The Company records obligations related to retirement costs of natural gas distribution mains and lines,
decommissioning of certain electric generating facilities, special handling and disposal of hazardous
materials at certain electric generating facilities, natural gas distribution facilities and buildings, and
certain other obligations as asset retirement obligations.
A reconciliation of the Company's liability for the years ended December 31 was as follows:
2021 2020
(In thousands)
Balance at beginning of year $ 354,998 $ 331,897

*Includes $18.6 million and $17.5 million in 2021 and 2020, respectively, recorded to regulatory assets.
The current portion of the Company's asset retirement obligation is included in other accrued liabilities
on the Consolidate Balance Sheets and was $4.4 million and $857,000 at December 31, 2021 and 2020,
respectively.
The Company believes that largely all expenses related to asset retirement obligations will be recovered
in rates over time and, accordingly, defers such expenses as regulatory assets.
Notes to Financial Statements
NOTE 14 – EMPLOYEE BENEFIT PLANS
Pension and other postretirement benefit plans
The Company has noncontributory qualified defined benefit pension plans and other postretirement
benefit plans for certain eligible employees. The Company uses a measurement date of December 31 for
all of its pension and postretirement benefit plans.
Prior to 2013, all of the Company’s defined benefit pension plans were frozen. These employees were
eligible to receive additional defined contribution plan benefits.
Effective January 1, 2010, eligibility to receive retiree medical benefits was modified. Current
employees at Montana-Dakota and Intermountain, and those hired before June 1, 1992 at Cascade, who
had attained age 55 with 10 years of continuous service by December 31, 2010, were provided the
option to choose between a pre-65 comprehensive medical plan coupled with a Medicare supplement or
a specified company funded Retiree Reimbursement Account, regardless of when they retire. All other
eligible employees must meet the new eligibility criteria of age 60 and 10 years of continuous service at
the time they retire to be eligible for a specified company funded Retiree Reimbursement Account.

Employees at Montana-Dakota and Intermountain hired after December 31, 2009, and employees at
Cascade hired after June 1, 1992, will not be eligible for retiree medical benefits.
In 2012, the Company modified health care coverage for certain retirees. Effective January 1, 2013,
post-65 coverage was replaced by a fixed-dollar subsidy for retirees and spouses to be used to purchase
individual insurance through an exchange.

In 2021, the actuarial gain recognized in the benefit obligation was primarily the result of an increase in
the discount rate. In 2020, the actuarial loss recognized in the benefit obligation was primarily the result
of a decrease in the discount rate. For more information on the discount rates, see the table below.
Unrecognized pension actuarial losses in excess of 10 percent of the greater of the projected benefit
obligation or the market-related value of assets are amortized over the average life expectancy of plan
participants for frozen plans. The market-related value of assets is determined using a five-year average
of assets.
Notes to Financial Statements
The pension plans all have accumulated benefit obligations in excess of plan assets. The projected
benefit obligation, accumulated benefit obligation and fair value of plan assets for these plans at
December 31 were as follows:

Weighted average assumptions used to determine benefit obligations at December 31 were as follows:
Pension Benefits Other Postretirement Benefits
2021 2020 2021 2020
Discount rate 2.64%2.30%2.65%2.28%
Expected return on plan assets 6.00%6.00%5.50%5.50%
Weighted average assumptions used to determine net periodic benefit cost (credit) for the years ended
December 31 were as follows:
Pension Benefits Other Postretirement Benefits

Discount rate 2.30%2.96%2.28%2.97%
Expected return on plan assets 6.00%6.25%5.50%5.75%
The expected rate of return on pension plan assets is based on a targeted asset allocation range
determined by the funded ratio of the plan. As of December 31, 2021, the expected rate of return on
pension plan assets is based on the targeted asset allocation range of 35 percent to 45 percent equity
securities and 55 percent to 65 percent fixed-income securities and the expected rate of return from these
asset categories. The expected rate of return on other postretirement plan assets is based on the targeted
asset allocation of 10 percent equity securities and 90 percent fixed-income securities and the expected
rate of return from these asset categories. The expected return on plan assets for other postretirement
benefits reflects insurance-related investment costs.
Health care rate assumptions for the Company's other postretirement benefit plans as of December 31
were as follows:
2021 2020
Health care trend rate assumed for next year 7.0 % 7.0 %
Health care cost trend rate – ultimate 4.5 % 4.5 %
Year in which ultimate trend rate achieved 2031 2031
The Company's other postretirement benefit plans include health care and life insurance benefits for
certain retirees. The plans underlying these benefits may require contributions by the retiree depending
on such retiree's age and years of service at retirement or the date of retirement. The Company
contributes a flat dollar amount to the monthly premiums, which is updated annually on January 1.
Notes to Financial Statements
In 2019, the Company contributed an additional $12.4 million to its defined benefit pension plans, which
increased the funded status and decreased future expenses for the plans. The Company does not expect
to contribute to its defined benefit pension and postretirement benefit plans in 2020.

The Company does no expect to contribute to its defined benefit pension plans in 2022 due to an
additional $12.4 million contributed to the plans in 2019 creating prefunding credits to be used in future
years. The Company expects to contribute approximately $26,000 to its postretirement benefit plans in

Outside investment managers manage the Company's pension and postretirement assets. The Company's
investment policy with respect to pension and other postretirement assets is to make investments solely
in the interest of the participants and beneficiaries of the plans and for the exclusive purpose of
providing benefits accrued and defraying the reasonable expenses of administration. The Company
strives to maintain investment diversification to assist in minimizing the risk of large losses. The
Company's policy guidelines allow for investment of funds in cash equivalents, fixed-income securities
and equity securities. The guidelines prohibit investment in commodities and futures contracts, equity
private placement, employer securities, leveraged or derivative securities, options, direct real estate
investments, precious metals, venture capital and limited partnerships. The guidelines also prohibit short
selling and margin transactions. The Company's practice is to periodically review and rebalance asset
categories based on its targeted asset allocation percentage policy.
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an
exit price) in an orderly transaction between market participants at the measurement date. The fair value
ASC establishes a hierarchy for grouping assets and liabilities, based on the significance of inputs. The
estimated fair values of the Company's pension plans’ assets are determined using the market approach.
The carrying value of the pension plans’ Level 2 cash equivalents approximates fair value and is
determined using observable inputs in active markets or the net asset value of shares held at year end,
which is determined using other observable inputs including pricing from outside sources.
The estimated fair value of the pension plans’ Level 1 equity securities is based on the closing price
reported on the active market on which the individual securities are traded. The estimated fair value of
the pension plans’ Level 1 and Level 2 collective and mutual funds are based on the net asset value of
shares held at year end, based on either published market quotations on active markets or other known
sources including pricing from outside sources. The estimated fair value of the pension plans’ Level 2
corporate and municipal bonds is determined using other observable inputs, including benchmark yields,

reported trades, broker/dealer quotes, bids, offers, future cash flows and other reference data. The
estimated fair value of the pension plans’ Level 1 U.S. Government securities are valued based on
quoted prices on an active market. The estimated fair value of the pension plans’ Level 2 U.S.
Government securities are valued mainly using other observable inputs, including benchmark yields,
reported trades, broker/dealer quotes, bids, offers, to be announced prices, future cash flows and other
reference data. Some of these securities are valued using pricing from outside sources.
All investments measured at net asset value in the tables that follow are invested in commingled funds,
separate accounts or common collective trusts which do not have publicly quoted prices. The fair value
of the commingled funds, separate account and common collective trusts are determined based on the
net asset value of the underlying investments. The fair value of the underlying investments held by the
commingled funds, separate account and common collective trusts is generally based on quoted prices in
active markets.
Though the Company believes the methods used to estimate fair value are consistent with those used by
other market participants, the use of other methods or assumptions could result in a different estimate of
fair value.

General Description of Construction Overhead Procedure
1.For each construction overhead explain: (a) the nature and extent of work, etc., the overhead charges are intended to cover, (b)
the general procedure for determining the amount capitalized, (c) the method of distribution to construction jobs, (d) whether
different rates are applied to different types of construction, (e) basis of differentiation in rates for different types of construction,
and (f) whether the overhead is directly or indirectly assigned.
2.Show below the computation of allowance for funds used during construction rates, in accordance with the provisions of Gas Plant
Instructions 3 (17) of the Uniform System of Accounts.
3.Where a net-of-tax rate for borrowed funds is used, show the appropriate tax effect adjustment to the computations below in a
manner that clearly indicates the amount of reduction in the gross rate for tax effects.
Engineering & Supervision and General & Administrative overhead:
Engineering & Supervision (ES) overhead consists of employees' time in preparation of work orders, mapping, determining feasibility, and other Engineering/construction based supervisory costs related to new construction which are not identified with a specific project, along with the associated payroll taxes and employee benefit costs.
General & Administrative (GA) overhead consists of employees' time in processing A/P, A/R, receiving orders, and other administrative
functions which are not identified with a specific project, along with the associated payroll taxes and employee benefit costs.
Both ES & GA (ES/GA) are accumulated in pools from which a portion is allocated each month. The allocation is based on a rate determined by the Fixed Asset Accounting Analyst and approved by the Controller which is then applied to the current month activity for all applicable work orders to determine how much should be transferred from the ES/GA pools to the affected work orders. This is accomplished via a system (PowerPlan) batch operation. An applicable work order is one that is capital installation/purchase, and not a preliminary survey or investigative
in nature. Note that purchase projects only receive GA overhead, not ES. Construction projects receive both.

Accumulated Provision for Depreciation of Gas Utility Plant (Account 108)
1.Explain in a footnote any important adjustments during year.
2.Explain in a footnote any difference between the amount for book cost of plant retired, line 10, column (c), and that reported for gas
plant in service, page 204-209, column (d), excluding retirements of nondepreciable property.
3.The provisions of Account 108 in the Uniform System of Accounts require that retirements of depreciable plant be recorded when such
plant is removed from service. If the respondent has a significant amount of plant retired at year end which has not been recorded and/
or classified to the various reserve functional classifications, make preliminary closing entries to tentatively functionalize the book cost of
the plant retired. In addition, include all costs included in retirement work in progress at year end in the appropriate functional
classifications.
4.Show separately interest credits under a sinking fund or similar method of depreciation accounting.
5.At lines 7 and 14, add rows as necessary to report all data. Additional rows should be numbered in sequence, e.g., 7.01, 7.02, etc.
