About these balances

Latest available filing per company, not a reconstructed current portfolio. Matching sequences show the last reported balance with all source rows expandable; grouping alone does not establish account ownership. Do not add unresolved positions together. Filings may omit unchanged positions, and amendments may correct only part of an older disclosure. Jointly reported shares are not necessarily this owner's personal holdings.

No balances currently tracked through insider filings.

Past disclosures · reporting ended (1)

No longer tracked through insider filings. These historical balances do not imply present ownership or a zero position.

F2 · shares: Each performance share unit ("PSU") represents the right to receive one share of Common Stock. The PSUs awarded cliff-vest after a 3-year performance period. The Performance Period was the Company's fiscal years 2015, 2016 and 2017. The number of PSUs earned by the Awardee for the Performance Period was determined at the end of the Performance Period by measuring relative total shareholder return ("TSR"), with equal weight given to the selected industry peer group and to the S&P 1000. The TSR peer group performance percentile was 89%, and the TSR S&P 1000 performance percentile was 82%. Straight line interpolation determined the vesting credit percentage. Therefore, 189% of the 3,078 PSUs awarded on November 21, 2014 were earned and vested on November 21, 2017.
