splitting the zero - asset and liability
- Robert took a loan at RBS, so he signed a contract to repay RBS £10,000, which is legally enforcible, so RBS has an asset (Robert's promise).
- Robert, having committed to pay RBS £10,000 back, wants to receive his ‘loan’. So RBS opens up [a deposit] account for him, and types in £10,000. So, now RBS has a liability now as well (on Robert's demand, the money can be withdrawn from his deposit account).
