dividend equivalent rights financial

"Represents dividend equivalent rights ("DERs") in connection with the Issuer's quarterly dividend"

Dividend equivalent rights are promises that mirror the cash payments shareholders get from a company’s profits, but they are paid to holders of certain awards (like stock options or restricted stock units) rather than to actual shares. Think of them as a paycheck top‑up that matches dividends while the award is not yet a real stock, and they matter to investors because they add to employee compensation costs and potential share dilution, affecting company profitability and per‑share value.

restricted stock units financial

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

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

deferred share units financial

"Represents deferred share units ("DSUs") credited to the Reporting Person's deferred compensation account"

Deferred share units are promises that give an executive or director the right to receive company shares or their cash value at a future date, often when they retire or leave the company. Think of them as a paycheck held in a savings account that converts into stock later; they matter to investors because they tie pay to long-term performance, create potential future dilution of shares, and represent a delayed cash or share obligation the company must eventually fulfill.

Deferred Compensation Plan for Non-Employee Directors financial

"credited to the Reporting Person's deferred compensation account pursuant to the Issuer's Deferred Compensation Plan for Non-Employee Directors"

FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What did WESCO (WCC) director Easwaran Sundaram report in this Form 4?

He reported two equity compensation awards in WESCO common stock, not open-market trades. The filing shows additional shares credited through dividend equivalent rights and deferred share units, increasing his direct holdings to about 14,660 shares of WESCO International common stock.

How many WESCO shares were granted to director Easwaran Sundaram?

He was credited with 90.467 shares of WESCO common stock as dividend equivalent rights and 21.0587 deferred share units. Together, these awards modestly increase his equity exposure as part of director compensation rather than reflecting a large, discretionary market purchase or sale.

Were these WESCO (WCC) transactions open-market buys or sells?

No, they were coded as acquisitions under transaction code A, indicating grants or awards. The 90.467 shares and 21.0587 deferred share units arose from compensation arrangements, so no open-market buying or selling activity by the director is reported in this Form 4.

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

Dividend equivalent rights mirror WESCO’s quarterly dividend on existing restricted stock units. Each DER equals one share of common stock and vests on the same schedule as the underlying RSU award, giving the director stock-based value instead of immediate cash dividends on unvested units.

What are deferred share units (DSUs) reported for WESCO director Sundaram?

Deferred share units are bookkeeping entries in the director’s deferred compensation account. Each DSU is economically equivalent to one WESCO common share and can later be distributed in stock, following a schedule the director elected under the company’s Deferred Compensation Plan for Non-Employee Directors.

How many WESCO shares does Easwaran Sundaram hold after these awards?

After the larger award, the filing shows total direct holdings of 14,660.171 WESCO common shares. This figure reflects his position following the credited dividend equivalent rights and is a context number indicating his ongoing equity stake as a non-employee director.
