The way BRL is buying suggests that they are targeting the 75 million shares to be bought over one full year. 

This is all wrong. 

Once the L&M Court case is decided, there is nothing they can do about the share price.  If we win, then the share price will hopefully go up.  If the court case goes against us, then I doubt anything will happen...a court ruling of US$60 million is already in the valuation.  Even if you add US$60 million to their Enterprise Value, you get a multiple of only 3 times cash flow (based on met coal futures strip going out 2 years).  Plus, the overhang is well known.  The market till then is going to be in a "sell the rumor" mode...it will turn into a "buy the news" mode.

What they should be doing is buying the remaining 61 million shares by June 30 2019.  Given that there are 118 trading  days between now and then, they should be buying at over 500,000 shares a day.  Right now, they are averaging 250,000 shares a day.
