RESTRICTED CASH
NOTE 4 — RESTRICTED CASH
On May 21, 2009, we entered into a cash collateral agreement with our agent bank to obtain letters of credit secured by cash collateral. The restricted cash is invested in a cash bank account securing our agent bank. As of July 31, 2011 and October 31, 2010, we had restricted cash in the amount of $2.8 million as collateral related to our $2.7 million of letters of credit. Restricted cash is classified as a current asset as the underlying letters of credit expire by October 2011. The letters of credit have either automatically renewed or will be renewed upon expiration.
