Segment Information
Lexicon operates as a single reportable segment, primarily focusing on the discovery, development and commercialization of pharmaceutical products for the treatment of human disease. Substantially all of the Company’s revenues have been derived from drug discovery alliances, target validation collaborations for the development and, in some cases, analysis of the physiological effects of genes altered in knockout mice, technology licenses, subscriptions to its databases, product sales, government grants and contracts and compound library sales, as well as from commercial sales of its approved drug product.
The chief operating decision maker (“CODM”) is the Company’s chief executive officer (“CEO”). The CEO manages and allocates resources on a total company basis by assessing the overall level of resources available and how to best deploy these resources across research and development projects in line with the Company’s long-term company-wide strategic goals.
The CEO evaluates single-segment consolidated financial information against budget for purposes of making operating decisions, planning and forecasting for future periods, and deciding the level of investment in the Company’s various operating activities and other capital allocation activities. The CODM assesses financial performance based on consolidated net income (loss) (as reported on the consolidated statement of comprehensive loss). The CEO also uses consolidated cash and cash equivalents and short-term investments (which can be found on our Consolidated Balance Sheets) as a measure of segment assets for allocating resources.
