Collateralized Debt Obligation (CDO)

  • 0:01 - 0:02
    Welcome back.
  • 0:02 - 0:04
    Well, in the last presentation,
    we described a
  • 0:04 - 0:06
    situation where you had
    a bunch of borrowers.
  • 0:06 - 0:08
    They needed $1 billion
    collectively, because there's
  • 0:08 - 0:11
    1000 of them and they each
    needed $1 million
  • 0:11 - 0:13
    to buy their house.
  • 0:13 - 0:15
    And they borrowed the money
    essentially from a special
  • 0:15 - 0:16
    purpose entity.
  • 0:16 - 0:18
    They borrowed it from their
    local mortgage broker, who
  • 0:18 - 0:20
    then sold it to a bank, or to
    an investment bank, who
  • 0:20 - 0:23
    created the special purpose
    entity, and then they IPO the
  • 0:23 - 0:26
    special purpose entity and raise
    the money from people
  • 0:26 - 0:28
    who bought the mortgage-backed
    securities.
  • 0:28 - 0:30
    But essentially what happened
    is the investors in the
  • 0:30 - 0:32
    mortgage-backed securities
    provided the money to the
  • 0:32 - 0:33
    special purpose entity to
  • 0:33 - 0:35
    essentially loan to the borrowers.
  • 0:35 - 0:37
    And then the reason why we call
    it a security is because,
  • 0:37 - 0:40
    not only are these people
    getting this 10% a year, but
  • 0:40 - 0:42
    if they want to -- let's say
    that you had one of these
  • 0:42 - 0:44
    mortgage-backed securities and
    you paid $1000 for it.
  • 0:44 - 0:46
    And you're getting this 10%
    a year, but then all of a
  • 0:46 - 0:49
    sudden, you think that the whole
    mortgage industry is
  • 0:49 - 0:51
    about to collapse, a bunch of
    people are going to default,
  • 0:51 - 0:52
    and you want out.
  • 0:52 - 0:54
    If you just gave someone
    a loan, there'd be
  • 0:54 - 0:55
    no way to get out.
  • 0:55 - 0:57
    You'd have to sell that
    loan to someone else.
  • 0:57 - 0:58
    But if you have a
    mortgage-backed security, you
  • 0:58 - 1:00
    can actually trade the security
    with someone else.
  • 1:00 - 1:02
    And they might pay you, who
    knows, they might pay more
  • 1:02 - 1:03
    than $1000.
  • 1:03 - 1:03
    They might pay you less.
  • 1:03 - 1:06
    But there will be at least some
    type of a market in the
  • 1:06 - 1:08
    security, so you could have what
    you could call liquidity.
  • 1:08 - 1:11
    Liquidity just means that
    I have the security
  • 1:11 - 1:12
    and I can sell it.
  • 1:12 - 1:14
    I could trade it just like I
    could trade a share of IBM or
  • 1:14 - 1:18
    I could trade a share
    of Microsoft.
  • 1:18 - 1:21
    But like we said before, this
    security, in order to place a
  • 1:21 - 1:24
    value on it, you have to do some
    type of analysis of what
  • 1:24 - 1:25
    you think it's worth.
  • 1:25 - 1:31
    Or what you think the real
    interest will be after you
  • 1:31 - 1:34
    take into account people
    pre-paying their mortgage,
  • 1:34 - 1:35
    people defaulting on their
    mortgage, and other things
  • 1:35 - 1:38
    like short-term interest rates,
    et cetera, et cetera.
  • 1:38 - 1:40
    And there is only maybe a small
    group of people who are
  • 1:40 - 1:43
    sophisticated enough to be able
    to figure that out to
  • 1:43 - 1:45
    make some type of models and
    who knows if even they're
  • 1:45 - 1:47
    sophisticated enough.
  • 1:55 - 1:58
    There might be a whole other
    class of investors
  • 1:58 - 2:00
    here, say this guy.
  • 2:00 - 2:03
    He would love to kind of invest
    in insecurities, but he
  • 2:03 - 2:04
    thinks this is too risky.
  • 2:04 - 2:09
    He'd be willing to take a lower
    return as long as he was
  • 2:09 - 2:11
    allowed to invest in less
    risky investments.
  • 2:11 - 2:14
    Maybe by law, maybe he's a
    pension fund or he's some type
  • 2:14 - 2:16
    of a mutual fund, that's forced
    to invest in something
  • 2:16 - 2:18
    of a certain grade.
  • 2:18 - 2:26
    And say that there's another
    investor here, and he thinks
  • 2:26 - 2:27
    that this is boring.
  • 2:27 - 2:28
    You know, 9%, 10%.
  • 2:28 - 2:29
    Who cares about that?
  • 2:29 - 2:31
    He wants to see bigger
    and bigger returns.
  • 2:31 - 2:35
    So there's no way for him to
    invest in this security and to
  • 2:35 - 2:36
    get better returns.
  • 2:36 - 2:40
    So now we're going to take this
    mortgage-backed security
  • 2:40 - 2:45
    and introduce one step further
    kind of permutation or
  • 2:45 - 2:46
    derivative of what this is.
  • 2:46 - 2:47
    That's all derivatives are.
  • 2:47 - 2:49
    You've probably heard the term
    derivatives and people do a
  • 2:49 - 2:52
    lot of hand-waving saying, oh,
    it's a more complicated form
  • 2:52 - 2:53
    of security.
  • 2:53 - 2:57
    All derivative means is you take
    one type of asset and you
  • 2:57 - 3:00
    slice and dice it in a way to
    spread the risk, or whatever.
  • 3:00 - 3:02
    And so you create a
    derivative asset.
  • 3:02 - 3:04
    It's derived from the
    original asset.
  • 3:04 - 3:09
    So let's see how we could use
    this same asset pool, the same
  • 3:09 - 3:13
    pool of loans, and satisfy
    all of these people.
  • 3:13 - 3:16
    Satisfy this guy, who wants
    maybe a lower return but lower
  • 3:16 - 3:19
    risk, and this guy, who's
    willing to take a little bit
  • 3:19 - 3:21
    higher risk in exchange
    for higher return.
  • 3:24 - 3:27
    So now in this situation, we
    have the same borrowers.
  • 3:27 - 3:29
    They borrowed $1 billion
    collectively, right, because
  • 3:29 - 3:31
    there's 1000 of them, et
    cetera, et cetera.
  • 3:31 - 3:34
    And they're still a special
    purpose entity, but now,
  • 3:34 - 3:39
    instead of just slicing up the
    special purpose entity a
  • 3:39 - 3:43
    million ways, what we're going
    to do is we're going to split
  • 3:43 - 3:47
    it up first into three, what
    we could call, tranches.
  • 3:47 - 3:51
    A tranche is just a bucket,
    if you will, of the asset.
  • 3:51 - 3:53
    And we're going to call the
    three tranches: equity,
  • 3:53 - 3:56
    mezzanine, and senior.
  • 3:56 - 3:58
    These are the words
    that are commonly
  • 3:58 - 3:59
    used in this industry.
  • 3:59 - 4:05
    A senior just means, if this
    entity were to lose money,
  • 4:05 - 4:08
    these people get their money
    back first. So it's the least
  • 4:08 - 4:10
    risk out of all of
    the tranches.
  • 4:10 - 4:13
    Mezzanine, that just means
    the next level or middle.
  • 4:13 - 4:15
    And these guys are some
    place in between.
  • 4:15 - 4:19
    They have a little bit more
    risk, and they still get a
  • 4:19 - 4:21
    little bit more reward than
    senior, but they have less
  • 4:21 - 4:24
    risk than this equity tranche.
  • 4:24 - 4:24
    Equity tranche.
  • 4:24 - 4:27
    These are the people who
    first lose money.
  • 4:27 - 4:29
    Let's say some of these
    borrowers start defaulting.
  • 4:29 - 4:31
    It all comes out of the
    equity tranche.
  • 4:31 - 4:34
    So that's what protects the
    senior tranche and the
  • 4:34 - 4:36
    mezzanine tranche
    from defaults.
  • 4:36 - 4:39
    So in this situation what we did
    is we raised -- out of the
  • 4:39 - 4:43
    $1 billion we needed -- $400
    million from the senior
  • 4:43 - 4:46
    tranche, $300 million from the
    mezzanine tranche, and then
  • 4:46 - 4:48
    $300 million from the
    equity tranche.
  • 4:48 - 4:53
    The $400 million senior tranche
    we raised from soon.
  • 4:53 - 4:57
    1000 senior securities,
    collateralized debt
  • 4:57 - 4:57
    obligations.
  • 4:57 - 5:00
    These are these, right here.
  • 5:00 - 5:03
    Say there were 400,000 of these
    and these each cost
  • 5:03 - 5:08
    $1000, right?
  • 5:08 - 5:10
    Let's say these cost $1000.
  • 5:10 - 5:12
    And we issued 400,000
    of these.
  • 5:17 - 5:20
    So we raised $400 million.
  • 5:20 - 5:23
    Let's say we give these
    guys a 6% return.
  • 5:23 - 5:25
    And you might say, 6%,
    that's not much.
  • 5:25 - 5:30
    But these guys, it is pretty low
    risk, because in order for
  • 5:30 - 5:36
    them to not get their 6%, the
    value of this $1 billion asset
  • 5:36 - 5:39
    or these $1 billion loans, would
    have to go down below
  • 5:39 - 5:40
    $400 million.
  • 5:40 - 5:43
    Maybe I'll do a little bit more
    math in another example.
  • 5:43 - 5:45
    But I think it'll start
    making sense to you.
  • 5:45 - 5:48
    For example, every year we said
    there's going to be $100
  • 5:48 - 5:49
    million in payments, right?
  • 5:49 - 5:50
    Because it's 10%.
  • 5:50 - 5:52
    $100 million in payments.
  • 5:52 - 5:55
    Of that $100 million in
    payments, 6% on the $400
  • 5:55 - 5:58
    million, that's $24 million
    in payments.
  • 5:58 - 5:59
    Right?
  • 5:59 - 6:02
    So $24 million in payments will
    go to the senior tranche.
  • 6:02 - 6:07
    Similarly we issued 300,000
    shares at $1000 per share on
  • 6:07 - 6:08
    the mezzanine tranche.
  • 6:08 - 6:09
    This is also 1000.
  • 6:09 - 6:10
    This is the mezzanine tranche.
  • 6:10 - 6:14
    And let's say they get 7%,
    a slightly higher return.
  • 6:14 - 6:16
    And these percentages are
    usually determined by some
  • 6:16 - 6:18
    type of market or what people
    are willing to get.
  • 6:18 - 6:20
    But let's just say it's
    fixed for now.
  • 6:20 - 6:21
    Let's say it's 7%.
  • 6:21 - 6:24
    So 300,000 shares, seven 7%.
  • 6:24 - 6:26
    These guys are going
    to get $21 million.
  • 6:26 - 6:27
    Right?
  • 6:27 - 6:30
    So out of the $100 million every
    year, $24 million is
  • 6:30 - 6:33
    going to go to these guys, $21
    million is going to go to
  • 6:33 - 6:34
    these guys, and then whatever's
    left over is going
  • 6:34 - 6:37
    to go to the equity tranche.
  • 6:37 - 6:40
    So the $300 million from equity,
    they're going to get
  • 6:40 - 6:43
    $55 million assuming that
    there are no defaults or
  • 6:43 - 6:45
    pre-payments or anything shady
    happens with the securities.
  • 6:50 - 6:53
    But these guys are going
    to get $55 million.
  • 6:53 - 6:57
    Or on $300 million, that's
    a 16.5% return.
  • 6:57 - 6:58
    And I know what you're
    thinking.
  • 6:58 - 7:00
    Boy, Sal, that sounds amazing.
  • 7:00 - 7:03
    Why wouldn't everyone want
    to be an equity investor?
  • 7:03 - 7:04
    I don't know.
  • 7:04 - 7:05
    My pen has stopped working.
  • 7:05 - 7:08
    But anyway, I'll try to move
    on without my pen.
  • 7:08 - 7:10
    So you're saying, why wouldn't
    everyone want to
  • 7:10 - 7:11
    be an equity investor?
  • 7:11 - 7:11
    Well, let me ask
    you a question.
  • 7:11 - 7:15
    What happens if -- let's go to
    that scenario where we talked
  • 7:15 - 7:20
    before -- 20% of the borrowers
    just say, you know what?
  • 7:20 - 7:22
    I can't pay this mortgage
    anymore.
  • 7:22 - 7:24
    I'm going to hand you back
    the keys to these houses.
  • 7:24 - 7:28
    And of that 20%, you only
    get a 50% return.
  • 7:28 - 7:30
    So for each of those $1 million
    houses, you're only
  • 7:30 - 7:32
    able to sell it for $500,000.
  • 7:32 - 7:36
    So then instead of getting $100
    million per year, you're
  • 7:36 - 7:39
    only going to get $90
    million per year.
  • 7:39 - 7:40
    I wish I could use my pen.
  • 7:43 - 7:47
    Something about my computer
    has frozen.
  • 7:47 - 7:49
    So instead of $100 million a
    year, you're now only going to
  • 7:49 - 7:51
    get $90 million a year.
  • 7:51 - 7:52
    Right?
  • 7:52 - 7:53
    And all of a sudden,
    these guys are not
  • 7:53 - 7:54
    going to be cut off.
  • 7:54 - 7:56
    This guy is still going to get
    $24 million, this guy is still
  • 7:56 - 8:00
    going to get $21 million, but
    now this guy is going to get
  • 8:00 - 8:03
    $45 million.
  • 8:03 - 8:05
    But he's still getting
    above average yield.
  • 8:05 - 8:06
    Now let's say it gets
    even worse.
  • 8:06 - 8:07
    Let's say a bunch of
    borrowers start
  • 8:07 - 8:09
    defaulting on their loans.
  • 8:09 - 8:14
    And instead of getting $90
    million per year, you start
  • 8:14 - 8:17
    only getting $50 million
    in per year.
  • 8:17 - 8:19
    Now you pay this guy
    $24 million.
  • 8:19 - 8:22
    You pay this guy $21 million
    -- or this group of guys or
  • 8:22 - 8:23
    gals -- $21 million.
  • 8:23 - 8:27
    And then all you have left is
    $5 million for this guy.
  • 8:27 - 8:30
    And $5 million on $300 million,
    now he's getting less
  • 8:30 - 8:32
    than a 2% return.
  • 8:32 - 8:35
    So this guy took on higher
    risk for higher reward.
  • 8:35 - 8:39
    If everyone pays, sure,
    he gets 16.5%.
  • 8:39 - 8:43
    But then if you start having a
    lot of defaults, if, let's
  • 8:43 - 8:48
    say, the return on what you get
    every month goes in half,
  • 8:48 - 8:49
    this guy takes the entire hit.
  • 8:49 - 8:51
    So his return goes to 0%.
  • 8:51 - 8:53
    So he had higher risk,
    higher reward, while
  • 8:53 - 8:54
    these guys get untouched.
  • 8:54 - 8:57
    Of course, if enough people
    start defaulting, even these
  • 8:57 - 8:59
    people start to get hurt.
  • 8:59 - 9:02
    So this is a form of a
    collateralized debt
  • 9:02 - 9:03
    obligation.
  • 9:03 - 9:06
    This is actually a
    mortgage-backed collateralized
  • 9:06 - 9:07
    debt obligation.
  • 9:07 - 9:12
    You can actually do this type
    of a structure with any type
  • 9:12 - 9:16
    of debt obligation that's
    backed by assets.
  • 9:16 - 9:18
    So we did the situation with
    mortgages, but you could do it
  • 9:18 - 9:19
    with a bunch of assets.
  • 9:19 - 9:21
    You could do it with
    corporate debt.
  • 9:21 - 9:24
    You could do it with receivables
    from a company.
  • 9:24 - 9:27
    But what you read about the
    most right now in the
  • 9:27 - 9:30
    newspapers is mortgage-backed
    collateralized debt
  • 9:30 - 9:30
    obligations.
  • 9:30 - 9:34
    And to some degree, that's
    what's been getting a lot of
  • 9:34 - 9:35
    these hedge funds in trouble.
  • 9:35 - 9:38
    And I think I'll do another
    presentation on exactly how
  • 9:38 - 9:40
    and why they have gotten
    in trouble.
  • 9:40 - 9:43
    Look forward to talking to you
