Good footnote catch. Now I had to go back and double check that he actually DID buy the 8MM shares. He did. At $1.43.
What's interesting to me is that Tkachev still lists his home address as Moscow! My confirmation bias is running wild here. ;-) Now, boys and girls, it's time to confabulate what possible "consulting services" could Tkachev be performing in Russia for a Houston oil company? Might those services involve chatting up people in power in Russia? How about BP where he supposedly worked for many years?
