The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is regularly evaluated by the chief operating decision makers (“CODMs”), which are the Company’s chief executive officer and chief operating officer, in deciding how to allocate resources and assess performance. The Company’s CODMs evaluate the Company’s financial information and resources and assess the performance of these resources on a consolidated basis. Since the Company operates in one operating segment, all required financial segment information can be found in the consolidated financial statements.
