Agenda

The methods described above may produce a fair value calculation that may not be indicative of
net realizable value or reflective of future fair values. Furthermore, while the Plan’s management
believes the valuation methodologies are appropriate and consistent with other market
participants, the use of different methodologies or assumptions to determine the fair value of
certain investments could result in a different fair value measurement at the reporting date.

The following table indicates the asset allocation percentages of the fair value of the DB Plan
and OPEB Plans’ assets for each major type of plan asset as of December 31, 2019, as well as
the targeted allocation range:

Cash and cash equivalents 0% 0% - 15% 2% 0% - 15%
