We have entered into certain arrangements with developers whereby we have committed to purchase vacation ownership units or other real estate at a future date to be marketed and sold under our Hilton Grand Vacations brand. As of December 31, 2020, we were committed to purchase approximately $454 million of inventory and land over a period of 10 years and $20 million of other commitments under the normal course of business. Additionally, we have committed to develop additional vacation ownership units at an existing resort in Japan. During the second quarter of 2020, we entered into an agreement to exchange parcels of land in Hawaii, subject to the successful completion of zoning, land use requirements and other applicable regulatory requirements. The actual amount and timing of the acquisitions is subject to change pursuant to the terms of the respective arrangements, which could also allow for cancellation in certain circumstances. During the years ended December 31, 2020 and 2019, we purchased $23 million and $75 million, respectively, as required under our commitments. As of December 31, 2020, our remaining obligation pursuant to these arrangements was expected to be incurred as follows:

($ in millions)	2021		2022		2023		2024		2025		Thereafter		Total

We are involved in litigation arising from the normal course of business, some of which includes claims for substantial sums. Management has evaluated all legal matters and we believe that possible losses derived from an unfavorable outcome that is reasonably possible or remote is not reasonably estimable. While the actual results of claims and litigation cannot be predicted with certainty, we expect that the resolution of all pending or threatened claims and litigation as of December 31, 2020, will not materially affect our consolidated financial statements.
