Jim, if a company is private, then it can't be owned by a public company like RCCH. The way RCCH would own a company, what geno foolishly calls a "sole subsidiary" is by owning either 100% of the stock of that company.
In the alternative, RCCH could own a portion of a company. If RCCH owns greater than 50.1% of the company, than the sole subsidiary would be consolidated into RCCH's financials both balance sheet and income statement (i.e. it would show the revenues).
Anything less than 50% would be a minority stake and would show as an equity investment on the balance sheet, no revenues.
In order for RCCH to get cash from a minority stakes is through a divdend, which would show up on the financials.
Again, going back to the last fins filed, I saw neither.
