In the Offer to Purchase, under exercise of Kinross Warrants, it states on pg 33:
"Each whole Kinross Warrant....(Toronto time) on the date that is five years following..."

the full text is:

"Each whole Kinross Warrant will entitle the warrantholder to purchase one Kinross Share at an exercise price of Cdn $32.00 as adjusted (the Exercise Price) until 5:00 p.m. (Toronto time) on the date that is five years following the Effective Date."

the operative word left out is "until" so it is any time in the next five years. i don't think even a kinross lawyer could cook up a warrant that could only be exercised on one day in five years.
