Compensation And Retirement Disclosure [Abstract] |
Pension and Other Benefit Plans | 17. Pension and Other Benefit Plans Pension Plans Schlumberger sponsors several defined benefit pension plans that cover substantially all US employees hired prior to October 1, 2004. The benefits are based on years of service and compensation, on a career-average pay basis. In addition to the US defined benefit pension plans, Schlumberger sponsors several other international defined benefit pension plans. The most significant of these international plans are the International Staff Pension Plan and the UK pension plan (collectively, the “International plans”). The International Staff Pension Plan covers certain international employees hired prior to July 1, 2014 and is based on years of service and compensation on a career-average pay basis. The UK plan covers employees hired prior to April 1, 1999, and is based on years of service and compensation, on a final salary basis. The weighted-average assumed discount rate, compensation increases and expected long-term rate of return on plan assets used to determine the net pension cost for the US and International plans were as follows:
| US |  |  | International |

Certain of Schlumberger’s deferred benefit pension plans offered former Schlumberger employees, who had not yet commenced receiving their pension benefits, an opportunity to receive a lump sum payout of their vested pension benefit. Schlumberger’s pension plans paid $257 million from pension plan assets to those who accepted this offer, thereby reducing its pension benefit obligations. These transactions resulted in a non-cash pension settlement charge of $37 million, representing the immediate recognition of the related deferred actuarial losses in Accumulated Other Comprehensive Loss, in the fourth quarter of 2019. See Note 3 – Charges and Credits. The weighted-average assumed discount rate and compensation increases used to determine the projected benefit obligations for the US and International plans were as follows:

The unfunded liability represents the difference between the plan assets and the projected benefit obligation (“PBO”). The PBO represents the actuarial present value of benefits based on employee service and compensation and includes an assumption about future compensation levels. The accumulated benefit obligation (“ABO”) represents the actuarial present value of benefits based on employee service and compensation but does not include an assumption about future compensation levels. Actuarial losses arising during 2020 and 2019 were primarily attributable to decreases in the discount rate used to determine the PBO. As of December 31, 2020, the PBO and fair value of plan assets for plans with PBOs in excess of plan assets were $9.4 billion and $8.3 billion, respectively. The related ABO for these plans was $9.1 billion at December 31, 2020. The weighted-average allocation of plan assets and the target allocations by asset category are as follows:
| US |  |  |  | International |
| Target |  |  |  | 2020 |  |  |  | 2019 |  |  |  | Target |  |  |  | 2020 |  |  |  | 2019 |

Asset performance is monitored frequently with an overall expectation that plan assets will meet or exceed the weighted index of its target asset allocation and component benchmark over rolling five-year periods. The expected rate of return on assets assumptions reflect the long-term average rate of earnings expected on funds invested or to be invested. The assumptions have been determined based on expectations regarding future rates of return for the portfolio considering the asset allocation and related historical rates of return. The appropriateness of the assumptions is reviewed annually. The fair value of Schlumberger’s pension plan assets at December 31, 2020 and 2019, by asset category, is presented below and was determined based on valuation techniques categorized as follows:
| • | Level One: The use of quoted prices in active markets for identical instruments.
| • | Level Two: The use of quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active or other inputs that are observable in the market or can be corroborated by observable market data.
| • | Level Three: The use of significant unobservable inputs that typically require the use of management’s estimates of assumptions that market participants would use in pricing.

(a) | US equities include companies that are well-diversified by industry sector and equity style (i.e., growth and value strategies). Active and passive management strategies are employed. Investments are primarily in large capitalization stocks and, to a lesser extent, mid- and small-cap stocks.
(b) | International equities are invested in companies that are traded on exchanges outside the US and are well-diversified by industry sector, country and equity style. Active and passive strategies are employed. The vast majority of the investments are made in companies in developed markets, with a small percentage in emerging markets.
(c) | Corporate bonds consist primarily of investment grade bonds from diversified industries.
(d) | Government and government-related debt securities are comprised primarily of inflation-protected US treasuries and, to a lesser extent, other government-related securities.
(e) | Collateralized mortgage obligations and mortgage backed-securities are debt obligations that represent claims to the cash flows from pools of mortgage loans, which are purchased from banks, mortgage companies, and other originators and then assembled into pools by governmental, quasi-governmental and private entities.
(f) | Private equity includes investments in several funds of funds.

Schlumberger’s funding policy is to annually contribute amounts that are based upon a number of factors including the actuarial accrued liability, amounts that are deductible for income tax purposes, legal funding requirements and available cash flow. Schlumberger expects to contribute approximately $20 million to its postretirement benefit plans in 2021, subject to market and business conditions. Postretirement Benefits Other Than Pensions Schlumberger provides certain healthcare benefits to certain former US employees who have retired. Effective April 1, 2015, Schlumberger changed the way it provides healthcare coverage to certain retirees who are age 65 and over. Under the amended plan, these retirees transferred to individual coverage under the Medicare Exchange. Schlumberger subsidizes the cost of the program by providing these retirees with a Health Reimbursement Account. The annual subsidy may be increased based on medical cost inflation, but it will not be increased by more than 5% in any given year. The actuarial assumptions used to determine the accumulated postretirement benefit obligation and net periodic benefit cost for the US postretirement medical plan were as follows:
| Benefit Obligations |  |  | Net Periodic Benefit |
| At December 31, |  |  | Cost for the Year |
| 2020 |  |  | 2019 |  |  | 2020 |  |  | 2019 |  |  | 2018 |

Current medical cost trend rate |  | 7.25 | % |  |  | 7.50 | % |  |  | 7.25 | % |  |  | 7.50 | % |  |  | 7.00 | %
Ultimate medical cost trend rate |  | 4.50 | % |  |  | 4.50 | % |  |  | 4.50 | % |  |  | 4.50 | % |  |  | 5.00 | %

The net periodic benefit credit for the US postretirement medical plan included the following components:

Due to the actions taken by Schlumberger to reduce its global workforce during 2020, Schlumberger experienced a significant reduction in the expected aggregate years of future service of its employees in its US postretirement medical plan. Accordingly, Schlumberger recorded a curtailment gain of $69 million during the second quarter of 2020 relating to this plan. The curtailment gain includes recognition of the decrease in the benefit obligation as well as a portion of the previously unrecognized prior service credit, reflecting the reduction in expected years of future service. As a result of the curtailment, Schlumberger performed a remeasurement of the plan, which had an immaterial impact. This gain was classified in Impairments & other in the Consolidated Statement of Loss. See Note 3 – Charges and Credits.
