Vesting of Performance Share Units under 2004 Share Compensation Plan
On September 13, 2010, the Compensation Committee of the Board of Directors (the "Committee") granted performance-vesting restricted share units ("PSUs") to certain of the Company's executive officers, including the named executive officers listed in the table below, under the terms of the Company's 2004 Share Compensation Plan. The PSUs were eligible to vest after the end of a three-year performance period, subject to continued employment and the achievement of average annual return on invested capital ("ROIC") over the performance period, modified by a factor based on the Company's relative total shareholder return ("TSR") percentile compared with a selected peer group, as generally described under the heading "Compensation Discussion and Analysis—Long-Term Equity Incentives— Stock Awards (Restricted Shares, Restricted Share Units, Threshold Performance Shares and Performance Share Units) —Performance Share Units" on pages 45 and 46 of our proxy statement for our fiscal year ended July 1, 2011, filed with the Securities and Exchange Commission on September 21, 2011.
On September 19, 2013, the Committee certified the level of achievement of the financial performance metrics for the three-year performance period ending June 28, 2013. The PSUs will vest at 192.5% of target, on the basis of achievement of average annual ROIC of 63% and relative TSR at the 100th percentile over the performance period.
The actual number of shares to be issued to the named executive officers listed in our 2013 proxy statement pursuant to the PSU vesting is shown in the table below.
