Pretty simple: not talking about a company buyback. The question was "why don't the officers buy stock on their own?"
Because Staelin owns ZERO SHARES and Kelly owns only 38 million shares. Nalepka owns 100 million that he was awarded. The FB user wanted to know why they weren't buying common stock at these supposed once-in-a-lifetime never-to-be-seen-again rock-bottom prices.
Kelly answered "I personally have enough money invested in convertible notes."
That's her excuse for not buying common stock with her own money to show confidence in her company. Obviously, she plans to convert those loans, not have the company pay them off. Because if she planned to have the company pay off those loans in the future, this excuse for not buying stock would make no sense.
