Patent ID: 8676703

Claim:
An apparatus comprising: a processor; a first computer memory having stored therein data that defines an insurance policy as a plurality of discrete temporally-sequential policy data revisions, wherein each revision incorporates information from temporally prior revisions covering an effective date range of the revision; a second computer memory having stored therein a program which when executed causes the processor to: receive a new policy revision that is temporally subsequent as compared to a first policy data revision and that comprises a legally effective date range preceding at least in part an effective date range of the first policy data revision; divide the new policy revision into a plurality of legally non-overlapping policy data revision segments, wherein at least one of the legally non-overlapping unbound policy data revision segments has a legally effective date range that starts on an effective date of the new policy revision and ends on an initial effective date of the first policy data revision; determine, based at least in part on the legally non-overlapping unbound policy data revisions, effects of the new policy data revision.
