Item 5. Other Information

Our officers (as defined in Rule 16a-1(f) under the Exchange Act) have historically entered into sell-to-cover arrangements pursuant to Rule 10b5-1 authorizing the pre-arranged sale of shares to satisfy our tax withholding obligations arising exclusively from the vesting of time-vesting or performance-vesting restricted stock units and the related issuance of shares. The amount of shares to be sold to satisfy our tax withholding obligations under these arrangements has been dependent on future events which cannot be known in advance, including the future trading price of our shares. The expiration date relating to these arrangements has been dependent on future events which cannot be known in advance, including the final vest date of the applicable time-vesting or performance-vesting restricted stock units and the officer’s termination of service.
