PIIC Data Response 3 2nd Supplemental
Further to the Company's response to PIIC Data Request 3 lstSupplemental dated
July 25, 2018, the Company provides the following additional information.
Please see Confidential Attachment PIIC 3 2nd Supplemental for an updated
supporting file for the quantification and classification of EDIT, the results of
which are summarized below. The Excel workbook is password protected to give
users the option to view the workbook as read-only so as to avoid inadvertent
modifications. For write access, the password is: taxreform.
In August 2018, the Internal Revenue Service issued proposed regulations that
address the bonus depreciation rules under the new tax law. Based on those
proposed regulations, the Company is now taking 100 percent bonus depreciation
on qualiffing public utility property placed in service between Septanber 27,
2017, and December 31, 2017, where none had been taken on that property in the
calculations that formed the basis of the amounts provided in the Company's
response to Data Request PllC 3 I't Supplemental. The update for bonus
depreciation generated additional EDIT of $8.1 million on a total company basis
and $0.4 million on an ldaho basis, with a vast majority of this balance being
classifi ed as protected property-related EDIT.
