ARO, a company that owns and operates offshore drilling rigs in Saudi Arabia, was formed and commenced operations in 2017 pursuant to the terms of an agreement entered into by Rowan Companies Limited (formerly Rowan Companies plc) ("Rowan") and Saudi Aramco to create a 50/50 joint venture ("Shareholder Agreement"). Pursuant to our completion of the combination with Rowan (the "Rowan Transaction") on April 11, 2019 (the "Transaction Date"), we acquired Rowan's interest in ARO making us a 50% partner. As of September 30, 2021, ARO owns seven jackup rigs, has ordered two newbuild jackup rigs, and leases eight rigs from us through bareboat charter arrangements (the "Lease Agreements") whereby substantially all operating costs are incurred by ARO. All of the leased rigs were operating under three-year drilling contracts with Saudi Aramco. The seven rigs owned by ARO, previously purchased from Rowan and Saudi Aramco, are currently operating under contracts with Saudi Aramco for an aggregate 15 years provided that the rigs meet the technical and operational requirements of Saudi Aramco.

The Company and Saudi Aramco have agreed to take all steps necessary to ensure that ARO purchases 20 newbuild jackup rigs over an approximate 10-year period. In January 2020, ARO ordered the first two newbuild jackups, each with a shipyard price of $176.0 million, for delivery scheduled in 2022. The joint venture partners intend for the newbuild jackup rigs to be financed out of available cash from ARO's operations and/or funds available from third-party debt financing. In the event ARO has insufficient cash from operations or is unable to

obtain third-party financing, each partner may periodically be required to make additional capital contributions to ARO, up to a maximum aggregate contribution of $1.25 billion from each partner to fund the newbuild program. Each partner's commitment shall be reduced by the actual cost of each newbuild rig, on a proportionate basis. The joint venture partners agreed that Saudi Aramco, as a customer, will provide drilling contracts to ARO in connection with the acquisition of the newbuild rigs. The initial contracts provided by Saudi Aramco for each of the newbuild rigs will be for an eight-year term. The day rate for the initial contracts for each newbuild rig will be determined using a pricing mechanism that targets a six-year payback period for construction costs on an EBITDA basis. The initial eight-year contracts will be followed by a minimum of another eight years of term, re-priced in three-year intervals based on a market pricing mechanism.

Upon establishment of ARO, Rowan entered into (1) an agreement to provide certain back-office services for a period of time until ARO develops its own infrastructure (the "Transition Services Agreement"), and (2) an agreement to provide certain Rowan employees through secondment arrangements to assist with various onshore and offshore services for the benefit of ARO (the "Secondment Agreement"). These agreements remained in place subsequent to the Rowan Transaction. Pursuant to these agreements, we or our seconded employees provided various services to ARO, and in return, ARO provided remuneration for those services. During the quarter ended June 30, 2020, almost all remaining employees seconded to ARO became employees of ARO. Additionally, our services to ARO under the Transition Services Agreement were completed as of December 31, 2020.

Contract drilling expense is inclusive of the bareboat charter fees for the rigs leased from us. Cost incurred under the Secondment Agreement are included in contract drilling expense and general and administrative, depending on the function to which the seconded employee's service related. Substantially all costs incurred under the Transition Services Agreement are included in general and administrative. See additional discussion below regarding these related-party transactions.

We account for our interest in ARO using the equity method of accounting and only recognize our portion of ARO's net income, adjusted for basis differences as discussed below, which is included in equity in earnings (losses) of ARO in our Condensed Consolidated Statements of Operations. ARO is a variable interest entity; however, we are not the primary beneficiary and therefore do not consolidate ARO. Judgments regarding our level of influence over ARO included considering key factors such as each partner's ownership interest, representation on the board of managers of ARO and ability to direct activities that most significantly impact ARO's economic performance, including the ability to influence policy-making decisions. Our investment in ARO would be assessed for impairment if there were changes in facts and circumstances that indicate a loss in value may have occurred. If a loss were deemed to have occurred and this loss was determined to be other than temporary, the carrying value of our investment would be written down to fair value and an impairment recorded.

We have an equity method investment in ARO that was recorded at its estimated fair value as of the date we acquired our 50% interest on April 11, 2019 ("Investment Date"). We computed the difference between the fair value of ARO's net assets and the carrying value of those net assets in ARO's U.S. GAAP financial statements ("basis differences") on that date. These basis differences primarily relate to ARO's long-lived assets and the recognition of intangible assets associated with certain of ARO's drilling contracts that were determined to have favorable terms. Additionally, in fresh start accounting, we have recorded our investment in ARO at its estimated fair value as of the date of emergence. Basis differences on that date primarily related to ARO's long-lived assets.

Basis differences are amortized over the remaining life of the assets or liabilities to which they relate and are recognized as an adjustment to the equity in earnings (losses) of ARO in our Condensed Consolidated Statements of Operations. The amortization of those basis differences are combined with our 50% interest in ARO's net income. A reconciliation of those components is presented below (in millions):

Amounts receivable from ARO related to the items above totaled $6.5 million and $21.6 million as of September 30, 2021 (Successor) and December 31, 2020 (Predecessor), respectively, and are included in accounts receivable, net, on our Condensed Consolidated Balance Sheets.

We had $28.5 million and $30.9 million of Contract Liabilities related to the Lease Agreements as of September 30, 2021 (Successor) and December 31, 2020 (Predecessor), respectively. Accounts payable to ARO totaled $14.8 million as of September 30, 2021 (Successor). There were no accounts payable to ARO as of December 31, 2020 (Predecessor). Contract liabilities related to the Lease Agreements are subject to adjustment during the lease term. The per day bareboat charter amount in the Lease Agreements is subject to adjustment based on actual performance of the respective rig.

During 2017 and 2018, Rowan contributed cash to ARO in exchange for 10-year shareholder notes receivable at a stated interest rate of LIBOR plus two percent. As of September 30, 2021 (Successor) and December 31, 2020 (Predecessor), the carrying amount of the long-term notes receivable from ARO was $241.3 million and $442.7 million, respectively. The notes receivable were adjusted to fair value as of the emergence date. The discount to the principal amount of $442.7 million will be amortized using the effective interest method to interest

income over the remaining terms of the notes. The Shareholders’ Agreement prohibits the sale or transfer of the shareholder note to a third party, except in certain limited circumstances. The notes receivable may be reduced by future Company obligations to the joint venture. Interest is recognized as interest income in our Condensed Consolidated Statement of Operations. For the Successor, during the three and five months ended September 30, 2021, interest totaled $2.7 million and $4.4 million, respectively. For the Predecessor, the four months ended April 30, 2021, interest totaled $3.5 million. Interest totaled $4.5 million and $13.7 million for the three and nine months ended September 30, 2020, respectively. As of September 30, 2021 (Successor), our interest receivable from ARO was $7.9 million, which is included in Accounts receivable, net, on our Condensed Consolidated Balance Sheet. There was no interest receivable from ARO as of December 31, 2020 (Predecessor).

The following table summarizes the total assets and liabilities as reflected in our Condensed Consolidated Balance Sheets as well as our maximum exposure to loss related to ARO (in millions). Our maximum exposure to loss is limited to (1) our equity investment in ARO; (2) the carrying amount of our shareholder notes receivable; and (3) other receivables and contract assets related to services provided to ARO, partially offset by contract liabilities as well as payables for services received.
