Footnote F1

The dividend equivalent rights were converted into, and paid in the form of, shares of the Issuer's common stock on a one-for-one basis in connection with the vesting of restricted stock units to which the dividend equivalent rights relate. A cash amount was also paid to the holder to settle a fractional dividend equivalent right.

Footnote F2

Payment of tax obligation by withholding securities incident to the vesting of securities in accordance with Rule 16b-3(e).
