This funding should be based primarily on a simple head count.
To make the site at Dormagen competitive, AKF will slash the 280 employe head count down to about 170.
The current head count for deaths by gunshot wounds this year in Los Angeles is in excess of six hundred people.
In that case, you should write everyone an individual note (unless total head-count's over ten!).
Note that banquet halls may require you to use their catering services and charge a minimum amount of money, no matter the head count.
