Barak Obama reportedly was paid $77 million (paid at the beginning of the first year) to write his post-White House memoir. Suppose the book took three years to write. In the time he spent writing, Obama could have been paid to make speeches. Given his popularity, assume that he could earn $10 million per year (paid at the end of the year) speaking instead of writing. Assume his cost of capital is 10% per year. Assume that, once the book is finished, it is expected to generate royalties of $5 million in the first year (paid at the end of the year) and these royalties are expected to decrease at a rate of 30% per year in perpetuity. What is the NPV of the book with the royalty payments? (in $ million, Round to one decimal place.)
