Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application is a Continuation of pending U.S.
application Ser. No. 11/409,381, filed Apr. 21, 2006, which is a
Continuation-In-Part of pending U.S. application Ser. No.
11/122,510, filed May 4, 2005, and wherein the entirety of each of
these applications is hereby incorporated by reference herein.
TECHNICAL FIELD
[0002] The present disclosure relates to methods and systems for
creating and trading derivative investment instruments based on a
corporate debt security, such as a corporate bond.
BACKGROUND
[0003] Lending money involves risk. Regardless of who the borrower
is, be it an individual, corporation, municipality, national
government, or supranational organization such as the World Bank or
the United Nations, there is always a possibility of default. In
many cases the risk of default is remote. In others it is less so.
Interest rates on loans are determined based on, among other
things, a borrower's perceived ability to repay the loan.
Paradoxically, a borrower whose ability to repay a loan is less
certain will have pay more to borrow money in the form of higher
interest rates than a borrower who is perceived to be less of a
risk. Because debt plays a vital role in the world's economy,
assessing risk is of critical importance to ensuring the desired
flow capital from those who have it to those who would use it.
[0004] Over time, credit rating services have developed to assist
lenders and investors in assessing risk and evaluating the overall
credit worthiness of individuals and organizations. These credit
rating services produce credit ratings for individuals and
organizations that reflect the rated party's ability to repay its
debts. Investors and lenders rely on such ratings when deciding
whether to extend financing, and on what terms. In the United
States, the Securities and Exchange Commission has relied on credit
ratings by rating agencies that the markets have recognized as
credible. These "nationally recognized statistical rating
organizations" ("NRSROs") include several major credit rating
services, including A.M. Best Company, Inc. (A.M. Best), Dominion
Bond Rating Service Limited (DBRS), Moody's Investor Services
(Moody's), Standard and Poor's (S & P), and Fitch's Ratings
(Fitch's).
[0005] The rating schemes followed by the three major rating
services are all similar. Each includes multiple levels, with each
level representing a different level of risk, or a different
ranking of the perceived ability of a rated entity to meet its debt
obligations. A 1 to 3-letter code identifies each of the different
levels. For example Moody's defines nine primary risk levels:
[0006] Aaa, Aa, A, Baa, Ba, B, Caa, Ca, and C. According to this
system, the Aaa rating is reserved for the entities that
demonstrate the strongest credit worthiness. Debt issuers or debt
issues rated Aa demonstrate very strong credit worthiness but
somewhat less than those rated Aaa, while rated simply those A
represent above average credit worthiness. Issuers or issues rated
Baa represent average credit worthiness. Those rated Ba demonstrate
below average credit worthiness, and those rated B demonstrate weak
credit worthiness. Finally, issuers or issues rated Caa demonstrate
very weak credit worthiness. Those rated Ca demonstrate extremely
weak credit worthiness, and those rated C demonstrate the weakest
credit. Moody's also appends a numeric modifier 1, 2 or 3 to the
categories Aa through Caa. The numeric modifiers indicate where
within the particular risk category the entity being evaluated
falls. 1 indicates the top rating within the group. 2 indicates the
middle of the group. 3 represents the bottom. The modifiers 1, 2, 3
effectively expand the number of risk categories to a total of
twenty-one.
[0007] S&P's alphabetic rating system is similar to Moody's.
S&P defines its primary risk categories as: [0008] AAA , AA, A,
BBB, BB, B, CCC, CC, C, and D. The definitions of S&P's
categories roughly track those of Moody's and need not be
explicitly related here. S&P append a (+) or (-) to categories
AA to CCC in order to show an entity's relative standing within the
major rating categories. With the modifiers, S&P's rating
system effectively includes 16 different levels of risk.
[0009] Fitch also relies on a letter rating code similar to those
already described: [0010] AAA, AA, A, BBB, BB, B, CCC, CC, C, DDD,
DD, and D. Fitch also includes a (+) or (-) modifier to categories
AA-CCC to indicate an entities relative position within a category.
Thus, Fitch ratings may take on up to 18 different the levels.
[0011] The rating services monitor the financial health of the
organizations they rate, updating their ratings as conditions
warrant. If the rating services perceive a change in an
organization's ability to meet its obligations the rating service
may downgrade its rating of the organization. In contrast, improved
financial circumstances may cause the rating services to upgrade an
entity's credit rating. Thus, much like a company's stock price, an
entity's credit rating may serve as a barometer of the entity's
financial health.
[0012] Derivatives are financial securities whose values are
derived in part from a value or characteristic of some other
underlying asset or variable (the underlying asset). The underlying
asset may include securities such as stocks, commodities market
indicators and indexes, interest rate, and corporate debt, such as
bonds, to name but a few. Two common forms of derivatives are
options contracts and futures contracts.
[0013] An option is a contract giving the holder of the option the
right, but not the obligation, to buy or sell an underlying asset
at a specific price on or before a certain date. Generally, a party
who purchases an option is said to have taken a long position with
respect to the option. The party who sells the option is said to
have taken a short position. There are generally two types of
options: calls and puts. An investor who has taken a long position
in a call option has bought the right to purchase the underlying
asset at a specific price, known as the "strike price." If the long
investor chooses to exercise the call option, the long investor
pays the strike price to the short investor, and the short investor
is obligated to deliver the underlying asset.
[0014] Alternatively, an investor who has taken a long position in
a put option receives the right, but not the obligation to sell the
underlying asset at a specified price, again referred to as the
strike price on or before a specified date. If the long investor
chooses to exercises the put option, the short investor is
obligated to purchase the underlying asset from the long investor
at the agreed upon strike price. The long investor must then
deliver the underlying asset to the short investor. Thus, the
traditional settlement process for option contracts involves the
transfer of funds from the purchaser of the underlying asset to the
seller, and the transfer of the underlying asset from the seller of
the underlying asset to the purchaser. Cash settlement, however, is
more common. Cash settlement allows options contracts to be settled
without actually transferring the underlying asset. A call option
is "in-the-money" when the price or value of the underlying asset
rises above the strike price of the option. A put option is
"in-the-money" when the price or value of the underlying asset
falls below the strike price of the option. An at-the-money option
wherein the price or value of the underlying asset is equal to the
strike price of the option. A call option is out-of-the-money when
the price or value of the underlying asset is below the strike
price. A put option is out-of-the-money when the price or value of
the underlying asset is above the strike price. If an option
expires at-the-money or out-of-the-money, it has no value. The
short investor retains the amount paid by the long investor (the
option price) and pays nothing to the long investor. Cash
settlement of an in-the-money option, be it a call or a put,
however, requires the short investor to pay to the long investor
the difference between the strike price and the current market
value of the underlying asset.
[0015] Cash settlement allows options to be based on more abstract
underlying "assets" such as market indicators, stock indices,
interest rates, futures contracts and other derivatives. For
example, an investor may take a long position in a market index
call option. In this case, the long investor receives the right to
"purchase" not the index itself, but rather a cash amount equal to
the value of the index (typically multiplied by a multiplier) at a
specified strike value. An index call option is in-the-money when
the value of the index rises above the strike value. When the
holder of an in-the-money index call option exercises the option,
the short investor on the opposite side of the contract is
obligated to pay the long investor the difference between the
current value of the index and the strike price, usually multiplied
by the multiplier. If the current value of the index is less than
or equal to the strike value, the option has no value. An index put
option works in the same way but in reverse, having value, or being
in-the-money when the value of the index falls below the strike
value.
[0016] Futures contracts are another common derivative security. In
a futures contract a buyer purchases the right to receive delivery
of an underlying commodity or asset on a specified date in the
future. Conversely, a seller agrees to deliver the commodity or
asset to an agreed location on the specified date. Futures
contracts originally developed in the trade of agricultural
commodities, but quickly spread to other commodities as well.
Because futures contracts establish a price for the underlying
commodity in advance of the date on which the commodity must be
delivered, subsequent changes in the price of the underlying asset
will inure to the benefit of one party and to the detriment of the
other. If the price rises above the futures price, the seller is
obligated to deliver the commodity at the lower agreed upon price.
The buyer may then resell the received product at the higher market
price to realize a profit. The seller in effect loses the
difference between the futures contract price and the market price
on the date the goods are delivered. Conversely if the price of the
underlying commodity falls below the futures price, the seller can
obtain the commodity at the lower market price for delivery to the
buyer while retaining the higher futures price. In this case the
seller realizes a profit in the amount of the difference between
the current market price on the delivery date and the futures
contract price. The buyer sees an equivalent loss.
[0017] Like options contracts, futures contracts may be settled in
cash. Rather than actually delivering the underlying asset, cash
settlement merely requires payment of the difference between the
market price of the underlying commodity or asset on the delivery
date and the futures contract price. The difference between the
market price and the futures price is to be paid by the short
investor to the long investor, or by the long investor to the short
investor, depending on which direction the market price has moved.
If the prevailing market price is higher than the contract price,
the short investor must pay the difference to the long investor. If
the market price has fallen, the long investor must pay the
difference to the short investor.
[0018] Again, like options, cash settlement allows futures
contracts to be written against more abstract underlying "assets"
or "commodities," such as market indicators, stock indices,
interest rates, futures contracts and other derivatives. For
example, an investor may take a long position in a market index
futures contract. In this case, the long investor "buys" the index
at a specified futures price (i.e. a future value of the index on
the "delivery" date). The index based futures contract is cash
settled. One party to the contract pays the difference between the
futures price and the actual value of the index (often multiplied
by a specified multiplier) to the other investor depending on which
direction the market has moved. If the value of the index has moved
above the futures price, or futures value, the short investor pays
the difference the long investor. If the value of the index has
moved below the futures price, or futures value the long investor
pays the difference to the short investor.
[0019] Cash settlement provides great flexibility regarding the
types of underlying assets that derivative investment instruments
may be built around. Essentially any variable whose value is
subject to change over time, may serve as the underlying asset for
a derivative investment instrument. While standard derivatives may
be based on many different underlying assets, there is a need for
derivative investment instruments that relate to the financial
health of various organizations.
SUMMARY
[0020] The present invention relates to systems and methods for
creating and trading corporate debt security derivative investment
instruments. A corporate debt security derivative investment
instrument is an instrument that derives its value based on the
credit rating of an entity such as a corporation, municipal
government, national government, or supranational organization. The
risk categories of an independent credit rating service's rating
scheme are mapped to individual monetary values. When an entity is
rated by the credit rating service, the rating service assigns a
risk level that identifies the perceived credit worthiness of the
rated entity. The applicable rating may change over time according
to the financial health of the rated entity. As the rated entity's
credit rating rises and falls, so do the values to which the
various ratings are mapped. According to one aspect, corporate debt
security derivative investment instruments such as corporate debt
security options may be created which are based on the mapped
values associated with an entity's credit rating.
[0021] A method of creating and trading corporate debt security
derivative investment instruments may include identifying a credit
rating service that rates various entities and organizations using
a credit rating scheme that includes a plurality of risk
categories. The credit rating service rates an entity's credit
worthiness by associating a risk category with the entity that
accurately reflects the credit rating services assessment of the
rated entities credit worthiness. The various risk categories are
mapped to unique monetary values, such that if the risk category
associated with a rated entity is changed, i.e. upgraded or
downgraded, the mapped value will likewise change accordingly.
Next, an entity that is rated by credit rating service is
identified. Derivative investment instruments such as corporate
debt security call and put options and futures contracts may be
created based on the monetary values to which the rated entity's
credit rating is mapped. The value of the corporate debt security
derivative investment instrument is determined at least in part by
the monetary value to which the current risk category associated
with the rated entity is mapped.
[0022] According to another aspect, a method of creating a
derivative investment instrument based on a corporate bond is
provided. The method includes identifying a corporate bond as an
underlying security for the derivative investment instrument and
associating the underlying security with an exercise price, wherein
the exercise price is listed on an exchange. A corporate bond
security derivative instrument is generated whose value is
determined at least in part by the exercise price to which the
underlying security is associated.
[0023] According to yet another aspect, a method of selecting a
corporate bond for use in a derivative investment instrument based
thereon is provided. The method includes identifying at least one
eligible corporate bond in accordance with predefined listing
standards, sorting the at least one eligible corporate bond based
on a rating and a maturity, aggregating trade information for the
at least one eligible corporate bond, and ranking the at least one
eligible corporate bond based on the trade information.
[0024] Other systems, methods, features and advantages of the
invention will be, or will become, apparent to one with skill in
the art upon examination of the following figures and detailed
description. It is intended that all such additional systems,
methods, features and advantages be included within this
description, be within the scope of the invention, and be protected
by the appended claims.

DETAILED DESCRIPTION
[0031] As described herein, derivative investment instruments are
disclosed that are based on the movements of an organization's
credit rating. In the same way that traditional options and futures
contracts derive their value based on changes in the market price
or value of an underlying asset, the disclosed derivative
investments derive their value based on changes in an entity's
credit rating. The credit rating derivatives may encompass options
and futures-type instruments and may be traded on an exchange, in
an open outcry format, electronically or in a combination of open
outcry and electronic formats.
[0032] According to one embodiment, the various credit rating
levels of a credit rating service's rating scheme are mapped to
specific monetary values. For example, FIG. 1 shows a table 10
mapping the primary risk categories of S&P's credit rating
scheme to various dollar amounts. Table 10 includes two columns.
The first column 12 contains the letter ratings defining the
different risk categories. As described above, the S&P credit
rating scheme includes nine primary risk categories AAA, AA, A,
BBB, BB, B, CCC, CC, and C. (The number of categories is actually
expanded by the addition of the (+) and (-) modifiers to rating
categories AA-CCC but, for ease of illustration, the modifiers have
been omitted.) The second column 14 contains the dollar values to
which the primary risk categories of column 12 are mapped. In the
present example, the highest rating AAA is mapped to $125. AA is
mapped to $120 and so forth in $5 decrements until the lowest
rating C is mapped to $85.
[0033] The mapping of risk categories to monetary values is
substantially arbitrary. A different credit rating scheme may be
employed having more or less risk categories. For example, Moody's
or Fitch's rating systems may have been employed. The modifiers
(1), (2), (3) or (+) and (-) may be included to increase the number
of risk categories, (increasing the number of mapped values as a
result). Or a different rating scheme altogether may be selected. A
different currency may be employed as the monetary unit for column
14. Different mapped values may be employed, with different
increments there between. The only restriction regarding the
selection of the mapped values is that the mapped values progress
in a logical manner that corresponds with the progression of their
associated risk categories.
[0034] The monetary values to which the various credit rating risk
categories are mapped have many similarities with corporate share
prices, commodity prices, and market indexes. It is preferred that
only a single risk category (AAA, AA, A, etc.) 16, will be applied
to a rated entity (corporation, municipal government, national
government, supranational, etc.) at any given time. However, the
credit rating risk category applied to describe the entity's credit
worthiness may in fact change over time depending on the rated
entity's perceived ability to repay its debts. As the credit rating
risk category changes, the mapped monetary value changes with it.
For example, for an entity having a B credit rating the associated
mapped value is $100. If the entity's credit rating is upgraded to
BB, the corresponding mapped value is $105. Similarly, if the
entity's rating is downgraded to CCC, the corresponding mapped
value is $95. Thus, just like a company's share price, which moves
up and down with the company's performance, or just as a market
index goes up and down based on the performance of a group of
stocks, or just as commodity prices move up and down based on
supply and demand, so the mapped values associated with an entity's
credit rating will rise and fall with chances in the entity's
perceived ability to pay its debts. And just as derivative
investment instruments may be written based on corporate share
prices, market indexes or commodity prices, so to may derivative
investment instruments be written based on the monetary values
associated with an entity's credit rating.
[0035] A corporate debt security call option may be created as
follows. A long investor may choose to buy the right to "purchase"
an entity's corporate debt security at a specified category or
strike value, such as BB or $105, the value to which a BB credit
rating is mapped. If the entity's credit rating improves before
expiration of the option, for example if the entity's credit rating
is upgraded to AA, the call option will be in-the-money. This
situation corresponds exactly with a standard in-the-money call
option based on a company's share price. When a corporate share
price rises above the strike price, a call option is in-the-money.
The long investor is entitled to collect the difference between the
actual share price and the strike price. In the case of the
corporate debt security call option, the strike price is the credit
rating category BB, or the corresponding mapped value $105. When
the entity's credit rating is upgraded to AA, the current credit
rating is several levels above the BB strike rating. Similarly, the
value mapped to the current credit rating, $120, is $15 above the
BB strike price. Or we can say that the value or price to $105
corresponds to the value to which the BB strike rating is mapped.
The long investor bought the right to "purchase" the entity's
corporate debt security at BB or $105, since current rating is AA,
which maps to $120, the long investor is entitled to collect the
difference between the present value $120 and the strike value $105
or a total of $15. Since the corporate debt security option is to
be settled in cash, the short investor who sold the option is
obligated to pay the $15 to the long investor.
[0036] A corporate debt security put option operates in much the
same way, only in reverse. A long investor may choose to buy the
right to "sell" an entity's corporate debt security at a specified
category or strike value such A or $115, the value to which an A
credit rating is mapped. If the entity's credit rating is
downgraded to a level below A before the expiration of the option,
for example if the entity's credit rating is downgraded to CC, the
corporate debt security put option will be in-the-money. This
situation corresponds exactly with an in-the-money put option based
on a company's share price. When a corporate share price falls
below the strike price, the put option is in-the-money. The short
investor who sold the option must pay the difference between the
current share price and the strike price to the long investor. In
the case of the present corporate debt security put option, the
strike rating is AA. This maps to a strike value or strike price,
of $120. When the entity's credit rating is downgraded CC, the
credit rating is several levels below the A strike rating.
Similarly, value to which the CC rating is mapped, $90, is lower
than the $115 value to which the strike value is mapped. In this
case, the long investor bought the right to "sell" the corporate
debt security at A or $115. Since the current rating is CC which
maps to $90, the long investor is entitled to collect the
difference. Since the corporate debt security option is to be cash
settled, the short investor is obligated to pay the $25 difference
between A strike rating ($120) and the current CC rating ($90).
[0037] In another example, a corporate debt security may be in the
form of a corporate bond and a derivative investment instrument
based on the corporate bond can be created. A corporate bond is
type of bond that is issued by a corporation. Corporate bonds tend
to pay higher rates than other bonds due to their increased level
of risk. Generally, the bondholder receives interest payments
(yield) and the principal is repaid on a fixed maturity date
(between 1 to 30 years). Corporate bonds have a wide range of
ratings and yields because the financial stability of the issuers
can vary widely. A high-quality blue chip company might have bonds
carrying an investment-grade rating such as AA (with a low yield
but a lower risk of default), while a startup company might have
bonds carrying a "junk bond" rating (with a high yield but a higher
risk of default). In such an example, a corporate bond is
identified as an underlying security for the derivative investment
instrument. The underlying security is then associated with an
exercise price, with the exercise price listed on an exchange. The
resulting corporate bond security derivative instrument is
generated with a value that is determined at least in part by the
exercise price to which the underlying security is associated
Likewise, a method of selecting a corporate bond for use in a
derivative investment instrument can be accomplished by identifying
at least one eligible corporate bond in accordance with predefined
listing standards, such as those detailed in the examples herein.
The identified eligible corporate bond(s) are then sorted based on
a rating and a maturity, with trade information aggregated for the
eligible corporate bond(s). The identified eligible corporate
bond(s) are subsequently ranked based on the trade information.
Such corporate bond-based derivative investment instruments may
include call and/or put options.
[0038] Next we will consider a credit rating futures contract.
Again referring to the table 10 in FIG. 1, the values to which the
various credit rating risk categories are mapped may function as
the commodity or asset price for a credit rating futures contract.
A long investor may anticipate that a particular entity's credit
rating will be at or above a certain level at some time in the
future. A short investor may hold the opposite view that the
entity's credit rating will in fact be below the level anticipated
by the long investor. For example, assume that the long investor
believes the entity's credit rating will be at A or above BB rating
and the short investor believes it will be below that level on a
specified date in the future.
[0039] The long and short investors may then enter into a futures
agreement wherein the long investor agrees to "buy" the entity's
credit rating on the specified date for the amount corresponding to
the BB rating, or $105. If, on the specified date, the entity's
credit rating has been upgraded to a level above the BB futures
rating, the short investor will be obligated to pay the difference
between the value to which the actual credit rating is mapped, and
the $105 value to which the BB futures rating is mapped. For
example, if the entity's credit rating had been upgraded and stands
at AAA on the specified date, the short investor would be obligated
to pay the long investor the difference between $125, the value to
which an AAA rating is mapped, and $105, the value to which the BB
futures rating is mapped, for a total of $20. Conversely, if on the
specified date the entity's credit rating has been downgraded to a
level below the futures rating, the long investor will be obligated
to pay the difference between the value to which the actual credit
rating is mapped and the $105 value to which the BB futures rating
is mapped. For example, if the entity's credit rating had been
downgraded and stands at C rating on the expiration date, the long
investor would be obligated to pay to the short investor the
difference between $85, the value to which a C credit rating is
mapped, and $105, the value to which the BB futures credit rating
is mapped, or a total of $20.
[0040] FIG. 2 shows a flow chart of a method of creating and
trading corporate debt security derivative investment instruments.
According to one embodiment, step S1 is to identify a credit rating
service whose rating of an entity or organization will serve as the
basis of a derivative investment instrument. Step S2 is to map the
various risk categories of the rating services rating scheme to
specific monetary values. Step S3 is to identify an entity which is
rated by the credit rating service identified in Step S1, and whose
credit rating is to serve as the basis for the corporate debt
security derivative instruments. Step S4 is to specify a corporate
debt security derivative instrument based on the credit rating of
the entity identified in Step S3 and the monetary values to which
the credit risk categories of the credit rating service's rating
scheme are mapped to. Step S5 is to create a market for the
corporate debt security derivative instrument. Step S6 is to accept
bids, offers and purchase orders for both long and short positions
corporate debt security derivative instruments which are to be
created according to the corporate debt security derivative
investment instrument specified in step S4. Step S7 is to execute
corporate debt security derivative investment instrument by
matching corresponding orders for long and short positions. And,
finally, step S8 is to settle positions in the executed corporate
debt security derivative investment instruments.
[0041] The corporate debt security derivative investment
instruments discussed herein may be traded on an exchange. The
exchange may be a traditional open outcry exchange, or it may be an
electronic trading platform such as the Chicago Board Options
Exchange (CBOE) Futures Network (CFN). Employing the method
outlined in FIG. 2, the exchange may from time to time identify
entities whose credit ratings may be of interest to investors. The
exchange may decide to specify corporate debt security derivative
investment instruments such as corporate debt security option
contracts based on the entities credit rating, as determined by an
independent credit rating service.
[0042] Creating a market for the corporate debt security derivative
investment instruments may be accomplished by listing one or more
specified contracts on an exchange or trading platform. Listing a
contract includes disseminating information about the contract to
potential investors and providing a mechanism whereby investors may
make bids and offers and place orders for the contracts. Corporate
debt security derivative investment instruments may be traded on a
trading facility which disseminates information regarding contracts
traded on the platform, and allows brokers and dealers to place
orders for customers who enter bids and make offers to buy and sell
positions in such contracts. One suitable trading platform is the
CBOEdirect.RTM. electronic trading platform in use at the Chicago
Board Options Exchange, Incorporated of Chicago, Ill.
[0043] Essentially, once a contract is defined and listed, the
CBOEdirect electronic trading platform, in conjunction with other
backend systems of the exchange, is responsible for all of the
remaining steps of the method shown in FIG. 2. CBOE direct accepts
bids and offers from investors or brokers (Step S6), and executes
marketable orders by matching buyers to sellers (Step S7), and
settles the contracts (Step S8).
[0044] FIG. 3 shows an electronic trading system 300 which may be
used for listing and trading corporate debt security derivative
investment instruments. The system 300 includes components operated
by an exchange, as well as components operated by others who access
the exchange to execute trades. The components shown within the
dashed lines are those operated by the exchange. Components outside
the dashed lines are operated by others, but nonetheless may be
used in the operation of a functioning exchange. The exchange
components of the trading system 300 include an electronic trading
platform 320, a member interface 308, a matching engine 310, and
backend systems 312. Some backend systems that may be operated by
entities separate from the exchange and are integrated into the
tasks of processing trades and settling contracts may include the
Clearing Corporation's systems 314, and member firms' backend
systems 316.
[0045] Market makers may access the trading platform 320 directly
through personal input devices 304 which communicate with the
member interface 308. Market makers may quote prices for digital
futures contracts. Non-member customers 302, however, must access
the exchange through a member firm. Customer orders are routed
through member firm routing systems 306. The member firms' routing
systems 306 forward the orders to the exchange via the member
interface 308. The member interface 308 manages all communications
between the member firm routing systems 306 and market makers'
personal input devices 304; determines whether orders may be
processed by the trading platform; and determines the appropriate
matching engine for processing the orders. Although only a single
matching engine 310 is shown in FIG. 3, the trading platform 320
may include multiple matching engines. Different exchange traded
products may be allocated to different matching engines for
efficient execution of trades. When the member interface 302
receives an order from a member firm routing system 306, the member
interface 308 determines the proper matching engine 310 for
processing the order and forwards the order to the appropriate
matching engine. The matching engine 310 executes trades by pairing
corresponding marketable buy/sell orders. Non-marketable orders are
placed in an electronic order book.
[0046] Once orders are executed, the matching engine 310 may send
details of the executed transactions to the exchange backend
systems 312, to the Clearing Corporation systems 314, and to the
member firms' backend systems 316. The matching engine may also
update the order book to reflect changes in the market based on the
executed transactions. Orders that previously were not marketable
may become marketable due to changes in the market. If so, the
matching engine 310 may execute these orders as well.
[0047] The exchange backend systems 312 perform a number of
different functions. For example, contract definition and listing
data originate with the exchange backend systems 312. Pricing
information for corporate debt security derivative investment
instruments is disseminated from the exchange backend systems to
market data vendors 318. Customers 302, market makers 304, and
others may access the market data regarding derivative investment
instruments via, for example, proprietary networks, on-line
services, and the like. The exchange backend systems also monitor
the credit ratings of the entities on which the derivative
investment instruments are based. At settlement, the backend
systems 312 determine the appropriate settlement amounts and supply
final settlement data to the Clearing Corporation. The Clearing
Corporation acts as the exchange's bank and performs a final
mark-to-market on member firm margin accounts based on the
positions taken by the member firms' customers. The final
mark-to-market reflects the final settlement amounts for corporate
debt security derivate investment instruments, and the Clearing
Corporation debits/credits member firms' accounts accordingly.
These data are also forwarded to the member firms' systems 316 so
that they may update their customer accounts as well.
[0048] FIG. 4 shows an example of exchange backend systems 312
suitable for trading corporate debt security derivative investment
instruments in more detail. A corporate debt security derivative
investment instrument definition model definition module 340 stores
all relevant data concerning the corporate debt security derivative
investment instrument, to be traded on the trading platform 320,
including the contract symbol, the identity of the rated entity,
the rating service, mapping of the credit risk categories to the
monetary values, strike prices futures prices and the like. A
pricing data accumulation and dissemination module 348 receives
contract information from the corporate debt security derivative
investment instrument definition module 340 and transaction data
from the matching engine 310. The pricing data accumulation and
dissemination module 348 provides the market data regarding open
bids and offers and recent transactions to the market data vendors
318. The pricing data accumulation and dissemination module 348
also forwards transaction data to the Clearing Corporation so that
the Clearing Corporation may mark-to-market the accounts of Member
Firms at the close of each trading day, taking into account current
market prices for the corporate debt security derivative investment
instruments. Finally, a settlement calculation module 346 receives
input from the credit rating service when a corporate debt security
derivative investment instrument is settled, the settlement date
the settlement calculation module 346 calculates the settlement
amount based on the rated entity's present rating and the monetary
value to which it is mapped. The settlement calculation module 346
forwards the settlement amount to the Clearing Corporation, which
performs a final mark-to-market on the Member Firms' accounts to
settle the corporate debt security derivative investment
instrument.
[0049] According to another embodiment, chooser options may be
created based on corporate debt security options. A chooser option
is an option wherein the purchaser of the option buys a call or a
put option at some time in the future. The call and the put option
will typically share the same expiration date and the same strike
price (value), although, split chooser options may be crafted
wherein the call and the put options have different expirations
and/or different strikes.
[0050] Chooser options are advantageous in situations in which
investors believe that the price of the underlying asset is due for
a significant move, but the direction of the move is in doubt. For
example, some event, such as the approval (disapproval) of a new
product, a new earnings report, or the like, may be anticipated
such that positive news is likely to cause the share price to rise,
and negative news will cause the share price to fall. The ability
to choose whether an option will be a put or a call having
knowledge of the outcome of such an event is a distinct advantage
to an investor.
[0051] The purchase of a chooser option is akin to purchasing both
a put and a call option on the same underlying asset. Typically,
the chooser option is priced accordingly. In the present case,
purchasing a corporate debt security chooser option amounts to
buying both a put and a call option based on the credit rating of a
rated entity. Chooser options may be traded on an exchange just
like other corporate debt security derivative investment
instruments. The only accommodations necessary for adapting an
exchange for trading chooser options is that a final date for
making the choice between a call option and a put option must be
established and maintained. Also, post-trade processing on the
exchange's systems must be updated to implement and track the
choice of the call or a put once the choice has been made. One
approach for processing the chosen leg of a chooser option is to
convert the chooser option into a standard option contract
according to the standard series for the same underlying asset and
having the same strike price as the chosen leg of the chooser
option.
[0052] Referring now to FIG. 5, an illustrative embodiment of a
general computer system that may be used for one or more of the
steps and/or components shown in FIGS. 2 through 4, or in any other
trading system configured to carry out the methods discussed above,
is shown and is designated 400. The computer system 400 can include
a set of instructions that can be executed to cause the computer
system 400 to perform any one or more of the methods or computer
based functions disclosed herein. The computer system 400 may
operate as a standalone device or may be connected, e.g., using a
network, to other computer systems or peripheral devices.
[0053] In a networked deployment, the computer system may operate
in the capacity of a server or as a client user computer in a
server-client user network environment, or as a peer computer
system in a peer-to-peer (or distributed) network environment. The
computer system 400 can also be implemented as or incorporated into
various devices, such as a personal computer (PC), a tablet PC, a
set-top box, a personal digital assistant (PDA), a mobile device, a
palmtop computer, a laptop computer, a desktop computer, a network
router, switch or bridge, or any other machine capable of executing
a set of instructions (sequential or otherwise) that specify
actions to be taken by that machine. In a particular embodiment,
the computer system 400 can be implemented using electronic devices
that provide voice, video or data communication. Further, while a
single computer system 400 is illustrated, the term "system" shall
also be taken to include any collection of systems or sub-systems
that individually or jointly execute a set, or multiple sets, of
instructions to perform one or more computer functions.
[0054] As illustrated in FIG. 5, the computer system 400 may
include a processor 402, e.g., a central processing unit (CPU), a
graphics processing unit (GPU), or both. Moreover, the computer
system 400 can include a main memory 404 and a static memory 406
that can communicate with each other via a bus 408. As shown, the
computer system 400 may further include a video display unit 410,
such as a liquid crystal display (LCD), an organic light emitting
diode (OLED), a flat panel display, a solid state display, or a
cathode ray tube (CRT). Additionally, the computer system 400 may
include an input device 412, such as a keyboard, and a cursor
control device 414, such as a mouse. The computer system 400 can
also include a disk drive unit 416 and a network interface device
420.
[0055] In a particular embodiment, as depicted in FIG. 5, the disk
drive unit 416 may include a computer-readable medium 422 in which
one or more sets of instructions 424, e.g. software, can be
embedded. Further, the instructions 424 may embody one or more of
the methods or logic as described herein. In a particular
embodiment, the instructions 424 may reside completely, or at least
partially, within the main memory 404, the static memory 406,
and/or within the processor 402 during execution by the computer
system 400. The main memory 404 and the processor 402 also may
include computer-readable media.
[0056] In an alternative embodiment, dedicated hardware
implementations, such as application specific integrated circuits,
programmable logic arrays and other hardware devices, can be
constructed to implement one or more of the methods described
herein. Applications that may include the apparatus and systems of
various embodiments can broadly include a variety of electronic and
computer systems. One or more embodiments described herein may
implement functions using two or more specific interconnected
hardware modules or devices with related control and data signals
that can be communicated between and through the modules, or as
portions of an application-specific integrated circuit.
Accordingly, the present system encompasses software, firmware, and
hardware implementations.
[0057] In accordance with various embodiments of the present
disclosure, the methods described herein may be implemented by
software programs executable by a computer system. Further, in an
exemplary, non-limited embodiment, implementations can include
distributed processing, component/object distributed processing,
and parallel processing. Alternatively, virtual computer system
processing can be constructed to implement one or more of the
methods or functionality as described herein.
[0058] The present disclosure contemplates a computer-readable
medium that includes instructions 424 or receives and executes
instructions 424 responsive to a propagated signal, so that a
device connected to a network 426 can communicate voice, video or
data over the network 426. Further, the instructions 424 may be
transmitted or received over the network 426 via the network
interface device 420.
[0059] While the computer-readable medium is shown to be a single
medium, the term "computer-readable medium" includes a single
medium or multiple media, such as a centralized or distributed
database, and/or associated caches and servers that store one or
more sets of instructions. The term "computer-readable medium"
shall also include any medium that is capable of storing, encoding
or carrying a set of instructions for execution by a processor or
that cause a computer system to perform any one or more of the
methods or operations disclosed herein.
[0060] In a particular non-limiting, exemplary embodiment, the
computer-readable medium can include a solid-state memory such as a
memory card or other package that houses one or more non-volatile
read-only memories. Further, the computer-readable medium can be a
random access memory or other volatile re-writable memory.
Additionally, the computer-readable medium can include a
magneto-optical or optical medium, such as a disk or tapes or other
storage device to capture carrier wave signals such as a signal
communicated over a transmission medium. A digital file attachment
to an e-mail or other self-contained information archive or set of
archives may be considered a distribution medium that is equivalent
to a tangible storage medium. Accordingly, the disclosure is
considered to include any one or more of a computer-readable medium
or a distribution medium and other equivalents and successor media,
in which data or instructions may be stored.
[0061] Although the present specification describes components and
functions that may be implemented in particular embodiments with
reference to particular standards and protocols commonly used on
financial exchanges, the invention is not limited to such standards
and protocols. For example, standards for Internet and other packet
switched network transmission (e.g., TCP/IP, UDP/IP, HTML, HTTP)
represent examples of the state of the art. Such standards are
periodically superseded by faster or more efficient equivalents
having essentially the same functions. Accordingly, replacement
standards and protocols having the same or similar functions as
those disclosed herein are considered equivalents thereof.
[0062] The method of creating and trading corporate debt security
derivative investment instruments and the system for trading such
instruments provides investors with a vehicle for taking position
relative to changes in various organizations' credit ratings. The
ability to take positions regarding organization's credit ratings
provides investors with additional tools for managing and
diversifying investment risks.
[0063] While various embodiments of the invention have been
described, it will be apparent to those of ordinary skill in the
art that many more embodiments and implementations are possible
within the scope of the invention. Accordingly, the invention is
not to be restricted except in light of the attached claims and
their equivalents.
