Everyone knows the preferred buyer is Baker Brothers, so there’s no anonymity.
It was a bad decision by TRIL, IMO, to allow such shenanigans to go on. The 61-day notice period in the preferred registration (thanks for the citation) is a clear violation of the intent, albeit not the letter, of SEC regulations concerning Form-13G filing requirements. At a time when TRIL ought to be making its case to a wider group of small and medium-sized investors, it has instead acquiesced to the wishes of a large shareholder using a gimmick to circumvent SEC regulations.
