A new marketing campaign will cost $1 million to produce in year 0. After the campaign is released, it is expected to generate $800,000 in profits in year 1, which will decrease by 50% each year until year 4. Profits from the campaign are shared with a partnering company, who will receive $50,000 each year for 4 years. If the MARR is 15%, what is the NPV of this campaign?
