2015 - per the 10K, page-2

Cmon, appreciate the effort you have put in your post and I think a pretty good summary. I had a quick look at the reports and will have a closer look today as I have a different take on some of it but haven't done the work to support yet. The key things I scanned for were the covenants, Top 20 movement and cash cost. Like you I expected impairments and think the low MC also put pressure on this and flows from Oil price as mentioned.
In all some good discussion points for future and at face value I think the report was pretty good considering the oil price drop.
Cheers
