Did you know that they are required to own stock as part of their employment contracts?
Stock Ownership Guidelines. Delta’s stock ownership guidelines strengthen the alignment between executive officers and stockholders. Under these guidelines, which were significantly enhanced in 2013 as explained on page 25 of this proxy statement, the current executive officers are required to own the shares of Delta common stock equal or greater to:
Shares Equal to a Multiple of Base Salary
CEO 8x or 400,000
President 6x or 200,000
Executive Vice Presidents 4x or 150,000
In addition, each executive officer must hold at least 50% of all net shares received through restricted stock vesting or realized through stock option exercises until the stock ownership guidelines applicable to the executive officer are achieved. For these purposes, net shares means all shares retained after applicable withholding of any shares for tax purposes and stock ownership includes shares (including restricted stock) owned directly or held in trust by the executive officer or an immediate family member who resides in the same household. It does not include shares an executive officer has the right to acquire through the exercise of stock options.
