Rent expense under operating leases totaled $1,369, $1,316 and $1,689 for the years ended December 31, 2021, 2020 and 2019, respectively, and is included in Selling, general, and administrative expense in the Consolidated Statements of Operations and Comprehensive (Loss) Income.

We are involved in various lawsuits, claims, inquiries, and other regulatory and compliance matters, most of which are routine to the nature of our business. When it is probable that a loss will be incurred and where a range of the loss can be reasonably estimated, the best estimate within the range is accrued. When the best estimate within the range cannot be determined, the low end of the range is accrued. The ultimate resolution of these claims could affect future results of operations should our exposure be materially different from our estimates or should liabilities be incurred that were not previously accrued. Potential insurance reimbursements are not offset against potential liabilities.

During 2018 Wright Medical Technology, Inc. (“Wright Medical”) sued the Company, claiming patent infringement targeting essentially all of our patents. The case was subsequently updated to include trade secret misappropriations. We have filed motions to dismiss all allegations. We currently believe that we have substantial and meritorious defenses to Wright Medical’s claims and intend to vigorously defend our position, including through the trial and appellate stages if necessary. As the case is ongoing, we are unable to determine the likelihood of an outcome or estimate a range of reasonably possible settlement, if any. Accordingly, we have not made an accrual for any possible loss. The outcome of any litigation, however, is inherently uncertain, and an adverse

judgment or settlement in the Wright Medical proceeding, if any, could materially and adversely affect our business, financial position and results of operations or cash flows. In addition to Wright Medical’s claims set forth above, we received in December 2021 an additional complaint from Wright Medical covering patents different than the Wright Asserted Patents. While the proceedings in connection with such complaint are in early stages, we do not at this time believe they represent a material liability to our company. We have incurred, and expect that we will continue to incur, significant expense in defending against the allegations made by Wright Medical.
