Retirement Benefits [Abstract]  
Pension and Other Post-Retirement Benefit Plans PENSION AND OTHER POST-RETIREMENT BENEFIT PLANS
Washington Gas maintains a qualified, trusteed, non-contributory defined benefit pension plan (qualified pension plan) covering most active and vested former employees of Washington Gas and certain employees of WGL subsidiaries. The non-contributory defined benefit pension plan is closed to all employees hired on or after January 1, 2010 and instead employees are eligible to receive supplemental contributions to their defined-contribution savings plan.
Several executive officers of Washington Gas also participate in a defined benefit supplemental executive retirement plan (DB SERP), a non-qualified pension plan. The DB SERP was closed to new entrants beginning January 1, 2010 and instead, executive officers are eligible to participate in a defined contribution SERP (DC SERP). In addition, effective January 1, 2010, Washington Gas established a non-funded defined benefit restoration plan (DB restoration) for the purpose of providing supplemental pension and pension-related benefits to a select group of management employees. There are rabbi trusts associated with the DB SERP and DB restoration plans that were funded pursuant to the Merger Agreement. The rabbi trusts can be used to make payments to the participants or the payments can be made from operating funds. At December 31, 2020, the rabbi trust balance associated with these two plans were $18.8 million, of which $6.7 million was recorded in “Current Assets-Other” and $12.1 million was recorded in “Deferred Charges and Other Assets - Other”, along with other rabbi trust balances. Washington Gas accounts for the qualified pension plan, DB SERP and DB restoration plans under the provisions of ASC Topic 715, Compensation-Retirement Benefits.
Washington Gas offers defined-contribution savings plans to all eligible employees. These plans allow participants to defer on a pre-tax or after-tax basis, a portion of their salaries for investment in various alternatives. We made matching contributions of $5.6 million, $5.2 million, $1.1 million and $5.0 million during the calendar years ended December 31, 2020 and 2019, three months ended December 31, 2018, and fiscal year ended September 30, 2018, respectively. All employees not earning benefits in the qualified pension plan receive an employer provided supplemental contribution ranging from 4% to 6% depending on years of service. Total supplemental contributions to the plans were $3.8 million, $3.2 million, $0.7 million and $2.7 million during the calendar year ended December 31, 2020 and 2019, three months ended December 31, 2018, and fiscal year ended September 30, 2018, respectively.
Washington Gas provides certain healthcare and life insurance benefits for retired employees of Washington Gas and certain employees of WGL subsidiaries. Substantially all employees of Washington Gas may become eligible for such benefits if they attain retirement status while working for Washington Gas. For eligible retirees and dependents not yet receiving Medicare benefits, Washington Gas provides medical, prescription drug and dental benefits through the Washington Gas Light Company Retiree Medical Plan (Retiree Medical Plan). For Medicare-eligible retirees age 65 and older, eligible retirees and dependents participate in a special tax-free Health Reimbursement Account plan (HRA plan) effective January 1, 2015. Participating retirees and dependents receive an annual subsidy to help purchase supplemental medical, prescription drug and dental coverage in the marketplace as well as additional reimbursement for catastrophic prescription drug costs. Washington Gas accounts for healthcare and life insurance benefits under the provisions of ASC Topic 715.
On September 25, 2015, the Retiree Medical Plan was amended to limit the aggregate cost of applicable employer-sponsored coverage, thereby avoiding the 40% excise tax enacted by the Patient Protection and Affordable Care Act of 2010. The resolution, which was effective September 30, 2015 applies to plan years beginning on or after January 1, 2018.
Almost all costs associated with Washington Gas’ defined benefit post-retirement plans have historically been, and are expected to be, recovered through Washington Gas’ rates. Therefore, in accordance with ASC Topic 980 and ASC Topic 715, Washington Gas established a regulatory asset/liability for the substantial majority of the unrecognized costs/income associated with its defined benefit post-retirement plans. To the extent these amounts will not be recovered through Washington Gas’ rates, they are recorded directly to “Accumulated other comprehensive loss, net of taxes.”
Change in Accounting Principle
During the third quarter of 2020, Washington Gas made a voluntary change in accounting principle for calculating the MRVA used in the determination of net periodic pension and other post-retirement benefit plan costs. The effect of the change on pension and other post-retirement plans has been adjusted to the periods presented herein. Refer to Note 1— Accounting Policies for further discussion.

The following table provides amounts recorded to regulatory assets, regulatory liabilities and accumulated other comprehensive loss (income) at December 31, 2020 and 2019. The decrease in the actuarial net loss related to pension benefits and increase in the actuarial gain related to health and life benefits at December 31, 2020 compared to 2019 were due to the actual return on plan assets being higher than expected.

Washington Gas uses the MRVA in the determination of net periodic benefit cost. Realized and unrealized gains and losses for assets under Washington Gas’ post-retirement benefit plans are recognized immediately for fixed income securities and are spread over a period of five years for all other asset classes. The fair value approach is used for the fixed income investments and related derivatives. For all other asset classes gains and losses arising from changes in fair value are deferred and amortized into the calculation of the MRVA over a period of five years. Each year 20% of the prior five years’ asset gains and losses are recognized.
We use the corridor approach to amortize actuarial gains and losses. Under this approach, net gains or losses in excess of ten percent of the larger of the benefit obligation or the MRVA are amortized on a straight-line basis.

(b) "Other Adjustments” in 2019 represents the one-time charge associated with the temporary deviation in the substantive plan of delaying the cap on pre-65
retiree medical benefits to 2021.
© On October 1, 2018, Washington Gas prospectively adopted ASU 2017-07. As a result, only the service cost component of net periodic benefit costs (income) is eligible for capitalization.
(d) Amounts represents the amortization of previously unrecovered costs of the applicable pension benefits or the health and life benefits as approved in the District of Columbia through 2019. The amounts were fully amortized as of December 31, 2019
On October 1, 2018, Washington Gas adopted ASU 2017-07. This standard requires entities to report the service cost component in the same financial statement line item as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are to be presented separately from service cost and outside of operating income. Washington Gas includes the other components in "Other Income (expense)-net" on the Statement of Operations. In addition, only the service cost component of net benefit cost is eligible for capitalization. Changes to the presentation of service costs and other components of net benefit cost were applied retrospectively. As a result of the retrospective adoption, we reclassified $11.3 million of net periodic benefit income from "Operation and maintenance" expense to "Other income (expense)-net" on the statements of operations for the fiscal year ended September 30, 2018. Changes in capitalization practices were implemented prospectively.

(b) For health and life benefits, the expected returns for certain funds may be lower due to certain portions of income that are subject to an assumed blended income tax rate of 33.32%.
(c) The changes in the rate of compensation reflects the best estimates of actual future compensation levels including consideration of general price levels, productivity, seniority, promotion, and other factors such as inflation rates.
Discount Rate
Washington Gas determines the discount rate based on a portfolio of high quality fixed-income investments (AA- as assigned by Standard & Poor’s or Aa3 as assigned by Moody’s or better) whose cash flows would cover our expected benefit payments.
Expected long-term return on plan assets
Washington Gas determines the expected long-term rate of return on plan assets by averaging the expected earnings for the target asset portfolio. In developing the expected rate of return assumption, Washington Gas evaluates an analysis of historical actual performance and long-term return projections, which gives consideration to our asset mix and anticipated length of obligation of our plan.
Mortality Assumptions
Beginning in October 2014, the SOA began publishing annual updates to its mortality tables for U.S. plans, starting with the RP-2014 base mortality table and the MP-2014 improvement scale. The improvement scale has been updated each year.
In October 2020, the SOA issued and updated improvement scale (MP-2020). The MP-2020 improvement scale and the Pri-2012 (the Private Retirement Plans Mortality table for 2012) mortality table were used to determine the benefit obligation as of December 31, 2020.
In October 2019, the SOA issued an updated base mortality table (Pri-2012) as well as an updated improvement scale (MP-2019). The white-collar Pri-2012 mortality table and MP-2019 improvement scale were used to determine the benefit obligation as of December 31, 2019.
Healthcare cost trend
Washington Gas assumed the healthcare cost trend rates related to the accumulated post-retirement benefit obligation at December 31, 2020, for non-Medicare eligible retirees, to be 2.2% starting in 2021 and expects the trend to remain at that level thereafter. 
Washington Gas assumed the healthcare cost trend rates related to the accumulated post-retirement benefit obligation at December 31, 2019, for non-Medicare eligible retirees, to be 6.25% for calendar year 2020 and expected the trend rate to decrease to 2.0% in calendar year 2021 and remain at that level thereafter.
For Medicare eligible retirees age 65 and older that will receive a subsidy each year as a benefit from the HRA plan, Washington Gas assumed no increase to the annual subsidy in calendar years 2021 - 2025, 4.0% increase in calendar year 2026 and 2% increase in calendar year 2027 and thereafter in order to approximate possible future increases to the stipend. While the plan terms do not guarantee increases to the stipend, Washington Gas intends to review the stipend annually.
Investment Policies and Strategies
The investment objective of the qualified pension, healthcare, and life insurance benefit plans (“Plan” or “Plans”) is to allocate each Plan’s assets to appropriate investment asset classes (asset categories) so that the benefit obligations of each Plan are adequately funded, consistent with each Plan’s and Washington Gas’ tolerance for risk.
Washington Gas' portion of retired employee healthcare and life insurance benefits obligation is funded through two trusts: (i) the Washington Gas Light Company Post Retirement Benefit Master Trust for Retired Previously Union-Eligible Employees ("union-eligible trust") and (ii) the Washington Gas Light Company Post Retirement Benefit Master Trust for Retired Management Employees ("management trust").
In order to best achieve the investment objectives for each Plan, strategic allocation targets and ranges are established that control exposure to selected investment asset classes. Asset/Liability Modeling (ALM) is used to test the benefits and risks of several potential strategic asset allocation mixes. Simulated investment performance results based on assumptions about expected return, volatility, and correlation characteristics of the selected asset classes are tested for their effects on contributions, pension expense, PBO funded status, and downside Value at Risk metrics over a ten-year planning time horizon. An ALM study completed in January 2020 indicated that adopted target asset class allocations remained an appropriate trade-off between risk and reward. The following table includes the target asset allocation by asset class at December 31, 2020. Actual asset balances are reviewed monthly and allowed to range within plus or minus 5% of the target allocations. Assets are generally rebalanced to target allocations before actual amounts fall below or rise above the allowable ranges.

(a) The Fixed Income asset class includes the related derivatives.
(b) Investment strategy for the qualified pension plan includes increasing the target fixed income allocation percentage by 10% for each 5% improvement in the Plan’s funded ratio above the 100% funded level.
Significant amounts of each various Plan's assets are managed by the same financial institution. Each Plan has a high exposure to U.S. based investments. There are no other significant risk concentrations related to investments in any entity, industry, country, commodity, or investment fund.
Commingled funds are employed in the management of qualified pension plan, management trust, and union-eligible trust assets. In addition, a publicly offered mutual fund and separately managed portfolios are employed in the management of a qualified pension plan trust. The management trust also uses a separately managed portfolio.
U.S. and international equity assets are diversified across sectors, industries, and investment styles. Fixed income assets are primarily diversified across U.S. government and investment grade corporate debt instruments, with some exposure to foreign and non-investment-grade securities. Real estate is diversified geographically across the U.S. by property type.
The qualified pension plan’s investment policy allows the use of futures, options, and other derivatives for purposes of reducing portfolio risk and as a low- cost option for gaining market exposure, but derivatives may not be used for leverage. Derivatives are currently used in the Fixed Income portion of the portfolio. The qualified pension plan’s investment policy prohibits investments in Washington Gas securities. The prohibition applies to separately managed portfolios but does not apply to any commingled fund investments.

Valuation Methods
Equity securities are traded on a securities exchange and are valued at the closing quoted market price as of the balance sheet date.
Mutual funds, commingled funds, pooled separate accounts and private equity/limited partnerships are valued at the quoted net asset value (NAV) per share, which is computed as of the close of business on the balance sheet date. Mutual funds with a publicly quoted NAV per share are classified as Level 1. The remaining asset types are not classified in the fair value hierarchy.
Fixed income securities are valued using pricing models that consider various observable inputs such as benchmark yields, reported trades, broker quotes and issuer spreads to determine fair value.
Benefit Contribution
For the qualified pension plan, Washington Gas’ funding policy is to contribute an amount sufficient to satisfy the minimum annual funding requirements under the Pension Protection Act. Any contributions above the minimum annual funding requirements would be limited to amounts that are deductible under appropriate tax law. For the healthcare and life insurance benefit plans, Washington Gas’ funding policy is to contribute amounts that are collected from ratepayers.
During the calendar year ended December 31, 2020, Washington Gas did not contribute to its qualified pension but did contribute $20.5 million and $0.5 million to its DB SERP and DB Restoration plans, respectively, which was funded by the rabbi trust. For the calendar year of 2021, Washington Gas does not expect to make a contribution to its qualified pension plan and expects to contribute $7.5 million to its DB SERP and DB restoration plans, which is expected to be funded by the related rabbi trusts. During the calendar year 2020, Washington Gas did not make contributions for its health and life insurance benefit plans. Washington Gas does not expect to make a contribution to its health and life insurance benefit plans year in 2021.

Regulatory Matters
A significant portion of the estimated pension and post-retirement medical and life insurance benefits apply to our regulated activities. Each regulatory commission having jurisdiction over Washington Gas requires it to fund amounts reflected in rates for post-retirement medical and life insurance benefits into irrevocable trusts.
District of Columbia Jurisdiction
The PSC of DC has approved a level of rates sufficient to recover annual costs associated with the qualified pension and other post-retirement benefits. Expenses of the SERP allocable to the District of Columbia are not recovered through rates. On March 3, 2017, the Commission issued an order that continued the amortization for prior unrecovered pension and other post-retirement benefits through 2019.
Maryland Jurisdiction
In Washington Gas’ most recent rate case that was finalized in December 2018, the PSC of MD denied recovery through rates of the expenses of the SERP, resulting in a reclassification of $2.9 million from "Regulatory assets" to "Accumulated other comprehensive loss" on the balance sheet. Prior to December 2018, the PSC of MD approved 50% recovery through rates of the SERP expenses. The PSC of MD has approved a level of rates sufficient to recover pension and other post-retirement benefit costs as determined under GAAP.
Virginia Jurisdiction
On September 28, 1995, the SCC of VA issued a generic order that allowed Washington Gas to recover most costs determined under GAAP for post-retirement medical and life insurance benefits in rates over twenty years. The SCC of VA, however, set a forty-year recovery period of the transition obligation. As prescribed by GAAP, Washington Gas amortizes these costs over a twenty-year period. With the exception of the transition obligation, the SCC of VA has approved a level of rates sufficient to recover annual costs for all pension and other post-retirement medical and life insurance benefit costs determined under GAAP.
