The Financial Times is considering introducing a new monthly magazine. The company anticipates that it will cost £20 million in initial costs to create the infrastructure needed to produce the magazine, and that it can depreciate this cost straight line over the next 10 years to a salvage value of £5 million. The Financial Times expects to price the magazine at £2 an issue on the newsstands and it expects advertising revenues of £1.50 per issue sold; the printing and production costs are expected to be £1 per issue. The magazine’s contents will be produced by the existing staff of the paper, but the Times will have to increase its total annual payroll cost, which is currently £20 million, by 10%. The cost of capital for the New York Times is 9% and it can be used for this investment as well. The corporate tax rate is 40%.

How many magazines will the Financial Times have to sell each month to break even (in terms of NPV) on this investment at the end of the next 10 years?
