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 $16.4 million and $3.5 million for the three months ended September 30, 2021 and 2020, respectively, and $49.1 million and $12.6 million for the nine months ended September 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 September 30, 2021, the Company's obligation under the WESCO Deferred Compensation Plan was $19.9 million, which is 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 closed 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 of $7.5 million directly to participants of the Anixter SERP in the fourth quarter 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 $2.4 million and $2.2 million during the three months ended September 30, 2021 and 2020, respectively, and $8.1 million and $4.0 million during the nine months ended September 30, 2021 and 2020, respectively. The following tables set forth the components of net periodic pension (benefit) cost for the Company's defined benefit plans:

(1) The Company assumed the Domestic Plans and certain of the 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. The service cost of $4.0 million and $3.8 million for the three months ended September 30, 2021 and 2020, respectively, and $12.1 million and $6.8 million for the nine months ended September 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 $4.1 million and $3.6 million for the three months ended September 30, 2021 and 2020, respectively, and net benefits of $12.3 million and $4.8 million for the nine months ended September 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 September 30, 2021 and December 31, 2020, the estimated fair value of these awards was $20.5 million and $22.8 million, respectively. The Company recognized compensation expense associated with these awards of $3.4 million and $1.4 million for the three months ended September 30, 2021 and 2020, respectively, and $9.8 million and $2.3 million for the nine months ended September 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 between March 31, 2021 and May 27, 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 restricted shares or restricted stock units will again be available for grant under the 2021 Plan. Stock-based employee compensation awards outstanding under WESCO's plans 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 are based on two equally-weighted performance measures: the three-year average growth rate of WESCO's net income attributable to common stockholders and the three-year cumulative return on net assets. During the three and nine months ended September 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 |  | Nine Months Ended
| September 30, 2021 |  | September 30, 2020 |  | September 30, 2021 |  | September 30, 2020
Stock-settled stock appreciation rights granted | — |  |  | — |  |  | 139,592 |  |  | 262,091 |
Weighted-average fair value | $ | — |  |  | $ | — |  |  | $ | 33.19 |  |  | $ | 13.86 |
Restricted stock units granted | 6,897 |  |  | 444,375 |  |  | 314,480 |  |  | 655,825 |
Weighted-average fair value | $ | 108.76 |  |  | $ | 32.18 |  |  | $ | 77.81 |  |  | $ | 37.38 |
Performance-based awards granted | — |  |  | — |  |  | 122,812 |  |  | 158,756 |
Weighted-average fair value | $ | — |  |  | $ | — |  |  | $ | 76.76 |  |  | $ | 48.67 |
The fair value of stock-settled stock appreciation rights was estimated using the following weighted-average assumptions:
|  |  | Nine Months Ended
|  |  |  |  | September 30, 2021 |  | September 30, 2020
Risk free interest rate |  |  |  |  | 0.8 | % |  | 1.4 | %
Expected life (in years) |  |  |  |  | 7 |  | 5
Expected volatility |  |  |  |  | 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 nine months ended September 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 | (671,272) |  |  | 55.93 |  |  |  |  |
Forfeited | (12,719) |  |  | 52.57 |  |  |  |  |
Outstanding at September 30, 2021 | 1,617,157 |  |  | 63.87 |  |  | 5.7 |  | $ | 83,206 |
Exercisable at September 30, 2021 | 1,247,342 |  |  | $ | 64.94 |  |  | 4.9 |  | $ | 62,835 |
For the nine months ended September 30, 2021, the aggregate intrinsic value of stock-settled stock appreciation rights exercised during such period was $31.0 million. The following table sets forth a summary of time-based restricted stock units and related information for the nine months ended September 30, 2021:
| Awards |  | Weighted- Average Fair Value
Unvested at December 31, 2020 | 921,495 |  |  | $ | 43.15 |
Granted | 314,480 |  |  | 77.81 |
Vested | (228,584) |  |  | 44.02 |
Forfeited | (30,182) |  |  | 62.68 |
Unvested at September 30, 2021 | 977,209 |  |  | $ | 53.41 |
The following table sets forth a summary of performance-based awards for the nine months ended September 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 September 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 attributable to common stockholders 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 $9.6 million and $6.0 million of non-cash stock-based compensation expense, which is included in selling, general and administrative expenses, for the three months ended September 30, 2021 and 2020, respectively. WESCO recognized $22.8 million and $15.5 million of non-cash stock-based compensation expense, which is included in selling, general and administrative expenses, for the nine months ended September 30, 2021 and 2020, respectively. As of September 30, 2021, there was $53.2 million of total unrecognized compensation expense related to non-vested stock-based compensation arrangements for all awards previously made of which approximately $8.0 million is expected to be recognized over the remainder of 2021, $26.4 million in 2022, $17.0 million in 2023 and $1.8 million in 2024.
Compensation Related Costs, General | 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 September 30, 2021 and December 31, 2020, the estimated fair value of these awards was $20.5 million and $22.8 million, respectively. The Company recognized compensation expense associated with these awards of $3.4 million and $1.4 million for the three months ended September 30, 2021 and 2020, respectively, and $9.8 million and $2.3 million for the nine months ended September 30, 2021 and 2020, respectively, which is reported as a component of selling, general and administrative expenses.

Deferred compensation arrangements may include a description of an arrangement with an individual employee, which is generally an employment contract between the entity and a selected officer or key employee containing a promise by the employer to pay certain amounts at designated future dates, usually including a period after retirement, upon compliance with stipulated requirements. This type of arrangement is distinguished from broader based employee benefit plans as it is usually tailored to the employee. Disclosure also typically includes the amount of related compensation expense recognized during the reporting period, the number of shares (units) issued during the period under such arrangements, and the carrying amount as of the balance sheet date of the related liability. + References Reference 1: http://www.xbrl.org/2003/role/disclosureRef -Publisher FASB -Name Accounting Standards Codification -Topic 710 -URI http://asc.fasb.org/topic&trid=2127225 Reference 2: http://www.xbrl.org/2003/role/disclosureRef -Publisher FASB -Name Accounting Standards Codification -Topic 710 -SubTopic 10 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=6409950&loc=d3e20396-108366 + Details
