restricted stock units financial

"Grant of restricted stock units under the Issuer's 2022 Long-Term Incentive Plan."

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.

2022 Long-Term Incentive Plan financial

"Grant of restricted stock units under the Issuer's 2022 Long-Term Incentive Plan."

Rabbi Trust financial

"Does not include 977 shares held indirectly in a Rabbi Trust pursuant to deferral agreements."

A rabbi trust is a special account a company sets up to hold promised future pay for executives, like bonus or retirement money, so those employees can see there are funds earmarked for them. It matters to investors because it signals the company’s commitment to keep key people, but the money is still part of the company’s assets and can be claimed by creditors if the company goes bankrupt—think of it as a labeled jar that isn’t completely off-limits.

deferral agreements financial

"Does not include 977 shares held indirectly in a Rabbi Trust pursuant to deferral agreements."
