Purchase Obligations
 
The following items are the only material changes to long-term purchase commitments during the nine months ended September 30, 2011:

In 2011, Idaho Power entered into several power purchase agreements with wind and other alternative energy developers.  Payments pursuant to these agreements are expected to total approximately $128 million from 2011 to 2037.
The IPUC issued orders on June 8, 2011 that disapproved 13 wind power purchase agreements. The orders were subject to a 21-day reconsideration period and reconsiderations were denied by the IPUC on July 27, 2011. At this time, Idaho Power considers all of these agreements to be terminated, though two of the projects have filed appeals with the Idaho Supreme Court. Payments pursuant to these 13 agreements were expected to total approximately $1.3 billion over the terms of the agreements and had previously been reported as purchase obligations.

Guarantees
 
Idaho Power has agreed to guarantee a portion of the performance of reclamation activities and obligations at BCC, of which IERCo owns a one-third interest.  This guarantee, which is renewed each December, was $63 million at September 30, 2011, representing IERCo's one-third share of BCC's total reclamation obligation of $189 million.  BCC has a reclamation trust fund set aside specifically for the purpose of paying these reclamation costs.  At September 30, 2011, the value of the reclamation trust fund totaled $74 million. BCC periodically assesses the adequacy of the reclamation trust fund and its estimate of future reclamation costs.  To ensure that the reclamation trust fund maintains adequate reserves, BCC has the ability to add a per-ton surcharge to coal sales.  Starting in 2010, BCC began applying a nominal surcharge to coal sales in order to maintain adequate reserves in the reclamation trust fund.  Because of the existence of the fund and the ability to apply a per-ton surcharge, the estimated fair value of this guarantee is minimal.
 
IDACORP and Idaho Power enter into financial agreements and power purchase and sale agreements that include indemnification provisions relating to various forms of claims or liabilities that may arise from the transactions contemplated by these agreements.  Generally, a maximum obligation is not explicitly stated in the indemnification provisions and, therefore, the overall maximum amount of the obligation under such indemnification provisions cannot be reasonably estimated.  IDACORP and Idaho Power periodically evaluate the likelihood of incurring costs under such indemnities based on their historical experience and the evaluation of the specific indemnities.  As of September 30, 2011, management believes the likelihood is remote that IDACORP or Idaho Power would be required to perform under such indemnification provisions or otherwise incur any significant losses with respect to such indemnification obligations.  Neither IDACORP nor Idaho Power has recorded any liability on their respective condensed consolidated balance sheets with respect to these indemnification obligations.
