From my limited understanding of things: BHD NTA is currently made up of mostly (possibly all?) cash and it's currently trading at a significant discount to NTA. As one poster put it earlier - it's like buying $1 for 70 cents.
It's also a vote of confidence and a demonstration that their interests are aligned with the interests of shareholders. Remember that two of the directors previously held little to no BHD shares at all. Now they have skin in the game.
