Investing is often described as the process of laying out money now in the expectation of receiving more money in the future. At Berkshire Hathaway we take a more demanding approach, defining investing as the transfer to others of purchasing power now with the reasoned expectation of receiving more purchasing power — after taxes have been paid on nominal gains — in the future. More succinctly, investing is forgoing consumption now in order to have the ability to consume more at a later date.
