> Insolvency is a state of financial distress in which a business or person is unable to pay their bills.

This isn't true. If you eat at a restaurant but forget your wallet, you can't pay your bill but you're still solvent. You have assets to cover your debts. "Can't pay your bill" is too broad a statement to be meaningful. There are many complicated financial instruments and needing time to make a payment doesn't automatically make you insolvent.
