NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1. ORGANIZATION

WESCO International, Inc. ("WESCO International") and its subsidiaries (collectively, “WESCO” or the "Company"), headquartered in Pittsburgh, Pennsylvania, is a leading provider of business-to-business distribution, logistics services and supply chain solutions.

The Company has operating segments that are organized around three strategic business units consisting of Electrical & Electronic Solutions ("EES"), Communications & Security Solutions ("CSS") and Utility & Broadband Solutions ("UBS").

2. ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements of WESCO have been prepared in accordance with Rule 10-01 of Regulation S-X of the Securities and Exchange Commission (the “SEC”). The unaudited condensed consolidated financial information should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in WESCO’s 2020 Annual Report on Form 10-K as filed with the SEC on March 1, 2021. The Condensed Consolidated Balance Sheet at December 31, 2020 was derived from the audited Consolidated Financial Statements as of that date, but does not include all of the disclosures required by accounting principles generally accepted in the United States of America.

The unaudited Condensed Consolidated Balance Sheet as of June 30, 2021, the unaudited Condensed Consolidated Statements of Income (Loss) and Comprehensive Income (Loss), the unaudited Condensed Consolidated Statements of Stockholders' Equity for the three and six months ended June 30, 2021 and 2020, and the unaudited Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2021 and 2020, respectively, in the opinion of management, have been prepared on the same basis as the audited Consolidated Financial Statements and include all adjustments necessary for the fair statement of the results of the interim periods presented herein. All adjustments reflected in the unaudited condensed consolidated financial information are of a normal recurring nature unless indicated. The results for the interim periods presented herein are not necessarily indicative of the results to be expected for the full year.

Prior to the completion of its merger with Anixter International Inc. ("Anixter") on June 22, 2020, as described in Note 4, "Acquisitions and Disposals", WESCO had four operating segments that had been aggregated as one reportable segment. Effective on the date of acquisition, the Company added Anixter as a separate reportable segment for the quarterly period ended June 30, 2020. At the beginning of the third quarter of 2020, the Company identified new operating segments organized around three strategic business units consisting of EES, CSS and UBS. These operating segments are equivalent to the Company's reportable segments. The operating segments in the respective periods were determined in accordance with the manner in which WESCO's chief operating decision maker ("CODM") reviewed financial information during those periods. The financial information used by the CODM to evaluate the performance of the Company's operating segments is disclosed in Note 13, "Business Segments". The applicable comparative financial information reported in the Company's previously issued interim financial statements for the three and six months ended June 30, 2020 has been recast in this Quarterly Report on Form 10-Q to conform to the basis of the new segments.

Reclassifications

For the three and six months ended June 30, 2020, $0.7 million and $0.8 million, respectively, of other non-operating income has been reclassified from "net interest and other" to "other income, net" in the unaudited Condensed Consolidated Statements of Loss and Comprehensive Loss. For the six months ended June 30, 2020, stock-based compensation of $9.5 million and amortization of debt discount and debt issuance costs of $2.1 million have been reclassified from other operating activities in the unaudited Condensed Consolidated Statement of Cash Flows. These reclassifications have been made to conform to the current period presentation.

Change in Estimates

During the second quarter of 2021, the Company established a new corporate brand strategy that will result in migrating certain legacy WESCO sub-brands to a master brand architecture. The Company accounts for the trademarks associated with these sub-brands as intangible assets. As of December 31, 2020, $39.1 million of the trademarks impacted by the master brand strategy had indefinite lives and $9.5 million had remaining estimated useful lives ranging from 3 to 8 years. The Company continually evaluates whether events or circumstances have occurred that would require a change to the estimated useful lives of indefinite-lived and definite lived intangible assets. When such a change is warranted, the remaining carrying amount of the intangible asset is amortized prospectively over the revised remaining useful life. Accordingly, during the second quarter of 2021, the Company changed the estimated useful lives of the trademarks affected by the new corporate brand strategy to coincide with the expected period of time to migrate such sub-brands to the master brand architecture. The Company assigned remaining estimated useful lives to these trademarks, including those that previously had indefinite lives, ranging from less than one year to 5 years. The Company assessed these intangible assets for impairment prior to amortizing them over their revised estimated remaining useful lives. No impairment losses were identified as a result of these tests.

Recently Adopted Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which removes certain exceptions to the general principles of Accounting Standards Codification Topic 740, Income Taxes, and simplifies other aspects of accounting for income taxes. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted in any interim or annual period, with any adjustments reflected as of the beginning of the fiscal year of adoption. The Company adopted this ASU in the first quarter of 2021. The adoption of this guidance did not have a material impact on the consolidated financial statements and notes thereto presented herein.

Recently Issued Accounting Pronouncements

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this Update are effective for all entities as of March 12, 2020 through December 31, 2022. Management is currently evaluating the impact related to the replacement of London Interbank Offered Rate (LIBOR) and whether the Company will elect the adoption of the optional guidance.

Other pronouncements issued by the FASB or other authoritative accounting standards groups with future effective dates are either not applicable or are not expected to be significant to WESCO’s financial position, results of operations or cash flows.

3. REVENUE

(1)    No individual other international country's net sales are material.

(2)    WESCO attributes revenues from external customers to individual countries on the basis of point of sale.

In accordance with certain contractual arrangements, WESCO receives payment from its customers in advance and recognizes such payment as deferred revenue. Revenue for advance payment is recognized when the performance obligation has been satisfied and control has transferred to the customer, which is generally upon shipment. Deferred revenue is usually recognized within a year or less from the date of the customer’s advance payment. At June 30, 2021 and December 31, 2020, $43.0 million and $24.3 million, respectively, of deferred revenue was recorded as a component of other current liabilities in the Condensed Consolidated Balance Sheets.

WESCO’s revenues are adjusted for variable consideration, which includes customer volume rebates, returns, and discounts. WESCO measures variable consideration by estimating expected outcomes using analysis and inputs based upon historical data as well as current and forecasted information. Variable consideration is reviewed by management on a monthly basis and revenue is adjusted accordingly. Variable consideration reduced revenue for the three months ended June 30, 2021 and 2020 by approximately $112.4 million and $31.7 million, respectively, and by approximately $217.8 million and $54.9 million for the six months ended June 30, 2021 and 2020, respectively. As of June 30, 2021 and December 31, 2020, the Company's estimated product return obligation was $39.6 million and $38.9 million, respectively.

Shipping and handling activities are recognized in net sales when they are billed to the customer. WESCO has elected to recognize shipping and handling costs as a fulfillment cost. Shipping and handling costs recorded as a component of selling, general and administrative expenses totaled $62.7 million and $20.9 million for the three months ended June 30, 2021 and 2020, respectively, and $116.0 million and $38.9 million for the six months ended June 30, 2021 and 2020, respectively.

4. ACQUISITIONS AND DISPOSALS

Anixter International Inc.

On June 22, 2020, WESCO completed its acquisition of Anixter, a Delaware corporation. Pursuant to the terms of the Agreement and Plan of Merger, dated January 10, 2020 (the “Merger Agreement”), by and among Anixter, WESCO and Warrior Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of WESCO (“Merger Sub”), Merger Sub was merged with and into Anixter (the “Merger”), with Anixter surviving the Merger and continuing as a wholly owned subsidiary of WESCO. On June 23, 2020, Anixter merged with and into Anixter Inc., with Anixter Inc. surviving to become a wholly owned subsidiary of WESCO.

The Company used the net proceeds from the issuance of senior unsecured notes, borrowings under its revolving credit and accounts receivable securitization facilities, as well as cash on hand, to finance the acquisition of Anixter and related transaction costs.

At the effective time of the Merger, each outstanding share of common stock of Anixter (subject to limited exceptions) was converted into the right to receive (i) $72.82 in cash, (ii) 0.2397 shares of common stock of WESCO, par value $0.01 per share (the “WESCO Common Stock”) and (iii) 0.6356 depositary shares, each representing a 1/1,000th interest in a share of newly issued fixed-rate reset cumulative perpetual preferred stock of WESCO, Series A, with a $25,000 stated amount per whole preferred share and an initial dividend rate equal to 10.625%.

Anixter was a leading distributor of network and security solutions, electrical and electronic solutions, and utility power solutions with locations in over 300 cities across approximately 50 countries, and 2019 annual sales of more than $8 billion. The Merger brought together two companies with highly compatible capabilities and characteristics. The combination of WESCO and Anixter created an enterprise with scale and should afford the Company the opportunity to digitize its business, and expand its services portfolio and supply chain offerings.

Less: Cash acquired	(103,463)
Cash paid for acquisition, net of cash acquired	$	3,707,575

The Merger was accounted for as a business combination with WESCO acquiring Anixter in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations. Under the acquisition method of accounting, the purchase consideration was allocated to the identified assets acquired and liabilities assumed based on their respective acquisition date fair value, with any excess allocated to goodwill. The fair value estimates were based on income, market and cost valuation methods using primarily unobservable inputs developed by management, which are categorized as Level 3 in the fair value hierarchy. Specifically, the fair values of the identified trademark and customer relationship intangible assets were estimated using the relief-from-royalty and multi-period excess earnings methods, respectively. Significant inputs used to value these identifiable intangible assets included projected revenues and expected operating margins, customer attrition rates, discount rates, royalty rates, and applicable income tax rates. The excess purchase consideration recorded to goodwill is not deductible for income tax purposes, and has been assigned to the Company's reportable segments based on their relative fair values, as disclosed in Note 5, "Goodwill and Intangible Assets". The resulting goodwill is primarily attributable to Anixter's workforce, significant cross-selling opportunities in additional geographies, enhanced scale, and other operational efficiencies.

During the second quarter of 2021, the Company finalized its allocation of the purchase consideration to the respective fair values of assets acquired and liabilities assumed in the acquisition of Anixter. As the Company obtained additional information during the measurement period (one year from the acquisition date), it recorded adjustments to its preliminary estimates of fair value, which are presented in the table below. The net impact of these adjustments was an increase to goodwill of $13.4 million in the second quarter of 2021 and $16.4 million since the Company's initial estimate.

6. STOCK-BASED COMPENSATION

WESCO sponsors a stock-based compensation plan. On May 27, 2021, the Company's stockholders approved the WESCO International, Inc. 2021 Omnibus Incentive Plan (the “2021 Plan”). The 2021 Plan is administered by the Compensation Committee of the Company's Board of Directors.

The 2021 Plan was designed to be the successor plan to all prior stock-based compensation plans. Accordingly, no new awards may be granted under the Company’s 1999 Long-Term Incentive Plan, as amended and restated (the “1999 Plan”) or any other prior plan. Awards outstanding under any such prior plans will remain in full force and effect under such plans according to their respective terms. To the extent that any such award is forfeited, terminates, expires or lapses without being exercised, or is settled for cash, the shares subject to such award not delivered will again be available for awards under the 2021 Plan.

The maximum number of shares of the Company’s common stock that may be granted pursuant to awards under the 2021 Plan is 2,150,000, less any shares issued under the 1999 Plan after March 31, 2021 and until the annual stockholders meeting in May 2021. If any award granted under the 2021 Plan is forfeited, terminates, expires or lapses instead of being exercised, or is settled for cash, the shares subject to such award will again be available for grant under the 2021 Plan. Shares delivered by participants or withheld by the Company to pay all or a portion of the exercise price or withholding taxes with respect to stock option or stock appreciation right awards will not again be available for issuance. Shares delivered by participants or withheld by the Company to satisfy applicable tax withholding obligations with respect to a full-value award (i.e., restricted shares or restricted stock units) will again be available for grant under the 2021 Plan.

WESCO’s stock-based employee compensation awards outstanding under the 1999 Plan are comprised of stock-settled stock appreciation rights, restricted stock units and performance-based awards. Compensation cost for all stock-based awards is measured at fair value on the date of grant and compensation cost is recognized, net of estimated forfeitures, over the service period for awards expected to vest. The fair value of stock-settled stock appreciation rights is determined using the Black-Scholes model. The fair value of restricted stock units and performance-based awards with performance conditions is determined by the grant-date closing price of WESCO’s common stock. The forfeiture assumption is based on WESCO’s historical employee behavior that is reviewed on an annual basis. No dividends are assumed. For stock-settled stock appreciation rights that are exercised and for restricted stock units and performance-based awards that vest, shares are issued out of WESCO's outstanding common stock.

Stock-settled stock appreciation rights vest ratably over a three-year period and terminate on the tenth anniversary of the grant date unless terminated sooner under certain conditions. Restricted stock unit awards granted in February 2020 and prior vest based on a minimum time period of three years. The special award described below vests in tranches. Restricted stock units awarded in 2021 vest ratably over a three-year period on each of the first, second and third anniversaries of the grant date. Vesting of performance-based awards is based on a three-year performance period, and the number of shares earned, if any, depends on the attainment of certain performance levels. Outstanding awards would vest upon the consummation of a change in control transaction and performance-based awards would vest at the target level.

On July 2, 2020, a special award of restricted stock units was granted to certain officers of the Company. These awards vest in tranches of 30% on each of the first and second anniversaries of the grant date and 40% on the third anniversary of the grant date, subject, in each case, to continued employment through the applicable anniversary date.

Performance-based awards granted in 2021, 2020 and 2019 were based on two equally-weighted performance measures: the three-year average growth rate of WESCO's net income and the three-year cumulative return on net assets.

During the three and six months ended June 30, 2021 and 2020, WESCO granted the following stock-settled stock appreciation rights, restricted stock units and performance-based awards at the following weighted-average fair values:

	Three Months Ended				Six Months Ended
	June 30, 2021		June 30, 2020		June 30, 2021		June 30, 2020
Stock-settled stock appreciation rights granted	3,398		—		139,592		262,091
Weighted-average fair value	$	38.62	$	—	$	33.19	$	13.86
Restricted stock units granted	6,861		—		307,583		211,450
Weighted-average fair value	$	86.91	$	—	$	77.12	$	48.32
Performance-based awards granted	3,020		—		122,812		158,756
Weighted-average fair value	$	86.91	$	—	$	76.76	$	48.67

The fair value of stock-settled stock appreciation rights was estimated using the following weighted-average assumptions:

	Three Months Ended			Six Months Ended
	June 30, 2021		June 30, 2020	June 30, 2021		June 30, 2020
Risk free interest rate	1.3	%	n/a	0.8	%	1.4	%
Expected life (in years)	7		n/a	7		5
Expected volatility	42	%	n/a	41	%	30	%

The risk-free interest rate is based on the U.S. Treasury Daily Yield Curve as of the grant date. The expected life is based on historical exercise experience and the expected volatility is based on the volatility of the Company's daily stock price over the expected life preceding the grant date of the award.

The following table sets forth a summary of stock-settled stock appreciation rights and related information for the six months ended June 30, 2021:

	Awards	Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (In years)	Aggregate Intrinsic Value (In thousands)
Outstanding at December 31, 2020	2,161,556	$	60.48

Exercisable at June 30, 2021	1,359,501	$	64.73	5.1	$	53,041

For the six months ended June 30, 2021, the aggregate intrinsic value of stock-settled stock appreciation rights exercised during such period was $24.9 million.

Unvested at June 30, 2021	377,908	$	59.35

Vesting of the 377,908 shares of performance-based awards in the table above is dependent upon the achievement of certain performance targets, including half that are dependent upon the three-year average growth rate of WESCO's net income and the other half that are based upon the three-year cumulative return on net assets. These awards are accounted for as awards with performance conditions; compensation cost is recognized over the performance period based upon WESCO's determination of whether it is probable that the performance targets will be achieved.

WESCO recognized $7.2 million and $4.9 million of non-cash stock-based compensation expense, which is included in selling, general and administrative expenses, for the three months ended June 30, 2021 and 2020, respectively. WESCO recognized $13.2 million and $9.5 million of non-cash stock-based compensation expense, which is included in selling, general and administrative expenses, for the six months ended June 30, 2021 and 2020, respectively. As of June 30, 2021, there was $55.3 million of total unrecognized compensation expense related to non-vested stock-based compensation arrangements for all awards previously made of which approximately $14.8 million is expected to be recognized over the remainder of 2021, $23.9 million in 2022, $15.2 million in 2023 and $1.4 million in 2024.

7. EARNINGS PER SHARE

Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding during the periods. Diluted earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average common shares and common share equivalents outstanding during the periods. The dilutive effect of common share equivalents is considered in the diluted earnings per share computation using the treasury stock method, which includes consideration of equity awards.

Accounts Receivable Securitization Facility

On June 1, 2021, WESCO Distribution amended its accounts receivable securitization facility (the “Receivables Facility”) pursuant to the terms and conditions of a Third Amendment to the Fifth Amended and Restated Receivables Purchase Agreement (the “Receivables Amendment”), by and among WESCO Receivables Corp. (“WESCO Receivables”), WESCO Distribution, the various purchaser groups from time to time party thereto and PNC Bank, National Association, as Administrator. The Receivables Amendment amends the amended and restated receivables purchase agreement entered into on June 22, 2020 (the “Receivables Purchase Agreement”). The Receivables Amendment, among other things, increased the purchase limit under the Receivables Purchase Agreement from $1,200 million to $1,300 million, extended the maturity date from June 22, 2023 to June 21, 2024, decreased the LIBOR floor from 0.50% to 0.00% and decreased the interest rate spread from 1.20% to 1.15%. The commitment fee of the Receivables Facility remained unchanged.

Under the Receivables Facility, WESCO sells, on a continuous basis, an undivided interest in all domestic accounts receivable to WESCO Receivables, a wholly owned special purpose entity (the “SPE”). The SPE sells, without recourse, a senior undivided interest in the receivables to financial institutions for cash while maintaining a subordinated undivided interest in the receivables, in the form of overcollateralization. Since WESCO maintains control of the transferred receivables, the transfers do not qualify for “sale” treatment. As a result, the transferred receivables remain on the balance sheet, and WESCO recognizes the related secured borrowing. WESCO has agreed to continue servicing the sold receivables for the third-party conduits and financial institutions at market rates; accordingly, no servicing asset or liability has been recorded.

5.375% Senior Notes due 2021

In November 2013, WESCO Distribution issued $500 million aggregate principal amount of 5.375% Senior Notes due 2021 (the "2021 Notes") through a private offering exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). The 2021 Notes were issued at 100% of par and were governed by an indenture (the “2021 Indenture”) entered into on November 26, 2013 between WESCO International and U.S. Bank National Association, as trustee. The 2021 Notes were unsecured senior obligations of WESCO Distribution and were guaranteed on a senior unsecured basis by WESCO International. The 2021 Notes had a stated interest rate of 5.375% per annum, payable semi-annually in arrears on June 15 and December 15 of each year. The 2021 Notes had a maturity date of December 15, 2021 and were redeemable in whole or in part at any time. The net proceeds of the 2021 Notes were used to prepay a portion of the U.S. sub-facility of the then outstanding term loan due 2019.

Under the terms of a registration rights agreement dated as of November 26, 2013 among WESCO Distribution, WESCO International and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as the representative of the initial purchasers of the 2021 Notes, WESCO Distribution and WESCO International agreed to register under the Securities Act notes having terms identical in all material respects to the 2021 Notes (the “2021 Exchange Notes”) and to make an offer to exchange the 2021 Exchange Notes for the 2021 Notes. WESCO Distribution launched the exchange offer on June 12, 2014 and the exchange offer expired on July 17, 2014.

On December 15, 2020, WESCO Distribution exercised its right to redeem the entire $500 million aggregate principal amount of the 2021 Notes, and U.S. Bank, National Association, as trustee under the 2021 Indenture, issued a notice of redemption to registered holders of the 2021 Notes.

On January 14, 2021, WESCO Distribution redeemed the $500 million aggregate principal amount of the 2021 Notes at a redemption price equal to 100% of the principal amount plus accrued interest to, but not including, January 14, 2021. The redemption of the 2021 Notes was funded with available cash, as well as borrowings under the Company's accounts receivable securitization and revolving credit facilities. The Company recognized a loss of $1.0 million from the redemption of the 2021 Notes resulting from the the write-off of unamortized debt issuance costs, which is recorded as a component of interest expense, net in the Condensed Consolidated Statement of Income and Comprehensive Income for the six months ended June 30, 2021.

5.375% Senior Notes due 2024

In June 2016, WESCO Distribution issued $350 million aggregate principal amount of 5.375% Senior Notes due 2024 (the "2024 Notes") through a private offering exempt from the registration requirements of the Securities Act. The 2024 Notes were issued at 100% of par and are governed by an indenture (the “2024 Indenture”) entered into on June 15, 2016 among WESCO Distribution, as issuer, WESCO International, as parent guarantor, and U.S. Bank National Association, as trustee. The 2024 Notes are unsecured senior obligations of WESCO Distribution and are guaranteed on a senior unsecured basis by WESCO International. The 2024 Notes bear interest at a stated rate of 5.375% per annum, payable semi-annually in arrears on June 15 and December 15 of each year. The 2024 Notes mature on June 15, 2024. The Company used the net proceeds to redeem its 6.0% Convertible Senior Debentures due 2029.

WESCO Distribution launched the exchange offer on December 28, 2016 and the exchange offer expired on January 31, 2017.

On June 2, 2021, WESCO Distribution exercised its right to redeem the entire $350 million aggregate principal amount of the 2024 Notes, and U.S. Bank, National Association, as trustee under the 2024 Indenture, issued a notice of redemption to registered holders of the 2024 Notes. The date fixed for the redemption of the 2024 Notes is July 2, 2021. Accordingly, the 2024 Notes are classified as a component of short-term debt and current portion of long-term debt in the Condensed Consolidated Balance Sheet as of June 30, 2021. The 2024 Notes will be redeemed at a redemption price equal to 101.344% of the principal amount of the 2024 Notes plus accrued interest on the 2024 Notes to, but not including, July 2, 2021.

9. EMPLOYEE BENEFIT PLANS

Defined Contribution Plans

WESCO Distribution sponsors a defined contribution retirement savings plan for the majority of its U.S. employees. The Company matches contributions made by employees at an amount equal to 50% of participants' total monthly contributions up to 6% of eligible compensation. Contributions are made in cash and employees have the option to transfer balances allocated to their accounts into any of the available investment options. The Company may also make, subject to the Board of Directors' approval, a discretionary contribution to the defined contribution retirement savings plan covering U.S. participants if certain predetermined profit levels are attained.

WESCO Distribution Canada LP, a wholly-owned subsidiary of the Company, sponsors a defined contribution plan for certain Canadian employees. The Company makes contributions in amounts ranging from 3% to 5% of participants' eligible compensation based on years of continuous service.

Anixter Inc. sponsors a defined contribution plan covering all of its non-union U.S. employees (the "Anixter Employee Savings Plan"). The employer match for the Anixter Employee Savings Plan is equal to 50% of a participant's contribution up to 5% of the participant's compensation. Anixter Inc. will also make an annual contribution to the Anixter Employee Savings Plan on behalf of each active participant who is hired or rehired on or after July 1, 2015, or is not participating in the Anixter Inc. Pension Plan. The amount of the employer annual contribution is equal to either 2% or 2.5% of the participant’s compensation, as determined by the participant’s years of service. This contribution is in lieu of being eligible for the Anixter Inc. Pension Plan. Certain of Anixter Inc.'s foreign subsidiaries also have defined contribution plans. Contributions to these plans are based upon various levels of employee participation and legal requirements.

WESCO incurred charges of $16.1 million and $3.4 million for the three months ended June 30, 2021 and 2020, respectively, and $32.7 million and $9.1 million for the six months ended June 30, 2021 and 2020, respectively, for all defined contribution plans.

Deferred Compensation Plans

WESCO Distribution sponsors a non-qualified deferred compensation plan (the "WESCO Deferred Compensation Plan") that permits select employees to make pre-tax deferrals of salary and bonus. Employees have the option to transfer balances allocated to their accounts in the WESCO Deferred Compensation Plan into any of the available investment options. The WESCO Deferred Compensation Plan is an unfunded plan. As of June 30, 2021, the Company's obligation under the WESCO Deferred Compensation Plan was $19.3 million, which was included in other noncurrent liabilities in the Condensed Consolidated Balance Sheet. As of December 31, 2020, the Company's obligation under the WESCO Deferred Compensation Plan was $27.4 million, of which $10.1 million was included in other current liabilities and $17.3 million was in other noncurrent liabilities in the Condensed Consolidated Balance Sheet.

Anixter Inc. sponsored a non-qualified deferred compensation plan (the "Anixter Deferred Compensation Plan") that permitted select employees to make pre-tax deferrals of salary and bonus. Interest was accrued monthly on the deferred compensation balances based on the average ten-year Treasury note rate for the previous three months times a factor of 1.4, and the rate was further adjusted if certain financial goals were achieved. In the fourth quarter of 2020, the Company terminated the Anixter Deferred Compensation Plan. Accordingly, the deferred compensation liability of $45.1 million was classified in other current liabilities in the Condensed Consolidated Balance Sheet at December 31, 2020. In the second quarter of 2021, the Company settled the liability for the Anixter Deferred Compensation Plan by making lump sum payments of $42.8 million directly to participants.

The Company held assets in a Rabbi Trust arrangement to provide for the liability associated with the Anixter Deferred Compensation Plan. The assets were invested in marketable securities. As of December 31, 2020, the assets held in this arrangement were $39.6 million and were recorded in other current assets in the Condensed Consolidated Balance Sheets. In the second quarter of 2021, the Company liquidated this investment arrangement for approximately $39.7 million and used the proceeds to fund the settlement of the Anixter Deferred Compensation Plan described above.

Defined Benefit Plans

WESCO sponsors a contributory defined benefit plan (the "EECOL Plan") covering substantially all Canadian employees of EECOL Electric Corp. and a Supplemental Executive Retirement Plan for certain executives of EECOL Electric Corp. (the "EECOL SERP").

Anixter Inc. sponsors defined benefit pension plans in the U.S., which consist of the Anixter Inc. Pension Plan, the Executive Benefit Plan and the Supplemental Executive Retirement Plan (the "Anixter SERP") (together, the "Domestic Plans") and various defined benefit pension plans covering employees of foreign subsidiaries in Canada and Europe (together with the "EECOL Plan" and "EECOL SERP", the "Foreign Plans"). The Anixter Inc. Pension Plan was frozen to entrants first hired or rehired on or after July 1, 2015. The majority of the Anixter defined benefit pension plans are non-contributory, and with the exception of U.S. and Canada, cover substantially all full-time employees in their respective countries. Retirement benefits are provided based on compensation as defined in each of the pension plans.

In the fourth quarter of 2020, the Company terminated both the Anixter Inc. Executive Benefit Plan and the Anixter SERP. Accordingly, pension liabilities totaling $18.1 million associated with the Anixter Inc. Executive Benefit Plan and the Anixter SERP were classified as current in the Condensed Consolidated Balance Sheet at December 31, 2020. In the second quarter of 2021, the Company settled its liability for the Anixter Inc. Executive Benefit Plan by making lump sum payments of $10.4 million directly to participants. The Company expects to make lump sum payments directly to participants of the Anixter SERP during the second half of 2021.

The Domestic Plans are funded as required by the Employee Retirement Income Security Act of 1974 ("ERISA") and the Internal Revenue Service and the Foreign Plans are funded as required by applicable foreign laws. The EECOL SERP and the Anixter SERP are unfunded plans.

The Company made aggregate cash contributions to its Foreign Plans of $3.1 million and $0.8 million during the three months ended June 30, 2021 and 2020, respectively, and $5.7 million and $1.8 million during the six months ended June 30, 2021 and 2020, respectively.

(1)    The Company assumed the Domestic Plans and certain foreign plans, as described above, in connection with the acquisition of Anixter on June 22, 2020. The Company began recognizing the net periodic pension (benefit) cost associated with these plans as of the acquisition date.

(2)    For the three and six months ended June 30, 2021 and 2020, no amounts were reclassified from accumulated other comprehensive income into net income, respectively.

The service cost of $4.1 million and $1.7 million for the three months ended June 30, 2021 and 2020, respectively, and $8.1 million and $3.0 million for the six months ended June 30, 2021 and 2020, respectively, is reported as a component of selling, general and administrative expenses. The other components of net periodic pension (benefit) cost totaling net benefits of $4.2 million and $0.7 million for the three months ended June 30, 2021 and 2020, respectively, and net benefits of $8.2 million and $1.2 million for the six months ended June 30, 2021 and 2020, respectively, are presented as a component of other non-operating income ("other income, net").

Other Benefits

As permitted by the Merger Agreement, Anixter granted restricted stock units prior to June 22, 2020 in the ordinary course of business to its employees and directors. These awards, which did not accelerate solely as a result of the Merger, were converted into cash-only settled WESCO phantom stock units, which vest ratably over a 3-year period. As of June 30, 2021 and December 31, 2020, the estimated fair value of these awards was $18.2 million and $22.8 million, respectively. The Company recognized compensation expense associated with these awards of $0.6 million and $0.9 million for the three months ended June 30, 2021 and 2020, respectively, and $6.3 million and $0.9 million for the six months ended June 30, 2021 and 2020, respectively, which is reported as a component of selling, general and administrative expenses.

10. FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company’s financial instruments primarily consist of cash and cash equivalents, accounts receivable, accounts payable, bank overdrafts, outstanding indebtedness, foreign currency forward contracts, and benefit plan assets. Except for benefit plan assets, outstanding indebtedness and foreign currency forward contracts, the carrying value of the Company’s remaining financial instruments approximates fair value.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

(unaudited)

The assets of the Company's various defined benefit plans are primarily comprised of common/collective/pool funds (i.e., mutual funds). These funds are valued at the net asset value (NAV) of shares held in the underlying funds. Investments for which fair value is measured using the NAV per share practical expedient are not classified in the fair value hierarchy.

The Company uses a market approach to determine the fair value of its debt instruments, utilizing quoted prices in active markets, interest rates and other relevant information generated by market transactions involving similar instruments. Therefore, the inputs used to measure the fair value of the Company's debt instruments are classified as Level 2 within the fair value hierarchy.

The carrying value of WESCO's debt instruments with fixed interest rates was $3,230.4 million and $3,730.1 million as of June 30, 2021 and December 31, 2020, respectively. The estimated fair value of this debt was $3,520.2 million and $4,084.7 million as of June 30, 2021 and December 31, 2020, respectively. The reported carrying values of WESCO's other debt instruments, including those with variable interest rates, approximated their fair values as of June 30, 2021 and December 31, 2020.

The Company purchases foreign currency forward contracts to minimize the effect of fluctuating foreign currency-denominated accounts on its earnings. The foreign currency forward contracts are not designated as hedges for accounting purposes. The Company's strategy is to negotiate terms for its derivatives and other financial instruments to be highly effective, such that the change in the value of the derivative offsets the impact of the underlying hedge. Its counterparties to foreign currency forward contracts have investment-grade credit ratings. The Company regularly monitors the creditworthiness of its counterparties to ensure no issues exist that could affect the value of its derivatives.

The Company does not hedge 100% of its foreign currency-denominated accounts. In addition, the results of hedging can vary significantly based on various factors, such as the timing of executing foreign currency forward contracts versus the movement of currencies as well as the fluctuations in the account balances throughout each reporting period. The fair value of foreign currency forward contracts is based on the difference between the contract rate and the current exchange rate. The fair value of foreign currency forward contracts is measured using observable market information. These inputs would be considered Level 2 in the fair value hierarchy. At June 30, 2021, foreign currency forward contracts were revalued at then-current foreign exchange rates with the changes in valuation reflected directly in other non-operating expenses ("other income, net") in the Condensed Consolidated Statements of Income and Comprehensive Income (Loss) offsetting the transaction gain (loss) recorded on foreign currency-denominated accounts. At June 30, 2021 and December 31, 2020, the gross and net notional amounts of foreign currency forward contracts outstanding were approximately $215.2 million and $111.9 million, respectively. While all of the Company's foreign currency forward contracts are subject to master netting arrangements with its counterparties, assets and liabilities related to these contracts are presented on a gross basis within the Condensed Consolidated Balance Sheets. The gross fair value of assets and liabilities related to foreign currency forward contracts were immaterial.

11. COMMITMENTS AND CONTINGENCIES

From time to time, a number of lawsuits and claims have been or may be asserted against the Company relating to the conduct of its business, including litigation relating to commercial, product and employment matters. The outcome of any litigation cannot be predicted with certainty, and some lawsuits may be determined adversely to WESCO. However, management does not believe that the ultimate outcome of any such pending matters is likely to have a material adverse effect on WESCO's financial condition or liquidity, although the resolution in any fiscal period of one or more of these matters may have a material adverse effect on WESCO's results of operations for that period.

12. INCOME TAXES

The effective tax rate for the three and six months ended June 30, 2021 was 21.6% and 18.1%, respectively. The effective tax rate for the three and six months ended June 30, 2020 was 24.0% and 67.3%, respectively. WESCO’s effective tax rate typically differs from the federal statutory income tax rate due to the tax effect of intercompany financing, foreign tax rate differences, the U.S. taxes imposed on foreign income, nondeductible expenses and state income taxes. The effective tax rate for the three months ended June 30, 2021 is lower than the corresponding quarter of the prior year primarily due to a discrete income tax benefit of $3.4 million associated with the exercise and vesting of stock-based awards. For the six months ended June 30, 2021, the effective tax rate is lower than the corresponding year-to-date period of the preceding year primarily due to the discrete income tax benefits of $8.3 million resulting from a change in the valuation allowance recorded against foreign tax credit carryforwards, and $4.5 million associated with the exercise and vesting of stock-based awards. In addition, the effective tax rates for the prior year periods were higher due to costs incurred to complete the acquisition of Anixter. There have been no material adjustments to liabilities for uncertain tax positions since the last annual disclosure for the year ended December 31, 2020.

13. BUSINESS SEGMENTS

The Company has operating segments that are organized around three strategic business units consisting of EES, CSS and UBS. These operating segments are equivalent to the Company's reportable segments. The Company's CODM evaluates the performance of its operating segments based primarily on net sales, income from operations, and total assets.

Corporate expenses are incurred to obtain and coordinate financing, tax, information technology, legal and other related services. The Company also has various corporate assets which are reported in corporate. Segment assets may not include jointly used assets, but segment results include depreciation expense or other allocations related to those assets. Interest expense and other non-operating items are not allocated to the segments or reviewed on a segment basis. Corporate expenses are shown in the tables below to reconcile the reportable segments to the consolidated financial statements.

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

The following discussion should be read in conjunction with the information in the unaudited condensed consolidated financial statements and notes thereto included herein and WESCO International, Inc.’s audited Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in its 2020 Annual Report on Form 10-K. The matters discussed herein may contain forward-looking statements that are subject to certain risks and uncertainties that could cause actual results to differ materially from expectations. Certain of these risks are set forth in WESCO International, Inc.'s Annual Report on Form 10-K for the fiscal year ended December 31, 2020, as well as WESCO International, Inc.’s other reports filed with the Securities and Exchange Commission (the "SEC").

Company Overview

WESCO International, Inc. ("WESCO International") and its subsidiaries (collectively, “WESCO” or the "Company"), headquartered in Pittsburgh, Pennsylvania, is a leading provider of business-to-business distribution, logistics services and supply chain solutions.

On June 22, 2020, we completed our acquisition of Anixter International Inc. ("Anixter"), a Delaware corporation. Pursuant to the terms of the Agreement and Plan of Merger, dated January 10, 2020, by and among Anixter, WESCO and Warrior Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of WESCO (“Merger Sub”), Merger Sub was merged with and into Anixter (the “Merger”), with Anixter surviving the Merger and continuing as a wholly owned subsidiary of WESCO. On June 23, 2020, Anixter merged with and into Anixter Inc., with Anixter Inc. surviving to become a wholly owned subsidiary of WESCO.

We employ nearly 18,000 people, maintain relationships with approximately 30,000 suppliers, and serve more than 125,000 customers worldwide. With nearly 1,500,000 products, end-to-end supply chain services, and extensive digital capabilities, we provide innovative solutions to meet current customer needs across commercial and industrial businesses, contractors, government agencies, institutions, telecommunications providers, and utilities. Our innovative value-add solutions include supply chain management, logistics and transportation, procurement, warehousing and inventory management, as well as kitting and labeling, limited assembly of products and installation enhancement. We have approximately 800 branches, warehouses and sales offices with operations in more than 50 countries, providing a local presence for customers and a global network to serve multi-location businesses and multi-national corporations.

During the second quarter of 2021, we established a new corporate brand strategy to adopt a single, master brand architecture. This initiative reflects our corporate integration strategy and simplifies engagement for our customers and suppliers. As a result, we will begin migrating certain legacy WESCO sub-brands to the master brand architecture over the course of the next year.

Prior to the completion of the Merger, we had four operating segments that had been aggregated as one reportable segment. Effective on the date of acquisition, we added Anixter as a separate reportable segment for the quarterly period ended June 30, 2020. At the beginning of the third quarter of 2020, we identified new operating segments organized around three strategic business units consisting of Electrical & Electronic Solutions ("EES"), Communications & Security Solutions ("CSS") and Utility and Broadband Solutions ("UBS"). The applicable comparative financial information reported in our previously issued interim financial statements for the three and six months ended June 30, 2020 has been recast in this Quarterly Report on Form 10-Q to conform to the basis of the new segments.

The following is a description of each of our reportable segments and their business activities.

Electrical & Electronic Solutions

The EES segment supplies a broad range of products and supply chain solutions primarily to the Construction, Industrial and Original Equipment Manufacturer ("OEM") markets. Product categories include a broad range of electrical equipment and supplies, wire and cable, lubricants, pipe, valves, fittings, fasteners, cutting tools, power transmission, and safety products. In addition, OEM customers require a reliable supply of assemblies and components to incorporate into their own products as well as value-add services such as supplier consolidation, design and technical support, just-in-time supply and electronic commerce, and supply chain management. EES includes the “Electrical and Electronic Solutions” business acquired from Anixter and the majority of WESCO's legacy industrial and construction businesses.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES

Communications & Security Solutions

The CSS segment supplies products and customized supply chain solutions to customers in a diverse range of industries including technology, finance, telecommunications service providers, transportation, education, government, healthcare and retail. CSS sells these products directly to end users or through various channels including data communications contractors, security, network, professional audio/visual and systems integrators. CSS has a broad product portfolio that includes copper and fiber optic cable and connectivity, access control, video surveillance, intrusion and fire/life safety, cabinets, power, cable management, wireless, professional audio/video, voice and networking switches and other ancillary products. CSS includes the “Network and Security Solutions” business acquired from Anixter and WESCO's legacy data communications and safety businesses.

Utility & Broadband Solutions

The UBS segment supplies electrical transmission and distribution products, power plant maintenance, repair and operations supplies and smart-grid products, and arranges materials management and procurement outsourcing for the power generation, power transmission and electricity distribution industries. The UBS segment combines the “Utility Power Solutions” business acquired from Anixter, and WESCO's legacy utility, broadband and integrated supply businesses.

Overall Financial Performance

Our financial results for the first six months of 2021 reflect the merger with Anixter, broad-based sales growth due to strong demand and improved economic conditions, the favorable impacts of margin improvement initiatives and lower operating expenses due to cost reduction actions and integration synergies, partially offset by higher salaries, variable compensation expense and benefit costs.

Net sales for the first six months of 2021 increased $4.6 billion, or 113.0%, over the corresponding year-to-date period. In addition to the impact from the Merger, the increase reflects improved economic conditions and strong demand. Cost of goods sold as a percentage of net sales and gross margin was 79.4% and 20.6%, respectively, for the first six months of 2021, compared to 81.0% and 19.0%, respectively, for the first six months of 2020. The increase in gross margin of 160 basis points reflects the favorable impact of margin improvement initiatives, partially offset by write-downs to the carrying value of certain personal protective equipment products during the first and second quarters of 2021, which had a negative impact of 20 basis points for the six months ended June 30, 2021.

Operating profit was $352.1 million for the first six months of 2021, compared to $76.2 million for the first six months of 2020. Operating profit as a percentage of net sales was 4.1% for the current six-month period, compared to 1.9% for the first six months of the prior year. Operating profit for the first six months of 2021 includes merger-related costs of $84.0 million and a net gain of $8.9 million resulting from the sale of WESCO's legacy utility and data communications businesses in Canada during the first quarter of 2021, which were divested in connection with the Merger. Additionally, we recognized $5.0 million of amortization expense for the six months ended June 30, 2021 resulting from changes in the estimated useful lives of certain legacy WESCO trademarks that are migrating to our master brand architecture, as described in Note 2, "Accounting Policies" of our Notes to the unaudited Condensed Consolidated Financial Statements. Adjusted for these items, operating profit was $432.3 million, or 5.0% of net sales. For the first six months of 2020, operating profit adjusted for merger-related costs of $78.0 million was $154.1 million, or 3.8% of net sales.

Earnings per diluted share for the first six months of 2021 was $2.89, based on 51.9 million diluted shares, compared to a loss per diluted share of $0.03 for the first six months of 2020, based on 42.3 million diluted shares. Adjusted for merger-related costs and interest, the net gain on the Canadian divestitures, accelerated trademark amortization expense, and the related income tax effects, earnings per diluted share for the first six months of 2021 and 2020 was $4.06 and $2.25, respectively, an increase of 80.4%.

Beginning in 2020, and continuing through the second quarter of 2021, the COVID-19 pandemic had a significant impact on our business, and there continues to be significant uncertainties associated with the COVID-19 pandemic, including with respect to the economic conditions and possible resurgence of COVID, including new variants of the virus in various geographies, and the availability and effectiveness of treatments and vaccines. As the duration and severity of the COVID-19 pandemic remain uncertain and cannot be predicted, there is significant uncertainty as to the ultimate impact it will have on our business and our results of operations and financial condition. Events and factors relating to the COVID-19 pandemic include limitations on the ability of our suppliers to manufacture or procure the products we sell or to meet delivery requirements and commitments; disruptions to our global supply chains; limitations on the ability of our employees to perform their work due to travel or other restrictions; limitations on the ability of carriers to deliver our products to our customers; limitations on the ability of our customers to conduct their business and purchase our products and services, or pay us on a timely basis; and disruptions to our customers’ purchasing patterns. In response to the COVID-19 pandemic, we have taken actions focused on protecting the health and safety of our employees, which is our top priority.

26

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES

The products and services that we provide are integral to the daily operations of our customers and accordingly, we have taken actions to maintain the continuity of our operations in response to the pandemic. We have experienced, and may continue to experience, fluctuations in customer demand for certain of our products and services, including changes in project plans or timing due to circumstances affecting our customers, suppliers and other third parties. The full extent to which the COVID-19 pandemic will continue to impact our business and financial results going forward remains highly uncertain and will depend on many factors outside of our control, including the duration and scope of the crisis, the emergence and effects of variants, the availability of effective treatments and vaccines, imposition of protective public safety measures, and the overall impact of the COVID-19 pandemic on the global economy and capital markets.

Cash Flow

We generated $102.8 million of operating cash flow for the first six months of 2021. Cash provided by operating activities included net income of $178.4 million and adjustments to net income totaling $101.8 million, which were primarily comprised of depreciation and amortization of $87.9 million, stock-based compensation expense of $13.2 million, amortization of debt discount and debt issuance costs of $9.2 million, a net gain of $8.9 million resulting from the divestiture of WESCO's legacy utility and data communications businesses in Canada, as described in Note 4, "Acquisitions and Disposals" of our Notes to the unaudited Condensed Consolidated Financial Statements, and deferred income taxes of $3.0 million. Operating cash flow also included changes in assets and liabilities of $177.5 million, which were primarily comprised of an increase in trade accounts receivable of $372.3 million resulting from higher sales in the latter part of the quarter and an increase in inventories of $268.3 million to support increased customer demand, partially offset by an increase in accounts payable of $474.9 million due to higher purchases of inventory.

Investing activities included $54.3 million of net proceeds from the Canadian divestitures and $20.2 million of capital expenditures.

Financing activities were primarily comprised of the redemption of our $500.0 million aggregate principal amount of 5.375% Senior Notes due 2021 (the "2021 Notes"), borrowings and repayments of $914.8 million and $869.8 million, respectively, related to our revolving credit facility (the "Revolving Credit Facility"), and borrowings and repayments of $643.0 million and $413.0 million, respectively, related to our accounts receivable securitization facility (the "Receivables Facility"). Financing activities for the first six months of 2021 also included $28.7 million of dividends paid to holders of our Series A Preferred Stock, net repayments related to our various international lines of credit of approximately $10.8 million, and $12.4 million of payments for taxes related to the exercise and vesting of stock-based awards.

Financing Availability

On June 1, 2021, we amended our Receivables Facility to increase its borrowing capacity from $1,200 million to $1,300 million, extend its maturity date from June 22, 2023 to June 21, 2024, decrease its LIBOR floor from 0.50% to 0.00% and decrease its interest rate spread from 1.20% to 1.15%. Borrowings under the amended accounts receivable securitization facility will be used to redeem our $350 million aggregate principal amount of 5.375% Senior Notes due 2024 (the "2024 Notes"), as described in Note 14, "Subsequent Events" of our Notes to the unaudited Condensed Consolidated Financial Statements.

As of June 30, 2021, we had $873.1 million in total available borrowing capacity under our Revolving Credit Facility, which was comprised of $581.7 million of availability under the U.S. sub-facility and $291.4 million of availability under the Canadian sub-facility. Available borrowing capacity under our Receivables Facility was $120.0 million. The Revolving Credit Facility and the Receivables Facility mature in June 2025 and June 2024, respectively.

Critical Accounting Policies and Estimates

We adopted Accounting Standards Update ("ASU") 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, in the first quarter of 2021. The adoption of this ASU did not have a material impact on our consolidated financial statements and notes thereto.

During the second quarter of 2021, we made changes to the estimated useful lives of certain legacy WESCO trademarks that are migrating to our master brand architecture, as disclosed in Note 2, "Accounting Policies" of our Notes to the unaudited Condensed Consolidated Financial Statements.

See Note 2, "Accounting Policies" of our Notes to the unaudited Condensed Consolidated Financial Statements for more information regarding our significant accounting policies.

Net Sales

The following table sets forth net sales by segment for the periods presented:

	Three Months Ended
(In thousands)	June 30, 2021		June 30, 2020		Growth
EES	$	1,923,011	$	1,043,294	84.3	%
CSS	1,461,120		341,470		327.9	%
UBS	1,211,659		701,942		72.6	%
Total net sales	$	4,595,790	$	2,086,706	120.2	%

Net sales were $4.6 billion for the second quarter of 2021, compared to $2.1 billion for the second quarter of 2020, an increase of 120.2%. The increase primarily reflects the merger with Anixter that was completed on June 22, 2020, along with growth across all segments, as described below.

EES reported net sales $1.9 billion for the second quarter of 2021, compared to $1.0 billion for the second quarter of 2020, an increase of 84.3%. In addition to the impact of the Merger, the increase reflects double-digit growth in our construction, original equipment manufacturer and industrial businesses due to continued strong demand and accelerating economic recovery in certain regions.

CSS reported net sales of $1.5 billion for the second quarter of 2021, compared to $341.5 million for the second quarter of 2020, an increase of 327.9%. In addition to the impact of the Merger, the increase reflects strong sales growth in both our security solutions and network infrastructure businesses driven by the rebound in the global economy, a rise in project activity, and new wins from our expanding business.

UBS reported net sales of $1.2 billion for the second quarter of 2021, compared to $701.9 million for the second quarter of 2020, an increase of 72.6%. Along with the impact of the Merger, the increase reflects broad-based growth in our utility business with strength in both the investor-owned utility and public power markets. UBS sales growth also reflects continued strong demand in our broadband business, as well as growth in our integrated supply business due to improving economic conditions.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES

Cost of Goods Sold

Cost of goods sold for the second quarter of 2021 was $3.6 billion compared to $1.7 billion for the second quarter of 2020, an increase of $1.9 billion, reflecting the merger with Anixter. Cost of goods sold as a percentage of net sales was 79.0% for the second quarter of 2021, compared to 81.1% for the second quarter of 2020. The decrease of 210 basis points primarily reflects the favorable impact of margin improvement initiatives, partially offset by a write-down of $8.0 million to the carrying value of certain personal protective equipment products that were considered to either be in excess of supply relative to demand or for which current net realizable value has declined below cost. This write-down of inventory impacted cost of goods sold as a percentage of net sales for the second quarter of 2021 by 20 basis points.

Selling, General and Administrative Expenses

SG&A expenses for the second quarter of 2021 totaled $699.6 million versus $359.8 million for the second quarter of 2020. As a percentage of net sales, SG&A expenses were 15.2% and 17.2%, respectively. The increase in SG&A expenses of $339.8 million, or 94.5%, primarily reflects the impact of the merger with Anixter. In addition, SG&A expenses in the current quarter reflect higher volume-related costs and SG&A payroll expenses, as described below. The realization of integration synergies and structural cost takeout actions favorably impacted SG&A expenses for the second quarter of 2021. SG&A expenses for the second quarter of 2021 include merger-related costs of $37.7 million. Adjusted for these costs, SG&A expenses were $661.9 million, or 14.4% of net sales, for the second quarter of 2021. SG&A expenses for the second quarter of 2020 include $73.3 million of merger-related costs. Adjusted for these costs, SG&A expenses were $286.4 million, or 13.7% of net sales, for the second quarter of 2020.

SG&A payroll expenses for the second quarter of 2021 of $458.4 million increased by $231.6 million compared to the same period in 2020 primarily due to the merger with Anixter. Excluding the impact of the Merger, SG&A payroll expenses were up $43.9 million in the current quarter due to higher variable compensation expense and benefit costs, as well as the impact of reinstating salaries and retirement savings plan employer matching contributions for legacy WESCO employees that had been suspended in the prior year in response to the COVID-19 pandemic.

Depreciation and Amortization

Depreciation and amortization increased $27.9 million to $46.7 million for the second quarter of 2021, compared to $18.8 million for the second quarter of 2020. The second quarter of 2021 includes $15.8 million attributable to the amortization of identifiable intangible assets acquired in the merger with Anixter, as well as $5.0 million resulting from changes in the estimated useful lives of certain legacy WESCO trademarks that are migrating to our master brand architecture, as described in Note 2, "Accounting Policies" of our Notes to the unaudited Condensed Consolidated Financial Statements. As of June 30, 2021, there is $42.8 million of estimated amortization expense remaining for trademarks migrating to our master brand architecture, of which approximately $15.4 million and $12.1 million are expected to be recognized in the third and fourth quarters of 2021, respectively.

Income from Operations

The following tables set forth income from operations by segment for the periods presented:

	Three Months Ended June 30, 2021
(In thousands)	EES		CSS		UBS		Corporate		Total
Income from operations	$	153,740	$	111,257	$	94,693	$	(140,818)	$	218,872
	Three Months Ended June 30, 2020
(In thousands)	EES		CSS		UBS		Corporate		Total
Income from operations	$	45,809	$	27,922	$	51,774	$	(110,235)	$	15,270

Operating profit was $218.9 million for the second quarter of 2021 compared to $15.3 million for the second quarter of 2020, an increase of $203.6 million. The increase primarily reflects the merger with Anixter. For the second quarter of 2021, operating profit also reflects the favorable impact of margin improvement initiatives, the realization of integration synergies and structural cost takeout actions. Operating profit for the second quarter of 2021 was negatively impacted by higher salaries, variable compensation expense and benefit costs compared to the prior year, including the impact of reinstating the salaries and certain benefits of legacy WESCO employees that had been suspended in the prior year in response to the COVID-19 pandemic.

29

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES

EES reported operating profit of $153.7 million for the second quarter of 2021, compared to $45.8 million for the second quarter of 2020, an increase of $107.9 million. The increase primarily reflects the factors impacting the overall business, as described above. Additionally, operating profit for the second quarter of 2021 was negatively impacted by the inventory write-down described above and accelerated amortization expense of $2.1 million associated with migrating to our master brand architecture.

CSS reported operating profit of $111.3 million for the second quarter of 2021, compared to $27.9 million for the second quarter of 2020, an increase of $83.4 million. The increase primarily reflects the factors impacting the overall business, as described above. Additionally, operating profit for the second quarter of 2021 was negatively impacted by $5.4 million from the inventory write-down described above, as well as accelerated amortization expense of $2.7 million associated with migrating to our master brand architecture.

UBS reported operating profit of $94.7 million for the second quarter of 2021, compared to $51.8 million for the second quarter of 2020, an increase of $42.9 million. The increase primarily reflects the factors impacting the overall business, as described above.

Interest Expense, net

Net interest expense totaled $67.6 million for the second quarter of 2021, compared to $61.3 million for the second quarter of 2020. The increase in interest expense was driven by financing activity related to the Anixter merger. Net interest expense for the second quarter of 2020 includes $44.7 million of merger-related financing and interest costs, of which $33.5 million was non-recurring.

Other Income, net

Other non-operating income ("other income, net") totaled $0.8 million for the second quarter of 2021, compared to $0.7 million for the second quarter of 2020.

Income Taxes

The provision for income taxes was an expense of $32.8 million for the second quarter of 2021, compared to a benefit of $10.9 million in last year's comparable period, and the effective tax rate was 21.6% and 24.0%, respectively. The lower effective tax rate in the current quarter as compared to the corresponding quarter of the prior year was primarily due to a discrete income tax benefit of $3.4 million associated with the exercise and vesting of stock-based awards. In addition, the effective tax rate for the corresponding quarter of the prior year was higher due to costs incurred to complete the merger with Anixter. Excluding the impact of the Merger, the effective tax rate for the prior quarter would have been approximately 22%.

Net Income (Loss) and Earnings (Loss) per Share

Net income for the second quarter of 2021 was $119.3 million, compared to a net loss of $34.5 million for the second quarter of 2020.

Net income attributable to noncontrolling interests was less than $0.1 million for the second quarter of 2021 and 2020.

Preferred stock dividends expense, which relates to the fixed-rate reset cumulative perpetual preferred stock, Series A, that was issued in connection with the Merger, was $14.4 million for the second quarter of 2021 compared to $1.3 million for the second quarter of 2020.

Net income and earnings per diluted share attributable to common stockholders were $104.8 million and $2.02 per diluted share, respectively, for the second quarter of 2021, compared with a net loss and loss per diluted share attributable to common stockholders of $35.8 million and $0.84 per diluted share, respectively, for the second quarter of 2020. Adjusted for merger-related costs, accelerated amortization expense associated with migrating to our master brand architecture, and the related income tax effects, net income and earnings per diluted share attributable to common stockholders for the three months ended June 30, 2021 were $137.2 million and $2.64, respectively. Adjusted for merger-related costs and interest, the related income tax effects, and the weighted-average impact of 8.15 million shares of common stock issued as equity consideration to fund a portion of the merger with Anixter, net income and earnings per diluted share attributable to common stockholders were $55.9 million and $1.33, respectively, for the three months ended June 30, 2020.

Net Sales

The following table sets forth net sales by segment for the periods presented:

	Six Months Ended
(In thousands)	June 30, 2021		June 30, 2020		Growth
EES	$	3,643,824	$	2,157,766	68.9	%
CSS	2,711,735		565,185		379.8	%
UBS	2,281,708		1,332,402		71.2	%
Total net sales	$	8,637,267	$	4,055,353	113.0	%

Net sales were $8.6 billion for the first six months of 2021, compared to $4.1 billion for the first six months of 2020, an increase of 113.0%. The increase primarily reflects the merger with Anixter, along with growth across all segments, as described below.

EES reported net sales $3.6 billion for the first six months of 2021, compared to $2.2 billion for the first six months of 2020, an increase of 68.9%. In addition to the impact of the Merger, the increase reflects growth in our construction and original equipment manufacturer businesses due to continued strong demand and improving economic conditions.

CSS reported net sales of $2.7 billion for the first six months of 2021, compared to $565.2 million for the first six months of 2020, an increase of 379.8%. The increase reflects the impact from the Merger and broad-based growth in our security solutions and network infrastructure businesses.

UBS reported net sales of $2.3 billion for the first six months of 2021, compared to $1.3 billion for the first six months of 2020, an increase of 71.2%. Along with the impact of the Merger, the increase reflects broad-based growth in our utility business, continued strong demand in our broadband business, and growth from integrated supply programs.

Cost of Goods Sold

Cost of goods sold for the first six months of 2021 was $6.9 billion compared to $3.3 billion for the first six months of 2020, an increase of $3.6 billion, reflecting the merger with Anixter. Cost of goods sold as a percentage of net sales was 79.4% for the first six months of 2021, compared to 81.0% for the first six months of 2020. The decrease of 160 basis points primarily reflects the favorable impact of margin improvement initiatives, partially offset by a write-down of $16.9 million to the carrying value of certain personal protective equipment products that were considered to either be in excess of supply relative to demand or for which current net realizable value has declined below cost. This write-down of inventory impacted cost of goods sold as a percentage of net sales for the first six months of 2021 by 20 basis points.

Selling, General and Administrative Expenses

SG&A expenses for the first six months of 2021 totaled $1.3 billion versus $659.1 million for the first six months of 2020. As a percentage of net sales, SG&A expenses were 15.5% and 16.3%, respectively. The increase in SG&A expenses of $677.0 million, or 102.7%, primarily reflects the impact of the merger with Anixter. In addition, SG&A expenses in the current year reflect higher volume-related costs and SG&A payroll expenses, as described below. SG&A expenses for the first six months of 2021 were favorably impacted by the realization of integration synergies and structural cost takeout actions, as well as lower travel, entertainment and similar expenses due to restrictions imposed on non-essential business travel in response to the COVID-19 pandemic. SG&A expenses for the first six months of 2021 include merger-related costs of $84.0 million, as well as a net gain of $8.9 million resulting from the sale of WESCO's legacy utility and data communications businesses in Canada, which were divested during the first quarter of 2021 in connection with the Merger. Adjusted for these amounts, SG&A expenses were 14.6% of net sales for the first six months of 2021. SG&A expenses for the first six months of 2020 include $78.0 million of merger-related costs. Adjusted for these costs, SG&A expenses were $581.2 million, or 14.3% of net sales, for the first six months of 2020.

SG&A payroll expenses for the first six months of 2021 of $882.1 million increased by $451.7 million compared to the same period in 2020 primarily due to the merger with Anixter. Excluding the impact of the Merger, SG&A payroll expenses were up $48.8 million in the current year due to higher variable compensation expense and benefit costs, as well as the impact of reinstating salaries and retirement savings plan employer matching contributions for legacy WESCO employees that had been suspended in the prior year in response to the COVID-19 pandemic.

Depreciation and Amortization

Depreciation and amortization increased $53.1 million to $87.9 million for the first six months of 2021, compared to $34.8 million for the first six months of 2020. The six months ended June 30, 2021 includes $31.4 million attributable to the amortization of identifiable intangible assets acquired in the merger with Anixter, as well as $5.0 million resulting from changes in the estimated useful lives of certain legacy WESCO trademarks that are migrating to our master brand architecture, as described in Note 2, "Accounting Policies" of our Notes to the unaudited Condensed Consolidated Financial Statements. As of June 30, 2021, there is $42.8 million of estimated amortization expense remaining for trademarks migrating to our master brand architecture, of which approximately $27.5 million is expected to be recognized over the remainder of 2021, $10.0 million in 2022 and $5.3 million thereafter.

Income from Operations

The following tables set forth income from operations by segment for the periods presented:

	Six Months Ended June 30, 2021

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES

Operating profit was $352.1 million for the first six months of 2021 compared to $76.2 million for the first six months of 2020, an increase of 362.2%. The increase primarily reflects the merger with Anixter. For the first six months of 2021, operating profit also reflects the favorable impact of margin improvement initiatives, the realization of integration synergies and structural cost takeout actions. Additionally, income from operations reflects the benefit of lower travel, entertainment and similar expenses due to restrictions imposed on non-essential business travel in response to the COVID-19 pandemic. Operating profit for the first six months of 2021 was negatively impacted by higher salaries, variable compensation expense and benefit costs, as well as the impact of reinstating salaries and certain benefits of legacy WESCO employees that had been suspended in the prior year in response to the COVID-19 pandemic.

EES reported operating profit of $253.9 million for the first six months of 2021, compared to $89.1 million for the first six months of 2020, an increase of $164.7 million. The increase primarily reflects the factors impacting the overall business, as described above. Additionally, operating profit for the first six months of 2021 was negatively impacted by the inventory write-down described above and accelerated amortization expense of $2.1 million associated with migrating to our master brand architecture.

CSS reported operating profit of $185.2 million for the first six months of 2021, compared to $37.9 million for the first six months of 2020, an increase of $147.4 million. The increase primarily reflects the factors impacting the overall business, as described above. Additionally, operating profit for the first six months of 2021 was negatively impacted by $12.9 million from the inventory write-down described above, as well as accelerated amortization expense of $2.7 million associated with migrating to our master brand architecture.

UBS reported operating profit of $181.7 million for the first six months of 2021, compared to $93.6 million for the first six months of 2020, an increase of $88.2 million. The increase primarily reflects the factors impacting the overall business, as described above, combined with the benefit from the gain on the Canadian divestitures.

Interest Expense, net

Net interest expense totaled $138.0 million for the first six months of 2021, compared to $77.9 million for the first six months of 2020. The increase in interest expense was driven by financing activity related to the Anixter merger. Net interest expense for the first six months of 2020 includes $45.3 million of merger-related financing and interest costs, of which $33.5 million was non-recurring.

Other Income, net

Other non-operating income ("other income, net") totaled $3.6 million for the first six months of 2021, compared to $0.8 million for the first six months of 2020.

Income Taxes

The provision for income taxes was an expense of $39.3 million for the first six months of 2021, compared to a benefit of $0.6 million in last year's comparable period, and the effective tax rate was 18.1% and 67.3%, respectively. The lower effective tax rate in the current period was primarily due to the discrete income tax benefits of $8.3 million and $4.5 million associated with a change in the valuation allowance recorded against foreign tax credit carryforwards and the exercise and vesting of stock-based awards, respectively, which together reduced the effective tax rate by approximately 5.9 percentage points. In addition, the effective tax rate in the corresponding preceding year-to-date period was higher due to costs incurred to complete the merger with Anixter. Excluding the impact of the Merger, the effective tax rate for the first six months of 2020 would have been approximately 22%.

Net Income (Loss) and Earnings (Loss) per Share

Net income for the first six months of 2021 was $178.4 million, compared to a net loss of $0.3 million for the first six months of 2020.

Net income attributable to noncontrolling interests was less than $0.1 million for the first six months of 2021, compared to a net loss of $0.2 million for the first six months of 2020.

Preferred stock dividends expense, which relates to the fixed-rate reset cumulative perpetual preferred stock, Series A, that was issued in connection with the Merger, was $28.7 million for the first six months of 2021 compared to $1.3 million for the first six months of 2020.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES

Net income and earnings per diluted share attributable to common stockholders were $149.7 million and $2.89 per diluted share, respectively, for the first six months of 2021, compared with a net loss and loss per diluted share attributable to common stockholders of $1.4 million and $0.03 per diluted share, respectively, for the first six months of 2020. Adjusted for merger-related costs, the net gain on the sale of WESCO's legacy utility and data communications businesses in Canada, accelerated amortization expense associated with migrating to our master brand architecture, and the related income tax effects, net income and earnings per diluted share attributable to common stockholders for the six months ended June 30, 2021 were $210.5 million and $4.06, respectively. Adjusted for merger-related costs and interest, the related income tax effects, and the weighted-average impact of 8.15 million shares of common stock issued as equity consideration to fund a portion of the merger with Anixter, net income and earnings per diluted share attributable to common stockholders were $94.3 million and $2.25, respectively, for the six months ended June 30, 2020.

Liquidity and Capital Resources

Our liquidity needs generally arise from fluctuations in our working capital requirements, capital expenditures, acquisitions and debt service obligations. As of June 30, 2021, we had $873.1 million in available borrowing capacity under our Revolving Credit Facility and $120.0 million in available borrowing capacity under our Receivables Facility, which combined with available cash of $118.1 million, provided liquidity of $1.1 billion. Cash included in our determination of liquidity represents cash in certain deposit and interest bearing investment accounts. We believe cash provided by operations and financing activities will be adequate to cover our operational and business needs for at least the next twelve months. In addition, we regularly review our mix of fixed versus variable rate debt, and we may, from time to time, issue or retire borrowings and/or refinance existing debt in an effort to mitigate the impact of interest rate and foreign exchange rate fluctuations, and to maintain a cost-effective capital structure consistent with our anticipated capital requirements. At June 30, 2021, approximately 68% of our debt portfolio was comprised of fixed rate debt.

As described in Note 8, "Debt" of our Notes to the unaudited Condensed Consolidated Financial Statements, on January 14, 2021, we redeemed the $500 million aggregate principal amount of our 2021 Notes at a redemption price equal to 100% of the principal amount plus accrued interest to, but not including, January 14, 2021. The redemption of the 2021 Notes was funded with available cash, as well as borrowings under our accounts receivable securitization and revolving credit facilities.

As also described in Note 8, "Debt" of our Notes to the unaudited Condensed Consolidated Financial Statements, on June 2, 2021, we exercised our right to redeem the $350 million aggregate principal amount of our 2024 Notes at a redemption price equal to 101.344% of the principal amount plus accrued interest to, but not including, July 2, 2021, the date fixed for the redemption. See Note 14, "Subsequent Events" of our Notes to the unaudited Condensed Consolidated Financial Statements for more information.

As a result of the redemption of the 2024 Notes and amendment to the Receivables Facility, as described above, total interest expense is expected to be reduced by approximately $2 million in 2021 and $18 million per year thereafter based on current interest rates.

Since the merger with Anixter, we have used cash and the net proceeds from the divestiture of WESCO's legacy utility and data communications businesses in Canada to reduce our debt, net of cash, by approximately $464 million. Over the next several quarters, it is expected that excess liquidity will be directed primarily at debt reduction and merger-related integration activities, and we expect to maintain sufficient liquidity through our credit facilities and cash balances. We expect to spend between $100 million to $120 million in 2021 on capital expenditures and cloud-based initiatives, much of which will be invested to align the systems of our legacy businesses and enhance our digital tools.

We monitor the depository institutions that hold our cash and cash equivalents on a regular basis, and we believe that we have placed our deposits with creditworthy financial institutions. We also communicate on a regular basis with our lenders regarding our financial and working capital performance, liquidity position and financial leverage. Our financial leverage ratio, on a pro forma basis, was 4.5 as of June 30, 2021 and 5.3 as of December 31, 2020. In addition, we are in compliance with all covenants and restrictions contained in our debt agreements as of June 30, 2021.

Financial leverage ratio	4.5		5.3

(1)Pro forma adjusted EBITDA includes the financial results of WESCO's legacy utility and data communications businesses in Canada, which were divested in the first quarter of 2021 under a Consent Agreement with the Competition Bureau of Canada.

(2)Debt is presented in the condensed consolidated balance sheets net of debt discount and debt issuance costs, and includes adjustments to record the long-term debt assumed in the merger with Anixter at its acquisition date fair value.

Note: Financial leverage measures the use of debt. Financial leverage ratio is calculated by dividing total debt, excluding debt discount, debt issuance costs and fair value adjustments, net of cash, by adjusted EBITDA. EBITDA is defined as the trailing twelve months earnings before interest, taxes, depreciation and amortization. Adjusted EBITDA is defined as the trailing twelve months EBITDA before foreign exchange and other non-operating expenses (income), non-cash stock-based compensation, costs and fair value adjustments associated with the merger with Anixter, an out-of-period adjustment related to inventory absorption accounting, and net gain on the sale of a U.S. operating branch and WESCO's legacy utility and data communications businesses in Canada. Pro forma financial leverage ratio is calculated by dividing total debt, excluding debt discount and debt issuance costs, net of cash, by pro forma adjusted EBITDA. Pro forma EBITDA and pro forma adjusted EBITDA gives effect to the combination of WESCO and Anixter as if it had occurred at the beginning of the respective trailing twelve month period.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES

Most of the undistributed earnings of our foreign subsidiaries have been taxed in the U.S. under either the one-time transition tax or the global intangible low-taxed income ("GILTI") tax regime imposed by the Tax Cuts and Jobs Act of 2017 ("TCJA"). Except for a portion of foreign earnings previously taxed in the U.S. that can effectively be distributed without further material U.S. or foreign taxation, we continue to assert that the undistributed earnings of our foreign subsidiaries are indefinitely reinvested. To the extent the earnings of our foreign subsidiaries are distributed in the form of dividends, such earnings may be subject to additional taxes. We believe that we are able to maintain a sufficient level of liquidity for our domestic operations and commitments without incurring any material tax cost to repatriate cash held by our foreign subsidiaries.

Cash Flow

Operating Activities. Net cash generated from operations for the first six months of 2021 totaled $102.8 million, compared to $132.7 million for the first six months of 2020.

Additionally, we paid $79.5 million of debt issuance costs associated with financing the merger with Anixter.

Contractual Cash Obligations and Other Commercial Commitments

There were no material changes in our contractual obligations and other commercial commitments that would require an update to the disclosure provided in our 2020 Annual Report on Form 10-K.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES

Inflation

The rate of inflation, as measured by changes in the producer price index, affects different commodities, the cost of products purchased and ultimately the pricing of our different products and product classes to our customers. For the six months ended June 30, 2021, pricing related to inflation did not have a material impact on our operating profit.

Seasonality

Our operating results are not significantly affected by seasonal factors. Sales during the first and fourth quarters are usually affected by a reduced level of activity due to the impact of weather on projects. Sales typically increase beginning in March, with slight fluctuations per month through October. During periods of economic expansion or contraction, our sales by quarter have varied significantly from this pattern.

Guarantor Financial Statements

WESCO Distribution (the “Issuer”) has outstanding $350 million in aggregate principal amount of 5.375% Senior Notes due 2024 (the “2024 Notes”).

The 2024 Notes are unsecured senior obligations of WESCO Distribution and are fully and unconditionally guaranteed on a senior unsecured basis by WESCO International and Anixter Inc. (the “Guarantors”), ranking pari passu in right of payment with all other existing and future senior obligations of the Issuer, including obligations under other unsubordinated indebtedness. The 2024 Notes are effectively subordinated to all existing and future obligations of the Issuer that are secured by liens on any property or assets of the Issuer, including the Issuer’s Revolving Credit Facility and the then outstanding term loan facility (the “Senior Secured Credit Facilities”), to the extent of the value of the collateral securing such obligations, and are structurally subordinated to all liabilities (including trade payables) of any of the Guarantors’s or the Issuer’s subsidiaries (the “non-Guarantor Subsidiaries”) and senior in right of payment to all existing and future obligations of the Issuer that are, by their terms, subordinated in right of payment to the 2024 Notes.

The 2024 Notes are guaranteed by the Guarantors and not by the non-Guarantor Subsidiaries. In the event of a bankruptcy, liquidation or reorganization of any of the non-Guarantor Subsidiaries, such non-Guarantor Subsidiaries will pay the holders of their debt and their trade creditors before they will be able to distribute or contribute, as the case may be, any of their assets to the Issuer or the Guarantors. Therefore, the 2024 Notes and the guarantee of the Guarantors (the “Guarantee”) are effectively subordinated to the liabilities of the non-Guarantor Subsidiaries.

The Guarantee constitutes a senior obligation of the Guarantors, ranking pari passu in right of payment with all other senior obligations of the Guarantors, including obligations under other unsubordinated indebtedness. The Guarantee is effectively subordinated to all existing and future obligations incurred by the Guarantors that are secured by liens on any property or assets of the Guarantors, including the Senior Secured Credit Facilities, to the extent of the value of the collateral securing such obligations, structurally subordinated to all liabilities (including trade payables) of the non-Guarantor Subsidiaries and senior in right of payment to all existing and future obligations of the Guarantors that are, by their terms, subordinated in right of payment to the Guarantee.

The Guarantors guarantee to each holder of the 2024 Notes and to the respective trustees (i) the due and punctual payment of the principal of, premium, if any, and interest on each Note, when and as the same shall become due and payable, whether at maturity, by acceleration or otherwise, the due and punctual payment of interest on the overdue principal of and interest on the 2024 Notes, to the extent lawful, and the due and punctual payment of all other obligations and due and punctual performance of all obligations of the Issuer to the holders or the respective trustee all in accordance with the terms of the 2024 Notes and the indentures governing the 2024 Notes and (ii) in the case of any extension of time of payment or renewal of any 2024 Notes or any of such other obligations, that the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, at stated maturity, by acceleration or otherwise.

If the Issuer becomes a debtor in a case under the U.S. Bankruptcy Code or encounters other financial difficulty, under federal or state fraudulent transfer law, a court may void, subordinate or otherwise decline to enforce the 2024 Notes. A court might do so if it is found that when the Issuer issued the 2024 Notes, or in some states when payments became due under the 2024 Notes, the Issuer received less than reasonably equivalent value or fair consideration and either: (i) were insolvent or rendered insolvent by reason of such incurrence; (ii) were left with inadequate capital to conduct its business; or (iii) believed or reasonably should have believed that the Issuer would incur debts beyond its ability to pay.

43

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES

A court might also void an issuance of the 2024 Notes without regard to the above factors, if the court found that the Issuer issued the 2024 Notes with actual intent to hinder, delay or defraud its creditors. A court would likely find that the Issuer did not receive reasonably equivalent value or fair consideration for the 2024 Notes, if the Issuer did not substantially benefit directly or indirectly from the issuance of the 2024 Notes. If a court were to void the issuance of the 2024 Notes, holders would no longer have any claim against the Issuer. Sufficient funds to repay the 2024 Notes may not be available from other sources. In addition, the court might direct holders to repay any amounts that they already received from the Issuer.

The following tables present summarized financial information for WESCO International, WESCO Distribution and Anixter Inc. on a combined basis after elimination of (i) intercompany transactions and balances among such entities and (ii) equity in earnings from and investments in any subsidiary that is a non-guarantor. The summarized financial information has been prepared in accordance with Rule 13-01 of Regulation S-X.

Forward-Looking Statements

All statements made herein that are not historical facts should be considered as forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements involve known and unknown risks, uncertainties and other factors that may cause actual results to differ materially. These statements include, but are not limited to, statements regarding the expected benefits and costs of the transaction between WESCO and Anixter International Inc., including anticipated future financial and operating results, synergies, accretion and growth rates, and the combined company's plans, objectives, expectations and intentions, statements that address the combined company's expected future business and financial performance, and other statements identified by words such as "anticipate," "plan," "believe," "estimate," "intend," "expect," "project," "will" and similar words, phrases or expressions. These forward-looking statements are based on current expectations and beliefs of WESCO's management, as well as assumptions made by, and information currently available to, WESCO's management, current market trends and market conditions and involve risks and uncertainties, many of which are outside of WESCO's and WESCO's management's control, and which may cause actual results to differ materially from those contained in forward-looking statements. Accordingly, you should not place undue reliance on such statements.

Those risks, uncertainties and assumptions include the risk of any unexpected costs or expenses resulting from the transaction, the risk of any litigation or post-closing regulatory action relating to the transaction, the risk that the transaction could have an adverse effect on the ability of the combined company to retain customers and retain and hire key personnel and maintain relationships with its suppliers, customers and other business relationships and on its operating results and business generally, or the risk that problems may arise in successfully integrating the businesses of the companies, which may result in the combined company not operating as effectively and efficiently as expected, the risk that the combined company may be unable to achieve synergies or other anticipated benefits of the proposed transaction or it may take longer than expected to achieve those synergies or benefits, the risk that the leverage of the company may be higher than anticipated, the impact of natural disasters, health epidemics and other outbreaks, especially the outbreak of COVID-19 since December 2019, which may have a material adverse effect on the combined company's business, results of operations and financial conditions, and other important factors that could cause actual results to differ materially from those projected. All such factors are difficult to predict and are beyond each company's control. Additional factors that could cause results to differ materially from those described above can be found in WESCO's Annual Report on Form 10-K for the fiscal year ended December 31, 2020 and WESCO's other reports filed with the SEC.

Item 3.    Quantitative and Qualitative Disclosures about Market Risks.

For a discussion of changes to the market risks that were previously disclosed in our 2020 Annual Report on Form 10-K, refer to Part I, Item 2, "Management's Discussion and Analysis of Financial Condition and Results of Operations” and to Part II, Item 1A, "Risk Factors”.

Item 4.    Controls and Procedures.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)). Based on this evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures and internal control over financial reporting were effective as of the end of the period covered by this report.

There were no changes in the Company’s internal control over financial reporting that occurred during the quarterly period ended June 30, 2021, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time, a number of lawsuits and claims have been or may be asserted against us relating to the conduct of our business, including litigation relating to commercial, product and employment matters. The outcome of any litigation cannot be predicted with certainty, and some lawsuits may be determined adversely to us. However, management does not believe that the ultimate outcome of any such pending matters is likely to have a material adverse effect on our financial condition or liquidity, although the resolution in any fiscal period of one or more of these matters may have a material adverse effect on our results of operations for that period.

Item 1A. Risk Factors.

There have been no material changes to the risk factors previously disclosed in Item 1A. to Part 1 of WESCO’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

central bank or other Governmental Authority (whether or not having the force of law), there shall be any increase in the cost to any Affected Person of agreeing to purchase or purchasing, or maintaining the ownership of, the Purchased Interest or any portion thereof in respect of which Discount is computed by reference to the Euro-Rate or the LMIRapplicable Benchmark, then, upon demand by such Affected Person, the Seller shall promptly pay to such Affected Person, from time to time as specified by such Affected Person, additional amounts sufficient to compensate such Affected Person for such increased costs. A certificate as to such amounts submitted to the Seller and the Administrator by such Affected Person shall be conclusive and binding for all purposes, absent manifest error.

(c)    If such increased costs affect the related Affected Person’s portfolio of financing transactions, such Affected Person shall use reasonable averaging and attribution methods to allocate such increased costs to the transactions contemplated by this Agreement.

(d)    Notwithstanding anything to the contrary, for purposes of this Section 1.7, (i) the Dodd-Frank Wall Street Reform and Consumer Protection Act, and all requests, rules, guidelines and directives promulgated thereunder and (ii) all requests, rules, guidelines or directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or any Governmental Authority, any central bank of any jurisdiction, comparable agency or other Person, in each case pursuant to, or implementing, the accord know as Basel II or Basel III, are, in the case of each of clause (i) and clause (ii) above, deemed to have been introduced or adopted after the date hereof, regardless of the date enacted, adopted, issued, promulgated or implemented.

(e)    Failure or delay on the part of any Affected Person to demand compensation pursuant to this Section shall not constitute a waiver of such Affected Person’s right to demand such compensation; provided that the Seller shall not be required to compensate an Affected Person pursuant to this Section for any increased costs or reductions incurred more than 180 days prior to the date that such Affected Person, as the case may be, notifies the Seller of the occurrence or event giving rise to such increased costs or reductions and of such Affected Person’s intention to claim compensation therefor; provided further that, if the occurrence or event giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof.

(i)    does or shall subject such Affected Person to any tax of any kind whatsoever with respect to this Agreement, any increase in the Purchased Interest or any portion thereof or in the amount of such Person’s Investment relating thereto, or does or shall change the basis of taxation of payments to such Affected Person on account of

741604250 99551574    13

(ii)    does or shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, or deposits or other liabilities in or for the account of, purchases, advances or loans by, or other credit extended by, or any other acquisition of funds by, any office of such Affected Person that are not otherwise included in the determination of the Euro-Rate, the LMIRapplicableBenchmarkor the Base Rate hereunder, or

(iii)    does or shall impose on such Affected Person any other condition,

and the result of any of the foregoing is: (A) to increase the cost to such Affected Person of acting as Administrator or as a Purchaser Agent, or of agreeing to purchase or purchasing or maintaining the ownership of undivided percentage ownership interests with regard to the Purchased Interest (or interests therein) or any Portion of Investment, or (B) to reduce any amount receivable hereunder (whether directly or indirectly), then, in any such case, upon demand by such Affected Person, the Seller shall promptly pay to such Affected Person additional amounts necessary to compensate such Affected Person for such additional cost or reduced amount receivable. All such amounts shall be payable as incurred. A certificate from such Affected Person to the Seller and the Administrator certifying, in reasonably specific detail, the basis for, calculation of, and amount of such additional costs or reduced amount receivable shall be conclusive and binding for all purposes, absent manifest error; provided, however, that no Affected Person shall be required to disclose any confidential or tax planning information in any such certificate; provided, further, however, that notwithstanding anything to the contrary, for purposes of this Section 1.8, (i) the Dodd-Frank Wall Street Reform and Consumer Protection Act, and all requests, rules, guidelines and directives promulgated thereunder, and (ii) all requests, rules, guidelines or directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or any Governmental Authority, any central bank of any jurisdiction, comparable agency or other Person, in each case pursuant to, or implementing, the accord know as Basel II or Basel III, are, in the case of each of clause (i) and clause (ii) above, deemed to have been introduced or adopted after the date hereof, regardless of the date enacted, adopted, issued, promulgated or implemented.

Section 1.9.    Inability to Determine Euro-Rate or LMIR.

(a)    IfSubject to Section 1.12, ifthe Administrator (or any Purchaser Agent) determines before the first day of any Yield Period (which determination shall be final and conclusive) that, by reason of circumstances affecting the interbank eurodollar market (in respect of such Person’s Purchaser Group or otherwise), deposits in dollars (in the relevant amounts for such Yield Period) are not being offered to such Person in the interbank eurodollar market for such Yield Period, or adequate means do not exist for ascertaining the Euro-Rate or theLMIR for such Yield Period, then the Administrator or such Purchaser Agent shall give notice thereof to the Seller. Thereafter, until the Administrator or such Purchaser Agent notifies the Seller that the circumstances giving rise to such suspension no longer exist, no Portion of Investment shall be funded by reference to the Euro-Rate or theLMIR and the Discount for any outstanding Portions of Investment then funded by reference to the Euro-Rate or theLMIR shall, on the last day of the then current Yield Period, be converted to the rate determined by reference to the Base Rate.

(b)    IfSubject to Section 1.12, if, on or before the first day of any Yield Period, the Administrator shall have been notified by any Purchaser, Purchaser Agent or Liquidity Provider that, such Person has determined (which determination shall be final and conclusive) that, any enactment, promulgation or adoption of or any change in any Applicable Law, or any change in the interpretation or administration thereof by a governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by such Person with any guideline, request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for such Person to fund or maintain any Portion of Investment at an interest rate based upon theEuro-Rate or theLMIR, the Administrator shall notify the Seller thereof. Upon receipt of such notice, until the Administrator notifies the Seller that the circumstances giving rise to such determination no longer apply, (a) no Portion of Investment shall be funded at the rate determined by reference to the Euro-Rate or theLMIR and (b) the Discount for any such outstanding Portions of Investment shall be converted to a rate determined by reference to the Base Rate either on the last day of the then current Yield Period if such Person may lawfully continue to maintain such Portion of Investment by reference to the Euro-Rate or theLMIR to such day, or immediately, if such Person may not lawfully continue to maintain such Portion of Investment by reference to the Euro-Rate or theLMIR to such day.

Section 1.10. Extension of Termination Date. The Seller may advise the Administrator and each Committed Purchaser in writing of its desire to extend the Scheduled Commitment Termination Date with respect to such Purchaser; provided that such request is made not more than one-hundred twenty (120) days prior to, and not less than sixty (60) days prior to, the then current Scheduled Commitment Termination Date with respect to such Purchaser. In the event that the applicable Purchaser is agreeable to such extension, the Administrator shall so notify the Seller in writing (itbeingunderstood that the Purchasers may accept or decline such a request in their sole discretion and on such terms as they may elect) not less than 30 days prior to its then current Scheduled Commitment Termination Date and the Seller, the Administrator, the Purchaser Agents and the Purchasers shall enter into such documents as the Purchasers may deem necessary or appropriate to reflect such extension, and all reasonable costs and expenses incurred by the Purchasers, the Administrator and the Purchaser Agents in connection therewith

741604250 99551574    15

(including reasonable Attorney Costs) shall be paid by the Seller. In the event a Purchaser declines the request for such extension, the Administrator shall so notify the Seller and each Purchaser Agent of such determination; provided, however, that the failure of the Administrator to notify the Seller of the determination to decline such extension shall not affect the understanding and agreement that the Purchaser shall be deemed to have refused to grant the requested extension in the event the Administrator fails to affirmatively notify the Seller, in writing, of their agreement to accept the requested extension.

Section 1.11.    Increase in Commitments.

(a)    Requests for Increase. So long as no Termination Event or Unmatured Termination Event has occurred and is continuing, upon notice to the Administrator and each Purchaser Agent, the Servicer (on behalf of the Seller) may from time to time (i) request an increase in the Commitment with respect to any existing Committed Purchaser (with the consent of the Administrator) or (ii) request that additional Persons be added as Committed Purchasers subject to the provisions of Section 1.2(e), in each case at any time following the Closing Date and prior to the Facility Termination Date (it being understood and agreed that, for the avoidance of doubt, at no time shall the aggregate of all Commitments exceed $1,400,000,0001,500,000,000); provided, that each request for an increase or addition of a Person pursuant to Section 1.2(e) shall be in a minimum amount of $10,000,000 and increments of $5,000,000 above such minimum amount. At the time of sending such notice with respect to any existing Committed Purchaser, the Servicer (in consultation with the Administrator and the Purchaser Agent related to such Committed Purchaser) shall specify the time period within which such Committed Purchaser and the Administrator are requested to respond to the Servicer’s request (which shall in no event be less than ten (10) Business Days from the date of delivery of such notice to the Administrator and such Committed Purchaser and its related Purchaser Agent). For the avoidance of doubt, any increase in the Commitment of any Committed Purchaser is at the sole discretion of such Committed Purchaser.

(b)    Elections to Increase. In respect of any existing Committed Purchaser, each of such Committed Purchaser being asked to increase its Commitment and the Administrator shall notify the Seller and the Servicer within the applicable time period whether or not such Person agrees, in its respective sole discretion, to the increase to such Committed Purchaser’s Commitment. Any such Person not responding within such time period shall be deemed to have declined to consent to an increase in such Committed Purchaser’s Commitment. For the avoidance of doubt, only the consent of the Committed Purchaser then being asked to increase its Commitment and the Administrator shall be required in order to approve any such request.

(c)    Effective Date. If the Commitment of any existing Committed Purchaser is increased in accordance with this Section 1.11, the Administrator and the Purchaser Agent for such Committed Purchaser shall determine the effective date with respect to such increase (such date, the “Commitment Increase Effective Date”).

(d)    Notification by the Administrator. The Administrator shall notify each Purchaser Agent, the Seller and the Servicer of the Administrator’s and such Committed

(f)    Conflicting Provisions. This Section 1.11 shall supersede any provisions in Section 6.1 to the contrary.

Section 1.12.    Successor Euro-Rate or LMIRUSD LIBOR.

(a)    Benchmark Replacement. Notwithstanding anything to the contrary herein or in any other Transaction Document, if the Administrator determines thata Benchmark Transition Event or an Early Opt-in Event has occurred with respect to Euro-Rate or LMIR, theAdministrator and the Seller may amend this Agreement to replace Euro-Rate or LMIR, asapplicable, with a Benchmark Replacement; and any such amendment will become effectiveatElection, as applicable, and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any setting of the then-current Benchmark, then (x) if a Benchmark Replacement is determined in accordance with clause (1) or (2) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Transaction Document in respect of such Benchmark setting and subsequent Benchmark settings without any amendment to, or further action or consent of any other party to, this Agreement or any other Transaction Document and (y) if a Benchmark Replacement is determined in accordance with clause (3) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Transaction Document in respect of any Benchmark setting at or after5:00 p.m. (New York City time) on the fifth (5th) Business Day after the Administrator has provided such proposedamendment to all Purchasers,date notice of such Benchmark Replacement is provided to the Purchaser Agents and Seller without any amendment to, or further action or consent of any other party to, this Agreement or any other Transaction Documentso long as the Administrator has not received, by such time, written notice of objection to such amendment from PurchaserscompromisingBenchmark Replacement from Purchaser Agents comprisingthe Majority

741604250 99551574                17

Purchasers.Until the Benchmark Replacement with respect to Euro-Rate or LMIR, as applicable, is effective, each advance, conversion and renewal of an Investment bearing interest by reference to Euro-Rate or LMIR, as applicable, will continue to bear interest with reference to Euro-Rate or LMIR (as the case may be); provided, however, that during a Benchmark Unavailability Period (i) any pending selection of, conversion to or renewal of an Investment bearing interest by reference to Euro-Rate or LMIR that has not yet gone into effect shall be deemed to be a selection of, conversion to or renewal of the Base Rate with respect to such Investment, and such Investment shall bear interest by reference to the Base Rate (rather than by reference to Euro-Rate or LMIR), (ii) all outstanding Investments bearing interest by reference to Euro-Rate or LMIR shall automatically be converted to bear interest by reference to the Base Rate at the expiration of the existing Yield Period (or sooner, if Administrator cannot continue to lawfully maintain such affected Investment bearing interest by reference to Euro-Rate or LMIR, as applicable) and (iii) the component of the Base Rate based upon LMIR will not be used in any determination of the Base Rate. (b)

741604250 99551574                18

announcing that any tenor for such Benchmark is or will be no longer representative, then the Administrator may modify the definition of “Yield Period” for any Benchmark settings at or after such time to remove such unavailable or non-representative tenor and (ii) if a tenor that was removed pursuant to clause (i) above either (A) is subsequently displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (B) is not, or is no longer, subject to an announcement that it is or will no longer be representative for a Benchmark (including a Benchmark Replacement), then the Administrator may modify the definition of “Yield Period” for all Benchmark settings at or after such time to reinstate such previously removed tenor.

(f)    Secondary Term SOFR Conversion. Notwithstanding anything to the contrary herein or in any other Transaction Document and subject to the proviso below in this paragraph, if a Term SOFR Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any setting of the then-current Benchmark, then (i) the applicable Benchmark Replacement will replace the then-current Benchmark for all purposes hereunder or under any Transaction Document in respect of such Benchmark setting (the “Secondary Term SOFR Conversion Date”) and subsequent Benchmark settings, without any amendment to, or further action or consent of any other party to, this Agreement or any other Transaction Document; and (ii) Investments outstanding on the Secondary Term SOFR Conversion Date bearing interest based on the then-current Benchmark shall be deemed to have been converted to Investments bearing interest at the Benchmark Replacement with a tenor approximately the same length as the interest payment period of the then-current Benchmark; provided that, this paragraph (f) shall not be effective unless the Administrator has delivered to the Purchaser Agents and the Seller a Term SOFR Notice.

Accounting Policies [Abstract]

ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements of WESCO have been prepared in accordance with Rule 10-01 of Regulation S-X of the Securities and Exchange Commission (the “SEC”). The unaudited condensed consolidated financial information should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in WESCO’s 2020 Annual Report on Form 10-K as filed with the SEC on March 1, 2021. The Condensed Consolidated Balance Sheet at December 31, 2020 was derived from the audited Consolidated Financial Statements as of that date, but does not include all of the disclosures required by accounting principles generally accepted in the United States of America.

The unaudited Condensed Consolidated Balance Sheet as of June 30, 2021, the unaudited Condensed Consolidated Statements of Income (Loss) and Comprehensive Income (Loss), the unaudited Condensed Consolidated Statements of Stockholders' Equity for the three and six months ended June 30, 2021 and 2020, and the unaudited Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2021 and 2020, respectively, in the opinion of management, have been prepared on the same basis as the audited Consolidated Financial Statements and include all adjustments necessary for the fair statement of the results of the interim periods presented herein. All adjustments reflected in the unaudited condensed consolidated financial information are of a normal recurring nature unless indicated. The results for the interim periods presented herein are not necessarily indicative of the results to be expected for the full year.

Prior to the completion of its merger with Anixter International Inc. ("Anixter") on June 22, 2020, as described in Note 4, "Acquisitions and Disposals", WESCO had four operating segments that had been aggregated as one reportable segment. Effective on the date of acquisition, the Company added Anixter as a separate reportable segment for the quarterly period ended June 30, 2020. At the beginning of the third quarter of 2020, the Company identified new operating segments organized around three strategic business units consisting of EES, CSS and UBS. These operating segments are equivalent to the Company's reportable segments. The operating segments in the respective periods were determined in accordance with the manner in which WESCO's chief operating decision maker ("CODM") reviewed financial information during those periods. The financial information used by the CODM to evaluate the performance of the Company's operating segments is disclosed in Note 13, "Business Segments". The applicable comparative financial information reported in the Company's previously issued interim financial statements for the three and six months ended June 30, 2020 has been recast in this Quarterly Report on Form 10-Q to conform to the basis of the new segments.

Reclassifications

For the three and six months ended June 30, 2020, $0.7 million and $0.8 million, respectively, of other non-operating income has been reclassified from "net interest and other" to "other income, net" in the unaudited Condensed Consolidated Statements of Loss and Comprehensive Loss. For the six months ended June 30, 2020, stock-based compensation of $9.5 million and amortization of debt discount and debt issuance costs of $2.1 million have been reclassified from other operating activities in the unaudited Condensed Consolidated Statement of Cash Flows. These reclassifications have been made to conform to the current period presentation.

Change in Estimates

During the second quarter of 2021, the Company established a new corporate brand strategy that will result in migrating certain legacy WESCO sub-brands to a master brand architecture. The Company accounts for the trademarks associated with these sub-brands as intangible assets. As of December 31, 2020, $39.1 million of the trademarks impacted by the master brand strategy had indefinite lives and $9.5 million had remaining estimated useful lives ranging from 3 to 8 years. The Company continually evaluates whether events or circumstances have occurred that would require a change to the estimated useful lives of indefinite-lived and definite lived intangible assets. When such a change is warranted, the remaining carrying amount of the intangible asset is amortized prospectively over the revised remaining useful life. Accordingly, during the second quarter of 2021, the Company changed the estimated useful lives of the trademarks affected by the new corporate brand strategy to coincide with the expected period of time to migrate such sub-brands to the master brand architecture. The Company assigned remaining estimated useful lives to these trademarks, including those that previously had indefinite lives, ranging from less than one year to 5 years. The Company assessed these intangible assets for impairment prior to amortizing them over their revised estimated remaining useful lives. No impairment losses were identified as a result of these tests.

Recently Adopted Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which removes certain exceptions to the general principles of Accounting Standards Codification Topic 740, Income Taxes, and simplifies other aspects of accounting for income taxes. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted in any interim or annual period, with any adjustments reflected as of the beginning of the fiscal year of adoption. The Company adopted this ASU in the first quarter of 2021. The adoption of this guidance did not have a material impact on the consolidated financial statements and notes thereto presented herein.

Recently Issued Accounting Pronouncements

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this Update are effective for all entities as of March 12, 2020 through December 31, 2022. Management is currently evaluating the impact related to the replacement of London Interbank Offered Rate (LIBOR) and whether the Company will elect the adoption of the optional guidance.

Other pronouncements issued by the FASB or other authoritative accounting standards groups with future effective dates are either not applicable or are not expected to be significant to WESCO’s financial position, results of operations or cash flows.

(1)    No individual other international country's net sales are material.

(2)    WESCO attributes revenues from external customers to individual countries on the basis of point of sale.

In accordance with certain contractual arrangements, WESCO receives payment from its customers in advance and recognizes such payment as deferred revenue. Revenue for advance payment is recognized when the performance obligation has been satisfied and control has transferred to the customer, which is generally upon shipment. Deferred revenue is usually recognized within a year or less from the date of the customer’s advance payment. At June 30, 2021 and December 31, 2020, $43.0 million and $24.3 million, respectively, of deferred revenue was recorded as a component of other current liabilities in the Condensed Consolidated Balance Sheets.

WESCO’s revenues are adjusted for variable consideration, which includes customer volume rebates, returns, and discounts. WESCO measures variable consideration by estimating expected outcomes using analysis and inputs based upon historical data as well as current and forecasted information. Variable consideration is reviewed by management on a monthly basis and revenue is adjusted accordingly. Variable consideration reduced revenue for the three months ended June 30, 2021 and 2020 by approximately $112.4 million and $31.7 million, respectively, and by approximately $217.8 million and $54.9 million for the six months ended June 30, 2021 and 2020, respectively. As of June 30, 2021 and December 31, 2020, the Company's estimated product return obligation was $39.6 million and $38.9 million, respectively.

Shipping and handling activities are recognized in net sales when they are billed to the customer. WESCO has elected to recognize shipping and handling costs as a fulfillment cost. Shipping and handling costs recorded as a component of selling, general and administrative expenses totaled $62.7 million and $20.9 million for the three months ended June 30, 2021 and 2020, respectively, and $116.0 million and $38.9 million for the six months ended June 30, 2021 and 2020, respectively

Business Combinations [Abstract]

Business Combination Disclosure

Anixter International Inc.

On June 22, 2020, WESCO completed its acquisition of Anixter, a Delaware corporation. Pursuant to the terms of the Agreement and Plan of Merger, dated January 10, 2020 (the “Merger Agreement”), by and among Anixter, WESCO and Warrior Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of WESCO (“Merger Sub”), Merger Sub was merged with and into Anixter (the “Merger”), with Anixter surviving the Merger and continuing as a wholly owned subsidiary of WESCO. On June 23, 2020, Anixter merged with and into Anixter Inc., with Anixter Inc. surviving to become a wholly owned subsidiary of WESCO.

The Company used the net proceeds from the issuance of senior unsecured notes, borrowings under its revolving credit and accounts receivable securitization facilities, as well as cash on hand, to finance the acquisition of Anixter and related transaction costs.

At the effective time of the Merger, each outstanding share of common stock of Anixter (subject to limited exceptions) was converted into the right to receive (i) $72.82 in cash, (ii) 0.2397 shares of common stock of WESCO, par value $0.01 per share (the “WESCO Common Stock”) and (iii) 0.6356 depositary shares, each representing a 1/1,000th interest in a share of newly issued fixed-rate reset cumulative perpetual preferred stock of WESCO, Series A, with a $25,000 stated amount per whole preferred share and an initial dividend rate equal to 10.625%.

Anixter was a leading distributor of network and security solutions, electrical and electronic solutions, and utility power solutions with locations in over 300 cities across approximately 50 countries, and 2019 annual sales of more than $8 billion. The Merger brought together two companies with highly compatible capabilities and characteristics. The combination of WESCO and Anixter created an enterprise with scale and should afford the Company the opportunity to digitize its business, and expand its services portfolio and supply chain offerings.

The total fair value of consideration transferred for the Merger consisted of the following:

	(In thousands)
Cash portion attributable to common stock outstanding	$	2,476,010
Cash portion attributable to options and restricted stock units outstanding	87,375
Fair value of cash consideration	2,563,385
Common stock consideration	313,512
Series A preferred stock consideration	573,786
Fair value of equity consideration	887,298
Extinguishment of Anixter obligations, including accrued and unpaid interest	1,247,653
Total purchase consideration	$	4,698,336
Supplemental cash flow disclosure related to acquisitions:
Cash paid for acquisition	$	3,811,038
Less: Cash acquired	(103,463)
Cash paid for acquisition, net of cash acquired	$	3,707,575

The Merger was accounted for as a business combination with WESCO acquiring Anixter in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations. Under the acquisition method of accounting, the purchase consideration was allocated to the identified assets acquired and liabilities assumed based on their respective acquisition date fair value, with any excess allocated to goodwill. The fair value estimates were based on income, market and cost valuation methods using primarily unobservable inputs developed by management, which are categorized as Level 3 in the fair value hierarchy. Specifically, the fair values of the identified trademark and customer relationship intangible assets were estimated using the relief-from-royalty and multi-period excess earnings methods, respectively. Significant inputs used to value these identifiable intangible assets included projected revenues and expected operating margins, customer attrition rates, discount rates, royalty rates, and applicable income tax rates. The excess purchase consideration recorded to goodwill is not deductible for income tax purposes, and has been assigned to the Company's reportable segments based on their relative fair values, as disclosed in Note 5, "Goodwill and Intangible Assets". The resulting goodwill is primarily attributable to Anixter's workforce, significant cross-selling opportunities in additional geographies, enhanced scale, and other operational efficiencies.

During the second quarter of 2021, the Company finalized its allocation of the purchase consideration to the respective fair values of assets acquired and liabilities assumed in the acquisition of Anixter. As the Company obtained additional information during the measurement period (one year from the acquisition date), it recorded adjustments to its preliminary estimates of fair value, which are presented in the table below. The net impact of these adjustments was an increase to goodwill of $13.4 million in the second quarter of 2021 and $16.4 million since the Company's initial estimate.

The following table sets forth the allocation of the purchase consideration to the respective fair value of assets acquired and liabilities assumed for the acquisition of Anixter:

These amounts excluded the financial results of WESCO's legacy utility and data communications businesses in Canada, which were divested in the first quarter of 2021 under a Consent Agreement with the Competition Bureau of Canada, as described below.

Canadian Divestitures

On August 6, 2020, the Company entered into a Consent Agreement with the Competition Bureau of Canada regarding the merger with Anixter. Under the Consent Agreement, the Company was required to divest certain legacy WESCO utility and data communications businesses in Canada. In February 2021, the Company completed such divestitures for cash consideration totaling $54.3 million. The Company recognized a net gain from the sale of these businesses of $8.9 million, which is reported as a component of selling, general and administrative expenses for the six months ended June 30, 2021. These sales fulfilled the Company’s divestiture commitments under the Consent Agreement and the net cash proceeds were used to repay debt.

STOCK-BASED COMPENSATION (Notes)

6 Months Ended

Jun. 30, 2021

Share-based Payment Arrangement [Abstract]

STOCK-BASED COMPENSATION

WESCO sponsors a stock-based compensation plan. On May 27, 2021, the Company's stockholders approved the WESCO International, Inc. 2021 Omnibus Incentive Plan (the “2021 Plan”). The 2021 Plan is administered by the Compensation Committee of the Company's Board of Directors.

The 2021 Plan was designed to be the successor plan to all prior stock-based compensation plans. Accordingly, no new awards may be granted under the Company’s 1999 Long-Term Incentive Plan, as amended and restated (the “1999 Plan”) or any other prior plan. Awards outstanding under any such prior plans will remain in full force and effect under such plans according to their respective terms. To the extent that any such award is forfeited, terminates, expires or lapses without being exercised, or is settled for cash, the shares subject to such award not delivered will again be available for awards under the 2021 Plan.

The maximum number of shares of the Company’s common stock that may be granted pursuant to awards under the 2021 Plan is 2,150,000, less any shares issued under the 1999 Plan after March 31, 2021 and until the annual stockholders meeting in May 2021. If any award granted under the 2021 Plan is forfeited, terminates, expires or lapses instead of being exercised, or is settled for cash, the shares subject to such award will again be available for grant under the 2021 Plan. Shares delivered by participants or withheld by the Company to pay all or a portion of the exercise price or withholding taxes with respect to stock option or stock appreciation right awards will not again be available for issuance. Shares delivered by participants or withheld by the Company to satisfy applicable tax withholding obligations with respect to a full-value award (i.e., restricted shares or restricted stock units) will again be available for grant under the 2021 Plan.

WESCO’s stock-based employee compensation awards outstanding under the 1999 Plan are comprised of stock-settled stock appreciation rights, restricted stock units and performance-based awards. Compensation cost for all stock-based awards is measured at fair value on the date of grant and compensation cost is recognized, net of estimated forfeitures, over the service period for awards expected to vest. The fair value of stock-settled stock appreciation rights is determined using the Black-Scholes model. The fair value of restricted stock units and performance-based awards with performance conditions is determined by the grant-date closing price of WESCO’s common stock. The forfeiture assumption is based on WESCO’s historical employee behavior that is reviewed on an annual basis. No dividends are assumed. For stock-settled stock appreciation rights that are exercised and for restricted stock units and performance-based awards that vest, shares are issued out of WESCO's outstanding common stock.

Stock-settled stock appreciation rights vest ratably over a three-year period and terminate on the tenth anniversary of the grant date unless terminated sooner under certain conditions. Restricted stock unit awards granted in February 2020 and prior vest based on a minimum time period of three years. The special award described below vests in tranches. Restricted stock units awarded in 2021 vest ratably over a three-year period on each of the first, second and third anniversaries of the grant date. Vesting of performance-based awards is based on a three-year performance period, and the number of shares earned, if any, depends on the attainment of certain performance levels. Outstanding awards would vest upon the consummation of a change in control transaction and performance-based awards would vest at the target level.

On July 2, 2020, a special award of restricted stock units was granted to certain officers of the Company. These awards vest in tranches of 30% on each of the first and second anniversaries of the grant date and 40% on the third anniversary of the grant date, subject, in each case, to continued employment through the applicable anniversary date.

Performance-based awards granted in 2021, 2020 and 2019 were based on two equally-weighted performance measures: the three-year average growth rate of WESCO's net income and the three-year cumulative return on net assets.

During the three and six months ended June 30, 2021 and 2020, WESCO granted the following stock-settled stock appreciation rights, restricted stock units and performance-based awards at the following weighted-average fair values:

	Three Months Ended				Six Months Ended
	June 30, 2021		June 30, 2020		June 30, 2021		June 30, 2020
Stock-settled stock appreciation rights granted	3,398		—		139,592		262,091
Weighted-average fair value	$	38.62	$	—	$	33.19	$	13.86

Weighted-average fair value	$	86.91	$	—	$	77.12	$	48.32
Performance-based awards granted	3,020		—		122,812		158,756
Weighted-average fair value	$	86.91	$	—	$	76.76	$	48.67

The fair value of stock-settled stock appreciation rights was estimated using the following weighted-average assumptions:

	Three Months Ended			Six Months Ended
	June 30, 2021		June 30, 2020	June 30, 2021		June 30, 2020
Risk free interest rate	1.3	%	n/a	0.8	%	1.4	%
Expected life (in years)	7		n/a	7		5
Expected volatility	42	%	n/a	41	%	30	%

The risk-free interest rate is based on the U.S. Treasury Daily Yield Curve as of the grant date. The expected life is based on historical exercise experience and the expected volatility is based on the volatility of the Company's daily stock price over the expected life preceding the grant date of the award.

The following table sets forth a summary of stock-settled stock appreciation rights and related information for the six months ended June 30, 2021:

	Awards	Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (In years)	Aggregate Intrinsic Value (In thousands)
Outstanding at December 31, 2020	2,161,556	$	60.48
Granted	139,592	77.05

Exercisable at June 30, 2021	1,359,501	$	64.73	5.1	$	53,041

For the six months ended June 30, 2021, the aggregate intrinsic value of stock-settled stock appreciation rights exercised during such period was $24.9 million.

The following table sets forth a summary of time-based restricted stock units and related information for the six months ended June 30, 2021:

	Awards	Weighted- Average Fair Value
Unvested at December 31, 2020	921,495	$	43.15
Granted	307,583	77.12
Vested	(226,943)	43.89
Forfeited	(25,134)	59.90
Unvested at June 30, 2021	977,001	$	53.23

The following table sets forth a summary of performance-based awards for the six months ended June 30, 2021:

	Awards	Weighted- Average Fair Value
Unvested at December 31, 2020	305,269	$	52.61
Granted	122,812	76.76
Vested	(22,371)	62.34
Forfeited	(27,802)	59.87
Unvested at June 30, 2021	377,908	$	59.35

Vesting of the 377,908 shares of performance-based awards in the table above is dependent upon the achievement of certain performance targets, including half that are dependent upon the three-year average growth rate of WESCO's net income and the other half that are based upon the three-year cumulative return on net assets. These awards are accounted for as awards with performance conditions; compensation cost is recognized over the performance period based upon WESCO's determination of whether it is probable that the performance targets will be achieved.

WESCO recognized $7.2 million and $4.9 million of non-cash stock-based compensation expense, which is included in selling, general and administrative expenses, for the three months ended June 30, 2021 and 2020, respectively. WESCO recognized $13.2 million and $9.5 million of non-cash stock-based compensation expense, which is included in selling, general and administrative expenses, for the six months ended June 30, 2021 and 2020, respectively. As of June 30, 2021, there was $55.3 million of total unrecognized compensation expense related to non-vested stock-based compensation arrangements for all awards previously made of which approximately $14.8 million is expected to be recognized over the remainder of 2021, $23.9 million in 2022, $15.2 million in 2023 and $1.4 million in 2024.

EARNINGS PER SHARE

Jun. 30, 2021

Earnings Per Share [Abstract]

EARNINGS PER SHARE

Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding during the periods. Diluted earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average common shares and common share equivalents outstanding during the periods. The dilutive effect of common share equivalents is considered in the diluted earnings per share computation using the treasury stock method, which includes consideration of equity awards.

The following table sets forth the details of basic and diluted earnings (loss) per share:

	Three Months Ended				Six Months Ended

Diluted	$	2.02	$	(0.84)	$	2.89	$	(0.03)

For the three and six months ended June 30, 2021, the computation of diluted earnings per share attributable to common stockholders excluded stock-based awards of approximately 0.1 million. For the three and six months ended June 30, 2020, the computation of diluted loss per share attributable to common stockholders excluded stock-based awards of approximately 3.0 million and 2.8 million, respectively. These amounts were excluded because their effect would have been antidilutive.

Accounts Receivable Securitization Facility

On June 1, 2021, WESCO Distribution amended its accounts receivable securitization facility (the “Receivables Facility”) pursuant to the terms and conditions of a Third Amendment to the Fifth Amended and Restated Receivables Purchase Agreement (the “Receivables Amendment”), by and among WESCO Receivables Corp. (“WESCO Receivables”), WESCO Distribution, the various purchaser groups from time to time party thereto and PNC Bank, National Association, as Administrator. The Receivables Amendment amends the amended and restated receivables purchase agreement entered into on June 22, 2020 (the “Receivables Purchase Agreement”). The Receivables Amendment, among other things, increased the purchase limit under the Receivables Purchase Agreement from $1,200 million to $1,300 million, extended the maturity date from June 22, 2023 to June 21, 2024, decreased the LIBOR floor from 0.50% to 0.00% and decreased the interest rate spread from 1.20% to 1.15%. The commitment fee of the Receivables Facility remained unchanged.

Under the Receivables Facility, WESCO sells, on a continuous basis, an undivided interest in all domestic accounts receivable to WESCO Receivables, a wholly owned special purpose entity (the “SPE”). The SPE sells, without recourse, a senior undivided interest in the receivables to financial institutions for cash while maintaining a subordinated undivided interest in the receivables, in the form of overcollateralization. Since WESCO maintains control of the transferred receivables, the transfers do not qualify for “sale” treatment. As a result, the transferred receivables remain on the balance sheet, and WESCO recognizes the related secured borrowing. WESCO has agreed to continue servicing the sold receivables for the third-party conduits and financial institutions at market rates; accordingly, no servicing asset or liability has been recorded.

5.375% Senior Notes due 2021

In November 2013, WESCO Distribution issued $500 million aggregate principal amount of 5.375% Senior Notes due 2021 (the "2021 Notes") through a private offering exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). The 2021 Notes were issued at 100% of par and were governed by an indenture (the “2021 Indenture”) entered into on November 26, 2013 between WESCO International and U.S. Bank National Association, as trustee. The 2021 Notes were unsecured senior obligations of WESCO Distribution and were guaranteed on a senior unsecured basis by WESCO International. The 2021 Notes had a stated interest rate of 5.375% per annum, payable semi-annually in arrears on June 15 and December 15 of each year. The 2021 Notes had a maturity date of December 15, 2021 and were redeemable in whole or in part at any time. The net proceeds of the 2021 Notes were used to prepay a portion of the U.S. sub-facility of the then outstanding term loan due 2019.

Under the terms of a registration rights agreement dated as of November 26, 2013 among WESCO Distribution, WESCO International and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as the representative of the initial purchasers of the 2021 Notes, WESCO Distribution and WESCO International agreed to register under the Securities Act notes having terms identical in all material respects to the 2021 Notes (the “2021 Exchange Notes”) and to make an offer to exchange the 2021 Exchange Notes for the 2021 Notes. WESCO Distribution launched the exchange offer on June 12, 2014 and the exchange offer expired on July 17, 2014.

On December 15, 2020, WESCO Distribution exercised its right to redeem the entire $500 million aggregate principal amount of the 2021 Notes, and U.S. Bank, National Association, as trustee under the 2021 Indenture, issued a notice of redemption to registered holders of the 2021 Notes.

On January 14, 2021, WESCO Distribution redeemed the $500 million aggregate principal amount of the 2021 Notes at a redemption price equal to 100% of the principal amount plus accrued interest to, but not including, January 14, 2021. The redemption of the 2021 Notes was funded with available cash, as well as borrowings under the Company's accounts receivable securitization and revolving credit facilities. The Company recognized a loss of $1.0 million from the redemption of the 2021 Notes resulting from the the write-off of unamortized debt issuance costs, which is recorded as a component of interest expense, net in the Condensed Consolidated Statement of Income and Comprehensive Income for the six months ended June 30, 2021.

5.375% Senior Notes due 2024

In June 2016, WESCO Distribution issued $350 million aggregate principal amount of 5.375% Senior Notes due 2024 (the "2024 Notes") through a private offering exempt from the registration requirements of the Securities Act. The 2024 Notes were issued at 100% of par and are governed by an indenture (the “2024 Indenture”) entered into on June 15, 2016 among WESCO Distribution, as issuer, WESCO International, as parent guarantor, and U.S. Bank National Association, as trustee. The 2024 Notes are unsecured senior obligations of WESCO Distribution and are guaranteed on a senior unsecured basis by WESCO International. The 2024 Notes bear interest at a stated rate of 5.375% per annum, payable semi-annually in arrears on June 15 and December 15 of each year. The 2024 Notes mature on June 15, 2024. The Company used the net proceeds to redeem its 6.0% Convertible Senior Debentures due 2029.

Under the terms of a registration rights agreement dated as of June 15, 2016 among WESCO Distribution, as the issuer, WESCO International, as parent guarantor, and Goldman, Sachs & Co., as representative of the initial purchasers of the 2024 Notes, WESCO Distribution and WESCO International agreed to register under the Securities Act notes having terms identical in all material respects to the 2024 Notes (the “2024 Exchange Notes”) and to make an offer to exchange the 2024 Exchange Notes for the 2024 Notes. WESCO Distribution launched the exchange offer on December 28, 2016 and the exchange offer expired on January 31, 2017.

On June 2, 2021, WESCO Distribution exercised its right to redeem the entire $350 million aggregate principal amount of the 2024 Notes, and U.S. Bank, National Association, as trustee under the 2024 Indenture, issued a notice of redemption to registered holders of the 2024 Notes. The date fixed for the redemption of the 2024 Notes is July 2, 2021. Accordingly, the 2024 Notes are classified as a component of short-term debt and current portion of long-term debt in the Condensed Consolidated Balance Sheet as of June 30, 2021. The 2024 Notes will be redeemed at a redemption price equal to 101.344% of the principal amount of the 2024 Notes plus accrued interest on the 2024 Notes to, but not including, July 2, 2021.

Retirement Benefits [Abstract]

EMPLOYEE BENEFIT PLANS

9. EMPLOYEE BENEFIT PLANS

Defined Contribution Plans

WESCO Distribution sponsors a defined contribution retirement savings plan for the majority of its U.S. employees. The Company matches contributions made by employees at an amount equal to 50% of participants' total monthly contributions up to 6% of eligible compensation. Contributions are made in cash and employees have the option to transfer balances allocated to their accounts into any of the available investment options. The Company may also make, subject to the Board of Directors' approval, a discretionary contribution to the defined contribution retirement savings plan covering U.S. participants if certain predetermined profit levels are attained.

WESCO Distribution Canada LP, a wholly-owned subsidiary of the Company, sponsors a defined contribution plan for certain Canadian employees. The Company makes contributions in amounts ranging from 3% to 5% of participants' eligible compensation based on years of continuous service.

Anixter Inc. sponsors a defined contribution plan covering all of its non-union U.S. employees (the "Anixter Employee Savings Plan"). The employer match for the Anixter Employee Savings Plan is equal to 50% of a participant's contribution up to 5% of the participant's compensation. Anixter Inc. will also make an annual contribution to the Anixter Employee Savings Plan on behalf of each active participant who is hired or rehired on or after July 1, 2015, or is not participating in the Anixter Inc. Pension Plan. The amount of the employer annual contribution is equal to either 2% or 2.5% of the participant’s compensation, as determined by the participant’s years of service. This contribution is in lieu of being eligible for the Anixter Inc. Pension Plan. Certain of Anixter Inc.'s foreign subsidiaries also have defined contribution plans. Contributions to these plans are based upon various levels of employee participation and legal requirements.

WESCO incurred charges of $16.1 million and $3.4 million for the three months ended June 30, 2021 and 2020, respectively, and $32.7 million and $9.1 million for the six months ended June 30, 2021 and 2020, respectively, for all defined contribution plans.

Deferred Compensation Plans

WESCO Distribution sponsors a non-qualified deferred compensation plan (the "WESCO Deferred Compensation Plan") that permits select employees to make pre-tax deferrals of salary and bonus. Employees have the option to transfer balances allocated to their accounts in the WESCO Deferred Compensation Plan into any of the available investment options. The WESCO Deferred Compensation Plan is an unfunded plan. As of June 30, 2021, the Company's obligation under the WESCO Deferred Compensation Plan was $19.3 million, which was included in other noncurrent liabilities in the Condensed Consolidated Balance Sheet. As of December 31, 2020, the Company's obligation under the WESCO Deferred Compensation Plan was $27.4 million, of which $10.1 million was included in other current liabilities and $17.3 million was in other noncurrent liabilities in the Condensed Consolidated Balance Sheet.

Anixter Inc. sponsored a non-qualified deferred compensation plan (the "Anixter Deferred Compensation Plan") that permitted select employees to make pre-tax deferrals of salary and bonus. Interest was accrued monthly on the deferred compensation balances based on the average ten-year Treasury note rate for the previous three months times a factor of 1.4, and the rate was further adjusted if certain financial goals were achieved. In the fourth quarter of 2020, the Company terminated the Anixter Deferred Compensation Plan. Accordingly, the deferred compensation liability of $45.1 million was classified in other current liabilities in the Condensed Consolidated Balance Sheet at December 31, 2020. In the second quarter of 2021, the Company settled the liability for the Anixter Deferred Compensation Plan by making lump sum payments of $42.8 million directly to participants.

The Company held assets in a Rabbi Trust arrangement to provide for the liability associated with the Anixter Deferred Compensation Plan. The assets were invested in marketable securities. As of December 31, 2020, the assets held in this arrangement were $39.6 million and were recorded in other current assets in the Condensed Consolidated Balance Sheets. In the second quarter of 2021, the Company liquidated this investment arrangement for approximately $39.7 million and used the proceeds to fund the settlement of the Anixter Deferred Compensation Plan described above.

Defined Benefit Plans

WESCO sponsors a contributory defined benefit plan (the "EECOL Plan") covering substantially all Canadian employees of EECOL Electric Corp. and a Supplemental Executive Retirement Plan for certain executives of EECOL Electric Corp. (the "EECOL SERP").

Anixter Inc. sponsors defined benefit pension plans in the U.S., which consist of the Anixter Inc. Pension Plan, the Executive Benefit Plan and the Supplemental Executive Retirement Plan (the "Anixter SERP") (together, the "Domestic Plans") and various defined benefit pension plans covering employees of foreign subsidiaries in Canada and Europe (together with the "EECOL Plan" and "EECOL SERP", the "Foreign Plans"). The Anixter Inc. Pension Plan was frozen to entrants first hired or rehired on or after July 1, 2015. The majority of the Anixter defined benefit pension plans are non-contributory, and with the exception of U.S. and Canada, cover substantially all full-time employees in their respective countries. Retirement benefits are provided based on compensation as defined in each of the pension plans.

In the fourth quarter of 2020, the Company terminated both the Anixter Inc. Executive Benefit Plan and the Anixter SERP. Accordingly, pension liabilities totaling $18.1 million associated with the Anixter Inc. Executive Benefit Plan and the Anixter SERP were classified as current in the Condensed Consolidated Balance Sheet at December 31, 2020. In the second quarter of 2021, the Company settled its liability for the Anixter Inc. Executive Benefit Plan by making lump sum payments of $10.4 million directly to participants. The Company expects to make lump sum payments directly to participants of the Anixter SERP during the second half of 2021.

The Domestic Plans are funded as required by the Employee Retirement Income Security Act of 1974 ("ERISA") and the Internal Revenue Service and the Foreign Plans are funded as required by applicable foreign laws. The EECOL SERP and the Anixter SERP are unfunded plans.

The Company made aggregate cash contributions to its Foreign Plans of $3.1 million and $0.8 million during the three months ended June 30, 2021 and 2020, respectively, and $5.7 million and $1.8 million during the six months ended June 30, 2021 and 2020, respectively.

(1)    The Company assumed the Domestic Plans and certain foreign plans, as described above, in connection with the acquisition of Anixter on June 22, 2020. The Company began recognizing the net periodic pension (benefit) cost associated with these plans as of the acquisition date.

(2)    For the three and six months ended June 30, 2021 and 2020, no amounts were reclassified from accumulated other comprehensive income into net income, respectively.

The service cost of $4.1 million and $1.7 million for the three months ended June 30, 2021 and 2020, respectively, and $8.1 million and $3.0 million for the six months ended June 30, 2021 and 2020, respectively, is reported as a component of selling, general and administrative expenses. The other components of net periodic pension (benefit) cost totaling net benefits of $4.2 million and $0.7 million for the three months ended June 30, 2021 and 2020, respectively, and net benefits of $8.2 million and $1.2 million for the six months ended June 30, 2021 and 2020, respectively, are presented as a component of other non-operating income ("other income, net").

Other Benefits

As permitted by the Merger Agreement, Anixter granted restricted stock units prior to June 22, 2020 in the ordinary course of business to its employees and directors. These awards, which did not accelerate solely as a result of the Merger, were converted into cash-only settled WESCO phantom stock units, which vest ratably over a 3-year period. As of June 30, 2021 and December 31, 2020, the estimated fair value of these awards was $18.2 million and $22.8 million, respectively. The Company recognized compensation expense associated with these awards of $0.6 million and $0.9 million for the three months ended June 30, 2021 and 2020, respectively, and $6.3 million and $0.9 million for the six months ended June 30, 2021 and 2020, respectively, which is reported as a component of selling, general and administrative expenses.

STOCK-BASED COMPENSATION

WESCO sponsors a stock-based compensation plan. On May 27, 2021, the Company's stockholders approved the WESCO International, Inc. 2021 Omnibus Incentive Plan (the “2021 Plan”). The 2021 Plan is administered by the Compensation Committee of the Company's Board of Directors.

The 2021 Plan was designed to be the successor plan to all prior stock-based compensation plans. Accordingly, no new awards may be granted under the Company’s 1999 Long-Term Incentive Plan, as amended and restated (the “1999 Plan”) or any other prior plan. Awards outstanding under any such prior plans will remain in full force and effect under such plans according to their respective terms. To the extent that any such award is forfeited, terminates, expires or lapses without being exercised, or is settled for cash, the shares subject to such award not delivered will again be available for awards under the 2021 Plan.

The maximum number of shares of the Company’s common stock that may be granted pursuant to awards under the 2021 Plan is 2,150,000, less any shares issued under the 1999 Plan after March 31, 2021 and until the annual stockholders meeting in May 2021. If any award granted under the 2021 Plan is forfeited, terminates, expires or lapses instead of being exercised, or is settled for cash, the shares subject to such award will again be available for grant under the 2021 Plan. Shares delivered by participants or withheld by the Company to pay all or a portion of the exercise price or withholding taxes with respect to stock option or stock appreciation right awards will not again be available for issuance. Shares delivered by participants or withheld by the Company to satisfy applicable tax withholding obligations with respect to a full-value award (i.e., restricted shares or restricted stock units) will again be available for grant under the 2021 Plan.

WESCO’s stock-based employee compensation awards outstanding under the 1999 Plan are comprised of stock-settled stock appreciation rights, restricted stock units and performance-based awards. Compensation cost for all stock-based awards is measured at fair value on the date of grant and compensation cost is recognized, net of estimated forfeitures, over the service period for awards expected to vest. The fair value of stock-settled stock appreciation rights is determined using the Black-Scholes model. The fair value of restricted stock units and performance-based awards with performance conditions is determined by the grant-date closing price of WESCO’s common stock. The forfeiture assumption is based on WESCO’s historical employee behavior that is reviewed on an annual basis. No dividends are assumed. For stock-settled stock appreciation rights that are exercised and for restricted stock units and performance-based awards that vest, shares are issued out of WESCO's outstanding common stock.

Stock-settled stock appreciation rights vest ratably over a three-year period and terminate on the tenth anniversary of the grant date unless terminated sooner under certain conditions. Restricted stock unit awards granted in February 2020 and prior vest based on a minimum time period of three years. The special award described below vests in tranches. Restricted stock units awarded in 2021 vest ratably over a three-year period on each of the first, second and third anniversaries of the grant date. Vesting of performance-based awards is based on a three-year performance period, and the number of shares earned, if any, depends on the attainment of certain performance levels. Outstanding awards would vest upon the consummation of a change in control transaction and performance-based awards would vest at the target level.

On July 2, 2020, a special award of restricted stock units was granted to certain officers of the Company. These awards vest in tranches of 30% on each of the first and second anniversaries of the grant date and 40% on the third anniversary of the grant date, subject, in each case, to continued employment through the applicable anniversary date.

Performance-based awards granted in 2021, 2020 and 2019 were based on two equally-weighted performance measures: the three-year average growth rate of WESCO's net income and the three-year cumulative return on net assets.

During the three and six months ended June 30, 2021 and 2020, WESCO granted the following stock-settled stock appreciation rights, restricted stock units and performance-based awards at the following weighted-average fair values:

	Three Months Ended				Six Months Ended
	June 30, 2021		June 30, 2020		June 30, 2021		June 30, 2020
Stock-settled stock appreciation rights granted	3,398		—		139,592		262,091
Weighted-average fair value	$	38.62	$	—	$	33.19	$	13.86
Restricted stock units granted	6,861		—		307,583		211,450
Weighted-average fair value	$	86.91	$	—	$	77.12	$	48.32
Performance-based awards granted	3,020		—		122,812		158,756
Weighted-average fair value	$	86.91	$	—	$	76.76	$	48.67

The fair value of stock-settled stock appreciation rights was estimated using the following weighted-average assumptions:

	Three Months Ended			Six Months Ended
	June 30, 2021		June 30, 2020	June 30, 2021		June 30, 2020
Risk free interest rate	1.3	%	n/a	0.8	%	1.4	%
Expected life (in years)	7		n/a	7		5
Expected volatility	42	%	n/a	41	%	30	%

The risk-free interest rate is based on the U.S. Treasury Daily Yield Curve as of the grant date. The expected life is based on historical exercise experience and the expected volatility is based on the volatility of the Company's daily stock price over the expected life preceding the grant date of the award.

The following table sets forth a summary of stock-settled stock appreciation rights and related information for the six months ended June 30, 2021:

	Awards	Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (In years)	Aggregate Intrinsic Value (In thousands)
Outstanding at December 31, 2020	2,161,556	$	60.48
Granted	139,592	77.05
Exercised	(558,550)	54.65
Forfeited	(12,719)	52.57
Outstanding at June 30, 2021	1,729,879	63.76		5.9	$	69,154
Exercisable at June 30, 2021	1,359,501	$	64.73	5.1	$	53,041

For the six months ended June 30, 2021, the aggregate intrinsic value of stock-settled stock appreciation rights exercised during such period was $24.9 million.

The following table sets forth a summary of time-based restricted stock units and related information for the six months ended June 30, 2021:

	Awards	Weighted- Average Fair Value
Unvested at December 31, 2020	921,495	$	43.15
Granted	307,583	77.12
Vested	(226,943)	43.89
Forfeited	(25,134)	59.90
Unvested at June 30, 2021	977,001	$	53.23

The following table sets forth a summary of performance-based awards for the six months ended June 30, 2021:

	Awards	Weighted- Average Fair Value
Unvested at December 31, 2020	305,269	$	52.61
Granted	122,812	76.76
Vested	(22,371)	62.34
Forfeited	(27,802)	59.87
Unvested at June 30, 2021	377,908	$	59.35

Vesting of the 377,908 shares of performance-based awards in the table above is dependent upon the achievement of certain performance targets, including half that are dependent upon the three-year average growth rate of WESCO's net income and the other half that are based upon the three-year cumulative return on net assets. These awards are accounted for as awards with performance conditions; compensation cost is recognized over the performance period based upon WESCO's determination of whether it is probable that the performance targets will be achieved.

WESCO recognized $7.2 million and $4.9 million of non-cash stock-based compensation expense, which is included in selling, general and administrative expenses, for the three months ended June 30, 2021 and 2020, respectively. WESCO recognized $13.2 million and $9.5 million of non-cash stock-based compensation expense, which is included in selling, general and administrative expenses, for the six months ended June 30, 2021 and 2020, respectively. As of June 30, 2021, there was $55.3 million of total unrecognized compensation expense related to non-vested stock-based compensation arrangements for all awards previously made of which approximately $14.8 million is expected to be recognized over the remainder of 2021, $23.9 million in 2022, $15.2 million in 2023 and $1.4 million in 2024.

FAIR VALUE (Notes)

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

10. FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company’s financial instruments primarily consist of cash and cash equivalents, accounts receivable, accounts payable, bank overdrafts, outstanding indebtedness, foreign currency forward contracts, and benefit plan assets. Except for benefit plan assets, outstanding indebtedness and foreign currency forward contracts, the carrying value of the Company’s remaining financial instruments approximates fair value.

The assets of the Company's various defined benefit plans are primarily comprised of common/collective/pool funds (i.e., mutual funds). These funds are valued at the net asset value (NAV) of shares held in the underlying funds. Investments for which fair value is measured using the NAV per share practical expedient are not classified in the fair value hierarchy.

The Company uses a market approach to determine the fair value of its debt instruments, utilizing quoted prices in active markets, interest rates and other relevant information generated by market transactions involving similar instruments. Therefore, the inputs used to measure the fair value of the Company's debt instruments are classified as Level 2 within the fair value hierarchy.

The carrying value of WESCO's debt instruments with fixed interest rates was $3,230.4 million and $3,730.1 million as of June 30, 2021 and December 31, 2020, respectively. The estimated fair value of this debt was $3,520.2 million and $4,084.7 million as of June 30, 2021 and December 31, 2020, respectively. The reported carrying values of WESCO's other debt instruments, including those with variable interest rates, approximated their fair values as of June 30, 2021 and December 31, 2020.

The Company purchases foreign currency forward contracts to minimize the effect of fluctuating foreign currency-denominated accounts on its earnings. The foreign currency forward contracts are not designated as hedges for accounting purposes. The Company's strategy is to negotiate terms for its derivatives and other financial instruments to be highly effective, such that the change in the value of the derivative offsets the impact of the underlying hedge. Its counterparties to foreign currency forward contracts have investment-grade credit ratings. The Company regularly monitors the creditworthiness of its counterparties to ensure no issues exist that could affect the value of its derivatives.

The Company does not hedge 100% of its foreign currency-denominated accounts. In addition, the results of hedging can vary significantly based on various factors, such as the timing of executing foreign currency forward contracts versus the movement of currencies as well as the fluctuations in the account balances throughout each reporting period. The fair value of foreign currency forward contracts is based on the difference between the contract rate and the current exchange rate. The fair value of foreign currency forward contracts is measured using observable market information. These inputs would be considered Level 2 in the fair value hierarchy. At June 30, 2021, foreign currency forward contracts were revalued at then-current foreign exchange rates with the changes in valuation reflected directly in other non-operating expenses ("other income, net") in the Condensed Consolidated Statements of Income and Comprehensive Income (Loss) offsetting the transaction gain (loss) recorded on foreign currency-denominated accounts. At June 30, 2021 and December 31, 2020, the gross and net notional amounts of foreign currency forward contracts outstanding were approximately $215.2 million and $111.9 million, respectively. While all of the Company's foreign currency forward contracts are subject to master netting arrangements with its counterparties, assets and liabilities related to these contracts are presented on a gross basis within the Condensed Consolidated Balance Sheets. The gross fair value of assets and liabilities related to foreign currency forward contracts were immaterial.

COMMITMENTS AND CONTINGENCIES	From time to time, a number of lawsuits and claims have been or may be asserted against the Company relating to the conduct of its business, including litigation relating to commercial, product and employment matters. The outcome of any litigation cannot be predicted with certainty, and some lawsuits may be determined adversely to WESCO. However, management does not believe that the ultimate outcome of any such pending matters is likely to have a material adverse effect on WESCO's financial condition or liquidity, although the resolution in any fiscal period of one or more of these matters may have a material adverse effect on WESCO's results of operations for that period.

INCOME TAXES	6 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	The effective tax rate for the three and six months ended June 30, 2021 was 21.6% and 18.1%, respectively. The effective tax rate for the three and six months ended June 30, 2020 was 24.0% and 67.3%, respectively. WESCO’s effective tax rate typically differs from the federal statutory income tax rate due to the tax effect of intercompany financing, foreign tax rate differences, the U.S. taxes imposed on foreign income, nondeductible expenses and state income taxes. The effective tax rate for the three months ended June 30, 2021 is lower than the corresponding quarter of the prior year primarily due to a discrete income tax benefit of $3.4 million associated with the exercise and vesting of stock-based awards. For the six months ended June 30, 2021, the effective tax rate is lower than the corresponding year-to-date period of the preceding year primarily due to the discrete income tax benefits of $8.3 million resulting from a change in the valuation allowance recorded against foreign tax credit carryforwards, and $4.5 million associated with the exercise and vesting of stock-based awards. In addition, the effective tax rates for the prior year periods were higher due to costs incurred to complete the acquisition of Anixter. There have been no material adjustments to liabilities for uncertain tax positions since the last annual disclosure for the year ended December 31, 2020.

Segment Reporting [Abstract]

Segment Reporting Disclosure

13. BUSINESS SEGMENTS

The Company has operating segments that are organized around three strategic business units consisting of EES, CSS and UBS. These operating segments are equivalent to the Company's reportable segments. The Company's CODM evaluates the performance of its operating segments based primarily on net sales, income from operations, and total assets.

Corporate expenses are incurred to obtain and coordinate financing, tax, information technology, legal and other related services. The Company also has various corporate assets which are reported in corporate. Segment assets may not include jointly used assets, but segment results include depreciation expense or other allocations related to those assets. Interest expense and other non-operating items are not allocated to the segments or reviewed on a segment basis. Corporate expenses are shown in the tables below to reconcile the reportable segments to the consolidated financial statements.

The following tables set forth financial information by reportable segment for the periods presented:

14. SUBSEQUENT EVENTS

On July 2, 2021 (the “Redemption Date”), WESCO Distribution, Inc. redeemed the $350 million aggregate principal amount of its 2024 Notes at a redemption price equal to 101.344% of the principal amount plus accrued interest to, but not including, the Redemption Date. The redemption of the 2024 Notes was funded with borrowings under the Company's accounts receivable securitization and revolving credit facilities.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements of WESCO have been prepared in accordance with Rule 10-01 of Regulation S-X of the Securities and Exchange Commission (the “SEC”). The unaudited condensed consolidated financial information should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in WESCO’s 2020 Annual Report on Form 10-K as filed with the SEC on March 1, 2021. The Condensed Consolidated Balance Sheet at December 31, 2020 was derived from the audited Consolidated Financial Statements as of that date, but does not include all of the disclosures required by accounting principles generally accepted in the United States of America.

The unaudited Condensed Consolidated Balance Sheet as of June 30, 2021, the unaudited Condensed Consolidated Statements of Income (Loss) and Comprehensive Income (Loss), the unaudited Condensed Consolidated Statements of Stockholders' Equity for the three and six months ended June 30, 2021 and 2020, and the unaudited Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2021 and 2020, respectively, in the opinion of management, have been prepared on the same basis as the audited Consolidated Financial Statements and include all adjustments necessary for the fair statement of the results of the interim periods presented herein. All adjustments reflected in the unaudited condensed consolidated financial information are of a normal recurring nature unless indicated. The results for the interim periods presented herein are not necessarily indicative of the results to be expected for the full year.

Prior to the completion of its merger with Anixter International Inc. ("Anixter") on June 22, 2020, as described in Note 4, "Acquisitions and Disposals", WESCO had four operating segments that had been aggregated as one reportable segment. Effective on the date of acquisition, the Company added Anixter as a separate reportable segment for the quarterly period ended June 30, 2020. At the beginning of the third quarter of 2020, the Company identified new operating segments organized around three strategic business units consisting of EES, CSS and UBS. These operating segments are equivalent to the Company's reportable segments. The operating segments in the respective periods were determined in accordance with the manner in which WESCO's chief operating decision maker ("CODM") reviewed financial information during those periods. The financial information used by the CODM to evaluate the performance of the Company's operating segments is disclosed in Note 13, "Business Segments". The applicable comparative financial information reported in the Company's previously issued interim financial statements for the three and six months ended June 30, 2020 has been recast in this Quarterly Report on Form 10-Q to conform to the basis of the new segments.

Reclassifications [Text Block]

Reclassifications

For the three and six months ended June 30, 2020, $0.7 million and $0.8 million, respectively, of other non-operating income has been reclassified from "net interest and other" to "other income, net" in the unaudited Condensed Consolidated Statements of Loss and Comprehensive Loss. For the six months ended June 30, 2020, stock-based compensation of $9.5 million and amortization of debt discount and debt issuance costs of $2.1 million have been reclassified from other operating activities in the unaudited Condensed Consolidated Statement of Cash Flows. These reclassifications have been made to conform to the current period presentation.

Change in Estimates

During the second quarter of 2021, the Company established a new corporate brand strategy that will result in migrating certain legacy WESCO sub-brands to a master brand architecture. The Company accounts for the trademarks associated with these sub-brands as intangible assets. As of December 31, 2020, $39.1 million of the trademarks impacted by the master brand strategy had indefinite lives and $9.5 million had remaining estimated useful lives ranging from 3 to 8 years. The Company continually evaluates whether events or circumstances have occurred that would require a change to the estimated useful lives of indefinite-lived and definite lived intangible assets. When such a change is warranted, the remaining carrying amount of the intangible asset is amortized prospectively over the revised remaining useful life. Accordingly, during the second quarter of 2021, the Company changed the estimated useful lives of the trademarks affected by the new corporate brand strategy to coincide with the expected period of time to migrate such sub-brands to the master brand architecture. The Company assigned remaining estimated useful lives to these trademarks, including those that previously had indefinite lives, ranging from less than one year to 5 years. The Company assessed these intangible assets for impairment prior to amortizing them over their revised estimated remaining useful lives. No impairment losses were identified as a result of these tests.

New Accounting Pronouncements and Changes in Accounting Principles [Text Block]

Recently Adopted Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which removes certain exceptions to the general principles of Accounting Standards Codification Topic 740, Income Taxes, and simplifies other aspects of accounting for income taxes. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted in any interim or annual period, with any adjustments reflected as of the beginning of the fiscal year of adoption. The Company adopted this ASU in the first quarter of 2021. The adoption of this guidance did not have a material impact on the consolidated financial statements and notes thereto presented herein.

New Accounting Pronouncements, Policy

Recently Issued Accounting Pronouncements

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this Update are effective for all entities as of March 12, 2020 through December 31, 2022. Management is currently evaluating the impact related to the replacement of London Interbank Offered Rate (LIBOR) and whether the Company will elect the adoption of the optional guidance.

Other pronouncements issued by the FASB or other authoritative accounting standards groups with future effective dates are either not applicable or are not expected to be significant to WESCO’s financial position, results of operations or cash flows.
