Effective Time technical

"At the effective time of the Merger"

The exact clock time when a regulatory filing, approval, or corporate action formally becomes legally active; from that moment the change is binding and can be acted on. Investors care because the effective time marks when ownership, rights, trading rules, or new securities take effect — like a light switch turning on a contract or transaction — which determines when risks, benefits and market reactions begin.

Company RSU financial

"an award of restricted stock units of the Issuer"

Company PSU financial

"each award of performance stock units of the Issuer"

Per Share Price financial

"equal to $9.50, without interest thereon"
