarter of 2007 from $438.4 million in the first quarter of 2006, and comprised 26.7% of our total net sales for the quarter. Berbee generated sales of $142.7 million in the first quarter of 2007, and comprised 7.7% of our total net sales for the quarter. Compared to the corporate sector and public sector segments, Berbee’s business model is more project oriented, which can result in a greater degree of variability in sales from period to period.

Gross profit increased 18.7% to $301.3 million in the first quarter of 2007, compared to $253.9 million in the first quarter of 2006. As a percentage of net sales, gross profit was 16.2% in the first quarter of 2007, compared to 16.0% in the first quarter of 2006. The increase in the gross profit margin was primarily due to an increased level of vendor incentives, increased commission revenue, and the inclusion of Berbee, as Berbee’s business model incorporates a higher service component that generally results in higher gross margin. The positive impact from these items was partially offset by a lower amount of cooperative advertising funds classified as a reduction of cost of sales and a slightly lower product margin.

Our objective for gross profit as a percentage of net sales is between 15.5% and 16.2%. This revised objective has been raised from the previous range of 15.25% to 16.0% to reflect recent performance. The gross profit margin depends on various factors, including vendor incentive and inventory price protection programs, cooperative advertising funds classified as a reduction of cost of sales, product mix, including third party services, net service contract revenue, commission revenue, pricing strategies, market conditions, and other factors, any of which could result in changes in gross margins from recent experience.

Selling and administrative expenses increased 19.8% in the first quarter of 2007 to $154.2 million, compared to $128.7 million in the first quarter of 2006. The primary factors that impacted selling and administrative expenses were:

	•		The inclusion of the Berbee segment operating expenses in the first quarter of 2007, as a result of the acquisition in October 2006.

	•		Increased payroll costs, as a result of the continued investment in our sales force. Our sales force increased to 2,662 coworkers at March 31, 2007, compared to 2,128 coworkers at March 31, 2006.

As a percentage of net sales, selling and administrative expenses were 8.3% in the first quarter of 2007, compared to 8.1% in the first quarter of 2006.

Advertising expense was $29.2 million in the first quarter of 2007, compared to $30.9 million in the same period of 2006. As a percentage of net sales, advertising expense was 1.6% in the first quarter of 2007, compared to 2.0% in the first quarter of 2006. Advertising expense was slightly lower in the first quarter of 2007 due to a lower amount of cooperative advertising funds classified as a reduction of cost of sales.

Consolidated operating income was $118.0 million in the first quarter of 2007, an increase of 25.2% from $94.2 million in the first quarter of 2006. Consolidated operating income as a percentage

of net sales increased to 6.3% in the first quarter of 2007, compared to 5.9% in the first quarter of 2006. Corporate sector segment operating income was $97.2 million in the first quarter of 2007, an increase of 8.9% from $89.3 million in the first quarter of 2006. The increase in corporate sector segment operating income was primarily due to an increase in sales, partially offset by increased payroll costs as a result of the investment in selling resources. Public sector segment operating income was $25.2 million in the first quarter of 2007, an increase of 71.6% from $14.7 million in the first quarter of 2006. The increase in public sector segment operating income was primarily due to an increase in sales and gross margin. Berbee operating income was $5.2 million in the first quarter of 2007. Headquarters expenses were flat at $9.7 million in both the first quarter of 2007 and the first quarter of 2006.

Our objective for operating income as a percentage of net sales is between 6.0% and 6.4%. This revised objective has been raised from the previous range of 5.8% to 6.3% to reflect recent performance.

The effective income tax rate, expressed as a percentage of income before income taxes, was 37.0% in the first quarter of 2007 compared to 37.4% in the first quarter of 2006. We currently estimate that our effective tax rate will be approximately 38.0% for future quarters of 2007.

Net income in the first quarter of 2007 was $76.8 million, a 24.5% increase from $61.7 million in the first quarter of 2006. Diluted earnings per share were $0.96 in the first quarter of 2007, an increase of 28.0% from $0.75 in the first quarter of 2006.

Seasonality

Sales in our corporate sector segment, which primarily serves business customers, have not historically experienced significant seasonality throughout the year. In contrast, sales in our public sector segment have historically been higher in the third quarter than in other quarters due to the buying patterns of federal government and education customers. If sales to federal government and education customers increase as a percentage of overall sales, the Company as a whole may experience increased seasonality in future periods.

Legal Proceedings

For a description of certain legal proceedings, see Item 1 of Part II of this Form 10-Q.

Liquidity and Capital Resources

Working Capital

We have historically financed our operations and capital expenditures primarily through cash flows from operations. At March 31, 2007, we had cash, cash equivalents, and current marketable securities of $480.2 million, representing an increase of $128.6 million in cash, cash equivalents, and current marketable securities from December 31, 2006. Our working capital increased $76.4 million, to $1.097 billion at March 31, 2007 from $1.020 billion at December 31, 2006. The increase in working capital was primarily due to the increase in cash, cash equivalents, and current marketable securities, partially offset by an increase in accounts payable.

We have an aggregate $70.0 million available pursuant to two $35.0 million unsecured lines of credit with two financial institutions. One line of credit expires in June 2007, at which time we intend to renew the line. The other line does not have a fixed expiration date. Borrowings under the first credit facility bear interest at the prime rate less 2.5%, LIBOR plus 0.5% or the federal funds rate plus 0.5%, as determined by the Company. Borrowings under the second credit facility bear interest at the prime rate less 2.5%, LIBOR plus 0.45% or the federal funds rate plus 0.45%, as determined by the Company. The Company does not incur any facility fees associated with either line of credit. At March 31, 2007, there were no borrowings under either of the credit facilities.

We have entered into security agreements with certain financial institutions in order to facilitate the purchase of inventory from various suppliers under certain terms and conditions. The agreements allow for a maximum credit line of $160.0 million collateralized by the inventory purchases financed by the financial institutions and certain other assets. We do not incur any interest expenses associated with these agreements, as we pay the balances when they are due. All amounts owed the financial institutions are included in trade accounts payable.

Since 1998, we have repurchased a total of 17.8 million shares of our common stock at a total cost of $893.0 million under various share repurchase programs authorized by our Board of Directors. In April 2006, our Board of Directors authorized a share repurchase program of up to 5.0 million shares of our common stock. Share repurchases may be made from time to time in both open market and private transactions, as conditions warrant. This program is expected to remain in effect through April 2008, unless earlier terminated by the Board or completed.

During the three month period ended March 31, 2007, we repurchased 0.3 million shares of our common stock for $16.1 million. During the three month period ended March 31, 2006, we repurchased 2.217 million shares of our common stock for $127.9 million.

As of March 31, 2007, 2.9 million shares remained available for repurchase under our current program. Repurchased shares are held in treasury pending use for general corporate purposes, including issuances under various stock plans.

Capital expenditures in the first quarter of 2007 were $13.8 million, primarily for improvements to our information technology systems. Total capital expenditures for 2007 are expected to be approximately $55 million to $60 million. Our internally generated cash flow has been sufficient to fund our capital expenditures and we believe this will continue.

Our current and anticipated uses of our cash, cash equivalents and marketable securities are to fund growth in working capital and capital expenditures necessary to support future growth in sales, our share repurchase programs, potential dividends, and possible expansion through acquisitions. We believe that the funds held in cash, cash equivalents, and marketable securities, and funds available under the credit facilities, will be sufficient to fund our working capital and cash requirements for the foreseeable future.

Cash Flows for the Three Month Period Ended March 31, 2007

Net cash provided by operating activities was $154.5 million in the three month period ended March 31, 2007. The primary factors that affected our cash flow from operations were net income and an increase in accounts payable. The increase in accounts payable positively impacted cash flows by $52.2 million due to the timing of our normal cycle of payments at the end of the period.

Net cash used in investing activities for the three month period ended March 31, 2007 was $99.8 million, including $193.3 million provided by redemptions and sales of marketable securities, offset by $274.5 million to purchase marketable securities and $13.8 million used for capital expenditures. In addition, we made a final working capital adjustment payment of $4.7 million in the first quarter of 2007 related to the October 2006 acquisition of Berbee.

Net cash used in financing activities for the three month period ended March 31, 2007 was $17.4 million. The primary factor that affected our cash flow from financing activities was the repurchase of 0.3 million shares of our common stock at a total cost of $16.1 million.

There has been no material change from the information provided in Item 7A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2006.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15(b) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Company’s management carried out an evaluation, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the last fiscal quarter. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of March 31, 2007, the Company’s disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company (including its consolidated subsidiaries) in the reports the Company files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms.

Changes in Internal Control Over Financial Reporting

There was no change in the Company’s internal control over financial reporting that occurred during the Company’s fiscal quarter ended March 31, 2007 that materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Part II. Other Information

Item 1. Legal Proceedings

On September 9, 2003, CDW completed the purchase of certain assets of Bridgeport Holdings, Inc., Micro Warehouse, Inc., Micro Warehouse, Inc. of Ohio, and Micro Warehouse Gov/Ed, Inc. (collectively, “Micro Warehouse”). On September 10, 2003, Micro Warehouse filed voluntary petitions for relief under chapter 11 of title 11 of the United States Code in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”). The Bankruptcy Court confirmed a plan of distribution with respect to Micro Warehouse which became effective on October 14, 2004. On March 3, 2005, the Bridgeport Holdings, Inc. Liquidating Trust (the “Liquidating Trust”) filed a civil action in the Bankruptcy Court entitled Bridgeport Holdings Liquidating Trust, Inc. vs. CDW Corporation and CDW SAC, Inc. alleging that CDW did not pay reasonably equivalent value for the assets it acquired from Micro Warehouse and seeking to have CDW’s “purchase of Micro Warehouse” set aside and an amount of damages, to be determined at trial, paid to it. On February 1, 2007, CDW entered into a settlement agreement (the “Settlement Agreement”) to resolve the above referenced action pursuant to which CDW agreed to pay $25 million to the Liquidating Trust in return for a full release and complete dismissal of the litigation, with prejudice. While CDW believed it had good defenses to the claims by the Liquidating Trust, it agreed to settle the case in order to avoid the substantial costs and uncertainties involved with further litigation. The Settlement Agreement represents the compromise of a disputed claim and does not constitute an admission of liability on behalf of CDW. An order approving the Settlement Agreement was entered by the Bankruptcy Court on February 21, 2007. That order became final and nonappealable on March 5, 2007. On March 12, 2007, CDW paid the settlement amount and the Bankruptcy Court dismissed the litigation with prejudice.

From time to time, customers of CDW file voluntary petitions for reorganization under the United States bankruptcy laws. In such cases, certain pre-petition payments received by CDW could be

considered preference items and subject to return to the bankruptcy administrator. CDW believes that the final resolution of any such pending preference items will not have a material adverse effect on its financial condition.

In addition, CDW is party to legal proceedings that arise from time to time, both with respect to specific transactions and in the ordinary course of our business. CDW is also subject to various audits, including by federal, state and local tax authorities, by various government agencies relating to sales under certain government contracts and by vendors relating to vendor incentive programs.

We do not believe that any current audit or pending or threatened litigation will have a material adverse effect on our financial condition. Litigation and audits, however, involve uncertainties and it is possible that the eventual outcome of litigation or audits could adversely affect our results of operations for a particular period.

Item 1A. Risk Factors

There has been no material change from the risk factors described in Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2006.
