"accrued to the Reporting Person on restricted stock units ("RSUs") held by the Reporting Person"

Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

FAQ

What did WESCO (WCC) director James Louis Singleton report on this Form 4?

James Louis Singleton reported receiving 35.2215 dividend equivalent rights, economically equal to WESCO common shares. These arose from the company’s quarterly dividend and accrued on restricted stock units he already holds, increasing his directly held share-equivalent position.

Are the reported WESCO (WCC) Form 4 transactions a market purchase or sale?

The Form 4 shows no market purchase or sale. Singleton received a grant of dividend equivalent rights as compensation linked to existing restricted stock units, so this is a non-cash, stock-based award rather than an open-market trade in WESCO shares.

How many WESCO (WCC) share equivalents does James Louis Singleton hold after this filing?

After this award, James Louis Singleton directly holds 39,644.8209 WESCO common stock or equivalent units. This total includes the newly accrued 35.2215 dividend equivalent rights tied to his restricted stock units, reflecting his updated equity-based position in the company.

What are dividend equivalent rights (DERs) in the WESCO (WCC) Form 4 filing?

Dividend equivalent rights are instruments that mirror dividends on underlying awards. In this case each DER is economically equal to one WESCO common share and accrues on restricted stock units, vesting on the same schedule as the related RSU grant held by the director.

Do the WESCO (WCC) dividend equivalent rights vest immediately for James Louis Singleton?

The dividend equivalent rights do not vest immediately. They vest on the same schedule as the underlying restricted stock units on which they accrued, meaning their vesting depends entirely on the vesting timetable and conditions of the related RSU awards already granted.
