Description of changes in reporting goodwill and intangible assets in segment assets	During fiscal 2019, we elected to no longer include goodwill and intangible assets in segment assets, as these assets are not used by the CODM to evaluate the respective segment’s operating performance, to allocate resources to the individual segments, or to determine executive compensation.

- Definition

Number of operating segments. An operating segment is a component of an enterprise: (a) that engages in business activities from which it may earn revenues and incur expenses (including revenues and expenses relating to transactions with other components of the same enterprise), (b) whose operating results are regularly reviewed by the enterprise's chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance, and (c) for which discrete financial information is available. An operating segment may engage in business activities for which it has yet to earn revenues, for example, start-up operations may be operating segments before earning revenues.
