> Why else would they choose to have equity vest quarterly instead of with each pay period? This makes sense for reduced paperwork if the company is buying back 28% of the shares to pay taxes instead of selling it to the market to pay the taxes - the company can reduce the open market sale on vesting days, but keep it as a single event within the quarter (advance tax payment per quarter).
