"the Company sold a majority of this equipment for $11.2 of which
$4.7 is restricted to pay the January 15, 2010 semi-annual interest on the Notes and
$2.2 million is restricted until the beginning of December 2009"

Interesting that some of the proceeds are reserved for bondholder interest -- that could only have come from a negotiated agreement as there is no security interest in the bond indenture.

Seems that the equipment sold was most likely CAT ("mobile") equipment, which is no longer in significant demand with the economic slowdown. The long lead time stuff is likely in the ~ $37 million mining equipment remaining. Looks like we'll be waiting a while longer for the answers that we need.
