Net loss attributable to common shareholders in the 2015 fiscal fourth quarter totaled ($1.7) billion, or ($17.92) per diluted share, compared with fiscal 2014 fourth-quarter net loss attributable to common shareholders of ($18.3) million, or ($0.24) per diluted share.

Fiscal 2015 net loss attributable to common shareholders was ($2.4) billion, or ($25.97) per diluted share, on revenues of $1.4 billion and production of 58,900 BOE/d.

Results for the fiscal fourth-quarter and fiscal year-end 2015 were significantly impacted by non-cash ceiling test write-downs of oil and gas properties, driven by lower commodity prices.
