Dear Ms. Jewell:
On November 18, 2013, the Idaho Public Utilities Commission approved an all-party stipulation
in Case No. PAC-E-13-02. Paragraph 2l of the Commission Order states:

keep the Stipulating Parties and the Utah, Idaho and Wyoming Commissions
informed regarding any matters likely to have implications regarding potential
stranded costs of generating assets. The Company will propose a reporting
method by no later than December 31,2013.
Per this commitment, Rocky Mountain Power proposes to implement a reporting system that

significant implications on the Company's depreciation expense. On or before March I of every
year, the Company will file a letter containing the following information, if applicable.
