vested". In cases of partial vesting, a "vesting schedule" is a table or chart showing the portion of a right that is vested over time; typically the schedule provides for equal portions to vest on periodic vesting dates, usually once per day, month, quarter, or year, in stairstep fashion over the course of the vesting period. Often there is a cliff by which the first few steps in the graph are missing, so that there is no vesting at all for a period (usually six or twelve months in the case of employee equity), after which there is a cliff date upon which a large amount of vesting occurs all at once. Some arrangements provide for "accelerated vesting", by which all or a major portion of the unvested right vests all at once upon the occurrence of a specified event such as a termination of employment by the company or acquisition of the company by another. Less commonly, the vesting schedule may call for variable grants or subject to conditions such as reaching milestones or employee performance. "Graded vesting" or called retable vesting (vesting after each year until the employee is fully vested) may be "uniform" (e.g., 20% of the compensation vested each year for five years) or "non-uniform" (e.g., 20%, 30%, and 50% of the compensation vested each year for the next three years).
