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, 2018 and 2017 were
as follows:

(in thousands) Total Level 1 Level 2 Level 3
Liabilities:
Interest rate swap $ (263) §$ - $ (263) §$ -

Operating Leases

The Company’s corporate office space, as well as certain office equipment, is leased under
operating lease agreements. Total rent expense was approximately $367,400 and $309,800 for
the years ended December 31, 2018 and 2017, respectively.

The remaining non-cancelable lease commitments for the corporate office space and leased
equipment as of December 31, 2018 were as follows:

(in thousands) Amount
2019 $ 356
2020 344
2021 345
2022 203
Total $ 1,248

The following 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):

(in thousands) 2018 2017
Balance, beginning of year $ 3,215 $ 2,264
Plan transfers 1,548 1,314
Contributions 219 222
Benefits paid (645) (651)
Return on plan assets (net of investment expenses) 77 66
Balance, end of year $ 4,414 $ 3,215

The fair value of DB Plan and OPEB Plan assets by levels within the fair value hierarchy used
as of December 31, 2017 was as follows:

A fair value hierarchy which prioritizes the inputs to valuation methods is used to measure fair
value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets
for identical assets or liabilities (Level | measurements) and the lowest priority to unobservable
inputs (Level 3 measurements).

The fair value of DB Plan and OPEB Plan assets by levels within the fair value hierarchy used
as of December 31, 2018 was as follows:

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, 2017, as well as
the targeted allocation range:

DB Plan OPEB Plans
Asset Asset
Allocation Allocation
Range Range
Equities 63% 30% - 100% 69% 30% - 100%
Fixed income 37% 20% - 70% 29% 0% - 50%
Cash and cash equivalents 0% 0% - 15% 2% 0% - 15%
Total 100% 100%

The key assumptions used to value benefit obligations and calculate net periodic benefit cost
for our DB and OPEB Plans include the following:

2018 2017
Discount rate for net periodic benefit cost, beginning of year 3.50% 4.02%
Discount rate for benefit obligations, end of year (a) 4.15% 3.50%
Expected return on plan assets for the period (net of investment expenses) 7.00% 7.00%
Rate of compensation increase, beginning of year 3.00% 3.00%
Healthcare cost trend rate (applicable only to OPEB Plans) 7.00% 7.50%

Changes in plan assets and benefit obligations recognized in regulatory assets, for the year
ended December 31, 2018, were as follows:

(in thousands) DB Plan OPEB Plans
Regulatory asset balance, beginning of period $ 7,593 $ 651
Net actuarial loss incurred during the period 374 (77)
Prior service cost incurred during the period - 16
Recognized net actuarial (gain)/loss (335) (25)
Regulatory asset balance, end of period $ 7,632 $ 565
