> Forgive me for my ignorance, but what determines the level of scrutiny that a publicly traded company has to make available, in terms of its sources of revenue? How far do they get broken down, either by law/regulation or by custom? Companies are only required to provide an aggregate financial statement. They are not required to provide a line-item breakdown. They're not even required to provide a breakdown by division, although companies usually supply that. There is no convention. Two different companies in the same industry may provide different breakdowns. Typically, companies provide the same breakdown that they have historically provided in the past. However, as they grow, they tend to roll things up into ever-larger chunks. So you lose some granularity.
