⁽³⁾ Utilizes the Russell 2000 Index, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Form 10-K for the year ended December 31, 2022. Because of the uniqueness of our markets and products and lack of publicly traded peers, we do not believe that a combination of peer issuers can be selected on an industry or line-of-business basis to provide a meaningful basis for comparing shareholder return. Accordingly, the Russell 2000 Index, which is comprised of issuers with generally similar market capitalizations to that of the Company, is included in the table as permitted by applicable regulations. The comparison assumes $100 was invested for the period starting December 31, 2019, through the end of the listed year in the Company and in the Russel 2000 Index, respectively. Historical stock performance is not necessarily indicative of future stock performance.
