If you're looking to invest in someone else's deal (also known as a syndicated deal), you might be looking at proformas and see the abbreviation AUD. What does AUD stand for? Assets Under Management. With respect to housing, this refers to the number of properties that a person is managing. For example, if I were a property manager for 10 houses that were each valued at $1 million each, then I'd have $10 million worth of Assets Under Management. The same idea works for stocks and other investments. For example, Warren Buffett, through his company Berkshire Hathaway, has several billions of dollars of Assets Under Management (the value of the stocks that his company controls).
