Jiani is a vintner, and is deciding when to release a vintage of Pinot Noir.  If it is bottled and released now, the wine will be worth $1.2 million. If it is barrel-aged for a further year, it will be worth 20% more, though there will be additional costs of $200 000. If the interest rate is 7%, what is the difference in the benefit Jiani will realise if she releases the wine after barrel-aging it for one year or if he releases the wine now?
