(4) | As of April 30, 2013 and October 31, 2012, the loss reserve on SA's totaled $5.0 million. Also included in this line item is a reserve for performance guarantees penalties under the terms of our customer contracts, which based on our ongoing analysis of historical fleet performance totaled $1.2 million and $2.2 million as of April 30, 2013 and October 31, 2012, respectively. The decrease in the reserve for performance guarantees penalties was due to certain amounts being reclassed to accounts payable due to the finalization of negotiations of amounts due to POSCO.
