David,
As an aside, my insurance company wants a copy of my inventory ever time I renew the policy, so they have a history of fluctations in value and bottle count to look at.
And speaking about lightning striking, the insurance company thought that had happened the first time they asked me to fax a copy of all my wines purchases/sales/consumption records. Their fax machine damn near melted.

They now want the short version

so I export the records to Excel and send them the file electronicially.
