Production

In 2012, Walter Energy produced 11.7 million metric tons (MMTs) of met coal, up 34% percent from 8.7 million MMTs of met coal produced in 2011. In the fourth quarter of 2012, Walter Energy produced 2.5 MMTs of met coal which reflected implementation of a reduced operating schedule in response to lower global demand and pricing.

Sales Volume and Price

In 2012, Walter Energy sold 10.4 MMTs of met coal, up 20% from 8.7 MMTs of met coal sales in 2011. Fourth quarter 2012 met coal sales volume totaled 2.5 MMTs. However, approximately 200,000 metric tons of contracted shipments were delayed into 2013 due to issues with rail and port availability and are not included in 2012 sales. Reflecting current trends in global coal markets, Walter Energy’s met coal prices for the fourth quarter of 2012 averaged approximately $152 per metric ton (MT) for hard coking coal as compared with $198 per MT in the third quarter of 2012. The fourth quarter prices for low-vol PCI averaged approximately $129 per MT as compared with $160 per MT in the third quarter of 2012.
