The Compensation Committee of the Board of Directors has since "deemed satisfied" those performance conditions. The resulting earned awards vest one-third on the first anniversary of the original grant date, with an additional one-third vesting over each of the following two years, subject to continued employment with the company.

Following the RSU acquisition, the filing records three withholding transactions under transaction code "F," each at $1,018.21 per share.
