Analyse the following scenarios and recommend what type of company should be adopted:

Bob would like to form a company with his two brothers to manufacture widgets.

Chris would like to form a company to manufacture toys. However, he does not want his employees, friends or family to know how well the company is doing.

David is a founder member of a local charity. The charity would like to set up a shop which can be used to sell locally made goods. Any profits made by the shop will be ploughed back into the charity. The bank is happy to lend $100 000 to get the shop started but has asked for some security.
