RE: You gotta love BWNFrom Pinetree's website - Disclosure Criteria
We disclose on our website only those investments which have already been disclosed to the public through either a press release, a regulatory filing or in our interim or annual financial statements, and only if the Fair Value of the investment is at least $500,000
Any investment in which we have a partially diluted ownership interest of at least 5%.
So it's safe to assume they own at least 5% of the outstanding shares of BWN, not including warrants.
