Note 15: Commitments and Contingencies We have entered into certain arrangements with developers whereby we have committed to purchase vacation ownership units at a future date to be marketed and sold under our Hilton Grand Vacations brand. As of September 30, 2017, we were committed to purchase approximately $208 million of inventory and land over a period of five years. The ultimate 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 nine months ended September 30, 2017 and 2016, we purchased $9 million and $11 million, respectively, of VOI inventory as required under our commitments. As of September 30, 2017, our remaining obligation pursuant to these arrangements was expected to be incurred as follows: $3 million in 2018, $187 million in 2019, $9 million in 2020, and $9 million in 2021. We are involved in litigation arising from the normal course of business, some of which includes claims for substantial sums. Management has also identified certain other legal matters where we believe an unfavorable outcome is reasonably possible and/or for which no estimate of possible losses can be made. While the ultimate results of claims and litigation cannot be predicted with certainty, we expect that the ultimate resolution of all pending or threatened claims and litigation as of September 30, 2017, will not have a material effect on our condensed consolidated results of operations, financial position or cash flows.
