US Patent:
7574394, Aug 11, 2009
Filed:
Feb 16, 2006
Appl. No.:
11/354866
Inventors:
Douglas T. Chorna - Delray Beach FL, US
Srikanth Sankaran - Winnetka IL, US
Assignee:
SRI, Inc. - Northfield IL
Cayuga Derivatives, Inc. - Delray Beach FL
International Classification:
G06Q 40/00
US Classification:
705 36, 705 37
Abstract:
An exchange-traded financial instrument having a price that tracks an underlying benchmark, the underlying benchmark being a security or commodity that is itself traded. A contract for the financial instrument between a buyer and seller is not contingent upon the delivery of the underlying benchmark. A net carrying charge (credit or debit), defined as the difference between the investment yield of the underlying benchmark and a cost of financing ownership of the underlying benchmark using the generally accepted industry standard financing rate for that benchmark, is credited or debited, accrued, or built into the price of the derivative for both buyer and seller of the financial instrument, typically nightly. In one embodiment, the underlying benchmark is a U. S. Treasury security, and preferably a specific U. S.

US Patent:
20080097895, Apr 24, 2008
Filed:
Dec 19, 2007
Appl. No.:
11/960397
Inventors:
Srikanth Sankaran - Winnetka IL, US
Douglas Chorna - Delray Beach FL, US
International Classification:
G06Q 40/00
US Classification:
705037000, 705035000
Abstract:
A method and system for underwriter offering of multi-class instruments including a central processing unit (CPU), a program memory, a structure database and an investor database. The structure database stores a structure representative of a plurality of classes of a multi-class instrument, and the system operates to (i) inform investors of class information related, respectively, to each class of the multiclass instrument, (ii) receive bid information from investors, (iii) modify the structure database in response to the bid information and subsequently inform investors with updated class information; and once it is determined that the underwriter can profitably underwrite the transaction, (iv) notify the underwriter of an amount of collateral to purchase to cover accepted bids.
