Revenue from Contracts with Customers — Non-Regulated Entities

Revenue is recognized when control of the promised goods or services is transferred to
customers, in an amount that reflects the consideration we expect to be entitled to in
exchange for those goods or services.

over time totaled $2,777,693 and $2,892,868, respectively.

For assets and liabilities measured at fair value on a recurring basis, the fair value measure-
ment by levels within the fair value hierarchy used as of December 31, 2020 and 2019 were
as follows:

The foilowing table presents a period-end reconciliation of DB Plan assets measured and
recorded at fair value on a recurring basis, using significant unobservable inputs (Level 3):

The fair value of DB Plan and OPEB Plan assets by levels within the fair value hierarchy used
as of December 31, 2019 was as follows:

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:

DB Plan OPEB Plans
Asset Asset
Allocation Allocation
Range Range
Equities 61% 30% - 100% 69% 30% - 100%
Fixed income 39% 20% - 70% 29% 0% - 50%
Cash and cash equivalents 0% 0% - 15% 2% 0% - 15%
Total 100% 100%

The estimated net actuarial loss for our DB Plan that will be amortized in 2021 from the
regulatory assets into net periodic benefit costs is $625,000. The estimated net actuarial gain
and prior service cost for our OPEB Plans that will be amortized in 2021 from the regulatory
assets into net periodic benefit costs is $60,200.
