US brewer Redhook Ale has reshuffled its top management team.

Redhook CFO and COO David J. Mickelson has also been handed the role of president at the company. Former president and CEO Paul S. Shipman is to continue to serve as chief executive, as well as chairman of the board, the company said yesterday (5 December).

The microbrewer's board has also accelerated the vesting of all of its unvested stock options. As a result, options to acquire roughly 137,000 common shares, or 16% of the total outstanding options, will become exercisable on 30 December.

Redhook said it did not expect the modification to have a material impact on its results for 2005.
