      Note: At the time of this writing, the end port in Chinese Taipai was        
      still under evaluation. Keelung has been requested as the end port        
      for PR purposes. This is currently under review. This time estimate        
      and operating plan assumes Keelung as the end port, however        
      the initial port, Kao-hsuing is also shown for information only.
