Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Tax Matter Beginning in the third quarter of 2023 and continuing through the first quarter of 2024, the Company has received cumulative assessments of approximately $95 million from His Majesty’s Revenue and Customs (“HMRC”) for unpaid value added tax (“VAT”) related to certain clear aligner sales made during the period of October 2019 through May 2023. We are required to pay these assessments prior to contesting or litigating in statutory appeal. The Company has historically asserted and continues to assert that doctor prescribed clear aligners sold by dentists for the orthodontic treatment of patient malocclusions are exempt from VAT, that the Company has reasonably relied upon statements and guidance by HMRC and that the Company’s interpretation of United Kingdom legislation is appropriate. A hearing has been scheduled for October 9 through October 10, 2024 regarding the unpaid VAT related to certain aligner sales made during the period of October 2019 through May 2023. It is not possible at this stage to accurately evaluate the likelihood of an unfavorable outcome of any legal challenges brought by the Company against HMRC disputing this initial assessment and any assessments for other past periods. Accordingly, the Company has determined that a potential loss related to unpaid VAT is not probable. As such, we have not recorded a contingent loss for these assessments in our Condensed Consolidated Statements of Operations for the six months ended June 30, 2024. The Company acknowledges that this matter poses risks of litigation and the ultimate resolution of this matter could result in an unfavorable ruling, which consequently could lead to a significant loss to the Company. As of June 30, 2024, if an unfavorable ruling is issued, we estimate a potential exposure of approximately $115 million, depending on fluctuations of foreign currency exchange rates, excluding interest and penalties. Indemnification Provisions In the normal course of business to facilitate transactions in our services and products, we indemnify certain parties: customers, vendors, lessors, and other parties with respect to certain matters, including, but not limited to, services to be provided by us and intellectual property infringement claims made by third parties. In addition, we have entered into indemnification agreements with our directors and our executive officers that will require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. Several of these agreements limit the time within which an indemnification claim can be made and the amount of the claim. It is not possible to make a reasonable estimate of the maximum potential amount of future payments, if any, under these indemnification agreements due to the unique facts and circumstances involved in each particular agreement. Additionally, we have a limited history of prior indemnification claims and the payments we have made under such agreements have not had a material adverse effect on our results of operations, cash flows or financial position. However, to the extent that valid indemnification claims arise in the future, future payments by us could be significant and could have a material adverse effect on our results of operations or cash flows in a particular period. As of June 30, 2024, we did not have any material indemnification claims that were probable or reasonably possible.
