Said report shall be presented to ANH in a term no later than fifteen (15) Calendar Days as of said non-controllable problem start. If ANH accepts that THE CONTRACTOR terminates the drilling operations in the aforementioned well, it should abandon or complete it up to reached depth, and the Minimum or Subsequent Exploratory Plan obligation for such well shall be understood as fulfilled.

Where:

 

Po(n-1):   is the Po value of the immediately preceding Calendar year.
l(n-2):   is the annual variation, expressed in fraction, of the US producer price index for Calendar Year, two years before the one calculated, published by the US Treasury Department

Aforementioned calculation shall be made in December each year.
