Okay, I appreciate that.
I have limited time remaining, but in your presentation, you talked about sales in 2014 being $621 billion, up 5.2% for the year, which is very good news. Exports were a record $525 billion. And 2015 is not starting out as positive, but can you give us some sense as to why figures were up that much in 2014? What led to that positive outcome?
