Our reserves are geographically diverse and cover a broad range of heat and sulfur content. By offering both metallurgical and steam coal, our coal reserves are marketable to a diverse customer base, thereby enabling our lessees to adjust to changing markets and sustain sales volumes and prices. By having reserves in different geographic areas with various types of coal reserves, our lessees are able to serve a broad number of markets and take advantage of changing customer preferences.

Due to the number of mineral areas involved in the BRP transaction, we have not completed an analysis of the reserve quantity and quality for each mineral that was acquired.  As a result, the reserves held by BRP are not included in the statistical information. We plan to complete a review of the BRP reserves by the end of 2011.
