RVXoldtimer-

Thanks for pointing that out - you are absolutely correct - I wasn't sure if they had an obligation to distribute the RPS revenues - your querie prompted me to review the 10/31/15 MD&A on the Zenith website and this is what I found - 

With respect to recording the royalties:

"We will recognize a royalty receivable when royalties are reasonably determinable and the economic benefits are probable to flow to us."

Re: payments to shareholders:

"We hold royalty preferred shares of Resverlogix which entitle us to dividends based on a percentage of net Apo Revenue, if any, received by Resverlogix, its affiliates or licensees. The royalty preferred shares of Resverlogix that we hold represent a significant asset. However, there is no assurance that dividends will ever be paid in respect of the royalty preferred shares."

Presumably the initial RPS revenue stream would be used to fund Zenith activities - Nasdaq listing, R&D, etc.
