(1)	Ms. Leahy has served as the Principal Executive Officer (“PEO”) for the entirety of 2022, 2021 and 2020 and our other Named Executive Officers for the applicable years were as follows:

	•	2022: Albert J. Miralles; Sona Chawla; Christina M. Corley; and Frederick J. Kulevich.
	•	2021: Albert J. Miralles; Sona Chawla; Christina M. Corley; Elizabeth H. Connelly; and Collin B. Kebo.
	•	2020: Collin B. Kebo; Sona Chawla; Christina M. Corley; Douglas E. Eckrote; Mark C. Chong; and Elizabeth H. Connelly

(2)	Amounts reported in this column represent (i) the total compensation reported in the SCT for the applicable year in the case of Ms. Leahy and (ii) the average of the total compensation reported in the SCT for the applicable year for our other Named Executive Officers reported for the applicable year other than Ms. Leahy.
(3)	To calculate CAP, adjustments were made to the amounts reported in the SCT for the applicable year. The primary difference between the calculation of SCT total compensation and CAP relates to the calculation of stock and option awards:


	SCT CALCULATION IS BASED ON:		COMPANY CAP CALCULATION IS BASED ON:
	Grant date fair value of stock and option awards granted during the year		Year over year change in the fair value of stock and option awards that are unvested as of the end of the year, or vested or were forfeited during the year

A reconciliation of the adjustments for Ms. Leahy and for the average of the other Named Executive Officers is set forth in the table below.

	(a)	Represents Total Compensation as reported in the SCT for the indicated fiscal year. For the other Named Executive Officers, amounts shown represent averages.
	(b)	Represents the grant date fair value of the stock option and stock awards granted during the indicated fiscal year, calculated in accordance with ASC718. See Note 13 to the Audited Financial Statements included in our Form 10-K for the fiscal year ended December 31, 2022 for a discussion of the relevant assumptions used in calculating these amounts.
	(c)	Represents the fair value as of the indicated fiscal year-end of the outstanding and unvested option awards and stock awards granted during such fiscal year, calculated in accordance with the methodology used for financial reporting purposes, including the value associated with the accrual of any dividend equivalent rights.
	(d)	Represents the change in fair value during the indicated fiscal year of each option award and stock award that was granted in a prior fiscal year and that remained outstanding and unvested as of the last day of the indicated fiscal year, calculated in accordance with the methodology used for financial reporting purposes and, for awards subject to performance-based vesting conditions, based on an estimate of the probable outcome of such performance-based vesting conditions as of the last day of the fiscal year, including the value associated with the accrual of any dividend equivalent rights.
	(e)	Represents the fair value at vesting of the option awards and stock awards that were granted and vested during the indicated fiscal year, calculated in accordance with the methodology used for financial reporting purposes, including the value associated with the accrual of any dividend equivalent rights.
	(f)	Represents the change in fair value, measured from the prior fiscal year-end to the vesting date, of each option award and stock award that was granted in a prior fiscal year and which vested during the indicated fiscal year, calculated in accordance with the methodology used for financial reporting purposes, including the value associated with the accrual of any dividend equivalent rights.
	(g)	Represents the fair value as of the last day of the prior fiscal year of the option award and stock awards that were granted in a prior fiscal year and which failed to meet the applicable vesting conditions in the indicated fiscal year, calculated in accordance with the methodology used for financial reporting purposes.

(4)	Pursuant to rules of the SEC, the comparison assumes $100 was invested on December 31, 2019. Historic stock price performance is not necessarily indicative of future stock price performance.
(5)	The TSR Peer Group consists of S&P 500 Information Technology Index.
(6)	The Company determined that adjusted EPS is the most important financial performance measure used to link CAP to Company performance given it impacts the vesting of 50% of the PSUs and also encompasses Non-GAAP operating income performance, the sole financial measure under our SMIP. In addition, we believe that over the long-term, our earnings per share is the most significant driver of CDW’s stock price performance, which impacts the value of equity awards granted to the Named Executive Officers, the largest component of our executive compensation program. Adjusted EPS is defined as non-GAAP net income plus/minus extraordinary, non-recurring items divided by the weighted average common shares outstanding on a diluted basis. For purposes of determining adjusted EPS, non-GAAP net income is defined as net income, adjusted for the items set forth in the Company’s earnings releases which may include, among other items, amortization of intangibles, non-cash equity-based compensation and associated taxes, losses or gains from the extinguishment of debt and acquisition and integration expenses. The amount reported for each reporting year in this table represents the adjusted EPS, as calculated for the first year of the PSU performance cycle that commenced in the applicable reporting year.

2. CAP Versus TSR

As shown in the chart below, the PEO’s and other Named Executive Officers’ CAP amounts align with the Company’s TSR over the three-year period reported in the chart. This is due primarily to the Company’s use of long-term incentives, particularly a significant weighting in stock options, the value of which are tied directly to stock price.

3. CAP Versus Adjusted EPS (Company Selected Measure)

The chart below demonstrates the relationship between CAP amounts for our PEO and our other Named Executive Officers and our adjusted EPS for the applicable fiscal year. Variations in the CAP amounts for our PEO and other Named Executives Officers are due in large part to the significant emphasis the Company places on long-term incentives, the value of which fluctuates most significantly based on the vesting level of our PSU awards and changes in stock price over time. Adjusted EPS is viewed as the most important financial measure to link CAP and Company performance given it impacts the vesting of 50% of the PSUs and it also encompasses Non-GAAP operating income performance, the sole financial measure under our SMIP. In addition, we believe that over the long-term, our earnings per share is the most significant driver of CDW’s stock price performance, which impacts the value of equity awards granted to the PEO and other Named Executive Officers, the largest component of our executive compensation program.
