Janine Olivier owns and runs a popular restaurant in London. The kitchen is well-equipped but has only basic defences against the risk of fire. Currently, Janine's insurers charge rates of.004 to cover the restaurant building itself and .001 to cover consequential losses. The values at risk are 1,000,000 for the restaurant building and E600,000 for consequential losses. A contractor has offered to install a modern, automatic fire suppression system in the restaurant's kitchen for 7,200 (installation cost) and 2,000 for annual maintenance. The fire suppression system, if installed, would last 10 years and have zero scrap value at the end of that period. Janine's insurers advise her that, if she does install the fire suppression system in the kitchen, they would reduce the insurance premium for her restaurant by charging lower rates of only.00125 to cover risks to the building itself and.0005 to cover potential consequential losses. REQUIRED (making any necessary assumptions and showing ALL calculations): On the basis of the information provided, use a 10% discount rate to determine whether or not it would be worthwhile for Janine to have the new fire suppression system installed. a) (30 marks) Describe any variables OTHER than those used for your calculations in part a) of this question which could be relevant to the situation AND explain their implications for whether or not Janine should have the new fire suppression system installed b) (20 marks)
