You've neatly summarized the REVO investment mess, goodboy. weak DD and poor assumptions make bad investment decisions. .. I couldn't agree more. Investment decisions based on 'unreliable' accounts and statements are bad investment decisions. Accepting 'unreliable' accounts and statements at face value is weak DD. REVO directors have admitted that they provided 'unreliable' accounts and public statements to investors. The result is that REVO is now shown to be a worthless stock. Simple.
