  • Patent number: 8090638
    Abstract: A system and method for providing an extendable swap is provided. In a preferred embodiment, two parties enter into an ISDA Master Agreement and then negotiate one or more OTC derivative transaction agreements, including interest rate swaps, cross-currency swaps, commodity swaps, equity swaps and/or currency swaps. The parties negotiate terms including conditions precedent to the automatic extension of the extendable swap. Where the condition(s) precedent are met at the end of a period, the agreement automatically renews for another period (with the same terms), up to a final termination date. Where the conditions precedent are not met, the contract in not renewed, and the agreement terminates on the relevant anniversary date. Such a swap enables a party to offer better pricing due to period valuations and probabilities that are used to calculate the price of the swap.

  • Patent number: 8015105
    Abstract: In one aspect, the invention comprises entering into an agreement with a borrower to provide a loan of a specified amount on a specified date, wherein the agreement further specifies a fixed rate and a spread; and on the specified date specifying whether the borrower must pay a fixed coupon at the fixed rate or pay a floating coupon based on the spread. In another aspect, the invention comprises an agreement between a lender and a borrower whereby the lender provides to the borrower a loan of a specified amount on a specified date; a fixed rate and a spread are specified; and the borrower receives the specified amount on the specified date, and during the term pays, at lender's option to be specified on the specified date, either a fixed coupon at the fixed rate or a floating coupon at a floating rate based on the spread.

  • Patent number: 7024383
    Abstract: A computer-implemented method for providing risk management for online transactions. An exchange price for a foreign currency relative to a base currency is entered into a host computer. The host computer will also receive data descriptive of one or more transactions involving the foreign currency that occurred within a predetermined time period. The data will include a transaction amount. Currency is exchanged according to the entered price and the transaction amounts contained in the data. A risk exposure for the predetermined time period can be calculated based upon an aggregate amount of currency involved in transactions during the predetermined time period. The risk exposure can be based upon market data relating to the price of the foreign currency. The present invention can be implemented to capture each transaction amount that relates to a sale occurring on an e-commerce site. Currency is automatically exchanged at the price entered for the local currency.

  • Patent number: 5898602
    Abstract: An improved arithmetic logic unit (ALU) of an erasable-programmable logic device (EPLD) with a flexible, programmable carry function allows a broad range of functions to be implemented. The inventive circuit utilizes a separately configurable carry chain with multiple logic and arithmetic function capabilities.

  • Patent number: 5495196
    Abstract: The present invention allows initializing operations such as loading configuration data and preloading registers to begin before a user has released a reset signal. A circuit is provided which responds to the leading edge of a user's reset signal to generate an internal reset signal which begins the initializing operation. The circuit simultaneously starts a delayed signal which ends the internal reset signal. If the MRX signal is long, the chip becomes ready for operating upon release of the MRX signal, whereas if the MRX signal is short, the chip becomes ready for operating upon completion of any steps necessary for resetting the chip. In either case, after a reset signal is received, the chip becomes ready for operation in a shorter time than with the prior art circuits.
