Case No. IPC-E-03-11
Annual Compliance Filing of Asset Retirement Obligations ("ARO")
Accounting Standards Codification ("ASC") 41 0
Dear Ms. Jewell
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 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. 32549 was issued authorizing the Company to 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 deferral treatment required
under Order No. 29414.
Pursuant to Order No. 29414, attached please find three copies of alljournal entries
made under the requirements of ASC 410. lf you have any questions regarding this filing,
please contact Senior Regulatory Analyst Courtney Waites at [phone] or
cwa ites@idahopower. com.
Sincerely,
LDN/KKI
