Abstract

Claims (39)

1 . A system including:

a processor; and

a non-transitory memory configured to store:

a non-legacy data structure;

a legacy data structure; and

instructions that, when executed by the processor, cause the processor to:

identify a participant data object defining a participant flow for participant, wherein the participant flow includes a non-legacy flow referenced to an active rate index;

when the participant flow is identical in magnitude and opposite in polarity to a net legacy flow associated with one or more legacy data objects associated with the participant, the net legacy flow referenced to an inactive rate index:

compress the participant data object and the one or more legacy data objects via:

 execution of a cross-linking of the participant data object with the one or more legacy data objects, the cross-linking including locking the participant data object to the one or more legacy data objects across the non-legacy data structure and the legacy data structure; and

 removal, responsive to the cross-linking, of the participant data object from the non-legacy data structure and the one or more legacy data objects from the legacy data structure.

2 . The system of claim 1 , wherein a start date for each of the one or more legacy data objects occurred before the inactive rate index became inactive.

3 . The system of claim 1 , wherein each of one or more legacy data objects have an identical flow execution date.

4 . The system of claim 1 , wherein the participant data object is characterized by a nominal notional amount to obviate a multi-step flow magnitude evaluation.

5 . The system of claim 1 , wherein at least one of the one or more legacy data objects includes a short-dated remainder data object resulting from compression of a long-dated legacy data object.

6 . The system of claim 1 , wherein the participant flow corresponds to an upfront fee with a magnitude equal to the magnitude of the net legacy flow, the upfront fee defined within the participant data object.

7 . The system of claim 1 , wherein the participant data object defines one or more legs of an interest rate swap for the participant and the participant flow includes a cashflow for the interest rate swap.

8 . The system of claim 7 , wherein the participant data object is generated along with a counter data object that defines one or more legs of the interest rate swap for a counter party.

9 . The system of claim 1 , wherein the participant flow includes a net non-legacy flow defined by a plurality of non-legacy data objects including the participant data object.

10 . A computer-implemented method for data compression, the method including:

identifying, by a processor, a participant data object defining a participant flow for participant, wherein the participant flow includes a non-legacy flow referenced to an active rate index;

when the participant flow is identical in magnitude and opposite in polarity to a net legacy flow associated with one or more legacy data objects associated with the participant, the net legacy flow referenced to an inactive rate index:

compressing the participant data object and the one or more legacy data objects by:

executing, by the processor, a cross-linking of the participant data object with the one or more legacy data objects, the cross-linking including locking the participant data object to the one or more legacy data objects across a non-legacy data structure stored in memory and a legacy data structure stored in the memory; and

removing, by the processor and responsive to the cross-linking, the participant data object from the non-legacy data structure stored in memory and the one or more legacy data objects from the legacy data structure stored in the memory.

11 . The computer-implemented method of claim 10 , wherein a start date for each of the one or more legacy data objects occurred before the inactive rate index became inactive.

12 . The computer-implemented method of claim 10 , wherein each of one or more legacy data objects have an identical flow execution date.

13 . The computer-implemented method of claim 10 , wherein the participant data object is characterized by a nominal notional amount to obviate a multi-step flow magnitude evaluation.

14 . The computer-implemented method of claim 10 , wherein at least one of the one or more legacy data objects includes a short-dated remainder data object resulting from compression of a long-dated legacy data object.

15 . The computer-implemented method of claim 10 , wherein the active rate index includes the Secured Financing Overnight Rate (SOFR) and the inactive rate index includes the London Interbank Offered Rate (LIBOR).

16 . The computer-implemented method of claim 10 , wherein the participant data object defines one or more legs of an interest rate swap for the participant and the participant flow includes a cashflow for the interest rate swap.

17 . The computer-implemented method of claim 16 , wherein the participant data object is generated along with a counter data object that defines one or more legs of the interest rate swap for a counter party.

18 . The computer-implemented method of claim 10 , wherein the participant flow includes a net non-legacy flow defined by a plurality of non-legacy data objects including the participant data object.

19 . A system for data compression, the system including:

means for identifying a participant data object defining a participant flow for participant, wherein the participant flow includes a non-legacy flow referenced to an active rate index;

means for compressing, when the participant flow is identical in magnitude and opposite in polarity to a net legacy flow associated with one or more legacy data objects associated with the participant, the participant data object and the one or more legacy data objects, the net legacy flow referenced to an inactive rate index the means for compressing including:

means for executing a cross-linking of the participant data object with the one or more legacy data objects, the cross-linking including locking the participant data object to the one or more legacy data objects across a non-legacy data structure stored in memory and a legacy data structure stored in the memory; and

means for removing, responsive to the cross-linking, the participant data object from the non-legacy data structure stored in memory and the one or more legacy data objects from the legacy data structure stored in the memory.

20 . The system of claim 19 , wherein the participant data object defines one or more legs of an interest rate swap for the participant and the participant flow includes a cashflow for the interest rate swap.
