>> Okay, so let's talk about what happened during the financial crisis of 2007, 2008 and 2009. There were banks out there that had assets called mortgaged-backed securities. These are assets because they're claims on collecting cash payments from people that took out sub-prime mortgages. So let's say a bank had 10 billion of these mortgage-backed securities as assets. And let's say they had 9.5 billion of liabilities. And half a billion of equity. Financial crisis hits, these home owners no longer make their mortgage payments. Which means, these assets drop in value. So now they have to be written down in value from 10 billion to, let's say 1 billion. Now the liabilities don't change. In fact, that's why you need a government bailout because you're liabilities don't change. But what does change is the equity. The equity drops by 9 billion as well. And so it's another example where there's no cash flow impact of the change in these two balance sheets, but we end up showing a $9 billion loss on our income statement due to the drop in our equity claims on those assets.

Of course, we also have to mention the statement of stockholders' equity, which explains the changes in stockholders' equity between two balance sheets, which we will talk about more later in the course.
