Mortgage-backed securities III
So just to simplify. Keep it in your mind. $1 billion goes to a bunch of borrowers, goes to 1,000 borrowers, to be specific.발음듣기
And then we said, OK, well where does that money for this special purpose entity, or for this corporation, come from?발음듣기
And so money came from when the owners of each of these mortgage-backed securities - each, let's say, paid $1,000 for the mortgage-backed securities.발음듣기
And we said there are a million of these securities, so $1,000 times 1 million, that's where the $1 billion comes from.발음듣기
Now one thing I want you to keep in mind is, they get 10% only if every one of these borrowers pays their loans, never defaults, never pre-pays.발음듣기
So it's only 10%, indefinitely, if all of the borrowers pay all the money and never default or anything like that.발음듣기
And actually that's what the buyer of the mortgage-backed security should try to figure out.발음듣기
And this is what you probably read some articles about, these hedge funds with these computer models to value their mortgage-backed securities.발음듣기
OK, for a given population pool in a given part of the country, what percentage of them are able to pay off their mortgage?발음듣기
Say they default on a $1 million mortgage, and then the special purpose entity would get control of that house.발음듣기
And then if that house is sold for $500,000 because the property value went down, then the recovery would be 50%.발음듣기
So that's all of the things that someone needs to factor in when they figure out what will be the real return.발음듣기
Let's say we are thinking about investing in a mortgage-backed security and we want to gauge for ourselves what we think the return is going to be.발음듣기
Well let's say we know that this pool of borrowers that - my pen keeps not working - that 20% will default.발음듣기
And then when we go and get the property - because the loan was secured by the property - when we auction off the property, we only get $500,000 for it.발음듣기
So if 20% default and then there's a 50% recovery, then on average you're going to get 10% of the loan is worthless.발음듣기
But you can assume statistically, and since this is a large number of borrowers - it's 1,000, right?발음듣기
If there's only one borrower it would be hard to kind of gauge when he defaults, if he defaults at all.발음듣기
But when there's a large number of borrowers, you can kind of do the math and say, OK, on average 200 of these guys are going to default,발음듣기
and instead of actually getting 10%, since 10% of the loans are going to be worthless, I'm going to get 10% less than this 10%.발음듣기
But based on the model that we just constructed, I think the real return we're going to get on this mortgage-backed security is 9%.발음듣기
but with a higher recovery, he or she would have a different kind of expected return from this security.발음듣기
Before, in the case we did in the first video, when someone just borrows from the bank, the bank has very specific lending requirements.발음듣기
Right? There might be people with really good credit scores, really good incomes, who don't have a down payment.발음듣기
For the right interest rate and for the right assumptions in my model, I'm willing to give anybody a loan, as long as I'm compensated for it enough.발음듣기
It allows - let's say this group of borrowers - let's say this pool of borrowers right here actually didn't--발음듣기
they don't have 25% down and they don't have kind of the traditional requirements to get a normal mortgage--발음듣기
but if I pool a bunch of people who don't have those traditional requirements, but they're good in other ways--발음듣기
I can go through this alternate mechanism to find investors that are willing to loan them money.발음듣기
So essentially, from the borrower's point of view, it allows more access to loan funding that they would have otherwise not been able to.발음듣기
Maybe I feel that the computer models that I have are really good at predicting things like default rates, and recovery rates, and what a loan is worth.발음듣기
It also might just have a risk reward characteristic that doesn't exist in the market already, and it allows you to diversify into one other asset class.발음듣기
Now in the next presentation I'm going to show how you can, I guess, further complicate this even more, so that you can open up the investment to even a larger group of investors.발음듣기
Because you can think about it right now, there's probably some people who say, OK, I already said, some people will do these models and try to make their own assumptions and say, OK, this is going to give me 9% a year.발음듣기
But there's a whole bunch of people who are going to say this is just too complicated for me.발음듣기
And there's another group of people who say, OK, 9%, that's nice and everything, but I'm a hotshot, I'm a gambler.발음듣기
