In case you are serious about not getting it: you can operate at a loss in a number of situations: if you have profits in reserve, if you have available credit to float the difference in revenue, or a combination therein. You cannot bleed forever, only as long as you have capital to push onward. If you have access to a ton of credit, or have a ton of money in the bank, you can take losses for quite some time. I haven't looked too deeply at their internals, but some companies choose to (properly) mark down existing assets or investments on their books to current market value at certain times for strategic tax purposes. Eg. if you have a warehouse full of stuff you can't sell, but profit from other divisions the right thing to do is to write down those assets to market value (sometimes that is zero, but not always)
