 Other Compensation” because no amounts would have been included in such columns.

DIRECTOR SHARE OWNERSHIP REQUIREMENTS

| ​ | ​ | We believe that our directors should hold a significant amount of Company equity to link their long-term economic interests directly to those of our stockholders. Accordingly, we have established requirements that our directors own at minimum equity of the Company valued at five times their annual retainers. | ​ | ​ |     | ​ |

We believe that this multiple constitutes significant amounts for our directors and provides a substantial link between the interests of our directors and those of our stockholders. During such time that a director has not attained the share ownership guideline, such director is required to retain at least 50% of the shares acquired upon exercise of options or vesting RSU awards, net of amounts required to pay taxes and exercise price. We periodically review our minimum equity ownership guidelines. For purposes of meeting the ownership requirements, unvested RSUs are counted, but unearned performance awards and unexercised stock options are not. Each of our directors meets or exceeds our minimum equity ownership guidelines.
