Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Tax Matter During the three months ended September 30, 2023, the Company received a notice and initial assessment, in the amount of approximately $27 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 June 2022 through May 2023. We are required to pay this initial assessment prior to contesting or litigating the assessment in administrative and judicial proceedings. 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. However, 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, if any. 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 the initial assessment in our Condensed Consolidated Statements of Operations for the three or nine months ended September 30, 2023. 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 September 30, 2023, if an unfavorable ruling is issued, we estimate a potential exposure up to approximately $100 million, excluding interest and penalties. Off-Balance Sheet Arrangements As of September 30, 2023, we had no material off-balance sheet arrangements that have, or are reasonably likely to have, a current or future material effect on our consolidated financial condition, results of operations, liquidity, capital expenditures or capital resources other than certain items disclosed in Note 8 “Commitments and Contingencies” of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2022. 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 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 September 30, 2023, we did not have any material indemnification claims that were probable or reasonably possible.
