Berthold was always was involved in RD, working to develop products and technology to bring to the market
And the results were no sales and no revenues, which resulted in a declining sp throughout his tenure and shareholder's money lost until he gave up and sold out.
If all he was interested in was R & D, he should have gotten a job at North Carolina State University instead of living off the shareholder's dime.
Bottom line is that shareholders are no better or worse off now as they were back then. Same play, different actors.
