We are engaged in selling products and services through various channels stemming from our retail, wholesale, and e-Commerce operations located throughout the U.S., Canada and Europe. We define our segments as those operations whose results our CODMs regularly review to analyze performance and allocate resources. Therefore, segment information is prepared on the same basis that management reviews financial information for operational decision-making purposes.

The reportable segments identified are our business activities for which discrete financial information is available and for which operating results are regularly reviewed by our CODMs. Beginning with the quarter ended March 31, 2019, we had a change in reportable segments due to the Canadian operations becoming a significant part of the business. We had an additional change in reportable segments beginning with the quarter ended September 30, 2019 due to the acquisition of our Netherlands subsidiary, at which time we established our European segment. As of December 31, 2019, we determined that we had three reportable segments based on the geographical areas where we conduct our business: (1) U.S., (2) Canada, and (3) Europe. The U.S. operating segment is comprised of our U.S. operations, the Canadian operating segment is comprised of our Canadian operations, and the European operating segment is comprised of our European operations, currently based in the Netherlands. Corporate and other activities which are not allocated to our reportable segments consist primarily of equity-based compensation expenses, unrealized gains on equity securities, and other corporate overhead items. Assets related to our corporate headquarters as well as our cash proceeds from the IPO are not allocated to any of our reportable segments. We sell similar individual products and services in each of our segments.

The table below provides information on revenues from external customers, intersegment revenues, segment operating income (loss), and depreciation and amortization by reportable segment for the years ended December 31, 2019 and 2018. We eliminate intersegment revenues in consolidation.
