Blackrock Ownership
Morningstar has to have a typo, as there aren't even that many preferred shares. Here is an excerpt from an email response from IR (Naomi) to me on January 6th, 2015.
The corporate structure is as follows (from the Q3 MD&A):
252,100,672 common shares
15,807,349 options
63,000,000 convertible preferred shares (owned by Blackrock, Banro’s largest stakeholder)
116,000 preferred shares – Series A
