Our minimum stock ownership guidelines require each executive officer to maintain a minimum equity investment in our
Company based upon a multiple of their base salary. Pursuant to our guidelines, each executive officer must achieve
the minimum equity investment within five years from the date they first become subject to the guidelines and, until
that time, must retain at least 60% of the after-tax shares of our common stock granted to the executive officer or
purchased by the executive officer through the exercise of stock options. Shares held in a trust or foundation that
are not reported as beneficially owned by the executive, performance awards that have not yet vested and stock
options that have not been exercised are not included when calculating an executive officer's share ownership. Stock
appreciation rights, if granted, and shares subject to floors, collars or other hedging arrangements, if permitted,
also would be excluded from this calculation pursuant to the Company's policy.
