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.

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 qualifying public utility property placed in service between September 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 PIIC 3 1st Supplemental. The update for bonus depreciation generated additional EDIT of $8.1 million on a total company basis and $0.4 million on an Idaho basis, with a vast majority of this balance being classified as protected property-related EDIT.
Confidential information is provided subject to the protective agreement in place in this case.
