5 terms

short-term incentive plan financial

"year-end target bonus of 75% of her annual base salary under the short-term incentive plan"

long-term incentive grants financial

"the Employment Agreement confirms that Ms. Buczkowski will be eligible for annual long-term incentive grants"

Good Reason regulatory

"terminated without Cause (as defined in the Employment Agreement) or with Good Reason (as defined in the Employment Agreement)"

non-competition regulatory

"non-competition and non-solicitation restrictions (both of employees and business relationships)"

A non-competition is a contractual restriction that prevents a person or business from starting or working in a competing business within a specified time and geographic area after leaving a job or completing a transaction. It matters to investors because it acts like a temporary fence around customers, trade secrets and know‑how, helping protect future revenue and company value; weak or unenforceable restrictions can increase the risk of customer loss and competitive erosion.
