Annual Compliance Filing of Asset Retirement Obligations ("ARO") Accounting
Standards Codification ("ASC') 410
Dear Ms. Noriyuki:
ln Order No. 29414, the ldaho Public Utilities Commission directed ldaho Power Company
("Company") to record regulatory assets or liabilities associated with implementation of Statement
of Financial Accounting Standards 143 (now codified as Accounting Standards Codification
("ASC") 410). As a result of the Order, the Company is required to file annually, and as part of
any rate case filing, all journal entries made under the requirements of ASC 410.
On May 17,2012, Order No. 32549was issued authorizing the Companyto begin recovery
of incremental costs related to the early closure of the Boardman power plant ("Boardman") and
established the Boardman balancing account which tracks the difference between cost and
revenues, including Boardman-related ARO balances. ln addition, Order No. 32549 exempted
Boardman-related ARO balances from the deferraltreatment required under Order No. 29414.
Pursuant to Order No. 29414, attached please find all journal entries made under the
requirements of ASC 410. lf you have any questions regarding this filing, please contact
Regulatory Consultant Courtney Waites at [phone] or [e-mail].
Very truly yours,
