Are you aware that March 31, 2014 is 3 months after Dec 31, 2013?
So.
On March 31, 2014 there were 1.17B in the float.
Three months before that, on Dec 31, 2013, there were 1.2B in the float.
That means that the company must have bought back 24 million shares between Dec 31, 2013 and March 31, 2014.
The share structure in the link you've provided is outdated, by 3 months. The updated share structure can be found in the 2014 Q1 Quarterly report posted on OTCMarkets.com on May 19, 2014. The link to said report is hyperlinked twice in the post you replied to.
