Otobai Company in Osaka, Japan is considering the introduction of an electrically powered motor scooter for city use. The scooter project requires an initial investment of 15 billion. The cost of capital is 10%. The initial investment can be depreciated on a straight-line basis over the 10-year life of the project. Profits are taxed at a rate of 50%.

Consider the following project estimates:

Market size	1.1 million
Market share		.1
Unit price		400,000
Unit variable cost		360,000
Fixed cost		2 billion

What is the NPV of the electric scooter project? (A negative amount should be indicated by a minus sign. Do not round intermediate calculations. Enter your answer in billions rounded to 3 decimal places.)
