In conjunction with the Presidio Acquisition, certain employees rolled the value of their vested Predecessor stock options into vested Successor stock options. For those employees that did not roll their stock options, the outstanding stock options were canceled in exchange for a cash payment equal to their intrinsic value at the acquisition price.
