Operating risks
Currency risks
Interest rate risks
A fundamental factor in driving demand for offshore drilling rigs is the level of spending by oil and gas companies on exploration, development, production and maintenance as well as decommissioning activities. This level is to a large extent a function of project sanctioning, which is based on oil and gas companies’ long-term assessment of oil and gas prices impacting their cash flow generation as well as the economics of the offshore exploration and development projects in their portfolios.
Currency risk is the risk that future cash flows will fluctuate because of changes in foreign exchange rates. Currency exposure arises from the Company operating in countries with different local currencies. Revenue is primarily denominated in USD, which is also the presentation currency of the Company, while related operating costs are incurred in both USD and local currencies.  The exposure to changes in foreign exchange rates is generally mitigated by entering into customer contracts where an element of the contract value is in local currency to create a natural hedge between contracted revenue and local operating costs. The Maersk Drilling Group uses foreign exchange forward contracts to hedge any excess exposure, but such hedges are generally not entered into by individual subsidiaries.  Currency exposure is considered insignificant.
Interest rate risk is the risk that future cash flows from financial instruments will fluctuate because of changes in market interest rates. The interest rate exposure arises from loans and other credit facilities carrying floating interest rates.  The Maersk Drilling Group mitigates interest rate exposure by entering into fixed rate loans or interest rate swaps at the parent company level whereas individual subsidiaries generally are funded through loans carrying floating interest rates.
For the Company, safety is a top priority. It is an unwavering commitment, rooted in our Core Values. Safety permeates everything we do and stand for, onshore and offshore, and it is the foundation for delivering reliable and efficient operations to our customers. Our ambition is to have zero serious incidents.</h:ManagementsReview><h:StatementOfCorporateSocialResponsibility contextRef="c405" xml:lang="en">Credit risks
For drilling contracts, credit risk is minimised by undertaking a credit assessment of the counterparty prior to entering into the contracts. Depending on creditworthiness, the Company may seek protection in the form of parent company guarantees, prepayments or other types of collateral.  The Company has a concentration of customers, but is not considered exposed to material credit risks, as the customers are major international oil companies.
At the Company, we firmly believe that by conducting our operations through sustainable practices, we ensure a sound and viable business for the future. We have a responsibility to the people who work for the Company, but also to the people and the environment which are affected by our Company.  In 2020, Maersk Drilling launched one of the industry’s most ambitious sustainability strategies based on three pillars: Sustainable Energy Future, Caring for People, and Responsible Business. During 2021, progress has been made with a special focus on the two main components of the strategy: Climate Action and Diversity &amp; Inclusion.  Maersk Drilling’s sustainability approach is described in further details on our website and in our Sustainability Report which also serves as our reporting pursuant to section 99a of the Danish Financial Statements Act. It can be found online at https://www.maerskdrilling.com/who-we-are/sustainability.</h:StatementOfCorporateSocialResponsibility><c:Revenue contextRef="c405" unitRef="u14"

Reasonable assurance is a high level of assurance but is not a guarantee that an audit conducted in accordance with ISAs and the additional requirements in Denmark will always detect a material misstatement when it exists.

identify and assess the risks of material misstatement of the company financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion.

The Company adheres to the Diversity and Inclusion Policy, which was adopted by the Board of Directors of The Drilling Company of 1972 A/S, the parent company of the Maersk Drilling Group, on 11 February 2021. The Company does not discriminate based on age, gender, nationality, socioeconomic background, disability, religion or sexual orientation. The Company believes that diversity and inclusion can contribute to improved performance and high-quality decision-making and is essential to innovation and organisational learning; critical elements to maintaining our position as a leading player in the offshore drilling industry.  Not only is treating employees with respect deeply aligned with Maersk Drilling’s values and the way business is conducted, but our people comprise the core of Maersk Drilling’s business. Mobilising diverse skillsets and perspectives is and continues to be a competitive advantage and a critical driver of the company’s ongoing transformation. Building an inclusive environment is a crucial enabler of this, and therefore, Diversity and Inclusion formed one of two key focus areas of Maersk Drilling’s sustainability strategy, alongside Climate Action, in 2020. A dedicated D&amp;I plan was developed, with targets and initiatives to make significant progress within a timeframe of three years. Maersk Drilling Group believes in the value of diverse role models at the top and are therefore tackling the industry-specific challenge of gender diversity in leadership. Maersk Drilling is pursuing a significant leap forward on gender diversity to increase female representation on all onshore leadership levels through a female leadership target of 30% across leadership levels, 25% for senior leaders, and 20% for the Executive Leadership Team by end-year 2023. Four intervention areas were designed to be achieved over a three-year period. These intervention areas address structural barriers surrounding HR processes and policies for attracting, recruiting, developing, retaining, and appointing diverse talent.  To emphasize the focus on the female representation area and drive visible progress towards 30% representation across all onshore leadership levels by 2023, a specific minimum target of 27% female representation has been integrated into Maersk Drilling’s annual scorecard. Maersk Drilling is currently seeing good progress on our targets. In 2021, the share of female employees stayed the same from 14% in 2020 to 14% in 2021. Onshore, women represent 40% of the workforce. Female leaders made up 28% of onshore leadership in 2021 compared to 25% in 2020. Offshore, women only make up 2% of the workforce. Regarding the Executive Leadership team of the Drilling Company of 1972 A/S, a new female CFO started in January 2021, bringing the female representation to 25%.  At the same time, Maersk Drilling Group is focusing on inclusion in the company to truly make diversity thrive. In addition to the leadership target, Maersk Drilling Group is targeting four focus areas:  - Attracting and hiring female talent by removing bias from our recruitment process.  - Promoting impactful leadership careers through a more inclusive approach to talent identification and    development.  - Transitioning to greater flexibility in ways of working and making inclusive leadership part of our    leadership development programs.  - Showing senior leadership commitment and increasing awareness across the company.</h:StatementOfTargetFiguresAndPoliciesForTheUnderrepresentedGender><c:InformationOnReportingClassOfEntity contextRef="c405" xml:lang="en">The annual report of Maersk Drilling A/S for 2021 has been prepared in accordance with the provisions applying to reporting class C large entities under the Danish Financial Statements Act.</c:InformationOnReportingClassOfEntity><c:InformationOnOmissionOfConsolidatedFinancialStatement contextRef="c405" xml:lang="en">Pursuant to section 112(1) of the Danish Financial Statements Act, no consolidated financial statements have been prepared.

Cost comprises the purchase price and any costs directly attributable to the acquisition until the date on which the asset is available for use. Indirect production overheads and borrowing costs are not recognised in cost. 

The basis of depreciation is cost less any projected residual value after the end of the useful life. Depreciation is provided on a straight-line basis over the estimated useful life. The estimated useful lives are as follows:
The useful life and residual value are reassessed annually. Changes are treated as accounting estimates, and the effect on depreciation is recognised prospectively.

Fixed assets under construction are recognised and measured at cost at the balance sheet date. Upon entry into service, the cost is transferred to the relevant group of property, plant and equipment.

Equity investments in subsidiaries and associates with negative net asset values are measured at DKK 0, and any receivables from these entities are written down to the extent that the receivables are deemed irrecoverable. To the extent that the Parent Company has a legal or constructive obligation to cover a negative balance exceeding the receivable, the residual amount is recognised as provisions.

Equity investments in subsidiaries with negative net asset values are measured at DKK 0, and any receivables from these entities are written down by an amount equivalent to the negative net asset value. To the extent that the negative net asset value exceeds the receivable, the residual amount is recognised as provisions.

Net revaluation of equity investments in subsidiaries is tied as a net revaluation reserve under equity according to the equity method to the extent that the carrying amount exceeds cost. Dividends from group entities expected to be adopted in the group entities prior to the approval of the Company's annual report are not tied up in the revaluation reserve.</c:DescriptionOfMethodsOfRecognitionAndMeasurementBasisOfInvestments><c:DescriptionOfMethodsOfAmortisationOfNoncurrentAssets contextRef="c405" xml:lang="en">The carrying amount of intangible assets and property, plant and equipment as well as equity investments in subsidiaries is subject to an annual test for indications of impairment other than the decrease in value reflected by depreciation or amortisation.

Impairment tests are conducted of individual assets or groups of assets when there is an indication that they may be impaired. Write-down is made to the recoverable amount if this is lower than the carrying amount.

The recoverable amount is the higher of an asset's net selling price and its value in use. The value in use is determined as the present value of the forecast net cash flows from the use of the asset or the group of assets, including forecast net cash flows from the disposal of the asset or the group of assets after the end of the useful life.</c:DescriptionOfMethodsOfAmortisationOfNoncurrentAssets><c:DescriptionOfMethodsOfRecognitionAndMeasurementBasisOfReceivables contextRef="c405" xml:lang="en">Receivables are measured in the balance sheet at the lower of amortised cost and net realisable value, which corresponds to nominal value less write-down for bad debts.

Deferred tax is measured using the balance sheet liability method on all temporary differences between the carrying amount and the tax value of assets and liabilities based on the planned use of the asset or settlement of the liability. However, deferred tax is not recognised on temporary differences relating to goodwill non-deductible for tax purposes and on office premises and other items where the temporary differences arise at the date of acquisition without affecting either profit/loss or taxable income. 

Deferred tax assets, including the tax value of tax loss carryforwards, are recognised at the expected value of their utilisation within the foreseeable future; either as a set-off against tax on future income or as a set-off against deferred tax liabilities in the same legal tax entity. Any deferred net assets are measured at net realisable value.

Deferred tax is measured in accordance with the tax rules and at the tax rates applicable at the balance sheet date when the deferred tax is expected to crystallise as current tax. Changes in deferred tax as a result of changes in tax rates are recognised in the income statement or equity, respectively.</c:DescriptionOfMethodsOfRecognitionAndMeasurementBasisOfTaxPayablesAndDeferredTax><c:DescriptionOfMethodsOfRecognitionAndMeasurementBasisOfLiabilitiesOtherThanProvisions contextRef="c405" xml:lang="en">Financial liabilities are measured at amortised cost, which essentially corresponds to nominal value.</c:DescriptionOfMethodsOfRecognitionAndMeasurementBasisOfLiabilitiesOtherThanProvisions><c:DescriptionOfMethodsOfRecognitionAndMeasurementBasisOfDeferredIncomeLiabilities contextRef="c405" xml:lang="en">Deferred income comprises progress billing regarding income in subsequent years.</c:DescriptionOfMethodsOfRecognitionAndMeasurementBasisOfDeferredIncomeLiabilities><c:DisclosureOfAnyUncertaintyConnectedWithRecognitionOrMeasurement contextRef="c405" xml:lang="en">In 2020, measures to contain the spread of COVID-19 led to an unprecedented decline in demand for oil and gas. Simultaneously, intervention by OPEC+ in the form of historic production cuts were insufficient to offset the decline in oil and gas demand. As a result, Brent oil prices dropped from pre-COVID levels of USD 50-70 to USD 20-40 per barrel.  Following a challenging 2020, an improving outlook for global oil and gas demand caused Brent oil prices to recover to between USD 70-85 per barrel, the highest levels since 2014, spurring an increase in the demand for, and the utilisation of, offshore drilling rigs. This has provided support to day rates, which gradually increased throughout 2021 from COVID-19 lows, especially in the global floater segment. Given current oil and gas prices and rationalisations on the supply side, Management expects this trend to continue throughout 2022.  Following the revised market outlook with higher expectations as to utilisation and day rates for the coming years, the impairment test did not lead to an impairment or reversal of previously recognised impairments at group level, however Management has recognised a profit in net share results of investments in subsidiaries of USD 312 million. That was mainly a result of positive net results achieved by Maersk Drilling North Sea, which was mainly driven the sale of Maersk Inspirer, and Maersk Drilling Holdings Singapore Pte. Ltd.  The recoverable amount is determined based on the higher of its value-in-use or fair value less cost to sell. Given the continued illiquidity of the secondary market for offshore rigs with no supportable price indications management applies value-in-use calculations in the impairment test. The value-in-use is calculated based on cash flow projections in financial budgets and business plans for the coming 5 years as approved by management. For the period after the 5-year forecast period an expected inflation rate of 2.5% p.a. is applied. In nature, these cash flow projections are subject to judgement and estimates that are uncertain.  The assessment of indications of impairment of property, plant and equipment is based on the expectations for future profitability, contract coverage, etc applicable as of 31 December 2021, which may be different from the expectations for future profitability, contract coverage, etc applicable as of the approval of this annual report as set out in the Outlook section of the Management’s review. As a result, the Company may face adjustments to the recognized impairment of property, plant and equipment in future reporting periods.</c:DisclosureOfAnyUncertaintyConnectedWithRecognitionOrMeasurement><c:DisclosureOfRevenue contextRef="c405">USD'000
