If you search for PLI bonus on the internal website you'll see that as stated by @ below the mid-year bonus is paid out to G12 and below unless the employee was not employed in the right time frames during the 1H or on an improvement plan. If the company is on target then you get 50% of your bonus with a PF of 1.0. If not, it is the discretion of the CEO/CFO to pay a smaller portion
I received my bonus today (US) without ever receiving a webletter so if you are in locations that are paid later I would not take it as a sign that you aren't getting your bonus.
