Many of the Balancer Labs contributors/employees are leaving to start their own SPs for the Balancer foundation. Because of that, BLabs just returned to the multisig DAO the BAL that was earmarked for them as token incentives plus what was planned for new hires in the areas that BLabs is no longer going to be active in (marketing, bizdev, frontend etc).
The DAO can choose to use these tokens as it pleases, I just wanted to give the context for this return of BAL to the DAO.
