Example. We all know there are 16045 winners (not including family members) from Asia. However, on CEAC Asian winner's numbers go only up to number 10700 or so, then numbers stop. Obviously, you cannot fit 16045 winners into 10700 numbers. So, about 9K winners are notified they are winners (among those 10700 numbers) and the rest 7K winners are not notified and do not know they are winners. Those 7K out of 16K are hidden winners. They are included into official reports as winners, but cannot participate in further processing until second batch of open winners is released (from those hidden winners)
