Award Timing MNPI Disclosure	The Compensation & HR Committee generally evaluates and approves annual equity grants at or about the same time as it determines and approves annual salary adjustments and annual incentive payouts. Annual equity grants typically are made in late February or early March at a special meeting of the Compensation & HR Committee (for the NEOs other than the CEO) and a special meeting of the Board (in the case of the CEO). Individual recognition equity awards may be granted at other times during the year, typically on the first trading day of a month, related to special circumstances, such as acquisitions, establishment of joint ventures, promotions, extraordinary performance, retention and other events.
