Basis Rate Swap
  
A mortgage company issues variable rate mortgages tied to the LIBOR rate (London Interbank Offer), but when they borrow money it's based on the Treasury Bill rate (which is based on an alternate money market). The spread (or difference) between the lending and borrowing rates results in interest rate risk, so they undertake a basis rate swap, exchanging the LIBOR and Treasury Bill rates, thereby eliminating the risk.
In other words, variable interest rates based on alternate money markets were switched out to lessen the inherent risk the mortgage company would face from using different borrowing and lending rates.

finance a la shmoop what is a realized gain or loss hey whoa whoa yes those are
all the sounds of realization oh and golly gee willikers yes that too well [Man looking surprised]
when you realize a gain or loss it means that you've turned an investment into
cash if your investment has been profitable then you've realized a gain [Cash stacks landing on each other]

doesn't roll why is it important to understand realized gains and losses
rhymes with shmaxes well the government at least thus far does not tax Americans
on the assets they have rather it taxes them only when they convert those assets
into cash assets like stocks bonds real estate appreciated crayon drawings that
got sold on eBay for a big price if someone pays you cash then its taxable [eBay crayon listing appears]
the idea being that an investment in a vacuum by itself isn't all that useful
like owning shares in a private company that's probably worth a lot more but may
or may not be worth anything later when you go to sell it or even if that
company's public you own a lot of shares in it well until you turn them into cash [Shares transform into cash]
nothing is certain because even public companies can go down a whole lot in
value so the government keeps its sticky paws off of those things things that are
just investments and only comes a-knockin when the investments are
converted into cash and you know that cash can be used to do stuff like buy [Investment assets transform into pile of cash]
cars and pay tuition and rent and get the occasional multicolored water slide

after one year that is when you've made an investment and held it for at least a
year and then you go to sell it well you generally get a lower tax rate
applied to you then you would have had you held that investment less than a
year why well if you're holding it a year the government wants to reward you [Man holding stocks]
and it makes the markets more stable when you hold the investments
long period of time so they give you a tax break by encouraging people to marry
investments holding them many years instead of just dating them for a few [Man at altar with investment bride]
weeks while one goal the politicos have is to create a more stable predictable
investment climate it makes a lot of sense all right and predictable is good
