Bailout 2: Book value발음듣기

In the last video I just discussed a personal balance sheet and what illiquidity or what insolvency means.발음듣기

And if you understood that, I think we're now ready to tackle what a balance sheet of some of these potentially troubled banks might look like.발음듣기

And I'm not going to go into the details.발음듣기

But I'm going to give you the big picture and I think that's essentially what matters.발음듣기

So essentially, these banks have a bunch of assets.발음듣기

And I'm going to talk about banks very generally right now, both commercial and investment banks.발음듣기

In a future video I'll tell you the difference between the two and what regulation means and what leverage means and all that.발음듣기

Maybe I'll touch on that in this video.발음듣기

But let's just kind of think about a generic balance sheet for a bank.발음듣기

So its assets.발음듣기

I'm just going to make up some things.발음듣기

Let's say that it has $1 billion in government bonds, U.S. government bonds.발음듣기

I'm just throwing that in there just as filler just to show you that there could be a lot of different types of assets in there.발음듣기

Let's say that it has another $10 billion in AAA corporate bonds.발음듣기

So you know these are loans to really solvent or very creditworthy companies.발음듣기

Companies that have really good cash flows.발음듣기

There's very little chance of them defaulting on their loans.발음듣기

And what is a bond?발음듣기

A bond is just a loan to another entity.발음듣기

If you loan me money, I could give you an IOU saying that Sal owes you $10.발음듣기

And that IOU, you could call that a Sal bond.발음듣기

So $1 billion of government bonds, that's an asset that says the government owes me a billion dollars.발음듣기

And in the meantime, it's going to pay me interest.발음듣기

Similarly, corporate bonds, that's saying that these corporations, wherever these bonds are issued by, they owe me collectively $10 billion and in the meantime they're going to pay me interest. So that's all it is.발음듣기

And all an asset is, is something that has some future economic value.발음듣기

And that's what these are.발음듣기

These bonds have some future economic value.발음듣기

They have the value of the interest payments.발음듣기

Plus eventually, they're going to pay you the $10 billion back.발음듣기

Or maybe it's something less than that.발음듣기

So the $10 is the interest payments plus what they're going to pay you back, which might be $9.9 billion.발음듣기

I'm making up numbers.발음듣기

But that's not the issue here.발음듣기

The crux of the issue is that there's this stinky asset here.발음듣기

Actually, let me draw a couple more assets here just to show you this is the stinkiest of them all.발음듣기

So let's say I have another group of assets.발음듣기

Let's say it's $10 billion of commercial mortgages.발음듣기

So this is, essentially, I lend money to companies to buy land or develop land or buy buildings that they're going to go rent out to other people.발음듣기

So once again, it's just a loan to someone else.발음듣기

And a loan to someone else that I've given is an asset.발음듣기

Because they owe me interest and eventually they're going to pay the money back to me.발음듣기

And then finally, and I'm not being comprehensive here, I'm going to throw in the crux of the issue here.발음듣기

Let me see, I have 21 right now, let me just make it an even number.발음듣기

Let's say that I have $4 billion, so it all adds up to 25.발음듣기

I have $4 billion in residential CDOs, collateralized debt obligations.발음듣기

And I've done a video on CDOs, but just to kind of have review, CDOs are a derivative instrument.발음듣기

I know that sounds complicated, but that just means they are derived from another instrument.발음듣기

Which probably is a sign that the stink is starting to emerge from this part of the balance sheet.발음듣기

What does it mean, derivative?발음듣기

Well, you take a bunch of mortgages.발음듣기

So I'll just draw it down here.발음듣기

These are house mortgages.발음듣기

Maybe you take a million of them.발음듣기

You group them all together.발음듣기

And you end up with a mortgage backed security.발음듣기

All a mortgage backed security is a loan to a big group of people and you put them all together so that you can kind of be able to statistically give it properties.발음듣기

Because if you lend to any one person, that's hard to trade.발음듣기

If you lend to a bunch of people, it starts to become something that you could trade with other people.발음듣기

Because they can understand it.발음듣기

And in aggregate, you could say 8% of people are going to default and all of that.발음듣기

But anyway, this isn't the crux of it either.발음듣기

I have a whole video on mortgage backed securities.발음듣기

CDOs, collateralized debt obligations, are derived from mortgage backed securities.발음듣기

And that's why they are called derivative instruments.발음듣기

What CDOs are, you take these mortgage backed securities, they're loans to some people in some region of the country, or maybe they're diversified across regions, then you slice and dice them.발음듣기

So what you do is, you slice them and into tranches.발음듣기

And I go into a lot more detail on this in the other videos.발음듣기

And you say, this group of the CDOs, they'll get the first payments.발음듣기

So any payments immediately go to this very senior tranche.발음듣기

And then the next payments go to this one.발음듣기

And then this top tranche, you could call it the most junior tranche, it's sometimes called the equity tranche.발음듣기

This tranche, they're going to get whatever is left over.발음듣기

So if everyone pays, they get made whole, but if a lot of people default, all the defaults are going to hit this tranche.발음듣기

And to kind of make up for the fact that this is the riskiest tranche, or essentially these people are taking on all of the risk, or essentially these tranches are giving all the risk to this tranche.발음듣기

And a tranche is just a layer, just a slice.발음듣기

I don't want to use too fancy words.발음듣기

But in return for taking on all of the risk, this person is going to get a higher yield.발음듣기

So while this person might be getting 6%, this person might be getting 7% on their money, maybe this person gets 12% on their money.발음듣기

This is another interesting thing.발음듣기

Because this person is the most secure, the ratings agency, which I'll probably do another whole series of videos on.발음듣기

They might give it a AAA rating.발음듣기

And maybe they give this tranche, and I'm making up things, but maybe they give it a AA rating.발음듣기

But this equity tranche, it will get a junkier rating.발음듣기

And because it's a junkier rating, no one is going to want to buy it.발음듣기

So the person who constructed this whole collateralized debt obligation and who sold these tranches to the public markets.발음듣기

And this process by the way is called securitization, because you're creating securities out of these assets that you sell to everyone, maybe the Chinese, or whoever, sovereign wealth funds.발음듣기

But people only want to buy these tranches.발음듣기

So the banks have to figure out what to do with this tranche, which is the stinky equity tranche.발음듣기

So most of them just kept it on their balance sheet.발음듣기

They said, oh it looks like housing never goes down, we get a really high yield on this, so we are going to keep this tranche for ourselves.발음듣기

And that's what these residential CDOs are, that are the crux of the issue.발음듣기

But anyway, that was just an aside.발음듣기

And so I wanted to show you this because these aren't just any residential CDOs.발음듣기

These aren't the AAAs.발음듣기

They might be, some of them.발음듣기

But just for the sake of argument, let's say that these are junky ones or smelly.발음듣기

So anyway, that's my example bank, the asset side of its balance sheet.발음듣기

Let's think about its liabilities.발음듣기

Well let's just say it has a bunch of loans.발음듣기

So let's say it has loan A for $10 billion.발음듣기

Let me actually throw some cash in here.발음듣기

Let's say it has a billion dollars of cash.발음듣기

A bank always has to keep some cash.발음듣기

Just in case someone asks for their money immediately.발음듣기

That's in the context of a commercial back.발음듣기

But anyway, let's say it has some cash just for immediate liquidity needs.발음듣기

So the liability side has loan A.발음듣기

It owes someone $10 billion.발음듣기

It has loan B, it's another $10 billion.발음듣기

And let's say it has loan C.발음듣기

Loan C is, just to make it interesting, let's say it's for $3 billion.발음듣기

So in this example right now, if we assumed that all of these asset values are correct and all of these liability values are correct, what is this bank's equity?발음듣기

And in this case, it's a publicly traded company, what is its shareholders' equity?발음듣기

Let's figure it out.발음듣기

Well, its assets are $21, $25, $26 billion in assets.발음듣기

Its liabilities are $23 billion.발음듣기

So $26 billion of assets minus $23 billion of liabilities means that we have $3 billion of equity, of shareholders' equity.발음듣기

And just to make it clear what this equity is.발음듣기

Let's say this is a publicly traded company.발음듣기

If you own a share of the company, you own a share of this equity.발음듣기

Actually, let's just write it out.발음듣기

Let's call this Wachovia Bank.발음듣기

Actually, I shouldn't, that's too close.발음듣기

Let's call this Bank A.발음듣기

And let's say that Bank A has, let me make up something, let's say that it has 500 million shares.발음듣기

If go into Yahoo Finance, you said how many shares are outstanding?발음듣기

It has 500 million shares.발음듣기

So, each share price, or the book value of each share price, essentially should be this $3 billion of equity based on the balance sheet.발음듣기

And that's why they call it book equity.발음듣기

Because the balance sheet is often called the company's books.발음듣기

So this is this $3 billion of equity divided by the number of shares.발음듣기

So each share should be worth, let's see, $3 billion divided by 500 million, it should be $6 of book equity per share.발음듣기

And that's something important to realize.발음듣기

Because a lot of people think that if a stock price goes to zero, that means that you're getting the company for nothing.발음듣기

No, that's not true.발음듣기

That just means that the equity is worth zero.발음듣기

And I just realized that I'm out of time.발음듣기

I'm going to continue this in the next video.발음듣기

And we'll explore this a little bit more.발음듣기

See you soon.발음듣기
