The quantification and classification of excess defened income taxes associated
with accumulated deferred income taxes maintained in the Company's tax fixed
asset system, PowerTax, is made out-of-system and the change in classification
resulted from refinements to that analysis. In order to provide transparency to the
changes, a "toggle" has been included in the Report 170 Summary tab of
Confidential Attachment PIIC 3 I't Supp, When cell Hl of the tab is populated with
ffi X, the workbook reports the values used for the June 15, 2018, Final Report.
When cell H1 is populated with no value, the workbook reports the revised values.
The change is summarized in rows 72-84 of the Summary tab.
Confidential information is provided subject to the protective agreement in place
in this case.
