FCB, 13G's are required to be filed when an entity becomes a 5% ownership holder, or changes amount after already being a 5% holder. 13G's must be filed by 45 days after the end of the quarter in which the ownership change occurred, hence the deadline is Feb 15 for any 5% holder changes from Q4.
In this case, as of Nov 2013, Dennis Mehiel owns (owned) 1.8m shares and 1.4m warrants, for 3.2m total. Not sure if this is an increase or decrease from his previous (he was already a 5% holder).
