(a) Whether the general criteria for revenue recognition have been met;

(b) The concept of a 'critical event' for revenues recognised all at once; and

(c) The proportionate recognition that is available for revenue earned over several accounting periods:
1. Coffee shop sales of coffee

2. Sales of housing subdivisions 3. Sales of natural gas to businesses and residences

4. Magazine subscription sales

5. Ticket sales for concerts
