Then we have a balance sheet at the end of the year, so we've got one at the beginning of 2015, at the end of 2015. The difference in the retained earnings is going to be explained in the income statement for the year end at December 31, 2015. And the difference in cash, is going to be explained in the statement of cash flows for the year ended December 31, 2015. >> Here you go again with the difference between income and cash. Remind me, why are they different?

>> Okay, let's go back to the house example. So, let's say on your first balance sheet at the beginning of the year you have a $500,000 house, which is your asset, $450,000 mortgage which is your liability, and $50,000 of equity. Now let's say that during the year the value of your house increases to a $1 million, now you can't actually do this in practice, but for the sake of the example, let's assume you could write up the value of the house from 500,000 to a million at the end of the year. So, your balance sheet at the end of the year would have a million dollar asset, the house, 450,000 of liabilities because the mortgage doesn't change, but your equity would go up from 50,000 to 550,000. Now, if you look at the statement that explains the changes in two balance sheets. None of this affects the cash flow statement because there's no cash impact of your house going up in value. In fact, your cash up should probably went down as you were paying the mortgage. But your income statement would show a gain of $500,000 from the increase in your equity due to your ownership claim of the house.
