Note:
Totals may not equal sum of components because of independent rounding.
Heat and sulfur content categories of coal resources and reserves
are rounded to one decimal place. Conversion of heat and sulfur contents
to millions of Btu per short ton and pounds of sulfur per million
Btu, respectively, produces values with multiple decimal places. These
are rounded to one place within category allocations, as an appropriate
expression of accuracy for estimates extended to in-place coal resources
and reserves.
