Time-based restricted stock units convert into common stock on a one-for-one basis.
The number of common shares beneficially owned were previously reported incorrectly due to a clerical error made by the internal legal administration group which files Section 16 reports on behalf of Company reporting persons.  The correct number of shares was 25,099.041 prior to the current transaction.
Performance-based restricted stock units. Vesting is subject to applicable grant agreement and Compensation and Management Development Committee certification that the Company has met the applicable three year performance measures for certain financial metrics not solely tied to the market price of issuer securities.  The payout will range from 0 percent to 200 percent of the awarded number of units.
