Guarantees [Text Block]	8. Guarantees Arrow does not issue any guarantees that would require liability-recognition or disclosure, other than its standby letters of credit. Standby and other letters of credit are conditional commitments issued by Arrow to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements, including bond financing and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Typically, these instruments have terms of twelve months or less. Some expire unused, and therefore, the total amounts do not necessarily represent future cash requirements. Some have automatic renewal provisions. For letters of credit, the amount of the collateral obtained, if any, is based on management’s credit evaluation of the counter-party. Arrow had approximately $8.3 million of standby letters of credit on June 30, 2011, most of which will expire within one year and some of which were not collateralized. At that date, all standby letters of credit were for private borrowing arrangements. The fair value of Arrow’s standby letters of credit at June 30, 2011 was insignificant.
